Published: April 2022

The paper presents a series of results regarding the application of GNSS technology for measuring displacements to earth dams. An appropriate horizontal and vertical deformation-tracking network must be established for the rapid monitoring of earthmoving movements. Data obtained from the monitoring network can be used in the earth dam stability analysis program. Periodic tracking of earth dams using GNSS technology provides high accuracy of spatial distortions. The results of the paper show the application of GNSS technology to monitor the deformations of the Podisu earth dam located on the Sheep Valley River in Iasi County. In the first stage of research (2019 and 2020), the local geodetic tracking network was created. To monitor the dam, four control landmarks were placed on the crest of dam and seven landmarks on the downstream slope. In the second stage of the research (year 2021) the measurements of the displacements at the earth dam were performed. The GNSS monitoring method has the advantage of positioning the target quickly, statically, and with high accuracy. The measurements used fixed stations located at two points in the local geodetic network. Four Trimble GNSS receivers were used for the measurements. The resulting data was processed using the Trimble Business Centre program. The obtained results were analysed in comparison with those existing in the design documentation and technical expertise of the dam. The results highlight the presence of displacements on the crest of a dam and slopes of the dam. The final findings highlight the performance of GNSS technology in the monitoring process, where it provides millimetre-accurate accuracy with high spatial and temporal accuracy.

Published: April 2022

Agribusiness entrepreneurship has become an important component for economic development due to its significant role in creating job opportunity and improving the livelihood of a community. This study aims to investigate the role of perceived social status, job security on agribusiness entrepreneurial intention as well as to examine the moderating role of entrepreneurial education. Quantitative research design was applied using university students as the sample. The result of this study demonstrated that moderating effects of entrepreneurial education on the relationship between perceived social status and agribusiness entrepreneurial intention was not established, thus, called for exploring this moderating effect in other contexts.  However, this study revealed that entrepreneurial education moderates the relationship between job security and agribusiness entrepreneurial intention.  As an implication to the policy, the government needs to promote agribusiness entrepreneurship as a money-spinning career and uplift the status of agribusiness in aiming to attract the Gen Y to participate in this sector.

Satisfaction questionnaires for residential care in child psychiatry: a systematic review

Background. The measurement of patient satisfaction in child psychiatry is used for evaluation, quality projects and scientific research. It is recommended to use instruments with sufficient validity and reliability.

Methodology. The goal of this systematic review is to make an overview of the questionnaires that are currently used in residential child psychiatric care, and to evaluate the quality of those instruments. A search was performed in the databases Medline and Cochrane Library. Studies with patients aged below 18 years or their parents, who have used residential psychiatric care, were included. The studies were published in peer-reviewed magazines in Dutch, French or English. The quality of the instruments was evaluated based upon their psychometric properties (using the COSMIN (‘Consensus-based Standards for the Selection of Health Measurement Instruments’) criteria) and descriptive features were compared.

Results. In 50 relevant articles, 44 questionnaires were found. For 31 questionnaires, psychometric properties were mentioned. Validity was determined more frequently than reliability (30 versus 2 questionnaires).

Conclusion. Questionnaires YSS (Youth Services Survey) and YSSF (Youth Services Survey for Families) are recommended to use because of their good content validity and internal consistency.

The dilated pupil and brain herniation
Authors:   Hull Royal Infirmary, Hull, UK, Pearce JMS
Published: April 2022

This paper recalls the descriptions and early ideas about the dilated pupil accompanying raised intracranial pressure resulting from head injuries and space-occupying lesions. The observation of the ominous fixed, dilated pupils in those with expanding brain lesions dates to Richard Bright and Jonathan Hutchinson in the 19th century, but its significance and mechanisms were only debated in the early years of the 20th century. Compression or stretching of the oculomotor nerve were considered possible causes, but the related mechanisms of coning and the importance of lateral shift were only more recently realised.
Postconcussion Syndrome / Disorder or Mild Traumatic Brain Injury: diagnostic issues and treatment
Authors:   Hertfordshire Neurological Services, UK, Freedland Daniel
Published: April 2022

Traumatic brain injury at the milder end of the spectrum is far more common than the moderate-severe spectrum. Mild traumatic injury (mTBI) accounts for approximately 80% of traumatic brain injuries [1]. Traumatic brain injuries at the milder end of the spectrum which lead to persisting difficulties have been referred to as postconcussion syndrome / postconcussion disorder [2,3]. Individuals with persistent difficulties following a traumatic brain injury at the milder end of the spectrum may be assessed and treated by Neurology, Neuropsychology, and Neuropsychiatry. There has been ongoing research looking at outcomes following traumatic brain injury at the milder end of the spectrum, the validity of postconcussion syndrome/disorder, and treatment of symptoms following milder traumatic brain injuries. This paper will review some of the research in these important areas within neurorehabilitation.
Edward Nettleship and Optic neuritis
Authors:   Hull Royal Infirmary, Hull, UK, Pearce JMS
Published: April 2022

Arabic texts of the ninth century described loss of sight as one form of ocular paralysis. Some early descriptions of amaurosis in retrospect probably describe optic neuropathy but its nature and defining physical signs arose from Helmholtz’s ophthalmoscope in 1845. In 1864 von Gräfe and later Thomas Buzzard and Clifford Allbutt gave detailed accounts, but the most important description was the 1884 work of the ophthalmologist Edward Nettleship, which is here recounted.
The fatal illness of Oscar Wilde
Authors:   Hull Royal Infirmary, Hull, UK, Pearce JMS
Published: April 2022

The literary genius of Oscar Wilde has been sullied and besmirched by his infamous entanglement with Lord Alfred Douglas for “gross indecency” leading to his subsequent imprisonment for two years. After release he developed what was certified as “cerebral meningitis” in November 1900, from which he died. The much disputed cause is discussed. The claims for neurosyphilis are wholly inadequate; a chronic middle ear infection with cholesteatoma and intracranial suppuration is here suggested as the basis of his fatal illness. Had he lived in the 21st century Oscar Wilde would not have been so cruelly punished, may have received effective treatment, and thus been spared to provide much more of his wit and elegant plays, stories and poetry.
Choked disc, optic neuritis, and papilloedema
Authors:   Hull Royal Infirmary, Hull, UK, Pearce JMS
Published: April 2022

Before the invention of the ophthalmoscope in 1851, doctors were neither able to recognise papilloedema nor to diagnose accurately intracranial hypertension, malignant hypertension and inflammatory and systemic disorders affecting the optic fundus. This paper seeks to uncover early descriptions and experiments that tried to unravel the causes of the swollen optic disc, its mechanism and its clinical significance. Papilloedema is a purely descriptive name that requires the underlying cause to be specified.
REFLECTIONS ON LINGUISTIC SIGNIFICANCE AND VOCAL MUSIC: SURAT AL-NASR AS A MODEL
Authors: Ahmed EZZAT Azza Adnan

The internal acoustic music of Surat Al-Nasr depicted the sign of the promise of complete victory and the good tidings of the entry of many creatures to Islam. The feeling of pride and vanity appeared for the coming of victory and conquest, and the vision of entering, represented by the tide in the sound of the thousand in the first verse three times, and the glorification of (lam) the word of majesty, then it calmed down when the Almighty said: In the religion of God) to express entering quietly and smoothly by elongating the tide of the word God, and this is exactly what happened at the beginning of the Islam. The highly “hamza” and “Jeem,” then the repetition of the tide in absolute thousand came to reinforce this, and the syllables and sounds contributed to the stereotyped sound image, and shedding lights on the meaning of the words. We also find that the percentage of open syllables in the surah reached (63.2%) and the movement of conquest (65.3%), in addition to the increase in the percentage of vocalized voices to the whispered by more than double, and this music increases by the increase in the percentage of the closed sound clip closed silently in the last verse to (42.85%) After it was (30%) in the first verse and (27.7%) in the second verse, it is in harmony with the state of praise and forgiveness that requires a kind of reverence, represented by this energetic calm and this quiet of speaking..

Published: April 2022

Bézier curves and surfaces are very important in many areas, especially the manufacturing and aerospace. Surface inspection through visualisation is required to create high-quality surfaces and reduce unwanted products. The smoothness of the surface can be quantified using curvature. In this research, different surfaces types will be generated using the quintic trigonometric Bézier basis function. All the surfaces will be evaluated and analysed using Gaussian and mean curvature. Finally, curvature for each surface type will be mapped using colour-coded mapping and can be further characterised based on their positive and negative curvature values. This insight can also help the designer produce a smooth surface and develop quality products.
Development of q-Rung Orthopair Trapezoidal Fuzzy Einstein Aggregation Operators and Their Application in MCGDM Problems
Authors: Sarkar Arun , Biswas Animesh , Kundu Moitreyee
Published: April 2022

Compared to previous extensions, the q-rung orthopair fuzzy sets are superior to intuitionistic ones and Pythagorean ones because they allow decision-makers to use a more extensive domain to present judgment arguments. The purpose of this study is to explore the multicriteria group decision-making (MCGDM) problem with the q-rung orthopair trapezoidal fuzzy (q-ROTrF) context by employing Einstein t-conorms and t-norms. Firstly, some arithmetical operations for q-ROTrF numbers, such as Einstein-based sum, product, scalar multiplication, and exponentiation, are introduced based on Einstein t-conorms and t-norms. Then, Einstein operations-based averaging and geometric aggregation operators (AOs), viz., q-ROTrF Einstein weighted averaging and weighted geometric operators, are developed. Further, some prominent characteristics of the suggested operators are investigated. Then, based on defined AOs, a MCGDM model with q-ROTrF numbers is developed. In accordance with the proposed operators and the developed model, two numerical examples are illustrated. The impacts of the rung parameter on decision results are also analyzed in detail to reflect the suitability and supremacy of the developed approach.

Surgical Site Infection (SSI) Surveillance Program for Mastectomy in the Department of Surgery of the University of the Philippines-Philippine General Hospital
Authors: Macalindong Shiela S. , Ramirez Arjel D. , Lapitan Marie Carmela M.
Published: April 2022

Background. Mastectomy is a common surgical procedure done worldwide. Surgical site infection (SSI) is a common healthcare-associated infection. Mastectomy SSIs are frequently under-reported.

Objectives. The study aimed to determine the incidence of SSI among mastectomy cases of the Department of Surgery, University of the Philippines – Philippine General Hospital (UP-PGH) during one year of full implementation of the Surgical Site Infection Surveillance Program and evaluate the program’s surveillance follow-up rate.

Methods. This study was an observational practice audit research that included all adult patients who underwent a mastectomy in UP-PGH from January 1, 2018, to January 31, 2019, when the SSI Surveillance Program was fully implemented. SSI was monitored and assessed during the patient’s hospital stay, on the day of hospital discharge, and at 30 days (± 2 days) after surgery, either during an outpatient visit or via phone call by a nurse navigator. SSI frequency for mastectomy was computed both during the in-hospital stay and at 30 days after surgery. Surveillance follow-up rate, defined as the proportion of patients who could follow-up up to 30 days after surgery, was determined.

Results. The 30-day SSI rate for mastectomy was 6.8% (19/279). All 279 patients were followed up to 30 days after surgery. Of the 279 patients, 277 (99.3%) were through clinic visits, one was through phone calls, and one was still admitted to the hospital.

Conclusion. Full implementation of the SSI Surveillance Program for mastectomy in UP-PGH for one year showed a higher SSI rate than in published international literature. The program had a complete 30-day patient follow-up, contributing to more accurate SSI reporting. Implementing an SSI surveillance program with standardized protocols, dedicated personnel, patient education component, and the analysis of the information derived from such programs can improve an institution's quality of surgical care.

Published: April 2022

The development of spatial abilities in young children leads to better achievement in STEAM education and in their daily lives. Early interventions have been shown to be highly effective in developing spatial abilities. In this study, the spatial abilities curriculum of the Greek kindergarten is described, and the use of maps is recommended for inclusion in the curriculum. This study examines kindergarten pupils’ spatial abilities at the end of two consecutive preschool years and determines whether attending kindergarten for one or two years succeeded in developing the participating pupils’ spatial abilities and achieving the goals set by the curriculum. Furthermore, it investigates which spatial abilities can be developed to the greatest and lowest degree and whether there is a statistical difference in achievement between age (1 or 2 years of study) and gender. The research sample consisted of 90 pupils from 5 different kindergarten classes; these pupils had attended kindergarten for 1 year (younger children called pronipia in Greek) or for 2 years (older children called nipia in Greek). A questionnaire survey was used to collect data for analysis. It was found that the goals set by the curriculum were not satisfactorily met. Older children, as expected, performed better and there was no statistical difference between boys and girls for the total performance. This paper is part of a wider study that aims to investigate pupils’ spatial abilities. It proposes an effective teaching intervention with the use of two large-scale giant maps and appropriate teaching material to develop kindergarteners’ spatial abilities

Published: April 2022

The focus of this paper is the analysis of spatio-temporal patterns of commercial activities in the area of Exarchia-Neapoli, in Athens, during the last decade. A significant downturn during the financial crisis has left its mark on commerce along with all other sectors of the economy in Greece. However, there is poor geographical analysis up to this date, depicting the changes in spatial concentration and dispersion of shops, flourishing and decaying sectors and their spatial footprint. The main purpose of this study is to reveal these transformations in a central mixed-use neighborhood of Athens. The type of commercial activity of ground floor stores and offices in the area is recorded at three different points in time (2009, 2014, 2019). After the collection and categorization of data, spatial analysis was carried out using geostatistical indicators such as mean center and standard deviational ellipse and spatial patterns were determined through nearest neighbor analysis. Τhe analysis over space and time reveals trends and patterns of clustering and avoidance respectively, both within commercial uses and between different ones. Furthermore, their correlation with the centrality of the network (space syntax analysis) reveals not only proximity relationships, but also their strength and resilience over time. Finally, we discuss our findings in relation to the dynamics of commerce in the Exarchia area and propose scaled-up research opportunities.

Published: April 2022

The answer script analysis is a crucial a part of assessing student’s performance. Typically, an answer script analysis is finished manually that typically are often biased. The analysis depends on varied factors like mood swing of the authority, the inter-relation between the student and authority. To boot, analysis could be a very tedious and long task. During this paper, a linguistic communication processing-based methodology is shown for automatic answer script analysis. Our experiment consists of text extraction from answer script, measuring various similarities between summarized extracted text and hold on correct answers, so assign a weight value to every calculated parameters to attain the solution script. For outline generation from the extracted text, we've got used keyword-based summarisation techniques. Here four similarity measures (Cosine, Jaccard, Bigram, and Synonym) square measure used as parameters for generating the ultimate mark. Automatic analysis of answer scripts has been found terribly helpful from our experiments, and infrequently the assigned marks is that the same as manually scored marks.

Hillî, bilindiği gibi, Şîa içerisindeki iki önemli farklılaşma hareketinden biri olan Usûlîliğin en önemli temsilcilerinden biridir. Bununla birlikte Hillî yaşadığı dönemde İmâmiyye mezhebinin etkili savunucularından biri olarak öne çıkmıştır. Özellikle imâmet anlayışında tavizsiz bir tutum sergilemiş olan Hillî, İmâmiyye Şîası dışındaki mezheplerin tamamına yakınını ötekileştirmiştir. Ona göre dünya ve ahiret işleri için en doğru ve sağlam yol İmâmiyye Şîası’nın yolu olup bu hususta başka hiçbir mezhebe itibar edilmemelidir. Ayrıca Hillî, İlhanlı sultanı Olcaytu’yu etkilemesi sayesinde devlet içerisinde itibar sahibi bir alim olmanın ötesinde devletin desteğini tamamıyla arkasına almayı başarabilmiş bir şahsiyettir. Onun kendi mezhebine olan güveni ve diğer mezheplere yönelik bakışı bu imkânı elde etmesinde etkili olduğu gibi bu imkân, onun diğer mezheplere yönelik yaklaşımını da büyük oranda şekillendirmiştir. Bu bağlamda Hillî’nin İmâmiyye dışındaki diğer mezheplere bakışı, eserleri ve düşüncelerinden hareketle ortaya konacaktır.

Maritime transportation is the key element of global trade in recent years. Moreover, container shipping companies aim to complete door-to-door cargo operation with lower costs and increased speed. Determination of delays and possible accidents play vital role on cargo transportation process in a container terminal. In this scope, 65 container terminal accident reports are evaluated with Fuzzy C-means method to cluster within scope of root cause analysis. Three, four, and five number of clusters are created to determine possible causes of accidents. Two container terminals located in Turkey have diverse cargo operation capacity such as mobile and quay cranes. Accident cases are grouped in the view of relation of operations as cargo and port. Port related accidents are found mainly as related with maintenance processes. and occurred in weekdays. On the other hand, cargo related accidents occurred in weekends and during night shifts. In this scope, the results revealed that Fuzzy C-Means method could be used to analyse container terminal accidents.

Abstract. As evidence of adverse health effects due to air
pollution continues to increase, the World Health Organization (WHO) recently
published its latest edition of the global air quality guidelines (World Health Organization, 2021). Although
not legally binding, the guidelines aim to provide a framework in which
policymakers can combat air pollution by formulating evidence-based air
quality management strategies. In the light of this, the European Union has
stated its intent to revise the current ambient air quality directive
(2008/50/EC) to more closely resemble the newly published WHO
guidelines (European Commission, 2020). This article provides an informed
opinion on selected features of the air quality directive that we believe
would benefit from a reassessment. The selected features include discussion
about (1) air quality sensors as a part of a hierarchical observation network,
(2) the number of minimum sampling points and their siting criteria, and (3) new
target air pollution parameters for future consideration.

Abstract. Both weather–climate models and ice cloud remote sensing applications need to obtain effective ice crystal scattering (ICS) properties and the
parameterization scheme. An irregularly shaped Voronoi ICS model has been
suggested to be effective in remote sensing applications for several
satellite programs, e.g., Himawari-8, GCOM-C (Global Change Observation
Mission–Climate) and EarthCARE (Earth Cloud Aerosol and Radiation Explorer).
As continuation work of Letu et al. (2016), an ice cloud optical property
parameterization scheme (Voronoi scheme) of the Voronoi ICS model is
employed in the Community Integrated Earth System Model (CIESM) to simulate
the optical and radiative properties of ice clouds. We utilized the
single-scattering properties (extinction efficiency, single-scattering
albedo and asymmetry factor) of the Voronoi model from the ultraviolet to
the infrared, combined with 14 408 particle size distributions obtained from
aircraft measurements to complete the Voronoi scheme. The Voronoi scheme and
existing schemes (Fu, Mitchell, Yi and Baum-yang05) are applied to the CIESM
to simulate 10-year global cloud radiative effects during 2001–2010. Simulated
globally averaged cloud radiative forcings at the top of the atmosphere (TOA)
for Voronoi and the other four existing schemes are compared to the Clouds and
the Earth's Radiant Energy System Energy Balanced and Filled (EBAF) product.
The results show that the differences in shortwave and longwave
globally averaged cloud radiative forcing at the TOA between the Voronoi
scheme simulations and EBAF products are 1.1 % and 1.4 %, which are
lower than those of the other four schemes. Particularly for regions (from
30∘ S to 30∘ N) where ice clouds occur frequently, the
Voronoi scheme provides the closest match with EBAF products compared with the
other four existing schemes. The results in this study fully demonstrated
the effectiveness of the Voronoi ICS model in the simulation of the
radiative properties of ice clouds in the climate model.

Abstract. Volatile organic compounds (VOCs) tend to be consumed by atmospheric
oxidants, resulting in substantial photochemical loss during transport. An
observation-based model was used to evaluate the influence of photochemical
loss of VOCs on the sensitivity regime and mechanisms of ozone formation.
Our results showed that a VOC-limited regime based on observed VOC
concentrations shifted to a transition regime with a photochemical initial
concentration of VOCs (PIC-VOCs) in the morning. The net ozone formation
rate was underestimated by 3 ppb h−1 (∼36 ppb d−1) based on the measured VOCs when compared with the PIC-VOCs. The relative contribution of the RO2
path to ozone production based on the PIC-VOCs accordingly increased by
13.4 %; in particular, the contribution of alkene-derived RO2
increased by approximately 10.2 %. In addition, the OH–HO2 radical
cycle was obviously accelerated by highly reactive alkenes after accounting
for photochemical loss of VOCs. The contribution of local photochemistry
might be underestimated for both local and regional ozone pollution if
consumed VOCs are not accounted for, and policymaking on ozone pollution
prevention should focus on VOCs with a high reactivity.
The impact of molecular self-organisation on the atmospheric fate of a cooking aerosol proxy

Abstract. Atmospheric aerosols influence the climate via cloud
droplet nucleation and can facilitate the long-range transport of harmful
pollutants. The lifetime of such aerosols can therefore determine their
environmental impact. Fatty acids are found in organic aerosol emissions
with oleic acid, an unsaturated fatty acid, being a large contributor to
cooking emissions. As a surfactant, oleic acid can self-organise into
nanostructured lamellar bilayers with its sodium salt, and this
self-organisation can influence reaction kinetics. We developed a kinetic
multi-layer model-based description of decay data we obtained from
laboratory experiments of the ozonolysis of coated films of this
self-organised system, demonstrating a decreased diffusivity for both oleic
acid and ozone due to lamellar bilayer formation. Diffusivity was further
inhibited by a viscous oligomer product forming in the surface layers of the
film. Our results indicate that nanostructure formation can increase the reactive half-life of oleic acid by an order of days at typical indoor and
outdoor atmospheric ozone concentrations. We are now able to place
nanostructure formation in an atmospherically meaningful and quantifiable
context. These results have implications for the transport of harmful
pollutants and the climate.
Climate and ocean circulation in the aftermath of a Marinoan snowball Earth
Authors: Ramme Lennart , Marotzke Jochem
Published: April 2022

Abstract. When a snowball Earth deglaciates through a very high atmospheric CO2 concentration, the resulting inflow of freshwater leads to a stably stratified ocean, and the strong greenhouse conditions drive the climate into a very warm state. Here, we use a coupled atmosphere–ocean general circulation model, applying different scenarios for the evolution of atmospheric CO2, to conduct the first simulation of the climate and the three-dimensional ocean circulation in the aftermath of the Marinoan snowball Earth. The simulations show that the strong freshwater stratification breaks up on a timescale of the order of 103 years, mostly independent of the applied CO2 scenario. This is driven by the upwelling of salty waters in high latitudes, mainly the Northern Hemisphere, where a strong circumpolar current dominates the circulation. In the warmest CO2 scenario, the simulated Marinoan supergreenhouse climate reaches a global mean surface temperature of about 30 ∘C under an atmospheric CO2 concentration of 15×103 parts per million by volume, which is a moderate temperature compared to previous estimates. Consequently, the thermal expansion of seawater causes a sea-level rise of only 8 m, with most of it occurring during the first 3000 years. Our results imply that the surface temperatures of that time were potentially not as threatening for early metazoa as previously assumed. Furthermore, the short destratification timescale found in this study implies that Marinoan cap dolostones accumulated during the deglacial period, given that they were deposited under the influence of a freshwater environment.
Dynamic boreal summer atmospheric circulation response as negative feedback to Greenland melt during the MIS-11 interglacial
Authors: Crow Brian R. , Prange Matthias , Schulz Michael
Published: April 2022

Abstract. The unique alignment of orbital precession and obliquity
during the Marine Isotope Stage 11 (MIS-11) interglacial produced perhaps
the longest period of planetary warmth above preindustrial conditions in
the past 800 kyr. Reconstructions point to a significantly reduced Greenland ice sheet volume during this period as a result, although the remaining extent and volume of the ice sheet are poorly constrained. A series of time slice simulations across MIS-11 using a coupled climate model indicates that boreal summer was particularly warm around Greenland and the high latitudes
of the Atlantic sector for a period of at least 20 kyr. This state of
reduced atmospheric baroclinicity, coupled with an enhanced and
poleward-shifted intertropical convergence zone and North African monsoon,
favored weakened high-latitude winds and the emergence of a single, unified
midlatitude jet stream across the North Atlantic sector during boreal
summer. Consequent reductions in the lower-tropospheric meridional eddy heat
flux over the North Atlantic therefore emerge as negative feedback to
additional warming over Greenland. The relationship between Greenland
precipitation and the state of the North Atlantic jet is less apparent, but
slight changes in summer precipitation appear to be dominated by increases
during the remainder of the year. Such a dynamic state is surprising, as it
bears stronger resemblance to the unified-jet state postulated as typical
for glacial states than to the modern-day interglacial state.
