Authors: Munir Rashid , Wahab Abdul , Perveen Maqsooda , Khan Aamna , Kashif Abdul Rauf , Shehzad Muhammad Ahmed
Published: April 2023

The purpose of this study was to find out the impact of job resources on employees turnover intention. It also aimed at examining the moderating role of job demand (time pressure) in the relationship of job resources and employee engagement. Data was collected from the employees of universities, including administrative employees and all academic employees (lecturer to professors). The findings exhibit that reward & recognition affect turnover intention positively and significantly. It was also found by regression analysis that organizational support has a positive impact on employee engagement. Moreover, this study also found that time pressure has a moderating role in the relationship of reward & recognition and employee engagement. Similarly, it was the findings of this study that negative moderation effect exists between the relationship of organizational support and employee engagement. Therefore, it is arguable that time pressure or extra job demand decreases the employee engagement.

Authors: Kozlovskii V. E. , Kolmogorova S. S. , Kolmogorov S. G.
Published: April 2023

Choosing the optimum tool shape for soil cutting is an urgent task for shaftsinking and tunnelling as well as in soil treatment for agriculture. The roadhead shape at the available load determines the stress-strain state of soil and development depth in the bottomhole area. By changing the roadhead contour, the penetration efficiency can be increased, while the feed force and tool wear can be reduced.Purpose: The aim of the work is to create the roadhead calculation algorithm and determine the stress-strain state of soil near it with a minimum number of boundary conditions, no discretization of the entire region into elements and approximation between nodes.Design/methodology: Test tasks for the proposed methodology for the roadhead and the bottom-hole area. The numerical model of the boundary conditions is based on the integral formulation of the Kelvin elasticity theory problem and uses the potential method as fictitious loads and discontinuous displacements, that makes it possible to minimize the problem with regard to symmetry, obtain a more compact system of equations and give accurate solutions at any domain point.Research findings: The assessment of the stress state of the roadhead of various shape and the bottom-hole zone of soil; loss of soil strength calculated according to the Mohr–Coulomb theory.Originality/value: The proposed method for solving the boundary value problem is recommended as an express method for estimating the roadhead stress state of an arbitrary shape in infinite regions with regard to the symmetry and implementation in Excel.

МЕТОД ЗЛИТТЯ БАГАТОМОДАЛЬНИХ ВЕКТОРНИХ ПРЕДСТАВЛЕНЬ СЛІВ У МАЛОРЕСУРСНОМУ СЕРЕДОВИЩІ
Authors: ШАПТАЛА Роман , КИСЕЛЬОВ Геннадій
Published: April 2023

У даній статті представлено метод злиття багатомодальних векторних представлень слів у малоресурсному середовищі. Цей метод, на відміну від інших методів злиття векторних представлень слів, враховує обмеження малоресурсного середовища і дозволяє поєднувати вектори слів з різних джерел, таких як документи та словники. Метод покладається на обчислення міжрядкової відстані замість побудови повних синтаксичних і морфологічних моделей, що часто неможливо в малоресурсних мовах. Його можна використовувати на проміжних етапах побудови систем обробки природної мови та машинного навчання при вирішенні практичних завдань, таких як машинний переклад чи класифікація документів.

Крім того, проведено аналіз різних методів злиття багатомодальних векторних представлень слів у малоресурсному середовищі. У статті описуються переваги, недоліки та обмеження кожного підходу, враховуючи завдання побудови уніфікованого векторного представлення тексту в поєднанні з даними з додаткових джерел. У дослідженні прикладом завдання у малоресурсному середовищі була обрана класифікація петицій до Київської міської ради, написаних українською мовою.

Велика кількість функцій обчислення міжрядкової відстані ускладнює їх вибір при вирішенні практичних задач. Ми пропонуємо набір рекомендацій у контексті малоресурсних середовищ, а також методологію вибору найкращого для вирішення поставлених завдань. Проаналізовані функції обчислення міжрядкової відстані включають відстань Левенштейна, подібність Жаккара, Мангеттенську відстань, відстань Хеммінга та коефіцієнт Дайса. Наші результати демонструють, що метод на основі відстані Левенштейна збільшує якість класифікації документів сильніше, ніж альтернативи. Ці висновки мають практичне значення для різних сфер, включаючи обробку природної мови, аналіз текстів та пошук інформації.

Authors: Jia Zhuolin , Feng Yanyan , Wang Huanliang , Liang Lishuang
Published: April 2023

Tracheal perforation is a rare complication in thyroidectomy and intubation. The anesthesiologist needs more experience to make a timely diagnosis of tracheal perforation. However, there is little literature that discuss the intraoperative tracheal perforation. This article describes an unexpected tracheal perforation during thyroidectomy and reviews literature about risk factors, symptoms, and tracheal management. Case presentation — A 66-years-old female patient who was diagnosed with recurrent multinodular goiter, was planned to undergo subtotal thyroidectomy. When surgeon sutured the remain organ of thyroid, the anesthesiologist heard the air leakage near the trachea while the ventilator not showing insufficient ventilation. To find the damage position, appropriate saline that could cover the tracheal was injected into the surgical wound. Inflated the endotracheal tube cuff and some small bubbles emerged from a suture. The suspect that the damage was caused by over deep suture was confirmed, which tightly bonded the wall of the trachea with the cuff. Conclusions — In a word, for the surgery near-tracheal, the purpose of this case report was to recommend observe patient's condition more carefully, instead of simply relying on ventilator monitoring. In addition, if resistance is encountered during the extubation, the tube should not be blindly violently extubated.

Ramai antara mereka yang gagal mengikuti pengajian di universiti kerana gagal dalam kursus yang diikuti atau berhenti dari pusat pengajian kerana tidak dapat menyesuaikan diri dengan sistem pendidikan di peringkat tertiari yang amat berbeza dengan sistem pendidikan di sekolah menengah. Senario ini amat ketara bagi pelajar-pelajar tahun satu kerana tidak dapat menyesuaikan diri dengan kehidupan kampus. Pelajar dilihat tidak dapat menyesuaikan diri dengan persekitaran pembelajaran yang baru. Kajian ini adalah kajian rintis untuk melihat profil adaptasi pelajar baharu dalam kalangan pelajar di kolej komuniti. Kajian ini menggunakan kaedah tinjauan dan melibatkan seramai 70 orang pelajar tahun pertama yang memberi maklum balas terhadap 68 item soal selidik penyesuaian pelajar baharu Student Adaptation to College Questionnaire (SACQ) (Baker & Siryk,1999). Pembolehubah penyesuaian pelajar baharu terdiri daripada empat dimensi iaitu tahap penyesuaian akademik, penyesuaian sosial, penyesuaian peribadi-emosi dan komitmen matlamat/perapatan institusi. Analisis data bagi kajian ini adalah analisis deskriptif dengan menggunakan perisisan SPSS versi 21. Dapatan kajian menunjukkan tahap penyesuaian pelajar dalam kalangan pelajar tahun pertama kolej komuniti adalah pada tahap sederhana. Hasil analisis ujian-t menunjukkkan tidak terdapat perbezaan yang signifikan pada tahap penyesuaian pelajar antara jantina. Diharapkan dapatan kajian ini dapat membantu golongan pelajar, pihak pengurusan organisasi dan pihak yang terlibat secara langsung dengan hal ehwal pelajar bagi merancang program yang sesuai dengan pelajar baharu bagi menangani masalah ini.

Elimination of CM Noise from SMPS Circuit using EMI Filter
Authors: Sai Charishma Pathala Venkata , Y. Jayasree Pappu V.
Published: April 2023

The electronic devices are exposed to external electromagnetic signals that produce an unwanted signal called noise in the circuit, which causes electromagnetic interference [EMI] problems. It occurs in two modes: radiated mode and conducted mode. In the radiation mode, the shielding technique is used for radiation mode, in conduction mode filtering technique is used. The design of an EMI filter depends upon the type of noise generated by the Switched Mode Power supply circuit [SMPS]. The SMPS circuit used in this paper is a DC-DC power converter, the Boost converter is a step-up converter and Buck converter is step down converter are considered as equipment for generation of noise, the Line Impedance Stabilization Network [LISN]is used for generating the common output impedance to the power converters, the EMI filters are designed to eliminate noise generated by the circuits. There noise generated by this power converters is Common Mode [CM] noise and Differential Mode [DM] noise. The separation of noise from the equipment is done by using a noise separator. In this paper, CM noise generated by these power converters is eliminated by designing an EMI filter called an inductor filter and a PI filter. The comparison between the LC inductor filter and the PI filter for the boost and buck converters is observed. The PI filter has better performance characteristics when compared to the inductor filter for both SMPS circuits as per the Comité International Special des Perturbations Radioélectriques [CISPR] standards. This standard gives the conducted emission range for different electronic devices.

Authors: Beevi A Shamla , S. Ratheesha , Kalady Saidalavi , James Chakola Jenu
Published: April 2023

In computer vision, the extraction of robust features from images to construct models that automate image recognition and classification tasks is a prominent field of research. Handcrafted feature extraction and representation techniques become critical when dealing with limited hardware resource settings, low-quality images, and larger datasets. We propose two state-of-the-art handcrafted feature extraction techniques, Oriented FAST and Rotated BRIEF (ORB) and Accelerated KAZE (AKAZE), in combination with Bag of Visual Word (BOVW), to classify standard echocardiogram views using Machine learning (ML) algorithms. These novel approaches, ORB and AKAZE, which are rotation, scale, illumination, and noise invariant methods, outperform traditional methods. The despeckling algorithm Speckle Reduction Anisotropic Diffusion (SRAD), which is based on the Partial Differential Equation (PDE), was applied to echocardiogram images before feature extraction. Support Vector Machine (SVM), decision tree, and random forest algorithms correctly classified the feature vectors obtained from the ORB with accuracy rates of 96.5%, 76%, and 97.7%, respectively. Additionally, AKAZE's SVM, decision tree, and random forest algorithms outperformed state-of-the-art techniques with accuracy rates of 97.7%, 90%, and 99%, respectively.

Published: April 2023

This study aims to examine the impact of trust in the leader (TIL) as a mediating variable between the moral integrity (MI) of the leader and job engagement (JE) and to identify the consequent results that benefit officials in the surveyed institutions. The study population consisted of the employees of two public institutions (The Financial Supervisory Authority in the Governorate of Dhofar and the Directorate of Municipal Affairs in the Governorate of Dhofar). Primary data was collected from a convenient sample of 145 via an electronic questionnaire due to the directives related to social distancing in light of the global health crisis (COVID 19). The data were analysed using the Statistical Package for Social Sciences (SPSS) and Smart Partial Least Squares (Smart PLS). The findings of the study reveal that there is a statistically significant impact of the MI of the leader on the levels of JE on one hand and MI of the leader on the TIL, on the other hand. Moreover, it was also found that TIL partially mediates the relationships between the MI of the leader and JE.

The problems of traditional concrete such as brittleness, poor toughness and short service life of concrete engineering under acid rain or marine environment need to be solved urgently. Hydrated calcium silicate (C-S-H) is a key component to improve the mechanical properties and durability of concrete. However, the traditional method of concrete material design based on empirical models or comparative tests has become a bottleneck restricting the sustainable development of concrete. The synthesis method, molecular structure and properties of C-S-H were systematically described in this paper; The interface structure and interaction of graphene oxide / calcium silicate hydrate (C-S-H / GO) were discussed. On this basis, the saturated and unsaturated transport characteristics of ions and water molecules in C-S-H / GO nanochannels under the environment of ocean and acid rain were introduced. The contents of this review provide the basis for improving the multi-scale transmission theory and microstructure design of concrete. It has important guiding significance for analyzing and improving the service life of concrete in complex environment.

Meskipun sudah ada pembatasan umur menikah menurut UU No. 16 tahun 2019 pasal 7 ayat 1 yang berbunyi: Perkawinan hanya diizinkan apabila pria dan wanita sudah mencapai umur 19 (sembilan belas) tahun, namun pernikahan dini masih merupakan masalah di Indonesia. Pernikahan dini membawa dampak yang cukup banyak bukan hanya pada pasangan nikah tersebut, tapi juga kepada keturunan dan keluarga mereka. Tingkat perceraian cukup tinggi dan tingkat kesehatan serta ekonomi keluarga juga berpengaruh. Berdasarkan hal itu, dalam kegiatan Pengabdian kepada Masyarakat FK UKI di bulan Juni 2022, telah dilakukan pendataan terkait riwayat pernikahan dini warga Kelurahan Pulau Tidung-Kepulauan Seribu, Jakarta. Terdapat 99 responden yang memiliki riwayat nikah dini, dengan usia nikah termuda 10 tahun dan tertua 18 tahun. Pendidikan terakhir responden SD (69,7%) dengan pekerjaan sebagai “ibu rumah tangga”. Hal ini menunjukkan meskipun UU Perkawinan sudah diundangkan sejak tahun 1974 dan diubah di tahun 2019, namun masalah pernikahan dini masih tinggi, dan ini tentu mempengaruhi kinerja pemerintah untuk mencapai capaian Sustainable Development Goals (SDGs). Untuk itu perlu dilakukan penyuluhan dan pemantauan kepada orangtua, generasi muda serta lembaga masyarakat lainnya, agar pernikahan dini tidak lagi terjadi.

Peran Usaha Mikro Kecil Menengah (UMKM) dalam perekonomian Indonesia sangat penting dan merupakan pilar terpenting dalam peningkatan pertumbuhan  ekonomi Indonesia. Secara umum, khususnya dalam aspek keuangan, hanya sedikit UMKM yang mengalami perkembangan dalam kinerja keuangannya. Salah satu faktor yang menyebabkan hal tersebut terjadi adalah karena rendahnya kesadaran pelaku UMKM terhadap pentingnya pengelolaan keuangan. Pencatatan keuangan sangat penting bagi usaha apapun, namun pelaku UMKM sering mengabaikan hal tersebut, termasuk warga jemaat Gereja Kristen Pasundan (GKP) Klasis Jakarta sebagai pelaku usaha. Kegiatan dan kedisiplinan pencatatan semua pengeluaran dan pemasukan untuk mengontrol keuangan dalam bisnis sangat diperlukan. Berdasarkan hal tersebut dipandang perlu memberikan sosialisasi mengenai pentingnya manajemen keuangan bagi UMKM dan diharapkan dapat membantu warga jemaat Gereja Kristen Pasundan (GKP) Klasis Jakarta dalam melakukan pengelolaan  keuangan usahanya secara benar, disiplin, dan teratur. Pelaksanaan kegiatan pengabdian masyarakat ini bertujuan memberikan sosialisasi pentingnya manajemen keuangan  untuk pelaku UMKM dalam bentuk webinar dengan menggunakan aplikasi Zoom (online)).Secara keseluruhan kegiatan sosialisasi pentingnya manajemen keuangan untuk pelaku UMKM dapat dikatakan telah berhasil; yang dilihat dari target jumlah peserta, ketercapaian tujuan sosialisasi dan ketercapaian target materi yang telah direncanakan. Antusiasme peserta, support dari UKI dan Majelis  GKP Klasis Jakarta merupakan pendukung terlaksananya kegiatan PkM ini. Adapun manfaat yang diperoleh peserta dari kegiatan ini antara lain mereka dapat memahami pencatatan keuangan untuk UMKM dalam memajukan usahanya.

Introducción: la migración en algunos casos es el resultado de las desigualdades que se viven al interior de un país. Se ha considerado como un fenómeno que impacta el desarrollo económico, social y cultural de un país. Uno de los desafíos más relevantes del proceso migratorio es la cobertura y acceso universal en salud, que depende de la legalización del estado migratorio en el país receptor. Lo anterior, es de alta preocupación para los países debido a que la morbilidad materna y las complicaciones en la salud sexual y reproductiva son frecuentes en la población migrante, con mayor impacto en la incidencia de bajo peso al nacer y partos prematuros, así como también en los indicadores de mortalidad materna, neonatal e infantil. Objetivo: describir la tendencia de la migración y la salud materno-perinatal en Colombia entre el 2017 y el 2018. Materiales y métodos: investigación cuantitativa, descriptiva retrospectiva. La fuente de información es secundaria, por medio de la notificación individual semanal de casos al Sistema de Vigilancia en Salud Pública (Sivigila) de los eventos relacionados con la salud maternoperinatal: morbilidad materna extrema, mortalidad materna y mortalidad perinatal y neonatal tardía. Para el análisis de la información se establecen frecuencias absolutas y relativas. Para el análisis de la tendencia se utilizó Joinpoint versión 4.7, las diferencias significativas se establecieron con valor p<0,05, para un nivel de significancia del 95 %. Resultados: la tendencia de la tasa de migración neta tiene un comportamiento hacia el incremento; los eventos relacionados con la morbimortalidad materna, perinatal y neonatal tardía mostraron un aumento para la población migrante. Conclusiones: los hallazgos identificados hacen necesario que los países desarrollen estrategias para fortalecer la prestación de los servicios de salud y las políticas sociales dirigidas a la reducción de las condiciones de vulnerabilidad de dicha población y la intervención de los determinantes sociales de la salud para mitigar los resultados negativos en salud.
