Hardness Distribution of Heat-Affected Zones Made by Hardfacing on S690QL and S960QL Steel Plates
Authors: Terdik Gábor , Meilinger Ákos
Published: December 2024

In the case of hardfacing the usage of high-strength steels is more and more influential. Several applications can be found in the construction and demolition fields where the dynamic loading occurs beside the abrasive loading. Additionally, the applied steel strength is increased, and S690QL and S960QL base materials are used as base materials for hardfacing. These materials are quenched and tempered which means that the heat cycle of the welding / hardfacing can cause significant changes in the heat-affected zone. The heat cycles of hardfacing have a different effect on the heat-affected zone, than the welding. Additionally, there are sub-zones where 2 or 3 heat cycles cause softening or hardening due to microstructural changes. The properties of the heat-affected subzones basically depend on the heat input, the number of heat cycles, and the base material. In this research, the hardness of heat-affected zones was investigated in the case of S690QL and S960QL base material. Hardfacing was made by different heat inputs in the case of both materials and after comparison, differences are written. One butter layer and 3 hardfacing layers were made in each case by robotic MIG/MAG welding. Several heat-affected subzones are determined, so for exact results hardness maps were made in all cases by hundreds of hardness tests. These maps show perfectly the differences between the hardness of the zones and the differences between the dimensions of heat-affected zones. There are significant differences in the multiple times heated subzones according to heat input. In the case of S690QL, the hardening is more significant than the softening in the heat-affected zone, the S960QL shows the opposite reaction to the heat cycles of hardfacing. On the hardness maps, the differences between the hardfacing layers are almost visible, and it shows big drops in the hardness of these layers in all cases.
The Model is Designed Based on TPMS and Verified by Simulating Mechanical Properties
Authors: Li Long
Published: December 2024

The three-period minimal surface (TPMS) metal porous structure represents a novel design suitable for lightweight and multifunctional applications. This study designed three types of TPMS porous structures: Diamond, Gyroid, and Primitive, and investigated their deformation behavior through finite element simulation. Results indicate that the Gyroid structure demonstrates exceptional mechanical properties and energy absorption, achieving a strength limit of 186.44 MPa. The Gyroid porous structure exhibits a uniform layer-by-layer fracture pattern with a fracture zone at a 45° angle to the direction of pressure loading at 30% strain. Conversely, at 20% strain, the Diamond and Primitive porous structures exhibit initial shear band failures at the unit cell junctions.

Published: December 2024

This research aimed to evaluate the effects of ethyl acetate (EtOAc), dichloromethane (DCM), and butanol (n-BuOH) extracts from the roots of Ochna integerrima Merr on their in vitro anti-tyrosinase enzyme activity. The phytochemical composition of these extracts was analyzed using GC-MS/MS. The EtOAc extract was particularly rich in phenols (34.38%), followed by fatty acids and derivatives (18.09%), flavonoids and chalcones (16.94%), and steroids (14.20%). Six secondary metabolites were also isolated from the active fraction (EtOAc extract) using column chromatography. Their structures were elucidated through spectroscopic techniques, primarily 1D and 2D NMR, and cross-referenced with existing literature. The findings revealed that the EtOAc extract exhibited the most significant inhibitory activity against the enzyme tyrosinase, with an IC50 value of 0.106 mg/mL. While the DCM and n-BuOH extracts showed inhibitory effects at 0.1 mg/mL concentrations, with inhibition rates of 6.34% and 26.14%, respectively. These results suggest that the root extracts of O.integerrima have potential anti-tyrosinase properties that could be beneficial in the cosmetics industry. Further investigation is required to identify and isolate additional bioactive compounds of interest.

Published: December 2024

This study investigates the fabrication and potential application of novel sustainable energy materials from poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP)/amethyst composite films. Solution processing and casting techniques were employed to prepare these composites with varying amethyst content (0 – 0.5 phr). The film characteristics, including appearance, dispersion, morphology, density, and mechanical properties, were comprehensively analyzed. Optical microscopy (OM) revealed good dispersion of amethyst at low loadings, while higher loadings exhibited a tendency towards agglomeration. Notably, the mechanical properties of the composites improved with increasing amethyst content. Tensile strength increased from 5.57 to 13.04 N/mm², strain at break increased from 4.33 to 15.74%, and Young's modulus increased from 156.00 to 258.21 N/mm². The combined properties of PVDF-HFP and amethyst suggest their potential for application in sustainable energy generation. Future work will be directed towards exploring this possibility through further characterization relevant to energy applications.

Published: December 2024

NdFeB magnets were first developed in 1984 and are the most powerful permanent magnets that may possess energy products up to 60 MGOe. However, their working temperature and corrosion resistance are lower as compared to that of Alnico and SmCo magnets. Demand of NdFeB magnets recently has increased due to rapid growth of electrical vehicles. In this research work, NdFeB magnets developed through powder metallurgical technique are investigated for thermal effect on magnetic characteristics. The effect of increase in temperature on remanence, coercivity and energy product were measured using pulsed field magnetizer. Samples for testing were prepared from sintered bricks using wire cut machine. Demagnetization curves for the samples were measured at temperatures in the range of 20-110°C, and the results were analyzed. Decline in magnetic characteristics with temperatures is noted. Performance of the magnets with increase in temperature is essential to be analyzed specially for their use in high-speed motors.

Authors: Țunescu Traian , Ştefan Iulian , Socol Remus , Sîrbu Nicuşor Alin , Savu Ionel Danut
Published: December 2024

Runner blades of Kaplan turbines are elements subject to multiple mechanical and chemical stresses. For these reasons they suffer from pitting corrosion. Taking them out of production for repair involves relatively high costs, such actions can take up to 6 months. The identification of a technological or constructive solution for increasing pitting corrosion resistance is thus desirable. The paper proposes a combined technological and constructive solution for increasing corrosion resistance by pitting leading edges, the areas most affected by this type of corrosion. The experimental program highlighted the fact that the use of a similar material in terms of chemical composition and characteristics or a duplex stainless steel, deposited with linear energies lower than 1 kJ/mm, can lead to the generation of a layer that has good behaviour at pitting corrosion. The generated layer must have a thickness limited to 3 mm to avoid the appearance of additional vibrations at the blade level.
Pressure Distribution of Polyurethane Foam Based on Palm Oil Content
Authors: Kitisatorn Wanlop
Published: December 2024

This study explores the effect of varying epoxidized palm oil (EPO) content on the mechanical properties and pressure distribution of polyurethane (PU) foam. Polyurethane foams were synthesized with EPO concentrations of 25%, 50%, and 75%, and their morphologies, densities, hardness, compressive strength, and pressure distribution capabilities were analyzed. The results showed that increasing EPO content significantly affects the foam's cell structure, leading to variations in density and mechanical properties. PU foam with 50% EPO exhibited a more open-cell structure, resulting in lower density and hardness but compromised compressive strength. Conversely, foam with 75% EPO content demonstrated improved pressure distribution despite increased density and nonuniform cell sizes. These findings highlight the potential of using palm oil-based polyols to develop sustainable PU foams, balancing flexibility and mechanical strength for applications in cushioning and pressure relief materials. The study underscores the importance of optimizing EPO content to achieve desirable foam properties for specific applications.

Published: December 2024

Host preference in blood-feeding anopheline mosquitoes is crucial in determining malaria vectors. Using a PCR assay that targeted a portion of the Cytochrome b gene of five vertebrates, this study sought to investigate the blood meals of 30 field-caught Anopheles mosquitoes from two Northern Districts of Sri Lanka. Study revealed that blood meals of Anopheles culicifacies and Anopheles subpictus mosquitoes were exclusively from humans (23.3%) and goats (50%), and the remaining 26.6% were mixed blood meals. An. culicifacies (0.65) was more anthropophilic than An. subpictus (0.31), based on the Human Blood Index.  Single-host blood meals were more common in both An. culicifacies (70.6%) and An. subpictus (76.92%) than multiple-host blood meals. A significant association (p<0.05) was observed between the vertebrate source of the blood meal of the mosquito and the frequency of single and multiple-host blood meals taken. While the conventional multiplex PCR assay was more successful in identifying the source of multiple-host blood meals, the nested PCR technique effectively amplified the DNA of single-host blood meals. The mean DNA concentration of mixed-host blood meal extractions amplified by conventional PCR assay (121.8±37.3 ng/µL) was substantially greater (p<0.05) than that of the nested PCR (39.5±29.7 ng/µL). This study reveals important findings which are significant for further exploration into the vectorial capacity of An. culicifacies and An. subpictus, and consequently their transmission potential as malaria vectors in the area. This understanding of the feeding patterns of Anopheles vectors will be helpful for long-term planning and development of suitable, situation-specific malaria control measures in a country.

Authors: Njohjam Mundih N. , Nji Swirri S. , Nongse Ebsiy M.
Published: December 2024

Background: Post-stroke depression (PSD) negatively impacts the physical and mental well-being of stroke survivors. However, data on the prevalence and risk factors of PSD in African countries such as Cameroon are limited.Aim: This study aims to determine the prevalence and factors associated with PSD among stroke survivors at a hospital in Cameroon and inform clinical practice.Setting: The study was carried out in the Nkwen Baptist Hospital in the North West region of Cameroon.Methods: This was a hospital-based cross-sectional study. Stroke patients were systematically screened for PSD using the patient health questionnaire (PHQ-9). PSD was present if a patient scored ≥ 4 points on the scale. The multidimensional scale of perceived social support was used to assess the level of social support, the modified Rankin tool and Barthel index were used to assess functional independence, and the Fatigue assessment tool was used to assess post-stroke fatigue. A multivariate analysis was performed to identify factors associated with PSD.Results: A total of 103 patients were included in the study. The mean age was 55.55 ± 12.15. Most patients were males (58.25%). The mean depression score was 5.17 ± 6.26. The overall prevalence of PSD was 36.89%. A higher functional impairment, post-stroke fatigue, perceived social support, recent stroke and being divorced were all associated with high PSD scores.Conclusion: In this study, we found a high prevalence of PSD using a systematic screening approach, suggesting that systematic screening for PSD can lead to early detection and management.Contribution: Systematic screening for PSD in stroke patients can lead to early diagnosis and, consequently, early initiation of treatment. Integration of mental health support and care as part of the routine stroke is warranted.

Published: December 2024

Background:

Indoor air pollution is a critical global health concern and is associated with an increased incidence of respiratory infections. Despite the introduction of a subsidiary scheme, the adoption of clean fuel remains limited in rural India.

Objectives:

The current study investigated the fuel preferences and its association with participants characteristics, particulate matter (PM2.5) levels and respiratory complaints.

Materials and Methods:

A cross sectional study was done among rural women in Jodhpur, Rajasthan. A total of 480 women aged 15 years and above were included, and 120 households were selected using systematic random sampling technique for PM2.5 level assessment. Statistical analysis was done using Chi-square test, Fischer’s exact test, Mann–Whitney U test and Kruskal–Wallis test. Post hoc test with Bonferroni correction were used to identify differences between groups of fuel users.

Results:

The study revealed that 43.1% (207 participants) primarily used biomass as their fuel of choice, while 32.5% (156) primarily preferred liquified petroleum gas (LPG). Only LPG was used by 19.7% (95) of participants, and a small proportion of 4.58% (22) relied solely on mud stoves. There was significant association between education status, family income, years of cooking and fuel preferences among the participants (P < 0.05). The PM2.5 levels were higher among biomass users than LPG users.

Conclusion:

Study highlighted the intricate interplay between sociodemographic factors, cooking practices, PM2.5 concentration, and respiratory symptoms in rural settings, emphasizing the need for increased advocacy on LPG adoption to mitigate indoor air pollution-related health risks.

Published: December 2024

The global health crisis triggered by the SARS-CoV-2 in 2019, known as the COVID-19 pandemic, prompted vaccination drives worldwide, including in India, to address the crisis. However, vaccine hesitancy remains a significant challenge to achieving vaccination goals. Hence, we conducted a systematic review and meta-analysis during 2021–2023 to estimate the prevalence of COVID-19 vaccine hesitancy among adults in India and identify associated factors. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Quality assessment was performed using the Joanna Briggs Institute checklist. Pooled prevalence estimates were calculated using a random-effects model. A total of 265 articles were identified, of which 21 full-text articles were included in the review. The pooled estimated prevalence of COVID-19 vaccine hesitancy among adults in India was found to be 28% (95% confidence interval: 27–29). Subgroup analysis revealed variations in hesitancy rates across different states, with higher rates observed in Jammu and Kashmir (44%), West Bengal (49%), and Maharashtra (39%). Gender-based analysis indicated higher hesitancy among males (36%) compared to females (26%). Among different study populations, medical students showed the lowest hesitancy rate (13%), whereas the general population exhibited the highest (34%). The findings suggest that vaccine hesitancy remains a significant concern in India, with one in four adults expressing hesitancy toward COVID-19 vaccination. Hesitancy rates vary across states, genders, and study populations. Addressing the factors contributing to hesitancy, such as safety concerns, lack of evidence, and misinformation, is crucial to enhance vaccine acceptance.

Authors: Bakshi Jaimanti , Panda Naresh K. , Goyal Atul Kumar , Saini Jyoti , Prashant Shivji , Aggarwal Ganesh , Alnemare Ahmad K.
Published: December 2024

Background:

Trismus is the restricted mouth opening (≤35 mm) in oral cancer patients that may occurred due to the limited stretching of facial muscles because of tumor growth. Trismus can significantly affect the uptake and chewing of food which in turn cause nutrition depletion in cancer patients, thus affecting their quality of life and survival outcomes.

Objectives:

The present study was aimed to analyze the role of pretreatment trismus as a predictor of survival outcomes, including long-term survival and disease-free survival in oral cancer patients.

Materials and Methods:

A total of 38 oral cancer patients with restricted mouth opening were enrolled in the study. The trismus was assessed before the surgery using digital vernier caliper. The patients were then follow-up for survival outcomes over the period of 5 years. The survival outcomes were then correlated with the pretreatment trismus.

Results:

Poor long-term and disease-free survivals were found to be significantly associated with the high-grade pretreatment trismus. Patients with high grades of pretreatment trismus experienced early treatment relapse and high mortality.

Conclusions:

Pretreatment trismus was found to be a potential predictor of disease-free survival and overall long-term survival in oral cancer patients. It is recommended that a treatment protocol that could reduce the trismus should be adopted to enhance the survival outcomes of oral cancer patients.

Published: December 2024

Angiolymphoid hyperplasia with eosinophilia (ALHE) represents a rare benign vascular tumor characterized by distinctive endothelial proliferation accompanied by an eosinophilic infiltrate. This case study chronicles the clinical course of a 16-year-old male presenting with a persistent posterior auricular swelling first noted at 1 year of age. Despite initial diagnostic challenges and a misinterpretation via external fine-needle aspiration cytology suggesting a chronic inflammatory process, definitive diagnosis was achieved through excisional biopsy. Histopathological analysis revealed characteristic findings of ALHE, including lymphoid tissue interspersed with proliferating vessels lined by plump endothelial cells, and a prominent eosinophilic and occasional plasma cell presence. Differential diagnosis included conditions such as dermoid cysts, lipomas, and Kimura’s disease, highlighting the importance of precise histopathological assessment for accurate differentiation. Effective management typically involves complete surgical excision, underscoring the significance of meticulous diagnosis to guide appropriate therapeutic strategies and ensure favorable outcomes in managing such intriguing clinical presentations.

Authors: Sachidananda Roopa , Malipatil Alisha , Joshi Vikas , Hosamani Akila , Haranagatti Anusha , Kurugodiyavar Mahesh D.
Published: December 2024

Background and Aims:

Cesarean section is one of the most commonly performed surgeries in obstetrics. Various methods have been employed to assess postoperative pain. Surgical trauma causes acute phase response with neutrophilia and relative lymphopenia. Hence neutrophil lymphocyte ratio (NLR) can be taken as an objective tool to measure acute pain. The primary objective of the study was to evaluate the relationship between postoperative NLR and pain, which was assessed using visual analogue scale (VAS).

Material and Methods:

A prospective observational study was conducted on 120 pregnant women aged between 18 to 38 years belonging to American Society of Anesthesiologists Physical Status II undergoing elective cesarean section under subarachnoid block, in a tertiary care hospital over 18 months. Postoperatively pain was assessed using VAS. Blood samples were sent and NLR was calculated preoperatively and postoperatively. Injection diclofenac and tramadol was administered for postoperative pain and total doses of respective drugs were noted. The correlation between NLR and VAS was assessed using Spearman’s rank correlation analysis.

Results:

The postoperative NLR was higher than the preoperative NLR. There was significant correlation between VAS score and NLR score at 12th, 24th and 48th h [(Spearman’s rank correlation coefficient), r = 0.462, P < 0.001; r = 0.519 P < 0.001; r = 0.455 P < 0.001]. The diclofenac requirement was significantly high at 24 h among the repeat cesarean section patients (P = 0.023).

Conclusion:

The postoperative NLR correlated significantly with VAS. NLR can be used as a surrogate marker for pain assessment.

Authors: Kaur Kiranpreet , Kaur Tavleen , Kumar Prashant , Bhardwaj Mamta , Kaur Svareen , Singhal Suresh K. , Talwar Sakshi , Sandhu Paramjeet
Published: December 2024

Background and Aims:

The present study was planned to compare two devices, namely LMA Blockbuster and LMA Protector, as a conduit for endotracheal intubation. The study aimed to compare the first-pass success rate of blind intubation, time taken for successful intubation, and ease of intubation through both devices.

Material and Methods:

This prospective randomized study was conducted on 100 patients of either sex aged 18–60 years, belonging to ASA physical status I–II, with 50 patients in each group (group B – LMA Blockbuster, and group P – LMA Protector). All the patients received general anesthesia. The primary objective was to compare the success rate, ease of blind tracheal intubation, time taken for intubation, and number of attempts. Secondary objectives included assessing the success of supraglottic device (SAD) placement, oropharyngeal seal pressure, and hemodynamic changes.

Results:

The insertion time of the SAD was 8.18 ± 3.66 and 10.94 ± 6.66 s for groups B and P, respectively. The SAD was placed on the first attempt in 96.0% of patients in group B and 88% of patients in group P. The total time taken for successful intubation was comparable between the groups (P = 0.239). The ETT was placed in the first attempt in 88% and 78% patients in group B and group P, respectively (P = 0.8).

Conclusions:

We conclude that LMA Blockbuster and LMA Protector are both comparable and good intubating devices in terms of ease and success rate of intubation. However, LMA Blockbuster outperforms LMA Protector in terms of ease of insertion of SADs.
Comparison of jaw thrust and backward-upward-rightward pressure (BURP) manoeuvre with conventional technique on glottic visualization and intubation characteristics using C-MAC video-laryngoscope
Authors: Jain V Keerthi , Seth Anita , Kumar Rakesh , Yazhini A A , Kohli Santvana
Published: December 2024

Background and Aims:

Traditionally various methods have been employed to improve glottic visualization during laryngoscopy, namely backward-upward-rightward pressure (BURP) and jaw trust with promising results. The current study aims to compare these maneuvers for the enhancement of glottic visualization during video laryngoscopy.

Material and Methods:

In this prospective randomized study in 120 adult patients with normal airways, C-MAC® laryngoscopy was performed under general anesthesia (GA). Images of the glottis with conventional laryngoscopic technique, using BURP maneuver and jaw thrust were acquired, and Cormack–Lehane (CL) grading, percentage of glottic opening (POGO) score, and approximate glottic area were recorded from the images. Subsequently, patients were divided into three equal groups–in group C, the trachea was intubated using conventional laryngoscopic technique, in group B, BURP was used, and in group J, jaw thrust was used. Intubation time, ease of intubation, number of intubation attempts, incidence of airway trauma, and postoperative sore throat were noted.

Results:

Both jaw thrust and BURP maneuvers improved CL grading, POGO score, and glottic area significantly as compared to the conventional laryngoscopic technique. CL grading and POGO score were better with BURP than with jaw thrust; however, the glottic area improved more with jaw thrust. Jaw thrust also resulted in statistically significant lower intubation time and better ease of insertion score. Intubation was successful in the first attempt in all patients and there was no airway trauma and postoperative sore throat.

Conclusion:

Both BURP and jaw thrust maneuvers result in better glottic visualization. Jaw thrust provides lower intubation times, better ease of intubation scores, as well as a higher visualized glottic area than BURP.
Taming posterior polar cataract – My way of small incision cataract surgery
Authors: Soumya PP
Published: December 2024

Posterior polar cataracts (PPCs) present a challenging situation for surgeons due to the high likelihood of intraoperative issues such as posterior capsular rupture and aphakia. It is widely recognized that patients with PPC typically have a thin posterior capsule, which is densely attached to the cataract, making it fragile. Although various surgical techniques have been suggested for addressing this specific type of cataract, achieving successful outcomes without complications remains a significant challenge for many surgeons. In developing countries, aspiring surgeons may not have extensive experience with phacoemulsification. This study explores the safe application of small incision cataract surgery in such cases.
Oculocardiac reflex during DCR surgery-An unusual presentation
Authors: Mittal Bharat , Singh Arun Kumar
Published: December 2024

Oculocardiac reflex (OCR) is a physiological response of the heart to physical stimulation of the eye or ocular adnexa. It is defined by the appearance of bradycardic arrhythmia during ocular surgery. It is defined as decrease in heart rate from baseline values by atleast 10% to 20%. We report an unusual presentation of oculocardiac reflex during DCR surgery in a 65-year-old female while suturing the muscle layer and which gets resolved as soon as the sutures are removed. OCR during DCR surgery has been rarely reported in the literature and here we present one such case.
Usefulness of spectral domain optical coherence tomography in assessing the clinical course of idiopathic intracranial hypertension: A case series
Authors: Viswanath Vrinda , Neena R
Published: December 2024

To assess the clinical corelation of optical coherence tomography and the clinical course of idiopathic intracranial hypertension with a case series of 4 patients diagnosed with IIH and presented to a tertiary eye care centre over a 1 year period (2020-2021). Ethics committee approval taken on 12th Oct 2020. A detailed history and complete ophthalmic examination including best corrected visual acuity (BCVA), color vision, pupils, dilated fundus examination, visual fields, and OCT were done on all visits. OCT PP RNFL thickness was found to correlate with an increase and decrease in disk edema; however, in the presence of optic atrophy, mGCL was found to be a better predictor of ongoing axonal damage. A valid relationship was found between the patient’s clinical course, visual field changes as well as the RNFL and GCL parameters in OCT. Serial OCTs have a useful role in predicting the course and prognosis of the disease and can aid in altering treatment modalities.

Published: December 2024

Severe acute respiratory syndrome corona virus (SARS-Cov 2) is known to have neuro-ophthalmological manifestations such as optic neuritis, papillophlebitis, papilledema, visual disturbance associated with posterior reversible encephalopathy syndrome, and vision loss caused by stroke, Miller Fisher syndrome, Adie’s pupils, ocular myasthenia gravis, nystagmus eye movement disorders, and cranial neuropathies like third and sixth nerve palsies. Sixth nerve palsy in adults is mostly attributable to microvascular ischemia and trauma. Research suggests that SARS- COV 2 infection can result in inflammatory nerve damage due to aberrant immune response leading to neuropathy. We report a case of a 42-year-old man presenting with a unilateral abducens nerve palsy following Covid-19 infection treated with a course of steroids leading to faster recovery.
Determination of cefuroxime in human blood and urine using UHPLC-MS/MS and its application to stability study of cefuroxime over 278 days
Authors: Nowak Karolina , Zawadzki Marcin , Szpot Paweł
Published: December 2024

Purpose: Forensically, the widespread use of antibiotics necessitates methods for their detection in biological materials to ascertain their role in adverse reactions or fatalities. Given the need to conduct toxicological studies on materials stored for extended periods under various temperature conditions, research on antibiotic stability in biological matrices over such durations is crucial for accurate toxicological assessments.

Methods: The stability of cefuroxime in blood and urine was determined for 278 days at three different temperatures: -15°C, +4°C, +23°C. The analyses were conducted using ultra-high-performance liquid chromatography coupled with triple-quadrupole tandem mass spectrometry. Results: The method met all validation requirements. This study also describes the results of the thermal stability of cefuroxime. Cefuroxime showed the greatest stability at -15°C and was highly unstable at room temperature (+23°C) in all types of studied biological matrices.

Conclusions: The study confirms instability of cefuroxime in blood and urine samples. Therefore, the analysis of this antibiotic in biological matrices for purposes such as forensic toxicology should be performed as soon as possible after sampling to avoid decline in concentration. In cases of prolonged material storage, the concentrations should be cautiously interpreted in the prepared expertise.
Polityka bezpieczeństwa w zakładach karnych wobec wyzwań związanych ze starzeniem się osadzonych
Authors: Malec Norbert
Published: December 2024

Współczesny świat często wypiera starość i problemy jej towarzyszące. Gloryfikuje natomiast młodość, piękno i zdrowie, zapominając często, że mają one swój kres. Taki stan rzeczy sprawia, że osoby starsze są często marginalizowane przez społeczeństwo, a szczególnie jest to widoczne, jeśli chodzi o seniorów, którzy przebywają w różnych miejscach odosobnienia w tym również w jednostkach penitencjarnych. Jak pokazują dane statystyczne co roku wzrasta liczba osób w wieku senioralnym przebywających w izolacji penitencjarnej. Od kilku lat jest to nowe wyzwanie dla służby więziennej z punktu widzenia wykonania kary i działań podejmowanych na rzecz bezpieczeństwa podejmowanych na rzecz tej kategorii więźniów.
Celem artykułu jest analiza wpływu starzenia się populacji więźniów na politykę bezpieczeństwa w polskich zakładach karnych. W szczególności chodzi o ocenę, w jaki sposób zmieniające się potrzeby osadzonych w wieku senioralnym wpływają na organizację, infrastrukturę oraz procedury związane z zapewnieniem bezpieczeństwa w jednostkach penitencjarnych. Jak starzenie się populacji więźniów wpływa na realizację polityki bezpieczeństwa w polskich zakładach karnych? Czy obecne procedury i działania są adekwatne do wyzwań związanych z obsługą więźniów w wieku senioralnym? Odpowiednio do postawionego problemu badawczego sformułowano hipotezę, która zakłada, iż starzenie się populacji osadzonych wymusza modyfikację polityki bezpieczeństwa w zakładach karnych, zarówno w zakresie infrastruktury, jak i organizacji pracy personelu. Obecny system wymaga dostosowania do specyficznych potrzeb więźniów senioralnych, aby skutecznie zapewnić bezpieczeństwo oraz ochronę zdrowia i życia tej grupy. W celu odpowiedzi na problem badawczy oraz weryfikacji hipotezy zastosowano metody badawcza takie jak krytyczna analiza literatury, która dotyczyła przeglądu istniejących badań, raportów i dokumentów dotyczących demograficznych zmian w populacji więźniów a także analiza aktów prawnych zawierających przepisy dotyczące funkcjonowania zakładów karnych, szczególnie tych związanych nz prawami osadzonych, standardami bezpieczeństwa i opieką zdrowotną. Dokonano również analizy zależności między różnymi elementami systemu penitencjarnego, w tym polityką bezpieczeństwa, strukturą organizacyjną i potrzebami więźniów w wieku senioralnym.

Refleksi Moral dan Implikasi Etis dari LGBT, Aborsi, dan Euthanasia dalam Konteks Modern
Authors: Krikhoff Rudy Arianto
Published: December 2024

Social transformation in modern society presents significant challenges for the church in responding to moral and ethical issues, particularly those related to LGBT, abortion, and euthanasia. These issues not only challenge the church's established views on human dignity and God's authority over life but also demand deeper reflection within the context of Christian theology. This article aims to analyze the moral reflection and ethical implications of these three issues, with the goal of understanding how the church can respond to social changes without neglecting essential Biblical principles, while remaining relevant amidst the changing times. This study uses a qualitative method, involving theological literature review as well as interviews with church leaders. The literature review highlights contemporary theological perspectives on morality, love, and justice in relation to LGBT, abortion, and euthanasia. Meanwhile, interviews with church leaders provide practical insights into how moral teachings are applied in navigating social dynamics. The results of this study show that the church must adopt a balanced approach: upholding Biblical moral principles, such as love and respect for life, while also engaging in a more inclusive and compassionate dialogue with society. This approach allows the church to remain relevant in addressing moral and ethical issues in the modern era, without losing its theological integrity.
 
Transformasi sosial dalam masyarakat modern membawa tantangan signifikan bagi gereja dalam merespons isu-isu moral dan etis, khususnya terkait LGBT, aborsi, dan eutanasia. Ketiga isu ini tidak hanya mengguncang pandangan gereja yang telah mapan tentang martabat manusia dan otoritas Tuhan atas kehidupan, tetapi juga menuntut refleksi yang lebih mendalam dalam konteks teologi Kristen. Artikel ini bertujuan untuk menganalisis refleksi moral dan implikasi etis dari ketiga isu tersebut, dengan tujuan memahami bagaimana gereja dapat merespons perubahan sosial tanpa mengabaikan prinsip-prinsip Alkitabiah yang esensial, namun tetap relevan di tengah perkembangan zaman. Penelitian ini menggunakan metode kualitatif, meliputi kajian literatur teologis serta wawancara dengan tokoh-tokoh gereja. Kajian literatur menyoroti pandangan teolog kontemporer tentang moralitas, kasih, dan keadilan dalam kaitannya dengan LGBT, aborsi, dan eutanasia. Sementara itu, wawancara dengan para pemimpin gereja memberikan perspektif praktis mengenai bagaimana ajaran moral diterapkan dalam menghadapi dinamika sosial. Hasil penelitian ini menunjukkan bahwa gereja harus mengambil pendekatan yang seimbang: mempertahankan prinsip-prinsip moral Alkitabiah, seperti kasih dan penghormatan terhadap kehidupan, sambil membuka dialog yang lebih inklusif dan penuh kasih dengan masyarakat. Pendekatan ini memungkinkan gereja tetap relevan dalam merespons isu-isu moral dan etis di era modern, tanpa kehilangan integritas teologisnya.
COMPRESSION METHODS FOR SATELLITE IMAGES USING WAVELET TRANSFORM AND PERFORMANCE EVALUATION
Authors: Öz İbrahim
Published: December 2024

Research on image compression spans various fields, focusing on achieving efficient compression while preserving a specific image quality. Satellite images captured by observation satellites possess unique characteristics distinct from other images. Analyzing these specific qualities is decisive, leading to the proposal of tailored compression methods and transforms suitable for satellite image characteristics. This study comprehensively assesses the performance of six well-known compression methods in the literature, utilizing wavelet transform and metrics such as bits per pixel (BPP), compression ratio (CR), Peak Signal-to-Noise Ratio (PSNR), calculation time (CT), and Mean Squared Error (MSE). The compressed satellite images, generated through six methods and the Coif3 wavelet, are systematically compared and evaluated using performance metrics. The average values obtained for all six methods are 96.37%, 47.10 dB, and 7.92 seconds for CR, PSNR, and CT receptively, while WDR exhibits CR at 96.36%, PSNR at 48.84 dB, and CT at 6.58 seconds. The findings indicate that the Wavelet Difference Reduction (WDR) compression method utilizing the Coif3 wavelet outperforms others when considering all parameters together. We suggest that operators and manufacturers choose wavelet transform and WDR compression methods for effective compression of observation satellite images to achieve optimal results.

Job Satisfaction Audit in Hospital: Qalitative Case Study
Authors: Holá Jana , Michková Adéla , Kopecká Monika
Published: December 2024

Introduction: The shortage of healthcare professionals, their turnover, and the risk of burnout are critical issues in healthcare organizations, impacting the quality and safety of care. This study, based on contractual research, aimed to identify factors influencing employee satisfaction in new hospital facilities.
Aim: This article presents an audit of job satisfaction using the JD-R model in a healthcare facility to improve employee stability and well-being, thereby enhancing care quality and safety. It aims to showcase a methodological approach applicable in healthcare management and other services.
Method: The extended JD-R model (Job Demands-Resources model) was used as the theoretical framework. The analysis of negative and positive factors that influence job satisfaction was based on data collected from anonymous semi-structured interviews. Thematic and narrative analysis, as well as the study of internal documents, was also used and evidence-based results were presented in a final synthesis.
Results: The methodological approach delivered valuable findings for improving care. Key positive factors influencing job satisfaction included prospects of permanent employment and salary levels. Significant negative factors were concerns about personal safety and dissatisfaction with medical staffing.
Conclusion: The study’s final report, presented to top management, outlined the positive and negative factors affecting job satisfaction and well-being. Management expressed willingness to act on the findings and provided specific examples during the results presentation. While the results’ transferability is limited, the methodological approach is inspiring and applicable in healthcare organizations.
Private entrepreneurship in Ukraine
Authors: Place Joseph Jack , Everett Judas
Published: December 2024

This article deals with the question of what kind of philosophical principles guide private entrepreneurship in Ukraine, and what are its strengths and weaknesses. There is evidence that a history of entrepreneurship is present in Ukrainian history. However, this private entrepreneurship has mostly eked out an existence despite overwhelmingly unfavourable odds. The question of guiding principles has had little time or space devoted to it. Nevertheless, there is a clear tendency to respond to corruption, and any other challenges, with increasing deregulation and removal of rights and protections. While encouragement of business ownership is desirable, the policies that Ukraine is undertaking create as many problems as they solve, are harmful to workers, entrepreneurs, for society, and stability – indicating that this is not a viable long-term strategy.
Criticism of the communist legacy in Croatia on the pages of the magazines Republika Hrvatska and Nova Hrvatska in the period 1989-1991
Authors: Krašić Wollfy
Published: December 2024

This paper presents and analyses the texts of selected Croatian émigrés, who in the early 1990s transferred their activities to the newly founded Republic of Croatia and called for a decisive break with communist practices and mentality in the moments of Croatia’s transition from a communist to a democratic system. The aim of the paper is to enrich the findings of political ideas and visions in Croatia at the end of the 20th century and to show that some of the Croatian émigrés did not limit themselves to activities aimed at the creation of an independent Croatian state, but also offered solutions for its upbuilding as a truly democratic state.
