송정호 忠南大學校 大學院 2006 국내석사

Poly(diacetylene) is one of the most noticeable polymers which are new conductive organic materials. It is attractive polymer material because of its two triple bonds. In this research, HDD was synthesized through symmetrical coupling whit propargyl alcohol, and then we obtained PHDD from photo polymerization by UV-lamp. The conductive polymer was analyzed using IR spectrum and DSC. We measured oxide electric potential and ionic potential using cyclic voltammogram method to get information about electronic properties of PHDD and UV/VIS spectrum for band gap. Each of oxide electric potential, ionic potential and band gap were calculated 1V, 5.4eV and 2.25eV. We attained the energy-bend diagram with a fullerene which is electron acceptor from those. At that time, it showed that a difference of HOMO and LUMO of PHDD and fullerene are 0.65eV and 1.35eV. Through this data it was confirmed that the photoexcited PHDDwas energetically favorable for transfering an electron to fullerene molecules. The formations of bilayer heterojunction and bulk heterojunction were fabricated by vacuum filtration, spin coating, and immersion method. Photovoltaic effect was observed in both bilayer and bulk structure and the former was observed to have higher efficiency. It seems that this result was caused by the poor solubility of the two materials and the low contact area with electrode. Device efficiency was raised in photovoltaic device including the larger content of fullerene. 디아세틸렌인 HDD를 symmetrical coupling하여 합성하였고, UV-lamp로 광중합 하여 PHDD를 얻었다. 제조된 전도성 고분자는 IR 스펙트럼, DSC를 이용하여 분석 하였다. PHDD의 전기적인 특성을 알아보기 위해 순환전압전류법을 이용하여 산화전위와 이온화 전위를 측정하였고, 밴드갭을 알기위해 UV/VIS 스펙트럼을 측정하였다. 산화전위는 1 V이고 이온화 전위는 5.4 eV, 밴드갭은 2.25 eV로 계산되었고, 이를 이용하여 전자받게 물질인 플러렌과의 에너지 다이어그램을 얻었으며, 조합하여 스핀 코팅, 침적, 진공증착 등의 방법으로 이층구조와 벌크구조, 다층구조의 광기전력전지를 제조 하였다. 처음 예상과는 다르게 전자 주게 물질과 전자받게 물질의 접촉 면적이 큰 벌크구조보다 이층구조에서 그 효율이 높게 측정되었다. 이는 두 물질의 낮은 가용성으로 인한 결과로 판단되어진다. 또한 첨가된 플러렌의 양이 많을수록 효율 면에서 약간 더 높은 특성을 나타내었으며, 벌크구조의 경우 monomer인 HDD를 녹여서 사용한 HB구조에서 polymer인 PHDD를 미세 분쇄하여 사용한 PB구조 보다 조금 더 높은 효율을 보였는데, 그 이유는 두 전도성 고분자 사이의 접촉 면적이 넓기 때문이라고 생각된다. 단 이 경우 코팅 후 중합이 어려우며 중합이 되지 않아 그 특성을 보이지 않는 경우도 있었다. 상용화된 태양전지에 비교해서 효율이 매우 낮지만, 앞으로 다양한 구조의 폴리디아세틸렌을 조사하고 더 나은 재료와 제조법을 찾는다면 더욱 향상된 효율을 얻을 것이라 기대된다.

논쟁형 협동 학습 전략을 적용한 논술 교육의 방법과 그 효과

송정호 계명대학교 교육대학원 2004 국내석사

본 연구는 3사교의 새 교육과정 실현을 위한 교육 방법으로 협동 학습을 선택하고, 그것을 교과목 <문장과 화법>의 ‘논술’ 부분 수업에서 논쟁형 협동 학습 전략이라는 형태로 적용해서 그 교육적 효과를 검증하는 데 목적이 있다. 즉 본 연구에서는 협동 학습 과정과 논술 과정의 효과적인 접목을 통해 학습자의 지적·정의적인 교육 효과를 향상시키고자 한다. 최근의 논술 교육에 대한 연구는 교사 활동을 중시하는 논술 교육에서 학생 활동을 중시하는 논술 교육으로 그 흐름이 변화하고 있으며, 이에 따른 논술 교육의 방법으로 학습자 주도의 활동 및 상호 작용을 중시하는 협동 학습이 강조되고 있다. 한편 기존의 3사교 교육의 전반적인 방법은 전통적 강의식 학습 형태였기 때문에 생도들은 자신의 의사를 능동적으로 표현해야 하는 논술에 대해 많은 어려움을 느끼고 있었다. 이것은 논술의 교육 방법으로 협동 학습의 필요성을 말해주는 것이다. 논술과 협동 학습은 그 이론적인 배경에서도 일치하는 바가 많다. 문제 해결 학습은 문제 해결의 결과보다는 최종적으로 그 결과에 도달하기까지의 과정을 중시하는 교육 이론이고, 논술문은 주어진 문제를 대한 종합적인 사고력을 전개하여 그 해결 방안을 논리적으로 서술하는 글쓰기의 유형이므로 둘은 서로 유사하다고 볼 수 있다. 이는 문제 해결 학습의 본래적인 목표 달성을 위한다면 논술 교육에서 논술의 문제-해결 구조를 효과적으로 교육할 수 있는 교수·학습 방법으로 협동 학습이 적용되어야 한다는 것을 시사해준다. 한편 구성주의는 교수·학습에서 학습 구성원들 간의 사회적 상호 작용을 중시하는 이론인데, 이러한 측면은 협동 학습의 그것과 일맥상통하는 것으로 그 의미가 크다고 할 수 있다. 즉 구성주의의 교육적 실현 방법이 바로 협동 학습이다. 협동 학습에 대한 선행 연구들은, 사회적인 상호 작용을 그 본질로 하는 구성주의 교육 방법인 협동 학습이 전통적인 강의식 학습에 비해 교육의 지적·정의적 효과가 높고, 특히 정의적 효과에 있어서는 더욱 우수하다는 것을 말해주고 있다. 본 연구자는 이와 같은 사항을 감안하여 3사교 교과목 <문장과 화법>에서 논술 부분의 수업 방법을 기존의 개별 및 경쟁 학습을 토대로 한 교사 중심의 전통적 강의식 학습에서 학습자 중심의 협동 학습으로 개선하였고, 이에 따라 교육 방법은 물론이고, <문장과 화법> 수업과 관련한 교육의 전반적인 사항을 수정 및 보완하였다. 물론 이것은 논술 수업에서의 논쟁형 협동 학습 전략의 개발 및 적용을 토대로 한 것이다. 여기서의 논쟁형 협동 학습 전략은 군과 관련된 찬·반이 명확한 시사 문제에 대한 해결 과정에서 학습자 상호 간의 논쟁 측면을 중시한 교수·학습 방법이자 논술 교육의 절차이고, 학습자가 주도하는 논술 수업 전 과정의 세부 진행 단계이라고 할 수 있다. 이 전략의 핵심적인 특징은 논술 수업 활동의 활성화를 위해 논쟁의 개념, 즉 협동을 전제로 하는 경쟁의 개념이 제시되고 있다는 점이다. 다시 말해 각각의 소집단은 소집단 자체에서는 협동을, 타 소집단과는 경쟁을 한다. 그런데 이러한 협동과 경쟁은 전체 토론에서 바람직한 합의점을 도출하기 위한 과정적인 절차일 뿐, 그 이상도 그 이하도 아니다. 이상의 내용을 토대로 논쟁형 협동 학습 전략의 교육적인 효과를 검증하기 위한 실제 실험을 본 연구자가 담당하고 있는 교과목 <문장과 화법> 논술 부분에서 실시하였다. 이를 위해 실험 집단의 절반은 기존의 전통적 강의식 학습 전략을 적용한 논술 수업을 실시하였고, 나머지 반은 논쟁형 협동 학습 전략을 적용한 논술 수업을 실시하였다. 그리고 2003학년도 1·2학기, 두 차례에 걸친 실험을 통해서 논쟁형 협동 학습 전략과 전통적 강의식 학습 전략의 효과를 비교하고 분석하였다. 그 결과, 논쟁형 협동 학습 전략을 적용한 논술 수업의 교육적 효과가 전통적 강의식 학습 전략을 적용한 논술 수업의 그것에 비해 지적·정의적 측면에서 모두 높다는 사실이 검증되었다. 특히 논쟁형 협동 학습 전략은 정의적 측면에서 탁월한 효과를 나타냈다. 이 연구 결과는 특히 사관학교 논술 교육의 실제에서 밝혀진 내용이기에 그 중요성과 가치가 더욱 크다고 할 수 있다. This research is intended to prove the educational effect resulted from selecting cooperative learning (CL) as the teaching method in order to realize new education courses at the Korea Third Military Academy (KTMA) and applying it to the essay writing class in 〈sentence and speech〉 course with disputative cooperative learning strategy (DCLS). That is, this research will be helpful to improve the effect of intelligent and affective education of students by combining the course of CL and essay writing course efficiently. The recent researches on essay instruction have been changed from focusing on teachers' activities to students' activities. Therefore, CL focusing on both student-centered activities and the reciprocal action is prevailing as the teaching method of essay writing. Meanwhile, this made it difficult for the cadets to write essays that require an active expression of their intention because the overall teaching methods at KTMA were the traditional lecture-centered learning on the basis of individual study. This is why CL is necessary in teaching essay writing. Essay writing and CL have many things in common concerning the theoretic background. Study on problem-solving is similar to essay writing. Problem-solving studies the educational theory that focuses on the process to reach the conclusion rather than the conclusion itself. Essay writing is a kind of logical writing method to solve the given problems by synthetic thinking capability. This is why achieving the original objective of a study on solving the problem requires CL, as the teaching and learning method, which is the efficient way to teach the structure of problem and solution in education of essay writing. Meanwhile, constructivism is a theory that makes great account of a social reciprocal action among studying members concerning teaching and learning, which is meaningful in corresponding with CL. That is to say, the way to realize constructivism in the educational aspect is CL. The previous researches in CL indicate that this teaching method of constructivism based on a social reciprocal action, has more intelligent and affective educational effect than traditional lecture-focused teaching and it is much better especially in affective effect. Considering the facts mentioned above, I have improved the teaching method of essay writing in the <sentence and speech> class of KTMA by changing the traditional lecture-focused instruction, which is teacher-centered based on the existing individuals and their competitive learning, to the student-centered instruction. Along with it, I have modified and supplemented not only the teaching method but overall educational aspects of the class, 〈sentence and speech〉. It is natural that it should be based on the development and application of DCLS in the essay writing class. DCLS is the teaching and learning method and the progress of teaching essay writing that focuses the dispute among the students in the process of solving the pros and cons with regard to the military. And it can be said to a detailed progress step among all the process of the student-centered essay writing class. The special feature of this strategy is to suggest the dispute conception, that is, the competitive conception based on cooperation, for making the essay class very active. In other words, the students cooperate with one another in small group, but each small group contends with the other groups. Such cooperation and competition is no more than the process or procedure of reaching a correct agreement. I conducted the actual test in my essay writing class, <sentence and speech> on the basis of the facts mentioned above as to prove the educational effect of DCLS. The existing traditional lecture-focused instruction was applied to the essay writing class for half of the test group and DCLS was applied to the other half. I compared the effect of DCLS with the strategy of a traditional lecture-focused instruction, and analyzed them through two tests in the first and second semester in 2003. The conclusion shows the essay writing class based on DCLS has more intelligent and affective educational effect than the one based on traditional lecture-focused teaching and DCLS is much better especially in affective effect. I am sure the conclusion of this research is very valuable and important because it resulted from the practical situation of essay writing instruction in a military academy.

The purpose of this study was put on the analysis of the types of motivation and the physical self-efficacy with regard to the gender difference, the participation period, and the participation frequency of the participants in sport for all swimming activity, and on the investigation into the correlation between them. To achieve the objective of this study, SPMS(Sport Participation Motivation Scale) developed for 303 participants in sport for all swim activity by Pelletier, Vallerand, Tuson & Briere(1995), a method of measurement which Jung, Yong-Gak has modified to fit in Korean culture, was used. Also, a method of measurement which Ryckman, Robbins, Thornton & Cantrell(1982) developed for the physical self-efficacy that Hong, Sun-Ok adapted was used. An average and a standard deviation were presented to explain the general features of the sample group. For the other related problems in this study, one-way analysis of variance, correlation analysis, and reliability analysis were applied. The followings are the results of this study. First, the gender difference in motivation for participating in the swim activity did not appear to be statistically significant. That is, it can be interpreted that both men and women take the health problems seriously. When it comes to the types of motivation to take part in the swim activity regarding the participation period, there was a significant difference in fun factor and condition factor. But there was no such a significant difference in amotivation factor. The group of people in the participation period from 10 to 20 years showed high marks on the fun factor and the condition factor. The people who participated in the swim activity for such a long time tended to feel enjoyment through it, and they tried to keep in shape by doing it. There was a significant difference among the groups in the fun factor, achievement factor, condition factor, and amotivation factor when considering the participating motivation in swim activity based on the participation frequency. The everyday group was the highest in the fun factor, achievement factor, and condition factor, but the lowest in the amotivation factor. There was a significant difference among the groups in the fun factor, condition factor, sociality factor, and amotivation factor when considering the participating motivation in swim activity based on the perceived level of exercise. The group of people who perceive themselves high-level are prone to pursue the enjoyment through the swim activity, and they also swim for keeping in shape and the purpose of sociality. Second, there was a considerable difference in perceived physical factor regarding the physical self-efficacy of the participants in the swim activity from the different genders. In other words, it is possible that we can say men showed a strong confidence about their body. The participants of the time period of 10 to 20 years in the participation period recorded the highest in the perceived physical factor when we look into their physical self-efficacy. The everyday group was the highest in the field of the perceived physical factor when we consider the physical self-efficacy of the participants in the swim activity in view of the participation frequency. The everyday group proved to have a strong confidence about their body. The participants of higher level group hit the top in the perceived physical factor taking into account of the physical self-efficacy of the participants in the swim activity with the perceived level of exercise. Third, thinking about the correlation between the participants of the sport for all swim activity and the physical self-efficacy, we can conclude that the perceived physical ability can be positively correlated to both the intrinsic motivations like fun factor, achievement factor and the extrinsic motivations such as condition factor, sociality factor, and external showing-off factor. However, there appeared to be statistically negative correlation between the perceived physical ability factor and the amotivation factor. Physical self-expressive confidence had significant positive correlation with fun factor and achievement factor which belong to the intrinsic motivation, and with condition factor, sociality factor, and health & stamina factor which are subcategories of extrinsic motivation. The subcategories of the extrinsic motivation like external showing-off factor, a motivation factor had statistically negative correlation with physical self-expressive confidence.

송정호 경희대학교 2010 국내석사

丹蔘이 뇌조직출혈에 따른 뇌부종에 미치는 영향을 관찰하기 위해서 흰쥐의 선조체 내에 콜라겐분해효소를 주사하여 뇌조직출혈과 뇌부종을 유발한 다음 丹蔘 물추출물을 3일간 경구투여하고, 뇌부종 비율과 MPO 양성반응의 호중성백혈구 침착의 변화를 관찰하였으며, iNOS 및 TNF-α 발현의 변화를 면역조직화학염색을 통해 관찰한 바 아래와 같은 결과를 얻었다. 1. 丹蔘은 뇌조직출혈에 의한 뇌부종의 증가를 유의하게 억제하였다. 2. 丹蔘은 뇌조직출혈 주변조직에서 MPO 양성반응 호중성백혈구 침착을 유의하게 억제하였다. 3. 丹蔘은 뇌조직출혈 주변조직에서 iNOS 발현 증가를 유의하게 억제하였다. 4. 丹蔘은 뇌조직출혈 주변조직에서 TNF-α 발현 증가를 유의하게 억제하였다. 이상의 결과로 보아, 丹蔘은 호중성백혈구 침착을 억제하고, iNOS 및 TNF-α 발현을 억제하는 기전에 의해 뇌조직 염증반응을 억제하며, 이러한 염증반응 억제효능에 의해 뇌부종을 감소시키는 것으로 판단된다. This study was performed in order to evaluate the effects of Salviae miltiorrhizae radix (SMR) water extract against brain edema formation in the intracerebral hemorrhage (ICH). ICH was induced by the stereotaxic intrastriatal injection of bacterial collagenase type IV (0.23 U/μl, 0.1 μl/min) in Sprague-Dawley rats. SMR was orally given once a day (500 mg/kg) for 3 days after ICH. The percentage of brain edema and myeloperoxidase (MPO)-positive neutrophils infiltration were examined. iNOS and TNF-α expressions were observed with immunohistochemistry. The results are as follows; 1. SMR significantly reduced the percentage of brain edema of the ICH-induced rat brain. 2. SMR significantly reduced MPO positive neutrophils infiltration in the peri-hematoma regions of the ICH-induced rat brain. 3. SMR significantly reduced iNOS positive cells in the peri-hematoma regions of the ICH-induced rat brain. 4. SMR significantly reduced TNF-α positive cells in the peri-hematoma regions of the ICH-induced rat brain. These results suggest that SMR plays a protective role against the brain edema formation in the ICH through suppression of inflammatory response.

火災被害 調査業務의 發展方案에 관한 硏究

Ⅰ. Introduction When a fire breaks out, it usually causes casualties as well as enormous financial damages. When a fire becomes a conflagration, it brings a chaos making an enormous impacts in our society. In order to prevent fires and minimize damages, it is very important to utilize the data on fire gathered on site. The data collected from investigations should include the details such as the type of fire and the extent of damages to inform the public. This could prevent similar types of fire and minimize the loss. Also, the data collected from investigations should be utilized when making policies and implementing laws related to fire prevention. However, due to many systematic as well as practical difficulties, investigations are not carried out properly. Investigations are conducted to examine the cause of the fire and the extent of damages caused by the fire. Recently, fire analysis and research division has been established in regional fire offices in an effort to increase the expertise in investigations. Because investigations have been conducted around examining the cause of a fire, this area has been well established. However, investigations of fire loss are often inaccurate due to lack of appropriate laws, experience in investigation, and standards in calculating fire loss. The estimate of fire loss calculated by fire offices are often in disagreement with the fire victims' estimate. Inaccurate investigation makes it hard for data to be used in preventing fire and taking safety measures. This study focuses on finding out the cause of low confidence in fire investigation and how it impedes building credibility in fire prevention effort in fire offices. The result shows that the biggest problem with fire investigations are that investigative procedures are not strongly enforced as they are prescribed under directives and not mandated by statute. My analysis also showed that a unrealistic standard used in calculating fire loss, lack of experience in investigation, and unpractical procedure of investigation leads to low confidence among general public with fire offices. In order to assess the level of confidence in fire investigations, I have conducted the survey among fire officials, fire victims and the general public. 61% of respondents, that is 70 people out of 115, showed that they have a low confidence and feel that investigation process require improvements. The survey showed that improvements are needed in following areas; establishing a standard in examining financial damages, utilizing equipment and the use of outside experts. The survey also revealed that fire officials do not follow a standardized process in conducting an investigation and often hastily file a report in order to meet the deadline. In most cases, financial loss was calculated based on an investigation conducted once. Based on the survey results which dealt with investigative work in fire offices, I have made following recommendations. Fire prevention and safety laws should be amended in order to include all matters related to investigations. Also, the standardized method of calculating financial damages should be implemented and the credibility of such a method should be increased. Fire officials in charge of an investigation should increase their expertise in their respective areas as well. Investigations should be conducted precisely and systematically despite unfavorable conditions. The data collected from investigations should include all important details as they may be used by fire victims in court as evidences. Also, any public announcement of investigation should focus on casualties and loss as it is often done in foreign countries.
