The study is a comparative analysis of the differences in economic activities of two rural villages near the city. It is the general notion that rural villages near large cities lose the characteristics of traditional rural villages and change the areas with urban characteristics due to the influence of urbanization. The survey also showed that Munho 4-ri and Jeongbae 1-ri in Gyeonggi-do have urban characteristics, such as population growth, agricultural activity reduction and non-agricultural activity increase, and community activity reduction. However, they also found that there were important differences in the future development patterns of the two villages. In other words, the reasons and purposes of migration of people moving to the two villages, the differences in the system of economic activity in the villages, and the differences in community cooperation are emerging. Therefore, the study shows that policies to develop rural villages near cities need to be implemented differently based on the characteristics of those villages.

The purpose of this study is to suggest the possibility of complexity use these facilities for elderly welfare facility or public health facility and community center in rural. For this purpose this article researched into elderly welfare facilities, public health facilities and social welfare centers. And we studied of village community center, life pattern in old people in rural. With a rapidly increase in population of older people in rural, there is a great demand for the construction of complexes facilities. Particularly, there was highly demand for the public health facilities and the welfare programme of physiotherapy facilities on village community center in rural. However, there is not a intersection of space composition and specification function between elderly welfare facilities and public healthcare facilities and community welfare centers in this time. Accordingly, in the future plan for community center in rural, it is necessary to consider integration with public health facility. And it is necessary to compose the community center in consideration of the spatial organization of complexity as a possibility of community welfare activities.

Global food prices have skyrocketed due to international uncertainties such as COVID-19 and the Russian-Ukrainian War. In this context, the importance of rural areas as a source of food production is also rapidly increasing. However, the issue of regional extinction is emerging as Korea faces the world's lowest fertility rate and fastest aging population. Also, rural areas are losing their population more rapidly than large cities. Therefore, this study aims to analyze the factors that can encourage the influx of fishermen to prevent the disappearance of these fishing villages. As a result of the analysis, in order to prevent the disappearance of fishing villages, among the infrastructure, natural environment, and residential environment variables, the ratio of aged housing related to quality of life, culture and amenities coefficients were found to have a greater impact than other variables. Based on these results, it is judged that it is necessary to establish a sufficient level of infrastructure in fishing villages and to prioritize policies for improving the residential environment.

Cervical cancer continues to be a serious public health problem in the developing world, including China. Because of its large population with geographical and socioeconomic inequities, China has a high burden of cervical cancer and important disparities among different regions. In this review, we first present an overview of the cervical cancer incidence and mortality over time, and focus on diversity and disparity in access to care for various subpopulations across geographical regions and socioeconomic strata in China. Then, we describe population-based cervical cancer screening in China, and in particular implementation of the National Cervical Cancer Screening Program in Rural Areas (NACCSPRA) and the challenges that this program faces. These include low screening coverage, shortage of qualified health care personnel and limited funds. To improve prevention of cervical cancer and obtain better cancer outcomes, the Chinese government needs to urgently consider the following key factors: reducing disparities in health care access, collecting accurate and broadly representative data in cancer registries, expanding target population size and increasing allocation of government funding for training of personnel, improving health education for women, enhancing quality control of screening services and improving a system to increase follow up for women with positive results.

We intend to improve the sustainability of rural villages by investigating the element technologies and platforms necessary for building smart villages. There are so many investment smart city platforms and solutions in many cities. but there are relatively few investments in rural or small cities. This situation can not only increase the urban problem due to the increase of population to the city, but also deepen the digital gap of citizens. So far, studies on smart village have been investigated in fragments. We will examine the cases applied to smart village as a whole and study the open smart village platform that analyzes the overall data storage and management of the village after the smart village was finally established. First, we will look at the overseas trends of smart village and second, we will study the smart village platform that efficiently manages smart village through the technology necessary for smart village.

Southern blight, caused by the soil-borne fungus Sclerotium rolfsii, is a serious disease that affects many economically important crops. In this study, we selected Bacillus subtilis GJ6-14, from a total of 260 strains, to control Southern blight in pepper plants. In both seedling and plant tests, GJ6-14 significantly suppressed disease incidence and severity compared to control, furthermore, GJ6-14 demonstrated efficient colonization in the rhizosphere by maintaining the population from log 5.41 to log 3.92 in the pathogen-inoculated plants, indicating its potential as a biocontrol agent. Molecular analysis revealed up-regulation of defense-related genes, such as a 7.6-fold increase in LOX1 and 15.5-fold increase in PR1, at 72 hr after inoculation of S. rolfsii in GJ6-14-treated plants, suggesting activation of plant defense mechanisms. Overall, our findings highlight the promising role of B. subtilis GJ6-14 as a potential biocontrol agent in sustainable management of Southern blight in pepper plants.

Linkage disequilibrium between markers or genetic variants underlying interesting traits affects many genomic methodologies. In many genomic methodologies, the effective population size ($N_e$) is important to assess the genetic diversity of animal populations. In this study, dairy cattle were genotyped using the Illumina BoviveHD Genotyping BeadChips for over 777,000 SNPs located across all autosomes, mitochondria and sex chromosomes, and 70,000 autosomal SNPs were selected randomly for the final analysis. We characterized more accurate linkage disequilibrium in a sample of 96 dairy cattle producing milk in Korea. Estimated linkage disequilibrium was relatively high between closely linked markers (>0.6 at 10 kb) and decreased with increasing distance. Using formulae that related the expected linkage disequilibrium to $N_e$, and assuming a constant actual population size, $N_e$ was estimated to be approximately 122 in this population. Historical $N_e$, calculated assuming linear population growth, was suggestive of a rapid increase $N_e$ over the past 10 generations, and increased slowly thereafter. Additionally, we corrected the genomic relationship structure per chromosome in calculating $r^2$ and estimated $N_e$. The observed $N_e$ based on $r^2$ corrected by genomics relationship structure can be rationalized using current knowledge of the history of the dairy cattle breeds producing milk in Korea.

In this study, we visualized the regional migration in Korea from 2001 to 2015 using the Chord diagram which can represents amount of migration and flows at the same time. In addition, we constructed a migration network and analyzed the degree centrality of each region for identifying the main regions linking to various regions. In 2001~2005, most of population moved into Geonggi from various regions. However, the capital function was transferred to Sejong in 2011~2015, and population moving into Sejong and Chungnam was increased significantly. The main outflow of population in migration network were shown at the regions in Jeonbuk and Gyeongbuk province in 2001~2004, and recently the regions in Gyeongnam, Gyeonggi, and Seoul were identified as the main nodes in terms of outflow of population. We also focused on migration in rural area through degree centrality, and cord diagram in Chungnam, Jeonbuk, and Jeonnam where include the representative crop area. In 2015. there was the significant increase of migration from Gyeonggi to Chungnam, and internal migration within Jeonbuk increased rather than cross-border migration. In addition, migration from Jeonam to capital area decreased in 2015 but migration among cities within Jeonman increased. In particular, Yesan-gun showed the significant migration to other cities in Jeonnam. Population is necessary to develop community and sustain economic growth in rural regions. Therefore, migration is important for the transfer of manpower. The strength of this study is to approach the temporal change of migration from the viewpoint on quantitative and structural characteristics.

본 연구는 인삼재배지 포장에서 부엽토와 돈분퇴비 시용이 토양생물에 미치는 영향을 조사하고자, 토양미생물, 선충, 응애 등 미소동물의 군집과 개체밀도의 변화를 관찰하였다. 토양 미생물 군락 조성과 생태를 조사하기 위하여 인지질지방산을 추출하여 지표지방산으로 분석한 결과 세균, 곰팡이, 방선균의 상대밀도는 차이가 없었다. 부엽토 처리구에서 환경스트레스 지표인 포화지방산/단불포화지방산 비율과 Cyclopropyl 지방산/전구체 지방산 비율이 높게 나타났으며, 호기성/혐기성균 비율이 낮았던 것은 유기물의 분해속도가 느리다는 것을 시사한다. 돈분퇴비 처리구에서 내생균근균인 VAM의 상대밀도 증가는 pH 증가의 영향으로 보이지만, 유기물 증가에도 불구하고 그램음성균/그램양성균 비율과 스트레스 지표가 대조구와 차이가 없었던 것은 EC나 pH 증가 등으로 인한 토양의 이화학성 변화에 의한 결과로 보인다. 돈분퇴비 시용구에서 선충의 개체밀도는 증가하였지만, 날개응애류의 개체밀도는 감소하였다. 부엽토 또는 돈분퇴비의 시용에도 불구하고 토양동물의 개체밀도는 일반 농경지와 비교할 때 매우 낮은 수준으로 나타났으며, 개간지의 경우 장기간의 예정지 관리를 통해 토양생물의 밀도를 높여 유기물의 분해효율을 증가시키는 과정이 필요할 것으로 판단된다.
