The Study reported here was designed to analyze the prevalence of Dental Caries in the primary teeth of monozygote twins, and to ascertain and compare the intrapair differences with the intrapair differences in control pairs. The prevalence of dental caries in the primary teeth of 40 pairs of presumably monozygote twins, based on phenotypic analysis, was studied. The age range was from 3 to12 years. The control group consisted of pairs that included a twin chosen at random and an unrelated child of the same sex and age, so that for each pair of twins there was a corresponding control pair. The clinical examination was carried out by an operator using an oral mirror and sharp explorers, and with good lighting. 40 pairs of twins were examined with a total of 4,950 primary tooth surfaces (990 primary teeth) and 40 control pairs with a total of 4,935 primary tooth surfaces (987 primary teeth). Five surfaces were considered for each tooth. After the def individual index was determined, the ratio between this index and the number of examined surfaces was established in each case, the cer (Caries experience rate) index. The def and cer averages were determined for the subjects and the controls. All intrapair differences in twin and control groups were compared following the paired sampling method. The following conclusions were made: 1. Intrapair differences in the control group were significantly greater than in twins, when defs, ds, es, fs, and cer were compared. 2. The genotype appeared to be a determining factor in dental caries susceptibility or resistance, although the environment played an important role as well. 3. Intrapair differences in American children were significantly greater than in Korean when defs, es, fs, and cer were compared, but ds was equal.

Purpose: The purpose of this study was to compare the relationships among parent-child communication, self-esteem and sexual assertiveness for male and female university students. Methods: This descriptive study used a comparative survey design that utilized self-report questionnaires. A total of 470 participants were male and female university students in B metropolitan city. Results: The degree of open communication use was higher for female students in comparison to male students, There were no differences in dysfunctional communication for both the father-child communication. There were no differences between males and females for the mother-child communication either. The degree of self-esteem was higher for male students in comparison to the female students. The degree of sexual assertiveness was higher for female students in comparison to the male students. The grade, religion, major, allowance source, marital status of parents, and relationship experience with opposite sex were influencing factors for the male students' sexual assertiveness whereas the individual's major and physical contact were influencing factors for the female students. Conclusion: Self-esteem and mother-child open communication were influencing factors of sexual assertiveness. Thus, the nursing intervention based on the influencing factors is needed in order for male and female students to express sexual assertiveness.

Background: This study investigated the hearing status in Korean adults according to data from the Korea National Health and Nutrition Examination Survey 2009. Methods: The data of 3,479 adults(${\geq}20$ years, 1,492 men, 1,987 women) collected by the Korean Center for Disease Control was analyzed using ${\chi}^2$-test and logistic regression. Results: Differences in hearing loss according to individual factors were evident by follows gender, region, education status, economic status, current smoking and recognition of stress. Differences in - hearing loss according to ear related factors were evident subjective hearing status, experience of tinnitus, prevalence of chronic otitis media, and tympanomembrane abnormality. Conclusion: Hearing-related disorders can cause many social problems. This study investigated a representative cross-section of Koreans to determine the hearing status. The study was limited in that the risk factors of hearing loss were not identified. It is also recommended that a program be developed that can help control the variables identified in this study along with follow-up studies to verify the model.

This study identifies and tracks changes gender differences in adolescent users' problematic online behavior. This study used Korea Youth Panel Survey (KYPS), which has tracked respondents over 7 years, with self-control theory and social learning theory applied as a theoretical framework. The model included individual-level variables such as self-control and respondent's experience of problematic behavior (offline), as well as socialization variables such as the number close friends who engaged in problematic offline behavior, parent-child relationships, and parental monitoring. Dependent variables included problematic online behavior, unauthorized ID use (ID theft) and cyberbullying (cursing/insulting someone in a chat room or on a bulletin board). Control variables consisted of academic performance, time spent on a computer, monthly household income, and father's educational attainment. Random and fixed effects models were performed by gender. Results supported self-control theory even for the within-level analysis (fixed effects models) regardless of gender, while social learning theory was partially supported. Only peer effects were found significant (except for unauthorized ID use) among girls. Year dummy variables showed significant negative associations; however, academic performance and time spent using computers were significant in some models. Father's educational attainment and monthly household income were found insignificant, even in the random effects models. We also discuss implications and suggestions for future research and policy makers.

This study utilized the raw data from the Community Health Survey (2023) to compare differences in body function, activity, participation, environment, personal factors, and suicidal ideations between elderly individuals aged 65 and older living alone and those living with families in Korea. The study subjects consisted of 80,618 elderly individuals aged 65 and older. Cross-tabulation analysis χ²-test), independent sample t-test, and logistic regression analysis were conducted. The results indicated that for both elderly individuals living alone and those living with families, age(p<.001), smoking(p<.001), stress(p<.001), depression experience(p<.001), and falls experiences(p<.001) were risk factors that increased suicidal ideations. Conversely, educational level(p<.05), income level(p<.001), subjective health status(p<.001), social participation(p<.001), economic activity(p<.001), community environment(p<.001), and social relationships were protective factors that reduced suicidal ideations. These findings demonstrate that demographic characteristics and individual health status significantly influence suicidal ideation in the elderly, while social factors contribute to a decrease in suicidal ideation. Furthermore, considering the differences found between elderly individuals living alone and those living with families regarding hypertension and gender, differentiated interventions for suicide prevention are necessary.

The purpose of this study was to search and analyze the realities and needs of life long education, the necessity and perception of life competencies and the difference of competencies on experiences of education to support life long education system for adult learners in Busan and Ulsan. In this study, we conducted a questionnaire survey of 234 adult learners living in Busan and Ulsan. The results of this study were summarized as follows. First, adult learners perceived that life long education was very important to adults and appreciated an educational institution being managed by government. Second, adult learners thought that basic literacy competency and basic work competency were important and late fifties perceived that professional job is in important. Third, adult learners perceived that self directed learning and capacity of management are poor competencies. And they perceived that the government support adult learners who has economical difficulty. Forth, adult learners perceived that it was normal that 'professional job' and 'job transition abilities', 'women', 'the middle aged and old','the unemployed' and' low incomers' perceived that they have poor level. Fifth, according to the results of ${\chi}^2$ test for determining the statistical significance of differences in experience in lifelong learning among adult learner groups divided by their individual background, significant differences were observed in a few competencies(p<.05, p<.01).

Purpose: We evaluated the status of patients enrolled in South Korea's pediatric palliative care pilot project based on the experience of a single center. This study examined factors related to end-of-life services and differences in medical costs. Methods: The medical records of 120 patients referred by a pediatric palliative care team were analyzed retrospectively. Data from July 1 to February 28, 2022 were collected and analyzed using the chi-square test and the Mann-Whitney U test. Results: Volunteer programs and psychological support (100%), family support and education (99.2%), and financial support through institutional linkage (62.5%) were provided to the participants. In the deceased group, there were no significant differences in general characteristics, which included age, gender, primary disease, religion, duration of hospitalization in an intensive care unit (ICU) and non-intensive care unit (non-ICU). However, the ICU group had fewer opportunities to access individual pain and physical symptom management than the non-ICU group and there were limitations in linking with external resources. Medical expenses were significantly different for the ICU group, with a 3-times higher average cost than the non-ICU group. Conclusion: Although an individualized approach is needed for each patient in pediatric palliative care, psychosocial care is essential. In addition, if early intervention for end-of-life pediatric patients is available from a palliative care team, the cost burden of medical care for patients and their families should be minimal.
