The main objective of this research is to investigate whether the RFM (recency-frequency-monetary value) information of a customer's redemption behavior of loyalty points can improve the prediction of future value of the customer. The conventional measurement of customer value has been primarily based on purchase transactions behavior although a customer's future behavior can be also influenced by other interactions between the customer and the firm such as redemption of rewards in a loyalty program. We theorize why a customer's redemption behavior can influence her future purchases and thereby the customer's total value based on operant learning theory, goal gradient hypothesis, and lock-in effect. Using a dataset from a major book store in Korea spanning three years between 2008 and 2010, we analyze both purchase transactions and redemption records of over 10,000 customers. The results show that the redemption-based RFM information does improve the prediction accuracy of the customer's future purchases. Based on this result, we also propose an improved estimate of customer lifetime value (CLV) by combining purchase transactions and loyalty points redemption data. Managerial implications will be also discussed for firms managing loyalty programs to maximize the total value customers.

City of Gyeongju's referendum finally offered the long-waited low-level radioactive waste disposal site in November 2005. Gyeongju's positive decision was due to the various economic rewards and incentives the national government promised to the city. 300 billion won for an accepting bonus, the location of the headquarter building of the Korean Hydro and Nuclear Power Co., and the accelerator research center and 3.25 trillion won for supporting regional development program implementation. All of the above will affect the city's infrastructure and the citizens' economic and social lives. Population, land use, economic structure, SOC and quality of life will be affected. Some will be very positive, and some will be negative. This research project will see the future of the city and forecast the demographic, economic, physical and environmental changes of the city via computer simulation's system dynamics technique. This kind of simulation will help City of Gyeongju's what to prepare for the future. The population forecasting of the year 2046 will be 662,424 with the waste disposal site, and 327,274 without the waste disposal site in Gyeongju. The waste disposal site and regional supporting program will increase 184,246 Jobs more with 1,605 agriculture and fishery, 5,369 manufacturing shops and 27,577 shops. The population increase will bring 96,726 more houses constructed in the city. Land use will also be affected. More land will be developed. And road, water plant and waste water plant will be expanded as much. The city's financial structure will be expanded, due to the increased revenues from the waste disposal site, and property tax revenues from the middle-class employees of the company, and the high-powered scientists and technologists from the accelerator research center. All in all, the future of the city will be brighter after operating the nuclear waste disposal site inside the city.

Purpose: The obesity prevention and management program led by public health centers are important in the community. This study aims to identify the current status of obesity prevention and management programs at public health centers and perceptions regarding facilitators and barriers when implementing programs. Methods: This study used a concurrent mixed methods design. A survey was conducted to investigate the current status and infrastructure of the obesity prevention and management program at eighty-three public health centers nationwide. Nine program managers and six local residents with experience in the program were interviewed by using a semi-structured questionnaires. Results: Most of the infrastructure facilities for the program were inadequate, and insufficient budgets and lack of professional staff were identified as barriers. Facilitators included diversification of program delivery methods, operator competence, and visible outcomes and rewards. For the effectiveness of the program, it is vital to have adequate assistants, a sufficient budget, various promotional methods, and connections with various institutions in the community. On this basis, it is acknowledged that the public health center serves as a platform for preventing and managing obesity in the community. Conclusion: It is expected that infrastructure improvements in public health centers and the link with community resources are needed. In addition, there is an urgent need to set standards for obesity prevention and management programs implemented in public health centers to 'resolve regional disparities'.

Purpose: The purpose of this study was to contribute to enhancing elementary school health teachers professional job performance by analyzing their job identity and job stress. Methods: The participants were 138 elementary school health teachers registered at the Busan Metropolitan City Office of Education, and the survey was conducted from the 22nd to 23rd of July, 2010. The collected data were analyzed by percentile, t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression using the SPSS/WIN 17.0 program. Results: The average percentiles of job identity and job stress were 70.6 and 64.0 respectively. Among the sub-factors of job identity, autonomy was highest as 73.5, and among the sub-factors of job stress, job demand was highest as 73.9. There were significant differences in the degree of job identity and job stress according to education status, the number of classes, job satisfaction, enthusiasm for work, and the image of nursing teachers expressed in a word. The regression model explained 21.2% of the variance of job identity. job stress explained 32.0% of the variance. Conclusion: It is important to develop various comprehensive programs for improving job identity and managing job stress. In addition, it is necessary to provide support systems including persons, promotion and rewards to school health teachers.

Purpose: This study was conducted to 1) find out the frequency of tobacco control intervention, barriers, and facilitators. 2) compare the differences in tobacco control intervention, barriers, and facilitators between oncology nurses and general nurses. Method: A sample was composed of 96 oncology nurses and 284 general nurses. The survey questionnaire was mailed out to nurses who were working at the randomly selected hospitals throughout the country. The questionnaire was adopted from the study of national survey on oncology nurse's tobacco interventions in United States by Sarnar, et al.(2000). Results: Oncology nurses were found to provide tobacco control interventions more frequently comparing to the general nurses. "Patient not motivated to quit smoking", "Lack of time", "Lack of recognition/rewards", were the most commonly identified barriers. "Patient wants to quit", "Adequate time", "Confidence in ability help people to stop smoking", were the most commonly identified facilitators. Conclusions: Although oncology nurses are in an important position in delivering tobacco interventions and providing resources, their participation in consistent delivery of a tobacco control intervention was less than desirable. To help nurses participate in the assessment of tobacco use and interventions for cessation, the development of educational program is necessary.

The competitive nature of enterprises requires organizations to foster an environment that encourages employee innovation that leads to profitability and customer satisfaction. Organizational innovation is influenced by several factors with employee behaviour being one of the important factors. Employees contribute in the innovation process and thus, it is important for organizations to understand employee expectations to demonstrate innovative work behaviour in order to create and maintain an innovative work culture. In the present study, a conceptual model based on culture, reward and program, training, compensations, leadership and systems was tested to assess that impact on employee expectations leading to innovative work behaviour. The study was conducted in the context of city-state of Singapore due to its significant emphasis on promoting and nurturing employee innovation. The model was tested using empirical data collected through a survey of employees in Singapore. The results indicate that while culture, rewards and training programs have a direct relationship on employee expectations to demonstrate innovative work behaviour, when considered together, leadership and systems are significantly and positively associated with employee expectations. These factors are usually under the control of organizations and can be enhanced through systematic interventions, thereby providing practice managers an avenue to improve employee innovation behaviour. The other implications of the findings and future scope are discussed.

Purpose: This study aimed to identify factors influencing depressive symptoms in public and private sector employees. Methods: Survey data on 23,602 workers who had worked in the public or private sector were obtained from the 2014 Korean Working Condition Survey (KWCS). Symptoms of depression were measured using the WHO-5 Well-being Index. Data were analyzed using a $x^2$ test, t-test, and multivariate stepwise logistic regression to determine the factors affecting the symptoms of depression. Results: First, the prevalence of depressive symptoms was 41.1 % in public sector employees and 43.4 % in private sector employees. Second, the factors commonly affecting depressive symptoms in public and private sector employees were residence area, cognitive demands, development opportunities, social support from colleagues, social support from supervisors, social community at work, job rewards, and work-family conflict. In addition, age, company size, atypical work, ergonomic risks, quantitative demands, emotional demands, influence, and job insecurity were found to be predictors of depressive symptoms unique to private sector employees. Conclusion: Mental health programs including the employee assistance program (EAP) should be developed and implemented after considering the risk factors affecting depressive symptoms.
