This paper is aimed at proposing the policies for managing archives in the process of promoting Electronic Government System. Although there have been many studies of electronic government project and plans for its establishment, this research examines the electronic government system and its problems on the basis of archival science. What I acquired in this paper is as follows. The development of information technology needs great changes ranging from the nation to the individuals. It becomes common that the use of computerized program for business purposes, computerization of information materials and the effective way of search use of electronic documents. Therefore, more and more countries all over the world have been seeking to promote 'Electronic Government', which applies the fruits of the development in information technology to administration process. Recently, Korea has been rapidly entered into the 'Electronic Government' system being against the traditional way of administration. In electronic government system, the 'Life Cycle' of public records will be computerized. Therefore, it is important to change and develop along with the government's policies for 'electronic government project' in the archival management system. This means that the archival management system which have put emphasis on the textual records should be converted to electronic records system. In other words, the records management in electronic government system requires not the transfer and preservation of the records but the consistent management system including the whole process of creating, appraising, arranging, preserving and using the records. So, the systematic management of electronic records plays an important role in realization of electronic government, but it is a subject to be realized by electronic government at the same time. However, the government have overlooked the importance of archival management for long time, especially the importance of electronic records management system. First of all, this research attempts to infer limits and problems through the theoretical considerations of the existing studies for electronic government and to clear up the relations between electronic government and archival management. Based on this, I'll seek to progress the study through reviewing the present condition of archival management in the process of promoting electronic government and suggesting the policies for enhancing the successful electronic government and the construction of scientific archival management system. Since early 1990, many countries in the world have been making every effort to concrete 'Electronic Government'. Using the examples in other nations, it is not difficult to recognize that the embodiment of electronic government is closely connected with the archival management policies. Korea have completed legal and institutional equipments including the new establishment of "Electronic Government Law" to realize electronic government. Also, Korea has been promoting electronic government with the Ministry of Government Administration and Home Affairs and Government Computer Center as a leaders. Though managing records, especially the management of electronic records is essential in electronic government system, we haven't yet discussed this section in Korea. This is disapproved by the fact the Government Archives and Records Service has played little role in promoting electronic government project. There are two problems relating this environment. First, present system can't meet the consistent 'Life Cycle' ranging from the creation to the preservation of electronic records. Second, the 'Life Cycle' of electronic records is divided into two parts and managed separately by GCC and GARS. The life of records is not end with the process raged from creation to distribution. On the other hand, the records are approved their value only whole procedures. Therefore, GARS should play a deading role in designing and establishing the archival management system. The answer to these problems, is as follows. First, we have to complete the electronic records management system through introducing ERMS not EDMS. This means that we should not change and develop towards ERMS simply with supplementing the current electronic records management system. I confirm that it is important and proper to establish ERMS system from the very beginning of the process of promoting electronic government. Second, I suggest the developmental integration of GARS and GCC. At present, the divided operations of GCC and GARS, the former is in charge of the management center for electronic business and the latter is the hub institution of managing nation's records and archives result in many obstacles in establishing electronic government system and accomplishing the duties of systematic archival management. Therefore, I conclude that the expansive movement towards 'National Archives' through the integration among the related agencies will make a great contribution to the realization of electronic government and the establishment of archival management system. In addition to this, it will be of much help to constitute and operate the 'Task Force' regarding the management of electronic records with the two institution as the central figures.

The purpose of this research was to summarize Korea and China's researches on Noh and to examine main domain in this field, by investigating the academic books and articles published in two countries. In 1960s, since Nohgaku has been introduced to China, academic articles on Zeami's theories and aesthetics have emphasized on aesthetic characteristics of Chinese plays and Japanese Nohgaku through the similarities of oriental plays. The number of researches on Kabuki is almost twice as that of researches on Noh in China. While most researches on Kabuki were compared with the styles and music of Pecking Opera and the theatrical theories of liyu[李漁], those on Noh has been highlighted the comparative studies on $Y{\bar{o}}kyoku$[謠曲], Chinese Noh plays. The main difference among the researches on $Y{\bar{o}}kyoku$ in Korea and China was the material regarding characters of Noh. Because song yuanzaju[宋 元雜劇]and Nohgaku in Chinese-Japanese plays were the mature form of the classic plays and those were representative of traditional nation plays, this researches tried to ascertain the cultural origins of two countries regarding the aesthetic characteristics by referencing lyrical and narrative features[曲詞] of yuanzaju[元雜劇]and the classic waka of Nohgaku. While the comparative studies on Noh and song yuanzaju and kunqu[昆劇] in China were prevalent, national researches have emphasized on the inner world of the main character and dramaturgy through the verbal description of Noh. Especially, this research tried to investigate the inner world of the main character and the intention of the writers through the verbal description of Noh authorized in the history of the works. Also, the researches on Buddhism in the Middle Ages and religious background were examined significantly. In addition, the $Y{\bar{o}}kyoku$ has influenced on European modern playwrights and the comparative studies between the materials of $Y{\bar{o}}kyoku$ and Western modern plays were concerned. In Korea, the comparative studies on Noh between Korea abd Japan has been most focused on the origin theory of Noh. The fact that appearance theory of Noh had originated from Sangaku was common opinion among Korean, Chinese, and Japanese scholars. However, they are agree with the opinion that according to the formation of the different genres, Noh's mainstream was different among three countries despite of the same origin. Yuan drama and Noh play have the same origin, but different branch. In relation to the Noh's origin theory, there are literature comparative studies in religious background, the studies presumed the origin of instrumental music related to those in mask plays, and the comparative studies between Korean mask plays and $ky{\bar{o}}gen$ of Nohgaku. Kyogen is the Comedy inserted among the stories in Nohgaku performed in just one day. Therefore, $ky{\bar{o}}gen$ must be discussed separately from the relations of 'shite[任手]'s inner action veiled with masks. This research figured out that the lacking points of the two countries' researches were the acting methods of Noh. Academic articles written by foreign scholars studying Korean and Chinese theatres should be included when this issue will be dealt with. In Korea and China, translation studies and writings regarding Nohgaku have studied by those who are major in Japanese literature or oriental literature. This case is the same in Korea in that scholars whose speciality is not theatre, but Japanese literature has studied. Therefore, this present study can give a good grasp of whole tendency on Nohgaku's research in theatre fields.

본 연구의 목적은 옛사람들이 '연'이라는 식물소재를 활용한 방법과 그로부터 취하고자 했던 가치와 의미, 감상 태도 등에 대한 실제적 사례들을 고찰하는데 있다. 이를 위한 연구의 방법은 연에 대한 감상과 관념세계가 반영된 시문과 회화를 고찰하고 해석하는 기술(description)적 연구방법이 사용되었다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 연의 관상 가치는 대규모 집단식재와 부지규모의 소규모 식재, 분연(盆蓮)으로 나누어 볼 수 있었다. 특히 대규모 면적에 집단적으로 식재된 연은 여타의 초화류와 차별화되는 독특한 경관을 제공하였다. 별서와 후원 등 사적인 공간에 연지를 조성하고, 연을 애호한 여러 사례들을 확인할 수 있었다. 이러한 장소는 연이 개화할 무렵에 아회의 장소 등으로 활용되었다. 작은 연지조차 조성하기 어려운 경우에는 분지를 이용하여 연을 즐기기도 하였다. 또 꽃과 잎, 줄기와 연밥 등 세부요소 모두의 관상가치가 뛰어난 점은 연의 또 다른 특징의 하나로 볼 수 있다. 둘째, 주돈이의 '애련설(愛蓮說)'에 '향원익청(香遠益淸)'으로 표현된 향기는 연의 중요한 매력 중 하나이다. 전통정원에 있어서 연은 향기를 제공하는 후각적 요소로 활용되었다. 옛사람들은 연의 향기를 단순히 즐기는 것에 더해 '군자의 품격'에 비유되는 상징물로 여겼으며, 이를 시문과 그림으로 표현하였다. 셋째, 연은 청각적 요소로도 활용되었다. 즉, 수면과 넓은 연잎에 빗방울이 어우러져 내는 소리를 '연당청우(蓮塘廳雨)' 또는 '하당야우(荷塘夜雨)'라 하여 운치 있는 소리로 즐겼다. 넷째, 연꽃을 구경하는 여름놀이를 '세속에 오염된 마음을 씻는다'라는 의미의 세심(洗心)놀이라고 하였다, 이러한 풍류는 일반 서민들로부터 왕가에 이르기까지 폭넓은 계층이 즐겼다. 이 밖에 연과 관련된 풍류로 큰 연잎과 속이 빈 줄기의 특징을 이용하여 술을 마시는 방법인 '벽통주(碧筒酒)' 혹은 '하심주(荷心酒)', 상비주(象鼻酒)가 있다. 또 유교의 영향으로 남녀유별이 엄격하던 조선시대에 연밥과 '채련곡'은 남녀 간의 연애감정을 표현하기 위한 중요한 기호(記號)가 되기도 하였다. 따라서 많은 '채련곡'이 전해지며, 남녀 간의 애정을 묘사한 여러 풍속화에는 연당이 배경으로 등장한다. 연은 고대 이래로 사상과 종교 등 문화적 배경을 초월해 폭 넓은 계층이 애호하여 왔다. 이러한 연유로 인해 연이 갖는 다양한 상징적 의미와 사찰 등 종교시설과 관련된 식재 사례를 다각적으로 고찰하지 못한 점은 본 연구의 한계이며 추후 연구과제이기도 하다.

지구의 기후 변화를 유도하고 제어하는 가장 중요한 역할을 하는 것은 해양의 해류이다. 황해는 수심이 동해에 비해 매우 얕고, 다양한 바람과 조류, 강물의 유입, 동중국해에서의 해수 유입 등 외력의 영향으로 해수의 순환과 해류가 상당히 복잡하다. 황해난류는 겨울철 황해의 대표적인 해류로서 겨울철 황해와 동중국해 바람 변동성과 밀접한 관련이 있으며, 황해의 수온과 염분 분포에 큰 영향을 주어서 중등학교 교과서에서 중요하게 다루어질 필요성이 있다. 2015 개정 교육과정 기반 중등학교 과학 및 지구과학 교과서의 황해난류와 관련된 내용을 분석하였다. 또한 해류의 시간 변동성에 대한 교사들의 인식을 조사하기 위해 중등학교 과학 교사들을 대상으로 설문조사를 실시하였다. 대부분의 교사들은 황해난류가 우리나라 서해안으로 연중 북상하고 있으며 일반적인 난류와 같이 여름철에 강하다는 잘못된 지식을 가지고 있는 것으로 나타났다. 황해난류는 해류의 세기가 강한 계절변동성을 가지는 북한한류와 달리 해류 자체가 연중 항시 존재하지 않으며 겨울철에만 발생하는 해류이다. 이러한 교사들의 교과내용 지식에 대한 오류는 북한한류가 겨울철에 강하다는 오개념을 가지게 된 연유와 유사한 배경을 가지고 있었다. 따라서 본 연구에서는 황해난류에 대한 교과서 내용의 오류를 분석하여 제시하였다. 또한 학생들과 교사들의 데이터 리터러시 함양을 위하여 탐구활동에서 활용할 수 있는 황해난류에 대한 수업 자료를 개발하였다. 황해 해수면 온도를 가시화할 수 있는 GUI 프로그램을 소개하였고, WOA (World Ocean Atlas) 2018 해양 실측 수온 및 염분자료와 국립해양조사원에서 생성한 해양 수치모델 재분석자료를 활용하여 수온과 염분의 공간 분포를 도시하는 자료를 개발하여 제시하였다. 이러한 해양 자료를 활용한 데이터 시각화과정은 교사들의 오개념을 개선하고, 나아가 학생들과 교사들의 해양 리터러시뿐만 아니라 데이터 리터러시도 제고하는 계기가 될 것으로 기대된다.

Visual media transmits image and information reproduced in large quantities, such as a photography, film, television, video, advertisement, or computer image. Correspondence to the students' reception and recognition of culture in the future. arrangements for the field of studies of visual culture. 'Visual Culture' implies cultural phenomena of visual images via visual media, which includes not only the categories of traditional arts like a painting, sculpture, print, or design, but the performance arts including a fashion show or parade of carnival, and the mass and electronic media like a photography, film, television, video, advertisement, cartoon, animation, or computer image. In the world of visual media, Image' functions as an essential medium of communication. Therefore, people call the culture of today fra of Image Culture', which has been converted from an alphabet convergence era to an image convergence one. Image, via visual media, has become a dominant means for communication in large part of human life, so we can designate an Image' as a typical aspect of visual culture today. Image, as an essential medium of communication, plays an important role in contemporary society. The one way is the conversion of analogue image like an actual picture, photograph, or film into digital one through the digitalization of digital camera or scanner as 'an analogue/digital commutator'. The other is a way of process with a computer drawing, or modeling of objects. It is appropriate to the production of pictorial and surreal images. Digital images, produced by the other, can be divided into the form of Pixel' and form of Vector'. Vector is a line linking the point of departure to the point of end, which organizes informations. Computer stores each line's standard location and correlative locations to one another Digital image shows for more 'Perfectness' than any other visual media. Digital image has been evolving in the diverse aspects, such as a production of geometrical or organic image compositing, interactive art, multimedia art, or web art, which has been applied a computer as an extended trot of painting. Someone often interprets digitalized copy with endless reproduction of original even as an extension of a print. Visual af is no longer a simple activity of representation by a painter or sculptor, but now is intimately associated with a matter of application of media. There is some problem in images via visual media. First, the image via media doesn't reflect a reality as it is, but reflects an artificial manipulated world, that is, a virtual reality. Second, the introduction of digital effect and the development of image processing technology have enhanced a spectacle of destructive and violent scenes. Third, a child intends to recognize the interactive images of computer game and virtual reality as a reality, or truth. Education needs not only to point out an ill effect of mass media and prevent the younger generation from being damaged by it, but also to offer a knowledge and know-how to cope actively with social, cultural circumstances. Visual media education is one of these essential methods for the contemporary and future human being in the overflowing of image informations. The fosterage of 'Visual Literacy' can be considered as a very purpose of visual media education. This is a way to lead an individual to the discerning, active consumer and producer of visual media in life as far as possible. The elements of 'Visual Literacy' can be divided into a faculty of recognition related to the visual media, a faculty of critical reception, a faculty of appropriate application, a faculty of active work and a faculty of creative modeling, which are promoted at the same time by the education of 'visual literacy'. In conclusion, the education of 'Visual Literacy' guides students to comprehend and discriminate the visual image media carefully, or receive them critically, apply them properly, or produce them creatively and voluntarily. Moreover, it leads to an artistic activity by means of new media. This education can be approached and enhanced by the connection and integration with real life. Visual arts and education of them play an important role in the digital era depended on visual communications via image information. Visual me야a of day functions as an essential element both in daily life and in arts. Students can soundly understand visual phenomena of today by means of visual media, and apply it as an expression tool of life culture as well. A new recognition and valuation visual image and media education is required to cultivate the capability of active, upright dealing with the changes of history of civilization. 1) Visual media education helps to cultivate a sensibility for images, which reacts to and deals with the circumstances. 2) It helps students to comprehend the contemporary arts and culture via new media. 3) It supplies a chance of students' experiencing a visual modeling by means of new media. 4) There are educational opportunities of images with temporality and spaciality, and therefore a discerning person becomes to increase. 5) The modeling activity via new media leads students to be continuously interested in the school and production of plastic arts. 6) It raises the ability of visual communications dealing with image information society. 7) An education of digital image is significant in respect of cultivation of man of talent for the future society of image information as well. To correspond to the changing and developing social, cultural circumstances, and the form and recognition of students' reception of them, visual arts education must arrange the field of studying on a new visual culture. Besides, a program needs to be developed, which is in more systematic and active level in relation to visual media education. Educational contents should be extended to the media for visual images, that is, photography, film, television, video, computer graphic, animation, music video, computer game and multimedia. Every media must be separately approached, because they maintain the modes and peculiarities of their own according to the conveyance form of message. The concrete and systematic method of teaching and the quality of education must be researched and developed, centering around the development of a course of study. Teacher's foundational capability of teaching should be cultivated for the visual media education. In this case, it must be paid attention to the fact that a technological level of media is considered as a secondary. Because school education doesn't intend to train expert and skillful producers, but intends to lay stress on the essential aesthetic one with visual media under the social and cultural context, in respect of a consumer including a man of culture.

본 연구는 곡성 함허정(전남유형문화재 제160호)을 중심으로 '현장조사 문헌조사 인터뷰' 등의 연구방법을 토대로 연구대상 일원의 풍수형국과 경관짜임 및 조영의도 그리고 의미경관의 특성을 추적한 것이다. 함허정 일원의 입지 및 조망적 조영특성의 분석과 해석의 일환으로, 함허정 일원의 경관상에 드러난 호혜적 자연관과 경관짜임이 어떠한 형태 및 방식으로 표출되었는가를 구체적으로 밝힌 연구결과는 다음과 같이 축약된다. 첫째, 함허정은 심광형(沈光亨, 1510~1550)이 중종30년(1535)에 군촌(현(現). 전남 곡성군 입면 제월리)에 처소 및 강학을 위한 군지촌정사를 창건한 이후, 지근거리에 1543년 학문연구와 유식(遊息)을 위해 지은 누정이다. 함허정과 군지촌정사가 자리한 군촌마을은 순자강(섬진강)을 마주한 전형적인 배산임수 국면인데, 진산인 동악산은 소가 강가에 누워 한가로이 되새김질 하는 와우형(臥牛形)으로 해석되며, 함허정 일원은 목동(牧童)이 강가에서 피리를 부는 형국으로 와우(臥牛)가 적초(積草案, 풀더미)를 구비하여 평안과 풍요를 누릴 수 있는 길처로 회자된다. 특히, 함허정 뒷동산은 거북이 용궁으로 입수하는 혈맥으로 거북(또는 자라)의 등 위에 앉은 건물[구형(龜形)]이 함허정이며, 절벽 아래 남측의 하중암도(河中巖島)인 구암조대(龜巖釣臺)와 용암(龍巖)은 거북이 지향한 해중 신선경(海中 神仙景)으로 해석된다. 둘째, 함허정은 곡성8경의 제3경 순강청풍과 제9경 설산낙조(雪山落照)의 풍광시점장이면서, 곡성 입면8경의 제2경 함허순자와 제3경 천마귀암(天馬歸岩)의 풍광시점이기도 하다. 한편 음양접합과 같은 '산태극(山太極) 수태극(水太極)'으로 배열된 순자강5곡의 제4곡 경물로서 도학 및 성리학적 토포스로 본 초월적 풍경이자 감각적 투시를 통한 굽음의 미학으로 재생산되고 있다. 특히 비변사인방안지도(18C 중엽)와 옥과현지(1788년) 등에 순자강5곡 중 제2곡 합강정과 제4곡 호연정(함허정), 그리고 제3곡 무진정이 묘사되었음을 볼 때 순자강5곡 경물은 피안(彼岸)과 차안(此岸)의 세계를 넘나들며 선경세계로 귀의하는 장소정체성은 물론 조선후기 명소적 연계경관으로서의 지명도를 엿볼 수 있다. 셋째, 비워둠의 미학이 절묘하게 드러난 함허정은 상수리나무 굴참나무 소나무 등 노거수 수림경관, 구암조대와 용암, 첩석(疊石) 등 바위경관, 군촌마을 문화경관 등이 지근경(至近景)으로 펼쳐지고, 중경요소로 순자강 평호(平湖)와 마산봉, 고리봉 등이 산악경관으로 조망되며, 동쪽에서 서쪽으로 고리봉 마산봉 무등산 설산 등이 개방성 강한 $180^{\circ}$ 조망범위로 펼쳐진다. 특히 군지촌정사의 사랑채인 망서재(望瑞齋)의 당호는 "서석산(瑞石山)을 전망하는 집"이라는 뜻을 갖는데, 조산인 무등산과 설산을 앙경(仰景)하는 등 다채로운 차경(읍경(揖景), 환경(環景), 원근(遠近), 앙부경관(仰俯景觀))에 대한 조망지향적 의도가 중층적(中層的) 경관짜임을 통해 구현되고 있다. 넷째, 실존[주거(住居) 강학처(講學處)]과 이상향[누정(樓亭) 재실(齋室)]이 접합된 군지촌 정주환경의 살림집[제월당], 강학처[군지촌정사], 누정[함허정], 재실[구암사, 청송심씨 4현 배향] 및 묘역 등은 '생성-풍요-초월-회귀'로 이어지는 사대부들의 생애주기와 관련한 의미론적 연계경관으로 인식된다. 특히 함허정 관련 시문은 순자강 일대의 가경 예찬과 유유자적한 삶에 대한 호혜적 자연관 묘사가 주를 이루고 있음을 주지할 때, 함허정은 자연귀의와 안분지족의 요체이자 거점처이며, 수심양성(修心養性)하는 은일지소로서의 현학성이 형이상학적 의미경관으로 표출된다.

대부분의 공익성을 띈 콘텐츠들은 진부한 내용으로 메시지가 표면에 드러나는 경우가 많은데, 관객들은 이러한 콘텐츠를 흥미롭게 받아들이지 않는다. 애니메이션 또한 공익적 메시지를 전달하려다 보면 내용이 전반적으로 진부해질 수밖에 없는 것이 사실이다. <북극곰 파오>(PAO The Polar Bear, 2013)는 진부하고 교과서적인 내용인 지구 온난화 문제를 이야기함에 있어서 관객에게 흥미로운 경험이 되도록 하는 것에 초점을 두고 제작하였다. 또한 라이브 윈도우(Live windows)의 특성을 활용하여 애니메이션을 보는 것에 그치지 않고 관객의 참여를 통해 서사를 이루어낼 수 있도록 다중 형식 스토리(The Multiform Story)로 구성하였다. 본 논문에서는 <북극곰 파오>의 제작 사례를 통하여 극장과 라이브 윈도우에서의 차이점에 대하여 알아보고 이를 토대로 관객 참여를 위한 인터랙션 활용 사례를 살펴본다. 극장과 라이브 윈도우의 차이에 대해서는 장소의 특성에 따른 환경적 측면과 관객의 차이에 대해 분석해 보고, 인터랙션의 활용 사례는 불특정 다수를 위한 사용자 환경 디자인과 인터랙션에 대한 반응으로 서사가 바뀌는 과정을 중심으로 살펴보고 밀라노 광장에서의 상영 결과를 통해 공공예술로서의 애니메이션이 나아가야할 방향에 대하여 제시해본다. 라이브 윈도우의 특성상 <북극곰 파오>의 관객은 애니메이션을 보러 온 관객이 아니라 각기 다른 목적지를 향해 가고 있는 거리의 사람들이다. 이들을 대상으로 서사를 가진 애니메이션을 상영한다는 것은 새로운 시도였다. 밀라노 광장에서 상영이 시작되었을 때, 관객들은 본인의 참여로 이야기의 흐름이 바뀌는 경험을 통해 상당한 만족감을 느꼈으며, 흥미로운 경험의 끝에 지구 온난화 문제를 자연스럽게 떠올릴 수 있었을 것이다. <북극곰 파오>의 메시지를 통해 사람들의 습관과 생각을 얼마나 변화시켰는지 당장은 알 수 없지만 이러한 시도를 통해서 애니메이션의 사회적 역할의 가능성을 엿볼 수 있는 계기가 되었다. 세계적으로 수많은 애니메이션이 제작되고 있다. 대부분 극장과 TV, 영화제를 목표로 제작되고 있는데, 조금 더 다양한 방법을 통해서 관객과 만날 수 있어야 한다. 그 중 하나가 바로 공공예술로서의 애니메이션이고, <북극곰 파오>는 그러한 의미에서 새로운 시도였다고 할 수 있다. 또한 앞으로 공공예술로서의 애니메이션은 우리가 함께 더불어 살 수 있는 생각을 공유하고 나눌 수 있는 흥미로운 경험을 선사하기 위해 노력해야 한다. 다양한 매체의 예술이 공익을 생각하는 예술로 바뀌어가고 있는 만큼 애니메이션도 다양한 테크놀로지와 융합하여 새로운 형태의 공공예술로 나아갈 수 있을 것이다.

Though the tradition of Korean mathematics since the ancient time up to the 'Enlightenment Period' in the late 19th century had been under the influence of the Chinese mathematics, it strove to develop its own independent of Chinese. However, the fact that it couldn't succeed to form the independent Korean mathematics in spite of many chances under the reign of Kings Sejong, Youngjo, and Joungjo was mainly due to the use of Chinese characters by Koreans. Han-gul (Korean characters) invented by King Sejong had not been used widely as it was called and despised Un-mun and Koreans still used Chinese characters as the only 'true letters' (Jin-suh). The correlation between characters and culture was such that, if Koreans used Han-gul as their official letters, we may have different picture of Korean mathematics. It is quite interesting to note that the mathematics in the 'Enlightenment Period' changed rather smoothly into the Western mathematics at the time when Han-gul was used officially with Chinese characters. In Koryo, the mathematics existed only as a part of the Confucian refinement, not as the object of sincere study. The mathematics in Koryo inherited that of the Unified Shilla without any remarkable development of its own, and the mathematicians were the Inner Officials isolated from the outside world who maintained their positions as specialists amid the turbulence of political changes. They formed a kind of Guild, their posts becoming patrimony. The mathematics in Koryo significant in that they paved the way for that of Chosun through a few books of mathematics such as 'Sanhak-Kyemong', 'Yanghwi-Sanpup' and 'Sangmyung-Sanpup'. King Sejong was quite phenomenal in his policy of promotion of mathematics. King himself was deeply interested in the study, createing an atmosphere in which all the high ranking officials and scholars highly valued mathematics. The sudden development of mathematic culture was mainly due to the personality and capacity of king who took anyone with the mathematic talent into government service regardless of his birth and against the strong opposition of the conservative officials. However, King's view of mathematics never resulted in the true development of mathematics perse and he used it only as an official technique in the tradition way. Korean mathematics in King Sejong's reign was based upon both the natural philosophy in China and the unique geo-political reality of Korean peninsula. The reason why the mathematic culture failed to develop continually against those social background was that the mathematicians were not allowed to play the vital role in that culture, they being only the instrument for the personality or politics of the king. While the learned scholar class sometimes played the important role for the development of the mathematic culture, they often as not became an adamant barrier to it. As the society in Chosun needed the function of mathematics acutely, the mathematicians formed the settled class called Jung-in (Middle-Man). Jung-in was a unique class in Chosun and we can't find its equivalent in China or Japan. These Jung-in mathematician officials lacked tendency to publish their study, since their society was strictly exclusive and their knowledge was very limited. Though they were relatively low class, these mathematicians played very important role in Chosun society. In 'Sil-Hak (the Practical Learning) period' which began in the late 16th century, especially in the reigns of Kings Youngjo and Jungjo, which was called the Renaissance of Chosun, the ambitious policy for the development of science and technology called for. the rapid increase of he number of such technocrats as mathematics, astronomy and medicine. Amid these social changes, the Jung-in mathematicians inevitably became quite ambitious and proud. They tried to explore deeply into mathematics perse beyond the narrow limit of knowledge required for their office. Thus, in this period the mathematics developed rapidly, undergoing very important changes. The characteristic features of the mathematics in this period were: Jung-in mathematicians' active study an publication, the mathematic studies by the renowned scholars of Sil-Hak, joint works by these two classes, their approach to the Western mathematics and their effort to develop Korean mathematics. Toward the 'Enlightenment Period' in the late 19th century, the Western mathematics experienced great difficulty to take its roots in the Peninsula which had been under the strong influence of Confucian ideology and traditional Korean mathematic system. However, with King Kojong's ordinance in 1895, the traditional Korean mathematics influenced by Chinese disappeared from the history of Korean mathematics, as the school system was hanged into the Western style and the Western mathematics was adopted as the only mathematics to be taught at the Schools of various levels. Thus the 'Enlightenment Period' is the period in which Korean mathematics shifted from Chinese into European.

세로토닌(serotonin, 5-HT)은 아민류 가운데 카테콜아민과 더불어 중요한 체네 생리 및 행동 조절을 담당하는 신경 전달물질이다. 특히 'Prozac'으로 잘 알려진 항우울제는 5-HT의 세포내 재흡수를 선택적으로 억제하는 약물(selective serotonin reuptake inhibitor, SSRI)로써 광범위하게 사용중인 약물인데, 알려진 부작용으로 사정 능력의 변화가 관찰된다. 이는 5-HT에 의한 성 행동 또는 성 기능 조절기작이 있음을 의미한다. 본 연구에서는 수컷 흰쥐의 성 행동 조절에 관여함이 잘 알려진 5-HT의 중추 신경계 수준에서의 작용 외에 말초 조직 수준에서 직접 작용이 가능한가의 여부를 검증하기 위해서 정소, 정관, 저정낭 등 수컷 흰쥐의 생식 기관들을 대상으로 5-HT 수용체 아형들의 유전자 발현 여부를 조사하였다. 적출된 뇌, 정소, 정관, 저정낭, 음경해면체 등의 장기에서 추출한 total RNA로 5-HT 수용체 각 아형들에 대한 RT-PCR을 시행한 결과, 대조군인 뇌는 물론 모든 생식 기관에서 다양한 5-HT수용체 아형들의 mRNA발현을 확인할 수 있었다. 특히 사정 반응을 담당하는 최종 장기인 저정낭과 정관에서, 지금까지 여러 연구 결과에서 사정 현상에 관여할 것으로 추정되어 온 5-H $T_{1A}$, 5-H $T_{1B}$, 5-H $T_{2C}$ 수용체 아형들이 실제로 발현됨을 관찰하였다. 이 결과는 5-HT에 의한 성 행동 조절이 중추신경계 수준에서는 물론 말초 조직 수준에서도 직접 가능함을 시사하는 것이다. 본 연구의 시도와 같이 5-HT의 다양한 작용기전에 대한 조사는 포유동물 성 행동에 대한 이해 증진과 더불어 성기능 이상의 부작용이 적은 새로운 항우울제의 개발로 연결될 수 있다고 판단된다.다.다.다.ized freezing방법간에 큰 차이가 없음을 볼 수 있었다.유의 경우 $World-Labs^(R)$ 처리구가 가장 높았다.상으로 면역활성 실험을 실시한 결과, 장관면역 활성은 젖산균의 세포질 획분에서 양성 대조군으로 사용한 LPS와 같은 수준의 면역활성을 나타내었고, 특히 Lb. acidophilus속 균주들의 세포벽 획분의 장관 면역활성이 다른 균주보다 높게 나타났다. 한편 젖산균주의 세포질과 세포벽 성분에 대한 비장 림프구의 증식능은 대조군과 비슷한 수준으로 낮게 관찰되었으나, 이들의 대식 세포증식능은 세포벽 및 세포질 모두의 획분에서 대조군보다 높았으며 특히 세포벽 획분의 경우에는 양성대조군인 LPS 보다 높거나 유사한 정도의 높은 활성을 확인할 수 있었다. 이상의 결과로부터 시험 균주 중에서 Lb. acidophilus 균주인 DDS-1과 B-3208이 프로바이오틱스로서 요구되는 조건을 충족시킨다는 것을 알 수 있었으며, 이들 균주의 상업적 이용 가능성을 재차 확인할 수 있었다./TEX>, 함량은 가공된 냉동감자보다 높은 것으로 나타났다. 상온 냉장저장 감자의 vitamin $B_1$, $B_2$ 함량은 각각 6, 4주차 이후부터 급격한 감소를 보였으나, 냉동저장 감자의 경우 48주(12개월)저장 중 함량변화가 없었다. 물성적 품질변화 평가에서 상온 냉장저장 감자의 무게와 부피는 24주간 다소 감소하는 경향을 보였으나 통계적인 유의차는 없었다. 냉동저장 감자의 무게와 부피 변화는 48주간 전혀 없었다. 상온 냉장저장 감자의 조직의 강도(hardness)는 24주간 다소 감소하는 경향을 보였으나 냉동저장 감자는 48주간 hardness의 변화가 전혀 없었다.

Operations research has developed rapidly since its origins in World War II. Practitioners of O. R. have contributed to almost every aspect of government and business. More recently, a number of operations researchers have turned their attention to library and information systems, and the author believes that significant research has resulted. It is the purpose of this essay to introduce the library audience to some of these accomplishments, to present some of the author's hypotheses on the subject of library management to which he belives O. R. has great potential, and to suggest some future research directions. Some problem areas in librianship where O. R. may play a part have been discussed and are summarized below. (1) Library location. It is usually necessary to make balance between accessibility and cost In location problems. Many mathematical methods are available for identifying the optimal locations once the balance between these two criteria has been decided. The major difficulties lie in relating cost to size and in taking future change into account when discriminating possible solutions. (2) Planning new facilities. Standard approaches to using mathematical models for simple investment decisions are well established. If the problem is one of choosing the most economical way of achieving a certain objective, one may compare th althenatives by using one of the discounted cash flow techniques. In other situations it may be necessary to use of cost-benefit approach. (3) Allocating library resources. In order to allocate the resources to best advantage the librarian needs to know how the effectiveness of the services he offers depends on the way he puts his resources. The O. R. approach to the problems is to construct a model representing effectiveness as a mathematical function of levels of different inputs(e.g., numbers of people in different jobs, acquisitions of different types, physical resources). (4) Long term planning. Resource allocation problems are generally concerned with up to one and a half years ahead. The longer term certainly offers both greater freedom of action and greater uncertainty. Thus it is difficult to generalize about long term planning problems. In other fields, however, O. R. has made a significant contribution to long range planning and it is likely to have one to make in librarianship as well. (5) Public relations. It is generally accepted that actual and potential users are too ignorant both of the range of library services provided and of how to make use of them. How should services be brought to the attention of potential users? The answer seems to lie in obtaining empirical evidence by controlled experiments in which a group of libraries participated. (6) Acquisition policy. In comparing alternative policies for acquisition of materials one needs to know the implications of each service which depends on the stock. Second is the relative importance to be ascribed to each service for each class of user. By reducing the level of the first, formal models will allow the librarian to concentrate his attention upon the value judgements which will be necessary for the second. (7) Loan policy. The approach to choosing between loan policies is much the same as the previous approach. (8) Manpower planning. For large library systems one should consider constructing models which will permit the skills necessary in the future with predictions of the skills that will be available, so as to allow informed decisions. (9) Management information system for libraries. A great deal of data can be available in libraries as a by-product of all recording activities. It is particularly tempting when procedures are computerized to make summary statistics available as a management information system. The values of information to particular decisions that may have to be taken future is best assessed in terms of a model of the relevant problem. (10) Management gaming. One of the most common uses of a management game is as a means of developing staff's to take decisions. The value of such exercises depends upon the validity of the computerized model. If the model were sufficiently simple to take the form of a mathematical equation, decision-makers would probably able to learn adequately from a graph. More complex situations require simulation models. (11) Diagnostics tools. Libraries are sufficiently complex systems that it would be useful to have available simple means of telling whether performance could be regarded as satisfactory which, if it could not, would also provide pointers to what was wrong. (12) Data banks. It would appear to be worth considering establishing a bank for certain types of data. It certain items on questionnaires were to take a standard form, a greater pool of data would de available for various analysis. (13) Effectiveness measures. The meaning of a library performance measure is not readily interpreted. Each measure must itself be assessed in relation to the corresponding measures for earlier periods of time and a standard measure that may be a corresponding measure in another library, the 'norm', the 'best practice', or user expectations.
