The purpose of this paper is to explore the strategy of future Korean medicine(KM) clinical research through the study on the current situation and issues for KM clinical research worldwide. In this study, the papers published in English through Pubmed were investigated mainly. And we analyzed the methodological issues from the clinical research reports in the KM fields. As a result of examining the current situation of the RCTs(Randomized Controlled Trials) studies in KM, the sample size for most studies was small and the overall methodological quality appeared to be low. And there was a discussion about whether or not to apply RCTs method to the KM clinical research. The majority of studies have argued the use of RCTs method for KM clinical research. In addition, we could find some problems through the analysis of KM clinical studies. First, the majority of RCTs in KM were of low quality. Second, RCTs method was applied to the KM clinical studies according to the Western medicine methods only. Third, the actual KM diagnosis was not used in the KM studies and inadequate outcomes measurement methods were utilized without considering the characteristics of KM practice. The methodological issues in the KM clinical research were caused by the conflict between the characteristics of KM practice and clinical research method based on the western medicine.

We developed a grid-based Gaussian plume model to evaluate tracer release data measured at Young Gwang nuclear site in 1996. Downwind distance was divided into every 10m from 0.1km to 20km, and crosswind distance was divided into every 10m centering released point from -5km to 5km. We determined dispersion factors, ${\sigma}_y\;and\;{\sigma}_z$ using Pasquill-Gifford method computed by atmospheric stability. Forecasting ability of the grid-based Gaussian plume model was better at the 3km away from the source than 8km. We confirmed that dispersion band must be modified if receptor is far away from the source, otherwise P-G method is not appropriate to compute diffusion distance and diffusion strength in case of growing distance. So, we developed an empirical equation using linear programming. An objective function was designed to minimize sum of the absolute value between observed and computed values. As a result of application of the modified dispersion equation, prediction ability was improved rather than P-G method.

This paper suggests a method for tuning a numerically simulated wind speed data, provided by NIMR(National Institute of Meteorological Research) and generated from a numerical meteorological model to improve a wind resource map with a $1Km{\times}1Km$ resolution. To this end, "tuning factor method" is developed that consists of two procedures. First, estimate monthly wind fields based on a suitably designed statistical wind field model that covers 345,682 regions obtained by $1Km{\times}1Km$ lattice sites in South Korea. The second procedure computes the tuning factor and then tunes the generated wind speeds of each month as well as each lattice site. The second procedure is based on the wind fields estimated by the first procedure. The performance of the suggested tuning method is demonstrated by using two wind data(both TMY and numerically simulated wind speed data) of 75 weather station areas.

Today, knowledge is considered the most strategically important resource. As research in knowledge management advances, it ought to review and categorize the already published literatures on knowledge management in the area of business strategy, accounting/finance, human resource management and management information technology. To identify the knowledge management research trend, we analyze 168 articles published in prominent academic journal during last two decades. This paper develops three stages model for knowledge management research: observation, initiation and evolution stage. Also, we classify the given researches according to the three criteria of contents, related academic area and applied research method.

Objective : This study aimed to compare the patients' satisfactions with local Korean Medicine(KM) clinics and networked KM clinics, and to find out which factors had an effect on it. Method : Six local KM clinics and six networked KM clinics were selected, and patients' questionnaires on the satisfaction with KM clinic use were administered using exit poll method. The questionnaires were developed to measure satisfactions with facility, doctor and staffs, and services. 240 patients completed the questionnaires, and the data were statistically analyzed. Results : There was more diversity in patients' diseases among networked KM clinics users, however, treatments provided were not differentiated clinically between two types of KM clinics. Patients' satisfaction scores for local KM clinics were significantly higher than those for networked KM clinics in the aspects of doctors/staffs (9.35 vs 8.92, p<.01) and services (8.76 vs 8.42, p<.05). 90.0% of local KM clinic users expressed their willingness to recommend the clinics they used to others, while 75.0% of networked KM clinics users did. For both the local and networked clinics, 'KM doctors' kindness', and 'process and waiting time' were statistical factors affecting patients' satisfaction. Conclusion : The patients' satisfactions with general KM clinics were higher than those with networked KM clinics. Networked KM clinics need to develop services to meet the diverse medical demands which were created by them selves.

배출량 산정방법 정의서(환경부, 2000)에서는 점오염원을 제외한 면오염원과 이동오염원에서 배출되는 대기오염물질의 공간할당은 개별 오염원의 배출량을 격자에 배분하여 합산하는 방식을 제시하고 있다. 이때 일반적으로 TM-좌표상에서 1km x 1km로 구성된 격자에 배출량을 할당하게 된다. 국가 전체로 보면 1km x 1km 격자계는 상세정보이지만 대부분의 대기영향평가의 대상범위는 국지규모이므로, 이 경우 1km x 1km 격자 할당방식으로 구성한 배출정보를 사용할 경우 부정확한 예측결과를 가져올 수 있다. (중략)

In order to extract the curcuminoid such as curcumin, demethoxycurcumin (DMC), and bisdemethoxycurcumin (BDMC) in turmeric (Curcuma longa), solvent extraction methods (dipping and ultrasonic extraction method) and solid-phase extraction (SPE) were used. RP-HPLC (reverse-phase high-performance liquid chromatography) and TLC (thin-layer chromatography) were used for identification and analysis the three curcuminoid. From the experimental results, it is evident that the percentage of curcuminoid extracted from turmeric by ultrasonic extraction method was higher than dipping method. The percentage of curcumin extracted from turmeric by pure methanol was higher than any aqueous methanolic composition. Moreover, the total peak area of three curcuminoid was above 92% in RP-HPLC using solid-phase extraction. These results will form a database for investigating the constituents of natural products and the resources of pharmaceutical, nutrition, and cosmetic products.

This paper examines whether the conceptual metaphor theory, which has been recently treated as important research topic in the field of cognitive linguistics, can be a new method that can promote the modernization of basic Korean medicine (KM) theory. In addition, the significance and potential of this study are reviewed by looking at Chinese research cases that applied this theory to Traditional Chinese Medicine theories and terminologies. The results are summarized as follows. From the viewpoint of metaphoric cognition, KM is a medicine that attempts to understand the human body (microcosm) through nature (great universe) by metaphorically projecting human experiences of nature on the human body based on the thought of correspondence between nature and human (天人相應). The language system of KM is based on a metaphor that extends our experience of nature to the human body, and an abundance of metaphors can be seen throughout the language of KM. Understanding and interpreting KM theories and terminologies from a metaphorical point of view allow us to understand the nature of KM theoretical key terms more deeply than now. And this understanding can help define and describe KM theoretical key terms and promote the modernization of KM theory research. In addition, various image schema that plays an important role in the metaphorical expansion of physical experience can be used for modeling KM theory. Research of KM theories and terminologies from a metaphorical point of view can serve as a bridge between traditional KM theory and modernization research, opening a new path to the modernization of basic KM theory in difficult situations.

Marine magnetic survey were carried out at Sokotra Basin offshore Korea between latitudes $31^{\circ}$ 42'32' N and $32^{\circ}$ 46'29' N, and longitudes $123^{\circ}$ 56'26" E and $125^{\circ}$ 49'16" E in order to estimate the depth of basement complex and as well as to configure it surface and produce the thickness of sedimentary sequence at the study area. Two methods have been used for depth estimation and basement configuration: the power spectrum and the 3-D analytical signal. The estimated depths resulted from the power spectrum method range from 1.4 km to 6.0 km for deep sources (basement troughs), and from 0.3 km to 1.75 km for shallow source (basement peaks). An isopach map was prepared for estimating the thickness of the sedimentary sequence at the study area; it ranges from 1.2 to 4.66 km. The estimated depths resulted from the analytic signal method range from 1.0 to 6 km. A basement configuration map was constructed for the study area in the basin. They show a well agreement with the geology of the study area.

As knowledge has been recognized as a new resource in gaining organizational competitiveness, Knowledge Management (KM) is suggested as a method to manage and apply knowledge for business management. KM research, however, has focused on identifying, storing, and distributing the transaction-related knowledge in an organization. There has been little research on applying the knowledge to decision-making or strategy development that is the main task of business management. The application of knowledge to decision making has higher impact on organizational performance rather than just the knowledge management for process transaction. In this research, we suggest System Dynamics (SD) for the knowledge-based decision-making. Based on the modeling method of SD, we can translate partial and implicit knowledge resident in individual's mental model into organized explicit knowledge. The simulation test of the organized knowledge model enables decision-makers to understand the structure of the target problem and its behavior mechanism, which facilitates effective decision-making. We will compare the proposed method and other KM methods and discuss this research based on the application case to a real telecommunication company.
