This study empirically examines the synergy effect of a corporate-level loyalty program on customer equity (CE) known as the lifetime value of current and future customers (Blattberg et al. 2009). A corporate-level loyalty program refers to a company-wide integration loyalty program at the corporate-level in which subsidiaries (multi-divisions) participate as program members. It does not merely examine whether there is an integration effect of a corporate-level loyalty program from the CE perspective, but it provides practical implications for a firm's strategic focus by identifying which value creation channels (i.e., acquisition, retention, and cross-selling), brand characteristics (i.e., size of the customer base before integration, diversity of products, and sales channel type), and consumer characteristics (i.e., customer relationship stage, transaction amount before integration, transaction period, and number of purchased brands) are affected the most by the synergy effect.

In this paper, computer simulations of the physical Phenomena occurring in the arc region before and after current zero were carried out to evaluate the dielectric recovery characteristics of two types of double-flow nozzles. A commercial CFD Program "PHOENICS" is used for the simulation and the user-coded subroutines to consider the arcing phenomena were added to this program by the authors. The computed results were verified by the comparison with the test results presented by the research group of BBC. In order to investigate the state of the arc region after current zero, the simulation was carried out with four steps. They are cold gas flow analysis, steady state arc simulation, transient arc simulation before current zero, transient hot gas flow simulation after current zero. The semi-experimental arc radiation model is adapted to consider the radiation energy transport and Prandtl′s mixing length model is employed as the turbulence model. The electric field and the magnetic field were calculated with the same grid structure used for the simulation of the flow field. The streamer criterion was introduced to evaluate the dielectric recovery characteristics after current zero. Compared with the results obtained by assuming the current zero state in the former studies, it has been found that the results obtained by considering the state before current zerowere more accurate.

In this paper, computer simulations of the physical Phenomena occurring in the arc region before and after current zero were carried out to evaluate the thermal recovery characteristics of a Laval nozzle. A commercial CFD program "PHOENICS" is used for the simulation and the user-coded subroutines to consider the arcing phenomena were added to this program by the authors. The computed results were verified by the comparison with the test results presented by the research group of GE Co.(General Electric Company). In order to investigate the state of the arc region after current zero, the simulation was carried out with three steps. They are steady state arc simulation, transient arc simulation before current zero, and transient hot-gas flow simulation after current zero. The semi-experimental arc radiation model is adapted to consider the radiation energy transport and Prandtl's mixing length model is employed as the turbulence model. The electric field and the magnetic field were calculated with the same grid structure used for the simulation of the flow field. The post-arc current was calculated to evaluate the thermal recovery characteristics after current zero. Compared with the results obtained by GE Co., it has been found that the critical RRRV(ratio of rise of recovery voltage) will be determined previously by this study.his study.

The purpose of this paper is to review current state of farm household's debt which is considered as one of the biggest problem in the rural community, to analyze the cause of farm household debt rising in Jeju province, and to make improvement schemes on how this problem of farm household debt could be alleviated. In order to achieve these objectives, raw data are collected from the interviews with 400 farming households in Jeju region. The results of the study are as follows; An average amount of total farm households debt was 42,000 thousand won in 2005, but an average of farm households debt excluding no debt farm households was increased by 10,000 thousand to 51,750 thousand won. But the debt properties are variable according to the farm type. Non-citrus farmers, younger farmers, rural area resident farmers hold more debt problems than other type. Among total farm households, 30 percent showed over 40 percent leverage ratio(debt/total assets), which is considered as risky or heavily indebted. Therefore, I designed a workout program and a program of land liquidation for heavily indebted farm households in Korea.

This article describes the current status of site-based environmental education (EE) in the Republic of Korea. Implications for site-based EE program development and operation are presented and recommendations for an improvement are provided. Questionnaires were mailed to 205 schools and organizations where site-based EE programs operated in 2002 with funding from the Korean Ministry of Environment. The questionnaire was designed and used to examine the scope, operation, and needs of site-based EE programs. The response rate was 27.3%. The results of the survey indicated that 'awareness', 'participation', and 'attitude' were addressed by the program goals and objectives more than 'knowledge' and 'skills'. The survey also indicated that activities in the programs were not variable and most were teacher/instructor-centered. Most of the programs reflected the 'connection with everyday life, direct experience and sensitivity'. There were some difficulties in motivating students and finding a good location and qualified instructional staff. Needs included well-designed program development and dissemination, professional development, increased funding support, and more effective program evaluation.

Purpose: To identify current status of university health care program. Methods: Data and information from homepages of 309 colleges or universities in South Korea were collected. The data was analyzed by frequencies, t-test, ${\chi}^2$ test with SPSS Ver. 18.0. Results: 117(37.9%) universities had organization of health care. Whether university had health care program or not had shown significantly depended on number of students, types of school (university or college), region, and existence of medical and nursing course. Medical course was shown as a strong predictor for facilitating university health care program limitedly focusing on diseases treatment. Health promotion programs have been operated in 15 universities, vaccination programs in 10 universities, and health screening in 20 universities. Conclusion: It is strongly recommended to revise the School Health Law for constructing a comprehensive university health care program consolidating health counseling and physical training.

Purpose - This study primarily aims to represent the current trend of research on CPFR as a promising supply chain collaboration program and proposes a new framework for analyzing any collaboration programs in terms of three key collaborative features. Research design, data, and methodology - This study employs a literature review of selected studies that conduct research on CPFR. CPFR is analyzed based on the proposed framework that characterizes collaboration programs in terms of three key collaborative features. Results - The analysis based on the proposed framework reveals that the current form of CPFR continues to have some collaborative features that are not fully utilized to create an advanced collaboration program. The literature review indicates that most past studies ignore critical issues including the dynamic nature of the multiple-stage supply chain system and negotiation process for collaborative agreement in CPFR implementation. Conclusions - Results indicate that CPFR can become a better supply chain collaboration program by incorporating coordinative cost payment and joint decision making processes. Based on observations on the existing literature of CPFR, this study indicates several important issues to be addressed by future studies.

The present study has a dual purpose to investigate the current state of school English library and needs required for its effective use, and to propose a reading program at the school library. The literature on school library was reviewed. A questionnaire survey was done to find out the current situation of English library at the secondary school. The analysis of 26 secondary English teachers' responses reveals that there was the absence of librarians or reading specialists at the school English library. It was also found that the uses of the English library were limited due to the absence of the specialists, no guidelines, and no link between the curriculum and the library use. A case study on a 2-week special reading program at the school English library was conducted and 15 middle school students took part in the project. The participants took pre- and post-tests to identify their reading level using a software and did a variety of reading activities using the books selected according to their level. The comparison of the tests shows that most of the students' reading level improved after the reading program. The analysis of their views on the program and its effects reveals that they gained confidence in reading and their vocabulary understanding was improved. Some suggestions are made for the effective management of the school English library.

The purpose of this study is to provide an effective program contents of information supplied by broadcasting media with the aim of developing health program models. Health programs which have been aired and are being aired on KBS I radio, KBS, EBS, Cable TV and SBS radio were analyzed in order to understand the issues of current health programs and to design a plan for improvement. In order to address current issues of health programs, the range of health information should be extended to meet various expectations from the public audience, in addition to dealing with diagnosis and treatment of illnesses. Programs should be capable of encompassing various issues such as health practice, prevention, information on medical facilities, public health policies, daily health information, and the role of patients. As health programs function as major information sources for health services, it is necessary to raise the quality and credibility of broadcasting. Broadcasting agencies has a responsible role for public health promotion through health programs. In order to make it possible for broadcasting to fulfill its social responsibility, it is advisable to develop programs that have a clear understanding of what is the cognition of the public and the level of demand in regard to health programs.

In this paper, we design an 8-bit eSuse OTP (one-time programmable) memory in consideration of EM (electro-migration) and eFuse resistance variation based on a $0.18{\mu}m$ generic process, which is used for an analog trimming application. First, we use an external program voltage to increase the program power applied an eFuse. Secondly, we apply a scheme of precharging BL to VSS prior to RWL (read word line) activation and optimize read NMOS transistors to reduce the read current flowing through a non-programmed cell. Thirdly, we design a sensing margin test circuit with a variable pull-up load out of consideration for the eFuse resistance variation of a programmed eFuse. Finally, we increase program yield of eFuse OTP memory by splitting the length of an eFuse link.
