  • 본 연구에서는 우리 자동차산업이 직면한 총체적인 위기상황을 극복하기 위한 방 안으로, 자동차 생산방식의 변혁, 인적자원관리의 혁신을 통한 생산성 제고, 독자 기술개발 능력의 조기확보, 효율적인 부품조달체제의 형성 등 산업전반에 걸친 혁신으로, 내적인 경 쟁력을 축적함과 동시에, 지역주의화의 진전에 따른 수출 여건의 악화를 극복하기 위해 선 진권 및 개발도상국으로의 현지화 노력이 적극적으로 추진되지 않으면 안될, 중대한 시점에 와 있다고 진단하면서, 본 연구의 목적을, 생산현장을 중심으로 한 내적 경쟁력 확보로 정 의하고, 그 실현방안으로서, 급변하는 시장환경에 적극 대응하기 위한 생산방식의 도입과, 이를 지원하는 생산정보시스템의 구축 모델을 제시하고자 한다. 첫 번째는, 변화가 급격한 시장환경에 적극 대응하는 생산방식의 도입으로, 철저한 낭비 배제 사상 - 생산현장의 낭비 소요를 배제(개선)하는 것만이 아니라 배제하고 바로 체계를 바꾸어 (개혁) 원래의 상태로 되돌아가지 않도록 하는 -을 기본으로, 정보, 관리, 생산, 제품, 물류 등에 관련된 손실 비 용을 감축시킴으로서 원가를 낮추고, 고객이 요구하는 다양하고, 좋은 품질이 제품을 신속 히 공급할 수 있는 체계를 갖추는 것이다. 이러한 낭비 배제 사상은 생산현장에서 필요한 것을, 필요한 때에, 필요한 만큼 만들고 운반하며 전달하는 관리 개선 등을 의미하며, 이것 을 적은 인원 및 설비로 최대한 빨리 (리드 타임의 단축), 계획대로 수행하도록 하는 것이 동기화 생산방식이다. 따라서, 본 연구에서는 자동차 생산공정 중 주 조립공정의 ALC(Assembly Line Control)에 대응하여, 선행 공정으로서 부품을 공급하는 Job Shop의 동기화 생산방식을 실제 적용한 사례 중심으로 전개하고자 한다. 두 번째의 접근방식은, 동 기화 생산방식에 컴퓨터 통합생산 (CIM, Computer Integrated Manufacturing)의 기술을 구 현, 적용하는 것이다. 즉, 동기화 생산 시스템 (SPS, Syncronized Production Sytem)을 구 축하는 것인데, 이것은 최신의 컴퓨터 기술을 생산현장에 적용함으로써 새로운 생산방식의 혁신에 버금가는 기술혁신이라 할 수 있을 것이다. 따라서, 이러한 접근은 컴퓨터 및 통신 기술의 눈부신 발전을 기초로 가능해진 것인데, 제조업에서의 심각한 고비용, 저효율 문제 를 해결하기 위해 필수적으로 도입해야만 하는 실정이다. 또한 소비자의 다양한 요구로 인 하여 제품의 종류와 사양면에서 심한 변동을 보이는 시장 수요에, 신속한 정보처리로 대응 하는데도 크게 기여하고 있다. 이에 본 연구에서는, 자동차 Job Shop의 동기화 생산방식을 지원하는 동기화 생산시스템의 구축 모델을 제시하고자 한다.

  • Characteristics of interconnect lines considering underlayer geometries of a silicon substrate and crossing metal lines are experimentally analyzed through elaborately devised patterns. In this work, test patterns for transmission lines having several kinds of underlayer geometries were devised, and the signal characteristics and responses are measured by S-parameter and time domain reflection meter (TDR). The patterns were designed and fabricated with a deep-submicron CMOS DRAM technology having 1 Tungsten and 2 Aluminum metals. From the analysis of measured results on the patterns, it is founded that the effects of underlayter line structures on line parameters (especially line capacitance and resistance) and signal distortions occurred from them cannot be negligible. The results provide useful and insightful understanding in the skew balance of package leads and global signal lines such as high-speed clock and data lines.

  • This paper addresses a hybrid multi-focus image fusion scheme using the recent curvelet transform constructions. Hybridization is obtained by combining the MS fusion rule with a novel "copy" method. The proposed scheme use MS rule to fuse the m most significant terms in spectrum of an image at each decomposition level. The scheme is dubbed in this work as m-term fusion in adherence to its use of the MSC (most significant coefficients) in the transform set at any given scale, orientation, and translation. We applied the edge-sensitive objective quality measure proposed by Xydeas and Petrovic to evaluate the method. Experimental results show that the proposed scheme is a potential alternative to the redundant, shift-invariant Dual-Tree Complex Wavelet transforms. In particular, it was confirmed that a 50% m-term fusion produces outputs with no visible quality degradation.

  • This study explores the trends and implications of social welfare qualitative research in Korea. The results are follows. At present, social welfare qualitative research is entering in the quickening period. The characteristics of configuration of social welfare qualitative research in Korea are overwhelming inferiority in post-positivism and heuristics, wide differences between universities in metropolitan area and in local area at the aspect of amounts of qualitative research products, rapid increase in the interests of qualitative research in doctoral candidates, and distinguishment of doctoral candidates as a leader group in qualitative research. The results of critics of qualitative researches are follow: 1) initiative of naturalistic interpretism 2) inclination of methodicism 3) poorness of critical themes 4) propensity in grounded theory. These trends of social welfare qualitative research in Korea, in spite of the limits, have various implications: 1) Trying to critics of social welfare knowledge based on positivism and formation of opposing discourse to positivism 2) diversification in paradigm of inquiry 3) spread of narrative thinking of social welfare phenomenon.

  • In some industries, manufacturing firms' distinctive competences include not only product superiority but also service excellence. For example, in a highly volatile and dynamic market, flexibility and responsiveness are more valued than just the product cost. And sales order processing, in that respect is a very important process. However, previous studies on sale order processing have considered only due-date assignments or dealt with production scheduling to minimize production cost or delivery lead time. Due to recent advances in information technology, a new approach is possible in dealing with sales order processing. For example, RFID(Radio Frequency IDentification) and ubiquitous computing technology adds real time visibility and traceability to supply chain. In this study, we develop a new due-date re-negotiation process for sales order management and propose a new business integration model to support the re-negotiation process based on RFID, ubiquitous computing technology and RosettaNet's PIPs.

  • Thrust vector control system is control device which is mounted exit of the nozzle to generate pitch, yaw and roll directional force by deflecting flow direction of the supersonic jet from the nozzle. By obtaining control force, jetvane which is exposed in jet flow is working thermal and aerodynamic load. Axial thrust loss and side thrust is affected by shock patterns and interactions between jetvanes according to jetvane geometry and turning angle. In this study, we designed 6 types of jetvane to evaluate pitch, yaw and roll characteristics of ietvane in supersonic flow, and perform the cold flow test in range of turning angles of jetvanes between $0^{\cire}$ and $25^{\cire}$ by $5^{\cire}$ respectively. Also, calculation is going side by side to analyse flow interaction. Results show that there is no interactions between jetvanes upto turning angle 20$^{\circ}$, chord and lead length ratio is very important parameter to aerodynamic performance and maximum thrust loss is appeard to 17% of axial thrust in roll directional control.

  • Overhaul and repair service means the sequential processes of disassembly, repair and reassembly for a product which has been used for a long time. Overhaul is required for the companies producing airplanes, ships, trains, military weapons and heavy industrial equipments which are very expensive and have a long life cycle. The most important performance measure of the overhaul repair shop is usually the lead time. Thus, how to design the manufacturing system to meet the delivery date is a major concern in overhaul repair shop. This paper introduces the case study of an overhaul repair shop producing military weapon systems with the 3D simulation tool, $QUEST^{TM}$. At first, the characteristics of overhaul shop and what should be considered for simulation modeling are explained. Then, various simulation scenarios including two types of disassembly systems, one is flow line system and the other is cell system, are discussed with the results of simulation experiments.
