급성 일산화탄소중독환자의 예후를 예측하는 기초자료를 얻고자 1985년 10월부터 1989년 4월까지 급성 일산화탄소중독으로 영남대학병원 응급실을 통해 COHb검사로 확진되어 입원치료한 116명의 환자를 대상으로 임상소견 및 검사 소견을 비교, 분석하고 이들 소견과 지연성 후유증과의 관련성을 조사하여 다음과 같은 성적을 얻었다. 1. 입원환자 116례의 내원시 의식상태는 기면상태의 군이 36.2%로 가장 많았으며, 남녀의 비는 1:1.5로 여자가 많았다. 2. 내원시 의식장애가 심할수로 동맥혈의 pH 및 PaCO₂는 감소하는 경향을 보였는데, 이는 대사성산증에 대한 소견으로 보인다. 3. 일산화탄소중독으로 인한 초기 검사소견중 백혈구증다증은 65.5%, 헤마토크리트의 상승 은 23.3%, 고혈당은 19.8%, GPT의 상승은 19.8%, creatinine의 상승은 0.9%, 뇨당검출은 12.1%였다. 4. 심전도 검사에서는 35.5%에서 이상소견을 보였는데 25.0%가 rhythm의 변화를, 15.5%가 ST, T절의 이상과 함께 나타났으나 전도장애의 이상은 없었다. 5. 뇌파검사에서는 경도이상의 이상소견을 보인 환자가 93.1%였으며, 이중 중등도의 이상소견을 보인 환자가 80.2%로 가장 많았다. 6. 입원환자중 지연성 후유증의 발생빈도는 7.8%였으며, 이들은 노출시간이 길고(>8시간),백혈구증다증(>20,000) 및 뇌파이상(>중등도)이 심하였다. To obtain the basic data of prognosis of acute carbon monoxide(CO) intoxication, one hundred and sixteen cases of CO intoxication defined by carboxyhemoglobin(COHb) and admitted via emergency room of Yeung-nam University Hospital from Oct. '85 to April' 89 have been clinically analyzed and evaluated, including delayed postanoxic encephalopathy(DPE) and the following results were obtained. 1. The ratio of male to female was 1 : 1.5 and mental state was drowsy mostly(26.2% of 116 cases) 2. The more disturbed the mental state, the more decreased was the arterial pH and PaCO₂, which may be the result of metabolic acidosis. 3. The early laboratory findings in patients of CO intoxication were as follows : leukocytosis-65.5%, increase of hematocrit-23.3%. hyperglycemia-19.8%, increase of GPT-19.8% increase of creatinine-0.9% , and glucosuria-12.1%. 4. The early findings of EKG were abnormal in 35.3% : change of rhythm-25.0%, abnormal ST segment-15.5% (change of rhythm and abonormal ST segment-5.2%) but the conduction disorder was not present. 5. The abnormal EEG above mild degree was 93.1%, of which moderate was most frequent(80.2%). 6. The incidence of DPE was 7.8% among all admitted CO patients. DPE cases had long duration of exposure time(8 hours), severe leukocytosis(20,000) and an abnormal EEG(MA).

To establish the way of processing of Gae-Woo jeot which used abalone intestine that has not been systematically used compare to its characteristic taste and fame as main ingredient and to develop as a local tourist good, the change of constituents the quality of salted fish products suring Gae-Woo jeot fermentation were examined. The results are as follows. 1. In the organoleptic test, Gae-Woo jeot which fermented through 65 days were dominant and the group of 105 salkt concentration were better than that of 20%. It was the best of 10% salted products to add small abalone. Both law salted(10%) and high salted (20%) Gae-Woo jeot were similar in general constityents, nutrients and texture. 2. Compositions of highly unsaturated acid were farely high to 45.6% and 46.1% in small abalone added froup and top sheel added group respectively. during 3 months fermentation low decreasing rate of 3~4% was shown. EPA(eicosapentaenoic acid) was approximately 7~8% and DHA(docosahexaenoic acid) was extremely low to be less than 0.3%. 3. In the changes General composition and pH, pH was within range of 4~5.5, 9~12% in protein, 3~5% in total sugar, 0.5~1% in lipid and approximately 1% in ash. 4. Gae-Woo jeot can be made with 10% low salting method, and 10% group gets all the better for taste, small abalone adding is recommended. 5. When low salt fermented fish of 10% is processed, it is highly recommended to put sorbitol, ethyl alcohol, lactic acid or other humectant for better taste and longer storage and good quality food additives must be developed for tourist and presently applied mil ordering transportation must be sought.

朴榮浩,姜泳周 釜山水産大學校 1974 釜山水産大學 硏究報告 Vol.14 No.1

冷凍명태 fillet의 冷凍變性 防止에 미치는 各種 添加物處理의 效果를 試驗코져 fillet를 凍結前에 21種類의 處理液에 5分間 浸漬하여 凍結貯藏한 후 解凍하였 을때의 free drip, expressible drip의 發生量 및 drip中의 total solid, nitrogen, DNA의 含量을 定量하여 冷凍變性의 程度를 比較檢討하였다. 1. Free drip는 處理液의 種類 및 濃度에 따라 큰 差를 나타내었으나, expressible drip에 있어서는 그 差가 적었다. 2. Drip량의 減少에 있어 效果가 큰 處理液은 sodium polyphosphate 10%, sodium polyphosphate: sodium pyrophosphate(1:1) 10% 및 5%, sodium chloride 10%, sodium citrate 10%였다. Sodium metaphosphate, glucose, sucrose 및 sorbitol의 處理 效果는 그다지 크지 못하였고, malic acid 處理는 큰 逆效果를 나타내었다. 3. Drip中의 total solid 및 nitrogen은 大체的으로 drip量에 比例하는 結果를 보였으나, malic acid 處理區의 nitrogen量은 drip의 發生量에 비하여 相當히 적은 量을 나타내었다. 4. Drip中의 DNA量에 미치는 前處理의 效果는 drip發生量 및 drip中의 total solid, nitrogen의 경우 보다 현저하였고, 特히 重合燐酸鹽의 效果는 커서 sodium metaphosphate까지도 良好한 結果를 나타내었다. Malic acid 處理區는 drip量은 월등히 많은데도 DNA 含量은 微量에 지나지 않았다. The present study was conducted to evaluate the effect of prefreezing treatment, dipping the fillets into such solutions as condesed phosphate, sugars, and sodium chloride, upon the freezing denaturation of Alaska pollack muscle. The degree of freezing denaturation was estimated by measuring the amount of drip released, contents of total solid, total nitrogen, and DNA in the drip. Fillets were frozen at -27℃- -28℃ and stored for 20 and 40 days at -18℃- -20℃ . The amount of free drip was greatly dependent on treating solution although the expressible drip was not so much variable. Among the treating solutions examined, 10% sodium polyphosphate, 5% and 10% of the mixture of sodium polyphosphate and sodium pyrophosphate (1:1 w/w), 10% sodium chloride, and 10% sodium citrate appeared most effective ones to retard the releasing of drip. The effect of sodium metaphosphate, glucose, sucrose, and sorbitol was not so benefitable. On the contrary, malic acid showed a remarkable reverse effect. As a tendency, total solid, total nitrogen, and DNA in the drip varied proportionally to the amount of drip released. Releasing of DNA, however, was greatly affected by treating solutions comparing with that of total solid and total nitrogen. It was not the case in malic acid treated fillet particularly in DNA content, even though the amount of drip was greater than other cases, DNA content was far less.

金成洙,河璡桓,姜永周,金洙賢,金永東,宋大鎭 제주대학교 1990 논문집 Vol.30 No.-

To evaluate the composition of Gae-Woo Jeot which is one of important traditional salted and fermented sea foods in Cheju Do, changes of nucleotides and their related compounds, free amino acids, TMAO(trimethylamine oxide), TMA(trimethylamine) contents and histological properties during fermentation was examined. AMP was as high as 3.6?mole/?? in raw small abalone but IMP content was only trace while hypoxanthine and IMP was dominant in raw topshell-4.5 mole/?? and 4.3??mole/?? respectively. Hypoxanthine was predominant in 65 days fermented Gae-Woo Jeot. Main amino acid in Gae-Woo Jeot were glycine, arginine, glutamic acid, alanine, valine and histidine in order. These were consisted 50~60% of the total free amino acid while phenylalanine, tyrosine, methionine and isoleucine were poor in content. During fermentation TMAO decreased slowly and eventually disappeard within 85 days while TMA was increased until 65 days and started to decrease down to 6~9mg%. Muscle texture showed the disappearance of elasticity soon after the adding of 10% salt while no change of texture was oberved until 50 days of fermentation in 20% salt group.

배관의 축방향 균열에 대한 균열진전 특성에 관한 연구

진영준 忠州大學校 2007 한국교통대학교 논문집 Vol.42 No.-

It is well known that pipelines have the highest capacity and are the safest and least environmentally disruptive form of transporting oil and gas. However, pipeline damage caused by both internal and external corrosion is a major concern threatening the reliability of oil and gas transportation and the soundness of the pipeline structure. In this study, we estimate the allowable damage by comparing the ASTM B31G code to a modified theory considering diverse detailed corrosive forms. The ASTM B31G code has been developed as the evaluation method for reliability and incident prevention of damaged pipelines based on the amount of loss due to corrosion and the yield strength of materials. Furthermore, we suggest a method for estimating the expected life span of used pipelines by utilizing the reliability method based on major variables such as the depth and length of damage and the corrosion rate affecting the life expectancy of the pipelines.

김영찬 安東大學校 工業技術硏究所 1999 공업기술연구논문집 Vol.6 No.1

분무냉각은 주로 강재의 열처리과정에 많이 이용되고 있다. 그러나 TMCP에 의한 강재냉각시 냉각영역의 출구에 있어서 강재의 온도가 불균일하게 되는 냉각불안정현상이 큰 문제점으로 남아 있다. 이러한 문제점의 해결에는 우선 강판의 열처리과정에 있어서 분무냉각 열전달특성에 대한 명확한 이해와 그 평가법의 개발이 중요하다고 할 수 있다. 본 연구에서는 주로 냉각액체의 포화온도이상의 물체를 냉각시키는 경우에 있어서의 분무냉각 열전달특성에 대해 최근의 연구결과들을 중심으로 고찰하기로 한다. Spray Cooling has been used as a technique for heat treatment of metals in the metallurgical industry. However, since there are many factors affecting spray cooling heat transfer and the effects of these factors are very complicated, it is still a difficult task to predict spray cooling heat transfer of actual system. Understanding the effect of these factors has become very important because of the advent of the so-called Thermo-Mechanical Control(TMC) process in the steel industry and other new applications. The aim of TMC process is on-line control of the metallurgical structure of steel. This paper presents an overview of the spray cooling heat transfer and the results of recent study on spray cooling.

이영민,이창수 위덕대학교 산업기술연구소 2003 산업기술연구소 논문집 Vol.7 No.1

안동댐 상류유역의 갈수우량 특성에 대해 분석하기 위해 지역빈도해석기법을 이용하여 L-moment 기법에 따라 빈도분석을 실시하였다. 그 결과 적합성 척도 |Z|≤1.64의 기준을 만족하는 최적분포형은 GLO(generalized logistic) 분포형으로 분석되었다. 본 연구에서 얻어진 모형은 낙동강유역에서의 수공구조물 설계시 이수안전도에 따른 기준 저수량 설정과 갈수시 댐 운영에 있어 저수유입량의 산정에 유용할 것으로 판단되며, 최근 새로이 개발되어지는 분포형에 대하여 지역빈도분석방법을 통한 지속적인 연구가 필요할 것으로 사료된다. Drought rainfall characteristics are analyzed through the drought frequency analysis with regional frequency analysis using L-moment method. The results are as follows : It is appeared that the optimal distribution model which satisfies the criterion of │Z│≤1.64 is GLO(generalized logistic) distribution. It is thought that the model obtained by this study is helpful to estimate standard storage according to practice of safety standards for the design of impounding facilities when hydraulic structure is designed, and storage inflow quantity when dam is operated in drought period. Continuous study through regional frequency analysis method for recently developed frequency model is needed.
