By analyzing a nationwide survey on Korean publics, this study examines the social determinants of public support for three types of scientific research-basic research aimed at pure knowledge, applied research toward industrial application, and research for social problem-solving which aims to enhance ordinary citizens' quality of life. The present study finds the differential effects of social- and political value orientations on the level of public support for respective types of research. As ones have more progressive in their subjective political orientations, they are more likely to support research for social problem-solving than other types of research, while conservatives tend to support basic research and those with neo-liberal ideology tend to support applied research. The Korean public also tends to perceive research for social problem-solving as a counter to basic research while it has been developed against the conventional emphasis on applied research in Korea. Also, the level of support for research for social problem-solving increases with the higher level of trust in scientific authority and expertise, while it has been developed against expertism and included public engagement in science as an important element. Finally, those who have lower income tend to support for research for social problem-solving than other types of research. The implications of these findings are discussed.

Currently, many nations in the world make a strong effort to exploit the new and renewable energy. Tidal energy is the constant and regular power sources with higher and more stable quality compared to other renewable sources. The present paper reports the status of tidal energy analyzing its latest technology and development. In addition, a feasibility study on two types of tidal power plant(TPP) systems is conducted based on many assumptions, conditions and data involved in the Korea environment. The Sihwa and Uldolmok TPP are considered as the reference of tidal barrage(TB) and tidal in stream energy conversion(TISEC) type, respectively. While TB technology is currently mature and reliable, there still remain many environmental issues. Whereas, TISEC is recently received more attention due to its environmental friendly aspect. Therefore, the TISEC is believed to be very promising technology as the TPP. The unit electricity generation cost of Sihwa TPP is approximately 67.3 KRW/kWh. However, considering additional cost of Sihwa lake construction, it increases to 254 KRW/kWh. In Uldolmok, the unit electricity generation cost is calculated to be about 400 KRW/kWh, which is even higher than that of Sihwa TPP. This is ascribed to high cost of TISEC device and construction cost due to its technological infancy as well as relatively small power capacity. Nevertheless, the TISEC technology would be substantially developed in the future due to its many advantageous features.

High-protein rice flour (HPRF) was prepared by an enzymatic process using ${\alpha}-amylase$ and g1ucoamylase without cooking Process and the feasibility of HPRF as infants foods was tested. Rice flour slurry was treated with 0.25% ${\alpha}-amylase$ and 0.5% glucoamylase at $55^{\circ}C$ for 24hrs. After saccharification, the digested rice slurry was centrifuged and the precipitated paste, was then heat-dried to obtain HPRF. The protein content of the HPRF was 20.8%. On the other hand, the supernatant of glucose enriched solution was decolourized, deionized and then isomerised to furctose at $60^{\circ}C$ for 100min by using immobilized glucose isomerase column. The high-fructose solution (HFS) contained 56% glucose, 42% fructose and 2% oligosaccharide. The nutritional quality of the HPRF was compared with milk protein and soybean protein in weight gain, feed efficiency ratio (FER), protein efficiency ratio (PER) and liver weight.

Ginseng in Korea has not only the big production value but also till a good reputation from overseas in the name of 'Korea Ginseng'. Having spread rapidly nationwide from 2000 year, its production keeps on increasing but its consumption becomes lazy and its price is also falling down because of comsumer's concern about mainly overusing pesticide for ginseng. In order to cope with this problem, the government introduced the GAP certification system to ginseng in 2006 to reflect consumer's needs for food safety. This system will be a good opportunity to promote ginseng consumption dramatically. In this aspect it is very important to know how well this system is established and how ginseng farmers build marketing strategies to draw new wind in the market. This study was carried out to look over the GAP certified ginseng system and show its marketing strategies using 4P's(product, place, promotion and price). The main results are as follows. GAP ginseng system currently has some weaknesses such as lack of systematic certification management and after-service, nonrealistic certification fee and poor linkage from production to consumption. In the marketing mix strategies, product strategy suggests that the most desirable appearance be transplanted ginseng filled with branch roots and 4 to 5 year-ginseng, and it is necessary to choose multi-brand strategy divided for present into for self-sufficiency and family brand strategy by use if its brand enlarges to processed products in the future. In the place strategy, 3 stages like 'producer group' - 'GAP certified facility' - 'sales shop' are based as the physical marketing channel according to traceability, and connected with giant retail market and environment friendly stand, and if its sales volume enlarges, it should be considered the GAP ginseng specialized marketplace which is a type of chain store. In the promotion strategy, the promotion of government level is necessary at first and producer alliances require the promotion targeting at the group of women under 40 with differentiation from price, quality, and safety. In the price strategy, the early stage-high price strategy which sets 20~25% higher for self-sufficiency and 30~35% for present is desirable.

Bioprocessing technologies utilizing 'biorecognition' between a solid matrix and a protein is being widely experimented as a means to replacing the conventional, solution-based technology. Frequently the matrices are chromatographic resins with specific functional groups exposed outside. Since the reactions of and interactions with the proteins occur as they are attached to the solid matrix, this 'solid-phase' processing has distinct advantages over the solution-phase technology. Solid-phase refolding of inclusion body proteins uses ion exchange resins to adsorb denaturant-dissolved inclusion body. As the denaturant is slowly removed from the micromoiety around the protein, it is refolded into a native, three-dimensional structure. Once the refolding is complete, the folded protein can be eluted by a conventional elution technique such as the salt-gradient. This concept was successfully extended to 'EBA (expanded bed adsorption)-mediated refolding,' in which the denaturant-dissolved inclusion body in whole cell homogenate is adsorbed to a Streamline resin while cell debris and other impurity proteins are removed by the EBA action. The adsorbed protein follows the same refolding steps. This solid-phase refolding process shows the potential to improve the refolding yield, reduce the number of processing steps and the processing volume and time, and thus improve the overall process economics significantly. In this paper, the experimental results of the solid-phase refolding technology applied to several biopharmaceutical proteins of various types are presented.

This study first reviews the evolving literature on industrial innovation policy and thereby identifies three main goals of such policy. The first goal is traditional industrial policy aiming growth of existing and future industries, the second goal is sustainable development and quality of life, and third goal encompasses the issues related to supply chain and economic security. Then, the paper evaluates industrial innovation policy goals of the five economies (United States, China, Germany, Japan, and Taiwan) in terms of the relative weights given to each goal by each economy, and derives implications for Korea. The United States emphasizes economic security and supply chain stability amid its rivalry with China. In contrast, China focuses more on traditional industrial policies but has recently begun to consider supply chain and economic security. Germany and Japan tend to give similar weights to each of the three goals. Taiwan follows this trend with a new and additional emphasis on economic security given the rising threats from China. For Korea, economic security may not be the top priority, unlike the two super-powers. Instead, it seems more appropriate for Korea to follow Germany or Japan to prioritize supply chain stability and technology sovereignty, and, at the same time, fostering future growth industries must be still an important goal. Further, the concept of economic security for Korea should include promotion of defense industry and food security.

This study examined the purchasing behavior and satisfaction of people with convenience store PB foods. The factors affecting the purchasing behavior and the overall satisfaction with the convenience store PB foods were examined. This study first found that the purchasing motivation of PB foods is the cheaper price than NB foods. Second, age is a statistically effective variable for the visit frequency at the convenience store and gender and age are effective variables for the purchase frequency of PB foods. Third, there is a statistically positive correlation of convenience store brand preference with the PB food brand preference for 6 food categories. Next, in terms of the attribute-level satisfaction, the most satisfied areas are diverse food groups and diverse food taste and the least satisfied areas is price. This is followed by taste and design/packaging influence overall satisfaction. From this analysis, the following suggestions were drawn. First, because consumers are likely to be matched convenience store brand preference and PB food brand preference, advertising is necessary to ensure that the consumers continue to visit the convenience store. Second, product improvement by increasing the quality should be designed to motivate the major consumer group of people in their 20s and 30s. Finally, to boost PB food satisfaction, the industry should improve the taste and design/packaging.

Various concepts and practices of public deliberation have been exercised over the last three decades in western countries for science and technology (ST) governance. There has been a general social consensus for the need of such new governance notwithstanding, ends and means to achieve it varied. Among various rationales, while normative and substantive perspectives are explicitly claimed in public as reasons for public engagement in ST policy making, instrumental perspectives tend to be implicitly arranged by interested parties and still affecting policy significantly. This paper therefore, examines the implications of such instrumental perspectives in public engaged ST governance. To do so, this paper analyses the discourses and practices of public deliberation for ST governance in the UK from the late 1990's until the mid 2000's. It examines the proposals made by various policy institutions and two real public deliberations- the GM Dialogue for commercialization of genetically modified crops and the Committee on Radioactive Waste Management(CoRWM)'s programme. This study finds that policy institutions tried to employ public deliberation as strategic instrument for their policy interest, which contrasted with their outwardly claimed rationales of democratic policy making and better quality in decision for ST governance.
