  • William Wordsworth's "The Thorn" revolves around the following questions: Who is Martha? Why does she go to the mountain top and repeat her doleful cry? To these questions, it gives us two different kinds of answers; one derives from the villagers, and the other from the narrator. This essay attempts to examine how the answers exemplify two different critical approaches to the problem of community, using Jacques Lacan's account of sexual difference in his seminar on Encore as a guiding thread of analysis. The important thing to retain here is that sexual difference in Lacan's seminar on Encore does not so much indicate biological determinations as two distinct forms of relating to the other which are intimately bound up with the question of how a community is constructed and maintained. The first form, called "masculine," suggests that it is a radical exception to a community that makes possible the community as a field of totality or sameness; the second form, called "feminine," shows that each of the subjects cannot be regarded as a member of a closed community which is guaranteed by the exceptionality, but as an exception that is radically singular. This in turn leads us to consider the possibility that the masculine form has to do with the villagers' effort to distinguish themselves from Martha and the feminine form with the way in which the narrator confronts and represents her. In the course of his formulation of sexuation graph, Lacan stresses that the masculine side must be supplemented by the feminine side, which allows us to elaborate on why, concerning Martha, the narrator does not just keep the completely different position from the villagers'. This is to say that the villagers' representation of Martha as an exception to the community should be supplemented by the narrator's attempt to tell Martha's story as the villagers do and at the same time to capture something of her enigmatic unrepresentability. Bearing in mind Charles Shepherdson's elaboration of traumatic memory, this essay also tries to clarify how the narrator preserves and even transmits something of Martha's truth that is embodied in her uncontrollable and unassimilable cry.

  • 최근 사람과 기계의 소통을 위해 QA (Question Answering) 시스템에 대한 요구가 증가하였다. QA 시스템 중 공간에 관련된 질문을 처리할 수 있는 폐쇄 도메인 QA 시스템을 GeoQA라 하는데 본 연구는 GeoQA 분야에서 주로 사용되던 RDF (Resource Description Framework)기반의 데이터베이스가 데이터 입출력 및 변형에 한계를 보인다는 점을 극복하기 위해 최근 주목받고 있는 새로운 형태의 그래프 데이터베이스인 LPG (Labeled Property Graph)를 사용하였다. 또한, LPG 쿼리(query)언어가 표준화되지 않아 GeoQA 시스템이 특정 제품에 의존할 수 있다는 점 때문에 API 형태의 쿼리 언어인 GraphQL (Graph Query Language)을 도입하여 다양한 LPG를 사용할 방안을 제시하였다. 본 연구에서는 공간 관련 질문이 입력되었을 때 답변을 검색할 수 있도록 대한민국 중심의 별도 데이터베이스를 구축하였는데 각 데이터는 국가공간정보포털 및 지방행정 인허가데이터개방 서비스에서 취득하였으며 각 공간 객체 간 공간적 관계는 미리 계산되어 그래프의 엣지(edge) 형태로 입력되었다. 사용자의 질문은 먼저 FOL (First Order Logic)형태를 거쳐 최종적으로 GraphQL로 변환되며 GraphQL 서버를 통해 데이터베이스에 전달되었다. 실험에 사용한 LPG로는 현재 가장 높은 점유율을 보이는 그래프 데이터베이스인 Neo4j를 선택하였고 내장 함수와 QGIS 일부가 공간 연산에 사용되었다. 시스템 구축 결과 사용자의 질문을 변환, Apollo GraphQL 서버를 통해 처리하고 데이터베이스로부터 적합한 답변을 얻을 수 있음을 확인하였다.

  • Purpose: The purpose of the study was to conduct a descriptive survey to examine the knowledge, infection prevention behaviors, and health beliefs regarding COVID-19 and to identify factors that influence infection prevention behaviors in elementary and middle school students based on the Health Belief Model. Methods: The study included 388 elementary and middle school students in Seoul, Gyeonggi, and Jeonbuk provinces. Data were collected from September 1 to September 15, 2023. The questionnaire consisted of 10 questions about COVID-19 knowledge, 13 questions about infection prevention behaviors, and 15 questions about health beliefs. The collected data were subjected to multiple hierarchical regression analyses. The cronbach's α of infection prevention behaviors was 0.83, the KR-20 of COVID-19 related knowledge was 0.68, and the Cronbach's α of COVID-19 related health beliefs was 0. 78. Results: In Model 1, females showed higher levels of infection prevention behaviors than males (β=.14, p=.006) and middle school students showed lower levels of infection prevention behaviors than elementary school students (β=-.10, p=.037). In Model 2, among COVID-19-related health beliefs, barriers had a significant negative effect on infection prevention behaviors (β=-.20, p<.001) and cues to action had a significant positive effect on infection prevention behaviors (β=.14, p=.037), indicating that lower barriers and higher cues to action were associated with higher levels of infection prevention behaviors. Conclusion: The results showed that prevention behaviors were associated with lower barriers and higher cues to action among COVID-19 health beliefs. Elementary and middle school students in Korea spend a lot of time in groups at private academies or school, which are closed spaces with poor ventilation, making them vulnerable to new infectious diseases such as COVID-19. Unlike adults, infectious diseases can have serious impact on their mental and social health. Therefore, it is necessary for schools to provide accurate and timely health education about COVID-19 to increase cues to action for elementary and middle school students in order to improve their infection prevention behaviors.

  • The expansion of media art has not only developed the digital technology but also given lots of environmental evolution to improve various fields of design as the main topic of the 21st century. The purpose of this study is aimed at proposing the new design that integrates fashion accessaries with media art technology. This will be done by understanding the social environment in digital ages and studying technology of design based on a variety of literature about changes in our society, neo value, vision, culture and art with fundamental notion of media art. First stage for this study, put an idea into just fashion accessary design because it is not sufficient to incoporate fashion and media art technology. The presented OLED(Organic Light Emitting Diodes) in this study is a kind of display to be in a limelight in the next generation and can be applied to various field of design. media art simultaneously moved into the scope of artistic debates. As a result, we can found that the use of audiovisual introduced numerous new aspects to the conceptual and aesthetic engagement with questions of conception. Today, the presented forms of art and inter-action from the closed -circuit work to interactive media art installations to open process-exist as parallel possibilities.

  • Recently, Choe & Cheng (2002) have demonstrated that multiple magnetic flux systems with closed configurations can have more magnetic energy than the corresponding open magnetic fields. In relation to this issue, we have addressed two questions: (1) how much fraction of eruptive solar active regions shows multiple flux system features, and (2) what winding angle could be an eruption threshold. For this investigation, we have taken a sample of 105 front-side halo CMEs, which occurred from 1996 to 2001, and whose source regions were located near the disk center, for which magnetic polarities in SOHO/MDI magnetograms are clearly discernible. Examining their soft X-ray images taken by Yohkoh SXT in pre-eruption stages, we have classified these events into two groups: multiple flux system events and single flux system events. It is found that 74% (78/105) of the sample events show multiple flux system features. Comparing the field configuration of an active region with a numerical model, we have also found that the winding angle of the eruptive flux system is slightly above $1.5{\pi}$.

  • The purpose of this study was to compare dietary culture consciousness of rural and urban housewives through a nationwide survey. Interviewers interviewed 500 housewives(250 in rural and 250 in urban) using closed-ended questions. The dietary culture consciousness was divided into two parts of traditional aspect (dietary habit and ritual diet) and desirable aspect (food choice and nutrition knowledge). Each domain consisted of six items. Results of the study are summarized as fellows : 1) As a whole, dietary culture consciousness of rural housewives was more traditional than that of urban housewives in traditional aspect, and there was no difference of consciousness between rural and urban housewives in desirable aspect. 2) There was significant difference at 1% level between two groups in traditional aspect and there was no difference in desirable aspect. 3) By the analysis of each item, there was significant difference between two groups in 14 items. Especially, the item of westernized breakfast pattern was more acceptable in urban housewives than in rural. 4) In relationship between socio-demographic characteristics of housewives and dietary consciousness of them, age, educational level and religion of housewife were significant in traditional aspect, and so were educational level and job experience of housewives in desirable aspect. Dietary consciousness of rural housewives' was influenced by job experience (in traditional aspect) and age of housewives and level of living (in desirable aspect) In the case of urban housewives, level of living was significant in traditional aspect.

  • This paper identifies five factors that limited urban network formation in Northeast Asia over the past half millennium, questions the extent to which they are being overcome in the 1990s, and sketches a network of cities that could boost regionalism. It briefly traces the historical evolution of these factors, including comparisons with European integration, while focusing primarily on the policies of the 1990s that have affected their continuing role. First is the factor of closed national markets with weak regional integration. Second is the preeminence of administrative means of integration over commercial ones. Third is the character of localism, shackled by overcentralization and weak cross-border linkages. Fourth is the limited nature of internationalism, dominated by state catch-up policies with one-sided global involvement. Fifth is a lack of regional consciousness. Just as national urban integration was essential for regional networks to form, without regional integration it is difficult to contemplate Northeast Asian cities taking their rightful place in a global urban network. After noting the failures of the 1990s, the paper points to the potential role as dragon's heads for sub-regional urban networks of potential front-line cities: Tumen, Sapporo, Irkutsk, and what I call the Amur triangle. Also of interest are how the capitals of Beijing, Moscow, Seoul, and Tokyo will adjust to a transformed urban network. After all, their current skepticism must be overcome with a program that links the benefits on all sides in order to build trust in regionalism. This requires internationalism and symbols of a balanced approach to each country's needs.
