This study was undertaken to investigate the inheritance in craniofacial complex among Korean familial members. The subjects were 160 lateral cephalometric radiographs from 45 families. Standard product-moment correlation coefficients(r) were calculated for the measurements between the familial pairings. Further, coefficients of $determination(r^2)$ were calculated and multiple regression analyses were performed to assess the use of parents' record for predicting an offspring's craniofacial features. The following results were obtained. 1. First-degree relatives had a high level of significant correlations which were compatible with a polygenic theory of inheritance than those of non-relatives. 2. Mother-daughter pair had the highest significant correlations, then mother-son and father-son pairs, and, finally, father-daughter pair had the lowest significant correlations. 3. The genetic influence was higher in anterior cranial base length and genial angle. In contrast, the environmental influence was higher in posterior border of ramus, maxillary ant. teeth, maxillary & mandibular apical bases and Gla-P. occ. 4. The predictability of offspring's cranio-facial growth could be improved by using multiple measurements from both parents than those from father or mother only.

The purpose of this study was to examine the role of children's characteristics, family environment and child care quality in socio-emotional development of children among dual-worker families. The sample consisted of 138 children aged 5-7 and their parents. Descriptive statistics, t-tests, correlation analysis, one-way ANOVAs, and stepwise regression were used to analyze data. Results showed that there were significant sex differences in children's temperament and popularity. Mother's marital satisfaction had a negative correlation with peer rejection. Low maternal role conflict and child's age had effects on children's self-perception. Moreover, sex and age of the child, mothers' responsive parenting, number of teachers in the classroom were significant predictors for children's peer rejection.

The present study investigated differences in children's school achievement and emotional and social development by type of after-school care: self-care and mother-care. It also examined relationships between children's developmental outcomes and ecological variables, including individual, familial, and environmental variables by care methods. The data of 330 mother-care and 161 self-care children was provided by teachers, mothers, and the children themselves. The analyses of the data were conducted by t-test, correlation, and regression. Findings were that mother-care children had higher scores in grades, school adjustment and teacher relationship and lower depression and withdrawn behaviors than self-care children; after-school activities and peer support predicted the developmental outcomes of mother-care children; gender, autonomous ability, and behavior control predicted the development of self-care children.

This study was attempted to find out the familial influence on adolescent's civism. For this purpost, data were obtained from 177 male and female freshmen and sophomores at univerwities in Seoul and Inchon and analyzed with correlation, t-test, ANOVA, Scheff test and stepwise multiple regression. The major findings were as follows: 1) The level of parents' education and family living had no significant relations to adolescent's civism. 2) Parents and adolescent interaction had indirect influence on adolescent's civism through parents' morality and discipline. 3) Parents' morality, materialistic value orientation and discipline about community norms had influences on adolescent's civism in descending order. These independent variables explained 20.5% of the total variance.

The objective of this study was to develop a scale to measure stress in infertile couples and to test its reliability and validity. Prior to item generation, a basic decision was made to conceptualize stress in infertile couples as including two dimensions and four subdimensions. The dimensions were, intrapersonal stress including cognitive and affective stress, and interpersonal stress including marital and social stress. Initially 95 items were generated from the inter-view data of 31 primary or secondary infertile women and from a literature review. These items were analyzed through the Index of Content Validity(CVI) and 69 items were selected which met 70% or more of the CVI. This preliminary Infertility Stress Scale were analyzed for reliability and construct validity. Item analysis and factor analysis were applied for construct validity. Forty items were selected through item analysis. This procedure was based on the inter-item correlation matrix, a corrected average inter-item correlation coefficient(.30~.70), a corrected item to total correlation coefficient (.03 or more) and information about the alpha estimate if this item was dropped from the scale. The result of the initial factor analysis including varimax rotation produced eight factors. Five items deleted because of factor complexity(indiscriminate factor loadings). The secondary factor analysis including varimax rotation produced seven factors that coincided with the conceptual framework posed for the scale developed. The seven factors were labeled as ‘meaning of children’,‘worthiness’,‘tenacious linking’,‘marital satisfaction’,‘sexual satisfaction’,‘familial adjustment’ and ‘social adjustment’. The alpha coefficient relating to internal consistency was .93 for reliability The results of this study suggest that the measurement derived from the Infertility Stress Scale is useful in assessing the stress of infertile couples.

Purpose: This study explored the degree of internet addiction and its influencing factors in lower grade elementary school children in rural areas. Methods: Subjects included 1,137 elementary school children. A structured questionnaire consisting of questions internet addiction, family function and school life satisfaction was used for data collection. Descriptive statistics, ${\chi}^2$-test, ANOVA and Correlation and Regression were performed using a SPSS program. Results: Among the subjects, 85.8% were regular users, 8.1% were potential risk users, and 6.1% were high-risk users. Career of internet use, daily internet access time, the number of conversations per week, the number of times spent eating out and traveling with parents within the last month and activities with friends, and satisfaction on school life differed significantly according to the degree of internet addiction. Finally, among the factors studied, daily internet access time, conversations within family, activities with friends and school life satisfaction in children in early elementary school was 20.7% of the explanatory power of the subjects' degree of internet addiction, collectively. Conclusion: Use of the internet by early elementary school children should be monitored and strategies to promote familial conversations, activities with peers and school life satisfaction should be developed.

Purpose: This study was conducted in order to investigate factors associated with employment stress and the relationships among employment stress, depression, and body mass index (BMI) among college nursing students. Methods: Subjects included 319 students at two colleges in Kyonggi and Chungbuk province, who were asked to complete a survey questionnaire. T-test, ANOVA, Pearson's correlation coefficients, and multiple regression were used for statistical analysis of data. Results: Results of this study showed an average value of 53.39 for the total employment stress scale, and both values for familial environmental stress and school environmental stress were relatively higher among subscales of employment stress. The average score on the depression scale was 10.18 indicating slightly high, and BMI was 20.35 with an obesity fraction of 12.3%. In addition, the results also indicated that they suffered from much stronger employment stress according to their severity of depression. Overall factors that affect employment stress included depression, age, economic status, and whether family members live together or not. However, BMI had no significant statistical effect on employment stress. Conclusion: Results of this study suggest that it is necessary for students to measure and control their employment stress and depression, because employment stress is closely associated with depression.

Thyroid cancer is the most common endocrine neoplasia. The medullary thyroid carcinoma (MTC) is one of the most aggressive forms of thyroid malignancy,accounting for up to 10% of all types of this disease. The mode of inheritance of MTC is autosomal dominantly and gain of function mutations in the RET proto-oncogene are well known to contribute to its development. MTC occurs as hereditary (25%) and sporadic (75%) forms. Hereditary MTC has syndromic (multiple endocrine neoplasia type 2A, B; MEN2A, MEN2B) and non-syndromic (Familial MTC, FMTC) types. Over the last two decades, elucidation of the genetic basis of tumorigenesis has provided useful screening tools for affected families. Advances in genetic screening of the RET have enabled early detection of hereditary MTCs and prophylactic thyroidectomy for relatives who may not show any symptom sof the disease. In this review we emphasize the main RET mutations in syndromic and non syndromic forms of MTC, and focus on the importance of RET genetic screening for early diagnosis and management of MTC patients, based on American Thyroid Association guidelines and genotype-phenotype correlation.

This study aims to investigate variables affecting the business performance of Muslim women entrepreneurs in Sri Lanka. A multidimensional analysis was proposed with five potentially defined antecedents of business performance which included psychological characteristics, human capital, social capital, industrial factor, and cultural factor. Data was collected from 286 respondents through the use of a self-administered questionnaire. The results of structural equation modeling indicate that the model meets the goodness-of-fit indices and that generally, all five factors have significant positive relationships with business performance. Amongst the dimensions of psychological characteristics, only risk-taking had a notable effect on business performance. Amongst the dimensions of human capital, two of the three dimensions (business experience and business skills) were significantly associated with business performance; in the case of social capital, one of the two dimensions (non-familial affiliations) was significantly associated with business performance; and in the case of industrial factor, resource accessibility was significantly associated with business performance. A strong positive correlation with business performance has also been demonstrated by the cultural factor which was a new concept to the paradigm as a whole. This study has broadened the understanding of existing literature on Muslim women entrepreneurship and contributed practical implications to government, policymakers and other related agencies, chambers of commerce, the general public, as well as the Muslim women entrepreneurs themselves.

Purpose: This study examines the levels of adherence to quarantine guidelines, mental health, and instrumental activities of daily living among elderly individuals during the COVID-19 pandemic, and to identify correlations among these variables. Methods: A survey was conducted from February 28, 2023, to May 19, 2023, among 210 elderly individuals aged 65 and above residing in rural areas. The relationships among adherence to quarantine guidelines, mental health, and instrumental activities of daily living were tested using Pearson's correlation coefficients. Results: Loneliness was positively correlated with subdomains, including familial loneliness, social loneliness, and a sense of belonging, whereas depression was significantly negatively correlated with adherence to quarantine guidelines(cough etiquette, ventilation, mask wearing, and environmental disinfection) and rules of social distancing. Conclusion: Analyzing the various factors influencing adherence to quarantine guidelines among the elderly and developing and implementing intervention programs are essential for future research.
