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.

This study examined the influences of product knowledge(subject knowledge, purchase experience and information search) on perceived risks and benefits to natural dyeing product. Data were collected from a total of 213 Korean females ranging from 20 to 50 years old who know natural dyeing product through online survey. There were significant differences between(or among) groups with different levels of subject knowledge, purchase experience and information search in several types of perceived risks and benefits to natural dyeing product. Consumers with high knowledge of natural dyeing product perceived several types of risks lower than consumers with low knowledge but they perceived several types of benefits higher than consumers with low knowledge.

The purpose of this research is to understand the general consumer knowledge and adoption intention of nanotechnology products, one of the advanced scientific fields. We examined consumers' knowledge of innovation products based on nanotechnology, by gender and age group, which are divided into benefits, cost, and trust perception. As a result, the benefits were highly perceived in the order of perceived usefulness, perceived gains, and perceived ease of use. In general, it was found that men and older age group perceived the benefits of nanotechnology to be relatively higher than women and younger age groups did. In terms of cost, perceived risk was relatively higher than other variables and a high innovation resistance appeared in the younger 30s group. Finally, we found that trust for nano-related institution is relatively lower than trust for nano-related people and trust for nanotechnology itself.

This study examined the effect of perceived risk, an under-explored area in the knowledge sharing literature. We proposed that employee perceptions of risk relate positively with their knowledge sharing behaviors (donating and collecting), and examined the mediating role of impression management strategies in the hypothesized relationships. We also explored the moderating effect of leader-member exchange (LMX) in the relationship between perceived risk and impression management strategies. Valid and reliable self-report and supervisory evaluation measures were collected from a sample of 251 railroad employees in safety-sensitive positions. The results indicate that perceived risk was not significantly associated with knowledge sharing, but rather the risk perception impacts were indirect through impression management strategies such as exemplification and supplication. The study also found that LMX has no moderating effect on the perceived risk and impression management strategies. In discussing these results, we present significant insights in terms of subjective risk judgment as a potential mechanism which can encourage organizational politics.

Purpose: The purpose of this study was to identify knowledge and the Need of pathophysiology, perceived connectivity between knowledge of pathophysiology and clinical practice, and confidence and satisfaction with clinical performance by applying the knowledge to clinical practice, and to analyze the correlation between the knowledge, perceived connectivity, and confidence and satisfaction of clinical nurses. Methods: Subjects consisted of 149 clinical nurses who work at 7 general hospitals and 6 university hospitals located in Seoul, Incheon, and Gyeonggi province in Korea. Those who learned pathophysiology during their undergraduate program were recruited by using a convenient sampling. The data were collected between April 23 and May 24 in 2012. Participants responded to self-administered questionnaires about knowledge and the need of pathophysiology, and the perceived connectivity between knowledge and clinical practice, and confidence and satisfaction with clinical performance by applying knowledge to clinical practice. Results: Mean scores of knowledge and the need of pathophysiology were $2.88{\pm}0.34$ and $2.33{\pm}0.39$ each. Scores of knowledge and the need of 3 units such as fluid and electrolyte imbalance, acid-base imbalance, and alterations in the respiratory system were high among 23 units while that of adolescent disorders was the lowest. The mean score of perceived connectivity between knowledge and clinical practice was $7.32{\pm}1.57$, and those of confidence and satisfaction with clinical performance by applying the knowledge to clinical practice were $7.66{\pm}1.66$ and $7.42{\pm}1.67$ respectively. Knowledge of pathophysiology was positively correlated with the perceived connectivity between knowledge and clinical practice, and confidence, and satisfaction with clinical performance. Conclusion: The results indicate that knowledge and the need of pathophysiology in clinical nurses is above average, and that knowledge of pathophysiology is important in promoting perceived connectivity with clinical practice and increasing confidence and satisfaction with clinical performance by applying knowledge to clinical practice.

Purpose The purpose of this study is to investigate the effects of learning expectation and perceived knowledge sharing on user satisfaction and IS continuance in the Korean Army which is currently using the Regiments' Information System to help their Integrated Administration Management. Based on both the Information System(IS) Continuance Model and IS Success Model, this study also examine the role of system quality on user satisfaction. We develop a research model(structural equation model) and its hypotheses that learning expectation, perceived knowledge sharing, and system quality increase users' satisfaction, which leads to IS continuance. The effect of learning expectation on perceived knowledge sharing is also hypothesized. Design/methodology/approach Online Survey using e-mails was administered to test our research model and associated hypotheses. Among the 360 e-mail letters including our survey questionnaire, 285 responses were collected via e-mails. Meaningful 225 cases were analyzed for our study. SPSS Statistics 24.0 and SmartPLS 3.0 were used to analyze both measuremant test and hyotheses test by using the data set. Findings Survey results show that learning expectation(confirmation variable), learning expectation, perceived knowledge sharing(a perceived usefulness variable), and system quality(a system characteristic) each increases user satisfaction, which leads to IS continuance, under the control of the effect of habit to use information systems. Learning expectation also has a positive influence on perceived knowledge sharing. Theoretical and practical implications are presented.

Objectives: This study was conducted to describe child perceived health knowledge, health education needs, and health behaviors by grade in a representative general characteristic and examined their associations for students' better health behaviors. 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 in the $4^{th}$ grade students than $5^{th}$ or $6^{th}$ grade students. That is, higher grade students had lower perceived health knowledge, lower health education needs, and lower health behavior status. Specifically, there was significant grade differences in 'significance of publichealth,' 'nutritionandhealthyeating,' 'desirablehealthhabits,' 'humansex,' 'physical development in childhood,' 'stress management & drugcontrol,' and 'injury prevention.' Correlations between perceived health knowledge and health behavior were low or medium in all grades. However, correlations between perceived health education needs and health were significant in the $4^{th}$ grade students but not significant in the $5^{th}$ and $6^{th}$ grade students. Conclusions: There was significant grade difference of the relationship between health knowledge, health education needs, and health behaviors among children. In general, the lower the grade the better the health knowledge, educational needs, and health behavior. Health education needs were more significant by grade than perceived health knowledge and health behaviors.

As web technologies evolve and so-called Web 2.0 technologies appear, collective intelligence is being applied in widespread areas. In general, mass collective intelligence like Wikipedia is created, revised, and managed by anonymous participants in an uncontrolled system. Thus, the knowledge provided by mass collective intelligence may be distorted, and may not be true, which may affect the user acceptance behavior. However, there have been few academic studies that analyzed the factors that affect user acceptance of mass collective intelligence, and their relationships. Under this academic background, we develop a model to examine how mass collective intelligence is accepted by users. The theoretical model is validated through an online survey of the Wikipedia users from three universities in Korea. The results reveal that the users will have positive attitude towards adopting mass collective knowledge when they perceive that the knowledge from mass collective intelligence is useful. We also find that the perceived usefulness of the knowledge is affected by perceived knowledge quality and trust in knowledge contributors. The results also suggest that perceived knowledge quality is determined by perceived level of collaboration, perceived objectivity, and recipient expertise, whereas trust in knowledge contributors is determined by natural propensity to trust and perceived objectivity. Theoretical and practical implications about mass collective knowledge are discussed.

The aim of this study was to estimate the effects of an early childhood environmental education program developed on the basis of relationships among preschoolers' knowledge, emotional attitude, and perceived behavior control of environmental pollution on their knowledge, emotional attitude, perceived behavior control, and behavioral intention. A total of 146 five-year-old preschoolers from eight child-care centers in Seoul and Kyoungki Province participated in this study. The following are the main results of this study. first, the higher the level of knowledge the preschoolers had, the more negative emotional attitude they displayed. Furthermore, the more negative emotional attitude they displayed, the higher the level of perceived behavior control they had. On the contrary, the relationships between knowledge and perceived behavior control varied with exposure situation to environmental pollution. Second, after the environmental education program was administered to the experimental group, the preschoolers from experimental group exhibited more knowledge, more negative emotional attitude, higher perceived behavior control and more active behavioral intention towards environmental pollution than those in the control group.
