In spite of the importance of a fishing industry, neither any terminology defined in details nor academic systems to educate the workers in the fishery were established in the fisheries social education. The fisheries social education was considered to be the practical area around the actual fields. Therefore, on-site education was very important. Accordingly, this study collected and analyzed theoretical basis of a social education and data on the rural adult education and examined the actual status of the fishing industry in Korea and fisheries extension services enterprise and fisheries developmental enterprise corresponding to the actual fisheries social education conducted in Korea. On the basis of these frames, this study summarized the direction for the progress of fisheries social education that has not been studied until now for the purpose of suggesting the future directions of the fisheries social education as follows; The recognition on the importance of fisheries social education and fundamental researches in the fisheries social education should be extended. The practical development of fisheries social education should be realized. Fisheries extension services enterprise should be evolved by fishermen. The abilities of instructors in the fisheries social education should be improved. The academic factors in the fisheries social education should be emphasized. Inter-disciplinary and multi-disciplinary approaches should be adopted. Various programs should be developed for the progress of the fisheries social education. The exclusive department in charge of the fisheries social education should be established. The information system for the fisheries social education should be secured. The industry, academic organizations and the organs should make cooperation. The fisheries social education should be provided by general social education institutions for the progress. The fisheries development should be deployed on the basis of environmental preservation. It is necessary to deploy the new fishing village movement like the Saemaul movement to the fisheries. The administrative and financial supports for the fisheries social education should be expanded. It is essential to cultivate the future fishermen for the international competitiveness.

This study is based on data from the food consumption survey on 727 members of 125 farm households from 7 different provinces. The survey was conducted in May, 1975 in cooperation with the O.R.D. The results obtained in this study are summarized as follows. 1. The average consumption of the basic food groups per capita per day was 563 g for cereals and grains(398g of rice and 129g of barley), 87.6g for meats and legumes, 317.8g for fruits and vegetables, 25.7g for milks and small fishes, 9.1g for fats and oils, and 45.1g for other group. 2. The average daily consumption of calories and nutrients was 2256 cal and 11.7g for animal proteins, 70.5g for total proteins, 21.6g for fats, 537.4mg for calcium, 18.1mg for iron, 5375lU for vitamin A, 1.27mg for thiamine, 1.05mg for riboflavin, 15.5mg for niacin, 77.7mg for ascorbic acid. When these figures are compared with the recommended allowances for Korean, the calories and nutrients intakes were satisfactory, except for the intakes of animal protein which was below two third of the recommended allowance. 3. The diets of the projected villages differed from those of the non-projected villages in the following respect: (a) The amounts of animal proteins and fats were larger in the projected villages than in the non-projected villages. (b) The percentage contribution of fats to the total amount of calories from three nutrients, carbohydrates, proteins and fats was higher in the projected villages than in tile non-projected villages. (c) The percentage contribution from carbohydrates to the total amount of calories was higher in the non-projected villages than in the projected villages. 4. Certain physical and clinical symptoms were observed among the people in the rural areas, which can be related to the shortages of animal proteins and fats in their diets. It is recommended to pay special attention to the nutrition of school children in the Korean rural areas.

Poymer blends of two degradable aliphatic polyesters, relatively expensive material polylactic acid (PLA) and relatively inexpensive material poly(butylene adipate-co-terephthalate) (PBAT), were used in this study. Three different kinds of modifiers were used with various amounts. Diisocyanate type methylenediphenyl 4,4'-diisocyanate (MDI) and hexamethylene diisocyanate (HDI) were used as modifiers and epoxy type coupling agents also used. The melt flow index (MFI) and dynamic viscoelasticity of various compositions of PLA/PBAT blends were studied. The mechanical property and morphology with respect to the fracture surface of PLA/PBAT blends were also investigated using tensile test and field emission scanning electronic microscopy, respectively. These tests were also used to verify the compatibility of PLA/PBAT and the effect of mechanical properties due to the use of modifiers. Tensile properties of PLA/PBAT blends modified with HDI were improved remarkably.

Since the late 1990s dualistic spatial structure has been configurated in Icheon ceramic industrial space due to the articulation of transmitted ceramics space rooted from imitating the Goryeo and Joseon ceramics and contemporary ceramics space based on academic ceramic arts. Therefore, the main purpose of this paper is to identify the formation of dualistic space in Icheon by investigating the development paths of ceramic industry in historical perspectives and analyzing inter- and extra-firm relations in Icheon. The main results of this research are as follows. Firstly, the development path of transmitted ceramics has declined gradually, while the development path of contemporary ceramics has been embedded in Icheon region. Secondly, the research pointed out that networks of transmitted ceramics and contemporary ceramics are different in the perspectives of inter-firm and extra-firm relations. Thirdly, the government has played a critical role as a financial and administrative supporter and as a network broker between university and Icheon ceramic firms(mainly with transmitted ceramics) for technological cooperation and collaborative R&D.

In this paper, We propose real-time sound editing and playback systems which is based on Augmented Reality. The proposed system are composed with music maker which is based on AR maker and music board. By using music marker's contents, the proposed system selects the kinds of musical instruments and pre-defined midi track and by calculating the relative location of music marker on 2-dimensional plane, we set the spatial relative parameter in midi track. For performance evaluation, we check the jitter value of in various resolutions by using CAM which supports $1600{\pm}1200$ as the maximum resolution. As a result, when we set the configuration value of CAM as $860{\pm}600$ pixels and process two frames per minute, the success ratio of recognizing music markers and jitter values are accegnable. It can be utilized in the fields of alternative cmacine which is based on music and also be utilized in the educational aspects because child or elderly who don't know enough musical theory can easily handle it.

As the scarcity of natural resources has become apparent, the recycling industry has emerged as a promising one for its growth potential. Yet, the recycling industry still remains undeveloped and inefficient for various reasons. In this study, we focus on firms' recycling processes to understand the current status of recycling firms' value creation activities. With respect to the adopted recycling processes, we empirically investigate the differences in firm characteristics and firm performance. We use the data from Keco (Korea Environment Cooperation) which annually conducts a survey of recycling firms in Korea. We exclusively consider the whole group of plastic recycling industry in order to control for a possible bias in firm performance, stemming from the heterogeneity in processing and recycling of materials other than plastics. We review the descriptive statistics from the sample firms and conduct a series of hierarchical regression analyses. The results show that most of the firms in this industry adopt physical transformation processes with a low-level technology. These firms with physical transformation processes are smaller in size and produce entry level items which do not secure higher margins. The results indicate that the recycling industry largely comprises low value added firms which lack economies of scale and resources for R&D. For the stable growth of the industry, recycling firms must create sustainable values through implementation of technology-driven processes and improvement in product quality. In addition, the government should help build a reliable reverse logistic network, lower the entry barriers, and provide necessary funding for the SMEs in the recycling industry.

This paper aims to suggest a policy for biological resource based on a comprehensive understanding on biological resources. Biological resources are different from traditionally recognized viable organisms (Biodiversity) in ecosystems. Biological resources are culturable and replicable resources of living organisms such as tissues, cells and genes. Moreover, biological resources include human-derived biological materials. Biological resources is not simply a matter of science and technology. Biological resources should be dealt with as national resources. There are many international issues regarding biological resources, such as intellectual property rights (IPRs), safety on handling and distribution, material transfer agreements (MTAs) for mutual benefits and biological standards. Ethical debates are also being raised because biological resources are related with human-derived biological materials. Every nation has tendency to adopt its government policies to strengthen its sovereignty on biological resources and international cooperation. In addition, international linkages are essential for providing enhanced worldwide accessibility to biological resources. Japan has shown several international initiatives in the field of biological resources. Korea has just begun to design appropriate policies for the use and R&D of biological resources. Therefore, this paper suggests the following needs: 1) policy at the national level beyond the interests of researchers, 2) inter-ministerial coordination across government ministries, 3) expansion of scope and size of each BRC (Biological Resource Centers), and 4) building networks and systems such as national information center, representative centers by field, and each BRC.

Background: Ginseng has a wide range of beneficial effects on health, such as the mitigation of minor and major inflammatory diseases, cancer, and cardiovascular diseases. There are abundant data regarding the health-enhancing properties of whole ginseng extracts and single ginsenosides; however, no study to date has determined the receptors that mediate the effects of ginseng extracts. In this study, for the first time, we explored whether the antiinflammatory effects of Rg3-enriched red ginseng extract (Rg3-RGE) are mediated by retinoid X receptor ${\alpha}$-peroxisome-proliferating receptor ${\gamma}$ ($RXR{\alpha}-PPAR{\gamma}$) heterodimer nuclear receptors. Methods: Nitric oxide assay, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide assay, quantitative reverse transcription polymerase chain reaction, nuclear hormone receptor-binding assay, and molecular docking analyses were used for this study. Results: Rg3-RGE exerted antiinflammatory effects via nuclear receptor heterodimers between $RXR{\alpha}$ and $PPAR{\gamma}$ agonists and antagonists. Conclusion: These findings indicate that Rg3-RGE can be considered a potent antiinflammatory agent, and these effects are likely mediated by the nuclear receptor $RXR{\alpha}-PPAR{\gamma}$ heterodimer.
