This study examined relationship among fashion product attributes of schoolbag, product satisfaction and repurchase intention. Total 315 questionnaires were distributed to the female/male students in Daegu and GyeongJu. Frequency analysis, factor analysis, reliability analysis, multiple regression were conducted using SPSS 13.0K statistics program as data analysis. The independent sample t-test was also conductd to examine the differences among sex, domicile, middle and highschool students. The findings hum the analysis are described in the following: First, female students is higher subjective fashion product attributes(fashion, individuality, refined) and objective fashion product attributes(design, color) importance than male students in purchasing schoolbag. High school students is higher subjective fashion product attributes(fashion, individuality) and objective fashion product attributes(brand, color) importance than middle school students in purchasing schoolbag. Second, product satisfaction are positive influenced by practicality and individuality of subjective fashion product attributes. Product satisfaction are not influenced by fashion and refined of subjective fashion product attributes. Third, product satisfaction are positive influenced by brand and design of objective fashion product attributes. Product satisfaction are not influenced by price and color of objective fashion product attributes. Forth, repurchase intention in schoolbag are strong positive influenced by product satisfaction.

This study examines the effect of congruity between product and TV reality show on purchase intention of Chinese consumers. A total of 110 respondents from Chinese consumers were collected using online surveys. The results were analyzed by SPSS 22.0. Multiple Linear Regression and process analysis were used to test the hypotheses. This article found that congruity between product and TV reality show, attitude toward product placement and recall of product affected consumers' purchase intention. In addition, the frequency of consumer watching TV reality show and familiarity of product moderated the attitude toward product placement and recall of product. This study provides useful implications for sponsors to select product placement as one of their marketing promotion tool.

An ALT(accelerated life testing) method is to test a product in over-stressed conditions, and then the test result is extrapolated to an usual (normal stressed) condition. It is the major disadvantage of ALT method that the more extrapolation to an usual condition applies the bigger error is indispensable. Therefore a reliability model combining field failure data and laboratory test data is required in pratice. We propose several methods of estimating the failure rate of a product life which is assumed to follow an exponential distribution. Structural similarity and technological advances are also cosidered. Finally, We derive the acceleratio factor which can be used to predict the failure rate for a new product.

Accelerated life testing of a car is used to get information quickly on its life distribution. Test cars are no under severe conditions and fail sooner than under usual conditions. A model is fitted to the accelerated failure times and then extrapolated to estimate the life distribution under usual conditions. This paper presents an accelerated test md the reliability growth theory, and applies it to some subsystems of cars during their prototype and pilot testing. The data presented illustrates explicitly the prediction of the reliability growth in the product development cycle. The application of these techniques is a part of the product assurance function that plays an important role in product reliability improvement.

디지털 VLSI 소자 테스트는 소자 규격서에 정의 된 파라메터들을 최악의 환경 상태에서 소자가 설계된 기능들이 모두 동작하는 지를 보증하는 것이다. 통신용 VLSI 소자의 고집적화에 따른 제품의 신뢰성을 향상하는 것이 VLSI 소자 테스트에서 중요한 고려사항이 된다. 통신용 소자의 신뢰성 향상을 위해서 테스트 파라메터들이 증가되고 테스트 시간이 늘어난다. 데스트 종류는 크게 펑션 데스트, DC 파라메터 테스트 및 AC 파라메터 테스트로 나눌 수 있다 소자의 특성과 신뢰성을 분석하는 기존의 데스트 항목들 중에는 핀간 단락 또는 핀간 누설저항을 테스트하는 항목들이 없다. 본 논문은 핀간 현상을 모델링하고 현재의 DC 파라메터 테스트 방법을 수정하고 새로운 핀간 DC 파라메터들을 테스트하는 방법을 제안한다. 실제로 제품 테스트를 통해 테스트 방법의 수정과 추가에 따른 제품 테스트의 신뢰성 향상을 확인하였다.

실 제품을 제작하기 전 컴퓨터를 이용해 프로토타이프를 제작해 미리 제품은 평가하는 방법이 널리 사용되고 있다. 프로토타이핑 작업으로 제품의 외관을 미리 평가하는 부분은 이미 실효성을 입증 받았다. 그러나 사용자 인터페이스(User Interface) 디자인 부분에 대한 평가에서는 아직 그 유효성에 대한 연구가 충분하지 못한 형편이다. 본 연구는 프로토타이핑 방법에 의한 사용자 인터페이스 디자인 평가가 과연 적절한 방법이 될 수 있는 지에 대해 실험적 검정을 수행하였다. 대상이 되는 제품으로 전자렌지를 선택했으며 이를 컴퓨터를 이용해 프로토타이프를 제작했다. 12명의 피실험자들을 나누어 실 제품과 프로토타이프에 대한 사용성 평가를 수행하였고 그 결과를 분석하였다. 분석 결과 실 제품과 프로토타이프 사이에 작업성공률, 작업수행시간, 버튼 조작 회수 등에 차이가 있는 것으로 밝혀졌다. 이는 아직도 프로토타이핑 방법이 사용성 평가 도구로 사용하기에는 보완해야할 점이 많이 있다는 것을 의미한다. 토의에서는 이에 대한 원인 규명과 문제점 해결을 위한 보완 사항 등을 제시하였다. 본 연구의 결과는 현장에서 래피드 프로토타이핑 방법을 적용해 제품의 사용성 평가를 수행하려는 디자이너들에게 도움을 줄 수 있을 것이다

Consumer evaluate the jeans product by price brand and store because these cues be surrogate indicator that could infer the product quality. But we need to confirm if depending on these cues were rational and this is the goal of this study. method of the study was based on theoretical and empirical study. For empirical study experiments by the subjects among students of Ewha Womans University were done by using jeans as stimulus,. Data was analized by ANOVA factor analysis grouping analysis F-test Pearson's correlation duncan Test and etc 571 data was analyzed of the 600 data. The results of this study are as follows : Evaluation on jeans product were different even though they were exactly the same jeans. Therefore we could confirm the bias by price brand store when consumer evaluate jeans product. Cues like price brand store effected significantly the evaluation of jeans. Quality perception of jeans was most favorable when evaluation cues were combined with high price famous brand and high prestige store. Value perception was favorable when combined with famous brand and high prestige store but value perception on high price became lowe. Purchase intention correlate with value perception and it shows same format with value preception. The most important cue of all three was store the next was price and then brand. These three cues effect the evaluation of jeans product seperately and together.

Purpose - The current study attempts to reveal the causal relationship and identify the interrelationships among individual value, product selection attribute, and re-purchase intention of consumers when purchasing kimchi. Research design, data, and methodology - The surveys were distributed and retrieved to kimchi consumers in Seoul and Gyeonggi Province who were over 20 years old and who had purchased kimchi before. The current study utilized the self-reporting survey as the research method. Result - First, as a result of hypothesis 1 test, both internal value and external value had a significant effect. Second, as a result of hypothesis 2 test, while internal value had a significant effect, external value did not have a significant effect. Third, as a result of hypothesis 3 test, while internal value had a significant effect, external value did not have a significant effect. Fourth, as a result of hypothesis 4 test, all quality, brand, and price had a significant effect. Fifth, as a result of hypothesis 5 test, while internal value had a significant effect, external value did not have a significant effect. Conclusion - The current study aims to establish marketing and service strategies to maximize profits and secure competitive advantage in the kimchi industry through changes in the management strategy of the Korean kimchi industry.

This paper examines structural breaks and asymmetries of prices of four domestic petroleum products, i.e., gasoline, kerosene, diesel, and bunker-C, following the changes in the pricing policies pertaining to petroleum products in Korea from the government-controlled pricing system to the market pricing system. We use the monthly wholesale market price data for the sample period between July 1988 and December 2001. Using the four methods: the Chow test, the CUSUM/CUSUMQ tests, the Bayesian approach and the Dufour test, the structural behaviors of the petroleum product prices are examined. We found that structural change occurred in all petroleum products, with the exception of Kerosene, at the point of pricing policy change from government-controlled to the spot-price related pricing system. We, also conducted asymmetric analysis using the Borenstein, Cameron, and Gilbert (1997)'s model and found evidences of price asymmetry for all four product types, but in different pattern for each product.
