Waterborne parasite infections are considered a reemerging threat. Most studies on the epidemiology of human cryptosporidiosis, giardiasis, and amebiasis have been carried out in developed countries, and there is little data on the occurrence of these infections in other areas. The objective of this study was to investigate the presence of waterborne parasites such as Cryptosporidium parvum, Giardia lamblia and Entamoeba histolytica in various water samples in Ankara, turkey. A total of 85 samples were examined, 43 from the municipal water supply, 34 from wells, 6 from the Ankara River, and 2 from two untreated dams; by conventional microscopy, immunologically and by polymerase chain reaction (PCR). Oocysts of C. parvum and cysts of G. lamblia were detected by using an indirect fluorescence (antigen) assay, whereas an enzyme linked immunosorbent assay was used to detect the cysts of E. histolytica and E. dispar. In addition, PCR was used for E. histolytica, E. dispar, C. parvum and G. lamblia detection. G. lamblia was found in 2 of the 34 well water samples, and parasites were found in 3 of the 6 Ankara River samples. The 1$\^$st/ contained E. histolytica cysts and Strongyloides stercoralis larvae. the 2$\^$nd/ E. histolytica cysts, and Trichuris trichiura eggs, and the 3$\^$rd/ C. parvum oocysts only. No parasite was observed in the municipal water samples and untreated dam water samples. These results extend our knowledge on waterborne parasites, such occurrence information on waterborne pathogens assists the management and treatment of municipal water.

Anaphylaxis is an acute systemic reaction caused by IgE-mediated immunological release of mediators from mast cells and basophils to allergenic triggers, such as food, insect venoms, and medications. An alternative definition was recently proposed as follows: anaphylaxis is a "condition caused by an IgE mediated reaction" that is "often life threatening and almost always unanticipated." The reaction can be severe enough to lead to the rapid onset of symptoms, including dizziness, upper airway occlusion, bronchial constriction, hypotension, urticaria, cardiovascular arrhythmias and possible cardiac arrest. The incidence or prevalence of anaphylaxis in Korean pediatrics has not known. Thus, Epidemiology of Anaphylaxis in Pediatrics based on the data from Korean Health Insurance Review and Assessment Service (KHIRA) from 2001 to 2007 and questionnaire to the member of Korean Academy of Pediatric Allergy and Respiratory Disease (KAPARD) who are working at the training hospitals was studied. The incidence of anaphylaxis under age 19 is 0.7-1.0 per 100,000 year-person. The causes of anaphylaxis based on data from KHIRA were unknown (61.7%), food (24.9%), medications (12.4%), and serum (1.0%).

The objectives of this study were to understand the relationship between the self-leadership of clinical nurses, nursing organizational culture and nursing performance and identify factors influencing nursing performance. Data were collected from 242 nurses working at H hospital in A Metropolitan City. Data were gatherd collected from Oct 17 to Oct 23, 2016, and analyzed using SPSS 21.0 program. The analysis results showed that several demographic characteristics (i.e., age, marital status, educational level, position, clinical experience and clinical experience in the current department) significantly affected nursing performance. The results of hierarchical multiple regression analysis revealed that clinical experience in the current department and self-expectation are influencing factors in nursing performance and they explained 35.7% of the variance. In order to improve nursing performance, it is necessary to maintain the clinical experience in the current department and develop education programs for enhancing self-expectation of nurses.

Objective: Poor experience with Invisalign treatment affects patient compliance and, thus, treatment outcome. Knowing the potential discomfort level in advance can help orthodontists better prepare the patient to overcome the difficult stage. This study aimed to construct artificial neural networks (ANNs) to predict patient experience in the early stages of Invisalign treatment. Methods: In total, 196 patients were enrolled. Data collection included questionnaires on pain, anxiety, and quality of life (QoL). A four-layer fully connected multilayer perception with three backpropagations was constructed to predict patient experience of the treatment. The input data comprised 17 clinical features. The partial derivative method was used to calculate the relative contributions of each input in the ANNs. Results: The predictive success rates for pain, anxiety, and QoL were 87.7%, 93.4%, and 92.4%, respectively. ANNs for predicting pain, anxiety, and QoL yielded areas under the curve of 0.963, 0.992, and 0.982, respectively. The number of teeth with lingual attachments was the most important factor affecting the outcome of negative experience, followed by the number of lingual buttons and upper incisors with attachments. Conclusions: The constructed ANNs in this preliminary study show good accuracy in predicting patient experience (i.e., pain, anxiety, and QoL) of Invisalign treatment. Artificial intelligence system developed for predicting patient comfort has potential for clinical application to enhance patient compliance.

The unnatural dead body refers to a corpse which is suspicious of unusual death and the dead case has been occurred more than 20 thousands times every year during the recent five years and most of them are found decayed. Police Scientific Investigators investigate unnatural dead bodies and its surroundings in all-around way and determine whether the death is involved with a crime, and most of the Scientific Investigators are exposed to a danger to get infected with pathogenic bacteria which are generated during the decaying process of dead body and are mostly to cause serious injuries on human beings. In line with the fact, the present study conducted a bacterial analysis by collecting excretions from 60 dead bodies and culturing the bacteria to evaluate infection risk of the police agents. The study cultured bacteria from 60 bodies and classified pathogenic bacteria of 108 strains, and its main bacteria are found to be them (; Acinetobacter baumannii 20 strains (19%), Pseudomonas aeruginosa 19 strains (18%), E. coli 18 strains (17%), Klebsiella pneumoniae 11 strains (10%), Proteus mirabillis 10 strains (9%), Enterococcus faecium 10 strains (9%), Staphylococcus aureus 9 strains (8%), Bacillus spp. 5 strains (5%), Streptococcus pneumoniae 3 strains (3%), Candida albicans 2 strains (2%), Mycobacterium tuberculosis 1 strains (1%)). The study results are expected to be used as educational data for preventing the Police Scientific Investigator from infections with bacteria or as a minimum data for improving work environment of the agents.

Purpose: The purposes of this study were to investigate sleep quality and the related factors among clinical nurses. Methods: Data were collected from 208 nurses in general hospitals through self-report. Pittsburgh Sleep Quality Index (PSQI), Korean Epworth Sleepiness Scale (KESS), Insomnia Severity Index (ISS) were used. The data were analyzed t-test, ANOVA, $Scheff{\acute{e}}$ test, and multiple regression using the SPSS 20.0 program. Results: The mean scores of the subjects were $7.58{\pm}3.61$ on daytime sleepiness, $9.93{\pm}6.22$ on insomnia, and $7.29{\pm}3.05$ on sleep quality. The sleep quality in clinical nurses significantly influenced by insomnia (${\beta}=.55$, t=8.14, p<.001), daytime sleepiness (${\beta}=.16$, t=2.83, p=.005), and work satisfaction (${\beta}=-.15$, t=-2.35, p=.020). The three variables explained 55.9% of variance of sleep quality (F=10.73, p<.001). Conclusion: Sleep quality was influenced by daytime sleepiness, insomnia, and job satisfaction. To improve sleep quality, hospitals managers or leaders need to provide sleep promotion programs for preventing daytime sleepiness and insomnia.

Purpose: This study aimed to investigate the impacts of end-of-life care competency and ethical dilemmas on psychological burnout in nurses who care for terminal cancer patients. Methods: A cross-sectional study of 160 nurses who cared for terminal cancer patients was conducted. The participants were recruited from the hospice-palliative care wards, hematology or oncology wards, or intensive care units of three general hospitals in a single metropolitan area. Data were collected using a self-administered survey to assess end-oflife care competency, ethical dilemmas, psychological burnout, and general sociodemographic characteristics. Data were analyzed using descriptive statistics, the independent ttest, analysis of variance, Pearson correlation coefficients, and hierarchical linear regression analysis using SPSS for Windows (version 26.0). Results: Psychological burnout was significantly correlated with end-of-life care competency (r=-0.23, P=0.003) but not with ethical dilemmas. The results of the hierarchical linear regression analysis indicated that endof-life care competency (β=-0.280, P=0.010) and ethical dilemmas (β=0.275, P=0.037) were significant predictors of psychological burnout, after adjusting for age, religious status, clinical experience, and unit type. Conclusion: The current study's findings demonstrate that end-of-life care competency and ethical dilemmas are crucial factors that affect psychological burnout in nurses who care for terminal cancer patients. Substantive education programs must be developed to improve nurses' competencies in end-of-life care and ethical dilemmas to decrease psychological burnout.

Objective : Acupuncture, one of the Oriental medical treatment techniques in East Asia, is growing in popularity all over the world. Based on bibliographical and clinical data, the depth of needling, i.e. superficial or deep needling, has been considered to be a variable as potential modifiers of needling effects, such as localization, manipulation of the needle, or elicitation of DeQi. The purpose of this review is to summarize clinical trials using minimal acupuncture and to evaluate its appropriateness as a control. Methods : A survey of computerized literature searches for randomized controlled trials using minimal acupuncture revealed that a total of 10 studies were published until April 2008. Results : Results obtained from clinical trials showed that acupuncture were more effective than minimal acupuncture in 3 out of 10 trials, while others were no more effective than control. However, minimal acupuncture might neither be a inert placebo nor be indiscriminable. Conclusion : Minimal acupuncture as 'placebo' controls seems misleading and scientifically unacceptable.

Although various criteria on the diagnosis of diabetic neuropathy are applied from trial to trial, being tailored in concert with its purpose, the utmost evidences of the diagnosis are subjective symptoms and objective signs of neurologic deficit. The application and interpretation of auxiliary electrophysiological test including nerve conduction study (NCS) should be made on the context of clinical pictures. The evaluation of the functions of small, thinly myelinated or unmyelinated nerve fibers has been increasingly stressed recently with the advent of newer techniques, e.g., measurement of intraepidermal fiber density, quantitative sensory testing, and autonomic function test. And the studies with those techniques have shed light to the nature of the evolution of diabetic neuropathy. The practical application of these techniques to the diagnosis of diabetic neuropathy in the individual patients, however, should be made cautiously due to several shortcomings: limited accessibility, wide overlapping zone between norm and abnormality with resultant unsatisfactory sensitivity and specificity, difficulty in performing subsequent tests, unproven quantitative correlation with clinical deficit, and invasiveness of some technique. NCS, as an extension of clinical examination, is still the most reliable electrophysiological test in evaluating neuropathy and gives the invaluable information about the nature of neuropathy, whereas the newer techniques need more refinement of the procedure and interpretation, and the accumulation of large scaled data of application to be considered as established diagnostic tools of peripheral neuropathy.
