주의 집중력은 워킹메모리에 속하며 경두개직류전기자극은 워킹메모리를 향상시키는데 효과적이다. 본 연구는 경두개직류전기자극(Transcranial Direct Current Stimulation, tDCS)이 대학생들의 주의집중력에 미치는 영향에 대해 알아보기 위해 연구를 진행하였다. 본 연구는 대상자 37명의 대학생(23.08±3.33세)을 대상으로 tDCS그룹과 대조군으로 두 그룹으로 나누어 2018년 9월 3일부터 28일까지 연구를 진행하였다. tDCS그룹은(n1=19) 2mA로 13분씩 2회 26분간 적용하였으며, 대조군(n2=18)은 패드를 붙인 후 작동을 시키지 않았고 13분씩 2회 26분간 적용하였다. 연구는 주 3회 총 4주간 총 12회 진행되었다. 주의 집중력을 확인하기 위하여 뇌전도(Electroencephalogram) 검사를 하였으며, 연구결과 tDCS그룹이 주의집중력이 증가할수록 증가하는 SMR파(Sensory motor rhythm, p<0.01, 95% CI:-1.955, -0.459), 중간 베타파(p<0.05; 95% CI: 0.027, 0.943) 그리고 파워 비율(SMR+중간베타파/ 세타파, p<0.01, 95% CI: -1.764, -0.315)에서 유의한 향상을 보였다. 그러나 집중력 하락시 증가하는 세타파는 유의한 감소를 얻지 못했다(p>0.05). 결과값과 같이 tDCS적용시 주의집중력의 유의한 향상을 보였으며 본 연구를 기반으로 발전시켜 주의력 결핍환자들에게 적용에 대한 기초 자료로 사용될 수 있을 것이다. This study examined the change in the attention of University students after being given Transcranial Direct Current Stimulation (tDCS). The participants were divided randomly into two group (tDCS vs. Control). tDCS was applied to 37 university students (23.08±3.33 years). The tDCS group was applied 2 mA, for 13 minutes twice over a 26 minute period (n1 = 19). The control (n₂ = 18) was not applied after padding and was applied twice for 13 minutes over a 26 minute period. This study was conducted from September 3 to 28, 2018 and three times a week for a total of four weeks. The electroencephalogram was confirmed to affect attention. tDCS showed significant improvement in the results in the sensory motor rhythm wave (p<0.01, 95% CI: -1.955, -0.459), middle beta wave (p<0.05; 95% CI: 0.027, 0.943), and power ratio (p<0.01, 95% CI: -1.764, -0.315). The results showed that tDCS application increased the attention ability significantly. These results can be applied to attention deficit disorder (ADHD) patients and college students.

Purpose:The purpose of this study was to investigated the effect of stability on heel-heights of insole in healthy adults. Methods:Subjects of 39 males measured stability index of the Biodex Stability System(BSS) by wearing shoes of 2cm, 5cm insoles including bare feet. The BSS was consisted of a movable balance platform and the platform was interfaced with computer software that enables the device to serve as an assessment of balance performance. Stability index of the BSS included overall stability index(OSI), anteroposterior stability index (APSI), mediolateral stability index(MLSI). In the BSS, subjects were asked to step on to the platform of the BSS and assume a comfortable position while maintaining slight flexion in the knees, looking straight ahead. Subjects were trained for 10min for adaptation to the heel-height of insole and then they maintained double limb stance for 2min. Biodex platform set to convert Lv.8 into Lv.1 gradually. Results:There were statistically significant differences between heel-heights of insole and stability index of OSI, APSI, and MLSI(p<.05). The result of post-hoc test were as follows; 1)OSI had significant differences between bare feet and 2cm, 5cm. 2)APSI had significant differences between bare feet and 2cm, 5cm. 3)MLSI had significant differences between bare feet and 2cm, 5cm(p<.05). Conclusions:We found that the more heels of insole high, the more stability index increases. In particular, balance index of insole above 5cm more increased and we could acknowledge that the insole above 5cm more effected balance of healthy adults.

The use of therapeutic ultrasound(US) in humans with malignant neoplasms has been contra-indicated in physical therapy practice. Some studies have shown the results after application of US inhibited of tumor growth but some studies have shown the results facilitated of tumor growth in mouse. The purpose of this study were to determine the effects of US on rectal sarcoma(CT-26) in mouse and to determine the histological change of tumor. Thirty-five female BALB/C mouse, age 6 to 8 weeks received subcutaneous injection of 0.1 105 tumor cells. When tumors grew to 5 mm in diameters, the mouse were randomly assigned to control group(n=7) and high powered continuous US group(n=7) and low powered continuous US group(n=7) and high powered pulsed US group(n=7) and low powered pulsed US group(n=7). The experimental group (four groups) received 10 treatments over a 10-day period of 3 MHz ultrasound. Tumor dimension were measured on days 1(start of treatment), 5(midtreatment), and 10(end of treatment, preexcision and postexcision). Tumors were weighed after excision and the mouse were observated histological change of tumor. All tumors grew larger over time. Mean tumor weights(in grams) and volumes(in cubic millimeters) were 2.063 g and $2729.313\;mm^3$ for the high powered continuous US group 1.881 g and $2428.002\;mm^3$ for the low powered continuous US group 1.730 g and $2381.002\;mm^3$ for the high powered pulsed US 1.673 g and $2289.562\;mm^3$ for the low powered pulsed US group 1.670 g and $2297.333\;mm^3$ for the control group. Ultrasound increased the weight and volume of subcutaneous tumor in mouse. We urge caution in the use of ultrasound in the areas of tumors.
