EFEKTIVITAS MODEL CREATIVE PROBLEM SOLVING BERBASIS APLIKASI BIT.LY DALAM PEMBELAJARAN FISIKA
Authors: Juliansyah Asep Ilham , Nana
Published: March 2020

This research uses the bit.ly application as a medium in learning strategies using virtual simulations aimed at increasing students' mastery and understanding in understanding a material. The purpose of this research is motivated by the lack of mastery of the material so that the learning applied is not yet maximal, because it is necessary for innovation in learning by applying the creative problem solving model based on bit.ly application. Creative problem solving model as a problem solving process is accompanied by the use of bit.ly applications so that students are motivated in learning and can improve their learning outcomes and also hone the creativity of a teacher. The method used in this paper is literature study by examining some literature to be analyzed and made conclusions. the results of this study prove that the application of a creative problem solving model based on bit.ly applications as learning innovations can be one of the solutions to problems encountered in the teaching and learning process in the classroom and also facilitate the teacher in delivering a material. The creative problem solving model is applied in high school with several steps: students clarify various problems to solve, then emphasize to better understand students using the bit.ly application. Creative problem solving learning that uses the bit.ly application can activate the creativity of teachers and students so that students become more active in learning. Therefore, the need for a teacher's readiness to always innovate in providing material and also the readiness of a student to accept all forms of innovation.
Segmentation of Potato Consumers Based on Sensory and Attitudinal Aspects
Authors: Sharma Chetan
Published: March 2020

Consumer hedonic scores for potatoes were linked to sensory characteristics to understand the underlying consumer segments, flavor and texture preferences and attitudinal associations regarding potatoes. Consumers were asked to evaluate liking on a 9-point hedonic scale for 12 cultivars of potatoes. Sensory findings were collected by using a consensus-based descriptive analysis approach for the same cultivars. Segmentation analysis procedure identified three subgroups of consumers with different overall liking patterns, indicating variability in the acceptance of different potato cultivars. Drivers of liking were identified for respective segments by using preference mapping. Dissimilar features were found important in determining potato liking patterns. Purple Majesty, Masquerade and Rio Colorado cultivars were found most liked by respondents, while Russian Banana were found to be liked the least. Tuber color, price, variety name on package, color of peel, and being locally produced were found to be important factors in purchasing decisions.
Self-control moderates the association between perceived severity of the coronavirus disease 2019 (COVID-19) and mental health problems among the Chinese public

Published: March 2020

The coronavirus disease 2019 (COVID-19) has caused thousands of death in China. Prior research suggests that individuals’ perceived severity of the COVID-19 is related to a range of negative emotional and behavioural reactions among the Chinese public. However, scant research has examined the underlying mechanisms. Drawing upon the risk-resilience model, this study proposes that self-control, as a resilient factor, would potentially moderate the association between perceived severity of the COVID-19 and mental health problems. Data from a national survey was used to examine this possibility. Participants were 4,607 citizens from 31 regions in China (Mage=23.71 years, 72.5% female) who completed a national survey at the beginning of February 2020. Results of hierarchical regression showed that after controlling for demographic variables, perceived severity of the COVID-19 and self-control were positively and negatively related to mental health problems, respectively. More importantly, self-control moderated the “perceived severity of the COVID-19 – mental health problems” association, with the said link attenuating as the levels of self-control increased. These findings suggest that compared to those with high self-control, individuals with low self-control are more vulnerable and are more in need of psychological aids to maintain mental health in the encounter of the COVID-19 outbreak.
Neural representations of awe: Distinguishing common and distinct neural mechanisms
Authors: Takano Ryota , Nomura Michio
Published: March 2020

Awe is an emotional response to perceptually vast stimuli that transcend one’s current frames of reference. The psychological form and function of awe differ between two types: positive-awe, which arises from the beauty of nature, and threat-awe, which is inspired by natural disasters. However, little is known about the neural bases underlying these types of awe. Here, using functional magnetic resonance imaging, we investigated common and distinct neural responses to experiences of positive- and threat-awe, elicited by watching awe-inspiring videos. We found that both awe experiences deactivated the left middle temporal gyrus (MTG) compared to control conditions (positive-awe vs. amusement; threat-awe vs. fear). In addition, positive-awe was associated with increased functional connectivity between the MTG and the cingulate cortex and supramarginal gyrus (SMG), and threat-awe was associated with increased functional connectivity between the MTG and amygdala, as well as between the amygdala and SMG. These findings suggest that the neural mechanisms underlying the complex psychological processes of awe vary as a function of the type of awe. The implications of these results regarding our understanding of the neural basis of awe and the future directions of human social cognition research are discussed.
On the limits of shared syntactic representations: When word order variation blocks priming between an artificial language and Dutch
Authors: Muylle Merel , Sarah Bernolet , Hartsuiker Robert
Published: March 2020

Several studies used artificial language (AL) learning paradigms to investigate structural priming between languages in early phases of learning. The presence of such priming would indicate that syntactic representations are shared across these languages. Muylle, Bernolet, and Hartsuiker (2020) found similar priming between Dutch (SVO order) and an AL with either SVO or SOV order. However, it is unclear whether such sharing would occur if the AL allows both the same and different word order as the native language. Indeed, the presence of a (easy to share) similar structure might block the sharing of a less similar structure. Here, we report two experiments that each tested 48 native speakers of Dutch on an AL that allowed both SVO and SOV order in transitive and ditransitive sentences. We assessed both within- AL and AL-Dutch priming. We predicted a) priming of both structure and word order within the AL, and b) that the presence of SVO sentences in the AL would result in weaker priming to Dutch from SOV sentences than from SVO sentences. Indeed, cross-linguistic priming was significantly weaker in the SOV compared to the SVO conditions, in line with our predictions. Unexpectedly, in the absence of a condition with verb overlap between prime and target sentences, no priming was found in AL and Dutch target conditions without verb overlap (Experiment 1), but priming emerged when a verb overlap condition was added (Experiment 2). This finding suggests that lexical overlap conditions are crucial to establish abstract syntactic representations during early L2 acquisition.

Background and Aims: Use of point-of-care ultrasound (POCUS) in acute care setting has rapidly increased and has potentials to guide patient management. This survey study aims to explore the usefulness of a one-day workshop and to elicit the perceived barriers for effective use of POCUS.

Methods: A total of 169 doctors who had attended one day Acute Care Ultrasound workshop were approached through email. Online link to access the survey created using Google forms was sent. The survey contained questions related to the details about the participants, feedback about the workshop, whether the workshop has helped to change the practice of the participants, availability of ultrasound machine during the daily practice and the perceived barriers for use of POCUS.

Results: A total of 41 responses were obtained. Majority of the participants had anaesthesiology as the base specialty followed by general practice. Most of them had ICU as their predominant working place, followed by emergency room and operating room. The workshop was found to be helpful by most of the participants. Majority of the participants (20 participants; 49%) had ultrasound machine sometimes available during their daily practice. Only 20% (8 participants) had ultrasound machine always available during their clinical practice. Similarly, 46% (19 participants) considered lack of access to ultrasound machine as a barrier for application of POCUS. Significant number of participants considered lack of supervision and guidance (18 participants; 44%) and lack of knowledge and skills (13 participants; 32%) as the barriers.

Conclusions: Majority of the participants found the one-day workshop helpful. Doctors from various specialty, working in acute care setting had participated in the survey. Limited access to ultrasound machine, together with lack of adequate knowledge and skills were perceived as major barriers for effective use of point-of-care ultrasound.

Authors: Ezzat A.
Published: March 2020

The study aimed to find the effect of different maturity classes (up to the days after full blossom) on the post-harvest life of 3 different apricot varieties Gold Cot, Bergarouge and Flavor Cot in Hungary. The fruit harvested in a particular time 65, 75 and 85 days after full blossom and divided to three maturity classes (Class 1, 2 and 3, respectively). Fruit stored in cold storage for 7 days at temperature 1 °C. Fruits were investigated in regard to physical parameters (weight loss, fruit firmness and soluble solid content SSC) and chilling injuries. The results showed that the varieties followed different ways in regard to response to different maturity classes. The maturity class I for all the tested varieties recorded the lowest weight loss, while with the increasing maturity stage the weight loss percentage for all the varieties recoded high values. The firmness decreased with delayed harvesting for all the varieties. Data of the chilling injuries showed that all the fruits which harvested at maturity I, recorded the highest percentage of fruit with CI (chilling injuries) at 0 (48.5, 37.25 and 38.75%) and CI class I (44.75, 35.75 and 39.75%) for Bergarouge, Gold Cot, and Flavor Cot.

Roads Old and New: Educational Strategies in University Choice by Russian Students
Authors: Skalaban I. A. , Osmuk L. A. , Kolesova O. V. , Cherepanov G. M.
Published: March 2020

This paper aims to explore the capabilities of new approaches to the study of educational demands on modern higher education market by describing existing educational strategies of applicants and students. The experience of university choice research in domestic and international practice consists of sufficiently popular description of educational demands, choice motivation and analysis of the choice-making process of university and specialty choice based on available information. The analysis of choice presented in the article is compounded by the description of the main educational strategies being formed on modern educational market, with an emphasis on their behavioral nature. Two following strategies are singled out: “status strategy”, where education acts primarily as an element of status and group identification; and “practical strategy” where education is viewed as an investment of time and resources into increasing one’s chances at the job market. Data gathered from the study of students of five universities of Tomsk and Novosibirsk aligns with these strategies, and this justifies the existence of an increasing divide in social-economic demography of higher education. Such tendency is capable of seriously affecting organizational strategies of universities and influence the very nature of higher education as a social institution by forcing universities and the system in general to take the given strategies into account.

The aim of study was to evaluate the mineral changes caused by enamel bleaching treatments at different application times by scanning electron microscope- energy dispersive X-Ray (SEM-EDX). In this study, 36 teeth were divided into 3 groups after mineral measurements (Flour, Silicon, Aluminum, Strontium) with SEM-EDX (n ₌ 12). 40% hydrogen peroxide gel was used for bleaching in all groups. Bleaching was performed 20 min for Group 1, 40 min for Group 2, 60 min for Group 3. Mineral measurements were performed with SEM-EDX after treatment. In the intra-group comparison, although there was no significant difference between Flour (F) and Silicon (Si) values (p ˃ 0.05), there was statistically significant difference in Aluminum (Al) and Strontium (Sr) values (p < 0.05). After the bleaching process for different application times, mineral change was observed in time-depending comparison. The best results were obtained for Group 2, appling according to manufacturer's instructions.

Stavovi roditelja i razrednika o oblicima, učincima i teškoćama partnerskih odnosa između obitelji i škole
Authors: Knežević Mirjana
Published: March 2020

Obitelj i odgojno-obrazovne ustanove dominantna su okruženja djeteta i zato je njihovo partnerstvo prijeko potrebno. Dok suradnja podrazumijeva
pokušaj zadovoljavanja interesa obiju strana, pojam partnerstva, koji se danas sve više koristi, ističe ravnopravnost strana i toleranciju. U literaturi se ističu određeni učinci toga partnerstva kao što su bolji akademski uspjeh djece, bolji odnos djece prema školi te učiteljima i nastavnicima, osnaživanje obitelji te rasterećenje djece. U empirijskom dijelu cilj je bio utvrditi koji oblik odnosa, tradicionalni ili partnerski, njeguju roditelji i razrednici, vide li prednosti partnerskoga odnosa za djecu, odnosno učenike te ispitati njihove stavove o teškoćama ostvarenja partnerskoga odnosa. Istraživanje
na uzorku od 72 roditelja i 18 razrednika provedeno je tijekom rujna i listopada 2017. u Ugostiteljsko-turističkoj školi u Osijeku. Pri provedbi istraživanja koristio se postupak anketiranja. Podatci istraživanja obrađeni su deskriptivnom statistikom, prikazani su grafički i tablično i interpretirani su. Dobiveni rezultati pokazuju kako, unatoč teorijskom zagovaranju partnerskoga odnosa, roditelji i razrednici i dalje prakticiraju tradicionalan odnos iako obje skupine uzorka vide prednosti partnerskoga odnosa za djecu/učenike. Također, razrednici smatraju kako roditelji surađuju sa školom samo kada je to neophodno za daljnje obrazovanje njihova djeteta. Ispitivanjem stavova roditelja i razrednika utvrđeno je kako ne uočavaju teškoće partnerskih odnosa.

je sudjelovalo 421 učenika srednje škole u dobi od 16 do 19 godina. Za ispitivanje dimenzija ličnosti korištena je adaptirana verzija Petofaktorskog inventara ličnosti. Školski uspjeh mjeren je ocjenom općeg uspjeha na kraju školske godine, a ocjena vladanja mjerila se na temelju neopravdanih sati. Glavna analiza podataka uključivala je dvije hijerarhijske regresijske analize u svakoj vremenskoj točki. U oba mjerenja rod je značajno doprinio objašnjenju uspjeha u školi i vladanja. Konkretno, učenice su pokazale bolji uspjeh u školi te bolje vladanje u usporedbi s učenicima. Nadalje, u prvome mjerenju, osobe s izraženim dimenzijama ličnosti i otvorenosti prema iskustvu, savjesnosti
te manje izraženim neuroticizmom pokazale su bolji uspjeh u školi u usporedi s osobama s manje izraženom otvorenosti prema iskustvu, savjesnosti te više izraženim neuroticizmom. Međutim, petofaktorske dimenzije ličnosti u drugom mjerenju nisu značajno dodatno objasnile uspjeh u školi i vladanje. Rezultati ističu utjecaj pojedinih osobina ličnosti na opći uspjeh i vladanje u srednjoj školi u dvama mjerenjima.

This article examines and analyzes the basic directions of development and improvement of the system of manning of the Armed Forces of Ukraine with the sergeants (and other enlisted grades) , based on the experience gained and on analysis of manning systems of the leading countries of the world. In Ukraine, with the onset of the armed aggression of the Russian Federation, the tasks assigned to the personnel services and military commissariats required rapid response and aimed at implementing mobilization deployment of the Armed Forces of Ukraine.

To date, the main focus on staffing the Armed Forces of Ukraine is the priority of providing operational (tactical) grouping of troops to contracted military servicemen to accomplish tasks during the operation of the Joint Forces and further readiness of the troops (forces) to repel the armed aggression. At the same time, an important issue to resolve is the recruitment of a professional sergeant (and other enlisted grades) for the military service, with the encouragement of military personnel to prolong their military service. The article describes the reasons that may deter citizens from joining the military service and ways to resolve this issue.

Particular attention in the article is devoted to the work of recruiting units, which provide selection for contracted military service using the latest selection technologies and techniques. The importance of the practical activity of the territorial recruitment and social support centers for the instructors of the recruiting and recruitment departments is also considered.

Endometrial cancer is one of the most frequent gynecological malignancies present in more than 95 % of all uterine cancers. In spite of that, screening of such disease is not commonly performed in clinical practice due to enormous costs and relatively low sensitivity. Therefore, developing an effective screening test to diagnose endometrial cancer at early stages is of great importance for the clinical area of investigation. In this work, we applied urinary proteomics (i.e., bottom-up proteomic approach followed by nano HPLC-ESI-MS/MS) in patients with endometrial cancer, with respect to find proteins aimed for the early diagnostics and screening. According to the results, the significant semi-quantitative changes were observed in urinary proteome of treated patients. The proteins that may be pivotal in pathogenesis of endometrial cancer, like cadherin-1 (CDH1), vitronectin (VTN) and basement membrane specific-heparan sulphate proteoglycan core protein (HSPG2) were down-regulated, when compared to the control group. Ultimately, it can be stated that urinary proteomics has a potential for the searching of cancer protein biomarkers based on their altered concentration.

Transcranial electric stimulation (tES) protocols strictly need to keep the safety of stimulations and to avoid the unpleasant feelings of stimulated subjects. Following that, the aim of the paper was to find out both the perception and the pain thresholds of different tES modalities. The perception thresholds and the pain thresholds at AF7 and AF8 electrodes with transcranial direct and alternating current stimulation (tDCS and tACS) were performed. Average perception and pain thresholds did not differ significantly inter-individually but intra-individually. With gradually increasing intensity the analysis of thresholds showed that 1) an average participant perceived as first 20 Hz and 40 Hz tACS, then 10 Hz tACS and cathodal tDCS and then anodal tDCS, and 2) the pain was felt first for anodal tDCS, then for 6, 10 and 20 Hz tACS, then for cathodal tDCS and finally for 40 Hz tACS. Besides that, intensity-dependent regularities in feelings of different tES modalities were found. Perception thresholds for 2 types of tDCS (anodal and cathodal) and 4 types of tACS (6-40 Hz) are arranged in sequence of gradually increased values (threshold current): anodal tDCS – cathodal tDCS – 6 – 10 – 20 – 40 Hz tACS. whereas pain thresholds are arranged with decreased threshold values.

Published: March 2020

Nanofiber scaffolds provide numerous advantages over common carriers engineered for microorganisms. The most important advantage is an increased speed of primary surface colonization (up to four times faster), which shortens the time required for the areal biofilm formation and optimum performance of attached microorganisms (higher efficiency of biological activity of up to twice as fast). Image analysis predicts early formation of biofilm even in beginning stages; analysis of biofilm reveals the different structures of bacterial colonies on both scaffolds (higher porosity, size, and number of bacterial colonies on nanofiber’s surface). The image analysis correlates well with determinations of dry matter (linear correlation of 0.96) and proteins (linear correlation of 0.89).

Based on their field of application, the physical parameters of shock waves differ. Experiments referred to in this article used tandem shock waves generated on the surface of a composite anode. There, individual pores of the anode produce multichannel discharges. The composite anode may have a variety of shapes, which, consequently, influence the arrangement of the entire apparatus and the area of their application. Experiments referred to in this article utilise an anode divided into two parts that generated tandem shock waves. The previously conducted experiments have clearly shown that the effect of a tandem shock wave can be very well localized in the focal area, causing necrosis and apoptosis of the tumor cells, and enhancing the effect of cytostatics. This study investigated the effect of tandem shock waves with concomitantly administered cytostatics. We conducted our experiments on Lewis rats. The rats were injected with syngeneic sarcoma tumor cells intradermally and caudally on both the right and left sides. The highest rate of tumor growth inhibition was observed in the cisplatin-treated group that was subsequently treated with shock waves. The effect of shock waves on cell membranes is well described as they increase their permeability due to sonodynamic effect induced by cavitation. The results of experiments referred to in this article conducted in vivo in experimental animals enable us to note that the shock wave increases the effect of chemotherapy administered.
miR-335 Acts as a Tumor Suppressor and Enhances Ionizing Radiation-Induced Tumor Regression by Targeting ROCK1
Authors: Cheng Yanfeng , Shen Peng
Published: March 2020

Recent development of integrative therapy against melanoma combines surgery, radiotherapy, targeted therapy, and immunotherapy; however, the clinical outcomes of advanced stage and recurrent melanoma are poor. As a skin cancer, melanoma is generally resistant to radiotherapy. Hence, there is an urgent need for evaluation of the mechanisms of radioresistance. The present study identified miR-335 as one of the differential expression of miRNAs in recurrent melanoma biopsies post-radiotherapy. The expression of miR-335 declined in melanoma tissues compared to the adjacent tissues. Moreover, miR-335 expression correlated with advanced stages of melanoma negatively. Consistent with the prediction of STARBASE and miRDB database, miR-335 targeted ROCK1 via binding with 3′-UTR of ROCK1 directly, resulting in attenuation of proliferation, migration, and radioresistance of melanoma cells. The authors validated that overexpression of miR-335 enhanced X-ray-induced tumor regression by B16 mouse models. Briefly, the present findings gained insights into miR-335/ROCK1-mediated radiosensitivity and provided a promising therapeutic strategy for improving radiotherapy against melanoma.

A main focus in microgrids is the power quality issue. The used renewable sources fluctuate and this fluctuation has to be suppressed by designing a control variable to nullify the circulating current caused by voltage fluctuations and deviations. The switching losses across power electronic switches, harmonics, and circulating current are the issues that we discuss in this article. The proposed intelligent controller is an interface between a voltage-sourced converter and a utility grid that affords default switching patterns with less switching loss, less current harmonic content, and overcurrent protection, and is capable of handling the nonlinearities and uncertainties in the grid system. The interfaced controller needs to be synchronized to a utility grid to ensure that the grid–lattice network can be fine-tuned in order to inject/absorb the prominent complex reactive energy to/from the utility grid so as to maintain the variable power factor at unity, which, in turn, will improve the system’s overall efficiency for all connected nonlinear loads. The intelligent controller for stabilizing a smart grid is developed by implementing a fuzzy-built advance control configuration to achieve a faster dynamic response and a more suitable direct current link performance. The innovation in this study is the design of fuzzy-based space vector pulse width modulation controller that exploits the hysteresis current control and current compensation in a grid-connected voltage source converter. By using the proposed scheme, a current compensation strategy is proposed along with an advanced modulation controller to utilize the DC link voltage of a voltage source converter. To demonstrate the effectiveness of the proposed control scheme, offline digital time-domain simulations were carried out in MATLAB/Simulink, and the simulated results were verified using the experimental setup to prove the effectiveness, authenticity, and accuracy of the proposed method.

Published: March 2020

Microcracks caused by perforating operations in a cement sheath body and interface have the potential to further expand or even cause crossflow during hydraulic fracturing. Currently, there are few quantitative studies on the propagation of initial cement-body microcracks. In this paper, a three-dimensional finite element model for the propagation of initial microcracks of the cement sheath body along the axial and circumferential directions during hydraulic fracturing was proposed based on the combination of coupling method of fluid–solid in porous media and the Cohesive Zone Method. The influence of reservoir geological conditions, the mechanical properties of a casing-cement sheath-formation system, and fracturing constructions in the propagation of initial axial microcracks of a cement sheath body was quantitatively analyzed. It can be concluded that the axial extension length of microcracks increased with the increase of elastic modulus of the cement sheath and formation, the flow rate of fracturing fluid, and casing internal pressure, and decreased with the increase of the cement sheath tensile strength and ground stress. The elastic modulus of the cement sheath had a greater influence on the expansion of axial cracks than the formation elastic modulus and casing internal pressure. The effect of fracturing fluid viscosity on the crack expansion was negligible. In order to effectively slow the expansion of the cement sheath body crack, the elastic modulus of the cement sheath can be appropriately reduced to enhance its toughness under the premise of ensuring sufficient strength of the cement sheath.
Modelling the Disaggregated Demand for Electricity in Residential Buildings Using Artificial Neural Networks (Deep Learning Approach)
Authors: Jasiński Tomasz
Published: March 2020

The paper addresses the issue of modelling the demand for electricity in residential buildings with the use of artificial neural networks (ANNs). Real data for six houses in Switzerland fitted with measurement meters was used in the research. Their original frequency of 1 Hz (one-second readings) was re-sampled to a frequency of 1/600 Hz, which corresponds to a period of ten minutes. Out-of-sample forecasts verified the ability of ANNs to disaggregate electricity usage for specific applications (electricity receivers). Four categories of electricity consumption were distinguished: (i) fridge, (ii) washing machine, (iii) personal computer, and (iv) freezer. Both standard ANNs with multilayer perceptron architecture and newer types of networks based on deep learning were used. The simulations included over 10,000 ANNs with different architecture (number of neurons and structure of their connections), type and number of input variables, formulas of activation functions, training algorithms, and other parameters. The research confirmed the possibility of using ANNs to model the disaggregation of electricity consumption based on low frequency data, and suggested ways to build highly optimised models.
