This study developed the traceability information for tracing fishery products from the production step to the consumption step in the distribution channel of fishery products. Based on it, we further presented the theoretical linkage between traceability information and perceived qualities of internet shopping malls, and then investigated how traceability information affected trust and perceived usefulness in the internet shopping mall to find the key success factors of internet shopping malls of fishery products. We collected 194 responses from internet consumers who had prior experience on purchasing fishery products. This survey data was used to empirically test the ten research model hypotheses by using PLS. The PLS results indicated that traceability information had significant impact on trust and perceived usefulness. Finally, trust, perceived usefulness and perceived ease of use were found to be related to online consumers' intention to purchase fishery products.

The probability distribution of the repair process should be determined to choose the optimal spare level of a weapon system with a queueing model. Though most weapon systems have a multi-step repair process, previous studies use the exponential distribution for the multi-step repair process. But the PH distribution is more appropriate for this case. We utilize the PH distribution on a queueing model and solve it with MGM(Matrix Geometric Method). We derive the optimal spare level using the PH distribution and show the difference of results between the PH and exponential distribution.

The Purpose of the current study is to identify the differences between Samsung and Hyundai Group and the causes why the differences occurred. The study focuses on the founders of the two group as a main source of the differences, especially brain preference of the two founders. Two steps were employed to perform the study. Firstly, the two founders' characteristics were analyzed by using archival research. It was implicitly hypothesized that Group founders' characteristics explained the differences of the two Groups. It was found that the founder of Samsung Group, the late president Lee emphasized rationality, analysis, and cause/effect relationship and low risk taking, suggesting that he had left-brain preference. In contrast. the late president Chung, the founder of Hyundai Group, emphasized intuition, wholeness, contextual meaning, and risk taking, showing that he had right-brain preference. Secondly, a comparison between the two groups was performed in terms of business and financial risk in corporate portfolio, and management system. It was found that Hyundai Group was pursuing higher risk than Samsung Group. And it was observed that Samsung Group put more emphasis on formality in decision making and systematic control, and less emphasis on risk taking than Hyundai Group. From the two step research relationship between brian preference and management was reasoned. Research implications and limitations were discussed at the end of the study.

In order to adapt today's short product life cycle and rapid technology changes., integrated systems should be extended to support PDM (Product Data Management) or CE(Concurrent Engineering). A PDM/CE environment has been developed and a prototype is Presented in this paper. Features of the PDM/CE environment are 1) integrated product information model (IPIM) includes both data model and integrity constraints, 2) database systems are organized hierarchically so that working data C8Mot be referenced by other application systems until they are released into the global database, and 3) integrity constraints written in EXPRESS are validated both in the local databases and the global database. By keeping the integrity of the product data, undesirable propagation of illegal data to other application system can be prevented. For efficient validation, the constraints are distributed into the local and the global schemata. Separate triggering mechanisms are devised using the dependency of constraints to three different data operations, i.e., insertion, deletion, and update.

This study introduces research on the quality of medical services, optimization of medical services, dental medical services, implant medical services, and time schedules, as well as the effective process of dental implant medical services, which is expensive and requires a long treatment period. For improvement, it is suggested to evaluate using a time schedule. In this method, a time schedule is prepared in which each step, starting from the patients appointment until the completion of the treatment process, is allotted a certain time. This schedule was finalized in consultation with the employees. When performing all implant operations, the starting time of each item was checked to evaluate the degree of compliance and to understand any reasons for delay in each step. After identifying the causes for delay at each step, suitable steps to rectify the drawbacks were developed, and an optimal plan for patient management was determined. Changes in waiting time and human resource utilization were shown as concrete data, suggesting that such a schedule is meaningful as a decision-making support tool.

The adaptive accounting control system can be regarded as an realistic control system which can adapt itself to uncertain enviromental changes. It has characters that can measure the extend to which we attain our goals and give intelligence, which is essential to planning for the future and for decision making. The budget should present the aim of the compilation of the budget and synthesize the limit through the systematic plan about the utilization of resources, because is a financial plan that is used as estimate of future management operations and as a control of it. If we would like to make good use of this business budget as a tool for planning, we should try to opimize all over the business by relating business operation as far as the effective use of the economic resources in business and the supplying of it are concerned and financial budgets to the responsibility unit center. As this paper is about the budgetary management pattern of marketing based on the adaptive accounting control system, I shall begin with a description of the feature and role of responsible accounting system in management accounting. I shall also deal with the Ex ante accounting system and the Ex post optimum accounting system which are essential to the control stage of business budgeting. And finally, accounting to the control process of adaptive accounting system that fit in with the reality, I shall design a budgetary management pattern of marking section. I wish this paper would be helpful to the activity of budgetary management. A budget is an important step of diverging point. Consequently, when we set up a budgetary pattern based on the adaptive accounting system as far as the control accounting is concerned. I believe that the step of responsible accounting will be a more elaborate and scientific step of management.

Many countries of the world is driving forward development of large-scale hub port. They are now pushing ahead with setting up of effective marketing strategies to survive in keen competitions of the 21st century port industry. The port is of ever increasing importance for the bridge connecting sea and road transportation in handling international cargoes. The port, differently from general working places, is a closed area required for security, customs, and quarantine procedures. The loading and unloading is being done differently by ports, cargoes, and ships. To do loading and unloading, a lot of equipment and different types of labor are required, which flow is complicated and safe management is essential. As above mentioned the port is very unique and very deteriorated working place in its working environment. The purpose of this study is to propose ways to reduce and prevent from port accidents. As first step to do this, we have collected 923 accidents happened at Incheon Port during the period of 1994 to 2003. We have thoroughly analyzed characteristics, harmfulness, and risk of the loading/unloading they have done, as well as the accident frequency and relationship between the accidents. As second step to further analyze, We have employed DMAIC technology, an advanced process of 6 sigma presently in spotlight as the best program for management innovation. This analysis results in recognition of important accident characteristics, causes and effects analysis, critical causes of accident, and suggestions to decrease accidents.

Failure to link business or operations strategy with the activities of operations is a critical problem in strategy implementation process. This problem comes from malfunction of a coordination and control mechanism to support the strategic direction by effective communication throughout the firm. A performance measurement and evaluation system (PMES) is thought as a core mechanism to monitor, direct. and induce desirable activities. We have developed a new strategic PMES (SPMES) that can effectively support the manufacturing strategy by utilizing customized performance measures. They are selected from a pool of four distinct but closely related sets of performance measures; financial, market, internal competency, and performance driver. In this paper, we briefly review the structure of the SPMES and explain the change process of PMES into SPMES in manufacturing business units. First we analyze the business environment and manufacturing strategy to identify short- and long-term issues facing the management. Next step is scrutinizing the objectives and activities of every function and process in the business unit. Using the information obtained, we can diagnose the gaps between currently effective PMES and desirable SPMES supporting the strategies. Once the problems in existing system are identified, we reconfigure the existing and new measures to establish a SPMES through a series of analyses, discussions and workshops. In organizing the selected measures in the new system, we use AHP method to reflect the relative importance of the measures in a specific business. Finally, modification or development of information system to support the SPMES wraps up the development process, and implementation begins. We explain the entire process using two cases to clarify the real meanings and the difficulties of PMES change process.

True process collaboration can be accomplished through seamless integration of business processes and enterprise knowledge. Therefore, it is natural that the concept of Business Operating System (BOS), proposed by Delphi Group in 1994, is currently considered as a next evolutionary step for Business Process Management System (BPMS). Literature reports very little work, however, especially, on a comprehensive architecture of the system. This paper proposes an architecture of BOS with the following definition: ' BOS is an intelligent activity supporting system that provides a comprehensive and personalized work environment to each knowledge-intensive worker. ' To propose an architecture of BOS, the paper first identifies and classifies functional requirements for Business Operating System. Then, it proposes a data model and an architecture of the system to satisfy the functional requirements. The proposed architecture focuses on two essential technical requirements. First, the system should provide an effective means to integrate data and processes and to standardize distributed component systems. Secondly, the system should also be intelligent enough to assist workers to perform their knowledge-intensive work. The paper shows how these requirements can be achieved by using Semantic Web and Web Service.
