Published: February 2020

Abstract
Background

Three-dimensional (3D) printing is an emerging technology that is widely used in medical education. This study compared 3D printed models with conventional models to provide a better understanding of the use of 3D printed models in the teaching of anatomy.

Methods

PubMed, Embase, EBSCO, SpringerLink, and Nature databases were searched systematically for studies published up to December 2019 in the English language. This study complies with PRISMA guidelines. In this study, a meta-analysis of continuous data and binary data was carried out. Both descriptive analysis and statistical analysis were adopted.

Results

Compared with students in the conventional group, students in the 3D printing group showed several advantages in performance testing, time consumption, students' intention, and usefulness. The leave-one-out method further confirmed the stability of the results.

Conclusions

Compared with students in the conventional group, students in the 3D printing group had advantages in answering accuracy and answering time. For most anatomical sites, the 3D group has certain advantages in terms of test scores and time consumption. More students in the 3D printing group were satisfied with their learning compared with students in the conventional group. The role of the 3D printing model in human anatomy education is worth looking forward to.

Authors: Chekole Seyfu , Mihretu Awoke , Teferra Solomon 
Published: February 2020

Abstract
Background: Khat (Catha edulis) chewing has been a highly prevalent practice among youth in Ethiopia. Although several studies investigated its adverse effects, there is a gap in evidence on treatment experience of youth with khat use. Therefore, this study explored the perception of youth on khat chewing and their treatment practice. Methods: The study employed a qualitative study design. The data was gathered through in-depth interviews (N=6), focus group discussions (N=15) and key informants (N=2) interview using purposive sampling. Audio recorded data was manually transcribed and translated, and thematically analyzed. Results: The study found that personal, social and environmental factors were responsible for the habit of chewing khat. Most respondents reported benefits or positive consequences of khat use. They endorsed that khat helps them to feel relaxed, relieve tension and stress, and feel happy, although many admitted feeling depressed after the effect wanes. It would also make them alert, active, and energetic. Participants also reported that khat was easily available and khat use was a social behavior. They learned it from their elders. To manage the negative effects of khat, participants took different coping measures such as drinking too much water, taking alcohols and milk to manage dehydration and break the feeling high. Conclusion: Youth perceived khat use as habitual practice. They didn’t have any modern treatment experience, except personal coping strategies. Future studies should emphasize on khat use literacy, screening, and treatment engagement especially for problematic khat users.

Abstract
Background: Serum uric acid (SUA) is strongly associated with hypertension and is associated with a variety of cardiovascular diseases. In this study we aimed to investigate the predictive effect of SUA and blood pressure on the left atrial (LA) size in Chinese south population. Methods: In this cross-sectional study, we investigated the association between SUA and LA diameter and studied the risk of LA enlargement among subjects with and without hyperuricemia (HU) in different grades of blood pressure in a single-center database (n=5392). Results: The LA diameter was significantly correlated with SUA(r=0.31, P<0.001). The incidence of LA enlargement was significantly greater in subjects with HU than in those without HU [25.7% vs. 14.2%, P<0.001; odds ratio (OR) = 2.09, 95% confidence interval (CI) = (1.78,2.45)], especially in women [21.8% vs. 7.4%, P<0.001; OR=3.50, 95%CI= (2.35, 5.22)]. In subjects with hypertension (≥140/90 mmHg) and HU, the risk of LA enlargement was 7.90 times higher than those with ideal blood pressure (< 120/80 mmHg) and normal SUA [33.1% vs. 5.9%; P<0.001, OR=7.90, 95% CI= (5.87,10.63)]. At the same blood pressure level, the risk of LA enlargement in HU subjects was higher than that in normal SUA (P<0.01). After adjustment for blood pressure, the effect of HU on LA size still exists[public OR=1.82, 95% CI=(1.54,2.14), P<0.001]. Conclusions: HU is an independent risk factor of LA enlargement in Chinese south population. SUA and blood pressure play a synergistic role in predicting the increase of LA diameter.

An incremental meter placement method for state estimation considering collinear measurements and high leverage points
Authors: Abood Hatim G. , Sreeram Victor , Mishra Yateendra 
Published: February 2020

Abstract
The performance of the power system state estimation (SE) is influenced by the configuration of the meters and measurement redundancy. Therefore, the measurement set needs to be updated by installing new SCADA meters and phasor measurement units for improving the quality of the SE solution. However, the potential inconsistency between the existing meters and the new meters should be addressed. Otherwise, the additional meters may lead to numerical problems such as collinearity (linear dependence due to duplicated measurements) and the existence of high leverage points (HLPs) (influential measurements). Hence, this paper proposes an incremental meter placement method. The proposed method utilizes the HLPs and aims to improve the numerical performance of the SE and facilitate the elimination of bad data. The cuckoo search optimization is used for selecting the optimal locations and the numbers of the new meters. The performance of the proposed algorithm is tested on UK 18-bus, the IEEE 30-bus, and 118-bus systems and simulation results show improvements in the quality of the SE solution.

Bridging the Digital Divide Among Racial and Ethnic Minority Men Who Have Sex With Men to Reduce Substance Use and HIV Risk: Mixed Methods Feasibility Study
Authors: Hsiang Elaine , Offer Claudine , Prescott Maximo , Rodriguez Amy , Behar Emily , Matheson Tim , Santa Maria Diane , Santos Glenn-Milo 
Published: February 2020

Background
Ecological momentary assessment (EMA) is a promising data collection tool for mobile health interventions targeting episodic health behaviors. For substance-using men who have sex with men (SUMSM), EMA is becoming more widely utilized in efforts to characterize substance use and sexual risk factors for HIV transmission. However, recent literature demonstrates emerging concerns over compliance and lower EMA engagement and data concordance among racial and ethnic minority SUMSM.

Objective
This study aimed to provide a qualitative evaluation of the barriers and facilitators of EMA as a data collection tool among racial and ethnic minority SUMSM.

Methods
Between October and November 2017, 45 racial and ethnic minority SUMSM were recruited from a list of prior research participants at the San Francisco Department of Public Health to participate in daily EMA surveys on their substance use and sexual health behaviors for 1 week, followed by in-person focus groups (FGs). A total of 4 FGs explored the participants’ experiences with the surveys, issues regarding privacy and confidentiality, and suggestions for improvement. Qualitative analysis was performed using content analysis. Descriptive statistics and Fisher exact tests were used to assess the associations between demographics or substance use behaviors and EMA completion.

Results
Overall, 93.9% (295/314) of all delivered surveys were initiated, and of those, 98.0% (289/295) were completed. Neither participant demographics, including race (P=.65) or age (P=.43), nor substance use behaviors, including the frequency of alcohol (P=.40) or methamphetamine (P=.91) use or any cocaine (P=.28), crack (P=.99), or polysubstance use (P=.24), were found to be associated with survey completion. Overall, participants were receptive to the text message–based EMA surveys. Facilitators included survey timing, user-friendly survey design, survey-stimulated self-reflection, coding of sensitive phrases, and other privacy benefits of a mobile survey. Barriers included an inability to correct texting errors and participants’ perception of judgment or stigmatization related to questions about condomless sex. To improve EMA compliance and uptake, participants suggested adding response confirmations, clarifying survey language, and continuing to diversify the study audience.

Conclusions
EMA appears to be feasible and acceptable among this sample of racial and ethnic minority SUMSM. Close attention to EMA study design and the development of nonjudgmental, contextualized questions regarding stigmatized health behaviors may be critical to further improve EMA compliance.

Published: February 2020

Bitcoin is a crypto currency introduced by Satoshi Nakamoto in 2008. It has the features of decentralization cross-border and fixed total amount and has become one of the most widely used crypto-currencies. Bitcoin, as a new digital currency system, innovatively makes the use of cryptographic elements and consensus mechanisms and builds up a secure decentralized system. The Blockchain, as the core of Bitcoin, uses peer-to-peer network communications and backs up transaction data in every node of the system, thus creating a huge distributed public book. It is essentially a decentralized distributed ledger database, and the decentralization means that the transaction is broadcast to the entire network, where everyone is involved in book keeping. In order to make every participant in the Blockchain willing to participate in the bookkeeping, the reward mechanism of the Bitcoin system is mining. This article first introduces the concept of Blockchain technology, then expounds the principle and the operation mechanism of the Bitcoin and the Bitcoin mining principle, introduces an example of Bitcoin mining in-depth study and analysis, finally, summarize and prospect the development of the Bitcoin mining.
The Intoxication of Power in George Orwell’s Nineteen Eighty Four (1949) and Aldous Huxley’s Brave New World (1932)
Authors: Khatir Hadjer 
Published: February 2020

George Orwell’s Nineteen Eighty Four (1949)and Aldous Huxley’s Brave New World (1932) stand as two powerful works of art that emanated from a mere disorder and fragmentation. To put it differently, this work of art emanated from a world that underwent an extremely rigorous political transformations and cultural seismology. This is a world that has witnessed an overwhelming dislocation. All those upheavals brought into being a new life, that is to say, a reshuffled life .A new life brings forwards a new art. This research, accordingly, attempts to put all its focus on two modernist visionary works of art that have enhanced a completely new system of thought and perceived the past, the present, and even the future with an entirely new consciousness. In the world of Nineteen Eighty Four and Brave New World, power seems to get beyond of what is supposedly politically legitimate. This power has paved the way for the emergence of a totalitarian system; I would rather call it a totalitarian virus. This system has emerged with the ultimate purpose of deadening the spirit of individualism, rendering the classes nothing but “docile masses”. I will be accordingly analysing how power becomes intoxicating. In other words, I will attempt to give a keen picture of how power becomes no longer over things, but rather over men according to Nietzsche’s philosophical perception of “The Will to Power”.
Stuck Pipe Mitigating During Drill Pipe Connection Using Rotation Continuous Circulation Tool

Published: February 2020

Avoiding stuck pipe incidents has a tremendous impact on the efficiency of drilling operations in the oil and gas field. Accumulated cuttings in the drilling BHA due to sudden stop of mud circulation could be the reason of mechanical stuck pipe. The stationary time while making connection might be the reason for getting differential pressure stuck pipe. A rotational continuous circulation tool (RCCT) has been developed to eliminate this risk.
The RCCT allows for continuous circulation and rotation while making connections. It is a 4-inch drill pipe sub with a rotating sleeve. The sleeve is equipped with side-entry port. A side-entry hose, coming from the manifold, is connected to drill pipe through this side-entry port when needed. When operating the mud pump, the mud will move inside the side-entry hose going inside the drill pipe. This will provide continuous circulation. In order to provide continuous rotation, the rotary table is used.
RCCT was trial-tested twice. In the latest trial, 300 ft of open-hole were drilled. The tool was successfully operated, maintaining both circulation and rotation during the connection time, with some considerations. When connecting RCCT, the length of the drill pipe stand increases by 4 to 6 ft. This will need a change of the links length from 11 ft to 13 ft to allow enough space between the Top Drive System (TDS) and the top tool joint. Also, there are limitations in some rigs regarding the height of the crown, where there is a possibility of hitting it when raising the TDS.
This work summarizes the design, the operational considerations, and the deployment details of rotational continuous circulation tool. A trial-test is discussed as a demonstration.

Published: February 2020

The favorable development of the country’s economy depends on the correct distribution of its resources, meanwhile, the higher the return on capital ratio, taking into account all existing risks, the more promising economic development in the long term. Financial literacy of Russian citizens is an important aspect of the financial market and the financial system as a whole, which affects the distribution of resources in the country. The purpose of the study is to establish the relationship between financial literacy and savings in the conditions of digitalization.The main resource possessed by the population are their savings. In a market economy, there is a wide variety of savings and investment opportunities, while it is quite difficult for an individual who does not have a sufficient level of knowledge in the field of finance to make the right decision about the storage and distribution of his temporarily free cash. This can lead to excessive accounts payable, fraud, dependence on the crisis in the country, and as a result – to the loss of part of the accumulated funds. Recently, one can notice a growth trend in cash incomes and savings of the population, as well as an expanding market for financial products and services, which increases personal responsibility for financial decisions made by an individual.In this regard, the problem of increasing financial literacy is facing the state quite acutely, because economic growth, investment attractiveness, development of the financial market, stability of the financial system and increasing the competitiveness of the Russian economy depend on it.

Authors: Palesh S Rajkondawar  , Amit B Patil  
Published: February 2020

Nano-sponges belong to the category of hyper-cross linked polymer which is based on the colloidal structure. Nano-sized carriers are developed recently and are being used to deliver poorly water soluble drug by modifying the pharmaco-kinetic parameter and provide enhanced prolonged release. As a new class of chemo-therapeutic agents is being developed, formulation is getting difficult to issues such as poor solubility, low loading capacity and less entrapment of the drug in the drug delivery system. Nano-sponges have shown to deliver the most complex and challenging Chemo therapeutic drugs due to its amphiphilic nature. Nano-sponges tend to adhere to the tumor through complex bonding and release the drugs at the tumor site,in response to the stimuli such as temperature and pH thus providing the much needed targeted drug delivery. Nano-sponge delivery system has been able to resolve the bio-availability, dose regime, enhanced formulation flexibility issues and fewer side effects while delivering the chemo-therapeutic drugs. Nano-sponges are usually prepared by cross-linking suitable polymer such as Beta-cyclodextrin with cross-linkers. The below comprehensive articles is a brief review of all chemo-therapeutic agent formulated in the Nano-sponge and various methods for the synthesis of Nano-sponges and loading of the active components in the Nano-sponge drug delivery system.

Published: February 2020

The article identifies the features of the use of composite reinforcement in the pile and strip foundation of a two-story house. When designing the foundations, the complex geological conditions of the construction site were taken into account: a high level of groundwater, their aggressiveness with respect to metal reinforcement (seasonal fluctuation of water supply and water treatment at the time of engineering and geological surveys at a level of 2.8 m); the possibility of landslide processes on the slopes; insufficient knowledge and anisotropy of the properties of the bulk layer, significant thickness of the bulk layer, excluding its removal and replacement. An analytical calculation and a numerical experiment were carried out, the following features of the use of composite reinforcement were established:
more effective in strip foundations is fiberglass reinforcement, resistant to aggressive influences; ASK is advisable to use only in lightly loaded pile-tape foundations, or with a small pitch of piles due to low rigidity characteristics of ASK. With a significant load on the structures, it is recommended to use combined reinforcement: in areas of pure compression and tension using ASK, and in bending zones - metal reinforcement.

Published: February 2020

People assume that cancer is a deadly disease. The communication gap between doctor and their patients results in incomplete information obtained by people with cancer. This research was conducted using a qualitative approach in order to explore the meaning of cancer for cancer sufferers in Bandung Cancer Society. Theories used as references are phenomenology and symbolic interactionism. The results of the study of 10 informants indicated that cancer is a very frightening disease; cannot be cured and there is no life expectancy; cancer is caused by unhealthy life style; and yet cancer increases acts of worship. All informants as cancer survivors made efforts to survive by following the doctor's advice. Another result of this study states that communication that takes place between cancer survivors and other fellow sufferers in Bandung Cancer Society can change the view of cancer, motivate and raise the spirit of life.
Los Grupos de Innovación Educativa GIE: Una alternativa válida para los Docentes Universitarios
Authors: Pesántez Avilés Lauro Fernando 
Published: February 2020

Las Instituciones de Educación Superior de América Latina no necesariamente han manejado un escenario de vanguardia en los procesos de la investigación científica, sea porque su tradición académica estuvo orientada, especialmente, al ámbito de la docencia o, porque se ha subestimado el potencial de sus claustros académicos para generar conocimiento o, incluso, por las precarias fuentes de financiamiento que han soportado los proyectos universitarios, por lo que, históricamente, se ha privilegiado la enseñanza y la extensión sobre la investigación.
Sin embargo, de lo antes mencionado, no deja de ser verdad que, en más de una ocasión, los cuerpos docentes, muchas veces en solitario y con insuficientes estructuras de gestión universitaria, han solventado soluciones pertinentes a los desafíos que su entorno sociocultural les ha sabido requerir a título de la función investigación. Ante la dualidad presente, es necesario desmitificar aquellas lógicas que privilegian la visión de que la investigación solo puede ser gestada por aquellos con grandes dotes disciplinares o que es particular proceso de los que poseen un grado científico del más alto nivel.
