The purpose of this study is to determine if natural extracts could be used as an additive in oral health food made with Weissella cibaria CMU (oraCMU). Natural extracts of green tea, mulberry leaf, licorice, and propolis, which are reported to have antimicrobial activities, were selected and used in this study. The minimum inhibitory concentrations (MIC) of extracts on periodontal pathogens such as Fusobacterium nucleatum and Porphyromonas gingivalis and their synergy effects with oraCMU by the fractional inhibitory concentrations methods were measured. From the results obtained, all the extracts showed no effect on the growth of oraCMU. Green tea extract showed the best antibacterial activity with MIC of 1.8 mg/ml against both F. nucleatum and P. gingivalis. In addition, green tea extract had a synergistic effect with oraCMU against F. nucleatum. Therefore, these results suggested that green tea extract is available as an additive in oral health food made with oraCMU.

A game story that used to be free needs a work of concrete and artificial organizing and arranging these days. This is because a game story is frequently made into a new genre such as a movie or an animation. As shown in many previous studies, most of the movies made from successful digital games failed to receive satisfying box office results. To overcome this, narratively completed storytelling should be presented from the development phase of a game. The methods are as follows: It is necessary to maximize the synergy effect through the interaction between storytelling experts, game developers, animators, and movie producers in developing a game. This will help to create a game with more sophisticated and complete narrative structure than now. It is necessary to secure the diversification of game genres. Currently in Korea, online games are unusually leading the game industry. PC games or console games are more advantageous than online games for putting a finished narrative structure into a game.

Pseudomonas aeruginosa is one of the most common pathogenic species associated with canine otitis externa (OE). Their resilience is achieved by forming a biofilm, which allows these bacteria to evade even the harshest of treatments. This study evaluated the in vitro synergistic efficacy of N-acetylcysteine (NAC) with different antimicrobial agents against P. aeruginosa isolated from dogs with OE to develop an effective treatment against P. aeruginosa. The antimicrobial activity was evaluated by the minimum inhibitory concentration test using the microdilution method. The efficacy of antibiofilm formation was evaluated using a crystal violet stain method. The treatment solutions included NAC alone, and in synergy with enrofloxacin, polymyxin B, and gentamicin. NAC alone exhibited antimicrobial and antibiofilm abilities. On the other hand, the combination of NAC and the antibiotics did not show any significant synergistic effects against P. aeruginosa.

This paper presents an experimental study exploring impact resistant properties of Kagome truss reinforced composite panels. Three types of panels with different materials and reinforcements, i.e., ultra-high-performance mortar, steel fiber, and Kagome truss, were designed and manufactured. High-velocity projectile impact tests were performed to investigate the impact response of panels with dimensions of 200 mm×200 mm×40 mm. The projectile used in the testing was a steel slug with a hemispherical front; the impact energy was 1 557 J. Test results showed that the Kagome truss reinforcement was effective at improving the impact resistance of panels in terms of failure patterns, damaged area, and mass loss. Synergy effects of a combination of Kagome truss and fiber reinforcements for the improvement of impact resistance capacity of ultra-high-performance mortar were also observed.

Wood Plastic Composite(WPC) has been introduced as a new constructional material in Europe and North America. The maintenance-free durability against weather was accepted by customers and the environment-friendly merits ignited the abrupt increase of market size. Domestic major companies have kicked off the WPC business at the market of outdoor constructional materials. Due to the high contents of natural wood fiber, the production equipments should be modified to remove the moisture, to prevent thermal degradation and to promote output rates. Materials including functional fillers play a critical role in rheological properties, which affects the physical and mechanical properties of the last products. More research might be performed for synergy effects combined by various academic fields from mechanical and chemical engineering to polymer process and material science.

This paper is to review how Korean trading companies perform and promote the digital transformation through the e-networking with global market, and how much they extend the volume of export, and make the company grow inward or outward in order to enhance the effects of economic growth in Korea. It is suggested that global agreement on e-Trade(or u-Trade) should be made in order to expand the global e-networking practices and to ensure transferring of transport documents(or business documents). Moreover, it also suggested that networking on the global trading partners such as government authorities, diplomatic offices abroad, overseas Koreans, students studying abroad, Korean merchants abroad, etc. should be made in single window for improving and upgrading the image of Korean trading companies. By making of global e-network platform between overseas business partners, trading companies are able to expect various synergy effects such as improving the satisfaction of their customers, promoting the global transactions, reducing the operation and transaction cost, helping fording overseas buyers, and extending export volume and sales profit, etc. Customers can also obtain the information about trading goods easily and rapidly, and cut down the transaction stage using information exchange with partners. All of the trading partners in the world can maintain their business partnership as long as they use the global e-network.

The purpose of this study is to examine the status and limitations of the activation plan as a result of the change in urban regeneration paradigm. In particular, the change in housing life was considered following the guidelines of the New Deal project. Specifically, the three types - General Neighborhood, Housing Support, and DongneSaligi - were analyzed from the perspective of organization, space and program. In addition, the master plan and unit project, the organization and progress, and the budget plan were reviewed. As a result, the New Deal project for urban regeneration is importance on economic regeneration, which, unlike the integrated and continuous guide proposed by the government, could limit the individual progress of transitional organizations, 2-dimensional planing and various programs. Thus, first, in order to supplement the organization's verticality and inefficiency in progress, the annual business assessment should be discouraged and the permit and progress of the project should be determined at the local government level. Second, integrated and multidimensional planning is necessary to produce synergy effects in the physical environment. Finally, the link between program unit projects and the economic effects can be considered.
