PREVALENCE OF VARIOUS PREMENSTRUAL SYMPTOMS AMONG HEALTHY WOMEN

The menstrual cycle is a normal physiological process unique to females, the experience of which results from a complex interaction of biological and behavioral factors. The distressing symptoms occur cyclically in women prior to menstruation has been recognized for centuries by clinicians. The various premenstrual physical, emotional or behavioral changes experienced by many women may reach such levels of severity that they may have substantial social impact upon the women herself, or associates, and her work. The sample consists of 100 medical students and 50 staff nurses selected randomly using random tables from the attendance registers of staff nurses in SVRRGGH & Women's hostel of S. V. Medical College. In the present study fifty women reported at least one affective symptom and they are followed up prospectively by daily symptom recordings for three menstrual cycles.
Investigating the Accuracy of One‐Dimensional Volcanic Plume Models using Laboratory Experiments and Field Data

During volcanic eruptions, model predictions of plume height are limited by the accuracy of entrainment coefficients used in many plume models. Typically, two parameters are used, α and β, which relate the entrained air speed to the jet speed in the axial and cross‐flow directions, respectively. To improve estimates of these parameters, wind tunnel experiments have been conducted for a range of cross‐wind velocities and turbulence conditions. Measurements are compared directly to computations from the 1‐D plume model, Plumeria, in the near‐field, bending region of the jet. Entrainment coefficients are determined through regression analysis, demonstrating optimal combinations of effective α and β values. For turbulent conditions, all wind speeds overlapped at a single combination, α = 0.06 and β=0.46, each of which are slightly reduced from standard values. Refined coefficients were used to model plume heights for 20 historical eruptions. Model accuracy improves modestly in most cases, agreeing to within 3 km with observed plume heights. For weak eruptions, uncertainty in field measurements can outweigh the effects of these refinements, illustrating the challenge of applying plume models in practice.
Early contractor involvement (ECI): ways to do it in public projects

Early contractor involvement (ECI) faces many barriers because it differs from traditional business practices. Public owners, especially, face a major challenge because they must comply with international and national legislation. The purpose of this paper is to develop a framework that illustrates the various approaches that public project owners can take to implement ECI. ,In addition to a literature review, three groups of case studies were carried out. The case studies were based on 54 semi-structured in-depth interviews with key personnel from 21 Norwegian public projects and document study. ,In all, 25 approaches to ECI were identified during the research. Twelve of these were used in the cases studied. ,There are several approaches to ECI that are suitable for public owners. However, the contractor’s contribution depends on which approach is implemented and how it is implemented. ,As original contribution, this study presents a novel framework that defines options for implementing ECI in public projects. Furthermore, this paper provides insights on how ECI can be implemented in public projects based on Norwegian experiences. Although the empirical data of the study is limited to Norwegian public projects, this study contributes to knowledge about how to implement ECI internationally.
Slow Thinking Enables Task-Uncertain Lifelong and Sequential Few-Shot Learning

Lifelong machine learning focuses on adapting to novel tasks without forgetting the old tasks, whereas few-shot learning strives to learn a single task given a small amount of data. These two diﬀerent research areas are crucial for artiﬁcial general intelligence, however, their existing studies have somehow assumed some impractical settings when training the models. For lifelong learning, the nature (or the quantity) of incoming tasks during inference time is assumed to be known at training time. As for few-shot learning, it is commonly assumed that a large number of tasks is available during training. Humans, on the other hand, can perform these learning tasks without regard to the aforementioned assumptions. Inspired by how the human brain works, we propose a novel model, called the Slow Thinking to Learn (STL), that makes sophisticated (and slightly slower) predictions by iteratively considering interactions between current and previously seen tasks at runtime. Having conducted experiments, the results empirically demonstrate the eﬀectiveness of STL for more realistic lifelong and few-shot learning settings.
Performance Model for Advanced Neighbor Discovery Process in Bluetooth Low Energy 5.0-Enabled Internet of Things Networks

The neighbor discovery process (NDP) plays a key role in Bluetooth low energy (BLE)-enabled applications. However, when a massive number of BLE devices are involved in the NDP, signal collisions become severer, which degrade the NDP performance seriously. To solve the problem, BLE 5.0 specifies some extended features such as advanced NDP (A-NDP). The previous works on the performance models for the NDP have focused on the basic NDP (B-NDP). Though some works considered the performance evaluations on A-NDP, they have done on simulations or testbed-based experiments. Likewise, so far, the performance analysis for A-NDP has been insufficient. In this article, we propose an analytical model to evaluate A-NDP performances, such as the signal collision probability, the discovery delay, the energy consumption, and so on. With the proposed analysis model, the performances of A-NDP are analyzed from the viewpoint of various operational environments for BLE-enabled Internet-of-Things services, and compared to those of B-NDP with extended features of Bluetooth 5.0. Besides, it showed that A-NDP is not always better than B-NDP, and we discuss the operational conditions where A-NDP or B-NDP operate effectively, respectively.

AIDS is prevalent in the men sleeping with men (MSM) community. There is lack of studies evaluating the quality and quantity of communication between MSM and medical professionals, which can be a catalyst to help reduce HIV/AIDS within this community. The aim of this quantitative study was to evaluate the relationship between quantity and quality of medical professionals’ communication and regular HIV screening and testing, as well as modifying high-risk behaviors attributing to HIV/AIDS MSM behaviors, controlled for race/ethnicity, educational level, and income. Universal precautions theory and health belief model were the theoretical framework of this study. A total of 126 MSM were evaluated via survey research. Chi-square analysis revealed that MSM who have ever visited a medical professional about HIV/AIDS were tested in significantly higher frequency compared with those that did not visit medical professional for this reason (51.5% vs. 18.5%, respectively, p < .001). Also, significantly more participants changed their sexual behavior during the last 5 years and considered that the approach of the medical professional contributed in this change, compared with those who changed their sexual behavior but did not consider this approach helpful (73.7% vs. 26.7%, p < .001). This research can provide positive social change to the MSM community as well as medical professionals, by encouraging MSM to seek more information pertaining to safe sexual health practices, prevention, and awareness.

Plasma-beta Modulated Characteristics of Magnetohydrodynamic Waves around the Heliospheric Current Sheet

The magnetohydrodynamics (MHD) wave modes in the heliospheric current sheet (HCS) and the associated heliospheric plasma sheet (HPS) have not been comprehensively investigated in the literature. Based on a frequency-related identification approach, the properties of MHD waves are investigated during 154 HCS crossings observed by the Wind spacecraft from 1995 to 2013. Statistically, the incidence of MHD waves around HCS/HPS is found to be modulated by the plasma β within the HPS: (1) β > 5, both Alfvén and slow waves obviously decay within the HPS, with the occurrence rate (OR) decreasing from 60% and 20% in the upstream/downstream to 41% and 14% in the HPS vicinity, respectively; (2) 1 < β ≤ 5, the OR of Alfvén waves (AWs) remains nearly stable. However, more slow waves are generated after the HCS crossing, with OR increasing from 13% in the upstream/downstream to 22%; (3) β ≤ 1, the OR of Alfvén and slow waves remains at ∼58% and 20% during the entire crossing, in spite of some irregular fluctuations. The results for the HCS without a clear HPS are similar to the situations of a low β HPS. The parametric decay instability of AWs is proposed as being responsible for the more slow waves generated in the moderate β HPS, and some indirect observational clues are also given.
Knowledge Sharing Factors: Perception Between Junior And Senior Academicians In Malaysian University

Healthy competitions between Malaysian University to achieve the higher ranking throughout the globe provide an interesting background for a research to understand how they practices knowledge sharing (KS) among their academicians to gain competitive advantages. Plenty have been discussed on knowledge sharing but comprehensive understanding of knowledge sharing between academicians especially in regards to different seniority has been less mentioned. This study aimed to identify the comparison between junior and senior academicians on three knowledge sharing driver factors; organizational factor, technological factor and individual factor. This study is carried out with a set of survey among academicians in a Research University (RU) in Malaysia. Results from this study shows that top management under organizational factor and knowledge self-efficacy under individual factor are the most important factor that motivate KS for both junior and senior academicians. Senior academicians also agree that system infrastructure under technological factor is also crucial in knowledge sharing. These findings conclude that the strength of knowledge sharing in RU strives from its top management as well as individual factors in academicians but improvements can be made in areas such as organizational rewards and system quality where both junior and senior academicians only moderately agree that they are important factors in knowledge sharing. Keyword: knowledge sharing, organizational factors, technological factors, individual factors, academicians, Malaysian University, Research University. ————————————————————
Evaluation of buccal cortical bone thickness in wet mandibles from cadavers using computed tomography scan and stereomicroscope

Introduction: Cortical bone thickness is an important factor in mini implant stability. Many studies have evaluated cortical bone thickness by different methods, but this study is a step ahead in measuring cortical bone in wet mandibles from cadavers comparing thickness values from computed tomograms to images from a stereomicroscope (SM). In this study, we investigated buccal cortical bone thickness at three interdental areas using computed tomography (CT) scan and SM. Methods: From the CT scans of 30 wet human cadaveric mandibles, 2-dimensional slices through three interdental area (mesial of canine, interpremolar, and inter-molar) were generated. On these, cortical bone thickness was measured at 2, 4, and 6 mm from the cementoenamel junction (CEJ). The cortical bone thickness at same areas was compared with an SM. Results: By both methods, it was observed that thickness of cortical bone increased from mesial of canines toward the premolar region and then decreased in the molar region. Increase in thickness of cortical bone was observed with increase in height from the CEJ toward the apical region up to 6 mm. CT scans underestimated the measurements as compared to the SM method. Conclusions: The mean buccal cortical bone thickness at all interdental sites at 2, 4, and 6 mm from CEJ was 1.7 ± 0.4 by the CT scan method and 1.9 ± 0.5 by the SM method, indicating that results observed with the CT method were underestimated by 11% than SM method.
Managers’ Resources for Authentic Leadership – a Multi‐study Exploration of Positive Psychological Capacities and Ethical Organizational Climates

While authentic leadership is highly valued in today’s business world, managers do not necessarily have the resources to attain it. Building on conservation of resources theory, we propose a conceptual model to address how personal and contextual resources predict authentic leadership. Study 1 analyzes the day-to-day variability in managers’ positive psychological capacities as personal resources in relation to changes in authentic leadership. In addition, it tests ethical organizational climates as stable, contextual resources for authentic leadership. In Study 2, we replicate our results on the between-person level and extend the research model by exploring promotion focus as a link in the relationship between personal resources and authentic leadership. Evidence from an experience sampling study with 89 managers surveyed daily on 10 consecutive work days (Study 1) and a field survey of 130 managers at two points in time (Study 2) supports the hypothesized role of personal resources and promotion focus for authentic leadership. In both studies, only principled but not benevolent ethical organizational climates emerged as a contextual resource for authentic leadership. We discuss the implications for current management research and practice.
Blind spots: museology on museum research

ABSTRACT Research is considered to be one of four fundamental museum practices, equal to collecting, preserving and display. As such, it is understood to provide the basis for many other activities carried out in museums. Yet research remains an ambiguous component of museum practice, sometimes entirely invisible to the public eye. Moreover, it remains a neglected topic in museology, with only a few publications on the subject since its disciplinary reinvention at the turn of the ’90s. In this article, I explore museological strands towards research in museums and identify gaps in the literature. By carving out a space for a critical analysis of museum research within contemporary museology, my aim is to explore the place of museum research within the wider hierarchy of science. By doing so, I take an epistemological approach to museums as public institutions in the borderland between science and culture.
The Association between Interleukin-10 Gene Polymorphism (-1082 G/A) and Bronchial Asthma with the Relation to Spirometric Parameters in Egyptian Children

Background: Asthma is a chronic inflammatory disorder of the airways in which many cells and cellular elements play a role. Bronchial asthma associated with airway hyper-responsiveness, reversible airway obstruction, and allergen-specific IgE production. Growing evidences suggest the association between IL-10 promoter polymorphism and asthma production. Objective: This study was conducted to evaluate the association of IL-10 promoter polymorphism rs1800896 (-1082 G/A) with asthma and its relation to spirometric parameters. Methods: IL-10 polymorphism (rs1800896) was genotyped using real time PCR technique and IgE serum level was measured by ELISA in 30 asthmatic children and 20 controls. Results: There was highly significant increase in IgE level and Eousenophil (%) in asthmatic children compared to control group (p= 0.000 and 0.002). There was significant association between IL-10 polymorphisms (rs1800896) and bronchial asthma.Conclusion: The results of this study suggest that the IL-10 -1082 G/A polymorphism can be associated with susceptibility to pediatric asthma and can be related to reduced respiratory functions between asthmatics.
Small bowel obstruction due to dried fruit and vegetable bezoars in paediatric patients of northern India.

Introduction: Many foods have been implicated in bezoar obstruction especially sun dried apricots, peaches, and prunes. Dried fruits and vegetable being hygroscopic imbibe water, swell in size and cause mechanical small bowel obstruction. We hereby submit our experience of dealing with patients who presented with acute small bowel obstruction (ASBO) due to dried phytobezoars. Materials and methods: This was a retrospective study which was conducted from March 2017 to March 2012. Operative records of the patients with ASBO due to phytobezoars were retrieved from Hospital Records Section. The clinical details, investigative work up, operative findings and intervention and type of bezoars were noted. Results: Over the period of 5 years, 12 patients of phytobezoars were admitted in the department. The mean age of the patients was 1.85 years with 7(58.3%) males and 5 females (41.6.5%). Vomiting was most common and was present in all the patients, bilious in 11 (91.7%). The other features included abdominal pain in 10 (83.3%), abdominal distension in 8 (66.7%), failure to pass stools in 9 (75%), failure to pass flatus in 9 (75%), diarrhoea 16 (25%), bleeding per rectum 2 (16.6% patients). All the patients were operated in emergency settings within the period of 8 ± 3 hours of admission. There were no significant operative complications and average hospital stay was 5.2±1 days. Conclusion: Dry fruits and vegetables like apricot, turnip and peach can lead to bezoar formation which subsequently leads to acute small bowel obstruction in these infants and young children. We also want to impress upon the treating physicians to keep in mind the probability of phytobezoars obstruction in patients presenting with mechanical ASBO especially in patients from Himalayan regions.
LightPAFF: A Two-Stage Distillation Framework for Pre-training and Fine-tuning

While pre-training and fine-tuning, e.g., BERT~\citep{devlin2018bert}, GPT-2~\citep{radford2019language}, have achieved great success in language understanding and generation tasks, the pre-trained models are usually too big for online deployment in terms of both memory cost and inference speed, which hinders them from practical online usage. In this paper, we propose LightPAFF, a Lightweight Pre-training And Fine-tuning Framework that leverages two-stage knowledge distillation to transfer knowledge from a big teacher model to a lightweight student model in both pre-training and fine-tuning stages. In this way the lightweight model can achieve similar accuracy as the big teacher model, but with much fewer parameters and thus faster online inference speed. LightPAFF can support different pre-training methods (such as BERT, GPT-2 and MASS~\citep{song2019mass}) and be applied to many downstream tasks. Experiments on three language understanding tasks, three language modeling tasks and three sequence to sequence generation tasks demonstrate that while achieving similar accuracy with the big BERT, GPT-2 and MASS models, LightPAFF reduces the model size by nearly 5x and improves online inference speed by 5x-7x.
The same course, different access: the digital divide between urban and rural distance education students in South Africa

ABSTRACT Access to education is a significant determinant in future success, not only for a country but equally for individuals. Higher Education (HE) thus is an integral part of the Sustainable Development Goals and vital in supporting African development. Despite this, there is often a lack of access to HE in many parts of Africa, distance education can subsequently play an important role in increasing access to education by providing materials online. Even though institutions such as the University of South Africa, a provider of Open Distance Learning (ODL), can open access to HE for many marginalised and peripheral communities, we cannot separate access to ODL education from the debate of access to ICTs. Students in urban areas have a significantly different educational experience to students with poor ICT access in urban, peri-urban and rural areas. This paper explores the nature of access to ICT and how this affects students’ ability to access HE.
Virus-associated Rhabdomyolysis in Children

Purpose: Virus-associated rhabdomyolysis is very rare. We report 15 patients with rhabdomyolysis caused by various viruses. Methods: Fifteen patients who were diagnosed with rhabdomyolysis and a viral infection were included in this study. Clinical, laboratory, and radiologic findings were evaluated through retrospective chart reviews. Results: Chief complaints were severe bilateral lower leg pain and leg weakness. The median age was 5.7 years. The male:female ratio was 2:5. The viral infections were caused by influenza virus B, parainfluenza virus, and rhinovirus. One patient with influenza virus B had coinfection with coronavirus. Median initial laboratory values and ranges were as follows: serum creatinine, 0.4 (0.1-0.5) mg/dL; serum aspartate transaminase, 124 (48-1,098) IU/L; serum alanine transaminase, 30 (161,455) IU/L; serum creatine kinase, 2,965 (672-16,594) IU; serum lactate dehydrogenase, 400 (269-7,394) IU/L; serum myoglobin, 644 (314-3,867) ng/mL; urine myoglobin, 3 (3-10,431) ng/mL. All patients recovered without complications. Conclusion: This is the first report of the simultaneous occurrence of rhabdomyolysis caused by various viruses. This is also the first report of rhinovirus-associated rhabdomyolysis.
