The purpose of the present study is to determine the levels of maximal oxygen uptake and anaerobic threshold of boxing players(n=23), ken-do players(n=18), Judo players(n=12), T.D.K players(n=18). Treadmill test was used to measure maximal state and anaerobic threshold of metabolic variables. Treadmill exercises protocol was 2-min incremental test from an initial work load of 0MPH(grade : 0%) to all-out by step of 1.0MPH(grade : 2%). The results of measurement was as follows : 1. Absolute(1/min) and relative(ml/kg/min) maximal oxygen uptake was highest(5.08l/min, 65.01 ml/kg/min) in Judo layers, followed in order by the T.D.K players (4.37l/min, 64.74 ml/kg/min), Boxing players(4.18) l/min, 63.19 ml/kg/min) and ken-do players(3.81l/min, 58.65 ml/kg/min). It is not significant difference in the relative maximal oxygen uptake, but is significant difference between group in the absolute maximal oxygen uptake(p<0.001) 2. AT-VO₂(l/min) and AT-VO₂(ml/kg/min) in the anaerobic threshold was highest (3.71 l/min, 47.28 ml/kg/min) in Judo players, followed in order by the T.K.D players(3.29 l/min, 48.75 ml/kg/min), boxing players(2.90 l/min, 43.91 ml/kg/min) and ken-do players(2.82 l/min, 43.52 ml/kg/min). It is not significant difference in the AT-V02(ml/kg/min), but is significant difference between group in the AT-V02(l/min). (p<0.001) 3. %HRmax and %V 02max in the anaerobic threshold was not significant difference between group.

Jude the Obscure

金奎堧 조선대학교 인문학연구소 1986 外國文化硏究 Vol.9 No.1

Irivng Howe는 하디의 마지막 소설 Jude the Obscure를 “Hardy's most distinctly modern work"라고 말했다. 그 이유는 이 소설이 근대소설의 주된 특징으로서 주인공들의 심리적 갈등과 플롯의 치밀한 구성의 관점에서 다양한 요소들을 지니고 있기 때문이다. 그러나 당시 이 소설이 출판되었을 때 많은 비평가들은 결혼문제와는 관계없이 어려운 처지에 얽매어 있는 사람들에게 동정은 고사하고 오히려 결혼의 제도에 적개심을 보여주었다고 비난하면서 이 소설에 대한 비윤리성을 지적했다. 특히 William Walsham How 주교는 이 소설에 대해 극단적 견해를 피력하였는데 이는 지나친 편견과 독단이 개재하였다고 할지라도 이 소설이 빅토리아 시대의 사회에 던져준 충격이 얼마나 지대했던가를 짐작할 수 있다. 그러나 정작 하디가 이 소설에서 추구하려고 의도했던 것은 그 시대의 사회적 소산인 가장 상징적인 관습과 가혹한 사회상을 폭로하려는데 있었다.

D.H.Lawrence의 생명주의(Ⅰ)

황규식 釜山大學校 1985 人文論叢 Vol.27 No.1

D. H. Lawrence is called a vitalist since he has an intense belief in the life-force. For Lawrence, the ultimate end of a human being is to be 'the whole man alive'. He thinks that it is necessary for a man to return to the spontaneous life-flow. Lawrence looks upon the sexual relationship between male and female as the strongest life-force, and, in that relationship he intends to renew, revive the dead life with in flesh. His main interest is always the relationship between man and woman, and he thinks it is one of the greatest relationships. In this relationship, Lawrence strives to overcome his complexes, the barriers he hates, for example, destructive forms of love-oedipal, spiritual and unbalanced-possessive. Furthermore he wishes to succeed in sustaining. and fulfilling his self and ideal. He represents such things in his marvelous novels, through the relationship between the main characters: for example, through Paul, Mrs. Morel, Miriam, and Clara in Sons and towers; and through Tom, Lydia, Anna. William. Ursula, and Anton in The Rainbow; and through Birkin, Her-mione. Ursula, Gertrude, and Cudrun in Women in love. Lawrence shows, in these relationships, that merltality, or spirituality is opposed to the completion of the vital, spontaneous, whole-alive man, and only direct contact of flesh, or blood-intimacy is true and real. Lawrence searches for the harmoneous, balanced whole organism. and tries to uniet the spiritual split and achieve the whole man alive. To do so, he emphasizes that the modern men should restore the dynamic intimate communication with nature, or the cosmos which is the great resource of vitality. In the above novels, the various kinds of communication are seen between male, or female characters and flowers, moon, or beasts whether these are satisfactory, or unsatisfactory. Strangely Lawrence represents the kind of love, or communication between man and woman, and between characters and nature as specific rituals, especially religious rituals. These are all based on Lawrernce's particular vitalism.

과학 영재의 세포 설명에 나타난 글쓰기 특성 분석

이혜정,심규철 韓國英才學會 2012 영재교육연구 Vol.22 No.1

The purpose of this study was to analyse characteristics of explanatory writing of scientifically gifted students who participated in gifted educational programs. Considering aspect of content of their explanations about cell, many of them explained the common characteristics of animal and plant cells, but a few of them did cellular characteristics of one kind of animal and plant. Some gifted students regarded cell membrane function as that of cell wall, and had a misconception that the cell was the smallest unit to consist human body. In terms of the structure of explanation, most of them didn't know the structural characteristics of explanatory writing. Finally, more than 50% of them had written using various ways to explain cell such as classifying, comparing, contrasting and exemplifying. Especially, all biologically gifted students had creatively explained drawing a picture. It was findings that the explanatory writing could be used as the instrument to evaluate knowledges of gifted students and suggested the elements of writing to teach scientific explanatory writing. 본 연구의 목적은 중학교 과학 영재 프로그램에 참여하는 학생들의 설명하는 글쓰기에 나타난 특성을 분석하는 것이다. 중학교 과학 영재들의 세포에 대한 설명을 분석한 결과, 내용적 측면에서 다수의 학생들이 동물 세포와 식물 세포의 공통적인 특징과 구별되는 특징을 설명하고 있었다. 그러나, 일부 과학 영재 학생은 동물 세포와 식물 세포 중 한 가지 세포의 특성만을 설명하거나, 세포막과 세포벽의 기능을 같게 보거나, 세포는 우리 몸을 이루고 있는 가장 작은 단위라는 등 세포에 대한 오개념을 갖고 있는 것으로 나타났다. 구조적 측면에서는 대부분의 과학 영재 학생들이 설명문의 체재를 명확히 알지 못한 채 설명하는 글쓰기를 완성하였다. 마지막으로 표현 방법을 분석한 결과, 50% 이상의 학생들이 분류, 비교, 대조, 예시 등의 다양한 방법을 이용하여 설명하는 글쓰기를 작성한 것으로 나타났다. 특히, 모든 영재 학생들이 그림을 이용한 설명 방법을 사용하였는데, 기존의 연구 결과에서 나타나지 않은 독창적인 것임을 알 수 있다. 본 연구의 결과는 과학 영재 학생들의 지식 평가 도구로 설명하는 글쓰기가 활용될 수 있다는 가능성을 제안할 뿐만 아니라, 설명하는 글쓰기를 지도할 때 활용할 수 있는 글쓰기 요소에 대한 교육적 시사점을 제공한다.

박민화,심규철,김현섭 공주대학교 과학교육연구소 2004 과학교육연구 Vol.35 No.-

본 연구는 중학교 생물 교과의 관찰 및 실험 수업에 Vee diagram을 사용했을 때 학생들의 학업성취도와 탐구능력의 변화를 알아보기 위하여 수행되었다. 연구대상은 평택시에 소재하고 있는 중학교 2학년 학생들로서 실험 집단은 1개 반의 31명(남학생:15명, 여학생:16명), 통제 집단은 1개 반의 33명(남학생:17명, 여학생:16명)이었다. 2000년 5월에서 6월 사이의 약 1개월간 실험 집단에 Vee Diagram을 적용하였으며 통제 집단은 전통적 실험수업을 실시하였다. 두 집단에 대해 사전 사후에 Vee Diagram 사용수업에 대한 인식을 설문조사 하였다. 결과 분석은 SPSSWIN 통계 프로그램을 사용하여 실험 집단과 통제 집단의 사전점수를 공변인으로 하는 공변량 분석을 하였다. 그 결과는 다음과 같다. 1. 학업성취도에서 실험 집단의 평균이 높게 측정되었으나 통계적으로 유의미한 효과는 없었다. 그러나 남녀 학생별 통계에서는 실험 집단 여학생의 학업성취도가 통제 집단에 비해 유의미한 효과가 있는 것으로 나타났다(p=0.044). 또한 두 집단을 수준별로 분석한 결과, 상위 30%에 해당하는 집단간에 유의미한 효과가 있는 것으로 나타났다(p=0.001). 2. 탐구능력 분석결과 두 집단 모두 사전 점수에 비해 성취도가 높아졌으나 집단 간 그리고 남녀 학생들간에 유의미한 차이는 나타나지 않았다. 다만 탐구영역별 분석에서 추리영역에서만 남학생들간에 유의미한 차이를 보였다(p=0.031). 3. Vee Diagram 사용 수업에 대한 실험 집단 학생들의 인식 조사에서 학생들은 Vee Diagram을 전통적인 실험수업 비해 흥미 있어 했으며, 사용 효과를 긍정적으로 인식하고 선호하는 경향을 보였다. The objectives of this study are to investigate the change of students' degree of accomplishment and scientific inquiry aptitude in applying Vee Diagram to the instruction of observation and experiment for graders of middle school. Two classes of second-grade of a middle school located in Pyongtaek city were selected as subjects. Experimental group class(31members; 15 boys, 16 girls) were instructed with Vee Diagram and the control group(33members 17 boys, 16 girls) were instructed with traditional method without Vee Diagram from May to June, 2000. Scientific achievement tests and scientific inquiry aptitude tests were administrated to those two groups before and after the instruction. Also after instruction, the experimental group were asked to answer a questionnaire about using the Vee Diagram in class. SPSSWIN statistic program was used to analyze the result and pre-test scores of experimental group and control group were used as covariates. The results of this study were as follows: 1. In the accomplishment test, the experimental group's average score was higher than that of the control group, but it was not statistically meaningful. However, girl students' accomplishment score in experimental group was meaningfully higher than that of control group(p=0.044). In addition, the analysis result of the upper 30% from each group revealed that the Vee Diagram is significantly effective. 2. In the analysis of scientific inquiry aptitude, both experimental and control group showed higher achievement than the previous analysis. However, no meaningful difference was revealed between the two groups, and between the boy and girl students. Only in the deduction area, the lower level of scientific inquiry field, meaningful differences were found between boy students. 3. Students in experimental group showed high interest and preference using Vee Diagram in class and students attitude to Vee Diagram was positive.

남승은,이규호 한국공업화학회 2002 공업화학 Vol.13 No.3

팔라디움(Pd)계 막들은 수소에 대한 선택투과도가 매우 높아서 고온의 혼합 기체 중에서 고순도 수소기체의 분리에 효과적으로 이용되고 있으며 탈수소 반응 등과 연계되어 많은 연구가 이루어져왔다. 순수한 팔라디움 금속 막의 경우 수소를 투과하면 수소농도에 따라 α 상 이외에 β 상이 형성되어 격자 평창에 의한 뒤틀림 현상이 발생하여 부스러지기 쉬우며 이를 보완하기 위해 니켈, 구리, 은 등 다른 금속과의 합금이 반드시 요구된다. 또한 높은 수소투과 속도와 기계적 강도를 함께 유지하기 위해 복합막 형태의 팔라디움 막이 제조되며 복합막 제조시 박막의 핀홀을 최소화하고 장기적 안정성을 유지하는 것이 매우 중요한 문제이다. 이러한 팔라디움 막을 막반응기에 활용함으로써 탈수소 반응이나 수증기 개질 반응 등의 반응효율을 크게 높일 수 있다. 본고에서는 팔라디움 막의 구조 및 수소와 다른 기체투과 메카니즘, 여러 팔라디움 복합막 제조 방법 및 이에 따른 특성 그리고 이들의 응용분야에 대해 살펴보고자 한다. Palladium(Pd) and palladium alloy membranes, which are well-known nonporous membranes with high perm-slectivity of hydrogen, have been used to separate hydrogen of high purity from vatious gas mixtures. The study of these membrane systems as hydrogen separation membranes and membrane reactors has been rather extensive for the past several decades. Pd alloys with other metals such as nickel, copper and silver are preferred over pure Pd, since pure Pd is subject to the α-β phase transformation due to the adsorption of hydrogen, which changes the atom spacing in the metal lattice and becomes brittle after repeated cycles of hydrogen sorption and desorption. For high flux of hydrogen permeation together with mechanical stability, Pd membranes have been mostly composite type structure with thin coating layer over a memchanically strong porous supporting layer. Minimization of pin holes and maintenance of long term stability of thin coating layer are very important factors in the preparation of composit membranes. The reaction effeciency of de-hydrogenation and water vapor reforming reaction was improve by the membrane reactors made with these palladium membranes. In this paper the structure of palladium membranes, the transport mechanism of hydrogen and gases, the preparation and characteristics of various composite palladium membranes and their applications will be discussed.

This study was designed to investigate the effect of dietary quetcetin on the levels of quercetin, α-tocopherol and total cholesterol in plasma and tissues of young chicks, Flavonoids are present in plants in their glycoside foam and consist mainly of flavonols, anthocyanidins, flavones, catechins and flavanones. Quercetin belongs to flavonols, a widely distributed class of natural substances and it is a strong antioxidant. It has been used for treatment of tumor inflamation allergy, arteriosderosis and prevention of major diseases including cardio vascular disease, stroke and cancer. Experiment was conducted using ISA Brown male chicks of one day old. Chicks were divided into the two dietary treatments in groups 1 and 2(group 1: practical diets supplemented with or without 200 ppm quercetin group 2: purified diets with or without 200 ppm quercetin). They were find the test diets for 21 days. Measurements were made far feed intake, body weight gain feed efficiency, weight of liver, plasma levels of quercetin, α-tocopherol and total cholesterol as well as levels of total lipids, total cholesterol of various tissues were measured. Analytical method using high-performance liquid chromatography(HPLC) was examined for the determination of dietary quercetin in blood, liver, thigh and breast tissues of young chicks. Levels of α-tocopherol in plasma and thigh muscle were also measured by HPLC. The results indicate that there was not change of feed intake, body weight gain and liver weight in young chicks maintained on purified tree diet when compared to fed practical type diet. Dietary quercetin was not transported or accumulated into the plasma and the tissues, while total cholesterol level decreased only in dietary groups added with 200ppm quercetin. The consumption of practical type diets reduced α-tocopherol status, especially levels of α-tocopheml were increased in plasma and thigh muscle on fed purified diets containing quercetin.

연순화,서봉국,박유인,이규호 한국화학공학회 2001 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.39 No.6

중공사막 접촉기를 기존의 흡수장치에 흡수기로 도입하여 구축한 hybrid 시스템을 이용하여 이산화탄소의 분리·회수에 관한 연구를 수행하였다. 분리효율이 우수한 중공사막 접촉기를 개발하기 위해 다양한 구조적 특성을 가지는 PVDF, PTFE 및 PP 중공사막을 이용하여 혼합 기체 및 흡수제 유량 등의 운전조건에 따른 이산화탄소 제거효율 특성을 조사하였다. 그 결과 중공사막 접촉기가 기존의 충진 흡수탑에 비해 큰 기-액간의 접촉면적으로 인해 분리효율이 높았으며, 그 중에서도 PVDF 중공사 막이 안정된 기-액간의 계면을 유지함으로서 다른 중공사막에 비해 우수한 분리효율을 나타내었다. 또한, 흡수제의 종류(H_2O, K_2CO_3, MEA)에 따른 흡수성능을 조사하고, CO_2-MEA계에서 각 중공사막에 대한 물질전달 특성을 비교하였다. 이산화탄소 분리효율, 경제성, 물질전달 특성 등을 고려하면, MEA를 흡수제로 사용한 경우, PVDF 중공사막이 막 접촉기로서 가장 적합할 것으로 기대된다. Membrane contactor-stripper hybrid process was used to recover CO_2 from the flue gas. Porous PTFE, PVDF, PP hollow fiber modules were used as the membrane contactor. The CO_2 was removed by the porous polymeric hollow fiber membrane contactor using H_2O, K_2CO_3 or monoethanolamine(MEA) solution as the absorbent. Then, the CO_2 was recovered from the absorbent by the thermal stripping tower with steam. The membrane contactor increased the gas-liquid contactor area and mass transfer coefficient, and thus the hybrid process showed a higher CO_2 removal efficiency than the conventional absorption tower. PVDF module with smaller pore size showed the most stable gas-liquid interface and the highest removal efficiency among the hollow fiber membrane contactor modules. gas
