경상북도 영덕군의 하천에 서식하는 점몰개 spotted barbel gudgeon (Squalidus multimaculatus Hosoya et Jeon)의 근육에서 새인두흡충 Clinostomum complanatum (Rudolphi, 1814)의 피낭유충이 발견되었다. 감염된 점몰개는 "yellow grub"인 기생충의 피낭유충으로 인해 표면이 울퉁불퉁하게 보였으며, 수면위에 힘없이 유영하였고 일부 폐사한 개체도 발견되었다. 분리된 탈낭유충의 형태는 혓바닥 모양이었으며, 크기는 2.85~5.89 mm×0.8~1.99 mm였다. 어체당 1~98 개의 피낭유충을 분리하였으며 평균 감염수는 25개로 나타났다. 특히, 성어크기인 평균 7 cm 정도의 점몰개는 100% 감염되어 있었다. 본 연구는 한국의 자연수계에 서식하는 어류에서 C. complanatum 의해 질병이 발생하고 폐사가 일어난 첫 보고이다. The metacercariae of Clinostomum complanatum (Rudolphi, 1814) were isolated in the whole body muscle of wild freshwater fish, spotted barbel gudgeon (Squalidus multimaculatus Hosoya et Jeon) from the local river in Yeongdeok, Gyeongsangbuk-do, Korea. The infected fish with bumpy body surface by "yellow grub" showed erratic swimming behavior and some fish were died. The isolated excysted metacercariae were tongue shaped and 2.85~5.89 mm × 0.8~1.99 mm in size. 1~98 metacercariae were isolated in individual fish and mean infection intensity was 25. All examined adult spotted barbel gudgeon sizing 7 cm in body length were infected. This is the first report of disease outbreak and mortality caused by C. complanatum infection in wild freshwater fish in Korea.

This study analysed the mercury concentration in the hair of 62 students (male : 21, female : 41) of D university in Najusi, Jeon-Nam area. Also, questionnaire, which developed by NIES, were completed by the students. According to the questionnaire, most of the students had a higher intake of meat than that of fish. Also, among the students, there were many smokes and many had dental treatment with amalgam. Based on the gender, female showed 1.024 ${\mu}g/g$ and male showed 0.882 ${\mu}g/g$ of the mercury concentration. This means that female students had higher level of mercury in their hair, but it was not a significant statistic difference. Comparing by the intake frequency of meat, processed food stuffs, protein foods, it shows the more they at the higher mercury concentration was observed. According to the intake frequency of fish, when the number of times they intake increased, the mercury concentration was higher. Under one time was 0.857 ${\mu}g/g$ and twice or more times were 1.152 ${\mu}g/g$, which showed a significant statistical difference (p<0.05). Depending on the Life style, the mercury concentration in the hair was high with workout, outdoor activities, and direct smoking. The mercury concentration in the hair showed no difference for whether they received amalgam treatment but the personal dietary habit and the Living condition affects strongly on the mercury concentration level.

A 10 years old, intact male, Maltese dog with clinical signs of labored respiration, exercise intolerance and increasing of coughing was referred to the Veterinary Medical Teaching Hospital of Chungnam National University. Physical examination revealed tachycardia, panting and mild cyanosis. This case was diagnosed as mitral valve insufficiency by clinical signs, ascultation, blood chemistry, radiography and electrocardiography. This dog was treated with ACE inhibitor (enalapril), diuretics (furosemide) and bronchodilator (aminophylline) for 14 days. After treatment, clnical signs were disappeared and also this dog was needed to be continuous monitoring and sodium restricted diet.

김치 용매획분이 고 콜레스테롤 식이를 섭취한 토끼의 심장, 신장 및 폐의 항산화 효소계 활성에 미치는 영향

전혜년,김현주,송영옥 부산대학교 김치연구소 2003 김치의 과학과 기술 Vol.9 No.-

김치의 용매획분중 in vitro에서 LDL 산화억제 활성이 강했고 in vivo에서 지질저하 효과가 있었던 디클로로메탄 획분, 에틸아세테이트 획분, 수용성 획분이 고콜레스테롤 식이를 섭취한 토끼의 심장, 신장, 그리고 폐에서 항산화 효소의 활성에 미치는 영향을 살펴보았다. 과산화물 함량은 심장이 가장 높고 신장이 가장 낮았으나, catalase와 GSH-pxghkf성은 심장이 낮았고, 신장은 높은 활성을 나타냈다. Catalase, GSH-px 및 SOD의 활성은 모든 장기에서 1% 콜레스테롤 식이를 섭취한 대조군에 비해 김치 용매획분군에서 낮았고 특히 디클로로메탄 획분군의 항산화효소 활성은 유의적으로 낮았다(p<0.05). 이러한 결과는 김치 용매획분은 심장, 신장 그리고 폐에 지방축적을 억제하는 효과가 있었고, 그로 인해 지질 유리기의 생성이 적어, 각 장기에서 유리기를 제거하는 항산화 효소의 활성이 낮은 것으로 생각된다. The effects of dichloromethane (CH_(2)Cl_(2)), ethylacetate (EtOAc) or water (H_(2)O) fraction of Korean cabbage kimchi on anti-oxidative enzyme activities of the heart, kidney and lung of rabbit fed 1% cholesterol diet for 16 weeks were studied. The amount of kimchi fraction added to the 100g of diet was 8.3mg of CH_(2)Cl_(2), 5.6mg of EtOAc, and 221.9mg of H_(2)O, which are equivalent to 5% of freeze-dried kimchi in the diet. Each group had 6 rabbits and rabbit was housed individually. Lipid peroxide values for the heart was the highest followed by lung and kindey. But the activities of catalase and GSH-px were the lowest in the heart and the highest in the kidney. Activities of anti-oxidative enzymes (catalase. GSH-px, Mn-SOD, Cu, Zn-SOD) of rabbits fed kimchi solvent fractions added diets were lower than those of the control which fed 1% cholesterol diet. Among kimchi groups, CH_(2)Cl_(2) group showed the lowest(p<0.05) enzymes activities. Lipid accumulation in these organs fed diets with kimchi solvent fractions, especially with CH_(2)Cl_(2) fraction, were lower than that of the control. Therefore, production of the lipid free radicals might be suppressed and the activities of anti-oxidative enzymes responsible for removing the free radicals seemed to be lowered in kimch frachoin-fed rabbits.

전길자,최혜정,이준승 梨花女子大學校 韓國生活科學硏究院 1990 韓國生活科學硏究院 論叢 Vol.46 No.-

Protein carboxyl methyltransferase(EC 2.1.1.77) which has specificities for the protein containing abnormal aspartyl residues is investigated in lysosome, mitochondria, peroxisome in liver of fetus, pregnant rat and vacuole vesicles in beet root. The level of this enzyme in brain cytosol of normal rat was almost same as that in brain cytosol of pregnant rat. But in liver cytosol, PCM activity of fetal rat was increased 17-fold more than that of normal rat. Total enzyme activities in lysosome, mitochondria and peroxisome of fetal and pregnant rat were not changed. But the total methylatability of fetal rat were increased about 2-fold comparing to pregnant rat. Vacuole vesicles showed the enzyme activities and methylatabilities.

폴리에스테르 纖維에 대한 스티렌, 아크릴산 단량체 그라프트 重合의 動力學的 考察

全東源,吳賢理,兪惠子 梨花女子大學校 韓國生活科學硏究院 1986 韓國生活科學硏究院 論叢 Vol.38 No.-

단량체농도, 개시제농도, 그라프트반응시간, 반응온도등의 그라프트중합 조건을 변화시켜 가면서 poly (ethylene terephthalate) 필름에 styrene과 acrylid acid(AA)를 각각 그라프트중합시켰다. styrene단량체의 중합에서는 0.5×10^-2M/L~20×10^-2M/L의 농도범위에서는 그라프트중합속도가 styrene의 농도에 비례하지만 그 이상의 농도에서는 그라프트중합속도 R_p는 R_p=styrene^(0.4~0.45)로 표시된다. AA의 경우는 상당한 지연시간이 존재하지만 일단중합이 개시되면 중합속도는 styrene에 비해서 크다. styrene과 AA 전부에서 일정한 개시제농도 범위까지는 그라프트중합속도가 상승되지만 그 이상의 농도에서는 그라프트중합속도가 저하된다. Graft polymerization of acrylic acid (AA) and styrene on poly (ethylene terephthalate) <PET> film using benzoylperoxide <BPO> as initiator wasinvestigated under different conditions including monomer concentration, initiator concentration, graft polymerization temperature and time. With styrene, the rate of graft polymerization increases linearly as the concentration of styrene increase in the range of 5×10^-2M/L~20×10^-2M/L. The rate, however, is proportional to the 0.4~0.5 power of the styrene concentration above 20×10^-2M /L. With AA, there is a retardation period before the polymerization starts. Once the reaction is initiated, however, the rate of polymerization becomes faster than that with styrene. In both cases, the rates increase as the concentrations increase until certain points and the, they decrease thereafter.

This paper attempts to illuminate the differences in utterances between genders in language usage. The scope of the characteristics of utterances dealt with in this study is limited to the problems of difference in frequency of usage of certain expressions according to gender and differences in method of utterances. Differences in utterances between genders were noted in method of pronunciation, preferred vocabulary, and method of speaking. The point of view taken in investigating characteristics of utterances according to gender and in analyzing the results is significant. Then I discuss the method of investigating and the point of view in differences of utterances between genders. There is a need for objective research and objective point of view to reveal the differences in utterances between genders.

The purpose of the study is to compare the views of elementary school teachers and English conversation instructors on standards of professionalism in English class and to explore the meaning of “good” English classes. To accomplish the purpose, the survey was administrated to both 51 elementary teachers and 50 English conversation instructor groups. The results were as follows. First, when the views of both groups were compared, with the exception of four areas, elementary school teachers and English conversation instructors had similar views on “good” English classes. Second, when correlations among the four areas (i.e., knowledge, planning, praxis, and professionalism) comprising standards of professionalism in the English class at elementary school were investigated, there was indeed a correlation among the areas for both the elementary school teacher and the English conversation instructor groups. This means that both groups saw “good” English classes as being based not on any single area but on an organic relationship among the four areas. 본 연구는 초등학교에서 영어를 가르치고 있는 초등학교 교사와 영어 회화전문 강사의 ‘초등 영어과 수업 전문성 기준’에 대한 인식을 비교함으로써 좋은 영어과 수업의 의미를 탐색하고자 하였다. 이를 위하여 초등교사 51명, 영어 회화전문 강사 50명을 대상으로 5점 척도의 Likert Scale을 활용한 설문 조사를 실시하였다. 그 결과, 지식 영역의 ‘교과 내용’과 계획 영역의 ‘내용 선정·조직 및 학습목표 설정’ 영역과‘구조화된 수업 설계’영역에 있어서‘학습 목표 달성을 위한 학습 내용의 유기성과 단계성, 교수법·교수기법’과 관련된 문항에서 두 집단 간의 유의미한 차이를 나타냈다. 그러나 그 외의 영역에서는 두 집단 간의 인식이 비슷하였다. 영어 회화전문 강사가 비록 초등 정교사 자격증을 소지하지는 않았지만, 대부분 영어 교육 전공에 기반을 두고 있기 때문에 두 집단이 비슷한 인식을 가지고 있는 것으로 해석할 수 있다. ‘초등 영어과 수업 전문성 기준’을 구성하는 지식, 계획, 실천, 전문성 영역 간의 상관관계에서는 두 집단 모두 각 영역에서 상관관계가 있는 것으로 나타났다. 즉, 두 집단 모두 4개 영역이 유기적인 관계를 이루어 좋은 영어과 수업이 이루어지는 것으로 인식하고 있음을 알 수 있었다. 본 연구를 통해 탐색한 좋은 영어과 수업의 의미는 교원 자격 기준 및 영어과 수업 장학 등에 참고 기준으로 활용할 수 있을 것이다. 또한, 본 연구를 통해 좋은 영어과 수업의 의미는 지식, 계획, 실천, 전문성 네 영역이 유기적인 관계로 이루어지는 것임을 생각해 보는 기회가 될 것이다.

전희대,이성열,이혜진,박영립,이종석,황규왕 순천향의학연구소 1998 Journal of Soonchunhyang Medical Science Vol.4 No.2

In 3 months randomized, double-blind, vehicle-controlled study of retinol (vitamin A 0.1%-3000IU/g) in the treatment of photoaging skin, especially eye wrinkles. 24 patients applied retinol contained cream to the both eye wrinkles and vehicle cream(placebo) to the same site. Half of the patients received retinol contained cream and half received vehicle cream(placebo). All 24 patients who completed the study showed statistically significant improvement in photoaging eye wrinkles on the retinol contained cream treated group, but not on the vehicle treated group. Eight of the 12 patients who received retinol contained cream to eye wrinkles had improvement in photoaging, whereas only three of the 12 patients who received vehicle cream(placebo) improved. In retinol contained cream group, there is a some relationship between water contents and effects. In other words, as water contents were the higher, effects were the better. The side effects were limited to mild irritation of retinol contained cream treated skin. Retinol contained cream appeared to be safe and effective in the treatment of eye wrinkles.

연어 구성에 나타난 남녀 은유의 양상

전혜영 이화여자대학교 한국여성연구원 2005 여성학논집 Vol.22 No.1

본 논문은 한국어에서 '여자'와 '남자'가 어떤 개념으로 이해되고 있는가를 밝히는 것을 목적으로 한다. 일상 표현 속에 담김 은유를 파악함으로써 그 개념을 이해하는 방식을 알 수 있다는 관점을 수용하여, '여자'와 '남자'라는 단어가 어떤 동사와 결합하여 연어(collocation)를 구성하는지를 살펴보고 그 표현들을 대상으로 은유 방식을 찾아봄으로써 인식의 양상을 밝혀보고자 하였다. 한국어 용례 검색을 통하여 '(여자/남자)를 X하다' 연어 구성을 하는 자료를 수집하고 여기서 나타나는 남자와 여자에 대한 은유의 양상을 비교해 본 결과, [(여자/남자)는 물건] 은유, [(여자/남자)는 음식] 은유, [(여자/남자)는 동물] 은유, [(여자/남자)는 정복 대상] 은유, [(여자/남자)는 물질] 은유 등이 공통으로 나타났으며, 개념 이해 면에서는 남녀 차이를 보이지 않았으나, 은유의 유형과 빈도 면에서 남녀 차이를 보였다. The objective of his paper is to elucidate an understanding of the concept of 'woman' and 'man' in the Korean language. Acception the assumption that most ordinary conceptual systems find their essence in metaphors, this paper will investigate which words are collocated with the word 'women' and 'man'. By uncovering metaphoric forms using such expressions, the contemporary perceptions of women and man can be illuminated. Doing a search using Corpus, instances of usage of the linguistic formulation of 'woman/man' as the direct object in a sentence were compiled, and metaphors were identified and classified. In comparing how metaphors relating to women were applied to men, similarities and differences were recorded. The similarity found in the most common metaphors was [(woman/man) is an object] that women and men are often perceived as object. The next most prominent similarities were that: [(women/men) are animals], [(women/men) are food], [(women/men) are conquered objects], [(women/men) are a material substance]. These results show that the most common metaphors used regarding humans are those of objects, food, and animals. There are also no differences in the understanding of the concept of 'woman' and 'man'. However, they show some differences in frequency and types of metaphors using men and women as objects.
