Researching the soil fungal community is important to understand the interaction between fungi and living plants. However, too few studies have examined the soil fungal community and their interactions with plants. Rhododendron mucronulatum, commonly known as Korean rosebay, is an important forest resource that has aesthetic, ecological, and potential pharmacological values. We used a pyrosequencing method to analyze the characteristics of fungal communities from R. mucronulatum soil samples from Biseul mountain county park, which is one of the famous places for large R. mucronulatum colonies in South Korea. We collected soil core samples in February and August at three sites in the Biseul Mountain County Park, taking into consideration the regional and seasonal conditions. We obtained 454,157 validated reads after pyrosequencing all six samples. The fungal communities from the first observation spot in August had the richest species diversity among the samples. Basidiomycota, Ascomycota, and Mortierellomycota were major phyla in the samples. Agaricales_f, Mortierellaceae, and Clavariaceae were major families in the samples. The genus Mortierella was the most dominant in all six samples. Overall, 19 genera could be associated with R. mucronulatum. Sample 1 had 109 genera in sample 1, sample 2 had 111 genera, and sample 3 had 112 genera that were uniquely identified. The samples collected in August had 28 identified genera, that existed only in summer samples, indicating a weather effect. This study can be used as basic research to understand the relationship between soil fungi and plants.

A new vegetable peanut cultivar "Charmwon" (Arachis hypogaea ssp. fastigiata.L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang 2006. It was developed from the cross between the disease resistant cultivar "HYQ(CG)S-10" and the high-yielding cultivar "Sinkwang". "Charmwon" which has been classified as Shinpung plant type is less branch number with early flowering and ellipse-shaped large kernel. Each pod which showed very shallow constriction had two grains with red testa and 100 seed weight was 90g in the regional yield trials (RYT). This variety also showed higher free sugar and protein contents in seed quality, and had more resistant to early and late leaf spot diseases compared with check one. In the regional yield trials "Charmwon" was out-yielded than check variety by 18% with 8.93 ton/ha for fresh pod and by 4% with 3.95 ton/ha for grain.

The purpose of this study is to explore the improvement method of the emergency safety system as a social protection scheme for the elderly living alone with severe disabilities. The study was conducted by randomly choosing three regions in the metropolitan area (Jongno-gu, Seoul), the small-medium city (Yongin-si, Gyeonggi-do) and the rural area (Geochang-gun, Gyeongsangnam-do) among 17 cities and counties nationwide. The study method is based on the interview form of the structured questionnaires with city officials, county officials, and center operators. According to the results of the interview analysis, it was recognized that there was a need for an emergency safety system for the elderly living alone with severe disabilities. In spite of this necessity, there were problems about publicity for the discovery of victims of the blind spot in welfare, about inconvenience due to frequent malfunctions of the emergency equipment, about insufficient awareness of the security of the emergency officials and about supply and demand of manpower for 24-hour monitoring service. In order to improve the effective operation of the emergency safety system, it was the most urgent issue to formulate the legislation for responding to the crisis management of the vulnerable. A suggestion of this study is to build a safety system in which one-stop service is provided for the realization of compact welfare through the establishment of a MOU for linkage with community organizations, the full inspection of emergency equipment to solve safety equipment malfunction problems and the manpower supplement for 24-hour monitoring.

This article considers the meaning of 'Zainichi (在日)' expressed in epic poem Niigata (1970) written by Korean-Japanese poet Kim Shi Jong. Kim sets two points in his creation of poetry. One is summer of liberation released from Japanese colonial domination in 1945. The other is Japan where he lives as a Korean-Japanese. These two points have made him think about the meaning of living in post-colonial era and the national division of Korea, his home country. His thought like this is well expressed in his epic Niigata. Niigata was written in 1959 when the ship returning to North Korea departed from Niigata of Japan. However, Kim couldn't return to his home country at that time. He stowed away from South Korea to Japan in 1949. He participated in antigovernment activities occurred in Jeju Island to block the national division between the south and the north after the liberation in 1945, the so-called 4.3 incident. Besides, he was having conflict with the organization of North Korea at that time because it required a doctrinaire belief and creation in Korean. Kim was writing poems in Japanese and pursued the life of existence as a Korean-Japanese. Therefore, he decided to remain in Japan instead of returning to North Korea. Of course, he could not return to South Korea because he was a refugee. Kim imagined in Niigata, the place located in an extension of the 38th parallel and the spot of national division. He could not cross the division line when he was in his home country, but he could do it in Niigata through imagination. The life as a Korean-Japanese makes it possible. 'Zainichi', which means living in Japan, has been recognized as a worse situation compared to living in Korea. However, Kim changed his way of thinking. Zainichi can embrace South Korea, North Korea, and Japan. This is the very reason why he lives there as a Korean-Japanese. His thought like this is well expressed by symbolic representations and metamorphose as well as the imagination of spatial extension.

Recently old stone walls were designated as registered cultural properties that meant an extension of categories about cultural properties from a spot area to whole area. Moreover given the changing situation of residential pattern, which is due to rapid social change, this designation can be seen as a significant measure to keep as intact as possible traditional landscapes in agricultural and fishing villages. In this paper, I analyze the symbol system and meaning of old stone walls and attempt to pick out the cultural elements which are related to them. These days we have made efforts to various aspects for which make traditional cultural resources into cultural contents. But many studies had done before emphasized aspects for beauty only. Especially existing studies about an old stone wall was mainly focused on architectural interpretation and tourist route. So we need to build a plot around oral research and need a creative approach for sharing with tourists. Cultural contents combine the original form, potential and capabilities with media by detecting original form of culture and finding out the worth and meaning. In this paper examined the probability of using by investigating a stone wall in Sang-hak Village that is related with recovering of places to live in contemporary society and finding cultural contents. I suggest more creative ways to make cultural properties into tourist resources by considering the possibilities of place marketing using storytelling, based on an analysis of data gathered.

This study examined the effectiveness of wind corridor construction by analyzing the thermal environment, cold air generation, ventilation, and geographical characteristics to improve urban thermal environment and establish the basis for specialized strategy in Changwon-si, Gyeongsangnam-do. Using spatial analysis and remote sensing techniques, surface temperature, land cover and land use, wind field, and slope were measured and through this, a wind corridor analysis model was constructed. As a result of the analysis as of 2020, Changwon-si generally has land cover characteristics that are advantageous for the generation of cold air, but the temperature in most urban areas is the highest, and the temperature in areas such as north Changwon area, Jinbukmyeon, Ung-dong, and Ungcheon-dong are relatively high. There was a typical trend of high average wind speed in mountain regions and low average wind speed in urban areas. Accordingly, the north Changwon area, the former Changwon downtown area, the Hogye-ri and Pyeongseong-ri areas, and the Changpo Bay area are derived as vulnerable areas to thermal environment, and various measures to reduce temperature and improve air quality that the inflow of cold air into the area considering the characteristics of each area and securing wind ventilation between the surrounding mountains, reservoirs, and park areas were proposed.

"Seonweon Bogam" was made for the purpose of delivering information on the tomb of members of the royal family of the Joseon Dynasty. Accordingly, it covered all of Sando making a pictorial expression of the tomb. But its value has been doubted as it is roughly expressed and different from the picture of the actual scene. But "Seonweon Bogam" is the only book that covers Sando of all the kings of the Joseon Dynasty but contains the elements making it possible to estimate the possibility that the original Sando might be used in making Sando. Accordingly, it is a high time to make an in-deep study of this. This study attempted to investigate Sando included in "Seonweon Bogam" with a focus on the expressive style. For this purpose, it sought to analyze seven elements such as the exposure, the legend, locational information, direction, waterway and road, expression on water and Fengshui(風水) terminology. As a result, the following conclusion was drawn: Sando concerning the tombs of members of the Joseon Dynasty was continually made. It was made in two ways such as the way of drawing the scene on spot and the way of imitating the existing made material. And it could be estimated that there is a possibility that Sando of "Seonweon Bogam" might be copied by the figure with only a little expertise about Sando but on the basis of several materials about the existing Sando of the royal family.

Background: The purpose of this study is to analyze whether there is a change in patterns of medical use among those likely to be converted their health insurance qualifications when the family support rule is alleviated. There is no empirical analysis that converting health insurance qualification will affect the increase in medical use. Methods: For analysis, data were extracted from the national health insurance eligibility and medical care database. To identify analysis targets similar to that of medical aids' characteristics among health insurance coverage, we compared income, property level, and medical use patterns through basic statistical analysis and used a difference-in-difference (DID) analysis to estimate the net effect of changes in medical use following the change of qualifications. Results: The main results are as follows. The results show that those who are under the 5% income group (1st income group) of health insurance coverage are the most similar to the medical aids group. DID analysis shows that changes in the medical use of people who maintain their national insurance qualification and who are not. As a results, the number of hospitalized days of converting group was reduced by 3.5 days while outpatient days were increased by 1.8 days. Conclusion: As a result, there was not much difference in the patterns of medical use for the under 5% income group who are likely to be eligible for expanded medical aids when the family support rule is alleviated. In addition, more than 30% of them are in arrears with their health insurance premiums, causing inconvenience in using medical services. These findings suggest the need of abolishing the criteria obligated to support family, and great efforts should be made to contribute to non-paid poor and remove their medical blind spot.

Rice is responsible for the stable crop of 3 billion people worldwide, about half of Asian depends on it, and rice is grown in more than 100 countries. Rice diseases can lead to devastating economic loss by decreasing yield production, disturbing a stable food supply and demand chain. The most commonly used method to control rice disease is chemical control. However, misuse of chemical control can cause environmental pollution, residual toxicity, and the emergence of chemical-resistant pathogens, the deterioration of soil quality, and the destruction of biodiversity. In order to control rice diseases, research on alternative biocontrol is actively pursued including microorganism-oriented biocontrol agents. Microbial agents control plant disease through competition with and antibiotic effects and parasitism against plant pathogens. Microorganisms isolated from the rice rhizosphere are studied comprehensively as biocontrol agents against rice pathogens. Bacillus sp., Pseudomonas sp., and Trichoderma sp. were reported to control rice diseases, such as blast, sheath blight, bacterial leaf blight, brown spot, and bakanae diseases. Here we reviewed the microorganisms that are studied as biocontrol agents against rice diseases.
