Implementation of the Public Sector New Normal Policy in The Post-COVID-19 Period
Authors: Labolo Muhadam
Published: May 2022

AbstractThe pandemic that continues to sweep several parts of the world, including Indonesia, has pushed the government to immediately innovate and reform legislation, as well as improve public services for the benefit of the larger population. The government should be able to transform or at least shift the governance paradigm that affects bureaucracy and public policy in the New Normal age. As a result, the purpose of this research is to examine the implementation and direction of government policies, particularly during the pandemic and new normal. This study employs a qualitative approach combined with a descriptive-analytic approach. According to the findings of the survey, the pandemic has produced uncertainty in practically all people's lives, whether social, economic, or health-related. The new normal policy eventually resulted in the necessity for new public services. The transition time is an opportunity to adapt and reset outdated public services to new ones. During the new normal, the government implements several alternative solutions to public services, such as changing policy perspectives, allowing for more community involvement, simplifying the preparation of public services—policies, and finally reforming the bureaucracy with reform 4.0, which is more adaptable to the new normal.Keywords: Implementation, Public Policy, Government, COVID-19, New Normal. AbstrakPandemi yang melanda di berbagai belahan dunia, termasuk Indonesia, mendorong pemerintah untuk segera melakukan inovasi dan pembenahan peraturan perundang-undangan, serta meningkatkan pelayanan publik untuk kepentingan masyarakat luas. Pemerintah harus mampu mentransformasi atau setidaknya menggeser paradigma governance yang mempengaruhi birokrasi dan kebijakan publik di era New Normal. Oleh karena itu, tujuan dari penelitian ini adalah untuk mengkaji implementasi dan arah kebijakan pemerintah, khususnya pada masa pandemi dan new normal. Penelitian ini menggunakan pendekatan kualitatif yang dipadukan dengan pendekatan deskriptif-analitik. Menurut temuan survei, pandemi telah menghasilkan ketidakpastian di hampir semua kehidupan masyarakat, baik sosial, ekonomi, maupun terkait kesehatan. Kebijakan new normal pada akhirnya melahirkan kebutuhan akan pelayanan publik yang baru. Masa transisi adalah kesempatan untuk mengadaptasi dan mengatur ulang layanan publik yang lama ke yang baru. Dalam era new normal, pemerintah menerapkan beberapa alternatif solusi pelayanan publik, seperti mengubah cara pandang kebijakan, lebih banyak melibatkan masyarakat, menyederhanakan penyusunan kebijakan—pelayanan publik, dan terakhir melakukan reformasi birokrasi dengan reformasi 4.0 yang lebih adaptif terhadap normal baru.Kata kunci: Implementasi, Kebijakan Publik, Pemerintah, COVID-19, New Normal.

Abanpredease Christology: A Christological Interpretation of Dormaahene’s Chieftaincy Appellations
Authors: Boaheng Isaac
Published: May 2022

The centrality of the person and works of Jesus Christ in Christianity cannot be denied. In relation to his works, Christ holds three offices simultaneously; namely, those of king, priest and prophet. A proper understanding of African traditional kingship may facilitate the African Christian understanding of the kingship of Christ and in the process, give the African audience a contextual expression of the Christian faith. The purpose of this paper is to demonstrate how African Christians can appreciate the kingship of Christ based on their understanding of the traditional chieftaincy institution. To this end, the paper examines relevant aspects of the Dormaa kingdom of Ghana—particularly the Dormaahene’s chieftaincy appellations—from a Christological perspective. The paper used a literature-based research methodology to interpret the appellations Ɔsagyefoɔ and Ɔseadeɛyɔ as Christological titles and then linked them to Ahobammɔ Christology—that is, the protection that Christ offers believers. The main thesis of the paper is that the chieftaincy appellations of the Dormaahene have rich Christology which when developed and promoted from an Akan Christian perspective, will catalyze the decolonization and contextualization of Christianity in Africa. The paper contributes to the Christianization of African chieftaincy institutions. The findings from the paper demand that traditional rulers exercise their authority in accordance with God’s purpose and will for their kingdoms, noting that only God is the Supreme Ruler.

The national question and progressive federalism
Authors: Bryan Pauline , Driscoll Jamie , Clark Katy , Griffin Sean , Murray Andrew , Nelson Kevan , Winter Beth , Foster John
Published: May 2022

These two roundtable discussions hosted by the Marx Memorial Library in May and December 2021 examine Britain’s uniquely centralised capitalist state system during a year of rapid change — when previously devolved economic powers were returned from the European Union to Westminster at the expense of democratic legislatures in Scotland and Wales and potentially England’s regions. The year also saw the initial launch of the Conservative government’s ‘levelling up’ programme, also a largely centrally driven initiative. The discussions, the first in May and the second in December, considered the significance, for a wider agenda of socialist change, of developing movements for ‘radical’ or ‘progressive’ federalism across the regions and nations of Britain to challenge this centralisation.
Prettiness algorithms: Smartphones and the manipulation of taste
Authors: Impett Leonardo
Published: May 2022

Often branded as ‘visual AI’, machine vision is the software technology that allows computers to see the world by interpreting images — used in social media platforms (identifying people in photographs), driverless cars (recognising pedestrians or road signs) and many more sinister applications. Researchers, journalists and activists have found that machine vision systems are biased in many of the same ways as the cultures that produced them. Starting from John Berger’s seminal Marxist analysis of how our culture informs the way we see, this article looks at some of the subtlest types of bias in machine vision systems: the automatic ‘enhancement’ of photos by smartphone cameras.
MODELLING AN AIRCRAFT MAXIMUM ENDURANCE HORIZONTAL FLIGHT FOR AIR TRIALS
Authors: Goncharenko Andriy
Published: May 2022

The paper considers theoretical preparation for the aircraft pre-air-trial. The construction of some mathematical models of a horizontal flight is based upon the material system of variable mass motion. Optimal speed of horizontal flight is obtained as a function of variable mass. This speed is a solution (extremal) of the objective functional of the flying apparatus horizontal flight endurance. The solution delivers maximal value to the objective functional. The main significant assumptions made at the problem setting are: the rate of the aircraft horizontal flight speed change is negligibly small, flying object engines thrust has the horizontal component only, the dependence between aerodynamic coefficients is simplified in approximation with a quadratic parabola; the data used in simulation are abstract, although plausible. It was shown that in spite of the speed changes during the studied flight, the rate of that change plays an unimportant role for the considered case; therefore, such supposition of the rate neglecting is properly grounded. The derived equations allow taking into account the rate when it is the matter of importance. Since the presented study is the simplified one, the obtained results could be considered as some reference values to be tested and possibly approached to.
Prevalence of Thermal Nonequilibrium over an Active Region
Authors: Şahin Seray , Antolin Patrick
Published: May 2022

Recent observations have shown that besides the characteristic multimillion degree component, the corona also contains a large amount of cool material called coronal rain, whose clumps are 10–100 times cooler and denser than the surroundings and are often organized in larger events, termed showers. Thermal instability (TI) within a coronal loop in a state of thermal nonequilibrium (TNE) is the leading mechanism behind the formation of coronal rain but no investigation on showers exists to date. In this study, we conduct a morphological and thermodynamic multiwavelength study of coronal rain showers observed in an active region (AR) off-limb with IRIS and the Solar Dynamics Observatory, spanning chromospheric to transition region and coronal temperatures. Rain showers were found to be widespread across the AR over the 5.45 hr observing time, with an average length, width, and duration of 27.37 ± 11.95 Mm, 2.14 ± 0.74 Mm, and 35.22 ± 20.35 minutes, respectively. We find a good correspondence between showers and the cooling coronal structures consistent with the TNE–TI scenario, thereby properly identifying coronal loops in the “coronal veil”, including the strong expansion at low heights and an almost zero expansion in the corona. This agrees with previous work suggesting that the observed zero expansion in the EUV is due to specific cross-field temperature distribution. We estimate the total number of showers to be 155 ± 40, leading to a TNE volume of 4.56 ± [3.71] × 1028 cm3, i.e., on the same order of the AR volume. This suggests a prevalence of TNE over the AR indicating strongly stratified and high-frequency heating on average.

Fast delivery of melatonin from electrospun blend polyvinyl alcohol and polyethylene oxide (PVA/PEO) fibers
Authors: Emerine Rachel , Chou Shih-Feng
Published: May 2022

Water-soluble polymers possess great advantages in current drug delivery systems, such as fast delivery through polymer matrix dissolution as well as promoting solid dispersion of poorly water-soluble drugs. In this work, water-soluble polyvinyl alcohol (PVA) and polyethylene oxide (PEO) were blended (50/50) to electrospin with and without the incorporation of a model drug, melatonin (MLT), at various blend polymer concentrations. Results suggested that increasing blend PVA/PEO solution concentrations, up to 7 wt%, promoted the formation of smooth and defect-free drug-incorporating fibers with an average fiber diameter ranged from 300 to 700 nm. Mechanical properties of the blank and MLT-loaded PVA/PEO fibers showed dependence on fiber morphologies and fiber mat structures, due to polymer concentrations for electrospinning. Furthermore, the surface wettability of the blend PVA/PEO fibers were investigated and further correlated with the MLT release profile of the fibers. Results suggested that fiber mats with a more well-defined fiber structure promoted a linear release behavior within 10 minutes in vitro. These drug-incorporated fibers were compatible to human umbilical vein endothelial cells (HUVECs) up to 24 hours. In general, this work demonstrated the structure-property correlations of electrospun PVA/PEO fibers and their potential biomedical applications in fast delivery of small molecule drugs.
How are urbanization, energy consumption and globalization influencing the environmental quality of the G-7?
Authors: Khalid Laila , Hanif Imran , Rasul Farhat
Published: May 2022

Many developed countries including G-7 became part of the Kyoto Protocol for improving their environmental quality in 2005. Its main goals were to develop national-level programs for energy conservation and the eradication of greenhouse gas emissions. To achieve such goals, certain policy measures including reduction in deforestation, urban population and promotion of renewable energy consumption were adopted. This study aims to examine the consequences of these policies on the environmental quality of G-7 from 1988 to 2018. LLC and IPS unit root tests were applied to check the stationarity of analyzed variables. The results of Pedroni and Kao's co-integration tests proved the long-run relationship between the dependent and explanatory variables. The application of multiple cross-sectional dependence tests revealed that the cross-sections are independent of each other. The findings of the panel Autoregressive distributed lag (ARDL) model exhibited that urbanization, economic growth and nonrenewable energy consumption are hampering the environmental quality. While renewable energy consumption and globalization are improving it in the long term. Urbanization, renewable and nonrenewable energy consumption significantly improve the environmental quality during the short term whereas globalization insignificantly deteriorates the environment. The study confirms the presence of reversed U environmental Kuznets curve between urbanization and carbon emissions with a turning point at 80 per cent of urbanization. The study suggests that the transformation of energy consumption from nonrenewable to renewable sources and strict compliance with environment management policies will prove prolific for improving the environmental quality of G-7.
The Nutcracker Syndrome
Authors: Ismailoglu Tahir
Published: May 2022

Nutcracker syndrome (NCS) is a rare condition caused by the compression of the left renal vein between the abdominal aorta and the superior mesenteric artery. NCS may present with unexplained hematuria. This case report presents a 43-year-old healthy female without any complaints who had newly-detected hematuria in urinalysis during her annual examination. Her physical examination and the whole abdominal ultrasonography failed to explain the cause of hematuria. Further investigation with contrast-enhanced upper abdominal computed tomography revealed a NCS. In unexplained cases of asymptomatic hematuria NCS should be taken into account after excluding other preliminary diagnoses.
Piloting a constructive feedback model for problem-based learning in medical education
Authors: Pangastuti Dwiretno , Widiasih Natalia , Soemantri Diantha
Published: May 2022

Purpose: Constructive feedback is key to successful teaching and learning. The unique characteristics of problem-based learning (PBL) tutorials require a unique feedback intervention. Based on the review of existing literature, we developed a feedback model for PBL tutorials, as an extension of the feedback facilitator guide of Mubuuke and his colleagues. This study was aimed to examine the perceptions of students and tutors on the feedback model that was piloted in PBL tutorials.Methods: This study employed a qualitative research design. The model was tested in nine online PBL sessions, selected using the maximum variation sampling strategy based on tutors’ characteristics. All sessions were observed by the researcher. Afterwards, tutors and students in the PBL sessions were interviewed to explore their perceptions of the model.Results: Three themes were identified based on the perceptions of the tutors and students: cognitive changes, behavioral changes, and challenges of the use of the feedback model. Both tutors and students benefited from improved cognition and behavior. However, the use of the feedback model still encountered some challenges, such as limited sources of feedback data, flexibility and adaptability of the model, content of feedback delivered, students’ characteristics and performance, tutors’ characteristics and self-perceptions, and supportive infrastructure.Conclusion: The model can be used as a reference for tutors to deliver constructive feedback during PBL tutorials. The challenges identified in using the constructive feedback model include the need for synchronized guidelines, ample time to adapt to the model, and skills training for tutors.
The Case for Systems Thinking in Undergraduate Engineering Education
Authors: Monat Jamie P. , Gannon Thomas F. , Amissah Matthew
Published: May 2022

Systems Thinking is currently a popular topic among the general public as well as in colleges and universities. Systems Thinking helps solve complex problems that cannot be solved using conventional means, helps engineers design functional and reliable systems, and helps to understand why the world looks and behaves as it does. However, Systems Thinking is usually not integrated into engineering curricula; instead, it is either taught as a stand-alone, independent program or course, or it is not taught at all. We believe that this is sub-optimal. Just as mathematics, physics, and computer science are integrated into engineering courses as fundamental tools, so should Systems Thinking be. Here we provide several examples demonstrating the application and benefits of Systems Thinking to a variety of engineering disciplines with the objective of convincing university administrators and instructors to integrate it into every engineering discipline.
Les pas d’armes et emprises d’armes dans la formation chevaleresque au xve siècle
Authors: Forster Loïs
Published: May 2022

Au xve siècle, les formes primitives de tournoi, livrées en pleine nature, avec des règles minimalistes et le même matériel que celui utilisé à la guerre, ont laissé place à des rencontres beaucoup plus codifiées : joutes, pas d’armes et emprises d’armes. Le but de cet article est de mesurer la place de ces rencontres dans la formation et la culture des hommes d’armes de la fin du Moyen Âge. Le matériel utilisé (parfois spécifiquement conçu pour ces rencontres), la façon de combattre et l’établissement de règles précises font-ils de ces jeux chevaleresques des simulacres de combats complètement artificiels ou permettent-ils, malgré l’importance accordée au cérémoniel et au décorum, de fournir aux chevaliers qui y prennent part une véritable expérience martiale et guerrière ? Nous chercherons à répondre à cette question à partir du cas du grand champion bourguignon Jacques de Lalaing.
La Maison militaire du roi
Authors: Masson Rémi
Published: May 2022

Au début du gouvernement personnel de Louis XIV, les troupes de la Maison du roi ne sont que des corps de gardes qui n’ont en commun que leur service domestique à la cour. Hétérogènes, ces unités se forgent progressivement une culture distincte du reste de l’armée. Cette culture se cristallise d’abord autour du service quotidien auprès de la personne du roi, puis surtout avec les transformations structurelles qui en font de véritables unités d’élite, dès la fin du xviie siècle. Aux yeux du reste de l’armée, la Maison militaire du roi semble alors faire preuve d’un esprit de corps d’autant plus fort qu’elle connaît une série de victoires retentissantes pendant la guerre de la ligue d’Augsbourg.Mais la culture de la Maison militaire se confond aussi avec la culture aristocratique de ses commandants. Ces derniers sont souvent des grands qui se disputent la faveur du roi. Leur influence est extrêmement forte à l’intérieur de compagnies qui ont elles-mêmes conservé une forte identité. Dans une institution où chaque unité possède un rang déterminé, la rivalité entre ces compagnies demeure exacerbée. Si cette dernière est un facteur d’émulation, elle est aussi une source de tension.Étudiée par le prisme de l’armée, l’émergence d’une culture de guerre propre à la Maison militaire est apparente. Mais du point de vue des unités qui la composent, cet esprit de corps se heurte à l’identité guerrière de chaque compagnie, qui résiste à se fondre dans une culture commune.
Le cadre juridique de l’action des casques bleus
Authors: Zašova Svetlana
Published: May 2022

La multiplication des opérations de maintien de la paix des Nations Unies depuis le début des années 1990 s’est accompagnée d’une diversification de leurs activités. Aux opérations de maintien de la paix stricto sensu s’ajoutent à présent des opérations de rétablissement de la paix, dans le cadre desquels le recours à la force a acquis une place fondamentale. Comparé à la diversité des missions confiées aux opérations de maintien de la paix des Nations Unies, le statut de leurs agents est quant à lui globalement resté homogène, présentant dès lors actuellement des ambiguïtés. Les agents du maintien de la paix – « agents civils » et « bérets bleus » – se divisent en outre en plusieurs catégories, en fonction de la nature de leur lien avec les Nations Unies ou avec leur État d’envoi, ce qui a des effets variables sur l’engagement de leur responsabilité individuelle. Le principe d’autonomie des Nations Unies a également entraîné des conséquences insatisfaisantes en termes d’engagement de la responsabilité des Nations Unies et des États d’envoi des forces pour les infractions commises par les agents du maintien de la paix, dans les ordres interne et international.
En puisant dans la pratique des Nations Unies et dans les jurisprudences nationales et internationales, cette étude se propose d’analyser le cadre juridique de l’action des casques bleus des Nations Unies sous un angle prospectif. L’étude propose ainsi l’adoption de réformes au sein du système onusien, et analyse les jurisprudences nationales et internationales en ayant à l’esprit la nécessaire conciliation entre les impératifs du maintien de la paix et le respect des droits de l’homme, tant ceux des agents du maintien de la paix, que ceux des individus potentiellement victimes de leurs actes.
Functional outcome of internal fixation of complex intraarticular fractures of the distal humerus (OTA-AO type-C) in focus of O’Driscoll criteria for optimized stability
Authors: Khamis Ahmed R. , Shoulah Saad A.
Published: May 2022

Introduction

tion Internal fixation of distal humeral fractures is challenging because of complex anatomy and articular or metaphyseal comminution. Bi-columnar locked plating (orthogonal or parallel) is the standard method of fixation the success of which requires a rigid stable construct to optimize stability. The aim of this retrospective study was to evaluate the outcome of fixation of type-C distal humeral fractures by orthogonal locked plates and to determine the causes of early mechanical failure according to O’Driscoll criteria of optimized fixation stability.

Settings and design

A retrospective study conducted in Benha University Hospital.

Patients and methods

A review of 34 patients with type-C distal humeral fractures fixed with orthogonal anatomical locking plates through the period from 2014 to 2019, and evaluation of their outcome after 24–36 months. Radiographic images were reviewed for O’Driscoll criteria of optimized fixation, and complications were recorded.

Results

Functional outcome was assessed with Mayo elbow performance score. Twenty patients had an excellent outcome, seven patients good and seven fair in whom, O’Driscoll criteria for optimized fixation stability were not met and fixation was revised. All patients showed radiological union of fractures after about 3 months from definitive fixation. Multivariate analysis of the collected data was done by SPSS software to determine the cumulative percent of its factors and its relation with the final outcome.

Conclusion

Internal fixation of type-C distal humeral fractures by anatomically precontoured locking plates must be optimized according to O’Driscoll criteria to avoid early mechanical failure, revision surgery, and to achieve satisfactory functional outcome.
Hemiarthroplasty vs. tripolar total hip arthroplasty in the treatment of displaced femoral neck fractures in old-age patients
Authors: Saleh Mohammed Rabie Abdalla , Nasser Anas Mansour Abdelfattah
Published: May 2022

Background

Displaced femoral neck fractures (DFNFs) are increasingly common in elderly patients. Hip arthroplasty, the recommended treatment of DFNF, consists of the total hip arthroplasty (THA) and hemiarthroplasty (HA). THA is superior to HA in younger patients. However, there are concerns whether the more substantial surgical trauma and higher dislocation rate would trade off the advantages of THA due to frailty and lower physical demands in the elderly over 75 years.

Objective

This study was designed to compare the clinical score, dislocation rate, and functional outcome between the dual mobility total hip replacement and the bipolar hemiarthroplasty (BHA) in the treatment of FNFs and which of them is more successful.

Patients and methods

A comparative randomized prospective study was conducted on 50 patients with DFNFs. All cases were operated upon in Helwan University Hospitals, divided them into two equal groups: the first group was treated by total hip replacement with a dual mobility cup (DMC) and the second group was treated by BHA. Full analysis of history detailed examination and primarily samples are taken during the period study from February 2020 to April 2021.

Results

There is a statistically significant improvement in modified Harris hip score (MHHS) in the last follow-up at 9 months later in favor to DMC group compared with BHA group (P<0.001). The postoperative MHHS in the last follow-up of DMC ranged from 68 to 92 with the mean of 85.96±5.47, whereas in BHA group, ranged from 60 to 89 with the mean of 78.04±8.40.

Conclusion

THA may be a preferred management option for active elderly patients over 75 years, which can provide superior hip function and life quality with acceptable risks. Strict management should be followed to prevent dislocation after a THA, especially within the first 6 months.
Early functional outcomes after medial meniscal posterior root tear repair
Authors: Seifeldin Ahmed F. , Abdelrazek Begad H.
Published: May 2022

Background

Meniscal root tears represent a functional loss; therefore, they greatly increase the risk of osteoarthritis. Root re-insertion aims to restore the anatomy and biomechanical function of the knee, reducing the risk of arthritis. Different techniques have been described. Preparation of the bed and instrumentation remains a challenge.

Aim

To demonstrate good early clinical outcomes after root re-insertion using accessory supra-meniscal portal, which helps both preparation and instrumentation of the bed.

Patients and methods

Between January 2019 and August 2019, we operated on 16 patients who met our inclusion criteria, having root tears of the medial meniscus. All patients underwent arthroscopic evaluation and re-insertion of the root tear medial meniscus using heavy braided suture material shuttled through a tibial tunnel and tied over a bone button. An accessory supra-meniscal portal was used to facilitate instrumentation and suture management. All patients were followed up for 2 years, and the Lysholm knee score was used for assessment at the final follow-up.

Results

A total of 16 patients were operated upon and followed up for a mean of 24 months. The mean Lysholm score improved from 73.5±12.61 preoperatively to 93.75±6.90 postoperatively, with a P value of 0.001. The mean preoperative and postoperative Lysholm scores were higher for the traumatic tears as compared with degenerative tears. Older patients showed lower functional outcomes.

Conclusion

Root re-insertion helps restore knee function and biomechanics, thereby prevents detrimental arthritis. Younger patients and those who have sustained traumatic injuries are more likely to improve as compared with elder patients and degenerative tears.

Published: May 2022

A previous meta-analysis, entitled “The association between metabolic syndrome and bladder cancer susceptibility and prognosis: an updated comprehensive evidence synthesis of 95 observational studies involving 97,795,299 subjects,” focused on all observational studies, whereas in the present meta-analysis, we focused on cohort studies to obtain more accurate and stronger evidence to evaluate the association between metabolic syndrome and its components with bladder cancer. PubMed, Embase, Scopus, and Web of Science were searched to identify studies on the association between metabolic syndrome and its components with bladder cancer from January 1, 2000 through May 23, 2021. The pooled relative risk (RR) and 95% confidence intervals (CI) were used to measure this relationship using a random-effects meta-analytic model. Quality appraisal was undertaken using the Newcastle-Ottawa Scale. In total, 56 studies were included. A statistically significant relationship was found between metabolic syndrome and bladder cancer 1.09 (95% CI, 1.02 to 1.17), and there was evidence of moderate heterogeneity among these studies. Our findings also indicated statistically significant relationships between diabetes (RR, 1.23; 95% CI, 1.16 to 1.31) and hypertension (RR, 1.07; 95% CI, 1.01 to 1.13) with bladder cancer, but obesity and overweight did not present a statistically significant relationship with bladder cancer. We found no evidence of publication bias. Our analysis demonstrated statistically significant relationships between metabolic syndrome and the risk of bladder cancer. Furthermore, diabetes and hypertension were associated with the risk of bladder cancer.

This research discusses a comparative study between the educational concepts of John Dewey and Cornelius Van Til to find a concept of education that teaches children not only to achieve intellectual intelligence but also to shape the child's character and make the child a person who fears God. This research uses a qualitative method, a literature study research approach (library). Based on the results of the research, the author makes a curriculum design that tends to Van Til's concept of education because in the idea of education according to Van Til, he emphasizes education based on God's Word, which is the basis for building human character and making children as individuals who are not only intellectually intelligent but also intellectually intelligent. The results of this research indicate that there is a sharp difference between the views of John Dewey and Cornelius Van Til regarding education. John Dewey focused education on human intelligence alone. Education must introduce children to who their Creator is so that children live responsibly towards their Creator. Education that intervenes in faith, education that applies Bible integration teaches children moral values ​​and character to become God-fearing individual’s fear of God.
Down-step statistics in generalized Dyck paths

Published: May 2022

The number of down-steps between pairs of up-steps in $k_t$-Dyck paths, a
generalization of Dyck paths consisting of steps $\{(1, k), (1, -1)\}$ such
that the path stays (weakly) above the line $y=-t$, is studied. Results are
proved bijectively and by means of generating functions, and lead to several
interesting identities as well as links to other combinatorial structures. In
particular, there is a connection between $k_t$-Dyck paths and perforation
patterns for punctured convolutional codes (binary matrices) used in coding
theory. Surprisingly, upon restriction to usual Dyck paths this yields a new
combinatorial interpretation of Catalan numbers.
Environmental Geochemistry and Bioavailability and Health Effects of Chromium in Topsoil and Cauliflower Plant in Kirkuk, Northern Iraq
Authors: Al-Faili Jaafar
Published: May 2022

The content of chromium in the surface soil as well as its content in cauliflower plants in Kirkuk was studied to investigate the environmental geochemistry of this element. 30 samples of surface soil were collected from inside the study area at a depth of 0-20 cm. Eight samples of cauliflower were collected from the same study area, soil and plant sampling sites were determined using a GPS device . Using ICP-MS technology we were able to analyze these samples. The results of ICP-MS showed that the average concentration of chromium in the soil samples was 78.59 mg/kg and its highest concentration was in the sample A12 (93.4 mg/kg), the increase in the concentration of chromium in the soil is due to agricultural fertilizers, irrigation with sewage water, the impact of traffic, commercial activities and industrial workshop. The mean of its concentration cauliflower samples was 3.81 mg/kg, and the highest concentration was 4.7 mg/kg in sample AQ10, the increase in the concentration of chromium in the plant is due to pollution in the soil, and the difference in these concentrations is due to the location of the sample and the properties of the soil. The plant absorbs it through the roots, then the stems, leaves,and fruits. Bioaccumulation factor value for chromium ranged with an average of 0.047 for all cauliflower samples. CF soil samples that the surface soil for this area is within a level (low pollution, CF <1) indicating the presence of pollution at a very low level, and the potential ecological risk index PRI found that all surface soil samples in the study area have (low risk level, PLI≤50), and Igeo indicates that there is no pollution (practically uncontaminated, Igeo ≤ 0). It was found that the value of THQnc for both groups of adults and children in the study area was greater than 1. The CRcancer values for both groups were greater than 1*10-4.
Geo-Engineering Analysis and Evaluation of Unstable Rocky Slopes near Shaqlawa, NE Iraq
Authors: Al-Samarrai Thair
Published: May 2022

Engineering Geological study of rock slope stability was conducted in two stations along the Shaqlawa region route. Rock slopes and discontinuities were thoroughly investigated at each site, and the linkages between failures were identified. The marly limestone rocks were defined in engineering terms, and rockfall and rolling were the sorts of failures seen during the field investigation. Slope angle and height, stratum dip, differential weathering and erosion, and discontinuities were all identified as variables impacting slope stability in the research region. The compressive strength of the rock for the research region ranges between 96.31–109.87 according to laboratory testing of rock samples (Point –load test). MPa. When the Bejerman (1998) Landslide Possibility Index classification is used in the study region, it reveals that the slope in the first station is in category VI of the very high Landslide Possibility Index and the slope in the second station is in category V of high Landslide Possibility Index. Both stations have a high level of risk associated with the Landslide Possibility Index. Slopes might benefit from some remedial actions, such as the removal of unstable stones and the installation of retaining walls, to prevent further failures and protect the slopes in the future.
Tratamiento de la fisura anal crónica. Resultados alejados de las anoplastias.
Authors: Jüül Agustina , Villaggi Javier Ignacio , Quijano César Eugenio
Published: May 2022

INTRODUCCION: La fisura anal es un desgarro de la mucosa anal ectodérmica. Se manifiesta con intenso dolor local y es una afección frecuente, aunque sub-diagnosticada. Su presentación puede ser aguda, y cicatrizar con un adecuado tratamiento médico, pero si no es bien instituido puede evolucionar y conformar el complejo fisurario anal crónico. Sus causas más importantes son las heces gruesas y duras, así como otros traumas anales. La hipertonía esfinteriana podría ser la causa o consecuencia del trauma, produciendo además isquemia local que dificulta la cicatrización.

DISEÑO: Se realizó un estudio retrospectivo y descriptivo de 168 pacientes con fisura anal crónica primaria operados entre 2010 y 2018 mediante colgajo cutáneo deslizado a pedículo subcutáneo.

MATERIAL Y METODOS: A todos se les indicó preparación mecánica. Se sometieron a anestesia general y se acomodaron en posición de navaja sevillana. Se realizó la fisurectomía previa identificación del esfínter anal el cual se respeta, y se talló colgajo cutáneo a pedículo subcutáneo que se deslizó y ancló a la línea pectínea con surget de vicryl 5-0.

RESULTADOS: El 58,33% fueron del sexo femenino y el 41,66% masculino, con un rango etario entre 28 y 72 años. Se indicó analgesia post-operatoria, y luego del alta el 85% no requirió rescate analgésico. Ningún paciente refirió dolor horrible o extremo. El tiempo de cicatrización tuvo un rango de 4 a 8 semanas. No se presentó recidiva o persistencia de la fisura.

CONCLUSIONES: Los pacientes con fisura anal crónica pueden tratarse con colgajo de piel anal a pedículo subcutáneo con buenos resultados. La anoplastia es una técnica simple, reproducible, bien tolerada, que no causa trastorno de la continencia fecal y presenta altas tasas de curación y satisfacción a largo plazo. Por lo expuesto debería ser considerada la técnica de elección en el tratamiento de la fisura anal crónica.
EXPLORING THE POTENTIAL PARASITIC PATHOGENS CAUSING DIARRHEAL DEATH TO YAK CALVES WITH BLOODY EXCREMENT THROUGH HIGH-THROUGHPUT SEQUENCING
Authors: Li Kun
Published: May 2022

Yaks are of great importance on the high plateau. However, a serious diarrhea disease has emerged in the past few years causing a catastrophic threat to the yak industry. The current study was carried out to explore the parasitic pathogens in involved in diarrheal death of yaks with bloody excrement from Sichuan, China. A total of 12 fresh fecal samples were obtained from 6 healthy yak calves (H group), and 6 yak calves that died from acute bloody diarrheal (B group). High-throughput sequencing was utilized to compare the parasite burden between the H and B yak groups. At phylum level, Amoebozoa (P<0.0001), Apicomplexa (P<0.0001) and Blastocysta (P<0.0001) was discovered to be obviously higher in B yaks, respectively. On the other hand, Loukozoa (P<0.0001) and Parabasalia (P<0.0001) were both found to be significantly higher in H yaks. At genus level, Entamoeba (P<0.0001), Theileria (P<0.001), Tetratrichomonas (P<0.01), Blastocystis (P<0.0001), and Cryptosporidium (P<0.0001) were found to be predominantly higher in B yaks, while Simplicimonas (P<0.0001), Hypotrichomonas (P<0.0001), and Gregarina (P<0.01) were higher in H yaks. In conclusion, the current research herein revealed the genus of Entamoeba, Theileria, Tetratrichomonas, Blastocystis, and Cryptosporidium as potential parasitic pathogens causing the serious emerging bloody diarrheal deaths in yaks on plateau. Our present results provide insightful knowledge that can be important in controlling and preventing diarrhea in bovine animals.
