This chapter studies user interfaces of Web Online Public Access Catalogs (OPACs) and presents their principal difficulties in facing the man-machine interaction and the contributions of Web 2.0 to overcome these limitations. Methodologies used to study OPACs interfaces are examined. A quantitative approach is used to analyze Web OPACs in academic, special, national, and public libraries through the conclusive use of several tests: chi-square or test of independence, logistic regression, odds ratio, analysis of variance, and discriminant analysis. The situation of Latin American Web OPACs is verified in relation to the use of Integrated Library Systems (ILS) and Database Management Systems (DBMS). This methodology is proposed to study the 2.0 functionalities in these catalogs.

This study aimed to identify types and sites of body injury, location of injury occurrence, and the mechanism and severity of injuries in novice and advanced Brazilian jiu-jitsu (BJJ) athletes. One hundred and eight BJJ athletes took part in this study separated in two groups: advanced (n = 53) and novice (n = 55). Athletes answered a questionnaire concerning regions of injury, locality of occurrence, injury severity and mechanism. Chi square test and a logistic regression analysis were used with the level of significance set at p < 0.05. The main results showed that shoulders and knees were the most injury location reported by novice and advanced athletes. Novice athletes demonstrated higher prevalence of injuries during training sessions (54.5%), whereas advanced athletes reported more injuries during competitions (66.1%). Significant associations between novice and advanced athletes were observed for major joints (p < 0.05). The odds ratio of having injury was 70-87% less for novice versus advanced athletes for the major joints cited. We concluded that BJJ athletes demonstrate high prevalence of injury mainly at knee and shoulder. While risk of injury appeared less in novice, the advanced demonstrated higher number of injuries during competitions as a consequence of injured joint keys. By contrast, novice athletes reported higher number of injuries associated with training sessions as a consequence of overuse.

Background: In Tanzania, like in many other poor African countries, cervical cancer is a major problem facing women especially for those aged 30 years and above. This study aimed at constructing a statistical model to enable the prediction of the outcome of treatment for cervical cancer patients in Tanzania. Methods: Data were collected retrospectively from patient’s files with histological proven cervical cancer who were treated at Ocean Road Cancer Institute (ORCI) from year 2009 and followed up to year 2011. The factors considered are screening status, HIV status, disease stage, age, treatment type and the intent of the treatment. The study employed the Chi-square (χ2) test and the logistic regression model for its analysis. Results:  The Chi-square (χ2) test result showed that there was a significant relationship between outcome of treatment and the patient screening status, HIV status, disease stage and intent of treatment at 5% level of significance. On the other hand, the logistic regression results found patient disease stage and intent of the treatment to be statistically significant at 95 percent. Logistic regression results also showed that patients who attended ORCI when their disease at a late stage had an odds ratio of 0.128 less likely to have favorable outcomes compared to those patients who attended ORCI when their disease stage was at early stages. The odds ratio for cervical cancer patients who received both treatment, radiotherapy, and chemotherapy was 2.643 more likely to have favorable outcomes Conclusion:  More emphasis and campaigns should be made in order to encourage women all over the country to attend cancer centers for screening and treatment at early stages or even before any symptoms for cervical cancer and other types of cancers.

En el presente estudio pretendimos analizar las características de los autores de agresiones sexuales cuyo modus operandi es el de atacar a la víctima en portales o entradas de garaje de edificios. Nuestro estudio estuvo orientado a determinar si es posible predecir tales características a partir de los datos de la escena del crimen, analizando casos resueltos. Partiendo del contenido de sentencias judiciales condenatorias dictadas en España, y aplicando pruebas estadísticas de chi-cuadrado, odds-ratio, y regresión logística binaria, hemos obtenido resultados alentadores, en el sentido de que algunas de las variables de la escena del crimen permiten predecir algunas características de los autores. Dado que las variables de la escena del crimen utilizadas aquí son conocidas por el equipo policial al inicio de la investigación, la predicción de características del agresor sexual podría ser de utilidad a la hora de priorizar sospechosos.This paper aims at analysing the features of the perpetrators of sexual assaults whose modus operandi consists of assaulting the victim in doorways or entrances of garage and buildings. Its objective was to determine whether it is possible to predict these features moving from the information regarding the crime scene, by means of analysing solved cases. Moving from the content of convicting judgments issued in Spain, and by applying statistical tests of chi-square, odds-ratio, and binary logistic regression, we have obtained encouraging results, in that some variables in the crime scene allow to predict some features of these offenders. Since the variables of the crime scene that have been used here are known to the police team at the beginning of the investigation, prediction of the sexual offender’s features could be useful to prioritize suspects.

Since 2014, the program to provide masks for Hajj pilgrims from Indonesia in Saudi Arabia as one of the efforts to prevent ISPA, continues to be increased in 2015 Ministry of Health Perform Movement Use Mask (GERMAS). Based on this case, this research focuses on the relationship of Knowledge and Attitude with Mask Usage Behavior among Prayer Hajj Indonesia in Saudi Arabia Year 2016 in preventing the incidence of Acute Respiratory Tract Infection. The design used is cross sectional with quantitative approach. The population in this study is all pilgrims who perform the pilgrimage, amounting to 168,800 people with a sample of 163 respondents. Data analysis techniques include univariate analysis, bivariate analysis with Chi-Square test, and multivariate analysis using multiple logistic regression test. The result of bivariate selection shows that the knowledge variable has no significant correlation with relationship p-value is 0.284 > 0.05. Where as attitude variable have relationship because p-value value 0.000 < 0.05. In multivariate analysis multiple logistic regression test showed that attitude variable which has the most dominant significance with the mask use on haj pilgrims with p-value 0.000 <0.05 and Odds Ratio 3.558. This means that attitude that does not support the use of masks has a 3 times chance of experiencing ISPA events. Abstrak Sejak tahun 2014 program pemberian masker bagi jemaah haji asal Indonesia di Arab Saudi sebagai salah satu upaya pencegahan ISPA, terus ditingkatkan pada tahun 2015 Kementerian Kesehatan melakukan Gerakan Memakai Masker (GERMAS).

This study aims to look at the variables that affect financial sustainability. The data used are banking financial statement data contained in the FSS in 2013 to 2017. The value used to measure financial sustainability is FSS. The value of FSS as the dependent variable is divided into two categories, namely banks that are sustainable and banks that are not sustainable. Response variables used are financial ratios consisting of ROA, ROE, CTD, LTD, DTA, and CTA. The analysis used is logistic regression. Based on the results of the logistic regression model that is formed, a significant variable influences sustainability is ROA and LTA. The odds ratio values ​​for the ROA and ROE variables are 1.2 and 2.2. This means that there is an increasing trend of 1.2 and 2.2 times for better financial sustainability with each added value of ROA and ROE. In other words, the greater the value of ROA or ROE, the greater the possibility of banking for financial sustainability. Chi-square test shows the p-value of 0.27 is greater than alpha. This shows the model meets the goodness of fit. Keywords: Financial Sustainability, Financial Ratio, Logistic Regression, Odds Ratio

Near Death Experiences

AbstractBackgroundNear-death experiences (NDE) occur with imminent death and in situations of stress and danger but are poorly understood. Evidence suggests that NDE are associated with rapid eye movement (REM) sleep intrusion, a feature of narcolepsy. Previous studies further found REM abnormalities and an increased frequency of dream-enacting behavior in migraine patients, as well as an association between migraine with aura and narcolepsy. We therefore investigated if NDE are more common in people with migraine aura.MethodsWe recruited 1037 laypeople from 35 countries via a crowdsourcing platform. Reports were validated using the Greyson NDE Scale.ResultsEighty-one of 1037 participants had NDE (7.8%; CI 6.3-9.7%). There were no significant associations between NDE and age (p>0.6, t-test independent samples) or gender (p>0.9, chi-square test). The only significant association was between NDE and migraine aura: Forty-eight (6.1%) of 783 subjects without migraine aura and 33 (13.0%) of 254 subjects with migraine aura had NDE (p<0.001, chi-square test, odds ratio (OR) = 2.29). In multiple logistic regression analysis, migraine aura remained significant after adjustment for age (p≤0.001, OR 2.31), gender (p<0.001, OR 2.33), or both (p<0.001, OR 2.33).ConclusionsIn our sample, migraine aura was a predictor of NDE. This indirectly supports the association between NDE and REM intrusion and might have implications for the understanding of NDE, because a variant of spreading depolarization (SD), terminal SD, occurs in humans at the end of life, while a short-lasting variant of SD is considered the pathophysiological correlate of migraine aura.

Background: This study researched related causes that make scheduled surgeries canceled not to be conducted and based on the research it is to derive issues in order to reduce surgery cancellation. Methods: We analyzed the association of surgery cancellation with patient characteristics, surgical characteristics and surgery schedule related characteristics, using electronic medical record (EMR) data on surgeries conducted at a university hospital in Korea over 10 years. Additionally, we examined the reasons for surgery cancellation based on patient and hospital characteristics. We used chi-square tests to analyze the distribution of various characteristics according to reasons for surgery cancellation. Multivariate logistic regression analyses were conducted to evaluate the factors associated with surgery cancellation. Results: Among 60,333 cases, surgery cancellation rate was 8.0%. The results of the logistic regression indicated a high probability of surgery cancellation when the patient was too old (odds ratio [OR]: 1.35, 95% confidence interval [CI]: 1.14–1.59), when it was a neurosurgery case (OR: 1.39, 95% CI: 1.21–1.59), when local anesthesia was used (OR: 1.15, 95% CI: 1.07–1.24) or when it was a planned surgery (OR: 2.45, 95% CI: 2.21–2.73). The surgery cancellation rate was lower when the patient was female (OR: 0.87, 95% CI: 0.82–0.93) or when the surgery was related to Obstetrics & Gynecology (OR: 0.53, 95% CI: 0.46–0.60) or Ophthalmology (OR: 0.66, 95% CI: 0.56–0.79). Among the canceled 4834 cases, the surgery cancellation rate for the reasons of patients was 93.2% and the surgery cancellation rate for the reasons of a hospital was 6.8%. Conclusions: This study found that there are related various causes to cancel operations, including patient characteristics, surgery related characteristics and surgery schedule related characteristics and it means that it would be possible for some reasons to be prevented. Every medical institution should consider the operation cancellation as an important issue and systematic monitoring should be needed.
