Background: It is widely acknowledged that single bedrooms have many potential advantages compared to multiple bedrooms. However, Korea has a reimbursement system that patients have to pay the additional fee if they will use single bedroom or pay-bed (1-3 bedroom). There is little research on patients' bed selection and relationship between patient satisfaction and bed type in the Korean setting. Methods: Using the 2017 Korea Health Panel (KHP) Survey data, we modified bed type by two dichotomous variables: single bedroom vs. multiple bedroom (2+ bedrooms) and pay-bed (1-3 bedroom) vs. reimbursed bed (4+ bedroom). Multivariate logistic regression is performed to determine the factors affecting the patient's choice of room types. Multivariate regression analysis was conducted to examine how hospital room types are affecting patient satisfaction. Results: Single room and pay-bed (1-3 bedroom) use was influenced by patient age (19- years old), male, a person at work, hospitalizing in a clinic, and birth. After controlling variables of the behavioral model of medical utilization, the association between patient satisfaction and use of single bedroom & pay-bed (1-3 bedroom). Cause of hospitalization, major treatment, and recognition of unnecessary care are statistically significant variables on patient satisfaction. Conclusion: Although the single room is about the standard for newly built hospitals in western countries, it remains unclear that single room or pay-bed (1-3 bedroom) has positive effects on patient's outcomes and satisfaction. In this empirical study, the difference in patient satisfaction by bedroom type was not noticeable. In terms of bed management by hospital staff, securing patient credibility in hospital care is an important task. Patients' perception of whether medical staffs have encouraged unnecessary treatment or tests has a significant impact on patient's satisfaction.

Cancer show distinct pattern of gene expression when it is compared to normal. This difference results malignant characteristic of cancer. Many cancer drugs are targeting this difference so that it can selectively kill cancer cells. One of the recent demand for personalized treating cancer is retrieving normal tissue from a patient so that the gene expression difference between cancer and normal be assessed. However, in most clinical situation it is hard to retrieve normal tissue from a patient. This is because biopsy of normal tissues may cause damage to the organ function or a risk of infection or side effect what a patient to take. Thus, there is a challenge to estimate normal cell's gene expression where cancers are originated from without taking additional biopsy. In this paper, we propose in-silico based prediction of normal cell's gene expression from gene expression data of a tumor sample. We call this challenge as reverting the cancer into normal. We divided this challenge into two parts. The first part is making a generator that is able to fool a pretrained discriminator. Pretrained discriminator is from the training of public data (9,601 cancers, 7,240 normals) which shows 0.997 of accuracy to discriminate if a given gene expression pattern is cancer or normal. Deceiving this pretrained discriminator means our method is capable of generating very normal-like gene expression data. The second part of the challenge is to address whether generated normal is similar to true reverse form of the input cancer data. We used, cycle-consistent adversarial networks to approach our challenges, since this network is capable of translating one domain to the other while maintaining original domain's feature and at the same time adding the new domain's feature. We evaluated that, if we put cancer data into a cycle-consistent adversarial network, it could retain most of the information from the input (cancer) and at the same time change the data into normal. We also evaluated if this generated gene expression of normal tissue would be the biological reverse form of the gene expression of cancer used as an input.

This study was done to determine the relationship between the anxiety levels of hospitalized psychiatric patients and various influencing variables. The purpose of this study was to determine factors that may help hospitalized psychiatric patients to experience lower levels of anxiety in relation to changing situations and provide the basic data for a dynamic approach which is important in the field of modern psychiatric nursing that understands and analyses the meaning of patients behavior. The anxiety may produce stress, which is a common experience among all human beings. Patients may merely feel uncomfortable in the state of mild anxiety, however, the severe state could be an obstacle to treatment and recovery from disease. The anxiety of the psychiatric patient is a factor which greatly influencing the patient's behavior, so his disorderd behavior is an expression of defence or pathologically fixed behavior. According the psychiatric patient's anxiety at the time of admission is the concern of the health team. The nurse's special concern has to do with understanding and supporting the patient and meeting his individual needs by frequent close contact during the entire hospitalization period, compared to other teamembers the nurse's responsibility in this regard is greated. So this study emphasizes the necessity of creating conditions these, but above all the psychiatric nurse should create a therapeutic environment by not only regarding the patient's behavior or symptoms but understanding the meaning of them. The subjects of this study were 57 psychiatric patients selected from the K neuropsychiatric hospital located in Kunsan city. Data were collected twice from the same patients within a 24 hour period after admission and 10 days after admission. (September 18th to November 8th, 1980). The data collected method was through direct interview, and the interview time was 20 minutes for each patient. Data analysis included Item Analysis & Internal Consistency Reliability Tests, Percentages, t-test, analysis of variance and stepwise multiple regression analysis. The findings of this study were as follows. A. Test of Hypothesis a. Hypothesis 1 :“The anxiety level of psychiatric patients within 24 hours after admission will be higher than those of the same patients 10 days after admission,”was accepted. (t = 3. 15 ; p < 0.005) b. Hypothesi 2:“The more the number of admissions the higher the level of anxiety related to two categories”, was accepted. (affective anxiety: F = 5.50, p < 0.005, Somatic anxiety: F = 9.12, p <.

Purpose: This study was done to explore the relationship between perceived patient safety culture and patient safety management activities among health personnel. Methods: This study was a cross-sectional survey. Participants were 342 health personnel working in two tertiary hospitals. Self-administered questionnaires were used to collect data from a convenience sample of 254 nurses and 88 doctors. Results: Scores on participants' perceived patient safety culture and patient safety management activities were just over the mean. There were significant differences in patient safety management activities by type of occupation, nurses' position, length of service, and work week. Doctors scored perceived patient safety culture and patient safety management activities significantly lower than nurses. In addition, perceived patient safety culture was significantly related to patient safety management activities. Factors which influence participants' patient safety management activities were communication, type of occupation, overall evaluation of patient safety, supervisor/manager, frequency with which events were reported, and nurse's position. Conclusion: Findings provide significant evidence that patient safety management activities are associated with perceived patient safety culture. Therefore, to build a positive safety culture, health personnel, especially doctors and general nurses need to visibly commit to patient safety management activities and be role models to ensure patient safety.

The purpose of this study is to investigate the correlation among the stroke patient family's health, burden and quality of life which is based upon the comparative appreciation of the adult stroke patient's family and elderly stroke patient's family. For this purpose, data were collected from the family care-givers for two groups of stroke patients under sixty years old and over sixty years of age, admitted at K Hospital and H Hospital in Seoul. The instruments for this research are based on the tool for measuring physical health and psychological health developed by Yang, Young-hee(1992), the tool for measuring the sense of burden by Seo, Mee-hae and Oh, Ga-sil(1993), and the tool for the quality of life by Noh, Yoo-ja(1988). The sampling for this study was done from December, 2000 until February, 2001. Questionnaire data were drawn up by personal interviews aided by the staff nurses. The analysis of collected data are based on general characteristics calculated at the rate of 100 percent of the average, t-test, ANOVA(some difference on a level with p<.05 being subsquently confirmed by DMR) for Health Status, Burden, Quality of Life and Pearson Correlation to verify the hypothetical correlation among the subjects. The results of this study are as follows: 1. In the adult stroke patient family, the factors influencing the physical health proved to be age, present occupation and family-formation. Here, the factors influencing psychological health turned out to be age, matrimonial status, present occupation and family-formation. In the elderly stroke patient family, the factors influencing physical health proved to be age, gender, final academic status, matrimonial status, present occupation, and relation with the patient. Here, the factors influencing the psychological health were age, final academic status, matrimonial status, present occupation, relation with the patient and family-formation. In the former case, the influencing factors upon the burden were shown to be age, final academic status, matrimonial status, relation with the patient and family-formation. In the latter case, the influences upon the burden were age, gender, final academic status, matrimonial status, present occupation and relation with the patient. In the former case, the influences on the quality of life were gender, and economic situation. In the later case, the influencing factors on the quality of life were age, final academic status, matrimonial status, present occupation, and relation with the patient. 2. The rate of the physical condition in the former case turned out to be 2.83, and the psychological condition 2.37. The physical condition of the latter case was 2.76, and the psychological condition 2.46. The rate of the burden in the former case was 3.14, and that of the latter case was 3.04. The rate of quality of life in the former case proved to be 2.46, and that of the latter case 2.55. 3. The rate of correlation between the burden and the quality of life appeared to be the high counter-correlation (r= -.573). The rate of correlation between the psychological health and the burden of a simialr (r= -.565). The rate of correlation between the physical health and the psychological health proved to be a moderate correlation (r= .372), The rate of correlation between physical health and the burden turned out to be a low counter-correlation (r= -.276). According to this study, there proved to be a very close correlation among the stroke patient family's health, the burden and quality of life. Thus, it would be necessary to find out various nursing interventions in order to mitigate the stroke patient family's burden in the process of caring for the patients.

This study examined the influence of patient safety culture and safety care activities of general hospital nurses. The participants were 178 nurses working in a hospital in D and G cities. Data were collected from June to July, 2015 through Questionnaires that included the Measure of Patient Safety Culture by Kim et al.(2007), and the Measure of Safety Care Activities by Lee(2009). The collected data were analyzed by descriptive analysis, t-test, One-way ANOVA, Pearson correlation coefficients, and stepwise Multiple regression. A statistically significant positive relationship was observed between the nurses perception of the patient safety culture and their safety care activities (r=.407, p<.001). The findings show the patient safety culture accounted for 43.3% of the variance in the safety care activities for hospital nurses followed by the importance of hospital work environment among nurses to improve the safety care activities. These findings highlight the need to develop effective programs to improve the perception of patient safety culture and safety nursing guideline.

Purpose: This study was conducted as a direct investigation of the data in the dispatch logbooks and status of patient transportation provided by private emergency transport companies in Busan. Methods: This study was conducted using SPSS 23.0 version for a total of 1,000 processed records of private emergency ambulance services in Busan from September 23, 2017 to November 5, 2019. Results: First, 100% of the emergency patient transfers by private emergency ambulances were carried out between medical institutions; 76.4% of all transfer patients had emergency conditions, and 86.0% had serious diseases. Second, 59.3% of the emergency patients were located at distances less than 10 km and 43.2%, at more than 10 km from the medical institutions. Third, 63.5% of the passengers were accompanied by first-class emergency rescuers according to the severity of the condition. Fourth, 92.7% of the reasons for the selection of medical institutions were transferred to places where professional care was available, accounting for most of the reasons for the selection. Finally, the medical institutions were selected according to the severity of the patient's condition; 76.5% patients were transported to institutions with a large number of doctors, and 42.9% of those were transported to specialized care institutions. Conclusion: This study collected data from 1,000 dispatch records of private emergency transport companies in Busan; these records reflect the government's policies to improve the emergency patient transfer system. The current status of emergency patient transfer offered by private transport companies was analyzed. All of the emergency patient transfers were carried out between medical institutions, and 76% of the transferred patients had emergency conditions.
