Incheon port attained two million TEU of container throughput between 2013 and 2014 as a third port in domestic container throughput. It opened a new port in Song-do, Incheon in June 2015 to prepare for the continuing increase in container throughput.Therefore, it has provided the platform for being the major container port domestically and internationally. As the role of the new port increases, the role and direction of the Incheon port liner service network attracts attention. This study analyzes the centrality of the Incheon port liner service network by using SNA (Social Network Analysis), which was introduced in the maritime economics area recently, focusing on the Incheon port liner service network. We recognize the degree centrality, closeness centrality, and betweenness centrality of each port and its effect on the Incheon port liner service network. The study showed that for Incheon port, the centrality of the Busan port in Korea, and the Hong Kong port, is high outside the country. This helps us determine that the hub of the Incheon port is neither Shanghai nor Singapore, which ranks first and second, respectively, on container throughput. It is also helps us to know that eastern China's ports have not played a role of the hub of the Incheon port until now because of the relatively low centrality of eastern China's ports.

This paper analyzes the artistic practical use of social network visualization through the aesthetic information interpretation. The first social network visualization has emerged as 'Sociogram' in the form of social network analysis(SNA). Since social network has complex, the analyzing technology of social network has emerged. Early social network visualization has a practical purpose to measure the social structure, but current social network visualization divided into various forms from artistic expressions through information. This paper divide into two categories based on the artistic application of social network visualization. First, this research focuses on the static graph based on analog. Second, this research analyze the category of interacted visualization to generate a real-time digital image. This paper presents the fusion of paradigm between engineering and art through this way.

The purpose of the study was to explore the potential of the Cluster Analysis and the Community Analysis of Social Network Analyses family in job-task analysis for curriculum design. These two multivariate analysis techniques were expected to bring us relevant and scientific information as well as inspiration in investigating the structure and nature of job system, which are critical in developing relevant curriculum. To pursue the purpose mentioned above, qualitative and quantitative data were collected from "S" Corporate, a major large high-tech manufacturing company, and analyzed by relevant analytic procedures. Results indicate that there are discrepancies between formal job structures and actual ones. Following Community analysis showed that the presence of center-marginal structure along with clustering structure in the current job formation. Interpretations of the results of the study are provided in light of past research and additional data collected from the study. Implications of the study are also discussed along with suggestions for future research.

The progress in IT has increased work efficiency in many fields, leading to the start of a new era where information is exchanged by connecting all objects under the paradigm of IoT. Interest is growing on the convergence of various fields of study that goes beyond simply applying IT to research to increase efficiency in multidisciplinary studies. As such, there is a need to develop an IT-based model that can be applied to social welfare work. Social welfare workers in Korea at present have twice the workload and stress of those of their counterparts in other OECD countries. This leads to decreased work efficiency. This paper seeks to suggest a way to increase efficiency in social welfare work by improving the work process through IT-based systems. The study is expected to contribute to increased efficiency in the area of social welfare.

Smart TV sareequipped with an operating system and combined with internet functionality. They can use various apps and contents, and provide personalized and interactive services. However, the Internet connectivity of smart TVs has several security vulnerabilities that can cause significant personal and social harm. Therefore, it is necessary to develop a smart TV with a higher level of security than is currently available. In this study, we analyze consumers' purchase intention for smart TVs with security reinforcement by applying the UTAUT2 model. The results are as follows. Firstly, it was found that performance expectancy, social influence, facilitating conditions and price value, as important variables under the existing UTAUT2 model, have significant effects on purchase intention. Secondly, effort expectancy did not have a positive impact on purchase intention. Thirdly, there was a moderating effect of gender on social influence. According to the results of this study, social influence has the most powerful effect on the purchase intention of smart TVs with security reinforcement. Therefore, in order to improve the purchase intention of smart TVs, it is necessary to expand the publicity activities designed to promote the necessity and importance of reinforcing the security of smart TVs and make them easier to use.

전자의무기록(Electronic Medical Record, EMR) 시스템은 기존에 수기로 작성하던 의무기록을 디지털화 한 것이다. 이는 다양한 장점이 있지만 의료인이 관리 도메인을 통해 환자의 정보를 세밀하게 수집할 수 있는 환자 개인의 프라이버시 침해 문제가 발생하게 된다. 즉, 관계자에 의해 의도적인 유출이 발생하거나 의료정보의 거래, 복제 등 위험성이 존재한다. 특히 일부 의료정보는 고용 차별이나 사회적 차별 등 환자에게 정신적 고통을 안겨줄 수 있다. 이러한 프라이버시 침해는 유전성 질환 유전자를 가진 사람에게 유전적 요인에 근거하는 고용 차별이 발생할 수 있다. 관련연구에서는 환자의 임상적(Clinical) 또는 유전적(Genomic) 정보가 자신의 신원과 연계되어 있다면 프라이버시 침해가 발생할 수 있음을 나타낸다. 이러한 프라이버시 문제로 인해 EMR 시스템에 기반을 둔 전자건강기록(Electronic Health Record, EHR) 시스템 또한 개인 프라이버시 침해의 위험이 존재하게 된다. 따라서 의료정보의 프라이버시 보호를 위해 부당한 고용 차별 보험 차별 사회적 차별로 연결될 수 있는 개인 의료정보의 유출방지, 타인에게 알려지고 싶지 않은 개인 의료정보가 무단으로 거래되지 않는 것을 보장해야 한다. 이를 위해 본 논문에서는 의무기록의 익명화를 통해 환자와 의무기록 간의 관계를 제거하는 여러 방법들을 소개한다.

현대 사회에서 인공지능은 다양한 분야에서 사용되며 발전하고 있다. 특히 의료, 공업, 경제, 농업, 정치 등에 영향을 미치며, 데이터 프라이버시 문제가 빈번히 발생한다. 이를 해결하기 위해 연합학습이 제안되었는데, 이는 로컬 디바이스에서 학습한 모델만을 중앙 서버로 전송하여 프라이버시를 보장하고 효율성을 높인다. 하지만 연합학습은 중앙 서버를 필요로 하므로 탈중앙적인 환경에서는 사용할 수 없는 단점이 있다. 이를 보완하기 위해 본 논문에서는 서버가 없는 다양한 환경에서 연합학습을 적용할 수 있는 비-완전 연결 분산형 연합학습 알고리즘을 소개한다. 비-완전 연결 분산형 연합학습 알고리즘은 모든 노드가 서로 연결 되어있는 상태가 아닌 특정 노드와만 연결 되어있는 형태로 대부분의 실전 분산형 환경에서 사용할 수 있다. 본 방식의 학습 정확도는 일반적인 머신러닝의 정확도와 비교하여 준수한 성능을 보여주고 있다.

현대 사회에서 전력은 사회 전체적으로 그 영향력을 미치고 있으며 그 중요성은 날이 갈수록 더하고 있다. 이러한 전력 계통의 붕괴는 사회 전체적인 마비를 일으킬 수 있으며, 그에 따른 경제적 손실은 천문학적인 액수가 될 것이다. 기존 방사상 구조의 배전계통은 붕괴에 대한 안정적이고 계획적인 계통 형성보다는 필요에 따라 연결되는 방법을 이용하였다. 하지만 독립사업부제의 시행으로 배전계통에 유발되는 혼잡과 분산전원의 투입으로 인한 역조류는 현 계통에서 불안정한 결과를 초래할 수 있으며, 이는 새로운 계통으로의 전환을 요구하고 있다. 본 논문에서는 계통의 붕괴가 있더라도 좀 더 안정적으로 중요한 시설을 보호할 수 있는 계통의 구성에 대해 연구하였으며, 이 계통의 안정도를 검증하는 것에 초점을 맞추었다.

This study examined the relationships between socio-demographic background variables, parent-child differentiation, marital stability, and psychological well-being in 382 eco-boomer married women (born in 1979-1992) whose mothers were born in 1955-1963. As a result, the higher the average monthly contact frequency with the mother, the greater the intimacy (connectivity) with the mother. The higher the number of years of marriage, the lower the marriage stability, the higher the education level, and the higher the average household income were related to the higher the self-acceptance. In addition, compared to women in single-income families, married women who receive help raising their children from their mothers did not form reliable relationships with others or show satisfaction compared to women who do not receive the assistance. Those who were well connected with their mother (or had high intimacy) had higher marriage stability, and those with higher marriage stability had higher psychological well-being. They also had better relationships with other people when married women had a higher level of parent-child differentiation.
