Vulvar cancer is a rare neoplasm. Risk factors for the development of vulvar cancer include advanced age, human papillomavirus infection leading to high-grade squamous intraepithelial lesions, smoking, inflammatory conditions affecting the vulva, immunodeficiencies such as human immunodeficiency virus infection, and the presence of well-differentiated vulvar intraepithelial neoplasia (VIN) in patients from 65 to 70 years. VIN may be asymptomatic or present with a mixed variety of symptoms, including itching, discomfort, burning, pain during sexual intercourse, and whitish spots over the vulva. The most common histologic subtype is squamous cell carcinoma. The 5-year survival is 86 % for early clinical stages (CS) I-II, 53 % for locally advanced CS III-IVA, and 19 % for metastatic disease CS IVB. The classic treatment for high-grade VIN is surgical excision and, in the case of multifocal lesions, vulvectomy. Treatment is predominantly surgical in the early stages.

Background: In addition to mechanical methods, mouthwash, toothpaste, and fluoride gels are high-performance methods that can play an important role in reducing plaque and preventing caries in children. The purpose of this study was to determine the availability and use of oral health products related to children, and the familiarity of parents with methods to prevent decay. Methods: In this cross-sectional study, a checklist containing questions about the familiarity of parents with and the use of products related to children’s oral health was prepared and then completed by 325 parents of children aged 6 to 9 years who referred to the pediatric department dental clinics of the School of Dentistry. A dental student obtained information about the availability of products from pharmacies using a checklist. Data were analyzed with descriptive statistics and linear regression tests using SPSS 26 software. Results: This study showed that parents were relatively familiar with some health products such as dental floss and children’s toothpaste and mouthwash, but the information of parents was not enough on products such as casein phosphate, xylitol, and fluoride gel. About 40% of the pharmacies did not have finger toothbrushes or children’s toothbrush brands. One third of pharmacies did not have children’s mouthwash. No pharmacy had fluoride gel. Conclusion: This study showed that parents’ familiarity with children’s oral health products was low. Action should be taken to increase the awareness of parents. The reason for the lack of products in pharmacies should also be investigated and the existing obstacles to access them should be alleviated.

Modeling of CO Oxidation by Diffusion of Oxygen Atoms in Ceria-Zirconia Particulates in a Three-Way Catalyst Particle Membrane Filter
Authors: Koko Phyozin , Hanamura Katsunori
Published: November 2023

In order to design a microporous membrane filter comprising Three-way Catalyst (TWC) particles with a size distribution of 1 to 2 microns, isothermal CO oxidation experiments and numerical simulations were conducted to investigate the transport of oxygen atoms within primary Ceria-Zirconia (CZ) particulates. These spherical TWC particles were fabricated through the agglomeration of primary CZ and alumina particulates, incorporating Pd and Rh catalysts. By comparing experimental CO2 emissions with simulation results over time, a temperature-dependent diffusion coefficient was determined. The simulation results reveal that the effective distance of oxygen atom transport within CZ particulates, heterogeneously distributed in the spherical TWC particle, is limited to approximately 100 nm from the surface of agglomerated spherical TWC particles within a temperature range of 175 to 225°C.

Published: November 2023

Indonesia is one of the largest palm oil productions in the world. In 2017, Indonesia was responsible for almost 50% of global palm oil production. The abundant availability of Oil Palm Empty Fruit Bunches (OPEFB) has become a potential resource to be further utilized in derivative products such as cellulose, hemicellulose and lignin. The demand for nanocellulose material from extracted cellulose fibers is increasing. In this study, nanocellulose synthesis was carried out in several stages namely hydrolysis (H2SO4 64% (v/v) at 45oC for 45 minutes), delignification (NaOH 17,5% (w/v) at 80oC for 30 minutes), and bleaching (H2O2 10% (v/v) at 60oC for 15 minutes). Then, nanocellulose was subjected to ultrasonication. It was proved that nanocellulose with 50.487 nm diameters resulted from ultrasonication 50% amplitude. Moreover, adding 5%-w PVA (polyvinyl alcohol) as capping agent obtained 36.635 nm average diameter of nanocellulose. It showed nanocellulose synthesis successfully lowering agglomeration and maintaining diameter size of nano size.

Most of Indonesia's territory is geographically located in the coastal area. One of the areas located in the coastal area is the city of Meulaboh, West Aceh Regency. The coastal area of Meulaboh often experiences tidal flooding, especially the coastal area of Gampong Pasir and has a quite severe impact compared to other areas on the coast of Meulaboh. Based on this background, this study aims to identify community adaptation to the tidal flood event based on community responses in the coastal area and identify efforts to mitigate the impact of tidal floods that have been carried out by the community and the government. The analytical methods used are descriptive quantitative and qualitative analysis methods, as well as cross-tabulation analysis related to community adaptation variables, which include community characteristics, the impact of tidal floods on the residential environment, identification of tidal flood conditions and efforts to mitigate the impact of tidal floods, carried out by the community and the government. The results showed that the people of the coastal area of Meulaboh were able to make efforts to deal with tidal floods in the form of repairing road networks, residential houses, drainage channels, places of worship (mosques), village offices, and clean water and sanitation systems. The government's efforts to deal with tidal floods are carried out by making barriers to protect the coast through tetrapod. These results are important to take future action to deal with tidal floods.

Published: November 2023

Literasi merupakan salah satu program yang tengah marak disosialisasikan oleh pemerintah sebagai upaya untuk menumbuhkan minat masyarakat tentang budaya membaca akhir-akhir ini. Salah satu penyebabnya adalah beberapa hasil penelitian memperlihatkan betapa semakin menurunnya minat masyarakat terhadap kebiasaan membaca. Jangankan di wilayah perkotaan, di wilayah pedasaan bahkan lebih mengkhawatirkan selain karena kurangnya sarana/ruang untuk membaca, akan tetapi semangat untuk membaca juga sangat kurang. Kabupaten Takalar sebenarnya gerakan literasi sudah mulai menggeliat di beberapa wilayah di Kabupaten Takalar, misalkan di Kota Takalar dan sekitarnya, perpustakaan desa maupun perpusatakaan daerah mulai bertamba,. sedangkan Kecamatan Polongbangkeng Utara masih kurang terjamah. Salah satu kelurahan yang termasuk di dalamnya adalah Kelurahan Palleko. Berdasarkan hasil observasi, sebenarnya telah ada sosialisasi dari pegiat literasi di kelurahan ini berkaitan dengan program literasi desa, dan pada dasarnya antusias dari aparat kelurahan cukup besar terhadap program ini.  akan tetapi perlu ada sumber daya yang membantu kelurahan ini untuk mewujudkan program literasi tersebut.  Adanya program literasi pembuatan Sudut Baca Tubarani dari Tim pengabdian dosen Universitas Muhammadiyah Makassar berkolaborasi dengan mahasiswa Kuliah Kerja Nyata Muhammadiyah Aisyiyah (KKN-MAs), diharapkan dapat menjadi penggerak awal terwujudnya program literasi di kelurahan ini. Para pemuda yang bergabung dalam kelompok karang taruna di ajak berkolaborasi dan diberdayakan untuk membantu mahasiswa KKN-Mas mewujudkan program yang berbasis literasi. Olehnya itu program mahasiswa KKN-Mas kali ini bertujuan selain membantu pemerintah Kelurahan Palleko mewujudkan program literasi melalui pemberdayaan pemuda karang taruna, tetapi juga bertujuan untuk mengembalikan kesadaran membaca pada masyarakat yang semakin lama semakin menurun.

Korselt Numbers Through Computational Algorithms
Authors: Adarbeh Khalid , Hamad Hadi , Eshtaya Abeer
Published: November 2023

The Korselt numbers and sets were discussed for the first time in 2007. The problem can be considered as a new one with limited literature making it as a new field of research. Let N be a positive integer and α
a non-zero integer. If N ≠ α and p divides N for each prime divisor p of N, then N is called an α−Korselt number (Kα-number). In this thesis, many concepts such as Korselt numbers that are related to Carmichael numbers have been studied. Korselt determined Korselt numbers by studying the converse of Fermat’s Little theorem and it can be noticed that all these numbers depend on number theory, prime numbers, divisibility and modular arithmetic. To validate the concerned theorems, an illustrated proofs were followed through detailed steps in addition to many examples are solved in order to support the correctness of these theories. It is important to say that some errors in literature were addressed by us. Consequently, we introduced proper corrections for them. Finally, many notes have been taken and directed us to build and develop a number of complicated algorithms, some of them in order to find Korselt sets for relatively large numbers in an effective way in a short time which may require a great time and need tedious effort if it is to be calculated manually
Insights into the above- and belowground CO2 fluxes on pristine and managed peatlands: tools for examining ecosystem carbon cycle
Authors:   , Linkosalmi Maiju
Published: November 2023

Climate change and land-use changes modify the conditions and characteristics of northern peatlands and thus affect their carbon (C) balance. In this thesis the above- and belowground carbon dioxide (CO2) fluxes of peatland ecosystems were examined with process-specific methods. These methods provide additional information and support the standardized measurements. Phenology cameras were used for observing the seasonal development and greenness of vegetation at different ecosystems (pristine peatlands and a forest site). This vegetation phenology data was combined with CO2 flux measurements, meteorological data and satellitederived data. Also, the soil CO2 fluxes and priming effect (PE), i.e., the change in decomposition of soil after addition of fresh C, were studied in laboratory experiments with isotope techniques. The peat for these experiments was collected from two forestrydrained peatlands with different nutrient status. The phenology cameras were found to be a solid method for tracking changes in ecosystem greenness. Variations in vegetation dynamics were observed between different study years as well as between different ecosystems and plant communities within a peatland. These differences in vegetation greenness were linked to nutrient availability and vegetation composition of the site or the region of interest. The peatland vegetation also compensated for the late growing season start: during a summer with the latest growing season start the vegetation was capable to reach the maximum GCC and maximal photosynthetic activity over the measurement years. The effect of drought on greenness and maximal photosynthetic activity was found to depend on the hydrological features of the site. The camera- and satellite-derived greenness index showed similar seasonal cycle, but the poorer temporal resolution of the satellite data affected the reliable determination of the timing of different phenological phases. The results of the laboratory studies indicated that the nutrient-rich peat had higher basal peat respiration rate and also higher peat respiration in the presence of plants. The results are in accordance with the observed differences in the CO2 balances at the sites from which the peat samples were collected: the nutrient-rich peat soil has been observed to lose C and the nutrient-poor peat accumulate C. No priming or negative priming was found in these studies. Thus, it can be concluded that the addition of fresh C (in the form of seedling roots or glucose) did not increase, or it even decreased, the old peat decomposition in these peat soils. The negative priming was stronger in the peat soil with less nutrients available.

Authors: Machtakova A.I.
Published: November 2023

In a finite-dimensional Euclidean space, the problem of pursuit of one evader by a group of pursuers is considered, described by a system of the form
$$
D^{(\alpha)}x_i = a_i x_i + u_i, \ u_i \in U_i,\quad D^{(\alpha)}y = ay + v, \ v \in V,
$$
where $D^{(\alpha)}f$ is the Caputo derivative of order $\alpha \in (1, 2)$ of the function $f$. Sets of admissible controls~$U_i$, $V$ are convex compacts, $a_i$, $a$ are real numbers. Terminal sets are convex compacts. Sufficient conditions for the solvability of the problems of pursuit and evasion are obtained. In the study, the method of resolving functions is used as the basic one.

Authors: Hamdaoui Youssef , Abid Idriss , Michler Sondre , Ziouche Katir , Medjdoub Farid
Published: November 2023

High-quality pseudo-vertical p–n diodes using a GaN-on-silicon heterostructure are reported. An optimized fabrication process including a beveled deep mesa as edge termination and reduced ohmic contact resistances enabled high on-state current density and low on-resistance. A uniform breakdown voltage was observed at 830 V. The positive temperature dependence of the breakdown voltage clearly indicates the avalanche capability, reflecting both the high material and processing quality of the vertical p–n diodes. The Baliga figure of merit, around 2 GW cm−2, which is favorably comparable to the state-of-the-art, combined with avalanche capability paves the way for fully vertical GaN-on-Silicon power devices.

Authors: Fatikah Anun , Dian Budi Santoso
Published: November 2023

The preparation of primary care clinic accreditation in Indonesia still uses a manual system, causing unpreparedness and slowing down the performance of officers in preparing for accreditation. Other inhibiting factors are workload and adjustments to the latest accreditation standards. Accreditation is an important point in maintaining the quality of health care facilities. The fact that clinic accreditation in Indonesia is still quite low, only 1.7% of private clinics have been accredited out of 10,380. Driven by technological developments, it is necessary to develop a system that helps facilitate the documentation management and self-assessment. The research aims to design a system from problem analysis, system architecture to functionality. This research method using design thinking involves potential users at the Permata Keluarga Clinic and the design refers to the Clinic accreditation standards by the Ministry of Indonesian through H.K.01.07/MENKES/1983/2022. SIMAKLIK can be used by leaders and quality team members, accreditation assistance officers and surveyors. Features of this system prototype include: systematic documentation in accordance with the accreditation standard, self-assessment report features, dashboard, notes and recommendations features. This prototype has been successfully tested to users with SUS Score results of 81.78. The SUS Score results are categorized as grade B or very good, which indicates that the system's acceptability and usability are good.  SIMAKLIK has contributed to the development of a document management system as an innovative product in health care facilities, especially clinics. In the future, that prototype can be followed up through development by the engineer team.

Perilaku petani padi terhadap risiko usahatani pada suku yang berbeda di Jawa Timur
Authors: Murtadlo Kholid
Published: November 2023

Introduction: The agricultural sector is a sector that depends on natural conditions so that uncertainty and risk in farming always occurs. The source of risk is predicted to continue to grow which greatly affects the total agricultural yield. Farming risk consists of production risk and price. Production risk is related to production uncertainty. Price risk is related to price fluctuations that cause losses to farmers because prices are difficult to predict. Indonesia is known for its diversity with nearly 300 ethnicities. Each ethnic group has different characteristics in behavior, language and customs. This difference is possible to influence decisions in managing a business, including in dealing with farming risks. This study attempts to analyze the behavior of rice farmers on the risk of farming among various ethnic groups in East Java and factors that influence farmer behavior towards farming risk. Methods: This research was conducted in Pamekasan, Ngawi and Pasuruan, where these three districts represent Javanese, Madurese, and Madura-Javanese ethnic assimilation. The data used are primary data collected from 49 respondents in Pamekasan Regency, 72 in Ngawi Regency and 65 in Pasuruan Regency so that a total of 186 respondents using the cluster sampling approach. Farmers' behavior towards farm risk was analyzed using the Just and Pope risk function model with the utility function approach, while the analysis of factors that influenced behavior towards farm risk was carried out using multiple regression. Results: The results of the analysis show that the behavior of rice farmers in Pamekasan District with Madura ethnic risk seekers, in Pasuruan Regency is a risk averse and in Ngawi Regency is a risk seeker. Conclusion: Regression analysis shows that differences in ethnicity of farmers affect the way rice farmers deal with farming risks

Authors: Sumarokov O. M. , Nazarenko V. Yu.
Published: November 2023

Mountain flightless weevil Graptus weberi was previously known from literature data from seven regions of western Ukraine. Only three of them (Zakarpattia, Lviv, Chernivtsi) were convincingly documented, as specific localities were indicated for them. The finding of this species in Ivano-Frankivsk Region confirms the available data on its distribution in the Carpathian mountain range. The information on the distribution of G. weberi east of the Carpathians up to and including Vinnytsia Region needs to be confirmed

Authors: Verma Mukta
Published: November 2023

Introduction: To express the versatility of reverse sural artery fasciocutaneous ap used for coverage of
difcult wounds in the lower third of the leg and the foot. Material and Methods: From January 2017 to
April 2022, total 45 pedicled reverse sural artery aps were performed; out of them 22 aps were exclusively done for foot
reconstructions. All patients were males having varying degrees of skin and soft tissue loss with exposed bone [ tibia,
calcaneum, metatarsals]. Age group ranged from 7 to 65 years. Perforators were based on the sural artery. Results: The ap size
ranged from 15x8 cm [120 cm2] to 25x10 cm[250cm2]. Successful coverage with good functional and aesthetic appearance was
achieved in all patients. Donor sites were closed with split thickness skin graft in all cases. Reverse sural artery Conclusionfasciocutaneous ap can be considered as a workhorse ap for the reconstruction of moderate to large soft- tissue defects of the
lower leg and foot. It is relatively easy to execute, with no special needs for microsurgical instruments and with a low rate of
complications and good post-operative results.
Automated Measures of Sentiment via Transformer- and Lexicon-Based Sentiment Analysis (TLSA)
Authors: Zhao Xinyan , Wong Chau-Wai
Published: November 2023

The last decade witnessed the proliferation of automated content analysis in communication research. However, existing computational tools have been taken up unevenly, with powerful deep learning algorithms such as transformers rarely applied as compared to lexicon-based dictionaries. To enable social scientists to adopt modern computational methods for valid and reliable sentiment analysis of English text, we propose an open and free web service named transformer- and lexicon-based sentiment analysis (TLSA). TLSA integrates diverse tools and offers validation metrics, empowering users with limited computational knowledge and resources to reap the benefit of state-of-the-art computational methods. Two cases demonstrate the functionality and usability of TLSA. The performance of different tools varied to a large extent based on the dataset, supporting the importance of validating various sentiment tools in a specific context.
Deep Reinforcement Learning for Alleviation of Unbalanced Active Powers Using Distributed Batteries in LV Residential Distribution System
Authors: Pinthurat Watcharakorn , Hredzak Branislav
Published: November 2023

The high penetration and uneven distribution of single-phase rooftop PVs and load demands in power systems may lead to unbalanced active powers, adversely impacting power quality and system reliability. This paper introduces a strategy based on multi-agent deep reinforcement learning to address these unbalanced active powers. The approach involves deploying single-phase battery systems throughout the LV residential distribution system, subsidized by the utility. Initially, the unbalanced active powers are framed as a Markov game, which is then addressed using a multi-agent deep deterministic policy gradient algorithm. The strategy relies on local measurements, with agents' experiences centrally shared during training for cooperative tasks. Notably, information about the phase connections of the battery systems becomes unnecessary. The strategy learns from historical data, gradually mastering the process. Real data from rooftop PVs and demands in a four-wire LV residential distribution system validate the effectiveness of the proposed approach. Acting as adaptive agents, the battery systems collaboratively operate by adjusting active powers to minimize neutral current at the point of common connection.
Framing Cognitive Machines: A Sociotechnical Taxonomy
Authors: Albuquerque Pedro H. , Albuquerque Sophie
Published: November 2023

Aims: we propose a sociotechnical taxonomy for the analysis of socio-economic disruptions caused by technological innovations. Methodology: a transdisciplinary principled approach is used to build the taxonomy through categorization and characterization of technologies using concepts and definitions originating from cybernetics, occupational science, and economics. The sociotechnical taxonomy is then used, with the help of logical propositions, to connect the characteristics of different categories of technologies to their socio-economic effects, for example their externalities. Results: we offer concrete illustrations of concepts and uses, and an Industry 5.0 case study as an application of the taxonomy. We suggest that the taxonomy can inform the analysis of opportunities and risks related to technological disruptions, specially of those that result from the rise of cognitive machines.

Influence of inflammatory factors (IL-6, CRP, NLPR, D-Dimer, LDH) on the PaO2/FiO2 ratio, in patients with severe and critical degrees of COVID-19
Authors: Harnoto Yulia Octaviany , Assagaf Ali , Pratiwi Dewi Indah Noviana , Isa Mohamad , Nurrasyidah Ira , Kusumawardhani Erna
Published: November 2023

BACKGROUND: Several types of inflammatory biomarkers that are important in severe and critical Covid-19 infections include: levels of IL-6, C-reactive protein (CRP), lactate dehydrogenase (LDH), D-Dimer and neutrophil-lymphocyte platelet ratio (NLRP), which are independent variables. Meanwhile, the severity of Covid-19 infection can be determined by measuring the PaO2 /FiO2 ratio. However, the relationship between the PaO2/FiO2 ratio as the dependent variable is not yet known.
AIMS: To analyze the relationship between PaO2/FiO2 ratio and inflammatory biomarkers in COVID-19 patients
METHOD: An analytic observational study with a retrospective, cross-sectional approach. The research sample consisted of PCR-confirmed severe and critical COVID-19 patients who were treated in the isolation room of the Ulin Hospital in Banjarmasin from August–December 2021, who met the inclusion and exclusion criteria. Data analysis used the Spearman test to see the relationship between the PaO2/FiO2 ratio and various inflammatory markers.
RESULT: 52 severe and critical patients were observed according to the research flow. The number of male and female subjects (32/20) was found. The mean age was 55.38 years. The correlation test found that: there was no significant relationship between the PaO2/FiO2 ratio and IL-6 (p = 0.964), but there was a negative correlation between the PaO2/FiO2 ratio and: a).CRP (p = 0.038), b).LDH ( p<0.001), c).NLPR (p = 0.013), and d). D-dimer (p<0.001). The inflammatory biomarkers NLPR, LDH, and D-dimer are important independent variables for the severity of COVID-19, namely the PaO2/FiO2 ratio.
CONCLUSION: There are a significant correlation between the PaO2/FiO2 ratio to measure the severity of Covid-19 and several inflammatory biomarkers CRP, LDH, NLPR and D-dimer
Lucio’s Phenomenon in Lepromatous Leprosy Patient: A Rare Case Report
Authors: Amalia Irma , Widayati Agnes Sri , Ametati Holy , Rahmat Sugianto Yosep Ferdinand , Windayati Sri
Published: November 2023

BACKGROUND: Lucio’s phenomenon is a rare leprosy reaction, characterized by severe necrotic cutaneous lesions that generally occur in patients with untreated or inadequately treated lepromatous leprosy (LL).
OBJECTIVE: to describe and comprehend the diagnosis and management of Lucio’s phenomenon in leprosy patients
CASE: Male, 34 years old with extensive wounds on both arms and legs. About 3 years earlier, the patient felt burning heat in both hands and feet followed by loss of eyebrows and eyelashes, and a change in the shape of the nose. The patient had not received previous therapy. Physical examination showed that the patient appeared anaemic, leonine facies, megalobuli, madarosis, saddle nose, thickening of the ulnar and posterior tibial nerves, deformities of the fingers and toes, and amputations of several fingers. The dermatological status showed multiple ulcers of irregular shape and varying sizes with pus and necrotic tissue. Reitz serum test revealed a bacterial index of +3 with a morphological index of 90%, and routine blood showed hypochromic microcytic anaemia and leucocytosis. The patient received corticosteroid therapy, anti-leprosy combination therapy, antibiotics, iron tablets and wound care.
DISCUSSION: Lucio’s phenomenon consists of skin lesions that range from painful red-black patches to flaky blisters and ulcerations. These lesions usually occur on the lower extremities, and may extend proximally and distally. The lesions improved after administration of corticosteroids and anti-leprosy. Delayed diagnosis leads to significant disability and community transmission of the disease. The later the diagnosis, the more serious the disease becomes and can lead to death due to sepsis. Early diagnosis and appropriate treatment are important.
CONCLUSION: Early detection is crucial in order to deliver therapy earlier and prevent disease worsening.
