Trilateral Location based Maximum Weighted Directive Spanning Tree for Optimal Routing in IoV
Authors: Suguna Devi S. , Bhuvaneswari A.
Published: January 2022

Internet of Vehicles (IoV) is one of the developing models in the Vehicular adhoc networks (VANETs) with the vast improvement of communication technologies. In order to improve data transmission among the multiple communities without link breakage, a novel Trilateral Location Identified Maximum Weighted Directive Spanning Tree (TLIMWDST) technique is introduced. The proposed TLIMWDST technique consists of two major phases, namely location identification and optimal path identification to improve the reliability of data transmission from source vehicle to destination vehicle. In the first phase, the location of the neighboring vehicles is identified by applying a trilateration technique.  After the location identification, an optimal route path between the source and destination is identified using Maximum Weighted Directive Spanning Tree (MWDST) through the intermediate nodes. The performance of the TLIMWDST technique is assessed through simulation  as compared to the previous path selection techniques in terms of different routing metrics such as packet delivery ratio, packet loss rate, end-to-end delay and throughput with respect to the number of data packets.

Published: January 2022

Natural language processing plays a great role in providing an interface for human-computer communication. It enables people to talk with the computer in their formal language rather than machine language. This study aims at presenting a Part of speech tagger that can assign word class to words in a given paragraph sentence. Some of the researchers developed parts of speech taggers for different languages such as English Amharic, Afan Oromo, Tigrigna, etc. On the other hand, many other languages do not have POS taggers like Shekki’noono language.  POS tagger is incorporated in most natural language processing tools like machine translation, information extraction as a basic component. So, it is compulsory to develop a part of speech tagger for languages then it is possible to work with an advanced natural language application. Because those applications enhance machine to machine, machine to human, and human to human communications. Although, one language POS tagger cannot be directly applied for other languages POS tagger. With the purpose for developing the Shekki’noono POS tagger, we have used the stochastic Hidden Markov Model. For the study, we have used 1500 sentences collected from different sources such as newspapers (which includes social, economic, and political aspects), modules, textbooks, Radio Programs, and bulletins.  The collected sentences are labeled by language experts with their appropriate parts of speech for each word.  With the experiments carried out, the part of speech tagger is trained on the training sets using Hidden Markov model. As experiments showed, HMM based POS tagging has achieved 92.77 % accuracy for Shekki’noono. And the POS tagger model is compared with the previous experiments in related works using HMM. As a future work, the proposed approaches can be utilized to perform an evaluation on a larger corpus.
Analysis of Factors Affecting Density of Vaccine Centers by Fuzzy ELECTRE I Method
Authors: TÜMAY ATEŞ Kübra
Published: January 2022

Nowadays, the increase in vaccinations due to the epidemic increases the density of health centers and shopping centers, which is another place where vaccinations are made, from time to time. The choice of vaccination sites varies from person to person, and this may increase the density of the vaccination sequence. The criteria that cause the increase in density were created by consulting the health personnel, the people who will be vaccinated and those who have had the vaccine, taking into account the conditions and situations that people care about. Alternatively, three different vaccine centers were selected. These centers are designated as hospitals, health centers and shopping centers. Care has been taken to ensure that the designated vaccination centers are places where daily vaccinations are performed. In order to determine the criteria, the opinions of the people were taken by applying a questionnaire. Thus, in this study, which was conducted for the first time, it was investigated which places were more dense with the determined nine criteria and the parameters affecting this density were tried to be analyzed with the Fuzzy ELECTRE I method. Knowing the reasons for these densities and revealing which institutions people frequently prefer for vaccination can prevent problems.

Authors: TAŞKAYA Selim
Published: January 2022

Zoning plans are the design work required for the correct use of space in terms of urbanization. While creating zoning plans, zoning islands are created together with various planning methods. Reconstruction islands are also named as having legends such as residence, subject + commercial, commercial, social areas, religious facility areas called places of worship, green areas. The important part is how the construction permit is given to the parcels that will coincide within these islands. This process is the zoning diameter. Zoning diameters are the drawings made on the ground according to different methods. In our study of how to give zoning diameters to different types of zoning islands, it was aimed to provide appropriate angle distances inside perpendicular or parallel by adding the lengths of the parcels to each other, which we call the sine theorem. It was examined how the zoning island would be given a diameter in terms of length according to the precedent and the amount of height processed in the plan.

Authors: ARSLAN Onur
Published: January 2022

Hydrological drought refers to the decrease in the amount of water found in surface or groundwater resources and monitoring of this natural disaster is very important due to causing serious problems in drinking and irrigation water supply and hydroelectric energy production. In this study, hydrological drought analysis was made for two streams in Bolu city located in the Western Black Sea Region in the north of Turkey and 3, 6 and 12 month streamflow drought indices were calculated by using the Streamflow Drought Index method. For this aim, the streamflow data of Bolu stream - Beşdeğirmen and Ulusu - Afatlar streamflow monitoring stations were used. According to the results, extreme and severedroughts were determined for two stream flow stations and it is seen that drought periods varied between 1 and 9 years. The most severe and longest droughts were detected for Bolu stream - Beşdeğirmen station. Mild droughts are much higher than moderate, severe and extreme droughts. It has been observed that the severity and number of drought for Bolu stream - Beşdeğirmen station have increased in recent years. In order to reduce the effects of hydrological drought, hydrological drought should be monitored continuously and necessary precautions should be taken regarding the management of water resources. People should be informed about water consumption and so waste should be prevented. Interms of irrigation water, drip irrigation method should be used instead of flood irrigation or sprinkler irrigation methods. For this aim, farmers should be made aware of this issue. Alternative renewable energy sources or other energy sources should be used for reductions in hydroelectric energy production.

Blended Learning sebagai Model Pembelajaran Abad 21
Authors: Puspitarini Dyah
Published: January 2022

Tulisan ini bertujuan mendeskripsikan perkembangan paradigma pembelajaran, konsep pembelajaran berbasis teknologi, dan penerapan blended learning sebagai model pembelajaran abad 21. Proses pembelajaran tak luput dari sentuhan teknologi, khususnya yang berbasis internet. Peserta didik saat ini merupakan generasi milenial dan generasi Z yang sangat akrab dengan teknologi informasi dan komunikasi. Oleh karena itu guru harus mampu menyesuaikan diri dengan karakteristik peserta didik milenial, sehingga tidak bisa lagi mengajar dengan strategi pembelajaran yang standar dan biasa-biasa saja. Guru harus kreatif, mengembangkan beragam strategi, metode, dan model pembelajaran untuk menyajikan kegiatan pembelajaran yang menarik, juga harus mampu memanfaatkan e-learning sebagai alternatif pembelajaran. Namun, baik pembelajaran tatap muka maupun e-learning masing-masing memiliki kelemahan. Blended learning yang memadukan kelebihan pembelajaran tatap muka dan e-learning merupakan pilihan yang tepat. Dalam pembelajaran blended, guru memanfaatkan teknologi informasi dan komunikasi, tetapi tetap dapat ‘bersentuhan’ dengan peserta didik melalui pembelajaran tatap muka.  Blended learning mengombinasikan beberapa strategi pembelajaran yaitu kegiatan tatap muka, pembelajaran berbasis komputer secara offline, dan komputer secara online. Blended learning dapat diterapkan tanpa batasan khusus berapa prosentasi tatap muka dan penggunaan teknologi komputer atau internet, dilakukan secara sinkronius atau asinkronius. Dalam merancang desain pembelajaran guru dapat menentukan prosentase pemanfaatan internet baik secara online maupun offline. Hasil dari proses pembelajaran blended learning efektif karena mampu mengatasi kelemahan model pembelajaran tatap muka yang didominasi guru, sekaligus kelemahan pembelajaran secara e-learning yang hanya mengandalkan teknologi komunikasi.

Zihnin doğasına ilişkin gizem, geçmişten günümüze felsefi soruşturmaların baş konusu olma niteliğini korumaktadır. Söz konusu gizemi gidermek için ortaya atılan kuramlar, kabaca, zihnin gayri maddi ve bedenin maddi olmak üzere iki farklı töz olduğunu ifade eden düalist görüş ile sadece maddenin (materyalizm) ya da sadece zihnin (idealizm) tek töz olarak var olduğunu iddia eden monist görüşler şeklinde sınıflandırılabilir. Bu makale, Gazzâli’nin bir kelamcı olarak ruha dair görüşlerini sistematik bir bütünlük içinde vermeyi ve Gazzâli’nin bu konudaki pozisyonunu ortaya koymayı birincil hedef edinmektedir. Bu amacı gerçekleştirmek için makale, önce ruhla ilgili var olan tanımları irdelemekte, sonra Gazzâli’nin ruh ve ruhla bağlantılı akıl, kalp, nefs gibi unsurları nasıl tanımladığını ve bu tanımların sonuçlarının meydana getirdiği problematiği masaya yatırmaktadır. Son olarak makale, Gazzâli’nin ruhun mahiyetine dair düalist bilinemezci/gizemci bir noktada konumlandığını iddia etmektedir.
RELATIONSHIP BETWEEN PRODUCTIVITY AND DIGITALIZATION WITH TOBIT MODEL BASED ON MALMQUIST INDEX
Authors: BOZKURT Eda , TOPÇUOĞLU Özlem , ALTINER Ali
Published: January 2022

Purpose: The sources of economic growth include capital, labor and the Solow surplus, dedicated to the study of Solow (1956). Solow surplus is the inexplicable part of growth with labor and capital and is expressed as technological advances. Solow surplus also means total factor productivity (TFP). In other words, economic growth is explained by TFP depending on technology from the past to the present. These days, digitalization is known to be the new technological revolution. In light of this concept, the study aims to demonstrate the impact of digitalization on TFP. Methodology: A TFP calculation based on the Malmquist index was made using labor, capital and gross domestic product data for 30 countries in the period 2012-2020. The Tobit Panel estimate was then used to determine the effect of digitalization on TFP in the relevant period. Findings: the results of the panel estimate are that digitalization has a significant and positive impact on TFP. The findings suggest that digitalization contributes to productivity. Originality: The most important feature that distinguishes research from studies in the literature is that a verification method is selected that uses real data. In addition, works covering many countries in literature is limited. The research has results from a multi-country perspective.
Testing the efficacy of atmospheric boundary layer height detection algorithms using uncrewed aircraft system data from MOSAiC

Published: January 2022

Abstract. During the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition, meteorological conditions over the lowest 1 km of the atmosphere were sampled with the DataHawk2 (DH2) fixed wing uncrewed aircraft system (UAS). Of particular interest is the atmospheric boundary layer (ABL) height, as ABL structure can be closely coupled to cloud properties, surface fluxes, and the atmospheric radiation budget. The high temporal resolution of the UAS observations allows us to subjectively identify ABL height for 65 out of the total 89 flights conducted over the central Arctic Ocean between 23 March and 26 July 2020 by visually analyzing profiles of virtual potential temperature, humidity, and bulk Richardson number. Comparing this subjective ABL height with the ABL heights identified by various previously published objective methods allows us to determine which objective methods are most successful at accurately identifying ABL height in the central Arctic environment. The objective methods we use are the Liu-Liang, Heffter, virtual potential temperature gradient maximum, and bulk Richardson number methods. In the process of testing these objective methods on the DH2 data, numerical thresholds were adapted to work best for the UAS-based sampling. To determine if conclusions are robust across different measurement platforms, the subjective and objective ABL height determination processes were repeated using the radiosonde profile closest in time to each DH2 flight. For both the DH2 and radiosonde data, it is determined that the bulk Richardson number method is the most successful at identifying ABL height, while the Liu-Liang method is least successful.
A two-parameter model for the determination of the partition coefficient for TRS in a culture medium
Authors: Silva Javier , Ortiz Rodrigo , Carrasco Samuel , Aroca German
Published: January 2022

A two-parameters model was applied for the determination of the activity coefficient for a culture medium, and compared with Henry's law, the extended UNIQUAC, and experimental data obtained from an experimental setup system, consisting of a liquid culture media Thiobacillus (ATCC 290) with hydrogen sulfide (H2S), dimethyl sulfide (DMS), methyl mercaptan (MM), and dimethyl disulfide (DMDS), respectively.
 The ANOVA indicates that the use of Henry's law is not appropriate for MM and H2S with R2adj values of -106.15% and -53.33%, respectively. The extended UNIQUAC model and the two-parameter model were able to describe the system with values of 76.94% and 94.15% for DMS and DMDS in the case of UNIQUAC Extended, respectively, and 88.50% and 98.08% using the two-parameter model.
 
These results show that the two-parameter model is able to describe the system, using a low number of parameters. However, the extended UNIQUAC shows better results but presenting a high level of over-parameterization. Henry's law showed significant deviations, not being representative of all analyzed cases.
 The two-parameter model is presented as an alternative to describing systems in which vapor-liquid mass transfer is involved in culture media, providing a better approximation than traditional models and lower calculation costs than complex models.

Published: January 2022

In this study, resistant starch (RS)-enriched pudding production was performed in order to develop puddings with reduced glycemic index which could be consumed as functional milky dessert to cope with obesity and high blood sugar. Control sample without the resistant starch (RS) and three pudding samples with RS (1%, 2% and 3%) were prepared. Physical analyzes of the samples were performed, their sensory and rheological properties were examined and glycemic index analyzes were implemented in vitro conditions.  With the addition of RS, the moisture content of the puddings decreased and there was an increase in L* value. The rheological properties of pudding samples were evaluated using a rheometer. Results showed that, the viscosities of the RS added samples were lower when compared to to the control sample. The glycemic index value decreased with the increase in the RS content of puddings. Sensory analysis test was performed to a group consisting of 10 panelists. 3% RS sample was determined to be more favorable. Analyzes showed that RS caused positive effects on pudding moisture, brightness, rheology and glycemic index. As a result of this study, it was found that the sample containing 3% RS had acceptable and favorable properties.

Methodology: One hundred female patients with androgenic alopecia of all ages after puberty were included. Patients with scarring and other non-scarring alopecia, who had taken iron, vitamin B12, folic acid or multivitamin supplements, anticoagulants, anti-thyroid drugs, antimitotic drugs and oral contraceptives were excluded. After aseptic measures,5 ml of venous blood was drawn, into sterile and disposable plastic syringes. Serum ferritin was measured by enzyme immunoassay (EIA) test, based on sandwich ELISA. Results: Mean age was 33.94±6.29 years and 65 (65.0%) of patients ranged from 36 to 50 years. Average duration of disease was 6.25±2.43 months. Mean weight was 58.77±9.17 kg. Mean serum ferritin levels in female patients with androgenetic alopecia was 33.10±42.99ng/ml. Conclusion: Serum ferritin levels in female patients with androgenetic alopecia are low. Keywords: Androgenic alopecia, Serum ferritin levels
An Infeasible Interior-point Algorithm for Monotone Linear Complementarity Problems
Authors: GRİMES Welid , ACHACHE Mohamed
Published: January 2022

In this study, we implement a variant of infeasible interior-point algorithm for solving monotone linear complementarity problems (LCP). We first reformulate the monotone LCP as an minimization problem. Then a descent iterative method is applied to the latter. The descent direction is computed via the Newton method. However, for maintaining the positivity of iterates, a novel and efficient strategy is proposed. Some numerical results are reported to show the efficiency of our proposed approach.

O direito à saúde é considerado universal, resultante de uma grande mobilização política da sociedade.  Historicamente a população LGBT sofre preconceitos e têm seus direitos fundamentais violados. Devido a esse fator, o acesso dessa população aos serviços de saúde se torna fraco e sensível, contribuindo para uma piora no estado de saúde do indivíduo. Este estudo se justifica no entendimento de que é necessário que haja o desenvolvimento de ações e estratégias de saúde que possam promover a integralidade, a equidade e a universalidade da atenção à saúde da pessoa LGBT. O objetivo geral desse estudo é descrever as ações e estratégias de saúde para o atendimento específico das pessoas LGBT, com foco na multidisciplinaridade. Trata-se de uma pesquisa descritiva, transversal com abordagem qualitativa, que foi realizada com graduandos dos cursos da área da saúde de uma instituição de ensino superior (IES) situada em um município da grande São Paulo. Embora tenha sido perceptível que a ausência da abordagem dessa temática nos cursos de enfermagem, nutrição, fisioterapia e psicologia, os graduandos descreveram ações e estratégias para a atenção à saúde da população LGBT, levando em consideração os preceitos dos direitos humanos, a integralidade, equidade e universalidade, no campo de suas áreas de conhecimento e da multidisciplinaridade.

Published: January 2022

This study was designed to assess the knowledge, attitude, and practices of Nigerian optometrists and optometry students with regard to the COVID-19 pandemic, while also assessing its impact of their daily personal and professional routines. The Google Forms suite was used to design an online struc- tured survey/questionnaire. This was sent to Nigerian optometrists and optometry students along with a message soliciting their voluntary participation. This survey took place between 10th April and 15th May 2020. The responses received were electronically transmitted to the authors and populated via Google suite software. Descriptive statistics and inferences were then derived from these data. A total of 399 valid responses were logged during this study. Of these, 183 (45.4%) respondents were optometry students from the eight optometry education departments in Nigeria. Optometric doctors made up 216 of the respondents. 86% of optometrists reported having cases of COVID-19 in their state. No optometrists reported suffering from the COVID-19 disease while one (0.5%) student had been infected with COVID-19. Twelve percent of student respondents felt educational facilities were adequate to cater for post COVID- 19 resumption, while 21.5% of students felt that the ongoing academic session should be restarted. The COVID-19 Pandemic has impacted greatly on service delivery among Nigerian optometrists and optometry education. Educational institutions must also adjust to current realities in order to be able to provide safe and adequate training when the academic section resumes or restarts.
Botulinum toxin treatment for adductor spasmodic dysphonia with EMG and endoscopic guidance
Authors: Nguyen Thanh Tuan , Tran Ngoc Tai , Nguyen Truc Dung , Nguyen Thi Hung
Published: January 2022

Background & Objective: Spasmodic dysphonia is idiopathic focal dystonia characterized by irregular contractions or postural disorders of the laryngeal muscles, resulting in abnormal speech. Progress in laryngoscopy has resulted in development of a precise technique of botulinum toxin (BTX) injection into the thyroarytenoid muscle under visual control.
Methods: We used EMG and endoscopic guidance for BTX injection in adductor spasmodic dysphonia (AdSD).
Results: Thirty eight patients with AdSD were injected with BTX in 84 treatment sessions. The voice handicap index (VHI) level of the patients were: severe (73.8%), moderate (26.2%) and mild (none). The average VHI score was 74.6 points. After 8 weeks of BTX treatment, the VHI level was: Severe (3.6%), moderate (10.8%), and mild (85.7%). The average VHI score was 27.7 points. The average values of jitter, shimmer and harmonic to noice ratio (HNR) improved statistically (p < 0.05). The incidence of side effects were: breathiness (17.9%), choking (15.5%); hoarseness (8.5%), and dysphagia (4.7%).
Conclusions: Injection of BTX under both EMG and laryngoscopy guidance for treatment of adductor spasmodic dysphonia is an effective and safe treatment.
Can immature granulocytes indicate mortality in patients with acute ischemic stroke?
Authors: Korkut Mustafa , Bedel Cihan , Zortuk Ökkeş , Selvi Fatih
Published: January 2022

Background & Objective: Stroke is the most common cause of permanent disability and the most important cause of mortality. Acute ischemic stroke (AIS) reveals inflammation in the ischemic brain tissue. Ischemic tissue causes proinflammatory cytokine release and aggregation of immune cells. Therefore in this study, we aimed to investigate the role of immature granulocyte (IG) in showing 30-day mortality in patients with AİS.
Methods: This study was designed as a single-centered, retrospective cohort study. Patients aged >18 years who were diagnosed with AIS in the tertiary emergency department were included in this study. Patients were divided into two groups as low (<0.6%) and high (≥0.6%) by IG values. Demographic and laboratory parameters were compared between the groups at admission to the emergency department.
Results: Our study consisted of 172 patients diagnosed with AIS, who met the inclusion criteria. The average age of the study group was 69.19 ± 14.34 years, and 94 (54.7%) of the patients were male. 98 (56.9%) patients were in the low IG group, and 74 (43.1%) of them were in the poor outcome group. IG at the cut-off value of 1.3 was shown to predict mortality in patients with AIS with 80.5% sensitivity and 93.2% specificity (area under the curve: 0.715 95% CI: 0.623-0.807, p <0.001)
Conclusion: The results of our study showed that IG is a new and simple predictor to predict 30-day prognosis in patients with AIS.
Brachial Plexopathy from Metaldehyde Poisoning – A Case Report
Authors: Tan See-Teng , Chen Guanglin , Lee Wai Ching, Deanna , Tan You-Jiang
Published: January 2022

We describe the case of a middle-aged female with schizophrenia, who developed acute sensorimotor deficits of the right upper limb within a week of ingesting large amounts of metaldehyde in a suicide attempt. A right-sided brachial plexopathy was diagnosed clinically and supported by electrophysiologic assessments and targeted magnetic resonance imaging scans. Although metaldehyde’s neurotoxicity typically affects the central nervous system, focal involvement of the peripheral nervous system remains unreported in medical literature, and its pathogenic processes await further elucidation. Therefore, we recommend the continued observation for the subsequent development of sensorimotor deficits during the first week of metaldehyde poisoning.
Variability of Indian summer monsoon: Relationship with surface air temperature anomalies over northern hemisphere
Authors: VERMA R. K.
Published: January 2022

Thirty year (1950-79) time series of Monsoon Index (MI) is correlated with the gridded surface air temperature data over northern hemisphere land at various time lags of months (i.e., months preceding concurrent and succeeding to the monsoon season) to identify tele-connections of monsoon with the northern hemisphere surface air temperature anomalies. .

 

Out of three key regions identified which show statistically significant relationship of monsoon rainfall, two regions are in the higher latitudinal belt of 40oN- 70oN over North America and Eurasia which show positive correlations with temperatures during northern winter particularly during  January and February. The third region is located over northwest India and adjoining Pakistan, where the maximum positive correlation is observed to occur during the pre-li1onsoon months of April and May. These relationships suggest that cooler northern hemisphere during the preceding seasons of winter/spring over certain key regions are generally associated with below normal summer monsoon rainfall over India and vice-versa which could be useful predictors for long-range forecasting of monsoon.

 

There are two large regions in the northern tropics, namely, Asian and African monsoons whose temperatures reveal strong negative correlations with monsoon rainfall during the seasons concurrent and subsequent to the summer monsoon season. However, persistence of this relationship for longer period of about two seasons after the monsoon, suggests the dominant influence of  ENSO (El. Nino-Southern Oscillation) on tropical climate.
Daily rainfall persistence over Sri Lanka
Authors: DOMRQES MANFRED , RANATUNGE EDMOUND
Published: January 2022

The spatial distribution of daily rainfall persistence is examined adopting Besson's persistence coefficient and using daily rainfall data for 15 consecutive years (1971-1985). The daily rainfall persistence coefficients have been studied separately for all the twelve months individually and for the whole year. Where January and February indicate the lowest rainfall persistence coefficients the period from October to December indicates the highest coefficients over Sri Lanka. Besides the monsoonal atmospheric conditions, the topography has a strong influence on the rainfall persistence distribution over space and time. The daily rainfall persistence coefficients record higher values in the wet zone then in the dry zone of Sri Lanka. Regression analysis shows a better linear relationship between mean length of wet spell~ and the daily rainfall persistence coefficients and the resultant final equation is y.4' =0.1093+0.1600+X M having the correlation coefficient of 0.721 which is significant at the 0.01% level.
