Coffee houses' key factors to succeed in the market are not only a basic element -the taste of coffees- but also brand image, satisfaction and consumer fidelity that food service industries take into account overall. The goal of this study is to find out the relations among brand image, brand attitude and fidelity. To this end, coffee was selected among other products due to its characteristic that the difference of its quality between brands is not very noticeable. Through an analysis of each coffee house's brand image in this saturated coffee market, the influence of brand image on consumers' preference was found out. In this process, not only a strategy for each coffee house's growth and development but also the relations between brand image, brand attitude and brand fidelity would be researched, resulting in a creation of more systematic strategies.

This research suggests a recommendation system that enables bidirectional communications between the user and system using a utility range-based product recommendation algorithm in order to provide more dynamic and personalized recommendations. The main idea of the proposed algorithm is to find the utility ranges of products based on user specified preference information and calculate the similarity by using overlapping probability of two range values. Based on the probability, we determine what products are similar to each other among the products in the product list of collaborative companies. We have also developed a Web-based application system to recommend similar products to the customer. Using the system, we carry out the experiments for the performance evaluation of the procedure. The experimental study shows that the utility range-based approach is a viable solution to the similar product recommendation problems from the viewpoint of both accuracy and satisfaction rate.

Due to the positive effect of forest space for child development, the creation and operation of forest activity space of various organizations is increasing in quantity; however, the research on practical space design and management program is insufficient. Therefore, the purpose of this study is to evaluate the space and management programs of the forest experience centers through the post-occupancy evaluation of teachers and preschoolers participating in forest activities. To do this, we analyzed the selected twelve sites through field survey, class observation, and interviews with forest education specialists, and then surveyed 115 forest education experts and childcare teachers for importance, performance, overall satisfaction, and space preference. In addition, we accessed overall satisfaction and space preference of twenty-nine preschoolers through interviews, photo-simulation, and questionnaires. As a result, the importance and performance of management program area was rated higher than the spatial characteristics area. In terms of group comparison, the group with active structured program rated two areas higher than the groups with free play. Preschoolers with structured programs preferred facility space, but preschoolers with free play preferred nature. Two preschooler groups rated forest activity as satisfactory. Based on the analysis results: 1) The composition of the forest activity space should ensure accessibility, safety, diversity of diversity, water space, connect to the forest road, and secure various terrains, trees, and natural materials; 2) The management program should ensure that forest activity programs have the proportional balance of structural programs and free play; also. management programs should plan for sufficient free playtime and a high share of play in the forest; and 3) Ensure the role and expertise of forestry specialists and run a program to increase the autonomy of preschoolers.

Serious games are purposive game. So game-developers want to achieve the desired purposes, and game-users also want to play to achieve the goals of playing games. The function of achievement-assessing is an important area of serious game. In this study, achievement-assessing style was defined as three types, that is, 'all-in-one', 'complex', and 'separation'. Accordingly, we analyzed which type of serious games use which type of achievement-assessing style. As a result, the survey shows that those who want to play game itself preferred 'all-in-one' above all, and those who want to stick to the purpose of game preferred 'separation' or 'complex'. In addition, the investigation of preference of achievement-assessing function shows that users, as a whole, preferred 'all-in-one'. We hope this study will be useful data to design of achievement-assessing function which achieve the purpose of game and provide users with higher satisfaction.

Contemporary smartphone competition is generally described as the battle between Apple's proprietary platform and Google's open platform. However, this competition is not limited within smartphone adoption itself. User's pre-adoption of one mobile platform via smartphone can be connected to the post-adoption of the same mobile platform based on the other smart devices (e.g. smart pad). In this study, we investigate whether user's preference to a certain platform is persistent over mobile ecology, from the pre-adoption of one smart device to the post-adoption of following devices. For this investigation, we adopt the dual-model as the ground theory, where post-adoption of IT product is explained by both dedication and constraint factors. The empirical testing first evidences that dual model works well as our research model for identifying the reasons of post-adoption. Next, we group our data into two parts in order to compare the switching behavior of iPhone users and Android phone users. iPhone users show much lower switching rate to Android based smart pads, while Android phone users show higher churn rate to iPad (49.3% : 96.3%). Especially, satisfaction showed much stronger effect than switching cost on the continuing intention of existing platform, when the analysis is given to the iPhone user's group. From this result, we can conjecture the relatively stronger loyalty of iPhone users. More managerial implications on the mobile platform strategy are driven.

The demand and production for mobile music increases as the number of smart phone users increase. Thus, the standard of selection of a user's preferred music has gotten more diverse and complicated as the range of popular music has gotten wider. Research to find intelligent techniques to ingeniously recommend music on user preferences under mobile environment is actively being conducted. However, existing music recommendation systems do not consider and reflect users' preferences due to recommendations simply employing users' listening log. This paper suggests a personalized music-recommending system that well reflects users' preferences. Using AHP, it is possible to identify the musical preferences of every user. The user feedback based on the Bayesian network was applied to reflect continuous user's preference. The experiment was carried out among 12 participants (four groups with three persons for each group), resulting in a 87.5% satisfaction level.

This study devotes to compare the accuracy of Top-N recommendations of items transacted on the web site for customers with the accuracy of rank conformity of the real ratings with estimated ratings for customers preference about items generated from two types of collaborative filtering algorithms. One is Neighborhood Based Collaborative Filtering Algorithm(NBCFA) and the other is Correspondence Mean Algorithm(CMA). The result of this study shows the accuracy of Top-N recommendations and the rank conformity of real ratings with estimated ratings generated by CMA are better than that of NBCFA. It would be expected that the customer's satisfaction in Recommender System is more improved by using the prediction result from CMA than NBCFA, and then Using CMA in collaborative filtering recommender system is more efficient than using NBCFA.

Objectives : Computer-based test (CBT) will be introduced in the national examination of Korean medicine doctors from 2023. This study was aimed to provide some information, including prior considerations, to those preparing for CBT, by presenting a summary of the survey results from participants in a CBT simulation test. Methods : In December 2020, applicants from the graduating class of the college of Korean medicine from four universities participated in the simulation test for CBT. An online anonymous survey on the applicants' preference for CBT versus paper-based tests (PBT) was conducted. The questionnaire consisted of multiple-choice questions on a 5-point Likert scale and free-form questions. Results : A total of 176 students responded to the survey. Their response to CBT was generally positive. The item with the highest agreement was that it should provide a sufficient opportunity to experience CBT in the undergraduate exam (4.38±0.839). Concerns about the possibility of cheating or poor concentration were also detected. In addition to guaranteeing the stability of the CBT system, there were many comments expressing the need to supplement functions within the CBT system, including the memo or highlighter function. Conclusions : This study confirmed the feasibility of CBT including multimedia questions in the field of Korean medicine education and identified overall positive responses from those who experienced the CBT simulation test. Although time is short and there is so much to prepare, we hope this will be a leap forward for effective educational innovation in line with the changing environment of the health care education field.
