최근 청소년들의 스마트 단말 사용이 급격히 증가하면서, 스마트 단말을 통하여 유해 콘텐츠에 접근하는 비중이 점점 더 늘어나고 있다. 이에 본 논문에서는 스마트 단말에서 스트리밍 콘텐츠가 실행되는 메커니즘을 분석하고, 이를 기반으로 실행 이벤트의 연관성을 분석하여 스트리밍 콘텐츠가 재생되는 시점을 자동으로 탐지할 수 있는 방법을 제안하였다. 제안된 방법을 사용하면 스마트 단말에서 스트리밍 유해 콘텐츠를 효과적으로 차단 할 수 있을 것으로 기대된다.

Clausewitz’s theory of war can be divided between the theory of conduct of war and the theory of preparations for war, and the theory of war that Clausewitz means, is the theory of conduct of war. But before Clausewitz, men regarded a theory of preparations for war as the theory of war. The theory of preparations for war concerns generally about the material side of war, but not its spiritual aspect. The activity of war is basically a human spiritual and psychological action. And because the war is dangerous, the anxiety occurs and diverse human feelings, for example courage, have been required. Also the informations in war is normally very uncertain, so an insight of the commander is in war very needed. The Theory of war has to consider this spiritual aspect. To end the war and to acquire the peace, an excellent talent of commander is necessary. And it is a genius. Men who are difficult to move but have strong feelings, these are the men who are best able to be a genius.

Stereo matching technique is used in many practical fields like satellite image analysis and computer vision. In this paper, we suggest a method to extract a target object image from a complicated background. For example, human face image can be extracted from random background. This method can be applied to computer vision such as security system, dressing simulation by use of extracted human face, 3D modeling, and security system. Many researches about stereo matching have been performed. Conventional approaches can be categorized into area-based and feature-based method. In this paper, we start from area-based method and apply area tracking using scanning window. Coarse depth information is used for area merging process using area searching data. Finally, we produce a target object image.

The purpose of this study was to clarify the relationship between life style and housing satisfaction of high school students. This is the investigation of which 1015 high school students live in Chonbuk province. In this statistical analysis, SPSS program was utilized to calculate percentage, mean and standard deviation. Also. these materials were verified by t-test, one-way ANOVA, Pearson's correlation coefficient. The main results of this study were as follows. There was a significant difference between life style and housing satisfaction, according to demographic variables and housing characteristic variables. The entire life style has been appeared high type of a along with PC. Most of students has been appeared high in health and security of housing. Also, correlation of life style and housing satisfaction showed significantly. On the basic of these results, it can be suggested : It is necessary to have the righteous understanding about life style and housing satisfaction, of high school students for advisable guidance of housing education. It needed to continue diversified researches considering spread of life style 'with PC' and enough awareness of health and security in housing satisfaction.

In this paper, a novel data transferring method is introduced that can transmit sensor data without using data bandwidth or an extra-processing cycle in a delay insensitive network. The proposed method uses human devices as Mules, does not disturb the device owner for permission, and saves energy while transferring sensor data to the collection hub in a wireless sensor network. This paper uses IP addressing technique as the data transferring mechanism by embedding the sensor data with the IP address of a Mule. The collection hub uses the ARP sequence method to extract the embedded data from the IP address. The proposed method follows WiFi standard in its every step and ends when data collection is over. Every step of the proposed method is discussed in detail with the help of figures in the paper.

With the increasing reliance of computing systems in our everyday life, there is always a constant need to improve the ways users can interact with such systems in a more natural, effective, and convenient way. In the initial computing revolution, the interaction between the humans and machines have been limited. The machines were not necessarily meant to be intelligent. This begged for the need to develop systems that could automatically identify and interpret our actions. Automatic gesture recognition is one of the popular methods users can control systems with their gestures. This includes various kinds of tracking including the whole body, hands, head, face, etc. We also touch upon a different line of work including Brain-Computer Interface (BCI), Electromyography (EMG) as potential additions to the gesture recognition regime. In this work, we present an overview of several applications of automated gesture recognition systems and a brief look at the popular methods employed.

The improvement of high-tech is closely linked with the improvement of the man himself, technogenesis affects anthropogenesis, and human development signifies transhumanism. Informatization and virtualization, digitalization and computerization cover more and more areas of human activity one can record and state the actualization and accentuation of what is happening online and it kind of sacralization, alibization and deification. The anthropological potential of IT also increases and expands accordingly. With the help of technology, scientists hope to establish communication with animals, study their language and intelligence, use elements of AI, to promote the protection of the rights of robots and cybernetic organisms.

Decision-making refers to identifying the best alternative among a set of alternatives. When a set of criteria are involved, the decision-making is called multi-criteria decision-making (MCDM). In some cases, the involved criteria may be prioritized by the human decision-maker, which determines the importance degree for each criterion; hence, the decision-making becomes prioritized multi-criteria decision-making. The essence of prioritized MCDM is raking the different alternatives concerning the criteria and selecting best one(s) from the ranked list. This paper introduces a generic multi-level algorithm for ranking multiple alternatives in prioritized MCDM problems. The proposed algorithm is implemented by a decision support system for selecting the most critical short-road requests presented to the transportation ministry in the Kingdom of Saudi Arabia. The ranking results show that the proposed ranking algorithm achieves a good balance between the importance degrees determined by the human decision maker and the score value of the alternatives concerning the different criteria.

중첩 개체명 인식(Nested Named Entity Recognition)은 하나의 개체명 표현 안에 다른 개체명 표현이 들어 있는 중첩 구조의 개체명을 인식하는 작업으로, 중첩 개체명 인식을 위한 학습데이터 구축 작업은 일반 개체명 인식 학습데이터 구축보다 어렵다는 문제가 있다. 본 논문에서는 이러한 문제를 해결하기 위해 Few-shot Learning 환경에 강건한 중첩 개체명 인식 모델을 제안한다. 이를 위해, 기존의 Biaffine 중첩 개체명 인식 모델의 출력 레이어를 라벨 의미 정보를 활용하도록 변경하여 학습데이터가 적은 환경에서 중첩 개체명 인식의 성능을 향상시키도록 하였다. 실험 결과 GENIA 중첩 개체명 인식 데이터의 5-shot, 10-shot, 20-shot 환경에서 기존의 Biaffine 모델보다 평균 10%p이상의 높은 F1-measure 성능을 보였다.

Chatbots have become very popular in our times and are used in several fields. The emergence of chatbots has created a new way of communicating between human and computer interaction. A Chatbot also called a "Chatter Robot," or conversational agent CA is a software application that mimics human conversations in its natural format, which contains textual material and oral communication with artificial intelligence AI techniques. Generally, there are two types of chatbots rule-based and smart machine-based. Over the years, several chatbots designed in many languages for serving various fields such as medicine, entertainment, and education. Unfortunately, in the Arabic chatbots area, little work has been done. In this paper, we developed a beneficial tool (chatBot) in the Arabic language which contributes to educating people about the Prophet's biography providing them with useful information by using Natural Language Processing.
