The purpose of this study was to analyze the loss of open space of schools in Ulaanbaatar city and found out main causes of the conversion trend of open space to suggest alternatives. 76 designated sites were selected from 118 public schools within 6 districts of Ulaanbaatar city. These 76 schools were eligible for analysis of the open space change between 2005 and 2015 with Google Earth Pro. The results showed that $175,048m^2$ open space was developed and two dominant types of open space conversion were found; 1) constructions of school facilities such as soccer field, extended school buildings, parking lot, sidewalk, and square, and 2) constructions of apartment buildings and service facilities such as community center, pedestrian, sports facilities, and parking lot. Apartment complex development has commonly happened in all districts and caused bigger open space loss than other types of development. Chingeltei district is located in the center of Ulaanbaatar city, and schools in this district lost the biggest open space, $50,036m^2$/35.24% over 10 years. The rate of open space loss seemed to be related to the distance from the urban center and open space loss was an ongoing event in Ulaanbaatar city. This trend would not be improved without a strong regulation, so, in this study, making strict regulations that prevent conversions of open space were suggested to conserve open space in Ulaanbaatar city.

In this study, the landscape characteristics and culture of the sacred Dangsan forests at Dongnae-ri, Seonae-ri, Namnae-ri, Pyeongchon-ri and Gyochon-ri were investigated. And the potential for registration in the World Heritage List has been discussed by linking the Dangsan forests at the five sites. Dangsan forest, a traditional village forests of rural Korea is a representative cultural heritage with a history of more than several hundred years of Dangsan ritual. The Dangsan forests in the neighborhood of Naganeuoseong have retained the landscape of town fortress during Choseon Dynasty and the Dangsan ritual as a living culture. The three villages inside Naganeuoseong have kept their Upper Dang, Middle Dang and Lower Dang. There were 21 old trees in total; Zelkova serrata (2), Celtis sinensis (7), Aphananthe aspera (5) trees, Carpinus tschonoskii (2) and Ginkgo biloba (3). The three Dangsan trees and an old Aphananthe aspera, known as to be planted by the Admiral Yi Sun-sin were recognized. The two villages located outside of village fortress also have kept their Dangsan ritual. It is important whether the sites possesses authenticity in order to be listed in the World Heritage. The Dangsan forests in the neighborhood of Naganeuoseong have been verified for the authenticity, which should be focused. The places need to be clarified for their landscape features formed as a Dangsan forest, and sustainable protection and management plans are to be devised.
This study evaluated properties and items for selecting on a forest healing village. In order to assign a weight value-between factors, this study was conducted the primary survey first and then the secondary survey for measuring the importance of items. Experts'surveys were conducted on 3 items on level 1, 9 items on level 2, 35 items on level 3 with use of AHP technique. In level 1, the main analysis result was that physical resource properties(0.387) indicated the highest importance. in level 2, healing resources of physical properties(0.402), community participation of human resource properties(0.425), and business competency in part of vision(-.438) showed the highest importance. The analysis result of 35 items on level 3 was that in physical resources properties, securing public land in the village(0.220), possessing recreation space(0.440) and resources available for link with healing(0.413) showed the highest importance. In part of human resources properties, the average age of residents(0.465), commitment to the promotion of the villagers(0.367) and support of local leaders(0.318) showed the highest importance. Adequacy of development plan(0.274), forest work experience-related(0.293), and building profit sharing system(0.282) were also evaluated to have a relatively high importance.

Background: Ginseng is one of the well-known medicinal plants, exhibiting diverse medicinal effects. Its roots possess anticancer and antiaging properties and are being used in the medical systems of East Asian countries. It is grown in low-light and low-temperature conditions, and its growth is strongly inhibited at temperatures above $25^{\circ}C$. However, the molecular responses of ginseng to heat stress are currently poorly understood, especially at the protein level. Methods: We used a shotgun proteomics approach to investigate the effect of heat stress on ginseng leaves. We monitored their photosynthetic efficiency to confirm physiological responses to a high-temperature stress. Results: The results showed a reduction in photosynthetic efficiency on heat treatment ($35^{\circ}C$) starting at 48 h. Label-free quantitative proteome analysis led to the identification of 3,332 proteins, of which 847 were differentially modulated in response to heat stress. The MapMan analysis showed that the proteins with increased abundance were mainly associated with antioxidant and translation-regulating activities, whereas the proteins related to the receptor and structural-binding activities exhibited decreased abundance. Several other proteins including chaperones, G-proteins, calcium-signaling proteins, transcription factors, and transfer/carrier proteins were specifically downregulated. Conclusion: These results increase our understanding of heat stress responses in the leaves of ginseng at the protein level, for the first time providing a resource for the scientific community.

This study performed quality study to examine cognition and experience as it is about husband role of wife's perception in rural multicultural family. Specifically the results of in-depth interviews with 13 females in rural multicultural family was analyzed through phenomenological method. The results were as followings: first, wife's cognition about husband role in rural multicultural family, they were 'nice and warm man', 'no special thought', 'clean and cool looking man', 'man without straitening wife', 'husband taking care of housekeeping', 'having independent family' and 'strong responsibility to children'. Females in rural multicultural family did not deeply think about husband's role at international marriage, but it could be known that vague longing for rich country, Korea by Korean wave and its expectation continued to expectation on husband. Second, they were 'good-tempered and nice to me', 'adjust to me', 'irresponsibility and apathy', 'cannot lean to him', 'no housekeeping', 'intermediate role between his family', 'more taking care of children, parents and relatives', 'drink, gambling and violence'. The experience of husband role was little different from cognition of husband role by females in rural mulitcultural family.

This study attempts to elicit the organizational strategy and operational elements of community-based agricultural management bodies as new main farm management. We analyzed the newest discussion trend, cooperated community management, between Republic of Korea and Japan based on theory of organizing regional agriculture, and also researched on the organization management and business management about cooperated management of community. In this study, the main conclusion of the organizational strategy and operational elements of community-based agricultural management bodies are as following. i) The community-based agricultural management bodies is the cooperation managed individual agriculture resources as joint stock for purposing compound goal, an expansion agricultural income, maintenance farm productivity and rural societies. ii) The domain of cooperative management focus on secondary and tertiary industry like food process, farm produce distribution, rural experience more than farm produce production. The study suggest business promotion system of village unit farmers groups, element of organization management as executive decision organization, business management, operating factor for each steps and management element of cooperation farm working. iii) The policy direction for invigoration community-based agricultural management bodies is to make facilitation for each steps instead of standardized support.
Objectives: This study aimed to develop dietary education textbooks for elementary school students by focusing on the three core values of environment, health and gratitude from the National Food Education Plan. Methods: The contents of textbooks and teacher's guidebooks were developed with brainstorming of the authors as well as consultation with experts and by considering not only the three core values of environment, health, and gratitude, but also the performance indicators of the 2nd National Food Education Plan and the key competencies and creative convergence approach of the 2015 revised national curriculum. Results: A total of 12 different dietary education textbooks named 'Good Dietary Life Guide' and the teachers' guidebooks from the first to the sixth grade of elementary school were developed. The textbooks were fundamentally developed connecting the three core values, the outcome indices of the 2nd National Food Education Plan and the key competences of the 2015 revised national curriculum. Various educational activities such as thinking, debate, writing, cooperative learning, experience, practice were included to promote students' participation. These books could be utilized in every field of dietary education targeting elementary students such as creative experiential activity, convergent classes (integrated subjects, Practical arts, Social studies, Science, Moral education and Korean), after school classes, rural experience, general agricultural education, after-school child care services and community child care centers. Conclusions: The continuous and repetitive use of the textbooks from the first to the sixth grade would contribute to the improvement of food habits and the personalities of elementary school students, and consequently make the students grow up as healthy citizens.

Objective: As laying hens become aged, laying performance and egg quality are generally impaired. One of the practical methods to rejuvenate production and egg quality of aged laying hens with decreasing productivity is a forced molting. However, the changes in intestinal microbiota after forced molting of aged hens are not clearly known. The aim of the present study was to analyze the changes in excreta bacterial communities after forced molting of aged laying hens. Methods: A total of one hundred 66-wk-old Hy-Line Brown laying hens were induced to molt by a 2-d water removal and an 11-d fasting until egg production completely ceased. The excreta samples of 16 hens with similar body weight were collected before and immediately after molting. Excreta bacterial communities were analyzed by high-throughput sequencing of bacterial 16S rRNA genes. Results: Bacteroidetes, Firmicutes, and Proteobacteria were the three major bacterial phyla in pre-molting and immediate post-molting hens, accounting for more than 98.0%. Lactobacillus genus had relatively high abundance in both group, but decreased by molting (62.3% in premolting and 24.9% in post-molting hens). Moreover, pathogenic bacteria such as Enterococcus cecorum and Escherichia coli were more abundant in immediate post-molting hens than in pre-molting hens. Forced molting influenced the alpha diversity, with higher Chao1 (p = 0.012), phylogenetic diversity whole tree (p = 0.014), observed operational taxonomic unit indices (p = 0.006), and Simpson indices (p<0.001), which indicated that forced molting increased excreta bacterial richness of aged laying hens. Conclusion: This study improves the current knowledge of bacterial community alterations in the excreta by forced molting in aged laying hens, which can provide increasing opportunity to develop novel dietary and management skills for improving the gastrointestinal health of aged laying hens after molting.

The scientific information between microbial community and chemical properties of reclaimed tidal soil is not enough to understand the land reclamation process. This study was conducted to investigate the relation between chemical properties and microbial activities of soils from reclaimed tidal lands located at south-western coastal area (42 samples from Goheuong, Samsan, Bojun, Kunnae, Hwaong and Yeongsangang sites). Most of the reclaimed soils showed chemical characteristics as salinity soil based on EC. Only $Na^+$ in exchangeable cation was dependent on EC of reclaimed soil, whereas other cations such as $K^+$, $Ca^{2+}$, and $Mg^{2+}$ were independent on EC. The mesophilic bacteria decreased with an increase in EC of soil. Microbial population increased with soil organic content in the range of $0{\sim}10g\;kg^{-1}$ and dehydrogenase activity less than $100{\mu}g-TPF\;g^{-1}h^{-1}$. Microbial population of soils from reclaimed tidal lands was closely related to the microbial community containing hydrolytic enzyme activities of cellulase, amylase, protease, and lipase.

Five hundred seventeen farmers(214 males and 303 females), over age 30 and living in Suh San County, Unsan township, were examined to determine the prevalence of peasants syndrome. Using the health interview questionnaire, the farmers were asked whether they had any of eight subjective symptoms during the past one month before the survey, October 1979. Those symptoms reported were scored based on a pre-determined point system. The farmers with high symptom scores(7 points or more) were further examined by the liver function test. In addition, all the sample(517 cases) were subjected to the examination of urinalysis and blood pressure. The liver function test is also undertaken for those farmers with high symptome scores(7 points or more) and those with abnormal findings in urinalysis and blood pressure. The results are summarized below: 1) 156 out of 517 farmers(30.2%) have had seven points or more of the symptom scores. Among the eight major symptoms, 72% of the farmers complained of lumbago. 2) The prevalence of peasant's syndrome were higher among females and the older age group. The symptom scores of this syndrome were slightly higher among women who have had many children (e. g. 4 or more). 3) The prevalence of peasant's syndrome was also related to the level of one's education-the lower education groups were found to have higher symptom scores of this syndrome. This may be due to the fact that the lower education groups are more exposed to manual labor. 4) The points of the peasants syndrome were higher in hypertensive farmers and those with abnormal findings of urinaly sis. 5) It was reported, in Japan, that those with high scores of the syndrome are more likely to have an abnormal findings in the liver function test. However, in this study it was observed that there was no significant difference between those with high scores of the syndrome (7 points or more) and those with low score of the syndrome(6 points or less) in the prevalence of abnormal liver function. As this study indicates that the point system given for the peasant's syndrome is closely related to the high bleod pressure and abnormal urinalysis(and to some extent to the abnormal liver function), there is a need to study peasant's syndrome more extensively. Such an effort will serve to detect varonic disease conditions among farmer's towards better management of farmer's health, which is vitally important for rural development in Korea.
