Distance learning universities provide online course content. The main methods of providing class contents are on-demand and live-streaming. This means that students are not restricted by time or space. The advantage is that students can take the course anytime and anywhere. Therefore, unlike commuting students, there is no commuting time to the campus, and there is no natural process required to take classes. However, despite this convenient situation, the attendance rate and graduation rate of distance learning universities tend to be lower than that of commuting universities. Although the course environment is not the only factor, students cannot obtain a bachelor's degree unless they fulfill the graduation requirements. In both commuter and distance learning universities, taking classes is an important factor in earning credits. There are fewer time and space constraints for distance learning students than for commuting students. It is also easy for distance learning students to take classes at their own timing. There should be more ease of learning than for students who commute to school with restrictions. However, it is easier to take a course at a commuter university that conducts face-to-face classes. I thought that the reason for this was that commuting to school was a part of the process of taking classes for commuting students. Commuting to school was thought to increase the willingness and motivation to take classes. Therefore, I thought that the inconvenient constraints might encourage students to take the course. In this research, I focused on the act of commuting to school by students. These situations are also applied to the distance learning environment. The students have physical time constraints. To achieve this goal, I will implement a course restriction method that aims to promote the willingness and attitude of students. Therefore, in this paper, I have implemented a virtual school system called "virtual go to school (VG2S)" that reflects the actual route to school.

Breast cancer is among the cancers that may be healed as the disease diagnosed at early times before it is distributed through all the areas of the body. The Automatic Analysis of Diagnostic Tests (AAT) is an automated assistance for physicians that can deliver reliable findings to analyze the critically endangered diseases. Deep learning, a family of machine learning methods, has grown at an astonishing pace in recent years. It is used to search and render diagnoses in fields from banking to medicine to machine learning. We attempt to create a deep learning algorithm that can reliably diagnose the breast cancer in the mammogram. We want the algorithm to identify it as cancer, or this image is not cancer, allowing use of a full testing dataset of either strong clinical annotations in training data or the cancer status only, in which a few images of either cancers or noncancer were annotated. Even with this technique, the photographs would be annotated with the condition; an optional portion of the annotated image will then act as the mark. The final stage of the suggested system doesn't need any based labels to be accessible during model training. Furthermore, the results of the review process suggest that deep learning approaches have surpassed the extent of the level of state-of-of-the-the-the-art in tumor identification, feature extraction, and classification. in these three ways, the paper explains why learning algorithms were applied: train the network from scratch, transplanting certain deep learning concepts and constraints into a network, and (another way) reducing the amount of parameters in the trained nets, are two functions that help expand the scope of the networks. Researchers in economically developing countries have applied deep learning imaging devices to cancer detection; on the other hand, cancer chances have gone through the roof in Africa. Convolutional Neural Network (CNN) is a sort of deep learning that can aid you with a variety of other activities, such as speech recognition, image recognition, and classification. To accomplish this goal in this article, we will use CNN to categorize and identify breast cancer photographs from the available databases from the US Centers for Disease Control and Prevention.

The article explores the prospects and trends for the transformation of some basic concepts of law associated with the development of artificial intelligence systems and the problems of liability for harm caused by a robot. The prospects, conditions and consequences of vesting robots with partial (quasi) or full legal personality are explored. This process should lead to a revision of the concepts of will, subjective side and legal responsibility in the direction of their greater universalization. The legally significant signs of will, legal personality, legal liability in relation to robots, artificial intelligence systems and other complex automated information systems are clarified. The author identifies the following essential factors of legal qualification of an act committed by a robot: goals, reasons for setting goals, connections between the planned result and the action taken, the actual result, the reasons for the difference between the actual result and the planned one. The article pays special attention to the preventive function of legal liability, which, when applied to robot subjects, can be expressed in the following basic procedures. 1. Accounting for legal requirements in the behavior of the robot. 2. Timely adaptation of the robot to changes in legislation and other regulatory legal acts that affect its behavior. 3. Accounting for incidents. 4. Destruction of a series of robots whose actions lead to unacceptable consequences.

최근 CCTV의 영상정보 공개시 타인의 영상에 대해서는 모자이크 처리하여 식별이 불가능하도록 하는 개인정보 보호법이 발표되었다. 반면에 CCTV를 통하여 획득된 영상 데이터를 활용한 범죄 수사는 점차 더 많이 활용되고 있는 추세이다. 이렇게 상반된 2가지의 요구사항에 의해 촬영된 CCTV 동영상을 수사기관 등의 기관에서 요청할 경우 개인정보(개인 얼굴 이미지 등)을 마스킹(Masking)해 배포함으로써 개인정보 유출을 차단하는 마스킹/ 언마스킹 솔루션에 대한 시장의 요구가 크게 성장할 것으로 예측된다. 정보주체가 정보열람 의뢰기관에 정보를 요구하기 전에 객체에 대한 선별 마스킹을 하기 위한 정보보호 솔루션에 있어서 가장 핵심되는 기술은 객체에 대한 추적기술이다. 본 논문에서는 CCTV영상에 대한 후처리로써의 정보보호 솔루션에 적합한 객체추적 알고리즘을 제안한다. 안정적인 추적이 가능하도록 하기 위해 움직임정보와 색상정보를 함께 사용하였다. 그러면서도 시간이 많이 걸리지 않는 컬러 중심점 이동(Color Centroid Shifting) 기반의 방법을 사용하여 추적의 속도 성능을 높였다.

현대사회의 정보화는 컴퓨터와 인터넷을 통해 대량의 정보를 생산 교류하므로 새로운 커뮤니케이션 방식을 탄생시키고 있다. 과거 피동적 방식의 일방적 정보흐름이 능동적 상호작용 방식으로 진화하여 정보생산자와 정보소비자의 구별을 약회시키고 있으며, 온라인상의 인적관계를 강화시키는 Social Networking Service의 사회구조로 발전하고 있다. 따라서 정보의 확산은 사회적 네트워크 구조를 긴밀하게 작용시킴으로 사회적 갈등을 불러일으키는 하나의 요인으로도 작용하기도 하고, 제도와 환경, 개인의 문화적 적응이 과학 기술의 빠른 발전 속도를 따라가지 못함으로 갈등과 혼란을 초래하기도 한다. 이에 본 논문은 정보화 사회의 특성과 진화과정을 살펴보면서 정보화의 파장으로서 사회적 위험요인을 살펴보고 이에 대한 민간시큐리티의 역할을 모색해 보고자 한다. 정보화 사회는 시간과 공간의 영역을 축소시켜 인간생활의 편리성과 간편성을 가져다 준 반면, 비대면성과 익명성이라는 특성으로 인해 많은 사회적 부작용도 발생시키고 있다. 이에 국가차원의 제도적 대책 마련이 이루어지고 있지만 개인생활보호를 위한 민간차원의 보호장치는 아직 논의되지 않고 있다. 주문자 방식의 개인의 생명과 재산을 보호하는 민간시큐리티가 이를 담당해야 할 것이다.

The emergence of new IT technologies and convergence industries, such as artificial intelligence, bigdata and the Internet of Things, is another chance for South Korea, which has established itself as one of the world's top IT powerhouses. On the other hand, however, privacy concerns that may arise in the process of using such technologies raise the task of harmonizing the development of new industries and the protection of personal information at the same time. In response, the government clearly presented the criteria for deidentifiable measures of personal information and the scope of use of deidentifiable information needed to ensure that bigdata can be safely utilized within the framework of the current Personal Information Protection Act. It strives to promote corporate investment and industrial development by removing them and to ensure that the protection of the people's personal information and human rights is not neglected. This study discusses the strategy of deidentifying personal information protection based on the analysis of fake news. Using the strategies derived from this study, it is assumed that deidentification information that is appropriate for deidentification measures is not personal information and can therefore be used for analysis of big data. By doing so, deidentification information can be safely utilized and managed through administrative and technical safeguards to prevent re-identification, considering the possibility of re-identification due to technology development and data growth.

In this busy world actually stress is continuously grow up in research and monitoring social websites. The social interaction is a process by which people act and react in relation with each other like play, fight, dance we can find social interactions. In this we find social structure means maintain the relationships among peoples and group of peoples. Its a limit and depends on its behavior. Because relationships established on expectations of every one involve depending on social network. There is lot of difference between emotional pain and physical pain. When you feel stress on physical body we all feel with tensions, stress on physical consequences, physical effects on our health. When we work on social network websites, developments or any research related information retrieving etc. our brain is going into stress. Actually by social network interactions like watching movies, online shopping, online marketing, online business here we observe sentiment analysis of movie reviews and feedback of customers either positive/negative. In movies there we can observe peoples reaction with each other it depends on actions in film like fights, dances, dialogues, content. Here we can analysis of stress on brain different actions of movie reviews. All these movie review analysis and stress on brain can calculated by machine learning techniques. Actually in target oriented business, the persons who are working in marketing always their brain in stress condition their emotional conditions are different at different times. In this paper how does brain deal with stress management. In software industries when developers are work at home, connected with clients in online work they gone under stress. And their emotional levels and stress levels always changes regarding work communication. In this paper we represent emotional intelligence with stress based analysis using machine learning techniques in social networks. It is ability of the person to be aware on your own emotions or feeling as well as feelings or emotions of the others use this awareness to manage self and your relationships. social interactions is not only about you its about every one can interacting and their expectations too. It about maintaining performance. Performance is sociological understanding how people can interact and a key to know analysis of social interactions. It is always to maintain successful interactions and inline expectations. That is to satisfy the audience. So people careful to control all of these and maintain impression management.
