      • 공정제어에 의한 Ti-Al계 복합화합물의 제조에 관한 기초 연구

        정연채,이동수,윤대원,이상화 동아대학교 생산기술연구소 2000 生産技術硏究所硏究論文集 Vol.5 No.1

        The Ti-Aluminide intermetallic compounds which used in the tumbler and planetary ball mill were fabricated by MA-SPS. The results are as follows. 1. The Planetary ball mill alloying time was shorter than the tumbler and the mainly produced phase after SPS was Ti_3Al phase. 2. The process which added N_2gas during mechanical alloying(MA) decreased mechanical alloying time and increased the yield ratio of alloying powders. 3. The density of sintered body nearly reached the theory density when SPS sintering temperature was over 1050℃ Therefore Ti-Aluminide intermetallic compounds could be produced.

      • 대형 사무소건물의 열원설비 교체를 위한 최적 냉난방 시스템 제안 연구

        정연욱,이은혜,홍원화 대한건축학회 2003 대한건축학회 학술발표대회 논문집 - 계획계/구조계 Vol.23 No.1

        The old equipments can be a factor of increase in the cost of fuel and electric power, and a loss of energy. So, We have to improve technical problems to save energy and build an efficient system. Therefore, in this study, a process of maintaining and repairing old equipments in big office buildings, we surveyed the plans of diagnosis on the main equipments and the measures against malfunction, and suggested some solutions when considered, altering the equipments of heat sources. In addition to analyze the advantages and disadvantages of those systems, and compare initial investment and annual operational costs according to classification of heat sources, we will provide evaluation data for selecting the most efficient and economic system.

        울스모크(Woolsmok)기법에 의한 면직물에 응용된 질감표현 : 롤테크닉과 세탁기 작업에 의한 비교 Comparison of the Works Using the Rolltechnique and the Washing Machine

        오연옥 한국의류산업학회 2004 한국의류산업학회지 Vol.6 No.2

        The domestic textile industry is currently making an active effort to present high value-added materials that can respond immediately to the wants and needs of consumers sensitive to the of originality of design and emotionally appealing fashion materials. This paper attempted to present the creative development of materials in the contemporary clothing culture in which consumers' needs are individualized and differentiated and the cycle of life in fashion materials is getting shorter. To be specific, the paper presented the texture of peculiar expression to diverse cotton materials using the Woolsmok technique in the processing of felt. The chosen Merino wool was felted to 8 kinds of cotton with different density and structure. The touch, texture, visibility and complex susceptibilities of new materials were presented as different materials of cotton and wool were transformed into one material. In felting cotton fiber through wool, the trans-formation of diverse textures was presented and compared in the method using the washing machine in an attempt to enhance the efficiency of the traditional craft technique and work. This study proposed the possibility of placing the new material made up of cotton and wool beyond the range of functionality of each simple material, activating it as the peculiar material and expanding it to the range of its use as fashion material in the clothing industry. It is expected that this material will become competitive material at home and abroad by being activated as the clothing material of artistry, workability and marketability that can satisfy the tastes of consumers who call for high quality and diversification.

Since that year in original, about twenty factories were established these areas but the number of available factories are only fifteen now. This issue has an aim to find the improvements of management of Saemaul factories. Conclusively classified with various business of above factories to do the improvements of it, there was emerged some fragility as follows in the face of production, employment, distribution, financial construction. 1.

The former is based on the unequality between the goveror and governed, the latter is hasd on the equality between the governor and governed. Because they have different background after the 19c, revolution, the former couldn't outcast the monarch (the king), but the latter could outcast the monarch through the 19c. revolution and the former must have recevied the King's political requirement aquinst the citizens through the constitutinal compromise between them, but latter hadn't the king and needed not receive the Kimg's requirement only could have the lule of law for the citizens' equality. The 20c, political doctrine was welfare state, and every countries in the world were needed it in order to remove the poverty from capitalism and liveralism, especialy Englo-American law system countries were devorded in practiing the liberalism through 19c, so matters of proletarans were serious, they must have had the welfare state systems and rule of law should receive not only leveralism but also wel3838fare systems in it as a technics of practicing the welfare state, they were the administrative law, administrave commission board and administrative tribunal etc. So the contents of constitutionalism between cantinental one and Englo-American one are approched each others.
