본 연구는 특수학교 교사와 일반학교교사의 기본심폐소생술(인공호흡, 심폐소생술) 숙련도를 비교하는데 목적이 있다. 대상자는 특수학교(44명)와 일반학교(48명)에 재직 중인 교사 총 92명으로 선정하였으며, 측정은 마네킨(ResusciAnne w/SkillReporter)을 사용하였다. 자료 처리는 SPSS 12.0 for Windows를 이용하여 측정항목의 평균값(M)과 표준편차(SD)를 구하였고, Komogorov-Smirnov Z-test를 실시하였다. 측정항목의 정확도와 오류율의 차이를 독립표본 t-test와 Mann-Whitney U-test를 실시하였으며, 유의수준(a)은 ,05로 설정하였다. 분석한 결과는 첫째, 교사의 학교구분에 따른 인공호흡 숙련도는 유의한 차이가 없었으며, 교사 성별에 따른 인공호흡 숙련도는 정확도에서 남자가 여자보다 높게 나타났고, 오류는 과다 실시 횟수에서 남자보다 여자가 높게 나타났다. 둘째, 교사의 학교 구분에 따른 심폐소생술 숙련도는 평균 압박속도에서 특수학교 교사가 일반학교 교사보다 빨랐다. 교사 성별에 따른 심폐소생술 숙련도는 유의한 차이가 나타나지 않았다. 이상의 연구에서 볼 때 학교 안전사고를 대비한 학교교사를 대상으로 심폐소생술 교육의 필요성이 강조되어지며, 응급상황시 대처능력을 향상시킬 수 있는 교육프로그램이 마련되어야 된다고 본다.

Purpose : To evaluate the utility of mammography and ultrasonography in study of morphologic differential diagnosis between malignant and benign mass. Materials and Methods : Average age of patients with breast cancer was 48.4 year-old, and that of fibroadenoma was 29.4 year-old. The equipments used for examination were MF-159 high frequency mammography(Bennet Co.) and Acoustic image 5200S. We evaluated mammographic findings about breast parenchymal pattern, calcification, margin and size of the mass associated tumor nature, and ultrasonographic findings about shape, height and width, internal homogenicity and echo pattern, wall contour, boundary echo, and posterior shadow in breast mass. Thirty-seven of mammographic findings and 34 cases of ultrasonogreaphic findings in pathologically proven breast cancer and 34 case of mammographic findings and 71 cases of ultrasonographic findings in breast fibroadenoma were reviewed retrospectively. Results : In mammographic study, the parenchymal patterns of breast cancer according to Wolfe classification were NI(16.2%), PI(24.3%), P@(37.8%), and DY(21.6%) and those in fibroadenoma were NI(3.1%), Pl(11.7%), P2(35.2%),and DY(50%). Mammographic findings about presence of calcification were as follows; only calcification(16.2%), only mass(51.3%), and mass with calcification(32.5%) in breast cancer, and only mass(91.2%), mass with calcification(8.8%) in fibroadenoma. The features of mass margins were classified as ill-defined margin(45.9%), well-defined(5.4%), and well-defined with partial spiculation(48.6%) in breast cancer and ill-defined(20.5%), well-defined(73.5%), and well-defined with partial spiculation(5.8%) in fibroadenoma. The mass were grouped by size; 1-2cm(37.8%), 2-4cm(45.9%), and 4-6cm(16.3%) in breast cancer and 1-2cm(79.4%), 2-4cm(17.6%), and 4-6cm (3.0%) in fibroadenoma. On ultrasonographic study, the shape of masses in breast cancer were lobulated(82.3%),oval(14.7%), and round(3.0%),and those in fibroadenoma were lobulated(14.0%), oval(57.7%), and round(18.3%). The cases that the height was longer than width were 32.3% in breast cancer and 0% in fibroadenoma. The findings about homogenecity and echo patterns were as follows; hypoechoic(52.9%) and mixed(47.1%) in breast cancer and hypoechoic(2.8%), hypoechoic(63.4%), and mixed(33.8%) in fibroadenoma. The margin of masses were smooth in 85.9% of fibroadenoma, and irregular in 73.6% of breast cancer. The boundary echoes of masses and decreased posterior echo shadow were seen only in 61.8% and 55.9% of breast cancer, respectively. Conclusion: The margin and calcifications are more clearly delineated on mammography but breast cancer and fibroadenoma, both are more commonly developed in dense parenchymal pattern(P2+DY),and there findings are easily obscured in mammography. So ultrasoography is very useful in these masses evaluation, especially amoung young patients.

A delayed hemolytic transfusion reaction precipitated by anti-C (rh') is described in a previously transfused 40-year-old man. Seven days after the transfusion of the 7 pints of red cells for anemia due to Mallory-Weiss syndrome, he experienced a fall in hematocrit and hemoglobinuria accompanied by a positive direct and indirect antiglobulin test. Anti-C (rh') was identified in the patients serum by Panel cell screening test.

The incidence of aseptic meningitis infection is ensuing and threatening the health of children. Enteroviruses are the major agents of aseptic meningitis and identification of virus has been a clue to diagnosis and epidemiology. The outbreak of aseptic meningitis occurred in Pusan, 1998. Patients were concentrated from April through November. Children were more susceptible than adults. Among 306 cases of specimens from stool, throat swab tested, only 7.2% were positive on virus isolation, 12 cases from stool and 10 from throat, respectively. All isolated 7 serotypes of viruses represented cytopathic effect on cultured cells. Three types of echovirus 6, 25, 30 and coxsackievirus B2, B3, B4, B6 were identified by neutralizing anti body test. Isolated coxsackievirus and echovirus were observed by an electron microscope with negative staining.

Background: Encapsulating peritoneal sclerosis (EPS) is a serious and often fatal complication of long-term peritoneal dialysis (PD) with severe malnutrition and poor prognosis. We aimed to investigate the incidence and clinical features of EPS in patients on PD. Methods: The data were collected retrospectively from 603 prevalent PD patients in the Kyungpook National University Hospital between August 2001 and July 2011. EPS was diagnosed by the 2000 criteria of the International Society of Peritoneal Dialysis. Results: Eight patients (1.3%) met the diagnostic criteria of EPS. They had at least one of three symptoms: abdominal pain, vomiting and abdominal distension. Mean age of patients was 48.5 (range: 33 to 65) years and 4 were men. Mean duration on PD was 111.7 (range: 23 to 186) months. Seven patients had chronic glomerulonephritis as underlying renal disease, and one patient hypertensive nephrosclerosis. All patients except one had 2 or more episodes of peritonitis, the peritonitis rate being 1/33.7 patient-months in the 8 EPS patients. Six patients were treated with icodextrin solution. Four patients were treated with beta-blocker (cavedilol, 25-50 mg daily). Total parenteral nutrition was used in all patients. Only one patient had elective surgical intervention, adhesiolysis. Four patients were treated with glucocorticoid (0.5~1 mg/kg/day), three with tamoxifen (10-20 mg daily) and three with both. Of the 8 patients diagnosed with EPS, 6 survived and 2 died, an overall mortality rate being 25%. Conclusion: EPS is rare but a serious life threatening complication in patients on long-term PD. To reduce the incidence and mortality of EPS, careful monitoring and intensive therapy may be needed. Keywords: Encapsulating peritoneal sclerosis, Peritonitis, Continuous ambulatory peritoneal dialysis.
TOWARD A NEXT GENERATION SOLAR CORONAGRAPH: DIAGNOSTIC CORONAGRAPH EXPERIMENT

The Korea Astronomy and Space Science Institute (KASI) has been developing a next-generation coronagraph (NGC) in cooperation with NASA to measure the coronal electron density, temperature, and speed simultaneously, using four different optical filters around 400 nm. KASI organized an expedition to demonstrate the coronagraph measurement scheme and the instrumental technology during the 2017 total solar eclipse (TSE) across the USA. The observation site was in Jackson Hole, Wyoming, USA. We built an eclipse observation system, the Diagnostic Coronal Experiment (DICE), composed of two identical telescopes to improve the signal-to-noise ratio. The observation was conducted at four wavelengths and three linear polarization directions in the limited total eclipse time of about 140 seconds. We successfully obtained polarization data for the corona but we were not able to obtain information on the coronal electron temperature and speed due to the low signal-to-noise ratio of the optical system and strong emission from prominences located at the western limb. In this study, we report the development of DICE and the observation results from the eclipse expedition. TSE observation and analysis with our self-developed instrument showed that a coronagraph needs to be designed carefully to achieve its scientific purpose. We gained valuable experience for future follow-up NASA-KASI joint missions: the Balloon-borne Investigation of the Temperature and Speed of Electrons in the Corona (BITSE) and the COronal Diagnostic EXperiment (CODEX).
