This study aims to explore the policy directions to apply and activate the appropriate technology in rural areas from the perspective of the endogenous and sustainable regional development theories. To this end, according to the analysis framework based on ideas, values, and strategies that are common to both endogenous regional development strategic theories and sustainable regional development theories, in this paper, various surveys and reviews were conducted on the study areas to explore the possibility of localization of the appropriate technology. The policy implications derived from research results are as follows; first, rural areas have high potential and scalability to apply and activate the appropriate technology, particularly in the field of renewable energy, due to their nature based on local resources. Second, for the practical application of the appropriate technology, first of all, together with the establishment of the role of public sector, it is necessary to plan the projects based on the cooperation network of the relevant innovation entities within and outside the regions and to build the implementation systems. Third, the training system for high skilled manpower and indigenous entrepreneurs should be stably built in order to create independent conditions, which are key elements for growth of the appropriate technology. Fourth, there is a need to find the market and establish policies that can solve the typical economic problems of rural areas such as aging population, depopulation and decline in youth, economic unrest. Fifth, in order for the appropriate technology to contribute to socio-economic innovations and the revitalization of the virtuous circle economy in the region, technical items and various business items suitable for the industrial infrastructures and autonomous conditions of rural areas are essential.

Background: Edentulism is associated with socioeconomic status, rural residence, and chronic disease, but no studies have investigated edentulism and residence factors together. All information that drives a better understanding of the factors related to edentulism plays an important role in the planning and delivery of appropriate dental services for the elderly by national and oral health professionals. This study was designed to investigate the prevalence of edentulism in adults aged over 60 years in Korea and to examine whether there are differences in dentate status between people living in urban and rural areas after controlling for sociodemographic and other related factors. Methods: The data for this study were collected from 2013 to 2015 as part of the Korea National Health and Nutrition Examination Survey VI, those individuals aged over 60 years and who had complete datasets were included (5,071). The number of teeth and residence status were categorized into two groups: edentate and dentate (1 or more); urban and rural. Multiple multivariate logistic regression analyses were sequentially applied to assess the association between dentate status and residence status after adjusting for potential confounders. Results: Rural areas, lower household income, and lower education levels were associated with a higher edentate rate. The number of teeth was lower in rural areas than in urban areas. After adjusting for various factors, statistically significant associations were present for women, low household income, low education level, poor perceived health status, and alcohol consumption in participants. Conclusion: Elders living in rural areas had poorer oral health than elders living in urban areas. The government will need to provide effective systems for promoting oral health for elders living in rural areas.

Butyrate is known to play a significant role in energy metabolism and regulating genomic activities that influence rumen nutrition utilization and function. Thus, this study investigated the effects of an isolated butyrate-producing bacteria, Clostridium saccharobutylicum, in rumen butyrate production, fermentation parameters and microbial population in Holstein-Friesian cow. An isolated butyrate-producing bacterium from the ruminal fluid of a Holstein-Friesian cow was identified and characterized as Clostridium saccharobutylicum RNAL841125 using 16S rRNA gene sequencing and phylogenetic analyses. The bacterium was evaluated on its effects as supplement on in vitro rumen fermentation and microbial population. Supplementation with $10^6CFU/ml$ Clostridium saccharobutylicum increased (p < 0.05) microbial crude protein, butyrate and total volatile fatty acids concentration but had no significant effect on $NH_3-N$ at 24 h incubation. Butyrate and total VFA concentrations were higher (p < 0.05) in supplementation with $10^6CFU/ml$ Clostridium saccharobutylicum compared with control, with no differences observed for total gas production, $NH_3-N$ and propionate concentration. However, as the inclusion rate (CFU/ml) of C. saccharobutylicum was increased, reduction of rumen fermentation values was observed. Furthermore, butyrate-producing bacteria and Fibrobacter succinogenes population in the rumen increased in response with supplementation of C. saccharobutylicum, while no differences in the population in total bacteria, protozoa and fungi were observed among treatments. Overall, our study suggests that supplementation with $10^6CFU/ml$ C. saccharobutylicum has the potential to improve ruminal fermentation through increased concentrations of butyrate and total volatile fatty acid, and enhanced population of butyrate-producing bacteria and cellulolytic bacteria F. succinogenes.

The purpose of this study is to analyze the effects of the health center hospital on the health service utilization pattern of the rural population in a county. Two field studies had been conducted in Yonchon County, Kyunggi Province, on February 1989 and on August 1991 before and after the establishment of the Yonchon health center hospital. This study revealed that Yonchon health center hospital occupied 7.3% of total outpatient visits and 16.8% of hospitalization of the county population and the self-sufficient rate of the outpatient visit and hospitalization of Yonchon County between two field studies increased by 1.7% and 20.9% each. Yonchon health center hospital contributed to the growth of the public health sector but it weakened the role of health sub-centers. For the efficient health service utilization of the population in that County, more investment to health center hospital would be needed and the primary health activities of the health subcenter should be enforced.

본 연구에서는 시멘트공업이 발달함에 따라 지역에 어떤 영향을 미쳤는지를 알기 위하여 매포지역을 사례로 하여 종합적으로 고찰하였으며, 연구결과를 요약하면 다음과 같 다. 1) 연구지역은 1960년대에 세개의 시멘트공장이 건설되면서 노동자, 기술자들이 대량으 로 유입되어 폭발적인 인구증가를 나타냈으며 1970년대에는 시설확장으로 고용기회가 많이 늘어나 인구가 더욱 집중하게 되었다. 그러나 1980년대에는 오랜 경험과 기술 출적으로 인 한 각종 기계의 자동화와 대형화로 노동력이 대체되어 종업원의 수가 그 이전보다 줄어들고 인구 역시 감소되고 있다. 2) 시멘트공업이 발달하면서 시멘트공장이 입지한 곳과 그 인접 지역은 공장사택으로 인하여 비농가율이 높게 나타난다. 그리고 공장부지, 광상의 확대로 농 경지는 점점 감소되고 시멘트공업과 비교적 관계없는 농촌지역들은 농업적 토지이용이 크게 달라지지 않았다. 또 이 지역은 분진이 가장 심각한 공해문제를 야기한다.

About 83% of the total population of Lao PDR lives in rural areas. People living near forest are highly dependent on the forest resources closed to their villages. Especially non-timber forest products (NTFPs) provide a wide range of subsistence needs and are the main source of their cash income. They also make a significant contribution to the country economy. The annual export value of NTFPs is considerably high. 708 edible NTFP species (238 edible plants and 470 animals) have been recorded so far, and about 400 plants have been reported and used as medicinal plants by Lao people. One hundred NTFP species are considered as commercial forest products. The striking trend in NTFP resources is the decline of some commercial species due to increased demand on them for commercialization, and the loss of forest by rapid population growth. To sustainablely manage the NTFPs resources, a number of new management systems are under development and support in progress by the government.

Objectives This study aimed to evaluate the risk factors associated with depression and suicidal ideation in a rural population. Methods A survey was conducted with 543 farmers from Chungcheongnam-do Province using the Center for Epidemiologic Studies Depression Scale (CES-D) for depression, Lubben Social Network Scale (LSNS) for social support, Swedish Q16 for neurotoxicity symptoms and a survey tool for farmer's syndrome. Results After adjusting for socioeconomic factors using logistic regression analysis, poor self-rated health, low social support and neurotoxicity were positively associated with the risk of depression (odds ratio [OR], 15.96; 95% confidence interval [CI], 3.11 to 81.97; OR, 3.14; 95% CI, 1.26 to 7.82; and OR, 3.68; 95% CI, 1.08 to 12.57, respectively). The risk of suicidal ideation significantly increased with low social support, neurotoxicity and farmer's syndrome (OR, 2.28; 95% CI, 1.18 to 4.40; OR, 6.17; 95% CI, 2.85 to 13.34; and OR, 3.70; 95% CI, 1.51 to 9.07, respectively). Conclusions Given the overall results of this study, there is a need to establish programs which can improve the health and social relationships of farmers. Also, when farmers have neurological symptoms from pesticide exposure and characteristic symptoms of farmer's syndrome, a monitoring system for depression and suicide must be made available.
