본 연구에서는 항공기 기반 FMCW-SAR(Frequency Modulated Continuous Wave-Synthetic Aperture Radar) 시스템의 연속이동효과를 분석하고, 이를 보정하기 위한 신호처리 연구 결과를 설명하며, 보정된 레이다 신호를 back-projection 알고리즘 기반으로 복원시킨 SAR 영상 품질 개선 결과를 포함한다. FMCW 신호기반 SAR 시스템의 연속이동효과를 FMCW신호 모델을 이용하여 항공기 이동 속도와 샘플링 주기 등의 영향을 분석하고, 이를 개선시키기 위해 시간-도플러(t, ku) 영역에서의 레이다 신호처리 기법을 적용하였다. 이때, FMCW-SAR 영상 복원을 위해 back-projection 알고리즘과 수정된 정합필터를 활용하였으며, 항공기 기반으로 수집된 실제 X-밴드 대역 데이터에 적용하여 연속이동효과 개선 결과를 확인/검증하였다. Results of an analysis of the continuous motion effect for FMCW-SAR system and a signal processing to correct it are presented in this paper. SAR images reconstructed by back-projection algorithm are included as well. To analyze how platform velocity and sampling frequency affect the continuous motion effect, FMCW signal model was used, and the signal processing in time-doppler(t, ku) domain was adopted. Then, back-projection algorithm and modified matched-filter was used to reconstruct SAR images, and it was validated using measured data by airborne FMCW-SAR system in X-band frequency.

본 연구는 COVID-19 팬데믹 이후 필요성이 한층 증가된 비대면 화상상담을 시행하고 있는 상담사들의 경험을 통해 비대면 상담의 경험과 비대면 화상상담의 특징을 탐색하기 위해 수행되었다. 이를 위해 비대면 화상상담 시스템이 안정적으로 구축된 D 대학원 상담센터에 주목하고, 최근 6개월 이내에 10회기 이상 진행한 사례를 2사례 이상 가진 상담자 13명을 참여자로 선정하였다. 합의적 질적 연구(CQR)방법에 따라 자료를 수집, 분석하여 3개의 영역, 8개 범주가 결과로 도출되었다. <비대면 화상상담에 대한 개인적 경험> 영역에서는 ‘가상공간에 대한 불확실성에 대한 염려와 긴장’, ‘우려를 불식시킨 긍정적 경험’, ‘전문가로서의 성장 기회’, <비대면 화상상담의 평가> 영역에서는 ‘시공간 제약의 초월’, ‘물리적 거리감이 주는 한계’, ‘대면 상담과의 차이’, <비대면 화상상담 운영을 위한 제언> 영역에서는 ‘필요조건’, ‘지원체계 확보’로 구조화하였다. 본 연구는 새로운 상담 방식인 화상상담의 긍정성과 한계를 확인하고, 상담사로서의 성장 과정을 탐색하였다는 것에 의의가 있다. 마지막으로 본 연구의 제한점과 추후 연구를 위한 논의를 제시하였다. This study explored counselors’ experiences in teletherapy, which has increased since the COVID-19 pandemic. This study was conducted with counselors at the D Graduate School Counseling Center, which had a stable teletherapy system. Among the counselors, 13 therapists who had conducted at least 2 cases of 10 or more sessions within the past 6 months were selected. The consensual qualitative research (CQR) method was utilized, and 3 domains and 8 categories were derived as a result. The domains are as follows; <Personal experience with teletherapy>, <Evaluation of teletherapy>, <Suggestions for operating teletherapy>. The implication is that the study confirmed the positives and limitations of teletherapy as a new counseling method. Lastly, the study's limitations and suggestions for future research were discussed.

본 연구는 사회적 재난과 같은 환경의 위협과 스트레스 상황에서 위기를 겪는 부부를 돕고자 기혼자의 자기분화, 결혼 만족, 불안정 성인애착 간의 관계를 알고, 그들이 지각하는 자기분화 수준과 결혼 만족의 관계에서 불안정 성인애착의 매개효과를 검증하는 것을 목적으로 하였다. 설문지는 서울, 경기지역에 거주하고 있는 기혼 내담자 200명을 대상으로 하여, 자기분화 수준, 결혼 만족, 불안정 성인애착을 측정하였다. 설문지에 잘못 기재하거나, 무성의하게 응답한 28부를 제외한 172부의 자료만 최종 분석에 사용하였다. 세 변인들 간의 관련성을 살펴보기 위해 상관분석을 실시하였고, 매개효과를 알아보기 위하여 SPSS MACRO PROCESS을 활용하여 회귀 기반 경로분석 (ordinary least squares regression-based path analysis)을 실시하였다. 본 연구를 통하여 밝혀진 결과는 다음과 같다. 변인 간의 상관을 살펴보면 자기분화는 불안정 성인애착과 불안정 성인애착과 결혼 만족도와 부적 상관을 보였다. 자기분화는 결혼 만족에 직접적인 영향을 끼치지는 않지만, 자기분화가 낮을수록 불안정 성인 애착이 높음으로써 결혼만족이 낮아지는 완전 매개효과가 나타남을 알 수 있다. 본 연구를 통해 결혼의 만족에 어려움이 무엇인지를 확인하는 한편, 부부 상담 접근에 적용하기 위한 유용한 자료를 제공하고자 한다. 또한, 본 연구 결과를 토대로 후속 연구에 대한 제언과 시사점을 논의하였다. The purpose of this study is to understand the relationship among differentiation of self, marital satisfaction, and insecure adult attachment in married people. This study is to help couples who suffer crises in environmental threats such as social disasters, and to verify the mediating effect of insecure adult attachment on the relationship between their perceived levels of differentiation of self and marital satisfaction. The questionnaire measured the level of differentiation of self, marital satisfaction, and insecure adult attachment to 200 married clients living in Seoul and Gyeonggi Province. Only 172 copies of data were used for the final analysis, excluding 28 copies that were incorrectly entered in the questionnaire or responded insincerely. Correlation analysis was conducted to examine the relevance between the three variables, and regression-based path analysis was performed using SPSS MACRO PROCESS to find out the mediating effect. The results revealed through this study are as follows. Looking at the correlation between variables, differentiation of self was found to be negatively correlated with insecure adult attachment and marital satisfaction. Differentiation of self does not directly affect marital satisfaction, but it can be seen that the lower the differentiation of self, the higher the insecure adult attachment, resulting in a complete mediating effect in which marital satisfaction decreases. Through this study, it is intended to provide useful data for application to marital counseling access while identifying what difficulties are in marital satisfaction. In addition, suggestions and implications for subsequent studies were discussed based on the results of this study.

Objective: Although hypothermia is known to have a neuroprotective effect on brain injuries as well as to decrease intracranial pressure, the neuroprotective effect in spinal cord injury(SCI) has not been proven. The author performed this experiment to evaluate the effect of systemic hypothermia on neurological improvement and histopathological change in traumatic SCI of rat. Methods: In experiment Ⅰ, spinal cord contusions were implemented in 35 rats that had been divided into 3 groups. Rats in Group 1(N=12) were kept with normothermia, while Group 2(N=10) received hypothermic treatment for 5 hours and Group 3(N= 13) for 20 hours. The experiment was held over two weeks and clinical assessment of locomotor function was made by utilizing the Basso-Beattie-Bresnahan(BBB) locomotor rating scale. Histopathological studies were performed at 2 weeks by hematoxylin & eosin, luxol fast blue and TUNEL staining. To analyze the effect of hypothermia for 20 hours on apoptosis, the author evaluated histopathological findings 3 days after SCI in experiment Ⅱ. Eighteen rats with SCI in experiment Ⅱ, were kept with normothermia in Group 4(N=9) and treated by hypothermia for 20 hours in Group 5(N=9). The spinal cords were excised and stained 3 days after SCI. Results: Fourteen days after SCI, BBB scales in Group 1(N=9), Group 2(N=9), and Group 3(N=13) were 7.9±2.8, 10.0±3.2, 13.9±2.5, respectively, which were statistically significant(ANOVA, p=0.001). The area of spinal cord tissue defect in Group 1, Group 2 and Group 3 after 2 weeks were decreased gradually, which were 4.1±2.0 mm², 2.9±1.9 mm², 2.0±1.9 mm², respectively, but statistically insignificant(ANOVA, p=0.064). In experiment Ⅱ, the sizes of necrotic areas in Group 4 and Group 5 were 5.9±2.2 mm², 3.8±2.3 mm², respectively, which were not statistically significant(p=0.074). However, the ratio of TUNEL staining positive cells decreased significantly in Group 5(p=0.015). The ratios were 0.30±0.10 in group 4 and 0.16±0.12 in group 5. Conclusion: In this study, systemic hypothermia for 20 hours improved neurological recovery and decreased the ratio of apoptosis in traumatic SCI of rat. In addition, hypothermic treatment showed a tendency of reducing necrosis and tissue defect after SCI.
