본 작품은 학생들의 캡스톤디자인 작품이다. 2019년 코로나 시대가 도래한 후, 사회 전반적으로 많은 변화가 일고 있는데, 특히 5인 이상 집합 금지 및 식당 영업시간 제한 조치 등으로 인하여 외식을 선호했던 가족이나 개인이 집콕하는 시간이 늘면서 홈쿡과 홈베이킹이 대세를 이루게 된 것이다. 본 아이디어는 스마트 기술이 가전에 적용되면서 요리에서도 스마트 기술이 필요하다는 생각에서 출발하였다. 기존의 레시피는 다양한 책과 동영상(유투브) 등으로 소개되기 때문에 요리 방법을 보면서 시간과 소스의 양을 정확히 지키기 어려웠다. 하지만 본 작품에서 소개된 스마트쿡은 자체에 타이머와 저울 기능을 부여함으로써, 요리에 필요한 타이머 기능과 미세 조절 가능한 레시피 소스를 과학적으로 요리할 수 있도록 설계되었다. 이러한 부가 기능을 가진 스마트쿡이 실제로 적용된다면 요리의 시간이 한층 더 재미있고 과학적이 될 것으로 판단된다.

Squat exercise is one of the free weight exercises that are recognized as important from a bio-mechanical point of view. It is an important exercise to train lower extremity muscles in daily activities or sports activities and to strengthen trunk and lower body strength. It is effective and accurate to use a variety of assistive devices to calibrate athletic posture with squat exercise supported interactive device. The issues of the structural analysis for design a foot plate for squat exercise is to model the behavior by simplifying the dynamic behavior. In this paper, the authors proposed a exercise system design method for the vertical load distribution and bio-mechanical signal process used for the squat exercise mechanism analysis, and based on these results, designed device can make the more safe and reliable free weight exercise. It is applied to system design through design method with kinematic dynamic, VR device and estimation model of exercise.

The rapid development of information technology has much influence on architectural design. Collaboration beyond time and space has been possible by networking the work environment and digital products. Thus, the virtual design studio on architectural design is getting more important than ever before. This research investigates a virtual design studio methodology for effective collaboration. The building design process and the communication model are studied and possible modes of design collaboration are defined. This paper proposes an internet-based Virtual Reality(VR) communication tool as well as new design methodology that we call the 'Hybrid Design Methodology'. We expect that this design methodology will dramatically increase design feedbacks, and thus results in better design alternatives. There are two issues involved in developing the collaborative virtual design studio: 1) an intuitive interface that presents collaborative relations, and 2) three-dimensional computer-mediated communication tool using sketch as a modeling method. Further research issues identified at the end of the research include developing algorithms that translate mapping images to polygons for the drafting phase in the design process.

In this study, we propose the design of Radial Basis Function Neural Network(RBFNN) classifier in order to classify between precipitation and non-precipitation echo. The characteristics of meteorological radar data is analyzed for classifying precipitation and non-precipitation echo. Input variables is selected as DZ, SDZ, VGZ, SPN, DZ_FR, VR by performing pre-processing of UF data based on the characteristics analysis and these are composed of training and test data. Finally, QC data being used in Korea Meteorological Administration is applied to compare with the performance results of proposed classifier.

This study intends to acquire objective models for basic quantitative analysis of pattern and space through image-recognition technique, and verify the effectiveness of such acquired models. Many experiments showed that the recognized result can be varied depending on the different viewpoints and the analysis based on the single-viewpoint images does not provide objectivity. The experiment using multi-viewpoint image models, which was attempted as an alternative for the disadvantages, showed the recognition similar to that of the actual model. Especially, images generated at laboratory using miniature model may be useful in comparing and understanding plural number of patterns. The models that have been acquired using such images may be hard to use in acquiring images for analyzing actual building patterns or indoor space, although they may be useful in pattern analysis using miniature model. The disadvantage, however, can be supplemented with panorama VR and C. G. simulation technique. Steady researches are required on the application of visual information to the image recognition principle and the model for quantitative analysis of pattern and space in addition to the research on the construction of the model that can be used in comparing and analyzing not only form and space but also miniature models.

Most previous studies, in general, related to housing needs have analyzed the data from self-administered survey or interview using questionnaire or simple 2D floor plan. This study was Intended to suggest how to increase the reliability and effectiveness of such survey methods in examining the residents' housing needs. In order to accomplish the purpose, the two kinds of surveys using Web based VR media and typical questionnaire were peformed. The same questions were used for these two surveys, and they included the furniture characteristics, use of each room, adjustment of room size, preferences for interior colors, preferred furniture in living room, space layout of floor plan, housing life style, and preference for housing characteristics. The answer differences between these two were analyzed. The subjects were 402 housewives who lived in apartment houses in Haeundae, Busan. Finding were as follows: first, the media method was more likely to be effective than typical questionnaire survey in explaining housing needs for the adjustment of room size in housing unit plan. Second, the media method was more realistic and reliable than the other in comprehending the needs for the interior colors. Last, the VR media tended to be more effective than the other in understanding the space layout of floor plan. This research sheds light on the utilization of visual instrument for the analysis of needs related to space use.

IMF 한파와 더불어 건설 시장 역시 침체되어 있는 되도 불구하고 사회 및 문화의 변화속도는 빨라지고 있으며 소비자들의 주택 선호도 역시 다양해지고 있다. 과거 정부주도의 주택 확대정책에 따른 획일화된 아파트의 양적 팽창은 이러한 빠른 변화와 다양화에 적응할 수 없는게 현실이며 또한 많은 문제점을 남기게 되었다. (중략)

근대 사회의 보편적인 건축의 언어를 창출하려던 모더니즘의 신화가 무너지고 난 후에, 새로운 보편적 건축양식을 찾아보려는 노력은 현재까지 계속되어오고 있으나 현대건축에서 공유할 수 있는 보편적 건축어휘는 부재한 상황이다. 현대의 건축가들은 각자의 건축적 언어체계를 만들어내려는 노력과 더불어 여러 방면의 건축적 실험을 통해 새로운 건축의 규범을 정의하려는 노력에도 경주하고 있다. (중략)

In these days, the importance of design becomes increasing and the design aspect that customers decide to purchase products such as television, mobile phone is more important than functional one. And the progress of virtual reality technology enables us to feel the reality from the virtual prototype as the real one. In this paper, we introduce the collaboration design review system consist of MEMPHIS, CORE. We can create a realistic virtual prototype more fastly, conveniently and efficiently using MEMPHIS and carry out the design review through collaboration using CORE. As a result of this study, it would be possible that decision making can be done effectively at early stage of the design process.

Consumer satisfaction and feelings with form play an essential role in determining the success of a product. However, contemporary industrial design processes typically employ designer driven, intuitive methods for generating and evaluating form concepts. This paper describes the implementation process of web based design support system that helps assess customer's feelings or sensibilities of forms created in each stages of design process. The present web based approach provides designers with fast and various feedbacks about their design in each stage by using assessment with object VR and web 3D as well as ordinary 2D images. Practical application for exterior design of electric vehicle was illustrated and the further refinement of the design support system was discussed.
