디지털 카메라의 보급과 U.C.C. 개념의 등장으로 인하여 개인이 생산하는 사진의 양도 많아지고, 이를 감상하는 시간도 많아졌다. 사진이란 추억을 회상하는데 하나의 포인트 역할을 하는 매체이다. 따라서 인간의 감성적인 부분을 많이 자극되는데, 이 과정에서 추가적인 자극을 줌으로써 사용자의 감성을 더욱 자극할 수 있다. 하지만, 기존의 연구들은 디지털 사진을 검색하고 관리하는데 초점이 맞추어져 있었다. 본 논문에서는 사용자가 사진 앨범을 감상할 때에 개별 사진을 분석하여 전체 사진과 가장 잘 어울리는 배경음악을 추천/재생하는 ListenPhoto 시스템을 제안한다. 그리고, 시스템의 필요성에 대한 평가와 시스템 성능에 대한 평가 두 부분으로 나누어 평가를 진행하였다. 사용자들은 이 시스템을 통하여 풍부하게 디지털 사진 생활을 즐길 수 있게 될 것이다.

인터넷 방송은 “통신과 방송의 융합”이라는 시대의 한 흐름 속에서 주목을 받고 있다. 대화형, 개인화, 풍부한 채널자원 등의 특성을 갖는 인터넷 방송은 기존 방송매체와의 차별화를 통해 인터넷 TV, 교육방송 및 주식/뉴스 전달서비스 등의 관련 인터넷 응용서비스 산업의 발전을 주도하고 있다. 인터넷 방송서비스는 여러 수신자를 대상으로 하는 다자간 통신서비스임에도 불구하고, 현재 대부분의 인터넷 방송 전송시스템이 유니캐스트 방식에 의존하고 있다. 이는 네트워크에서의 대역폭 및 송신시스템 장비의 이용 측면에서 비효율적이며 동시 접속자 수 측면에서도 한계를 지닌다. 또한, 유니캐스트 트래픽의 중복 전송으로 인해 네트워크의 과부하 및 병목 현상을 유발할 수 있으며, 이로 인해 전체적인 서비스품질 저하를 초래하고 있다. 본 고에서는 인터넷 방송 전송기술의 효율성을 증진시키고 나아가 관련 산업경쟁력 강화를 위한 멀티캐스트 기술의 적용 방안에 대하여 논의하고, 이를 위해 세부적으로 요구되는 멀티캐스트 기술에 대하여 살펴본다.

Nous conduisons tous les codes graphiques specifiques d'un genre de la bande dessinee coreenne, sounziang manwha, e la "decorativite". Afin de mieux rendre compte de cette decorativite, nous suivons un chemin qui aborde des divers etats de cette specificite. Etant donne que la decorativite n'est pas originaire, ni propre totalement au genre, nous nous interessons e ses formes differentes dans les genres precedentes : dessin de mode, dessin lyrique, illustration, affiche, shojo manga, etc. Ils nous permettent e voir des ressemblances et des differences dans les styles graphiques. Nous parvenons enfin e comprendre ce que la decorativite en bande dessinee est attachee intimemnt aux traits fictifs et irreels du diegese.

This study examined the effect of e-learning contents with different dual-coding, media-richness, and cognitive-load degree on learning. To do so, after dividing summary and explanation presentation methods in e-learning contents according to information's quantity and kind, the effects on teaching presence and academic achievement were examined. The summary presentation method was produced as text type and text+illustration type and the explanation presentation method as audio type and audio+video type. The results of this study are as follows. First, in the summary method, the text+illustration type had significantly higher teaching presence than text type. Second, in the explanation method, the audio type was found to be significantly higher than the audio+video type. Third, the interaction between the summary method and explanation method was found to be significant in teaching presence and academic achievement.

Recently, tremendous amounts of unstructured text data that is distributed through news, blogs, and social media has gained much attention from many researchers and practitioners as this data contains abundant information about various consumers' opinions. However, as the usefulness of text data is increasing, more and more attempts to gain profits by distorting text data maliciously or nonmaliciously are also increasing. This increase in spam text data not only burdens users who want to obtain useful information with a large amount of inappropriate information, but also damages the reliability of information and information providers. Therefore, efforts must be made to improve the reliability of information and the quality of analysis results by detecting and removing spam data in advance. For this purpose, many studies to detect spam have been actively conducted in areas such as opinion spam detection, spam e-mail detection, and web spam detection. In this study, we introduce core concepts and current research trends of spam detection and propose a methodology to detect the spam tag of a blog as one of the challenging attempts to improve the reliability of blog information.

This paper analyses meta-data systems for serials in order to provide the fundamental infrastructure for serials-sharing systems based on semantic interoperability. According to the primitive features of serials information, meta-data for serials are classified into 3 main subsystems: serial identification Information, serial bibliographic information and serial holding information. The serial identification information that play the important role of the primary key in library management systems should be refined to accommodate serials with digital formats. Although MARC formats have been commonly used for the description of serial bibliographic information, a new meta-data format for serial bibliographic information that harmonize with the abundance of meta-data elements in MARC and the simplicity of DCMI. For serial holding information, the newly proposed standards such as ANSI/NSIO Z39.50 are adequate to grasp the varieties of serial holding patterns. It should be able to differentiate the level of description by means of the types of serial information services. As the current computing technology generally uses XML for the representation and Process of information, the meta-data system for serials should be based on XML.

NOS education through the history of science is regarded effective. However, science teaching has been criticized for not considering the interest of the learners enough and providing the context of learning themes that hinder the understanding of NOS. This study intends to convey the NOS element through the rich context of storytelling. The theme of the story is the history of continental drift, in which, the debate of many scientists and Wegener's creativity are prominent. Of the various media that deliver storytelling, the most powerful medium that leads to personal immersion is computer games, and among many kinds of games, the main genre of storytelling is role-playing games (RPGs). We developed the science history role-playing game (SHRPG) focusing on continental drift. The game development procedure followed Kim's 4F process (2017), which consists of the Figure Out, Focus, Fun Design, and Finalize. The story was constructed based on the NOS elements of Lederman et al. (2002), namely creativity and imagination demand, subjectivity, socio-cultural personality and tentativeness, which are all present in the story of the continental drift theory. The mechanics and rules of the RPG included quests, rewards, quizzes, NOS scores, and rankings. In the final phase of development, the game developed was pilot tested four times. The results of the tests showed that students' understanding of NOS through SHRPG has increased, especially in the creativity domain. The students' satisfaction with the fun, sympathy, and immersion during the game was very high.

Rice straw is one or the main renewable energy sources in Korea. Bio-oil is produced from rice straw with a lab-scale equipment mainly with a fluidized bed and a char removal system. It was investigated how the reaction temperature affected the production of bio-oil and the efficiency of a char removal system. To elucidate how the temperature depended on the production of bio-oil, experiments were conducted at $466^{\circ}C,\;504^{\circ}C\;and\;579^{\circ}C$, respectively. The mass balance was established in each experiment, and the produced gas and oil were analyzed with the aid of GCs and a GC-MS system. The char removal system is composed of a cyclone and a hot filter. Tn the experiments, we observed that the production of bio-oil was decreased with temperature, and the bio-oil contained very useful chemicals.

Although having only become a unified nation in latter 19th century, Germany saw a movement centered on intellectuals to find culture via mental revolution after experiencing much confusion amidst rapid urbanization and materialism. Having expressed as they are such psychological states as anger, sorrow, repression, etc., which arise in reality, by remaining faithful to instinctive sensibility, the form naturally becomes distorted or exaggerated and continues on the tradition of romanticism of a powerful, dark, and introverted atmosphere. Having been discontinued after being branded as 'decadent art' by the Nazis of Fascism, expressionist art has returned in latter 20th century mainly centered on Germany, and this merits our attention. While neo expressionists actively use various objets and media, they metaphorically express hope about Germany's culture and society by again placing on the screen figures, myths, and symbols using rough brush touch, rich colors, etc., which past expressionists enjoyed using to represent the inner world of humans. As such, by examining expressionism, which can be seen as the origin of neo expressionism, we will discover the context in which these people conform to Germany's traditional romanticism and how they inherited and developed it.
