Published: January 2021

A honlapok jelentik általában a vállalkozások online jelenlétének alapját. A szerzők célja olyan átfogó értékelési rendszer létrehozása volt, amely képzettség nélkül is alkalmazható, ezzel segítve a vállalkozások saját weboldalainak fejlesztését. Az online elérhető tesztelő oldalak, illetve versenyek csupán korlátozottan alkalmazhatók a kisebb vállalkozások esetében. Ezért a szekunder források áttanulmányozása után 12 szakértői interjú lefolytatására került sor vezető beosztású szakemberekkel, amelyek alapján azonosításra kerültek a weboldalak értékelésének témakörei és tényezői, ezzel lehetővé téve egy 100 pontos rendszer kialakítását. Ez a megoldás olyan újszerű lehetőség a digitálisan kevésbé érett, korlátozott anyagi és szakmai háttérrel rendelkező vállalkozások számára, amely objektív visszajelzést ad a weboldalukról, emellett rávilágít a hiányosságokra, a szükséges fejlesztési irányokra. A rendszer ezzel edukálhatja a KKV-kat, illetve alkalmas a versenytársakkal való összehasonlításra is.

Authors: Fazullina Olga N. , Korbut Anton I. , Dashkin Maksim V. , Klimontov Vadim V.
Published: January 2021

BACKGROUND: Type 2 diabetes and osteoporosis are widespread diseases in the middle-aged and elderly people. Most studies of osteoporosis in patients with type 2 diabetes have been performed in women; meantime risk factors for lowering bone mineral density (BMD) in men have been little studied.

AIMS: to identify risk factors for decreased BMD at the lumbar spine, femoral neck and forearm in men with type 2 diabetes.

METHODS: Eighty two men from 50 to 75 years old, with duration of diabetes for at least one year, were included in the study. Individuals with known risk factors for secondary osteoporosis were not included. Twenty-three men with normal BMD having no diabetes or obesity were acted as control. The T-score at the lumbar spine, femoral neck and forearm of a non-dominant arm, as well as body composition parameters, were evaluated by dual-energy X-ray absorptiometry. The levels of hormones that affect bone metabolism (parathyroid hormone, free testosterone, 25-OH vitamin D) were measured in blood serum by ELISA. Risk factors for reducing BMD were identified using multivariate regression analysis and receiver operating characteristic (ROC) curves.

RESULTS: Among patients with diabetes, 49 individuals had normal BMD and 33 showed decreased T-score values (<-1 SD). Free testosterone <5.92 pg/ml was predictor for decreased BMD at the lumbar spine (OR=4.4, p=0.04). For femoral neck, the risk factors were body weight <95.5 kg (OR=2.8, p=0.04), total fat mass <27 kg (OR=3.3, p=0.03), truncal fat mass<17.5 kg(OR=4.5, p=0.006), android (central abdominal) fat mass <3.2 kg(OR=4.0, p=0.01), gynoid (hip) fat mass <3.5 kg(OR=3.3, p=0.02), and lean mass <59 kg(OR=3.0, p=0.04). Risk factors for reduced BMD at the forearm were diabetes duration>15.5 years (OR=3.7, p=0.03) and HbA1c <8.15% (OR=3.8, p=0.03). Parathyroid hormone and 25-OH-vitamin D did not predict BMD independently.

CONCLUSIONS: In men with type 2 diabetes, low free testosterone is a risk factor for decreased BMD in the lumbar spine, and diabetes duration is a risk factor for decreased BMD in the forearm. The presence of obesity is associated with an increase in BMD in the femoral neck; a high HbA1c is associated with an increase in BMD in the forearm.

BACKGRAUND: The need to create a national questionnaire for screening the population for disorders of carbohydrate metabolism.

AIMS: Develop a highly specific and sensitive questionnaire-calculator of the risk of prediabetes (PreD) and diabetes mellitus type 2 (DM2T) based on depersonalized data of individuals who have these diagnoses confirmed in the national epidemiological study NATION.

METHODS: The express method of prediabetes (PreD) and diabetes mellitus type 2 (DM2T) risks has been created, validated and proposed for clinical usage for the first time in the Russian Federation, it was based of NATION epidemiologic study database (more than 26 000 participants). The following mathematical instruments have been used: mathematic modelling, main components methodology, binary variables, correlation analysis and single-factor analysis of variance.

RESULTS: Highest coefficients of logistic regression for PreD (p<0.05) were identified for age — ≥52 years old for women and ≥59 years old for men (1,48); body mass index ≥31 (0.75); waist circumference ≥100 сm for women and ≥112 cm for men (0.90). In the same time coefficients for DM2T were for for age — ≥52 years old for women and ≥59 years old for men (1,24); body mass index ≥31 (1,19), high blood fasting glucose analysis in the past (1,37); waist circumference / hip circumference ratio ≥0.85 for women and ≥0.92 for men (1,05), high blood pressure (0.69). Correlation coefficients were taken into account and score has been used for specialized questionnaire creation. Sensitivity and specificity for PreD were 83,8% and 59,3% accordingly, for DM2T — 85,4% and 73,6% accordingly. DM2T may be suspected when total score of questionnaire is 11 and higher, and PreD — when total score will be ≥7 and <11.

CONCLUSIONS: The calculator based on questionnaire (DIARISK) allows to separate of potential patient for PreD and DM2T confirmation during first examination or dispanserization. A patent for innovation has been issued.

The application of hibah as an instrument in estate management is gaining popularity among the Muslim community in Malaysia. “Hibah is a unilateral contract” that elevate welfare and charity. The Islamic financial institutions in Malaysia, including Islamic banks as well as Islamic wealth institutions apply varities of hibah instruments in the products accessible by them. Hibah is a cooperating shariah contract in the Malaysia‟s Islamic banking and financial framework. The aim is to incentivize clients for storing their cash into the institution as well as remunerate for clients to pay their financing by agreeing planned. The use of hibah is based on the stated fundamentals and objectives of the “Shariah Advisory Council (SAC) of Bank Negara Malaysia”. Nowadays, hibah instrument has been applied in various forms using Islamic financial institutions especially in Malaysia. This article discusses and analyzes in general the application of contemporary forms of hibah such as Trust Hibah (Hibah Amanah), Conditional Hibah (Hibah Mu'allaqah), Hibah with discussion (Hibah Bi al-Thawab), hibah in saving account (Wadiah) and rental (al-Ijarah) accounts and hibah in Takaful benefit.

The article explores the peculiarities of the functioning and linguistic actualization of the proper names represented in the system of Lesia Ukrainka’s epistolary ethnic autostereotypes. The study has revealed the determinative role of the horonym Volyn and its derivatives волинський , волинська, волинське (volynskyi, volynska, volynske) in the formation of the system and regular use of Volyn astionyms Lutsk, Kovel, comonym Kolodyazhne and katoikonyms volyniaky / volyniaki, volynianochka / volynianka. The article focuses on the comparative analysis of the usage contexts of the nuclear oykonymic names of Volyn and the horonyms of other geographical territories of Ukraine and foreign states, in particular, Germany, Bulgaria and Georgia. The authors argue for the importance of using these names as elements of personal self-identification and a means of linguistic self-portraiture.
IRAK inhibitor can improve insulin sensitivity in insulin-resistant mice fed with a high-fat diet
Authors: Allahyari Mostafa , Rajaie Athena , Fallah Hossein
Published: January 2021

Background

Obesity and the inflammation associated with it, play a key role in the development of insulin resistance through the release of inflammatory cytokines and free fatty acids and the stimulation of toll-like receptors (TLR). Interleukin-1 receptor-associated kinase (IRAK), which mediates the activation of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway, is an important molecule in TLR signaling. The NF-κB pathway can reduce insulin efficacy by increasing the expression of proinflammatory cytokines. There is no safe inhibitor for the NF-κB pathway, and for this reason, the upper mediator of this pathway was selected for investigation.

Objectives

To determine the effects of an IRAK inhibitor on insulin resistance and serum biochemical factors in high-fat-fed insulin-resistant mice.

Methods

Insulin resistance was developed in C57BL/6J mice by 12 weeks of a high-fat diet. Subsequently, the IRAK 1/4 inhibitor 1-(2-(4-morpholinyl)ethyl)-2-(3-nitrobenzoylamino)benzimidazole (IRAKi)/or pioglitazone, or both, were administered for a further 2 weeks. After 12 h fasting, blood and tissue samples were collected, insulin and glucose levels were assayed, and the homeostatic model assessment was used to quantify insulin resistance (HOMA-IR).

Results

The IRAKi decreased blood glucose levels significantly (253 ± 14.3 mg/dL vs 390.1 ± 16.6 mg/dL) and increased insulin sensitivity compared with untreated controls. However, we did not find a synergistic effect of IRAKi with pioglitazone in increasing insulin sensitivity.

Conclusion

IRAKis can increase insulin sensitivity and their efficacy is comparable to pioglitazone. However, combined administration of pioglitazone and IRAKi had no synergistic effect compared with monotherapy.
TK-PUL, a pullulan hydrolase type III from Thermococcus kodakarensis, a potential candidate for simultaneous liquefaction and saccharification of starch
Authors: Toor Khurram Jahangir , Ahmad Nasir , Muhammad Majida Atta , Rashid Naeem
Published: January 2021

TK-PUL, a novel thermo-acidophilic pullulanase from Thermococcus kodakarensis and a unique member of glycoside hydrolase family GH13 was successfully produced in Escherichia coli grown by fed batch culture in a fermenter and partially purified by simple heat treatment. Specific activity of partially purified TK-PUL was 28 U/mg. Corn starch was successfully liquefied and saccharified using this single enzyme at pH 4.2. Simultaneous liquefaction and saccharification of corn starch by TK-PUL was comparable to Termamyl, a commercially available starch-hydrolyzing industrial enzyme. Both enzymes efficiently hydrolysed corn starch into sugar syrups having major proportions of maltose. TK-PUL performs efficiently at the natural pH of starch (~4.5) in the absence of any metal ions, hence is a potential candidate for starch industry.
Study on the characteristics of secondary arc current of UHV high compensation degree TCSC line under the fine-tuning mode
Authors: He Baina , Xie Yadi , Zhang Jingru , Nair Nirmal-Kumar C. , He Xingmin , Dong Yanchen
Published: January 2021

In the transmission line, the series compensation device is often used to improve the transmission capacity. However, when the fixed series capacitor (FSC) is used in high compensation series compensation device, the stability margin cannot meet the requirements. Therefore, thyristor controlled series compensator (TCSC) is often installed in transmission lines to improve the transmission capacity of the line and the stability of the system. For cost considerations, the hybrid compensation mode of FSC and TCSC is often adopted. However, when a single-phase grounding fault occurs in a transmission line with increased series compensation degree, the unreasonable distribution of FSC and TCSC will lead to the excessive amplitude of secondary arc current, which is not conducive to rapid arc extinguishing. To solve this problem, this paper is based on 1000 kV Changzhi-Nanyang-Jingmen UHV series compensation transmission system, using PSCAD simulation program to established UHV series compensation simulation model, The variation law of secondary arc current and recovery voltage during operation in fine tuning mode after adding TCSC to UHV transmission line is analyzed, and the effect of increasing series compensation degree on secondary arc current and recovery voltage characteristics is studied. And analyze the secondary arc current and recovery voltage when using different FSC and TCSC series compensation degree schemes, and get the most reasonable series compensation configuration scheme. The results show that TCSC compensation is more beneficial to arc extinguishing under the same series compensation. Compared with several series compensation schemes, it is found that with the increase of the proportion of TCSC, the amplitude of secondary arc current and recovery voltage vary greatly. Considering various factors, the scheme that is more conducive to accelerating arc extinguishing is chosen.
GPS measurements on pre-, co- and post-seismic surface deformation at first multi-parametric geophysical observatory, Ghuttu in Garhwal Himalaya, India
Authors: Gautam P.K. , Rajesh S. , Kumar N. , Dabral C.P.
Published: January 2021

We investigate the surface deformation pattern of GPS station at MPGO Ghuttu (GHUT) to find out the cause of anomalous behavior in the continuous GPS time series. Seven years (2007-2013) of GPS data has been analyzed using GAMIT/GLOBK software and generated the daily position time series. The horizontal translational motion at GHUT is 43.7 ± 1 mm/yr at an angle of 41°± 3° towards NE, while for the IGS station at LHAZ, the motion is 49.4 ±1 mm/yr at 18 ± 2.5° towards NEE. The estimated velocity at GHUT station with respect to IISC is 12 ± 1 mm/yr towards SW. Besides, we have also examined anomalous changes in the time series of GHUT before, after and during the occurrences of local earthquakes by considering the empirical strain radius; such that, a possible relationship between the strain radius and the occurrences of earthquakes have been explored. We considered seven local earthquakes on the basis of Dobrovolsky strain radius condition having magnitude from 4.5 to 5.7, which occurred from 2007 to 2011. Results show irrespective of the station strain radius, pre-seismic surface deformational anomalies are observed roughly 70 to 80 days before the occurrence of a Moderate or higher magnitude events. This has been observed for the cases of those events originated from the Uttarakashi and the Chamoli seismic zones in the Garhwal and Kumaun Himalaya. Occurrences of short (< 100 days) and long (two years) inter-seismic events in the Garhwal region plausibly regulating and diffusing the regional strain accumulation.

Authors: Atay Enver , Kılınç Suna , Ulfer Gozde , Yigitbasi Turkan , Cakici Cagri , Turan Murat , Ceran Omer , Atay Zeynep
Published: January 2021

Background

There is no data regarding the interrelationships of circulating Makorin Ring Finger Protein-3 (MKRN3), Kisspeptin (KISS1), and Neurokinin B (NKB) concentrations during minipuberty in humans.

Objective

To determine temporal changes in circulating concentrations of MKRN3, KISS1, NKB, and gonadotropins and investigate interrelationships between them in healthy full-term (FT) and preterm (PT) infants during minipuberty period.

Methods

A prospective study of 6-month follow-up performed. Eighty-seven healthy newborns, 48 FT (19 boys/29 girls), and 39 PT (21 boys/18 girls) (gestational age 31–37 weeks), were included. Blood samples were taken at 7 days (D7), 2 months (M2), and 6 months (M6) of age. Serum MKRN3, KISS1, NKB, LH, FSH, total testosterone (TT), and estradiol (E2) concentrations were measured.

Results

Seventy infants completed the study. MKRN3, KISS1, and NKB concentrations were similar in FT girls and boys. PT boys and girls also had similar concentrations of MKRN3, KISS1, and NKB. FT babies had significantly higher NKB concentrations than PT babies at D7, M2, and M6. MKRN3 and KISS1 concentrations do not differ between FT and PT babies. A strong positive correlation was found between MKRN3 and KISS1 at each time point and in all groups. FSH, LH, TT/E2 concentrations decrease while those of MKRN3 and KISS1 have a trend to increase toward the end of minipuberty. No correlation was detected between gonadotropins and MKRN3, KISS1, NKB concentrations.

Conclusion

Strong positive correlation demonstrated between KISS1 and MKRN3 suggests that interrelationship between molecules controlling minipuberty is not similar to those at puberty.
Blowing specific words: verbal charms as material suspended events
Authors: Siragusa Laura , Zhukova Ol’ga Yu.
Published: January 2021

This article undermines the actuality of a strict boundary between language and materiality by presenting verbal charms (puheged,vajhed/pakitasin Vepsian) among Veps, an Indigenous minority group of Northwest Russia. Vepsian verbal charms are ritualized ways of speaking that are customarily used to prompt a change in both human beings and environments in very tangible ways. When observing how they are conceived, distributed, and performed among Veps, the rigid separation between “material” and “immaterial” realms begins to be felt as an artificial construction, since Veps understand that in the act of “blowing” air accompanied by the recitation of “specific words,” human and often non-human agencies join forces to promote changes in people and the environment. This paper engages not only with the academic interest in the material intersections between language and the world (see, Cavanaugh and Shankar 2017; Keane 2008a; Wiener 2013, to name a few), but also aims to reframe the notion of “event” as a transformative and suspended encounter between human and often non-human agencies (Kapferer 2015) and thus deepen our understanding of what living relationally might entail.

Published: January 2021

Nanophotonic engineering of light–matter interaction at subwavelength scale allows thermal radiation that is fundamentally different from that of traditional thermal emitters and provides exciting opportunities for various thermal-photonic applications. We propose a new kind of integrated and electrically controlled thermal emitter that exploits layered metamaterials with lithography-free and dielectric/metallic nanolayers. We demonstrate both theoretically and experimentally that the proposed concept can create a strong photonic bandgap in the visible regime and allow small impedance mismatch at the infrared wavelengths, which gives rise to optical features of significantly enhanced emissivity at the broad infrared wavelengths of 1.4–14 μm as well as effectively suppressed emissivity in the visible region. The electrically driven metamaterial devices are optically and thermally stable at temperatures up to ∼800 K with electro-optical conversion efficiency reaching ∼30%. We believe that the proposed high-efficiency thermal emitters will pave the way toward integrated infrared light source platforms for various thermal-photonic applications and particularly provide a novel alternative for cost-effective, compact, low glare, and energy-efficient infrared heating.

Published: January 2021

The new paradigm of parity-time symmetry in quantum mechanics has readily been applied in the field of optics with numerous demonstrations of exotic properties in photonic systems. In this work, we report on the implementation of single frequency electrically injected distributed feedback (DFB) laser diodes based on parity-time symmetric dual gratings in a standard ridge waveguide configuration. We demonstrate enhanced modal discrimination for these devices as compared with index or gain coupled ones, fabricated in the same technology run. Optical transmission probing experiments further show asymmetric amplification in the light propagation confirming the parity-time symmetry signature of unidirectional light behavior. Another asset of these complex coupled devices is further highlighted in terms of robustness to optical feedback.

The Impact of Five Different Tax Policy Changes on Household Giving in the United States
Authors: Rooney Patrick , Zarins Sasha , Bergdoll Jon , Osili Una
Published: January 2021

About $450 billion were donated to U.S. nonprofits in 2019 according to the most recently available data (Giving USA Foundation 2020). However, despite the increases in charitable dollars, the share of households that donate has been declining: in 2000, 67 percent of American households donated to nonprofits, but in 2016, only 53 percent of American households donated (Indiana University Lilly Family School of Philanthropy 2019). This trend in decreasing share of U.S. households that donate to charitable causes pre-dates the passage of the 2017 Tax Cuts and Jobs Act (TCJA), but could be accelerated by the recent policy changes. TCJA significantly changed federal tax policy and these changes are expected to affect charitable giving (Brill and Choe 2018; Ricco 2018; Rooney et al. 2017). Nonprofit leaders, as well as policymakers, have been exploring additional policy proposals to offset the potential negative impact on charitable giving. This paper investigates the estimated effects of potential policy proposals on charitable giving, donor incidence rates, and Treasury revenue. This study used the Penn Wharton Budget Model (Penn 2019a, 2019b) to run microsimulations of the effects of five tax policy proposals on charitable giving dollars, the number of households that donate, and the forgone Treasury revenue. The five proposals included: a non-itemizer charitable deduction; a non-itemizer charitable deduction with a cap; a non-itemizer charitable deduction with a floor; an enhanced non-itemizer charitable deduction, which provides a higher value deduction for low- and middle-income households; and a non-itemizer non-refundable 25 percent charitable giving tax credit. Of the five policy options analyzed, providing a non-refundable 25% charitable giving tax credit to non-itemizers has the largest positive impact, increasing both the amount of charitable giving dollars ($37 billion in 2018 dollars) and the number of donor households (10.6 million) of the five policy options analyzed. However, it is also the most “expensive” proposal (measured in terms of forgone Treasury revenue) for United States (U.S.) Treasury revenue (−$33.0 billion). Four of the five policy proposals bring in more charitable dollars than are lost in Treasury revenue. Four of the five policy proposals bring in more charitable dollars than were projected to have been lost as a result of TCJA. All five proposals bring in more donor households that were expected to be lost as a result of TCJA. This paper is based on a published report written and researched by [school] in partnership with the Wharton School of Business at the University of Pennsylvania and commissioned by Independent Sector.

Cases of canine poisoning pose a great challenge to pet owners and veterinarians due to incomplete patient history, late/delayed presentation of pets and the large array of poisonous agents. A ten-year retrospective study on canine poisoning cases presented to the Veterinary Teaching Hospital, Abeokuta, Nigeria was conducted. Descriptive statistics were used to characterize animal signalment, mode, month and year of exposure, severity, treatment and outcome. Associations between explanatory demographic characteristics of patients (age, sex and breed) with poison type and route of exposure were determined using a binary logistic regression model. Fifty-two case records with poisoning history and complete data were reviewed. The study population consisted of twenty males and thirty-two females between two months and five years of age. Poisonous agents that were identified included insecticides/acaricides (83%), cleaning products (2%), rodenticides (4%) and snake venom (6%). Poisoning occurred more in Alsatians, especially during the rainy season. No association between the dog demographics with type of poisoning and route of exposure was observed (p>0.05). There were 4 fatalities and 48 recoveries. This study highlights the heterogeneity of poisonous agents, associated clinical signs, treatment and outcome, and the challenges involved in poison control. Standardized approaches for the collection, assessment, integration of poisoning data and risk management is needed.

The goal is to set multiple stages of research to be able to obtain samples of transparent wood of different species and to evaluate them and subsequently to design constructions suitable for the properties of the obtained material. The aim is to be for the constructions of façade systems and beams of composite cross-section, possibly with the focus on “I” section beams made of transparent wood, but different approaches will also be considered. First, the designs will be evaluated and adjusted using suitable software and after, they will be built and experimentally tested. As the technology at the university will not allow the production of full scale models, some models in scale shall be produced and evaluated in Košice during the upcoming months.
Modeling and simulation of capillary ridges on the free surface dynamics of third-grade fluid
Authors: Jose T. Sherin , Patra Kiran Kumar , Panda Satyananda
Published: January 2021

Most of the viscoelastic fluids have deformation while flowing over a heated plate. A typical feature of a thin viscous or viscoelastic fluid is the formation of the capillary ridges over locally heated plates. The creation of such ridges in the thin-film surface can affect the smoothness of the coating. This work particularly concerned the flow of non-Newtonian third-grade fluid over an inclined heated plate and the formation of ridges. The conservation laws associated with free surface and wall boundary conditions model the two-dimensional fluid flow. The long wave approximation of the model results in an equation of evolution to explain the structure of free surfaces. The resulting equation is discretized implicitly using the finite volume method. The obtained results are discussed for different flow parameters that affect capillary ridge emergence on the free surface. Variation in the height of capillary ridges of third-grade fluid is compared with the second-grade fluid and Newtonian fluid flow. We observe, the ridge size gets smaller for the third-grade fluid compared to the Newtonian and the second-grade fluid. Our analysis investigates how the third-grade viscoelastic parameters affect the dynamics of the free surface and the size of the capillary ridge concerning temperature changes and other phenomena of interest.
Comparison and Harmonization of the Locked-Wheel Skid Tester and the Sideway-Force Coefficient Routine Investigation Machine
Authors: McCarthy Ross , Flintsch Gerardo , de León Izeppi Edgar
Published: January 2021

Skid resistance is a characteristic of a pavement surface that is critical to pavement safety. Skid resistance can be measured with different types of equipment, but because of the differences in the system configurations and the testing methods (fixed slip, locked-wheel, sideway-force, and variable-slip), the measured friction characteristics are not the same. To compare the measurements, analysts have attempted to harmonize measurements to a common scale by integrating the effects of macrotexture and slip-speed on skid resistance. Examples of these efforts include the Penn State model, the Rado Model, the Permanent International Association of Road Congresses International Friction Index (IFI), and the Rolling Resistance, Skid Resistance, and Noise Emission (ROSANNE) Skid Resistance Index (SRI). In the United States, skid resistance is traditionally measured with a locked-wheel skid trailer (LWST), but there has been increasing interest in the use of continuous friction measurement equipment. This paper compares friction measured using a LWST ribbed tire and smooth tire with measurements collected with a Sideway-Force Routine Investigation Machine (SCRIM). The first objective is to evaluate the influence of macrotexture on the friction measured with both devices. The second objective is to compare the friction measurements using orthogonal regression (OR) and derive equations for interconversion between both devices. The findings in this paper establish that the LWST ribbed tire and the SCRIM shared similar sensitivity to changes in microtexture, whereas smooth tire was more sensitive to changes in microtexture. The direction of the OR of both devices produced a greater correlation for the SCRIM and ribbed tire than did the smooth tire. The correlation was increased when the measurements with the SCRIM and smooth tire were converted to 60 km/h using the IFI FR60 conversion. The higher correlation using FR60 conversion provides further support for the dependence of smooth tire friction on macrotexture measurements.

Background and objective: Human identification and anthropological evaluation of mass graves are the key step towards scientific documentation and achieving justice. This study aimed to investigate the exhumation, anthropological evaluation, and individual victim identification of a mass grave in Busaya in Samawa governorate. Methods: The investigation included excavation of the graves and identification of the victims. The field study was started after taking testimonies and witnesses for locating the site of graves. The sites were determined, which were excavated according to the scientific standard procedures. Gender determination and age and stature estimation were performed on the remnant skeletons in the laboratory of the medico-legal institute in Erbil. Results: The grave included 93 bodies, 66 (71%) were males, 24 (26%) were possibly males, while the others were not identified because of degradations of the bones. The results of age estimation reported that the number of young bodies under 20 years old were five cases (5.4%), while 53 cases (57%) were young bodies between 20-29 years. The rest were more than 30 years old, except for eight cases that could not be identified. The results of stature revealed that more than half of cases had stature more than 166 cm, while only six cases were less than 155 cm. All the remained bones were recorded in detail for more documentation. Conclusion: These findings described the anthropological evaluation of a large Barzanian mass graves in Busaya desert in the south region in Iraq. The majority (or all) of the victims were males and young people. Keywords: Mass grave; Barzanian victims; Busaya; Exhumation; Identification.
Oligohydramnios and fetal outcome in term pregnancy
Authors: Ibrahim Hazha , Zween Zainab
Published: January 2021

Background and objective: Oligohydramnios is defined as an amniotic fluid index less than 5th centile for gestation. It presents a threat to the fetus and has been correlated with increased risk of intrauterine growth retardation, meconium aspiration syndrome, severe birth asphyxia, low APGAR scores, and congenital abnormalities. It is associated with perinatal morbidity and mortality and maternal morbidity in a significant number of cases. Therefore, early detection of oligohydramnios and its management is important. This study aimed to determine the perinatal and maternal outcomes in oligohydramnios. Methods: This retrospective cohort study was carried out at the Maternity Teaching Hospital in Erbil from March 2018 to March 2019. A total of 300 patients were recruited, including 150 pregnant women with oligohydramnios and 150 with normal amniotic fluid index. Results: There was a significant difference between the oligohydramnios group and the comparison group in relation to parity and gestational age. Oligohydramnios was more among primigravids. The rate of cesarean section was higher in oligohydramnios group compared to the comparison group. Intrauterine growth retardation among oligohydramnios group was 13%. Oligohydramnios was associated with birth weight <2500 gm (21.3%). Conclusion: Antepartum diagnosis of severe oligohydramnios at term was associated with an increased cesarean section rate, a higher rate of admission of neonatal care unit, and low birth weight. Therefore, antepartum oligohydramnios is associated with increased perinatal morbidity and mortality. Keywords: Amniotic fluid index; Maternal outcome; Fetal outcome; Oligohydramnios.
Motor Interference, But Not Sensory Interference, Increases Midfrontal Theta Activity and Brain Synchronization during Reactive Control
Authors: Kaiser Jakob , Schütz-Bosbach Simone
Published: January 2021

Cognitive control helps us to overcome task interference in challenging situations. Resolving conflicts because of interfering influences is believed to rely on midfrontal theta oscillations. However, different sources of interference necessitate different types of control. Attentional control is needed to suppress salient distractors. Motor control is needed to suppress goal-incompatible action impulses. While previous studies mostly studied the additive effects of attentional and motor conflicts, we independently manipulated the need for attentional control (via visual distractors) and motor control (via unexpected response deviations) in an EEG study with male and female humans. We sought to find out whether these different types of control rely on the same midfrontal oscillatory mechanisms. Motor conflicts, but not attentional conflicts, elicited increases in midfrontal theta power during conflict resolution. Independent of the type of conflict, theta power was predictive of motor slowing. Connectivity analysis via phase-based synchronization indicated a widespread increase interbrain connectivity for motor conflicts, but a midfrontal-to-posterior decrease in connectivity for attentional conflicts. For each condition, we found stronger midfrontal connectivity with the parietal region contralateral to, rather than ipsilateral to, the acting hand. Parietal lateralization in connectivity was strongest for motor conflicts. Previous studies suggested that midfrontal theta oscillations might represent a general control mechanism, which aids conflict resolution independent of the conflict domain. In contrast, our results show that oscillatory theta dynamics during reactive control mostly reflect motor-related adjustments.

SIGNIFICANCE STATEMENTHumans need to exercise self-control over both their attention (to avoid distraction) and their motor activity (to suppress inappropriate action impulses). Midfrontal theta oscillations have been assumed to indicate a general control mechanism, which help to exert top-down control during both motor and sensory interference. We are using a novel approach for the independent manipulation of attentional and motor control to show that increases in midfrontal theta power and brainwide connectivity are linked to the top-down adjustments of motor responses, not sensory interference. These findings clarify the function of midfrontal theta dynamics as a key aspect of neural top-down control and help to dissociate domain-general from motor-specific aspects of self-control.
Acne: Advocating for holistic support
Authors: Riahi Aryan , Jung David
Published: January 2021

As health practitioners, having a holistic approach to patients is critical. Patients are a complex interplay of physical, emotional, and social well-being. Limiting treatments to only some of these domains will inevitably yield suboptimal health and reduced quality of life. Thus, it is imperative that we advocate for acne-prone individuals so that they can receive the well-rounded care they deserve.
The Implication of e-WoM Communication on Customer Preference and Purchase Decision of Electronic Gadgets

Published: January 2021

This study aims to analyze the implications of e-WoM components (intra-personal ties, homophile, credibility) on consumer purchasing decisions both directly and through mediating consumer preferences. Previous experience of consumer purchases conveyed by word of mouth can be a preference for other consumers in buying products or services. The development of digital communication makes electronic Word of Mouth (e-WoM) play an important role in influencing consumer preferences, especially for those who have to make purchasing decisions for products with many features such as gadgets. A total of 300 questionnaires were distributed around Jakarta using simple random sampling and obtained 102 complete responses from respondents. Data analysis was performed using descriptive statistical methods, correlational and multiple regression with the help of SPSS software. The results showed that the gadget purchase decision was partially influenced by consumer purchasing preferences and credibility sources, but this purchase preference was not as dominant as the credibility source. Gadgets are designed unusual and have many advanced technological features compared to conventional products, therefore the results of this study may not be valid for products outside of the gadget. Further research is needed whether e-WoM has the same influence on consumer purchasing decisions of conventional products.
Market Competition and Agency Problem: a Study in Indonesian Manufacturing Companies
Authors: Nugroho Ahmad Cahyo , Stoffers Jol
Published: January 2021

This research examines the relationship between firm investment and market competition, market position and market position as market leader. This study analyzes agency problems in manufacturing companiesâ€™ investment decisions by considering market competition, since market competition is considered as one of essential factor that affect the firm investment. Further, high competition signals companyâ€™s increased investment, that leads to business efficiency. Investment decisions are important for companies to survive, and more competitive companies are likely to conduct more risky activities, especially regarding capital expenditures for investments. This study uses the dynamic panel data method, which includes annual financial report of 100 listed manufacturing companies on IDX from 2007 to 2016. The companies were selected after sorting using several criteria, such as completeness of financial report and being registered on IDX during the period. Results suggest that leverage improves management control functions, and competition increases a companyâ€™s investments to maintain its position in the market. Competition is not strengthened or weakened by sales growth and there are indications of herding behavior following market leaders.
Social Performance of Rural Bank: Impact of Commercialization Factors

Although social performance is an important target in islamic rural bank, this performance is constrained by various factors of commercialization. This study examined the impact of commercialization factors covering profitability, regulation, and competition on the social performance of rural bank. This research was quantitative that based on a survey on fifty units of rural banks in West Sumatera province of Indonesia from 2016 to 2018. The secondary data collected from the publication of financial services authority and other financial documents at rural banks then analyzed with panel data regression. The findings of this research showed that profitability and competition influenced the social performance, meanwhile regulation could not predict the achievement of social performance.Â  This finding reinforced the previous studies which identified the impact of some commercialization indicators towards the achievement of social performance but there was no regulationâ€™s impact on social performance.Â  The impact of regulation which was originally expected to be able to strengthen the social responsibility mission of rural banks evidently did not stimulate the increase of social performance.

Published: January 2021

This study aims to examine Technology Acceptance Model (TAM) on the implementation of E-Government. Data for this study were collected through a questionnaire survey on the people of Malang City who have used E-Government services. Structural model analysis was performed using smartPLS. The results showed that intention was the main determinant of the use of E-Government services. The determining factor of intention to use E-Government services is positive attitude towards E-Government. Other factors such as system quality, its ease of use, and quality of information do not affect peopleâ€™s interest in using E-Government services. In other words, E-Government application developed by the City Government has been deemed not easy enough to be applied and not informative enough to meet the information needs of the community. This is a challenge for the City Government to be able to improve and develop the quality of systems and information from its E-Government services so that people are increasingly interested in applying it, for the realization of Malang as a smart city.

The digital economy is a new economic era and social form of human society after the industrial revolution and information economy. It creates the free time and free activities needed for human development, provides an exploratory plan for the modern society to move toward the sharing economy, and brings many development relations issues that we need to face and examine objectively. From the perspective of human development, this paper deeply discussed the development progress of digital economy through specific cases. We believe that the digital economy breaks the rigid and rational world of humankind based on causality but makes more possible correlations become the philosophical support behind the digital economy model, thereby creating more possibilities for.
