In this paper, a research model is proved empirically which includes factors related on the purchase intention of smart car as high innovative product in advance of commercialization. As one of relating to consumer's expectation benefit factors, individual attribute factor includes product knowledge, individual innovativeness, and sociality. Consumer's expectation benefit factor includes perceived ease-of-use, usefulness, and enjoyment. As of switching cost variables, there are financial, uncertainty, relational and psychological switching costs factors. Analysis were performed using data from the 257 respondents as random sampling among potential consumers. Purchase intention were affected by individual innovativeness mediated by perceived enjoyment, and individual sociality by perceived ease-of-use and enjoyment also. Relational switching costs factor was only a significant control variable between purchase intention with consumer's expectation benefit factor. This result presents some implications for making the new smart car's detail concept and marketing strategy related to targeting the consumer as high innovative product and technology firms including smart car makers.

This study chiefly aims to examine the relations between customer's responsive behavior and service recovery satisfaction in medical service failure. Therefore, this paper deals with the effect of medical service failure severity perceived by customers on complaint behavior and service recovery expectation, the effect of complaint appealing behavior and service recovery expectation on perceived recovery and service recovery satisfaction, and the roles of service recovery(compensation) and recovery fairness as moderating variables. According to the result of this research, it was shown that service failure severity affects complaint behavior and service recovery expectation positively, and compliant behavior and service recovery expectation affects perceived recovery performance and service recovery satisfaction positively. Moreover, the moderating roles of service recovery(compensation) and recovery fairness indicated partially significant results and affected perceived recovery performance and service recovery satisfaction direct positively. The result of this study is expected to provide support when medical institutes establish service recovery strategies.

This study explored the elements, types, and determining factors of successful aging for the Korean elderly. In order to examine the expectations of the Korean elderly, a sample of 377 elderly aged 65 and over living in Seoul and Kyunggi areas was selected and interviewed. The elements of successful aging that the Korean elderly pointed out in the interviews were: 'peaceful and comfortable life', 'self-maintenance,' 'secure social support,' and 'ostentation.' The expected elements of successful aging were further classified into three types of successful aging: 'idealized expectation.' 'self-centered expectation,' 'balanced self-other expectation.' The elderly groups sorted by the types exhibited significant differences in terms of demographic characteristics, self-evaluated economic status, and self-evaluated health status. The variables that affected the expectations were age, level of education, marital status, gender, and self-evaluated health condition. However, further analysis revealed that the factors that affected the expectation for successful aging were different for male and female elderly. The results suggest that the successful aging of Korean elderly should be understood in the context of Korean society and culture. The results could be used to better understand varied and unique life of Korean elderly, as well as in establishing a basis of intervention that meets the specific demands of the Korean elderly.

The purpose of this study was to analyze consumers' expectation. perception and satisfaction. The subjects in this study were 200 employees who were employed in a department store. They experienced nursing services from the primary care center at the department store. The results were as follows: 1. The rank of perceived significance of nursing services is tangibility, reliability, assurance, responsiveness. and empathy, respectively. 2. The rank of perceived service quality is empathy. responsiveness. assurance. reliability. and tangibility. 3. The rank of expectation and the rank of perception about nursing services are same. They are assurance, reliability, responsiveness, tangibility, and empathy respectively. 4. The regression analysis, which related the effect of perceived service quality to consumers satisfaction, had R2 value of 22.9%. From the above results, it can be concluded that the higher consumers' satisfaction can be explained by the greater perceived service quality.

The purpose of this study was to analyze sensory evaluation, to assess visual serving size and plate waste estimates of daily menu, and the identify customer expectation, perception and satisfaction. Questionnaires of sensory evaluation, serving size and were waste were developed and hand-delivered to 2,520 people. A total of 2,255 questionnaires were usable: a 89.5% response rate. Customer satisfaction questionnaires were handed out to 700 customers: (100 each at seven operations). A total of 551 were returned completed (78.7%). The data was analyzed using the SAS package program for Descriptive Analysis, t-test and ANOVA. The result of sensory evaluation showed that 'taste' was 3.20, 'freshness' 3.17, 'temperature' 3.25, 'texture' 3.15, 'appearance' 3.12, 'overall evaluation' 3.21, so these were little higher than 「normal」, that is 3.0. There was positive correlation among 'taste', 'freshness', 'temperature', 'texture', 'appearance' and 'overall evaluation'(p<.001). Serving size score was 2.97 and plate waste was 4.87, thus plate waste percentage was about 22-33%. As the result of customer expectation, perception and satisfaction of menu quality, characteristics. Customer satisfaction was defined as the difference expectation and perception and customer perceptions in theis survey were lower than expectation, thus this result implied customers dissatisfied in all menu quality characteristics. IPA analysis showed that 'diversity of menu selection' and 'menu price' was included in A area 'Focus here'.

Location-aware networks are of great importance for both civil lives and military applications. Methods based on line-of-sight (LOS) measurements suffer sever performance loss in harsh environments such as indoor scenarios, where sensors can receive both LOS and non-line-of-sight (NLOS) measurements. In this paper, we propose a data association (DA) process based on the expectation maximization (EM) algorithm, which enables us to exploit multipath components (MPCs). By setting the mapping relationship between the measurements and scatters as a latent variable, coefficients of the Gaussian mixture model are estimated. Moreover, considering the misalignment of sensor position, we propose a space-alternating generalized expectation maximization (SAGE)-based algorithms to jointly update the target localization and sensor position information. A two dimensional (2-D) circularly symmetric Gaussian distribution is employed to approximate the probability density function of the sensor's position uncertainty via the minimization of the Kullback-Leibler divergence (KLD), which enables us to calculate the expectation step with low computational complexity. Moreover, a distributed implementation is derived based on the average consensus method to improve the scalability of the proposed algorithm. Simulation results demonstrate that the proposed centralized and distributed algorithms can perform close to the Monte Carlo-based method with much lower communication overhead and computational complexity.

Public disapproval of National Assembly is resulted not only from the structural peculiarity of its decision-making process, but from the gap between public expectation of the National Assembly and its performance. While Korean electorate, being interested in politics with relatively high level of political efficacy, hold higher expectation from politics, the National Assembly fails to satisfy public expectation. In particular, irresponsible behaviors of representatives and the crippled operation of the National assembly are responsible for the low level of public trust to it. Institutional reform and individual efforts of representatives are necessary to promote public trust toward the National Assembly.

This research attempts to analyze the significant factors that affect the level of expectation and satisfaction of parents on cooking activities for their child(ren) by comparing the levels of their original expectation and satisfaction; based on the understanding of the educational values and effects of cooking activities for children. To conduct the empirical studies, 254 survey samples were collected from the parents who have had their child(ren) participate in cooking activities; in addition, the data was processed and analyzed by using various comparative statistical analysis; including t-test, IPA analysis, regression analysis, one-way ANOVA. And Duncan's multiple test was added to verify the outcome afterwards. As the result of the research, the expectation and satisfaction of parents who let their child(ren) participate in cooking activities were significantly different by such variables as 'improvement of linguistic expression,' 'development of understanding numbers and scientific concepts,' 'extension of capability to give his/her emotional expressions,' 'assistance in soothing his/her psychological stresses.' Besides, 'educational contents and methods' were revealed as another factor that influenced parents' satisfaction, and it is clarified that the level of satisfaction is significantly different according to the organizations offering activity programs.
