Objectives: The study aims to examine the influence of university students' sociodemographic variables, parents' variables, and personal variables on their level of depression. Method: The study included a total of 334 university students enrolled in Busan. The data were used to perform correlational analysis and hierarchical regression analysis and were processed using the SPSS 23.0 program. Results: The main results of this study were as follows: First, the hierarchical regression analyses revealed that the most influential model was the model of personal variables. Among the personal variables, self-esteem was the most influential factor responsible for university students developing depression - the higher their level of self-esteem, the lower their level of depression. Among the parent variables, attachment to their father was the second most significant influence on the depression level of university students. Conclusions: This study showed that, in addition to attachment to their father, their self-esteem was highly significant in predicting university students' depression. The results of these findings have implications for future research in the form of programs and education to improve the relationship with fathers. Furthermore, the results of this study could be used to help and provide basic resources to alleviate and prevent university students' depression by strengthening their self-esteem.

In this paper, learning capabilities of two types of Arterial Neural Networks, namely hierarchical neural networks and Generalized Regression Neural Network were used in a two-stage approach to develop a method for generating spatial varying accelerograms from acceleration response spectra and a distance parameter in which generated accelerogram is desired. Data collected from closely spaced arrays of seismographs in SMART-1 array were used to train neural networks. The generated accelerograms from the proposed method can be used for multiple support excitations analysis of structures that their supports undergo different motions during an earthquake.

생존분석 회귀모형에서 적절한 변수를 선택하는 것은 매우 중요하다. 본 논문에서는 "frailtyHL" R 패키지 (Ha 등, 2012)를 기반으로 하여 다수준 프레일티 모형 (multi-level frailty models)에서 벌점화 변수선택 방법 (penalized variable-selection method)의 절차를 소개한다. 여기서 모형 추정은 벌점화 다단계 가능도에 기초하며, 세 가지 벌점 함수 (LASSO, SCAD 및 HL)가 고려된다. 개발된 방법의 예증을 위해 벨기에 EORTC (European Organization for Research and Treatment of Cancer; 유럽 암 치료기구)에서 수행된 다국가/다기관 임상시험 자료를 이용하여 세 가지 변수 선택 방법의 결과를 비교하고, 그 결과들의 상대적 장 단점에 대해 토론한다. 특히, 자료 분석 결과에 의하면 SCAD와 HL방법이 LASSO보다 중요한 변수를 잘 선택하는 것으로 나타났다.

Today's health care environment is rapidly changing and nurse administrators' leadership styles need to identify in nursing organization to achieve organizational objectives. By Bass(1985), transformational leadership stimulates the subordinates to be creative and achieve organizational objectives and is related to job satisfaction, job involvement, productivity, and organizational commitment. Transformational leadership process consists of charisma, intellectual stimulation, individual consideration. The purpose of this study is to identify the effect of transformational leadership and personal characteristics on nurses' organizational commitment. The subjects for this study consisted of 594 nurse from 8 University Hospitals and General Hospitals. The data were collected by personal characteristics scale, transformational leadership scale, and organizational commitment scale. The factor analysis, Cronbach's alpha analysis, Pearson correlation analysis, multiple regression analysis and hierarchical multiple regression analysis were used for the statistical method. The results of this study were found that (1) charisma dimension of transformational leadership has positive influence on nurses' organizational commitment; but another two dimensions(intellectual stimulation and individualized consideration) did not showed significant effect on organizational commitment (2) nurses' personal characteristic(internal locus of control) moderated the effect of transformational leadership on organizational commitment.

Purpose: The purpose of this study was to identify factors with nursing students's confidence in performing fundamental nursing skills. The focus was on professionalism and self-efficacy. Method: For the sample 258 fourth graders of nursing students were recruited in two universities located in Gyeongnam or Ulsan. Data were analyzed using t-test, Pearson's correlation coefficients, and hierarchical multiple regression. Results: The mean score for confidence in performing fundamental nursing skills was $3.71{\pm}0.58$. Nursing professionalism and self-efficacy were positively correlated with confidence in performing fundamental nursing skills. Analysis using multiple regression showed that 27% of factors predicting confidence in performance of fundamentals of nursing practice (F=16.43, p<.001) included nursing professionalism (${\beta}=.37$, p<.001), self-expression (${\beta}=.15$, p=.009), and self-efficacy (${\beta}=.14$, p=.029). Conclusion: Findings show that nursing professionalism is one of the major factors influencing confidence in performing fundamental nursing skills. In order to improve the confidence in performing fundamental nursing skills, it is necessary to establish effective educational strategies that firmly enhance nursing professionalism and improve self-efficacy in nursing students.

미결정자 추론을 재평가하기 위해 기존 변수에 새로운 변수들을 추가하는 통계 모형이 필요하다. 미결정자와 결정자의 양성률은 다르게 계산되기 때문에 MNAR 가정이 필요하다. 본 연구에서는 두 통계적 모형이 계층 관계를 가지고 있으므로, 두 AUC 차이의 신뢰구간을 이용하여 MNAR 가정하에서 미결정자를 추론한다. AUC 차이 신뢰구간의 추정방법 중에서 모의실험을 통하여 네 종류의 방법의 성능이 우수함을 발견하였다. 그리고 네 종류의 방법을 바탕으로 로지스틱 회귀를 이용한 미결정자 추론에 도움이 되는 변수를 선택하는 방법을 제안한다.

Purpose: This study aimed to identify the infant-rearing experiences of parents during the coronavirus disease 2019 (COVID-19) pandemic and provide foundational data for the development of infant-rearing support programs during pandemic situations. Methods: Convergent mixed methods were used to better understand the research outcomes by converging both quantitative and qualitative data. A total of 149 parents with infant-rearing experiences during the pandemic responded to a self-report survey, and 10 parents participated in the interviews. Data were analyzed using Colaizzi's method, descriptive statistics, t-test, one-way analysis of variance, the Scheffé test, Pearson correlation coefficients, and hierarchical regression. Results: Analysis of qualitative data yielded the following three categories: five theme clusters, ten themes, and thirty-nine subthemes. The factors influencing infant-rearing behavior were nuclear family (β=.34, p<.001) and rearing stress (β=-.39, p<.001). The explanatory power of the regression equation was 26.6%. Conclusion: Infectious disease disasters, such as the COVID-19 pandemic, can quickly alter infant-rearing conditions, causing heightened parental anxiety. This may affect infant-rearing behaviors and hinder healthy infant development. Future research should develop a comprehensive tool to measure holistic health-related parenting behaviors across the different stages of child development. Additionally, pediatric nurse practitioners can play an active role in educating parents, supporting parenting, and promoting healthy infant development in their communities, making pediatric nurse practitioners a highly relevant and necessary healthcare profession during infectious disease disasters. Thus, there is a need to improve institutions and build infrastructure at the national level to support them.

이 연구의 목적은 포스트 코로나 시대에 있는 대학생들의 스트레스 대처방법이 여가제약협상에 어떻게 영향을 미치는지를 살펴보는 것이다. 이 연구의 목적을 달성하기 위하여, 2021년 1월 25일부터 2월 19일까지 전북, 전남, 부산에 소재한 대학생을 대상으로 설문조사를 실시하여 총 247명의 자료를 분석에 사용하였다. 자료분석은 SPSS 21.0과 AMOS18.0 을 사용하여 기술통계, 확인적 요인분석, ANOVA와 위계적 회귀분석을 실시하였다. 그 결과 COVID-19 이전과 이후의 여가유형에 변화에 따라 여가제약협상에 차이가 나타났다. 대학생들의 스트레스 대처방법에 따라 여가제약협상에 대한 부분에 긍정적인 영향을 미치는 것으로 나타나 대처방안에 대한 세부적 접근에 대해 고민해야 할 것이다. 특히 스트레스 대처방법 중 적극적인 스트레스 대처방법(문제중심 대처, 사회적지지추구)이 여가제약협상에 긍정적 영향을 미치고 있음을 확인 할 수 있었다. 따라서 COVID-19와 연계하여 스트레스 대처와 연계한 여가제약이나 여가만족 등 다각도의 접근이 필요 할 것으로 판단된다.
