We explore the determinants of long-term relationship between the buyer and the supplier to help suppliers develope a strategy to build long-term relationship with their buyers. Based upon an extensive literature review, we propose three droops of independent variables which may affect long-term relationship, including (a) environmental factors (product complexity, product importance, source dependence, price sensitivity), (b) relational factors(trust, commitment, satisfaction, intention of expansion), (c) operational performance(quality, delivery, cost capability, technical knowhow). The buyer's actual period of relationship with its main supplier is used as a dependent variable. Using hierarchical multiple regression analysis, we empirically test hypotheses, analysing a sample of 290 manufacturing firms in the U.S. The statistical results indicate that the buyer's source dependence, price sensitivity and the supplier's commitment play a significant role in establishing long-term relationship between the buyer and the supplier. However, the supplier's cost capability and technical knowhow in operational performance negatively affect long-term relationship in contrast with our hypotheses. Due to this controversial result, we divide the sample group Into dual sourcing and multiple sourcing environments and reconduct regression analysis in a post hoc manner. The findings show that the supplier's cost capability and technical knowhow are negatively associated with the length of relationship only in the multiple sourcing environment. The results may confirm that both parties' opportunistic behavior is more salient in the multiple sourcing environment than in the single sourcing environment.

Phlegm is defined as the static fluid in excess in one or more parts of the body. It is not only a pathologic product but also a pathogen itself. However, as it says Phlegm is another title for the body fluid. phlegm can be physiological. In Hyungsang medicine. since the Hyungsang which an individual shows determines his or her illness. the principle to treat phlegm also varies according to the individual's Hyungsang. Thus, the author reviewed ‘Jisan’s Special Lectures for Clinicians’ and summarized the concepts and diagnostics of phlegm, and treatment and regimens by Hyungsang medicine. The concepts of phlegm : Phlegm is not only a pathologic product of disharmony of Jung(精), Ki(氣), Shin(神) and Hyul(血) but also a driving force to mature and transform these constituents. Phlegm is another designation for the Fluid. Phlegm can act as an alternative substance or buffering agent. If we describe our body as the habitat of worms. phlegm could be the inhabitant. Diagnostics of phlegm : The infraorbital areas have a dark-gray or blackish coloring. A man who is feminine or a woman who is masculine tends to develop phlegm. One of the major signs of phlegm is pain in Chungwan(中脘). The color of the skin does not change. Treatment of phlegm by Hyungsang medicine. For the Jung type(精科) and the Hyul type(血科), phlegm treatment is to supply Jung and Blood or eliminate Damp-phlegm. The man needs tonifying herbs and the woman needs herbs which promote the flow of Ki(氣). Children and the aged are. tegardless of the nature of disease, to be warmed and supplemented. For the heavy man. treatment is to supplement Ki and eliminate Damp; for the slim man. treatment is to supplement Yin(陰) and purge Heat.

To survive competitive global market, textile and fashion business incorporated Supply Chain Management strategy to make product and information flows fast and correct. Especially textile and fashion industry involves many complicated channels from up stream, middle stream, to down stream for delivering their production. Evaluating SCM performance is very critical to make better business profit model. Representative Scor model and BSC method are well fitted into textile and fashion business because of distributional complexity, non-financial factors to be considered, and innovative product characteristics. But there was little study to compare these two methods for textile and fashion business. Therefore, the purpose of this study was to investigate the Scor model and BSC method based upon review of literatures. The results of this study were as follows: Scor model had some strengths which were availability to apply for various industries due to standardized process, operation process emphasized, various customizable factors to compose for the company, and premise on SCM strategic execution. BSC method had some strengths which were the balance including financial and non-financial factors, qualitative analysis, and considering the goal and vision to convey organically from top to bottom of organization. The main differences between them were different scope to deal with performance estimating index from qualitative to quantitative analysis, the scope of human resources to manage, and possibility of performance comparison among companies.

Two trial products of monogranular compound fertilizer for red pepper under vinyl mulching cultivatin were made using the principal sources of urea, diammonium phosphate and muriate of potash in combination with fillers of treated human wastes (product I) and zeolite (Product II). A field experiment was carried out to evaluate their effects on red pepper and the results obtained were as follows. Red pepper plant growth and total red fruit yields in the trial products of one time basal application were better and higher than those of NPK split application of contrl plot. The increases of yield in the trial products might be due to steady supply of nutrients for the entire growing period. Therefore, one time basal dressing of a developed monogranular compound fertilizer for red pepper was applicable under vinyl mulching cultivation.

Traffic congestions in local cities have been getting worse since 1990s, so many local governments have considered the introduction of an LRT system. So far, there is no city operating the LRT due to social environments, financial reasons, feasibility and so on. But still many cities have examined LRT or started the construction. Until now, more than 30 cities are constructing LRT or planning the introduction of LRT and it becomes 96 routes, approximately 700km. With the support of MLTM, KRRI has developed automatic LRT system with rubber-wheels, K-AGT as a result of "LRT system technology development project" from 1999 to 2005 by investing 50.32 billion wons(the public 37, the private 13.32) and finished running durability test of 100,000km at Kyeong-san test line. Currently, two trains, coupled two cars respectively have running and signaling tested. K-AGT was appointed to supply for an extension line at Busan Subway Line 3(Minam-Anpyeong section) with 17 trains(six-unit car) 102 cars. However, except for Minam-Anpyeong section, other cities such as Uijeongbu, Yongin, Daegu(Line 3) and Kwangmyeong decided to use the foreign systems, not to use the product, a result of national R&D project. This results in a huge waste of foreign currency and it is expected to require much additional cost for maintenance. If local governments use the products of national R&D projects, many national benefits such as reducing imports and protecting home industries could be expected, therefore in this paper, some plans to encourage to use products of national R&D projects were dealt with.

In recent years, the need for more fuel-efficient and lower-emission vehicles has driven the technical development of alternative fuels such as LPi (Liquid phase LPG injection) which uses pump for the high pressure supply of liquid LPG fuel and is able to meet the limits of better emission levels while it has an advantage of higher power. Although it has the advantage of power and lower emission levels, the characteristics of LPG, such as high vapor pressure, lower viscosity and surface tension than gasoline fuels makes it difficult design system. Therefore most fuel pumps and injectors are imported. In the present study, in order to domestically develop LPG injector which guarantees flow rates and optimal operation, the experimental investigation on leakage and flow rate characteristics of developed prototype injector was carried out at the bench test rig for developed injector.
