Objectives: This study was conducted to describe child perceived health knowledge, health education needs, and health behaviors by sex as a representative general characteristic and examined their associations for students' better health behavior changes. Methods: The survey participants were 410 fourth to sixth grade students in two elementary schools in Seoul, Korea. A total of 12 classes in two elementary schools were randomly selected and all students of the selected classes participated in the self-administered survey. The questionnaire contained the items of perceived health knowledge, health education needs (health topics which they want to know more), health behavior, and general characteristics. Results: Perceived health knowledge, health education needs, and health behaviors were, generally, better among girls than boys. Sexual differences were not large in perceived health knowledge, health education needs, health behaviors. Perceived health knowledge had significant positive correlation with health behaviors both in boys and girls(p <.01). The correlation between perceived health knowledge and health behaviors(r =.36) was two fold greater than correlation between health education needs and health behaviors(r =.18) among boys; where as the two correlations were similar to each other among girls. The significant factors were perceived health knowledge, sex, grade, and health education needs in order, and the four factors described health behaviors in 21.0%. The higher perceived health knowledge, girls, lower grade, and more health education needs was associated with the better health behaviors. Conclusions: There was significant sexual difference of the relationship between health knowledge, health education needs, and health behaviors among children. Perceived health knowledge was more important factor to improve health behaviors among boys while perceived health knowledge and health education needs had equal importance on health behaviors among girls. Therefore, knowledge building should be an essential part of health education class goals for building better health behaviors.

Metastable statates, resonant states in 4s level and excited states in 4p level were investigated with a simple global model and examined by the LIF experiments. Metastable states exhibit an anomalous behavior with the plasma density, on the other hands, other states show monotonous increasing behaviors. It turns out that the metastable state can have such an anomalous behavior due to its special characteristic, electric dipole radiation forbidden. It is expected to resolve the ambiguity of previously reported metastable density behaviors and provide further understanding.

Data were collected from 514 elementary school students from 1st to 6th grade with questionnaires on Parental Behavior, Bullying, and Peer-Victimization. Sixth graders reported the lowest perception of warmth-acceptance, and 1st graders reported the highest perception of rejection-restriction by fathers. Males perceived more parental rejection-restriction. Children perceived more warmth-acceptance from mothers, and they perceived more permissiveness-nonintervention from fathers. Parenting behaviors were significantly related to bullying and victimization. The Bullying/Victimization group reported the lowest parental warmth-acceptance. Both Victimization and Bullying/Victimization groups showed higher parental rejection-restriction than other groups. The Victimization group showed highest paternal permissiveness-nonintervention. Victimization and Bullying/Victimization groups reported higher maternal permissiveness-nonintervention than other groups.

The purpose of this research is to study differences in perceived parental neglectful behaviors between siblings from a child's perspective. The data were collected using the Multidimensional Neglectful Behavior Scales (MNBS) questionnaire from 158 sibling pairs in grades 4, 5, and 6 who attended the same elementary schools. Younger sibling experienced emotional neglect by their parents significantly more than older siblings. Same gender sibling pairs and older brotheryounger sister pairs perceived their parental neglectful behaviors in a similar manner. However older sister-younger brother pairs showed that the younger brother perceived significantly more neglect than his older sister. This study clearly illustrated that siblings' perceptions of their parents' neglectful behaviors exists differently within a family contrary to previous studies which have shown that siblings' perception of parental neglectful behaviors are similar. The results suggest that the younger brother in mixed-gender sibling pairs are far more likely to experience neglect than any other sibling. Thus, even though siblings can be at equal risk in experiencing parental neglect, the effects can vary depending on the birth order.

This study was intended to examine the effects of socioeconomic status on housing values, norms, and behaviors of young households. The purpose was accomplished using the Life Style Survey of 2001 in Ulsan, and the data from 370 households were analyzed. The importance of household income and current housing size which are used as a proxy for socioeconomic status in explaining housing values, norms, and behaviors were once again confirmed in this study, even if there were some other significant variables. This implies that housing values, norms, and behaviors tend to change according to the socioeconomic characteristics of the households under the conditions of controlling demographic ones.

Microblog services are such new communication channels with some considerable potential to improve information sharing. The idea of sharing short messages using multiple access points seems to be appealing to people worldwide. Through the lens of flow and social identity, we explored factors that influence information sharing behaviors in microblog services. With an empirical study, we examined enjoyment and concentration(flow) and self-presentation(social identity) in microblog services like twitter can contribute to the user behaviors. Our aim was to gain insight into ways of creating an environment that facilitating voluntary sharing of information. Our findings suggested that enjoyment, concentration, and selfpresentation were crucial determinants of information sharing behaviors in microblog services. This study has important implications for academic researchers and practitioners who seek to understand why microblog service users share their information with other members in microblog services.

This study investigated the effects of maternal parenting behaviors and preschooler's emotional regulation on their internet-game addictive inclination. The participants were 129 mothers of 5 and 6 year-old preschoolers and their teachers from two day dare centers and one kindergarten in Seoul and Kyung-gi province. Data were analyzed by descriptive statistics and hierarchical regressions by SPSS program (12.0 version). The major findings were as follows: (1) Boys showed higher score of internet-game addictive inclination than that of girls. (2) mother's consistent parenting behaviors and preschooler's other-regulation behaviors significantly explained preschooler's internet-game addictive inclination. In conclusion, maternal parenting behaviors and preschooler's emotional regulation have influenced on preschooler's internet-game addictive inclination.

The differences of coping behaviors of professional and non-professional working mothers were assessed using data(n=704) from the working mothers with children under age 18. Professional working mothers' individual characters family and occupational conditions are more suitable than non-professionals for the coping behaviors. And such individual and situational aspects may relate to the differences of coping behaviors of he two groups. In general professional working mothers use coping behaviors more except the 'role reducation' and 'taking the support of fiends & neighbor' On the other hand the conservativeness and passive attitude in role strain coping is the same aspect of the two groups. Finally the relation of individual character family and occupational condition of working mothers to their coping behavios are slightly different in this two working mothers groups.

This study examines the effects of health-promoting behaviors of grandmothers participating in their infant grandchildren's nurture and provides data for enhancing the quality of their lives. The sample included 218 consenting subjects who understood the purpose of the study. These subjects resided in three cities in Jeollanam-do, Korea, and were grandmothers entrusted by their adult children with a considerable amount of nurturing for their preschool-aged grandchildren under the age of six. First, the subjects scored an average of 3.05 for health-promoting behaviors and 2.42 for entrapment. Second, the entrapment measurement based on general characteristics showed a higher level of entrapment for those with better health, a lower education level, no religion, male grandchildren to nurture, and unsatisfactory compensation. Third, health-promoting behaviors and entrapment (r=-.304) were negatively correlated. Fourth, the analysis results for effects of health-promoting behaviors of grandmothers on entrapment based on general characteristics of grandmothers as a control variable reveal a significant effect of health-promoting behaviors on entrapment. In other words, the greater the employment of health-promoting behaviors, the less likely the entrapment was to be perceived. Fifth, the results for effects of subcriteria for health-promoting behaviors on entrapment reveal a decrease in entrapment when the subjects engaged in an appropriate level of physical activity with a relaxed state of mind. These results suggest that health-promoting behaviors of grandmothers participating in their infant grandchildren's nurture are likely to influence entrapment and thus that grandmothers should make efforts to actively engage in health-promoting behaviors to reduce any maladaptive effects on nurturing. Social support and related programs should be fostered to enable grandmothers to better practice health-promoting behaviors while nurturing their grandchildren.

Ball reducer (HERB Drive: High Efficient Wave Rolling Ball Drive) with waved grooves has many advantages over other types of reducers for high-reduction ratio, low noise and low energy loss, etc. The mechanism of force transmission is very similar to that of cam and follower in automobile valve train system especially in contact behaviors. In this study, we have investigated the traces of contact between ball and outer ring, and the dynamic contact behaviors of elastohydodynamic lubrication(EHL) with a certain reduction ratio. In order to verify the contact behaviors between ball and outer ring for the critical endurance lift, the contact velocity and load are computed for a cycle. During some intervals of a cycle, the contact velocity reverses its direction very suddenly. It is expected that changing the contact direction causes undesirable endurance performance because EHL film frequently col lapse at the moment of velocity reversal. From the computational investigation in this work, we hope to predict similar contact damages in other machinery due to this kind of contact behaviors, which is very typical in many contact phenomena.
