  • Two macrolide-lincosamide-streptogramin B (MLS) antibiotic resistance genes, one expressed inducibly and the other expressed constitutively were recognized from a single Staphylococcus aureus DH1 strain. The inducible MLS resistance gene was isolated and cloned from the R-plasmid pDE1(7.4kb) and the constitutive gene was from chromosomal DNA. Base sequence of the inducible MLS resistance gene (1.2kb) was determined and found as same that of pE194. The restriction map of the cloned constitutive MLS resistance gene was compared with that of the inducible gene. Two genes have same restriction map except leader region. In the constitutive gene there is no leader region which is doing major role in inducible expression.

  • Purpose: This study was conducted in commemoration of the 40th Anniversary of the Korean Academy of Community Health Nursing [KACHN]. Methods: Primary and secondary sources were collected and analyzed to show changes that KACHN has experienced. Results: In the 1970s it made the annual meeting regular and began research presentation. In the1980s regular symposiums were activated and as a result the academy could publish its own journal from 1989. In the 1990s the boards were selected from locals by turns and lots of papers and teaching materials were produced from collaborate researches of the members. In the 2000s, the journal was selected by the National Research Foundation in Korea and the academy began regular Korea-Japan Community Health Nursing Conference and hosted the 5th ICCHNR. Conclusion: In spite of great development, KACHN has new challenges. The number of members has increased so much that there are a few academies specialized in some fields of community health nursing. They have made the members' interest and loyalty weaker than during the pioneer days. KACHN should take the new role as a leader of international community health nursing research as well as the old role as a leader of Korean community health nursing research.

  • Work engagement and job burnout are crucial problems in Korea, particularly in the business environment, and they also indicate people's motivation. Online-based teams in e-business also have these issues. Especially the role of the leader in this new type of teams is more crucial for members' motivation, behavior, and performance. Contingency leadership theories posit that different situations need different traits or behaviors of a leader. For an online-based team, which is internet-based team in e-business, a leader should use specific communication strategies to enhance a team's performance and members' motivation. In an online-based team and an offline-based team, the ways in which leaders motivate members will be different. This paper suggests particular communicative strategies for leaders of online situations. Online-based team members communicate using mobile phones or IT tools, and leaders mayinfluences members in virtual meetings. Moreover, online-based leadership needs to be more entrepreneurial and risk encouraging, and less conservative than offline-based leadership. In addition, online-based leadership should be energetic, decisive, adaptable, and inspiring, and furtherutilize communication tools such as being more gregarious/talkative, assertiveness, linguistic diversity and affect. This paper explains the roles of communicative elements such as coordination, expression, direction-giving/uncertainty reduction, empathy, meaning-making, satisfaction, and competence to decrease job burnout and to increase work engagement. The purpose of this study is to suggest communication strategies' differentiated influences on work engagement and job burnout in an online-based team.

  • 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.

  • THis study examines a contingency relationship between task uncertainty and structure of project teams in conjunction with the leader-member communication patterns. Multivariate analyses are used to analyze the data from 63 R & D project teams of research laboratory in a large manufacturing corporation. Major findings for this study can be summarized as follows. First, project teams with an organic structure are found to yield high performance when task uncertainty is high, while project teams with a mechanistic structure achieve high performance when their tasks are relatively certain. Second, patterns of leader-member comunication are significantly associated with both task uncertainty and structural characteristics of project teams. This implies that leaders of project teams communicate with their members in more conslutative manner when their tasks are uncertain or when their team structure exhibits organic characteristics. Finally, task uncertainty playus a significant moderating role in the relationship between consultative communication patterns and performance of project teams. Based upon these findings, this study offers several theoretical, practical, and methodological implications.

  • This purpose of this study is to examine the relationships of ethical leader and ethics management system with employees's organizational citizenship behavior and the mechanism underlying these relationships. A questionnaire survey was conducted involving 1,035 full-time employees from large and medium industries in Daegu and Gyeong-buk provinces. Regression analysis was used to test the hypotheses. The results showed that both of ethical leader and ethics management system were positively related with employees's organizational citizenship behavior. As expected, these relationships were mediated by organization-oriented ethical climate and social responsibility-oriented ethical climate respectively. The findings of this study are as followings: First, employees tend to show their pro-social behavior when they perceive their leaders act ethically and ethics management is well institutionalized. Second, building up the organization-oriented ethical climate and social responsibility-oriented ethical climate can be a powerful strategy to enhance employees's organizational citizenship behavior.

  • This exploratory study reports how teacher-librarians perceive their roles as practitioners in school library media programs. Conducted within the framework of qualitative research, the study employed a focus group interview (Morgan 1997) with five teacher-librarians at elementary school level in Seoul. The findings suggest: (1) the roles of teacher-librarians are influenced a great deal by many factors in educational systems; (2) there is no consensus on how to define and perform their role as teachers; (3) there seems to be increasing emphasis on their program administrator's role; (4) there is no consensus on prioritizing the five roles suggested by the AASL (2009), but all the participants agreed that the leader's role is most crucial for the success of pursuing the rest of the roles, and (5) there seems to be no clear boundaries as teacher-librarians perform their roles. Putting all the results together, the researcher was able to conclude that teacher-librarians are frequently asked to be flexible and negotiable and have great burden in the affective, cognitive, and physical realm for the roles imposed and expected of them.

  • Information technology leadership roles have undergone fundamental change over the past decade. Despite increase interest in recent years, little empirical research on Information Technology has been done. This paper suggests results from a survey in Korea on Information Technology. The survey collected data on general leadership roles such as information roles, decisional role and interpersonal role, as well as on specific Information Technology leadership roles such as planning leader, R&D manager, general manager, chief operating strategist. The role of a change leader is positively influenced by the number of years, the extent of strategic responsibility and the organization's revenue while it is negatively influenced by the number of years in the current position. R&D manager can be predicted by strategic responsibility and chief executive's IT use, Manager can be predicted by the extent of strategic responsibility. Although several significant predictors of Information Technology leadership roles were identified, the more signigicant study should continue in the future.

  • This research attempts to carry an empirical study on women leaders' gender-related leadership styles and relationship between job satisfaction and organizational commitment. For these purpose, this study built two hypotheses based on literature review and tested them using the survey method of 1,172 female workers in sales departments of the K company. The results of this study show that both the androgynous gender role and the masculine gender role are superior to the feminine gender role in employees' job satisfaction and organizational commitment level. But there isn't significant level difference in job satisfaction and organizational commitment between androgynous gender role and the masculine gender role.
