This research suggests an ideal role between franchisee and franchisee for survival and development of the Korean franchise business by identifying causal relationships between entrepreneurship of franchisees and their business performance. Besides, when considering multi-dimensional features of a franchise system, this study aims to show that the market orientation of the franchisee and the relationship commitment between franchisee and franchisee will play an important mediating role to achieve a better business performance. Thus specific causal relationships among sub-dimensional constructs of entrepreneurship and market orientations were investigated. They are innovativeness, risk-taking propensity, pro-activeness, information creation, intelligence generation, intelligence dissemination, response design, response implementation. The results demonstrate that pro-activeness of franchisee plays a crucial role for franchisee's business performance. It was noted that franchisor's market orientation and innovativeness is also important for high market orientation of franchisor. The higher the market orientation of franchisor was, the higher relationship commitment of franchisee was formed. By identifying the mediation effect of relationship commitment and market orientation of franchisor, this paper showed that relationship commitment positively affect the improvement of franchisee's business performance. Above all, it should be noted that this research empirically identified the relationship between franchisee's entrepreneurship and business performance that most of the previous researchers have ignored. Furthermore, the analysis was conducted at sub-dimensional construct level. It is expected that empirical results from this study will be able to provide a meaningful framework and theoretical basis for future research on franchise, entrepreneurship and market orientation.

The Korean real estate market currently is experiencing a slowdown due to the global economic crisis which has resulted from subprime mortgage lending practices. In response, the Korean government has enforced various policies, based on intend to deregulate real estate speculation, such as increasing the Loan to value ratio (LTV) in order to stimulate housing supply, demand and accompanying housing transactions. However, these policies have appeared to result in deep confusion in the Korean housing market. Furthermore, analyses for housing market forecasting particularly those which examine the impact of the international financial crisis on the Korean real estate market have been partial and fragmentary. Therefore, a comprehensive and systematical approach is required to analyze the real estate financial market and the causal nexus between market determining factors. Thus, with an integrated perspective and applying a system dynamics methodology, this paper proposes Korean Real Estate and Mortgage Market dynamics models based on the fundamental principles of housing markets, which are determined by supply and demand. As well, the potential effects of the Korean government's deregulation policies are considered by focusing on the main factor of these policies: the mortgage loan.

The purpose of this study was to examine the impact of the oral health behaviors and lifestyle of hypertension patients on their perceived periodontal diseases. The data of the 2013 community health survey were used, and the data of 55,632 patients who suffered from hypertension and who were at the ages of 19 and over was analyzed. The analying methods used in this study were chi-square test and multiple logistic regression analysis. Gender, age, marital status, education, economic activity, income level and subscription to private medical insurance were identified as the factors to affect the perceived periodontal disease of the hypertension patients, and lifestyle and oral health behaviors were found to have exerted a significant influence on perceived periodontal disease. As this study found that not only the socioeconomic characteristics of the hypertension patients but their oral health care and lifestyle were all correlated with perceived periodontal disease, how to promote the oral health of those who are susceptible to periodontal diseases should carefully be considered.

The purpose of this study is to analyze the difference in suicide rates between regions and to determine the effect of social workers on the regional suicide rate. The main analysis results are as follows. First, the suicide rates in metropolitan cities were lower than was lower than in other regions, and cities and districts were lower than those in the county area. Second, suicide rates were high in areas with many cultural and social welfare facilities per population. Suicide rates were high in low mental health facilities and low social welfare budgets. The suicide rate in rural areas was high. Third, suicide rates were high in areas with low economic requirements, areas with a high proportion of the elderly, divorce rates, and areas with a small number of social security recipients and living alone. In other words, the suicide rate in rural areas was high. Finally, social workers did not affect the difference in local suicide rates. Local social services and budgets have no real impact on suicide rates. In the future, it is necessary to improve the quality and quantity of community welfare practices that can lower community suicide rates.

Considering the fact that many students and parents spend a considerable amount of time and economic power on prior learning and that the environments of internet-based society change rapidly, it is worth examining the status and effectiveness of prior learning. In response, the study surveyed 186 first-year students of A high school in Changwon on the basic status of science prior learning. By the analysis results for the status, 39.8% of the students surveyed said they had experience in prior learning in science. Among the students experienced, 56 students who started science prior learning after the start of winter vacation in the third grade of middle school were analyzed the specific status of science prior learning and the impact of science prior learning on science achievements. The semi-subject form of pre-learning in science showed the highest response rate with 50.0 percent, and the motivation for pre-learning in science was the highest with 33.9 percent improvement in test scores. The confidence and learning intention were positive when conducting prior learning in a semi-subject form, and interest and value were positive when conducting prior learning in a self-directed form. As a result of the survey on the effect of science prior learning, 71.4% of the students who experienced science prior learning showed positive scientific achievement.

The work of teachers is tile critical element ill effective shooting. But most reform efforts have focused on tile teaching profession as a whole and effective schools. Only minimal attention has been given to the subset of teachers whose performance is marginal or incompetent, those who undermine the very concept of “educational excellence.” Teachers are the school's primary point of contact with students and, in large part, determine the educational goals and learning activities for students. How teaching is conducted has a large impact on students' abilities to educate themselves, and there is evidence that teacher quality directly affects student learning. Unfortunately, the evaluation of teachers' teaching abilities is not clear, and there are few cases that teachers has correctly feedback fly tile results of the evaluation of their abilities. In this study, we analysized and compared the teacher evaluation systems of Republic of Korea, Russian Federation, and tile United States of America. These results will be based on the improvement of tile systems. In Russian Federation, the highest year of teacher's teaching which affects on teacher's salary is 5. In the United States, it is 12-13 years. But in Korea, it is more than 30 years. That means the teachers who taught for many years are considered as competent teachers in Republic of Korea based on the economic factors of educational effects. In Russia and tile United States of America, teachers' academic backgrounds seriously affect ell teachers' salary. But ill Republic of Korea, teachers' academic background is a bit of a contribution to salary. In Russian federation, teachers' activities related to education, leaking abilities as well as academic background are also affect ell the salary. In Korea, older teachers have more advantages of salary and promotion than younger teachers. Principals and vice principals of Korea have influencing power over teachers because their judgements on teachers play an important part in teachers' promotion. But there is no such power of principals and vice principals in Russia and the United States of America. In Russian federation, the evaluation of teachers abilities is enforced periodically. The results of tile evaluation reflect on teachers' salary directly, After teachers are evaluated, some teachers can earn lower salaries than before. Teachers' academic backgrounds which affect ell teacher' salary are classified by courses. The teachers who have master degrees or dolor degrees of education earn much more money than the teachers who have master degrees and doctor degrees of pure science in Russian federation.

Crop models have been used to predict vegetable crop yield, which would have a considerable economic impact on consumers as well as producers. A small number of models have been developed to estimate growth and yield of vegetables due to limited availability of growth observation data in high-quality. In this study, we aimed to analyze the protocols designed for collection of the observation data for major vegetable crops including cabbage, radish, garlic, onion and pepper. We also designed the protocols suitable for development and verification of a vegetable crop growth model. In particular, different measures were proposed to improve the existing protocol used by Statistics Korea (KOSTAT) and Rural Development Administration (RDA), which would enhance reliability of parameter estimation for the crop model. It would be advantageous to select sampling sites in areas where reliable weather observation data can be obtained because crop models quantify the response of crop growth to given weather conditions. It is recommended to choose multiple sampling sites where climate conditions would differ. It is crucial to collect time series data for comparison between observed and simulated crop growth and yield. A crop model can be developed to predict actual yield rather than attainable yield using data for crop damage caused by diseases and pests as well as weather anomalies. A bigdata platform where the observation data are to be shared would facilitate the development of crop models for vegetable crops.

This study examines cross-national patterns of asymmetry of marriage tables with respect to educational level and tries to measure the degree of gender inequality across nations. A Primary assumption of the study is that gender inequality inhibits symmetric marriage between men and women. As men and women differ more in status, the rate of symmetric marriage between them declines thus producing asymmetric marriage with respect to social status. More specifically, the main object of the study is to develop statistical models and index with which to assess the patterns and degree of asymmetric marriage. Additionally, it is intended to assess the appropriateness of several theoretical perspectives for explaining these variations identified by the statistical models. Two most important such perspectives are industrialism and theory of politics and culture. To answer these questions, this study relies on twenty-seven marriage tables with respect to educational level, some from published tables, and some extracted from other sources. The main findings of the study are: (1) compared to less industrialized countries, more industrialized countries have lower degrees of asymmetric marriage(gender inequality) with respect to educational level, and (2) other things being equal, differences in politics and culture seem to have the some impact on marriage pattern; for instance, social democracy and state socialism reduce the degree of asymmetric marriage while the high emphasis on gender-based hierarchy in Asian countries seems to increase it In short, these results suggest a weaker or modified version of industrialists That is, while with economic growth most nations show a decline in the degrees of asymmetric marriage with respect to social status, for some nations the degrees of asymmetric marriage are affected by their specific politics or cultures.

Since understanding on spatial variability of a field is essential to pursue precision agricultural technology, a field study for field variability and variable rate fertilization of nitrogen in a direct seeding paddy was attempted. Variable rate application of nitrogen was designed with soil test, and field application was tested in a direct seeding paddy in the Kimje, Jeonbuk, Korea. The grid samples of soil was collected from the field of which unit size was 35 m by 112 m on February before irrigating of the field. Soil organic matter, available phosphate and silicate, and extractable potassium were analyzed. Variable rate fertilizer recommendation maps of nitrogen for high yielding, HY, and low input sustainable agriculture, LISA, were derived based on the soil analysis. Direct seeding of rice was performed for variable rate treatment, VRT, for the experimental plot in 2001 and 2002, and so did for three volunteer farmers' field in 2003. Yield mapping was performed by harvesting. Economic feasibility of direct seeding of rice by variable rate fertilization was evaluated. Though increased yield of variable rate application and benefit of reducing fertilizer use and environmental impact, the cost for soil test exceeded the total reduced fertilizer cost.

The purpose of this study was to examine the impact of stress on the habits of temporomandibular disorder in college students. The subjects in this study were 396 male and female students who were in their first to fourth years at five different colleges located in Jeollabuk-do. The findings of the study were as follows: As for the degree of bad oral habits, "sleeping on one side" was the most common bad oral habit, followed by "enjoying caffeinated beverages," "resting the chin on the hand or a thing" and "chewing food in one side of the mouth only." As a result of analyzing their stress by general characteristics including gender, there were significant differences according to gender in stress about school life problems, one's own problems and economic difficulties, and only stress about one's own problems statistically significantly varied with academic year. When the correlation of the factors was analyzed, perceived stress about school life problems and one's own problems had a significant positive correlation with bad oral habit scores. When a multiple linear regression analysis was made to determine the influence of general characteristics and perceived stress on bad oral habit scores, gender, academic year, self-rated oral health status, stress about school life problems and stress about one's own problems were identified as significant variables. The findings of the study illustrated that there was an organic relationship between the bad oral habits and stress of the college students.
