This study defines the biotechnology industry, examines its position in the domestic economy, and analyses its structure with I-O tables of year 1985, 1990 and 1995. Structural decomposition analysis is used in order to estimate the impact of different sources of growth. We classifies Korean biotechnology industry into 6 sectors, based on the survey of domestic biotechnology industry by Bioindustry Association of Korea. Empirical results indicate that each sector of bioindustry has various sources of growth and industrial demand has led the growth in all sectors except for food-bio and agriculture-bio. For the growth of the industry, each sector needs to cope with the change of the private demand and to improve the import and export structure.

The biotechnology is the study of biochemical and biological processes in living things. Since 1990's biotechnology has developed more repidly than all of the life technical industries, through the use of extremly sensitive analytical instruments, computers, and radioactive tracers. The biotechnician has been able to gain an understanding of the mechanisms and information on biotechnology, enables the biologist and biochemist to fine farther information about DNA techniques and human beings.

Korea is the urgent need to diversify the bio-energy raw materials because we have narrow area of land cultivated plants and lack the bio-mass resources. Using a resource-rich the marine environment enclosed on three sides by the sea. Through bio-energy production-technical and carbon dioxide reduction measures which will be a very effective alternative. Sustainable development about algae bio-energize industry through SSaM-GG(Smart, Shared and Mutual-Green, Growth) is expected. Algae has high carbon dioxide absorption factor, extracting oil from algae is thirty times much more than sunflower.

In Korea, currently, only the growth possibility of bioinformation industry has received the public attention, and social discussion on bioinformation management is meager. Based on this critical perspective, this study investigates the current status of public awareness of the bioinformation which can be a basis for the social discussion for bioinformation management. The most significant characteristics identified in the survey is that many citizens, while expressing their agreement on the use of biometric technology by purpose and taking an open stance on national fingerprint information collection, have considerable concern for the identity authentication system using the current biometric technology. In particular, the survey pointed out that it is hard to trust the institutions that collect the bioinformation. Also, the public expressed the particular concern for the health data including the body information and showed overwhelming consent for the necessity of more stringent regulation compared with other personal information. In regards to the medical information gathered from medical institutions, nearly 80% of the survey respondents did not agree on providing the information to commercial enterprises, and even 60% of them disagreed on using it for academic and statistical research. This result well demonstrates that thorough management of the bioinformation is required for its utilization.

This study aimed to identify the hepatoprotective effects of a fermented Chrysanthemum indicum L. water extract. The extraction yield, antioxidant activities (ABTS and DPPH), and content of luteolin and luteolin-7-glucoside were significantly higher in the fermented C. indicum L. water extract (FCI) than in the C. indicum L. water extract. Treatment with FCI (200 ㎍/mL) significantly reduced the activities of gamma(γ)-glutamyl transferase, aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase in HepG2 cells treated with 3% ethanol. Furthermore, FCI did not affect the viability of the HepG2 cells. These results suggest that FCI can be useful for the development of an effective hepatoprotective agent.

Particulate matter (PM) is an air pollutant that causes serious environmental problems in Korea and other countries. The annual average PM10 concentration in Korea is around 40 ㎛/㎥, which is more than twice as high as the WHO recommended standard. When consumed with food, fine PM can pose a risk to humans. However, the risk of fine PM has been focused on the risk of fine PM introduced through the respiratory system. We investigated the quantitative measuring methods of PM10 on food surface to identify possible risk analysis of fine PM. The surfaces of food with artificially contaminated PM10 were observed with a scanning electron microscope(SEM). An automatic object-based image analysis was used to analyze the amount and size distribution of particulate matter contained in SEM micrographs.

Green houses provide a more conditioned and warmer environment than the outside environment due to insulation. Currently used insulation materials include soft film (PVC, PE, EVA), foamed PE sheet, non-woven fabric, reflective film, and multi-layer insulation curtain, but there are many disadvantages and to compensate for this, silica aerogel insulation material with excellent warmth, light weight, and small volume Research using is in progress. In this study, the temperature change of the quadruple-structure green house and the temperature change in the dual-structure green house of soft film and silica airgel were investigated. The daytime temperature change was highest in A and A2 (soft film) at 10 to 16:00 after sunrise, but showed the lowest temperature at 17 to 18:00, which is the sunset time, showing the greatest change. The airgels of D and D2 showed the smallest change in temperature after sunrise and right after sunset. That is, it can be said that the airgel is hardly affected by external temperature. The temperature change at night was highest in D and D2 (aerogel) for both quadruple and dual structures. The temperature at night was measured higher in the quadruple structure than in the double structure. As for the ratio of the internal temperature to the external temperature for the quadruple structure and the double structure, D (aerogel) was not affected by the external temperature during the day in the quadruple structure and the double structure. D (Aerogel) seems to be able to reduce the damage caused by high temperatures in summer due to the high thermal insulation effect of the airgel, as the temperature rises above 4℃ at night. And in winter, it helps to save heating costs due to less heat emitted to the outside.

Functional cosmetics are products that help emphasize certain functions such as skin whitening, wrinkle reduction and UV protection. Functional cosmetic items have expanded since 2017. Korea's functional cosmetics industry has focused on skin whitening, wrinkle reduction, UV protection, and high-performance items including medical cosmetics that are in the research and development stage. France leads the international export performance rankings followed by the United states and Germany. France's cosmetic industry is renowned for emphasizing mechanism driven functional cosmetics in bio-industrial and functional materials, while the United states cosmetic industry is in high demand for luxury premium products. The German cosmetic industry is showing growing strength in bio high tech functional cosmetics. For the Korean cosmetic industry to challenge the top 3, it will also have to develop new material of various functional cosmetics that can be applied to emerging industries, and develop a variety of industry equipment in an environment where politics and economy are backed by more focus on research.

This paper analyzed the impact of alliances on the market value of the 106 bio-pharmaceutical companies listed on the KOSPI or KOSDAQ in Korea by using the 'Event study methodology'. Although general alliances did not impact the corporate value significantly, in the analysis corresponding to the alliance type, R&D alliances created positive value, as technology acts as an important factor for the alliance. Among the R&D alliances, 'Technology Transfer alliances', in particular 'Development Technology Transfer alliances', had a positive influence on the corporate value. We interpret these differentiated results as market tends to screen for types of alliances. Meanwhile, we confirmed that the possibility of a stock price increase before the alliance announcement is high by analyzing the impact of the timing of corporate alliance announcements on the company value. It can be inferred that the possibility of information leakage is high. This paper analyzes the impact of alliances for managers and practitioners seeking to create value for domestic bio-pharmaceutical companies, and suggests the need to prevent information leakages by establishing a suitable policy.
