Lean Work and Gender Inequalities: Manufacturing Consent at a Multinational Car Plant in Provincial Russia
Authors: Krzywdzinski Martin , Lechowski Grzegorz , Mählmeyer Valentina
Published: June 2019

How do local labour market structures, in tandem with workforce dispositions and attitudes, influence the way multinational companies localise their standardised work and production systems? This article investigates the conflict-ridden factory regime of a lean automotive plant in provincial Russia at which the management was able to secure a relatively high level of consent among its female workers but not among male workers. In order to explain this gendered pattern of worker consent, the plant-internal gender division of labour and two societal factors proved crucial: the gendered segmentation of the local labour market and the workers’ cultural dispositions. At the same time, the analysis points to the transformative effect that the company’s work and production system had on the local labour regime. The case study relies on a combination of quantitative survey data and qualitative interviews. It emphasises the need to reconnect the analysis of branch-plant factory regimes to a nuanced understanding of their embeddedness within local labour markets – also in the case of highly standardised work and production systems.

Authors: Gaw Christopher E. , Spiller Henry A. , Casavant Marcel J. , Chounthirath Thitphalak , Smith Gary A.
Published: June 2019

OBJECTIVES:

To investigate exposures to liquid laundry detergent packets among children <6 years old in the United States and to evaluate the impact of the American Society for Testing and Materials voluntary product safety standard.

METHODS:

Data from the National Poison Data System involving exposures to liquid laundry detergent packets from 2012 to 2017 were analyzed.

RESULTS:

From January 2012 to December 2017, there were 72 947 single and polysubstance exposures to liquid laundry detergent packets. Most exposures (91.7%) were documented among children <6 years old. The annual number and rate of exposures for children <6 years old increased by 110.4% and 111.9%, respectively, from 2012 to 2015. From 2015 to 2017, the number and rate of exposures in this age group decreased by 18.0%. Among individuals ≥6 years old, the annual number and rate of exposures increased by 292.7% and 276.7%, respectively, from 2012 to 2017. Annual hospital admissions among children <6 years old increased by 63.4% from 2012 to 2015 and declined by 55.5% from 2015 to 2017. Serious outcomes among children <6 years old increased by 78.5% from 2012 to 2015 and declined by 32.9% from 2015 to 2017.

CONCLUSIONS:

The number, rate, and severity of liquid laundry detergent packet exposures have decreased modestly in recent years among children <6 years old, likely attributable, in part, to the voluntary product safety standard and public awareness efforts. Exposures among older children and adults are increasing. Opportunities exist to strengthen the current product safety standard to further reduce exposures.

AbstractThis study developed a conceptual framework on interactivity in the classroom, interactivity within Learning Management System (LMS), student engagement and satisfaction as four key underlying factors that will enhance learning outcomes. Furthermore, the study investigates interactivity in the classroom and within LMS with respect to student engagement, student satisfaction and its impact on educational learning outcome. Data were collected using a structured questionnaire. Based on the survey data from 178 respondents, SEM was employed to assess the model. We also experimentally assessed the relationship between the variables of the model by employing SEM method. However, the findings indicate that high interactivity in the classroom has a positive influence on student engagement and student satisfaction towards improving student learning outcomes. Also, the study shed more light on the moderate level of interactivity within the LMS by the student and pointed out which areas should be improved. The result further indicates the importance of interactivity in the educational environment and points to the need for more interactivity in the learning space of educational institutions.Key words: classroom; interactivity; learning outcomes; Learning Management System; university.---SažetakU ovom istraživanju izrađen je konceptualni okvir o interaktivnosti studenata u učionici, interaktivnosti studenata u sustavu za upravljanje učenjem, sudjelovanju studenata u nastavi i njihovu zadovoljstvu nastavom. To su bila četiri ključna čimbenika koja vode boljim ishodima učenja. Nadalje, istraživanjem se ispitala i interaktivnost u učionici i interaktivnost u sustavu za upravljanje učenjem s obzirom na sudjelovanje studenata u nastavi, njihovo zadovoljstvo nastavom i utjecaju koji sve navedeno ima na obrazovne ishode. Podaci su prikupljeni s pomoću strukturiranog upitnika i utemeljeni na obradi podataka dobivenih od 178 ispitanika. Za procjenu modela primijenjena je SEM metoda. Također smo eksperimentalno procijenili i vezu među varijablama unutar modela s pomoću SEM metode. Međutim, rezultati pokazuju da velika količina interaktivnosti u učionici ima pozitivan utjecaj na sudjelovanje studenata u nastavi i na njihovo zadovoljstvo, a da to sve vodi boljim ishodima učenja. Istraživanje je također razjasnilo i umjerenu interaktivnost među studentima u sustavu za upravljanje učenjem te istaknulo područja koja je potrebno doraditi. Taj rezultat pokazuje i važnost interaktivnosti u obrazovnom okruženju i ističe potrebu za većim stupnjem interaktivnosti u okruženju za učenje u obrazovnim institucijama. Ključne riječi: učionica, interaktivnost, ishodi učenja, sustav za upravljanje učenjem, sveučilište
A Critical Analysis of the PISA Mathematics Tasks/Kritički prikaz matematičkih zadataka PISA testa
Authors: Marković Olivera , Pikula Milenko , Zubac Marina
Published: June 2019

AbstractIn this paper, the authors deal with a critical analysis of some of the problems associated with PISA testing in mathematics. First of all, the social, economic and political circumstances of the launch of the PISA project are pointed out. This is followed by an analysis of what the authors consider as very important concepts for understanding PISA philosophy, such as applicable knowledge and problem solving in a real-life situation. We compared two different ways of defining these concepts and showed what the consequences of learning and teaching mathematics are in each of the cases. The authors present the results of the research that was conducted with mathematics teachers, as well as teachers of other subjects. The research dealt with the determination of the importance and role of the mathematical tasks of the PISA test for students’ further mathematical education. The results of the research have shown that there is a significant statistical difference between the assessment provided by the teachers who do and those who do not teach mathematics. The paper also analysed some specific tasks that the students were solving in PISA tests. The authors point out some deficiencies and inaccuracies observed in the mathematics tasks on PISA tests, as well as the weaknesses of PISA testing itself.Key words: functional knowledge; mathematical literacy; real-life situation; teaching mathematics. --- Sažetak U ovom radu autori se bave kritičkom analizom nekih problema vezanih uz PISA testiranje iz matematike. Prije svega ukazano je na društvene, ekonomske i političke okolnosti  pokretanja PISA projekta. Zatim su analizirani, po mišljenju autora, vrlo važni pojmovi za razumijevanje PISA filozofije, a to su primjenjivo znanje i rješavanje problema u stvarnoj životnoj situaciji. Usporedili smo dva različita načina definiranja ovih pojmova i pokazali koje su posljedice po učenje i nastavu matematike u oba slučaja. Izložili smo rezultate istraživanja koje smo proveli s nastavnicima matematike, ali i nastavnicima drugih predmeta. Istraživanje se odnosilo na utvrđivanje značaja i uloge matematičkih zadataka PISA testa za daljnje matematičko obrazovanje učenika. Rezultati istraživanja su pokazali da postoji statistički značajna razlika između procjena nastavnika koji predaju i nastavnika koji ne predaju matematiku. U radu smo analizirali i konkretne zadatke koje su učenici rješavali na PISA testiranju. Ukazali smo na izvjesne nedostatke i nepreciznosti matematičkih zadataka PISA testova, kao i na slabosti samog PISA testiranja.  Ključne riječi: funkcionalno znanje; matematička pismenost; nastava matematike; stvarna životna situacija.
Classroom Quality in Final Grades of Lower Secondary Education: Demographic Differences and Relationship with Target Learning Orientations / Kvaliteta nastave u završnim razredima nižeg sekundarnog obrazovanja: demografske razlike i povezanost s ciljnim
Authors: Đuranović Marina
Published: June 2019

AbstractThe goal of the research was to examine the features of classroom quality concerning gender, grade and general academic record, and the connection with target orientations in learning among students in the final grades of primary school (lower secondary education, ISED level 2). Seventh- and eighth-grade students (N=512) from Split-Dalmatia County and the City of Zagreb participated in the research. The questionnaire was used to collect demographic data (gender, grade and final academic record). For data regarding self-assessment of classroom quality, we used the Student Perception of Classroom Quality Questionnaire – SPOCQ. Data about target orientations was collected through the Components of Self-Regulated Learning Questionnaire – CRSL. The given results show that students, regardless of age, gender or general academic record, mostly perceive classes as average on all quality dimensions and are inclined to all three learning orientations somewhat above average. Furthermore, aspects of classroom quality were shown as the most significant predictors of all individual target orientations in learning, considering the fact that almost one third of the learning orientation is explained with classroom quality, but very little is directed to performance or avoiding effort. Key words: classroom quality; primary school; students; target orientations. ---SažetakCilj istraživanja bio je ispitati obilježja kvalitete nastave s obzirom na spol, razred i opći školski uspjeh te povezanost s ciljnim orijentacijama u učenju kod učenika završnih razreda osnovne škole (niže sekundarno obrazovanje, ISCED razina 2). U istraživanju su sudjelovali učenici sedmih i osmih razreda (N = 512) osnovnih škola Splitsko-dalmatinske županije i Grada Zagreba. Upitnikom su prikupljeni demografski podatci (spol, razred i završni uspjeh), a za podatke o samoprocjeni kvalitete nastave koristio se Upitnik učeničke percepcije kvalitete nastave (engl. Student perception of classroom quality - SPOCQ). Podaci o ciljnim orijentacijama u učenju prikupljeni su Upitnikom ciljnih orijentacija (Components of Self-regulated Learning – CSRL). Dobiveni rezultati ukazuju na to da učenici, bez obzira na dob, spol i opći uspjeh, uglavnom percipiraju nastavu prosječnom prema svim dimenzija kvalitete te da su blago iznadprosječno skloni svim trima orijentacijama učenja. Nadalje, kao najznačajniji prediktori sve pojedine ciljne orijentacije u učenju pokazali su se aspekti kvalitete nastave, s time da se kvalitetom nastave objašnjava gotovo trećina orijentacije na učenje, ali veoma malo orijentacije usmjerene na izvedbu i izbjegavanje truda.     Ključne riječi: ciljne orijentacije; kvaliteta nastave; osnovna škola; učenici

Published: June 2019

Abstract This research has been conducted with the aim of evaluating gender and age differences in attitudes of Serbian students toward Physical Education lessons and their preferences regarding lesson organisation. The sample of 542 students was divided into 4 subsamples: 140 female primary school pupils (13.51±0.41) and 129 male primary school pupils (13.47±0.33) from grade seven, and 134 secondary school female pupils (16.49±0.36) and 139 secondary school male pupils (16.44±0.37) from grade two. For the purpose of the research, the subjects voluntarily filled in two standardised questionnaires. ANOVA was used to determine significant differences in attitudes toward Physical Education lessons between pupils of different age and of different gender, while a Chi-square test was used to determine significant differences in pupils’ preferences regarding Physical Education lesson organisation. The results showed that primary school pupils had significantly more positive attitudes toward Physical Education lessons in relation to secondary school pupils, and that younger pupils prefer gender-based organisation of lessons which changes with respect to age and gender. Key words: lessons; primary and secondary schools; Serbia.---Sažetak Ovo istraživanje provedeno je s ciljem ispitivanja spolnih i dobnih razlika u stavovima srbijanskih učenika prema nastavi Tjelesne kulture i njihovim preferencijama prema načinu organizacije nastave.

Published: June 2019

Simulation results of an irradiation and PV array performance software package (SunSim) are pre-sented. South African irradiation data availability is discussed, an irradiation data classification system proposed, and the estimation of diffuse irradiation on tilted surfaces analysed. Estimation of PV array energy output using King’s performance model is explained, and the influence of the irradiation and temperature data set measurement interval on PV energy output estimation investigated. Simulation results are presented, aimed at identifying optimal fixed PV panel tilt angles and solar-tracking config-urations for different locations in South Africa. Lastly, the cost of PV-based generation in South Africa is investigated.
The impact of electricity crises on the consumption behaviour of small and medium enterprises
Authors: Von Ketelholdt A. , Wöcke A.
Published: June 2019

Small and medium enterprises (SMEs) will play a key role in future economic and social strategies in South Africa. However, we find that SMEs are par-ticularly vulnerable to shocks in their external envi-ronment due to a general lack of skills and resources. This is critical as the future demand for electricity in South Africa is likely to outstrip supply and electricity will become increasingly unreliable and expensive. We surveyed 250 SMEs in Cape Town and found that the prevailing policy methods of changing electricity consumption behaviour: information campaigns, increasing prices, and pro-viding rebates for energy savings, have had limited results and are unsustainable when applied to SMEs.
Development of a biofuel lamp and its comparison with a kerosene lamp
Authors: Chakraborty N. , Sarkar S.C.
Published: June 2019

An attempt has been made to explore the suitability of crude Jatropha curcas seed oil (biofuel) as a fuel in substituting fully one of the important petroleum products like Kerosene. Expeller is used for the extraction of oil which is further filtered. This crude oil has a very high viscosity and, as result, cannot flow through capillary action in a standard lamp and, hence, requires viscosity reduction by a trans esterification process to convert it into biodiesel or by any other processes. But this is a complex chem-ical reaction and the cost of production becomes almost doubled unless glycerine is not recovered as a by-product. Hence, the paper describes the devel-opment of a unique lamp (lantern) fuelled by 100%biofuel (crude jatropha oil) for its illumination and its comparative performance with respect to a stan-dard kerosene lamp.

Published: June 2019

Many individuals with advanced glaucoma and retinal dystrophies have functional difficulty due to a loss of peripheral vision. These individuals may have sufficient central vision to read and perform visual tasks in a controlled situation, but are often unable to function in a cluttered, unstructured or chaotic environment (i.e. a normal social situation). This is because they lack the ability to be visually alerted to an incentive or threat outside the narrowed region of their central vision. Some groups of these patients, for example those with a diagnosis of retinitis pigmentosa, also experience nyctalopia (night blindness) meaning that time of day can alter their functional ability. Currently, there are limited options to aid these patients. Intel Corporation has developed a computer-based assistive device that may be useful for these individuals. Intel has recently made the design details and software available via the internet. The device consists of a vest or shirt with an attached depth-sensing camera, a computer and vibration transducers (6 on the vest and one on each foot). The transducers vibrate to alert the wearer to objects that are approaching them, or if they are walking, alert them to objects that they may be approaching. We propose to test subjects wearing the device to determine its usefulness. This will consist of participants with no known visual problems wearing goggles that will reduce their peripheral vision, replicating the effects of the diseases mentioned. The participants will be asked to walk through simple maze scenarios wearing the vibration vest and two different pairs of goggles. Two versions will be performed with the vest switched off and then it will be activated, equalling four mazes per participant. Each participant will also answer two short questionnaires, one before and one after using the device, to help determine the possible benefits and drawbacks of the device. The results will then be analysed to conclude whether an electronic device such as this could be useful to enhance visual function in those with reduced peripheral vision. This could then be applied to patients affected by these diseases.

Granule Flavor EnhancerAbstractThis research aims to determine the effect of deep-fat frying on the content of glutamic acid in Spirulina sp. granule flavor enhancer that has been applied to the flour dough. Preliminary research was produced three formulas of Spirulina sp. granule flavor enhancer, that were formulated based on sugar and salt content on three commercial seasoning brands. Thus, three formulas were applied to wheat flour then fried with deep-fat frying method at 140, 160, and 180oC until cooked well. The color of doughs before and after frying were analyzed using chromameter. The glutamic acid content were analyzed using L-glutamate assay kit and tested by spectrophotometer at 492 nm. As results, frying process changed the color of the dough. The increase in the frying temperature from 140 to 180oC caused a decrease in value of L from ± 47 to ±39, value of b* from ± 26 to ±19, and increase the value of a* from ±8 to ±10. The increase in the temperature of frying from 140 to 180oC caused a decrease in glutamic acid content of Spirulina sp. from ±8 to ±3 mg/100 g. As conclusion, increase in the frying temperature might cause a change in color and decreased content of glutamic acid in the doughs.
The Legal Role of Establishing the Origin of the Child in Legal Relations based on Inheritance when Assisted Reproductive Technologies are Applied
Authors: Aminova F. M.
Published: June 2019

The author argues that it is necessary to amend the current legislation of the Republic of Tajikistan, namely, the procedure provided for registration of data regarding parents and child birth registration when the child is born as a result of application of assisted reproductive technologies after the death of the parent in order to make the child the participant of the relations based on inheritance. The author substantiates the conclusion that the child born after the death of the testator, after the distribution of hereditary property had taken place, will not be able to act as the participant of this hereditary relationship. However, being recognized as a legitimate child of the deceased parent, he or she will be entitled to participate in inheritance relations in future.

The conclusion is made about ambiguity of the approach chosen by the Tajik law-maker depending on the branch of law to the category «child in the womb» when determining problematic aspects of defining of live birth and vitality of the child for the purpose of referring the child to the participants of hereditary legal relations.

The author investigates the problems of including the child into the number of participants of hereditary legal relations in antiquity. A historical review is carried out, and separate categories of marriages created in the territory of historical Tajikistan for the purpose of the child birth in order to transfer inheritance are considered. The author has determined that Zoroastrian law allowed the child born from the deceased person prior to the conception of the child to participate in hereditary legal relations as if the child were native and would be born during the life of a «legal» father. There were no legal obstacles for a child born in this case preventing him or her from receiving inheritance The beginnings of «traditional» surrogacy motherhood in the territory of historical Tajikistan are determined.

A Mixed-Methods, Community-Based Study To Identify Predictors Of Depression In Latino Adolescents By Gender
Authors: Bigatti Silvia M. , Diaz Virna , Conrad Katrina K. , Ramirez Michelle , Weathers Tess D.
Published: June 2019

Latino adolescent depressive symptoms are a growing problem, of interest to both the community and academic partner who are reporting the present study. In this mixed-method, community-based participatory research study we quantitatively examined predictors of depression known to impact adolescent mental health that are amenable to interventions. Concurrently, we qualitatively assessed parents’ perceptions of mental health problems in children, their causes and potential solutions. The data from parents (n = 108) was obtained in focus groups led in Spanish, and the data from adolescents (n = 86) was obtained in English language surveys. Among the adolescents there was an even representation of males (47.7%) and females (52.3%), Mage = 15.24 (SD = 1.97). Nearly half (47.7%) of the adolescents were experiencing minor depression and one in ten (10.5%) were experiencing major depression according to their scores on the PHQ-9. Adolescent participants reported low acculturative stress, average social support, and high mastery, as well as highly functional families. Males reported higher self-mastery than females and lower acculturative stress. Predictors of depression differed by gender. For males, self-mastery predicted depressive symptoms; for females acculturative stress predicted depressive symptoms. The focus groups with parents supported and expanded quantitative findings. The parents demonstrated a keen awareness of depression in teens and their own contributions to the problem, including their efforts to maintain their culture of origin which prevents integration of their children into the majority culture.  Parents also reported difficulties knowing what steps to take and finding resources. The additional dimension of parental voice is often missing from studies of adolescents, and here it clarified many of the issues identified in the teens. These findings suggest the need to focus on mental health in this population, potentially developing differential interventions by gender and taking a family systems approach.
The duality of a pastry chef's creative process
Authors: Lee Kai-Sean , Blum Denise , Miao Li , Tomas Stacy R
Published: June 2019

This study focuses on elite Malaysian pastry chefs who have participated in the World Pastry Cup. It poses the question, “How do World Pastry Cup chefs experience the creative process?” Specifically, this study explored the rhetoric (identity formation) of pastry chefs during the creative process. Findings show that pastry chefs bounce between two distinct rhetorics during the creative process, ‘the scientist’ and ‘the artist.’ This identity interchange is presented as a ‘duality,’ as one’s way of being revolves around detailed experimentations and rationalism (the scientist), whilst the other around poetry and artistic intent (the artist).

Purpose of Study:  One important aspect in regional development planning is to grow regional economies. It is expected to be a leverage and and attract other sectors to move and grow well. To develop the local economy, there are several things to be used as basis for regional development. The present aims to analyze the regional economic potentials in the development of superior markets of a nation.

Methodology: Exploratory research method is used in the present study to obtain more in-depth results that can be developed according to the outcomes of the analysis. It has been carried out by determining the selection of one of the district's superior products. By using the endogenous development strategy paradigm and integrating endowment factors with human resources capabilities, the development and growth of Bondowoso Regency will be more directed, clear, measurable and targeted. In an effort to realize the development of new economic growth centers in undeveloped areas, determining superior products is very important. Furthermore, by encouraging the development of the specific potential of underdeveloped regions, it is expected to be able to encourage and accelerate economic growth and improve community welfare. so that this builds a new center for economic growth. In general, the flagship program of each district is used as leverage in stimulating regions for development. Notably, there are six parameters left behind. These include the community economy, human resources, infrastructure (infrastructure), local financial capacity (fiscal gap), accessibility, and regional characteristics. It is expected that poverty alleviation and unemployment reduction can be achieved through an increase in the local financial capacity through optimization of the potential of local products. The development of district superior product programs in growth node will be beneficial in encouraging the economic growth of the community.

Nadciśnienie tętnicze należy do najbardziej rozpowszechnionych chorób. Cierpi na nie około miliarda ludzi na świecie,
z czego u 1–2% na pewnym etapie choroby rozwinie się przełom nadciśnieniowy. Przełom nadciśnieniowy (kryza nadciśnienowa)
to sytuacja, w której wartość ciśnienia skurczowego (systolic blood pressure – SBP) wynosi co najmniej
180 mmHg i/lub rozkurczowego (diastolic blood pressure – DBP) 120 mmHg. Wyróżnia się dwie podstawowe kategorie
kliniczne: stany pilne oraz stany naglące, którym towarzyszy postępujące uszkodzenie narządów wewnętrznych.
W artykule omówiono aktualne zalecenia dotyczące najczęściej występujących stanów sercowo-naczyniowych w przebiegu
kryzy nadciśnieniowej, tj. kardiogennego obrzęku płuc, udaru niedokrwiennego mózgu, ostrego zespołu wieńcowego,
encefalopatii nadciśnieniowej, rozwarstwienia aorty oraz zatrucia substancjami psychoaktywnymi. Głównym
celem w leczeniu ostrych stanów sercowo-naczyniowych w przebiegu kryzy nadciśnieniowej jest redukcja ciśnienia
tętniczego w ciągu minut do godzin lekami stosowanymi dożylnie. Zdecydowanie bardziej agresywne obniżenie ciśnienia
tętniczego jest akceptowane w przypadku ostrego rozwarstwienia aorty. Zbyt szybka redukcja ciśnienia może jednak
prowadzić do uszkodzenia ważnych życiowo narządów, dlatego niezwykle ważne jest prowadzenie leczenia hipotensyjnego
w kontrolowany sposób.

A study was conducted to evaluate the effect of different fertilizers in GIFT Tilapia culture using biofloc technology. Animals (5±0.23g) were stocked at a density of 30m-3 in 500 litres FRP tanks and spentwash was used as a carbon source to maintain a C:N ratio of 10:1 for 42 days. The experimental group includes fertilization using ammonia sulphate alone (T1) and fertilization using different inorganic fertilizers (T2). No significant differences in FCR, specific growth rate, weight gain and survival of animals were found between the treatments. Proximate composition and fatty acid profile of floc were comparatively rich in T2. Increased solid concentrations with higher Floc volume index and floc sizes were recorded in T2. The rapid floc development along with multiplication of heterotrophic bacteria and decreased vibrio population was observed in T2. The present study confirmed the influence of fertilizers on the physical and nutritional quality of biofloc in GIFT tilapia culture.
Properties, Characteristics and Parameters of Permanent Magnet Synchronous Motors under Vector and Scalar Frequency Control
Authors: Firago B. I. , Aleksandrovsky S. V.
Published: June 2019

In order to improve energy performance and simplify the system of frequency control of the speed of electric drives, the area of application of synchronous frequency-controlled electric drives with both dependent and independent frequency setting of the voltage supplying the engine is being expanded. This is due to the fact that, as compared with asynchronous variable frequency drives, synchronous ones undergo lower power losses and they have rigid mechanical characteristics without speed feedback. Also, the simplest law of frequency control, viz. a proportional one, which, however, provides the maximum electromagnetic torque of the engine unchanged at R1 = 0 at all frequencies due to the constant magnetic flux, is applicable to a synchronous frequency controlled motor. Characteristics and properties of permanent magnet synchronous motors (PMSM) with the dependent frequency setting of supplied voltage (under vector control of PMSM) have been discussed and reviewed in technical literature quite sufficiently. It cannot be said about the PMSM with independent frequency setting reference which work under scalar frequency control. In the present article a comparison of properties and characteristics of vector and scalar frequency controlled PMSM is presented. For a scalar frequency controlled PMSM a function of the relative voltage g on the relative frequency a (g = f(a)) taking into account the PMSM parameters has been defined. The derived function g = f(a) differs from a proportional law of frequency control g = a. It is found that the influence of the parameters on the law of frequency control is small, and it can be applied without adjustment in most cases, in contrast to the frequency control of the asynchronous motor. For scalar frequency control, a method for determining the parameters of synchronous motors has been proposed in accordance with the parameters of synchronous motors with permanent magnets, which are given for operation under vector control. According to the presented methodology the OMRON SGMH-50D engine parameters have been determined for scalar frequency control and the function of g = f(a) have been computed.

To assess the effects of the combination of DAPT and oxaliplatin on the biological behavior of human ovarian cancer stem cells. In vitro cultured human ovarian cancer stem cells were randomly divided into DAPT, L-OHP, DAPT + L-OHP, and control groups. MTT assays were measured to assess the ability of inhibit proliferation. Inverted microscopy, flow cytometry, and in vitro invasion assays were performed to assess cell morphology, apoptosis, and cell invasion, respectively. Then, western blotting was used to detect Notch-1 and LRP1 expression in the four groups of cells. MTT assay revealed that DAPT and L-OHP monotherapy could inhibit the proliferation of ovarian cancer stem cells in a time- and dose-dependent manner. Inverted microscopy showed that untreated ovarian cancer stem cells had an oval or polygonal morphology, with a plump shape and large nuclei. After treatment with DAPT or L-OHP, cells shrank and cracked, with an irregular shape and increased shedding. Flow cytometry revealed that apoptosis was significantly higher in the DAPT and L-OHP groups compared with the control group; the DAPT + L-OHP group had a significantly higher rate of apoptosis than either the DAPT or L-OHP groups. An in vitro invasion assay revealed that DAPT + L-OHP inhibited cell invasion to a greater extent than either DAPT or L-OHP alone. Western blotting revealed that, compared with control, L-OHP had no effect on Notch-1 protein expression, whereas DAPT and DAPT + L-OHP significantly reduced Notch1 protein levels. In addition, cells treated with DAPT + L-OHP expressed much less Notch than those treated with DAPT alone. In the L-OHP group, LRP protein levels were increased significantly, whereas levels were decreased significantly in the DAPT and DAPT + L-OHP groups. DAPT inhibits the proliferation of ovarian cancer stem cells, promotes their apoptosis, weakens their invasive ability, and functions synergistically with L-OHP.

Background: The occurrence of a mediastinal germ cell tumor (GCT) and hematological malignancy in the same patient is very rare. Due to its rarity, there have been only two reports of the concurrent cases undergoing detailed genetic analysis with whole-exome sequencing (WES), and the possible clonal relationship between the both tumors remained not fully elucidated.
Methods: We performed whole-exome sequencing analysis of mediastinal GCT and acute myeloid leukemia (AML) samples obtained from one young male adult patient with concurrent both tumors, and investigated the possible clonal relationship between them.
Results: 16 somatic mutations were detected in the mediastinal GCT sample and 18 somatic mutations in the AML sample. Mutations in nine genes, including TP53 and PTEN both known as tumor suppressor genes, were shared in both tumors.
Conclusions: All in our case and in the previous two cases with concurrent mediastinal GCT and AML undergoing with whole-exome sequencing analysis, TP53 and PTEN mutations were commonly shared in both tumors. These data not only suggest that these tumors share a common founding clone, but also indicate that associated mediastinal GCT and AML harboring TP53 and PTEN mutations represent a unique biological entity.

Background

Breast cancer (BRCA) is one of the most common malignancies in women. To reveal the molecular mechanism of the BRCA, the core genes associated with BRCA was studied by the integrated bioinformatics methods in the current study.

Results

A total of 1181 DEGs, 84 DEGs, and 190 DEGs were detected in GSE7904, GSE10797, and GSE103512, respectively. In addition, 7 hub genes overlapped from 3 datasets were selected, and ANNXA1, MYH11, IGFBP6, FOS, FOSB, KIT, and WLS might be the core genes of BRCA. The Go function analysis showed that the DEGs were enriched in chromosome segregation, gland development, leukocyte migration, extracellular structure organization and so on. The KEGG pathway analysis showed that the most DEGs were enriched in Pathways in cancer, Focal adhesion, ECM-receptor interaction, PPAR signaling pathway, etc. Additionally, ANXA1 was associated with worse overall survival, and the other 6 hub genes were associated with better overall survival.

Conclusions

ANNXA1, MYH11, IGFBP6, FOS, FOSB, KIT, and WLS might be the core genes of BRCA. WLS, IGFBP6, and FOSB might be a new biomarker of the breast tumor and potential new drug targets. This study provided new evidence for the future genomic individualized treatment of BRCA.
Efficacy of intranasal dexmedetomidine for removal of inhaled foreign bodies in children by flexible fiberoptic bronchoscopy: a randomized, double-blind, placebo-controlled clinical trial
Authors: Bi Yanmei , Ma Yushan , Ni Juan , Wu Lan
Published: June 2019

Background: The traditional technique for foreign body removal is rigid bronchoscopy. However, fiberoptic bronchoscopy is becoming more popular for foreign body removal. Compared with rigid bronchoscopy, fiberoptic bronchoscopy is better suited for removing foreign bodies from the distal airways and upper lobe bronchi because of the smaller diameter and greater flexibility of the bronchoscope. Dexmedetomidine, a highly selective α2 adrenergic agonist, reduces preoperative anxiety, reduces the requirement for general anesthetics, and does not induce respiratory depression. The safety and efficacy of intravenous dexmedetomidine have been confirmed in patients undergoing fiberoptic bronchoscopy. Intranasal dexmedetomidine reportedly produce satisfactory sedation in children. We hypothesized that intranasal dexmedetomidine at 1 µg·kg−1 administered 25 minutes before anesthetic induction can reduce the incidence of adverse events during fiberoptic bronchoscopy under sevoflurane inhalation general anesthesia.
Methods: Forty preschool-aged children (6–48 months) with an American Society of Anesthesiologists physical status of I or II were randomly allocated to receive either intranasal dexmedetomidine at 1 µg·kg−1 or normal saline at 0.01 ml·kg−1 25 minutes before anesthetic induction. The primary outcome was the incidence of perioperative adverse events. The heart rate, respiratory rate, separation score, tolerance of the anesthetic mask, agitation score, anesthetic induction time, consumption of sevoflurane, and recovery time were also recorded.
Results: The incidence of laryngospasm, breath-holding, and coughing were significantly lower in patients who received intranasal dexmedetomidine than saline (15% vs. 50%, P=0.018; 10% vs. 40%, P=0.028; and 5% vs. 30%, P=0.037, respectively). Patients who received intranasal dexmedetomidine had a lower separation score (P=0.017), more satisfactory tolerance of the anesthetic mask (P=0.027), a significantly shorter anesthetic induction time (5.75±1.4 vs. 7.75±2.5 min, P=0.004), and less consumption of sevoflurane (38.18±14.95 vs. 48.03±14.45 ml, P=0.041). The recovery time was similar in both groups, and the frequency of postoperative agitation was significantly lower in patients who received intranasal dexmedetomidine (P=0.004).
Conclusions: Intranasal dexmedetomidine at 1 µg·kg−1 can reduce the incidence of laryngospasm, breath-holding, and coughing during fiberoptic bronchoscopy for foreign body removal via its sedative and analgesic effects. Moreover, intranasal dexmedetomidine can reduce postoperative agitation without a prolonged recovery time.
