Symbolic data analysis extends the data mining and exploratory data analysis to the knowledge mining, we can suggest the SDA tree model on clinical and genomic data with new knowledge mining SDA approach. Using SDA application for huge genomic SNP data, we can get the correlation the availability of understanding of hidden structure of HCC data could be proved. We can confirm validity of application of SDA to the tree structured progression model and to quantify the clinical lab data and SNP data for early diagnosis of HCC. Our proposed model constructs the representative model for HCC survival time and causal association with their SNP gene data. To fit the simple and easy interpretation tree structured survival model which could reduced from huge clinical and genomic data under the new statistical theory of knowledge mining with SDA.

In this study, an attempt was made to investigate the clinical reasoning of nursing students and to identify the factors that influence it. This study was held to grasp the learning ability related to core nursing competency for 297 3^rd and 4^rd grade nursing students. Results indicated that there was a significant difference when comparing clinical competence by grade(p=0.001). Also variables effecting clinical reasoning competence were Problem solving ability, Clinical Decision making ability, Clinical practice performance, and grade of nursing students were found to be significant (p,.001). Outcome of this study can be used as the basis for the development of various curriculums to enhance the clinical reasoning competence, in the future, research for this education development is expected to be needed.

Purpose: The purpose of this study was to investigate relationship among self-directed learning, confidence of performance, clinical learning environment and Clinical Competency of nursing students. Methods: 178 nursing students participated. Data analysis was performed using descriptive statistics, t-test, ANOVA and pearson's correlation coefficients with IBM SPSS Statistics 21.0. Results: Mean score of self-directed learning, confidence of performance, clinical learning environment and clinical competency was 3.36, 3.42, 3.20 and 3.66 points. There was significant positive correlation among self-directed learning, confidence of performance, clinical learning environment and clinical competency. Conclusion: Therefore, in order to improve the clinical competency of nursing students, it is necessary to systematize core nursing skills education and continuously improve the clinical learning environment through close industry-academia cooperation and relationship.

There are lots of analysis to determine the relation between dependent variable and explanatory variables. Often the regression analysis is used to do this, and we can analyze the how much the explanatory variable can be related with dependent variable and how much the regression model can explain the data. But the validation check of regression model is usually determined by coefficient of determination. We should check the validation of regression coefficient with different methods. This paper introduces the method for validation check the regression coefficient using the jackknife regression and bootstrap regression in clinical data.

There was a report that the prevalence of gallbladder polyps (GBPs) and some clinical variables were different between the urban and rural area, which was performed in a mainland. Thus the previous report could have some confounding factors. Therefore, the purpose of this study was to compare the prevalence of GBPs and clinical variables on the isolated island to exclude extrinsic confounding factors. We compared the prevalence of GBPs and clinical variables among 21,734 residents who visited a single medical check-up center in Jeju National University Hospital from January 2010 to December 2019 according to their residences on Jeju Island. The prevalence of GBPs were 10.1% in the urban area 8.7%, respectively (P = 0.006). Among clinical variables, the rate of central obesity, the mean levels of fasting blood glucose, low density lipoprotein-cholesterol, alkaline phosphate and gamma-glutamyltransferase and the mean age among residents in the rural area was statically higher in the urban area; however, the mean total cholesterol level among residents in the urban area significantly higher than in the rural area. This study showed that the prevalence of GBPs and some clinical variables among residents were statistically different between the urban area on Jeju Island.

Malassezia(Pityrosoprum) pachydermatis에 의한 피부염의 위험요인을 파악하고자 1997년 1월에서 1998년 12월까지 서울대학교 수의과대학 부속동물병원에 내원하여 본 질환으로 진단된 29두와 동일한 기간 동안 피부과 검사에서 임상적으로 건강한 개로 확인된 97 두의 대조군을 대상으로 분석하였다. 각 설명변수에 대한 교차비(odds ratio, OR)와 신뢰구간(confidence interval, CI)은 변수보정법을 사용하여 계산하였다. 다른 공변수를 보정한 상태에서 다중 로지스틱 회귀분석(multiple logistic regression analysis)을 시행한 결과 피부병기왕력(p=0.0059; OR, 4.44; CI, 1.5∼12.8)과 비만(p=0.0013; OR, 5.38; CI, 1.9∼14.9)은 유의한 위험요인으로 나타났다. 단변량 분석(univariate analysis)에서 주 사료로 고기를 섭취하는 경우 피부염의 위험이 높은 변수로 작용하였지만(p=0.0398; OR, 6.38; CI, 1.1∼37.3) 다른 공변수를 보정한 분석에서는 유의하지 않은 것으로 나타났다. 성별, 품종, 및 예방접종은 위험요인으로 작용하지 않았다.

모든 질병에서 피로감은 환자가 경험하는 매우 흔한 증상으로서 임상간호현장에서 쉽게 간과 되어져왔다. 최근까지 건강관련 학문분야에서 피로감에 관한 수많은 연구가 진행되어져 왔지만. 임상간호현장에 도움이 될 만한 연구결과, 즉 임상 간호사의 간호사정과 간호중재에 지침이 되는 연구는 부족한 현실이다. 구체적인 연구 계획에 앞서, 연구의 이론적인 배경과 근거, 이론에서 추출된 개념, 변수와 연구 도구들간의 전체적인 일관성이 매우 중요하다. 추상적인 이론으로부터 개념과 변수를 거쳐 연구에 직접 사용될 구체적인 연구도구를 일관성 있게 선택하는 일련의 과정을 'Theoretical Substruction'이라 한다. 심부정맥환자가 지각하는 피로감에 관한 연구에 앞서, 본 글을 통해 심부정맥과 피로감의 이론적인 연관성과 이 연구를 위한 개념과 변수, 구체적인 연구도구를 선택하는 과정, Theoretical Substruction에 대해 토의될 것이며, 이에 따른 연구질문도 제의 될 것이다.

The purpose of this research is to analyze converged factors affecting compassion competence in clinical nurses. This is a descriptive correlation research to examine converged factors affecting compassion competence of clinical nurses. Research objects are 233 nurses working in three general hospitals located in Chungnam province, and who understand the purposes of this research and agree to participate in this research. To analyze the data, descriptive statistics, t-test, ANOVA, Pearson's Correlation Coefficient, and stepwise multiple regression analysis were used. The variable which has the greatest effect on compassion competence was compassion satisfaction, followed by clinical experience, compassion fatigue, with those 3 variables explaining 34.4% of compassion competence. Therefore it is necessary to develop specific education programs to improve compassion competence of nurses. Since the explaining power of three variables to compassion competence is 34.4%, it is necessary to add more meaningful variables to explain compassion competence of clinical nurses.

This study is to understand the relationship between self-leadership, clinical competence, and clinical practice satisfaction of nursing students, and to investigate the effect of self-leadership and clinical competence on clinical practice satisfaction. Data collection was conducted from May 1 to May 16, 2019, and 186 questionnaires were used for analysis and analyzed through SPSS/WIN 28.0. The average of the participants's self-leadership was 3.44 points, the average of clinical competence was 3.82 points, and the average of clinical practice satisfaction was 3.69 points. Satisfaction with clinical practice was found to have a positive correlation with self-leadership(r=.221, p=.002) and clinical competence(r=.262, p<.001), and self-leadership and clinical performance(r=.050, p=.494) showed no correlation. The variables affecting clinical practice satisfaction were self-leadership(β=.251, p<.001) and clinical competence(β=.208, p=.003), and the explanatory power of these variables was 10.4%. Therefore, in order to increase the satisfaction of nursing students in clinical practice, it is necessary to develop a program that can improve self-leadership and clinical competence.

The present study examined the relationships of emotional labor, job satisfaction and burnout in medical technologists working at university hospitals. The study subjects were 145 medical technologists and health information technicians working at 4 university hospitals. The investigation was conducted using a standardized self-administered questionnaire from April 10-19, 2013. As a result of hierarchical multiple regression, the socio-demographic characteristics, health-related behavior factors, job-related factors, emotional labor and job satisfaction were selected as significant variables and related variables affecting the level of burnout. The descriptive power of these variables(socio-demographic characteristics, health-related behavior factor) was 21.7%, especially it can be seen that emotional labor and job satisfaction variable input 16.8% and 8.2% increase explanatory power respectively.
