Operative treatment including a bone graft and an internal fixation was done in a fifteen-year old wrestler with transverse olecranon stress fracture. At 6 weeks after the operation, he could start active muscle strengthening exercise and returned to the previous level of exercise at 6 monthes after surgery. Conservative treatment including resting and muscle strengthening exercise was performed in an eighteen-year old baseball player with oblique olecranon stress fracture. At the follow-up of three months, he could start staged throwing exercise without pain or tenderness. He returned the previous level of throwing following strengthening exercise for 6 months.

Aerobic capacity is an important health indicator which is related to the probability of disease, disability, and mortality. Typically, endurance exercise is known as the primary method of improving aerobic capacity. Although most of resistance exercises are not considered for a good method increasing aerobic capacity, low to moderate intensity resistance exercise with short rest periods may improve aerobic capacity, especially old adults and most low to moderate risk patients suffering from CAD. This review is to understand that a number of physiological changes occur during both aerobic and resistance exercise, and to support that resistance exercise has advantages for improving aerobic capacity.

The study of subjects were 8 persons. The study measured VO2max of each person and substituted METs at exercise intensity of both VO2max 50% and VO2max 70% in accordance with energy consumption formula to set exercise time at energy consumption of both 300kcal and 600kcal. And, the study substituted inclination and rate at exercise intensity that was measured at preliminary test. T, B, NK cell varied depending upon aerobic exercise to have no significant difference of exercise intensity at relative ratio of T, B, NK lymphocyte of all of lymphocytes and to have significant difference of Expenditures Calorie (p<.01) and interaction (p<.05) by T cell and Expenditures Calorie (p<.01) by B cell and Expenditures Calorie (p <.001) and interaction (p<.05) by NK cell.

현재 국내에서 사용중인 낙석방지용 울타리는 낙석의 낙하운동에너지를 낙석방지망과 와이어 로프 및 지주에 의한 결합으로 흡수하는 역할을 하고 있으며 이중 와이어로프는 커다란 인장강도로 인하여 대형 낙석의 도로유입을 차단하는 중요한 역할을 하고 있다. 정력학적 관점에서는 와이어 로프는 인장강도가 큰 이유로 인하여 큰 하중을 지지할 수 있으나 그 변형량이 제한되는 이유로 인하여 낙석의 운동에너지를 흡수하는 측면에서 효율성이 저하되는 것이 일반적인 특성이다.(중략)

The purpose of this study was to investigate the effects of maximum and endurance resistance exercises on total work, blood viscosity, and erythrocyte volume ratio. The study subjects were selected as 15 men in their twenties with 12 months or more of resistance exercise experience, and the bench press 1RM was measured before the experiment, and the experiment for each condition was cross-allocated at intervals of one week, and the maximum repetition was performed in 6 sets. As a result, the total amount of exercise showed that the muscular endurance strength was higher than that of the maximum muscular strength (p<.001), and the blood viscosity and erythrocyte volume ratio were higher after exercise than before (p<.01) regardless of the total exercise amount. In summary, it was found that blood viscosity was not affected by exercise intensity and amount of exercise, and increased with one-time resistance exercise. This is clinically significant in constructing a resistance exercise program, and it is considered to be a reference material in creating an exercise program for clinical patients related to vascular disease.

As interest in wellness grows, There is a lot of research about monitoring individual health using wearable devices. Accordingly, a variety of methods have been studied to distinguish exercise from daily activities using wearable devices. Most of these existing studies are machine learning methods. However, there are problems with over-fitting on individual person's learning, data discontinuously recognition by independent segmenting and fake activity. This paper suggests a detection method for exercise activity based on the physiological response principle of heart rate up and down during exercise. This proposed method calculates activity intensity and heart rate from triaxial and photoplethysmography sensor to determine a heart rate recovery, then detects exercise by estimating activity intensity or detecting a heart rate rising state. Experimental results show that our proposed algorithm has 98.64% of averaged accuracy, 98.05% of averaged precision and 98.62% of averaged recall.

The purpose of the present investigation was to determine the effect of combine exercise on C-reactive protein(CRP) and adiponectin, and to asses whether combine exercise-induced changes in insulin resistance could be explained in part by changes in these in these inflammation markers. Twenty two participants (BMI >95 percentile for age and sex) were allocated exercise group(n=12) and control group(n=10). Subjects had their body shape, body composition, glucose. insulin, HOMA-IR, CPR and adiponectin levels measured. Modest improvements in body composition, insulin resistance markers were observed, however, adiponectin and CRP did not changes. These data suggest that adiponectin and CRP is not a contributory factor to the exercise-relateted improvements in insulin resistance. Additional studies are needed to assess the effects of different duration, modes and intensities of exercise on inflammation markers.

호우사상의 특성은 기후별, 국가별, 지역별, 계절별로 차이가 있는 것으로 알려져 있다. 강우운동 에너지는 호우사상 특성 중에 하나로서 강우강도와 강우운동에너지의 관계로 규명할 수 있다. 전세계 학자들이 자국의 호우사상을 분석하여 유도한 강우운동에너지식이 보고되고 있음에도 불구하고, 지난 40여 년 동안 전세계적으로 유독 미국의 호우사상으로부터 유도된 강우운동에너지식이 범용성을 가지고 사용되어 왔다. 본 연구는 강우운동에너지에 대한 연구로서 최근까지 학계에 보고된 강우운동에너지식을 수집하여 기후에 따른 해당 지역의 강우운동에너지 특성을 분석하였다. 본 연구는 강우운동에너지식이 유도된 방법과 호우사상에 초점을 맞추었으며, 이를 바탕으로 한국과 유사한 기후에서 유도된 강우운동에너지식과 한국의 강우운동에너지식을 비교 분석하였다.
