The relationship between product quality/function and customer satisfaction has been considered an important point for the new product development. The seminal paper by Kano was the first to thoroughly address the non-linear relationship between product performance/function and customer satisfaction. In the analysis framework of the original Kano model, five factors are assumed, among which indifference factor occupies 40% in the classification scheme. When we analyze survey response using Kano model, many quality attributes can be resulted in indifference factor. This implies that some attributes which are meaningful tend to be classified as indifferent attributes for the customer satisfaction. In order to tackle this problem, a modified Kano model is proposed by reducing the indifference factor. The modified Kano model can be robust for the survey response. A survey is performed for the quality attributes of the smart phone. The response is analyzed and compared based on the original and modified Kano model. The surveyed quality characteristics of the smart phone are performance related attributes, application programs, functional attributes and subjective emotional quality attributes. Many quality attributes classified as indifference factor in the original model are classified as attractive, must-be, and expected factors, respectively.

Concurrent Engineering(CE) can provide a competitive edge for companies that have confronted with rapidly changing market requirements, such as shortening of product life cycles, high quality, low cost, diversity of customer demand, and so on. We construct a prototype of integrated information system to support a new product development process by CE concept. This integrated information system can be useful for considering concurrently all of the aspect in the product design process. In this system, an Engineering Database is constructed for gathering data of four departments; i.e. marketing, production, quality control and design department. Also DFM(Design For Manufacturability) is applied for analysis of product design.

This study verified the research hypothesis by establishing a research model to achieve the purpose of empirical analysis on the relationship between O2O platform quality and personal behavioral value and relationship quality. The main results of this study are as follows. First, information quality (hypothesis 1-1), system quality (hypothesis 1-2), service quality (hypothesis 1-3), perceived product quality (hypothesis 1-4), perceived price (Hypothesis 1-5) was statistically significant, indicating a positive effect on individual behavioral value. Second, as a result of empirical analysis of the relationship between O2O platform quality and relationship quality, hypothesis 2, information quality (hypothesis 2-1), perceived product quality (hypothesis 2-4), and perceived price (hypothesis 2-5) While there was a positive effect on quality, system quality (hypothesis 2-2) and service quality (hypothesis 2-3) were not statistically significant. Third, as a result of verifying the relationship between the relationship quality and personal behavior characteristics of hypothesis 3, as the quality of personal behavior improved as the quality of relationship improved, it was required to continuously improve and strengthen the relationship quality.

Export and import of food, agriculture, forestry, fishery products are suffering from low growth rate due to the European financial crisis, global recession, and Japan's 2012 export expansion following the aftermath of 2011 earthquake. Upon the signing and enactment of Free Trade Agreement with the U.S. and the EU, agriculture and fishery product have become the center of attention. Agriculture and fishery was reported to be 80million dollars, 1.46% of total national export, in 2012. Starting from2000, South Korea's government began its effort to expand agriculture and fishery export and as a result, export has steadily increased despite decreased consumption led by global recession. K-Sure has started an insurance program with the purpose of promoting SME business's export. It protects SME business against risk arising from credit, emergency, bad debt, and domestic price increase. This study aims to evaluate the service quality of K-Sure's insurance program via surveying SME businesses in the agriculture and fishery industry. Also this study will identify key service factors for SME businesses and explore ways to expand SME exports of agriculture and fishery by analyzing consumer satisfaction index. Results indicated service product quality factor, service communication quality factor, and social quality factor was key to improving consumer satisfaction for SME businesses in agriculture and fishery industry. Service product quality factor had a negative effect on consumer satisfaction in term of variety and results indicated that service communication quality factor's responsiveness element had minimal impact on consumer satisfaction. Conversely, all elements for social quality factor had positive effects on consumer satisfaction. Thus, leading to the conclusion that improvements in service product quality factor and service communication quality factor will indeed increase consumer satisfaction.

A systematic investigation for the process design in deep drawing is necessary to improve the quality of drawn cups. This study concentrates mainly on the influence of process design strategy on the product quality. Several types of process design were chosen from initial blank of 100mm in diameter to make final cup of 50mm in diameter. Forming analysis are carried out to find out optimal design in terms of drawing force. We assume that the case which shows minimum drawing force in the subsequent operations is the best case. Through experiments it is found that the case which shows minimum drawing force also results in minimum drawing force and better product quality than other case. Thus, it is shown that this design strategy is very effective in the improvement of quality in drawn cups.

In the quality planning phase, the techniques for measuring cost-quality trade-offs are used for the selection of the optimal design specifications when design flexibility permits significant trade-offs to be made. But the product quality is not only depends on the developing cost, but also the time for developing that product. Therefor it is important to seek a methodology for estimating time-cost-quality trade-offs associated with the quality planning projects. This paper is aimed to find a methodology of time-cost-quality trade-offs and to develop a proper algorithm.

Decision making for gas boiler consumers depends on the characteristics of products such as the price and quality as well as the brand image. Although a gas boiler is a high involvement product in terms of price, in fact, it is a low involvement product which is greatly affected by installers. This study examined variables which affect the level of satisfaction and repurchase intention by surveying about 1,000 housewives through an on-line questionnaire. The results were as follows: first, gas boiler users' general knowledge of gas boilers showed a correct-answer rate of 54.5%. The average satisfaction score of product quality (mean=5.61 out of 7) was higher than that of the satisfactionscore of the company's service (mean=5.46). Second, the level of repurchase intention was above the mid-point (mean=4.72). Multivariate regression found that product satisfaction, service satisfaction, household size, and information sources explained repurchase intentions for gas boilers to be about 50.7%. Gas boiler marketers should pay attention to the survey result in that the level of repurchase intention depends mainly on both consumer satisfaction and information sources.

Three different manual assembly techniques are evaluated by relating the effects of component quality to the total cost of the product. The results show that the choice of the scrapping or repairing the defective products or alternatively, salvaging the acceptable parts, may effect the total product cost by as much as 400 per cent. This paper emphasizes the need for accurate control quality of parts in assembly if low-cost manufacture is to be achieved.

In this study, the quality of chicken breasts from organically reared chickens was compared with that of chicken breasts from conventionally reared chickens. Broilers were raised in an indoor pen with conventional and organic production system, respectively. The diet formulation for the organically reared chickens and the production density were in accordance with the guidelines for organic chicken products. Twenty birds from each group were slaughtered and their breasts were obtained for analysis. The organic chicken breasts had a higher cooking loss, and waterholding capacity, and a lower shear force (p<0.05) compared to the conventional chicken breasts. The organic chicken breasts also showed higher $a^{\ast}$ and $b^{\ast}$ values and myoglobin contents compared with the conventional chicken breasts (p<0.05). In the fatty-acid analysis, the organic chicken breasts resulted in higher polyunsaturated fatty acid (PUFA) and unsaturated fatty acid contents, and a higher PUFA-saturated fatty acid ratio.
