A Study of Using E-Writing Instructional Design Program to Develop English Writing Ability of Thai EFL Learners
Authors: Kawinkoonlasate Pongpatchara 
Published: May 2021

Learning with technology has become essential in today&rsquo;s education not only in Thailand but also all around the world. Technology has been an important tool for improving language learners&rsquo; reading writing, speaking, and listening for quite some time. Writing, however, has been one of the most supported skills thanks to technology. Learning how to write paragraphs or essays is an essential skill for learners. The purposes of this quasi-experimental study were:&nbsp;
1) to examine the effectiveness of the e-Writing instructional design program in developing the writing skills of EFL learners, 2) to explore learners&rsquo; satisfaction and motivation toward the e-Writing instructional design program, and 3) to study learners&rsquo; autonomy after completing the e-Writing instructional design program. This study employed the purposive sampling method to select 33 second-year learners. Lesson plans, e-writing programs, learner perception questionnaires, interviews, as well as a pre and post-test were the tools used to gather relevant data. A t-test with standard and average deviation was used to investigate the quantitative data.
Interview data were analyzed using content analysis. The quantitative findings revealed that the writing achievement level of the learners before and after receiving the treatment was significantly different at 0.001. The learners&rsquo; post-test scores of 33 learners increased over the pre-test scores. From the questionnaire results, the satisfaction level of undergraduate learners toward the instruction of this course had average scores of 4.34 which was an excellent level.&nbsp;
Furthermore, interviews revealed that learners are satisfied with the e-Writing instructional design program because this could improve learners&rsquo; writing skills and promote more learner autonomy. Recommendations are made and presented in terms of future practical application and future research needs to be done to analyze results and the effects of future outcomes.
A Time-Domain Simulation for Predicting the Downwind Performance of Yachts in Waves
Authors: Harris Dougal , Thomas Giles , Renilson Martin 
Published: May 2021

Yachts racing in many of today's high profile races, such as the America's Cup and the Volvo Ocean Race, spend much time sailing downwind in following seas. The development of a method for predicting the performance of yachts sailing downwind in waves would therefore provide a valuable design tool for racing yacht designers.
This paper describes the development of a time­domain simulation for predicting the performance of yachts sailing in irregular seas for apparent wind angles between 90 and 180 degrees. The simulation output may be used to either directly compare different designs or augment existing polar plots for the effect of a following sea.
The simulation is comprised of three main modules: the wave induced longitudinal force, the resistance force and the sail aerodynamic force. The resistance and wave force modules have been validated through semi-captive model experiments. Results from the complete simulation have been compared with those obtained from free running model experiments.
Numerical experiments on a number of hull and rig configurations have been conducted using the simulation. Results are presented with conclusions being drawn on the effect of hull form and environmental conditions on downwind performance.
Aerodynamic Performance of Offwind Sails Attached to Sprits
Authors: Ranzenbach Robert , Teeters Jim 
Published: May 2021

The primary purpose of this offwind sail investigation was to better understand the relative performance of symmetric spinnakers flown from conventional poles and asymmetric spinnakers flown from conventional poles or sprits, i.e. poles restricted to the centerline.
The specific goal was to improve the aerodynamic modeling of offwind sails used in the International Measurement System (IMS) handicapping formula to address perceived inequities in their performance potential, particularly when running at very deep angles.
Running style offwind sails of varying size, type, and pole configuration were evaluated over appropriate ranges of angle of attack and trim settings. Improved performance coefficients were developed from this data for inclusion into the 2001 IMS velocity prediction program.
Realidad aumentada y estimulación de la competencia socio-comunicativa en sujetos con TEA
Authors: Del Moral Pérez María Esther , López-Bouzas Nerea 
Published: May 2021

Se recogen estudios centrados en analizar el impacto de la realidad aumentada (RA) en intervenciones con sujetos con Trastorno del Espectro Autista (TEA), orientados a estimular sus competencias social y comunicativa, favoreciendo su interacción social. Se adopta una metodología cualitativa, concretada en la revisión sistemática de investigaciones (N=26) -a través de meta-análisis-, publicadas durante 2012-2020 en revistas de impacto, desarrolladas en tres contextos: educativo, experimental-psicológico y tecnológico. Los resultados reflejan que en su mayoría son estudios de caso. Destacan los estudios de índole tecnológico, ligados al diseño e implementación de recursos con RA en ámbito clínico. Asimismo, los asociados a intervenciones en contextos educativos incorporan la RA como recursos didácticos en ámbitos escolares. Los desarrollados en contextos experimentales-psicológicos describen intervenciones con RA y analizan el comportamiento de los sujetos en diversos ámbitos. Se observa unanimidad al subrayar el impacto positivo de las app o sistemas de RA para estimular la interacción social. Sin embargo, no especifican las fases de intervención ni utilizan app o recursos comerciales o accesibles, limitando su extrapolación a otros contextos. Concluyendo, se precisan equipos interdisciplinares que compartan hallazgos que redunden en beneficio de los sujetos con TEA, suscitando intervenciones que favorezcan su plena inclusión socio-educativa.
Some studies, focused on analysing the impact of augmented reality in interventions to people with Autism Spectrum Disorder (ASD), are gathered, directed to stimulate their social and communicative abilities in order to favour their social interaction. A qualitative methodology is adopted in this paper as specified in the systematic revision of investigations (N=26) -through meta-analysis- published during 2012-2020 in specialized academic journals and developed in three different contexts: educative, technological and psycho-experimental. The results show that most of them are case studies. Technological studies, bound to the design and establishment of augmented reality resources in the clinical setting, are the ones that stand out. Furthermore, those associated to interventions in the educational environment incorporate augmented reality as a teaching resource in the school setting. Finally, those developed in a psycho-experimental context describe interventions with augmented reality and analyse the people’s behaviour in different fields. Unanimity is observed when it comes to highlight the positive impact these apps or augmented reality systems have to stimulate social interaction. However, interventions phases are not specified nor are accessible or commercial resources used, what restricts its extrapolation to other contexts. In conclusion, an interdisciplinary equipment which shares the discoveries concerning the benefit of people with ASD is required, arousing interventions which favour their total socio-educational inclusion.
MATHEMATICAL AND STATISTICAL MODEL OF CLEANING IN A HIGH-GRADIENT MAGNETIC FIELD OF HYDROGENATED FAT FROM SUSPENDED CATALYST
Authors: Tyrtygin Vyacheslav N. , Deniskovets Aleksey A. , Labutin Aleksandr N. 
Published: May 2021

The introduction specifies the object of the study - hydrogenated fat subjected to purification from suspended nickel-containing catalyst in a high-gradient magnetic field. The nickel-containing catalyst, due to the presence of nickel salts in it, is paramagnetic and can be effectively extracted from hydrated fat in the magnetic field by a method of highly gradient magnetic separation. In the experiment technique the magnetic field strength was not less than 600 kA/m, the gradient not less than (20-30)∙104 kA/m2. Based on the results and their discussion, the analysis of empirical dependencies on each factor basis is carried out separately, as well as the construction of classical types of one-dimensional non-linear regression models for each of them. It is shown that the most statistically reliable are the exponential models. It was found that after purification the content of suspended nickel-containing catalyst in the hydrogenated fat has an inverse proportional dependence on the magnetic field strength, height (length) of the filtration zone and filtration rate. A two-dimensional exponential regression model of the content of the nickel-containing catalyst in the hydrogenated fat in the complex dependence on the rate and height of the filtration zone is built. Based on the experimental data at a certain height of the filtration zone and the selected filtration rate, a mathematical-statistical model of change in the concentration of nickel-containing catalyst depending on the magnetic field strength is made. Using the resulting two-dimensional exponential regression model, it is possible to predict the degree of purification of the salomas from the suspended catalyst depending on the specific tension of the magnetic field and to determine the tension of the magnetic field, at which the concentration of nickel as a result of cleaning will reach an advance value.

Authors: Hermawan Stepanus Maman , Wihardja Hany 
Published: May 2021

Cerebrovascular accident (CVA) is a neurological deficit condition caused by an acute focal injury of the central nervous system by cerebral infarction or intracerebral hemorrhage. CVA patients who do not reduce risk factors after the first attack have an 8.7 times higher risk of CVA recurrence. The effect of a recurrent CVA is six times greater than the risk of a first CVA in the general population of the same age and sex, and nearly half of them remain alive but are physically disabled. This case report illustrates the process of recurrent CVA and disability experienced by a 69-year-old Malay woman, a patient at a private hospital in West Kalimantan. The nursing strategy of two post-CVA physical rehabilitation exercise programs for patients during hospitalization will be explained according to the stages in nursing theory.Abstrak Mengejar Kebutuhan Aktivitas Fisik Pasien CVA Berulang Selama Hospitalisasi: Laporan Kasus.

Published: May 2021

This study examined breastfeeding practices and self-efficacy among mothers residing in rural areas. A cross-sectional study was conducted for 104 mothers via purposeful sampling in a Posyandu (maternal and child health service) in Kampar district, one of the rural areas in Riau, Indonesia. The Breastfeeding Self-Efficacy Scale Short Form (BSES-SF) was used in the questionnaires to collect data. Chi-square test was used for bivariate analysis. Majority of the respondents (71.2%) were 20–35 years old; 69.3% of the respondents’ level of education were low (such as junior and senior high school levels). Approximately 91.3% of them were housewives. Exclusive breastfeeding prevalence was only 30.8%, with insufficient milk being the most common reasons cited by the mothers as failure to breastfeed exclusively. Porridge and mineral water were the most commonly supplied food given to babies under 6 months among 31.7% and 36.5% mothers, respectively. The respondents faced some breast problems, where 72.1% mothers did not have good breastfeeding skills. Approximately 59.6% mothers had higher breastfeeding self-efficacy than the mean score for BSES-SF, which was 58.58 (11.58 standard deviation [SD]). Mothers’ age was significantly correlated with the BSES among mothers (p < 0.01). Increasing young mother’s breastfeeding self-efficacy during the antenatal care period is important to lower these young mothers’ perception of having insufficient milk. Abstrak Praktik Menyusui dan Efikasi Diri Ibu. Penelitian ini bertujuan untuk menggambarkan tentang praktik pemberian air susu ibu (ASI) dan efikasi diri ibu menyusui di daerah pedesaan. Penelitian ini menggunakan pendekatan cross sectional pada 104 ibu yang berkunjung ke Posyandu sebagai tempat pos kesehatan untuk ibu dan anak yang diambil menggunakan teknik purposeful sampling.

Published: May 2021

Men who have sex with men (MSM) comprise a population at risk for HIV infection. Assessing the Quality of Life (QOL) in MSM might be different than other populations. This study showed a secondary analysis from our previous research. It was needed to understand whether peer support and family acceptance had an impact on QOL of MSM living with HIV and ART (Antiretroviral Therapy). A total of 175 respondents were involved in this cross-sectional study that was carried out with purposive sampling. The questionnaires were translated to Bahasa and tested for validity and reliability. Data questionnaires completed were analyzed. Results showed that peer support was positively correlated with QOL (p= 0.023; OR= 2.070), and also, family acceptance was significantly related to QOL (p= 0.001; OR= 2.766). Thus, peer support and family acceptance are important factors affecting the well-being and QOL of MSM living with HIV and ART. This finding can be used for the improvement of QOL in people living with HIV.

Fish skin, a sustainable material used from ancient times to today's fashion
Authors: Rahme Lotta 
Published: May 2021

The use of fish skin is an ancient tradition in Arctic societies along rivers, streams and coasts all over the world. Fish skins were regarded as a useful material for parkas, boots, mittens and hats. Today the interest in making use of fish skin, an undeveloped by-product, is on the rise. By using different tanning techniques from cultures around the globe, fish skin has shown great promise as a material for clothing, as well as other products. There is also a desire to be able to tan these skins with environmentally friendly techniques. Today most animal skins are tanned using chromium and other cheap toxic substances, raising question around health and environmental safety. The knowledge of how to use these traditional tanning methods has been preserved by woman from cultures along the Arctic Circle stretching from the Nordic countries to Canada and Japan. In order to keep this knowledge alive for future generations, Sweden has re-introduced the possibility to receive a Master tanner´s title, increasing the incentive and status for those studying these important subjects. This is a report and narrative review of the field, and insights I have acquired over 3 decades; from student to Master Tanner.
Patterned Silk Weaving in Ancient Times
Authors: Eriksen Åse 
Published: May 2021

Patterned silks came to Scandinavia as small pieces of reused material, but they were still valuable for the Vikings to have been used as trimmings on their garments. In over a millennium, the weave structure of samitum in these fragments was used in all patterned silk. In the medieval it was displaced in favor for other structures. It has lapsed into obscurity for weavers today. For several reasons the study of these silks has been difficult. The fragments are fragile. They were not made in Norway. Few have mastered this weaving technique. Is it possible to reconstruct these ancient silks, based on the knowledge gained from studying historical silks and experience acquired from using the structure in modern textiles? This article is about my attempt to do so, and also my reflections of the possible longtime impact on these silks on the weaving tradition in Norway.
High glucose treatment promotes extracellular matrix proteome remodeling in Müller glial cells

Published: May 2021

Background
The underlying pathomechanisms in diabetic retinopathy (DR) remain incompletely understood. The aim of this study was to add to the current knowledge about the particular role of retinal Müller glial cells (RMG) in the initial processes of DR.

Methods
Applying a quantitative proteomic workflow, we investigated changes of primary porcine RMG under short term high glucose treatment as well as glycolysis inhibition treatment.

Results
We revealed significant changes in RMG proteome primarily in proteins building the extracellular matrix (ECM) indicating fundamental remodeling processes of ECM as novel rapid response to high glucose treatment. Among others, Osteopontin (SPP1) as well as its interacting integrins were significantly downregulated and organotypic retinal explant culture confirmed the selective loss of SPP1 in RMG upon treatment. Since SPP1 in the retina has been described neuroprotective for photoreceptors and functions against experimentally induced cell swelling, it’s rapid loss under diabetic conditions may point to a direct involvement of RMG to the early neurodegenerative processes driving DR.

Circulating Level of Soluble Leptin Receptor and its Association with Cardiometabolic Risk Factors among Obese Subjects in Kerala, South India
Authors: Manju K. S. , Leena K. B. , Vijayalekshmi L. , Shenoy K. T. 
Published: May 2021

Background and Aims: Leptin, the peptide hormone secreted mainly by adipose tissue is reported to play the central role in the pathogenesis of obesity. Leptin exerts its biological effects through specific receptor molecules present in target tissues. Among the different isoforms of leptin receptor, the Soluble Leptin Receptor (SLR) is the major leptin binding protein seen in circulation which modulates the bioavailability of leptin. Our objectives were to analyse the level of circulating SLR among obese subjects and its association with biomarkers of obesity, serum leptin, insulin and cardiometabolic risk factors in comparison with healthy age and sex matched control subjects.
Methods: About 173 study participants of both genders were selected and grouped as case (n=102) and control (n=71) with a cut off point of BMI 25kg/m2. Waist to hip ratio (WHR) and body fat percentage (BF%) were calculated from anthropometric measurements. Leptin, insulin, soluble leptin receptor were estimated in fasting blood samples by sandwich ELISA method. Fasting plasma glucose and lipid profile were measured by standard enzymatic methods in autoanalyzer. Homeostasis Model Assessment of Insulin resistance (HOMA-IR) was calculated. Comparison between groups was done by independent sample ‘t’ test. P values <.05 were considered statistically significant.
Results: The SLR level was found to be increased in obese group in comparison with control group(P =.001). A significant increase in serum leptin and insulin level was observed in obese group when compared to control (P =.001). Obese group showed more than two fold increase in insulin resistance expressed as HOMA-IR when compared to control subjects (P =.001). But no significant difference in the synthesis of insulin expressed as HOMA-beta between the groups. No significant difference in serum lipoprotein levels was observed between the two groups.
Conclusion: Increased level of circulating soluble leptin receptor has been observed in obese subjects in comparison with control subjects and is associated with hyperleptinemia, hypertension and insulin resistance.
