Introduction: Vasectomy or male sterilisation is a procedure that consists of cutting the vas deferens to prevent the passage of spermatozoa into the seminal fluid. There are several factors that cause men to have misconceptions that foster a negative attitude towards this procedure, such as, for example, the deformity of the reproductive system, decreased and consistent ejaculation, among others. Objective: To determine the levels of attitude towards vasectomy held by men in the Port of Veracruz. Methodology: Research of non-experimental design, with a quantitative, descriptive and cross-sectional approach; the study sample consisted of 200 men, the instrument used was Attitudes and Beliefs towards Vasectomy which reported an alpha of 0.85. Results: It was determined that 69% of the study sample expressed a neutral attitude towards the procedure; on the other hand, in relation to attitude and level of schooling, 55% of the participants who expressed a positive attitude had a bachelor's degree level of education; finally, the association with age and attitude towards the problem showed that 60.9% of those aged 25-34 years expressed a positive attitude. Conclusion: It is concluded that for this study the majority of the participants expressed a neutral attitude, it is therefore important to continue working on health education and promotion.

Introduction: Given the current events of the Russian-Ukrainian war, post-traumatic stress disorder (PTSD) is one of the most common psychological problems among military personnel, which requires the introduction and use of new techniques of psychological rehabilitation.Objectives: The study aims to develop and test a comprehensive programme for psychological rehabilitation of military personnel and determine its effectiveness.Methods: The study was conducted among 30 military respondents diagnosed with PTSD. The experiment used pre-test and post-test data from participants at three different time points: pre-intervention, two weeks post-intervention, and four months post-intervention—main instruments: Military PTSD Checklist and Patient Health Questionnaire (PHQ-9). For mental health assessment, 3 scientifically validated indicators were used for data analysis: PCL-M, PHQ-9, and GAD-7.Results: The results demonstrate the need to implement a comprehensive psychological rehabilitation programme for military personnel. If, at the beginning of the test, they were diagnosed with PTSD, acute depression and anxiety, then after two weeks of implementing the comprehensive programme, the indicators decreased significantly. After 4 months, the scores rose slightly but not significantly. This demonstrates the relevance and importance of using various activities to support the psychological state of military personnel who have experienced difficult and traumatic periods. Conclusions: The conclusions summarise that recovery from PTSD requires a comprehensive approach that should consider the internal and external characteristics of each patient

Published: December 2024

Business decisions taken by the Board of Directors are solely an obligation for the Board of Directors so that SOE can grow sustainably, stably, and have high competitiveness, but an unavoidable reality is that a business entity does not only experience profits, but is also faced with phases of loss. Business decisions that have been made with full calculation and prudence are still not free from business risks that can result in the SOEs they manage experiencing losses, so that they are categorized as detrimental to state finances and lead to criminal justice processes. This study aims to (1) analyse losses in SOEs that can be qualified as state financial losses and (2) analyse what business decisions made by the President Director of SOEs are categorized as fulfilling the elements of corruption in criminal cases in the Central Jakarta District Court Decision Number 15/Pid.Sus-TKP/2019/PN.Jkt.Pst. This research uses normative juridical research methods using statute approach, conceptual approach, and case approach. The results showed that separated state assets are state assets originating from the state budget to be used as state equity participation in SOEs. State assets that become capital in the form of shares are no longer state assets. State assets in SOEs are limited to the ownership of the company's shares, so that if there is a loss in the SOE Persero, this is not a state loss, but a loss of the SOE. The business decisions made by the President Director of the SOE are categorized as fulfilling the elements of corruption due to a series of actions by Karen that do not entirely reflect the principle of prudence in making decisions, nor do they fully fulfil the elements of Article 97 paragraph (5) of the Limited Liability Company Law.

Bionadzor u vreme „nove normalnosti“

Published: December 2024

Bionadzor u vreme „nove normalnosti“ u sebi sadrži apstraktne forme panoptikuma, kao kategorija moći sa disciplinskom funkcijom u cilju nametanja određenog ponašanja i iskorištavanja moći ljudskog kapitala koji obuhvaća biopolitičko tijelo s jedne strane, u Foucaultovoj perspektivi i, s druge, društvenu kontrolu, kako je vidi Deleuze. U kapitalizmu biokontrole, kapital korporacija u sebi objedinjuje kontroliranu, disperzivnu, sveobuhvatnu i sveprisutnu umreženu moć. Biokontrola nad pojedincima ne provodi se samo kroz ideologije već i kroz svijest i u tijelu i nad tijelom u spektaklu straha i medijskog programiranja, kroz sve aspekte društvenog života. Novo normalno“ doba je vrijeme socijalnog inžinjeringa i prikrivenog biološkog i psihološkog rata.Radom se dokazuje da je tehnokracija ovladala svakim aspektom bionadzora u društvu jer posjeduje instrumentarnu moć koja teži instrumentalizaciji ponašanja, modifikaciji, predviđanju, kontroli. Kroz bionadzor tehnokracija teži stvaranju poslušnog podanika i dominaciji privatne sfere domenama javnog interesa. Tehnokracija je ovladala suverenom moći koja traži poslušnost, disciplinskom koja zahtjeva pokornost i regulativnom koja zahtjeva pokoravanje i potčinjavanje zdravlju stanovništva kroz organizirani sustav psihološke intervencije i zakonodavnih normi.

In the context of the quality of elections, transactional politics and money politics have always been a bug in the quality of elections in Indonesia. In the context of election law enforcement, including related to transactional politics, Bawaslu is an institution established to enforce election law, including money politics. Unfortunately, various data show that money politics is still the dominant political strategy in elections. This research seeks to prove that there is an implementation gap between Bawaslu's authority in enforcing electoral law and the existing reality and find out what factors cause the implementation gap. In addition, this research seeks to provide recommendations regarding the existing implementation gap. This research uses descriptive qualitative research with data collection methods of literature study and document study which are correlated with the existing theoretical basis. The result of this research is that there are several things that cause the implementation gap such as the difficulty of defining money politics which is a systemic problem in policy capacity theory. The recommendations presented in this study are First, the need to strengthen the role of Bawaslu as an election supervisory institution by providing more comprehensive authority in the investigation and examination process. Second, there is a need for a firmer and clearer legal change related to money politics, as well as an increase in sanctions for violators.

Published: December 2024

The first principle calculation was employed to investigate the formation energies and structural, electronic, and magnetic properties of intrinsic and Ni-doped sodium bismuth titanate Bi0.5Na0.5TiO3 (BNT). The obtained formation energies indicate that Ni atoms prefer to dope into Bi-sites in the lattice of BNT while the calculated band structure shows that the doping leads to the emergence of new mid-gap energy states in the bandgaps, reducing the bandgap value of doped materials. The PDOSs reveal that Bi-6p, O-2p and Ti-3d contribute major parts in BNT valence and conduction bands, while the Ni-3d and 4s play the main roles in the formation of new mid-gap states. The spin-resolved density of states, the integrated spin densities and the charge distributions suggest that all doped models exhibit magnetic behavior, mainly due to the interaction of Ni, O and Ti atoms. The study method of this research can be applied to predict new properties of BNT-based materials.

Polyethyleneimine (PEI) is a novel polymer that contains multiple amine groups that are suitable for chelation with many heavy metal ions (HMI). Anchoring PEI onto the surface of a solid substrate has been widely adopted to develop adsorbent materials with the hope of combining the HMI chelating ability of PEI with the heterogeneity of the substrate. Herein, the preparation of PEI grafted SiO2 (PEI/SiO2) has been demonstrated by a stepwise method in which SiO2 nanoparticles were functionalized with 3-glycidoxypropyltrimethoxysilane (KH560) followed by refluxing with PEI. The method could provide PEI/SiO2 material with 23.4% of PEI by weight. Studying the adsorption properties of PEI/SiO2 with Cu(II) revealed that the adsorption of Cu(II) ions on PEI/SiO2 followed Langmuir and Dubinin-Radushkevich models and included both chemisorption and physisorption. The adsorption capacity was about 25.3-27.3 mg/g. The stepwise method demonstrated in this study may be adopted to fabricated PEI based materials for HMI removal.
On minimization of quadratic functions over closed convex sets in Hilbert spaces
Authors: Tran Van-Nghi , Nguyen Nang-Tam , Le Chi-Thanh
Published: December 2024

Quadratic programming problems are of primary importance in various applications and arise as subproblems in many optimization algorithms. In this paper, we investigate quadratic programming problems in Hilbert spaces. By utilizing the Legendre property of quadratic forms and an asymptotically linear set with respect to a cone, we establish a sufficient condition for the existence of solutions to the considered problems through a Frank-Wolfe type theorem. The proposed condition is based on the special structure of Hilbert spaces, extending the applicability of quadratic programming methods. Finally, we provide a numerical example to illustrate the results obtained and demonstrate that existing approaches cannot be applied in certain cases.

The synthesis and photoluminescence study of Dysprosium (Dy) doped Calcium Gadolinium Borate Ca3Gd2(BO3)4:Dy3+ are presented in this research. The aim of this study was to investigate the optical properties and potential applications of Dy-doped Calcium Gadolinium Borate as a luminescent material. The samples with Dy+3 doping have been synthesized by the solid state reaction method at varying concentration of Dy+3 ions. The phase purity of the synthesized samples was confirmed from the X-ray diffraction where single phase orthorhombic structure was obtained. The UV excitation photoluminescence spectra of synthesized samples and emission peaks referring to the energy transition of Dy+3 ions are identified. Here, different emission intensities and the shift in the peaks position with reference to change in the Dy+3 concentration were analyzed, and the maximum luminescence intensity was observed at the best dopant concentration. This is made evident from this concentration-dependent behavior which suggests that energy transfer from the host lattice to Dy+3 ions is highly efficient. Therefore, the present work is a successful path towards Dy-doped Calcium Gadolinium Borate as a luminescent material. Due to its property this material seems to have good application potential in solid-state lighting, display and opto-sensing.

Taxes are crucial because the government uses them to fund public welfare and development. Tax revenue in 2022 demonstrates an equally dispersed economic recovery in Indonesia across a number of industries. However, due to a number of factors, including instances of tax avoidance and corporate practices that exploit technicalities in tax laws, Indonesia's tax collection has fallen short of its proper amount. This study sought to ascertain how tax evasion affected the company value of coal mining businesses that were listed between 2018 and 2021 on the Indonesia Stock Exchange. Panel data regression analysis techniques are employed in the data analysis method using the Eviews version 12 software. Choosing model estimates the Chow test, Hausman test, Langrange multiplier test, normality test, panel data regression test, and hypothesis testing is how data testing is done. The analysis concluded that there is no relationship between tax avoidance and corporate value.

The aim of the study was to evaluate the efficacy of treatment with the use of the Tergumed 700 system in a group of males with low back pain (LBP) syndrome based on the dynamics of changes in the isometric strength of the lumbar spine muscles and the imbalances thereof. Thirty-six males were examined, 19 in the study group (A) and 17 in the control group (B). Magnetic resonance imaging (MRI) of the lumbar spine was applied to assess the degree of degenerative changes. The isometric strength and imbalance of the lumbar spine muscles were tested using the Tergumed 700 system. In the study group (A), traditional Richardson’s core stabilization exercises and therapy with the Tergumed 700 system were performed. In the control group (B), only Richardson’s core stabilization exercises were conducted. The therapy lasted 6 weeks. The examination was performed four times: before the therapy, and after 2, 4, and 6 weeks following the therapy commencement. After six weeks, in the test group (A), the lumbar extensor muscle strength (p = 0.006), left-sided rotator muscle strength (p = 0.015), and right-sided rotator muscle strength (p = 0.001) improved. However, in the control group (B), significant improvement after the same period was found only in the lumbar extensor muscle strength (p = 0.042). As a result of the programmed treatment based on the patient’s current condition test, the lumbar back pain syndrome therapy using the Tergumed 700 system combined with central stabilization exercises according to Richardson was found to be most effective.

Background: Diabetic foot ulcers (DFUs) are a severe diabetes complication with a burden similar to cancer. Risk factors include peripheral neuropathy, arterial disease, foot abnormalities, and socioeconomic and geographical influences. Low-Level Laser Therapy (LLLT) relieves pain, promotes tissue repair, and aids wound healing. Ultrasound therapy enhances circulation and tissue healing through sound waves. Buerger-Allen Exercises (BAE) improve lower extremity perfusion, aiding wound healing and reducing neuropathy symptoms. Purpose: This pilot study compared the effectiveness of LLLT with BAE versus Low-Intensity Pulsed Ultrasound Therapy (LIPUS) with BAE in managing DFUs. Methods: 40 patients were assigned to two groups (20 each). Group A received LLLT for 10 minutes, while Group B received LIPUS for 10 minutes. Both groups performed BAE for 10 minutes on alternate days, 3 days a week for 12 weeks. Outcomes were assessed using the Visual Analog Scale (VAS), Bates-Jensen Wound Assessment Tool (BWAT), and Diabetic Foot Ulcer Scale (DFS). Results: Both groups showed significant improvements (P ≤ 0.05), but LLLT with BAE was superior in pain reduction, wound healing, and quality of life. Conclusion: LLLT with Buerger-Allen exercises is a more effective treatment for DFUs than LIPUS.

Authors: Sivanandam Murali , Jothilingam Muthukumaran , Purushothaman Senthil
Published: December 2024

Background. Myofascial pain syndrome is a condition characterized by muscle injury that results in the development of trigger points. Compression, stretching, overloading, or contracting of trigger points can lead to hypersensitivity and pain in taut bands of skeletal muscle. These points can cause referred pain that is felt away from the trigger point and may also restrict movement and limit functional activities. Treatment of myofascial pain syndrome should address trigger points as part of a comprehensive treatment program. Various interventions, both manual and non-manual, are available to help deactivate trigger points and alleviate associated pain and discomfort. Objective. This study seeks to investigate the latest research on myofascial trigger points and evaluate the effectiveness of integrated neuromuscular inhibition. Method. The effectiveness of Integrated Neuromuscular Inhibition on myofascial trigger points in the general population was assessed through a systematic literature review. Using the PEDro methodological quality scale, two authors independently evaluated the methodological quality of each randomized controlled trial. In order to identify articles meeting the inclusion criteria, the primary researcher reviewed their titles and abstracts. Results. In comparison with alternative interventions, an integrated approach (INIT) for treating TrPs in patients with neck pain has demonstrated greater efficacy in reducing pain, improving functional ability, and reducing disability while enhancing quality of life. Conclusion. The findings of this review add to the growing body of evidence endorsing the use of INIT for individuals with active TrPs.
