본 연구는 신생아 및 소아 중환자실 간호사의 도덕적 민감성과 도덕적 고뇌가 돌봄 행위에 미치는 영향을 파악하기 위한 서술적 조사연구이다. 자료수집은 2020년 11월 11일부터 12월 2일까지 2개 지역 5개 상급종합병원을 대상으로 자가보고식 설문조사를 진행하였다. 연구대상자는 신생아 및 소아 중환자실에 근무하는 실무경력 1년 이상의 간호사 128명이었으며, 최종 121명을 분석에 포함하였다. 연구결과, 도덕적 민감성 4.91±0.45점, 도덕적 고뇌 4.39±2.60점, 돌봄 행위 5.11±0.81점으로 확인되었다. 연령에 따라 도덕적 민감성(p=.002), 도덕적 고뇌(p=.001), 돌봄 행위(p=.013)는 유의한 차이를 보였으며, 경력, 결혼 여부, 전문적 상담의 필요성 여부, 윤리교육 및 윤리 세미나 참석 경험 등도 유의한 차이가 있었다. 다중회귀분석 결과, 도덕적 민감성(p<.001)과 도덕적 고뇌(p=.027)는 돌봄 행위에 대하여 유의한 영향을 끼치는 것으로 확인되었으며, 각 모형의 설명력은 22.5%, 10.3%이었다. 또한, 도덕적 민감성의 하위 요인인 환자중심간호(p<.001)와 도덕적 고뇌의 하위 요인인 윤리적 문제를 주장하는 데 대한 제약(p=.009)이 돌봄 행위에 대하여 유의미한 예측력을 가진 변인으로 확인되었다. 따라서 신생아 및 소아 중환자실 간호사가 처한 특수한 상황으로 인한 윤리적 딜레마를 이해하고, 돌봄 행위 향상을 위하여 도덕적 민감성을 증진시키고 도덕적 고뇌를 낮출 수 있는 중재 마련이 필요하다.

목적: 각막이식수술 전 정확한 이식 적합성 평가를 위하여 기증각막이 담긴 보존액 병을 고정시킬 수 있는 장치를 개발하였으며, 국내기증각막을 대상으로 세극등현미경검사를 시행하여 고안된 장치의 효용성을 평가해보고자 한다. 대상과 방법: 2023년 2월부터 2023년 3월까지 여의도성모병원에서 기증받는 국내 기증각막 2안을 대상으로 하였다. 기증각막이 담긴보존액 병을 고안된 장치의 홀더에 장착하여 세극등현미경에 설치하면, 세극등현미경의 빔은 장치의 거울에 의해 반사되어 보존액내의 각막에 입사하고, 이를 세극등현미경에서 관찰할 수 있다. 각막내피가 보존액 병의 위를 향한 상태와 바닥을 향한 상태에서 세극등현미경검사를 시행하고 전안부 사진을 촬영하였다. 또한, 고안된 장치를 이용하여 기증각막에 경면현미경검사와 전안부 빛간섭단층촬영을 시행하였다. 결과: 기증각막이 담겨있는 보존액 병을 장치에 고정한 상태에서 세극등현미경을 이용하여 공막 변연부를 360° 관찰하여 버트닝 상태를 확인하고, 세극등현미경의 좁은 빔으로는 각막 단면을 확인할 수 있었다. 역조명법을 이용하여 각막상피세포를 관찰할 수 있었으며, 경면반사법을 통해 내피세포층이 확인되었다. 그러나 경면현미경검사 및 빛간섭단층촬영검사 시 내피세포밀도와 각막두께는 측정되지 않았다. 결론: 저자들이 고안한 기증각막검사용 장치는 국내 기증각막에 대한 세극등현미경검사를 쉽고 안정적으로 시행할 수 있게 하며, 각막내피나 두께에 대한 정성적인 평가가 가능하였다. Purpose: To evaluate the effectiveness of an instrument devised for slit-lamp examination of donor corneas suspended in preservation medium. Methods: The study examined two donor corneas received at Yeouido St. Mary's Hospital in February 2023 and March 2023. The instrument has three main components: a plastic holder to hold the preservation medium bottle, a cube with a mirror for reflecting the slit beam, and a stand to attach the device to the slit-lamp. Using the instrument, the donor corneas were examined via slit-lamp: microscopy with the endothelium facing upward and downward. Specular microscopy and anterior segment optical coherence tomography (OCT) were also performed on the preserved donor corneas. Results: Slit-lamp examination of donor corneas in preservation medium using the instrument showed overall corneal buttoning and optical sections of the donor cornea. Using specular reflection and retroillumination, the endothelial layer was partially visible. However, specular microscopy and anterior segment OCT could not examine the donor cornea in preservation medium using the instrument. Conclusions: The devised instrument facilitates slit-lamp examination of donor corneas in preservation medium, enabling a qualitative assessment of donor corneas before corneal transplantation surgery.

This study aimed to investigate the contamination sources of button mushrooms by assessing the microbial load on the mushrooms and in the agricultural inputs that come into contact with the mushroom. A total of 234 samples including mushrooms, compost, casing soil, and tools from A, B, C, and D farms were tested for sanitary indicators (aerobic bacteria, coliforms, and Escherichia coli) and foodborne pathogens (E. coli O157:H7, Salmonella spp., Staphylococcus aureus, and Listeria monocytogenes). To identify the contamination source, E. coli was isolated and analyzed using MLST (Multi-Locus Sequence Typing). The number of aerobic bacteria remained consistent during composting (>7 log CFU/g); however, the occurrence of coliforms and E. coli was reduced to the detection limit (<1.0 log). Salmonella spp. and L. monocytogenes were detected in the raw material; however, they were inactivated during composing. More than 6.0 log of aerobic bacteria and 3.0 log of coliforms were observed in the casing soil from A, B, and C farms and in the gloves from the C farm. MLST indicated that the STs of E. coli isolated from casing soil layer and from the harvested mushrooms were identical at ST 189. Therefore, cross contamination occurred through the casing soil layer, and this could contribute to E. coli contamination in mushrooms. It is necessary to practice hygiene guidelines, such as sterilization of casing soil, worker hygiene, and facility sanitation, to minimize the potential of microbial contamination in mushrooms.

0.75(Bi1/2Na1/2)TiO3-0.25SrTiO3 (BNT-25ST) ceramics with high densities were successfully prepared at a sintering temperature of 1,000℃ by adding a mixture of 1 mol% CuO and 0.5 mol% Na2CO3 or 0.5 mol% CuO and 0.25 mol% Na2CO3. Double polarization-electric field (P-E) hysteresis curves and sprout-shaped bipolar strain-electric field (S-E) hysteresis curves with small negative strains were observed in the pristine and CuO-added BNT-25ST ceramics whereas the Na2CO3-added sample showed similar P-E and S-E curves to a typical ferroelectric. The pristine BNT-25ST ceramics showed an extremely large strain and a large-signal piezoelectric strain constant (d33*): 0.287 % at 80 kV/cm and 850 pm/V at 20 kV/cm. Similar values, 0.248 % at 80 kV/cm and 655 pm/V at 20 kV/cm, were obtained in the CuO-added sample. However, the pristine and CuO-added samples showed large hysteresis in unipolar S-E curves at an electric field of less than 20 kV/cm. The Na2CO3-added sample showed smaller values of the strain and d33* but displayed a linear change and small hysteresis in the unipolar S-E curve. The co-added sample with CuO and Na2CO3 displayed intermediate P-E and S-E hysteresis curves.

Purpose: The obesity prevention and management program led by public health centers are important in the community. This study aims to identify the current status of obesity prevention and management programs at public health centers and perceptions regarding facilitators and barriers when implementing programs. Methods: This study used a concurrent mixed methods design. A survey was conducted to investigate the current status and infrastructure of the obesity prevention and management program at eighty-three public health centers nationwide. Nine program managers and six local residents with experience in the program were interviewed by using a semi-structured questionnaires. Results: Most of the infrastructure facilities for the program were inadequate, and insufficient budgets and lack of professional staff were identified as barriers. Facilitators included diversification of program delivery methods, operator competence, and visible outcomes and rewards. For the effectiveness of the program, it is vital to have adequate assistants, a sufficient budget, various promotional methods, and connections with various institutions in the community. On this basis, it is acknowledged that the public health center serves as a platform for preventing and managing obesity in the community. Conclusion: It is expected that infrastructure improvements in public health centers and the link with community resources are needed. In addition, there is an urgent need to set standards for obesity prevention and management programs implemented in public health centers to ‘resolve regional disparities’.

Objectives: The burden on caregivers of dementia patients is a crucial factor in the quality of life and disease management for both the patient and the caregiver. However, research on caregiver burden at the time of initial dementia diagnosis is lacking. This study aims to investigate the factors related to caregiver burden in caregivers within three months of dementia diagnosis. Methods: A total of 85 caregivers, whose care recipients were aged 65 or older and had been diagnosed with dementia within the past three months, were surveyed. Caregivers whose care recipients were institutionalized were excluded from the study. The Caregiver Burden Inventory was used to measure caregiver burden. Socio-demographic factors of the patient and caregiver, clinical characteristics of the patient, caregiver's depressive symptoms, attitudes toward dementia, coping skills, and social support were examined. Results: Higher severity of dementia in the patient, female gender of the caregiver, cohabitation of caregiver and patient, and more severe depressive symptoms in the caregiver were significantly associated with higher caregiver burden. Additionally, caregivers using negative coping strategies, having negative attitudes toward dementia, and receiving less social support experienced higher caregiver burden. Multivariate regression analysis results showed that only caregiver's gender and depressive symptoms were significantly related to caregiver burden. Conclusions: Caregiver depressive symptoms at the time of initial dementia diagnosis were found to increase caregiver burden. It is essential to identify risk factors for caregiver burden from the early stages of diagnosis and implement interventions to reduce caregiver burden.
