Regional differences in welfare and well-being in the European Union
Authors: Nedelka Erzsébet
Published: June 2020

In the study, it is analysed whether the groups of countries formed in the 1990s and 2000s still fit well to the model represented at that time, and whether the countries of the Mediterranean, Western Europe, Central and Eastern Europe still separate from each other based on the welfare and well-being indicators. Factor analysis and a new indicator, the welfare factor together with well-being indicators were used in cluster analyses. The three years data and the clusters based on them were analysed. It was pointed out that before the crisis the states representing the Northern model were indeed separate, and liberal and conservative states appeared in a group but at the same time still separately, and the Mediterranean countries were mixed with the post-socialist countries. After the crisis, the northern states merged with the liberal and conservative welfare states, and the Mediterranean countries formed a mixed group with the post-socialist states. Greece was separated from each group of countries. 2018 brought even greater changes. Not only Greece but also Slovenia and Czech Republic isolated, and a more composite category was formed from the other Mediterranean countries and post-socialist countries. Taking income and poverty indicators out, it was examined whether the states ranked in each model separated from each other according to them. The result was, however, again a diverse group. Therefore, based on the indicators, it was not possible to clearly prove the Esping-Andersen, Sapir and Baltic theory in today’s economic environment (Esping-Andersen, 1991; Sapir, 2006; Baltic, 2011).
Personalbezogene Herausforderungen in der Organisationsentwicklung von KMU :
Authors: Breuer Stefan
Published: June 2020

Die Unternehmensführung gilt aufgrund der immer dynamischer werdenden Entwicklungen in der Unternehmensumwelt heute als so herausfordernd wie niemals zuvor. Die hieraus resultierenden Anpassungs- und Veränderungsnotwendigkeiten in der Organisation der Unternehmen lassen dem wissenschaftlichen Themengebiet der Organisationsentwicklung eine immer stärker werdende Bedeutung zukommen. Da dieses Themenfeld maßgeblich von den Mitarbeitern der Unternehmen beeinflusst und getragen wird, steht das Erzielen von Erkenntnissen von und in Bezug auf die Mitarbeiter eines Unternehmens im zentralen Fokus der Unternehmensführung. Die Mitarbeiterbefragung gilt somit als wichtiges Werkzeug im Rahmen der Organisationsentwicklung. Die Ergebnisse einer Mitarbeiterbefragung sollen das Unternehmen und die Unternehmensführung in die Lage versetzen, Veränderungsnotwendigkeiten im Unternehmen zu erkennen und folglich entsprechende Veränderungsprozesse zu initiieren. Hierdurch wird die besondere Bedeutung von Mitarbeiterbefragungen deutlich. Der Mittelstand, welcher insbesondere in Zukunfts- und Wachstumsmärkten durch die zuvor beschriebene Dynamik vor besonderen organisatorischen Herausforderungen steht, gilt hier als betrachtungswürdig. Mittelständische Unternehmen gelten zwar grundsätzlich als wettbewerbsfähig, sind in Ihrer organisatorischen Entwicklung allerdings oftmals aufgrund der begrenzt zur Verfügung stehenden administrativen Ressourcen und der fehlenden strategischen Ausrichtung rückständig. In der vorliegenden Untersuchung wird der Einsatz der Mitarbeiterbefragung zum Zwecke der Organisationsentwicklung am Beispiel eines mittelständischen deutschen Unternehmens dargestellt.

Authors: Malik Amarila , Yuliantie Elita , Suprahman Nisa Yulianti , Linardi Theresa , Widiyanti Angelina Wening , Haldy Jeanita , Tjia Catherine , Takagi Hiroshi
Published: June 2020

Background:

Bacteriocins (Bac1, Bac2, and Bac3) from Weissella confusa MBF8-1, weissellicin-
MBF, have been reported as potential alternative substances as well as complements to the existing
antibiotics against many antimicrobial-resistant pathogens. Previously, the genes encoded in the
large plasmid, pWcMBF8-1, and the spermicidal activity of their synthetic peptides, originally discovered
Indonesia, have been studied. Three synthetic bacteriocins peptides of this weissellicin-MBF have
been reported for their potential activities, i.e. antibacterial and spermicidal.

Objective:

The aim of this study was to construct the recombinant Bacteriocin (r-Bac) genes, as well as
to investigate the gene expressions and their functional analysis.

Method:

Here, the recombinant Bacteriocin (r-Bac) genes were constructed and the recombinant peptides
(r-Bac1, r-Bac2, and r-Bac3) in B. subtilis DB403 cells were produced on a large scale. After purification,
using the His-tag affinity column, their potential bioactivities were measured as well as their
antibacterial minimum inhibitory concentrations against Leuconostoc mesenteroides and Micrococcus
luteus, were determined.

Results:

Pure His-tag-recombinant Bac1, Bac2, and Bac3 were obtained and they could inhibit the
growth of L. mesenteroides and M. luteus.

Conclusion:

The recombinant bacteriocin could be obtained although with weak activity in inhibiting
gram-positive bacterial growth.

Authors: Wande Dickson P. , Cui Qin , Chen Shijie , Xu Cheng , Xiong Hui , Yao Jing
Published: June 2020

A unique and pleiotropic polymer, d-alpha-tocopheryl polyethylene glycol succinate (Tocophersolan),
is a polymeric, synthetic version of vitamin E. Tocophersolan has attracted enormous
attention as a versatile excipient in different biomedical applications including drug delivery systems
and nutraceuticals. The multiple inherent properties of Tocophersolan allow it to play flexible roles in
drug delivery system design, including excipients with outstanding biocompatibility, solubilizer with
the ability to promote drug dissolution, drug permeation enhancer, P-glycoprotein inhibitor, and anticancer
compound. For these reasons, Tocophersolan has been widely used for improving the bioavailability
of numerous pharmaceutical active ingredients. Tocophersolan has been approved by stringent
regulatory authorities (such as the US FDA, EMA, and PMDA) as a safe pharmaceutical excipient. In
this review, the current advances in nano-based delivery systems consisting of Tocophersolan, with
possibilities for futuristic applications in drug delivery, gene therapy, and nanotheranostics, were systematically
curated.

Authors: Elhady Heba A. , Al-Shareef Hossa F.
Published: June 2020

Background and Objective:

Due to the well-documented anti-proliferative activity of
2-thiohydantoin incorporated with pyrazole, oxadiazole, quinazoline, urea, β-naphthyl carbamate and
Schiff bases, they are noteworthy in pharmaceutical chemistry.

Methods:

An efficient approach for the synthesis of a novel series of 2-thiohydantoin derivatives incorporated
with pyrazole and oxadiazole has proceeded via the reaction of the acyl hydrazide with
chalcones and/or triethyl orthoformate. Schiff bases were synthesized by the reaction of the acyl hydrazide
with different aromatic aldehydes. Moreover, Curtius rearrangement was applied to the acyl
azide to obtain the urea derivative, quinazoline derivative, and carbamate derivative.

Results:

The synthesized compounds structures were discussed and confirmed depending on their
spectral data. The anticancer activity of these heterocyclic compounds was evaluated against the breast
cancer cell line (MCF-7), where they showed variable activity. Compound 5d found to have a superior
anticancer activity, where it has (IC50 = 2.07 ± 0.13 μg/mL) in comparison with the reference drug
doxorubicin that has (IC50 = 2.79 ± 0.07 μg / mL). Then compound 5d subjected to further studies such
as cell cycle analysis and apoptosis. Apoptosis was confirmed by the upregulation of Bax, downregulation
of Bcl-2, and the increase of the caspase 3/7percentage.

Conclusion:

Insertion of pyrazole, oxadiazole and, quinazoline moieties with 2-thiohydantoin moiety
led to the enhancement of its anti-proliferative activity. Hence they can be used as anticancer agents.

The Autobiographical Dimension of Brainy Books
Authors: Schmitt Arnaud
Published: June 2020

This article purports to explore the autobiographical dimension of a recent publishing phenomenon, brainy books. It’s my contention that these books display a constant dialectic tension between their source (academic research) and their target (non-academic readers), and one way of reconciling both sides consists in resorting to rhetorical strategies in order to make their research more accessible. One of these strategies is openly autobiographical. Through two case studies—Daniel Kahneman’s Thinking, Fast and Slow (2011) and Paul Dolan’s Happiness by Design (2014)—I study the various functions of this autobiographical dimension: perlocutionary, contextualizing, illustrative and finally autobiographical beyond functionality. It’s my overall aim to demonstrate that the authors’ choice to include personal anecdotes or even confessions in books primarily meant to spread knowledge to a larger audience makes brainy books a fascinating subject for life writing studies.

Authors: Polo Rojas José Francisco , Niño Guerrero María Alejandra
Published: June 2020

En este artículo se presentan los resultados de una investigación realizada desde el año 2017, que surge ante la preocupación de los maestros por los retos y desafíos de la práctica pedagógica en el área de Ciencias Sociales. La búsqueda de respuestas pedagógicas y didácticas, permitieron determinar las correlaciones que existen entre los estilos de enseñanza y aprendizaje de los maestros y los estilos de aprendizaje y desempeño académico en el área de Ciencias Sociales de estudiantes de básica secundaria y media académica de una institución educativa pública de la ciudad de Sincelejo, mediante la utilización de los cuestionarios CEE, CHAEA y CHAEA Junior. Los resultados dan cuenta de que los maestros del área de Ciencias Sociales, no tienen estilos de aprendizaje puros, también orientan el área con características muy variadas haciendo uso de los distintos estilos de enseñanza y no necesariamente enseñan como ellos aprenden. Por su parte, los estudiantes educación básica no presentan estilos puros, predominan el estilo Teórico – Reflexivo Pragmático. En la media académica, los estudiantes aprenden con los cuatro estilos propuestos por Alonso, Gallego y Honey (1994). Entre estilos de enseñanza y estilos de aprendizaje de los maestros, se encontró una correlación alta significativa entre el estilo de enseñanza abierto y el estilo de aprendizaje reflexivo y los estilos de enseñanza de los maestros de Ciencias Sociales no se emparejan adecuadamente con los estilos de aprendizaje de los estudiantes. De igual forma, el estilo de aprendizaje del estudiante está relacionado directamente con su desempeño académico.

mHealth Apps as Effective Persuasive Health Technology: Contextualizing the “Necessary” Functionalities
Authors: McLean Allen
Published: June 2020

Persuasive health technology (PHT) is any technology purposely designed to influence, reinforce, change, or shape health-related attitudes or behaviors. Behavioral interventions can be developed for the purpose of maintaining or improving a person’s health status. Delivering behavioral interventions via PHTs is a promising approach for encouraging healthy behaviors among individuals and populations. Important attributes of all PHTs include their functionalities. A functionality refers to any useful features, functions, capabilities, or technologies associated with computer hardware or software. Creating effective PHTs requires a deliberate selection of appropriate functionalities for supporting specific behavioral interventions. The number and types of functionalities necessary to create an effective PHT will be specific to the context of each project, influenced by project objectives, stakeholder goals, behavioral interventions, and a variety of real-world constraints. Selecting appropriate functionalities can be challenging. Fortunately, there are frameworks and models developed specifically for guiding the design of PHTs. The Persuasive Systems Design model describes 4 categories, and 28 design principles for creating effective persuasive interventions. These same design principles could also be useful for guiding the selection of appropriate functionalities.

UNSTRUCTURED

DattaMeghe Institute of Medical Sciences has been declared as Deemed to be University [DMIMS (DU)] under section 3 of UGC Act, 1996 in the year 2005. The University examinations are conducted as per the rules, regulations and guidelines issued by the various Apical councils of India from time to time. The first University exam was conducted in the year 2006. DMIMS (DU) has initiated various reforms by its own in assessment and evaluation process based on needs. For any system to thrive, it needs to be constantly upgraded and critically evaluated. Therefore, a study is undertaken with this in mind and thereby aimed at evaluation and validation of the assessment and evaluation reforms formulated and implemented at DMIMS (DU) since its inception (year 2006).Need analysis for the assessment and evaluation reforms will be carried out on the basis of feedbacks and reports received from respective stakeholders (Students, Faculty and External examiners) from time to time. Outcome analysis of the Feedbacks and reports will be done subsequently after the implementation of the assessment and evaluation reforms. Further based on the outcome analysis, reforms will be validated into following parameters: Objectivity, Responsiveness, User friendliness, Residual component (not covered in above 3 parameters)and a satisfactory index will be derived. If satisfactory index for reform is 100%, it will be concluded that reforms are well received and good to excellent in nature. Total 33 assessment and evaluation reforms have beenimplemented since year 2006. These reforms will be categorised into Pre-Examination (n=18), On Site Examination (n=05) and Post Examination (n=10), and in each category, they will befurther classified into academic (Total =15) and administrative (Total = 18) on the basis of their domain for the ease of structuring and implementation.All the 33 reforms will be validated on the basis of defined parameters.

Effect of Microwave Pretreatment on Gaharu Essential Oil Using Hydrodistillation Method
Authors: Che Radzi Nurhaslina , Kasim Filzah Anati
Published: June 2020

Gaharu wood produces an expensive essential oil due to its fragrance and chemical compounds. Normally, the black color wood is used for the extraction of oil because it contains high resin. However, the cost of this resinous wood is very expensive. Therefore, in this study, the raw material with low resin content (identified by the white color of the wood) will be used for the extraction of oil. However, hydrodistillation alone will not produce satisfactory volume. Thus, pretreatment is needed to enhance the amount of essential oil. This paper aims to investigate the effect of microwave pretreatment on gaharu essential oil extraction using the hydrodistillation method for the lower grade wood. The gaharu wood was pre-treated with microwave irradiation power of 800 kW at three different durations which were 1, 2 and 3 min. Later, extraction was performed using the hydrodistillation method for 30 h. The chemical composition of the oil was analyzed using gas chromatography-mass spectrometry (GCMS). The results show that microwave pretreatment produced higher yield (0.0379 wt.%) of gaharu essential oil compared to the extraction of the non-pretreated wood (0.0286 wt.%) in which the increase was 24.55%. The three minutes pretreatment time produced the largest amount of oil (0.0877 wt.%). The outcomes of this study indicated the increase of chemical components of gaharu essential oils such as (+)-Epi-bicyclosesquiphellandrene, gurjunene, α-farnese, estragole, guaiene, valencene, spathulenol, α-cubebene and (-)-Spathulenol in the extraction of the pre-treated wood compared to the non-pretreated one.

Authors: Oramahi Hasan Ashari , Yoshimura Tsuyoshi , Rusmiyanto Elvi , Kustiati Kustiati
Published: June 2020

In this study, the Box-Behnken Design (BBD) was employed to investigate the effects of wood particle size, pyrolysis temperature, and pyrolysis time on the production of wood vinegar from Indonesia “bengkirai” wood (Shorea laevis Ridl). Characterization of wood vinegar was conducted by gas chromatography-mass spectrometry (GC-MS). Three variable designs consisting of wood particle size (2.00, 2.38, and 3.36 mm), pyrolysis temperature (350, 400, and 450 °C), and pyrolysis time (105, 120, and 135 min) were employed in a BBD response surface methodology (RSM-BBD). RSM-BBD results suggested that maximum wood vinegar yield would be obtained with a wood particle size of 3.85 mm, pyrolysis temperature of 400 °C, and pyrolysis time of 93 min. In addition, the mathematical model indicated the maximum wood vinegar yield would be 30.31%. The main compounds in wood vinegar were acetic acid, 1-hydroxy-2-propanone, furfural, 2,3-pentanedione, phenol, 2-methoxy phenol, 2-methoxy-4-methyl phenol, 2,6-dimethoxy phenol, and 1,2,4-trimethoxybenzene.

Authors: Happyana Nizar , Hermawati Elvira , Syah Yana Maolana , Hakim Euis Holisotan
Published: June 2020

In this work, 1H NMR analysis, along with a chemometrics approach, had been applied for investigating metabolite profiles of Indonesian roasted Robusta coffees obtained from Lampung and Aceh. In total, 24 compounds had been successfully detected in the 1H NMR spectra of the Robusta coffee extracts. Concentrations of some identified metabolites present in the coffees were determined by the quantitative 1H NMR technique. Orthogonal projection to latent structure-discriminant analysis (OPLSDA) was used as a primary method for the chemometric approach. OPLSDA had classified clearly the Robusta coffee samples corresponding to their origin. Loading plot and S-plot of the OPLSDA revealed characteristic metabolites for each Robusta coffee. The results indicated that quinic acid, mannose, arabinoses, and acetic acid were an important discriminant compound for Lampung Robusta coffees. Meanwhile, lipids, lactic acid, and 5-caffeoylquinic acid were found as characteristic metabolites for Aceh Robusta coffee. This report provided knowledge about the chemical composition of Lampung and Aceh Robusta coffees and shed more light on the diversity of Indonesian Robusta coffees. Furthermore, it confirmed that 1H NMR analysis coupled with chemometrics was a powerful method for evaluating and classifying metabolite profiles of the roasted Robusta coffees.

Published: June 2020

In this study, epoxy coatings made up from petroleum-based epoxy resin mixed with two different types of palm oils were prepared and compared. The commercial epoxy resin based on diglycidyl ether of bisphenol A (DGEBA) were formulated with epoxidized unripe palm oil (EPO) and another one with epoxidized used cooking oil (ECO) at four different ratios (0:100, 10:90, 20:80 and 30:70). The EPO and ECO were prepared through generated in situ of performic acid (HCOOH) and hydrogen peroxide (H2O2) by a fixed molar ratio of 1:5:4 mol/mol (EPO/ECO: HCOOH:H2O2). The reaction took place at constant temperature (45 °C) with continuous stirring for 150 min to obtain 95.5% oxirane conversion with 90.0% yield. The EPO and ECO were characterized by using Fourier Transform Infrared (FTIR) spectroscopy analysis. X-Cut and Cross-Cut methods were used in the test performance of adhesion strength. The results obtained from adhesion test for EPO were good as the coatings only experienced small trace of peeling. On the other hand, only minimal performances were obtained from the ECO coated metal. This was due to the presence of oxirane in EPO as compared to that of in ECO. EPO has a potential to replace petroleum-based resin in epoxy coating formulation according to its remarkable performances.

Synthesis of cobalt-doped zirconium titanate (Co-doped ZrTiO4) as a potential photocatalyst with visible-light-response had been conducted. Materials used in this research were titanium tetraisopropoxide (TTIP) as a precursor of TiO2, ZrO2 as another semiconductor for coupling, and CoSO4·7H2O as the source of cobalt dopant. The composite was prepared by the sol-gel method with various cobalt contents and calcination temperatures. Composites with various Co dopant contents (0, 1, 3, 5, 7, and 9% (Co wt./Ti wt.)) were calcined at 500 °C for 4 h. In addition, the composite with 5% of dopant content was calcined at 700 and 900 °C to observe the influence of calcination temperature. All samples were characterized by using X-ray powder diffraction method (XRD), Fourier-transform infrared spectroscopy (FTIR), specular reflectance UV-Vis spectroscopy (SRUV), and scanning electron microscopy equipped with X-ray energy dispersive spectroscopy (SEM-EDS). Co-doped ZrTiO4 with the lowest bandgap (2.94 eV) was achieved in a sample containing 3% of cobalt content calcined at 500 °C.

Recently, Unmanned Aerial Vehicle (UAV) becomes a popular and interesting technology for researchers and academics because it has high potential to be implemented in various fields. The UAV operation is managed by a Ground Control Station (GCS) on which requires a communication system to send control signals and acquire data collected by sensors on UAV. The longer the UAV's flying distance needs a higher transmission power budget that can be achieved by increasing transmitter power, increasing receiver sensitivity, or increasing antenna gain. However, the design of communications systems on a flying platform is limited by the following constraints. The transmitter, receiver, and antenna must be compact, lightweight, and energy-efficient to save battery on the vehicle. Although the antenna does not directly influence the energy consumption from the battery, an increase in antenna gain usually requires an increase of the antenna dimension that causes higher weight and or reduces the aerodynamics. Therefore, the most efficient way to increase the link budget is by modifying the antenna on the GCS. This paper describes the analysis of antennas commonly used in GCSs for UAV communication links, namely the Yagi-Uda, bi-quad, and double bi-quad antennas. The antenna is designed to work at a frequency of 433.5 MHz following the transceiver device used. The antenna designs are numerically simulated then fabricated for evaluating their performance. The testing is done on the following issues, i.e. the antenna's basic parameters measurement, the ground-to-ground transmission test, and the ground to air transmission test. The test results show that the double bi-quad gives better performance than the other two other testing antennas.

Sistem pengawasan kesehatan jembatan adalah sistem pengumpulan data waktu-nyata yang terdiri atas komponen, respons, perubahan, dan proses konstruksi struktur jembatan. Tujuan sistem adalah untuk membantu menilai risiko keamanan struktural yang dapat merusak struktur jembatan dengan memanfaatkan Wireless Sensor Network (WSN) dalam pengambilan data. Sistem ini berfokus pada parameter struktur jembatan, tetapi tidak memperhatikan faktor kendaraan seperti berat kendaraan, pola kendaraan, dan jenis kendaraan yang melewati jembatan, yang juga dapat menjadi faktor penilaian kesehatan jembatan. Sistem lain, yaitu sistem kontrol lalu lintas, mengukur berat kendaraan menggunakan Weight in Motion (WIM). WIM dapat digunakan untuk memperoleh faktor-faktor kendaraan, terutama berat kendaraan, yang juga membantu dalam menilai kesehatan jembatan. Makalah ini mengusulkan integrasi kedua sistem untuk menciptakan sistem yang dapat mengukur kesehatan struktur jembatan serta memantau berat kendaraan. Melalui integrasi ini, dimungkinkan untuk mengelola waktu tidur dan bangun WSN yang membantu menghemat energi. Hasil eksperimen menunjukkan bahwa sistem dapat mengukur frekuensi alami mendekati nilai Finite Element Analysis (FEA) yang menunjukkan validitas sistem yang dikembangkan.
In Search of Authentic Peer Leaders: Finding, Nurturing, and Affirming

Published: June 2020

Luthans and Avolio (2003) have posited that we need methods to develop authentic leaders. One method is to form learning communities on college campuses. Within these communities, peer leaders influence the development of newly admitted peers. The question is: why do some students become peer leaders and others do not? We believe that the answer lies somewhere in their core values. By the time people enter college, they are predisposed to value certain end-states and modes of conduct. Therefore, it is important to determine these predispositions so that leadership development opportunities such as peer leadership can be made available to those who are ready for this type of development. However, at this point we do not know which core values make a difference. This gap in the knowledge is what led to this study. The findings identify the core values of both peer leaders and non-peer leaders. In most cases, these values are the same for both groups. However, the core value of a sense of accomplishment stands out as being significant in determining who will select this type of leadership development opportunity. The paper expands on how to find, nurture, and affirm these select students.
On ‘affective’ exceptions to sound change: an example from the Mojeño (Arawakan) kinship terminology system
Authors: De Carvalho Fernando O.
Published: June 2020

This paper discusses a postulated non-sound change-based development derived from the detection of an exception to a regular segmental correspondence and shows how this proposal receives independent support from internal etymologization within the domain of kinship terms. The affricate in the Proto-Mojeño etymon *-ótse ‘grandmother’ is hypothesized to derive from affective strengthening of a fricative *s, thus modifying the expected reflex *-óse via affective or phonosymbolic affrication. The fact that the predicted fricative reflex is found when *-óse ‘grandmother’ occurs as a member of a compound for ‘mother-in-law’, a meaning not subject to affective modification, offers striking support for the hypothesis. The paper illustrates how internally structured lexical fields — where relations of partial (internal) cognation exist — such as kinship terminology systems, provide an interesting testing ground for claims on affective, non-lautgesetzlich formal modifications, given the fact that etymologically related forms belong to domains (such as ‘blood relative’ versus ‘affine relative’) that differ in crucial ways as far as the affective dispositions and attitudes of speakers are concerned.

Antiretroviral therapy is believed not to be able to cure the disease; however, it can reduce mortality and morbidity. It also improves the quality of life of people with HIV. The success of the HIV/AIDS treatment is determined by adherence to antiretroviral therapy. ARV therapy is given in a long run and can be said as optimal if the compliance reaches more than 95%. The purpose of this study was to determine the relationship between certain factors and adherence to ARV therapy in people with HIV/AIDS. The design of this study was a descriptive correlational study with a cross-sectional approach. A total of 198 patients were recruited through a purposive sampling technique. The result of the study showed that there was no relation between adherence with age (p-value of 0.327), education (p-value of 0.859), and treatment (p-value of 0.74). From this study, it can be recommended that nurses need to improve their HIV counseling skills, especially about the benefits of adherence using a communicative media. Hospitals should also encourage more support to achieve better adherence in patients living with HIV/AIDS. Keyword: Adherence, HIV/AIDS, Antiretroviral Therapy
