폴리다이메틸실록산 코팅을 통한 다결정성 UiO-66 분리막의 비선택적 결정립계 결함 캡핑

김익지,권혁택 한국청정기술학회 2023 청정기술 Vol.29 No.1

In general, the presence of non-selective intercrystalline (grain boundary) defects in polycrystalline metal-organic framework (MOF) or zeolite membranes, which are known to be ca. 1 nm in size, causes lower membrane performance (selectivity) than the intrinsically expected. In this study we show that applying a thin polymeric coating of polydimethylsiloxane (PDMS) on a polycrystalline MOF membrane is effective to cap the non-selective intercrystalline defects and therefore improve membrane performance. To demonstrate the concept, first, polycrystalline UiO-66, one of Zr-based MOFs, membranes were prepared by an in-situ solvothermal growth. By controlling membrane growth condition with respect to growth temperature, we were able to obtain polycrystalline UiO-66 membranes at 150 o C with intercrystalline defects of which the quantity is not significant, so it can be plugged by the suggested PDMS deposition. Second, their performances were compared before and after the PDMS deposition. As expected, the PDMS deposition ended up with a noticeable increase in CO2/N2 ideal selectivity from 6 to 14, indicating successful intercrystalline defect plugging. However, the enhancement in CO2/N2 selectivity was accompanied by a significant reduction in CO2 permeance from 5700 to 33 GPU because the PDMS deposition not only plugs defects but also forms a continuous coating on membrane surface, adding an additional transport resistance. 다공성 결정물질(예: 금속유기골격체(Metal-Organic Framework, MOF), 제올라이트(zeolite))로 만들어진 다결정성 분리막의 선택도는 일반적으로 크기가 1 nm 혹은 그 이상으로 알려진 비선택적 결정 간 결함, 즉 결정립계의 존재 때문에 저하된다. 본 논문에서는 다결정성 MOF 분리막 위에 폴리다이메틸실록산(polydimethylsiloxane, PDMS)의 코팅이 결정립계를 캡핑하여 분리막의 선택도를 향상시키는데 효과적임을 증명하였다. 제안된 개념을 증명하기 위해서 in-situ 용매열 합성법을 통해 제조된 지르코늄 기반의 MOF의 일종인 UiO-66 분리막 위에 PDMS를 코팅한 후, 코팅 전후의 성능변화를 관찰하였다. PDMS 코팅 후 UiO-66 분리막의 CO2/N2 단일 기체 분리 선택도는 6에서 14로 증가하였고, 동시에 CO2 투과도는 5700 GPU에서 33 GPU로 감소하였다. 선택도의 증가는 PDMS 코팅이 결정립계 결함을 효과적으로 메웠음을 의미하며, 동반된 투과도의 감소는 PDMS 코팅이 결함을 메우는 동시에 분리막 위에 연속적인 층을 형성하여 추가된 투과 저항에서 비롯되었다고 판단된다.

Objectives: With the rapidly increasing incidence of cancer worldwide, it has become important for health care professionals to both provide care for cancer patients and to address the challenges faced by family caregivers of cancer patients. This study aims to identify the factors affecting depression among cancer patients’ family caregivers. The results of this study suggest the need to propose programs for family caregivers as well as cancer patients. Methods: Participants were 219 caregivers who were informed of the study purpose and agreed to participate. Data were analyzed using t-tests, one-way ANOVA, Scheffe’s test, Pearson correlation coefficients, and multiple stepwise regression with the SPSS/WIN 25.0 program. Results: The mean score for depression among cancer patients’ family caregivers was 1.57±.40 (range: 0–3). Depression was significantly different based on age, relationship with the patient, education, occupation, cancer recurrence, care days per week, financial burden, site of cancer, and health status. Analysis using multiple regression showed that model 1 showed 16% of the factors predicting depression among cancer patients’ family caregivers (F=6.16, p<.001) including occupation, recurrence, and health status of the caregiver. Model 3, which included additional burnout, showed 37% of the factors predicting depression (F=12.36, p<.001). Conclusions: These results suggest that it is necessary to develop programs for prevention and management of depression among cancer patients’ family caregivers.

본 연구의 목적은 간호대학생의 의사소통능력, 눈치, 임상실습교육환경 및 임상수행능력의 관계를 파악하기 위한 시도된 서술적 조사연구이다. 본 연구의 자료수집은 2019년 3월 15일부터 28일까지 B시와 G시 소재 4개 대학의 간호학과에 재학 중인 3, 4학년 학생 214명을 대상으로 구조화된 설문지를 이용하여 수집하였다. 자료분석은 SPSS 25.0 프로그램으로 t-test, ANOVA, Scheffé 검정, Pearson 상관 계수 및 다중회귀 분석을 이용하여 분석하였다. 연구결과 의사소통능력, 눈치, 임상실습교육환경은 임상실습수행능력과 유의한 상관관계가 있는 것으로 나타났다. 간호대학생의 임상수행능력에 영향을 미치는 요인들은 의사소통능력, 눈치, 임상실습교육환경이었으며, 이들 변수의 설명력은 32%이었다. 따라서 간호대학생의 임상실습수행능력의 향상을 위해서는 상황을 이해하는 능력인 눈치를 고려한 의사소통능력을 개발할 수 있는 프로그램의 개발이 필요하며, 교육기관과 실습기관의 적극적인 협력을 통해 긍정적인 임상실습교육환경에 조성이 요구된다. The purpose of this study was to identify the relationships between the communication competency, nunchi, clinical learning environment and clinical practice competency in nursing college students. The data were collected using structured questionnaires from 214 nursing students enrolled in 4 colleges in B and G city between March 15 to 28, 2019. The data were analyzed using t-test, ANOVA, Scheffé test, Pearson correlation coefficient, and multiple regression using SPSS 25.0 program. As a result, the communication competency, nunchi, clinical learning environment was found to have a significant correlation with clinical practice competency in nursing college students. Factors influencing clinical practice competency among participants include communication competency, nunchi and clinical learning environment. These variables explained 32% of the total variance in clinical practice competency. Therefore, in order to form desirable clinical practice competency of nursing college students, it is necessary to develop program for communication skill considering nunchi, the ability to understand the situation and to establish a positive clinical learning environment through cooperation between the school and the training institute.
