The ideology of space development can be classified into three types: national security, scientific inquiry, and commercialism. Korea and Japan have influenced the space development innovation system by different proportions. In the rhetoric analysis of Kim Young Sam, Kim Dae Jung, Roh Moo Hyun, and President Lee Myung Bak, the periods when Korea's space development began in earnest, the pragmatism (commercialism) of strengthening industrial competitiveness through space development has been consistently emphasized. But it also maintains national security and scientific inquiry as ancillary.

The purpose of this study is to find out the leisure activity for middle-aged from 45-65 living in the house. The survey had been conducted in 135 respondents with Questionnaire during September 25th to October 7th, 2006. Frequency, Cluster Analysis and Cross tabulation were obtained from the data using SPSS program. The Questionnaire consists of leisure activity and leisure location based on 3 properties of leisure. The results of this study are as follows. First, frequency the respondents is differed by demographic characteristics. Those who have higher level of education, subjective economic power and are younger were more active. Second, the leisure activity in the house is higher in passive on 1st, intellectual and emotional on 2nd, mass media and social activity on 3rd property. Respondents regard home as not a active space but a relax space. Third, the most preferred location in the house for leisure is living-room. Next, master-room and dinning-kichen are. Because of women who spend time more than men in living. Therefore, designing living space for elderly is considered various leisure type of residents.

The purpose of this study was to investigate spatial characteristics and using behavior of activity room in skilled nursing facilities for the elderly and to provide basic guidelines about its space planning. The activity rooms in the most of the research facilities were arranged by usage modification of unnecessary spaces after the foundation of the facility, and were used not only for the program service but for the staff lounge. It decreased space speciality and resulted in limited area of the space and crowded furniture arrangement. The design guidelines for activity room were as follows. First, the space plan of activity room is based on the use of once to twice per week and for 30 minutes per use, and is mainly for the human knowledge and art programs that are appropriate for small group. Second, the activity room of the facility with less than 3 stories needs to be in the same floor as elderly individual room, but should be independent and easy to be controlled by the staff. On the other hand, in more than 4 stories facility, it is better to be in the different floor as the elderly living area such as administrational area close to the lounge and garden. Third, at least $5.9m^{2}$ per user for the area of the activity room is recommended including the elderly, staff, furniture, equipments and restroom. Fourth, the furniture of activity room includes the shelves, big table with enough knee space, wheel, and stopper, and stackable chairs. Toilets and water closet are needed for the emergency, and the windows to the corridor and curtain door should be avoided for soundproof and easy access of wheelchair users.

This study examines diagrams of space organization and classroom activity zoning through Korean Childcare Accreditation Criteria, and compares space diagrams with childcare facilities in Daejeon, and looks at similarities and differences between them. Space diagram from accreditation criteria show the classroom, adjoining toilets, napping areas, and community areas for playing, reading, cooking, teaching and holding materials. Classroom zone diagrams show 8 activity zones for entering, washing and toilet, making art, playing, reading, studying science, resting, playing role and wooden block. Six case studies in Daejeon, Korea were surveyed and classified into big, medium and small size facilities by the number of children. The space organization of case studies are similar to the diagrams, except that outdoor playground and indoor playrooms were not large enough at the small and medium size facilities. Classroom activity zoning was very similar to the conceptions, excluding the playarea from classroom, integrating the rest areas for reading, subdividing art into music and art, science, and into math and science, roleplay into roleplay and wooden block. In conclusion childcare centers in Daejeon are designed to the concept diagram of the accreditation criteria, with some flexibility, exclusion, integration, and subdivision of space and activity zones. It has been requested as to make each criteria fit to the facility sizes-big, medium and small.

A vector space based augmented structural kinematic (VSASK) feature descriptor is proposed for human activity recognition. An action descriptor is built by integrating the structural and kinematic properties of the actor using vector space based augmented matrix representation. Using the local or global information separately may not provide sufficient action characteristics. The proposed action descriptor combines both the local (pose) and global (position and velocity) features using augmented matrix schema and thereby increases the robustness of the descriptor. A multiclass support vector machine (SVM) is used to learn each action descriptor for the corresponding activity classification and understanding. The performance of the proposed descriptor is experimentally analyzed using the Weizmann and KTH datasets. The average recognition rate for the Weizmann and KTH datasets is 100% and 99.89%, respectively. The computational time for the proposed descriptor learning is 0.003 seconds, which is an improvement of approximately 1.4% over the existing methods.

This paper describes a new data-handing, based on a Spatial Human Interface as human indicator, to the Spatial-Knowledge-Tags (SKT) in the spatial memory the Spatial Human Interface (SHI) is a new system that enables us to facilitate human activity in a working environment. The SHI stores human activity data as knowledge and activity history of human into the Spatial Memory in a working environment as three-dimensional space where one acts, and loads them with the Spatial-Knowledge-Tags(SKT) by supporting the enhancement of human activity. To realize this, the purpose of SHI is to construct new relationship among human and distributed networks computers and sensors that is based on intuitive and simultaneous interactions. In this paper, the specified functions of SKT and the realization method of SKT are explained. The utility of SKT is demonstrated in designing a robot motion control.

We have investigated the solar activity variation with period shorter than 1000 days, through Fourier transformation of solar cycle 21 and 22 data. And real time predictions of the flare maximum intensity have been made by multilinear regression method to allow the use of multivariate vectors of sunspot groups or active region characteristics. In addition, we have examined the evolution of magnetic field and current density in active regions at times before and after flare occurrence, to check short term variability of solar activity. According to our results of calculation, solar activity changes with periods of 27.1, 28.0, 52.1, 156.3, 333.3 days for solar cycle 21 and of 26.5, 27.1, 28.9, 54.1, 154, 176.7, 384.6 days for solar cycle 22. Periodic components of about 27, 28, 53, 155 days are found simultaneously at all of two solar cycles. Finally, from our intensive analysis of solar activity data for three different terms of $1977\~1982,\; 1975\~1998,\;and\;1978\~1982$, we find out that our predictions coincide with observations at hit rate of $76\%,\;63\%$, 59 respectively.

Stellar magnetic activity is important for formulating the evolution of the star. To represent the stellar magnetic activity, the S index is defined using the Ca II H+K flux measure from the Mount Wilson Observatory. Mg II lines are generated in a manner similar to the formation of Ca II lines, which are more sensitive to weak chromospheric activity. Mg II flux data are available from the International Ultraviolet Explorer (IUE). Thus, the main purpose of this study was to analyze the magnetic activity of stars. We used 343 high-resolution IUE spectra of 14 main-sequence G stars to obtain the Mg II continuum surface flux and Mg II line-core flux around 2,800 Å. We calculated S index using the IUE spectra and compared it with the conventional Mount Wilson S index. We found a color (B - V ) dependent association between the S index and the Mg II emission line-core flux. Furthermore, we attempted to obtain the magnetic activity cycles of these stars based on the new S index. Unfortunately, this was not successful because the IUE observation interval of approximately 17 years is too short to estimate the magnetic activity cycles of G-type stars, whose cycles may be longer than the 11 year mean activity cycle of the sun.
