FROM POINT CLOUD TO CAD-MODEL BASED ON AI
Authors: Luetzenberger J , Grau M , Stjepandic J , Zerbst C
Published: October 2022

Most vessels undergo modernization and overhaul during their lifecycle. A model representing the as-is status is a prerequite to plan these activities. Especially when it comes to overhauling a piping system, it is crucial to know their exact spatial layout. Otherwise, the existing parts and the newly delivered parts may not fit together.

Capturing the surfaces of the parts using a 3D scanner and generating a point cloud representing the as-is situation is state of the art. The point cloud is then loaded into a CAD system to represent the existing parts before designing the new parts
and ensure they fit together seamlessly. This requires remodelling at least the connection points of the existing parts manually. Remodelling is both time-consuming as well as error-prone, so we’d like to avoid it.

In the DigiTwin research project [1], we developed a solution for this. It features a fully automatic generation of a CAD model based on recognizing piping components from the point cloud using artificial intelligence. The main task is running object recognition from the point cloud. It is crucial to find the correct components and detect their position. Based on that, we generate native CAD models for typical shipbuilding tools. This enables using the automatically generated CAD models for the as-is status as reference geometry for the updated design. In our paper, we’d like to present the steps needed to do so and also the result we achieved.

Authors: Taniguchi T , Morishita M , Matsuo K
Published: October 2022

Data integration has become an important issue to develop complex products in shipbuilding. This paper introduces a development of a prototype system for PLM systems in shipbuilding. The PLM system is developed for the purpose of precise production planning and the production management in the shop floor. Especially, the PLM system is considered as a use case to provide input data which is necessary for production simulators that reproduce precise work procedures at the shop floor. The data structure in the PLM system is reviewed to provide the necessary data to the production simulator in the beginning of this paper. The data is represented as BOM (Bill of Materials) and BOP (Bill of Process), which are associated with product information, process information, and facility information, and is implemented in the PLM system. The data flow from the PLM system to the production simulator is introduced, then a series of demonstrations from the PLM system to the execution of the production simulator are presented, followed by a discussion of the effects and the future issues of the proposed data structure and the PLM system.
DEVELOPMENT OF A PIPE FABRICATION PROCESS DETERMINATION SYSTEM USING GRAPH DATABASE AND PROCESS SIMULATION
Authors: Mihara Y , Mitsuyuki T
Published: October 2022

As the importance of piping in shipbuilding increases, streamlining pipe fabrication processes has become one of the most critical issues. However, since pipe fabrication processes are complicated, it has not been adequately digitized and modeled.
This paper proposed a system to automatically determine the pipe fabrication process considering the design of the target pipe and various information in a factory. In the developed system, tasks are generated using the information on the parts,
and these relationships are registered in a graph database. This system also generates all conceivable fabrication processes by allocating workplaces to each extracted task. The optimal fabrication process is selected by executing the production simulation using each fabrication process which is generated from the information on the graph database and target factory. We will also show the result that the developed system is applied to three virtual pipe fabrication factories.
ABOUT USING THE GAME ENGINES IN SHIPBUILDING, SOFTWARE DEVELOPER’S PERSPECTIVE
Authors: Sikic G
Published: October 2022

During the development of the ShipExplorer[1][2] suit of the programs, every single detail was carefully designed and implemented using low level libraries like OpenGL. The result was very sophisticated, quality program that delivered top performance with wonderful user experience. However, development of new features required theoretical and practical knowledge about many different disciplines starting from linear algebra, knowledge of OpenGL internals, and proficiency in C++ programming language. The additional problem was that every new hardware target, like mobile phones, or various
HMD models had to be addressed particularly, without any code sharing.
At the same time, new class of programs started appearing, so-called “Game Engine”[3] programs. This class of programs promised maximum results with a minimum effort. Screenshots with spectacular graphics and pre-generated movies were available, showing the output of these programs. Also, “out of the box” support for all major platforms and various hardware was claimed. Taken together, it was enough to rise a question if approach of using low level libraries was a correct approach in the presence of the tools like “Unreal Engine” or “Unity”.
In this paper, author’s experience in working and extending Unreal Engine, will be presented. Problems using C++ programming language and internal “Blueprint” visual scripting in Unreal Engine will be analyzed. Scenario of usage as a visualization and annotation tool will be evaluated and compared to the possible alternative approaches.
De la communauté d’hier à la communauté d’aujourd’hui : continuités andines
Authors: Chagnollaud Fanny
Published: October 2022

Terrain de prédilection des ethnologues qui ont travaillé dans la région, la communauté a longtemps constitué l’objet central de l’anthropologie andine et a été au cœur des grands débats théoriques de la discipline. De la construction d’un modèle idéel à sa déconstruction, nous suivrons dans cet article les réflexions théoriques qui ont tenté de définir et de comprendre cette entité sociale fondamentale du monde andin. Nous chercherons ensuite à montrer l’état actuel de ces réflexions en nous appuyant tout particulièrement sur les apports récents d’une anthropologie andine urbaine encore trop peu développée mais indispensable à la compréhension des sociétés andines contemporaines.
Fabricants d’instruments et commissaires de la République : une étude du personnel de la section de physique de la Commission temporaire des arts
Authors: Guillaume Vincent
Published: October 2022

Cet article étudie le travail des membres de la section de physique de la Commission temporaire des arts qui, entre 1793 et 1795, inventorient les instruments de physique saisis à Paris aux ennemis de la République. La constitution de collections nationales de physique est une opération progressive initiée par le gouvernement révolutionnaire à partir de l’été 1793, après la fermeture de l’Académie des sciences et l’augmentation des saisies révolutionnaires. Les instruments sont alors inventoriés et regroupés dans le dépôt national de physique créé en juin 1794. La section de physique de la Commission temporaire se compose du démonstrateur Charles et de trois artistes, les fabricants d’instruments Fortin et Lenoir et l’horloger Janvier. La nomination d’artistes dans une commission publique est une étape supplémentaire dans la reconnaissance de leur rôle dans la production et la transmission de savoirs ainsi que dans le rapprochement entre fabricants d’instruments et État révolutionnaire.

Published: October 2022

Background. The COVID-19 pandemic resulted in a nationwide lockdown in South Africa, initiating a shift in society’s interaction to the online space. Students therefore became reliant on electronic devices for learning.Objective. The study aimed to investigate the prevalence of digital eye strain (DES) in a university student population during the nationwide COVID-19 lockdown in South Africa.Methods. Randomly sampled 290 university students were surveyed online about their screen time and DES during lockdown. The survey included a validated screen time questionnaire to measure screen time in hours per day and a validated computer vision syndrome questionnaire (CVS-Q) to measure the frequency and intensity of symptoms during edevice use (s). Descriptive statistics were used to analyze CVS-Q scores and screen time.Results. The mean (SD) age of the sample was 21.04   2.32 years. Of these, 82.41% used smartphone devices and 55.52% of the participants did not use any optical correction. The prevalence of DES during COVID-19 lockdown in 2020 was 64.24%. Screen time on an average weekday and over the weekend, as a primary activity, had a median of 13 hours per day during lockdown.Conclusion. The high prevalence of digital eye strain may be a harbinger of a decrease in student performance. Creating awareness of proper visual hygiene amongst students is paramount in decreasing the high prevalence of DES.
Knowledge, attitudes and practices towards lung cancer among adults in KwaZulu-Natal, South Africa: a cross-sectional survey
Authors: Dlamini S. B. , Sartorius B. , Ginindza T. G.
Published: October 2022

Background.  Lung cancer remains the number one cause of cancer mortality estimated at 1.8 million deaths. There are limited studies in resource poor countries regarding knowledge, attitudes and practices towards lung cancer.Objective. This study aimed to describe the knowledge, attitudes and practices regarding lung cancer in selected communities in KwaZulu-Natal, South Africa. Methods. An observational, analytic cross-sectional study design was conducted using a standardized questionnaire. A stratified random cluster sampling method was applied across five communities. A regression model was developed to identify the predictors of the level of knowledge.Results. About 59.9% (95% CI 52.0 - 67.3) of the participants reported to have heard of lung cancer. The mean knowledge score was 41.8% (95% CI 35.7 - 47.9%). Coughing blood was the most recognized symptom (61.0%, 95% CI 52.1 - 69.1). About 17% (95% CI 14.7 - 21.5) of participants reported to be smokers. Many respondents reported that they would go to a health centre or clinic in case they were coughing blood (72.4%, 95% CI 93.9 - 79.5). Less than 10% (95% CI 3.9 - 8.1) of participants was screened for lung cancer at the time. Gender, history of working in the chemicals industry, screening for lung cancer, and time taken to seek health care when sick were significant predictors of lung cancer knowledge.Conclusions.  Public health interventions should be explored to increase the levels of community awareness regarding lung cancer, particularly focusing on the importance of screening, early diagnosis and treatment.
Resolution of daytime and night-time respiratory symptoms but persistent sleep apnea in severe asthma with the add-on of benralizumab
Authors: Tondo Pasquale , Fanfulla Francesco
Published: October 2022

Introduction: The relationship between asthma and obstructive sleep apnea (OSA) is a widely debated topic in the scientific literature with the controversy surrounding the bi-directional nature of the correlation.Case presentation: We report the case of a 59-year-old male being affected by severe allergic eosinophilic asthma and severe OSA (apnea-hypopnea index [AHI] 32 ev·hr-1).  Due to a clinical worsening of asthma (aggravation of dyspnea, chest constriction and night-time respiratory symptoms), despite the optimal therapy for asthma and recurrent administration of systemic corticosteroids, we have added-on treatment with benralizumab (monoclonal anti-interleukin 5 antibody). After eight months, the patient reported an improvement in asthma control (asthma control test [ACT]= 25 points), in pulmonary function and a good control of nocturnal symptoms of both diseases (i.e., wheezing, snoring, etc.). Then, the follow-up polysomnography (PSG) was performed resulting in a high reduction of OSA severity (~18% AHI) even if obstructive events persisted and almost resolution of nocturnal hypoxemia. So, a trial with positive airway pressure (PAP) was proposed to the patient, who declined.Conclusions: In consideration of our experience, we suggest that the nocturnal profile of patients with severe asthma should be always studied by a sleep investigation to prevent the negative effects of interaction with OSA. However, further studies on larger samples are needed to better understand the pathophysiological mechanisms underlying the beneficial effects of benralizumab on obstructive events during sleep.

Authors: Parveen Shadman , Bhatnagar Kavita , Singh Pratibha , Meena Seema , Suman Suwarna , Shiromani Sakshi
Published: October 2022

PURPOSE:

The purpose of this study was to compare ganglion cell complex and peripapillary retinal nerve fiber layer (RNFL) thickness between pregnant females with gestational diabetes mellitus (GDM) and healthy pregnant females.

MATERIALS AND METHODS:

This was a single-center, prospective, analytical cross-sectional study including pregnant females with a gestational age of 24 weeks or more in the GDM and control groups. The GDM group included 162 pregnant females with GDM, and the control group included 162 healthy pregnant females. Peripapillary RNFL (pRNFL), macular RNFL (mRNFL), GCL+ (ganglion cell layer [GCL] + inner plexiform layer [IPL]), and GCL++ (mRNFL + GCL + IPL) thickness were analyzed using spectral-domain optical coherence tomography (OCT), and comparisons were made between the groups.

RESULTS:

Both the groups had similar mean age (P = 0.219), intraocular pressure (P = 0.186), central corneal thickness (P = 0.689), Schirmer test value (P = 0.931), and tear breakup time (P = 0.651). The mean pRNFL thickness of the GDM and control groups was 100.75 ± 8.36 μm and 106.77 ± 8.44 μm (P < 0.0001). pRNFL was significantly thinner in all four quadrants (P < 0.05) in the GDM compared to the control group. We observed that the mean mRNFL, GCL+, and GCL++ thickness were significantly reduced in GDM in comparison to the control group (P < 0.05).

CONCLUSION:

Our study showed that OCT plays an indispensable role in determining initial retinal changes caused by GDM before the development of diabetic retinopathy.
Diagnostic and interventional EUS in hepatology: An updated review
Authors: Jearth Vaneet , Sundaram Sridhar , Rana Surinder Singh
Published: October 2022

EUS has become an increasingly used diagnostic and therapeutic modality in the armamentarium of endoscopists. With ever-expanding indications, EUS is being used in patients with liver disease, for both diagnosis and therapy. EUS is playing an important role in providing additional important information to that provided by cross-sectional imaging modalities such as computerized tomography and magnetic resonance imaging. Domains of therapy that were largely restricted to interventional radiologists have become accessible to endosonologists. From liver biopsy and sampling of liver lesions to ablative therapy for liver lesions and vascular interventions for varices, there is increased use of EUS in patients with liver disease. In this review, we discuss the various diagnostic and therapeutic applications of EUS in patients with various liver diseases.
Successful Management of a Cutaneous Abscess Caused by Candida Albicans in a Very Low Birth Weight Neonate
Authors: Vaddi Vamsi Krishna , Goyal Medha , Mascarenhas Dwayne , Haribalakrishna Anitha
Published: October 2022

Fungal sepsis is a sinister infection in the neonatal intensive care unit associated with significant mortality and neurodevelopment sequelae. Very low birth weight and very preterm neonates are often predisposed and manifestations range from mucocutaneous to invasive organ involvement. Prompt recognition and treatment with appropriate antifungal improve survival and neurodevelopmental outcomes. In this report, we describe a neonate with rare dermatological manifestation in the form of a cutaneous fungal abscess with urinary tract involvement. The diagnosis was based on budding yeast cells seen on pus smear examination and culture suggestive of Candida albicans. Risk factors included birth weight <1500 g, placement of central vascular catheter, endotracheal tube, parenteral nutrition, surgical intervention, and use of broad-spectrum antibiotics. Amphotericin B deoxycholate and incision and drainage of the abscess were done to manage the abscess successfully. This report highlights the consideration of Candida as an etiological agent for cutaneous abscesses, in case of preterms with risk factors for fungal infection. Evaluation for systemic dissemination is mandatory and management with appropriate antifungal agents is critical for survival.

Authors: Panale Prashant , Jamal Ahmed Zaid , Bhat Vivek , Thergaonkar Ranjeet Wishram
Published: October 2022

A 65-day-old female infant, born to a third-degree consanguineously married couple, was brought to us with neonatal cholestasis and technetium-99 m hepatobiliary iminodiacetic acid scan reporting nonvisualization of the tracer activity in the intestine after 24 h. The neonate had ichthyosis and mild flexion contractures at elbows and knees. Ultrasonography and magnetic resonance cholangiopancreatography did not reveal any evidence of biliary atresia. Liver biopsy showed preserved liver and portal triad architecture with sinusoidal dilatation, giant cell formation, and biliary stasis. The neonate had an episode of enterocolitis complicated by acute kidney injury with persistent renal tubular dysfunction on recovery. Genetic testing revealed a homozygous pathogenic variant c. 201C > A (p. Tyr67Ter) in VPS33B. A diagnosis of arthrogryposis, renal dysfunction, and cholestasis (ARC) syndrome was made, and the neonate managed conservatively with counseling of parents regarding poor prognosis. The neonate died of an intercurrent illness at the age of 7 months. This is possibly the fourth case of ARC syndrome reported from India.

Authors: Hashmi Syed Asif , Aggrawal Monika , Pandey Rahul , Gulati Deepika , Khan Inam Danish
Published: October 2022

Introduction:

Thyroid swellings are one of the most commonly encountered lesions with most of the thyroid swellings being benign. The cancerous lesions of the thyroid also present as nodules or masses and pose a diagnostic challenge. The thyroid cytology reporting system has been inconsistent with the use of various terminologies. The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) was introduced in 2007 to bring about uniformity in reporting of thyroid lesions.

Aim:

This study aimed to compare conventional reporting with TBSRTC.

Materials and Methods:

A retrospective study was done in which 6 years of data were retrieved. Cytology slides were reviewed and categorized as per the TBSRTC and compared with other studies.

Results:

There were numerous categories in the conventional thyroid fine-needle aspiration cytology reporting system which has been reduced to six categories in TBSRTC. TBSRTC has also streamlined the reporting removing the confusion among cytologists and clinicians.

Conclusion:

TBSRTC is consistent and reproducible and should be used as a standard method of reporting.
Fourier integrator for periodic NLS: low regularity estimates via discrete Bourgain spaces
Authors: Ostermann Alexander , Rousset Frédéric , Schratz Katharina
Published: October 2022

In this paper, we propose a new scheme for the integration of the periodic nonlinear Schrödinger equation and rigorously prove convergence rates at low regularity. The new integrator has decisive advantages over standard schemes at low regularity. In particular, it is able to handle initial data in

H^s

for

0 < s\le 1

. The key feature of the integrator is its ability to distinguish between low and medium frequencies in the solution and to treat them differently in the discretization. This new approach requires a well-balanced filtering procedure which is carried out in Fourier space. The convergence analysis of the proposed scheme is based on discrete (in time) Bourgain space estimates which we introduce in this paper. A numerical experiment illustrates the superiority of the new integrator over standard schemes for rough initial data.
A non-linear version of Bourgain’s projection theorem
Authors: Shmerkin Pablo
Published: October 2022

We prove a version of Bourgain’s projection theorem for parametrized families of

C^2

maps, which refines the original statement even in the linear case by requiring non-concentration only at a single natural scale. As one application, we show that if

A

is a Borel set of Hausdorff dimension close to

1

in

\mathbb{R}^2

or close to

3/2

in

\mathbb{R}^3

, then for

y\in A

outside of a very sparse set, the pinned distance set

\{|x-y|:x\in A\}

has Hausdorff dimension at least

1/2+c

, where

c

is universal. Furthermore, the same holds if the distances are taken with respect to a

C^2

norm of positive Gaussian curvature. As further applications, we obtain new bounds on the dimensions of spherical projections, and an improvement over the trivial estimate for incidences between

\delta

-balls and

\delta

-neighborhoods of curves in the plane, under fairly general assumptions. The proofs depend on a new multiscale decomposition of measures into “Frostman pieces” that may be of independent interest.
The role of ‘standard economic theory’ and the pass on defence in competition law-related litigation
Authors: Ward William
Published: October 2022

It is typical in competition law-related litigation for damages claims to be brought by companies who have been overcharged for a product or service. A standard defence is that the claimants passed on the overcharge to buyers of their own products and services, thus reducing or eliminating their losses. Typically, ‘standard economic theory’ is cited to support this argument. However, standard economic theory offers no universal prediction for how firms will respond to a cost increase. Instead, economic theory says that the extent of pass on is dictated by a range of internal and external factors, ultimately implying a whole spectrum of possible rates of pass on.

Published: October 2022

The spread of antibiotic resistance genes (ARGs) caused by biofilm growth in drinking water distribution systems (DWDSs) poses a serious threat to human health. The influence of disinfection by-products (DBPs) on the distribution of ARGs and mobile genetic elements (MGEs) in different phases (biofilms and water) of DWDSs is unclear. In this study, the characteristics of microbial indices, trihalomethanes (THMs), haloacetic acids (HAAs), ARGs and MGEs in biofilms and effluents of simulated DWDS reactors were detected during 150 d of operation. During the mature biofilm periods of 90 d or 120 d, for both biofilms and effluents, seven categories of ARGs (except tetracycline) and MGEs were at their highest and lowest relative abundance in the entire operation cycle, respectively. The influence of DBPs on ARGs and MGEs in the DWDS was different in different phases. In effluents, DBPs showed a stronger relationship with ARGs compared with MGEs. THMs and HAAs had positive correlations with various ARGs, which indicated that DBPs affected the distribution of resistance genes. In biofilms, the influence of MGEs on ARGs was stronger than that of DBPs on ARGs. Thus, DBPs might be an important contributor to the enrichment and spread of ARGs in water.

Authors:   Chemical Engineering, College of Engineering, University of Bahrain, P. O. Box: 32038, Kingdom of Bahrain, Ghassoul Mostefa
Published: October 2022

Flow meters are extremely important in industry. There are many types of flow meters. One of them is one based on Hall effect whose output is modulated square wave which is difficult if not impossible to be caught by most the digital controllers such as DCS, PLC and alike. This paper presents an electronic interface which addresses this problem where it could solve any analog interface almost to any digital controller. The design first signal conditioned the output of the Hall effect sensor, then converts it into voltage which is also signal conditioned to limit the output in the range of 0-5V for 55-550Hz input (1-10L/min). This signal is then converted to 4-20mA current which could easily be read by any digital controller such as PLC, DCS, RTU. Keywords—Flow meter, Hall effect, frequency to voltage converter, voltage current converter

Published: October 2022

Introducción. No todas las personas expuestas al COVID-19 desarrollan una enfermedad respiratoria grave y el número de personas adultas jóvenes sin patologías previas, afectadas gravemente por el virus, viene en aumento. Se ha evidenciado un gran número de síntomas inespecíficos y complicaciones, posterior a la recuperación.
Objetivo. Evaluar las repercusiones en un sujeto sano y físicamente activo que presentó complicaciones médicas graves y complicaciones posteriores al COVID-19.
Reporte de caso. Hombre de 41 años de edad, físicamente activo y sin enfermedades conocidas, en quien se documenta infección por SARS-CoV2 con prueba PCR positiva. Requirió 22 días en UCI, 17 días en hospitalización general, 57 días de incapacidad y posterior a doce meses presenta perdida evidente de peso, pérdida de memoria, dificultad para pensar y concentrarse, pérdida de masa muscular, compromiso de la función hepática, cansancio y fatiga, dolor muscular, problemas para dormir, cambios en el estado de ánimo y alteraciones del gusto. De acuerdo con los actuales hallazgos, la producción de un tipo de anticuerpo impide que el sistema inmune tenga una respuesta adecuada contra la enfermedad. Sumado a esto, se ha descrito una nueva puerta de entrada del virus en el organismo: la proteína neuropilina-1 (NRP1), además de la posible disminución del surfactante que permite la flexibilidad de los pulmones. Lo anterior podría dar respuestas a las complicaciones en personas sanas y físicamente activas posterior a la infección por COVID-19.
Conclusiones: Entendiendo que el COVID-19 es una enfermedad reciente, aún hay mucha información por recolectar para así entender su comportamiento en el cuerpo humano. Sin embargo, las investigaciones van dando evidencia del porqué el COVID-19 puede generar graves complicaciones médicas en personas sanas y físicamente activas. Son necesarias más investigaciones con esta población, para así realizar planteamientos de manejo clínico acordes a la enfermedad y evitar desenlaces fatales.

Genetic variation determinations among micro-propagated plants is often tested to prevent the occurrence of morphological abnormalities which are deemed unsuitable for commercial use. Although the MD2 pineapple has been widely propagated clonally, there is no genetic fidelity testing on the micro-propagated MD2 pineapple. This study aims to determine genetic variations among the micro-propagated MD2 pineapples using Randomly amplified polymorphic DNA (RAPD) and inter simple sequence repeats (ISSR) markers. The amplification of both markers across 22 pineapple genotypes generated 120 bands with polymorphism percentages of between 93% and 73%, respectively. The evaluation through Rp, PIC and MI showed RAPD more informative (Rp = 7.08, PIC = 0.34, MI = 1.72) compared to ISSR (Rp = 4.17, PIC = 0.32, MI = 1.00). The PCA resulted in indefinite clustering patterns while the dendrograms portray the inability of the markers to correlate the plant morphology with their genetic structure. An analysis of molecular variance (AMOVA) analysis found high genetic variation (>70%) within the pineapples under review. Meanwhile, the Phi statistic estimate showed a wide genetic variation among the studied genotypes. To conclude, both markers suggest that the plant morphology did not inevitably correlate to its genetic structure. This study may form the basis for the MD2 breeding programme and explore other molecular markers that can potentially correspond to phenotypic polymorphisms.
Armenian Statehood in Foreign Policy Realities: the First Steps of the First Republic
Authors: Petrosyan Gegham
Published: October 2022

The article analyzes the prerequisites for the establishment of the restored Armenian statehood in Eastern Armenia at the end of May 1918, as well as from June to November, which was of existential importance for the further development of the Republic of Armenia. The establishment of Armenian statehood took place under extremely difficult internal and external conditions. The problems facing the newly created Republic of Armenia and requiring immediate solution were diverse and many. In unprecedented geopolitical conditions, the political elite is faced with a national agenda to bring the state institutions and the Armenian society out of a hopeless situation. For the implementation of which political will, enormous efforts and consistent work were always needed.
The article also analyzes the problems related to social security, because hunger, epidemics and various diseases continued to negatively affect all spheres of Armenian society’s life. It was obvious that the genocidal policy was continued against the Armenian people, because being isolated from the civilized world, helpless and surrounded by enemies, Armenia was quickly running out of food supplies.
The moral and psychological atmosphere prevailing in the Armenian society is also in the center of attention in the article. The latter generated despair and internal division, which gradually destroyed the united spirit of the nation, weakened resistance, and deprived the ability to think and act for the common good of the state. In such circumstances, the establishment of Armenian statehood was extremely difficult. The disastrous internal political and economic situation of the republic continued until the end of the year, one of the main reasons of which was the security and hostile environment of Armenia.
Erdogan against Turkey։ Stalemate of “Patriot-F-35-S-400” triangle
Authors: Gabrielyan Hayk
Published: October 2022

After the attempted military coup in 2016, Turkey began to show interest in the Russian S-400 systems, and initially there was an impression that Turkey was only bluffing, was simply using Russia in its relations with the United States (as it had previously done with China (CPMIEC) in the same matter) and was seeking to show the US that it had an alternative (S-400). However, Turkey showed its persistence, and was able to buy these systems quite quickly, despite the fact that the United States strongly opposed it. In this context, this study aims to clarify the main reasons for Turkey's persistence on this issue, taking into account the personal factor of Erdogan. 
The article also analyzes the authoritarian strengthening of militarism and Erdogan’s personal factor for buying the S-400, who was the beneficiary of buying the S-400 systems. This article shows that sometimes Erdogan’s personal interests and Turkey’s state interests should be separated from each other, that in some cases Erdogan’s personal interests and Turkey’s state interests may or may not coincide partially or completely․ It is emphasized that in each case of conflict of interests, Erdogan’s personal interests prevail, that the problems should be examined first of all from the perspective of Erdogan’s personal interests and not from Turkey’s state interests, otherwise many things remain unclear and unexplained.
Focusing on Turkey’s purchase of the S-400 systems, this study also asks why NATO member Turkey even after the purchase has not given up those Russian systems and why it still continues to persist․ The topic is also actual for Armenia, as it is related to the sphere of the Turkish Air Force and the defense capability of Turkey in general, its prospects. The article describes the brief history of Turkey’s purchase of S-400 systems, analyzes the motives of that move from territorial, temporal, cause-and-effect, and other perspectives, and presents Turkey’s attempts to get out of the existing situation. This study aims to identify the main trends underlying the conflict between Erdogan and the Turkish political elite over the purchase of the S-400.

Published: October 2022

Kebisingan dapat berdampak pada berbagai gangguan kesehatan sehingga perlu dilakukan pengendalian kebisingan, salah satunya menggunakan media peredam tanaman. Tujuan penelitian ini adalah untuk mengetahui efisiensi penurunan tingkat kebisingan oleh media peredam tanaman pucuk merah dan asoka. Pengukuran dilakukan sebanyak 2 kali ulangan menggunakan sumber suara berupa speaker yang diletakkan di dalam kotak. Pengambilan data setiap 5 detik selama 10 menit sehingga dihasilkan 120 data. Analisis data tingkat kebisingan menggunakan SNI 7231 : 2009. Hasil pengukuran tingkat kebisingan menunjukkan bahwa media peredam tanaman pucuk merah dapat mereduksi kebisingan dengan intensitas awal 89,9 dB menjadi 84,45 dB (transmission loss 5,45 dB) sedangkan media peredam tanaman asoka mampu mereduksi tingkat kebisingan menjadi 84,9 dB (transmission loss 5 dB). Efisiensi penurunan tingkat kebisingan oleh tanaman pucuk merah sebesar 6,06% lebih baik dibandingkan efisiensi penurunan oleh tanaman asoka sebesar 5,88% karena kerapatan daun tanaman pucuk merah lebih besar (7.843 cm) lebih besar dari tingkat kerapatan daun asoka (4.803 cm).

El Objetivo describir el compromiso académico de los estudiantes de odontología de una institución privada en Cartagena que realizan práctica clínica. Métodos: estudio descriptivo de corte transversal, a partir de una población de 90 estudiantes se logró una muestra no probabilística de 79 estudiantes que cumplieron con los criterios de selección y otorgaron su consentimiento informado, considerando la normativa nacional vigente para Colombia resolución 008430 de 1993 y tras garantizar confidencialidad de sus datos. La información demográfica se recolectó en un cuestionario valorado mediante juicio de expertos, y se adicionó al final del formato el instrumento Utrecht Work Engagement Scale versión de 9 items (mediante una estructura de respuestas en escala tipo Likert) para valorar los factores vigor, dedicación y absorción. Para el análisis de datos, se empleó el software IBM SPSS Statistics Base V22. 0.0 y se aplicaron medidas descriptivas. Resultados: El análisis de fiabilidad arrojó un valor de 0,90 y para las respectivas dimensiones vigor 0,85, dedicación 0,87 y absorción 0,82. La edad promedio de los participantes fue 22,5 años, (DE= 2,5 años), predominó el sexo femenino. El semestre que otorgó el mayor número de participantes fue séptimo. En tan solo un tercio de los estudiantes se evidenció una respuesta de diariamente en lo referente a que les apetezca asistir a clase, estar feliz cuando se realizan tareas relacionadas con los estudios y dejarse llevar cuando realizan sus actividades. Conclusión: Los estudiantes valorados tienen compromiso académico, sin embrago algunos ítems de Utrecht generan cierta preocupación por las frecuencias bajas reportadas por los estudiantes durante la realización de su práctica, lo que implica en próximas investigaciones la búsqueda de las causas asociadas con estas respuestas que pueden llegar a afectar el compromiso académico.

La pandemia COVID 19 provocó el estancamiento en prácticamente en todos los sectores de la economía en todos los países del globo. Paradójicamente, en México unos cuantos sectores de la economía se han visto favorecidos y en lugar de estancarse y venirse abajo, han tenido crecimiento sin precedentes. A través de una investigación documental, en este trabajo se realiza un análisis de las condiciones del sector agropecuario mexicano en tiempos de la pandemia del COVID-19, a partir de la revisión histórica de las diferentes etapas del sector durante el siglo XX y lo que va el presente. Los resultados indican que, en las últimas décadas del periodo neoliberal, el campo mexicano pasó por una crisis que se volvió endémica. Posteriormente se investiga el comportamiento de productos representativos del sector agropecuario durante los últimos años y se demuestra su crecimiento inesperado durante la época pandémica. Se propone que los organismos que son cabeza del sector desarrollen e implanten políticas que permitan mejorar el comportamiento de la economía nacional aprovechando el impulso del momento de crisis.

As the Indian economy grows, the epidemic of Medo Rogahas spread across the country. The food we eat on a daily basis contributes to our health. However, many people's desire to eat more and exercise less is hastening the spread of the Medo Roga.Obesity is spreading in the modern day due to lifestyle changes and increased consumption of junk food combined with a stressful lifestyle. According to recent studies, high cholesterol is present in 25-30% of urban and 15-20% of rural subjects. This prevalence islower in low-income countries than in high-income countries. This negative health consequence could be the cause of a variety of lifestyle disorders such as dyslipidemia, hyperlipidemia, malnutrition, and osteoarthritis, among others. In today's fast-paced world, dyslipidemia is a major lifestyle disorder. The ramifications of Medo Vikritiand its dangers have been well documented in our classics. Medorogais primarily an Agni imbalance caused by a variety of etiological causes, including Aaharatmak, Viharatmak, Mansik,and others such as Bijabhava(hereditary). There is no such phrase as dyslipidemia in Ayurveda texts, however the qualities of Sneha Dravyaare defined as Medodhatu in Ayurveda.

Las infecciones intrahospitalarias son aquellas que se adquieren en el proceso de atención o estancia hospitalaria, son frecuentes y se asocian a ciertos parámetros en pacientes y en los procesos de intervención; estas pueden ser evitadas tomando medidas de prevención en los procedimientos de atención de pacientes. El objetivo general de este artículo fue analizar los factores de riesgo de infecciones intrahospitalarias y las medidas de prevención por parte del personal de enfermería. Para ello, se realizó una revisión bibliográfica de fuentes primarias y secundarias, lo cual se complementó con un estudio de tipo observacional donde se obtuvieron datos reales mediante la aplicación de la técnica de la encuesta a una población de 73 enfermeras del Hospital Doctor Rodríguez Zambrano (HRZ) de la Ciudad de Manta, para procesamiento de la información obtenida se empleó el método descriptivo y analítico. Entre los resultados del análisis estadístico de las encuestas, se logró cuantificar los factores de riesgos más relevantes que fueron del mayor al menor para pacientes: la estancia mayor de 7 días (25%), el uso de dispositivos sondas, tubos, entre otros (22%); y las comorbilidades (16%); para el personal de enfermería se destacó: el incumplimiento de las técnicas de asepsia (47%), manipulación de sangre y fluidos (19%) y el mal manejo de los desechos (15%). Como conclusión se pudo evidenciar insuficiente conocimiento sobre el tema en el personal de enfermería, así como el incumplimiento de las normas de bioseguridad.
