The study was originated from recognition that project participants' satisfaction should be Improved to raise project performance and to make progress of a successful project since the above dissatisfaction was operated as a danger factor of the project. The study selected one large-scale sample project and attempted measuring characteristics of the project, participants' satisfaction and project performance with the whole project participants. The study analyzed correlations between individual level (team members) and group level (development team), and examined what effect a sub project manager under complicated hierarchical organization of the large-scale project, namely PL (project leader)'s leadership style had on each individual project participant's satisfaction and what effect project uncertainty in organization/technology environment had on project participants' satisfaction and project performance. The study verified that development team (group) had an effect on team member (individual)-level project participants' satisfaction by disclosing that there was a significant dispersion among groups within project participants' satisfaction by each individual. It is analyzed that it is necessary to make improvement through approach by each pertinent team to raise individual-level project participants' satisfaction. The study also verified PL's ideal leadership under strict methodology and hierarchical control of the large-scale project. Based on the verification of the hypotheses, the results of the analysis were produced as follows. First, the development team affects the satisfaction level that an individual has when he/she participates in a project. This suggests that the satisfaction with project participation should be improved at the team level. In addition, the project management style and leadership orientation of the manager of a sub project who is mostly affected by the team proved to have a direct influence on the satisfaction with project participation and project performances. Second, both the performance-oriented leadership and the relationship-oriented leadership of the PL of the development team were verified to have a significant effect on the satisfaction of the team members associated with project participation. In other words, when the team members recognize that the PL of the development team shows both the performance-oriented leadership and the relationship-oriented leadership, their satisfaction with project participation increases accordingly. Third, it was verified that the uncertainty of the organizational environment significantly affects the satisfaction level when the PL of the development team exerts a relationship-oriented and performance-oriented leadership. The higher the uncertainty of the organizational environment is, the more the satisfaction with project participation decreases whereas the relationship-oriented leadership has a more positive effect on the satisfaction than the performance-oriented leadership style. Fourth, when the PL of the development team exerts the relationship-related and performance-related leadership, the uncertainty of the technological environment has a significant influence on the satisfaction level. The higher the uncertainty of the technological environment is, the more the satisfaction with project participation decreases whereas the performance-oriented leadership has a more positive effect on the satisfaction than the relationship-oriented leadership style. The result of the research on the uncertainty of the project environment suggests that when the development team leader exerts a relationship-oriented and performance-oriented leadership style, the uncertainty of the organizational environment has a significant effect on the satisfaction with project participation; the higher the uncertainty of the organizational environment, the more the satisfaction level decreases, and the relationship-oriented leadership style affects the satisfaction level more positively than the performance-oriented leadership style. In addition, when the development team leader displays a relationship-oriented and performance-oriented leadership style, the uncertainty of the technological environment has a significant effect on the satisfaction with project participation; the higher the uncertainty of the technological environment. the more the satisfaction level decreases. The performance-oriented leadership style as well affects the satisfaction level more positively than the relationship-oriented leadership style. Based on the above results, the research provides the following implications when handling multiple concurrent projects. First, the satisfaction with the participation in the multiple concurrent projects needs to be enhanced at the team (group) level. Second. the manager of the project team, particularly the middle managers should have both a performance-oriented and relationship (task and human)-oriented attitude and exert a consolidated leadership in order to improve the satisfaction of team members with project participation and their performances. Third, as the uncertainty factor of the technological and organizational environment among the characteristics factors of the project has room for methodological improvement depending on one's effort even though there are some complications, we need to continuously prevent and control the risks resulting from the uncertainties of the technological and organizational environment of the project in order to enhance the satisfaction of project participation and project performances. Fourth, the performance (task)-oriented leadership is required when there is uncertainty in a technological environment while the relationship (human)-oriented leadership is required when there is uncertainty in an organizational environment. This research has the following limitations. First, this research intended to select one large-sized sample project and measure the project characteristics, the satisfaction of all the participants associated with project participation, and their performances. Therefore, it is inappropriate to generalize and apply the result of this result onto other numerous projects. Second, as this case study entailed a survey to measure the characteristics factors and performance of the project, since the result value was based on the perception of project team members, the data may have insufficient objectivity. Third, though this research targeted on all the project participants, some development teams did not provide sufficient data and questionnaires were collected from some specific development teams among the 23 development teams, causing a significant deviation in the response rate among the development teams. Therefore, we need to continuously conduct the follow-up researches making comparisons among the multiple projects, and centering on the characteristics factors of the project and its satisfaction level.

Screening of estrogenic activity on dichloro diphenyl trichloroethane (DDT), dichloro diphenyl dichloro ethylene (DDE), dieldrin, heptachlor, aldrin, chlordane, lindane, polybrominated diphenyl ethers (PBDE) and parabens was compared using Organization for Economic Cooperation and Development (OECD) test guideline 455 (TG455). The estrogenic activity of DDT was 58,000-fold ($PC_{50}$, $1.67{\times}10^{-6}$ M) less than $17{\beta}$-estradiol($E_2$) ($PC_{50}$, $2.88{\times}10^{-11}$ M) but DDE, dieldrin, heptachlor, aldrin, chlordane, lindane and PBDE did not show any estrogenic activity in this assay system. In the case of paraben compounds, the rank of relative transcriptional activation (logRTA) was butyl paraben -1.63752 ($PC_{50}$, $1.25{\times}10^{-7}$ M) > isobutyl paraben -2.34008 ($PC_{50}$, $6.3{\times}10^{-7}$ M) > ethyl paraben -2.64016 ($PC_{50}$, $1.26{\times}10^{-6}$ M) > isopropyl paraben -2.73993 ($PC_{50}$, $1.58{\times}10^{-6}$ M) > propyl paraben -2.84164 ($PC_{50}$, $2.0{\times}10^{-6}$ M). Our data suggest that OECD test guideline TG455 may be useful as a screening tool for potential endocrine disruptors.

Purpose: This study was designed to analyze effects of learning organization on organizational commitment based on the MBTI personality type. Methods: The participants were 521 nurses working in the 4 general hospitals located in Seoul, Incheon and Kyunggido. The data were collected by self-reporting questionnaires. The data were analyzed using SAS program for descriptive and Stepwise multiple regression analysis. Results: The most frequent identified personality type was ISTJ and the least identified personal types was ENFJ. It is differ to recognize the learning organization according to personality type. In an aspect of organizational commitment, the statistically significant learning organizational factors according to nurse's MBTI personality type is revealed slightly different. In other word, Shared Vision is a statistically significant factor in ISTJ, ISTP, ISFP, ESTJ and ESFJ. System Thinking is a statistically significant factor in ISFJ. Team learning is a statistically significant factor in ESTP and ISTP. Mental Model is a statistically significant factor in ISTP. Conclusion: As our results, the effects of learning organization on organizational commitment were different according to the nurse's MBTI personality type. So these results will be used to develop the more effective strategies to enhance nurse's organizational commitment using construction of learning organization.

This study examines organizational qualities such as vision, mission, teamwork, fairness, and empowerment and their effects on organizational members. As a result of analysis, these qualities are identified to affect member satisfaction, but not to affect job involvement. Member satisfaction affects job satisfaction, and this relationship retains indirect influence through an increase in member satisfaction. Further, improved member satisfaction and job involvement are found to affect organizational commitment. These results are derived from complete enumeration on members of an organization where particular traits such as member position, job classification, and the privity of contract are intermixed. In case where research is conducted on the aforementioned traits separately, different results would be anticipated depending on each trait. The implications of this study are as follows. First, clear-cut organizational vision and mission established by the top management of an organization prevent confusion amongst its members, and thus have the highest level of effect on member satisfaction. Second, teamwork in reference to the. relationship amongst team members of a work group and goal awareness improves member satisfaction. Third, autonomy for job performance and related empowerment improve member satisfaction. Last, fairness in wages and promotion affects member satisfaction. Therefore, internal qualities of an organization perceived by its members have a higher degree of influence over external qualities including compensation and promotion on the members. In addition, these internal qualities indirectly affect job involvement through an increase in member satisfaction, and, in turn, member satisfaction and job involvement affect organizational commitment of the members. In case of member satisfaction, not only does it affect organizational commitment of the members of an organization directly, but also affects organizational commitment indirectly through job involvement. This study is conducted with only one hospital in consideration, and thus its findings may not be generalized for every medical organization. However, this study retains distinct attributes of complete. enumeration, and the precedence of each variable is closely investigated.

The digital economy era is a knowledge-based society. Many organizations have been establishing KMS (Knowledge Management System), and there are no exceptions in military ones. In this study, we analyze the influencing factors for KMS utilization in a military organization, which is a specialized one. For this purpose, we investigate the current status of KMS of ROKAF (Republic Of Korea Air Force), derive problems and issues, and try to find out solutions for the KMS utilization in military organizations by analyzing a survey. At first, we derive three characteristics of the military organization that affect the knowledge sharing : formalization of organization, trust of organizational culture, and top management's will. And we verified that the users, who recognize that the top management has the will for the knowledge sharing, have high recognition for the knowledge sharing and utilize KMS more than others. This study shows that it is very important for the top management to participate in the knowledge sharing voluntarily especially in the military organization.

Purpose - The increase in organizational citizenship behavior is important in that it creates a cooperative atmosphere within the organization. Proving how OCB toward coworkers changes in negative leadership situations such as abusive supervision is a new research stream. Therefore, this study examines the main effects of the supervisor's abusive supervision on OCB of subordinates for coworkers, and then attempts to clarify that the perceived LMX differentiation of team members play a moderating role. Research design, data, and methodology - First, we examine the effects of the supervisor's abusive supervision on OCB of subordinates in the team toward colleagues. Second, the degree of perceived LMX differentiation is measured to verify the moderating effect of abusive supervision on OCB toward coworkers. Result - Hypothesis 1 is that abusive supervision has a negative effect on coworkers' OCB. Hypotheses 2-1, 2-2, and 2-3 test the moderating effect of perceived LMX differentiation, and the relationship between abusive supervision and coworkers' OCB will change according to the perceived degree of LMX differentiation. Conclusion - It is significant in that the scope of abusive supervision research has been expanded through the team level moderator of perceived LMX differentiation, away from the research on abusive supervision that was mainly discussed at the level of dyadic relationship (between the supervisor and the one subordinate).

This study examined the effects of a physical therapy program on quality of life (QOL), and neck and shoulder disability in head and neck cancer patients. The program included neck and shoulder range of motion (ROM) exercises, massage, progressive strengthening exercises, and stretching exercises. Sixteen patients who were assigned to an experimental group performed physical therapy for 40 minutes three times a week for eight weeks. Fifteen other patients were assigned to a control group who did not performed the physical therapy program. The European organization for research and treatment of cancer (EORTC QLQ-C30) and head and neck (EORTC QLQ-H&N) instruments, and the Neck Disability Index (NDI) were assessed before and after the rehabilitation program. The 40-minute program consisted of a 10-minute ROM exercise for the neck and shoulder, a 10-minute massage and 15-minute of progressive resistance exercises, followed by a five-minute stretching exercises. Statistically significant differences were noted for changes in global health, physical function in the EORTC QLQ-C30 and cancer related symptoms in the EORTC QLQ-H&N35 (p<.05). The NDI also showed significant differences (p<.05). Physical therapy may therefore benefit the physical aspects and QOL and improve neck and shoulder disability in patients with head and neck cancer.
