본 논문에서는 최근 발생되는 기상이변의 원인인 에너지의 과도한 사용을 감소시키기 위하여 사용자가 인지하지 못하는 동안 낭비되고 있는 대기전력을 자동으로 제어하는 시스템을 구현하였다. 현재 사용되고 있는 대기전력 제어 시스템의 경우 일정 전력 이하의 전력량이 감지되면 자동으로 차단하는 형태로 운영되고 있으나 재가동을 위해서는 사용자의 수동 제어에 의존해야 하는 불편함이 발생한다. 이에 본 논문은 사용하지 않는 가전기기의 대기전력을 차단할 뿐만 아니라 사용자의 편의성을 고려하여 자동으로 전력을 재공급하는 대기전력 컨트롤러를 구현한다. 기기의 전력 재공급은 각 사용자별 기기 사용패턴을 고려하여 구현하였으며, 이때 사용자의 구분은 2개의 Ultrasonic 센서로부터 산출된 사용자의 키와 무게 감지 센서로부터 산출된 사용자의 몸무게를 활용하였다.

Objectives : External form and internal intersection of Phragmites communis were observed by the parts of usage (leaves, stems, and roots). Methods : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and then observed and photographed by olymphus-BHT. Results : 1. The intersection of Phragmitis Folium was typically characterized as Gramineae plants, which was perfectly distinguished with Phragmitis Rhizoma and Phragmitis Caulis. 2. The cortex of Phragmitis Rhizoma has a large rectangular pore space, but Phragmitis Caulis does not. Conclusion : Phragmitis Folium, Phragmitis Caulis, and Phragmitis Rhizoma can be distinguished by microscope.

In this study, the chamber size was designed and manufactured so as to make a resonance with microwaves in sterilizing moisture-contained food by making good use of microwaves. When the green-pea jelly which was made and sterilized for experimental usage with no addition of an antiseptic was left in the room temperature for 1 minute, 2 minutes or 3 minutes respectively, resulted in delaying more greatly the procession of change in quality of food for almost 7 to 15 days than in unsterilized food. As a result of experiment conducted above, it is considered to produce good results of decreasing the resource waste and environmental pollution, by lengthening the period of preservation and circulation of food.

This study purposed realization and a phase reduction of school building $CO_2$ emissions. Accordingly selected standard school buildings and evaluated life cycle environmental load($CO_2$). This study proposed Green building technology which separated design sector, energy sector, afforestation sector for carbon-neutral city school buildings realization of M-city. As a result, elementary, middle and high schools of M-city built in the year 2013 were required that design sector was Energy Performance Index(EPI) 75 point and energy sector was solar installations more than 25% of the power usage, Solar systems installed more than 10% of total gas consumption and the area of afforesting more than 35% of the ecological area to achieve 30% $CO_2$ reduction compared to the Respectively standard school buildings.

Recently, housing consumers are demanding new types of residential housing and environmentally friendly housing. I think that the related issues and problems can be solved by introducing various types of independent housing. Garden is an important space for single family housing, providing calmness and restfulness etc. Furthermore, it provides a green space for our city. According to the result of this paper, I would like to suggest some important conclusions. 1) Residents in single family housing want sufficiently large garden space and they need good design of planting. 2) They are interested in gardening. They also want to have various ideas and information for gardening and need useful skills to prevent their garden from insects and diseases from the garden maintenance companies. 3) Generally, they want to design their garden for the usage of their relaxation and ornamental enjoyment.

Objective : "Sikryochanyo"written by Jeon Soonyi is the first food-Therapy book at Korea. In "Sikryochanyo", there are many kinds of food-Therapy including Five-Vegetable therapy. Method : We will try to find out cases of food-therapy with Five-Vegetable in "Sikryochanyo". Result : In "Sikryochanyo", Five-Vegetable were treated as materia medica widely. Green onion, one of Five-Vegetable as materia medica was the major in use and porridge or soup were the major in frquency. Conclusion : On several types of Five-Vegetable, such as parts or whole, methods to make, the prescription shape etc., there are plenty of usage with its own effectiveness.

This paper is focused on studying a pedestrian passage that forms exterior space of the housing unit on diverse prerequisites and convenience of residential environment regards to plans for Multi-family Housing Complex. The paper explores the actual usage of a pedestrian passage installed in Multi-family Housing Complex and examine whether the nature-friendly space that includes the exterior pedestrian passage of the housing unit is being applied variously on a pedestrian passage. In order to obtain an analysis of the current status on case study unit, the study has prepared an analyzing tool for the environment in use for the exterior pedestrian passage and was able to construction problematic points by applying the obtained data. Thanks for the analysis, a comprehensive evaluation on the plans for the pedestrian passage was implemented through correlation with a green tract of land, living space and the exterior pedestrian passage installed in Multi-family Housing Complex.

In this paper, the management system for a bicycle station using 900 MHz RFID technology has been developed. Based on the several reasons such as environmental pollution, high oil prices, and the government's eco-friendly policies, a bicycle usage is increasing nowadays. Accordingly, a need for bicycle parking spaces has already been emerging and increasing around a bicycle station. But most of the bicycle parking system are operated by manually, and it causes somewhat inefficient. Therefore, this paper suggests an unmanned bicycle station using RFID technology. The proposed system is supported by the mobile applications that are operated in the smart phones, and which gives the real-time access to the information of bicycle station. The proposed system yields owners of bicycle owners the convenience and efficiency of the station management in order to maximize the function of the bicycle stations.

The aquatic fern Azolla spp. is of value as a bio-fertilizer for wetland paddy, and also can be used as an ideal feed for cattle, pigs and poultry. It is popular and cultivated widely in other countries like China, Vietnam, and the Philippines, but has yet to be taken up in Korea, in a big way. It fixes nitrogen as high as 3-5kg N per day, because it contains nitrogen fixing blue-green algae, Anabaena azollae. Azolla's ability to create a light-proof mat that suppresses other weeds has been used for centuries in rice production. Azolla spp. has also the capacity to take up the heavy metals ($75{\sim}100%$) and may be used as a bioaccumulator. Moreover, Azolla meal as an unconventional feed resource has a potential as a feedstuff for livestock.

The purpose of this study was to investigate the outdoor space of the recent built apartment complex in Ulsan and to provide the basic information for planning and apartment outdoor space. Multiple methods were utilized such as questionnaire, observation, behavior-mapping, and photography. The sample consisted of 382 residents living in four apartment complex in Ulsan. data were analyzed by frequency and percentage using SPSS PC+. The observation was performed in seven outdoor space, i.e., green area, road area, exercise area, play area, parking area, and approach area. According to the findings of this study, residents did not actively involve in outdoor activities and seldom use the outdoor space. Various changes and erosions were observed as a trace, especially near fence and grass area because of unplanned location of entrances. Finally this study suggested several planning guidelines for outdoor space in apartment complex.
