This study aims to assess knowledge, attitude and behavior in sexual and reproductive health (SRH) including comprehensive sexuality education (CSE) among 439 first year students; 213 sciences and 226 arts students from 5 Faculties of University Malaysia Sabah (2016-2017). Exposure of Malaysian students to sexual education is limited to science subjects which are only being taught at upper elementary and secondary high school levels. Arts students are less exposed to sexual education across Malaysia as it is delivered in Basic Science subject only. It was a university-based, cross-sectional, descriptive study. Pretested self- administered questionnaire was anonymously completed by all participants and was conducted from November 2016 to January 2017. Students’ demographic characteristics from Science and Arts streams were same except females, Sabah ethnics and Malays were more in Arts. Awareness of HIV/AIDS, Condom, Wet dream, COC pills and abortion services were more in Science students and statistically significant. 34.3 % and 81.2% of Science students agreed that CSE should be introduced in primary and secondary school but not statistically significant. 22 out of 439 students were sexually active. Science students had more knowledge about SRH and favourable attitude towards sexuality education but less favourable behaviour of watching and reading pornographic materials. It was concluded that there were gaps in knowledge, attitude and behaviour of SRH and need to remedy these by giving appropriate CSE classes to first-year university students in an elective module according to their culture and religious beliefs in accord with International Technical Guidance on Sexuality Education (ITGSE).

Ambulance response time is one of the key performance of ambulances services. The objective of this study is to determine the factors associated with delayed ambulance response time in Hospital Universiti Sains Malaysia (HUSM). This was a cross sectional study conducted in Department of Emergency Medicine, Hospital Universiti Sains Malaysia (EDHUSM) between January 2016 to January 2017. A total of 300 ambulance calls were included in our analysis. Data were collected by ambulance paramedic using validated ambulance form. All ambulance forms with missing data were excluded from this study. Of the 300 ambulance calls within the study periods, 254 cases (84.7%) were determined to have delayed ambulance response time. Current ambulance response time is 14 minutes with interquartile range of 5 minutes. Factors which showed significant association delayed ambulance response time include distance from hospital, location, type of emergency and ambulance mechanism. The odd of delayed ambulance response time by every increase in distance unit was 1.59 (95% CI, 1.37 to 1.85). For location type, the odd of delayed ambulance response time for public location as compared to road was 0.13 (95% CI, 0.04 to 0.45). For ambulance mechanism, the odd of delayed ambulance response time for beacon type as compared to siren type was 0.22 (95% CI, 0.01 to 0.69). Further intervention should be initiated based on our findings to improve current ambulance response time.

Secondhand smoke (SHS) carries many health risks and is associated with diseases and premature deaths among nonsmoking adults and children.  Despite many health promotions and legislative measures executed by the government to protect the public from SHS, the prevalence of SHS exposure is still high.  Personal appropriate practices to avoid exposure are crucial especially at home or private area. Therefore, the current study focused on describing individual preventive practices on SHS and determining its associated factors. A cross sectional study was conducted among 250 adults in a village, Kuala Terengganu. Data were collected using self-administered questionnaires.  Multiple logistic regression analysis was performed to determine the association between all independent variables and the SHS preventive practice status. The prevalence of SHS exposure was 66.0%.  Majority of the respondents (77.2%) has good knowledge on SHS.  Nevertheless, despite having good knowledge, a large proportion of them showed poor attitude toward SHS (77.6%) and poor preventive practices (61.2%).  Poor preventive practices on SHS were significantly associated with being older (OR­adj: 1.0206, 95% CI: 1.0004, 1.0412), female (OR­adj: 2.0644, 95% CI: 1.0753, 3.9635), smoker (OR­adj: 12.1107, 95% CI: 4.0630, 36.0991), not having existing tobacco-related morbidity (OR­adj: 3.6795, 95% CI: 1.1795, 11.4786), and poor attitude towards SHS (OR­adj: 4.1871, 95% CI: 2.0955, 8.3665). The preventive practices of SHS among the villagers were poor despite showing acceptable level of knowledge.  Hence, health awareness on the potential impact of SHS to the public as well as instilling appropriate behavior for them to avoid SHS and educate smokers need to be emphasized.

Antibiotic resistance is a global threat to public health, leads to health and economic burden. Studies show that knowledge and attitude towards antibiotic use is poor, especially among rural residents. However, there is no study conducted on knowledge and attitude towards antibiotic use among the public in rural area Malaysia. The aim of this study is to assess knowledge and attitude on antibiotic use among public in rural area Batu Pahat, Johor. This was a cross-sectional study in which closed-ended questionnaires were distributed to 350 rural residents in Batu Pahat by convenience sampling method. The questionnaire was constructed into socio-demographic, antibiotic use and indication, knowledge and attitude towards antibiotic use. The most inappropriate knowledge responses were found for assumption about the effectiveness of antibiotics towards viral infection (69.1%), colds and coughs (57.7%). Only few were aware about the decrease in antibiotic effectiveness following antibiotic overuse (29.1%). Misuse antibiotics for cold (64.0%), expect antibiotics to be prescribed for common cold symptoms (52.6%) and discontinue antibiotics when start feeling better (63.4%) were the several highest inappropriate responses in attitude domain. Significant association was shown between both knowledge level and attitude level with age, gender, educational level, monthly income, occupation related to healthcare, family member’s occupation related to healthcare and most common location seek for healthcare. In conclusion, the rural residents demonstrated moderate knowledge (50%) but negative attitude (56.9%) towards antibiotic use. To cope with antibiotic resistance issue, proper planning on effective methods to promote appropriate use of antibiotics are necessary.

Non-compliance to hygienic practices in contact lens wear is regarded as a significant risk factor for contact lens-related complications. Non-compliant behaviour continues to prevent efforts to improve contact lens safety despite advancements in lens materials and care solutions. The objective of this study was to identify the association between knowledge, compliance and complications of contact lens wear. A cross-sectional design was used and contact lens users among medical faculty students were identified and recruited via convenience sampling throughout October 2013 to March 2014. A total of 36 close-ended questions that focused on knowledge level, compliance to standard contact lens practice, and experience of complications were administered. A total of 188 respondents, majority of females (89.4%; n=168) participated in this study. Although majority had good knowledge level (68.1%; n=128) on care and usage of contact lens while only a small number having moderate knowledge (26.6%; n=50) and poor knowledge (5.3%; n=10), most of them were partially compliant (74.5%; n=140) to the recommended contact lens practices. However, a small group was found to be fully compliant (24.4%; n=46) and the rest being non-compliant (1.1%; n=2). There was a significant association between knowledge on contact lens usage and compliance level to standard practices (p=0.0003). In addition, a significant association also existed between compliance level to recommended practices and risk of complications from contact lens usage (p=0.023). Findings of this study showed the positive association between knowledge of contact lens usage and compliance to recommended practices and negative association between knowledge of contact lens usage and complications experienced by contact lens users. By providing basic knowledge on contact lens care and usage via education, improvement on compliance and enhancement of safety of contact lens wear could invariably be achieved.
In Opposing Community Wisdom: Exposing Lexicon Choices in Kimeru Folklore as Agents of Patriarchy and Gender Bias
Authors: Kinyua Ann Hildah Gatakaa
Published: June 2020

Since time immemorial, communities across the world exhibit gender inequity whereby the feminine gender is viewed as lesser to their male counterparts. Studies indicate that no one is born a man or a woman, but rather the society makes us men or women through acculturation into roles that are conventionally stereotyped as male or female. However, the roles and duties for men and women vary from community to community; some duties are strictly viewed as being for one gender in one community are considered duties for the other gender in another community. For example, among the Ameru, a patriarchal society of Eastern Kenya, no woman can undertake the task of building a shelter, while among the pastoralist communities of Kenya, women build family shelters. This means there are no duties that are strictly for men or women in the world. This paper argues that one way that society makes men and women out of her people is through the language used in community folklore transmitted through formal or informal linguistic interactions. A case is made from a careful examination of the Ameru proverbs, wise sayings, and riddles. It will be shown that the language used in these genres continually exhorts and invites the male gender to manifest macho and positive qualities while at the same time depicts the female gender as feeble, vain, and weak. The paper proposes the repackaging of community folklore and wisdom through language that establishes positive qualities for members of both genders.

Published: June 2020

Backgrounds. Development and testing of new methods of detoxification and anti-inflammatory therapy are important tasks of modern medicine in view of the continuous spread of diseases accompanied by persistent inflammatory reaction and/or accumulation in the body of toxic compounds, and the lack of effectiveness of currently used anti-inflammatory and anti-inflammatory treatments.

Aim of the study: to study the clinical efficacy and safety by the dynamics of disease symptoms and some laboratory biochemical parameters of original highly mineralized products for external use in inflammatory human diseases.

Materials and methods. An uncontrolled pilot study was conducted to investigate the efficacy and safety of highly mineralized products according to the most promising indications to determine appropriate directions for further controlled clinical trials. We recruited 3 patient groups of 10 people each. The first group received compressed wipes highly mineralized in the form of applications to the skin around arthritic joints. In the second group, compression bandages highly mineralized in the form of extensive and prolonged cutaneous applications in the trunk and extremities for detoxification in patients with chronic renal failure were used. The third group received a universal spray highly mineralized to eliminate the manifestations of skin itching in the form of aerosol spraying. Control was performed on the subjective feelings of patients using a visual analogue scale of pain and itching, clinical examination data and the dynamics of some laboratory biochemical parameters such as serum concentration of creatinine, urea, uric acid. Statistical analysis of the results was performed by structural and comparative analysis methods.

Results and discussion. Complete remission of arthritis symptoms after a 10-day course of therapy was achieved in 50% of cases, and other patients showed significant improvement. On a visual analog scale, all patients experienced a decrease in pain intensity of at least 50% during the first 3-4 local napkin compression applications. Results of pilot tests of highly mineralized compression bandages in patients with chronic renal failure indicate some improvement in well-being and a slight decrease in serum concentrations of creatinine and uric acid by 10-30% in the subgroup of patients with initial serum kreatinine concentration to 200 µmol/l. The highly mineralized universal spray provides rapid (within a few seconds to 2 minutes) and complete or almost complete elimination of itching sensations at the site of application for 1 to 12 hours in all patients, regardless of the origin of the itching, but depending on its intensity.

Conclusions. Original highly mineralized products are potentially effective and safe to use in the specified pathology according to the approved application protocols. There is a need for further controlled research in the outlined areas.

Authors: Bogomolov Artemii
Published: June 2020

The aim of our study was to evaluate the diagnostic parameters of immunoblot and Immunocap ISAC methods to determine allergic sensitization to wormwood and hazel in patients with respiratory allergic diseases – allergic rhinitis and bronchial asthma.

Materials and methods. In this study, 40 patients with bronchial asthma and / or allergic rhinitis were examined with two different methods of specific allergic diagnosis (in vitro). The study was open-ended, comparative. Quantitative determination of specific IgE in the serum was performed using the RIDA® AllergyScreen immunoblot method (R-Biopharm AG, Germany) on the basis of the private laboratory of LLC “Allergy-Immunological Center KPP”. Immunocap ISAC testing was performed at “Forpost Allergy and Immunology Clinic”.

Results and Discussion. Among patients, allergic sensitization to wormwood was 27.5% (11 people) in the presence of specific IgE by the Rida AllergyScreen method, 25.0% (10 people) in the presence of specific IgE using ImmunoCAP ISAC; sensitization to hazel allergen was 27.5% (11 people) in the presence of specific IgE on Rida AllergyScreen, 30.0% (12 people) in the presence of specific IgE from ImmunoCAP ISAC.

For the determination of specific IgE to wormwood allergen the immunoblot has a high sensitivity and negative predictive value (100.00% in both cases) compared to ISAC, a high specificity of 96.67% (95% CI: 82.78; 99.92), but a positive predicitive value was 90.91% (95% CI: 59.28; 98.57) and accuracy was 97.50% (95% CI: 86.84; 99.94).

Conclusions. Immunoblot compared to ISAC for the determination of specific IgE to hazel allergen has a relatively high specificity and negative predictive value (92.86% and 89,66%), but the sensitivity and positive predicitive value were 75.00% (95 % CI: 42.81; 94.51) and 81.82% (95% CI: 53.23; 94.68), respectively, and the accuracy of the method was 87.50% (95% CI: 73.20; 95.81).

Superconductor-insulator transition in capacitively coupled superconducting nanowires
Authors: Latyshev Alex , Semenov Andrew G , Zaikin Andrei D
Published: June 2020

We investigate superconductor-insulator quantum phase transitions in ultrathin capacitively coupled superconducting nanowires with proliferating quantum phase slips. We derive a set of coupled Berezinskii-Kosterlitz-Thouless-like renormalization group equations demonstrating that interaction between quantum phase slips in one of the wires gets modified due to the effect of plasma modes propagating in another wire. As a result, the superconductor-insulator phase transition in each of the wires is controlled not only by its own parameters but also by those of the neighboring wire as well as by mutual capacitance. We argue that superconducting nanowires with properly chosen parameters may turn insulating once they are brought sufficiently close to each other.
Conformational Preferences of Fluorine-Containing Agrochemicals and their Implications for Lipophilicity Prediction
Authors: Silva Daniela R , Daré Joyce K , Freitas Matheus P
Published: June 2020

Molecular polarity governs lipophilicity, which in turn determines important agrochemical and environmental properties, such as soil sorption and bioconcentration of organic compounds. Since the C–F bond is the most polar in organic chemistry, the orientation of fluorine substituents originated from the rotation around C–C(F) bonds should affect the polarity and, consequently, the physicochemical and biological properties of fluorine-containing agrochemicals. Accordingly, this study aims to determine the most-likely conformers of some fluorine-containing agrochemicals and correlate their molecular dipole moments with the respective n-octanol/water partition coefficients (log P), in order to investigate the dependence of the lipophilicity with the molecular conformation.

Published: June 2020

The work is devoted to the study of the processes of formation and analysis of the parameters of a functional nanostructure — a superconducting spin valve, which is a multilayer structure consisting of ferromagnetic cobalt nanolayers separated by niobium superconductor nanolayers. The aim of the work was to study the influence of the main parameters of the technological regimes of the formation of these nanosystems: temperature, concentration and spatial distribution of deposited atoms over the surface of the nanosystem on the atomic structure and morphology of the nanosystem.  The studies were carried out by the molecular dynamics method using the many-particle potential of the modified immersed atom method. The temperature in the calculation process was controlled using the Nose-Hoover thermostat. The simulation of the formation of atomic nanolayers by the method of alternating directional deposition of layers of different compositions under high vacuum and stationary temperature conditions is performed. As a result of the studies, the structure and thickness of the formed nanolayers and the distribution of elements in the area of their interface were studied. It is shown that alternating layers of the formed layered nanosystem and their interfaces have a significantly different atomic structure depending on the main parameters of the technological regimes of the formation of layered nanosystems.

Authors: Sitnov Alexander N. , Kochkurova Natalia V.
Published: June 2020

The article gives an assessment of the hydrological regime on the River Tesha sector . The assessment was obtained during the pre-project study of the object and allows making project decisions on clearing the riverbed. The River Tesha Basin has been well studied in the past. However, there was no data based on long-term observation of the river's hydrological regime parameters in the area under consideration; hence, the authors performed calculations for data recovery by interpolation between existing hydrological posts, as well as for obtaining their representative series and determining their hydrological characteristics. Correlation between changes in flow rates and water levels in the river was found, as well as between the riverbed morphological parameters (depth, width, cross-section area) and its hydraulic characteristics (flow rate, flow rates). The completed assessment of the hydrological regime makes it possible to forecast river flooding at high water levels as well as flooding of the surrounding area, and to make project decisions thereafter, including the identification of flooding areas, the dump sites choice, these sites functioning period f that depends on when and for how long they will be flooded during the year.

Authors: Stepanova Anastasia A. , Mikheeva Tatyana A.
Published: June 2020

This article proposes and considers a method for solving the problem of the optimal choice of insulation and sewing materials for the interior of a floating class «P» restaurant. This method is based on the principle of multi-criteria comparison of alternative options [1]. For comparison, most suitable insulation materials for a vessel of this type were selected. Since in modern shipbuilding safety and comfort demands of the interior of the vessels are high, so the requirements for insulation materials on the interior are also high. Various characteristics of insulating and sewing materials, which determine their quality level, were analyzed in details. When studying the characteristics of insulating materials, the technological level and competitiveness of the manufacturer were taken into account. To determine the most suitable insulation material for the interior decoration of the floating restaurant, multi-criteria comparison method was first applied. The determination of the materials competitiveness was made.

DISTINGUISHING COEFFICIENT DRIVEN SENSITIVITY ANALYSIS OF GRA MODEL FOR INTELLIGENT DECISIONS: APPLICATION IN PROJECT MANAGEMENT
Authors: Mahmoudi Amin , Javed Saad Ahmed , Liu Sifeng , Deng Xiaopeng
Published: June 2020

The Distinguishing Coefficient (ξ) is an important parameter of Grey Relational Analysis (GRA),
a flagship multi-criteria decision making (MCDM) model of Grey System Theory, an intelligent and multifaceted field
developed by Chinese scientists in 1980s. However, the scholars widely assume ξ = 0.5. The current study questions
this practice. Also, some scholars have argued that the variation in ξ doesn’t influence the ranking of the factors
through GRA. On contrary, the study demonstrates, the variation in ξ can influence the ranking. This has been shown
through a case involving primary data concerning the perceived relative importance of Project Management Knowledge
Areas (PMKAs). This study is significant for the analysts of uncertain systems, represented by grey or fuzzy systems,
who intend to use GRA for intelligent multi-criteria decision making. It encourages ξ – driven sensitivity analysis
of GRA model before interpreting the results. The study reveals, by tailoring the value of ξ a point can be achieved
where the ranking obtained through GRA can be made most comparable to the other MCDM methods. For comparative analysis
of the GRA based results the study deployed three other MCDM techniques; Analytic Hierarchy Process, Best Worst Method
and Simple Additive Weighting.
Toward Complete Characterization: Prospects for Directly Imaging Transiting Exoplanets

Published: June 2020

High-contrast direct imaging of exoplanets can provide many important observables, including measurements of the orbit, spectra that probe the lower layers of the atmosphere, and phase variations of the planet, but cannot directly measure planet radius or mass. Our future understanding of directly imaged exoplanets will therefore rely on extrapolated models of planetary atmospheres and bulk composition, which need robust calibration. We estimate the population of extrasolar planets that could serve as calibrators for these models. Critically, this population of “standard planets” must be accessible to both direct imaging and the transit method, allowing for radius measurement. We show that the search volume of a direct imaging mission eventually overcomes the transit probability falloff with semimajor axis, so that as long as cold planets are not exceedingly rare, the population of transiting planets and directly imageable planets overlaps. Using current extrapolations of Kepler occurrence rates, we estimate that ∼8 standard planets could be characterized shortward of 800 nm with an ambitious future direct imaging mission like LUVOIR-A and several dozen could be detected at the V band. We show the design space that would expand the sample size and discuss the extent to which ground- and space-based surveys could detect this small but crucial population of planets.
Separating Accretion and Mergers in the Cosmic Growth of Black Holes with X-Ray and Gravitational-wave Observations
Authors: Pacucci Fabio , Loeb Abraham
Published: June 2020

Black holes across a broad range of masses play a key role in the evolution of galaxies. The initial seeds of black holes formed at z ∼ 30 and grew over cosmic time by gas accretion and mergers. Using observational data for quasars and theoretical models for the hierarchical assembly of dark matter halos, we study the relative importance of gas accretion and mergers for black hole growth, as a function of redshift (0 < z < 10) and black hole mass (

). We find that (i) growth by accretion is dominant in a large fraction of the parameter space, especially at

and z > 6; and (ii) growth by mergers is dominant at

and z > 5.5, and at

and z < 2. As the growth channel has direct implications for the black hole spin (with gas accretion leading to higher spin values), we test our model against ∼20 robust spin measurements available thus far. As expected, the spin tends to decline toward the merger-dominated regime, thereby supporting our model. The next generation of X-ray and gravitational-wave observatories (e.g., Lynx, AXIS, Athena, and LISA) will map out populations of black holes up to very high redshift (z ∼ 20), covering the parameter space investigated here in almost its entirety. Their data will be instrumental to providing a clear picture of how black holes grew across cosmic time.
Galactic Cosmic-ray Anisotropies: Electrons Observed by Voyager 1 in the Very Local Interstellar Medium

Published: June 2020

Now over seven years into its journey beyond the heliopause, Voyager 1 continues to return unprecedented observations of energetic particles, magnetic fields, and plasma emissions from the very local interstellar medium. Shortly after its heliopause crossing, Voyager 1 discovered an unusual time-varying galactic cosmic-ray anisotropy, characterized by smoothly changing intensity reductions in particles propagating nearly perpendicular to the magnetic field; outside of this isolated region, cosmic rays appear mostly unvarying, without a significant radial gradient. These small (∼15%) but lasting (∼100 to ∼630 days) anisotropic events are still not fully understood. Nevertheless, they serve as clear markers, together with shorter-lived cosmic-ray intensity enhancements, electron plasma oscillations, and weak laminar shocks, that even beyond the heliopause, the Sun’s variable output significantly influences its surroundings. So far, these unusual energetic particle occurrences have mainly been studied using integrated proton intensities of ∼20 MeV and higher. Using data from the Voyager 1 Cosmic Ray Subsystem, we extend the analysis to electrons, as well as lower energy protons, and discover the surprising new result that the ∼3 to ∼105 MeV electrons remain mostly isotropic and unchanging, in sharp contrast to their proton counterparts. We search for clues to explain this underlying species dependence and rule out potential causes related to instrumental effects, velocity and energy, trapping and energy loss, drifts, and turbulence-induced scattering. We also explore some plausible mechanisms and open the door for more detailed follow-up theories and simulations.
Hard Synchrotron Spectra from Magnetically Dominated Plasma Turbulence
Authors: Comisso Luca , Sobacchi Emanuele , Sironi Lorenzo
Published: June 2020

Synchrotron emission from astrophysical nonthermal sources usually assumes that the emitting particles are isotropic. By means of large-scale two- and three-dimensional particle-in-cell simulations, we demonstrate that the dissipation of magnetically dominated (

) turbulence in pair plasmas leads to strongly anisotropic particle distributions. At Lorentz factors

(here,

is the initial Lorentz factor), the particle velocity is preferentially aligned with the local magnetic field; instead, the highest energy particles are preferentially oriented in the plane perpendicular to the field. This energy-dependent anisotropy leads to a synchrotron spectral flux

that is much harder than for isotropic particles. Remarkably, for

we find that the angle-integrated spectral slope in the slow cooling regime is

for a wide range of turbulence fluctuations,

, despite significant variations in the power-law energy spectrum of nonthermal particles. This is because weaker turbulence levels imprint a stronger degree of anisotropy, thereby counteracting the effect of the steeper particle spectrum. The synchrotron spectral slope may be even harder,

, if the observer is in the plane perpendicular to the mean magnetic field. Our results are independent of domain size and dimensionality. Our findings may help explain the origin of hard synchrotron spectra of astrophysical nonthermal sources, most notably the radio spectrum of pulsar wind nebulae.
