Perspectives and Methodological Peculiarities in Developing the Form of Governance in the Republic of Armenia
Authors: Manasyan Anahit
Published: October 2023

The current article considers the issues concerning perspectives and methodological peculiarities of developing the model of governance in the Republic of Armenia. The history of developing the form of governance in the Republic of Armenia, advantages and disadvantages of different forms of governance, factors and circumstances, which should underlie the selection of the form of governance are studied in the article. The author concludes that, while speaking on the forms of governance, we are often guided by fictional perceptions, which should be overcome and cannot serve as the basis for reforms concerning the aforementioned issue. Moreover, in the result of processes of legal convergence, the forms of governance have borrowed from each other the mechanisms that are not originally typical of them, and from this aspect their rapprochement can frequently be noted. The author notes that the problems, solution of which is the main reason for continuous changes of the form of governance, will not be solved in conditions of new reforms implemented by the same logic. Hence, the axis of the problem of the further improvement of the model of governance in the Republic of Armenia should be transformed from the issue of making a choice between this or that form of governance, and the attention should primarily be focused on improving the mechanisms of separation and balance of powers, as well as forming and strengthening constitutional and political traditions and culture.
Subordinated Bonds and the Fulfilment of Their Obligations in the Event of State Aid
Authors: Kārkliņš Jānis , Zeņķis Pauls
Published: October 2023

A bond is a debt security, under which its issuer undertakes to repay to the bondholder the principal of the bond and the interest (the coupon) at a specified point in time, which is to be considered as the redemption of bonds. Bonds have several types: bonds issued by the public sector, bonds issued by capital companies, publicly available bonds, private bonds, convertible bonds, contingent convertible (CoCo) bonds, exchangeable bonds, exchange bonds, callable bonds, subordinated bonds, etc. In economic circulation, subordinated bonds are widespread securities. The subordinated obligation in the bond distinguishes the subordinated bond from other bonds. At the same time, the underlying relationship entails significant risks for the fulfilment of the obligations arising from the bond, which is outweighed by the higher profitability of such bonds. However, there are cases where the obligations arising from subordinated bonds are never met. Such cases may be based not only on the insolvency of the issuer of the subordinated bonds but also on the existence of State aid received by the issuer. In view of the recent financial difficulties of several banks, the likelihood of an issuer that has received State aid being able to meet its obligations under subordinated bonds becomes a particularly acute matter.
Consolidation of the Principle of Democratic Elections in the Law of the Latvian People
Authors: Lazdiņš Jānis
Published: October 2023

The article provides an analysis of the gradual consolidation of the principle of democratic elections in the election law of the Latvian people during the period from the abolition of serfdom in the Baltic Governorates of the Russian Empire at the beginning of the 19th century until the adoption of the Satversme [Constitution] of the Republic of Latvia on 15 February 1922. Abolition of serfdom was chosen as a point of reference for the publication, because “emancipation” gave liberty to the majority of Latvians as persons belonging to the peasant class. Until proclamation of the Republic of Latvia (1918), Latvians gained election experience in electing the councils of civil parishes, cities and the State Duma of the Russian Empire. None of the elections held in the Russian Empire can be considered to be democratic, since the principle of voters’ equality was not complied with. Demand for democratic elections as denial of inequality consolidated among the Latvian people by the end of the 19th century. It is proven by the projects of Latvia’s autonomy, elaborated even before the democratic February Revolution in the Russian Empire (1917). Following the proclamation of the Republic of Latvia, the legislator only enshrined (documented) in legal acts the will of the Latvian people to elect state and local government officials democratically.
Władysław Tarnawski and the Critical Reactions of the National Democratic Party in Lviv to the Changes of the March Constitution (1926–1935)
Authors: Pudłocki Tomasz
Published: October 2023

The article considers the problem of reaction of the greatest Polish opposition party to the post-1926 “Sanation”, namely, the right-wing National Democrat attitudes to the ideas of changes of the Polish Constitution of 1921. The author focuses on the King John Casimir University in Lviv milieu (mostly professors, but also graduates and those allied with these circles – lawyers and journalists). Among many advocates protesting against ruling party’s reforms of the Polish law was Władysław Tarnawski – the professor of English Philology at the University and one of the leaders of Lviv’s right wing. An analysis of the discourse on Polish law carried out by opposition parties against the post-May government allows to grasp the richness of Polish parliamentary life in the authoritarian period. Despite the numerous studies in Polish historiography dealing with the milieu of the National Democrats between 1918 and 1939, the Lviv branch of this party has been understudied.
The Protection of Fundamental Rights by the Constitutional Court in the Republic of Latvia. Perspectives, Opportunities and Limits of an Introduction of the Model in Italy
Authors: Di Capua Viviana
Published: October 2023

The contribution aims to analyse the constitutional complaint in the Republic of Latvia, a particular type of appeal to the Constitutional Court that can be filed by an individual directly, without any intermediation, if a legal norm that conflicts with a hierarchically superordinate source has caused a violation of one of his or her fundamental rights provided for in the Constitution the Republic of Latvia of 15 February 1992 (Satversme). The objective will be to explore, also through the examination of constitutional jurisprudence, the adequacy of this technique of protecting fundamental rights in the Republic of Latvia, the possible development of the legal system through the referral to the Latvian Constitutional Court of issues that should have been dealt with by the legislature, and its exportability in the Italian legal system. With regard to this last profile, we will proceed to examine the obstacles to the introduction of some form of direct access to the Constitutional Court, represented not already by Article 134 of the Constitution (which, notoriously, provides for the jurisdiction of the constitutional court “over disputes relating to the constitutional legitimacy of laws and acts, having the force of law, of the State and the Regions”), but by Constitutional Law no. 1 of 1948 and Law No. 87 of 1953, which structure the control of constitutionality exclusively on incidental access (“in the course of a judgment”) and by the model of protection of fundamental rights outlined by the Constitution, in which the function of protection is attributed to the ordinary judge and, in cases of exclusive jurisdiction, to the administrative judge. Finally, special attention will be paid to the constitutional jurisprudence on election laws, which, according to some, would have legitimized the introduction in the national system of a direct appeal “disguised” as an incidental appeal.
Disparitas Putusan Mahkamah Agung dan Pengadilan Agama dalam Penerapan Fasakh terhadap Perceraian atas Dasar Murtad
Authors: Nasution Muhammad Idris
Published: October 2023

Mahkamah Agung dalam dua putusannya secara konsisten membatalkan putusan Pengadilan Tinggi Agama yang telah memutus fasakh terhadap perkara cerai talak karena telah terbukti terjadinya peralihan agama salah satu pasangan suami istri. Mahkamah Agung menilai pemberian izin talak raj’i lebih tepat dengan alasan sesuai posita dan petitum permohonan. Penulis menemukan sebelas putusan Pengadilan Agama pasca dua putusan Mahkamah Agung tersebut tetap menjatuhkan fasakh jika telah terbukti peralihan agama salah seorang pasangan suami istri meskipun tidak dijadikan alasan perceraian dan tidak diminta oleh pihak dalam petitumnya. Dalam artikel ini, penulis akan mengkaji pertimbangan-pertimbangan hukum sebelas putusan Pengadilan Agama tersebut dengan menggunakan metode eksplanatif dan disajikan secara kualitatif. Hasil kajian penulis menunjukkan pertimbangan hakim dipengaruhi persepsi hakim terhadap penerapan asas ultra petita dengan asas ex aequo et bono, persepsi hakim terhadap penerapan mazhab-mazhab fikih dalam putusan, serta persepsi hakim atas kemandirian hakim dan kepatuhan yursiprudensi.
Tujuan Hukum Islam untuk Kemaslahatan Manusia: Penerapan Kaidah Fiqhiyah dalam Bidang Ekonomi dan Hukum Keluarga
Authors: Nurdin Abidin , Usman Bustami , Samad Fauzan , Mukhtar Makmunzir
Published: October 2023

Kajian ini membahas tentang tujuan hukum Islam adalah untuk kemaslahatan manusia khususnya penerapan kaidah fiqhiyah dalam bidang ekonomi dan hukum keluarga. Metodologi Hukum Islam atau ushul fiqh dikenal qawaid fiqhiyah sebagai alat untuk untuk mempermudah proses istinbath dan metode ijtihad dalam menentukan suatu hukum. Kajian ini merupakan studi hukum Islam secara teoritis atau normatif, dengan menggunakan teori hukum Islam. Penelitian ini menyimpulkan bahwa tujuan hukum Islam yang paling utama adalah untuk kemaslahatan manusia di dunia dan akhirat yang dikenal dengan istilah maqashid al-syariah. Kemudian kaidah fiqhiyah dalam bidang ekonomi (mudharabah dan musyarakah) digunakan misalnya; “Pada dasarnya semua muamalah boleh dilakukan, terkecuali ada dalil yang mengharamkannya.” Kaidah ini bermakna kebolehan dalam muamalah itu selama belum ada dalil yang jelas melarang dan mengharamkannya, itulah prinsip dasar dalam menentukan hukum-hukum yang berkenaan dengan muamalah. Qawaid fiqhiyah dalam hubungannya dengan hukum keluarga Islam dikenal ada kaidah al-adat al-muhakkamah (adat dapat dijadikan sebagai hukum) diimplementasikan dalam hal pembagian harta bersama. Demikian juga kaidah fiqhiyah yang digunakan dalam putusan hakim Pengadilan Agama pada kasus perceraian antara suami dan isteri yang tidak mungkin lagi mempertahankan perkawinannya. Hal ini berpegang pada kaidah fiqhiyah:  ”Apabila ada dua hal yang sama-sama mengandung mudlarat, maka harus dipilih satu diantaranya yang lebih kecil mudlaratnya.” Kaidah-kaidah ini menunjukkan keluasan dan keluwesan hukum Islam yang akan mewujudkan kemaslahatan manusia sebagai tujuan utama hukum Islam
The Impact of The Minimum Age Limit Regulation for Continuing Child Marriage After the Birth of Law Number 16 Of 2019 on The Child's Future

Published: October 2023

Regulations will always be present as a compass so that humans as social creatures do not run away from the right path. This study shows from a direct perspective from society's perspective the impact of the Minimum Age Regulations for Entering into Child Marriages After the Birth of Law Number 16 of 2019 on the future of children which is studied by looking at how much the implementation of this law is in line with the current rules and habits of society. By using a descriptive research method, the author aims to be able to obtain results from research carried out using a Sociological Juridical approach, namely assessing the work of law in society because the functioning of law in society can be seen from the level of legal effectiveness. From the results of research on the impact of regulations on the minimum age limit for entering into a child marriage after the birth of Law Number 16 of 2019 on the future of children, it is clear that the law or a rule must always be updated so that it cannot be broken by developments in society's behavior as a legal subject
The Cancellation of The Weddings for Pre-Marriage Pregnancy Women: An Evaluation of Decision 24/Pdt.G/2020/Ms. Ban
Authors: Zainuddin Muslim
Published: October 2023

Marriage annulment is not limited to cases of polygamy without permission, remarriage during the 'iddah period, marriages without a guardian, or coerced marriages could also be annulled. In Decision Number 24/Pdt.G/2020/Ms. Ban, the court annulled the marriage of a minor who were pregnant pre-marriage. This is a normative legal research focusing on statutory regulations and legal concepts to address this issue. Legal sources used include primary, secondary, and tertiary sources, and a qualitative approach was used to analyze the data. The findings of this study indicate that the procedure for requesting an annulment of a marriage involves submitting a request to the Syar'iyah Court along with supporting evidence in the form of documents and the testimony of witnesses who witnessed the marriage event. The panel of judges declared the marriage between the petitioner and the respondent null and void at the conclusion of the trial, rendering the marriage certificate null and void. In addition, the judicial tribunal requested that the Religious Affairs Office (KUA) remove the marriage record from the register book. The reason for annulling a marriage is that it was performed by the sibling of the applicant’s father. However, the applicant’s father did not have the authority to be a marriage guardian because the applicant was an illegitimate child; therefore, he had only a relationship with his mother and her family. Legally, the annulment of the marriage is justified because the marriage between the petitioner and the respondent does not comply with the statutory requirements and conditions. One of the unfulfilled pillars is the lack of a guardian with the authority to solemnize the marriage. Supposedly, the guardian of children conceived outside of marriage should be a judge.

Published: October 2023

Polyporus species is a valuable species of the Polyporaceae family with defined bioactive properties among medicinal mushrooms. This study was undertaken to investigate the antioxidant, anticholinesterase and antidiabetic activities of Polyporus squamosus (Huds.) Fr. with characterization of phenolic profile by HPLC-DAD. Fumaric acid (190.07±0.08 µg/g), catechin hydrate (46.96±0.02 µg/g), ferulic acid (21.98±0.03 µg/g), trans-cinnamic acid (16.66±0.02 µg/g), and protocatechuic acid (13.29±0.06 µg/g) were detected as the most abundant compounds in P. squamosus by HPLC-DAD. P. squamosus methanol extract exhibited higher antioxidant activity than the hexane extract in β-carotene linoleic acid (IC50: 73.75±0.28 µg/mL), DPPH• scavenging (7.56±0.00% inhibition at 400 µg/mL), ABTS•+ scavenging (IC50: 154.30±0.55 µg/mL), and metal chelating (35.61±1.20% inhibition at 400 µg/mL) assays. P. squamosus hexane extract was determined as the stronger inhibitor than the methanol extract against all enzymes with inhibition values of 39.48±0.45% on AChE at 200 µg/mL, 28.02±1.34% on BChE at 200 µg/mL, 96.70±0.80% on α-amylase at 1000 µg/mL, and 39.93±0.52% on α-glucosidase at 500 µg/mL. The present study highlighted the importance of P. squamosus as a promising source of valuable therapeutic compounds that could be considered as an alternatives to synthetic drugs.

A dynamic model is proposed for photopolymerization of 1,6-hexane-diol
diacrylate (HDDA) with bifunctional initiator bis-acylphosphine oxide
(BAPO) in the presence of oxygen. This partial-differential-equation
(PDE) model predicts time- and spatially-varying vinyl-group conversion
as well as concentrations of monomer, initiator, oxygen, and seven types
of radicals. Experiments to obtain diffusivities of oxygen, BAPO and
HDDA are reported. Oxygen-related parameters are estimated using
real-time Fourier-transform infrared (FTIR) conversion data. FTIR
experiments were conducted using a range of film thicknesses (8-17 μm),
BAPO levels (1-4 wt%) and light intensities (200-6000 W/m^2). The
model predicts qualitative trends. Conversion predictions for runs with
high intensities (≥5000 W/m^2) and high BAPO (4 wt%) are accurate
with a root-mean-squared error (RMSE) of 0.04. Larger RMSE (0.13) for
runs with lower intensities and BAPO indicates that improved parameter
estimates are required. Parameter estimates will be updated using in
future using a model that accounts for shrinkage during polymerization.
Cost Estimation Trends for Major Defense Acquisition Programs
Authors: Jones Sammantha , White Edward , Ritschel Jonathan , Valentine Shawn
Published: October 2023

The authors use both descriptive and inferential techniques to investigate average and standard deviation trends in cost estimates for major defense acquisition programs (MDAPs) grouped into decades from the 1970s to 2010s. For total program-cost-growth factors (CGFs), the 2010s exhibited lower CGFs compared to the 1990s. For the program-acquisition-unit cost (PAUC) CGFs, the 2010s appear lower than the 1990s and borderline lower than the 1970s. A statistically significant decreasing trend in the standard deviations of total program CGFs throughout the decades was identified. This lowering variability trend also appeared for PAUC CGFs from the 1980s onward. This finding appears to be the first documented case known to us. This decreasing variability of cost estimates suggests to us that cost estimating and/or the process behind it might be improving over time.
Cost Overrun Optimism: Fact of Fiction?
Authors: Christensen David
Published: October 2023

Program managers are advocates by necessity. When taken to the extreme, program advocacy can result in the suppression of adverse information about the status of a program. Such was the case in the Navy’s A-12 program. In “A-12 Administrative Inquiry,” Beach (1990) speculates that such “abiding cultural problems” were not unique to the Navy. To test that assertion, this article examines cost overrun data on 64 completed acquisition contracts extracted from the Defense Acquisition Executive Summary database. Cost overruns at various contract completion points are compared with projected final cost overruns estimated by contractor and government personnel. The comparison shows that the overruns projected by the contractor and government were excessively optimistic throughout the lives of the contracts examined. These results were found insensitive to contract type (cost, price), contract phase (development, production), the type of weapon system (air, ground, sea), and the military service (Air Force, Army, Navy) that managed the contract.
Review of polymer-matrix composites welded to aluminium alloys

Published: October 2023

This review covers previous work by different scholars on welding
polymer-matrix composites to aluminium alloys between 2015 and 2021. The
highest tensile shear stress measured for the joint between polymer-matrix
composite and aluminium (AA7075) alloy was 59.9 MPa. Welding using
top-thermic friction stir was the method that produced the desired outcome.
Additionally, the aluminium (AA2024) alloy and fibre-reinforced polymer
composite were joined using an ultrasonic metal welding procedure, which
produced a weld with a high tensile shear strength of roughly 58 MPa. The
friction-aided joining of carbon fibre-reinforced polyphenylene sulphide
composites and aluminium (AA7075) alloy has been studied by researchers. A
laser treatment was applied to the aluminium surface to enhance the
interlocking between the two materials being combined. This development was
reported to cause inadequate bonding between the polymer-matrix composite
and the metal. Despite this, the joints demonstrated significant
load-bearing capacities of up to 10.7 kN.
Effect of pretreatment with pentanol for dyeing wool fibers at low temperature
Authors: Nikodijevic Milena , Djordjevic Dragan
Published: October 2023

This paper describes the influence of pre-treatment with pentanol for the
dyeing of wool fibers at low temperatures. Wool fiber is expensive to
produce and process; accordingly, it must be economically viable and meet
consumer demands. Acid dyes are the most important class of commercial dyes
and account for more than half of the dyes in the industry. Isomers of
pentanol and alcohols with a longer carbon chain have higher reactivity at
low temperatures and lower impact resistance. In the experimental part, the
100% wool fiber was treated in pentanol at a temperature of 20?C for 30
minutes. After pretreatment, samples were dried and relaxed at room
temperature for 24 hours. This is followed by dyeing the treated fibers with
Supramin blau acid dye. The used dye concentrations were 100, 200, 300, 400,
and 500 mg/dm3. The time of dyeing was 5, 10, 20, 30, 40, 50, and 60
minutes. Pretreated wool fibers with pentanol give good results at low
temperatures i.e. 40?C. A constant increase in the degree of dye exhaustion
on the pretreated wool fiber was observed during the increase in the
initial concentration of the dye. A longer dyeing time for pretreated wool
results in a higher degree of exhaustion. A pseudo-first-order adsorption
model can be used to describe the adsorption process because there is very
little deviation around the ideal curve and functional straight lines cover
most points.
Dyeing of the woolen knitwear with acid dye

Published: October 2023

The process of woolen knitwear dyeing using acid dye is investigated in this
paper. Wool, as a natural protein fiber, is quite costly to produce and
process, and thus it is crucial to ensure its economic viability and meet
consumer demands. Acid dyes are a popular choice for woolen knitwear dyeing
because of their strong coloring properties and ability to bind to the
protein fibers in wool. They are usually strongly dyed compounds whose
colouring depends on the molecular structure. A woolen knitwear made of 100%
extra fine merino wool was used. In this specific study, was used a brand of
acid dye called Supramin Blau GW and tested different concentrations and
dyeing times to see how they affected the final color of the wool fibers.
The dye concentrations were 100, 200, 300, 400, and 500 mg/l. The dyeing
time were 5, 10, 15, 25, 35 and 45 minutes. The aqueous dye solution had an
electrolyte concentration of 2 g/l of sodium acetate and acetic acid for a
pH of 5, while the dyeing temperature was 98?C. The results showed that
initial dye concentration and dyeing time increased, resulting in a
corresponding increase in the degree of dye exaustion on the wool fibers. A
longer dyeing time resulted in a higher degree of dye exhaustion. The
Freundlich's and Langmuir's models were used to describe the adsorption
process, which gives the relationship between the amount of dye adsorbed on
the woolen knitwear and the concentration of dye in the solution.
Freundlich's model was better that Langmuir's model for describing the
adsorption process because there was very little scatter around the ideal
curve and functional straight lines covered most points well. Overall, this
study highlights the importance of understanding the factors that influence
the dyeing process of woolen knitwear with acid dyes, as it can help ensure
that the final product is economically sustainability and meets consumer
demands.
Kinetic and isotherm evaluation of o-cresol adsorption on activated carbon procured from olive pomace
Authors: Choukchou Braham Salima , Taleb Zoubida , Djeziri Soumia , Djellouli Hadja
Published: October 2023

This article aims to apply an activated carbon on the adsorption of o-cresol
in an aqueous medium. Our work presents a double environmental aspect: On
one hand, a valorization of under-natural products, which is the olive
pomace and on the other hand, the study of the adsorbent efficiency of the
activated carbon resulting from these cores. Activated carbon is prepared
with chemical activation of olive pomace using H3PO4. The characterization
of this porous material has shown a specific surface area equal to 651 m2/g
with the presence of mesopores. Various parameters influencing the
adsorption were optimized, mainly the effect of the contact time, initial
concentration of o-cresol and pH of the solution were studied. The
experimental results show that the sorption equilibrium is reached within
60 min with an adsorption yields of 83.66%. Indeed, the experimental
adsorbed quantity of adsorbent is 3.82 mg/g with o-cresol concentration of
50 mg/L, T = 30?C and pH 2.6 for the better adsorption. The adsorption
process was also studied by examining Langmuir, Freundlich, Temkin isotherm,
and Dubinin-Radushkevich (D-R) isotherm models. The results revealed that
the adsorption system followed the pseudo-second order model and the
Freundlich model. Several thermodynamic factors, namely, the standard free
energy (?Gads), enthalpy (?Hads), and entropy (?Sads) changes, were also
calculated. The results demonstrated that the adsorption process is a
physical and endothermic. The obtained results are interesting, and
applications on other pollutants, in wastewater are in progress.
Evaluation of the efficiency of liquid degassing technology based on the principle of hydrodynamic cavitation
Authors: Nedbailo Anna , Ivanitsky Georgy , Tselen Bogdan , Obodovych Oleksandr , Radchenko Natalia
Published: October 2023

The article presents data on the evaluation of the effectiveness of liquid
degassing in the conditions of hydrodynamic cavitation, which is
implemented in a Venturi tube. Based on the conducted experimental studies
and the obtained data on the change in pH of the liquid, a change in the
carbonic acid-dissolved gas balance was observed. In the terms of the single
bubble dynamics model, the potential different sizes growth of gas
microbubbles of under pressure relief conditions for two treatment modes is
determined. It was found that increasing the efficiency of degassing causes
the pressure in the cavitator to decrease to the maximum possible negative
pressure. This allows the growth of the smallest bubbles to be activated in
the degasser equipment. It is shown that the theoretical assessment of the
potential effectiveness of cavitation degassing is somewhat overestimated.
This is explained by the difference in calculated pressure values and
actually created pressures in the degassing equipment. Correlation of
theoretical calculations of cavitation efficiency based on experimental
data showed that in the proposed treatment modes it is possible to activate
bubbles from 1.5 to 3.0 ?m, which also ensures a high degree of degassing.

Authors: Wang Yipeng , Wang Peiqi , Ye Shiyang , Shi Yu , He Yiruo , Han Xianglong , Bai Ding , Xue Chaoran
Published: October 2023

Objectives

To determine the optimal settings for reconstructing the buccal surfaces of different tooth types using the virtual bracket removal (VBR) technique.

Materials and Methods

Ten postbonded digital dentitions (with their original prebonded dentitions) were enrolled. The VBR protocol was carried out under five settings from three commonly used computer-aided design (CAD) systems: OrthoAnalyzer (O); Meshmixer (M); and curvature (G2), tangent (G1), and flat (G0) from Geomagic Studio. The root mean squares (RMSs) between the reconstructed and prebonded dentitions were calculated for each tooth and compared with the clinically acceptable limit (CAL) of 0.10 mm.

Results

The overall prevalences of RMSs below the CAL were 66.80%, 70.08%, 62.30%, 94.83%, and 56.15% under O, M, G2, G1, and G0, respectively. For the upper dentition, the mean RMSs were significantly lower than the CAL for all tooth types under G1 and upper incisors and canines under M and G2. For the lower dentition, the mean RMSs were significantly lower than the CAL for all tooth types under G1 and lower incisors and canines under M, G2, and G0 (all P < .05). Additionally, the mean RMSs of all teeth under G1 were significantly lower than those under the other settings (all P < .001).

Conclusions

The optimal settings varied among different tooth types. G1 performed best for most tooth types compared to the other four settings.

Authors: Hocking Samantha L. , Markovic Tania P. , Lee Crystal M.Y. , Picone Tegan J. , Gudorf Kate E. , Colagiuri Stephen
Published: October 2023

OBJECTIVE

We aimed to assess whether remission of type 2 diabetes (T2D) could be achieved with a low-energy total diet replacement (TDR) in an Australian primary care setting.

RESEARCH DESIGN AND METHODS

Individuals aged 20–65 years with T2D duration up to 6 years, BMI >27.0 kg/m2, and not treated with insulin were prescribed a 13-week low-energy TDR (Optifast; Nestlé Health Science) followed by 8-week structured food reintroduction and 31-week supported weight maintenance. The primary outcome was T2D remission at 12 months.

RESULTS

A total of 155 participants comprised the intention-to-treat population. At 12 months, T2D remission was achieved in 86 (56%) participants, with a mean adjusted weight loss of 8.1% (95% CI 7.2–9.1). Two serious adverse events requiring hospitalization related to the study intervention were reported.

CONCLUSIONS

At 12 months T2D remission was achieved for one in two Australian adults in a primary care setting.

We used 2008–2020 data from the cross-sectional Medical Expenditures Panel Survey to calculate the proportion of U.S. adults ≥18 years of age with diagnosed diabetes who reported receiving preventive care services, overall and by subpopulation (n = 25,616). We used joinpoint regression to identify trends during 2008–2019. The six services completed in the past year included at least one dental examination, dilated-eye examination, foot examination, and cholesterol test; at least two A1C tests, and an influenza vaccine.

RESULTS

From 2008 to 2020, proportions of U.S. adults with diabetes receiving any individual preventive care service ranged from 32.6% to 89.9%. From 2008 to 2019, overall trends in preventive services among these adults were flat except for an increase in influenza vaccination (average annual percent change: 2.6% [95% CI 1.1%, 4.2%]). Trend analysis of subgroups was heterogeneous: influenza vaccination and A1C testing showed improvements among several subgroups, whereas cholesterol testing (patients aged 45–64 years; less than a high school education; Medicaid insurance) and dental visits (uninsured) declined. In 2020, 8.2% (95% CI 4.5%, 11.9%) of those with diabetes received none of the recommended preventive care services.

CONCLUSIONS

Other than influenza vaccination, we observed no improvement in preventive care service use among U.S. adults with diabetes. These data highlight services and specific subgroups that could be targeted to improve preventive care among adults with diabetes.

Comics (sequential art) provide a frame to tell and understand stories and are suited to exploring complex, place-based, and time dependent ‘wicked’ issues.Social interaction and artistic co-creation offer direct health/wellbeing benefits. Climate change is the ‘single biggest health threat facing humanity’(WHO, 2021) and older people are particularly vulnerable today, younger people in the future. We want to give voice to older and younger generations as agents of change, understand experiences, traditions of sustainable behaviours, and offer visions for the future. Intergenerational work can generate solidarity, debate, and knowledge sharing.

Published: October 2023

O trabalho faz parte de um projeto de Educação Ambiental realizado em uma escola localizada em um município do estado de São Paulo, com alunos do Ensino Fundamental, e buscou envolver a comunidade escolar nas questões ambientais, principalmente na problemática que envolve a inadequada disposição de resíduos sólidos apontando alternativas que possibilitem o gerenciamento deles. Dentre as atividades realizadas, destaca-se a montagem de uma composteira, apresentada aos membros da escola (funcionários e alunos) como alternativa para o tratamento dos resíduos orgânicos gerados na escola, obtendo-se como resultado um composto, rico em matéria orgânica, sendo este depositado em um espaço que futuramente transformar-se-á em uma horta. Experiências laboratoriais, como a produção de um biodigestor e a síntese do biodiesel, contribuíram para a confirmação de que alguns resíduos sólidos descartados no ambiente domiciliar podem ser utilizados como fontes de energia limpa e renovável; outros resíduos serviram como matéria-prima para a produção de sabão em barra e papel reciclado, sendo que para a confecção do sabão utilizou-se óleo de cozinha usado e a produção do papel reciclado, contou com os papéis descartados e não inutilizados pelos membros da escola. Cabe ressaltar que parte destes papéis, serviram como material reutilizado, fundamental para a montagem de bloquinhos de anotações. A prática desenvolvida na execução das atividades foi utilizada como ferramenta estratégica e eficaz na difusão da Educação Ambiental na escola, conforme demonstraram os resultados obtidos.

Learning science using Group Discovery Learning (GDL) will help the learning process because this learning can train students to learn actively and independently in a learning process. The results of interviews with subject teachers showed that there are no modules, only LKS and a limited number of Package Books. Many students learning outcomes have not reached the KKM standard value. From the results of the interviews, researchers will develop a GDL-based module as a learning resource to improve students' cognitive learning outcomes. This study aims to produce learning tools developed, namely GDL-based modules, to enhance students' cognitive values by using modules in class VII MTs Riyadlatul Ulum. This type of research is the development of a Science Learning Module based on Group Discovery Learning using the 4D development model, Define, Design, Develop and Disseminate, suggested by Thiagarajan and Sammel. The analysis results from the design expert test were 95%, the material expert test was 85%, and the student response test was 89%. The results of the discussion regarding the development of the module can be concluded that before the development of the completeness module, students were only 33%. Still, after using the module, the first meeting increased by 70% and to 87% at the second meeting. So the module development is feasible to be used and used as a science learning resource and can improve students' cognitive learning outcomes.

Published: October 2023

The Environmental Monitoring Plan (EMP) and the Monitoring and Control Plan (MCP) are key documents required respectively in Environmental Impact Assessment (EIA) procedures and in the Integrated Environmental Authorization (IEA) for activities subjected to this procedure. Both documents aim at preventing impacts on the environment and human health and/or quickly taking actions if anomalous levels of pollutants are found in the environment. Trentino is an Italian region located in the Alps characterized by high population density in its valleys, complex terrain and, thus, a low level of dispersion of the atmospheric pollutants. The research carried out in Trentino in the last two decades has allowed identifying innovative monitoring approaches to point out issues that conventional methodologies could not detect. The present paper provides the key elements of an EMP that must be included in the EIA of a waste gasification plant. The paper proposes unconventional monitoring campaigns to guarantee a more efficient control of the areas influenced by the plant before, during and after its construction. The paper also discusses key aspects of an MCP for plants that are subjected to IEA. The final aim is to make this paper a reference document to 1) evaluate new projects of waste combustion plants, 2) suggest alternative monitoring methodologies to investigate the role of specific pollutants in peculiar contexts, and 3) prescribe a specific surveillance plan in the case of a plant that is subjected to IEA. Considerations on differences with conventional plants were also included.
