강명희,김래연 한국교육정보미디어학회 2000 교육정보미디어연구 Vol.6 No.2

본 연구는 웹 기반 학습에서 정보 리터러시 수준을 향상시키기 위한 방안으로 과거 연구들이 제시하고 있는 Eisenburg의 "Big6 정보 리터러시 모델"을 효과적으로 활용할 수 있는 방안을 제시하기 위해, Big 6 모델을 활용한 학습 상황에 참여한 학습자의 메타인지 수준과 정보문제 해결 능력간의 상관관계를 분석하였다. 연구 결과는 첫째, 메타인지 수준과 정보문제 해결 능력 사이의 상관관계는 통계적으로 유의미한 정적 관계가 있는 것으로 나타났다(r = .337, p< .05). 둘째, 메타인지의 4가지 하위요소(인식/인지전략/계획/모니터링)와 단계별 정보문제 해결 능력인 과제수행활동(자료수집/정보활용/정보창출)간의 상관관계 분석결과 메타인지의 4요소 중 모니터링 수준은 3단계의 과제수행 활동 모두와 유의미한 상관관계를 보이는 반면, 인지전략수준은 반대로 어떤 단계의 활동과도 통계적으로 유의미한 상관관계를 나타내지 않았다. In today's information society, not only the ability to utilize various types of information technology but also 'information literacy', which is making strategic plan and tracking down information in order to solve the problem at hand, distinguishing searched information critically and using only useful and trustworthy information, is recognized as the most fundamental yet kernel acquirements. The purpose of this study is to analyze the correlation between learner's metacognition level and ability to solve information problems in the learning environment of "Big6 model" application suggested by Eisenburg as a way to improve information literacy, and to execute a more detailed study of concretely suggesting effective utilizing subjects by clarifying in which level of learners as targets the classes applied with information literacy model is most effectively utilized. Subjects of this study are 50 students of the university students. A workbook that introduces Big6 information literacy model were provided as a 'task executing guide' in the internet lecture room so that learners can apply it to execute the task of solving information problems. The results are as the following: First, the level of the learner's metacognition showed to be in a statistically significant correlation to capability to solve information problems. (r = .337, p< .05) Second, the 'awareness' levels among subordinate factors of metacognition showed to be in a statistically significant correlation with 'information utilization' activity among the 3 stages of task execution. (r=.303, p< .05) Third, the 'cognitive strategy' among 4 subordinate factors of metacognition showed not to be in a significant correlation with any of the stages of task execution. Fourth, in correlation between the 'planning' and information problem solving capability, only the correlation between information creation activity showed to be statistically significant. (r=.347, p< .05) Fifth, the 'self-monitoring' level showed to be in a statistic correlation to all 3 stages of execution process of solving information problems. Based on the result of this study, following suggestions were made: First, studies that verify the relationship between various cognitive characteristics of the learners' that have not yet considered or learning styles and information problem solving abilities in study environment with an information literacy model application should be continuously achieved. Second, in order to judge more accurately about the correlation between the effects of Big6 model and learners' metacognition levels, the correlation between the metacognition levels and task execution capabilities should be examined more concretely through simultaneous study of comparison with the environment without the model application.

The purpose of this study was three fold: to take the measurements of dress form according to the size, to compare the size of bodice pattern made by draping and flat pattern method. and to disclose the problem of dress form through comparison of measurements of body and dress form. 163 samples of dress form size from 6 to 10 were selected and 16 items on the dress form were measured. A draping method and two different flat pattern method (pattern A and B) were used to compare the patterns. For the draping method, one representative dress form each size number 6 to 10 was selected and standard dress form which was made for this study based upon the standard size of women in twenty years of age was used. The results of the study were as follows: First, the size of dress form ranging from 6 to 10 were generally used in the universities. Particularly, the size 6 and 8 which were ideal as body sizes for college women were mostly used. Second, there were significant differences in waist dart and low-underarm dart between the draping and the pattern A. There was no significant difference in the comparison of dart between the draping and the pattern B. Third, back neck girth, back neck width, front-side line grade, and back shoulder grade were found to be greater in the draping pattern than the patterns A and B. Pattern A and B were wider than the draping pattern in front-armhole girth, total-armhole girth, front neck depth, front-armhole depth, and back-armhole depth. Front neck girths and front shoulder grade were wider in the pattern B than the draping. Fourth, when the bust girth was compared to the waist, hip, and neck girth, and shoulder width, the ratio of the dress form was similar to that of standard, but generally the measurements of each item on the dress form were smaller than the standard, showing a great difference in the shoulder width. The back neck width of the dress form was wider, and the front neck depth of the dress form narrower than the actual body. Therefore, especially it is necessary to consider the average neck size of body to make dress form.

For an increase of body weight, feed efficiency, and profitability of Korean cattle fattening through the effective fattening of the Korean cattle concentrates with an addition of 0.05 mg of cobalt for test plot I, 0.05 mg of cobalt for test plot II 0.10 mg, and 0.15 mg for test plot III, per kg of concentrate were given to sampled cattle. Experiments were designed to repeat control plot and three test plots (I, II, III) five times far 140 days on the 20 cattle sampled by completely randomized design. The results of the experiments are presented in the following. I. Amount of Body Weight Gain The average weight gain per head, and weight gain per day are commonly highest in the test plot II (132.6 kg ㆍ 0.92 kg), second in the test plot I (128.5 kg ㆍ 0.91 kg), third in the test plot III (121.1 kg ㆍ 0.87 kg), and lowest in the control plot (120.4 kg ㆍ 0.87 kg). The rull hypothesis was accepted while there was no statistical significance between the test plots and the control plot, and also among the test plots. But the test plots with an addition of cobalt resulted in higher gain of body weigh comparing to that of the control plot. II. Amount of Feed Intake and Feed Effeciency The efficiency of concentrate required to increase on Kilogram of beef was highest in the test plot II 6.42 kg, second in the test plot I 6.53kg, third in the test plot III 7.00 kg, and lowest in the control plot 7.18 kg respectively. In case of flay and pellets the test plot I showed the highest weight gain, the test plot II, and III resulted in the same performance, and the control plot was the lowest one in the gain of body weight. There was no statistical significance between the test plots and control plot, and among the test plots. Thus, the test plots with ail addition of cobalt comparing to the control plot resulted in a higher feed efficiency. III. Profitability Feed costs required to increase one Kilogram of fresh meat was 636 casts won in the test plot II, 641 won in the test plot I, 685 fresh meat won in the test plot III, and 703 won in the control plot respectively. While there was no statistical significance with profitability, the test plot with an addition of cobalt required lower feed cost increase one kilogram if fresh meat comparing to the control plot. IV. Fattening outcome Of the sampled 20 cattle 18 cattle were slaughtered after 6 days from the last day of the tests. The carcass rate of the sloughtered cattle was 56.4 percent in the test plot II, 55.0 percent in the test I, 54.8 percent in the test plot III, and 54.6 percent in the control plot. There was no statistical significance with the rate of carcass, but the test plats with an addition to cobalt presented a little higher carcass rate comparing to the control plot. It was rather difficult to distinguish meat color with eyes, but comparing to the control plot the meat color of the test plots was heavily red.

The effects of cisplatin on the IgM plaque forming cells and the lymphocyte proliferation in primarily sensitized mice were investigated. Cisplatin was i.p. injected with a single low does (0.825, 1.65, 3.3mg/kg, which is 5, 10, 20% of LD_50) to mice. The splenic IgM antibody plaque forming cell (PEC) was assayed after ICR mice had been treated in vivo with a combination of three different doses of Cisplatin at different time (day-2, day+2) plus SRBC(day 0). IgM PFC was significantly increased when drug was injected prior to immunization with SRBC, but it was decreased when administered after SRBC antigen. Splenocytes from mice injected with Cisplation(1.65, 3.3mg/kg) on the 2nd day before the test day were cultured with Con A and LPS. The splenocyte proliferation to Con A mitogen was slightly increased, but to LPS was significantly and markedly increased. It was found that Cisplatin at low dose showed either immunosuppression or immunostimulation, depending on the time of drug-application in relation to antigenic treatment.

오명돈,최강원,신형식,김성민,최희정,강현재,김윤준,채종일 대한감염학회 1996 감염 Vol.28 No.5

Cryptosporiduim is an intracellular protozoan parasite and known as an important pathogen causing diarrheal illness in animals and man since 1970's. With the advance of epidemic of Acquired Immunodeficiency Syndrome(AIDS), Cryptosporidium has emerged as one of important pathogens in AIDS patients and is responsible for chronic diarrhea, cholecystitis, biliary tree obstruction and respiratory illness. Despite frequent reports of cryptosporidial diarrhea in other countries there has been no report of human cryptosporidial infection in AIDS patients so far in Korea. We report two cases with chronic cryptosporidial diarrheal illness in AIDS patients. C. parvum oocyst was identified by fecal smear with modified acid fast staining. In one patient the diarrheal illness was improved after 4 weeks supportive management only. But fecal excretion of oocyst continued after clinical improvement of the diarrheal illness. Another patient was died of respiratory failure after recurrent diarrheal illness. Cryptosporidial infection should be considered in differential diagnosis of chronic diarrhea especially, in AIDS patients.

A study has been performed on the characteristics of rural and urban surface ozone concentration for the period of March 1992 to February 1993. The monitoring station of rural ozone is located at Kosan, Cheju and other urban monitoring stations are located at Seoul, Pusan and Kwangju. Rural's and urban's ozone data exhibit a distinct features in many ways. First, annual mean of rural ozone concentration is very high(42 ppbv) but urban's are very low(10~15 ppbv). Second, rural ozone data shows a seasonal variation with it's maximum in spring, and minimum in summer, but urban's show a seasonal variation with it's maximum in spring, and minimum in winter. Third, diurnal variation of rural data is very small but that of urban's are very large. Fourth, monthly mean of daily minimum of rural data is not low and shows a large seasonal variation, but those of urban's data are extremely low(<3 ppbv) and have no seasonal variations.

김경희,강진경,문영명,송경순,김용범,최흥재,황용 대한내과학회 1986 대한내과학회지 Vol.30 No.1

Testing for IgM antiHBc was useful to detecting the patients with negative and positive HBsAg viral hepatitis and may improve serodiagnostic accuracy when acute NANB and delta agent hepatitis occur in previousely unrecognized HBsAg carriers. Moreover, it may be a useful test in defining potentially high risk sources of exposure to hepatitis B virus. But it is not useful in distinguishing recent from remote infection because IgM antiHBc occasionally was found in chronic liver diseases, IgM antiHBc was found by ELISA in 32 patients with acute viral hepatitis B, 61 with chronic hepatitis B, 18 patients with liver cirrhosis, 36 healthy HBsAg carriers and l49 patients with positive antiHBc alone. We continuously evaluated HBsAg and liver function of the patients who had negative IgM antiHBc acute hepatitis. The results are summarized as follows: 1) IgM antiHBc was positive in 84.4% of acute hepatitis B, 4% of chronic hepatitis B, 5.5% of positive HBsAg liver cirrhosis, 2. 8% of HBsAg healthy carriers but was all negative in patients with positive antiHBc alone. 2) Three patients with negative HBsAg acute viral hepatitis was diagnosed by positive IgM antiHBc as acute viral hepatitis R. 3) During the follow-up of 5 patients with negative IgM antiHBc acute hepatitis, 2 patients were diagnosed as type B acute viral hepatitis because of disappearance of HBsAg and normalization of liver function. And another 3 patients were diagnosed as non-B acute viral hepatitis superimposed on HBsAg carrier or natural course of chronic hepatitis.

박완범,강철인,김동민,이기덕,장희창,김홍빈,오명돈,이효석,최강원 대한감염학회 2003 감염과 화학요법 Vol.35 No.5

목적 : C-reactive protein(CRP)은 간에서 생성되는 급성 반응물질이다. 하지만 간부전증 환자에서 CRP의 반응이 간기능에 따라 어느 정도 영향을 받는지는 별로 알려진 바가 없다. 본 연구에서는 간기능에 따른 CRP 생성 능력을 평가하고자 하였다. 방법 : E. coli 균혈증이 있는 간경변증 환자 30명을 대상으로 하였고 간기능은 균혈증이 발생하기 전 2개월 이내에 측정된 혈청 빌리루빈, 혈청 알부민, 프로트롬빈시간, Child-Pugh 점수로 평가하였다. 대조군 A는 간질환이 없으면서 E. coli 균혈증이 발생한 환자 30명으로 하였고 대조군 B는 간경변증이 있으면서 급성 감염의 증거가 없는 환자 30명으로 하였다. 환자군과 대조군 간에 CRP의 최대값을 비교하였다. 결과 : CRP의 최대값은 환자군에서 7.3±5.0㎎/dL, 대조군 A에서 17.9±8.3㎎/dL로 환자군에서 유의하게 낮았다.(P<0.001). 간경변증 환자에서 CRP의 생성은 Child-Pugh 점수에 비례하여 감소하였으나(P=0.004) Child=Pugh class C의 간기능을 가진 환자군에서도 대조군 B와 비교하여 의미있는 CRP의 생성을 보였다(5.3±3.2 vs. 0.5±0.4㎎/dL, P<0.001). 결론 : 간기능부전 환자에서 CRP 반응은 간기능 저하 정도에 따라 둔화되지만 심한 간기능 장애를 가진 환자에서도 CRP의 생성은 유지된다. Background : C-reactive protein (CRP) is an acute phase reactant produced in the liver. To assess the influence of liver dysfunction on the production of CRP, we evaluated CRP response to E. coli bacteremia in patients with or without liver cirrhosis (LC). Methods : 30 LC patients who developed spontaneous peritonitis with E. coli bacteremia were enrolled in the study. Baseline values of total bilirubin, serum albumin, and prothrombin time were obtained within 2 months prior to infection. Liver dysfunction was categorized according to the Child-Pugh score. 30 patients with E. coli bacteremia who had no underlying liver dysfunction were included as a control group. Matched-control of 30 LC patients without evidence of acute infection was also included. The peak CRP values were compared among the groups. Results : In the patients with E. coli bacteremia, the mean value of peak CRP was 7.3 (+/- 5.0) ㎎/dL in LC patients, 17.9 (+/- 8.3) mg/dL in patients without liver dysfunction (p<0.001). In the advanced LC patients with Child-Pugh class C, the level of CRP was 5.2 (+/- 3.3) ㎎/dL in patients with E. coli bacteremia, 0.5 (+/- 0.4) ㎎/dL in patients without acute infection (P<0.001). Child-Pugh score had correlation with decrease of CRP (linear regression test, P=0.004). Conclusion : CRP response during E. coli bacteremia was attenuated but maintained even in patients with advanced liver dysfunction.
