Converging technologies have become a major issue in science policy. This paper describes the current state of scientific collaboration for convergent technologies among researchers in South Korea, by conducting Social Network Analysis (SNA) with the data set of 1,095 researchers who have involved in the development of the convergent technologies. It is found that the researchers in convergent technology are more productive than the researchers in other technology domains. However, the researchers in convergent technologies have small number of collaborators, compared with their productivity. Only a few researchers have a role of the hub in the collaboration networks, meaning that the structure network is closer to than the core than the peripheral. The scientific collaboration network of the convergent technology researchers shows that the members of the network are close to each other, but there is small number of cliques.

The purpose of this research is to study possibilities of animation education in art centered STEAM. We suggest not the animation education contents model of a functional skills of the past but the one for STEAM. In order to suggest the role of animation education, we should first study the convergence values of animation. And this study make a curriculum of animation for the creativity by convergence thinking. Finally, this study build the animation class model applied in STEAM by Fogarty's integrated education method. By studying, we can get the result that animation has the convergence characteristics and it has the effective role of art centered STEAM education for the convergence thinking. Also, it is expected that the results of this study will contribute to education and training of convergence of the global talent with creativity in STEAM.

Recently, interdisciplinary studies have been receiving attention. Interdisciplinary research, especially in arts and technology, is a very interesting issue. E.A.T. was founded in New York in 1966 by artists and engineers. Based on the E.A.T. case, this study analyzed the period background in which art and technology could be converged, and the characteristics of E.A.T. works. The analysis results of the period background revealed that five factors influenced the organization and development of E.A.T.. Economic factors, artistic factors, technical factors, educational factors, and sponsored cultural factors influenced the convergence of art and technology. E.A.T. works collaborated by artists and engineers generally had three characteristics. Convergence across various fields, multi-sensitivity utilizing different senses, and interaction between the environment and humans appeared in E.A.T. works. This study provides meaningful implications for both artists and engineers who wish to overcome the limitations of artistic expression and develop new technology.

This paper presents a human-centered control algorithm for personalized autonomous driving based on the integration of inverse time-to-collision and time headway. In order to minimize the sense of difference between driver and autonomous driving, the human-centered control technology is required. Driving characteristics in case that vehicle drives with the preceding vehicle have been analyzed and reflected to the longitudinal control algorithm. The driving characteristics such as acceleration, inverse time-to-collision, time headway have been analyzed for longitudinal control. The control algorithm proposed in this study has been constructed on Matlab/Simulink environment and the performance evaluation has been conducted by using actual driving data.

Owing to its fast computing capability for fusing images, the FIHS(Fast Intensity Hue Saturation) fusion is widely used for fusion purposes. However, the FIHS fusion also distorts color in the same way such as the IHS(Intensity Hue Saturation) fusion technique. In this paper, a FIHS fusion technique(FIHS-BR) which reduces color distortion by using the ratio of each spectral band and an adaptive FIHS fusion(FIHS-SABR) using spatial information and the ratio of each spectral band are proposed. The proposed FIHS-BR fusion reduces color distortion by adding different spatial detail improvement values for each spectral band. The spatial detail improvement values are derived from the ratio of spectral band. And the proposed FIHS-SABR fusion reduces more color distortion by readjusting the spatial detail improvement values for each spectral band according to the ratio of the spectral bands. The spatial detail improvement values are derived adaptively from the characteristics of spatial information of the local image. To evaluate the performance of the proposed FIHS-BR fusion and FIHS-SABR fusion, a computer simulation is performed for IKONOS remote sensing image. Results from the experiments show that the proposed methods have less color distortion for the forest regions which reveal severe color distortion in the traditional FIHS fusion. From the evaluation results of the characteristics of spectral information for fused image, we show that the proposed methods have best results.

IT융합 적용을 위하여 컴퓨터 또는 현장 데이터 취득 유닛과 각 센서노드 간의 데이터 통신망이 필요하고 또한 중앙 제어기와 데이터 전송이 필요하다. 이러한 IT융합 데이터 통신망 구축에는 유선통신이 전송 효율측면에서 안정적이기 때문에 선호된다. 그러나 불가피하게 무선이 필요할 때 IT현장에서 주로 선택되는 무선통신망의 종류별로 특성과 장단점을 비교 분석하였다.

The purpose of this study was to analyze the characteristics of multiple-choice test items used in assessment of high school integrated science according to 2009 revised curriculum. For the analysis of the tendency of item setting, we devised an analytic framework specific to integrated science, and analyzed the characteristics of items by applying the devised framework and item response theory. The results of the tendency of item setting revealed that most of items run counter to the intent of integrated science in terms of item resource, integration extent, and cognitive level, which means teachers are stick to separative method in teaching-learning and assessment of integrated science. The results of the analysis applying item response theory showed that item difficulty was appropriate and item discrimination was considerably high. However, there was no relevance between the tendency of item setting and qualitative characteristics of the items. We also discussed some agendas to improve the teaching-learning and assessment of integrated science based on the results of this study.

Interdisciplinary, or convergence, research has been a priority for the National Research Foundation of Korea (NRF) and many scholars in Korea have proposed interdisciplinary projects. Of the 4,930 proposals for the submitted in 2017, 2,575 (52.2%) of these proposals could be considered interdisciplinary projects. However, interdisciplinary projects had an acceptance rate of 35.0%, compared to an acceptance rate of 42.1% for single-discipline proposals. According to the study, despite the large share of research projects that appear to be interdisciplinary research, the characteristics of interdisciplinary studies was not reflected properly in the evaluation. I would suggest that it is required to prepare the criteria for classification of interdisciplinary studies in the classification system of research fields so that the characteristics of interdisciplinary research projects may be duly considered.

We examined refractive error, the corrected visual acuity, phoria and fusional reserve of 114 healthy myopes and hyperopia who had no strabismus, no ocular and physical diseases. We evaluated the occurrence of asthenopia according to phoria and fusional reserve. 41 out of 114 subjects which exophoria was 69% and esophoria was 5.5%, orthophoria was 26% made a complaint against asthenopia. The subjects who had exophoria of $0-6{\Delta}$ in the range of normal state was 61.4%, while the subjects who had exophoria of $7{\Delta}$ or more in the range of abnormal state was 38.6%. Reducing fusional reserve was associated with increasing phoria. The fusional reserve twice or more than phoria were 27.2%, and twice or under were 72.8%. Futhermore, AC/A ratio for heterophoria was found from 1.0 to 12.6 and its relationship to asthenopia of phoria could not be determined.

In composite materials, the adhesion and interfacial properties were the most important factors to obtain high performance of mechanical properties. This review paper had been focused on the micromechanical evaluation methods for the interfacial property historically. The interfacial property of fiber-reinforced composites (FRC) could be evaluated using only a single fiber and matrix via various micromechanical testing methods. Self-sensing due to the fracture behavior of FRC could be determined and discussed more critically and clearly using electro-micromechanical evaluation. In this paper, the research trends for micro-mechanical evaluation of composites was summarized, and their practical applications would be suggested in the future.
