This paper aims to identify trends of domestic industry-academic cooperation through comparative analysis of domestic and overseas academic articles published over the past 10 years (2011-2021). To this end, keyword network analysis and topic modeling analysis were performed to identify the characteristics of the entire articles collected. As results, it turned out that domestic articles included school, employment, education, patent, and professor as a major keyword while for overseas articles, project, policy, innovation, and company were the main topics, and related keywords were found to be influential. These results suggest that domestic industry-academic cooperation would have been designed and led by universities focusing on education for employment, and need to be carried out more actively in the areas of 'research' and 'technology transfer with the government's related policies and support on establishing two-way relationships that can benefit both schools and participating companies.

This study aims to understand the research landscape of South Korea using the data of 2020 Google Scholar Metrics. To achieve the goal, we constructed and analyzed four types of networks including the university collaboration network, the keyword co-occurrence network, the journal citation network, and the discipline citation network. Through the analysis of the university collaboration network, we found major universities such as Seoul National University, Keimyung University, and Sungkyunkwan University that have led collaborative research. Job related keywords such as job change intention and job satisfaction have been frequently studied with other keywords. Through the analysis of the journal citation network, we found multiple journals such as The Journal of the Korea Contents Association, Korean Journal of Sociology, and Korean Journal of Culture and Social Issues that have been widely cited by the other journals and influenced them. Finally, Education, Business administration, and Social welfare were identified as the top influential disciplines that have influenced other disciplines through the knowledge diffusion. The study is the first of its kind to use the data of Google Scholar Metrics and conduct a stepwise network analysis (e.g., keyword, journal, and discipline) to broadly understand the research landscape of South Korea. Our results can be used by government agencies and universities to develop effective strategies of promoting university collaboration and interdisciplinary research.

This paper examines the implication of competition and collaboration in the innovation process for regional economic development in an increasingly knowledge-based economy. While competition is an important force in securing the competitive advantage of firms, collaboration between firms and organizations should be necessary for promoting the innovative capacity of a region. This study shows that collaboration relations based on trust and stability is important for the long-term development of learning and innovation in competitive environment, and the way how spatial proximity plays an important role in interactive learning processes. It also discusses the reason why the innovative networks facilitating the exchange of tacit knowledge should be embedded in region. Finally, the paper examines the possibility of the networks based on collaboration relationship in less-favored regions such as Chonbuk, and suggests the policy implication of the result for achieving regional innovation systems in the region successfully.

Recently, the mobile social networks, which consider both social relationship between users and mobile communication networks, have been received great attention. In this paper, we consider the trust degree of node as the social relationship for the cooperative communication networks. In contrast to the existing works that consider the case of the perfect trust degree information, for the case that transmitter has an imperfect trust degree information, we propose an imperfect trust degree based cooperative communication technique that maximizes a throughput. We first model the imperfect trust degree information as a probability distribution and derive the outage probability using the probability distribution. Then, we propose the transmission scheme that maximizes the throughput, which consider both outage probability and transmission rate. The simulation results show that the proposed cooperative transmission scheme outperforms the conventional scheme in terms of the throughput.

In this research, we conducted an empirical study on the influence of social capital on cooperative governance for the Gwangju city social economy. The results of the study are as follows. First, the social capital factor commonly affecting cooperative governance is trust. Secondly, we were able to learn that there was a difference in the results of the hierarchical regression analysis to grasp the magnitude of the relative influence of detailed elements of social capital by cooperative governance factors in order. Network(4.843) exerted the most influence in Common Decision-making, followed by Trust(3.855). Trust(3.130) exerted the most influence on Management of Governance, followed by Network(2.936). Network(2.647) exerted the most influence on Cowork System, followed by Trust(2.244). Finally, Network(4.153) exerted the most influence on Partnership Building, followed by Trust(2.244). In particular, 'Participation' was an important factor in 'Co-work System'.

In business-to-business setting, dyadic relationships between firms are of paramount interest. Recent developments in business practice strongly suggest that to understand these business relationships, greater attention must be directed to the embedded context within which dyadic business relationships take place. As a result, it is important to develop an understanding which is to move from dyadic business relationship to business networks. The purpose of the current study is (1) to identify types of network benefits: information acquisition, access to tangible resources, cooperative support from network members, (2) to model network benefit efforts on a customer orientation for customer firm, (3) to examine the relationship between network characteristics and network benefits. Adopting resource-based view and social capital theory, the conceptual model is proposed. In order to develop and test a model, this paper was empirically to examine how network characteristics can reinforce network benefits leading to focal firm's customer orientation using 123 firms. Through structural equation modeling, this research found that (1) density influences information acquisition, access to tangible resources, cooperative support from network members, (2) centrality increases information acquisition, access to tangible resources. We also find that information acquisition, access to tangible resources, cooperative support from network members enhances focal firm's customer orientation. Finally, We discuss several theoretical and practical implications, and suggest limitations for the research and future research issue.

Cooperative networks enhance the overall communication performance by combining signals from relay nodes and direct signal. In this paper, we analyze the performance of cooperative communication systems which use mixed relaying protocols. By assuming several relay nodes exist between the source node and destination node, we consider the systems use not a single relaying protocol but both decode-and-forward and amplify-and-forward protocols randomly. We analyze the effect of each relying protocol for the overall system performance, and also consider the performance depending on the relay location. Differential modulation scheme which demodulates signal without channel state information is adopted where it can be applicable fast varying channel such as railway environments.

본 연구는 친족관계의 전반적 현황과 양계화 정도를 살펴봄으로써 친족관계 영역에서 변화하는 한국가족의 현주소에 대한 정보를 제공하고자 하였다. 이를 위해 본 연구는 전국의 성인남녀 1755명을 대상으로, 본인 및 배우자 부모와의 동거여부, 거주근접성, 접촉빈도를 비교함으로써 세대관계의 구조적 차원에서 양계화가 어느 정도 이루어졌는지 살펴보았다. 또한, 양계화 정도의 구체적 내용 파악을 위하여 가족의 협력 네트워크의 양상을 조사하였다. 즉 경제적, 도구적, 정서적 지원 영역에서 도움을 주고받는 대상에 대한 조사를 통하여 가족의 지원망 구성 및 활용에 있어 친족이 차지하는 비중 및 양계성의 정도를 살펴보았다. 연구 결과, 첫째, 한국가족의 세대관계의 구조적 특성은 양계화된 모습과 부계적인 모습이 혼재되어있는 것으로 나타났다. 둘째, 가족의 협력네트워크 활용의 측면에서, 한국가족은 부계친족 및 모계친족과의 상호작용이 균형적으로 이루어지는 대칭적 양계화라기보다는 비대칭적 성격의 양계화 경향을 보였다. 이것은 부계중심적으로 규범화된 친족유대의 경향이 그대로 유지되면서 동시에 실제적 필요에 의한 아내의 친족망 활용정도가 높아진데서 기인한 결과라 할 수 있다. 이러한 결과는 한국사회의 빠른 변화에도 불구하고 가족영역에서의 변화가 상당히 느리게 진행되고 있음을 반영한다.
