This article is to develop test product as adopting motifs from Andong Hahoe Village registered in the UNESCO World Heritage. This study associates physiographic features and images of Hahoe Village with test product. In the research result of this study, the value of product and possibility of success of test product was found as follows. Firstly, Making the puzzle-oriented Desk Service Hahoe Village views by using 22 different styles & functional artworks. Secondly, Producing the tangible forms such as a tree, thatched cottage, arbor, tile-roofed house and ferryboat by casting technique. Thirdly, Designing the shape of the terrain by utilizing computer programing softwares such as CAD drawings and ARTCAM. Finally, Developing the mass-produce goods reflecting region historical and cultural characteristics. I expect this study may increase of interest of our country's culture and play several roles of the bridgehead for product development. Also I reconsider sensitivity recovery of users and our cultural value increase.

The genus Vibrio contains some of the most important intestinal pathogens of humans, including Vibrio cholerae, the cause of epidemic Asiatic cholera. A group of organisms which have been reffered to as the non-agglutinating vibrio (NAG) do not agglutinate in the Vibrio cholerae 0 group 1 antisera, but are indistinguishable from the 0-1 group both chemically and genetically. Non-O-l Vibrio cholerae can cause isolated as well as focal outbreaks of diarrhea, but the volume of fluid loss does not approach that of classic cholera, and the disease is usually self-limiting. These free-living organisms are found world-widely distributed in the environment including sewage, contaminated water, estuaries, seafood and animals. These strains involved in several cases were isolated from the environment and some patients of diarrhea, and a few epidemiologic reports indicated the wide distribution of the strains throughout the country, giving an attention to the role the organisms may play in an outbreak of diarrhea in Korea. More research on the epidemiology, serologic typing and virulence of the group of organisms, should be, therefore, done to obtain a complete understanding of their role in human disease.

Recycled pulp therefore play a very important role in the paper industry today as a substitute for virgin pulp. In many countries of the world, the paper industry could not exist as it does without recycled pulp. Because, this is mainly due to economic reasons. Particularly in our country, the additional reason is the scarcity of native pulpwood resources. Therefore, the use of recycled pulp is very important. This study was aimed to apply recycled pulp to textbook paper. So we made a paper containing 30% recycled pulp and investigated about print quality, such as color reproduction, trapping, contrast, dot gain, gloss and print through. The results showed that is similar to existing textbook papers.

Collision is a brief dynamic event consisting of the close approach of two or more objects or particles resulting in an abrupt change of momentum or exchange of energy because of interaction. Collisions play very important role in computer graphics, computer games and animations fields. Collisions can supply active interaction between cyberspace and real world and give much interests for making nice games so reasonable collision detection algorithms are needed. Collision detection algorithms should satisfy being fast and accuracy. In this paper, we survey the 2D collision detection algorithms between geometric models. We present several methods and system available for collision detection.

Italian furniture companies play a leading role in the world furniture market and are acknowledged as good design trend leader. Their craftsmanship which has been handed down from the past is thoroughly applied to the process of design and production. Two well-known furniture companies in Italy, 'B&B Italia' and 'Kartell', are chosen as a case study model to grasp the key of their success. In general and objective material collecting and researching, this study aims at understanding the method of the advanced corporations' design development, marketing strategy and brand identity This study is expected to use as a research material for Korean furniture industry to escape from the serious depression after IMF shock.

Renewable energy resources play an important part in the world's future. Renewable energy sources have the following components: biomass, geothermal, solar thermal, directs solar, wind, tidal and hydropower. Hydropower is still the most efficient way to generate electricity worldwide. Hydropower projects can contribute as a cheap energy source, as well to encourage the development of small industries across a wide range of new technology; furthermore hydropower systems use the energy in flowing and falling water to produce electricity or mechanical energy. Hydropower systems are classified as large, medium, small, mini and micro according to their installed power generation capacity, as do the following components: water turbines, control mechanisms and electrical transmissions. In this article a review of small hydropower systems has been done on the principles surrounding the fundamentals of hydraulic engineering, the fundamentals of hydrology, identification of sites and economic analysis.

Since discovery, NdFeB permanent magnet has replaced application of the conventional magnets rapidly because of its superior physical and mechanical properties. With increasing consumption of power combined with energy resource depletion, energy efficiency is becoming more and more inportant. According to recent reports, almost almost half of the electric power is consumed by motor, and NdFeB magnets which are the core component of the motor play a key role on improving energy efficiency of the devices. In parallel with finding alternatives energy resources, research works improving energy efficiecy have been conducted world wide. Althogh NdFeB magnets usage have been expanded to various applications, key materials such as Nd and Dy, resouces lean heavily on specific area, China. Magnetic industry revently experienced skyrocketing price fluctuatioin of rare earth at around 2008. Chineses government's regulations worsened the situation and arose a necessity to develop methods to minimize rare earth use. In this presentation, POSCO's recent research works on rare earth reduction is presented including novel powder alloying method using nitrate precursors. Also, future R&D plans for rare earth free magnets is briefly introduced as well.

The specific purpose of this was to investigate if ir was feasible to design and execute garments that were multi-functional in purpose for women living in an expended world of social and occupational interaction which rerequired flexibility and convenience in their clothing appropriate to their multiple roles in society. The study was to carry out based on the selected situations(business situation-social situation and private situation-social situation) and designs deduced from the situations. The garments could permit flexibility in style through adjustable features which could be attached to, or detached from, the garment depending on the occasion and need of the wearer. As the results of the study, the characteristics of multi-functional garments were found as follows : First, the garments could bring about flexibility in garment formation through adjustable details, overlay and patch, in order to increase the multi-functional usage of the garments. Second, the style of garments could be expressed design images to meet the needs of flexibility and convenience for the various occassions. Third, the multi-functional garments could meet the needs for time and economic values for the women who play multple roles.

According to globalization of world economy on distribution and sales, logistics and transportation parts are play important role. Especially, it important to know and study how to choose right transport route and which is the key factor of route choice model in multimodal transport system. Thus this study aims to consider 4 main factors: cost, delivery time, freight, and logistics service factors additionally dividing into 13 sub factors and object is forwarders between Mongolia and Korean freight transport. The survey is based on AHP through interview with company officials. The paper provides empirical insights about current status of Mongolian forwarders and difference of the important factors between transportation modes. Result shows that time factor is role factor to choose transport route and then cost factors. Additionally, this study shows 2 different route choose factors between air transport and shipping transport forwarders.
