Purposes: This study has the purpose to the improvement of health promotion for local residents through delivery of high-quality medical service by improving imbalance of medical use and seeking an improvement plan for accessibility of effective medical service by understanding the pattern of medical use by region. Methodology: As for the method, this study derived results at the significance level of p<0.05 through chi square test(χ² test) and Generalized Estimating Equation(GEE) SAS 9.4 version by using the data of the 7th Korean Longitudinal Study of Ageing 2018. Findings: Study results show that local residents use medical service such as hospitalization care and outpatient visit more as compared to the residents in Gyeonggi-do/large or medium-sized cities. The more the number of chronic disease, the more they select hospitalization care rather than outpatient visit. Results also show that patients engaged in labour tend to select outpatient treatment rather than hospitalization treatment. Meanwhile, severity of disease turned out to be higher amongst medical care beneficiaries than that of national health insurance patients when comparing the types of medical security. Practical Implications: In stead of solving the problem of the difference in medical use by region from the aspect of income and economic level, an integrative solution shall be provided putting viewpoint on the social phenomenon suited to the changes of the times. This study suggests a plan for using a health and medical community care center that acts as a gate keeper of regional medical service.

The new millennium has started with several innovations driven by fast evolution of the technologies in energy sector. A strong impulse towards the diffusion of new economical efficient technologies regulatory incentives related to energy production from renewable source and a small scale building trigeneration and to promotion of more sustainable environmental-friendly generation solutions, the evolution of electricity markets, more and more binding local emission constraints, and the need for improving the security of supply to reduce the energy system vulnerability. The 24 percentage energy quantify of total energy consumption consumes in commercial buildings and residential houses and the 30% portion of total $CO_2$ emissions covers also in the commercial buildings and residential houses sector. To cope with efficiently this energy sinuation in building sector, Building microgrid or building tooling, heating & power(BCHP) system has been interested in recent day due to meeting thermal and electric energy requirements efficiently and with appropriate energy quality. A multi agent system is a collective of intelligent agents that communicate with each other and work cooperatively to achieve common goals. Also, it is to medicate and coordinate communication between Control Areas and Security Coordinators for teal-time control of the BCHP system and the power pid. In this new circumstance, it is very important to integrate the power and energy delivery system and the information system(communication, networks, and intelligent equipment) that controls it. Therefore, development of smart control modules with open communication protocol and seamlessly interchange the data and information between control network and data network including extranet and intranet give a great meanings. We designed and developed the TCP/IP-CAN IED agent modules and ModBus./LonTalk/(TCP/IP) IED agent ones to configure the multi-agent system based smart energy network of commercial buildings and also intelligent algorithms for inverter fault diagnostics which ran be operated in control level or agent level network.

본 논문에서는 공유 네트워크에서 최소 공유대역폭 트리 구축 문제의 근사해를 구하기 위한 선형 시간 알고리즘을 제안한다. 공유 네트워크는 자신이 소유한 AP의 일부 대역폭을 다른 사람들과 공유하는 사용자가 생성하는 통신 기반 구조로 사용자는 이러한 공유 AP를 통해 어디서나 인터넷을 사용하고 데이터를 전송할 수 있다. 최근에 공유 네트워크에서 SVC 기술을 사용하는 비디오 스트리밍 전송 시스템을 구축하는 방안이 제안되었는데 서버로부터 모든 클라이언트에게 비디오 스트림을 보내기 위해서는 트리 구조를 만든다. 클라이언트의 비디오 스트림 요구를 전부 만족시키는 트리 구조를 생성하는데 있어, 사용되는 공유 AP의 공유대역폭의 합이 최소가 되는 것이 바람직 한데 최소 공유대역폭 트리 구축 문제는 NP-하드임이 증명되어 있다. 이 문제를 해결하기 위해 기존에 발표된 알고리즘들은 해를 잘 찾지 못하거나 효율적이지 못한 단점을 가지고 있다. 실험 결과를 보면 제안 알고리즘이 기존의 알고리즘보다 해를 찾는 성공률이나 해의 결과에서 모두 우수하였다.

Obstetrics and Gynecology include gynecology which is concerned with the treatment for the disease based on physiology and pathology of women, and obstetrics which is concerned with pregnancy delivery. These obstetics and gynecology can be said to date from the birth of human beings. This paper has carried on the studies about the generating and developing process of obstetics and gynecology. The results of this study are as follows : Distinction in Northern and Southern Dynasties were much more Obstetrics and Gynecology studying the Obstetrics and Gynecology books in that time, the study about "oncosis" (腫瘤) and forms of drug, pill, powder, pIaster were carried on. The highest distinction in Sui age were research and development on pathogenesis and cause of disease about Obstetrics and Gynecology disease and it was appeared representatively in "Zhubingyuanhoulun""諸病源候論" which was special book on cause of disease and pathogenesis and syndrome, And it was explained about abnormal vaginal discharge in this book. Obstetrics and Bynecology were developed on theory and clincis in Tang age when "Taiyshu"(太醫暑) was established. "Taiyshu"(太醫暑) taked complete charge of medical operation and education, published much excellent Obstetrics and Gynecology books than the past. Among them specially "Qianjinyaofang""千金要方" explained Obstetrics and Gynecology matter first in three volumes and "Qianjinyifang""千金翼方" explained this matter first in four volumes. This point indicate that Obstetrics and Gynecology's importance was established in Tang age, so Obstetrics and Gynecology's developmental history, Song age was the acme period. "Taiyju"(太醫局) was established in "xining""熙?" 9 year and Obstetrics belonged to one of nine departments under "Taiyun"(太醫局), so Obstetrics and Gynecology was separated from the other medical parts and it was prepared of it's progressing bases independently and appeared of changes in quality and increase in quantity about theory and prescription of Obstetrics and Gynecology, specially determination of treatment based on the differentiation of symptoms and sighs was taked a serious view. Besides four great physicians in Jing and Yuan dynasies diversified Obstetrics and Gynecology contents through their only medical theory and clinical treatment.

Purpose: To analyze health programs of the PHCP (Primary Health Care Posts) Method: From August 2006 to July 2007, data on the general quality and health program of the PHCP was requested by official letter and replies were received via E-mail. From December 8 to December 30, 2007, data from 1,268 (66.8%) PHCP out of 1,897 PHCP were analyzed using SPSS 12.0 Win program. Results: The average population covered by each PHCP is 878.3 people. For the health and special programs, Community Health Practitioners report high motivation for programs on health promotion, management of chronic illness, social welfare (40-50%). Demand by the residents was reported at 10% and increases in the health of the residents were attributed to high interest and demand. Volunteer work was 83.3% for bathing, 54.5% for equipment support and 46% for exercise programs. As elders make up 30% of the population in rural areas, there is an increasing demand for volunteer work in bathing programs. Conclusions: As the number of elders in the population increases and there is an increased need for more medical treatment for older people who are sick, the role of PHCP must be strengthened to include visits to homes of community residents. Where financial support for the PHCP is difficult, it is necessary to develop sound data on demographic characteristics of the population in order to develop efficient and effective health promotion programs. The finding that 54.7% of the population need management of chronic illness has difficulty in seeing a physician indicates a need to enhance the health care delivery system by strengthening the role of the Community Health Practitioners and including them in the civil service system to ensure stability of the PHCP.

Since Chrysler Motor Co. had experienced the digital development system in the beginning of 1990's, most of leading automobile companies are trying to apply a digital information system for their own business process reengineering based upon concurrent engineering system from product planning phase. This is called as virtual DMU(Digital Mock-Up) system instead of the traditional PMU(Physical Mock-Up) system. By using the virtual prototype, all of the design requirements and system specifications can be checked, changed and optimized more quickly and more efficiently. This paper consists of five chapters for the DMU information system. In the 1$^{st}$ chapter, the principle of digital design system is suggested by using four basic modules such as product design module, process design module, manufacturing system design module and central control module. The basic scheme of DMU is introduced with the benefits of application in the chapter 2. In the chapter 3, a digital design process of new car development is explained with the detailed DMU design and design review processes. In the chapter 4, the practical DMU manufacturing techniques and applications are introduced as CAD/CAM analyses, DPA(Digital Pre-Assembly)reviews for development, production, operation and maintenance phases, digital tolerance analyses and digital factory analyses for assembling line simulation, automated robot welding processes, production jig ＆ fixtures and painting process simulation. Finally, the activities of digital design support; CAS-styling, CAE-engineering and CAT-testing are summarized for design optimization in the chapter 5. As today's automobile manufactures and related business organizations are struggling to compete in the global marketplace, they are concentrating on efficient use of DMU information system to reduce the new car development cost, to have shorten the delivery schedule and to improve product design quality. To meet the demand of those automobile industries on digital information systems, the CALS(Computer aided Acquisition and Logistics Support) and EC(Electronic Commerce)initiative has been focused as a dominant philosophy in defense ＆ commercial industries, specially automobile industries.s.
