The objective of this study is to investigate the commercializations and difficulties on the farm-food. For the activation of the farm-food, it is necessary to totally review the support of the government and prepare the supporting system like manual on the commercialization of farm-food that is helpful to the small farmers. It is also necessary to support small farms strategies customized for increase the sales and satisfaction on farm-food and build-up the promotion related to the green tour and/or farm experience. The results and finding of this study can be used to build-up the supporting system that reflects the rapid change of market and customer's preference. They can also be used to design rational policies that is helpful to the farm-food producers.

경제가 발전함에 따라서 개인적인 외모에 대한 관심이 고조되어지고 있다. 그 가운데 개인별 헤어스타일 및 헤어관련 관심이 증가하고 있는 상황이다. 특히, 여성의 영역으로 이해되어지던 헤어부분도 남성들의 관심이 증가함에 따라 이들에 대한 상품화 마케팅 전략이 필요하게 되었다. 이에 본 연구에서는 개인별 맞춤형 헤어제품의 마케팅 강화를 위한 현황을 분석해보며, 특히 온라인을 통한 마케팅 전략 강화를 위한 방안을 제안한다. 또한 이를 실현하기 위한 온라인 헤어제품 상품화 마케팅 구현결과를 제시함으로써 온라인을 통한 마케팅 전략 서비스 개발에 관하여 살펴보고자 한다. 이를 통해 온라인을 통한 헤어제품의 마케팅 활성화에 이바지 할 것으로 기대된다.

The Purpose of this study is to exmaine fundamental problems of Gwangyang Port and draw up plans of its Hub Port. Gwangyang Port has been gradually reduced container cargo increase rate. on account of large development of Chinese Port, undevelopment of Hinterland, Port facilities of Gwangyang Port. We should develop hinterland to be closely connected with Port Cluster, Business City, Free Economic Zone to increase cargo volume. and in order to increase transshipment cargo volume, We should prepare diverse plans that can induce Chinese and Japanese transshipment cargo. Gwangyang Port and Busan Port should be managed united one port system by a Port Authority to strengthen international competitiveness. Activation of new ports for the most part call for full support by Government at the beginning. Gwangyang Port's future it can be if Government has strong will.

It is hardly achieved Electronic Commerce (EC) activation if there isn't any performance in spite of the estimation that EC would improve whole economic efficiency. Therefore, there should be a need for the research whether implementation and utilization of EC really improve companies' business performance. The primary purpose of this study is to investigate the level of EC utilization in Small and medium sized enterprises (SMEs) and analyze its effect on business performance in terms of BSC. The results indicate that EC utilization in various fields of business and the use of information created through EC are significantly related to higher business performance, but EC volume is not. This study examines facing problems of SMEs in utilizing EC as well.

On cold start operation of an SI engine, a catalyst shows poor performance before it reaches activation temperature. Therefore, fast warmup of the catalyst is very crucial to reduce harmful emissions. In this study, an appropriate control strategy is investigated to increase exhaust gas temperature through changes of spark timing. Combustion stability is also considered at the same time. Exhaust gas temperature and pressure of combustion chamber are measured to investigate the effects of spark timings on cold start and idle performance. Experiments showed that retarded spark timing promotes the combustion at the end of expansion stroke and increases exhaust gas temperature during cold start.

In this paper, we propose a new model for predicting effective Win/Loss in professional baseball game in Korea using machine learning technique. we used basic baseball data and Sabermetrics data, which are highly correlated with score to predict and we used the deep learning technique to learn based on supervised learning. The Drop-Out algorithm and the ReLu activation function In the trained neural network, the expected odds was calculated using the predictions of the team's expected scores and expected loss. The team with the higher expected rate of victory was predicted as the winning team. In order to verify the effectiveness of the proposed model, we compared the actual percentage of win, pythagorean expectation, and win percentage of the proposed model.

Microglia are emerging as critical regulators of innate immune responses in AD and other neurodegenerative disorders, highlighting the importance of understanding their molecular and cellular mechanisms. We attempted to determine the role of crosstalk signaling between $IFN-{\gamma}$ and $TGF-{\beta}$ in $A{\beta}$ clearance by microglia cells. We used in vitro and in vivo mouse models that recapitulated acute and chronic aspects of microglial responses to $A{\beta}$ peptides. We showed that crosstalk signaling between $TGF-{\beta}$ and Smad2 was an important mediator of neuro-inflammation. These findings suggest that microglial $TGF-{\beta}$ activity enhances the pathological progression to AD. As $TGF-{\beta}$ displays broad regulatory effects on beneficial microglial functions, the activation of inflammatory crosstalk signaling between $TGF-{\beta}$ and Smad2 may be a promising strategy to restore microglial functions, halt the progression of $A{\beta}$-driven pathology, and prevent AD development.
