This study examines the awareness of the curriculum of the cabin service major students at 2 year colleges through the CIPP (Context, Input, Process, Product) evaluation model and an empirical analysis on how their awareness affects Service Orientation and Service Hospitality. It was proven that the CIPP evaluation model has a positive effect on the satisfaction of their department, and also has a meaningful effect on Service Hospitality and Service Orientation statistically. However, the satisfaction of their department itself is not associated with the increase of Service Orientation and Service Hospitality so it negatively affected them. Moreover, both the Service Management program(Process) and Service Attitude(Product) have a meaningful effect on Service Hospitality, and Service Hospitality also has a meaningful effect on Service Orientation. So it resulted in a casual relationship among them. As a result, it is desperately necessary to promote an educational environment that will increase the satisfaction of the department and help students to become flight attendants. It is also necessary to increase awareness of the Service Management program(Process) and Service Attitude(Product).

New product development (NPD) is defined as the transformation of a market opportunity and a set of assumptions about product technology into a product available for sale. Managers charged with project selection decisions in the NPD process, such as go/no-go choices and specific resource allocation decisions, are faced with a complicated problem. Therefore, the ability to develop new successful products has identifies as a major determinant in sustaining a firm's competitive advantage. The purpose of this study is to develop a new evaluation model for NPD project selection in the high -tech industry using support vector machines (SYM). The evaluation model is developed through two phases. In the first phase, binary (go/no-go) classification prediction model, i.e. SVM for high-tech NPD project selection is developed. In the second phase. using the predicted output value of SVM, feasibility grade is calculated for the final NPD project decision making. In this study, the feasibility grades are also divided as three level grades. We assume that the frequency of NPD project cases is symmetrically determined according to the feasibility grades and misclassification errors are partially minimized by the multiple grades. However, the horizon of grade level can be changed by firms' NPD strategy. Our proposed feasibility grade method is more reasonable in NPD decision problems by considering particularly risk factor of NPD in viewpoints of future NPD success probability. In our empirical study using Korean NPD cases, the SVM significantly outperformed ANN and logistic regression as benchmark models in hit ratio. And the feasibility grades generated from the predicted output value of SVM showed that they can offer a useful guideline for NPD project selection.

Purpose: In this paper, we developed a reliability index (RI) to efficiently compare reliability of products based on the design, development and production information such as reliability tests, quality, product life-cycle management. RI also can be applied to reliability prediction of a novel product as well as comparison evaluation among existing products. Methods: For evaluating RI, we proposed evaluation process which is composed of five steps. Target modules are selected based on warranty data and correlation analysis. Scores of selected target modules are calculated by scoring function. Finally, weights of RI model are determined by optimization method. Results: This paper presented an empirical analysis based on failure data of mobile devices. In this case study, we demonstrated that there is a direct correlation between evaluated RI and field failure probability of each product. Conclusion: We proposed the index for comprehensive and effective assessment of product reliability level. From the procedure of this study, we expected to be applied for reliability estimation of novel products and deduction of field failure-related factors.

한 칠레는 2011년 현재 한국 수출대상국 중 33위, 수입대상국 중 21위의 적자교역국이다. 그러나 칠레는 수출이 급증함에 따라 칠레 수입시장에서 한국산 제품의 점유율이 FTA 발표 전인 2003년 3.1%에서 2008년에는 5.6%로 상승하였으며, 순위도 2003년 8위에서 2008년 5위로 상승하였다. 이렇듯 한국과 칠레의 FTA 체결에 따른 경제교류의 활성화로 인하여 구리 등 원자재 수입관세의 하락으로 국내 구리사용 기업의 가격 경쟁력을 향상될 뿐만 아니라 가전, 통신 기타 제조업의 수출이 점차로 증가하고 있다. 본 연구는 한 칠레 FTA 체결 후에 한국과 칠레의 교역현황을 분석하고, 한 칠레 FTA 체결에 따른 한국소비자의 칠레 제품 평가를 하여, 국내소비자가 FTA 체결국 제품에 어떠한 영향을 미치고 있는지를 분석하는데 있다. 본 연구 분석결과 '제품태도', '가격인식', '사용안전성', '사용편리성', '디자인(외형)' 등의 요인들은 칠레제품의 인식도에 대한 평가에 유의한 영향을 미치고 있으며, 반면 '품질인식' 요인은 칠레제품의 인지도에 대한 평가에 유의한 영향을 미치지 않은 것으로 분석되었다. 한 EU FTA가 발효되었고, 한 미 FTA 체결이 가시화됨으로써 한 칠레 FTA의 효과가 점차 축소될 우려를 낳고 있다. 이는 양국의 교역량의 감소로 인한 경제교류감소가 국제경제 정책을 수립하는 데 장애요인으로 등장하지 않을까 우려한다.

TFT-LCD(Thin Film Transistor Liquid Crystal Display) module is representative commercial product of FPD(Flat Panel Display). Thickness of TFT-LCD module is very thin. It is adopted for major display unit for IT devices such as Cellular Phone, Camcorder, Digital camera and etc. Due to the harsh user environment of mobile IT devices, it requires complicated structure and tight assembly. And user requirements for the mechanical functionalities of TFT-LCD module become more strict. However, TFT-LCD module is normally weak to high level transient mechanical shock. Since it uses thin crystallized panel. Therefore, anti-shock performance is classified as one of the most important design specifications. Traditionally, the product reliability against mechanical shock is confirmed by empirical method in the design-prototype-drop/impact test-redesign paradigm. The method is time-consuming and expensive process. It lacks scientific insight and quantitative evaluation. In this article, a systematic design evaluation of TFT-LCD module for mobile IT devices is presented with combinations of FEA and testing to support the optimal shock proof display design procedure.

The perceived quality is a concept considered from the consumer's perspective. So it is differ from the objective determination of product quality. Thus the consumer perception of quality is a subjective judgement of an individual and an overall feeling on the characteristics which includes the product's reliability, performance and so on. In terms of product perception, consumers utilize the product cues in evaluating the product's quality before the purchase and the cues reflecting the quality can be classifisied into intrinsic and extrinsic ones. When the quality perception is limited to the purchase situation, purchase decision dependent on surrogate indicators such as price, are inclined to increase due to the lack of information. Therefore in this study the perceived quality of apparel is controled to the purchase situation in order to examine the consumer's reaction to the price cues and for the convenience of the exploratory investigation. As a result of the empirical study, consumers show differences in quality and value perceptions to the product with the same price depending on the perception whether the price is high or low. The apparel quality evaluation process goes through the steps of "product attributes - perceived quality - perceived value - purchase intention".

Evaluations of fashion products are often influenced by consumers' knowledge of the country where the products were made in. As globalization progresses, country-of-origin information is widely regarded as a powerful cue on consumers' shopping behavior. The purpose of study was to examine the consumer evaluation of apparel products with uni-national or bi-national country of origin. The effect of price level and gender were also investigated. The empirical research design took 2${\times}$2 factorial design with the country-of-origin coincidence (uni-national vs. bi-national) and price (high vs. low) of gender (male vs. female). Consumers' ethnocentrism and country-of-origin interest were taken into account as covariates in the factorial design. The consumers' evaluation of fashion products was measured in terms of brand attitudes and product attitudes. Data from 514 respondents were analyzed with t-test, one-way ANOVA, two-way ANOVA, and ANCOVA. Results of this study affirmed the importance of price information rather than country-of-origin coincidence in brand attitudes and product attitudes. Only for male consumers, interaction effects of price and country-of-origin coincidence had significant eflects on utilitarian attitude. Effects of two covariate variables included in the study were significant for female respondents but not for male respondents.

Customer satisfaction is becoming an increasingly salient topic in many firms and in academic research. One main rationale behind this interest is that customer satisfaction is believed to be associated with fruitful customer re-visit from the firm's point of view. Some country already had index models which can measure the degree of customer satisfaction. But, such models are ordinary models which used generally the scope of nation-wide industry. Therefore, we needs some modifications to measure customer satisfaction for specific product & service and to provide the valuable feedback to specific firms. In this perspectives, this study will evaluate the customer satisfaction index about automobile company and analyze it's result for valuable feedback. This study will present a model for an integrated customer satisfaction evaluation system which used structural equation modeling. Through this study, we anticipate that it will offer the measuring method about customer satisfaction and some guideline for product design process.
