IHWA는 기존의 객체 컴포넌트를 통합함으로써 새로운 응용프로그램을 작성할 수 있는 CBSE(Component Based Software Engineering ) 기법을 바탕으로 개발되어진 웹 기반 정보 저장/검색 시스템이다. 이 시스템은 1997년에 그 1차 버전이 개발되어 사용되어 왔으며 현재는 보다 나은 견고함과 일반성의 제공, 그리고 전자상거래 영역에 대한 준비를 위해 시스템에 대한 중요한 수정작업이 진행중에 있다. 본 논문에서는 새로운 IHWA시스템의 설계에 적용된 원리 및 내용을 설명하고 특히 정보수집 서비스를 제공하기 위해 필수적으로 요구되는 정보 수집기들의 구조 및 구현에 대해 설명하고자한다.

This paper proposes a method for designing stacking warehouses of pyramid type which can be found in storage rooms for steel coils, paper rolls, and drums for oils. Formulas were derived for estimating the expected travel time of cranes and the expected time for rehandling activities. Based on the derived formulas, this study derives the cost function for determining the optimal numbers of rows, bays, tiers of stacks under the condition that the requirement for storage space is satisfied. Numerical examples were given.

실체뷰는 대량의 데이터웨어하우스에서 질의처리를 효과적으로 수행하기위한 대안으로서, 그 핵심은 각 데이터 원천에서의 데이터변화에 대응한 복합적인 뷰의 효과적인 관리 문제이다. 본 연구에서는 우선 실체뷰 관리에 관한 기존의 연구들을 일별함에 있어서 즉, 갱신의 주체문제, 갱신객체, 및 갱신시간 문제의 세가지 관점에서 본 연구의 위치를 결정한 다음, 대수적 접근법으로 복합뷰 갱신문제가 복잡해지는 원인을 규명하였다. 그 해법으로서 참조무결성을 활용한 복합 조인뷰의 갱신 알고리즘을 제안하면서, 여러 가지 참조무결성 제약조건과 트랜잭션과 관련된 자체갱신적 새로운 해법을 제시했다.

데이터베이스에 저장된 수많은 자료들을 사용자의 질의에 맞추어 웹상에서 표현해주는 것이 바로 리포팅 툴의 역할이다. 그에 관한 연구들로 인해서 EASY BASE, ReportShop 과 같은 여러 리포팅 툴들이 상용화되고 있다. 하지만 사용자가 보다 쉽고 직관적으로 XML문서를 작성하고 관리할 수 있는 툴들은 미흡한게 사실이다. 이 논문에서는 리포팅 툴의 기본이 되는 쿼리 결과를 웹상에서 표현해주는 xml 을 설계하였다.

Many studies are being applied for various parts of USN (Ubiquitous Sensor Network) technology. The world's large retail stores and warehouses that apply logistic management are also studied. With this, USN technology is increasing in its utilization. However, to handle and process real-time data will never be never easy if these huge warehouses are using too many sensors, and real-time data correction is almost impossible. Software implementation and high-speed hardware are insufficient to solve these complex problems. To solve this problem, a key solution is to implement high-speed software. Hence, this paper suggests a USN logistics management system that applies pipelining techniques for efficiency in real-time data correction and reduces errors of generated values.

In order to decrease the number of handles, speed up retrieval operations, and manage products efficiently, the investment of facilities such as the installation of the storage equipment and the enlargement of the storage area may be attempted. However, the same objectives can be accomplished by utilizing the existing storage area efficiently. In many types of storage facilities, because of the limitation of storage areas, products are usually piled up, which may cause rehandles of inventories. Rehandles influence significantly the handling efficiency of warehouses. This study develops methods for minimizing rehandles of inventories to improve the operational efficiency of warehouses. A mixed storage problem is addressed for minimizing the expected number of rehandles. Optimization models are proposed and the genetic algorithm is applied to solve the problem.

We surveyed the sanitary conditions for 17 cold and frozen food storage warehouses in Korea, using the following 5 inspections items: "putting into warehouse (A)", "prevention of cross-contamination (B)", "storage management (C)", "temperature control (D)", and "management of records and documents (E)", We included 20 detailed items. The results of distribution for frequency by five major inspection items showed that "(E)" was the highest, the next "(D)", "(C)"; and "(B)" was the lowest. In the correlation of inspection scores between total scores, "(B)" and "(C)" were highly related to the total score, therefore, the higher score of "(B)" or "(C)", the higher for the total score. In details of inspection items, "the management of cross-contamination upon taking product out of the warehouse" had the lowest score with a mean, of $2.67{\pm}1.80$, and also ranked as first of the 20 items.

Purpose - In general, large companies have larger organizations, funds, and systems to provide more effective and efficient services in the market. However, development needs to support the livelihood of ordinary citizens who work for small businesses as well. This research suggests that a new distribution channel, called a "foothold style Kosa mart," that cooperates jointly with a distribution center and a large discount mart can provide direct solutions to small and mid-size distributors. This new distribution channel can achieve a limited type of "Nadle shop (small supermarket) foster project" related to building a joint distribution center and improvement in wholesale supply. Research design, data, and methodology - Data about the Korea distribution situation, the Nadle stores, and the logistics centers were collected from literature, Statistics Korea, journals, and reports. Specifically, we investigated information about Kosa Mart and Nadle stores. We focused on the redesign of the distribution center for the Nadle store. Results - The Kosa Mart distribution center now includes 18 warehouses, and has been handling 2000-3000 items. Most of the warehouses have been simply designed and items loaded and stored without refrigeration; thus, it is possible to store only products of certain manufactured goods. The current logistics center has no wholesale function because it failed to resolve the joint purchasing and product supply issues of competitively priced products. Conclusions - This study aimed to identify ways to strengthen the competitiveness of small- and medium-sized retailers. A Kosa Mart redesign aims to unifying the logistics center, stores, and customers. First, the joint wholesale logistics system, equipped with an integrated ordering system, needs to process customer orders and store orders at the same time. Second, excellent small business product development has to connect with production. Third, the store composition needs to support a shipping hub. Fourth, the Mart differentiates itself from convenience store goods by supplying regional and specialized products to customers. Fifth, a service buying agent and direct transactions between producers and consumers need to be established, and exhibits and displays of goods need to be improved.

This investigation aims to provide basic data for rural village planning and rehabilitation planning. Public infrastructures of forty selected villages have been surveyed. Provision of facilities, user satisfaction, perceived problems, and conditions of maintenance have been surveyed for three classified types of infrastructures; 1) public utility spaces such as community hall, and parking lots, 2) public production infrastructures such as warehouses, and irrigation facilities, and 3) public infrastructures for living environments such as roads, water supply, and sewage system. All twenty smaller villages (ki-cho-ma-ul) had problems of poor conditions and insufficient spaces with community halls. Most of the smaller villages suffered from lack of public production infrastructures, or had problems of insufficient spaces and poor maintenance conditions. They also lacked good access roads with adequate right of ways. Only three villages were provided with sewage systems. In the twenty larger villages (myun-bo-ma-ul), though public utility spaces were provided for most of them (as an example, sixteen villages had welfare centers), they were not large enough and they were maintained in poor condition too. On the one hand twelve of the larger villages had farm machine service centers, only a few villages were equipped with warehouses. Many more public infrastructures for living environments were found in larger villages. However, only a few villages had pollution control facilities. Multidimensional scaling revealed groups of distinctive characteristics, in terms of public infrastructures, among smaller villages. It did not show any noticeable distinctions among larger villages.
