Palm Oil Fuel Ash(POFA),which is burned in palm oil factories to get energy and gathered, has been studied in many countries due to its chemical properties. However POFA has high value of LOI and lots of pores on its particle surface. Therefore, in this study, POFA's fluidity were confirmed by mini-slump test and plastic viscosity test. Through the results, fluidity of POFA reduced according to the replacement ratio of POFA because of high value of LOI and its pores on surface and plastic viscosity of POFA increased. In addition, when superplasticizer was added, fluidity increased due to the steric effect of polycarboxylate superplasticizer.

First, the study will establish the concept of Brand Values of Environmentally-friendly agricultural product through theoretical discussion. Second, it shows the effects of Environmentally-Friendly Agricultural Products brand value on Brand Satisfaction, Brand Trust and Brand Loyalty by empirical investigation. Third, in order to provide the methodology of brand development, literature regarding and questionnaire survey were used such as Environmentally-Friendly Agricultural Products Brand Value, Brand Satisfaction, Brand Trust and Brand Loyalty. Based up on the results, the research estimates consumers' relative priorities of Environmentally-Friendly Agricultural Products Brand Value factors in purchase. This research also suggests the consumer oriented new brand development and the progressive direction for the successful launching of Korean Environmentally-Friendly Agricultural Products Brand. Research design, data, and methodology - Because the relative literatures reviewed regarding not only each factor but also the relationships among them, Brand Value was categorized into 4 dimensions: Emotional, Social, Functional, and Epistemic Value. Then, Brand Loyalty was added as an outcome variable and Brand Satisfaction, Brand Trust were also added as mediators. The proposed research model and 13 hypotheses were created and 23 measurement items were developed. A face-to-face questionnaire survey with items concerning the Brand Value of Environmentally-Friendly Agricultural Products is conducted to housewives in metropolitan area in May 2016. Respondent answered about Brand Value, Brand Satisfaction, Brand Trust and Brand Loyalty in preferred Environmentally-Friendly Agricultural Products. 333 copies of the questionnaire were collected and analyzed using SPSS 21.0 and AMOS 20.0 to determine the reliability and validity of the measurements. Results - From the confirmatory factor analysis and a structural equation modeling, the outcomes of these studies were as follows; (1) Three Brand value dimensions, i.e. Emotional Value, Social Value, and Epistemic Value had a significant and positive impact on Brand Satisfaction, but Functional Value did not. (2) Social Value also had an impact on Brand Trust, (3) Brand Satisfaction significantly affected Brand Trust, and Brand Trust influenced on Brand Loyalty, and (4) Brand Satisfaction were perfectly effective in mediation between Emotional Value, Epistemic Value and Brand Trust, and it also partially mediated between Social Value and Brand Trust. Conclusions - According to the result of consumer research on Environmentally-Friendly Agricultural Product brand, 3 dimensions of brand value affected brand satisfaction, and especially Social Value was a significant positive dimension. So, marketers should concern about value proposition of Environmentally-Friendly Agricultural Product to consumers by using premium package design, store identity, and distinctive product. Consumers wanted to get self-esteem, self-regard, and high social position by purchasing it. This study has academic and practical significance, so the findings can be applied to a wide range of brand management strategies. However, there are some limitations; 1) limitation about development of new brand value dimensions, 2) limitation about gender in the area of respondents. Future research should be done with wide range of respondents.

In the presidential new-year address in January 2, 2009, the President declared that 17 kinds of new driving force of growth that could create high-added value be selected to step up job creation and an increase in national wealth. The Ministry of Strategy & Finance announced plans for the 17 kinds of new driving force of growth after the presidential address. Specifically, that ministry announced an ambitious plan to select health care service named 'Global Health Care' as one of the five service industries that could create high-added value in a move to provide jobs to approximately 7,000 people and produce pervasive economic effects coming up to a trillion and 10 billion won. To attain the goal, several action plans were mapped out to globalize domestic medical institutions, to rearrange the relevant law and system for the purposes of raising awareness of domestic medical institutions among foreign patients and improving their accessibility and post-satisfaction level, and to lure lots of foreign patients through financial assistance. At the same time, the government announced plans to lure severe patients such as those in want of surgery or organ transplant, cancer patients or patients with heart diseases to create high-added value on a long-term basis. Thus, the government announced that it planned to formulate such strategies and to enter an agreement with foreign governments to attract plenty of foreign patients. In fact, however, there are little full-scale evaluation of medical tourism though it's been a year since it was introduced, and there are few actual efforts to implement what the government announced, either. According to the results of the evaluation of medical tourism, domestic hospitals are said to undergo little significant changes after the introduction of medical tourism, which shows that they take a dim view of medical tourism instead of having expectations for that. The medical tourism industries in major Asian countries have been dynamized, and there are several factors of their success. First of all, they are successful in creating new market opportunities by incorporating related industries such as medicine, tourism and IT and in developing medical tourism products and differentiated marketing by taking advantage of their competitive edge. They have offered full-fledged assistance to this sector, and another reason is the improved international credibility of their medical service. If our country fails to pinpoint our problems in consideration of the cases of the Asian countries or to provide appropriate financial aid, our country is bound to lag behind them. Given this reality, how to assess medical tourism and what challenges this sector is confronted with are discussed.

This paper investigates the properties and relative importance of Apparel Textile industry of Busan in terms of both the number of employees and the value-added, and then analyzes the relative technical efficiencies from the perspectives of space closeness such as consumption market, suppliers, living standards and clustering environments using the DEA model. The main outcomes are as follows. The Apparel Textile industry is still a key industry in Busan with relatively high intensity and high LQ (greater than one) in spite of the recent decrease between 2000 and 2005 both in the number of employees and the value-added. Those firms with consumption market showed higher efficiency in all kinds of efficiencies than the firms without the market, and further relatively higher efficiency than the firms with suppliers. In addition, the firms located in the higher living standards also showed higher values of efficiency compared with the firms in lower living standards. The policy implication from the results is that the strategic and selective investment should be made according to the relative efficiency and thus the traditional industry should be transformed to the high value added one with additional investment to utilize the scale efficiency.

To increase the added value of peaches and utilize overproduced peaches, it is necessary to develop peach raw materials in various forms. In this study, usefulness of juice as raw material for vinegar was investigated by comparing and analyzing the characteristics of the traditional fermented vinegar prepared with 4 types of juice (fresh, refrigerated, boiled and frozen puree). Sugar content (6.20~6.50°Brix), total acidity (5.25~5.61%), pH (3.42~3.74), and acetic acid content (48.81~54.29 mg/mL) of the vinegar were all similar to existing traditional fermented vinegar. However, contents of total phenol and flavonoid were higher in vinegar prepared from refrigerated and boiled juice. Therefore, it was confirmed that boiled and refrigerated juice are very suitable as raw materials for traditional fermented peach vinegar, in particular, it was confirmed that boiled juice with a high content of total phenol and flavonoid can be used as a high value-added functional material. These results are considered to be important guidelines for developing high value-added raw materials for peaches.

Recently, cloud computing market is growing geometrically in both private and public area, and many global companies in various domains have developed and provided cloud computing services. In such situation, Korean government made multiple plans for domestic cloud computing industry. However, most research institutes have focused on market size and status information, which makes actual effectiveness of cloud computing service hard to recognize. In this study, we define cloud computing Industry by rearranging Input-Output table published by the Bank of Korea to use Input-Output Analysis. The Input-Output Analysis was devised in 1963 by Leontief and it is used in many fields of study until now. It produces various coefficients that are able to identify production-inducing effect, value-added effect, labor-inducing effect, front and rear chain effect. The analysis results show that production-inducing effect, front and rear chain effect of cloud computing industry is low compared to other industries. However, cloud computing Industry possesses relatively high value-added effect and labor-inducing effect. It is because industry magnitude of cloud computing is smaller than other industries such as manufacturing, chemical industries. The economic effects of the cloud computing industry are not remarkable, but this result is significant to emerging markets and industries and presents the fresh way of analyzing cloud computing research field.

Increasing numbers of value added chemicals are being produced using microbial fermentation strategies. Computational modeling and simulation of microbial metabolism is rapidly becoming an enabling technology that is driving a new paradigm to accelerate the bioprocess development cycle. In particular, constraint-based modeling and the development of genome-scale models of industrial microbes are finding increasing utility across many phases of the bioprocess development workflow. Herein, we review and discuss the requirements and trends in the industrial application of this technology as we build toward integrated computational/experimental platforms for bioprocess engineering. Specifically we cover the following topics: (1) genome-scale models as genetically and biochemically consistent representations of metabolic networks; (2) the ability of these models to predict, assess, and interpret metabolic physiology and flux states of metabolism; (3) the model-guided integrative analysis of high throughput 'omics' data; (4) the reconciliation and analysis of on- and off-line fermentation data as well as flux tracing data; (5) model-aided strain design strategies and the integration of calculated biotransformation routes; and (6) control and optimization of the fermentation processes. Collectively, constraint-based modeling strategies are impacting the iterative characterization of metabolic flux states throughout the bioprocess development cycle, while also driving metabolic engineering strategies and fermentation optimization.

For biotechnological production of high-valued ${\beta}-{\text\tiny{D}}$-hexyl glucoside, the catalytic properties of Hanseniaspora thailandica BC9 ${\beta}$-glucosidase purified from the periplasmic fraction were studied, and the transglycosylation activity for the production of ${\beta}-{\text\tiny{D}}$-hexyl glucoside was optimized. The constitutive BC9 ${\beta}$-glucosidase exhibited maximum specific activity at pH 6.0 and $40^{\circ}C$, and the activity of BC9 ${\beta}$-glucosidase was not significantly inhibited by various metal ions. BC9 ${\beta}$-glucosidase did not show a significant activity of cellobiose hydrolysis, but the activity was rather enhanced in the presence of sucrose and medium-chain alcohols. BC9 ${\beta}$-glucosidase exhibited enhanced production of ${\beta}-{\text\tiny{D}}$-hexyl glucoside in the presence of DMSO, and 62% of ${\beta}-{\text\tiny{D}}$-hexyl glucoside conversion was recorded in 4 h in the presence of 5% 1-hexanol and 15% DMSO.
