Study on Steroid Utilization Patterns in General Medicine Department

Background: Corticosteroids are of great value in treating a wide spectrum of inflammatory conditions as they provide rapid symptomatic relief, especially in the short term. These highly efficacious drugs are mostly used for the treatment of various autoimmune, respiratory, and dermatological conditions. The frequent use of steroids for their palliative effects often leads to its misuse in medicine practice. Periodic monitoring of the drug utilization pattern is one of the methods to analyse the rationality of drug use and has been an effective tool to constitute guidelines for improving the utilization pattern. Aim and objectives: to study the prescribing patterns of steroids in general medicine department, to study the prescribing and administration related factors. Methodology: A prospective observational study was carried out in 324 In-patients from the general medicine department of the hospital during eight months period and subjected to statistical analysis. Results: Out of 324 patients, 207 (63.9%) were males, and 117 (36.1%) were females. More than half of the study population (53.1 %) belonged to the elderly age group of 51-70 years. Social habits of the patients revealed that 105 patients were smokers, 149 patients consumed alcohol. 154 (47.5%) of the patients were teetotallers and non-smokers. Almost 38.8% of reasons were related to respiratory tract infection for which steroid prescription was found to be common. Out of 324 cases common morbidities were COPD (34.9%), asthma(17.0%), broncho pneumonia (16.0%), other pulmonary diseases (8.6%). Other reasons included severe allergic reactions (7.7%), allergic conditions (7.4%), tuberculosis (4.9), dermatological Diseases (2.5%) and septic shock (0.9%), etc. budesonide was the most prescribed steroidal drug for 214 (66%) patients followed by hydrocortisone 56 (17.30%), prednisolone 29 (9%) and so on. Conclusion: It may be concluded that clinical pharmacist can play an important role in the prescription audit and safety assessment of steroid medications in hospital settings, including corticosteroids. The commonly used corticosteroids were budesonide and frequently used in respiratory diseases like COPD and Asthma.
UAV Transmission Line Inspection Object Recognition based on Mask R-CNN

Currently, unmanned aerial vehicles (UAV) are applied to routine inspection tasks of power transmission devices. Deep-learning algorithm and machine vision have attracted much attention in the field of the UAV’s autonomous control as it’s an effective way to improve the efficiency of inspection. Considering the differences between the distant and close view, this paper adopts Mask R-CNN to detect various components of power transmission devices but use the methods such as processing of the edge, hole filling and Hough Transform identify the wires in distant. Some major components, such as pole, truss, cross arm, insulator string and so on, can be 100% recognized. This proposed model shows the characteristics of high recognition speed and high accuracy, which can assist UAV to inspect well.
Employment after prison: Navigating conditions of precarity and stigma

In an effort to extend understanding of the employment concerns faced by former prisoners released into the community, we draw from the voices of 24 individuals released from federal prison in Canada. We explore how the stigma imposed on individuals with prior experiences of incarceration interacts with the employment programming government and community-based agencies offer; particularly within the current climate of precarious employment. Findings evidence that participants, too often, attain employment involving manual labour and report experiencing low-wage and non-gratifying jobs, despite participation in pre-employment programming, which drives their re-evaluation and re-creation of career aspirations. We show how the conditions underpinning the movement toward employment for former prisoners can encourage the potential exploitation of their labour within both formal and informal job markets.
Investigating the Effect of Gamification Mechanics on Customer Loyalty in Online Stores

This study examines how gamification mechanics could be used in online retailers' loyalty programs. In other words, this article attempts to create a conceptual model for the relationship between gamification mechanics and customer loyalty elements. We used a field study to conduct our research. In order to validate the survey, 450 customers from one of the greatest online stores in Iran were questioned. The results of this survey were used to validate our 11 phrases on the relationship between gamification mechanics and customer loyalty. The results were analyzed using confirmatory factor analysis, path analysis, and model fitness tests in structural equations modeled in the Lisrel software. According to the research findings, the relationship between variables and the proposed conceptual model was confirmed. Based on the performed analysis, all 11 phrases were verified.
Usability testing electronic rubric of performance assessment

Integrating technology in the assessment process facilitates the overall education process, for teachers, students, and educational institutions. Online Evaluation System is an e- learning application in the context of the “Learning Evaluation System” which is designed to facilitate the evaluation process. In creating a digital assessment tool, one needs to pay attention to the usability aspect as the key to success and as a user acceptance requirement for the application. In this research, researcher tested the usability performance assessment in the form of an electronic rubric to assess learning. Usability testing aims to determine whether an application is in accordance with the user needs or not. Usability testing uses an evaluation sheet in the form of a questionnaire, namely Use Questionnaire, a tool that can be used in the preparation of the questions that will be made in the form of a questionnaire. Testing was done by observing the user; how they used the application. The components tested consisted of components of usefulness, satisfaction, ease of use and ease of learning. The application tested was SmartRubric, an assessment application designed to facilitate the workload of teachers in carrying out the evaluation process. The test results show that respondents generally strongly agree with the usability aspect of SmartRubric application software. The research concludes that electronic rubric is a resource that facilitates assessment for students as participants in the assessment process. Students tend to be satisfied with the use of electronic rubrics in assessment.
Acoustic Feedback Suppression for Multi-Microphone Hearing Devices Using a Soft-Constrained Null-Steering Beamformer

Acoustic feedback occurs in hearing aids due to the coupling between the hearing aid loudspeaker and microphone(s). In order to reduce the acoustic feedback, adaptive filters are commonly used to estimate the feedback contribution in the microphone(s). While theoretically allowing for perfect feedback cancellation, in practice the adaptive filter typically converges to a biased optimal solution due to the closed-loop acoustical system of the hearing aid. Previously it has therefore been proposed to suppress the acoustic feedback contribution for an earpiece with multiple integrated microphones and loudspeakers using a fixed null-steering beamformer and hence avoiding a biased adaption. While previous null-steering beamforming approaches aimed at perfect preservation of the incoming signal using its relative transfer function (RTF), in this article we propose to use a soft constraint that allows to trade off between incoming signal preservation and feedback suppression. We formulate the computation of the beamformer coefficients both as a least-squares optimization procedure, aiming to minimize the residual feedback power, and as a min-max optimization procedure, aiming to directly maximize the maximum stable gain of the hearing aid. Experimental evaluations were performed using measured acoustic feedback paths from a custom earpiece with two microphones in the vent and a third microphone in the concha. Results show that the proposed fixed null-steering beamformer using the RTF-based soft constraint provides a reduction of the acoustic feedback by 7–8 dB compared to the previously proposed RTF-based hard constraint while limiting the distortions of the incoming signal in the beamformer output.
Deeper learning as integrated knowledge and fascination for Science

ABSTRACT For scholars and policy-makers alike, deeper learning has been a promising paradigm for fostering students’ interest in and mastery of science, technology, engineering, and mathematics (STEM). Deeper learning is assumed to result in a more thorough understanding of a subject that endures the test of time. To reach this level, a fascination with the subject matter is thought to be a critical motivational element. The focus of our study was to measure the two core consequences of deeper learning: the extent of knowledge integration and the level of fascination with the subject matter (in this case, science and technology). Using a sample of sixth graders from Greece, Finland, France, and Portugal (N = 1,261), we explored the measurement properties of the two newly developed instruments. Both of our deeper learning assessment tools showed satisfactory measurement properties (i.e. fit indices and reliabilities). More importantly, both tools were able to cover a broad range of integrated knowledge and fascination, and thus, they can be used to differentiate between sixth-grade European students with low to high levels of fascination and knowledge. These properties of our assessment tools and their out-of-the-box availability will help foster more empirical research and the development of the deeper learning paradigm.
Vowel dynamics in the acquisition of L2 English – an acoustic study of L1 Polish learners

ABSTRACT This article presents an acoustic study of the acquisition of vowel formant dynamics in L2 (Southern British) English by Polish learners at two levels of proficiency, along with baseline data from L1 English and L1 Polish. Results from our experiment suggest that the acquisition of English vowels by Polish learners entails a temporal reorganization such that vocalic targets in English are housed later in a vowel’s duration than they are in Polish or Polish-accented English. This leads to an increase in the degree of formant movement through the 20%–40% portion of vowel duration with increased English proficiency. Implications of these findings for cross-language phonetic similarity, a crucial concept for current theoretical models of L2 speech, are also discussed.

We compare pulse-switching operations in MZI- and ring-switches both experimentally and based on large-signal circuit simulations. With a modiﬁcation in switch design and with optimization of phase modulator lengths, we show high-speed switches with potential for an over 3 dB improvement in energy consumption.
Possible role of warming on Indian summer monsoon precipitation over the north-central Indian subcontinent

ABSTRACT Broad disagreement between modelled and observed trends of Indian summer monsoon (ISM) over the north-central part of the Indian subcontinent (NCI) implies a gap in understanding of the relationship between the forcing factors and monsoonal precipitation. Although the strength of the land–sea thermal gradient (LSG) is believed to dictate monsoon intensity, its state and fate under continuous warming over the Bay of Bengal (BoB) and part of the NCI (23–28°N, 80–95°E) are less explored. Precipitation (1901–2017) and temperature data (1948–2017) at different vertical heights are used to understand the impact of warming in the ISM. In NCI, surface air temperature increased by 0.1–0.2°C decade−1, comparable to the global warming rate. The ISM precipitation prominently weakened and seasonality reduced after 1950, which is caused by a decrease in the LSG at the depth of the troposphere. Warming-induced increase in local convection over the BoB further reduced ISM precipitation over NCI.
Performance Analysis and Resource Allocation for Relaying in Cognitive Radio and Device-to-Device Communications

Cognitive radio and device-to-device (D2D) communication are promising technologies in fifth generation (5G) wireless communications to enhance spectral efficiency. In cognitive radio, unlicensed users, called secondary users, opportunistically utilize the spectrum of licensed users, called primary users. In D2D communication, two wireless devices communicate with each other directly. To improve reliability and data rate, various relaying techniques have been applied in cognitive radio and D2D communication. The dissertation consists of three main results. First, we investigate the underlay cognitive radio network with cascaded Rayleigh fading channels where secondary users transmit signal using multi-hop relaying. We analyze the outage probability of the secondary network for perfect channel state information (CSI) and imperfect CSI cases. For both perfect and imperfect CSI cases, we derive the exact outage probability of the secondary network with the maximum transmit power constraint in analytic form and the approximate outage probability of the secondary network without the maximum transmit power constraint in closed form. By using the outage probability, we propose the secondary user selection scheme to minimize the outage probability.
Illuminating Diversity Practices in Malaysian Higher Education Institutions

This study investigated the current level of awareness on diversity-related issues and its relations to diversity climate and global-mindedness of students and lecturers in Malaysian Higher Education Institutions. A total of 615 students from various private and public universities, polytechnics and community colleges participated in the survey. They comprised Chinese, Malay, Indians and others. The Diversity Climate Survey and the Global Mindedness Scale by J. E. Hett were used and the analysis was conducted using ANOVA and Bivariate Correlational Analysis. The construct reliability for both tests ranged between . 86 and . 90 and . 58 and . 76 for Diversity Climate and Global Mindedness respectively. Results indicated that differences were found in the perceptions of diversity climate and levels of global mindedness in terms of gender, ethnicity and types of institution. Overall, the Malaysian Higher Education Institutions have reported a moderate climate in diversity and a low level of global-mindedness. In terms of ethnicity, there was a significant difference in students’ perception of Diversity Climate and Global Mindedness. A broader scope of knowledge and awareness on learner diversity is needed to ensure sustainable development of our higher education institutions.
Locating and understanding the largest gender differences in pathways to science degrees

Correspondence Eben B. Witherspoon, Learning Research and Development Center, University of Pittsburgh, 3939 O’Hara St., Pittsburgh, PA 15217. Email: eben.witherspoon@pitt.edu Abstract While gender parity has been achieved in overall science degree earning, large gaps still exist within many science disciplines. Further, studies addressing gender inequity in science often ignore a large source of undergraduate science degree earners: those who enroll in science courses intending to pursue careers in health or medicine. This study examines pathways toward or away from science degrees in N = 4,345 men and women enrolled in early science courses at a large undergraduate research university. Importantly, to understand shifts in students’ academic intentions and how pathways to science may be differential by gender, this study analyzed students’ incoming major and career intentions, estimates of incoming academic abilities, and relative performance in science and various non‐science courses. Results show that while men and women initially intending to pursue a science major graduate with science degrees in equal numbers, the plurality of science degree earners are students entering college intending health or medical careers. Further, from those subgroups, a significantly larger proportion of men end up in science, while a significantly larger proportion of women end up outside of STEM completely. Understanding disciplinary differences in gender barriers to science participation can help inform interventions that specifically target those populations.
The Evaluation of Tolvaptan Therapy and Long-Term Prognosis in Hepatocellular Carcinoma with Refractory Ascites

We investigated Tolvaptan efficacy and long-term prognosis with focus on nutrition in 20 patients with refractory hepatic ascites in hepatocellular carcinoma (HCC). Bloating improved in 55% of patients, as determined using a Japanese version of the Support Team Assessment Schedule. Nutritional status improved with Tolvaptan treatment, based on the Controlling Nutritional Status score and Onodera’s prognostic nutritional index. Long-term prognosis was better in responders than in non-responders (mean survival time: 308 days vs. 97 days, p = 0.031). Tolvaptan was even effective in many patients with HCC, with additional improvement in long-term prognosis expected with improvement in the nutritional status.
The Efficacy of Logbook in Clinical Wards from the Viewpoints of Nursing Faculty Members and Students

Introduction: promoting clinical training of nursing students is an important feature that needs to constant assessment, in this regards, log book consider as an effective clinical assessment method. The aim of this study was to determine the efficacy of logbook in clinical wards from the viewpoints of nursing faculty members and students of Zahedan Nursing and Midwifery School. Methods: In this cross-sectional study, 100 students and 24 faculty members of Zahedan Nursing and Midwifery School were studied in 1396. The data were gathered via a researcher-made questionnaire composed of two sections including demographic characteristics and questions related to the logbook contains four areas of quality, necessity, outcomes and how to complete the logbook with 42 items and an open-ended question. Content validity approved by faculty members and reliability was confirmed by test-retest (0.80). Data were analyzed by descriptive and analytical statistics (independent t-test) using SPSS software. Findings: 87.5% of faculties and 44% of the students believed that using logbook was necessary in the practical courses. More than 60% of faculties and students believed that logbook activities did not fit students' needs. In addition, 66.7% of faculties and 59% of students filled out the logbook daily. The average total score of the view of faculties and students from the logbook were 52.58±9.18 and 43.22±9.80, respectively. There was a significant difference between the mean scores of the two groups (P<0.001). Conclusion: Based on findings, faculties' viewpoints regarding the logbook was more positive than the students but since logbook has to meet student learning needs, revising the content of logbook continually is necessary.

Genetic ablation of SOD1G37R selectively from corticofugal projection neurons protects corticospinal neurons from degeneration without affecting ALS onset and progression

While clinical evidence of combined degeneration of the bulbar and spinal motor neurons (MN) together with the corticospinal neurons (CSN) is required to diagnose Amyotrophic Lateral Sclerosis (ALS), preclinical studies have mostly concentrated on MN, leaving aside the CSN and their contribution to ALS onset and progression. Recent studies carried on ALS patients suggest that the disease may initiate in the motor cortex and spread to its projection targets, along the corticofugal axonal projections (including CSN), either via altered neuronal excitability and subsequent excitotoxicity, or via prion-like propagation of misfolded proteins. We recently provided first experimental arguments in favour of the corticofugal hypothesis of ALS, demonstrating that CSN and other subcerebral projection neurons were toxic in a context of ALS. Here, we aimed to determine how CSN may be detrimental to their downstream targets, and what governs their degeneration. To answer these questions, we took advantage of the FloxedSOD1G37R mouse model of ALS that allows genetic ablation of the mutant transgene in selected cells upon Cre-mediated recombination, and crossed it to the CrymCreERT2 mouse line that we purposely designed to genetically target CSN and other corticofugal projection neurons (CFuPN) populations. We demonstrate that excision of the mutant SOD1G37R transgene from the CSN is sufficient to prevent their death, suggesting that CSN degeneration mostly relies on cell-intrinsic mechanisms. However, genetic ablation of SOD1G37R transgene from the corticofugal neurons had no effect on disease onset and survival. The data thus indicate that the toxicity of CFuPN in the context of ALS, and corticofugal propagation of the disease, are not mediated by the presence of misfolded mutant proteins, but more likely by other aspects of the cortical pathology, possibly hyperexcitability.
