Objectives : The purpose of this study was to evaluate effects of alcohol on psychomotor performance and subjective assessments in normal adults with high and low trait anxiety. Methods : The subjects consisted of 11 men in each group were tested with two doses of alcohol(0.25g/㎏ and 0.75g/㎏). Blood alcohol concentration(BAC), psychomotor performance(critical flicker fusion threshold, CFFT ; choice reaction time, CRT) and subjective assessment were measured at pre-alcohol baseline and 20, 40, 80, and 160 minutes after intake of alcohol. Results : 1) There was no significant difference in BACs between two groups at any time points after intake of each dose of alcohol. 2) After intake of 0.25g/kg alcohol, high anxiety group, compared to low anxiety group, reported less anxious and more relaxed feelings. In psychomotor performance test, however, there was no significant difference between the two groups. 3) After intake of 0.75g/kg alcohol, CFFT was increased in high anxiety group while it was decreased in low anxiety group. In subjective assessment, only high anxiety group tended to show more positive response. Conclusion : These results imply that alcohol may be more beneficial in individuals with high trait anxiety than those with low trait anxiety in terms of objective performance and subjective feelings. Furthermore, these suggest that the alcohol benefits might contribute to drinking more alcohol and frequently in individuals with high trait-anxiety.

This paper reports on a priority decision making model analysis in order for program directors who are in charge of Corporate Social Contribution to make the optimal decision. This empirical analysis focuses on discovering the most significant area among current various programs of Corporate Social Contribution Activities. The Analytical Hierarchy Process (AHP) is employed to test the priority preference. More specifically, it attempts to demonstrate how the priority decision making model helps providing better choices in Corporate Social Contribution Activities practices. The priority preferences of Corporate Social Contribution Activities programs among corporate social contribution practitioners, PR professors and NGO activists are examined. In conclusion, the priority decision making model for Corporate Social Contribution Activities programs should be integrated as the key part of corporate strategic plan. Moreover, it should be considered as a part of overall social welfare including environmental preservation.

The present study reports a case of inverted papilloma of the nasal cavity and infiltrating into the maxillary sinus. Inverted papilloma is an uncommon and locally aggressive benign tumor of the sinonasal region. The patient, 51-year-old male, presented with unilateral nasal obstruction and periodic swelling on the palate without pain. Enhanced CT scan revealed a heterogeneously enhancing solid mass in the nasal cavity and infiltrating into the right maxillary sinus, as well as an incidental, secondarily infected residual cyst m the periapical area of the right maxillary canine. The sinonasal mass was revealed as an inverted papilloma on histopathologic examination.

차량, 항공기, 그리고 각종 기계 구조물에 대한 진동 평가나 설계 또는 훈련을 위한 실제 실험은 비용이나 실험 환경 등에 있어 많은 제한을 받게 된다. 그러므로 실제 운동조건과 같은 환경을 제공하는 가진 시뮬레이터는 설계나 평가에 있어 대단히 편리하면서도 경제적인 이점을 제공하여 준다. 본 논문에서는 휠(wheel)에 작용하는 3가지 요소, 연직 하중(vertical force), 전후 하중(longitudinal force), 횡 하중(lateral force)을 복합적으로 재현할 수 있는 링크 구조인 다축 시뮬레이터(multi-axis simulator)를 설계하여 기구학적 해석을 하였고, 동역학 해석 프로그램인 ADAMS TM로 시뮬레이션을 하여 다축 시뮬레이터에 요구되는 조건과 비교하였다. In the experiments of vibration evaluation, and test of vehicles, aircraft, and other mechanisms the development of vibration simulator that serves environment similar to real fields takes lots of advantages. In this research, link-structured multi-axis simulator is designed. It can simulate wheel-applied force which is compounded force; vertical force, longitudinal force, lateral force. Kinematic analysis on this system is performed and simulated on computer as well using ADAMS and then two results of them are compared and analyzed.

Recently, Korea has been experiencing a major bad-debt problem in the financial industry that has almost crippled the entire Korean financial system and the economy. It is widely viewed that the severe nature of problem makes it impossible to resolve without a major restructuring in the financial institutions. Thus, Merger & Acquisition among financial institutions are one of the most important features in the Government-led plan to restructure and rebuild healthy competitive financial industry. To provide a more merger-friendly environment and thus expedite the restructuring process, it is imperative to identify those features in the current institution that make M&A difficult and eliminate them. The purpose of this study is to suggest the direction for improving monetary circulation system of Korean industry by understanding the strong point of advanced country industry.

강용태,김화석 東亞大學校 建設技術硏究所 2001 硏究論文集 Vol.25 No.2

Most of existing combined septic tanks of household wastewater and night soil have been treating medium or small scale domestic wastewater by means of activated sludge process. But this process is mainly organics-removed process such as BOD and SS. So nitrogen and phosphorus which is the main issues of eutrophication are not properly treated in this process. Therefore, in order to treat nitrogen and phosphorus stably, in this study, retrofical combined septic tank including sludge stabilization basin is applied to a small domestic wastewater treatment facility and treatment efficiencies of organic matter and nutrients and economics in this process are investigated. As a initial operation results of Activated Sludge(AS) process and Advanced Step Aeration(ASA) process applied as combined septic tank, SS and COD removals in ASA process compared to AS reached the steady state in a short term. T-N and T-P removals in ASA process is from fifteen to twenty percent higher than those of AS process. Results investigating the economics of ASA process have it that in case of comercializing ASA process as a small treatment plant(such as FRP tank) it is described that ASA process is to be saved to the degree of from ten to fifty percent in compared with other methods.
