  • In this paper we introduce the notion of quotient in-cline and obtain the structure of incline algebra. Moreover, we also introduce the notion of prime and maximal ideal in incline, and study some relations between them in incline algebra.

  • In this paper we show that if K is an incline with multiplicative identity and I is an r-ideal of k containing a unit u, then I = K. Moreover, we show that in a non-zero incline K with multiplicative identity and zero element, every proper r-ideal in K is contained in a maximal r-ideal of K.

  • Objective: The purpose of this study is to show the effectiveness of performing squat exercises at various angles to show the maximum muscle activity of the Vastus Medialis Oblique (VMO) and Biceps femoris (BF). Design: Cross-sectional study. Methods: A total of seventeen healthy young adults (8 males and 9 females) voluntarily participated in the study. All subjects randomly performed three different squat variations as follows: A squat performed with the ankle joint at $0^{\circ}$ of incline, a squat performed with the ankle joint at $5^{\circ}$ of incline, and a squat performed with the ankle joint at $10^{\circ}$ incline. Muscle activity was measured using surface electromyography. Electrodes were placed on the VMO and BF to measure the muscle activity on the various ankle angles for comparison analysis. Results: There was a significant increase in bilateral VMO muscle activation at $10^{\circ}$ of incline compared to $0^{\circ}$ and $5^{\circ}$ (p<0.05). Greater increases in muscle activation and exercise effect was observed with increasing incline angles of the board. Changes in bilateral BF muscle activity were found; however, none were found to be significant. Conclusions: Bilateral VMO activity was found to be significant when the squats were performed at an ankle angle of $10^{\circ}$ of incline when compared to at an ankle angle of $0^{\circ}$ and $5^{\circ}$ of incline. Squats performed on an incline can be recommended as an effective method to facilitate lower extremity muscle activities.

  • The purpose of this study was to identify the relationship of one repetition maximum between flat bench press exercise and incline bench press exercise, and so 40 male students of U-university were sampled purposedly, who were skilled in flat bench press and incline bench press exercises. After measuring lRM of each exercise by free barbell weight, the correlation analysis and the simple regression analysis were examined by using SPSS 120 at a significance level .05. The conclusions were as follows; Firstly, it was identified that 1RM of flat bench press exercise and incline bench press exercise were $89.2{\pm}25.9kg$, $67.1{\pm}22.1kg$ respectively, and the coefficient of correlation between two variables was 0.969, so the relationship was positive correlation. Secondly, it was identified that the regression equation predicted 1RM of incline bench press exercise was significant actually and statistically, so it was expressed that the equation was -6.648 + 0.827 (1RM of flat bench press exercise).

  • 본 연구는 8방향 경사와 회전운동이 만성요통환자의 통증과 동적균형에 미치는 영향을 알아보고자 시행되었다. 20명의 만성요통환자가 실험에 참여하였다. 10명(실험군)은 물리치료기구[온열팩{Hot Pack(H/P), 경피신경자극{Transcutaneous Electric Nerve Stimulation(TENS)}, 초음파{Ultra Sound(U/S)}]를 이용한 치료를 받은 후에 8방향 경사와 회전운동을 실시하였고 나머지 10명(대조군)은 물리치료기구를 이용한 치료만 실시되었다. 치료 중재는 주 3회, 6주 동안 적용되었다. 동적균형과 통증은 Star Excursion Balance Test(SEBT)과 Visual Analog Scale(VAS)를 이용하여 측정하였다. VAS 점수는 두 그룹 모두 감소하였으나 실험군에서 보다 유의하게 감소하였다. 동적균형 능력 또한 실험군에서 보다 유의한 증가를 나타내었다. 따라서 8방향 경사와 회전운동은 만성요통환자의 통증과 동적균형에 효과가 있었다고 사료된다.
