Yoqurt products are known to be effective for enhancing health and preventing diseases such as cancers. Such effects are generally believed to be due to actions of polysacchmides in yoqurt products. In this study we have determined compositions of monosaccharides in hydrolysates of commercial yoqrtrt products as the first step of understanding structures of polysaccharides. The yoqtrrt products were ttltracentrifuged, filtered, hydrolyzed in 1M sulfuric acid and neutralized. A portion of the solution was taken and evaporated to dryness, denvatized with TMSI (trimethly- silylimidazole) and analyzed by GC/MS. We found that the monosaccharides were fructose, glucose, and galactose. Their compositions were variant among several yoqtrrt products.

It is almost impossible for firms to possess all of resources and capabilities needed to create technological innovations in modern competitive environment. This situation forces firms to conduct R&D collaboration. Therefore, this paper analyzes an effect of appropriability protecting knowledge exclusively on R&D collaboration and product innovation performance. In addition, we investigate how the governmental R&D support moderates and influences those relationships through empirical analysis. The results of moderated mediation show that the impact of appropriability on product innovation performance appears to be a common pattern in each conditional indirect effect of appropriability regardless of financial, direct, indirect R&D support of the government. The more governmental R&D supports increase over a certain level, the more conditional indirect effects of appropriability on product innovation performance increase through the vertical R&D collaboration. However, conditional indirect effects of appropriability through horizontal R&D collaboration are not significant in all levels of government R&D supports. If we utilize an analysis of moderated mediation by applying governmental R&D supports as a moderator, it is possible to analyze a significant strength of innovation policies and their performance. Therefore, this paper would make a contribution to an evolution of governmental R&D support and an effective formulation of innovation policy.

'Low Carbon, Green Growth' may be the achievable target in industry section, depending on whether less reliance on fossil-fuels use can bring higher productivity growth in the long run. This paper tests for the short-run and long-run effects of investment on energy-saving equipments on productivity growth in the Korean manufacturing industries. The investment in energy efficiency causes an increase in costs (measurement effect) in the short-run, but in the long-run likely improve energy intensity and reduce costs (positive real effect) despite the delay in new other investment for technical innovation (negative real effect). A 2SLS regression was attempted to deal with endogeneity of energy-saving investment. The productivity effects were tested for five manufacturing sub-industries showing relatively high energy intensity with annual time series data from 1982 through 2006. No productivity effects were accepted for all five sub-industries except Chemical products. Positive real effect was considered to be exceeded by negative real effect, resulting in decreased productivity growth for Chemical products.

This paper analyzed price asymmetry of domestic petroleum products by distribution stage. Analyzing the asymmetry by distribution stage, we can investigate the gap between analysis results and consumers' perception. For the first stage, we analyzed asymmetries between retail prices including tax and the spot prices of crude oil. The results show that retail price increases more quickly in response to the crude oil prices rise than to the crude oil prices fall as consumers' perception. For the second stage, we analyzed asymmetry of international petroleum product prices in Korean Won with the change in the crude oil spot prices. The results show that international petroleum product prices increase higher in response to the crude oil prices increase than to the crude oil prices decrease. For the final stage, we examined the asymmetry of wholesale price and retail price with the change in the international petroleum product prices in Korean Won. The results show that wholesale prices increase more quickly in response to the crude oil prices rise than to the international petroleum product prices fall. The retail prices, however, decrease more quickly in response to the crude oil prices fall than to the international petroleum product prices rise.

Better quality software can be made by eliminating the software product risk in the early stages. To achieve this task, a risk analysis system that can effectively track and manage risks that have severe effects on software quality is needed. The existing risk analysis systems have some weaknesses as they are applied to organizations. The major problems of those systems are that they require organizations to collect as much risk data at a time without providing a proper explanation and even without the support of a risk management process. This paper resolves those problems by developing a risk analysis system that offers methods of managing risks. In addition, the system provides the guidelines of which risks should be gathered for each step. The system also has functions to generate a range of strategy and analysis information on risks.

This study started from the point that female consumers have powerful effects on selection and purchase of products. Liquor is consumed by men more than women, but a population of women drinking liquor is increasing due to "wellbeing and a tendency to lower alcoholicity" of soju. Through priming effects, this study estimated and tested how liquor advertising which had been made focusing on male consumers could appeal to female consumers and affect their purchase. The results of this study revealed that the subjects were partially influenced by priming effects when the experimental image and the interference image were connected to each other in terms of their meaning. This study showed that if scenes in advertising, no matter how short they were, were in a similar situation, priming effects occurred and consumers had a positive attitude toward behavior which appeared in the advertising. In order that advertising of male-dominated products such as cars in addition to liquor may appeal to female consumers, situational factors have to be suitable to create priming effects. If such priming effects are advertising making and arrangement, advertising can appeal to female consumers more easily.

This study was conducted to identify the negative effects of sports sponsorships on consumer attitudes towards sports celebrities and the products advertised by them. The results of this study verified the main effects of sports celebrities' responsibility level on consumer attitudes toward the sports celebrity and his/her products in cases of negative incidents. Furthermore, the moderating roles of sports celebrities' response strategies were identified. Data were collected from 135 undergraduate students in the Republic of Korea using a questionnaire. The data from nine participants were discarded because of disingenuous answers to the questionnaire; thus, the final sample consisted of 126 participants. Multivariate analysis of variance (MANOVA) of the obtained data revealed that a sports celebrity's responsibility level has negative effects on consumer attitude toward the sports celebrity and the product. The moderating effects of the sports celebrity's response strategies were also significant.

Remanufacturing re-commercializes a used product to achieve an equal or higher performance level than the original product by disassembling, cleaning, inspecting, repairing, reconditioning, and reassembling the used product. The remanufacturing industry is a key industry necessary to realize carbon neutrality by 2050. This study uses life cycle assessment to analyze the resource reduction and greenhouse gas reduction effects with and without considering the avoided effect for an injector, which is an automobile part that is actively being remanufactured. The results of this study showed that the resource reduction effect and greenhouse gas reduction effect induced by injector remanufacturing were reduced by 95.30% and 93.88%, respectively, based on one unit without considering the avoided effect. However, when considering the avoided effect, which in this case is the environmental impact of not disposing of the used injector and not having to use natural resources to manufacture a new injector because the used injector was reused during remanufacturing, the resource reduction effect and greenhouse gas reduction effect were 190.91% and 188.33%, respectively. The results of this study are expected to be used in the future to evaluate the amount of environmental impact reduction while considering the avoided effect during remanufacturing and to help develop research methodology for remanufacturing.
