  • This study attempted to identify important problems of the factors related to the indwelling catheter with closed drainage and to enhance recognization of Urinary Tract Infection management to protect patients with indwelling catheter from UTI. We selected the 58 patients with indwelling catheter with closed drainage from md-surg. intensive care units, and general neurological and neurosurgical ward, in one hospital in Pusan, Korea from May 30 to October 15, 1993. Patients were examined by urinary analysis before inserting catheter and then by urine cultures three times. The obtained data was analized using an SPSS /PC$^{+}$ The statistical analyses employed here was the frequency, percentage and x$^2$-tests. 1. Analyses for Indwelling Catheter induced UTI and infection rates were found to be presented in patients related to the factors of being on antibiotic drugs (x$^2$=14.105, p=.000) and the duration of the indwelling catheter(x$^2$=58.0, p=.000), both of which were found to affect the UTI. 2. UTI rates according to the duration of the in-dwelling catheter were high 8.6% for the 2nd day, 27.6 for the 4th day, and 36.2% for the 7th day, and as the duration for the indwelling catheter was longer, UTI rates were higher. 3. The UTI rates according to the duration of the indwelling catheter related re factors, on the 7th day, were high-52.0% for women, 37.0% for more than 50 years in ages, 30.0% for patients under sur-gery, 33.3% for altered mental states outsides the alert, 76.7% for patients not given antibiotic drugs, 36.4% for less than 3500cc of fluids intakes, it was found that these affected to increase the UTI. 4. Causative organisms of UTI were found ; E.Coli appears the most than all other isolated organisms in women and Klebsiella and Pseudomonas in men. For antibiotic susceptibility of causative organisms, all causative organisms were found to be susceptible to Sul -cefoperazone, Trim-prim, and unasyn and Pseudomonas mostly net susceptible.e.

  • To provide the physician with adequate information to diagnose and treat sleepwalking and sleep terrors, the author reviewed clinical features, epidemiology, causative and precipitating factors, polysomnography, diagnosis, differential diagnosis, and treatment for these disorders. Sleepwalking and sleep terrors have been defined as disorders of arousal that occur early in the night and have their onset during stage 3 or 4 sleep. In both disorders, patients are difficult to arouse, and complete amnesia or minimal recall of the episode is frequent. Genetic, developmental, and psychological factors have been identified as causes of both sleepwalking and sleep terrors. Sleepwalking and sleep terrors typically begin in childhood or early adolescence and are usually outgrown by the end of adolescence. When sleepwalking or sleep terrors have a post-pubertal onset or continue to adulthood, psychopathology is a more significant causative factors. The behavior that occur from deep slow-wave sleep can be painful or dangerous to the individual and/or disturbing to those close to that individual. The assessment of patients suspected of having these conditions requires a thorough medical and sleep history. The most important consideration in managing patients with sleepwalking or sleep terrors episodes is protection from injury.

  • Background: Tarsal tunnel syndrome (TTS) is an entrapment neuropathy that occurs in the ankle. Previous studies reported that this disease was due to physiologic factors and structural lesions in the ankle or foot. The authors investigated the causative factors of TTS and their frequency via operative findings. The diagnostic value of MRI was also evaluated based on the concordance between the operative findings and the MRI findings. Methods: This study was performed in retrospective by using medical record of the patients who underwent operations with TTS from August 2003 to May 2010. Physical examination, nerve conduction study, and MRI were conducted on patients who visited department of neurology or orthopedic surgery due to pain and sensory abnormality of their ankle and foot. Results: 34 patients underwent the operation. Ganglion accounted for the largest portion of the operative findings. In addition, varicose veins, intrinsic foot muscle hypertrophy, tenosynovitis, and fascia thickening were mainly observed. Of the 34 patients, 33 patients underwent pre-operative MRI, of whom 18 patients showed MRI findings consistent with the operative findings. Conclusions: Space-occupying lesions accounted for the majority of the causative factors in TTS patients who underwent the surgical treatment. In this study, the MRI appeared useful for identifying causes of TTS.

  • Client organization inadequate project planning before awarding the contract and insufficient monitoring and control system among the parties involved create severe problems. Ultimately, large-scale projects go beyond the expected cost and time control limits. This paper discusses the major issues involved with a large-scale Hydropower Project in Pakistan Public Sector environment. The latest approved Baseline Plan of project was reviewed and analyzed using Variance Analysis and Trend Analysis techniques in Primavera project management software to assess the efforts made of the parties involved. It was found that Project is 202% Cost overrun and 25% time delays from original contract award. After analysis of baseline plan and quantification of various variance issues in impacted activities, the questionnaire survey was conducted to identify the impact of causative factors. There were almost 17 most significant causative factors identified among 60 identified factors and responsibilities are assigned accordingly. At the end recommendations are made for strategic decisions as lessons learned during project evaluation.

  • Background: With increasing survival periods and diversification of treatment methods, treatment of critically ill cancer patients has become an important factor influencing patient prognosis. Patients with cancer are at high risk of infections and subsequent complications. This study investigated the incidence and factors contributing to the development of ventilator-associated pneumonia (VAP). Materials and Methods: This retrospective study investigated the incidence of VAP and factors leading to infection in patients admitted to the intensive care unit (ICU) of a cancer center from January 1, 2012 to December 31, 2013. Results: The incidence of VAP was 2.13 cases per 1,000 days of intubation, and 13 of 288 patients (4.5%) developed VAP. Lung cancer was the most common cancer associated with VAP (N=7, 53.9%), and longer hospital stays and intubation were associated with increased VAP incidence. In the group using a "ventilator bundle," the incidence was 1.14 cases per 1,000 days compared to 2.89 cases per 1,000 days without its use; however, this difference was not statistically significant (p=0.158). Age (${\geq}65$, OR=5.56, 95% confidence interval [CI]=1.29-23.95), surgery (OR=3.78, 95%CI=1.05-13.78), and tracheotomy (OR=4.46, 95%CI=1.00-19.85) were significant VAP risk factors. The most common causative organisms were methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa (N=4, 30.8% each), followed by Acinetobacter baumannii and Candida albicans (N=2, 15.4% each). Conclusions: The incidence of pneumonia among critically ill cancer patients is highest in those with lung cancer, but lower than among non-cancer patients. The length of hospital stay and time on mechanical ventilation are important risk factors for development of VAP. Although not statistically significant, "ventilator bundle" care is an effective intervention that delays or reduces incidence of VAP. Major risk factors for VAP include age (${\geq}65$ years), surgery, and tracheostomy, while fungi, gram-negative bacteria, and multidrug-resistant organisms were identified as the major causative pathogens of VAP in this study.

  • Objectives: An outbreak of acute febrile illness occurred in the Republic of Korea Air Force boot camp from May to July 2011. An epidemiological investigation of the causative agent, which was of a highly infective nature, was conducted. Methods: Throat swabs were carried out and a multiplex reverse transcriptase-polymerase chain reaction (RT-PCR) assay was performed to identify possible causative factors. Results: The mean age of patients who had febrile illness during the study period was 20.24 years. The multiplex RT-PCR assay identified respiratory syncytial virus (RSV) as the causative agent. The main symptoms were sore throat (76.0%), sputum (72.8%), cough (72.1%), tonsillar hypertrophy (67.9%), and rhinorrhea (55.9%). The mean temperature was $38.75^{\circ}C$ and the attack rate among the recruits was 15.7% (588 out of 3750 recruits), while the mean duration of fever was 2.3 days. The prognosis was generally favorable with supportive care but recurrent fever occurred in 10.1% of the patients within a month. Conclusions: This is the first epidemiological study of an RSV outbreak that developed in a healthy young adult group. In the event of an outbreak of an acute febrile illness of a highly infective nature in facilities used by a young adult group, RSV should be considered among the possible causative agents.

  • This study aims to identify the landslide susceptible zones of Boeun area and provide reliable landslide susceptibility maps by applying different modeling methods. Aerial photographs and field survey on the Boeun area identified landslide inventory map that consists of 388 landslide locations. A total ofseven landslide causative factors (elevation, slope angle, slope aspect, geology, soil, forest and land-use) were extracted from the database and then converted into raster. Landslide causative factors were provided to investigate about the spatial relationship between each factor and landslide occurrence by using fuzzy set and logistic regression model. Fuzzy membership value and logistic regression coefficient were employed to determine each factor's rating for landslide susceptibility mapping. Then, the landslide susceptibility maps were compared and validated by cross validation technique. In the cross validation process, 50% of observed landslides were selected randomly by Excel and two success rate curves (SRC) were generated for each landslide susceptibility map. The result demonstrates the 84.34% and 83.29% accuracy ratio for logistic regression model and fuzzy set model respectively. It means that both models were very reliable and reasonable methods for landslide susceptibility analysis.

  • This literature review was undertaken to explore theoretical models of depression for their potential usefulness in nursing research and practice. Depression has bean accounted for by numerous theories or models of causation ; 11 theories selected from psychology, medicine and psychoanalysis and supported by empirical or experimental research were reviewed. These theories identify a variety of precipitating and predisposing factors that may affect the individual's depression. Aggression - turned - inward theory, object loss theory, ego functioning theory, personality organization theory, behavioral theory, learned helplessness theory, cognitive theory, genetic factors, and biological theories conceptualize predisposing factors. Only life stressors theory identifies precipitating facotrs. Each of these theories contributes to an understanding of depression, but many of them use overlapping and interrelated factors. It is also evident from recent. research that there are multiple causes for depression involving an interactive effect among predisposing and precipitating factors that are both biological and psychological in origin. That is, a single theory is not useful, but perhaps a unified theory could be developed that would be helpful to nursing. This review points to the need for continuing development and testing of theories that would integrate the multiple conceptualizations of depression.

  • It is essential in evaluating the chronic pain patients that the physician obtain a multiple causative factors including organic, psychological, and socioenvironmental factors. Though these multiple factors are involved in the development of chronic pain syndrome, chronic pain syndrome is not only the sum of the interaction of all of these factors, but is also influenced by the sequelae of chronic pain, which again are organic, psychological, and socioenvironmental in nature. Therefore a systemic approach is probably the best way to asses the role of all of these factors. Furthermore, this approach can provide a framework for understanding chronic pain syndrome, for assessing chronic pain syndrome, for the rational management of chronic pain syndrome, and for the development and testing of hypotheses.

  • Delay is one of the most critical issues for construction projects and leads to huge losses in both developing and industrialized countries. The construction sector in Rwanda, a rapidly-developing nation, is no exception. Delays can be mitigated only once we have identify their primary causes, and these may not be the same in each region. This study aims to ascertain the main critical factors responsible for delays in building construction in Rwanda through an intensive literature review and questionnaire survey. A total of 40 delay causative factors were obtained from a literature review and were further classified into nine major categories. The questionnaire survey was distributed to about 80 respondents from clients, contractors, and consultants. From the list of 40 different factors, the top twelve most critical causes were identified as stoppage of work due to cash flow constraints, delay in approving design documents, confidentiality of physical plan, price fluctuations and delay in approving significant change, change orders, delay in performing inspections, Ineffective project planning, inadequate drawing details, unqualified labor, lack of materials on the market and dishonesty.
