Recently, there have been many changes in the domestic construction industry. OSC (Off-Site Construction) is expected to solve these problems, and it is emerging as a way to inspire innovation in the domestic construction production system. OSC, which has only recently attracted attention again after previous studies have failed, is lacking in research on preception surveys and customized performance measurements compared to overseas. This study investigated the perceptions of construction industry workers on OSC through a survey, and examined differences in perceptions of each subject and the relative importance of performance indicators. In general, the need for introduction and development of OSC was recognized. Also, drivers and obstacles inhibiting more use of OSC were analyzed. The relative importance for performance indicators and differences in perceptions of each subject were identified. Then, this study suggests plans for diffusion and revitalization of OSC, and key performance indicator for OSC based PC structure apartment housing.

The purpose of this study is to employ a method called 'conflict impact assessment' to analyze the progress, background, cause and relevant issues of conflicts related with affordable housing for youth (Happiness Housing Project), a project that has been implemented since last May 2013, thereby identifying the relevant problems and draw out objectives for improvement. The researchers expect that this study will contribute to solving the current issues regarding Happiness Housing, and contribute to improving the quality of the government's policies. For the above purpose, literatures on Happiness Housing produced from August to November 2013 were reviewed, in-depth telephone or face-to-face interviews were conducted with personnel associated with project implementation in the Ministry of Land, Infrastructure and Transportation and LH, etc., and major interested parties including Yangcheon-gu residents. Key issues identified regarding Happiness Housing construction include: the way that the project was implemented, living quality of residents, impact on educational environment, inconsistence with existing plans, relatively high construction cost, insolvency of public corporations, land use fee issue with Korail, need of preliminary feasibility survey, securing sufficient amount for supply and issue of additional designation, likelihood of finishing construction in time and issues related with actual source of demand, etc. Through analysis of conflict development and positions of interested parties, the main causes of the conflicts were identified as follows: lack of deliberation on pledges during election, lack of viability review on pledges, lack of conflict management plans, one-way implementation without consent of interested parties, project plans established with no regard to local circumstances, frequent project revision, underwehlming level of conflict management. In order to address issues above, the following measures need to be taken: selecting election pledges based on actual effectiveness, thorough assessment on pledges by relevant departments, gradual implementation based on consideration of the actual circumstances, participation of key interested parties, consistent policy and adopting conflict management techniques that reflect the reality.

This study derived the unit of industrial water usage reflecting the latest industry trends. Available for establishing plans such as the master plan for water supply system and analyzed changes in the basic unit by a comparison with the current basic unit values. This study analyzed 4,038 samples with a sampling error of less than 1.5 % at the 95 % confidence level after removing outliers according to a log-normal distribution. As a result, the unit of industrial water usage per site area in the whole manufacturing industry was 7.11 m3/1,000m2/d. The ten industrial categories (C10, C13, C20, C21, C22, C25, C27, C30, C32, C33) showed a similar unit value compared to before, and the four industrials categories (C11, C17, C22, C31) showed a more unit value than before. With regard to the nine industrial categories (C14, C15, C16, C18, C19, C24, C26, C28, C29), the unit value decreased. Cases that companies examined before were the same as the companies examined in this study were analyzed. The result that the changes in the unit industrial water usage were reasonable was obtained. However, in some industrial categories (C17, C14, C24, C29), the unit value was changed by a small number of companies with large-scale water use or unit value of sampling had a large deviation. It was considered necessary to survey them periodically. The unit of industrial water usage derived by the survey in this study reflects the current industrial trends in 2016. Water use in manufacturing companies has continuously changed by the development of manufacturing technologies and simplification of manufacturing processes. In order to deal with this, it is considered necessary to survey the usage of industrial water periodically from a long-term perspective.

In Japan, apartment housing occupies a great proportion of residence due to high population density like Korea. Although Korea and Japan are similar in big proportions of apartment housing, and apartment housing management systems and utilization behaviors, there are considerable differences. This paper examined Japanese public facilities and the status of public facility management and utilization, which differ from those in Korea. In order to analyze the status of public facilities from a perspective of management companies, a preliminary survey was conducted targeting apartment management companies in the top 100 and a field study on public facilities was conducted targeting chief directors and managers of individual housing facilities to look into public facility utilization methods, problems with public facility management, demands of residents, and utilization situations. Also, the present state of facility utilization and utilization promotion plans were investigated, based on the drawings of facilities collected. As the result, results were found in three respects; 'elements, related to building plans', 'elements, related to utilization promotion', and 'elements, related to facility remodeling, including changes of uses'. In relation to the use of public facilities in the future, a more active communication between managers and users would be needed for planning. Also, there would be a need to provide public facilities for visitors when there are events for both occupants and visitors in order to promote the use of facilities and management companies would have to share information of excellent facility models.

The objective of this paper is to investigate problems associated with the storehouse affiliated with rural housing for the elderly engaged in farming activities, and to suggest improvements with the examples of storehouse floor plans. The elderly in rural area still engage in farming even though they are suffering from aging problems. Therefore, the planning of storehouse which has relevance to agriculture is very important. The methods employed were a field survey and interviews with residents. 12 houses belonging to elderly people (60's and over) were selected by the convenient sampling in Cheonan, Chungcheongnam-do. The results are as follows. First, at least more than 3 storehouses have to be planned to store the goods separatedly according to their kinds and characteristics. Second, storehouses should be placed near or directly connected with the main house to support the accessibility of the elderly. Third, the open space has to be planned in front of the storehouse to park a truck for loading goods directly. Fourth, the storage equipments such as shelves should be planned inside of the storehouse for the space efficiency and user convenience. Fifth, the width of the door should be wide enough to carry agricultural products and goods. It is recommended to use double hinged doors or double pocket doors. Besides, the thresholds of the doors should be removed and, rather than using direct lighting system, it is better to use indirect lightings and task lightings together to minimize glare and to provide enough illumination.

Coastal dunes have many environmental and ecological socio-economic importances; various human activities, however, have impaired their structures and functions over the years. In 2016, environmental survey on coastal sand dune was carried out to report the present status and update the coastal sand dune list in 2001. This research analyzed the survey data in terms of geomorphological and socio-economic aspects. A list of the 189 coastal sand dune and information was updated by province. A 36.5% reduction in coastal sand dune area have been identified for using agricultural land, development area since the approximately 1940-50s. Development area in coastal sand dune covered small area as 5%, the use intensity was relatively hard. Furthermore, the difference by province also showed. Approximately 80% of the development area was concentrated in 20% of total sand dune several sand dune. It is generally accepted that coastal sand dunes were exposed high development pressure. However the result means that the general brief dose not apply for all sand dune. Therefore, characteristics of each sand dune should be analyzed and concerned the diverse management plans.
