  • 현재 ERP와 CRM은 대부분 전통적인 기능적 수행에만 초점이 맞추어져 있다. 그러나 최근의 경영환경은 인터넷(Internet)과 이를 기반으로 하는 전자상거래의 비약적 발전에 기인하여 시장의 변화를 가져왔으며, 이는 대부분 e-비즈니스화 되어 가고 있으며, 이를 추진하면서 제휴기관과의 관계증진, 고객관계의 혁신적 개선은 물론 조직내부의 업무프로세스의 획기적 개선을 통한 경쟁력 강화를 적극적으로 전개하고 있다. CRM(Customer Relationship Management)은 기업이 획득한 고객을 지속적으로 유지하고, 기업에 대한 고객의 가치를 증진시키기 위해 기업과 고객간의 상호 이익적 관계를 형성 유지 강화하려는 기업의 일련의 마케팅과정으로 다양하고도 수많은 고객들의 정보를 기반으로 수행되기 때문에 고객 정보를 파악할 수 있는 시스템 기반을 필요로 하며, 생산과 상품의 전달경로, 마케팅, 그리고 의사결정 등의 경영 카테고리와 연관되어 있다. 한편 ERP는 SCM과 CRM 및 SEM(Strategic Enterprise Management)등으로 기능을 확대해감에 따라 21세기의 ERP는 e-비즈니스의 전략적 도구로 발전해 갈 것이다. 본 논문에서는 이를 위한 중재 도구를 제시함으로써 고객에게 더욱 더 효율적이고 고 부가가치 있는 의미 있는 데이터들의 통계적 기계 학습법을 통해 CRM의 기능들을 효율적으로 분류할 수 있도록 한다. 또한 시스템 특징으로는 기존에 수작업으로 이루어지던 파일의 분류 작업을 기계 학습법을 통한 에이전트가 자동으로 수행함으로써 사용자가 좀 더 효율적으로 작업을 수행 할 수 있도록 한 것이다.

  • 공급사슬관리(SCM)는 공급사슬의 가치를 높이고 변화하는 환경에 더 민첩하게 적응할 수 있는 전략적인 접근방식이다. 공급사슬 파트너 간에 중단 없는 파트너쉽과 가치 창출을 위해서는 정보와 지식의 공유 및 적절한 파트너 선정기준이 적용되어야 한다. 따라서 파트너 선정 기준은 제품의 품질과 신뢰도를 유지하기 위해서 아주 중요하다. 제품의 각 부품은 적절한 공급 파트너를 통해서 공급된다. 파트너를 선정하는 기준은 기술적 능력, 품질, 가격, 지속성 등 여러 요인이 있다. 실제로 파트너 선정기준은 구성부품의 특성에 따라서 변화할 수 있다. 그 부품이 핵심 구성품이면 품질이 가격에 비해서 최고 우선순위가 된다. 표준부품은 낮은 가격이 우선순위를 가진다. 간혹 긴급 주문과 같은 예기치 못한 상황이 발생하면 우선순위가 변하게 된다. 따라서 SCM 파트너 선정 기준은 구성부품의 특성과 상황에 따라서 동적으로 결정 되어진다. 이 연구의 목적은 상황과 부품의 특성에 따라서 공급사슬 파트너쉽을 위한 온톨로지 모델을 제시하고자 하는 것이다. 변수의 불확실성은 퍼지이론을 이용하여 나타내고자 하였다. 부품별 우선순위와 상황변수는 웹 온톨로지 언어(OWL : Web Ontology Language)를 이용하여 모델링 하였다. 부품의 우선순위는 퍼지로직을 이용한 퍼지소속함수로 변환 되어진다. 온톨로지의 추론을 위해서 SWRL(Semantic Web Rule Language)을 이용하였다. 제안된 모델의 구현을 위해서 자동차 구성품인 스타트모터 부품을 대상으로 온톨로지를 구축하고 구성 부품별 우선순위에 따른 공급 파트너를 선정하는 과정을 제시하였다.

  • This paper presents a new sensorless control scheme using simple duty signal feedback technique in DC-DC converters. The proposed sensorless control scheme (DFC) has the characteristics that they show the same as operation performance of current mode control by using duty feedback technique without current sensor as well as present better dynamic response performance than conventional sensorless current mode control (SCM) in case that input source is perturbed by step change or DC input source includes the . harmonics. Also, the proposed control scheme has good noise immunity and simple control circuits since they have one feedback loop, and can be applied to all DC-DC converters. The concept and control principles of the proposed control scheme are explained in detail and the validity of the proposed control scheme is verified through several interesting simulated results.

  • While related with electronic commerce and supply chain management, the concept of ERP is more extended. Even information technology makes it more important to achieve company competence Automobile material industry in which there are the variety of suppliers and materials, has to relate with external information such as supply chain information in order to induct efficient ERP system. This study focuses on the induction policies of ERP system through data sharing within supply chain, and performed both case study and statistical analysis through the interviews to the suppliers of automobile materials. To the better induction of ERP through information sharing of SCM, we have to consider the needs of partner of which information sharing is being done well. This study suggests that organizational change management, business process, information technology are orderly taken into account as the analytical results.

  • The Purpose of this study is to examine logistics characteristics related to electronic commerce and to suggest improvement of logistics Service in electronic commerce. This paper concerns the logistics functions which are essential for completing a commerce process even under the EC environment and provides ways to improve the logistics performance. Electronic commerce have introduced two scenes; dramatic change of the existing distribution surroundings and noticeable achievement of the economic advance and social efficiency. But, in the same scene, electronic commerce can be a threat to business condition, especially logistics management. It suggests that for activation of EC it is necessary to strengthen the strategic alliances, introduce GPS and use the third party logistics positively to prepare for the settlements of traffic problems, support the introduction of integrated logistics service and logistics information system.

  • GCM(Green Chain Management) is being spread by that companies which apply with eco-friendly concept in entire SCM(Supply Chain Management) perspective is being increased for resolving some recent environmental problems. There are reasons that numerous companies focus on GCM. At first various governments began to directly manage components and material contents about various noxious substances. Second, environment problem management in the entire logistics process from procurement of product materials to distribution of product became to be important according to introduction of certification system that evaluate the environmental impact throughout life-cycle of products. Purposes of this paper are 1) to analyze the GCM process whose important is more increasing in the recent logistics environment change, 2) to comprehend places and sources that generate environmental elements like energy consumption and greenhouse gas emissions in elements of logistics function, and 3) to construct integrated GCM system for observing activity of logistics function throughout life-cycle of products.

  • We wanted to classify the food constitutionally. That was used to make the constitutional diet plan. And we checked through the clinical test. So the food was classified constitutionally by Sasang Constitutional Medicine(SCM). Constitutional diet plan was considered to Nutrition and Constitution. The clinical trial(use Taeumin diet plan) had performed during 8 weeks. We checked the Health and Nutrition condition. As the result, the Taeumin diet plan didn't change the health and nutrition condition of each constitution in good health. That could be presumed that constitution diet plan do not harm to healthy person.

  • This study deals with the friction and wear characteristics of C-N coated spur gear. The PSII apparatus was built and a SCM415 test piece and test gear with steel substrate was treated with carbon nitrogen by this apparatus. The composition and structure of the surface layer were analyzed and compared with that of PVD coated TiN layer. It was found that both of friction coefficient of C-N coating and TiN coating decreased with increasing load, however, C-N coating showed relatively lower friction coefficient than that of TiN coating. We was investigated the effect of C-N coating on hardness, friction and wear. The TiN coated gear showed a more serious friction phenomena than that of C-N coated gear. It was considered that coating of TiN, which was conducted at a vacuum chamber at about 500$^{\circ}C$, results in a tempering of base material that causes microstructural change, which in turn resulted in decreasing of hardness. The C-N coated gear and pinion had higher wear resistance that of TiN coated gear and pinion. C-N coating significantly improved the friction and wear resistance of the gear.

  • When WC and group IV elements are added to Ti(C,N)-Ni cermet, microstructures of the cermet is changed. The change effects directly on the property of the material. In this study, the amount of WC and group IV elements of Ti(C,N) cermet tool was investigated. The composition of WC was changed from 5 to 20wt% to determine the effect of WC on the cutting performance of cermet tool. The more WC was added, the longer the tool life of the cermet tool was. The cermet with lwt% ZrC and l4wt% WC showed the best cutting performance among the investigated cermet tools. The cutting performance of cermet cutting tools suggests the possibility in interrupted cutting for reliability test experimentation was performed repeatedly with $Ti(C_{0.7},N_{0.3})- l4WC-1ZrC-20Ni$ cermet tool machining SCM440. The flank wear of cermet cutting tool at given time condition is suitable for Normal distribution and Log normal distribution by Chi squared test.
