The purpose of this study is to investigate the relationship between children and adolescents' moral emotions - empathy, guilt and gratitude - and helping behavior. For this study, questionnaires on empathy, guilt, gratitude and helping behavior were administered to 938 students in the 4th, 5th, 7th, 8th, 10th and 11th grades attending elementary, middle and high school in Seoul and Gyeonggi Province. The data were analyzed through frequency analysis, mean, standard deviation, t-test, one-way ANOVA, Pearson's correlation, enter multiple regression analysis and hierarchical multiple regression analysis by using SPSS Win 12.0. The main findings of this study are as follows: Firstly, by gender, empathy, guilt and helping behavior differed significantly, also, by grade, empathy, guilt, gratitude and helping behavior differed significantly. In addition, religion made a significant difference in empathy, gratitude and helping behavior. Secondly, variables influencing helping behavior were found to differ by developmental stage. The variable influencing the helping behavior of elementary school students was found to be empathic concern. For middle school students, guilt was found to influence their helping behavior, while for high school students, perspective-taking was found to be the key variable. Thirdly, gratitude was found to have a partial mediating effect on the relation between empathy(or guilt) and helping behavior.

성선자극호르몬 분비호르몬은 시상하부에서 분비되며, 포유동물의 생식에 중추적인 역할을 담당한다. 골든 햄스터는 계절적으로 번식하는 포유동물이며, 생식 활동은 광주기(하루 중 낮의 길이)에 의해 결정된다. 장주기(12.5 시간 이상의 빛)는 생식 능력을 유지시키지만, 단주기(12시간 이하의 빛)는 생식 기능을 억제한다. 성선자극호르몬 분비호르몬과 광주기의 상호 관계를 자세히 조사하기 위하여 랫트 성선자극호르몬 분비호르몬 cDNA를 포함하는 벡터를 여러 농도로 골든 햄스터의 수컷에 주입하고 단주기에 유지하여 생식 활동을 개별적으로 조사하였다. 벡터를 고농도로 처리한 그룹의 골든 햄스터는 기타 실험 그룹에 비해 정소 퇴화가 의미있게(P<0.05) 가속되었다. GnRH의 맥동적 분비가 생식 능력을 유지하는 관점에서 보면, GnRH-cDNA를 포함하는 벡터는 GnRH를 일정하게 고농도로 분비했다고 사료된다. 이 결과는 GnRH를 포함하는 벡터가 뇌하수체 전엽을 desensitization시켜 정소 퇴화를 가속시켰음을 암시한다.

The purpose of this study was to examine the mediating effects of rapport on the relationship between type of organizational culture and innovative behavior of hotel chefs. In order to accomplish the research purpose, data were collected from 202 chefs working at five-star hotels located in Gwangju and Jeonnam areas, and SPSS 22.0 Program was used to conduct frequency analysis, reliability analysis, exploratory factor analysis, regression analysis and mediation effect analysis. The results of the study were as follows. Firstly, it was found that innovative behaviors of hotel chefs are significantly affected by three types of organizational culture: rational culture, consensual culture, and developmental culture. Secondly, it was found that rational and consensual culture have significant effect on rapport. Thirdly, it was found that better-formed rapport in hotel chefs significantly remarkably influences their innovative behavior. Fourthly, the study results revealed that rapport has a mediating effect on the relationship between type of organizational culture and innovative behavior of hotel chefs. Thus, in order to induce voluntary innovative behaviors from building rapport in the hotel organization, it is necessary to develop and implement effective strategies which will form a work environment where chefs can freely engage in mutual exchanges and build trust with one another.

Although a family-centered approach to health care for developmentally disabled children has been advocated, existing systems of care have not adequately addressed the support needs of the family system and the essential role that parents play in the daily care of these children. The overall purpose of this research is to examine family system adaptation to the care of a developmetally disabled child using the Resiliency Model of Family Stress, Adjustement, and Adaptation Framework. Relationships among family system demands (stressors, strains, transitions, child's illness factors) and family system strengths and capabilities(resource of social support) were examined to determine their separate and combined contribution to explanining the variability in family system outcomes (family system coping ). The subject for this study was 46 families who have a child with developmental disabilities(mental retardation and / or autism) from three special educational programs in Seoul, Korea. Results from correlation and hierachial regression analysis revealed that perceived social support operated as a resiliency factor between family stress and coping. Child and family characteristics appeared to be important predictors of perceived social support and coping. In summary, there is evidence that the resource of social support as a family strength and capability was found to improve the family coping. These findings also must be viewed within the context that sample of families of children with disabilities was relatively small and eligible families from support group of special educational program.

Purpose: This study aimed to identify psychosocial factors associated with smoking cessation attempts among Korean high school students who engage in intermittent and light smoking. Methods: Cross-sectional secondary data derived from the 2018 Korea Youth Risk Behavior Web-Based Survey were analyzed within the framework of the biopsychosocial model. The sample comprised 829 high school students who reported current intermittent and light smoking, which was defined as cigarette smoking on 1~29 days in a 30-day period and no more than 10 cigarettes per day. Purposeful selection logistic regression analysis was performed. Results: In total, 71.7% (n=586) of the respondents had tried to stop smoking during the past 12 months. The main result was that respondents who had viewed an anti-smoking advertisement in the past year significantly more smoking cessation attempts than those who had not (adjusted odds ratio=2.59; 95% confidence interval=1.45~4.62, p=.001). Conclusion: To encourage smoking cessation attempts among high school students who engage in intermittent and light smoking, healthcare providers, including school and community nurses, should develop effective interventions using anti-smoking advertisements tailored to adolescents' interests and developmental stage.

Purpose: This study was to explore the prevalence of alcohol experiences and to identify the expectancy on the effects of alcohol and alcohol knowledge in early adolescents. Method: The cross-sectional survey of 1854 students from seven middle schools in one district of Seoul was conducted by convenience sampling. Alcohol experience and early onset of alcohol use were measured by the Youth Risk Behavior Survey. Alcohol expectancy was measured by an Alcohol Effects Questionnaire. Result: Over sixty five percent of adolescents reported that they had previous drinking experiences. The participants with no alcohol drinking experience had a lower level of alcohol knowledge than those with experience(t=2.73, p=.007). In expectancy on effects of alcohol, girls had a more positive alcohol expectation than boys(t=-2.54, p=.011). Alcohol knowledge negatively correlated with alcohol expectancy(r=-.40 p=.000). In regression of alcohol expectancy, gender and alcohol knowledge were significant predictors explaining 17%. Conclusion: The results support that alcohol expectancy is an important link with early drinking experiences and alcohol knowledge, focusing on the importance of gender differences. Therefore, an alcohol prevention program in early adolescence is needed and should be focused on multidimensionality of the alcohol expectancy with developmental and psychosocial factors for early adolescents.

Purpose: The purposes of this study were to explore knowledge, barriers, and self-efficacy in relation to pain management practice, and to identify factors influencing pain management practice in pediatric nurses. Methods: A descriptive correlational study was conducted. The participants were 237 pediatric nurses from a metropolitan city. Data were analyzed using t-test or analysis of variance and Pearson correlation and multiple regression analyses. Results: The mean percentage of correct answers on the children's pain management knowledge scale was 58.8%. Child and parent related factors were the main barriers for pain management. Self-efficacy to assess children's pain across developmental stages was particularly low. Pain management practices for assessing pain and non-pharmacological interventions were relatively low. Factors significantly affecting children's pain management practice were current conditions of work department and self-efficacy in pain management, and these factors accounted for 37.5% of the variance in pain management practice. Conclusion: The results suggest that an integrative education program needs to be developed to improve self-efficacy in children's pain management practice. Moreover, good communication, building cooperative relationships with children and parents, and a more active role by pediatric nurses are required to carry out more effective pain management.

Objective: This study examined that general characteristics such as gender, age, period of stay at an institution, size of facility, and temperament and attachment affect young children's development under institutional care. Methods: A total of 94 young children (ages 2-4years), who live in 32 institutions in Seoul were assessed on their development using the Korean-Age & Stage Questionnaire. Pearson productmoment correlation analysis, and multiple regression analyses were used for data analysis. Results: The major findings of this study were as follows: first, a longer period of stay at an institution had more positive effects on the development of communication. Facilities with more than 60 children had lower communication, gross motor, and fine motor development compared to facilities with less than 60 children. Second, social temperament had positive effects on communication, problem solving, and personal-social development. Emotional temperament had no effects on all development areas. Third, attachment had positive effects on all development areas. Lastly, social temperament and attachment had interactive effects on communication, gross motor, problem solving, and personal-social development. Conclusion: These results imply that caretakers in institutions should give developmental mediation services for considering temperament and facilitation of attachment.
