본 논문에서는 분산 객체 관리의 편의성을 제공하고, 고장 발생시에도 안정된 서비스를 가능케 하는 고장포용 객체그룹(Fault-Tolerant Object Group, FTOG) 프레임워크를 제안한다. FTOG 프레임워크는 서비스 우선순위와 체크포인트 방법을 이용하여 두 가지의 고장 회복 방안을 제공하며 퍼지 기반의 부하 추론 과정을 통한 부하 분산을 수행하여 서비스 실행에서의 효율성을 높인다. 또한 가상의 홈네트워크 환경을 구성하고 FTOG 프레임워크를 적용하여 시뮬레이션을 통해 분산되어 있는 객체들의 관리 및 부하 분산 등 본 모델의 안정성 및 신뢰성을 검증하였다.

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.

The purpose of this research is to identify causalities among service quality, service value, customer satisfaction and customer loyalty and to compare the causalities between in-patients and out-patients. A multi-group structural equation model was used to test the hypothesis of conceptual model. Empirical results indicate that two factors such as assurance and empathy have direct impact on service value and customer satisfaction in both the patients. In the results of multi-group comparison test, however, the path coefficients from service value to customer loyalty and from customer satisfaction to customer loyalty were different across the two groups. In out-patients, customer loyalty is more positively related with service value. In in-patients, customer loyalty is more positively related with customer satisfaction. It is proven that service quality influences customer loyalty. Therefore To compete successfully in today's volatile & competitive medical markets, the hospital needs to manage the service quality, considering the type of patients.

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.

Purpose: The purpose of this study was to evaluate the effectiveness of case management for patients with hypertension on their health status and medical service utilization. Methods: This study was a secondary analysis of data collected for a larger study of chronic disease management in 2008 using the National Health Insurance Corporation database. A total of 12,944 patients who received case management for hypertension were included in this analysis. The subjects of case management were classified into subgroups, namely, over-use, under-use, and non-use groups according to the amount of medical service utilization. To compare the medical service utilization, a control group was selected randomly. The data were analyzed through descriptive statistics, McNemar test, and ANOVA. Results: All the subgroups displayed significant differences in blood pressure, self-management, social support, and their characteristics of medical service utilization. The total medical expense of the under-use and non-use groups increased after case management. However, there was no decrease in the medical expense of the over-use group. Conclusion: This finding suggests that there is a need to re-examine why patients overuse medical services and to supplement specific strategies for encouraging appropriate medical service utilization, and enhancing case management efforts for the over-use group.

Most of the prior studies on the servitization of manufacturing companies have been actively studied, focusing on the performance and cases of servitization at the single company level. According to the results, most of the servitization at the single company level has been expanded based on the relevance of the company's core products. However, the form of companies that form a large axis of the Korean economy is a large-scale business group, and these business groups incorporate service affiliates for various purposes, so they show different characteristics from that of a single corporate. In addition, since the purpose of forming a business group is different for each business group, the service relevance between affiliates within the business group is different. Therefore, this study aims to examine the effect of service relevance between affiliates within a business group on the management performance of each business group. To this end, an empirical analysis will be conducted using panel data for 10 years from 2011 to 2020 for a total of 98 affiliates listed on KOSPI and KOSDAQ of 9 domestic business groups. Based on these results, the direction for improving management performance and establishing future servitization strategies for large business groups in Korea will be expected to be made.
