The purpose of this study was to examine statistical methods for assessing variance in students' learning attitudes over 2 months. The students' learning attitudes, measured by tutorial assessment sheets, were analyzed quantitatively by multidimensional scaling and cluster analysis. Items on the tutorial assessment sheets were divided throughout the practice period into two axes of speculation (behavior and partnership). At the initial and medium-term stages of this practice, the dispersion of student's consciousness for given assessments was able to determine the quantity. We could then determine the quantity of recognizing the importance of topics to learn, and consciousness for learning was a feature often found at the end of this practice.

The aim of this study was to investigate quantitatively the power ability of middle and older aged men in the vertical jump.
And, we would try to point out the changes with increasing ages and the influences of the environments factor to the power ability.
Based on the environment point of view, we put an emphasis and consideration on those who did physical exercises and also those who drove a car in a daily life.
Subjects were the health 201 men who visited the sports sauna training center of national stadium for physical exercises.
The power was calcurated from the force and velocity concerning of jumper's C.G. during the take off motion. The force was measured by using a strain gage type tranceducer, and the velocity was calcurated by integrating the equation of motion about of C.G.
Result:
The power ability of middle and older aged men in the vertical jump decreased with increasing ages.
The rate of decrease with every 5 years of age was 0.248 horse power, 2.960×10^-3 horse power in the maximum power and maximum power per body weight.
In comparison with the power ability of 25 years old, the power ability, in terms of maximum power per body weight, of 35 years old, 45 years old, 55 years old were 90.8%, 81.1%, 59.0%, respectively.
There were evidently differences between trained men and untrained men, and then car driver and no car driver in the power ability. The differences of maximum power per body weight were 12.190 × 10^-3 horse power, 9.231×10^-3 horse power, respectively.

Recently, the popular usage of the sauna bath has been greatly increased but this is not necessaeily based upon scientific ground.
This investigation has been made on the most ideal usage time with special emphasis on duration of time in the actual sauna room.
The usage pattern, in view of the times of taking the sauna room and the cold water, has been established.
And then the influences on the body function were measured.
The usage pattern were as follows (Repetition were all 3 times)
(1) 5 minutes stay in the sauna and 1 minute in the water
(2) 7 minutes stay in the sauna and 1 minute in the water
(3) 7 minutes stay in the sauna and 2 minutes in the water
(4) 10 minutes stay in the sauna and 2, 5 minutes in the watar
The result were as follows
1. The usage pattern (1) gave the good result for the function of whole body reaction time, patellar-tendon reflex time, maximum power of vertical jump.
Another usage pattern (2), (3), (4) gave the wrong result for those function.
2. There were no remarkable differences blood pressure, heart rate and skin temperature among the usage pattern (1), (2), (3), (4) .
3. Oxygen intake in the usage pattern (2) gave a large value than the usage pattern (1) .
In the view of the energy expenditure, it was recognized that the usage pattern (2) was the best usage.

We investigated whether the autonomic nervous system (ANS) modulation contribute to the bradycardia induced by endurance training. First, the meta-analysis approach was used to collect group mean values of maximal oxygen consumption (Vo₂max) and heart rate variability (HRV) from 14 studies involving 30 groups and 485 subjects. Subsequently, we performed a cross-sectional (n=116) and intervention (n=training group : 10 and control group : 6) studies. In both studies, ANS modulation was estimated by spectral analysis of HRV. In the meta-analysis and cross-sectional study, HR and natural logarithmic high frequency power (In HF power) were correlated with Vo₂max or peak oxygen uptake (peak Vo₂) . The significant negative correlations were found between HR and In HF power (meta-analysis and the cross-sectional study ; r² = 0.42 and 0.44, respectively) . Endurance training in the intervention study increased peak Vo₂ and resting In HF power, and decreased resting HR. These results strongly suggest that endurance training induces an increase in resting ANS modulation especially parasympathetic modulation. Furthermore, about half of the variability of resting HR can be accounted for by difference in parasympathetic modulation.

The purpose of this report is to clarify urologic problems in rural districts. The number of patients who visited our clinic for these 10 years were 7, 313 as new outpatient and 1802 as inpatient. Three main diseases of rural area were acute inflammation of lower urinary tract, benign prostatic hypertrophy and lithiasis of upper urinary tract. Infection of lower urinary tract and aggravation of malignant tumors might be influenced by rural works and bad circumstances. Monthly distribution of patients was also under the influence of rural works.

The aim of this studv was to clarify the effects of water immersion on the cardiovascular recovery process following submaximal steady state exercise on land. Seven male subjects (23 yrs old) underwent experiments under four separate conditions on separate days (15 minutes of cycling exercise at 50% and 80% maximal oxygen consumption followed by 16 minutes of recovery in a sitting position in water and out of water) . Concerning conditions in water, mean water temperature was 29.4 degrees, and the immersion level was set at xiphoid. Mean room temperature in out of water conditions, and during all conditions of exercise, was 24.4 degrees. Oxygen consumption (VO₂), heart rate (HR) and blood pressure (systolic: SBP, diastolic: DBP) were measured under each condi tion. Mean blood pressure was calculated from SBP and DBP (MBP=1/3× ( SBP-DBP) +DBP) . Stroke volume (SV) was measured by Doppler echocardiography, and then cardiac output (CO=SV×HR), total peripheral resistance (TPR=NIBP/CO) and arteriaVmixed venous oxygen difference (a-v O₂diff=VO₂/CO) were calculated. In comparison with the same exercise intensity condition, there were no significant differences between recovery processes of VO₂, HR, SBP, DBP and MBP in and out of water. SV and CO were significantly higher (p<0.05) during the recovery process in water than out of water (SV: at 50 and 80% maximal oxygen consumption conditions, CO: at 80% condition) . The TPR and a-v O₂diff were significantly lower (p<0.05) during the recovery process in water than out of water at 80% oxygen consumption condition. These results indicate that water immersion facilitates circulating blood volume during the recovery process without increasing blood pressure, especially during recovery after high intensity exercise. Therefore, we suggest that increased left ventricular preload with immersion would be an important factor in cardiovascular regulation not only at rest but also during recovery after exercise.

Objective: To identify the clinical and epidemiological characteristics of pernicious anemia (PA) in patients treated at Miyagami hospital on Tokunoshima Island.

Methods: We evaluated 14 patients with PA who were enrolled and treated from March 2009 to May 2014.

Results: The majority of patients were older than 50 years of age and primarily consisted of elderly women. Routine medical examinations revealed macrocytic anemia in 6 of the 14 patients (43%), although they were clinically asymptomatic and subsequently diagnosed with PA. The average number of patients per year was reported to be 3 (95% confidence interval [CI]: 1.25-3.42).

Conclusions: The annual incidence of PA per 100,000 individuals on Tokunoshima Island is possibly much higher than that previously reported in Japan. An increase in the elderly population, a negligence of the disease, and an ethnic and regional diversity may explain this discrepancy. As the annual incidence of PA may be higher than that previously reported, anemia must be carefully evaluated in the differential diagnosis of PA.
