동물용 고압산소치료 시 산소를 통한 가압은 이미 있는 공기를 제거하고 산소로 대치시키는데 효율성이 떨어져서 100%에 가까운 산소분압을 구현하는데 어려움이 있고, 그 방법도 표준화되지 않았다. 따라서 어떠한 방식의 산소가압이 신속하고 효율적으로 100%에 가까운 산소분압을 구현할 수 있는지에 대한 방안을 개발하고 표준화할 필요가 있다. 동물용 고압산소치료를 활용한 동물실험이나 동물의 치료 중 가압 단계에서 간헐적 환기 방법이 더 신속하게 100%에 가까운 산소 분압을 보이므로 향후 표준 지침 개발을 위한 중요한 기반 연구와 제안으로 활용 가능하다. 이는 재난 기반으로의 고압산소챔버의 활용을 위한 기초 자료가 될 것이다.

The goal of this study is to examine the status quo of industrial-educational cooperation in Technical high schools. Based upon the findings of the current conditions, this study ultimately aims to propose methods through which more active industrial-educational cooperation can be stimulated. The methods chosen for this study are reference research and surveys. The survey was conducted by imposing complete enumeration on the targeted high schools that specialize in industry related fields. The survey targets were the directions of academic affairs, the directions of practical affairs, and the directors of the educational curriculum of each school.The research results are as follows: First, the teachers recognize the necessities of having opportunities to gain specific skills in different industrial fields, having chances to get stable employment, and securing the industrial institution's competitiveness through the customized nurturing and supply of human resources as the primary goals of industrial-educational cooperation. Second, the teachers express the similar opinion that industrial-educational cooperation in their current system is inappropriate to achieve their goals. Third, the teachers claim that an educational curriculum that emphasizes industrial educational cooperation must be developed and managed. Fourth, it was found that when schools plan their educational curriculum, they often do not implement the requests from industrial institutions. Fifth, major educational program implement methods that meet the requests of the industrial institutions include field trips or the introduction of other field-based experience learning programs, the application of customized curriculums based on industrial-educational cooperation, and the invitation of industrial-educational personnel as teachers to school environments. Sixth, it was concluded that educational institutions need to proactively seek companies for cooperation; they need to support, develop, and manage school programs that are based on industrial-educational cooperation; and finally, institutions need to enthusiastically participate in the government's vocational education policies that are founded upon industrial-educational cooperation. Seventh, the enforcement of selective curriculum for the benefit of diversifying the educational program; the pursuit of balancing the specialized curriculum through shedding the national educational level provided within the regular curriculum; and the establishment of related amendments on the national level to provide effective industrial-educational cooperation have been identified as the vital factors that can develop the educational programs within high schools specializing in industry and that are closely related to industrial educational cooperation.

An invention produced through research by a professor at a university is an employee invention, and the industrial academy cooperation foundation of the university has the right to obtain a patent. The professor, in return, obtains the right to receive reasonable compensation for that invention. Research was carried out mostly by the cooperation and participation of students rather than the solitary performance of the professor. The contributory portion of the student to an invention can be treated as an employee invention, but occasionally it is considered a free invention. Therefore, the unilateral succession to the right to obtain a patent to the industrial academy cooperation foundation highlights the potential disputes between the university and students in the future. Therefore, in this study, the intellectual properties management codes of 80 universities were reviewed and analyzed for any possible problems and the appropriate directions to the codes' amendments are suggested.

We studied the influence of Hanwoo (Korean native cattle) manure compost soil application on the growth and yield of maize (Zea mays L.). We compared the soil application of chemical fertilizer (CF), commercial manure (CM), Hanwoo manure (HM), and the mixed Hanwoo manure and chemical fertilizer (HM + CF). CF application showed faster tasseling and silking dates compared to the other treatments. During the early plant growth stage of maize, CF application resulted in taller plant height, However, during later growth stages (55 days after transplanting). HM (226.0 cm) and HM + CF (230.0 cm) treatment resulted in taller plant height compared to CF (216.2 cm). Post-harvest measurement results showed that, the ear length was longer in HM (22.13 cm) and HM + CF (22.70 cm) compared to others, while ear diameter, ear weight, and 100-grains weight showed no significant difference among CF, HM, and HM + CF groups. The use of HM resulted in delayed growth during the early stages of plant development compared to CF. However, crop productivity markers of ear weight and ear diameter showed no significant difference compared to CF. Thus, HM treatment was comparable to CF treatment in maize cultivation.

As the economic, social, and environmental problems of the local community reach a serious level, our society is realizing the need to foster young talents who discover opportunities in local issues through entrepreneurship education and create social values through creative challenges. However, entrepreneurship education programs are generally focused on commerciality, so customized education programs to solve regional problems are insufficient. Therefore, this study aimed to develop a community problem-solving entrepreneurship curriculum. In this study, a competency based curriculum model was applied to develop the curriculum, and regional problem-solving entrepreneurship competencies were derived through expert advice from a total of 10 people. In the process, the Delphi methodology was additionally used to reduce the possibility of errors in the competency model. As a result of the study, a total of 23 regional problem-solving entrepreneurship competencies were confirmed, and knowledge(K) - skill(S) - attitude(A) by competency consisted of 5, 9, and 9, respectively. By applying this to Dunham's problem-solving six-step model, modular learning support measures were developed in the order of phase 1(problem discovery), phase 2(problem analysis), phase 3(plan), phase 4(measure), and phase 5(evaluation). This study is meaningful in that it integrated theory and practice by developing specific entrepreneurship curriculum and learning support measures based on the theoretical model devised in social welfare. In addition, it has implications in that it developed a regional problem-solving entrepreneurship competency model based on expert advice and proposed a specific curriculum based on this.

현대사회가 당면한 다양한 문제를 해결하는 주체로 '제4섹터(the fourth sector)'가 주목받고 있다. 제4섹터는 사회적경제 기업으로 대표되는 제3섹터의 지나친 정부 의존도와 서비스 모델 동형화의 문제점을 해결하고자 등장하였다(Meadows, 1972; Howaldt and Schwarz, 2010). 이러한 제4섹터의 핵심 주체로서 소셜벤처가 언급되고 있다(경기연구원, 2018). 그러나 아직까지 소셜벤처에 대한 학술적 및 정책적 개념이 모호한 실정이다. 따라서 본 연구에서는 사회의 포용적 성장을 도모하기 위해 제4섹터로서의 소셜벤처 정의와 특성을 명확히 하고, 소셜벤처 생태계 활성화를 위한 발전전략을 연구하고자 한다.

최근 딥러닝 기술은 다양한 분야에서 놀라운 성능을 보여주고 있어 많은 서비스에 적용되고 있다. 얼굴인식 또한 딥러닝 기술을 접목하여 높은 수준으로 얼굴인식이 가능해졌다. 하지만 딥러닝 기술은 원본 이미지를 최소한으로 변조시켜 딥러닝 모델의 오인식을 발생시키는 적대적 예제에 취약하다. 이에 따라, 본 논문에서는 딥러닝 기반 얼굴인식 시스템에 대해 적대적 예제를 이용하여 기만공격 실험을 수행하였으며 실제 얼굴에 분장할 수 있는 영역을 고려하여 설정된 변조 영역에 따른 기만공격 성능을 분석한다.
