This study was performed to investigate elementary school teachers' perception and attitude about the School-Based Curriculum Development(SBCD). In order to attain this purpose: First, the character of the six curriculum revision and the background, meaning, and scope of SBCD were discussed on the basis of the related literature review. Second, elementary school teachers' perception and attitude about SBCD were analyzed. For the purpose of gathering the data, 5 elementary schools in Seoul were randomly selected and then the questionnaire about SBCD was distributed to the teachers of those schools. The subjects of the last analysis were 192 teachers. The main results of this study were as follows: 1) Only a part of the elementary schools implemented SBCD. Moreover, only a few teachers participated in SBCD. 2) Most of the teachers recognized necessity of SBCD, but almost half of teachers showed negative attitude toward the feasibility of SBCD. 3) Most of the teachers desired to modify and adapt centrally developed curricular and select among them rather than create new curricular. 4) Although teachers suggested that different people including teachers participate in SBCD, they responsed that teachers should play a leadership role in SBCD. 5) The main reasons that teachers showed negative attitude toward participation in SBCD was lack of time, professional knowledge and ability, and concern and recognition. On the basis of these results, the actual conditions and problems of SBCD and elementary school teachers' perception and attitude about SBCD were discussed. Finally, some suggestions were made for the activation of SBCD.

This study examined how research of teacher effectiveness has been conducted and how effective teachers has been defined and then what is an effecvtive teachers' characteristics? Effective teachers' characteristics and behaviors have demonstrated positive relationships with student' achievement in many studies reported in the educational literatures. Effective teachers' characteristics are seem most closely related to students' learning. Effective teachers helped their students learn more other teachers with similar students and seem to be more better and successful in producing learning among their students. Effective teachers have shared seven common characteristics(or attributes) and abilities which tended to influence student' learning. The followings are : 1) Effective teachers have enthusiastism. Teachers' enthusiam promotes learning by helping to motivate students. Enthusiastic teachers vary their voice, gestures and expressions. Enthusic behavior of the teacher may have been a by - product of either the teacher's euporior organization of the material or his greater tadk orientation. 2) Effective teachers have warmth and humor. Teachers' warmth and humor seem mostly to influence students' learning. Also, Trust is the pre-condition for relationship to be an effective interaction between the teacher and the student. Therefore Effective teachers have credibility and trustworthiness. Its create a relaxed, confortable, open and supportive environment where students trust the teacher to help them be successful in their learning. Humor can be planned. If Warmth and humor overemphasized, these are actually reduce classroom learning atmosphere and so they are best used natuarally and effectively. 3) Effective teachers have high expectations for success and encouring and supportive of students' learning. Effective teachers have positive teachers. They believe in their own ability and help every student learn to be successful. Effective teachers can be modifing teachers' expectation in order to apporiately reflect students' level of abilities. 4) Effective teachers have encouring and supportive of students and convey a sense of genuine respect for them. Encouragement and support are most important when students are relevant to begin new tasks or when they experience difficulty and frustration. 5) Effective teachers have businesslike or task-oriented demeanor. Businesslike teachers focus on promoting learning in a varities of ways. Instruction activities are deliberate and carefully planned to allow teacher to be concise, thorough and efficient. classroom activities are organized in order to help students research the desired goals. 6) Effective teachers have flexibility and adaptibility. They effectively adapt to changing classroom circumstances and have the ability to read what is happening in the classroom(ex. the level of student' understanding and problems with instruction). when the problems arise in the classroom, effective teachers must flex or adapt instruction to more effectively reach the established goals. 7) Effective teachers have lnowledgeable of their subject matters, pedagogy and students. Knowledge of ability is most useful when integrated with knowledge of pedagogy and knowledge of students. Effective teachers must have an ability to effectively use these three elements.

High selective and sensitive thick film type methane gas sensors were fabricated and their sensing characteristics for various hydrocarbon gases were investigated. Raw material, SnO_(2)/Au, prepared by coprecipitation was even grain size. SEM, TEM, BET and XRD analyses were carried out for investigation of surface morphology and crystalline structure. The thick film devices using the above materials exhibited high sensitivity to methane gas at the operating temperature of 400°C. The sensitivity of SnO_(2)/Au+Pd thick film devices to methane gas was higher than that to the other hydrocarbon gases such as iso-butane and propane. The optimal adding amounts of Au and Pd were 1wt.% and 3wt.%, respectively. The sensitivity, S, is defined as {(R_(A)-R_(G))/R_(A)}><100, which R_(A) and R_(G) are resistance in air and that in the gas ambient, respectively.

Total absolute detection efficiencies of a 7.62 cm(dia.) and 7.62 cm(height) cylindrical NaI(Tl) crystal have been calculated for 0.412 MeV r -rays from a source(point, circular disk, square and line type). In this calculation the linear energy-absorption coefficients based on Hubbell's data have been considered and then calculated total absolute detection efficiencies compared with those from Grosjean and Bossaert. Besides, the source axis-to-detector axis shift distance which, could give rise to about 0.05% deviation in the total absolute detection efficiencies has been calculated for a line-type source of 0.5 cm in its length when a source-to-detector distance is 5 cm. It is revealed that the total absolute detection efficiencies obtained in this study are considerably different from those of Grosjean and Bossaert. In addition it is found that the deviation induced due to an imperfect center of a line type source may be within 0.05% if the shifted discrepancy is no larger than 1.74mm.

大學의 敎授方法과 認知學習戰略

The purpose of this article is to inform about current trends in teaching and learning, to elaborate the context that shapes those trends, and to propose how those trends can be implemented in new settings. College instructors should focus their teaching not only on content but also on how to learn content in the contest of particular courses. Cognitive learning strategies is a plan for orchestrating cognitive resources, such as attention and long-term memory, to help achieve a learning goal. I believe that every college teacher has a professional obligation to formulate and articulate a rationale for his instructional world. To select or create strategies that will help students meet their learning goals, students must be aware of characteristics about themselves as learners, they must know about the characteristics of the tasks they are expected to perform, and they must know about different types of learning strategies. Instructors' decisions about how to teach, like students' decisions about how to learn, are the products of prior knowledge and executive control. Similarly, instructional strategies are most effective and efficient when instructors know about themselves as teachers, know about different instructional strategies. In practical implications of cognitive theories, the learner is at center stage. The instructor becomes a facilitator of learning, rather than one who delivers information. This perspective on learning contrasts sharply with models that imply that learners get the point as long as the instructor provides an appropriate stimulus. Cognitive psychology says that the learner plays a critical role in determining what he gets out of instruction. As college instructors, we are also participants in the conference(or stage), but we participate from the head of the table. To ensure a successful conference, we should encourage other participants to share the knowledge they bring with them, and we help them learn how to take as much material as possible away with them.

洪思澳,李香雨,鄭相允 成均館大學校 1983 論文集 Vol.33 No.-

This study was undertaken to investigate the effects of placenta on the toxicity of KC-400 in rabbits. Rabbits were treated with 800㎎ of KC-400 in 2㎖ olive oil via IP injection intermittently day after day for a week and were successively administered with 2㎖ of the placenta extracts via I. V. injection twice a day after day as well as with the placenta extracts with 50 ㎎ of vitamin C as well. The results obtained in this experiment were as follows: 1. When the experimental animals were treated with human placenta, there wasn't any alteration of the hematochemical indicators such as RBC, WBC, Hgb, Het, serum Cholesterol, s-GOT, s-GPT, serum Alkaline Phosphatase and Total lipids in serum. 2. According to the experiment of PCB poisoning, while s-C, s-GPT, s-ALP, and s-TL were increased, RBC, WBC, Hgb and Het were decreased during the experimental periods respectively. 3. The placenta extracts normalized the hematochemical indicators of the PCB poisoned animals after one day treated by the placenta extracts. 4. The combined treatment with the placenta extracts and vitamin C was the same effect as the single placenta treatment only; they were not significant in the t-test. 5. The placenta extracts inhibited the serum tyrosinase activity of the rabbits which was induced by PCB in vivo and in vitro respectively. By the combined treatment with the placenta extracts and vitamin C, the activity of tyrosinase was remarkably inhibited in comparison with the single treatment with the placenta alone.

As crops recently can be cultivated all the year in greenhouses, we need to improve the environment in which crops are able to grow in the summer. Therefore, in this study, we quantitatively got the cooling effects of 4 single span plastic greenhouses in the following ways : by spraying mist or sprinkler, or by opening the side window. and with those variables, we simultaneously did experiments at 4 greenhouses under equivalent conditions to reduce the temperature of the greenhouses in the summer. The results of the experiments are as following : 1) The temperatures of the greenhouses were effectively reduced by both spraying mist and sprinkler. 2) When the mist is intermittently sprayed. the indoor temperature has decreased by 4 degrees centigrade, meanwhile, in the greenhouse to make experiments using sprinkler, the temperature of that has been reduced by 2 degrees centigrade. Therefore, we can see the cooling effects of smaller mist in size as more effective than those of sprinkler. 3) When the greenhouse is naturally ventilated by opening the side window, we have to apply another cooling system because the indoor temperature is higher than the outdoor one.
