  • This study was conducted to identify the effects of ego resilience, interpersonal relationships, and cognitive emotion regulation strategies on adaptation to college life by nursing students and provide data to increase adaptation based on the results. This research was based on 304 nursing students in B and Y city. Data were collected from May 8 to May 13, 2017 and analyzed by ANOVA, Pearson's correlation coefficient, and multiple regression using SPSS/WIN 22.0. The average college life adaptation value was $3.21{\pm}0.53$. There were positive correlations between college life adaptation and ego resilience (r=0.443, p<0.001), interpersonal relationships (r=0.400, p<0.001) and cognitive emotion regulation strategies (r=0.465, p<0.001). Regression analysis revealed that 46.2% of the variance in college life adaptation by nursing students could be explained by grade, major satisfaction, ego resilience, and cognitive emotion regulation strategies. Additional studies to determine the various factors affecting adaptation of nursing students to college life and to increase college life adaptation should be conducted.

  • This study has two objectives. First, this study examines subjective well-being among elders that operationalize life satisfaction and aging anxiety, guided by life-course perspective. Second, it examines the relationship between subjective well-being and age-friendly environment factor structure among age-cohort groups. This study employs the stratified sampling method from 4,000 Seoul citizens. Main findings from the multivariate regression analyses include: (1) as age increases, aging anxiety levels appeared to be higher, while decreasing the life satisfaction. (2) a substantially larger variance of life satisfaction and aging anxiety was accounted for by demographic variables and age-friendly environments across age-cohort groups. (3) the influence of age-friendly environment factors such as neighborhood problems, accessibility to social activities, social services and parks on subjective well-being was different across age-cohort groups. This study discusses the policy and practical implications of the results.

  • This study examined whether Dybowski's brown frogs(Rana dybowskii) in noisy highway roadsides had different mating calls from those in natural sites. We selected four study sites: two rice paddy sites in Youngdong Highway roadside and two nearby natural counterparts. Frog calls were recorded between 18:30 and 20:00 on February 24, February 27, and March 14, 2014. Frog calls in the natural sites had fundamental frequency approximately at 700 Hz with two to four apparent harmonics, while frog calls in the highway sites had higher fundamental frequency with up to seven apparent harmonics. Analysis of variance (ANOVA) shows that a roadside site that are directly exposed to highway noise had statistically higher frog calling frequency than other study sites. However, the higher calling frequency was not found in another roadside site that differed in elevation from the highway and was buffered by forests. These results indicate that male frogs in a noisy highway roadside called females with a higher pitch and more apparent harmonics to avoid being masked by highway noise. These results also suggest that there is a threshold noise level that interrupts frog's mating behavior and it is needed to maintain highway roadside noise to this threshold level.

  • Liquid Injection Nozzle(LIN) tube and Calandria tube(CT) in pressurized Heavy Water Reactor (PHWR) are .ross-aligned horizontally. These neighboring tubes can contact each other due to the sag of the calandria tube resulting from the irradiation creep and thermal creep, and fuel load, etc. In order to judge the contact which might be the safety concern, the remote field eddy current (RFEC) technology is applied for the gap measurement in this paper. LIN can be detected by inserting the RFEC probe into pressure tube (PT) at the crossing point directly. To obtain the optimal conditions of the RFEC inspection, the sensitivity, penetration and noise signals are considered simultaneously. The optimal frequency and coil spacing are 1kHz and 200mm respectively. Possible noises during LIN signal acquisition are caused by lift-off, PT thickness variation, and gap variation between PT and CT. The simulated noise signals were investigated by the Volume Integral Method(VIM). Signal analysis on the voltage plane describes the amplitude and shape of LIN and possible defects at several frequencies. All the RFEC measurements in the laboratory were done in variance with the CT/LIN gap and showed the relationship between the LIN gap and the signal parameters by analyzing the voltage plane signals.

  • Purpose: The purpose of this study was to identify the relationship of occupational stress, self esteem and mental health in nurses. Methods: The data were collected using questionnaire from the sample of 457 nurses selected by convenient sampling. The data were collected from July 4 to 29, 2011. The collected data was analyzed by the descriptive statistics, t-test, ANOVA, Scheffe, Pearson correlation coefficient and stepwise multiple regression(SPSS 18.0). Results: Mental health differed according to marital status, educational level, working unit and shift work. Mental health had a significant positive correlation with occupational stress and a significant negative correlation with self esteem. Stepwise multiple regression analysis showed insufficient occupational control, work overload, inappropriate treats and reward, interpersonal relation in occupational stress, self esteem, shift work(3 shift) explained 42.2% of the total variance in mental health. Conclusion: The findings indicate that occupational stress and self esteem have an influence on mental health. We need to develop and provide intervention programs to prevent and manage nurse's mental health problems.

  • This study was undertaken to investigate the factors that influence post-traumatic growth in patients with breast cancer. The study subjects were 100 outpatients with breast cancer who visited the outpatient clinic of a university hospital. The instruments used for this study were Korean Post-traumatic Inventory (K-PTGI), Modified Medical Outcomes Study Social Support Survey (mMOS-SS), Self-Efficacy Scale for Self-Management of Breast Cancer (SESSM-B) and Cancer Coping Questionnaire (CCQ). The data were analyzed by t-test, ANOVA, Pearson-correlation coefficient, and stepwise multiple regression using SPSS/WIN 21.0. The mean score of post-traumatic growth was $3.4{\pm}0.9$ out of 5. Post traumatic growth had statistically significant correlation with social support, breast cancer self-management self-efficacy, and coping behavior. In stepwise multiple regression analysis, post-traumatic growth was significantly influenced by therapeutic compliance related self-efficacy and positive reframing coping behavior and it was account for 29% of the total variance. These results suggest that these influencing factors should be considered in developing the nursing intervention to improve the post-traumatic growth in patient with breast cancer.

  • This study is a descriptive study designed to identify the relationships among positive psychological capital, physical health status, depression, interpersonal relationship and learning flow. The subjects were 181 nursing students and the data collection was from May 8 to June 20, 2019. Data analysis methods were descriptive statistics, t-tests, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression, using the SPSS 22.0 program. Positive psychological capital showed statistical differences according to age, grade, motive for major choice, major satisfaction and subjective health status. Positive psychological capital was correlated with depression(r=-.454, p<.001), interpersonal relationship(r=.611, p<.001) and learning flow(r=.452, p<.001). The factors affecting learning flow were positive psychological capital(β=.414, p<.001), major satisfaction(β=.177, p=.014), and grade(β=-.150, p=.026), which explained 24.4% of the variance. Therefore, it is necessary to develop and apply educational programs that can promote positive psychological capital in nursing students.

  • This study aimed to assess the prevalence of weight control behaviors and their association with food and nutrient intake among Korean adults. Study subjects were 7,340 Koreans aged 20 years and older in the 1998 Korean Health and Nutrient Survey. Cross-sectional data were collected on weight control behavior and diet using structured questionnaire by interview. Analysis of variance following after Duncan's multiple range test was used to test the differences in food and nutrient intake among three different weight control behavior groups(weight reducing attempt, weight gaining attempt, none). Current weight control behaviors were reported by 32% of the study subjects. There were significant differences in weight control behaviors between male and female subjects; weight reducing practices were 7 times greater than weight gaining practices among female subjects while it was only 1.5 times among male subjects. Weight control behaviors were not consistently associated with food and nutrient intake among male and female subjects. Moreover, greater food and nutrient intake were observed among those who trying to reducing weight than those who did not try. Therefore, it Is necessary to educate the Korean adults that balanced food and nutrient intake with sustaind weight control effort is the ideal way to achieve healthy weight.

  • This paper deals with the problem of estimating the log-transformed linear regression model to fit actual battle data from the Ardennes Campaign of World War II into the Lanchester model. The problem of determining a global solution for parameters and multicollinearity problems are identified and modified by examining the results of previous studies on data. The least squares method requires attention because a local solution can be found rather than a global solution if considering a specific constraint or a limited candidate group. The method of exploring this multicollinearity problem can be confirmed by a statistic known as a variance inflation factor. Therefore, the Lanchester model is simplified to avoid these problems, and the combat power attrition rate model was proposed which is statistically significant and easy to explain. When fitting the model, the dependence problem between the data has occurred due to autocorrelation. Matters that might be underestimated or overestimated were resolved by the Cochrane-Orcutt method as well as guaranteeing independence and normality.

  • Purpose: This study aims to identify factors that influence middle-aged men's attitude towards death. Methods: The study enrolled 204 middle-aged (range=40~59 years) male residents of Daegu in Korea. Using a structured questionnaire, data were collected in October 4~30, 2010. For data analysis, we used descriptive statistics, t-test, one-way ANOVA, Scheff$\grave{e}$'s test, Pearson correlation coefficient, and stepwise multiple regression with SPSS WIN 14.0. Results: Participants' attitude towards death significantly differed according to educational level, religion, volunteer activities, and perceived health status. Moreover, their attitude towards death was negatively correlated with life stress and depression and positively correlated with self-esteem, life satisfaction, and coping behavior. The factors influencing the attitude towards death were life satisfaction, daily stress, religion, and depression, which explained approximately 25.7% of the total variance. Conclusion: Middle-aged men perform a crucial role in our society, and their attitude toward death affects how they cope with a situational crisis such as a terminal cancer or withdrawal of life sustaining treatment. Therefore, it is necessary to develop and implement a support program for middle-aged men, which offers them with various strategies to better manage their daily stress and improve their life satisfaction and coping skills.
