The quality characteristics, total phenolic content, anthocyanin content, and DPPH radical scavenging activity of rice nutritional bar with added powder of aronia byproducts were investigated in this study. The rice nutritional bar was prepared by adding aronia byproducts powder at concentrations of 0%, 2%, 4%, and 6%. The pH of the rice nutritional bar batter was lowered for the control and 2% aronia byproducts powder was added. The moisture content, baking loss rate, leavening rate and specific volume of the rice nutritional bar decreased with as the aronia byproducts powder content increased. In relation to measurements of the colors of the rice nutritional bar crust and crumbs, as the content of aronia byproducts powder increased, the L and b values decreased while the a value increased. From texture analysis, the hardness and chewiness increased according to the level of added aronia byproducts powder, but the springiness and cohesiveness decreased. The total phenolic content, anthocyanin content, and DPPH radical scavenging activity showed the highest values in the rice bar with 6% aronia byproducts powder added. According to a sensory evaluation, overall preference was highest for the rice bar with 4% added aronia byproducts powder, whereas the color and taste was rated higher for the rice bar added with 4% and 6% aronia byproducts powder.

The emergence of smart devices and IoT leads to the appearance of O2O service to blur the difference between online and offline. As online services' merits were added to the offline market, it caused a change in the dynamics of the offline industry, which means the offline-space's digitization. Unlike these changing aspects of the offline market, exhibition industry grows steadily in the industry, however it is also possible to create a new value added by combining O2O service. We conducted a survey targeting 20 spectators in '2015 Seoul Design Festival' at COEX. The survey was used to analysis of the spatial structure and generate the dataset for machine learning. We identified problems with the analysis study of the existing spatial structure, and based on this investigation we propose a new method for analyzing a spatial structure. Also by processing a machine learning technique based on the generated dataset, we propose a novel evaluation model of exhibition-space cells for O2O service layout.

This study compares the economic impacts among ICT sectors and derives strategic considerations for development of the ICT industry in Korea. Prior to analysis, this study classified ICT industry into four sectors: ICT equipment, components, service, and SW/system. This study conducted Input-Output Analysis on the four ICT sectors. An Input-Output Analysis is a quantitative economic technique that represents the direct and indirect interdependencies between different industries of a national economy. Features of each ICT sector were observed in the results. Within the ICT equipment sector, production is decreasing, import dependence is increasing, and employment size is very low, relative to the overall ICT industry. The component sector accounts for the over half of the output and value added of the ICT industry, but domestic production has recently declined. The subsector experienced decreasing production and increasing imports relative to the other ICT subsectors. In the service sector, output is small but its production and employment impact is very high. The fourth sector, ICT SW/system, has very low impact on production but high impact on employment. These features suggest two strategies to develop the ICT industry in Korea. First, the ICT component and service sectors should be promoted to stimulate growth of the national economy. Second, to encourage employment growth, policies should promote the ICT SW/system and service sectors.

Current Internet services do not consider the service level interoperability because each service is developed with its own interface, which is not compatible with other services. This means that characteristics of Internet services are autonomous and heterogeneous. Moreover each service has its own access method, data representation, and data structure. This will make it difficult for NGN services to be converged. For the convergence scenarios of NGN services, interoperability among different applications shall be supported in service layers in various network environments. In order to realize this, integration function in applications is necessary. And, it is also required that NGN services shall consider to adopt the conventional E-business framework such as ebXML in order to create value added services.

Added value of music industry in Korea is not distributed and calculated properly, and this obstacle brings various problems in a creative environment. Meanwhile, a new business model such as Open Collaboration, Crowdsourcing and platform that makes decisions and innovation from external resources has been appeared in commercial area. This new model like a composer delivers to consumers directly through Youtube.com, and multi collaboration is applied to the music industry, and it enables a new type of mechanism for creation, distribution, division, and calculation of music. However there are not enough empirical study of the music market because existing relative researches has been centered around fundamental concepts and application methodologies. This research defines Open Collaboration Platform in the music industry, and studies affecting factors of Participation Intention for example Justice, Information System Quality and Perceived Value. For a survey we apply PLS(Partial Least Square) to analyse Equity, Information System Quality and structural equation between Perceived Value and Participation Intention. Analysis results show Distributive Justice and Procedural Justice affects Platform Trust, and Service Quality, Economical Value and Emotional Value affects Platform Usefulness. Also Platform Trust and Platform Usefulness affects Platform Participation Intention. We discussed academic and practical implication based on research results.

This study produced instant Gochujang(red pepper paste) with enhanced convenience by increasing nutritional value and palatability, and by reducing production period, adding in the red pepper seed in the red pepper paste production in order to increase the use of the red pepper seed that is not used often as a food ingredient even though its nutrition value when producing red pepper paste was proven. Moisture content, pH, L-value, a-value, b-value, sugar contents, and salinity of instant Gochujang tended to increase as the amount of red pepper seed increased, while viscosity manifested the opposite trend. Sensory evaluations were conducted on instant Gochujang to assess differences in characteristics, which demonstrated that as the amount of red pepper seeds powder increased, the intensity of redness for the red pepper paste's external appearance, luster, spicy flavor and taste, and savory taste were evaluated strong. Meanwhile, fermentation value, which is red pepper paste's foremost weakness was evaluated as weak. Moreover, there was no difference in the size of the grain when compared to the contrast group consisting of regular red pepper paste. The results of preference test demonstrated that the RG3 with 30% of red pepper seed is optimal in terms of the external appearance, taste, texture and overall preference.

The economic effects of sewage and wastewater treatment service (SWTS) sector on other sectors have been rarely investigated in the literature. This paper attempts to apply an inter-industry analysis to looking into the economic effects of the SWTS sector. To this end, the most recently published 2012 input-output table is used here. In particular, the SWTS sector is specified as exogeneous to identify the economic effects of the SWTS sector on other sectors. Production-inducing effect, value-added creation effect, and employment-inducing effect are quantified based on demand-driven model. Supply shortage effect and price pervasive effect are also analyzed employing supply-driven model and Leontief price model, respectively. The results show that production-inducing effect and value-added creation effect of a unit of investment or production in SWTS sector are estimated to be 1.7076 and 0.7392, respectively. The employment-inducing effect of one billion of investment or production in the SWTS sector is computed to be 11.0498 persons. The shortage effect of the SWTS sector amounts to 0.8417 won. The overall price effect of the 10% increase in the price of SWTS sector is calculated to be 0.0115%. This quantitative information can be utilized in predicting the economic effects of the SWTS sector-related activities or policy-making.

The present study made an empirical analysis for investigating the competitiveness of technology trades in Korea. In particular, the study deduced the correlation between technology export and technology import using the variables of Gross Domestic Expenditure on R&D and Per capita industry value added Productivity and employed fixed effect model in panel linear regression model. It is found that the R&D expenditure of OECD countries made a significant effect on the technology import and the value-added labor productivity made a significant result on both technology export and import. Therefore, it showed that the technology trade in Korea made a sensitive response to labor productivity in OECD countries. By panel analysis, machine, construction, ICT, and service industry affect most on technology export in Korea for recent 5 years. For technology import, electric-electron, chemical, service, and construction industry have significant effects. This study contributed to understanding of industrial characteristics affecting technology trades in Korea and empirical analysis to show correlation between the factors affecting technology trade.
