The objective of this research was to determine the effect of waste nutrient solution (WNS) on growth and development of poinsettia 'Gutbier V-10 Amy'. To achieve this, WNS collected from rose grown in greenhouse was diluted with various times and 500 mL of each solution was applied every week. Then growth characteristics and nutrient uptake were determined at 180 days after transplanting. The treatment of undiluted WNS had highest plant height and length of branch among treatments tested, but there were no statistical differences in the number of bract and branches. Undiluted WNS had higher leaf number, leaf length, leaf width, fresh weight, and dry weight than any other treatments tested. There was also a trend that increased dilution times of WNS resulted in decreased plant growth. Undiluted WNS had higher chlorophyll content than Hyponex treatment, but diameter of crown did not show significant differences among treatments. In the analysis of root media collected at 6 months after fertilization, the treatment of undiluted WNS had higher electrical conductivity and organic matter content than other treatments, but the Hyponex treatment had higher phosphorus concentration than other treatments tested.

This study was conducted to investigate the nutrient components and physicochemical properties of general ('Superior') and colored potato. Proximate composition, reducing sugar, free sugars, free amino acids, organic acids, minerals were analyzed, and Hunter color values were measured in the study. 'Rose' and 'Blue' (colored potatoes) contained high levels of reducing sugar, and total free sugar content was greatly different according to varieties. Glutamic acid, arginine and ${\gamma}$-aminobutyric acid were detected to be the three major amino acids in colored potato, and the major organic acids of general potato were oxalic acid, tartaric acid, malic acid and citric acid. All potato contained high level of potassium, calcium and magnesium. The Hunter 'L' value was the highest in 'Jaseo'; Hunter 'a' value was high in 'Blue' and 'Jasim'; Hunter 'b' value was the highest in 'Haryoung'. Overall, colored potato had higher amount of nutrients and physicochemical properties than 'Superior'. Therefore, colored potatoes are expected to be highly valuable items for the development and applications of a functional food. In addition, these results will provide fundamental data for improving sitological value, breeding of new cultivar and promoting of roughage usage.

Several reports indicated that astaxanthin and zeaxanthin have more active anticancer activity than pro-vitamin A carotenes. ${\beta}$-carotene hydroxylase is a key enzyme to synthesize zeaxanthin and astaxanthin in carotenoids biosynthesis pathway. We isolated the ChyB gene encoding ${\beta}$-carotene hydroxylase from tomato leaves. The ChyB gene (1.5Kbp) fragment was cloned into the binary vector and designated to pIG121-ChyB-tom. Agrobacterium-mediated infiltration was used for transient assay in Nicotiana benthamiana. Leaf samples were collected 0, 1, 2, 3 days after infiltration (DAI). RT-PCR result showed that the expression of ${\beta}$-carotene hydroxylase transcripts was not detected in control (0DAI), but its expression was detected after 1 DPI and increased later on. When the activity of ${\beta}$-carotene hydroxylase was measured, the 1,1-diphenyl-pricryl hydrazyl (DPPH) radical scavenging activity (27%) at 2 DAI was significantly higher than that (21%) at 0 DAI. These results indicated that anti-oxidant activity dramatically increased at 2 DAI in tobacco leaves was due to over expression of tomato ${\beta}$-carotene hydroxylase. These results can be the foundation to develop tomato cultivars with high oxy-carotenoids content using the ChyB gene transformation.

In general, a venture capital invests in tech startups and helps them improve the corporate transparency through board of directors. With respect to venture capital investment and its impact on the corporate transparency of the newly public firms from 2004 to 2010 in Korea, we have made regression analysis. First, it was found that it was likely to be less transparent, the larger its asset size or the higher its debt ratio was. Second, lower level of ownership-control disparity resulted in higher transparency. Third, a shorter period to IPO and higher growth rate were more prominent in companies with lower degree of transparency. The above findings were not conclusive to prove whether or not venture capital directly increases the transparency level of its portfolio companies, but do insinuate the possibility of a negative impact on the transparency of its investee companies, as early IPO's were associated with less transparency. This is all the more persuasive as it was observed that companies with a lower level of transparency had generally raised more money from venture capitals, and that companies with a higher growth rate and/or higher PBR, have shown to be less transparent.

This study was conducted to establish a service philosophy as a major ideology in the New Economy and Society. The service philosophy, which is the ideological foundation to lead the service economy era, should be an idea that can develop the new economy society, reflecting the nature principle of the universe and human being. The service philosophy was derived based on the study of the human representative ideology and the study of the new economy and service essence. A good idea must be consistent with the principles of the universe and be consistent with the essence of the human representative ideology, so that it reflects the core principles of the universe and the core of human representative ideas. In addition, the central idea should reflect the changes of the New Economy Society in the future. Therefore, the essence of the service and the change of the New Economy Society were analyzed. We analyzed the social and philosophical significance of the macroscopic cosmology and the microscopic quantum theory of modern physics. We analyzed the essence of Oriental and Western representative ideas and derived implications of these ideas from the viewpoint of modern society where service is central. Based on the essence principle of the universe and human, we have established the service philosophy structure and derived the human, historical, social, economic, and managerial aspects of service philosophy. The structure of the derived service philosophy was presented, and discussions were conducted for future research.

Despite the increasing importance of information technology in firms, the extent to which IT governance are established varies widely across the firms. To perform desirably the role of IS needed in most companies, high level of IT governance and the effective management should precede. However, the impacts of such activities and management on the IT governance have not been empirically examined in depth until now. Thus, building on the theory of governance and the institutionalization, the research model and the hypotheses of the study were formed and then empirically tested. The study used a survey of senior IT managers from 108 firms in order to examine hypothesized relationship among the following constructs: strategic alignment, IT governance committee, IT planning, EA, PMO, SLM, IT compliance, incident management, IS effectiveness, visibility, and corporate performance. A structural equation model is developed by using LISREL to assess the relative effects and interrelationship among these constructs. The results show that strategic alignment has positive influence on IT governance committee and IT planning. IT governance committee, IT planning, SLM, incident management from IT governance activities have positive effects on IS effectiveness, whereas IT compliance has a negative effect on IS effectiveness. Visibility is positively influenced by IT planning, EA, SLM. IT compliance, and both IS effectiveness and visibility have positive effects on corporate performance.

In this paper, we build a gradient Boosting model to predict government SME R&D subsidy, select features of high importance, and measure the impact of each features to the predicted subsidy using PDP and SHAP value. Unlike previous empirical researches, we focus on the effect of the R&D subsidy distribution pattern to the incentive of the firms participating subsidy competition. We used the firm data constructed by KISTEP linking government R&D subsidy record with financial statements provided by NICE, and applied a Gradient Boosting model to predict R&D subsidy. We found that firms with higher R&D performance and larger R&D investment tend to have higher R&D subsidies, but firms with higher operation profit or total asset turnover rate tend to have lower R&D subsidies. Our results suggest that current government R&D subsidy distribution pattern provides incentive to improve R&D project performance, but not business performance.

This study was designed to develop dish recipes using Heatsun sprouts to improve the sprouts' utilization and consumption. We created four kinds of dishes with Heatsun sprouts, including Acanthopanacis cortex, Kalopanax pictus, Aralia elata, and Cedrela sinensis, and analyzed their sensory properties and nutrients. In the sensory evaluation, the overall preference for all the dishes was scored higher than 3.0, Unnaumsun-dakgoginaengchae had the highest score (4.48) among the dishes. Unnamusun-dakgoginaengchae contained higher values of protein; vitamin A, E, and B6; and folic acid than the recommended dietary allowances (RDAs). The recipe for Dureupgokgammuchim was created to reduce the bitterness and the astringent taste of Aralia elata, and it was rich in vitamin C, E, and B6, as well as in folic acid and iron. Ogapisunkkonchijolim was cooked to reduce the fishy smell of a saury with the addition of Acanthopanacis cortex. It contained 1.5 times the protein RDAs, and high levels of antioxidant vitamins, including vitamin A, C, and E. Chamjugmandu was made by the mixing tofu and various vegetables without adding meat. It had the highest calorie count among the dishes, and its vitamin A, C, and E contents were higher than the corresponding RDAs.

Induced from government policy to boost regional economic competitiveness, regional informatization forming e-community has been the subject included in the various regional informatization master plans in Korea. However, few cases are reported for its successful implementation mainly due to the lack of profitable business model to encourage investment. On the other hand, most efforts to build smart apartments, part of the home networking in a broad sense, has been pursued from the different directions. Telecommunication giant such as Korea Telecom tries to find new source of revenue exploiting enhanced broad band technology. Also, construction companies started constructing housing complexes equipped with built-in high speed network infrastructure as a means to differentiation to other competitors. The contents providing community portal has become mandatory in the sense of bearing the cost from customer side who are willing to adopt those services for new smart house. Our research motivation stems from exploring critical value aspects of realizing the profitability of this emerging new business model, that is, industry convergence model. In this paper, mainly from the survey results of the Korean smart apartment complexes, we reported recent home networking services development in Korea, and value propositions from the business model perspective. Merged business model components of telecommunications, construction, and internet contents are analyzed to provide the insights for future directions.
