Curricula relevant to labor market needs are often designed with the goals of individual employment and regional development at the forefront. This study provided information on regional scope by investigating the extent and determinants of the geographic mobility of vocational high school graduates and the effects of that mobility on first-job wage rates. Geographic mobility was defined as being employed in other provinces in which vocational schools were located. About 38% of graduates were employed in other provinces. Geographic mobility was positively related to gender and human capital such as health, course of study, vocational certificate, and job training. Mobility led to higher wage rates even after controlling for sample selection bias. The implication is that vocational high school curricula which focus excessively on provincial concerns may weaken a workforce's effectiveness.

This study focused on the investigation of objects and contents of environment-related chapters which were contained in the biology textbooks of middle school in the 5th curriculum, and in the 6th curriculum. As a result of objects analysis, cognitive domain such as the knowledge and information categories were allocated more than affective domain as skill, value and attitude, and behavior and participation. Compared with the 5th curriculum, the average-pages of environment-related chapters in the 6th curriculum were decreased. Environment-related chapters in the 6th curriculum also dealt negligibly with the real environmental problems in our country. Therefore the importance of the environment-related chapters of biology textbooks in the 6th curriculum was relatively deceased compared with that in the 5th curriculum. In considering the actual low optional rate of environment subject in middle school, it was thought that the reinforcing effect of environmental education can be hardly expected. Rather, the status of environment subject will grow weaker and weaker. Thus, in order to avoid the deterioration effect of its status and solve its problems, it is necessary to up-grade environment subject as obligatory course or needs strong reinforcement of environmental education.

In the Paris Climate Agreement, Korea submitted an ambitious goal of reducing the greenhouse gas emission forecast (BAU) by 37% by 2030. And as one of the countermeasures, a smart grid, an intelligent power grid, was presented. In order to apply the smart grid, EMS(Energy Management System) needs to be installed and operated in various fields, and the supply is delayed due to the lack of awareness of users and the limitations of system ROI. Therefore, recently, various data analysis and control technologies have been proposed to increase the efficiency of the installed EMS. In this study, we present a measurement control algorithm that analyzes and predicts big data collected by IoT using a SARIMA model to check and operate energy consumption of public sports facilities.

Recently there has been an apparent paradigm shift in housing market towards customer oriented approach. In the midst of increasing competition, there is indeed a need to better understand of customers, and to quickly respond to their individual needs and wants. In this background, this paper aims to show a scientific marketing approach in housing industries, and to provide general information on Japanese condominium housing market in terms of a brief historical overview and recent market situation. Results include that there exists an about twenty year time lag in the start of condominium housing supply in the private sector between Korea and Japan. Besides, more efforts should be paid to the diversity or locality of the supplied housing type or design, especially condominium apartments in Korea compared to those of Japan. Among others this paper emphasized on illustrating the actual applications of analysis on consumers' purchasing behavior and latent conscious coupled with some statistical techniques, which may lead marketers or decision makers to forecast more accurate customers demands.

The study was a descriptive research to investigate the effect of job satisfaction and self-leadership of members of small and middle-sized hospital on organizational commitment. Collection of data was conducted throughout members of small and middle-sized hospitals with explanation of purpose from 2011, Oct, 1st to 10th. Collected data was analyzed by T-test, ANOVA, Scheffe test and hierarchical regression analysis with utilizing SPSS Win 16.0. As a result of the expected effect, a degree of effect on organizational commitment has explanation 65.1%(F=183.804) on job satisfaction and self leadership. Also, it was job satisfaction that was found to be more effective, where explanation for it was ${\beta}$=.755 and self-leadership ${\beta}$=.264. With considering these facts, both factors are effective for organizational commitment. Therefore, to improve organizational commitment, it pays systemized strategies and ever more proactive efforts. To strengthen the self leadership, it needs changes in cultural aspects of hospitals to enlarge accessibility to information and opportunities for education and to expand freedom in their responsibility. Great effort on changing in cultural aspects of hospital would, based on effective interrelationship with members, improve efficacies of organization and efficiency of management.

This study is to research cost accounting practice and to analyze propriety of patients' medical payment in artificiality kidney center. The researched cost datum of the year 2012 are as follows. - Hemodialysis medical treatment was reimbursed as much as 158,001 won in case of health insured patients, but payed-off as much as 135,810 won. - The average figure of the total hospitals and clinic center is 1,603,303 won, and one time cost of hemodialysis treatment is 154,487 won. Optimal treatment pay are suggested as follows. First, Regardless of the notified classification from MOHW(Ministry of Health and Welfare), 136,000 won of fixed price payment classification needs to be reclassified by patients, severity and tobe rearranged by fixed price payment system of hospitals. Second, Fixed payment code notified by the Ministry of Health and Welfare is recommended to be simplifies and to reflect according to contents of the medical treatment rendered to patients. Third, Establishment of artificial kidney center has to be risk managed because of its huge investment. Fourth, Cost analysis model has to be maintained as basis together with appropriate application of conversion index model mixed with SGR model.

Using the service innovation system model, the development of Korean online game industry is analyzed. The model proposed by Gallouj (2002) is modified in order to reflect IT service characteristics such as network externalities. Success factors and innovations patterns of Korean online game industry are examined. First, at the early stage of her growth, Korean online game industry was not supported or coordinated by any Government policies unlike DRAM, CDMA or TFT-LCD. Many parts of technical and service innovations were unintentionally initiated by online game developing ventures without predeterminde strategies. Second, the online game industry is basically a service industry so that users' needs and technical and service characteristics are intertwined to produce innovation. The innovation system of the online game industry is quite different from conventional product technological innovation systems in a sense that there are no blueprints for innovation as well as major players in the system. Third, Government's policies for promotion of IT industry such as the broadband infrastructure installation policy, the hi-tech venture promotion policy and the military exemption policy contributed greatly to development of the online game industry. However, these policy tools were not intended for online game industry but in the end gave a great impact on the service innovation system of the online game industry.

There have been many demands for th ereal-time image compression. The image compression systems have a wide range of applications. However, real-time encoding is hard to implement because it needs a large amount of computations. In particular, the discrete cosine transform (DCT) and motion estimatio require a large number of arithmetic oeprations compared to other algorithms in MPEG-2. The conventional fasdt DCT algorithms have focused on the reduction of the number of additions more cycles and more expense in realization. Because TMS320C80 has special structure, new approach for implementation of DCT is suggested. The selection of adaptive algorithm and optimization is requried TMS320C80 are analyzed an dsome adaptive DCT algorithms are selected. The DCT algorithms are optimized and implemented. Chens and lees DCT algorithms among various fast algorithms are selected because 1-D approach is effective in the view of th einternal structure of TMS320C80. According to the simulation result, Lees algorithm is more effective in speed and has little difference in precision. On the basis of the result, the possibility of DCT implementation for real-time MPEG-2 system is verified and the required number of the processor, called advanced DSP, is decided for real-time MPEG-2 encoding and decoding.
