The concept of RIS(Regional Innovation System) has widely been used in discourse and policy issues in Korea. But most studies of RIS concern on BT or IT industries combining with diverse regional agencies in urban areas. Some other studies were concentrated on general ideas or concept of the RIS. The purposes of this study are (1) to suggest a analytical method to select specialized industry in local autonomy, (2) to analyze the relationship between specialized industry and gross sales of agricultural products and stock farm products, (3) to analyze the relationship between gross sales of agricultural products and stock farm products and GRDP, and (4) to construct a model of RIS that fits particularly for rural areas. This study particularly accentuates that a specialized industry is more meaningful when it can raise GRDP, which eventually can give positive effect of RIS on regions.

Present study evaluated the low-temperature destruction of n-hexane and benzene using mesh-type transition-metal platinum(Pt)/stainless steel(SS) catalyst. The parameters tested for the evaluation of catalytic destruction efficiencies of the two volatile organic compounds(VOC) included input concentration, reaction time, reaction temperature, and surface area of catalyst. It was found that the input concentration affected the destruction efficiencies of n-hexane and benzene, but that this input-concentration effect depended upon VOC type. The destruction efficiencies increased as the reaction time increased, but they were similar between two reaction times for benzene(50 and 60 sec), thereby suggesting that high temperatures are not always proper for thermal destruction of VOCs, when considering the destruction efficiency and operation costs of thermal catalytic system together. Similar to the effects of the input concentration on destruction efficiency of VOCs, the reaction temperature influenced the destruction efficiencies of n-hexane and benzene, but this temperature effect depended upon VOC type. As expected, the destruction efficiencies of n-hexane increased as the surface area of catalyst, but for benzene, the increase rate was not significant, thereby suggesting that similar to the effects of the reaction temperature on destruction efficiency of VOCs, high catalyst surface areas are not always proper for economical thermal destruction of VOCs. Depending upon the inlet concentrations and reaction temperatures, almost 100% of both n-hexane and benzene could be destructed. The current results also suggested that when applying the mesh type transition Metal Pt/SS catalyst for the better catalytic pyrolysis of VOC, VOC type should be considered, along with reaction temperature, surface area of catalyst, reaction time and input concentration.

본 논문은 디지털 기술의 발전에 따른 문화콘텐츠 유통의 발전, 특히 게임산업의 유통체계를 살펴보고 있다. 컨버젼스 기술의 발전에 따라, 문화콘텐츠 유통에 있어서 핵심적인 가치의 중심은 플랫폼에서 콘텐츠로 옮겨가고 있는데, 이와 관련하여 특히 게임산업의 유통구조에서는 3가지 유형(오프라인, 온라인, 모바일 게임)이 나타난다고 알려지고 있다. 본 논문에서는 심층인터뷰 등을 통한 사례조사를 통해 앞으로 통합적인 모델로 발전할 것으로 검증하고 있다. 결론적으로 본 논문은 이러한 변화에 맞추어 앞으로 문화콘텐츠산업의 장기적인 발전을 위해 유통구조의 개선, 기업과 퍼블리셔 등 관계자들의 갈등해소, 국제화 등을 위한 다각적 정책지원이 더욱 필요함을 제안하고 있다.

The purpose of this paper investigates the operational efficiency of nationwide flower chain based on survey data in Korea. Three problems in the operational efficiencyappear: first, the main office does not match the amount of order with that of delivery, and there are competitors of the same chain in the same district second, the quality of flower delivered is not standardized third, the main office and the chain store in the nationwide flower chain does not achieve the incentive compatibility in making and sharing the joint profit. Hence the key point to succeed in the small flower shop is to create its own customers in the district and the nationwide chain only provides the complementary market to local flower store.
