Authors: AKKURT Gökhan , ALİMOĞULLARI Mustafa
Published: September 2020

Amaç : Kasık fıtığı onarımlarında laparoskopik yöntemlerin kullanımı her geçen gün artarak devam etmektedir. Yapılan çalışmalarda laparoskopik kasık fıtığı onarımları ile açık onarımların benzer nüks oranına sahip olduğu gösterilmiştir. Ayrıca laparoskopik onarımların diğer avantajları arasında postoperatif ağrı ve enfeksiyon riskinin daha düşük olması, hastaların daha erken işe dönüş süresi ve daha iyi kozmetik görünüm sayılabilir. Laparoskopik kasık fıtığı onarımlarında yaygın olarak total ekstraperitoneal (TEP) ve trans-abdominal preperitoneal (TAPP) onarım yöntemleri uygulanmaktadır. Gereç ve Yöntem: Ocak 2018-Temmuz 2019 tarihleri arasında tek taraflı kasık fıtığı nedeniyle laparoskopik TAPP uygulanan 40 erkek hasta çalışmaya dahil edildi. Ameliyat esnasında periton flebinin (PF) sütür ve tacker ile kapatılmasının her iki grup hastada; fıtık tipi, fıtık tarafı, seroma, vizüel ağrı skalası (VAS), ameliyat süresi, postoperatif hemoraji, skrotal hematom ve vücut kitle indeksi (VKI) açısından fark olup olmadığını araştırmayı planladık. Bulgular: Gruplar arasında fark olup olmadığı bağımsız örneklem t testi ile ve kategorik değişkenler ile gruplar arasındaki ilişki ise ki kare testi ile bakıldı. Her iki grupta; fıtık tarafı, seroma ve skrotal hematom, yaş ve VKI açısından fark bulunmazken, PF tacker kullanılarak kapatılan hastalarda 24 saat sonunda VAS değerleri sütür kullanılanlara göre anlamlı derecede yüksek izlendi. Sonuç: Çalışmamızda tacker kullanılan hastaların postoperatif erken dönem VAS skoru sütür kullanılanlara göre istatistiksel olarak yüksek izlenmiş olmasının nedenini kullandığımız tacker’ın non-absorbe olmasına ve transvers kasındaki akut travmaya bağlı olduğunu düşünmekteyiz. Cerrahın tecrübesi ile ilişkili olarak laparoskopik TAPP esnasında PF’inin absorbe tacker kullanılarak kapatılmasının daha kolay uygulanabilir ve daha kısa ameliyat süresine sahip olmasından dolayı güvenli ve etkin bir yöntem olduğu kanaatindeyiz.

The aim of the present study was to determine the effects of one or two doses of prostaglandin F2α (PGF) on the pregnancy rate (PR) in Simmental cows subjected to the Ovsynch or Ovsynch + Controlled internal drug release (CIDR) protocols. On d 0, 100 µg gonadorelin diacetate tetrahydrate (GnRH) was injected into cows in group 1 (n = 50) and group 2 (n = 40) and CIDR was intravaginally inserted. On d 7, 25 mg dinoprost tromethamine (PGF2α, PGF) was administered, and GnRH was injected 56 h later. Fixed-time artificial insemination (TAI) was performed 16 h after GnRH injection. In group 3 (n = 62) and group 4 (n = 63), PGF was administered 7 d following GnRH treatment, and GnRH was injected 56 h later. TAI was performed 16 h after GnRH injection. In groups 2 and 4, a second dose of PGF was injected 24 h after the first dose. Pregnancy was determined by transrectal ultrasonography on d 30 and 60 post-TAI. The pregnancy rate (PR) on d 30 post-TAI was significantly different among the groups: 46%, 55%, 29%, and 36.5%, in groups 1, 2, 3, and 4, respectively (P = 0.048). In addition, the PR was 36.3% and 43.7% in the single PGF and double PGF injection groups, respectively. There was no statistical difference in the PR on d 60 post-TAI (P > 0.05). Pregnancy loss was between 4.34% and 11.11% (P > 0.05). The highest PR in the primiparous cows was observed in group 3 (57.7%). The PR was not significantly different among multiparous cows (P > 0.05). In conclusion, two injections of PGF administered 24 h apart in Simmental cows may increase the PR in the Ovsynch or Ovsynch + CIDR protocols.

Authors: Çiftci Süphan Kaan , Demirarslan Deniz
Published: September 2020

Cyberpunk teknolojinin hat safhaya ulaştığı, yapay zekanın insan zekasına eş değer konuma geldiği, makine-insan birleşimlerinin yaşandığı, transhümanizmin benimsendiği, karanlık ve kaos içeren bir geleceğin tasvir edildiği bir bilim kurgu dalı olarak tanımlanmaktadır. Teknolojinin sürekli olarak devinim ve gelişim halinde olması gelecek yıllarda hayatımızın her alanında teknolojiyle iç içe olmayı gerektirecektir. 1980’lerden bu yana edebiyat başta olmak üzere, müzik, video oyunları ve sinema sektöründe Cyberpunk türünde birçok eser verilmiştir. Özellikle sinema sektörü bu türü kısa sürede benimsemiş ve yıllar içinde değişim göstererek çok sayıda eser sunmuştur. Sinema sektörü Cyberpunk’ı görsel bağlamda bizlere en iyi şekilde aktarmaktadır. Bu araştırmada elli adet Cyberpunk türünde film örnek olarak verilmiş ve aralarından üç adet film, içerdiği iç mekân verileri açısından incelenmek için tercih edilmiştir. Filmler detaylı bir şekilde birden çok kez izlenerek incelenmiştir. Kesin yargıları olmayan, hala gelişmekte ve değişmekte olan Cyberpunk türü ile üretilen filmlerin iç mekân tasarımı açısından benzer özelliklerine değinilmiştir. İncelenen bu üç filmde, iç mekân tasarımı ve mobilya tasarımına dair detaylı bir çalışmanın mevcut olmadığı görülmüştür. Filmlerde ortak olarak iç mekanlar soğuk ve kasvetli olarak tasvir edilmiş, mobilyalar genelde modern ve fütüristik çizgide kullanılmıştır. Gelecek yüzyılda teknolojinin bu denli gelişmesiyle sadece insan-makine birleşimi değil; aynı zamanda mobilya ve iç mekânın teknoloji ile birleşimi de göz önüne alınmalıdır. Bu sayede gelişmiş teknolojiyi insan hayatının yararına, yaşam kalitesini yükseltmek amacıyla kullanmak mümkündür.

Published: September 2020

The article considers the effect of non-Stationary unintentional interference on the earth station of a satellite communications system with Multi-Frequency Time-Division Multiple Access. The influence of non-stationary interference and white Gaussian noise on the earth station reception channel is compared using simulation modeling. The simulation model takes into account the effect of unintentional interference on the synchronization subsystem and the allocation of the boundaries of the transmitted packet of the receiver of the earth station of the satellite communication system. The probability of a bit error was used as a criterion for the quality of the satellite channel operation. The article shows the dependence of the protective ratio on the ratio of the preamble length to the packet length under the influence of pulsed interference. The obtained dependence can be used to assess the noise immunity of an earth station in a satellite communications system under the influence of pulsed interference.

Published: September 2020

This research was motivated by many people who argued that to achieve high achievement in learning, a person must have a high Intelligence Quotient (IQ) because it is a potential provision that will facilitate learning and will result in optimal learning achievement. According to Binet in Winkel (2009), the essence of intelligence is the ability to set and maintain a goal, to make adjustments to achieve that goal, and to evaluate one's condition critically and objectively. However, according to the results of research in the field of psychology, it proves that IQ is not the only factor that affects a person's learning achievement. Many other factors influence a person's learning achievement and one of them is emotional intelligence. The purpose of this study was to determine whether there is a relationship between emotional intelligence and learning outcomes of physics in class X SMA in District Bangko. This research was a descriptive quantitative correlational study. The independent variable in this study was emotional intelligence while learning outcomes were the dependent variable. Questionnaires that consisted of managing one's emotions, motivating oneself, recognizing other people's emotions or empathy, and building relationships (cooperation) with others were used to collect the data. Learning outcome test questions which consisted of measurement material, vectors, motion, and circular motion were used to measure student learning outcomes. The data analysis technique used SPSS 16.0. by testing the normality of the hypothesis, the significance, and the regression equation. The results of the data analysis showed that the coefficient value of the correlation between emotional intelligence and learning outcomes was 0.356. 0.356 <0.5 or close to zero means that there is a weak correlation between emotional intelligence and learning outcomes. To test the hypothesis, it was obtained tcount> t table or 12.042> 1.977 then H0 is rejected. It can be said that there is a significant correlation between emotional intelligence and physics learning outcomes of class X students at SMA Negeri in District Bangko.

Open dumping and uncontrolled landfilling of solid wastes are the most widely practiced waste disposal methods in many cities of the less-developed regions, especially those in sub Saharan Africa. These practices are unsustainable and pose a major threat to the environment and public health. Of particular concern is the leachate produced at the disposal sites, which is concentrated with biological and chemical substances that could contaminate the soil, surface and groundwater sources in the environment. The effects of leachate percolation on the quality of groundwater sources is of great concern especially in sub Saharan Africa, where untreated self-supply groundwater options represent a major source of water supply for many inhabitants. Given this perspective, the physicochemical characteristics of some groundwater samples from wells around a major waste disposal site; Aisami in Kano metropolis, Nigeria, were examined. The samples were collected from the north, east, south and west directions around the disposal site and analysed for parameters that include: pH, turbidity, total dissolved solids, electrical conductivity, total alkalinity, total hardness, Ca+2, Mg+2, Na+, K+, NO3-, SO4(2-), Cl-, Cu+2, Fe+2 ,Mn+2, Pb, Zn, and Cr. Significant concentrations of most parameters were revealed, often above the WHO recommended thresholds. Accordingly, some measures were highlighted towards protecting, preserving and sustaining groundwater quality as a strategic source of water supply in the area and beyond.
A modified immersed finite volume element method for elliptic interface problems
Authors: Wang Quanxiang , Zhang Zhiyue
Published: September 2020

This paper presents a new immersed finite volume element method for solving second-order elliptic problems with discontinuous diffusion coefficient on a Cartesian mesh. The new method possesses the local conservation property of classic finite volume element method, and it can overcome the oscillating behaviour of the classic immersed finite volume element method. The idea of this method is to reconstruct the control volume according to the interface, which makes it easy to implement. Optimal error estimates can be derived with respect to an energy norm under piecewise \(H^{2}\) regularity. Numerical results show that the new method significantly outperforms the classic immersed finite volume element method, and has second-order convergence in \(L^{\infty}\) norm.

Critical length for the spreading-vanishing dichotomy in higher dimensions
Authors: Simpson Matthew J.
Published: September 2020

We consider an extension of the classical Fisher–Kolmogorov equation, called the “Fisher–Stefan” model, which is a moving boundary problem on \(0<x L_{\textrm{c}}\) will eventually spread as \(t \to \infty\) , whereas solutions where \(L(t) \ngtr L_{\textrm{c}}\) will vanish as \(t \to \infty\) . In one dimension it is well known that the critical length is \(L_{\textrm{c}} = \pi/2\) . In this work, we re-formulate the Fisher–Stefan model in higher dimensions and calculate \(L_{\textrm{c}}\) as a function of spatial dimensions in a radially symmetric coordinate system. Our results show how \(L_{\textrm{c}}\) depends upon the dimension of the problem, and numerical solutions of the governing partial differential equation are consistent with our calculations.

Exploring Eating Disorder Topics on Twitter: Machine Learning Approach
Authors: Zhou Sicheng , Zhao Yunpeng , Bian Jiang , Haynos Ann F , Zhang Rui
Published: September 2020

Background

Eating disorders (EDs) are a group of mental illnesses that have an adverse effect on both mental and physical health. As social media platforms (eg, Twitter) have become an important data source for public health research, some studies have qualitatively explored the ways in which EDs are discussed on these platforms. Initial results suggest that such research offers a promising method for further understanding this group of diseases. Nevertheless, an efficient computational method is needed to further identify and analyze tweets relevant to EDs on a larger scale.

Objective

This study aims to develop and validate a machine learning–based classifier to identify tweets related to EDs and to explore factors (ie, topics) related to EDs using a topic modeling method.

Methods

We collected potential ED-relevant tweets using keywords from previous studies and annotated these tweets into different groups (ie, ED relevant vs irrelevant and then promotional information vs laypeople discussion). Several supervised machine learning methods, such as convolutional neural network (CNN), long short-term memory (LSTM), support vector machine, and naïve Bayes, were developed and evaluated using annotated data. We used the classifier with the best performance to identify ED-relevant tweets and applied a topic modeling method—Correlation Explanation (CorEx)—to analyze the content of the identified tweets. To validate these machine learning results, we also collected a cohort of ED-relevant tweets on the basis of manually curated rules.

Results

A total of 123,977 tweets were collected during the set period. We randomly annotated 2219 tweets for developing the machine learning classifiers. We developed a CNN-LSTM classifier to identify ED-relevant tweets published by laypeople in 2 steps: first relevant versus irrelevant (F1 score=0.89) and then promotional versus published by laypeople (F1 score=0.90). A total of 40,790 ED-relevant tweets were identified using the CNN-LSTM classifier. We also identified another set of tweets (ie, 17,632 ED-relevant and 83,557 ED-irrelevant tweets) posted by laypeople using manually specified rules. Using CorEx on all ED-relevant tweets, the topic model identified 162 topics. Overall, the coherence rate for topic modeling was 77.07% (1264/1640), indicating a high quality of the produced topics. The topics were further reviewed and analyzed by a domain expert.

Conclusions

A developed CNN-LSTM classifier could improve the efficiency of identifying ED-relevant tweets compared with the traditional manual-based method. The CorEx topic model was applied on the tweets identified by the machine learning–based classifier and the traditional manual approach separately. Highly overlapping topics were observed between the 2 cohorts of tweets. The produced topics were further reviewed by a domain expert. Some of the topics identified by the potential ED tweets may provide new avenues for understanding this serious set of disorders.

Authors: Rao Qingmao , Zhang Zuyue , Lv Yalan , Zhao Yong , Bai Li , Hou Xiaorong
Published: September 2020

Background

Social media is a powerful tool for the dissemination of health messages. However, few studies have focused on the factors that improve the influence of health messages on social media.

Objective

To explore the influence of goal-framing effects, information organizing, and the use of pictures or videos in health-promoting messages, we conducted a case study of Sina Weibo, a popular social media platform in China.

Methods

Literature review and expert discussion were used to determine the health themes of childhood obesity, smoking, and cancer. Web crawler technology was employed to capture data on health-promoting messages. We used the number of retweets, comments, and likes to evaluate the influence of a message. Statistical analysis was then conducted after manual coding. Specifically, binary logistic regression was used for the data analyses.

Results

We crawled 20,799 Sina Weibo messages and selected 389 health-promoting messages for this study. Results indicated that the use of gain-framed messages could improve the influence of messages regarding childhood obesity (P<.001), smoking (P=.03), and cancer (P<.001). Statistical expressions could improve the influence of messages about childhood obesity (P=.02), smoking (P=.002), and cancer (P<.001). However, the use of videos significantly improved the influence of health-promoting messages only for the smoking-related messages (P=.009).

Conclusions

The findings suggested that gain-framed messages and statistical expressions can be successful strategies to improve the influence of messages. Moreover, appropriate pictures and videos should be added as much as possible when generating health-promoting messages.

Published: September 2020

Background

Information and communication technology may provide domiciliary care programs with continuity of care. However, evidence about the effectiveness and cost-effectiveness of information and communication technology in the context of integrated care models is relatively scarce.

Objective

The objective of our study was to provide evidence on the clinical effectiveness and cost-effectiveness of the BeyondSilos project for patients enrolled in the Badalona city pilot site in Spain.

Methods

A quasi-experimental study was used to assess the cost-effectiveness of information and communication technology–enhanced integration of health and social care, including the third sector (intervention), compared to basic health and social care coordination (comparator). The study was conducted in Badalona between 2015 and 2016. Participants were followed for 8 months.

Results

The study included 198 patients: 98 in the intervention group and 100 in the comparator group. The mean Barthel index remained unchanged in the intervention group (mean change 0.14, 95% CI –4.51 to 4.78; P=.95) but decreased in the comparator group (mean change –3.23, 95% CI –5.34 to –1.11; P=.003). Instrumental Activities of Daily Living significantly decreased in both groups: mean changes of –0.23 (95% CI –0.44 to –0.02; P=.03) and –0.33 (95% CI –0.46 to –0.20; P<.001) in the intervention and comparator groups, respectively. No differences were found in the Geriatric Depression Scale (intervention: mean change 0.28, 95% CI –0.44 to 1.01, P=.44; comparator: mean change –0.29, 95% CI –0.59 to 0.01, P=.06). The intervention showed cost-effectiveness (incremental cost-effectiveness ratio €6505.52, approximately US $7582).

Conclusions

The information and communication technology–enhanced integrated domiciliary care program was cost-effective. The beneficial effects of this approach strongly rely upon the commitment of the professional staff involved.

Background/Purpose: Pneumonia is a common respiratory and life-threatening disease in pediatrics. Virus is an important cause of pneumonia in children, of which Respiratory syncytial virus (RSV) is the most common cause. The aim of this research is to access the clinical, epidemiological features and risk factors of patients suffering from RSV severe pneumonia.

Methods: We studied 250 patients suffering from severe pneumonia caused by RSV from June 2019 to December 2019 in the Respiratory Center of the Vietnam National Children’s Hospital.

Results: In Respiratory Center of our hospital, 3472 hospitalizations caused by pneumonia occurred in the last 6 months in 2019; 7.2% of these caused by RSV severe pneumonia. Pneumonia caused by RSV occurred most in male (66,7%), the rate of male/female = 2/1. The mean age was 4,94 ± 6,04  months. The prevalence of RSV in age groups is, respectively, as follows: less than 3 months (21,3%), from 3 months to 6 months (23,4%), from 6 months to 12 months (27%), from 12 months to 24 months (19%), over 2 years (9,3%). The most common symptoms which were accounted for over 80% were rhinorrhea, cough, wheeze, tachypnea and chest recession. The rate of admission increased sharply in December with 25.1% of cases. All hospitalized patients had respiratory distress symptoms with the frequent changes in blood gas, accounting for 59.2% of hypercapnia. The mean of hospitalization was 6,2 ± 7,4 days.

Conclusion: the rate of RSV infection increased in the last 6 months in 2019. Most of patients who less than 1 year of age were admitted to hospital because of severe clinical symptoms and respiratory distress. Risk factors were related to the severity of RSV severe pneumonia were: premature, mal-nutrition, bronchopulmonary dysplasia.
