인구의 증가와 경제의 발전으로 인해 한정된 수자원에 대한 수요가 급증하였고 향후 고도의 복지사회 구현과 지방 자치화에 따른 각종 용수 수요에 대한 심각한 물 배분 문제가 대두되고 있다. 특히 심각하게 물 배분 문제가 야기될 때 각 수요지점별로 필요한 용수를 공급하기 위해서 단지 상류에서 하류 단으로 물을 배분한다면 수리권의 공정성 문제가 제기되며 물 관리 원칙의 결여에 따른 곤란한 상황이 발생할 수 있다. 이렇게 갈수 및 가뭄 시와 같이 물 배분 문제가 생길시 에는 우선 하천유역 전체의 가용수량을 파악한 후 각 용수 사용별로 중요성을 감안하여 용수공급 우선순위를 설정하여 전 하천 유역을 통하여 일관된 배분을 실시할 수 있는 수자원 최적화 배분 시스템을 개발 할 필요성이 있다. 이러한 문제를 해결하기 위하여 본 연구에서는 한국수자원공사 수자원연구원과 콜로라도주립대학에서 공동 개발한 유역 네트워크 유량 모델(River Basin Network Flow Model)인 K-MODSIM을 이용하여 유역통합 실시간 일 저수지 운영 모델을 개발하였다. 개발된 유역통합 실시간 일운영 모델은 금강유역에 적용하였으며, 금강유역을 12개의 소유역으로 구분하고, 용담댐과 대청댐을 포함하며, 유역관리는 용수공급, 치수대책, 발전수력 및 하천 유지용수의 공급등의 유역내 수자원 관리 상황을 포함하였다. 이처럼 유역의 매우 자세한 세부사항을 고려함으로서 기존에 개발된 모델이 가지고 있던 단순화의 단점을 보완하고 유역의 특성을 최대한 반영하도록 하였다. 또한 유역통합 실시간 일운영 모델의 장기적인 저수지 운영 문제를 해결하기 위해 암시적 추계학적 동적계획법을 사용하여 도출된 월운영룰을 일운영모델에 적용할 수 있는 방법을 제시 하였다.기능으로 구성되어 있으며, 각 기능을 선택하면 해당 화면으로 GUI가 전환된다. 따라서 다량의 측정자료의 신뢰성을 유지하고 이를 모형의 입력자료로 활용하는 일련의 과정을 시스템화하기 때문에 자료의 이상적 유지 관리가 이루어지며 복잡한 2차원 수질해석 모형을 수월하게 운영할 수 있는 시스템으로 개발하였다.제외하면, 부자측정 방법에 의한 유량산정시 가장 큰 오차원인은 홍수시 측정된 유속측선의 위치와 홍수 전후로 측정된 횡단면상의 위치가 일치하지 않는 점과, 대부분 두 측정 구간의 평균값을 대푯값으로 사용한다는 점이다. 본 연구는 다년간의 유량 측정 및 검증 경험과 자료를 토대로 현장에서 부자를 이용하여 측정된 측정성과를 정확도 높은 유량자료로 산정하는데 있어서의 문제점을 도출하고, 이로 인해 발생하는 오차를 추정하여 그 개선방안을 제시해 보고자한다. 더불어 보다 정확한 유량 산정을 위한 기준과 범주를 제시하고자 한다.리적 특성을 잘 반영하며, 도시지역의 복잡한 배수시스템 해석모형과 지표범람 모형을 통합한 모형 개발로 인해 더욱 정교한 도시지역에서의 홍수 범람 해석을 실시할 수 있을 것으로 판단된다. 본 모형의 개발로 침수상황의 시간별 진행과정을 분석함으로써 도시홍수에 대한 침수위험 지점 파악 및 주민대피지도 구축 등에 활용될 수 있을 것으로 판단된다. 있을 것으로 판단되었다.4일간의 기상변화가 자발성 기흉 발생에 영향을 미친다고 추론할 수 있었다. 향후 본 연구에서 추론된 기상변화와 기흉 발생과의 인과관계를 확인하고 좀 더 구체화하기 위한 연구가 필요할 것이다.게 이루어질 수 있을 것으로 기대된다.는 초과수익률이 상승하지만, 이후로는 감소하므로, 반전거래전략을 활용하는 경우 주식투자기간은 24개월이하의 중단기가 적합함을

A variety of creative convergence education studies have been conducted around the world, but the study of creative convergence education based on problem-oriented learning is insignificant. STEAM education development research for engineering human resources also recognizes important factors like ethics awareness and consideration, cooperation, leadership, and communication skills. This study developed a model of interdisciplinary classes between marketing and commercial English classes as a way to effectively learn to cultivate the creative and fusion talents required by modern society. A model was developed for the process of convergence classes to be developed for evaluation after class by designing courses, selecting subjects, designing classes, drawing questions, and developing problems, as well as for discussion of pre-convergence courses, class performance, and class evaluation. The Mongolian university discussed in this paper plans to introduce a suitable educational environment by developing a problem for interdisciplinary classes in marketing and business English. Based on the need to nurture talent required by the rapidly changing knowledge-based society, Mongolian universities should continue the strategy of fostering creative convergence talent through the convergence of technology. This is because creativity is the most important thing in the current situation.

The purpose of this paper is to propose a new security orchestration service model by combining various security solutions that have been introduced and operated individually as a basis for cyber security framework. At present, in order to respond to various and intelligent cyber attacks, various single security devices and SIEM and AI solutions that integrate and manage them have been built. In addition, a cyber security framework and a security control center were opened for systematic prevention and response. However, due to the document-oriented cybersecurity framework and limited security personnel, the reality is that it is difficult to escape from the control form of fragmentary infringement response of important detection events of TMS / IPS. To improve these problems, based on the model of this paper, select the targets to be protected through work characteristics and vulnerable asset identification, and then collect logs with SIEM. Based on asset information, we established proactive methods and three detection strategies through threat information. AI and SIEM are used to quickly determine whether an attack has occurred, and an automatic blocking function is linked to the firewall and IPS. In addition, through the automatic learning of TMS / IPS detection events through machine learning supervised learning, we improved the efficiency of control work and established a threat hunting work system centered on big data analysis through machine learning unsupervised learning results.

Korea's social cooperatives were enacted by law in December 2012. However, it is in the process of being settled and has not been established institutionally. So social cooperatives are failing. The purpose of this study is to reduce these failures. To this end, this study distinguished between co-operatives and social co-operatives. Also, the characteristics and concepts were identified. That is why we want to help our social cooperatives in Korea. The results based on the literature research are as follows. First, in order for domestic social co-operatives to be sustainable, the seven principles of co-operatives must be observed. In particular, the sixth principle is important. It is important to form a social cooperative association and to communicate with local cooperatives. Their communication is less likely to fail because they can share management support information, education, promotion, and strategies. Second, there is a need for a plan that can be applied not only to the government but also to general enterprises in order to support social co-operatives. Third, related policies of the government and the private sector should be designed and managed in an integrated manner to promote social cooperatives. Fourth, public relations should be promoted through campaigns to inform the public that the meaning of social cooperatives is for the public good. In addition, the government needs to build a program that fosters professionals who can foster social co-operatives. In conclusion, it is meaningful that this study suggests possible ways to develop social co-operatives in Korea, and provides support to the Korean government.

This study is to search the problems of schoolyard teaching material developed by pre-service earth science teachers and the critical factors affecting material making. The 258 schoolyard teaching materials was collected from 54 pre-service earth science teachers (male: 18, female: 36) major in Earth Science Education in Jeonju, Korea. The schoolyard teaching materials was greatly influenced by making process type of it and the prior knowledge of pre-service earth science teachers. As schoolyard preference exploratory type rely on their prior knowledge to develop the schoolyard teaching materials, they made use of the limited concepts like fault in material making. But the concept preference exploratory type made use of concepts not accessible to majority of pre-service earth science teachers because they selected a concept from the earth science textbook first of all. The pre-service earth science teachers having wrong prior knowledge selected inappropriate resources, as well as fell into the error of concept connecting. The pre-service earth science teachers having right prior knowledge partly considered only shape of resources, but had a disregard for formation process of it in material making. Accordingly, we need to reflect richly Geological Field Trip and Solid Earth Science to curriculum for earth science teacher education. And we have to educate pre-service earth science teachers to create holistic concept on the geological subject matter knowledge, field based teaching and learning strategy, material making process.

The purpose of this study is to analyze the characteristics of the media contained in textbooks for students with disabilities based on the information processing model, and to find ways to utilize library materials for class improvement for them. To this end, the media included in the in-depth learning activities of the Korean language textbooks of the 2015 revised special education basic curriculum were analyzed. As a result of the analysis, it was found that students with disabilities received information mainly through vision, process information through understanding, and use language intelligence to produce results. Specifically, they accepts learning contents through illustrations and texts, processes the contents based on understanding such as reasoning and explanation, and then uses linguistic intelligence such as writing and speaking to produce results. Based on the results of this analysis, a practical method to utilize library materials in the Korean language class of students with disabilities was proposed as follows. Developing a variety of input mediums based on reading stages and collection mapping for students with disabilities. Providing book materials through reading and listening. Teaching appropriate methodological knowledge to self-directly solve advanced learning activities. In addition, developing types of writing and writing strategies that can help various production activities.

In recent years, synthetic and systematic management with conservation-oriented strategy for Baekdu-daegan, which is the greatest chine as well as the major ecological axis of the Korean Peninsula, is being required to cope adequately with the various kinds of developmental urge. For this, spatially definite zoning for the managerial area on Baekdu-daegan has to be completed first. This study is to take into consideration the traditional concepts of stream and watershed as well as the actual disturbance on Daegan area, and to propose the process for reasonably establishing the managerial boundary adjacent to the Ridges. The case site with topographically diverse characteristics was selected, and the analyses on watershed, road network and land use were carried out using the digital maps and Landsat TM images. Based on these analyses results, the managerial boundaries as alternatives from the Ridges were produced by watershed expansion process, and used for tracing the changes of road occupancy rate and the areal ratio of various land use types to the relevant watersheds to search out the adequate managerial boundary. The results show that watershed expansion process could be effective tool for establishing the managerial boundary, and the fourth expanded watershed would be included for the adequate managerial boundary of the case site.

This study was conducted to identify the influence of nursing image and nursing as a major, on the professionalism of male nursing students. Totally, 180 male nursing students having experience in clinical practice from B and U cities, were enrolled as subjects. Data were collected from 15th November to 15th December, 2016. Analysis by t-test, ANOVA & Scheff's test, Pearson's correlation coefficients, and stepwise multiple regression revealed a mean score of nursing image at 3.95, major satisfaction score of 3.90, and nursing professionalism score of 3.79. The degree of professional awareness amongst the participants was statistically and significantly different, depending on their year of study and the person who had recommended nursing as a career option. Nursing professionalism was highly correlated with the nursing image, and moderately correlated with satisfaction of nursing as a major subject. Results also indicated that 60.6% results indicating nursing professionalism were most significantly influenced by two factors: the image of the nurse, followed by satisfaction of nursing as major. We conclude that to improve the nursing professionalism of male students requires education and strategy to improve their nursing image, and career education and guidance that focuses towards greater satisfaction for their selected major subject.
