As the demand for automation (or autonmation) or clean workplace has grown, the interest in the knowledge and skill regarding safety is rising in manager duty. Moreover, the importance of severity rate of injury has increased due to the enlargement of industry scale, even safety management area has developed. Thus, it is important that production managers, the core of the line process, realize the safety in their production line, even if a safety manager acts as a staff. However, in the duty oriented National Competency Standard (NCS), the education about the safety duty of production management part is insufficient. According to NCS, it is calculated production managers receive only 6.7% of whole safety education regarding the duty related the safety management for production manager in mechanical industry. However, the ability in safety is more demanded from production managers as the concept of "production and safety" turns into the concept of "production with safety". And then in this paper, we will compare and analyze the safety management duty in Korean NCS and the safety management duty in State Leaders Connecting Learning to Work in US manufacturing industry, in terms of the duty of the production manage in mechanical industry (05). And, we will develop the safety duty education system for production manager, by classifying the safety education in domestic mechanical industry into knowledge education, skill education, and attitude education with using AHP(Analytic Hierarchy Process).

국내 대도시의 도심은 인구, 상업, 교통 등의 집중도가 높으므로 공동구 도입에 따른 기대효과가 높고 생애주기비용을 고려한 경제적 타당성을 충분히 확보하고 있다. 더욱이 지하철, 복합환승센터 등과 같은 대규모 지하공간 개발에 포함하여 설치할 경우 초기 건설비용을 획기적으로 줄일 수 있으나 실제 지하개발 계획에 구체적으로 반영되지 못하고 있다. 국내에서 도심지 공동구를 새로이 계획할 경우 기존 Life-Line의 이설비용, 수용 기관별 의견충돌, 건설재원 조달 및 분담 등의 어려움이 예상되며 더욱이 모든 수용기관과 사업시행자로 구성된 공동구 협의회에서 합의를 도출해야만 사업추진이 가능하기 때문에 경제성 분석과 더불어 타당성 평가 시스템을 통한 합리적 의사결정 과정을 통해서 최적 대안이 제시되어야만 원활한 사업추진이 가능하다. 그러므로 도심지 유형별 특성을 고려해서 평가지표와 의사결정 계층구조를 재구성하고 계층의사분석(AHP) 기법을 적용해서 항목별 중요도를 정량화함으로써 타당성 평가시스템을 이용한 합리적인 설계용량 최적화를 지원할 수 있을 것으로 판단된다.

이차곡선은 고등학교 기하 내용의 중요한 개념의 하나이다. 그러나 교수-학습 상황에서 학생들은 단순히 대수적인 접근과 해석기하적인 접근만 시도하므로 그 본질적인 기하학적 의미를 파악하지 못하며 단순한 기계적인 계산만을 수행하여 문제를 풀어나가려 하기 때문에 여러 가지 오개념(misconception)을 가지게 된다. 이 논문은 효과적인 이차곡선 교수학습 연구의 일부로, 학생들의 오개념을 인지적 관점, 심리학적 관점, 교수학적 관점에서 분석하고 그 원인을 분석하였다. 연구 결과, 학생들의 직접적이고 다양한 작도 경험의 부재가 오개념의 주된 원인이 되었다. 이차곡선에 대한 교수-학습은 기하적인 관점으로 접근 한 후 대수적인 관점으로 연결시켜야 할 필요성과 오개념에 대한 정확한 진단은 효과적인 교수-학습의 기초가 됨을 확인 하였다.

In this study, remodeling projects are perceived as a sustainable urban management policy to boost the value of old apartments and stimulate urban regeneration and development. To evaluate the physical environmental performance of external spaces of remodeled apartments, an evaluation model was developed. After applying it to the target places, the following results were obtained. First, analysis of the external space change index of the target apartments revealed that institutional standards are necessary in line with the building arrangement type, parking lot expansion method, and changes in the building-to-land ratio. Second, the score ratio as to the external space change index performance is as follows: safety (48.30); pleasantness (25.90); convenience (18.90); eco-friendliness (14.90). In other words, "safety" had the biggest score ratio. Third, to boost the external space performance of remodeled apartments, the needs of residents and neighboring environmental plans should be considered from a communality standpoint.

The purpose of this study is to clarify the adaptation of beauty of traditional dress depicted contemporary Korean fashion design. For this purpose, the external form and the internal meaning based on 'the double roots' proposed by W$\ddot{o}$lfflin were analyzed in Korean traditional dress. Documentary studies and objective studies were done with descriptive and content analytic methods. And homospatial process was devised in order to develop the traditional identity in contemporary fashion design. The results were as follows: 1. As the external form, H. O. A silhouette, chogori, ch'ima, paji, and po concerning internal type, kaftan, flat form related to structured type were represented. Traditional color sense were love of white, contrasting as well as analogous color harmony shown often in nature phenomena, and temperate achromatic color harmony. Texture were characterized as rough and coarse expressing vividness, fine and smooth expressing delicateness and tenderness. As the internal meaning, the beauty of purity related to nature, tragedy, and symbolism were represented. 2. Since 1980's. Korean fashion designers frequently applied unstructural kaftan form and H silhouette to Korean fashion design, and sought natural and pliable line in whole dress. Use of white and achromatic color harmony as well as use of linnen were prominent. Designers' aesthetic consciousness was pursuit of the beauty of nature. Representative designers who concentrated on expressing traditional beauty were Lee Shinwoo, Sul Yoonhyung, Jin Taiok and others. 3. A homospatial process could be a method in the creative design which enables to express Korean identity in fashion design, and could suggest ideas of new designs full of Korean identity by superimposed and fused imaginery.

In steel making production line, steel slabs are given a unique identification number. This identification number, Slab management number(SMN), gives information about the use of the slab. Identification of SMN has been done by humans for several years, but this is expensive and not accurate and it has been a heavy burden on the workers. Consequently, to improve efficiency, automatic recognition system is desirable. Generally, a recognition system consists of text localization, text extraction, character segmentation, and character recognition. For exact SMN identification, all the stage of the recognition system must be successful. In particular, the text localization is great important stage and difficult to process. However, because of many text-like patterns in a complex background and high fuzziness between the slab and background, directly extracting text region is difficult to process. If the slab region including SMN can be detected precisely, text localization algorithm will be able to be developed on the more simple method and the processing time of the overall recognition system will be reduced. This paper describes about the slab region localization using SIFT(Scale Invariant Feature Transform) features in the image. First, SIFT algorithm is applied the captured background and slab image, then features of two images are matched by Nearest Neighbor(NN) algorithm. However, correct matching rate can be low when two images are matched. Thus, to remove incorrect match between the features of two images, geometric locations of the matched two feature points are used. Finally, search rectangle method is performed in correct matching features, and then the top boundary and side boundaries of the slab region are determined. For this processes, we can reduce search region for extraction of SMN from the slab image. Most cases, to extract text region, search region is heuristically fixed [1][2]. However, the proposed algorithm is more analytic than other algorithms, because the search region is not fixed and the slab region is searched in the whole image. Experimental results show that the proposed algorithm has a good performance.
