Introduction: Motion sickness is a common problem faced during flying training. Aircrew with persistent motion sickness require motion sickness desensitization. Although many aircrew benefit from the motion sickness desensitization therapy (MSDT), a significant number of individuals fail to complete the desensitization program. Early prediction of desensitization program outcome would identify non-responders and help in increasing the efficiency of MSDT. Material and Methods: A retrospective survey of candidates who underwent MSDT at the Institute of Aerospace Medicine between 2009 and 2019 was done. Coriolis time interval (CTI) values of 28 candidates could be retrieved. Mean CTI values of the successful and unsuccessful candidates at 5 rotations per minute (RPM) were compared. Statistical analysis was done using independent t-test, binary logistic regression, and a receiver operator characteristics (ROC) analysis. Results: The unsuccessful group candidates (M = 14.3, SD = 8.7 s) had significantly higher mean CTI values at 5 RPM than the successful group candidates (M = 6, SD =2.3 s); t (15.09) = −3.43, P = 0.04. Logistic regression indicated that there was a significant association between the CTI values and MSDT outcome, Chi-square (1, n = 26) =12.73, P ≤ 0.001. ROC analysis revealed a statistically significant curve with a good predictive cutoff value for CTI to identify non-responders. Conclusion: Results indicated that CTI values are reliable indicators in predicting the outcome of MSDT. Inclusion of other parameters, both physiological and psychological, that have a good correlation with motion sickness may give us better predictive models. Such predictors will also help in better understanding of the pathophysiology of motion sickness and in formulating improved treatment modalities.

ABSTRACT
The purpose of this paper is to evaluate the validity and reliability of Cognitive Therapy Intervention (CTI) which focusing on the resilience of adolescents with behavioural problems. CTI is developed based on Cognitive Theory and the Sidek Module Development Model. The CTI has eight interventions. The CTI manuscript was distributed to five content experts to determine intervention’s validity. The finding shows that the validity index 0.87 was obtained. Meanwhile, thirty two adolescents were selected to measure the reliability of each intervention by evaluating the objectives in each intervention session. As a result, the reliability index 0.85 was obtained. From these two indexes, the Cognitive Therapy Intervention (CTI) possesses high validity and good reliability, and is ready to use. The intervention implies the counselling intervention in working resilience of adolescents with behavioural behaviour. This CTI is recommended to be used by school counsellor to handle adolescents with behavioural problems.

Background/Aim. Chlamydia trachomatis infection (CTI) is an increasing public health problem worldwide and is the most frequent sexually transmitted infection. Studies conducted in many armed forces worldwide showed that CTI is common within military population and generate significant healthcare costs. The aim of this study was to estimate the prevalence of CTI among members of the Serbian Armed Forces (SAF) and to determine risk factors for this infection. Methods. The study was designed as a cross-sectional survey and consisted of completing a questionnaire and chlamydial testing. The questionnaire was divided into two question groups: one was about demographic/service related characteristics and the other was about behavioral patterns/ habits. Chlamydia trachomatis real time polymerase chain reaction (Real-TM PCR) was used for detection of pathogen genome specific sequence in the male urethral swabs and in the female endocervical swabs. All data collected were used to compare military personnel with and without CTI. Risk factors independently associated with CTI were identified by the stepwise multivariate logistic regression analysis (MLRA) of variables selected by the univariate logistic regression analysis (ULRA), with a limit for entering and removing variables from the model at 0.05. Results. The overall prevalence of CTI was 55 of 356 respondents (15.4%; 95% CI 0.5?2.7%). The ULRA identified that CTI was significantly associated with several characteristics: number of sexual partners during previous year (p = 0.008), knowledge about symptoms of CTI (p = 0.035), tattooing (p = 0.035) and married or in stable relationship (p = 0.022). The MLRA revealed that number of different sexual partners during last year was independent risk factor of CTI (p = 0.026; OR : 0.344; 95% CI: 0.13?0.88). Conclusion. CTI is significant problem in male and female military personnel in the SAF. The number of different sexual partners during previous year was independently associated with CTI. These finding indicates that screening for CTI should be undertaken in the SAF, to reduce rates of CTI in the SAF and to prevent morbidity due to this infection.

Abstract Aims We aimed to assess the novel concept of using the paced PR interval (PRI) on the surface electrocardiogram (ECG) to prove trans-isthmus block after cavotricuspid isthmus (CTI) ablation for typical atrial flutter (AFl). Methods and results Consecutive patients with AFl underwent linear radiofrequency ablation of the inferior CTI (6 o’clock). After AFl termination and/or presumed completion of the CTI line, CTI block was proven by atrial pacing by the ablation catheter medial (5 o’clock) and lateral to the line (7 and 9 o’clock). Corresponding PRIs were measured on the surface ECG. CTI block was assumed, if a sudden increase in the PRI was observed by moving the pacing site from 5 to 7 o’clock, and if the latter was longer than at 9 o’clock. Afterwards, bidirectional CTI block was confirmed by differential pacing. Thirty-one patients (mean age 67 ± 16 years, 81% male) underwent CTI ablation, and 18/31 (58%) were in AFl at the time of ablation (cycle length 249 ± 31 ms). Successful CTI block as defined by the PRI method was achieved in 31/31 (100%), and the mean PRIs during pacing at 5, 7, and 9 o’clock were 203 ± 56 ms, 329 ± 70 ms, and 296 ± 66 ms, respectively. Cavotricuspid isthmus block was confirmed in all patients (100%) by coronary sinus pacing with a reversal of the local activation sequence lateral to the isthmus line. Conclusion The method of PRI analysis on the surface ECG to guide CTI ablation is easy to apply and highly accurate in confirming CTI block. This simple technique enables the novel concept of CTI ablation and proof of block with a single catheter.

Blunt aortic injury (BAI) after chest trauma is a potentially lethal condition. Rapid diagnosis is important to appropriately treat patients. The purpose of this study was to compare CT with intravenous contrast (CTI) to CT with angiography (CTA) in the initial evaluation of blunt chest trauma patients. This was a retrospective review of all blunt trauma patients who received a CTI or CTA during the initial evaluation at an urban Level I trauma center from January 1, 2010 to December 31, 2013. Two-hundred and eighty-one trauma patients met inclusion criteria. Most, 167/281 (59%) received CTI and 114/281 (41%) received CTA. There were no differences between cohorts in age, gender, initial heart rate, systolic blood pressure, and Glasgow Coma Scale in emergency department. Mortality rates were similar for CTI and CTA (4% vs 8%, P = 0.20). CTI identified an injury in 54 per cent compared with 46 per cent in CTA ( P = 0.05). Overall, 2 per cent of patients had BAI with similar rates in CTI and CTA (2% vs 2%, P = 0.80). BAI was not missed using either CTI or CTA. Trauma patients studied with CTI had similar diagnostic findings as CTA. CTI may be preferable to CTA during the initial assessment for possible BAI because of a single contrast injection for whole body CT.

Este artigo versa sobre as atividades de ensino e aprendizagem prática em um Centro de Tratamento Intensivo Geral de um hospital público universitário do Rio de Janeiro. A formação profissional do médico não consiste apenas na incorporação de novos conhecimentos, pois é nos estágios práticos que o estudante é forjado como profissional. Em pesquisa etnográfica - centrada no processo de tomada de decisões médicas referentes à vida, sofrimento e morte dos doentes internados no CTI, as atividades de ensino e de aprendizagem revelaram-se de grande importância. A construção de uma identidade profissional médica no estágio em CTI compreende a aquisição de novas formas de ver e descodificar o corpo humano à luz de múltiplos saberes, novos modos de comunicação, como também das formas de gestão das emoções construídas pela equipe. Ao longo deste processo de aprendizagem médica, o estudante deve aprender a se posicionar diante de dilemas éticos, particularmente relevantes em um CTI.

Today threat landscape evolving at the rapid rate with many organization continuously face complex and malicious cyber threats. Cybercriminal equipped by better skill, organized and well-funded than before. Cyber Threat Intelligence (CTI) has become a hot topic and being under consideration for many organization to counter the rise of cyber-attacks. The aim of this paper is to review the existing research related to CTI. Through the literature review process, the most basic question of what CTI is examines by comparing existing definitions to find common ground or disagreements. It is found that both organization and vendors lack a complete understanding of what information is considered to be CTI, hence more research is needed in order to define CTI. This paper also identified current CTI product and services that include threat intelligence data feeds, threat intelligence standards and tools that being used in CTI. There is an effort by specific industry to shared only relevance threat intelligence data feeds such as Financial Services Information Sharing and Analysis Center (FS-ISAC) that collaborate on critical security threats facing by global financial services sector only. While research and development center such as MITRE working in developing a standards format (e.g.; STIX, TAXII, CybOX) for threat intelligence sharing to solve interoperability issue between threat sharing peers. Based on the review for CTI definition, standards and tools, this paper identifies four research challenges in cyber threat intelligence and analyses contemporary work carried out in each. With an organization flooded with voluminous of threat data, the requirement for qualified threat data analyst to fully utilize CTI and turn the data into actionable intelligence become more important than ever. The data quality is not a new issue but with the growing adoption of CTI, further research in this area is needed.

Blunt aortic injury (BAI) after chest trauma is a potentially lethal condition that requires rapid diagnosis for appropriate treatment. We compared CT with IV contrast (CTI) with CT with angiography (CTA) during the initial phase of care at an urban Level I trauma center from January 1, 2010 to December 31, 2013. Overall, 281 patients met inclusion criteria with 167 (59%) CTI and 114 (41%) CTA. There were no differences between cohorts in age, gender, initial heart rate, systolic blood pressure, and Glasgow Coma Scale. Mortality rates were similar for CTI and CTA (4% vs 8%, P = 0.20). CTI identified any chest injury in 54 per cent of patients compared with 46 per cent with CTA ( P = 0.05). The rate of BAI was similar with CTI and CTA (2% vs 2%, P = 0.80), and neither modality was falsely negative. We conclude that CTI and CTA are similar at evaluating trauma patients for BAI, although CTI may be preferable during the initial assessment phase because the contrast injection may be combined with abdominal scanning and image time is reduced when whole-body CT is required.

Abstract Sodium citrate has been used as an anticoagulant to prepare blood and fractions for over 100 years. Its use is sufficiently common that many investigators do not differentiate anticoagulated blood from blood per se. To evaluate the influence of citrate anticoagulation on the dynamics of the blood coagulation process, we compared the properties of blood, platelet rich plasma (PRP) and platelet poor plasma (PPP) prepared and stimulated using standard citrate/Ca++ reconstitution methodologies with matching samples in which transient anticoagulation without disruption of Ca++ homeostasis was achieved by blockade of the contact pathway (using corn trypsin inhibitor (CTI) or inhibitory antibodies to factor XIa). Phlebotomy blood was collected into citrate, CTI or CTI supplemented with citrate, the latter combination establishing conditions in which the effects of citrate anticoagulation in the absence of contact pathway contributions could be studied. Coagulation reactions in citrated milieus were initiated in typical fashion by Ca++ addition or following preincubation with Ca++ prior to tissue factor (Tf) addition in CTI citrate plasma; blood/products stabilized by CTI alone were initiated via Tf addition. Reaction dynamics were analysed using either calibrated automated thrombography (CAT) or thromboelastography (TEG). Platelet aggregation studies compared the reactivity of a panel of agonists. Significant differences were seen in the response of samples exposed to citrate. These results included: CTI plasma and blood displayed a more potent response to Tf when compared to their respective CTI citrate products. Specifically shorter lag phases (~120 s) and higher thrombin levels (1.5–2 fold higher maximum thrombin levels) are observed in CTI plasma with CAT and similarly shorter r (lag) times [(mean ± SD)CTI blood, r = 7.1 ± 0.9 min (n=21, 9 individuals) vs CTI citrate blood, r = 9.1 ± 1.5 min (n=10, 5 individuals)] with TEG. Reconstitution of prechelation Ca++ in CTI citrate plasma or blood prior to Tf addition only partially restored thrombin generation to that of its prechelation product. For example preincubation with Ca++ resulted in altered TEG profiles with prolonged “K” (rate) values (mean ± SD) for CTI citrate blood (7.5 ± 0.6 min (n=5)) compared to CTI blood (3.3 ± 0.5 min (n=5)) from the same individuals. Vitamin K dependent protein conformational transitions in response to chelation/Ca++ reconstitution were important contributors to the differences observed between CTI and citrated blood/plasmas, including the process of protein S polymerization and depolymerization Platelet function studies in citrate containing PRP showed significant enhancement in reactivity toward epinephrine and ristocetin with lesser effects with collagen; in 3 of 4 donors CTI PRP showed no sensitivity to epinephrine. The magnitude of alterations induced by citrate chelation were in the order epinephrine> ristocetin> ADP > collagen. Historically, the regimen of citrate chelation followed by Ca++ addition has proven useful in the interpretation of the integrity of the coagulation system and thereby in clinical diagnosis. However, our results suggest that the procedure of Ca++ chelation/recalcification results in artifactual representations of the dynamics and biology of the blood coagulation process.

Many automated systems for crack analysis have been developed to measure the extent and severity of pavement cracking objectively. However, the accuracy of such an automated crack analysis system has not been satisfactory. This paper presents a crack type index (CTI) that can be easily adopted to determine the crack type objectively as longitudinal, transverse, and alligator cracking. The CTI is based on the spatial distribution of the image tiles rather than image pixels, where a tile is defined as a subimage of a whole digital image. The spatial distribution of image tiles is analyzed vertically and horizontally, with a resulting single index, which can be used to identify a spatial orientation of cracking. To determine the accurate CTI threshold values for longitudinal, transverse, and alligator cracks, 150 pavement images were captured with a digital video camera mounted on a sport-utility vehicle: 50 images for each of three types of cracking. These 150 images were analyzed automatically to compute the CTI values that correlate with crack types. To validate the CTI system, another 150 pavement images were captured. The CTI system identified 150 images as proper crack types with an 86% accuracy for alligator cracking, 92% accuracy for transverse cracking, and 94% accuracy for longitudinal cracking. The CTI system is further validated against images of block cracking and multiple cracks. The validation result against block cracking and multiple cracks indicates that the proposed CTI system in conjunction with UCI is robust and can be extended to identify block cracking and multiple cracks. The CTI method can be used to determine crack types from the digital images automatically without any human intervention.

ObjectiveCavo-tricuspid isthmus atrial flutter (CTI-AFL) is an important arrhythmia to recognise because there is a highly effective and relatively low-risk ablation strategy. However, clinical experience has demonstrated that providers often have difficulty distinguishing AFL from atrial fibrillation.MethodsWe developed a novel ECG-based three-step algorithm to identify CTI-AFL based on established CTI flutter characteristics and verified on consecutive ablation cases of typical flutter, atypical flutter and atrial fibrillation. The algorithm assesses V1/inferior lead F-wave concordance, consistency of P-wave morphology and the presence of isoelectric intervals in the inferior leads. In this observation study, the algorithm was validated on a cohort of 50 second-year medical students. Students were paired in a control and experimental group, and each pair received 10 randomly selected ECGs (from a pool of 50 intracardiac electrogram-proven CTI-AFL and 50 AF or atypical AFL cases). The experimental group received a cover sheet with the CTI algorithm, and the control group received no additional guidance.ResultsThere was a statistically significant difference in the mean number of correctly identified ECGs among the students in the experimental and control groups (8.12 vs 5.68, p<0.001). Students who used the algorithm correctly identified 2.44 more ECGs as being CTI-AFL or not CTI-AFL. Using the electrophysiology study as the gold standard, the algorithm had an accuracy of 81%, sensitivity of 81%, specificity of 82%, positive predictive value of 78% and negative predictive value of 84% in identifying CTI-AFL.ConclusionWe developed a three-step ECG algorithm that provides a simple, sensitive, specific and accurate tool to identify CTI-AFL.

Background: Acute pulmonary thromboembolism (APTE) is a life-threatening condition, often manifesting with chest pain, dyspnea, and increased cardiac biomarkers including cardiac troponin I (CTI) and D-dimer. Therefore, APTE is often misdiagnosed with classical non-ST elevation myocardial infarction (NSTEMI), resulting in unnecessary coronary interventions and a delay of therapy. Objectives: Our aim was to distinguish APTE from NSTEMI based on CTI and D-dimer levels. Methods: Complete clinical and laboratory data sets from APTE patients (n = 123) were compared with matched NSTEMI patients (n = 123) who presented with chest pain. The APTE diagnosis was confirmed by chest tomography, angiography, or radionuclide ventilation-perfusion scan, while NSTEMI was established by clinical symptoms, cardiac biomarkers, and coronary angiography. Clinical characteristics, CTI (initial and peak), and D-dimer levels at presentation were retrospectively analyzed. Results: The clinical characteristics were not different between APTE and NSTEMI patients. However, significantly lower initial CTI (0.2 ± 0.5 vs. 4.4 ± 9.5 ng/ml) and peak CTI (0.7 ± 2.7 vs. 17.1 ± 20.4 ng/ml), but higher initial D-dimer (9.8 ± 9.4 vs. 1.6 ± 3.6 ng/ml), distinguished APTE from NSTEMI. By receiver operating characteristic curve analysis, the cutoff values for initial CTI, peak CTI, and D-dimer were 0.25, 0.98, and 3.18 ng/ml, respectively. Conclusion: Patients with APTE exhibited lower initial and peak CTI but higher D-dimer levels than NSTEMI patients. Assessing cardiac biomarkers is useful for differentiating APTE from NSTEMI. Further large randomized biomarker studies are urgently needed to facilitate a better APTE diagnosis since clinical characteristics are not particularly helpful.

Is China’s textile industry (CTI) still a laboor-intensive one? To answer this question, this study measures the capital-labour intensity and technology intensity of CTI and its sub-sectors during 2006-2018, then applies factor intensity classification and cluster analysis to identify their industrial attributes. The results show that CTI and its sub-sectors are still the labour- and non-technology-intensive. All the indexes of capital-labour intensity and technology intensity of CTI and its sub-sectors are below 100, lower than the average of industry sectors, indicating that they are not separate from the category of labour-intensive industry and still heavily dependent on labour. And cluster analysis verifies the industrial classification results. So CTI still needs to keep on increasing its capital intensity and technology intensity to achieve the goal of industrial transformation and upgrading in the future.

Introduction – The current scientific literature suggests similar or even better catheter contact on caval regions of the cavo-tricuspid isthmus (CTI) compared to the more medial or annular part. Yet CTI ablation can be challenging owing to instability at the inferior vena cava (IVC) edge. No study specifically addressed the issue of catheter-tissue contact on caval/mid/annular regions of the CTI. Methods – Twenty-seven patients (22 men, 67±12 years) underwent typical atrial flutter ablation with a contact force (CF) sensing catheter (Tacticath 75, Abott) and were prospectively included. Operators aimed at optimizing CF for all RF pulses. The product of CF, time (force-time integral; FTI) and delivered power (FTPI) has been proposed as an estimate of lesion size. In a subset of 8 consecutive pts, electrograms (EGM) of all RF lesions were analyzed. Annular CTI was defined as sites showing both atrial and ventricular near-field bipolar EGM. Mid CTI sites had only atrial near field bipolar EGM on both distal and proximal dipoles (or distal only in case of superior-to-inferior approach). Caval sites had near-field bipolar EGM only in distal dipole, while the proximal one was inferiorly located. Results – Complete persistent (at 30 min) CTI block was obtained in all patients. A steerable sheath was used in 12 pts (44%). Procedure duration was 93±30 min, RF delivery time 10±6 min, fluoroscopy time 14±8 min. Mean CF was 15.8±5.9 g. CF was significantly lower (11.1±9.7 g) at the caval CTI than at mid CTI (19.9±11.8 g) and annular CTI (20±12.2 g; p=0.001). CF and FTI were higher during sinus rhythm than during Fl (23.2±15.3 vs 18.5±15.4 g, p=0.04 and 677±432 vs 532±357 gs, p=0.03). Use of a sheath improved mean CF (24.4±12.5 vs 18.4±14.9 g, p=0.01) but this was not significant at caval sites (17.5±11.4 vs 12.6±10.7 g, p=0.31). Conclusion – Applied forces are significantly lower at the IVC edge during CTI ablation. This supports the use of a steerable sheath in challenging cases.

Conspiracy thinking is defined as a form of reasoning about events and situations of personal, social, and historical significance, where “conspiracies” are a dominant factor. This research aims to construct and validate Conspiracy Thinking Inventory (CTI), which purpose is to measure general propensity for conspiracy thinking, rather than beliefs in specific conspiracy theories. Study 1 (N = 356), a preliminary version of CTI consisting of 93 items, was constructed and subsequently shortened to 23 items arranged in 4 facets: Control of Information, Government Malfeasance, Threat towards One’s Own Country, Threat towards Personal Well-being. In Study 2 (N = 180), factor structure and validity of CTI were tested, resulting in a two-factor solution: Conspiracy Thinking Aimed at Health and Well-being (CT), and Attitudes towards the Government Institutions and Representatives (AtGI). The pattern of correlations between CT and relevant constructs confirmed its convergent validity, and CT was also shown to be a good predictor of beliefs in specific conspiracy theories. Previously confirmed convergent and criterion validity and its psychometric characteristics show that CTI may be used as an indicator of conspiracy thinking. Nevertheless, divergent validity has yet to be confirmed by using other constructs (e.g., personality traits). Despite not having been foreseen, extraction of the second factor might be the consequence of using items with predominantly political content. This factor was not correlated with any external criteria which indicate that it does not reflect conspiracy thinking.

ABSTRACT Pseudomonas putida DOT-T1E is a solvent-resistant strain that is able to grow in the presence of high concentrations of toluene. We have cloned and sequenced the cti gene of this strain, which encodes the cis/trans isomerase, termed Cti, that catalyzes the cis-trans isomerization of esterified fatty acids in phospholipids, mainly cis-oleic acid (C16:1,9) and cis-vaccenic acid (C18:1,11), in response to solvents. To determine the importance of this cis/trans isomerase for solvent resistance a Cti-null mutant was generated and characterized. This mutant showed a longer lag phase when grown with toluene in the vapor phase; however, after the lag phase the growth rate of the mutant strain was similar to that of the wild type. The mutant also showed a significantly lower survival rate when shocked with 0.08% (vol/vol) toluene. In contrast to the wild-type strain, which grew in liquid culture medium at temperatures up to 38.5°C, the Cti-null mutant strain grew significantly slower at temperatures above 37°C. An in-frame fusion of the Cti protein with the periplasmic alkaline phosphatase suggests that this constitutively expressed enzyme is located in the periplasm. Primer extension studies confirmed the constitutive expression of Cti. Southern blot analysis of total DNA from various pseudomonads showed that the cti gene is present in all the tested P. putida strains, including non-solvent-resistant ones, and in some other Pseudomonasspecies.

Non-formal education units broadly known by the public are the Community Learning Center (CLC) and Courses and Training Institution (CTI) which have so far been able to improve the quality of education for the community. This study focuses on the description of the capacity mapping management of non-formal education units in improving the quality of education services. The research method used is a qualitative approach with descriptive methods. The research subjects are managers, educators, and students in non-formal education units in Bandung. Data collection techniques used are documentation study, interviews, and focused discussion. This research results in several points, that: (1) description of management of CLC and CTI in Bandung is still not optimal, (2) the map of the quality standards of CLC and CTI in Bandung have not reached the eight National Education Standars yet, (3) expectations of CLC and CTI management are collected and formulated as a conceptual model for the performance of CLC and CTI managers in Bandung.

With the progressive deterioration of cyber threats, collecting cyber threat intelligence (CTI) from open-source threat intelligence publishing platforms (OSTIPs) can help information security personnel grasp public opinions with specific pertinence, handle emergency events, and even confront the advanced persistent threats. However, due to the explosive growth of information shared on multi-type OSTIPs, manually collecting the CTI has had low efficiency. Articles published on the OSTIPs are unstructured, leading to an imperative challenge to automatically gather CTI records only through natural language processing (NLP) methods. To remedy these limitations, this paper proposes an automatic approach to generate the CTI records based on multi-type OSTIPs (GCO), combing the NLP method, machine learning method, and cybersecurity threat intelligence knowledge. The experiment results demonstrate that the proposed GCO outperformed some state-of-the-art approaches on article classification and cybersecurity intelligence details (CSIs) extraction, with accuracy, precision, and recall all over 93%; finally, the generated records in the Neo4j-based CTI database can help reveal malicious threat groups.

Texto completoResumen
The convergence of fifth-generation (5G) communication and the Internet-of-Things (IoT) has dramatically increased the diversity and complexity of the network. This change diversifies the attacker’s attack vectors, increasing the impact and damage of cyber threats. Cyber threat intelligence (CTI) technology is a proof-based security system which responds to these advanced cyber threats proactively by analyzing and sharing security-related data. However, the performance of CTI systems can be significantly compromised by creating and disseminating improper security policies if an attacker intentionally injects malicious data into the system. In this paper, we propose a blockchain-based CTI framework that improves confidence in the source and content of the data and can quickly detect and eliminate inaccurate data for resistance to a Sybil attack. The proposed framework collects CTI by a procedure validated through smart contracts and stores information about the metainformation of data in a blockchain network. The proposed system ensures the validity and reliability of CTI data by ensuring traceability to the data source and proposes a system model that can efficiently operate and manage CTI data in compliance with the de facto standard. We present the simulation results to prove the effectiveness and Sybil-resistance of the proposed framework in terms of reliability and cost to attackers.

Cyberattacks, ever increasing in severity, complexity and frequency are impacting the functioning of citizens, government, and businesses around the world. Protecting valuable intellectual property, business and personal information in digital form against theft, misuse, is an increasingly critical concern for everyone in the present digital era. The financial and reputational loss incurred due to Cyber-attacks motivate organizations to improve defensive measures to protect their organizational networks and information stored. This paper proposes an Cyber threat Intelligence (CTI) collection, log analysis and automated Threat alerting platform capable to analyze and respond to incidents that can lead to cyberattacks. The proposed system makes use of CTI received from Open Source intelligence (OSINT), Elasticsearch and Logstash to analyze, observe and generate alerts for malicious traffic/ activity in organization based on log analysis. At the same time an easy to understand visual representation can be made by the use using Kibana.

The CCD/Transit Instrument (CTI) is a 1.8 m, f/2.2 meridian-pointing telescope located on Kitt Peak. It has no moving parts, but utilizes two RCA charge-coupled devices (CCDs) aligned with columns in the east-west direction and operated in the “time-delay and integrate” (TDI) mode at the apparent sidereal rate to form an image of the sky as it transits (McGraw et al. 1986). The strip is 8.25 arcminutes wide north-south with length determined by the length of the night. Thus, each night the CTI surveys about 15 square degrees of the sky, or about 45 square degrees per year, to a nightly limiting magnitude of mv ≥ 20. One of the two CCDs in the focal plane always observes through a V filter while the other utilizes one of (U), B, R, or I, depending upon the sky brightness. These data are searched to find every detectable object and photometric parameters are calculated for each. These data become part of a Master List which contains the best estimate for each parameter and a History List which maintains a light curve for every detected object. The vital statistics of the project are listed in Table 1.

SummaryThrombin generation monitoring has the potential to be used as a clinical diagnostic tool in the near future. However, robust pre-analytical conditions may be required, and one factor that has been reported is in-vitro contact activation that might influence in-vitro measurements of thrombin generation and thereby act as an unpredictable pre-analytical variable. The aim of the current study was to investigate the influence of contact activation and the necessity of corn trypsin inhibitor (CTI) to abolish contact activation in thrombin generation measurements at low tissue factor (TF) concentrations. Thrombin generation was performed using the calibrated automated thrombinoscopy (CAT), thereby determining the endogenous thrombin potential (ETP), peak height, and the lag time, in plasma obtained from healthy volunteers. Addition of CTI after plasma preparation had no significant influence on thrombin generation triggered with 0.5 pM TF or higher, as demonstrated by unaltered ETP and lag time values between analyses with and without CTI. Addition of CTI before blood collection reduced thrombin generation triggered with 0.5 pM TF: both the ETP and peak height were significantly reduced compared to no CTI addition. In contrast, thrombin generation remained unaltered at a 1 pM TF trigger or above. This study demonstrates that addition of CTI after plasma separation is not necessary when triggering with TF concentrations of 0.5 pM and higher. Furthermore, it was demonstrated that it is not needed to pre-fill blood collecting tubes with CTI when measuring thrombin generation at TF concentrations of ≥1 pM.

Encaminhando-me na perspectiva da fenomenologia, minha proposta é apreender, através dos depoimentos das enfermeiras que trabalham no CTI, os significados que as mesmas atribuem a essa vivência. Ao refletir sobre tais significados, aliando-os à minha experiência profissional, busco compreender o fenômeno ser enfermeira no CTI. Coletei depoimentos escritos das enfermeiras que atuavam no centro de terapia intensiva da Unidade de Emergência do Hospital das Clínicas da Faculdade de Medicina - Ribeirão Preto - USP, tendo como questão orientadora: o que significa para você ser enfermeira no CTI. Da análise desses depoimentos (MARTINS, 1992), emergiram as categorias temáticas, revelando que ser enfermeira no CTI é cuidar diretamente dos pacientes, é ter capacidade administrativa, é conviver com máquinas e equipamentos, exige muitos requisitos e o domínio de conhecimentos específicos, é desempenhar um trabalho importante, de responsabilidade e gratificante, bem como, conviver com situações limitantes e de estresse. A partir de uma reflexão compreensiva do modo de ser da enfermeira desse CTI, pretendo contribuir para busca de novas perspectivas do fazer, ampliando seu horizonte de possibilidades.

O objetivo do presente trabalho é compreender a presença do tema da Ciência, Tecnologia e Inovação (CTI) na agenda internacional do Brasil no período de 1990 a 2010 à luz das diretrizes de Política Externa Brasileira e das Políticas de Ciência, Tecnologia e Inovação (PCTIs) dos governos abarcados. A hipótese adotada pelo trabalho é a de que se pode notar uma abordagem diferente ao tema da CTI na agenda internacional do Brasil conforme as diferentes orientações político-econômicas dos governos em análise. Os resultados da pesquisa demonstram que à luz das PCTIs a abordagem para a CTI na agenda internacional do Brasil teve continuidade mesmo em governos situados em espectros políticos diferentes. Não obstante, à luz das diretrizes de política externa se observam variações entre os governos da década de 1990 e os governos da década de 2000. Para os anos 2000, foi percebida uma maior atividade internacional brasileira em matéria de CTI na medida em que ocorreram mudanças no perfil internacional do Brasil (com maior proatividade e diversificação de sua atuação) decorrentes de uma nova orientação política-econômica nos anos 2000. Ainda que não seja possível identificar uma priorização do tema da CTI se comparado a outras pautas da agenda internacional do país, o Brasil, de fato, mudou sua atuação internacional em matéria de CTI nos anos 2000.

Background: Latin America, and Chile in particular, has a rich tradition of community mental health services and programs. However, in vivo community-based psychosocial interventions, especially those with a recovery-oriented approach, remain scarce in the region. Between 2014 and 2015, a Critical Time Intervention-Task Shifting project (CTI-TS) was implemented in Santiago, Chile, as part of a larger pilot randomized control trial. CTI is a time-limited intervention delivered at a critical-time to users, is organized by phases, focuses on specific objectives and decreases in intensity over time. CTI-TS, which combines both the task-shifting strategy and the use of peers, introduces a novel approach to community mental health care that has not yet been tried in Chile. Aims: We aim to evaluate the feasibility, acceptability and applicability of such a community-based psychosocial intervention in urban settings in Latin America – specifically, in Santiago (Chile) from a user perspective. Method: We analyzed 15 in-depth interviews ( n = 15) with service users who participated in the intervention about their perceptions and experiences with CTI-TS through thematic analysis. Results: Three themes were revealed. The first was related to the structural characteristics of CTI-TS, especially regarding the timing, duration and phasic nature of the intervention. The second pertained to the acceptability of the in vivo community-based approach. The third theme dealt with the task-shifting aspect, that is, users’ perceptions of the peer support workers and the community mental health workers. Conclusions: CTI-TS was generally acceptable in this Latin American context. Users’ perspectives pointed to the need to make adjustments to some of the structural characteristics of the CTI model and to combine this type of intervention with others that can address stigma. Thus, future adaptations of CTI-TS or similar psychosocial interventions in Latin American contexts are feasible and can enhance community mental health in the region.

A CCD/Transit Instrument (CTI) has produced relative astrometry with standard errors less than 2.6% of a 1.55 arcsecond pixel for stars with V ≤ 17. Additional astrometric studies with existing data are required to better understand the ultimate contribution these devices can make to our science.The CTI is presently dismantled, awaiting a move to a new site. We briefly discuss the potential astrometric scientific returns from the exisiting data set, from a refurbished CTI, and from a similar device emplaced on the Moon.

Imaging of the electrical conductivity distribution inside the human body has been investigated for numerous clinical applications. The conductivity tensors of biological tissue have been obtained from water diffusion tensors by applying several models, which may not cover the entire phenomenon. Recently, a new conductivity tensor imaging (CTI) method was developed through a combination of B1 mapping, and multi-b diffusion weighted imaging. In this study, we compared the most recent CTI method with the four existing models of conductivity tensors reconstruction. Two conductivity phantoms were designed to evaluate the accuracy of the models. Applied to five human brains, the conductivity tensors using the four existing models and CTI were imaged and compared with the values from the literature. The conductivity image of the phantoms by the CTI method showed relative errors between 1.10% and 5.26%. The images by the four models using DTI could not measure the effects of different ion concentrations subsequently due to prior information of the mean conductivity values. The conductivity tensor images obtained from five human brains through the CTI method were comparable to previously reported literature values. The images by the four methods using DTI were highly correlated with the diffusion tensor images, showing a coefficient of determination (R2) value of 0.65 to 1.00. However, the images by the CTI method were less correlated with the diffusion tensor images and exhibited an averaged R2 value of 0.51. The CTI method could handle the effects of different ion concentrations as well as mobilities and extracellular volume fractions by collecting and processing additional B1 map data. It is necessary to select an application-specific model taking into account the pros and cons of each model. Future studies are essential to confirm the usefulness of these conductivity tensor imaging methods in clinical applications, such as tumor characterization, EEG source imaging, and treatment planning for electrical stimulation.

Abstract In the previous ASH Meetings, we have reported that thrombin/antithrombin III complex in association with high density lipoprotein directly stimulated PPF of human or murine megakaryocytes through Rho pathway. Recently, we found that CTI also induced PPF of murine megakaryocytes and PP of MEGs in vitro. In this study, we investigated the signal transduction pathways of cytoskeltal reorganization responsible for PP in MEGs after the stimulation with CTI. Murine megakaryocytes were incubated for 48 hrs in serum free condition on CTI dishes. PPF of murine megakayocytes were significantly increased (collagen (−): 25.5±5.0%, collagen (+): 36.0±1.0%, mean±SD, P<0.05). In the culture of murine megakaryocytes on CTI dishes with phosphatidylinositol 3-kinase (PI3K) inhibitor (LY294002) or Src family kinase inhibitor (PP1, SU6656), PPFs of murine megakayocytes were inhibited (LY294002:0μM:31.7±1.0%,1μM:25.8±2.2%, 10μM:28.1±8.2%,100nM:26.1±5.1% (p<0.05), PP1:0nM:32.4±1.0%,0.2μM:24.5 ±5.2%,2μM:21.3±2.5%,20 μM:15.9±5.7% (p<0.01), SU6656: 0nM: 32.2±1.0%, 2.5μM:30.0±1.3%,25μM:15.5±4.5% (p<0.01) ). These results suggest that PPF of megakaryocytes was induced by CTI through Rac activation pathway, based on that Rac is activated by two pathways including PI3K and Src family kinese. As we could not obtain enough murine megakaryocytes, MEGs (cell line) were used to determine whether or not the Rac is activated after the stimulation by CTI. PP of MEGs was significantly increased after the incubation of MEGs on the CTI dishes (collagen (−): 16.0±5.0%, collagen (+): 58.3±7.2%, (p<0.01)) (shown in Figure1). In the culture of MEGs on CTI dishes with LY294002, PP1 or SU6656, PPs of MEGs were significantly inhibited(0nM:54.9± 1.0%, LY294002:0.5μM:48.3±7.2%, PP1:20μM:47.9±1.1%, SU6656:5μM:44.9±6.7%,(p<0.05) ). These results were similar to those of murine megakaryocytes. Therefore, activation of Rac was investigated using MEGs. MEGs, which were incubated in the serum free conditon on the CTI dishes at 0, 60, 90, 120, 150 and 180 min. Activated Rac in the whole lysate were co-precipitated with p21-activated kinase-p21Binding domain (PAK-PBD) beads. The amount of activated Rac was detected by a Western blot using anti Rac specific antibody. Rac was activated at 60min and tapered at 120min after incubation on CTI dishes, shown in Figure 2. Phospholylation of cofilin (Ser3) was also evaluated by a Western blot using anti phospholylated cofilin (Ser3) antibody. Phospholylated cofilin (Ser3) expression began to be detected at 60 min, peaked at 120min, and tapered at 180 min. These data suggests that integrin alpha2beta1 on megakaryocytes was stimulated by CTI, followed by the activation of Rac through PI3K and Src family kinase, and by phospholylation of cofilin (Ser3). These pathways may play an important role in platelet production in vitro. Figure 1. MEGs after the stimulation with collagen type I Figure 1.

Reproductive tract infection (RTIs)/sexually transmitted infections (STIs) are recognized as a major public health problem, particularly due to their relationship with HIV infection. Early detection and treatment ofChlamydia trachomatisinfection (CTI) among HIV-infected and HIV-uninfected women may impact heterosexual HIV transmission. A total of 120 participants were enrolled: 30 HIV seropositive women with symptoms of RTIs, 30 HIV seropositive women without symptoms of RTIs, 30 HIV seronegative women with symptoms of RTIs, and 30 HIV seronegative women without symptoms of RTIs. One endocervical swab was collected from all participants and CTI was detected by real-time PCR (COBAS TaqMan CT Test, v2.0). CTI was detected in 4 (6.67%) HIV-infected women and in 1 (1.67%) HIV-uninfected woman (OR 4.214; 95% CI 0.457–38.865). Vaginal discharge was present in almost half of HIV-infected and HIV-uninfected women; lower abdominal pain was present in 11 (18.3%) of HIV-infected and in 9 (15%) of HIV-uninfected women. This study showed that CTI is more prevalent among HIV-infected females as compared to HIV-uninfected females. As the use of real-time PCR is not feasible in most hospitals, efforts should be made to develop a simple, sensitive, and specific test to identify women with CTI for prevention of sequelae and HIV transmission.

Texto completoResumen
Se pretende contribuir a la reflexión sobre cambios y continuidades de las políticas de Ciencia, Tecnología e Innovación en Latinoamérica, buscando entender los efectos de la introducción, en las prácticas políticas recientes, de modelos que vinculan la CTI con los problemas de inclusión y desarrollo social. Para ello, se analizan comparativamente las experiencias de generación de planes estratégicos de CTI de Brasil y Uruguay en el periodo 2003-2015. Luego de presentar las principales concepciones teóricas sobre políticas CTI, se analizan las formas en que se aborda el tema de la inclusión y el desarrollo social en los estudios, propuestas, planes y estrategias nacionales de CTI en cada país. Se analizan, después, los instrumentos de política y presupuestos implementados en el periodo. Finalmente, se comparan ambos procesos, destacando las similitudes y diferencias detectadas. Se concluye que el contexto político favorable para la incorporación del tema de CTI para la inclusión y el desarrollo social, propiciado por la asunción de gobiernos progresistas y la incorporación en sus agendas de dichos temas como fundamentales, no fue suficiente para consolidar una política efectiva y duradera en la materia, más allá de su incorporación en el discurso, en documentos oficiales y en planes de ambos gobiernos.

Texto completoResumen
Ablation of cavotricuspid isthmus (CTI) is the gold standard method in the treatment of isthmus dependent atrial flutter (AFl). Venous access was obtained usually via right or left femoral veins. In rare cases of obstruction of iliofemoral veins, ablation of CTI can be performed only through the superior approach. We present a 74-year-old woman of typical AFl and dilated cardiomyopathy that was ablated through the right jugular vein because of obstruction of the left and the right iliac veins. This is the first report of successful ablation of CTI in a patient with dilated cardiomyopathy via superior approach.

Texto completoResumen
Cyber threat is a major issue that has been terrorizing the computing work. A typical cyber-physical system is crucial in ensuring a safe and secure architecture of a sustainable computing ecosystem. Cyber Threat Intelligence (CTI) is a new methodology that is used to address some of the existing cyber threats and ensure a more secure environment for communication. Data credibility and reliability plays a vital role in increasing the potential of a typical CTI and the data collected for this purpose is said to be highly reliable. In this paper, we have introduced a CTI system using blockchain to tackle the issues of sustainability, scalability, privacy and reliability. This novel approach is capable of measuring organizations contributions, reducing network load, creating a reliable dataset and collecting CTI data with multiple feeds. We have testing various parameters to determine the efficiency of the proposed methodology. Experimental results show that when compared to other methodologies, we can save upto 20% of storage space using the proposed methodology.
