본 연구에서는 라즈베리파이에 부착된 카메라로 사람을 얼굴을 인식하는 영상처리기법을 활용하여 가정용 로봇을 제작하였다. 라즈베리파이에 부착된 카메라를 통해 실시간으로 영상을 입력받아서 사람의 얼굴을 인식하게 한 후 결과에 따라 스마트냉온풍기의 동작을 구분한다. 이는 로봇이 사람이 없는 곳에 냉온풍기를 동작하지 않고, 사람이 있는 곳에만 냉온풍 동작을 하게 함으로써 에너지 활용 효율을 높일 수 있을 것으로 기대된다.

자전거 등하교 및 출퇴근족의 안전을 위하여 방향 표시등의 기능은 반드시 필요하다. 본 연구에서는 아두이노를 활용하여 조립식 자전거에 방향 표시등 기능을 개발하였다. 아두이노의 간단한 기능을 통해 핸들에 스위치를 부착하여 방향 표시등을 켜고 끄게 할 수 있다. 또한 간단한 기능이므로 자전거를 가지고 있는 사람들이 스스로 DIY를 하여 제작할 수 있는 메이커 활동으로 적합하다고 판단된다. 본 논문에서 제안된 기능을 통하여 자전거에 필요한 서비스를 많이 부착할 수 있는 가능성을 열어두었다.

Technical high school aims at educating students to acquire fundamental skill and technology required for being competent technicians, to be creative in adjusting themselves to the changing industrial society, and to do self-realization and find their ways toward the future on their own. To attain that goal and maximize learning effect, mathematics education is very important as prerequisite learning for technical subjects, as most technical courses in technical high school are basically based on mathematics. The purpose of this study was to discuss how mathematics education could be successfully linked to technical courses in an attempt to make it function properly as prerequisite learning for major subjects and facilitate students' technical learning. For that purpose, what problems the mathematics components of major subjects and the curriculum had was examined and the way to offer better education was presented. And there are some suggestions regarding mathematics education: First, technical mathematics should be newly inserted into technical high school curricula to help students learn major subjects in more efficient way. Second, most technical high schools are expected to just require tenth graders to complete a 10-stage mathematics course. In that case, they might find difficulties in learning major subjects when they are in their 11st and 12th grade. The curriculum should be designed to have 11st and 12th graders take mathematics education. Third, many students find a job after graduation, but the growing number of students go on to university to receive more education in the same field. Accordingly, there is a need to enlarge continuous progress plan, rather than completion-type one, to make students well-grounded technically. And mathematics should be taught in more classes as prerequisite subject for major courses. Fourth, mathematics elements necessary for each major subject should be outlined and announced to schools so that they could reorganize mathematics and major courses appropriately.

Purpose - This study aims to advance our knowledge about factors influencing technical startup performance through analysing technical startup process empirically. This study was conducted to focus on industry structure(industry growth rate, competitive intensity, and enter barriers), technology characteristics(technical excellence and wide range of technical application), and the performance in the technology-based start-ups. Specifically, analyzing moderating effect of technology-marketing strategy, this studied how moderating variables affect technical startup performance under industry structure. Research design, data, and methodology - The subject of this study was technology-based start-ups company that received technology transfer from public organization. The development of the paper model is based on the literature of the preceding research analysis in technology commercialization, performance of technology-based start-ups, and marketing strategy. This study has a construct that was defined in the previous studies, such that technology marketing strategy was defined into the two ways of being broad or narrow in strategic application. From November 3. 2015 to December 22, 220 questionnaires were distributed with targeting to start-up companies in technology-based. 188 responses were collected for empirical analysis except the missing and wrong value responses. This data were used for structural equation modeling and regression analysis. Results - The results of this study are as follows. First, as industry structure variables influencing on performance(technical, financial) of technology-based start-ups, industry growth rate, competitive intensity and enter barriers of variables were verified; high growth rate has more positive effect on performance than low growth rate, competitive low intensity has more positive effect on performance than competitive high intensity, low enter barriers have more positive effect on performance than high enter barriers. Second, as technology characteristics variables influences on the performance(technical, financial) of technology-based start-ups, technical excellence and wide range of technical application of variables were verified ; technical high-excellence has more positive effect on performance than technology low-excellence, wide range of technical application has more positive effect on performance than narrow range of technical application. We also find that technology marketing strategy(broad/narrow) in moderating factors on performance (technical, financial) is as follows. Analyzing the moderating effect depending on technology marketing strategy(broad/narrow), application of technology, and the types of technology strategy(broad/narrow) were revealed that broad marketing strategy had a more significant effect on performance of technology-based start-ups. With AMOS, the relevancy of the study model revealed higher for broad technology-marketing strategy than narrow technology marketing strategy, and the explanatory power revealed to be 6.4% higher in broad marketing strategy than narrow marketing strategy. Conclusions - This study confirmed that industry structure and technology characteristics are important factors influencing the performance of technology-based start-ups. Technology-marketing strategy affects the performance of technology-based start-ups between industry structure and technology characteristics. According to additional analysis, moderating variables and technology-marketing strategy are important factors influencing the performance of technology-based start-ups under industry structure and technology characteristics. Broad type of technology-marketing strategy has more attractive industry structure and excellent technology characteristics than narrow types of technology-marketing.

The BIM libraries and technical contents in order to develop common technical standards that reflect the contents for a BIM design support should be based. It is essential to redress the technological burden on design office requirements. The technical contents consisted of Material Information, Standard Details and Cost Information are made by system of standard classification. By connecting BIM libraries with each of information including the contents, it derives the consistent BIM data application through the integrated model. In addition, we look forward to introducing and applying BIM more easily through securing common technical contents which remove the pressure of engineering developments of each individual architectural design office and prevent overlapping investments.

The periodic technical vehicle inspection is to prevent the accident through the finding and fixing the defects of the vehicle. The periodic technical vehicle inspection in Korea was studied for assessing the adequacy of the inspection frequency. The inspection frequencies of many countries including EU, USA and Japan were compared. The average mileages by the vehicle usage and type were represented. The warranty period and recommended replacement period of parts of the domestic auto makers was studied. Currently, the inspection frequency for the periodic technical vehicle inspection in Korea is appropriate. The pass-fail rate and the cost-benefit analysis for the periodic technical inspection in Korea will be needed in the decision making process for the inspection frequency.
