Objectives : This study aimed to investigate the effect of beat-keeping games in smartphone applications on improving executive functions in children with developmental delays. Methods : Three children diagnosed with developmental delay were included in this study. The ABA design used a single-subject experimental research design. The independent variable was the beat-keeping game. The game was held three times a week for a total of seven times for 20 minutes, including breaks. The dependent variable, "Visual-motor speed," was measured every session to assess if the beat-keeping game was effective in improving the participant's executive function. Further, before and after the intervention, "Children's Color Trails Test (CCTT)", "Block design," and "Finding hidden picture" were measured. Results : All three participants showed improvement in the performance of the beat-keeping game and the executive functions of "Visual-motor speed" and visual attention. Conclusions : Based on the results of this study, various effective applications for learning and intervention can be developed and applied to children with developmental delays who have difficulty in motivating themselves and lack attention.

Objectives : The authors investigated the practice of sleep hygiene and its effectiveness in general population who had experienced insomnia. If we find the items which be little practiced but especially effective, we would establish empirical an and theoretical basis to design the treatment program for insomnia, therefore apply it in clinical practice. Methods : The 226 subjects who had experienced insomnia, were at the age above 18 in Seoul, Korea. The questionnaire included the demographic data, the experience of insomnia, and the practices and effects of sleep hygiene instruction. The interview was administered face to face by the investigators. Results : The subjects reported that they practiced many of the sleep hygiene items related with arousal in sleep setting, and that those items were effective. The items such as 'get regular exercise each day(H)', 'take a hot bath(H)', 'concentrate on the pleasant feeling of relaxation(A)' were not usually practiced, but these items were reported very effective for sleep. Conclusion : The findings suggested that there were sleep hygiene items which should be educated and directed to practice actively in treatment program for insomniacs. Some items, which were especially reported low practice but highly effective, would be recommended to be studied about each therapeutic effectiveness in follow-up studies.

Introduction : The purpose of scholarly paper is to review of motor learning concepts and to examine in integration of motor learning research finding in occupational therapy services for adults with hemiplegia. Body : The principles of motor learning is stage of learning, type of task, practice and feedback. Depending on stage of learning, therapist need to apply of the principles. In early stage of learning, therapists should be promote patient's awareness about therapeutic goals, task performance environment and how to perform. Whole practice, blocked practice and constant practice improve performance skill. In the latter stage of learning, therapists have to design a intervention protocol for patient to use the implicit feedback. Random practice and open task facilitates performance skills. Conclusion : When establishing the a intervention plan for adults with hemiplegia, therapists should systematically developed the principles of motor learning. Intervention program must be established by applying the principles of motor learning in accordance with the learner's level of task performance, and modified depending on the therapeutic progress.

Anumber of prior studies have reported eye movement dysfunction in patients with dementia. The eye movement test which is non-invasive can evaluate the local brain function quantitatively. Therefore, it can be a useful method for characterizing regional brain abnormalities of patients with dementia. The aim of this paper is to review the literatures on eye movement abnormalities in dementia patients. Saccade system dysfunctions in Alzheimer disease include increased latency, reduced accuracy, and increased antisaccade error rates. Patients with frontotemporal dementia showed impaired reflexive saccade inhibition and increased latency and errors of antisaccade task. And delayed initiation of voluntary saccades, slow saccades, and increased errors and latency on antisaccade task were found in Huntington's disease. Patients with Parkinson’s disease dementia and dementia with Lewy bodies have characteristics of impaired in both reflexive saccade execution and complex saccade performance. However, there were few reports of abnormal eye movements in Creutzfeldt-Jakob disease; they could be found at the later stages after symptoms of dementia came to be evident, and secondary to cerebellar and vestibular involvement. Slowing of saccades and hypometric saccades might precede the supranuclear limitation of vertical gaze in PSP. Dysfunction of voluntary eyelid movements was a characteristic finding of PSP as well. In conclusion, patients with dementia can show various abnormal eye movements and they are related with cortial and subcortical brain dysfunctions. The research on localization of brain relevant to each symptom can promise more clinical implications of eye movement of dementia.

기존 자가발전 운동기구용 컨버터의 경우, 운동레벨을 조절하기 위한 입력임피던스 조절기능이 없거나, 조절기능을 추가하는 경우 복잡한 topology를 동반되는 경우가 일반적이다. 또한 복잡한 회로를 추가하게 되면 회로의 전체적인 부피가 증가하고, 원가가 상승할 뿐만 아니라, 회로의 신뢰성도 현저하게 저하시키는 등 회로 상용화를 어렵게 만든다. 본 논문에서는 입력 전압 및 전류 제어 방식을 이용하지 않고, 컨버터 구조 자체로 입력 임피던스를 제어하는 방식을 제안한다. 제안 방식은 입력전압, 입력전류 두 가지의 제어를 실행하지 않음으로써 복잡한 피드백 제어 단의 삭제가 가능하며, 이를 통해 회로의 높은 신뢰성 및 부피, 원가 감소 효과를 얻을 수 있다. 본 논문에서는 Flyback 컨버터를 이용하여, 이론적 특성 분석과 200W급 시작품을 통한 실험적 분석을 통해 그 타당성을 검증한다.

The maneuverability of a tugboat is affected by the slewing motion of a barge while the tug is navigating with the barge in water. Therefore, it is necessary to reduce the slewing motion of the barge to allow for safe towing work. In this study, a water tank experiment was performed to examine the factors affecting the slewing motion of a barge and improve course stability. The characteristics of slewing motion vary according to bow shape. Three barge models, each with a different bow shape, were selected as experimental subjects. A comprehensive analysis was performed to study the effects of various factors on the slewing motion of a barge such as the presence of a skeg and bridle, towing speed, and the length of the towline. The effect of the location of the skeg varied according to bow-hull form. The slewing motion of the barge decreased as the length of the towline increased, and this decrease was even greater when a bridle was connected to the towline. In addition, the slewing motion decreased significantly as the length of the bridle increased. The slewing angles did not show significant change with respect to towing speed.
