모성회귀 체험에 관한 존재론적 탐구

최은우 한국미술치료학회 2016 美術治療硏究 Vol.23 No.1

This study inquired into the nature of the experience during in the self-healing period in regression from our realistic life during the psychological process of maternal regression and the effect of maternal regression on life. The researcher carried out the research ontologically on the maternal regression activities, targeting 8 middle-aged office workers residing in a big city and having their children. As a result, total 40 stories were found in total on the maternal regression of the participants. The meaning of the maternal regression experience is summarized as follows: First, 'coloring the shadows in the mind with the form of one's life', Second, 'healing process transcending the life'. The former includes 'regaining something suppressed in the realistic life', 'escaping difficult circumstances and staying in one's body' and 'an existence-based aesthetic experience'. The latter includes 'creating a bridge for living as the existence of myself', 'staying in the space of déjàvu', 'being held in the arms of a mother in me', 'entering a loop of circulation' and 'being held in liveliness of life'. Hereby, it is shown that the maternal regression has existential meaning and that it can be applied to art therapy to achieve an integration of the universality and the uniqueness of a human as well as the paradoxical contents of life as an active activity based on the physicality of an individual. 본 연구는 우리가 모성회귀의 심리적 과정에서 현실적인 삶으로부터 퇴행하여 자기치유의 시간에 존재하는그 체험의 본질은 무엇이며, 모성회귀 체험이 우리 삶에서 어떤 의미로 드러나는지를 해명하는데 목적을 둔다. 이에 연구자는 대도시에 거주하면서 자녀를 둔 중년 직장인 8명을 대상으로 8개월 동안 그들의 모성회귀 활동을 존재론적인 탐구로 진행하였다. 그 결과 참여자들의 모성회귀는 그들의 삶과 관련하여 전체 40개의 스토리가 생성되었다. 이러한 과정에서 발굴한 모성회귀 체험의 의미는 첫째, ‘마음의 그림자를 삶의 형식으로 채색하는 일’ 둘째, ‘삶이 초월되는 치유 과정’으로 요약된다. 첫 번째 의미는 ‘현실로부터 억압되었던 것을 되찾는일’, ‘어려운 현실로부터 벗어나 자신의 신체성에 머무는 일’, ‘실존에 바탕을 둔 미적체험’이 포함된다. 두 번째의미는 ‘내 존재로 살아내기 위한 다리를 놓음’, ‘데자뷰의 공간에 머무름’, ‘내 안의 어머니, 그 품에 안김’, ‘순환의 고리로 들어감’, ‘삶의 생기에 붙들림’이 포함된다. 이로써 모성회귀는 전 생애를 다루는 실존적인 의미로탐색되며, 개인의 신체성에 기반이 된 능동적인 활동으로써 삶의 역설적인 내용뿐 아니라 인간보편성과 독특성의 통합을 이룰 수 있는 미술치료로서 응용 가능성을 볼 수 있다.

Complete atrioventricular block during tunneled cuffed hemodialysis catheter insertion in a patient with pre-existing left bundle branch block

최은우,정지윤,서준혁,박세현,조규향,윤경우,박종원,도준영,강석휘 영남대학교 의과대학 2015 Yeungnam University Journal of Medicine Vol.32 No.2

Arrhythmias are complications of tunneled cuffed hemodialysis catheter insertion. Most complications associated with arrhythmias occur during guide-wire access, where the guide wire can cause traumatic damage to the conduction system of the heart. Conducting system injury in tunneled cuffed hemodialysis catheter insertion often involves the right bundle, causing right bundle branch block (RBBB). Transient RBBB with sinus rhythm is not usually accompanied by abnormal vital signs. However if patients already have left bundle branch block (LBBB), new onset RBBB can cause complete atrioventricular block (AVB), which can lead to fatal complications requiring invasive treatment. We report on a patient with LBBB who developed complete AVB during hemodialysis catheter insertion.

미술창작에서 야기된 퇴행의 자기치유적 특성

최은우,최선남 한국상담학회 2014 상담학연구 Vol.15 No.5

In this study, 82 published journals and theses/dissertation on self therapeutic experiences during artwork creating activities were investigated through a meta analysis to gain insights into the therapeutic characteristics of regression caused by creating artwork and the applicability of artwork activities to psychotherapy. The therapeutic characteristics of regression were analyzed in two aspects. First, the temporal, geopolitical, and formative characteristics of regression in the image were analyzed. Second, the analysis regarding how the regression reaches healing was conducted through the grounded theories based on the statement of experiences of the regression during the artwork activities. As a result, first, it was found that the regression occurring in the art transcended the time-space temporally and geometrically by the various formative regression such as retrospection, freedom from all thoughts and ideas, imagination, etc. or reached the areas of private unconsciousness and collective unconsciousness such as childhood, being in the uterus, death, etc. Second, as a result of categorization of experience statements through the open-coding, 180 concepts, 49 sub-categories and 16 categories were appeared. And the relation among the categories is shown through the paradigm of grounded theories. The regression would be in a maternal object relation between relation and communication as archetypes to escape from the difficulties of the reality, and is found to be changed into a positive psychological state and an advanced ego through the processes of psychological restructuring, reexperiencing and integration. With this, this study suggests possibility and application method in psychotherapy by the regression occurring in the artwork. 본 연구는 미술창작 활동에서 자기치유의 체험을 했던 82편의 논문을 대상으로, 메타분석을 통해 미술 작업과정에서 유발되는 퇴행의 치유적인 특성을 연구하여, 미술작업이 가지는 정신치료로서 활용가능성을 알아보았다. 이를 위하여 본 연구에서는 두 가지 과정으로 퇴행의 치유적 특성을 밝혔다. 첫째는 심상에서 나타나는 퇴행의 시간적․지정학적 특성과 형태적 특성을 알아보았고, 둘째는 미술작업과정에서 일어나는 퇴행의 체험적 진술을 근거하여 이러한 퇴행이 어떤 과정을 거쳐 치유에 이르게 되는지를 근거이론으로 분석하였다. 그 첫째 결과, 미술에서 일어나는 퇴행은 회상, 무념무상, 상상 등 다양한 형태적 퇴행에 의해 시간적․지정학적으로 시공간에서 초월되거나 어린 시절, 태내, 죽음 등 개인무의식과 집단무의식의 영역으로 초월됨을 알 수 있었다. 둘째, 개방코딩을 거쳐 체험적 진술 자료를 범주화한 결과, 180개의 개념과 49개의 하위범주, 16개의 범주가 도출되었다. 도출된 범주들 간의 관련성을 근거이론의 패러다임으로 밝혔다. 그 내용을 보면, 미술창작에서 일어나는 퇴행은 현실의 어려움으로부터 벗어나기 위해 원형적 차원에서 관계와 소통의 모성적 대상관계에 놓이게 되며, 심리적 재구성, 재 경험, 통합의 과정을 거쳐 긍정적인 심리상태와 진보된 자아로 변화시킬 수 있음을 알게 되었다. 이로써 미술작업에서 일어나는 퇴행에 대한 정신치료의 활용방법과 가능성을 제시하였다.

The instruments were a career planning maturity scale and the bridge drawing assessment. 13 indexes were rearranged based on the study findings by Teneycke, Hoshino, Sharpe(2009), those by Hays and Lyons(1981), and those by Huh and Ju(2010). Data were analyzed using a frequency, percentage, t-test, and cross-tabulation analysis. The findings are as follows. First, significant differences were found in the direction, bridge kinds, human figures, existence of danger depending on the level of career planning maturity. Second, the subcategory of planning showed significant differences in the direction, the spot where both ends of the bridge meet, objects under the bridges, existence of danger, and human figures. Attitude towards the job showed significant differences in the direction, the location of the participant, objects under the bridge, existence of danger, and human figures. Self-understanding showed significant differences in the shape of the drawings. Dependence showed significant differences in the direction. Exploration and reasonable decision-making showed significant differences in the direction, the spot where both ends of the bridge meets, objects under the bridge, and existence of danger. In this study, an applicability some of the bridge drawing assessment as a tool for preestimating adolescent's career planning maturity has been confirmed. 본 연구는 고등학생의 진로성숙도와 다리그림검사의 반응특성이 어떤 관계가 있는지 살펴보고, 다리그림검사가 청소년의 진로성숙을 파악하는데 활용가능성이 있는지를 알아보는데 목적이 있다. 연구대상은 일반계고등학생과 특성화고등학생 1학년 397명이며, 측정도구는 진로성숙도척도와 다리그림검사를 사용하였다. 다리그림검사의 구성 지표는 Teneycke, Hoshino, Sharpe(2009)연구와 Hays와 Lyons(1981)의 연구, 그리고 허소임, 주리애(2010)의 연구를 참고하여 13개의 지표를 재구성하였다. 자료 분석은 빈도, 백분율, t-test, 그리고 교차분석을 하였다. 그 결과는 다음과 같다. 첫째, 진로성숙도의 수준에 따라 진행방향, 다리종류, 사람의 모습, 위험여부는 유의미한 차이가 있었다. 둘째, 하위영역에서 계획성은 수준에 따라 진행방향, 다리양끝의 장소, 다리 밑의 사물, 위험여부, 사람의 모습과 유의미한 차이가 있었고, 일에 대한 태도는 진행방향, 피검자의 위치, 다리 밑의 사물, 위험여부, 사람의 모습과 유의미한 차이가 있었다. 자기이해는 그림의 형태, 독립성은 진행방향에만 각각 유의미한 차이가 있었다. 탐색과 합리적 의사결정은 진행방향, 다리양끝의 장소, 다리종류, 다리 밑의 사물, 위험여부에 유의미한 차이가 있었다. 본 연구는 다리그림검사의 일부지표를 통해 청소년의 진로성숙을 파악하는데 활용할 수 있음을 확인하였다.

A New Relativistic Hydrodynamic Code for Astrophysics

류동수,최은우,Indranil Chattopadhyay 한국물리학회 2006 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.49 No.4

In relativistic hydrodynamics the relativistic temperature raises the issue of the equation of state (EoS). We present a code for relativistic hydrodynamics with an EoS that is simple but approximates very closely the EoS of a single-component perfect gas in the relativistic temperature regime. Tests with the code are presented to highlight dierences induced by dierent EoS's.inal_ur

Correlations between Optical Coherence Tomography Angiography Findings and Multifocal Electroretinogram Parameters in Retinitis Pigmentosa Patients

한정우,우상언,최은우,온영훈 한국망막학회 2020 Journal of Retina Vol.5 No.2

Purpose: We investigated the correlations between macular function recorded with a multifocal electroretinogram (mfERG) and macular structure evaluated by optical coherence tomography angiography (OCT-A) in patients with retinitis pigmentosa (RP). Methods: In total, 30 eyes of 15 RP patients and 40 eyes of 20 healthy subjects were enrolled in this study. OCT-A and mfERG were performed for all patients. The area and circularity of the foveal avascular zone (FAZ) were measured, and the vessel density (VD) and perfusion density (PD) of the superficial capillary plexus and deep capillary plexus (SCP and DCP, respectively) were estimated. The average amplitude and implicit time of N1, P1, and N2 in rings 1 and 2 were obtained from the mfERG findings. Correlation between the OCT-A results and mfERG parameters were analyzed in RP patients and normal subjects. Results: The mean FAZ area in RP patients increased significantly compared with that in normal subjects (p < 0.001). Both the PD and VD in the SCP and DCP were significantly reduced in RP patients compared with normal subjects (p < 0.001 and p < 0.001, respectively). The mean amplitude of N1, P1, and N2 from rings 1 and 2 were significantly reduced in RP patients compared with normal subjects. The superficial FAZ and deep FAZ area were significantly correlated with P1 amplitude (r = -0.682, p = 0.000 and r = -0.612, p = 0.000, respectively). Both the VD and PD of the superficial plexus were correlated with P1 amplitude on mfERG (r = 0.188, p = 0.021; r = 0.215, p = 0.013; r = 0.323, p = 0.002; and r = 0.362, p = 0.001, respectively). Conclusions: The P1 amplitude from mfERG was significantly correlated with FAZ area and the PD and VD of the SCP and DCP in RP patients. Together, these results suggest that OCT-A together with mfERG is a useful modality for evaluating macular structure and function in RP patients.

IR Correlation Spectroscopy using Microgratings to be Compared with Dispersive IR Spectroscopy#

신권수,조충만,최은우,김성규,김인철,박도현,강영일 대한화학회 2015 Bulletin of the Korean Chemical Society Vol.36 No.3

Microgratings that were designed and fabricated to generate IR absorption spectra of SF6 and NH3 on diffraction into a specific detection angle were tested by correlation spectroscopy. The micrograting diffraction provides a reference spectrum for a target molecule, and its cross-correlation with the transmission spectrum of a gas cell is obtained by varying the diffraction angle. As our optical setup can measure the dispersive transmission spectrum and the correlation spectrum under the same conditions, the two kinds of spectra were compared directly in terms of signal-to-noise ratio (SNR). The SNR’s of the correlation spectra were a few times lower than those of the dispersed spectra; therefore, the correlation spectroscopy can hardly be placed above the dispersive spectroscopy with respect to the SNR. The merit of the correlation spectroscopy is that a rather small range of modulation wavelength is needed to identify the target. Therefore, the correlation spectroscopy would be more useful for such target molecules whose spectra consist of broad peaks spread throughout a wide wavelength range.

최정산 위성추적소의 천체관측 환경에 관한 조사 연구: I. SEEING 및 야천광 관측과 위성추적소의 활용 방안

강용희,윤태석,박병곤,이기원,최영준,최은우,Kang, Yong-Hui,Yun, Tae-Seok,Park, Byeong-Gon,Lee, Gi-Won,Choi, Yeong-Jun,Choi, Eun-Woo 한국천문학회 1996 天文學論叢 Vol.11 No.1

We have investigated the astronomical observational environments at the Choejung-san GEODSS site which is located at the south of Taegu, Korea. As a part of the investigation, seeing and night sky brightness were measured outside nearby the GEODSS site using the Celestron 8-inch portable reflector with $192{\times}165$ pixels Lynxx CCD camera during the period of December 1994 to April 1996. The average seeing values of 4.8 arcsecond in B filter and 5.1 arcsecond in V filter were determined using the IRAF software. These values might be overestimated and would be reduced by at least 1 arc second in both filters if they were measured by more stable telescope system with solid mount and under a dome. We also compare the average seeing value at the GEODSS site with those at three other observatories, the Bohyunsan Optical Astronomy Observatory, the Sobaeksan Optical Astronomy Observatory, and the Seoul National University Observatory, for justification of the above guess. Unfortunately the night sky brightness measurement was not successful mainly due to the short exposure time. The utilizing plan of the GEOSS site is discussed based on the average seeing value, naked-eye sky brightness measurement, analysis of the existing thirty-year weather data and twenty-year urban planning of the metropolitan Taegu city for the year of 2016.
