The percentage of postnatal disabled people and elderly population is rapidly increased by the industrialization, and the improvement of medical technology. The disparity between the city and rural area is in the way to disabled people who need rehabilitation. To solve these problems, Community Based Rehabilitation(CBR) is suggested by WHO. In this study, at first, the CBR model considering the specific characteristics of AnSan City are presented. Secondly, the first, the second, and the third rehabilitation facilities in AnSan City are classified by the CBR model. Thirdly, the estimation of optimum space for physical therapy and occupational therapy at rehabilitation center and public health center are sugested, which are the second level rehabilitation facilities. There are some differences in the distribution of population between new and old area in AnSan City. In other words, the subject population of CBR program in old area is relatively higher than that of new area. So, the CBR program for AnSan City must reflect their regional characteristics. In this study, the therapeutic boundaries of second level rehabilitation facilities is decided through the survey of physical therapists and occupational therapists in general hospitals and nursing homes.

자연 및 기술재해에 빠르고 효과적으로 대응하기 위해서는 그 재해지역 내에 있는 인구수를 정확히 추정할 필요가 있다. 그러나 센서스 구역과 재해지역의 공간적 불일치 문제 때문에, 재해지역 내에 있는 인구수를 정확하게 추정할 때에는 구역단위 인구자료를 공간적으로 세분화할 필요가 있다. 본 논문은 센서스 블럭그룹 내의 인구를 개개의 화소로 세분화하기 위한 밀도 구분적 표면모델을 구현하고, 그 표면기반 공간적 세분화 모델의 성능을 통계적 및 가시적으로 평가한다. 표면기반 공간적 세분화 모델은 밀도 구분적 내삽법과 위성영상으르부터 추출된 토지이용 및 피복자료를 사용하며 지리정보시스템에서 구현되었다. 토지이용 및 피복자료는 밀도 구분적 내삽법에서 인구의 지리적 분포에 관한 추가정보를 제공했고, 토지이용 및 피복자료의 퍼센트에 기반을 둔 경험적 표본추출법과 지역가중법은 각 화소에 대한 밀도 구분적 가중치를 객관적으로 결정하기 위해서 사용되었다. 표면기반 공간적 세분화 모델은 애틀란타 대도시권의 밀도 구분적 인구표면을 만드는데 적용되었다. 그 밀도 구분적 인구표변의 정확도는 센서스 수치와의 비교를 통해서 RMSE와 수정 RMSE를 사용하면서 검증되었다. 또한, 각 센서스 트랙과 블럭그룹별 오차들은 퍼센트 오차지도들에 의해서 가시화 되었다. 분석결과에 따르면, 밀도 구분적 인구표면은 인구수의 정확한 추정치를 제시할 뿐만 아니라, 센서스 블록그룹 내의 인구의 상세한 공간분포를 보여 준다. 또한, 인구표면은 대개 교외 및 산림지역 그리고 도심지역에서 인구를 과소평가하거나 과대평가하는 경향이 있다는 것을 밝혀냈다.

Host shifting and host expansion of fungal plant pathogens increases the rate of emergence of new pathogens and the incidence of disease in various crops, which threaten global food security. Magnaporthe species cause serious disease in rice, namely rice blast disease, as well as in many alternative hosts, including wheat, barley, and millet. A severe outbreak of wheat blast due to Magnaporthe oryzae occurred recently in Bangladesh, after the fungus was introduced from South America, causing great loss of yield. This outbreak of wheat blast is of growing concern, because it might spread to adjacent wheat-producing areas. Therefore, it is important to understand the host range and population structure of M. oryzae and related species for determining the evolutionary relationships among Magnaporthe species and for managing blast disease in the field. Here, we collected isolates of M. oryzae and related species from various Poaceae species, including crops and weeds surrounding rice fields, in Korea and determined their phylogenetic relationships and host species specificity. Internal transcribed spacer-mediated phylogenetic analysis revealed that M. oryzae and related species are classified into four groups primarily including isolates from rice, crabgrass, millet and tall fescue. Based on pathogenicity assays, M. oryzae and related species can infect different Poaceae hosts and move among hosts, suggesting the potential for host shifting and host expansion in nature. These results provide important information on the diversification of M. oryzae and related species with a broad range of Poaceae as hosts in crop fields.

Rice is a staple food for nearly half of the world's population, with more than 10,000 rice varieties providing almost one-quarter of the global per capita dietary energy supply. Grain size, panicle size and branch number, grain number in a panicle are directly associated with rice productivity. Recently several genes which increase grain yield were identified through map-based cloning. Gn1a, Cytokinin oxidase, is a major grain number QTL and regulates grain number per panicle. Dep1 increases panicle branching and reduced rachis length. SCM2 (APO1) was identified by a QTL for culm strength and increased spikelet number. OsSPL16 (GW8) controls grain size and shape and then increases 1000-weight of seed. In here, to identify genotype of genes related to yield in 400 of rice germplasms possessed in National Institute of Crop Science, we had first chosen 4 of well-known genes related to yield; Gn1a, Dep1, SCM2, and OsSPL16. Among these germplasms, 195, 382, 165, and 353 of germplasms harbored the dominant type of Gn1a, Dep1, SCM2, and OsSPL16, respectively. We grouped these germplasms into a total of 10 groups using genotypes of Gn1a, Dep1, SCM2 and OsSPL16. Most rice germplasms belong to group 1, harbored Gn1a, dep1, gw8 and APO1, and group 10, harbored gn1a, Dep1, GW8 and apo1. Hanareum2 is the highest productive cultivar in Korea but do not have dominant type OsSPL16, so belong to group 1. On the other hand, in the case of Unkwang, belongs to group 10, which has dominant type of OsSPL16 but do not have the remaining genes. We can grasp the differences in rice germplasms through the Profiling of genes related to these grain yield, which will be useful for cross-breeding to integrate grain yield genes. We are continuously observing the genotype and phenotype of rice that possesses grain yield genes.

Health concern of dogs is the most important issue for pet owners. People who have companied the dogs long-term provide the utmost cares for their well-being and healthy life. Recently, it was revealed that the population and types of gut microbiota affect the metabolism and immunity of the host. However, there is little information on the gut microbiome of dogs. Hericium erinaceus (H. erinaceus; HE) is one of the well-known medicinal mushrooms and has multiple bioactive components including polyphenol, β-glucan, polysaccharides, ergothioneine, hericerin, erinacines, etc. Here we tested a pet food that contained H. erinaceus for improvement in the gut microbiota environment of aged dogs. A total of 18 dogs, each 11 years old, were utilized. For sixteen weeks, the dogs were fed with 0.4 g of H. erinaceus (HE-L), or 0.8 g (HE-H), or without H. erinaceus (CON) per body weight (kg) with daily diets (n = 6 per group). Taxonomic analysis was performed using metagenomics to investigate the difference in the gut microbiome. Resulting from principal coordinates analysis (PCoA) to confirm the distance difference between the groups, there was a significant difference between HE-H and CON due to weighted Unique fraction metric (Unifrac) distance (p = 0.047), but HE-L did not have a statistical difference compared to that of CON. Additionally, the result of Linear discriminate analysis of effect size (LEfSe) showed that phylum Bacteroidetes in HE-H and its order Bacteroidales increased, compared to that of CON, Additionally, phylum Firmicutes in HE-H, and its genera (Streptococcus, Tyzzerella) were reduced. Furthermore, at the family level, Campylobacteraceae and its genus Campylobacter in HE-H was decreased compared to that of CON. Summarily, our data demonstrated that the intake of H. erinaceus can regulate the gut microbial community in aged dogs, and an adequate supply of HE on pet diets would possibly improve immunity and anti-obesity on gut-microbiota in dogs.

Seed color is controlled by several genes and is a key trait in determining the metabolite content and biological activities of legume genotypes. In this study, 296 adzuki bean accessions, including 159 grey, 99 red, and 38 white adzuki beans, were grown in Korea. Variations in total phenolic content (TPC), total saponin content (TSC), DPPH^• scavenging activity, ABTS^•+ scavenging activity, and ferric reducing antioxidant power (FRAP) were assessed and were reported to be in the ranges of 1.52-8.24 mg GAE/g, 14.36-114.22 mg DE/g, 0.23-12.84 mg AAE/g, 1.05-17.66 mg TE/g, and 0.59-13.14 mg AAE/g, respectively, with a wide variation across adzuki beans. Except for DPPH^• scavenging activity, the average values declined in the order gray > red > white adzuki beans, each demonstrating a significant variation (p < 0.05). White adzuki beans, which showed low metabolite content and antioxidant activity, were clearly separated from the gray and red genotypes using principal component and hierarchical cluster analyses. Moreover, TPC, TSC, and antioxidant activities were strongly correlated, regardless of seed color. Overall, the diversity of the TPC, TSC, and antioxidant activity in a broad population of adzuki bean genotypes was determined. Furthermore, this study found that seed color variation in adzuki beans had a significant effect on the metabolite content and antioxidant activity. Superior accessions with high levels of TPC, TSC, and antioxidant activity were also discovered and could be used for functional plant breeding and human consumption. The findings of this study may be useful for understanding the relationship between seed coat color and metabolite concentration in adzuki beans, paving the way for molecular-level analyses.
