Published: August 2022

BackgroundThe rise in data analytics has resulted in the need for data to be pooled into centralized large-scale repositories to support more organized analytics. In the health sector, housing health data in a central analytic repository makes it easier for policymakers to access and make faster, more efficient informed decisions that impact the population, especially in cases of emergencies and disease outbreaks. Our study aimed to develop a centralized health data analytics repository for Nigeria called the Multi-Source Data Analytics and Triangulation (MSDAT) platform to improve decision-making by stakeholders.MethodsThe MSDAT design and development was a data and user-centred process guided and informed by the perspectives and requirements of analysts and stakeholders from the Federal Ministry of Health, Nigeria. The inclusion of health indicators and data sources on the platform was based on: (1) national relevance (2) global health interest (3) availability of datasets and (4) specific requests from stakeholders. The first version of the platform was developed and iteratively revised based on stakeholder feedback.ResultsWe developed the MSDAT for the purpose of consolidating health-related data from various data sources. It has 4 interactive sections for; (1) indicator comparison across routine and non-routine data sources (2) indicator comparison across states and local government areas (3) geopolitical zonal analysis of indicators (4) multi-indicator comparisons across states.ConclusionThe MSDAT is a revolutionary platform essential to the improvement of health data quality. By transparently visualizing data and trends across multiple sources, data quality and use are brought to focus to reduce variations between different data sources over time and improve the overall understanding of key trends and progress within the health sector. Hence, the platform should be fully adopted and utilized at all levels of governance. It should also be expanded to accommodate other data sources and indicators that cut across all health system areas.

Published: August 2022

BackgroundThe Japanese guidelines for the management of hip fractures were most recently revised in 2021 to recommend the use of cemented stems in cases of bone fragility. However, the selection of cementless or cemented stem fixations remains controversial. This study aimed to examine the current stem selection strategy in bipolar hemiarthroplasty, concerns about using cemented stems, and factors affecting the ability to instruct cemented stems.MethodsThis study included 94 orthopedic surgeons from 27 facilities who answered a web-based questionnaire survey of 15 questions in the super-aging prefectural area in Japan from January to February 2022. Multiple logistic regression analysis was used to identify the factors associated with the ability to instruct the cemented stem. The cutoff value for the number of cemented stem usage experiences that can be used to instruct cemented stems was determined using the receiver operating characteristic (ROC) curve.ResultsA total of 97.8% of doctors answered that the cementless stem was the current first choice, and 83.0% of doctors had only 0–10 cases of the cemented stem. Meanwhile, only 14.9% of doctors are expected to increase the use of cemented stems in the future. The cement technique was the greatest concern regarding the use of cement stems (60.6%). On multivariate analysis, the number of surgeries of the cemented stem was the factor most affecting the ability to instruct the cemented stem (odds ratio: 8.42, p=0.001). In the ROC curve analysis for the capability of instructing cemented stems and the number of surgeries using cemented stems, the best cutoff value was 1–10 cases (sensitivity, 94.4%; specificity, 58.6%), with an area under the curve of 0.8448 (95% confidence interval: 0.7754–0.9142). When the cut-off value was 11–50 cases, the specificity was higher (sensitivity, 41.7%; specificity, 98.3%).ConclusionsA few doctors still select cemented stems as the first choice. The number of surgeries on the cemented stem was the factor most affecting the ability to instruct the cemented stem, and more than 11 cases are desirable.
Health-Related Quality of Life scores among low-income patients on Social Welfare Programs in Japan: A repeated cross-sectional study
Authors: Wakata Satoshi , Nishioka Daisuke , Takaki Yukio
Published: August 2022

Background: Low-income is one of the well-established determinants of people’s health and health-related behavior including susceptibility to coronavirus disease 2019 (COVID-19) infection. To support financial access to medical care among low-income patients, there are two social welfare services in Japan: Public Assistance (PA) which provide both minimum income and medical costs, and Free/Low-Cost Medical Care (FLCMC) in which only medical costs were covered. The purpose of this study was to describe and compare the changes in Health-Related Quality of Life (HRQOL) scores before and after the COVID-19 pandemic among low-income patients on PA, FLCMC, and the general population, to examine if the social welfare services contributed to protect low-income people’s HRQOL during the pandemic.Methods: We used repeated cross-sectional data obtained from adult patients on FLCMC or PA and those without social welfare services who regularly visit the Kamigyo clinic in Kyoto, Japan. We collected the data from 2018 and 2021 using a questionnaire about patients’ socioeconomic attributes and Medical Outcomes Study 12-Item Short Form Health Survey (SF-12).Results: We analyzed data of 200 individuals in 2018 and 174 individuals in 2021. Low-income patients on social welfare services had lower physical health component summary (PCS) score, and the role-social component summary (RCS) score than general population in each year. The results of multiple linear regression analyses with robust standard estimator showed that the decline in Mental Component Summary (MCS) score was significantly larger among FLCMC recipients than patients without welfare services (coefficient: -4.71, 95% Confidence Interval: -8.92 to -0.51), while the decline in MCS scores among PA recipients were not significant when compared to the general population.Conclusions: Low-income patients on social welfare services especially on FLCMC experienced the significant decline in MCS scores during COVID-19 pandemic. To maintain mental health of low-income patients on social welfare services in the pandemic, need to be provided with not only social care, but financial livelihood support may also be required.Trial registration: N/A

Constructing high-density tissue microarrays with a novel method and a self-made tissue-arraying instrument
Authors: Qin Ping , Zhao Li , Bian Piaopiao , Xiong Zhongtang
Published: August 2022

Tissue microarrays (TMAs), also called tissue chips, contain hundreds to thousands of tissue cores obtained from different tissue donor blocks. By using TMA technology, a molecular marker, such as protein, RAN or DNA, can be simultaneously examined in hundreds of different specimens under the same experimental conditions. A growing number of previous studies have introduced different methods for constructing TMAs. Many authors tried to use various methods to implant more tissue cores in a single recipient block, and most of these methods involved reducing the diameter of the tissue cores and/or the spacing between adjacent tissue cores. However, when creating TMAs, it is difficult to reduce the distance between tissue cores to zero except with extremely expensive automatic TMA arrayers. Here, we introduce a novel method to construct a high-density TMA that does not have spacing between the tissue cores. We also introduce a method for preparing a self-made tissue‑arraying instrument. With this method and the tissue‑arraying instrument, we successfully created a TMA containing 126 tissue cores that were 2 mm in diameter. H&E staining, immunohistochemical staining and fluorescence in situ hybridization were performed on the sections cut from the TMA without any tissue spot loss. This method is easy to operate, and the materials for creating the tissue‑arraying instrument are inexpensive and can be purchased anywhere. Therefore, this high-density method can be applied in all laboratories.

Published: August 2022

The primate amygdala is a complex consisting of over a dozen nuclei, each with distinct connectivity patterns that have been implicated in a host of cognitive functions, individual differences, and psychiatric illnesses. The most robust functional distinction in humans is between medial and lateral nuclei, but connectivity profiles of these subdivisions are based primarily on correlations observed in blood oxygenation-level dependent functional MRI (BOLD-fMRI), limiting spatiotemporal resolution and causal conclusions. Here we conducted concurrent focal bipolar electrical stimulation through depth electrodes with intracranial electroencephalography (electrical stimulation tract-tracing; es-TT), and with fMRI (electrical stimulation fMRI; es-fMRI) in 25 neurosurgical patients (13 es-TT, 16 es-fMRI).

es-TT (51 sessions recorded over 3000 intracranial electrodes) produced profiles of effective connectivity with characteristic latencies of 15 ms (N/P15) and 150 ms (P150) that distinguished medial from lateral amygdala. Whereas lateral stimulation induced greater N/P15 potentials in anterior cingulate, sensorimotor cortex, superior temporal sulcus (STS) and superior parietal lobe (SPL), medial amygdala stimulation produced greater N150 responses in orbitofrontal cortex (OFC), superior temporal gyrus (STG), middle temporal gyrus (MTG) and prefrontal cortex (PFC). es-fMRI confirmed a similar spatial segregation of responses. Orbitofrontal cortex and anterior cingulate cortex were the key components of an amygdala network and received rapid signal propagation from the amygdala, which then continued to PFC and lateral temporal lobe, before reaching to sensorimotor and parietal cortices. Second-order effects of stimulation engaged network over broad areas of cortex, further distinguishing the site of amygdala stimulation. The findings provide a uniquely detailed characterization of human amygdala functional connectivity that will inform functional neuroimaging studies in healthy and clinical populations.
The study of the effect of item parameter drift on ability estimation obtained from adaptive testing under different conditions
Authors: ŞAHİN KÜRŞAD Merve , ÇOKLUK-BÖKEOGLU Ömay , ÇIKRIKÇI Nükhet
Published: August 2022

Item parameter drift (IPD) is the systematic differentiation of parameter values of items over time due to various reasons. If it occurs in computer adaptive tests (CAT), it causes errors in the estimation of item and ability parameters. Identification of the underlying conditions of this situation in CAT is important for estimating item and ability parameters with minimum error. This study examines the measurement precision of IPD and its impacts on the test information function (TIF) in CAT administrations. This simulation study compares sample size (1000, 5000), IPD size (0.00 logit, 0.50 logit, 0.75 logit, 1.00 logit), percentage of items containing IPD (0%, 5%, 10%, 20%), three time points and item bank size (200, 500, 1000) conditions. To examine the impacts of the conditions on ability estimations; measurement precision, and TIF values were calculated, and factorial analysis of variance (ANOVA) for independent samples was carried out to examine whether there were any differences between estimations in terms of these factors. The study found that an increase in the number of measurements using item bank with IPD items results in a decrease in measurement precision and the amount of information the test provides. Factorial ANOVA for independent samples revealed that measurements precision and TIF differences are mostly statistically significant. Although all IPD conditions negatively affect measurement precision and TIF, it has been shown that sample size and item bank size generally do not have an increasing or decreasing effect on these factors.

Por uma política externa baseada em evidência
Authors: Schettino Valente Mario , Belém Lopes Dawisson
Published: August 2022

Uma das maiores deficiências da Análise de Política Externa é escassez de estudos sobre os resultados. Soma-se, ainda, o entendimento, no Brasil, de que a política externa, ainda que seja uma política pública, conservaria características de política de Estado. Essa noção não aporta benefícios heurísticos, por não representar a dinâmica política, e obstaculiza a produção da política externa a partir de evidência. Este artigo, via revisões bibliográficas, contribui para o campo em duas frentes: apresentando um conceito de política pública que abarca integralmente a política externa, e debatendo os principais modelos e a validade da avaliação como abordagem de pesquisa.

Authors: ŞAHİN Kasım
Published: August 2022

Kayseri ili, Türkiye’de şeker pancarı üretiminin yapıldığı önemli iller arasında yer alır. Şeker pancarı, ülkemizde stratejik öneme sahip bir üründür. Tarıma dayalı sanayi için de hammadde sağlamaktadır. Şeker pancarı tarımının diğer sektörlere olan katkısı da düşünüldüğünde sürdürülebilirliğinin sağlanması büyük bir önem taşımaktadır. Bu araştırmada, Kota uygulamalarının Kayseri ili Sarıoğlan ilçesi şekerpancarı üretimine olan etkileri belirlenmeye çalışılmıştır. Bu araştırmada Olasılığa Dayalı Örnekleme metodu kullanılmıştır. Bu amaçla 156 üretici ile yüz yüze anket görüşme yoluyla veriler toplanmıştır. İlçede işletme başına ortalama şeker pancarı üretim alanı 44.92 dekardır. Araştırma da çiftçi başına ortalama kota miktarı 233.83 tondur. Çiftçilerin %71,8’si şekerpancarı kota uygulamasında kota miktarının düşük olduğunu belirtmişlerdir. C kotası uygulamasındaki fiyat düşüklüğünün sorun olarak belirtenlerin oranı ise % 92.3 tür. Üreticiler örtülü olarak kota sistemini destekler niteliktedir. Bu durumun, sulu tarım alanlarında şekerpancarı üretebilecek kişilerin üretim yapmasını zorlaştırdığı görülmüştür. Şeker pancarı üretimi ve devamı ettirilme konusunda üreticilerin farklı görüşlere sahiptir. Üretim olumsuz etkileyen ve destekleyen en etkili faktörler ise kuraklık ile birlikte daha çok sulama gereksinimi olması ve şeker pancarına alternatif olarak yetiştirilen ürünlerin de su isteği çok olan bitkiler olmasıdır.

Published: August 2022

With the increase of e-commerce volumes in recent years, it is useful to estimate daily demand order numbers in order to improve the demand forecasts, production-distribution planning and sales services. In this manner, data-driven modeling and machine learning tools have been preferred to enhance demand order predictions, timely delivery, incomes and customer satisfaction in electronic trading because real-time data collection is possible in e-commerce platforms. Artificial Neural Networks (ANNs) are widely used for data-driven modeling and prediction problems. Since affecting the approximation performance of neural network function, the modeling performance of ANNs strongly depends on the architecture of neural networks, and architectural optimization of ANN models has become a main topic in the neuroevolution field. This study presents an architecture optimization method that implements Particle Swarm Optimization (PSO) and Differential Evolution (DE) algorithms to optimize ANN model architecture for the estimation of total demand order numbers from the sparse demand order data. In this approach, PSO and DE algorithm only optimizes neural model architecture according to an effective network search policy and the training of ANN models is carried out by using backpropagation algorithm. This neural architecture model optimization approach considers generalization of data, reducing neuron and training epoch numbers and it can yield an optimal architecture data-driven neural model for estimation of the daily total orders. In the experimental study, optimal architecture ANN models are obtained according to the daily order forecasting dataset.

Published: August 2022

Bu çalışmada binaların doğal havalandırılmasında önemli bir rol oynayan pencerelerin şekli, boyutu ve
hakim rüzgar yönüne göre konumunun binaların havalandırılmasındaki rolü incelenmiştir. Sabit hızda hava akımı sağlayan bir üfleyici kullanılarak toplam on pencere durumu, beş rüzgar yönü, üç duvar genişleme açısı ve üç duvar kalınlığı durumu için en iyi pencere modeli ve pozisyonu belirlenmiştir. Ayrıca sistem dış atmosferde hakim rüzgar yönünde de test edilmiştir. Elde edilen sonuçlardan pencere boyutunun dışarıya doğru eğimli bir şekilde genişlemesi (duvar kalınlığının artması), genişleme açısının artması ve rüzgarın pencereye doğrudan esmesi durumlarında bina içine beslenen hava miktarının arttığı bulunmuştur. Bina içine giren hava akımını pencerenin yanal eğim ve duvar kalınlığı artışının sırasıyla %16-23 ve %3-6 artırdığı, rüzgarın pencereye doğru esme açısındaki artış ile bina içine giren hava akımının hızla azaldığı ve rüzgarın pencere açıklığına paralel estiği durumda hava akımının sıfırladığı görülmüştür. Pencere açıklıklarının binanın hakim rüzgar yönünde ve onun zıt tarafında inşa edilmesinin, bina iç bölmelerinin hava akımının doğrusal akışını kolaylaştıracak şekilde inşa edilmesinin ve bina dışında türbülansa neden olacak girinti ve çıkıntıların mümkün olduğunca azaltılmasının binaların etkin doğal havalandırılması için önemli olduğu görülmüştür.

Późny Gałczyński i Iwaszkiewicz – podobieństwa i różnice
Authors: Sikora Jerzy
Published: August 2022

This article shows the late Gałczyński and Iwaszkiewicz as poets in the last years of life. Gałczyński is represented by two poetic volumes: Kronika olsztyńska (1950) and Pieśni (1953), while Iwaszkiewicz – Mapa pogody (1977) and Muzyka wieczorem(1980). Both creators seek order and peace, and even some form of salvation, through references to the world of nature, to neoclassicism as a worldview and a way of artistic expression. They believe in the sense and power of poetry and art in general. They are connected by music, as well as the sacralization of everyday life. In Gałczyński, aesthetic expression is strongly exposed, and Iwaszkiewicz is also, but more clearly metaphysical in nature. The late poetic collections of both analyzed poets are thematically and formally coherent, at a high artistic level, although we find traces of socialist realism in Gałczyński.

Authors: Al Kuwaiti Ahmed
Published: August 2022

Introduction:

Students' feedback is vital in improving the teaching and learning process in dental schools across the globe, including Saudi Arabia.

Objective:

This study explores the factors influencing the students' perception of faculty members' lecturing skills in Saudi dental schools. It also determines whether there is any gender difference in their perception of lecturing skills.

Methods:

The exploratory study design was utilized to evaluate the factors influencing the dental students' perception of lecturing skills at the selected Saudi dental schools (n=4). This study included the complete student population (n=530) of the undergraduate dental program at those schools during the academic year 2020-2021. A questionnaire titled “Students Survey of Lecturing Skills (SSLS)” was distributed to the students through an online tool. The data of the completed questionnaires (n=426) was subjected to statistical analysis using statistical software.

Results:

The structural equation modeling (SEM) analysis revealed that five factors of SSLS, namely, Organization and Structure of the lectures (OS)”, “Lectures Effectiveness on Learning and Understanding (LEL)”, “Interest and Motivation (IM)”, “Professional Interaction (PI)”, and “Presentation and Classroom Atmosphere (PC)” are vital to evaluate the dental students' perception towards lecturing skills. Also, these five factors have significantly influenced the students' perception of faculty members' lecturing skills in Saudi dental schools. Overall, female dental students are highly satisfied than the male students in regard to their faculty members' lecturing skills.

Conclusion:

OS, LEL, IM, PI, and PC are the significant factors influencing dental students' perception of lecturing skills. These factors can be considered while assessing teaching quality and framing effective strategies for enhancing it at Saudi dental schools.

Published: August 2022

The COVID-19 virus has a significant impact on individuals around the globe. The early diagnosis of this infectious disease is critical to preventing its global and local spread. In general, scientists have tested numerous ways and methods to detect people and analyze the virus. Interestingly, one of the methods used for COVID-19 diagnosis is X-rays that recognize whether the person is infected or not. Furthermore, the researchers attempted to use deep learning approaches that yielded quicker and more accurate results. This paper used the ResNet-50 module based on the Neutrosophic (NS) domain to diagnose COVID patients over a balanced database collected from a COVID-19 radiography database. The method is a future work of the N. E. M. Khalifa et al.’s method for NS set significance on deep transfer learning. True (T), False (F), and Indeterminate (I) membership sets were used to define chest X-ray images in the NS domain. Experimental results confirmed that the proposed approach achieved a 98.05% accuracy rate outperforming the accuracy value acquired from previously conducted studies within the same database.
The Influence of Provaping “Gatewatchers” on the Dissemination of COVID-19 Misinformation on Twitter: Analysis of Twitter Discourse Regarding Nicotine and the COVID-19 Pandemic

Published: August 2022

Background

There is a lot of misinformation about a potential protective role of nicotine against COVID-19 spread on Twitter despite significant evidence to the contrary. We need to examine the role of vape advocates in the dissemination of such information through the lens of the gatewatching framework, which posits that top users can amplify and exert a disproportionate influence over the dissemination of certain content through curating, sharing, or, in the case of Twitter, retweeting it, serving more as a vector for misinformation rather than the source.

Objective

This research examines the Twitter discourse at the intersection of COVID-19 and tobacco (1) to identify the extent to which the most outspoken contributors to this conversation self-identify as vaping advocates and (2) to understand how and to what extent these vape advocates serve as gatewatchers through disseminating content about a therapeutic role of tobacco, nicotine, or vaping against COVID-19.

Methods

Tweets about tobacco, nicotine, or vaping and COVID-19 (N=1,420,271) posted during the first 9 months of the pandemic (January-September 2020) were identified from within a larger corpus of tobacco-related tweets using validated keyword filters. The top posters (ie, tweeters and retweeters) were identified and characterized, along with the most shared Uniform Resource Locators (URLs), most used hashtags, and the 1000 most retweeted posts. Finally, we examined the role of both top users and vape advocates in retweeting the most retweeted posts about the therapeutic role of nicotine, tobacco, or vaping against COVID-19.

Results

Vape advocates comprised between 49.7% (n=81) of top 163 and 88% (n=22) of top 25 users discussing COVID-19 and tobacco on Twitter. Content about the ability of tobacco, nicotine, or vaping to treat or prevent COVID-19 was disseminated broadly, accounting for 22.5% (n=57) of the most shared URLs and 10% (n=107) of the most retweeted tweets. Finally, among top users, retweets comprised an average of 78.6% of the posts from vape advocates compared to 53.1% from others (z=3.34, P<.001). Vape advocates were also more likely to retweet the top tweeted posts about a therapeutic role of nicotine, with 63% (n=51) of vape advocates retweeting at least 1 post compared to 40.3% (n=29) of other top users (z=2.80, P=.01).

Conclusions

Provaping users dominated discussions of tobacco use during the COVID-19 pandemic on Twitter and were instrumental in disseminating the most retweeted posts about a potential therapeutic role of tobacco use against the virus. Subsequent research is needed to better understand the extent of this influence and how to mitigate the influence of vape advocates over the broader narrative of tobacco regulation on Twitter.

Abstract: Language is the unit of our whole communication system. As we all know there are many languages in our world depending on their geographical location, so to remove this language differences or language barrier ,here we explain language translator system in this paper. It focuses on the translator system from English to Bengali and vice versa using machine translation. Bangla is widely spoken language and it is the fifth most spoken native language and the seventh most spoken language by the overall variety of speaker in the world. But there are only a few researches in Machine Translation (MT) for Bangla have been seen in the literature previously. Therefore this paper represents to explain a MT system for English-Bangla and BanglaEnglish translation. Our focus is to help the students to feel a comfort to understand their lesson in different languages. Machine Translation is a revolutionary technology , and day by day it improves. The newest phase of machine translation is Neural Machine Translation (NMT), which is based on the development of artificial intelligence. In this paper we are proposed a type of English-Bangla language translator which based on the Encoder-Decoder model of NMT.

Abstract: The global coronavirus disease pandemic of 2019 (COVID-19) is escalating. In the global fight against COVID19, medical imaging such as computed tomography (CT) and X-rays is crucial, and recently developed artificial intelligence (AI) technologies are enhancing the power of the imaging instruments and assisting medical professionals. Here, we examine the quick reactions to COVID-19 from the medical imaging community (driven by AI). AI-powered picture acquisition, for instance, can considerably assist in automating the scanning process and also reorganise the workflow with little touch to patients, offering the best protection to the imaging technicians. Additionally, AI can increase productivity by precisely identifying infections in X-ray and CT images, allowing for later quantification. Additionally, computer-aided platforms support radiologists in their clinical judgments, such as disease diagnosis, monitoring, and prognosis. Thus, we discuss all of the COVID-19-related medical imaging and analysis methods used in this review study, including image acquisition, segmentation, diagnosis, and follow-up
Womens Safety Device with GPS Tracking and Alert

Published: August 2022

Abstract: Nowadays, the amount of violence against women has increased by many fold due to the greater exposure of women in every field of life. It has now become a major issue. The crime rate is on the spike. The recent spate of crimes against women, particularly rape instances, has been terrifying. Women's safety in India has become a contentious issue as a result of such crimes. Despite international agreements, new legislation, and gender movement, women continue to be particularly susceptible to assault. Looking towards all these issues, we proposed a device which will be really very helpful to women. The system serves four main purposes, first to send the victim's location to the preprogrammed contact numbers with the help of GPS and GSM. Secondly, she can turn the buzzer on so that nearby people can help her to get out of the situation. Storing the women's pulse rate to ThingSpeak cloud with the help of WiFi ESP8266 and sending the same data to registered contact numbers will be the third main purpose of this device. Along with this the fourth main purpose is that she can give a shock to the abuser just by turning the other switch on and touching the device to the abuser's body so that current will pass through him. That shock will not kill the abuser but women will get a chance to escape from the location.

Vascular streak dieback (VSD) is one of the main diseases on cocoa that can cause a decrease in production and even death on susceptible plants. The use of selection criteria is very important in the selection process at the seedling phase, young plants and even mature plants in order to support the breeding process of resistant varieties. The aim of the study was to determine the characteristics of flush including flush color, stomata characters and duration of flush color change to green or towards mature leaves as one of the selection indicators for VSD resistance in cocoa. The research was conducted at Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute, Jember, Indonesia. Study of flush color and stomata characters was conducted using a randomized complete block design consisting of four cocoa genotypes with different levels of resistance, classified as resistant to VSD disease (Sulawesi 1, PNT 16) and as susceptible (BCL and BL 50). Each clone was repeated three times and each replication consisted of three plant samples. Flush color duration study was carried out on six cocoa genotypes as treatments, three genotypes with resistant to VSD (PNT 16, Scavina 12, Sulawesi 1) and three genotypes as susceptible to VSD (BL 50, BCL, Criollo 22). Each treatment was repeated three times and each replication consisted of three plant samples. The results showed that the resistant genotypes showed a tendency to have lower chlorophyll and anthocyanin content than the susceptible ones. The stomata character in the resistant genotypes was not different than the susceptible ones, however, the resistant genotype showed that the stomata density at flush tended to be lower. The duration of flush color change to mature leaves (green) in resistant genotypes was significantly faster than susceptible genotypes.

The laryngeal framework surgery (LFS) is an operation to correct the position and tension of the vocal cords by changing the laryngeal cartilage and muscles. LFS such as type 1 thyroplasty, arytenoid adduction, and arytenopexy is performed to improve the voice of patients with unilateral vocal cord paralysis. It is known that the voice improvement effect of LFS in patients with unilateral vocal cord paralysis is excellent and lasts for a long time. LFS can also be operated under local anesthesia. Complications are not common, however, severe complications like airway obstruction could occur after the operation. Recently, several other attempts to modify the traditional surgical method have been reported. This review is intended to be helpful in understanding the characteristics and changes in laryngeal framework surgery.
Hunminjeongeum Phonetics (II): Phonetic and Phoniatric Consideration for Explanation of Designs of Initial and Final Consonant Letters
Authors: Choi Hong-Shik
Published: August 2022

Hunminjeongeum had 17 initial consonant letters. Among them, five consonant letters, those are ㄱ (牙音, molar sound letter), ㄴ (舌音, lingual sound letter), ㅁ(脣音, labial sound letter), ㅅ (齒音, dental sound letter), ㅇ (喉音, guttural sound letter), were served as chief consonants. There was no argument that consonant letters were made by symbolizing the shape of vocal organs during phonation of them. It could be phoniatrically explained that all of five chief consonants were morphologically symbolized from left lateral view of vocal tract during articulation. Although ‘ㄱ’ was known as molar sound, it was not modeled the shape of molar tooth but modeled the shape of tongue at molar teeth bearing area. The same principle applies to ‘ㅅ’, and it was represented the shape of upper surface of anterior tongue instead of incisor teeth. ‘ㄴ’ was a lingual sound and directly shaped the shape of tongue. ‘ㄷ’ was made by addition of a stroke ‘ㅡ’ meaning hard palate above ‘ㄴ’. ‘ㅁ’ was represented the shape of lateral view of anterior mouth. ‘ㅇ’ was looked like shaping left lateral view of laryngopharyngeal space.

Background and Objectives Tracheostomy is a relatively safe procedure, and the recent emergence of COVID-19 has raised the need to perform tracheostomy immediately in the bed of an intensive care unit (ICU) rather than an operating room. The purpose of this study was to determine the occurrence of complications related to surgical tracheotomy performed in the ICU by an ENT specialist.Materials and Method From March 2019 to January 2022, a total of 101 patients underwent tracheostomy in the ICU. Demographics and complications were classified according to postoperative period.Results Within 24 hours after the procedure, bleeding events were confirmed in 2 patients (2.0%) with mild bleeding. One case (1.0%) of ventricular fibrillation occurred shortly after the procedure. There were no complications from 24 hours to 1 week after procedure. After one week, 4 patients (4.5%) had a local infection, and 3 patients (3.4%) had a tube obstruction. During all follow-up periods, there were no serious side effects such as death, major vascular injury, pneumothroax. No complications were observed throughout the entire period in 6 COVID-19 patients.Conclusion The number of complications of surgical tracheotomy in the ICU performed by a specialist was lower than in previous studies, and there were no complications that delayed treatment or endangered life. The ENT training hospitals should provide sufficient training opportunities for residents to perform surgical tracheostomy and strive to minimize complications associated with the procedure and pre- and post-operative management under the detailed guidance and supervision of specialists.

Published: August 2022

This letter studied the phase error in the frequency-interleaving
digital-to-analog converter (FI-DAC) and proposed a comprehensive phase
estimation method. Firstly, the model of FI-DAC system was established,
and the phase error were considered that consists of three parts: time
delay error, initial phase error and nonlinear phase error. By analyzing
the phase function characteristics of the system, the least squares (LS)
was used to linearly fit the phase functions of the non-overlapping
bands to estimate both the time delay and initial phase of each sub-band
channel. Then, the nonlinear phase error of the system was estimated by
the difference between the system phase function and the estimated
linear phase function. Finally, the effectiveness of the proposed
estimation method was verified by the built FI-DAC test bench.
