Medilog SAC847 수면종합분석시스템을 이용하여 침대와 온돌에서 성인 남 자가 수면시 피험자의 뇌전도, 턱근전도, 다리근전도, 심전도, 안전도(눈) 등의 생리신호를 동시 측정하여수면단계기록국제기준에 근거하여 NREM 4단 계와 REM 단계의 수면시간을 산정 하였다. 수면감을 평가하기 위하여 침대 와 온돌에서 수면시 입면지연시간과 NREM 단계4의 수면시간 비중을 고찰한 결과 침대수면이 온돌수면보다 입면지연 시간이 더짧게 나타났으며 나머지 NREM 4단계와 REM 단계에 소요된 수면시간은 서로 비슷하게 나타났다. 본 연구를 통한 수면생리신호 분석연구는 쾌적침대개발에 활용하고자 한다.

This study aims to understand students' perceptions of the spatial characteristics of school libraries when they use them for reading. We selected a set of spatial characteristics by reviewing the literature and conducting a preliminary investigation. Then, we examined how students perceived the importance of and how satisfied they were with each characteristic. In addition, we investigated how students' perceptions differ by the library uses and reading-related activities. We also studied whether the satisfaction of school library users affects their continued use of the libraries. We also verified whether school library user satisfaction is an intervening variable in continued-use intention, which is affected by spatial characteristics perception. We conducted a survey of 342 students from four middle schools. The analysis of the survey outcomes shows differences in library use due to spatial characteristics such as convenience, communicability, diversity, and safety. Factors such as communicability, comfortability, and ambience affected user satisfaction positively. Both aesthetics and communicability also positively influenced the continued-use intention. Furthermore, we identified that communicability, comfortability, and ambience eventually impacted the continued-use intention via user satisfaction, an intervening variable. The significance of this study is that it considered the direction of the school library to support students' reading by regarding the school library as a space for reading.

The object of this study was to develop an index of service quality of waterparks and verify the validity and reliability of the index. This study represents the waterparks user population in 2009, and 250 people were extracted by using the purposive sampling method. In other words, five locations have major waterparks were chosen and 50 people per each location were collected. Conference, panel survey, exploratory factor analysis and confirmatory factor analysis were performed to verify the validity of the questionnaire while item analysis, interrater reliability and internal consistency reliability were conducted to probate the reliability. Through these methods and procedures, the results of this study like these; (i) Validity of this index was significantly high and the index include amenity/cleanness, safety, price, programs, facilities, accessibility and promotion. Among them, amenity/cleanness was the major factor for the validity value; (ii) Reliability of this index was also high. There are high correlations between questions and fields and questions and total score. And the Cronbach's $\alpha$ values of the internal consistency reliability was over 0.603 except in the case of promotion which was below 0.6. After all the analysis, the index of service quality proved to be very proper and reliable index. Therefore, the major factors of service quality have to be figured out and reflected to the management innovation to improve service quality of waterparks.

This study addressed the process to construct, operate, verify the test beds, which had been equipped with a variety of core technologies such as WAVE, Road-Radar, Smart Tolling developed by Smart Highway Project. We have met our research goals, but there were limitations to secure the performance and user feedback because of small scale and short operating time. So, we will enhance user safety, convenience and comfort by accumulating and analyzing big data then improving testbeds and related technologies through subsequent research projects for a long time.

최근에 각종 SOC사업이 본격화되면서 고속도로망 및 도시교통망 확충이 가속화되어 장대 터널이 급증하고 있을 뿐만 아니라 차량의 급속한 증가로 차량배기가스에 의한 터널내부 환경의 악화가 문제시되고 있다. 특히 도로터널은 반밀폐 공간으로 터널내에서의 사고는 인명피해와 막대한 재산 피해로 이어질 수 있으므로 안전운전을 위한 제반설비 및 대책이 필요하며 안전운행을 위한 가시거리 확보 및 쾌적한 환경에 대한 요구가 대두되고 있다. 따라서 터널에서 이와 같은 요구를 만족하기 위해서 기계환기설비가 투입되고 있으며 이에 대한 최적화 설계에 대한 필요성이 높아지고 있다.(중략)

고속도로를 주행하는 차량에 작용하는 순간적인 강풍은 차량의 주행경로이탈, 차체의 수평회전 과다와 전도를 발생시키는 원인이 되며, 이로 인한 교통사고는 치명적인 대형사고로 이어질 가능성이 높다. 최근에 건설되거나 추진중인 고속도로는 고속운행에 필요한 도로선형을 확보하기 위해 계곡부를 통과하는 높은 위치에 교량을 건설하거나 산악터널을 내는 경우가 많으며, 지형적인 특성으로 발생하는 국지적인 강풍의 영향이 매우 크기 때문에 적극적인 강풍저감대책이 필요하다. 본 연구에서는 강풍 발생지역을 주행중인 차량의 안전성 및 쾌적성확보를 위하여 차량의 동역학적 거동을 규명하고 차종별 주행속도와 순간풍속의 상관관계를 정립하였다. 또한 차량사고의 영향인자별 분석을 통하여 기존에 제시된 연구결과와 기준안에 대한 고찰을 실시하였고, 강풍발생 지역을 통과하는 차량에 대한 규제와 운영방법에 대해 위험풍속을 정의하고 차량속도규제(안)을 제시하였다.

As car-oriented road policies have been made forward so far, relatively pedestrians' walking conditions are so in poor environments that more than two thousand pedestrians die from car accidents every year. Pedestrians' walking right has been severely invaded like that. Pedestrians' walking right is a right that people are able to walk safely and comfortably in pleasant surroundings as long as they don't threaten the public safety, order maintenance, and welfare. The government has an obligation to provide safe, comfortable, and pleasant environments to pedestrians. Recently interests in pedestrians' safety are increasing, government-driven supports have been made to make safe, pleasant, and healthy walking surroundings. As poor walking condition improvement projects cost high, they should be progressed to accomplish maximal effects using finite finances efficiently, and post feasibility evaluations of the projects should be severely estimated. However site selecting indicators which satisfy with the goal for composing safe working surroundings have not been decided yet, though currently it has a legal basis to specify walking condition improvement sites by the Law for Pedestrians' safety and Comfort Increasement. Therefore this study focuses on suggesting improved ways for selecting sites where pedestrians' safe environment project by reviewing previous research. When project sites are selected, evaluation indicators related to awareness survey of residents and history should be excluded, and disaster safety assessments for walking safety facilities, latent human hazards and natural disasters like a strong wind are proposed besides evaluations on pedestrians' safety and walking environment for matching with the purpose of the project to make safe working surroundings.

The purpose of this study is to analyze the effectiveness of the community development by the community involvement level of the corporate social contribution activities. This study classified Korean company's best social contribution activities according to the community involvement level and the effectiveness of the community development was analyzed on selected case activities. As a result, corporations that working on high level of community involvement show positive effectiveness of community development. Networking and communication with local people on the corporate social contribution activities have an effect on the community development of the economy, safety, convenience, comfortability, socio-cultural factor. It is necessary for the participation and communication with local people to develop corporate social contribution consistently. Furthermore, intermediary organization is needed to be set up various networks of stakeholders, especially community.
