박홍석,이정섭,황성혜,김창현 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.5

연구목적 : 본 연구에서는 정신분열병의 병태생리에 뇌량이 관여하는지 확인하기 위해 초발 및 만성 정신분열병 환자, 대조군의 뇌량의 영역을 측정하였다. 방 법 : 국립의료원에 입원한 23명의 정신분열병 환자(남자 15명, 여자 8명)와 단순 두통 또는 어지럼증을 호소하여 내원한 23명의 외래환자를 대조군으로 하여 뇌자기공명영상을 얻었으며, 남자는 26명, 여자는 20명 이었다. 환자군중 초발군은 13명, 만성군은 10명이었다. 정중시상평면에서 뇌량을 7개 영역으로 구분하여 NIH Image 1.60프로그램으로 분석하였으며, 정중시상평면의 대뇌면적도 구하였다. 이렇게 구한 각 뇌량척도들은 t-test를 이용하여 대조군과 비교하였으며, 성별에 따른 차이는 ANOVA를 이용하였으며, 이후 대뇌면적을 공변량으로 하여 ANCOVA를 시행하였다. 또한 초발군과 만성환자군, 대조군의 비교는 나이와 대뇌면적을 공변량으로하여 MANCOVA를 시행하였다. 결 과 : 환자군과 대조군 사이의 총뇌량의 평균면적과 각 7부분의 평균면적을 비교한 결과 환자군이 제 3, 제 6 뇌량영역을 제외하곤 대조군에 비해 평균면적이 작은 것으로 나왔지만 통계적 유의성은 없었다. 성별에 따라 비교한 결과 통계적 유의성은 관찰되지 않았지만 남자환자는 대조군에 비해 작고, 여자환자의 경우에는 큰 것으로 확인됐다. 초발과 만성환자군으로 나누어 대조군과 비교해 본 결과, 통계적 유의성은 없었으나 초발환자군이 만성환자군에 비해 모든 뇌량척도가 작았고, 만성환자군은 대조군보다 총뇌량의 평균면적이 컸으나 초발군은 대조군 보다 작았다. 결 론 : 본 연구의 결과 정신분열병 환자에서 유의한 뇌량의 형태적 이상을 확인하지는 못했지만 이전 연구들에서도 다양한 결과들을 보고하고 있으며, 이는 정신분열병이 생물학적 및 임상적으로 각기 다른 표현형을 가지고 있다는 가설로 설명할 수 있다. Objectives : This study was performed to determine whether the corpus callosum is involved in pathophysiology of schizophrenia and measured corpus callosal areas of first episode, chronic schizophrenic patients and controls. Methods : We obtained the brain magnetic resonance imaging of 23 schizophrenic inpatients(15 males, 8 females) and 23 controls(11 males, 12 females) with simple headache or dizziness. Among the schizophrenic group, first episode patients were 13, chronic patients were 10. In mid-sagittal plane, the corpus callosum was divided into 7 areas and the cerebral area was measured. This data was analyzed with NIH image 1.60 software. We compared the corpus callosal areas of schizophrenics with controls by t-test and by ANOVA according to sex. Thereafter, ANCOVA was performed with mid-sagittal cerebral area as covariant. Comparison of first episode, chronic schizophrenics and controls was carried out by MANCOVA that was adjusted with age and mid-sagittal cerebra area. Results : The schizophrenics, compared with controls, had smaller corpus callosal areas except for the 3rd, 6th callosal area, but statistical significance was absent. According to sex, male schizophrenics had insignificantly smaller total callosal areas than male controls and female schizophrenics had larger ones. In comparison of first episode, chronic schizophrenic patients and controls, first episode patients had smaller every corpus callosal areas than chronic ones, chronic ones had larger total callosal area than controls and first episode ones had smaller total area than controls, but statistical significances were absent also. Conclusion : Our study did not reveal the structural abnormality of corpus callosum in schizophrenic patients, but many controversial results have been reported in other studies. This inter-study inconsistency could be explained by the hypotheses of not only clinical but also biological different phenotypes within the schizophrenia.

초등 사회과 현장학습 실태분석

황홍섭,이상례 부산교육대학교 교육대학원 2001 논문집 Vol.3 No.-

The purpose of this study is to analyze a actual state of field-learning in elementary socal studies. Research was performed with teachers and students of the 4th grade who were divided by ward office. The recovery rate for teachers was 82% (41 of 50 teachers returned the questionnaire). The recovery rate for the students was 70.4% (317 of 450 students returned the questionnaire). The result of the analysis of the actual conditions of field-learning is the following : 1) Most of the teachers(92.7%) and students(83.9%) are aware that they need field-learning, but actual school conditions make them difficult owing to the lack of principals' and parents' awareness, lack of programs, problems of transportation, costs, and lack of cooperation among teachers. 2) Field-learning is usually performed by grade(75.6%), but teachers should have discretionary authority to carry out the field-learning by class, thus ensuring field-learning diversity, promptness, and seriousness. 3) Through this study, it was discovered that teachers are not aware of the importance of preliminary studies, and prepare only simple materials and a simple teaching plan before the field-learning. In addition, they avoid field-learnings because of the difficulties of preparing effective teaching materials. When they make teaching materials for the trip, they usually do it with students and use internet(39%) a little more than the text or guidance book(34.1%). 4) Teachers select the region for field-learning according to the curriculum(90.2%). Thus, we know that most teachers follow the curriculum closely. 5) According to this analysis of the actual conditions of regional field-learning, there is little difference in the needs of field-learning, the reason, frequency, or the methods. There is, however, some differences in preliminary studies, the method of study after the field-learning, and the experiences during the field-learning. It is reported students living in Eastern Busan city, experience more direct field-learning and make use of the Internet more than students of other wards. 6) The number of students that haven't experienced a variety of field-learnings is high, and they are in need of an organised program for field-learning. The field-learning that they experience is the following: cyber field-learning(25.6%), indirect field-learning(15.1%), role play(7.6%). It is suggested that direct field-learning is the best way of studying Busan and using the Internet is second. In conclusion, we should improve educational conditions for liberal field-learning. Teachers should be able to use discretionary time and special activity time freely, according to the 7th curriculum. But there should be approval from the principal before field-learning is conducted by class. Most importantly, teachers must have concern and desire for the field-learning. the main problem for teachers with regard to field-learning is the lack of programs for it. We need to develop organised programs.

心理學 理論과 外國語敎育

趙弘燮 서원대학교 교육연구소 1982 敎育發展 Vol.2 No.1

I have suggested the constrasting views of behaviorism and cognitivism and the teaching theory resulted from those both sides. The behavioristic view focused on publicly observable responses-those which can be objectively perceived, recorded, and measured. Their typical models were classical and operant conditioning, rote verbal learning, instrumental learning, and discrimination learning. Cognitive psychologists consider meaning, understanding, and knowing to be significant data for psychological study. They try to discover psychological principles of organization and functioning. By using a rationalistic approach, they have sought to discover underlying motivations and deeper structures of human behavior. The structuralism of linguistics, under the influence of behavioral psychology, prided itself in a rigorous application of the scientific principle of observable responses. The behaviorists consider all learning to be the establishment of habits as the result of reinforcement or reward. With repeated reinforcement a habit is established and the child continues to name this person or object. As he continues to imitate sounds aroud him more combinations are reinforce. As he acquires more syntactic and morphological variations he creates new combinations by generalization or analogy, sometimes making mistakes by producing analogies which are not permissible. By a trial-and -error process acceptable utterances are reinforced by comparison and approval. Unacceptable utterances are inhibited by lack of reward. He gradually learns to make finer and finer discriminations until be utterly learns to make finer and finer discriminations and his utterances approximate more closely the speech of the community in which he is growing up. Chomsky claimed that language itself can no longer be viewed in the old way based on the S-R theory. He claims that Skinner's analysis of verbal behavior is meaningless because his terminology is vague, subjective, and empty when applied to real-life behavior. We cannot simply say that language is the thing that is learned or innate for a language is such a mysterious phenomenon: language is not something that can be explained and described by clear-cut and neat mathematical rules. By observing children learning a language we can clearly see that they constantly putting much more efforts in their language learning than we have thought: i.e. children are learning a language, not that a language is innate to them. At the same time we cannot deny that the language is species specific and species uniform. Various experiments led by psychologists to teach animals a language shows that there is certainly a limitation: animals have their limits in language learning. By understanding of varied theoretical positions we can choose particular approaches, methods, and techniques for teaching FL. And unless that principled basis is not our own carefully and thoughtfully devised theory, we become slaves to one way of thinking, a puppet without self-control. Our task is to find those points of compromise between two poles of possibilities which will best fit a grobal theory of FL learning. Language is a human mystery and one of God's blessings.

황홍섭,김옥점 한국지리환경교육학회 2003 한국지리환경교육학회지 Vol.11 No.3

이 연구는 사회과 학습 방법을 개선하기 위해 시도되었으며, 이를 위해 학습자 중심의 효과적인 사회과 학습을 위한 백지도를 개발하고 개발된 백지도의 효과를 입증하기 위해 현장에서 활동 학습지내지 수행평가지로 활용해보았다. 사회과 학습을 위하여, 첫째 교과서 진도에 맞추어 보조 교과서 자료로 활용할 수 있고, 둘째 다양한 문제 유형으로 구성하여 아동들의 흥미를 유발시키며, 셋째 사회과에서 요구하는 사고력과 탐구력을 향상시키고, 넷째 기본 학습을 익히고 난 후 다른 지역에 관한 확산적인 사고를 요하는 문제를 제시하여 수준별 학습이 이루어질 수 있는 백지도를 개발하고 백지도 활용을 위한 교수·학습 지도안을 작성하였다. 개발된 백지도를 활용한 학습은 기존의 학습 방법에 의한 학습보다 사고력 신장이나 학습자들의 적극적인 학습 참여를 유도하는데 효과적이었다. This study tried to improve learning method of Social Studies. To do this the study developed a base map for effective learner - centered social studies learning and made use of a developed base map verifying the effect of the base map. A base map for learning Social Studies was constructed as follows : first, the map can be used as a supplement to the textbook. Second, the map can enhance the students’ interest when it is made in various patterns. Third, the map can help improve the thinking power and inquiry skills needed in Social Studies. Fourth, learning according to the students’ level can be done with a base map when the content of other areas and by presenting the problems need comprehensive thinking after the students’ initial study. This study indicates that learning using base map is more effective in enhancing thinking power and participates in the students learning.

생활세계의 관점에서 본 PIFF 광장의 문화 공간적 의미 이해와 사회과 교육

황홍섭,박길자 부산교육대학교 초등교육연구소 2002 초등교육연구 Vol.17 No.-

The PIFF (Pusan International Film Festival) Plaza located on the movies' street including the Gukdo, Pusan, Daeyeong, Jeil, and Academy theaters screening international movies in Nampo-dong. Since 1996, Pusan International Film Festival provides a good opportunity for visitors to see the film selections around the world and occasionally to see the open festival held with the world-famous movie stars and directors and a large audience. But, it is particularly for the people lives in pusan, because of being the important space where one signify cultural meaning, which is the fundamental basis of historical, spacial, and social life. This study is, from the point of view 'life world' whose peoples lives around there in the everyday, to explore what they signify PIFF Plaza, how people make sense of the cultural meaning. It si two approach to The Cultural Space meaning of PIFF Plaza that deal with the problem of meaning in terms of phenomenology. such as E. Hussurl, A. Schutz and interpretation of culture, such as C. Geertz, P. Ricoeur. And it research into the layers of meaning which may be considered construction is shared of cultural meaning by others in everyday life through experience and the symbolic medium of language as a result from interaction. Hussurl argued that life world is consisted of the horizon of time and space. He has also addressed that the common sense of every day of life is the basis and starting point for every scientific type of interpretation. A. Schutz demonstrated that it is 'world taken for granted', hence a finite 'the provinces of meaning', which is particularly important because of accepting immediately and without question the external world as it is. C. Geertz. from the perspective of interpretation of culture, gives us to the way of analysis PIFF Plaza' the meaning of the every day of life world as a text through signs, symbols, and language. The cultural space' meaning of PIFF Plaza formulated self-identity through the medium of International Film Festival for the peoples live in pusan. The signification system of PIFF Plaza is appearing the space of the every day of life as a underlying basis, the space of symbols as a organic solidarity, the space of dynamic as an endless changing, the space of festival as a fantastic reality. Theory of life world, the cultural space's meaning of PIFF Plaza in life world as the system of culture, gives to social studies education for a few meaningful implication. First, students will be understanding the every day of life world as the space is formulated self-identity, shared meaning and experience by others. Second, they may be learn to the life world as the meaning of culture in terms of historicity, spaciality, and sociality.
