The purpose of this study was to identify the influence of compassion fatigue, compassion satisfaction and nursing organizational culture on burnout in integrated nursing care units nurses. The participants were 170 nurses working in integrated nursing care units of three general hospitals located in Seoul and Gyeonggi-do. Data were analyzed using independent t-test, ANOVA, Scheffé, Pearson's correlation and stepwise multiple regression analysis. Burnout was significantly different according to turnover intention, job satisfaction, health status. Burnout showed a positive correlation with compassion fatigue and a negative correlation with compassion satisfaction and relation oriented culture. Regression analysis revealed that compassion fatigue, compassion satisfaction, relation oriented culture and age were significant variables affecting the burnout, and the lower the age, the higher the burnout. Therefore, strategies to decrease compassion fatigue and to enhance compassion satisfaction and positive aspects of relation oriented culture for lower age nurses group are needed.

This paper compares three statistical models that examine the relationship between national and provincespecific fertility rates. The three models are two of the regression models and a cointegration model. The regression model is by substituting Gompit transformation for the cumulative fertility rate by the average for ten years, and this model applies the raw data without transformation of the fertility data. A cointegration model can be considered when fitting the unstable time series of fertility rate in probability process. This paper proposes the following when it is intended to derive the relation of non-stationary fertility rate between the national and provinces. The cointegrated relationship between national and regional fertility rates is first derived. Furthermore, if this relationship is not significant, it is proposed to look at the national and regional fertility rate relationships with a regression model approach using raw data without transformation. Also, the regression model method of substituting Gompit transformation data resulted in an overestimation of fertility rates compared to other methods. Finally, Seoul, Busan, Daegu, Incheon, Gwangju, Daejeon and Gyeonggi province are expected to show a total fertility rate of 1.0 or less from 2025 to 2030, so an urgent and efficient policy to raise this level is needed.

This study examined if any differences exist of young children's physical and relational aggression as affected by aggression levels, teacher-child and peer relationship, age, and gender. Furthermore, the extent of physical or relational aggression of the young children influencing teacher-child relationships is also examined. In this study, two hundred and fifty children aged three to ten and fifty-two teachers were targeted. They responded on questionnaires in regard to aggression, teacher-child relationships, and peer relationship. The findings are as follows: First, in terms of child aggression according to his/her age, it has been shown that physical aggression is primarily present in the age of four. Second, concerning gender, boys are found to be high in levels of both relational and physical aggression. Third, the data shows that in the relationship between the child's aggression and teacher-child relationship, the higher the child's aggression, the lower the intimacy of relationship between child and teacher and the higher the dependence and conflict in the relationship of teacher and child. Fourth, in the examination of relationships between a child's aggression and peer influence, higher levels of relational and physical aggression correlate with higher aggressive, hyperactive, and anti-social behaviors. In addition, the higher the age and relational aggression, the higher the pro-social behaviors that occur. Pedagogical implications and suggestions are put forth in the areas of improving relationships between children and teachers, how teachers can assist young learner development, and techniques to improve peer relationships and reduce its difficulties.

Age and growth of stone flounder kareius bicolortus in approaches to Kyongyolbiyolto of Yellow sea were studied by otolith reading of 248 fishes from September 1992 to August 1993. Examination of the ourter margins of the otoliths showed that th hyaline zone as annulus was formed once a year and that its formation was completed at the end of the spawning season(Jan. to Feb.). Growth of the fish was expressed by the von Bertalanffy's equation as Lt=313.7[1-exp{-0.463(t+0.0704)}] for males and Lt=478.6[1-exp{-0.286(t-0.1619)}] for females, where Lt is body length in mm and It is age in years. It was found that growth of males and females differs, with the females showing a higher growth than the males. Growth in body weight was also examined. The oldest fish were seven years old for males and females.

Purposes : This study was performed to evaluate the seropositivities and levels of term pregnant women and their neonates, and the transplacental transfer rate of maternal Epstein-Barr Virus-specific IgG(VCA IgG and EBNA IgG) from term pregnant women to their neonates. Subjects and Methods : During Jan. 1, 1997 to Mar. 31. 1997, we collected the 42 pairs of sera from pregnant women and umbilical cord of their neonates in Korea University Ansan Hospital. The serum levels of VCA IgG and EBNA IgG were measured by the ELISA method. Results : 1) The seropositivities of VCA IgG were 100% in mothers and neonates. There was no statistical difference of mean VCA IgG levels between mothers and neonates. There was significant correlation of VCA IgG levels between maternal sera and neonatal umbilical cord sera(correlation coefficient r=0.5214, P<0.001). 2) The seropositivities of EBNA IgG were 100% in mothers and neonates. There was no significant difference of the mean EBNA IgG levels between mothers and neonates. There was significant correlation of EBNA IgG levels between maternal sera and neonatal umbilical cord sera (correlation coefficient r=0.7244, P<0.001). 3) There was no correlation between VCA IgG and EBNA IgG levels of maternal sera. Conclusion : Seropositivities of EBV CA IgG and EBNA IgG of term-pregnant women and their neonates were 100% and no significant differences of antibody levels were found in two groups. It seems that EBV Antibody levels in Korean mothers and neonates were high enough to protect primary EBV infection during early infancy.

본 연구의 일차적 목적은 어머니의 특성과 관련된 요인들이 양육효능감에 미치는 영향을 살펴보고, 양육효능감이 어머니의 특성과 관련된 요인들과 자녀양육 행동과의 관계에서 매개역할을 하는 것인가를 분석하였다. 그리고 양육효능감, 자녀 양육행동, 아동 발달과의 상관관계를 살펴보았다 미국 내 거주하는 Early Head Start 프로그램 의 수혜 자인 저 소득층의 어머니와 영 아들을 (출생∼36개월) 대상으로 한 본 연구결과에 의하면 어머니의 특성과 관련된 요인들로 어머니의 연령, 소득수준, 양육에서 오는 스트레스가 양육효능감에 영향을 미치는 것으로 나타났다. 양육효능감은 어머니의 특성과 관련된 요인, 특히 어머니의 연령과 양육행동과의 관계에서 매개역할을 하는 것으로 나타났다 양육효능감, 양육행동, 아동발달과의 상관관계 분석에서는 양육효능감과 양육행동에서만 유의한 정적인 강관관계가 있는 것으로 나타났다. 지금까지의 선행연구들과는 맥을 같이하는 연구결과이지만, 저소득층(high-risk families)의 어머니와 영아를 대상으로 양육효능감을 포괄적이고 체계적으로 이해하고자 하였다는데서 의의를 찾을 수 있다. 나아가, 이 연구의 결과는 저소득층을 위한 아동 및 가족의 통합적 복지사업을 실천하는데 있어 의미가 있는 것으로 시사된다. 사회 경제적 자립을 위한 기회 제공과 자녀양육을 하는데 있어서 전문가의 직접적인 모델링을 통한 부모교육을 통해서 양육효능감을 향상시켜나갈 때, 아동 및 가족 복지 실현의 궁국적 목적을 이룰 수 있을 것이다.

The purpose of the study is to propose and evaluate Exploratory Spatial Data Analysis(ESDA) methods for examining age-specific population migration characteristics. First, population migration pyramid which is a pyramid-shaped graph designed with in-migration, out-migration, and net migration by age (or age group), was developed as a tool exploring age-specific migration propensities and structures. Second, various spatial statistics techniques based on local indicators of spatial association(LISA) such as Local Moran''s $I_i$, Getis-Ord ${G_i}^*$, and AMOEBA were suggested as ways to detect spatial dusters of age-specific net migration rate. These ESDA techniques were applied to age-specific population migration of Daegu Metropolitan City. Application results demonstrated that suggested ESDA methods can effectively detect new information and patterns such as contribution of age-specific migration propensities to population changes in a given region, relationship among different age groups, hot and cold spot of age-specific net migration rate, and similarity between age-specific spatial clusters.

사람들은 주변의 영향을 받아 가면서 각자의 독특한 글쓰기 양식을 만들어간다. 따라서 같은 연령대와 성별을 가지는 사람들은 유사한 글쓰기 양식을 나타내는 경향이 있다. 이와 같은 가정을 바탕으로, 본 연구에서는 다양한 연령대와 성별의 사람들이 작성한 트윗의 문체를 분석하여 임의의 트윗을 작성한 저자의 연령대와 성별을 예측하는 실험을 진행하였다. 한국어 웹 언어에서 자주 보이는 표현들을 토대로 구성한 자질들과, 그에 비해 데이터와 관계가 적은 n-gram 단위의 자질들을 함께 사용하여 예측을 진행함으로써, 최대 공산 기준치보다 25%가량 높은 정확도를 보이는 예측 결과를 얻게 되었다. 이와 함께 각 자질 구성이 예측에 얼마나 효율적으로 기여하는지에 대한 이해도를 높일 수 있었다.
