Background: Pregnancy-related low back pain (PLBP) has fewer systematic guidelines than pregnancy-related pelvic girdle pain, previous studies have not evaluated physical therapy for this ailment in Korea. Objects: We aimed to provide a detailed account of clinical decision making by Korean physiotherapists while treating PLBP. Methods: In total, 955 questionnaires were distributed mainly in places of continuing education held by the Korean Physical Therapy Association from April to July 2019. The same questionnaire was posted on a website used by physiotherapists. We collected subject information, a specific Vignette typically represent symptoms of PLBP, and responses to multiple questions about decision making, subjective recognition and interest level in the field of women’s health physiotherapy (WHPT). Results: The overall response rate was 56% (n = 537); of these, responses to 520 questionnaires were analyzed. Most respondents chose various combinations of physical therapy methods. There were significant differences in subjective recognition levels of WHPT according to gender (p < 0.05), age (p < 0.01), education level (p < 0.01), and clinical experience (p < 0.05). There were significant differences in interest according to gender (p < 0.01) and education level (p < 0.01). With respect to the types of treatment, significant differences were noted in selective rates for “manual therapy”, “pain control”, and “supportive devices” based on gender. Manual therapy tended to be chosen more with increasing age and clinical experience. With increased education level, there were fewer choices for the use of pain control. Conclusion: This is the first data on how Korean physiotherapists manage PLBP patients using the vignette method. We were able to recognize the Korean physical therapist's decision on PLBP patients, and observed statistically significant correlations. This may aid in developing future research and education plans in the WHPT field.

본 연구에서는 전기분해 방법을 이용한 질산성질소(NO3 --N) 분해가 TiO2 nanotube plate 및 구리, 니켈, 스테인리스 스틸, 알루미늄, 주석, 티타늄을 환원전극으로 사용하였을 때 가능한지를 평가하였다. 전극의 전기화학적 특성 평가는 임피던스 측정을 하여 비교하였고, TiO2 nanotube plate의 표면 분석은 주사전자현미경을 통해 SEM 및 BET 분석법을 이용한 비표면적 분석을 통해 비교하였다. 질산성질소 전해실험의 경우 90분의 실험을 진행하였으며, 실험 결과 전극 표면의 부식이 수반되지 않은 TiO2 nanotube plate가 기타 금속 전극에 비해 질산성질소 환원 반응속도가 가장 뛰어난 것으로 확인되었다.
