Purpose: The purpose of this study was to explore relationship among pain, body image and satisfaction in hand-injured workers. Methods: Using a sample of 96 out-patient workers with hand injuries, pain, body image and satisfaction were measured by VAS and Modified Jung Keum-hee's Tennesee Self Concept Scale. Repeated measured ANOVA and a Bonferroni correction for multiple statistical testing during post hoc analyses were conducted to evaluate relationship among pain, body image and satisfaction in hand-injured workers. Result: Functional satisfaction(r=.46, p<.001) and appearance satisfaction(r=.55, p<.001) significantly increased by treatment satisfaction. Functional satisfaction(r=.35, p=.001) and appearance satisfaction(r=.31, p=.002) increased by body image. But treatment satisfaction(r=-.20, p=.049), functional satisfaction (r=-.34, p=.001) and appearance satisfaction (r=-.39, p<.001) significantly decreased by pain. Conclusion: Poor pain management was related to bad body image and treatment satisfaction. Therefore, interventions targeting at pain management are needed for hand-injured workers.

Recently, the structure of simulation environment is important issue in all fields. In case of the training for operating the machines which are costly such as airplanes or spaceships, simulators could be helpful for decreasing the costs and training effects by simulating real situation. When we get the driving license, too many peoples are waiting for their turns because of limited cars and testing spaces in Korea. To solve this problem, we've designed and developed the basic design for the simulators. We suggested the Computer 3D Simulation Model for practice of a drives's license. The concept of this simulator was from a 3D Racing-game which suit for driving exercise. We provide users with handle-controlled simulation setting in order that users feel reality as if they drive really through this simulator. We also use 'force-feedback' system which give handle vibration in case users collide against obstacles or exceed the line since users can absorb the simulation program and feel the sense for the real. This paper is the study about modeling the driving exercise model made use of 'computer 3D simulation', and producing and utilizing the simulator through this modeling.

As the distributed generation becomes more reliable and economically feasible, it is expected that a higher application of the distributed generation units would be interconnected to the existing grids. This new generation technology is linked to a large number of factors like economics and performance, safety and reliability, market regulations, environmental issues, or grid connection constrains. KEPOD (Korea Electric Power Corporation) is performing the project to develope the Distributed Micro Gas Turbine (MGT) technologies by using Swine BID-ENERGY. This paper describes the plans and strategies for the renewable energy of MGT on actual grid-connection under Korean situations. KEPOD also, has a research plan on bio-gas pretreatment system applicable to our domestic swine renewable resources and is performing concept design of pilot plant to test grid operation. In addition, this testing will be conducted in order to respond to a wide variety of needs for application and economic evaluation in the field of On-site generation.

The purpose of this study is to understand the concept of transformative learning and the meaning and process of learning. Transformative learning explains that learning takes place in three aspects. First, Instrumental learning takes place in the process of acquiring knowledge based on facts, such as hypothesis testing. Secondly, Communicative learning recognizes the meaning of other people's thoughts or social norms, cultures and values through language. Thirdly, emancipatory learning makes through critical self-reflection by understanding oneself on the basis of psychological and cultural assumptions. The implications of outplacement convergence education, is that main purpose of outplacement education is to build theory and shift the perspective to learning conversion in general operation practice. The content of the outplacement convergence education is that it should shift from instrumental learning to communicative and emancipatory learning.

Artificial Intelligence is generally concerned with tasks whose execution appears to involve some intelligence if done by humans, and knowledge-based system ( in other word, expert system) is the research about the specific domain. This concept also can be applied to interior design field. So the purpose of this study is in reconstructing the accomplishment of artificial Intelligence and knowledge engineering, searching basic theories and cased to knowledge engineering , searching basic theories and cases to formulate knowledge -based design system, and testing the posibilities how the design information can be dealt in computer system. Given that recognition , two major problems must be solved before knowledge-based CAD systems could be come practical : Firstly , identification of the interior of designers use .Secondly , representing this knowledge in a computationally effective manner. I had discussed the basic concepts on which to base a knowledge- based design model, knowledge representation schemes, and problem solving, I could find the possibility which the knowledge-based system can be applied to the interior design according to this study. But there are non-deductive, often irrational and now easily computerized design process in interior design. Those are problems which are relevant to the machine learning and the creativity in design. So there should be a lot of research about the machine learning and the creatively in design in order to construct successfully intelligent knowledge-based design system.

It is important to predict the collision behavior of a train consist to improve its crashworthiness. To analyze crash behavior of train, four kinds of methods are mainly used so far. The first is method using multibody dynamics to predict the gross motion of the train set. The second uses 3D FE model to apply the section analysis method in order. The third is used to deduce design specification and evaluate the crashworhiness of a train by using 1D model. The last is to constitute 2D model to check overriding and coupling devices. The train evaluation procedures are so complex that it is difficult to understand or deal with. In this study, VTM for railway train was introduced to simplify the procedures. VTM involves 3D models, 1D models and dynamic components such as suspension and coupling. The method using hybrid concept model makes it possible to do all the things that are mentioned above. To analyze crash behavior tendency of VTM, the model was simulated and the simulation results were discussed.

This study aims to present explicit findings from an internal perspective, namely the interaction patterns of marketing communication between pentahelix elements and testing the expectations of tourists towards tourism activities through a simulation model between variables. This study is divided into two methods of analysis, namely qualitative explorative, where the study aims to invest in communication patterns and patterns of interaction between pentahelix stakeholders in Sitiwinangun Tourism Village, West Java, Indonesia with involve 17 informants who came from pentahelix elements (Government, academics, community, business and media). Second, quantitative method to measure the extent of effectiveness rather than collaboration activities and the role of marketing communication to tourist satisfaction is done by an analytical approach involving 30 tourists through customer satisfaction surveys. The results of this study illustrate that the involvement of each pentahelix element has not been maximized. The pattern of interaction and communication between elements also shows the gap between interests, expectations, and reality. This study provides a real picture that to realize a tourism program that is profitable, holistic, and sustainable requires collaboration that is wrapped with transparent and interactive communication patterns. The marketing communication concept approach combined with collaboration theory between stakeholders can be useful for sustainable tourism.

A digital ultrasonic image construction system was developed for the nondestructive detection of cracks in water distribution pipes. The system consists of PC based ultrasonic testing system and a scanning device. The PC based ultrasonic system has an ultrasonic pulse/receive board for the generation and reception of ultrasonic signals, an analogue to digital conversion board for the digitization of the received ultrasonic signals, and transducers for the ultrasonic sensors. Using this system, the digitized ultrasonic signals were properly constructed in accordance with the position information obtained by scanning device that moves an ultrasonic transducer along the outer surface of pipes. In the construction of the ultrasonic signals, signal processing concepts, such as spatial average and array concept, were considered to enhance the resolution of ultrasonic images of pipe wall. Using the developed system, crack detection experiments were performed in both laboratory and field, which shows promise for crack detection in the water distribution system.

Knowledge creation and management are regarded as critical success factors for an organization's survival in the knowledge era. As a process of knowledge acquisition and sharing, organizational learning mechanisms (OLMs) guide the learning function of organizations represented by its different learning activities. We examined a variety of learning processes that constitute OLMs. In this study, we aimed to capture the process and framework of OLMs and knowledge sharing and acquisition. Factors facilitating OLMs were investigated at three levels: individual, group, and organizational. The concept of an OLM has received some attention in the field of organizational learning, however, the relationship among the factors generating OLMs has not been empirically tested. As part of the ongoing discussion, we attempted a systemic approach for OLMs. OLMs can be represented by factors that are inherent to the organization's system; therefore, prior to empirically testing the OLM generating factor(s), evaluation of its organizational integration is required to determine effective treatment of each factor. Thus, we developed a framework to manage knowledge and proposed a method to numerically evaluate factors influencing the OLMs. Specifically, composite importance (CI) of the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method was applied to explore the interaction effect of these factors based on systemic approach. The augmented matrix thus generated is expected to serve as a stochastic matrix of an absorbing Markov chain.
