  • There are several treatises about architectural characteristics of Hyangkyo. But those treatises usually treat with the types of site plans or structural characteristics without the historic background. So there needs the approaching methods with the historic background to study about the architecture of Hyangky. This study aims at the sample research about the architecture of Hyangkyo in beginnig period. Kyodong hyangkyo is the first building in hyangkyo. There are some architectural characteristics in this building comparing with the Hyangkyo in ripening period. Such characteristics apper in the site plan of educational spaces and in the floor plans of Myongryundang, Dongjae, Seojae. And there appear some characteristecs in ritual spaces such as the architectural structure of Daesungjun, and the position of stone establishment (Kwansedae, Saengdan) The ritual form of Kyodong hyangkyo has no special characteristics compering with the Hyangkyo in ripening period. These rictual form has kept the general rule of ritura form through the history.

  • This research traces the history of legislative matters regarding the enactment and revision of laws and regulations related to the outdoor landscape in apartment complex. The years before 1976 can be classified as 'a period of darkness' for the landscape in apartment complex due to absence of landscape legislation. From the year of 1977 when the landscape planting and mere necessities were carried out according to the local administration's building standard to the year of 1990 can be classified as 'a period of quickening'. The year of after 1991 when the enactment of the code#32 called "the green space in site" in the "Korea Building Code" and the "Korea Housing Standard & Regulation" was made, and various construction regulations and provisions were revised in order to improve the scantiness of the apartment complex and its environment should be called 'a period of development'.

  • Free-field ground motion during earthquake is significantly affected by the local site conditions and it is essential in the seismic design to perform the accurate site-specific ground response analysis. In this paper, one-dimensional seismic characteristics of waste landfill are studied based on the vertical propagation of horizontal shear waves through the column of soil/waste. Seismic response analysis is peformed for short-period, long-period and artificial earthquake ground motions using a computer program for seismic response analysis of horizontally layered soil deposits. The computed peak ground accelerations are compared with the values calculated according to Korean seismic design guidelines. The analysis result shows that the long-period earthquake causes the largest peak ground acceleration while the artificial earthquake results in the smallest one.

  • The concentrations of organic and elemental carbon were determined using fine particle samples collected from Kosan, Cheju Island during the summer seasons of 1994 and 1995. The daily mean concentrations of organic and elemental carbon for each measurement period were 3.74 and 0.27 $\mu\textrm{g}$/㎥ in 1994, while those of 1995 were 2.36 and 0.10 $\mu\textrm{g}$/㎥, respectively The concentrations of organic carbon were higher than those commonly observed from clean areas around the world, but those of elemental carbon were lower than, or comparable to, other clean areas in the world. The resulting ratios of total carbon to elemental carbon at this site were thus higher than those seen from other metropolitan and non-polluted regions abroad. In addition according to our analysis, the 1994 measurement period can be classified into two periods: enhanced (July 20 and August 1) and reduced levels (August 2 and 9) of the carbonaceous species. The observed difference between two periods may be in part accounted for by the air trajectories representing each period. During the former period, the air masses from the Asian continent and Japan were dominant, while the air masses from the North Pacific Ocean came during the latter period. OC/EC ratios at the site were calculated to predict the possible formation of secondary organic aerosol . Based on our observations, we suggest that the formation of secondary organic aerosol might be an important pathway to the production of organic carbons.

  • Under the influence of globalization, South Korea has seen a sharp rise in interracial families. South Korean society faces various difficulties since it has not prepared for the stable settlement of families. Therefore, it is necessary to initiate marital education for the settlement of multi-cultural families in a healthy and democratic way. This researcher has developed a marital education program for multi-cultural families. To reflect the special characteristics, this work required the investigation of multi-cultural families in Gyeongsangbuk-do. The purpose of this work is to improve conjugal relations among multi-cultural families in a formative period of family relations to help those families to settle down early. The program consisted of four steps and 12 sessions. It featured an increase in application flexibility to an actual site by session, and includes a worksheet applicable to an actual site to understand the absence of communication and cultural differences in multi-cultural families during a formative period of family relations. In so doing, it was designed to easily perform nonverbal education. This work is expected to contribute to an improvement in conjugal relations of multi-cultural families in a formative period of family relations and help those families to settle down in a stable way.

  • The goal of this research is to compare influences for living periods between physical functional satisfaction and psychological emotional satisfaction in a ghetto area. The research site is 'Sujin1 dong' in Sungnam city which is one of the oldest residential areas in the city. Based on the analysis of the urban contexts for the research site, surveys are conducted to gather the data which are treated by several statistical techniques: 'Factor analysis', 'Reliability Analysis', 'Multiple regression analysis'. Through the statistical process, conclusions are drawn as follows. In the ghetto urban area, (1)-The higher the psychological emotional satisfaction, the longer the living period, (2)-The longer the residence period, the lower the physical and functional satisfaction, (3)-The two satisfactions tend to be opposite to each other according to the living period. (4)-The psychological emotional satisfaction is more related with living period than the physical and functional satisfaction is.

  • In order to make reliable earthquake-resistant design of civil engineering structures, one of the most important considerations in a region with high seismicity is to pay attention to the local soil condition of regions. It is aimed in the current study at specifying dynamic soil characteristics of Kirikkale city center conducting the 1-D equivalent linear and non-linear site response analyses. Due to high vulnerability and seismicity of the city center of Kirikkale surrounded by active many faults, such as the North Anatolian Fault (NAF), the city of Kirikkale is classified as highly earthquake-prone city. The first effort to determine critical site response parameter is to perform the seismic hazard analyses of the region through the earthquake record catalogues. The moment magnitude of the city center is obtained as $M_w=7.0$ according to the recorded probability of exceedance of 10% in the last 50 years. Using the data from site tests, the 1-D equivalent linear (EL) and nonlinear site response analyses (NL) are performed with respect to the shear modulus reduction and damping ratio models proposed in literature. The important engineering parameters of the amplification ratio, predominant site period, peak ground acceleration (PGA) and spectral acceleration values are predicted. Except for the periods between the period of T=0.2-1.0 s, the results from the NL are obtained to be similar to the EL results. Lower spectral acceleration values are estimated in the locations of the city where the higher amplification ratio is attained or vice-versa. Construction of high-rise buildings with modal periods higher than T=1.0 s are obtained to be suitable for the city of Kirikkale. The buildings at the city center are recommended to be assessed with street survey rapid structural evaluation methods so as to mitigate seismic damages. The obtained contour maps in this study are estimated to be effective for visually characterizing the city in terms of the considered parameters.
