Objective : The study was for researching the activation methods about Korean overall medical crops business from 2010 to 2016. In addition, it was to be given to examining complement points and improving methods to the changeable domestic market of medical crops caused by a considerable export-import amount of them. Methods : By examining and analyzing data for the trend of medical crops production and their export-import trend from 2010 to 2015, I found it valuable to use it as the basic resources for researching the urgent problem of medical crops' business and its improvement. Results : 1. As surveying the trend of the domestic medical crops over the recent six years, I found that the export amount of them has drastically decreased, while the import amount has increased. And so, the prices of the domestic medical crops and their production are unstable. 2. By developing standardized medical crops which a trading counterpart country could prefer, we have to promote the export competitiveness. 3. We should reinforce an origin mark and geographical mark practice for domestic herbal materials and expand GMP. 4. We should prepare a standardization of herbal medicines by setting up an independent governmental department. Conclusion : 1. The government should present an appropriate supply-demand amount of the medical crops depending on the domestic needs and the export-import transactions. 2. There should be an institutional supportive system which is able to guarantee stable incomes of farmers through contract cultivation. 3. We should develop high value standardized medical crops.

To realize process-driven management, so many companies have been launching business process managementsystems. Business process is collection of standardized and structured tasks inducing value creation of acompany. Moreover, it is recognized as one of significant intangible business assets to achieve competitiveadvantages. This research introduces a novel approach of workflow process analysis, which has more and moresignificance as process-aware information systems are spreading widely into a lot of companies, In this paper, amethodology of workflow clustering based on process similarity has been proposed. The purpose of workflowclustering is to analyze accumulated process definitions in order to assist design of new processes andimprovement of existing ones. The proposed methodology exploits measures of structural similarity of workflowprocesses.The methodology has been experimented with synthetic process models for illustrating the implicationofworkflow clustering.

The EDI system supports the working environment which can exchange the standardized document through the each agreed communication method. Traditional EDI system is complicated to be implemented and needed high cost te using the system because of the specific VAN(Value Added Network). This Paper proposes the XML/EDI system using the web-based distributed object and proposed the component 'AnySchema', as it makes be able to use legacy Database for EDI user. This XML/EDI system exchanges the XML documents through the Internet, so proposed low cost to support the system. Also, by using the XML document, it doesn't need EDI specific software and easy to exchange data between different systems. This system is implemented by using Java, as platform-independent.

This paper proposes a portable cable fault detection system with automatic fault distinction and distance measurement using time-frequency correlation and reference signal elimination method and automatic fault classification algorithm in order to have more accurate fault determination and location detection than conventional time domain refelectometry (TDR) system despite increased signal attenuation due to the long distance to cable fault location. The performance of the developed system method was validated via an experiment in the test field constructed for the standardized performance test of power cable fault location equipments. The performance evaluation showed that accuracy of the developed system is less than 1.34%. Also, an error of automatic fault type and location by detection of phase and peak value through elimination of the reference signal and normalization of correlation coefficient and automatic fault classification algorithm not occurred.

UBV photometric monitoring of Eps Aurigae has been made at Yonsei University Observatory since the 1982-1984 eclipse. Among observatios made in four seasons(1984-5, 1985-6, 1986-7, 1987-8) after the 1982-84 eclips ended the observations of the latest season are presented. Standardized UBV light curves of Eps Aur exhibit a light variation in a semi-regular fashion with the amplitudes of 0.12, 0.19, and 0.29 for V, B, and U, respectively. Duratiohs of this light variation may show a color dependency with the mean value of about 78 days whose minimum light on near JD2447118.

In today's building industry the emphasis has been geared more towards construction, thus building maintenance and life cycle have been neglected until now. A direct result of this neglect is the rapid aging of building, which leads to more cost-effective decision making methods for the prolongation of building life span. The following study is conducted in the area of Daegu and Seoul in order to develop the estimation analysis method of the annual operation cost of the Korean high-rise condominiums for the cost-effective decision making support through mathematical and statistical analyses including the present value and standardized measurement corrections. Based on the assumption that the life expectancy of the high rise condominium is 50 years, initial cost is ￦421,212/$m^2$, and a total sum of yearly operation cost during life expectancy is ￦2,154,499//$m^2$), yearly accumulated operation cost is shown as below: $AOC=0.7097t^4-38.803t^3+806.95t^2+11045t-496.52$ ($R^2=0.98$) (Here, AOC = Accumulated Operation Cost, t = given years)

In this study, the back analysis was performed by means of stereo-net, plane failure and block failure method to collapsed fields among the rock slopes designed by standardized criterion, and the internal frictions from the back analysis were compared with those used to reinforcement design. It was concluded that in the result of the analysis by means of stereo net, plain failure and block failure methods, the internal frictions used to re-design of collapsed slope underestimated 10$^{\circ}$, 5$^{\circ}$ and 10$^{\circ}$ in average. At present, the internal friction on the design is used the experience value according to the state of weathering, but internal friction angle by the back analysis on collapsed slope with various methods were more reliable values than those from the present method. And it was concluded that re-design was made extravagantly because the internal friction used to re-design for reinforcement of the collapsed slope was less than back analysis.

Additive Manufacturing defines the fabrication of objects by successive consolidation of materials, layer by layer, according to a three-dimensional design. The numerous technologies available today were recently standardized into seven categories based on the general method. Each technology has its own set of advantages and limitations. Though it very much depends on the field of application, major assets of additive manufacturing compared to conventional processing routes are the ability to readily offer complexity (in terms of intricate shape and customization) and significant reduction of waste. On the other hand, additive manufacturing often suffers of relatively low production rates. Anyhow, additive manufacturing technologies is being given outstanding attention. In particular, metal additive manufacturing emerges as of great significance in industries like aerospace, automotive and tooling. The trend progresses toward full production of high value finished products.

This paper proposes a multiple switch mode power supply (SMPS) system based on the wireless network which controls variable load. The system enables power supply of up to 600W using 200W SMPS as a unit module and provides a controlling function of output power based on variable load and a monitoring function based on wireless network. The controlling function for output power measures the variation of output power and facilitates efficient power supply by controlling output power based on the measured variation value. The monitoring function guarantees a stable power supply by observing the multiple SMPS system in real time via wireless network. The performance of the proposed system was examined by various experiments. In addition, it was verified through standardized test of Korea Testing Certification. The results were given and discussed.

This paper starts with the assumption that in order for hanbok to be made known to the world as a cultural code representing Korean beauty, it must first be made familiar among Koreans with opportunities for widespread use of hanbok in a way which forms an understanding with the fashion sense of young generations, and that wearing hanbok must be promoted. We observe the contents and problems of past hanbok festivals and provide methods to promote the wearing of hanbok among the population, creating an occasion for mingling with various cultures in hanbok events which may be experienced by the general population, and developing hanbok as a tourist item and promoting the hanbok industry through standardized hanbok festivals. Globalization of hanbok most occur through a combination of related academic fields, division of roles in fields of expertise, and a scientific understanding of hanbok. The re-creating of traditional hanbok will allow for affirmation of Korean image, a rediscovery of the value of Korean culture, and the establishment of cultural identity. The development of such global designs will form a foundation for hallyu wave culture within popular culture.
