Churg-Strauss syndrome is a rare syndrome that is characterized by hypereosinophilic systemic necrotizing vasculitis affecting small- to medium-sized arteries and veins. The manifestations of multiple tracheobronchial mucosal lesion and thrombus of left ventricle are rarely reported in Churg-Strauss syndrome. We report a case of Churg-Strauss syndrome with diffuse tracheobronchial mucosal lesions in a 52-year-old man who developed a left ventricular thrombus after discontinuation of treatment. Bronchial asthma, rhinosinusitis, peripheral eosinophilia, p-ANCA positive, eosinophilic lung infiltration, vasculitis led to a diagnosis of Churg-Strauss syndrome. On bronchoscopic evaluation, diffuse necrotizing mucosal lesions were observed on tracheobronchial tree. With methylprednisolone (125 mg/day), his asthmatic symptoms were well-controlled and eosinophil count and eosinophil cationic protein concentration in peripheral blood maintained in normal ranges over a 20 month period, but he was lost to follow-up. After 12 months from discontinuation of treatment he readmitted with relapsed Churg-Strauss syndrome with left ventricular thrombus. The thrombus gradually disappeared after prednisolone (1 mg/kg/day) and warfarin treatment. (Korean J Asthma Allergy Clin Immunol 2010;30:314-319)

외래에서 혈뇨 환자를 접하게 되면, 환자의 활동성 및 운동 여부를 반드시 확인하고, 혈뇨가 운동으로 유발되고, 운동 중단 후 호전되는지 확인하여야 한다. 그리고 종양, 감염, 약물, 요석, 신염과 운동 유발 혈뇨를 감별하여, 검사의 진행 여부를 결정해야 한다. 하지만 운동 유발 혈뇨가 다른 신장-비뇨기계의 증상 중 하나일 수 있기 때문에 반복적인 혈뇨, 연령 등에 따라 검사가 필요함을 염두해 두어야 한다. Exercise-induced hematuria is a phenomenon occurring in subjects who participate in strenuous exercise. Rapid resolution is an important feature of exercise-induced hematuria. We report here a case of exercise-induced hematuria presenting as gross hematuria Lasting I week in a 19-year-old male patient. Gross hematuria developed after strenuous exercise about 3 years ago. Three months ago, recurrent gross hematuria was Lasting I week, regardless of exercise intensity. Compression of the Left renal vein between the aorta and superior mesenteric artery, without prominent venous collaterals, was detected by computed tomography. However, no abnormalities were detected by renal venography, arteriography or kidney biopsy. Exercise-induced hematuria occurs with a high incidence, but is self-Limiting. In contrast, recurrent and gross hematuria can be associated with bladder carcinoma or vascular abnormality. This should be kept in mind, and urological evaluations such as cystoscopy and angiography are necessary in gross and recurrent hematuria. (Korean J Med 2012;82:95-99)

본 연구의 목적은 미용특성화 고등학교 학생들이 인식하는 미용교사 이미지(성품, 외모, 학업·생활지도, 전문성)가 학생들의 수업태도(실기수업태도, 이론수업태도)에 어떠한 영향을 미치는가를 알아보고, 학생에 대한 미용교사의 이미지에 대한 중요성을 인식하게 하고, 그로 인해 학생들의 수업에 대한 집중성과 효율성을 높이는 기초자료를 제공하는데 기여하고자 하는데 있다. 그 결과, 실기수업태도에 대해 미용교사 이미지인 성품, 외모, 학업·생활지도, 전문성 중 외모가 실기수업태도에 정적인 영향을 미치는 것으로 나타났다. 이론수업태도에 대해 미용교사 이미지인 성품, 외모, 학업·생활지도, 전문성 중 외모가 이론수업태도에 정적인 영향을 미치는 것으로 나타났다. 이 연구의 대상자인 미용과 학생들은 실업계 고등학교이면서 미용을 전공하는 점에서 외모이미지에 높게 반응하는 것으로 보인다. 청소년기엔 외모 가꾸기를 통하여 개인의 특유의 개성을 표현한다거나, 또래문화의 흐름에 동참을 하려하는 경향이 있다. 미용 전공 학생들에게서 교사의 외모이미지에 대한 반응이 높은 것은 이를 반영하며, 특히 외모를 아름답게 가꾸는 미를 배우는 과목의 특성도 영향을 주는 것으로 생각된다. 따라서 미용교사들은 학생들의 적극적이고 능동적이고 바람직한 수업태도를 위해서 여러 가지 이미지는 물론이며 외모에도 미용교사다운 이미지를 관리하는 것에 있어 관심을 가져야 할 것이다. The purposes of this study is to find out how beauty-specialized high school students` recognition of beauty teachers` image influences on class attitude toward both practice-oriented classes and theory-oriented classes, to recognize how important students` recognition of beauty teachers` image is, and to provide fundamental data about how to increase students` concentration and efficiency on classes by using beauty teachers` good image. As a result, appearance has a positive influence on practice-oriented classes among personality, appearance, work·role counselor and specialty. In theory-oriented classes appearance also has a positive influence among personality, appearance, work·role counselor and specialty. The subjects show high response to appearance because they study in a vocational school and major in beauty. In adolescence students tend to express their individuality by taking good care of their appearance and to keep up with peer culture. High response of the students, who major in beauty, to teachers` image by appearance show this fact, and was particularly influenced on their subjects` characteristics that are related with beauty. Therefore, beauty teachers need to have interest not only in several images but also in taking care of a good image as a beauty teacher to make students have enthusiastic and positive class attitude.

Background/Aims: In the Helicobacter pylori (H. Pylori)-negative normal stomach, collecting venules are visible over all the gastric body as numerous minute points evaluated with standard endoscopy. This finding was termed regular arrangement of collecting venules (RAC), and its absence suggests H. pylori gastritis. The aim of this study was to evaluate the correlation between the RAC and rapid urease test. Methods: Two hundred sixty three consecutive adults undergoing upper digestive endoscopy and rapid urease test were included. The lesser curvature of the lower corpus was evaluated for the RAC pattern using a standard endoscope and different hemoglobin index. Two biopsies from the lesser curvature of the antrum and the greater curvature of the body were collected for rapid urease test. Results: H. pylori were detected in 51.3% (135/263) patients. Of the 57 patients with H. pylori-negative normal stomachs 53 patients (93%) had RAC. As a determinant of the normal stomach without H. pylori infection, the presence of RAC had 41.4% sensitivity, 97.0% specificity, 93.0% positive predictive value and 63.6% negative predictive value. Conclusions: RAC-positive finding by standard endoscopy showed high positive predictive value and specificity of H. pylori-negative normal stomach. RAC-positive finding by standard endoscopy could be an useful finding to predict H. pylori negativity. (Korean J Gastroenterol 2011;58:252-257)

Sugar solutions (5%, 10%, 15% and 20%) were tested by seven sensors of Astree E-Tongue for selecting a sensor for sweetness. NMS sensor was chosen as a sensor for sweetness among two sensors (PKS and NMS sensors selected in first stage) by considering precision, linearity and accuracy. Sugar, fructose, glucose and xylitol (5%, 10% and 15%) were tested by E-tongue. The principal component analysis (PCA) result by E-Tongue with seven sensors at 5% concentration level of four sweetners was not satisfactory (Discrimination index was -0.1). On the other hand, the relative NMS sensor response values were derived as 1.08 (fructose), 0.99 (glucose) and 1.00 (xylitol) comparing to sugar. Only the E-Tongue relative glucose response 0.99 was different from 0.5~0.75 of the relative sweetness range reported as the human sensory test results. Considering the excellent precision (%RSD, 1.53~3.64%) of E-Tongue using NMS single sensor for three types of sweeteners compared to sugar in the concentration range of 5% to 15%, replacing sensory test of sweetened beverages by E-Tongue might be possible for new product development and quality control.

공기중 음향 임피던스의 차이로 생기는 에너지 손실을 High Power 초음파 Pulser Reciver, PRE-AMP, 고감도의 탐촉자로 보완하여 비접촉식으로 초음파 탐상을 가능하게 하는 탐상 방법이다. 일반적으로 초음파 탐상을 할 때 접촉 매질(couplant)을 사용하는 접촉식 기법을 적용하여 탐상을 수행하지만 접촉매질 없이도 초음파 탐상이 가능한 방법이다. NAUT는 초음파의 송신 및 수신이 안정된 상태에서 이루어지므로 기존의 접촉식 탐상으로는 불가능하였던 고온, 저온의 물질이나 시험편의 표면이 거친 부분, 좁은 지점 등에서도 탐상이 가능하다. 따라서 접촉식 방식으로는 제약이 많았던 부분들에 대해 친환경 자동차용 Brake pad에 대한 NAUT 탐상 기술을 적용시켜 그 실용화를 확인하였다. The NAUT technique allows non-contact ultrasonic testing in air. If the NAUT technique can be applied, not only ultrasonic testing in air with no couplant would be possible, but also the stable transmission and reception of ultrasonic waves, which would thus enable ultrasonic testing of hot or cold materials, or rough surfaces of specimens that could not be tested with conventional-contact ultrasonic testing techniques. By trying NAUT for Brake lining pad specimens, the applicability of NAUT in these areas was observed, and the results from the waveforms of parts of the specimens were analyzed. For the Brake lining pad specimen, the ultrasonic transmittance was highest at the part, regardless of the thickness and location of the specimen. These findings confirmed the practicality of NAUT.

Despite the splendid development of medicine, traditional alternative remedies have been widely used in Korea for a long time. Especially, the extract of elm bark is typical, common and easily obtained in a daily life. A scientific name of elm is Ulmus davidiana var. japonica. Although the study of pharmacologic effect and side effect is underway, the results are not yet enough to be applied in practice. Nevertheless, many people have the extracts of elm bark on expecting the improvement of health. We experienced a case of acute toxic hepatitis and acute kidney injury after complementary medication. She was a 48-year-old female patient who ingested 3-4 cups of extracts per day for 10 days to improve her health until admitted due to nausea, vomiting, and fatigue. The case report can suggest that ingestion of complementary medicine (elm bark root extracts) can be a cause of acute toxic hepatitis and acute kidney injury.
