The aim of this study is how to understand of structural and elemental landscape image in suburban village. Nowadays, it is well known fact that suburban villages are most likely to be invaded by urbanization. Therefore, the research is focused on how the image of suburb has been changed, what patterns have been created in residential area, what are the different outcomes from different distance, and what are the changes in types of buildings, at particular village called Doojeong in Pyeongtaek city. When collecting supplemental information, elders in village have been participated in comparison of traditional and foreign. The village shows significant characteristics of such phenomenon. According to the research, there are three results. First, ironically, the structural patterns of the village is concentric as seen on urban garden, yet they do not have central function. Second, traditional homes are transformed into functional shape. The most popular roof design that takes 65 percent of whole is modernized flat roof shape. Hanok (Korean traditional house) style is disappearing. Third, due to the massive barn buildings and their monochrome, the beauty of community and architectural harmony are buried.

In Korea, only a few wooden pagodas are extant because some wooden pagodas were lost due to artificial environment like war. Fortunately, only Eight Depictions Hall(Palsangjeon) in Beobjusa temple and main hall of Ssang-Bong Sa the main temple are extant. Though main hall of Ssang-Bong Sa the main temple shows old style in construction and outstanding creativity, survey and investigation for the hall have been poor. Accordingly, this study investigated pillar part, bracket structure part, and roof part composing pagoda body section which actively reflects structure and design skill compared to floor or upper part. And for better understanding, in the part that is similar to pagoda body section of main hall or needs examples, wooden pagoda in China or Japan was referred. Through this investigation, it was known that unique skill applied to main hall of Ssang-Bong Sa the main temple is based on plane in one room ${\times}$ one room - Ssang-Bong Sa the main temple has common form of wooden pagoda in appearance.

The Long-Term Biodiversity Research Programme (LTBRP) for Mindanao is envisioned to be a collaborative programme of the Philippines. It will be a programmatic research on biodiversity - its status, threats. and conservation and management. The chosen research site is Mt. Malindang in Misamis Occidental of Mindanao. The BRP will support a set of research projects that will generate knowledge on biological and ecological, socio-economic. cultural and policy aspects of biodiversity conservation. It will also enable researchers to develop and try new methods for research on these aspects, separately or crossing boundaries of academic disciplines. Moreover. the BRP will implement support programmes which will provide the linkages of research activities to development issues and needs in the research site. The support programmes will also draw from the research projects, the knowledge that can be lent or immediately available to policy and programme formulation. The support programmes will comprise: human resource development or capability-building; information, education and communication; database; networking; community organizing: and development action. The BRP will be undertaken by a group of academie and research institutions from the Philippines, in partnership with their respective government entities and local government units in Mindanao. The Biodiversity Research Programme (BRP) will comprise a set of research projects to be undertaken by small research teams in the site. Researchable areas have been identified initially through the National Biodiversity Research Agenda. and later enriched in the Participatory Rural Appraisal (PRA) Analysis workshops by the Mindanao researchers and Philippine resource persons. Results of the PRA are presented in the paper.

Many countries and international organizations have carried out rover missions to explore planetary surfaces. Accordingly, the demand for mechatronics education, which is closely related to building exploratory robots, is also steadily increasing. However, due to the complexity in understanding the background information needed for mechatronics, it is hard for pre-college students to study such process. In this study, we suggest an educational platform for mechatronics using a combined robot kit with a spherical robot and a smartphone application. To provide a visual understanding, the dynamic model of the robot is constructed while analyzing the error between actual driving and a simulation, and the educational algorithm of the game and a feedback method are proposed to improve the learning efficacy by considering the user's level of knowledge of mechatronics. We use this educational spherical robot to develop a curling game platform that can impart engineering education even when students lack significant knowledge.

This study aims to contribute to urban policy for more effective disaster prevention, as abnormal natural disasters are becoming more frequent. Up to now, the urban plan for disaster prevention in Korea merely includes basic principles and necessities of measures as an early stage. Furthermore, there are difficulties to make specific programs because the legal system, technical instruments, and financial supports are not sufficient. Therefore, this study figures out problems in the current plan related to urban prevention after analyzing the legal system and practices. Resulting from case studies in developed countries, the study draws significant implications, as follows: enhancing legally binding force; improving the procedures for the programs; establising technical infrastructure. It first suggests a way for the urban policy for disaster prevention by considering our local features comprehensively. It then defines the roles of central, local governemnts and research institutions, and the procedure for urban disaster prevention planning building on the individual roles. This study concludes that an emphasis should be placed on institutional tools necessary to publish technical guideline and establish the system so that urban planners more easily access to disaster risk information.

Rethinking the Value of Family. This study compares and contrasts positive and negative viewpoints concerning the family. Currently, a resurgence in positive viewpoints has exposed the untruths and myths put forth concerning the family on the part of those with a more pessimistic viewpoint. However, those with negative viewpoints still have not acknowledged that the family is an important part of human lives. In this study, the "equal family" (a family where tasks are split evenly among, say, the mother and father with regard to both vocation and household tasks) is criticized as an alternative to the "unfair family", as the "equal family" structure fails to go beyond the liberalization of family relationships to create a virtuous structure worthy of emulation by the children in the family. This is true in spite of the fact that the "equal family" structure has done much to improve individual freedom in the lives of its members. In conclusion, this study posits a third family structure, the "life family," as a new alternative to the other two models. The "life family" recognizes the family's central role: as a safe haven for raising children and building human esteem through close long-term relationships.

In this paper, the incremental nonlinear dynamic analysis is used to evaluate the seismic performance of steel moment frame structures. To this purpose, three special moment frame structure with 5, 10 and 15 stories are designed according to the Iran's national building code for steel structures and the provisions for design of earthquake resistant buildings (2800 code). Incremental Nonlinear Analysis (IDA) is performed for 15 different ground motions, and responses of the structures are evaluated. For the immediate occupancy and the collapse prevention performance levels, the probability that seismic demand exceeds the seismic capacity of the structures is computed based on FEMA350. Also, fragility curves are plotted for three high-code damage levels using HASUS provisions. Based on the obtained results, it is evident that increase in the height of the frame structures reduces the reliability level. In addition, it is concluded that for the design earthquake the probability of exceeding average collapse prevention level is considerably larger than high and full collapse prevention levels.9.

It has been general view to Josun palace space that the Kyongbok palace, a main palace, is arranged with symmetric geometrical composition principles and, unlikely main palace, sub-palaces such as Changduk, Changkyong and Kyonghee palace are placed in organic structure adapted to natural land form. With that view, there are no common factors to be considered between these palace, main and sub palace, in composting principles of the space. In this study, because of same ideological period, although there is external difference of that palaces, that common ideological principles are projected to these two palaces types through compositing space is assumed. On this hypostasis, this study has been focused on finding the ideological principles projected to these palace space commonly. As result of study, some of them are considered as common principles; Firstly, they are arranged in the text of contents through the way of naming to building, enterence and so on. The second point is ; it is viewed that the Oheung and symmetric arrangement method based on Oheung are used in compositing of palace space. The third is ; through analizing central space of Kyongbok palace, it is analized that oneness composition principles, which are based on the theory of Umyangheong, are projected to different palace space commonly.

A new trinuclear complex $[Ru(TPrPc)(CO)]_2[Ru(pytpy)_2](PF_6)_2$ (TPrPc = 2,7,12,17-tetra-n-propylporphycenato dianion and pytpy = 4'-(4-pyridyl)-2,2':6',2"-terpyridine) has been synthesized and characterized as the first example of a discrete molecular wire containing metalloporohycenes as a building block. The trinuclear complex shows multiple-step redox behavior in 0.1 M n-$Bu_4NPF_6$-dichloromethane. The mononuclear $[Ru(pytpy)_2]^{2+}$ precursor shows emission at 640 nm (deaerated acetone, 298 K) upon illumination at the metal-to-ligand charge transfer (MLCT) band at 495 nm, but the trinuclear molecular wire is found to be non-emissive upon photoexcitation at the central $[Ru(pytpy)_2]^{2+}$ entity, indicating an efficient quenching ability of the axially-linked, ruthenium(II)-porphycene chromophores in an intramolecular fashion.
