쑥 분말 사료를 암돼지 및 거세돈에 첨가하여 그 수준에 따라 0%(T1, 암돼지, T2; 거세돈)와 1.5%(T3; 암돼지, T4, 거세돈)로 각 구별 45두씩 배치, 42일간 급여하여 생산된 돈육의 육질특성은 다음과 같다. 도체중량과 등지방두께는 73가 가장 낮았으며, 도체등급에서는 처리구간 유의차가 없었다(P>0.05). 쑥 분말 급여시 암돼지간(T1과 T3)에서는 조회분, 거세돈간(T2와 T4)에는 조지방 및 조회분 함량이 유의적으로 증가하였다(P<0.05). pH는 저장기간에 증가함에 따라 모든 처리구에서 감소하였으며, 쑥 분말 급여 처리구(T3와 T4)에서다소 높은 pH값을 나타내었다 드립감량은 처리구간에 일정한㎏/㎠경향을 나타내지 않았지만 저장기간이 경과함에 따라 높아졌다. 전단가(shear force, ㎏/㎠)는 T1을 제외한 모든 처리구에서 저장기간이 길어짐에 따라 감소하였다. 명도와 적색도는T3가 T1 보다 다소 높은 수치를 보였으나, 거세돈간(T2와 T4)에서는 오히려 낫게 나타났다. 저장기간이 증가함에 따라 TBARS와 VBN값은 공히 유의적으로 증가하였으며(P<0.05),쑥 분말 급여 처리구(T3 및 T4)에서 유의적으로 더 높게 나타났다(P<0.05). 지방산 분석결과, 포화지방산(saturated fatty acids)은 대조구에 비해 쑥 분말 첨가수준 증가에 따라 포화지방산은 높아지고 상대적으로 불포화지방산(unsaturated fatty acids)은 낮아지는 경향이 있었으나 유의차는 없고, 콜레스테롤의 경우에도 동일하게 유의적인 차이가 없었다. 전체적인 기호도는 신선육 및 조리육 공히 처리구가 낮은 점수를 얻었다. 향후 쑥 분말 급여에 대한 보다 많은 연구가 진행되어야 할 것으로 판단된다. This study was carried out to investigate the feeding effects of mugwort powder on meat quality characteristics for 42 days. The results obtained were as follows; Carcass weight(㎏) and backfat thickness(㎜) of T3 showed the lowest compared with other treatments. Grade scores were not significantly differ among the all treatments. In the proximate composition, crude ash content was higher(P<0.05) in the T3 than that of T1, while, crude fat and crude ash contents in T4 were higher(P<0.05) than those of T2. pH values were tended to low as storage period extended, in particular, those values slightly higher in the T3 and T4. Drip loss(%) was tended to increase during storage. Shear force(㎏/㎠) in all samples showed the decreased during the storage, except for Ti. L^(*) and a^(*) of T3 were slightly higher than those of T1, while, T4 was lower than T3. TBARS and VBN of all samples were significantly increased(P<0.05) as storage period extended, those values significantly higher(P<0.05) in the T3 and T4. There were no differences in saturated fatty acids, unsaturated fatty acids and cholesterol of pork meat between control(T1 and T2) and treatments(T3 and T4). The sensory score of pork samples fed with mugwort power were lower than that of control(T1 and T2) in both fresh and cooked meat. Further studied are needs on the pigs fed with mugwort powder.

Thomas Hardy 의 The Return of the Native에 나타난 Plots에 관한 硏究

金會珍 서울市立大學校 1985 論文集 Vol.19 No.-

The investigator's purpose of this thesis is to survey Hardy's pantheism through his plots in The Return of the Native, and find out the real truth of his dual theme. First of all, the writer's discussion is placed upon how nature, love, and chance act as plots against Hardy's characters. Of course, Hardy's pessimistic literature is a tragic one in which man fights against the inconsistency of Fate, 'Life offer-to deny.' Further investigation is extended to his philosophy, that is, his dual theme. According to Cockshut, Hardy has two contrasted temperamental traits: one is the sense of Plato's myth of the cave, and the other the sense of intense sympathy. In addition, Two features of his many-sided personality appear dominant: the sense of dignity and the sense of awe. Here, Hardy forms a sense of timelessness, as if man were tiny and faint against the grandeur and strangeness of a university. It is Hardy's pantheism and that is why his pessimism is formed. Lois Deacon says Hardy's pessimism is rendered strong 표 possibly incestuous love affair which Hardy had in his youth. Anyway, Hardy's theme is a combination of pessimism and determinism which is his dual theme. Briefly, this hypothesis may be applied to Hardy's literature. One is a deterministic theme in which we have to cope with Fate, 'Life offers-to deny.' and the other a fatalistic theme in which Fate is more religiously interpreted as an arbitrary power, a personal force like our own. Unlike contemporary writers, Hardy neither slanders nor disregards man's fraily, man's ambitions and woman's vanities, but he pleads. for, and loves, them all the more for that reason. Hardy's art is, in a sense, to create a type of human being, beautiful, noile and good. Hereby his dual theme combined in his works enables us to experience an emotional catharsis. Finally, the investigator adds that Desmond MacCarthy, speaking of Hany, says that Hardy's art is to dignify sorrow and disaster.

Calcium 및 Potassium의 심실근 수축작용에 대한 pH의 영향

김진회,배진선 충남대학교 의과대학 지역사회의학연구소 1984 충남의대잡지 Vol.11 No.1

Calcium ions have the important roles in the various processes in muscle contraction. Especially extracellular calcium as a source of calcium for contraction is decisive in cardiac muscle contraction because slow calcium inward current during depolarization of sarcolemma determines the calcium concentration in sarcoplasm. It is well known that hydrogen ion has the negative inotropic effect on cardiac muscle. Although the precise mechanism of hydrogen ion on cardiac contractility is uncertain, its effect on cardiac contractility is closely related to the action of calcium. The potassium ion also has a negative inotropic effect and its mechanism on cardiac contractility has not been established. Furthermore, the contractility is not known. The author intended to investigate the effects of concurrent changes in pH and calcium concentration, pH and potassium concentration on ventricular contactility. For these purpose, combination of each changes either in pH 8. 4, 7. 4 and 6. 4, i. e. 1 unit deviation from normal pH, with the calcium concentration of 1, 2, and 4 mM/L, or potassium concentration of 0. 5, 2, and 6 mM/L was chosen for ventricular perfusion. Turtle heart was selected for experiments and Langendorf's preparation for ventricular perfusion was used. The perfusate was Tris buffered Ringer containing with different electrolyte concentration according to each group. Tension and max. dT/dt as parameters of contractility were recorded by means of physiograph^R and its accessories. The results are summarized as follows;

메타인지적 지식과 작동기억이 메타인지적 규제 요구 과제의 성취에 미치는 영향

진화봉,이순아,김회수 한국교육정보미디어학회 2003 교육정보미디어연구 Vol.9 No.3

본 연구는 자기주도적 학습 능력의 핵심요소로 강조되는 메타인지가 작동기억의 중앙집행장치와 어떤 관계에 있는지 경험적 연구를 통해 밝히고자 하였다. 이를 위해 초등학생을 대상으로 세 개의 실험집단과 한 개의 비교집단을 구성하여, 메타인지적 지식과 작동기억이 메타인지적 규제 요구 과제의 성취도에 어떤 영향을 주는지 검토하였다. 실험 결과, 메타인지적 지식 수준이 높은 피험자는 낮은 피험자보다 메타인지적 규제를 요구하는 과제에서 더 높은 성취도를 나타냈다. 작동기억 용량에 따른 메타인지적 규제 요구 과제 성취도에 미치는 효과분석에서는 중앙집행장치와 언어적 작동기억을 제외한 시· 공간적 작동기억이 성취도에 영향을 미치는 것으로 나타났다. 그러나 시 · 공간적 작동기억 검사도구의 신뢰도가 높지 않았기 때문에 이 문제에 대한 결론을 확정하기 위해서는 추가적인 반복실험이 필요하다. 작동기억을 억제했을 때의 메타인지적 규제 요구 과제 성취도는 예측했던 대로 중앙집행장치 억제집단이 비교집단에 비해 유의미하게 낮고, 네 집단 중에서도 가장 낮은 것으로 나타났다. 이 결과는 메타인지적 규제 요구 과제가 중앙집행장치의 많은 인지적 자원을 필요로 하기 때문에 중앙집행장치 용량의 상하에 따른 성취도는 차이가 나타나지 않지만, 중앙집행장치를 억제하면 성취도는 크게 떨어지는 것으로 해석된다. 본 연구결과는 메타인지적 규제의 기능을 작동기억의 중앙집행장치가 담당하며, 메타인지적 규제능력이 높은 학습자는 자기주도적 학습에서 성공할 가능성이 높다는 것을 시사한다. 따라서 자기주도적 학습을 메타인지적 규제의 관점에서 접근하는 연구는 작동기억의 중앙집행장치를 고려해야 보다 설명력 있는 결과를 얻을 수 있을 것이다. This study was to examine the relationship between two components of metacognition and working memory that were considered as critical constructs to have influence on self-directed learning. The subjects were 140 sixth graders. They were randomly assigned to the three experimental groups and the control. Three experimental groups were given tasks requiring metacognitive regulation and concurrent working memory suppression tasks. The control group performed only the task requiring metacognitive regulation. The results of this study were as follows: The subjects with high metacognitive knowledge got higher achievement in the task requiring metacognitive regulation than the low metacognitive knowledge group. Visuo-spatial working memory span affected task performance requiring metacognitive regulation. However, because of low reliability of visuo-spatial span test additional experiments are necessary to confirm the results. As expected, the central executive suppression group showed significantly lower performance of metacognitive regulation tasks than the control group. Also the other groups got the lowest achievement. The findings suggested that the central executive would play the role of metacognitive regulation and the students with high metacognitive regulation skills would be successful in self-directed learning. It is desired that the study regarding the relationship between self-directed learning and metacognitive regulation skills consider the students' central executive capacity.

The quality of pork meat was determined as following treatments. The meat samples were obtained from pigs which had been fed finishing pig diets containing 2% perillar seed oil in beef tallow(T1), 250ppm vitamin E in T1(T2), 2% squid oil substituted of beef tallow(T3), 250ppm vitamin E in T3(T4). During storage period, meat color L^*, b^* value, fat color b^* value and drip loss were increased. The extraction amount of total protein and water holding capacity were increased until 14 days after then were decrease. The extraction amount of salt soluble protein and fat color L^* value were decreased and sarcomere length were decrease in T2 as well. T1 was higher than T2 in the extraction amount of total protein and its of T4 was higher than T3. The extraction amount of salt soluble protein of the T2 and T4 was higher than that of T1 and T3. The drip loss and the a^* value of meat color were lower in vitamin treated one than non treated one. On water holding capacity. T1 was higher than T2 and T3 was lower than T4. The L^* value of fat in vitamin treated ones was shown higher than that of non treated ones on day 1, however, it and the b^* value of the meat were low on day 28.

Thomas Hardy의 The Mayor of Casterbridge에 관한 연구

金會珍 서울市立大學校 1994 論文集 Vol.28 No.-

This paper is intended as an investigation of human ambivalence and Henchard's psychoanalysis, that is, his tragedy founded on the basis of ambivalence, and Hardy's view of fate. Thomas Hardy's tragic literature can accomodate a world of contrasting elements, It is the result of his attitude towards life which was one of "Life offers-to deny". Most of his works consist of the contrasting realities of tradition and modernism. His novels compared to the pastoral ones can be applicable to the former and his technique to the latter. The dual aspect of his novels can be replaced with realism and fantasy. They are found in the descriptions of Norcombe Hill in Far from the Madding Crowd, Egdon Heath in The Return of the Native and Casterbridge in The Mayor of Casterbridge. Hardy's view of fate can be taken as another example. We see that under the transition period between an old and new world his modernism is a reflection of his ambivalence. These two contrasting elements are presented as the main sources of his ambivalent literature. In The Mayor of Casterbridge Henchard's dual personality is revealed through his character and action, and the character and any given situation. To Henchard's tragedy Hardy applied Novalis' aphorism, "Character is Fate".

Thomas Hardy의 Far from the Madding Crowd에 관한 硏究 (Bathsheba의 유순화)

金會珍 서울市立大學校 1992 論文集 Vol.26 No.-

There is a great deal of complexity about Thomas Hardy's literature, for the two contrasting factors exist in his skill of laying out the literary material. But in his works it can be found that those contrasting factors are presented as the main sources of his ambivalent literature. The purpose of this paper is to find Bathsheba's taming in Far from the Madding Crowd and to define it as a Bildungsroman. Most of Hardy's world of literature is a tragedy caused by want of harmony between the two contrasting factors. But his earlier work, Far from the Madding Crowd ends in a happy ending. And there Bathsheba's taming is accomplished by the balance between realism and fantasy. The taming is on the same level with a hero's Building in his character and environment emphasized in most of the English Bi-ldungsromans. Here I came to the conclusion that Far from the Madding Crowd, unlike his later works, is transformed into a kind of Bildungsroman.

Thomas Hardy의 傳記에 나타난 OPEN QUESTION 硏究

金會珍 서울市立大學校 1988 論文集 Vol.22 No.-

After I studied Thomas Hardy from his character, domestic environment , education , vocational choice, love affair, marriage, and the like, it was given as a conclusion that his mental characteristics is 'Open Question.' Because of his mother's excessive affection, Hardy was frequently seized with a sort of shuddering to see that the outside world did not protect him. As the result, he rather wanted not to be a man but to remain a body. The lateness of development in virility also meant a tremendous lot to him because it was closely related to his wish of not becoming a fully grown man. It contained a sense of his fear of human absurdity, infinite time and vast space. His delayed virility and immaurity led him to remain a juvenile till twentyfive as he jokingly once side himself. According to his mentality, Hardy's feeling of lack of resolution may result from his delayed virility. He seemed to feel that when the actual world is disorderly, it rejects right judgement and decisions based on the judgement. The very lack of determination barred him from accomplishing his ultimate goals in the actual world. The moment anything is realized, his fear of incompletion leads him to be doubtful of its atainment. From this feeling of insecurity arose Hardy's denial of completion throughout life. With the sort of ambivalent approach to life, his mentality is charcterized by an open question. It may be said to be the basis of his "All romances end at marriage ", and "Love lives on propinquity, but dies of contact." In conclusion, Thomas Hardy has an open-ended type of mind in which he cannot come to a clear conclusion on anything. If his literature is the result of his ambivalent attitude towards life which is one of "Life offers -to deny", Hardy's literary ambivalence appears through the open question that exists in his subjective personality and in his skill of laying out the literary material.

과학 문제해결 과정을 활용한 초등 과학 수행평가 도구의 개발과 적용

최회정,임채성,김은진 부산교육대학교 과학교육연구소 2003 科學敎育硏究 Vol.28 No.-

In this study, the performance assessment tools using processes of solving problems in science were developed and applied to instruction, then their effects were analyzed both quantitatively and qualitatively. The results of the research can be summarized as follows: First, among the performance assessment tools developed in the study, the students' response formats were shown to be a useful method to understand collectively the processes and products of learning, and the students' appreciation toward it was also found to be positive. Second, in science instruction which proceeded through each step of science problem solving the science attitudes of the experimental group, although not statistically significant, showed more improvement than comparison one. Among the categories of science attitudes, 'attitudes toward science subject and the unit or topic studied' showed statistically significant improvement, which is interpreted as results of making harmony of preexisting students' interests with difficulty levels of tasks. Third, for overall several science process skills, there were no significant improvement. However, the subskills of inferring, data interpretation, and drawing conclusion were found to be increased significantly, which might be due to the frequency and depth of use of these skills in real instruction. Fourth, for aspect of the understanding of science knowledge and applying of it, there were statistically significant increase. That is, it was interpreted, through active participation in learning task across the whole range of performance of problem solving, that the abilities to applying science knowledge to the given problems were significantly increased.
