In general, when scrap is dissolved in an electric arc furnace, the amount of electric furnace steel dust (EAFD) generated is about 1.5% of the scrap charge amount, and the electric furnace steel dust collected by the bag filter is charged into the Rotary Kiln or Rotary Hearth Furnace (RHF), and the zinc component is recovered as crude zinc oxide, at which time a clinker of Fe-Base is generated. In this research, first, for the efficient resource conversion of electric furnace steel dust, a reduction and roasting experiment was conducted and the reaction kinetics was examined. As a result of the experiment, it was observed that the reduction and roasting reaction was actively conducted in the range of 1100~1150°C, and melting occurred in the range of 1250°C. In the past, this clinker was widely used as a roadbed material for road construction and an Fe-Source for cement production, but in recent years, it has been mainly reclaimed due to strengthening environmental standards. However, landfill treatment is by no means a desirable treatment method due to environmental pollution caused by leachate, expensive landfill costs, and waste of Fe resources. Therefore, in order to more actively recycle the Fe component in the clinker, first of all the clinker was pulverized into an optimal particle size, and anthracite and binder (starch) were added to the magnetic material obtained by specific gravity and magnetic separation for briquet. As a experimental results, it was possible to efficiently separate clinker as Fe component and other slag component by specific gravity and magnetic force. As a results of loading and dissolving the manufactured briquet clinker in an electric arc furnace, it was observed that the unit of power and production yield were clearly improved and the carbon addition effect in molten metal was also somewhat.

Recently, many manufacturing companies try to reform the resources, especially human resources because of fitting the changing environment. That is the reason why knowledge management has very much attention in many companies, recent days. The operating factors of knowledge management are knowledge management process, human resources and information technology. The operating level of these factors will affect the process performance, human resource performance and information technology performance. This means that the higher level of operating process in knowledge management will enhance the higher process performance. The same is in case of human resources and information technology. If process performance is higher, business performance will be higher. The results were as we expected, but not in the case of information technology. The revised model was suggested. Human resource performance affected process performance, information technology performance and business performance. It will be helpful for the success implementation of knowledge management in Korean manufacturing companies.

권동일,김강형,김진관,이성훈,윤재홍 國立 昌原大學校 産業技術硏究所 1994 産技硏論文集 Vol.8 No.-

0.1V강의 표면경도를 향상시키기 위해서 Boronizing처리를 실시하여 Hv=1500∼2000의 높은 경도값을 나타내는 붕화물층을 얻었다. 붕화물층의 두께와 처리시간과의 사이에는 방물선관계를 나타내었으며 붕화물층 생성 겉보기 활성화에너지는 94kJ/mol이다. 또한 900˚C, 3시간 침붕처리했을 때가 가장 높은 경도분포값을 나타내었으며 그 이상 장시간 처리하면 오히려 경도가 감소하는 경향을 나타낸다. 그리고 침붕층은 20% HCl, 20% H₂SO₄용액에서는 뛰어난 내식성을 가지나, 20% HNO₃용액에 대해서는 상대적으로 내식성이 떨어졌다. 그리고 내고온산화성은 대기중 800˚C까지는 침붕처리한 시편이 우수했으나 900˚C부터는 오히려 감소했다. To improve the surface hardness of the 0.1V steel, by Boronizing Treatment, We got boride layer showing high hardness, Hv=1500∼2000. A parabola relationship was appeared between boride layer thickness and treatment time, and apparent activation energy to form the boride layer 94kJ/mol. Moreover, We obtained the most high hardness distribution value when had the boronizing treatment for 3 hours at 900˚C. On the contrary, If we did boronizing treatment above 3 hours, the hardness appeared decreasing tendency. The boride layer had a good corrosion resistance at a solution of 20% HCl and 20% H₂SO₄, but correlatively the corrosion resistance of the boride layer was declined at a solution of 20% HNO₃. And the boronized specimen had a good high temperature oxidation resistance until 800˚C in the atmosphere but the high temperature oxidation resistance go down above 900˚C.

대화적 세계관의 인식론적 토대와 그 교육학적 의미

윤재홍 연세대학교 교육연구소 2000 연세 교육연구 Vol.13 No.1

이 논문에서는 최근에 중요한 철학적 주제 중의 하나인 '포스트모던'의 주제와 이성에 대한 비판을 타자, 비이성, 다양성에 대한 관심과 관련하여 논의하였다. 이성의 한계, 주체의 타자 의존성 등에서 한계에 대한 자각을 생각하고, 타자에 대한 의존과 다양성의 공존을 이끌어내었다. 공존을 위해서는 공존의 윤리와 관계성이 문제되고 여기에서는 그것을 대화적 모델로 모색해 보았다. 대화적 모델, 관계성에 대한 감수성에 바탕한 교육이 포스트모던이 이야기하는 비이성으로서 인간 이해의 확장, 타자의 다양성에 대한 이해의 획득이 가져다준 교육학적 의미로 파악된다. 그 안에서 교사, 학생, 교육내용의 변화를 함께 생각하였다.

The history of a yacht began with a sail attached to a vessel, and such yachting is the game competing for a speed by operating a yacht only though wind force, and a sports in which yachters challenge the limitations of human abilities against rough nature, and vie for human mentality and physical strength. However, due to the awareness that yachting is a luxury sports yet, it fails to get established as general public’s sport for all. Thanks to the recent increase in income and expansion of leisure time, the public concern for yachting is ever increasing through yearning for marine sports as a new sport, and as a means of diversification strategy for Olympic medals led by the government; further, with the increase in commercial value, such as mariner business related to a yacht, the concern for yachting is getting higher not only among the government, companies and yachters but also among the general public. Accordingly, it’s necessary to provide the opportunity for people to enjoy marine sports and expand the base of yachting population through revitalization of yachting and promotion of yacht industry at such a level. However, it’s difficult for the public to contact sailing yacht due to log-distance movement, expensive equipment and lots of required time, etc. Moreover, it’s necessary to obtain the Boat Operator’ License in order to run a sailing yacht according to the Water-related Leisure Activities Safety Act. Accordingly, this study is intending to propose the education & training needed for Boat Operator’s License test consequent on a scenario through a simulator that makes it possible to do basic operation of sailing yacht, and to do operation skills improvement training, and Smart sailing yacht operation license test evaluation system available in time of sailing yacht operation license test in a virtual simulation and on the actual sea. 요트는 배에 세일(Sail)이 부착되면서 그 역사가 시작되었으며, 이러한 요트는 돛을 달고 바람의 힘만으로 배를 몰아 빠르기를 겨루는 경기로 거친 자연에 맞서 인가의 한계에 도전하고 첨단 기술의 집합체인 요트를 이용하여 인간의 지력과 체력을 경쟁하는 스포츠이다. 하지만 우리나라는 아직 고급스포츠라는 인식 때문에 일반 국민의 생활체육으로는 아직 정착되지 못하고 있다. 최근 소득 증가와 여가 시간의 확대로 새로운 스포츠로서 해양스포츠에 대한 동경과 정부의 올림픽 메달 다변화 전력의 수단으로서 관심이 증가하고 있으며, 요트와 관련된 마리나 사업 등 상업적 가치 증가 등으로 정부, 기업체, 요트인 뿐만 아니라 일반국민에게 까지 관심이 높아지고 있다. 이러한 차원에서 요트의 활성화와 요트 산업의 육성을 통해 국민들이 해양스포츠를 즐길 수 있는 기회를 제공과 요트 인구의 저변확대가 필요하다. 하지만 세일링 요트는 원거리 이동, 고가 장비, 많은 시간 요구 등으로 일반인들이 접하기에는 어려움이 있다. 또한, 세일링 요트를 조종하기 위해서는 수상레저안전법에 의한 조종면허가 필요하다. 따라서 본 연구에서는 세일링 요트에 대한 기본적인 조작 및 조종 숙련도 향상 훈련이 가능한 시뮬레이터를 통해 시나리오에 따른 세일링 요트 조종면허 시험에 필요한 교육 훈련과 가상 시뮬레이션 및 실제 해상에서 세일링 요트 조종면허 시험시 사용 가능한 스마트 세일링 요트 조종면허시험 평가 시스템을 제안하고자 한다.

Recently, many manufacturing companies had increased interests in supply chain integration activities between customers and suppliers and their performances. The reasons are increasing costs in manufacturing, faster life cycle of products and lack of scared resources. The purpose of this study is to search the literature about the supply chain integration activities among manufacturers, suppliers and customers. First, supply chain integration was composed of four ; logistics integration, supplier integration, purchasing integration, and information integration. Second, we try to verify the relationship between supply chain integration strategy, supply chain integration performance, and manufacturing performance. Third, we proposed the conceptual framework of supply chain integration and performance in manufacturing. This proposed model will be helpful for achieving competitive advantage and will be analyzed empirically in the near future.
