영아기 자녀 어머니의 공감능력이 어머니-교사 협력에 미치는 영향

Objectives The purpose of this study is to find out how the empathy ability of mothers of children in infancy affects mother-teacher cooperation and to verify the mediating effect of parenting competency that affects the causal relationship between these two variables.
 Methods An electronic survey was conducted on 284 mothers of infant children attending daycare centers in the Gyeonggi-do area. The collected data were subjected to reliability analysis, frequency analysis, descriptive statistical analysis, correlation analysis, and multiple regression analysis to verify mediation effects using the SPSS 29.0 program, and Sobel-test was performed to verify significance.
 Results First, the relationships between mothers' empathy and parenting capabilities and mother-teacher cooperation in infancy showed a positive correlation. Second, a partial mediating effect of parenting competency was found in the effect of the mother's empathy ability on mother-teacher cooperation during infancy.
 Conclusions This study consistently shows that mother-teacher cooperation plays an important role in the development of infants, but research on the characteristics of parents necessary to promote this is relatively insufficient. In this situation, the empathic ability of mothers of children in infancy is influenced by teachers. The significance of the study is that it was proven to be a parental variable that has a significant direct and indirect effect on cooperation with parents. Based on this study, it is expected that parent education programs will be activated to improve parents' empathy and strengthen their parenting capabilities.

Voxel-wise body composition analysis using image registration of a three-slice CT imaging protocol: methodology and proof-of-concept studies

BackgroundComputed tomography (CT) is an imaging modality commonly used for studies of internal body structures and very useful for detailed studies of body composition. The aim of this study was to develop and evaluate a fully automatic image registration framework for inter-subject CT slice registration. The aim was also to use the results, in a set of proof-of-concept studies, for voxel-wise statistical body composition analysis (Imiomics) of correlations between imaging and non-imaging data.MethodsThe current study utilized three single-slice CT images of the liver, abdomen, and thigh from two large cohort studies, SCAPIS and IGT. The image registration method developed and evaluated used both CT images together with image-derived tissue and organ segmentation masks. To evaluate the performance of the registration method, a set of baseline 3-single-slice CT images (from 2780 subjects including 8285 slices) from the SCAPIS and IGT cohorts were registered. Vector magnitude and intensity magnitude error indicating inverse consistency were used for evaluation. Image registration results were further used for voxel-wise analysis of associations between the CT images (as represented by tissue volume from Hounsfield unit and Jacobian determinant) and various explicit measurements of various tissues, fat depots, and organs collected in both cohort studies.ResultsOur findings demonstrated that the key organs and anatomical structures were registered appropriately. The evaluation parameters of inverse consistency, such as vector magnitude and intensity magnitude error, were on average less than 3 mm and 50 Hounsfield units. The registration followed by Imiomics analysis enabled the examination of associations between various explicit measurements (liver, spleen, abdominal muscle, visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), thigh SAT, intermuscular adipose tissue (IMAT), and thigh muscle) and the voxel-wise image information.ConclusionThe developed and evaluated framework allows accurate image registrations of the collected three single-slice CT images and enables detailed voxel-wise studies of associations between body composition and associated diseases and risk factors.

Statistical Analysis of Ionospheric Correlation for Shortwave System

AbstractStatistical analysis of the temporal and spatial variations in the ionosphere is necessary to improve the shortwave system. Based on the standardized Euclidean distance algorithm, multisource ionospheric assimilation data, International GNSS Service vertical total electron content data, and ionosonde data are used to statistically analyze the ionospheric correlation distance, and the variation of ionospheric correlation distances with local times, magnetic latitudes, and seasons are obtained. The statistical analysis results show that the zonal ionospheric correlation distance presents minima in the equatorial ionospheric anomaly crest regions. Additionally, the meridional correlation distance in middle magnetic latitudes is greater than that in other regions. The zonal ionospheric correlation distance presents obvious local‐time variability. The variation trends of the meridional and zonal correlation distance during spring and autumn are similar. The patterns of the ionospheric correlation range variation with local times, magnetic latitudes, and seasons can be used to select the optimal locations or spacing for ionosonde stations, shortwave multi‐station systems, and shortwave radio beacons.

The amount of drunk days and its relationships with other characteristics of alcoholic behavior of the respondents

Introduction Alcohol abuse is a multifaceted problem. Its harmful effects on the individual have been more studied. Less studied is the influence of a drinking person on his microsocial environment. Having an abusing person in his space makes it interesting to study the influence of some quantitative and qualitative indicators of his alcohol consumption on the microsocial environment.Objectives1532 people were examined during 2018-2022, who belonged to three comparison groups: patients with alcohol dependence (AD) (401 people); healthy relatives of AD patients (725 people); representatives of the general population comparable with the representatives of the first two age groups (406 people).MethodsThe main research instruments were the questionnaire of the international research consortium “GENAHTO” (Gender, Alcohol, and Harms to Others), as well as the Alcohol Use Disorders Identification Test (AUDIT). The obtained data were processed by methods of mathematical statistics (variance, correlation and regression analysis).Results An algorithm for regression analysis in conditions of high dispersion of the initial data has been developed. Using this algorithm, it was shown that the regression dependence of the main characteristics of alcohol behavior on the frequency of DD is non-linear, while for typical and maximum doses of alcohol it is optimally described by polynomials of the second degree, and for the severity of disorders due to alcohol use (AU), the time spent on AU, as well as self-assessment of the negative impact of AU by respondents on their environment - by polynomials of the third degree. It was found that for men (on average) to reach the border of risky-dangerous AU (according to the criteria of the AUDIT test), a lower frequency of DD is sufficient than for women, which indicates a greater vulnerability of men (compared to women) to the formation of disorders due to AU.ConclusionsIt was established that for men (on average) to reach the limit of risky and dangerous (according to the criteria of the AUDIT test), a lower frequency (2-3 times a week) is enough than for women (3-4 times a week), which once again indicates greater vulnerability of men (compared to women) to the formation of due to psychological problems and mental disorders.Disclosure of InterestNone Declared

Correlation between end-weight principle and adjective clauses in English: Q1 SCOPUS applied linguistics articles and Thai EFL learners’ essays

The researcher in this study applied the notions of quantitative method, theoretical linguistics and applied linguistics to examine the correlation between the linguistic theory of end-weight principle and English adjective clauses in Q1-SCOPUS applied linguistics articles and Thai EFL learners’ descriptive essays. The significance of this study is that structure and use in writing should be learned simultaneously. This current study also innovatively supports Thai EFL learners to examine their linguistic competence in structuring information in their English writing. The data collection in this study was divided into two datasets. The first dataset was 20 Q1-SCOPUS applied linguistics articles published between 2022 and 2024. Approximately 200,000 words provided 117 sentences containing adjective clauses in the final position or VP-postmodifiers. On the other hand, the second dataset was 67 descriptive essays written by Thai EFL high-school learners from both public schools and private schools under the supervision of the Ministry of Education, Thailand. The original theory of the end-weight principle proposed by Quirk et al. (1972) is followed in this study. The syntactic structure of adjective clauses follows Radford (2009) who analyzed adjective clauses as complementizer phrases (CP). The inferential statistical analysis of correlation follows SPSS 29. The results showed that there was a statistically significant relationship between the datasets of applied linguistics articles and EFL learners’ descriptive essays where the p-values were reported at 0.01 and 0.02, respectively. Not only do these statistical relationships show that English is an end-weight language, but also Thai EFL learners can follow the norm accurately. This is due to the positive effect of the mother tongue interference since the Thai language is an end-weight language. The pedagogical implication of the study to EFL learners is that information structures should be contributed to grammar classes. For future studies, it is recommended to test the hypothesis of the end-weight principle with reduced adjective clauses in the medial position of sentences.

Abstract 2529: Comparison of small cell lung cancer transcriptional factor expression by immunohistochemistry, multiplex immunofluorescence, and a targeted RNA expression panel

Abstract Recent studies have identified distinct molecular subtypes of small cell lung cancer (SCLC) (SCLC-A, SCLC-N, SCLC-P, and SCLC-Y) based on ASCL1, NEUROD1, POU2F3, and YAP1 expression. In this study, we investigated the correlation between immunohistochemistry (IHC), multiplex immunofluorescence (mIF), and RNA Salah Targeted Expression Panel (RNA STEP) for ASCL1, NEUROD1, POU2F3, and YAP1 in formalin-fixed-paraffin-embedded (FFPE) samples from 14 SCLC samples collected under an IRB-approved protocol (MCC19163). For the mIF evaluation, FFPE samples were immunostained using the AKOYA Biosciences OPAL TM 7-Color Automation IHC kit on the BOND RX autostainer. For RNA STEP, nanoString nCounter TagSet chemistry was used to measure gene expression levels of test FFPE samples relative to a reference pooled human normal mRNA control. All three methods demonstrated significant correlation for ASCL1 levels (Table 1). IHC and RNA STEP NEUROD1 results exhibited significant correlation. However, mIF NEUROD1 results did not correlate with the results of other methods likely due to non-specific positivity of the NEUROD1 mIF antibody. No strong correlation was observed between any of the methods for POU2F3 and YAP1. Only 2 of the 14 samples displayed positive POU2F3 protein expression by IHC; one of these also had elevated POU2F3 expression by RNA STEP. Importantly, the sample with the highest POU2F3 protein expression by IHC also had the highest values by mIF and RNA STEP. All samples were negative for YAP1 by IHC and RNA STEP. Notably, ASCL1 staining was primarily observed in CD56+ POU2F3- cells by mIF. These findings highlight the reliability and utility of IHC and RNA STEP in assessing transcriptional factors in SCLC. Also, mIF presents an innovative method for the simultaneous analysis of multiple markers using a single tissue section, enabling the concurrent detection of multiple markers within individual cells.

Objectives In this study, we tested the mediating effect of belief in a just world in the relationship between young part-time workers' experiences of discrimination and career indecision.
 Methods An online survey was conducted targeting young people aged 15 to 34 with part-time work experience. The final 259 copies were used for statistical analysis. Descriptive statistical analysis, reliability analysis, correlation analysis, and regression analysis were performed using the SPSS 23.0 statistical program. And to verify the mediation effect, bootstrapping was performed to verify statistical significance.
 Results The average experience of discrimination was 3.06, the average career indecision was 2.32, and the average belief in a fair world was 3.77. and the average belief in a just world was 3.77. There was a positive correlation that the more discrimination experiences young part-time workers had, the higher their career indecision. There was a negative correlation between the experience of discrimination and overall belief in a just world, distributive justice belief, and procedural justice belief. It was confirmed that belief in a just world had a full mediating effect on the impact of youth discrimination experiences on career indecision. In addition, the partial mediating effect of distributive justice belief and the full mediating effect of procedural justice belief, which are subvariables of belief in a just world, were confirmed.
 Conclusions This study emphasizes the need to consider the cognitive variable of belief in a just world in the relationship between young part-time workers' experiences of discrimination and career indecision. Based on this, we laid the foundation to reduce the career indecision of young part-time workers who are experiencing discrimination and provide education and counseling opportunities to help young people enter the labor market.

Predicting the development of vulvar lichen sclerosus

Relevance. The issue of timely diagnosis and treatment of vulvar lichen sclerosus has become especially acute in recent years due to the “rejuvenation” of the disease and the risk of its malignancy. In this regard, it is urgent to search for effective methods for predicting and early detection of the disease. The aim of the study - to develop amodel for predicting vulvar lichen sclerosus based on established clinical and anamnestic risk factors. Materials and Methods. The prospective case-control study included 404 women aged 20 to 70 years, of which 344 were patients with vulvar lichen sclerosus and 60 were women without vulvar diseases. At the first stage, acomparative statistical correlation analysis of the clinical and anamnestic data of the subjects was carried out using the Spearman correlation coefficient (R0.15), Chi-square tests, Phi and Cramer statistics, the Mann-­Whitney U test and the Student t test (p 0.05). The data obtained were used to develop aneural network model for predicting vulvar lichen sclerosus in the second stage of the study. Results and Discussion. Based on established reliably significant (p0.05) obstetric-­gynecological, somatic, infectious, hygienic and household factors influencing the risk of developing vulvar lichen sclerosus (Rindicator - from 0.16 to 0.38 confirms the statistical significance of correlations), aneural network model for predicting vulvar lichen sclerosus was developed (the percentage of correct classification on the test sample is the maximum possible value - 100%) and acomputer program was written that automates the procedure for predicting the disease. Conclusion. The neural network model for predicting the disease, developed on the basis of reliably (p0.05) significant risk factors for vulvar lichen sclerosus, has high prognostic properties, and acomputer program written on its basis allows the doctor in amatter of minutes to identify the patient at risk for the development of vulvar lichen sclerosus and give she needs preventive recommendations aimed at preventing or early detection of the disease.

The relationship between self-consciousness and depression in college students: the chain mediating effect of meaning life and self-efficacy, with the moderating effect of social support

BackgroundThis study aimed to investigate the impact of self-consciousness on depression of college students, and mainly focus on confirming the mediator role of life meaningful and self-efficacy, as well as the moderator role of social support.MethodsIn the present study, convenient sampling method was adopted, 583 college students were recruited from Harbin city and Wenzhou city in China. All students were assessed using self-assessment scales, including self-consciousness scale, life meaningful scale, self-efficacy scale, social support scale, and self-rating depression scale. Descriptive statistical analysis and correlation analysis, structural equation model analysis were conducted by SPSS 25.0 and M-plus.ResultsResults showed that self-consciousness was negatively related to depression, life meaningful and self-efficacy partially mediated the relation between self-consciousness and depression. Moderated mediation analysis further indicated that the relation between self-efficacy and depression were moderated bu social support. Compare with college students who had high social support, depression in those with low social support was more susceptible to the effect of self-efficacy.ConclusionThese findings imply that college students with low levels of self-consciousness are more easy to be depressive, enhancing their sense of life meaning and self-efficacy can effectively alleviate depression, and college student with high social support can benefit more from self-efficacy. Therefore we should pay more attention to the mental health problems of low levels self-consciousness college students in university.

Impact of feeding native Caatinga pasture on the rumen histomorphometry of sheep raised in semi-extensive management.

In the northeastern region of Brazil, sheep and goat farming, encompassing around 20 million animals, is predominantly a subsistence activity. Forage quality plays a crucial role in animal productivity, posing a complex interplay between plant and animal aspects. The Caatinga biome, vital for livestock in the region, serves as a significant source for animal diet through pastures. This study aimed to conduct a histomorphometric evaluation of sheep rumens in a semi-extensive system, comparing those feeding on native Caatinga pastures to those on cultivated pastures. Histological processing followed standard protocols, with morphometry focusing on six viable rumen papillae and the submucosa and muscular layer thickness. Statistical correlation analysis revealed morphological differences in papillae across various rumen regions. Morphometric data indicated no significant difference in papillae area between the groups, with average values in Group A surpassing those in Group B, except for width. This study establishes a morphological and morphometric pattern for rumen regions linked to diet types-native or cultivated. The findings not only enhance understanding of the dietary foundation in the Caatinga's extensive system, but also contribute valuable insights for formulating nutritional strategies to enhance sheep production in the region. This research sheds light on the intricacies of forage-based animal nutrition, particularly in semi-extensive systems, offering a foundation for future studies and practices to optimise livestock management in the northeastern Brazilian context.

Tumor-to-stroma cd8+ t cells ratio combined with cancer-associated fibroblasts: an innovative approach to predicting lymph node metastases of cervical cancer

PurposePrecise identification of lymph node metastases is vital for the management of cervical cancer. However, the existing diagnostic methods for lymph node metastases have certain drawbacks. In this study, we aim to explore the expression of cancer-associated fibroblasts (CAFs) and tumor-to-stroma CD8+ T cells ratio (CD8+ T cells T:S ratio) and its association with lymph node metastases of cervical cancer.MethodsHundred and ten cervical cancer tissues and 39 biopsy tissues from patients were investigated immunocytochemically for the expression of CAFs and CD8+ T cells. The statistical correlation analysis was carried out using the SPSS system.ResultsA strong and statistically significant negative correlation (r= − 0.690; P < 0.001) was observed between CAF density and CD8+ T cells T:S ratio. Not only were CAFs density and CD8+ T cells T:S ratio correlated with lymph node metastases respectively (P < 0.001), but the combination of them also significantly correlated with lymph node metastases (P < 0.001). Then, we constructed the combined diagnosis model (Logit (P) = − 4.446 + 0.300 × CAFs + 0.752 × CD8+ T cells T:S Ratio) of cervical cancer lymph node metastases. ROC curves analysis showed that the ROC curves areas for CAFs, CD8+ T cells T:S ratio, and a combination of both are 0.879, 0.747, and 0.951. Then, the prediction model was verified by biopsy specimens and consistent results were obtained.ConclusionsThe combination of CAF density and CD8+ T cells T:S ratio has a significant predictive value for lymph node metastases in patients with cervical cancer.

기업의 교육훈련 투자와 신입근로자의 조기퇴사율 간의 관계

Objectives This study aimed to analyze the relationship between variables at the corporate and employee levels by utilizing data from the Human Capital Corporate Panel Survey II (HCCP II) conducted by the Korean Research Institute for Vocational Education and Training in 2021. In order to do so, the study set the corporate training and development investment has an impact on early resignation rate of new employees, and to confirm whether job skill enhancement and job satisfaction have a partial mediating effect in the process.&#x0D; Methods To do this, an analysis was conducted on data obtained from a survey conducted on 854 participants who responded to the 2021 2nd headquarters and employee survey of the Human Capital Corporate Panel (HCCP II) by the Korea Research Institute for Vocational Education and Training. To examine the relationships and distributions among various variables, basic statistical analysis and correlation analysis were conducted using STATA 17 version. Additionally, validity checks were performed during the aggregation process at the organizational level, utilizing Intra-Class Correlation (ICC) and rwg indices. For validation purposes, partial mediation model analysis and significance testing were carried out using the bootstrap analysis method. Corporate training and development investment was assumed as an independent variable, early resignation rate of new employ-ees was assumed as a dependent variable, job skill enhancement and job satisfaction as mediating variables.&#x0D; Results According to the analysis, corporate training and development investment had a negative effect on early resignation rate of new employees. Second, the corporate training and development investment was found to have a positive impact on reducing the early resignation rate of new employees through the job skill enhancement. Third, the corporate training and development investment was confirmed to have a positive impact on reducing the early resignation rate of new employees through increased job satisfaction. The results of this study indicate the need for corporate training and development investment to reduce the early resignation rate of new employees. Furthermore, it was observed that as job skill enhancement and job satisfaction of new em-ployees increase through training and development, the early resignation rate decreases.&#x0D; Conclusions The results indicating that the corporate training and development investment has a positive impact on reducing the early resignation rate of new employees are significant in confirming the effectiveness and necessity of training and development. New employees can enhance their proficiency in job-related skills through education and training. This improve-ment has a positive impact on the job satisfaction of new employees. Moreover, perceiving the organization's investment in edu-cation and training as an investment in and interest in oneself, new employees may develop an increased desire to stay with the organization. To enhance job skill and job satisfaction among new employees and reduce early resignation rate, companies should consider investing in corporate training and development. Furthermore, the significance lies in verifying and confirming the partial mediating effect of job skill enhancement and job satisfaction between the corporate training and development in-vestment and the reduction of the early resignation rate of new employees. This contribution reveals the detailed process through which the effects of corporate training and development investment in reducing the early resignation rate, particularly by examining whether job skill enhancement and job satisfaction mediate this effect. Moreover, the study contributes academ-ically and practically by highlighting the role of job skill enhancement and job satisfaction as intermediate variables in the process where the effects of the corporate training and development investment are observed.

Digital assessment of supracrestal tissue attachment and its correlation with dentogingival components.

The aim of this study is to measure, in vivo, the supracrestal tissue attachment dimensions (STADs) by means of a noninvasive digital method and to investigate the association between STADs and gingival thickness (GT), tooth position, tooth length, tooth width, keratinized tissue width (KTW), buccal bone thickness (BBT), and bone crest (BC) level. Nineteen periodontally healthy subjects who previously received full mouth periodontal charting, cone beam computed tomography, and intraoral scan for the purpose of implant planning were included in the study. A digital imaging software was used for the superimposition of Digital Imaging and Communications in Medicine and stereolithography files, along with hard and soft tissue measurements. Pearson's correlation and ANOVA statistical analyses were used to investigate potential trends between STADs and other dentogingival components. A total of 203 teeth were assessed, with an average STADs of 2.05mm (±0.99mm). STADs were larger in mandibular than maxillary teeth (p-value <0.001) and decreased from anterior to posterior teeth. STADs exhibited an inverse relationship with BBTs and GTs (p-value <0.001) and the KTW (p-value=0.05). Positive correlations were found between GT and BBT (p-value <0.001), whereas both were negatively correlated with the distance between the cementoenamel junction and BC (p-values 0.019 and 0.006, respectively) and positively correlated with KTW (p-value <0.001). This study highlighted the dynamic nature of STA relative to tooth position. Additionally, it explored the intricate relationships of STADs with various dentogingival components. To the best of the authors' knowledge, this study represents the first application of CBCTs, intraoral scans, and clinical probe depths for noninvasive supracrestal tissue attachment measurements. This study advocates for a personalized assessment of supracrestal attachments, incorporating tooth position and other dentogingival components. The study emphasizes the importance for practitioners to consider the specific patient gingival phenotypes during restorative or surgical planning to avoid adverse outcomes.

Hydrochemical Characteristics and Genesis Mechanism of Groundwater in the Dry Period in the Zhangjiakou Area

In order to better support the construction of the capital water conservation functional area and ecological environment support area， research on the chemical characteristics of groundwater and its formation mechanism in the dry period in the Zhangjiakou area can provide a great reference for the rational development and utilization of groundwater resources. A total of 41 groups of groundwater samples were collected， and the hydrochemical types， composition characteristics， and control factors of groundwater in the study area were analyzed by using the combined method of descriptive statistical analysis， Piper triplot， correlation analysis， Gibbs plot， and ion ratio. The results showed that the groundwater in the study area was weakly alkaline， with the total hardness and ρ（TDS） ranging from 105.00 mg·L-1 to 1 433.00 mg·L-1 and 137.00 mg·L-1 to 2 286.00 mg·L-1， respectively. The total hardness and TDS mass concentrations of groundwater in the Bashang area were higher than those in the Baxia area. HCO3- and Na+ were the main dominant anions and cations in the groundwater in the study area. The highest overstandard rate of the main components in groundwater was that of total hardness （36.59%）. The overstandard rate and maximum excess multiple of each component in groundwater in the Bashang area were greater than those in the Baxia area. HCO3-Ca·Mg·Na was the main type of groundwater hydrochemistry in the study area， and there was little difference between the Bashang area and the Baxia area. SO42-， Cl-， HCO3-， Na+， and Mg2+ contributed the most to TDS. The chemical characteristics of groundwater were affected by weathering and filtration of rock minerals such as salt rock， albite， and dolomite； cation exchange； and human activities. Evaporative crystallization and atmospheric precipitation contributed to a small part of the main ion source of groundwater in the area. The effect of human activities on groundwater in the Bashang area was greater than that in the Baxia area， and NO3- mainly originated from agricultural activities.
