As sewerage systems have obsolete, as quality and service level standards increase, and as rain characteristics change, the sewerage utility authorities are challenged to develop cost recovery strategies that assure financial sustainability. In this study, we conducted scenario analysis to examine the effect of three alternatives of partial or full sewerage cost recovery in Seoul during 2014-30 periods. It turned out that the alternative 1 is optimal and recommended. According to alternative 1, we had better increase annually sewerage fee by 14.8% until 2020 and thereafter apply only the inflation rate in setting sewerage fee. It would gradually decrease the deficit after 2019. The accumulated deficit of 13 billion Won in 2030 was estimated.We expect that this kind of analysis may provide useful informations to help sewage utility staffs, decision makers, and regulatory authorities understand, develop and implement ultimate full cost recovery strategy for many municipalities.

Play is the basics of cognitive, physical, and emotional development of infants, and especially pretend play is very important in the aspect that it enhances imagination and expression of infants by drawing making up free imaginative story and physical expressions. On the other hand, on the effect of structural reality of toys used in pretend play on pretend play of infants, it is predominant that as the structure of the toy becomes higher, the pretend play is promoted. When it is connected to the environmental aspect of play of infants, it can be inferred that infants may be easily immersed in imaginative world using the fact that they are placed in play environment that provides detailed symbols about certain subjects. Also, as a technique to provide such environment, chroma key that realizes virtual learning environment may be used. Chroma key, one of image composition technologies, can be an effective means of enhancing curiosity, immersion, and expression skills of play activities by providing infants with realistic spatial background. Furthermore, sense of space is an essential basic ability to understand, interpret, and evaluate surrounding world, and virtual reality may help infants overcome physical and economic constraints of the existing child education institutes and raise their sense of space in safe environment. In addition, in order to use the chroma key technology effectively, it’s necessary to make infants understand about the chroma key and specialize teaching methods along with appropriate education plan.

QR code has been widely used for Augmented Reality games as well as for many commercial applications. However, its usage was limited because it is difficult to enable tangible interactions through which users may change 3D models or animations. Markers, by blocking designated regions, may be recognized as different patterns allowing for tangible user interactions. Unlike markers, it is difficult to alter QR code patterns because QR code contains error correction patterns. In most cases, altered patterns cannot be recognized. Our goal was to enable QR code based interactions for Augmented Reality games. By performing research and experiments, we discovered a mechanism for altering QR code to change the text string that the QR code represents. In this paper, we introduced a QR code alteration prototype that is based on composition of partial QR codes by using transparent film overlays. We endowed tangible interaction capability to QR code for Augmented Reality games.

Location based service and AR(Augmented Reality) techniques have been one of the most important areas in current computer games and mobile application. This paper presents GPU(Graphics Process Unit) based image recognition system for outdoor games and mobile application. In learning stage, we extract features from input image sequence and convert them into meta information in database. User captures then a query image that is sent to GPU based server system. The proposed system build a descriptor codebook using BRISK and SURF descriptors, and employs codebook with re-ranking information based on homography.

The inauguration of the collective Reality and Utterance (Hyŏnsil kwa Parŏn) in 1979 and 1980 marked a watershed moment in Korean art. This is not only be-cause the collective gave birth to the politically-engaged art movement that would come to be labeled “Minjung Art” by the middle of the 80s, but also because it enthusiastically embraced a wide range of images from the urban culture. With a special focus on the members’ early work, my research explores an issue largely neglected in the dominant narrative of Minjung art as a form of activism against the authoritarian Korean government during the 80s. The issue is what was at stake in Reality and Utterance’s exploration of contemporary urban visual culture. The aim of this essay is to recognize the engagement with the urban visual culture as central to the group’s early project and to consider it at some distance from the anti-urban and anti-mass culture perspective which was endorsed by the Minjung narrative. Focusing on members’ turn to urban visual culture, this essay instead argues that this turn was by no means merely a means to making art as social cri-tique, but more importantly, it was an experiment with the shared image world, as opposed to the rarefid visual vocabularies of abstract modernism. Visual produc-tions such as advertisements, billboards, posters, and kitsch paintings, which come from outside the narrow confins of fin art, were definitly ominous signs of the colonization of everyday life in the capitalist city, but at the same time they were an-ticipated to be a catalyst for redefiningKorean art in a more communicative, acces-sible, and democratized way. In this regard, in the early 1980s—in particular 1980 and 1982—the members’ gesture oscillated between critique and embrace, which allowed the group to occupy a unique domain in the realm of Korean art production.

The purposes of this study were to analyze the effects of the experience realms (entertainment, educational, escapist, and esthetic) of augmented fashion reality applications on consumers' pleasure, satisfaction, intention of reuse, and purchase intention. This study is based on the survey subjecting those who have an iPhone. A total of 207 questionnaires were processed in analysis. Descriptive analysis, frequency analysis, reliability analysis and regression analysis were conducted using SPSS ver. 18.0. The results are as follows. First, entertainment and esthetic experience positively influenced consumers' pleasure. Second, entertainment, educational and esthetic experience positively influenced satisfaction. Third, pleasure positively affected satisfaction. Forth, both pleasure and satisfaction positively influenced intention of reuse and purchase intention. Fifth, there were significant differences in the effects of the experience realms of augmented fashion reality applications on pleasure, satisfaction, intention of reuse, and purchase intention by gender. In conclusion, pleasure and satisfaction that influence reuse intention and purchase intention were influenced by the experience realms. When consumers feel satisfaction and pleasure in experience realms of augmented fashion reality applications, they are more likely to reuse of an augmented reality fashion application, and to purchase the products consumers were implementing an augmented reality fashion application for.

This paper is aimed at designing learning contents by applying augmented reality, as a plan to improve learning effect of learners who will study cultural properties. Learning cultural assets does not contain educational media which is able to be used for current learning. Even if is has the media, they are not fitting for the current educational situation, and most of them are simple. Insufficiency of educational media will make learners, who are interested in cultural properties and who are about to freshly learn cultural properties, far away from their desires to lean. Learning cultural properties is appropriate for a learning type to apply augmented reality. Accordingly, the author is aiming at developing educational media by applying augmented reality to learning cultural assets. In order to apply augmented reality, this paper examines concept of augmented reality and its application cases, accelerated learning factors and efficiency through the relevant pre-studies and development cases of educational application, and methods by which augmented reality is used for learning media. Based on these studies, this paper applied a learning theory stated in the pre-study, and designed learning contents by using augmented reality producing library. By means of the augmented reality based cultural properties learning contents, this paper plans to help learners who will study cultural properties and the relevant education, and to be a reference for designing learning contents applying augmented reality in the future.

Augmented reality is a state-of-the-art technology which presents auxiliary information by synthesizing real world scene with synthetic objects. Some augmented reality applications are commercially available according to the advance of mobile device capability. They combine strong points of "mobility" of mobile devices and augmented reality technology. Mobile games based on augmented reality technology are expected to become widespread in the near future. Therefore, mobile augmented reality technology is crucial for mobile games such as board games and so on. This paper analyzes the research trend of mobile augmented reality and presents some latest research results. Based on this analysis, future directions for mobile augmented reality are given.

This writing had research subject as Zhang Yang's movies titled <Getting Home(落葉歸根)>(2007) and <Full Circle (飛越老人 院)>(2012). Two pieces of movies are roughly distinguished from the existing movies in a sense of having commercially consumed a social issue, which is caused by migrant workers and aging, with the use of road-movie genre. This study was progressed a research with paying attention to this point. First, it considered the process that socially underprivileged people such as migrant workers proceed with being included in the mainstream narrative. It clarified that the combination of road movie and comedy is proceeding with solidifying position as one new trend while illuminating the process that migrant workers, who had been addressed realistically, are divided into a character of comedy and are again mixed with road movie. Second, a gap could be confirmed to be created between journey and reality shown in a movie due to the combination of road movie and comedy. And it examined how socially underprivileged people were commercially played a variation to be applied. At the same time, it could confirm that there is reality outside journey in a sense that therapy of being mobilized by family love is proposed as solution rather than complaining about and reflecting on reality with which socially underprivileged people are faced.

This paper explores rich and complex implications of Marcel Duchamp's Mile of String which he created for “First Papers of Surrealism,” the Surrealist international exhibition in New York in 1942. Part of a larger project devoted to investigating Duchamp's role in Surrealist exhibitions and his relation to the avant-garde group, this paper focuses on Duchamp's exhibition installation in the 1942 show. Under the title of “générateur-arbitre” Duchamp played an important role as installation and exhibition designer in a series of major Surrealist exhibitions in the 1930's-1960's. The “First Papers of Surrealism” was held by Surrealists who exiled in New York during World War I, and Duchamp created a labyrinthine installation of string for the exhibition, which physically blocked the spectator and optically hindered his or her contemplative view. Unraveling the intricately related meanings of Mile of String as an independent work of art and an installation for a specific exhibition, I examine the work on two levels: frst, how the work was situated in the context of Duchamp's oeuvre, particularly his earlier work employing string or thread; second, how and in what way the installation rendered a critique on Surrealism as a group and an avant-garde movement. More specifically, by exploring the concepts of ‘pataphysics’ and voluntary ‘nomadism’ implicated in Duchamp's work, I suggest that his Mile of String asserted a critical stance against nationalism and collective identity of Surrealism and manifested a radical individualism founded upon what he called the spirit of ‘expatriation.’

◉ 목적 : 본 연구는 가상현실 프로그램이 운동성 저하아동의 운동성, 주의집중력에 미치는 효과를 알아보기 위한 것이다. ◉ 연구방법 : BOTMP II(Bruininks-Oserstsky Test of Motor Proficiency II)와 활동성평정척도(Werry-Weiss-Perter’s Activity Rating Scale ;WWPARS ;이하 WWP) 검사를 통하여 운동성의 결함, 주의집중력 결함을 가진 2명의 아동을 대상으로 부모의 동의를 얻어 5주 동안 A아동 6회, B아동 8회에 걸친 가상현실 프로그램을 실시하였다. 아동마다 연구자 2명씩 개입하여 약 50분씩(Wii-fit, Wii-sports resort) 실시하였고, 초기 평가 후 각 6, 8회에 걸친 연구를 진행하여, 마지막 차에 최종평가를 실시하였다. 최종평가는 BOTMP II, 활동성평정척도(WWP)를 사용하였다. ◉ 결과 : 각 아동마다 BOTMP II, 활동성평정척도(WWP) 평가결과 A 아동은 BOTMP II, 활성평정척도(WWP) 모두 긍정적 효과가 있었다. A아동은 BOTMP II 결과 총점 63점에서 71점으로 증가하여 운동성이 향상되었고, 활동성평정척도(WWP) 검사결과 총점 11점에서 6점으로 감소하여 집중력이 향상되었다. B아동은 BOTMP II 결과 총점 52점에서 55점으로 증가하여 운동성이 향상되었고, 활성평정척도(WWP) 검사결과 총점 16점에서 19점으로 점수가 증가하여 집중력이 향상되지 못했다. ◉ 결론 : 가상현실 프로그램이 운동성과 주의집중력에 문제를 가진 아동에게 적용되었을 때 운동성을 향상시키고, 주의집중력에도 영향을 미치는 것으로 나타났다. 이러한 결과를 기초로 대상자들의 수를 늘리고 장기간에 걸쳐 아동의 변화를 확인할 수 있는 가상현실 프로그램 연구가 지속적으로 필요하다고 사료된다.

모바일 기술들이 발전함에 따라 발전된 모바일 기기들이 나오고, 그에 따른 여러 모바일 관련 분야의 기술들이 발전해가고 있다. 이런 모바일 기기들이 많이 나오고 있는 지금, 많은 사람들이 모바일 기기를 이용하는 시간이 늘어남에 따라 휴식시간에도 모바일 기기를 이용한 즐거움을 찾는 사람들이 늘어나고 있다. 그러면서 모바일 기기의 휴대성과 편리성을 이용하여 기존 컴퓨터로는 휴대하며 이용하기 불편했던 많은 증강현실 게임 기술들이 나오고 있다. 하지만 현재까지 나오고 있는 증강현실 게임들을 보면 미리 마커가 설치된 곳에서만 이용이 가능하거나, 모바일 기기가 인식할 수 있는 특징 점을 갖고 있는 장소에서만의 이용이 가능했다. 또한 GPS를 이용한 증강현실 게임의 경우 GPS상의 오차로 인한 약간의 불편함들이 존재했다. 본 논문에서는 모바일 기기에서 레이저 포인터를 이용한 증강현실 게임을 제시하며 앞서 살펴본 봐와 같은 기존 모바일 증강현실 게임들의 문제점들을 해결하고, 모바일 기기에 맞게 휴대성이 높으며 편리하고, 다양한 곳을 이동해 가며 할 수 있는 새로운 방식의 증강현실 게임을 제시한다.

모바일 컴퓨팅 분야에서 네트워크와 하드웨어의 발전은 디지털 지리공간 및 컴퓨터 지도학의 급속한 발전을 이끌고 있으며, 스마트폰 환경과 공간정보의 상호 작용 측면에서 증강현실(Augmented Reality)은 지도학을 비롯한 관련 학문 분야에서 새로운 연구 주제로 등장하고 있다. 이와 관련하여 본 연구는 증강현실의 일반적 개념과 접근 방법을 바탕으로 지리공간 속에서의 증강현실을 재해석하고 이를 토대로 지리공간정보의 교육적 활용성의 탐색과 관련 콘텐츠의 개발을 연구 목적으로 한다. 이를 위해 본 연구에서는 증강현실의 가장 기초적 단계인 큐알 코드(QR code)를 활용하여 지역 조사 및 답사를 위한 증강현실의 사례와 GIS에서 변환된 3차원 이미지가 마커기반의 증강 현실을 통해서 구현되는 사례를 제시하고자 한다. 또한 본 연구에서는 이러한 마커 기반 큐알 코드와의 연계를 통해서 기존의 종이 지도 기반의 실내 조사 방법과 더불어 지리조사법의 효율성을 높혀 줄 수 있는 장점을 제시하고자 한다. 이러한 연구 결과는 증강현실에 기반한 큐알 코드의 자발적 지리정보 활용 증대에 기여할 수 있을 뿐만 아니라 전통적인 종이 지도에서 나타나는 정보의 가시성, 사실성, 중첩으로 인한 해석의 어려움 등의 지도 가독성의 문제점을 해소하는데 기여할 것으로 예상한다.

This research aims to demonstrate the sociocultural significance of architectural journals produced in the 1970s during which a fundamental reconsideration of architectural discipline has been made. To this end, we established a method of analysis adapted to the characteristics of architectural journals of that period. In this formulation, the relative autonomy of architectural journal with regard to various actors and institutions involved in its production emerged as a major criterion for the analysis of a journal. From this methodological reflection, we analyzed two French architectural journals, AMC published between 1973 and 1981 and l’Architecture d'Aujourd'hui between 1974 and 1977, which were produced both in close relation with parisian architectural schools (UPA) in the context of reestablishment of architectural education and beginning of architectural research in France after the events of May 1968. If these journals reflected and strengthened the architectural reality and especially the social network of their protagonists, it is equally important to note that they have transformed it into cultural network, and this by the mechanism proper to their preparation and their textual organization.

예이츠는 전통적인 시극이나 동시대의 사실주의적인 극과는 또 다른 극을 창조하였다. 예이츠의 극은 아리스토텔레스의 극 이론을 거부한 특유의 극작법 때문에 동시대 작가들의 작품과는 다르게 보아야 한다. 그의 극 『그림자 어른거리는 바다』를 통해 예이츠는 관객에게 장엄한 무아경을 주려했다. 이 논문은 예이츠가 드라마틱한 형식, 즉, 시, 신비로운 분위기, 그리고 두 주인공 포겔과 덱토라의 시적 언어를 통해 그런 효과를 어떻게 달성하는지를 밝힌다.

목적 : 본 연구는 가상현실 게임을 이용한 훈련이 뇌졸중 환자의 기능회복에 미치는 영향을 알아보고자 실시되었다. 연구방법 : 연구대상은 편마비 환자 24명으로 전통적 재활 치료를 받은 대조군과 이와 더불어 가상현실 게임을 추가로 훈련한 실험군에 각각 12명씩 무작위로 나누어 총 16 주간 연구를 실시하였다. 대상자의 기능회복을 알아보기 위해 상지기능, 균형능력, 시·지각 능력, 삶의 질을 훈련 전과 훈련 6주후, 훈련 12주후, 훈련종료 4주후 추적 조사를 통해 측정하여 분석하였다. 결과 : 두 집단 간 차이를 분석한 결과 균형능력, 시·지각능력과 삶의 질의 영역에서 유의한 차이를 보였다. 실험군은 상지기능, 균형능력, 시·지각능력, 삶의 질의 모든 영역에서 유의한 차이를 보였으며, 대조군은 상지기능과 균형능력, 시·지각능력에서 유의한 차이를 보였다. 결론 : 뇌졸중 환자를 대상으로 가상현실 게임을 이용하여 훈련한 결과 균형능력, 시·지각능력, 삶의 질 영역에서 두 집단 간의 차이를 보였으며, 실험군에서 대조군보다 더 많은 영역에서 유의한 기능회복을 보였다. 본 연구를 통하여 뇌졸중 환자를 대상으로한 가상현실 게임을 이용한 훈련이 기능회복에 미치는 영향을 제시하였으며, 앞으로의 연구에서는 많은 수의 뇌졸중 환자를 대상으로 치료초기부터 함께 가상현실 훈련을 실시하여 좀 더 많은 정보를 수집 한 후 가상현실 게임을 이용한 뇌졸중 환자의 기능회복을 위한 올바른 프로토콜을 제시하여야 할 것이다.

목적 : 본 연구는 만성 요통 클라이언트의 건강관리 방법으로서 가상현실공간훈련이 신체적 측면에서 균형 능력, 심리적 측면에서 신체적 자기효능감과 생활만족도, 그리고 통증에 미치는 영향을 알아보고자 하였다. 연구방법 : 연구자는 균형 능력에 미치는 영향을 회기별로 알아보기 위하여 개별실험 연구방법을 사용하였고, 균형능력, 신체적 자기효능감, 생활만족도, 통증의 훈련 전과 후에 변화를 비교하기 위하여 사전 사후 집단실험 연구방법을 사용하였다. 연구에 참여한 대상자는 총 8명이었고, 연구대상자는 매회기 Nintendo Wii Sports 프로그램에서 세 개의 활동을 스스로 선택하여 운동하였으며, 1회기 총 운동 시간은 45분이었고, 1주일에 3회 수행하였다. 평가자는 기초선에서 클라이언트의 균형 능력과 통증을 측정하였고, 치료선에서 매회기 통증을 훈련 전에, 균형 능력을 훈련 종료 후에 측정하였다. 또한 평가자는 신체적 자기효능감과 생활만족도를 기초선 시작 전과 치료선 종료 후에 측정하였다. 결과 : 만성 요통 클라이언트의 균형 능력은 연구 대상자 두 명의 오른발 서기를 제외하고 치료선에서 기초선에 비하여 유지되거나 향상되었다. 훈련 전후 비교 시 신체적 자기효능감과 생활만족도는 통계학적으로 유의하게 증가하였으나, 통증지수의 유의한 감소는 없었다. 결론 : 본 연구는 Nintendo Wii Sports가 만성 요통 클라이언트의 균형 능력, 신체적 자기효능감, 생활만족도를 유지 혹은 개선시키기 위한 새로운 건강관리 방법으로서 사용될 수 있는 가능성을 제시하였다.
