ABC analysis is the process of dividing inventory items into three classes according to their monetary usage so that managers can focus on items that have the highest monetary usage value, and has been widely used in practice since its development in 1950. However, the original criterion, monetary usage value, can no longer be the only rational criterion. Applying Analytic Hierarchy Process, we develop a new method to classify inventory items by considering such operationally/strategically important criteria as annual dollar usage, lead time, supplier's capacity, defective rate, difficulty of purchasing and unit price. A case study is performed applying the method to the field data from a company which produces electrochemical products.

In this study, interest in rural life of good natural environment rather than busy life is increasing as human life is extended by scientific and medical technology and society has improved. The reckless development of rural villages has caused social problems as the natural environment has been damaged, failing to function as a pleasant home. To address these problems, the government has implemented a rural village development project, but if the site is selected incorrectly, the residents may not be recruited, or applicants may lose their status, or the portion of the infrastructure building fee may increase. In order to prepare objective and clear assessment methods for the target site not to cause such problems, a layering analysis method (AHP: Analytic Method) was used to identify the current status of the rural village formation project, draw assessment items, and determine the importance of each item.

In this study, an analysis was performed using the growth data and environment data of Korean melon farmers to confirm the influence of environmental factors variables on fruit weight of Korean melon. The analysis results can be summarized as follows. First, it was confirmed that humidity and temperature were recognized as the most important factors among the core factors of korean melon farm production management. Second, The correlation analysis of fruit weight and environmental factors showed a statistically significant soil temperature, internal humidity. Third, The Pooled OLS model estimation results showed that the estimation coefficient for soil temperature is (-), and the estimation coefficient for soil temperature square is (+), indicating that optimal control temperature exists.

1990년 중반 이후 외국계 기업과 국내 대기업의 적극적인 유통산업진출은 중소 소매업을 어렵게 하고 있다. 또한 대기업 편의점의 급속한 확장 역시 골목상권 환경을 열악하게 하여, 중소 소매업 점포수의 폐점을 가속화하고 있다. 2003년 중소 소매업의 경쟁력 강화 및 자생력을 확보하고자 정부는 중소유통공동도매물류센터(이하, 중소유통물류센터)를 건립하였다. 하지만 급변하는 유통환경과 온라인 쇼핑의 급속한 발전 속에서 중소유통물류센터는 갈수록 점점 어려워지는 현상에서 중소유통물류센터의 역량강화를 위한 현상분석 및 문제점 도출을 통하여 경쟁력 강화 및 효율적 운영방안을 위한 전략을 제시하고자 한다.

This paper presents the overall valuation framework of the Army Tactical Command Information System(ATCIS) with its empirical data which is developed by the ROK Army in 2005 with its own R&D efforts over the past 10 years. The valuation with the appropriate methods is conducted through the full and relentless support of ROK Army HQs, defense agencies, and related firms. And the results include both qualitative and quantitative values of the ATCIS in perspectives of economic, technical, and defense strength effects. As a result, the development of ATCIS is valued over 1.7291 trillion Won which is over 6.55 times benefit and cost ratio comparing with other country's similar system. The worth of this paper includes the actual framework and methods to apply the valuation of other weapon systems and its preliminary research, defense offset valuation, performance evaluation and others.

The primary purpose of this study is firstly, to ascertain the suitability of the IT BSC (balanced scorecard) methodology for the performance analysis of EGIS(environment geographic information system), secondly, to analyze the outcome of EGIS using the methodology, and finally to present guidelines for effectively managing the performance of EGIS. This study has rebuilt the IT BSC methodology based on the previous study on the performance analysis of GIS and EGIS whose performance over the past five years has been evaluated. According to the analysis, the integrated performance is estimated at 105.3 points. This figure indicates that the cumulative performance of EGIS is more than the baseline of goal, 100.0 points. The feature of this study is to develop a new methodology suitable for the EGIS performance analysis and to evaluate and quantify the total performance of EGIS objectively through the application of the new methodology.

Recently, several number of Multi-Intermodal Transfer Center are nominated to improve convenience of public transportation user. Due to budget constraints, it should be defined which is the first consideration among the discussed many works. In this circumstance, there are some absurdities in the evaluation of validity of existing methods. Therefore, we suggested the Priority Order Valuation for Multi-Intermodal Transfer Centerer. The evaluation method, we suggested, is considered quantitative analysis and qualitative analysis. In this study, we find out that B/C ratio and construction costs are strongly related to the quantitative analysis so that Multi-Intermodal Transfer Centers in metropolitan area are evaluated the positive results. Therefore, both quantitative analysis and qualitative analysis are applied to the Priority Order, metropolitan area and other area are fairly evaluated the results for the Priority Order.

High-rise building is taking a place as one of building types from apartment housings to commercial buildings. With taking in account of stability and durability, strength of used materials is increasing gradually in these high-rise buildings. According to this, frequency in use of SD500 re-bar is increasing gradually in high-rise buildings. However the study of SD500 re-bar is insufficient because SD500 re-bar started to be used for domestic buildings lately. Specially because there is no guide or study to refer to, people get into difficulties when to decide the method of re-bar connection in construction using SD500 re-bar. Accordingly in this study, it suggests the method of estimating the economical efficiency on SD500 re-bar connection, and conducts benefit/ cost analysis on lapped splice and coupler splice by applying AHP theory, and then presents its result. After to analyze re-bar diameter of D25, 29, and 32, finally we attained the result that the coupler splice is advantageous in all parts of benefit/ cost more than the lapped splice.
