무선통신망과 GPS(Global Positioning System)를 탑재한 모바일 단말기의 발달로 사람이나 사물의 위치정보를 파악하고 이용하는 위치기반 서비스의 영역이 확대되고 있다. 위치기반서비스와 같은 응용분야에서는 시간에 따라 연속적으로 움직이는 이동객체를 효율적으로 저장하고 처리할 수 있는 데이터베이스가 주요한 기술이다. 본 논문에서는 이동객체 데이터베이스를 개발하기 위한 하나의 서브시스템으로서, 이동객체에 대한 질의를 처리하기 위한 컴포넌트를 설계 및 개발한다. 이동객체에 대한 질의를 처리하기 위해서 대표적인 질의표현 및 처리방법을 조사하고, 기존에 개발된 이동객체에 대한 데이터모델과 연산자를 기반으로 SQL형태의 이동객체 질의어를 새로이 정의한다. 사용자는 본 연구에서 제공하는 이동객체 질의어를 이용하여 이동객체의 위치정보에 대한 영역질의, 위상질의, 궤적질의, 최근접질의 등을 표현할 수 있다. 이동객체 질의처리 컴포넌트는 각 질의 들을 분석한 후 이를 효율적으로 처리하기 위한 모듈들을 설계하고 구현한다. 또한, 다른 이동객체 응용시스템을 개발할 때 본 시스템의 활용을 높일 수 있도록 ADO.NET 인터페이스를 제공하고 XML을 이용하여 질의의 결과를 표현할 수 있는 기능을 제공한다. With the growth of wireless communication networks and mobile devices taking in GPS, Location-Based Service(LBS) is becoming an integral part of mobile applications. LBS can deal with location-aware features such as persons holding mobile phones or vehicles equipped with GPS, and provide the users with the location information of the features. Thus it is necessary to develop moving object database systems to store, manage, and query moving objects which change their locations continuously as time passes. In this paper, we design and implement a query processing component which deals with moving objects as a key data type. For this component, we define a new SQL-like query language(called MOQL) and as a consequence, design and implement modules that analyze and execute queries. It supports various types of operators that process range queries, infer topological relations, compute trajectories, and find k-nearest neighbors. It can be used as a subsystem if other application systems which deal moving objects and also supports ADO.NET interface that can be used to interact end-users.

도로 위에 존재하는 이동객체의 궤적에 대한 네트워크 기반의 색인 방법

김경숙,이기준,Kim, Kyoung-Sook,Li, Ki-Joune 한국정보처리학회 2006 정보처리학회논문지D Vol.13 No.7

최근 많은 연구들이 유클리디안 공간을 기반으로 대용량의 이동객체 궤적 데이터를 효율적으로 다루기 위해 진행되어 왔다. 그러나, 일반적으로 실제 응용분야에서는 이동객체가 움직일 수 있는 공간은 제한적이다. 예를 들어, 도로 위에 존재하는 자동차들은 서로 연결된 도로망을 통해서만 이동할 수 있다. 본 논문에서는 도로 위의 이동객체 궤적에 대하여 시공간 영역 질의를 처리할 수 있는 네트워크 기반의 색인방법을 제안한다. 제안된 방법은 질의 처리 과정에서 네트워크 상의 거리를 이용하기 위해서 도로 네트워크의 연결정보를 색인구조에 포함한다. 그리고, 이동객체의 위치 정보를 도로를 구성하는 도로 선분요소 정보를 이용하여 표현하고 이를 단위로 여러 개의 R-tree를 사용하여 이동객체 궤적들을 관리한다. 또한, 여러 개의 도로 선분요소 사이에 하나의 R-tree를 공유할 수 있는 구조를 가짐으로써, 큰 도로 네트워크 데이터에서도 적용할 수 있다. 우리는 실험을 통해서 네트워크 거리를 기반으로 시공간 영역질의를 처리하는 것은 기존의 유클리디안 거리 기반의 방법들 보다 대략 30%의 성능향상을 보임을 보여준다. Recently many researchers have focused on management of Historical trajectories of moving objects in Euclidean spaces due to numerous sizes of accumulated data over time. However, the movement of moving objects in real applications generally has some constraints, for example vehicles on roads can only travel along connected road networks. In this paper, we propose an indexing method for trajectories of moving objects on road networks in order to process the network-based spatiotemporal range query. Our method contains the connect information of road networks to use the network distance for query processing, deals with trajectories which are represented by road segments in road networks, and manages them using multiple R-trees assigned per each road segment. Furthermore, it has a structure to be able to share R-tree among several road segments in large road networks. Consequently, we show that our method takes about 30% less in node accesses for the network-based spatiotemporal range query processing than other methods based on the Euclidean distance by experiments.

The results of analysis on perceptions of residential facilities for the elderly are as follows. First, all respondents demonstrated a preference for apartment-style residential housing even after retirement. Second, respondents showed a preference toward living in Seoul/the metropolitan area or in a nearby rural area, indicating a desire to reside independently in close proximity to their children. Third, most respondents showed a preference for rural housing, while female respondents demonstrated a preference for apartments. Fourth, it was shown that larger floor area of current apartment correlated with a preference toward residing in Seoul/metropolitan area. Fifth, it was shown that those presently residing in apartments desired to maintain an independent residence close to their children. Sixth, female respondents over the age of 60 had the greatest level of interest in elderly residential facilities, while those between 51-60 showed the most inclination to relocate to such a facility. Seventh, it was found that the ideal personal living space for elderly residential facilities was less than 11-15 pyeong (3.3 m2).

Hedera rhombea (HR) has been used for treatments of hemorrage, chronic catarrh, jaundice, lithisis and convulsion. This study was done to isolate active compounds that have protective effect on liver damage. BuOH and EtOAc fractions of HR recovered serum glutamic pyruvic transaminase (GPT), glutamic oxaloacetic transaminase (GOT) and gamma-glutamyltranspeptidase (gamma-GTP) activities in CCl4 treated rats. We isolated 7 phenolic compounds from BuOH and EtOAc fractions, which were identified as 3-caffeoyl quinic acid, 3,4-di-O-caffeoyl quinic acid, 3,4-di-O-caffeoly quinic acid, 4, 5-di-O-caffeoyl quinic acid by chemical and spectral analysis. These compounds reduced significantly serum GOT and GPT elevated by CCl4 treatment in rats, and 3-caffeoyl quinic acid, 3,5-di-O-caffeoyl quinic acid and caffeic acid also showed mild inhibitory activity against human immunodeficiency virus.

포도주, 광기 그리고 나쁜 피 -『제인 에어』속 제국주의 다시 읽기

김경숙 ( Kyoung Sook Kim ) 한국영어영문학회 2011 영어 영문학 Vol.57 No.2

Charlotte Bronte`s novel Jane Eyre has long been doted on as one of the canonized texts of British literature since its publication. Seemingly, this romantic novel has nothing to do with plantation based on slave trade. However, paying a keen attention to the fact that Jane`s enormous inheritance results from wine plantation at a colony, this essay re-interprets Bertha`s drinking and madness as evidence of imperialism. For the porter/jin Bertha and Grace Poole enjoy might have some suspicious connection with wine, the very root of Jane`s great expectations. Jean Ryes` Wide Sargasso Sea, writing Jane Eyre back, records Bertha as "a white resident of the West Indies, a colonizer of European descent" (326). However, Jane Eyre, in my interpretation, describes Bertha pretty much as a black Creole. At any rate, the view that the white West Indians are tainted by miscegenation proves contemporary racism and is reflected in the text through Bertha and her mother`s intemperate drinking and madness. Drinking and madness are stigmatized as the evidence of the so-called "bad blood"; embodying the stereotypes of drinking, madness, and sexual corruption, Creoles, the very inescapable product of imperialism, provide a convenient excuse for justifying imperialism for purity, civilization, and moral cleanness. In this way, Jane Eyre needs to be re-interpreted politically and historically in the context of colonialism. British imperialism pursues a tremendous amount of profits through grape plantation and wine trades; however, it cleverly leaves in the colony the associated images such as intemperate drinking and madness. Bertha, transferred from Jamaica to Britain, takes in these negative images of "savageness." Transcending the narrow confines of feminist criticism obsessed with doubling between Bertha and Jane, this essay, accordingly, reads Bertha the prisoner in the attic as the captive for perpetuating imperialism. This reading hinges upon interpreting Rochester and St John as colonizers bearing the socalled "white men`s burden" to cultivate and civilize savages much like crops such as grapes and sugarcane in the colonial plantation.

『사상계』 게재 희곡에 재현된 가족담론과 가족해체양상 - 한로단의 「교류」, 「가족」중심으로

김경숙(Kim, Kyoung-sook) 전남대학교 한국어문학연구소 2021 전남대학교 한국어문학연구소 학술지 어문논총 Vol.0 No.38

이 연구는 전후 한국의 사회상을 이해하기 위한 작업의 하나로 문학(희곡)에 재현된 1950∼60년대 사회담론과 전통적 가족 문화의 해체 양상(이하 가족해체 양상)을 살펴본 것이다. 당대의 지식인들이 생산했던 가족담론을 우선적으로 살펴본 결과 가족정책과 가족윤리에 관한 비판적 담론이 문학에 재현된 흥미로운 양상을 확인하였다. 당시 국가주도의 가족정책은 전후재건을 위한 선전의 도구로써 전형적인 건전가족, 명랑가족에 대한 홍보에 치중하고 있었다. 하지만 문학에 재현된 가족양상은 해체와 파국의 모습이 많았다. 특히 『사상계』가 게재한 희곡에 그려진 가족양상의 대부분이 이 특성을 띠는데 같은 극 장르이지만 1960년대 영화가 유쾌한 가족(명랑가족)의 모습을 주로 그린 것과는 변별되는 지점이다. 이것은 국가 정책에 관한 당대 지식인들의 우회적인 비판의식의 작용, 즉 ‘문학을 통한 비판’으로 해석된다. 이 연구는 한로단의 「교류」와 「가족」을 중심으로 이 시기의 실제 사회와 정부의 가족정책 선전 간의 괴리가 문학(희곡)에서 어떤 모습으로 재현되는지 살펴본 것이다. 본 논문은 『사상계』의 가족담론과 희곡서사를 통해 근대화의 일환이었던 가족정책의 모순을 확인해봄으로써, 전후 한국을 이해하는 또 하나의 시각을 제시하고자 한다. This study looked at social discourse and family aspects from the 1950s and 1960s, which were reproduced in literature (plays) as part of an effort to understand the social situation of postwar Korea. The family discourse produced by intellectuals through 『Sasanggye』, which was a representative public forum of the time. As a result of the study, the discourse produced by the 『Sasanggye』 on family policies and family ethics confirmed that there was an interesting aspect of reproducing political opinions into literature. At that time, the government-led family policy was focused on promoting healthy and cheerful family-stereotypes as a tool of propaganda for postwar reconstruction. However,the family aspect reproduced in literature showed many signs of dissolution and catastrophe. In particular, most of the family aspects depicted in the plays published by “Sasanggye” are characterized by division and dissolution. This is a distinctive ;point from the 1960s movies, which are the same genre of theater, mainly portraying pleasant family members. This study interpreted the family aspect of the play published by “Sasanggye” as an indirect criticism from intellectuals. In other words, it is a ‘criticism through literature’ to of the political circle at the time, which tried to hide 01darker social aspects while promoting growth and development through the policy of modernization. 「Gyolyu」and 「Gajog」of the Hanrodan was an interesting work to look at to study how the actual gap between real society and government-led family propaganda of this period is reproduced in plays.

Beyond the Binary Opposition of Poetics and Politics: Shelley"s The Mask of Anarchy

Kyoung-sook Kim(김경숙) 한국영미어문학회 2007 영미어문학 Vol.- No.82

  This essay intends to provide a political re­reading of Shelley’s poetry as a political discourse and his politics as a poetic discourse, focusing on The Mask of Anarchy in terms of the politics of poetic form. In short, this article argues that poetics and politics are one in Shelley, at least in The Mask. While the first half of The Mask shows how to read written history as a disguised masquerade, the other half is concerned with how to write unwritten history through poetry. On the one hand, by re-presenting the Peterloo Massacre as a dream vision of the poet, Shelley sheds a new light on the massacre and, at the same time, calls for the audience’s active interpretation of the event in this unfamiliar version. Besides, the incoherent and not­seamless structure of The Mask also heightens the “alienation effect” of the poem, impeding the audience’s entire immersion into the poem. Shelley’s representation of the massacre as a masquerade asks readers to “read” not only his poem but also the massacre itself with a keen sense of political consciousness.<BR>  In The Mask, more importantly, history itself becomes a kind of text to be read, written, and revised like a poem; the poem is a kind of political performance to intervene in society like political movements. Like Poesy  awakens and inspires the poet, Shelley wants his poem to awaken and inspire the reformers so that they can “revise” their previous drafts of law. Through The Mask, in short, Shelley shows how to read/write a poem and, at the same time, how to read/write history as a story. After all, poetics and politics become one in Shelley.
