The objective of this paper is to propose a conceptual framework of a BIM based collaboration supporting System, called Construction Project Life Cycle Management (CPLM). The framework of CPLM is proposed by reflecting the characteristics of the AEC industry such as deliverly methods, process, fragmentation, etc.. And it is a system intended to help project participants make better decisions and to facilitate coordination between various stakeholders in a project by providing virtual collaboration environment.

The mechanism of knowledge production in the basic science has been changed throughout the development process in Korea. During the 1970s, the focus resides in the support of individual scientists while it concentrated on the support of research organization, centered on center of excellence from the 1980s. The change in the sup-porting mechanism to basic science result in the transformation of knowledge production system in the university and impact on the behavior of individual scientists. This paper focuses on the co-evolution process between newly adopted supporting program for basic science and the knowledge production system via the case study of representative program of center of excellence supporting program in Korea.

The home network, contributing to improve the quality of life in dwelling, has expanded its installation and use in past years, but the elderly care system supporting self-reliance is not fully prepared. Although the aging society in Korea is progressing rapidly, inducting and spreading home network system is still required supporting of 'Aging in Place' for the elderly. This research is based the survey of spatial characteristics of housing of the elderly. Also, the research studied the technical level and policy of home network in domestic and abroad and analyze the professional view of experts in the home network field, as a result, suggested methods of building and activating the home network system.

In robot system, the robot manipulation needs the information of task and objects to be handled in possessing a variaty of positions and orientations. In the current industrial robot system, determining position and orientation of objects under industrial environments is one of major problems. In order to pick up an object, the roblt needs the information about the position and orientation of object, and between objects and gripper. When sensing is accomplished by pinhole model camera, the mathematical relationship between object points and their images is expressed in terms of perspective, i.e., central projection. In this paper, a new approach to determine the information of the supporting points related to position and orientation of the object using the robot vision system is developed and testified in experimental setup. The result will be useful for the industrial, agricultural, and autonomous robot.

This study presents the methods to improve the urban farming in Korea by analysing the current circumstances of urban farming in Korea. Specifically, the legal system in association with urban farming, current status of the act on the urban farming, the present situation of the Korean urban farming, and the comprehensive plans for urban farming have been analysed in order to grasp the present situations and seek for solutions. Based on these, the research provides effective supporting methods for sustainable urban farming in Korea. As a result, the essentials to improved urban farming can be summarized with two factors; securing more space for urban farming and improving the supporting system for the urban farmers. Enthusiastic attitudes of local governments, security of budget, and cooperation with the citizens are vital to expand the urban farming in addition to the institutional and systematic urban farming improving methods mentioned above.

This paper presents a parametric study and an optimal design of the ER-SFD supporting a rigid rotor system. An attempt is made to obtain the optimal design of an ER-SFD for a two degree-of-freedom rotor model. Such a simple model is used in order to get a better insight into the physics of the problem. A maximum whirl amplitude, supply pressure and voltage are considered, and a maximum whirl amplitude is minimized over a range of speeds and presented f3r some values of unbalance mass. The results presented in this paper provide important design information necessary to reduce a whirl amplitude of an ER-SFD.

After determining the type and string condition of conductor of 765kV transmission lines, we studied the mechanical strength system of insulator strings to support conductors and insulate conductors from towers. In this paper, for the insulator strings which will be used in 765kV transmission lines, we're going to optimally determine the mechanical strength system and supporting method in the consideration of the reliability, economics and the survey data of T/L routes, and also suggest the calculation method to stipulate for the application limits of suspension and strain insulator strings according to the loadspan and height difference of tower.

The goal of this paper is to minimize the weight of the T-structure supporting steering system in reducing the vibration level on steering wheel which could be amplified by the resonance. Presently, requirements for reducing noise, vibration and harshness (NVH) in automotive area are more stringent than ever. One of them is the vibration of steering system which occurs sometimes at high speeds or when the engine is idling. Besides, the reduction of weight is also one of requirements for improvement of vehicle performance. This paper used the micro genetic algorithm as an optimization method to satisfy above two requirements. The whole T-structure assembly including steering column was used for frequency analysis.

The objective of this study is to investigate the commercializations and difficulties on the farm-food. For the activation of the farm-food, it is necessary to totally review the support of the government and prepare the supporting system like manual on the commercialization of farm-food that is helpful to the small farmers. It is also necessary to support small farms strategies customized for increase the sales and satisfaction on farm-food and build-up the promotion related to the green tour and/or farm experience. The results and finding of this study can be used to build-up the supporting system that reflects the rapid change of market and customer's preference. They can also be used to design rational policies that is helpful to the farm-food producers.

An expert system, to assist dam managers for five dams along the Saikawa River, has been developed with a primary objective of achieving swift and accurate reservoir operation decision-makings during floods. The expert system is capable of supporting on decision-makings upon establishment of flood management procedure and release/storage planning. Furthermore, an attempt was made to improve reservoir inflow prediction models for better supporting capability. As a result, accuracy on prediction of inflow up to 7 hours ahead was improved, which is important for flood management of the five dams, using neural network. The neural network inflow prediction models were developed for each types of floods caused by frontal rainfalls, snowmelt and typhoons, after extracting relevant meteorological factors for each.
