Recently, the demand for touch screen displays has increased, especially on small-sized equipment such as smart phone, digital camera, and wearable computers. This study has been conducted on experimental design for measuring the minimum touch button size that should be guaranteed for accessibility. It was intended to analyze existing experimental methods and to compare their design elements. This study suggests a reliable experimental method.

이 연구에서는 우리나라의 모바일 앱 접근성 KS, 미국의 재활법 508조 개정 표준 및 유럽의 BBC 지침을 기준으로 개방형 플랫폼인 안드로이드 모바일 뱅킹 앱의 접근성을 분석하였다. 실험 결과, 우리나라 8개 시중은행의 모바일 뱅킹 앱 중 상기 3가지 표준의 세부 항목을 모두 만족하는 앱은 한 곳도 없었다. 대표적인 위반항목은 대체 텍스트 미비, 키보드 초점 위반, 컨트롤 크기 및 간격 미준수, 명도대비 비율 낮음 등이었다. 이들 위반사례는 시각장애인, 상지장애인 및 저시력인과 고령자의 접근을 불가능하게 만든다는 점에서 치명적인 오류이다. 모바일 뱅킹 앱이 접근성을 준수하지 않는 원인에 있어서는 모바일 앱 개발자와 제공자들의 접근성에 관한 인식이 낮고 접근성 구현 방법을 제대로 숙지하지 못한 것으로 분석되었다. 우리나라의 모바일 앱 접근성 지침을 재활법 508조 개정 표준 및 BBC 표준과 비교한 결과, 많은 항목이 누락되어 있었다. 또한 평가 기준이 모호하고 추상적이어서 개발자들이 구체적으로 참고하기 어려운 측면이 있는 것으로 판단되었다. 따라서 모바일 앱 접근성 향상을 위한 개발자 및 정부의 노력과 더불어 표준의 보완이 필요하다. In this study, we analyzed the accessibility of open platform Android mobile banking applications, based on Korean mobile application accessibility KS standard, Section 508 technical standard of Rehabilitation Act, and European BBC guidelines. Experimental result showed that there are no mobile banking applications of 8 commercial banks in Korea that satisfy all guidelines of three standards. Typical violations included missing alternative text, keyboard focus violations, control size and spacing non-compliance, and low contrast ratio. These violations are fatal in that they make the accessibility of the blind, the disabled and the low vision and the elderly impossible. The reason that mobile banking applications do not comply with accessibility is that mobile application developers and providers have low awareness of accessibility and do not know how to implement accessibility properly. Comparing Korea mobile application accessibility guidelines with the revised standard of the Section 508 of Rehabilitation Act and the BBC standard, many guidelines are missing. Also, evaluation criteria are ambiguous and abstract, making it difficult for developers to refer specifically. Therefore, improving mobile application accessibility requires developer and government efforts and complementation of standards.

To establish a criterion for evaluation of physical fitness and to set up standard exercise load as would be compatible with the examination of cardiovascular functions in the Korean adult males, particularly in sportsmen, the present experiment was undertaken. A total of 480male college students were subject to step-up test for various duration using boxes of variable heights. The results may be summarized as follows: 1. The average lower leg length in college students of physical education was 89.55cm. 2. The amount o maximum 02 intake per min as was observed during stepping up and down on a box 45 cm heigh for a duration of 5 min was 3.47 liters which is equivalent to 89.5% of maximal 0₂ intake. 3. The maximum heart rate observed during step-up exercise of the same intensity as in 2 was 182min. which was about 96.3 of maximal heart rate attained by those subjects. 4. Stepping up and down on a 45cm box for 5 min. at a rate of 30 complete steps per min. was most suitable for evaluating physical fitness of sportsmen as judged by cardiovascular response. 5. Index of fitness was calculated by the equation time of stepping in seconds / 2x sum of 3 counts of the pulse X 100. The average fitness score as was caculated by the above equation was 79. 5 ±8.5 in college students of physical education.

Analyzing the personal histories of 51 top class former athletes, specially in the aspects of diseases and the causes of death, it was found that the average age of death was 42. 6 years and the highest frequency in the causes of death was 45% by cardiovascular diseases and the next cause was respiratory diseases with 31.3%.
