  • Nowadays with the help of Location-Based Social Networks (LBSNs), users of Point-of-Interest (POI) recommendation service in LBSNs are able to publish their geo-tagged information and physical locations in the form of sign-ups and share their experiences with friends on POI, which can help users to explore new areas and discover new points-of-interest, and promote advertisers to push mobile ads to target users. POI recommendation service in LBSNs is attracting more and more attention from all over the world. Due to the sparsity of users' activity history data set and the aggregation characteristics of sign-in area, conventional recommendation algorithms usually suffer from low accuracy. To address this problem, this paper proposes a new recommendation algorithm based on a novel Preference-Content-Region Model (PCRM). In this new algorithm, three kinds of information, that is, user's preferences, content of the Point-of-Interest and region of the user's activity are considered, helping users obtain ideal recommendation service everywhere. We demonstrate that our algorithm is more effective than existing algorithms through extensive experiments based on an open Eventbrite data set.

  • Records regarding to magnetism in the written Korean history were surveyed. In this article, we depicted how the magnetism (magnet) was understood by the public in the past in the Korea. The records about magnetism could be chronically categorized into three eras; 1) an era of recognizing a magnetic characteristics, 2) era of recognizing a magnetic pole, and 3) era of acquiring a modern knowledge. The written history of the Silla dynasty (BC57-AD935) revealed that a magnet was produced in this era. However, no record about magnet was found in the written history of the Goryo dynasty (918-1392). It was revealed that throughout the Korean history the interest in the magnetism (magnet) was emphasized most in the Josun dynasty (1392-1910). The magnetism (magnet) was most widely exploited in a geomancy. A magnetic compass was used widely to find a merciful direction and place in everyday life. In the era of Josun dynasty, a magnet was exploited as a magnetic compass for a navigation over the sea. An interesting usage of the magnet in the Josun dynasty was found in the pharmaceutical purpose.

  • The purpose of this study is to review two books on the history of Korean literature written in Japanese, taking special interest in ancient Korean literature, examining transcultural patterns between the history of North and South Korean literature and that of Japanese literature, and thereby identifying perceptions and description patterns of the history of Korean literature from the perspective of comparative literature. This study analyzes two books with the same title The History of Joseon Literature written in Japanese by Kim Dongwook and Byeon Jaesoo. The two books are not translations of Korean books but were written in Japanese for Japanese and ethnic Korean readers in Japan. The History of Joseon Literature (1974) by Kim Dongwook mainly compares Joseon literature with Japanese literature. The History of Joseon Literature (1985) by Byeon Jaesoo, an ethnic North Korean in Japan, was written from socialistic perspectives. The two books have different standards for evaluating value of the history of Joseon literature and different perceptions about it. Due to the division between North and South Korea, the history of literature is unfolding in different ways in the two Koreas, and the two books reflect such differences. However, they have several common features. For example, they highly regard the value of literature written in Chinese characters and originality of hangga (a folk song of Silla), Hangeul (the Korean alphabet), and pansori (a form of Korean folk music in which a singer accompanied by a supportive drummer sings and chants an epic story). In addition, they both demonstrated that literature written in Hangeul and that written in Chinese characters interacted with each other as the same Korean literature. When the two books were written, the history of Korean literature had been considered a subunit of the history of East Asian or Chinese literature. However, as this study found, Kim and Byeon wrote the two books from a perspective of departing from this view based on nationalism, re-establishing the value of Korean literature, promoting Japanese people's understanding of the high quality of Korean literature, and imbuing ethnic Koreans in Japan with nationalistic pride.

  • There are two main perspectives in Korea on Korean cultural heritage located overseas: one views it as items that need to be repatriated since they were scattered abroad under unfortunate historical circumstances. The other considers them as a means to more widely promote Korea's culture and long history. A shift in perspective has gradually been taking place in the decades since Korea's liberation from Japanese colonial rule in 1945. This can be noted through three major types of exhibitions. The first type is exhibitions of repatriated cultural heritage that showcase items that were illegally removed from the country but later returned or otherwise acquired through purchase or donation. The Special Exhibition of Returned Cultural Heritage, which was held in 1966 on the occasion of the normalization of diplomatic relations between the Republic of Korea and Japan, emphasized the legitimacy of reclaiming cultural properties that were illegally removed from Korea during the period of Japanese colonial rule. Around the 1990s, special exhibitions of private donations were held, which also highlighted the legitimacy of repatriation. The special exhibition of the Oegyujanggak Uigwe (Royal Protocols of the Joseon Dynasty from the Outer Royal Library) held in 2011 was seen as an opportunity to raise public interest in repatriation, heal the wounds of history, and restore the nation's cultural pride. The second type of exhibition involves borrowing and displaying overseas Korean cultural heritage in accordance with a theme as a means to reenergize and provide a comprehensive view of Korean culture. The exhibitions National Treasures from the Goryeo Dynasty in 1995 and National Treasures from the Early Joseon Dynasty in 1997 (both held at the Hoam Museum of Art) and the Masterpieces of Goryeo Buddhist Painting held at the National Museum of Korea in 2010 underscored the importance of overseas Korean cultural heritage for exploring Korean cultural history. The third type is special exhibitions on the history of the collection of Korean cultural heritage. With Korea's economic growth in the 1980s and the increase in exhibitions and the number of galleries featuring Korean cultural heritage in overseas museums in the 1990s, interest in the history of acquisition also grew. Exhibitions like The Korean Collection of the Peabody Essex Museum in 1994 and Korean Art from the United States in 2012 introduced overseas galleries focused on Korean art and the diverse history of collecting Korean cultural properties. They also examined the perception of Korean art in the United States. These efforts heightened public interest in establishing and supporting Korean galleries abroad. The initiation of more systematic surveys and research on Korean cultural heritage located abroad and the contribution of overseas Korean cultural heritage to the enhancement of the local understanding and promotion of Korean culture have resulted in changes to the perception of overseas Korean cultural heritage in Korea.

  • Event detection and recognition is an active and challenging topic recent in Computer Vision. This paper describes a new method for recognizing events caused by human motion from video sequences in an office environment. The proposed approach analyzes human motions using Motion History Image (MHI) sequences, and is invariant to body shapes. types or colors of clothes and positions of target objects. The proposed method has two advantages; one is thant the proposed method is less sensitive to illumination changes comparing with the method using color information of objects of interest, and the other is scale invariance comparing with the method using a prior knowledge like appearances or shapes of objects of interest. Combined with edge detection, geometrical characteristics of the human shape in the MHI sequences are considered as the features. An advantage of the proposed method is that the event detection framework is easy to extend by inserting the descriptions of events. In addition, the proposed method is the core technology for event detection systems based on context-aware computing as well as surveillance systems based on computer vision techniques.

  • The opinion, that the history of science should be introduced to science lesson, has been continuously emphasized by a group of people who supported the needs of science and scientific process, nature of science, and the interaction between science and society. When the importance of the integrated science education is emphasized, the history of science is suggested as an effective curriculum for it. To respond to this identified interest, we developed a lesson of the history of science by selecting the contents of the history of science as subject topics of the integrated science and by utilizing the findings of previous studies related to the history of science in science educations. To develop the history of science class as a subject of integrated science, we chose 'the age of the earth' as a unit. After the pilot test of the unit in secondary school students, the possibility of offering the lesson as a regular course was examined with analysis of the students' reactions showing its effectiveness.

  • Recently, as an enonomic importance of the Eurasian Continent raises, the necessity of east-west connecting ancient transport roads research is increasing. Although domestic research of eastern-western international exchange in the Eurasia is not yet very active, the studies of history, archaeology, art history, folklore, costume history have been advanced steadily. An attention for the exchange through steppe route originated from the interest in Korean folk and Korean culture and the research range is extending to Xiungnu, Kurgan culture as a direct investigation on the remains of Mongolia and Kazakhstan has been achieved constantly. The art history has been leading the research of exchange which is based on desert and oasis. The field research of Iran, Uzbekistan, Azerbaijan, etc progressed in various routes, and the research on diverse topics including Silla's golden culture, transmission of glass, and the Buddhism is improving. Research on the maritime silk road is weaker, compared to other parts. Buddhist and Hindu temples of Southeast Asia attracted some interest to people, but the research should focus on the restoration of sea route and consideration of its meaning. Research of this part is expected to be more activative, as domestic researchers investigate Don Son culture and Sa Huynh culture of Vietnam by themselves. From now on, we should focus on topics that are not directly connected to Korean history, and Korean culture. Because it is also our duty to study and conserve the culture of entire human community.

  • The purpose of this study was to assess the relationship between the mother's interest in weight control and its association with the preschooler's obesity and weight related concerns. This was a cross-sectional study based on 470 parents' self-reports. To score interests in weight control, mothers rated each of 6 items on a five-point Likert scale ranging from disagree (1) to agree (5). The perceptions of mothers' weights and their children's weights, mothers' Body Mass Index (BMI), preschoolers' Weight-Length Index (WLI) (%), and weight-related concerns were determined. The mothers' BMI was significantly correlated with interest scores of weight control in mothers (r=0.632, p<0.001) while their children's obesity was weakly correlated with the mothers' interest scores (r=0.133, p=0.025). Mothers with a high interest of weight control reported higher percentages of family history of obesity than mothers with lower interests (63.2% vs. 36.8%, p<0.001). Two-thirds of the mothers (65.4%) were accurate in their perceptions about their weights. Similarly, 63.7% of mothers knew exactly their children's weight-statuses. Compared with mothers with low interest in weight controls, mothers with high interest in weight control had lower correct-perceptions about their weights (p<0.05) but higher correct-perceptions about their children's weights. More than two-thirds of mothers (85%) reported not worrying about their children's obesity in the future. Only 14.3% of the mothers were satisfied with their current weight statuses. Three-fourths of mothers preferred exercise as an effective weight-control method for their children, 20% preferred diet therapy and 5.5% preferred behavior modification. More girls were overweight / obese, than boys (overweight: 16.1% (girl) vs. 12.8% (boy), obese: 5.4% (girl) vs. 4.5% (boy)). About 40% of overweight girls' mothers had low interests in their weight controls with low correct-perceptions in their children's weights, which suggests possible elevated risk of obesity, especially in girls, in the future.

  • Instructing "History of Spanish Literature" class faces various types of limits and obstacles, just as other foreign language literature history classes do. Majority of students enter the university without having any previous spanish learning experience, which means, for them, even the interpretation of the text itself can be difficult. Moreover, the fact that "History of Spanish Literature" is traced all the way back to the Middle Age, students encounter even more difficulties and find factors that make them feel the class is not interesting. To list several, such factors include the embarrassment felt by the students, antiquated expressions, literature texts filled with deliberately broken grammars, explanations written in pretentious vocabularies, disorderly introduction of many different literary works that ignores the big picture, in which in return, reduces academic interest in students, and finally general lack of interest in literate itself due to the fact that the following generation is used to visual media. Although recognizing such problem that causes the distortion of the value of our lives and literature is a very imminent problem, there has not even been a primary discussion on such matter. Thus, the problem of what to teach in "History of Spanish Literature" class remains unsolved so far. Such problem includes wether to teach the history of authors and literature works, or the chronology of the text, the correlations, and what style of writing to teach first among many, and how to teach to read with criticism, and how to effectively utilize the limited class time to teach. However, unfortunately, there has not been any sorts of discussion among the insructors. I, as well, am not so proud of myself either when I question myself of how little and insufficiently did I contemplate about such problems. Living in the era so called the visual media era or the crisis of humanity studies, now there is a strong need to bring some change in the education of literature history. To suggest a solution to make such necessary change, I recommended to incorporate the visual media, the culture or custom that students are accustomed to, to the class. This solution is not only an attempt to introduce various fields to students, superseding the mere literature reserch area, but also the result that reflects the voice of students who come from a different cultural background and generation. Thus, what not to forget is that the bottom line of adopting a new teaching method is to increase the class participation of students and broaden the horizon of the Spanish literature. However, the ultimate goal of "History of Spanish Literature" class is the contemplation about humanity, not the progress in linguistic ability. Similarly, the ultimate goal of university education is to train students to become a successful member of the society. To achieve such goal, cultural approach to the literature text helps not only Spanish learning but also pragmatic education. Moreover, it helps to go beyond of what a mere functional person does. However, despite such optimistic expectations, foreign literature class has to face limits of eclecticism. As for the solution, as mentioned above, the method of teaching that mainly incorporates cultural text is a approach that fulfills the students with sensibility who live in the visual era. Second, it is a three-dimensional and sensible approach for the visual era, not an annotation that searches for any ambiguous vocabularies or metaphors. Third, it is the method that reduces the burdensome amount of reading. Fourth, it triggers interest in students including philosophical, sociocultural, and political ones. Such experience is expected to stimulate the intellectual curiosity in students and moreover motivates them to continues their study in graduate school, because it itself can be an interesting area of study.
