The increasing dynamic and distributed nature of a business and manufacturing environment makes it hard to collaborate between design and manufacturing parties. The seamless collaboration necessitates a manufacturing quote service (MQS) that delivers manufacturing quotes timely for designer's requests. After envisioning a SOA-inherited collaboration framework, the paper details MQS' functionalities, and syntax and semantics of collaboration messages (i.e., RFQ and manufacturing quote). The MQS is implemented as a Web Service so as to be accessible by designers. For each RFQ, the MQS adaptively generates a responding manufacturing quote by using the DPM library and real-time shop status information. The paper also presents an evolution process that shows the whole process of RQF generation from given product design data. The proposed framework enabled partners to exchange engineering data rapidly and adaptively during the dynamic collaboration, and also increased the benefits of distributed and global production.

Under the environment of various network and multimedia, various theories are studied to make utilize digital story telling authoring. In the era of digital convergence and ubiquitous information, they want to send information with additional emotional information which is preferred constructive sending method. Digital storytelling refers to a unified technology for narrative structure with the picture and act. If engraft with particular research field, It will make interactive or linear story structure. These structures have problems that they are mismanaging on the result and they are not integrated systemization in each society. Because those are designing storytelling without development process and they are focusing on web distribution. This thesis is design using the object-oriented methodology of component-based design methodology, This thesis create digital storytelling and design metadata for contents management. In the requirement phase, subject and predicate part are extracted from the narrative structure of the story and restructure an organization. We explain by giving specific examples "kongjwi and patjwi" story as a case study.

In this paper, we propose an energy-efficient proactive data dissemination protocol with relatively low delay to cope well with highly mobile sink environments in sensor networks. In order for a dissemination tree to continuously pursue a dynamic sink, we exploit two novel algorithms: forward sink advertisement and distributed fast recovery. In our protocol, the tree is shared with the other slave sinks so that we call it Dynamic Shared Tree (DST) protocol. DST can conserve considerable amount of energy despite maintaining robust connection from all sources to sinks, since tree maintenance of DST is accomplished by just distributed local exchanges. In addition, since the DST is a kindof sink-oriented tree, each source on the DST disseminates data with lower delay along the tree and it also facilitates in-network processing. Through simulations, it is shown that the presented DST is considerably energy-efficient, robust protocol with low delay compared to Directed Diffusion, TTDD, and SEAD, in highly mobile sink environment.

In The Lighting design is important to acknowledge appearance space. Development of artificial light makes a extension to life space in the Modern life. With the rapid development of efficient light sources, have lighting design acquired the tools that allow artificial lighting to be produced with adequate illuminance levels. However, by the task of defining the objectives and methods behind discipline, of deciding on the criteria by which the artificial lighting that is now provide many available data to be anpaied. The main concern is which illuminace levels and types of lighting will ensure optimum visual performance, high productive and safety at design which are affordable. This study is support to standard design process with material reflection rate, installing the lighting fixture, task illuminance level and automatic arithmetic calculation during the lighting design. Lighting Design database can check and support other final lighting level. A quantitative light that is primarily oriented toward providing a recommended illuminance level, the criterion of develop a concept that goes beyond the requirements that would ensure productivity and safety to meet the needs of the architecture and interior space. illuminance level is compose to space task and space code according to KS A 3011. To be able to design the visual effect of an environment the central reference quantity has to provided the Database.

Now days subway represents a gateway of the city and a center of transportation. It belongs basic facilities to connect the town and suburbs and has strongly regarded as a means of development of city. but It's time that the subway should be changed to reach the needs which give visitors comfortable space and convenient image to use it and it also has a function of transportation because the present generation have turned an information-oriented and specialized society. So we try to put the essential points as like the followings, designing the CANOPY (Busan subway-3rd line). the first, We create an distinctive image with effect to get a regional self-confidence the second, we make new traffic space including potential energy in new millennium ages the third, we need an effort and experiment to overcome contradiction pointing to unity between varieties. To conclude, we want to create CANOPY subway with an individual characters for Busan and aim at a fine view and improved image of subway for Busan, considering the belows.

The collapse pressure of tubes is determined experimentally by Tschoepe and Maison for various materials with different geometries. The results are compared with those obtained by ASME Codes UG-31 and UG-28. A collage pressure is the pressure required for the incipient yielding stress of the tubes with and without ovality. This collapse pressure is compared with the experimental results by Tschoepe and Maison. The present investigation is towards finding the collapse pressure required to bring the entire wall of tubes into a state of plastic flow for the pipes, with ovality and without ovality. This collapse pressure is compared with the collapse pressure obtained through experiments in the present investigation. The experimental results are compared with the pressure obtained by FEM(finite element methods). The FEM results are then compared with results obtained through an approximate plastic analysis of the strain hardening material, SA312-TP304 stainless steel. The structural integrity evaluation is performed for the heat exchanger used in an actual nuclear power plant by using various methods described in this paper. The results obtained by the various analyses and the FEM are discussed. consequently, the paper is oriented towards an actual design purpose of d heat exchanger in an industrial environment, rather than for the purpose of an academic research project investigation.

The HANARO, a 30 MW multi-purpose research reactor in Korea, will be equipped with a neutron guide system, in order to transport cold neutrons from the neutron source to the neutron scattering instruments in the neutron guide hall near the reactor building. The neutron guide system of HANARO consists of the in-pile plug assembly with in-pile guides, the primary shutter with in-shutter guides, the neutron guides in the guide shielding room with dedicated secondary shutters, and the neutron guides connected to the instruments in the neutron guide hall. The functions of the in-pile plug assembly are to shield the reactor environment from a nuclear radiation and to support the neutron guides and maintain them precisely oriented. The primary shutter is a mechanical device to be installed just after the in-pile plug assembly, which stops neutron flux on demand. This paper describes the mechanical design of the in-pile plug assembly and the primary shutter for the neutron guide system at HANARO. The design of the guide shielding assembly for the primary shutter and the neutron guides is also presented.

The demands of nursing home for the dementia are rapidly increasing. However, there are no enough nursing homes and design guidelines for it. This study was intended to examine the needs of the staff for the nursing home design and suggest the design guidelines of the Korean nursing home for the dementia. The subjects were 15 nurses and 18 care givers who worked in D hospital for the elderly with dementia in Busan. Data were collected by the self-administered questionnaire. The findings were as follows; First, the most important design element in nursing home for the dementia which the staff mentioned was 'healing environment' and then 'function' and 'maintenance' Second, the care-givers were more satisfied with their facility design than the nurses. Third, the staff pointed out that 'the relation between individual room and nursing station', namely, short distance between them, and 'enough wandering space' had to be considered at first in design process of nursing home with dementia. Also, the comfort and intimate interior mood, fresh air and sunlight were also pointed out as the important elements in nursing home design for the dementia.

We have lost our true characteristics without being grown and development of our traditional beauty in state of drawing into a whirlpool as the environment of western cultrue. So, to be existed for self-sown capability of our traditional culture, we'll have to keep up with the unique and creative Korean traditional furniture design through the synchloization between 'Traditionalism in our already westernized life' and 'Korean identity in our already westernized life' and 'Korean identity in worldwide culture' based on independent position by correct view of worth, as for the escape from attitude of receive on western culture in recklessnese. Hereupon, first of all, after reviewof fornuclation backround and characteristics in traditional furniture to be established by an ancestor, based on this and extract the conceptual language, it was presented past published works as for the approaching method toward physical form aspect by use of pattern of modern access method. Secondly, it was the symbolic approaching from method based on traditional and cultural context. Gradually, the embodiment of traditional image, in today's features of our furniture loosing the particular cultural identify is very important aspect, and beside above mentioned two methods, it should be investigated as for the diversified approaching study. Thereafter, we'll have to establish the positionof our modern furniture in global wordwide, for seek the beauty being interrelated form past historical communications, under the circumstance of original and future-oriented value.
