Authors: Kim Jin Sung , Kim Duk Ho , Lee Dong Wuk , Kim Sundeok
Published: November 2021

Purpose: We aimed to investigate the benefit of a screening tool in selecting head-injured children who can potentially cooperate with computed tomography (CT).Methods: The study population consisted of head-injured children aged 36 months or younger who visited the emergency department (ED) and underwent CT from January 2013 through December 2020. Procedural sedation and analgesia (PSA) using per os chloral hydrate or per rectal thiopental was implemented to children presumed less cooperative for CT as per a clinical screening tool for cooperative candidates for CT (e.g., ability to lie still on bed for 10 seconds without a guardian). According to the PSA and the first attempt success of CT, we compared baseline characteristics, CT findings, clinically important traumatic brain injury, ED length of stay (EDLOS), and ED disposition.Results: Among the 247 children, PSA was used in 102 (41.3%). The PSA group showed a higher proportion of 3-36 months of age (PSA, 96.1% vs. non-PSA, 82.8%; P = 0.001) and longer median EDLOS (PSA, 127.0 [interquartile range, 101.0-172.0] vs. non-PSA, 85.0 minutes [63.0-130.0]; P < 0.001). The number of children undergoing the first attempt success was 213 (86.2%) without a difference in both groups (PSA, 84.3% vs. non-PSA, 87.6%; P = 0.645). In the 213 children, the implementation of PSA was associated with longer median EDLOS (PSA, 121.0 [99.0-156.0] vs. non-PSA, 77.0 minutes [60.0-122.0]; P < 0.001). In the non-PSA group (n = 145), the first attempt failure was associated with the presence of skull fracture (success, 7.1% vs. failure, 27.8%; P = 0.009).Conclusion: This study suggests a potential benefit of the screening tool in selecting cooperative candidates for CT, i.e., those who could forgo PSA using oral chloral hydrate or per rectal thiopental, in young children with head injury.

Published: November 2021

The issues concerning deficit spending have been a major concern in macroeconomic policies. Each country has a different method to solve the problems, including by devising appropriate deficit spending policies. This study investigates the effect of deficit spending in Indonesia. The effect of deficit management is seen from the sources to finance budget deficit, the efforts that are made, and the ability to contribute to the economy. Another research objective is to identify the magnitude of the effect of deficit spending and its effect on the national economy. This study attempts to explain that the applied model is able to determine the factors that contribute to deficit spending in Indonesia. The findings of this study reveal that both in the short- and long-run, external debts have a positive and significant effect on deficit spending. On the contrary, the economic growth and inflation rate have no significant effect on deficit spending.

Authors: Panjaitan Roymon , Moonti Agustinus , Adam Echan
Published: November 2021

The digital economy for MSMEs still possesses complex problems in the debate over technology readiness and competitive digital capabilities. The increase of dynamic product innovation changes is only effectively supported by digital value resonance. Addressing this issue, this research aims to explore the readiness of technology and the ability to compete digitally for innovative products through the resonance of digital value, especially for multi-business businesses. The data were collected from 170 respondents of small and medium-sized businesses through questionnaires. SEM-PLS techniques were used to analyze the data with a path mediated by digital value resonance on product innovation. The results showed that the resonance of digital value successfully mediated the relationship of technological readiness and digital competing capabilities, as well as direct links to the improvement of innovative products. Digital consumer habits also successfully strengthened the relationship of technological readiness and digital competing capabilities on the resonance of digital value. The advantages of this research lie in the synthesis of proposed digital value resonance variables from the results of resource-based view theory propositions in bridging the previous researcher gaps and contributing as a conceptual novelty model that can personalize digital value in the level of competition and increase MSMEs innovation products.

Authors: Ninglasari Sri Yayu
Published: November 2021

Today’s modern civilization has resulted in the crucial role of technology in human life, including financial matter. Integrating Technology Acceptance Model (TAM) and Theory of Planned Behavior (TPB), this study sheds some light on the determinants of Muslim millennials’ intention in performing zakat payment using Financial Technology (Fintech). An online questionnaire survey was conducted to gather the required data from a group of Indonesian Muslim millennials. Employing purposive sampling technique, the sample consisted of 200 respondents. The data were analyzed with the assistance of Structural Equation Model - Partial Least Square (SEM-PLS). The results demonstrated that perceived ease of use and perceived usefulness positively and significantly affected the respondents’ attitudes. Moreover, attitudes, subjective norms, and perceived behavioral control significantly affected the intention of using Fintech to perform zakat payment. The results further revealed that there was no direct influence between perceived ease of use and perceived usefulness on the respondents’ intention to use Fintech. However, it had an indirect effect by the mediation of attitude variable. As a theoretical implication, this study contributes to the literature enhancement in the discourse of TAM and TPB models in zakat context. Practically, it assists zakat management institutions recognize the Muslim millennial community and develop digital zakat payment platforms.
Associations among leaf developmental stability, canalization and phenotypic plasticity in response to population density in Abutilon theophrasti under contrasting soil conditions at different growth stages
Authors: Wang Shu , Zhou Dao-Wei
Published: November 2021

Most studies on animals have conducted comparative studies to deduce the
possible relationships among developmental stability, canalization and
phenotypic plasticity, there is a lack of direct evidence in plants,
which should be better study materials. To investigate the correlations
among developmental stability, canalization and plasticity in plants, we
conducted a field experiment with Abutilon theophrasti, by subjected
plants to three densities under infertile vs. fertile soil conditions,
and measured leaf size, leaf fluctuating asymmetry (FA), and calculated
coefficient of variation among leaves within individuals (CVleaf) and
among individuals (CVin) and relative plasticity (PIrel) and its degree
in leaf size at three growth stages, to analyze the responses of their
correlations to density and how they may vary with soil conditions or
growth stages. Results showed a decrease of FA, CVleaf and PIrel and an
increase of CVin in leaf size, with increased density. In most cases,
there were no correlations among these variables, but negative
correlations between CVin and PIrel, positive correlations between FA
and PIrel at high density and/or in fertile soil, in infertile soil. It
suggested that higher FA may indicate the state of faster growth rather
than an indicator of environmental stresses; there are correlations
among developmental stability, canalization and plasticity, which may be
complex, affected by other factors. The loss of developmental stability
may be beneficial for plant response to environmental stresses, while
decreased canalization can be either disadvantageous or advantageous,
depending on that the size variation results from an increase or
decrease of smaller individuals, and whether its correlations with other
variables reflect beneficial or adverse environmental effects.

Authors:   , Ibarhiam Saham F.
Published: November 2021

In the current study, the waste stones and rachis obtained from Barhee and Medjool dates palm trees were characterized on a laboratory scale and their potential as biomass feedstock were investigated. The proximate, ultimate, structure/composition and thermo-gravimetric analysis experiments were conducted to characterize the selected biomass materials. The results showed that the Medjool and Barhee stones are a promising biomass feedstock as they have high volatile and fixed carbon contents with low ash content. Moreover, they have high carbon and nitrogen contents with a very high cellulose contents reaching up to 66% in the case of Barhee stones. The thermo-gravimetric analysis showed that the decomposition of Barhee and Medjool stones can be completed below 420 °C; while it can be completed below 360 °C for Barhee and Medjool rachis under thermo-gravimetric pyrolysis analysis. Based on the TGA results obtained, slow pyrolysis experiments for the stones and rachis feedstock materials were conducted. Among the four slow pyrolysis trials, maximum yield for bio-oil of 21.54% was achieved when Barhee rachis was used, while Medjool rachis produced the least value. Characterization and analysis of the bio-oil extracted from the pyrolysis experiments showed the superiority of the bio-oil from Barhee stone as it has the highest heating value. The gas chromatography mass spectrometry analysis showed that phenol, furfural and benzoic acid are the main components of the bio-oil obtained from the date palm rachis samples while d-allose, furfural, 5-methyl 2-furancarboxaldehyde, and dodecanoic acid are the main components of the bio-oil extracted from the date palm stones. The opportunities of exploitation of renewable energy with solar, biomass and biofuels resources in the Middle East, are also reviewed in detail in this work. The techno-economic analysis for the concentrating solar power plants installed in the Middle East showed promising potential from the economic and technical point of view.

It is shown that the rheological and tribological properties of the samples have a complicated dependence, which is determined by inhomogeneity of the system. The paper takes into consideration the influence of the friction coefficient of material and the viscosity of its melt on energy costs during processing by injection molding or extrusion

The article presents the resultsof mathematical modeling of the energy-dynamic processes of a wind farm which includes a battery energy storage system (BESS). The dependence between load capacity and energy generation capabilities of the active set of a wind power plant taking into account the energy capacity of BESS has been determined. A mathematical model of the BESS has been developed. The elaborated model is compared with two other models: a black box module and a model based on equivalent circuit model. The application of the developed model provides an opportunity to optimize the energy capacity of BESS for the specified parameters and modes of operation of the wind power plant. Using the obtained results expands the possibilities of the adequate management of energy-dynamic modes of energy systems with renewable energy sources, provides mitigation of transition processes in conditions of insufficient or excessive wind speeds and consumer loads.

Koronaviruspandemian rajoittamiseen liittyvät ensimmäiset toimenpiteet ja seuraukset kohdistuivat erityisesti ikääntyneisiin. Sosiaali- ja terveyspalvelujen resursseja kohdennettiin uudelleen ja osa palveluista suljettiin. Samanaikaisesti lähikontaktien välttäminen vaikeutti omaisten tarjoamaa apua. Selvitimme puolistrukturoitujen haastattelujen (N=16) laadullisen teema-analyysin avulla, miten yksityisessä kodissa tai tehostetussa palveluasumisessa asuvien ihmisten avun saaminen muuttui ja miten he suhtautuivat lähikontaktien välttämiseen sekä mahdollisiin muutoksiin avun saamisessa. Kahdeksassa haastattelussa kerrottiin muutoksia tapahtuneen, seitsemässä taas ei. Yhden asumispalveluissa asuvan henkilön tilanne jäi epäselväksi. Jaoimme kuvaukset kolmeen teemaan. Neutraalit kuvaukset eivät olleet myönteisiä eivätkä kielteisiä, ja ne liittyivät yleensä vähäisiin muutoksiin. Sopeutumista kuvasi se, että henkilöt pyrkivät ilmaisemaan mahdollista haittaa aiheuttaneiden muutosten lisäksi jotain myönteistä ja keksimään uusia toimintatapoja. Huolta aiheutti epäselvyys hoidon järjestämisessä tai järjestämistavoissa sekä ahdistus läheisten tapaamattomuudesta. Kotona asumista suosiva hoivapolitiikka on varautunut puutteellisesti äkillisiin kriisitilanteisiin etenkin niiden kohdalla, jotka ovat huomattavassa määrin omaisten avun varassa. Tämä joukko tarvitsisi joustavampia avunsaantimuotoja kuin koronapandemian yhteydessä on pystytty suosittelemaan tai tarjoamaan.
