Beyond conservation: Assessing broader development outcomes of protected areas in Nepal

Protected Areas (PAs) are set aside for biodiversity conservation but at the same time they are recognized for their role in supporting development goals. However, the benefits provided by PAs also come with costs to local people. Integrated Conservation and Development Projects (ICDPs) are a PA management approach that aim to maximize local benefits through enhancing conservation and development outcomes, while also reducing costs. We implemented a household level survey in two PAs in Nepal managed using an ICDP approach to assess local people's perceived benefits and costs and determine if this approach was achieving its intended outcomes. Since both PAs are popular nature-based tourism (NBT) destinations, respondents were asked questions specific to this activity and others more general to the PA. The coded qualitative responses revealed ten categories of benefits and twelve categories of costs. Most respondents perceived extraction benefits from PAs, and when asked to reflect specifically on NBT, they mostly identified economic benefits. Crop and livestock loss was the main perceived costs from PAs, whereas sociocultural costs were the main costs from NBT. Chi square tests showed that proximity to the PA office and residency status had the most significant differences in perceptions of benefits and costs from both PAs and NBT. People perceived very few benefits related to participation, cost mitigation, and conservation, which does not match the intended outcomes of ICDPs. Although there may be practical implications for engaging distant communities in management, this may help to enhance conservation and development outcomes from PAs.

Patient-Centered Outcomes With a Multidisciplinary CKD Care Team Approach: An Observational Study.

Multidisciplinary chronic kidney disease (CKD) care has been associated with improved clinical outcomes in comparison to general nephrology care. However, there is little research examining the impact of multidisciplinary care on patient-centered outcomes. We examined if a multidisciplinary approach to CKD care was associated with 4 patient-centered outcomes. Cross-sectional study design using previously established surveys to assess patient-centered outcomes in participants with nondialysis CKD. Adults with CKD stages 1-5 who had not undergone transplant or were not on dialysis. General nephrology care or multidisciplinary care. Patients receiving multidisciplinary care were seen by a pharmacist, social worker, dietitian, and nephrologist, whereas patients receiving general nephrology care only saw a nephrologist. Four patient-centered outcomes: CKD-specific knowledge, disease-related stress, perception of overall health, and perception of health status compared to 1 year ago. Differences were examined using a Welch 2-sample t test and linear regression model. Mean age of participants was 60 years with standard deviation of 17 years. 182 (77%) patients were White, and 230 (96%) had formal education greater than or equal to high school. 121 (49%) were women, and 215 (88%) had CKD stage 3-5. 77 (31%) received multidisciplinary care. We did not identify any significant differences in patient knowledge, stress, or perception of health between multidisciplinary and general nephrology care. However, notably, patients in multidisciplinary care were older and had more advanced CKD than those in general nephrology care. Cross-sectional study designs only identify associations. Study was conducted at clinics located within 30 miles of each other, limiting generalizability. Our results suggest that a team-based approach to care can better support sicker, more vulnerable patients so that they can achieve similar patient-centered outcomes compared to patients who are younger and with less advanced CKD.

Meta-analysis of Influential Factors on Perception toward Stuttering

Objectives: A very diverse group of people have negative perception toward stuttering. However previous studies have shown inconsistent results regarding influential factors on such perceptions toward stuttering. The primary purpose of the current study was to determine whether there are differences in perceptions toward stuttering according to various factors by meta-analysis.Methods: A total of four databases (two Korean and two English databases) were used for the article search in the current study. A total of 42 articles (33 English, 9 Korean) met the inclusion criteria and were analyzed in the current study. Effect sizes (Hedge’s g) were calculated for each outcome and combined for meta-analysis.Results: There was a significant difference in the perception toward stuttering according to overall influential factors. Furthermore, there was a significant difference in perception according to familiarity, education, and areas. However, there was no significant difference in perception according to other factors such as gender of the speaker and listener, occupation, age, career year, stuttering acknowledgment and stuttering severity.Conclusion: The meta-analysis results of the current study showed that the perception toward stuttering is stereotypic but can be modified. Furthermore, more intentional and long-term efforts are needed in order to positively change perception toward stuttering.

Differences in the visual perception of the upper dental midline deviation between orthodontically completely treated and untreated patients

ABSTRACTIntroduction: A common reason for people to obtain orthodontic treatment is a misalignment between the upper dental midline and the midline of the face. The process of orthodontic treatment is considered to affect a patient's visual perception before and after the treatment, as well as their satisfaction with treatment, possibly due to the information received during treatment. This study aimed to analyze this visual perception of dental midline deviation differences between orthodontically completely treated and untreated patients. Methods: This was a cross-sectional survey of 90 orthodontic patients, 49 completely treated patients who had completed orthodontic treatment and 41 untreated patients who had not started treatment. Patients were asked to complete a Google Form questionnaire for evaluating 12 intraoral smiling photos with midline deviation and a Likert scale. Bivariate statistical analysis with the Mann Whitney test was carried out to see differences in visual perceptions between two groups. Results: Completely treated patients perceive a 0-1 mm (LCN/L photos) midline deviation of the upper teeth as attractive, while untreated patients perceive a 0-2 mm (LCN photos) and 0-3 mm (L photos) deviation as attractive. The statistical analysis revealed a significant difference in patient perception between completely treated and untreated groups, with a p-value of 0.001 (p<0.05) and a mean score of 36.5 and 53.0, respectively. Conclusion: There are differences in visual perception between orthodontically completely treated and untreated patients. The group of completely treated patients is more sensitive to detecting a midline deviation of the upper teeth..Keywords : Upper dental midline deviation, visual perception, completely treated orthodontic patients, untreated orthodontic patients

Formative Assessment Practices, University Teachers and Students’ Perceptions

The present study aims to determine the major differences in student’s opinions towards formative assessment across universities. The study also wanted to understand the university teacher’s perception and their role in implementing the formative assessment in their classroom and to see the university teacher’s perception towards the impact of usefulness of formative assessment. The study used quantitative research design. Data was collected from four hundred students and one hundred teachers from four different universities of Lahore by using simple random sampling technique. An adapted form of survey tools were used to collect information from the study participants. The data was analyzed by using Descriptive analysis, Frequencies, t-test and one-way analysis of variance (ANOVA). Frequencies were used to examine the high and medium perceived statements by the teachers and students. The results reported statistically significant difference in perceptions of students among four universities of Lahore. The Study also presented university teachers perceptions regarding formative assessment. It is suggested that seminars and trainings be held for students and teachers in order to make them aware of assessment and evaluation skills.

THE ROLE OF GENDER IN RISK PERCEPTION AND RISK TOLERANCE FOR ENTREPENEURS

Entrepreneurship is often seen as a man's job. This is because women are considered more afraid of failure than men. Working as an entrepreneur is certainly not free from risks, so the purpose of this study was to look at differences in risk perception and risk tolerance based on gender. The sample of this research is 81 entrepreneurs. The method used in this study is the independent t test and ANOVA test. This study shows the results that there are significant differences in risk perception and risk tolerance based on entrepreneur gender. Other findings were also found in this study, where the higher the perception, the lower the tolerance for risk.

Undergraduates’ Level of Study as Determinant of Perception, Knowledge and Attitudes Towards Global Warming in Ekiti State, Nigeria

The study examined undergraduates’ level of study as determinant of perception, knowledge and attitude towards global warming among undergraduates in Ekiti State, Nigeria. The descriptive research survey design was adopted in this study. The population consisted of all undergraduates in all the Universities in Ekiti State. The sample for this study consisted of 600 undergraduates which were selected from the three universities in Ekiti State. The sample was selected through multistage sampling procedure. A questionnaire designed by the researcher tagged “Global Warming Questionnaire (GWQ)” was used to collect relevant data for the study. The face and content validity of the instrument was done by specialists in Social Studies and Tests and Measurement experts. The reliability of the instrument was ensured through test re-test method of reliability. The scores of the two tests were correlated using Pearson Product Moment Correlation Coefficient Analysis. The correlation coefficient of 0.82 was obtained which was good enough to make the instrument reliable. The research hypotheses generated were tested using inferential statistics. The study revealed that there was no significant difference in knowledge and perception of global warming among undergraduates based on level but there was significant difference between attitudes of undergraduates towards global warming based on level, It was recommended that curriculum planners and other education stakeholders should see to regular review of tertiary institutions curriculum by updating new developments on global warming into the curriculum for undergraduates to familiarize themselves with latest information concerning global warming.

Particularly, it aims to identify the demographic profile of the users and personnel in terms of age and ICT competence, determine the perceived level of effectiveness of Land Transportation Office portal among the users and personnel in terms of information quality, design and functions, reliability, security and privacy protection, system responsiveness, perceived usefulness, user satisfaction, and continuance intention. This research study utilized a descriptive – survey design. Total enumeration was applied to the personnel, while simple random sampling was used for the users. A self-constructed questionnaire was used as the research instrument, and the data collected was analyzed through simple linear regression analysis, frequency and percentage distribution, weighted mean, independent Ttest, and one-way analysis of variance. Based on the findings, the majority of respondents were between the ages of 16 and 25, and the majority had intermediate ICT competence. The study concluded that the LTO portal was highly effective in terms of information quality, design and functions, reliability, security and privacy protection, system responsiveness, perceived usefulness, user satisfaction, and continuance intention. However, there were significant differences in perceptions based on age and ICT competence, suggesting the need for targeted improvements in these areas. Establishment of a monitoring tool for the L TO portal is recommended for its continuous enhancement.

Construct validity of the physical activity neighborhood environment scale-Oman.

This study aims to examine the construct validity of Physical Activity Neighborhoods Environment Scales, Oman (PANES-O), and compare the subjective perceptions with objective measures in Muscat, the capital area of Oman. Walkability index scores using GIS maps were calculated for 35 study areas in Muscat based on which five low and 5 high walkable study areas were randomly selected. A community survey was then conducted in November 2020 in each study area using the 16-item PANES-O instrument to measure the participants' perception of neighborhood density, land use mix, infrastructure, safety, aesthetics, and street connectivity. Due to pandemic restrictions, a social media-based purposive sampling strategy was utilized to reach community-based networks and complete digital data collection. Significant differences between the low and high walkablehigh-walkable neighborhoods were observed for 2 of 3 macroenvironment subscales, density and land use. Respondents in high walkable neighborhoods perceived their areas as having more twin villas (P = 0.001) and apartment buildings (P < 0.001), greater access to destinations (like more shops, and places to go within walking distance; P < 0.001), easy access to public transport (P < 0.001), and more places to be active (P < 0.001); than their counterparts in low walkable neighborhoods. In terms of microenvironmental attributes, respondents in high walkablehigh-walkable neighborhoods perceived their areas to have better infrastructure, better aesthetic qualities, and better social environment than their counterparts in low walkablelow-walkable neighborhoods. Significant differences in perceptions across 12 of the 16-item PANES tool confirmed that 6 of the 7 subscales were significantly sensitive to built environment attributes between the low and high walkable study areas. Respondents in high walkable neighborhoods perceived their areas as having greater access to destinations (like more shops, places to go within walking distance; P ≤ 0.001), easy access to public transport (P ≤ 0.001), more places to be active (P ≤ 0.001), better infrastructure (like more sidewalks, facilities to bicycle; P ≤ 0.001), and better aesthetic qualities (P ≤ 0.001). PANES-O also was able to rate high walkable neighborhoods to be higher in residential density and land-use mix compared to the low walkable neighborhoods demonstrating its sensitivity to the GIS maps' objective measures. These results provide preliminary strong support for the construct validity of PANES-O, suggestingconfirming that it is a promising tool for assessing macroenvironmental perceptions related to physical activity in Oman. Further research using objective measures of microenvironments and device-based physical activity scores is needed to confirm the criterion validity of the 10 micro-environmental attributes of PANES-O using objective measures for the microenvironment. PANES-O could be used to generate and develop the needed evidence on the most appropriate approaches to improving the built environment to promote physical activity and urban planning in Omanthe country.

Human thermal physiological response of wearing personal protective equipment: An educational building semi-open space experimental investigation

With the outbreak and spread of the COVID-19 epidemic, HCWs are frequently required to wear personal protective equipment (PPE) for nucleic acid sample collection in semi-open transition spaces. Wearing PPE causes significant psychological and physical stress in HCWs. In this study, operative temperature (Top) and wet-bulb globe temperature (WBGT) were used to assess thermal conditions through field experiments, while multiple physiological parameters were measured in the subjects. The results indicated that the subjects showed statistically significant differences in thermal perception and physiological parameters with and without PPE. Using observed increases in heart rate (HR), auditory canal temperature (Tac), mean skin temperature (MST), and end-tidal CO2 pressure, subjects were shown to have an increased metabolic rate and heat storage while wearing PPE. Additionally, a decrease in oxygen concentration was also observed, and this decrease may be linked to fatigue and cognitive impairment. Moreover, HR, MST, and Tac showed a significant linear relationship, which increased with temperature and operative temperature, and the HR response was stronger with PPE than without PPE. The neutral, preferred, and acceptable temperatures were significantly lower with PPE than without PPE, and the deviations for neutral Top/WBGT were 9.5/7.1 °C and preferred Top/WBGT was 2.2/4.0 °C, respectively. Moreover, the upper limits of acceptable WBGT, 29.4 °C with PPE and 20.4 °C without PPE, differed significantly between the two phases. Furthermore, the recorded physiological parameter responses and thermal perception responses of the subjects while wearing PPE indicated that they were at risk of thermal stress. Overall, these results suggest that people who wear PPE should focus on their health and thermal stress. This study provides a reference for the development of strategies to counteract heat stress and improve thermal comfort.

Social media aids for business learning: A quantitative evaluation with the 5E instructional model.

Social media use is widely accepted in higher education, connecting students' learning with daily life. Considering the potential of social media to revolutionize the whole spectrum of teaching and learning, this study examines social media usage of business school students of different majors and their perception of social media as learning aids through a quantitative online survey guided by the 5E instructional model, with 423 valid responses from students majoring in accounting, finance, and economics. Results indicated that respondents perceived social media as influential in helping them access study-related information. It facilitated comprehensive learning, information access, information sharing, and student communication with instructors. Significant differences in perceptions of using social media as aids for business learning were found among students of different demographics, including gender, education level, and residence, but not quite for different majors. While various studies have examined the use of social media in education, scant studies focus on business school students under the lens of the 5E instructional model, especially Asians.

Young Adults' Electronic Cigarette Use and Perceptions of Risk.

In the United States, 18.6% of college students between 19-and 22-years old report e-cigarette use in the last 30 days. Information regarding e-cigarette use and perceptions in this age group may assist in understanding how to decrease initiation of e-cigarettes in a population that may otherwise not use nicotine. The purpose of this survey was to determine current e-cigarette use and how e-cigarette use history relates to a college student's perceptions of health risks associated with e-cigarettes. A 33-item questionnaire was sent to students at a Midwestern university in Fall 2018. Overall, 3754 students completed the questionnaire. More than half of the respondents (55.2%) had used e-cigarettes and 23.2% identified as current users of e-cigarettes. Current e-cigarette users were more likely to agree that e-cigarettes are a safe and effective option to quit smoking, while never users were more likely to disagree (safe P < .001, effective P < .001). Current users were less likely to agree that e-cigarettes may harm a person's overall health than never users (P < .001). Young adults continue to be frequent users of e-cigarettes. There are significant differences in perceptions of e-cigarettes associated with use history. Additional research is needed to see how perceptions and use of e-cigarettes have changed considering lung injury reports and increased regulations in the U.S.

Long-term neurocognitive outcomes in 204 single-suture craniosynostosis patients.

Craniosynostosis, which describes premature fusion of one or more cranial sutures, has been associated with a variety of neurocognitive deficits. We sought to explore the cognitive profiles of the various types of single-suture, non-syndromic craniosynostosis (NSC). A retrospective review of children 6-18 years old with surgically corrected NSC who underwent neurocognitive testing (Weschler Abbreviated Scale of Intelligence, Beery-Buktenica Developmental Test of Visuomotor Integration) from the years 2014-2022 was conducted. 204 patients completed neurocognitive testing (139 sagittal, 39 metopic, 22 unicoronal, 4 lambdoid suture). 110 (54%) of the cohort was male, and 150 (74%) were White. Mean IQ was 106.10±14.01 and mean age at surgery and testing were 9.0±12.2 months and 10.9±4.0 years, respectively. Sagittal synostosis was associated with higher scores than metopic synostosis, with significant differences in verbal IQ (109.42±15.76 vs 101.37±10.41), full-scale IQ (108.32±14.44 vs 100.05±11.76), visuomotor integration (101.62±13.64 vs 92.44±12.07), visual perception (103.81±12.42 vs 95.87±11.23), and motor coordination (90.45±15.60 vs 84.21±15.44). Sagittal synostosis was associated with significantly higher scores for visuomotor integration (101.62±13.64 vs 94.95±10.24) and visual perception (103.81±12.42 vs 94.82±12.75) than unicoronal synostosis. Compared to patients with sagittal synostosis, patients with metopic synostosis exhibited lower scores in verbal IQ, full-scale IQ, visuomotor integration, visual perception, and motor control after surgical correction. Despite surgical correction for premature metopic suture fusion, the effect on the adjacent frontal lobe and white matter connections to other regions of the brain may have a lasting functional impact. Patients with unicoronal synostosis exhibited lower visuomotor integration and visual perception scores.

Differences in perceptions of capability, autonomy, and expectations between residents and surgical team members in executing EPAs in Ethiopian medical education

BackgroundEntrustable Professional Activities (EPAs) are units of professional practice that are defined as tasks or responsibilities that are entrusted to an unsupervised execution by a trainee. In 2021, a framework of 29 EPAs was developed for surgical residency training programs in Ethiopia, with the goal of residents being able to perform independently by the time they graduate. However, studies show that surgical residents lack confidence and are unable to execute EPAs autonomously upon graduation, and concerns have been raised about graduate competencies in EPA execution. The goal of this research is to assess how surgical team members judge/perceive residents' performance in executing these EPAs autonomously at the time of graduation and how residents rate their own capability and autonomy in executing EPAs in order to systematically introduce and implement EPAs in Ethiopian medical education MethodsA survey was conducted in the Departments of Surgery at four residency training institutions in Ethiopia. All eligible surgical team members and final-year general surgery residents were invited to participate. Surgical team members were asked to rate the observed performance of a group of graduating surgical residents in each of the 29 EPAs, and residents were asked to rate their own capability in executing EPAs. The analysis focused on variations in performance ratings between surgical team members and residents, as well as across surgical team members. ResultsA total of 125 surgical team members and 49 residents participated in this study. Residents rate their competence in performing these EPAs higher than surgical team members, mean 4.2 (SD = 0.63) vs. 3.7 (SD = 0.9). A statistically significant difference in perceptions of capability, autonomy, and expectations in executing EPAs was observed between the two groups of study (p = 0.03, CI: 0.51–0.95), as well as within surgical team members (p < 0.001). ConclusionsDifferences in perceptions of capability, autonomy, and expectations between residents and surgical team members, as well as within faculty members, were seen in executing EPAs. There were concerns about graduate surgical residents' competence to execute EPAs autonomously at the time of graduation. Surgical team members perceived that a set of graduating surgical residents are not yet safe to perform these EPAs independently (without supervision) and still requires distant supervision.

Design of Flipped Lessons in the Classroom and Opinions of Teachers with Different Degrees of Experience

The flipped classroom approach has gained significant popularity recently due to its ability to facilitate active learning and leverage technology to enhance student's learning habits. Previous research has explored the benefits and drawbacks of this approach, highlighting its potential to improve student engagement, motivation, and achievement. However, despite the growing interest in flipped classroom approach, more is needed to know about teachers' perceptions of this model and how these perceptions may vary based on years of experience.The current study aims to address this gap in the literature by examining 73 Kindergarten through 12th-grade teachers' perceptions of flipped classroom approach and identifying differences in these perceptions based on years of experience. To this end, the study utilized a survey instrument developed by Gough et al. (2017) to gather data on teachers' attitudes toward flipped classroom approach across five domains, including instructional practices, student considerations, technology use, communication, and practice.By analyzing the survey data, the study identified significant differences in teachers' perceptions of flipped classroom approach based on years of experience. Specifically, teachers with 0-3, 3-5, and more than 5 years of teaching experience had different judgments in instructional practices and student considerations. These findings suggest that teachers' perceptions of flipped classroom approach may be influenced by their experience level and that targeted professional development and training may be necessary to support teachers in adopting this approach effectively.Overall, this study contributes to the literature on flipped classroom approach by shedding light on teachers' perceptions of this model and how these perceptions vary based on years of experience. The findings provide insights into the elements that could enhance the effectiveness of flipped classroom approach, such as differentiation, more videos for specific learners, communication with all parties, and practice. The practical implications of these findings for K12 settings are discussed in the subsequent sections of this article.

Effect of musical instrumentation on perception of reverberation in simulated listening environments

The reverberance of a performance venue is often characterized by an important metric, reverberation time. In order for architects, acousticians, and performers to better understand the value of knowing and predicting the reverberation time in different spaces, the just-noticeable-difference (JND) is often cited. The established JND for reverberation time is approximately 5% of the reference reverberation, noted in the standard ISO 3382-1. This value was determined using impulsive sound, meaning it may not provide a complete picture for applications related to music. This study aimed to evaluate several elements of musical performance that may alter the perception of reverberation in a simulated listening environment. Primarily, the effect of instrumentation was investigated, including the use of solo, small ensemble, full orchestra, and vocal recordings for comparison. Results were generated using test participants listening to multiple soundfields and providing subjective evaluation. Reverberant soundfields were created in an anechoic listening environment and auralizations were produced using ODEON room acoustics software. Results indicated statistically significant mean differences in reverberation perception between musical instrumentation groups used during experiments. [Work supported by The Paul S.

Bibliometric Analysis of Research Topics on Fire Safety

Various studies have been conducted to minimize property damage and casualties caused by fire accidents, which occur over 40,000 times annually on average. The research papers published in the Fire Science and Engineering journal indexed in the Korea Citation Index and the Fire Technology journal indexed in the Science Citation Index Expanded databases over the last 10 years were analyzed utilizing text-mining techniques. Similar research papers published these two journals were explored and significant differences in perceptions were identified. Recently, the proportion of studies on “Wild-Urban-Interface (WUI) fire” and “Battery fire” published in the Fire Technology journal has increased; however, “Firefighter organization” related research papers are being actively published in the Fire Science and Engineering journal. A quantitative analysis of the studies on fire incidents can provide significant information on developing new policies essential to reducing fire damage.

The Disparity Between Urban andRural Areas in Citizen Satisfaction with Local Public Services

The disparities in access to public assistances between rural and urban areas are analyzed in this study, corresponding to the intensity in which the constructs are related to expected quality, perceived quality and perceived value as influential factors in citizen satisfaction and loyalty. In Guayaquil, a survey is carried out at the household level, 428 valid questionnaires are obtained in the rural area of Tenguel and 521 Valid questionnaires in the urban area of Tarqui, applyingto the American Customer Satisfaction Index (ACSI). The research used a Structural Equation model (SEM) to evaluate the hypotheses raised, if they observe significant differences in citizen perception between inhabitants of urban and rural areas about the quality of community services, this as a determining cause in the level of citizen satisfaction and loyalty to choose their municipal authorities. The multigroup analysis allowed to identify inequalities in the observation of the quality of municipal or local communityassistances between rural and urban areas; the findings are considered to local public administrators for the design of public policy aimed at improving levels of citizen satisfaction and loyalty.

If there are too many reviews, it will take a lot of time and they will start to be biased. Sentiment classification tries to solve this problem by putting user reviews into groups based on whether they are positive, negative, or neutral. The dataset comes from Drone Emprit Academic. It is made up of tweets with the words "online learning method" in them, with as many as 4887 data crawled from them. Information Gain and adaboost on the C4.5 (FS+C4.5) method are used in the feature selection method. We use feature options to get rid of bias and improve accuracy. The results of the experiments will be compared to other algorithms like C4.5 and random forest. Based on the results, the accuracy of the two standard decision tree models (C4.5 and random forest) went up from 48.21% and 50.35% to 94.47 %. The value of how accurate it was went up by 44 percent. The FS+C4.5 model, on the other hand, has an RMSE of 0.204 and a correlation of 0.944. So, adding the feature selection technique to the sentiment analysis of bold learning education can make the C4.5 algorithm even more accurate.

Kultura a prawo w społeczeństwie pluralistycznym

The article discusses the problem of the relations between culture and law in a modern pluralistic society, where exist the significant ideological differences in perception of the fundamental human values. The positive law should serve the attainment of these values. At the beginning the Author takes a personalistic stance on a culture expressed at the Second Vatican Council, that “man comes to a true and full humanity only through culture, that is through the cultivation of the goods and values of nature” (Gaudium et spes, n. 53). In order to get answer to the above question – in Author’s opinion – the following problems should be considered: what is law, what are values, in particular, what are the Christian values and what is their relation towards the positive law provided by the State bodies. In conclusion, the Author indicated a dramatic cultural conflict in the legal systems of the Member State of the European Union, as a consequence of forcing by the positive law established by the bodies of the European Union the patterns of behavior, which are contrary to the Christian system of the universal ethical values, rooted in the Christian culture of the European nations.
