In order to estimate the pattern of medical care utilization and recognition for health factor among the inhabitants in Wan-do district which is located off the southern seashore from mainland Korea, household interview survey was performed from January 15 to 30, 1990 in Wan-do Gun area. The results observed were following: 1. Among the users of medical facilities 40.8% used public health facility as first contact facility. Lower the income level was and longer the residency duration was, the utilization rate of public health facilities was higher. By age groups and medical security status the utilization pattern was likely to disperse to local clinic and secondary contact medical resources. 2. Medical expense and access time were significantly different between primary contact and secondary contact medical resources. 3. Public health facility was recognized as the favoured institute having advantage of geographic and economic accessibility. 4. Statistically significant determinants in public health facility utilization among total medical service were the region, the medical expense, and the access time.

Purpose: This study identified sociodemographic characteristics, health status, health care utilization and related factors of Asian immigrant women in Korea. Methods: Data were collected from 465 immigrant women from China, Vietnam, the Philippines, and other Asian countries using standardized questionnaires. Descriptive statistics and $X^2$-test were performed utilizing SPSS version 17. A p-value <.05 was considered statistically significant. Results: Subjects had relatively good subjective health. The most prevalent conditions were, in order, anemia, gastrointestinal diseases, gynecological diseases, and depression. Subjects utilized mostly hospitals or clinics when sick. There were significant relationships between health care utilization and factors including residence, time since immigration and economic status. The rate of non-treatment in hospitals or clinics was 30.1% during the previous year, with significant relationships between non-treatment and factors including time since immigration and economic status. The major reasons for non-treatment were the burden of hospital expenses followed by communication difficulty. Conclusion: Public health efforts should be targeted to Asian immigrant women to improve their health status and support health care utilization.

This paper derives the upper and the lower bound of the mean cycle time and the mean service time of the class 6 and the class 4, within which the minimum utilization constrain of the class 4 is guaranteed. Also, derived are conditions under which the token bus network is stable or unstable. These bounds and stable conditions are represented in terms of the high priority token hold time, the token rotation time and the arrival rate and the total station number etc. This paper suggest a parameter tuning algorithm in a partially symmetric token bus network with two classes, which maximizes the token rotation time for a suitable high priority token hold time and at the same time meets the stability condition of the network, the real time constraint and the minimum utilization constraint of the class 4.

Objectives : To analyze medical service utilization and trends among the elderly in the last year of life. Method : The subjects of this study were People that had died at the age sixty-five and above between January $1^{st}$ and June $30^{th}$ 2000 The names of the deceased and their dates of death were collected from the data of the funeral-expenses-receivers of the National Health Insurance Corporation (NHIC). This data was merged with that of the individual medical expenses of the NHIC. Results : In the first half of 2000, 84.2% of the funeral-expenses-receivers (53,063) utilized medical services during the year prior to their death; 51.0% (27,042) were female and 49.0% (26,021) male. In the last twelve months of life, the medical fees, the number of days receiving medical services and the number of days receiving medicine were 3,107,935 Won, 47.88 and 153.21, respectively, for each person. As the age of the groups increased, the level of medical service utilization decreased; the change was more obvious in female group. The level of medical service utilization during the twelve months prior to death drastically increased around the time of death. Conclusions : This study, from an analysis of the level of medical service utilization prior to death, shows a concentrated volume of medical services during a certain time period prior to death.

본 연구는 수도권 농촌지역인 여주 지역의 토지이용 변화, 생활실태의 변화, 생활공간의 입지변화를 살펴 급격하게 변화하고 있는 생활공간의 지역성을 규명하였다. 여주 지역의 토지이용은 농촌 토지이용의 감소와 도시적 토지이용의 완만한 증가를 보인다. 완만한 속도의 도시화를 나타내는 기능으로서 관광농업이 나타나고 농외 겸업 활동이 비교적 활성화되고 있다. 여주지역 육로교통(고속도로통과)의 발달은 생활공간상의 입지이동에 큰 영향을 주었다. 수도권 외곽의 농촌이던 이곳은 도시화가 더딘 곳이었지만, 곧 전철 등의 개통 등 교통의 발달과 함께 도시화가 가속화될 지역이라 할 수 있다. 치밀한 도시계획이 수행될 때, 쾌적한 도시 주거환경 지역으로 변모할 것이 예상된다.

Purpose: This study was conducted to examine whether the level of classification for long-term care service under longterm care insurance reflects resource utilization level for residents in nursing homes. Methods: From 2 long-term care facilities, the researchers selected 95 participants and identified description and time of care services provided by nurses, certified caregivers, physical therapists and social workers during a 24-hr-period. Results: Resource utilization level was: 281.04 for level 1, 301.05 for level 2 and 270.87 for level 3. Resource utilization was not correlated with level. Differences in resource utilization within the same level were similar with the coefficient of variance, 22.7-27.1%. Physical function was the most influential factor on long-term care scores (r=.88, p<.001). The level for long-term care service did not reflect differences in resource utilization level of residents on long-term care insurance. Conclusion: The results of this study indicate that present grading for long-term care service needs to be reconsidered. Further study is needed to adjust the long-term care classification system to reflect the level of resource utilization for care recipients on the long-term care insurance.

A new dynamic scheduling algorithm is proposed for CAN-based real-time system in this paper. The proposed algorithm is extended from an existing EDS(Earliest Deadline Scheduling) approach having a solution to the priority inversion. Using the proposed algorithm, the available bandwidth of network media can be checked dynamically, and consequently arbitration delay causing the miss of deadline can be avoided. Also, non-real time messages can be processed with their bandwidth allocation. Full network utilization and real-time transmission feasibility can be achieved through the algorithm. To evaluate the performance of algorithm, two simulation tests are performed. The first one is transmission data measurement per minute for periodic messages and the second one is feasibility in the system with both periodic messages and non-real time message.

This paper analyses the real-time performance of Ethernet based intranet whether it is applicable to the real-time network. Unpredictability of transmission delay by collision-delay-retransmission mechanism in CAMA/CD(Carrier Sense Multiple Access with Collision Detect) of Ethernet is the major reason making hard to apply to real-time system. Both retransmission mechanism of TCP(Transmission Control Protocol) for reliability and sliding windows algorithm for high utilization make hard to predict transmission delay. Because real-time control network require fast responsibility and bustle of short-periodic messages, global-clock for collision avoidance and UDP(User Datagram Protocol) for high utilization of network are used. The mathematical models for time-delay that can be occured between ...

The IEEE 802.15.4 standard not only provides a maximum of seven guaranteed time slots (GTSs) for allocation within a superframe to support time-critical traffic, but also achieves ultralow complexity, cost, and power in low-rate and short-distance wireless personal area networks (WPANs). Real-time wireless body area sensor networks (WBASNs), as a special purpose WPAN, can perfectly use the IEEE 802. 15. 4 standard for its wireless connection. In this paper, we propose an adaptive GTS allocation scheme for real-time WBASN data transmissions with different priorities in consideration of low latency, fairness, and bandwidth utilization. The proposed GTS allocation scheme combines a weight-based priority assignment algorithm with an innovative starvation avoidance scheme. Simulation results show that the proposed method significantly outperforms the existing GTS implementation for the traditional IEEE 802.15.4 in terms of average delay, contention free period bandwidth utilization, and fairness.

This study investigated the internship experiences of female college students who have participated in consumer counseling programs. The factors that determine interns' counseling time and interns' level of satisfaction with the programs were examined. Major results of this study are summarized in the following. First, interns' time spent on counseling consumers was the longest for the program at the Korean Consumer Protection Board, followed by the programs at consumer agencies and firms. The time spent on counseling by interns was shorter when there was l) a larger number of employees; 2) a smaller proportion of female employees: 3) a larger number of counseling rooms and a higher the frequency of counseling at the agency; and 4) a lower evaluation on the work performance of the counseling agency and the employees. Second, the level of utilization of interns was the highest in consumer agencies, followed by the Korean Consumer Protection Board. When all employees were female and the evaluated level of work performance of the counseling agency and employees was high, the level of intern utilization was also high. Third, the evaluated level of work performance was the highest at the Korean Consumer Protection Board, and interns' satisfaction with the internship program was the highest with the consumer agencies and the Korean Consumer Protection Board. Fourth, interns were highly satisfied with the program when the level of intern utilization was high and the agency's operation was evaluated as good.
