Many companies have integrated their internal processes with the aid of information technology. Now the focus is on interconnecting trading partners. Collaborative commerce (also known as c-Commerce) has a key role. It is not just about making it easier for business to communicate. It is about by breaking down barriers along the entire length of the supply chain. Some c-Commerce links are permanent, others get established when and where they are needed. c-Commerce is helping business in electronic supply chains to improve product delivery while cutting costs, to strengthen relationships and to reduce lead time. In this paper, we propose the concept of collaborative commerce, and design and implement Collaborative Commerce Portal (CCP) system of small and medium enterprise for marketing support. The technical definition of CCP is set of all technical elements can do collaborative commerce between small and medium enterprises with Internet or Internet. The target information of CCP includes usual and unusual information and all other information of companies used as process events. Through this, it enhances efficiency of business processes, core information sharing and marketing activation.

Ultimate objective of industrial hygiene is the prevention of health impairment that may result from exposure to chemicals at workplaces. This implies the definition of permissible levels of exposure, that is, levels that according to the present status of knowledge are estimated to cause no adverse health effects during the lifetime of the workers, and the regular assessment of the possible health risk associated with exposure by comparing the current or the integrated exposure with the permissible exposure limits. Workers in solvent thinner-using occupation environment might be highly exposed to VOCs(volatile organic compounds) because solvent thinner has been used extensively such as painting, spraying, degreasing, coating and so on in Korea. The purpose of this study was to recognize, evaluate and propose the alternative control the VOCs from solvent thinner-using workplace.

Optical communication according to request of technology of communications and optical fiber to be full filed faster communication and pass over transmission capacity limit per unit area, per unit hour appeared, and this optical fiber acts the biggest role to influence performance of optical communication network. Optical fiber(PMF Polarization Maintaining Fiber) is used, and is used by electric field measurement, self-discipline measurement, sensor(Sensor) Department by high definition measure such as thermometry and storehouse component that use because make broad sense status and polarized light information in passageway and union with storehouse integrated circuit etc. that use broad sense interference developing could transmit in state that keep transmitting broad sense plane of polarization is polarized light existence. Also, research is developed by optical fiber for Coherent communication recently.

In this paper, we present a method to define a color similarity between color images using Octree-based quantization and similar color integration. The proposed method defines major colors from each image using Octree-based quantization. Two color palettes to consist of major colors are compared based on Euclidean distance and similar color bins between palettes are matched. Multiple matched color bins are integrated and major colors are adjusted. Color histogram based on the color palette is constructed for each image and the difference between two histograms is computed by the weighted Euclidean distance between the matched color bins in consideration of the frequency of each bin. As an experiment to validate the usefulness, we discriminated the same clothing from CCD camera images based on the proposed color similarity analysis. We retrieved the same clothing images with the success rate of 88 % using only color analysis without texture analysis.

The purposes of this paper are applying the IDEF(Integrated DEFinition), which was selected for standard methodology of CALS(Computer-aided Acquisition and Logistic Support) process modeling, to the acquisition process of the weapon system to activate DEfense CALS of the acquisition and management business of weapon system on Defense Planning and Management System and developing a AS-IS model which is usable and that the analysis of process problems results in. On this paper, We diagrammed the function of the acquisition and management of weapon system by using IDEF0 and presented AS-IS model. This paper focused on the development of AS-IS model which can put to practical use to find the problems of current acquisition and management process of weapon system and the embodiment of national defense CALS system. So more detailed analysis of current system and additional studies about TO-BE model would be the future research area.

A home network system was implemented using IPv6 and SIP. We integrated different kinds of home devices into IPv6 address system, and built control system independent of controller's address and location, using SIP. Also, controllers can download each device centrol messages without any global definition of handling it. We implemented this system by home device emulator, and PDA controller to control home devices.

본 논문은 고해상도의 영상을 처리하는 이동기기 등에 사용되는 SoC(System On a Chip)에 구현이 용이한 효과적인 화질 향상 (잡음감소와 윤곽강조) 을 위한 방법과 구조에 대한 것이다. 최근 이동기기의 발전과 진화에 따라 여러 형태의 이동기기가 개발되고 있는데 그 중 최근 인기를 끌고 있는 포터블 미디어 플레이어 (PMP)나 HD(Hight Definition)급 camcorder 등이 고해상도의 영상을 처리하는 이동기기로 분류될 수 있다. 이러한 이동기기에서 고해상도 영상에 대한 화질 향상을 기존의 복잡한 방법을 사용해 처리한다면 메모리 대역폭이나 하드웨어 크기 등의 증가로 이동기기에서 구현하는데 어려움이 따른다. 이에 본 논문에서는 이러한 이동기기에서의 고해상도의 화질 향상을 입력영상의 종류에 따라 선택적으로 메모리 대역폭 사용 없이 하드웨어 크기를 최소화하여 FPGA (field programmable gate array)나 ASIC (application specific integrated circuit)으로 구현이 용이하도록 하는 방법과 구조에 대해 설명하고 실제 영상을 가지고 실험한 결과로 주관적 화질 향상 효과를 가져 온 것을 확인할 수 있었다.

인터넷을 이용한 기업간 전자상거래를 위해 기업 내부의 업무 흐름을 관리하는 워크플로우에 관한 관심이 높아지고 있다. 워크플로우 엔진을 구동시키기 위해 먼저 고려되어야 하는 것이 기업 내부의 업무 프로세스를 정의하고 정의된 프로세스를 validation할 수 있는 모델링 도구가 필요하다. 이에 본 논문에서는 물류 협업 프로세스를 정의하고 모델링하기 위한 EJB 기반의 Business Process Modeling Tool(BPMT)를 설계 및 구현하다. BPMT는 WPDL을 지원하는 다 기종의 워크플로우 엔진에서도 협력 체제를 구축할 수 있도록 설계되었으며, 프로세스를 수행시키기 위한 Activity, Transition, Process, Organization, Application, RelevantData DataType으로 구성 되는 일련의 업무 흐름을 정의하며, 범용적인 의미의 Process 설계 도구로서 사용자가 편리하게 작업할 수 있도록 Integrated UI를 지 원한다. 또한 기본적인 물류 영역의 업무 프로세스를 라이브러리화하여 제공함으로써 사용자로 하여금 새로운 물류 프로세스 정의를 쉽게 한다.

In Chapter 40, "Information for decision-making", of Agenda 21, it was Slated that, "indicators of sustainable development need to be developed to provide solid bases for decision-making at all levels and to contribute to a self-regulating sustainability of integrated environment and development systems." Sustainable development has been defined as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs", An indicator that measures sustainability should therefore focus on this definition. One of the most widely used frameworks for environmental indicators is the Pressure-State-Response model proposed by the OECD. And we introduced the the Driving force-State-Response framework, the adaptation of Pressure-State-Response model, for UN sustainable development indicators. Therefore, in our country, indicators for sustainable development should be developed by using the DSR framework.
