본 논문에서는 가상협업환경에서의 텔레프레센스를 제공하기 위하여 실사 기반 사용자 모습을 가상세계에 투영하여 가상객체와 함께 보여주는 사용자 미러링 기법을 제안한다. 가상협업환경 구축 시 널리 이용되는 $CAVE^{TM}-like$ 시스템과 같은 프로젝션 기반 가상환경에서는 스크린으로 투사되는 빛의 변화로 인하여 강건한 사용자 영역 정의가 쉽지 않다. 본 논문에서는 이와 같은 문제를 해결하기 위하여 적외선 반사 영상을 이용하여 사용자 영역을 정의하고 이 영역의 텍스처 정보를 칼라 카메라 영상을 통해 제공할 수 있도록 하였다. 제안 기법을 이용하면 가상환경 내에 존재하는 사용자를 상대측 가상세계에 미러링 하여 보여줄 수 있으므로 효과적인 텔레프레센스를 제공이 가능하다. 제안된 기법은 이화여자대학교 컴퓨터 그래픽스/가상현실 연구센터에 설치된 $CAVE^{TM}-like$ 시스템 상에서 실험하여 검증하였다.

디스플레이 미러링은 두 기기에 동일한 화면을 출력하는 기법으로, 작은 화면을 갖는 모바일 기기의 단점을 보완하기 위해 사용한다. 그래픽 기반의 디스플레이 미러링은 지연시간이 짧고 화면 품질의 저하가 없는 장점이 있다. 본 연구는 모바일 기기에서 추가적인 하드웨어 없이 수행이 가능한 그래픽 기반의 디스플레이 미러링을 제안한다.

What should a therapist do if the patient has lost the ability to speak in sessions? How should the therapist understand and approach this 'deadly silence'? Psychosomatic patients have poor ability to mentalize their experience, so they create a 'shunt' from emotional experience to body bypassing symbolic sphere. This makes psychosomatic patients vulnerable to expressing their emotions in words. With the case vignette 'When words are unspeakable: a bridge beyond the silence' written by Wirth in a book "From soma to symbol" we observe how psychosomatic pathology arises, from inappropriate mirroring and poor containment; and how this escalates into a vicious cycle of sin and punishment in the patient's conscience. This conscience scenario imprisons a talented and creative mind in a dark, silent place, wherein symbols and words are forbidden. This seemingly impossible task of providing silent patients with a 'talking cure' finds breakthrough with containment, and transformative thinking using therapists' reveries.

스마트 모바일 기기의 발전으로 고성능, 고효율, 사용성이 급격하게 증가하고 있다, 또한 개인의 용도를 확장한 교육 분야 및 기타 산업분야에 전반적으로 사용되고 있다. 하지만 산업 및 교육 측면에서는 스마트 기기의 화면이 너무 작어서 활용성 및 교육적인 면에서 제약으로 대두되고 있다. 이에 본 연구에서는 스마트 모바일 기기의 화면을 실시간 HD 무선통신을 통한 대형 전자칠판으로 전달하고 또한 대형 전자칠판의 터치 데이터를 스마트 기기에 전달하여 대형 전자칠판에서 스마트폰 기능을 사용가능하게 하는 연구이다.

The Israeli military's track record boasts victories in four Middle East wars and numerous counter-terrorism battles. This can be attributed to the implementation of a flexible defense acquisition system, allowing for the rapid acquisition of cutting-edge weaponry in response to ever-changing enemy vulnerabilities. If Korea were to adopt the defense acquisition system employed by the Israeli Defense Forces (IDF) it has the potential to transform into a small but strong country, mirroring the accomplishments of the IDF.

Is there my relationship between a port information system and a port type? This paper aims to define its relationship through a study on the port types of advanced countries and their information systems. In terms of port ownership and its governing body, the port type can be divided into 4 types: state-run, public corporation, local government-run, and private ownership. According to the port type, the major activities of ports are different. In the case of a state-run and local government-run port, they put emphasis on the function of administration, but a public corporation and private ownership stress the importance of customer services. The study results of the mutual relationship of a port type and an information system show that the state-run and local government-run ports have a good administration-oriented system, and public corporation and privatized ports have an excellent customer-oriented community system and e-business system. The differences in the information system by port type provide an important suggestion to the improvement of information system of Busan Port Authority. As Busan port has been transformed from a state-run type to a public corporation, a new port information system has to be followed. Accordingly, this study has suggested a three-stage development plan: The first is a mirroring stage of stabilizing the port management, the second is a cooperation stage of enhancing customer services through the establishment of a community system, and the third is an e-business stage of developing a profit system in order to create value added.

This study aims to explore the difficulties of Korean dance instructors targeting senior people and extends the difficulties found to developing PBL problems applicable to the instructors' education. To address the goal, this author employed an open-ended questionnaire consisting of four questions and 1:1 interview and collected data. According to the study results, total nine subfactors were drawn from four difficulties associated with student management, the curriculum, performances, and class environment. First, about difficulties related to student management, 'conflicts between students' and 'demand for personalized class' were explored. Second, regarding difficulties about the curriculum, 'refusal against new teaching methods' and 'level difference according to the ability of acquisition' were explored. Third, concerning difficulties related to having performances, 'lack of time for practicing', 'needs to achieve excellent performances', and 'the administration of organizations in charge' were explored. Fourth, about difficulties associated with class environment, 'environment in general' and 'spatial environment' were explored. Also, based on the difficulties explored from dance instructors for senior people, this researcher has developed four PBL problems through community dance for harmony, joint choreography-based creative dance, playful dance allowing role division, and mirroring-based dance.

The technical progress of wireless communication in an information-oriented society is heading for the wireless internet service. Handphone is limited in a low capacity memory, size of screen, wireless internet. But it can do service in mobile, nontheless of the time, space. This paper says that online studying in wire internet is capable of servicing in mobile environment. The way of SMS transmission in the agency is linked in the SMS agency, but the way of SMS exclusive modem does service in linking with personal computer. This paper says that the SMS service is possible with SMS exclusive modem, mirroring of the client demand in database.

최근의 웹을 기반으로 한 소셜 네트워크 서비스의 발전은 사회관계 형성 서비스를 넘어 광고 마케팅 및 SNS 오픈마켓 등의 상업적 이용으로까지 사용되고 있으며 Facebook Live와 같은 개인방송의 영역까지 확장되고 있다. 인터넷을 통한 온라인상의 사회관계는 노화와 질환으로 외출이 어려운 노년층에게 지역사회 및 친구들과의 의사소통을 가능하게 할 뿐만 아니라 인터넷을 통한 정보 활용으로 생활의 질을 향상시키고, 노후를 즐길 수 있는 방법을 찾는 데 도움을 줄 수 있다고 알려져 있다. 하지만 대부분의 웹서비스는 복잡한 사용자 인터페이스를 제공하고 있으며 익숙하지 않은 기기를 사용하는 것은 노년층에게 쉽지 않기 때문에 노년층은 제한된 콘텐츠만을 제공받게 되어 정보화 사회에서 소외될 가능성이 있다. 이에 본 논문에서는 웹 접근성을 향상시킨 소셜 콘텐츠 서비스 Photo Alive! Demo EasyFace를 소개한다. 또한 노년층이 다루기 어려웠던 키보드와 마우스를 벗어나 새로운 조작 기기들로 웹 서비스를 이용할 수 있도록 구현하였다. MINIX Remote Control, Mirroring, EasyFace Control Application 세 가지의 조작기기 작동 방법을 구현하여 노년층에 맞춤화 된 새로운 사용자 인터페이스를 제안하고자 한다.

If the System is downed by computer or disasters, it can have a bad influence on the reliability of the corporation and business continuity because all companies are computerized. Accordingly, interest on the business continuity without the loss of data in the corporate is increasing. In this paper, system faults have been defined as physical faults and logical faults and CDP solution using Flash SSD has been proposed for enhancing IOPS which is needed for realtime-backup. In order to measure IOPS performance of the CDP using Flash SSD, we constructed an experimental system. From the results we can see that IOPS performance of CDP using Flash SSD is about 50 times more effective than that of the S-ATA.
