MODELO PSICOLÓGICO DE LA INTENCIONALIDAD Y SU CONTRASTACIÓN EMPÍRICA
Authors: TORRES CASTRO HILDA SOLEDAD , MIRANDA GALLARDO ALBERTO
Published: May 2024

Este trabajo se centra en el desarrollo del modelo psicológico de la intencionalidad, que ha evolucionado a través de dos etapas teóricas. La primera etapa se basa en la versión original del modelo (Miranda & Torres, 2015), mientras que la segunda etapa reformula y enfatiza aspectos clave, situando al modelo dentro de una perspectiva holística, integral y cognitiva de la intencionalidad, no es reduccionista.
Para fortalecer el modelo teórico, se realizó una contrastación empírica, que implicó la medición de constructos teóricos a través de seis escalas. Como confirman Nunally y Bernstein (1995), la medición de un fenómeno es esencial para cualquier actividad científica. En este sentido, se presentan las características psicométricas de cada escala.
El vínculo entre la teoría y la práctica conduce la contrastación teórica-empírica. Este proceso permite evaluar si las predicciones o postulados teóricos corresponden con los datos y fenómenos observables (Granato, Lo, & Sunny, 2010).
Se concluye que la intencionalidad de un individuo se explica tanto por el comportamiento consciente y propositivo como por el inconsciente o automático. Además, la intencionalidad está vinculada a la motivación hacia el logro de una meta, al aprendizaje y a la autorregulación. El lenguaje actúa como mediador y, por último, pero no menos importante, los procesos anticipatorios juegan un papel crucial.
Es importante mencionar que la validación de este modelo se realizó en una población específica, por lo que se recomienda ampliar su aplicación a diversas poblaciones para confirmar sus características psicométricas. Se sugiere continuar trabajando en este modelo para consolidarlo tanto en el plano teórico-conceptual como metodológico.

Published: May 2024

The purpose of this study is to explore the effect of service quality and perceived utility on customer loyalty in the digital money business, with particular emphasis on the intervening function of consumer satisfaction. The research method is quantitative, employing survey methodology. The sample for this study was made up of ewallet users who reside in DKI Jakarta and have made at least two online digital transactions with their e-wallet in the last six months. All variables were trustworthy, valid, and met the standards of the investigation. SPSS and Structural Equation Modeling were used to analyze the data (SEM). The data reveals that, first and foremost, service quality and perceived utility affect customer satisfaction positively. Second, customer satisfaction functions as a moderator between service quality, perceived utility, and client loyalty. Third, customer loyalty is linked to service quality and perceived value, but only in a small way. As a result of this finding, consumer satisfaction plays a critical role in fostering loyalty. The conclusion is that in the digital money business, superior quality and utility may impact clients positively but do not always result in loyalty. To accomplish this, digital currency players must place a premium on client pleasure. Keywords— Customer Satisfaction; Perceived Usefulness,Service; Quality; Customer Loyalty
دور الرصانة العلمية للبحوث الإسلامية في التعامل مع الأفكار الوافدة

يتناول البحث دور الرصانة العلمية في تعامل بحوث الإسلامية مع الأفكار الوافدة، وذلك لأنّ هناك قصورا من بعض الباحثين في التعامل مع مشاريع التغريب والأفكار الوافدة التي غزت مجتمعاتنا؛ ولذا كان لابدّ من تبنّي رصانة علمية متميزة في التعامل مع هذه الأفكار، من خلال الدعوة الى تبني الإبداع الفكري النابع من أصالة الأفكار الإسلامية، ويكون أيضاً بالنقد والمراجعة وعدم القبول بكل مكتسبات المعرفة الإنسانية التي جاء بها والاعتراض على كوّنية الأفكار الغربية بعد اخضاعها للفحص والتجربة والتجريح، وكذلك يتناول البحث بيان أثر التعددية الحضارية ودورها في التفاعل والتدافع والتسابق، والتي ترفض الصراع والسكون والموت فالعالم عبارة عن منتدى حضارات، وليس حضارة واحدة تفرض نفسها على باقي الحضارات بالتبعية والذوبان، كما يتناول البحث أيضاً بيان أثر الحوار الحضاري في التلاقح الحضاري والتفاعل الإنساني من أجل التعارف والتعايش السلمي، والدعوة بالتي هي أحسن، وهذه الدعوة يترتّب عليها التبادل والتوارث، والتفاعل الحضاري، وليس الصراع والقتال لإلغاء وسحق الشعوب والحضارات، وينطلق البحث أيضاً من رؤية بيان دور التكامل المعرفي في إنتاج رصانة علمية في مواجهة الأفكار المختلفة، ويرتبط هذا التكامل بالجمع بين القراءتين قراءة الوحي الكتاب المسطور، وقراءة الوجود الكتاب المنظور، ويتناول أيضاً الانفتاح على الأمم والحضارات والأفكار والمنتجات الإيجابية، والتي تعد ضرورة فكرية يمليها الواقع، وتقضيها الطبيعة البشرية، على أن لا يؤدي هذا الانفتاح إلى الذوبان والانصهار والتماهي مع الآخر.

تعد مشكلة جنوب السودان ذات اهمية كبيرة في التاريخ المعاصر إذ برزت كأهم القضايا التي تركت أثراً في تاريخه و وضعه العام  على مختلف الانظمة السياسية التي تعاقبت على حكم البلاد والذي انعكس بدوره على الشعب السوداني ,كما اتخذت الكثير من المواقف الإقليمية والدولية إزاء المشكلة (التي حدثت بين الجنوب والشمال السوداني ) وكانت المواقف حسب ما تقتضيه مصلحة كل دولة اتجاه السودان ,فضلاٍ عن تدخل العديد من الدول بمشكلة السودان لاسيما بافتعالها أو بعد حدوثها وقد كانت لتلك التدخلات الأثر الكبير باستمرار وتصاعد المشكلة والتأخير في وجود حلول لها ,ومن هنا جاء سبب اختيار عنوان الدراسة ( موقف العراق من مشكلة جنوب السودان 1956-2011 ) , لتوضح ما هو موقف العراق من المشكلة وهل أستمر ذلك من بدايتها حتى نهايتها (1956 – 2011 ) ,ولذا قُسمت الدراسة الى مقدمة وثلاثة محاور وخاتمة .
     جاء المحور الأول بعنوان (مشكلة جنوب السودان) حيث وضح فيه جذور المشكلة واطرافها وكيف ومتى بدأت ,وتطرق كذلك للقوى الاوربية الاستعمارية التي كان لها اليد الطولى في حدوث مشكلة جنوب السودان  , وبعدها عرج على الحروب الاهلية الأولى (1955 – 1972 ) والثانية ( 1983 – 2005 ) وبين كل منهما واسبابهما ونتائجهما .
     في حين حمل المحور الثاني عنوان (العلاقات العراقية – السودانية ) تطرق فيه لموقف العراق من استقلال السودان 1956 ,وتحدث ايضاً عن التعاون بينهم وكذلك العلاقات العراقية – السودانية خلال الانقلابات التي حدثت في السودان ومنها (انقلاب جعفر النميري 1969 ,وانقلاب هاشم عطا 1971) وموقف العراق منها .
    تناول المحور الثالث والاخير (الحلول والتسويات) إذ تناول فيه اتفاقيات التسوية لحل المشكلة ومنها اتفاقية اديس ابابا 1971 واتفاقية نيفاشا (اتفاقية السلام العام )2005 التي كان أهم نتائجها انفصال جنوب السودان عن شماله  .
    بينا بعد ذلك أهم النتائج التي توصلنا اليها حول الدراسة إذ كان للعراق علاقات تعاونية اخوية مع السودان وكان مسانداً له ,كما كان لهُ موقف إزاء مشكلة جنوب السودان وانفصاله ,إذ لم يكن هناك موقف للجمهورية العراقية ألا في الأعوام الأولى للمشكلة ,لأنه فيما بعد تعرض للكثير من الأحداث التي جعلته غير قادر على إبداء رأي أو اعطاء موقف بالنسبة للقضايا الدولية ومنها مشكلة جنوب السودان وانفصاله عن الشمال ومن هذه الاحداث الحرب العراقية الايرانية وبعدها الحرب العراقية الكويتية ثم تدهور اوضاع العراق السياسية والامنية والاقتصادية في نهايات العقد الأخير من القرن العشرين ,وبعد ذلك تعرضه للاحتلال الامريكي عام 2003 وتدهور اوضاع العراق كافة , فضلاٍ عن تعرضه للأعمال الارهابية التعسفية التي شغلت الرأي العراقي العام على صعيد الحكومة والشعب ,ولذلك لم يبدر من العراق أي موقف بعد 2003 حتى حين تم انفصال جنوب السودان عن شماله عام 2011 .

Real-Time Hybrid Coiled Tubing Intervention Used to Complete the Longest Ever-Recorded Cement Millout Operation: 4,000 Meters of Cement Successfully Milled in Oman While Reducing Waste to Optimize Intervention Costs & Time By 70%
Authors: Khalil Mohamed Amin , Gaur Rishika , Jahwari Khalifa Al
Published: May 2024

An unsuccessful cement job left a well in the Sultanate of Oman with 4,000 meters of undesired cement plug, putting customer investment at risk. The cement obstruction required an extended intervention operation to complete the well for a planned hydraulic fracturing treatment. Concerns were raised about the potential operation duration and the number of motors and mills to be deployed. Preliminary estimates indicated that 90 days would be required to reach TD.

Real-Time Hybrid Coiled Tubing (RTHCT) with an unlimited power supply was proposed to provide downhole insight through real-time weight on bit and torque readings to optimize the motor performance and minimize the number of runs and motors. Planning for such an operation was crucial, including having all Bottom Hole Assembly (BHA) components available to cover all planned runs and expected contingencies such as stuck pipe. The first run was planned with a junk mill to help mill the top plug and cement, followed by a bear claw mill to help improve the penetration rate, and then a standard polycrystalline diamond compact bit for cement milling. A variety of different size taper mills were also made available to clear any required restrictions.

The cement milling operation was successfully completed in four (4) runs, averaging four (4) days per run. The RTHCT helped drive the decision-making process on location by pulling out of hole only when motor torque was insufficient. 1,460 m and 1,550 m were achieved on the first and second runs utilizing the three planned mills. The downhole sensors in the BHA provided real-time insight to optimize the motor performance, evaluate the motor life, and maximize results on every run. The job was completed without a single motor stall and approximately seven (7) times higher overall Rate of Penetration (ROP) than conventional CT milling operations. After successful milling, a high-pressure rotating jet nozzle was run to help ensure no cement sheath remained that could jeopardize future interventions. Research indicates that 4,000 m of cement milling is greater than any other CT operation has achieved globally in a single well.

The RTHCT combined intervention and diagnostic capabilities to provide real-time downhole insight for a precise decision-making process to achieve the operation's success. The operator saved a high investment well along with the rig costs that would normally be associated with such an operation.

This paper discusses the collaborative efforts from planning and design to executing this successful operation, including the contingency plans that were crucial in reducing the time to plan resources during unexpected events.

Published: May 2024

Objectives:

The effect of homoeopathic potentization increases with dilution. The physical and chemical properties of the homoeopathy solution change as a function of the concentration of nanoparticles (NPs). The succussion process is also vital in homoeopathy. However, none of these factors, along with the container of the medicine, have been well-researched to date.

Material and Methods:

We studied the systematic ultra-low dilution (up to 10200 times) effect of homoeopathic remedy of Aurum Metallicum (Gold) NP colloidal solution to determine the mechanism of colloidal formation in such extreme dilution. Several material characterizations were also performed to consolidate our results.

Results:

Optical spectroscopy confirmed the presence of NPs with narrow size distribution and high surface activity in higher dilution (up to 10200 times) homoeopathic solution. The particle size analysis of the serially diluted solution showed that the size distribution becomes narrow with increasing dilution. Transmission electron microscopy confirmed the presence of NPs in solutions up to 10200 times dilution.

Conclusion:

The process of dilution introduces an active hydrocarbon layer on these NPs. The experimental study further confirmed theoretical calculations. The understanding of such extreme dilutions can be utilized in biomedical applications, especially in homoeopathic medicine.
Authorship issues in a research article
Authors: Ambwani Meenakshi , Nayak Chaturbhuja
Published: May 2024

The authorship issue is a very sensitive area in scientific publications. Fulfilling the authorship criteria of the International Committee of Medical Journal Editors is the basis of inclusion as an author in an article. Courtesy authorships have always been regarded as a means of misconduct in the publication world and lead to conflict among authors. This practice often denies an individual the credit that he deserves to be an author for the originality and creativity of his work. There is a need to curb the practice of inappropriate and unethical authorship. A few guidelines and an authorship index have been proposed that determine the author’s contribution to scientific writing. Authorship issues from the legal point of view have also been discussed in the article. Awareness programmes and seminars must be conducted to make researchers aware of the need to decide the authorship issues appropriately.

Authors: Muzychuk R.I. , Saneev B.G. , Sokolov A.D.
Published: May 2024

The Asian regions of Russia play a significant role in the energy sector of the country. Almost 96% of coal and 25% of electricity produced in the country is produced in Asian Russia. More than 50% of this electricity is produced by hydro power plants. The reporting fuel and energy balances (FEBs) are the basis for strategic planning of the energy development of these regions. Specialists of the Melentiev Energy Systems Institute of Siberian Branch of the Russian Academy of Sciences (ESI SB RAS) built the reporting FEBs of the Asian regions for 2020 using the information and reference system for the development of regional FEBs. The FEB made for the Asian regions of Russia give the opportunity to determine the structures of production and consumption of fuel and energy resources in the territory and evaluate the efficiency of their use. The analysis of the FEBs shows the need to improve the energy balance of the Asian regions in terms of changing its structure and increasing energy efficiency and environmental friendliness of fuel use.

PCET-driven Reactivity of Neptunyl(VI) Yields Oxo-bridged Np(V) and Np(IV) Species
Authors: Mikeska Emily , Wilson Richard , Blakemore James
Published: May 2024

A reaction sequence based upon the principles of proton-coupled electron transfer (PCET) has been used to access two unconventional oxo-deficient polynuclear complexes of neptunium (Np). The complexes featuring mono-μ2-oxo motifs assemble under ambient atmosphere upon dissolution of neptunyl(VI) diacetate dihydrate (NpO2(OAc)2(H2O)2·HOAc) in methanol followed by addition of a supporting pentadentate ligand (LNM); one complex is a mixed-valent [NpV,NpIV,NpV ] trimer with two bridging μ2-oxos and the other is a [NpV,NpV ] dimer featuring a single μ2-oxo. The outer Np centers are also capped with terminal oxo ligands. Spectroscopic and spectrokinetic findings show that intermediate [NpV O2(OAc)]n species form prior to metal chelation by LNM; electrolysis experiments demonstrate that production of Np(V) gives rise to asynchronous proton transfer that does not occur otherwise (in the Np(VI) state) as well as condensation (loss of H2O) and formation of the polynuclear complexes. The oxo-deficient nature of these products is attributable to the reduction/condensation reaction sequence of PCET. Consequently, PCET reactivity appears poised to complement more established techniques for interconverting actinide oxidation states, a prospect with considerable applications in fuel recycling for low-carbon nuclear energy.
The Role of Double Excitations in Exciton Dynamics of Multiazobenzenes: Trisazobenzenophane as a Test Case
Authors: Titov Evgenii
Published: May 2024

Molecular exciton dynamics underlie energy and charge transfer processes in organic multichromophoric systems. A particularly interesting class of the latter are multiphotochromic systems made of molecules capable of photochemical transformations. Exciton dynamics in assemblies of photoswitches have been recently investigated using either molecular exciton model or supermolecular configuration interaction (CI) singles, both approaches being based on a semiempirical Hamiltonian and combined with surface hopping molecular dynamics. Here, we study how inclusion of double excitations in nonadiabatic dynamics simulations affect exciton dynamics of multiazobenzenes, using trisazobenzenophane as an example. We find that both CI singles and CI singles and doubles yield virtually the same timescale of dynamical exciton localization, ∼50 fs for the studied multiazobenzene. However, inclusion of double excitations considerably affects excited state lifetimes and isomerization quantum yields.
Electronic Structure of a Neodymium(III) tris(oxydiacetate) Complex from Luminescence data and ab initio Calculations
Authors: Nielsen Villads R. M. , Grasser Maxime , Mortensen Sabina Svava , Le Guennic Boris , Sørensen Thomas Just
Published: May 2024

Neodymium(III) is a NIR emissive and magnetic ion, which has found use in various high-technology applications. Yet, accurate predictions of the luminescent and magnetic properties of neodymium(III) based on the coordination environment remain to be done. Guideline exists, but to build structure-property relationships for this element, more data are needed. Herein, we present a high-symmetry starting point. The tris(oxydiacetate) complex of neodymium(III) was prepared and crystallised, and access to the experimentally determined structure allows us to quantify the symmetry of the compound and to perform calculations directly on the same structure that is investigated experimentally. The luminescent properties were determined and the electronic structure was computed using state-of-the-art ab initio methods. All electronic transitions in the range from 490 to 1400 nm were mapped experimentally. Using a Boltzmann population analysis, the combination of the excitation and emission spectra revealed the crystal field splitting of the 18 lowest energy Kramers levels that experimentally could be unambiguously resolved. This assignment was supported by ab initio calculations and the crystal field splitting was well reproduced. The electronic structure reported for the tris(oxydiacetate) complex is used to deduce the coordination structure in aqueous solution. Finally, the results are compared to empirical trends in the literature for the electronic structure of neodymium(III).
Isolation and Crystallographic Characterization of an Octavalent Co2O2 Diamond Core
Authors: Schneider Joseph , Zeng Shilin , Anferov Sophie , Filatov Alexander , Anderson John
Published: May 2024

High-valent cobalt-oxides play a pivotal role in alternative energy technology as catalysts for water splitting and as cath-odes in lithium-ion batteries. Despite this importance, the properties governing the stability of high-valent cobalt-oxides, and specifically possible oxygen evolution pathways, are not clear. One root of this limited understanding is the scarcity of high-valent, Co(IV)-containing model complexes; there are no reports of stable, well-defined complexes with multiple Co(IV) centers. Here, an oxidatively robust fluorinated ligand scaffold enables the isolation and crystallographic charac-terization of a Co(IV)2-bis-μ-oxo complex. This complex is remarkably stable, in stark contrast with previously reported Co(IV)2 species which are highly reactive, which demonstrates that oxy-Co(IV)2 species are not necessarily unstable with respect to oxygen evolution. This example underscores a new design strategy for highly oxidizing transition metal frag-ments and provides detailed data on a previously inaccessible chemical unit of relevance to O–O bond formation and oxygen evolution.
Dysbiosis of the intestinal microbiota and type 2 diabetes mellitus, modern correction strategies: A review
Authors: Isaeva Regina A. , Alimetova Zulfiya R. , Isaeva Guzel  Sh.
Published: May 2024

Diabetes mellitus has now assumed an epidemic character and acquired the characteristics of a pandemic disease. In recent decades, special attention has been paid to the importance of the intestinal microbiome in the pathogenesis of diabetes. The purpose of the review was to study the correlation between the intestinal microbiota and type 2 diabetes mellitus (DM 2), to assess the prospects for the prevention and treatment of DM 2 by correcting dysbiotic disorders. Studies of the intestinal microbiota have shown a correlation between plasma glucose levels and changes in the composition of the microbiota, namely with a decrease in representatives of the Firmicutes type and an increase in Proteobacteria, a change in the ratio of Bacteroidetes to Firmicutes. In patients with DM 2, the population of butyrate-producing bacteria decreases against the background of the growth of opportunistic opportunists, mucin-decomposing bacteria and sulfite-reducing bacteria. The presence of a link between the composition of intestinal microbiota and DM 2 was confirmed during experimental studies on animal models and on groups of volunteers. New approaches to studying the risk of developing DM 2 and dysbiotic disorders may be associated with the use of artificial intelligence. A promising direction for the use of probiotic microorganisms for the correction of metabolic disorders of DM 2 is the use of both classical probiotics – representatives of the genera Lactobacillus and Bifidobacterium, as well as new probiotics from the intestinal normobiota Akkermansia muciniphila, Faecalibacterium prausnitzii and genetically modified microorganisms Lactococcus lactis (LL-pUBGLP-1). One of the new techniques for correcting dysbiotic disorders in DM 2 is fecal microbiota transplantation. The intestinal microbiota can be used not only as a diagnostic biomarker of DM 2, but also as a potential target for the development of new therapeutic approaches. The use of prebiotics, probiotics, postbiotics and pharmacobiotics, which can have a therapeutic effect by influencing the pathogenetic mechanisms in DM 2, requires further multicenter studies using multiomic technologies.
Sodium-glucose cotransporter 2 inhibitors: mechanisms of cardiorenal protection: A review
Authors: Leonova Marina V.
Published: May 2024

Sodium-glucose cotransporter 2 inhibitors (SGLT-2) are a new class of hypoglycemic drugs that were initially approved for the treatment of type 2 diabetes. Currently, 5 drugs in the SGLT-2 class of drugs are approved by the FDA for glycemic control: canagliflozin, dapagliflozin, empagliflozin, ertugliflozin and sotagliflozin. However, their effectiveness in reducing the risk of heart failure and progression of chronic kidney disease was soon established, regardless of diabetes status. In addition, according to a number of meta-analyses of RCTs in patients with cardiometabolic and renal diseases, the use of SGLT-2 reduces cardiovascular and overall mortality and the number of serious adverse cardiac events and renal outcomes in patients with or without diabetes, which is reflected in the indications to their use. Scientific data are presented in a discussion of the mechanisms of cardioprotective and renoprotective effects of the SGLT-2 class, many of which are considered as pleiotropic effects not related to the effect on glycemic levels.

Published: May 2024

The purpose of this study is to find out how the perceptions of parents of SD Tri Tunggal students that fat children are funny and healthy can be formed. Type of this research is qualitative with phenomenology approach. Data were collected by in-depth interview and observation. Research subjects as many as 8 people consisting of 5 parents of Primary School Tri Tunggal, 1 child pediatrician, 1 nutritionist, 1 sports expert. Data were analyzed by content analysis. The results showed that the perception of parents who consider the fat child is funny and healthy is formed because through the first process they like to see and feel the pleasant sensation to see and hug the fat child, plus they have a feeling of proud to have fat children because they consider successfully taking care of their children. After going through the first process, parents lack the hope, motivation and a firm attitude to reduce child obesity. Parents assume if the fat little boy is still funny and healthy. The next process parents have had some bad experience about childhood obesity but looks not considered a serious experience to be addressed, resulting in a learning process that is very less for parents. In the end, parents have the wrong perception of childhood obesity.

KENDALI PID PADA QUADCOPTER UNTUK GERAK ATTITUDE PITCH DAN ROLL SAAT HOVERING
Authors: Nugroho Agung , Khairurozi Haris , Suprijono Herwin , Heryanto M Ary
Published: May 2024

The quadcopter represents one of the emerging research areas in unmanned aerial vehicle (UAV) technology. One of its advantages lies in its simple mechanism and smaller propeller size compared to helicopters, while maintaining the same lifting capacity. The quadcopter employs inner and outer control schemes, where the inner control manages attitude roll, pitch, yaw, and altitude, thereby affecting the motion of the quadcopter. Meanwhile, the outer control governs the direction of the quadcopter's movement. This condition underscores the significance of inner control, ensuring the quadcopter's maneuverability. Consequently, there is a need to design an attitude, pitch, and roll control using the PID method. This experiment focuses on roll and pitch control under hover conditions. The PID control experiment yielded optimal results with parameters KP = 60, KI = 22, and KD = 14, exhibiting rapid response, absence of oscillation, deviations smaller than 20o in both roll and pitch controls, and the ability to return the attitude to the initial setpoint position when disturbances occur.

ABSTRAK

Quadcopter merupakan salah satu bidang riset yang baru dalam teknologi unmanned aerial vehicle (UAV). Salah satu keunggulan pada Quadcopter adalah mekanisme yang sederhana dan ukuran pada baling-baling yang lebih kecil dibandingkan dengan helicopter dengan daya angkat yang sama. Quadcopter memiliki skema kendali inner dan kendali outer, dimana kendali inner mengendalikan attitude roll, pitch, yaw, dan altitude yang berimplikasi pada gerak quadcopter. Sedangkan kendali outer mengendalikan arah gerak quadcopter. Kondisi ini menjadikan kendali inner sangat penting sehingga mampu menjaga quadcopter dapat bergerak. Untuk itu perlu dirancang suatu kendali attitude pitch dan roll dengan metode PID. Eksperimen ini focus pada kendali roll dan pitch di kondisi hover. Hasil eksperimen kendali PID pada roll dan pitch didapatkan hasil terbaik pada parameter KP=60, KI=22, dan KD=14 yang memiliki respon cepat, tidak terjadi osilasi, lonjakan lebih kecil dari 20o baik pada kendali roll maupun pitch, dan mampu mengembalikan attitude pada posisi setpoint awal apabila diberi gangguan.

 
АНАЛІЗ ЕФЕКТИВНОСТІ АЛГОРИТМІВ РОЗВ’ЯЗАННЯ ЗАДАЧІ В’ЯЗКОПРУЖНОСТІ
Authors: Столярова А. В. , Барау К.
Published: May 2024

Розширення можливостей різноманітних девайсів для виконання різних задач проєктування елементів конструкцій вимагає покращення ефективності роботи залучених у розрахунках обчислювальних алгоритмів. У роботі описано два варіанти алгоритмів розв’язання задачі в’язкопружності для визначення напружено-деформованого стану конструкцій. Для описання в’язкопружної поведінки матеріалу конструкції використовуються інтегральні рівняння спадкової теорії Больцмана-Вольтера із ядрами різницевого типу. Для їх розв’язання використовується метод скінченних елементів у поєднанні з ітераційною процедурою за часовою змінною. Алгоритм ітераційної процедури передбачає дискретизацію відрізку часу із подальшим розв’язанням лінеарізованої задачі на кожному проміжку часу. Одним із варіантів дискретизації за часом є застосування рівномірного кроку. Іншим варіантом, що враховує особливості кривої деформування матеріалу, є обчислення кроку залежно від величини ядра релаксації віднесеного до кожного проміжку часу. Такий підхід дозволяє згустити сітку дискретних значень за часом у діапазоні, де кривизна кривої деформування більша, і зробити її розрідженою в діапазоні, де крива близька до прямої лінії. На основі обох варіантів алгоритму створено пакет прикладних програм для розв’язання просторових задач в’язкопружності. За допомогою програмного пакету проведено низку обчислювальних експериментів для розрахунку в’язкопружної задачі для гумового порожнистого циліндру під дією внутрішнього тиску із затисненою зовнішною циліндричною поверхнею. Як різницеве ядро використано ядро Ю.М. Работнова. Чисельні розв’язки показують, що алгоритм розв’язання задачі в’язкопружності із другим варіантом вибору кроку дає більш адекватні результати, ніж при рівномірному розбитті. Машинний час розрахунків у обох випадках різниться несуттєво.
Comparing the Pre-COVID-19 Pandemic and During-Pandemic Hospitalizations of Youth Ages 5-24 for Mental Health Disorders in Canada

Published: May 2024

Introduction: The COVID-19 pandemic exacerbated mental health issues in children due to the anxiety and fear it propagated worldwide. This study aims to compare the instances of youth hospitalizations for mental health disorders across Canada before and during the COVID-19 pandemic. This paper also compares the differences in rates of youth hospitalizations due to mental health disorders per 100,000 in Western, Eastern, and Northern regions of Canada. Thus, the impact of discrepancies in COVID-19 pandemic restrictions on the prevalence of mental health disorders in youth in different regions of Canada is examined. Methods: The data used in this study was obtained from the Canadian Institute for Health Information (CIHI) database. Data was sorted into the pre-pandemic or during-pandemic period and into Eastern, Western, and Northern provinces and territories. A Wilcoxon Signed Rank Test was conducted to compare the differences in hospitalization rates. A Kruskal-Wallis Test was conducted to compare the differences in pre-pandemic and during-pandemic rates between the geographic regions. Results: Overall, results indicate that the pandemic significantly decreased the prevalence of hospitalizations for mental health disorders in youth in Canada. The results of Wilcoxon Signed Rank Test were statistically significant (p<0.001). The results of the Kruskal-Wallis Test were not statistically significant (p=0.2682). Discussion: Across all regions of Canada, there was a statistically significant decrease in hospitalizations during the pandemic. One possible reason for this decrease is that fear of attending hospitals was exacerbated by the COVID-19 pandemic. Limitations include: data on rates of hospitalizations of youth do not take into account more than 1 hospitalization per child, non-hospitalized cases were not considered, fear of seeking help, lack of extensive coverage, as well as the ongoing nature of the pandemic. The only demographic or social factor covered in this paper is geographic location. Conclusion: Further research is needed to better understand the specific factors contributing to the decrease in hospitalizations for mental health disorders among youth in Canada during the pandemic and to identify effective interventions that can address these issues.

Published: May 2024

The implementation of waste management from upstream (community) by the Yogyakarta City Government has had an impact on the city community, including residents of RW 6 Demangan Sub-district, Gondokusuman District. Communities have limited knowledge and ability to manage inorganic waste independently. Facing these problems, the community needs assistance to increase knowledge and develop the ability to manage inorganic waste. This is important so that the Yogyakarta City Government's goal of achieving zero inorganic waste can be realized. The community service program aims to educate the community through training and workshop in waste management and processing so that it can reduce the production of inorganic waste. Assistance in the form of education, training, and practices in managing and processing inorganic waste needs to be carried out to increase the knowledge and skills of the community so that waste self-management can be realized. The community service results show that the community of RW 06 is able to manage and process waste. However, waste management and processing activities must be carried out consistently so that the target of zero inorganic waste is achieved.
