Published: July 2019

In recent years, the concept of edutainment has been introduced to the field of education. It is a blended word which has been formed from education and entertainment. The lion aim of this blending is to enhance the process of education through entertainment materials. The researchers have applied this concept to investigate students’ tendencies to use various entertaining materials in their learning process at the University of Halabja\ department of English language for the academic year (2018-2019). The aim of this study is to expose the value and need of edutainment in the process of learning among these students. To achieve this goal, the researchers grounded a theoretical background about some diverged entertainment devices and their impacts on students' learning achievements. Then, formed an academic questionnaire to detect the scope of the use of entertainment sources by these students and the knock of them over their learning achievements. At the end, they analyzed and sieved the results of this questionnaire and concluded the study with their proper recommendations.
Assessing the Appeal of Instagram Electronic Cigarette Refill Liquid Promotions and Warnings Among Young Adults: Mixed Methods Focus Group Study (Preprint)
Authors: Laestadius Linnea I , Penndorf Kendall E , Seidl Melissa , Cho Young I
Published: July 2019

BACKGROUND

While marketing for electronic cigarette refill liquids (e-liquids) is widespread on Instagram, little is known about the post elements that create appeal among young adult Instagram users. Further information is needed to help shape regulatory strategies appropriate for social media.

OBJECTIVE

This study examined young adult Instagram user perceptions of actual e-liquid marketing posts and US Food and Drug Administration (FDA)–mandated nicotine addiction warning statements on Instagram.

METHODS

A series of 12 focus groups (n=69) were held with non–tobacco users, vapers, smokers, and dual users in Wisconsin between September and December 2018. Participants discussed the elements of posts that they found appealing or unappealing, in addition to completing a survey about each post and e-liquid. Focus group transcripts were analyzed by smoking status using a framework analysis approach.

RESULTS

Although willingness to try e-liquids was highest among nicotine users, focus group discussions indicated that Instagram posts promoting e-liquids held appeal for individuals across smoking statuses. The primary elements that created appeal were the perceived trustworthiness of the Instagram account, attractive design and flavor visuals, and promotion of flavors and nicotine levels that met personal preferences. Post appeal was reduced by references to vaping subcultures, indicators that the post creator did not take nicotine addiction seriously, and FDA-mandated nicotine warning statements. Non–tobacco users were particularly drawn to posts featuring nicotine-free e-liquids with attractive visual designs and flavors known from foods.

CONCLUSIONS

Young adults consider a broad range of elements in assessing the appeal of e-liquid marketing on Instagram, with minor but notable distinctions by smoking status. Non–tobacco users are uniquely drawn to nicotine-free e-liquids and are more deterred by the FDA’s mandated nicotine addiction warning statements than those from other smoking statuses. This suggests that it may be possible to tailor policy interventions in a manner that helps to reduce novel uptake of vaping without significantly diminishing its potential harm-reduction benefits.
Patient-Reported Outcome Measures in Cystic Fibrosis: Protocol for a Systematic Review (Preprint)
Authors: Ratnayake Irushi , Ahern Susannah , Ruseckaite Rasa
Published: July 2019

BACKGROUND

Patients with cystic fibrosis (CF) can struggle with burdensome symptoms and treatment regimens that negatively affect every aspect of their life. As physiological parameters can fail to capture these complications, the assessment of health-related quality of life (HRQOL) has gained prominence. HRQOL can be measured using standardized patient questionnaires called patient-reported outcome measures (PROMs). The Australian Cystic Fibrosis Data Registry (ACFDR) collects clinical data on adult and pediatric patients with CF. The incorporation of PROMs into the ACFDR would enable monitoring of HRQOL trends, benchmarking of HRQOL outcomes, and support of HRQOL research in CF.

OBJECTIVE

Prior to incorporation of a PROM in the ACFDR, this systematic review was planned to evaluate whether any suitable PROMs are currently being used for CF.

METHODS

This systematic review will be conducted in compliance with the PRISMA-P (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols) guidelines. MEDLINE, EMBASE, Scopus, CINAHL (Cumulative Index of Nursing and Allied Health Literature), PsycINFO, and Cochrane Library databases were searched for articles published between January 2009 and February 2019 on the use of PROMs to measure HRQOL in adult and pediatric patients with CF. Study designs such as observational studies, reviews and validation studies were included. Studies describing randomized controlled trials, dissertations, books, guideline statements, and abstracts were excluded. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) risk of bias checklist was used to assess the methodological quality of included studies. A descriptive synthesis of the results will be undertaken in line with the outcomes of this study.

RESULTS

As of July 2019, the search has been conducted and 4530 records were screened. After two phases of screening, 97 studies were included in the final review and subjected to data extraction. Reviewers are currently in the process of critical appraisal.

CONCLUSIONS

This review will identify any PROM(s) that may be used to measure HRQOL in the ACFDR.

Authors: Weenk Mariska , Bredie Sebastian J , Koeneman Mats , Hesselink Gijs , van Goor Harry , van de Belt Tom H
Published: July 2019

BACKGROUND

Wearable devices can be used for continuous patient monitoring in the general ward, increasing patient safety. Little is known about the experiences and expectations of patients and health care professionals regarding continuous monitoring with these devices.

OBJECTIVE

This study aimed to identify positive and negative effects as well as barriers and facilitators for the use of two wearable devices: ViSi Mobile (VM) and HealthPatch (HP).

METHODS

In this randomized controlled trial, 90 patients admitted to the internal medicine and surgical wards of a university hospital in the Netherlands were randomly assigned to continuous vital sign monitoring using VM or HP and a control group. Users’ experiences and expectations were addressed using semistructured interviews. Nurses, physician assistants, and medical doctors were also interviewed. Interviews were analyzed using thematic content analysis. Psychological distress was assessed using the State Trait Anxiety Inventory and the Pain Catastrophizing Scale. The System Usability Scale was used to assess the usability of both devices.

RESULTS

A total of 60 patients, 20 nurses, 3 physician assistants, and 6 medical doctors were interviewed. We identified 47 positive and 30 negative effects and 19 facilitators and 36 barriers for the use of VM and HP. Frequently mentioned topics included earlier identification of clinical deterioration, increased feelings of safety, and VM lines and electrodes. No differences related to psychological distress and usability were found between randomization groups or devices.

CONCLUSIONS

Both devices were well received by most patients and health care professionals, and the majority of them encouraged the idea of monitoring vital signs continuously in the general ward. This comprehensive overview of barriers and facilitators of using wireless devices may serve as a guide for future researchers, developers, and health care institutions that consider implementing continuous monitoring in the ward.

Clients with hallucinations really need continuous family support both internal and external families. Reduced external family support will cause a heavy burden on the internal family in caring for hallucinatory clients. The reason families bring to the hospital is the inability to treat patient hallucinations at home after hospitalization because hallucinations pose a burden on the family. The purpose of this study was to find out in-depth information about family experience in treating schizophrenic patients who experience auditory hallucinations after hospitalization. This research is qualitative research, the phenomenology approach uses the method of collecting data by in-depth interviews and document review. Data were obtained by in-depth interviews with six participants. The results of the study are two main themes, namely family understanding of recognizing hallucinatory problems after hospitalization and family experience in treating schizophrenic patients with hallucinatory problems.It is hoped that health services will further improve the quality of health services in providing health education to families about how to properly care for hallucinatory patients and families are expected to be able to treat hallucinogenic patients well.

Minimal energy cost of entanglement extraction
Authors: Hackl Lucas , Jonsson Robert H.
Published: July 2019

We compute the minimal energy cost for extracting entanglement from the ground state of a bosonic or fermionic quadratic system. Specifically, we find the minimal energy increase in the system resulting from replacing an entangled pair of modes, sharing entanglement entropy ΔS, by a product state, and we show how to construct modes achieving this minimal energy cost. Thus, we obtain a protocol independent lower bound on the extraction of pure state entanglement from quadratic systems. Due to their generality, our results apply to a large range of physical systems, as we discuss with examples.
VARIATION OF CUTTING PARAMETERS IN THE PROCESS OF TURNING AISI 4340 STEEL ON SURFACE ROUGHNESS
Authors: Lubis M. Sobron Yamin , Siahaan Erwin , Darmawan Steven , Adianto Adianto , Ronald Ronald
Published: July 2019

In the metal machining process, cutting speed and feed rate are cutting parameters that affect the surface quality of the workpiece produced. The use of improper cutting parameters can cause the workpiece surface to be rough, and the cutting toolage to be shorter. This study was conducted to determine the effect of cutting parameters and the use of carbide tools on the surface roughness of metal steel workpieces. The research was carried out using the experimental method of AISI 4340 steel metal workpiece turning using cutting tool coated. Five variations of cutting speed used are: 140 m/min, 150 m/min, 160 m/min, 170 m/min, 180 m/min and three variations in feed rate: 0.25 mm/rev, 0.3 mm/rev, 0.35 mm/rev. After the turning process, the surface roughness of the workpiece is measured using a surface tester. From the results of the study, it was found that the surface roughness value was directly proportional to the feed rate and inversely proportional to the cutting speed. The smallest surface roughness value is 9.56 μm on cutting speed 180 m / min, and feed rate is 0.25 mm/rev.

Published: July 2019

The article presents the results of an empirical research on patriotism and
ethnic identity in Russian (N=187) and Kazakh students (N=156). The research
was conducted with the aim of determining similarities and differences in
patriotism and ethnic identity characteristics between these two groups of
young people. The work uses a set of the following instruments: ?Ethnic
Identity Types?, ?Who Am I??, ?The Scale of Expressive Assessment of
Feelings Connected with Ethnic Identity?, ?The Scale of Expressive
Assessment of Ethnic Identity Manifestation? and ?Patriogramme?. The results
obtained show that Kazakh students have a higher level of patriotism in
comparison with their Russian colleagues. Despite the similarity in ethnic
identity manifestation between Russian and Kazakh students, Russian students
manifest their ethnic identity more moderately than Kazakh students. Besides
positive ethnic identity, Kazakh students reveal a tendency towards ethnic
superiority: they are more committed to their national traditions, customs,
culture and language and more intolerant of intrusion into their national
and ethnic space than Russian students. The results obtained by the research
can be used in the pedagogical work for stimulating positive aspects of
patriotism and ethnic identity developing in young people living in the
contemporary multicultural and polyethnic world.
Distinct Patterns of Daily Glucose Variability by Pubertal Status in Youth With Type 1 Diabetes
Authors: Zhu Jia , Volkening Lisa K. , Laffel Lori M.
Published: July 2019

OBJECTIVE

To evaluate glycemia and metrics of glucose variability in youth with type 1 diabetes, and to assess patterns of 24-h glucose variability according to pubertal status.

RESEARCH DESIGN AND METHODS

Metrics of glycemia, glucose variability, and glucose patterns were assessed by using 4 weeks of continuous glucose monitoring (CGM) data from 107 youth aged 8–17 years with type 1 diabetes for ≥1 year. Glucose values per hour were expressed as percentages relative to the mean glucose over 24 h for a 4-week period. Glucose data were compared on the basis of pubertal status—prepubertal (Tanner stage [T] 1), pubertal (T2–4), and postpubertal (T5)—and A1C categories (<7.5% [<58 mmol/mol], ≥7.5% [≥58 mmol/mol]).

RESULTS

Youth (50% female, 95% white) had a mean ± SD age of 13.1 ± 2.6 years, diabetes duration of 6.3 ± 3.5 years, and A1C of 7.8 ± 0.8% (62 ± 9 mmol/mol); 88% were pump treated. Prepubertal youth had a higher mean glucose SD (86 ± 12 mg/dL [4.8 ± 0.7 mmol/L]; P = 0.01) and coefficient of variation (CV) (43 ± 5%; P = 0.06) than did pubertal (SD 79 ± 13 mg/dL [4.4 ± 0.7 mmol/L]; CV 41 ± 5%) and postpubertal (SD 77 ± 14 mg/dL [4.3 ± 0.8 mmol/L]; CV 40 ± 5%) youth. Over 24 h, prepubertal youth had the largest excursions from mean glucose and the highest CV across most hours compared with pubertal and postpubertal youth. Across all youth, CV was strongly correlated with the percentage of time with glucose <70 mg/dL (<3.9 mmol/L) (r = 0.79; P < 0.0001).

CONCLUSIONS

Prepubertal youth had greater glucose variability independent of A1C than did pubertal and postpubertal youth. A1C alone does not capture the full range of glycemic parameters, highlighting the added insight of CGM in managing youth with type 1 diabetes.
Circulação, transporte público e pensamento urbano: Benjamín Vicuña Mackenna e seu projeto de 1863 para a construção de uma rede metropolitana de bondes em Santiago do Chile.
Authors: Prudant Elisabet
Published: July 2019

Este artigo analisa a importância do paradigma moderno da circulação e o papel do transporte público como ferramentas do pensamento urbano nos primórdios da modernização da cidade de Santiago do Chile. O objeto de análise será o projeto formulado em 1863 por Benjamín Vicuña Mackenna para a construção de uma rede estendida de bondes de tração animal que ligaria o centro de Santiago com os eixos agrícolas, mineiros e populacionais que o rodeavam. A importância deste projeto se funda na concepção de uma rede de trânsito em função de fluxos metropolitanos antes que Santiago experimentasse a metropolização, o que lhe confere um valor excepcional por seu caráter visionário, adiantando-se a problemas que incidirão negativamente no desenvolvimento futuro da capital chilena. Além disso, situa a cidade de Santiago como uma entidade histórica que, longe de se encontrar isolada em seu desenvolvimento, esteve em contato permanente com as localidades suburbanas e rurais de seu entorno.

Essas histórias do proletariado brasileiro, que podem ser lidas de modo independente, também realizam um conjunto. Entre múltiplas personagens e suas vozes, e, com efeito, diante das muitas fraturas que constituem a consciência linguística de tais sujeitos ficcionais, identifica-se um narrador geral da obra, instância responsável pela orquestração do coro. Instrumento da intencionalidade autoral, esse narrador adere às variações linguísticas e discursivas daqueles que representa e fornece aos leitores do romance uma imagem da linguagem popular, responsável pelo que há de poeticamente produtivo em sua condução narrativa.
Analysis of Organic Pangasius value chain in the Mekong Delta, Vietnam
Authors: Nguyen Doan Khoi Le
Published: July 2019

Organic products remain a niche market in most countries and there is relatively little international trade in organic aquaculture products (Smith et al., 2005). The newly emergent organic products tend to exclude small-holders due to reasons of high certification costs, smaller volumes they produce, and tighter control of product quality. The paper looks at some of the opportunities that exist for small-holders to enter organic schemes and compete in the niche markets. Importantly, the constraints and risks that are involved will be debated. The ability of small farmers to organize and obtain the certification is questioned and the mechanisms to facilitate this will be discussed. The value chain concept, quality management, the theory of institutions and transaction cost economics, will be applied to analyze how the coordinated efforts of various stakeholders can be developed to achieve a better product quality and quality assurance.

The Algorithm of Fully Fuzzy Cognitive Map Models
Authors: Ogunti Erastus O. , Somefun Oluwasegun A. , Terkura Benedict T. , Enoch Gideon E.
Published: July 2019

Precision in the real world is covered by imprecision and arithmetic operations serve as the foundations of computation. Since the introduction of Fuzzy Cognitive mapping, the dynamic model used to establish the fuzzy cognitive map, used conventional arithmetic operations on asymmetric fuzzy sets.Therefore, for a cognitive map, to be completely fuzzy, it should incorporate the use of fuzzy arithmetic and fuzzy numbers in describing the concept nodes and the cause-effect lines defining its structure. It then can be stated that the necessary and sufficient condition for a cognitive map to be fully fuzzy is that its dynamic activity or operation, be achieved only through fuzzy mathematics.This paper presents an introductory analysis into the peculiar design of the fully fuzzy structure of the cognitive map.

Authors: Kabari Ledisi Giok , Nwamae Believe B.
Published: July 2019

In Nigeria today, constant fluctuations of exchange rate or volatility is of great importance in one way or the other to the general public because its fluctuation has an effect on the economy. The objectives of the paper were to investigate the recent changes in the naira currency and other world currencies if there appear to be any relationship. Data was obtained from daily exchange rate of different countries’ currencies from 12/10/2005 and 2/11/2018 with 3,190 observations obtainable from the Data and statistics publication of the Central Bank of Nigeria. The study investigates the past recent changes in the naira and four foreign currencies of the world (Pounds, Yen, Cfa and Swiss Franc) and their relationship plotted as signal using MATLAB 2016a.  The four currencies were randomly selected from the list of world currencies. Multiple Linear Regression was used to perform the analysis. The analysis of 3,190 observation resulted in a prediction model that has 97% prediction accuracy, which suggests that under ideal circumstances and baring any natural disaster, total collapse of the economy or major crisis like recession.  The results from the model of this study suggest that fluctuation in currency exchange rate of other currencies has significance on the Nigerian exchange rate and as such should be considered when designing exchange rate policies.
