During that time various methods were introduced in the unit planning for the various realization. But the consideration against a variety from the living and functional side still is insufficient. The methods of this study are as follows: 1) Executing domestic instances of being completed above 30 years apartment housing. 2) Case studying the 'Wallgae mansion' in hannam-dong, one of them. Based on the results, this study is analyzed plan variations and the changing points of exterior elevations. The results are as follows: The layout integrated and divided changes composition of units and it is various escaping in the outer wall as the external space being various. Also including the balcony, the spaces with intermediate characteristics much more effect variety of elevations.

In this paper, I try to measure the electrical characteristics of PV cell for lanterns with solar simulator and simulated with PC1D software. I keep my eye on the characteristics variation of PV cell as a temperature change. Therefore, I try to increase a temperature of controlled block from $10^{\circ}C$ to $50^{\circ}C$ while measuring the PV cell. As a result, A variation caused by voltage have an effect on the efficacy of PV cell. Hence, it is an important variable when a designer plan to make a solar cell for lanterns.

In this paper, I try to measure characteristic transmission-reflection by environmental change or solar cell. I keep my eye on the characteristics variation of solar cell as environmental change. As a result, A variation caused by voltage by an effect on the efficiency of solar PV cell. Hence, it is an important variable when a designer plan to make a solar cell.

I keep my eye on the characteristics variation of PV cell as a temperature change. Therefore, I try to increase a temperature of controlled block from $10^{\circ}C$ to $50^[\circ}C$ while measuring the FV cell. As a result, A variation caused by voltage have an effect on the efficacy of PV cell. Hence it is an important variable when a designer plan to make a solar cell for lanterns.

As the new variation malicious codes of android platform are drastically increasing, the preparation plan and response is needed. We proposed a high-interaction client honeypot that applied to the android platform. We designed flow for the system. Application plan and the function was analyze. Each detail module was optimized in the Android platform. The system is equipped with the advantage of the high-interaction client honeypot of PC environment. Because the management and storage server was separated it is more flexible and expanded.

In order to ensure the safety of a structure, it is essential to put in practice all sorts of measurement from the plan and execution to the management by stages. These measurements make it possible to verify a propriety of a plan and forecast an accident or a collapse caused by long lapse of time, making use of accumulated data. Close-Range Photogrammetry is a method to meet improvement and development of surveting technique. which offered data for maintenance and management of a structure. Dus to applying this way. reliance on measuring a variation of structure. Besides, data of variation will be utilized for maintenance and management of a structure.

The purpose of this study is to seek out the harrow water requirement applicable for the irrigation plan of paddy field and to find out the factors influenced on a variation in the requirement. The plots of experiment were arranged with randomized block design which was compo- sed of three kinds of soil texture (sandy loam, loam and silty loam) and ploughing depth (12cm, 17cm, and 22cm). The results obtained from this experimental study are summarized as follows. 1. Harrow water reguirement is not only changed by soil texture, but influenced by soil water content just before irrigating 2. Magnitude of total harrow water reguirement appli(able for the irrigation plan, when surface water depth and the water content just before irrigating is fixed on the basis of 30 mm and a shrinkage limit respectively, generally becomes to be 177.5mm, 116.3mm and 113. 8mm in the sandy loam, loam amd silty loam block, respectively. 3. The more a percolation of soil layer occurs, the more the harrow water requirement increases, but it is not much influenced by the increase in ploughing depth. 4. The larger a porosity of soil layer is, the more a net harrow requirement increases 5. The factors that influence on a variation in the harrow water requirement are appea- red to be percolation of soil layer, soil water content just before irrigating, porosity of soil layer, ploughing depth and designed surface water depth etc.

A total of 2,325 schools including all of the middle and high school have operated variation type since government announced the "Variation Type classroom System Promotion Plan" in May 2009. New education policy, free learning semester of middle school, was introduced after current government took office, followed by extended application of educational policy. Korean students have a low level of happiness and interest in the school due to admissions intensive competition and the investment memorize education and cramming education. Therefore, in consideration of youth development stage, free learning semester system introduction commitment was announced in November 2012, and free learning semester was operated by way of showing an example in 2013, and then expansion implementation plan of 2015 was established, because free learning semester introduction in middle school stage is increasing. This study considers concept and operation method to free learning semester of middle school which are newly introduced, based on the policy documents of Ministry of Education. Also, through the example of Japanese schools, this analyses creativity, personality, social skills, and healthy corresponding to a free learning semester curriculum of middle school, and present method to apply for Korea.

The purpose of this study was to analyze the Characteristics of Flexible housing Unit Plan Choice. It is believed that Flexible Housing relates to Family life cycle and the number of family. But this study revealed another factor, Space Syntax. It is reviewed that the Space Syntax effectively reveals the relative spatial depth of the spatial elements composing flexible housing unit plan. Thus, the Space Syntax is adopted as an analytic method of this study to objectify the concrete spatial changes. Through this study, the spatial organization of each case before changing is compared wi th that after changing, to find out the spatial changes over variation, Based on this theory, this study provide basic data to be used for architectural planning for flexible design. To design common facilities that support residents' leisure activities is one of the contemporary issues in Korea. People became interested in the leisure facilities in near-home environments. This trend encouraged this research study. The objectives of this study are to analyze the current status and characteristics of leisure facilities in apartment communities, to examine the correlations among leisure facilities, and to suggest design considerations for korean multi-family housing communities.
