건설산업은 수요층의 질적 성장에 따른 건축물 설계의 다양화가 이루어져 왔다. 하지만 이러한 시도는 중 장기적으로 발생할 수 있는 하자에 대한 인식이 부족하여 오히려 건축물의 가치가 하락하는 문제를 야기하였다. 때문에 건축물의 특성과 하자에 대한 관계를 명확히 할 필요가 있다. 본 연구는 이러한 개념을 건축물 외부에 적용하여 건축물 입면 요소와 하자에 대한 관계를 정량화하는 기법을 제안하였다. 이는 기존에 정성적, 경험적으로 인지했던 입면 요소와 하자의 관계를 정량적으로 제시하여 명확한 관계를 파악할 수 있는 특징이 있다. 본 연구는 이를 픽셀화기법이라 지칭하였으며, 이는 건축물의 입면을 단위구획으로 구분하여 단위구획의 특성에 따른 코드를 부여함으로써 데이터화하는 기법이다. 본 연구에서 제안한 픽셀화기법을 통해 건축물 입면 요소와 하자에 대한 관계를 정량화하고, 이에 대한 능동적 대처 방안의 기틀을 구축하는데 일조하고자 한다.

This study intends to prepare a system that can be used, by applying digital technique, in analyzing complexity of architectural forms that have been visualized by the correlation based on the distribution chart made in accordance with profile lines. The profile lines are derived from the edge analysis of the architectural forms, simplified based on the visual theory. For the purpose, this study was conducted in the following ways: First, problems of the existing models for the elevation analysis were examined along with formal analysis based on visual recognition to consider the profile lines derived from the forms. Secondly, in elevation analysis, profile lines were derived by digital method to measure them qualitatively. To verify the objectivity of the measured data value, a survey was conducted based on the adjective cataloging method, and the correlation of the survey result and analyzed data was analyzed to verify the validity of the derived data. Thirdly, supplementation for the problems deducted from experiments and the possibility to use it in designing were suggested. Digital method has many advantages over the conventional analyzing system in deriving precise data value by excluding subjectivity. It also allows various analytical methods in analyzing numerous data repeatedly. Diversified models and methods of analysis considering numerous factors arising in the process of designing remain assignments to research in future.

In the last couple of decades industrialization and technological development has not only increase in the scale of electrical facilities and it has become more and more complicated and diversified. Furthermore, fires in the electrical transformers, like those that have knocked out power in the country in the past years, are likely to become more common as utility systems begin to show their age. The importance of preventing electrical accidents can never be overemphasized and for this reason, supply of on-line diagnosis system combining information and communication technology(ICT) for the customer's electrical facilities has been increasing recently. The major advantage of on-line diagnosis system is that the device's potential problems could be detected early before a serious deterioration or breakdown occurs. In this paper, We estimated the benefit from the investment in the right of present value of sales, success rate of commercialization regarding R&D investment for development and commercialization of on-line diagnosis technology targeting customer electrical facilities. As a result, the net value added of 29.7 billion won and the increased profit by roughly 7.52 precent are expected.

Casting are widely used nodays as complicated and diversified forming materials due to its superior castability. However the welding of cast iron has not been accompaniced satisfactory resulting in an microstructure change happened in the heat affected zone (HAZ), especially the graphite are formed and shaped consecutively in the area and it has great impact on the crack occuring and growth together with martensite forming in this area. It case of gray cast iron welding, it is required for pre-heat treatment or specific welding consumables to restrain forming the martensite in the HAZ. In this study, by applying the plasma surface overlaid welding. Fe-Mn-Al steel powder has been used for improvement of anti-crackability in the HAZ and much attention has been paid to establish the overlaid welding method for gray cast iron so that optimum welding conditions may prevent the cracking. With our experiments, we have found that to prevent defects which may occur in the HAZ, the overlaid welding technique for gray cast iron has been developed.

The rapid development of information media in the 21th century has given rise to the acceleration of fashion change and its diversification due to individual lifestyle, the personification and differentiation of consumers. This has got away from the function-centeredness of clothing and awakened people to the important task of hi-tech new materials development and design development. We immediately need to develop the measure to cope quickly and properly with changes in the dwindled fabric market. Consumers; needs are personified and diversified and the cycle of fashion materials become curtailed. From this perspective, this study attempted to manufacture the material for capable of satisfying consumers; psychology and needs with the handicraft based on the multi-item and small-quantity production system. This study attempted to present the possibility of differentiating products and developing diverse materials by applying the Woolsmok technique. It is expected that the development of these materials will not simply stay at the level of handicraft but contribute to the competitive materials of creativity and aesthetics by inducing it to be applicable to the industrial world and activate them as differentiated high-grade clothing materials for consumers at home and abroad.

PURPOSES : Owing to the growth of income and socio-economic levels, demands from road users have diversified. Accordingly, new road policies are being actively sought. The metropolitan city government of Busan has been focused on constructing and expanding roads to accommodate the increasing traffic demand. Given the increase in functional characteristics, we need to re-evaluate the hierarchy and function of roads, and specifically remodel the road planning and operations that fit into their functions. METHODS : First, this study focuses on introducing the minimum condition required to redefine the hierarchy of the roads. Second, the authors propose a new model that identifies the impact level of road hierarchy adopting discriminated analysis technique. RESULTS : Authors suggest that we redefine the hierarchy of roads in the central business distinct in Busan, and specifically the arterial roads in Busan, namely, Joonang-daero and Gaya-ro. These roads need to be reequipped with cross walks, a lower speed limit, and exclusive bus lanes to improve their accessibility. CONCLUSIONS : The authors found that the sub-arterial and collector roads have been subjected to excessive loads, owing to inappropriate functions being assigned to the main arterial road. Moreover, given that through traffic is concentrated on the sub-arterial and collector roads, over-speeding and other safety issues are consequently created.
