Objective: We aimed to evaluate the clinical and imaging factors associated with hemorrhagic complications and patient discomfort following ultrasound (US)-guided breast biopsy. Materials and Methods: We prospectively enrolled 94 patients who were referred to our hospital between June 2022 and December 2022 for US-guided breast biopsy. After obtaining informed consent, two breast radiologists independently performed US-guided breast biopsy and evaluated the imaging findings. A hemorrhagic complication was defined as the presence of bleeding or hematoma on US. The patients rated symptoms of pain, febrile sensation, swelling at the biopsy site, and dyspnea immediately, 20 minutes, and 2 weeks after the procedure on a visual analog scale, with 0 for none and 10 for the most severe symptoms. Additional details recorded included those of nausea, vomiting, bleeding, bruising, and overall satisfaction score. We compared the clinical symptoms, imaging characteristics, and procedural features between patients with and those without hemorrhagic complications. Results: Of 94 patients, 7 (7%) developed hemorrhagic complications, while 87 (93%) did not. The complication resolved with 20 minutes of manual compression, and no further intervention was required. Vascularity on Doppler examination (P = 0.008), needle type (P = 0.043), and lesion location (P < 0.001) were significantly different between the groups. Patients with hemorrhagic complications reported more frequent nausea or vomiting than those without hemorrhagic complications (29% [2/7] vs. 2% [2/87], respectively; P = 0.027). The overall satisfaction scores did not differ between the two groups (P = 0.396). After 2 weeks, all symptoms subsided, except bruising (50% 2/4 in the complication group and 25% [16/65] in the no-complication group). Conclusion: US-guided breast biopsy is a safe procedure with a low complication rate. Radiologists should be aware of hemorrhagic complications, patient discomfort, and overall satisfaction related to this procedure.

Purpose: Many factors influence the occurrence and severity of geriatric trauma, and regional weather is regarded as one factor that influences geriatric trauma. In this study, to predict the type, severity, and incidence of geriatric trauma patient, we analyzed the influence of regional weather on geriatric trauma. Methods: The subjects of our investigation were trauma patients over sixty-five years of age who visited the Emergency Department (ED) of Yeungnam University Hospital during a one-year period. We retrospectively reviewed the medical charts of 436 geriatric trauma patients, and the data were analyzed by using SPSS 12.0 for Window. The weather was based on data from the Korea Meteorological Administration. Results: The average age was 72.8 years old, and the ratio of males to females was 1:1.1. The mean spell out ISS was 10.8, and no difference was found between males and females. Slips were the most common cause of trauma. The largest numbers of aged trauma patients, 46, visited the ED in May, and the smallest number of such patients, 24, visited the ED in December. In addition to, summer saw the largest number of aged trauma patients. The type of trauma, the Injury Severity Score, and the number of patients had no relationship with season. On sunny days, the ISS was larger in patients who had hypotension and who had tachycardia. On rainy day, the ISS was larger in male patients and cultivator accident patients. The number of patients was larger on partly cloudy days. Conclusion: In spring and summer and on partly cloudy days, we must be prepared to treat aged traumatized patients in the E.D. On rainy days, visual sensation, tactual sense, and acoustic sense must be closely examined. In addition,on rainy day, aged male traumatized patients or cultivator accident patients must to be closely observation.

Backgrounds : Recently, commercial indirect moxibustion has been widely used as a substitute for traditional indirect moxibustion by clinicians due to its convenience in using. But, there has been lack of studies about the similarity of thermal stimulation between commercial indirect moxibustion and traditional indirect moxibustion. Objectives : To demonstrate commercial indirect moxibustion can substitute for traditional indirect moxibustion by comparing thermal stimulation between the two. Methods : We measured bottom temperature of commercial indirect moxibustion and traditional indirect moxibustion with various thicknesses of ginger and garlic. A clinical trial was performed on 18 healthy subjects to evaluate thermal stimualtion. The subjects were randomly assigned into two groups, traditional indirect moxibustion with ginger and garlic. The skin temperature and heating time were measured. They received moxibustion therapy with commercial indirect moxibustion and traditional indirect moxibustion according to their groups. Acupoint Chogcoe($LU_6$), Zusanli($ST_{36}$) and Tianshu($ST_{25}$) were used in each group for 3 times. Results : There was no difference in bottom temperature among commercial indirect moxibustion, traditional indirect moxibustion with 2mm ginger and 3mm garlic. No major difference was detected in the subjects' baseline data. There was no difference in skin temperature and heating time among these 3 type of moxibustions. Also, No major difference was detected in VAS score of thermal stimulation and frequency of burns among these 3 type of moxibustions. But, most subjects regarded their sensation weren't identical because of its own distinct characteristics. Conclusions : Commercial indirect moxibustion, traditional indirect moxibustion with 2mm ginger and 3mm garlic have same thermal stimulation. Thus, commercial indirect moxibustion can substitute for traditional indirect moxibustion.

This study was conducted to evaluate the differences in external appearances and functional qualities between the slacks which were patterned on existing designs and on a new design in order to improve on their level of comfort of ready-made clothes for abdominally fat women. Five abdominally fat women in their 60's were chosen as experimental participants. Twenty-four external evaluation items, and seven different actions involving six moving parts of the body were investigated with a 5-level scale in the repeated wearing test. The results were analyzed by statistical methods. The newly designed pattern in this study was definitely superior to the other two patterns(L-type and K-type) on the external appearance evaluation. The newly pattern removed a waist belt and a dart from the front part of the garment and gave surplus space around the waist. It prevented superfluous wrinkles at the abdominal region and thighs. The superfluous wrinkles at the side regions also disappeared due to the length (inseam) reduction from waist to crotch. The newly pattern made the center-line of the back side slightly sloped to the main pattern in order to remove the drooped line. The newly pattern showed the highest score in the functional test of several actions. It was due to the reduction of the length from waist to crotch as well as the belt width. It made waist-line movement better, and made it easier and more comfortable to sit down. The newly pattern also showed the highest score in the functional test classified by specific movements of parts of the body for the same purpose. The slacks which were made of elastic materials showed better results than the non-elastic ones on external appearances and functional test items. It showed that the elastic materials played a better role in the increase of functional action of abdominally fat, aged women. This study suggests that the newly designed slacks pattern could give abdominally fat, aged women better external features and a more comfortable fitting sensation. As well, the results were significant as basic data to produce ready-made and/or tailer-made garments.

The goats raised in the barn are usually fed on fresh grass. As dry forage can be stored for long periods in large amounts, dry forage feeding makes it possible to feed large numbers of goats in barns. This review explains the physiological factors involved in suppressing dry forage intake and the cause of drinking following dry forage feeding. Ruminants consume an enormous amount of dry forage in a short time. Eating rates of dry forage rapidly decreased in the first 40 min of feeding and subsequently declined gradually to low states in the remaining time of the feeding period. Saliva in large-type goats is secreted in large volume during the first hour after the commencement of dry forage feeding. It was elucidated that the marked suppression of dry forage intake during the first hour was caused by a feeding-induced hypovolemia and the loss of $NaHCO_3$ due to excessive salivation during the initial stages of dry forage feeding. On the other hand, it was indicated that the marked decrease in feed intake observed in the second hour of the 2 h feeding period was related to ruminal distension caused by the feed consumed and the copious amount of saliva secreted during dry forage feeding. In addition, results indicate that the marked decreases in dry forage intake after 40 min of feeding are caused by increases in plasma osmolality and subsequent thirst sensations produced by dry forage feeding. After 40 min of the 2 h dry forage feeding period, the feed salt content is absorbed into the rumen and plasma osmolality increases. The combined effects of ruminal distension and increased plasma osmolality accounted for 77.6% of the suppression of dry forage intake 40 min after the start of dry forage feeding. The results indicate that ruminal distension and increased plasma osmolality are the main physiological factors in suppression of dry forage intake in large-type goats. There was very little drinking behavior observed during the first hour of the 2 h feeding period most water consumption occurring in the second hour. The cause of this thirst sensation during the second hour of dry forage feeding period was not hypovolemia brought about by excessive salivation, but rather increases in plasma osmolality due to the ruminal absorption of salt from the consumed feed. This suggests the water intake following dry forage feeding is determined by the level of salt content in the feed.

본 연구는 국내 음악치료 및 물리치료 분야에서 리듬청각자극(RAS)을 적용하여 수행된 연구를 비교분석하였다. 이를 위해 1999년부터 2018년 11월까지 발표된 학위 논문과 학술지 게재 연구 중 RAS 및 보행기능 관련 주제어를 검색하여 기준에 부합한 45개의 연구를 선정하였고, 세부중재방법과 리듬자극의 유형, 기술된 치료 원리의 측면에서 분석하였다. 분석 결과, 두 영역에서의 연구 모두 일정한 간격의 리듬을 핵심적인 치료 자극으로 사용하고 RAS의 기본 절차를 따른 점에서는 공통적이었지만, 목표기능이나 구체적인 리듬제공방법에 있어서는 차이가 있었다. 음악치료 연구에서는 모두 보행기능이 목표 변인이었던 데 비해, 물리치료 연구에서는 균형이나 근력, 고유수용성감각 등 관련 신체기능이 목표에 포함되었다. 또한 음악치료 연구에서는 다양한 요소를 포함한 '음악'이 리듬자극으로 활용된 반면, 물리치료 연구에서는 메트로놈을 리듬자극으로 활용한 연구가 음악을 활용한 연구보다 많았다. RAS 원리와 관련하여 단순한 기법 설명 외에 동조화와 같이 치료의 원리가 충분히 기술된 연구는 물리치료보다는 음악치료 분야에서 많이 확인되었다. 이러한 결과는 음악치료 연구에서는 리듬과 더불어 음악의 다양한 요소가 보행에 미칠 수 있는 영향이 고려되어 음악의 역할이 적극적으로 활용된 반면, 물리치료 연구에서는 보행에 영향을 미치는 다양한 신체기능에 대한 개입이 포함된 경향이 있음을 보여준다. 두 가지 측면 모두 재활에 있어 중요한 부분임을 고려할 때, 본 연구는 다학제간 연구를 기반으로 한 RAS 연구의 기법의 확장 적용에 대한 시사점을 제시한다고 할 수 있다.

This study was performed to investigate correlation between total body weight loss and local sweat rate and to find out any possible method that can estimate total body weight loss judging from local sweat rate. Twelve adult females were kept at 44 $\pm1^{\circ}C$, 50 ${\pm}5\%$ R.H. (1) Physiological responses such as total body weight loss, local sweat rate, rectal temperature, skin temperature, blood pressure and pulse, (2) micro climate inside garment and (3) subjective sensation were examined. Two types of garment such as long-sleeves with long pants (Type I) and half·sleeves with short pants (Type II) were used to observe the effect of garment types on sweating response. Both clothing weight was equal (132$\pm$3 g/$m^{2}$). The results were as follows: 1. Regardless of the different types, total body weight loss was more interrelated with the sweat rate on forehead than any other parts of the body. Except the forehead, different parts of body with different types of garment influenced on body weight loss quite differently. 2. Total body weight loss was more interrelated with the weight gain of garment than the local sweat rate. 3. Under the environment of 44$\pm1^{\circ}C,\;50{\pm}5\%$R.H., body weight loss during 1 hour of subject clothed and silted was 275.2 g/hr and weight loss per body surface area was 178.9 g/$m^{2}/hr$ Garment types have no influences on total body weight loss. 4. Local sweat rate (mg/7.07 $cm^{2}/hr$) was 208.0,191.0, 133.0, 115.0,81 0, 75.1 and 66.3 on scruff, breast, forehead, forearm, thigh, upper arm, leg respectively No evidence has been found that garment types influenced on local sweat rate (p<0.1). 5. No interrelationships between rectal temperature and total body weight loss, local skin temperature and total body weight loss, and local skin temperature and local sweat rate were found. From this study, some possible method that we can estimate total body' weight loss judging from weight loss of garment. But considering the fact that clothing design factor, the physical characteristics of fabric and environmental factor such as humidity and wind velocity should be concerned in weight loss of garment, it should be studied further whether the total body weight loss can be estimated properly from the weight loss of garment. This experiment suggest that different parts of body with different types of garment can influence on body weight loss quite differently. Therefore, in order to get more precise results, more studies under the diversity of garment types should be done in the near future.

본 연구는 제2형 당뇨병 환자가 인식하고 있는 구강건강 문제를 파악하고, 당화혈색소와 주관적 구강건강상태와의 연관성을 제시함으로써 당뇨병 환자의 전신 및 구강건강증진을 위한 기초자료를 제시하고자 시행하였다. 2012년 1월 9일부터 2012년 3월 9일까지 만 40세 이상 제2형 당뇨병을 가진 환자 174명에게 설문지 조사와 $In2it^{TM}$을 이용하여 당화혈색소를 측정한 결과 다음과 같은 결론을 얻었다. 1. 연구대상자의 구강건강문제를 파악한 결과 구강점막질환 증상 중 '입 안 점막에 염증이 있다'와 '입 안 점막이 아프다', 치주질환 증상 중 '칫솔질 시 잇몸에서 피가 난다', 구강건조증 증상 중 '평상시 내 입 안은 마른다고 느낀다'를 가장 많이 인식하는 것으로 나타났다. 2. 일반적 특성에 따라 주관적 구강건강상태를 분석한 결과, 특히 당뇨병 유병기간이 길수록 입안점막질환과 치주질환의 증상 및 구강건조증 증상을 더 많이 인식하는 것으로 나타났다(p<0.05). 3. 혈당 조절을 위한 건강행동에 따라 당화혈색소 수준을 분석한 결과, 규칙적인 식사를 잘 실천하는 집단에서 당화혈색소 수준이 더 낮은 것으로 나타났다(p<0.01). 4. 주관적 구강건강상태에 따라 당화혈색소 수준을 분석한 결과, '혀에 타는 듯한 느낌이 있다', '칫솔질 시 잇몸에서 피가 난다', '잇몸이 치아 뿌리 쪽으로 내려갔다' 및 '입에서 나쁜 냄새가 난다'를 인식한 집단에서 당화혈색소 수준이 더 높았다(p<0.05). 또한 구강건조증 증상 중 '나는 목이 말라 자다가 일어나 물을 마신다'에 응답한 집단에서 당화혈색소 수준이 더 높았다(p<0.05). 특히 다중선형회귀분석 결과 치주질환 증상은 당화혈색소와 3번째로 강한 연관성을 보인 요인으로 나타났다. 이상의 결과로 볼 때 혈당조절 정도는 다양한 구강건강문제와 관련성이 있으므로 당뇨병 환자를 대상으로 구강관리 프로그램의 적용을 더욱 강화하고, 의료인력의 협진을 통해 구강 내 당뇨합병증을 최대한 감소시켜야 할 것이다.
