This research attempts to analyze brand placement in game. Brand placement, being acclaimed as a new beneficiary model in game industry, is raising important mean of advertising. For development of game industry, the interdisciplinary study between game and advertising is indispensible. Therefore, the purpose of this study is to find creative types of brand placement in game for illuminating how advertising works in game contents. The results showed three types of brand placement in game. They are contextual type, prominent type and independent type. Contextual type is one where the brand is present within the game contents without being formally expressed: it plays a passive role. Prominent type is one where the brand is present within the game contents with being formally expressed: it plays an active role. Independent type is one where the brand is present within the game contents with being formally expressed but it is not related with the program: it plays an additional role. The research showed, among these three types, a prominent type is becoming mainstream of brand placement in game. In other words, the prominent type of brand placement is the most effective beneficial alternative in game industry.

Recent gut microbiota studies have revealed the important roles of gut microbiota for our health. Increasing numbers of health functional foods have been developed every year. Development of functional food often includes ex- and in-vivo experiment to verify the beneficial effects of the functional food. To investigate effects of functional food on gut microbiota, animal models were often conducted. Beneficial effects of food can be evaluated based on how gut microbiota was shifted by food, which results in either increase in beneficial bacteria, decrease in potentially pathogenic bacteria or both. As animal experiments are generally time-consuming and laborious, we investigate how well in-vitro investigation of fecal microbiota may reflect dietary health benefits. Here, we tested 15 kinds of diets using two human subjects' fecal materials. Our results showed varying gut microbiota shifts according to diets, which suggested generally known beneficial diets (i.e. Kimchi, Chunggukjang) increased Lactobacillus and Bifidobacterium. Therefore, we suggest that in vitro fecal microbiota analysis could be used to evaluate beneficial effects of diets. Moreover, this method may be ideal to establish personalized diet.

Flavobacterium is a genus within the phylum Bacteroidota that remains relatively unexplored. Recent analyses of plant microbiota have identified the phylum Bacteroidota as a major bacterial group in the plant rhizosphere. While Flavobacterium species within the phylum Bacteroidota have been recognized as pathogens in the aquatic habitats, microbiome analysis and the characterization of novel Flavobacterium species have indicated the great diversity and potential of their presence in various environments. Many Flavobacterium species have positively contribute to plant health and development, including growth promotion, disease control, and tolerance to abiotic stress. Despite the well-described beneficial interactions of the Flavobacterium species with plants, the molecular mechanisms and bacterial determinants underlying these interactions remain unclear. To broaden our understanding of the genus Flavobacterium's role in plant health, we review the recent studies focusing on their ecological niche, functional roles, and determinants in plant-beneficial interactions. Additionally, this review discusses putative mechanisms explaining the interactions between plants and Flavobacterium. We have also introduced the importance of future research on Flavobacterium spp. and its potential applications in agriculture.

In this study, the securing state of nationally indicated beneficial microbial resources was evaluated in an aspect of bio-diversity using their taxonomical information. Depending on the analysis result with the Margalef's richness or the Mehinick's index which are representative bio-diversity analytical indices, species diversity values was revealed as 8.537, 3.546 within bacterial resources, 3.349, 2.167 within fungal resources. Several developed or researched beneficial strains and spoilage microbes showed relative taxonomical relationship with comparation of their biological information. As a result, we propose the necessity or countermeasure method for preventing the microbial spoilage with the overhauling consideration of advanced research on agricultural microbiology covering crop endophyte beneficial/spoilage microorganisms.

Food consumption trends in Korea are becoming more health-oriented, and consumers have become interested in high-quality foods that are also beneficial to health. The goals of this study are to examine consumers' impressions of black garlic and to investigate the preferred optimal attribute combinations related to black garlic. To do this, a survey of 352 consumers was used to analyze the current status of consumer purchases of black garlic. A conjoint analysis was conducted to analyze certain aspects of consumer preferences, such as price, health functional food certification status, processing type, and taste. Consumers' purchase experiences with black garlic were relatively few, but those with purchase experience reported that they consumed it mainly for their health. The results show that consumers are not satisfied with the taste and flavor of black garlic despite their perceiving it as a beneficial food for health. Despite the fact that consumers' purchase intentions were found to be low, it can greatly increase if improvements in price, flavor, and taste can be realized and if offering substantial benefits. The results of the conjoint analysis of the preference attributes of black garlic products are as follows. Consumers considered price among the four attributes as most important. The taste of black garlic and the processing style were similar in terms of importance, and health functional food certification was less important. Finally, the results suggest that continuous improvements in price and flavor are needed to spread the consumption of black garlic.

Fermented foods have been recognized as functional foods that provide health benefits, including the modulation of intestinal microbiota. Therefore, the aim of the present study was to examine the effects of coffee beans fermented with Lactobacillus plantarum and Bacillus amyloliquefaciens on healthy human gut microbiota. Fermentation increased the content of beneficial substances (i.e., flavonoids and polyphenols). The consumption of fermented coffee increased the occurrence of beneficial microorganisms such as fiber degraders and short-chain fatty acid producers, although no significant microbiota shifts were observed after the coffee consumption. The analysis of metabolic activities also showed no difference after the coffee consumption. Our study demonstrates that the consumption of the fermented coffee may increase some beneficial bacterial while remaining the gut microbiota and its activities.

This paper proposed an environmental standard far beneficial use of dredged materials currently considered as waste materials. In Korea, even though chemical analysis of sediments are carried out frequently, their analysis results were not interrelated with the effects of biological lives due to a shortage of data, which may result in difficulty to develope Korean standards for reusing dredged materials. For these, this paper first searched existing foreign standards, analyzed local contaminated sediment data, identified their main components of contaminations and then compared clean-up standards of sediments consisting of lower and higher level. From these analyses new environmental standards considering Korean domestic circumstances are proposed. It is judged that newly proposed standards are appropriate in terms of both Korean national sedimental environments and economical recycling aspects because environmental standard levels proposed are higher than background level of sediments in Korea and foreign country's standards, where many experiences and environmental monitoring works have been already performed.

This study calculates carbon dioxide emissions using the fuel analysis and the continuous measurement from 500 MW-class coal-fired power plants and evaluates the characteristics of each method. The emissions calculation using fuel analysis was the lowest calculation among the emissions calculation methods. This is because of low net calorific value analysis. When using the low calorific coals, it is beneficial to utilize the fuel analysis. Also it showed the characteristics of the lower calculation emissions when used the as fired coals than the as received coals. However, the difference is negligible to less than 2%. As sample analysis personnel and equipment are limited in the present circumstances, it is also deemed appropriate to use the as received coals to fuel analysis. Continuous measurement showed somewhat higher emissions than the fuel analysis, and lower emissions than calculation method using domestic emission factors. Thus, if the calculated emission using fuel analysis increases with the coal type changes, it is beneficial to using modified flow rate measurement method.

This paper describes the beneficial effect of weldment imperfection of the cask impact limiter, by applying intermittent-weld, for impact energy absorbing behavior. From the point of view of energy absorbing efficiency of an energy absorber, it is desirable to reduce the crush load resistance and increase the deformation of the energy absorber within certain limit. This paper presents the test results of intermittent-weldment and the analysis results of cask impacts and the discussions of the improvement of impact mitigating effect by the imperfect-weldment. The rupture of imperfect weldment of an impact limiter improves the energy-absorbing efficiency by reducing the crush load amplitude without loss of total energy absorption. The beneficial effect of weldment imperfection should be considered to the cask impact limiter design.

This study utilized a standardization and cluster analysis technique for the selection and classification of beneficial bacteria. A set of synthetic data consisting of 100 individual variables with three characteristics was created for analysis. The three characteristics assigned to each independent variable were designated to have different numeric scales, averages, and standard deviations. The variables were bacterial isolates at random, and the three characteristics were fermentation products, including cell yield, antioxidant activity of culture, and enzyme production. A standardization method utilizing a standard normal distribution equation to record fermentation yields of each isolate was employed to weight their different numeric scales and deviations. Following transformation, the data set was analyzed by cluster analysis. The Manhattan method for dissimilarity matrix construction along with complete linkage technique, an agglomerative method for hierarchical cluster analysis, was employed using statistical computing program R. A total of 100 isolates were classified into groups A, B, and C. In a comparison of the characteristics of each group, all characteristics in groups A and C were higher than those of group B. Isolates displaying higher cell yield were classified as group A, whereas those isolates showing high antioxidant activity and enzyme production were assigned to group C. The results of the cluster analysis can be useful for the classification of numerous isolates and the preparation of an isolation pool using numerical or statistical tools. The present study suggests that a simple technique can be applied to screen and select beneficial microbes using the freely downloadable statistical computing program R.
