Objectives: The purpose of this study is to determine the fatigue, self-esteem, and depression of pregnant women with gestational diabetes mellitus (G-DM), and to reveal associated factors of depression. Methods: As a descriptive correlation study, data was collected from 119 pregnant women with G-DM. Data was analysed using t-test, ANOVA, and stepwise multiple regression. Results: Fatigue, self-esteem, and depression averaged $2.09{\pm}.62$ (range of scale 1~4), $2.63{\pm}.32$ (range of scale 1~6), and $0.45{\pm}.25$ (range of scale 0~3), respectively. The depression varied with a statistical significance according to the age (p=.008), employment (p=.014), child (p=.034), and physical and psychological adjustment of pregnancy (p<.001). We also identified fatigue as the most influencing factor and the physical and psychological adjustment of pregnancy as the second most influencing factor, self-esteem as the third, age as the fourth, and child as the influencing factor on the G-DM women's depression. Conclusions: This research provided a valuable opportunity to recognize G-DM as a personal, and societal problem, which calls for relational support as well as personal support. The healthcare providers need to recognize the emotional aspects of the women with G-DM, and make various efforts to promote the physical and psychological health of the G-DM patients.

This study investigated the effect of home environment quality and fathers' parenting participation on school readiness of preschool children. The subjects were 101 5-years old children, mothers and teachers at child care centers located in the Gyeonggi area. Home environment quality was measured using a 'Korean Home Environment' questionnaire. Parenting participation by fathers was measured by 'Scale for Productive Roles of Fathers of Children in Their Early Childhood.' Lastly, the children's school readiness measured the 'School Readiness Inventory.' Collected data were analyzed using t-test, correlation analysis, and hierarchical multiple regression. The results of the study showed that the school readiness of preschool children differed by gender. The score of girls' school readiness was higher than boys' school readiness. Such difference was apparent in the school readiness areas of general knowledge, mathematical knowledge, and adjustment. There was a positive correlation between age and the school readiness of preschool children. An increase in children's age also increased school readiness in the areas of linguistic knowledge, mathematical knowledge, and adjustment. Home environment quality and fathers' parenting participation directly influenced the school readiness of preschool children. The pattern of the results suggests that a desirable home environment and fathers' contribution in the family for children are critical components to prepare preschool children for elementary school.

Objective : Health insurers and policy makers are increasingly examining the hospital mortality rate as an indicator of hospital quality and performance. To be meaningful, a risk-adjustment of the death rates must be implemented. This study reviewed 5 severity measurement methods and applied them to the same data set to determine whether judgments regarding the severity-adjusted hospital mortality rates were sensitive to the specific severity measure. Methods : The medical records of 584 patients who underwent coronary artery bypass graft surgery in 6 general hospitals during 1996 and 1997 were reviewed by trained nurses. The MedisGroups, Disease Staging, Computerized Severity Index, APACHE III and KDRG were used to quantify severity of the patients. The predictive probability of death was calculated for each patient in the sample from a multivariate logistic regression model including the severity score, age and sex to evaluate the hospitals' performance, the ratio of the observed number of deaths to the expected number for each hospital was calculated. Results : The overall in-hospital mortality rate was 7.0%, ranging from 2.7% to 15.7% depending on the particular hospital. After the severity adjustment, the mortality rates for each hospital showed little difference according to the severity measure. The 5 severity measurement methods varied in their statistical performance. All had a higher c statistic and $R^2$ than the model containing only age and sex. There was a little difference in the relative hospital performance evaluation by the severity measure. Conclusion : These results suggest that judgments regarding a hospital's performance based on severity adjusted mortality can be sensitive to the severity measurement method. Although the 5 severity measures regarding hospital performance concurred, more often than would be expected by chance, the assessment of an individual hospital mortality rates varied by the different severity measurement method used.

BACKGROUND/OBJECTIVES: Obesity, which is a known risk factor for many chronic diseases, has also been associated with vitamin D deficiency. This study explored the relationship between serum 25-hydroxy-vitamin D [25(OH)D] concentrations and adiposity measures in a general Korean population using the most recent, nationally representative survey data. SUBJECTS/METHODS: The study sample consisted of 4,771 Korean adults (${\geq}19years$) who participated in the fifth Korean National Health and Nutrition Examination Surveys. Serum 25(OH)D was determined by radioimmunoassay. Body mass index (BMI), waist circumference (WC) and total body fat content were measured as adiposity measurements. Total body fat content was measured by dual-energy X-ray absorptiometry. RESULTS: The serum 25(OH)D level was significantly higher in men than in women. Serum 25(OH)D concentration was positively correlated with energy intake, and it was negatively correlated with total body fat content (P < 0.0001) and percentage body fat (P < 0.0001) after adjustment for age in both sexes, while was inversely correlated with BMI only in women. In multivariable regression analysis, serum 25(OH)D was inversely associated with the total body fat content after adjustment for age, BMI, education, region, smoking, alcohol consumption, physical activity, and energy intake only in men (P = 0.0047). However, the serum 25(OH)D concentration was not associated with WC or BMI, indicators of adiposity after adjustment for potential risk factors. CONCLUSIONS: Serum 25(OH)D concentration was independently associated with the total body fat content in a general Korean population, but it may be not associated with the indicators for estimating adiposity, such as WC or BMI.

This study was conducted to develop a novel adjustment factors for 305 days using 138,103 lactation records and 1,770,764 daily records, which were based on environmental circumstances such as herd year, season, age at calving, dry period and lactating stages. The present study showed that the change of persistency of cows at the first parity from total lactacting characteristics was slowly processed, while it was rapidly changed in cows at the second parity stage. Particularly, there was an outstanding difference between the first and second parity cows. Milk yield and composition increased as the age at calving was increased. In addition, milk yield and composition were higher at the first parity on fall compared with others, and those were higher at the more than second parity on fall and winter compared with other parity stages and seasons. The cow of dry group was included into lactating records of more than second parity stage. The data indicated that optimal results arose from 45-70 days of dry period. Milk yield was decreased when dry period was longer or shorter than 45-70 days. The lactating days were divided into 17, 28 and 38 stages to compare the multiplicative correction factors. The factor was effective at 28 stages on the first parity. The total correlation coefficients were 0.93832, 0.95058 and 0.95076 at the present correction factor, 17 stage and 28 stage, respectively. At second parity, the factor was higher in dry group 1 and 3 at 17 stage, and it was higher in dry group 2 at 28 stage compared with others. Therefore, the present study showed that the percent squared bias (PSB), which was calculated from the novel correction factor, was better than previously used correction factors. Also, the present study indicated that the bias of the novel correction factor was improved, and this factor could be more accurate compared with others.

The purpose of this study was to investigate the psychological wellbeing as applied to the bioecological family life welfare model, concerning individual attributes, family backgrounds, and family processes across the family life cycles. Based on Bronfenbrenner's bioecological perspective, the "bioecological family welfare model", which includes person (individual attributes), context (family background), process (mechanism - family process), and time (the family life cycles), was applied as a research paradigm for this study. The sample for the questionnaire study comprised for 900 families, considering the family life cycle in Busan and the Kyungnam area. The families were categorized into 6 family life cycles based on Duvall and Hill's family life cycle. For the final analysis, 628 families were used. According to the path analysis results, the length of commitment before marriage and self-esteem had significant effects on the stress coping ability. Several individual attributes and family backgrounds such as age, length of marriage, family life cycle, self-esteem and stress coping ability had significant effects on marital adjustment. The family life cycle and age were significant variables on family function. The significant variables on psychological wellbeing were monthly income, length of commitment before marriage, stress coping ability and marital adjustment. The regression model showed that the variables of the individual attributes, context and family process accounted for 51% of the psychological wellbeing. The results show that the suggested research model was significant and effective to explain the mechanism of psychological wellbeing. Individual attributes and family context have an impact on stress coping, marital adjustment, and family function, which in turn affect psychological wellbeing.

Purpose: The purpose of this study was to identify the influence of self-differentiation, psychological discomfort, and marital dyadic adjustment on maternal-fetal attachment in primigravida. Methods: In total, 108 primigravida participated in this descriptive correlational study. The participants answered self-report questionnaires. Data were collected from January to May, 2020, and were analyzed using descriptive statistics, the t-test, analysis of variance, Pearson correlation coefficients, and hierarchical multiple regression with SPSS for Windows ver. 23.0. Results: The mean age of the primigravida was 31.66 years. The mean score for the degree of maternal-fetal attachment was 76.81 out of 96 points. Participants' scores for maternal-fetal attachment differed significantly based on age (t=2.08 p=.039) and marital status (t=2.05, p=.043). Maternal-fetal attachment was significantly negatively correlated with psychological discomfort (r=-.39, p<.001), and significantly positively correlated with self-differentiation (r=.36, p<.001) and marital dyadic adjustment (r=.36, p<.001). Self-differentiation explained 24.1% of variance in participants' maternal-fetal attachment, and its effect was statistically significant (F=7.79, p<.001). Conclusion: In primigravida, more self-differentiation was associated with stronger maternal-fetal attachment. To strengthen maternal-fetal attachment in primigravidae, educational program that increases the level of self-differentiation and minimizes psychological discomfort may be helpful for first time pregnant women. Additionally, it is recommended to provide nursing interventions to encourage couples to work together throughout the gestational period.

Data were from four institutional herds and four field data collection centers involved in a progeny testing program for Nili-Ravi buffaloes in Pakistan. The REML with a single trait animal model, employed on 2,353 lactations, from 901 daughters of 66 sires, gave a heritability estimate of 0.18 for milk yield with repeatability (between lactations) of 0.43. Estimated milk yield was highest at 65 months of age for the first parity and 81 months for later parities. Correction factors for age at calving, standardized to 60 months in the second and later parities, were developed.

The authors examined for risk factors for suicide among psychiatric patients who had committed suicide through the analysis of demographic, clinical and psychological characteristics of the patients. The total number of suicides committed during social adjustment period was 9. Male and female ratio was 5:4 and the highest incidence occurred in the age group of 21-29 years. Of the 9 cases, schizophrenia accounted for two-third of the suicides. Among the committed suicides, 4 were in hospitalization and rest were postdischarge state. We found that 4 of 5(80%) suicides occurred in the first year after discharge, and that three fifth(60%) occurred within three months of discharge. In this result, most of suicides occurred immediately or soon after discharge and some during inpatient care. The major precipitating factors the patients showed before committing suicide were realistic and psychological problems. Consquently, they become dejected, experience feelings of hopelessness, go on to a depressed mood, and, in that case, have suicidal ideas that are eventually acted on. We believe that the ability to recognize risk factors for suicide and develop appropriate interventions is key to suicide prevention.
