  • This article discusses the findings of an empirical study conducted on 62 large organizations. The major purpose of the study was to analyze the relationship of Information System Resources distribution between the system plan control and system development and system operation. In this study information system resource is broadly Identified by computer hardware, software, data, procedure, operator. Because of the real centralization/decentralization issue facing organizations is much broader then the choice between alternative computer hardware configurations. And there are three separate resources of the information system that can be decentralized system plan and control, system development, system operations. The decision regarding how to organize each of these three separate resources is based on a different set of criteria. Furthermore, each decision can be made relatively independently of the others. In this article the results of a study are indicated below. In the degree of decentralization of information system resources between system plan control and system development and system operations were found the positive relationship. Therefore, the more information system resources are decentralized in the one dimension, the more information system resources are decentralized in the other dimensions, and the more information system resources are centralized in the one dimension, the more information system resources are centralized in the other dimensions.

  • As the world's attention turns to sustainability and the considerations of cumulative effects, the concept of Strategic Environmental Assessment(SEA) has become more significant and urgent and increasing number of countries and international organizations now undertake some forms of SEA. The term SEA, however, is variously defined and understood; generally it means a formal process of systematic analysis of the environmental effects on development policies, plans, programmes and other proposed strategic actions. This process extends the aims and principles of EIA upstream in the decision-making process, beyond the project level in which major alternatives are still open. There is a shift toward more integrative approaches and greater use of Environmental Impact Assessment (EIA) and Strategic Environmental Assessment (SEA) as sustainability tools in cooperation with Environmental Management System (EMS). Currently, Korea has EIA system and Prior Environmental Review System (PERS) which is different type of SEA as Environment Assessment (EA) system. APEMI IA MODEL integrated following three pillar(refer to attached figure.1) ; First pillar symbolized decision making cycle with planning process. Second pillar symbolized integrated assessment which tying SEA and EIA with specific impacts assessment(eg: social impact assessment, economic impact assessment, health impact assessment etc) in cooperation with EMS. Third pillar symbolized EA best practical procedure of International Association for Impact Assessment(IAIA). Considering the above, we applied new conceptual model(APEMI IA MODEL) into Impact Assessment for better integrated decision-making in KOREA as an alternative IA system(IS IA MODEL A and B refer to attached figure 4, 5).

  • As the management of fuel efficiency becomes globally reinforced in attempts to find an environment-friendly vehicle that will operate against global warming, the interest in and the demand for the type of vehicle with a high-efficiency diesel engine using light oil. However, it also emits a greater amount of PM (particulate matter) and NOx than emissions from vehicles using other types of fuels. Therefore, the DME (Dimethyl Ether), an oxygen containing fuel draws attention as an alternative fuel for light oil that can be used for diesel engines since it generates very little smoke. But to develop and compare performance of an electric controlled common-rail DME engine, engine tests requires optimized injection conditions at required engine RPM and engine torque. These injection conditions cannot be set freely and the data configuration through the experimentally repeated application requires much time as well as a significant amount of errors and effort. The object of this study is to configure the basic injection map using the results of the DME engine experiments performed so far. For this, in this study, the functionalization of the required equations were performed along with the basic review of the factors that had influence on the data map. Through this, the information on the injection pressure, injection amount, injection duration, injection timing, etc. under certain operation condition could be obtained.

  • If the medical staff privileges, which mean the eligibility to practice at open hospitals, are excluded in the United States, antitrust claims based on the violation of the Sherman Act have been raised a lot. The proliferation of these lawsuits in the United States, which are characterized as antitrust lawsuits, can be understandable situation. The reason is because doctors who don't belong to specific hospitals are seriously damaged, if the medical staff privileges are excluded and doctors cannot use facilities of open hospitals. In order to decide to allow the privileges of certain doctors, hospitals have to rely on peer review to maintain high quality of medical services, and it is not easy to find alternative of peer review in the professional areas like healthcare. However, there are possibilities that members of the peer review can abuse power to unfairly exclude privileges of potential competitors. In this sense, it is asserted in the U.S. antitrust lawsuits that the restraint of medical staff privilege can be the illegal restraint of trade in violation of section 1 of Sherman Act and can be monopolization or an attempt to monopoly by hospitals in violation of section 2 of Sherman Act. As Korea adopted open hospital system quite recently, there is still no case related with the exclusion of medical staff privileges. However, medical staff privilege system of Korea is not different from that of the United States in principle. Thus, the U.S. jurisprudence on the exclusion of medical staff privileges can be referred in the interpretation of "practice that interferes with or restricts the activities or contents of the business" based on Article 19.1.9 of Monopoly Regulation and Fair Trade Law of Korea.

  • This study shows the functional contribution into the public transportation system for congestion area. And there is a introduction for the rapid bus transit developed in Europe community. It can be classified the public transportation as urban transit, subway and bus. For a few years, it has been introduced the AGT system as a role of the alternative and lengthening system of subway line. Recently, there is going on construction of AGT system in some regional cities. The AGT system has advantages in terms of accessibility and cost-effective rather than subway. But the bus system is advantageous at the points rather than AGT system. It is obvious that the bus system is most cost-effective for infrastructure and system rather than any other public transports. If the bus system has punctuality and precise docking, that becomes best choice for public transportation scheme. There are tries to develop new systems by means of the f1les up the advantages in bus and AGT system, which can be classified as BRT(Bus Rapid Transit}. The idea is simple; 'Thirik rail, use advanced buses.' It is introduced the IRISBUS system at this article, which was developed in Europe community. And it is introduced the project architecture to develop the similar system to IRISBUS in KRRI through National Transportation Key Technology R&D Project

  • International factoring is very useful to transfer credit risk, to promote cash flow, to collect debt and to reduce cost and expenses. However, International factoring system in china shows imperfection especially in gap of legal vacuum and its limit to be developed. Here I suggest a practical alternative for development of International factoring system in china as follow. First, legal environment in China for factoring system should be rearranged. Even law and contract law have relative clauses for factoring system there are many difficulty to be applied. It is necessary to prepare legal ground for factoring system. Second, without recourse for International factoring system should be fixed. Without recourse is the essential point for factoring system in international trade. In fact chinese factors are partially applied only for those big global companies. However International factoring system is especially useful for small-medium companies lacked of a good credit rating. It is necessary to promote special factors by combining financial organizations as it does in developed countries. Third, they need to make legal ground to prohibit unlicensed factoring companies. Forth, they need to educate usefulness of factoring system. The settlement system in China is to be developed by systematic researches and promotion for International factoring system.

  • A review on the papers published in the Korean Journal of Air-Conditioning and Refrigerating Engineering in 2002 and 2003 has been carried out. Focus has been put on current status of research in the aspect of heating, cooling, air-conditioning, ventilation, sanitation and building environment/design. The conclusions are as follows. (1) Most of fundamental studies on fluid flow were related with heat transportation in diverse facilities. Drop formation and rivulet flow on solid surfaces were interesting topics related with condensation augmentation. Research on micro environment considering flow, heat transfer, humidity was also interesting to promote comfortable living environment. It can be extended considering biological aspects. Development of fans and blowers of high performance and low noise were continuing research topics. Well developed CFD technologies were widely applied for analysis and design of various facilities and their systems. (2) Heat transfer characteristics of enhanced finned tube heat exchangers and heat sinks were extensively investigated. Experimental studies on the boiling heat transfer, vortex generators, fluidized bed heat exchangers, and frosting and defrosting characteristics were also conducted. In addition, the numerical simulations on various heat exchangers were performed and reported to show heat transfer characteristics and performance of the heat exchanger. (3) A review of the recent studies shows that the performance analysis of heat pump have been made by various simulations and experiments. Progresses have been made specifically on the multi-type heat pump systems and other heat pump systems in which exhaust energy is utilized. The performance characteristics of heat pipe have been studied numerically and experimentally, which proves the validity of the developed simulation programs. The effect of various factors on the heat pipe performance has also been examined. Studies of the ice storage system have been focused on the operational characteristics of the system and on the basics of thermal storage materials. Researches into the phase change have been carried out steadily. Several papers deal with the cycle analysis of a few thermodynamic systems which are very useful in the field of air-conditioning and refrigeration. (4) Recent studies on refrigeration and air-conditioning systems have focused on the system performance and efficiency enhancement when new alternative refrigerants are applied. Heat transfer characteristics during evaporation and condensation are investigated for several tube shapes and new alternative refrigerants including natural refrigerants. Efficiency of various compressors and performance of new expansion devices are also dealt with for better design of refrigeration/air conditioning system. In addition to the studies related with thermophysical properties of refrigerant mixtures, studies on new refrigerants are also carried out. It should be noted that the researches on two-phase flow are constantly carried out. (5) A review of the recent studies on absorption refrigeration system indicates that heat and mass transfer enhancement is the key factor in improving the system performance. Various experiments have been carried out and diverse simulation models have been presented. Study on the small scale absorption refrigeration system draws a new attention. Cooling tower was also the research object in the respect of enhancement its efficiency, and performance analysis and optimization was carried out. (6) Based on a review of recent studies on indoor thermal environment and building service systems, it is noticed that research issues have mainly focused on several innovative systems such as personal environmental modules, air-barrier type perimeterless system with UFAC, radiant floor cooling system, etc. New approaches are highlighted for improving indoor environmental conditions and minimizing energy consumption, various activities of building energy management and cost-benefit analysis for economic evaluation.

  • Since 1990s, the use of Complementary and Alternative Medicine(CAM) has been rising rapidly all of the world. In 1983, WHO recommended that the traditional medicine actively be utilized. At the end of 20th century, as chronic and intractable diseases increased in western countries, traditional medicine has attracted considerable attention. COWM shows possibilities of new approaches for these intractable diseases. Thus, we try to show our proper approach of COWM through the international comparative study. In order to fulfill the objectives, we applied the following methodology: 1) Literature review on previous study, 2) Local survey using self-administered questionnaire, and 3) FGI(Focus Group Interview) with local experts. The results were as follows : Three Asian countries, China, Korea and Taiwan, are very active in implementing COWM policy. Japan, however, has independent system of unified medicine. In regards to the combined care policy and system, China has the most advanced COWM system among four countries. In respect to combined care education, it is needed to increase the COWM education contents and the amount of cross educational curriculum. Based on the current COWM system, Chinese, Japanese and Taiwanese doctors can prescribe both oriental and western drugs. But, Korean medical law prohibits western doctors and oriental doctors from prescribing the counterpart´s medicine. So, the revision of current medical law is urgent for COWM in Korea. And when it comes to patient satisfaction, more than fifty percent responded positively in China, Korea and Taiwan. To achieve the goal of COWM ; 1) mutual understanding and recognition of COWM is essential. 2) institutional and legal support system for COWM is desperately urgent. 3) possible international collaboration and cooperation should be sought to untangle these complex cultural dilemmas.

  • Public concern on the methods of raising food-producing animals has increased, especially in the last two decades, leading to voluntary and mandated changes in the animal production methods. The primary objective of these changes is to improve the welfare of farm animals. The use of gestational stalls is currently a major welfare issue in swine production. Several studies assessed the welfare of alternative housing systems for gestating sows. A comparative study was performed with gestating sows housed in either individual stalls or in groups in a pen with an electronic sow feeder. This review assessed the welfare of each housing system using physiological, behavioral, and reproductive performance criteria. The current review identified clear advantages and disadvantages of each housing system. Individual stall housing allowed each sow to be given an individually tailored diet without competition, but the sows had behavioral restrictions and showed stereotypical behaviors (e.g., bar biting, nosing, palate grinding, etc.). Group-housed sows had increased opportunities to display such behavior (e.g., ability to move around and social interactions); however, a higher prevalence of aggressive behavior, especially first mixing in static group type, caused a negative impact on longevity (more body lesions, scratch and bite injuries, and lameness, especially in subordinate sows). Conclusively, a more segmented and diversified welfare assessment could be beneficial for a precise evaluation of each housing system for sows. Further efforts should be made to reduce aggression-driven injuries and design housing systems (feeding regimen, floor, bedding, etc.) to improve the welfare of group-housed sows.
