With over 15,000 Thai restaurants worldwide and 5,342 in the USA alone, Thai cuisine has been repeatedly internationally acclaimed for its taste, flavors, smell, and nutritional values. The Thai Ministry of Commerce has also established a global objective to find and award the best Thai food restaurants using Thai Select Premium (TSP), Thai Select Unique (TSU), and Thai Select brand labels. Therefore, using systematic random sampling, 620 diners were selected from certified Thai Select restaurants (TSR) in either Los Angeles, New York, Miami, or Chicago to ask for their opinions concerning factors important to each restaurant's service loyalty (SL). The four constructs, 18 observed variables, and six hypotheses were analyzed using LISREL 9.1. Results revealed a significant positive effect (88% R²) on the causal factor interrelationships on TSRs' SL. Additionally, the three factors affecting SL the most were service tangibility, taste perceptions, and brand image, with total effect values of 0.94, 0.43, and 0.31, respectively. Finally, when each US diner was asked why they chose to eat Thai food, respondents overwhelmingly indicated that taste (49.50%) and healthiness (32.90%) were most important. The study also adds to the literature by highlighting the importance of Thai cuisine contributing to healthier lifestyles.

IMO introduced the concept of e-Navigation and proposed MSPs(Maritime Service Portfolios) concept to reduce marine accidents, to improve efficiency of ship operation, port operation, and ship operation technology. Korean e-Navigation defines S1 ~ S5 services, as the service concept focused on domestic e-Navigation service corresponding to IMO MSPs, and is constructing a system as an ongoing project. S2 service (onboard system remote monitoring service) among the concepts of Korean e-Navigation services, is a service concept that judges the emergency level according to risk if an abnormal condition occurs during navigation, and provides corresponding guidance to accident ships based on emergency level. The purpose of this paper is to provide a basic architecture proposal of Korean e-Navigation S2 service navigation safety module, based on the S2 service operation concept. To do this, we conducted a questionnaire survey to ask experts with experience with sailors, to respond to the subjective risk experienced by sailors considering effects of anomalies, including equipment failure relative to sailing and navigational safety. Risk level for each abnormal condition was classified. The basic algorithm design of the navigation safety module is composed of safety index (SI) calculation module based on results of questionnaire and expert opinions, safety level (SL) determination module according to safety index, and corresponding guidance generation module according to safety level. To conduct basic validation of basic architecture of the navigation safety module, simulation of the ship anomaly monitoring was performed, and results have been revealed.

Purpose - As the competition in the foodservice franchise industry and the market becomes fierce and the entry barrier is lowered, the foodservice franchisor and franchisees strive to increase their competitive advantage in the market. Therefore, the franchisor and franchisees use experience management strategies to enhance the positive experiences of customers visiting the stores. In this regard, this study examines the effects of customer-oriented activities (physical-, social-, health-, and service-oriented activities) on utilitarian and hedonic values, and loyalty using stimulus-organism-response (S-O-R) model and value-expectancy theory. Research design, data, methodology - The data were collected from panels of online survey company, who visited a foodservice franchisee within last month. The survey was conducted for about 15 days from March 7, 2019 to March 21, 2019, and about 3,500 e-mails and messages were distributed to ask for the survey. A total 412 responded and completed the questionnaires. Of the 412 completed questionaires, 12 were discarded due to missing and misinformation data and 400 were retained for further data analysis. Results --The results showed that social oriented activities, health oriented activities, and service oriented activities had positive effects on hedonic value, while physical oriented activities did not have a significant effect on hedonic value. Health oriented activities and service oriented activities had positive effects on utilitarian value, while physical oriented activities and social oriented activities had no significant effects on utilitarian value. Hedonic and utilitarian values also have a positive effect on loyalty. Conclusions - First, food service franchises should provide services and menus in consideration of the health of customers. When a customer visits the store, franchisee should provide more health-oriented food or materials and clean and comfortable conditions so as not to threaten the health of the customer. Second, the food service franchise must build a service-oriented system. Foodservice franchisor need to provide continuous service training not only to the franchisees, but also to the employees of the franchisees. Third, franchise should design a store where customers can form social exchanges through providing various information exchange to customers and making the store as a local community center.

Purpose. The purpose of this study was to provide basic data regarding the intention to use community care service based on special grading for dementia in the South Korean Society. Methods. A survey was conducted using a questionnaire adapted on the basis of literature review regarding the first to fourth grade under the long-term care insurance system for the aged from May 1 to 30, 2015 and a total of 272 questionnaires were statistically processed using SPSS 21.0. Frequency analysis, descriptive statistics, and cross-tabulation analysis were performed. The non-parametric type of test, ${\chi}^2$ test, was used for statistical testing. Results. This study obtained the following results: First, caregivers had greater intention to ask recipients to use daytime and nighttime care service. Second, there were statistically significant differences in caregivers' education, occupation, monthly average income, co-residence status, intimacy, and care-giving burden (emotional, financial, and social) and recipients' activities of daily living, instrumental activities of daily living, mental health status, dementia status, and intention to use community care service based on special grading for dementia. Conclusions. There are very few statistical data and academic materials regarding special grading for dementia, which has recently been established. The results of this study are therefore expected to help make a systematic analysis of the intention to use community care service by caregivers based on special grading for dementia.

Purpose - This study aimed to investigate the effects of customer relationship quality and perceived power on complaint behaviors in a context of service failures in a restaurant. Two different types of complaint behaviors were employed: personal complaining that disappointed customers directly approach to a service manager and public complaining that customers ask for related institutions, like consumer protection organization, for help. This study also examined the moderation effects of brand reputation on the relationships between customer perceived power and two types of complaint behaviors. Research design, data, and methodology - The author developed a structural model in which customer relationship quality is proposed to affect customer perceived power, thus influencing personal and public complaint behaviors. The model also includes the moderating role of brand reputation; the effect of customer perceived power on two types of complaint behaviors becomes stronger when brand reputation is high. To analyze the research model, a survey based on a scenario regarding the contexts of service failures in a restaurant was conducted toward 126 female college students. SPSS 22.0 and AMOS 21.0 were utilized to test the hypotheses. Results - The findings are as follows. First, customers who had positive relationships with a restaurant are more likely to perceive that they have strong power to influence the service provider. Second, customer perceived power had a significant and positive effect on both personal and public complaint behaviors. Finally, when the brand reputation for a restaurant is high, dissatisfied customers who think they can exercise influence to the restaurant complain more actively toward the service provider. Conclusions - The findings of this study are against the traditional viewpoint on customer loyalty that loyal customers compared respond more generously to the mistakes of a company, but consistent with the 'love becomes hate' effect proposed by Grégoire, Tripp, and Legoux(2009). In complaining contexts, companies should manage customers with positive and strong relationship more carefully and strategically to prevent the expansion of economic and social risks from customers' complaining behaviors. This is more significant for companies with strong brand reputations.

Recently the interest in the information privacy has been growing. Digital data can be easily transferred via Internet. Service providers ask users for private data to give customized services. Users believe that their shared data are protected as they deliver their private data securely. However, their private data may be leaked if service providers do not delete or initialize them when they expire. The possibility of information leak may lower if the service providers deal with users' private data properly. In this paper, we study the self-destruction of private data for information privacy and propose the glass-box model.

Background : One-quarter of Koreans are either students or school employeeS. Therefore, school health programs for them have high levels of cost-benefit. School health programs, though, are focused on services such as vaccination and physical examination according to administrational regulations without systemic planning. Futhermore, college health programs run autonomously, not under the supervision of the Ministry of Education. It is my intention to analyse the current status of college school health service centers and use the basic data so generated to model how they might operate at an optimal level of efficiency. Methods : I intended to investigate all 29 colleges in Seoul except some specialized colleges such as theological schools in the two-month period of August and September, 1999. I used the telephone interview method to ask questions relating to personal composition, medical equipment in use, annual expenditure and the provision of school health services. School health services were composed of three items; health servies, health education and a healthy school environment. Results : 27 college health service centers were surveyed. The median number of medical personal in each center was 2, the range was 1-31. 7 centers(25.9%) have only nurses with no doctors. Annual expenditures of 11 centers(50.1%) was less than 10 million won, 19 center(70.4%) were maintained by support from their college. Thirteen centers(48.1%) provided doctor's examinations, 6 centers(22.2%) provided dental care services, laboratory services were provided by seven centers(25.9%). Some 81.5% of the centers had vaccination programs and 44.5% had health education programs. There was no school environment program except insecticide provisions. College health service centers with school doctors differed from centers without school doctors in terms of medical equipment range, annual expenditures and annual case loads. Conclusion : The structure and function of college health service centers in Seoul are diverse. However, no center has a well-organized school health plan.

The purpose of this study was to identify attitude of hospital nurse's on death with dignity. The subjects of the study were 516 nurses. The data was analyzed by SPSS PC 19.0 program. 1) 82.8% participants agree to death with dignity, and they and their family will ask death with dignity in actual situations. 2) The average score of overall attitude on death with dignity was $3.13{\pm}0.52$. 3) With respect to the general characteristics of participants there were statistically significant difference in total score according to age, Marital Status, education level, religion, career, position, and existence of patients with incurable disease around. 4) With respect to the death with dignity related characteristics of participants there were statistically significant difference in total score according to agreement to death with dignity, request to my death with dignity, in case my family member requests death with dignity. Although many nurses had a positive concept of death with dignity, they still have ethical dilemmas in life-sustaining care. Therefore training programs on moral rights are necessary to provide guidelines foe end-of-life care.

In this paper, we study the joint radio and computational resource allocation in the ultra-dense mobile-edge computing networks. In which, the scenario which including both computation offloading and communication service is discussed. That is, some mobile users ask for computation offloading, while the others ask for communication with the minimum communication rate requirements. We formulate the problem as a joint channel assignment, power control and computational resource allocation to minimize the offloading cost of computing offloading, with the precondition that the transmission rate of communication nodes are satisfied. Since the formulated problem is a mixed-integer nonlinear programming (MINLP), which is NP-hard. By leveraging the particular mathematical structure of the problem, i.e., the computational resource allocation variable is independent with other variables in the objective function and constraints, and then the original problem is decomposed into a computational resource allocation subproblem and a joint channel assignment and power allocation subproblem. Since the former is a convex programming, the KKT (Karush-Kuhn-Tucker) conditions can be used to find the closed optimal solution. For the latter, which is still NP-hard, is further decomposed into two subproblems, i.e., the power allocation and the channel assignment, to optimize alternatively. Finally, two heuristic algorithms are proposed, i.e., the Co-channel Equal Power allocation algorithm (CEP) and the Enhanced CEP (ECEP) algorithm to obtain the suboptimal solutions. Numerical results are presented at last to verify the performance of the proposed algorithms.
