전자내시경의무기록을 위한 내시경 보고서

조유경 대한소화기내시경학회 2010 Clinical Endoscopy Vol.41 No.4

내시경 분야에서 전자내시경의무기록 시스템은 간단한 내시경 결과보고서의 작성을 넘어 포괄적인 내시경실 관리시스템으로 발전하고 있다. 전자내시경의무기록 시스템은 내시경의사의 효율뿐 아니라 내시경실 관리의 효율을 높일 수 있다. 전산화된 내시경기록은 임상연구와 질 관리가 가능하도록 내시경결과의 데이터베이스 생성을 가능하게 한다. 그러기 위해서는 내시경 보고서의 구조를 계획할 때부터 표준 보고서의 형식을 표준화된 용어를 선택하여 결과를 입력하는 것이 중요하다. 이미 최소표준용어가 내시경의 전산기록을 위해 개발되어 사용되고 있다. 권장 내시경보고서의 사용과 양질의 영상기록은 내시경 질 관리 면에서도 중요하다. Electronic medical record systems for endoscopic data have evolved from simple endoscopy report generators to endoscopy unit managers. These systems may improve patient care and enhance endoscopy unit efficiency and productivity. Regarding endoscopists, the introduction of automated endoscopic reporting using endoscopic electronic medical records should permit database establishment. The systematic development of the structure and content of endoscopic reports is mandatory before it is possible to create large, clinically useful databases of endoscopic reports. An accurate endoscopic report is based on the use of standard terminology, a standard classification method, and image and video recordings. The minimal standard terminology was developed as a minimum list of terms that could be included in a computer system for endoscopic reporting. A standard framework of endoscopic reports using standard terminology and a minimal checklist of endoscopic images are also needed for quality assurance.

Predictors of spontaneous viral clearance and outcomes of acute hepatitis C

조유경,김영남,송병철 대한간학회 2014 Clinical and Molecular Hepatology(대한간학회지) Vol.20 No.4

Background/Aims: This study evaluated the predictors of spontaneous viral clearance (SVC), as defined by twoconsecutive undetectable hepatitis C virus (HCV) RNA tests performed ≥12 weeks apart, and the outcomes of acutehepatitis C (AHC) demonstrating SVC or treatment-induced viral clearance. Methods: Thirty-two patients with AHC were followed for 12-16 weeks without administering antiviral therapy. Results: HCV RNA was undetectable at least once in 14 of the 32 patients. SVC occurred in 12 patients (37.5%), amongwhom relapse occurred in 4. SVC was exhibited in 8 of the 11 patients exhibiting undetectable HCV RNA within 12 weeks. HCV RNA reappeared in three patients (including two patients with SVC) exhibiting undetectable HCV RNA after 12weeks. SVC was more frequent in patients with low viremia than in those with high viremia (55.6% vs. 14.3%; P =0.02),and in patients with HCV genotype non-1b than in those with HCV genotype 1b (57.1% vs. 22.2%; P=0.04). SVC was morecommon in patients with a ≥2 log reduction of HCV RNA at 4 weeks than in those with a smaller reduction (90% vs. 9.1%,P<0.001). A sustained viral response was achieved in all patients (n=18 ) receiving antiviral therapy. Conclusions: Baseline levels of HCV RNA and genotype non-1b were independent predictors for SVC. A ≥2 log reductionof HCV RNA at 4 weeks was a follow-up predictor for SVC. Undetectable HCV RNA occurring after 12 weeks was notsustained. All patients receiving antiviral therapy achieved a sustained viral response. Antiviral therapy should beinitiated in patients with detectable HCV RNA at 12 weeks after the diagnosis.

Ethanol Production from Seaweed, Enteromorpha intestinalis, by Separate Hydrolysis and Fermentation (SHF) and Simultaneous Saccharification and Fermentation (SSF) with Saccharomyces cerevisiae

조유경,김민지,김성구 한국생물공학회 2013 KSBB Journal Vol.28 No.6

Ethanol productions were performed by separatehydrolysis and fermentation (SHF) and simultaneous saccharificationand fermentation (SSF) processes using seaweed,Enteromorpha intestinalis (sea lettuce). Pretreatment conditionswere optimized by the performing thermal acid hydrolysisand enzymatic hydrolysis for the increase of ethanol yield. The pretreatment by thermal acid hydrolysis was carried outwith different sulfuric acid concentrations in the range of 25mM to 75 mM H2SO4, pretreatment time from 30 to 90 minutesand solid contents of seaweed powder in the range of 10~16% (w/v). Optimal pretreatment conditions were determinedas 75 mM H2SO4 and 13% (w/v) slurry at 121oC for 60 min. For the further saccharification, enzymatic hydrolysis was performedby the addition of commercial enzymes, Celluclast1.5 L and Viscozyme L, after the neutralization. A maximumreducing sugar concentration of 40.4 g/L was obtained with73% of theoretical yield from total carbohydrate. The ethanolconcentration of 8.6 g/L of SHF process and 7.6 g/L of SSFprocess were obtained by the yeast, Saccharomyces cerevisiaeKCTC 1126, with the inoculation cell density of 0.2 g dcw/L.

조유경,원나래,권형일,이병현 중앙대학교 학교체육연구소 2017 Asian Journal of Physical Education of Sport Scien Vol.5 No.3

The sport instructors for elderly people are members of two different organizations: National Health Insurance Service(NHIS) and the Korea Council of Sports for All(KOCOSA). Altough these are the ones responsible for the health and leisure activity of elderly people in Korea, their organizational psychological variables were rarely studied. Thus, the purpose of this study was to compare job identity, organizational identification, and perceived professionalism of sports instructors for elderly people according to employment types(NHIS vs. KOCOSA). Total of 272 completed questionnaires were collected from instructors who taught elderly people in Seoul. The results of the study are as follows. First, there were statistically significant differences in the sub-factors of job identity. It was found that NHIS instructors had a higher occupational identity than those of the KOCOSA instructors. Second, there were significant differences in the subfactors of professionalism. The instructors in NHIS had higher professionalism than the ones in KOCOSA. Third, there was a significant difference in organizational identity. The instructors in NHIS had higher organizational identity than the instructors of KOCOSA. 현재 국내에는 국민건강보험공단에 소속되어 어르신의 생활체육을 지도하는 지도자와 국민생활체육회에 소속되어 어르신을 지도하는 지도자로 나뉘어 있다. 이 두 조직에 소속되어 어르신을 지도하는 체육지도자들은 국내 어르신들의 건강과 여가를 책임지고 있는 중요한 인력임에도 불구하고 이들에 대한 조직심리학적 연구가 충분히 되어있지 않은 실정이다. 따라서 본 연구에서는 노인스포츠지도사의 고용형태에 따른 직업정체성과 전문성인식 및 조직정체성을 비교 분석하고자 하였다. 서울 지역에 근무 중인 노인스포츠지도자들을대상으로 총 272개의 설문을 수집하였다. 연구를 통해 다음과 같은 결론을 얻었다. 첫째, 직업정체성의 하위요인 모두 집단 간 유의미한 차이가 있는 것이 나타났으나, 건강백세운동 교실 강사들이 어르신전담체육지도자들보다 더 높은 직업정체성을 가진 것이 확인되었다. 둘째, 전문성인식의 하위요인 모두 집단 간 유의미한 차이가 있는 것이 나타났으나, 건강백세운동 교실 강사들이 어르신전담체육지도자들 보다 더 높은 전문성 인식을 가진 것이 확인되었다. 셋째, 조직정체성에 대한 집단 간 유의미한 차이가 있는 것이 나타났으나, 건강백세운동 교실 강사들이 어르신전담체육지도자들 보다 더 높은 조직정체성을 가진 것이 확인되었다.

조유경,최성호,한옥규,박정현,최창원 경상대학교 농업생명과학연구원 2016 농업생명과학연구 Vol.50 No.5

우리는 심각한 열스트레스 및 서로 다른 사료 에너지 급여가 사료 소화율 변화에 미치는 영향과 심각 한 열스트레스 조건에서 유지를 위한 에너지 요구량을 설정하기 위해 한우 육성기 거세우 4두(평균체중 200±11.7kg)를 이용하였다. 사료 처리는 서로 다른 에너지 공급을 위해 4 시험구(TDN 기준, 쾌적한 상태 하에서 한국사양표준 한우 육성우 에너지 요구량의 100%(대조구), 심각한 열스트레스 하에서 에너 지 100%(E100), 115%(E115), 130%(E130)로 나누어 4×4 라틴 방각법으로 수행하였다. 온도 및 습도에 노출한 열스트레스 조건을 위해 대조구는 쾌적한 온습도지수(THI)=71.5, 나머지 3개 처리구는 THI=81.4로 심각한 스트레스 수준으로 설정하였다. 심각한 열스트레스는 진정 건물소화율을 유의적으 로(p<0.05) 감소시켰으며(대조구 81.5 vs E100 79.1, E115 77.0 및 E130 76.0%), 사료에너지 공급 수 준의 증가는 건물소화율의 감소를 가져오는 것으로 나타났다. 심각한 열스트레스 및 서로 다른 사료 에 너지 급여 수준은 혈중 생리대사물질 함량 및 체온 변화에 유의적인 영향을 미치진 않았다(p>0.05). 본 연구를 통해 심각한 열스트레스 하에서 육성기 한우거세우의 유지를 위한 에너지 요구량은 Y=0.235X+115.03과 같은 산정식으로 계산될 수 있으며, 이러한 결과는 육성기 한우거세우에게 열스트 레스 하에서 체중변화없는 유지 에너지 요구량을 만족시키기 위해서는 현재 한국사양표준 대비, 사료 에너지 15.03%를 더 공급해야 할 것으로 판단된다. Four growing Hanwoo cattle weighing 200±11.7kg were used within 4×4 Latin square design to establish nutrient requirements for Hanwoo growing steers under severe heat stress. The steers were fed four different energy level diets; 100%(control), 100%(E100), 115%(E115) and 130%(E130) of energy levels of growing Hanwoo steers based on total digestible nutrient level suggested by the Korea Feeding Standard for Hanwoo using timothy hay and commercial concentrate. The steers in the control were housed with no stress, whereas the steers in the other groups were under severe heat stress. The severe heat stress significantly decreased(p<0.05) true digestibility of dry matter(i.e. control 81.5% vs E100 79.1, E115 77.0 and E130 76.0, respectively). The severe heat stress and different energy intake levels did not affect blood physiological metabolites and body temperature of the growing steers. Based on changes in average daily gain by different energy intake level, the equation(Y=0.235X+115.03) of energy requirement of growing Hanwoo steers without changes in body weight was calculated, indicating that, compared with the present energy intake suggested by Korean feeding standard, 15.03% of dietary energy for maintenance of growing Hanwoo steers under severe heat stress should be increased.

조유경,최호정,이기자,이영원 한국임상수의학회 2020 한국임상수의학회지 Vol.37 No.6

The aims of this study were to describe the appearance and size of the normal canine prostate using magnetic resonance (MR) imaging and to calculate the apparent diffusion coefficient (ADC) values. MR images were obtained from seven intact male beagle dogs using a 1.5 T MR unit. The sequences included pre- and post-contrast T1- and T2-weighted imaging with and without fat saturation. The signal intensity of the prostate was compared with the adjacent musculature, fat, and urine in the urinary bladder. We recorded the mean prostatic length, width, and height and the length of the sixth lumbar vertebral body (L6). In addition, the prostatic length (rL), width (rW), and height (rH) ratios to L6 were calculated. Diffusion-weighted images of the prostate were obtained and ADC values were calculated. The prostate was bilobed and oval-shaped, homogenous on T1-weighted images, and heterogeneous with radiating lines on T2-weighted images. Post-contrast T1-weighted sequences showed contrast enhancement of the central and radiating striations. The prostatic capsule was clearly identified on post-contrast T1-weighted images with fat saturation. The ADC values were 1.72-2.04 × 103mm2/sec (mean, 1.88 × 103mm2/sec). Knowledge of the normal appearance of the prostate on MR images is essential to assess prostatic diseases in dogs.

Esophageal manometry is the gold standard test for diagnosing primary esophageal motility disorder. With the various metrics of the high-resolution esophageal manometry, the Chicago classification provides a standard approach for the manometric diagnosis of esophageal motor disorders. In the Chicago classification, the esophagogastric junction dysfunction is an important major motor disorder, which includes achalasia subtypes and esophagogastric junction outflow obstruction. Esophagogastric junction outflow obstruction is defined manometrically as normal or weak esophageal peristalsis with incomplete relaxation of the lower esophageal sphincter. It is a heterogeneous disorder and usually has a benign clinical course. The small portion of an esophagogastric junction outflow obstruction is early or variant achalasia. In such cases, treatments directing the lower esophageal sphincter, such as balloon dilatation or per oral endoscopic myotomy, may be necessary. An adjunctive high-resolution manometry provocation test or other esophageal function tests, such as timed barium esophagogram, can help select those patients and predict the treatment outcomes.
