In injection molding industries, CAE analyses are generally used to find out problems predicted during the process of manufacturing. The results of CAE analyses consist of much in formation such as meshes and stress, so that the size of data is pretty large. To reduce the size of the data and to make it easy to share, the CAE result to JT translator is proposed in this paper. The translator consists of three modules to translate CAE result to JT format; Extracting module gets ASCII data of product shape and the result values of CAE analysis. Sorting module and mapping module make an element data set and JT file with the data extracted from Extracting module respectively. To the JT files, engineers are able to append product properties and their comments, so that they can share the whole history of the analysis process. In addition, our case study shows that the size of JT format is reduced by almost 90% of its original data format.

Data Security is the most challenging area in Internet communication, where most of the secret sharing schemes are proposed for binary images. But still it lacks in providing security for data communication, especially in image transmission. Traditional visual cryptography scheme generate meaningless diwies and the reconstruction phase leads to quality degradation over the secret image. In this work, an intelligent two dimensional secret share construction scheme is proposed. A secret image is expanded into n diwies with the choice of scheme selection. By Stacking all the qualified diwies to revert the secret image without content loss and less than s^* - 1 shares could not reveal any information about the secret image. The experimental results emphasize that the proposed secret share scheme is highly secured for image transmission.

Materials Industry has a very large ripple effect on national economic development. Nevertheless, Korea has been passing over importance of this Industry. So, this study examined competitiveness on ten chief exporting items to U.S.A market based on the understanding of vital role of materials industry in the national economy. Analyzing methods were Market Share, Trade Specialization Index(TSI), and Market Comparative Advantage(MCA) and the data were collected through parts and materials statistical data which produced by Korean Commerce and Industry Minister. From this study, following results were found. i) Highly ranked items of U.S.A market share were chemical fiber drapery weaving, synthetic fiber. These items commanded over 10% share of the same market and tire, steel wire occupied 9.05%, 8.65% respectively. ii) In searching trade balance aspects through TSI, tire and steel wire secured very powerful competitiveness among examined items in trading with U.S.A. while synthetic resins and other plastic material were very weak competitiveness in the same market. iii) Analysis results of market competitiveness by MCA, indicated that chemical fiber drapery weaving, synthetic fiber and tire ensured high-powered competitiveness in U.S.A Market. Therefore, these items would be positioned as main items in the market.

This study was performed to investigate the practical oriental medical expenses by the use of internal data of an oriental hospital due to the bias of medical insurance program data. The purpose of this study was to describe prevalent diseases of clinical department in the studied hospital, to analyze medical expenses structure and to verify the each cost share ration of expenses on insurer to insuree. Under this purpose, we analyzed actual medical expenses data of 1,611 hospitalized patients of the oriental medical university hospital with 150 beds that can be approached to internal data from Jan. 1, 1994 to Dec. 31, 1994. The major findings are as follows : 1. Upper five of most frequent diseases of admitted patients were Joul-Jung-Pung(55.5%), Yoo-Kak-Tong(7.3%), Yoo-/Tong(7.1%), Gu-An-Wa-Sa(2.7%) and sequale of Joul- Jung-Pung(2.4%) 2. In medical expenses structure, hospital ward fee was 47.1%, medication fee 41.3%, fee for procedure(acupuncture, moxibustion, negative therapy, physical therapy, etc) 11.1% and consultation fee 0.5%. In addition to the cost share ration of insuree & that of insurer was 75:25 respectly.

Development of IT technology, in combination with the medical area, a number of developments have been made of the digital advanced medical devices, also increased interest in health, sharing of medical information has become increasingly necessary. Standardization for medical information sharing to satisfy these requirements have been studied. However, the medical information system is to build a system independent hospital itself, is difficult to share and exchange medical data with other medical institutions. In this paper, we provide a medical cloud system that can share medical information. Use DBaaS of cloud services. And is an international standard to have a HL7 share information by forming a meta-schema, each of the data transfer, the format of the document oriented data solves the heterogeneity between hospitals. Extracts the required field name of examination information, to exchange information with each of the local information and mapping. Health diagnostic information in the present study and diagnosis through accurate information sharing and exchange is possible ongoing management.

In this paper, we propose an efficient friendly forces location data sharing algorithm in a troops using a low bandwidth radio. The future battlefield is a 'Network Centric Warfare' with a concept of identifying the position and power of the enemy and friendly forces and leading the battlefield to victory through proper links at the time of our need. One of the basic elements in the 'Network Centric Warfare' is to share friendly forces location data. The bandwidth and transmission rates of radio used in battalion are low. Nevertheless, we should share our locations data almost in real time for effective fighting in a war situation. This paper describes the efficient method of friendly forces location data sharing based on low bandwidth radio. In particular, the concept of 'network-centered warfare' is reflected in the troop below the battalion to present an integrated and efficient way to shared location data of friendly forces.

This paper empirically analyzes the influence of export insurance on export promotion using panel data for the Korean case during the sample period from 2003 to 2006. We use the Korean export's share in trading partners' imports as a weight for the weighted least square (WLS) estimation to measure the effect of export insurance on the export promotion. Our main finding is that export insurance subsidy seems to enhance the export performance when the Korean export takes greater share in other countries' markets. On the other hand, under weaker monopoly power of the Korean export, export risk and trading partners' GDP growth rate has more influence on the export promotion rather than export insurance subsidy. Our finding implies that policy makers and practitioners should discern the Korean exports' monopoly power differential across trading countries for better performing export insuarnce policy.

Purpose - This study undertakes to examine the automotive trade structure between Korea and Russia to accelerate economic cooperation and pinpoint trade discrepancies to increase trade volume through improved policies, eventually finding ways for trade expansion. Research design, data, and methodology - To analyze trade decision factors for both countries, the Index of trade specialization invented by trade specialization theory, is used. Although specific factors should materialize in the trade decision analysis, realistically, concrete explanations are difficult as many unsolved factors are involved as well as their complexities Results - First, to assess comparative market competitiveness, the Index describes A value/B value, representing the Korean versus the Russia market share and the Korean market share versus the world. Second, the index shows that Korea is taking comparative advantage of its export specialization. Third, the RCA indices show considerable improvement compared to 2000. Conclusions - This research used a quantitative approach to examine trade specialization and examined a comparative advantage index of market share to see how inter-trade relations have changed over the past 10 years.
