  • This tutorial explains that the static effect in the magnetotelluric (MT) survey is a physical phenomenon caused by charges accumulated on the boundaries of subsurface inhomogeneities. To facilitate understanding of the physical phenomenon, differences between static induction and charge accumulation on the boundary are explained and analyzed with help of schematic illustrations. Subsequently, from the electromagnetic (EM) integral equation formulation, it is clearly shown that the secondary electric field due to charges accumulated on the interface in the presence of the primary field appears as the static effect. Therefore, except in the cases of the layered earth or a two-dimensional earth with transverse magnetic (TM) mode excitation, the static effect always exists in MT responses and further, it is not 'static' but rather frequency dependent. Despite the fact that the static effect is a secondary electric field due to inhomogeneity, inevitable under-sampling in the frequency and spatial domains prevent the effect from being handled properly in numerical inversion. Therefore, considering the practical aspects of the MT survey, which cannot be a continuous measurement covering the entire survey area over a wide frequency band, a three-dimensional (3-D) inversion incorporating the static shift as a constraint with the Gaussian distribution is introduced. To enhance understanding of the integral equation EM modeling, the formulation of the 3-D integral equation and mathematical analyses of the Green tensor and scattering current are described in detail in the Appendix.

  • This study was conducted to identify factors influencing clinical performance among nursing students who experienced clinical practice due to COVID-19 and provide basic data to improve clinical performance. This study collected data from October 10 to October 27, 2023, targeting 144 students at two nursing schools in G Province. The collected data were analyzed using descriptive statistics, difference analysis (t-est, on-way ANOVA), correlation, and hierarchical regression analysis. As a result of the study, in Model 1, extrovert and mixed personality types were found to be significant predictive factors explaining clinical performance. The goodness of fit of Model 1 was statistically significant, and the explanatory power was 9.2% (F=8.256, p<.001). In Model 2, interpersonal skills and confidence in nursing skills appeared as significant predictive factors explaining clinical performance ability. Confidence in nursing skills was the best predictor of clinical performance, followed by interpersonal skills. The explanatory power of the model was 50.1%, an increase of 41.3% compared to Model 1. Model fit was also statistically significant. Simulation education that reproduces various situations should be strengthened to increase opportunities to perform direct nursing and improve nursing students' nursing capabilities. If you improve your confidence in nursing skills and interpersonal skills through simulation education, your clinical performance will ultimately improve, and this will be able to be demonstrated as a nursing competency when employed as a nurse.

  • This case study aimed to develop a therapeutic rap protocol based on narrative components for improving discourse skills of adolescents with mild intellectual disability (ID) and to explore its applicability. The protocol matched narrative elements (background, initiating event, internal response, attempts, and reaction) with rap components (verse, hook, and interjections), guiding participants to narrate their experiences in a connected discourse form. The protocol was also structured to gradually increase in difficulty, considering the developmental levels of adolescents with ID and it included steps for understanding discourse structures, applying narrative elements to content creation, and expanding narratives. Post-intervention analysis of the stories and rap lyrics created by participants to express their real-life experiences showed that participants increased the length of their stories and rap compositions, with notable improvements in rhythmicity and the inclusion of narrative elements. These findings suggest that, instead of constructing rap from random utterances, providing a structured framework reflecting discourse structure enhanced participants' understanding of event context and logical connections. Furthermore, the various elements and rhythmic features of rap can strengthen motivation and organization in discourse. This study highlights the therapeutic potential of rap in addressing the unique developmental needs of adolescents with mild ID, thereby diversifying and systematizing music therapy interventions for this population.

  • Purpose: This study is a comparative study conducted to examine the differences in attitudes toward COVID-19 prevention, self-leadership, and infection prevention behaviors among nursing students based on their experience in community volunteer related to infection disease prevention. Method: A total of 286 nursing students (146 in the experimental group and 140 in the control group) from 14 regions across the country were conveniently sampled from November 1 to 30, 2021, and the average difference in each variable according to participation in volunteer activities was analyzed using a t-test. Results: The comparison of differences based on participation in volunteer activities showed that the group with volunteer experience had a statistically significantly higher score in all variables: attitudes toward COVID-19 prevention (42.25±5.35 points) compared to those without experience (40.02±6.30 points)(p=.001), self-leadership (72.04±13.18 points) compared to those without experience (66.58±10.85 points)(p<.000), and infectious disease prevention behavior (44.31±7.62 points) compared to those without experience (39.38±7.20 points)(p<.000). Conclusion: This study provides practical and educational implications by suggesting a direction for educating nursing students who will need to provide actual care in future infectious disease outbreaks. These results suggest that nursing students could carry out volunteer service related infection diseases prevention through customized education and promotion programs for different target groups, which could be supported by school budgets, club activities, or incorporated into regular courses. Furthermore, it can be utilized as foundational data for the development of future nursing education programs

  • Yeong-dae(靈臺), Yeong-yu(靈囿), and Yeong-so(靈沼) - so-called 'Yeong-dae Garden' – appear in the poem 'Dae-ah(大雅)․Yeong-dae(靈臺)' in Shijing(詩經) which is considered the record of the earliest garden in East Asia, in the chapter 'Yanghyewang(梁惠王)' of Mencius(孟子). Focusing on those records, this research clarifies their characteristics and discusses the aspects related to garden practices in the Joseon Dynasty. The Yeong-dae Garden is the garden of King Wen of the Zhou Dynasty, who is considered a sage of Confucianism. It is considered to be the first imperial garden in China, and the basic form of all gardens consists of mountains and water. The characteristics of Yeong-dae Garden can be specified through the texts of Shijing and Mencius, the comments written by Zhu Xi and others, and later literature, such as Sambohwangdo. The characteristics of Yeong-dae Garden are as follows: In terms of form, the three spatial elements corresponding to raised ground, a wide area for raising animals, and a pond with fish form a simple arrangement; in terms of function, it combines observation and rest; and in terms of symbolism, it signifies the companionship of the public sentiment and the leader's sincerity. In literature from the Joseon Dynasty, Yeong-dae Garden mainly appear in historical materials related to the King, and its meaning shows an aspect of differentiation into two functions: an observatory for astronomical observation and a garden for rest and appreciation. For the intellectuals of Joseon who sought to restore an ancient ideal state like the Zhou Dynasty through Zhu Xi's Neo-Confucianism, the Yeong-dae Garden served as a control device to warn against royal garden's practices and a symbolic mechanism to expand its meaning of existence to good politics.

  • This study is a descriptive research to determine the mediating effect of Positive Psychological Capital on the relationship between Job Stress and Retention Intention among nurses working at blood centers in the metropolitan area. Data were collected from 167 nurses using a structured questionnaire between May 2021 and April 2022, and analyzed by SPSS ver.25. General characteristics were analyzed through frequency, percentage, mean, and standard deviation. The relationship between Job Stress and Retention Intention was analyzed using independent samples t-test, ANOVA, and Pearson's correlation. Hypotheses were tested using hierarchical multiple regression analysis and PROCESS macro model 4. The results substantiated the hypotheses: Hypothesis 1 proposed that higher Retention Intention and Positive Psychological Capital were associated with lower Job Stress. Hypothesis 2 suggested that Positive Psychological Capital significantly partially mediates the relationship between Retention Intention and Job Stress. To promote Retention Intention among blood center nurses, it is crucial to implement human resource management systems aimed at alleviating Job Stress and enhancing Positive Psychological Capital. Specifically, enhancing Positive Psychological Capital within blood centers is particularly significant. This study contributes empirical evidence necessary for efficient personnel management and competency enhancement programs to reduce Job Stress, thereby enhancing the quality of nursing care among blood center nurses. Furthermore, it is recommended to develop intervention programs for Positive Psychological Capital to enhance Retention Intention and reduce Job Stress among blood center nurses.

  • This study was a descriptived research study to determine the impact of empathy, communication competence, and personality on college adaptation among nursing students attending a university in City Y. The research method was a self-administered survey targeting 200 nursing students at a university in Y City, and data were collected from April 29, 2024 to May 27, 2024. The research statistical method used was the SPSS/WIN 25.0 statistical program, and was analyzed using t-test, one-way analysis of variance, Pearson correlation, and multiple regression analysis. In the correlation between each variable, college adaptation is related to empathy(r=.522, p<.001), communication competence(r=.557, p<.001), and personality(r=.561, p<.001). And as a result of regression analysis, as a factor affecting the subjects' college adaptation, second-year students(β=-.148, p=.013) had a higher level of college adaptation than first-year students(β=-.297, p<.001). Additionally, the level of college adaptation was high in the order of empathy(β=.295, p<.001), personality(β=.230, p<.001), and communication competence(β=.157, p=.050), and the explanatory power was 47.6%(Adj R2=.476, p<.001). Therefore, in order for nursing students to adapt to college, various psychological and emotional supports must be provided at the school and department level, and various customized programs that can improve empathy, communication competence, and personality should be developed and applied by considering the characteristics of nursing students by grade.

  • The Wisdom of Royal Glory (Kutadgu Bilig) is a Karakhanid work from the 11th century written by Yusuf Khass Hajib. Translated, the title means something like "The Wisdom which brings Happiness" or "The Wisdom that Conduces to Royal Glory or Fortune" or "Wisdom Which Brings Good Fortune". The text reflects the author's and his society's beliefs, feelings, and practices with regard to quite a few topics, and depicts interesting facets of various aspects of life in the Karakhanid empire. So the famous Chinese writer Lao she once pointed out that "it is not only the Uyghur's precious heritage, is also a priceless art treasures of our country's culture history." This paper mainly discusses about the variety of religious thought, such as primitive belief(teng ge li worship, natural worship, animal worship, shamanism), Manichaeism, Buddhism, Islam, etc.

  • This paper examined the understanding of the laws and punishments of Zhu Xi School. Zhu Xi of Nan-song(南宋) is a scholar who influenced many later East Asian countries, including Joseon. When limited to Joseon, various academic and political thought used Zhu Xi's interpretation as a standard. Thus it is necessary to study Zhu Xi's thought of law to comprehend the Confucian countries. However, there are a few previous studies that deal with the legal ideas of Zhu Xi. In order to understand Zhu Xi's perception of the law, this paper will analyze the Book of History(書經) as a central text. The Book of History describes the system and the law of ancient China. It also deals with the origin and development of punishment and legislation, unlike other scriptures. However, Zhu Xi died before he finished his work, making a footnote of the Book of History. Following his work, Cai Shen(蔡沈) completed the interpretation of the Book of History. Therefore, it would be natural to think Zhu Xi and Cai Shen were in continuity. This paper figures out the recognition of Zhu Xi School on punishment and law by organizing the history of punishment and law in the Book of History. Furthermore, analyzes other papers of Zhu xi to know his perception of law and punishment.

  • This study is a descriptive research study conducted to verify the dual mediating effect of critical thinking disposition and core nursing skill performance confidence in the relationship between clinical nurses' nursing professionalism and clinical decision-making ability and to use it as basic data for improving clinical decision-making ability. The study subjects were 173 clinical nurses at a general hospital in a region, and data were collected from September 15 to October 13, 2023. Data were analyzed using the SPSS/AMOS 23.0 program to verify the mediating effect by analyzing the causal relationship between the research variables and the bootstrapping estimation method, and t-test, ANOVA, Scheffe's test, Pearson's correlation coefficient, and hierarchical regression were performed. The results of the study include: First, the appropriateness of the causal model between clinical nurses' nursing professionalism, clinical decision-making ability, critical thinking disposition, and core nursing skill performance confidence was valid. Second, critical thinking disposition showed a partial mediating effect in the relationship between nursing professionalism and clinical decision-making ability. Third, as a result of verifying the dual mediating effect, the indirect effect of critical thinking disposition was greater than the indirect effect of critical thinking disposition and core nursing skill performance confidence, indicating that the single mediating effect was greater than the dual mediating effect. Therefore, it was verified that fostering high nursing professionalism in clinical nurses can improve clinical decision-making ability, and in particular, strengthening critical thinking disposition is more effective.
