The concept of the satellite formation flight is area where it is actively study with expandability and safety compare to existing satellite. For execution of duty with more safety issue, it needs to consider hot topic of space debris for operation of formation flight. In this paper, it suggests heuristic algorithm to have avoidance maneuver for space debris towards operating flight formation. Indeed it covers, using common software, operating simulation to nearest space environment and not only to have goal of avoidance but also minimizing the usage of fuel and finding optimization for maximizing cycle of formation flight. For improvement on convergence speed of existing heuristic algorithm, it substitute to hybrid heuristic algorithm, PSOGSA, and the result of simulation, it represents the satisfaction of minimum range for successful avoidance maneuver and compare to not using avoidance maneuver, it keeps more than three times of formation maintenance performance. From these, it is meaningful results of showing several success goals like simple avoidance collision and fuel usage and decreasing number of times of maintaining formation maneuver.

Building energy consumption takes up almost 25% of the total energy consumption. Therefore, diversified ways, such as improving wall and window insulation, have been considered to reduce building energy consumption. Recently, green roof system has been explored as an effective alternative for dealing with reducing heating and cooling energy, thermal island effect and improving water quality. However, recent studies regarding a green roof system have only focused on building energy reduction without considering the applied usage, location, and story of the green roof system. Therefore, this study pays attention to the heating and cooling energy in relation to the applied usage, location, and story of a green roof system for investigating its impact on energy reduction. The result of simulations show that the reduction in heating energy consumption is higher when applied to Cherwon-gun province which has a continental climate condition, compared to the city of Busan that is distinguished by its warm climate. Cooling energy saving turns out to be higher when the green roof system is applied to Busan in comparison with Cherwon. As for the applied usage or function of the building, residential space acquires the highest heating and cooling energy saving effect rather than commerce, educational or office space because of HVAC's running time based on usage. When it comes to the story of the green roof, both heating and cooling energy saving become the highest when the green roof is applied to single-storied buildings. The reason is that single story building is affected by the ground largely. Generally, the variations of heating energy consumption are larger than the cooling energy consumption. The outcome of the simulations, when a green roof system is applied, indicates that the energy consumption reduction rate is dynamically responding to the applied usage, location, and story. Therefore, these factors should be counted closely for maximizing the reduction of energy consumption through green roof systems.

The paper explores the formation of Makerspace in public libraries, based on a survey on space usage and programs being operated. The respondents targeted librarians in public libraries. The survey is divided into two categories: in space usage section, the questionnaire explores level of openness of the space used; availability of equipment rental services; frequencies of the space rented; cost of management; and the number of people in charge. In program section, the survey asks on types of program being operated; spaces used for the program; age groups of participants, time and budget spent for the programs. The survey resulted in highlighting difficulties in dealing with a lack of equipment, space, and people in charge. The paper therefore raises the need of guidelines for the area, cost, and the equipment needed, based on mid- and long-term consultation with expert groups.

It is possible to explain the design, the meaning, and the use of domestic space by comparing different cultures. The characteristics of Koreans' housing life living in western cultures has already been studied extensively. Because of political reasons, however, the characteristics of Koreans' housing life living in Chinese culture has hardly been studied at all. The purpose of this study was to find out the characteristics of succession and transformation of domestic housing culture. The data was collected by questionnaire methods from fifty Korean households and eleven Chinese households. Individual interviews and actual surveys, including taking pictures were also used for data collection. The results of this study were as follows (1)An analysis of heating system usage behaviors showed the importance of heated floors, known as Ondol, is one of the enduring characteristics of domestic habits. (2)In the sitting style, the traditional sitting on the floor was shown in living room. (3)Regarding room usage behavior, Korean households were centered around the living room in chinese houses. (4)An analysis of space organization preferences with respect to common spaces revealed that Korean households tend to prefer the open plan of common spaces.

Mobile web applications are different from desktop web applications because of their small screen size and small user input devices. Therefore user interface designers have spent their effort and time to re-design the user interface of mobile web applications to meet these differences. In this paper, we introduce five user interface patterns for mobile web applications to reduce their effort and time. Two of them are for utilizing small screen size efficiently, and they are space overloading pattern and data filtering pattern. These patterns enable designers to reduce screen usage. The other three patterns - data suggestion pattern, input reuse pattern, and incremental data input pattern - are for helping users' data input on mobile devices. These three patterns enable users to reduce direct data input. Our work will help user interface designers develop mobile web interface to utilize screen space efficiently and get data with less errors and less efforts from users.

Senior centers in apartment complex have been provided since 1980 according to the Housing Act in Korea. Nowadays these senior centers are model leisure facility for the elderly. However there are no specific guidelines for space composition and usage in a senior center. This study examines the space composition and usage patterns of 16 senior centers in apartment complex, Jangyou New Town. The data were collected by means of an observation, measuring, and interviews. The results are ; 1) A senior center consisted of one living room and two rooms for men and women would be appropriate; A living room is for common activities and two rooms for casual resting of each gender. 2) A kitchen is mainly used for setting the table or making tea. Thus, the living-dining-kitchen type would be appropriate. 3) Many rest rooms are located outside of a senior center and unisex one. The restroom should be separated by gender and located within the senior center. Also, the width of all doors should be more than 80cm and the floor be flat. The grab bars should be installed near the fixtures in a restroom. 4) Design and location of the shoe shelf are not convenient for the elderly to use. It should be designed and arranged for the elderly to use conveniently. Also, space for canes, walkers or wheelchairs should be considered in entrance area.
