최근 유무기 하이브리드 전자소자의 발전과 더불어 스트레처블 태양광전지 기술이 개발되고 있다. 본 연구는 스트레처블 태양광전지에 대해 기술을 선도하는 국가나 기관을 파악하고 우리나라의 기술 수준은 어느 정도인지 분석하기 위하여, 특허 데이터를 기반으로 정량 분석을 수행하였다. 연구 결과, 스트레처블 태양광전지 기술은 전체 특허건수 1,747건 중에 48%를 차지하는 중국이 양적으로 우세한 것으로 나타났으며, 피인용도지수와 시장확보지수가 월등히 높은 미국이 질적으로 우수한 것으로 나타났다. 또한 상위 주요출원인 1~2위로 선정된 일본 국적의 화학물질 제조기업이 재료분야에서 기술을 선도하는 것으로 나타났다. 우리나라는 양적인 면과 질적인 면에서 모두 두각을 나타내지 못하고 있으며, 기업체의 참여도 저조하여 상업화 단계로 발전하지 못한 것으로 분석되었다. 단, 스트레처블 태양광전지 기술의 성장단계가 성숙기 단계로 진입하고 있고 기술 독점 여부가 낮은 것으로 나타났기 때문에, 선택과 집중을 통한 전략적인 연구개발 계획을 수립한다면 기회가 있다고 판단된다.

The purpose of this study is to analyze the facilitating and conflicting factors on the emerging technologies and trends predicted to impact future education in Korea. To do this, open online questionnaires on 20 emerging technologies and trends derived from a comprehensive literature review were completed by 24 experts in research, policy, schools, and corporate fields, and a content analysis of the collected qualitative data was conducted. As a result of the study, the effectiveness of the content and the maturity of technology were found to be the most important facilitating factors and obstacles. In addition, the potential for innovative teaching and learning methods and motivation, and the maturity and popularity of technology were found to be the main facilitating factors. On the other hand, health problems and negative effects on students in ethical aspects, the lack of research and development, and poor networks and infrastructures in terms of education environment were found to be the main impeding factors of emerging technologies and trends.

The aim of this study was to cluster according to the bone age of elementary school students in order to analyze the physique, physical fitness, and skeletal maturation of each cluter group and to provide basic data for the balanced development of elementary school students through data analysis. The subjects of this study were 2243 students aged 8 to 13 years, and the skeletal maturation were calculated by applying them to the TW3 method score conversion table after the X-ray films were taken. A total of 2 components in physique were measured using a stadiometer(Hanebio, Korea, 2021) and the Inbody 270(Biospace, Korea, 2019), and a total of 7 components in physical fitness, which included muscular strength(Hand Grip Strength), balance(Bass Stick Test), agility(Plate Tapping), power(Standing Long Jump), flexibility(Sit&Reach), muscular endurance(Sit-Up), and cardiovascular endurance(Shuttle Run) were measured as well. K-Means clustering method, cross-tabulation analysis, and one-way variable analysis(ANOVA) were conducted for data processing using the SPSS PC/Program(Version 26.0) and Bristics Studio Tool, and it was considered significant at the level of p< .05. The results of this study may be summarized as follow. First, as a result of clustering using three components of skeletal maturation: retarded, normal, and advanced, cluster 1(Retarded) showed excellence in muscular strength, balance, and agility. cluster 2(Normal) showed poor flexibility, whereas cluster 3(Advanced) showed excellence in muscular strength. Second, as a result of analyzing the differences in physique according to the clustering of elementary school students by their individual characteristics, cluster 3(Advanced) showed excellence in height, weight, and body fat percentage. Third, as a result of analyzing the differences in physical fitness according to the clustering of elementary school students by their individual characteristics, cluster 3(Advanced) showed excellence in Hand Grip Strength(Left, Right), whereas cluster 1(Retarded) showed excellence in Bass Stick Test, and cluster 3(Advanced) showed excellence in Standing Long Jump.

Recently as the advent of knowledge-based competition, the major industrialized countries including Korea, are expanding their R&D investment and promoting policies for diffusing of R&D performance. For this, NASA, DoD and such agencies in the United States define Technology Readiness Level (TRL) as a quantified indicator for performance management, and also impose Technology Readiness Assessment (TRA) as a evaluation system, that evaluates technology maturity using TRL. These tools are judged to be very effective in R&D projects especially with the object of practical use. When this concept is applied to the domestic national construction and transportation R&D project for the purpose of practical use, it is expected that the evaluation system overcomes its weakness of focusing only on academic results and improves significantly on intent of achieving practical use. Thus in this study, TRL/TRA implementation model of construction and transportation R&D project for achieving purpose of practical use is presented through an analysis of TRL/TRA concept and domestic national construction and transportation R&D project's characteristics and current evaluation/management system.

코로나19 이후 건축사업계 비대면 작업 등의 필요성이 대두되면서, 스마트건설 플랫폼 기술인 BIM(Building Information Modeling, 건설정보모델링) 활성화에 관한 목소리도 높아지고 있다. 최근 한국건설기술연구원에서는 공공분야 BIM 기술의 성숙도를 4단계(레벨1~4)로 봤을 때, 우리나라의 평가치는 '레벨1' 초보 수준에 머물러 있다는 진단을 냈다. 이미 '레벨3' 수준에 진입한 영국 등 선진국보다 뒤처져 있다는 분석인데, 이는 2D 환경을 기반으로 설계 또는 시공업무에 대해 제한적으로 BIM을 적용하면서, 일정 규모 이상의 설계BIM만 의무화한 수준이기 때문이다. BIM 트렌드가 '기술개발'에서 '활용' 단계로 넘어가는 과정 가운데 건축분야에서의 활성화 방안은 무엇일까. 월간 '건축사'가 'WBIM(주.더블유빔)'사(社)의 이재환 대표를 만나 BIM의 현장 활용성, 그리고 적용 측면에서의 현실문제 등에 대한 현장 이야기를 들어봤다. 각종 개발사업과 설계파트를 지원하며 BIM전문가로 활동해 온 이재환 대표는 "기획단계부터 BIM을 활용하면 사업 진행 전 과정에서 실시간 검증이 가능하고 동시에 각종 아이디어를 효과적으로 적용할 수 있다"면서도 "활용성을 확보하려면 업계뿐 아니라 발주처, 감독 등도 BIM에 대한 이해도를 높여야 한다"고 말했다.

In this paper, 228 cooperations supported by government were surveyed on the cognition levels of 5 factors for successful policies that support small business cooperation. Goal importance, awareness stage of importance, and current concerning level were scored to each question of factors. Using the results of previous studies, the maturity of each success factor, and the forecast time to mature and maturity of each question were analyzed. The results were compared with the results of a study precedent. Moreover, the changes in the participants' recognition levels were reviewed between before and after government's support. These comparative studies reflect government policies. Despite the government's supporting policies aided on building cooperation positively, the participants still worry about the decreasing government support. To allay these concerns, government policies should be implemented continuously to promote cooperation rather than a one-time support.

We Investigated the Two Additional Effects Regarding the Causal Relationship between the Perceived Risks of cloud Services on the Intention to use the Abandonment Option. First, we Empirically Tested the Moderation Effect of IS Maturity on the Causal Relationship between these Two Variables. Second, we also Investigated the Mediation Effect of Cloud Service Satisfaction on the same Causal Relationship. We could find the Moderation and Mediation Effect only on the Influence of Relational Risk (Which Occurs from the Power Abuse of Cloud Service Providers) on the Intention to sue the Abandonment Option. So, we have better Understanding when and how the Abandonment Option is Attractive in Reducing the Potential Influence of the Relational Risk in using the Cloud Services.

Internet of Things (IoT) is considered to be the next wave of Information Technology transformation after the Internet has changed the process of doing business. Since the domain of IoT ranging from the sensor technology to service to the users is wide, the structure of the research domain is not delineated clearly. To do that we suggest to use the Technology Stack Model proposed by Porter et al.(2014) to measure the maturity level of IoT in organizations. Based on the Stack Model, for the general understandings of IoT, we do keyword analyses on the academic papers whose major research issue is IoT. It is found that the current status of IoT application from the perspectives of cloud and big data analytics is not active, meaning that the real value of IoT has not been realized. We also examine the cases which deal with the part of cloud process which is crucial for value accrual. Based on these findings, we suggest the future direction of IoT research. We also propose that IT is to value chain what IoT is to the Stack Model to derive value in organizations.
