Authors: - H.A. Dimani Tharuka Hapuarachchi
Published: April 2024

This research investigates the factors influencing fast-food consumption among university students in Sri Lanka, considering the economic challenges and prevalence of this dietary trend. The study draws on established definitions of fast food, emphasizing the interchangeability of the terms "fast food" and "junk food," with a crucial distinction that not all fast foods are inherently unhealthy. Notably, the research explores the nutritional implications of fast food consumption, highlighting the findings and addressing the changing eating patterns identified by previous studies. The study is driven by the evolving trend among Sri Lankan university students, mainly during the economic crisis, where the younger population, determined by economic constraints, turns to inexpensive fast food options available within university canteens. The research aims to observe and analyze the factors influencing this consumption pattern. The materials and methods involve demographic analysis through an online questionnaire, encompassing both closed-ended and open-ended questions. The survey targets 265 undergraduates, revealing a significant preference for fast food, particularly during lunchtime. The study employs factor analysis techniques, with a focus on the principal components factor (PCF), to interpret the motivations behind students' fast food choices. The analysis identifies four key factors influencing fast food preferences: the relation between product quality and pricing, ease of convenience, offerings and customer service, and time constraints and limitations. The conclusion synthesizes the findings, emphasizing the nuanced understanding gained through factor analysis regarding the complex motivations behind university students' fast food consumption. The research contributes valuable insights for stakeholders in academia, the fast-food industry, and policymakers. Recommendations are personalized to the Sri Lankan context, proposing strategies such as local nutritional awareness campaigns, promoting local fast-food alternatives, incorporating cultural sensitivity in marketing, establishing university canteen guidelines, fostering community engagement, and supporting sustainable agriculture initiatives.

Published: April 2024

Epilepsy is a neurological disorder characterized by recurrent seizures, affecting millions of people worldwide. Despite advancements in therapeutic interventions, there remains a need for novel and effective treatments with fewer side effects. This study aimed to evaluate the anti-epileptic potential of Leucas cephalotes leaves through experimental models. The leaves of Leucas cephalotes were collected, dried, and subjected to extraction using suitable solvents. The obtained extract was then evaluated for acute toxicity using standard guidelines. Subsequently, anti-epileptic activity was assessed using chemically induced seizure models in rodents. Behavioral observations, seizure latency, duration, and severity were recorded to determine the extract's efficacy. Preliminary phytochemical analysis of the extract revealed the presence of alkaloids, flavonoids, terpenoids, and phenolic compounds, which are known for their neurological effects. Acute toxicity testing indicated the safety of the extract at tested doses. In seizure models, the extract demonstrated a significant increase in seizure latency, reduction in seizure duration, and alleviation of seizure severity compared to control groups. These findings suggest that the leaves of Leucas cephalotes possess anti-epileptic properties, possibly attributed to the presence of bioactive compounds. Further studies are warranted to elucidate the underlying mechanisms and optimize dosage regimens for clinical application. Leucas cephalotes could emerge as a promising natural source for developing anti-epileptic agents with improved safety profiles.

Authors: Kose Hazal Deniz , Seker Oya
Published: April 2024

This study investigated the effects of different solutions (artificial saliva, Listerine Cool Mint-alcohol containing and Colgate Plax-alcohol free) on the nanohardness, elastic modulus and surface roughness of enamel surface and composite materials (Admira Fusion, Clearfil Majesty Esthetic and Mosaic Universal). Specimens of 2 mm depth and 5 mm diameter were stored in solutions for 12 h at 37�C. Baseline and final measurements were obtained using a HYSITRON TI 950 TriboIndenter testing machine. The applied force to each specimen increased from 0 to 1000 �N. For SEM images, one sample in each group was covered with a thin layer of mix of gold and palladium using a sputter coater (Quorum Q150R ES, UK). Scanning electron microscopy (SEM) images were taken at 5000� magnifications to evaluate the surface morphology. Statistical analysis for hardness, elastic modulus and roughness was performed by Two-way ANOVA, Benferroni and Tukey HSD at a significance level 0.05. The results of this study showed that the highest value of surface roughness and lowest hardness and elastic modulus were presented by Admira (p[0.001). Listerine caused significantly increased surface roughness (p[0.001) and decreased hardness and elastic modulus parameters (p[0.001). The mouthrinse containing alcohol caused more significant changes in the nanohardness, elastic modulus, surface roughness values of enamel and composite surfaces.
Preparation and Modification of Flexible Polyurethane Foam for Effective Flame Resistance and Sound Absorption
Authors: Ji Xin , Chen Mingxuan , Jiang Xueliang , You Feng , Yao Chu
Published: April 2024

Polyurethane foam as an important sound absorption material is limited by the poor flame resistances in building field, but the modifications of flame resistances tend to have adverse effects on the sound absorption performance. Herein, dibutyltin dilaurate and triethylenediamine are used simultaneously as catalysts, and four new types of flame retardant polyether polyols (FPMPO) are synthesized and combined with modified expanded graphite (PEG) to prepare the flame resistance flexible polyurethane foam (FFPUF) by one-step method. The results show that the combination of the two catalysts can control the cell structure of FFPUF availably for sound absorption. The FPMPO have little negative influence on the cell morphology and the sound absorption performance of FFPUF, but the increase of flame resistances is finite due to the limited amount of FPMPO. In order to improve the flame retardant properties further, the FPMPO and the PEG are combined in the modification. Benefitting by the effective control structure and the modification with composite flame retardant, the FFPUF shows excellent sound absorption and flame retardant properties. The LOI value of FFPUF is 33.4 and the vertical burning level reaches V-0, and the average sound absorption coefficient maintains 0.68 in the 800-6300 Hz range.

The medium permeability changes in response to iron plate movement, ensuring a high-tuning range above 250%. The first inductor is designed for the 10 GHz range, and the inductance value is comprised of Lmin = 3.37 nH and increases to Lmax = 11.8 nH. Similar inductance values are obtained for the second inductor, but it is designed to work at 20 GHz. Furthermore, the maximum value of the quality factor of the second inductor is slightly higher than the first one and reaches Qmax = 17.5.
Design and Comparison of Constant Transconductance Architectures
Authors: H. L. Rajath Ithal , N. Shylashree , A. S. Mamatha , B. G. Nikhil
Published: April 2024

Constant transconductance (Gm) biasing circuits, as the name suggests, generate a bias current that ensures that the Gm of a MOS transistor remains constant. The Gm of a MOS transistor is a very important parameter as various other parameters of a circuit such as the gain, UGB (Unity Gain Bandwidth, poles, and zeros are strongly dependent upon it. Every analog circuit in a chip is subjected to varying PVT (Process, Voltage, and Temperature) conditions. This leads to a varying Gm of the devices, and hence the parameters such as the gain and UGB also tend to vary. Hence, constant Gm biasing is crucial in systems, where the parameters are expected to be constant regardless of the external factors. The majority of constant Gm biasing circuits make use of an external off-chip resistor. While this is a reasonable solution, it adds to the cost, area, and complexity of the solution. Hence, it is vital to model and design all the required functionalities within the chip, eliminating the requirement for any external components. In this paper, different architectures of constant Gm biasing circuits are designed and simulated in Cadence Virtuoso software. The proposed architecture has an error of 6.42% in the variation of transconductance, which is a significant improvement concerning the other architectures simulated. Additionally, the proposed architecture does not require any off-chip components while the other architectures require an off-chip resistor. Hence, the proposed solution has reduced cost and complexity.

Published: April 2024

The article is devoted to the legal regulation of the procedural procedure for the restoration of rights on lost documentary securities with an emphasis on their type as order securities. The author analyzes civil and procedural legislation, the opinions of scientists and the judicial practice of courts of general jurisdiction and arbitration courts on the issue of the applicability of call-out proceedings to the restoration of rights on a lost order security. The author comes to the conclusion about the inconsistency of civil and procedural legislation in the issue of the procedure for restoring rights to a lost order security, which is clearly confirmed by judicial enforcement. The amendments introduced in 2013 to the Civil Code of the Russian Federation to this procedure have been interpreted ambiguously and inconsistently for ten years, there is no unity in understanding the procedure for restoring rights under such documents by the courts, which cannot but affect the effectiveness of justice related to the protection of the rights of persons who have lost an order security. In conclusion, it is concluded that the identified inconsistency in the legal regulation of the procedure for restoring rights on a lost order security needs to be eliminated, but before the relevant legislative changes, explanations are needed from the Supreme Court of the Russian Federation on the applicability of summoning proceedings and the ratio of the provisions of paragraph 2 of Article 148 of the Civil Code of the Russian Federation and Chapter 34 of the Civil Code of the Russian Federation. The methodological basis of the article consists of general scientific (analysis, synthesis, analogy, description, system) and private scientific methods (comparative legal, formal legal).

Published: April 2024

Tutkimuksessa selvitettiin pelastusalalla saatua psykososiaalista tukea ja sen lähteitä, tuentarpeita sekä esteitä tuen hakemiselle ja saamiselle. Tutkimuksen kohderyhmänä olivat pelastuslaitosten työntekijät, jotka olivat osallistuneet posttraumatyöpajaan keväällä 2021 (n = 15). Aineisto kerättiin yksilöhaastatteluilla kuusi kuukautta posttraumatyöpajan jälkeen. Aineisto analysoitiin induktiivisella sisällönanalyysilla. Tulosten mukaan psykososiaalista tukea saadaan organisaatiolta, esihenkilöiltä, kollegoilta, läheisiltä ja ulkoisista palveluista, mutta tuki jää monin osin vaillinaiseksi. Tuen hakemista ja saamista vaikeuttaa mielenterveysasioihin liitetty stigma, ja tärkeänä pidetään sitä, että auttajalla olisi pelastusalan toimintaympäristön tuntemusta. Pelastusalan posttraumatyöpajan vakiinnuttamisen lisäksi kehittämiskohteeksi nousee olemassa olevien muiden tukimuotojen vakiintuminen ja systematisoituminen osana psyykkisen avun palveluita.

 

Abstract

Sources, needs and challenges of psychosocial support in emergency services

This study examined psychosocial support and its needs and barriers in seeking and receiving support in emergency services in Finland. The target group was emergency service workers (paramedics and firefighters) who had participated in the Post Critical Incident Seminar in spring 2021 (n=15). The data was collected through individual interviews six months after the seminar. The material was analyzed with inductive content analysis. According to the results, the sources of psychosocial support are the organization and its superiors, colleagues, loved ones, and external mental health services, however, the support remains lacking in many aspects. The stigma attached to mental health issues makes it difficult to obtain successful psychosocial support. The importance of knowledge of the special work environment of the emergency services is considered important for a helper. On top of establishing Post Critical Incident Seminar, the development areas based on this study are for example settling other already existing support interventions for mental health needs and systematizing them as part of psychosocial support services.

BACKGROUND

Portal hypertension (PHT), primarily induced by cirrhosis, manifests severe symptoms impacting patient survival. Although transjugular intrahepatic portosystemic shunt (TIPS) is a critical intervention for managing PHT, it carries risks like hepatic encephalopathy, thus affecting patient survival prognosis. To our knowledge, existing prognostic models for post-TIPS survival in patients with PHT fail to account for the interplay among and collective impact of various prognostic factors on outcomes. Consequently, the development of an innovative modeling approach is essential to address this limitation.

AIM

To develop and validate a Bayesian network (BN)-based survival prediction model for patients with cirrhosis-induced PHT having undergone TIPS.

METHODS

The clinical data of 393 patients with cirrhosis-induced PHT who underwent TIPS surgery at the Second Affiliated Hospital of Chongqing Medical University between January 2015 and May 2022 were retrospectively analyzed. Variables were selected using Cox and least absolute shrinkage and selection operator regression methods, and a BN-based model was established and evaluated to predict survival in patients having undergone TIPS surgery for PHT.

RESULTS

Variable selection revealed the following as key factors impacting survival: age, ascites, hypertension, indications for TIPS, postoperative portal vein pressure (post-PVP), aspartate aminotransferase, alkaline phosphatase, total bilirubin, prealbumin, the Child-Pugh grade, and the model for end-stage liver disease (MELD) score. Based on the above-mentioned variables, a BN-based 2-year survival prognostic prediction model was constructed, which identified the following factors to be directly linked to the survival time: age, ascites, indications for TIPS, concurrent hypertension, post-PVP, the Child-Pugh grade, and the MELD score. The Bayesian information criterion was 3589.04, and 10-fold cross-validation indicated an average log-likelihood loss of 5.55 with a standard deviation of 0.16. The model’s accuracy, precision, recall, and F1 score were 0.90, 0.92, 0.97, and 0.95 respectively, with the area under the receiver operating characteristic curve being 0.72.

CONCLUSION

This study successfully developed a BN-based survival prediction model with good predictive capabilities. It offers valuable insights for treatment strategies and prognostic evaluations in patients having undergone TIPS surgery for PHT.

Objective: This study aims to identify the effects on learning for Internal Audit in mitigating the risk of corruption in companies involved in the Operation Car Wash, comparing before and after the event.

Method: This research has a qualitative approach. The population consists of seven companies, large economic groups of Brazilian origin, and with operations in various countries. The chosen sample type was non-probabilistic due to accessibility. A semi-structured interview was conducted for 6 of the respondents, and 1 unstructured interview due to presenting different characteristics from the others. The script is divided into three dimensions, totaling 41 questions, applying content analysis technique, divided into four categories, according to the theory.

Results: The results show the main lessons learned: (i) greater focus on mitigating the risk of corruption; (ii) prioritizing investments in increasing personnel, training, and technology; (iii) improvement in the efficiency and qualification of Internal Audit; and (iv) creation of business opportunities.

Originality/Relevance: highlighting that the organization can learn from the punishments to which they were subjected and, in some cases, formulate new growth strategies.

Theoretical/methodological contributions: This research is relevant for linking organizational learning with the sanctions incurred by Operation Car Wash, showing that Internal Audit plays a fundamental role in the fight against corruption and the mitigation of its risks.

Social/management contributions: Companies can use this study to develop strategically when facing any type of compliance risk.
IMPLEMENTASI PERDAGANGAN KARBON DI INDONESIA PASCA TERBITNYA POJK NOMOR 14 TAHUN 2023 TENTANG BURSA KARBON

POJK Nomor 14 Tahun 2023 tentang Bursa Karbon merupakan upaya Pemerintah untuk menciptakan pengaturan perdagangan karbon melalui bursa karbon. Sebelumnya Pemerintah mengeluarkan dua peraturan terkait perdagangan karbon, yaitu Peraturan Presiden Nomor 98 Tahun 2021 dan Peraturan Menteri Lingkungan Hidup dan Kehutanan Nomor 21 Tahun 2022. Namun ternyata peraturan ini masih terdapat kelemahan. Penelitian ini merupakan penelitian hukum normatif. Hasil penelitian menunjukkan Setelah berlakunya POJK tentang Bursa Karbon masih terdapat kelemahan dimana dasar dari modal disetor sebagai penyelenggara bursa karbon sama persis seperti aturan bursa efek yang tercantum di Pasal 3 POJK 3/2021. Ketentuan tersebut dinilai membuat bursa karbon menjadi eksklusif. Selain itu, beberapa aturan di dalam POJK 14/2023 seperti bentuk perdagangan karbon adalah efek, sehingga akan ada delisting, padahal karbon tidak ada yang namanya hilang atau delisting. Selain itu pada Pasal 27 terkait syarat dan tata cara penyelenggara bursa karbon harus memenuhi prinsip keterbukaan, akses, dan kesempatan yang sama kontradiksi dengan definisi karbon sebagai efek. Hal ini dikarenakan apabil bentuk bursa karbon sudah menjadi efek, maka yang akan masuk juga para pemain bursa efek. Sehingga pengaturan ini belum menjelaskan siapa yang bisa terlibat dalam perdagangan karbon selain penyelenggara. Individu, koperasi, komunitas, LSM bisa terlibat dalam perdagangan karbon atau tidak,
