Previous studies indicated that unmarried persons are subject to higher mortality than the married, and that the differentials are more marked for male than for females. There are two major approaches to explaining the marital status differentials in mortality ; selection function and protection function of marriage. Following protection fucntion, this study develops the new "instrumental / expressive sex-role" hypothesis in order to explain why marriage protects males more against death. The hypothesis expects that male's instrumental role and female's expressive role have direct effect as well as indirect effect through social integration on sex differential mortality by marital status. for the hypothesis testing, Korea and US vital statistics and census data are used to compute age-specific , age-adjusted mortality rates and their ratios for persons in different marital status. Major findings are as follows. 1)For both Korea and US being married is more advantageous to males than females, ad being widowed, divorced, and separated is more disadvantageous to males, while being never-married is more disadvantageous to females, 2) For Korea, the never married men and women have the highest mortality rates, 3) For US the never married women have the highest mortality rate, while the divorced, separated, and widowed men have the highest mortality rate. Fro both Korea and US data, selection function is rejected, but instrumental/expressive sex-role hypothesis succeeds in accounting for the sex and marital status differential in mortality.

If the implant is planted in the wrong position or direction, it is disadvantageous for stress distribution, and it is easy to cause complications such as screw loosening, abutment fracture, and implant fracture. If the position or orientation of the implant is not good, efforts should be made to minimize the problem through proper implant prosthetic treatment. In this article, the prosthetic method for facilitating future maintenance in cases with poor implant placement or orientation will be presented.

Subsequently in Korea product liability has been introduced. The position of consumers for defective products have been disadvantageous. Defective products should be broght under the law. Then, while consumers would be largely protected, a producer would take the heavy responsibility by law, Therefore, a producer would not be able to take countermeasures for product liability. Object of this paper to investigate and analyze the actual state of management for product liability in advanced countries, and to join it with our quality management system.

As microprocessor and SOC (System On a Chip) performance moves into the GHz speed, the high-speed asynchronous design is becoming challenge due to the disadvantageous power and speed aspects in synchronous designs. The next generation on-chip systems will consist of multiple independently synchronous modules and asynchronous modules for higher performance, so the interface module for data transfer between multiple clocked IPs is designed with Xilinx FPGA and simulated with RISC microprocessor.

Objective : The purpose of the study was to investigate and compare the differences between Parkinson's disease rating, balance, fall and gait scales. Results : Parkinson's disease rating scales include the Hoehn-Yahr Scale and the Unified Parkinson's Disease Rating Scale (UPDRS). The Hoehn-Yahr Scale can measure disease rates easily; however it is not sensitive enough to evaluate the disease's process and management. UPDRS's advantage is in it's higher inter-reliability score; however it is more complicated to use. Parkinson's balance scales are comprised of the Berg Balance Scale (BBS) and the Activities-Specific Balance Confidence Scale (ABC). BBS has the advantage in that it is cheaper to measure and simple in use. ABC's advantage is especially in it's ability to measure higher functional levels; however it is more difficult measure responses due to scores appearing in both extremes. The Fall Efficacy Scale (FES) and The Survey of Activities and Fear of Falling in the Elderly (SAFE) are Parkinson's fall scales. FES's leverage over SAFE is that it is simpler to measure; however it does not coincide with responses which proves disadvantageous in measuring balance loss in high-level Parkinson's patients. SAFE's advantage is in it's simpler use and ability to be utilized without encountering the fear of fall; however it's at a disadvantage in regards to its use with multilateral aspects providing insufficient inspection. Lastly, the Dynamic Gait Index (DGI) and the Functional Gait Assessment (FGA) are Parkinson's gait scales. DGI is advantageous in its ability to test gait ability when exposed to a variety of external environments; however it is disadvantageous in that it registers higher scores with activities. FGA's advantage is in it's dynamic balance test; however it at a disadvantage with those unable to walk. Conclusion : A researcher of Parkinson's patients must choose each scale while considering their positive and negative characteristics.

본 연구는 청소년에 대한 빈곤의 영향을 주로 가족의 측면에서 연구하였던 기존의 관점에서 탈피하여, 빈곤청소년이 거주하는 지역사회 환경의 위험성과 폭력성에 주목하였다. 즉, 본 연구는 빈곤으로 인해 더 위험한 환경에서 거주하게 되는 청소년이 일반 청소년보다 폭력에 더 많이 노출되는지를 살펴보고, 이것이 그들의 우울과 불안을 높이는지 분석하였다. 분석 자료로 '한국청소년패널데이터' 중2 패널자료 중에서 3-5차년도 종단데이터가 활용되었으며, 통계방법으로는 구조방정식모형이 이용되었다. 분석 결과, 청소년의 빈곤 자체가 폭력피해 경험을 직접적으로 증가시키지는 않았으나 빈곤으로 인해 위험한 지역사회 환경에 거주하게 됨으로써 더욱 많은 폭력피해와 두려움을 경험하게 되며 이는 우울 및 불안으로 이어지는 것으로 나타났다. 이 결과를 바탕으로 청소년에 대한 빈곤의 부정적 영향을 줄이는 데에 지역사회의 역량 강화의 중요성을 함의로 지적하였다.

Through the examination of literatures, electronic commerce is a subject which is accepted in enterprises to define e-commerce adoption, trends, and issues that are assisting and obstructing its efficacy. E-commerce offers numerous advantages to consumer satisfaction in any place and helps the company to get a competitive benefit over its competitors. The Internet has expanded the scope of business. Many business information is available by the global network that supports information gathering between organizations, businesses and their clients, while various divisions of a business is increasing at an exponential rate. Meanwhile, there are a few barriers to proper e-commerce usage and adoption, such as reliable internet connections, poor e-commerce supporting infrastructures, logistics systems presenting socio-regulatory and poor transportation barriers and demonstrating the significant improvement of e-commerce reliable and affordable Internet provisions, i.e., Internet cost, intensity, and reasonable level of e-readiness. The operational and strategic significance of information-based virtual value chains for all organizations cannot be emphasized. As a consequence, this study confirms worldwide market elements of e-commerce, such as its issues, benefits, relevance, scope, facilitators and projects prospective obstacles in a developing economy.

Recently many disadvantageous problems have been found during the process of domestic LRT(Light Rail Transit) projects and that can influence negative effects on the development of domestic railway. Since many projects have been progressed while having few original technologies, it is no exaggeration to say that they are being built unreasonable railway which lacks economic feasibility. The on-going LRT projects which are being carried out by the central or local government have a tendency to favor the systems and rolling stocks that have been approved by other countries through years of experience, therefore it can be said that we are having few chances to develop original technologies. In this study, we would like to promote railway development and jump up to the level of advanced railway standards through developing our unique and independent future LRT technology.

In this study the economic impacts of government support of shipping industry in the labor rich country are appraised in a general equilibrium model. Shipping industry subsidies (which are supposed to be supplied by lump-sum tax) will decrease disposable income by shifting productive resources from traded goods to the comparatively disadvantageous transport sector, and at the same time reduce the implicit tariff effect by lowering transport costs. The net effect of shipping industry subsidies is to increase social welfare because the latter positive effect of shipping industry subsidies is to increase social welfare because the latter positive effect dominates the former negative effect. Such an increase in social welfare can never be expected from competitive traded goods industry subsidies in the case of which social welfare will actually decrease because of inefficient resource allocation resulting from the subsidies. In addition it is worth noting that the subsidies on the most capital intensive shipping industry will rectify unevenness in income distribution by raising relative price of labor contrary to subsidies on capital intensive traded goods.
