The elementary schools which have played the role as core institution of farming and fishing area and the central of community are either unionized nor abolished. These appearances are showed from not only certain area but all throughout the nation. This is to investigate the abolition of elementary schools and the practical use device through the conditions of elementary schools in Chonnam area. Such problems like school carrying out or schooling course and teacher supply and demand outbreaks in the areas of school attendance population rapidly decrease. These kind of problems should be solved by linked to true character of local area, maintenance & preservation of property value, balanced expansion of the country instead of simple school attendance population decrease and abolition of school. The practical device for rapidly coming school abolition and many related problems are urgently needed. And to solve all these kind of problums, First, enough examinations before the fact and communication & agreement with local residents will be needed. Second, basic dierction of device for usage of school after abolition school should be selected.

This study was conducted to investigate the effects of different sanitizers and contact times on storage quality and microbial growth in fresh-cut broccoli. Fresh broccoli samples were cut into small pieces, washed each for 90 s and 180 s in normal tap water (TW), $100\;{\mu}/l$ chlorinated water (CL, pH 7), electrolyzed water (EW, pH 7.2) containing $100\;{\mu}/l$ free chlorine, or $2\;{\mu}/l$ ozonated water ($O_3$). Then, samples were packaged in 30-${\mu}m$ polyethylene bags and stored at $5^{\circ}C$ for 9 days. No significant differences were observed in gas composition and color parameters ($L^*$, $a^*$, $b^*$, and hue angle) among different sanitizers with contact times. No off-odor was detected during the storage. A longer contact time was not effective in reducing microbial population, except with $O_3$ washing. $O_3$ with 90 s was not much effective in reducing microbial population compared with Cl or EW. However, samples washed with $O_3$ for 180 s observed the lowest numbers of total aerobic and coliform plate counts. The result suggested that, a longer contact time of ozone can be used as a potential sanitizer to maintain the microbial quality and safety of fresh-cut broccoli.

The purpose of this study is to investigate the concept, the necessity, and the increase of popularity of multi-habitation, a new life style in which inhabitants in urban areas reside in primarily condominiums during weekdays and retreat to dwellings in rural areas on the weekends. This paper also focuses on finding implication messages from analyzing the demand of multi-habitation in a survey which was conducted for 735 people who live in Seoul and the surrounding metropolitan areas in July 2009. Analysis of literature shows that based on five aspects (population structure, social economy, lifestyle, tourism, and housing market) this dynamic lifestyle, multi-habitation, is believed to be common in South Korea, and may increase in popularity in the near future. The results of the survey illustrate that the respondents show high interest in multi-habitation, and their most preferred locations are the green areas around the Seoul metropolitan area, which are one to two hours away by car. Moreover, regarding the participants' preferences in rural areas they were classified into three groups; those who want to reside in a nature environment, those who want to reside near family and in a close community, and those who want to reside in an environment that has essential facilities and easy accessibility.

The paraoxonase (E. C. 3.1.1.2) is a major enzyme to detoxicate the organophosphorus and carbamate which are the most widely used as the agricultural spraying insecticides. To investgate the distributions of plasma paraoxonase activity and the factors affecting the enzyme activity, the plasmas of 945 Korean rural population were analysed with the modified Krisch's direct sphectrphotometry method. Three indices of the enzyme activity - basal activity, stimulated activity (by NaCl), % stimulation - were obtained from the analysis. Three indicies suggested unimodal distributions, so we couldn't identify the low activity group risk group to organophosphorus & carbamate insecticides poisoning. There is no significant relation between 3 actvity indicies and sex, age, or history of insecticide use (p>0.05). The basal activity and the stimulated activity have significant relationship and high coefficient of determination with the activities of their parents ($r^2$=0.30, 0.24 ; p<0.05), but the % stimulation does not ($r^2$=0.02 ; p<0.05). These results suggest that the activity of paraoxonase is determined mainly by the genetic factor.

Purpose: We examined tobacco use pattern and its correlates among older adults. Materials and Methods: We used data of 9,852 older adults (${\geq}60$ years) (men 47% mean age 68 years) collected by the United Nations Population Fund on Ageing from seven Indian states. Logistic regression analysis was used to assess the correlates of tobacco use. Results: Current use of any form of tobacco was reported by 27.8% (men 37.9%, women 18.8%); 9.2% reported only smoking tobacco, 16.9% smokeless tobacco only and 1.7% used both forms. Alcohol users (OR:5.20, 95% CI:4.06-6.66), men (OR:2.92, CI :2.71-3.47), those reporting lower income (OR:2.74, CI:2.16-3.46), rural residents (OR 1.34, CI 1.17-1.54) and lower castes (OR:1.29, CI:1.13-1.47) were more likely to use any form of tobacco compared to their counterparts. Conclusions: Tobacco cessation interventions are warranted in this population focusing on alcohol users, men, those from lower income, rural residents and those belonging to a lower caste.

This study provides an empirical analysis of location competition for demand maximization by central place theory among physicians in nonmetropolitan areas of Korea. The results show that the primary care physicians distribute themselves evenly from urban communities to rural communities. The subspecialists, however, cluster together in major cities rather than decentralize themselves in rural counties. This study establishes the three statistical models : Primary care physicians, subspecialist physicians, and total physicians. Two models of primary care physicians and total physicians have a strong significance in multiple regression analysis (p=-.0001). The primary care model explains approximately 45% of the variation and the total physicians model explains approximately 70% of the variation in physician/1,000 population ratios across national counties. The subspecialist physicians model analysze the tobit regreassion because of the left consored and truncated values(57 cases = 0). In all three models, analysis of the coefficiencts for physician centralization degrees in the 0- to 5- and 5- to 10-km rings around the core county reveals each a positive and negative association betwee these degrees and the physician/1,000 population ratios in the core county. Also, the results provide moderate evidence that the relationship between clinic physicians and community hospitals is competitive, and the relationship between clinic physicians and pharmaceutists is synergistic. This suggests that public policy makers and local self-governing bodies must take an active role to ensure procider availability and the regional health planning in all nonmetropolitan areas of Korea.

The study aims to explore the policy directions for young farmers within Korean agricultural context, particularly in Chung-nam Province. In order to accomplish this, young farmers were classified into three categories: successors, new farmers, potential farmers. The importance of young farmers is becoming more of a focus due to decline of population numbers in rural communities as well as the aging of agriculture population. In order to address these two problems, it is necessary to create and implement policy to support each category of young farmer. Rather than the current focus on nurturing young farmers as a labor force, the role of young farmers in maintaining local communities should be expanded in current agricultural system. The local community should provide appropriate conditions for young farmers in Chung-nam Province for the various purposes they have and the roles they fill. In conclusion, it is necessary to provide a 'space' where young farmers can meet base on the community. For this, the role of the community based intermediate support organization for the integrated support system is of great significance.

Background: Since the mid-20th century, the ways in which social networks and older adults' health are related have been widely studied. However, few studies investigate the relationship between self-rated health and position in a complete social network of one entire Korean rural village. This study highlights use of a complete network in health studies. Methods: Using the Korean Social Life and Health Project, the population-based data of adults aged 60 or older and their spouses in one myeon in Ganghwa island (Ganghwa-gun, Incheon, Korea), Incheon, Korea (with a 95% response rate), this study built a $1,012{\times}1,012$ complete social network matrix of the village. The data were collected from 2011 to 2012, and 731 older adults were analyzed. The ordered logistic models to predict self-rated health allowed us to examine social factors from socio-demographic to individual community activities, ego-centered network characteristics, and positions in a complete network. Results: From the network data, 5 network components were identified. Even after controlling for all other factors, if a respondent belonged to a segregated component, the probability that he or she reported good health dropped substantially. Additionally, high in-degree centrality was connected to greater self-rated health. Conclusion: This finding highlights the importance of social position not only from the respondents' point of view but also from the entire village's perspective. Even if a respondent maintained a large social network, when all of those social ties belonged to a segregated group in the village, the respondent's health suffered from this segregation.

Purpose: This study investigated the health literacy level of, the hypertension knowledge of, the self-management behaviors of, and the factors influencing self-management behaviors of the hypertensive elderly population residing in the urban and rural areas. Methods: Data were collected from November to December 2017 by the trained research staff. For two months, a total of 160 subjects in urban and rural areas who had been taking antihypertensive medications consented to participate in the project. 157 participants completed the survey. Results: The health literacy score of the hypertensive elderly subjects was at 48.38±8.13, the hypertension knowledge score at 8.90±2.01 points, and the self-management behaviors score at 52.96±8.08. The factor that influenced the self-management behaviors of the hypertensive elderly subjects the most was the health literacy, followed by the residential area, and the hypertension knowledge. Conclusion: The research findings suggest that a health promotion program for the hypertensive elderly population should be designed in consideration of the health literacy, the area of residence and the hypertension knowledge of the elderly.

Genetic analysis has great potential as a tool to differentiate between different species and breeds of livestock. In this study, the optimal combinations of single nucleotide polymorphism (SNP) markers for discriminating the Yeonsan Ogye chicken (Gallus gallus domesticus) breed were identified using high-density 600K SNP array data. In 3,904 individuals from 198 chicken breeds, SNP markers specific to the target population were discovered through a case-control genome-wide association study (GWAS) and filtered out based on the linkage disequilibrium blocks. Significant SNP markers were selected by feature selection applying two machine learning algorithms: Random Forest (RF) and AdaBoost (AB). Using a machine learning approach, the 38 (RF) and 43 (AB) optimal SNP marker combinations for the Yeonsan Ogye chicken population demonstrated 100% accuracy. Hence, the GWAS and machine learning models used in this study can be efficiently utilized to identify the optimal combination of markers for discriminating target populations using multiple SNP markers.
