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.

Intestinal obstruction is not uncommon in infants. The common causes of intestinal obstruction in the neonatal period are Hirschsprung disease, intestinal atresia, meconium ileus, and intussusception. However, small bowel obstruction caused by a congenital band is very rare. We report a 27-day-old baby who was admitted with abdominal distension and fever. The abdominal X-ray revealed massive bowel dilatation and the contrast gastrografin enema suggested a distal small bowel obstruction. The explolaparotomy showed small bowel entrapment due to an unusual anomalous congenital band.

Purpose: This study was conducted to compare pain, sense, bleeding, and hematoma that patients feel depending on the process of eliminating air of pressure band that was applied to patients after percutaneous coronary intervention (PCI) through radial artery. Methods: It was a nonequivalent control group pretestposttest design to compare pain, sense, bleeding, and hematoma by amount and time of eliminating air of pressure band after PCI through radial artery. Results: On arrival at Coronary Care Unit, meaningful difference didn't exist between pain and sense, however, after two hours of starting eliminating air, the points of pain and sense were meaningfully low (p<.001). Also, there was meaningful difference in reciprocal action between group and time (p<.001). Conclusion: After PCI, the conclusion showed there is positive effect in decreasing wrist pain and sense without any influence of bleeding by eliminating air from patients' pressure bands.

최근 이동전화를 이용한 무선인터넷, IMT-2000의 화상전화서비스 등 무선 Multimedia의 시대가 도래하고 있다. 그러나. 3G 서비스를 시작한 유럽, 일본의 서비스 사업자들은 막대한 앙 설치비용으로 꿈의 이동전화서비스가 활성화되기 전에 자금 압박으로 몸살을 알고 있다. 이동전화서비스는 유한한 자원인 주파수 밴드를 얼마나 효율적으로 사용하느냐가 양사업자들의 성공과 실패를 가름하는 경쟁력의 무기로 작용한다. 이러한 주파수를 효율적으로 사용할 수 있는 방법 중에 몇 년 전부터 스마트안테나가 제조사, 서비스사업자는 물론 학계의 비상한 관심을 모으고 있다. 본 논문에서는 이동전화서비스 사업자 입장에서 스마트안테나를 현장적용 시험을 통해 시스템 용량증대에 효과가 있는지 확인하고자 한다.

Loss of leg muscle and muscle weakness, which are caused by aging, affect muscle function and sense of balance. As a way of preventing seniors from falling, we developed the idea of wearing functional supporters based on graduated compression technique and in the form of a taping supporter. Their impact on power, sense of balance, overcoming fatigue, and subjective wearing sensation was investigated. The following results were obtained. After wearing functional compression supporters, body temperature increased from 24.5 ± 0.5℃ to 26.3 ± 0.6℃. Calf size, which assesses the level of edema, decreased from 26.1 ± 1.8cm to 25.7 ± 1.8cm. The result of dynamic balance test, which helps estimate the fall prevention effect, increased from 6.4 ± 0.9sec to 7.1 ± 0.6sec. Lactate level, which indicates the level of fatigue, decreased from 8.1 ± 0.6mmol/L to 7.3 ± 0.8mmol/L. Standing long jump record, which assesses power, increased from 110.1 ± 3.1cm to 112.0 ± 2.8cm. Standing on one leg with eyes closed, which assesses sense of balance, increased from 4.2 ± 1.1sec to 6.5 ± 0.8sec. Ankle angle, which assesses joint stability, increased from 75.3 ± 4.0° to 80.1 ± 1.7°. In metabolism and physical performance testing, which assesses keep, the score increased from 26.3 ± 1.7 to 28.8 ± 1.2. Muscle supporting score, which assesses joint stability, increased from 7.3 ± 0.6 to 7.8 ± 0.4. In the category of body type, which assesses wearing sensation and body shaping function, the score increased from 5.7 ± 1.4 to 6.4 ± 1.2

In this study, the pulse of radial artery and oxygen saturation are detected using photoelectric plethysmograph method. Using our device designed reflection type, we can detect the reflected light by radial artery and by switching circuit, we can also separate to 625nm band signal and 940nm band signals. The separated signals are converted as a pulse data by the pulse signal processing circuit. In this study, the reflection type of oxygen saturation calculation method is applied instead of the transmission type because of the reflection type sensor is used to measure the radial artery. As a result, we can detect about 97% accuracy of the oxygen saturation compare with the conventional method. For the accurate signals, the wrist band with sensor was designed and fixed on the radial artery. As a result, this wrist band type sensor was applicable to prevent position errors from motion artifact and could increase the accuracy during the measuring.

This study was to decided the proper garment pressure level on the human body parts. Six volunteers (female: 30-40years) put on the same types of bands, a brief, and a non-woven gown. Garment pressure was measured in regular order with the elastic band on the human body parts such as the upper arm, the waist, the thigh, and the calf. At the same time, physiological responses such as the skin blood flow rate on 2 fingers, 7 different skin temperatures, rectal temperature, heat rates, and subjective responses about the pressure sensation, thermal sensation, and humidity sensation were measured and inquired. The results were as follows; 1. The thicker subcutaneous fat thickness, the higher the mean garment pressure on pressurizing the upper arm(p<.001). Also the thicker subcutaneous fat thickness. the thicker the upper arm circumference. 2. Heart rates increased pressured the upper arm and decreased pressured the waist, the thigh, and the calf. The higher the garment pressure, the higher heart rates on all body parts were pressured. Especially lean subjects showed higher physiological load than others. 3. On pressurizing the upper arm, heart rates, rectal temperature, and mean skin temperature were higher than without pressured state and pressured other body parts.4. The proper garment pressure levels were decided 30gf/$cm^2$ for fat people, 20gf/$cm^2$ for others on the upper arms and 24gf/$cm^2$ on the calf.
