본 연구는 온라인 게임공간에서 게이머들이 어떻게 서로 다른 가치관과 행동 패턴을 드러내는지를 확인하고 이를 통해 온라인 게임세계의 문화를 이해하고 분석하기 위해 실시되었다. 전 세계에서 가장 많은 게이머들이 활동하고 있고, 한국과 일본에서 동시에 서비스되고 있는 온라인 게임인 〈리니지〉의 게이머들을 대상으로 온라인 설문조사를 실시하여 '라이프 스타일' 분석틀을 이용해서 이들이 게임공간에서 보이는 행동을 분류하였다. 글 결과 한국과 일본의 리니지 사용자들에게서 거의 유사한 세 가지 라이프스타일 패턴이 추출되었으며 한국과 일본에서 라이프스타일에 따른 행동 패턴이 일관적으로 나타나고 있음을 확인하였다. 도한 한국과 일본의 문화적 차이는 각 라이프스타일 프로파일의 극단성과 분포비율에 의해 반영되는 것으로 확인되었다. 일본의 탈사회적 게이머는 한국의 그것에 비해 더 극단적인 반면 전체 응답자 중에서 차지하는 비율이 적었고 게임 세계에서의 사회 경제적 위치도 낮았으며 한국에서는 비교적 적은 비율을 차지하던 싱글 플레이어 유형이 일본에서는 가장 많은 비중을 차지하는 것으로 나타났다. 또한 일본의 게이머들은 라이프스타일에 상관없이 대부분이 게임 공동체에 가입하는 반면 한국의 게이머들은 라이프스타일에 따라 공동체 참여율이 달랐지만 전체적인 참여율은 일본에 비해 높았다. 이러한 차이는 일본 게임세계에서 공동체 참여는 기본적인 의무인 반면 한국에서는 현실적인 이익과 직결된 활동임을 시사한다. 또한 게임몰입수준은 한국보다 일본의 리니지 게이머들이 높았다. 아시아 각 국에 한국에서 개발한 동일한 온라인 게임이 확산되어 있는 현황을 고려할 때, 온라인 게이머의 라이프스타일 척도는 한국과 일본뿐만 아니라 대만과 중국, 홍콩, 그리고 미국과 같은 리니지 게임이 서비스되는 모든 국가의 문화적 차이를 이해하고 과학적으로 분석할 수 있는 방법이 될 수 있을 것으로 기대된다. 의미를 되새기는 것으로 짧은 연구를 시작하겠다. 등은 활성 값이 70% 이상으로 퇴적물 독성이 상대적으로 낮았다. 이중나선 DNA 함량은 28.4 % - 49%로 대조군에 비해서 감소가 크다. 대부분의 정점이 대조군의 30% 내외로 정점 간의 차이는 크지는 않다. 그러나 다른 측정자료와 같이 정점 22에서 18%로 최소치를 나타내고, 정점 2, 12에서 20% 내외의 값을 보인다. 종합적으로 볼 때 오염물질의 유입이 크고, 광양제철 인근 정점 들이 모두 다른 정점에 비해서 낮아서, 퇴적물 독성이 높은 정점으로 조사되었다.hiwo의 광합성 능력은 낮은 농도들에서는 대조구와 유사하였으나, 5 $\mu\textrm{g}$/l의 높은 농도에서는 초기에 매우 낮은 광합성 능력을 보이다가 시간이 경과하면서 대조군보다 더 높은 경향을 나타냈다. 이러한 결과는 식물플랑크톤이 benso[a]pyrene의 낮은 농도에서 노출될 때는 이 물질을 탄소원으로 사용할 가능성이 있음을 시사한다. 본 연구의 결과들은 연안해역에 benso[a]pyrene과 같은 지속성 유기오염물질이 유입되었을 때 내정여부에 따라 식물플랑크톤 군집내 종 천이와 일차생산력에 크게 영향을 미칠 수 있음을 시사한다.TEX>5.2개)였으며, 등급별 회수율은 각각 GI(8.5%), GII(13.4%), GIII(43.9%), GIV(34.2%)로 나타났다.ments of that period left both in Japan and Korea.

Vision-based Human computer interaction is an emerging field of science and industry to provide natural way to communicate with human and computer. Especially, recent increasing demands for mobile augmented reality require the development of efficient interactive technologies between the augmented virtual object and users. This paper presents a novel approach to construct marker-less mobile augmented reality object and control the object. Replacing a traditional market, the human hand interface is used for marker-less mobile augmented reality system. In order to implement the marker-less mobile augmented system in the limited resources of mobile device compared with the desktop environments, we proposed a method to extract an optimal hand region which plays a role of the marker and augment object in a realtime fashion by using the camera attached on mobile device. The optimal hand region detection can be composed of detecting hand region with YCbCr skin color model and extracting the optimal rectangle region with Rotating Calipers Algorithm. The extracted optimal rectangle region takes a role of traditional marker. The proposed method resolved the problem of missing the track of fingertips when the hand is rotated or occluded in the hand marker system. From the experiment, we can prove that the proposed framework can effectively construct and control the augmented virtual object in the mobile environments.

Recently, traditional books based on printing on the paper have expanded to e-book media in smart device because of developing digital technology. Especially, app book applied application makes users' experience increase and provides immersion to them, because it allows them basically delivering information, educational effect and fun elements with multimedia technology. There are various experimental trials to make enhance effect of reformatting for application media. The purpose of this study is to analyze reformatting effect for app book with funology which is convergence of digital technology and a fun. Then this article would provide design guide and be applied to new application contents. For this research, the first of all, we would discuss concept and elements of funology by publication including thesis, articles, and books. Secondly, this article will be focused on 'Moo, Baa, La La La!' which is reformatting application for iPad to analyze type of funology. Thirdly, we would make sure that app book makes users get emotional effect comparing original book by FGI(Focus Group Interview). In conclusion, sensitive funology used the sound allows user emotional effect and they prefer to intuitive and immediate motion and response of interactive funology. In other way, funology of fun in itself which is strong concept in original book diminishes in app book. Then users concentrate interactive factors like game structure. This results make that app books could be created by strength of original contents and advantage of funology. Therefore this makes us expect the possibility of reformatting effect with funology and we need to discuss the points of issue that there are considerations and limitations to successful app book for users.

Korea has suffered numerous casualties due to a lot of accidents caused by safety insufficiency in recent years. Therefore, safety education is more important than ever before, and 'how to educate with what contents' is an important subject. Especially, experience education is effective rather than theoretical education because of the nature of safety education. However, it is not easy to design and develop these safety education programs. There is not much opportunity to access first-aid training, which is a part of safety education, unless it is compulsory to learn through public institutions. As a result, program utilization on safety education in Korea is still insufficient to what it should be. With that taken into account, this study proposed an effective serious game with fun and immersion for medical first-aid education. To do this, we analyzed five medical games through 20 cases of first-aid applications and elicited five factors that enhance the usability of serious games. With an analysis of five medical games, we selected one game to borrow the game rules, and applied the elicited five elements in the forms of level-up structure, iterative learning, compensation outcomes, competition system, and information transfer. The proposed medical education functional games should have 1) a character that plays a role of a patient, 2) a narrative flow that shows the situation, 3) the user should judge the situation and induce first aid. 4) compensation, levels, and simple repetition should be designed, and 5) information should be shared with the others in the given community. The results of this study is believed to contribute to enhance the medical emergency education in Korea.

The video content platform, which is a social media, is used as a means of producing various contents with high immersion, ease of use, and low production conditions. However, existing social media-related studies were insufficient to examine differences in existing information attributes despite the differences in platform types. Therefore, this study intends to examine the relationship between existing media and social media information attributes. The research model was analyzed by surveying 213 video content users. As a result of the research model analysis, information playability, information timeliness, and information provider reliability had a significant effect on information usefulness. However, information vividness, information accuracy, information neutrality, and professionalism of information providers did not have a significant effect. Through this study, the difference between video content and existing media or social media was found, and it was found that a reliable information provider should provide pleasant content at the right time. In addition, through the understanding of the information processing process of video content, which is a key player in the growth of social media, we believe that it will be very helpful in producing quality content.

A Digilog Book is an augmented reality (AR) based next generation publication supporting both sentimental analog emotions and digitized multi-sensory feedbacks by combining a conventional printed book and digital contents. As a Digilog Book authoring software, ARtalet provides an intuitive authoring environment through 3D user interface in AR environment. In this paper, we suggest ARtalet authoring environment based trajectory editing method to generate and manipulate a movement path of an augmented 3D object on the Digilog Book. Specifically, the translation points of the 3D manipulation prop is examined to determine that the point is a proper control point of a trajectory. Then the interpolation using splines is conducted to reconstruct the trajectory with smoothed form. The dynamic score based selection method is also exploited to effectively select small and dense control points of the trajectory. In an experimental evaluation our method took the same time and generated a similar amount of errors as the usual approach, but reduced the number of control points needed by over 90%. The reduced number of control points can properly reconstruct a movement path and drastically decrease the number of control point selections required for movement path modification. For control manipulation, the task completion time was reduced and there was less hand movement needed than with conventional method. Our method can be applicable to drawing or curve editing method in immersive In-Situ AR based education, game, design, animation, simulation application domains.

The digital convergence looking for new ways to engage visitors by superimposing virtual content on projection over the real world captured media contents. This paper propose the Light ID based interactive 3D immersive exhibition things view using HMD AR technology. This approach does not required to add any additional infrastructure to be built-in to enable service and uses the installed Lighting or displays devices in the exhibit area. In this approach, the Light ID can be used as a Location Identifier and communication medium to access the content unlike the QR Tag which supports provide the download information through web interface. This utilize the advantages of camera based optical wireless communication (OWC) to receive the media content on smart device to deliver immersive 3D content visualization using AR. The proposed exhibition method is emulated on GALAXY S8 smart phone and the visual performance is evaluated for Jeonju Hanok Village. The experimental results shows that the proposed method can give immersive 3D view for exhibit things in real-time.

UCC, an abbreviation for User Created Contents, is not only a symbol of desire but also a product of creativity that a producer contains his or her subjective disposition. More and more UCC tend to have significantly increased in Web 2.0 environment. However, the research on the contents as a creative product has rarely been processed. It may be fairly said that this results in the indifference of researchers in the special field like the political contents since UCC is usually produced by amateurs. Producers' various desire is unlikely revealed, which leads to the flow of users into open media such as the Internet. It could also be available to represent the property, of plural visual language signs in a field. Moreover, UCC has the attribute of re-mediation in effective communication, so the differences between the semiotic properties in the Internet contents could be a significant material for researches. This could contribute to establish a theoretical system for the visual communication. Therefore, this study aims to analyse the signification of the political video UCC, . To develop this analysis, I apply Greimas' Generative Trajectory of Signification Theory to the text, or the UCC. He classifies it as three structures: deep structure, superficial structure, and discourse structure. As a result, the text shows meaningful contents delivering core political messages. In addition, this approach could exam that 'Obama Syndrome' in American recent presidential campaigns is caused by web 2.0 based on Internet campaigns including video UCC.

Virtual Reality(VR) is a new technology which makes humans communicate with computer. It allows the user to see, hear, feel and interact in a three-dimensional virtual world created graphically. In this paper, we introduced VR into psychotherapy area and developed VR system for the exposure therapy of acrophobia. Acrophobia is an abnormal fear of heights. Medications or cognitive-behavior methods have been mainly used as a treatment. Lately the virtual reality technology has been applied to that kind of anxiety disorders. A virtual environment provides patient with stimuli which arouses phobia, and exposing to that environment makes him having ability to over come the fear. In this study, the elevator stimulator that composed with a position sensor, head mount display, and audio system, is suggested. To illustrate the physiological difference between a person who has a feel of phobia and without phobia, heart rate was measured during experiment. And also measured a person's HR after the virtual reality training. In this study, we demonstrated the subjective effectiveness of virtual reality psychotherapy through the clinical experiment.

In recent year, graphic emoticons in MIM(Mobile Instant Messenger) play an important role not as a valuable communication methods, but as main business model for MIM service providers. Although the graphic emoticons in MIM are regarded as a commercial product, there has been little systematic research reflecting consumers' perspectives. In order to fill this theoretical and practice gap, the study is designed to explore the structural relationships among emoticon use motives, attitude, and purchasing intention to emoticons in context of MIM. The results showed that emoticon use motives in MIM were composed of two main factors, perceived usefulness and perceived enjoyment. And we also verified that both perceived usefulness and perceived enjoyment positively impact flow in communication with using emoticons and social influence. Lastly, flow and social influence were positively related to attitude toward using emoticons and attitude also was related to purchase intention to emoticons in MIM, positively. However, flow and social influence did not have a positive influence on purchase intention to emoticons directly. The implications and limitations of this study are also discussed.
