  • The aims of this study were to find out present situation of self-medication, and to explicate the factors affecting self-medication propensity. To explicate empirically the factors affecting self-medication propensity, a model containing five groups of determining factors such as attitudinal, behavioral, knowled해, and need of health care factors, and demographic factors were developed. Data were collected from 647 residents in Pusan and Kyungnam using the self-administered questionnaire. The major reslts obtained were as follows: First, self-medication was 32% of all utilization of pharmacy. The drugs used for self-medication most commonly were analgesics(16.2%), followed by antacids and stomachics(14.2%), dermatologic preparations(13.1%), tonics and drinks (12.6%). Second, the sources from which people obtained drug information at self-medication were label of the container(50.8%), pharmacist(32.4%), self-decision or lay person(16.8%). The experience of side effect was 10.6% of all self-medication and how people cope with was withdrawal(59.0%), consultation by pharmacist or doctor(35.9%). Third, the results of ANOVA showed a statistically significant relationship between self-medication propensity and 3 demograpic factors, such as sex(p<0.10), age(p<0.10) and job(p<0.05). Forth, the results of multiple regression analysis showed a statistically significant positive relationship betwee self-medication propensity and satisfaction of previous self-medication, knowledge of drug, drug dependency, the frequency of doctor visiting, confidence in drug advertisement, tendency toward self-treatment of the family, and job. And it showed negative relationship between self-medication propensity and confidence in the medical profession, and health behavior. The model explained 29.5% of the variance in self-medication(p<0.001).

  • Purpose: This study was aimed to find out the effect of core competency and teaching style on preceptor self-efficacy among preceptors. Methods: One hundred twelve nurses working at four university hospitals with previous preceptor experience participated in the survey. The data were analyzed by t-test, ANOVA, Pearson correlation coefficients and multiple regression. Results: The preceptors used 'judgment-initiative' teaching style most frequently, and reported the highest scores in the role model dimension of core competency. There were significant positive relations between age (r=.266, p=.005), clinical experience (r=.274, p=.004), preceptorship experience (r=.204, p=.032), core competency (r=.593, p<.001) and preceptor self- efficacy. But preceptor self-efficacy was not significantly different depending on the teaching style (F=0.72, p=.54). The most predictive factors of the preceptor self-efficacy were core competency and teaching style (judgment)(F=31.849, p<.001). The explained variance for preceptor self-efficacy was 35.9% in the model. Conclusion: The preceptor self-efficacy is essential for the preceptors' successful teaching experience and the clinical competency improvement of the entry level nurses. Management for an effective preceptor training program needs to focus on the improvement of core competency of preceptors, which will lead to strengthen their self-efficacy.

  • Purpose: The purpose of this study was to investigate the determinants of job satisfaction of hospital nurses. The focus was on work rewards. A causal model of job satisfaction of hospital nurses was constructed based on situational perspectives. Methods: The sample for this study consisted of 505 nurses from 2 general hospitals located in Seoul and Kyeonggi Province, Korea. Data were collected with self-administrated questionnaires and analyzed by hierarchical multiple regression. Results: All variables except workload were positively correlated with job satisfaction. It was found that three task reward variables(workload, meaning, and participation), two organizational reward variables(security and promotional chances) and one social reward variable(family support) had significant influence on nurses' job satisfaction. The explained variance for job satisfaction was 41.4%. The data further indicate that task rewards were the most significant determinants of nurse job satisfaction. Conclusion: Theses findings provide strong empirical evidence for importance of task, organizational and social reward variables in explaining job satisfaction of nurses. The model used for this study will be useful for predicting nurse job satisfaction.

  • Purpose: As the number of infertile couples has grown, many infertile women have experienced depression during the diagnosis and treatment of their infertility. This study aimed to identify the factors related to depression in infertile women who underwent reproductive treatments. Methods: The study subjects were 149 infertile women who underwent reproductive treatments. The data were collected by self-administered questionnaires from August 1 to December 24, 2018. The questionnaire consisted of questions about fatigue, health-promoting behavior, and depression. Analyses of the descriptive statistics, t-tests, one-way analysis of variance, correlation, and multiple regression were conducted using the SPSS 25.0 Windows program. Results: Thirty-six of the women in the study (24.2%) were in the probably depressed group and 113 (75.8%) were in the definitely depressed group and 100% of the subjects experienced symptoms of depression. Depression was positively correlated with fatigue and negatively correlated with health-promoting behavior. Multiple regression analysis revealed that fatigue and interpersonal relationships were factors significantly related to depression in the model (p<.001), with an explanatory power of 42.6%. Conclusion: The results confirmed that fatigue and interpersonal relationships, which is a subfactor of health-promoting behavior, were factors related to depression. To alleviate depression in infertile women, efforts should be made to identify and reduce psychological and physical fatigue. In addition, minimizing relational difficulties that they experience during an infertility diagnosis and treatment and strengthening positive interpersonal relationships can be positive strategies to alleviate depression.

  • Purpose: The purpose of this study was to examine the psychological distress related to quality of life (QoL) of patients with colorectal cancer receiving 5-fluorouracil (5-FU) chemotherapy at home with disposable Elastomeric infusion pumps. Methods: In this study, 179 colorectal outpatients were recruited between September 2019 and January 2021. National Cancer Center Psychological Symptom Inventory scores, general self-efficacy, and the EORTC QLQ-C30 scores were measured. Data were analyzed using Independent t-test, One-way ANOVA with Bonferroni post hoc analysis, and hierarchical multiple linear regression with the SPSS/WIN 26.0 programs. Results: The overall prevalence of psychological distress was 52.0% in colorectal patients. In multiple regression, psychological distress (β=-.20, p=.005), appetite loss (β=-.20, p=.001), chemotherapy cycles (β= .19, p=.002), fatigue (β=-.16, p=.035), physical functioning (β=-.16, p=.024), and emotional functioning (β=-.15, p=.025) were significant factors of QoL, and the final model explained 45.0% of the total variance of QoL. Conclusion: Supporting patients toward decreased psychological distress and increased physical and emotional functioning, especially in the first or second cycle of chemotherapy, could be used to improve their QoL. To consider the thresholds for clinical importance, it is necessary to increase the interpretation of psychological distress in clinical practice and further research.

  • This cross-sectional study was conducted to describe the changes of plasma cardiovascular disease(CVD) risk factors in Korea. Overnight fasting plasma levels of total cholesterol, high density lipoprotein(HDL)-cholesterol, triacylglycerol and glucose were analyzed. Blood pressure and anthropometric data were also measured. Health practice factors such as smoking status, alcohol consumption and frequency fo exercise were evaluated by a self-administered questionnaire. Questions regarding dietary habits and food preferences were also asked. Seventy eight percent of the subjects had more than one CVD risk factor. Plasma total cholesterol, triacylglycerol, and fasting blood glucose were significantly increased according to the subjects body mass index$(kg/m^2$, BMI), whereas HDL-cholesterol, low density lipoprotein(LDL)-cholesterol and blood pressure showed no significant differences with BMI. Current smokers had significantly high plasma total cholesterol, LDL-cholesterol and triacylglycerol levels. Alcohol consumption significantly increased plasma total cholesterol and fasting blood sugar, but regular exercise had no effects on the plasma CVD risk factors. Overeating and frequency of fast food consumption were positively correlated with the CVD risk score, whereas intake of grains, meats and vegetables were negatively correlated with that score. A stepwise multiple regression analysis was performed to examine the effects of specific dietary factors on plasma lipid levels. For plasma total cholesterol level, the frequency of fast food intake explained 8% of the variance, followed by habitual overeating, frequency of grain intake and high cholesterol food intake(Model $R^2$=22.4%). For plasma triacylglycerol level, preference of oily foods accounted for 7.5% of the variance, followed by eating breakfast, preference of fruit and frequency of grain intake(Model $R^2$=22.0%). The findings suggest that intervention programs to reduce the risk of CVD should focus on health practice through reducing BMI, smoking cessation and moderate or no alcohol drinking. Moreover, desirable dietary habits such as eating breakfast, not overeating and reduced intake of fast food may improve CVD risk.

  • Purpose: To investigate the subjective health and health-related quality of life (HRQoL) in Haenyo. Methods: Subjects were 100 elderly Haenyo in Jeju island who belonged to a fishing-village society. Main variables were activities of daily living (ADL), instrumental ADL (IADL), the HRQoL, subjective health, and depression. Subjective health and differences of HRQoL by variables were analyzed by t-test or ANOVA using IBM SPSS Statistics 23. Hierarchical multiple regression was executed to examine the effects of the major factors on the quality of life. Results: The mean age was 69.9 years, the mean period for diving career was 51.5 years, and work hours per month were 37.8. Comorbidity of diseases was 2.74, and the common health problems were osteoporosis and headache/dizziness. HRQoL was significantly different by age (F=4.52, p=.013), education (F=6.10, p=.003), muljil work years (F=3.93, p=.050), depression (t=-3.04, p=.030), subjective health state (F=30.62, p<.01), and degenerative arthritis (F=-2.38, p=.019). In the final model by hierarchical multiple regression, ADL/IADL (${\beta}=.41$, p<.001), depression (${\beta}=-.29$, p<.001), and subjective health (${\beta}=.43{\sim}.51$, p<.001) were significant and explained 63.5% of the total variance of HRQoL. Conclusion: Haenyo have specific health problems different from those of elderly women in general. ADL/IADL, depression and subjective health affected their HRQoL. It is clear that Haenyos' health problems need further study to improve their health.
