본 연구는 부부간의 애착손상을 경험한 중년기 성인을 대상으로 외상후성장에 대한 구조모형을 구축하고 검증하기 위하여 수행되었다. 연구대상은 애착손상을 경험한 중년기 기혼 성인 366명으로, 현재 부부관계를 유지하고 있는 자를 대상으로 하였다. 선행연구를 통하여 긍정정서, 부부의사소통, 부부애착, 회복탄력성을 내생변인으로, 외상후성장을 외생변인으로 가설적 모형을 설정하였고, 모형의 적합도를 규명하고 경로를 분석하기 위하여 SPSS 21.0과 Amos 18.0 program을 사용하였다. 연구 결과는 다음과 같다. 첫째, 구조모형의 적합도는 χ2=794.48, df=222, IFI .92, TLI .91, CFI .92, RMSEA=.08 이상으로 적합하였다. 둘째, 긍정정서, 부부의사소통, 부부애착, 회복탄력성이 외상후성장에 미치는 직접효과와 간접효과는 유의하였으며, 이 변인들의 외상후성장에 대한 설명력은 57%로 나타났다. 셋째, 연구변인간의 매개효과를 검증한 결과 연구모형의 내생변인인 부부의사소통, 부부애착, 회복탄력성의 매개효과가 모두 유의하였다. 본 연구 결과는 애착손상을 경험한 중년기 성인의 외상후성장에 대한 교육 및 상담 개입 프로그램의 근거로 활용될 수 있을 것이다. Objectives: The purpose of this study is to construct a structural model of the posttraumatic growth of middle-age adults who have experienced couple attachment injury. Methods: Participants were 366 married, middle-age adults, who experienced attachment-injury. Results: First, as a result of the analysis, the research model is judged to be valid. Second, the direct effects of each variable are found to be significant. Third, the variables positive emotion, couple-communication, couple attachment, and resilience explain 57% of the posttraumatic growth in participants. Fourth, the variables simple indirect effect, multiple indirect effects of couple communication, couple attachment, and resilience are found to have a significant effect on positive emotion relating to posttraumatic growth. Conclusions: This study is meaningful in that it provides the basis for counseling intervention of posttraumatic growth in adults with attachment injury. Finally, the limitations of this study and suggestions for future research are discussed.

국내 도시철도차량의 유지보수는 대부분 예방정비에 기초하고 있다. 기존 유지보수 방법의 한계를 극복하기 위해, 상태기반 유지보수기법을 철도차량에 적용하려는 움직임이 최근 활발히 진행되고 있다. 본 연구는 도시철도차량 제동장치의 핵심 고장부품인 솔레노이드 밸브에 대하여 전류기반 고장진단기법 개발을 시도하였다. 주요 고장부품으로 선정된 솔레노이드 밸브에 대하여, 등가회로모델 및 온도 보상된 전류 감시에 기반한 고장 진단법을 제안하였다. 제안한 고장 진단법의 유효성을 검증하기 위해 실제 도시철도차량에 사용되는 솔레노이드 밸브(상용제동 전자밸브)를 이용하여 사례연구를 진행했다. 본 연구는 철도차량 제동장치의 솔레노이드 밸브 고장진단이 추가 센서의 장착 없이 가능함을 보여주었고, 철도차량의 안전성 및 신뢰성 향상에 도움을 줄 것으로 기대한다. In Korea, urban railway cars are typically maintained using the strategy of predictive maintenance. In an effort to overcome the limitations of the existing strategy, there is increased interest in adopting the condition-based maintenance strategy. In this study, a novel method is proposed to detect faults in the solenoid valves of the braking system in urban railway vehicles. We determined the key component (i.e., solenoid valve) that leads to braking system faults through the analysis of failure modes, effects, and criticality. Then, an equivalent circuit model was developed with the compensation of the temperature effect on solenoid coils. Finally, we presented how to detect faults with the equivalent circuit model and current signal measurements. To demonstrate the performance of the proposed method, we conducted a case study using real solenoid valves taken from urban railway vehicles. In summary, it was shown that the proposed method can be effective to detect faults in solenoid valves. We anticipate the outcome from this study can help secure the safety and reliability of urban railway vehicles.

서유리,신우범,배형원,윤진숙 대한안과학회 2019 Korean Journal of Ophthalmology Vol.33 No.5
Purpose: We sought to investigate the effects of Graves’ orbitopathy (GO) and orbital decompression on laminacribrosa depth (LCD) using spectral-domain optical coherence tomography. Methods: Forty eyes that underwent orbital decompression to relieve compressive optic neuropathy or correctdisfiguring exophthalmos in the context of GO were included. Subjects were imaged with spectral-domain opticalcoherence tomography before surgery and at 1 and 3 months after surgery, at which the examiner measuredthe LCD (distance from the anterior surface of the lamina cribrosa to the Bruch membrane opening line)and peripapillary retinal nerve fiber layer thickness. Subjects were divided into two groups—a muscle-dominantgroup composed of patients who had extraocular muscle enlargement on preoperative orbital computedtomography scan and a fat-dominant group composed of patients who did not show extraocular muscle enlargementon preoperative orbital computed tomography scan—and subgroup analysis was performed. Preoperativeand postoperative intraocular pressure, exophthalmos, LCD, and retinal nerve fiber layer thicknesswere evaluated. Results: At baseline, LCD was remarkably shallower in the muscle-dominant group than in the fat-dominantgroup (95% confidence interval, p = 0.007). In the muscle-dominant group, LCD showed no definite change aftersurgery. However, the fat-dominant group showed temporary posterior displacement of the lamina cribrosaat 1-month postoperation that was reversed to baseline at 3 months postoperation (95% confidence interval, p< 0.01). Conclusions: The lamina cribrosa was anteriorly displaced preoperatively, and its position was nearly unchangedafter the surgery, especially in association with extraocular muscle enlargement. An enlarged extraocularmuscle could reduce the pressure-relieving effect of orbital decompression around the scleral canal inpatients with GO.

A new harbor as been constructing in Gadukdo. However, a lot of fugitive dust gas been often generated from construction site reclaiming sea sand, especially when the Northwester is blown strongly. It has resulted insome appeals of residents in Gadukdo. In this study, we estimated the amount of fugitive dust caused by new harbor construction using Fugitive dust formula. Also, the concentration of PM10 for recipient is predicted by AERMOD. The amount of fugitive dust is 26.56 ${\mu}g/sec{\cdot}m^2$ and 11.84 ${\mu}g/sec{\cdot}m^2$ respectively by the Fugitive dust formula. PM10 outlet concentration and the amount of fugitive dust increase according to wind velocity and directions. AERMOD is performed on the basis of weather data and the amount of fugitive dust generated with wind velocity. As a result of AERMOD, the PM10 concentration of Sunchang and Oinul are predicted over 100 ${\mu}g/m^3$. The PM10 concentration of Sunchang and Oinul are predicted over 130 ${\mu}g/m^3$ when wind velocity of northwester in winter is over 11 m/s (Air Quality for Particulate Matter (100 ${\mu}g/m^3$ for 24 hours)). Also, the measured error between AERMOD and actual measurement is lower than 5%.
