Published: May 2023

Background:

Even though excess mortality in patients with severe mental disorders (SMD) has been established in many high-income countries, literature on this from the low- and middle-income countries including India is rather scant. Our study seeks to estimate the standardized mortality ratio (SMR) of patients with SMD from a rural community in Tamil Nadu for the years 2011–2015.

Materials and Methods:

We included patients with SMD from four taluks of Pudukkottai district, Tamil Nadu, during the years 2011–2015. We collected information on a total number of patients with SMD registered, their sociodemographic details, alive/dead status, and cause of death from the clinic registers and patient case records. We used the crude death rates for rural Tamil Nadu for the years 2011–2015 for the calculation of SMR, which is calculated by the formula observed deaths/expected deaths.

Results:

The SMR of patients with SMD was 3.33, 2.76, 2.11, 1.91, and 1.89 in the years 2011–2015. Of the 74 total deaths in these 5 years, 62 (83.7%) were due to natural causes, while 12.2% died by suicide. Statistically significant differences were observed in age, education, and marital status between patients with SMD who were alive and dead.

Conclusion:

We observed nearly two-times higher mortality among patients with SMD in rural Tamil Nadu. Further research is needed to examine the reasons for increased mortality among patients with SMD and interventions to reduce this excess mortality.

Comparative analysis of cyclin-dependent kinase 2 density by immunohistochemistry in lesional versus nonlesional psoriatic skin
Authors: Elmorsy Eman H. , Alsawy Eman S. Ali Gawdat , Elsronbawy Basma S.A. , Taha Alsayeda A.A.
Published: May 2023

Background

Psoriasis is a noninfectious, inflammatory, and hyperproliferative skin disorder. Cyclin-dependent kinase 2 (CDK2) is a serine-threonine protein kinase that plays a role in the transition of G1/S, the initiation of DNA synthesis, and the regulation of the S phase exit in the cell cycle. CDK2 is uniformly expressed in healthy human epidermis being located mainly in the cytoplasm and nuclei of basal keratinocytes.

Objective

To compare the CDK2 density by immunohistochemistry in lesional versus nonlesional psoriatic skin and normal control and to correlate its expression with disease severity.

Patients and methods

This study was conducted on 30 patients with plaque psoriasis and 20 age-matched and sex-matched controls. Biopsies were obtained from the active plaque (lesional) and nonlesional skin of the patients and normal controls. CDK2 density was assessed by counting immunohistochemically positive nuclei in 1000 suprabasal keratinocytes at ×400 power fields.

Results

CDK2 was negative in normal control skin (no positive nuclear staining was seen in suprabasal keratinocytes). Meanwhile, the psoriatic group showed diffuse nuclear positivity in suprabasal cells. The density was significantly higher in lesional versus nonlesional skin. CDK2 density in lesional and nonlesional skin showed a statistically significant correlation with Psoriasis Area and Severity Index score (r=0.820 and 0.683, P<0.001 and <0.001, respectively).

Conclusion

CDK2 density is high in plaque psoriatic epidermis more than in nonlesional and control skin, and this was positively correlated with disease severity. It indicates that it may play a role in the development of psoriasis and may be a potential therapeutic target.

Published: May 2023

AIMS AND OBJECTIVES:

To derive a new horizontal plane which can be a suitable alternative to Frankfurt horizontal plane (FH plane).

MATERIALS AND METHODS:

200 pre-treatment lateral roentogenic cephalograms from patient records in the department of orthodontics and dentofacial orthopaedics were traced. The landmarks were identified and marked and the measurements were carried out. Patients with all skeletal relationships were included in the study. The angle formed between the lines connecting anatomic porion, orbitale and machine porion was measured and tabulated. Dimorphism between the genders if any was also evaluated.

RESULTS:

The mean angulation between the planes from the anatomic porion to orbitale to machine porion (PoA-Or-PoM) in our sample is 3.14 ± 2.17°. PoA to Or to PoM angulation for males is 2.57° and for females is 3.4°.

CONCLUSIONS:

SIDS plane also called as derived FH plane given here is a reliable and easily reproducible alternative to the FH plane.
The Function of Forward Planned Intensity-modulated Radiotherapy Technique in Radiotherapy of the Intact Breast Dose Distribution Optimization
Authors: Rather Sajad Ahmad , Khan Aijaz Ahmad , Banday Muddasir Sharief , Tali Tavseef Ahmad , Baba Misba Hamid
Published: May 2023

ABSTRACT

Objective:

The recommended course of treatment for early-stage breast cancer is breast-conserving surgery followed by adjuvant whole-breast radiation. It is challenging to obtain homogeneous dose distribution using standard procedures because of breast irregularities. Currently, it is possible to use different breast irradiation techniques such as a field in field (FIF) which produces a more homogenous distribution of doses within the target volumes while sparing the organs at risk, leading to a better treatment outcome.

Materials and Methods:

The present study aimed to compare the conformal and the FIF techniques dosimetrically. In this retrospective dosimetric study, we evaluate 20 patients with early-stage breast cancer who underwent computed tomography. For each patient, two different treatment plans were created, three-dimensional conformal radiotherapy and a FIF plan. A dose of 50 Gy in 25 fractions was prescribed to the planning target volume (PTV).

Results:

The plans were compared with each other on volume coverage (conformity and homogeneity) and OAR sparing. The dosimetric parameters and monitor components were compared with paired sample t-test. The FIF technique obtained a significantly lower dose homogeneity index, lower maximum doses, and higher median doses in PTV (P < 0.05). In ipsilateral lungs, FIF significantly reduced the maximum and mean doses (P < 0.05). In patients with left-sided breast cancer, minimum and maximum doses and V40 of the heart were significantly decreased in FIF plans (P < 0.05). Doses to the contralateral lung differ to a little degree as well.

Conclusion:

The use of forward intensity-modulated radiation therapy (RT) technique for RT of high-risk node-positive breast cancer patients provides an efficient and reliable method for achieving superior dose uniformity, conformity, and homogeneity in the breast chest wall volume with minimal doses to the OAR. Monitor units were less in FIF, with less time on the machine and less machine consumption.
Minimal area of Finsler disks with minimizing geodesics
Authors: Cossarini Marcos , Sabourau Stéphane
Published: May 2023

We show that the Holmes–Thompson area of every Finsler disk of radius

r

whose interior geodesics are length-minimizing is at least

\frac{6}{\pi} r^2

. Furthermore, we construct examples showing that the inequality is sharp and observe that equality is attained by a non-rotationally-symmetric metric. This contrasts with Berger’s conjecture in the Riemannian case, which asserts that the round hemisphere is extremal. To prove our theorem we discretize the Finsler metric using random geodesics. As an auxiliary result, we include a proof of the integral geometry formulas of Blaschke and Santaló for Finsler manifolds with almost no trapped geodesics.
On curves in K-theory and TR

A Coupling Architecture for Remotely Validating Powertrain Assemblies
Authors: Ametller Adria , Brace Chris
Published: May 2023

Among the myriad of potential hybrid powertrain architectures, selecting the optimal for an application is a daunting task. Whenever available, computer models greatly assist in it. However, some aspects, such as pollutant emissions, are difficult to model, leaving no other option than to test. Validating plausible options before building the powertrain prototype has the potential of accelerating the vehicle development even more, doing so without shipping components around the world. This work concerns the design of a system to virtually couple—that is, avoiding physical contact—geographically distant test rigs in order to evaluate the components of a powertrain. In the past, methods have been attempted, either with or without assistance of mathematical models of the coupled components (observers). Existing methods are accurate only when the dynamics of the systems to couple are slow in relation to the communication delay. Also, existing methods seem to overlook the implications of operating a distributed system without a common time frame. In order to overcome the inherent latency arising from long-range communication, the proposed design combines two features: The exploitation of synchronized clocks for the simultaneous introduction of setpoint commands and the use of observers generated through machine learning algorithms. This novel design is subsequently tested in two scenarios: A simple one, involving the virtual coupling of two parts of an elementary device formed by three rotating inertias, and a more complex one, the coupling between an internal combustion engine and an electric motor/generator as representative of a series or parallel hybrid powertrain. Although the results are heavily influenced by the quality of the data-generated observers, the architecture improves the fidelity of the coupling by nearly an order of magnitude compared to the alternative of directly transmitting the signals. It also opens a niche application that leverages the accuracy of low-fidelity models.

Climate litigation in Latin America: is the region quietly leading a revolution?
Authors: Tigre Maria Antonia , Urzola Natalia , Goodman Alexandra
Published: May 2023

Climate litigation is a hot topic. Worldwide, jurisdictions are being presented with novel legal cases aiming to address the devastating effects of climate change. Domestic, regional and international courts are facing the challenge, deciding climate-related cases by using a myriad of approaches. Latin America is host to many of these climate litigation cases. Yet, in mainstream climate litigation literature, the role of litigation in Latin America is often overlooked, especially the role of litigation in ‘peripheral’ claims. We argue that limiting the definition of climate litigation to cases that directly invoke climate-change-related claims, albeit useful, ignores a significant number of cases with potentially strong influence in climate governance. We contend that Latin America provides a wide and relevant range of climate cases that could inform how climate governance is shaped, but that the majority of these cases rely on ‘peripheral’ climate claims: that is, on claims that may not directly mention climate change laws or data but which nevertheless have an impact on climate governance. Some of these claims refer to biodiversity protection (ie in the Amazon basin), while others appeal to climate change causes (ie air pollution). Furthermore, cases with innovative approaches such as those invoking the Rights of Nature or Intergenerational Equity also touch upon climate governance and the human–nature relationship. This article draws on the expanding body of climate-related cases in Latin America in order to assess the role of the region in advancing climate litigation.

Jüdische Geschichte in Deutschland vor 1933
Authors: Gohl Fabian , Stello Benjamin
Published: May 2023

Seit etwa 1700 Jahren ist deutsche Geschichte immer auch jüdische Geschichte. Diese Gegenseitigkeit auf Verfolgung und Shoa zu reduzieren, greift zu kurz. Jüdinnen und Juden erfuhren in Deutschland unterschiedliche Phasen: neben Verfolgung und Bedrohung gab es auch Perioden der Konsolidierung, des friedfertigen Miteinanders sowie der kulturellen, geistigen und ökonomischen Blüte. Dieses Heft nimmt alle diese Aspekte auf und macht sie anhand beispielhafter Stationen aus unterschiedlichen Epochen für den Geschichtsunterricht sichtbar. Das sofort einsetzbare Arbeitsmaterial kann entweder ergänzend zum regulären Geschichtsunterricht oder als separater Längsschnitt verwendet werden.

Published: May 2023

Nach dem Richtungsstreit der 1970er Jahre war die Hinwendung zu praktischen Fragen des politischen Unterrichts mit einem Verzicht auf Theoriebildung einhergegangen. Dennoch wurde der Pragmatismus immer wieder als „Metatheorie“ der politischen Bildung vermutet, aber als solche nie expliziert. Die Pragmatistische Politikdidaktik leistet diese Explikation und ermöglicht im Anschluss an die Kompetenzdebatte eine Grundlegung zentraler Bausteine des Faches zum Beispiel die Förderung politischer Urteilsbildung.
Produção do espaço urbano em Ituiutaba-MG: análise da expansão territorial e dinâmica demográfica no período 2010-2019

Published: May 2023

Vivenciamos um cenário de significativa defasagem em relação aos dados censitários disponibilizados pelo Instituto Brasileiro de Geografia e Estatística - IBGE, uma vez que o último Censo Demográfico foi realizado em 2010. O adiamento do levantamento, inicialmente previsto para 2020, levou ao desconhecimento de muitas transformações ocorridas ao longo dos anos, sobretudo considerando-se a produção habitacional expressiva por meio do Programa Minha Casa Minha Vida – PMCMV, iniciado em 2009. A cidade de Ituiutaba-MG enquadra-se nesta conjuntura, uma vez que recebeu quase cinco mil unidades habitacionais por meio da implantação de doze conjuntos habitacionais a partir de 2010. Tal contexto gerou impactos relevantes, já que a cidade possuía, em 2010, pouco mais de 93 mil habitantes. Sendo assim, procuramos levantar informações que pudessem contribuir para a análise destas transformações e, neste caso, encontramos na base de dados do Centro de Controle de Zoonoses do município uma solução alternativa. A partir destas informações, foram produzidos mapas e tabelas que compatibilizaram os recortes territoriais dos setores censitários e bairros. Os resultados contribuem para elucidar as expressivas transformações ocorridas no âmbito da produção do espaço urbano em Ituiutaba no período 2010-2019, principalmente no que se refere à expansão territorial e a distribuição populacional, mesmo diante da ausência de dados censitários atualizados.

Published: May 2023

The fingerprint recognition approach uses a variety of techniques, each of which is based on particular criteria. Finding an effective method for fingerprint recognition is the goal of this work. The goal of this project is to provide a straightforward, high-performance fingerprint recognition method. This strategy consists of two main phases: The first step is actually collecting data from samples of human fingerprints, and the second step focuses on designing and implementing a highperformance fingerprint recognition method. The feature extraction phase, in which numerous levels of the two-dimensional discrete cosine transform (D-DCT) are utilized to generate highperformance features, was the primary focus of the implemented strategy. By combining the functions of the right and left thumbs, this strategy is carried out. According to the findings, this method achieves a high level of recognition accuracy. Choosing the security architecture and policies for a system is a difficult task that must be guided by an understanding of user behavior in the proposed work to Improve data security against darker we. Shamir cryptography is the subject of our free fuzzy vault-based fingerprint cryptosystem that makes use of highly discriminative pairpolar (P-P) minutiae structures. Our system's use of fine quantization makes it possible to use a well-known, conventional minutiae matcher right away and retain a significant amount of information about a fingerprint template. The proposed fingerprint cryptosystem outperforms other minutiae-based fingerprint cryptosystems and is highly secure when compared to a few publicly available databases.

Асортимент та розподіл кластерів за величиною, тобто кластерна система решітки, визначає її властивості. Запропоновано спосіб діагностики складних електронних схем, що базується на такому поданні. Спосіб має дві складові. Перша призначена для практикного використання, не вимагає застосування математичного апарату перколяційної теорії, і зводиться до перетворення принципових електронних схем на паралельні та послідовні з'єднання однотипних елементів ланцюга. Це призводить до спонтанного створення кластерної системи елементів і дозволяє знайти елементи, які розташовані поблизу несправного, і, отже, мають знижений ресурс працездатності. Друга складова призначена для подальшого дослідження схем. Для цього необхідно використовувати перколяційний аналіз переформатованих схем. Такий аналіз дозволяє окрім геометричних параметрів дослідити електропровідність схем, отримати критичний індекс потужності, а також розрахувати фрактальну та хімічну розмірність скелета нескінченного кластера та його лакунарність. Мета подальших досліджень – виявлення залежностей перколяційного типу між структурою та властивостями схем електронних приладів.

One of the disorders of mental health that often occurs in individuals is depression. Identifying depression in the first place is important for the individual. But in fact, conducting an early examination of depression still has some drawbacks. If it continues to be ignored, this can have an impact on the health of the individual. Therefore, there is a need for other methods that can represent the level of depression in individuals, through other media such as social media such as Twitter. Twitter has become one of the media to tell what users of the application experience or feel. This is encouraging to detect of depression in Twitter users. The data used is data taken from the results of the distribution of forms based on DASS-42 with a total of 159 Twitter users for each username taken 100 tweets. This study uses the Word2Vec extraction feature, to convert data from text to vector by looking at the relationship of each word and Random Forest as a classification method, to maintain the balance of data in different classes, especially very large data sets. Based on the test results, the Random Forest model produces an accuracy of 68.75%.

Indonesia has great natural resources. UNESCO recognized at least six geoparks, and Indonesia will continue to develop more geoparks in the future. However, currently, Indonesia's geoparks are not widely known. One of the reasons is that the existing websites do not pay attention to performance guidelines, information, economics, and search engine optimization even though the website is a vital marketing medium so that geoparks can be promoted widely and effectively. A comprehensive study of the website contents is required to build a good geopark website. In addition, it is also necessary to study user experience when visiting web pages. This study aims to find the standard website content on the geopark website and compare existing website performance and user experience. This study compares three geopark websites. The three websites include the Ciletuh-Palabuhanratu, Hongkong geopark, and Cliff of Fundy Geosite website. Three indicators are used: website performance, user experience, and what information should be on the geopark website. These three indicators are essential as an attraction for website visitors so they can enjoy the content of the website and they can stay longer so that the visitors can turn into potential geopark tourists. Good website performance is supported by consistent ease of providing information and speed in providing information to website visitors. In comparison, the user experience visiting the website relates to the interactive visual design, organization, and navigation structure of the website framework and the completeness of the content. We use performance and user experience metrics as evaluation tools for the three selected websites. As a result, the general availability of information is as follows: information about geoparks, UNESCO, list of tourist attractions, activities, itinerary, tourist accommodation, education, contacts, language choices, news articles, pamphlets, maps, and virtual tours. In terms of performance, the three websites have slow speeds, but in cumulative layout shifts, they have good scores.

Indonesia is one of the countries whose buying and selling activities have shifted from traditional buying and selling activities to electronic ones. This is evidenced by the increasing prevalence of e-commerce applications which are directly proportional to the number of people who have downloaded them. With so many e-commerce applications out there, everyone has their own opinion when using the application. This can be seen in the number of user ratings on each e-commerce application, such as the Tokopedia application. The purpose of this study was to determine the effect of the quality management of the Tokopedia platform on customer satisfaction. The method used in this study is the PIECES Framework which includes 6 dimensions of performance, information, economics, control and security, efficiency, and service variables for the Tokopedia E-commerce Application.

Merdeka Belajar Kampus Merdeka (MBKM) program enables universities to convert independently the programs into department courses hence those can be considered as its course credits. MBKM program guideline requires universities, specifically departments, to carefully convert MBKM program since they have to consider Program Learning Outcomes (PLO) and relevancy of courses in the conversion process. To follow the guideline, departments must explore learning outcomes of each courses and learning outcome of the programs. The job is certainly time and resource consuming. Therefore it needs to be supported by a reliable strategy and system to manage efficiently and effectively relational data between MBKM program, PLO and courses. Through these data, departments then enable to identify quickly related courses with those programs. This paper introduces a model to represent the conversion strategy. We then developed in-house application called e-OBE to implement the model to enable the departments to map PLO, MBKM program and course data efficiently and effectively. The mapping data can be used to retrieve department courses quickly in which their PLO are linked with MBKM program PLO. Finally, a recommendation based on text similarity from courses and MBKM program can be generated automatically to support department decision in the conversion process.
