BACKGROUND: Spoilage fungi can reduce the shelf life of fresh fruits and cause economic losses by lowering quality. Especially, mulberry fruits have high sensitivity to fungal attack due to their high water content (> 70%) and soft texture. In addition, the surface of these fruits is prone to damage during harvesting and postharvest handling. However, any study on postharvest spoilage fungi in mulberry fruit has not been reported in Korea. This study aimed to examine the spoilage fungi occurring in mulberry fruits during storage after harvest. METHODS AND RESULTS: In this study, we isolated postharvest spoilage fungi from mulberry fruits stored in refrigerator (fresh fruits) and deep-freezer (frozen fruits) and identified them. In the phylogenetic analysis based on comparisons of the ITS rDNA sequences, the 18 spoilage fungi isolated from mulberry fruits and the 25 reference sequences were largely divided into seven groups that were subsequently verified by high bootstrap analysis of 73 to 100. Alternaria spp. including A. alternate and A. tenuissima, were the most frequently isolated fungi among the spoilage isolates: its occurrence was the highest among the 18 isolates (38.9%). CONCLUSION: The findings of this study will be helpful for increasing the shelf life of mulberry fruits through the application of appropriate control measures against infection by spoilage fungi during storage.

Recently agricultural situations are being placed in unfavourable socio-economic environment as followed by rapid decrease of rural population, poor labor quality and high wages of rural society due to high speedy industrialization of social structure in Korea. In addition to those circumstances, under the UR system to be expected in the early future, free trade of agricultural products will be faced inevitably in Korea. Practically prices of rice as a principle food in this country are expensive about three times compared to those of foreign rice markets, and so how to increase the international competitiveness and food supplies are important problems to be solved rapidly. Accordingly an urgent goal is reduction of agricultural production cost by the improvement of labour productivity as a labour saving and cost down cultivation methods as the direct seeding cultivation in rice. But there are many problems in the direct seeded rice cultivation. The important things to be improved in that cultivation are development of rice varieties with lodging tolerance, effective seedling stand, weed control, irrigation management and fertilizing and so on. Moreover agricultural basis as irrigation facilities, land consolidation and farm machineries must be improved for the stability of rice cultivation in the future.

Because of the radical changes in the domestic and foreign economic circumstances Koreaa fisheries is confronted with difficulties. Along the end of the UR marine products of other nations are rushing into Korea. Also migration of labor to other industries and rise of wage level in Korean fisheries deteriorate managerial conditions. But in Korea which has little natural resourses fisheries is still more important. That is \circled1 creating job opportunites \circled2 increase of income \circled3 supply of foodstuffs and animal protein \circled4 acquisition of foreign currency \circled5 enlargement of domestic market for industrial products \circled6 development of other interrelated industries \circled7 rational use of domestic resourses \circled8 diversification of population and production activites \circled9 contribution to balanced growth of national economy by the developing regional economy. These roles of fisheries in national economy mentioned above are to be excuted forward. In spite of the radical change in the economic circumstances at the end of the UR fisheries if crucial in Korea as a industry. For this our fisheries is to be made to compete with foreign fisheries. Through the cheap price and high quality our fisheries must be came to compete with foreign fisheries and meet the people's needs for marine products. For this it is necessary to maintain high productivity and competitive power. Now with the exception of a portion of the deep - sea fishing, our fisheries is generally paltry, Especially inshore fishery which is the main stock in our fisheries is very paltry and so productivity and competetive power are very low. So to develop our fisheries which has s comparative disadvantage active polices that follows below are to be promoted on a large scale. \circled1 improvement of structure \circled2 augmentation of productivity in fishing ground by making fisheries resourses \circled3 enlargement of finantial and monetary assistance \circled4 effective administration of fisheries cooperative union \circled5 activation of R&D etc These polices which need to be scientific and comprehensive are very valuable. Especially without making fishieries resources we cannot expect economy of scale, promotion of productivity and development of fisheries. And we do also endeavour to gather the results of the study and investigation about fisheries domestic and foreign and do ceaselessly put these to practical use systimatically.

This study was aimed at developing and providing textbook writers with information and materials required to introduce forest education ideas and paradigm into primary, middle, and high school students, responding to establishment of the new national curriculum. Research methods included interview with school teachers, literature review on forest education and policy, analysis of writings and drawings of elementary school students. As a primary result, the study produced a framework that can be applied to analyze and understand how people think of and put a value on forest, consisting of 1) Resource-Economic Perspective, 2) Environmental-Ecological Perspective, 3) Cultural-Educational Perspective, and 4) Existential-Ethical Perspective. To test its validity, the developed framework was applied to the processes of reorganizing and interpreting the outcomes of teacher interview and writings and drawings of elementary school students. The results of applications showed that current school education mostly focused on ecological-environmental (about 50%) and cultural-educational (about 30%) perspectives on forest. To improve the quality of current forest education in schools, five main directions including integration, balance, interrelatedness, identity, and systematic approaches were suggested.

The scale of global FDI has been decreasing since 2016 due to the ongoing US-China trade dispute, the strengthening of FDI inflow screening regulations with concern over strategic technology leaks, and the spread of reshoring trends due to the reinforcement of national preferences. Eventually, the competition to attract FDI between countries is expected to become more intense. Therefore, in order to attract high-quality FDI for Korea that will contribute to the development of the national economy, it is pressing to evaluate and improve the domestic FDI attraction environment. This study aims to analyze which areas of Korea's economic and non-economic environments need improvement for gaining advantage amid the fierce competition to attract FDI between countries, by the relative comparison between Korea and the U.S., and based on the ranking indicated in key FDI attractiveness indices. As a result, improvement is needed in the following areas. First, according to IMD's "World Competitiveness Ranking 2020," Korea was inferior to the US in terms of business efficiency, productivity, finance and business legislation in terms of government efficiency. Second, according to INSEAD's "Global Talent Competitiveness Index 2020," Korea was inferior to the US in terms of internal openness, external openness, employability, lifelong learning, access to growth opportunity, and business and labor landscapes. Third, according to WEF's "Global Competitiveness Index 2019", Korea was inferior to the US in terms of product market, labor market, business dynamism and workforce skills.

The purpose of this study was to identify the present use of caregiver services, to evaluate the degree of satisfaction with the services according to type of caregiver service, private or public, and to provide data for the development of a plan which will provide good quality service with less economic and psychological burden to the patients and their families. Survey data were collected from 130 patients in 4 general hospitals in Seoul, and their families. Data were collected during April, 2004, using a questionnaire which included the patient satisfaction scale developed by Jun (2001). Data were analyzed using frequencies, percentages, means and standard deviations, $X^2$ analysis, t-test. The SPSS computer program was used to facilitate analysis. The results of this study are summarized as follows; The total score for satisfaction was high for both groups. For the private caregiver group it was $52.38{\pm}11.08$, and for the public caregiver group, $58.14{\pm}9.64$. This difference was significant(t=-3.391, p=.001). In all of areas, the scores for satisfaction of the public caregiver service group were higher than private caregiver service group, ie. caregivers' attitude, role, confidence, performance, and service charge, and all the differences were significant. In conclusion, it was found that long-term hospitalization of older patients with high dependence resulted in more caregiver service. There were more severe patients in the public caregiver group, but the service charges, additional costs and paid holidays were less. Based on these results, patients and their families were significantly more satisfied with public caregiver service because it was not only less expensive but also had a high quality of service. Thus, caregiver services should be systemized so that patients and their families will get the best quality caregiver service
