STUDY ON THE RELATIONSHIP BETWEEN LEISURE PARTICIPATION, VALUE AND MOOD REGULATION OF FESTIVAL PARTICIPANTS

BackgroundNowadays, we are in an era of national leisure. Festival is not only a cultural exchange activity, but also a way of public leisure. Festival participants usually have a strong curiosity about where the festival is held. They usually hope to let them know the lifestyle of a region through festivals like local residents. The theme of this study is the interactive relationship between participants' leisure participation, leisure value and their emotional regulation.Research Objects and MethodsBased on theoretical analysis, expert consultation and reference to the research of others, this study uses the self-made Richter five scale to investigate the leisure participation and leisure value of festival participants through the combination of online survey and on-site survey And three potential emotional variables and their relationships. Respondents are limited to those who have participated in festival activities. Finally, 420 valid questionnaires were collected and processed by statistical analysis software SPSS 26. 0 and Amos. Through reliability and validity test, goodness of fit test, structural model analysis and scale correction analysis, the final model path coefficient is obtained. Then, IPDE is a three-level score: 0 normal, l prominent, 2 in line with the diagnostic criteria and morbid. How long can a behavior last be considered as a personality trait? There is no unified view in the world. IPDE stipulates at least 5 years. ICD-10 requires at least 3 items for each type of diagnosis, while DSM-IIIR requires 4-5 items, and the score of at least one item is 2 points. If the positive score is more than 10 (one score is also required to be 2), but it does not meet any kind of network cognitive impairment, it will be diagnosed as other types of personality. No matter what kind of diagnostic system, it requires at least one item that meets the diagnostic criteria, and the behavior described has appeared before the age of 25. Who has developed a set of software for IPDE. As long as the score of each item is entered, the result can be obtained.ResultsThe empirical study found that the subjects were mainly behavioral participation. Participating in festival activities has good psychological, cultural and social values. Leisure participation has a more significant impact on leisure value, followed by leisure value on psychological well-being, followed by leisure participation on psychological well-being, but the three groups have reached a significant level and interact with each other, indicating the leisure participation, leisure value and mental health of festival participants. Leisure value is an intermediary variable. After the change of leisure participation, the impact on emotion is more significant.ConclusionsParticipants' leisure participation in festival activities is the basis for realizing value and creating happiness. People can choose some brand festivals and well-known festivals according to their time, energy and hobbies, actively participate and enrich their life experience. Improve the quality of your life. The deficiency of this study is that the representativeness of the sample needs to be further optimized. This study will help festival organizers summarize their successful experience and shortcomings, constantly explore new operation ideas, improve and promote their own operation mode, give full play to their respective advantages, mobilize the enthusiasm of the masses, and then design various forms of activities. The content adapts to the local environment and serves cultural exchanges.AcknowledgementsSupported by a project grant from key scientific research project of higher education institutions in Henan Province (soft science) (Grant No.22B630034).

EXPLORING AND CONSTRUCTING AN EFFECTIVE EVALUATION MODEL OF NETWORK TEACHING FROM THE PERSPECTIVE OF EMOTION REGULATION

BackgroundAffected by the epidemic, the online teaching of “Internet + intelligence” technology has broken the traditional teaching mode and realized the multi-dimensional, intelligent and in-depth interaction and integration between learners, teachers and online learning resources. It has become an important development direction of higher education in China and even the world. Network teaching has changed from “fresh” to “new normal”.Topics and MethodsUsing the methods of literature review, system analysis and PDCA cycle model, determine the design and evaluation of network teaching, and explore an effective evaluation model of network teaching from the perspective of educational psychology, so as to promote teaching practice. This study takes 200 freshmen in a university as the research object to study the College Chinese anxiety, self-efficacy and achievement level in online teaching. The score of the Chinese final exam is used to divide participants into pass group and fail group. Both gender and major are considered as variables of language achievement. This study includes four elements of self-efficacy: learning ability, courage to overcome challenges, effort and overcoming setbacks. Through t-test, univariate and multivariate analysis of variance and regression analysis, we investigated the relationship between foreign language anxiety, self-efficacy and academic achievement of students of different majors and genders.ResultsGenerally speaking, students' attention to online teaching evaluation fluctuated and increased, but there is still no core author group and close institutional cooperation network. The frontier fields of network teaching evaluation research mainly include evaluation theory and technology research, quality and effect research, quality influencing factors research, teaching design evaluation research and evaluation methods research. The research hotspots of network teaching evaluation mainly include the research on the concept and connotation of network teaching evaluation, the evaluation of network teaching environment and technology, the evaluation of network teaching curriculum and teaching process, and the evaluation of network teaching effect. However, teaching quality has become the bottleneck restricting the development of network teaching. It is difficult to see the whole picture of effective network teaching. Considering the space limitations of network teaching, there are many blind spots in the evaluation of teachers' network teaching effect. This paper formulates an effective network teaching evaluation model framework, constructs an effective network teaching standard evaluation content, and puts forward the implementation path of standard evaluation, which provides a strong guarantee for the high-quality development of network teaching. The results show that the learning anxiety level of the improvement group is significantly lower than that of the failure group, and the self-efficacy level of the pass group is significantly higher than that of the failure group. Compared with the male group, the female group's language achievement and self-efficacy level are much higher. However, there was no significant difference in anxiety levels between men and women. In addition, the study also found that foreign language anxiety was negatively correlated with foreign language achievement. Similarly, there is a significant negative correlation between foreign language anxiety and self-efficacy. State anxiety, trait anxiety and foreign language learning anxiety are positively correlated. The anxiety component of learners' personality characteristics plays an important role in the generation of foreign language learning anxiety. There was no significant difference between the experimental group (M = 2.528, SD = 0.540) and the control group (M = 2.695, SD = 0.858); There was no significant difference between the experimental group (M = 2.778, SD = 0770) and the control group (M = 2.556, SD = 0.808); There was no significant difference in the total score of emotion regulation self-efficacy between the experimental group (M = 35.083, SD = 5.931) and the control group (M = 35.500, SD = 5.551).ConclusionRealizing the standardization and standardization of the whole chain of the purpose, process and results of online teaching will help teachers clarify this process and knowledge system, improve the standards and practical ability of effective online teaching, and integrate new technologies such as artificial intelligence into the process of online teaching and online teaching evaluation, which has attracted the attention of more and more researchers and can greatly improve the learning quality of students, It provides a reference for the orderly development of online teaching activities.AcknowledgementThis research was supported by Heilongjiang Higher Education Teaching Reform Project “Exploration and Practice of Online Teaching Mode for Effective Learning” (Grant No. SJGZ20200094), Heilongjiang Postdoctoral Scientific Research Developmental Fund (Grant No. LBH-Q20107), Heilongjiang Basic Scientific Research Project (Grant No. 2020KYYWF-FC12), and Harbin Sport University Doctoral Scientific Research Start-up Fee Project (Grant No. RCYJ-2104).

ON THE GENERALIZATION OF PHYSICS CURRICULUM TO SCIENCE EDUCATION AND POPULAR SCIENCE FROM THE PERSPECTIVE OF EMOTION REGULATION

BackgroundScience Education in China is a way to improve citizens' scientific and technological literacy. It also popularized physics that promoted innovation. The deep popularization of physical science is an important content of science education. Therefore, it is necessary to explore the logical relationship and practical path between science education, college physics curriculum and science popularization, that is, the generalization of physics curriculum to science education and popular science from the perspective of emotional regulation.Subjects and MethodsApply Bruner's cognitive structure learning theory in psychology to college physics teaching, and transform the basic structure of physics into the cognitive structure of physical theories and phenomena in students' minds. In order to coordinate the development of physics courses and the popularization of science, the basic physics courses and majors of the University have been adjusted to help students understand the principles of physics and apply them to engineering. A total of 415 junior middle school students in three grades of an experimental middle school were investigated by cluster stratified sampling. The emotional regulation ability scale compiled by Lu Jiamei and Ji Jiajun (2010), the Chinese version of emotional behavior scale (PBI) revised by Yang Hongjun (2009) and the Chinese version of aggressive behavior (BWAQ) (2008) were used as research tools, and spss17 0 to analyze the data results by descriptive analysis, analysis of variance and linear regression.ResultsWe found that while widely spreading science and technology, cultivating citizens' awareness of science and technology is a necessary condition for further popularizing science. We have identified four aspects of in-depth popularization of science. We have also created a four part physics course and created a teaching method that combines online and offline teaching, large and small classes, as well as theoretical and practical learning. Using various forms of science education, we have constructed three ways to provide ideological education in the curriculum. In the practice of many science education, we have not only proved that the most important part of physics education is scientific and technological literacy, but also formed the soul of basic physics curriculum: “explore laws after encountering phenomena, respond to principles creatively, and pursue loyalty and accuracy”. Based on the teaching philosophy and objectives of Xi University of technology, and taking two innovative points, three characteristic physics courses and popularization as the main line, this paper explores 30 elements of ideological education related to “physics, weapon industry and calligraphy”. These reforms were highly praised by the heads of 15 engineering majors related to the ordnance industry, and helped 13 engineering majors obtain China's higher engineering education certification.ConclusionAfter 10 years of educational practice, we have developed the physics curriculum to the stage of in-depth popularization of science. In the full combination of physics curriculum and engineering teaching, it embodies the three-stage learning process of acquisition, transformation and evaluation in Bruner's psychological theory. The scientific and technological literacy of Chinese teenagers has improved. In short, we should fully consider the important influence of emotion, actively pay attention to the changes of psychological emotion and behavior in their learning, and strive to become the manager, coordinator and collaborator of curriculum construction.We should actively organize rich activities flexibly according to the psychological characteristics of this part of the group, strive to build a relaxed and harmonious living atmosphere, create a friendly and mutual aid relationship, encourage and guide this part of the group, adjust the psychology to the best state, and promote the healthy growth in a good learning life.AcknowledgementsThe paper was supported by the Shaanxi Social Science Foundation Project of P.R.C (Grant No.2021P022).

THE CONSTRUCTION OF SELF-IMAGE OF THE SUBJECT OF POST-NATIVE CULTURE FROM THE PERSPECTIVE OF EMOTIONAL BEHAVIOR CHANGE

Background“Houtu” is the most unique cultural symbol and emotional link in the inheritance of agricultural cultural beliefs in ancient China, and it is also one of the important components of contemporary folk culture. Belief has been a unique psychological phenomenon of human beings since ancient times. It reflects human belief and compliance with the world outlook, outlook on life and values through psychological activities. “Houtu belief” originated from people's worship of land and first appeared in ancient agricultural society. Shanxi fenyin is the birthplace of “Houtu belief”, which is regarded as “the oldest ancestor and the most outstanding God in China”. Its temple is also a place for emperors of each dynasty to make pilgrimages and worship gods. It is also regarded as the crown of Houtu temple in China and the source of Houtu Royal worship. At the same time, with the rise of the study of regional emotional change, this study also helps to better understand the later beliefs.Subjects and MethodsStarting with the investigation of Houtu temple in fenyin County, Shanxi Province, this paper puts forward some problems, such as divine gender, image transformation and so on. From the pre Qin Dynasty to the early Western Han Dynasty, the Houtu God was the God of men, but now the Nuwa statue in Wanrong Houtu temple is the God of women. What's the reason? In view of this, this paper examines the evolution process and function of backland image from the perspective of belief psychology, and probes into its contemporary artistic value. In addition, this paper also uses Likert scoring method to evaluate the scale. Pearson correlation, standard deviation and statistical significance are combined to illustrate the correlation. The t-test of independent samples was used to verify the differences between male and female believers. According to the statistical value of emotion, participants were divided into three groups: low, medium and high groups. The questionnaire includes two kinds of anxiety, namely debilitating emotion and promoting emotion. Through t-test, univariate and multivariate analysis of variance and regression analysis, we investigated the relationship between time span, psychological activities and social status of believers of different beliefs and genders.ResultsAccording to the conclusion of this paper, the evolution of Houtu culture is an interactive process between objective social environment and subjective belief psychology. The image of Houtu culture and its belief activities have experienced a relatively unique cultural evolution process. The study studied male god believers and goddess believers, and found that compared with male god believers, goddess believers have much higher social status and audience. However, there was no significant difference in emotional level between male and female gods.With the development of society, it is gradually socialized and official. The image of backland has been recognized, re understood and recognized in the historical changes in order to adapt to and deal with social and cultural beliefs and historical context. It creatively reforms and integrates the national historical and cultural traditions and the social practical experience of various times, and constructs a new cultural form that respects the tradition and reflects the social practical experience.ConclusionsNowadays, in the multicultural context, “Houtu belief”, as a new national custom and cultural event, not only ensures the cultural legitimacy of Houtu culture in the local society, but also continues the inseparable relationship and memory between them and their ancestral civilization. It provides a new theoretical perspective and practical basis for the later research in the multicultural context. It can also promote the use of psychology to broaden the direction of studying national customs and culture.AcknowledgementSupported by the following projects, 2019 Jinzhong University “1331 Project” innovation team “Shanxi Cultural Heritage Inheritance and Provincial Cultural Tourism Strengthen Provincial Strategy Research” (JzxycxTD2019002). 2020 Shanxi Philosophy and Social Science Research Project: Research on animal Images of Chinese Buddhist Art (2020W184).

RESEARCH ON THE REGULATION OF MULTI-AGENT'S EMOTION BASED ON MULTI-AGENT'S HETEROGENEOUS GAME PREFERENCE AND BILATERAL PARTNER'S PREFERENCE

Abstract Background The development of virtual enterprise is inseparable from the support of partners. Due to information asymmetry, the choice of virtual enterprise partners is blind, and simple matching formula is difficult to meet. At the same time, the psychology of the matching subject is based on the maximization of its own interests rather than the maximization of collective interests. There are interest contradictions and conflicts between subjects, and they may eventually fall into a “prisoner's dilemma”. Therefore, how to carry out the research on emotion regulation based on multi-agent heterogeneous game preference and bilateral partner preference is very important. Research Objects and Methods Aiming at the contradictions and interest conflicts between subjects in the process of virtual enterprise partner matching, combined with the basic characteristics of subject language preference evaluation, the game idea is introduced into the process of virtual enterprise partner bilateral matching analysis, a bilateral matching game model of heterogeneous multi-attribute preference and subjects' psychological behavior is proposed, and the influence of the changes of subjects' psychological behavior on the evolution law of bilateral matching game system is analyzed, The Nash equilibrium strategy of bilateral matching is discussed. In order to verify the impact of the algorithm on emotion, this study uses relevant scales to investigate. (1) Positive emotion scale. The Panas emotion scale developed by Watson et al. Is widely used to measure emotion. The scale includes two dimensions: positive emotion and negative emotion. There are 6 questions in this dimension, and Likert scores 5 points (1 means “very inconsistent”, 5 means “very consistent”, the same below). The Cronbach coefficient of this questionnaire is 0.90. (2) Motivation. The problem of measuring motivation is mainly the motivation scale compiled by Phan, which has 8 questions and is scored with Likert 5 points. (3) Social support scale. The scale is adapted from the social support scale compiled by Ye Yuemei et al. It has eight questions, using Likert's five points scoring method. Clonbach α the coefficient of the scale is 0.87. (4) Behavioral propensity scale. Propensity dimension in intention measurement. The scale has 6 questions, and Likert scores 5 points. The clonbach coefficient of the scale is 0.95. Results The results of case analysis show that the model can make full use of the multi-attribute preference information of heterogeneous subjects, describe the mechanism of psychological behavior affecting the evolution of game system, and help virtual enterprises match business partners; This has important value and significance for the establishment of virtual enterprises and their industrial agglomeration effect. In the influence process of cooperative anxiety, emotional response plays an intermediary role, psychological elasticity plays a regulatory role, and emotional response to life events plays an intermediary role. That is, the higher the psychological elasticity, the higher the excessive coping style of the game, and vice versa. Conclusion Various stable matching solutions can be obtained by solving the model, and the conclusion is more suitable for the matching decision-making process of both parties in the actual process, which makes the model can be applied to various scenarios, such as the selection of battery suppliers of new energy vehicles and smart phone screen suppliers, which has greater practical value and significance. It should be pointed out that there are some deficiencies in the setting conditions of the model method, mainly because some individuals in the group cooperate to form an alliance, so as to form a community of interests. In the process of game, the individual experience in the group is constrained by more conditions, which makes the results of the model deviate.

Numerical Investigation of Supporting Electrolyte Using in a Vanadium Redox Flow Battery

The vanadium redox flow battery (VRFB) store chemical energy and generate electricity by redox reactions between vanadium ions dissolved in electrolytes. The main components of VRFB are positive and negative porous electrodes, membrane, current collectors, electrolyte, and pumps. The electrolyte is composed of vanadium species and supporting electrolytes. The supporting electrolyte has two main functions: 1) to increase the electrolyte's ionic conductivity, and 2) to deliver hydrogen ions to the positive electrode reaction. The supporting electrolytes are many kinds of an acid such as sulfuric acid, hydrochloric acid, methane sulfonic acid, etc. Some study has been done to improve the performance of VRFB a mixed electrolyte supporting. Zhang et al. proved that the stabilities of vanadium ions in sulfuric acid solution could be improved marginally by adding some additives as stabilizing agents 1. Sha et al studied the effect of organic additives on positive electrolyte for vanadium redox battery They found that the energy efficiency for the electrolyte with D-sorbitol was higher than that electrolyte without additives 2. Chang et al investigated coulter dispersant IIIA additive into the positive electrolyte 3. The obtained result showed that the coulter dispersant IIIA increased the stability of the positive electrolyte in VRFB.According to the authors' knowledge, there is no a numeric study that comparing, the supporting electrolyte used in a VRFB. The aim of this study is to perform comparatively a numerical analyze of the supporting electrolyte of H2SO4 and HCl in the negative and positive electrodes. To achieve these objectives a two-dimensional model is developed with COMSOL Multiphysics under some assumptions and boundary conditions. The electrolyte potential is deeply investigated through the state of charge (SOC).The simulation result shows that the difference in the electrolyte potential between the supporting electrolyte of H2SO4 and HCl, the supporting electrolyte of H2SO4 possesses a higher potential compared to the HCl. This phenomenon is strongly related to the number of hydrogen protons delivered by the supporting electrolyte of H2SO4 which is more compared to that of HCl 4.

Factors affecting acceptance of palliative care in mainland China: a national cross-sectional study

China ranks 53rd in the list of 81 countries included in the Quality of Death and Dying Index 2021. Cancer is one of the leading causes of death in China. Although the country is highly burdened with cancer, with 4·5 million new diagnoses and more than 3 million cancer deaths in 2020 alone, palliative care services in mainland China are extremely scarce. The aim of this study was to investigate the attitudes of people towards palliative and hospice care, and to analyse the associations between attitudes and potential explanatory variables. A survey was done between July 10, 2021, and Sept 15, 2021. We used a multistage sampling strategy to recruit participants from 120 cities across mainland China. The questionnaire aimed to assess the willingness of respondents to receive palliative care. Survey data were analysed by multiple stepwise linear regression to establish the factors associated with willingness to receive palliative care. Sex, education level, possession of a house, perceived anxiety on the Generalised Anxiety Disorder Assessment scale, perceived pressure, social support (evaluated through the Perceived Social Support Scale), family health (evaluated through the Short-Form Family Health Scale), health literacy (evaluated through the Short-Form Health Literacy Questionnaire), personal sense of health (evaluated through the EuroQol Visual Analogue Scale), self-reported quality of life and sense of health (evaluated trough the EuroQol Five Dimensions Questionnaire), and access to medical insurance were analysed as potential explanatory variables affecting acceptance of palliative care. Standardised regression coefficients (β) were used in multiple stepwise linear regression to reflect the effect of variables on the results. 11 031 respondents completed the survey. The average willingness to accept palliative care was scored at 65·02 points in a visual analogue scale of 0-100 points. Men (β=-0·02) were more likely than women to decline having palliative care. Respondents holding a bachelor's degree or higher (β=0·04), owning more residential properties (two: β=0·02; three or more houses: β=0·01), self-reporting mild perceived anxiety (β=0·03), higher perceived pressure (moderate pressure: β=0·05; severe pressure: β=0·06), or higher scores on the Perceived Social Support Scale (β=0·10), the Short-Form Family Health Scale (β=0·12), the Short-Form Health Literacy Questionnaire (β=0·16), the EuroQol Visual Analogue Scale (β=0·21), the EuroQol Five Dimensions Questionnaire (β=0·05), or with access to medical insurance providing higher reimbursement (employee health insurance and commercial health insurance: β=0·03; government insurance: β=0·04) were more willing to accept palliative care. Sex, house ownership, perceived anxiety, perceived pressure, social support on the Perceived Social Support Scale, and health literacy were the main affecting factors on Chinese residents' acceptance level and attitudes towards palliative care identified by this study, in which we discuss the public acceptance of palliative care on the basis of a nationwide sample from China. Despite some substantial reported outcomes in palliative care, the study is limited by reporting bias and selection bias.

Soviet Industrial Sociology, 1960s-1970s

To understand the rapid development of Soviet industrial sociology in the 1960s, it is essential to look beyond the Academy of Sciences in Moscow and focus instead on very specific local environments where higher educational institutions established sociological research institutes. The institutes’ work comprised scientific research projects and numerous projects carried out under economic contracts with industrial enterprises. The latter certainly supported the rapid growth in the numbers of institutes and sociologists in the 1960s and 1970s. However, there were significant constraints in redeploying the project results for academic purposes. In addition, sociology more broadly turned towards ideological conformism from 1972. As a result, the institutes’ scientific leaders focused on constructing a consensus around the methodology of sociological research.

Methodological trauma in the socio-humanitarian sciences

The article raises the issue of the state of logic and methodology of socio-humanitarian researches in modern Ukraine. It is diversely argued the canonical requirement to return the preparation of scientific research projects and subsequent publication of their results and conclusions to generation in them such a conceptual structure (writing an introduction), which necessarily contains a normative formulation of the scientific problem in the form of a theoretical question concerning cognitive contradictions resulting from the existing practices of obtaining new rational knowledge in accordance with the three types of epistemological matrix of sociological cognition, which determine one of the research positions – to be an observer, interpreter or activist. Emphasis is placed on the tendency of reducing the demands concerning mandatory presentation of the methodological basis of the study in its program, reports, publications on the results obtained, in particular concerning the normative design of articles published in Ukraine’s professional journals in sociology. Examples of violations of this norm are given in articles published during 2015 and 2016 in two leading domestic periodicals of sociological orientation. It is noted that the claims of some authors to the theoretical significance of their publications are not justified in the absence of a scientific problem statement, the formulation of which must include a number of issues of theoretical content. In addition, it is underlined that the current situation in Ukrainian sociology can be explained by the so-called methodological trauma, which is also typical for researchers from other post-Soviet countries. The conclusion is formulated that the development of sociological science in its theoretical and empirical contexts is possible only if the methodological trauma experienced by sociologists, psychologists and other representatives of socionomic research role is overcome.

P-550 Transgenerational epigenetic influences of maternal circadian rhythm changes during pregnancy and lactation periods on cognition and behavior in male offspring

Abstract Study question Do maternal circadian rhythm changes during pregnancy and lactation periods cause transgenerational behavioral and cognitive alterations in male offspring? Summary answer Maternal circadian rhythm changes cause impaired behavioral alterations such as motor activity impairments, increased anxiety and weakening of spatial memory in male offspring. What is known already The circadian system regulates the daily temporal organization in behavior and physiology in most species. Recent publications in model systems have emphasized the negative effects of circadian rhythm disruption on both female and male reproduction and fertility. There is growing concern about the long-term effects of circadian rhythm disruptions during pregnancy and lactation periods on human offspring and their descendants as circadian regulation during these periods can potentially alter epigenetic programing in offspring. However, there is a lack of information about the possible transgenerational effects of circadian rhythm disorders for the health of offspring in the literature. Study design, size, duration Male offspring from pregnant Wistar rats (n = 60) which were exposed to control (12 hours light/12 hours dark), short day (SD) (8 hours light/16 hours dark) or long day (LD) periods (16 hours light/8 hours dark) during only pregnancy, only lactation or both periods (n = 15/group) categorized as control, SD pregnancy (SD-P), SD lactation (SD-L), SD pregnancy and lactation (SD-P+L), LD pregnancy (LD-P), LD lactation (LD-L), LD pregnancy and lactation (LD-P+L) groups. Participants/materials, setting, methods The length of gestation, litter size, sex ratio of pups (fraction male) and birth weights were recorded. The maternal locomotor activity and anxiety were analyzed by open field (OF) and elevated plus maze (EPM) tests, respectively (n = 15 mothers/group). Learning and memory, locomotor activity and anxiety related changes were studied in the male offspring in pre-pubertal, pubertal and adult periods with object localization (OL) and Morris water maze (MWM), OF and EPM tests, respectively. Main results and the role of chance Newborn weights was significantly increased in SD (5.01±0.07) and LD (4.47±0.29) groups compared to control group (3.73±0.03) (p < 0.001). Male sex ratio of pups born to mothers on SD schedule was unusually low (0.21±0.62) compared to mothers on normal light schedule (0.48±0.05) (p < 0.001). The gestation length was not altered. Locomotor activity was increased in mothers exposed to SD schedule (p < 0.01). A significant motor activity impairment in the prepubertal period was remarkable in SD-P+L, LD-P, LD-L and LD-P+L groups (p < 0.001). Compared to control group, EPM test showed that all the offspring in SD groups had significant increase in their anxiety in the prepubertal period. Motor functions that decreased before puberty seems gradually improved at adulthood. Weakened short-term spatial memory was observed at puberty, especially in SD-P (p < 0.001), SD-P+L (p < 0.05), LD-P (p < 0.05) groups. Time to find the platform was significantly higher than those measured for control group for SD-P-L (p < 0.001) in the prepubertal period and LD-P+L group (p < 0.001) in the pubertal period meaning decreased spatial memory and learning. A probe trial given on day 6 with MWM test showed that LD groups had no alterations in spatial memory whereas SD-P (p < 0.05) and SD-G+L (p < 0.001) groups showed impaired changes in long-term spatial memory. Limitations, reasons for caution Due to limitations of working with human subjects exposed to shift work schedules, most chronoregulation research including ours has used rodent models with limitations in translating to human studies. However, to truly know if such concerns apply to humans will require retrospective and prospective human studies. Wider implications of the findings Epigenetic transitions are crucial for transcriptional reprogramming triggered by environmental cues. Our study might provide valuable information regarding transgenerational effects of maternal chronodisruption on health later in life of the offspring, particularly at prepubertal and pubertal periods, create suggestions and guidelines for reproductive biology, shift work and possible infertility problems.

P-114 Transgenerational effects of maternal circadian rhythm changes on DNA methylation pattern in the testis of offspring rats

Abstract Study question Does maternal circadian rhythm change during pregnancy and lactation cause transgenerational epigenetic changes on DNA methylation in the gonads of adult male offspring? Summary answer The expression of DNA methyltransferases (DNMTs) is altered in the testis of offspring rats due to maternal circadian rhythm changes during pregnancy and lactation periods. What is known already Epigenetic mechanisms are essential for normal development and maintenance of tissue specific expression in mammals. Key mechanisms involved in epigenetic gene regulation include specifically DNA methylation and histone modifications. DNA methylation is an important regulatory mechanism that plays a role in many cellular processes and it is catalyzed by specific DNMT enzymes. Regulation of the circadian clock is also subject to epigenetic influence. Current evidence increasingly indicates that environmental conditions during pregnancy may have lifelong effects on offspring in both humans and animal models. Study design, size, duration Male offspring from pregnant Wistar rats (n = 60) which were exposed to control (12 h light/12 h dark), short day (SD) (8 hours light/16 hours dark) or long day (LD) periods (16 hours light/8 hours dark) during only pregnancy, only lactation or both periods (n = 15/group) categorized as control (C), SD pregnancy (SD-P), SD lactation (SD-L), SD pregnancy and lactation (SD-P+L), LD pregnancy (LD-P), LD lactation (LD-L), LD pregnancy and lactation (LD-P+L) groups. Participants/materials, setting, methods Maternal body weights were recorded during pregnancy and lactation periods. The global methylation pattern was evaluated with 5-methylcytosine (5-mC) immunostaining in line with histopathological analyzes in the testis tissues. In addition, the expression of three DNMTs, DNMT1, DNMT3A and DNMT3B, were evaluated to analyze the maintenance of DNA methylation and de novo establishment of DNA methylation patterns, respectively. Main results and the role of chance DNMT1 immunolocalization showed a nuclear staining pattern, predominantly in spermatogonia, spermatocytes, round spermatids and Sertoli cells in all experimental groups. A significant increase in DNMT1 expression was determined in SD-P, SD-L, SD-P+L, LD-P and LD-L groups compared to the control group (p < 0.001). On the other hand, DNMT3A was especially expressed in spermatogonia, spermatocytes, and Leydig cells in the interstitial areas. Spermatogonia, round spermatids and the head of elongated spermatids and also in Leydig cells in the interstitial areas were immunopositively stained with DNMT3B and 5-mC. 5-mC expression was also present in spermatocytes. There was a significant increase in DNMT3A, DNMT3B and 5-mC expressions in SD-P, SD-L and SD-P+L groups compared to the control group (p < 0.001). DNMT3B and 5-mC expressions were statistically higher in LD-P than control group (p < 0.001). Limitations, reasons for caution Although using a rat model has several advantages, translating these results to the human setting is a limitation of this study. Wider implications of the findings The recent studies regarding circadian regulation in reproductive tissues suggests that it plays important role in several aspects of fertility. Our study indicates that expression of DNMT proteins alters in testis due to maternal circadian rhythm changes suggesting potential influences on transgenerational reproductive health of offspring.

The Impact of Risk Perception Difference of Members of a Scientific Research Project Team on Information Adoption: The Moderating Effect of Knowledge Inertia

A scientific research project is always full of uncertainties and risks. In this condition, full exchange and complementarity of information resources among project team members are necessary and important to meet the information needs for project risk management and even affect the success of the project. The differentiated risk perception of members with various professional backgrounds can contribute to the communication and complementary of the necessary information within the team. However, too much difference in perceptions of project risks may cause members’ information conflicts, which may hinder the adoption of various information and do harm to the risk management. Considering the limited research on this “contradictory” relationship, especially for the scientific research project team, a special group, this study explores the impact of the risk perception differences of the scientific research project team members on information adoption behavior through the large sample empirical statistical method. The results show the hat risk perception difference of members positively affects the learning willingness and information adoption behavior but does not show a negative effect, and there is no inverted U-shaped relationship. Further, learning willingness plays a mediating role between both, while learning inertia and experience inertia positively and negatively moderate the positive effects of risk perception differences on learning willingness, respectively. From the cognitive perspective, this study further reveals the internal influence mechanism of risk perception difference of scientific research project team members on information behavior and provides a theoretical reference for improving the efficiency of information communication and optimizing collaborative team management.

The Influence of the Quality of Digital Elevation Data on the Modelling of Terrain Vehicle Movement

This study investigated digital terrain models and options for their evaluation and effective usage. The most important result of this study was the introduction of the slope reduction method for low-detail elevation models. It enabled accurate results of passability analyses by performing adjustments of slopes. In addition, the goal was to determine the strengths and weaknesses of selected data for use in cross-country mobility analyses, followed by recommendations on how to use these databases efficiently to obtain accurate results. The selection of elevation databases (1 m, 5 m, 10 m, 30 m) was determined by the focus of data development projects of NATO and current scientific research projects of the Ministry of Defence of the Czech Republic. Key findings showed potential for use in practise for all tested elevation models. Efficient usage of low-detail models in CCM analyses is limited; nevertheless, they can be augmented with additional vector data or automated remote-sensing technologies.

The unreachable doorbells of South Texas: community engagement in colonias on the US-Mexico border for mosquito control

Mosquitoes and the diseases they transmit continue to place millions of people at risk of infection around the world. Novel methods of vector control are being developed to provide public health officials with the necessary tools to prevent disease transmission and reduce local mosquito populations. However, these methods will require public acceptance for a sustainable approach and evaluations at local settings. We present our efforts in community engagement carried out in colonias of the Lower Rio Grande Valley in south Texas for mosquito surveillance, control, and ecological projects. Along the US-Mexico border the term colonia refers to impoverished communities that are usually inhabited by families of Hispanic heritage. The different engagements were carried out from September 2016 to February 2019; during this time, we had three distinct phases for community engagement. In Phase 1 we show the initial approach to the colonias in which we assessed security and willingness to participate; in Phase 2 we carried out the first recruitment procedure involving community meetings and house-to-house recruitment; and in Phase 3 we conducted a modified recruitment procedure based on community members’ input. Our findings show that incorporating community members in the development of communication materials and following their suggestions for engagement allowed us to generate culturally sensitive recruitment materials and to better understand the social relationships and power dynamics within these communities. We were able to effectively reach a larger portion of the community and decrease the dropout rate of participants. Progress gained with building trust in the communities allowed us to convey participant risks and benefits of collaborating with our research projects. Community engagement should be viewed as a key component of any local vector control program as well as for any scientific research project related to vector control. Even in the face of budgetary constraints, small efforts in community engagement go a long way.

Robotic autonomous asset management: benefit/value-based business model creation

Research has shown that value generation is an important factor when it comes to driving technological change. It follows that business models as narratives of value generation and capture have an important part to play as the end goals in the change process. Research also suggests, however, that the understanding of when, why and how value accrues to stakeholders, and what value to create, appears to be lacking. This paper describes an objective and repeatable methodology for the identification of benefit- and value-generating opportunities that can be used to aid business model creation. The methodology is demonstrated for the generic business of infrastructure asset management and discussed in detail in the context of ‘Pipebots’, a current scientific research project into the introduction of robotic and autonomous systems to the asset management of buried water and sewage pipe networks in the UK. In conclusion, the paper proposes that the methodology opens the door to a future where radical change in a given infrastructure system can lead to value capture across the wider system of systems.

In this report, a scientific research project is presented that is done for 2022 Massachusetts State Science Fair (MSEF) on rubber bands. This research work shows how the effect of temperature and pressure can change elasticity of the rubber bands those are found at home and used in everyday life. This work is done during COVID 19 time and shows how hands on activities can be performed to continue research work at home or in limited resources when it is not possible to go out very frequently. It is found after experimentation that rubber bands show more flexibility with lower spring constant and stop obeying Hooke’s Law on lower values of force applied to them under conditions of high pressure and temperature.
