In spite of effective curative therapy, morbidity and mortality remain high for hospitalized patients with tuberculosis(TB) in Korea. The purpose of this study was to identify patient and hospital characteristics associated with hospital care outcome. Using annual patient survey data produced by Korea Institute for Health and Social Affair, we identified 8,562 hospital discharge with primary diagnosis of TB. Logistic regression analyses were performed on a model that included age, gender, residence area, insurance status, hospital admission source, length of stay, hospital ownership and class of hospital as the explanatory variables and outcome of treatments as the dependent variable. The results show that negative outcome was associated with the patients older than 65 years, medical aid beneficiary, admission through emergency department, and the patients admitted to public owned hospitals. On the other hand, the patients who were admitted to teaching hospitals were associated with positive outcome. To improve hospital treatment outcome of TB patients, more vigorous strategies should be implemented targeting the older and poor population in regard to social support as well as the clinical management and prevention.

Purpose: This descriptive correlation study was conducted to investigate factors affecting the absence of adult workers according to their gender. Methods: Secondary data analysis was carried out using data from the fifth Korean Working Conditions Survey. Data on respondents' demographic characteristics, working conditions, health status, and absence were analyzed; a descriptive analysis, χ²-test, t-test, and logistic regression analysis were carried out. Results: The factors that had the greatest impact on male workers' absence from work were service workers (2.74 times; B=.99), having more than 53 hours of work per week (1.17 times; B=.52), and when subjective health conditions were not satisfied (2.27 times; B=.82), whereas the factors that affected female workers' absence the most were a monthly income of 3 million won or more (2.74 times; B=1.34), a weekly work time of 53 hours (2.02 times; B=.71), and having a fewer number of sleep disorders (B=-.36). Conclusion: This study suggests that not only the national interest should be considered in investigating the factors affecting absence but also the enterprise. Systematic support for the health care of workers is also needed.

Purpose: This study was to identify factors predicting the occurrence of depression among patients with hepatitis C treated with Peg-interferon. Methods: The subjects were 134 patients treated with Peg-interferon after the diagnosis with hepatitis C at the D University Hospital and 3 hospitals located in Busan, South Korea. The predictors of depression were identified by measuring the general characteristics of the subjects and their disease-related characteristics, social support, sleep disorders, and degree of side effects by interferon. The data were analyzed with a t-test, ANOVA, and logistic regression using the SPSS/WIN 18.0 program. Results: Sixty-six point four percent of the subjects suffered from mild to more severe depression. Fatigue, hair loss, itching, and sleep disorders turned out to be significant predictors. In addition, the explanatory power of these variables for the occurrence of depression was 70%. Conclusion: Sleep disorders and drug side effects were determined to have significant influence on the development of depression in hepatitis C patients treated with Peg-interferon. Therefore, the development of nursing intervention programs aimed to prevent depression by effectively managing sleep disorders and side effects is mandated in future to help the given population.

The area under the curve(AUC) is commonly used as a measure of the receiver operating characteristic(ROC) curve which displays the performance of a set of binary classifiers for all feasible ratios of the costs associated with true positive rate(TPR) and false positive rate(FPR). In the bipartite ranking problem where one has to compare two different observations and decide which one is "better", the AUC measures the quantity that ranking score of a randomly chosen sample in one class is larger than that of a randomly chosen sample in the other class and hence, the function which maximizes an AUC of bipartite ranking problem is different to the function which maximizes (minimizes) accuracy (misclassification error rate) of binary classification problem. In this paper, we develop a way to construct the unified framework for AUC maximizer including support vector machines based on maximizing large margin and logistic regression based on estimating posterior probability. Moreover, we develop an efficient algorithm for the proposed unified framework. Numerical results show that the propose unified framework can treat various methodologies successfully.

The objective of this study is to analyze the utilization patterns of other region inpatients in general hospitals located in Seoul area. For the analysis, the study utilize the nationwide data on '2008 Survey of Patients' of Ministry of Health & Welfare. The statistical methodology used in the study is the logistic regression model. This study has three major findings. First, the significant affecting sociodemographic factors in selecting general hospitals located in Seoul area was sex, age, type of payment and inpatients residence region. Second, compared to other disease groups, the inpatients on both 'congenital malformation, deformity and chromosomal abnormalities' and 'neoplasm' groups are more likely to utilize general hospitals in Seoul area. Furthermore, in 'neoplasm' disease group, inpatients with 'bones and articular cartilage malignant neoplasm' are more likely to utilize general hospitals in Seoul area. Finally, hospitals with more than 1,000 beds was chief factor in selecting Seoul-based hospitals by other region inpatients. In conclusion, the study showed that other region inpatients are more likely to utilize general hospitals located in Seoul area in case of severe disease, rare case and surgical case. Therefore, central and local authority is required to monitor local hospitals on quality of the medical service as well as support them to establish specialized medical centers by providing human and physical resources.

This study investigated the prevalence of and risk factors for malnutrition in hospitalized patients in Busan, Republic of Korea. 944 patients (440 men and 504 women) were hospitalized in four Busan general hospitals from March through April, 2011. Nutritional status was assessed on admission by the Nutritional Risk Screening 2002. Data were collected from the electronic medical records system for the characteristics of the subjects, clinical outcomes, biochemical laboratory data, and nutrition support states. Clinical dietitians interviewed the patients using structured questionnaires involving data on weight loss and problems related to oral intakes. Malnourished patients were significantly older (P<0.001) than well-nourished patients, but the values for BMI, serum albumin, total cholesterol, TLC, hemoglobin, and hematocrit were significantly lower (P<0.001) for malnourished than for well-nourished patients. Logistic regression indicated that the main determinant factors for nutritional status were the age, length of stay, BMI, serum albumin, and total cholesterol. In order to increase therapeutic effects of hospitalized patients, clinical dietitians need to offer proper nutritional intervention based on the results of nutrition assessment and identification of malnutrition.
