쌀국수의 유통 안전성 확보를 위한 기초자료를 확보하기 위하여 최근 각광받고 있는 저온 플라즈마 처리에 의한 쌀국수의 품질 특성 분석을 하였다. 본 연구에서 이용한 플라즈마는 컨테이너형 유전격벽 플라즈마로 방전 가스는 공기를 활용하여 0, 5, 10 및 20분 처리하였고 미생물 감균효과, 색도, 경도 및 지질산패도 변화를 측정하였다. 쌀국수에 B. cereus 및 E. coli O157:H7을 접종한 후 20분간 플라즈마 처리 시 E. coli O157:H7은 2.75 log CFU/g 감소하였고, B. cereus는 검출되지 않았다. 색도 측정결과 플라즈마 처리에 의해 명도(L<SUP>*</SUP>), 적색도(a<SUP>*</SUP>) 및 황색도(b<SUP>*</SUP>) 모두 증가하였으며, 경도는 처리시간이 증가함에 따라 감소하는 경향을 보였다. 하지만 플라즈마 처리에 의해 지질산화가 일어나는 경향을 보였다. 따라서 공기로 방전된 저온 플라즈마 기술은 쌀국수의 품질안전성을 개선될 것이라고 판단되나 관능적 품질 특성 개선을 위한 적합 플라즈마 모델 선정, 포장방법 개선 등의 후속연구가 필요하다고 판단된다. Cold plasma has been applied to improve quality of food product; however, studies on its effects on microbial and physicochemical qualities of rice noodles are rarely conducted. In this study, changes in the quality characteristics of rice noodles treated by cold plasma were determined. Cold plasma was generated in a square-shaped plastic container (250 W, 15 kHz, ambient air), and dielectric barrier discharge plasma treatments were applied to rice noodle samples for 0, 10, or 20 min. Rice noodles inoculated with either Bacillus cereus or Escherichia coli O157:H7 were subjected to plasma treatment for 20 min, and the approximate bacterial count reduction were 4.10 and 2.75 log CFU/g, respectively. The Hunter color values of the sample were increased after cold plasma treatment. Peroxide values and thiobarbituric acid reactive substance (TBARS) were increased with an increase in cold plasma treatment time. Futhermore, lipid oxidation was enhanced. Although further studies are warranted to evaluate changes in chemical qualities, such as lipid oxidation of rice noodles, induced by cold plasma, the results suggest that cold plasma can improve the microbial and physical qualities of rice noodles.

한국인의 정체성과 의사소통전략

민향기 한국독일어교육학회 2003 외국어로서의 독일어 Vol.12 No.-

In diesem Aufsatz geht es um das Identit¨atsbewuβysein der Koreaner und seinen m¨oglichen Einfluβ auf ihre Kommunikationsstrategie bei der Anwendung des Deutschen mit deutschsprachigen Muttersprachlern. Aus der Erfahrung weiβ man schon, dass koreanische Deutschlerner und Studenten in Deutschland l¨agere Zeit ben¨otigen, bis sie Deutsch relativ gut beherrschen. In dieser Arbeit ist davon ausgegangen, daβ die Art und Weise, wie die koreanischen Lerner mit ihrer Identita¨t umgehen, und die daraus resultierenden Kommunikationsstrategien wesentliche Rolle spielen. Um diese Annahme zu ¨uberpr¨ufen, wurde 08. 2002-02. 2003 eine Umfrage bei vier Gruppen - Sch¨uler, Studenten in Korea und koreanische Studenten in Deutschland und Deutschlehrer an koreanischen Oberschulen Studenten in Deutschland und Deutschlehrer an koreanischen Oberschulen - durchgef¨uhrt. Nach der Datenerhebung sind zwei Resultate herauszustellen: das eine ist, dass viele koreanische Deutschlerner passiv und tolerant reagieren, obgleich es sich um die Bedrohung ihrer Identit¨at handelt, und das andere, dass sie sehr aktiv reagieren w¨urden, wenn sie bei der Kommunikation mit Deutschsprachigen Probleme oder Hindernisse zum Verst¨andnis h¨atten. Die zwei Ergebnisse sind m. E. einander widerspr¨uchlich. Die Ursache des Widerspruchs zwischen den beiden Antworten ist noch zu erforschen.

Although many drug are thought capable of initiating acute pancreatitis, following azathioprine administration represents the 5% incidence by far the highest recorded incidence to date. We report a 35-year-old male who developed acute pancreatitis in the course of treatment with azathioprine for Behcet's disease. He was admitted due to abdominal pain, diarrhea, and fever for 10 days. Serum amylase and lipase levels were 510U/L and 3702U/L respectively. The abdominal CT scan revealed diffuse enlargement of the pancreas. There was no history of alcohol use or gall bladder disease. We considered drugs, especially azathioprine, as the cause of acute pancreatitis. We diagnosed it as acute pancreatitis. The patient was treated conservatively with hydration and analgesics. The symptom subsided within four days. Five days later, azathioprine was resumed. And the patient complained of abdominal pain. The elevated levels of serum amylase and lipase confirmed the recurrence of pancreatitis. His symptom subsided when azathioprine intake the stopped, and the serum amylase and lipase levels returned to normal level within five days.

Tumor necrosis factor-related apoptosis -inducing ligand (TRAIL) is a recently identified member of the tumor necrosis factor cytokine superfamily. TRAIL has been shown to induce apoptosis in a number of tumor cells whereas cells from most of normal tissues are highly resistant to TRAIL-induced apoptosis. These observations have raised considerable interest in the use of TRAIL in tumor therapy. In this study we report the biodistribution fates and serum expression pattern of plasmid DNA encoding TRAIL (pTRAIL) delivered in erythrocyte ghosts(EG). pTRAIL was loaded into EG by electroporation in a hypotonic medium. The mRNA expression of pTRAIL was prolonged following delivery in EG-encap-sulated forms. EG containing pTRAIL showed significant levels of mRNA expression in the blood over 9 days. The organ expression patterns of pTRAIL delivered via EG, however, did not significantly differ from those of naked pTRAIL, indicating that the expression-enhancing effect of EG containing pTRAIL, was localized to the blood. These results suggest that pTRAIL-loaded EG might be of potential use in the treatment of hematological diseases such as TRAIL-sensitive leukemia.

조향정,민부기,문형배 圓光大學校 醫科學硏究所 2002 圓光醫科學 Vol.17 No.1

저자들은 우측 난소의 성숙 낭성 기형종에서 발생한 원발성 유암종 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 본 예는 수술 후 상부 소화기 내시경검사, 대장 내시경 검사 및 복부와 골반에 대한 전산단층촬영을 시행하였으나 특이 소견은 없었고 현재 6개월정도 추적 관찰중이다. The most common malignant change in cystic teratoma is squamous cell carcinoma, followed by carcinoid tumor and adenocarcinoma. Ovarian carcinoid tumor can be seen in the ovary as a metastasis of a tumor located in the gastrointestinal tract or elsewhere, as a component of adult cystic teratoma, or as a primary pure neoplasm of the ovary. The prognosis in primary carcinoid tumors (whether pure or as a component of cystic teratoma) is very good, whereas metastatic carcinoids have a poor outcome. We report a case of a primary carcinoid tumor arising in a mature cystic teratoma of the ovary that developed in a 38-year-old woman with a brief review of literature.

새로운 carbonyl 화합물의 합성에 대한 연구 : α,β불포화 산 amide의 새로운 Hofmann 반응 A Novel Hofmann Reaction of Unsaturated Amide

박민수,최원형 慶星大學校 1989 論文集 Vol.10 No.2

In connection with the applicability of Hofmann reaction to organic synthesis, by using N-halosuccinimide as halogen source, a novel procedure for Hofmann reaction of a,b-unsaturated carboxamide which is carried out unsuccessfully in usual Hofmann reaction condition, was developed. The Hofmann reaction product of a,b-unsaturated amide can be converted to corresponding carbonyl compound easily by hydrolysis. So, this procedure is thought to be very effective and practical method for preparation of carbonyl group.

The evaluation of menopausal status is an important subject in the field of treatment of hormone receptor positive breast cancer. According to the menopausal status, endocrine therapy should be categorized by individual patient. However, the gonadal injury caused by various therapeutic drugs and its recovery would confuse the interpretation of clinical and biological markers for ovarian reserve. There are some methods to examine the functional ovarian reserve indirectly. Ultrasonography for counting follicles is a relatively reliable procedure, although it is not feasible because of time-labor consumption and high cost. Biological marker from blood samples such as serum follicle stimulating hormone (FSH), serum estradiol (E2), serum inhibin, or anti-Müllerian hormone (AMH) would be a better choice. The examination of serum FSH and E2 is already recommended as biomarkers for measuring functional ovarian reserve in many guidelines. However, there are limitation of serum FSH and E2 in patients with chemotherapy- induced amenorrhea and treated by tamoxifen. AMH is promising biomarker in the field of infertility treatment even in the patients treated by chemotherapy. It might be a possible biomarker to determine the menopausal status for decision-making whether aromatase inhibitor could be applicable or not in hormone positive breast cancer patients with chemotherapy induced amenorrhea or treated by tamoxifen.

Production of valued materials from squid viscera by subcritical water hydrolysis.

Uddin, M Salim,Ahn, Hyang-Min,Kishimura, Hideki,Chun, Byung-Soo The Academy 2010 Journal of environmental biology Vol.31 No.5

<P>Subcritical water hydrolysis was carried out to produce valued materials from squid viscera, the waste product of fish processing industries. The reaction temperatures for hydrolysis of rawand deoiled squid viscera were maintained from 180 to 280 degrees C for5 min. The ratio of material to water forhydrolysis was 1:50. Most of the proteins from deoiled squid viscera were recovered at high temperature. The protein yield in raw squid viscera hydrolyzate decreased with the rise of temperature. The reducing sugar yield was higher at high temperature in subcritical water hydrolysis of both raw and deoiled squid viscera. The highest yield of amino acids in raw and deoiled squid viscera hydrolyzates were 233.25 +/- 3.25 and 533.78 +/- 4.13 mg g(-1) at 180 and 280 degrees C, respectively. Most amino acids attained highest yield at the reaction temperature range of 180-220 degrees C and 260-280 degrees C for raw and deoiled samples, respectively. The recovery of amino acids from deoiled squid viscera was about 1.5 times higher than that of raw squid viscera.</P>

The term “Mesiodens” refers to a supernumerary tooth that is present in the midline of the anterior maxilla. Supernumerary tooth results from aberrations in the initiation or proliferation period of dental developmental stage. The crown often has a conical shape, and its familial incidence has been reported in several instances. The author has observed 71 cases of supernumerary tooth occured at premaxilla between central incisors. Among the total tooth number of 86,70 were impacted, and 16 were erupted. In most cases(96.5%), supernumerary tooth located on the palatal side of adjacent teeth. Surgical and/or orthodontic treatment were performed in 53 cases, 21 cases, were left untreated for delayed surgical intervention.
