Entrepreneurship of a founder and psychological characteristics are very important factors for the start-up success. To understand the importance like this, this study investigated effect relationships of the entrepreneurship and psychological characteristics on the start-up success. For this, 122 copies of the questionnaire were empirically analyzed for the youth entrepreneurs who entered the youth founder academy which is founded and managed by the Small and Medium Business Corporation. According to results of analysis, both the entrepreneurship consisting of proactivenss, risk taking and autonomy, and the internal locus of control, the psychological characteristics were found to have positive effects on the start-up success. Therefore, this study suggested theoretical and practical implications, as below, according to the results. Firstly, we must be aware of the importance of the entrepreneurship from the perspective of a successful establishment, and, prospective entrepreneurs, who are planning to the start-up, have to judge their entrepreneurship and, only then, make a decision. Secondly, we have to put our best efforts into developing more effective education on start-up, which deals with improving youth founder's entrepreneurship. Therefore, education institutions for start-up are needed in order to develop educational programs such as "Entrepreneurship Training Programs". Thirdly, we must recognize that the role of family is important because most entrepreneurship and psychological characteristics are formed in a person's childhood. Forth, the entrepreneur, themselves, must realize that they has to make an effort to improve their entrepreneurship. Lastly, youth founder's internal locus of control has to be enhanced. Thus, greater attention is required from both the entrepreneur themselves, and educational institutions for start-up.

Traditionally, foreign labor inflow into Korea has been rare and, hence, issues on foreign workers did not draw much attention. However, changing economic conditions of the Korean economy, such as "labor-shortage" problem in SMEs in manufacturing sector, has made the Korean government open its door to the foreign workers since the early 1990s through the Industrial Trainee System. The inflow of foreign workers, on the other hand, has generated various social and economic problems, such as substantial increase of illegal over-stayers, illegal utilization of foreign unskilled workers by domestic SMEs, to name a few. Against this background, the Employment Permit System was implemented from 2004. This new system aims at supplying foreign workers to SMEs as well as protecting them as legal 'employees'. In any case, it is very important to understand how and to what extent the inflow of foreign workers have affected the Korean economy in order to establish long-term policy stance. This paper aims to empirically assess the economic impact of foreign workers on domestic workers in the manufacturing sector during 1997~20001, focusing on the Industrial Trainee System. The empirical results of the paper can be summarized as follows. First, there is some evidence that male semi-skilled workers are the group that is likely to have been displaced by industrial trainees. Second, we were unable to find any strong evidence suggesting that the inflow of foreign industrial trainees decreased wages of less-skilled Korean workers.

The purpose of this study is to find out whether critical thinking education improves critical thinking disposition of nursing college students. The participants were 173 second graders. The education was conducted three times, two hours each, for a total of six hours of intensive critical thinking education and continuous education during Nursing Process class. The survey was conducted in the first week and 14th week of the course. The collected data was analyzed with IBM SPSS 21.0. Findings: The results showed that the average rating of critical thinking before and after education was raised(3.65±0.41→3.83±0.46, t=6.796, p<.001). Among the sub-items, creativity, which had the lowest score before education, has been raised the most(3.13±0.78→3.43±0.86, t = 5.842, p<.001). The effectiveness of critical thinking education has been confirmed. But it is a lack of evidence on the relevance of the details. It is suggested that repeated research is needed to ensure the quality of education, develop teaching methods, and develop tools for verifying effectiveness.

국내뿐만 아니라 세계적으로도 산사태 발생에 따른 토석류 피해가 빈번하게 발생하고 있으나 아직 토석류 거동에 대한 물리적인 특성을 규명하고, 실험 등을 통한 면밀한 검토가 안 되었다. 토석류는 집중호우 시 토사 내 함수량의 증가로 인해 또는 지진, 화산 발생 시 지각 변동으로 인해 사면의 저항력이 약화되어 발생한다. 이러한 토석류는 재해를 일으키는 매우 위험한 자연 현상이며, 그 규모에 따라 하류부에 큰 피해를 발생시킬 수 있다. 국내에서 수행된 토석류 관련 연구들은 해외에서 주로 수행된 기초연구 결과를 이용한 토석류 피해 발생예측, 위험지도 작성, 토석류 방지 구조물 개발 등의 응용연구가 대부분이며 소규모 모형을 제작하여 수리실험이 진행되었다. 김기환 외(2008)은 토석류 확산형태와 흐름 속도에 대한 모형실험을 수행하였으며, 김영일과 백중철(2011)은 토석류 유동과 퇴적 특성에 대한 실험을 수행하였다. 미국의 경우 미지질조사국(USGS, U.S Geological Survey)에서 1994년부터 지금까지 100 m 길이의 대형 경사수로를 이용하여 토석류 수리모형실험을 수행하고 있으며 이를 통해 토석류의 수위, 충격력, 전파속도, 유출 후 퇴적형상 등에 대한 다양한 실험데이터를 제시하고 있다. 그러나, 현재까지 국내외 토석류 실험에 대한 표준실험방법과 기준이 정립되지 않아 실험결과의 신뢰성을 명확히 증명하기 어려운 실정이다. 토석류로 인한 가장 직접적인 피해 인자인 토석류의 충격력과 전파속도를 수리모형실험을 통해 정량적으로 파악하기 위한 시험 표준으로 시험 절차, 시험 방법 및 적정한 측정장비의 사양 등을 단체표준을 통해 제공함으로써 시험의 불확실성을 최소화하고, 명확한 프로세스에 따른 시험 결과의 신뢰성과 일관성을 확보하고자 한다. 국토교통연구인프라운영원에서는 단체표준 개발을 위한 시험기관협의체를 구성하고, 이해관계인들의 의견을 반영한 토석류 충격력과 전파속도 측정방법(안)을 2022년에 7월 작성하였으며, 현재 이해관계자들의 의견을 수렴하고 중소기업중앙회에 심의를 상정한 상태이다.

The machinery industry provides infrastructure to many manufacturing industries and it has strong influences on performance and quality of products. However, Korean economic growth has been constantly causing the korean general machinery industry to significantly depend on Japan. To solve this problem, many industrial policies have been tried. In this paper, we divide the value chain of general machinery industry into four steps; technology development step, manufacturing step, marketing step, and after-sales management step. We study the relationships between each of these steps and the awareness of dependency on Japan. For empirical analysis we surveyed 207 domestic companies in general machinery industry. The findings are that the three factors, technology development competency, marketing competency and after-sales management competency have significant relationships with dependence on Japan. Manufacturing competency is not a significant factor. As control variables, the type of manufacturers has effect on dependency on Japan. The company size, the kinds of products and technology levels of products don't have effects on the relationship between the four steps of the value chain and dependency on Japan. To overcome the trade imbalance with Japan in the general machinery industry, we recommend to develop technology development competency, marketing competency, and after-sale management competency. Also we need to adopt industry supporting policies, not depending on all three control variables of company sizes, the kinds of products and the technology levels of products, but depending on the type of manufacturers.

It is not surprising to hear news about irresistible natural disasters all over the world due to climate change. Korean Government has focused on developing a variety of green technologies to reduce green house gasses, in particular, carbon dioxide. This study suggested 18 technology divisions for achieving green highway technology development in six different sub-sectors considering life-cycle of roadway and surveyed 29 highway and/or transportation professionals of three institutes using AHP(Analytical Hierarchy Process) analysis to construct "Green Highway"and realize carbon emission reductions and energy use efficiency in a road sector in Korea. Expert Choice Software was used to rank 18 technology divisions weighted by two-level choices. Transport Operating Infrastructure Improvement, Roadway Policy Implementation, Green Transportation(such as Pedestrian and Bicycle) were highly ranked by respondents according to results of the AHP modeling. Among the 18 divisions, technology policy for supporting R&D investments from development to commercialization was ranked as the most significant one to be focused. Green Transportation Facility Design/Construction/Operation and Eco-Friendly Roadway Plan were followed as expected since professionals have thought that the planning/design step of the life-cycle is a starting point to reduce carbon dioxide from roads more and more. Additionally, comparing the results with the Government investment trend 2006-2011 for the roads, it can be interpreted that the Government should invest to the R&D area more widely than before to promote element and core technology development for Green Highway Construction. Above all, small and mid-sized businesses have to be invested as well as encouraged to undertake green highwayrelated objects to accomplish the divisions which ranked high.

Recently, as the roles and utilization fields of UAV become more diverse, demand for high - level mission has been increasing. To solve this issue, researches on the operation of multiple small UAVs and related systems have been actively carried out. The multiple small UAVs based application system has a problem that the task complexity of control personnel increases because the control personnel must continuously control and manage several small UAVs. Hence, it is necessary to develop a software platform that can perform efficient control in order to employ a multiple small UAVs based application system successfully. In this paper, we propose an effective ground control software platform for application systems using multiple small UAVs. We first analyze the requirements for the software platform, and design and implement software based on the analysis. Simulation using the X-plane flight simulator shows that multiple flight data are effectively displayed and that the image data transmitted from many small UAVs are simultaneously displayed in real time.
