Nowadays, a lot of enterprise completed the ERP implementation and these ERP-based enterprises consider the construction of WMS or already have done it. However the enterprises which Implemented WMS linked with ERP have many problems In the warehouse management and the reason ran be summarized In two poults First. In the integration point of view, only Interface issue between ERP and WMS was taken into account, therefore it was hard to reflect the phased process change. Second, a large number of WMS functions were tried to implement at the same tune and these attempts caused confusion and Instability which Is Interpreted as a main reason of the WMS failure. This paper presents the phased construction method for the successful implementation or WMS and in the integration point or view, the phased process change appears naturally

In this paper we proposed the format converter design and implementation for real time image processing. This design method is based on realized the large processor-per-pixel array by integrated circuit technology in which this two types of integrated structure is can be classify associative parallel processor and parallel process with DRAM cell. Layout pitch of one-bit-wide logic is identical memory cell pitch to array high density PEs in integrate structure. This format converter design has control path implementation efficiently, and can be utilized the high technology without complicated controller hardware. Sequence of array instruction are generated by host computer before process start, and instructions are saved on unit controller. Host computer is executed the pixel-parallel operation starting at saved instructions after processing start

The broadband wireless access industry, which provides high-tate network connections to stationary sites, has matured to the point at which it now has a standard for second-generation wireless metropolitan area networks. IEEE Standard 802.16, with its WirelessMAN air interface, set the stage for widespread and effective deployments worldwide. This paper presents an implementation of media access control that can be applied to BWA (Broadband Wireless Access) system. Medium access control (MAC) is a key issue in multi-access networks where a common channel is shared by many users. The designed MAC prototype roughly consists of MAC Hardware and MAC Software. The MAC Hardware part includes timing process, MAC transmission control, MAC reception control, and CRC/HCS process. The MAC Software part includes control of MAC signaling, network interface, and Physical (PHY) control. The designed MAC protocol will be integrated with the PHY of BWA in future and we can test overall system performance of MAC and PHY.

Occurrences of foodborne disease outbreaks are increasing in Korea. Among the outbreaks, Salmonella, Staphylococcus aureus, Vibrio parahaemolyticus are the most important organisms and meat and meat product the major sources of infection. Hazard Analysis Critical Control Point system is a process control system designed to identify and prevent microbial and other hazards in food production. It is considered to be the best process management system by the National Advisory Committee for Microbiological Criteria for Foods, the National Academy of Science, and the Codex Alimentarius Commission. The Korean Ministry of Health and Welfare established a legal basis for the implementation of the HACCP system in Article 32-2 (Hazard Analysis Critical Control Point) of the Food Sanitation Act in December 1995. The Ministry of Agriculture and Forestry has granted research funds for the development of this model system for application to traditional food products and processed fishery products as well as to raw meats. Implementation of the HACCP system is an important step and the Korean food industry and the Government are focused on ensuring food safety in Korea.

This paper describes the design and implementation of a passive transponder chip for RFID applications. Passive transponders do not have their own power supply, and therefore all power required for the operation of a passive transponder must be drawn from the field of the reader. The designed transponder consists of a full wave rectifier to generate a dc supply voltage, a 128-bit mask ROM to store the information, and Manchester coding and load modulation circuits to be used for transmitting the information from the transponder to the reader. The transponder with a size 410 x 900 ${\mu}$m$^2$ has been fabricated using 0.65 ${\mu}$m 2-poly, 2-metal CMOS process. The measurement results show the data transmission rate of 3.9 kbps at RF frequency 125 kHz.

In recent, the contactless IC card is widely used in traffic, access control system and so forth. And its use becomes a general tendency more and more because of the development of RF technology and improvement of requirement for user convenience. This paper describes the hardware module to process contactless protocol for implementation contactless IC card. And the hardware module consists of specific digital logic circuits that analyze digital signal from analog circuit and then generate data & status signal for CPU, and that convert the data from CPU into digital signal for analog circuit.

This paper presents an implementation of a gramar of Dynamic Syntax for Japanese. Dynamic Syntax is a grammar formalism which enables a parser to process a sentence in an incremental fashion, establishing the semantic representation. Currently the application of lexical rules and transition rules in Dynamic Syntax is carried out arbitrarily and this leads to inefficient parsing. This paper provides an algorithm of rule application and partitioned parsing state for efficient parsing with special reference to processing Japanese, which is one of head-final languages. At the present stage the parser is still small but can parse scrambled sentences, relative clause constructions, and embedded clauses. The parser is written in Prolog and this paper shows that the parser can process null arguments in a complex sentence in Japanese.

The objective of this study was to evaluate Environmental microbiology (EM) as a basic course for the environmental engineering program of Korea Maritime University which has been accredited by Accreditation Board for Engineering Education of Korea (ABEEK). Evaluation result of the lecture objectives was more than the average (3.5/5.0). The overall score for learning achievement assessment was more than average level of learning achievement (3.4/5.0). Interestingly, engineering design implementation regarding a specific topic as an extensive learning process has proven to be more effective (3.5/5.0). Some of effective class improvement strategies suggested were to encourage students to participate in the class with self-motivation and accountability: preview and review of the lecture, team presentation in English-speaking settings, and submitting project report written in English. In the future class of EM, test and evaluation of application capability of EM and environmental biotechnology (EB) theories to engineering problem solving should be emphasized.

While Electronic Commerce is believed to provide new opportunities and environments toward the information society, not many companies have achieved successful construction of Electronic Commerce systems regarding their own technology factors and business process types. This work provides a brief review of Electronic Commerce information infrastructure based on the technology architecture developed. Three major technologies-telecommunication, information processing, and process enhancement - support the architecture, and each major technology consists of its technical enablers. Also, the application factors of Electronic Commerce are defined and analyzed in term of inter-enterprise, intra-enterprise, and enterprise-consumer interactivity. Finally, the implementation strategy is drawn with respect to the technology architecture and three application types.
