Character and illuminance distribution of daylighting is very important for the architectural plan in museum. Those data show bases for exhibition space design with daylighting and play a decisive role in visual perception of articles and space aesthetic. The goal of this paper was therefore to analyze the illuminance distribution in fine art museum with 3 typical girdle skylight types which are devided according to the art of protection from glare. This Experiment proved that they had a striking contrast with regard to the ratio of daylight illumination and illuminance distribution in spite of the same purpose of those development. The girdle skylight with a translucent glass showed the strongest value of the ratio of daylight illumination, but inequable illuminance distribution in space, excepting the area of the wall. However, the latticed reflector of light refracted daylight in the direction of wall and made illuminance distribution very equable in whole space. The ratio of daylight illumination at the girdle skylight which was located at the verge of the ceiling, was highest at the upper part of the wall and was reduced gradually from there, by way of the middle and under part of the wall, to the center of space.

Lighting in the tunnel makes for safe driving of cars taking into account of change in perception arisen in the sight of drivers of cars entering into and passing tunnel, drivers' mental reaction and unique circumstances of a tunnel. There are many variables to satisfy safe driving in the tunnel. Since tunnels are mostly located in the mountainous area and illumination at the approach part differs largely depending on the surrounding circumstances, a standard different from that of common lighting is applied. An accidentin the tunnel, which involves same danger as in underground, may lead to a large mishap. Therefore, control by sensors inside and outside of tunnel ensures prevention of an accident through control of illumination at the approach part and inside of tunnel. It is very important in the aspect of saving energy since such control is available to reduce depreciation factor resulted from early excessive intensity of illumination.

The purpose of this article was to study the influence of eco-friendly management on customer's purchasing-intention at franchise Korean restaurants. In this research, factor analysis and multi regression analysis were used. Eco-friendly management was divided into 4 factors. Eco friendly service affected positively brand image (p<0.05). Energy saving positively affected brand image (p<0.005). Contribution to local society positively affected brand image (p<0.05). Menu composition affected the most positively brand image (p<0.001). At last, brand image had positive influence on purchasing intention (p<0.001). According to these results, we confirmed that the factors of eco friendly management influenced significantly on the customers' perception of brand image. As a result, food service corporations need to deal with the factors of eco friendly management efficiently. The findings of this research would help business management to build effective service marketing strategies and to satisfy the needs of customers at franchise Korean restaurants.

The application of Internet technology has created enormous impact on banking sector with the implementation of many techno-oriented services like Internet banking, EFT, branchless banking, Automated Clearing House (ACH) transactions etc. Study of customer's attitude in terms of trust, perceived risk and ease of use of a particular technology is as an important parameter for acceptance or rejection of a technology. To explore the customers'attitude for Internet banking this research is undertaken. The research is carried out in Pokhara valley which is the second largest city and tourism capital of Nepal. The study employs descriptive research design with stratified sampling procedure for eight top commercial banks. A set of 25 customers is taken from each selected 8 banks making a sample size of 200 respondents. A fixed set of question related to demographic factors is provided personally or by visiting the location of the customers of Internet banking service and collected accordingly. Reliability test is performed using Cronbach's alpha and data is analyzed using inferential statistics to present the results of the study. This study provides knowledge on the current scenario of Internet banking and helps banks in cost saving, mass customization, product innovation, improved marketing and communication. This study is very important for financial institutions like banks, government agencies and business houses to understand the perception of customers towards Internet banking and technology as a whole. The study also supplements the gap in literature on technology and banking in Nepal and serves as an important knowledge base.

The purpose of this study was to find out awareness of the environment-friendly planning elements for residential unit space among practitioners. The respondents in this questionnaire survey were 140 practitioners in architecture and interior design field. The major findings of this study were as follows; most of the respondents were aware of the impact of indoor built environment on residents' wellness. In addition, the survey respondents viewed that the factors for planning environment-friendly high-rise apartments were represented by gardening and energy-saving while their perception on the concept excluded comprehensive components affecting residents' life quality. Over 50% of respondents had an experience of applying environment-friendly planning elements in their works, and high frequency appeared on the general planning elements which had been applied special awareness as pro-environmental features. The respondents considered environment-friendly planning elements as important. Specially, space planning and system were considered more likely important in interior design field. In application of environment-friendly planning elements, cost, lack of consumers' awareness of and underdevelopment of environment-friendly materials were of concern. Therefore, the consumer's cognition needs to be improved for wide application about environment-friendly planning element, and then consumers are willing to pay additional construction cost of environment-friendly apartments. At the same time, the current practice that housing developers pass the additional cost on to residents needs to be changed. Then, the quality of life in high-rise residential settings can be improved. More importantly, the exchange and development of the reliable information on environment-friendly planning elements need to be made, and technical support and long-term policy for the development are required. This research showed current status of knowledge and practice in sustainable planning of unit apartment and proved basic information for future direction.

가시광 무선통신은 LED의 깜박임(ON/OFF)을 이용한 통신 방식으로, 인간의 시신경 인식의 한계로 조명의 기능도 유지된다. VLC 시스템에서 사용되는 LED의 밝기 조절은 에너지 절약과 생활 혜택을 제공하는데 필요한 중요한 요소이다. 또한, VLC 시스템이 발전하면서 MIMO 기술은 안테나 수에 비례하는 채널 용량을 얻을 수 있다는 점에서 큰 주목을 받아오고 있다. 이에 본 논문에서는 VLC 시스템의 MIMO 방식 중 하나인 RC방식으로, 4개의 변조 방법인 RZ-OOK, VPPM, MPPM, OPPM을 사용하여 디밍에 따른 통신 성능을 분석하였다. 이에 대해 시뮬레이션 한 결과, 4개의 변조들 중 power requirement 측면에서는 MPPM 변조가, spectral efficiency와 bandwidth requirement 측면에서는 OPPM 변조가 성능이 좋음을 확인하였고, 디밍에 따라서 각 변조들의 통신 성능이 달라짐을 확인하였다.
