The purpose of this study is to develop a survey tool of scientific character for elementary student which connects science education and character education effectively by figuring out traits of elementary students' character being presented in teaching and learning context of elementary school science. For this, we adapted the theocratical model from the previous research which defined scientific character as the competencies being able to practice in concrete teaching and learning context of science. Based on this model, we developed the survey tool as 'Scientific Character Inventory for Elementary Student' to assess elementary students' scientific character as the competences to practice the virtues being pursued in the context of elementary school science and verified its reliability and validity. As a result of an exploratory and confirmatory factor analysis, we confirmed all the items could be summarized into 28 items and eight constructs such as scientific problem-solving, self-management, self-reflection, communication, interpersonal skill, community participation, global citizenship, and environmental ethics awareness. We found that minimum reliability coefficient of constructs was over than 0.5 and reliability coefficient of the total items was 0.878. And also, there was modest relationship between each construct and the total score of scientific character. These results show that the developed survey tool can be useful in evaluating the effectiveness of science character education. This study is meaningful in that it systematically reveals constructs of scientific character which can be raised in concrete context of science teaching and learning so as to suggest the survey tool to assess this.

The purpose of this study was to analyze recognition characteristics of science gifted students on the earth system based on their thinking style. The subjects were 24 science gifted students at the Science Institute for Gifted Students of a university located in metropolitan city in Korea. The students' thinking styles were firstly examined on the basis of the Sternberg's theory of mental self-government. And then, the students were divided into two groups: Type I group(legislative, judicial, global, liberal) and Type II group(executive, local, conservative) based on Sternberg's theory. Data was collected from three different type of questionnaires(A, B, C types), interview, word association method, drawing analyses, concept map, hidden dimension inventory, and in-depth interviews. The findings of analysis indicated that their thinking styles were characterized by 'Legislative', 'Executive', 'Anarchic', 'Global', 'External', 'Liberal' styles. Their preference were conducting new projects and using creative problem solving processes. The results of students' recognition characteristics on earth system were as follows: First, though the two groups' quantitative value on 'System Understanding' was very similar, there were considerable distinctions in details. Second, 'Understanding the Relationship in the System' was closely connected to thinking styles. Type I group was more advantageous with multiple, dynamic, and recursive approach. Third, in the relation to 'System Generalization' both of the groups had similar simple interpretational ability of the system, but Type I group was better on generalization when 'hidden dimension inventory' factor was added. On the system prediction factor, however, students' ability was weak regardless of the type. Consequently, more specific development strategies on various objects are needed for the development and application of the system learning program. Furthermore, it is expected that this study could be practically and effectively used on various fields related to system recognition.

This study was conducted to investigate and compare the degree of professional self -concept (PSC) of the psychiatric mental health nurse practitioners (PMHNP) in hospitals and public health centers and to identify the factors predicting PSC of them, in order to provide basic data for developing PSC increasing program PSC. The 355 PMHNP were sampled from the university or general hospitals. mental hospitals, community mental health centers and public health centers across the country. The scales used in this study were PSCNI by Arthur (1990), PSI by Heppner & Petersen (1982) and the Index of work satisfaction by Slavitt et al. (1978). The results of the study were as follows : 1. The average item score of PSCNI of PMHNP in hospitals was $2.83\pm0.27$, and that of PMHNP in public health centers was $2.76\pm0.28$. There was significantly different between two groups (p=0.0202) 2. A comparison of the scores for the dimensions of the PSCNI were as follows ; the mean item score of professional practice of nurses in hospital was $2.90\pm0.30$, and that in public health centers was $2.83\pm0.35$. There were significant differences between two groups in the scores of professional practices (p=0.0315), leadership (p=0.0071) and skills (p=0.0231). 3. There were significant differences between two groups according to education (p=0.0057) with no significant interaction effect of group and education. 4. Job satisfaction (JS) was the highest factor predicting PSC of PMHNP in hospitals $(34.5\%)$, and problem solving inventory score (PS) was the highest factor predicting PSC of PMHNP in public health centers $(33.6\%)$. JS and PS accounted for $42.6\%$ in PSC of PMHNP in hospitals. and PS, JS, age, marital status, religion, and career accounted for $57.6\%$ in PSC of PMHNP in public health centers. In the light of these results. to gam the professional self-concept. nurses should be educated continuously through role modeling in clinical nursing and research. Also, nurse educators and administrators need to develop programs and policies to increase professional self-concept of nurses, particularly of community PMHNP.

Purpose : This study was conducted to investigate the extent to which the professional self concept between the psychiatric mental health nurse practitioner (PMHNP) and general nurse in psychiatric ward was comparable. The results were expected to provide basic data for developing the construct of professional self concept and making awareness of the importance of the program increasing professional self concept. Method : The subjects of this study were 227 PMHNP and 436 general nurse in psychiatric ward. The instruments used for this study were PSCNI by Arthur (1990), PSI by Heppner and Peterson(1982) and the index of work satisfaction by Slavitt et al.(1978). With the aid of the SAS, t-test. two-way ANOVA and stepwise multiple regression were conducted. Result : 1. The average item score of PSCNI of PMHNP was $2.82\pm0.27$. and that of general nurse was $2.66\pm0.27$. Statistically significant difference between two groups was found(p=0.0000) 2. There was statistically significant difference between two groups in the score of professional practice(p=0.0000), satisfaction(p=0.0024), leadersbip(p=0.0000) , flexibility(p=0.0000) and skill (p=0.0000). 3. Statistically significant differences between the two groups were observed in terms of age(p=0.0003), marital status(p=0.0001). education(p=0.0005), religion(p=-.0144), motive (P=-.0001), length of service as a nurse(p=0.0121), the length of service in psychiatric unit(p=0.0143). However there were no significant interaction effect with group and age, marital state. education, religion, motive, length of service as a nurse, length of service in psychiatric unit. 4. Job satisfaction (JS) and problem solving inventory score(PS) were found to be the highest factor predicting the professional self concept between the PMHNP and general nurse. JS and PS accounted for $43.4\%$ in the professional self concept of PMHNP, whereas PS, JS, age and religion accounted for $53\%$ in the professional self concept of general nurse in psychiatric ward. In conclusion, this study suggested that we need to develop programs and polices to increase the professional self concept of nurse, particularly of psychiatric mental health nurse practitioners.

Objectives : The object of this study was to investigate the relationship between coping strategies and perceived stress or pain discomfort in patients with chronic low back pain. 80 patients with chronic low back pain and 100 normal controls participated in this study. Methods: Global assessment of recent stress (GARS) scale and Stress Response Inventory (SRI) were used to measure perception for stressors and stress responses. Coping scale and pain discomfort scale were used to measure coping strategies and pain perception. Results : Scores of perceived stress related to work or job, interpersonal relationship, changes in relationship, sickness or illness and the total scores on the GARS scale were significantly higher in those with chronic low back pain than normal controls. Scores of the SRI fatigue subscale scored significantly higher in those with chronic low back pain than normal controls. No significant difference was found on total scores of the pain discomfort scale between those with chronic low back pain and normal controls. The patients with chronic low back pain scored significantly higher on planful problem solving and positive reappraisal than normal controls. In the patient group, pain perception had significant positive correlations with total scores of the SRI and scores of stress perception related to illness or injury. The extent of escape-avoidance showed significant negative correlations with age, whereas the extent of distancing or escape-avoidance had significant negative correlations with the level of education. Significant difference was also found in accepting responsibilities between male subjects and females. However, no significant correlations were found between coping strategies and perceived stressors, stress responses or pain perception. Conclusion : The results suggest that patients with chronic low back pain were more likely to use more active coping strategies than normal controls, though the former had more perception for stressors than the latter. It was also found that coping strategies used by the patients were associated with sociodemographic factors, but that they were not associated with perceived stressors, stress responses or pain perception.

The Pareto principle, also known as the 80-20 rule, states that roughly 80% of the effects come from 20% of the causes for many events including natural phenomena. It has been recognized as a golden rule in business with a wide application of such discovery like 20 percent of customers resulting in 80 percent of total sales. On the other hand, the Long Tail theory, pointing out that "the trivial many" produces more value than "the vital few," has gained popularity in recent times with a tremendous reduction of distribution and inventory costs through the development of ICT(Information and Communication Technology). This study started with a view to illuminating how these two primary business paradigms-Pareto principle and Long Tail theory-relates to the success of virtual knowledge collaboration. The importance of virtual knowledge collaboration is soaring in this era of globalization and virtualization transcending geographical and temporal constraints. Many previous studies on knowledge sharing have focused on the factors to affect knowledge sharing, seeking to boost individual knowledge sharing and resolve the social dilemma caused from the fact that rational individuals are likely to rather consume than contribute knowledge. Knowledge collaboration can be defined as the creation of knowledge by not only sharing knowledge, but also by transforming and integrating such knowledge. In this perspective of knowledge collaboration, the relative distribution of knowledge sharing among participants can count as much as the absolute amounts of individual knowledge sharing. In particular, whether the more contribution of the upper 20 percent of participants in knowledge sharing will enhance the efficiency of overall knowledge collaboration is an issue of interest. This study deals with the effect of this sort of knowledge sharing distribution on the efficiency of knowledge collaboration and is extended to reflect the work characteristics. All analyses were conducted based on actual data instead of self-reported questionnaire surveys. More specifically, we analyzed the collaborative behaviors of editors of 2,978 English Wikipedia featured articles, which are the best quality grade of articles in English Wikipedia. We adopted Pareto ratio, the ratio of the number of knowledge contribution of the upper 20 percent of participants to the total number of knowledge contribution made by the total participants of an article group, to examine the effect of Pareto principle. In addition, Gini coefficient, which represents the inequality of income among a group of people, was applied to reveal the effect of inequality of knowledge contribution. Hypotheses were set up based on the assumption that the higher ratio of knowledge contribution by more highly motivated participants will lead to the higher collaboration efficiency, but if the ratio gets too high, the collaboration efficiency will be exacerbated because overall informational diversity is threatened and knowledge contribution of less motivated participants is intimidated. Cox regression models were formulated for each of the focal variables-Pareto ratio and Gini coefficient-with seven control variables such as the number of editors involved in an article, the average time length between successive edits of an article, the number of sections a featured article has, etc. The dependent variable of the Cox models is the time spent from article initiation to promotion to the featured article level, indicating the efficiency of knowledge collaboration. To examine whether the effects of the focal variables vary depending on the characteristics of a group task, we classified 2,978 featured articles into two categories: Academic and Non-academic. Academic articles refer to at least one paper published at an SCI, SSCI, A&HCI, or SCIE journal. We assumed that academic articles are more complex, entail more information processing and problem solving, and thus require more skill variety and expertise. The analysis results indicate the followings; First, Pareto ratio and inequality of knowledge sharing relates in a curvilinear fashion to the collaboration efficiency in an online community, promoting it to an optimal point and undermining it thereafter. Second, the curvilinear effect of Pareto ratio and inequality of knowledge sharing on the collaboration efficiency is more sensitive with a more academic task in an online community.
