We investigated the hydrological and geomorphological characteristics of small irrigation ponds in civilian control zone of Paju city in Korea. Among 85 small irrigation ponds, water level of 52 ponds changed seasonally and that of 33 was constant. Water sources of 12 ponds were surface water, 29 surface water and ground water, and 44 ground water. 4 ponds locate in the edges of forests, 33 in flat-lands, and 48 in valleys. Water in 45 ponds was exchanged with paddy fields and 40 ponds were isolated from paddy fields. Endangered or endemic species were inhabited in 26 ponds, which have ground water as water source and constant water level. Based on these characteristics, we suggested 4 types of small irrigation ponds: spring, water exchanging, stagnant/spring, stagnant water. This classification system will help ecosystem managers to investigate ponds systematically and manage them based on pond type.

The relative effects of individual differences in cultural orientation (individualism vs. collectivism) and locus of control (LOC: internal vs. external control beliefs) combination types on global/local processing were compared by manipulating the compound stimulus types (arrows or letters), and the stimulus-stimulus congruence. The results can be summarized as followings. First, consistent with previous research on global/local processing of the compound stimuli, reaction time (RT) for global stimuli than for local stimuli, and that in the stimulus-stimulus congruent condition than in the stimulus-stimulus incongruent condition was faster. Second, faster RT was found in the compound arrows condition than in the compound letters. Third, individual difference in LOC, rather than that in the cultural orientations, appeared to be related to global precedence effect, when the compound letters were presented. These results indicated that the individual's LOC rather than cultural orientation can increase the size of the global precedence effect, which might be involved in the stage of cognitive analysis than that of feature detection.

The purpose of this study was to investigate the effects of child care teachers' emotional supports in individual classrooms on children's social skills, including self-control, assertion, cooperation, and responsibility that were related to their character development. Data were collected in a purposive sample involving 32 teachers working with 646 children at age five and 555 parents of the children. Hierarchical Linear Modeling (HLM) was used to analyze a two-level model. The results showed that there were significant differences among classes with data reported by teachers but characteristics such as teachers' education and work experiences, child-teacher ratio, and type of child care centers as well as teacher's emotional supports did not explain the differences. Children's age and gender, which were predictors at the individual level, significantly explained their level of social skills reported by parents as well as teachers. The findings implied that other predictors influencing differences among classes should be explored in future studies.

The present study analyzed the KOCCA's Game Immersion data to explore the relationship between psychological traits and game immersion. Psychological traits were classified into four categories; emotional stability, self-esteem, willpower, and happiness. These were put into the multiple regression analysis as the dependent variables with age, sex (dummy), economic status of the homes, variety of leisure activities, friend and family relationship, and time to play games. Four types of immersion (psychological unstability, bad relationship, interrupted daily lives, and failure to control game time and desire) were put into the multiple regression analysis as the independent variables. The multiple regression analysis indicated that the dependent variables predicted the game immersion. Among the psychological traits emotional stability was the strongest factor (negative) that influences the game immersion. Next powerful indicator (negative) among the psychological traits was self-esteem. Based on the findings, measures to alleviate the problems of game immersion and ideas for further research were suggested.

This study attempts to investigate the parent's perception types of online game and their related factors. The data was collected through the online survey from 485 parents. As a result, the parent's perception types of online game were classified as 4 types. Each perception type shows differences in an attitude and reaction to online game and gender. Next, this study employed a multinomial logistic regression model to examine variables influencing the parent's perception types of online game. The result shows that parent's gender, controlling parental style, and problematic communication have statistically significant effects on the parent's perception types of online game. This study holds its significance in considering the game use of children in the context of parent-child relationship by exploring the parent's perception of online game and its influencing variables.

This study examines adolescent delinquent behavior and the influence of friends, focusing specifically on friends' delinquent behavior and the influence of self-efficacy, parent-child conflict and parental control. A total of 1,399 adolescents attending five different high schools (male=642, female=756, consisting of 915 student attending high school and 484 students attending vocational high school) completed a questionnaire developed by Ahn, Hwang, Kim and Park (1997) and Bandura's (1995a) self-efficacy scale. Results indicate that those students who attend high school had parents with higher education, socio-economic status and better studying environment at home, while students attending vocational high school had higher parent-child conflict. Students attending high school had higher self-efficacy scores, while students attending vocational high school had higher scores on delinquent behavior. The results of LISREL analyses revealed a similar pattern for high school and vocational high school students. Combined analysis indicate that friends' delinquent behavior, parent-child conflict and parental control had direct and positive effect on students' delinquency behavior. Self-efficacy had a direct and negative influence of delinquency behavior. Similar pattern was obtained for friends' delinquency behavior, in which self-efficacy had a direct and negative influence of their delinquency behavior and their parent-child conflict and parental control had direct and positive effect on their delinquency behavior. In summary, those students who had lower self-efficacy, higher parent-child conflict and parental control, and with friends who are more likely to engage in delinquent behavior, had higher scores on delinquent behavior. Also, those students who had friends with lower self-efficacy scores and with higher parent-child conflict and parental control are more likely to engage in delinquent behavior, which in turn influenced their delinquent behavior. Friends' delinquent behavior had the greatest influence on students' delinquent behavior indicating the role of friends in influencing delinquency among adolescents.

This study analyzed variables that affect children's leadership qualities. The subjects were 400 five-year-old children and their mothers living in the Seoul metropolitan area. The instruments used in this study were the Young Children's Leadership Scale (Kim, 2006), Temperament(Hong, 2008), Peer Interaction (Choi, 2004), Mother's Verbal Control Modes(Do, 1997), and the HOME instrument (Rhee and Jang, 1982). The data collected was analyzed by descriptive statistics, Pearson's correlation, and multiple regression analysis. Our results indicated that (a) girls' scores on leadership were higher than those of boys. (b) Boys' leadership qualities were related to children's temperament, peer relationship, maternal verbal control modes, and home environment. (c) Girls' leadership qualities were related to children's temperament, peer relationship, and home environment. (d) In particular, it was noted that children's temperament (in terms of their sensitivity/endurance) was the strongest predictor for leadership qualities in both boys and girls.

This study investigated subtypes of men who batter, and explored the differences among them. It was based on 217 subjects from all around the nation who received legal punishment. In the analysis of the typology, we specifically tested whether the Holtzworth-Munroe and Stuart proposed typology was verified. The results of the cluster analysis revealed support for their theoretical distinction for three types of abusers. These results imply that Holtzworth-Munroe and Stuart's batterer typology is applicable to Korean batterers to some degree. Type 1 men demonstrated the lowest levels of physical and psychological abuse toward their wives and were the least likely to have had a history of child abuse or alcohol problems. These men had lower MCMI scores and did not show any extraordinary personality traits. Men in this category were violent only against their wives, had relatively liberal sex role attitudes and had the most satisfaction in their intimate relationships. Type 2 men were violent only at home, using a moderate level of violence. These men had very high levels of dependency on others and showed a borderline, avoident or passive-aggressive personality. The amount of alcohol consumption was similar to Type 1, but scores of jealousy, self-esteem, and attitudinal variables were similar to Type 3 men. They lacked assertiveness skills and reported the least marital satisfaction. Type 3 men used the most severe violence and were violent both inside and outside the home. These men showed signs of antisocial and aggressive personality. They had experienced frequent physical abuse during childhood, were the most likely to abuse alcohol and had lower self-control. Type 3 were the most traditional in their views of women's roles and had attitudes supporting violence. Based upon the study findings, practical implications of enhancing treatment efficacy were considered.

In the studies on residential move, there has been tendency of dichotomy where short distance moves are largely caused by housing to adjust to changes in households while long distance moves are induced by shift in labor market. However, some empirical studies have proven that residential move is so complex process that the simple dichotomy should be elaborated. In this sense, the present study seeks to identify compounded course of residential move in Korea. In determining migration history, families with younger householders, renters, householders with higher educational attainment and smaller households show a higher probability to move. In case of mobility, women were more prone to move compared to man. Women compared to man, older age augmented the probability to own a house after migration. Families with householders following an occupation of sales and technical service showed lowest tendency to own houses while it marked the highest in the group of professionals. Higher land price of a region was negatively related to owning houses after migration. The present study revealed that factors in macro level as well as micro level significantly affect the move of individuals with varying effects in accordance with migration history.
