Learning from human behaviors in the real world is essential for human-aware intelligent systems such as smart assistants and autonomous robots. Most of research focuses on correlations between sensory patterns and a label for each activity. However, human activity is a combination of several event contexts and is a narrative story in and of itself. We propose a novel approach of human activity prediction based on event cognition. Egocentric multi-sensor data are collected from an individual's daily life by using a wearable device and smartphone. Event contexts about location, scene and activities are then recognized, and finally the users" daily activities are predicted from a decision rule based on the event contexts. The proposed method has been evaluated on a wearable sensor data collected from the real world over 2 weeks by 2 people. Experimental results showed improved recognition accuracies when using the proposed method comparing to results directly using sensory features.

해외의 대형 과학 연구 프로젝트에서는 연구 활동에 대한 대국민 홍보와 교육적 활용을 위한 다양한 형태의 콘텐츠를 제작하여 배포하고 있다. 그러나 국내에서는 연구 활동과 성과의 대국민 홍보 부족과 교육적 활용이 저조하여 과학 연구에 대한 대국민 인지도가 상대적으로 낮다. 따라서 국내에서도 천문학 연구에 대한 홍보와 일반인들의 이해 증진을 위하여 대형 천문학 연구에 대한 다양한 콘텐츠를 개발하고 보급하는 것이 절실히 필요하다. 본 발표에서는 2015년 구축이 완료된 KMTNet 연구 프로젝트의 교육 콘텐츠를 개발하기 위한 첫 번째 단계로 Apple iBooks Author를 활용한 e-book과 교육활동지 개발을 소개하고자 한다. 개발된 교육 콘텐츠를 배포하여 많은 국민들이 천문학 연구 및 성과에 대한 관심을 갖고 또한 천문학 연구 활동에 대한 올바른 인식 제고에 기여할 것으로 생각된다. 또한 다른 대형 천문학 프로젝트들의 다양한 교육매체 개발 및 활용에 대한 방향을 제시하고 천문학 대중화에 관심 있는 여러 사람들의 의견을 들어보고자 한다.

In this study, Q methodology was applied to investigate the subjective evaluation of department jumpers and characteristics of each type of recognition for college students. As a result of analyzing, they were classified into three types. Type 1 was recognized that the department jumper plays a role of giving a sense of belonging to the department and promoting the department. In addition, it was analyzed that wearing a department jumper would be cautious, but the activities were comfortable and people around me gave good evaluations and thought it had the effect of enhancing my confidence. In the case of type 2, the department jumper was satisfied because it was an easy-to-work and non-fashionable design, and was always worn when going to university. Type 3 was a type that gives a sense of belonging when wearing the department jumper, and that it was good for the department jumper to follow the fashion. It is thought that a department jumper with a good fit should be developed by reflecting the physical characteristics, showing the image or symbolism, so that the department jumper of college students can function as a uniform.

In modern society, the importance of leisure has been already recognized widely. Recently, interest in participation in more active leisure activities is growing. Furthermore, environmental concerns stemmed from global warming came to the fore. Thus, the purpose of the current study was to examine the effect of recreation specialization representing people who are participating in more active leisure activities on environmental attitudes. A total of 393 college students participating in physically active club activities were selected for this study. Main findings were as follows; First, overall recreation specialization had strong positive effect on environmental attitude. Second, out of sub-factors of recreation specialization, affective specialization had positive influence on environmental attitude. Finally, out of sub-factors of affective specialization, attraction positively affected environmental attitude. This study suggests that individuals who participate in leisure activities more actively are more conscious of environmental problems.

음성인식, 행동패턴인식, 텍스트마이닝 등 사람의 자연스러운 사회적인 활동을 통해 감성을 분석하려는 연구는 지속적으로 증가하고 있다. 특히 SNS는 현대사회에서 없어서는 안 될 소통의 도구로 자리 잡았기 때문에 SNS의 비정형데이터를 이용한 감성분석은 마케팅 분야에서 중요한 활용도구로 사용되고 있다. 이러한 추세에 따라 한국어에 대한 감성인식 역시 다방면으로 분석, 활용되고 있고 한국어의 어순과 표현방식, 중의성, 방언 등의 몇 가지 특징으로 인해 영어와는 다른 방식으로의 접근방식에 대한 필요성이 많은 연구에서 논의되고 있다. 따라서, 이 연구에서는 이러한 한국어의 특징을 수용하여 분석할 수 있도록 시계열 분석에 유용한 LSTM과 중복단어에 대한 가중치를 적용하여 한국어 감성분석을 진행해보고자 한다.

This study is aimed to figure out the way Yoon Hee-sun perceived the real situations of the society under the Japanese ruling and responded to overcome difficulties in the process of anti-Japanese independence movement. Yoon Hee-sun played an important role as a female activist of the righteous army movement in Kangweon-do and Manchuria. She was a daughter-in-law of Yu Hong-seok, wife of Yu Jae-won, and mother of Yu Don-sang. Three generations of her family had taken the lead in anti-Japanese independence movement. The Yus belonged to a school of 'Hwaseo' and devoted their lives to the independent movement based on the thought of 'wijung chuksa sasang', which means 'defending orthodoxy and rejecting heterodoxy'. They desired to go back to the past and recover as it was rather than building a new society. Therefore, their fights against Japan's invasion were not for establishing a modern nation-state but for recovering the royal authority of the existing order. Both her maiden home and her in-laws belonged to a school of 'Hwaseo' and Yoon Hee-sun couldn't go out of the boundary of her family background. Also, the motivation of her participation in the righteous army movement was based on the confucian values such as loyalty to the king, filial piety and fidelity. In particular, she possessed a high level of self-awareness not only as a wife but also as a woman. On the basis of this, she faced up to reality. For the more effective way of revolt against Japan's invasion, she determined to change the perception of women identified only as a wife of somebody. She thought her duty was to enlighten women through 'education'. As a result, manifestoes and songs supporting the righteous army movement were used as a powerful method.

The virtual world is simulated in terms of agents and the environment as the real world. Agents are able to perceive and recognize objects as well as components of the environmental elements in the virtual world. As a result, they are able to autonomously act in terms of their decision. They generate diverse situation that make the user to feel familiarity as they would be have like human beings. Such situations are constructed in terms of the concepts of the entities, relations and activities, and agents accordingly recognize the situations in terms of these concepts. In this paper, we propose the method to recognize and represent the shapes which are the most important feature among objects. Various shapes are represented in terms of primitive shapes and their spatial relations in depth. We use distance, direction, and orientation in order to represent basic spatial relation. In order to simplify basic signal processing, objects dynamically send messages of self information to agents, and refer to ontology as the knowledge base of the virtual world. Agents perceive the information from objects by comparing with schematic knowledge and instance knowledge in ontology.

E-mail is one of the important tools for communicating with people in everyday life. With COVID-19 (Coronavirus) increasing non-face-to-face activity, security incidents through e-mail such as spam, phishing, and ransomware are increasing. E-mail security incidents are increasing as social engineering attack using human psychology rather than arising from technological weaknesses that e-mails have. Security incidents using human psychology can be prevented and defended by improving security awareness. This study empirically studies the analysis of changes in response to malicious e-mail due to improved security awareness through malicious e-mail simulations on executives and employees of domestic and foreign company. In this study, the factors of security training, top-down security management, and security issue sharing are found to be effective in safely responding to malicious e-mail. This study presents a new study by conducting empirical analysis of theoretical research on security awareness in relation to malicious e-mail responses, and results obtained from simulations in a practical setting may help security work.
