An adequate location of the reimplanted coronary arteries is one of the most important prognostic factors for an arterial switch operation for treating TGA (transposition of great arteries). We report here on a case of malposition of the reimplanted coronary artery in a 14-year-old boy who had undergone an arterial switch operation. He had chest pain and dyspnea on exertion. The imaging study showed that the ostium of the left main coronary artery, which was between the neo-pulmonary artery and the neo-aorta, was compressed by the great arteries. We excised the left main coronary artery with a button incision from the aorta and reimplanted it on the left lateral side of the aorta. The patency of the left main coronary artery os after the operation was good and it was not compressed by the surrounding arteries.

CT scan is reported to have a high risk of cancer due to a relatively high dose among medical radiological examinations. In particular, exposure to radiation to the breast, which is sensitive to radiation, is inevitable during a chest CT scan for female patient. In this study, the dose reduction effect of wearing a compression band during chest CT scans in women was evaluated, and the lifetime attributable risk due to the effective dose exposed during the CT scan was estimated. As a result, when the compression band was used, the effective tube current decreased as the outer perimeter of the chest became smaller, and it was analyzed that the CT dose index and effective dose were also reduced. In addition, the lifetime attributable risk by chest CT scan was found to reduce the cancer risk by 3.2 per 100,000 for all cancers, 0.2 per 100,000 for solid cancer, and 0.8 per 100,000 for breast cancer, based on women in their 30s when using a compression band. It is judged that the risk of cancer can be reduced through the use of appropriate scan parameters and dose optimization measures such as compression bands for future CT examinations.

This study examined the effect of the application of Theratainment physical factors on the calf blood pressure, ankle angle, and calf circumference. A research sample consisting of normal female university students in their twenties were divided into hot therapy group (n=20), cold therapy group (n=20), and compression therapy group (n=20). By referring to the previous study, 20-minute hot therapy, 15-minute cold therapy, and 30-minute compression therapy with 100mmHg intensity was applied. The therapy was applied to left-side lower limb, followed by the application on the right-side lower limb after an hour of resting time. The calf blood pressure, ankle angle, and calf circumference of each group was assessed. In the study results, hot therapy and compression therapy showed a statistically significant difference on the decrease of blood pressure and increase of ankle angle (p<.05), but cold therapy produced no statistically significant difference. None of the three groups showed a statistically significant difference on the calf circumference. Hence, hot therapy and compression therapy is recommended for reducing calf blood pressure and increasing ankle angle related to the calf. These therapies are expected to be used for solving diverse problems of lower limbs.

동아시아의 19세기는 근대화 물결 안에서 변화의 시대였다. 중국, 한국, 일본은 식민지적 압박가운데 정치적 위기를 대면하였고 선진 문물과 기독교는 사회, 문화, 종교, 사상의 변화를 가져왔다. 신종교운동도 각 나라에서 다양한 형태와 철학으로 등장하였다. 이들의 근본적인 사상은 일반적으로 불교, 유교, 도교, 신교, 샤머니즘과 연관되어 있었다. 근대한국이 정치적 혼란을 겪을 때 여러 신종교들이 1860년을 전후로 나타났다. 나중에 천도교가 된 동학, 증산계, 대종교, 원불교 가운데 증산계 계통의 대순진리회는 사회-종교적인 영향력 차원에서 한국에서 가장 성공적인 신종교 운동이다. 그들은 상제가 스스로 구천에서 혼탁한 삼계를 회복하기 위해 직적 내려왔음을 따르고 있다. 그렇다면, 구천상제에 대한 가르침이 어떻게 이해되고 있을까? 대순진리회의 근본적인 우주관은 무엇일까? 또, 이것이 일본의 유명한 천리교와 중국(대만)의 대규모 일관도와 어떻게 구분될까? 이 논문은 청계탑의 상직적인 콘셉트 안에서 대순의 상제관과 우주관의 관계를 이해하고자 대순의 경전격인 전경, 현무경, 예화들인 심우도, 사신도, 12지신도 등을 탐구할 것이면 이 한국의 대표적인 신종교의 우주관을 천지공사와 후천의 가르침과 연관하여 논리적으로 접근해석 할 것이다.

Purpose: We wanted to evaluate the surgical results of early mobilization after rigid fixation of small coronoid fracture using the tension band technique Materials and Methods: Eight cases of coronoid fracture were fixed with the tension band technique and using K-wire and wire through the medial approach. All the cases were Regan-Morrey type 2. According to O'Driscoll, they were classified as 5 cases of the tip type (subtype 2) and 3 cases of the anteromedial type (1 case of subtype 2, and 2 case of subtype 3). The associated collateral ligament injuries (6 cases) and radial head/neck fractures (4 cases) were managed simultaneously. After immobilization for 5~7 days, active ROM exercise with a fitted hinge brace started and continued till postoperative 6 weeks. The patients were assessed for pain, ROM and functional disability using the Mayo elbow performance score (MEPS) at an average of 11 months (range: 6~28 months). The ulnar nerve symptoms were also investigated. Results: We observed solid union in all the coronoid fractures without hardware failure. An average of 2.2 wires (range: 2~4) were used. The mean extension was $3^{\circ}$(range: $0^{\circ}\sim25^{\circ}$), the mean flexion was $137^{\circ}$(range: $130^{\circ}\sim140^{\circ}$), the mean pronation was $69^{\circ}$(range: $45^{\circ}\sim90^{\circ}$) and the mean supination was $78^{\circ}$(range: $45^{\circ}\sim90^{\circ}$). The mean MEPS was 96 (range: 65~100). Ulnar nerve symptoms occurred at postoperative one day and persisted in one patient with the terrible triad of taking radial head excision and residual medial instability. Conclusion: The tension band technique uses easily obtained, economic K-wires and the wire was strong enough to permit early elbow ROM exercise and the technique might improve the elbow function. It was especially useful for fixation of multiple small fragments.

In this study, a survey on the wearing satisfaction of commercial men's upper body correction underwear was conducted targeting mildly obese men in their twenties, and it was intended to suggest improvement points for the correction underwear. The product used for the study was Adapt's 95 PROBLEM, and 15 subjects were selected as males in their 20s with a BMI of 25-30 (mild obesity). As a result, men's awareness and interest in corrective underwear were low. In the wearing satisfaction survey, 74% of those who answered negatively that it was uncomfortable to wear and take off. In terms of pressure relief, 60% of those who felt the pressure was strong at the beginning, but as time passed, they got used to it and answered that there was no major inconvenience. However, with regard to digestion after a meal, 40% of the subjects felt that the pressure interfered with digestion. There were many deficiencies in terms of functionality, with more than half of those who responded negatively with regard to stuffiness and heat, and many negative opinions regarding sweat absorption and discharge. In the visual section, positive reaction was shown in chest, side waist and front waist correction, and among them, the front waist had the highest score. In conclusion, it seems that functional parts related to heat and sweat must be improved in consideration of the stuffiness and indigestion brought about by excessive pressure for men's upper body correction underwear.

This study analyzed the fabric and product size of the burn patient's custom compression garment and measured the pressure applied by the garment to assess whether proper pressure is being delivered for treatment. The test clothes were presented to the market by body size and commissioned with the same design. The subjects selected four people close to the average body size of men in their 20s determined by 7th Size Korea. The experiment was conducted by wearing a compression suit, performing activities and measuring changes in the pressure of the garment according to changes in posture. The fabric used for the compressive clothing was not ruptured even at 216 kPa, the elasticity recovery rate was measured between 80.5 and 94.5%. The product dimensions of the experimental clothing varied by up to 8cm from brand to brand, requiring the standardization of compression clothing. The experiment showed that four types of compression suit varied in pressure, and the pressure range, excluding the gastric arm (17.9mmHg), was between 2.5-14.1mmHg, which failed to meet the level of pressurization for treatment purposes. The clothing pressure in the chest area dropped when performing movements rather than standing still. This was interpreted to be a result of reduced the adhesion of the compression suit during operation. The peak pressure (31.68mmHg) and the lowest pressure (2.2mmHg) was noted in the scapula, indicating that no pressure was being transmitted on the vertebrae. The pressure of the garment on the right shoulder blade was elevated in a supine position. Because much time is spent laying down, it is necessary for the pattern design to accommodate for the increased clothing pressure on the shoulder blades. Standardization of the level of pressurization for burn patient's custom-made pressure suits for each stage of treatment is urgently required.

Purpose: We compared three chest compression methods to find an efficient method for performing infant cardiopulmonary resuscitation (CPR) for single rescuers and improving chest compressions quality. Methods: Thirty new marine police trainees at the Korea Coast Guard Education Institute were tested for five sessions using three methods of single rescuer infant CPR: two-finger chest compression, two-thumb encircling chest compression, and two-finger support chest compression. Results: The depth, accuracy, and number of compressions per minute of resuscitation were analyzed for the above three methods. The depth of two-finger chest compression, two-thumb encircling chest compression, and two-finger support chest compression was 3.53±0.20cm, 4.10±0.13cm, and 4.22±0.15cm, respectively. Accuracy was 23.86±12.59%, 54.11±10.8%, 71.55±18.81%, respectively, while the time for one cycle of 30 chest compression was 16.01±10.5 seconds, 16.45±0.85 seconds, and 16.56±0.91 seconds, respectively. Chest compression interruptions were 6.59±0.78 seconds, 7.17±0.37 seconds, and 6.97±0.35 seconds, respectively. The interruptions were consistent with the range of 5-10 seconds suggested by the American Heart Association. Conclusion: When one rescuer performs CPR for an infant in cardiac arrest, a comparative analysis of three methods showed that two-thumb encircling chest compression is the best for accuracy and efficiency of chest compressions.
