In keeping with the increasing demand for medical services in accordance with the economic development, the use of oriental medicine is on the rise year by year. In particular, it is a tendency that the elderly over age 65 prefer the oriental medicine to the western medicine in Korea. Under the circumstance, changing into an aging society, the importance of oriental medical services has been growing. In this regard, this study evaluated the quality of medical services by conducting the density analysis and the accessibility analysis of oriental medical clinic targeting Jinju, which is one of local small and medium-sized cities. The study results reveal that oriental medical hospitals accounted for 27% of the entire medical facilities in Jinju, and there was an imbalance in the quality of the oriental medical services according to districts(called dong) because oriental medical hospitals were mainly concentrated in the central commercial areas. In particular, in terms of the analysis on the accessibility of an aging population over age 65 to the oriental medical hospitals, over 50% of the whole districts (dongs) in Jinju were blind spots in medical services, showing a very vulnerable condition. Accordingly, it is judged that systematic measures for improvement in support of the oriental medical services in local small and medium-sized cities should be provided in Korea when we consider the characteristics of Korea where an aging population is rapidly increasing.

The increased interest in consumer health information(CHI) has brought about a rapid increase in CHI resources. There are diverse means for obtaining such information, and one CHI acquisition route is the public library. In the U.S. public libraries, the demand for CHI reference services is increasing, and a variety of projects to promote these services are in progress. On the other hand, Korean public library services for CHI is at a very basic level, and thus a very small amount of such research could be found. This study drew suggestions from a literature review of research studies in the U.S. and Canada, and analyzed public library CHI services in Korea. The findings are as follows. 1) Only 17.25% of public libraries in Korea provided CHI service, and it evidences very low needs and awareness for CHI services in Korea. 2) Only three kinds of services including CHI-related websites, users training, and promotional and marketing were provided, and only 13(1.74%) of libraries surveyed offered more than two kinds of services. 3) There were no CHI librarians, nor did any librarians receive CHI-related education. 4) ILL services, outreach services, and cooperation with CHI- and medical-related institutions for CHI services were not found. Therefore, this study suggests that more research on delivery strategies for CHI services should be conducted in the future.

Recently, more focus is shift to imbalances in aggregate market supply and demand and an exhaustion of natural resources. In this situation, Electric arc furnace oxidizing slag (EAF Slag) has high application possibility as aggregate for concrete due to similar property with general aggregate. In this study, We've got the plan to assure the chemical stability of EAF Slag, and then experimentally tested the mechanical performance and durability for the fine aggregate used EAF Slag. On this test result, we suggest the application plan. At the result of this study, it shows that EAF slag would reduce the surface defect such as pop-out due to natural aging for the fixed hour and adjustment the grain size of EAF Slag. And mechanical performance and durability according to the replacement rate of concrete service, were revealed more than equal or equal compare to general aggregate. Hereafter, quality control must precede not to impede the beauty of concrete surface as assure the safety for aging and processing. And, to establish the environmental resource recycling system for by-products of steel, it should be made development of various application and guideline of quality control for the EAF slag aggregate. Moreover, it must be constantly studied all kind of engineering performance and durability for related to this study.

Modern society often faces 3Cs：change, competition, and customer. The main issue of today's police science study, therefore, circles around how public police effectively cope with the radically changed environment. As one of the workable and appealing policy tools to reform the police, the privatization has been not only strongly supported in terms of a theoretical study, but also widely used in practice all over the world. However, Policing has been widely regarded as an exclusively public-sector activity conducted by sworn officer, but a large and increasing share of the aggregate demand for public safety and security is being handled by the private sector. This study examines on the very practical one, how contracting out, most widely used as the privatization alternatives, is perceived and put into practiced in the field of traffic police services. This study is intended to examine recent shifts toward privatization of traffic policing. Although some people regard police services as inappropriate for privatization, most everyone else have persuasively considered that many police services are not public goods or, at least, not pure public goods. We can consider that there are three types of privatization with respect to traffic policing, that is, user-financed police services, contracting out, and some degree of service shedding. As society changes, so must traffic policing. And it is needed to enhance the ability of traffic police and private to accomplish their primary mission, to serve and protect the public.

The Area of a domestic railway station is designed based on the 4-step traffic demand forecasting model with the average daily passenger count as one of its parameter. However, nowadays, due to increasing rate of railway station's function, the non-passengers are increasing. In order to consider those non-passengers who aren't using trains, assumed volume are added to the average daily passenger count of station to estimate the area, but the criteria being applied has no concrete basis. Therefore, this study aimed to recalculate the increasing non-passenger rate based on actual survey data of station users in any type of railway station to obtain the optimum area. Subsequently, the the design area was performed through pedestrian simulation. According to the result of the simulation, it was found that the total space of the exciting railway stations can be reduced up to 45% and will still satisfy the level of service(LOS) requirement.

Subway station scales are determined by peak predictions. In this study, the purpose behind the installation of a subway is public transportation convenience and public interest, but economic validity is also important. By proving that the scale of the station is excessive with regard to the target station size for Seoul subway Line 5-8, a reasonable plan. can be sought. According to station installation standards, the area of the station under investigation here is out of the service levels by six stages (A~F), and it must be four or more levels (D). The Actual level for the B level is a two-step design. The Actual ratio for over- Peak predictions is only 17.8% on average. The results of measurements of the excess area and determination of the excessive costs were analyzed by subdividing the area and by calculating it based on the B level, finding that it is possible to provide benefits for customers only in the current design, with an area ratio of 16.3%. Given the weight, it was estimated that current conditions can meet the needs of only 18.6% of the current area. Simplifying the scale calculation method of the station, it is convenient, safe, and advantageous to move citizens only if the scale can be streamlined. Then, with a reduced initial investment, maintenance costs during the operation can be reduced.

In this, analyzing the type of subjectivity in which people would have about home visit nursing services originating from public health care centers. I tried to research more effective ways to improve home visit nursing care services. and later. for the development of home visit nursing care. to supply basic data. The method for this study was the Q-method. created by William Stephenson. and was adequate for the study of subjectivity. For this study. through the deep interview. literature inquiry, and the discussion course. 206 Q-statement sentences were abstracted. and based on them, after Q-sample-selection. I then collected the Q-categorized-result from 32 subjects from Mar. 10. 2000 to Mar. 25. 2000. Through the statistic a analysis of PC-Qunal program. the subjectivity species were categorized and analyzed. The study results show that there are 3 sorts of recognition types. and they are analyzed in the following; The first type: the positively receiving type shows that they feel thankful and a trusting feeling about home visit nursing. The second type: the negatively mistrusting type shows that they had doubtful attitudes about the specialty of home visit nursing: they wanted medicine or nutrition remedies rather than health education and concerning the their own health care, they prefered the hospitals or clinics. The third type: the conditional receiving type shows that even though they had a positive receiving attitude about home visit nursing wanting to consult with the home visit nurses about the difficult problem which could not easily be settled, hoping that the home visit nurses could visit them more often, in their actual lives. they strongly indicated their attitudes concerning money as more important than home visits. The subjects in these 3 types commonly had a good feeling about the kindness of the home visit nurses: the first and third types also had a positive recognition about home visit nursing; however. in aspects of the evaluation and receiving attitudes, they showed a big difference. When all the above results are integrated. in the case of the first type the home visit nursing service, which satisfied the demand for health care of the medically weak people. should be continuously supplied. Additionally in case of the second type (negatively mistrust). continuous education and support should be supplied with enough interest to lead their concerns about their own health care as well as lead medical spending in a productive and effective direction in order to change their impressions. Through this study. I learned that the recognition of the objectives of home visit nursing services can be categorized in to 3 types and could be analyzed. Thus I wish that this study helps to present basic data which contributes to the development of the home visit nursing field.

WLAN(Wireless Local Area Network) standard is currently developing with increased wireless internet demand. Though existing IEEE 802.11e demonstrates that data rates exceed 54Mbps with assuring QoS(Quality of Service), wireless internet users can't be satisfied with real communication system. After IEEE 802.11e system, Study trends of IEEE 802.11n show two aspects, enhanced system throughput using aggregation among packets in MAC (Medium Access Control) layer, and better data rates adapting MIMO(Multiple-Input Multiple-Output) in PHY(Physical) layer. But, no one demonstrates IEEE 802.11n system performance results considering MAC and PHY connection. Therefore, this paper adapts MIMO in PHY layer for IEEE 802.11n system based on A-MPDU(Aggregation-MAC Protocol Data Unit) method in MAC layer considering MAC and PHY connection. SVD(Singular Value Decomposition) method with WLAN MIMO TGn Channel is used to analyze MIMO. Consequently, Simulation results show enhanced throughput and data rates compared to existing system. Also, We use Ns-2(Network Simulator-2) considering MAC and PHY connection for reality.
