Purpose: This paper studies the influence of the case-management program on the change of blood sugar, lifestyle, and knowledge level of diabetes mellitus (DM) for medium-sized-enterprise employees suffering from DM. Method: Subjects, divided into experimental and control groups, are 59 workers with FBS higher than 126mg/$d{\ell}$ or under DM medication treatment in the medium-sized enterprises, being managed by two distinct university hospital group occupational health management service teams. The case management program for DM patients consists of 6 different processes in which each subject is treated. Result: FBS decreased in the experimental group after the program, while that of the control group increased significantly. In the experimental group, the amount of smoking, the frequency of drinking and the amount of drinking per week decreased. Also, the knowledge level for DM and the change of nutrition management showed significant increase. In the control group, the amount of smoking increased and the frequency of drinking, the amount of drinking and nutrition level did not change significantly. And the knowledge level for DM decreased. Conclusion: We expect that taking this case management program for DM management may significantly improve diabetic patients' overall health.

To investigate the actual management condition of group homes for the elderly and their living environment, four group homes and 26 elderly people living in the group home were surveyed. As the results, the relationships between the administrator and the elderly were acceptable, but the group homes seem suffer from insufficient administrative supports. The most required service in the group homes was a conversational partner service. Moreover, the most satisfactory point for the elderly living in group homes was the settlement of food, clothing, and housing. The unsatisfactory things were the service related to medical, leisure, and house work and an invasion of their private life. The resident elderly in group homes were fully satisfied with their living environment including the relationship with the manager and the people in the facility. They, however, do not have much chance to make an exchange with their neighbor. Overall, the elderly want to stay continuously in the group homes where they are living current.

The changing structure of organization and the increasing diversity of business have forced organizations to have abilities to coordinate dispersed business activities. They have required cooperation and coordination among the functional units in the organization which should involve group decision-making processes. Although many group decision-making support tools and methods have been introduced to enable the collaborative process of group decision-making, they often lack the features supporting the dynamic complexity issue frequently occurring at group decision-making processes. This results in cognitive unfit between the group decision-making tasks and their supporting tools, bringing about mixed results in their effects on group decision-making. This study proposes system dynamics modeling as a group decision-making support tool to deal with the group decision -making tasks having properties of dynamic complexity in terms of cognitive fit theory.

Purpose: The purpose of this study was to examine the effects of education regarding postoperative pain management provided for nurses as well as patients on related factors of pain management, including nurses' knowledge and attitude of postoperative pain, and the level of pain that patients felt after surgery. Method: A quasi-experimental research design was used in this research. Twenty-one nurses currently working in general surgery units and 32 patients who were taking on abdominal surgery in A university hospital were participated in this study. The three week-educational program of postoperative pain management including lecture, quiz, poster and discussion was provided for nurse participants. The postoperative pain management education for each patient was provided one day before his/her own operation for 20 minutes with the pamphlet developed by researchers. For assessing the effects, nurses' knowledge and attitude about pain management, patients' postoperative pain, pain control barriers, and satisfaction of pain management were measured. Results: The nurses' knowledge about pain management and the patients' satisfaction of pain management in the experimental group were higher than in the control group. The patients' postoperative pain in the experimental group was lower than in the control group. Conclusion: With the above results, the postoperative pain management education could be an effective nursing intervention for pain management of patients who were taking surgery.

Objectives: This study aims to examine if the follow-up management service by National Health Insurance (NHI) for person at health risk leads to significant modification of the lifestyle and change of health status. Methods: Of persons who underwent health screening and were classified as having health risks after periodic health screening by NHI in 2003, persons who took the follow-up management service were selected as case group and persons who took no service were selected as control group. The DW database of NHI was used to explore the effect of the follow-up management service on the modification of health status and lifestyle. Chi-square tests were conducted with SAS 9.1 to examine the differences of health promotion effect between case vs. control group. Results: It was shown that of lifestyle behaviors, only exercise was significantly improved for case group compared with control group as the effect of the follow-up management service by NHI (2.98%p) (p<.0001). Further, morbidity rate for control group was 2% higher than that of case group (p <.0001), which indicates that persons who received the follow-up management service better maintained their health significantly than persons who did not. Conclusions: The present study shows that the appropriate follow-up management services need to be provided for maximizing potential effect of periodic health screening by NHI.

In recent years, mobile ad-hoc networks have received a great deal of attention in both academia and industry to provide anytime-anywhere networking services. As wireless networks are rapidly deployed, the security of wireless environment will be mandatory. In this paper, we describe a group key management architecture and key agreement protocols for secure communication in mobile ad-hoc wireless networks (MANETs) overseen by unmanned aerial vehicles (UAVs). We use implicitly certified public keys method, which alleviates the certificate overhead and improves computational efficiency. The architecture uses a two-layered key management approach where the group of nodes is divided into: 1) Cell groups consisting of ground nodes and 2) control groups consisting of cell group managers. The chief benefit of this approach is that the effects of a membership change are restricted to the single cell group.

This study focused on working women's perceptions of social attractiveness and their appearance management behavior. Social attractiveness is defined as individuals' achieved attractiveness which can be expressed through social expressive power or social skills rather than innate physical appearance. This study was empirically conducted through questionnaires distributed to 200 working women in South Korea. According to the results, the participants recognized four factors constituting social attractiveness: physical appearance management, business manners, social skills, and sexual attractiveness. When they were asked to assess themselves on the same measures, these characteristics were further classified into six factors: business manners, feminine attractiveness, fashion sense, sociability, communication skills, and active appearance management. Their self-perceived social attractiveness was found to be influenced by all these factors in the order of feminine attractiveness, business manners, sociability, communication skills. Based on the self-presentation tendencies, the participants were classified into various groups, including the passive management group, daily life-oriented management group, work-oriented management group, neutral group, and active management group. The relative importance of the social attractiveness components was found to differ by group, although working women in all groups rated weight management higher than appearance management behavior. This study has implications in that it facilitates an understanding of the concept of social attractiveness and also provides a foundation base in terms of beauty consulting and marketing for working women to improve their social attractiveness.
