批判的 思考의 本質과 批判的 思考敎育에 관한 探究

신동로,오현수 全北大學校 敎育大學院 1998 敎育論叢 Vol.18 No.-

The purpose of this study is to examine the history of the terms 'a critical thinking' and to survey the nature and the education of one. The critical thinking movement seems to have begun with the work of John Dewey from 1910 to 1939 and his use of the terms 'reflective thinking' and 'inquiry' which he based on the scientific method. From 1940 to 1961, the meaning of the term 'critical thinking' broadened to include the examination of statements. From 1962 to 1979, The meaning of the term 'critical thinking' narrowed to exclude problem solving and the scientific method and include only the assessment of statements. With the contributions of Robert H. Ennis, John E. Mcpeck. Harvey Siegel, and Richard W. Paul from 1980 to the present, the meaning of the term 'critical thinking' has broaden to include aspects of problem solving. The meaning of the terms 'critical thinking' and 'problem solving' overlapped and intersected each other. The core meaning of the critical thinking is the propensity and the skills for participate in the thinking activities with the reflective skepticism about the objects of thinking within one's cognizance. The aims for the teaching of critical thinking and reasoning is to be well used the logical skills to judge about the decision-making and problem solving situation. Formal and informal logical education is essencial to success for the education of critical thinking. The education of critical thinking have to be learned through the debate and the discussion.

The purpose of this study was to offer gymnasts data for successfully performing triple back somersault dismount(TBSD) and for designing training programs to progress gymnasts to the advanced dismount skills from the horizontal bar through comparative analysis of selected biomechanical factors of single back somersault dismount(SBSD), double back somersault dismount(DBSD) and TBSD. The subjects employed were a total of 4 male middle and high school gymnasts aged between 15 and 16 years. A motion-picture camera, fliming at a nominal rate of 54 frames/s, was used to record the performance of subjects on each trial. This camera was placed at a distance of 15 m from the inward pole of horizontal bar with its optical axis at right angle to this pole. The results obtained are summarized as follows: The mean release angle was 80.5° for the SBSD, 77.3° for the DBSD and 71.3° for TBSD. There were significant differences between the SBSD and the TBSD(p<0.01), the DBSD and the TBSD(p<0.05) but no significant difference between the SBSD and the DBSD. The angular velocity at release was 4.533 ㎭/s for the SBSD, 5.338 ㎭/s for the DBSD and 6.020 ㎭/s for the TBSD. There was a significant difference among these velocities(p<0.05, p<0.01). The linear velocity at release was 5.458m/s for the SBSD, 5.750m/s for the DBSD and 6.083m/s for the TBSD. In this case, we had a significant difference only between the SBSD and the other two somersaults(p<0.05, p<0.01). The shoulder angle at release was 170.5° for the SBSD, 167.0° for the DBSD and 154.3° for the TBSD. There were significant differences between the SBSD and the TBSD(p<0.05), the DBSD and the TBSD(p<0.05) but no significant difference between the DBSD and the TBSD. The hip and knee angle at release were increased respectively by increasing the number of somersault but showed no significant difference among these angles. The mean flight time from release to landing for each somersault was calculated; it took the subjects 1.315s to perform the SBSD, 1.345s to perform the DBSD and 1.416s to perform the TBSD. There was a significant difference among these somersaults with respect to time(p<0.05, p<0.01). The mean maximum height was 3,633m for the SBSD, 3,720m for the DBSD and 3,780m for the TBSD. There was a significant difference only between the SBSD and the other two somersaults. The mean horizontal distance was decreased respectively by increasing the number of somersault but showed no significant difference among these somersaults with respect to distance. The smallest hip angle during flight in the SBSD was 115.3° at 0.317s after the subject left the bar, for the DBSD it was 48.2° at 0.621s while that of the TBSD was 32.3° at 1,102s after release. The relationship between the time the smallest hip angle observed and the total flight time was determined; it took 24.1% of the total flight time of the SBSD to reach the smallest hip angle. In the DBSD, it took 46.2% of the total flight time to reach for the smallest hip angle and in the TBSD 77.8% of the total flight time to reach the smallest hip angle. From the above results, the gymnast would need to (1) increase angular velocity before release by manipulating of body shape, (2) change the release angle and (3) stay tuck position longer by shortening as quickly as possible the angle of each body joint to perform successfully the TBSD. Also to be able to perform quadruple back somersault dismount, a gymnast would need flight time of a minimum 1,782s.

Mucoepidermoid carcinomas, first reported by Volkman(1895), form 6% to 9% of all salivary tumors. Two thirds affecting the parotid gland and the remaining third, the minor glands. As we could know from its name, mucoepidermoid carcinomas originate from ductal epithelium including squamous, mucous-secreting, and undifferentiated intermediate cells. Histologically, it is classified as well-differentiated (low grade), moderately-differentiated(intermediate grade), and poorly-differentiated (high grade) types and the treatment method and prognosis are influenced from its histological grade. We have experienced two cases of mucoepidermoid carcinoma treated surgically with good results and now would like to report these with review of literatures.

Zeolite의 性質硏究

吳英敏,申東英 東亞大學校 1978 東亞論叢 Vol.15 No.2

The laboratory experiments on the basis of cation exchange of zeolites were carried out to remove ammonia nitrogen adn trace heavy metals from water using the natural zeolites produced at Youngil and Weolseong. And some results obtained are summarized as follows: 1. X-ray diffraction showed that zeolites heated to the temperature over 800℃ for one hour were decomposed in its crystal structure. 2 The constants in the Freundlich adsorption isotherms for the metal ions show the adsorption of lead ion is the best of the four metal ions: Cu, Pb, Cd, and Cr. 3. Time for adsorption of the heavy metals is less than 60 minutes with 150 rpm in a batch system. 4. The optimum pH for adsorption of the heavy metal ions was 6 to 7; in lower than pH4 it showed poor adsorption adn in higher than pH7 hydroxides of the metals occurred. 5. Ion selectivity of the zeolites was shown in order of Pb++> Cr++ > Cu++ > Cd++. 6. Regeneration of the ammonium zeolites (spent zeolites) by heating at 700℃ is the most effective in reuse of it with having ammonia removal rate of more than 50 per cent.

After performing mandibular setback surgery, we found some changes in patterns and organs of speech. This investigation was undertaken to investigate the aspect and degree of speech patterns according to the amount of surgical setback in mandibular prognathic patients. Thirteen patients with skeletal Class Ⅲ malocclusion were studied preoperative and postoperative over 6 months. They had undergone the mandible setback operation via bilateral sagittal split ramus osteotomy(BSSRO). We split the patients into two groups. Group 1 included patients whose degree of mandibular setback was 6mm or less, and Group 2 above 6mm. Control group was two adults wish normal speech patterns. A phonetician performed narrow phonetic transcriptions of tape-recorded words and sen- tences produced by each of the patients and the acoustic characteristics of the plosives, fricatives, and flaps were analyzed with a phonetic computer program (Computerized Speech Lab(CSL) Model 4300B(USA) ). The results are as fallows : 1. Genera1ly, Patients showed longer closure duration of plosives, shorter VOT(voice onset time) and higher ratio of closure duration against VOT 2. Patients showed more frequent diffuse distribution than the control group in frication noise energy of fricatives. 3. In fricatives, frequency of compact from were higher in group 1 than in group 2. 4. Generally, a short duraction of closure for /ㄹ/ was not realized in the patient's flaps. Instead, it was realized as fricatives, sonorant with a vowel-like formant structure, or trill type consonant. 5. Abnormality of the patient's articulation was reduced, but adaptation of their articulation after surgery was not perfect and the degree of adaptation was different according to the degree of surgical setback.

pH 7.4, 37℃의 생리적 반응조건에서 HSA, ovalbumine, BSA, lysozyme, RNase A 및 IgG와 3-deoxyglucosone을 반응시키고 단백질의 중합현상과 아미노산 잔기의 손상상태를 연구하였다. 3-deoxyglucosone은 모든 단백질을 중합시킬 수 있으나 특히 lysozyme, RNase A 및 IgG를 현저하게 중합시켰다. 또한 Arginine잔기를 크게 손상시켰다. glucose에 의한 단백질의 중합과정은 glucose가 단백질의 아미노 그룹과의 반응으로 3-deoxyglucosone을 형성시키고, 이것이 단백질의 lysine 잔기와 arginine 잔기를 공격하여 cross link를 형성시키는 것으로 추정되었다. Human serum albumin, bovine serum albumin, ovalbumin, IgG, lysozyme and ribonuclease A were reacted with 3-deoxyglucosone under physiological conditions of 37℃ and pH 7.4, and polimerization of proteins and impairments of amino acid residues were investigated. Proteins tested, especially lysozyme, IgG and ribonuclease A, were polymerized significantly, and lysine residue and arginine residue, espectially arginine residue of proteins were impaired remarkably. Experimental results strongly suggested 3-deoxyglucosone, formed from proteins-glucose reaction system, was the cross-linker responsible for the polymerization of proteins.

In this study, the variation of water quality in Aswan stream was investigated through continuous monitoring and matt balance and metabolism occurred into water body environment was estimated to set up effective management plan of small urban stream. Sated on the results, the rate of output to input (O/I rate. in the flux balance was 1.16 and about 16% sae increased between the section of OS1 ∼ OS3. Also, the SS and BOD loadings between the tame section were increased by 29% and 31%, respectively. Although increase of flux influenced on the increase of SS and BOD loading, it was judged that the larger part of o/I rate of pollutants comparing to O/I rate of flux was due to up-take from sediment on the riverbed. The contribution percentage of BS1 and BS2 for flux between the section of OS1 ∼ OS2 was 17.3%, total section was 31.3% (including BS3). However, the contribution of tributaries for SS, BOD and T-N loading wore 50.3%, 33.0% and 57.6%, respectively. Eventually tributaries contributed the pollution of water quality. To reduce pollution of water quality in the section of OS1 ∼ OS3, firstly, it need that effective management plan for tributaries mutt be set up to improve the water quality in main stream. Secondly, the counter plan for ro-eruptyon of pollutants from sediment in main-stream it required to prevent inner pollution. On this study, we showed that small urban stream can be managed effectively by simple investigation to prevent deterioration of water quality. also, it is more important that matter cycle and matt balance happening in the stream environment must be correctly estimated to make up healthy stream environment and to improve water quality.

The authors experienced a female schizophrenic patient who revealed severely decreased leucocytes (350/㎣) with the manifestation of high fever, chillness and sore throat after the oral administration of neuroleptics. Agranulocytosis induced with the use of neuroleptic drugs has been well known complication in psychiatric practice although it is quite rare. In this case, following the combined use of neuroleptics (thioridazine halopondol and chlorproonazine), severe decrement of leucocytes (mainly lymphocytes with few neutrophils) was noticed on peripheral blood and marked decrement of erythroid series, especially of myeloid series, with decrement of total cellular elements were confirmed through the biopsy of bone marrow. She did not responded at all to the massive administration of antibiotics, but dramatic improvement was noticed both clinically and in the follow-up biopsy findings of bone marrow after two times trial of leukapheresis.
