  • The automated visual inspection system (machine vision system) for quality assurance is important factory automation equipment in the manufacturing industries, such as display, semiconductor, etc. There is a lot of demand for the machine vision engineers. However, there are no technical training courses for machine vision technologies in vocational schools, colleges and universities. In this paper, we present the implementation of line scan camera based equipment for technical training of the automated visual inspection system. The training system consists of the X-Y stage which is widely used in machine vision industries and its variable image resolution are set to $10-30{\mu}m$. Additionally, this training system can attach the industrial illumination, either the direct illuminator or coaxial illuminator, for verifying the effect of illuminations. This means that the trainee can have a practical training in various equipment conditions and the training system is similar to the automated visual inspection system in industries.

  • 현재 디지털 시네마의 압축 표준으로는 DCI(Digital Cinema Initiatives)에 의해 정지 영상 압축의 국제 표준인 JPEG-2000이 선정되어 있다. 하지만 영상 압축에 있어 또 하나의 국제 표준인 H.264/AVC는 현재까지 동영상 압축에 있어 과거 어떤 동영상 압축 코덱보다 큰 효율을 달성해왔다. 본 논문에서는 이 두 가지 압축 방법을 사용하여 디지털 시네마 압축에서 요구하는 시각적 무손실 압축을 연구하였다. 즉 실험 영상에 다양한 파라메터 값으로 JPEG-2000과 H.264/AVC 압축을 수행 하였고 산출된 결과를 시각적 무손실 압축의 환경 조건하에서 제시하였다. JPEG-2000의 경우 RATE 0.02, 0.03 이전의 PSNR 변화 값이 낮은 편이었으며, DCI 규격에도 만족시키는 결과를 보여주었다. H.264의 경우 압축 성능에 있어서 JPEG-2000보다 다소 우월한 결과를 보여주었다. 계층적 코딩을 통해 매체간 높은 호환성을 보장하는 H.264/AVC의 장점은 디지털 시네마의 배포에 적용 가능함을 함께 고려할 때 JPEG-2000과 함께 디지털 시네마를 위한 압축 표준으로 고려해 볼 만 하다.

  • The noise problem is one of the major problems associated with large cities and is considered important factor not only in maintenance but also in development of cities. Accordingly, the noise map is being increasingly used in city planning and design. However, the existing two-dimensional noise maps only show regional, planar distribution of noise. This study presented a method to build a data model for analyzing and visualizing noise levels at fine scale considering the vertical distribution of noise in a building. By expanding the 2D topology concept used in conventional GIS to 3D, it suggested a 3D GIS data model that makes 3D spatial queries, analyses and visualization possible and applied the proposed approach to building a 3D noise information system. By building and testing the system, the study showed different functionalities including 3D spatial queries and 3D visualization of noise levels varying temporally or according as the height of sound-proof walls. In each case, the population exposed to noise was quantitatively computed to illustrate the potential in the areas of city planning and design.

  • This study has been carried out to lay out a scheme to increase the recreational functions of the forests through improvement of trail environment. To achieve the objective, environmental characteristics of the trails, actual condition of the users, and status of the park management were investigated in the suburb parks of Tokyo, Japan in 1996. As the results, the managing agency of investigated parks has been set itself to activate the use rather than environment conservation and improvement of recreational environment in forests. However, for taking into account the behavior and the purpose of visits in forest, the enhancement of scenic quality and amenity in the parks is a pressing need in recreational conditions. Therefore, to increase the recreational functions in forests, selection of courses and keeping of natural trails in good condition, control of users to ensure amenity, introduction of planting methods to enhance scenic quality and educational effects, and management to efficient conservation of nature ecosystem are required.

  • The study was to improve the right to the enjoyment of culture of persons with visual impairment by increasing the accessibility to art exhibitions and exploring assistive measures through needs assessment survey of persons with visual impairment on arts exhibition. We used total 83 responses collected through an online survey. The result are as follows. First, watching movies at a teather was the most frequent leisure activity among persons with visual impairment, while respondents reported attending art exhibitions as the least frequent activity. Yet, 71.1% included attending art exhibitions as one of their top 5 culture and leisure activities. Most of the respondents reported the purpose of attending art exhibitions as fun. However, a primarily visual atmosphere prevented them from visiting the exhibition. Second, persons with visual impairment preferred approaching the art to have a closer look. More than about 50% of the respondents used their residual vision. Most of the respondents reported to use more than two senses when appreciating the exhibits. Moreover, respondents reported that devices/services for multi-sensory experiences would be helpful to appreciate the art. The findings imply that the consideration of the characteristics and needs of persons with visual impairment is required for establishing the environment of art exhibitions. This could further contribute to the improvement of the right to the enjoyment of leisure and culture of persons with visual impairment and lead to the realization of social integration.

  • This study compares the visual elements of the top five global beer brands currently in the Chinese market with those of the top five Chinese beer brands. The purpose of the research is to identify the importance of visual elements in the label design of beer package and to present the direction of efficient label design. To this end, it is a brand among visual elements of beer label design, and it investigates the label design of Chinese beer and global beer brand through the multi-accelerated comparative analysis method, focusing on color, illustration and layout, and analyzes the difference of elements appearing in the global beer label design from China by utilizing the recursive five-point scale. According to the research, the visual elements used in the Chinese beer brand were more complex compared to the global beer brand, and most layouts were similar, making the product less differentiated. On the other hand, the global beer brand has secured brand identity and differentiation based on its iconic visual elements and diversity of layout. In order to establish itself as a strong brand in consumers' minds, the Chinese beer brand needs differentiated label design through active use of unique brand design.

  • The purpose of this study is to look at the fun that high school students from blind schools feel in sports programs. A questionnaire was used to collect data from 10 out of 12 blind schools nationwide, including 122 male and 102 female students. Research tools are open questionnaires and questions are as follows. - Questionnaire: "Write down three of the most interesting things about sports programs." The data analysis was done with frequency analysis and the following conclusions were drawn. First, male high school students at blind schools are able to build up their physical strength in the area of competent factors (control-self) (23, 21.5%), in the area of competent factors (7, 77.8%) and in the area of motion-related factors (competition) (24, 15.1%), and in the area of non-execution factors (26, 37.7%), Second, high school girls with visual impairments did not respond in the areas of proficiency (control-self) because of stress release (25, 26.6%), in the areas of control-tain), in the areas of movement (competition) because they were able to do various exercises (22, 15.7%), and in the areas of non-watering (environmental) (18, 37.5%). Third, in the sports program comparative analysis of high school students between genders of blind schools, boys are interested in health and physical fitness in the field of competent factors (control-self) and girls are considered to be a means of relieving stress. In the field of competent factors (control-others), boys and girls can react to a variety of sports opportunities. In the future, by studying the fun of students in the physical education program through research to find out more fun in the school physical education program, we will explore practical ways to maximize student participation and increase motivation level The educational aspect of the process, that is, the educational value provided by the physical education, should be composed of content that can change the thinking and behavior of the teacher and the student so that the program contents and operation method.
