목적 : 경추통에 대한 침구치료의 효과여부가 현재까지 시행된 무작위 대조군 시험의 검토에서 논란이 되고 있는데, 경추통에 대한 치료 효과의 검증에 최근 들어 경추 전만각도의 변화를 측정하는 것이 점차 많이 사용되고 있는 실정이다. 하지만 아직까지 변형된 형태의 경추 견인 등 몇몇 요소들이 경추전만을 변화시켰다는 보고는 있었으나, 침치료 중 深刺의 방법이 경추의 만곡을 변화시켰다는 보고는 없었다. 방법 : 자침의 방법 중 深刻(五刺法 중 合谷刺 또는 關刺)방법이 경추 전만의 변화를 주는가에 대하여 검증하기 위하여 심자 치료를 시행한 19명의 실험군과 치료를 시행하지 않고 단순히 방사선 촬영만 시행한 21명의 대조군의 단순 방사선 사진을 후향적 연구의 방법으로 비교하였으며, 아울러 심자 자침군에서는 VAS를 측정하여 통증의 정도의 변화를 함께 연구하였다. 결과 : 연구결과 자침을 시행하지 않은 대조군에서는 VAS와 경추 전만의 Cobb각도에서 유의성 있는 변화가 나타나지 않았으나, 심자의 방법으로 자침한 군에서는 치료 전후의 VAS가 유의한 차이를 나타내었고, 경추의 전만 각도에서도 경추 2번과 7번 사이의 Cobb의 각도에서 유의성 있는 변화를 나타내었다(p < 0.05). 결론 : 이러한 연구 결과들은 심자의 자침방법이 경주의 통증을 줄여줄 뿐만 아니라 경추의 구조적 변화를 일으킬 수 있음을 나타내 주는 것이다.

It is the first step to survive cardiac arrest for the general public to recognize cardiac arrest rapidly. The purpose of this study is to investigate the effective method of education by analyzing the degree of cardiac arrest recognition after performing the agonal breathing education in a video lecture or instructor-led lecture. The study subjects were assigned to either a video lecture or instructor-led lecture in a randomized way and were compared after the education according to the degree of recognition of cardiac arrest in the randomized controlled study. The study was conducted from October 30, 2015 to October 31, 2015. And the study subjects were 104 youths aged 15 years or older, of which 52 were selected as the experimental group and the remaining 52 as the control group. The results did not show a significant difference between these two groups when the subjects are given the video lecture where patients showed no reaction or sign of breathing(p=0.741). However, in the video lecture where there was no reaction of patients but still sign of agonal breathing, 43 people(82.7%) in the experimental group and 33 people(63.5%) in control group have successfully performed CPR and there has been a significant difference (p=0.006). Therefore, we could conclude that video lecture was more efficient than instructor-led lecture when teaching CPR.

The purpose of this study was to examine the effects of auricular acupressure on constipation and depression in shift-work nurses. The data was collected from May to June 2021 at A hospital in area I, and 40 nurses working in shifts participated in this study. This study was an open-label randomized controlled trial. 40 nurses who had constipation were randomized to the experimental group (n=20) or control group (n=20). Auricular acupressure was performed for 2 weeks at the corresponding points of constipation and depression for the experimental group. Auricular acupressure for 2 weeks significantly decreased constipation scores compared to the control group (F=7.74, p<.001). The mean difference in depression scores before and after acupressure in the experimental group (2.90±2.86) was larger than the difference in the control group (1.35±3.12), but it was not statistically significant (t=-1.64, p=.055). Auricular acupressure was effective in relieving constipation in shift-work nurses. Auricular acupressure could be considered as a treatment option for constipation.

We assessed the effects of intravenous (IV) ascorbic acid administration on fatigue in women undergoing laparoscopic myomectomy. We analyzed the secondary endpoint results of a randomized, double-blind, placebo-controlled trial. Fifty patients undergoing laparoscopic myomectomy received IV ascorbic acid (2g) or placebo (randomly 1:1 ratio) intravenously during surgery. On day 2 post-surgery, we measured the level of fatigue using the Brief Fatigue Inventory-Korean version. Forty-five women (experimental arm 23, control arm 22) were eligible for analysis after 5 women (experimental arm 2, control arm 3) were excluded due to withdrawal of consent, cancellation of surgery or non-measurement of the endpoints. The baseline and operative characteristics were similar between arms and the global fatigue score of the experimental arm (4.56 ± 2.63) was not significantly different from that of the control arm (5.21 ± 2.02, P = 0.351). However, the fatigue score of the experimental arm tended to be lower than that of the control arm in most domains. IV ascorbic acid administration did not significantly reduce the level of fatigue in women undergoing laparoscopic myomectomy as compared to placebo. More research is needed to better understand the effects of ascorbic acid on fatigue in surgical patients.

In this study we investigated the effects of physical therapeutic intervention through electromyography, ultrasonographic imaging and changes of the IL-$1{\beta}$, IGF-1 and IGF-2 in skeletal muscle of rats injured experimentally. The twenty Sprague-Dawley male rats were randomly divided into the 4 groups: a normal, a control, a low power laser and a neuromuscular electrical stimulation group. Abnormal spontaneous activities had not been shown, both in normal and skeletal muscle injured rats. The maximum diameter of the calf muscle was significantly increased in the low power laser and neuromuscular electrical stimulation groups compared with control group. The level of the serum IL-$1{\beta}$ was more decreased in the low power laser and neuromuscular electrical stimulation groups than that of control group. The activation level of the IGF-1 and the IGF-2 were significantly higher in the control, low power laser and neuromuscular electrical stimulation groups than that of normal group. However, there was no statistically significant difference among the control, low power laser and neuromuscular electrical stimulation groups.

This study is a randomized controlled trial to compare the effects of light therapy on stress, depression, sleep quality and quality of life in middle-aged women. The participants of this study were 56 middle-aged women who worked at the same office. Data collection period was from August 26 to September 13 for the control group and from September 16 to October 4 for the experimental group. Subjective stress, depression, quality of sleep and quality of life in middle-aged women were measured by Numeric Rating Scale (NRS), Center for Epidemiology studies of scale (CES-D), Verran & Synder-Halpern Sleep scale (VHS) and WHO Quality of Life Scale Abbreviated Version (WHOQOL-BREF). Stress index was measured using a Canopy9 RSA (IEMBIO, Gangwondo, Korea) equipment. The data were analyzed by mean, standard deviation, real number and percentage, χ²-test, t-test, repeated measures ANOVA and ANCOVA using IBM SPSS Statistics version 25.0. The results showed that the experimental group applying light therapy had significantly lower subjective stress (F=6.30, p<.001) and higher quality of life (F=2.80, p=.049) than the control group, There was no difference in objective stress index, depression, and sleep quality. As a result, light therapy is partially effective in subjective stress and quality of life for middle-aged women, and further research is needed on middle-aged women working in work environments with limited light exposure.

This study was performed to evaluate the restoration combined with resin infiltration (RI) of early cavitated smooth surface caries lesion in terms of microleakage. Flowable resin and resin-modified glass ionomer cement (RMGIC) were compared. Sound 20 extracted 3rd molars were divided into 2 groups randomly. Artificial decalcified lesion was induced. Cavities were prepared on the mesial and distal surfaces, and randomly set as experimental and control group. RI was applied to the experimental group before cavity restoration. The control group was restored without RI. In group I and II, flowable resin and RMGIC was used for restoration respectively. After thermocycling and silver nitrate immersion, microleakage was assessed by μ-CT. Depth of microleakage was lower in experimental group than control group only in group II (p = 0.05). Microleakage depth was lower in group II than group I in both experimental and control groups (p = 0.05). RI pretreatment before restoration of early cavitated caries lesions might reduce the microleakage and help long-term maintenance of restoration. In this study, RMGIC was less polymerization shrinkage. Restoration with RMGIC after RI pretreatment reduced the microleakage of the restoration compared to the flowable resin.
