Consumer satisfaction/dissatisfaction is key determinant of brand loyalty and store patronage behavior. But the results of many customer satisfaction surveys implemented by department stores show that consumer satisfactions do not predict the actual patronage behaviors well. The main reason of these surprising results would be that the consumer satisfaction indexes do not include some important determinants of consumer satisfaction. Many customer satisfaction surveys mainly focus on the evaluation of functional benefits including product assortments, merchandise prices and locational convenience. Recent studies indicate that emotional/hedonic benefits strongly influence the consumer satisfaction, intention to repurchase and intention to revisit. Our study suggests that both functional values and hedonic values should be included in developing the index of consumer satisfactions. The purpose of our study is to investigate the relationship between shopping value and consumer satisfaction, and actual patronage behavior. Shopping values is defined as the difference between total benefits and total shopping costs. Total benefits include the dimensions of product quality, service quality, and hedonic benefits. Total costs are classified as the monetary costs and non-monetary cost. The conceptual framework developed for this empirical study is as follows.

The main objective of this study is to provide necessary information to improve the college curriculums to reflect the demands from the industry. As a result of the evaluation on the contribution of the engineering colleges to industries, we found out that the knowledge required in the industry was well reflected in contents of college curriculums and the number of college graduates who took the curriculums that contain knowledge and skills required in the industry was very small compared to the number of courses established in colleges. The satisfaction rate on practical application of the knowledge and skills at the work was relatively high. According to the result of evaluating curriculums of different colleges it was found out that the areas where colleges put their key focus were different by schools.

The Type of Service based multicast routing algorithm is necessary to support efficiently herogeneous applications in ATM network. In this paper I propose the Constrained Multicast Tree with Virtual Destination(DMTVD) heuristic algorithm as least cost multicast routing algorithm. The service is categorized into two types, as delay sensitive and non in CMTVD algorithm. For the delay sensitive service type, the cost optimized route is the Minimum Cost Stenier Tree connecting all the destination node group, virtual destination node group and source node with least costs, subject to the delay along the path being less than the maximum allowable end to end delay. The other side for the non-delay sensitive service, the cost optimized route is the MCST connecting all the multicast groups with least costs, subject to the traffic load is balanced in the network. The CMTVD algorithm is based on the Constrained Multicasting Tree algorithm but regards the nodes branching multiple destination nodes as virtural destination node. The experimental results show that the total route costs is enhanced 10%-15% than the CTM algorithm.

The most common deterioration cause of concrete structures in urban environment is carbonation. Recently, the $CO_2$ concentration and temperature at atmosphere is sharply increased with time due to global warming phenomena. In this study, the climate scenario IS92a, which was suggested by the IPCC, is used to consider temperature and atmospheric $CO_2$ concentration change in the model of service life prediction. The modified mathematical solution, which was based on the Fick's 1st law of diffusion, was used to reflect concrete materials properties such as the degree of hydration of concrete with elapsed time, and important parameters, which associated with deterioration rate. The techniques of service life prediction are developed introducing the method of reliability and stochastic concept to consider microclimatic condition in Seoul, South Korea. From the result of service life prediction, concrete containing high W/C ratio is shown fast carbonation rate due to $CO_2$ concentration increase. It is concluded that the deterioration of concrete structures due to carbonation is insignificant problem on the conditions that below W/C 55%, well curing concrete.

Real options valuation models are now proved as a effective valuation method both in Theoretically and empirically. However, to use real options model for early stage start-ups, additional non-financial information is crucial in the valuation process. Previous studies theoretically suggested the modified real options valuation model and process to use non-financial information in the valuation of early stage startups, but there is no empirical evidence on the suggested model. Therefore, this study investigated the effectiveness of the modified real options valuation model using a case study. The case study result showed that the modified real options valuation effectively reflect the non-financial information in early stage startups, and decrease the forecasting error in the valuation process.

This study aims to identify existing legal limitations on tattooing for beauty purposes and to suggest legalization of tattooing for beautician and necessity of institutionalization for the professional qualification system. The results of depth interviews from 10 experts in the field of beauty and law and survey from 101 respondents who experienced with tattooing are as follows. First, 10 experts pointed out that the law does not reflect reality considering the fact that a number of procedures are made illegal, and suggested opinions of the introduction of the professional qualification system. Second, only 15.7 percent of procedures had been conducted by a doctor, and non-medical practitioners showed higher quality of procedure, satisfaction, and recommendation. Side effects do not differ between groups, and 73.7% of the respondents answered that the qualification system is necessary. This study empirically supports the need for improvement in government policies that reflect social awareness of tattooing for beauty purposes.

A procedure for determining the lateral load pattern for pushover analysis which includes higher mode effects is presented in this study. It is well-known that the details of future earthquakes at particular site is almost impossible to predict accurately and that the code-design spectra try to represent at least the average nature of probable future earthquakes. Thus the code-design spectrum is directly used as the input earthquakes in this paper when incorporating higher mode effects in the pushover analysis so that the efforts for selecting input motions and constructing response spectrum needed in some existing method could be avoided. A case study based on the time history analysis of a irregular steel moment frame showed that the procedure proposed in this study generally outperforms various pushover analysis procedures of ATC-40 and FEMA 273. However, the proposed procedure tended to be conservative as compared with the time history analysis method.

This paper deals with the influence of behavior of a variety of cable elements on the limit strength of steel cable-stayed bridges. The softening plastic-hinge model, which is represented in this study for the limit strength evaluation of the example bridge, considers both geometric and material nonlinearites. Geometric nonlinearity of beam-column members are accounted by using stability function, and material nonlinearity - by using CRC tangent modulus and parabolic function. Cable sag effect is considered for cable members. The result of this study shows that the limit strength of the example bridge using the equivalent of elasticity for truss straight elements is smaller than those using the cable or the catenary elements.

One of the major challenge for retrieval performance is the word mismatch between user's queries and documents in information retrieval. To solve the word mismatch problem, we propose a retrieval model based on the degree of association of query concept and word translation probabilities in translation-based model. The word translation probabilities are calculated based on the set of a sentence and its succeeding sentence pair. To validate the proposed method, we experimented on TREC AP test collection. The experimental results show that the proposed model achieved significant improvement over the language model and outperformed translation-based language model.
