This study aims to empirically identify the structural patterns of social support exchanged by cancer survivors in online communities and their unmet socio-economic needs during labor market reintegration, by analyzing YouTube vlog comments as a form of naturally occurring unstructured big data. As Korea's five-year cancer survival rate has reached 72.1%, cancer survivors increasingly face challenges of employment discontinuity and job instability, yet existing social safety nets fail to adequately address these needs. We collected 164,850 raw comments from 150 cancer survivor vlog videos posted between January 2020 and December 2024, employing a dual sourcing strategy combining YouTube Data API v3 and Selenium web drivers. Data collection was completed by February 2025, and preprocessing and analysis were finalized by November 2025. Following a four-stage preprocessing pipeline grounded in pilot-tested thresholds, 148,708 valid comments were analyzed using TF-IDF, Latent Dirichlet Allocation (LDA) topic modeling, binomial logistic regression, and KOSAC -based sentiment analysis. LDA topic modeling (K=5, coherence score Cv=0.52) revealed that ‘emotional solidarity and support’ constituted the largest latent topic (29.6%), demonstrating that cancer survivors prioritize emotional bonding over medical information exchange in online communities. Logistic regression confirmed that emotional support vocabulary significantly predicted empathic responses measured by comment ‘like’ counts (beta=1.847, p<.001), while medical information terms showed no statistical significance. Sentiment analysis revealed dominant positive sentiment (65%) with coexisting ambivalence structures in uncertainty-related topics. Theoretically, based on the observed complex support behaviors specific to vocational reintegration contexts, we propose ‘vocational rehabilitation support’ as a new subtype extending House's (1981) social support typology. From an industrial and systems engineering perspective, the findings provide an empirical foundation for designing return-to-work (RTW) process models and job redesign decision frameworks within human resource management (HRM) systems. Practically, we derive evidence-based policy recommendations including peer support programs, flexible work arrangements, and an incentive-penalty system modeled on Germany’s Schwerbehinderten-Ausgleichsabgabe.

The Stone Pagoda at Mireuksa Temple Site, Iksan, built during the reign of King Moo(武王) of Baekje(百濟), is one of the earliest stone pagodas in Korea. The main feature of the Stone Pagoda at Mireuksa Temple Site, Iksan is the technique of constructing the pagoda body using a technique of constructing stone structures that is difficult to find in China or Silla during the same period. In this study, we inferred that the origin of the Post & lintel construction technique of the stone pagoda of Mireuksaji Temple in Iksan came from the Post & lintel construction Stylobate of Baekje. As a result of comparing the part composition and joining method of the pagoda body and the Post & lintel construction stylobate, it was confirmed that the Post & lintel construction stylobate influenced the construction technique of the pagoda body. In addition, differences in the way the Post & linte construction technique is applied depending on the location of the pagoda body of Stone Pagoda at Mireuksa Temple Site, Iksan were inferred. This study is significant in that it clearly reveals the origin of the unique construction technique of the Stone Pagoda at Mireuksa Temple Site, Iksan.

As science and technology advance, the demand for materials capable of withstanding extreme environments has steadily been increasing. Among them, structural materials that can operate reliably at high temperatures remain a critical field of development. Single-crystal nickel-based superalloys are among the most advanced metallic materials, capable of sustaining stresses at the highest operating temperatures, and are widely used for gas turbine blades. Since the efficiency of a gas turbine increases with higher turbine inlet temperature, the development of alloys capable of operating under such extreme conditions has been a continuing challenge. Significant progress has been achieved by adding refractory elements such as Re and Ru, leading to superalloy generations classified according to their content. While advanced countries initially led the development of 4th and 5th generation alloys containing high amounts of Re and Ru, recent trends have emphasized cost competitiveness, by reducing these expensive elements while maintaining high-temperature performance. Alongside Western countries, China has also invested heavily in optimizing Re and Ru content for material self-reliance. For Korea, the local realization of single-crystal superalloys is essential not only for industrial gas turbines but also for defense-related jet engines. At the Korea Institute of Materials Science, extensive research has been carried out to develop alloys tailored to different conditions. Recently, a Re-free single-crystal superalloy was developed that exhibits superior creep resistance compared to conventional Re-containing alloys, even outperforming TMS-1700, the world-class Re-free alloy developed at NIMS, Japan. Optimization studies toward commercialization are ongoing, contributing to the national goal of self-reliance in extreme high-temperature materials.

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.
