본 연구는 비례 추론에서 형식적 절차의 기계적 사용에 대한 비판과 이에 대한 대안으로 제시되는 시각적 모델의 사용에 대한 연구를 바탕으로 비례 추론 수업에서 시각적 모델의 활용 가능성을 탐색했다. 이를 위해 6학년 2학기 비례식과 비례배분 단원을 비표, 이중수직선, 이중테이프 모델을 활용한 수업으로 구성하여 한 학급에 적용하였다. 그 결과 시각적 모델이 비례의 의미를 이해하고 비의 성질 및 비례식의 성질을 발견하는 데, 그리고 비례식 문제 및 비례배분 문제를 해결하는 데 중요한 역할을 할 수 있음을 알 수 있었다. 또한 이러한 시각적 모델을 활용하는 데 학생들이 겪는 어려움과 이를 지도할 때 유의할 점이 있음을 확인하였다. 이를 통해 시각적 모델을 적극적으로 활용한 교과서 개발 및 비례 추론 수업에 대한 지도 방안을 마련하는 데 시사점을 제공할 수 있기를 기대한다.

This study is about the application of visual structure and presentation of film as one of new methods for design of sequential landscape. The primary objective of the study is to present the basis of applicable and reasonable D니. In applying components of film to DSL, if it is compared with sequential landscape, the film is collection of shots while sequential landscape is accumulation of sceneries. Film and sequential landscape give us a whole meaning different from the meaning itself of a shot or scenery in its experience. The study build a tentative technique of DSL which has the following stages : 1) Goal setting and making out a scenario 2) Analysis and investigation 3) Selection process of definite form 4) Drawing up conti., sketch and notes, It is expected that the technique presented in this study could be a basis for further study of DSL.

시작장애인은 일상생활에서 시각저하로 인하여 색상, 지폐 금액 확인, 온도 판별 등의 불편을 겪는다. 그리하여 시각장애인을 도와주기 위한, 광학 카메라와 열화상 카메라를 이용한 시스템을 제안한다. 광학카메라는 특징 추출을 이용하여 색상 판별, 지폐 금액 확인하며, 온도 판별을 위해서 열화상 카메라를 이용한다. 버튼을 이용하여 색상, 지폐, 온도 모드를 선택하면, 해당 정보를 스피커를 통하여 음성으로 알려준다. 색상은 16가지, 지폐는 4가지, 온도는 4단계로 구분할 수 있으며, 각기 정확도는 90%이다. 향후 입력 영상 블록화, 머신러닝, 열화상 카메라 상위 버전을 통해 정확도를 개선할 수 있다. 또한, 휴대하기 편하게 지팡이에 부착하여 시각 장애인들이 더 편리하게 사용 할 수 있도록 개선 예정이다.

Purpose: This study was a qualitative research using focus group interviews to collect data on the health care providers' perceptions of physical function in older adults with arthroplasty from hip fracture. Methods: A total of 12 subjects participated in this study. In order to conduct focus group interviews, structured manuscript, field notes, visual recording, and debriefing notes were referred and thematic analysis was used in analysis phase. Results: The six themes were raised: 'burdensome client', 'health care providers' perception of functional decline in older adults after surgery', 'health care providers' perception of caregiver', 'medical environment perceived as affecting physical function', 'crucial components perceived as encouraging functional restoration', and 'difficulty of pain management' with 18 subthemes. Conclusion: Healthcare providers perceived functional decline of elderly after arthroplasty and identified points facilitating or disturbing physical function Moreover, various perspectives on pain management related to physical function were represented.

최근 BCI(Brain Computer Interface) 기술의 발전과 함께 보급형 BCI 장치를 활용한 게임연구가 활발히 진행되고 있다. BCI 게임은 대부분 연구를 위한 실험적인 체험용 콘텐츠 형태로 개발되어 왔으며, 명령 패러다임에 있어서 BCI 게임 명령에 적합한 뇌파를 유도하는 방법에 대한 연구는 미흡하다. 본 연구에서는 음악의 리듬을 시청각적으로 표현하는 새로운 플레이 요소를 제공하는 BCI 리듬게임과 음악의 템포와 뇌파를 동기화 시켜 다양한 형태의 시청각 피드백을 생성하는 방법을 제안한다. 제안방법은 실험을 통해 게임조작에 필요로 하는 뇌파를 유도하여 게임점수를 향상시킬 수 있음을 확인하였다.

Objective: Optochiasmatic cavernoma is an extremely rare cerebral lesion. They account for approximately 1% of all cavernomas of the central nervous system. Reports on this pathology are limited. Abrupt visual deterioration is a common symptom of the disease. Treatment strategy and visual outcomes after different treatment approaches remain a subject for discussion. Methods: Patients operated in a period 2005-2021 were analyzed in this study. All patients preoperatively underwent computed tomography (CT) scan, CT-angiography, and magnetic resonance imaging (MRI). Visual function of the patients was assessed pre-op, post-op and at the follow-up. Duration of visual dysfunction was noted as well. Surgical details were also extracted from medical notes. All patients were followed up, and control MRI was performed one month after operation. We assessed surgical series of optochiasmatic cavernomas published for last 10 years. Further comparative analysis with our data was performed. Results: Five patients were included into this study. There were four men and one woman. Mean age comprised 33.8 years (range 20-48 years). Most patients were admitted to our hospital due to visual disturbances (80%). Visual function improved in four patients. Visual function was unchanged in one patient, lacking visual distur-bancies pre-op. Complication developed in one patient. Conclusions: Optochiasmatic cavernomas are encountered extremely rare. Despite the use of contemporary diagnostic options, differential diagnosis remains challenging. Full diagnostic work-up is mandatory. After the diagnosis is made, surgical treatment should be considered first. Total microsurgical or endoscopic transsphenoidal removal of the optochiasmatic cavernoma is a relatively safe and effective treatment method facilitating improvement of visual function.

In this Paper, an Audio-Visual Teaching aid (AVTA) for use in a classroom and with Internet is presented. A system, which was designed and tested, consists of a wireless Microphone system, Text to Speech conversion Software, Noise filtering circuit and a Computer. An IBM compatible PC with sound card and Network Interface card and a Web browser and a voice and text messenger service were used to provide slightly delayed text and also voice over the internet for remote teaming, while providing scrolling text from a real time lecture in a classroom. The motivation for design of this system, was to aid Korean students who may have difficulty in listening comprehension while have, fairly good reading ability of text. This application of this system is twofold. On one hand it will help the students in a class to view and listen to a lecture, and on the other hand, it will serve as a vehicle for remote access (audio and text) for a classroom lecture. The project provides a simple and low cost solution to remote learning and also allows a student to have access to classroom in emergency situations when the student, can not attend a class. In addition, such system allows the student in capturing a teacher's lecture in audio and text form, without the need to be present in class or having to take many notes. This system will therefore help students in many ways.

To enable AI(artificial intelligence) to realize visual emotions, it attempts to create music centered on color, an element that causes emotions in paintings. Traditional image-based music production studies have a limitation in playing notes that are unrelated to the picture because of the absence of musical elements. In this paper, we propose a new algorithm to set the group of music through the average color of the picture, and to produce music after adding diatonic code progression and deleting sound using median value. And the results obtained through the proposed algorithm were analyzed.

Digital information society shows a variety of contents of cross-categorial digital media in their inner or outer forms and concepts of the artistic aspects. In order to cope with such a complicated, unexpected trend in digital media and its industry, a new approach in the design process needs to be developed and adjusted with the new equipment of the creativity-thinking process of 'the Multi-Sensory Device (MSD),' 'the Multi-Dimensional Device (MDD),' and 'the Storytelling Device (SD)' in the Prism Effect-based Creativity-Thinking Process (PECTP). The PECTP is in principle designed to practically work with the four distinct techniques: 1) Physical Activity, 2) Linguistic Activity, 3) Visual Activity, and 4) Complex Activity. Consequently, this thesis notes that the nature of the cross-categorial design contents is necessarily non-directional since the creativity power inside the Prism Effect results in openness and diversity.
