The purpose of this study was to evaluate the effect of regular aerobic exercise on blood lipid and HPA axis hormone in middle-aged women. The subject for this study were 14 healthy women who were 35-45years. They didn`t have any history cardiovascular disease. The subject were divided into two group: swimming (experimental) group (n=7) and control group (n=7). The swimming exercise protocol for experimental group consisted of a 10-minute warm-up, 40-minute main exercise, and 10-minute cool down. Exercise intensity was range from 55% to 80%HRmax. Exercise was performed 5-6 days/a week during 16 weeks. The result of this study as follows. 1. The change of blood lipid variable. 1) The TC of an experimental group was decreased significantly, whereas that of a control group was no significant different after exercise. 2) The TG of an experimental group was decreased significantly, whereas that of a control group was no significant different after exercise. 3) The HDL-C of an experimental group were increased significantly whereas that of a control group was no significant different after exercise. 4) The ACTH of an experimental group were increased significantly, whereas that of a control group was no significant different after exercise. 5) The cortisol of an experimental group were increased significantly, whereas that of a control group was no significant different after exercise. In conclusion, swimming exercise performed during 16 weeks in this study was affected positive change in blood lipid and HPA axis hormone. Therefore we think the swimming exercise seems to be a available method for improving cardiovascular disease and lipid utilization.

본 연구는 모바일 Android OS에서 텍스쳐 포맷인 ASTC의 메모리 점유율, CPU 처리 속도, 평균 프레임 비교 검증을 진행하였다. 실험 환경 구성으로 가상의 게임 씬을 구현하여 Android 플랫폼으로 빌드하였다. 이를 바탕으로 비교 검증 데이터를 추출하였다. ASTC는 ETC보다 2D 텍스쳐의 메모리 사용량에서 36% 낮은 점유율을 보였다. CPU 연산 처리에서는 18% 빠른 처리속도를 보였다. 평균 프레임은 58% 더 높은 54프레임을 확인하였다. 스마트 모바일 게임 환경에서 ASTC는 ETC보다 비교우위의 결과를 확인하였다. This study verified the memory occupancy, CPU processing speed, and average frame comparison of texture formats of ASTC and ETC in mobile Android OS. The virtual game scene was implemented as an experimental environment and built on the Android platform. Based on this, comparative verification data was extracted. ASTC has a 36% lower share of memory usage of 2D textures than ETC. CPU processing speed was 18% faster. The average frame confirmed 54 frames that was 58% higher. In the smart mobile game environment, ASTC confirmed the result of comparative advantage over ETC.

Although maximal exercise load tests are used in the athletic and medical fields, studies on wrestlers are few. To investigate the physiological characteristics of wrestlers, cardiorespiratory responses to symptom-limited maximal exercise loading were studied by Bruce protocol in 8 wrestlers and in 8 age-matched non-athletes, which served as controls. The inclination of the treadmill was fixed at 6% degree, & the initial velocity of the test was 80m/min. In the wrestlers, VO₂ max was significantly smaller, and O₂ pulse and AT were significantly larger than those in the controls, but HR max and AT/VO₂ max were essentially similar in both groups. The VO₂ max in the wrestlers was also smaller than that in the other game players. Ventilatory parameters such as RR, VE/M², VE/VO₂, VE/VCO₂, and VT/VC at maximal exercise showed no significant differences between two groups. However, VE/MVV was significantly higher in the wrestlers. These facts suggest that aerobic capacity and ventilatory reserve are diminished in the wrestlers.
