The purposes of this research are to examine the theoretical background and industrial policy issues with regard to building a Innovation System for encouraging industrial competitiveness and fostering regional industry in Korea. Knowledge has become the driving force of economic growth and the primary source of competitiveness in the world market. So since 1990s, Innovation Systems have been put emphasis on as new industrial development strategy in a knowledge-based economy. It can be understood that Innovation System is composed of National Innovation System(NIS) and Regional Innovation System(RIS) and interrelated the concept of clusters and networks, which are contribute to industry development throughout boosting innovation. As for the Korean industrial policy, when the former centralized policy decision making process became decentralized through the implementation of local autonomy, the role of local or state government in relation to regional industrial promotion intensified. But with the impotance of for fostering strategic industry in the region. new industrial policy issues in Korea are needed as follows; $\circled1$ Building a market-oriented support system for industrial cluster through providing the resource of innovation. $\circled2$ Establishing agency for regional industrial development. $\circled3$ Making a evolutionary vision for broader region including 2 or 3 province, $\circled4$ Fostering strategic industry which is selected in term of specialization and potential of the region. The RIS model for industry development is outlined in this paper but policy initiatives for building a RIS have to be extracted from further case studies.

소비자의 욕구변화와 정보기술의 발전으로 정보경제시대, 신경제시대가 도래함에 따라 가치사슬이 변화하고, 새로운 가치를 창출하는 신산업이 등장하고 있다. 인터넷의 확산과 더불어 선으로부터의 자유, 개인성, 즉시성이 가능한 모바일 비즈니스가 우리나라에서도 태동하고 있다. 모바일 비즈니스는 금융업체, 정보제공업체, 통신망 운용업체, 최종이용자간의 새로운 가치의 결합이 특징이며, 막 흐름이 만들어지고 발전되고 있는 상황이다. 이와 같이 다양한 이해관계자가개입하고 있어 협력이 특히 강조되고 또 요구되고 있다. 이러한 중요성에도 불구하고 이들간의 관계에 대한 연구가 미흡한 편이다. 따라서 본 연구는 모바일 비즈니스를 주도하고 있는 통신망 제공업체와 모바일 컨텐츠 공급 파트너간의 조직간 협력관계에 대한 실증 연구를 수행하였다. 관계마케팅, 거래비용, 자원기반관점, 네트워크 이론 등 기업간 관계를 기술, 설명, 예측하는 주요이론에서 논의되고 있는 개념을 바탕으로 본 연구는 컨텐츠 공급파트너의 전략적 성과에 영향을 주는 연구 모형을 제시한다. 최근 중요성이 더 강조되고 있는 항목은 신뢰와 결속임을 감안하여, 매개변수로써 전략적 성과에 영향을 주는 주요한 요소로 신뢰와 결속을 제시하고 있다. 컨텐츠 제공업체의 전략적 성과는 서비스제공업체에 대한 신뢰와 결속에 큰 영향을 받고있다는 점을 반영하고 있다. 한편 신뢰에 영향을 주는 독립변수로는 서비스 제공업체에 대한 평판, 서비스제공업체와 컨텐츠 제공 파트너간의 상호의사소통, 그리고 업무처리의 절차에 대한 공정성을 제시하고 있다 결속에 영향을 미치는 독립변수로는 동의된 목표, 업무정보교류, 거래특유자산의 3개의 변수를 선정하였다. 독립, 매개, 종속변수간의 9개의 연구 가설을 수립하였다. 국내의 주도적인 이동통신망소유업체에 모바일 컨텐츠를 공급하고 있는 170여개의 파트너를 대상으로 실증연구를 수행했다. 공변량 구조분석을 위주로 분석한 연구의 결과에 의하면 본 연구의 모델은 충분한 적합성을 보여주고 있는 것으로 나타났다. 또한 가설의 상당수가 채택이 되었다. 그러나 모바일 비즈니스의 기업간관계의 실제측면을 나타내는 업무정보교류와 결속자의 관계의 유의하지 않게 나와 기각되었다. 기각에 대한 여러 가지의 해석이 가능하지만 측정의 신뢰성을 확보해야 하고 개념의 타당성을 더 엄격하게 준수할 필요성이 제기되었다. 본 연구는 조직이론에 근거한 변수를 채택하고 있으나 모바일 비즈니스의 생명주기특성상 태동기이기 때문에 기업간 관계를 연구하는 측면에서는 탐험적 연구성격이 강하다. 더 나아가 본 산업의 주된 연구가 질적이고 기업내부만을 연구했던 것에 비교하면 시초적이라고 할 수 있다. 또한 관계마케팅, CRM 등의 이론적 배경이 되고 있는 신뢰와 결속의 중요성이 재확인하는 결과도 의의라고 할 수 있다. 그리고 신뢰는 양사 간의 상호관계에서 조성될 수 있는 특성을 가진 반면, 결속은 계약관계 초기단계에서 성문화하고 규정화 할 수 있는 변수의 성격이 강하다고 할 수가 있다. 본 연구는 복잡한 기업간 관계를 지나치게 협력적 측면에서만 규명했기 때문에 많은 측면을 간과할 가능성이 있다. 또한 방법론적으로 일방향의 시각만을 고려했고, 횡단적 조사를 통하고 국내의 한 서비스제공업체와 관련이 있는 컨텐츠 공급파트너만의 시각을 검증했기 때문에 해석에서 유의할 필요가 있다. 또한 타당성확보 노력을 기하였지만 측정도구 면에서 엄격한 개발과정을 준수하지는 못했다. 향후에는 모바일 컨텐츠 파트너의 기업의 특성을 조사하여 관계성 변수와의 상호관련연구를 진행할 필요가 있다. 관계기간, 의존성, 거래처의 단/복수여부, 서비스 범주 등의 제반 변수를 고려하여 이러한 변수가 양사와의 관계성 변수에 어떤 영향이 있는가를 검증할 필요가 있다. 또한 신뢰, 결속 등 다차원의 개념에 대한 심도 깊은 연구와 최근 제기되고 있는 이론의 확대도 필요하다. 마지막으로 신뢰와 결속에 영향을 미치는 요소간의 개념적 분류, 차이의 검증, 영향력 등을 광범위하게 진행시킬 필요가 있다.

딥러닝 기술은 더 많은 분야와 과제에 적용되기 위해서 네트워크는 더 복잡하고 거대한 형태로 발전해왔다. YOLOv7-tiny과 같은 객체탐지 네트워크는 다양한 객체와 환경에서 활용하기 위해 COCO 데이터 세트를 대상으로 발전해왔다. 그러나 본 논문에서 적용할 모델은 임베디드 보드 환경에서 실시간으로 1개의 Class를 대상으로 객체를 탐지하는 네트워크 모델이 찾고자 프루닝을 적용하였다. 모델의 프루닝을 할 필터를 찾기 위해 본 논문에서는 클러스터링을 통한 필터 프루닝 방법을 제안한다. 본 논문의 제안 방법을 적용했을 때 기준 모델보다 정확도가 7.6% 감소하였으나, 파라미터가 1% 미만으로 남고, 속도는 2.1배 증가함을 확인하였다.

Enterprises' participation in the collaboration research is one of the effective and typical methods through which technologies go into the market or are transferred to other sectors. This study reviews enterprises' participated collaboration research and analyzes their network for disaster and safety management area. From 2005 to 2016, 786 technical papers from four representative journals for disaster and safety management in Korea are compiled based on the authors whose affiliations are from enterprises. During the research period, collaboration research is found to be in an increasing trend in general. However, the number of technical papers with three or less authors is in a decreasing trend, whereas that with four or more authors is in an increasing trend. This fact implies that the range of enterprises' collaboration research is widening. Technical paper productivity and each entity's collaboration network are evaluated using participation-weight based author score. Over the research period, a few universities, which attract most of the enterprises, are found to have higher productivities and centralities. Public enterprises show higher participation weights. Also, sectors such as construction, engineering, and electronics demonstrate higher weights. This study is particularly meaningful because enterprises' participation status in collaboration research for disaster and safety management area is systematically analyzed for the first time in Korea. The network analysis result from this study will be especially helpful in establishing technology transfer strategy.

The Korean innovation ecosystem has evolved from a catch up stage to a creative leader stage where government's role in creating a private sector driven, healthy and dynamic ecosystem is important. Korea's innovation ecosystem shows a stagnation of innovation performance and a lack of linkage activities within the national innovation ecosystem and in global cooperation, despite the dramatic advancement and expansion of the ecosystem. A next-generation innovation ecosystem model is required to create a future-oriented innovation ecosystem. The next generation innovation ecosystem was prepared on the basis of the framework, which has 6 elements among which inter-firm network is the the micro-foundation of the ecosystem. On the basis of the framework, assuming that the next generation innovation ecosystem is the evolved existing ecosystem, responsive the discontinuous change in market and technology, which is private sector driven healthy and dynamic ecosystem, the next generation innovation ecosystem model was created. The concrete details on the direction of the policy entities responsible for building the ecosystem was presented, and the contribution of this study was discussed.

This research aims to empirically investigate into the relationship between venture entrepreneurs' social network and their social competence to utilize the network, which is known to help overcome the weaknesses of small-and-medium-sized ventures. An analysis was made of SEM set up with 211 entrepreneurs' responses, and the following are the findings from the analysis. First, venture entrepreneurs' networking ability has a significant, strong and positive effect on weak tie of their social network(${\beta}$=.527, C.R.=3.626), strong tie(${\beta}$=.594, C.R.=3.969), and the network centrality(${\beta}$=.418, C.R.=4.884). Second, their social astuteness also has a significant and positive effect on weak tie(${\beta}$=.192, C.R.=1.701), strong tie(${\beta}$=.269, C.R.=2.509) and the network centrality(${\beta}$=.228, p=2.283). Third, their interpersonal influence has a significant but negative effect only on strong tie(${\beta}$=-.264, C.R.=-1.862) and the network centrality(${\beta}$=-.394, C.R.=-2.914). Lastly, their apparent sincerity has no significant effect on the subordinate factors of social network. This research has not just empirically analyzed the relationship between the entrepreneurs' social network and their social competence. But also, results of the research provide practical and detailed information to entrepreneurs of small and medium ventures. Moreover, the research is significant in that it has suggested and empirically analyzed the concept of political competence, which is a concrete substance of social competence, and that it has offered theoretical foundations for future researches, which will tackle the issue of the entrepreneurs' competence in the sphere of entrepreneurship.

Much Interest has focused on social network services such as Facebook and Twitter. Previous research conducted on social network often emphasized the architecture of the social network that is the existence of path between any objects on network and the centrality of the object in the network. However, studies on the semantic association in the network are rare. Studies on searching semantic associations between entities are necessary for future business enhancements. In this research, the ontology based social network analysis is performed. A new method to search and rank relation sequences that consist of several relations between entities is proposed. In addition, several heuristics to measure the strength of the relation sequences are proposed. To evaluate the proposed method, an experiment was performed. A group of social relationships among the university and organizations are constructed. Some social connections are searched using the proposed ranking method. The proposed method is expected to be used to search the association among entities in ontology based knowledge base.

In this paper, we analyze features of radical innovative businesses using their patents. Although patents have been used to evaluate outcomes of businesses from the 1980s, it is challenging to use patents for radical innovations. We examined the possibility of taking advantage of patents for an indicator that represents a radical innovation in pharmaceutical industry. To this end, we collected FDA approval data from the U.S. Food and Drug Administration and patent data of 18 pharmaceutical companies. For analysis, we utilized the network centrality analysis and Wilcoxon signed ranked test, which is a non-parametric statistical hypothesis test used to compare two related samples. We observed that a radical innovative company typically cooperates with other research groups, such as universities and companies, and acts as a hub for connectivity in pharmaceuticals. Also, we found that there are differences in centrality between radical firms and non-radical firms. Thus, we expect that the results of this study will help in developing strategies for research and development of pharmaceutical companies and identifying factors affecting radical innovation in the future.
