According to shift of the political focus from agricultural productivity to social development, it has been increased importance of local leader in rural society. Especially rural women leader's role has been increased not only in agricultural business but also in social activity of locality. Although a lot of leadership study related to rural community development, it has been very scarcely study about leader's action in pattern or doing in style based on psychological scale. Therefore this a kind of pilot study on that. For this data, it was gathered from 24 female farmer leaders of a federation group in 2005. In this study, to define the action in pattern or doing in style of leader, it was adopted to Ozasz Yoshihisa's scale which is consisted of 40 items into 8 types. From analysis of female farmer leader's action in pattern or doing in style, most of them were belong to volunteer type, generalist type, farmer type. This menas most of them were head toward maintenance of the present status, keeping one's balance, adaptation oneself to new environment, or acceptance the logic of events, not trying to innovate. But it was not clear that any variable has a relation in the action in pattern or the doing in style, for definition of variables, it should be more detailed study.

As the number of aid projects for farming village has been increased, rural amenity is being emphasized. On the contrary, we have a shortfall in excavation and utilization of great resources due to the utilization limit for resources in each village and similarity with the resources from other areas. Thus, we're trying to investigate the ways to make effective use of excellent amenities for farming village development project. In this study, through the principal component analysis, we tried to extract the key factors from the selected areas and examine actual application case of resources. This study categorized the key resource into the big class such as development, farming, nature and experiencing and target areas were categorized into two main classes accordingly. The finding shows 5 example places selected as great areas are taking advantage of extracted excellent resources and 2 target areas are also utilizing enough of excellent resources of each area. Not only limit of used items, subjective view of researcher and resources of each area but also participatory intention of residents and management ways should be additionally considered for another study from now on.

This study was conducted to determine the occurrence of leaf rot and leaf ring spot, caused by Rhizoctonia solani in Chinese cabbage under seedling nursery and cultivation greenhouses. Symptoms of leaf rot and leaf ring spot were found in three Chinese cabbage cultivars, Brassica campestris subsp. pekinensis, 'Ryeokgwang', 'Daetong', and 'CR mat'. In Hwacheon, the disease incidence was 73.8% in the seedling stage of the Chinese cabbage. In Icheon, the symptoms were observed on the upper leaves of the Chinese cabbage cultivar, 'Norangmini' with 20.5% of disease incidence. The symptoms appeared as primary lesions consisting of small, circular necrotic ring spots with gray color, 1.4-3.0 mm in diameter, accompanied by secondary rot lesions with large irregular borders of leaves. The color of mycelial mat of 20 isolates was dark brown and light brown. The average hyphal diameter of all the isolates was within 5.01-11.12 ${\mu}m$. Among the 20 strains isolated from Chinese cabbage, 16 isolates and four isolates anastomosed with the AG-1 (IB) and AG-1 (IC), respectively. Twenty isolates tested were only virulent on foliage parts of Chinese cabbage leaves but were avirulent on stem parts of the plants. Based on the mycological characteristics and pathogenicity test on host plants, the fungus was identified as Rhizoctonia solani.

The insecticidal toxin gene of Bacillus thuringiensis (Bt) is one of the most commonly used in the development of genetically modified (GM) crops. In this research, we analyzed Bt rice showing lepidopteran pest-resistance. The Bt gene is a synthetic Cry1Ac composed of optimal codons for plants, and the Bt protein is targeted to the chloroplast by a transit peptide. Three Cry1Ac rice events (C103-3, C127-1, and C7-1) were analyzed for molecular characterization. C103-3 contains two copies of T-DNA where the left border (LB) region is truncated. Both C7-1 and C127-1 have a single copy of T-DNA, but a part of the vector backbone DNA is inserted into the genome of C127-1; thus, only C7-1 had intact T-DNA. Progenies of C7-1 crossed with the original cultivar, Nakdong, and double-haploid lines from anther culture of lines crossed with the elite cultivar, Dongjin, were analyzed for T-DNA flanking genomic DNA and genotyping. Results showed that an intact T-DNA region without the vector backbone was inserted into the genome and was stably inherited through generations. The C7-1 homozygous event could be used as breeding material to develop GM rice with pest resistance.

If a quantitative trait loci (QTL) marker identified in a population is applicable to different populations (marker universality), this will not only reduce the labor and cost in marker assisted selection (MAS), but accelerate the application of molecular markers to real breeding programs. Present study aims to evaluate the defined QTL related markers from a population to a different breeding population for the MAS. Four rice breeding populations were subjected to seventy-five simple sequence repeat (SSR) markers which were already identified for their polymorphism information content (PIC) in the parents of the crossings. Among them, eight markers were evaluated for their correlation between presence of marker alleles and phenotypic expression in breeding populations. A reasonable level of polymorphism for the mapped markers originated from any sources of rice accessions was observed between crosses of any sources (marker repeatability). However, correlation between presence of markers and expression of the traits in rice breeding populations was not significant except for minor portion of traits and markers examined (failure of marker universality). In the present study, various strategies were discussed to develop new markers with universality of breeding application.

This study was carried out to investigate the nutritional and physical status of children, aged 11 and 12 years, living in Haenam Koon (living at home) and in Mokpo City (living in an orphan asylum) located in Chonnam during the period of August 2 nd to 9 th in 1984. The mean values of height, chestgirth, arm circumference and head circumference between both groups of living in the rural area and in the city orphan asylum were not statistically different and similar to Korean Growth Standard. Exceptionally, the values of height and weight of male living at home in the rural area were lower than Korean Growth Standard (p<0.01). The weight of male living in the city orphan asylum was higher han that of male living at home in the rural area (p<0.01), and the skin fold thickness of female living at home was higher than that of male living at home (p <0.01). The physical indices of children living in the city orphan asylum were more or less higher than those of living at home in the rural area, but the relative weight of male was only significant (p<0.05). The animal protein intake was $8.4{\sim}8.6%$ of total food intake of living at home in the rural area and 6.2% in living in the city orphan asylum. The intake of legumes of children living in the city orphan asylum was more two times than that of living at home in the rural area, but overall fruit intake of living at home was more about two times than that of living in the city orphan asylum. The average intake of all nutrients except thiamine and niacin was lower than RDA. Especially the calcium intake of children in both groups was the lowest of all nutrients ($28.9{\sim}40.6%$ of RDA). Children living at home in the rural area had significantly higher intake of fat and ascorbic acid than children living in the city orphan asylum (p<0.01).

The aim of this study is to build an architectural landscaping design ways of vulnerable community in rural area. I surveyed scenery structures, public buildings and single home forms, and fence types of house in twelve villages which have undertaken improving environment of rural community in four provinces. They all have an inferior surroundings to live in rural village, because they were isolated from the city, located on the mountain or island, and made a living under the slate materials of roof. The central government has been driving to reform the conditions with local office, so that they may increase their living qualities and village environment to get to the general level of rural area. There are three results of this study as follows: First, the scenery of the village surveyed has a remarkable views of locality and hierarchy of layers between field and mountain, which is very identified as a typical image of Korean rural topology. Second, the public buildings and single homes and outside wall of houses were personally designed or reformed as a various types like a flat slab style and different architectural structure, because they followed only to keep the architectural code rather than to make a harmony with other traditional style buildings. When they have to remodel it again through SaethulMaul project, they are needed to consider of both architectural code and design guideline for the local landscape design image. Third, to make a different landscape view of each village and improve housing conditions, it should be taken a people participation design way.

Due to the rapid economic development of Korea, the bridge have been built by government over the several years. Additionally, there are too many mountain and river and the bridge have been built in rural area. But bridge designers weren't considering the bridge landscape. And bridge was a negative factor in regional landscape. Because of this, this study surveyed the landscape preferences of rural bridge landscapes according to different bridge types. The results were summarized as follows: And this research include conducting a study on visual preference according to the bridge's type and background. And, the landscape of arch bridge in the river 1 is landscape of the highest preference. The the landscape of girder bridge in the river 2 is landscape of the lowest preference. In the river 1 and 2 landscape, high preference is observed in the arch bridge and low preference is noted in the girder bridge. In the mountain 1 and 2 landscape, high preference is observed in the cable-stayed bridge and low preference is noted in the girder bridge. In conclusion, the visual preference of bridge landscape depend on the background and bridge shape, the study said. Therefore, when bridge designer design the bridge, designer have to choose proper bridge shape according to the background. This research was conducted only in bridge landscape of rural area but the visual preference of bridge landscape can be changed according to the various background. And further research is needed to analyze visual preference of bridge landscape according to the various background.

Canine vector-borne diseases (CVBDs) are transmitted by different groups of hematophagous arthropod vectors that are distributed worldwide and can cause significant health problems for dogs. The aim of this study was to investigate and compare the prevalence of selected CVBD pathogens in rural outdoor dogs based on prevention status. Between June 2017 and February 2019, blood samples were collected from 343 clinically healthy rural dogs composing two different groups: systematically managed dogs (SMD; n=92) and personally managed dogs (PMD; n=251). Vaccination and preventive medications were applied strictly following the programmed schedule for the SMD group; in contrast, in the PMD group, they were applied only when requested by the dog owners. Serological and molecular assessments showed that significantly more dogs in the PMD group were infected with B. gibsoni (P<0.001) and D. immitis (P=0.001) than those in the SMD group. These findings suggest that the regular use of preventive medications and environmental controlling efforts contribute to reducing the prevalence of CVBD pathogen infections. In addition, dogs infected with certain kinds of CVBD pathogens could remain asymptomatic, suggesting that continuous monitoring and periodic preventive treatment should be conducted even for clinically healthy dogs.
