        The TOC and Six Sigma are the most attention-getting concepts for managing manufacturing companies. Using the ideas and methods of the TOC, companies can achieve a large reduction of work-in-process and finished good inventories, significant improvement in scheduling performance, and substantial earnings increase. The six sigma approach derives the overall process of selecting the right project based on their potential to improve performance metrics and selecting and training the right people to get the business results. These two concepts have different backgrounds and different viewpoints for production systems. so, if the two concepts integrate each other, the synergy effects to innovate production systems can be expected. The purpose of this paper suggest that integration strategy between Six Sigma and TOC for profit maximization.

        물리탐사와 시추자료에 대해 지구통계학적 복합해석 기술을 적용하여 3차원의 암반등급 해석을 수행하였다. 자료 복합 해석을 위한 다양한 지구통계학적 기술 중에서, 본 연구에서는 물리탐사 자료의 값을 추정하고자 하는 지점의 암반등급의 평균치로 치환하는 국소 변이 평균에 의한 단순 크리깅 기술(Simple Kriging with local varying means)을 사용하였다. 암석의 전기비저항 값은 RMR(Rock Mass Rating)값과 양의 상관관계를 갖는 것으로 알려져 있으나 상관 관계 만에 의한 대응방식은 그 양상이 매우 복잡하고 공간적으로 연관되어 있는 경우가 많아 단순히 적용하기 어려운 경우가 많다. 본 연구에서는 전기비저항과 RMR의 일반적 선형 상관관계 외에 지시자 변환(indicator transform)에 의한 비선형 상관관계를 유도하는 방식을 제안하였다. 또한 본 연구에서는 선형 및 비선형 상관관계에 의해 대응된 비저항 값이 실제 RMR과 비교할 때 나타나는 잔차(residual)에 대해 3차원 지구통계학적 분석을 적용하여 이 결과를 상관관계 결과에 추가함으로써 공간적 특성을 반영하는 RMR 평가를 수행할 수 있었다. 사용된 물리탐사 자료는 전기비저항 및 MT(Magnetotelluric) 탐사 자료이며, 총 10공의 시추자료를 통해 획득한 암반등급 값을 이용하였다. 이와 같은 해석은 조사 대상에 대한 광역적 지질조건을 보다 현실적으로 반영하는 암반등급 분포를 만들어내는 것으로 보인다.

        This study proposes a new approach which combines Data Envelopment Analysis (DEA) and the Analytic Hierarchy Process (AHP) techniques to effectively evaluate Decision Making Units (DMUs). While DEA evaluates a quantitative data set, employs linear programming to obtain input and output weights and ranks the performance of DMUs, AHP evaluates the qualitative data retrieved from expert opinions and other managerial information in specifying weights. The objective of this research is to design a decision support process for managers to incorporate positive aspects of DEA's absolute numerical evaluations and AHP's human preference structure values. It is believed that a pragmatic manager will be more receptive to the results that include subjective opinions incorporated into the evaluation of the efficiency of each DMU efficiency when the AHP and DEA are combined simultaneously. The WPDEA method provides better discrimination than the DEA method by reducing the number of efficient units.

        This paper examines to focus on General Strategy of e-logistics activity for SCM(Supply Chain Management) Build-up, especially the field service logistics integration. And this research analyzes the case study(Business of Strategy Group Unit) Survey involving effective logistics management that leads customer satisfaction, seeking to find out the key elements of competitive policy. Because problems arise from the differences between their goals and structures, which cause each side to feel vulnerable to opportunism or shirking of responsibilities by the other. The goal of a logistics system is to ensure that every family planning client always receives the contraceptives partner wants, and that they are in good condition and have not expired. In order to select, procure, and distribute the right quantities of the right contraceptives, managers of the logistics system must keep informed of the rates of use of each contraceptive and of the quantity of available supplies. As a result, We propose that a firm's e-logistics safe strategy is an important locus innovation and a crucial source of value creation for the firm its suppliers, partners, and customers.

        Project CHILD constitutes a unique threedimensional instructional system that has been subjected to substantial evaluation and revision over the course of fifteen years and which has a proven track record of academic success for children in grades K-5. Project CHILD has continued to evolve and slowly expand across the United States. In the 2003-2004 school year there were over 14,000 students and more than 500 teachers involved. The system is based on an alternative, "retrotechno" theory of the proper role of computers in elementary education. The curriculum focus is on reading, writing, and mathematics, while the methodological focus is on team teaching, multiple instructional modes, and a three-year, continuous progress learning cycle. Effective school transformation is obstructed by three major barriers: school organizational structure, fear of losing control, and inappropriate training and staff development. Project CHILD has developed practical and effective ways to surmount these barriers.

        Schools in developing countries such as China are faced with many challenges when it comes to K- 12 technology integration into classrooms and curricula. The Global Education Model School (GEMS) project aims to help schools overcome these challenges. In this paper we first examine the outcomes of the GEMS program in China, on the basis of which we propose a model for facilitating computer technology integration in K-12 schools China. It is the contribution of this new model to move the emphasis from support of teachers from the international and national levels to teacher collaboration at the school and regional levels. Through the use of technology, communities of teachers can be established, providing an enhanced and more sustainable change management process. The ultimate goal of such an improved change management strategy is to help expand technology integration in China's K-12 classrooms.

        일반적으로 운동방정식을 풀기 위해 많이 이용되는 선형근사모델은 계산이 용이한 반면에 큰 변형상태에서는 그 오차가 커지는 단점이 있다. 따라서 엄밀한 구조물의 응답해석을 위해서는 물성과 기하에 대한 비선형성을 고려해야 한다. 또한, 강과 같이 연성이 큰 재료는 소성 변형을 일으키면서 소산되는 에너지의 대부분이 열로 변하게 되며, 이 열은 열역학 제1 법칙과 2 법칙에 따라 다른 부분으로 전달된다. 이렇게 전달된 열은 온도를 상승시켜 재료의 강도를 약화시키는 역할을 하며, 이것이 다시 구조물의 응답에 영향을 미친다. 본 논문에서는 지진 등의 큰 하중을 받거나 화재로 인한 열 하중을 받는 강구조물의 비선형 대 변형 현상을 적절히 해석할 수 있는 열-탄소성 물성모델을 제안하고 3차원 유한요소해석을 수행하려다.

        Recently, spatial data integration for geoscientific application has been regarded as an important task of various geoscientific applications of GIS. Although much research has been reported in the literature, quantitative assessment of the spatial interrelationship between input data layers and an integrated layer has not been considered fully and is in the development stage. Regarding this matter, we propose here, methodologies that account for the spatial interrelationship and spatial patterns in the spatial integration task, namely a multi-buffer zone analysis and a statistical analysis based on a contingency table. The main part of our work, the multi-buffer zone analysis, was addressed and applied to reveal the spatial pattern around geological source primitives and statistical analysis was performed to extract information for the assessment of an integrated layer. Mineral potential mapping using multi-source geoscience data sets from Ogdong in Korea was applied to illustrate application of this methodology.

        일반적으로 토목구조물에서 계측된 가속도 신호의 대부분은 적분이 매우 힘들다. 그 이유는 토목구조에서 계측된 가속도 신호는 일반적으로 비정상신호이며 또한 비가우시안 노이즈와 저주파 노이즈를 포함하고 있어, 저주파 성분이 증폭되는 적분과정에서 수치적 불안정성이 발생할 수 있기 때문이다. 따라서, 본 논문에서는 비정상 신호처리에 탁월한 웨이블릿 변환의 개념을 비가우시안 노이즈와 저주파 노이즈에 대해 확장한 수정된 웨이블릿 변환을 이용한 가속도 기록의 이중 적분방법을 제시하였다. 또한, 예제해석을 통해 제시된 방법이 비정상 신호의 노이즈 및 비가우시안 노이즈와 저주파 노이즈를 제거에 우수한 성능을 보이고 있음을 보였다.

        Systems are often operated by not integration but blocking, i.e., non-standardization. The system blocking is mainly caused by non-standardization or incompatibility. The integrated system is effective, but researches for quantification of effectiveness from integrating system are few. System blocking causes additional cost which is almost intangible and potential. In this paper we proposed a model to quantify the effectiveness of system integration. To verify the validity of proposed model, we applied the model for Korean information and communication industry and forecasted the cost of integration for South and North Korean telecommunication industry in the way of three scenarios.

        The purpose of this review article were to suggest ways for practitioners to determine the presence of sensory integrative dysfunction and something about its characteristics in the absence of the Sensory Integration and Praxis Tests (SIPT) and to suggest to need the use of a top-down assessment approach in the sensory integration approach. The review constructed in two major ways: sensory modulation disorders and disorders of praxis in sensory integration dysfunctions. The methods of test for sensory modulation disorders included a interview, take a sensory history in all sensory system and informal or/and formal observation of children in general and specific environment. Tests for sensory modulation were Sensory Profile (Dunn, 1999), Touch Inventory for Elementary School Children (TIE) and Evaluation of Sensory Processing etc.. The methods of test for disorders for praxis included direct clinical observation, performance of tasks, interview, sensory history, sequencing and balance in occupational performance. The test tools were Bruininks Oseretsky Test of Motor Proficiency (BOTMP), Motor Assessment Battery for Children (MABC), DeGangi-Berk Test of Sensory Integration, Clinical Observation of Motor and Postural Skills (COMPS), Clinical Test of Sensory Interaction with Balance (CTSIB) and Clinical Observations of Neuromotor Performance etc.. This article reviewed assessments of sensory modulation disorders and disorders of praxis within the context of a top-down approach to evaluation. It also presented formal and informal assessments and proposed a mean of assessing sensory integration in the absence of the SIPT.
