Purpose: Despite the health impacts of endocrine-disrupting chemicals (EDCs) beginning in the early stages of life, there is little research on the perception of EDCs among Korean mothers, who are primarily responsible for protecting children. This study aimed to explore how mothers with young children perceived EDCs for their concerns, the issues they faced, and the way they dealt with them.Methods: An exploratory qualitative design was utilized. Twelve mothers who were recruited from snowball sampling participated in voluntary interviews. Individual in-depth interviews lasting approximately 47 to 60 minutes were recorded and transcribed verbatim. The data were analyzed using qualitative content analysis as suggested by Graneheim and Lundman.Results: Four categories, 10 subcategories, and 25 condensed meaning units were identified by interpreting mothers’ underlying meanings. The four categories were ‘Knowledgeable yet contrasting ideas regarding EDCs,’ ‘Negative health impact, but more so for children,’ ‘Inaction or trying to minimize exposure,’ and ‘Need for early, reliable resources and social change.’ Mothers were knowledgeable about EDCs and actively needed further education and support. While they tended to focus more on the health impact of EDCs on their children and were optimistic about their health risks, paying less attention to their preventive behaviors.Conclusion: Healthcare professionals must consider mothers’ perceptions of EDCs in future education and interventions regarding EDCs impact on women’s life stages such as puberty, pregnancy, and childrearing. Also preventive strategies that can be applied to their daily lives are needed.

Aims: This study examined the effects of an action-guided intervention on reducing optimistic bias about reproductive health risks related to endocrine disruptors and improving protective behaviors against endocrine disruptors. Methods: A quasi-experimental design with a nonequivalent comparison group was used with a pretest and double posttest. A convenience sample of 139 young adult women was recruited through social network services from May to June 2020. Unmarried women aged 20-29 years with a regular menstrual cycle and no present illness were included. They were sequentially numbered, and those with odd and even numbers were assigned to the experimental (n=69) or control (n=70) group, respectively. An action-guided intervention based on the knowledge-to-action framework of Graham et al. was administered by one nurse interventionist. A 60-minute online education session and a 30-minute booster session were provided to seven small groups, while the comparison group received a leaflet. Data were collected via email at baseline and at 4 and 12 weeks post-intervention. Descriptive statistics, repeated-measures ANOVA, and the McNemar test were conducted. Results: A significant difference was found in protective behaviors between the groups (F=81.21, p<.001), the effects remained consistent over time (F=59.96, p<.001), and there was an interaction effect of group and time (F=41.26, p<.001). However, the proportion of women with optimistic bias about reproductive health risks related to endocrine disruptors was only significantly lower in the experimental group than in the comparison group at 12 weeks post-intervention (χ2=33.55, p=.031). Conclusions: The action-guided intervention was effective in improving protective behaviors against endocrine disruptors by providing information on specific sources of endocrine disruptors and their health consequences, as well as detailed behavioral strategies. Optimistic bias takes more effort to change; thus, accurate knowledge and information should be provided to women to build realistic awareness of the health risks of endocrine disruptors.

범용적으로 고진공 성막 장비에서 사용되는 quartz crystal microbalance (QCM)는 두꺼운 필름이 quartz 위에 성막되는 경우, 크리스탈 고유의 진동에 영향을 주어 사용이 어려워진다. 본 논문에서는 실시간 필름 증착 공정 중에 센서의 손상이 없는 광학적 계측 방식을 통해 필름의 성막 속도를 측정하는 방법을 연구하였다. 기체 이동 경로로 지나가는 페럴린 가스 중 다이머에 의한 레이저의 산란 정도를 측정하여, 페럴린 공정의 분해부 온도가 감소할수록 페럴린 가스 중 다이머의 비율이 증가하는 것을 성공적으로 확인하였다. 또한, 성막된 필름의 특성을 확인한 결과, 분해부 온도가 감소할수록 필름의 두께와 haze가 증가한 것을 확인할 수 있었다. 우리는 연구 결과를 통해 개발한 안정적인 실시간 성막 속도 계측 시스템을 이용함으로써, 진공 공정을 통해 성막하는 페럴린 필름의 정밀한 성막 속도 제어에 활용하고자 한다. The quartz crystal microbalance (QCM), commonly used in high vacuum deposition, becomes difficult to use when a thick film is deposited on the quartz, affecting the crystal's inherent vibration. In this study, a non-destructive optical measurement method was developed to measure the film's deposition rate during the in-situ film deposition process. By measuring the scattered laser intensity caused by the dimer in the parylene gas passing through the gas flow path, it was successfully confirmed that the ratio of the dimer in the parylene gas increases as the pyrolysis temperature decreases. Additionally, it was noted that the film's thickness and haze increase as the pyrolysis temperature decreases by confirming the characteristics of the visible parylene films. Through the research results, we aim to utilize the stable in-situ film deposition rate measurement system to control the precise film deposition rate of parylene films.
