  • 지능정보기술과 에너지기술의 융합은 단순히 기술 자체 뿐 아니라 사회, 제도, 조직 전반의 변화를 수반하기 때문에 수많은 이해관계자들에게 영향을 미친다. 따라서 자원개발과 발전, 석유화학 중심의 전통 에너지 산업에 대한 경로 의존성에서 벗어나 새로운 산업을 창출하기 위해서는 미래에 도달하고자하는 선호 미래를 먼저 그리고 이를 실현하기 위한 전략을 고민하는, 백캐스팅(Backcasting) 관점의 접근이 필요하다. 본 연구에서는 이러한 백캐스팅 관점에서 지능정보기술이 가져올 미래 에너지 산업의 변화 양상을 살펴보고 국가 관점에서의 에너지 정책 목표 달성, 그리고 각 이해관계자들의 이익을 동시에 만족시킬 수 있는 미래 에너지 서비스 모델을 도출하였다. 이후, 미래 에너지 서비스가 실현되기 위한 기술적 선결 조건을 분석하고, 세부적인 구성 기술과 현재 시점에서 중점 R&D가 필요한 분야를 제시하였다.

  • 본 연구는 경도의 지적장애를 가진 20대 대학생이 다양하게 누운 자세변화 따른 복합적 폐활량에 미치는 영향을 알아보고자 하였다. 경도의 지적장애를 가진 20대 남자 대학생 20명을 대상으로 실험에 참여하였다. 실험 대상자들은 누운 자세, 오른쪽 옆으로 누운 자세, 원쪽 옆으로 누운 자세, 엎드러 누운 자세에 따라 폐기능 측정기를 이용하여 폐활량을 평가해 보았다. 자료분석은 SPSS 18.0 버전을 이용하여 실험 대상자의 자세변화에 따란 호흡변화를 분석하기 위해 일요인 반복측정 분산분석으로 검증하였다. 결과는 오른쪽 옆으로 누운 자세에서 폐활량이 가장 크게 나타났고 엎드러 누운 자세에서 가장 낮게 나타났다. 이 연구를 통해 경도의 지적장애인이 일상이나 임상에서 침상생활을 할 때 취침에서 가장 안정된 호흡능력을 확보할 수 있는 이상적인 누운 자세를 제시하고 효율적 환기능력에도 긍정적인 효과를 나타날 것으로 생각된다.

  • The ultrastructure in the beef muscle of the electro-magnetic resonance and air blast freezing during the frozen storage, and the changes in the quality characteristics after thawing were evaluated. The size of ice crystal was small and evenly formed in the initial freezing period, and it showed that the size was increased as the storage period was elapsed (p<0.05). The beef stored by the electro-magnetic resonance freezing showed the size of ice crystal with a lower rate of increase than the air blast freezing during the frozen storage. The thawing loss of beef stored by the electro-magnetic resonance freezing was significantly lower than the air blast freezing during frozen storage (p<0.05), and it showed that the thawing loss of the round was higher than the loin. Water holding capacity decreased as the storage period became longer while the electro-magnetic resonance freezing was higher than the air blast on 8 month (p<0.05). As a result of sensory evaluation, the beef stored by the electro-magnetic resonance freezing did not show the difference until 4 months, and it showed higher acceptability in comparison with the beef stored by the air blast freezing. Thus, it is considered that the freezing method has an effect on the change in the ultrastructure and quality characteristics of the beef.

  • A road energy harvester was designed and fabricated to convert mechanical energy from the vehicle load to electrical energy. The road energy harvester is composed of 20 piezoelectric materials. This study attempted to evaluate output depending on pavement materials when paving road piezoelectric energy harvester in the road. Harvester is the bender type and is the method of supporting the both ends of piezoelectric material and applying the load in the middle part. Harvester was paved in the type paved with asphalt, type paved with cement and in the exposed type not covering the top of harvester. The output characteristics were compared and evaluated depending on changes in vehicle load and vehicle speed changes. As vehicles, truck (11.9 ton), SUV(1.6 ton) and sedan (1.5 ton) were used and the output characteristics when driving at the interval of 10 km/h from 10 km/h to 100 km/h were evaluated.

  • 4차 산업혁명 시대에 인공지능의 중요성은 나날이 커지고 있으며, 인공지능 교육이 미래에 큰 혁신을 가져오리라는 것에 대해 이견이 없다. 인공지능 교육을 위해 다양한 시도가 이루어지고 있지만, 인공지능 교육에 대한 경험이 없는 학생들은 인공지능을 어렵고 두려운 대상으로만 인식하고 있다. 이에 본 연구에서는 인공지능 융합교육을 시행한 후에 학생들의 인공지능에 대한 인식 변화를 분석하였다. 인공지능 융합 교육을 초등학교 6학년 학생들을 대상으로 6차시 동안 진행하였으며, 인공지능에 관한 관심, 인공지능이 가지고 올 변화, 인공지능 교육에 대한 이해 등 인공지능 인식조사 설문지를 바탕으로 사전-사후검사를 진행하였다. 그 결과 모든 요소에서 인공지능 융합 교육을 통하여 인공지능에 대한 인식 정도가 향상되었다는 유의미한 결과를 확인하였다. 인공지능 융합 교육이 사회적인 요구와 미래 학생을 위한 교육으로써의 역할을 충실히 수행하기 위해서는 다양한 인공지능 융합 교육 프로그램의 개발이 필요하며, 이를 바탕으로 학생 중심의 교육 실행이 필요할 것이다.

  • This study analyzes recent trends in fashion retailing instigated by the fourth industrial revolution and approaches the trends in terms of the convergence of big data and artificial intelligence. The findings are as below. First, companies like 'Edited' and 'Stylumia' offer solutions that support the strategic decisions of fashion brands and fashion retailers by analyzing big data using artificial intelligence. Second, the convergence of big data and artificial intelligence scales personalized service on the web as examples of 'Coded Couture', 'StitchFix', and 'Thread'. Third, the insights gained from artificial intelligence and big data help create new fashion retailing platforms such as 'Botshop' and 'Lyst'. Last, artificial intelligence and big data assist with design. 'Ivyrevel' designs digital fashion, assisted by a macroscopic perspective on fashion trends, market and consumers through the analysis of big data. The Fourth Industrial Revolution brings changes across all industries that will likely accelerate. The fashion industry is also undergoing many changes with advancements in scientific technology. The convergence of big data and artificial intelligence will play a key role in the future of fast-moving industry like fashion, where fickle tastes of consumers are the main drivers.

  • The purpose of this study was to investigate the effects of turmeric intake and weight training on blood alcohol concentration, liver enzyme levels of and their effects on health promotion in adult males. There was no significant difference of taking turmeric powder combined with weight training exercise on blood alcohol levels in adult men who consumed alcohol on a regular basis. There was also no change on the change of body composition. The results were collected from elite athletes that had spent more than 10 years in their respective sports so it is difficult to observe any significant results from 8 weeks, short-term exercises of 1RM 70~80%, 3 times per week. In the next study, it is necessary to divide the subjects into more diverse groups and subject them by varying amounts of turmeric intake, exercise, etc., in order to fully study and understand the effects on blood alcohol level, change, and health promotion. Consequently, this study demonstrated there were no significant differences in the effects of continuous drinking habits of adult men's turmeric powder intake and weight training exercise on changes in GOT, GPT, γ-GTP, and blood alcohol concentrations. Moreover, health improvements themselves didn't affect changes in body composition.

  • Construction firms have long sought success in the global construction market through diversifying revenue sources and project portfolios. The volume of international contracts has contributed to firms' sustained growth by mitigating the impact of the domestic market's cyclical nature. In spite of the importance of international construction, the uncertainty and dynamic changes surrounding global construction pose serious threats to global contactors. Over the last decade, the international construction industry has changed drastically in many ways, particularly including financial resource diversity, competition rules for the selection of contractors, and the terms of delivery systems requiring more competent total service providers. This paper investigates the important changes for global contractors through various documentation analysis as well as in-depth interviews with industry experts. This paper then analyzes the common strategies and lessons obtained from the cases of leading global contractors that have sustained their growth in the competitive global construction during the last decade. In addition, the authors further analyzed the comparisons between those firms and Korean contractors to discern any difference in sustaining their growth in the competitive market. It was found that those leading firms were quite proactive and responsive to changing markets by diversifying their market revenues to stabilize their revenue structure and enhancing their competency through a wide range of 'business convergence'. In addition, they significantly increased their upstream/downstream functional capabilities; hence becoming more competent service providers, able to grow in these rapidly changing market conditions. Finally, this paper benchmarks the critical strategies that support growth, which in turn can provide a strategic guideline for expansion into the global construction market.

  • The purposes of this study are predictions of the changes in the section geometry and determination of the initial cross section so that opposite side in height direction is exactly parallel after coiling process. Finite element analysis is carried out for the calculation of the sectional changes for mold spring item. Analysis results reveal that the slope of the top and bottom sides varies in the range of 5 to 8 degrees and the amount depends on the dimension of the outer diameter. The slopes of the sides should be defined first among design variables.
