Afferent loop syndrome is an uncommon complication of a gastrectomy and Billroth Ⅱ reconstruction. It may cause symtoms at any time from the first postoperative day to many years after the gastrectomy. Afferent loop syndrome is characterized by abdominal pain, vomiting and elevation of serum amylase. Thus, it is difficult to differentiate afferent loop syndrome from other cause of acute pancreatitis. However, the history of gastrectomy can be an important clue for diagnosing afferent loop syndrome. We experienced one case of chronic afferent loop syndrome with acute pancreatitis. After appropriate management, the abdominal pain disappeared and serum amylase level decreased. We report this case with a review of relevant literatures.

유성란,정기철,상병찬,이준헌 충남대학교 농업과학연구소 2004 농업과학연구 Vol.31 No.2

Myostatin is a transforming growth and differentiation factor-β family member that acts as a negative regulator of muscle growth. Previously, mutations in the myostatin gene were known to be related to double muscling phenotypes in cattle. Because myostatin gene is highly related to muscle mass, also meat quality, in cattle, we sequenced whole myostatin mRNA and investigated the SNPs (Single Nucleotide Polymorphisms) in Korean cattle (Hanwoo). The results indicated that Hanwoo had an SNP in nt2385 and this mutation can be a useful marker with further verifications. We also investigated expression patterns of the myostatin gene from various muscle tissues and organs. Northern blotting results indicated that myostatin expression was restricted in muscles with variable expression levels. The results presented here can be used as a valuable information for meat quality related traits and muscle mass in cattle.

李鳳容,李基協,金正勳 弘益大學校 1983 弘大論叢 Vol.15 No.2

In applying linear programming to the production cost for generation planning, the probabilistic features of random loads and random generations cannnot normally be treated. So, in the conventional methods, some simplifications or ommittances are usually made. This paper proposes a new and effieient approach to the "probabilistic" production cost by the stadard linear programming package. The random loads and the random generations are discretized so that the production costs can be in linear form with linear constraints, and the convolution of load and generation is performed. The convolution itself is also a very time-consuming process, but an efficient method is suggeted in the paper. The proposal method is tested in a real scale power system and the various results are compared. From this demonstrations, it is concluded that the proposed method is a powerful tool for the probabilistic production costing and it is expected that the proposed method can further be extended for the generation planning.

연구 배경 : 적정한 약물요법을 순발력 있게 시행하기 위해서는 CPS 업무가 신속, 정확하게 수행되는 것이 필수적임에도 불구하고 지금까지 CPS 업무의 신속성, 정확성을 향상시키기 위한 객관적인 업무 표준은 물론 그의 측정까지도 전무한 실정이었다. 이에 수요자인 의사의 측면에서, CPS 자문결과의 신임도에 영향을 미치는 업무의 순발력과 정확성을 향상시키기 위해 CPS 업무의 신속성, 정확성에 영향을 미치는 요인을 파악, 분석하고 이를 향상시킬 수 있는 업무 표준을 개발하는 것을 목표로 6-Sigma 기법을 사용하여 본 연구를 진행하였다. 방 법 : CPS 업무의 신속성 평가를 위해 전체 업무 과정과 부분별 업무 과정에 대한 소요 시간을 측정하였고, 정확한 평가를 위해 예측되는 Cpeak와 실제 측정된 Cpeak를 비교하였다. CPS 업무에 대해 6-Sigma 기법을 사용하여 개선이 필요한 사항을 파악하고 이에 대한 개선활동을 한 후, 개선 활동 전과 후의 CPS 업무의 신속성과 정확성의 σ 수준을 각각 측정하여 이의 향상 정도를 잠재적인 경제적 이익으로 환산하였다. 결 과 : 신속성은 제 1차 자료수집 기간(대조군, 현황 파악 기간) 중 총 소요시간은 평균 930.6±583.2이었으며, 채혈-검체 접수 : 140.4±8705분, 검체접수-약물농도 결과보고: 48.4±23.1분, 결과보고-CPS 보고서 작성 : 741.8±510.6분으로 측정되었다. σ 수준은 총 소요시간의 경우는 0.56σ, 단계별로는 각각 0.45σ, 5.70σ, 0.30σ이었다. 제 2차 자료수집 기간(개선군, 개선활동 평가 기간) 중 총 소요시간은 평균 659.1±344.1분이었고 단계별로는 각각 92±66.2분, 48±28.0분, 518.9±340.7분이 소요되었다. σ 수준은 총 소요시간은 1.75σ이고, 단계별로는 1.32σ, 4.70 σ, 1.10σ로서 총 소요시간과 단계별 소요시간이 1차 자료수집기간에 비해 향상되었다. 정확성 측면에서는, 대조군의 경우, 예측 Cpeak와 실측 Cpeak의 차이는 평균은 0%, 분산 ±27.10%, σ 수준은 -0.56σ이었고 개선군의 평균과 분산 그리고 σ 수준은 각각 0%, ±15.10%, 0.14σ로 향상되었다. CPS 신속성, 정확성 향상으로 인한 경제적 이익은 정확성 측면에서 380만원/년, 신속성 측면에서 1350만원/년으로 총 1730만원/년의 비용절감 효과가 있었다. 결 론 : CPS 업무 흐름에 따라 CPS 효율성에 영향을 미치는 요인을 분석한 결과 CPS 효율성 향상을 위해서는 투약관련 의무 기록의 정확성, 임상병리 검사의 정도관리 향상, 그리고 관련 부서와의 원활한 업무 협조가 가장 중요하였다. The effectiveness of CPS (Clinical Pharmacokinetics Service), one of pharmacist's clinical services, was emphasized by many studies since 1985 it was introduced Korea about. But in the view of clinicians (medical doctors), customers, it's convenience or reliability was not properly evaluated for applying it to patient's care. To improve quality of Clinical Pharmacokinetics Service (CPS), the speed and the accuracy of CPS, the key points of efficiency in CPS, were evaluated by using 6-Sigma method. The speed of CPS was evaluated using total hours it took from blood sampling by a nurse to sending a CPS report to the patient's chart by a clinical pharmacist. Total hours were divided into blood sampling-to-sampling registering, sampling registering-to-C_(peak) result reporting, and C_(peak) result reporting-to-pharmacist's CPS report. The accuracy of CPS was evaluated by the difference between expected C_(peak) and measured C_(peak). Then the speed and the accuracy of CPS were expressed as σ level. After the campaign for improvement by Six Sigma method, the speed was improved by 1.19σ (before and after the campaign; 0.56σand 1.75σ, respectively) and the accuracy was improved by 0.7σ (before and after the campaign, -0.56σand 0.14σ, respectively). Exact recordings of dosing time, drug infusion hours and blood sampling time were shown to have profound effect on the accuracy of CPS. The improvement in the speed and the accuracy of CPS could produce potential financial benefit of U.S.$ 15,300 a year. There have not been studies on evaluating and objectifying as numerical value for the speed and the accuracy of CPS; thus, 6-Sigma method for improving efficiency in manufacturing process was applied to CPS process by expressing as σlevel. The speed and the accuracy of CPS could be improved by tightly controlling many factors related to CPS efficiency.

TFD는 기능이 알려진 짧은 DNA sequence(signal)들과 그와 연관된 저널 자료로 구성된 데이타베이스이다. 임의의 DNA에서 이 데이타베이스의 sequence들을 검색하여 signal을 찾는 프로그램으로 Dan S. Prestridge가 개발한 SIGNAL SCAN이라는 프로그램이 사용되고 있는데, 이는 간단한 문자열 비교 알고리즘을 사용한다. 본 연구에서는 계산상 보다 효율적인 검색을 위해서, TFD의 sequence를 검색하기 위한 automata를 구성하는 프로그램과, 이 automata에 따라 signal을 검색하도록 하는 TFSCAN이라는 프로그램을 개발하였다. 검색된 signal에 대한 관련 문헌의 검색에서도 인덱싱 방법을 이용하여 계산 속도를 향상시켰다. 프로그램의 사용을 단순화시켰고, 결과 내용을 signal과 관련된 모든 정보를 일목요연하게 보여줄 수 있도록 구성하였다. 이 프로그램을 Web을 통해서도 사용할 수 있도록, GINet Web 서버에 TFSCAN 입력용 form과 CGI 프로그램을 개발·설치하였다. 본 연구의 특정 Motif 패턴으로 구성된 데이타베이스 검색에서, automata를 응용한 알고리즘을 이용하여 계산상 급격히 향상된 결과를 얻을 수 있음을 알 수 있었는데, 이는 생물학의 여러 패턴 검색에 응용될 수 있을 것이다. 더욱 민감한(sensitive) signal 검색을 위해서, 이와 같이 automata를 활용하고, 이 automata를 최적화하는 알고리즘 연구를 계속하고 있다. TFD is a transcription factor database which consists of short functional DNA sequences called as signals and their references. SIGNAL SCAN, developed by Dan S. Prestridge, is used to determine what signals of TFD may exist in a DNA sequence. This program searches TFD database by using a simple algorithm for character string comparison. We developed TFSCAN that aims at searching for signals in an input DNA sequence more efficently than SIGNAL SCAN. Our algorithms consist of two parts, one constructs an automata by scanning sequences of TFD, the other searches for signals through this automata. Searching for signal-related references is radically improved in time by using an indexing method. Usage of TFSCAN is very simple and its output is obvious. We developed and installed a TFSCAN input form and a CGI program in GINet Web server, to use TFSCAN. The algorithm applying automata showed drastical results in improvement of computing time. This approach may apply to recognizing several biological patterns. We have been developing our algorithm to optimize the automata and to search more sensitively for signals.

河海求,崔斗石,金基延 최신의학사 1973 最新醫學 Vol.16 No.7

Aortography with selective visceral injections has been recognized as highly diagnostic and easy technique for the evaluation of various abdominal mass lesions. At department of Radiology, National Medical Center, Seoul, Korea seventy-two (72) patients whose chief complaints were slowly growing abdominal mass were studied with angiography after conventional examinations (barium study, I. V. P. etc) for last several years(1965-1972). The angiographic patterns were comprehensively analized. Almost cases (about 64 cases) were retroperitoneal expanding lesions which were not well detected with conventional radiological study (barium study, I. V. P. etc). The all expanding lesions were composed of renal expanding lesions(42 cases), other retroperitoneal expanding lesions (17cases), and liver, spleen, pancreatic lesions (13 cases). The angiography with selective visceral injections was the most diagnostic and easy technique without any permament complication than any other conventional studies.

This study was carried out to investigate the style of livestock house, concentration of malodorous substances of livestock feces and livestock houses in Daejeon area. Among the livestock houses investigated, as most of cow pens(94.5%) have sawdust or chaff on the bottom, there was no leakage of feces out of pen. Most pig pens adopted slury style, but some of them currently use buffering material on the bottom. It is thought that there will be no possible contamination leakage. When it comes to hen house, all the broiler house use litters on the bottom and all the layer house use scrapper. It is also thought that there will be no possible contamination leakage. 3 out of 12 deer pens used buffering material on the bottom, 10 places were maintained in a traditional method, and 7 places left possibility of contamination leakage considering whether the roof was installed or not. The contents of ammonia, amine and volatile fatty acid in fresh feces were lower compared to rotten feces, but the concentration of sulfur-containing matter - hydrogen sulfide, methylmercapthan and ethylmercapthan were higher compared to rotten feces. In the case of malodorous ingredient in livestock houses, only small amount of ammonia and hydrogen sulfide were detected in pig pen and hen house, and other ingredients were not detectable. And those who are engaged in animal husbandry reacted negatively to the use of feed additives for decreasing malodor. In conclusion, it is not worrisome that contamination can be leaked out of animal raising facilities. But if we take into consideration that the point of investigation time is wintry season, there should be more considerate attitude. And feed additives for decreasing malodor need establishing criteria in the manufacturing process.
