Wind energy began to receive attention as a new alternative fuel since 20 years ago and is growing as a booming global business model. Global wind power generation in the world has been continuously increasing for the past 10 years, accounting for over 30% of cumulative rate compared to total power generation. Global demand for wind power generation is gradually expanding due to restriction on carbon emission and environmental problems caused by increased greenhouse effect. Accordingly in this study, current transportation routes are classified into three types including access-priority route, economics-priority route, and convenience- priority route depending on distribution characteristics of wind power equipment in order to suggest transportation methods other than ships. The three types of transportation route that this study declared can make the Wind power equipment manufacturing companies can judge not only the duration of transportation but also effectiveness and economic feasibility. It means that the manufacturers can analyze and compare the effectiveness and economic feasibility, which are proceed by the shipping company and freight forwarder until now days.

In the process of industrial restructuring at the regional and firm's level induced by significant changes in external economic circumstances, geographic and economic inheritances could be exploited as a constraint and/or asset for firms' strategies. Through a theoretical discussion of this argument, an attempt has been to categorize the effects of inherited regional assets on firms' strategies and regional development and to analyze the firms' strategies located at the city of Ansan. Capitalizing upon this empirical findings, some feasible development paths of Ansan in the future have been proposed and then critically discussed.

In this study, text mining and main path analysis (MPA) were applied to understand the origins and development paths of research areas that make up the mainstream of Korean studies. To this end, a quantitative analysis was attempted based on digital texts rather than the traditional humanities research methodology, and the main paths of Korean studies were extracted by collecting documents related to Korean studies including citation information using a citation database, and establishing a direct citation network. As a result of the main path analysis, two main path clusters (Korean ancient agricultural culture (history, culture, archeology) and Korean acquisition of English (linguistics)) were found in the key-route search for the Humanities field of Korean studies. In the field of Korean Studies Humanities and Social Sciences, four main path clusters were discovered: (1) Korea regional/spatial development, (2) Korean economic development (Economic aid/Soft power), (3) Korean industry (Political economics), and (4) population of Korea (Sex selection) & North Korean economy (Poverty, South-South cooperation).

The purpose of this study is to investigate the characteristics of the elderly based on the types of Kyungrodang participation and explores ways toward development of Kyungrodang. A national sample data, collected by the Korean Institute for the Health and Social Welfare in 2004 is analyzed by employing Chi-Square test of independence, ANOVA, and multiple logistic regression(n=3,005). A significant difference is noted in age, area, and socioeconomic status among the elderly based on the types of Kyungrodang participation. The results show that those elderly living in rural areas with older and lower socioeconomic status are more likely to participate at Kyungrodang, whereas, elderly living in urban areas with younger and higher socioeconomic status are less likely to participate at Kyungrodang and discontinue to use the services. Although there is a difference between the gender, the most significant reason for not using and discontinuing Kyungrodang is because the elderly can not get along with the other participants. In other words, the major problem that needs to be solved is to socializing and providing service programs satisfying all participants. Based on the results and recent socioeconomic changes of the older population, some policy issues are suggested for the development of Kyungrodang.

This study investigates the development path and intellectual structure of data literacy research, aiming to identify emerging topics in the field. A comprehensive search for data literacy-related articles on the Web of Science reveals that the field is primarily concentrated in Education & Educational Research and Information Science & Library Science, accounting for nearly 60% of the total. Citation network analysis, employing the PageRank algorithm, identifies key papers with high citation impact across various topics. To accurately trace the development path of data literacy research, an enhanced PageRank main path algorithm is developed, which overcomes the limitations of existing methods confined to the Education & Educational Research field. Keyword bibliographic coupling analysis is employed to unravel the intellectual structure of data literacy research. Utilizing the PNNC algorithm, the detailed structure and clusters of the derived keyword bibliographic coupling network are revealed, including two large clusters, one with two smaller clusters and the other with five smaller clusters. The growth index and mean publishing year of each keyword and cluster are measured to pinpoint emerging topics. The analysis highlights the emergence of critical data literacy for social justice in higher education amidst the ongoing pandemic and the rise of AI chatbots. The enhanced PageRank main path algorithm, developed in this study, demonstrates its effectiveness in identifying parallel research streams developing across different fields.

정보화 사회로 발전하고 네트워크가 큰 폭으로 발전함에 따라 사회에 대한 네트워크의 의존도가 커져 가고 있다. 그러나 네트워크가 발전할수록 미래의 다양한 사용자 요구사항 및 새로운 네트워크의 한계성이 나타나고 있다. 이러한 문제를 해결하기 위한 방안 중 하나로 OpenFlow기법이 제안되었다. 본 논문에서는 이러한 OpenFlow기반의 네트워크를 관리하기 위해 VN Manager(Virtual Network Manager)와 이를 활용한 경로 관리 프로그램을 구현하였다. 또한 경로 생성시 QoS를 보장하기 위해 Admission Control이 가능하도록 하였다.

This study examines the development direction of Ulsan automobile cluster and suggests strategic interventions, based on the possibility of system transformation in the open economic system. The spatial characteristics of global, national and local production and R&D networks were analyzed to investigate the conditions of Ulsan automobile cluster. And the agglomeration process of automobile industry and the capabilities accumulated in Ulsan were analyzed and alternative developmental path and policy suggestions were proposed.

통신망의 발전으로 사용자는 새로운 인터넷 서비스를 요구하게 되었다. 이러한 서비스의 대부분은 멀티 캐스팅을 사용하며, 전송되는 데이터는 대용량의 멀티미디어 데이터가 주를 이루고 있다. 멀티미디어 서비스는 일정한 수준의 서비스를 위하여 신뢰도를 보장해야만 한다. 신뢰도는 경로의 흡수와 관련되어 있다. 즉, 경로에 포함된 홉의 수가 많아지면 그 경로를 통한 서비스의 신뢰도는 떨어지게 된다. 이러한 이유로 전송에 관련된 경로의 홉수에 제한을 두는 것은 통신의 신뢰성을 위하여 고려되어져야하는 중요한 문제이다. 본 논문에서는 멀티캐스트 트리의 각 경로의 흡수와 비용의 관계를 알아보기 위해 유전자 알고리즘과 개미 알고리즘을 사용한다.

Today, the location based service(LBS) is globally developing with the advance of smart phones and IOT devices. The main purpose of this research is to provide users with the most efficient route information, analyzing big data of people with a variety of routes. This system will enable users to have a similar feeling of getting a direct guidance from a person who has often used the route. It is possible because the system server analyzes the route information of people in real time, after composing the distributed processing system on the basis of map information. In the future, the system will be able to amazingly develop with the association of various LBS services, providing users with more precise and safer route information.
