鋼板接着에 의한 鐵筋콘크리트보의 耐力 및 變形에 관한 實驗的 硏究

張華均,任七淳 관동대학교 1996 關大論文集 Vol.24 No.1

The purpose of this study is to provide the basic data for behavior of steel plate repaired reinforced concrete beams. The parameters were the thickness of steel plates. The concrete beams repaired with bonded epoxy and steel plate. The test show that the steel plate is very effective and predictable for strength damaged beams. The results show that the plate is the very important factor of strength and deformation in the damaged beams. In addition, the ultimate strength and deformation of steel plate repaired beams slightly more increased than the original beams.

120 holstein cows that were raised in Taegu and Kyungjoo area were investigated for studying the occurrence and treatment of infertility for the last 10 months, from April 1965 to February 1966. The results were as follows: 1. Among the 120 holstein cows 20 cows (16.7%) were infertile. Including a case of habitual abortion there were 12 cases of ovarian cyst, 3 of freemartin, 2 of endometritis, 1 of ovarian tumor and 1 of ovarian hypoplasia. The cows that had ovarian cysts were over than 63% of the infertile cows. 2. The most cows that affected with ovarian cyst were 4 years in age. 3. If the ovarian cyst cases are diagnosed and treated early enough they can be cured by manual rupture alone. 4. So far there is no occurrence of such infectious diseases as brucellosis, trichomoniasis, and vibriosis that induce infertility and abortion in dairy cows in Korea.

To evaluate the health status of lead workers in telecommunication industry, author studied 369 male workers working in a telecommunication industry. Study variables chosen were blood zinc protoporphyrin(ZPP), hemoglobin, serum glutamic oxalacetic transaminase(SGOT), serum glutamic oxalacetic transaminase(SGPT), γ-glutamyltrans-peptidase(GGT) and hepatitis B virus antigen and antibody. Personal data such as smoking and drinking habit, work duration were also collected. 15 lead related symptom questionnaires were provided to all lead workers and filled up by themselves and reconfirmed by physician. The results were obtained as follow; 327 workers(89%) among 369 workers were healthy and 42(11%) workers abnormal health state. 9 workers were disease state among 42 workers those who were abnormal health state. The most frequent disease was liver disease(52.4%), and next was hypertension(26.2%) and then anemia(9.5%), hyperlipidemia(4.8%) and pulmonary tuberculosis(4.8%) in order of frequency. There was no case of lead intoxication. The mean of blood ZPP concentration of study subjects was 14.4±6.9㎍/㎗ and maximum blood ZPP concentration was 48.0㎍/㎗. The means of GOT, GPT and GGT were 29.4±10.0unit/L, 19.7±14.4unit/L and 38.7±31.5unit/L, respectively. The prevalence rate of hepatitis B virus antigen was 6.8% and the one of hepatitis B virus antibody was 43.6%. The symptoms with high prevalence rate above 40% were six; 'loss of appetite', 'frequent numbness of fingers or feet', 'feeling tired or fatigue generally', 'becoming nervous or sensitive to not important things', 'feel dizziness when standing up', and 'feel sleepy frequently'. The prevalence rate of symptoms were increased by the increase of age. The prevalence rate of symptoms were higher in smoking group and drinking group than non-smoking group and non-drinking group, respectively.

The purpose of this study is to provide the basic data for behavior of steel plate-Repaired reinforced concrete beams. R.C beam is severely damaged by the total loading That the beam is repaired into the cracks of beams by epoxy injection method. This study illustate the effectiveness of severe damage in the beam. As a result, the ultimate strength of steel plate-repaired beams was slightly more Increased than the original beams.

사진을 활용한 시 창작 교육의 가능성

장화심,유성호 한국교원대학교교육연구원 2006 敎員敎育 Vol.22 No.3

창작은 더 이상 전문가들만의 것이 아니라 학습 과정에 있는 창작 주체 즉 학습 작가가 수행하는 문학적 글쓰기의 과정과 결과를 포함해야 하며, 따라서 '창작 교육'은 전문적인 작가를 배출하는 것을 목적으로 하는 것이 아니라 학습자의 문학적인 창작의 욕구를 자연스럽게 분출하여 생산 하도록 해야 한다. 따라서 시 창작 교육에서도 쓰는 경험을 제공하고 표현 과정을 중시해야 한다. 그래서 시 창작 교육은 단순한 감정 표현만이 아니라 인식의 차원에서 이루어지는 세상 읽기 교육이 되어야 하며, 경험이 부족한 학생들에게 인식의 폭을 넓히고 세상 읽기가 가능하도록 해야 한다. 이때 다양한 매체를 활용하면 효과가 배가된다. 여기서 사진의 매체적 특성은 매우 시사적인 가능성을 준다고 할 수 있다. 요컨대 사진을 활용한 교수 학습 활동은 사진 텍스트 읽기와 시 창작을 결합시키는 일이 될 것이다. 사진 안에는 내 삶을 돌아보게 만드는 남의 삶이 담겨 있다. 사진을 보고 학습자 자신의 사고를 글로 표현하는 과정에서 삶과 세계를 이해하고 주위 대상에 관심을 갖게 되며, 대상의 의미 해석을 통해 자신의 세계관을 확대하고 바람직한 세계관을 형성할 수 있다. 즉 간접 체험을 통해 인생과 삶에 대한 폭넓은 이해를 쌓고 나아가 자신의 삶을 되돌아보고 미래의 행동 지침으로 삼게 만들 수 있는 것이다. 또 사진을 보고 시를 창작하는 활동은 '읽기'와 '쓰기', '이해'와 '표현'이라는 상반된 것처럼 생각되었던 국어 교육의 내용을 결합하는 통합적 교육 효과를 얻을 수 있을 것이다. 또 인쇄 매체에 한정된 기존의 '읽기' 개념을 더 확장하여 문화 읽기로 나아가며, 작지만 매체의 변화를 고려한 국어 수업이 될 수 있을 것이다. Literature education needs to contribute to the fostering of a self-directed and active person. The crux of developing a self-directed and active ego-formation can be reached by encouraging students to engage in creative writing. However, literature education has been focused on how the literary works should be understood and appreciated. Literature education is introduced in the 7th national curriculum as an attempt to realize the ultimate goal of literature education, but has not been carried out well in the classrooms of individual schools. The part of' Literature reception and creative writing' includes' creative reconstruction of a literary work' and' creative writing of literature', in which the art of creative writing through' imitation' and' revision' is presented in the content organizations in the area of literature in the high school curriculum. In order to overcome this limitation of creative writing without any teaching method, a variety of attempts have been carried out. Among them, there are a great many of creative writing teaching methods through the formal elements, such as metaphor and rhythm, and techniques of expression. But, it is writing materials, not poetic expression that counts in the creative writing of poetry. Researches on mind-map, brainstorming, and free association as methods to make writing materials rich have been conducted, but it's difficult to draw pedagogical implications from the result of these researches for teaching creative writing to students with limited experience and knowledge. The purpose of this study is to present and propose a method of literature education that can engage the students in creative writing of poetry along with literature appreciation. However, this study shows a few limitations: not dealing with all the processes and methods for students' idea-making in a creative writing class, not analyzing the quantitative data showing the substantial improvement level of the students, and restricting them within the qualitative analysis of concrete situations of teaching of idea-making through the interaction between the teacher and the students.

장영조,서화일 한국기술교육대학교 2000 論文集 Vol.7 No.1

ABSTRACT This paper represents an FPGA implementation on USB Keyboard controller. USB is a serial interface to PC with 12Mbps full speed and applications for the peripheral devices are growing very widely. The architecture is designed with high modularity to devise various applications of USB. USB keyboard is classified to HID device. The design method for HID class is shown. Complex device containing mouse and ACPI function is also implemented by means of HID report to the same USB device. The keyboard controller is designed using Verilog HDL and simulated its functionality and performance. The architecture is implemented using an Altera 10KA100 FPGA and its evaluation board. The functionality is tested with direct connection to PC host and confirmed by USB compliance test program.

Alcohol이 마우스 소뇌의 조롱박신경원의 미세구조에 미치는 영향

장병준,윤화중,박창현 건국대학교 1996 學術誌 Vol.40 No.2

Effects of acute exposure to alcohol on fine structures of cerebellar Purkinje cells were investigated with electron microscope. ICR mice were injected orally by 18ml/kg b.w. of ethanol, and 30 minutes,2 hours, 6 hours, 24 hours, 3 days, 7 days after administration, mite were sacrificed with perfusion fixation. Specimens of each group were obtained by routine electron microscopic tissue preparation and were observed with transmission electron microscope. Dilatation of cisternae of rough endoplasmic reticulum, multiplication and cisternal dilatation of smooth endoplasmic reticulum, morphologic changes and cisternal dilatation of Golgi complex, swelling of mitochondria, increase of lysosome were prominent findings in the groups of 30 minutes and 2 hours after alcohol administration. These findings were getting recovered with the lapse of time. The territorial regions of astrocytes were prominently extended, and the synaptic vesicles of auto-somatic synapses were reduced in all experimental groups. These findings were also recovered gradually with the lapse of time, but these observations even in the group of 7 days after alcohol administration were not completely similar to that of control group.
