Background: A typical sewage treatment plant is designed for organic and nutrient removal from municipal sewage water and not targeted to eliminate micropollutants such as pesticides, pharmaceuticals, and nano-sized metals which become a big concern for sustainable human and ecological system and are mainly discharged from sewage treatment plant. Therefore, despite contaminant removal by wastewater treatment processes, there are still remaining environmental risks by untreated pollutants in STP (sewage treatment plant) effluents. This study performed aquatic toxicity tests of raw wastewater and treated effluents in two sewage treatment plants to evaluate toxicity reduction by wastewater treatment process and analyze concentration of contaminants to reveal potential toxic factors in STP effluents. Methods: Water samples were collected from each treatment steps of two STPs, and acute and chronic toxicity tests were conducted following USEPA (United States Environmental Protection Agency) and OECD (Organization for Economic Cooperation and Development) guidelines. Endpoints were immobility for mortality and reproduction effect for estrogenicity. Results: Acute $EC_{50}s$ (median effective concentration) of influents for Seungki (SK) and Jungnang (JN) STPs are $54.13{\pm}32.64%$ and $30.38{\pm}24.96%$, respectively, and reduced to $96.49{\pm}7.84%$ and 100%. Acute toxicity reduction was clearly correlated with SS (suspended solids) concentration because of filter feeding characteristics of test organisms. Chronic toxicity tests revealed that lethal effect was reduced and low concentration of influents showed higher number of neonates. However, toxicity reduction was not related to nutrient removal. Fecundity effect positively increased in treated wastewater compared to that in raw wastewater, and no significant differences were observed compared to the control group in JN final effluent implying potential effects of estrogenic compounds in the STP effluents. Conclusions: Conventional wastewater treatment process reduced some organics and nutritional compounds from wastewater, and it results in toxicity reduction in lethal effect and positive reproductive effect but not showing correlation. Unknown estrogenic compounds could be a reason causing the increase of brood size. This study suggests that pharmaceutical residues and nanoparticles in STP effluents are one of the major micropollutants and underline as one of estrogenic effect factors.

Conditions of farm crop switching are affected by several important external factors such as agricultural products import opening, policy support, and climate change. Farming environment is always changing; barriers to imports are becoming lower and lower because of FTA and others, and climate change affects a boundary line of cultivation. Those situations give farmers motivation to change crops in order to cope with them. In addition, crop switching has been done in response to the local government measures about purchase of local agricultural products according to the local food and the expansion of organic agricultural products in school meal. Even though the favorable environment toward crop switching has been created, there are not many researches or outcomes regarding crop switching. Only few studies focus on the list of decision-making in crop switching, and locally suitable crop selection is not treated. In order to utilize crop switching as a farm management strategy, the proper frame should be studied and practical researches on application possibility also need. Therefore, study on crop switching is in a timely, proactive manner because farms catch the chance of expansion of school meal by changing crops. This paper applies HERO model used for venture foundation process to crop switching process. Success factors of HERO model are comprised of Habitate, Entrepreneurship, Resource, and Opportunity, and these phased application factors are applied to crop switching process. By doing so, each phase success factor of crop switching can be uncovered. Three farm organizations supplying organic agricultural products to schools are studied in Gyeonggi province. As a result, the stabilization stage cannot be achieved because of the habitate conditions and social conditions with low risk bearing of crop switching and current school meal systems are the main problems to block the diversification of risks. In order to succeed in crop switching, constructing the habitate in local districts or in systems of school meal is more effective than supporting each farm.

Korea economy's latent growth rate has already been decreased about 4%. During 1983-1989, the latent growth rate was 8%, before the foreign exchange crisis, 1990-1997 was 6.7%, and during $2000{\sim}2004$, it had been decreased 4.4%. The latent growth rate means economy growth rate which one nation can achieve capital, labor, and factors as applying these. Our economy growth rate was 8% in 1980s, but it had been decreased about 6.7% during $1990{\sim}1997$, after 2000, it remarkably decreased 4.8% which shows weakness of our economy's strength. This study attempts to investigate about export growth factor of venture company in our nation's growth that depends on export. This thesis studied the companies continuance and growth in external environment's regular correlation and casual relationship which surround company's factors and internal. Also, the external environment, which surrounds company, can be thought that company can't control itself, so that the company's continuance and growth can be decided because of its internal primary factors. This thesis establishes and analyzes the study model that how factors can affect to company's growth.

Fundamental advances in the biotechnologies are exerting a profound influence on the health care, agricultural, industrial chemical, environmental, and other industrial fields. Korean government are now more and more realizing the importance of biotechnology as a main technology for the 21st century. But any technical progress is largely the result of a complex set of relationships among the firms, institutions and others involved in development. So understanding the complexity is very important to make promoting strategies and it is even critical in the field of biotechnology. The reason is that commercialization of research results in biotechnology is strongly related with the national science bases provided by academic and public institutes. And its applicable industrial sectors are very diverse. So it is very important to make a effective collaboration system among many R&D related agents. This article discusses and compares both USA and Japanese framework of national innovation systems in the field of biotechnology. The American Innovation system encourages basic research in the biological sciences, and fosters the creation of small venture firms that focus on the development of novel products. America's peculiar incentive structure, derived from its research and educational system, financial system, and regulatory environment has driven USA labs and firms to the forefront of many biotechnology fields. The Japanese institutional environment in contrast, supported the strategy of building production expertise. Firms were urged to use the new techniques as a way of leapfrogging into a second generation of bio-products, in that cost and production advantages count. But the strategy was not effective as expected and Japanese firms have remained competent but not prominent rivals. The differing situations in USA and Japan with regard to biotechnology have many suggestions for our bioindustry. In the conclusion of this article, we translate USA and Japan's experiences to some suggestions which guide for promoting Korea's biotechnology R&D and commercialization activities.

The mobile user interface becomes important to access information fast and conveniently, especially in the ubiquitous computing environment. Among many new services in the mobile computing environment, ubiquitous information networking service was studied using korean alphabet (consonant or vowel) domain-names including Korean single-character domain-names. Instead of handling long English/Korean URL-strings, as convenient user interface for information access, the Korean single-character/alphabet domain names are more convenient than long URL strings to retrieve information and to send information in the wired Internet as well as in the mobile Internet. We studied the convenience of Korean alphabet domain names with PCs as well as with mobile phones. We introduce the Implementation and the application of ubiquitous information portal, which has the functionality of Text to Speech (TTS) and is accessible with Korean single - character/alphabet domain - names.
