Authors: Fernando Henky , Larasati Yuniar Galuh , Abdullah Irwan , Horakova Hana
Published: August 2024

This study aims to evaluate the attitudes of leaders shaped after being trapped in the practice of money politics by voters in general elections based on Islamic law. This context tends to be overlooked by previous studies discussing the issue of money politics in elections. In addition to responding to the shortcomings of previous studies, this study also focuses on evaluating the characteristics and implications of money politics in shaping leaders' attitudes post-election based on Islamic law. This study employs a qualitative descriptive approach based on Islamic law to explore the characteristics, factors, and implications of money politics on leaders' attitudes post-election. The findings of this study reveal three important contexts regarding the characteristics of money politics in elections in Indonesia that contradict Islamic law. First, the practice of money politics in elections often appears in the form of cash payments, digital money, and the provision of projects with political aims. Second, money politics practiced in elections is frequently influenced by structural, cultural, and infrastructural factors oriented towards transactional politics. Third, the money politics conducted by actors in the elections has shaped opportunistic, pragmatic, and even corrupt attitudes among leaders post-election.

Sustainable Development and Climate Resilience 2050: Evaluating Indonesia’s Environmental Legal Landscape
Authors: Situmeang Ampuan , Silviani Ninne Zahara
Published: August 2024

Climate change poses significant threats the continuity and resilience of the existing environment. Through the Climate Resilience 2050 agenda, all countries are expected to contribute to mitigating and limiting the effects of climate change, while reducing activities that have the potential to damage the Earth’s atmosphere. As a country endowed with rich environmental diversity, Indonesia must address these challenges and participate in global efforts to ensure a sustainable and livable environment for the future. This study uses normative legal research methods to analyze Indonesia’s legal readiness in the framework of making policies that can increase Climate Resilience 2050. Using a statutory and regulatory approach, this study finds that Indonesia has legal readiness in terms of basic norms to support policies that increase climate resilience, however, still has a normative void to support the implementation of climate resilience-oriented policies because the regulations regarding the application of basic environmental law norms are overly skewed towards facilitating business activities.
The influence of peripheral-bone-removal protocol on bone augmentation in dental implant surgery: 5-year clinical retrospective study
Authors: Alhamdani Faaiz , Hassan Ahmad Fliah , Al-Nuaimy Amaal
Published: August 2024

Background: Bone augmentation aims to provide sufficient bone volume around dental implants. Available bone augmentation methods include autogenous bone grafts, xenografts, and alloplastic materials. All have their advantages and disadvantages. However, autogenous bone graft remains the gold standard for bone augmentation. Autogenous bone grafts are usually taken from the patient’s oral donor sites such as the chin and mandibular ramus. However, there is a newly developed implant preparation protocol, known as the peripheral-bone-removal (PBR) technique, which can provide bone augmentation from the dental implant site. Purpose: This study aims to determine the need for bone substitute materials in the PBR technique in dental implant surgery. Methods: This study included 130 patients who were treated for dental implants. These patients were treated between 7.1.2018 and 3.2.2023. Six dental implant systems were used. Five of these systems (ImplantKa®, DeTech®, NeoBiotech®, Easy Implant®, and Dentaurum® Implant) used a conventional method (sequential drilling technique). The sixth (IBS®) system used the PBR protocol. Both descriptive and Chi-Square Test statistics were used for data analysis. Results: The included patients were treated with a total of 198 dental implants. Seventy patients were treated with the PBR protocol, while 60 patients were treated with the sequential drilling protocol. For the PBR protocol, only 2 cases required bone substitute material, whereas 11 cases treated with the sequential drilling protocol required augmentation materials. This difference between both drilling protocols has been statistically confirmed (P=0.008). Conclusion: The PBR technique appears to be less traumatic and more cost-effective for cases that require horizontal bone augmentation.
Effect of Ganoderma lucidum extract on tumor necrosis factor-alpha and prostaglandin E2 levels in periodontitis model Sprague Dawley rats
Authors: Andini Restian Febi , Novrial Dody , Widodo Haris Budi
Published: August 2024

Background: Periodontitis is a chronic multifactorial disease caused by microorganisms such as G-anaerobes in the periodontal tissues. It activates host defense cells and releases inflammatory mediators such as tumor necrosis factor-alpha (TNF-α) and prostaglandin E2 (PGE2). Ganoderma lucidum is a traditional medicinal mushroom with anti-inflammatory effects against various diseases. Biologically, different levels of its active constituents, such as triterpenoids and phenolic compounds, reduce inflammation with various pathways. Furthermore, the constituents inhibit toll-like receptor 4, MyD88 receptors, and the activities of nuclear factor-kappa B, which synthesize TNF-α and PGE2. Purpose: This study aimed to analyze the extent to which G. lucidum extract can reduce TNF-α and PGE2 levels in periodontitis model Sprague Dawley rats. Methods: Thirty Sprague Dawley rats were randomly divided into six groups of five rats. Periodontitis inflammation was induced by the injection of Porphyromonas gingivalis bacteria into intrasulcular gingival incisors in the lower jaw labial section. Grouping was as follows: Group K1 (healthy control); Group K2 (negative control); Group K3 (positive control with doxycycline dose 0.27 mg/kg BW); Group P1 (G. lucidum extract dose 5 mg/kg BW); Group P2 (G. lucidum extract dose 10 mg/kg BW); and Group P3 (G. lucidum extract dose 20 mg/kg BW). Samples were taken from rat gingival tissue and the levels of TNF-α and PGE2 were examined using the enzyme-linked immunosorbent assay method. Data analysis was performed using one-way analysis of variance (ANOVA) with a confidence level of 95% (p < 0.05). Results: The levels of TNF-α and PGE2 were the highest in the K2 group and the lowest in the K1 group. One-way ANOVA showed no significant difference in TNF-α and PGE2 levels between P3 and K1 group. Conclusion: G. lucidum extract can reduce TNF-α and PGE2 levels in Sprague Dawley rats with periodontitis.
Changes in denture teeth location in three different flasking techniques
Authors: Al-Ali Ahmed Asim , Mohammed Abdullah Jasim , Sheet Omar Abdul Mohsen
Published: August 2024

Background: Artificial tooth movement may compromise the occlusion of complete (or implant-supported complete) over-dentures. This movement can lead to traumatic occlusion that may need to be corrected because the planned harmonious occlusion is lost, mainly when anatomic artificial teeth are utilized. Purpose: The study was conducted to evaluate the effect of the combination of gypsum plaster and laboratory silicon on the artificial teeth movement during the flasking procedure using radiographic imaging of intra-flask changes. Methods: In the current study, 90 identical mandibular complete dentures were fabricated and divided into two groups according to the acrylic material used. Stainless-steel pieces (0.5×0.5) were placed in the (buccal and mesiobuccal) cusp tips of the first premolar and first molar on both sides. Each group was subdivided into three subgroups (n=15) representing different techniques of flasking. Radiographs were taken at three phases of the flasking procedure, before and after the second investment layer and after curing the acrylic. The anteroposterior and mediolateral factors were calculated, and the data were analyzed by the one-way analysis of variance (ANOVA) and Duncan’s post hoc tests at P˂0.05. Results: The anteroposterior factors of the groups had insignificant differences at all phases, and the mediolateral factors showed significant differences in the gypsum samples and total silicon samples. Conclusion: Anteroposterior movement of the artificial teeth was not changed due to bracing between the teeth, and a mixed silicon and plaster investing layer had the smallest teeth location changes during the packing and curing phases.

Authors: Kurnia Galuh Mega , Ersanti Arina Mufida
Published: August 2024

Background: Indonesia is in second place with the highest number of Tuberculosis (TB) cases in the world with a death rate reaching 144,000 cases per year. Smoking has become the second biggest risk factor for TB in Indonesia after poor environmental conditions and Indonesia ranks third with the highest number of smokers in the world. Objective: To analyze the relationship between cigarette expenditure and TB Case Notification Rate in 2021-2022. Method: The study design is an observational quantitative study using secondary data. Mapping was carried out using the QGIS application and spatial analysis was done using the GeoDa application's spatial regression. Results: in 2021 the majority of provinces in Indonesia are in the medium category for average per capita weekly cigarette expenditure and is in the low category for CNR TB. In 2022, most provinces in Indonesia were in the high category for average per capita per week cigarette expenditure and in the medium category for TB CNR. Papua Province needs to get more attention from the government because even though the average cigarette expenditure is low, the TB rate is high. DKI Jakarta Province needs to receive more attention because apart from its high TB rate, the average per capita cigarette expenditure is also high. There’s a relationship between cigarette expenditure and TB CNR in 2021 but not in 2022. Conclusion: There was an increasing trend in cigarette expenditure and TB CNR in Indonesia from 2021 to 2022 and a lack of consistency in the relationship between the two variables from 2021 to 2022.

Authors: Rohmah Nur , Rene Lamy Francois
Published: August 2024

Introduction: Smoking cessation is a critical step towards improving overall health and well-being, not only for individuals but also for their families. Although young fathers who smoke may have particular difficulties while trying to stop, they can conquer their addiction with the correct techniques and assistance. Objective: This study aims to investigate the strategies used by young Indonesian fathers to give up smoking after the birth of their children. Method: We gathered thirty young fathers who were smokers at the time for semi-structured, in-depth interviews. The process of coding data from grounded theory was utilized to interpret the acquired data, even though grounded theory was not the theoretical framework used in this investigation. Results: Some informants described their efforts to change their smoking behavior, including both external and internal efforts, for both individuals who intend to quit and those who continue to smoke. Numerous additional informants mentioned external efforts. The informants have different motivations for wanting to quit smoking. According to an analysis of the interviews, there are two main sources of motivation and/or intents for quitting: internal and external cues. Conclusion: The complex experiences that young fathers have when attempting to quit smoking are influenced by some factors, including the transition to parenting, specialized support programs, and the significance of family encouragement.
Artificial intelligence and liver transplantation: looking inside the Pandora’s box
Authors: Sepulveda Ailton , Pravisani Riccardo
Published: August 2024

Artificial intelligence (AI) is the discipline of computer science dedicated to processing a large amount of throughput data and is based on algorithms that can rationalize increasingly complex tasks and ultimately reproduce human intelligence. It has been speculated for clinical uses in liver transplantation (LT) for several years, but its application remains incipient worldwide. Therefore, the recent advancements of digital and robotic tools in daily medical practice make the modern environment propitious to its proper implementation. Nevertheless, it is noteworthy that this technology has significant limitations: (i) its unconditional dependence on a pre-established reliable and extensive database; (ii) the potential impact on independent medical decision-making; and (iii) a major economic and environmental burden. So, despite its seducing and flawless simplicity features, AI emerges as a new “Pandora’s box” that should be carefully understood and used under the light of ethical principles to improve clinical outcomes, promote medical and para-medical working conditions, and increase patient safety and access to medical care. The present work aims to review literature data supporting AI implementation on this basis.
On-surface synthesized magnetic nanoclusters of ferrocene derivatives
Authors: Sakurai Makoto
Published: August 2024

On-surface molecular self-assembly in solution can produce two-dimensional (2D) materials with unique surface nanostructures that have the potential to create new functionalities. The surface completely differs from the uniform flat surface of conventional 2D materials such as graphene, MoS2, and 2D van der Waals nanosheets. The recently developed on-surface chemical synthesis of amino-ferrocene (AFc) nanoclusters on a graphene oxide (GO) nanosheet is a technique based on molecular self-assembly. Here, this method is applied to other ferrocene derivatives whose ferrocene units are covalently bonded to an amino group and several other molecules. The structure of the on-surface synthesized nanoclusters is analyzed by high-resolution transmission electron microscopy and atomic force microscopy. The molecules in the nanoclusters are densely and regularly arranged, and the distance between the Fe ions of the constituent molecules is longer than that in the AFc nanoclusters. Band-through electron transfer occurs between the Fe ions and the GO nanosheet, generating unpaired 3d electrons whose magnetic state is in the high spin state (S = 5/2). The present study demonstrates the feasibility of the design and synthesis of functional molecular nanostructures with molecular precision by on-surface chemistry, leading to the fabrication of nanoscale building blocks with molecular precision and 2D platforms for next-generation molecular spintronic and neuromorphic devices.

Évolution des trajectoires paysagères et des connectivités hydrologiques dans deux bassins versants bocagers normands depuis deux siècles
Authors: GUILLEMOIS Mathilde , DELAHAYE Daniel , REULIER Romain
Published: August 2024

Depuis le milieu du vingtième siècle, les paysages bocagers du nord-ouest de la France subissent d’importantes mutations. Sous l’effet de la transformation foncière des exploitations agricoles, les parcellaires sont rationnalisés, remembrés et les haies sont fréquemment arasées. Ces mutations ont pour répercussion de multiplier les transferts hydro-sédimentaires et les connectivités hydrologiques entre les parcelles agricoles et le cours d’eau, impactant l’environnement (érosion des sols, pertes en sol, la pollution des milieux aquatiques). Ces conséquences déjà pressantes et pesantes pourraient devenir récurrentes dans un contexte de changement climatique. À l’heure où les enjeux liés à l’aménagement et à la préservation des territoires bocagers sont à repenser, il est intéressant de s’interroger sur la « vertueusité » des paysages passés au-regard des transferts hydro-sédimentaires. Cet article étudie l’évolution des connectivités hydrologiques depuis deux siècles sur différents bassins versants bocagers, afin d’offrir des perspectives quant à la gestion durable et future des territoires.
De l’invisibilité à la mise à l’agenda : l’émergence du problème des micropolluants dans l'eau, en France
Authors: LANA Enzo , LOUBET Audrey
Published: August 2024

Pourtant présentés comme un enjeu majeur des politiques publiques environnementales et sanitaires, les micropolluants et notamment les résidus de médicaments, continuent d’être qualifiés de « contaminants émergents » plus de cinquante ans après les premiers travaux de recherches démontrant leur impact sur les milieux, voire la santé humaine. Aujourd’hui, le problème est connu mais pas entièrement, pas par tous et pas de la même manière suivant les acteurs. Plusieurs aspects du problème sont par ailleurs encore inconnus, ou en débat. Il existe une réglementation européenne sur l’eau potable et les milieux aquatiques, transcrite par la suite en droit français, mais il n’existe pas de politiques publiques territorialisées et standardisées sur l’ensemble du territoire national. Cela revient donc à dire que le problème est en cours d’identification et de cadrage et, par conséquent, que le champ des possibles est (partiellement) ouvert. Il devient donc particulièrement intéressant de s’attacher à identifier les différents espaces et acteurs qui participent à ce travail de mise en lumière, pour comprendre les rationalités à l’œuvre, les liens entre les territoires, les recherches et les politiques publiques qui y sont menées, etc. Cet article propose de s’intéresser à la mise en problème des micropolluants, en effectuant notamment un tour d’horizon des programmes de recherches qui ont travaillé sur ces substances au cours des vingt dernières années afin d’observer les liens qui existent entre recherche scientifique, réglementation et mise à l’agenda politique.

Case:

A multicenter series of 3 patients with amyoplasia of the upper extremity were indicated for gracilis free functional muscle transfer (FFMT) to restore elbow flexion and found to have an absent gracilis. A final case is discussed detailing standardized evaluation with ultrasound to confirm gracilis before surgical intervention.

Conclusion:

In amyoplasia, the gracilis muscle may be absent or have fatty infiltration, making this donor muscle inadequate. Preoperative ultrasound to determine the presence of the gracilis is noninvasive and recommended in patients with amyoplasia of the upper extremity being considered for FFMT.
The State, the self, and the willingness to co-exist: teachers’ perceptions of the other in Israel

As a result of structured separation in everyday life, Israel’s Arab and Jewish youth rarely interact, which contributes to a deepening and mutual sense of distance, distrust, and racism. Teachers, as agents of social change, can lead educational processes to bridge the ideological distance between Arabs and Jews in Israel, and to create an environment of dialogue and acceptance. This study used a sample of 300 teachers (150 from the Jewish ethnic group and 150 from the Arab ethnic group) to explore their perceptions and attitudes. Findings revealed that, compared to their Jewish counterparts, Arab teachers perceive the state’s attitude toward them as more negative. We found that Arab teachers’ perception of citizen-state relations was higher than that of Jewish teachers; identity perception among Arab teachers was lower than Jewish teachers; and coexistence perception among Jewish teachers was higher than Arab teachers. These findings can be a base for intervention programs at national and local levels and encourage the adoption of multicultural strategies to integrate Israel’s Arab population as equal citizens through social and political motivations.
Influence of abstract thinking style on morality and sociability attributed to immigrants by people with more conservative ideologies

In current society, immigration is a reality that poses important challenges. Identifying factors that favor a more positive evaluation of immigrants could lead to new avenues of intervention to achieve more positive intergroup relationships and greater social well-being. Given that a more abstract thinking style promotes less focus on obstacles and difficulties, the aim of the present study was to examine the link between construal level and stereotype, focusing on people with a more conservative ideology, a population that tends to have a higher level of prejudice towards immigrants. We hypothesized that conservative people with a more abstract thinking style would report less negative stereotypes than those with a more concrete thinking style. In a sample of Spanish adults (N = 1,208, 60.1% women), we applied a questionnaire measuring thinking style, ideology, the degree to which immigrants are perceived as competitors, and the dimension of warmth (morality and sociability) of the stereotype content of that group. We found that more conservative people perceived, to a greater extent, immigrants as competitors and considered them less moral and sociable. However, the warmth (morality and sociability) attributed to immigrants was significantly higher for those conservative individuals who presented more abstract thinking style, with perceived competition as the mediating variable. As it is possible to induce a more abstract thinking style, the results of this study open a new avenue for intervention in promoting more positive attitudes toward immigrants, especially in more conservative people who tend to present more negative stereotypes towards this collective.
La humillación y su relación con la victimización por acoso: una revisión narrativa
Authors: Borrego-Ruiz Alejandro , Fernández Saulo
Published: August 2024

La humillación es un fenómeno vinculado a las dinámicas de acoso que origina interacciones perturbadoras y traumáticas para las víctimas. Por ello, la relación entre la humillación y el acoso representa un tema de investigación con repercusiones significativas para el ámbito del bienestar social. Los objetivos del presente trabajo son: revisar el concepto de humillación –y su naturaleza– de acuerdo con la literatura sobre este fenómeno; revisar las principales consecuencias derivadas de la experiencia emocional de humillación; y analizar la relación entre humillación y victimización por acoso. Para ello, se ha realizado una revisión narrativa basada en una selección de 78 artículos. La humillación se ha definido como una emoción autoconsciente que aparece cuando un individuo es injustamente degradado por otros. En una situación humillante, las personas que internalizan una devaluación del yo, y que valoran dicha situación como injusta, tienden a experimentar mayores niveles de humillación. La humillación se ha relacionado con conductas violentas comandadas por la represalia y con estados de indefensión que pueden culminar en suicidio. En el marco del acoso, la hostilidad aumenta la percepción de injusticia, mientras que el estatus social facilita la internalización de devaluación. Los testigos desempeñan un rol clave en la intensificación de la humillación, puesto que la víctima percibe la devaluación de manera más injusta, y la presencia de una audiencia facilita su internalización. Asimismo, responder activamente al acoso mitiga la experiencia emocional de humillación debido a una mayor percepción de control. La humillación resultante del acoso ejerce un impacto negativo en el bienestar social, por lo que el abordaje de este fenómeno requiere el estudio de los factores que permiten y perpetúan su contingencia.
Guest Editorial: Where Are Refracs Going, and Can We Make Them a Sure Thing?
Authors: Goodwin Alex , Nguyen Alex
Published: August 2024

Unlike new-drill wells, refrac wells don’t offer operators any flexibility on drilling location or where to land a lateral. These factors are already decided, which makes the keys to success twofold: picking the right refrac candidates and executing them with minimal operational risk.

With over 300 refracs under our belt, Vertice Oil Tools has had a front-row seat to the evolution of refrac technology and its significant impact for operators in the Lower 48 states.

Our journey with refracs, specifically mechanically isolated, or “ISO refracs” as we call them, started in 2018 in the Eagle Ford Shale and now includes over 100 patents and patents-pending, a quarter of which are specific to our refrac technology.

When we entered the market, operators were beginning to test refracs by cementing 4-in. casing inside of 5½-in. casing and then refracturing. Many of these first refrac pilots faced challenges. Oftentimes, the candidate selection might have been optimal, but the operational risk was high.

Refrac liner systems and other refrac tools have since matured and offer greater operational reliability along with lower costs.

At the same time, merger and acquisition activity in the tight-oil and gas industry has picked up as operators move to build up their inventory of new drilling locations. But one other driver that is emerging from the dealmaking is extracting more barrels from existing assets through refracturing.

At Vertice, we have identified what we believe to be almost 10,000 Tier 1 wells that are potentially prime candidates for refracturing. If properly executed, we estimate that refracs of these wells could generate more than $50 billion at a net present value at a 10% discount rate, or NPV-10.

At current commodity prices, the NPV-10 of a Eagle Ford or Bakken Shale refrac well is typically between $3.5 to $4.0 million with a payback between 1 to 2 years.

Given the fast cycle times of the shale sector, initial rates of return on refracs are also often north of 100%. With such returns, which often exceed those of new wells, refracs have increasingly become a key strategy for operators, and activity is expected to more than double this year.

With ISO refrac activity also expected to more than double this year, we believe the market is poised for continued growth.

While the Eagle Ford remains a hotspot, activity in the Bakken is catching up, and we believe other maturing basins will follow the trend as drilling inventory shrinks and refrac costs continue to drop.

We also see the industry moving towards more sophisticated refrac techniques, including protective refracs, where a refrac well is treated alongside newly stimulated wells on the same pad to achieve cost efficiencies and mitigate frac hits.
