  • Purpose: The purpose of this study was to investigate the associations of mental health recovery to internalized stigma and meaning in life of community-dwelling people with mental disorder. Methods: Participants were 150 people with mental disorder who were enrolled at one of the community mental health institutions in D, S, and U cities, South Korea. Data analyses included a descriptive analysis, t-tests, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression using SPSS 25.0 software. Results: There were significant mean differences in mental health recovery according to education, religion, residential status, diagnosis, and day program use status of people with mental disorder living in the community. The significant predictors of mental health recovery included presence of meaning, stigma resistance, diagnosis (Major depressive disorder), and search for meaning. The regression model explained 58.7% of mental health recovery. Conclusion: Improving meaning in life and stigma resistance will increase the chances of mental health recovery among community- dwelling people with mental disorder.

  • Purpose: This study aims to identify factors influencing the health-related quality of life among women merchants at traditional markets. Methods: Participants in this cross-sectional descriptive study included 121 women merchants. Data were collected from May 01 to June 30, 2019 using the patient health questionnaire-9 (PHQ-9), psychosocial well-being index-short form (PWI-SF), subjective health status, and HRQoL. Selected data were analyzed using descriptive statistics, Pearson's correlation coefficient, and stepwise multiple regression by applying the SPSS/WIN program 22.0. Results: The HRQoL was significantly different by age (F=5.87, p=.001), education (F=2.98, p=.022), working period (F=4.70, p=.004), exercise (t=2.20, p=.030), chronic disease (t=-2.57, p=.011), BMI (F=5.04, p=.008), depression (F=4.70, p=.004), stress (F=7.82, p<.001), and subjective health status (F=7.91, p=.001). Factors influencing the HRQoL for women merchants included BMI (β=-.35, p<.001), subjective health status (β=.33, p<.001), and stress (β=-.18, p=.021). The explanation power of this regression model was 29.8% (F=5.51, p<.021). Conclusion: BMI, subjective health status, and stress affect the HRQoL of the subjects evaluated. Therefore, there is a need for health management programs that may decrease stress, control the BMI, and improve the subjective health status of women merchants at traditional markets.

  • Purpose : This study aimed to investigate the impact of clinical reasoning competence, positive psychological capital, and nursing work environment on nursing performance of intensive care unit (ICU) nurses in tertiary general hospitals. Methods : Data were collected from 169 ICU nurses in tertiary general hospitals in Busan, South Korea, from July 27 to August 15, 2023, using a self-report questionnaire. After excluding 12 questionnaires with insufficient responses, 157 responses were analyzed. Descriptive statistics, independent t-test, one-way ANOVA, Pearson's correlation coefficient, and stepwise multiple regression analysis were employed. Results : Factors influencing nursing performance included clinical reasoning competence (β=.51, p <.001), hope as a subfactor of positive psychological capital (β=.31, p <.001), and the nursing foundations for quality of care in the nursing work environment (β=.21, p <.001). The explanatory power of the regression model was 62% (F=87.41, p <.001). Conclusion : The study underscores the importance of improving clinical reasoning competence among ICU nurses to enhance nursing performance and foster a hopeful attitude through reflective practices and personal growth. Organizational interventions, such as educational and psychological support programs, along with creating a supportive nursing environment, are crucial for improving nursing performance among intensive care unit nurses.

  • The purpose of this study was to produce the regression equation from non-exercise $VO_{2max}$ of healthy young adults and to develop a maximal oxygen consumption ($VO_{2max}$) regression model. This model was based on heart rate non-exercise predictor variables (rest heart rate, maximal heart rate/rest heart rate), as an extra addition to the general regression which can reflect an individual's inherent or acquired cardiorespiratory fitness. The subjects were 101 healthy young adults aged 19 to 35 years. Exercise testing was measured by using a Balke protocol for treadmill and indirect calorimetry. The prediction equation was analyzed by using stepwise multiple regression procedures. The mean of $VO_{2max}$ was $39.02{\pm}6.72\;m{\ell}/kg/min$ (mean${\pm}$SD). The greatest variable correlated to $VO_{2max}$ was %fat. The predictor variable used in the non-exercise $VO_{2max}$ included %fat, gender, habitual physical activity and $HR_{max}/HR_{rest}$. The non-exercise $VO_{2max}$ estimation was as follows: $VO_{2max}$($m{\ell}/kg/min$)=55.58-.41(%fat)+.59(physical activity rating)-2.69($HR_{max}/HR_{rest}$)-5.36 (male=0, female=1); (R=.85, SEE=3.64, R2=.72: including heart rate variable); $VO_{2max}$($m{\ell}/kg/min$)=48.47-.41(%fat)+.45(physical activity rating)-5.12 (male=0, female=1); (R=.84, SEE=3.74, R2=.70: with the exception of heart rate variable). As an added heart rate variable, there was only a 2% coefficient of determination improved. Therefore, these results demonstrated that heart rate variable correlation with a non-exercise regression model was very low. In conclusion, for healthy young korean adults, those variables that can affect non-exercise $VO_{2max}$ estimation turned out to be only % fat, gender, and physical activity. We suggest that further research of predictor variables for non-exercise $VO_{2max}$ is necessary for different patient groups who cannot perform maximal exercise or submaximal exercise.

  • It has been noted that a genetic alteration of cells influenced by unhealthy lifestyle In addition to a series of other carcinogens increases various neoplasmic diseases. Therefore the importance of lifestyle that minimizes such impact on health should be emphasized. Since stomach cancer, the most common neoplasmic disease in Korea, is re-lated to the Korean lifestyle and as there's a possibility of its recurrence, people with stomach cancer need to lead a healthy lifestyle. The purpose of this study is to provide a basis for nursing intervention strategies to promote health promoting behaviors that are constructive to a healthy lifestyle. A multivariate model was constructed based on the fender's health promotion model and Booker's health belief model by including influential factors such as hope. The sample was composed of 164 patients with stomach cancer who visited outpatient clinics of a university hospital in Seoul. The following instruments were used in the study after some adaptation : Wallston and others' multidimensional health locus of control scale Laffrey's health conception scale, Lawston and others' health self- rating scale, Walker and others' health promotion lifestyle profile and Rogenberg's self esteem scale. In addition Moon's health belief scale was used with some modification. For self efficacy, the present author constructed a self-efficacy scale based on previous research. The above mentioned instruments were tested in a pilot study with 24 patients with stomach cancer. The reliabilities of instruments were tested with Cronbach's alpha(0.574∼0.949). Data were analyzed using a SAS program (or Pearson correlation coefficients, descriptive correlational statistics and stepwise multiple regression. The results are as follows : 1. The scores on the health promoting behavior scale ranged from 55 to 145 with a mean of 107.91 (S. D : 16.50). The mean scores(range 1-4) on the different dimensions were nutrition 3.14, exercise 2.48, stress management 2.69, health responsibility 2.65, interpersonal relationship 2.878E self actualization 2.85. 2. There were significant correlations among all the predictive variables & the health promoting behavior (r=.20-.55, p〈.01) 3. Stepwise multiple regression analysis showed that : 1) Hope was the main predictor and accounted for 29.8% of the total variance. 2) Self efficacy, perceived barriers & self esteem accounted for an additional 14.6% of the total variance. 3) Hope, self efficacy, perceived barriers & self esteem altogether accounted for 44.3% of the total variance. In conclusion, hope, self efficacy, perceived barriers & self esteem were identified as important variables that contributed to promote health promoting behavior.

  • The purpose of this study was to identify the factors influencing health promoting behavior of college students to develop health promoting interventions of young adults. The subjects of this study were 176 women college students, living in a small city in Korea. The data were collected by interviews and a self-report questionnaire, during the period from September, 1999 to December, 1999. The instruments for this study were the PRQ-II by Weinert(1988), the scale of Locus of Control by Wallstone et al.(1978), the scale of self efficacy by Sherer & Maddux(1982), 10 points visual analogue scale for perceived health status and the importance of health, the health promoting behavior scale by Walker et al.(1987), and the scales developed by the authors for the perceived benefits of health promoting behavior, and perceived barriers to health promoting behavior. Cronbach 's alpha of these scales were .68 ~.89. The data were analyzed using descriptive statistics, Pearson's correlation coefficients, and stepwise multiple regression. The results of this study were as follows: 1. Among cognitive perceptual factors of the Health Promotion Model by Pender(1987), the scores of the importance of health, the perceived internal control of health, self efficacy, the perceived health status, and the perceived benefits had a significantly positive correlation with the scores of the health promoting behavior of college students. In addition, the scores of the perceived barriers had a significantly negative correlation with the scores of the health promoting behavior of college students. 2. Among modifying factors of the Health Promotion Model by Pender(1987), the extent of religious activities of college students and the scores of social support had a significantly positive correlation with the scores of health promoting behavior of college students. 3. Stepwise multiple regression analysis revealed that the most powerful predictor of health promoting behavior was self-efficacy. A combination of self-efficacy, the perceived benefits, the perceived barriers, the perceived health status, and the importance of health accounted for 45.1% of the variance in health promoting behavior in college students From the results of this study, we concluded that the Health Promotion Model by Pender can be used to explain health promoting behavior of college students. In addition, we suggested that the results of this study be considered in developing health promoting programs of young adults.

  • As an attempt to characterize the English test section of CSAT (College Scholastic Ability Test) and to get some suggestions, this study raised the research questions, as 'What are the main factors that affect students' English test scores in CSAT, and how big influences do they have?' It has been hypothesized that among main factors are the L1 competence, represented by the Korean test scores in CSAT, background knowledge or intelligence, represented by the "total" scores in CSAT, and the two types of L2 knowledge (vocabulary and grammar on one hand and prosody m the other hand), measured by the test devised specially for this study. The individual effect of the L2 vocabulary and grammar (one kind of L2 knowledge) was 70%, that of background knowledge or intelligence 61%, that of the L1 competence 50%, and that of the L2 prosody knowledge (the other kind of L2 knowledge) 32%. According to the stepwise regression, the whole effect of these four factors was 74%. The findings suggest that first, although CSAT is based on the top-down model of comprehension, the bottom-up model of learning should be more emphasized in our English class. Also, since background knowledge or intelligence is the second most influential factor, the top-down model of learning that helps students learn to understand by activating their various schemata must also be very effective.

  • The purpose of the study was to find the sociopsychological factors predicting the intention of compliance with the dietary regimen in diabetes with a questionnaire. Data were collected from 282 adult noninsulin-dependent diabetics in Seoul, Kyoggida, and Kyongsangbukdo in Korea. Stepwise multiple regression analysis was conducted with predictor variables from theories of the Health Belief Model, Social Cognitive Model, The Theory of Reasoned Action , and Social Support. The behavioral intention of compliance with the prescribed diet was the independent variable. Subjects norm self-efficacy knowledge about diet therapy, outcome expectation, relationship with medical team, threat of deterioration of disease, and social support were the independent variables, The mean score of behavior intention was high ie 35.3 out to 42. Subjective norm and self-efficacy were the significant variables to predict the intention of dietary compliance. These variables comprised 39% of the common variance. To increase dietary compliance by influence of the referents and improve self-efficacy significant referents must be included and concrete and practical methods to follow the dietary regimen must be provided in nutrition education.

  • This paper describes the differences of the information system's success factors to improve the end-user's performance according to the job characteristics. A modified model of DeLone and McLean's IS success model is proposed with the two added variables of the top management concern and the IS department support. The model is validated using data collected from a field study of 3872 users on 3 Korean companies. ANOVA, correlation analysis, and stepwise regression are used to test research hypotheses. The results of the study indicate the following implications. First the top management concern and the IS department support have the significant relation with the system usage and the user satisfaction. Second, the system quality has an influence on the user satisfaction more than on the system usage. And the information quality has an influence on the system usage more than on the user satisfaction. Third, the system usage has more relations to the user's performance in the logistics function and R&D function. The user satisfaction has more relations to the user's performance in the sales and the A/S function. Therefore information system strategy to increase the user's performance must be differentiated according to job characteristics.
