Residential space has come to maintain a degree of specialization dependent upon the division of space according to function, while roles and functions have either expanded or ceased to exist corresponding to shifts in social values. However, various human behaviors connected to lifestyle habits and values are in fact becoming obsolete. This research will examine the mental, social, and functional aspects of the relationship between residential work spaces in modern homes and the sarangche as well as the communal space of daily and social life of the Chosun Dynasty to enhance the value and function of traditional residential space. As the boundary between family and work blurs with the home office environment of today, we are experiencing a deterioration of health and seeing problems in securing family domain as well as the prolonging of overwork. While the function of the traditional sarangchae encompassed a wider variety of activities than today's homes, the sarangchae achieved an efficient use of space divisions between rooms according to the particular purpose and situation. Accordingly, a reinterpretation of modern residential work space is needed through its connection to the sarangchae with consideration to the philosophy and values of the life of the noble class and the habits of our traditional lifestyle that have previously taken place within the sarangchae in an exterior space.

The purpose of this study is to think about the educational effect of school space innovation project through user participation, to investigate and analyze the actual situation of user participation school space innovation project of elementary, middle and high schools of Incheon Metropolitan Office of Education, The educational effect was analyzed. After the students and teachers participated in the improvement of the school space, the students' skills were improved. Overall, emotional abilities were most cultivated, and elementary school students were most physically cultivated. The intimacy created by participation and activities and play-oriented projects may have helped to develop students' abilities. In addition, the school became fun after user participation, and there was a positive effect of increasing a sense of apathy and belonging. The expansion of user participation has resulted in not only the satisfaction of space but also the friendship and emotional part of students. As a result of this study, the school space constructed through the user participation process brought about significant educational changes in school life and individual quality of life in the learning activities and school life of teachers and students, the main users of the school space.

The purpose of this study is to understand the architectural space of Donggung(東宮), the Prince's Palace, and Dongjo(東朝), the King's Mother and Queen's living space, in the early Joseon Dynasty. The Royal palace can be divided into three parts, political space for king, living space for king and his family and government office. So first, we should to understand the characteristics of each space in the Royal Palace. Up to now we have looked at the architectural space of Donggung(東宮) and Dongjo(東朝) in Gyeongbokgung(景福宮), one of the Royal Palace, the result of this study is as followings. Donggung which was living space for Prince consisted of Jaseondang(資善堂), Seunwhadang(承華堂) and Kyejodang(繼照堂) in the era of King Sejong Kyejodang was demolished and Seunwhadang was destroyed by fire in King Jungjong era and was not rebuilded. This buildings The buildings consisted of Jeondang, Whudang, main gate, hapmun(閤門) and corridor or fence Donggung and Dongjo was separated wall Dong consisted of many buildings for Queen dowager, Queen and many royal concubines The arrangement of Donggung and Dongjo was assumed like as the Fig2.

In this work, preliminary launch opportunities from NARO Space Center to the Sun-Earth Lagrange point are analyzed. Among five different Sun-Earth Lagrange points, L1 and L2 points are selected as suitable candidates for, respectively, solar and astrophysics missions. With high fidelity dynamics models, the L1 and L2 point targeting problem is formulated regarding the location of NARO Space Center and relevant Target Interface Point (TIP) for each different launch date is derived including launch injection energy per unit mass (C3), Right ascension of the injection orbit Apoapsis Vector (RAV) and Declination of the injection orbit Apoapsis Vector (DAV). Potential launch periods to achieve L1 and L2 transfer trajectory are also investigated regarding coasting characteristics from NARO Space Center. The magnitude of the Lagrange Orbit Insertion (LOI) burn, as well as the Orbit Maintenance (OM) maneuver to maintain more than one year of mission orbit around the Lagrange points, is also derived as an example. Even the current work has been made under many assumptions as there are no specific mission goals currently defined yet, so results from the current work could be a good starting point to extend diversities of future Korean deep-space missions.

A photoelectric dimming control system for a small private office space with a double skin envelope system was analyzed for the purpose of examining optimum control performances under a variety of daylight conditions. Computer simulations were performed for the three different photosensor types positioned at the center of ceiling in the space. They were applied in both a south and north-facing room. Daylight conditions were a fixed horizontal venetian blind on an external envelope and a retractable shading device on an internal envelope under a clear, intermediate and overcast sky at different times of a day and year. Partially-shielded photosensors provided good control performances providing the required electric light output under clear and intermediate sky conditions. Unshielded photosensors failed to provide necessary illuminance levels producing less electric output and fully-shielded photosensors generally provided excessive light output. Reasonable electric lighting energy savings were achieved except under overcast sky conditions where the control system did not contribute to energy savings due to the less daylight through envelopes. The retractable shading device covering 50% of the internal envelope reduced energy savings up to 19.62%, but the workplane illuminance levels were maintained within recommended ranges. The coefficients of determination between workplane illuminance and photosensor illuminance due to daylight ranged from 0.74 to 0.98. Partially-shielded conditions provided best correlations and the north-facing room yielded stronger correlation than the south-facing room.

Aerodynamic analysis for the airfoil, KARI-11-180 having 18% thickness ratio, was performed with CFD techniques. The boundary layer grid was generated by projecting the wall grid normally and fine grid was placed behind the trailing edge to capture the wake accurately. The distance to the far boundary is 100 chords and the flow condition is same as the wind tunnel test condition. Transition SST and DES turbulence models were utilized for accurate prediction of the transiton point. The predicted lift is higher but the drag is predicted lower than the wind tunnel test. 3-dimensional results with airfoil models of which aspect ratio were 2 and 5 were compared with 2-dimensional results.
