Purpose: This study aimed to analyze the visual and spatial elements of the gait of a stroke patient who had diverse ankle weight loads applied, according to weight changes. Methods: The subject was a 57-year-old stroke patient diagnosed and hospitalized with a left intracerebral hemorrhage. A weight equivalent to 0%, 1%, and 2% of his body weight was applied to the area 5cm upward from the ankle using a Velcro strap. He was then trained on a treadmill, receiving a six-minute walk test to evaluate his gait ability. A gait analyzer was used to collect visual and spatial elements, such as gait distance, gait velocity, cadence, step length, stride length, and swing phase, according to a weight load equivalent to 0%, 1%, and 2% of his body weight. Results: According to the results of applying 0%, 1%, and 2% of his body weight on the ankle, except for gait velocity, his gait distance, cadence, step length, stride length, and swing phase were higher when 1% of his body weight was applied compared to 0% or 2% of his body weight. Conclusion: Applying a weight equivalent to 1% of the body weight to the ankle positively affected the visual and spatial element of the gait and heightened the efficiency of exercise during treadmill training, a gait-training tool generally used for stroke patients. However, the result is difficult to generalize because the number of subjects was small with only one subject.

The purpose of this study is to grope for plan methods through analyzing preferences on expression methods of materials for visual differentiation in hosing space. The results are as follows : First, we could know that finish material is the important element to make differential design in housing space. It is a effective method to use the color and material of finish materials. Second, we could find they preferred woods in materials and Y color, N9.5, bright and light in colors through grasping preference about types in material elements. The preferred texture is soft and the preferred patterns are solid and geometry. Third, it is a good method to mix materials which give us different season feeling, and to mix colors which are different tones to lead the differential design by materials in housing space. In case texture and patterns, what we mix similar things is the effective method. Fourth, preference of the expression method is manifested differently depending on the selected elements. so when we plan the housing, we have to consider that. lastly, I think this study will be a basic data on a study to differentiate the design of the residential space.

Recently, improvement of the quality of urban riverscape environment has been emphasized not only by landscape architectural field but also by various professionals in planning and ecology. Regarding to this current movement, the aim of this paper is to highlight major visual elements of riverscape axis as a case study of Shinchon River in Taegu City to suggest some basic guidelines for arranging riverscape in urban area. The study was mainly based on Repertory Grid Development method which was developed in Japan. The method is consist of three steps such as decision of element landscape in study area for slide photos, selection of evaluation items for interview and obstraction of proper evaluation factors. The major findings through this study are as follows; 1) The 12 major visual elements which possibly improve riverscape, based on abstraction of proper evaluation factors, are Dunchi, surface of the water,, equipment of river, buildings near riverside, river vertical and horizontal facilities like bridge, fine view, riverbed, water plant, naturalness, water's edge line, harmony and street trees by order. 2) Total numbers of adjective which describe 12 common factors are 25, such as clean, open, stable, quiet, comfortable, friendly, bright, natural etc. In addition, Dunchi was described 337 times by various adjectives, surface of the water was 200 times and arrangement of river was 146 times which is similar result with the order of 12 influential common factors. 3) Therefore, Dunchi, surface of the water and equipment of river are three most important factors which could create better riverscape. These three factors implies us how we supply good quality of urban river environment for the urban residents.

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.

CNS (Car Navigation System) is the most compatible candidate among various in-vehicle information systems as a provider of ITS (Intelligence Transport Systems) information. It generally consists of remote controller, display, CD-changer, GPS receiver and so on. Among them, display is the most important and critical element of the HMI (Human-Machine Interface) suggesting the digital map to the driver. Therefore, it is certain that the display gives cognitive, physical, mental and visual workloads to the driver which are directly related with the driver's and road safety with the success of ITS. Until now, various human factors techniques have been developed and applied to estimate the driver's workload and to collect the driver's requirements of the CNS digital map, for example, mental workload assessment, visual activity analysis, cognitive analysis and so on. In addition to these kinds of techniques, this research performed the human sensibility ergonomics approach to directly investigate and evaluate the driver's requirements and sensibilities of the real products.

The perception of landscape structure can he formed mode clearly, with including an auditory stimulus to a visual aspect. The waterfall, as an landscape element, will be considered of not only it's function and structure in landscape architecture designing but also harmony with environment which it has been situated, and contribution to the public goad. The purpose of this study was to establish more 7rational and practical design theory for the construction of waterfall. The number of subjects investigated were 47 of waterfall located in Mt. Palgong. In this study, the acoustic character of the waterfalls were investigated as an excellent effect to mask easily sensible noises. The correlations between the structure of waterfalls and water 1a17ing sound, which were useful for waterfall design and construction, were examined. It was discovered that the position of double distance of waterfall height From the waterfall is significant in the visual and acoustic perception of waterfall.

In this study the relative effects among trees, cars, wires and building facades on visual preference are measured with the photo-montage scenes, which were synthesized by computer graphic programs. In addition to these experiments, the interaction of each elements of streetscapes have been investigated. The results of this study can be summarized as follows ; (1) It was found that trees had a remarkable positive effect on preference for streetscapes, wires had a moderate negative effect, cars had a trivial effect and the effects of building facades were medium. (2) It was investigated that the building of residential type was most preferred among commercial, residential, and office building types. The next preferred building facade was the commercial type. (3) The interaction of each element of streetscapes also have effects on preference. Especially, it was found that the combined effects of building-wire and building-cars were more notable than other combined effects of two elements.

A deck crane is installed on the deck of a ship when there is no adequate facility for loading and unloading in dock or harbor. Deck cranes in Korea have been imported from abroad, and the import-substitution effect will arise if its production can be localized. Now, it is required to suggest the structural design of a deck crane that meet the domestic criterion, considering loading condition. In this study, the structural analysis of a pedestal in the deck crane was peformed by finite element method to investigate the strength requirement. In addition, the structural design of a pedestal was suggested by using ANSYS and VisualDOC. The optimized structure of a pedestal was determined, considering lightweight design.
