Chemical vapor deposition (CVD), ion beam sputtering (IBS) and sol-gel method were used to prepare TiO$_2$ thin films for degradation of hazardous organic compounds exemplified by 2-chlorophenol (2-CP). The influence of supporting materials and coating methods on the photocatalytic activity of the TiO$_2$ thin films were also studied. TiO$_2$ thin films were coated onto various supporting materials including steel cloth (SS), copper cloth, quartz glass tube (QGT), and silica gel (SG). Results indicate that SS (37 μm)- TiO$_2$ thin film prepared by IBS method improves the photodegradation of 2-CP. Among all supporting materials studied, SS(37 μm) is found to be the best support.

본 연구는 여대생의 노인부양의식, 노인에 대한 지식 및 태도, 부양의식관련 특성을 파악하고 이들 간의 관계를 확인하는데 목적을 두고 있다. 연구는 서울소재 한 여자대학교 교양수업시간에 노인부양의식과 노인에 대한 지식 및 태도에 대한 설문지를 이용하여 실시하였다. 연구결과 97.7%의 여대생이 결혼 후 직업 갖기를 희망하였고, 52.8%는 시부모와 별거를 희망하였으며, 48.5%는 부모부양 시 '형편에 따라 책임진다'고 하였고, 91.8%는 노인부양의 주된 책임을 가정이 지되, 국가가 지원하는 것이 바람직하다고 생각하는 것으로 확인되었다. 여대생의 노인부양의식은 평균 115.50점으로 파악되었고, 노인에 대한 지식점수는 평균 10.21점, 정답률 40.9%로 나타났으며, 노인에 대한 태도는 평균 84.19점이었다. 여대생의 노인부양의식은 종교, 한 달 용돈, 제사지내기의 여부, 장래 부모부양, 장래 시부모동거, 이상적인 부양형태에 따라 유의한 차이가 있었고, 부-조모 관계, 모-조부관계, 모-조모관계, 모-외조부관계가 좋은 경우 그렇지 않은 경우보다 노인 부양의식이 높았다. 또한 여대생의 노인에 대한 지식이 많고 태도가 긍정적일수록 노인부양의식수준이 높았다. 따라서 여대생은 노인부양과 관련하여 전통적인 가정의 역할을 중시하면서 경제적 활동에 참여하길 원하여 갈등의 상황에 직면할 수 있고, 이들의 부양의식에는 부모와 조모 간의 관계가 좋은 경우, 노인에 대한 많은 지식과 긍정적 태도가 관련됨을 알 수 있었다. 가정과 국가, 세대 간 갈등이 우려되는 상황 속에서 여성의 역할이 중요하므로 본 연구를 바탕으로 여대생뿐 아니라 전체 여성을 대상으로 하는 지속적인 연구와 관찰, 인식전환, 교육 및 사회통합을 위한 관리프로그램 개발이 필요하다.

경체 침체와 고용 없는 성장 산업으로 인해 대학생의 실업 문제가 점차 사회문제로 부각되고 있다. 특히 대학생의 취업률 문제가 대학의 평가로 이어질 정도로 정부가 관심을 갖고 대학생 취업률을 올리고자 노력하고 있다. 따라서 대학의 취업 정책은 졸업자의 취업지원을 위해 다양한 프로그램을 준비하여 대학생 취업을 지원하고 있다. 그러나 대학의 취업지원 활동의 의도, 추진 성과, 준비성 등과 대학생이 인지하는 만족도, 효용성 등 부문에서 일부 차이를 보이고 있다. 이는 활동의 효과에도 문제가 있지만 프로그램 추진의 효율성도 떨어져 예산 낭비로 이어지고 있다. 본 연구는 이러한 대학 취업 지원활동의 효율성과 효과성을 높이기 위해 대학의 지원활동에 대한 대학생의 인지도, 활용도, 만족도 등을 분석하여 대학의 취업 지원 프로그램 수정 제안과 함께 관련 주체들의 바람직한 태도와 정책을 제시하고 있다.

Students experience science not only through school science lessons but also through various other channels. Science-related facilities, including science museums and centers, are important channels for informal science education. Korea has a number of governmental and private facilities in which young people can experience various aspects of scientific activities, and many of them also provide the programs supporting out-of-school science activities. However, there has been no systematic survey study on those facilities providing out-of-school activities, thus they have not been used effectively as well as their social utility is not fully realized. To this end, in 2002 researchers of this study carried out surveys (1) of the facilities supporting out-of-school science activities and (2) of science programs provided by these facilities. The surveys show that there are approximately 180 facilities supporting science activities in Korea. More than 40% of them are located in Seoul and Gyeonggi areas. Among them, the proportion of special theme science museums was the greatest (37.9%). The facilities supporting out-of-school science activities usually do not target the specific age groups but are intended for all people. The proportion of governmental facilities exceeds that of private ones. 41.8% of the facilities examined in this study run their own science activity programs. Among the 10 categories of the programs, 'science class' type programs were the most common. There were more programs for elementary and middle school students than preschoolers, high school students and adults. The contents of the programs were more related to astronomy and meteorology, the observation of living things and field trips. Despite their high practical potential, the special theme science museums were found to be lacking in relevant programs, which could fulfill their values for informal science education.

Purpose: The purpose of this study was to evaluate the pattern and the magnitude of stress distribution in the supporting tissues surrounding three different types of implants(ITI, 3i. and Bicon implant system) Material and method: Photoelastic models were made with PL-2 resin(Measurements Group, Raleigh, USA) and three implants of each kind were placed in the mandibular posterior edentulous area distal to the canine. For non-splinted restorations, individual crowns were fabricated on three titanium abutments. For splinted restorations, 3-unit axed partial dentures were fabricated. Photoelastic stress analyses were carried out to measure the fringe order around the implant supporting structure under simulated loaded conditions(15 lb. 30 lb). Conclusion: The results were as follows; 1 Regardless of the implant design, stresses were increased in the apex region of loaded implant when non-splinted restorations were loaded. While relatively even stress distribution occurred with splinted restorations. Splinting was effective in the second implant. 2. Strain around Bicon implant were lower than those of other implants, which confirmed the splinting effect. The higher the load, the more the stress occurred in supporting tissue, which was most obvious in the Bicon system. 3. Stress distribution in the supporting tissue was favorable in the ITI system. while the other side of 3i system tended to concentrate the stress in some parts.

The review of known decisions showed that currently there are no systems and technologies for supporting the decision about the possibility of concluding the civil law agreements for medical, therapeutic and dental services. The paper models the decision-making support process on the possibility of concluding the civil law agreements for medical, therapeutic and dental services, which is the theoretical basis for the development of rules, methods and system for supporting the decision about the possibility of concluding the civil law agreements for medical, therapeutic and dental services. The paper also developed the system for supporting the decision about the possibility of concluding the civil law agreements for medical, therapeutic and dental services, which automatically and free determines the possibility or impossibility of concluding the corresponding civil law agreement for the provision of a corresponding medical service. In the case of formation of a conclusion about the possibility of concluding the agreement, further conclusion and signing of the corresponding agreement takes place. In the case of forming a conclusion about the impossibility of concluding the agreement, a request is made for finalizing the relevant agreement for the provision of the relevant medical service, indicating the reasons for the impossibility of concluding the agreement - missing essential conditions in the agreement. After finalization, the agreement can be analyzed again by the developed system for supporting the decision.

Purpose: This study was to propose the clear understanding for stress distribution of supporting bone by use of staggered buccal offset tripodal placement of fixtures of posterior 3 crown implant partial dentures. We realized posterior 3 crown implant fixed partial dentures through finite element modeling and analysed stress effect of implant arrangement location to supporting bone under external load using finite element method. Method: To understand stress distribution of 3 crown implant fixed partial dentures which have 2 different arrangement by finite element analysis. In each model, for loading condition, we applied $45^{\circ}$ oblique load to occlusal surface of crown and applied 100 N for 3 crown individually(total 300 N) for imitating possible oral loading condition. at this time, we calculated Von Mises stress distribution in supporting bone through finite element method. Result: When apply $45^{\circ}$ oblique load to in-line arrangement model, maximum stress result for 100 N for each 3 crown 47.566MPa. In tripodal placement, result for 1mm buccal offset tripodal placement implant model was maximum distributed load 51.418MPa, so result was higher than in-line arrangement model. Conclusion: In stress distribution result by placement of implant fixture, the most effective structure was in-line arrangement. The tripodal placement does not effective for stress distribution, gap cause more damage to supporting bone.

A recent High Court's decision regarding the withdrawal of life supporting medical treatment (artificial ventilator) from an elderly female patient in the terminal stage has opened up a new era of the "euthanasia dispute" in Korea. With this decision, the legitimate withdrawal of life supporting treatment became possible under certain conditions and the Korean Medical Association is working toward the establishment of practical guidelines for the terminal-stage patients. However, there are still very few debates on the cases of pediatric patients in the terminal stage or suffering from fatal diseases. For pediatric patients, the core principle of autonomy and following procedure of "advance directives" are hardly kept due to the immaturity of the patients themselves. Decisions for their lives usually are in the hands of the parents, which may often bring out tragic disputes around "child abuse", especially in Korea where parents have exclusive control of the destiny of their children. Some developed countries such as the U.S.A., the U.K. and Canada have already established guidelines or a legal framework for ensuring the rights of the healthcare system regarding children suffering from severe illness, permitting the withdrawal of Life supporting medical treatment (LSMT) in very specific conditions when the quality of life of the children is severely threatened. For the protection of the welfare and interest of the children, we should discuss this issue and develop guidelines for the daily practice of pediatricians.

본 연구 논문은 육군 전술C4I체계 지원을 위한 전문가시스템 프레임워크를 제시하기 위한 것이다. 한국 육군은 사단급 이상 부대의 전투상황실에서 수작업으로 실시하던 전장정보분석 업무를 지원하기위해 일명 "상황위협평가전문가시스템(STAFS)"개발을 실시한 바 있다. 그러나 기 개발된 STAFS는 종합적인 전투상황실 운영 개념에 부합하는 의사결정체계 구조에 맞추어 개발된 것이 아니고 전술지휘본부 내 임무 중 극히 일부분인 정보융합분석만을 위한 시스템으로 개발되어 실 업무 활용에 많은 제한을 가져 왔다. 따라서 본 논문에서는 이러한 제한점을 개선하여 전투상황실 업무를 종합적으로 지원하는 전문가시스템 프레임워크를 정립하여 지휘관의 의사결정을 지원하기 위한 전문가시스템 개발 구조를 제시하였다.
