There are customer services jointly provided by two facilities so that each customer will complete the course made up of both facilities' sub-services. The two facilities are assumed invested respectively by an infrastructure owner and one subordinate facility owner, whose partnership is built on their capital investments. This paper presents a mathematical model of Stackelberg competition between the two facility owners to derive their optimal Nash equilibrium. In this study, each facility owner's profit is consisted of fixed revenue fractions of sold services, operating costs (including depreciation cost) and maintenance costs of her facility. The maintenance costs of one facility are incurred both by failures and deterioration due to usage. Moreover, for both facilities, failures are rectified immediately by minimal repairs and preventive maintenance is carried out at a fixed time epoch. Additional assumptions are also employed to develop the model such as customer arrivals are manipulated to follow a Poisson process, and each facility's lifetime is independently Weibull-distributed. The Stackelberg game proceeds as follows. At the first stage of decision making process, the infrastructure owner (acting as a leader) decides the allocation of revenue shares based on her self-interest. After observing the allocation of revenue shares, the subordinate facility owner determines her own optimal price of services. This paper investigates actions and reactions of the two partners in the system. Then analytical conditions are proposed to achieve a unique optimal Nash equilibrium. Finally, some suggestions for further research are discussed.

This paper applied the Blue Print and FMEA (Failure Mode and Effect Analysis) to education service in order to raise the education service satisfaction. First, the Blue Print is deployed to come up with strategies to overcome the fail possibility point and waiting point. Next, in order to analyze the fail factors and alternative strategies, the Blue Print of education service is applied to FMEA. The results are as follows; first, the ommission from information document by web-mail or e-mail, Second, thing that selected in spite of company uneducated, thing that omitted despite the company is target, and the unsatisfaction of attendee about training contents. Third, the delay of counsel at the telephone reply, erroneous list of course name and attendee at HRD (Human Resource Development), omission of check whether attends or not. Except for unsatisfaction of attendee, all appears at the process that service delivered. And the unsatisfaction of attendee is about education contents. Both is the factor which have influence on the education service quality. The strategies to remove the failure mode are training and manual development on service and work, a thorough management and check of information system like as ERP (Enterprise Resoure Planning), HRD, education institution list DB (Data Base), on-line application system, a development of education program to offer best education that reflect the user needs and continuously changing environment.

This study is to find the causes of the current situations of conflict between generations in regards to succession of their family farm, for the target group of graduates Korea National Agricultural College of the year 2008 and their parents. This study aims at finding a way of controlling and solving the conflicts, and of developing a course of education and training, so that through this process they can come to a rational conclusion to the conflicts that arise regarding succession of the farm, in a climate of harmony and peace. It is found that communication between parents and graduates has normally gone on well, but specific problems related to management of the farm are often present. Furthermore, there is often lack of trust and promise between the parties which often causes difficulties in preparation for the succession of the farm. On the basis of these observation, we have designed and implemented an education workshop and training, as a program in which parents and their successors participated. As a result, we found it to be very effective, but it was also found to be in need of some changes. The workshop is to be implemented in two separate stages. The first stage should focus on communication and trust between family members. Firstly, they are given the opportunity to share the list of concerns withone another, as an ice breaking activity. Secondly, they can present their own hopes or wishes. And lastly, they can communicate with one another in an effort to find resolutions that will be keep both parties satisfied. The second stage should be aimed at establishing agreements concerning succession of the farm in a harmonious and peaceful manor; the second stage is also an opportunity to discuss 'Farm management and succession'. The Korea National Agricultural College (KNAC) is in the pursuit of fostering agricultural CEO's for the future of Korea. KNAC is currently implementing a very unique system of interviews in which parents participate together with students, in order to help them make a plan for rational management of their farm and smooth succession of the farm. Although KNAC now has students present a blueprint of their own unique business plans as a graduation thesis, it is necessary for KNAC to complement this system with education and training regarding the succession of family farms. Furthermore, KNAC should also develop an education and training program that is separate for this purpose, and make it a regular course of study of KNAC in the future.

As Internet usage is rapidly spreading, tasks that were only possible offline are now available in cyber space but at the same time, new security threats such as hacking and viruses have also increased. For that reason, Comprehensive and methodical information security systems are therefore required in enterprises and organizations. Consequently, the Information Security Management System certification system has been in effect in Korea since July 2001. As of December 2012, 130 enterprises have been certified, and more than 120 ISO27001 certifications have been issued. As such, since the introduction of the ISMS certification system in Korea, the demand for the certification has been steadily increasing, and it is now recognized as an integral part of maintaining the competitiveness in an enterprise. However, the qualitative aspects of certification regarding the effectiveness of ISMS have been continuously questioned by actual customers. In order to clarify the situation and remove such doubts, this study will substantiate the fact that development and certification of ISMS positively affect the business performance of enterprises so that they will recognize the effect of obtaining ISMS certification and eventually prevent security accidents and improve their business performance by developing ISMS.

This paper analyzes and evaluates the importance of energy saving measures based on qualitative survey. Through literature review and group interviews with specialists, 4 factors, 13 measures for energy savings, and 4 evaluation criteria were selected to carry out an Analytic Hierarchy Process (AHP) analysis. At the first stage of AHP analysis, the importance of factors was derived, and then the importance of 13 measures. Lastly, the cross examination of 4 factors was carried out in order to evaluate the best possible qualitative considerations. The result revealed that 'choosing the best course weather', is the most important factor with the highest value on applicability and operational complexity criteria. These results may imply that operational considerations are regarded as a main factor to be taken into account when considering appropriate energy saving measures.

Purpose: This study aims to identify the most important quality construct among system quality, information quality, and service quality, which are integrated as the second-order construct; perceived quality, and to investigate the relationship between perceived quality, learner satisfaction, learner enjoyment, switching cost, and learner loyalty. Method: Data were collected from learners who had taken e-learning course, and the analysis was conducted in two phases. The first phase described demographic characteristics using SPSS23.0; the second phase involved the second order CFA of perceived quality and the analysis of measurement model and structural model through AMOS 23.0. Results: (1) The explanatory power of system quality, information quality, and service quality appears to be almost equal; (2) Perceived quality positively influences only both learner satisfaction and switching cost; (3) Only learner satisfaction positively influences learner loyalty and switching cost negatively influences learner loyalty. Conclusion: Learner enjoyment does not play an important role in this study, which could be extrapolated in regard to the characteristics of sample. The respondents are over high school students, who emphasize on the acquisition of knowledge rather than enjoyment. Additionally, the result implies that respondents show low loyalty in the high switching cost.

Background: To identify the risk factors and assess the role of survivin in predicting progessivity precancerous cervical lesions. Materials and Methods: This case-control study was conducted from October 2009 until May 2010. We obtained 74 samples, classified according to the degree of cervical intraepithelial neoplasia (CIN): 19 samples for CIN 1, 18 samples for CIN 2, 18 samples for CIN 3, and 19 samples as controls. Demographic profiles and risk factors assesment, histopathologic examination, HPV DNA tests, immunocytochemistry (ICC) and immunohistochemistry (IHC) staining for survivin expression were performed on all samples. Data was analyzed with bivariate and multivariate analysis. Results: Multivariate analysis revealed significant risk factors for developing precancerous cervical lesions are age <41 years, women with ${\geq}2$ sexual partners, course of education ${\geq}13$ years, use of oral contraceptives, positive high-risk HPV DNA, and high survivin expression by ICC or IHC staining. These factors were fit to a prediction model and we obtained a scoring system to predict the progressivity of CIN lesions. Conclusions: Determination of survivin expression by immunocytochemistry staining, along with other significant risk factors, can be used in a scoring system to predict the progressivity of CIN lesions. Application of this scoring system may be beneficial in determining the action of therapy towards the patient.
