The effect of cornsilage and ricestraw, cornsilage and hay, cornsilage on milk yield, milk fat, live weight and economic analysis were studied by ad libitum experimental design. Four difference treatments were tested with the following experimental rouhage per day in forage basis: corn silage + rice-straw (25㎏ + 5㎏), corn silage + hay (25㎏ + 3㎏), corn silage + hay (20㎏ + 2㎏), corn silage (30㎏). Thereon, concentrate was fed according to milk production during the experimental period. The results obtained are as follows: 1. Dry matter intake per day during the experimental period among four treatments showed little difference. 2. The animal in treatment T2 tended to give higher milk yield than those in treatment C. T1, T3, but the difference was not significant statistically. 3. The cows in treatment T3 gave milk of higher fat content than those in treatment C, T1 or T2, but the difference was not significant statistically. 4. Treatment T1 gave the most increase in body weight following by treatment T2, C, and Treatment T3 gave the least increase in body weight during the experimental period but the difference was not signifficant. 5. Treatment T1 gave the most income in economic analysis followed by treatment T1, T3, and treatment C gave the least income in economic analysis during the experimental period.

Gastric outlet obstruction (GOO) results from obstructing lesions in the region of the pyloric channel. In neonates, hypertrophic pyloric stenosis (HPS) is the most common cause while peptic ulcer is a rare cause. Neonatal gastric ulcer is relatively frequent in preterm newborn babies or in neonates treated in intensive care units. In healthy neonates, mucosal ulcers are associated with stressful conditions. In gastric ulcer diseases, gastric outlet obstruction is usually caused by a combination of edema, spasm, fibrotic stenosis and gastric atony. We experienced a case of neonatal gastric ulcer with a large hematoma in a 3-day-old infant presenting with repeated vomiting, poor oral intake, and abdominal distension. For the differential diagnosis, we did abdominal ultrasonography. Hematoma was diagnosed by abdominal ultrasonography. Endoscopic examination confirmed the hematoma and the presence of gastric ulcerations. We report this case with a brief review of the literature.

Is the Error-Coder Training Erroneous?

김준식 한국중앙영어영문학회 2013 영어영문학연구 Vol.55 No.3

Identifying and analyzing errors of language learners has been one of the major practices to serve the various purposes of such applied linguistics as language learning and teaching, language acquisition, and language testing. However, far too little attention has been paid to error-coder trainings, considering that error-coders’ consistent and accurate practice directly affect the reliability and validity of a study. This paper discusses the issues and decisions taken during a series of such error-coding trainings as introduction, workshop, feedback, and discussion. 96 written scripts extracted from the Yonsei English Learner Corpus (YELC) 2012 were used and four native speakers of English, who are currently teaching English at Yonsei University Foreign Language Institute, were hired as error-coders. A simplified version of the error tagging manual (Dagneaux et.al., 1996) was used to train the coders. For the error-coder calibration, agreement rates among coders were not only measured three times, but also a questionnaire survey and group interview were conducted. In this talk, This study reports a) what problems do the error-coders encounter in identifying errors and assigning codes corresponding to errors; b) why do the coders think they are problematic; and c) how do we deal with problems.

G발표장 : 유동층2 ; G-44 : Characteristics of Multiphase Flow Catalytic Reactors for Modified Fischer-Tropsch Synthesis

김준식,이상봉,최명재,강용 한국화학공학회 2007 화학공학의이론과응용 Vol.10 No.1

To control and reduce CO2 emission, various countermeasures such as capture, storage and utilization have been proposed. One of the advanced concepts to mitigate CO2 is the catalytic conversion of CO2 into valuable chemical feedstock, called MFT (Modified Fischer-Tropsch), as it can be developed to commercial process by treating the large amount of CO2 rapidly. Recently, Fischer-Tropsch synthesis in the advanced multiphase flow reactors has been extensively investigated because of its numerous advantages such as effective heat removal generated from the exothermic reaction and high productivity. In this study, multiphase flow catalytic reactors such as fixed, fluidized and three-phase slurry reactor were employed to the MFT reaction. It has been found that performance of fluidized bed and slurry reactor is superior to the fixed bed reactor from the viewpoint of hydrocarbon productivity and light olefins or heavy waxes selectivity, respectively. Also, the effects of operating variables on the CO2 conversion and its product distribution in these catalytic reactors will be presented.

김준식,김지영,이동철,곽현정 대한마취통증의학회 2010 Anesthesia and pain medicine Vol.5 No.1

Background: The purpose of this study was to determine the clinical effective dose of alfentanil required for successful tracheal intubation during inhalation induction using 5% sevoflurane without neuromuscular blockade in children sedated with ketamine. Methods: Twenty-one children, aged 3−10 years, undergoing surgeries under general anesthesia were enrolled into the study. All patients were premedicated with 0.004 mg/kg glycopyrrolate intramuscularly 30 min before anesthesia. To facilitate separation of the child from the parents, intravenous 1 mg/kg ketamine was given prior to transfer into the operating room. After inhalation induction with 5% sevoflurane and 100% oxygen, pre-determined dose of alfentanil was injected over 20 sec. The dose of alfentanil was determined by modified Dixon's up-and-down method (2μg/kg as a step size starting from 12μg/kg). The study ended when six independent pairs of patients, who manifested cross over from ‘failure’ to ‘success’ for tracheal intubation, were recruited. Results: In 50% of children, the effective bolus dose (ED50) (95%confidence intervals) of alfentanil for successful tracheal intubation was 7.2μg/kg (6.3−8.1μg/kg) during sevoflurane inhalation induction. From isotonic regression, 95% effective dose (ED95)(95% confidence intervals) of alfentanil was 9.9μg/kg (2.2−16.0μg/kg). Conclusions: During inhalation induction using 5% sevoflurane without neuromuscular blockade after ketamine sedation, the ED50and ED95 of alfentanil for successful tracheal intubation were 7.2μg/kg and 9.9μg/kg in children, respectively.

B-Type Natriuretic Peptide Assay for the Diagnosis and Prognosis of Patent Ductus Arteriosus in Preterm Infants

김준식,심은정 대한심장학회 2012 Korean Circulation Journal Vol.42 No.3

Background and Objectives: Patent ductus arteriosus (PDA) is a significant cause of morbidity and mortality in preterm infants. Measurement of plasma B-type natriuretic peptide (BNP) has been reported to be a useful bedside screening tool for the presence of hemodynamically significant PDA (hsPDA) in neonates. This study was conducted to investigate the usefulness of a BNP assay as a biochemical marker for the diagnosis of hsPDA and predictive biomarker of the response to indomethacin in preterm infants. Subjects and Methods: Preterm infants born at <37 weeks’ gestational age were prospectively enrolled within 24 hours of birth. Plasma BNP levels were measured on days 1, 4, and 7. Significant PDA was diagnosed by large ductal flow with left to right shunt on color Doppler echocardiography, along with clinical features of PDA. Following that, hsPDA was treated with indomethacin. Results: A total of 28 preterm infants were prospectively enrolled in this study. Seven infants with PDA had higher on day 4 plasma BNP values (median 654.68 pg/mL; range 428.29-1280.00) compared to the control group (median 124.52 pg/mL; range 37.21-290.49). The area under the receiver operator characteristic curve for the detection of hsPDA was high: 0.998 (95% confidence interval: 0.995-1.002). The cutoff of BNP concentration for the diagnosis of hsPDA was determined to be 412 pg/mL (sensitivity: 100%; specificity: 95%). Conclusion: B-type natriuretic peptide can be a useful biomarker for the screening and diagnosis of PDA in preterm infants. Serial BNP measurements are valuable for assessing the clinical course and indomethacin responsiveness of PDA.

Although augmentation rhinoplasty with silicone implant was once the mainstream technique, more complex rhinoplasty procedures that focus on reshaping the nasal tip and columella are required to meet the customers' demands. After columellar control strut or septal extension graft have been introduced for the correction of the nasal tip and columella, the results of augmentation rhinoplasties were very good. But, the problem is the dimension of the septal cartilage which is used for the graft material. So, we dissected a total of 10 cadavers. The anterior- posterior dimension and the cephalic-caudal dimension of the septal cartilage were measured as if it were a rectangular shape. With using a 10mm L-shaped strut, a septal cartilage was measured, too. As the results, we found that the anterior-posterior dimension of the septal cartilage was 22.1mm on average, and the cephalic-caudal dimension was 28.0mm on average. The average size of the septal cartilage was 627.2mm2. With using a 10mm L-shaped strut, the possible size of the graft was 226.2mm2 with an average anterior-posterior dimension of 12.1mm and an average cephalic-caudal dimension of 18.0mm. This report will be beneficial when the surgeon performs the various rhinoplasty techniques using the septal cartilage.

김준식,권재현,차득기 한국국토정보공사 2008 지적과 국토정보 Vol.38 No.1

The purpose of this study is to verify the quality of RTK surveying results by NMEA data obtained by RTK-GPS and to develop a method in order to enhance the reliability of cadastral surveying so that it could be applied to field surveying. For this, the module which can verify the quality of RTK-GPS surveying results in the field was developed. In the testing module, $GPLLQ data suppling location information can be identified during surveying operation through the PDA screen and RTK-GPS data could be received with the permitting the accuracy and the number already set, calculating standard declination and storing average measurements as decisive coordinates. In order to evaluate the efficiency of the verification module, the results of pilot surveying by TS surveying were compared and analysed. As a result, it is illustrated that the quality verification module of RTK-GPS surveying results could be applied to cadastral surveying very usefully. 본 연구에서는 RTK-GPS측량의 NMEA데이터를 이용하여 RTK측량성과의 품질을 검증하고 지적측량의 신뢰성을 확보하기위한 기법을 개발하여 실무에 적용시키는 것이 연구의 목적이다. 이를 위해 PDA를 사용하여 RTK-GPS측량성과의 품질을 현장에서 검증할 수 있는 모듈을 개발하였다. 검증 모듈은 지역위치와 정확도 정보를 제공하는 Leica GPS의 고유 포맷인 $GPLLQ데이터 정보를 현장 측량수행 중 PDA화면에서 확인할 수 있고, 설정된 정확도이내의 데이터를 연속적으로 설정된 개수만큼 수신하여 표준편차를 산출하고 계산에 사용된 좌표의 평균값을 결정좌표로 저장한다. 검증모듈의 효율성을 평가하기 위해 토탈스테이션(TS:Total Station)측량 등을 이용하여 실험측량을 수행하고 결과를 비교분석하였다. 실험결과 RTK-GPS 측량성과 품질 검증 모듈은 지적측량의 실무에 유용하게 적용할 수 있을 것으로 판단되었다.
