This study assessed the effects of treatment with sap extract from onion residues postharvest and purslane on the quality and quantity of organic onions. At the bending stage, onions treated with the sap extract showed vigorous growth, with higher plant heights, more leaves, and longer sheath lengths than untreated onions. The onion yield was significantly increased when the plant was treated with extracted sap as compared with that of untreated plants (p<0.05). The bulb weight distribution of onions in the mixed onion and purslane treatment was also significantly increased (~300 g) as compared with that of the other treatment (p<0.05). Except for CaO and S, the mineral content of the onions produced from plants treated with the onion and purslane extract mixture was higher than those of onions in the other treatment. The hardness of onions produced from plants treated with the onion and purslane extract was significantly increased (8% and 20%, respectively) as compared with that of onions produced from plants treated with the onion extract only or no treatment (p<0.05). However, there was no significant difference in the sugar contents of the onions produced from extract-treated and nonextract-treated plants. Postharvest, the content of inorganic components (phosphate, calcium, sulfuric acid, and manganese) was higher in soil treated with the onion extract than in soil treated with the onion and purslane extract and non-treated soil. It can be concluded that residues left after onion harvests and purslane extract can be used as natural and environmentally friendly materials for the cultivation of organic onions.

Following the emergence of a knowledge-based economy, the role of universities in regional development has been re-evaluated through considering localized interactive learning processes. This paper tries to identify the role of universities for regional development and the variables effecting on their localized engagement in regional development. We argues that universities cannot be viewed as a single angle, because the behaviors of a university are influenced by the degree of their independence from regional and national governments. Likewise, the contributions of universities to their regional development can be differential depending on the organizational characteristics of individual universities, the social, political, and economical contexts of a given region and nation, and complex relations between and within universities and other regional stakeholders. These variables can be both the drivers and barriers when each university responds to regional needs. Based on the literature review, we suggest that the explanatory factors of shaping the engagement of universities in regional development can be classified into four categories: the characteristics of individual universities, the national context, the local and regional context, and the policy context.

This study examines spatial characteristics of residential distribution and occupational composition of Korean emmigrants who live in China, United States, and Japan. The data used are The Conditions of Korean Emmigrants published by Ministry of Foreign Affairs in 1995. Analysis method used this data are as follows: 1) to clarify the tendency and spatial distribution of Korean emmigrants in each nation. 2) to grasp the residential distribution of Korean emmigrants in China, United States, and Japan where many Koreans have lived. 3) to analyze the occupational composition and its spatial characteristics of Korean emmigrants. The main findindgs obtained are summarized as follows: Farmer, forester, stock farmer, and fishery occupy over 50% of the employees of Korean emmigrants in China; traders and other employees occupy about three-fourths of the employees of Korean emmigrants in United States; and other employees occupy about 80% of the employees of Korean emmigrants in Japan. Therefore, the ratio of occupational composition of Korean emmigrants was influenced by emmigration motive, level of economic development of emmigration nation, restrictive condition for ethnic minority, and social status before emmigration etc. Specialized occupational composition in region where many Korean emmigrants in each nation lived was that the highest specialized occupation in region including primary city in population scale is trader; the highest specialized occupation in region including secondary city is manufacturing employee, and the highest specialized occupation in region including third city has transitional characteristics of each region including primary and secondary city. And professional occupation such as lawyer, doctor, religionist and educator appeared to the region including primary city. Finally, Korean emmigrants in United States and Japan contributed to the revitalization of inner city areas. And potential ethnic organization can be seen in church, mass media, and enterprise association in United States, but it can be seen in community shopping association in Japan, Because American society is based on Christianity but Japanese society is not.

This study analyzed the current situation of medium and small-sized hospital nursing staff and related policies, and identified the factors that affect staffing level to provide evidence for planning and adopting policy. By analyzing the statistical data published by public institutions such as the Ministry of Health and Welfare and Health Insurance Review and Assessment Service, the result was viewed based on the understanding of various internal and external health care environments. The number of active nurses was less than 50% of the number of licensed nurses and has decreased every year. This means that the cost-effectiveness of increases in nursing college enrollment should be reconsidered. Inpatient nursing fees by staffing grades has caused nurses to move from medium and small-sized hospitals, where there is a severe lack of staff, to more advanced general hospitals. As a result, the lack of nursing staff in medium and small-sized hospitals has worsened. In conclusion, reexamination is needed to improve effectiveness of inpatient nursing fees by staffing grades as a policy to secure the workforce of medium and small-sized hospitals. Furthermore, the tracking management system of licensed nurses must be able to solve the imbalance between demand and supply of nursing staff.

Through the increasing use of internet and smart device, consumers can search the information what they want to find. The information has been accumulated and become into a big data. Analyzing the big data regarding key words associated with foods and foodborne pathogens could be a method for predicting foodborne illness outbreaks, especially in school food services. Therefore, the objective of this study was to elucidate the correlations between key words associated with foods and food safety issues. Frequencies of the key words for foodborne pathogens and food safety issues were searched using an internet portal site from January 1, 2012 to December 31, 2014. In addition, foodborne outbreak data were collected from Ministry of Food and Drug Safety for the same period of time. There was correlation between the time having maximum key word frequencies of foods and foodborne pathogens, and the time for foodborne illness outbreak occurred. In addition, the search frequencies for foods and foodborne pathogens were generally increased right after foodborne outbreaks occurred. However, in some cases foodborne outbreaks occurred after the search frequencies for certain seasonal foods increased These results could be useful in food safety management for reducing foodborne illness and in food safety communication.
