Purpose : This study was conducted to determine the effect of intervention using a smartphone application on abdominal muscle thickness and maximum voluntary ventilation when conducting pelvic floor muscle exercise (PFME). Methods : This study was performed on 14 subjects. They were divided into two groups; PFME using smartphone application (n=7), common PFME (n=7). Both of group executed the exercise 5 times a week for 1 weeks. Abdominal muscle thickness was measured using ultrasound. Maximum voluntary ventilation was measured using a spirometer. The smartphone application used the paid version of Kegel trainer. This material was analyzed by the paired t-test to compare differences on each group and the independent t-test to compare between the two groups. Results : The PFME group using the smartphone application showed a significant increase in the transverse abdominis and internal oblique muscles (p<.05). The common PFME group showed a significant increase in the internal oblique muscle (p<.05). There was no significant difference in variation of the muscle thickness between the two groups (p>.05). The PFME group using the smartphone application showed a significant increase in the maximal voluntary ventilation (p<.05). There was no significant difference in variation of the maximal voluntary ventilation between the two groups (p>.05). Conclusion : As a results of this study, PFME using a smartphone application seems to induce voluntary participation of subjects and maintain continuity against time constraints. As a result, it is thought that using a smartphone application when performing PFME is efficient and convenient in terms of research method. However, this study is difficult to generalize due to the small number of subjects and short intervention period. Therefore, additional research should be conducted by modifying and supplementing these limitations.

Purpose: The study examined the effect of dynamic taping and Kinesio Taping intervention on round shoulder posture, pectoralis minor length, craniovertebral angle, and balance in 20s adults with rounded shoulder posture. Methods: A total of 20s Adults with rounded shoulder posture were recruited and randomized to Group I (n = 15) and Group II (n = 15). Group I performed dynamic taping. Group II performed Kinesio Taping. Round shoulder posture and pectoralis minor length were measured using a tape measure. The craniovertebral angle was measured using a goniometer. Balance was measured using Biorescue. Results: As a result of comparison within groups, groups I and II showed a significant difference for round shoulder posture, pectoralis minor length, craniovertebral angle, and balance after the experiment (p < 0.05). In a comparison between the two groups, the experimental group showed a more significant difference in round shoulder posture, pectoralis minor length, craniovertebral angle, and balance than the control group (p < 0.05). Conclusion: This study showed that dynamic taping intervention was effective in round shoulder posture, pectoralis minor length, craniovertebral angle, and balance in 20s adults with rounded shoulder posture.

Purpose: This study aims to confirm the effects of stretching and meditation intervention on mental health-related anxiety, depression, and quality of life in college students in their 20s with sequelae of COVID-19. Methods: 30 men and women were randomly assigned to the stretching and meditation intervention group (10 people), the stretching intervention group (10 people), and the meditation group (10 people), and the experiment was conducted for 4 weeks. As for the analysis method, a paired t-test was performed for intra-group changes after 4 weeks, and one-way analysis of variance was performed for between-group changes. In addition, the significance level was set at 0.05. Results: Within-group changes in anxiety and depression were significantly different in all groups after 4 weeks (p < 0.05). There was a significant difference between SMG and SG and between SMG and MG in the change between groups after 4 weeks (p < 0.05). In the change in quality of life, there was a significant difference in all groups after 4 weeks (p < 0.05). There was also a significant difference between SMG and MG in the change between groups after 4 weeks. Conclusion: Based on the results of this study, the combined method of meditation and stretching intervention had a positive effect on the mental health of adults in their 20s and suggests the possibility of using it to improve mental health after recovering from COVID-19.

The study was to find out the effects of computer game and stretching on muscle tone and concentration. The subjects were 30 adults, who were divided into 15 stretching group and 15 control group after applying computer game for 120 minutes. The subjects measured muscle tone and concentration before experiment, the same measurements were made before and after applying the stretching. The muscle tone was respectively measured after 60 minutes and 120 minutes of computer game. The results showed that muscle tone increased significantly after 60 minutes and 120 minutes of computer game, and significantly decreased in the stretching intervention group. Concentration increased significantly after computer game, but there was no significant difference after application of stretching. In this study, computer game increased muscle tone and concentration, and stretching decreased increased muscle tone. Therefore, proper stretching after computer games will reduce musculoskeletal diseases caused by increased muscle tone, and development of appropriate game contents will be an effective tool for concentration training.

Purpose: The study aims to examine the effects of the proprioceptive neuromuscular facilitation pattern exercise and scrambler therapy on pain, range of motion (ROM), and shoulder dysfunction in breast cancer patients. Methods: In total, 30 breast cancer patients were recruited and randomized to group I (n = 10), group II (n = 10), and group III (n = 10). Pain was measured using a visual analogue scale, ROM was measured using a goniometer, and shoulder dysfunction was measured using a shoulder pain and disability index. Group I practiced the proprioceptive neuromuscular facilitation pattern exercise and underwent scrambler therapy, group II underwent scrambler therapy only, and group III practiced the proprioceptive neuromuscular facilitation pattern exercise only. Results: A within-groups comparison showed that all groups demonstrated significant differences in pain, ROM, and shoulder dysfunction after the experiment (p<0.05). Further, according to a comparison of the three groups, group I showed a more significant difference in effectiveness than groups II and III in terms of pain, ROM, and shoulder dysfunction before and after the experiment (p<0.05). Conclusion: This study showed that the proprioceptive neuromuscular facilitation pattern exercise and scrambler therapy are effective in treating pain, ROM issues, and shoulder dysfunction in breast cancer patients.

In this paper we fabricated QMSAs for 850MHz band on the teflon substrate with $\varepsilon_1-2.6, $ $t=1.6mm(\pm0.08)(CGP-500).$ We measured the resonant frequency and the return loss with cutting the gap region between radiation patch and ground plate by a 5mm length step by step. As a result we found that the measured data was not so bad unlike other papers when the gap region was closer to zero, especially under 10mm.

Forage sorghum (Sorghum bicolor x S. bicolor) was cultivated for knowing the effect of alum sludge application on its root growth in a mountainous site, Kumsan. And the results obtained are as follows: The available P205 content in the soil seemed to decrease with the advance of level of alum sludge application. And plant P content decreased with the advance of sludge application without phosphate fertilizer. With phosphate fertilizer, root number of the forage was greater than that without the fertilizer. The root growth of forage sorghum was the highest with NPK and the least in control and alum application, and it is not recommended to apply NPK and alum together for the growth of the forage root. (Key words : Root, Sorghum, Mineral, Sludge, Kumsan)
