Recent advances in network infrastructures, sensors, and IoT devices have accelerated the research and development of monitoring and interaction technologies designed for people, buildings, and environments. In particular, there has been an increasing demand for monitoring technologies for vulnerable people such as the infirm, disabled, and children. In this paper, we propose an efficient hospital room management system based on IoT care robots. The status of hospital rooms can be monitored and controlled more efficiently and intuitively by utilizing IoT devices and a cloud platform. We demonstrated the feasibility of the proposed system through the implementation of a prototype based on ARTIK IoT devices and the ARTIK Cloud platform. We found that the proposed system requires approximately 600 ms and 130 ms to collect sensor data and respond to alerts, respectively, which demonstrates it can operate in real-time.

Distributed generation(DG) of combined cooling, heat, and power(CCHP)has been gaining momentum in recent year as efficient, secure alternative for meeting increasing energy demands. This paper presents the energy performance of microturbine CCHP system equipped with an absorption chiller by modelling it in hospital building. The orders of study were as following. 1)The list and schedule of energy consumption equipment in hospital were examined such as heating and cooling machine, light etc. 2) Annual report of energy usage and monitoring data were examined as heating, cooling, DHW, lighting, etc. 3) The weather data in 2007 was used for simulation and was arranged by meteorological office data in Daejeon. 4) Reference simulation model was built by comparison of real energy consumption and simulation result by TRNSYS and ESP-r. The energy consumption pattern of building were analyzed by simulation model and energy reduction rate were calculated over the cogeneration. As a result of this study, power generation efficiency of turbine was about 30[%] after installing micro gas turbine and lighting energy as well as total electricity consumption can be reduced by 40[%]. If electricity energy and waste heat in turbine are used, 56[%] of heating energy and 67[%] of cooling energy can be reduced respectively, and total system efficiency can be increased up to 70[%].

The purpose of this study is to analyze and explain the formation and character of presbyterian missionary architecture in Andong area from 1900 to 1945, which we may call "the modem architecture of Korea". I have surveyed and analyzed the 26 buildings. and so, the major findings of this study are as follows. Firstly, the phase of building is 1) buy the existing Korean traditional building and lot-a thatch roofed house. 2) modify the existing Korean traditional building-a thatch and tile roofed hose. 3) build the Korean style building-a thatch and tile roofed building. 4) build the Western style Building-a timber structured and zinc roofed building. 5) build the Western style Building- a masonry structured and zinc(or tile)roofed building. Secondly, the character of building is 1) In the Korean traditional building, the missionaries change the function for their purpose-office, church, school, hospital. they modify the existing Korean timber frame construction by introducing the material-brick, plaster, glass, Japanese style timber etc .. they live in the Korean existing residential area. 2) In the Western style building, the missionaries build the house according to their life style. they build the timber structured building-church, and the masonry (brick or stone)structured building such as a house, church, school and dormitory, and hospital. their building located on the hill depart from the existing Korean residential area.

The purpose of this study is to reveal the meaning of ramp of Le Corbusier's Carpenter Center for the Visual Arts focused on experience of architectural promenade. The Carpenter Center was completed in 1964, only a year earlier than the death of Le Corbusier and also, this building is the only building actually constructed in North America. Despite these important facts, the meanings of the ideas of this building have not been paid attention as much as other buildings constructed at the same period, such as, Venice Hospital and Un Pavillion D'exposition in Zurich. In his book, 'Oeuvre Complete 1957-1965', Le Corbusier mentioned Carpenter Center as an architectural experiments of his ideas. The study of carpenter center will be an important architectural subject to clarify the meaning of his later works and ideas.

The Korean hospitals have been changed a lot from 1970's to 1990's, not only in their space allocation but also in their functions. These changes were affected by the medical development, social atmosphere, increasing population, needs of medical demands, and so on. In this study, we compared net area allocation involve in these affect of hospitals which were built in 1970's, 80's, and 90's, and through this comparison, we analyzed developing tendencies of hospitals. In doing so, we tried to provide basic research data for planning of new hospital buildings.

Wards are the biggest part in hospital buildings and the flow of medical personnels and materials is an important factor in the ward design. The evaluation method of the wards and is esscential for the optimum design considering function, environment, patient psychology, etc. To achieve this goal, factors for evaluation of wards were introduced and then each factor was systematically analyzed. A evaluation method are developed from studied factors and are applied to existing wards to check the reliability. The selected evaluation factors are limited to the privacy of patient, the functional efficiency of operation, and the economy of wards.

Termites are destructive to agriculture, forestry, and buildings, but they can also promote agro-ecosystem balance through the degradation of lignocellulose. Termite-triggered cellulose digestion may be clarified through microbial metabolism of cellulose products. In the present study, we characterized the activities of cellulase and its three components synthesized by the cellulase-producing fungal strain HDZK-BYTF620 isolated from the gut of Odontotermes formosanus. The protein components of cellulases were synthesized by strain HDZK-BYTF620, which were isolated and characterized using polyacrylamide gel electrophoresis, and the expression of the cellulases was studied at the proteome level.

In considering the issue of safely during emergency building evacuations, it is important to be able to make accurate predictions about evacuation conditions and to be able to assess safety levels. Simulation techniques are often used to make predictions regarding evacuation conditions. The two main types of prediction models are crowd flow models and discrete models. We have developed an evacuation simulation system based on the discrete model which attempts to address the implementation problems of existing evacuation models. Our model incorporates characteristics such as evacuee profiles and spatial considerations, and is capable of dynamically predicting the behavior of individual evacuees. The simulation system is primarily designed for buildings in which many people are incapacitated and require helpers in order to evacuate, such as hospitals and facilities fur the elderly. We show the results that the evacuation simulation system was used to perform two trial simulations.
