The Program from modern architecture is an indispensable condition which must put in all buildings today and it is a relationship setting of a various functions. According to changing society consequently, a complicated form and program in modem appear again. Through this background from, we intend to observe the meaning which the program is having in the construction in this manuscript. Sejima is the architecture who try to use variously special formation of the program. Specially, we are planning to research the quality which his program is haying form Sejima's architecture and how it is reflected ill this construction. Resultantly, each program which appears from Sejima's architecture makes a gap space and irregular arrangement. The characters of the space which is put each through the gap don't have a deceptive plan each other and they are compounded. Also, each character to have their territories is intersected and putting out of the various features in the program coat. First, form of the maze plane, Intersecting each territory. Second, forming the territory as fitting their act oneself in the space where can be existing. Third, having more interest in the event that happens inside than existence problem of thing.

The inverse kinematics problem of a reclaimer which excavates and transports raw materials in a raw yard is investigated. Because of the geometric feature of the equipment in which scooping buckets are attached around the rotating disk, kinematic redundancy occurs in determining joint variable. Link coordinates are introduced following the Denavit-Hartenbery representation. For a given excavation point the forward kinematics yields 3 equations, however the number of involved joint variables in the equations is four. It is shown that the rotating disk at the end of the boom provides an extra passive degree of freedom. Two approaches are investigated in obtaining inverse kinematics solutions. The first method pre-assigns the height of excavation point which can be determined through path planning. A closed form solution is obtained for the first approach. The second method exploits the orthogonality between the normal vector at the excavation point and the z axis of the end-effector coordinate system. The geometry near the reclaiming point has been approximated as a plane, and the plane equation has been obtained by the least square method considering 8 adjacent points near the point. A closed form solution is not found for the second approach, however a linear approximate solution is provided.

Purpose: This study was performed to identify workers' Job stress status and to analyse the influencing factors. Method: Data were collected from 456 workers with Korean Occupational Stress Questionnaire Short Form(KOSQ SF) and analysed using descriptive statistics, t-test, ANOVA. Results: Total job stress status of men was slightly lower than Korean workers' standard. In case of women, the score of total job stress was lower than Korean workers' standard. The most significant influencing factors to stressors were insufficient sleeping time and self cognitive bad health condition. Among seven domains of job stressors, job demand was affected by 8 characteristics. Conclusion: This study indicated that workers' job stress level were various by their characteristics except workplace size. The development of stress management programs by types of industry is required. On the base of the model program, planning of customized program for every company or employee is required. High job demand, insufficient job control, insufficient sleeping time, bad health condition are the key factors of workers' job stress in this study. The change of workers' health behavior with supportive environment is essential to stress management program. More researches for adding physical environment domain to KOSQ SF are expected.

In a state where ancient buildings was left a lot in the case of Korea, many parts do not remain the documentation, and there is a Kiwarisho lot in Japan, however, the present methods and tree split does not exist in the Korea. However, it is impossible to make a perfect building without splitting exact member when making a building. Thus will not be revealed simply by presumption that there is a similar way to wood comparatively far in Korea. Without a comparison of building dimensions and Korea calculation dimensions Kiwarisho In the first study about the proportionality of Korea, I do not know until now, other studies of the following documents which house a high approximation ratio and member size of Korea consider reason to have is impossible. View compared with respect to the axis of the building in the early stages of research first. In the case of Japan and Korea to form a tree frames in basic form that form the building, the shaft portion is easy to understand and easy compared in common is at most the shaft portion.

In the late 1950s, departing from their unquestioning following of Soviet architecture, North Koreans attempted to discover the specificities of traditional Korean architecture and apply them to their contemporary monuments. This paper examines the ways in which North Korean architects developed their unique version of Socialist realism in the making of Pyongyang Grand Theater. The traditional elements in harmony with North Korea's political ideology-an early form of Juche ideology-and modern building technologies were to be viewed as contemporary elements, and not as a simple revival of the past. This study applies Socialist realism's compositional principle "national in form and socialist in content" to Pyongyang Grand Theater and examines specifically what "socialist content" and "national form" were and how the two were combined in the construction of Pyongyang Grand Theater. By situating the building in the context of localization of Socialist realism which is universal art principle of the communist world, this study contributes to the deeper and wider understanding of North Korea's Modern Joseon Architecture.

In the process of complex shopping mall development, all the steps (business planning step, pre-sale & completion step, management & operations step) head towards a consistent ultimate goal in an overall business perspective. In this study, we analyze using a structural equation model if an appropriate relations between each of the steps are formed to achieve the ultimate goal. In this study, we find a positive relationship between business planning step and pre-sale & completion step, and also find that for success pre-sale & completion, a faithful business plan is necessary. But we find no statistically significant relationship under significant level 0.05 among business planning step and management & operations step and the level of success, pre-sale & completion step and management & operations step and the level of success, management & operations step and the level of success. This suggests that each of the steps does not form a close relationship to achieve the consistent goal in the complex shopping mall development and each one is doing a short-sighted work for its own profit.

Urban planning is the task to explore measures for bringing order to the change in urban space of future predicted in relation to the size and purpose of the land and a variety of facilities in cities in order to present the environment that can promote the qualitative improvement of activities of residents, ensure orderly urban space of future, and create appropriate urban environment which meets the desire of citizens by anticipating the urban development on the basis of overall activities such as politics, economics, culture, etc, so that the improvement in urban life can be accomplished ultimately. Therefore, this study attempted to examine current conditions information necessary for establishing policies pursuant to the national land development plan and regional development, as well as respond to the needs of urban residents who need the improvement of settlement environment including various amenities for the convenience of life, by shifting away form the macroscopic and one-size-fits top-down approach of development so far and aiming a balanced development of national land in quest for welfare society and by utilizing the urban index as the basic prior task necessary for seeking the shift ind the direction of policies and setting the direction for policies on the basis of the top-down development approach which suits the anticipation and hope of local residents as the subject of development, considering the growing interest in the shift in the policies for regional development in this era of localization. Techniques for urban planning need to be applied, such as the prior planning and the following development, along with the support at the policy level for achieving the improvement in the related sector, in order to induce continuos urban deelopment based on the establishment of healthy and sound settlement environment, and furthermore, the efforts must be drven forward to improve the urban settlement environment while the urban planning and policies are established.

u-City projects are different with the existing urban development projects progress via convergence with IT technology. Therefore, it inheres many risk factors more than the existing development projects as including more complexity and variety. The risk management system to systematically manage those risks which get identified and quantified is required. Especially, the planning phase that is appeared the various forms has a large effect on the success of the business. However, the management of risk factors remains in the passive form. So the problems on u-City project in the planning phase and risk factors of existing development business were analyzed for the continuous growth and the successful performance of u-City project, and those risk factors was identified and quantified by using statistical technique. In the results of it, the core risk factors were obtained through which way and the basis for the effective risk management in u-City business is provided.

This paper presents a method about amorphous obstacles avoidance for local path planning in the two-dimensional sensor environment. In particular, the proposed method is extended from some of the recent studies about a point obstacle avoidance. In the paper, repulsive forces of two types are proposed in order that the robot avoids from the amorphous obstacle with various size and form. A judgment of curvatures in the proposed method simplifies the recognition of obstacles to make the path-planning efficient. In addition, the line of sight(LOS) and the range of recognition are considered in the environment. By simulation results, the proposed method for amorphous obstacle avoidance shows better performance than the related existing method and we confirmed advantages of proposed method.
