정보통신 분야와 관련하여 현재의 우리 사회에서 보여지고 있는 큰 특징중의 하나는 급변하는 IT환경에 대처하기 위한 노력일 것이다. 다양하게 나타나고 있는 비즈니스 환경에 대처하기 위해 기업들은 스토리지 및 서버 등과 관련된 IT 관련 구입에 꾸준히 비용을 투자하고 있다. 이같은 상황들은 기업입장에서는 기업의 생존과도 밀접하게 연관되어 있기 때문일 것이다. 이에 대한 해결책으로 최근 클라우드 컴퓨팅 서비스에 대한 연구가 활발히 진행되고 있다. 클라우드 컴퓨팅 서비스가 시장에 등장함에 따라 IT 자산과 관련된 개념은 소유에서 서비스를 이용한다는 의미로 변화되고 있다. 이러한 추세를 반영하듯 많은 관련 기업들이 클라우드 서비스를 제공하고 있다. 본 논문에서는 클라우드 컴퓨팅 서비스에 대한 일본의 산업 전망 및 사례들에 대해 연구하였다.

Recently, small and medium-sized rahmen-type bridges have been developed as a technology that ensures the stability of structural behavior and the safety of use at the same time by using efficient and economical materials that make up the convergence section of reinforced bar, structural steel and concrete. This study is about a rahmen-type structure applied with the installation and dismantling of the strut. It improves the serviceability of the structure by forming multi-points and efficiently applies the convergence section of structural steel and concrete materials to the structural system changes to induce the displacement improvement effect additionally. By constructing mock-up models for the beam-column joint, the displacement was calculated and compared, and this was compared and analyzed by numerical analysis. The final displacement showed an improvement effect of 13.46% to 36.28% based on the vertical displacement of the existing structure without struts through the experiment of the mock-up models. As a result of analysis by numerical analysis method, the displacement improvement effect of 42.89% could be derived.

The composition of convergence cross-section of the material is a technique that provides reasonable design and construction of structures. It is frequently used in medium-sized bridges and architectural structures. However, the structural behavioral spare capacity enhancement of the structure by the application of the convergence cross-section is still limited by the expandability due to the limiting state of each material. In order to overcome these limitations, this study reasonably analyzed the construction stages before and after the convergence cross-section constructed and developed a technique for forming multi-point boundary conditions using struts, which are compression members. Based on the existing cases, a reasonable construction step for forming the material composite section of the entire structural system of the structure was derived, and a numerical analysis model for a specific part was constructed to analyze the behavior of the strut application. As a result of this study, the effect of reducing the sectional force of 7.40% in beam-column joint and 6.31% in the center of girder was derived, and the deflection, which is a measure of the serviceability of the structure, improved by 54.41% from the installation and dismantling of strut members at each construction stage.

Purpose: The purpose of this paper is to analyze the technology convergence and its characteristics, focusing on the defense technologies in South Korea. Methods: Patents applied by the Agency for Defense Development (ADD) during 1979~2019 were utilized in this paper. Information Entropy analysis has been conducted on the patents to analyze the usability and potential for development. To analyze the trend of technology convergence in defense technologies, Social Network Analysis(SNA) and Association Rule Mining Analysis were applied to the co-occurrence networks of International Patent Classification (IPC) codes. Results: The results show that sensor, communication, and aviation technologies played a key role in recent development of defense science and technology. The co-occurrence network analysis also showed that the convergence has gradually enhanced over time, and the convergence between different technology sectors largely emerged, showing that the convergence has been diversified. Conclusion: By analyzing the patents of the defense technologies during the last 30 years, this study presents the comprehensive perspectives on trends and characteristics of technology convergence in defense industry. The results of this study are expected to be used as a guideline for decision making in the government's R&D policies in defence industry.

This study aims to analyze product samples of convergence of fashion and technology, as convergence is a major trend in the age of digital paradigm, and to propose desirable directions of development for technology convergence in fashion design in the future. With bibliographic research as well as internet search of the cases of development and commercialization of convergence of fashion and technology from the 1960s, when wearable computers were first introduced as an early development form of convergence, to the present, it becomes possible to classify these cases into three groups: functionally oriented one, aesthetically oriented one, and one that combines function and aesthetics. The pros and cons of each group of these cases are discussed and an evolutionary trend is observed from the earlier stage of convergence with functionally oriented cases which tried to achieve specific purposes of the time to the later stage of convergence with emphasis on both function and aesthetics which reflects the sensitivity of the general wearers. When three groups are plotted in the positioning map with one axis of function-aesthetics and the other of industry-fashion designer, however, all three are located outside of the two axes, suggesting these elements are not very well combined. In order for the products of the fashion-technology convergence in the future to receive favorable response from the consumers, it is necessary for the fashion industry to develop a close collaboration with companies of digital technology and the convergence products not only will have to provide functional benefits of the new technology but also to satisfy the aesthetic demands of the wearers.

전자산업은 많은 수익과 일자리를 제공하고 다양한 융 복합 분야에서 중요한 역할을 담당하고 있다. 최근 IT 융합기술 발달과 세계경제 통합으로 산업전략이 변하면서 ICT산업의 글로벌가치사슬(GVC)이 확대되고 있다. 글로벌가치사슬은 R&D, 제조, 판매, A/S 등 부가가치 생산을 위한 기업 활동의 모든 과정이 세계적인 차원에서 이루어지는 구조이다. 본 연구의 목적은 전자산업의 GVC 현황과 국내 대표적인 전자업체인 삼성전자와 LG전자의 GVC 추진사례를 분석하는데 있다. 전자산업의 GVC는 1980년대 이후 발전하기 시작하면서 미국과 캐나다 등 선진국에 생산기지를 구축하였다. 2000년 이후에는 인건비 등 원가절감을 위해 중국, 대만, 인도 등 저비용 국가로 이전하였다. 최근에는 중국의 인건비 및 생산비 급상승으로 인해 상대적으로 저렴한 베트남으로 생산기지를 이동하는 현상이 나타나고 있다. 국내 전자업체들은 지속적으로 성장하기 위해 수출대상국을 상대로 브랜드 및 품목별 마케팅을 실시하는 등 새로운 전략을 수행해야 한다.

Bacterial cellulose (BC) has played important role as new functional material for food industry and industrial products based on its unique properties. The interest in BC from static cultures has increased steadily in recent years because of its potential for use in medicine and cosmetics. In this study, we investigated culture condition for BC production by Acetobacter sp. F15 in static culture. The strain F15, which was isolated from decayed fruit, was selected on the basis of BC thickness. The optimal medium compositions for BC production were glucose 7%, soytone 12%, $K_2HPO_4$ 0.2%, $NaH_2PO_4{\cdot}_2H_2O$ 0.2%, lactic acid 0.05% and ethanol 0.3%, respectively. The strain F15 was able to produce BC at $26^{\circ}C-36^{\circ}C$ with a maximum at $32^{\circ}C$. BC production occurred at pH 4.5-8 with a maximum at pH 6.5. Under these conditions, a maximum BC thickness of 12.15 mm was achieved after 9 days of cultivation; this value was about 2.3-fold higher than the thickness in basic medium. Scanning electron micrographs showed that BC from the optimal medium was more compact than plant cellulose and was reticulated structure consisting of ultrafine cellulose fibrils. BC from the optimal medium was found to be of cellulose type I, the same as typical native cellulose.

경기북부 지역 내 섬유패션산업은 23개 제조업종 중 가장 큰 비중(17.7%, 10인 이상 사업체 수 기준)을 차지하는 중추 기반산업이다. 하지만 소규모 공정별 임가공 업체가 대다수이고 최근 이 임가공업체에 오더를 주던 중대형 벤더의 해외이탈이 가속화됨에 따라 오더가 급감하고 있고 이로 인해 투자 감소로 이어지는 악순환 고리가 고착화되어 가고 있다. 이에 본 연구는 이러한 악순환 고리를 끊고 경기북부 섬유패션산업의 구조 고도화를 위한 정책요인을 분석하고 구체적 정책 제언을 위해. 각종 산업통계 데이터를 조사, 분석하여 관련 산업규모의 변화추이, 경영환경 변화 등을 파악한 결과와 관련 문헌조사 등의 선행연구결과 및 산 학 연 관 전문가의 의견조사를 바탕으로 AHP 연구모형(4개 계층, 36개 요소)을 설계하였고. 계층 간 및 계층 내 요인(요소)들 간 쌍대비교를 통해 상대적 중요도 및 우선순위를 도출하였다. 또한 이 연구모형 및 그 도출 결과를 반영한 섬유패션산업의 비전, 전략, 핵심과제 및 세부추진과제를 구체적으로 제안하여 본 연구결과의 유용성 및 활용성을 제고하였다.

본 연구는 뇌졸중 환자를 대상으로 가상현실 프로그램에 대한 융복합적 효과를 알아보기 위해 메타분석을 실시하였다. PICOS 기준에 따라 국내 문헌을 검색하여 '뇌졸중', '가상현실 프로그램' 관련하여 최종 9편의 연구를 선정하였다. 개별 연구물의 비뚤림 평가는 각 연구의 설계에 따른 평가 도구를 이용하여 실시하였다. CMA 프로그램을 이용하여 메타분석의 효과크기를 산출하였다. 조절효과분석은 하위그룹분석과 메타회귀분석으로 실시하였다. 가상현실 프로그램의 일상생활활동 능력에 대한 전체 효과크기는 Hedges's g=0.302(95% CI: 0.064~0.540)이었다. 따라서 가상현실 프로그램은 뇌졸중 환자의 일상생활활동 능력을 증가시켜 가상현실 산업과 의료 보건 산업을 융복합한 의료산업에 긍정적인 영향을 제공할 수 있다.
