This study evaluated the quality of school milk programs and analyzed the relative importance of school milk program selection attributes using conjoint analysis. The survey was conducted on students from middle and high schools in metropolitan cities that provide school milk programs. Responses were received from 414 students and the data was subjected to frequency analysis, t-test, and conjoint analysis using the SPSS Statistics Package. While evaluating white milk in the school milk program, middle school students rated 'packaging condition' (4.23) the highest, high school students rated 'nutrition' (4.64) the highest, and their evaluation of all the quality attributes was significantly different from that of middle school students (p<0.001). Overall satisfaction scores too, showed a significant difference between high school (4.46) and middle school students (4.01) (p<0.001). Processed milk & dairy products had the highest satisfaction score in the attribute of 'serving time' (4.57). The relative importance of the choice attributes of the school milk program was in the order of 'number per item' (62.260%), 'temperature' (25.708%), and 'serving method' (12.032%) for all students. The school milk program most preferred by all students and middle school students was to provide milk at a refrigerated temperature, select white milk three times a week, processed milk, fermented milk, and cheese twice a week, and provide it at the desired time.

Nearest neighbor algorithms classify an unseen input instance by selecting similar cases and use the discovered membership to make predictions about the unknown features of the input instance. The usefulness of the nearest neighbor algorithms have been demonstrated sufficiently in many real-world domains. In nearest neighbor algorithms, it is an important issue to assign proper weights to the attributes. Therefore, in this paper, we propose a new method which can automatically assigns to each attribute a weight of its importance with respect to the target attribute. The method has been implemented as a computer program and its effectiveness has been tested on a number of machine learning databases publicly available.

The purpose of this study was to analyze the key factors considered important by customers in the selection of a Korean restaurant through the use of conjoint analysis techniques. A total of 400 questionnaires were distributed over a 2-week period in October 2011, of which 354 were completed (88.5%). Statistical analysis was then carried out using the Windows 18.0 Statistics package. The research was based on the analysis of two target areas - daily meals and special purpose meals. Responses were measured by using Zaichkowsky's Personal Involvement Inventory (PII) and a 7-point Likert Scale. Overall it was found that in all areas of the results regarding the involvement related analyses, daily meals scored lower than special purpose meals. This implied that the choice of daily meals is more applicable to customers with a low level of involvement, whereas high-involvement customers were more likely to focus on special purpose meals. The analysis of high-involvement customers revealed that the quality of food, price, service quality and physical environment, in order of priority, were the most important factors in selecting a restaurant. The use of the optimum attribute combination revealed the following results: delicious food (0.601); friendly staff (0.170); clean restaurant (0.191); price of 20,000 won (-0.513). Furthermore, low-involvement customers considered the following factors as important when selecting a Korean restaurant: quality of food, followed by price, physical environment and service quality in that order. In this instance, the optimum attribute combination showed the following outcomes: tasty food (0.645); friendly staff (0.418); clean restaurant (0.365); price of 5,000 won (-0.847). These results indicated the importance of developing a marketing plan which was based specifically on a customer's involvement level, focusing on their main selection criteria when choosing a Korean restaurant.

The purpose of this study was to investigate the use behavior and satisfaction of home-baking premix products. A total of 275 questionnaires were completed and statistically analyzed by the SPSS 14.0 package. The reasons for home-baking were : fun(33.8%), quality time with the family(33.8%), and distrust in foodstuffs(13.5%). The respondents(38.9%) used home-baking premix products 2~3 times per year. And the respondents purchased home-baking premix products primarily for snack foods(83.3%). Among the selection attributes of home-baking premix products, the respondents considered the importance of 'sanitation'(m=4.16) a top priority, followed by 'taste'(m=4.15), 'ease of use'(m=4.12), 'detailed instructions' (m=4.05), 'quality of raw materials'(m=4.04), and 'origin'(m=3.91). However, in the case of satisfaction, 'ease of use' (m=3.81) was the most satisfying aspect, followed by 'detailed instructions'(m=3.67), 'sanitation'(m=3.56) and 'manufacturer' (m=3.48). According to importance-performance analysis(IPA), 'quality of raw materials' and 'origin', which were selection attributes, should be quickly improved. Also, 'taste', 'ease of use', 'detailed instructions' and 'sanitation' should be maintained. This survey found that the satisfaction levels for home-baking premix product selection attributes had a significant influence on overall satisfaction($F$=7.91, $p$ <0.001). In particular taste(${\beta}$=0.32, $t$=3.53, $p$ <0.001) had a meaningful effect on overall satisfaction. In addition, the satisfaction levels for home-baking premix product selection attributes affected repurchase intention($F$=8.61, $p$ <0.001).

In recent years, a number of Korean-themed restaurants have opened in China. It is necessary to know present situation in China and attract Chinese people so that restaurant managers can carry out marketing communication strategies to make the restaurants result in a stronger position in China. The primary objective of this research is to explore the important selection attributes when choosing a Korean-themed restaurant to dine out and to identify which attributes are critical in influencing customers' overall satisfaction. The target sample was Chinese who had visited a Korean-themed restaurant in Shenyang, China. The results of this study stated that the importance of the selection attributes varied with consumer's age, marital status, education, occupation, and the average monthly family income. Meanwhile, the satisfaction of the selection attributes varied by consumer's age, marital status, occupation, and the average monthly family income. Regression analyses demonstrated that both 'value and service' and 'food' importance factors had direct and positive impacts on the level of customers' overall satisfaction. Furthermore, 'food and price' and 'atmosphere and service' satisfaction factors have positive impacts on customers' overall satisfaction with the restaurant. Marketing implications for restaurateurs along with suggestions for future research were provided in this research.

The purpose of this study is to investigate the effect on the revisit intention and recommendation intention on the golf course selection attribute factors of Chinese golf course users using IPA. In order to carry out this study, a survey was conducted on 388 Chinese golfers, data processing and IPA analysis were conducted, and the following conclusions were obtained. First, the importance of the selection attribute was the highest in employee etiquette, and the price of restaurants and food and beverage was the highest in satisfaction. Second, as a result of the IPA matrix analysis, there were 8 selection attributes for continuous maintenance, 14 for concentration improvement, 5 for low priority, and 3 for excessive effort avoidance. Third, cost, accessibility, course facilities, auxiliary facilities, caddy expertise, and satisfaction with user management were found to affect both revisit and recommendation intentions. Since this study was limited to Chinese golfers, there may be differences in comparing the results with previous studies conducted in other countries on golf culture. Therefore, studies considering cultural diversity should be conducted in the future.

As the types of wedding ceremonies become diversified, and consumers' needs become more selective, greater importance is given to wedding planners' roles in the wedding industry, and consumers require differentiated types of wedding service. As a preliminary qualitative study in this field, an ethnographic study was conducted to identify factors valued by consumers when selecting a wedding planner in the wedding planner market, which has rapidly grown in recent years. An in-depth interview was performed with eight participants in terms of wedding planner utilization type and consumers' understanding of wedding preparation with a wedding planner. The collected data were analyzed through taxonomy, component analysis and decision table analysis; for validation, professional wedding planners were asked to review the items valued by consumers in selecting a wedding planner. Four factors - expense characteristic, wedding planners, wedding consulting companies, and customer characteristics - were identified, along with eight sub-factors (capability, service attitude, technical communication, personal factors, wedding planner encounter paths, spouse's satisfaction status, and companies). Out of these, price (within budget), wedding planners' capability, wedding planners' service attitude are expected to be meaningful in further research because they were found to be attributes commonly valued by every respondent. This study is significant in that it has made a new approach to understanding wedding planner selection attributes through ethnographic research and identified new wedding planner selection attributes.

Purpose - This research examined the effect of hedonic and utilitarian eating-out motivations on the evaluation of restaurant selection attributes in a fashion premium outlet. Additionally, the influence of experimental and functional attributes on customers' preference for hedonic eating-out motives and utilitarian eating-out motives, and variation of moderating effects through the gender was examined. Research design, data, and methodology - A survey was conducted to verify the established research hypothesis. The questionnaire items for the research were modified to fit the situation of the present study. In order to elaborate the questionnaire, the literature of the previous researchers was reviewed and supplemented. The survey conducted 207 online questionnaires for consumers who have visited domestic fashion premium outlets from July 4, 2017 to July 27, 2017. A total of 207 questionnaires were collected, and a total of 206 questionnaires were used for the empirical analysis after excluding one inappropriate response. In order to verify the reliability and validity of the measured variables, exploratory factor analysis and reliability analysis were performed using SPSS 20.0. Next, the structural equation model (SEM) statistical method was used to test the hypotheses of the study. Results - Hedonic motivation had more influence on experimental attribute importance than the functional attribute importance of the restaurant. However, this result was different depending on the gender. The effects of hedonic motives on empirical attributes were more influenced by female groups, and when influencing functional attributes, male groups were more influenced. However, it was statistically significant (p <0.05) in the female group only when the hedonic eating out motives influenced empirical attributes. Conclusions - This study analyzed the effect of eating-out motivation on the restaurant preference attributes and suggested practical implications. First, customers with hedonic eating-out motivations were evaluating experiential attributes to be more important than functional attributes. Second, for customers who are motivated to use practical eating-out habits, companies should provide services that meet practical and economic needs. In particular, female customers visiting restaurants need differentiated marketing strategies that make them feel new experiences rather than practical ones. In addition, it is necessary to study more complex and integrated studies which will influence restaurant selection attributes of premium outlets customers by adding various eating out motives and selection attributes.

The purpose of this study was to examine the importance and satisfaction of exhibition and convention destinations from the MICE(meeting, incentive tour, convention, and exhibition) planners. Overall, four results were revealed from this study. First, considering the importance of selection attributes, soundproofing, lighting, temperature, A V facilities, the space of main convention hall and exhibition were the most important attributes. Second, hypothesis 1 suggested that there were statistically significant differences in the attributes of convention destination selection based on the socio-demographic variables. More specifically, a statistically significant was found in the 17 attributes out of 5 factors and 4 demographic variables. Third, hypothesis 2 suggested that there were statistically significant in the attributes of convention destination selection based on the planning characteristics of MICE. For instance, statistically significants were found 9 attributes out of 5 factors and the 4 planning characteristics. Fourth, the regional space of exhibition and convention was the most influential to the intention to revisit, followed by exhibition and convention facilities and use cost. And also, considering the recommendation to the other MICE planners who recently have used exhibition and convention centers, the facilities was the most influential, followed by use cost and tourism space surrounding exhibition and convention centers.

Structural monitoring is the most important part of the construction and operation of the embankment dams. Appropriate instruments selection for dams is vital, as inappropriate selection causes irreparable loss in critical condition. Due to the lack of a systematic approach to determine adequate instruments, a framework based on three comparable Multi-Attribute Decision Making (MADM) methods, which are VIKOR, technique of order preference by similarity to ideal solution (TOPSIS) and Preference ranking organization method for enrichment evaluation (PROMETHEE), has been developed. MADM techniques have been widely used for optimizing priorities and determination of the most suitable alternatives. However, the results of the different methods of MADM have indicated inconsistency in ranking alternatives due to closeness of judgements from decision makers. In this study, 9 criteria and 42 geotechnical instruments have been applied. A new method has been developed to determine the decision makers' importance weights and an aggregation method has been introduced to optimally select the most suitable instruments. Consequently, the outcomes of the aggregation ranking correlate about 94% with TOPSIS and VIKOR, and 83% with PROMETHEE methods' results providing remarkably appropriate prioritisation of instruments for embankment dams.
