OBJECTIVES: As few mpox cases have been reported in Korea, we aimed to identify the characteristics of mpox infection by describing our epidemiologic investigation of a woman patient (index patient, the third case in Korea) and a physician who was infected by a needlestick injury (the fourth case).METHODS: We conducted contact tracing and exposure risk evaluation through interviews with these 2 patients and their physicians and contacts, as well as field investigations at each facility visited by the patients during their symptomatic periods. We then classified contacts into 3 levels according to their exposure risk and managed them to minimize further transmission by recommending quarantine and vaccination for post-exposure prophylaxis and monitoring their symptoms.RESULTS: The index patient had sexual contact with a man foreigner during a trip to Dubai, which was considered the probable route of transmission. In total, 27 healthcare-associated contacts across 7 healthcare facilities and 9 community contacts were identified. These contacts were classified into high (7 contacts), medium (9 contacts), and low (20 contacts) exposure risk groups. One high-risk contact was identified as a secondary patient: a physician who was injured while collecting specimens from the index patient.CONCLUSIONS: The index patient visited several medical facilities due to progressive symptoms prior to isolation. Although the 2022 mpox epidemic mainly affected young men, especially men who have sex with men, physicians should also consider mpox transmission in the general population for the timely detection of mpox-infected patients.
On the transference principle and Nesterenko's linear independence criterion
Authors: German Oleg Nikolaevich , Moshchevitin Nikolai Germanovich
Published: March 2023

We consider the problem of simultaneous approximation of real numbers $\theta_1,…,\theta_n$ by rationals and the dual problem of approximating zero by the values of the linear form $x_0+\theta_1x_1+…+\theta_nx_n$ at integer points. In this setting we analyse two transference inequalities obtained by Schmidt and Summerer. We present a rather simple geometric observation which proves their result. We also derive several previously unknown corollaries. In particular, we show that, together with German's inequalities for uniform exponents, Schmidt and Summerer's inequalities imply the inequalities by Bugeaud and Laurent and "one half" of the inequalities by Marnat and Moshchevitin. Moreover, we show that our main construction provides a rather simple proof of Nesterenko's linear independence
criterion.

Неравенства типа Харди для одной весовой функции и их применения
Authors: Nasibullin Ramil' Gaisaevich
Published: March 2023

Доказаны новые одномерные неравенства типа Харди для весовой функции вида $x^\alpha(2-x)^\beta$ при положительных и отрицательных значениях параметров $\alpha$ и $\beta$. В некоторых случаях константы в полученных одномерных неравенствах являются точными. Одномерные неравенства с дополнительными слагаемыми используются при обосновании многомерных неравенств с весовыми функциями, зависящими от степеней расстояния в среднем или функции расстояния до границы области. Пространственные неравенства доказываются в произвольных областях, в областях регулярных в смысле Дэвиса, в областях, удовлетворяющих условию конуса, в областях, $\lambda$-близких к выпуклым, и выпуклых областях. Константа перед дополнительным слагаемым в пространственном неравенстве зависит от объема или диаметра области. Как следствие этих многомерных неравенств в различных классах областей установлены оценки для первого собственного значения лапласиана при граничных условиях Дирихле. Одномерные неравенства также применяются при получении новых классов однолистных мероморфных в односвязных областях функций. Ослаблены известные достаточные условия однолистности типа Нехари-Покорного.

Многомерные тайловые $\mathrm{B}$-сплайны
Authors: Zaitseva Tatyana Ivanovna
Published: March 2023

Тайловые $\mathrm{B}$-сплайны в $\mathbb R^d$ определяются как автосвертки характеристических функций тайлов - специальных самоподобных компактов, замощающих пространство $\mathbb R^d$ параллельными сдвигами. Эти функции не кусочно полиномиальны, однако, являясь прямым обобщением классических $\mathrm{B}$-сплайнов, наследуют множество их свойств, при этом имея ряд преимуществ. В частности, в работе найдены точные показатели гладкости тайловых сплайнов, которые в некоторых случаях превосходят гладкость классических. На их основе построены системы ортогональных всплесков и получены оценки на скорость их экспоненциального убывания. На примере алгоритмов детализации поверхности (subdivision schemes) показана эффективность тайловых $\mathrm{B}$-сплайнов в приложениях, достигаемая в силу большей гладкости, быстрой сходимости и меньшего количества коэффициентов масштабирующего уравнения.

The current study included 83 patients with Ca glandulae parotis (72 men and 11 women) whose blood group affiliation to the AB0 and Rhesus factor systems was monitored. A comparison was made with a control group of healthy individuals from the modern Bulgarian population. The distribution of the blood groups in the sample was different from that of the control group (p <0.001). There was a significant increase in the prevalence of persons with blood group B (p <0.001), and a significant decrease in groups 0 (p <0.001) and A (p <0.05). In group AB, a slight increase in frequency was detected. With respect to the Rhesus factor, there was an increase in the patients with positive Rhesus factor - by 9.23% to 93.94% (p<0.05). It can be assumed that, among other risk factors, belonging to group B and having a positive Rhesus factor are one of the reasons for the appearance and development of the disease.

Published: March 2023

In this paper, we show a case study of Ryzen processor energy efficiency using SPECjbb2015 as the workload. We analyze it in comparison to Phenom II, a CPU of previous generation from the same manufacturer AMD. In terms of maxi-mum transaction throughput, Ryzen performs 218% of Phenom. With the response time constraint, the relative performance of Ryzen is 288%. In the energy efficiency, Ryzen achieves 309% (at maximum throughput) and 389% (with response time constraints) of Phenom. Dynamic frequency scaling (DFS) is effective for reducing the power consumption of both processors, but the load levels at which DFS is most effective are quite different.

Published: March 2023

Immunoglobulin (Ig) is a type of globulin produced by B lymphocytes during pathogenic infection of vertebrates. It has immune functions and can realize specific recognition and neutralization of corresponding antigens. As IgM is reported first in fish, IgM is the first antibody produced during immune responses and plays a vital role in systemic and mucosal immune tissues. IgM molecules have two forms: membrane-bound IgM (mIgM) and secreted IgM (sIgM). The latter is produced by plasmacytes and secreted into body fluid, existing as immunological effect molecules. The former embeds into B cytomembrane and exists as an antigen receptor. It binds with assistant molecules to form cell receptor compounds. This study reviews research progress on the structures and production processes of IgM genes in different fish species and the distribution characteristics of IgM on B cells, mediated signal pathways, and functions. It aims to enrich basic theoretical knowledge of fish immunology and provide some scientific references for disease control in fishes.

Published: March 2023

The present study examined urban earning determinants in the district of Multan. For this purpose, primary cross-sectional data was collected from District Multan urban areas. Data was collected from district Multan through a structured questionnaire in which 385 respondents from urban areas were interviewed randomly. This study was analyzed through Elementary and Econometric analysis.  The strict MEF was calculated by busing variables like education, experience and experience square. It was found that education and experience have a positive effect on earning while experience square negatively affected earning. Extended Mincerian Earning Function was calculating by using taking variables like education, experience, experience square, age, age square, spouse participation, migration, employment, and marital status. Education, experience, age, spouse participation, marital status, and migration positively effect on earnings while experience square, age square, and employment sector negatively affect earnings. The pairwise correlation analysis indicated a moderate problem of collinearity. Overall variables like (education, experience, age, migration, and spouse participation) have a higher impact on earnings in urban areas. The study suggests that the emphasis should be on improvement of education by investing in human capital as a result the quality of education, skill development, and the spread of knowledge can be improved which in turn can increases household earnings.

Boiler feed water pumps: techniques for improvement in design and balance of the drum
Authors: Javed Kashif
Published: March 2023

Boiler Feed Water Pumps (BFWP) are considered a critical part of boilers in power plant operations. The performance of the pump in a system is estimated by one of these quantifiers in pump performance (power, efficiency, head, and flow). The design and balance of the drum in the boiler feed pump are critical for the smooth flow and optimum efficiency of the pump. The wearing tolerance limits of the drum are correlated with the type of pump and the characteristics of the system in which it is installed. A study was conducted to evaluate the drum design at Saudi Aramco Jazan Integrated Gasification Combined Cycle (IGCC) Power Block Project. The study provided a mechanism for improvement in the design issues associated with the internal clearance of balance drums related to the BFWPs. Furthermore, gradual design improvements were also implemented. Successful performance testing of Boiler Feed Water Pumps (BFWPs) fitted with upgraded balance drums was also performed. This study provides a better understanding of drum design and techniques to improve the balance of the drum.
Health implications of the built environment: lessons for an evidence-based design
Authors: Ullah Ubaid , Iftikhar Sehar , Shah Syed Mansoor Ali
Published: March 2023

The purpose of the built environment had always been focused on protection from external hostilities (wild creatures, worse climatic conditions, etc.) and internal comfort. Recent studies suggest another spectrum regarding the physical and psychological implications of the built environment. As a specialised and crossed-disciplinary research area, the results are less than often conveyed and incorporated in the planning design practice. This research aims to develop a comprehensive base about the implications of the built environment for incorporation in future planning and design. The evidence-based design approach was used based on the extraction and analysis of published research from JSTOR, Google Scholar, PubMed, and Scopus through single and combined keyword searches, like the evidence-based design; architecture and health; impacts of layouts; social capital; healing environment; stress reduction; social support; views of nature; daylighting; urban planning and health etc. The data was analysed for different levels of evidence, and only those studies having excellent, good, and fair levels of evidence were included. The results were broadly categorised into two levels: the macro-level (urban and regional planning) and the micro-level (architectural level). The results of this study may improve the existing and future planning and design.

Purpose: The purpose of this study was to establish the influence of communication participants on adoption of Contagious Bovine Pleuropneumonia (CBPP) Vaccine among Arid and Semi-Arid Lands (ASAL) pastoralists in Kenya.

Methodology: The study population was pastoralists in Narok South Sub-county. Sample size was 468 respondents inclusive of qualitative and quantitative samples where 440 responded to questionnaire, 24 in focus group discussions, and 4 in key informant interviews. Cross-sectional research design entailing collection of qualitative and quantitative data was used to assess association between variables. Multi stage, purposive, simple random, systematic and stratified sampling techniques were then employed to come up with respondents. Data derived from 468 respondents was analyzed using statistical Package for Social Scientists (SPSS) version 20.0 and presented using regression coefficients and ANOVA.

Findings: All respondents engaged in discussions with others before vaccinating cattle against CBPP. This is because as members of social groups, they interacted with each other through networks, a dominant mechanism for diffusion. Within parameters of experts, veterinary officers and agro-veterinary sales people were influential. In the community, family and neighbours were equally influential and among peers were elders and herders. These influencers were effective because of their attributes and social qualities; trustworthiness and credibility, accessibility, knowledgeability, government authority, advised on many issues, related easily with others and were friendly.

Unique contribution to theory, practice and policy: Some people have influence over others in CBPP vaccine adoption among ASAL pastoralists. Governments, veterinary researchers, and communication experts need to leverage on them to encourage diffuse of the vaccine. These influencers could also be trained on some basic aspects of disease reporting, control and eradication.

Transdermal drug delivery system (TDDS) established itself as an integral part of novel drug delivery systems. In a broad sense, the term transdermal delivery system includes all topically administered drug formulations intended to deliver the active ingredient into the general circulation. Transdermal drug delivery systems are polymeric formulations which when applied to skin deliver the drug at a predetermined rate across dermis to achieve systemic effects. A transdermal patch is medicated adhesive patch that is placed on the skin to deliver a specific dose of medication through the skin and into the bloodstream. Often, this promotes healing to an injured area of the body. An advantage of a transdermal drug delivery route over other types of medication delivery such as oral, topical, intravenous, intramuscular, etc. is that the patch provides a controlled release of the medication into the patient, usually through either a porous membrane covering a reservoir of medication or through body heat melting thin layers of medication embedded in the adhesive. The main disadvantage to transdermal delivery systems stems from the fact that the skin is a very effective barrier; as a result, only medications whose molecules are small enough to penetrate the skin can be delivered in this method.

Objective: To present single surgeonâ€™s ten yearsâ€™ experience of Single stage reconstructive surgery in 26 neonates born with anorectal malformations (ARMs) and review of literature.
Methodology: This is a retrospective study of 26 neonates admitted in NICU with diagnosis of ARMs between period of June 2011 to Oct 2021 and managed by single stage reconstructive surgery with an average follow up of three years. All these patients were full term. The diagnosis was confirmed on clinical examination supported by cross table lateral film in prone position after 24 hours and ultrasound evaluation of level of rectal pouch. Single stage reconstructive surgery was done under general anesthesia within 24 to 48 hours after birth. The outcome of single stage reconstruction of neonates with anorectal malformations is evaluated post operatively during an average regular follow up of 3 years.
Results: All the 26 neonates are treated by single stage reconstructive surgery between 24 to 48 hours after birth during the period from June 2011 to Oct 2021 who were admitted with anorectal malformations in NICU after excluding associated congenital anomalies. Â All the patients had excellent cosmetic and functional outcome without significant problem of wound infection. Only 3 female patients with recto-vestibular fistula had mild superficial wound infection and were managed conservatively.
Conclusion: Single stage reconstructive surgery to treat ARMs in neonates I effective, safe and feasible with good continence. It avoids morbidity and higher cost associated with three stage surgeries and colostomy. This fact may further be confirmed through multi-institutional experience in large number of patients.

Trafik kazalarının önlenmesinde ilk yapılması gereken işlem kazaların yoğunlaştığı noktaların belirlenmesidir. Bu amaçla 2010-2019 yılları arasında Eskişehir kent merkezinde meydana gelen trafik kazaları istatistiksel olarak benzer, yaklaşım olarak farklı iki yöntem kullanılarak analiz edilmiştir. Çalışmada önce klasik sıcak nokta analizi kullanılmış ve 15 sıcak nokta tespit edilmiştir. Daha sonra aynı veri seti konum-zaman küpü kullanılarak zamana bağlı sıcak nokta yöntemi ile analiz edilmiş, 50 aralıklı, 10 yeni, 7 ardışık, 4 sürekli, 1 azalan ve 1 yoğunlaşan olmak üzere toplam 73 sıcak nokta bulunmuştur. İki yöntemin sonuçları kıyaslandığında, zamana bağlı sıcak nokta analizi ile 1. bölgedeki sıcak nokta sayısının 6'dan 19'a, 2. bölgedeki sıcak nokta sayısının 2'den 20'ye, 3. bölgedeki sıcak nokta sayısının 3'den 12'ye, 4. bölgedeki sıcak nokta sayısının 3'den 11'e ve 5. bölgedeki sıcak nokta sayısının 1'den 11'e çıktığı görülmüştür. Klasik sıcak nokta analizine kıyasla zamana bağlı sıcak nokta analizi ile farklı konumlarda ve farklı desenlerde daha çok trafik kazası sıcak noktalarının tespit edilmesi, konumun ve zamanın bir arada kullanılmasının önemini ortaya koymaktadır. Çalışma sonucunda zamana bağlı sıcak nokta analizinin klasik sıcak nokta analizine göre daha detaylı sonuçlar verdiği gözlemlenmiştir.

Published: March 2023

Bu çalışmada, Erzurum ilinde Yukarı Karasu Havzası’nın kuzeydoğu bölümünün heyelan duyarlılık analizi gerçekleştirilmiştir. Arazi çalışmaları ile 334 adet heyelan tespit edilerek heyelan envanter haritası oluşturulmuştur. Mevcut heyelanların %80’i analizlerde kullanılırken, rastgele seçilen %20’si ise duyarlılık performansının değerlendirilmesinde kullanılmıştır. Çalışma alanı koşulları göz önünde bulundurularak jeolojik, topoğrafik ve çevresel ilişkin parametreler analizlerde değerlendirilmiştir. Çalışmada hem frekans oranı yöntemi (FO) hem de Bayes olasılık modeli (BO) kullanılarak 5 farklı duyarlılık sınıfından oluşacak şekilde heyelan duyarlılık haritaları üretilmiştir. Daha sonra haritalar mevcut heyelanlarla karşılaştırılarak performans analizi gerçekleştirilmiştir. Frekans oranı yöntemine göre çalışma alanının %55.02’si, mevcut heyelanların ise %89.1’i yüksek ve çok yüksek duyarlı alanlar olarak belirlenmiştir. Bayes olasılık modeli ile üretilen duyarlılık haritasında ise çalışma alanının %41.21’i, mevcut heyelanların ise %76.45’i yüksek ve çok yüksek duyarlı alanlarda tespit edilmiştir. Bu sonuç çalışmada her iki yöntemle elde edilen heyelan duyarlılık haritalarının mühendislik projelerinin tasarımı ve mekânsal planlama çalışmalarında kullanılabilir nitelikte olduğunu göstermektedir.
Flood Inundation Mapping with Supervised Classifiers: 2021 Gediz Plain Flood
Authors: ARSLAN Enis , KARTAL Serkan
Published: March 2023

Generation of flood inundation maps is beneficial in flood risk assessment and evaluation. Flood inundation mapping can be achieved by many remote sensing techniques like change detection (CD) with thresholding and machine learning-based (ML) methods. Optical and synthetic aperture radar (SAR) imagery are widely used, provided by different satellite systems. This study used Sentinel-1 SAR and Sentinel-2 MSI satellite data in Google Earth Engine (GEE) with supervised ML algorithms. Gediz Plain, Turkey was selected as the study area, which is an agricultural area covered mostly by croplands. A flood event that occurred on February 2, 2021, was examined and flood inundation map for the study area was composed. Support Vector Machines (SVM), Random Forest (RF) and K-Nearest Neighbor (KNN) ML algorithms were selected and models were trained with manually created labelled data in GEE. Also, CD was applied on after and before event SAR images in a traditional approach. RF classifier performs best in Sentinel-2 MSI imagery with 94% overall classification accuracy where KNN classifier gives 93.3% accuracy value for Sentinel-1 SAR dataset, indicating the robustness of SAR imagery for all-weather conditions.
Review on Pushover Analysis Procedures
Authors: M Sam Horrison  , Dr. Selvan V  , Mr. Satheesh Kumar K. R. P
Published: March 2023

Pushover analysis was the recommended method of seismic analysis before this generation. Even though Non-Linear Time History analysis is a recommended method of practice for the current generation due to its accuracy, Pushover analysis has the capability which gives much more flexibility and information on its final results. The well-known concept of ‘Performance criteria’, which is the specification of an acceptable level of damage to a building, can be found using this method. Using pushover analysis, it’s possible to study the parent factor, which is responsible for the behaviour of buildings during seismic events. In this review, we discussed the possible lateral load combinations that can be applied during the analysis procedure and how the results can be analysed. From previous studies, it is concluded that the pushover analysis can be influenced by the geometry of the building, lateral load pattern, and the method of result evaluation.
