The floating photovoltaic system is a new concept in the renewable energy technology. That is similar to land based photovoltaic technology except floating system. So the system needs buoyant objects, mooring, ect, besides modules and supports, and that is able to withstand in water level changes and wind strength. Therefore the floating photovoltaic system is much different from land photovoltaic system. K-water (Korea Water Resources Corporation) has been operating two floating photovoltaic system that's capacity is 100 kW and 500 kW respectively since in summer 2011 for commercial generation, and have construction project for 2,000 kW in Boryeong multipurpose Dam and other areas. Furthermore K-water was developing a tracking-type floating photovoltaic system at Daecheong multipurpose Dam and developed and installed an ocean floating photovoltaic demonstration plant at Sihwa Lake in October 2013 for R&D. In this paper, we introduce that structure of floating photovoltaic system include buoyant structure, mooring system and auxiliary device. Especially the rope which is in part of mooring should be always maintain tension under any water level. Also we explain about structure design concept to wind load in an every loading condition and a kind of structure materials and PV structure types used in water environment. Especially ocean floating PV system is affected by tidal current and typhoon. So there are considering the elements in design. Finally we compare with floating and land photovoltaic on power amount. As a result of that we verified the floating photovoltaic system is more about 6.6~14.2 % efficiency than a general land photovoltaic system.

Since the commercial operation of Kori Unit #1 nuclear power plant(NPP) started in 1978, 23 units at present are operating in Korea. Radioactive wastes will be steadily generated from these units and accumulated. In addition, the life-extension of NPPs, construction of new NPPs and decontamination and decommissioning research facilities will cause radioactive wastes to increase. Recently, Korea has revised the new classification criteria as was proposed by IAEA. According to the revised classification criteria, low-level, very-low-level and exempt waste are estimated to about 98% of total disposal amount. In this paper, current status of overseas cases and disposal method with new classification criteria are analyzed to propose the most reasonable method for estimating the amount of decommissioning waste when applying the new criteria.

The current global economy is changing from a proprietary commercial economy to a shared economy of value sharing. In modern society, single-person households have become common type of households. The reason for the increase in single-person households is due to the rising age of first marriage, the increasing number of elderly people, which is a result of the extension of the average life expectancy, fewer marriages, more divorces, goose fathers, the separation between dwellings for work, etc. Especially a significant amount of single-person households is occupied by young people, which is common in large cities. Along with the increase in the number of single-person households, the youth has created a new demand for housing demand for single-person households. The purpose of this study is to identify which factors influence the preference of a share house as an alternative to a single-person household by making an empirical analysis. As a result of the analysis, the accessibility of a share house, the characteristics of the building and the facilities all had a significant effect on the preference.

Underground distribution system is a trend due to the successive development of metropolitan area and satellite cities and the environment of the commercial and residential areas. The high quality of electricity, which is related with the minimal outage duration time due to the maintenance work for the underground distribution line, is mandatory. Hence, the construction method and tools for the outage-free maintenance construction have been required for underground distribution system. So far, all the efforts for outage-free maintenance for the underground distribution have been limited only to the survey for foreign countries situation and the theoretical provision; thus, It is required to develop the various construction method and the application tools. Differently from the aerial line, the construction of the underground cable is complicated and the insulation distance between conductor and shield should be maintained in loadmaking/breaking operation, though the apparatus connected with cable is a deadfront type. Also since the apparatus is installed above ground, by-pass of faulted area at busy area needs a variety of high technologies. Therefore, in this these, the authors introduce the development status of the loadbreak connectors, connection facilities, outage-free maintenance system for secondary side, a secondary auxiliary bushing and additional tools so that there can be more progress on this field.

The purpose of this study is to gather baseline data on perceived priority of residential choice and housing satisfaction rates among consumers with the aim of using this information for future planning. Self-administered questionnaires were provided to 196 studio-type multi-family housing dwellers in the City of Gwangju from 2009 Apri 5th to 29th. The collected data was used to conduct comparative and descriptive statistical analysis: factor analysis, t-test, one-way ANOVA, correlation analysis. The main findings obtained are as follows: Firstly, in relation to perceived priority of residential choice, dwellers identified seven factors as important. Secondly, in terms of housing satisfaction about a unit room, the respondents identified five factors as important. This study confirmed that there existed passive correlation between priority of residential choice and housing satisfaction among residents in studio-type multi-family housings in Gwangju. It is very necessary to project a studio-type multi-family housing close to transportation for easy access, avoiding commercial districts. Delicate interior and design will attract more female residents as well as fully-equipped parking lots for people who drive to their workplace. According to research on a degree of housing satisfaction, all respondents expressed dissatisfaction with "noise". Therefore, in dealing with construction plans of studio apartment units, from now on, sound proofing facilities are required to reduce the acoustic invasion of privacy, especially, for units with more than two people. In order to satisfy all the demand of residents in studio apartment units, we have to pursue systematic and succeeding research about a studio-type multi-family housing well-fitted for the actual circumstances of local area and suitable for longer stay. To sum up, more research and development will be required for high-class studio-type multiplex housing for sale in dealing with households with financial stability such as two-paycheck couples, so-called DINK, or a professional single person, in the future.

Mushroom cultivation in Korea was launched in the early 1960's. At that time Korean government started a program for increasing cultivation of button mushroom (Agaricus bisporus) and oak mushroom (Lentinula edodes) to export agricultural products and to increase farm income. National research institutes under Rural Development Administration, Korea Forest Service, etc. play a leading role in mushroom industry as follows : Development and spread of genetically superior commercial strains, good spawns, and cultivation techniques. Training and field advice to lead farmers for mass production of high quality mushrooms. Political support of facilities and establishments for mushroom cultivation. Several mushrooms including oak mushroom, button mushroom, oyster mushroom, winter mushroom, Ganoderma, P. eryngii, etc. have been popularized for their cultivation techniques and produced in large quantities in the farm. According to a recent statistics, mushrooms have been grown by about 20,000 farm households, in Korea and the gross production of fresh mushrooms is estimated about 170,000 M/T. The gross production of oyster mushroom is the highest followed by winter mushroom, oak mushroom and button mushroom. The gross amount of mushroom production stands over 700 billion won. Thus, mushroom industry goes to the most important cash crop to be produced yearly.
