This thesis attempts to describe the basis and value system respectively selected by opinions pro and against bio engineering technology and to induce discussions on the basis of the concept called 'two culture' issue by C. P. Snow - science culture, human culture, a teleological ethical theory and a deontological ethical theory, traditional eugenics, and liberalism eugenics. In addition, it will discuss about inconvenient truth about science and bio engineering which we have wrongly understood up to now - a myth on objectivity of science, autonomy of science and a scientist, a hunger of world, science expected to be responsible for all men. Lastly, it will describe study ethics and social responsibility, openness, moral imagination, self-examination, character of a bio engineer as professionalism.

This research aims to diagnosis regional science as culture and propose plans for improvement. The study was performed based on a framework for analyses presented by existing literatures. Science culture is divided into two dimensions(individual and social), Each dimension is expected to represent citizen literacy of and regional infrastructure of science culture respectively. Gyeonggi region of Korean metropolitan area has been analyzed for the case study. As a result of the case study, the level of science culture of Gyeonggi region is weak compared with others areas. To improve, we propose some plans such as budget extension, long-term view on investments, strengthen network and organizational system for regional science culture.

This study was conducted to determine proper varieties of cucumber at four different cultural seasons. Eight varieties of cucumber from four varietal groups were grown in two types of plastic house, 1-2W type and postless type, at four different cultural seasons, retarding culture, forcing culture, semi-forcing culture and summer culture. Number of female flowers, male flowers, aborted female flowers, leaves and fruits per plant and fresh weight of fruits per plant were observed. The results were listed as follows. Varietal group of Nakhap or Hukjinjoo and ibchubakdadakioi showed better growth and higher yield at retarding culture. Kyeusalichungjangoi, ibchubdadakioi and Gaulnakhapoi could be recommended as proper varieties at forcing culture. Varietal group of Chungjang or Nakhap showed relatively higher yield at semi-forcing culture. Naboochungjangoi and Gaulnakhapoi were recommended as proper varieties at summer culture.

This study was conducted to compare various culture methods and evaluate economic feasibility of each method for mass propagation of new ever-bearing strawberry 'Goha'. Four different methods such as semi-solid culture, solid culture, liquid suspension culture and bioreactor culture were compared. The solid culture and bioreactor culture showed the shortest and longest root length, such as 3.6 cm and 8.3 cm, respectively. Fresh weights of plants cultured in bioreactor were 2,261 mg, which were heavier than those of cultures. Dry weights of plants cultured in bioreactor were the heavier compared to those in other cultures. The number of axillary bud developed in bioreactor was seven, but axillary bud was not developed in other cultures. Production cost through bioreactor culture was calculated to be 303 won per plant which was 542 won less than that of solid culture. As a result, we found that the bioreactor culture was the most cost effective culture method for in vitro mass propagation in new ever-bearing strawberry 'Goha'.

Animal cells in culture typically convert most of the glucose they consume into lactate. The accumulation of lactate, however, is commonly cited as one of the factors that inhibit cell growth and limit the maximum cell concentration that can be achieved in culture. The specific production of lactate and the amount of glucose converted to lactate can be reduced when cells are grown in a fed-batch culture in which the residual glucose concentration is maintained at low levels. Such a fed-batch culture was used to grow and adapt hybridoma cells into a low-lactate-producing state before changing into continuous culture. The cells reached and maintained a high viable cell concentration at steady state. In a similar manner, cells that were initially grown in batch culture and a glucose-rich environment reached a steady state with a cell concentration that is much lower. The feed composition and dilution rates for both cultures were similar, suggesting steady state multiplicity. From a processing perspective the desired steady state among those is the one with the least metabolite production. At such seady state nutrient concentration in the feed can be further increased to increase cell and product concentrations without causing the metabolite inhibitory effect typically seen in a cell culture. Controlling cell metabolism in a continuous culture to reduce or eliminate waste metabolite production may significantly improve the productivity of mammalian cell culture processes.

The study conducted questionnaire analysis on 607 host company employee and 404 subcontractor employee in order to examine the difference in the safety culture cognition of host company and subcontractor. As a result, host company had higher recognition in all safety culture factors compare to that of subcontractor, and there were bigger gap of cognition in the 'cognition in safety status and culture', 'accident and near-miss', 'immediate superior's concentration degree in safety and health' than that of other cognition factors. Furthermore, team leaders showed the highest cognition in both host company and subcontractor, and employees with above 20 year career had the highest cognition in both host company and subcontractor. There is high relationship between host company and subcontractor in the correlations in safety culture cognition factors. Through this study, we identified the difference in the safety culture cognition factor of host company and subcontractor.

The origines of the Western roasting culture and East Asian boiling culture were studied and the importance of primitive pottery culture (8000-5000 BCE) in the Korea Strait coastal region was discussed. The primitive pottery culture probably initiated the Jjigae (stew) culture and the production of salt. It can be also postulated that fish fermentation, kimchi fermentation, and cereal alcohol fermentation originated during this period. Soybean culture emerged ca. 2,000 BCE in South Manchuria and the Korean Peninsula. This paper focuses on the role of Korean foodways in the food science and technology development for the sustainable and resilient food systems. We are facing a global food crisis caused by population growth, climate change, and high animal food consumption. Studies on the meat analog and cultured meat are the new trend in Food Science and Technology. The importance of the wisdom learned through the Northeast Asian traditional foods, for example, soybean curd (tofu) and meaty flavor production by fermentation for the research on the novel sustainable and resilient food systems are discussed.

Korea has accomplished remarkable economic growth based on the accumulating technological capability. Science and Technology policy aiming at quantitative growth has concentrated on S&T hardware infra-structure construction but it overemphasizes technological factors. This policy has not sufficiently reflected social and cultural elements that should be incorporated in S&T development process. Therefore many experts have been emphasizing the importance of science culture as an important ingredient of S&T policy. This paper aims at investigating how science culture could be diffused. Nowadays, many countries have a strong interest in science shop as an important instrument of science culture. Science shop, however, has been activated in European area so it is not familar to Korea. However there are already a few science shops in Korea. In this paper, we will investigate the Korea science shops. In particular, we will analyze the current status, organizational structure and problems of Korea science shops. we will draw some important policy implications to activate science shops and to strengthen S&T policies in Korea.

This paper examines theoretical trends and policy issues concerning science and public. The dominant perspective about it was changed from “popularization of science” to “public understanding of science (PUS)”. PUS pays attention to active roles of public in the understanding of science based on the contextual model. And recently various concepts are attempted to complement PUS such as “heterogeneous PUS”, “quantitative PUS”, “public understanding of research”, and “public participation in science”. PUS related activities in Korea can be analyzed using the concept of “science and technology culture system”. The characteristics of science and technology culture system in Korea can be summarized as follows: Its purpose is confined to support existing national innovation system; Its constituents have been unevenly and separately developed; Its material and institutional infrastructure is not sufficiently prepared; Its organizing mechanism is strongly influenced by government's execution power.
