The overall area of Taiwan is 36,006 km$^2$ and population was about 22,535,000 persons in 2003. The population density became 625persons/km$^2$. The economic of Taiwan progress since 1970. Gross national production in 2004 increased by 2.3 trillion or 493% relative to 1981. The number of automobiles in 1981 was 821,862, and increase to 6,389,186 in 2004. The number of motorcycles in 1981 were 4,591,547 and increase to 12,793,950 in 2004. The vehicle growth rate of automobile and motorcycle was 677% and 178% respectively. The recycling end-of-life vehicles(ELVs) is specified in the Waste Disposal Act. Its main content is the system of asking the vehicle manufacturer and importing agents, who are responsible for recycling of the ELVs. The recycling task on ELVs was startedinitially in 1993. It is required that the manufacturers and importing agents deposit certain ratios of Waste Vehicle Disposal Fees proportional to the number of vehicle they manufacture and import into Taiwan under sales. This report will introduce the current status of ELVs recycling in Taiwan, and the future direction, as well as measures proceeding for the EPA- Fund Management Committee(RMFC) operating in the fiture.

연세대학교 영동세브란스 병원에서 94년 요통환자 2천4백10명을 직업별로 분류한 결과, 주부가 56%, 학생이 13.4%를 차지했다고 발표했다. 특히 주부환자비율은 85-90년에 38.9%로 조사된 것에 비하면 주목할만한 증가세를 보였다. 이러한 주부요통증가의 원인 중 임상적으로 이미 확인된 것이 하이힐에 의한 것이다. 하이힐을 신을 경우 허리에 부담을 주고 요통을 유발할 수 있다는 것이다. 그러나, 이러한 임상적 가설에 대한 구체적인 연구나 검증이 이루어진 바 없어 하이힐이 허리에 어떤 영향을 주는지에 대해 확인할 수 없었다. 따라서, 본 연구에서는 하이힐이 허리에 미치는 영향에 대한 임상적 가설을 검증하고 영향 정도에 대한 구체적 수치를 제시하고자 한다. 이를 위해 5명의 신체 건강한 20대 초반의 여성들이 모집되었고, 하이힐의 굽높이를 독립변수로, 허리 근육 피로도를 종속 변수로 설정하여 하이힐의 굽높이가 허리 근육에 미치는 영향에 대해 조사하였다. 허리 근육 피로도는 Spectral EMG를 통해 분석하였고 정량화되었다. 측정된 자료를 통계 분석한 결과, 하이힐의 굽높이가 여성의 허리 근육에 유의하게 영향을 미침이 발견되었고, 우리 나라 여성에게 적합한 하이힐의 굽높이는 3-5cm 정도임이 밝혀졌다. 본 연구 결과는 하이힐의 디자인에 있어서 굽높이에 대한 추천치로 제안될 수 있으며 여성들의 하이힐로 인한 요통을 어느 정도 예방할 수 있어 여성 근로 손실을 줄이는 데 기여할 수 있다. 본 연구를 하이힐 굽형태나 충격흡수 등의 독립변수 요인을 추가하여 확대하면 하이힐 디자인에 응용하는데 더욱 유용하리라 생각된다. 없었다. 전신쾌적감은 약간 쾌적하게 나타났고 전신온냉감은 약간 따뜻하다라고 나타났으며 손가락끝의 동통감은 약간 아프다고쪽으로 나타났다.때문에 이를 디자인에 곧바로 적용시키기 어려운 점이 있다. 이에 본 연구는 기존의 바용성 평가를 위한 분석도구들이 갖는 문제 점들 해결하여 제품의 사용자 인터페이스 디자인 개발과정에서 활용할 수 있는 평가 분석도구를 개발하는 것을 목표로 한다. 이를 위해 첫째, 다양한 유형의 정보를 포함하는 비디오 정보를 선정하였따. 둘째, 데이터를 다양한 측면에서 추출할 수 있는 Data logger를 개발하였다. 셋째, 데이터를 시각적으로 정리하고 분석할 수 있는 도구를 제안한다. 마지막으로 인터페이스 디자인에서 여러 가지 디자인안을 도출해 내는 작업에 이용할 수 있는 종합화과정을 개발한다. 이러한 일련의 과정이 통합된 컴퓨터 시스템 안에서 이루어지도록 프로그램을 개발하여 정보의 유용성을 높일 수 있도록 한다.at the entropy index as a measurement of inter-business relatedness is not significant but technological relatedness index is significant.

In the planning phase of domestic urban environment maintenance and improvement projects, a particular problem is the increase in service expenses and project cost with the establishment of plans under circumstances that exclude the residents or have incomplete consent from them and the public organization. This delays the promotion of the project. This study aims to resolve such problems by proposing a measure to introduce a privatepublic consultative body for residents and the relevant departments of the public sector, to encourage them to participate and establish plans together from the beginning. This is expected to contribute to the smooth promotion of the project, as it would remove the conflicting factors that are expected to be generated in the project implementation phase before they could emerge.

The Korean government is planning to introduce the Renewable Portfolio Standard (RPS) system to replace the currently used Feed-in-Tariff (FIT) system which is a subsidy-based mechanism to foster the renewable energy industry. The RPS system is a market-oriented system in which the power companies are obliged to use renewable energy sources to produce electricity by a certain ratio of their production level. They can either produce for themselves or simply purchase the REC (renewable energy certificate) in the market to implement. The objective of this article is to compare the RPS system with the current FIT system in terms of the implementing cost to achieve the policy goal to expand the share of renewable energy m the total power generation. The analysis is conducted using Linear Programming models. The results of this study imply several policy suggestions to successfully introduce the RPS system.

To provide some suggestions on the setting of mathematics test in the College Scholastic Ability Test(CSAT), this paper analyses the result of mathematics test in the CSAT from 2005 to 2011, on which the 7th national mathematics curriculum has been applied. From the result, four suggestions are drawn out. First, the mathematics test needs to be easier to reduce the burden of test-taker. Accordingly, the number of items and their scores need to be adjusted. Second, the proportion of multiple-choice items has to be reduced whereas that of short-answer items has to be increased to enhance the function of the CSAT as a selection test. Third, the sub-item system needs to be adopted. Fourth, new item-types have to be developed.

The one of the core technologies for ubiquitous computing is WSN. WSN detects the information from the environment around them based on the information perceived from the human and all things and manages the information by connecting to the network in realtime. In this environment, the existing research provides the mechanism that most of sensor nodes in the target area can set the transmission path using RGF. However, unrelated to the target area will be responsible for the energy consumption of nodes that are the problem. In this paper, we propose EEDCP protocol. It is designed to collect data from the specific region on sinks in WSN. EEDCP is the protocol that sets the transmission path for collection data inside the target area in WSN. And this paper is shown that the proposed scheme is more efficient in the energy efficiency and the occurrence rate of isolated nodes by comparison with the previous studies through simulation.

Smart TV System will lead to drastic change of communication and media industries as one of the emerging next generation network services. However, when the number of concurrent users increases rapidly, the issue of service quality degradation occurs because providing services to many users simultaneously stresses both the server and the network. The server limitation can be circumvented by deploying server clusters. but the network limitation is far less easy to cope with, due to the difficulty in determining the cause and location of congestion and in provisioning extra resources. In order to alleviate these problems, a number of schemes have been developed. Prior works mostly focus on reducing user-centric performance metrics of individual connection, such as the round-trip time(RTT), downloading time or packet loss rate, but tend to ignore the network loads caused by the concurrent connections or global network load balance. In this work, we make an in-depth investigation on the issue of user grouping for massive Smart TV services through simulations on actual Internet test-bed, PlanetLab.

This study aimed to analyze effects of non-regular employment rate and female employment rate on fertility rate in OECD county. We adopted dynamic panel model after classifying OECD county to high and low fertility rate. The results of analysis showed that the higher non regular employment rate, the lower female employment rate, and the lower economy growth rate decrease fertility rate especially in low fertility rate country. While, only the higher house rental decrease in high fertility country. This results indicate that low fertility country including Korea should improve a labor policy such as strengthening employment security and encouraging female employment to increase fertility rate.

Since 2005, the government began to introduce and promote a new project delivery system, BTL(Build, Transfer, and Lease), in order to provide high level of public services for the upgraded quality of life and to boost the domestic and local construction economy. However, the lack of experiences in the new system by the constituents from diverse economic sectors brought a number of drawbacks from each constituent's perspective such as improperly low earning rate, excessive expenses for preparation of the project proposal, imbalanced regulations, heavy cost and procedures to establish SPC, the ineffective structure of the consortium, the short-term oriented evaluation criteria for the selection and so forth. These drawbacks turned out to be obstacles for the successful BTL projects. Hence, this paper analyzes the above issues and conducts the interviews with the professionals from the diverse sectors in order to propose the changes to resolve those for the improvement and finally to deliver the successful BTL projects for the diverse public owners.
