A new design field called eDesign appears as if eBiz is an online related business in which an industrialized design creates the individual value added facing a digital revolution. The field of eDesign requires a special design process and management methodology regardless of the fact that human sensitivity will be satisfied through a dehumanized computer technique. However, it is the reality of eDesign that has been dependent upon a simple process or project management tool of general design. In this study, we develop an eDesign platform based on an eDesign process and template mainly focused on eBusiness in order to overcome the wrong situation. The template is a kind of document that has a standardization form. We aim to establish a general process through various case projects, store information using a necessary template, and use for the way of visual communication. We propose a standard of eDesign platform that can be widely applied to the field of design, medium and small enterprises focused on IT businesses or design-team through this project performed as an educational-industrial study. It makes it possible to get a detailed process methodology, which can be applied to many small design related companies that don't have their own process yet, and will be a scale for comparing their own process in which the company has a process of opened standard eDesign with it. In addition, it makes possible a systematic control of the own projects within and outside the firm, accumulating information for the firm through the database, and easy communication. Furthermore, it can be applied to check the process of the project as a checklist, and then it will reduce trial and error repeated for every project that has been done.

This study was performed to develop functional vinegar by using cucumbers through two stages of fermentation. The alcohol content was maximized (7.8%) after 6-days of alcohol fermentation at $25^{\circ}C$ by adjusting the initial sugar concentration to $15^{\circ}Brix$, and vinegar with an acidity of 5.8% was obtained after 12-days of acetic acid fermentation at $30^{\circ}C$. The major sugars in the produced vinegar were glucose and fructose, which were present in concentrations of 3,067.26 and 395.73 mg%, respectively. The major organic acids were acetic acid and succinic acid, which were present in concentrations of 4,410.5 and 841.11 mg%, respectively. The total free amino acid content of the cucumber vinegar was 181.45 ${\mu}g/mL$ and citrulline, valine, aspartic acid, asparagine, and ornithine were the major amino acids. The inorganic components included various alkaline elements, such as K, Ca, and Mg. In addition, experimental methods to assess the DPPH and $ABTS^+$ radical-scavenging ability, reducing power, and ${\beta}$-carotene bleaching activity showed that the cucumber vinegar had strong antioxidant properties. The total polyphenol content, which are the major components responsible for the antioxidant activities of the cucumber vinegar, was 40.14 mg/100 mL. The cucumber vinegar showed significantly higher hepatic aldehyde dehydrogenase activity when compared to the alcoholic control (negative) and the marketing drink (positive), resulting in decreased plasma acetaldehyde concentrations in rats. These results demonstrate that cucumber vinegar possesses antioxidant properties and holds great promise for use in preventing hangovers.

The world demand of ethanol as an alternative fuel for gasoline is increasing rapidly because of high oil price and global climate change. Most of ethanol is currently produced from corn grain or sugars in sugarcane and sugar beet. Because these sources compete with foods and animal feed and are not expected to be enough for future demand of ethanol. Thus, cellulosic ethanol from agricultural residues or wood has to be commercialized in near future. Typical cellulosic ethanol production consists of pretreatment, enzyme hydrolysis, fermentation and product separation. This paper reviews the principles and status of each step and discusses issues for cellulosic ethanol production.

This study was conducted to investigate the difficulties of dairy farms in practicing 6th industrialization and methods for overcoming these difficulties. A qustionnaire survey was carried out to examine the present states of farms, recognition of the farmstead milk-processing market situation, possibility of farmstead milk processing for reducing the raw milk surplus, assessment of government policies, and difficulties dairy farmers confront in realizing the 6th industrialization. Farm sizes, types, and human resources organizations varied between farms. Most farmers were producing yogurt and/or fresh (string or barbecue) cheeses, which were marketed through 'Visit and Purchase' channel. Farmers who answered the questionnaire were relatively positive about the current situation of farmstead milk processing, expecting to be involved in the disposal of excess raw milk. Nevertheless, they responded negatively about current relevant policies, citing the main difficulties caused by 'excessive regulation'. Other barriers to successful '6th industrialization' are difficulties in marketing and lack of funds. Approximately 19% of dairy farms practicing the '6th industrialization' use automatic milking system (AMS) and 38.46% of dairy farmers whose milking depends on conventional milking system intend to introduce AMS in the future. Positive expectations of AMS adoption were mostly related to 'lack of time and labor', 'exhibiting for tourism', and 'succession of dairying'.

The biological activities of extracts from Rubus coreanus Miq. were compared. About 70% of the growth of human hepatocarcinoma and 79% of human gastric cancer cell was inhibited in adding 1.0 mg/ml of the extracts of Rubus coreanus Miq. respectively. The growth of human breast cancer cells was also inhibited in adding 1.0 mg/ml of the extracts as well as 78% of the human cancer cells. It was proved that the growth of human normal lung cell, scored as 15% for the extracts. Overall selectivity of the extracts on several human cancer cell line was over 5, which is higher than those from the Rubus coreanus Miq. The growth of both human immune B and T cells was enhanced up to 1.4 to 1.8 times by adding the extracts, compared to the controls. The secretion of tumor necrosis $factor-alpha(TNF-{\alpha})$ from T cell was also increased up to 78.8 pg/ml in adding the ethanol extract (0.5 mg/ml). Ethanol extract also increased up to about 70 pg/ml of interleukin-6(IL-6) from B cell. For screening regulate function of blood pressure, angiotensin converting enzyme(ACE) activity was inhibited up to 25% by adding the ethanol extract (1.0 mg/ml). In testing the hypoglycemic activity, 20% of ${\alpha}-glucosidase$ activity was inhibited for the extracts (0.5 mg/ml). GST activity was increased in the range of 1.2 to 1.6 times by adding extracts.

Purpose: Medicinal herbs have recently attracted attention as health beneficial foods and source materials for drug development. Recent studies have demonstrated that extracts of Lycium's fruits and roots have a range of physiologically active substances. The extract of Lycium's leaves has been reported to have excellent anti-oxidant and anti-microbial activity, but its anti-inflammatory efficacy is not known. The chlorophyll present in the leaves can act as an anti-oxidant or pro-oxidant depending on the presence of light. Therefore, this study analyzed the anti-inflammatory effects of Lycium's fruit extract (LFE), leaf extract (LLE), and leaf extract with chlorophyll removal (LLE with CR). Methods: This study examined the inhibitory effects of LFE, LLE, and LLE with CR on pro-inflammatory mediator production as well as on the expression of iNOS and COX-2 in lipopolysaccharide (LPS)-stimulated RAW264.7 cells and BALB/c mice. Results: LFE, LLE, and LLE with CR inhibited the production of pro-inflammatory mediators (NO, $TNF-{\alpha}$, IL-6, and $IL-1{\beta}$) and the expression of iNOS and COX-2 in LPS-stimulated RAW 264.7 cells in a dose-dependent manner. Furthermore, the administration of LLE and LLE with CR inhibited the serum pro-inflammatory cytokine levels and suppressed DNA damage in BALB/c mice. In particular, LLE with CR exhibited the highest anti-inflammatory activity. Conclusion: These results suggest that the fruit and leaves of Lycium are potential therapeutic agents against inflammation.

To reduce the environmental contamination and to utilize fly ash massively produced from the coal power plant every year, we synthesized the artificial zeolite using fly ash treated with alkaline, and then analyzed the mineralogical and morphological properties by X-ray, IR, and SEM. The amount of $NH_4{^+}$, $K^+$, and $H_2PO_4{^-}$ adsorbed by the fly ash and the artificial zeolite were determined with reaction time, amount of adsorbate used, ion concentrations. The results obtained from the pot experiments packed with the top soil, amended with granulated artificial zeolite which was made by treatment of 4% polyvinylalcohol, showed that CEC of the artificial zeolite was $257.7cmol^+kg^{-1}$, that was almost 36 times greater than that of fly ash. The ratio of $SiO_2/Al_2O_3$ decreased but the amount of Na increased. The physico-chemical properties analyzed by X-ray, IT, and SEM represented that the artificial zeolite synthesized had a similar morphological structure to that of the natural zeolite. The structures of the artificial zeolite had a significantly enlarged surface having a lot of pores, while the fly ash looked like spherical smooth shape with having not pores on the surface. Thus, the artificial zeolite was successfully synthesized. The results of adsorption isotherms of fly ash and artificial zeolite showed that the amount of $NH_4{^+}$, $K^+$, and $H_2PO_4{^-}$ adsorbed increased as the equilibrium concentration increased, while $NH_4{^+}$ was strongly adsorbed on the surface of fly ash and artificial zeolite than that of $K^+$. The most distinctive growth of Chinese cabbage was found from the top soil(NPK + soils + 20% of granulated artificial zeolite + 5% of compost). Therefore, we concluded that one of the most effective methods to effectively recycle a fly ash was to make the artificial zeolite as we did in this experiment.

We develop a model to estimate the value of growth opportunities, which is based on the seminal papers of M&M(1961, 1963) and Lee(2006). Making use of the estimation model, we estimate a new proxy variable of the growth opportunities, other than the usual proxy variables such as quasi Tobin's Q, MBR, and so on. The new proxy variable of growth opportunities can represent a necessary condition to identify whether the increase in new investments are successful or not. The empirical findings on the growth opportunities during the IMF currency crisis period and the post-IMF period are as follows; First, the overall success rate of new investments is as low as 50%, that means only half of the listed firms were increasing new investments when they had the growth opportunities. Second, during the crisis, one third of the listed firms were experiencing negative growth opportunities. However, during the post-IMF period, the growth opportunities on new investments were turned to be positive due to the turnaround efforts of listed firms. Third, the value of intangible assets, which are resulting from the investment of R&D and human capital, are becoming more important than ever. It seems to be true that larger portions of the value of growth opportunities are coming from the intangible assets, not from the increases in new investments of the physical assets.

In general, content business companies include animation industry can have benefits, which they have higher incomes when they obtain wider markets. Therefore, they pursue to have diverse windows for content distribution or to reach the foreign markets for dealing their content products with potential customers. It have the greatest value. They can re-invest the incomes to produce their new products, and they can enhance the international competitiveness of their next products. As the results, the companies can have more incomes and wider markets in next business, and it will be the effectiveness of the good cycle of the animation industry. Animation industry has being undergone of its structure changes, more economical chances and viewers' attitudes changes through the all over the industry because of the acceptance of new digital technology. To response the changes or have the new chances from the changes, they should to review the existing system and the law concerned with the animation business as well as having the diverse new plans for supporting the industry like a construction of the online marketplace of Korean animation. It would make the Korean animation companies to meet foreign customers easily by making lower the entrance barrier of the foreign markets. Current Korean government needs to estimate the value of the Korean animation accurately and objectively by concerning its surroundings to support efficiently. However, it is very difficult to estimate the value of the content rightly because of its' intangible and subjective matter. For this, they should analyze the all the data of the information of the Korean animation content by accumulate, open to the public and manage. So if the government makes online marketplace for the Korean animation, which all the Korean animation companies get in, it would be a solution of estimating the value of the Korean animation rightly. In addition, it will be used as the role of archive of the government to lead the industry successfully. As a point of the small size of the Korean animation companies, they are government dependable because of its low budget, so they strongly expect the government to do the right role as the unique knowledge distributor. Therefore, the Korean animation online marketplace would make not only big companies, but also small companies to have the chances to increase the value of their content in the global markets by themselves without economic burdens.

Korea has accomplished rapid industrial development based on the manufacturing industry. However, the growth potential has been slowing down lately due to some reasons including low employment creation rates. Also, competitions in the manufacturing industry with China and developing countries in Asia are constantly intensified. Advanced countries maintain economic growth based on the competitiveness secured by changing its industrial structure into service oriented economy. Accordingly Korean government announced various policies to promote service industry and stimulate R&D activity for the advancement of knowledge based service industry. For promoting R&D of private firm, R&D center accreditation system for knowledge based service firm is going to be introduced. However, the accreditation system needs to be revised because it was established based solely on manufacturing business. Under the existing system, subject firms for government support are selected based on R&D activities. However in service area, the difference between R&D activity and business activity is indistinctive due to its nature so that the range of subject firms can be expanded too much. So it is more practical to select major service businesses and operate the system with selected businesses. There also should be proper logic to select major service business from the whole service businesses. We have to consider Koean industrial structure which is heavily dependent on manufacturing business and has weak competitiveness in service business when preparing the logic. In this paper, we study how to set up the range of service business and the requirements for R&D center accreditation. For this, this paper analyzed the ripple effect on the economy of service businesses based on input-output analysis, R&D activity and capability to put the resource for R&D. Based on the analysis result, we suggest methods to screen subject companies for R&D center accreditation among service business and present possible measures on manpower and physical requirement for service industry's R&D center accreditation system.
