將門記 , 陸奧話記 에 나타난 謀叛의 구조

장영철 ( Young Chul Jang ) 한국일어일문학회 1995 日語日文學硏究 Vol.27 No.1

『將門記』」は私鬪の段階と謀叛の段階との二部構成に分けられるが, 謀叛という言葉は前半部に當る私鬪の段階では見られない. この点はその分だけ將門が自ら謀叛を圖らなかったこと, 且つ謀叛人として始めから規定されてはいなかったことを意味する. 以後『將門記』」後半部の發端の部分で源經基によって將門の謀叛が告發され, さっそく將門が自分の解明に乘り出して朝廷でもこれを受け入れることになっている. ここで見える謀叛の2用例を通じて將門の謀叛が無罪に判明されるわけである. その後, 『將門記』後半部の末尾に集中されて見える謀叛の5用例は主に語り手の言葉として將門またはその一黨を對象にしているが, それは事後的な評價としての意味を持つだけである. 將門が謀叛の行爲を行っている時点ではむしろどの登場人物も語り手もそれを謀叛と稱してはいないのである. 私鬪の段階に留まっていた將門が謀叛という行動の飛躍に至ってしまった重要な原因として, 『將門記』には朝廷による官符の亂發がそれを招いたとも見えることを指摘しなければならない. 『將門記』の本文において4回にわたる官符の發令のうち, 特に3番目の官符は將門としては納得できない致命的な措置になってしまって, その直後將門は今までの順應的な態度を變えて朝廷に對する武力の挑發に踏み出すことになるのである. 謀叛の主體者である將門に對して『將門記』は他の軍記物語と同じく英雄化の裝置をいくつか施している. 本文の冒頭には桓武天皇の5代孫で鎭守府將軍の息子としての將門の血筋が言及され, 以後彼の人生歷程には神沸の利益が數次現われてくる. 將門が天皇を僭稱する直前には神託も現われ, 謀叛に對する正當性を授けることになっている. また, 『將門記』の合戰譚に描かれた將門の武勇は當時の天皇制を脅かすものとして足りなくない. その上, 將門が自分の武力に對する自負心と說得力の持ち主であることを, いたる所で見られる中國故事の引用と共に『將門記』の文章で確認することができる. それに反して, 「陸奧話記」には謀叛の用例が見られず, 朝廷によって派遺された源賴義の追討の活躍が主な關心事になっている. その点, 他の軍記物語が謀叛の主體者を中心人物に設定してある程度英雄化された人物像を描いていることとはよい對照を見せている. 『陸奧話記』の敍述態度はいくつかの源賴義の失敗譚をも含めて, 武家の棟梁としての彼の英雄化に-貫しているし, それは國解の文を抄したという「陸奧話記」末尾の記述と軌を-にしていると思われる. それに加えて, 出羽の山北の부수の主である情原武則は『陸奧話記』の後半部にかいて源賴義を凌駕するほとの活躍を見せている. 彼の卓越した情勢判斷と予測力及び多樣な戰術が大勢を決定つけているとも言えるほどである. その上, 謀叛を起した安倍賴時と貞任には惡行とか野蠻なふりまいはほとんと見られず, 彼らなりの挑發の論理づけが施されている. また, 防ぎと奇襲と退却と打ち死に至るまでの安倍一黨の熾烈な抗爭過程を通して邊方の異質的存在に對する制限された同情心が潛んでいるとも見られる. この点, 衆口の話を拾って一卷を注したという『陸奧話記』末尾のもう一つの記述と關連づけられるし, 特に『陸典話記』の合戰譚に見られる具體的な場面描寫の特長と共に, 『陸奧話記』なりの謀叛の構造を把握することに役だつだろうと思われる.

여성의 역할과 헤이케 모노가타리(平家物語) 구성

장영철 ( Young Chul Jang ) 한국일어일문학회 2012 日語日文學硏究 Vol.83 No.2

The heroines of The tale of Heike show their lives through love and farewell, live and die, entering the Buddhist and going to Nirvana. The tales of heroines are not simply included as a tale of tragic love. They materialize the logic of “All things flow and nothing is permanent” like other men of heroes. They endure a lot of pains through war and struggle with their partners. After their husband and son died, heroines kept in the temple and prayed for the dead. The heroines` function of The tale of Heike effects the presentation of the theme and expension of sympathy.

오픈주방 조리사의 직무스트레스가 조직유효성에 미치는 영향

장영철 ( Young Chul Jang ),이은준 ( Eun Jun Lee ) 한국호텔리조트학회(구 한국호텔리조트카지노산학학회) 2012 호텔리조트연구 Vol.11 No.2

Generally, Hotel employees generally have a hard time in process of providing services such as tall order, difficult customer and so on. However, an organization forces its employees to have respectful and polite service attitudes with a smile even in an unpleasant or a sticky situation during service providing process. Also, as competition intensifies in the hotel business, more efforts for organization innovation such as downsizing, outsourcing and management outsourcing are made. Therefore, an organization demands simplified, specialized and diversified work excessively to the employees, so job insecurity and stress for each employee increase greatly. This service can give necessary information for job performance and then help them to relieve job stress. However, excessive delegation of authority is rather followed by demanding excessive workload and responsibility. It can cause an accumulation of job stress. The important matter is to set a proper scope depending on the situation.

둥글장수풍뎅이 혈구 종류와 식균작용

황두선,장영철,조세열,Hwang, Dooseon,Jang, Young-Chul,Cho, Saeyoull 한국응용곤충학회 2017 한국응용곤충학회지 Vol.56 No.3

본 연구는 둥글장수풍뎅이(Pentodon quadridens bidentulus (Famaire, 1887)) 유충의 혈림프에 존재하는 혈구세포들의 종류와 병원균 침입시 세포 면역을 담당하는 세포를 특정하고 분석하였다. 둥글장수풍뎅이(P. quadridens bidentulus)유충 혈강내에는 과립혈구세포, 부정형혈구세포, 편도혈구세포, 소구형혈구세포, 원시혈구세포, 지방혈구세포 총 여섯 종류의 혈구세포들이 존재하였다. 여섯 종류의 혈구세포 중 과립혈구세포가 병원균 침입 시 형태적 변이와 함께 병원균들에 대한 식균작용을 수행하는 면역세포로 관찰 되었다. 특히, 생체 내에서 병원균 침입시 12시간 안에 활발히 식균작용을 수행하였고 24시간 이후로는 면역 활성화가 줄어들면서 정상상태로 전환되는 것을 알 수 있었다. 세포질 혈구세포의 식균작용도 간혹 관찰 되었으나 나머지 세포들은 면역과 연관된 활성화가 없는 것으로 나타났다. The purpose of this study was to analyze the characteristics of hemocytes in the hemolymph of the larvae of Pentodon quadridens bidentulus and the characteristics of the hemocytes responsible for cellular immunity during pathogen infection. Granulocytes, plasmatocytes, oenocytoids, spherulocytes, prohemocytes and adipohemocytes were found in the circulating hemocytes. Among them, granulocyte were observed as cells responsible for immunological phagocytosis during entry of foreign substances. In particular, it was observed that the most active phagocytic action occurred within 12 hours in vivo, and that after 24 hours, the immune activation was reduced and converted to a normal state. Plasmatocytes were occasionally observed as immunological response, but the remaining hemocytes were not related to immunological activation.

Recently, the usage of an exercising treadmill has increased in Korean homes. Along with increasing utilization of these machines, injuries relating to the inadvertent usage of the machine have gradually increased for the last several years. The purpose of this study is to identify the feature of this type of injury, thereby to help prevent and to raise an awareness of the potential injury. 25 patients who had been admitted to Hangang Sacred Heart Hospital from January 2002 through March 2004 were investigated retrospectively. Age, sex, place of injury, the area and the extent of injury, treatment and prognosis were analyzed for each case. All injuries involved in the children with an average age of 3.5 years. This new type of injury was at least a deep second-degree burn of the friction-burn type in all cases. Most of them primarily involved hands. Inattention of the guardian was the main cause of such injuries. 68% of the cases needed an operation such as a split-thickness skin graft or a full-thickness skin graft. In this study, authors reached a conclusion that such injuries may be prevented by an education of the potential risks of using a treadmill and by developing additional safety devices.

PCS 대역과 W-CDMA 대역 겸용 광대역 이중 편파 안테나 설계 및 구현

이원희(Won-Hui Lee),장영철(Young Chul Jang) 한국전자파학회 2008 한국전자파학회논문지 Vol.19 No.10

본 논문에서는 PCS 대역과 W-CDMA 대역 겸용 광대역 이중 편파 안테나의 설계 및 구현을 위해 L자 형태의 급전과 원형 단일 마이크로스트립 패치 안테나를 제안하였다. 안테나의 특성 해석을 위해 상용 고주파 시뮬레이션 툴인 HFSS를 이용하였다. 설계된 안테나는 제작하여 HP8753D 네트웍 분석기에 의해 측정되었다. 설계된 측정된 임피던스 대역폭은 560 ㎒(VSWR<1.5), 평균 이득은 6.56 ㏈i로 측정되었다. 두 개의 포트 사이의 격리도 특성은 최소 -14 ㏈에서 최대 -40 ㏈로 측정되었다. 이와 같은 결과로 제안된 안테나는 이동 통신 응용 및 중계기 안테나로 적합하다고 판단된다. In this paper, a dual polarized broadband antenna fed by L-shaped strip for the Korea PCS band and W-CDMA band is presented. To analyze the characteristics of the designed antenna, we used commercial simulation tool(HFSS). The designed antenna was fabricated and measured using HP8753D vector network analyzer. The measured impedance bandwidth(VSWR<1.5) is 560 MHz and the measured average gain is 6.56 ㏈i. The measured isolation characteristic between two ports is -14 ㏈(min.)~-40 ㏈(max.). These results are proper for the mobile communication application and repeater antenna.
