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.

시간선호를 통해 본 노인의 경제적 의사결정 : 경제교육 필요성에 대한 함의

노인인구가 많아지는 우리 사회에서 노인들의 경제활동에 대한 관심이 높아지고 있으며 이에 따라 평생교육으로서의 경제교육에 대한 관심도 높아지고 있다. 이에 따라 본 연구에서는 노인인구의 경제적 의사결정의 특성을 이해하기 위해 노인들을 대상으로 시간할인율을 측정하여 노인들의 시간선호 특징을 파악하고자 하였다. 이를 통해 노인들의 합리적 경제 생활을 위한 경제교육의 필요성에 대한 함의를 도출하고자 하였다. 노인들의 시간선호의 특징을 살펴보기 위해 60세 이상 남녀노인 73명을 대상으로 경제실험을 실시하여 개인의 시간할인율을 측정하였다. 시간할인율은 개인의 현재지향적인 특성, 충동성, 자기통제력 부족, 근시안적인 성향 등을 설명하는 변수이다. 연구결과 노인은 청소년과 비교하였을 때 상대적으로 낮은 시간할인율을 보였다. 이는 청소년이 노인에 비하여 충동성이 높고 자기 통제력이 약하다는 점을 시사한다. 또한 본인의 노후시기 포함 여부 인식과 기대여명, 장애진단여부, 봉사활동 경험유무 등으로 노인집단을 구분하였을 때, 집단 간에 시간 할인율의 유의한 차이를 보였다. 본인이 노후시기에 포함되지 않는다고 인식하고 기대여명이 짧은 집단은 그렇지 않은 집단에 비하여 시간할인율이 높았다. 또한 장애진단을 받고, 봉사활동 경험을 가진 집단은 그렇지 않은 집단에 비하여 시간할인율이 높았다. 이상의 분석을 통해 노인경제교육을 포함한 평생경제교육 또한 미래지향적인 소비 생활을 이끌 수 있는 내용이 포함되어야 함을 이해할 수 있었다. This study focuses on older adults who are over 60 years old and investigates the relationship between time preferences and some related variables to understand the characteristics of elderly people's economic decision making. We investigate the time preferences of 73 elderly men and women living in Seoul by using the rate of time discount suggested by behavioral economics. The rate of time discounted is well known as an important explanatory variable that indicates an individual's impulsiveness, self-control, and present orientation. We discovered that older adults' average rate of time discount was lower than that of young adults, and this result was statistically significant. This result implies that aged people are less likely to be impulsive and more likely to show higher self-control. We also found that those who identify with the aged group and think that their remaining life is relatively shorter show higher rates of time discount than those who consider themselves still ‘not old enough’. In addition, older adults with disability also tended to show higher rates of time discount. This implies that lifelong economics education is needed to promote the ability of economic decision making with longer term perspective.

The acid value (AV) as well as the ester value of essential oil is an important index to evaluate quality of essential oil. The official standard analytical method of KS H ISO 1242 dealing with “Essential oils - Determination of acid value” was assessed experimentally using two lavandin essential oils obtained in France as an example. One French lavandin oil sample showed the results of AV= 0.9 by both indicator method and potentiometry. Another sample showed AV = 1.9 by indicator method and AV = 1.6 by potentiometry. Latter lavandin oil sample exhibited significantly higher acid value than maximum value of 1 described in the standard. This result suggests that latter lavandin oil was contaminated, because this oil was contained in an orange juice bottle. Results of this study proved that KS H ISO 1242 could be used as a suitable scientific standard for the determination of acid value of essential oils.

고등학교 토론 단원 교수ㆍ학습의 비판적 분석

김지현,전은주 부산대학교 사범대학 과학교육연구소 2012 교사교육연구 Vol.51 No.2

이 연구에서는 고등학교 국어 교과서의 토론 단원 통합 방식, 토론 지식의 설명 방식, 학습 활동의 타당성, 평가의 타당성 등에 대하여 비판적으로 분석하였다. 현재 국어과 교과서의 토론 단원 구성 방식을 ‘통합교육’이라는 측면에서 살펴보면, 토론 단원은 듣기, 말하기 영역의 통합과 여기에 더하여 읽기 영역이 통합된 것이 전부이다. 국어 능력의 총체적인 발달과 효율적 교수-학습을 위해, 쓰기와 문학과의 영역 통합도 가능하며, 말하기 또는 듣기 영역 내에서도 다른 성취 기준과의 통합도 가능하기에 보다 통합적으로 단원을 구성할 필요가 있다. 교과서 토론 단원에서 토론 지식을 설명하는 방법은 크게 ‘설명형’과 ‘요약형’으로 구분 가능한데, 대부분의 검정 교과서들이 ‘요약형’으로 제시함으로써 토론 지식을 단순히 정보 차원의 암기대상으로 다루는 문제점이 있었다. 이 논문에서는 교과서의 토론 단원에서 논제 분석과 토론의 유형과 절차 등 이해가 필요한 부분은 자세하게 ‘설명형’으로 제시하고 토론의 개념, 논제의 종류, 토론 참여자의 역할 등은 간략하게 ‘요약형’으로 제시하는 ‘혼합형’으로 제시하는 방법을 제안하였다. 이 연구에서는 토론 단원에 제시된 학습 활동의 타당성을, 교육과정에 제시되어 있는 여섯 가지 내용 요소를 기준으로 분석하였다. 분석 결과, 여섯 가지 내용 요소가 유기적으로 연결되어야 한다는 점, 활동이 정보 확인 차원에 머무르지 않고 실제적으로 학생들의 토론 능력을 향상할 수 있도록 활동을 구성해야 한다는 점, 학습자의 수준을 고려하여 충분히 상세하게 안내해야 한다는 점 등을 지적하였다. 이 밖에 이 연구에서는 교과서 토론 단원에 제시되어 있는 토론 평가 기준이 타당한가를, 평가 범주, 방식, 내용의 타당성을 중심으로 분석하고 그 문제점과 개선 방안을 제안하였다. This research critically analyzed the integration of the debate unit, explanations about debate knowledge, validity of learning activities and validity of assessment for high school. In terms of the integrated education for debate unit of Korean textbooks, the current debate unit is based merely on the integration of listening, speaking and reading. Integration of writing and literature is possible as well as that of listening and speaking. Besides, integrating other achievement standards under the same language skill is also possible. The way to describe the knowledge in debate consists of explanatory and summarizing types. Most approved textbooks employes summarizing type and regards the debate knowledge as what should be memorized. However, this study suggests that analysis of the discussion topic, types and procedures of the debate should be explained in detail (explanatory type), while the concept of debate, types of issues, and the role of participants should be given briefly in summary (summarizing type). The validity of learning activities in debate unit was analyzed on the basis of the six key elements of the curriculum. The authors pointed out that the six key elements should be organically connected, the activities should be organized practically in order to improve the debate ability of the learners, and detailed information should be provided with consideration of the learners’ level. Finally, the validity of debate assessment criteria provided in the debate unit of the textbooks was analyzed in terms of assessment categories, assessment methods and the validity of the contents.

The purpose of the study was to investigate the effect of image ability and factor of anxiety upon the dancing performance. Investigated Surveyed were 60 girls enrolled in the 2nd grade of Y Middle School located in K City taken as population. They were divided into the physical training group, physical video image training group and control group with 20 assigned to each group at random. The sence of anxiety between these treatment groups before and after the dancing repeat motion was compared and analyzed, Which leads to the following conclusion: First, an negatively proportional correlation of r=.34, p<.05 was found between sport image ability and factor of anxiety, a statistically significant relation to justify. Second, regarding the effect of test treatment on the factors governing the factor of anxiety, the physical training group falls from 46.05 before the treatment to 45.75±2.49 after the treatment, a slight decrease with little statistical significance. On the other hand, the physical video image training group showed a drastic fall from 46.25±2.51 before the treatment to 40.20±2.53 after the treatment, with t=7.89, p<.001 being statistically significant.

The purpose of this study was to investigate the patterns of the health related variables, and physical characteristics and physical fitness of the elderly people in order to provide a exercise program. The data about the health related variables were collected through the personal interview, and the data about physical charateristics and physical fitness (height, weight, % body fat, blood pressure, pulse rate, grip stength, trunk flexion, side step test, 2 min, harvard step test) of 373 elderly people living Seoul and kyungkee area were collected. The conclusions of this study can be summarized as follow; 1. The test results about smoking, drinking, sleeping and self-evaluation of health revealed that the elderly people have self-confidence about their health. 2. Not many elderly people participate the proper exercise program even though they recognize the need of exercise. 3. The results showed that the elderly people do not pay much attention to the intensity of the exercise. 4. Muscle strength training for leg and the lower back and cardio-vascular endurance training was recommended to reduce the risk of varius problems caused by aging. 5. A exercise program was suggested for the elderly people.

무증상으로 발견된 담낭-담관 누공을 동반한 Mirizzi 증후군 1예

홍진희,전태주,서지영,서동대,오태훈,신원창,최원충,신은아,김기환 인제대학교 2009 仁濟醫學 Vol.30 No.-

Mirizzi's syndrome is a rare complication of the gallstone disease, characterized by narrowing of the common bile duct (CBD) due to chronic extrinsic compression of an impacted gallstone in the cystic duct or the neck of the gallbladder. The impacted gallstone may erode into the bile duct, causing cholecystocholedochal fistula. The patients generally have history of repeated attacks of jaundice and abdominal pain. But there is no report about asymptomatic Mirizzi syndrome with cholecystocholedochal fistula which were found incidentally. So herein we present our clinical experience with a case of asymptomatic Mirizzi syndrome with cholecystocholedochal fistula in a young female.

김문연,고은하,하경임,김지용,전창호 동국대학교 경주대학 1996 東國論集 Vol.15 No.-

검사방법의 평가로서 자동화기기에 대한 적절한 평가는 특히 수입에 전적으로 의존하는 국내여건을 생각할때 중요한 과제이다. ISP-1000은 대용량, 다항목의 선택적 생화학 자동 분석기로 국내에서는 거의 채택된 경험이 없는 기기로서 효율적인 선정을 하기위하여 4가지 화학검사에 대한 평가를 하였다. 시판되는 대조물질 Level Ⅰ,Ⅱ로 검사내 정밀도, 검사일간 정밀도, 직선성을 구하였으며 100명의 환자검체로는 Cobas Mira와의 상관성을 구하였다. 검사내 정밀도는 Level Ⅰ대조물질에서는 변이계수가 4.31-8.73%, Level Ⅱ 대조물질에서의 변이계수는 1.32-8.22%이었으며, 검사일간 정밀도는 Level Ⅰ 대조물질로 얻은 변이계수는 6.29-8.974%, Level Ⅱ 대조물질로 검사한 경우는 5.78-8.22%이었다. 직선성의 평가에서는 0.9917-0.9998의 우수한 직선성을 보여주었고(P<0.01), Cobas Mira에 대한 상관관계는 0.8427-0.9857의 범위에 있었다(P<0.01). 결론적으로 ISP-1000에 대한 4가지 화학검사의 평가에 있어서 검사중 정밀도, 검사일간 정밀도, 직선성은 우수하였으며, 상관관계는 만족할만하였으나 더 좋은 결과를 얻기위하여 parameter등에 대한 재검토가 필요한 것으로 생각되었다. It is an important task to evaluate autochemical analyzers as one of the labortory method evaluations, especially considering of the domestic environments almost depending on the import. By analyzing 4 chemical tests, we evaluated the high throughoutput, multichannel, selective and rarely adopted chemical autoanalyzer ISP-1000. We analyzed within run precision, between day precision, lineality with the commercial control materials, and correlation with 100 patients samples. In within run precision, CVs were ranged from 4.31~8.73% in Level I control material, l.32-8.22% in Level Ⅱ control material. In between day precision, CVs were ranged from 6.29-8.974% in Level I control material, 5.78-8.22% in Level Ⅱ control material. The lineality was excellent(r²>O,9917, p<O.Ol). The correlation coefficients between ISP-l000 and Cobas Mira were ranged from 0.8247∼0.9857%(P<O.0l). In conclusion, 4 chemical tests of ISP-l000 were acceptable in within run precision, between day precision and lineality, and correlation with Cobas Mira was good but adjusting the parameters would be necessary for the better results.

한국인의 대표적인 성인 고형 종양인 위암, 간암, 유방암과 소아 백혈병 및 2종의 소아 고형 종양 환자로부터 혈장 transforming growth factor-ß1 (TGF-ß1) 농도를 sandwich ELISA 분석법을 이용해 측정함으로써 TGF-ß1을 이 질환들에 대한 새로운 종양표지자 (tumor marker)로 사용할 수 있는지 검토하였다. 또한 연령 및 성별에 따른 혈장 TGF-ß1 농도의 정상치를 조사하였다. 신생아에서 70대까지 혈장 TGF-ß1 농도의 차이는 없었고 남녀간의 차이도 없었다. 위암 환자의 혈장TCF-ß1 농도는 16.0±6.8 ng/ml (평균 ±표준편차)로 정상 대조군의 TGF-ß1 농도 (8.3 ±5.0 ng/ml) 보다 유의하게 높았으나 간암, 유방암 환자의 혈장 TGF-ß1 농도는 대조군과 차이가 없었다. 그리고 위암 환자 16명, 간암 환자 8명, 유방암 환자 7명 중 각각 7명 (43.7%), 1명 (12.5%), 1명 (14.3%)에서만 혈장 TGF-ß1 농도가 증가되었다. 5명의 소아 백혈병 환자에서는 관해 (remission) 여부와 상관없이 혈장 TGF-ßl 농도가 모두 정상 범위에 있었으나 2명의 소아 고형암 환자에서는 종양 절제 전에는 혈장TGF-ß1 농도가 높았다가 절제 후 정상으로 떨어졌다. 결론적으로 1)정상인의 혈장 TGF-ßl 농도는 연령 및 성별에 따른 차이가 없다는 것을 알 수 있었고, 2)성인 고형암인 위암, 간암, 유방암에서는 낮은 민감도로 인해 TGF-ß1을 진단을 위한 선별 검사로 이용하기에는 부적절한 것으로 판단되었으며, 3) 정상 대조군보다 혈장 TGF-ß1 농도가 높았던 위암 환자와 종양 절제 전후로 혈장 TGF-ß1 농도가 민감하게 변했던 소아 고형 암 환자에 대해서는 향후 표본 수를 늘려 부가적인 연구를 해 야 할 것으로 사료된다. To evaluate the usefulness of transforming growth factor-ß1 (TGF-ß1)as a new tumor marker, we determined the plasma TGF-ß1 levels using sandwich ELISA assay in cancer patients. Patients with three most common adult cancers in Korea (stomach, liver and breast cancer) and children's cancers (leukemia and two kinds of solid tumor) were enrolled for the study. Furthermore, 39 individuals were subjected to age and sex-stratified plasma TGF-ß1 analysis. No statistical difference was demonstrated with respect to age or sex. The mean plasma TGF-ß1 level (16.0 ng/ml) of stomach cancer patients was significantly higher than that (8.3ng/ml) of controls. However, there was no difference among the mean plasma TGF-ß1 levels of liver, breast cancer patients and controls. Seven of 16 patients (43.7%) with stomach cancer, one of 8 (12.5%) with liver cancer, and one of 7 (14.3%) with breast cancer showed higher TGF-ß1 levels compared to controls. Plasma TGF-ß1 concentrations of five leukemic children remained in the normal range regardless of the remission state. In contrast, initial high TGF-ß1 levels from two children with solid tumors returned to normal range on surgical resection of tumors. From the above results, we could conclude that plasma TGF-ß1 levels of apparently healthy individuals seem to be rather constant irrespective of difference in age or sex, and the plasma TGF-ß1 has the limited value as a screening test for the diagnosis of aforementioned adult cancers because of its low sensitivity. Finally, additional studies need to be pursed for the large number of stomach cancer and pediatric solid tumor patients in order to reach a secure conclusion on the usefulness of plasma TGF-ß1 as a tumor marker in these patients.
