장정원 우석대학교 2016 국내석사

< ABSTRACT > Zhang, Jing Yuan Major of Chemical Engineering Dept. of Advanced Materials Engineering Graduate School of Woosuk University Monitoring of energy storage system(ESS) connected with photovoltaic under various operating conditions was carried out. Performance degradation of a battery in 20 kWh energy storage system was studied and energy saving of the ESS connected with 20 kW photovoltaic (PV) was monitored. PV-connected ESS saved 5~7% of energy consumption to that of 2012. As charge-discharge cycle increased, capacity decreased and the performance degradation was glaringly obvious after 40 cycle. And as charge and discharge rate increased, the performance degradation was more serious. After 50 charge-discharge cycles, a lot of contamination was deposited on the surface of anode and cathode electrodes, and the cathode side was more contaminated. Therefore in order to maintain the cell performance, it was more important to protect the degradation of the cathode side. 국문 초록 에너지 저장 시스템 운전조건에 따른 태양광 연계 모니터링 연구를 수행하였다. 20 kWh급 에너지저장 시스템의 배터리 성능감소를 평가하였고 20 kW의 태양광 발전시스템을 연결하여 에너지저장을 모니터링 하였다. 태양광과 연계된 에너지저장 시스템을 사용한 결과 2012년도의 에너지 사용량에 비해 5-7%의 에너지절감을 확인하였다. 충방전 싸이클이 증가할수록 용량이 감소하였고 40 싸이클 이후에는 성능감소가 현저하였다. 충방전 속도가 증가하면 성능저하는 더욱 크게 나타났다. 50 충방전 싸이클 이후에는 전극표면에 많은 불순물이 생성되었으며 셀의 성능을 유지하기 위해서는 cathode의 성능저하 방지가 중요함을 알 수 있었다.

장정원 嶺南大學校 大學院 2002 국내석사

기계 제작 및 건축 분야와 같이 많은 원자재를 사용하는 분야에서는 생산 단가를 줄이기 위한 노력을 해왔다. 생산 단가를 줄이기 위한 방법에는 두 가지가 있다. 첫 번째 방법으로는 못쓰고 버리는 원자재의 량을 최소화하는 것이고, 두 번째 방법으로는 재고량과 원자재의 시세를 감안하여 잘 사용하지 않는 원자재나 싼 원자재를 많이 사용하는 재고 문제를 고려한 방법이다. 지금까지는 이러한 분야에 대한 연구가 거의 없었으며, 최근에야 비로서 원자재의 량을 최소화하기 위하여 현장 경험을 바탕으로 한 휴리스틱한 방법을 이용한 연구가 이루어지고 있다. 그러나 휴리스틱한 방법은 최적의 배치를 하는데 많은 시간이 필요한 단점이 있으며 재고 문제를 고려하지 않았다. 본 논문에서는, 최소의 소요 시간으로 버려지는 원재의 량을 최소화하는 부재의 조합을 찾을 수 있으며, 여러 원재들 중에서 정해진 개수만 사용거나 또는 정해진 개수 이상을 사용해야하는 원재가 있는 재고 문제를 해결할 수 있는 1차원 최적 배치 유전 알고리즘을 제안하였다. We have made an effort to decrease the cost of productions in machinery or construction. There are two methods to decrease it. The first method is to minimize the origin material wasted and the second method is to consider the stock beams and the origin materials for the stock and the cost. there is not the study for this part until now and is the study using the huristic method based on their experiment in these days. However, it takes much times to do the first optimal arrangement in this method. In this paper, we can find the combination of the beam to minimize the quantity of origin material wasted, and propose the genetic algorithm for the first optimal arrangement to solve the stock problem that is the case of using the justified number of origin material or the case of using more than the justified number in many kind of origin material.

古代日本의 茶道와 佛敎文化 形成에 기여한 百濟文化

장정원 東國大學校 2016 국내석사

Korea and Japan have been exchanges since the 4th century B.C.. Residents of the ancient Korean Peninsula had introduced rice farming techniques and Iron Age civilization to Japanese people. So Japanese people closed the period of Jomon and opened the Yayoi era. Baekje, ancient Korean empire and Walt, ancient Japanese kingdom established officially diplomatic relations in 366. After Walt sent a delegation at Tagsun in Korea, the two countries began diplomatic relations. Walt needed advanced culture in order to create an ancient kingdom. Baekje demanded military aid to Walt against Goguryeo Empire and China. Because the interests of two countries coincided, they started diplomatic relations. Their diplomatic relations had been continued after the fall of Baekje in 660. After King Eyja gave in, a remained people of Baekje raised a revival movement. Because the allied Forces of Silla and Dang did not dominate perfectly Baekje. Baekje Revival Forces resisted the allied forces until 663 in August. Baekje Revival Forces was disbanded because of friction. Walt had six times supported Baekje Revival Forces for military 32,000 people and massive ordnance. Generally speaking, it was a difficult decision, it is easily to understand. Scholars have a variety of allegations about the reason of support. It was sure Baekje and Walt had had a strong relationship. It estimates Baekje people had been drunk tea in third or fourth century. We could not find a record of tea culture, but it was found Guesuho at the Baekje heritage site and, Dongjejan and Cheongdongjewan at the Royal Tomb of King Muryeong. These were used as a tea service. And there were fragments of pottery in The Architectural Layouts on Miruksa. This proves a tea culture of the Baekje Dynasty. Especially, in 1993 Gilt-bronze Incense Burner of Baekje had been discovered in Neungsan-ri, burial grounds. This is important artifacts that can be linked to the Baekje tea culture. Baekje immigrants moved to Japan and monk Gyoki, a descendant of Wangin built the temple and planted tea plant trees around the temple. It proves that Baekje people usally drank a tea. It is easy to find traces of Baekje immigrants at Nara and Osaka, Kyushu in Japan. There are Baekjewang-ginja and Dodaigi, the Great Buddha in Dodaigi, Kudaragi, Sairingi, Askabe-ginja, Sitannogi, Saidaigi etc. The sites were founded by the people of Baekje. Baekje Buddhist monks moved to Japan in sixth or seventh centuries, and did various activities in Japan. They introduced Buddhist civilization and Buddhist scriptures. They redefined Buddhism in Japan. The Baekje Dynasty ran a local governance, Damno. It is a unique system that can not look in ancient country. Baekje ruled Southeast Asia, mainland China and India, Philippines region, some parts of the Japanese archipelago through Damno. Baekje dispatched royal family and the nobility, the priests to Japan. Personally, migrant groups is also nobility and the priests. Tea lover was royal family and the nobility, the priests at that time. They drank tea every day routine. They drank tea in Japan. It was a natural thing to do. Culture is transmitted by man. It takes a lot of time to learn culture. The Japanese people imitated Baekje immigrants' life style. Tea culture gradually spreaded in Japan. Considering Baekje and Walt diplomatic ties and their cultural exchange, signs remaining of the Baekje people in Japan, the factors of dissemination of culture, It is persuasive the posibility is that Baekje influenced in the development of traditional Japanese tea culture. 韓国と日本は紀元前4世紀から今まで交流をしている。韓半島の居住者が稲作技術と鉄器文明を日本に伝来したことによって、縄文時代を終えて日本列島を弥生時代に導いた。韓国と日本が公式的に外交関係を結んだのは366年だ。倭が卓淳に使者を送ったことによって百済と倭の外交関係が成立した。倭は古代国家の形成に向けて先進文物が必要で、百済は高句麗と中国に対抗するために軍事的な支援が必要し、両国の利害関係が合致し、国交正常化が行われた。 百済と倭の外交関係は、百済が滅亡した660年以降も継続された。義慈王が降伏した後に百済では、百済復興運動が起きた。新羅と唐連合軍が百済を完全に掌握できず、百済王室の降伏を受けて出したからである。百済復興軍は663年8月まで抵抗する復興軍内の軋轢が発生するなどさまざまな原因のために解散することとなった。倭は滅亡した国家に船舶を動員して軍事3万2000人と莫大な規模の軍需物資を6回にわたって支援した。一般的な外交関係で見ると容易に理解することが困難な決断だ。学者たちは倭の軍事支援の理由について様々な主張をしているが、百済と倭は常識的に理解しがたいほど緊密な関係を保っていたとみなされている。 百済は3、4世紀にすでに茶を飲用していたと推定される。文献上明確な記録はないが、百済遺跡地であるソウル風納土城古墳群で、中国の六朝(りくちょう)時代の鶏の頭の飾りギェスホ(鷄首壺)と中国から輸入した蓮の葉模様青磁椀、武寧王陵で出土されたドンジェジャン(銅製盞)とチョンドンジェワン(靑銅製碗)、弥勒寺址にある寺跡で百済時代の陶磁器の破片と受け皿などが出土し、百済の時、茶飲用文化が一般化したことが類推することができる。特に1993年陵山里にある古墳で発掘された百済金銅大香炉は百済のお茶文化と関連付けられる重要な遺物だ。日本に移住した百済の移住民や王の子孫である行基僧侶などが寺刹と日本の主要遺跡地の周辺に茶の木を植えたという記録を『東大寺要録』4巻で見ることができる。この記録は3、4世紀に韓半島の飮茶說と百済茶文化の日本伝授説を確定する重要な資料である。このため、韓国でお茶を飲み始めた時期を3、4世紀に繰り上げなければならないとみなされている。 日本の奈良地方と大阪、九州地域で百済人の痕跡を簡単に検索することができる。百済王神社、東大寺と東大寺大仏、日本5ヵ所に存在する、百済寺、王仁氏族を祀っている、西琳寺、百済の王族である昆支王に仕える飛鳥戶神社、王仁博士の墓、百済の建築技術を象徴する四天王寺、百済人が創建した西大寺など数え切れないほど多い。この遺跡地は、百済人が建設したり、百済人を称えるため建立された。 6、7世紀、百済の僧侶たちが倭国に渡り、多くの活動をした。彼らは仏教文化と教理を紹介して旺盛な布教活動と仏教の講義、研究活動を通じて倭国の仏教文化を確立させた。倭国で活動した代表的な僧侶は觀勒、法明、覺從、義覺、弘濟、道寧、道藏、僧旻、惠隣、惠至、惠妙、多常などだ。 百済は古代国家の中で見られない地方統治制度である擔魯制を運営した。擔魯を通じて中国大陸はもちろん、遠く東南アジア地域とインド、フィリピン地域まで統治しており、日本列島の一部地域も百済の統治管轄に属した。 百済が倭に派遣した階層は王族や貴族、僧侶などが主流を成している。個人的に移住した集団も貴族や僧侶が大半である。そして、百済時代に茶を飲んだ階層も王族や貴族、僧侶たちであり、互いに一致する。茶道が日常で行われていたため倭に移住した百済人も日本でお茶を飲んだというのは自然なことだった。文化は人によって伝播されて、憧れていた文化を学習するのに相当な時間がかかる点を考慮すれば、百済の移住民が日本でお茶を飲む姿を見て、日本の現地人たちも模倣していたのと思われる。日本古書から茶の効能を認めたという記録があちこちで発見され、日本で茶道文化は次第に広がったことだと考えられる。 百済と倭の外交関係、文物交流、日本に残っている百済人の痕跡、文化の伝播の要因などを考えるとき、百済が古代日本茶道文化形成に影響を及ぼしたという可能性は十分説得力があるとみなされる。

한국예술가곡에 나타난 한국적인 요소들에 대한 고찰 : 나운영, 김진균을 중심으로

張正元 全南大學校 大學院 2005 국내석사

한국예술가곡은 1920년 홍난파의 <봉숭아>로부터 시작된다. 그후 한국가곡은 더욱 발전하여, 1960년대로 접어들면서 한국예술가곡만의 톡특한 요소들이 두드러지게 나타나게 시작하였다. 본 논문에서는 60년대에 활발하게 활동하였던 나운영과 김진균의 가곡을 살펴보고자 한다. 먼저 나운영의 작품세계를 살펴보고, 그의 작품을 통해 작품 속에 나타난 한국적인 요소들을 찾아보고자 한다. 나운영의 작품은 세 분류로 나누어 분석,정리 하였다. 김진균 또한 먼저 작품세계와 사상을 살펴본 후 , 가곡집 <산너머 저 하늘이>에서 밝힌대로 두 분류로 나누어서 연구하였다. 이렇게 한국적인 요소를 살펴봄을 통해 진정한 한국가곡의 발전을 기대하며, 더불어 한국가곡의 독특한 요소들을 연주자들이 어떻게 표현하는 것이 바람직한가에 대한 생각도 해 볼 수 있기를 바란다. Korean art songs began from <Bongsoonga>, Hong Nan Pa's work in 1920. Since then, Korean art songs had been developed more and more. As it came into 1960's, the unique factors of Korean art songs began to appear notably. This study examined Na Un Young and Kin Jin Gyun, who had vigorously acted in 1960's. First, it considered the work world of Na Un Young, and then tried to find Korean uniqueness that are shown in his works. It classified Na Un Young's works into three categories, and then analyzed and put them in order. Also for Kim Jin Gyun, it tries to classify his works into two categories and study them as it was mentioned in his Korea art song collection, <Sanneomeo Jeo Haneuri>, after it considers his work world and thoughts. Like this, while it tried to find Korean factors shown in Korean art songs, it could find that Korean art songs have become Korean own style works, and moreover, it hopes that players can also consider the matter, which way will be desirable for them to express the unique factors shown in Korean art songs.

Necessity of computer technology to make three-dimensional image and animation have progressed very since the 1950 first system is developed, and nowaday third dimension computer animation and image technique offer very much us new magic tricks. Animation technique is easy if use other medium with some third dimension computer image and while can make equally, what techniques bring third dimension computer image and unique sequence forming in animation medium. This paper sets standard of composition esthetics enemy of correct camera technique in 3D animation manufacture environment and director or animator wished to present alternative of method to do optimum composition of a picture. Herbert ancestor memorial service frame divides into fourth dimension circumference of third dimension, time and action that relate directly with camera among basis component of image esthetics that present and presented. Camera in movie with this theory and camera technique in 3D animation and composition analyzed comparison. Little more creative and various techniques may be producible reference mark because image esthetics principles of such traditional camera technique are applied in composition of a picture that use camera in 3D animation.
