Published: May 2020

BACKGROUND

Schizophrenia spectrum disorders (SSDs) are chronic conditions, but the severity of symptomatic experiences and functional impairments vacillate over the course of illness. Developing unobtrusive remote monitoring systems to detect early warning signs of impending symptomatic relapses would allow clinicians to intervene before the patient’s condition worsens.

OBJECTIVE

In this study, we aim to create the first models, exclusively using passive sensing data from a smartphone, to predict behavioral anomalies that could indicate early warning signs of a psychotic relapse.

METHODS

Data used to train and test the models were collected during the CrossCheck study. Hourly features derived from smartphone passive sensing data were extracted from 60 patients with SSDs (42 nonrelapse and 18 relapse >1 time throughout the study) and used to train models and test performance. We trained 2 types of encoder-decoder neural network models and a clustering-based local outlier factor model to predict behavioral anomalies that occurred within the 30-day period before a participant's date of relapse (the near relapse period). Models were trained to recreate participant behavior on days of relative health (DRH, outside of the near relapse period), following which a threshold to the recreation error was applied to predict anomalies. The neural network model architecture and the percentage of relapse participant data used to train all models were varied.

RESULTS

A total of 20,137 days of collected data were analyzed, with 726 days of data (0.037%) within any 30-day near relapse period. The best performing model used a fully connected neural network autoencoder architecture and achieved a median sensitivity of 0.25 (IQR 0.15-1.00) and specificity of 0.88 (IQR 0.14-0.96; a median 108% increase in behavioral anomalies near relapse). We conducted a post hoc analysis using the best performing model to identify behavioral features that had a medium-to-large effect (Cohen d>0.5) in distinguishing anomalies near relapse from DRH among 4 participants who relapsed multiple times throughout the study. Qualitative validation using clinical notes collected during the original CrossCheck study showed that the identified features from our analysis were presented to clinicians during relapse events.

CONCLUSIONS

Our proposed method predicted a higher rate of anomalies in patients with SSDs within the 30-day near relapse period and can be used to uncover individual-level behaviors that change before relapse. This approach will enable technologists and clinicians to build unobtrusive digital mental health tools that can predict incipient relapse in SSDs.
Parental Online Information Access and Childhood Vaccination Decisions in North America: Scoping Review (Preprint)
Authors: Ashfield Sarah , Donelle Lorie
Published: May 2020

BACKGROUND

Immunizing children throughout their early years prevents the spread of communicable disease and decreases the morbidity and mortality associated with many vaccine-preventable diseases. Searching online allows individuals rapid access to health information.

OBJECTIVE

The purpose of this review was to develop an understanding of the existing literature of parents’ online health information-seeking behaviors to inform their vaccination choices for their children and to identify gaps in the literature around parents’ use of online health information and their vaccination choices.

METHODS

A scoping review of peer-reviewed literature from Canada and the United States was performed. The following databases were utilized to perform the search: PubMed, CINAHL, Nursing & Allied Health Database, Scopus, and PsycINFO. The purpose of this review was to examine parents’ use of online information seeking related to vaccine information and to understand how parents utilize this information to inform decisions about vaccinating their children. Of the 34 papers included in the review, 4 relevant themes and subthemes were identified: information seeking, online information resources, online vaccine content, and trust in health care providers.

RESULTS

Examination of the literature revealed conflicting information regarding parents’ use of social media and online resources to inform decisions around vaccinating their children. There is evidence of significant misinformation regarding vaccine risks online. Parents’ digital health literacy levels are unknown and may affect their ability to appraise online vaccination information.

CONCLUSIONS

Parents are seeking vaccine information from online sources. However, the influence of online vaccine information on parental vaccine practices remains uncertain.
Beyond predicting the number of infections: predicting who is likely to be COVID negative or positive (Preprint)
Authors: Zhang Stephen X. , Sun Shuhua , Jahanshahi Asghar Afshar , Wang Yifei , Madavani Abbas Nazarian , Dinani Maryam Mokhtar
Published: May 2020

BACKGROUND

The current COVID-19 pandemic and the severe shortage of testing kits in many countries pose a first and foremost problem in medical informatics—the information on the risk predictors of people who are at greater risk of contracting COVID-19 to enable more targeted infectious disease prevention, communication, testing, and control.

OBJECTIVE

This study aims to identify individuals’ likelihood to be COVID negative or positive, enabling more targeted infectious disease prevention and control.

METHODS

We conducted a primary survey of 521 adults on April 1-10, 2020 in Iran, where the official infection rate was 0.08%. In our sample, 3% reported positive and 15% were unsure whether they were infected. This relatively high positive rate enabled us to conduct the analysis at 5% significance level.

RESULTS

Adults who exercised more were more likely to be COVID-19 negative. Each additional hour of exercise per day predicted a 78% increase in the likelihood of being COVID-19 negative. Adults with chronic medical illnesses were 48% more likely to be COVID-19 negative. In terms of work situation, those who worked from home were the most likely to be COVID-19 negative, and those who had stopped working were the most likely to be COVID-19 positive. Individuals in larger organizations were less likely to be COVID-19 positive.

CONCLUSIONS

This study enables more targeted infectious disease prevention and control by identifying the risk factors of COVID-19 infections from a set of readily accessible information on demographic and work characteristics. We hope this research opens a new research avenue of medical informatics to help healthcare services to predict the individual likelihood of COVID-19 infection by risk factors.

Published: May 2020

UNSTRUCTURED

The coronavirus disease (COVID-19) pandemic has been particularly challenging for nursing home staff and residents. Centers for Medicare & Medicaid Services regulation waivers are burdening staff and affecting how care is delivered. Residents are experiencing social isolation, which can result in physical and behavioral health issues, particularly for persons with dementia. These challenges can be addressed in part through technology adaptations. Full integration of electronic health record systems can improve workflow and care quality. Telehealth can improve access to outside providers, provide remote monitoring, and improve social connectedness. Electronic and audiovisual programs can be used for end-of-life planning and information sharing between nursing home staff and families. Online learning systems and other online resources provide flexible options for staff education and training. Investing in and adapting technology can help mitigate workforce stress and improve the quality of nursing home care during and after the COVID-19 crisis.

Published: May 2020

BACKGROUND

Long-term side-effects associated with different prostate cancer treatment approaches are common. Sexual challenges are the most frequently occurring issues and can result in increased psychological morbidity. It is recognized that barriers to communication can make initiating discussions around sexual concerns in routine practice difficult. Health care professionals need to routinely initiate conversations, effectively engage with patients, and assess needs in order to provide essential support. One proposed method that could support health care professionals to do this involves the use of prompts or structured frameworks to guide conversations.

OBJECTIVE

This study aimed to assess feasibility, acceptability, and satisfaction with the tablet-based Engagement, Assessment, Support, and Sign-posting (EASSi) tool designed to facilitate and structure sexual well-being discussions in routine prostate cancer care.

METHODS

Health care professionals (n=8) used the EASSi tool during 89 posttreatment appointments. Quantitative data were recorded based on program usage and surveys completed by health care professionals and patients. Qualitative data exploring perceptions on use of the tool were gathered using semistructured interviews with all health care professionals (n=8) and a sample of patients (n=10).

RESULTS

Surveys were completed by health care professionals immediately following each appointment (n=89, 100%). Postal surveys were returned by 59 patients (66%). Health care professionals and patients reported that the tool helped facilitate discussions (81/89, 91% and 50/59, 85%, respectively) and that information provided was relevant (82/89, 92% and 50/59, 85%, respectively). The mean conversation duration was 6.01 minutes (SD 2.91). Qualitative synthesis identified the tool’s ability to initiate and structure discussions, improve the “depth” of conversations, and normalize sexual concerns.

CONCLUSIONS

The EASSi tool was appropriate and acceptable for use in practice and provided a flexible approach to facilitate routine brief conversations and deliver essential sexual well-being support. Further work will be conducted to evaluate the effectiveness of using the tablet-based tool in prostate cancer care settings.

Authors: Abdelaal Mohammed Ahmed , Abushanab Dina , Al-Badriyeh Daoud
Published: May 2020

Aim:
To conduct a systematic overview of systematic reviews (SRs) and randomized clinical trials (RCTs) on surfactant therapy in neonatal meconium aspiration syndrome.
Methods:
We searched EMBASE, PROQUEST and PubMed to summarize the different effects of surfactant lung lavage and bolus surfactant therapies in neonates with meconium aspiration syndrome.
Results:
With a total of 1377 patients, three SRs and two RCTs were included in analysis. Surfactant effectiveness was concluded by low-quality SRs, with high risk of bias, which was contradicted by high-quality SRs, with low risk of bias. In SRs, the surfactant lung lavage reduced mortality, need for extracorporeal membrane oxygenation and hospitalization, while the bolus surfactant did not. In recent high-quality RCTs, however, the two modalities did not significantly differ.
Conclusion:
The evidence on surfactant effectiveness and its method of administration is sparse and inconsistent.

Сегодня значительная часть электронных микроскопов оборудована энергодисперсионными рентгеновскими спектрометрами (ЭДС) с соответствующим математическим обеспечением. В результате этого возникает дополнительная возможность – проведение ЭЗМА исследуемого объекта. Руководства по использованию этих спектрометров предлагают достаточно простой и быстрый алгоритм проведения анализа обычно без использования ­каких-либо образцов сравнения (ОС). Такой подход получил название «безэталонный анализ» (БА). Обсуждается развитие БА и проблема правильности определений.
Pentecostalismo de frontera y pentecostalismo de centro. Procesos de fronterización simbólica en el pentecostalismo altiplánico chileno-boliviano 1973-2007
Authors: Mansilla Agüero Miguel Ángel , Leiva Gómez Sandra , Piñones Rivera Carlos
Published: May 2020

The article proposes a reading of the border as a social and cultural construction through the concept of symbolic frontierization. It analyzes the representations and symbolic practices that Pentecostalism constructs on the border, showing the processes that take place between center and border Pentecostalism and specifying what we call an "altiplanization of Pentecostalism". The methodology consists of the systematic review of the “Fuego de Pentecostés” magazine between 1973 and 2007, seeking to analyze such processes in the Chile-Bolivia border. It concludes by synthesizing the main features of this symbolic frontierization and emphasizing the need to deepen the studies on these processes from the methodologies based on the observation of the contemporary contexts.
Migrar, morir y seguir perteneciendo
Authors: Mardones Pablo
Published: May 2020

This article is a result of a strategically situated ethnography on the celebration of the Day of the Dead, carried out between 2008 and 2014 at the Cemetery of Flores and in the south-western neighborhoods of Buenos Aires (Argentina). The data gathered through ethnographic observation and a bibliographic and press review show a Latin American regional dynamic in which we observe from the mid-twentieth century a decline of the celebration of the Day of the Dead in the large cities of those countries that have constructed their national-state identity as “non-Indian”. At the same time, in those countries that have included “Indian” identities in their national imaginaries, the celebration is increasing. The research carried out positions Buenos Aires in both spheres: while the celebration of this festivity has declined among the native population, it has grown among Aymara, Kolla and Quechua migrants from the central Andes. I identify how these migrants generate processes of communalization and relational dynamics in the resignification of the celebration to the deceased and the burial of their own people in Buenos Aires. I suggest that in these processes, the subjects build territorialities and produce new senses of attachment towards the new spaces they inhabit.
La incidencia del Covid-19 en el ejercicio de la garantía legal
Authors: Isler Soto Erika
Published: May 2020

The incidence of the Covid-19 virus in the rights derived from the legal guarantee, in Chilean Consumer Law. At first, it is postulated that this pandemic can indeed be considered as a force majeure, but it does not extinguish the guarantee. However, there are two effects: the suspension of the legal term for its exercise and the emergence of certain duties of conduct. This approach is obtained from the need to safeguard the safety of consumers, as well as from the principles and rules of the statute of limitations, with special reference to Consumer Law.

Enhancement of pulsed laser-induced silicon plasma-assisted quartz ablation by continuous wave laser irradiation
Authors: Rahman Tunzeel ur , Huagang Liu , Qayyum Abdul , Hong Minghui
Published: May 2020

This research article reports the enhancement of quartz ablation by continuous wave (cw) laser irradiation of silicon plasma generated by a pulsed fiber laser. The fiber laser operating at 1064 nm wavelength and 5 ns pulse width is utilized to produce silicon plasma, whereas a cw laser (λ = 808 nm) is used for quartz ablation enhancement. The gap distance between the target and the substrate is 20 μm. The microfeatures and silicon craters are characterized with the help of an optical microscope and a surface profiler. It is observed that the diameter, depth, and volume of the microfeatures increase linearly with the fluence of the cw laser in the range of 3.5–10.2 μJ/cm2. Below the fluence of 3.5 μJ/cm2, there is no significant enhancement in quartz ablation. The maximum increase in diameter, depth, and volume of microfeatures due to cw laser irradiation is 35 ± 6.4%, 198 ± 11.9%, and 443 ± 48.8%, respectively. The analysis of corresponding silicon craters reveals that the silicon ablation rate also increases with the fluence of the cw laser. The variation in size (diameter and depth) and volume of the quartz microfeatures as a function of cw laser fluence is quite identical to the change in the size of silicon craters. The enhancement of quartz ablation is explained by the physical mechanism resulting from the interaction of cw laser with the silicon target.
Effect of dynamic wire feeding on deposition quality in laser cladding process
Authors: Rodrigues Max Baranenko , Silva Rafael Gomes Nunes , Pereira Milton , Silva Régis Henrique Gonçalves e , Teichmann Erwin Werner
Published: May 2020

Laser based material deposition has matured into a well-established industrial technique for precise coating deposition (cladding) and additive layer manufacturing (direct laser metal deposition). Laser cladding is one of the techniques for enhancing the surface performance, hence extending the lifetime of many components in severe corrosive-wear environments. Laser cladding with wire consists in feeding the deposited material as a metallic wire, which is melted by a laser source and manipulated over the deposition volume. This process shows some advantages over powder-based systems such as cleaner processing environment, reduced environmental cost for producing the wire, better surface finishing, and a higher material deposition rate. By means of innovative equipment such as dedicated nozzle and wire feeder systems, well-customized manufacturing strategies can improve the coating quality. Among recent innovations, the change of the wire direction results in a forward final feeding speed. This type of feeding is called dynamic feeding. The controlled movement of the wire is well-known in arc welding, and its synchronization with the arc's electrical parameters gives a drastic increase in stability and controllability. Based on that, the present paper addresses a characterization analysis of the frequency of dynamic feeding process in laser cladding in terms of coating quality. In addition, a dynamic feeding equipment was developed with total flexibility of parameters regulation. Dynamic feeding oscillation showed good stability and lower dilution compared to the conventional method.
Surface functionalization by laser-induced periodic surface structures
Authors: Florian Camilo , Kirner Sabrina V. , Krüger Jörg , Bonse Jörn
Published: May 2020

In recent years, the improved understanding of the formation of laser-induced periodic surface structures (LIPSS) has led to an emerging variety of applications that modify the optical, mechanical, and chemical properties of many materials. Such structures strongly depend on the laser beam polarization and are formed usually after irradiation with ultrashort linearly polarized laser pulses. The most accepted explanation for the origin of the structures is based on the interference of the incident laser radiation with electromagnetic surface waves that propagate or scatter at the surface of the irradiated materials. This leads to an intensity modulation that is finally responsible for the selective ablation in the form of parallel structures with periods ranging from hundreds of nanometers up to some micrometers. The versatility when forming such structures is based on the high reproducibility with different wavelengths, pulse durations and repetition rate laser sources, customized micro- and nanometric spatial resolutions, and compatibility with industrially relevant processing speeds when combined with fast scanning devices. In this contribution, we review the latest applications in the rapidly emerging field of surface functionalization through LIPSS, including biomimetic functionalities on fluid transport, control of the wetting properties, specific optical responses in technical materials, improvement of tribological performance on metallic surfaces, and bacterial and cell growth for medical devices, among many others.

Published: May 2020

Talas Sumedang (semir) merupakan salah satu komoditas pertanian hortikultura unggulan dan bahan pangan potensial di Kabupaten Sumedang. Namun, saat ini pemanfaatannya masih terbatas. Untuk menjadikannya sebagai bahan baku olahan pangan, maka talas harus dijadikan tepung terlebih dahulu, sehingga lebih tahan lama dan dapat dibuat menjadi aneka produk olahan pangan. Proses pengolahan talas menjadi tepung ada tahapan penting yang harus dilalui yaitu proses pengupasan. Proses pengupasana secara manual memerlukan waktu yang cukup lama serta membutuhkan tenaga kerja yang cukup banyak. Hal ini menjadi kendala apabila kapasitas produksi sudah besar serta berlanjutan (kontinyu). Dengan demikian dibutuhkan peran mekanisasi pertanian untuk mengatasi masalah tersebut yaitu dengan dirancang bangun mesin pengupas talas.Penelitian ini bertujuan untuk merancang bangun mesin pengupas talas talas untuk proses pascapanen dan menjadikannya sebagai bahan pangan alternatif potensial. Penelitian akan dilaksanakan pada bulan April - November 2016 bertempat di Bengkel Logam, Kayu dan Rotan, Laboratorium Alat dan Mesin Pertanian, Departemen Teknik Pertanian dan Biosistem, Fakultas Teknologi Industri Pertanian UNPAD, Jatinangor.Hasil pengujian menunjukkan bahwa mesin bekerja dengan baik dengan kapasitas aktual 78,8 kg/jam, efisensi mesin 78,74%  dan hasil kupasan sudah merata pada semua pemukaan talas namun masih belum bersih karena proses pengupasan belum disertai penyiraman menggunakan air.

Published: May 2020

With the availability of information in the World Wide Web its access and retrieval by the users is facilitated, and the Library and Information Science (LIS) field’s knowledge and techniques can be applied to this environment in order to help with the process. The present study is descriptive, qualitative and exploratory, based on bibliographical sources, in which it was explored how the Classification discipline interacts with Linked Data, focusing on the analysis of Dewey Linked Data. From four catalogs analyzed, referred to in the literature as adhering to Dewey Linked Data, only two actually has links in their records redirecting to the system. Despite this, its presence in The Linked Open Data Cloud appears as a positive factor in its dissemination, since it boosts its visibility. It is concluded that the Classification discipline allows the thematic standardization of information resources, so that there is uniformity in the Web environment and quality retrieval of information, while promoting interoperability between data in the Linked Data context. The standardization of metadata values using classifications optimizes the representation of information and its retrieval in the Web, while also providing the reuse of data. In addition, studies that align the area of Library and Information Science with the Semantic Web and its technologies can provide new perspectives for the area, as well as contemplate the users’ always changing needs, thus, fulfilling the objective of the field.

Published: May 2020

Motorcycles are a type of transportation that is familiar in Indonesia. Cost product and speed for mobilization are the main reasons for choosing this transportation. Demand for motorcycles that are still large in Indonesia and encouraged motorcycles manufacturing industries to deliver products according to consumer needs. To be able to meet the varied needs of consumers, motorcycle manufacturers always make improvements in all of their production area. There are two main components in the motorcycle, engine and frame. These two components are produced by several parts of production based on the characteristics of each product. The production section of the motorcycle industry that do paintingactivities on plastic products is painting plastic section. The coating technology used in painting plastic is atomization . This technology is a converting liquid material into mist or granules used to coat the product. This technology has many challenges in terms of material transfer to products. The selection of the right material is the key to the atomization process, besides that human factors are also important because the operator's competence or expertise during the painting process can affect product yield. From these problems the author tries to map some of the problems caused by paintings, including technological materials, production systems, product quality and problems caused by painting processes to the environment. However with the level of complexity of the problems faced by the plastic paintingsection, not many studies have focused on the problems in the paintingprocess of plastic products. Therefore the author tries to give a detailed description of the production process in the painting plastic section. The author divides this article into several sub-chapters including paintingtechnology, technology material, production system and Quality properties. Furthermore, the authors hope that this article can be used as a basis for developing the paintingprocess on plastic products.

The garbage dumping in Tegal Regency has reached 989.8 m3/day and increasing every year. The percentage of waste in Murareja landfill is dominated by plastic waste which is 40.15%. The plastic waste will be processed by pyrolysis by utilizing Refuse Derived Fuel (RDF) as its fuel. The percentage of garbage in Murareja TPA that can be used as RDF is quite high, which is 28.7%, consisting of 15.35% paper waste, 2.35% rubber / leather waste, 2% garbage cloth, 1% wood waste, and 8% plastic waste. The waste is considered potentially to be produced into RDF. The production of RDF aims to convert the combustible waste fraction from 4K1P waste (Paper, Wood, Fabrics, Rubber / Leather and Plastics) to be fueled. Therefore it is important to know how much potential of 4K1P waste to be processed into RDF, and how optimal calorific value of RDF is to be used as fuel of pyrolysis incinerator on Waste Power Generation at Murareja TPA, Tegal regency. Based on the result of the research that has been done, the theoretical value of the theoretical value of 4K1P RDF briquette is 3677.0945 - 5507.114 [kcal / kg]. From the actual data obtained with laboratory testing the value of RDF beverage caloric waste 4K1P RDF amounted to 3973.45 [kCal / kg]. The optimal calorific value of RDF required as a pyrolysis incinerator fuel is 3248.809 [kcal / kg]. Based on the results of laboratory tests, the percentage of moisture content, ash content, volatile content and carbon content are 4.68%, 11.64%, 7.81% and 75.87% respectively.

The vehicle market in Indonesia, especially motorbikes is very large, it is estimated that the growth of motorbike vehicles will reach 6 million per year. Recently, more than 50 percent is dominated by automatic motorcycles and the market increase significantly. This is because automatic motorcycles can be easily ridden. There are some weaknesses with this transmission system, among them is there is no engine brake when the road is in downhill condition. The motor will easily run when the gas throttle is pressed. This paper discusses the design of a mechanical system on the automatic transmission that is able to prevent mistake on procedures that causes accidents. To achieve this goal, it is necessary to do several steps, including reviewing the existing design, determining the new system, designing the system, manufactured and testing. Experiment results shows that the current motorcycles automatic transmission system can be replaced with a mechatronic system with special linkage mechanism to control ratio change.

The number of vehicles has increased every year. This increase was accompanied by an increase in the number of accidents that occurred. Accidents that occur result in damage to vehicles so that repainting is needed. Painting is an effort made by applying paint in liquid form on the surface of an object to create a layer on the surface of the object. Painting serves to protect and improve the appearance of a surface. The purpose of this study is to determine the effect of a combination of parameters that can produce maximum thickness values. The experimental design used in this study is a surface response method with three parameters where each parameter has three levels. The parameters chosen were spraying distance (110 mm, 130 mm, 150 mm), composition between paint-thinner (1/1.6, 1/1.4, 1/1.2), and pressure (3.5, 4.5, 5.5). The painting process is carried out with the help of a paint test demonstrator. The painting results are dried in the oven and then measured using a thickness gauge. The measurement data is processed using the help of Minitab software and the estimator equation for thickness is obtained. The parameters with the greatest influence in this study are the distance of spraying with a distance coefficient of 2.258. Painting with the highest average value of thickness occurred in the fifteenth experiment with a thickness value of 39.9 micron. The thickness is obtained by variable variations of 130 mm distance, paint-thinner 1/1.4 composition and 4.5 bar pressure.

The purpose of this phenomenological study was to explore the orientation and transitional experiences of Black undergraduate students at Metropolitan State University (MSU, pseudonym) an urban, public research university in the southeastern region of the United States. MSU is a unique research site for this study, as Black students’ six-year graduation rates equal that of White students. Using sense of belonging as a conceptual framework, the research team collected data from 28 participants in seven focus groups throughout the 2018-2019 academic year.  Findings revealed that participants experienced disparate orientation and transitional experiences, as well as a poor racial climate throughout their time at MSU.  Specifically, participants noted a shortage of Black faculty, limited Black cultural programming, and a need for identity-based space. Among working with campus partners to improve the racial climate, implications for orientation professionals include recruiting professional and student staff members who represent the racial composition of the university and ensuring culturally relevant content during orientation programs.

The Impact of an Online Orientation Program on Student Success at a Community College
Authors: Lerner Colucci Rachel
Published: May 2020

This study examined the effectiveness of an online orientation program on participation and student success for a defined cohort of students at a mid-size community college in the mid-Atlantic region. Specifically, a quantitative analysis focused on differences in grade point average (GPA) and retention as success factors among students who completed the online orientation versus students who only started but did not finish and students who did not attempt the program at all. 

The findings indicate a statistically significant difference in fall to spring retention and cumulative GPA earned after the first semester for students who complete the online orientation module over students who access but do not complete and students who do not access the program. Further, follow-up survey data indicate students felt more prepared to attend the college and utilize programs and services after completing the program.

The study contributes to the research and literature on online orientation programs, specifically in the community college setting, and the researchers offers a discussion of results and recommendations for policy, practice, and future research.
