Authors: Si Kai-Wen , Wang Qing-Wen 
Published: April 2024

In this paper, we investigate the necessary and sufficient conditions for solving a dual split quaternion matrix equation AXB = C, and present the general solution expression when the solvability conditions are met. As an application, we delve into the necessary and sufficient conditions for the existence of a Hermitian solution to this equation by using a newly defined real representation method. Furthermore, we obtain the solutions for the dual split quaternion matrix equations AX = C and XB = C. Finally, we provide a numerical example to demonstrate the findings of this paper.

Relevance. Plaque-induced gingivitis represents the initial phase of periodontal diseases and a significant medical and social challenge within global healthcare frameworks, particularly prevalent among younger people.Demographics. This prevalence arises from its multifactorial etiology, complex developmental mechanisms, and notable pathogenetic features, most evidently microcirculatory disruptions leading to tissue hypoxia. Addressing these pathological conditions requires the development of novel diagnostic methodologies and therapeutic interventions to prevent further complications.Materials and methods. The study encompassed 54 subjects with an average age of 22.5 ± 1.7 years. The control group included 34 participants (GroupI), and the comparison group 20 participants (Group II). Group II received vacuum laser therapy in conjunction with Mexidol-based dressings, noted for their antihypoxant and antioxidant properties.Results. Evaluations conducted post-treatment indicated enhancements in both arterial and venous capillary functions. Amid the antioxidant and antihypoxant treatment regimen, capillary diameters were reduced to match those observed in the control group.Conclusion. Regimen implemented in this study was clinically and functionally effective in a combined treatment protocol involving vacuum laser therapy on periodontal tissues of plaque-induced gingivitis patients. This regimen is recommendable as a corrective measure for microcirculatory disturbances within the scope of managing inflammatory periodontal diseases.

Authors: Shameela Alika , Sulistiadi Wahyu 
Published: April 2024

Background: Patient safety is an important discipline for improving the quality of hospital health services. By establishing a positive patient safety culture in a hospital, the commitment to create a safer patient safety culture as an act to reduce incidents is also higher. One of the supporting factors of patient safety culture is teamwork. Teamwork is an effort to work with other people cooperatively as a part of the group. Hospital "X" is a hospital located in South Jakarta that in carrying out their mission to improve the quality of their health services, requires a positive patient safety culture. Objective: This research aims to analyze the role of teamwork in building a safer patient safety culture at Hospital “X". Method: This research is qualitative research with a case study approach using in-depth interviews with 4 informants. The research was conducted in August- September 2023. Result: The results of the research show the patient safety culture in Hospital "X". Hospital Hospital "X" already has a fairly positive patient safety culture by having a patient safety program and good teamwork, but still needs more evaluation on its implementation. In addition, teamwork has an important role in building a patient safety culture in terms of team effectiveness, support for staff, as well as regular reviews and evaluations of the team. Conclusion: The patient safety program at Hospital “X” already exists and has been running quite well. The factors contributing are teamwork and collaboration, but the effectiveness of teamwork is still not quite effective. Recommendation: Therefore, a tiered guidance supervision system is recommended along with a regular seminar or training and support management
Estimation of the band alignment of metal/AlScN interfaces by hard X-ray photoelectron spectroscopy
Authors: Nakada Gen , Kirihara Yoshiharu , Yasui Akira , Kakushima Kuniyuki , Nohira Hiroshi 
Published: April 2024

Abstract
This paper describes the band alignment of metal/AlSc(O)N measured using hard X-ray photoelectron spectroscopy. The band offset was determined by using the difference in binding energy from the core level to the upper edge of the VB, and the bandgap was determined from the energy loss spectrum of photoelectrons. The introduction of oxygen into AlScN to make AlScON decreases both the conduction band and VB offsets. The change in barrier height of the metal/AlScN structure is very small relative to the difference in the work function of the metal. This suggests that Fermi-level pinning occurs at the metal/AlScN interface.
Gate reliability enhancement of p-GaN gate HEMTs with oxygen compensation technique
Authors: Wang Chengcai , Chen Junting , Jiang Zuoheng , Chen Haohao 
Published: April 2024

Abstract
Improved p-GaN gate reliability is achieved through a simple oxygen compensation technique (OCT), which involves oxygen plasma treatment after gate opening and subsequential wet etching. The OCT compensates for the Mg acceptors near the p-GaN surface, leading to an extended depletion region under the same gate bias and thus reducing the electric field. Furthermore, the Schottky barrier height also increases by OCT. Consequently, suppressed gate leakage current and enlarged gate breakdown voltage are achieved. Notably, the maximum applicable gate bias also increases from 4 V to 8.1 V for a 10 year lifetime at a failure rate of 1%.
Tax Compliance Procedures and Tax Compliance of Small and Medium Enterprises in Thika Town, Kiambu County, Kenya
Authors: Kamau Stephen , Wanjohi Festus 
Published: April 2024

Small and medium-sized enterprises are an important part of the taxpayer population in any country around the globe. Their taxation usually poses a number of challenges. They are numerous but contribute relatively little to the state coffers, while often absorbing a large share of scarce tax administration resources much needed elsewhere in administering the tax system. The purpose of the study is to investigate the effect of tax procedures complexity on tax compliance of Small and Medium Enterprises in Kiambu County. The theories guiding the study include the ability-to-pay taxation theory, Prospect theory of taxation, and the Allingham and Sandmo theory. This study adopted a cross-sectional survey design because the design is best suited for finding out the prevalence of a phenomenon, situation, problem, attitude or issue, by taking a cross-section of the population as it stands at the time of the study. The target population comprised of 3616 registered businesses in Kiambu County. A sample of 385 SMEs managers and owners were selected using stratified random sampling method. Primary data was collected with structured questionnaires. Secondary data was collected by use of secondary data collection sheet to supplement the primary data. A pilot study was undertaken on 38 SMEs to test the reliability and validity of the questionnaire. The tool of analysis that was used for this study was Statistical Package for Social Sciences version 28. Correlation and multiple linear regression analyses was used to determine the relationship between the tax code complexity and tax compliance among small and medium sized enterprises in Kiambu County. Before taking part in the study, top management of the SMEs were asked for their informed consent in order to ensure that the research is carried out in a suitable setting free from internal interferences and influences. The study findings established that tax filing procedure, tax registration, tax remittance and tax rate determination have significant effect on tax compliance of small and medium enterprises. It is concluded that the procedures for online tax filing provided by the tax agency are a bit complex to understand by small and medium enterprises. The study concludes that tax registration by small businesses is received positively and not misconstrued as been punitive. Further, the tax agency should roll out tax filing education programs to small traders to make it easy to file taxes and the tax filing period should be reviewed to be flexible. The tax collector should revise the current compulsory requirements to register for tax by SMEs as it was found to affect tax compliance.
Organizacja Kościoła prawosławnego w II Rzeczypospolitej (1918-1921)
Authors: Borkowski Andrzej 
Published: April 2024

Polski rząd w latach 1918-1921 zmierzał do sformowania wyższej władzy cerkiewnej. Stworzył podstawy pod misję dyplomatyczną w Moskwie i Stambule, dążąc do usamodzielnienia administracyjnego i oddzielenia prawosławia w Polsce od wpływów Rosji sowieckiej. W pierwszym etapie organizacji diecezjalnej Kościoła prawosławnego w Polsce skrystalizowały się określone potrzeby, mianowicie powołanie wyższej władzy cerkiewnej i zadbanie o właściwe relacje z polskimi władzami. Kościołem prawosławnym w Polsce kierowały różne wyższe władze cerkiewne: ukraińskiego synodu biskupów, patriarchatu moskiewskiego czy synodu hierarchii rosyjskiej za granicą. Ze swej strony polskie władze nie zgadzały się na ingerencję zewnętrznych zarządów cerkiewnych. W powyższej sytuacji należało stworzyć niezależny wyższy zarząd cerkiewny na miejscu w celu uregulowania życia cerkiewnego w Polsce i obrony interesów cerkiewnych w relacjach z polskim rządem.

The glass finds from the Vetricella site (9th-12th c.)Introduction
Authors: Gratuze Bernard , Castelli Letizia Maria , Bianchi Giovanna 
Published: April 2024

We examine here the glass finds from the Vetricella site. This site, investigated during the ERC-Avanced nEU-Med project (www.neu-med.unisi.it ) is interpreted as the centre of the royal curtis of Valli attested in documentary sources from 937. During the excavation, a large number of glass objects dated from the 4th to the 12th centuries were unearthed. The compositions of the early mediaeval Vetricella glass vessels (beakers, goblets, bottles, ampoules/vials), are studied and compared with those of similar finds from various other European sites. With the exception of one glass bottle, made with Syro-palestinian plant ash soda glass, all the other studied glasses belong to Antique or Late-Antique natron glass groups (Mn- and Sb-decolorized, Foy 2 and HIMT). All these objects illustrate the recycling practices of Antique and Late Antique glass in Europe as they are described by Theophilus for the 11th and 12th centuries.

Authors: Lenka Abhishek , Sundaravadivel Pandarisamy , Christopher Rita , Arumugham Shyam S. , Hegde Shantala , Yadav Ravi , Pal Pramod Kumar 
Published: April 2024

Objective:
Homer1, a postsynaptic protein coded by the HOMER1 gene, presumably has a role in homeostatic plasticity that dampens neuronal responsiveness when the input activity is too high. HOMER1 polymorphism has been studied in major psychiatric disorders such as schizophrenia. The objective of this study is to investigate if polymorphisms of the HOMER1 gene are associated with psychosis in Parkinson’s disease (PD-P).

Methods:
One hundred patients with Parkinson’s disease (PD) and 100 healthy controls were enrolled consecutively in a PD-P biomarker study at the National Institute of Mental Health and Neurosciences, Bangalore, India. Of the 100 PD patients, 50 had psychosis (PD-P) and 50 did not have psychosis (PD-NP). Two single-nucleotide polymorphisms of HOMER1 (rs4704559 and rs4704560) were analyzed from the DNA isolated from peripheral blood. The allele and genotype frequencies in the PD-P and PD-NP groups were compared.

Results:
Analysis of HOMER1 rs4704560 revealed a significant difference in both genotype and allele levels between PD-P and PD-NP groups. There was an overrepresentation of T-allele (42% vs. 16%; P < 0.001) and TT genotype (24% vs. 6%; P < 0.001) in the PD-P group compared to PD-NP group. There was no significant difference between PD-P and PD-NP groups when various genotypes and allele frequencies related to HOMER1 rs4704559 were compared.

Conclusion:
PD-P is probably associated with overrepresentation of T-allele of HOMER1 rs4704560, and larger studies are warranted to confirm our results.
Combination of Remimazolam and Remifentanil for Procedural Sedation and Analgesia in a Patient with Morbid Obesity Undergoing Gastrointestinal Endoscopy under Continuous Positive Airway Pressure: A Case Report
Authors: Lin Chih-Wei , Cheng Kuang-I , Wu Zhi-Fu 
Published: April 2024

Abstract
Sedation in patients with morbid obesity undergoing gastrointestinal endoscopy (GIE) frequently causes respiratory depression. Remimazolam, a gamma-aminobutyric acid receptor agonist, is safer than propofol as it has fewer cardiovascular and respiratory adverse effects. We report a case of successful GIE under sedation and analgesia with a combination of remimazolam and remifentanil, respectively, in a patient with morbid obesity experiencing obstructive sleep apnea (OSA). Remimazolam ensured safe sedation, preventing complications such as respiratory depression and hypotension. Dose adjustment of remifentanil can minimize its adverse effects. Therefore, the combination of remimazolam and remifentanil is a promising choice for performing GIE in patients with morbid obesity and OSA.
Antimalarial potential of Kerala Ayurvedic Water “Pathimugam”
Authors: Kaushik Naveen Kumar , Sahal Dinkar 
Published: April 2024

Background & objectives:
The persistent threat of drug resistant malaria demands new cures. Low prevalence of malaria in the Indian state of Kerala compared with other proximal states led us to explore if there is any traditional practice in Kerala which may confer protection against malaria. In this context, our attention was drawn to “Pathimugam” i.e., Ceasalpinia sappan whose heartwood is used to prepare a red aqueous extract which is a uniquely popular drink all over Kerala.

Methods:

Aqueous and methanolic extracts of various organs of C. sappan were prepared and tested against Plasmodium falciparum grown in vitro culture using SYBR Green-I assay. The cytotoxicity of active extracts/fractions was studied using mammalian HeLa cell line. In vivo efficacy was determined using Plasmodium berghei ANKA infected mice.

Results:
The highest antiplasmodial activities in the alcoholic and aqueous extracts were observed in leaf methanolic extract (IC 2 μg/ml) and heartwood aqueous extract (IC 12.5 μg/ml). C. sappan extracts were equipotent against both chloroquine sensitive Pf3D7 and resistant Pf INDO strains and showed suppression of % parasitemia in P. berghei infected mice. Activity guided chromatographic fractionation of aqueous wood extract led to the fortification of antiplasmodial activity (IC 5 μg/ml).

Interpretation & conclusion:
Our results establish the antiplasmodial potential of C. sappan and suggest that its regular use might have prophylactic or curative actions that may assist in keeping check on malaria in the Indian state of Kerala.
A comparative study on the vector competence of Anopheles stephensi from geographically distinct malarious and non-malarious urban areas in India to the malarial parasite, Plasmodium vivax
Authors: Ravindran John , Eapen Alex 
Published: April 2024

Background & objectives:

Anopheles stephensi is responsible for the transmission of malaria in urban areas. Vector competence of An. stephensi from a non-malarious (Coimbatore) and highly malarious (Chennai) urban area were investigated to find out the reason for the non-transmission of malaria in Coimbatore.

Methods:
Vector competence (Susceptibility/refractoriness) of An. stephensi mosquitoes from Chennai (Malarious) and Coimbatore (Non-malarious), Tamil Nadu, India to Plasmodium vivax (Chennai) were investigated. Bioassays were carried out concurrently in both these strains by artificial membrane feeding technique using the same malaria infected blood. An. stephensi were dissected to observe infection in the midgut and salivary glands. The parasite infection, oocyst and sporozoite positivity rate, the oocyst load, correlation between male-female gametocyte ratio and infection, and Survival Analysis of parasitic stages during sporogony were analyzed and compared.

Results:
The overall infection rate was 45.8 and 41.2 per cent in Chennai and Coimbatore. Oocyst count ranged from 1-80 and 1-208 respectively and not statistically significant. Oocyst positivity was high from Day 8-21in both strains. The Mean Survival Day (MSD) for oocyst was Day 14 in both strains. Sporozoite was observed in four experiments in each of the strains and the MSD for sporozoites was Day 20 and Day 17 in Chennai and Coimbatore.

Interpretation & conclusion:

An. stephensi of Chennai and Coimbatore are equally susceptible to P. vivax infection and the non-transmission of malaria in Coimbatore can be attributed to external factors such as the presence of preferential breeding habitat, vector density, vector survival, and weather. The only difference observed was the comparatively shortened oocyst maturation time in the Coimbatore strain which requires further investigation.

Published: April 2024

Abstract:

PURPOSE:
The objective of the study was to describe the visual characteristics of patients with retinochoroidal coloboma attending the low-vision care clinic of a tertiary eye care hospital.

METHODS:
The clinical records of all patients attending low-vision care clinic between January 2016 and December 2016 were retrospectively reviewed. The data analyzed were demographics, occupation, type of coloboma, visual demand, visual acuity, and prescription of low-vision devices (LVDs). The colobomatous eyes were categorized as simple coloboma and coloboma with microphthalmos.

RESULTS:
Of the 100 patients, 164 eyes were diagnosed with retinochoroidal coloboma. Among patients, 70% were males and 30% were females. The mean age range was 23.58 ± 13.15 years and 21.77 ± 11.97 years in patients with simple coloboma and coloboma with microphthalmos, respectively. Type 1 coloboma and myopic refractive error were found to occur more frequently. Dome magnifiers (39.58%), handheld (16.66%), and aspheric spectacle magnifiers (14.5%) were the frequently prescribed LVDs.

CONCLUSION:
There is no or limited treatment for most of the visually impaired patients; thus, there is an important role of low-vision professionals in helping people with low vision to perform their routine activities.

Published: April 2024

Abstract
Monkeypox (Mpox) is an acute febrile rash illness caused by the Mpox virus. The ongoing international outbreak since mid-2022 has spread worldwide, including Taiwan. Ocular involvement in Mpox infection is uncommon, including external and ocular surface lesions. Here, we describe a man who developed unilateral blepharoconjunctivitis and preseptal cellulitis, followed by the appearance of skin symptoms 6 days after the ocular manifestations. Samples taken from his oropharynx and skin lesions tested positive for the Mpox virus through a polymerase chain reaction test. He was hospitalized for isolation with topical lubricant, antibiotic, and acyclovir eye ointment until the skin lesions healed. However, on the day of discharge, punctate epithelial keratitis was observed in the same eye. The corneal lesion also tested positive for the Mpox virus. His keratitis progressed to dendritic ulceration, and treatment with tecovirimat was initiated. Initially, his corneal ulcer responded well to tecovirimat, but 12 days later, it deteriorated along with cells in the anterior chamber. To treat his condition, low-dose steroid and ganciclovir eye drops were administered. Eventually, the patient experienced resolution of the corneal lesion, leaving a scar.
