This study analyzes the business performance of research and development(R&D) and especially studies the effect of technology management activity and technology innovation competency on commercialization performance. According to previous studies, the technology management activity can be composed of technological innovativeness, analysis of market, R&D method, and appropriateness for commercialization plan. Also, the technology innovation can be divided into patent, R&D manpower, R&D investment ratio, production capability, and marketing capability. On the result of the analysis, all the components of technology management activity are positively related with commercialization performance. In case of technology innovation competency, however, only production and marketing capabilities have influence on the business performance. Especially, marketing capability controls the effect of technology management activities on the commercialization performance. Consequently, technology management is very important activity for SMEs to succeed commercialization and SMEs should collaborate with production and marketing departments from the early stage of R&D.

This study presents design, construction and testing of a immiscible two working fluids thermosyphon with water and FC-40 to prevent freezing of vehicle starting up at temperatures below freezing point of water. The two working fluids thermosyphon was experimentally investigated on the startup characteristics at low temperatures below 0°C and then the thermosyphon was stable during startup and operated reliable at temperature of –30°C. The testing also showed that the performance and characteristics of the two working fluids thermosyphon differ from the charging ratio and mixture ratio of the two working fluids.

A heat pipe heat sink which is possible to frozen start up at the lower than -20℃ by using a VCHP was designed, manufactured and tested. The VCHP uses water and nitrogen gas as the working fluid and non-condensable gas. The test results showed that the VCHP heat sink started up successfully at the range of -20 to -30℃ of the ambient temperature and 1000 to 2600W of the heat flow rate. The thermal resistance of the VCHP heat sink decreased as increased the heat flow rate and the ambient temperature since the active zone of VCHP increased.

회전축계가 거동시 지진하중을 받을때의 응답 거동을 조사하였다. 지진과 기동으로 인하여 회전축계가 불안정하다면, 과다한 진동이 발생할 뿐만 이니라 회정지계의 회전자가 고정자와 부딪혀 기계 성능을 발휘하지 못하게 할 것이다. 그래서 면진장치를 갖춘 기초에 지진동이 작용할 때에, 회전축계의 응답을 모사하였다. 거동시 회전축계의 과도 응답을 얻기 위하여 우선 회전축계의 운동방정식을 유도 하였다. 유도한 운동방정식은 비선형이어서 Runge-Kutta 수치해석법을 이용하여 응답을 계산하였으며, 기동 운전모드에 따른 거동뿐만 아니라 면진스프링의 강성을 매개변수로 취하여 회전축계의 응답거동을 고찰하였다.

우리나라 경제의 저성장이 지속됨에 따라 경제 활력을 위한 지원 정책으로 많은 창업이 이루어지고 있다. 그러나 디자인학과 학생들의 1인 창업의 창업률은 높지 않다. 특히 세계적으로 디자인전공 출신의 창업률이 높은데 비해 우리나라에서의 창업률은 그렇지 못하다. 그 이유로는 아이템의 부재였다. 아이템은 설문조사 결과 학생뿐 아니라 일반 창업자 역시 창업의 가장 중요한 요소로 꼽았다. 빠르게 바뀌는 소비자의 니즈와 시장 상황을 반영하기 위한 다양한 방법론들이 활용되고 있으나, 1인 창업에서 활용하기에는 효과적이지 못할 뿐 아니라 시간적, 물질적 한계를 지니고 있다. 특히 빠르고 긴밀하게 협업을 해야 하는 환경을 고려할 때 가장 어려운 부분이다. 이를 위해 문헌 연구를 통하여 UX에서 확장되어 나온 다양한 방법론들은 분석하여 UX 프로세스에서의 1인창업의 한계점을 극복할 수 있는 대안을 찾아보고자 한다.

하수처리과정에서 발생하는 슬러지의 부피를 줄이는 동시에 이들의 유기물 성분을 메탄 등의 바이오가스로 전환하기 위해 중온(35℃)에서의 혐기소화 공정이 널리 적용되고 있다. 혐기소화공정의 안정성이나 에너지 투입량 측면에서는 중온혐기소화가 적합하다고 알려져 있지만, 높은 유기물 부하량(organic loading rate, OLR)을 처리하기 위해 반응속도를 상승시키거나 SRT(sludge retention time)을 줄이기 위해 고온(55℃) 혐기소화를 적용하기도 한다. 고온 혐기소화공정을 새롭게 시작할 때 접종물을 기존의 고온 혐기소화공정으로부터 얻기 힘든 경우 중온혐기소화액을 고온에서 적응시켜 접종하기도 한다. 이때 온도를 적응시키는 방법에 따라 공정 효율이 달라지는데, 연구에서는 중온혐기소화액으로부터 고온 혐기소화 접종물을 제작하기 위한 방법으로 온도를 올리는 방법을 달리하였을 때 이들의 메탄 생산과 미생물 군집에 미치는 영향을 살펴보고자 하였다. 본 연구수행을 위해 광주 제 1 하수처리장에서 중온혐기소화액, 1, 2차 농축 슬러지 등을 샘플링 하여 두 대의 반응기(Working volume : 3L)를 설치하여 회분식(Batch)운전 후 연속교반탱크형반응기(CSTR)로 운전(SRT 20, 40일)하였다. 먼저 한 대의 반응기는 35℃에서 55℃로 한 번에 온도변화를 주었고, 다른 반응기의 경우에는 35℃에서 하루에 1도씩 올려서 약 20일에 걸쳐 55℃로 올린 뒤 55℃로 유지하였다. 반응기의 효율을 확인하기 위해 메탄 발생량, total solids (TS), volatile solids (VS), total chemical oxygen demand (tCOD), soluble chemical oxygen demand (sCOD), soluble components (protein, carbohydrate), pH 등을 측정하였으며, NGS (next generation sequencing)를 활용하여 혐기소화 전/후의 소화액의 미생물 군집변화를 알아보았다.

The purpose of this research is to go beyond the policy support of the traditional sixth industry and to build a business model of the farmers’ business by establishing the business model of the establishment of the sixth industry utilizing agricultural products of individual farmers. First, we defined the business model of the 6th agricultural industry, and secondly set up two models via FGI based on the 9 block model of BMC (Business Model Canvas), and applied feasibility, cost appropriate, differentiation point Through the establishment of hard-working business, sales consolidation, consumer-centric model set. Third, using the Delphi method in each area of 9 Block, the final 21 components were set. Through this BMC model, it was shown that discrimination and accessibility are important factors in the 6th agricultural field foundation business model.

Purpose – This study aimed to investigate the effect of entrepreneurial temperament (ET) such as innovativeness, risk-taking, and proactiveness in entrepreneur’s lifetime before start-up and the effect of social capital (SC) such as network ties and trustworthiness on entrepreneurial intention. Research design, data, and methodology - We examined the components of ET (innovativeness, risk-taking, and proactiveness) and components of SC (network ties and trustworthiness) through existing prior research and investigated the factors that affected entrepreneurial intention. The first hypothesis of this study was that entrepreneurial temperament will have a significant impact on network ties of social capital, and the second hypothesis assumed that entrepreneurial temperament will have a significant effect on the trustworthiness of social capital. Finally, the second hypothesis assumed that social capital will have a significant impact on entrepreneurial intentions. We collected 175 data using questionnaires for people who have not yet started a start-up. And we used the Structure Equation Modeling (SEM) to evaluate the collected data and to test the research model by the two step research procedure. Results – As a result, the innovativeness and proactiveness of ET have a significant effect on network ties and trustworthiness of SC, but the effect of risk-taking on risk-taking of SC is not significant. On the other hand, network ties and network ties of SC was revealed a significant effect on the EI. Conclusions - The implications of this article could be observed as mentioned in this paper. First, we found that entrepreneurial innovativeness and proactiveness are helpful in constructing SCs, but not risk-taking. These results demonstrated that ET of entrepreneurs is important factor in the formation of social capital. Second, the SC that an entrepreneur built before the start-up has a meaning for EI. In conclusion, ET was affected partially to EI mediated SC. It is academic in that ET and SC are independent from each other and have a mediating role between ET and EI, unlike those directly affecting EI. Although some important implications were found in this study, this study had some limitations and we hope that future research will be complemented.

Purpose – The present study aims to examine the relationship between small enterprise start-up preparatory factors and increases in sales and operating profits, which are business performances utilizing the National Survey of Actual Conditions of Small Enterprises conducted by the Small Enterprise, Market Service. Research design, data, and methodology – Start-up preparatory factors were divided into six types; business type, start-up history, start-up motives, preparatory periods, and start-up funds to figure out the relationship between sales and operating profits with regression analyses. Regression analyses were conducted based on the foregoing with a view to identifying the effects of start-up preparatory factors on business performance. Results – Since start-up preparatory factors generally affect business performance, it was identified that start-up preparatory factors importantly affect operating profits and sales, which are business performances. However, start-up preparatory periods and the implementation of education among preparatory activities were shown to have no effect on business performances, and the effect of the ratio of start-up fund provided by the founder on operating profits was shown to be not significant. Conclusions – The present study comprehensively examined those start-up preparatory factors that have positive effects on business performances after start-up. The present study is meaningful in that it can provide positive implications for efficient start-up of small enterprises hereafter.
