This study investigates the relationships among academic stress, learning satisfaction, and learning flow of the health science college students who take online classes in college. The subjects were 129 students and the data were collected from November 15th, 2020 to December 22th, 2020 using a self-report structured questionnaire. The data analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation analysis, and multiple regression. As a result of this study, academic stress showed a negative correlation between learning satisfaction (r=.-78, p<.001) and learning flow (r=.-70, p<.001). And learning satisfaction showed a positive correlation between learning flow (r=.71, p<.001). In the results of multiple regression analysis, factors influencing the learning flow of students were amount of assignments in online classes, number of online practice courses completed in the last semester, academic stress, and learning satisfaction. All of these variables together explained 59.0%. Therefore, in order to increase learning flow in online classes, strategies to reduce academic stress and development of various educational programs are required.

This study was conducted to investigate the relationship between self-esteem, self-awareness, and empathy and to identify factors that influence empathy among 302 nursing students from a university in C city from March to May 2021. The collected data were subjected to t-test, ANOVA, correlation and multiple regression analysis. As a result of the study, empathy was 3.59 points out of 5, and gender and nursing department satisfaction were significantly different from empathy. The factors that had a significant effect on empathy were private self-awareness, public self-awareness, positive self-esteem, and gender, with the explanatory power of 22.9%. In order to increase the level of self-esteem, self-awareness and empathy for nursing students, it is necessary to establish a new curriculum that examines interest in their inner world. Development of various curriculum programs such as team classes that help promote interaction using small groups and role-playing classes that explore and experience one's own or others' thoughts and emotions are suggested.

This study aims to analyze the impact of vocational training received by learning workers through the degree-linked work-study program on their learning outcomes. Specifically, we explore the causal relationship between various factors considered during university degree program admission and selection, and the average GPA (Grade Point Average) after admission. To achieve this, we conducted regression analysis and variance analysis using historical admission data and GPA records of 976 students from three undergraduate programs at a domestic K university that implements the degree-linked work-study model. Additionally, we included company information from publicly available databases that could potentially influence the academic performance of learning workers. Our analysis revealed significant causal relationships across various factors, including the classification of the high school attended, gender, family background, subject-specific grades in high school, duration of employment at the company, and age at the time of admission. Based on these findings, we anticipate that universities operating similar degree programs can enhance their selection procedures for learning workers. Furthermore, the results of this study can serve as foundational data for future policy recommendations related to degree-linked work-study programs.

Objectives. This study was conducted to evaluate the association between upper extremity musculoskeletal symptoms and Rapid Upper Limb Assessment(RULA) in vehicle assembly line workers. The goal of this study is to show the feasibility of RULA as a checklist for work related musculoskeletal symptoms (WMSDs) in Korean workers. Methods. The total number of 199 people from the department of assembly and 115 people from the department of Quality Control(QC) in automotive plant were subjects for this cross sectional study. A standard symptom questionnaire survey has been used for the individual characteristics, work history, musculosketal symptoms and non-occupational covariates. The data were obtained by applying one-on-one interview for the all subjects. RULA has been applied for ergonomic work posture analysis and the primary ergonomic risk sure was computed by RULA method. Association between upper extremity musculoskeletal symptoms and RULA were assessed by multiple logistic regression analysis. Results. A total of 314 workers was examined. The prevalence of musculoskeletal symptoms by NIOSH case definition was 62.4%. The distribution of musculoskeletal symptoms by the part of the body turned out to be following; back:41.4%, neck: 32.8%, shoulder: 26.4%, arm: 10.5% and hand:29.3%. The relationship of the individual RULA scores were statistically significant for the prevalence of musculoskeletal symptoms. As the result of the multiple logistic regressioin analysis, grand final score (OR=2.250 95% CI: 1.402-3.612) was associated with musculoskeletal symptoms in any part of the body.; upper arm score(OR=1.786 95% CI: 1.036-3.079) and posture score A(OR=1.634 95% CI: 1.016-2.626) in neck; muscel use score(OR=3.076 95% CI:1.782-5.310) and posture score A(OR=1.798 95% CI: 1.072-3.017) in shoulder; upper arm score(OR=1.715 95% CI: 1.083-2.715) and muscel use score(OR=2.057 95% CI:1.303-3.248) in neck & shoulder; muscle use score(OR=10.662 95% CI: 3.180-35.742) in arm; writst/wist score(OR=2.068 95% CI: 1.130-3.786) and muscle use score(OR=2.215 95% CI: 1.284-3.819) in hand & wrist.; muscle use score of trunk (OR=2.601 95% CI: 1.147-5.901) in back. Conclusions. Musculoskeletal symptoms of the extremities were strongly associated with individual RULA body score. These results show that RULA can be used as a useful assessment tool for the evaluation of musculoskeletal loading which is known to contribute to work-related musculoskeletal disorders. RULA also can be used as a screening tool or incorporated into a wider ergonomic assessment of epidemiological, physical, mental, environmental and organizational factors. As shown in this study, complement of the analysis system for the other risk factors and characterizing between the upper limb and back part will be needed for future work.

This study was performed to examine the annual experience rate of musculoskeletal symptom and its related factors in rural farmers. Six-hundred and sixty one rural farmers were investigated by questionnaire survey through interview from July 1 to July 31 in 2000. The results were as follows; The rural farmers who had experienced musculoskeletal symptom during recent 1 year was 82.7% in male, 92.1% in female. The annual experience rate of musculoskeletal symptom by part of the body in male were turned out as back; 42.3% leg and knee; 36.4%, shoulder; 21.4%, arm and hand; 12.7%, elbow; 7.7%, hip; 6.8% neck; 6.4%, ankle and foot; 6.4% in order. The annual experience rate of musculoskeletal symptom by part of the body in female were turned out as back; 59.4%, leg and knee; 48.5%, shoulder; 20.2%, arm and hand; 13.8%, hip; 10.7%, neck; 6.8%, ankle and foot; 6.3%, elbow; 5.0% in order. The annual experience rate of musculoskeletal symptom, back pain, and pain on leg and knee were significantly higher in female. In male, the experience rate of musculoskeletal symptom was different significantly according to educational level, family size, economic status, status of smoking, duration of farming, type of major agricultural affairs. By the multiple logistic regression analysis for experience of musculoskeletal symptom, family size and economic status were the significant variables. It was higher in male with no or one family living together and low economic status. In female, the experience rate of musculoskeletal symptom was different significantly according to body mass index, perceived health status, type of agricultural affairs. By the multiple logistic regression analysis for experience of musculoskeletal symptom, body mass index, perceived health status, and type of major agricultural affairs were the significant variables. It was higher as female farmer's body mass index was increasing and when female farmer's perceived health status was not healthier, and it was lower when female farmer did livestock farming as major agricultural affair. The experience rate of musculoskeletal symptom was higher in the busy season for farmers and treatment methods for musculoskeletal symptom were physical therapy, medication, herb medical treatment, etc. In conclusion, because most of farmers experience musculoskeletal symptom, continuous systematic study on musculoskeletal symptom of farmers and active effort to prevent and manage musculoskeletal symptom of farmers are necessary.

Purpose : Radiofrequency catheter ablation (RFCA) has become an effective therapeutic modality for treating pediatric tachyarrhythmias. Using conventional RFCA catheters, ablation of parahisian accessory pathways may be difficult and have high risk for heart block. We reviewed the efficacy and complications of the RFCA in children and adolescent with arrhythmias including parahisian accessory pathways. Methods : We studied 48 patients (aged 2 years to 20 years) who had undergone RFCA from August 2003 to March 2007. We reviewed clinical findings, electrophysiologic studies, RFCA data, complications, and follow-up results of the patients. Results : Mean age of the patients was 13.1 years. Numbers and types of arrhythmias (age, acute success rate) were as follows: 19 WPW syndrome including 5 parahisian accessory pathways ($13.7{\pm}4.6yr$, 18/19), 11 atrioventricular reentrant tachycardia with concealed bypass tract ($12.3{\pm}5.0yr$, 10/11), 13 atrioventricular nodal reentrant tachycardia ($12.6{\pm}4.4yr$, 13/13), 4 atrial flutter ($13.0{\pm}7.4yr$, 3/4), and 1 ventricular tachycardia (20 yr, 1/1). Associated cardiac structural lesion was not detected in 48 patients. The recurrence rate was 6.5%, and the final success rate was 93.8%. Conclusion : These results suggest that RFCA is a highly effective treatment method in children and adolescent with tachyarrhythmia.

Objectives: Suicide is one of the leading causes of death among young adults. We investigated whether anxiety level and sleep quality were related to suicide ideation among university students. Methods: Questionnaires were distributed to 1094 students at a local college. The scale for suicide Ideation, the Hospital Anxiety-Depression scale, the Pittsburgh Sleep Quality Index, and Morningness-eveningness questionnaires were used. Multiple linear regression analysis was conducted to examine the relationship between these variables and suicide ideation. Results: Among the 292 students who answered the suicide ideation questionnaire, 31 students had a high suicide ideation score and 261 patients had a low suicide ideation score. Demographic variables that showed significant differences between the two groups were gender, exercise, chronotype, sleep quality, depression and anxiety. The results of multiple linear regression analysis showed that suicidal ideation increased as the level of sleep quality decreased. There was no significant relationship between depression and suicidal ideation. Another multiple linear regression analysis was performed to evaluate the relationship between sleep quality sleep related factors. This suggested the quality of sleep decreased as weekend oversleep increased. Conclusion: The results of this study showed that when anxiety was higher and the quality of sleep was lower, the more suicide ideation increased. Therefore, improving sleep quality and reducing anxiety are important strategies for reducing suicidal ideation.

Purpose : Internal tibial torsion is prevalent in East Asian countries such as Korea and Japan, where sitting on the floor is common behavior. Internal tibial torsion or excessive lateral tibial torsion may cause esthetical, functional, or psychological problems and also may induce degenerative arthritis in older age. The purpose of this study is to measure the tibial torsion in children of the Jeju area. Methods : Tibial torsion was measured in 1,042 lower extremities of 521 children from one to 12 years of age. The values of transmalleolar angles were analyzed for each age group divided by 6 months. Quadratic and linear regression models were used to fit patterns of changes in mean values of transmalleolar angles. The age at seven, which provides the highest coefficient of determination for quadratic regression analysis, was used as a cut-off point to fit different statistical models. Results : The mean transmalleolar angle was $0.10{\pm}5.79^{\circ}$ in all children,$ 0.90{\pm}5.49^{\circ}$ in males, and $-0.80{\pm}5.97^{\circ}$ in females. The value was $4.25{\pm}4.04$ in 1 year of age, gradually decreased to the lowest level of $-1.98^{\circ}$ in four years and seven months of age, increased again with age until it reached $0.67{\pm}1.10^{\circ}$ at seven years of age, and stayed at that level thereafter. Conclusion : Internal tibial torsion in infancy is known to correct spontaneously in the normal developing process. But in this study, the mean transmalleolar angle in children of Jeju area annually decreased after one year of age; to the lowest angle at four years and seven months of age; increased again gradually to the age of seven; and persisted in that level, about $10^{\circ}$ less than western children, not correcting further thereafter. These findings suggest tibial torsion might be caused by lifestyle, especially sitting on feet. To prevent abnormalities of joints and gaits, early diagnosis of tibial torsion in childhood and posture correction or early treatment when needed, seems to be necessary.
