Metode penelitian yang digunakan adalah Security Policy Development Life Cycle (SPDLC) dengan melewati beberapa tahapan, yaitu:. Analysis, Desain, Implementation, Enforcement, Enchancement. Hasil penelitian menyimpulkan bahwa serangan yang dilakukan oleh penyerang pada jaringan dapat diketahui dan ditangani sebelum kerusakan yang lebih luas terjadi serta penggunaan wireshark yang dapat menganalisa serangan dengan baik melalui flow graph yang disediakan.
bienestar subjetivo de los mayores en España:
Authors: Ortega Gaspar Marta , López Narbona Ana María , Juárez Marta
Published: March 2022

España se encuentra entre los países con la tasa más elevada de esperanza de vida del mundo. Esto, junto a la baja y estancada tasa de natalidad, lo hacen uno de los más envejecidos. En este contexto, el estudio del bienestar de los mayores cobra especial importancia. Este trabajo ofrece una revisión de la literatura sobre los estudios centrados en el análisis del bienestar subjetivo de los mayores con especial atención al caso de España. En concreto, se focalizan los análisis de las dimensiones del bienestar subjetivo. Tras la investigación se comprueba que son escasos los estudios que se centran en los mayores y en su bienestar subjetivo, sobre todo los relacionados con la renta o situación económica del hogar. Esta carencia plantea serios problemas a la hora de implementar políticas sociales que favorezcan la protección de este colectivo en situación de vulnerabilidad.
Prácticas virtuales de Topografía (Surveying Game)
Authors: Hidalgo Sánchez Francisco Manuel , Barrera Vera José Antonio , Pérez Romero Antonio Miguel
Published: March 2022

Las prácticas de topografía consisten en su mayor parte en levantamientos de terrenos en donde se posiciona el operador sobre una serie de puntos característicos para, mediante GPS o Estación total obtener las coordenadas del punto y así establecer una red de puntos que definen la geometría de la superficie del terreno. Al ser una práctica que ha de hacerse en campo presenta las dificultades del desplazamiento de aparatos y alumnos al terreno en cuestión. Se trata además de una actividad que difícilmente se puede aprender si no es de una manera práctica sobre el terreno, por tanto es un punto crítico en la enseñanza de titulaciones que cuentan con la asignatura de topografía. Esta circunstancia adquiere características extremas con la pandemia del COVID19 que dificulta la disposición de aparatos topográficos y la formación de equipos de trabajo de campo. Es por ello que el objetivo de la aplicación es desarrollar una aplicación de realidad aumentada que simule la práctica de levantamiento en campo, a modo de video juego 3D cuya propósito sea obtener el levantamiento de un terreno obteniendo mayor o menor puntuación en función de la adecuación del levantamiento obtenido al modelo inicial (terreno virtual proporcionado).

Ese recurso está dirigido a estudiantes de la asignatura, Topografía y Replanteos de las titulaciones de Grado en edificación, Ingeniería agronómica, ingeniería civil, etc, y en general a todos los estudiantes o profesionales que quieran aprender la técnica práctica del levantamiento de terrenos.

Es un recurso idóneo para explicar la metodología a seguir en campo para realizar un levantamiento topográfico y seleccionar los puntos idóneos (puntos notables y líneas de rotura) para obtener sus coordenadas y a partir de ellos obtener un modelo digital lo más fiel posible.
Treatment of AIDS: Development of Medicine by Innovation with Special Emphasis on Protease Inhibitors
Authors: Kundu Agnita
Published: March 2022

:In the light of the recent events in the world concerning COVID-19 virus, it is important to review the challenges faced by the world by another pandemic, AIDS. The painstaking research by the scientists, the pharmaceutical companies, the medical professionals have led to this day when AIDS patients are living their whole life span. Though we do not have any vaccine for AIDS but by intelligent use of medication, we have been able to combat the disease to a large extent. HIV is a RNA virus, whose treatment is mainly done by finding the structure and function of the proteins that are vital to its life cycle. Designing a drug/inhibitor to make those proteins ineffective constitutes the next step. WHO has recognized AIDS as a pandemic almost 40 years back but the world is yet to find a cure or a vaccine. The current treatment method is called HAART, Highly Active Anti Retroviral Therapy, where different types of inhibitors,eg. Reverse Transcriptase inhibitors, Protease inhibitors; each arresting a different important protein are given in combination. The virus replicates very fast and forms mutations which render it ineffective to the inhibitors thus resistance to the inhibitors develop. Hence development of new types of inhibitors is crucial to the problem. There are certain similarities between AIDS and COVID-19, both in terms of the attacking virus and effective medication, which make it more important than ever that the research on HIV is revisited and knowledge we gain from it is used to battle the new pandemic. © 2020 iGlobal Research and Publishing Foundation.

Vanishing Traces: Evolution of Autobiographical Practices on the Internet
Authors: Więckiewicz-Archacka Marta
Published: March 2022

This article analyses one of the many directions of change in online autobiographical practices, i.e. the decrease in the importance of autobiographical content preservation and archiving with the simultaneous increased popularity of ephemeral content, e.g. that which is automatically deleted after a single viewing. This trend in autobiographical digital practices is illustrated with significant examples of new media formats such as homepages, blogs as well as entries on the social media platform Facebook and the application Snapchat. The article enumerates stages of change with reference to various communication tools, but it should be noted that the evolutionary process is continuous and its stages overlap. The indicated direction of change in online autobiographical practices, determined by the developmental realities of new media, is analysed in connection with processual media theory, as well as the concept of an ephemeral turn in a digital environment.

To połącznie edukacji z działalnością teatralną wydaje się trafną receptą na aktualne wyzwania procesu socjalizacji młodzieży szkolnej.
Poland as the Bastion of Christianity and the Issue of a Union with the Orthodox Church
Authors: Smołucha Janusz
Published: March 2022

When the Ottoman Turks began their conquest of further Balkan countries in the second half of the 14th century, they were opposed by Hungary, which came to known as the bastion of Christianity. The article analyses subsequent events of the 15th and 16th centuries when the term was first applied to the Kingdom of Poland. Poland’s greatest involvement in the war against the Muslims was during the reign of Ladislaus III of Hungary, who died in 1444 at the Battle of Varna. Under his successor, Kazimierz Jagiellończyk, Poland managed to avoid military conflict with Turkey, though it waged constant war with their allies, the Tatars. The first Turkish invasions of Poland followed the defeat in Bukovina in the autumn of 1497. In the ensuing decades, Poland was forced to renew truces with Turkey every few years, which drained the state’s coffers yet failed to protect it from the devastating Tartar invasions. After the fall of Hungary at the Battle of Mohács in 1526, Poland found itself on the front line, exposed to direct attack by the armies of the Padishah. The Holy See joined the defense against the Islamic threat, hoping to convince the Grand Duchy of Moscow to go to war with Turkey. Papal diplomacy was also centered on the followers of the Orthodox Church living within the borders of the Republic, which resulted in the Union of Brest in 1596.

Authors: V Poongodi , S Kalavathi , K Renuka , A Lokesmaran , P Rajaveni
Published: March 2022

Background: High-risk pregnancy is one which is complicated by factor or factors that adversely affects the pregnancy outcome (maternal,
perinatal or both). Only 10-30% of the mothers in antenatal period can be classied as high risk but they account for 70-80% of perinatal mortality
and morbidity. Every year nearly 529000 women die globally due to pregnancy related causes. Hence, the current study was to evaluate the
effectiveness of computer assisted teaching on knowledge regarding bioethical issues in high risk pregnancy and its outcome among antenatal
women.
Materials & Method: A quantitative research approach and pre – experimental one group pre-test post-test research design was adopted.
Purposive sampling technique was used to select 30 antenatal women with high risk pregnancy who met the inclusion criteria. Pre-test knowledge
was assessed by structured questionnaire. After implementation of computer assisted teaching post test knowledge was assessed by same
structured questionnaire which has been used in pre-test. The data were analyzed by using descriptive and inferential statistics like frequency,
percentage, mean, standard deviation and paired't' test.
Results:The results revealed that in pre-test 30 (100%) had inadequate knowledge and no one had moderately adequate and adequate knowledge.
In post-test 12 (40%) had adequate knowledge, 18 (60%) had moderately adequate knowledge and no one had inadequate knowledge. The pre and
post-test mean knowledge score were 9.13±1.358 and 21.67±3.273 respectively. The improvement of knowledge is statistically tested by paired ttest which was found to be highly statistically signicant at p<0.001 level.
Conclusion:Improving the knowledge on bioethical issues helps to reduce the incidences of high risk pregnancy and its outcomes

Exploring Coherence among Sri Lankan CFL Learners in Chinese-English Translation: Decoding and Interpreting of Culture-loaded Content
Authors: Dassanayake Noel
Published: March 2022

Modern translation has shifted from its traditional approach of merely translating linguistic features towards a more culturally sensitive approach, which further considers the sociolinguistic spaces of the source text in producing the target text. This significant theoretical transformation has demanded the translator to play a more comprehensive role, which involves intercultural and sociolinguistic competencies apart from language competence. Subsequently, maintaining cohesion and coherence within and among texts also demands a heavier effort from the translator with neologisms being created frequently. The present study has been an attempt to identify the core issues pertaining to lexical coherence in translating from Chinese sources in Sri Lankan context using sample texts translated by Sri Lankan CFL (Chinese as a Foreign Language) learners. 20 culture-loaded lexical items were examined for coherence using a plagiarism checker and compared with Google and Baidu translation outputs of the source text. The results manifest that there is significant coherence among the target texts but coherence is a result of excessive use of machine translation, especially Google translate(?=94.67). 5-10 clusters were the most frequent clusters with an average of 21.73 clusters. < 10 word clusters have recorded an average of 19.07 whereas> 5 word clusters have recorded an average of 12.60.The highest number of clusters is recorded in text 5 with 44 clusters of <10 words. The highest number of translated variants of the same cultural term of the selected word list (n=20) is 4 while 70% (n=14) of the selected terms were only translated into either 1 or 2 variants. While machine translation is perceived as a constructive instrument under proper management, vigilant use of footnotes and end notes is perceived as a viable solution for reducing misinterpretation, vagueness and confusion in translating culture-loaded lexical items.

This study assessed how liquidity influenced the market value of 12 listed Nigerian Banks within the range of 2011 and 2019 with 108 observations. Data was generated from certified annual reports of selected banks. The study employed descriptive and multiple regressions techniques to analyse data while relevant diagnostic tests were conducted to validate data. The result indicated that liquidity had a negative significant influence on earnings per share (EPS) and divided yield (D/y) respectively. Bank size had a positive significant influence on the (EPS). On the other hand, bank size had a negative significant influence on the (D/y). Leverage gave us the positive insignificant influence on the (EPS) but it had a positive significant association with (D/y) respectively. The study concluded that negative effect of liquidity can lead to a decline in the earnings and reduce the growth of investment thereby has adverse effects on dividend yield to shareholders.

Published: March 2022

This study carried out an empirical test of stochastic dominance application on portfolio selection in the Nigerian stock market. December daily stock price of ten (10) listed insurance firms in the period 2014 to 2020 were selected and tested for stochastic dominance occurrence. The findings indicate that the selection of firm stock followed the Markowitz mean-variance and risk preference behavior of investors in the stock market. It also shows that two (2) firm stocks were first order stochastically dominant (FSD), four (4) stocks of firms were second order stochastically dominant while nine (9) stocks were third order stochastically dominant (TSD) in the period after the stock market meltdown in Nigeria. The study recommends that future researchers should empirically investigate portfolio dominance on a sector by sector basis. This will guide potential investors at selecting securities on the basis of mean-variance and utility function.

Published: March 2022

Background - The chase to improve the quality of life has stimulated desirable changes in research to design and develop a new drug and enhance its safety and effectiveness. Thus, there is a gradual rise in demand to develop susceptible and specific analytical techniques for newly developed drugs. Thus, analysts are striving very hard to develop new and efficient analytical methods to achieve these targets.

Main body of abstract - Analytical methods that analyze drug compounds in a given matrix need to be optimized and validated to ensure excellent selectivity, sensitivity, ease of use, speed of analysis, less expensive, and efficient analytical procedures. Developing a new analytical method should be considered critical, based on availability and accurate handling of different instruments. This review is a genuine venture of compiled literature of earlier and recent trends in the method developments for Cilnidipine (CLD) analysis alone and in combination with other drugs. It provides an in-depth assortment of practical aspects of various analytical techniques published for CLD.

Conclusion - High-performance liquid chromatography and ultraviolet spectroscopy have been found the most acceptable for the analysis of CLD. Stability indicating studies and impurity profiling of CLD also prevailed in the assembled literature. Scanty work was observed with capillary electrophoresis, Fourier transform-infrared spectroscopy, and electroanalytical methods to analyze CLD. Applications mentioned for CLD are significant in their particular field and contribute to analytical assay in future endeavours.

Keywords- Cilnidipine, Bioanalytical method, Stability indicating method, HPLC, Spectrophotometry.

Published: March 2022

Introducción: Un número importante de pacientes que ingresan al programa de diálisis peritoneal reciben simultaneamente la noticia de que tienen enfermedad renal crónica en etapa terminal y requieren diálisis peritoneal. Para muchos de ellos la noticia es inesperada y desconsoladora, ya que tienen que acceder a la diálisis para poder seguir viviendo. Material y Método: Estudio cualitativo, descriptivo con enfoque fenomenológico. De 106 pacientes incidentes del programa de diálisis peritoneal ambulatoria a quienes se les solicitó consentimiento informado para contestar el instrumento (Coping Inventory Strategies), se seleccionaron 14 pacientes que relataron sus vivencias respecto a su diagnóstico de enfermedad renal crónica y la necesidad urgente de diálisis peritoneal. Se les pidió que escribieran en una cuartilla cómo enfrentaron la noticia de insuficiencia renal crónica y requerir diálisis peritoneal. Resultados: Se incluyeron en el estudio a 14 pacientes, con edad comprendida entre 41 y 61 años, y el 66% fueron mujeres. Se identificaron tres categorías y siete subcategorías: sociolaboral (estigma social e incertidumbre por el trabajo); actitud ante la muerte (resignación y sentimiento de culpa) y acompañamiento familiar (toma de decisiones, motivación y apoyo). El mayor número de pacientes se ubicó en la categoría de actitud ante la muerte y en la subcategoría de resignación como estrategia de afrontamiento. Conclusiones: Los pacientes describieron la fase en la que se enteraron de su diagnóstico y el ingreso a diálisis peritoneal como el momento más difícil y traumático, manifestaron sentimientos de angustia, limitaciones personales o sociales y reconocieron la dependencia del apoyo familiar.

Published: March 2022

We have investigated the low-temperature magnetoresistive properties of a thin epitaxial Pd0.92Fe0.08 film at different directions of the current and the applied magnetic field. The obtained experimental results are well described within an assumption of a single-domain magnetic state of the film. In a wide range of the appled field directions, the magnetization reversal proceeds in two steps via the intermediate easy axis. An epitaxial heterostructure of two magnetically separated ferromagnetic layers, Pd0.92Fe0.08/Ag/Pd0.96Fe0.04, was synthesized and studied with dc magnetometry. Its magnetic configuration diagram has been constructed and the conditions have been determined for a controllable switching between stable parallel, orthogonal, and antiparallel arrangements of magnetic moments of the layers.

Applying the language acquisition model to the solution small language processing tasks
Authors: Kachkou Dz. I.
Published: March 2022

The problem of building a computer model of a small language was under solution. The relevance of this task is due to the following considerations: the need to eliminate the information inequality between speakers of different languages; the need for new tools for the study of poorly understood languages, as well as innovative approaches to language modeling in the low-resource context; the problem of supporting and developing small languages.

There are three main objectives in solving the problem of small natural language processing at the stage of describing the problem situation: to justify the problem of modeling language in the context of resource scarcity as a special task in the field of natural languages processing, to review the literature on the relevant topic, to develop the concept of language acquisition model with a relatively small number of available resources. Computer modeling techniques using neural networks, semi-supervised learning and reinforcement learning were involved.

The paper provides a review of the literature on modeling the learning of vocabulary, morphology, and grammar of a child's native language. Based on the current understanding of the language acquisition and existing computer models of this process, the architecture of the system of small language processing, which is taught through modeling of ontogenesis, is proposed. The main components of the system and the principles of their interaction are highlighted. The system is based on a module built on the basis of modern dialogical language models and taught in some rich-resources language (e.g., English). During training, an intermediate layer is used which represents statements in some abstract form, for example, in the symbols of formal semantics. The relationship between the formal recording of utterances and their translation into the target low-resource language is learned by modeling the child's acquisition of vocabulary and grammar of the language. One of components stands for the non-linguistic context in which language learning takes place.

This article explores the problem of modeling small languages. A detailed substantiation of the relevance of modeling small languages is given: the social significance of the problem is noted, the benefits for linguistics, ethnography, ethnology and cultural anthropology are shown. The ineffectiveness of approaches applied to large languages in conditions of a lack of resources is noted. A model of language learning by means of ontogenesis simulation is proposed, which is based both on the results obtained in the field of computer modeling and on the data of psycholinguistics.

TÓM TẮT

Chúng tôi báo cáo hai trường hợp trẻ tiền sử khoẻ mạnh, nhập viện tại khoa cấp cứu, là các trường hợp nhiễm SARS-CoV-2 với biểu hiện viêm thanh khí phế quản cấp nặng đầu tiên ở bệnh viện chúng tôi. Cả hai trường hợp (9 tháng và 8 tháng tuổi) đều khởi phát với biểu hiện không đặc hiệu ở đường hô hấp trên sau đó tiến triển nặng lên với tiếng ho ông ổng kèm biểu hiện thở rít khi nằm yên và suy hô hấp. Hai trường hợp đều cho kết quả dương tính với SARS-CoV-2, thực hiện bằng test nhanh kháng nguyên với mẫu bệnh phẩm được lấy từ dịch mũi họng. Cả hai trường hợp đều cho thấy đáp ứng không đáng kể với liều khí dung epinephrine đầu tiên và cần lặp lại. Các bệnh nhân trên đều được sử dụng hơn một liều dexamethasone tiêm tĩnh mạch, bởi vì mức độ cải thiện triệu chứng kém sau liều đầu tiên, điều này không thường thấy trong các trường hợp viêm thanh khí phế quản cấp ở bệnh viện chúng tôi. Kháng sinh được sử dụng ở cả hai trường hợp. Cả hai trẻ đều ổn định và ra viện sau thời gian điều trị. Việc xác định nguyên nhân thường không cần thiết trong viêm thanh khí phế quản cấp, tuy nhiên qua các trường hợp trên, xét nghiệm phát hiện SARS-CoV-2 nên được cân nhắc thực hiện ở những trẻ biểu hiện khó thở thanh quản, điều này có giá trị trong việc tiên lượng cũng như các biện pháp cách ly, phòng bệnh. Tuy dữ liệu còn hạn chế, nhưng qua các trường hợp chúng tôi đưa ra gợi ý rằng SARS-CoV-2 có thể gây biểu hiện viêm thanh khí phế quản cấp nặng và đáp ứng với điều trị chậm hơn so với các trường hợp điển hình.

ABSTRACT

SEVERE CROUP IN CHILDREN INFECTED WITH SARS-COV-2

We describe two previously healthy children, admitted to our emergency department (ED), as the first documented cases of severe croup as a manifestation of SARS-CoV-2 infection in our hospital. Both cases (ages 9 months and 8 months) presented with non-specific upper-respiratory-tract symptoms that developed into a barky cough with associated stridor at rest and respiratory distress. All were diagnosed with SARS-CoV-2 by antigen Rapid test from nasopharyngeal samples. Each received multiple doses of nebulized racemic epinephrine with minimal to no improvement shortly after medication. All were admitted and received several doses of dexamethasone, an atypical treatment occurrence in our hospital, due to each patient's prolonged duration of symptoms. Antibiotics were used for both cases. All patients were eventually discharged. Pathogen testing is usually not indicated in croup, but with “COVID-19 croup,” SARS-CoV-2 testing should be considered given the prognostic significance and prolonged quarantine implications. Our limited experience with this newly described COVID-19 croup condition suggests that cases can present with significant pathology and might not improve as rapidly as those with typical croup.

BACKGROUND: Childhood obesity is considered a risk factor for chronic diseases later in life. Phthalates (phthalate acid esters), predominant constituents of plasticizers, are well-thought-out global environmental contaminants.

AIM: This study aims to investigate the relationship between obesity and urinary phthalates in Egyptian children.

MATERIALS AND METHODS: This cross-sectional study included 210 children; 71 children were obese. Age ranged between 8.8 and 16 years with a mean of 12.93 ± 1.29 years. Sociodemographic data were collected. Clinical examination included measuring body weight, height, waist and hip circumferences (WC and HC), and calculation of body mass index (BMI). The lipid profile was analyzed. Urine samples were tested for phthalates levels using high-performance liquid chromatography.

RESULTS: Urinary phthalates metabolites mono benzyl (MBzP), monobutyl (MBP), monoethyl (MEP), and mono (2ethylhexyl) phthalate (MEHP) were detected in all urinary samples with varying levels. The median concentrations of MBzP, MEHP, MBP, and MEP were 1.4, 54.5, 29.9, and 490 (ng/ml), respectively. In obese children, urinary MBP, MEP, and MEHP demonstrated significantly higher mean levels than in non-obese children. Physical indicators of obesity as body weight, BMI, WC, and HC were significantly positively correlated with urinary levels of MEHP and MEP, while urinary MBzP demonstrated a significant positive association with serum triglycerides levels.

CONCLUSION: The present study suggests an association between phthalates exposure and childhood and adolescent adiposity.

BACKGROUND: Fall-related injuries are identified as a public health problem that has major consequences in affecting the lives of elderly people. Recent studies showed that one out of four elderly people suffers from this condition annually.

AIM: This study aims at identification of fall risk factors that involve intrinsic and extrinsic factor to predict the future fall.

MATERIALS AND METHODS: This study uses an observational design and a descriptive-analytic approach with a cross-sectional method which was used to identify risk factors for falls. This study targeted 60 years and above who live in West Java region. Afterward, a total of 420 people were obtained and divided into two regions, 215 people in Bandung Regency and 205 people in Bandung City. Furthermore, the sampling technique used was for cluster random sampling.

RESULTS: The elderly who experienced incontinence in controlling urination had the potential of falling by 4 times compared to those who did not AOR = 3.73; 95% CI (1.038–13.428). Furthermore, those who had history of falling in the past 12 months were 2.4 times exposed compared to those who had not fallen AOR = 2.438; 95% CI (1.219–4.875). Balance disorders also contributed in increasing the risk of fall by 2 times with a value of AOR = 1.703; 95% CI (1.018–2.849). An extrinsic factor, namely, unsafe home environment has higher possibility to increase the risk of falling 2.6 times compared to those in safer environment (AOR = 2.603; 95% CI [1.331–5.087]).

CONCLUSION: This study succeeded in identifying the risk factors for falls among the elderly in intrinsic and extrinsic approach. This finding can be used as a reference in planning health promotion programs for elderly people, specifically in the primary prevention of morbidity and mortality that occur due to falls.

Nowadays, the treatment for bone damage remains a significant challenge. As a result, the development of bioactive three-dimensional scaffolds for bone regeneration has become a key area of study within tissue engineering. This research is focused on the evaluation of the properties of Chitosan (Ch)/Polycaprolactone (PCL) scaffolds with the Mytilus californiensis protein by Thermally Induced Phase Separation (TIPS). This study used the extrapalleal fluid protein from Mytilus californiensis because it increases biological processes that support bone regeneration. Two methodologies were used for the scaffolds functionalization: (I) an immersion process in a solution with the protein and (II) the protein direct addition during the scaffold synthesis. The scaffolds were analyzed by Fourier Transformed Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), and Mechanical Compression test to determine the composition, morphology, and mechanical properties of each material. In vitro analysis of biodegradation, bioactivity, and biocompatibility were also performed. The scaffolds with the protein added directly presented superior properties in the tests of bioactivity and cellular proliferation, making these composites attractive for the area of bone regeneration.

In recent times, self-driving vehicles have been widely adopted across different countries as they are equipped to drastically reduce the number of road accidents and congestion on the road thereby improving the traffic efficiency. To detect, identify, and label the traffic signs on the road in order to help the Advanced Driver Assistance Systems (ADAS) in these autonomous vehicles with navigation details, a Traffic Sign Recognition (TSR) System using a deep convolutional neural network model, Mask RCNN (Mask Regional Convolutional Neural Network), is proposed in this paper that aims to help the autonomous vehicles comprehend the road ahead and safely navigate to the desired destination. This paper presents the detection and labelling of Indian and European Signs and also the results of the system working efficiently under various challenging visibility conditions. The results obtained show that the Mask RCNN model has recorded higher performance compared to all the other CNN models that have been previously used for traffic sign recognition.

India’s high levels of transport-related air pollution endanger public health. The transition to electric mobility will address this challenge while also reducing the country’s dependence on oil imports. The Government of India has offered incentives to electric vehicle manufacturers and purchasers that promote faster adoption of electric vehicles. The states have framed electric vehicle policies offering additional fiscal and non-fiscal incentives supporting this objective, but the adoption rate of electric vehicles in India is far below expectations. This paper aims to understand the factors that influence the electrification of urban freight vehicles. It does so with reference to urban freight movements linked to textile markets in Ahmedabad and Surat, and the fruit and vegetable market in Delhi.  By studying these, it attempts to assess the impact of key policy and market conditions on the adoption of electric vehicles. Based on stakeholder perceptions, it further tries to identify the enablers and barriers to the electrification of urban freight vehicles.
Studies on the Open-negative Syndrome and Pathological Open Healing
Authors: Chang Pyoung Ha
Published: March 2022

Three cases of pulmonary tuberculosis with formation of cystic cavities and a case of openly and pathologically healed tuberculous cavity are presented. The persistence of a smooth and thin walledcavity in the roentgenogram with the disappearance of tubercle bacilli from the sputum and gastric washings over six months are the criteria for the open-negative syndrome and free of necrotic contents or pyogenic membrane in the lumen of the cavity and transformed cavity wall into a layer of connective tissue are the criteria for the pathological open healing.The choice of whether these cavitary lesions are to be treated surgically or observed on a long-term medical program must be individualized on the merits and status of each case.
Seifert hypersurfaces of 2-knots and Chern–Simons functional
Authors: Taniguchi Masaki
Published: March 2022

For a given smooth 2-knot in

S^4

, we relate the existence of a smooth Seifert hypersurface of a certain class to the existence of irreducible SU(2)-representations of its knot group. For example, we see that any smooth 2-knot having the Poincaré homology 3-sphere as a Seifert hypersurface has at least four irreducible SU(2)-representations of its knot group. This result is false in the topological category. The proof uses a quantitative formulation of instanton Floer homology. Using similar techniques, we also obtain similar results about codimension-1 embeddings of homology 3-spheres into closed definite 4-manifolds and a fixed point type theorem for instanton Floer homology.
Axial Turbine Turbocharger for Charging a Lean-Burn Gasoline Engine

Published: March 2022

A single-stage turbocharger turbine is developed with the objective of enabling a gasoline spark-ignition engine to operate under lean-burn conditions with an air-to-fuel ratio of λ=2 in the range of the Worldwide Harmonized Light-Duty Vehicles Test Cycle. For this purpose, extensive 1-D engine simulations are performed using a combination of a simple compressor and simple turbine model as well as a combination of the stock compressor and a simple turbine model. The results show that an isentropic turbine efficiency of more than 70% over a wide operating range is required for the desired engine operation - especially with regard to the low-end-torque. Based on the crank-angle-resolved engine simulation data, turbine requirements are determined. Their evaluation shows that an axial turbine is a reasonable alternative to conventional radial turbines for this application. Next, a preliminary axial turbine is designed using 1-D/2-D design approaches. Then, the corresponding performance map is calculated by 3-D CFD simulations showing isentropic total-to-static turbine efficiencies of up to 77% over a wide operating range. Ultimately, the derived turbine performance map is implemented into the 1-D engine model and the valve train settings are optimized for this configuration to enhance the lean-burn performance further. The simulation results show a significantly extended λ=2 operating range in comparison to the stock turbine.
Active Learning Optimization for Boundary Identification Using Machine Learning-Assisted Method
Authors: Ryu Joonjae , Wei Yifan
Published: March 2022

Identifying edge cases for designed algorithms is critical for functional safety in autonomous driving deployment. In order to find the feasible boundary of designed algorithms, simulations are heavily used. However, simulations for autonomous driving validation are expensive due to the requirement of visual rendering, physical simulation, and AI agents. In this case, common sampling techniques, such as Monte Carlo Sampling, become computationally expensive due to their sample inefficiency. To improve sample efficiency and minimize the number of simulations, we propose a tailored active learning approach combining the Support Vector Machine (SVM) and the Gaussian Process Regressor (GPR). The SVM learns the feasible boundary iteratively with a new sampling point via active learning. Active Learning is achieved by using the information of the decision boundary of the current SVM and the uncertainty metric calculated by the GPR. The optimal sampling point is selected through multi-objective optimization so that the sampling point is close to the decision boundary of the current SVM as well as it has a high uncertainty metric. To illustrate the characteristics and effectiveness of the proposed approach, we apply the proposed approach to both simple problems with synthetic feasible regions and a complex industrial problem: autonomous driving path planning algorithm validation. With the proposed approach, edge cases are more effectively identified, so the classification accuracy of the resulting SVM is considerably higher than that of the SVM trained with conventional sampling techniques such as Monte Carlo Sampling and Latin Hypercube Sampling.
