친환경 시대로 나아가는 현재, 능동소음제어는 저주파소음을 줄이기 위한 좋은 방법이다. 또한 수동소음제어만으로 선박소음을 제어하기에는 물리적인 무게가 심각히 가중되어 한계를 가지게 된다. ANC 시스템은 이러한 문제를 해결해 줌과 더불어 다양하게 변화하는 환경소음까지 줄여주는 특성을 가지고 있다. 우리는 본 논문에서 선박의 환경소음을 줄이기 위하여 LMS 알고리즘과 신경회로망 알고리즘을 기반으로하는 ANC 시스템을 제안한다. 먼저 선박과 유사한 유도전동기의 소음을 측정하고 다음으로 ANC 시스템을 위한 LMS 구조를 구축한다. 그리고 소음의 비정치와 불확실성 때문에 단층 퍼셉트론 모델로 디자인된 신경회로망 알고리즘을 추가하여 실시간으로 소음을 줄이도록 하였다. 이 하이브리드 ANC 시스템은 최급강하기법의 방법으로 파라미터 값들이 온라인으로 실시간 추정되며, 제안된 ANC 시스템은 컴퓨터 시뮬레이션을 이용하여 그 성능을 분석하였다.

업사이클링 산업은 관련 국내 시장의 규모가 해외 시장보다 현저히 느려 미약적인 성장을 거듭하였지만 2016년 기준 약 200억원까지 달하는 것으로 분석되어 관련 사업이 지속적으로 발전할 것으로 예상된다. 역사성을 지속시키되 창의성을 더한 희소성, 친환경 의식으로 감성적 '가치소비' 트렌트와 맞물리면서 업사이클링 산업은 확산될 것으로 기대된다. 이에 따라 업사이클링 시장 환경을 되살리고 새로운 부가가치를 창출하는 새로운 신 시장으로 다가오고 있다. 이러한 배경에서 본 연구는 국 내외 업사이클링을 기반으로 한 도시재생 사례를 분석하는 연구로서 이를 통해 공공 환경 디자인에 업사이클링이 적용될 수 있는 기초 연구로서 의의가 있다.

4차 산업혁명의 초연결/초지능 사회가 현실화 되면서 모든 제품이 배터리에 연결되는 사물배터리(battery of things) 시대가 열리고 있다. 이에 따라 기존의 정형화된 에너지 저장 장치를 넘어 전자기기 각각에 걸맞은 스펙과 기능을 갖는 맞춤형 전지 개발이 화두이다. 특히 구부러지거나 변형될 수 있는 웨어러블 전자기기를 구동하기 위해서는 기계적인 변형에 안정한 에너지 저장 장치가 필요하다. 또한 다양한 기능(투명성, 전기변색, 자가치유형, 친환경 등)을 갖는 지능형 전자기기가 개발됨에 따라, 이와 동등한 기능을 갖는 에너지 저장 장치도 요구되고 있다. 나아가 각각 개발된 웨어러블/다기능성 전자기기와 에너지 저장 장치를 어떻게 통합시킬지에 대한 연구도 활발히 이루어지고 있다. 본 기고문에서는 기계적 안정성, 기존 소자와의 적합성, 나아가 신기능성까지 갖춘 차세대 다기능성 웨어러블 에너지 저장 장치를 소개하고 이를 위한 복합나노구조 합성 및 소자 디자인 전략에 관한 최근 연구 동향을 소개하고자 한다.

Today, modern people are exposed to various environmental pollutants such as harmful substances and stress, which can compromise health. Therefore, a healing culture that seeks to enjoy human life based on the healing of body and mind is attracting great attention. The purpose of this study is to develop environmentally friendly natural dyeing considering a healing concept with four elements: color, dye, material, and pattern. The research methods and scope are based on a theoretical review of healing and research on the literature of bedding related to natural dyes, national and international books, the Internet, etc., and naturally dyed bedding. This paper presents actual production research. The results of this study are as follows. First, the elements of color, dyeing, material and pattern were developed through the process of a bedding design development model that applies a healing concept and can be commercialized as a healing bedding product. Second, a healing color proposal was expressed in an intermediate color system of pink, ocher, lavender, and indigo colors for emotional stability, warmth, calmness, comfort and softness. Third, eco-friendly bedding using natural dyes with medicinal efficacy can obtain the healing effect of the natural treatment method, which can aid healthy sleep. Fourth, the pattern used in the bedclothes was a motif of Sarasa embroidery, flower embroidery, ribbon embroidery, and wave quilting motifs to provide psychological stability as a healing concept in the sleeping environment. The natural healing bedding with the healing concept proposed in this study has natural treatment that is beneficial to human health and the development of bedding with natural dyes will lead to an increase of demand for the sleeping environment.

Companies are facing challenges to have high competitiveness because of continuous oil price rising and CO2 emissions regulations. Thus, companies are trying hard to construct effective logistics and operation system to achieve high customer service quality and saving cost. Also the ec-friendly idustrial complex is needed. Busan is in process to construct GILC(Global Industry Logistics City) in west Busan province to achieve high competitiveness and support lack of industrial complex. To construct this kind of logistics industrial complex, it needs logistics system through proper policy and freight transportation co-operation. Especially, efficient management through logistics hierarchy construction in industrial complex is very important for low cost and eco-friendly point of view. Therefore, this paper aims to analyze logistics system and suggest operation model to present logistics complex construction base data.

Korea is promoted STEAM education since 2011. Furthermore, in high school education, based on the in-depth elective course's teaching and learning contents of science. The STEAM program can improve students' competence because it encourages to self-directed learning through the vocational project performance. Therefore, in this study, we researched a design education program for the experience of fusion and complex design based on STEAM education concept. We developed an education program to design insulation wall systems using up-cycling concepts to increase energy efficiency. As a result, the characteristics of the fusion education and the theoretical study about the learner-centered education curriculum, the analysis of the high school curriculum, the STEAM elements, The program was revised and supplemented through consultation with STEAM experts. In addition, the developed program was applied to high school students, and each step were analyzed based on the educational method theory. The following results were obtained. First, this study presented a program to cope with the needs of high school intensive education. Second, it provided learning motivation by combining flipped-learning as a way to train STEAM education contents. Third, it is required to develop differentiated and continuous program development and data sharing Fourth, in order to operate and promote the future environment design STEAM school, it is necessary to expand educational programs for high school students in the region through linkage with various universities.
