Abstract - In this thesis, we propose a QoS supporting method on wireless ad hoc-based active network for improving reliability. On the loss of route path, the existing DSR routing protocol has several problems with wireless network communication because of decease of data reception rate and increase of network load. The proposed method improves reliability of data transfer by using functions of active network. That is, by using functions of active nodes and active packets, the proposed method supports QoS with reservation transfer method that saves data packets on transfer at intermediate nodes with lost path and then re-transmit the packets after route reconfiguration.

Started from a small size Seung-Jik Park Shop, one of the oldest in Korean modern history of commerce, and grown with traditional Korean spirit of politeness and perseverance, Doosan Group today has become one of the largest groups of companies including such a gigantic company as Doosan Heavy Industries Co., Ltd. This study aims to explore the courses of growth and development of Doosan Group from historical and functional point of view and extract the characteristics of growth and the modes of behavior in order to define the growth factors. The method adopted for the study is based on the management history with particular focus on entrepreneurs involved. In 1896, the year classified in this study as embryo period of Doosan Group, ‘Maeheon’ Seung-Jik Park opened Seung-Jik Park Shop selling drapery. Then he established Kwang Jang Co, and Kong Ik Sa, a trading house, developed cosmetic product Parkabun and ventured into beer industry through the acquisition of Sohwa Kirin Beer. In this embryo period, the factor that enabled his companies to grow and develop was the management philosophy based on harmony, thrifty, honesty and trust that formed the company motto and enhanced the image of the companIes. The focus was rather on specialization of organizations for growth than diversification of activities for expansion. In the beginning his business was mainly on drapery with major focus on quality and reliability. By the time he ventured into such commodity business as cosmetics and beer, the quality of products be came the prime target to pursue and achieve. This period could be seen as initial stage of the group to accumulate the capital required for further growth. From the year 1951 when ‘Yonkang’ Doo-Byung Park began to lead the group, the formation period set in place. In such time of Rehabilitation followed by social chaos, Sohwa Kirin Beer was transformed into Oriental Brewery Co., Ltd. and Doosan Group began to be formed. This formation period marked the dawn of Doosan Group pioneering the beer market, launching construction and machinery industries and exploring the overseas markets. This period was the time when the need for the management to be separated from the capital was strongly felt in order to maximize the management philosophy carried forward from the initial stage of the Doosan Group. The growth factor from the management point of view was the corporate philosophy based on harmony, honesty and public service spirit. In 1974, a new era began with the appointment of management expert Soo-Chang Jung as Chairman and Chief Executive Officer. It was a major turning point for Doosan Group. The efforts of the top management in this period could be characterized by its focus on creation of growth paths for electronic industries, accumulation of technologies through strategic alliance or merging with the companies of advanced countries, and expansion or realignment of existing businesses. The first growth factor in this period was the emphasis of creativity that provided the basis and momentum for healthy management and the second was organizational restructuring to be prepared for acquisition and merging and maintain the specialty of each business unit. Take-off period started with the arrival of Chairman Yong-Kon Park in 1981 and continued until 1995. In this period, development of overseas markets was reinforced in the areas of beer. construction, electronics, glass, machinery and trading while new businesses were actively explored. The Group was pressing forward with continuous expansion, horizontally as well as vertically. The growth factors from the management point of view were customer-satisfaction, priority on Quality, innovation, recruitment of talented people as well as organizational change aimed for diversification and specialization through the new system and mixed use of business divisions and teams. The year 1996 saw the beginning of innovation period of Doosan Group, As the external e

In this paper, we propose a bidirectional mobile Ad Hoc routing protocol based on AODV(ad-hoc on-demand distance vector routing) with QoS(quality of service) support. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS guarantee between end points is a very important issue. The existing AODV routing protocol is implemented to use only BE (Best Effort) service. However, actual wireless mobile environment requires to reduce a waste of communication resources and meet with the real-time change of data paths by setting up routes with QoS support, considering available communication resources at each node in advance. Therefore, in this thesis, we propose an adaptive QoS support method using hello message in order to rapidly meet with the change of available communication resources and to smoothly perform route maintenance. For performance evaluation, we analyzed the average data reception rate. At that time, we used evaluation parameters such as node's mobility-stop time, hello message period, and packet priority, considering the node's mobility and the number of best effort/QoS data flows. As results, we found that with our proposed method the average data reception rate was increased 16.293%, 15.914%, 17.238% for 300 mobility-stop second case and 4.809%, 4.264%, 2.956% for 300 mobility-stop second case.

과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

후퇴지향적 想像力 : Gottfried Benn의 詩集「靜詩」분석 aufgrund des Analysierens der statischen Gedichte von Gottfried Benn

이승욱 순천향대학교 1992 논문집 Vol.15 No.3

「Statische Gedichte」 ist das Hauptwerk, das Benns spatere Phase vertritt. Die meisten Gedichte in dieser Sammlung sind 1935-1945 entstanden. Also sind sie Werke, die sahrend sei- ner inneren Emigration geschrieben wurden. Auch in diesen Werken wird seine Hauptpoetik (Ab- solute Poesie/Statisches Gedicht) praktiziert und formuliert. Diese Arbeit versucht gemaβdem Gesichtspunkt 「Statische Gedichte」zu analysieren. Der Ge-sichtspunkt.ist die regressibe Einbildungskraft, die in fast allen Gedichten zum Vorsche- in Kommt. Sie ist eine Tiefenstruktur. Sie bezieht sich auf das zentrale Thema jedes Gedich- tes, Sprache, Stimmung usw. So ist das Hauptanliegen dieser Arbeit, die Beziehungen zu betrachten. Durch diese Betrachtungen wird die Eigenschaft der 「Statischen Gedichte」deutlich gemacht. Dadurch wird auch die Eigentumlichkeit von benns spaterer Poesie offenbart.

格의 相關性에 대하여

李承旭 단국대학교 인문대학 국어국문학과 1970 國文學論集 Vol.4 No.-

체언의 격이란 글월 가운데서 그 체언이 드러내는 다른 성분과의 관계를 말한다. 이러한 격의 운용은 일정한 격표시의 형태소와 더불어 체언이 어형변화를 함으로써 실현되며, 이 변화를 격변화 혹은 곡용(Declension)이라 이르기도 한다. 체언을 다른 품사군과 구별하여 하나의 통사적 성분단위로 범주화하는 특징이 바로 이것이다. 그러나, 격은 다만 분석된 일정한 형태소의 특징만으로 결정되어지는 것만은 아니다. 가령, i) 학교로 간다. ii) 병으로 죽었다. 에서 i)과 ii)에 실현된 <-로/으로>가 같은 형태라 해서 관계하는 격도 같다고 할 수는 없다. 그렇기 때문에 격의 관계는 표면상의 형태론적 소성만으로 특징지울 수 없는 내적 언어형식을 가진다. 전접되는 체언과의 관계보이는 오히려 그 체언이 다른 성분에 대하여 어떠한 관계의 자격을 띠는가 쪽에 걸치게 된다. 이렇게 해서, 격은 대체로 용언의 어휘항목이 드러내는 의미에 의하여 지배되는 관계에 있게 되며, 이 관계의 연환속에서라야 그 실천적인 기능이 구체적으로 기술될 수 있다. 그러므로, 격에 대한 고찰은 격 자체의 의미적 소성만으로 분석되어지거나, 체계화되어질 수 없는 관계성을 내포하고 있게 되는 것이다. 원칙적으로 격의 표시는 전접되는 체언의 어휘항목에 이끌려 결정되는 경향보다는 이와의 통사관계에 놓여지는 용언의 어휘항목에 의존되어 선택된다고 하는 것이 오히려 논리적으로 무리가 없음을 미루어 알게 되었다.

곳트프리트 벤의「詩를 테마로 한 詩들」의 分析 : einer Versuch, die Tiefenstruktur der Bennschen Dichtung aufzubauen 벤 文學의 심층구조를 얻기위한 試論

이승욱 순천향대학교 1990 논문집 Vol.13 No.2

Die moderne Dichtung ist vor allem durch das eigentumliche Ineinanderubergehen von produktiver Tatigkeit und poetologischer Reflexion gekennzeichnet. Die Bennsche Dichtung ist keine Ausnahme davon. Bei Benn erscheint dieses phanomen eher viel nackter und unmittelbarer als bei anderen Autoren. Im weitesten Sinne mogen fast alle seine Werke wesentlich als Variante dafur gesehen werden. Diese Wechselbeziehung von produktiver Tatigkeit und poetologischer Refluexion erreicht ihre Kulmination im Themati-schwerden des Gedichtes im Gedicht. Die Gedichte, 「Leben-niederer Wahn」, 「Wer allein ist-」, 「Verse」, 「Gedichte」,「Ein Wort」,「Statische Gedichte」, 「Chopin」,「Die Form」,「Satzbau」,「Wirklichkeit」,「Gedicht」,「Worte」usw. sind typische Beishpile dafur. In den oben genannten Gedichten handelt es sich hauptsachlich um die Weltanschauung des Dichters, die poetische Existenz, den dichterischen Schaffensprozeβ, und die fertige Werkgestalt, mit anderen Worten um die gesamte Poetologie von Benn selbst. Das Hauptanliegen der vorliegenden Untersuchung liegt darin, zu beweisen, 1. daβder Kernpunkt von Benns Poetik kurch Analysieren dieser Gedichte systematisch beschrieben und rekonstruiert werden kann, 2. daβaufgrund dieses Analysierens die Grundsituation, etwa die Tiefenstruktur der Bennschen Gedichte aufgebaut werden kann, weil die poetologische Reflexion nicht nur als theoretisch-programmatische Poetik steht, sondern weil sie als Integrationselement der Textsstruktur selbst anerkannt wirk. Ein weiterer Grund besteht darin, daβdie Poetologie eines Dichters in gewissem Punkt fur eine theoretische Systematisierung seiner inneren Einbildungskraft gehalten werden kann. Demgemaβwerden zuerst die oben genannten Gedichte nach drei festgesetzten Gesichtspunkten analysiert. Wie schon gesagt, aufgrund dieses Anlysierens wird dann das Kern-system der Bennschen Poetologie bzw. die konstanten Stromungsphasen der Bennschen Einbildungsdraft aufgebaut. Zum Schluβwerden in Beziehung zu dieser Tiefenstruktur die Neigung zur Regression und zum Narzismus, die sich in Bennschen Gedichten zeigen, ein wenig erortert.

국산밀의 제빵에 대한 효소의 영향

이승철,하정욱 慶南大學校 附設 工業技術硏究所 1997 硏究論文集 Vol.15 No.1

밀은 국내 소비 곡물 중 2위를 차지하고 있으나 대부분 수입에 의존하고 있다. 최근들어 국산밀에 대한 관심과 호응의 증대로 국산밀의 소비가 증가하고 있으나, 국산 밀가루에는 화학적 첨가물이 전혀 함유되어 있지 않아 제빵 적성이 수입밀에 비하여 뛰어나지 못한다. 국산밀의 제빵 적성을 향상시키기 위하여 천연 밀 단백질인 활성 글루텐과 효소를 첨가하여 제빵적성을 조사하였다. 먼저 밀가루의 0.1%에 해당하는 α-amylase, bromelain, 복합효소(단백질 가수분해 효소, 전분 가수분해 효소)를 각각 첨가한 결과, 빵이 물러지고 부피팽장이 현저히 저하되었다. 이를 개선하기 위하여 천연 밀단백질인 활성 글루텐 첨가 함량을 조절하여 제빵한 결과, 대조구인 수입밀에 비하여 10%의 활성 글루텐을 함유한 빵에서 부피 팽창이 가장 좋았으며, 15%의 활성 글루텐을 첨가한 빵에서 색도가 가장 수입밀로 만든 빵에 접근하였다. 10%의 활성 글루텐에 0.0001%의 α-amylase를 첨가하여 제빵했을 때, 부피 팽창도 좋고 맛도 우수한 국산밀 빵을 제조할 수 있었다. 따라서, 천연 밀단백질인 활성 글루텐과 효소를 첨가하여 국산밀의 제빵능력 향상을 기할 수 있었다. To increase utilization of Korean wheat flour, bread-making characteristics of that with addition of enzymes were observed. When α-amylase, bromelain, and complex enzyme (contains protease and amylase) were added to the concentration of 0.1% of wheat flour, resulted breads shown insufficient volume increase. The addition of vital wheat gluten, natural wheat protein, to Korean wheat flour shown positive effect on bread-making ability. At concentration of 10% vital wheat gluten, volume increase of bread was best, while color of bread was nearest to imported wheat flour-bread at 15% gluten. By sensory test for breads, which were made with several combination of Korean wheat flour, vital wheat gluten, and enzyme, bread contains additional 10% vital wheat gluten and 0.0001% of α-amylase acquires best points at texture and taste. With above results, we could improve bread-making ability of Korean wheat flour with addition of vital wheat gluten and α-amylase.
