시트 커버 직물은 철도차량 내부 인테리어와 실내를 구성하며, 시각적으로 커버 직물의 디자인 요소 중 패턴과 쾌적한 커버지가 철도차량에 대한 전체적인 이미지를 형성하게 된다. 본 연구는 한국인의 감성에 따른 시트 패던 디자인과 쾌적한 시트 커버 직물의 요건을 제시하고자 한다. 디자인 분석체계는 패턴 디자인의 최소단위를 Pattern Primitive(PP), 최소 반복 단위를 Repealed Pattern Unit(RPU)로 개념화하여 분류하여 파악한다. 또한 쾌적하고 안락한 시트를 위해서 착석 상태에서의 열수분 전달특성과 직물의 발수도, 일광견뢰도, 마찰견뢰도, Q-max, 공기투과도, 마찰대전압 등 물리적 특성을 비교한다.

차량종적제어시스템을 이용한 운행장치에서 측정센서에 의하여 감지되는 정보량에 따른 응답특 성은 다음과 같다. 1) 종적제어시스템(longitudinal control system)을 이용하여 소대를 형성하는 과정에서 순차형 태로 정보를 전달할 때는 거리만을 이용하는 경우보다 거리 및 접근속도를 모두 사용하는 것이 훨씬 안정된 소대의 형성을 나타내었다. 2) 제어장치에서 제어상수의 선정에 따라 구분되는 세 가지의 영역이 정의되었다. 쾌적한 운행의 판단은 빠른 주기로 변화하는 응답특성이 나타나는지의 여부로 결정할 수가 있다. 즉 빠른 주 기로 감가속을 변화시켜야 할 경우에는 안락한 승차감을 기대할 수 없다.

인간은 사용의 편리성 즉 육체의 편안함과 정신의 안락함을 목적으로 기기를 개발하고 신기술들을 개발해 왔다. 이러한 기술중에서 제어에 관한 기술은 현대에 들어 급속히 발전하여 기존의 제어개념과 다른 지능제어라는 새로운 영역을 구축하고 있다. 이러한 지능제어는 각 기술별로 제품에 적용되어 왔고 또한 그 효과 및 장점에 대해서도 사람들이 인정을 하고 있다. 이 글에서는 지금까지의 개별적인 응용 외에 향후 산업계에서 지능 제어이론을 어떠한 목적으로 어떠한 방법으로 활용해 나갈 것인가를 예측하여 보고 그에 대한 고려사항들을 살펴보았다.

Urban roads are not only congested with vehicles and pedestrians, but also have many pipelines buried to provide convenience for inhabitants. In addition, urban inhabitants live comfortably in buildings adjacent to the road for residence, business, commerce, rest and so on. Therefore, despite the high cost of land, urban underground buildings with high land use efficiency are constantly being built. Recently, the construction of underground buildings has caused social problems such as the collapse of surrounding roads and adjacent buildings. Institutional improvement is being actively carried out to improve this. In this study, a new type of MSRC diaphragm wall was developed and a study on the construction method of underground building was carried out. It is intended to secure the underground excavation safety of underground buildings in urban areas and effectively prevent land subsidence complaints. Also, a reasonable design method of MSRC diaphragm walls using the ultimate strength design method is presented through the flexural performance Experiment.

본 연구는 새로 개발된 에어쿠션의자의 인체 적합성 검증에 관한 실험으로 기존 에어쿠션의자와 스펀지 매트의자를 새로 개발된 의자와 비교 평가 하였다. 본 연구를 위해 설문지를 통한 사용자의 감성 및 사용성을 측정하였고 객관적 검증에 필요한 체압분포측정을 하였다. 실험의 결과 사용성 평가에서 대부분의 피험자들이 신형 의자가 보다 편안하고 안락하다고 응답하였으며, 각 의자를 비교하는 전체 14항목의 설문 중 11개 항목이 의자A에서 중요도 순위가 좋게 나타났다. 체압분포에서도 좌판의 경우 신형 에어쿠션의자의 체압의 평균값이 적게 나오면서 고르게 분포하였고, 좌골결절을 중심으로 좌, 우 대칭이 되게 나왔다. 또한 등판부위에서도 등판의 수직선을 중심으로 체압분포가 좌, 우 대칭이 되게 나왔다.

Purpose: Sooner of later, end-of-life care decision-making will unfold and be settled during the professional lives of medical students. However, there is prevalent ambiguity and uncertainty between the palliative treatment and euthanasia. We conducted this survey to investigate attitudes of medical students towards end-of-life making decisions, and to find out which factors primarily influenced the attitudes. Methods: A study was conducted among medical students at one university, the Republic of Korea. A written questionnaire was sent to all the 1st, 2nd, and 3rd-year medical students. It presented 5 statements on end-of-life decision-making. Students were asked whether they agreed or disagreed with each statement. Results: The response rate was 74.4%, and 267 questionnaires were analyzed. Percentages of agreement with each statements on Voluntary active euthanasia (VAE), Physician assisted suicide (PAS), Withholding life-sustaining management, Withdrawing life-sustaining management, and Terminal sedation (TS) was 37.1%, 21.7%, 58.4%, 60.3%, and 41.6%, respectively. The grade of students, religious activity, and educational experience were determinant factors. Agreement on each statements was higher in the low religious activity group than in the high religious activity group. Agreement on TS was higher among 3rd year students during their clerkship than among 1st and 2nd year students. Age of students and the experience of dying-people care had no significant influence. Conclusion: In end-of-life decision-making, religious and educational factors influenced medical students' attitudes. Especially, the experience of education during clerkship had significant influence on the attitude. Proper teaching on end-of-life decisions should further be considered during medical students' clerkship.

This study aims to analyze the impact of servicescape on the perceived values and brand attitude of coffee customers. In order to archive our research objects, current study employed SPSS 22.0 statistal program. The summary is as follows. First, it was revealed that the servicescape of coffee shops has a positive influence on perceived value. Second, the servicescape of coffee shop has a positive influence on brand attitude. And perceived value of the customer has a positive impact on customer brand attitude. Based on the results, this research has concluded some theoretical suggestions as follows. First, in case of brand coffee shop, it was analyzed that the attractions of interior design color, floor and wall interior, and structure has influenced on the differentiated values of customers. Also, the accessability shows that the brand coffee shops with parking facilities along with the convenience provided by the off-site facilities make customers highly recognize the brand values. In addition, the results found that the factor of service condition becomes a determining factor. Thus, current study will contribute to consider the various elements of service scape when new business develop as well as redesign the previous stores.

The purpose of this study was to analyze the effect of environmental perception in neighborhood parks on user's recognition of health improvement. This study used objective field survey data and subjective user survey data at 8 neighborhood parks in Changwon City. According to the results, the perceptions of distance and street environment from home to park were evaluated highly but the perception of water spaces and various attractions within the parks were rated lowly in most of parks. As a result of factor analysis, 23 environmental perception variables were classified into 6 factors such as scenery, comfort, accessibility, activity, convenience and amenity. For the result of regression analysis between environmental perceptions and user's recognition of health improvement based on 6 factors, the recognition of physical health improvement was significantly influenced from environmental perception factors in 4 parks among 8 parks. 'Accessibility' and 'activity' were analyzed as the meaningful factors in 3 parks. Also, recognition of mental health improvement was significantly influenced from environmental perception factors in 5 parks among 8 parks and especially 'accessibility' was showed as the significant factor in 4 parks. The findings from this study can contribute to improve the physical environments of the present parks and can be a basic data for new park development.

The Automotive seat is the component related at passenger feeling and safety. It absorbs the impact or vibration and supplies the comfortableness. It must also have sufficient rigidity and strength to satisfy these given conditions. Two kinds of seat models are designed and studied by structural analysis. Seat back frame (b) has lower deformation and fatigue life than (a). Most deformation and damage possibility is shown at the waist, that is the middle of model. On the vibration analysis at which natural frequency is applied, model (a) has the deformation from outside to inside of model, but model (b) has the deformation from inside to outside of model. Model (b) is safer than model (a) structurally at most cases.
