Capillary electrophoresis (CE) is perceived as an attractive tool for the analysis of pharmaceuticals and biological materials because of their high separation efficiency, easy separation and low running cost. New concept of micellar electrokinetic capillary chromatography (MECC) expanded the application of CE to the separation of neutral molecules. Validation of CE as an analytical technique for quality control of pharmaceuticals should be confirmed by quantitative analysis and the peak confirmation. In this study, the quantitative analyses of various types of neutral, acidic and basic components (acetaminophen, caffeine, ascorbic acid, riboflavin, thiamine, chlorpheniramine, phenylpropanolamine, dl-methylephedrine and dextromethorphan) in complex cold medicines have been accomplished using CE. Combined methods of MECC using SDS and capillary zone electrophoresis lowering the pH of running buffer were adopted to determine the ingredients in capsule type or liquid formula complex medicines without particular sample pretreatment. The results indicate that CE is a promising technique for quality control analysis of pharmaceuticals as a validation method.

Although consumer needs for better products force manufactures to put emphasis on design, often development of a product has been done without the formal process to consider consumer needs. In order to identify the implicit needs of customers and the areas of potential demand on a product, several analysis scheme such as QFD (Quality Function Deployment) has been developed. QFD, also known as the House of Quality, is the efficient tool ever created to tie product and service design decisions directly to customer wants and needs, i.e. VoC (Voice of Customer) To utilize this tool on a product design, first of all, the consumers attributes and the engineering characteristics must be exactly investigated. However there were only few studies about them on shoe design. Hence in this paper we developed an innovative framework for shoes design based on QFD. As a result, we uncovered 29 dominant human satisfaction dimensions as the consumers attributes for customer-oriented quality evaluation of a comfortable shoes. Here, 29 human satisfaction dimensions for a shoe design were identified as the dimensions that represent the human sensitivity and psychological feeling on comfortable shoes. Also, we proposed 60 human interface elements as the engineering characteristics. The relationships between human satisfaction dimensions and human interface elements were investigated. This study will help the designers and manufacturers clarify the conceptual and abstract aspect of the design evaluation by proposing a more systematic and process-oriented method.

The theory of two-dimensional quality, in particular, the Kano model that is developed by the analogy with the M-H theory, has been applied in various industry fields for more than three decades. Importance-Performance Analysis (IPA) assumes that the degree of physical fulfilment of quality attributes and the satisfaction of that attribute is linear, and therefore, it is applicable to the traditional one-dimensional attribute, not other quality types defined in the Kano's model such as attractive or must-be attribute. To solve this problem, the current study suggests a new importance-satisfaction analysis using a modified IPA in accordance with the three quality types and a diagonal method introduced by Slack (1999) to determine improvement priority. For this, I investigated 19 smartphone's quality attributes and conducted a survey of 334 university students for the results of Kano's model, which adopted from Song and Park (2012)'s study, and the importance/satisfaction of the quality attributes and the results of the priority for improvement of the 19 quality attributes. The results show that the proposed I-S priority model is better than the conventional IPA based on the comparison results of determination coefficient from the regression analysis of the two models.

Purpose: This study is on the priority for improving students satisfaction in university educational service. It explores the dimension of service quality and analyzes the relationship among quality elements, service satisfaction, and loyalty. Methods: This paper performs empirical studies by questionnaire survey. The Timko model is used for finding the degree of possible improvement of quality elements, and structural equation and regression models are used to analyze the effect of them on service satisfaction and loyalty. Also, explanatory factor analysis is used to investigate the quality determinants. Results: The quality dimension is composed of curriculum, employment support, interaction with outsiders, start-up support, learning support, counselling, and administration service. Curriculum, learning support, and administration service are positively correlated with service satisfaction, and service satisfaction has a positive effect on loyalty. Counselling service is an attractive element, and curriculum, start-up support, and learning support are indifferent elements. Conclusion: Comprehensive analysis shows that curriculum, academic advisor, and administration service have high priorities for improving educational service satisfaction.

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.

This study was aimed at learning how the service quality of family restaurants affects guest satisfaction and their intention to visit the restaurants once again. The method of the study was based on books and various data at home and abroad that contain service quality and guest satisfaction and guest intention to visit the place again as well. Previous studies and real guest survey were used as analyzing data. This study showed that interiors, sanitation and employee's hospitality are critical for the service quality of the restaurants, while employee's hospitality, the feature of interiors and exteriors, and sanitation management are important for guest satisfaction. It also indicated that high quality of the family restaurants, the feature of interiors and exteriors, and attractive environment as well influenced on guest intention to visit the place again. The study suggested that high quality of the family restaurants, high sanitation and resonable price all had an effect on guest satisfaction. More research should be conducted continuously to seek the ways to promote more visits to family restaurants through objective analyzing service quality.

Importance-Performance Analysis(IPA) holds the assumption that the degree of physical fulfilment of quality attributes and the satisfaction of that attribute is linear. Therefore, IPA can be applied to the traditional one-dimensional attributes, not to other quality elements such as attractive or must-be attributes. To overcome this problem, several articles introduced methods that integrate IPA into the concept of two-dimensional quality. However, these articles are rather conceptual focusing on the differentiation of quality attributes depend on quality elements in IPA. To provide empirical evidence of the dependent relationship between attribute importance and satisfaction in IPA, this study introduces a weighted importance approach and provides validation method using Bacon's priority model, a regression model. For this, the current research investigates 23 quality attributes of TV set for the results of Kano's model, which are adopted from Kim et al., and conducted a survey of 118 university students for the results of the importance/satisfaction and improvement priority. The result of the proposed approach shows better result than those using the conventional way, based on R-square of the regression model.

A Kano model was used to classify the quality attributes of the service robot function for actual deployment that can support and replace bank employees. Quality attributes for a total of 6 dimensions and 23 service elements were divided into bank employees and customer groups, and service priorities were derived after comparative analysis. The Decision tree model was used to supplement the excessive simplification of quality attributes by the modest number of Kano models and to classify and predict by segment market. Of the 23 services, 16 were classified into the same attributes in both groups. 6 services classified as combination attributes used a Decision tree to identify differences in perception of quality attributes among groups. In terms of basic financial services and professional financial services, it was confirmed that bank employees feel financial service robots more attractive than ordinary customers. In the design of IT convergence service, we propose a methodology for deriving quality attributes by combining a Kano model for classifying quality attributes of two groups and a Decision tree for forecasting subdivision markets.

오늘날 서비스기업에서는 다양한 방법을 통하여 고객 만족을 개선하려고 노력하고 있지만 큰 실효성을 보여주고 있지 않다. 본 연구는 품질차원의 이원적 측면을 바탕으로 하여 고객접촉정도에 따른 4가지 산업군을 연구대상(호텔 수리 교육 의료서비스)으로 선정하여 산업별로 품질의 이원적 측면을 비교 측정한 후, 이에 대한 개선 방안을 제시하는 것이다. 따라서 본 연구의 목적은 첫째, Schmenner의 서비스 프로세스 매트릭스를 기준으로 고객접촉정도에 따라 서비스산업을 선정하고 SERVQUAL을 이용하여 고객들이 원하는 요인에 대해 알아보고 Kano모형을 적용해 이를 서비스품질의 유형으로 구분하고, 둘째, Timko의 고객만족계수와 잠재적 고객만족 개선지수(PCSI Index)를 이용하여 각 산업별 우선고려사항을 도출하고 이를 비교하여 고객만족을 높일 수 있는 방안을 제시하는 것이다. 본 연구의 결과, 우선 첫째, 4가지 서비스산업에서 공통적으로 '현대적 외관/시설'이 모두 매력적 품질로 분류되었으며 고객만족계수 역시 모두 높게 나타났다. 이는 서비스산업에서 유형성 측면이 고객들의 서비스 품질 평가기준에서 매우 높은 중요도를 갖고 있다는 것으로 해석할 수 있다. 둘째, 수리서비스를 제외한 3가지 서비스산업에서는 고객의 입장을 이해하고 이를 해결하고자 하는 유연성을 갖는 공감성 측면의 개선으로 인하여 고객만족도를 향상 시킬 수 있다는 것을 시사하고 있다. 셋째, 이 4가지 서비스산업에서 공통적인 부분은 모두 공감성 측면에 대하여 매력적 품질속성으로 분류가 되었지만 현재의 만족도는 고객의 기대수준에 미치지 못하였기에 본 공감성 측면에 대한 개선이 우선적으로 이루어져야 한다는 것을 확인할 수 있었다.
