This study investigated the role of organizational communication, culture and trust as a moderator of the organizational performance(the growth of production and quality improvement) and job satisfaction. Using data collected from 248 workers at 128 establishments in Changwon industrial complex, morderated regression analyses explored the proposed model. As a result, communication activity and organizational trust was found negatively to moderate the relationship between job satisfaction and quality improvement/the growth of production. And organizational culture was found positively to moderate the relationship between satisfaction and quality improvement. Implications of these findings were discussed.

Purpose: The purpose of this study was to identify the factors influencing self-identity and menopausal symptoms their influence on level of depression in middle-aged woman. Methods: Participants were 135 middle-aged women who were living in city B, were 45-60 years old, informed of study purpose, and agreed to participate. Data were collected from December, 2012 to January, 2013 using scales measuring depression, self-identity, and menopausal symptoms. Data were analyzed using t-test, ANOVA, Scheff$\acute{e}$ test, Pearson Correlation Coefficients, and Multiple Stepwise Regression. Results: Level of depression was low, self-identity was slightly high, and menopausal symptoms were relatively low in these middle-aged women. There were significant differences in depression by perceived health status and perceived economic status. Depression had a moderate negative correlation with self-identity (r=-.49, p<.001) and a moderate positive correlation with menopausal symptoms (r=.57, p<.001). Menopausal psychological symptoms were the factor most affecting depression and explained 37% of the variance in depression. A total of 51% of variance in depression was explained by menopausal symptoms (psychological and physical), self-identity, and perceived economic status. Conclusion: Thus, an effort to improve self-identity, especially a plan to attenuate menopausal psychological symptoms is needed to reduce depression.

Objective : The purpose of this study was to investigate the effectiveness of the mental health improvement program in Korean firefighters. Methods : A total of 502 firefighters working at Daegu, Ulsan and Gumi participated in the mental health improvement program for an 8-week period. The program included evaluation and counseling as well as psychoeducation for mental health awareness. Subjects were divided to two groups including the PTSD high risk group and PTSD non-high risk group. Results : The program resulted in a significant decrease in mean scores of depression and insomnia for all firefighters. PTSD high risk group showed a significantly higher level of depression, anxiety, and insomnia. Multiple logistic regression analysis with PTSD high risk group as a dependent variable indicated that moderate depression was a high-risk factor for PTSD in firefighters, as compared to no depression ; in addition, subthreshold and moderate insomnia was another risk factor. Conclusion : The evaluation and management of psychopathologies including depression and insomnia associated with traumatic events can be helpful to improve the mental health of firefighters.

Background/Aims: The aim of this study was to assess the association between the number of existing permanent teeth and chronic kidney disease (CKD) in a representative sample of the elderly Korean population. Methods: A total of 2,519 subjects who participated in the Korean National Health and Nutrition Examination Survey were cross-sectionally examined. The number of existing permanent teeth was evaluated by clinical oral examination. CKD was defined based on definition and classification by Kidney Disease: Improving Global Outcomes (KDIGO) 2012 guidelines. Multivariable logistic regression analyses were performed controlling for age, gender, income, education, tooth-brushing frequency, periodontitis, state of dentition, smoking, alcohol consumption, hypertension, obesity, diabetes mellitus, and hypercholesterolemia. Subgroup analyses by age and gender were also performed. Results: The number of teeth was significantly associated with CKD after controlling for all potential confounders (adjusted odds ratio [AOR], 1.67; 95% confidence interval [CI], 1.04 to 2.70 for lower number of teeth; AOR, 1.59; 95% CI, 1.14 to 2.23 for moderate number of teeth). In the subgroup analyses, the association was highlighted in females aged 75 years over (AOR, 2.55; 95% CI, 1.05 to 6.20 for lower number of teeth; AOR, 1.95; 95% CI, 1.01 to 3.80 for moderate number of teeth). Conclusions: Our findings suggest that the number of existing permanent teeth may be associated with CKD among Korean elderly.

Purpose: This study aimed to identify factors associated with diabetes management self-efficacy in pregnant women with gestational diabetes mellitus (GDM) in Korea. Methods: A total of 173 pregnant women with GDM in Korea were recruited by posting announcements at two Korean online communities focusing on pregnancy and GDM. Participants completed a structured online survey from July to September 2018. Thirteen inappropriate responses were excluded and a total of 160 questionnaires were used in the final analysis. Descriptive statistics were calculated and multiple regression with the enter method was done to identify the associations of depressive mood, anxiety, emotional intelligence, and sleep quality with diabetes management self-efficacy. Results: Respondents reported a moderately depressive mood (mean, 10.36), low to moderate anxiety (mean, 41.65), above-average emotional intelligence (mean, 78.04), moderate sleep quality (mean, 42.01), and above-average diabetes management self-efficacy (mean, 52.29). The major factor associated with diabetes management self-efficacy of pregnant women with GDM was emotional intelligence (β=.51, p<.001). Other factors, in descending order of influence, were sleep quality (β=.22, p<.001) and exercise (β=.18, p=.004). Taken together, the aforementioned factors explained 34.6% (F=39.53, p<.001) of the total variance. Conclusion: The results of this study suggest that to improve the diabetes management self-efficacy of pregnant women with GDM, it is necessary to develop an education program that can also enhance emotional intelligence, sleep quality, and exercise.

Purpose: This study aimed to investigate the association between obesity and high-sensitivity C-reactive protein (hs-CRP) levels in Korean adults without cardiovascular disease (CVD). Methods: The subjects were 3,634 adults, and data were extracted from the seventh Korea National Health and Nutrition Examination Survey (KNHANES VII-3). A complex sampling design analysis was applied to reflect the stratified and clustered weights. The data were analyzed using the complex sample Rao-Scott chi-square test and multiple logistic regression analysis (in SPSS for Windows version 26.0). Obesity, according to body mass index (BMI), was defined as obesity (BMI = 25-29.9 kg/m²), high obesity (BMI = 30-34.9 kg/m²), and super-high obesity (BMI ≥ 35 kg/m²), and abdominal obesity (AO) was defined as a waist circumference (WC) ≥ 90 cm in males and WC ≥ 85 cm in females. Results: The odds ratios for moderate CVD risk (hs-CRP; 1-3 mg/dL) were 2.21, 4.16, and 7.13 in the obesity, high obesity, and super-high obesity groups, respectively, compared to the normal BMI group. The odds ratio for moderate CVD risk was 2.18 in males with AO and 1.88 in females with AO. The odds ratios for high CVD risk (hs-CRP > 3 mg/L) were 4.40 and 17.55 in the high obesity and super-high obesity groups, respectively, compared to the normal BMI group. Conclusion: This study provides evidence that early detection and prevention programs for CVD should include obesity-related interventions aiming to modulate hs-CRP.

Objective: The objective of this study was to estimate genetic parameters of milk, fat, and protein yields within and across lactations in Tunisian Holsteins using a random regression test-day (TD) model. Methods: A random regression multiple trait multiple lactation TD model was used to estimate genetic parameters in the Tunisian dairy cattle population. Data were TD yields of milk, fat, and protein from the first three lactations. Random regressions were modeled with third-order Legendre polynomials for the additive genetic, and permanent environment effects. Heritabilities, and genetic correlations were estimated by Bayesian techniques using the Gibbs sampler. Results: All variance components tended to be high in the beginning and the end of lactations. Additive genetic variances for milk, fat, and protein yields were the lowest and were the least variable compared to permanent variances. Heritability values tended to increase with parity. Estimates of heritabilities for 305-d yield-traits were low to moderate, 0.14 to 0.2, 0.12 to 0.17, and 0.13 to 0.18 for milk, fat, and protein yields, respectively. Within-parity, genetic correlations among traits were up to 0.74. Genetic correlations among lactations for the yield traits were relatively high and ranged from $0.78{\pm}0.01$ to $0.82{\pm}0.03$, between the first and second parities, from $0.73{\pm}0.03$ to $0.8{\pm}0.04$ between the first and third parities, and from $0.82{\pm}0.02$ to $0.84{\pm}0.04$ between the second and third parities. Conclusion: These results are comparable to previously reported estimates on the same population, indicating that the adoption of a random regression TD model as the official genetic evaluation for production traits in Tunisia, as developed by most Interbull countries, is possible in the Tunisian Holsteins.

This study was conducted to identify the characteristics of pain, self-esteem, perceived health status, and self-efficacy and its influencing factors in patients with chronic arthritis. The data were obtained from 104 patients with chronic arthritis registered in one university hospital in Seoul, from May to August, 2000. For analysing the data, SAS program was used for t-test, ANOVA, Scheffe test, Pearson correlation, and stepwise multiple regression. The results were as follows: 1. The variables which showed significant difference with pain were sex, number of painful joints. 2. The variables which showed significant difference with perceived health status were age, diagnosis. number of painful joints. 3. The variables which showed significant difference with self-efficacy were duration of disease, number of painful joints. quality of sleeping. 4. Moderate negative correlation were observed between pain and perceived health status, self-efficacy, and low positive correlation was observed between self-esteem and perceived health status. Also self-esteem revealed moderate positive correlation with self-efficacy, and moderate positive correlation was observed perceived health status and self-efficacy. 5. The predictors to explain self-efficacy were number of painful joints, self-esteem, duration of disease, duration of exercise and pain. These predictors explained $36.05\%$ of variance of self-efficacy. In conclusion, the nursing intervention to improve self-efficacy for chronic arthritis patients focused not only physiological symptoms such as pain. but also psychosocial factors such as self-esteem.

1) Background: The hospitals of modem society, like any other business entities, have to constantly strive to secure their survival from aggressive changes and competition outside. In this unstable environment, effective leadership is one of the most effective strategies for securing organization's growth as well as stability. This study investigated types of leadership (transformational or transactional) that is dominant in medical record departments and compared it's effects on organizational commitment and job satisfaction of their organizational members by types. 2) Method: A questionnaire was developed and mailed to all medical record administrators working at general hospitals throughout the country except department directors (N=450). Of these, 150 useable questionnaires were returned and analyzed by t-test, multiple regression analysis using SPSS. 3) Results: The organizational commitment and job satisfaction were a little bit higher than moderate level, and that of leadership perceived by medical record administrators was also in moderate level throughout types. Significant characteristics (positively) related to organizational commitment and job satisfaction by univariate analysis were marital status (married), position (middle management) and both type of leadership. However transformational leadership was the only significant factor in leadership styles after considering all the factors related to organizational commitment and job satisfaction together by multivariate analysis. 4) Conclusion: The average organizational commitment and job satisfaction of medical record administrators was just in moderate level. Efforts should be made to increase them by improving leadership capacity of medical record directors, primarily by using transformational leadership approach.

Moderate alcohol consumption has been known to be associated with reduced risk for coronary heart disease (CHD). We assessed the association between alcohol consumption and CHD-related risk factors [hypertension, diabetes mellitus (DM) , high total cholesterol, high triglyceride (TG), low HDL-cholesterol (HDL-C), and high LDL-cholesterol (LDL-C)] in Korean. After excluding those with extreme intake values, the number of final subjects included in the analysis was 4,662 Korean adults aged over 20 years (1,961 men, 2,701 women) who participate in the 2005 Korean National Health and Nutrition Examination Survey. The subjects were divided into four or five groups; none-alcohol consumption group, moderate alcohol consumption group (<15 or 15.0-29.9 g/d), heavy alcohol consumption group (30-69.9 g/d or ${\geq}$ 70 g/d in men, ${\geq}$ 30 g/d in women). Odds ratios (ORs) were estimated from logistic regression adjusting for potential covariates. Alcohol consumption was inversely associated with low HDL-C in both men and women. However, heavy alcohol intake (${\geq}$ 70 g/d) significantly increased risk for hypertension, DM, and hypertriglyceridemia in men. The frequency of alcohol intake was also associated with CHD risk. The risk for low HDLC was decreased with alcohol consumption (${\geq}$ 1 times/wk), but frequent alcohol intake (${\geq}$ 4 times/wk) increased the risk for hypertension. This study revealed that moderate alcohol consumption has protective effect on CHD-related risk factors in Korean population.
