This study suggests the dynamic pricing model which reveals the organic relationship between ASP (Application Service Provider) price and the related factors, using system dynamics methodology. Basically, we applied the law of supply and demand for analyzing price changes. Then, we deducted ASP price, focusing on fixed cost and variable cost. We also researched the customer's buying behavior according to version differentiation policy. In the version policy, we set up the proposition about customer's satisfaction and willingness-to-pay, using option system. As a result, this research designed the simulation model which analyzes the changes of the sales according to version differentiations and customer's willingness-to-pay. Through this research, we can find effective version differentiation strategies. This paper also found that the larger the number of package, the greater the demand and customer's willingness-to-pay. The increase of the number of package causes the increase of the sales. The increase of the sale is not exactly relative to the number of package. Drawing S-curve, the sales was increased. This dynamic pricing model suggests the ground that the ASP price changes based on the existing version differentiation theory and the demand of customers can affect the changes of the sales. We expect that this model suggests a clear standard of ASP pricing by combining real cases.

The reliability of BGA (ball grid array) package with OSP (organic surface preservative) surface finish under thermal cycle was investigated by using SEM (scanning electron microscopy), EDS(energy dispersive spectroscopy), image tool and ball shear test. The IMCs (intermetallic compounds) were increased with increasing number of thermal cycles. However, the shear strengths of solder ball were decreased with increasing number of thermal cycles. The order of solders which had the highest shear strength as follow: Sn-3.5wt%Ag-0.7wt%Cu, Sn-0.7wt%Cu, Sn-37wt%Pb.

Before the ultra-violet glue encapsulation, the research evaporated LiF thin film on device surface to be the extra packaging layer for improving the lifetime of organic light-emitting diode. The formula of UV glue was specially developed. We found 100 nm LiF is the optimum thickness. The best lifetime obtained by using LiF and special UV glue is 2.4 times longer than those by commercial UV glue.

This study analyze the willingness to pay for customized agricultural products to diabetes. For this purpose, a survey was carried out for patients with diabetes 212 patients. The main results are as follows. First, the survey found that the interest in health and food was found to be very high in 93.9 % and 85.9 % respectively. This means that there is sufficient market potential if customized food and diets for diabetes are developed. Second, the Logit analysis showed that influential factor for the willingness to pay for a customized diet. The higher the risk, the better the health outcomes, the higher the likelihood that the higher the level of income, the more likely it is to purchase a product for a diabetic food package. Third, the average amount of willingness to pay for the customized food for diabetes patients was 7,823.5 won and the truncated average value was 6,953.3 won.

The objectives of this study were to find out determinant attributes of selecting Environment-Friendly Agricultural Products (EFAP) and to analyze the degree of consumer's satisfaction by using factor analysis. To identify determinant attributes of EFAP, a series of household surveys were conducted on housewives residing in Seoul. The sample size of the survey is 247 respectively. The main results of this study are summarized as follows. Firstly, the degree of consumer's satisfaction and loyalty is higher than before. Secondly, the consumers recognized that the most important attributes in selecting EFAP is a 'taste'. Thirdly, 'price policy', 'diversity of purchasing items' and 'package design' will continuously speed up the development of EFAP in order to improve the consumer's satisfaction.

We have designed and synthesized the colorimetric chemosensor through the reactions of 1,2-anthraquinone and indol-3-carboxaldehyde. Due to its well conjugated D-${\pi}$-A system and the existence of NH-fragment in indole moiety, we expected that the chemosensor can detect target anions with NH-fragment in indole part of the structure. In this regard, UV-Vis absorption spectra were measured to investigate sensing properties of the probe toward different anions in DMSO. This chemosensor shows to detect fluoride anions with absorption change in intensity. These properties are mainly related to the deprotonation effect. ICT system in this molecule was also observed by the computational approach using Material Studio 4.3 package.

In this study, pyrene based chemosensor was synthesized by two step reaction. The chemosensor showed that high selectivity toward fluoride in DMSO. The fluorescence intensity was drastically increased by binding between chemosensor and fluoride ion. Absorption and fluorescence spectra were obtained by UV-Vis spectrometer and fluorescence spectrophotometer. The binding ratio between chemosensor and fluoride ion was also investigated by job's plot method and Benesi-Hildebrand plot. The HOMO/LUMO energy levels and electron distribution were calculated and simulated by Material studio 6.0 Package.

The objective of the study to investigate factors affecting consumers' consumption extension toward environment-friendly agricultural products in Suncheon city. The main results of the analysis are as follows. First, the main reason that consumers purchase environment-friendly agricultural products is "concerns of pesticides." Second, NAQS is highly trusted of a certificate institution. Third, the results show that consumers is satisfied such as safety, freshness, nutrition, whereas price, package design and taste are dissatisfied. Fourth, the factors affecting increase in the consumption of environmental-friendly agricultural products, have been analyzed in the variables noted of whether Sex, marital status, purchase experience, Private Certificate Authority faulty.

The alternative marketing can be defined a face to face regional marketing that commodities are traded based on mutual trust and understanding which have been accumulated through relationships formation and interaction between producers and consumers. Essences of an alternative marketing are formation, expansion and solidarity of relationships between producers and consumers, mutual trust and communication, and cooperation. Based on these, it makes it's principle to trade regionally and shorten food mileage and psycho-social distance. For example, there are local food direct stores, local food markets, farmer's markets, food package sales, CSA, local food school or public meal and so on. In alternative marketing, the relationship among them is especially considered very important in marketing process, not just a flow of commodities.
