최근 기후변화와 기상이변으로 예측하지 못한 게릴라성의 국지성호우로 인해서 과거 장마와 같은 피해가 아닌 변화된 강우패턴으로 막대한 피해가 나타나고 있다. 또한, 이러한 게릴라성 호우는 예측 또한 어려운 경향을 나타낸다. 이러한 피해를 방지하기 위해 단기유출 예측을 위해 사용되는 다양한 모형들 가운데 GRM(Grid based Rainfall-runoff Model)을 사용하였으며, GRM모델은 단기유출해석에 사용되며 국내에서 개발된 물리적 기반 모형이다. 본 연구에서는 한강의 하류인 청미천 유역을 대상으로 강우-유출 분석을 진행하였으며, 환경부의 11개 기상관측소의 자료를 이용한 티센망도 기반의 면적강우량으로 산정하였고 이를 GRM에 적용하였다. 강우자료의 Event 선정기간은 2011년 6월 29일부터 2011년 7월 1일까지 86.83mm 강수가 내린 Event이다. 공간자료는 국토지리정보원의 90M DEM(Digital Elevation Model), 농촌진흥청의 정밀토양도와 토심, 환경부 환경공간서비스의 대분류 토지이용도를 이용하였다. 또한, 검정을 위해서 정형우도인 NSE, 비정형우도인 Log-normal 우도를 이용하여 분석하였으며, 각각의 결과값은 NSE 0.966, Log-normal은 -1214.97의 값을 나타냈다. 추후, 다양한 적합지표를 이용하여 GRM의 강우패턴별, 유역별대표매개수가 산정된다면 홍수방어를 위한 강우-유출 모형으로 매우 유용하게 활용될 것으로 판단된다.

In order to cultivate human resources to live in the 4th industrial revolution era, software (SW) education became mandatory in the 2015 revised curriculum. Furthermore the science mathematics informatics education promotion law was enacted to emphasize the importance of software convergence education. Therefore, it is necessary to study how to converge and educate mathematics and science with software education to solve problems in real life and various disciplines. This study is to find the directions and effectiveness of software convergence education through content analysis of the software mathematics science convergence teaching and learning materials, which are recently developed and distributed by the Ministry of Education et al. The results of this research are expected to suggest implications to future researches about software, mathematics and science convergence education.

Customers who visit nail shops need creative and unique designs, but at present nail artists remain at the level of design imitation, new nail art designs should be developed to satisfy customers. Therefore, this study presented convergent nail art designs using formative art principles which are the basis of all design with the aim of contributing to creative nail art designs. For this purpose, this study investigated specialized books, Internet data and previous studies on the subject, analysed concepts and cases of formative art principles, and the concept of nail art and related expressive techniques to create six convergent nail art designs. As nail art techniques, this study used hand painting, marbling, see-through, etching, embossing, patching and objet. As a result, this study presented unique and creative nail art designs using formative art principles and found the possibility of creating new nail art designs. This study has meaning in that the results of this study are significant as basic data to enhance the design capabilities of nail artists.

In this study, an approach of image fusion in decision level has been proposed for unsupervised image classification using the images acquired from multiple sensors with different characteristics. The proposed method applies separately for each sensor the unsupervised image classification scheme based on spatial region growing segmentation, which makes use of hierarchical clustering, and computes iteratively the maximum likelihood estimates of fuzzy class vectors for the segmented regions by EM(expected maximization) algorithm. The fuzzy class vector is considered as an indicator vector whose elements represent the probabilities that the region belongs to the classes existed. Then, it combines the classification results of each sensor using the fuzzy class vectors. This approach does not require such a high precision in spatial coregistration between the images of different sensors as the image fusion scheme of pixel level does. In this study, the proposed method has been applied to multispectral SPOT and AIRSAR data observed over north-eastern area of Jeollabuk-do, and the experimental results show that it provides more correct information for the classification than the scheme using an augmented vector technique, which is the most conventional approach of image fusion in pixel level.

This study examined the concept and characteristics of grotesque painting and its history and presented body painting convergence designs using paintings of each age as basic data on creative and unique body painting design. For the purpose, this study theoretically examined the concepts, characteristics and expressing techniques of grotesque and body painting, analysed images of grotesque paintings in each age and represented convergence body painting based on the results. As a result, it was discovered that paintings including grotesque paintings provided infinite imagination and diverse themes for body painting artists. It means that artistic works can work efficiently for future body painting design. Also, it is expected that they will inspire those who want to study them more academically and in an organized way and body painting will have an independent area in art.

In this paper, the needs and environment of the 'AI Convergence Education Method' were analyzed for elementary and secondary teachers, and based on this, teaching efficacy of informatics education was verified. For the research, elementary and secondary teachers who take the subject were selected, and based on the results of analyzing the general characteristics, pre-knowledge level, and needs of the subject, curriculum for 15 weeks was developed. As a result of verifying the teaching efficacy effectiveness of the developed 'AI Convergence Education Method' subject for 15 weeks, the effectiveness of the information education teaching efficacy was verified. Among the factors, there were statistically significant differences in information teaching values and information teaching strategies. In the future, it is necessary to conduct follow-up research to secure teachers' professionalism, such as linking with schools and convergence with other subjects. Various teaching and learning materials and teaching and learning methods such as educational contents and materials, reference literature, and artificial intelligence education platforms need to be prepared.

This study selected college students in Anhui Province as the research subjects and used a questionnaire survey method to understand the current implementation status of the integration of innovation and entrepreneurship education and professional education. The survey results indicate that college students have insufficient awareness of innovation and entrepreneurship; Poor integration of curriculum construction. This study analyzes the reasons for the problems from four aspects: the government, enterprises, and universities, as well as the subjective will of students. Based on qualitative and quantitative research, the following countermeasures and suggestions are proposed: firstly, strengthen top-level design; Secondly, promote the integration of curriculum construction; Thirdly, expand the teaching staff; Fourthly, a practical platform for school enterprise co creation; Fifth, cultivate students' innovative awareness and guide innovative practice.

최근 다양한 산업 군에서 ICT 융합 서비스가 활발히 개발되고 있고 사물인터넷(IoT: Internet of Things) 기술이 신성장 동력의 핵심 기술로 주목받고 있다. IoT는 기존에 연결을 고려하지 않았던 생활 속 모든 것들을(daily life objects) 상호 연결시켜주는 기술이다. 가트너는 현재 1% 미만의 사물만이 인터넷에 연결된 상황으로 보고하고 있고 Cisco의 자료에 따르면 2020년에는 연결된 장치 수가 500억 개 이상으로 증가할 것으로 예측하고 있다. 많은 장치가 연결되는 IoT 환경에는 많은 취약점과 보안 위협이 존재할 것이므로 보안과 개인정보 보호 기술은 반드시 제공되어야 하는 핵심기술이다. 본고에서는 IoT 기반 융합 서비스에서 발생했던 침해 사례를 살펴보고, 안전한 서비스 개발을 위한 기본적인 보안 요구사항을 제시한다.
