        Advanced POEMS syndrome treated with high-dose melphalan followed by autologous blood stem cell transplantation: a single-center experience

        장일영,윤덕현,김신,이경민,김광국,임영민,민원기,서철원 대한혈액학회 2014 Blood Research Vol.49 No.1

        Background POEMS syndrome is a rare paraneoplastic syndrome associated with plasma cell dyscrasia. High-dose chemotherapy followed by autologous stem cell transplantation has shown encouraging efficacy in the treatment of patients with POEMS syndrome. However, there are minimal reports on clinical outcomes after autologous stem cell transplantation for patients with advanced disease and very poor performance status. Methods We retrospectively evaluated 9 advanced POEMS syndrome patients, who had an Eastern Cooperative Oncology Group performance status score of 3 or 4, and were treated with high-dose melphalan therapy followed by autologous stem cell transplantation from 2004 to 2011. Results Eight patients achieved initial hematologic response, 4 of whom had complete responses. At a median follow-up of 44 months (range, 8‒94 months), 7 patients were alive, with 3-year overall survival rate of 77.8%. There were no hematologic relapses in the survivors. One patient died of disease progression; the other died of pneumonia despite a hematologic response 3 months after autologous stem cell transplantation. All survivors achieved improvement in general performance status and in clinical response. Conclusion High-dose melphalan followed by autologous stem cell transplantation can be considered a valid treatment option even for patients with advanced POEMS syndrome.

        현대조경설계에 있어서 시각 개념의 전개 양상 - 가시성에서 확장된 시각성을 중심으로 -

        장일영,김진선,Jang, Il-Young,Kim, Jin-Seon 한국조경학회 2006 韓國造景學會誌 Vol.34 No.4

        This study emphasizes users' participation, a living-transforming visuality, as users have appeared to be a central element of landscape design but ignored before. Also this study tries to propose meaning of extended visuality in contemporary landscape design on the basis of visual criticism on simple perception-and contemplations convention-based landscape design. For these purposes, this study reviews characteristics of visual changes appeared in modern reductionist paintings. In other words, arts can be interpreted in polysemous ways through bodies' experience. Deconstructive concepts derived from the theoretical reviews can be categorized into three including the participation of the users' bodies from a contemplative point of view, textuality and intertextuality, and experiences from works. Those concepts were used to criticize the previous discourse on landscape designs and to analyze various issues in the theories, themes and techniques in contemporary landscape design. The significance of the expanded visuality in contemporary landscape design is that it brings the users' voluntary participation. This structure can serve as a tool to obtain the users' perceptive effects. At the same time, it can be regarded as a process of establishing the relationships between the users and the works. Thus emphasis is placed not only on the influences of the effects structure of the works themselves, but also on the many different dimensions related to the users' bodies. It implies that the meaning of design is not determined by the designer but a product resulted from the voluntary relationships between users and works. These findings lead to ambiguous distinctions between arts everyday life, and eventually to the end of the concepts of formative dichotomous aesthetics and their effectiveness. Finding of this study call for not only redefining the space where landscape design is created and communicated, but also reconsidering the concepts of landscape design and its ontological meanings.

      • 국내의 실험자료를 이용한 고강도 및 초고강도 콘크리트의 탄성계수식 제안

        장일영,박훈규,윤영수 한국콘크리트학회 1996 콘크리트학회지 Vol.8 No.6

        최근 들어 고강도 및 초공강도 콘크리트의 사용이 국내외적으로 비약적인 증가 추세에 있으며, 국내에서도 이와 관련된 많은 연구가 진행되고 있다. 특히 재료개발 및 현장적용 측면에서의 연구가 활발하여 많은 성과를 얻어내고 있다. 그러나 설계단계부터 고강도의 콘크리트를 적용하는 참의미의 실용화 정도는 매우 미진한 실정이다. 이것은 설계단계부터 믿고 적용할 수 있는 고강도 콘크리트 관련의 국내 설계규준이 확립되어 있지 않은 것이 가장 큰 원인이 되고 있다. 따라서 본 연구에서는 고강도 및 초고강도 콘크리트 설계규준 정립에 있어서 기초적 자료가 될 수 있는 탄성계수의 추정식을 제안하였다. 이것은 국내에서 실험도니 고강도 및 초고강도 콘크리트의 탄성계수 값들을 근거로 통계적 수법을 이용한 것으로 압축강도 400-1,000kg/$\textrm{cm}^2$에 대해 적용할 수 있다. 또한 국외에서 발표된 탄성계수식을 국내의 실험값과 비교, 분석한 결과 전반적으로 과대평가하고 있음이 확인되어 본 연구에서 제안된 탄성계수 추정식이 국내실정에 적합할 것으로 사료된다. This paper presents the improved elastic modulus equation more appropriate to predict the modulus of elasticity of structural elements designed and made by high- and ultra high-strength concrete under domestic situation in Korea. To justify and assess the proposed elastic modulus equation, more than 400 laboratory test data domestically available in the literature and having the range of 400 to 1.000kg/$\textrm{cm}^2$ in concrete compressive strength were collected and analyzed statistically. Comparison of the proposed elastic modulus equation with the previously suggested equations in the ACI363R. CEB-FIP, NS3473 and New-RC were also presented to demonstrate the applicability to practice.

        교권침해 경험 초등교사의 심리적 소진과 회복과정

        장일영,기영화 인하대학교 교육연구소 2020 교육문화연구 Vol.26 No.3

        This study aims to understand how elementary school teachers respond to and recover from the experience of psychological burnout. For this purpose, data was collected through in-depth interviews of 8 elementary school teachers who experienced infringement of their teaching rights. The participants were interviewed using a semi-structured interview questionnaire until the intended sampling and saturation had been reached. Participants in the study were gathered in a snowball sampling method, through introduction by acquaintances. The data collected was subjected to continuous comparative analysis using Strauss and Corbin’s grounded theory methods. The analysis results were coded into 91 concepts, 30 subcategories, and 8 upper categories. The results of the study showed that causal conditions displayed ‘psychological burnout’, as the central phenomenon, through the ‘negative behavior of students’, ‘conflict with parents’, and ‘uninterested/indifferent teaching work culture’. Contextual conditions that imparted effects on these factors included ‘discrepancy between laws’, ‘teaching work culture’, ‘critical classroom environment’, and the ‘absence of a mediator’, while the intervening conditions were found to be in the category of the recovery process -including ‘support from surrounding people’, ‘affirmative interpretation’, ‘opportunity for expression of emotion‘ and ’dissipation of elements of civil complaint’- and the category of the worsening of burnout- including ‘lack of resources in the surroundings’, ‘psychological difficulties’, ‘continuous demand for civil complaint’, and ‘personal variables of teachers’. The ‘utilization of support resources’, ‘consolation by experience of sympathy’, ‘assertive efforts in problem-solving’, ‘efforts to improve specialization’, and ‘changes in the strategy of the teacher’ were deduced as the interaction strategy. The ensuing results included a manifestation of affirmative changes in the growth of the teachers such as ‘flexibility in thinking’, ‘foundation for a stable teaching profession’, and ‘attitude towards educational issues’, etc. However, the passion of the teachers towards education also decreased in the process. On the basis of aforementioned study results, proposals including systematic improvement of teacher’s authority, introduction of practical support system for protection of teacher’s authority, and means of restoration of trust between educational communities, etc. are made. 본 연구는 심리적 소진을 경험한 초등교사가 어떻게 반응하고 회복하는지를 이해하는 것을 목적으로 하였다. 이를위해 교권침해를 경험한 초등교사 8명을 대상으로 심층 면접하여 자료를 수집하였다. 참여자는 의도적 표집과 포화가될 때까지 반구조 인터뷰 질문지를 사용하여 인터뷰를 하였다. 연구참여자는 지인의 소개로 눈덩이 표집 방법으로이루어졌다. 이들 자료는 Strauss와 Corbin의 근거이론 방법을 사용하여 지속적으로 비교분석하였다. 분석결과 91개의개념과 30개의 하위범주, 8개의 상위 범주로 코딩하였다. 연구결과 인과적 조건은 ‘학생의 부정적 행태’, ‘학부모와의갈등’, ‘비관심/무관심 교직문화’를 통해 중심현상인 ‘심리적 소진’이 나타났다. 이에 영향을 미친 맥락적 조건은 ‘법간의 괴리’, ‘교직 문화’, ‘위기의 교실 환경’, ‘중재자의 부재’로 나타났고, 중재 조건은 ‘주변 사람들의 지원’, ‘긍정적해석’, 감정표현 기회‘, 민원 요소 사라짐’의 회복과정과 ‘주변 자원 부족’, ‘심리적 어려움’, ‘민원 지속적 요구’, ‘교사개인 변인’의 소진 심화 범주로 나타났다. 상호작용 전략은 ‘지지 자원 활용’, ‘동병상련 경험의 위안’, ‘적극적인해결 노력’, ‘전문성 향상 노력’, ‘교사의 전략변화’가 도출되었다. 그에 따른 결과는 교사의 ‘사고의 유연성’, ‘안정적교직생활 기반’, ‘교육 문제를 대하는 태도’ 등 교사 성장의 긍정적인 변화가 나타났다. 하지만, 그 과정에서 교육에대한 열정이 저하되기도 하였다. 이런 연구 결과를 바탕으로 교권의 제도적 개선, 교권보호를 위한 실질적 지원시스템 도입, 교육 공동체간 신뢰 회복 방안 등을 제안하였다.

        A Study on Formation Process and Modern Change in Japanese Tradition Skiya(数寄屋) - Centering on Ando Tadao's Work -

        장일영,김진선 한국전통조경학회 2010 한국전통조경학회지 Vol.8 No.-

        The purpose of this study is to grasp characteristics in Skiya(数寄屋), which are shown in his work, and further to understand its significance, through researching into Ando Tadao's work. Accordingly, this study aims to research into documentarily historical materials and a case work on how Skiya aesthetics, which is Japan's traditional aesthetic consciousness, was changed in Ando Tadao's work. Summarizing the findings, they are as follows. First, it is what the space of mental image is expressed poetically by metaphorically changing composition of a form through light, material, and geometrical composition, which are characteristics of Skiya that is traditionally aesthetic consciousness. In this way, as for Ando Tadao's work, the aim was to pursue the essence of the work by closely analyzing relationship between human beings and between a human being and nature and by analyzing it, through Skiya-based characteristics, not simple imitation on a form or a mode. In other words, it is the analysis on criticism for modern society and culture and on Japan's traditional concept. This is not what simply reflected only the traditional image or form, but what aims to contain spirit and sensitivity, which are included inside it. Second, what aimed to adopt aesthetic consciousness, which continuously emphasized combination with nature in Ando Tadao's work, can be said to have originated from intention of recovering the characteristics of Japan's traditional space, which is opened familiarly to the nature, in the lost space of modern society. He saw that a place where a human being and nature can meet each other is made inside a building. As for Ando, the light and wind come to finally have significance when they are adopted to the discontinued form from the external world, namely, to the inside of a work. In his work, Skiya aesthetics offers an important clue in grasping correlation between a human being and environment. To revive this aesthetics, it will be necessary to allow a work to be in sympathy with the environment, by employing spirit, not a physical form, and by creating a theory in new allness. Third, the emphasis of simplicity is expressed with succeeding to aesthetics of Japan's traditional Skiya. The composition of a form and space is expressed with excluding all the auxiliary things, observing on natural materials, forming simple form, and implementing empty space. Especially, the expression of emptiness in an inner court or of the exposed wall as if having peeled is well showing this spirit in Ando's work.
