The direct and indirect PFBEM(power flow boundary element method) for the treatment of the 3 dimensional multi-domain problems are proposed to predict the acoustic energy density in medium to high frequency ranges. In the proposed method, the equation is derived in a matrix form by considering coupled relationships of the power flow at the interface of given domains. The proposed method can successfully obtain the analytical solutions for the problems of coupled cubes and the small-scale reverberant chamber. Then the experiment is carried out to obtain STL(sound transmission loss) by using small-scale reverberant chamber and the results are compared with analysis results.

The KEPRI has been developing the medium/small scale Distribution Automation System(DAS) that adopts wireless transmission media for exchanging information between master and remote terminals. It was concluded that Short Message Service(SMS) of Personal Communication Service(PCS) was the best wireless transmission media for the medium/small scale DAS in the last year. However. we had problem that PCS had long transmission delay. Therefore. SMS phones will be substituted with Radio Link Protocol(RLP) modems having transmission delay less than 5 seconds. This paper describes wireless networks for DAS, practical experience.

We developed the training simulator for KEPCO operators to maintain small-scale distribution automation system effectively. The training simulator has the same screen form and operating environments in comparison with using system in field. It is to be wished that the operating techniques of KEPCO operators will progress to solve the fear of system operation and to training simulations of distribution conditions again and again.

The main purpose of this study is to examine agricultural technologies through plowing and hoeing. One of the purposes on which this study is to analysis process of development and divergence of plough and hoe. The following facts are significant findings ; 1. In early Yi - dynasty, tilling implements used by ard plough and mould board plough did use in three south province, most region mainly used ard plough. Therefore, farming in early Yi - dynasty is extensive. 2. The mould board plough diffused in many fann house, spring farming and autumnfarming formed complet system in early 17th Century. But works of hoeing was continuing to save labor by long hand hoe. 3. Finally in 17th century, Small - scale independent farming ceaselessly tried to make his basis with transtortation intensive farming method. But Small - scale independent farming had not stafely base because extensive farming method continued in this peorid.

This paper Proposes the individual roles for developing small web application systems based on the Client/Server architecture with the activities and artifacts of each role and cooperation. The roles of Web Server part (i.e. User Interface Designer, Web Designer, HTML Writer), the roles of Application Server part (i.e. Domain Expert, Application Developer, Tester) and the roles of DB Server part (i.e. Database Administrator, Data Designer) are described. Furthermore, the role of the Development Leader that participates in development and manages all works in project and finds the solutions of problems in project, is also discussed. The Domain Expert analyzes the domain of the application in order to send the artifacts to the Application Developer. Then the Application Developer analyzes, designs and implements the application based on the artifacts of the Domain Expert and integrates the implemented program modules. Roles are related each other in this way, and cooperate until the application development is completed. Finally, we analyzed and compared these roles with the roles of RUP(Rational Unified process) and web wave. Suggested roles in this paper turned out to be efficient compared to the roles of the existing large-scale methodology.

Purpose: To review the Scale Measurement studies on Traditional Chinese Medicine and it's prospection. Method: The papers reviewed in this study were searched through internet search engines such as China National Knowledge Infrastructure(www.cnki.net). we searched papers on Scale studies by the keyword "量表"(Scale) and "中醫"(TCM). Results: 263 papers which is truly related on "Scale" were collected. All the papers were reviewed briefly under the subtitle of diagnosis, evaluation of curative value, development of scale, reverse of overseas questionnaire to chinese literature and etc. Conclusions: Scale measurement studies on TCM proceeded so much but their medical application was on small and narrow field. Also Scale study had TCM's characteristics were only 18% of them. Neverthless, productions from China were precious and valuable to Korean Oriental Medicine and we have to learn their success on scale measurement studies.

In recent years, environments of business are changing due to epoch-making development of information technology and the advent of digital economy ages. It is an active confrontation as to the environments for information. Unlike the large scale enterprises in those days, hower, many small & medium enterprises especially the enterprises which are engaged in the manufacturing industry-aren't participate in information's rank due to the lack of funds, manpower, insufficient management environments, and manager or staff's lack of cognition as to information. So, this paper make a base of establishment for ISP through the establishment of ERP that is used to management activity for small & medium manufacturing enterprises. A way for small & medium enterprises' ERP construction is SMERP S/W for the small & medium enterprises' ERP package which is offered by the Korea chamber of commerce & industry. And, that is applied to the real management environment.

This study aims at identifying the characteristics of various income earning activities conducted by small family farms, so-called pluriactivity, in Korea, Traditionally small farm households have been regarded in Korea as those who have not only very limited economic capability, but also very low status in rural society. However, in Europe, since the 1990s, there have been some researches found out the role of small farms in socio-economic development of rural regions. These tended to conclude that such various economic activities of small farms' may contribute to the development of rural region. Introducing the concept of pluriactivity from the European studies, this study carried out surveys and interviews with 38 small farm household in Chungnam region in terms of the fundamental reasons for pluriactivity and the impact on rural economies. The analysis revealed the main reason of pluriactivity could be the lack of income for family. Nevertheless, this study also identified another important reason of pluriactivity that small farms' desire to live in rural areas may drive them to do the pluriactivity. It may mean that farming could not be the main option for them to live in rural areas. In addition, it was confirmed that this pluriactivity has a positive impact on rural areas, such as landscape management, job creation, and cultural provision. Along with this, it was confirmed that there is a difference in pluriactivity characteristics according to age. It then necessary concludes that the rural development policy must consider the characteristics of farm households when they provide the support for farming and non-farming activities.

To improve the standardized quality of gochujang produced by major companies, the quality characteristics of 29 gochujang samples produced by regional small- and medium-scale manufacturers were determined. The average moisture content, crude protein content, pH, acidity, and salinity of gochujang from regional manufacturers were found to be 34.32-45.53%, 5.07-5.68%, 4.61-4.92, 3.30-3.72%, and 9.93-16.14%, respectively. The contents of reducing sugar, amino type N, and capsaicinoids were found to be 16.81-29.81%, 191.72-660.55 mg%, and 32.49-79.58 mg/kg, respectively, and the ${\alpha}$- and ${\beta}$-amylase activity were 2.52-4.15 and 26.36-36.47 U/g, respectively. These values varied significantly across regional manufacturers. In addition, overall, gochujang had a range of 23.93-55.64% moisture content, 4.01-7.30% crude protein content, 105.47-1092.00 mg% amino type N content, and 8.74-181.50 mg/kg capsaicinoid content. These results indicate that the quality characteristics of gochujang showed a wide distribution but met the Korean Industrial Standards. Therefore, these data can be used for quality control of gochujang.
