Consumer satisfaction and feelings with form play an essential role in determining the success of a product. However, contemporary industrial design processes typically employ designer driven, intuitive methods for generating and evaluating form concepts. This paper describes the implementation process of web based design support system that helps assess customer's feelings or sensibilities of forms created in each stages of design process. The present web based approach provides designers with fast and various feedbacks about their design in each stage by using assessment with object VR and web 3D as well as ordinary 2D images. Practical application for exterior design of electric vehicle was illustrated and the further refinement of the design support system was discussed.

Virtual view synthesis is essential for 3DTV systems, which utilizes the motion parallax cue. In this paper, we propose a multi-step view synthesis algorithm to efficiently reconstruct an arbitrary view from limited number of known views of a 3D scene. We describe an efficient image rectification procedure which guarantees that an interpolation process produce valid views. This rectification method can deal with all possible camera motions. The idea consists of using a polar parameterization of the image around the epipole. Then, to generate intermediate views, we use an efficient dense disparity estimation algorithm considering features of stereo image pairs. Main concepts of the algorithm are based on the region dividing bidirectional pixel matching. The estimated disparities are used to synthesize intermediate view of stereo images. We use computer simulation to show the result of the proposed algorithm.

This paper propose the new concept & design method and implementation of LonWorks network system for telemetry & remote monitoring and control in BAS. In order to apply this open system, the essential components of LonWorks is analyzed and a new concepts of its design method is proposed. In our experiment, LonWorks network system for telemetry & remote monitoring and control of lighting are designed and fabricated. As a result, it is verified that LonWorks is open, interoperable, reliable network system from the experimental results, especially, node development, network configuration & design, secure communication and MMI.

This research work deals with the development of a new Triangular finite element for the linear analysis of plate bending with transverse shear effect. It is developed in perspective to building shell elements. The displacements field of the element has been developed by the use of the strain-based approach and it is based on the assumed independent functions for the various components of strain insofar as it is allowed by the compatibility equations. Its formulation uses also concepts related to the fourth fictitious node, the static condensation and analytic integration. It is based on the assumptions of tick plate.s theory (Reissner-Mindlin theory). The element possesses three essential external degrees of freedom at each of the four nodes and satisfies the exact representation of the rigid body modes of displacements. As a result of this approach, a new bending plate finite element (Pep43) which is competitive, robust and efficient.

Practice evidenced by reliable knowledge is essential for professionals and practical studies. Because nursing is a human science and practical science, theory and knowledge development is an indispensable task to improve nursing. Nursing is a very special paradigm not exactly correlated to Western medicine and Oriental medicine. However, nursing was influenced by on Western medicine at the beginning, and most nursing theories were established western philosophies. Caring is the essence of nursing. To provide qualitative care which satisfies clients, it is required to respect cultures of the clients. Western and Eastern approaches of thinking are coexisting in Korea no, so the needs for developing a nursing model, East-West Nursing, which blends two approaches are increasing. In this paper, concepts of the East-West Nursing, differences between Oriental and Western medicines, and comparison of nursing metaparadigm in prospects from and Western Philosophies were briefly covered to define the East-West Nursing. Strategies and directions to develop the East-West Nursing were also discussed.

Psycho-social-spiritual care should be included with comprehensive nursing care of cancer patient. Because of human being have four dimensions as physical, psychological, social and spiritual dimension and they do interactional relationship with themselves, others and God. So caregivers of cancer patient have to recognize what they have psycho-social-spiritual needs and have to consider how caregivers can combine these in comprehensive nursing care. Cancer patient will be experienced shock, feeling of crisis and fear of death and will be showed denial, anger, bargaining, depression, accept or give-up, hope, spiritual distress and spiritual needs to which help them to do some rituals or interactions according their religion. Loving attitude is essential of cancer patient care especially of psycho-social-spiritual care. Dr. Kim and her some colleques investigated about this and find out 10 concepts(Caring Behaviors) by Graunded Theory Methodology. They are Noticing, Participating, Sharing, Active Listening, Complimenting, Companioning, Comforting, Hoping, Forgiving, Accepting.

The Existing Protect schedulings are mathematical nodes upon which probability control is based. In fact, under the mechatronics environment in the new product design and development, statistical information is very poor or sometimes non-existent. Probabilistic PERT/CPM methods are not always satisfying because those methods suppose that it is possible to apply central- limit theorem and there exists a critical path which is much mart critical than all the other paths. Fuzzy project scheduling is possibility based scheduling. For this reason, the Fuzzy Project Scheduling essential to design, development and control the new product under the mechatranics environment. This paper deals with a modeling on the project scheduling which use fuzzy set theory. Fuzzy concepts in the project scheduling are shown to be very useful and easy to work with in the R & D system.

Risk assessment of a railway system should be periodically conducted managing a large amount of accumulating accident/incident data and scenarios, which generally requires enormous time and efforts. Therefore, special information management system is essential for railway risk assessment, where data needed for decisions on managing the railway safety could be promptly supported. The objective of this study is to develop a railway accident analysis program for risk assessment. The program is application running on the web which links railway accident analysts throughout the railway industry to a central database. Data entered, together with associated code tables. is stored on MS-SQL database. The program uses the concepts of accident, safety events, causes, related factors(vehicle, person, infrastructure, tool/equipment), recommendations to bring together the various elements of railway accidents. The program will be useful in finding hazard conditions, accident scenarios, quantitatively assessing the risk, and providing pertinent risk measures, eventually serving to prevent railway accidents and reduce severities of railway accidents.

Macrophages play an essential role not only in mediating the first line of defense but also in maintaining tissue homeostasis. In response to extrinsic factors derived from a given tissue, macrophages activate different functional programs to produce polarized macrophage populations responsible for inducing inflammation against microbes, removing cellular debris, and tissue repair. However, accumulating evidence has revealed that macrophage polarization is pivotal in the pathophysiology of metabolic syndromes and cancer, as well as in infectious and autoimmune diseases. Recent advances in transcriptomic and metabolomic studies have highlighted the link between metabolic rewiring of macrophages and their functional plasticity. These findings imply that metabolic adaption to their surrounding microenvironment instructs activation of macrophages with functionally distinct phenotypes, which in turn probably leads to the pathogenesis of a wide spectrum of diseases. In this review, we have introduced emerging concepts in immunometabolism with focus on the impact on functional activation of macrophages. Furthermore, we have discussed the implication of macrophage plasticity on the pathogenesis of metabolic syndromes and cancer, and how the disease microenvironment manipulates macrophage metabolism with regard to the pathophysiology.
