Most universities have been concerned about Liberal Education; whether is it on universal truth, or on training job-specialists? In consequence, the curricula have been reformed and promoted diversely. In this aspect, has been developed as convergence education. I selected two easy and short texts and tried to make the students practice and memorize the dialogues as many as possible. At the end of the class, the students presented given assignments, with theatrical performance. This study carried out the research of students' presentation and theatrical performances on the basis of group study, together with a survey of the results of questionnaires and lecture evaluation. Therefore it was a exploratory study to check out significance of variables through the correlation analysis. The students' questionnaires showed the improvement of their English ability, together with their knowledge about literature and drama, cultivating humanities through the theatrical performance. It may be said that has achieved multi-functional effects of English class converged literature, theatre and humanities even for one semester.

This paper presents the user needs analysis and information visualization for the development of a semantic-based national R&D information navigation service in information service planning phase, which converges and fuses NDSL databases and NTIS databases. To investigate and analyze the user needs for improving usability, we make an improvement plan for R&D information services via a survey targeted at 30 persons, and on-site interviews targeted at 12 persons, almost of who are researchers in industries, universities and government-funded institutes. To design new information visualization service, we propose an interactive national R&D information visualization service, which is provided in navigation type, and prescribe persona and screen prototyping according to the user needs analysis. We design the national R&D information convergence/fusion architecture based on the NDSL databases, including 345,411 academic articles, 620,555 co-authors and 49,958 reports and NTIS databases including 187,466 national R&D projects. We expect that the national R&D information convergence/fusion architecture contributes to R&D information convergence/fusion as a leading model/standard and the interactive navigation-typed information visualization service strengthens usability continuously.

In this Study, Social Network Analysis of IoT related patents in South Korea, China, and Japan was conducted from the viewpoint of patent informatics. To this end, 2,526 patents filed by PCT until December 2019 were investigated up to the subclass level of the IPC code. As a result, in the case of South Korea, representative IPC codes are in the order of G06Q, H04L, G06F, H04W, and the highest frequency of interconnection is H04L→H04W, H04W→H04L, H04W→H04B. In China, the representative IPC codes are in the order of H04L, H04W, G05B, G06Q. South Korea has strong technological convergence centered on the G06Q, while China has strong convergence centered around H04L and H04W. Moreover, in China, H04L and H04W have more diverse combinations than in South Korea in Section A, B, G, and H. In the future, it is necessary to study the diversity of technology convergence of H04L and H04W in China.

This study aims to define the basic design elements of a sonic interactive object and relate them with the different metaphor types including physical metaphor, gestural metaphor, sound metaphor, and embodied metaphor that are reflected on the interface, gesture, sound, and embodied experience. It discusses how the concept mapping can be effectively done by utilizing metaphor and considering the relationships between the types of metaphor when designing a sonic interactive object. This study has a significance in the aspect that it expanded the area of metaphor to embodied experience and subdivided the types of metaphor including visual, sound, gestural and tactile information. Furthermore, it attempted to analyze the design elements of a sonic interactive object in relation to the types of metaphor. A researcher or a designer, therefore, can use this study as a reference to design concept mapping of a sonic interactive object, in a way that the design elements and metaphor types work together effectively to enable a visitor to recognize what they are expected to do with the object more intuitively.

In modern society, which boomed it became easier to obtain the necessary information to the emergence of a variety of smart devices. Due to this, the frequency of using the content based on the Web is growing rapidly. In addition, companies are turning into a production and modify the content using the CMS under the web-based. It can be a very important part to provide users with the content. Currently web services are designing a UI to the device and provided. To improve the ease of use, they are enhancing services only by survey and analysis of the patterns of all users. Most are designed without considering the UX only in the technical aspects. In this paper, to break the limits that apply to all users of the Web service pattern analysis, we propose a visualization system via the animation based on the individual user's movement patterns and usage patterns. Through this convergence is expected to be able to transform the web from the central manager to the user UX and the planning aspects researchers.

With advances in IT Smart-Work is emerging as a new way of conducting business and several companies are considering to introduce the Smart-Work digital convergence technology. In this paper, we examined the effects of the Smart-Work IT resources on the work efficiency and the corporate performances in service industry by applying the Resource-Based View. The results of the structural equation modelling analysis showed that Smart-Work IT infrastructure and individual IT skills had positive influence on individual work efficiency while business application software and IT skills affected team work efficiency. Also, we confirmed that individual and team work efficiency positively affect financial and market performance of business firms. With the findings of the study, we expect that the introduction of Smart-Work would have positive effect, at least in service industry, on work efficiency and corporate performance, which will in turn lead to gaining competitive advantage for those firms adopting Smart-Work.

사이버위협의 증가로 사이버보안 역량을 강화할 수 있는 사이버훈련에 대한 요구가 점점 증가하고 있다. 사이버훈련이란 개인의 사이버보안 역량 강화 및 사이버공격에 대한 조직적 대응을 단련하는 일련의 행위를 가리킨다. 최근 IT 영역에서 실생활과 밀접한 관계가 있는 OT 영역으로 사이버공격 범위가 늘어나 그 피해는 증가하고 있다. 이로 인해 이들 사이버공격에 대비한 사이버훈련이 필요하며, IT 위주에서 OT를 포함한 사이버훈련으로 확장할 필요가 있다. 본고에서는 IT와 함께 OT 영역까지 사이버훈련을 수행할 수 있는 사이버훈련장 구축 연구를 소개한다. 본고에서는 OT 영역을 11개의 국가기반시설로 분류하였고, OT 사이버환경을 SW 기반으로 구축할 수 있는 방안을 제안한다. 제안된 사이버훈련장을 통해 IT와 OT 대상 사이버공격에 대한 사이버훈련을 수행할 수 있으며 사이버보안 역량을 강화할 수 있다.
