The public records of universities shall be classified according to the Enforcement Decree of the Public Records Act and public records management activities shall be carried out accordingly. Among various kinds of public records of the university, the records of performance management are still managed as paper documents, such as attendance books, answer sheets, and assignments, and the management system and methods of each school are different, making it difficult for the management manager to manage them. In this paper, we propose a service model that can perform blockchain-based records management of records related to performance at universities currently kept in paper documents. The proposed service is expected to reduce resource consumption, such as the cost, time and effort spent on storing and managing paper documents.

The purpose of this study is to analyze the influence of number of targets on common knowledge generation and brain activity during the common life science discovery task performance. In this study, 35 preliminary life science teachers participated. This study was intentionally made a block designed for EEG recording. EEGs were collected while subjects were performing common discovery tasks. The sLORETA method and the relative power spectrum analysis method were used to analyze the brain activity difference and the role of activated cortical and subcortical regions according to the degree of difficulty of common discovery task. As a result of the study, in the case of the Theta wave, the activity of the Theta wave was significantly decreased in the frontal lobe and increased in the occipital lobe when the difficult difficulty task was compared with the easy difficulty task. In the case of Alpha wave, the activity of Alpha decreased significantly in the frontal lobe when performing difficult task with difficulty. Beta wave activity decreased significantly in the frontal lobe, parietal lobe, and occipital lobe when performing difficult task. Finally, in the case of Gamma wave, activity of Gamma wave decreased in the frontal lobe and activity increased in the parietal lobe and temporal lobe when performing the difficult difficulty task compared to the task of easy difficulty. The level of difficulty of the commonality discovery task is determined by the cingulate gyrus, the cuneus, the lingual gyrus, the posterior cingulate, the precuneus, and the sub-gyral where it was shown to have an impact. Therefore, the difficulty of the commonality discovery task is the process of integrating the visual information extracted from the image and the location information, comparing the attributes of the objects, selecting the necessary information, visual work memory process of the selected information. It can be said to affect the process of perception.

Housing issues such as mushrooming slums remain as chronic in most developing countries. Due to the state's restrained capacity, the housing-vulnerable's self-help approaches have been increasingly inevitable and vital for addressing the housing issues. However, there are still two challenges: securing good quality with economic efficiency, and climate change mitigation and adaptation. This study aims at doing an architectural experiment by developing and educating the production of eco-friendly interlocking stabilized soil bricks (ISSB) by employing vernacular materials and technologies for housing-vulnerable communities in Indonesia. In collaboration with a local architectural NGO, the study features a co-creation workshop in which 40 evicted households participate in the whole process. Soil analysis, mixed design, compression tests, and economic analysis are carried out. This paper illustrates that ISSB also has a high potential as an alternative to a burned brick or a cement block. The application of ISSB to self-help housing is expected to have socioeconomic and environmental effects, thereby facilitating the housing-vulnerable's self-help approaches and contributing to addressing the housing challenges in Indonesia.

It is changing to the 4^th Industrial Revolution rapidly as the information age through the Internet is changing, and it is rapidly changing to the era of the IoT using all things. In education, with the change to the Internet of Things, interest in education for the 4th Industrial Revolution is increasing. It is necessary to change from NetPBL method using Internet to T-PBL using Triz. In this paper, we focus on the task-based learning (T-PBL) method using Triz and examine the necessity and importance of its use. We propose a teaching model using Triz as a tool for T-PBL. Triz is being used as a tool to solve problems in creative ways. We will design a model applying Triz to the blockchain system security class related to the IoT.

동영상에서 움직이는 객체 검출은 동영상의 내용을 표현하고 유사한 동영상을 검색하는 데 있어 중요한 특징간을 추출하는 방법으로 사용된다. 그러나 복잡하게 카메라가 움직이는 동영상에서 움직이는 객체 검출은 아직까지 어려운 과제이다. 본 논문에서는 복잡한 카메라의 움직임이 있는 환경에서 움직이는 객체를 강인하게 검출하는 방법을 제안한다. 움직이는 객체 검출 방법은 입력 영상을 색상간의 클러스터링을 이용하여 각 영역으로 구분하는 Mean Shift 알고리즘과 인접한 프레임에서 구분된 영역을 대응시켜 영역의 모션 벡터를 구하는 영역 매칭, 유사한 궤적을 가지는 영역들의 클러스터링을 이용하여 객체를 검출하는 궤적 클러스터링 알고리즘을 사용한다. 제안한 영역 기반 알고리즘은 기존의 픽셀이나 블록 기반의 방법보다 움직이는 객체를 정확하게 검출하였다. 실험 결과 복잡하게 움직이는 카메라의 환경 속에서 움직이는 객체를 강인하게 검출하였다.

최근 세계는 경제블록화가 급속한 진행되는 한편 EU가입국의 확대, 중국의 WTO 가입을 비롯하여 정보통신기술의 발달에 따른 무역 패러다임의 변화 등으로 급격한 전환기를 맞이하고 있다. 이러한 무역환경의 변화에 신속히 대처하기 위해 우리나라는 폭넓은 무역지원정책을 추진하고 무역관리체계를 정비하고 있음에도 불구하고 기대만큼의 실효를 거두지 못하고 있으며, 중소기업들은 국내외 경기의 지속적인 침체로 점차 해외경쟁력을 잃어가고 있다. 수출진흥을 위한 정책지원 전략은 무역환경의 변화에 대한 정확한 인식을 바탕으로 하여 무역중소기업의 무역마케팅구조를 근본적으로 개선하는데 궁극적인 목표를 두고 현장실무지원 중심으로 체계적이고 종합적인 수출지원사업 실행방안을 마련하는 일이 우선시 되어야 할 것이다. 따라서 본고에서는 국내 수출중소기업들을 대상으로 설문조사를 실시하여 이를 바탕으로 정부 수출지원사업 활용현황과 무역진흥정책 추진에 따른 향후과제를 검토 분석해보고, 나아가 기업들과 정부 유관기관과의 협력방안을 도출하는데 있다.

Along with the exponential growth of data businesses, the importance of data containing personal information of use have also increaseing. Particularly, in Korea, as the Data 3 Act was implemented, companies can use personal information more actively through regulatory improvement and stipulation in case of using data containing personal information. In this situation as per the service use, self-sovereign identity technology has emerged that can minimize the provision of personal information in relation to real name authentication and provision of personal information. Recently, services and studies using blockchain have been actively conducted in case of using the self-sovereign identity function for clarity and verification of records according to the use of personal information. In this thesis, by analyzing the characteristics of domestic self-sovereign identity service and the current status and contents of research related to blockchain-based self-sovereign identity technology and we suggest a research direction based on self-sovereign identity technology to reinforce the sovereignty of personal information in the era of the 3rd Data Act do.

This study investigated how cognitive style and training context influenced visual discrimination skill acquisition and transfer under time pressure. This experiment consisted of a screening session, a training session, and a transfer session using random polygon comparison tasks. Screening session was designed to separate participants according to their cognitive style (analytic or holistic). Training session was divided into difficult and easy conditions. In transfer session, participants compared polygon pairs in a novel task. The stimuli were presented for 1.5 seconds to examine the influence of time pressure. Through the all sessions, this experiment measured accuracy and response time. According to the results of this study, analytic group responded as quickly as holistic group in the beginning of training session because time pressure induced them to the holistic strategy. However, as training session progressed, their slopes of reaction time increased, suggesting that their own analytic style emerged. Holistic group showed flatter slopes than did analytic group for training session. Of interest is the slopes increased at the beginning of transfer session, suggesting that they developed analytic strategies in difficult training context. It is suggested individuals differently develop strategic processing skills depending on cognitive styles even under time pressure.
