본 논문에서, 생물계로 자기자극장치를 사용할 경우 잠재적인 사용에 대한 전력소자 응용제어 기술에 대해 언급 하고자 한다. 자기자극장치의 효과는 자기 자극코일에 의해 전달된 전류 펄스파형에 유도한 전계와 기하학 구성에 의존한다. TMS는 두뇌에 있는 전계를 유도하는 전자장의 펄스를 머리의 외부에서 자극하게 된다. TMS는 두뇌의 자극을 통해, 진단 및 치료에 있는 수많은 응용이 가능하다. 이러한 요소들은 코일의 구성과 전원 장치와 크기의 등가적 요구와 특성으로 매우 중요한 기능을 가지게 된다. 제안하고자 하는 해결방법은 입력에 대하여 가변크기와 주기를 가지는 전류펄스 발생을 가진다. 또한, 해결방법은 전원에서 부하로 에너지 전송과 축적의 요소를 기본으로 할 수가 있다. 제안한 방식으로, 전력 회로 매개 변수의 충분한 통제를 통한 기획과 전략으로 단극파형 또는 양극 파형을 얻을 수가 있었다.

Objectives: The purpose of this study was to identify the effects of music intervention on the patient's fear and anxiety during scaling. Methods: 360 patients who had visited W University dental hygiene laboratory were selected as study subjects and divided into experiment group and control group. Results: Study results showed that the control group (71.9%) and the experimental group (75.1%) had experiences avoiding dental treatment due to fear. In the control group (37.6%) and experimental group (40.6%), the highest influencing factor was the sound of machine and followed by pain. The experimental group preferred classical music, followed by pop songs, trot music and instrumental music. In the experimental group (83.3%), fear and anxiety were alleviated by music, and 77.9% of the patients mentioned they would recommend music for scaling to other patients. There was an interaction effect (p=0.014) between the groups before and after the measurement of the lowest blood pressure. There was a significant difference in pulse before and after pulse measurement (p=0.000). There was a significant difference in respiration between groups (p=0.042) and before and after respiration (p=0.030). Conclusions: Study results showed that music intervention that utilizes music during scaling showed significant effects on the alleviation of fear and anxiety, affecting Pulse number among vital signs. Therefore, more systematic program is to be required to alleviate dental fear and anxiety with music therapy not only for scaling, but also for dental clinic in the future.

Background: Eight-Constitution Medicine (ECM) classifies the human body into eight constitutions. Diagnosis of discrimination of the eight constitutions depends on a unique pulse diagnosis. However, pulse diagnosis is subjective and requires vigorous training. Objectives: This study aims to analyze the validity and reliability of the Eight-Constitution Questionnaire as a diagnostic method. Methods: Participants of this study were outpatients in six ECM clinics located in Seoul. The resources were collected from 409 patients who were classified into one of the eightconstitutions according to their pulse types and their responses to constitution-acupuncture therapy. SPSS 13.0 for Windows was used for statistical analysis: factor analysis, reliability analysis, independent sample t-test, and multinomial logistic regression were used to verify the results. Results and Conclusions: 1. The proportion of participants' constitutions is in the order of Pancreotonia (23.7%), Colonotonia (19.8%), Pulmotonia (18.1%), Hepatonia (16.9%), Vesicotonia (8.1%), Cholecystotonia (7.3%), Renotonia (5.3%) and Gastrotonia (0.7%). 2. Sevencomponents and 74 items were selected through factor factor and relaibility analysis performed on about 251 items. 3. The firstcomponent's mean is significantly higher in Pancreotonia than that in other constitutions (p<0.05). The second is in Pulmotonia and Colonotonia, whereas the third is in Hepatonia and Cholecystotonia. Fifth is in Vesicotonia, the sixth is in Colonotonia, and the fourth and seventh are not significant in specific constitutions. 4. The percentage that Pancreotonia is correctly predicted is 96.9%, Pulmotonia is 91.9%, Colonotonia is 91.4%, Hepatonia is 88.4%, Vesicotonia is 81.8%, Gastrotonia is 66.7%, Renotonia is 66.7%, Choleeystotonia is 30.0%, and the total percentage is 85.3%.

Background: This study evaluated the efficacy of virtual reality (VR) distraction and counter-stimulation (CS) on dental anxiety and pain perception to local anesthesia in children. Methods: A prospective, randomized, single-blinded interventional clinical trial with a parallel design was used. Seventy children 7-11 years old who required local anesthesia (LA) for pulp therapy or tooth extraction were recruited and allocated to two groups with equal distribution based on the intervention. Group CS (n = 35) received CS and Group VR (n = 35) received VR distraction with ANTVR glasses. Anxiety levels (using pulse rate) were evaluated before, during, and after administration of local anesthesia, while pain perception was assessed immediately after the injection. Wong-Baker faces pain-rating scale (WBFPS), visual analog scale (VAS), and Venham's clinical anxiety rating scale (VCARS) were used for pain evaluation. Student's t-test was used to test the mean difference between groups, and repeated measures ANOVA was used to test the mean difference of pulse rates. Results: Significant differences in mean pulse rates were observed in both groups, while children in the VR group had a higher reduction (P < 0.05), and the mean VCARS scores were significant in the VR group (P < 0.05). Mean WBFPS scores showed less pain perception to LA needle prick in the CS group while the same change was observed in the VR group with VAS scores. Conclusions: VR distraction is better than CS for reducing anxiety to injection in children undergoing extraction and pulpectomy.

Purpose: The purpose of this study was to investigate the effect of the intensity of microcurrent stimulation (with currents of 50 ${\mu}A$, 100 ${\mu}A$ and 300 ${\mu}A$ using a pulse frequency of 5 pps) on wound healing in rats. Methods: Sixty male Korean rats were randomly divided into four groups of 15 rats that were subjected to four different treatment protocols (control group, no treatment; experimental groups, treated with currents of 50 ${\mu}A$, 100 ${\mu}A$ or 300 ${\mu}A$). An experimental 20 mm linear wound was made in each animal and all animals in the experimental groups received microcurrent stimulation once a day for 20 minutes until the day of sacrifice on day 1, day 3 and day 6. An optical microscope was used to determine any histological changes. Results: The experimental results were as follows. 1. In an examination with the naked eye, all groups showed similar changes until the first day. However, from the third day, a little intercellular fluid soaked through wound region in the control group rats. In the experimental group animals, little intercellular fluid soaked through wound region, and swelling and redness did not appear, from the third day. 2. In an examination with histological evaluation, more significant changes were observed in all of the experimental group rats than the control group animals. Especially, a stimulation intensity of 50 ${\mu}A$ caused a more significant effect than the use of the other intensities by day 6 of wound healing. In addition, rapid recovery was observed. Conclusion: It was determined that microcurrent stimulation had a positive effect on wound healing. A stimulation intensity of 50 ${\mu}A$ was more effective than the other intensities (100 ${\mu}A$ and 300 ${\mu}A$) utilized for wound healing. Furthermore, low-intensity microcurrent stimulation was more effective for the purpose of wound healing.

Objective: This study aims to evaluate the efficacy of high-voltage microcurrent therapy in patients with herniated lumbar disc (HLD) presenting radicular or back pain. Method: This is a retrospective study with 33 patients who are complaining pain with HLD findings on magnetic resonance image. Microcurrent therapy was applied to leg or paralumbar area. Treatment was conducted for seven minutes with 250~1000 uA intensity as high as the patients could tolerate via stimulating probe with roller type and the frequency was 60 Hz with a sine wave pulse. The visual analogue scale (VAS) was measured just before and after the treatment. Results: The degree of pain reduction (△VAS) was 1.6 points after treatment on average. The △VAS according to the diagnosis, stenosis, dermatome area, medication, pain site and caudal epidural block was not statistically significant. However, the △VAS according to the number of treatments (< 3, ≥ 3 times) showed a statistically significant difference (p=0.04). Conclusion: High-voltage microcurrent therapy may help reduce lumbar or lumbosacral radiating pain after the procedure. The effect was better when microcurrent was applied three times or more. This result suggests that the microcurrent would have cumulative effect on reducing radicular or back pain in patients with HLD.

Many out patients of the rehabilitation center complaint a pain caused by suffering of MPS, and it brings many different kind of social and ecinomical problems such as medical expenses and the reduction in work efficiency. Therefore, we conducted a research to present a fast and effective treatment to the MPS patients. this research was conducted from November, 1996 to January 1998 with eighteen outpatients who agreed to be the subjects to our reserach. We applied the electric acupuncture on 28 different trigger point on the patients with mostly muscular-skeletal pain and some tender and radiating pain. After the treatment, VRS, VAS, PRI were used to measure the degree of the pain on the patients third and seventh visits, and following results were found. 1. To apply EAP treatment, we acupunctured 6em-Iong needles on Tps region, then the electrodes of pulse generater pg-306 E.S.T were connected on the top of the needles. the electric acupuncture therapy was conducted for 20 minutes with the intensity of 4hz - 60hz(auto wave). The treated electric intensity was the level at which the patients did not feel discomfort. 2. Thirteen out of the 18 participated patients were in their 30s and 40s(72.2%), showing highest frequency. There were more female than male with the ratio of 1 to 1:2. 3. six out of the participated patients (33.3%) had the pain for less then a week, and the average duration of the pain of the participated patients wear 0.8 years. 4. The pain occured mostly in the upper trapezius by 6 part (21.4%), then in the gluteus medius region by 4 part (14.3%). Many of the patients with the pain in the upper back area accompanied varios kind of the referred pains such as radiculopathy, HIVD and Frozen shoulder. 5. MPS occured more frequently on the right side than left side then left side and it seemed to be due to the frequent use of the right hand. 6. There was almost no difference in the measurement of the intensity of the pain right before and after the EAP treatment. Howerver, there was significant decrease in the numerical values of the VAS, and a little bit of decrease in the numerical values of the PRI after the EAP treatment. 7. Based on the results of this present research, it can be concluded that EAP can be used for the treating the myofascial pain syndrome with promptness and safety in most cases.

체외충격파치료술(Extracorporeal Shock Wave Therapy, ESWT)은 보존적인 치료가 어려운 근골격계 난치성 통증 치료 뿐 아니라 심혈관계 질환까지 적용 분야가 확대되고 있는 혁신적인 치료술이다. 본 연구에서는 국내에서 사용되는 집속형 ESWT 치료기의 성능을 결정하는 충격파 음향 출력의 분포를 조사했다. 분석에 사용된 데이터는 식약처에 등록된 30개 기술 문서를 통해 수집했다. 조사 결과, ESWT 치료기 충격파의 집속 특성은, 초점 거리가 5 mm ~ 65 mm, 초점 폭이 3 mm ~ 30 mm, 초점 깊이가 4 mm ~ 108 mm 범위에서 변화하고 있다. 충격파의 최대 양압(P+)는 7 MPa ~ 280 MPa, 초점에서 에너지 밀도 Energy Flux Density(EFD)는 0.0035 mJ/㎟ ~ 35 mJ/㎟, 펄스당 에너지(E)는 0.737 mJ ~ 80.86 mJ로 매우 넓은 범위에서 분포하고 있다. P+ 및 EFD 상관성 분석에 포함된 모든 국내산 PE 방식 제품(5개) 및 1개의 EM 방식 국산 치료기는 P+ 및 EFD가 통상적인 범위를 크게 벗어나고 있으며, 예상되는 상관성을 따르지 않고 있어, 데이터의 신뢰성을 인정하기 어려운 상태이다. 음향 출력의 값에 신뢰성을 부여하기 어려운 경우, 식약처에서 인정하는 시험 검사 기관을 통해 사후 시험 검사 및 관리가 요구된다. 충격파 음향 출력에 대한 통과 기준이 치료기의 적응증에 대한 임상 시험 결과를 근거로 설정될 수 있도록 식약처의 규정 및 가이드라인 개선이 필요하다.
