Purpose: This study was conducted to analyze intubation survival rates according to characteristics and to identify the risk factors affecting deliberate self-extubation. Methods: Data were collected from patients' electronic medical reports from one hospital in B city. Participants were 450 patients with endotracheal intubation being treated in intensive care units. The collected data were analyzed using Kaplan-Meier estimation, Log rank test, and Cox's proportional hazards model. Results: Over 15 months thirty-two (7.1%) of the 450 intubation patients intentionally extubated themselves. The patients who had experienced high level of consciousness, agitation. use of sedative, application of restraints, and day and night shift had significantly lower intubation survival rates. Risk factors for deliberate self-extubation were age (60 years and over), unit (neurological intensive care), level of consciousness (higher), agitation, application of restraints, shift (night), and nurse-to-patient ratio (one nurse caring for two or more patients). Conclusion: Appropriate use of sedative drugs, effective treatment to reduce agitation, sufficient nurse-to-patient ratio, and no restraints for patients should be the focus to diminish the number of deliberate self-extubations.

Purpose: The purpose of this study was to investigate the variance of sleep quality and factors affecting sleep disturbance among patients with percutaneous coronary angiography in a general hospital. Methods: The subjects of this study was comprised of 101 patients with percutaneous coronary angiography in a general hospital located in B city. Data were collected by a structured questionnaire from November to December 2013. The data were analyzed with descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and stepwise multiple regression. Results: The levels of the participants' sleep quality and sleep disturbance were 4.35 and 5.91 in order of each out of the total score, 10. There was no significant difference in the quality of sleep between intensive care unit and internal medicine unit. Factors influencing sleep quality were 'uncomfortable bed, gown and pillow'(${\beta}=-.279$, p=.003), 'living alone'(${\beta}=-.273$, p=.003), and 'toilet problem' (${\beta}=-.222$, p=.016), which explained 21.5% of the variance (F=10.03, p<.001). Conclusion: The results of this study will provide a basis for improving the sleep quality of patients with percutaneous coronary angiography.

Purpose : This study aimed to provide primary data for developing a program to enhance communication competence by identifying the patient-centered communication competency level of Intensive Care Unit (ICU) nurses and the related factors. Method : Data were collected from August 28th to October 8th, 2015, from 199 ICU nurses working in 30 tertiary hospitals. The study questionnaire included items assessing the patient-centered communication competency of ICU nurses, nursing organizational culture, types of communication, the Teamwork Measurement Tool, the Perceived Nursing Work Environment tool, and the Wong & Law Emotional Intelligence Scale. The collected data were analyzed using descriptive statistics, a correlation test, and a multiple regression. Results : The ICU nurses' mean score on patient-centered communication competency was 3.97 points. The factors influencing the patient-centered communication competency level of ICU nurses were professionalism (p =.002), innovation-oriented organizational culture (p =.015), and emotional intelligence (p<.001). These variables explained 42.2% of the total variance in the patient-centered communication competency of ICU nurses. Conclusion : These findings suggest the need for developing a patient-centered communication competency improvement program that focuses on improving ICU nurses' professionalism and emotional intelligence, and facilitates the creation of an innovation-oriented organizational culture.

This study was designed to provide the base of nursing intervention that could help apheresis blood-donors to promote self-efficacy effectively by analyzing critical factors that influence on this. The subjects recruited for the research were 468 persons who participated in platelet donation at a university hospital apheresis unit in Seoul. The data for this study were collected between May and June, 2002 using questionnaires. Data were analyzed by t-test, ANOVA, Scheffe test, and stepwise multiple regression. The results were as follows. 1. The mean self-efficacy score on the questions related to blood donation was $32.9\pm5.1$, indicating that blood donors have above the mean level of self-efficacy related to blood donation. 2. The self-efficacy score was significantly higher for the group of persons who have more than 5 times of experiences in blood donation than others who have only one experience. 3. The critical factors that influence self-efficacy related to donation were the marital status, educational level. and previous experiences of whole blood donation, while the critical factor that influence on general self-efficacy was previous experiences of whole blood donation. Therefore, it is necessary to establish more effective and organized nursing intervention strategies that can promote the self-efficacy of apheresis blood-donors.

Background: Endometrial cancer is the most common gynecological malignancy among females worldwide, approximately 320,000 women being diagnosed with the disease each year and 76,000 dying. To date, there is limited knowledge of endometrial cancer in Malaysia. Objectives: To identify the epidemiological profile and prognostic factors of survival. Materials and Methods: A list of endometrial cancer patients in 2000-2011 was obtained from the hospital Record Department. Only cases confirmed by histopathology examination were included. We excluded those with incomplete medical records or referral cases. Simple and multiple Cox regression approaches were used for data analysis. Results: Only 108 cases were included with a mean (SD) age of 62.7 (12.3) years, with 87.0% Malay ethnicity. Grade of cancer was: 29.1% grade 1, 43.7% grade 2 and 27.2% grade 3. The majority of patients had non-endometrioid type (60.2%), with myometrial invasion (82.2%) and lymphovascular invasion (57.3%). The significant prognostic factors were age (HR 1.05; 95% CI: 1.02, 1.08, p=0.002) and having lymphovascular invasion (HR 2.15; 95% CI: 1.08, 4.29; p=0.030). Conclusions: Endometrial cancer patients should be diagnosed earlier to reduce the risk of mortality. The public should be given education on the signs and symptoms of the disease.

Oral cancer is a common site of head and neck cancer, and is relatively frequent in Northeast Thailand. The objective of this hospital-based, case-control study was to determine associations with risk factors. A total of 104 oral cancer cases diagnosed between July 2010 and April 2011 in 3 hospitals were matched with control subjects by age, sex and hospital. Data were collected by personal interview. There were significant associations between oral cancer and tobacco smoking (OR=4.47; 95%CI=2.00 to 9.99), alcohol use among women (OR=4.16; 95%CI=1.70 to 10.69), and betel chewing (OR=9.01; 95%CI=3.83 to 21.22), and all three showed dose-response effects. Smoking is rare among Thai women (none of the control women were smokers), but betel chewing, especially among older women, is relatively common. We did not find any association between practicing oral sex and oral cancer.

Purpose: The purpose of this study was to identify vancomycin-resistant enterococcus (VRE) colonization rate in patients admitted to the intensive care unit (ICU), associated risk factors and clinical outcomes for VRE colonization. Methods: Of the 7,703 patients admitted to the ICUs between January, 2008 and December, 2010, medical records of 554 VRE colonized and 503 uncolonized patients were reviewed retrospectively. To analyzed the impact of colonization on patients' clinical outcomes, 199 VRE colonized patients were matched with 199 uncolonized patients using a propensity score matching method. Results: During the study period, 567 (7.2%) of the 7,703 patients were colonized with VRE. Multivariate analysis identified the following independent risk factors for VRE colonization: use of antibiotics (odds ratio [OR]=3.33), having bedsores (OR=2.92), having invasive devices (OR=2.29), methicillin-resistant Staphylococcus aureus co-colonization (OR=1.84), and previous hospitalization (OR=1.74). VRE colonized patients were more likely to have infectious diseases than uncolonized patients. VRE colonization was associated with prolonged hospitalization and higher mortality. Conclusion: Strict infection control program including preemptive isolation for high-risk group may be helpful. Further research needs to be done to investigate the effects of active surveillance program on the incidence of colonization or infection with VRE in the ICU.

The purpose of this study was to determine the level of appropriateness in hospital stays and factors influencing inappropriate hospital stays. The study was conducted at fifteen general care units in a tertiary university hospital. Appropriateness of hospital stay was assessed using Appropriateness Evaluation Protocol by trained head nurses. The total of 447 patient records were reviewed. Among them, 352 patient data were included in the final data set. A unit of observation was patient day. A rate of appropriate hospital stay was calculated per patient as a unit of analysis. Multiple regression analysis was performed to determine the factors affecting inappropriate hospital stay. The eighty-three percent (2030/2651) of hospital stays were evaluated as appropriate. There were significant differences in appropriateness of hospital stay according to patient's age, type of health insurance, medical specialty, and length of stay(p<0.05). In the multiple regression analysis, medical speciality was the most significant factor to predict the inappropriate hospital stay. The study showed a substantial proportion of hospital stay was found to inappropriate. Level of appropriateness was significantly different from medical specialty. Interdepartmental approach should be required to coordinate and improve appropriate resource utilization.

This research has been implemented based on the area of #369 Dowon-dong, Dalseo-gu, Dae-gu which is considered as a place with satisfactory characteristics for the flow of fresh air into the city. Simulations of the target area both prior to the development plan and after apartment complex blocking were analyzed in regard to blocking planning and pilotis based on the main direction of wind, $90^{\circ}$ (east wind) and $180^{\circ}$ (south wind). In addition, congested wind corridor flow in the target place was identified through a pollution spread simulation according to the wind corridor. Therefore, the flow of wind in the one area is affected by the blocking of the complex and the main direction of the wind. Also blocking, in regard of pilotis, provides a better flow of wind. This study was implemented based on wind formation by apartment complex planning, so further study on the other factors affecting the flow of a wind corridor along with block planning and pilotis need to be carried out. Sustainable environmental factors through analysis of the environmental factors have to be analyzed. Moreover, building and complementing fundamental resources and systematic devices should be supported.
