The development of mobile wireless technologies hasgenerated a considerable amount of excitement amongpractitioners and academics because it results in shifting theacademic environment from traditional settings to mobilelearning (m-learning) settings. Increasing numbers ofinstitutions of higher education offer courses using mobilewireless technologies as alternative teaching and learningtools. However, regardless of such interests in mobilewireless technologies in higher education, there is lack

For the upcoming ubiquitous computing environments in the u-health areas involve the measurement of physiological signals in the daily life. However, the measurement of those signals, such as the photoplethysmorgraphy (PPG), and the electrocardiogram (ECG), requires being still tight during the measurement in order to get the accurate result preventing noises caused by the casual movement. In this paper, we propose a method to obtain the accurate physiological signals in the situation where the

Purpose: In medical school, where high-scoring students are respected, a student who fails is regarded as a feckless individual who cannot survive in a competitive atmosphere. This study aims to analyze the experiences of failure inmedical school students using a qualitative approach. Methods: In-depth, semi-structured interviews were conducted with nine medical students who had failed the program and became a repeater or failed to pass the Korean Medical Licensure Exam, and three former and p

Purpose: The purpose of this paper was to assess if there is a relationship between Kolb learning styles and learner variables including age, gender, and grade retention among medical students.

The wearable healthcare system should be not only small and easy for users to wear them but accurate in measuring physiological signals in daily life without any inconvenience. To meet these requirements, we propose the U-healthcare System which consists of a Smart Headband and a Health-state Monitor program. It can monitor the health-state in walking and running. The Smart Headband measures a photo-plethysmography (PPG) signal at the forehead for monitoring the heart rate and acceleration signa

PURPOSE: This study investigated the present conditions of clinical clerkship management in Korea to make recommendations for it. METHODS: The data were collected between April 15 and May 30 in 2009 using questionnaires that were sent to the clerkship directors of 41 colleges of medicine and medical graduate schools. RESULTS: The elective course system was established in 78% of the institutions; the 6 core specialties were found in all medical schools. The duration of clerkship was longest in in

The spectral analysis of heart valve sound is a noninvasive diagnostic method known to be useful in evaluating the state of the heart valve function. This may provide early detection of valve calcification, thrombus or destruction, since previous studies have shown that the dominant frequency peak moved to a high frequency area when natural heart valve leaflets were calcified, stiffened or destroyed. However, it is important for a heart valve sound diagnostic system to find a proper spectral ana
