This study aims to understand why public information systems in agricultural fields have shown lower performances than other industrialized fields and industries and how these problems would be fixed and overcame. To accomplish this research purpose, this study would overview the previous studies on developing agricultural information systems in public sectors and would find out meaningful and considerable factors. This study would accept the methodologies of literature review and systems thinking approaches to understand the relationships among the found factors and to suggest the conceptual research model. Agricultural information system should take care to reduce implement and maintenance costs to reduce the negative relationships between costs and expected service value and between expected service value to perceived service value. Also, it should be understood that impersonal response would reduce the eager to use the services, so the government sectors should consider positively to adopt the concept of CRM even though the government sectors traditionally have ignored its necessity. The failure of public information systems/services may be caused not only by lack of the contents but also by the failure of the persistent post management.

The purpose of this study is to propose and test a model of customer retention in Internet shopping malls when switching barriers and comprehensive customer value exist in terms of economic and experiential aspects. The literature about customer retention propose that switching barriers are important factors other than satisfaction influencing customers' intention to remain with a specific supplier. The switching barriers mean anything that makes customers' defection difficult or costly and are consisted of perceived switching costs, attractiveness of alternatives and virtual relationships. The Customer Value Scale by Mathwick(2001) is applied to this study as economic value, shopping efficiency, service excellence, aesthetic appeal and playfulness(Zeithaml, 1988; Holbrook, 1994). The analyses showed partial support for the affirmative effect of customer values and switching costs and full support for the affirmative Influence of satisfaction on repurchase intention in the Internet shopping mall environment. But the attractiveness of alternatives and virtual relationship did not have a significant Influence like the result of Jones(1998)'s study of the service industry.

Price discount is one of the commonly used promotion strategies to increase sales and revenue. If a discount is perceived before the purchase (i.e., pre-purchase discount), consumers are likely to perceive it as a potential gain. If it is noticed after making a regular-priced purchase (i.e., post-purchase discount), consumers may develop negative emotions and attitudes. Based on the rising transparency and omnipresence of price and discount information through web and mobile platforms, we attempt to tackle an understudied topic on the negative effect of post-purchase price discount. Specifically, post-purchase discount information may increase consumers' perception of monetary loss, which may affect consumers' decision to return the product, potentially increasing the operating costs borne by retailers. Based on a close scrutinization of the current market environment and previous academic literature, we suggest a novel conceptual framework to understand consumers' perception, attitude, and behavior (perception of loss, willingness to return) upon perceiving various formats of discount promotion (absolute value vs. percentage discount) posterior to the purchase of a product. We also look at the effect of price level (low-priced vs. high-priced). For marketing practitioners, we intend to suggest optimal promotion formats that can alleviate consumers' negative perceptions and prevent additional operation costs.

Purpose Based on consumers' economic, psychological, self-development and conversion costs, this study discusses the relationship between consumers' negative attitude to their shadow work during the course of using self-service in unmanned supermarkets and their behavior. Design/methodology/approach Along with the Hirschman(1970)'s EVLN(Exit, Voice, Loyalty, and Neglect) reviewed, the proposed model of this study is based on the S-O-R model(Mehrabian and Russel, 1974) and mental accounting theory(Thaler, 1999), having empirical validation. Findings In the process of visits and consumption in unmanned supermarkets, increasing economic and psychological benefits can effectively reduce consumers' negative attitudes towards shadow work. In addition, the increase in switching costs will also effectively reduce consumers' negative attitudes towards shadow work. When shadow work holds a negative attitude, all the three kinds of actions will occur. Unmanned supermarket operators use consumers to create value while giving a certain return to them, which is conducive to the sustainable development of unmanned supermarket enterprises.

Purpose: This study was to describe the burden of aged parents caring for adult children with disabilities and related factors. Methods: The subjects were 123 caregivers aged over 65 who were caring for 18-year-old or older children with disabilities. The research tool of this study was a structured questionnaire on family burden. Data were collected from June 3 to 25, 2010, and analyzed by Cronbach's alpha, mean, standard deviation, t-test, and ANOVA using SAS 9.2 program. Results: The major findings of this study were as follows. Elderly parents caring for adult children with disabilities perceived a moderate level of burden. The burden from concern over their children's future was highest, and economic and physical burdens were higher when the parents were younger. Burden was significantly different according to parents' characteristics such as gender, perceived health status, disease, the costs of caring for disabled children, and children's characteristics such as disability rating, health status, and ADL. Conclusion: In order to reduce the burden of elderly parents caring for adult children with disabilities, we need to improve their health status and assess comprehensive policies.

Single-user spectrum sensing is susceptible to multipath effects, shadow effects, hidden terminals and other unfavorable factors, leading to misjudgment of perceived results. In order to increase the detection accuracy and reduce spectrum sensing cost, we propose an adaptive cooperative sensing strategy based on an estimated signal-to-noise ratio (SNR). Which can adaptive select different sensing strategy during the local sensing phase. When the estimated SNR is higher than the selection threshold, adaptive double threshold energy detector (ED) is implemented, otherwise cyclostationary feature detector is performed. Due to the fact that only a better sensing strategy is implemented in a period, the detection accuracy is improved under the condition of low SNR with low complexity. The local sensing node transmits the perceived results through the control channel to the fusion center (FC), and uses voting rule to make the hard decision. Thus the transmission bandwidth is effectively saved. Simulation results show that the proposed scheme can effectively improve the system detection probability, shorten the average sensing time, and has better robustness without largely increasing the costs of sensing system.

Objective : The purpose of this study was to identify characteristics of patients' self-perceived health in traditional Korean medical facilities. Method : This research was conducted based on the survey on patients whom have visited traditional Korean medical facilities in 2011 by the Ministry of Health and Welfares and Korean Institute for Health and Social Affairs. Using a sample of 3,931 (1,180 male and 2,751 female) outpatients' self-perceived health based on the data from usage and consumption of Korean Medicine. 'Healthy', 'Fair', and 'Poor Health' were used to measure patients' self-perceived health status. The data was analyzed by frequency, t-test, cross correlation analysis and multiple logistics regression analysis using the SPSS program package. Results : Sex(P<0.001), age(P<0.001), marital status(P<0.001), education(P<0.001), employment status(P<0.001), occupation(P<0.001), health insurance(P<0.001) and income level(P<0.0001) showed statistical significance. Main Treatment Facilities(P<0.001), experience of taking Korean medicine(P=0.032), experience of receiving acupuncture treatment(P<0.001), number of visits(P<0.001), medical expense (P=0.005), and subjective health status after the treatments showed statistical significance for Korean herbal medicine(P=0.038), acupuncture (P=0.001), cupping therapy(P=0.006), oriental physiotherapy(P=0.003), and treatment satisfaction(P<0.001). For subjective health status based on suffering disorders in the past three months, the response of poor health was higher in the group suffering recent illnesses. Statistical significance was seen in hypertension (P=0.002), arthritis(P<0.001), lumbar pain(P<0.001), diabetes mellitus(P=0.001), stroke(P<0.001), hwa-byung (P=0.001), gastric disorders(P=0.021), common cold(P<0.001), ankle sprain(P<0.001), muscular injury(P<0.001), lumbar sprain(p=0.009) and fracture(P=0.03). Also the number of diseases during the past three months showed statistical significance(P<0.001). Statistical significance was also seen in Level of knowledge(P<0.001), route of information(P<0.001), reliability of Korean medicine(P=0.003), insurance coverage(P=0.005), medical costs(P<0.001), and future willingness to use Korean medicine(P<0.001). As a result of the multiple logistics regression analysis, risks of subjective poor health statistically increased in female population, elderlies, medicaid beneficiaries, less educated, higher medical expense, and more disorders during the past three months. Conclusion : Patients' self-perceived health status has significant differences with each variables such as sex, age, marital status, education, health insurance, medical expense, number of diseases.
