We propose a system that automatically recognizes the tense or relaxed condition of scrolling-shooting game subject that plays. Existing study compares the changed values of source of stimulation to the player by suggesting the source, and thus involves limitation in automatic classification. This study applies SOM of unsupervised learning for automatic classification and recognition of player's condition change. Application of SOM for automatic recognition of tense and relaxed condition is composed of two steps. First, ECG measurement and analysis, is to extract characteristic vector through HRV analysis by measuring ECG after having the player play the game. Secondly, SOM learning and recognition, is to classify and recognize the tense and relaxed conditions of player through SOM learning of the input vectors of heart beat signals that the characteristic extracted. Experiment results are divided into three groups. The first is HRV frequency change and the second the SOM learning results of heart beat signal. The third is the analysis of match rate to identify SOM learning performance. As a result of matching the LF/HF ratio of HRV frequency analysis to the distance of winner neuron of SOM based on 1.5, a match rate of 72% performance in average was shown.

Display technology has recently made enormous progress. In particular, display companies are competing each other to develop flexible display. Curved display, as a precursor of flexible display, are now used for smart phones and TVs. Curved monitors have been just introduced in the market, and are used for office work or entertainment. The aim of the current study was to investigate whether the curvature of a 42" multi-monitor affects postural control when it is used for entertainment purpose. The current study used two curvature levels (flat and 600mm). Ten college students [mean(SD) age = 20.9 (1.5)] with at least 20/25 visual acuity, and without color blindness and musculoskeletal disorders participated in this study. In a typical VDT environment, each participant played a car racing video game using a steering wheel and pedals for 30 minutes at each curvature level. During the video game, a pressure mat on the seat pan measured the participant's COP (Center of Pressure), and from which four measures (Mean Velocity, Median Power Frequency, Root-Mean-Square Distance, and 95% Confidence Ellipse Area) were derived. A larger AP (Anterior-Posterior) RMS distance was observed in the flat condition, indicating more forward-backward upper body movements. It can be partly due to more variability in visual distance across display, and hence longer ocular accommodation time in the case of the flat display. In addition, a different level of presence or attention between two curvature conditions can lead to such a difference. Any potential effect of such a behavioral change by display curvature on musculoskeletal disorders should be further investigated.

In this paper, we propose a synchronized playback method of 3D reference model and video by extracting golf swing information from learner's golf video to precisely compare and analyze each motion in each position and time in the golf swing, and present the implementation result. In order to synchronize the 3D model with the learner's swing video, the learner's golf swing movie is first photographed and relative time information is extracted from the photographed video according to the position of the golf club from the address posture to the finishing posture. Through applying time information from learners' swing video to a 3D reference model that rigs the motion information of a pro-golfer's captured swing motion at 120 frames per second through high-quality motion capture equipment into a 3D model and by synchronizing the 3D reference model with the learner's swing video, the learner can correct or learn his / her posture by precisely comparing his or her posture with the reference model at each position of the golf swing. Synchronized playback can be used to improve the functionality of manually adjusting system for comparing and analyzing the reference model and learner's golf swing. Except for the part where the image processing technology that detects each position of the golf posture is applied, It is expected that the method of automatically extracting the time information of each location from the video and of synchronized playback can be extended to general life sports field.

In sports videos, text provides valuable information about the game such as scores and information about the players. This paper proposed a robust recognition method of player name in golf videos. In golf, most of users want to search the scenes which contain the play shots of favorite players. We use text information in golf videos for robust extraction of player information, By using OCR, we have obtained the text information, and then recognized the player information from player name DB. We can search the scenes of favorite players by using this player information. By conducting experiments on several golf videos, we demonstrate that our method achieves impressive performance with respect to the robustness.

The purpose of this study is to examine a unique characteristic of the colors of the costumes in Korean basic culture in the aim of seeking the characteristics and the conceptual meanings of colors found in the majority’s culture. The scope of the basic culture was divided into folk belief, folk game and folk play. Within these limits, the colors of the dress, accessories, instruments were extracted by comparing with the naked eye in NCS Color System. For the analysis of hue and tone, the secondary dimensional analysis using NCS color system and the three-dimensional analysis using the software, COLOR 3D Version 2.0, were done. The result of this investigation is that the colors of the costume in the Korean basic culture are white, gray and black of achromatic color and yellow, yellowish red and purplish blue. This confirms that the colors based on Five-elements color are becoming the basis too basic culture. And Arche-pattern, which is a characteristic commonly found in the Korean traditional society, was shown as a characteristic of color. The colors of the costumes in Korean basic culture are uniquely adopted by the Korean civilians according to their religious and philosophical living standard. This study is meaningful in seeking a root for the formation of their unique color culture.

Purpose: The present study purposed to investigate the current state of harmful business places around schools and to survey and analyze how much middle school students know about school environment hygiene purification zones, which have not been much effective. Methods: In addition, this study clarified the problem of harmful environment around schools by inquiring into students' value and perception on worsening harmful environment around schools and provided basic materials necessary for making policies on school education and the protection of educational environment. For these purposes, we conducted a questionnaire survey of 1,000 middle school students in Gyeonggi-do on their perception on harmful environment around their schools, and drew conclusions as follows. Result: Students' knowledge about the School Health Act was low, and they generally thought that the law does not play its role substantially and efficiently in purifying and regulating harmful environment and regulations are superficial and temporary. To the question of whether harmful businesses observe laws for purifying environment around schools, most of the students replied negatively. In actuality, as most of harmful businesses running at school environment hygiene purification zones are stationeries with game rooms, comic book stores, PC rooms, etc., which are highly accessible to students, they become serious problems in school environment. Conclusion: As it is required to make continuous and systematic surveys and researches on the school environment hygiene purification zones, we need to manage school environment efficiently through cooperation among the government, education offices and individual schools.

An anterior dislocation of the elbow without a fracture of the olecranon is an extremely rare injury. This paper reports a 36-year-old male who stumbled and fell on his outstretched hand during a soccer game. The anteroposterior and lateral radiographs indicated a simple anterior dislocation of the elbow, which was reduced using a closed method. The elbow joint was stable in the range of motion, but the sensation of the two ulnar digits was still reduced. MRI was useful for the identification of the pathoanatomy. At the follow-up examination three months after the initial trauma, the hypesthesia has fully recovered and the patient regained the full range of the elbow and forearm motion without pain and instability. After 18 months, the patient had a normal elbow function, and could play various sports. If an anterior elbow dislocation is detected early, a closed reduction with careful pathoanatomical considerations would be successful.
