  • 목 적 : 실신은 소아에서 가장 흔한 증상이지만 기전은 잘 알려져 있지 않다. 증가된 미주신경의 활동과 감소된 교감신경의 자극이 저혈압, 서맥을 일으키고 마침내는 의식 소실을 초래한다. 이 연구의 목적은 혈관미주 신경성 실신으로 진단된 소아에서 기립경사 검사를 하는 동안 뇌 도플러 초음파를 실시하여 실신 전후의 뇌혈류 속도와 혈압, 심박동수 변화를 측정하고자 하였다. 방 법 : 실신의 과거력을 갖고 있는 64명의 소아를 대상으로 혈압을 10분간 안정 후와 15분 동안 기립 후에 측정하였고, 기립 경사 검사는 $80^{\circ}$에서 45분간 시행하였다. $80^{\circ}$ 각도의 경사 테이블에서 소아를 5분 간격으로 45분 동안 혈압, 심박동수, 산소 포화도를 측정하였다. 기립경사 검사를 하는 동안 실신이나 실신 전 증상이 나타난 소아에서는 검사를 중단하였다. 12-유도 심전도, 뇌파 검사, 심장 초음파를 시행하였다. 기립경사 검사에서 양성으로 나온 10명의 소아에서 Acouson 128XP/10 model 초음파 기기를 이용하여 중 대뇌동맥 혈류 속도, pulsatility 지수, time velocity integral, 혈압, 심박동수, 산소포화도 등을 측정하였다. 결 과 : 기립경사 검사에서 31.3%(20/64)의 양성률을 보였다. 검사 동안에 혈압과 맥박은 감소되지 않았고 뇌혈류 속도와 integral은 유의하게 감소되었다. 결 론: 뇌혈류 속도는 혈압이나 심박동수가 감소하기 전에 미리 감소하므로 실신 전 증상을 미리 예측할 수 있다. 뇌혈류의 자율 조절의 장애가 혈관미주 신경성 실신의 병인론에 중요한 역할을 하리라 생각된다.

  • 본 연구의 목적은 GI-STEAM 모형에 기반하여 개발된 영재 프로그램이 초등영재의 리더십과 창의적 인성, 학습몰입에 미치는 영향을 검증하는 데 있다. GI-STEAM 수업모형은 협동학습 모형 중 집단탐구 모형(Group Investigation)과 STEAM 학습준거틀을 융합한 모형을 말한다. 연구참여자는 경기도 소재 Y시 초등학교 6학년 영재학급 학생 16명이며, 리더십, 창의적 인성, 학습몰입에 대한 사전검사를 실시하였다. 이후 GI-STEAM 프로그램 12차시를 적용한 후 리더십, 창의적 인성, 학습몰입에 대한 사후검사를 실시하였고, 프로그램에 대한 소감문 및 개별면담을 실시하였다. 사전-사후검사 결과를 대응표본 t-검정을 통하여 분석한 결과는 다음과 같다. 첫째, GI-STEAM 프로그램은 리더십의 개인 간 영역을 유의미하게 높여주는 것으로 나타났다. 하위영역으로는 의사표현, 조직관리 영역, 사회헌신, 팀워크에서 유의미한 향상이 나타났다. 둘째, GI-STEAM 프로그램은 창의적 인성영역에 있어서 유의미한 차이가 나타나지 않았고, 하위영역 중 심미성 영역에서 유의미한 향상이 나타났다. 셋째, GI-STEAM 프로그램은 학습몰입에 있어서 유의미한 향상을 보였다. 하위영역에서는 도전과 능력의 조화, 행위와 의식의 통합, 구체적인 피드백, 자기목적적 경험에서 유의미한 향상이 나타났다. GI-STEAM 프로그램은 교육부에서 제시한 2015 개정교육과정의 '창의융합형' 인재의 핵심역량 중 의사소통 역량, 심미적 감성역량, 공동체 역량 등을 기르는 데 효과적임을 알 수 있으므로, GI-STEAM 모형을 활용한 다양한 프로그램을 개발하여 교육현장에 제공할 필요가 있다고 판단된다.

  • After the development of printing technology since the 15th century and the rise of citizen consciousness in the 18th century, the library has taken a public concept. And after the 20th century, its role as a public library for the public was stressed, and as its spatial composition became miniaturized and specialized, its function changed from stacking and reading to various kinds including culture and service and is getting more complex beside the function of a library. Thereupon, this study aims to figure out the limitations of public libraries' opening years shown in advanced researches and understand the current status of spatial composition by complexation with the subjects of five public libraries opened after the end of December, 2006 in order to examine their tendencies of complexation and the characteristics of spatial composition by the complexation of public libraries. As a result, the present public libraries have at leaser more than two spaces with complex functions. According to the result of analysis on the types, locational relations between spaces showed the mixed type the most. In the types of building allocation, the building integrated type had a higher percentage than the separated type. About the types of entrance, the one common door type was fewer than the two separate door type. In the analysis on the types of the interior line of flow, the common type was similar to the dispersed type, and it is thought to be resulted from spatial composition rather than the preplanned line of flow.

  • This study suggests a fashion design using aesthetic characteristics of works by Kate MccGwire, a modern sculptor paying attention to soft sculpture materials such as feathers. In this research on MccGwire works, their internal meanings may be derived as the dualism of familiarity, movement and consciousness. Works also have aesthetic characteristics of overlapping, fluidity and twist. Using such characteristics, 4 one piece dresses and 2 vest dresses were made. Research findings are as follows. First, aesthetic characteristics of MccGwire works could be expanded into expressive areas of silhouettes and details in fashion. Second, visual flow and concentration could be expressed by gradual coloration of feather colors. Third, dart manipulation could be applied naturally by details and curve silhouettes of fashion design. Fourth, touch of feather material could be expressed fully by leaving the edge of garments raw. Fifth, spatiality of fashion could be implemented partially by applying decorative saddle stitching to costume design details. This study explored a potential of soft sculpture occurred during a transitional process of objet pursued by 20th century's avant-garde artists applicable to fashion design ideas that suggested methods for contemporary creative design.

  • Oculomotor nerve palsy (ONP) with subarachnoid hemorrhage (SAH) occurs usually when oculomotor nerve is compressed by growing or budding of posterior communicating artery (PcoA) aneurysm. Midbrain injury, increased intracranial pressure (lCP), or uncal herniation may also cause it. We report herein a rare case of ONP associated with SAH which was caused by middle cerebral artery (MCA) bifurcation aneurysm rupture. A 58-year-old woman with clear consciousness suffered from headache and sudden onset of unilateral ONP. Computed tomography showed SAH caused by the rupture of MCA aneurysm. The unilateral ONP was not associated with midbrain injury, increased ICP, or uncal herniation. The patient was treated with coil embolization, and the signs of oculomotor nerve palsy completely resolved after a few days. We suggest that bloody jet flow from the rupture of distant aneurysm other than PcoA aneurysm may also be considered as a cause of sudden unilateral ONP in patients with SAH.

  • The death scenes are the culmination of both Doris Lessing's "To Room Nineteen" and Toni Morrison's Sula. Lessing's Susan, an intelligent white English woman, gradually loses the meaning of life as awealthy housewife in the patriarchal society and commits suicide as her solution in Room Nineteen of Fred's Hotel. Morrison's Sula, an African-American woman, grows up without having the normal ego under Eva's matriarchy in a black community named the Bottom. Sula, after Nel's marriage, becomes a symbol of evil to her community and drifts down to death in Eva's bed. Reading these two death stories from the perspective of Jung's archetypal psychology, Susan is not able to continue to live a meaningful life because her life energy is cut off from its source which is in the unconscious. According to Jung, the symbol is the medium of the psychic energy from the unconscious to consciousness. In modern society which is represented by intelligence, the religious and mythical symbols are removed by rationalism, which means disconnection of the flow of life energy from the unconscious. Susan's death can be read as a kind of creating symbol to connect the modern people to the source of life energy. Sula's case is the opposite of Susan's. She remains in the unconscious world without having the proper ego in the absurd reality of racial and sexual problems. Sula finally rises again in Nel's awareness, becoming a symbol of the feminine goddess like goddess Inanna.

  • This study aims to focus on clothing design's practical uses of the superior esthetic elements that can be found among the East's representations, in particular the characteristic Korean elements found in the latter part of the Chosun Era's women's Gauche and decorative personal ornamentation's moulded features. This has been the foundation for the creation of all eight pieces, and the conclusion is as follows: First of all, the Chosun Dynasty women's Gauche and ornamentation are in close relation to the general flow of society at the time. Gauche and personal ornamentation was not just a matter of beauty consciousness, but is permeated with then-mainstream society's culture, the results of an attempt to display a Korean appearance. Secondly, the desirability of the Chosun women's hair was expressed through Gauche, and through the exceptional brilliance of a diversity of embroidered color tones, braided as though creating Dare. Using this technique in clothing, a new image was created. Thirdly, the outstanding beauty of personal ornamentation's mouldings was used while creating new clothing compositions. The beauty felt through the Chosun women's personal ornamentation can also be felt through today's clothing. More than merely practical, this beauty also brings one closer to Korea and Korean past.

  • The treatment of bilateral vertebral artery dissecting aneurysms (VADAs) presenting with subarachnoid hemorrhage (SAH) is still challenging. The authors report a rare case of bilateral VADA treated with coil trapping of ruptured VADA and covered stents implantation after multiple unsuccessful stent assisted coiling of the contralateral unruptured VADA. A 44-year-old woman was admitted to our hospital because of severe headache and sudden stuporous consciousness. Brain CT showed thick SAH and intraventricular hemorrhage. Cerebral angiography demonstrated bilateral VADA. Based on the SAH pattern and aneurysm configurations, the right VADA was considered ruptured. This was trapped with endovascular coils without difficulty. One month later, the contralateral unruptured VADA was protected using a stent-within-a-stent technique, but marked enlargement of the left VADA was detected by 8-months follow-up angiography. Subsequently two times coil packing for pseudosacs resulted in near complete occlusion of left VADA. However, it continued to grow. Covered stents graft below the posterior inferior cerebellar artery (PICA) origin and a coronary stent implantation across the origin of the PICA resulted in near complete obliteration of the VADA. Covered stent graft can be used as a last therapeutic option for the management of VADA, which requires absolute preservation of VA flow.

  • This study identifies visible/invisible factors and analyzes facilities, structure, and visible perceptive contents in the aspects of operation and efficiency with a focus on the interfaces between interior design of the subway and users. More specifically, it diagnoses the requirements and empirically presents improvements. In addition, this study aims to diagnose the interfaces between trains and users by reinterpreting and evaluating factors from the perspectives of users, and to elicit the universal interface and an objective form of conceptual, structural, and formative relations in regard to the conditions required to the design. As the interior design in the subway trains is for the public reflecting the value, consciousness, and behaviors of users, it should be approached through the application of the concept of universal design that considers the potential needs and psychological satisfaction of users. In arranging the indoor of the vehicles, the conditions for the facilities should be specified through the interdisciplinary approach from professional fields including ergonomics and psychology, the path of flow should be induced through the use of space and the analysis of passengers' behaviors, an integrated planning should be re-established, and continuous evaluations of basic guidelines, manuals, and requirements should be made.
