Objective: This study is conducted on the differences between flat and curved displays with respect to location of focused points, posture and satisfaction as well as preferred tilt angles. Background: In order to avoid physical and eye fatigue caused by misplayed sitting posture, many studies have asserted that the display requires appropriate location, size and tilt angle as well as curvature. However, most studies have focused on the work environment and the results are varied in the extent. Method: Eye height data in sitting posture were collected from 30 participants. Participants selected the most comfortable viewing angle within the range from $0^{\circ}$ to $12^{\circ}$ while watching videos for both curved and flat display. Then, physical and eye fatigue and overall satisfaction were subjectively evaluated. Lateral diagram describing viewing display condition was set and used to develop linear models for expecting the preferred tilt angle. Results: Due to sitting in the natural viewing posture rather than upright, the eye height is lowered to about 4.6 centimeters, on average, for both displays showing no significant differences. In contrast, preferred angles for the two displays are significantly different and this can be interpreted that curvature vary the points focused. Two linear models as functions of sitting eye height are developed to expect preferred tilt angle for each display. Based on the result of overall satisfaction evaluation, curved display is statistically better than flat display. Conclusion: The results show that flat and curved displays are significantly different expect for the viewing posture. However, reasons for preferring curved display are not accurately factorized and the linear models are limited in the experiment condition such as size of display, distance between display and viewer and other physical environmental factors. Further studies on curved displays under more various conditions are required. Application: This study can contribute to use of the curved display in various way.

최근 사용자의 위치를 파악할 수 있는 기기가 보편화 되어감에 따라 사용자의 이동 경로를 이용한 다양한 서비스가 제공되고 있다. 이러한 서비스들은 사용자의 위치정보를 수집하여 각각의 요구사항에 맞게 가공하여 사용하고 있다. 그러나 이동경로를 나타내기 위해 수집되는 GPS등의 위치정보는 일반적으로 매우 방대하며, 이로 인해 경로 간 유사도 비교 시에 큰 연산 비용이 발생하게 된다. 이러한 문제를 해결하기 위해, 의미 있는 장소를 정의하고 장소간의 이동으로 모델링하여 이동 경로를 단순화하는 방법이 연구되고 있으나, 기존 연구들은 체류 시간과 거리만을 고려하여 이를 정의하고 있는 실정이다. 본 논문에서는 체류 시간과 거리, 상호작용 정보를 이용하여 특정 사용자의 의미 있는 장소 추출하는 방법을 제안한다. 또한 추출된 의미 있는 장소를 이용하여 경로를 단순화하여, 이동 경로 유사도 비교 시 드는 연산 비용을 줄일 수 있는 방법을 제안한다. 이를 위해, GPS를 통한 위치정보와 타인과의 상호작용 정보(통화, 문자 메시지 송수신등)를 이용하여 사용자와 친밀도가 높은 사람들을 정의하고 체류 시간과 거리, 주변에 있었던 사람의 정보를 기반으로 의미 있는 장소를 정의한다. 제안하는 방법을 검증하기 위해, 스마트폰 사용자로부터 실제 정보를 수집하였으며, 이를 이용하여 의미 있는 장소를 추출하고, 설문조사를 통해, 추출된 의미 있는 장소의 정확성을 확인하였다. 또한 의미 있는 장소로 단순화 한 이동경로를 이용하여 이동 경로 예측을 수행할 경우의 예측 정확도를 파악하기 위해 기존 방법과의 비교 실험을 진행하였으며, 연산에 소모되는 비용을 비교하여 제안하는 방법의 유용성을 검증하였다.

Objective: This study compared the muscle activities of the erector spinae (ES), the external oblique (EO), and the rectus abdominis (RA) on three different surfaces. The purpose of this study was to determine which surface induces the highest muscle activity during the plank exercises. The information from this study can be used to recommend plank exercises to athletes and patients with weak core muscles. Design: Cross-sectional study. Methods: The subjects include 20 adult males attending S University in Seoul. Participants completed each plank exercise on three different surfaces. To measure muscle activities, researchers used the values from electromyography. The measurement excluded the initial two and final two seconds and collected information on the RA, EO, and ES in each posture of each subject. Results: The left external oblique showed significant differences between the plank position on stable ground (ST) and the plank position using a suspension device (SL) (p<0.05) and between the plank position on the unstable ground (US) and SL (p<0.05). The right rectus abdominis and left rectus abdominis displayed statistically significant differences between the ST and the US (p<0.05) and between the ST and the SL (p<0.05). The right erector spinae had a statistically significant difference between ST and US (p<0.05). Conclusions: The plank exercise strengthens the core muscles effectively, and muscle activity is related to the posture of the exercise and the location of the muscle. These results suggest that plank exercises improve muscle activities. Additionally, plank exercises can be applied to general medical care.
