The purpose of this study was to examine the effects of delirium prevention program in patients after hip joint surgey. A non equivalent control group post-test only design was utilized. Sixty four patients aged 65 and older who admitted to a surgical intensive care unit after hip joint surgery were assigned to either a experimental group (n=33) or a control group (n=31). The experimental group was provided with delirium prevention program consisting of orientation intervention, activity intervention, physiological intervention, nutritional intervention, sleep intervention, environmental intervention. Data were analyzed using ${\chi}^2-test$ and independent t-test. The experimental group showed lower incidence of delirium than the control group(${\chi}^2=7.048$, p=.008). The experimental group showed lower ICU stay and length of hospitalization than the control group although the difference was not statistically significant. Findings indicate that the dilirium prevention program is effective in reducing incidence of delirium in patients after hip joint surgery and delirium prevention program is recommended as a guide for the prevention of delirium.

Purpose: Transcatheter closure has become an effective therapy in most patients with patent ductus arteriosus (PDA). However, there are difficulties in transcatheter closure of PDA in small children. We reviewed clinical outcomes of transcatheter closure of PDA in children weighing less than 10 kg in a single center. Methods: Between January 2003 and December 2009, 314 patients with PDA underwent transcatheter closure in our institute. Among them, 115 weighed less than 10 kg. All of these patients underwent transcatheter closure of PDA using either COOK Detachable $Coil^{(R)}$, PFM Nit-$Occlud^{(R)}$, or Amplatzer duct $occluder^{(R)}$. A retrospective review of the treatment results and complications was performed. Results: The mean age of patients was $9.1{\pm}5.9$ months (median, 8 months), and mean weight was $7.6{\pm}1.8kg$ (median, 7.8 kg). The mean diameter of PDA was $3.2{\pm}1.4mm$ (median, 3 mm). Complete occlusion occurred in 113 patients (98%). One patient was sent to surgery because of a failed attempt at device closure, and another patient had a small residual shunt after device placement. The average mean length of hospital stay was $3.0{\pm}3.3$ days, and mean follow-up duration was $21.0{\pm}19.6$ months. There were no major complications in any of the patients. Conclusion: Transcatheter closure of PDA is considered safe and efficacious in infants weighing less than 10 kg. With sufficient experience and further effort, transcatheter closure of PDA can be accepted as the gold standard of treatment for this group of patients.

Mt. Apsan is well known to be one of the most popular tourist sites around Daegu. Annually, more than 16 million persons visit Mt. Apsan. Although, in the mountain there are varieties of geomorphic and geological resources, there has been less concern to utilize the resources for geo-tourism. For example, there are about 10 valleys within Mt. Apsan and various landforms are scattered around the valleys. In this context, this study, based on field surveys centering around Gosangol valley, Anjiranggol valley and Dalbigol valley, focuses on exploring ways towards developing Mt. Apsan as an example geo-tourist site. The main findings are as follows: 1) The main landforms of Mt. Apsan include river cliff, cavern, free face, mud crack, ripple mark, fold, sheeting joint, talus, alluvial fan, pot hole, fault line, gnamma, columnar joint and metamorphic rock. 2) The guide notes on the landforms are developed. 3) In order to raise a learning effect of visitors on geomorphic resources, 9 nature trails are designed according to valleys and the length of visitor's stay.

Introduction: This study was conducted to investigate patients' satisfaction with hospital services at a university hospital in G city. Methods: The subjects of this study were 92 inpatients and data were collected during the period from March to April 2003. The research tool used was a 24-item scale(Cronbach' a= .768) on patients' satisfaction with two subcategories of services: 18 items on hospital human resources(a= .722) and 6 items on hospital environment(a= .700). Data were analyzed through $x^2$-test, t-test and ANOVA using SPSS/PC. Results: The level of patients' satisfaction was $38.4{\pm}3.77$ on hospital services $27.6{\pm}6.14$ on hospital human resources, and $10.8{\pm}2.39$ on hospital environment on the average. Satisfaction related to hospital human resources was higher in male subjects (t = 4.15, p = .003) and in those who stayed longer than 15 days (t= 4.404, p= .039) than the others, and also higher in those who replied that all items related to hospital facilities are satisfactory except the parking lot. Satisfaction related to hospital environment was significantly higher in more educated subjects(F = 2.945, p= .037) and in those who replied that all items related to hospital facilities are satisfactory or appropriate except the parking lot and admission procedure. Conclusions: Length of stay and the level of accessibility and appropriateness of hospital facilities were found to be factors that have significant effects on patients' satisfaction.

Purpose: Acute myocardial infarction (AMI) leads to death if the patient does not receive emergency treatment. Thus it is very important to recognize the symptoms in the early stage. The purpose of this study was to identify clusters of symptoms that represent AMI in Koreans. Methods: The study used a retrospective, descriptive design with secondary data analysis. Data were abstracted from 725 medical records of AMI patients admitted from June 1, 2006 to August 15, 2014 at a university hospital. Results: Analysis of the AMI symptoms revealed five symptom clusters; Cluster 1 (n=140): middle chest pain (100%), shortness of breath, and cold sweating, Cluster 2 (n=256): substernal pain (100%), cold sweating, and shortness of breath, Cluster 3 (n=47): substernal pain (95.7%), left arm pain, shortness of breath, cold sweating, left shoulder pain, right arm pain, and the lower neck pain, Cluster 4 (n=212): shortness of breath (28.3%), left chest pain, and upper abdominal pain, and Cluster 5 (n=70): cold sweating (100%), left chest pain, shortness of breath, left shoulder pain, and upper abdominal pain. Length of hospital stay and mortality rate were significantly different according to symptom clusters (F=2.52, p =.040; F=3.62, p =.006, respectively). Conclusion: Symptom clusters of AMI from this study can be used for AMI patients in order to recognize their symptoms at an early stage. The study findings should be considered when developing educational prevention programs for Koreans with AMI.

Background: Empyema is the collection of purulent exudate within the pleural space. Overall, 36%-65% of patients with empyema cannot be treated by medical therapy alone and require surgery. Multiloculated empyema is particularly difficult to treat with percutaneous drainage. Therefore, we describe our experiences with early aggressive surgical treatment for rapid progressive multiloculated empyema. Methods: From January 2001 to October 2015, we retrospectively reviewed 149 patients diagnosed with empyema who received surgery. The patients were divided into 2 groups according to whether they underwent emergency surgery or not. We then compared surgical outcomes between these groups. Results: The patients in group A (emergency surgery, n=102) showed a more severe infectious state, but a lower complication rate and shorter length of hospital stay. The incidence of lung abscess was higher in group A, and abscesses were associated with diabetes and severe alcoholism. Conclusion: Early aggressive surgical treatment resulted in good surgical outcomes for patients with rapid progressive multiloculated empyema. Furthermore, we suspect that the most likely causes of multiloculated empyema are lung abscesses found in patients with diabetes mellitus as well as severe alcoholism.

Background: We aimed to investigate the preoperative, operative, and postoperative factors affecting intra-aortic balloon pump (IABP) insertion in patients undergoing isolated on-pump coronary artery bypass grafting (CABG). We also investigated factors affecting morbidity, mortality, and survival in patients with IABP support. Methods: Between January 2002 and December 2009, 1,657 patients underwent isolated CABG in Izmir Katip Celebi University Ataturk Training and Research Hospital. The number of patients requiring support with IABP was 134 (8.1%). Results: In a multivariate logistic regression analysis, prolonged cardiopulmonary bypass time and prolonged operation time were independent predictive factors of IABP insertion. The postoperative mortality rate was 35.8% and 1% in patients with and without IABP support, respectively (p=0.000). Postoperative renal insufficiency, prolonged ventilatory support, and postoperative atrial fibrillation were independent predictive factors of postoperative mortality in patients with IABP support. The mean follow-up time was $38.55{\pm}22.70$ months and $48.78{\pm}25.20$ months in patients with and without IABP support, respectively. The follow-up mortality rate was 3% (n=4) and 5.3% (n=78) in patients with and without IABP support, respectively. Conclusion: The patients with IABP support had a higher postoperative mortality rate and a longer length of intensive care unit and hospital stay. The mid-term survival was good for patients surviving the early postoperative period.

This study examined coping strategies and perceived changes of the Chinese international students in South Korea. A total of 56 Chinese students participated and data was analyzed using the concept mapping method. The results showed that Chinese international students adopted developing language proficiency and using social networks as important coping strategies. They also perceived a wide range of changes including changes in the cultural and personal self. However, the perception of these coping strategies and changes differed by the length of stay. Chinese international students who stayed longer reported using specific coping strategies for mood regulation, which was distinctive from the coping strategies used by students who stayed for a shorter period of time. Students who stayed longer perceived negative changes as well as positive changes, while students who stayed for a shorter period reported predominantly positive changes. The findings indicate that university staff needs to understand and sensitively respond to the distinctive experiences of Chinese international students which vary across time.

Purpose: Outpatient classified total hip arthroplasty (THA) is a safe option for a select group of patients. An analysis of a national database was conducted to understand the risk factors for unplanned discharge to a skilled nursing facility (SNF) or acute rehabilitation (rehab) after outpatient classified THA. Materials and Methods: A query of the National Surgical Quality Improvement Program (NSQIP) database for THA (Current Procedural Terminology [CPT] 27130) performed from 2015 to 2018 was conducted. Patient demographics, American Society of Anesthesiologists (ASA) classification, functional status, NSQIP morbidity probability, operative time, length of stay (LOS), 30-day reoperation rate, readmission rate, and associated complications were collected. Results: A total of 2,896 patients underwent outpatient classified THA. The mean age of patients was 61.2 years. The mean body mass index (BMI) was 29.6 kg/m² with median ASA 2. The results of univariate comparison of SNF/rehab versus home discharge showed that a significantly higher percentage of females (58.7% vs. 46.8%), age >70 years (49.3% vs. 20.9%), ASA ≥3 (58.0% vs. 25.8%), BMI >35 kg/m² (23.3% vs. 16.2%), and hypoalbuminemia (8.0% vs. 1.5%) (P<0.0001) were discharged to SNF/rehab. The results of multivariable logistic regression showed that female sex (odds ratio [OR] 1.47; P=0.03), age >70 years (OR 3.08; P=0.001), ASA≥3 (OR 2.56; P=0.001), and preoperative hypoalbuminemia (<3.5 g/dL) (OR 3.76; P=0.001) were independent risk factors for SNF/rehab discharge. Conclusion: Risk factors associated with discharge to a SNF/rehab after outpatient classified THA were identified. Surgeons will be able to perform better risk stratification for patients who may require additional postoperative intervention.
