Purpose: This paper compares and discusses the influence on the quality classification of Kano's questionnaire which is used for the Kano model(Kano et al., 1984), the 3-point Likert-scale newly proposed by Kano and the 5-point Likert-scale presented in this study. Methods: For the comparison, the current study conducts a survey of 631 television viewers. The classification results of the three methods are then compared with those of direct classification which is adopted as a standard for classification of quality attributes. Results: The agreement rates between the results using conventional Kano's questionnaire and the results using direct classification is higher than the results using 3-point and 5-point Likert-scales. In addition, the attributes grouped as must-be or attractive in the direct classification appear to be classified as one-dimensional attributes in the Likert-scales. Conclusion: In comparison with the convensional Kano's questionnaire, the Likert-scale questions highly tend to classify the quatity attributes as one-dimensional. Although the classification results of the 3-point and 5-point Likert-scales are the same, the 5-point Likert-scale has the advantage to classify quality attributes in more detail.

A Likert scale is an often used questionnaire format. It requests respondents to specify their level of agreement to each of a list of statements. A typical question using a five-point Likert scale might make a statement. The results shows vague values. We have five-point fuzzy membership function by fuzzy valued three-point for the question and fuzzy hypothesis test the membership function by 95% confidence interval.

This study was performed to examine attitude, perception, and sensory evaluation of Jjigae HMR (Home Meal Replacement) for Americans in the L.A. area. Attitude and perception of Jjigae were conducted by 128 consumers. The questions were as follows: 1) frequencies and attitude toward soup and stew, 2) experience and frequency of Korean food intake, 3) awareness of Korean Jjigae. A total of 69.5% of American had previous experience with Korean foods. However, the frequencies of Korean food intake were once every few months (27.4%) or once a year (18.9%). The 20.2% of consumers selected Kimchi-jjigae as the best-known Korean Jjigae, and 17.1% of consumers had previous experience with Kimchi-jjigae. However, the 23.7% of consumers did not have experienced with Jjigae. Sensory evaluation was conducted using Sundubu-jjigae and Kimchi jjigae. Overall liking and flavor liking were conducted by Americans using a nine-point scale (1: Dislike extremely - 9: Like extremely). The degree of intensity for sensory attribute was also rated using a nine-point Just-About-Right(JAR) scale (1: not nearly spicy/sour enough, 5: Just-About-Right, 9: too spicy/sour). Purchasing intention was rated using a five-point scale (1: Definitely would not purchase, 5: Definitely would purchase). Overall liking and flavor liking of two jjigae (Sundubu-jjigae & Kimchi-jjigae) had a value higher than five on the nine-point scale. The level of spiciness of Sundubu-jjigae was suitable for consumers whereas spiciness of Kimchi-jjigae was significantly different from the JAR value of five points on the nine-point JAR scale, showing that Kimchi-jjigae was significantly spicier than JAR point. Purchasing intention had a value higher than three on the five-point scale.

The purpose of this study was to investigate the factors influencing health promoting lifestyles in college women thus providing the basic data necessary to establish a health promoting program. The subjects of this study were 274 college women, living in Seoul, Chung-Buk, and Kangwon, during the period from May 10 to July 15, 2000. The instruments for this study were the health promoting lifestyles scale developed by Bak, Insuk(1995), the self efficacy scale by Sherer et al. (1982), the social support scale by Su, Moonja(1988), the self-esteem scale by Rosenberg(1965) and the perceived health status scale by Lawton et al.(1982). The results of this study are as follows; 1. The average score for health promoting lifestyles was 2.45 on a 4 point scale. The health promoting lifestyles categories 'harmony relationships' (3.04) and 'sanitary life'(3.02) revealed higher scores, whereas scores for 'healthy diet' (2.32), 'exercise & activity' (2.14) and 'professional health management' (1.48) were lower. 2. The mean score for self-efficacy, social support, self esteem and perceived health status was 3.38 (on a 5 point scale), 2.88 (on a 4 point scale), 2.98(on a 4 point scale) and 3.08(on a 5 point scale) respectively. 3. Health promoting lifestyles showed significant positive correlation with self efficacy, social support, self esteem and perceived health status. 4. Stepwise multiple regression analysis revealed that the most powerful predictor of health promoting lifestyle was self efficacy. Self efficacy, social support, and perceived health status have significant effects on health promoting lifestyles. These predictive variables of health promoting lifestyles explained 25% of variance. Finally, the result of this study will provide important factors for the development of a nursing intervention program for the promotion of healthy lifestyles in college women.

This study investigates the influence of Likert scale formats such as the number of response categories and the inclusion of a mid-point from a methodological point of view using instruments that measure a fashionmarketing-related subject. Using a self-administered questionnaire, 201 respondents rated their economic clothing shopping orientation on three formats of scales that differed only in the number of response categories (ranging from 5 to 7) from February 8 to February 12, 2010. Descriptive statistics, Spearman's rank order correlation, t-test, exploratory factor analysis, confirmatory factor analysis, Pearson's correlation, and Cronbach's alpha were used in the analysis. The results are as follows. First, three scale formats were generally suitable for use due to validity and reliability. Second, the response results varied with the number of categories and the inclusion of a mid-point, although the differences were statistically insignificant (with only a few cases that differed). Third, construct validity was more secure in scales with fewer categories, whereas convergent and discriminant validity was generally good in all scale formats. Fourth, reliability coefficients were higher in scales with more categories. Fifth, the number of categories was of greater importance to instrument design than the inclusion of a mid-point. Implications for appropriate scale designs are suggested in this study.

Purpose: The purpose of this study was to identify self-leadership and attitude to patient falls and fall prevention behavior in nurses. Methods: The participants were 178 nurses from two general hospitals in Seoul. Data were collected from March 20 to May 10, 2012 using structured questionnaires which included a Self-leadership scale, Fall attitude scale, and Fall prevention scale. Data were analyzed using descriptive statistics, Pearson correlation and Hierarchial multiple regression with the SPSS/WIN 20.0 program. Results: The mean score for nurses' self-leadership was 3.48 (5 point scale). The average reported fall attitude was 3.59 (5 point scale) and fall prevention behavior was 3.26 (4 point scale). Self-leadership had a 18% explanatory power in fall attitude and a 5% explanatory power in fall prevention behavior. The factors which influenced fall prevention behavior were nurses' fall attitude (${\beta}$=.21, p=.009), fall prevention education (${\beta}$=.20, p=.007) and self-leadership (${\beta}$=.16, p=.047). All of the factors together had a 13.1% explanatory power. Conclusion: The results of this study suggest that provision of regularly fall prevention education to nurses is required and should include a program to activate their positive attitude and self-leadership in order to improve fall prevention behavior in nurses.

This study proposes a method of feature point extraction using scale-space filtering and a feature point tracking algorithm based on a texturedness similarity comparison, With well-defined operators one can select a scale parameter for feature point extraction; this affects the selection and localization of the feature points and also the performance of the tracking algorithm. This study suggests a feature extraction method using scale-space filtering, With a change in the camera's point of view or movement of an object in sequential images, the window of a feature point will have an affine transform. Traditionally, it is difficult to measure the similarity between correspondence points, and tracking errors often occur. This study also suggests a tracking algorithm that expands Shi-Tomasi-Kanade's tracking algorithm with texturedness similarity.

This study was carried out to identify the influence of continuous physical therapy on long-stay elderly patients. This study classified 92 patients who had been hospitalized for one year into experimental group who continued to perform physical therapy and control group who did not conduct physical therapy and these two groups were classified into 0.5 point-questionable group, 1 point-mild dementia group, and 2 point-moderate dementia group based on the Clinical Dementia Rating Scale(CDR) when they were hospitalized in order to analyze the changes at the early stage of hospitalization and after one year has passed. As a result, it was appeared that both in CDR 0.5-point subgroup of questionable group and in CDR 1-point subgroup of mild dementia group, CDR was statistically significantly reduced in the experimental group whose physical therapy was continuously performed than in the control group whose physical therapy was not performed(p<.05) and that there was no significant difference in changes in the CDR between experimental group and control group in CDR 2-point group, which is a moderate dementia group.

The purposes of this study were to identify the students’ perception and to evaluate the satisfaction with the quality of school foodservice in Chungbuk Province. A questionnaire survey of 900 students was conducted and 370 completed questionnaires were available for the purpose of the statistical evaluation. Statistical analyses were performed on the data utilizing the SAS V8.2 program. Importance, performance and satisfaction scale were composed of 5-Likert scales. The main results of this study were summarized as follows: The degree of importance and performance on twenty three attributes and the degree of satisfaction with four dimensions and overall satisfaction were measured according to type of school, location of school, place for eating, type of foodservice system and type of foodservice operation. The importance score was significantly higher than the performance score at all quality attributes except for the food appearance. The performance score of ‘waiting time’ and ‘atmosphere’ was less than 3 point out of 5 scale. The average satisfaction score for the quality dimensions of food, sanitation and service was 3.35, 3.19 and 3.10 point out of 5 scale, respectively. The satisfaction score for dimension of environment was 2.93 point out of 5 scale. The score for overall satisfaction was 3.27 point out of 5 scale. The satisfaction score for elementary school foodservice management was significantly higher than middle and high school foodservices. The satisfaction score for commissary foodservice operations was significantly higher than conventional foodservice operations. Using survey results as a base, the dieticians of school foodservice are required to meet the needs of the students and increase students’ satisfaction.
