This study estimates gender wage gap by the Korean industries. The empirical findings are as follows: 1. The sex segregation by industries has not improved. 2. The average wage in $\ulcorner$electricity, transportation, warehousing, financial institutions$\lrcorner$ is relatively higher than others. On the contrary, the average wage in $\ulcorner$mining and manufacturing$\lrcorner$ and $\ulcorner$wholesale and retail, food, loading$\lrcorner$ is relatively lower than others. 3. The gender wage gap in $\ulcorner$electricity, transportation, warehousing, financial institutions$\lrcorner$ is relatively lower than others. On the contrary, the gender wage gap in $\ulcorner$mining and manufacturing$\lrcorner$ is relatively higher than others. The gender wage gap has declined annually. The gender wage gap in industries with lower wage level is higher. The decline of gender wage gap cannot be interpreted as a relaxation of sexual discrimination.

We propose an Executive Information Systems (EIS) Architecture for chief officers of the Air Force using data warehousing method. This architecture has two main proposes. The one is to provide the information for chief officers to control and command their organizations effectively by analyzing operation data at normal times. The other is to provide chief officers with the information about current situation so that they may make right and rapid decisions at emergency. The architecture introduced here is one that analyzes operational trends as well as current trends in a hierarchical organization environment. System analysis and design techniques for the Air Force EIS such as data flow diagram, system structure, entity-relational diagram, and third normal form of relational database were presented. After prototype screens are demonstrated, benefits of new EIS architecture were also discussed as a conclusion.

This paper deals with the design problem of a man-on-board(MOB) storage and retrieval warehousing system which is suitable for storing items of small size and light weight. It is assumed that the operator carries out a sequence of retrieving(or storing) operations traveling on a specially designed truck. Considering the operating characteristics of the man-on-board system, an optimal design model is developed in which the investment and maintenance costs of the system are minimized over a time horizon satisfying a set of constructional restrictions. The model is formulated as a nonlinear integer program and a search algorithm is proposed to find an optimum solution.

On processing of the shipbuilding, Various steel plates are used as the important material in many fields including the shell plate, a structure, etc. Therefore, the proper steel plate management system like a warehousing, pile, delivery is very important. Presently Operators manage the steel plate by using the software program, but they manage many parts manually, so many problems are generated on the steel plate check, management, and operator safety. In order to solve this problem, we developed Auto Steel-Plate Piling System. Also this system automatically manages and traces the steel-plate from warehousing to delivery.

To compute the expected travel time of storage and retrieval (S/R) machine in automated warehousing systems most of the previous studies assumed that equal number of rack openings are required regardless of the nature of storage assignment rules. It is known that randomized storage assignment rule usually needs less storage to space than needed for full turnover-based assignment rule. The objective of this paper is compute the expected travel time of each assignment rule more equitably by taking into account the storage space required for each rule. First, the rack storage space is determined which satisfies a given service level. Then based on the standard Economic Ordering Quantity model, trade-off analysis is carried out which relates the storage space to the expected travel time of the S/R machine. Finally, example problems are solved to compare the performance of each assignment rule under varying conditions of demand pattern and service level.

Intranet is information technology for information sharing and collaborative work in geographically dispersed organizations, and has clear potentials to combine with other information technologies such as data warehousing and knowledge management. Data warehousing make it possible that the data stored for business analysis can most effectively be accessed by separating it from the data in the operational systems, and knowledge management is the paradigm to make the enterprise realize the best value of its knowledge assets, This paper is to suggest an architecture of knowledge sharing to combine knowledge management with data warehouse under the Intranet environment for the purpose of achieving the competitive advantages through the effective decision making in the modern companies, This paper also addresses the steps to implement this architecture.

This paper, realizes the design of the sequential controller of a reinforced warehousing-delivery and unmanned transportation system for automated warehouse system. The system is composed of ware housing delivery adn transportation system using two unmanned vehicles with hierachical structure. It is described by GRAFCET and realized by programmed logic with microprocessor. Being described by GRAFCET, the system is able to divide it into subsystems and to synchronize them. Defining the concept of program module, one can easily program the system with the microprocessor instruction language.

세계적으로 기후변화와 자원 고갈, 빈곤, 인권 등의 문제들이 갈수록 심각해지고 있으며, 경쟁심화로 인한 기업의 극단적 이윤 추구가 도리어 기업의 생존마저 위협하는 원인이 되고 있다. 이에 기업의 환경적, 사회적 책임에 대한 이해관계자의 요구가 커지면서 그동안 기업의 경영 목표였던 이윤 추구만으로는 더 이상 기업의 존립을 보장할 수 없는 인식이 확산되면서, 지속가능경영은 중요한 경영전략이 되었다. 공급사슬망 속의 물류창고업에 있어서도 기업 간의 협력, 상호작용, 연계로 이루어진 공급사슬망의 연계발전을 위한 지속가능경영은 큰 의미를 지닌다고 할 수 있다. 본 연구는 전체 공급사슬망 상의 물류산업 중 지속가능경영이 취약한 물류창고업에 대해 지속가능경영 활동이 고객인 보관위탁 화주, 복합운송주선인 등에게 미치는 영향에 대하여 분석하고 이러한 고객의 만족이 기업의 신뢰에 어떠한 영향을 미치는가에 대하여 실증적으로 분석하였다.

In this paper, we review and classify shopping information services for electronic commerce in Korea. Shopping information services for electronic commerce can be divided into shopping mall information service and product information service. Shopping mall information service simply shows and suggests information on the shopping malls that it has in its data store. But product information service provides information about the items of the shopping malls the service has and therefore gives more powerful and convenient interfaces to users. Cutting-edge product information services can perform online comparison shopping facility, which searches and compares the items what the users want on the reasonable basis of economical criteria, such as price. Books, CDs, and Personal Data Assistant(PDA)s are the products of which the specification is clear enough to be described on the Web. And the comparison of the products by the information service is performed on the basis of "price" of the product item. The approach to design and implement product information service can be divided into two categories. The one is an application of data warehousing mechanism, which stores the product information on the regular basis of time and provide it when the users query over the Web-database gateway. The other approach is a shopping agent mechanism, which stores information on "how to shop" and the shopping agent collects the information of product items just after users query about the product and provide the information in real time or notify them by alerting service. Thirty nine shopping information services are compared and classified in this paper and they are extracted from "Naver" and "Yahoo! Korea". The final result shows that most services are just a simple shopping mall information service in growing stage, product information services with data warehousing are lack in product ontology in middle stage, and that product information services with shopping agent are in early stage.
