        Purpose: In this study, we aim to understand and explore the anxiety caused by illegal filming and to develop strategies to relieve this anxiety among young Korean women. Methods: Seven young Korean women were recruited through public announcements using the photovoice method, a type of participatory action research. Photographing, classification of the collected photos, and focus group interviews were conducted. Participants engaged in various structured activities, including orientation sessions to introduce the research objectives and methods, photo taking to document their anxieties, photo submission and categorization, and focus group discussions to share their experiences and reflections. Data analysis was conducted using a six-step thematic analysis method to ensure the validity and reliability of the findings. Results: Five themes and 11 subthemes were derived based on the participants’ anxiety about illegal filming. The first theme, “Tension that persists in everyday life” included cautious behavior on uphill paths, highlighting how anxiety shapes everyday decisions and physical behaviors in public spaces. The second theme, “Searching for illegal cameras due to anxiety,” encompassed specific actions that participants regularly undertook, such as using camera detection applications, carrying specialized preventive items, and routinely checking for reflections using fingers and mirrors to ensure privacy. The third theme, “Efforts to avoid harm,” detailed participants’ intentional selection of safe environments, such as utilizing secure restroom facilities, choosing locations equipped with safety mirrors, and consciously observing illegal filming prevention banners. The fourth theme, “Exposed to illegal filming crimes,” involved direct experiences with illegal filming crimes, including discovering holes in public restroom walls, encountering cameras concealed in shoes, and experiences with silent or disguised cameras. Finally, the fifth theme, “Mental distress due to accidental damage” resulting from unintended victimization, was poignantly captured in participants’ descriptions of having negative emotional and psychological experiences, emphasizing the long-lasting impacts of such invasions of privacy. Implications: The findings provide critical foundational insights into the specific anxieties that young Korean women experience about illegal filming. This study provides valuable information that can inform effective prevention and management strategies. Participants’ proactive behaviors, including adopting detection tools, carrying prevention-focused items, and using safety-enhancing public facilities, underscore significant efforts to manage personal anxieties. These individual-level strategies highlight the urgent need for broader, systematic, and institutional support structures to effectively combat and mitigate anxieties related to illegal filming. Suggestions: Based on these findings, several recommendations are proposed. First, future research should expand the participant demographics by including women across various age groups and occupational backgrounds. Second, given the subjective interpretations inherent in the photovoice methodology, repeated studies are essential for uncovering additional meanings, themes, and deeper contextual understanding. Finally, future research employing the photovoice method should integrate diverse interpretive activities, allowing participants to analyze and articulate their photographic narratives more profoundly. Such comprehensive and multifaceted research approaches will significantly enhance our understanding of women’s anxieties regarding illegal filming and contribute to developing more robust, effective, and responsive policy interventions and societal support mechanisms.

        Bunhwangsa Stone Brick Pagoda, constructed in 634, is Korea's oldest stone pagoda. As a prototype of the Silla Stone Pagoda, the pagoda was constructed using flagstones. Since it was constructed with flagstones, it has been known to be a pagoda that replicates the brick pagoda until now. The latest research suggests that it copies the India Stupa or the Stacked Stone Pagoda more than the Brick Pagoda. However, the Bunhwangsa stone brick pagoda has a significant difference in terms of construction technique and shape compared to Brick Pagodas, India Stupas, and Stacked Stone Pagodas. Therefore, it is worth paying attention to the stone building technique used in Silla. Through this study, I would like to clarify that the Bunhwangsa stone brick pagoda is a stone pagoda that creatively reflects the existing Silla stone building techniques such as stone fortresses and stone chamber tombs.

        Purpose: This study aims to explore the students’ experiences of taking class in nursing philosophy at the graduate school of nursing. Methods: Data were collected through individual in-depth interviews with 18 participants who took nursing philosophy class. Core question was 'What is your experience of taking nursing philosophy class?' Verbatim transcripts were analyzed using content analysis. Results: Qualitative data analysis revealed nine theme clusters in four categories; 'The distance from philosophy that is too far to be friendly’, ‘Finding the academic roots of nursing',’The way to find answers through creative insights' and ‘Presenting a vision of nursing through reflection and maturity'. Conclusion: Nursing graduate students initially encountered challenging thoughts and a sense of detachment from reality when they embarked on their nursing philosophy class. However, nursing philosophy classes are essential for uncovering the academic foundations of nursing science, fostering creative insights, and navigating the actual clinical fields. This is particularly crucial because nurses frequently encounter numerous ethical dilemmas and critical decision-making situations. Nursing philosophy classes should be mandated as a required course for nursing graduate students, as they are responsible for shaping the future of nursing scholars.

        Purpose: The purpose of this study is to understand the general nurses's experiences of missing patient identification. Methods: Participants were 12 nurses who experienced missing patient identification in general wards in hospitals. Data were collected with focus group interviews and individual in-depth interviews and data were analyzed using qualitative content analysis. Results: As the results of this study, 128 statements, 4 themes and 13 sub-themes were derived. The four themes derived were ‘Situations that we had not to check patient identification properly’, ‘Fear and pressure from the result of missing patient identification’, ‘Feeling guilty to the results of missing patient identification’and ‘Efforts to reassuring patient identification’. Conclusion: In order to prevent the failure of patient identification, we need specialized programs to cultivate patient safety culture not only for nurses, also patients and caregivers, and all departments of hospital. We also need institutional efforts and effective hospital investment and supports for accomplishing the goal.

        본 연구에서는 정삼투 중공사막 모듈에서 중공사막의 가닥을 비틀어 배치하였을 때의 효과를 알아보기 위해 CFD 전산 유체 역학 프로그램을 통해 5개의 다른 각도로 비틀린 중공사막 모듈을 설계하고 시뮬레이션하여 비틀리지 않은 모듈과 비교하였다. 실험 결과, 중공사막이 비틀렸을 때, 모듈 내부의 유도 용액의 농도가 비틀리지 않을 때에 비해 고르게 분포하였 다. 모듈 입구의 압력은 중공사막의 비틀림과 관계없이 일정한 값을 보였지만 출구의 압력은 중공사막이 비틀린 정도가 커질 수록 증가하는 추세를 보였다. 출구의 압력이 높아짐에 따라 막 내부의 유체 속도가 감소하고 모듈 체류 시간이 증가하여 막 사이의 물질 교환이 원활하게 이루어질 것으로 예측된다. 이는 결과적으로 막이 비틀려 있을 때의 모듈 플럭스가 투과 수량 이 차지하는 비율이 그렇지 않을 때에 비해 2배 증가하였다.

        Morphology of cumulus-oocyte-complexes (COCs) at germinal vesicle (GV) stage as one of the evaluation criteria for oocyte maturation quality after in vitro maturation (IVM) plays important roles on the meiotic maturation, fertilization and early embryonic development in pigs. When cumulus cells of COCs are insufficient, which is induced the low oocyte maturation rate by the increasing of reactive oxygen species (ROS) in porcine oocyte during IVM. The ROS are known to generate including superoxide and hydrogen peroxide from electron transport system of mitochondria during oocyte maturation in pigs. To regulate the ROS production, the cumulus cells is secreted the various antioxidant enzymes during IVM of porcine oocyte. Our previous study showed that Mito-TEMPO, superoxide specific scavenger, improves the embryonic developmental competence and blastocyst formation rate by regulating of mitochondria functions in pigs. However, the effects of Mito-TEMPO as a superoxide scavenger to help the anti-oxidant functions from cumulus cells of COCs on meiotic maturation during porcine oocyte IVM has not been reported. Here, we categorized experimental groups into two groups (Grade 1: G1; high cumulus cells and Grade 2: G2; low cumulus cells) by using hemocytometer. The meiotic maturation rate from G2 was significantly (p < 0.05) decreased (G1: 79.9 ± 3.8% vs G2: 57.5 ± 4.6%) compared to G1. To investigate the production of mitochondria derived superoxide, we used the mitochondrial superoxide dye, Mito-SOX. Red fluorescence of Mito-SOX detected superoxide was significantly (p < 0.05) increased in COCs of G2 compared with G1. And, we examined expression levels of genes associated with mitochondrial antioxidant such as SOD1, SOD2 and PRDX3 using a RT-PCR in porcine COCs at 44 h of IVM. The mRNA levels of three antioxidant enzymes expression in COCs from G2 were significantly (p < 0.05) lower than COCs of G1. In addition, we investigated the anti-oxidative effects of Mito-TEMPO on meiotic maturation of porcine oocyte from G1 and G2. Meiotic maturation and mRNA levels of antioxidant enzymes were significantly (p < 0.05) recovered in G2 by Mito-TEMPO (0.1 μM, MT) treatment (G2: 68.4 ± 3.2% vs G2 + MT: 73.9 ± 1.4%). Therefore, our results suggest that reduction of mitochondria derived superoxide by Mito-TEMPO may improves the meiotic maturation in IVM of porcine oocyte.
