This study aims to analyze the effects of the Agricultural Ecological Environment Program, the first agri-environmental policy in Korea. To this end, as Janghyeon in Boryeong City and Hwaam in Cheongyang County were set up as experimental group. And similar to these villages nearby, Hwangryong in Boryeong and Gideok in Cheongyang have been set up as the control group. It compared and analyzed the farms' level and structure of awareness. The main results of the study can be summarized as follows. First, the Agricultural Ecological Environment Program improved the awareness of safe agricultural product cultivation and agricultural ecological environment stabilize. However, the contribution to the formation of rural community has not been statistically significant. Second, it was found that the farms clearly distinguish and recognize the safe agricultural products cultivation, the agricultural ecological environment stabilize, and the formation of rural community. On the other hand, it was found that the control group that did not participate in the agricultural ecological and environmental program was confused on the recognition of three things or did not recognize them. To summarized, the future agri-environmental policy can be grafted onto regional development policy. So, the areas of agri-environmental policy should include both agriculture and rural. In addition, the scientific discipline and movement approach should be all used also in the method of approach.

Urban planning is the task to explore measures for bringing order to the change in urban space of future predicted in relation to the size and purpose of the land and a variety of facilities in cities in order to present the environment that can promote the qualitative improvement of activities of residents, ensure orderly urban space of future, and create appropriate urban environment which meets the desire of citizens by anticipating the urban development on the basis of overall activities such as politics, economics, culture, etc, so that the improvement in urban life can be accomplished ultimately. Therefore, this study attempted to examine current conditions information necessary for establishing policies pursuant to the national land development plan and regional development, as well as respond to the needs of urban residents who need the improvement of settlement environment including various amenities for the convenience of life, by shifting away form the macroscopic and one-size-fits top-down approach of development so far and aiming a balanced development of national land in quest for welfare society and by utilizing the urban index as the basic prior task necessary for seeking the shift ind the direction of policies and setting the direction for policies on the basis of the top-down development approach which suits the anticipation and hope of local residents as the subject of development, considering the growing interest in the shift in the policies for regional development in this era of localization. Techniques for urban planning need to be applied, such as the prior planning and the following development, along with the support at the policy level for achieving the improvement in the related sector, in order to induce continuos urban deelopment based on the establishment of healthy and sound settlement environment, and furthermore, the efforts must be drven forward to improve the urban settlement environment while the urban planning and policies are established.

This study developed diagnostic system to understand the level of welfare cultural service and infrastructure in rural areas. The applicability was reviewed through the Delphi survey and the sample survey of 60 villages. The diagnostic indicators consist of three areas: the demand area, supply area, and delivery area. The demand area consists of 8 indicators, 25 indicators for welfare services and infrastructure (healthcare, social welfare) and 32 indicators for cultural services and infrastructure (culture, education, leisure sports). The service delivery area was divided into service supply area access and traffic accessibility (public transport use status and rural transport model status) by each indicator. A diagnostic system was applied to 60 villages. Services and infrastructure for rural welfare and culture were supplied more in the Si area than Gun area. The delivery area was easier to access the Gun area than Si area. In the case of traffic access, public transportation was more frequently used in the Si area than Gun area, and the rural transportation model was found to have a relatively large amount in the Gun area compared to Si area. The diagnosis system about services and infrastructure for rural welfare and culture will provide information necessary for establishment and decision making of regional development policy taking into account characteristics of rural areas in the future.

We investigated the anti-tumor effects and molecular mechanism of Brazil, China and Korean regional propolis on HeLa ovarian cancer cell line. Each propolis extracts was prepared by ethanol extraction method. Cytotoxicity of propolis extracts was determinated by EZ-cytox cell viability assay. To necessity of anti-tumor effect and molecular mechanism of propolis, we must be adjusting propolis concentration. Due to 100 ㎍/mL of propolis extract were reduced cell viability to less than 50%, we adjusted all of propolis concentration to 100 ㎍/mL. By Western blotting analysis, we confirmed that anti-tumor mechanism of Brazil, China and Korea regional propolis has significantly difference. All of propolis was activated apoptosis related molecules such as PARP, caspase-3. However, cell proliferation signaling molecules including Akt1, ERK and Bcl-2 were reduced the protein expression level. Especially, the expression of tumor suppressor protein p53 was significantly increased in propolis-treated group such as Gyeonggi, Chungbuk, Chungnam, Jeonbuk, Gyeongnam and China. The phosphorylation of Bax which as apoptosis indicator was appeared in propolis-treated group such as Gyeonggi, Gangwon, Chungnam, Gyeongbuk, China. In this results showed that the regional propolis has completely different mechanism in anti-tumor. Thus, propolis extracts may be useful source of functional materials on anti-cancer and it will be able to choose the suitable propolis for cancer therapy by analyzing individual characteristics.

The objectives of this study were to identify the roles of local government for developing community lifelong education, and to suggest desirable directions for upbringing human resource for the future in local community. The roles of local governments have become a more difficult challenge in the context of the ever increasing trends of rural population's moving toward urban areas mainly for the better education for their children. Even though there are regional differences in income level, educational environment, and budgetary constraints. local governments can play an important role in helping community people to build strong community in terms of economic development and enhancing the level of quality of life, and upbringing community leaders. Local governments' priority should be given to provide the better educational opportunities for students as well as community people through community lifelong educational programs.

This study assessed the efficacy of improving the accuracy of reservoir water level prediction models by employing automated machine learning models and efficient cross-validation methods for time-series data. Considering the inherent complexity and non-linearity of time-series data related to reservoir water levels, we proposed an optimized approach for model selection and training. The performance of twelve models was evaluated for the Obong Reservoir in Gangneung, Gangwon Province, using the TPOT (Tree-based Pipeline Optimization Tool) and four cross-validation methods, which led to the determination of the optimal pipeline model. The pipeline model consisting of Extra Tree, Stacking Ridge Regression, and Simple Ridge Regression showed outstanding predictive performance for both training and test data, with an R² (Coefficient of determination) and NSE (Nash-Sutcliffe Efficiency) exceeding 0.93. On the other hand, for predictions of water levels 12 hours later, the pipeline model selected through time-series split cross-validation accurately captured the change pattern of time-series water level data during the test period, with an NSE exceeding 0.99. The methodology proposed in this study is expected to greatly contribute to the efficient generation of reservoir water level predictions in regions with high rainfall variability.

This study aims to analyze the impact of cement industry on region change. For this study Maepo-Eub was selected as study area, where three cement factories are located. The data for analysis were obtained from interviews, questionaire surveys and the employee list of each cement factory. The analytic procedures for this study are as follows: 1) The change of regional employment was analyzed by development was industry in terms of the permanent address, education level, occupational status of the employee. 2) The degree of population growth are analyzed by developmental staae of the industry. Some conclusions from this study follows: 1) As these cement factories were built at Maepo in the 1960's, there were plenty of employment opportunities. Thus many technicians and workers flooded in Maepo-Eub. in the 1970's with the expansion of production facilities therewere much more immigrants to the industrial region, while there were outflow in the neighboring rural areas. In the 1980's the opportunity for the employment of cement factories have been decreased due to the introduction of the automation processes and larger, sized machines. Among the employee of three cement factories the native of Chungcheongbukdo (65%; in them Danyang 52%, Jecheon 32%) is dominant, the second is from Kangwon-do (13%), and the third is from Kyungsangbuk-do (11%) adjacent to Chungcheongbuk-do. It means that there are more employment opportunity in the near places of cement factories. 2) In the period of 1960's study area had experineed rapid social increase in population by the development of cement industry. That is, cement industries created new job opportunities and attracted large population concentration into this area. In the period of 1970's the population of the industrial region have increased continuously, while the population of neighboring rural areas have decreased. In the period of 1980's the population of Maepo decreased steadily because of decrease of labour forces through automation and commuting. Thus in the early stage of idustrial development large population concentrated in the neighboring villages of cement factories, and formed residential areas, commercial areas and service areas. As agricultural and was encroached, rural people left their regions to live in the more convenient suburbs. 3) People engaged in cement industry think that cement industry has a favorable influence on regional development, such as creating job opportunity, raising income level, developing business and service sector, and leading high economic growth. While farmers and some people think that cement industries as a pollution causing factories have a harmful influence on regional development, sucha as injuring the crops, causing environmental pollution, and being harmful to health. If pollution problems are solved, I think Maepo will play an important role as a regional center which can offer employment opportunity, business and service function to pheripheral rural areas, and raise a income level.

In this paper, we attempt to study the trend of regional disparity among Chinese provinces and examine the effects of globalization on the disparities adapting panel data approach. The panel data set utilized consists of the annual variables of 29 provinces during 18 years from 1990 to 2007. The trend of inter-provincial disparities in the 1990s with the expansive trend but the trend has started to decrease since 2000. The results of the China case study show clearly that the provincial international trade level and ratio variables perform on regional income disparities remarkably in all cases. It means that the large development of international trade do with increased among provincial disparity. While due to the large area in the provinces, there exist urban-rural disparities within provinces could be one of the main source of regional disparities. Therefore, along with western regions development policy various development policies against small cities are necessary for balanced regional economic growth in China.

Study on children from international marriage so far has been conducted focusing on the school-aged children, and it uniformly presents those children as a mere being with problem, overlooking regional variables of rural area. Hence, this study aims to seek various means of adaptation of children from international marriage by considering both variables rural area and adolescence. For this study, six children from international marriage living in the rural area of H county in Jeonlanamdo were chosen, in-dept interview were conducted, and Giorgi(1985) was used to analyze qualitative data. The results shows that these adolescences appear to have extensive experiences in the areas of learning, personal relationship, home and identity. Level of academic achievement was influenced by what school they attend to, and personal relationship aspect was affected by prejudice and discriminative perception from people around them. In addition, in home environment, hatred toward father, sympathy for mother, comparison with mothers who have great cultural adaptation skills, and pressure as the firstborn appear to be on the increase. Adolescent children tend to be addicted to internet games in order to escape from anxiety, experiencing identity crisis. They tend to be negative about international marriage of their parents, and exhibit behaviors refusing values and religious view of their parents. At the conclusion, limitation of the study and suggestion for further study are presented.

Purpose: This study was conducted to differentiate the factors associated with the BMI group of adolescents between rural and urban areas, and provide baseline data in the development of health education programs considering their personal and environmental characteristics. Methods: Secondary data analysis was performed using the data from an on-line survey of the 9th adolescence behavioral health in 2013. The instruments included general, behavioral, and psychosocial characteristics. This study was a cross-sectional survey conducted with 26,513 adolescents. The data were analyzed using a t-test, two-way ANOVA, and multinomial logistic regression analysis. Results: Significant differences in the prevalence of obesity between urban and rural areas were nated and rural areas exhibited a higher prevalence of obese adolescents (p<0.05). The factors associated with the BMI group were the mothers' education level (low) and lower age of adolescents (middle school) in rural areas, wherase those for urban areas were gender (boys) and the fathers' education level (low) (p<0.05). Conclusion: Because there was a significant difference in the prevalence of obesity between rural and urban areas, it is necessary to develop a tailored education program considering the regional and environmental characteristics that the adolescents belonged to in order to prevent and control adolescent obesity.
