Extending the success of the Tropical Rainfall Measuring Mission (TRMM), the spaceborne measurement of precipitation by Global Precipitation Measurement (GPM) is initiated. The GPM consists of a core satellite which will have a dual-frequency precipitation radar (DPR) and a constellation of small satellites equipped with microwave radiometers. The GPM is inherently a global program. Responding to the GPM plan, many other nations are much interested in participating in the GPM team or simply utilizing GPM products aiming at the development of meteorological technology. Korea can fully function its role if Korea is selected as a CAL/VAL site for the GPM because Korea maintains a well-established dense rain gauge network (AWS), precipitation radars, and the Haenam super site for surface observation. In this feasibility study, the necessities of the GPM project in the context of academical and social backgrounds and associated international and domestic activities are investigated. And GPM-related core technologies and application areas are defined. As a result, it is found that GPM will represent a great opportunity for us because of its ability to provide not only much enhanced three-hourly global rain products but also very useful tools for the enhancement of weather forecasting capabilities, management of water resources, development and implementation of monitoring techniques for severe weather phenomena, agricultural managements and climate application. Furthermore, rain retrieval and CAL/VAL technologies obtained during the involvement in the international GPM project will serve as basic knowledges to run our own geostationary satellite program.

The purpose of this study was to set related variables for leadership measurement in the leader of a community organization as an effort to Community development constantly. Therefore, in this study, first, various theories on leadership were reviewed. Second, approaches and variable relationships were reviewed by leadership theory study. Third, leadership measurement variables were set based on Bass's Transformational theory, one of new trend theory, to measure the leadership of the community organization leader. As a follow up, clear and scientific analysis, through empirical analysis, based on the variables set in this study will be made to measure leadership of a community organization after creating investigation tools based on the variables set in this study A literature study was mainly used. 'Human Behavior' by Dr Han-geom Lee, 'Leadership Theory' by Eung-seop Shin, many other related books, articles of the Human Relation Organization Association, and theses and Bass's writings. Major findings of this study, through the literature study, were as follows. As conventional leadership theories, characteristics theory, behavior theory and situational leadership theory were proposed. First, characteristics theory searches the characteristics of an effective leader. It proposes that effective leaders and ineffective leaders have different characteristics, respectively. Therefore, it proposes to study the leader's characteristics. However, there is not a flexed definition for leader's characteristics. Scholars make different definition on leader's characteristics, and they are very subjective. Thus it cannot be a valid theory. Second, behavior theory describes how the leader behaves to his fellows. It studies leader's behavior focusing on what type and what combination is the most effective in all situations. However, it has weakness in that it focuses on a leader's behavior only, and ignores the situational features. Third, situational theory describes the relationship between leadership type and situation. It suggests that there is not a single leadership style that can suit all situations. It emphasizes the relationship between leadership type and situation. Although situational theory considers more variables than characteristics theory or behavior theory, it also sees situations as static and flxed. Although Fiedler's theory tried to comply with situations, he did not analyze interactions between a leader and his fellows.

Main research question of this study is based on situational gap between donation motivation and behaviour in non-profit organization. However, researches investigating the gap were limited. Therefore, this study examined components of psychological variables. Specially, we proposed the variables about consumer's impulsive motivation or behavior on impulse literature in donation toward non-profit organization. This study conducted a scale development to measure consumer's charity donation impulse based on non-conscious viewpoint. For the development of measurement tool for charity donation impulse, we conducted two stages of research process. First, the measurement items of charity donation impulse were developed through FGI and in-depth interview on experts. Secondly, the factor analysis was performed, and then some items were eliminated through this analysis. As a result, we found the final scale with 26 items, which were named as evaluation sensitivity charity impulse, reward sensitivity charity impulse, functional impulse, non-planning charity impulse. These results showed that the measurement items developed in this study were confirmed to be useful tools for measuring charity donation impulse.

Purpose - Over 90% of Domestic logistics industry is small enterprise and they are experiencing growth stagnation due to price-based competition structure rather than constructing logistics service of high added value. In order to get over this situation and pursue the development of logistics industry, strengthening its competitiveness, through inter-enterprise cooperative network build-up, would be a key alternative. Therefore, in this study, an index for measuring inter-enterprise cooperation level of Joint logistics business will be developed as a typical collaborative business model in logistics industry. Moreover, a strengthening competitiveness method suggests a developmental step and a key management index to mature in logistics industry. Research Design, Data, Methodology - This study is an index development research for measuring inter-enterprise cooperation level of logistics industry. Such a level was measured by performing a survey by targeting enterprises that participated in Joint logistics business. The targeting enterprises are typical cooperative models in logistics industry. Measurement items were developed which were based on the presented items in existing research. Question items were composed of selection type questions as answering Yes/No. They measures implementation status of corporate activity and detailed activity items measuring qualitative level. Total samples were based on 116 enterprise samples including 90 logistics enterprises and 26 shippers. In addition, by evaluating the importance for Joint logistics business recognition with personnel working level, the weight of measuring variable was extracted. This study has built an assessment tools (LPCI) on Joint logistics business cooperation level in a situation where there are no previous studies on joint logistics business, this study is meaningful for other studies. Results - As a result of analyzing LPCI presented in this study, the score of logistics enterprise was represented as 59.9 points based on full score of 100 points and that of shippers as 47.2 points and cooperation level among enterprises participated in Joint logistics business was revealed to be very low. In particular, as a result of measuring the importance between logistics enterprise and shippers, the difference by each measurement standard was represented among those enterprises. This difference is considered to be a key factor that cooperative operational conformity between logistics enterprises and shippers is represented to be low. Conclusions - As most joint logistics business, being promoted at present, is sharing facility and information with joint logistics business, it is hard to find such a joint logistics business in reality based on cooperative business model in main cooperation agents. Therefore, competitiveness of logistics industry could be strengthened by promoting joint logistics business based on their mutual cooperation among enterprises. In other words, it is to secure sustainable competitiveness of joint logistics business together with creation of new market by inter-enterprise cooperation based on integration of basic logistics business.

In the age where the Internet changes everything, even the earth has become flat. The boarders between nations, locations, times, and industries are not maningful, and no single company can do the whole process well. Therefore, various types of 'Value network' and 'Relation web' emerge for moving first and fast learning. Bort the relationship maturity model (RMM) proposed and the partnership management initiatives at SKT demonstrate that the concept is important, and that the final goal can be reached only through a series of critical outcome at each phase. In particular, recognizing as core infrastructures various online/offline channels, deep trust, and rich communications is an important finding for a successful relationship management. Also, related literatures suggest the following key factors to be influential in more that two phases: professionalism including expertise, similarity, channel capacity. Based on these findings, future efforts need to be put on the research & development of related measurement and management tools. We do hope more people dance with their partners through these efforts.

Springback, an elastic material recovery after the unloading of stamping tools, causes variations and inconsistencies of final part dimensions. Recently, narrow and long surround molding parts around door frame are applied to high grade automobiles, but there are great difficulties in their die development, construction and tryout because of several springback modes including vertical movement and twist during flange forming process of them. So it is very important to predict springback's quantities of a surround molding part and, moreover, to compensate the die for them adequately, when they can't be corrected by the restrike operation. This paper presents a case study based on the die design for a surround molding part made of stainless steel. The forming and springback predictions, carried out using PAMSTAMP 2G, are reported and compared with the measurement data of the prototype. The predicted springback results were acceptable, so the processes of compensating die using Automatic Die Compensation Module of PAMSTAMP 2G were performed iteratively until the tolerances between the designed shape and the simulation data were satisfied.
