Images in the textbooks influence the learning process. Students often see pictures before reading the text and these pictures can enhance the power of imagination of the students. The findings of some researches show that the images in textbooks can increase students' creativity. However, when learning major subjects, reading a textbook or looking at a picture alone may not be enough to understand the topics and completely realize the concepts. Studies show that viewers remember 95% of a message when watching a video than reading a text. If we can combine textbooks and videos, this teaching method is fantastic. The "TEXT + IMAGE + VIDEO (Animation)" concept could be more beneficial than ordinary ones. We tried to give our solution by using machine learning Image Classification. This paper covers the features, approaches and detailed objectives of our project. For now, we have developed the prototype of this project as a web app and it only works when accessed via smartphone. Once you have accessed the web app through your smartphone, the web app asks for access to use the camera. Suppose you bring your smartphone's camera closer to the picture in the textbook. It will then display the video related to the photo below.

This study investigated the effect of learning achievements and cognitive load according to different types of presenting learning materials and epistemological beliefs (EB). Learning achievements in this study were composed by retention and transfer of ill-structured problem. A total of 80 college students participated in the study. Prior to the learning, students were guided to fill out a questionnaire regarding epistemological beliefs and a prior knowledge test. The students of each group studied with a different type of reading material: full text (FT), full text including key questions (KeyFT) and full text including a concept map (CmFT). After a session of study was finished, they were asked to complete the posttest: retention and transfer. The results showed that there was a significant difference in transfer achievements. CmFT outperformed higher scores than the other types. There was no significant difference in retention among the groups. It is strongly believed that the types of presenting learning materials may have affected the understanding of ill-structured problem solving skills. Students with sophisticated EB showed higher achievements on retention and transfer than naive-EB and mixed-EB. Even though the data showed decrease of the cognitive load on the type of materials and EB, there were no significant differences on the cognitive load. We should consider a positive effect of types of presenting learning materials and EB enhancing capabilities of solving ill-structured problems in real life.

The purpose of this study is to analyze the symbolic meaning which is immanent in the children´s clothing advertisement text. For the purpose of this research, this study used the semiotic method which are in parallel. Namely, rearranged the R. Barthes´theory and S. Chapman's analysing frame in order to decode meaning which is immanent in the advertisement text, and 1 coded children's clothing advertisement according to the market fractionation cause (age. sex and brand image), and analysed the paradigmatic meaning and socio-cultural meaning- As a result, to carry on the effective children's clothing advertisements. the discriminate paradigmatic system which corresponds with the concept of company brand and the quality of the target consumer should be selected, and the purchaser volition considering desire of target consumer's self image and brand image should be made. Futhermore it should be the social-cultural product reflecting a phenomenon in the social-cultural actual condition. Therefore we must understand the social-cultural meaning in the children's clothing advertisement and then have to establish an advertisement strategy.

본 논문에서는 개념 그래프 기반 검색 시스템의 검색의 성능을 개선시키고자 Hits 알고리즘을 적용하였다. 기존 개념 그래프 기반 검색 시스템의 anchor text분석을 통하여 개념을 추출하고 있는 시스템에서 더 나아가 하이퍼 링크의 선호도의 특성을 살려 하이퍼링크에 문서가 얼마나 연결되어 있는지, 참조하고 있는지에 따라 해당 검색된 문서들의 중요도를 찾아서 순위를 매기는 실험을 하였다. 종래에는 해당 검색어의 빈도순으로 개념의 결과를 나타내 주었는데, 본 시스템 구현 후에 랭킹알고리즘을 적용하여 해당검색에 유용한 정보를 가지고 있는 페이지들(authorities)과 유용한 정보를 보유하고 있는 페이지의 링크를 보유하고 있는 페이지들(hubs)를 각각 순위 순으로 보여주게 되었다. 그리하여 사용자는 실제 검색시에 개념상으로 분류된 문서 중에 중요도가 높은 문서를 사용자에게 우선으로 접하게 되었으며, hub어 의해서 중요도가 높은 문서를 한눈에 볼 수도 있을 뿐 아니라, anchor text 어서 나타나지 않은 중요한 정보를 가진 문서도 검색할 수 있었다.

Skilled typists can type characters or words without looking at keyboard, relying on the finger's relative position. If the relative positions of the fingers can be identified, a virtual keyboard may be accomplished by applying the concept of "DataGlove" or "FingerRing". The virtual keyboard may be efficient as a new mobile input device supporting QWERTY keyboard layout. For the purpose of investigating skilled typing pattern, in this paper the touch-positions of the fingers are measured with a touchscreen while five skilled typists type a long sentence. From these measurements it can be observed that the groups of touch-positions are classified into alphabet characters. Though there are some overlapped groups we can find constant distances capable of being discriminated among the groups from investigation of the change of touch-position for touch-time. Based on the analysis, the prediction algorithm of the constant distance is proposed and evaluated, which is useful for realization of a portable virtual keyboard.le virtual keyboard.

The purpose of the study was to analyze consumers' perceptions of gamification. Based on the analyzed data, we would like to provide data by systematically organizing the concept, game elements, and mechanisms of gamification. Recently, gamification can be easily found around medical care, corporate marketing, and education. This study collected keywords from social media portal sites Naver, Daum, and Google from 2018 to 2023 using TEXTOM, a social media analysis tool. In this study, data were analyzed using text mining, semantic network analysis, and CONCOR analysis methods. Based on the collected data, we looked at the relevance and clusters related to gamification. The clusters were divided into a total of four clusters: 'Awareness of Gamification', 'Gamification Program', 'Future Technology of Gamification', and 'Use of Gamification'. Through social media analysis, we want to investigate and identify consumers' perceptions of gamification use, and check market and consumer perceptions to make up for the shortcomings. Through this, we intend to develop a plan to utilize gamification.
