In modern society, everyone can easily access the Internet and freely express their opinions or ideas on Web bulletin boards or SNS. At the same time, they are often used as a place of slandering and the spreading of false information about celebrities such as entertainers and politicians. Typically people use the screen capture method to submit web posts as evidence in lawsuits. But it is difficult to get these accepted as evidence in court because screen captured images are easily forged and tempered. Therefore, as described above, using "Proxy Browser", we propose a screen capture authentication system for web posts that protects forging and tempering to use as digital evidence in court.

With the rapid development of e-commerce, many customers can now express their opinion on various kinds of product at discussion groups, merchant sites, social networks, etc. Discerning a consensus opinion about a product sold online is difficult due to more and more reviews become available on the internet. Opinion Mining, also known as Sentiment analysis, is the task of automatically detecting and understanding the sentimental expressions about a product from customer textual reviews. Recently, researchers have proposed various approaches for evaluation in sentiment mining by applying several techniques for document, sentence and aspect level. Aspect-based sentiment analysis is getting widely interesting of researchers; however, more complex algorithms are needed to address this issue precisely with larger corpora. This paper introduces an approach of knowledge representation for the task of analyzing product aspect rating. We focus on how to form the nature of sentiment representation from textual opinion by utilizing the representation learning methods which include word embedding and compositional vector models. Our experiment is performed on a dataset of reviews from electronic domain and the obtained result show that the proposed system achieved outstanding methods in previous studies.

SNS의 확산으로 대중들은 제품, 서비스, 사회적 이슈 등 다양한 도메인에 대하여 자신의 기분이나 의견을 적극적으로 표현하고 있다. 이에 따라 SNS를 분석하여 제품의 수요, TV 시청률, 주가 등의 다양한 현상을 예측하는 데 있어 감성분석을 활용하는 연구가 활발히 진행되고 있다. 감성분석은 각 어휘에 대한 품사, 극성, 감성지수를 규정하고 있는 감성사전을 기반으로 이루어진다. 하지만 동일한 단어라도 도메인에 따라 중요도가 달라지기 때문에 도메인의 특성을 고려한 감성사전을 사용해야 할 필요성이 있다. 따라서 본 연구에서는 다양한 도메인에 대하여 각각의 특성에 맞게 더욱 정확한 감성분석을 할 수 있도록 도메인 맞춤형 감성사전을 구축하는 기법을 제안한다. 도메인 별로 긍 / 부정 평가에 있어 중요한 척도가 되는 단어들을 도메인 감성어휘로 선별하여 목록을 구축하고, 각 감성어휘의 중요도에 따라 도메인 감성지수를 새롭게 정의하였다. 실험 결과, 평가 도메인에 적합한 감성사전이 다른 도메인의 감성사전 및 범용 감성사전보다 우수한 성능을 보였다. 이를 통해 도메인 맞춤형 감성사전 구축기법의 효용성을 확인하였다.

참여적 디자인은 사용자의 경험을 디자인 하기 위한 방법으로, 사용자 자신이 디자인의 주체가 되어 자신의 아이디어를 적극적으로 제안하고 반영하는 방법을 말한다. 우리는 만 3~5 세의 미취학 아동을 참여 디자인의 사용자 대상으로 하였으나, 이 연령대의 어린이는 자신의 의사를 제대로 표현할 수 있는 능력이 부족하여 자신의 느낌과 생각을 정확히 전달하기 어려우므로 전통적인 참여적 디자인 방법을 그대로 사용하는 것은 어렵다. 본 논문에서는 사례를 통하여 실제 어린이 사용자를 대상으로 한 참여적 디자인 방법을 소개한다. 실제 유치원과의 긴밀한 연계를 통해 진행하였으며 현직 유치원 교사가 전체 디자인 프로세스에 참여하였다. 디자인 아이디어를 도출하고 검증하는 단계와 프로토타입의 파일럿 테스트 단계에서 어린이들이 직접 참여하였으며, 그들의 반응과 의견이 디자인에 적극적으로 반영되었다. 본 연구는, 어린이 제품의 디자인을 위해 실제 어린이 교육 기관과 연계한 새로운 형태의 참여적 디자인 방법의 개발과 적용에 대한 사례를 보여준다.

This study aimed to understand how people perceive the transition from offline to online classes at universities during the COVID-19 pandemic. To achieve the goal, we collected tweets related to online classes on Twitter and performed sentiment and time series topic analysis. We have the following findings. First, through the sentiment analysis, we found that there were more negative than positive opinions overall, but negative opinions had gradually decreased over time. Through exploring the monthly distribution of sentiment scores of tweets, we found that sentiment scores during the semesters were more widespread than the ones during the vacations. Therefore, more diverse emotions and opinions were showed during the semesters. Second, through time series topic analysis, we identified five main topics of positive tweets that include class environment and equipment, positive emotions, places of taking online classes, language class, and tests and assignments. The four main topics of negative tweets include time (class & break time), tests and assignments, negative emotions, and class environment and equipment. In addition, we examined the trends of public opinions on online classes by investigating the changes in topic composition over time through checking the proportions of representative keywords in each topic. Different from the existing studies of understanding public opinions on online classes, this study attempted to understand the overall opinions from tweet data using sentiment and time series topic analysis. The results of the study can be used to improve the quality of online classes in universities and help universities and instructors to design and offer better online classes.

The foundation of the development in modern typography is based on the era of International Typographical Style and Modern Typography that valued morphological functionality and rationality to achieve an accurate conveyance of meaning. However, with the advance of postmodernism, the view that the aesthetic and conceptual aspect must be included in its interpretation rather than its rational functionality was prominent. Indeed, the works of Dan Friedman and April Greiman, two graphic designers that are known to be the most representative of the post-modernistic era, displayed that graphic design works can also serve as a method for a more free artistic expression, unlike works of Modern Typography. This move towards aesthetic graphics was first started by Wolfgang Weingart. His various attempts at expanding the concept of typography had a significant impact on the development of New Wave and his experimentalist attitude brought about a ground-breaking change to the functional design and formative expression of modern typography. However, this thesis will consider the theoretical background of the typographical designs displayed in Wiengart's works and the experimental methods thereof, and will not attempt to evaluate Weingart's pioneering role and achievements. Furthermore, this thesis will shed new light on the argument that the Weingart's works are not based on the authorship view of post-modernistic typography and are rather utilized to expand the concept of typography based on a syntactical approach.

Early childhood cultural and artistic education is a process of expressing oneself and understanding society, which has a great impact on the lives of young children. It utilizes the principle of individualization, which means that individual diversity should be considered because each toddler has different developmental characteristics; the principle of play-centeredness, which means that toddlers form active attitudes toward experiential activities through enjoyment through play; the principle of integration, which is the foundation for holistic development; and the principle of direct experience, which means that toddlers have the experience of touching and manipulating materials. In the introduction, children are encouraged to explore and think about materials, read and share books together, and express their thoughts creatively through artistic expressions such as art, music, physical expression, drama, movies, and photography in the first and second phases. In the final stage, a teaching and learning plan was developed that consisted of a circle time for the children to share their opinions with each other in the process of appreciating the results created by the children and presenting their thoughts. As the educational effectiveness of early childhood cultural arts education is best developed in the early childhood period, when learning is emphasized by children exploring according to their interests, this study presented a learning guidance plan that reflects various educational methods and genre convergence education that can be applied to early childhood cultural arts education.

The outdoor space of an elementary school is the most familiar and most educational area for children. A paradigm shift in education has demanded a new role and direction for these outdoor spaces. The construction of children-friendly spaces, however, lags behind. The child-participatory design process is very meaningful at a time when many outdoor spaces have difficulties in reflecting the varied and specific demands of children. This study realized the necessity for a design that includes a child-participatory design process in construction the outdoor spaces of elementary schools. Through reference study and a theoretical approach of related laws, this study established a child-participatory design process model and applied it to Seoul Don-Am Elementary School. The design process included playing games and providing interesting tools to increase the participation of children in suggesting and presenting their opinions more freely. The design process of this study is described in five steps(eliciting interest in and recognition of the target space, Understanding children's expectations and the expressing thereof, Establishing factors for planning, Visualizing and arranging spaces, and Decision-making and building a final design plan). This process was applied to the planning and design of an outdoor space for Seoul Don-Am Elementary School. In this study, it is clear that the design of the participators and experts have a different purpose. Thus, the process of the design has more meaning than the final product. In addition, it is expected that an improvement in both tangible and intangible designs will be seen. Using a participatory design process, this study successfully improved the facilities and arrangement planning of an outdoor space. At the same time, it also enhanced the interest and participation of children in the process of creating the kind of school they desire. The significance of this study is that it has suggested an effective model to reflect the demands of children, the true users of the outdoor space, and the results were actually applied to elementary school outdoor planning and designing. This study enhanced the awareness of school members in the process of building the school's outdoor space.
