By the means of pervasiveness of ICT, ICT firms in the dynamic competition try to get the competitive advantage through the combination with the other industrial technologies and the firms in other industries also seek innovations in this way. To ICT suppliers, the application industries were completely different before but if ICT is applied to that industries once, the convergence phenomenon could occur as a part of an ICT industry. So, this research focuses the causality between ICT supplier's behavior and technological convergence according to the research question about what should ICT firms do for ICT convergence. We observed technological changes in the automotive industry through the Nasdaq listed firms' patent activities of 10-year period from the perspective of evolutionary theory. As a result, while the innovativeness of technological trials by ICT suppliers enhances the possibility of technological convergence, diversity of those can reduce the emergence of ICT convergence. This implies that ICT firms should focus specialized technologies for convergence rather than various technological options for the uncertain future.

In this paper, we show how dynamic manipulation environments can be integrated in the mathematics curriculum by presenting some pedagogical tasks manufactured by dynamic manipulation. These examples are composed to produce meaningful definitions through inductive experiments, to strengthen the thinking ability on continuity through the visualization, to make mathematics through investigation and finding, and to strengthen the ability of posing and generalizing problems. Through these examples students can observe the process of how mathematics is being invented, and they can experience how to solve mathematical problems using physical experiments in dynamic manipulation environments. When integration of dynamic manipulation into the teaching and learning of mathematics is applied, some difficulties can come out. To resolve such difficulties, a teacher must play the role of a co-worker of students in addition to the role of a scaffolder, coach, or close listener.

An offshore plant exposes environmental threats which are typhoon, tidal wave and etc., also the offshore plant exposes artificial threats by fire and collision of ship. In this paper, we design an IT conversion remote monitoring system for protection from environmental and artificial threats using camera, AtoN AIS. The system helps to monitor possible situations around offshore plant remotely. Therefore, we handle the situations appropriately and manage the offshore plant safely.

The biggest change in modern society because we will transition to a ubiquitous environment. Changes in the environment has become a crucial instrument that finally opens the era of convergence management through integrating the various fields in their own business. The desire of consumers to new innovative products appears to be a constant thing companies are constantly trying to respond to these changes, there may not be a problem for the convergence of sustainability management company in the end. In this study, based on the convergence of corporate management need to be a fusion component of corporate management to examine whether any impact on the quality of innovation. Results showed that the fusion management components that affect both internal factors and external factors, core factors quality improvement. Internal factors detailed in the convergence management leadership, risk management factors showed a positive external factors affecting appeared to affect positively the knowledge-sharing factors, infrastructure factors. Finally, core factor is technology factors, educational learning factors showed a positive impact. This results suggest that be a big impact factors of competitiveness of enterprises through convergence management in the future and will serve as the strategic basis for the convergence of future corporate management.

The aim of this study was to develop a simple, environmentally friendly synthesis of silver nanoparticles (SNPs) without the use of chemical reducing agents by exploiting the extracellular synthesis of SNPs in a culture supernatant of Bacillus thuringiensis CH3. Addition of 5 mM $AgNO_3$ to the culture supernatant at a ratio of 1:1 caused a change in the maximum absorbance at 418 nm corresponding to the surface plasmon resonance of the SNPs. Synthesis of SNPs occurred within 8 hr and reached a maximum at 40-48 hr. The structural characteristics of the synthesized SNPs were investigated by various instrumental analysis. FESEM observations showed the formation of well-dispersed spherical SNPs, and the presence of silver was confirmed by EDS analysis. The X-ray diffraction spectrum indicated that the SNPs had a face-centered cubic crystal lattice. The average SNP size, calculated using DLS, was about 51.3 nm and ranged from 19 to 110 nm. The synthesized SNPs exhibited a broad spectrum of antimicrobial activity against a variety of pathogenic Gram-positive and Gram-negative bacteria and yeasts. The highest antimicrobial activity was observed against C. albicans, a human pathogenic yeast. The FESEM observations determined that the antimicrobial activity of the SNPs was due to destruction of the cell surface, cytoplasmic leakage, and finally cell lysis. This study suggests that B. thuringiensis CH3 is a potential candidate for efficient synthesis of SNPs, and that these SNPs have potential uses in a variety of pharmaceutical applications.

The study aims to develop the indicators to evaluate archival information service environments for the disabled in archives. Based on the barrier-free authentication indicators, the study analyzed the main concepts of archival information services and the service movement lines of users in archives. The study developed new indicators to evaluate records and information service environments by synthesizing all the concepts of information services, service movement lines, barrier-free authentication indicators and the regulations related to archival information services. The study can contribute to find out core problems of service environments in archives through utilizing the new indicators and scales, and to suggest alternatives to improve the environmental conditions for the disabled.

최근 e-러닝 산업 및 기술에서 큰 화두는 디지털 융합과 현상이라고 할 수 있으며, 이러한 융합화 시대를 향한 진화의 핵심적인 요구사항은 OSMU 이다. 현재까지 e-러닝 산업은 표준화 활동을 통해 디지털 융합화를 실현하고 있으며, 미국 ADL의 SCORM이 사실상의 표준으로 인식되고 있다. 하지만 기존 웹 기반의 e-러닝 환경은 학습을 할 때 컴퓨터에 의존함으로써 실질적인 디지털 격차를 극복하기에 한계가 있다. 이에 본 논문에서는 보다 실생활에 근접한 DiTV용 T-러닝 학습 환경에의 적용을 위하여 이미 작성된 SCORM 기반의 학습 콘텐츠 메타데이터를 DiTV용 TV-Anytime 메타데이터로 변환하여 상호운용성, 재사용성 및 고 이용성 등을 가능하게 하는 시스템의 설계를 제안하고자 한다. 이 시스템을 통하여 PC 에 익숙하지 못한 사람들을 DiTV 앞에서 더욱 편한 학습 기회를 제공할 수 있을 것이다.

도시민들의 다양한 여가활동의 요구로 날씨와 계절에 상관없이 즐길 수 있는 운동으로 실내 스포츠 수요가 급증 하고 있다. 이에 스포츠 클라이밍의 인기 또한 증가하고 있는 추세이다. 또한, ICT기술의 발전으로 스포츠 산업에서도 ICT융합이 활발히 진행 중이다. 이에 실내 스포츠 클라이밍은 ICT기술 융합이 용이한 환경으로 컴퓨팅 환경을 구성하기 적합하다. 따라서 ICT융합 스포츠 클라이밍에 대한 새로운 신조어 스크린 클라이밍이라는 말이 나오고 이에 대한 인터랙티브 인공 암벽이라는 연구가 진행 되었다. 하지만 스포츠 클라이밍에서 사용되는 모바일 애플리케이션의 연구는 현저히 부족한 상황이다. 현재 상용화되어 있는 클라이밍 애플리케이션은 일방적인 정보제공에 그쳐 정보의 확장 및 재생산이 어렵고, 자신의 기록 측정 및 정리 과정이 번거롭다는 한계가 있다. 이에 본 논문에서는 인터랙티브 인공 암벽 활용을 위한 모바일 애플리케이션을 제안하고 구현한다. 즉, 사용자가 실제로 쉽고 편리하게 등반 루트와 등반 기술에 대한 정보를 제공받고 자신의 등반 기록을 관리할 수 있는 사용자 친화적 클라이밍 모바일 애플리케이션을 구현한다.

현재 대부분의 패션 추천시스템은 프로필 또는 설문조사를 통해 수집 된 사용자의 정적 정보를 활용하고 있다. 사용자의 정적 정보는 매우 한정적이며 이를 활용하여 다양한 환경에 적합한 패션 코디셋을 추천하기란 매우 어렵다. AI코디네이터와 사용자간의 지속적인 대화가 담긴 대화질의 데이터셋을 사용하면 사용자의 상황과 환경을 고려하여 개인에게 최적화 된 패션 코디셋을 추천할 수 있다. 본 논문에서는 한국전자통신연구원(ETRI)에서 제공하는 AI 패션 코디네이터와 사용자의 대화 정보가 담긴 FASCODE 데이터셋을 사용하여 사용자의 발화에 따라 의상을 추천하는 인공지능 모델을 위한 대화질의 데이터 전처리 방법을 제안한다.

IoT(Internet of Things) 기기를 활용하는 분야가 증가함에 따라 스마트 팩토리, 스마트 그리드 등 융합환경이 발전되었으며, 융합환경이 상호연결되는 IoBE(Internet of Things Blended Environment)가 조성되고 있다. 그러나, IoBE 구성요소가 복잡해짐에 따라 공격 표면이 증가하고, 기존에 알려진 보안위협이 융·복합되어 새로운 형태의 보안위협인 복합위협(BT, Blended Threat)이 발생할 수 있다. BT는 다양한 보안위협이 복합적으로 연계되어 발생함에 따라 예측하여 대응하기에 기존 보안위협보다 상대적으로 어려우며, 이에 대응방안 간의 조합을 통해 보안위협에 유동적으로 대응하는 동적 보안 프레임워크가 필요하다. 따라서, 본 논문에서는 BT에 대한 대응방안 동적 조합 프레임워크를 제안한다.
