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 is to investigate correction-level associated with the social support perceived by juvenile delinquents. To accomplish these purposes, this study used sample of 546 juvenile delinquents who are in the process of the beginning stage in the police and prosecution. Social support and correction were assessed with an instrument designed for this study. Juvenile delinquents completed instruments assessing the following variables: (1) perceived social support scale, specially social support types(esteem support, emotional support, informational support) and social support providers (parents, relatives, friends, teachers, community) (2) correction scale, specially social stigma, social deprivation, self reflection, legal consciousness, self concept. The resulting scale of the instrument had good internal reliability(Cronbach's alpha=. ) and was scored so that high scores indicated a willingness to access. To examine this purpose, One way ANOVA, multiple regression analysis were conducted. And the results are as follows: The relationship ratings of the correction factors were positively associated with their rating of the type of social support. Informational support was positively associated with self reflection and esteem support was positively associated with self concept, legal consciousness, self reflection and emotional support were positively associated with esteem. The type of support according to support providers was significant, explaining 25% of the variance in self concept scores. The significant predictor was esteem support from friends and emotional support from a community. The type of support according to support providers was significant, explaining 20% of the variance in legal consciousness scores. The significant predictor was informational support from teachers and esteem support from a community. The type of support according to support providers was significant, explaining 21% of the variance in self reflection scores. The significant predictor was esteem support and emotional one from relatives.

Purpose: The purpose of this study was to investigate the factors that influence ego-resilience among adolescents who have experienced abuse by parents in South Korea. Methods: This correlational study used the 4th year cross-sectional data of the seventh-grade middle school students who participated in the Korean Children and Youth Panel Survey (KCYPS) in fourth grade. Data analysis was performed by using SPSS/WIN 23.0 program, which included descriptive statistics, Pearson's correlations coefficient, and hierarchical regression. Results: The results of the hierarchical regression of model 5 revealed that the quality of peer relations played the most significant role in predicting ego-resilience of abused adolescents, followed by self-identity. Also, self-esteem, the quality of teacher-student relationships, excessive expectations from parents, and community awareness had a significant impact on the variance of self-resilience in abused adolescents. This regression model explained 42% of the variance. Conclusion: This study showed that ego-resilience, an asset and resource to help adolescents overcome adverse effects of abuse, was influenced by social environment as well as individual factors. In addition, social support from peers and teachers had greater influence on ego-resilience than support from family members. Thus, the factors identified in this study need to be considered in programs designed to improve ego-resilience as well as in policies for abused adolescents.

Purpose: The purpose of this study is to identify relationships between acculturation, social network, and health-related quality of life (HRQOL) among Korean-Chinese immigrants. Methods: A cross-sectional descriptive study was conducted with 147 Korean-Chinese immigrants who were residing more than 1 year in Korea. Physical and mental dimensions of HRQOL were assessed by Short Form-12 Health Survey that consisted of a physical component summary (PCS) and a mental component summary (MCS). Data were analyzed with Pearson's correlation and multiple regression. Results: The mean PCS score was $41.14{\pm}10.72$ and the mean MCS score was $49.09{\pm}11.31$ (possible range 10-70). Depression (${\beta}$=-6.43) and Social network frequency (${\beta}$=2.44) explained 28.4% of the variance in PCS while depression (${\beta}$=-11.54) and visiting clinic/hospital (${\beta}$=-4.00) explained 34.3% of the variance in MCS. Acculturation was not significantly associated with HRQOL. Conclusion: This study confirmed that the social network frequency influences HRQOL among Korean-Chinese Immigrants. The findings suggest that social network analysis should be considered in the process of developing health intervention strategies for Korean-Chinese immigrants.

Purpose: The aim of this study was to identify the factors explaining protective behaviors against radiation exposure in perioperative nurses based on the theory of planned behavior. Methods: This was a cross-sectional study. A total of 229 perioperative nurses participated between October 3 and October 20, 2021. Data were analyzed using SPSS/WIN 23.0 and AMOS 23.0 software. The three exogenous variables (attitude toward radiation protective behaviors, subjective norm, and perceived behavioral control) and two endogenous variables (radiation protective intention and radiation protective behaviors) were surveyed. Results: The hypothetical model fit the data (χ²/df = 1.18, SRMR = .02, TLI = .98, CFI = .99, RMSEA = .03). Radiation protective intention (β = .24, p = .001) and attitude toward radiation protective behaviors (β = .32, p = .002) had direct effects on radiation protective behaviors. Subjective norm (β = .43, p = .002) and perceived behavior control (β = .24, p = .003) had direct effects on radiation protective intention, which explained 38.0% of the variance. Subjective norm (β = .10, p = .001) and perceived behavior control (β = .06, p = .002) had indirect effects via radiation protective intention on radiation protective behaviors. Attitude toward radiation protective behaviors, subjective norm, and perceived behavioral control were the significant factors explaining 49.0% of the variance in radiation protective behaviors. Conclusion: This study shows that the theory of planned behavior can be used to effectively predict radiation protective behaviors in perioperative nurses. Radiation safety guidelines or education programs to enhance perioperative nurses' protective behaviors should focus on radiation protective intention, attitude toward radiation protective behaviors, subjective norm, and perceived behavioral control.

Much of northern Asia is lacking in high-resolution palaeoclimatic data coverage. This vast region thus represents a sizeable gap in data sets used to reconstruct hemispheric-scale temperature trends for the past millennium. To improve coverage, we present a regional-scale composite of four tree-ring width records of Siberian pine and Siberian larch from temperature-sensitive alpine timber-line sites in Mongolia. The chronologies load closely in principal components analysis (PCA) with the first eigenvector accounting for over 53% of the variance from ad 1450 to 1998. The 20-year interval from 1974 to 1993 is the highest such growth period in this composite record, and 17 of the 20 highest growth years have occurred since 1946. Thus these trees, unlike those recently described at some northern sites, do not appear to have lost their temperature sensitivity, and suggest that recent decades have been some of the warmest in the past 500 years for this region. There are, however, comparable periods of inferred, local warmth for individual sites, e.g., in 1520-1580 and 1760-1790. The percent common variance between chronologies has increased through time and is highest (66.1%) in the present century. Although there are obvious differences among the individual chronologies, this result suggests a coherent signal which we consider to be related to temperature. The PCA scores show trends which strongly resemble those seen in recent temperature reconstructions for the Northern Hemisphere, very few of which included representation from Eurasia east of the Ural Mountains. The Mongolia series therefore provides independent corroboration for these reconstructions and their indications of unusual wanning during the twentieth century.

Purpose: The purpose of this study was to examine the relationships between treatment belief, personal control, depressive mood, and health-related quality of life in patients with hemodialysis based on self-regulation theory. Methods: Data were collected from 220 patients at 27 local hemodialysis clinics in Seoul during 2013 and 2014. The Revised Illness Perception Questionnaire, the Hospital Anxiety and Depression Scale, and Medical Outcomes Study Short Form-12 were used to measure outcome variables. Data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson correlation, and multiple regression using the 'enter' method. Results: Treatment belief and personal control scored 3.58 and 3.54 out of 5 points respectively, on average. Treatment belief and personal control of kidney disease were negatively correlated with depressive mood and positively correlated with health-related quality of life. According to the regression analysis, treatment belief, monthly income, and personal control were discovered to account for 21.8% of the variance in depressive mood, where as depressive mood, monthly income, treatment belief, and age were found out to account for 40.6% of the variance in health-related quality of life. Conclusion: Our study demonstrated significant positive relationships between treatment belief and illness outcome in hemodialysis patients. Interventions aimed to provide the necessary information and trust to maximize the effectiveness of treatment need be developed to improve patients outcomes.

Purpose: This study was conducted to identify influencing factors on the performance of healthcare-associated infection control and microbiological hand contamination among caregivers at a tertiary hospital. Methods: The participants of this study were 59 caregivers woring at a tertiary hospital. Data were collected from July 1 to 30, 2018. Data were analyzed using descriptive statistics, t-test, ANOVA, Scheffé test, Pearson's correlation coefficients and stepwise multiple regression by SPSS 23.0 Win program. Results: Multiple regression analysis revealed that factors influencing performance of healthcare-associated infection control were awareness (β=.63, p<.001) and the experience of infection-related education (β=-3.40, p=.042). Regression equations describing the performance of healthcare-related infection control were found to be appropriate (F=27.29, p<.001) and accounted for 68% of variance. Factors affecting the degree of microbiological hand contamination were work experience (β=-0.28, p=.026) and healthcare-related infection performance (β=-0.28, p=.029). A regression equation describing the microbiological hand contamination was appropriate (F=6.10, p=.004) and accounted for 42% of variance. Conclusion: The findings of this study suggest that it is necessary to increase performance of healthcare-associated infection control by caregivers. Also, educations for preventing healthcare-associated infection and guidelines for increasing compliance with healthcare-associated infection control are recommended to improve performance of healthcare-associated infection control.
