In recent time, rural-studying programs have emerged as an alternative to promoting exchange between urban and rural areas. The purpose of this research will be to take a look at such exchange activities through the study of cases involving rural areas using its human and material resources. The research will also consider the implications resulting from the possibility of its application in Korea. According to a Japan's rural-studying program, there was a whole family participation and there was cooperation between the school, village and the local government. There are some domestic places that applied this program, but only a few are successfully being implemented. To increase the possibility of successful application, building network systems between rural-studying schools will be vital. So will be the building of critical infrastructure to induce the return to farming and the establishment of assistance institutions. Also, visible assistance towards farms in rural area and conversion of recognition upon exchange activities between urban and rural will be necessary. Legislation of rural-studying program, establishment of local government assistance ordinance and continual education to local inhabitants will be central to the role of central and local government.

A cross-sectional study involving 400 mothers was conducted in the Manya Krobo district of Ghana with the objective of studying household dietary practices, quality of diets and family nutritional status of rural Ghana, A combination of methods, including structured interviews using questionnaire, dietary assessments and anthropometry was used to collect data for the study. The data obtained was analyzed using Statistical Package for Social Sciences (SPSS) Version 10 in Windows. Means and standard deviations were generated for continuous variables and frequency distribution for categorical variables. Most women consumed meals three times a day but only a few (12.5%) cooked all three meals at home. Breakfast and lunch were the two main meals purchased from food vendors. The most frequently consumed food items on daily basis were the starchy staples, maize, fish, pepper, onion, tomato and palm fruits. The nutritional qualities of diets were poor in terms of calcium and the B-vitamins. A significant proportion of the women were nutritionally at risk of being either underweight (12%), overweight (17%) or obese (5%). For adequate nutrition in this population, nutrition education intervention programs aimed at improving nutrient intake through improved diet diversity and increased use of local foods rich in calcium and the B-vitamins needs to be undertaken. There is also the need to intensify education on excessive weight gain and its attendant health problems in the area.

Urban landscape represents a city's internal identity as well as external form. Therefore, urban landscape and image planning has to involve marketing strategies to deliver the economic growth and regional revitalization through recreating the environmental and cultural value of the city. This study intends to develop practical city image management programs as city marketing tools which consider opinions of local authorities, related experts, and residents. To achieve this purpose conjoint analysis was applied on three components which symbolically reflects features of assets and resources in Anseong. This study can be summarized as follows: 1. The first consideration for Lake Geumgwang is to develop farm experience Programs on waterside fields. 2. The rot consideration for Bauduki Festival is to make efforts for public relations(PR) to be able to merchandise festival-related goods and develop unique products. 3. The first consideration for Anseong Grapes is to build leisure-oriented theme parks for local farm products. This study is meaningful to develop the efficient and quantitative management method of city image for marketing. The integrated approach to the management programs to reflect opinions of local policies, experts and citizens is expected to become a useful foundation in studying city images and marketing.

Wheat is a very important crop as a food source worldwide, but gluten in wheat causes a variety of allergic reactions. Previous studies have developed ${\omega}-5$ gliadin deleted O-free, known as the central antigen of WDEIA (wheat-dependent exercise-induced anaphylaxis). In this study, we performed RNA sequencing on the grains and leaves of the allergic-reduced species O-free and their cultivars, Keumkang and Olgeuru, to analyze differentially expressed genes (DEG) based on different cultivars and tissues. Tissues of all species were biologically repeated three times. We used bowtie2 version 2.3.5.1 to get sequence data from RNAseq and used cufflinks and Tophat programs to find DEG. When comparing leaf and grain tissues, a total of 1,244 DEGs were found in the leaf tissues while only 563 DEGs were found in the grain tissues. As a result of gene ontology analysis of differentially expressed genes, the leaf tissues were mostly included in the "catalytic activity" part of molecular function, "metabolic process" part of biological process, and "membrane" part of cell component. The grain tissues were mostly included in the "metabolic process" part of biological process, "binding" and "catalytic activity" part of molecular function, and "membrane, cell, cell part" parts of cell component. Based on these results, we present information on the differentially expressed genes of the three cultivars of leaves and grains. This study could be an important basis for studying the characteriztion of O-free.

Orchidaceae species account for one-tenth of all angiosperms including more than 30,000 species having significant ecological, evolutionary, and economic importance. Despite Orchidaceae being one of the largest families among flowering plants, crucial cytogenetic information for studying species diversification, inferring phylogenetic relationships, and designing efficient breeding strategies is lacking, except for 10% or less of orchid species cases involving mostly chromosome number or karyotype analysis. Also, only approximately 1.5% of the identified orchid species from less than a hundred genera have genome size data that provide crucial information for breeders and molecular geneticists. Various molecular cytogenetic techniques, such as fluorescence in situ hybridization (FISH) and genomic in situ hybridization (GISH), have been developed for determining ploidy levels, analyzing karyotypes, and evaluating hybridity, in several ornamental crops including orchids. The estimation of genome size and the determination of nuclear DNA content using flow cytometry have also been employed in some Orchidaceae subfamilies. These different techniques have played an important role in supplementing beneficial knowledge for effective plant breeding programs and other related plant research. This review focused on orchid breeding summarizes the status of current cytogenetic tools in terms of background, advancements, different techniques, significant findings, and research challenges. Principal roles and applications of cytogenetics in orchid breeding as well as different ploidy level determination methods crucial for breeding are also discussed.

This study was designed to grasp the knowledge and practice the level about visual impairment protective care of the primary school students and also analyse the state of visual impairment. The subjects of this study ware 347 students composed of 456 boys and 391 girls in primary school students. The data were collected by questionaire developed for the purpose of this study which has been made through studying references. These were carried out from the 10th to 30th of June 1992. Analysis of the data was done utilizing SPSS for percentage, mean, S.D., T-test., ANOVA and Pearson's Correlation Coefficient. The major results obtained from this study were as follows: 1. The level of the knowledge about visual impairment protective care was in intermediate range (mean on 20 point scale of 12.34, with O=definitely no), but low in aspects of preventive care for overwork of eye (mean on 5 point scale of 2.67). 2. The level of the practice about visual impairment protective care was intermediate range (mean on 20 point scale of 12.34, with O=definitely no), but low in aspects of preventive care for overwork of eye (mean on 5 point scale of 2.58). 3. Significant variables influencing knowledge of visual impairment protective care were sex (p<0.01) and grade (p<0.001). 4. Significant variables influencing practice of visual impairment protective care was living area (p<0.01). 5. Correlation between knowledge and practice: Those who have more knowledge score have more practice score (p<0.001). 6. vision impairment state 1) Student with subnormal in 0.9 or less were 26.3% in left eye and 28.4% in right eye. 2) Student with subnormal in 0.6 or less were 11.9% in left eye and 10.9% in right eye. 7. Vision impairment programs 1) Males are slightly higher in the degree of visual impairment than females. 2) Visual impairment were increased in accordance with the increase of grade. 3) Urban students are higher in the degree of visual impairment than rural students, but these seem to have no statistical meaning.
