The defense industry is a future-oriented industry, in which high-tech technologies are concentrated. In addition, it is a key industry for maintaining national security, and the R&D of the defense industry is very important. With the introduction of a competitive system by defense industry companies, the necessity of improving the efficiency and productivity of defense industry companies is emerging. In this study, the efficiency of the defense industry was measured using the CCR and BCC model. In addition, super efficiency was derived using the Super-SBM model. For this study, the 2019 defense industry management analysis data of the Korea Defense Industry Association (KDIA) was used, and the analysis was performed by setting the number of researchers and investments of domestic defense industry companies as the input variables and sales as the output variables. Through this study, it is expected that the defense industry's R&D efficiency will be grasped, which will help establish a policy for fostering the defense industry in the future.

최근 국내에서는 하천변 생태계를 대상으로 생태구조 및 서식처 평가 등 많은 연구가 진행되었음에도 불구하고 생태적 변화를 예측하고 예측된 결과에 따라 생태복원 대책을 수립할 수 있는 연구는 현재까지 미흡하다고 볼 수 있으며, 이는 생태복원 연구에 있어 주요과제라고 할 수 있다. 이에 반해 유럽과 미국에서는 수문학적 서식처 조건에 따른 식생 반응 예측 등 수문생태 모형에 대한 연구가 꾸준히 이루어져 왔으며, 최근에는 습지, 홍수터 등을 대상으로 생태보전 복원분야에 널리 응용되고 있다. 본 연구에서는 국외의 수문생태모형 적용사례를 분석하여 국내 적용가능성 및 문제점에 대한 타당성을 제시하고자 하였다. 그 대상으로는 유역 내에 홍수량 분담을 위한 천변저류지를 적용하였으며, 의미상으로 홍수터(범람원), 습지 역시 해당 범위에 포함할 수 있다. 천변저류지는 홍수기와 비홍수기에 따라 활용 측면을 구분할 수 있으며, 이런 맥락에서 천변저류지의 수위변화는 식생 변화의 중요한 요소(factor)가 될 수 있다. 그 외 범람시기, 범람일수, 건조기간 등을 포함한 수문요소 역시 수문생태 모델의 예측 변수인 식생 성장에 영향을 미치게 된다. 이러한 수문/생태시스템의 상호관계를 활용하고 모형의 형태를 국내 식생에 대한 생리학적 특성에 맞게 변화시킬 수 있다면 국내 천변저류지에도 충분히 적용 가능할 것으로 판단된다. 또한 잠재적으로 식생 성장에 영향을 줄 수 있는 다양한 환경조건 예를 들면 영양물질, 토양구조, 토사 퇴적 등을 적용대상지 환경에 맞게 포함하거나 고려할 수 있다면 모형의 재현성을 더욱 높일 수 있을 것이다.의 기대효과를 가져올 수 있으리라 생각되며 분석된 인자들은 수달 서식지를 위한 하천정비의 기초자료에 유용할 것으로 보인다.따른 유량측정망을 구축하는 것이다.의 의사결정 지원 도구가 될 것이다. 따라서, 본 연구에서는 도시유역의 물순환 해석을 위한 일련의 과정, 즉 자료의 조사 및 취득에서부터 물순환 해석 모형을 이용한 정량적 현황파악, 물순환 개선 기법 및 평가를 수행함에 있어 주요 착안점 및 실무에서의 기술적 가이드를 제공하고자 하였으며, 보다 세밀한 도시유역의 물순환 해석을 위하여 우리나라와 일본에서 적용이 활발한 물리적 기반의 분포형 모형(WEP, SHER, SWMM)의 적용사례를 통하여 국내 도시하천의 물순환 해석에 활용함에 있어서의 실질적인 적용절차 등을 제시하고자 하였다. 한다.호강유역의 급격한 수질개선을 알 수 있다.世宗實錄) $\ulcorner$지리지$\lrcorner$(地理志)와 동년대에 동일한 목적으로 찬술되었음을 알 수 있다. $\ulcorner$경상도실록지리지$\lrcorner$(慶尙道實錄地理志)에는 $\ulcorner$세종실록$\lrcorner$(世宗實錄) $\ulcorner$지리지$\lrcorner$(地理志)와의 비교를 해보면 상 중 하품의 통합 9개소가 삭제되어 있고, $\ulcorner$동국여지승람$\lrcorner$(東國與地勝覽) 에서는 자기소와 도기소의 위치가 완전히 삭제되어 있다.

Since the late 20th century, due to the globalization of markets and the rapid developments of information and communication technologies, the world has entered into the age of fierce competition. With their abundant low-cost labor, former communist countries such as China, Russia and East Europe and former low-developed countries such as India and Brazil have received foreign investments from major industrial companies. Thus, there are no other alternatives remained for Korea and OECD countries other than moving the industrial economies to the knowledge based innovation systems. In the knowledge based innovation systems, economic developments and employments of regions and nations depend solely on companies situated in their territories. In this article, after reviewing the current state of technological based innovation small firms in korea, we provide a theoretical framework to promote the level of technology based innovation and entrepreneurship. The theoretical framework for analysis and policy suggestions is based on the Schumpeter's value system model that consist of supply factors, demand factors, and supporting institutions. In order to create more innovative small businesses, we insist on the followings. First, more R&D and innovation activities related with promising new technologies should be performed. Second, more R&D funds for technological innovation small companies should be provided from governments. Third, more M&A transactions and technology transactions should be marketed freely and competitively. Fourth, more business incubating services and venture capital services should be provided. Fifth, entrepreneurship and innovation culture should be popular and institutionized among people.

The damage of cyber bullying is increasing. A response of code is needed with that of law and education. This study would use the strengths of a virtual simulation as one of the technical solutions. Students learn cyber bullying and prevention of it through each step. The steps in this application model consist of recognition${\rightarrow}$judgement${\rightarrow}$decision${\rightarrow}$behavior. Each detailed step of this model is made of pre-briefing${\rightarrow}$demanding of response${\rightarrow}$participating in response${\rightarrow}$result and feedback${\rightarrow}$growth${\rightarrow}$debriefing. Thus we developed the application model of this virtual simulation and implemented it for education and prevention of cyber bullying. We hope that the model and simulation developed by this study would reduce the damage resulting from cyber bullying.

With the advent of the WTO system in 1995, non-tariff barriers including technical barriers to trade(TBT) has become one of the important issues in world trade order. The purpose of this study is to analyse an impact of the calibration and measurement capabilities(CMC), the degree of equivalence of national measurement standards which is maintained by NMIs to provide governments with a technical foundation for wider agreements related to international trade. The results of the analysis using the gravity model with the proxy of the CMC shows that the CMC has a positive impact on Korean trade. Particularly, it was estimated that the CMC registered by high-income economies has more impact on Korean trade than those by low income economies. This implies that the countries highly dependent upon foreign trade like Korea need to have much more interest in the investment into measurement standards and science which is generally considered to be a public goods.

To respond the climate change and environmental pollution, the studies on renewable energy policies are increasing. The renewable energy is a new growth engine technology represented by the green industry and green technology. At present, the investments for the renewable energy supply and technology development projects of three main strategy sectors such as sunlight, wind power and hydrogen fuel cell are implemented in our country, while they are still in the early stage, accordingly reducing those uncertainty for the research direction and investment fields is the most urgent issue among others. Thus, this study applied text mining method and multinominal topic model among the big data analysis methods on our country's newspaper articles concerning the renewable energy over the last 10 years, and then analyzed the core issues and global research trend, forecasting the renewable energy fields with the growth potential. It is predicted that these results of the study based on information and communication technology will be actively applied on the renewable energy fields.

Environmental changes, which are strongly requiring technological cooperation, such as technological development and strategic alliances according to industrial ecosystem change, have a significant impact on not only product quality but also services. Thus, there is a need for 'servitization' that can satisfy the needs of customers and the ecosystem of businesses through the convergence of manufacturing companies and services. This study uses the Expectation-Confirmation Model to examine the impact on user satisfaction and Continuance Usage Intention. Research(Study) was conducted on users who are using high-tech-based cars. For this, we used Expectation Confirmation(match expections for the user's pre-and post-use relationships), Perceived Ease, Perceived Usefulness, User Satisfaction and Habitual Use and using Continuance Usage Intention as a dependent variable. Their causation was examined with the spss 26.0 and smartpls 2.0 statistical programs. As implications of this study, Expectation Confirmation has been shown to have significant positive effects on Perceived Ease, Perceived Usefulness, User Satisfaction and Habitual Use. For this results, the expectations before and after the use of high-tech cars lead to improved daily lives convenience and(or) work efficiency, leading to user satisfaction and further Continuance Usage Intention. Motors consider it important to pursue the work improvements that consumers want and use it useful in daily lives in the production and sale of high-tech cars. It is expected that it will create natural habits for services that users are satisfied with, and that these habits will affect the continuous growth and understanding of the trend of change.

Hydrogen energy is emphasized as a substitutable energy of carbon-based energy system in the future, since it is non-depletable and clean energy. Long term vision of Korean government on the national energy system is to promote hydrogen energy by 15% of final energy demand until 2040. This study analyzes economic impacts of hydrogen energy development employing a dynamic CGE model for Korea. Frontier technology such as hydrogen energy is featured as slow diffusion at the initial stage due to the learning effect and energy complementarity. Without government intervention, hydrogen energy would be produced upto 6.5% of final energy demand until 2040. However, if government subsidizes sales price of hydrogen energy by 10%, 20%, and 30%, share of hydrogen energy would increase 9.2%, 15.2%, and 37.7% of final energy demand. This result shows that the slow diffusion problem of hydrogen energy as frontier technology could be figured out by market incentive policy. On the other hand, production levels of transportation sector would increase while growth rate of oil and electricity sectors would decline. Household consumption would be affected negatively since increase of consumption due to the price decrease would be overwhelmed by income reduction owing to the increase of tax. Overall, GDP would not decrease or increase significantly since total production, investment, and export would increase even if household consumption declines.
