  • The purpose of this study is to interpret the visual and auditory images and cognitive characteristics about townscapes in Namwon city. It was acquired the survey results about 8 types of verbal interviews and 2 kinds of sketch maps which are based on urban images from 102 Namwon residents. They held in a variety of images of Namwon in their minds such as Jiri mountain, clean environment, sightseeing, special products, urban/building structures, Korean classical music, historical novel, local sports, and emotional images. The nice streets or places which the residents recommended are the places which have abundant natural areas, psychological peace and rest, available space for physical activity, places for performances and events, and regional attractions. The streets or places which they didn't like are decadent places, and areas of crowded traffic. The transition times of visual and auditory scene can be classified with the Saemaul movement in the 1970's(the rural new community movement) and the improvement of the city in the 1990's. The elements of visual images in Namwon city on the basis of the cognitive maps were expressed such elements as paths, districts, nodes, edges, and landmarks. The elements of auditory images, which are on the basis of the concept of the soundscape, included sounds of narrative musical form unique to Korea; p'ansori, sounds of traditional markets, and sounds of nature. It was found that the imageability of visual and auditory images is relatively clear in specific areas in Namwon city.

  • Objectives : Children with attention-deficit hyperactivity disorder (ADHD) have been shown to display more inhibitory deficits and executive function deficits. This study investigated the treatment effects of neurofeedback (NF) training on executive function by comparing the results of neuropsychological tests of the trained children at pre- and post-training. Methods : Fifteen children with ADHD, aged 6 to 14 years, participated in the study. The NF treatment consisted of slow cortical potential (SCP) training and these sessions took place once a week. The ADHD children performed 20 sessions of NF training within 6 months. Pre-training and post-training assessments encompassed Continuous Performance Test (CPT), Stroop Test, Children's Color Trails Test I&II (CCTT) and Wisconsin Card Sorting Test (WCST). Results : Patients receiving NF training showed significant improvement in visual commission error and standard deviation of auditory response time on CPT ; and total errors on WCST. But there was no significant improvement in the Stroop test and CCTT. Conclusion : SCP training using NF improves the self-regulatory capacities and impulsivity in ADHD patient, especially impulsivity in visual stimulation tasks. This study showed evidence of clinical efficacy of NF on executive function in ADHD.

  • With the development of deep learning, it is possible to solve various computer non-specialized problems such as image processing. However, most image processing methods use only the visual information of the image to process the image. Text data such as descriptions and annotations related to images may provide additional tactile and visual information that is difficult to obtain from the image itself. In this paper, we intend to improve image classification accuracy through a deep learning model that analyzes images and texts using image-text pairs. The proposed model showed an approximately 11% classification accuracy improvement over the deep learning model using only image information.
