The digital contents distribution system via network provides comfortability, usability, and diversified functions to content's users. However, for the characteristic of easy access of digital contents, the copyright infringements and indiscreet contents distribution are realized in this days. In other words, any users with the authentication key can access to copyright contents with any restrictions. To solve this problems, we proposed a user authentication mechanism which prevent indiscreet access to the digital content by using user system information. Also, to provide safe distribution of digital content, we used user's unique content authentication key.

Optimizing the number of ad clicks is a large-scale learning problem that is central to the multi-billion-dollar mobile advertising industry. There are currently several optimization methods being used, including ad mediation and ad positioning. Recently, researchers have recommended using ad refresh interval as a new method for optimizing mobile advertising. This paper applies that new method to optimize content duration for mobile ads. The result achieved from this optimization study could further increase revenue for mobile advertisers and publishers. This research has high applicability for the growing mobile advertising industry. It also lays out a solid background for future research in this promising area.

Linerboards containing wood flours were developed to increase solid contents in wet pressing process. Presence of wood flours in recycled fibers allowed passage of pressurized water at high wet pressing pressure, and increased solid contents while keeping the bulk of the board. The amount of wood flour addition should be controlled based on the intensity of the wet pressing pressure and the properties of the wood flours. Addition of cationic starch to the wood flour containing OCC furnish showed synergic increase of solid content and strength properties. Shapes of the wood flours such as spherical and rod type added to OCC furnish affected largely their solid content, drainage, and board physical properties.

Using the high-pressure heating extraction process suitable for mass-production, crab stock(CS), red crab stock(RCS) and fish stock(FS) were manufactured and their quality and organic features were compared. The results are as follows. In mineral content, the content of essential amino acids, the content of delicious amino acids and preference, CS and RCS were rated higher than FS, and especially RCS had the most abundant essential amino acid content and had the highest rating in organic evaluation. Also, in terms of cost, RCS was more economical than regular CS, which is relatively expensive. Therefore, it is believed that replacing fish bones with RCS in making stock will be more cost-saving and have higher preference.

The present study has been performed to select the osmotic tolerant lines using polyethylene glycol (PEG 6000) through an in vitro and in vivo mutagensis with a gamma-ray. During the screening, we selected three mutant lines that seemed to confer elevated osmotic tolerance in high concentrations of PEG 6000. Fruits of these mutants (Os-HK101, Os-HK102 and Os-HK103) were increased to sugar concentration, L-glutamine acid, vitamin C content and lycopine content than those of the wild type. Also the chlorophyll contents were few decreased more in the three mutant lines than the WT plants. Our results suggest that the Os-HK101 is characterized as osmotic stress tolerance considering the sugar concentration and lycopine content. It is expected that the result of this study can be used for breeding more competitive species with respect to contents in sugar or functional chemicals from the selected osmotic resistant lines.

팽이버섯 포장필름의 국산화 및 동남아시아 지역을 대상으로 한 수출용 필름을 개발하기 위하여, 개발된 포장필름을 현재 시중에 유통 중인 포장필름 및 수입산 포장필름과 함께 저장 중 팽이버섯의 저장 온도별 품질변화에 이어 유리당, 유리아미노산, 구성아미노산 등에 대한 영양학적 특성변화를 검토하였다. 유리당 함량을 분석한 결과, 저장 온도가 높아질수록 유리당 함량이 약간씩 증가하는 경향을 보였으나, 포장 필름의 종류에 따라서는 큰 차이를 나타내지 않았다. 유리아미노산의 경우 저장온도가 올라감에 따라 methionine은 증가하는 반면, tyrosine은 감소하였다. Polyphenol oxidase의 활성 확인결과 본 과제로 인해 개발된 포장지가 우수함을 확인하였다. 베타글루칸 함량은 건강 기능성 식품의 표준 지표로 사용되는 성분이나 버섯 저장성을 판단하는 지표로 사용하기에는 적당하지 않을 것으로 여겨진다.

In our study, lactic acid bacteria (LAB)-fermented whey solutions were applied in the soybean soaking process to minimize bacterial contamination and to enrich the biologically functional components of isoflavone and $\gamma$-aminobutyric acid (GABA). Among the 11 LAB tested, Bifidobacteria infantis and a mixed culture (Lactobacillus acidophilus, Bifidobacteria lactis, and Streptococcus thermophilus; ABT-3) displaying the greatest $\beta$-glucosidase activity were selected to produce improved biologically functional soybean preparations. In the soybean soaking processing (without water spraying), the LAB-cultured 10% whey solution was used to soak and to ferment the soybeans and the fermented soybeans were finally dried by heat-blowing at $55^{\circ}C$. The processing conditions used in this study demonstrated that the final soybean product had a reduced contamination by aerobic and coliform bacteria, compared to raw soybeans, likely due to the decrease in pH during LAB fermentation. The aglycone content of the isoflavone increased up to 44.6 mg per 100 g of dried soybean by the processing method, or approximately 8-9 times as much as their initial content. The GABA contents in the processed samples increased as the processing time of soaking-fermentation proceeded as well. The soybean sample that fermented by ABT-3 culture for 24 hr showed the greatest increase in GABA content (23.95 to 97.79 mg/100 g), probably as a result of the activity of glutamate decarboxylases (GAD) released from the soybean or produced by LAB during the soaking process.

2012년에 한미 FTA가 발효되었으며 콘텐츠산업분야에서 역대 FTA 중 가장 많은 부분에서 시장개방이 이루어졌다고 평가받고 있다. 본 연구는 한미 FTA 체결에 따른 콘텐츠산업분야의 시장개방 효과의 하나로 수출입 효과를 실증적으로 분석하였다. 이는 정책적으로는 한류로 대표되는 한국 콘텐츠산업의 대외경쟁력이 FTA와 어느 정도 연관성이 있는 것인지에 대한 의미있는 해석을 도출한다. 이를 위해 1차적으로는 ANOVA 분석을 통해 평균적인 FTA 효과 유무를 추정하고, 이후 다른 요인들이 통제된 후 직접적인 FTA 효과 추정을 위해 회귀분석을 실시하였다. 한미 FTA로 인해 미국산 콘텐츠가 국내 시장을 잠식할 것이라는 우려와는 달리, 콘텐츠 수입측면에서는 통계적으로 유의한 변화가 발생하지 않았다. 콘텐츠 수출은 한 미 FTA협정 발효 후에 오히려 증가하여 대미 수출액에 통계적 유의미한 변화가 있었지만 한 미 FTA체결에 따른 효과가 아니라 그 외적인 변수들로 인해 수출액이 증가했다는 해석이 회귀분석을 통해 알 수 있었다. 실제 한 미 FTA협정의 콘텐츠산업 분야에서의 시장개방의 하나인 외국제작물의 편성비율 조정이 별다른 의미를 갖지 못했고 국내 제작물의 편성비율이 오히려 증가한 것을 보면 국내 콘텐츠의 전체적인 시장경쟁력이 높아졌고, 그 결과로 대미 수출이 증가한 것으로 볼 수 있다.

This paper examines export promotion plans of digital content industries, particularly of game, animation & character industry based on the OSMU(One-source Multi-Use) strategy. As the digital content industry is one of the newest industries as a source of strategic export, we must promote the export of digital contents that hold so much international competitiveness and through that promotion, we have to strengthen the international competitive power. The game, animation & character contents are very easy to adapt each other for creating new contents by omnidirectional OSMU. Therefore, it is intended to present some primary factor for export promotion of game, animation & character contents through the OSMU strategy.

In this paper, we propose a user matching app based on hybrid app and a utilization plan to promote sports tourism in line with the growing trend of sports industry scale. The proposed app categorizes sports facilities across the country into regional, sports, private and public sports facilities to support reservations and matching. The proposed app applied a matching system in which matching scores were given according to the preference of events, places, and users by user net matching algorithm. Users can enjoy sports as a team or individual through the suggestion app even if they do not have any clubs or friends to which they belong. It can be used to improve tourism content services and establish tourism industry policies by analyzing data generated while using a user matching system.
