  • Purpose: This study aimed to understand the experiences of women under 40 years of age with gynecologic cancer. Methods: Semi-structured individual in-depth interviews were conducted with 14 Korean female patients aged 21~39 years with gynecologic cancer. The data were analyzed using Corbin and Strauss' grounded theory approach, including open coding, context analysis, and integrating categories. Results: Grounded theory analysis revealed nine categories and a core category of 'the journey to find my life after losing the life as a typical woman.' The categories that emerged as the conditions are 'Unwelcomed guest, cancer,' 'Completely devastated life as an ordinary woman,' 'Uncertain future,' 'Losing my physical characteristics as a woman,' and 'Life tied with treatments.' The actions/interactions were 'Decrease of interpersonal relationships,' 'A lonely battle to overcome alone,' and 'The power to overcome hardships.' The consequence was 'Live my own life.' Conclusion: This study contributes to the development of a substantive theory of the experience of gynecologic cancer in young women, which has been on the rise in recent years. The study's results are expected to be used as a basis for providing nursing care to help young women with gynecologic cancer adapt to their disease.

  • Flight instructors at aviation training centers are exposed to various stresses, such as stress caused by special work environments, stress caused by working conditions, and stress related to uncertain future airline employment. These stresses are expected to not only affect flight safety, but also adversely affect the job satisfaction of flight instructors, and consequently negatively affect the performance of high-quality flight education. Therefore, this study was conducted to understand the effects of these stresses on the job satisfaction of flight instructors by examining the stress experienced by flight instructors in flight, psychological, and physical aspects based on the results of previous studies on stress. To the end, this study conducted a survey of flight instructors belonging to aviation training centers, and as a result of analyzing the collected data, it was confirmed that the physical stress of flight instructors had a significant negative effect on their job satisfaction.

  • The purpose of this paper is to consider the expansion of non-traditional security threats and the national-level response to the emergence of emerging security threats in ultra-uncertain VUCA situations. As a major research method for better analysis, the theoretical approach was referred to papers published in books and academic journals, and technical and current affairs data were studied through the Internet and literature research. The instability and uncertainty of the international order and security environment in the 21st century brought about a change in the security paradigm. Human security emerged as the protection target of security was expanded to individual humans, and emerging security was emerging as the security area expanded. Emerging security threatsthat have different characteristicsfrom traditionalsecurity threats are expressed in various ways, such as cyber threats, new infectious disease threats, terrorist threats, and abnormal climate threats. First, the policy and strategic response to respond to emerging security threats is integrated national crisis management based on artificial intelligence applying the concept of Foresight. Second, it is to establish network-based national crisis management smart governance. Third, it is to maintain the agile resilience of the concept of Agilience. Fourth, an integrated response system that integrates national power elements and national defense elements should be established.

  • Purpose: The popularity of social media has altered how customers interact with businesses, and an increasing number of customers prefer to voice their complaints on social media. Bystanders can observe the customer complaint process on social media, but the impact of transparency on bystanders remains uncertain. Therefore, this study established and verified a model for defining the effect of transparency and service recovery types on bystanders. Research Design and Methodology: In this study, we used the internet survey platform "So Jump" to collect data. And we validated three studies with SPSS 26.0 and Smart PLS 4.0. Result: First, we showed that the transparency process (vs. result) is more likely to increase customer forgiveness and E-loyalty and reduce E-NWOM intention among bystanders. Second, customer forgiveness also plays a complementary mediating role between transparency and E-loyalty, as well as between transparency and E-NWOM intention. Finally, we found a modest interaction effect between transparency (process vs. result) and service recovery types (psychological vs. tangible vs. hybrid) on bystanders' customer forgiveness and E-loyalty. Conclusions: This study provides actionable recommendations for how service managers can effectively employ social media as a means for distributing feedback information to manage service recovery in the future.

  • Target detection (TD) is a research hotspot in the field of hyperspectral imaging (HSI). Traditional TD methods often mine targets from HSIs under a single imaging condition, without considering the influence of imaging conditions. In fact, the spectra of ground objects in HSIs are uncertain and affected by the imaging conditions (weather, atmospheric, light, time, and other angle conditions including zenith angle). Hyperspectral data changes under different imaging conditions. Therefore, the detection result for a single imaging condition cannot accurately reflect the effectiveness of the detection method used. It is necessary to analyze the performance of various detection methods under different imaging conditions, to find a more applicable detection method. In this paper, we study the performance of TD methods under various land-based imaging conditions. We first summarize classical TD methods and evaluation methods. Then, the detection effects under various imaging conditions are analyzed. Finally, the concepts of the stability coefficient (SC) and effective area under the curve (EAUC) are proposed to comprehensively evaluate the applicability of detection methods under land-based imaging conditions, in terms of both detection accuracy and stability. This is conducive to our selection of detection methods with better applicability in land-based contexts, to improve detection accuracy and stability.

  • Objectives: Weight counseling is an inevitable process for patients with obesity who intend to lose weight; however, the contents of real-world counseling practices remain uncertain in Korean medicine (KM) practice. This study aimed to explore the structure and constituents of obesity counseling in KM. Methods: Qualitative methods were used to explore the structure of weight counseling and clinicians' approaches to weight counseling, particularly the advice and main constituents of weight counseling in KM. Nine KM clinicians (4 women, 5 men) from nine clinics completed face-to-face, individual and semi-structured interviews from September 2019 to February 2020 in Seoul, Daejeon, Cheonan, Seongnam, Asan, and Hwaseoug. The interviews were digitally recorded, transcribed verbatim, and categorized based on their constituents. Results: During weight loss counseling, the six principal constituents of KM identified were: planning with patients, motivation, correcting misinformation on weight loss, dietary and exercise advice, medication guidance, and customized guides for each type. Conclusion: Clinicians with in-depth knowledge about obesity prescribed personalized guidance for exercise, diet, and medication through an integrative approach. The study results provide an in-depth understanding of weight counseling in KM. These six constituents could guide the counseling provided by clinicians in obesity care.

  • Purpose: This study aimed to clarify the concept of pediatric hospice and palliative care through conceptual analysis. It also sought to identify the differences between related concepts such as pediatric death care and pediatric spiritual care, in order to provide foundational data for the development of nursing theory and knowledge. Methods: A conceptual analysis of pediatric hospice and palliative care was conducted using Rodgers' evolutionary method. Out of 5,013 papers identified, 28 were selected for detailed reading and analysis. Results: Pediatric hospice and palliative care encompasses physical, psychological, social, mental, spiritual, and family care for children with acute and chronic diseases with uncertain prognoses ahead of death, as well as their families. Effective pediatric hospice and palliative care will require multidisciplinary team nursing, effective communication, and supportive policies. Conclusion: The findings of this study suggest that providing pediatric hospice and palliative care will lead to improvements in pain relief for children and families, the efficiency of responses to death in children, and the quality of life for children and families. The significance of this study is that it clearly clarifies the concept by analyzing pediatric hospice and palliative care using an evolutionary method.

  • Artificial intelligence (AI) techniques are now being considered in the nuclear field, but application faces with the lack of actual plant data. For this reason, most previous studies on AI applications in nuclear power plants (NPPs) have relied on simulators or thermal-hydraulic codes to mimic the plants. However, it remains uncertain whether an AI model trained using a simulator can properly work in an actual NPP. To address this issue, this study suggests the use of metadata, which can give information about parameter trends. Referred to here as robust AI, this concept started with the idea that although the absolute value of a plant parameter differs between a simulator and actual NPP, the parameter trend is identical under the same scenario. Based on the proposed robust AI, this study designs an event diagnosis algorithm to classify abnormal and emergency scenarios in NPPs using prototypical learning. The algorithm was trained using a simulator referencing a Westinghouse 990 MWe reactor and then tested in different environments in Advanced Power Reactor 1400 MWe simulators. The algorithm demonstrated robustness with 100 % diagnostic accuracy (117 out of 117 scenarios). This indicates the potential of the robust AI-based algorithm to be used in actual plants.

  • The release source term of radioactivity becomes a critical foundation for emergency response and accident consequence assessment after a nuclear accident Rapidly and accurately inverting the source term remains an urgent scientific challenge. Today source term inversion based on meteorological data and gamma dose rate measurements is a common method. But gamma dose rate actually includes all nuclides information, and the composition of radioactive nuclides is generally uncertain. This paper introduces a novel nuclear accident source term inversion model, which is Improve Snow Ablation Optimizer-Sensitivity Analysis Pruning Extreme Learning Machine (ISAO-SAELM) model. The model inverts the release rates of 11 radioactive nuclides (I-131, Xe-133, Cs-137, Kr-88, Sr-91, Te-132, Mo-99, Ba-140, La-140, Ce-144, Sb-129). It does not require the use of the physical field of the reactor to obtain prior information and establish a dispersion model. And the robustness is validated through noise analysis test. The mean absolute errors of the release rates of 11 nuclides are 15.52 %, 15.28 %, 15.70 %, 14.99 %, 14.85 %, 15.61 %, 15.96 %, 15.42 %, 15.84 %, 15.13 %, 17.72 %, which show the significant superiority of ISAO-SAELM. ISAO-SAELM model not only achieves notable advancements in accuracy but also receives validation in terms of practicality and feasibility.

  • In order to find out the status of health care of the old aged people (age of 65 and over) in a rural area, a study was carried out, through analyzing the data of health care clinic for 207 old aged people with geriatric diseases, and of questionnired survey for 84 old aged people with geriatric diseases in a rural community. Su Dong-Myun. Nam Yang Zu-Gun, Kyung Gi-Do, Korea, during the year of 1989. The following results were obtained. 1) The composition rate of population of age of 65 and over was 9.8% in total, and sex-specific composition rate was 9.3% in male and 10.4% in female. 2) Utilization rate of health care clinic for old aged people with geriatric diseases was the highest rate with 37.9%, through individual letters at the first time, and showed gradually decreasing tendency afterward. 3) In the means of utilization advices to health care clinic for the old aged people. the individual letters(37.9%) at the first time were more effective than public information of the old aged hall or/and Myun office(18.4%). 4) In opinion on utilization of health subcenter-health care clinic for the old aged people "will utilize"(59.5%) was the highest and "do not know"(26.2%) "be difficult to utilize" (9.5%) and "will not utilize"(4.8%) were in the next order. 5) Out of 84 respondents, the old aged people With geriatric diseases, 73.8%(about three-fourths) of them answered "their diseases to the aggravated" (29.8%) "not to be changed"(25.0%) and "to be unknown"(19.0%), and the others(26.2% of them) "to be changed for the better". 6) Out of 62 respondents(the old aged people), answered their geriatric diseases not to be changed for the better, "no curative effect" was the highest with 43.5% of them. "could not know" (33.9%), "would not treat"(19.4%) and "could not be treated"(4.8%) were in decreasing order. 7) The old aged people, responded their diseases to be changed for the better, answered that they(patients) should make themselves(68.2%) responsible for basic effort of health care. However the old aged people responded their diseases not to be changed for the better answered that they should impute the responsibility of basic effort for health care to medical facilities or other conditions(63.0%). 8) In the reason of failure that the old aged people responded their geriatric diseases not to have curative effect, mis-control of regular habits of daily life was the highest(57.1%), and failure of taking selected medicine steadily(28.6%), and abuse of medicines(14.3%) were in decreasing order. 9) The reason order of being changed for the better that the old aged people responded their diseases to have curative effect, was keeping and control of regular habits of daily life (46.7%), taking selected medicines steadily(33.3%) and others (20.2%) respectively. 10) The courses of geriatric diseases itself are so chronic, duplicate and uncertain, and the old aged people activities for disease control are so slow, various and uncertain that continuous health education in home or/and community unit must be essential factors for effective geriatric health care.
