The Ordovician development of the Actinoceratida, with notes on Actinoceroid morphology and Ordovician stratigraphy
Authors: Flower Rousseau H.
Published: March 2023

Part 1: Descriptions of new Ordovician species of Actinoceratida are combined with a review of the evolution and faunal development of the order in the Ordovician. New morphological information includes spatial relationships of cameral and siphonal deposits in complete shells of several species, and a revised concept of the canal system. Occurrences of antinoceroids in the Ordovician of North America, eastern Asia, and northern Europe are summarized. A revised concept of evolution of the group is presented. Reason is given for regarding Bathmoceras as the ancestor of the order; it gave rise to Polydesmia having thick primitive rings and dendritic radial canals. Reticulate canals characterize Whiterock actinoceroids, of which the genera Wutinoceras, Cyrtonybyoceras, and Adamsoceras are characteristic. Ormoceras, developed from Adamsoceras, continues beyond the close of the Ordovician, giving rise to Deiroceras, of which Troedssonoceras is a synonym. Actinoceras yields itself to division into species groups of faunal and stratigraphic value. Leurorthoceras is a synonym of this genus, and Saffordoceras and Troostoceras are doubtfully distinct. Kochoceras is derived from Actinoceras. Internal differences indicate that Gonioceras and Lambeoceras are homeorphic but not closely related.

Stratigraphic notes include a general discussion of the Ordovician, with special reference to the recent revisions, recognition of a pre-Chazyan interval, the Chazy-Black River hiatus, and the correlation of the Red River beds with the Cobourg and Eden. A revision of the Montoya Group is presented. The importance of austral-boreal oscillations is emphasized, the actinoceroids being predominantly boreal in faunal affinities, although in Cobourg time Deiroceras and Orthonybyoceras invaded the austral realm. The systematic portion includes discussion of 15 genera, one of which, Adamsoceras, is new. Thirty-one species are described and illustrated, all but two of which are new; these are listed in the table of contents.

Part II: The new genus Macroloxoceras is described from two species; the genotype M. magnum, from the Dyer Dolomite of Colorado, and M. minor, from the Percha Shale of New Mexico, both very late Devonian age. Together with Bergoceras, Paraloxoceras, and Pseudactinoceras, this genus comprises the new subfamily Macroloxoceratinae of the Pseudorthoceratidae. Although in the entire subfamily there is a strong resemblance to Rayonnoceras, reexaminations of the evidence suggests this relationship is homeomorphic, though a remarkable example of contemporaneous convergence. Pseudocyrtoceras, sp. Schindewolf is assigned to the Pseudorthoceratinae. In spite of its resemblance to the Macroloxoceratinae, Rayonnoceras retains actinoceroid features favoring its derivation from Ormoceras.
Part I. Montoya and related colonial corals. Part II. Organisms attached to Montoya corals
Authors: Flower Rousseau H.
Published: March 2023

Twenty-seven species are described from the Montoya Group of New Mexico; 17 from the Second Value Formation; 6 from the Aleman, and 5 from the Cutter; 1 species being common to the Aleman and the Cutter. Only four species have been described previously; the others are new. Four species are not determined specifically. One Aleman species is tentatively identified in the Cutter; others are distinct for the three formations. Two new genera, Crenulites and Trabeculites, are described. Species from other regions described and discussed, and in some cases revised, include five species of Favistina, Protrochiscolithus magnus, and Saffordophyllumcrenulatum, three of Crenulites, one of Trabeculites, and two assigned to Foerstephyllum.

Regional analysis strengthens the Red River affinities of the Second Value Formation and the Richmond equivalence of the Aleman and Cutter Formations, but fuller evaluation must await more precise study of corals of other Ordovician faunas, particularly in western and northern North America.

Revised concepts of morphology and relationship are required, notably the derivation of septa as secondary structures from a primitive wall, and the primitive nature of a simple fibrous wall from which are derived trabecular walls on the one hand, and walls with an axial plate on the other, the axial plate developing both into the primary wall of the higher Favositidae, and into the epitheca of the rugosan types. The present study fails completely to support division of these corals into Tabulata and Rugosa, but it is felt that alternate proposals would be premature. A new structure, poikiloplasm, is described, which may line carallites, be concentrated as spherical knobs, with or without a thin connection, or form groups of discrete spheres.

A summary is appended, briefly summarizing characters by which the Montoya species can be differentiated readily.

A Study on Preceding Studies and Existing Bibliography on Records of Gisaeng and Changgi and the Colored Copy of 2022
Authors:   Korean Society of Gyobang and Culture, Lee Jeongnam , Mizutani Sayaka
Published: March 2023

This study explored “Preceding Studies” and “Existing Bibliography” that utilized the Records of Gisaeng and Changgi as well as “Recent Research Trends” that verified and corrected the academic errors and distortions found in those studies and bibliography to derive the state and problems of the existing copies of the Records of Gisaeng and Changgi. After figuring out the problems found in the existing copies, this study emphasized the need for new copy and described the process of obtaining the new copy (the colored copy of the Records of Gisaeng and Prostitute on June 30 2022) based on academic proposal and request to the National Archives of Korea. Then, this study came up with the value and utilization direction of the new colored copy.
To establish the correct understanding on “Fundamental Characteristic and Truth of Records of Gisaeng and Changgi,” it is necessary to publish the new 2022 copy for Records of Gisaeng and Changgi and books that compile reprinted copy, accurately translated copy, and the recent studies on Records of Gisaeng and Changgi. These new copy and books will correct academic errors and distortions discovered in previous studies and existing bibliographies based on Records of Gisaeng and Changgi, as well as widely spread the corrections as well as newly discovered facts.
Records of Gisaeng and Changgi should be easily accessible to both researchers and ordinary people in order to highlight the value and fundamental characteristics of Gisaeng and prostitute, as well as to promote the correct understanding and new perception toward the Korean modern history of Gisaeng and prostitute by clearly distinguishing and understanding the concepts of “Gisaeng Group” as the artist group that inherited the tradition of female musicians and “Prostitute Group” as the prostitute group who lived on prostitution during The Korean Empire’s turning point of modernization.
Lastly, Although the Gisaeng during the Joseon Dynasty, the Daehan Empire, and the Japanese colonial era was not free from the sexual amusement and exploitation of the men under the Confucian society and the Japanese colonial rule, Gisaeng was not a prostitute who made a living by the prostitution. Gisaeng was an entertainer who learned music and dance every day at Jangakwon in the Joseon Dynasty, Goybangsa in the Daehan Empire, and Gisaeng Association and Gwonbeon in the Japanese colonial period. Gisaeng also made a living by doing music and dance at the royal court events, public events, private events, theaters, and restaurants.
Joseon culture exhibited in Japan in 1922: focusing on the photo album of Peace Memorial Tokyo Expo
Authors:   Korean Society of Gyobang and Culture, Lee Bu Yong
Published: March 2023

This paper explores Joseon culture displayed in Ueno, Tokyo in 1922, focusing on the photo album of the Peace Memorial Tokyo Expo. First, the overall composition of the photo album was analyzed. The intention of the issue, the purpose of the event, and the direction of the exhibition were researched, and the colonial times were examined focusing on the characters presented in the picture at the beginning. Next, the Joseon culture exhibited at the fair was analyzed. Despite the fact that the artistry of the Gisaengs in the entertainment hall became a hot topic, the selection of songs and performances consisted of simple contents that had a common cultural basis or did not encourage conflict between the two countries. In contrast to Japan’s emphasis on modern industrial technology, the exhibition of the Joseon Pavilion was poor and stressed on the agriculture. In conclusion, by the analysis of the photo album and its surrounding materials, it can be seen that Japan tried to display Joseon culture in a biased way and further solidify its colonial rule, unlike the slogan “Peace” that was put forward through.

Pemindahan Ibu Kota Negara (IKN) Indonesia dari Jakarta ke Kalimantan Timur tepatnya ke daerah Sepaku, Penajam Paser Utara yang digagas Presiden Jokowi dan disahkan DPR RI melalui rapat paripurna pada 18 Januari 2022 diyakini memberikan dampak ekonomi, sosial dan budaya yang signifikan. Dampak yang dimaksud tidak hanya bagi kawasan yang menjadi lokasi IKN, tetapi juga untuk kawasan yang ada di sekitarnya, termasuk Kabupaten Tabalong yang berjarak kurang lebih 203 km dari kawasan IKN. Sebagai salah satu gerbang utama dari IKN baru, penting untuk mengkaji kesiapan masyarakat adat Dayak Deah dalam menyambut IKN. Penelitian dilakukan pada 06 Mei 2022 dengan menggunakan penelitian kualitatif melalui wawancara dan focus group discussion di Desa Kinarum. Hasil penelitian menunjukkan bahwa masyarakat Dayak Deah bangga, senang, siap dan memiliki rencana kongkret. Walaupun sadar bahwa pemindahan IKN sebagai peluang sekaligus tantangan. Bagi mereka penting adanya relasi timbal balik antar pemerintah dan masyarakat, sehingga ada komitmen untuk melakukan pemberdayaan masyarakat melewati pemerintah desa, penguatan kapasitas lembaga adat, dan pengembangan Kampung Budaya. Pada akhirnya bagi mereka “Mau tidak mau, harus siap; Siap tidak siap, harus dihadapi”. Semangat gotong royong dan solidaritas bersama menjadi kekuatan dalam menghadapinya.
Las urbanizaciones residenciales cerradas en la periferia de Córdoba Nuevas modalidades en la expansión suburbana del siglo XXI.
Authors: Romo Claudia
Published: March 2023

El proceso de cambio estructural producido en Argentina hacia los años noventa, con la puesta en marcha de políticas neoliberales, se traduce en nuevas reglas en los órdenes político, económico y social. Esta reestructuración introduce profundas transformaciones en los modos de producción del espacio suburbano de la ciudad de Córdoba. Una de ellas es la incorporación de nuevas ideologías respecto de alternativas diferenciadas en los modos de vida residencial. Las mismas encuentran sus antecedentes en países del norte y cobran significativa importancia en el espacio periférico de la ciudad a partir de los años noventa. Reconocidas como urbanizaciones cerradas o tipologías suburbanas de vivienda permanente, se localizan en la periferia, en un predio con vigilancia y acceso restringido y constituyen un producto creado y producido por el mercado inmobiliario. Este patrón residencial emergente, producido a ritmo acelerado en los últimos años y localizado especialmente en el sector metropolitano norte-noroeste de Córdoba, genera disfunciones en la periferia y deterioro en la calidad de entornos y paisajes del espacio de la ciudad. La materialización de las intervenciones sobre antiguas estructuras organizativas de la ciudad, sin mediar acciones intermedias en materia de soporte vial, de transporte, equipamiento e infraestructura, son algunas de las consecuencias negativas más destacadas. Entre las causas que pueden dar cuenta de la consolidación de este fenómeno, las más significativas se relacionan con la consolidación del modelo neoliberal en la realidad nacional, sus consecuentes cambios operados en la modalidad de la gestión urbana y sus mecanismos de actuación. Los mismos se iniciaron en la última década del siglo pasado con el reposicionamiento de agentes y actores productores de espacio en la ciudad.
Paisaje sonoro urbano “Soundwalk” como método de análisis integral.
Authors: Maristany Arturo Raúl
Published: March 2023

Este trabajo se orienta al estudio de las variables que influyen en la percepción acústica de los espacios exteriores, los tipos de sonidos, y el nivel de aceptación que los mismos producen, mediante el uso de descriptores acústicos y psicoacústicos. Los resultados alcanzados permiten verificar que el nivel sonoro objetivo por si mismo no es indicador suficiente de la calidad acústica de un espacio urbano, se identifican una serie de variables que influyen en la caracterización acústica de un ámbito urbano: la actividad desarrollada y su relación con los niveles de percepción de sonidos naturales, humanos y tecnológicos. El estudio de la calidad acústica en el área central de la ciudad de Córdoba permitió analizar las diferentes reacciones y grado de aceptación de los usuarios de espacios urbanos abiertos en los que las condiciones acústicas objetivas son similares. El enfoque implica un desarrollo metodológico integral que tenga en cuenta la interacción entre personas, sonido y contexto. Se propone un enfoque metodológico para el análisis del paisaje sonoro, basado en una mecánica práctica para la evaluación objetiva, la integración y la interrelación de cuatro descriptores acústicos seleccionados: nivel sonoro, sonoridad, nitidez y contenido de baja frecuencia, relevados mediante la técnica del soundwalk.

Hacia una perspectiva estructural de la urbanización popular en América Latina
Authors: Pírez Pedro
Published: March 2023

La ponencia propone un esquema analítico para estudiar la urbanización popular, dentro del contexto más amplio de la urbanización en las sociedades latinoamericanas significada por el predominio de las relaciones capitalistas. Identifica condiciones estructurales particulares que lo diferencian del modelo clásico de desarrollo del capitalismo. Para ello se basa en dos aportes previos: Uno sobre las peculiaridades de la urbanización latinoamericana a nivel estructural y otro con elementos para el análisis de los actores de la urbanización, sus lógicas de orientación y sus relaciones, que permite dinamizar al anterior. En su desarrollo se presenta una síntesis del esquema conceptual, identificando como aspectos estructurales a la heterogeneidad de modalidades de producción-consumo de la urbanización latinoamericana, la configuración de situaciones de solvencia-insolvencia en la población y el papel de la propiedad privada. Con esos elementos es posible definir teóricamente a la urbanización popular como un componente estructural que define claramente a la urbanización latinoamericana. Lo anterior se complementa con la exposición de la secuencia de la urbanización popular, identificando diferentes fases en las que pueden advertirse los actores sociales, sus lógicas y las relaciones que las definen en cada momento. Se finaliza el texto con algunas notas que pueden contribuir con este análisis.
Diseño experimental de elementos constructivos utilizando materiales reciclados, para viviendas de interés social. Síntesis de tesis doctoral.
Authors: Gaggino Rosana
Published: March 2023

Este artículo es una síntesis de una Tesis Doctoral de la Carrera de Doctorado en Ciencias de Diseño de la Facultad de Arquitectura, Urbanismo y Diseño de la Universidad Nacional de Córdoba, presentada en el año 2009. Trata sobre el desarrollo de un nuevo material para la construcción: el mortero elaborado con plásticos reciclados y cemento. Con este material se han fabricado ladrillos, bloques, placas y ladrillones que se utilizan como cerramiento no portante en viviendas. Estos elementos constructivos son más ecológicos que otros tradicionales porque se utilizan residuos como materia prima principal, colaborando así con la descontaminación del medio ambiente. La mayor parte de estos residuos hasta el presente son enterrados en predios municipales, sin utilidad alguna; o acumulados y quemados en basurales, produciendo degradación del entorno. Desde el punto de vista técnico, se logran elementos constructivos con ventajas con respecto a otros tradicionales (como por ejemplo ladrillos de tierra y bloques de hormigón) en lo que respecta a liviandad y aislamiento térmico. La importancia económica de la implementación de esta tecnología es que se reducirían gastos para los municipios en recolección y disposición final de residuos; y en general en la descontaminación del medio ambiente.
Perspectiva de abordaje en el desarrollo territorial: la región llanura (Córdoba, Argentina)
Authors: Crissi Aloranti Vanesa Soledad
Published: March 2023

En el estudio del territorio se considera importante su abordaje desde una visión sistémica-holística que analice las dimensiones naturales, sociales, económicas, culturales y político-institucionales, que resultan de la comprensión de lo territorial desde distintas escalas, jerarquizadas y en interacción.
En el afán de acercarnos a la consideración de dichas dimensiones, el objetivo de este trabajo es describir y analizar los escenarios de las comunas (asentamientos poblaciones de menos de 2.000 habitantes, Ley N° 8102/1991) de la región Llanura de la provincia de Córdoba, a través de los capitales territoriales planteados por Boisier.  Ello se materializa a partir de una revisión de perspectivas teóricas del desarrollo territorial, para luego proponer líneas estratégicas de acción en pos del desarrollo integral local-regional. Es menester señalar que los escenarios comunales de la región en estudio presentan realidades similares en relación a la conformación territorial, a las necesidades urbanas y problemas ambientales.
La investigación se realizó con el sustento de información cuantitativa y cualitativa que permitió el análisis exhaustivo junto al desarrollo de propuestas de acción. Las conclusiones expuestas buscan ampliar el abordaje para futuras investigaciones en capital sinergético desde la intervención y transformación de los territorios de estudio como componente del desarrollo territorial.
reflexión histórica sobre las materias científicas, tecnológicas y técnicas en la carrera de Arquitectura
Authors: Cravino Ana María
Published: March 2023

Este artículo corresponde a fragmentos de un capítulo de la Tesis Doctoral desarrollada en la FADU-UBA y defendida en 2015, dedicada a estudiar las transformaciones disciplinares en el interior de los planes de estudio de la carrera de arquitectura de la Universidad de Buenos Aires desde sus inicios hasta 1956. El trabajo aquí presentado expone, desde una perspectiva histórica, la evolución de las asignaturas del área conocida actualmente como de “Ciencias Básicas, Tecnología, Producción y Gestión”. Nuestro propósito inicial fue reflexionar sobre por qué se enseñó de tal o cual manera, qué alternativas se descartaron, cuáles fueron los contenidos, procedimientos y valores que se consideraron preferenciales y, principalmente, qué concepción de la enseñanza se defendía tácitamente. Para este fin analizamos, sin olvidar a los docentes, los programas de las asignaturas, los ejercicios que debieron realizar los alumnos, las temáticas desarrolladas -y las excluidas-, los marcos teóricos, la bibliografía utilizada, la correspondencia o confrontación con los modelos legitimados, la perduración de ciertas prácticas, las tradiciones y rupturas, todo ello para entender cuánto de lo mencionado aún perdura.
Políticas de hábitat, ¿en transición?
Authors: Palumbo Joseph , Toscani María de la Paz , Rosa Paula Cecilia , Martínez Araujo Zahiry
Published: March 2023

Uno de los aspectos más criticados de los modelos tradicionales de política habitacional ha sido el escaso margen que se abre para la participación de los sectores afectados, particularmente la población destinataria, limitando su efectividad y adecuación a las necesidades habitacionales reales. Esto se ha convertido en una demanda de las organizaciones sociales vinculadas al hábitat, y en años recientes emergió cierto consenso respecto a la necesidad de contemplar esta dimensión en las políticas e intervenciones estatales en materia de hábitat. Dichas demandas están siendo recogidas con mayor frecuencia en las políticas habitacionales, que en algunos casos definen nuevos canales y mecanismos para incorporar la participación de la población destinataria y las organizaciones sociales que la representan. El presente artículo se enfoca en dos iniciativas ejemplares en este sentido: la Ley 14.449 de Acceso Justo al Hábitat de la Provincia de Buenos Aires y la experiencia del Registro Nacional de Barrios Populares y la posterior Ley Nacional 27.453. Ofrecer una mirada sobre estos casos permitirá abrir interrogantes acerca de la posibilidad de una transición incipiente hacia otro modelo de gestión de la política habitacional, en el cual la participación de las organizaciones sociales posee mayor centralidad.
REASONS OF DONOR DEFERRAL FOR A SINGLE DONOR PLATELETPHERESIS IN A PUBLIC SECTOR BLOOD TRANSFUSION CENTRE OF LAHORE: A CROSS-SECTIONAL STUDY
Authors: Fateen Tooba , Sana Haseeb Khan  , Saima Farhan  , Amna Rani  , Rajia Liaqat  , Attiq Ur Rehman
Published: March 2023

Background and Objective: Plateletpheresis is a process by which platelets are extracted from the donor. Donor selection is critical since donors are the sole supply of blood available to satisfy demand. The goal of this study is to investigate the causes behind plateletpheresis donor deferral in order to ensure safe blood donation.
Materials and Methods: The research was carried out at the department of Haematology and Transfusion Medicine University of Child Health Sciences, The Children Hospital Lahore. 50 plateletpheresis donors who voluntarily came for donation were considered for the procedure as per guidelines and departmental standard operating procedure. The details of the procedure of plateletpheresis were explained to each donor. Donor questionnaire was filled including brief history, general physical examination, Haematological parameters such as haemoglobin and the donor blood screening was done to be considered fit for procedure. The reasons for deferral of donors were noted after all work up was done. Informed consent was taken before the procedure. Plateletpheresis was done using COM.TEC Cell Separator instrument.
Results: In this study 50 donors were included. Out of 50 donors 34 were approved for procedure and 16 were deferred due to different temporary and permanent reasons. The age of the donors were in between 18 to 50 years. Major reason for temporary deferral was poor venous access (n=7, 14%) followed by the low haemoglobin value (n=4, 8%). Other reasons for temporary deferral were history of medication (n=3, 6%), low platelet count (n=4,8%), history of blood transfusion (n=1, 2%), history of vaccination n=2, 4%), leucocytosis (n=1, 2%), underweight (n=4, 8%), fever (n=1, 2%), refusal after questionnaire (n=1, 2%), seropositive for malaria and VDRL (n=3, 6%), high blood pressure (n=1, 2%), and anxiety (n=1, 2%). Permanent reasons for deferral were seropositive for HbsAg (n=2, 4%), seropositive for HCV (n=4, 8%) and tattoo (n=1, 2%).
Conclusion: This study found a pattern of donor deferral in single donor platelet apheresis that was our experience in single centre.  In conclusion during the selection of donors, Transfusion services should be very careful related to donor safety measures and these causes of deferral should be kept in mind.

Published: March 2023

Background & Objective: Aplastic anemia is a rare and heterogeneous disorder. Literature shows inconsis- tencies in frequency and its clinico-hematological findings. Objective of this study was to assess frequency of different severity grades and clinico-hematological features in newly diagnosed cases of aplastic anemia in adults.

Methods: In this descriptive, cross-sectional study, conducted in Allama Iqbal Medical College Lahore from October 2021 through April 2022, a total of 100 diagnosed cases of acquired aplastic anemia were included. Modified Camitta's criteria were applied to assess the severity of aplastic anemia. Clinical features such as pallor, fever and bleeding manifestations were determined by history and physical examination. About 3ml whole blood was collected in EDTA vial and run for complete blood count on automated hematology analyzer for hematological Parameters (Hb, Platelets, total leukocyte count and absolute Neutrophil count). Data were entered and analyzed using SPSS version 20. Quantitative variables like age, Hb, TLC and platelet count were expressed as mean ±Standard deviation. Qualitative variables such as gender, severity of aplastic anemia and clinical features were expressed as percentages.

Results: In this study, 55% participants were male and 45% were female. All patients had pallor, 61% had fever and 66% had bleeding on presentation. Regarding severity of aplastic anemia, 56% were categorized as severe, 24% as very severe and 20% were as non severe aplastic anemia.

Conclusion: Severe aplastic anemia is frequent among male population and at younger age. This information has prognostic implications. Therefore, all patients with aplastic anemia should be assessed for severity for further clinical management.
Workshop Program Anti Perundungan Berbasis Sekolah

Published: March 2023

Bullying atau perundungan merupakan perilaku oleh individu atau kelompok, berulang dari waktu ke waktu, yang dengan sengaja menyakiti individu atau kelompok lain baik secara fisik maupun emosinal dan terjadi di mana ada ketidakseimbangan kekuatan yang berbeda antara pelaku dan korban. Beberapa program pencegahan perundungan telah terbukti secara umum efektif dalam mengurangi perudungan di kalangan masyarakat. Namun, efeknya relatif kecil dalam berbagai penelitian eksperimen dan kelompok usia. Program yang lebih intensif dan durasinya lebih lama (baik untuk anak maupun guru) lebih efektif, begitu juga program yang mengandung lebih banyak komponen. Beberapa komponen program dikaitkan dengan ukuran efek yang besar, termasuk pelatihan atau pertemuan orang tua dan pelatihan guru. Hal ini menjadi landasan kegiatan pengabdian masyarakat yang tujuan untuk sosialisasi program pencegahan perundungan berbasis sekolah di SMK Tuban. Metode kegiatan pengabdian masyarakat menggunakan beberapa tahapan, yaitu identifikasi kebutuhan, persiapan, pelaksanaan dan evaluasi. Berdasarkan diskusi yang dilakukan, ditemuakn beberapa program yang paling banyak digunakan di Indonesia yaitu program disiplin positif, program ROOTS Indonesia, dan program buddy.
Kumusta ka? Challenges, mental health and well-being assessment among DNSC employees during the COVID-19 pandemic
Authors: Law-Ay Sadie , Fermil Florie Ann , Agod Joena Marie
Published: March 2023

The study aimed to identify the work challenges encountered by the employees due to the pandemic, their current depression, anxiety, stress, mental well-being, and perception of the institution’s capacity to manage the current crisis and mental healthcare needs. Online surveys were utilized as a method. The results revealed that the top on the list of the work challenges encountered by most of the employees due to the pandemic was: internet connection, too many distractions at home, balancing work and personal life, general anxiety of getting infected, and technology-based communication like virtual meetings, while for teaching personnel doing modules, checking and monitoring students and conducting online classes were among their concerns. Out of 73 sample population, 64% were at normal level, 36% were at mild to extreme levels in depression subscale. About 58% were at the normal level for the anxiety subscale while 42% fell on the mild to extreme levels. For the stress subscale, 23% were mild to severe, and the rest were on a normal level. As to the wellbeing level, 22% of the samples were in the low level, 67% were in the average, and 11% were in the high level. Though most of the employees were confident towards the institution’s leaders in handling the crisis, they still felt worried about the impact of the pandemic on the institution. The employees strongly agreed on the necessity of the presence of mental health professionals in the institution and suggested conducting debriefing/processing to ease the mental and psychological burden brought by this pandemic.

A low-dose tablet formulation, containing a potent Benzodiazepine derivative Alprazolam was developed, considering the achievement of appropriate content uniformity of the active substance in powder blends and tablets as a major challenge. Two different types of lactose monohydrate (Tablettose 80 and Granulac 200) and two different types of dry mixing processes (high-shear mixing and "in bulk" mixing) were employed. To evaluate the influence of the variables (mixing speed, mixing time, filling level of the high-shear and cube mixer, lactose monohydrate type) and their interactions upon the response (content uniformity of Alprazolam in the powder blends), a Factorial 2 4 design (with 4 factors at 2 levels in 1 block) was generated for each type of mixer. For high-shear dry mixing the Response Surface, D-optimal Factorial 2 4 design (with 2 replications and 31 experiments) was used, while for the "in bulk" dry mixing the Response Surface, Central Composite Factorial 2 4 design (with 34 experiments) was used. The process parameters for the high-shear mixer were varied within the following ranges: filling level of 70-100%, impeller mixing speed of 50-300 rpm and mixing time of 2-10 minutes. For the cube mixer the following process parameter ranges were employed: filling level of 30-60%, mixing speed of 20-390 rpm and mixing time of 2-10 minutes. Raman spectroscopy in conjunction with a validated Partial Least Square (PLS) regression model was used as a Process Analytical Technology (PAT) tool for Alprazolam content determination and content uniformity monitoring. The DoE model was further employed to optimize the powder blending process in regard to the achievement of appropriate Alprazolam content uniformity using high-shear mixing and Tabletosse 80 as filler. The desirability function revealed that the following process parameters: a mixing time of 2 minutes, a mixing speed of 300 rpm and a 70% filling level of the mixer would produce powder blends with the lowest variability in Alprazolam content. The three independent lab batches of low-dose Alprazolam tablets, produced with high-shear mixing using these process parameters, conformed to the requirements of the European Pharmacopoeia for content (assay) of Alprazolam and uniformity of the dosage units.

The 1st trimester of pregnancy is accompanied with changes in different biochemical and hematological parameters. Analyses scheduled to be performed in the 1st trimester are complete blood count, blood group, Rh factor and the double test. Many experts also suggest the determination of lipid status parameters as a routine analysis in the early pregnancy. Reliable data about maternal and fetal health can be obtained by the assessment of the above-mentioned parameters. They may be helpful in assessing the risk for pregnancy complication development and/or perinatal adverse outcomes.
Design and development of a novel tunable electrorheological fluid (ERF) damper-foundation to attenuate residual vibrations in machine tools
Authors: Jadhav Abhijitkumar , Zope Sanjay , Malagi Ravindra , Suryawanshi Deepali
Published: March 2023

Residual vibrations in machine tools hamper accuracy and productivity. The attenuation of residual vibrations has been an industrial concern for decades. Meanwhile, the residual vibrations' vibration pattern reveals that the support foundation's damping capabilities predominantly influence them. Therefore, inserting dampers in any other location on a machine tool (such as a machine column) is ineffective. Hence, the scope of inserting the damper into the machine foundation needs to be verified. However, conventional machine mounting systems (concrete foundation and rubber mounts) equally respond to all variable inputs. Both these flocks resulted in inadequate dampening and perhaps poor accuracy. This paper provides a first-generation model of a semiactive-viscous damper (ERF damper-foundation) with tunable damping facilitating machine installation. Controlled experimentation by exposing the developed damper foundation to excitations of medium duty lathe machine confirms its effectiveness and obtains over 48% attenuation compared to a conventional concrete foundation.
Control of direct current motor by using artificial neural networks in Internal model control scheme
Authors: Perišić Natalija , Jovanović Radiša
Published: March 2023

In this research, control of the Direct Current motor is accomplished using a neuro controller in the Internal Model Control scheme. Two Feed Forward Neural Networks are trained using historical input-output data. The first neural network is trained to identify the object's dynamic behavior, and that model is used as an internal model in the control scheme. The second neural network is trained to obtain an inverse model of the object, which is applied as a neuro controller. Experiment is conducted on the real direct current motor in laboratory conditions. Obtained results are compared to those achieved by implementing the Direct Inverse Control method with the same neuro controller. It was demonstrated that the proposed control method is simple to implement and the system robustness is achieved, which is a great benefit, aside from the fact that no mathematical model of the system is necessary to synthesize the controller of the real object.
ADAPTATION OF DOMAIN-SPECIFIC TRANSFORMER MODELS WITH TEXT OVERSAMPLING FOR SENTIMENT ANALYSIS OF SOCIAL MEDIA POSTS ON COVID-19 VACCINE
Authors: Bansal Anmol , Choudhry Arjun , Sharma Anubhav , Susan Seba
Published: March 2023

Covid-19 has spread across the world and many different vaccines have been developed to counter its surge. To identify the correct sentiments associated with the vaccines from social media posts, this paper aims to fine-tune pre-trained transformer models on tweets associated with different Covid vaccines, specifically RoBERTa, XLNet and BERT which are recently introduced state-of-the-art bi-directional transformer models, and domain-specific transformer models BERTweet and CT-BERT that are pre-trained on Covid-19 tweets. We further explore the option of data augmentation by text oversampling using LMOTE to improve the accuracies of these models, specifically, for small sample datasets where there is an imbalanced class distribution among the positive, negative and neutral sentiment classes. Our results summarize our findings on the suitability of text oversampling for imbalanced, small sample datasets that are used to fine-tune state-of-the-art pre-trained transformer models, and the utility of having domain-specific transformer models for the classification task.

Published: March 2023

People at risk for diabetic foot ulcer (DFU) often misunderstand why foot ulcers develop and what self-care strategies may help prevent them. The etiology of DFU is complex and difficult to communicate to patients, which may hinder effective self-care. Thus, we propose a simplified model of DFU etiology and prevention to aid communication with patients. The Fragile Feet & Trivial Trauma model focuses on two broad sets of risk factors: predisposing and precipitating. Predisposing risk factors (eg, neuropathy, angiopathy, and foot deformity) are usually lifelong and result in “fragile feet.” Precipitating risk factors are usually different forms of everyday trauma (eg, mechanical, thermal, and chemical) and can be summarized as “trivial trauma.” We suggest that the clinician consider discussing this model with their patient in three steps: 1) explain how a patient’s specific predisposing risk factors result in fragile feet for the rest of life, 2) explain how specific risk factors in a patient’s environment can be the trivial trauma that triggers development of a DFU, and 3) discuss and agree on with the patient measures to reduce the fragility of the feet (eg, vascular surgery) and prevent trivial trauma (eg, wear therapeutic footwear). By this, the model supports the communication of two essential messages: that patients may have a lifelong risk of ulceration but that there are health-care interventions and self-care practices that can reduce these risks. The Fragile Feet & Trivial Trauma model is a promising tool for aiding communication of foot ulcer etiology to patients. Future studies should investigate whether using the model results in improved patient understanding and self-care and, in turn, contributes to lower ulceration rates.
Severe Calcification of Femoral Arteries Causes Tourniquet Failure Accompanied by Massive Bleeding

Tourniquet failure is attributed to inadequate tourniquet pressure, inadequate exsanguination, failure to compress medullary vessels within the bone, and incompressible calcified arteries. We herein report a case of massive bleeding using a properly functioning tourniquet in a patient who had bilateral calcified femoral arteries. When incompressible calcified arteries are present, the inflated tourniquet cuff fails to adequately compress the underlying artery, yet acts as an efficient venous tourniquet, which leads to an increase in bleeding. It is therefore critical to preoperatively confirm the effectiveness of the tourniquet in arterial occlusion in patients with severe arterial calcification.
How Effective Are Devices in the Management of Onychomycosis?: A Systematic Review

Onychomycosis is the most common nail disorder, with a global prevalence of approximately 5.5%. It is difficult to cure on both short-term and long-term bases. The most common treatments include the use of oral or topical antifungals. Recurrent infections are common, and the use of systemic oral antifungals raises concerns of hepatotoxicity and drug-drug interactions, particularly in patients with polypharmacy. A number of device-based treatments have been developed for onychomycosis treatment, to either directly treat fungal infection or act as adjuvants to increase the efficacy of topical and oral agents. These device-based treatments have been increasing in popularity over the past several years, and include photodynamic therapy, iontophoresis, plasma, microwaves, ultrasound, nail drilling, and lasers. Some, such as photodynamic therapy, provide more direct treatment, whereas others, such as ultrasound and nail drilling, aid the uptake of traditional antifungals. We conducted a systematic literature search investigating the efficacy of these device-based treatment methods. From an initial result of 841 studies, 26 were deemed relevant to the use of device-based treatments of onychomycosis. This review examines these methods and provides insight into the state of clinical research for each. Many device-based treatments show promising results, but require more research to assess their true impact on onychomycosis.
Genetic dissection of mutual interference between two consecutive learning tasks in Drosophila

Animals can continuously learn different tasks to adapt to changing environments and, therefore, have strategies to effectively cope with inter-task interference, including both proactive interference (Pro-I) and retroactive interference (Retro-I). Many biological mechanisms are known to contribute to learning, memory, and forgetting for a single task, however, mechanisms involved only when learning sequential different tasks are relatively poorly understood. Here, we dissect the respective molecular mechanisms of Pro-I and Retro-I between two consecutive associative learning tasks in Drosophila. Pro-I is more sensitive to an inter-task interval (ITI) than Retro-I. They occur together at short ITI (<20 min), while only Retro-I remains significant at ITI beyond 20 min. Acutely overexpressing Corkscrew (CSW), an evolutionarily conserved protein tyrosine phosphatase SHP2, in mushroom body (MB) neurons reduces Pro-I, whereas acute knockdown of CSW exacerbates Pro-I. Such function of CSW is further found to rely on the γ subset of MB neurons and the downstream Raf/MAPK pathway. In contrast, manipulating CSW does not affect Retro-I as well as a single learning task. Interestingly, manipulation of Rac1, a molecule that regulates Retro-I, does not affect Pro-I. Thus, our findings suggest that learning different tasks consecutively triggers distinct molecular mechanisms to tune proactive and retroactive interference.
Research on fault location algorithm of TPSS based on PSOA
Authors: Jia Yunqian
Published: March 2023

It is extremely important to research traction power supply system (TPSS) protection technology in order to ensure the safe operation of urban rail transit. A TPSS includes rails, return cables, rail potential limiting devices, one-way conducting devices, drainage cabinets, ballast beds, and tunnel structural reinforcements. In urban rail transit, on the basis of the dynamic characteristics of the TPSS, a fault location algorithm based on particle swarm optimization algorithm (PSOA) is developed. An evaluation of multi-point monitoring data is proposed based on fuzzy processing of the average value of polarization potential forward deviation and multi-attribute decision-making. Monitoring points and standard comparison threshold values are determined by the distribution law of stray currents. In conjunction with the actual project, the model is trained using field measured data. Based on the results, TPSSOA is able to achieve optimal discharge current control, reduce network losses and improve power quality. Moreover, the reconstruction results demonstrate the high usability of the proposed method, which will provide guidance to design the TPSS in the future.

Published: March 2023

Background

An automatic bathing robot needs to identify the area to be bathed in order to perform visually-guided bathing tasks. Skin detection is the first step. The deep convolutional neural network (CNN)-based object detection algorithm shows excellent robustness to light and environmental changes when performing skin detection. The one-stage object detection algorithm has good real-time performance, and is widely used in practical projects.

Methods

In our previous work, we performed skin detection using Faster R-CNN (ResNet50 as backbone), Faster R-CNN (MobileNetV2 as backbone), YOLOv3 (DarkNet53 as backbone), YOLOv4 (CSPDarknet53 as backbone), and CenterNet (Hourglass as backbone), and found that YOLOv4 had the best performance. In this study, we considered the convenience of practical deployment and used the lightweight version of YOLOv4, i.e., YOLOv4-tiny, for skin detection. Additionally, we added three kinds of attention mechanisms to strengthen feature extraction: SE, ECA, and CBAM. We added the attention module to the two feature layers of the backbone output. In the enhanced feature extraction network part, we applied the attention module to the up-sampled features. For full comparison, we used other lightweight methods that use MobileNetV1, MobileNetV2, and MobileNetV3 as the backbone of YOLOv4. We established a comprehensive evaluation index to evaluate the performance of the models that mainly reflected the balance between model size and mAP.

Results

The experimental results revealed that the weight file of YOLOv4-tiny without attention mechanisms was reduced to 9.2% of YOLOv4, but the mAP maintained 67.3% of YOLOv4. YOLOv4-tiny’s performance improved after combining the CBAM and ECA modules, but the addition of SE deteriorated the performance of YOLOv4-tiny. MobileNetVX_YOLOv4 (X = 1, 2, 3), which used MobileNetV1, MobileNetV2, and MobileNetV3 as the backbone of YOLOv4, showed higher mAP than YOLOv4-tiny series (including YOLOv4-tiny and three improved YOLOv4-tiny based on the attention mechanism) but had a larger weight file. The network performance was evaluated using the comprehensive evaluation index. The model, which integrates the CBAM attention mechanism and YOLOv4-tiny, achieved a good balance between model size and detection accuracy.
