The geographical distribution of active physicians who graduated from medical schools before 1985 were studied. Those who had emigrated, hold non-medical jobs, are in the military service, or work as public health physicians and resident staff were excluded from the study. A total of 27,728 physicians were analyzed. Our studies have shown a relationship between the location of the medical schools from the which the physicians have graduated and the geographical regions in which they practice. A statistically significant number of physicians are working near the medical colleges from which they have graduated. That is, those who had graduated from medical schools located in the southern area of the country are presently working in the same region. This relationship was shown to be especially significant for older physicians and female doctors, who work around the area of the medical colleges from which they graduated.

An electronic watt-hour meter with high-precision measurement technology can provide many valuable metering data of a real-time system measurements, such as per-phase voltage, ampere, active power, reactive power, apparent power, power factor, and system frequency. Also many of accumulated metering data such as active energy, reactive energy, apparent energy, and load profile can be gettable from an electronic watt-hour meter[1]. This paper presents an approach of the small-sized AMR (Automatic Meter Reading) that provides customers with a very valuable electrical service. This AMR service transmits lots of a valuable metering data by using ZigBee communication module, so that users resided in their premises can use the information to audit a power quality and improve their electrical conditions by using the PQ monitoring device equipped with ZigBee receiver. This PQ monitoring device shows metering data on LCD and transmits to the PC through an internal network. Also, the device can keep the valuable meter data into a built-in non-volatile memory. The final goal of this paper is to better understand the power quality of electrical systems and offer the power qualify information for the convenience of all power consumers.

Since the world wide web, simple and convenient tool, has proposed, the Internet became the most simple network resource which provide many informations of the world. Furthermore, various methodologies are developed to support the dynamic service such as 3D View web service. We will propose the volume rendering view program that interactively visualize the 3D data on the web. The 3D Data is obtained by stacking the 2D images along the z-direction. We also employ the COM based OCX control which is a kind of Active component. This web program will contribute the diagnosis of the diseases through the 3D visualization and image analysis functions at remote places.

Purpose: The purpose of this study is to identify clubhouses general characteristics, core services, funding sources and costs in Korean Clubhouse Model, and to compare with Korean and international clubhouses. We explored the annual budget, cost per member, and cost per visit for 1 year. Methods: The data were collected from 14 Korean clubhouses and analyzed using descriptive statistics and Spearman's rank correlation with the SPSS 14.0 program. Results: The average of clubhouse operating period was 8.2 years. There were an average of 40.4 active members; among them, 84.1% were schizophrenia. In addition, there were an average of 5.8 staff and 15.3 services in each clubhouse. Cost estimates were as follows: annual budget (excluding housing) $223.633, cost per member $5,704, and cost per visit $21.35. There were significant difference among the annual budget, number of staff, number of service, and active members, but hours of Work-Ordered Day and social activities hours were not statistically significant. Conclusion: Findings provide a more understanding of operations, programs, and costs of Korean clubhouses.

We investigated the user behavior of the theme display provided by the public libraries as an active information service. Specifically, we wanted to study the library patrons' library use behavior and perception. There were in-depth interviews with seven librarians and eight patrons to develop a set of research questions and the questionnaire. We conducted the survey with 232 patrons then the statistical analysis. The analysis result revealed that the theme display helped the patrons' wider use of the library resources and also positively affected patrons' perception on the librarians as well as the evaluation of the library services. Based on the findings, we recommended the active incorporation of the theme display within the limitation of the libraries' facility and patrons' interests.

Mobile IP has been designed only to maintain communication as they move form place to place, so it doesn't guarantee Quality of Service(QoS). QoS in mobile IP is important to provide multimedia and real-time applications services in mobile, and it is closely related to handoff delay. Therefore, handoff delay problem is actively studied to guarantee QoS as a main issue in mobile IP research area Next generation Mobile IPv6 resolve this problem somewhat, triangle problem for first packet and handoff delay still remain. In this paper, we suggest SNMP Information-based routing that adds keyword management method to Information-based routing in active network in order to resolve such a problem, and then suggest QoS controlled handoff based on SNMP Information-Based routing. After modeling of suggested method and existing handoff method simulations we carried out with NS-2 for performance evaluation. The results of simulations show the some improvement on handoff delay, and therefore on QoS improvement.

Objectives: The purpose of this study is to analyze basic data on socio - demographic characteristics, occupational careers, and desire for employment of job seekers in their Fifties and Sixties using a portal site. Methods: For this research, secondary data were collected by the researcher from 704 job seekers and were statistically analyzed using the SPSS package. Results: The results of the analysis are as follows: Most job seekers want a job that suits their competence and career trajectory, but the reality is that as their age increases, jobs suitable for those in their fifties and sixties are hard to find; thus these job seekers accept simple labor or functional jobs. Conclusions: Differences were found in work conditions such as occupation level, job position, total career years, desired employment type, and expected salary depending on socio - demographic variables. Consequently, improvements should be made for various job searching paths for older adults as well as increasing the accessibility of job searching information.
