ABSTRACT A study on the Effects of Mathematical Daily Writing to Mathematical Attitude Son, Hui-Kyoeng Major In Mathematics Education Graduate School of Education Sungkyunkwan University The purpose of this research is to investigate whether the mathematical attitude of the students can change through their mathematical daily writing. In order to conduct this research, I surveyed 40 students who are at the first year of A high school in Ansan for 4 weeks. I let the class do mathematical daily writing and observed the difference before and after. I also investigated the response toward mathematics and the characteristics of the students' mathematical daily writing. The results of this research are as follows. First, the students showed positive response about mathematical daily writing. They were provided the chances of participating it and approaching mathematics more closely. Second, the marks of the mathematical daily writing by students were that it could help students to debate about solving problems, or it was used a tool of communicating. Also a kind of free writing brought about students' interest and it showed their various thoughts and opinions. Third, it was shown that the mathematical daily writing could have a positive effect on students' attitude toward mathematics. However, this study has been done for short term, so I couldn't observe the effectiveness on students' attitudes toward mathematics steadily. It is necessary that I continue instructing the students in daily writing for a longer period time for more accurate, detailed research.

갯기름나물 분말이 고지방-고콜레스테롤 식이를 급여한 흰쥐의 지질대사 및 항산화 활성에 미치는 영향
Recently known Peucedanum japonicum Thunb. is one of the medicinal plants that use the Saposhnikovia divaricata as a substitute for plants. It was beneficial effects for preventing a stroke, efficacy of detoxification and respiratory diseases. This study was carried out to investigate the effects of Peucedanum japonicum Thunb. powder on lipid metabolism of serum, liver and adipose tissue, and anti-obesity effect in rats fed a high-fat/high-cholesterol diet for 4 weeks. It was also conducted to investigate major chemical components analysises of Peucedanum japonicum Thunb. The results obtained were as follows; 1. This study was conducted to investigate the changes in physicochemical properties of Peucedanum japonicum Thunb. by blanching. After blanching treatment, the crude fat, crude ash and carbohydrate contents of Peucedanum japonicum Thunb. were increased, but the crude protein was decreased. The content of all detected free sugars were decreased by blanching, the content of total free sugar was decreased 14.8% compared with raw Peucedanum japonicum Thunb. after blanching. The total amino acid and essential amino acid contents of blanched Peucedanum japonicum Thunb. were decreased 10.75% and 15.22% than raw Peucedanum japonicum Thunb. The contents of total fatty acid was regardless of blanching. Total organic acid content decreased by 37.03% compared with raw Peucedanum japonicum Thunb. after blanching, and the reduction of acetic acid was the largest in organic acid. The content of vitamin A, E and C were decreased 20.20%, 8.23% and 35.59% after blanching. Total mineral content of blanched Peucedanum japonicum Thunb. were decreased 21.84% by blanching. Peucedanum japonicum Thunb. was contained nutrients composition of essential amino acid, vitamin C, minerals, but these were reduced by blanching. 2. This study was conducted to investigate the antioxidant effect of 80% ethanol extracts from Peucedanum japonicum Thunb. Total polyphenol contents of raw and blanching Peucedanum japonicum Thunb. ethanol extract were found to be 16.60 mg/g and 22.25 mg/g respectively. Also, total flavonoid contents of raw and blanching Peucedanum japonicum Thunb. ethanol extract were found to be 40.65 mg/g and 50.80 mg/g. The DPPH radical scavenging activity of raw and blanching Peucedanum japonicum Thunb. ethanol extract were found to be 87.86% and 87.91%. It was similar to the commercial antioxidant BHA and BHT. 3. This study investigated the effects of Peucedanum japonicum Thunb. powder on serum, liver and adipose tissue lipid metabolism and in rats fed high-fat/high-cholesterol diet for 4 weeks. Male Sprague-Dawley rats were assigned to 6 groups : Normal diet group (N), high-fat/high-cholesterol group (HFC), high-fat/high-cholesterol with 5% raw Peucedanum japonicum Thunb. powder(HFC-SPL), high-fat/high-cholesterol with 10% raw Peucedanum japonicum Thunb. powder(HFC-SPH), high-fat/high-cholesterol with 5% blanching Peucedanum japonicum Thunb. powder(HFC-SPL) and high-fat/high-cholesterolwith 10% blanching Peucedanum japonicum Thunb. powder(HFC-SPH). The body weight gain and FER were increased by a high-fat/high-cholesterol diet, but gradually decreased in the Peucedanum japonicum Thunb. powder fed groups compared with the HFC group. Food intake was no significantly different between the experimental groups. The liver and adipose tissue weights of HFC group were heavier than of N group, whereas those of groups administered Peucedanum japonicum Thunb. powder were gradually decreased. The serum ALT, AST and LDH activities were no significant difference between HFC group, but the serum ALP activity was significicantly decreased after Peucedanum japonicum Thunb. powder administration. The serum triglyceride, total cholesterol and LDL-cholesterol levels as well as the atherogenic index and cardiac risk factor tended to decrease in the groups fed Peucedanum japonicum Thunb. powder than the HFC group. The serum HDL-cholesterol level decreased in HFC group, but no significant difference in groups fed Peucedanum japonicum Thunb. powder. Levels of triglyceride in liver and epididymal tissue, the cholesterol level in epididymal tissue were lower in the groups fed Peucedanum japonicum Thunb. powder than the HFC group. The liver GSH level increased in the groups fed Peucedanum japonicum Thunb. powder than the HFC group. The liver TBARS content was significantly lower in the HFC-PRH group, HFC-PBH group than the HFC group. These results suggest that Peucedanum japonicum Thunb. powder may improve lipid metabolism of serum, liver and adipose tissue and prevent oxidative stress by stimulating antioxidative systems in rats fed a high fat-high cholesterol diet.

손희경 우석대학교 일반대학원 2017 국내석사
국내 대표적 팔경이자 명승 집경의 전형적 사례인 관동팔경의 형성과정에 주목하여, 문헌자료와 도상자료의 분석과 해석을 통해 관동명승에 대한 집경 및 팔경 형상화 및 정착시기를 탐색한 본 연구의결론은 다음과 같다. 고려시대부터 현대까지 오랜 시간 동안 생성·축적·확장과정을 거쳐온 관동팔경은 지역 안배를 고려한 관동 해안가의 대표적 명승으로정착되었다. ‘關東八景’이란 용어가 처음 발견되는 문헌인 이황의「答洪應吉」로 볼 때, 관동팔경은 이미 16세기 이전 당시 인들의 인식속에 정착되었을 것으로 추론된다. 『신증동국여지승람』을 비롯한지리지 분석 결과, 관동팔경 은 16세기 초․중반에 관동십경으로의확장 또한 이루어졌다. 최초의 관동팔경에 대한 집경은 신즙의「詠關東八景」에서 확인됨에 따라 관동팔경이라는 용어는 문학 분야에서는최소한 16세기 이전부터 존재하였으며 현재의 ‘팔경’ 세트의 관동팔경으로 정착된 시기는 늦어도 17세기 초반이라 추정된다. 관동 명승의출현빈도 분석 결과, 시문에 등장한 관동 명승은 관동팔경 경물에 대한 집중현상이 뚜렷하였다. 한편 회화 분야에서 오로지 관동팔경만을 모은 그림은 허필의 『關東八景圖屛』에서 최초로 확인된다. 실경산수화에서 표현된 관동팔경은 시문에서의 집경 양상과 유사한 경향을 보이지만 화제 출현률 순위는 시각적 결속력과 응집성이 더욱 강한 것으로 드러났다 이는 일정한 관념체계 상 특정한 의의를 지니고 제작된 회화 작품이 갖는 도상(圖像, icon)을 중요시하는 특성이 반영된 결과로 판단된다. 더불어조선 후기에서 근대에 들어 제작된 다수의 민화 형식의 《關東八景八幅屛風》은 관동팔경의 문화현상이 보편적 수용기에 접어들었음을 알리는 확실한 근거이다. 또한 조선후기 성행한 남승도놀이 등 명승유람놀이에 등장하는 강원도내 13개의 명승에는 관동팔경이 빠지지 않고 나타나고 있음을 볼 때 조선 말기 관동팔경은 놀이문화 속에서도 고하게 정착되었음을 확인할 수 있었다. 이와 같은 결과를 종합할때, 관동팔경의 인식은 15세기 전반 이전부터 있어 온 것으로 보이고,16세기 형상화 과정의 지속적 전개를 통해 17세기 완전한 정착이 이루어지며 18세기에 들어 관습화·보편화 된 것으로 추정된다.궁극적으로 관동팔경은 고려시대부터 별개의 경물로 명성을 얻은지역 명승이, 17세기 후반 구체적으로 형상화되었음을 알 수 있다. 관동 명승 그 중에 관동팔경은 오랜 기간 여러 사람의 탐승과 유람문화향유를 통해 오직 여덟 개의 최상의 명소만을 모으기 위한 절차탁마(切磋琢磨)의 과정을 거쳐 형성되고 배태된 지역 고유의 문화 경관임을 일깨워준다.

P. Hindemith의 『플루트와 피아노를 위한 소나타』 작품 분석 연구
Paul Hindemith(1885-1963) had activity engaged as a composer, a conductor, a theorist, an educator and one of the neoclassicism composer. His tendency in musical art has built up a fundamental system of harmonic form which is based on traditional growing composition and revitalized modernized classical form such as sonata, symphonies and concertos. Also, he had composed lots of practical musics for musical instruments. This paper researched and analyzed Sonata fur flote und Klavier(1936), written by Paul Hindemith. This is the first opus of use ten woodwinds and ten brasswind from 1936 to 1943. It was composed in 1920's, corrected in 1936 and published in 1937. This is my analyzed result. The exposition of the First movement has four structures of musical intervals. They are quite important elements and developed throughout each part. They are focused on a core tune. The upper music staff rule and the lower music staff rule are either progressing into chromatic scale and diatonic or are making opposit progression and retrogression. Not only Hemiola or a syncopation but regular rhythm are applied to the exposition. It is also modulated for similar progressing and it gives a rhythmical change between melodies and accompaniments. Continuing melodies are used for keeping the right composition and rhythm. Also, the first movement has Coda in sonata form. The theme shows rhythm changing, the spreading and reduction of note values, imitation technique and similar progressing. The Second movements is a brief sonata form like a rhythmical singing called Cantilena. The Third movement classified into Rondo form and Seond rotate section. All of melody materials generate from the First theme and shows the modulation anaphora changes. Marsch section is defined as the Four movement rather than Coda. Although there is clean and brief similar progressing and can be made as one section, it does make it an independent Movement. This movement is classified into non-counter point and mock counterpoint. Non counterpoint has continuing contra composition. Mock counterpoint expresses developed theme quite well and is classified overlapping and non-overlapping. It has 4 degree composition chord, 5 degree composition chord and non-4 degree composition chord and decide the composition lines by doing parallelism or opposite progressing. Hindemith had tried to compose music easy for modern audiences to understand. If players want to understand composition techniques and opus, Hindemith's work will help their perfect play of musical instrument.

2015 개정 초등 5학년 영어교과서의 게임 활동 분석
본 연구는 2015 개정 교육과정이 적용된 초등학교 5학년 영어교과서 총 5종 중 3종을 선정하여 선정된 교과서의 게임 활동을 분석 후 교과서 게임 활동의 문제점과 개선 방향을 제시하고자 한다. 게임의 목적, 동력, 조직형태, 승부요소, 자료, 언어기능의 6가지 기준에 따라 분석하여 아래와 같은 연구결과를 얻었다. 첫째, 게임 활동을 목적에 따라 분석한 결과, A교과서는 의사소통게임의 비율이 더 높게 나왔으나 B와 C교과서는 언어연습게임의 비율이 더 높게 나왔다. 2009 개정 교육과정이 적용된 A, B교과서를 유사한 기준으로 분석한 최혜란(2017)의 결과와 비교해보면, 의사소통게임의 비율이 증가한 것을 알 수 있다. 둘째, 게임의 동력에 따라 분석한 결과 '경쟁'요소가 50%를 넘는 비율을 차지하였다. '경쟁'요소가 가장 높은 교과서는 C교과서이고, 그다음이 B, A교과서 순서였다. 2009 개정 교육과정이 적용된 A, B교과서를 분석한 최혜란(2017)의 연구와 비교한 결과 '경쟁'요소의 비율이 10%이상 감소한 것을 볼 수 있다. 셋째, 승부요소에 따라 분석한 결과 행운에 의해 승패가 가려지는 게임이 더 많았다. 행운의 비율이 높은 교과서는 C, B, A교과서 순서였다. 학기별로 비교한 결과 1, 2학기의 비율이 비슷했지만 1학기에 행운에 의한 게임이 조금 더 많았다. 학생들의 학습 지식이 적은 1학기에 행운에 의한 승패가 결정되는 게임을 많이 제시하여 학습동기를 높일 수 있도록 한 것으로 보인다. 넷째, 조직 형태에 따라 분석한 결과, 개인 활동은 사라지고 교사나 친구와 상호작용하여 학습할 수 있게 구성되었다. 이는 2015 개정 교육과정에서 제시하는 공동체 역량과 그 하위요소인 대인관계 능력을 적극 반영한 것으로 보인다. 다섯째, 게임에서 활용하는 자료의 종류를 분석한 결과 교과서별로 순위가 다양하였다. A교과서는 기타, 카드, 도구 순이었고, B교과서는 카드, 그림, 기타, C교과서는 기타, 그림, 도구 순이었다. 여섯째, 언어기능에 따라 분석한 결과 듣기와 말하기 기능을 동시에 습득할 수 있는 게임이 전체의 50%나 되었다. 듣기+말하기의 비율이 높은 순서는 C, A, B교과서 순이었다. 분석 결과 나타난 문제점과 개선방안은 다음과 같다. 첫째, 게임의 목적이 편중되어 있다. A교과서의 경우 의사소통게임에, B와 C교과서의 경우 언어연습게임에 편중되어 있다. 따라서 추후 개선 시 게임의 목적이 편중되지 않도록 조정할 필요가 있다. 둘째, 승패가 없거나 경쟁/협동의 요소가 나타나지 않는 등 게임의 요건에 맞지 않는 게임이 있다. 게임의 요건에 맞지 않는 활동을 수정·보완하여 게임의 요소가 존재하도록 만든다면 학생들의 학습동기를 유발하는데 긍정적인 영향을 미칠 것이다. 셋째, 게임의 언어기능이 듣기+말하기에 치우쳐 있다. 2015 개정 교육과정에서 음성언어를 강조하고 있지만 50% 이상이 듣기+말하기 기능에 치중되어 있다는 것은 다소 개선할 필요가 있다고 보인다. 따라서 문자언어를 학습하기 위한 게임의 비중을 늘릴 필요가 있다. 마지막으로 본 연구는 2015 개정 교육과정이 적용된 5종의 검정교과서 중 3종만 분석하였으므로 일반화할 수 없기에 교과서별, 학년별 종합적으로 분석한 후속연구가 필요한 실정이다. We chose 3 textbooks among revised 5th grade elementary English textbook by the Education Law of 2015, and analyzed game activities by 6 references. First, by analyzing the purpose of game activities, textbook A contains communication game much more than code-control game for language training. But textbook B and C were opposite. Second, We analyzed the games: whether the games require competition of cooperation. All the textbooks require competition more than 50 percent. Third, we analyzed the games: students win the game by the luck of language ability. The proportion of luck and language ability was similar but victory by luck was a little bit more than language ability. Forth, by analyzing the game: the form of learners, group activity was most popular in all textbooks. It looks like that textbooks reflect the community capacity which the Education Laws of 2015 emphasize. Fifth, by analyzing the materials of the games, the results was various from textbook A to textbook C. Etc was most popular in textbook A and C. But textbook uses cards most. We analyzed the language skills used mostly in the games. The result was listening&Speaking was 50 percent. In sequence, in case of arranging the problem of game activity of textbook and remedies, it is as follows. First, the purpose of the game was lopsided. Textbook A was lopsided to communication game, textbook B and C was lopsided to code-control game. So, there is a need to adjust the purpose of game so that it is not biased. Second, there is a game that doesn't fit the qualification for the game. There is a need to change the term 'game' which doesn't fit for game to 'play' or modify the game. Third, there is a need to increase the proportion of written language. Finally, as this study analyzed only 3 textbooks among 5, it has difficulty in generalizing. If the follow-up studies which analyze and compare the games of textbooks which were revised 5th grade elementary English by the education Laws of 2015, it provides the good resources to English teachers.

조선 후기 中室型 정자의 건축특성에 관한 연구 : 경남 서부지역을 중심으로
Korean Jung-ja was erected in the scenic views from the precious Joseon Dynasty. In addition, natural and environmental factors such as lifestyle and culture can be seen the sentiment of the people of the era. However previous studies have had a lot of research in architectural approach still lacking in other state sectors. There was a number of studies around the Honam region in the field of architecture. In particular, The Joongsil type’s Jung-ja has been limited to review by the plane type that represents the locality of Honam region. Early on there were cultural exchanges between regions through the marriage of man and the political and social cohesion. In addition, it also influenced architectural culture. There are a large number of Joongsil Type’s Jung-ja in the western Gyeongnam its east side of regional distribution for the boundary Mt. Jiri, and It appeared in the survey that in many ways, such as location, flat format, structure, design showing that differences in Honam’s. The study specifically for viewing at the locality of a building in the center of the area and distinctive architectural elements distributed aims. In the presence and characteristics of the underlying architecture of the building plan through a comparison of how the Honam region and locality of the western Gyeongnam area explores whether being expressed, and affecting the setting of architectural and cultural forms of architecture to explore the culture and the elements.
