To investigate the effects of cardiac rehabilitation (CR) on cardiopulmonary exercise capacity in both elderly and younger patients with myocardial infarction (MI). Of the MI patients who received hospital-based CR between February 2012 and December 2015, we retrospectively reviewed the medical records of patients who continued a follow-up through the outpatient clinic. A total of 46 patients (18 elderly patients (${\geq}60years$) and 28 younger patient (< 60)) were included in this study. The subjects visited the clinic to perform aerobic exercises with ECG monitoring based on their initial exercise tolerance test outcome. The exercise capacity was measured by symptom-limited exercise tests before and after hospital-based CR. Before CR, the elderly group had a significantly lower exercise capacity in peak VO2, METs, anaerobic threshold, exercise time, respiratory exchange ratio (RER) than the younger group. After CR, elderly groups showed a significantly improved exercise capacity in exercise time, HRmax, HRrest, peak VO2, METs, anaerobic threshold, and RER. Both elderly and younger groups showed similar improvement of cardiopulmonary exercise capacity after hospital-based CR. There is a very low cardiac rehabilitation participation and referral rates with MI patients in Korea. It is considered necessary to further expand the participation of cardiac rehabilitation in elderly MI patients.

The purpose of this study was to examine the relationships among parental perception of home-based fine motor experiences in early childhood, home environment, and frequency of fine motor activities, and to investigate a mediating role of home environment in the process of parental perception influencing early childhood's frequency of fine motor activities. The data from 214 five-year-old children and their parents from six early childhood education centers in Gyeonggi province were collected and analyzed. The data were processed using IBM SPSS Statistics 23 and analyzed with descriptive statistics, independent samples t-tests, correlation analysis, multiple regression analysis, and bootstrapping analysis. The major findings were as follows: First, gender differences in parental perception, home environment, and frequency of fine motor activities existed in that values across all three variables were higher for girls than for boys. Second, parental perception, home environment and frequency of fine motor activities were positively correlated. Third, partial mediating effects of home environment on the relation between parental perception and the frequency of fine motor activities were found. These findings show an existence of gender differences in early childhood's fine motor activities. This research also affirms the significance of increasing the frequency of fine motor activities by enhancing parental perceptions for balanced motor development of boys and girls, and establishing a home environment conducive to fine motor activities at any time and in any location.

Objective : We tried to know the improvement and neurological effect of diabetes when the complex exercise training was applied on diabetes that delayed the recovery of the ischemic brain injury. Methods : We performed this study in a animal lab which located in Gyengsangbukdo. We used 10 diabetes rats with ischemic brain injury, which is induced by STZ. We applied the complex exercise training on the rats for 4 weeks. We executed the maze test to confirm the recovery of the brain function and checked the blood sugar to know the improvement. Results : As a result of applying the complex exercise on diabetes rats with ischemic brain injury, there was a significant reduce of error and escape time in 3 weeks and 1 weeks, respectively. There was no difference of the blood sugar in control but there was a significant improvement in experiment group after applying the exercise training in 4 weeks. Conclusion : The senile disease like stroke and diabetes was increased currently. It is important for rehabilitation to improve the quality of life during the remainder of their life. In the study, we've known the improvement of diabetes and the recovery of the brain function when the complex exercise training was applied the rats with both diabetes and the ischemic brain injury.

The purpose of this study was to evaluate the effect of exercise on cognitive function in the elderly through a systematic literature review and meta-analysis. For the study purpose, 14 studies were selected through a systematic process of using several databases and 11 studies were used to estimate the effect size of exercise on cognitive function. Meta-analysis was performed using a random effects model, and the effect size on cognitive function was calculated. The effect size for cognitive function of exercise intervention was Hedges' g=1.05 (95% CI: 0.61~1.50), indicating a large effect size. For heterogeneity, moderator analysis was performed using intervention, number of times per week, intervention duration, and cognitive function measurement. Cognitive function measurement was statistically significant, the other moderators did not significant difference. Results support that exercise has significant positive effects on cognitive function in elderly in korea. It also provided a basis that can be applied to exercise intervention design for cognitive function.

레저선박 중 하나인 8톤급 낚시선박에 대한 설계에 앞서, 우수한 복원성을 가지기 위해서는 실해역에 가장 적합한 선형의 개발이 중요하다. 특히 선행되어야 할 것은 선박의 운동 중 횡요 운동이 선박의 안전성 및 승선감에 미치는 영향에 대한 평가라 할 수 있다. 본 논문에서는 모형선 시험 중 전통적으로 사용되는 경사시험, 자유 횡요 시험 및 GZ 곡선을 통하여 기존선형과 대상선형에 대한 횡요 감쇠효과 및 복원성 평가를 수행하였다. 그리고 선형개선에 따른 GM계산 및 횡요운동 주기와 복원성 조사를 통해 낚시선박의 안전성과 승객의 승선감에 대한 영향을 조사하였다. 특히 자유횡요시험 시, 비접촉식 6자유도 운동계측기(Rodym DMM)와 무선 경사계를 이용한 계측 두 가지 방법을 함께 수행함으로서 횡요감쇠효과에 대한 신뢰도를 높였고 그 결과 기존 선형보다 대상 선형에 의한 감쇠효과가 더 크게 나타남을 확인할 수 있었다. 따라서 개선된 대상선형의 GZ곡선을 이용하여 설계시 적합한 복원성을 조사하였으며 자유횡요시험을 통하여 횡요주기가 증가함으로서 대상선형의 승선감이 더욱 향상된 것으로 분석되었다.

척추의 기본적인 생체 역학적 기능은 신체 부분간의 운동을 허용하고 척수와 신경근을 보호하는 것으로서 이러한 기능을 수행하기 위해서는 척추의 역학적 안정성이 필수적이다. 척추의 안정체계는 수동적 근 골격계, 능동적 근 골격계, 그리고 신경계의 세 가지 하부체계로 나누어지며 이들 하부체계는 각각 독립적으로 안정성에 관여하고 있다. 경추의 불안정성의 문제는 비정상적으로 증가된 추간관절의 운동에 의해 염증성의 신경을 압박 또는 신장하거나 또는 통증수용기가 많이 분포하는 인대, 관절낭, 섬유륜과 종판에 비정상적인 변형을 일으키는 것을 말한다. 안정성의 장애는 근육의 기능적 측면에서 국소적 안정체계와 포괄적 안정체계의 문제로 구분할 수 있다. 불안정한 경추 환자의 임상적 양상은 일반적으로 머리가 앞으로 나오고 전방 전위된 자세로 견갑대와 승모근 상부의 과활동성을 나타낸다. 또한 능동운동은 감소되지 않으나 수동운동에서 분절의 회전운동과 병진운동의 증가와 종말감의 변화가 있다. 경추의 불안정성을 관리하기 위한 실험적 연구로 전반적인 근육 훈련, 고유수용기 훈련, 그리고 도수치료의 세 가지 주된 접근법이 있고 실제적인 접근법으로는 고유수용성 재활프로그램, 칼텐본-에반스 접근법, 그리고, 슬링운동법 등이 있다. 각 방법들은 임상에서 나름대로의 이점이 있으며 환자의 상태에 따라 이들 방법을 단독으로 또는 병행해서 적용할 수 있을 것이다. 그러나 경추에서 이러한 방법들의 효과를 입증하는 증거는 부족하여 앞으로 이러한 방법에 대한 임상적 경험보다는 그 효과를 입증할 수 있는 연구가 필요하다고 본다.
