송학진,박영호,이만웅 동의공업대학 2001 論文集 Vol.27 No.1

In this study, we establish bootstrap control limits for EWMA chart by applying the bootstrap method, called resampling, which could not demand assumptions about pre-distribution when the process is skewed and/or the normality assumption is doubt. The results obtained in this study are summarized as follows : bootstrap EWMA control chart is developed for applying bootstrap method to EWMA chart, which is more sensitive to small shifts of process. With the purpose of eliminating a skewness of the resampling distribution, the bootstrap control limits are established by using a modified residual, and its performance is analyzed by ARL. It is shown that the bootstrap EWMA control chart developed in this study includes the properties of standard EWMA control chart that is sensitive to a small shift, and detects process in out of control more quickly than standard EWMA chart.

This paper aims to examine and analyze the merits and demerits of the existing evaluation models and to contribute to the practical applications of the evaluation models appropriate to both business and public organization. This study classifies the existing models into four categories based on the criteria as follows ; 1) the characteristics of the model ; 2) the stepwise decision making ; 3) the ovjective ; 4) the development process. Furthermore, these models are divided into the following groups on the basis of the evaluation purpose ; 1) the screening model ; 2) the prioritizing model ; 3) the resource allocation model ; 4) the compound application model. This study is to study and aggregation model which enables the project manager to make a rational decision in project selection. The aggregation model is divided into sub-models according to the evaluation objects ; DAHS, DAHP, and DAHR model. DAHS model is for the screening of the proposed projects by using scoring methods based on Delphi and AHP methods. This sub-model is appropriate for eliminating the most undesirable from further consideration. DAHP model is for prioritizing the screened candidates. For the measure of goodness, the priority vectors are calculated (or generated) using AHP and Delphi method. DAHR model is studied by this paper for the R/D resource allocation using LP and 0-1 programming. This sub-model uses a utility value calculated by the priority vectors. The aggregation model is applied to the evaluation of a public research institute projects with a series of real data. Several conclusions are drawn from the analysis and evaluation of the projects. The DAHS model solves the problems posed by the subjectivity in determination of evaluating factors and their weights, which prevails in existing evaluation models. The priority of R & D project is decided by the of DAHP model, which makes mutual comparisions of the concerned elements. Therefore DAHP model is considered to be more rational than the existing ones. DAHR model helps to distribute the R & D resources effectively by means of LP and 0-1 programings using priority vector. The application of the priority vector for LP and 0-1 programmings according to partial or total implementation eases much of difficulties in computing the extent of contribution. Especially proposed model is known the be appropriate to eliminate the factors of subjective evaluation. In conclusion, proposed model is considered to be useful in practically serving the purpose of evaluation R & D projects for both business and public organizations.

김상길,송학진 동의공업대학 2001 論文集 Vol.27 No.1

The purpose of this paper is to overview the development process of Korean Foreign Direct Investment and identify some problems arising from those entries into foreign countries, especially Southeast Asian Region including Vietnam and explore Korean companies' strategies to enter into those markets by means of FDI. Korean firms must consider linkages via FDI to be a strategic choice that enhances their competitiveness in a globalized market, rather than a profit-seeking motive aimed at extracting economic rent from a foreign market. Korean firms should build up firm-specific advantage based on core competence that have application in a variety of areas to provide a broad base for expansion, be widely leveraged and lower country risk. To gain competitive advantage in foreign markets, Korean companies take a prudent consideration of their strategy and structure, factor conditions, market conditions and related and supporting industries.

A plant health monitoring method based on a plant microbial fuel cell (PMFC) technique was investigated. The reducing action of plant exudates on electrochemically active bacteria (EAB) in the rhizosphere was used as the basis of the method. Ardisia pusilla was used as an experimental plant. The results indicated that the open circuit potential (OCP) development from the PMFC is closely related to plant health and affected by the cultivation environment. Distinctive OCP developments were observed using the PMFC with live, dead (heat shocked), or no plant. Cultivation conditions such as watering, fertilizing, temperature variation, and lighting affected OCP development from the PMFC. Plant root viability analysis indicated that OCP development from the PMFC is closely related to plant health. These results suggest that this method based on the PMFC technique is a facile, cost-effective, and rapid tool for monitoring plant health.

Purpose: This study aimed to investigate the optimal collection time of Acer palmatum extract (APE) through anti-oxidant and anti-bacterial activities. Methods: We confirmed the anti-oxidant activity of APE by estimating the total polyphenol content, total flavonoid content, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging effect, and cell viability. In addition, we determined anti-bacterial activities against Staphylococcus aureus, Bacillus subtilis, and Pseudomonas aeruginosa during growth. Results: Anti-oxidant activities of APE peaked in July and November. RAW 264.7 displayed high cell viability in APE concentrations of 5–100 µg/mL in July and November. As a result of conducting anti-bacterial activities, seasonal variation of APE against three bacteria was exhibited. Conclusion: The anti-oxidant and anti-bacterial activities of APE showed seasonal variation, and high cell viability in July and November; therefore, consideration of the optimal seasonal collection time for Acer palmatum could be an important factor attributing to its natural antioxidant properties and the optimal collection time was confirmed especially to be in July and November.
