This paper investigates housing defects and housing satisfaction of the aged according to the personal characteristics and their housing environment. Personal interview was made on the 280 senior persons living in Jeonbuk area. Research results are following. Low levels were found in education, self privately-owned property, monthly income. Most of them live in a detached house that is outdated and obsolete. The facility defects of housing were the most serious level in case of the female senior citizen who lives alone. Their house aging was old but had the high deviation among households. Main influencing factors on facility defects of housing were perceived economic status and ownership of house, the next was age of the aged. Main influencing factors on the housing satisfaction were perceived economic status. Housing satisfaction was higher, the better economic level of the aged was, male than female, the less the age was, in case of hot-water usage in bathroom, owner of houses, no difference in floor level, larger storage space of kitchen was. According to the empirical results, we propose the supporting policy of hosing safety for the aged in order to reduce the risk and social cost. Especially the rate of population aging, the aged household, and the detached houses are higher in Jeonbuk rural areas than the other area. Housing facility defects of the elder who lives alone and house aging of theirs are serious level. Local government should have supporting system that considers local difference and characteristics of the aged housing.

This study examined the general housing awareness and awareness on house sharing of college students who are present residents as well as potential residents of shared houses. To achieve this purpose, structured questionnaires were used as a survey tool to understand students' awareness on housing and opinions on house sharing including a range of space sharing, preferences on house mates, and demands on services and facilities. The survey was conducted of college students in Busan, and the data were analyzed by the PASW Statistics 18.0 program. The findings of this study are as follows: 1) The housing awareness was categorized into seven factors by factor analysis. The subjects valued 'personality factor' in the housing awareness. 2) Regarding preference of house mate type, participants preferred a person who has similar lifestyle and in the same gender. 3) As for the space sharing, the subjects didn't want to share a bathroom and shower. Also, they preferred medium or large scale dormitory layout type to small sized apartment type. 4) The most positive aspect of house sharing was 'Reduction of rental and maintenance cost'. On the other hand, 'Difference of daily life pattern' was the most negative aspect of house sharing. 5) In case of services and community spaces, they preferred 'delivery storage service' and 'coin-operated laundry facility'.

Recently, many researches on the supply of public rental-housings that utilize modular houses have been conducted for the expanded supply of public rental house and consumer-customized supply. For this reason, a research on recognition and satisfaction of residents who live in modular houses was conducted based on their evaluations on public rental houses utilizing actual modular houses. Consequently planning guidelines that would increase residency satisfaction was drawn. Surveys and interviews of 'The Gongneung Hee-mang Housing' were conducted, and analyses of descriptive statistics, multiple regression analysis and importance-satisfaction analysis were conducted. The post occupancy evaluations inform that to gain extra recognition by promoting advantages of modular houses and engaging in educational activities are needed. Dealing with issues such as external noises and vibrations, proper common facility, interior space plan, taking account of facility plan is also needed. This study would contribute to establish modular house planning, reflecting the residents' practical demands.

Optimal cooling operation algorithm was developed based on a simulation case of a single family house model equipped with renewable energy facility. EnergyPlus simulation results were used as virtual test data. The model contained three energy storage elements: thermal heat capacity of the living room, chilled water storage tank, and battery. Their charging and discharging schedules were optimized so that daily electricity bill became minimal. As an optimization tool, linear programming was considered because it was possible to obtain results in real time. For its adoption, EnergyPlus-based house model had to be linearly approximated. Results of this study revealed that dynamic cooling load of the living room could be approximated by a linear RC model. Scheduling based on the linear programming was then compared to that by a nonlinear optimization algorithm which was made using GenOpt developed by a national lab in USA. They showed quite similar performances. Therefore, linear programming can be a practical solution to optimal operation scheduling if linear dynamic models are tuned to simulate their real equivalents with reasonable accuracy.

In order to reduce greenhouse gas emissions in recent agricultural energy and increase the energy self-sufficiency rate of each farmer, it is extremely important to expand the supply of solar energy using unused space of agricultural facilities, roof. This study surveyed and analyzed the environmental and administrative factors such as problems according to the structure, azimuth and latitude of broiler houses and stability of standard broiler houses required to use broiler house roof based on the poultry houses in Sangju-si. The results can be summarized as follows: 55.6% of the solar energy facilities of according to the classification of arable lands of broiler houses were available, and 31.7% of them were available by classifying according to the azimuth. However, 20.6% of them were available in the survey considering all the arable land and azimuth. In the roof inclination of the broiler houses, from 20 to $25^{\circ}$ was the most common, 30 broiler houses. The broiler houses with the roof inclination more than $20^{\circ}$ accounted for 63% of the total. It was considered that the inclination was generally proper. In the structural safety, only 3 broiler houses that were constructed as a standard broiler house were available. In practice, all but one broiler house was inappropriate to expand the solar energy project using roof. The solar thermal facility weighed $63.6kg/m^2$ in total: the frame and solar thermal collector weighed $27.8kg/m^2$ and $35.8kg/m^2$, respectively. The standard broiler house required to be internally reinforced. This study suggested a plan for internal reinforcement and a feasible plan because there were problems with structural safety when installing solar thermal and photovoltaic systems.

Almost all countries of the world have recently made great efforts to reduce green-house gases to alleviate the global warming threatening human survival, because a huge amount of carbon dioxide as one of the main green-house gases has been emitted from the combustion processes of fossil fuels such as coal and oil. $CO_2$ capture and storage (CCS) technology is a representative method to diminish the green-house gases, and actively investigated by many countries. This study focuses on the design and construction of a high pressure $CO_2$ injection facility to store it to underground, which is the first $CO_2$ injection in Korea following the steps of the $CO_2$ capture from large $CO_2$ emission sources and transportation to the sea. Injection tests of $CO_2$ on the platform on the sea were carried out in Yeongil Bay of Pohang city in the early 2017. Thus, we were able to perceive the necessary operating conditions of the injection facility, injection characteristic, and knowhow of the injection facility. The results obtained from the injection test shall be utilized for facility upgrades and scale-ups.
