Authors: Bessa G. Pacelli , Jorge Luquesio P. , Pessoa Leandro F.
Published: June 2024

We prove a version of the strong half-space theorem between the classes of recurrent minimal surfaces and complete minimal surfaces with bounded curvature of

\mathbb{R}^{3}

. The use of subsolutions in the barrier sense allow us to deal with non-proper minimal surfaces immersed with bounded curvature. We show that any minimal hypersurface immersed with bounded curvature in

M\times \R_{+}

equals some

M\times \{s\}

provided

M

is a complete, recurrent

n

-dimensional Riemannian manifold with

\textup{Ric}_{M} \geq 0

and whose sectional curvatures are bounded from above. Furthermore, we prove a half-space theorem for the class of stochastically complete

H

-surfaces. We present a maximum principle at infinity assuming

M

has non-empty boundary. Finally, we present examples of a complete non-proper recurrent minimal surface with unbounded curvature.

Published: June 2024

Brucellosis is a zoonotic disease with worldwide distribution. In Eritrea, the status of the disease in occupationally exposed dairy farmers is unknown. The objective of this study was to determine the seroprevalence of brucellosis, level of knowledge, and risky practices of dairy cattle owners/workers in Maekel and Debub regions, Eritrea. A cross-sectional study was conducted between August 2021 and February 2022. A total of 416 dairy cattle owners and workers underwent blood collection and interview using a standardized questionnaire. Blood samples were tested using Rose Bengal Plate Test, and positive samples were confirmed using competitive ELISA. Variation in knowledge scores by sociodemographic factors and practices were explored statistically. The apparent and true seroprevalence was 1.2% (95% CI: 0.05–2.8%) and 1.4% (95% CI: 0.6–3.4%), respectively. Apparent seroprevalence was similar in Maekel (1.1%) and Debub (1.2%) regions. Nearly half of the participants (49.5%) had never heard of brucellosis before. Overall, brucellosis knowledge score was low (mean score: 6.53/20). Knowledge score was higher in participants from Maekel region (P <0.001), older participants (P = 0.035), those with higher educational attainment (P = 0.001), and those with more years of experience working in dairy farming (P = 0.001). Knowledge score was lower in farm workers compared with family members (P = 0.016). No significant differences in knowledge score existed between participants who engaged in or did not engage in potential risky practices. In summary, the prevalence of brucellosis in dairy cattle owners/workers in Maekel and Debub regions, Eritrea, was low. Participants demonstrated limited knowledge of brucellosis and engaged in risky practices.

Published: June 2024

Chagas disease is an underrecognized, chronic, and potentially life-threatening disease caused by the parasite Trypanosoma cruzi. We aimed to improve awareness and screening for Chagas disease among patients from endemic areas using a large safety-net academic hospital system in the United States. We developed an educational intervention consisting of a case-based didactic session presented to physicians, trainees, and other healthcare providers at conferences across different departments. Performance on a knowledge assessment administered before and after the presentation was analyzed with paired Student’s t-test for within-subject difference testing. Institutional testing rates for T. cruzi were evaluated for an equal time period (29 months) before and after the start of the intervention. Testing rates were compared by a Welch’s unequal variances t-test and by interrupted time series based on multivariate linear regression. Eleven educational sessions were held over the intervention period, and 103 participants completed the pre- and post-presentation surveys. The mean survey scores were 59.2% before the presentation and 96.6% after presentation (P <0.001). Trypanosoma cruzi testing during the postintervention period was significantly higher than testing during the pre-intervention period (171 patients pre-intervention versus 378 patients postintervention [P = 0.015]). Notable increases in testing from the pre-intervention to postintervention periods occurred among midwives (1–68 patients tested) and trainees (57–133 patients tested). Overall, 56/537 (10.4%) nonduplicate T. cruzi commercial screening tests were positive. Testing increased over time, both at an institutional level and within targeted departments. In addition to the educational program, other factors likely influenced expanded testing.
Predictors of Mortality in Crimean-Congo Hemorrhagic Fever Patients Admitted at a Tertiary Care Hospital in Pakistan over the Last 10 Years: A Case-Control Study
Authors: Sethi Sher M. , Zahid Soha , Nasir Nosheen
Published: June 2024

The objective was to identify predictors of mortality in hospitalized patients with Crimean-Congo hemorrhagic fever (CCHF). A case-control study was conducted on patients hospitalized with CCHF from 2012 to 2022. Risk factors for mortality in CCHF patients were analyzed using logistic regression. A total of 86 patients with a median age of 36 years (interquartile range [IQR], 27–36 years) were included, and the majority were males (78, 90.7%). Thirty-one patients (36%) were cases, whereas 55 (64%) were control patients. Based on univariate logistic regression analysis, patients who were in an age group of ≥40 years (odds ratio [OR]: 4.85; 95% CI: 1.8–12.4) or with presence of gum bleeding (OR: 2.66; 95% CI: 1.0–6.8), unit increase in white blood cell count (WBC) (OR: 1.09; 95% CI: 1.00–1.07), serum glutamate-pyruvate transaminase of ≥500 U/L (OR: 3.68; 95% CI: 1.4–9.3), serum glutamic-oxaloacetic transaminase (SGOT) of ≥1,000 U/L (OR: 8.72; 95% CI: 2.6–28.3), prothrombin time (PT) of ≥120 seconds (OR: 9.85; 95% CI: 3.2–29.8), international normalized ratio of ≥5 (OR: 15.8; 95% CI: 2.0–125.3), or acute respiratory distress syndrome (ARDS) (OR: 28.27; 95% CI: 5.84–136.9) were found to be significantly associated with mortality in CCHF. Factors found to be independently associated with mortality on multivariate analysis included ARDS (adjusted OR [aOR]: 27.7; 95% CI: 4.0–190.5), unit increase in WBC (aOR: 1.02; 95% CI: 1.02–1.26), SGOT of ≥1,000 U/L (aOR: 23.6; 95% CI: 2.32–241.7), and PT of ≥120 seconds (OR: 10.2; 95% CI: 2.00–52.4). CCHF is a rare but fatal disease, and patients with ARDS and increased WBC, high SGOT level, and increased PT indicative of liver injury and coagulopathy at the time of hospitalization are at high risk for mortality.

Authors: Satoh Susumu , Tosaka Akio , Kato Toshiyuki , Shinozaki Masatoshi , Obara Takashi , Nishida Minoru
Published: June 2024

Metallurgical factors affecting the press formability of the newly developed high strength sheet steels have been discussed. Dual phase steels, CHLY(cold-rolled sheet steel) and HTP-D(as-hot-rolled sheet steel), produced by control of cooling conditions after intercritical annealing or hot-rolling exhibit very low yield to tensile strength ratio and high n-value. Rephosphorized extra-low carbon steel, CHRX, produced by continuous annealing with rapid cooling is characterized by its extremely high r-value and low yield strength. CHLY, HTP-D and CHRX have large bake hardenability. Precipitation hardened steel, HTP-F(hot-rolled sheel steel), produced by adjusting carbon equivalent and sulfur content is suitable for manufacturing wheel rims owing to its good formability after flash butt welding.

Application of a Mass Airflow Sensor to the Automotive Environment
Authors: Bremer Richard J.
Published: June 2024

Mass Airflow Sensors (MAS) are being applied in increasing number to fuel injected engines. The primary reason for this is desensitization of intake air measurements to engine variation along with improved accuracy with altitude and temperature changes. When applying a MAS to a fuel injection system, a number of considerations must be addressed to insure a quality measurement is obtained. This paper will discuss the operation of the GM hot film mass airflow sensor and overview its application to fuel injected engines.
Analysis and Estimation of Fuel Consumption in Urban Traffic
Authors: Shima Junkoh , Hirose Tomoji
Published: June 2024

From the multivariate analysis on the actual data collected in urban driving, it was shown that average trip time was the single most important factor in explaining the variability of fuel consumption. The theoretical approximation model was derived in terms of physical properties of engine-vehicle systems and the relationships among the traffic related parameters and ten factors including the trip time were identified. Paying attention to the average trip time, the fuel consumption estimation model was verified using the traffic detector data to be in comparatively good agreement with the actual fuel consumption.

Published: June 2024

The unique minicar in Japan is subject to various legal restrictions regarding body size, engine volume and seating capacity, and loading, while it is given privilege with regard to tax and insurance. And today it is not merely an even smaller version of small-size vehicles. It is independently viewed as an economical vehicle for which technical efforts have been undertaken to ensure functional and performance equality to small-size vehicles. And these efforts are successfully in progress resulting in the feature of smallness remaining intact. In other words, the Japanese minicar is in the process of improving high-speed capabilities with general equality being maintained to that of small-size vehicles regarding interior space and urban travel.

Animated designs revisited – a case study under EU design law
Authors: Hartwig Henning
Published: June 2024

In view of the ongoing extensive review of EU design law and given the expected abandoning of the current seven-view limit, revisiting protection of animated designs under EU law and practice (and limits to such protection), particularly against the famous-infamous Candy Crush Graphical User Interface (GUI) dispute, allows for some fascinating conclusions with respect to a proper distinction between ‘partial designs’ and ‘parts of a design’, the correct identification of the relevant prior art, the determination of the subject matter of a design, and the finding of infringement. Overall, ‘less’ is apparently ‘more’.
A systemic crisis: political consequences of the 1989 Tiananmen square events
Authors: Zuenko I. Yu.
Published: June 2024

The article attempts to revise the understanding of the nature of China’s 1989 Tiananmen Square crisis and its consequences in the context of comparison with Soviet/Russian history of 1980-1990s. Several dozens of studies and op-ed pieces focused on the problem earlier (especially in Russian-language literature) but these papers lacked Chinese sources, intended to liken the Tiananmen Square crisis to the Russian agenda, and simplified complicated cause-effects relations of the Chinese historical process. As a result, the conclusions are limited to the question of the necessity of a decisive crackdown on any turmoil or political manifestation as a sole tool to protect one nation’s stability and prosperity. China’s stability and prosperity after the Tiananmen Square Crisis should not be seen as a result of crackdowns. Paradoxically, despite the conservatives’ victory in 1989, China got back to the path of reforms several years after the Tiananmen Square events. It can be attributed to the complex set of internal and external factors, and the freezing of China’s political reforms was just one of them. Moreover, the process was facilitated not only by overcoming its political crisis but also by observing the revolutions of 1989 in Eastern Europe. Faced with the threat of being ousted from power, China’s elites consolidated – a factor that became crucial for the implementation of systemic market reforms in the 1990s. The author concludes that a similar situation was observed in post-Soviet Russia in 1998-2000: the Russian financial crisis and several events including Second Chechnya Campaign became the ‘backbone crisis’ of Vladimir Putin’s presidency.
UAE Foreign Policy Identity: Authoritarianism, Cosmopolitism, Connectivity
Authors: Tyukaeva T. I.
Published: June 2024

The article explores the phenomenon of the foreign policy identity of the UAE, an oil-producing nation in the Persian Gulf that has managed to overcome the constraints of its smallness and assert its prestige on a global scale. The study aims to identify historic and cultural basis of the shaping of this identity, the monarchy’s perception of threats and challenges and its ways of dealing with them, the role of political leadership and how their personal views and ambitions shape the contours of the country’s self-positioning as well as the use of the foreign policy identity in implementing national interests. The author discovers that the core of UAE foreign policy identity was contoured by the founding fathers of the small monarchy and then later developed and adapted by the new generation of ambitious, charismatic, and visionary leaders. The key factor was the fusion of visions of rulers of the two emirates with most economic and political weight in the federation, Abu Dhabi and Dubai, that defined the regional and international status of the UAE as an influential and powerful actor. The paper concludes that the main components of UAE foreign policy identity are pragmatism, prioritization of socioeconomic development and prosperity, perfect combination of conservative governance and cosmopolitism, the principles of connectivity and integration in global financial and logistic networks and flows, as well as agility in the currently changing balance of power and skillful interpretation of international norms and discourses in promoting its own image and agenda.
The Rise of De Facto State’s Foreign Policy Identity: From Self-Proclamation to International Legal Subjectivity. The Case of Abkhazia
Authors: Pavlova A. V.
Published: June 2024

The article focuses on the foreign policy identity of the de facto state, citing Abkhazia, which gained partial recognition from Russia and a number of other states, as an example. Using comparative analysis of the Abkhazian Intellectuals’ Adresses (1977 and 1988) and content analysis of the annual Presidential Addresses as basic research methods, the study attempts to answer the question: what is the foreign policy identity of the de facto state (from 2008 – partially recognized state) under issue. The conducted research concludes that the conceptual foundations of Abkhazian foreign policy identity, formulated in the Intellectuals’ Addresses, are reflected in the oﬃcial discourse and reproduced at the level of everyday perception, still they are not static. The main implication to be made is that although today Abkhazia is increasingly positioned as a sovereign state, the opposite – Abkhazia’s identity as a de facto state – is still evident enough in oﬃcial speeches and everyday communication.

Published: June 2024

Social and political theory recognizes several conjunctural, as well as long-term factors that shape how citizens conceptualize democracy and what they expect from it. Based on Round 10 of the European Social Survey, we analyse how Europeans view and evaluate democracy, distinguishing liberal (basic) model and several additions, such as social-democratic, participatory and populist models (that we analyse integrated as alternative model of democracy). We explore whether liberal and alternative models of democracy are mutually complementary or exclusionary, and which model prevails, but also to what extent there are discrepancies between the normative elements and evaluated outcomes. The paper examines whether and how the length of historical experience with democracy (operationalized through different waves of democratization) influences the predominant normative of democracy, as well as evaluations of the implemented standards. Finally, in the last section, the aim of the analysis is to draw conclusions on the profile of both proponents of liberal and alternative models of democracy but also of critical citizens, who value democracy as an ideal, while remaining wary in terms of its empirical manifestations.
Civil Disobedience or Not – The Case of Road Blockades in Serbia
Authors:   University of Nis, faculty of Philosophy, Stojanović Djurdjica
Published: June 2024

The aim of this paper is to answer the question whether the road blockades that took place in Serbia in November and December of 2021 could be characterized as an act of justified civil disobedience. The answer comes from the analysis of the arguably most influental and well-known conception of civil disobedience that can be found in contemporary political theory – the conception that was proposed by the American political philosopher John Rawls. I will argue in support of the thesis that the blockades were an act of justified civil disobedience because they fit the definition of civil disobedience and meet all the conditions for a justified act of civil disobedience that Rawls presented us with.
Investigation on the Performance of UPQC System based on Five and Seven-level NPC Inverter Topologies
Authors:   Electrical Engineering Department, CRNB, 180 Aïn-Oussera, 17200 Algeria, CHENNAI Salim
Published: June 2024

This article presents an investigation on the performance of unified power quality conditioner (UPQC) system based on five and seven-level neutral point clamped (NPC) inverters, using similar strategy to identified current or voltage references and analogue control approaches for switching pulses generation via combined phase disposition-sinusoidal pulse width modulation (PD-SPWM) and fuzzy logic control scheme. The UPQC system is adopted to compensate the current source harmonics and all voltage disturbances simultaneously. It is designed by the combination of series and shunt active power filters (APFs) connected by a common DC link capacitor. The DC voltage bus is maintained constant, using proportional integral voltage controller. The synchronous reference frame (SRF) detection method is used to get the shunt APF reference signals and the instantaneous reactive power (p-q) theory for the series APF. The shunt and series active power filter (APF) reference signals, derived from the control algorithm, are injected in fuzzy controllers to generate switching signals. The functionality of both UPQC systems is evaluated using Matlab-Simulink software and SimPowerSystem Toolbox in presence of various voltage disturbances. The numerical simulation results show the efficacy of proposed UPQC based on five and seven converter topologies and confirm the superiority of UPQC system using seven-level (NPC) inerter in term of harmonic current compensation compared to UPQC system based on five-level (NPC) topologies.

It is commonly known that electric and magnetic fields of power transmission negatively and positively influence plants. Unfortunately, studies on these influences are minimal, particularly considering the comparison between magnetic field and electric field, on both DC (direct current) and AC (alternating current). This research aims to compare the influences of magnetic field and electric field, both on AC and DC, on rice plant growth. Firstly, prototypes, including the equipment, were constructed to generate AC and DC electric fields using parallel plates of a medium voltage transformer and Cockroft-Walton circuits. Meanwhile, the AC and DC magnetic fields were prepared using three different diameter current-injected coils. The rice seeds were exposed to electric and magnetic fields for one month, with plate distance and coil diameter variations. The results showed that the rice seeds grew differently according to the respective types and magnitudes of the fields. In the first two days, the rice seed growths exposed to electric and magnetic fields were higher than those without field exposures. However, since the thirteenth day, the rice growth rate with field exposure was lower than without. This study also shows that the influences of the DC electric and magnetic fields were more potent than the AC fields. The averages of rice seed growth decreasing rate for the AC and DC electric fields and AC and DC magnetic fields were 0.00827 cm/(kV/m), 0.01167 cm/(kV/m), -0.13267 cm/mT and 1.99005 cm/mT, respectively. As a general suggestion in sites, rice plants should be avoided from a transmission line due to high voltage direct current (DC) rather than that alternating current (AC).

The electrocardiogram (ECG) is a visual depiction of the electrical activity of the heart. It is utilised to detect and diagnose different cardiac conditions. Over the last decade, the categorization of cardiac conditions based on electrocardiogram signals have become very significant for both patients and medical professionals. This article presents a novel method for classifying Electrocardiogram signals into arrhythmia (ARR), congestive heart failure (CHF), or normal sinus rhythm (NSR) using combined deep learning features and optimised Support Vector Machine (Op-SVM). First, to perform classification via Deep Learning (DL)the continuous wavelet transform (CWT) was used to transform one-dimensional (1-D) ECG signals into two-dimensional (2-D) images (scalograms) which are sent then to two pre-trained convolutional neural networks (CNN) architectures (ResNet50 and DenseNet201). Next, the features extracted from both CNNs were combined and fed to the SVM classifier. To enhance the performance of the classifier, Bayesian optimisation was used to optimise its hyperparameters. The suggested method was tested using a public dataset (PhysioNet) and evaluated using performance metric techniques. It succeeded in achieving values of 99.44 % for accuracy (Acc), 99.44 % for sensitivity (Sen), 99.72 % for specificity (Sp), and 99.44 % for precision (Pr), respectively, which are exceptional compared to the values produced by models considered to be state-of-the-art. Our results showed that the suggested method is suitable for in-clinic application in diagnosing cardiac conditions using ECG signals.

Published: June 2024

Rice-fish symbiosis is an ecological farming model that can improve fish’s muscle nutrient profile and intestinal flora. We investigated the effect of rice-fish symbiosis on tilapia’s intestinal flora and muscle nutrients. We used 16S rDNA technology to analyze the intestinal flora of tilapia in pond culture and rice-fish symbiosis. Furthermore, spearman correlation analysis was performed on tilapia intestinal flora and muscle nutrients. The results showed that the contents of Valine, Phenylalanine, and Docosahexaenoic acid were significantly higher in the rice-fish symbiosis than those in the pond culture (p<0.05). Intestinal flora analysis showed that the diversity in rice-fish symbiosis was significantly higher than in pond culture (p<0.05). Meanwhile, the abundance of Brevundimonas, Pseudomonas, and Ralstonia in rice-fish symbiosis was significantly higher than those in pond culture (p<0.05), but Pirellulaceae unclassified and Cyanobium_PCC-6307 were opposite. The number of 8 predictive functional tilapia genes in the rice-fish symbiosis was higher than in the pond culture. Correlation analysis showed that the abundance of Ralstonia was positively correlated with the contents of Valine, Phenylalanine, and Docosahexaenoic acid, respectively. Our study shows that the rice-fish symbiosis could improve muscle nutrient profile and intestinal flora diversity in tilapia. This study will help to improve the rice-fish symbiosis model and provide a scientific basis for ecological aquaculture and healthy fish production.

This review investigates and contrasts the effects of various preoperative chest rehabilitation techniques in patients undergoing coronary artery bypass graft (CABG) surgery, both on-pump and off-pump. Utilizing databases such as Pedro, Cochrane, and PubMed, a comprehensive literature review was conducted, focusing on studies published between 2017 and 2023. We identified 14 relevant articles that met specific inclusion and exclusion criteria, examining the effects of preoperative physiotherapy in adult patients undergoing CABG surgery. Preoperative physiotherapy encompasses a variety of approaches, including counseling, cardiovascular exercise, instruction on breathing techniques, and inspiratory muscle training (IMT). Numerous studies have highlighted the benefits of integrating these methods, such as reducing the risk of postoperative pulmonary complications, shortening hospital stays, achieving earlier extubation, and decreasing anxiety. Despite these findings, further research is needed to evaluate the effectiveness of combination therapies, particularly those involving IMT, in preoperative physical therapy. The goal is to develop a comprehensive understanding of the mechanisms through which these treatments reduce pulmonary complications post-surgery.

This case report presents a remarkable convergence of autoimmune diseases in a young female patient who initially presented with syncope and was subsequently diagnosed with pericardial effusion-induced cardiac tamponade. Through meticulous investigation, she was found to have Hashimoto’s thyroiditis alongside an atypical presentation of systemic lupus erythematosus (SLE), marked by a unique form of antinuclear antibody positivity. Treatment involved a combination of steroids, immunosuppressants, and thyroid hormone replacement. This intricate association between intersecting autoimmune disorders, with atypical presentations and cardiovascular manifestations, underscores the complexity of autoimmune pathology and the importance of a high index of suspicion in reaching accurate diagnoses.
Rights of Victims of Hate Speech and Hate Crimes – European Standards
Authors:   Faculty of Law, University of the Academy of Economics, Novi Sad, Pavlović Zoran
Published: June 2024

The rights of victims of hate speech and hate crimes are part of the rights in the system of support for victims and witnesses of criminal acts according to domestic legislation and international and European standards. Directive 2012/29/EU foresees an obligation for member states (and candidates) to take measures to establish a protection system. Effective protection implies not only a normative framework but also real protection. The specifics of hate speech and hate crimes also conditioned the adoption of Directive CM/Rec (2022) 16, which foresees measures to combat hate speech. Some expressions of hate speech require a criminal law response, including obligations of a preventive nature on the part of public authorities. That is why encouraging individuals and groups to report hate speech and hate crimes and providing protection is part of an evolving legal culture. Victims should also be supported by the media, which in modern society often has a decisive role, through compliance with legal regulations and reporting in accordance with the rules of the profession. Social networks are an indispensable element in the policy of preventing and fighting against hate speech and hate crimes, and their role is becoming increasingly important.

Authors:   Institute of Criminological and Sociological Research in Belgrade, Tešović Olga
Published: June 2024

This article examines the role of judicial practices in supporting victims of traffic accidents, focusing on the interplay between legal frameworks, victim support systems, and societal values. Through a comparative analysis of global legal systems and an in-depth exploration of domestic laws in Serbia, the study highlights the importance of judicial sensitivity, victim participation, and the integration of public health perspectives in legal responses to traffic accidents. The research reveals substantial variability in the implementation of victim support mechanisms and underscores the potential of restorative justice practices in fostering recovery and reconciliation. Key conclusions advocate for enhanced victim participation in the judicial process, improved accessibility to support services, continuous education for judicial officials, and necessary legislative reforms to strengthen victim rights and protections. The findings aim to contribute to the ongoing discourse on improving judicial practices to better support traffic accident victims, reflecting a broader commitment to justice and human dignity.
Protection of Victims of Domestic Violence in Misdemeanor Procedure
Authors:   High Court in Šabac, Jeličić Mladen
Published: June 2024

In this paper, the author discusses the possibility of protecting victims of domestic violence in misdemeanor procedure. The provisions of the Law on Prevention of Domestic Violence and the Law on Misdemeanors were analysed. It was indicated that the protection of the victim of domestic violence can be ensured by applying a shortened or urgent procedure, because the Law on Prevention of Domestic Violence refers to the application of these provisions of the Law on Misdemeanors. The author considered the application of procedural and protective measure prohibiting access to the injured party, object or place of misdemeanor, as the basic procedural mechanism for the protection of the injured person provided by the Law on Misdemeanors. Deficiencies in the legal regulation of the mentioned measures have been identified, so the author’s conclusion is that they are not realistically applicable because the procedure for their execution is not provided. For this reason, the author proposes changing the legal provisions to enable the effective protection of victims of domestic violence.

Published: June 2024

The paper will discuss the connection between poverty and victimization of women. Instead of the usual focus on interpersonal violence, this text offers a different view of victimization. Namely, we have dealt with systemic violence which is, by definition, incorporated in social structures and which mostly passes undetected, despite leaving visible consequences. Our primary goal was to point to some of the illustrative examples of women victimization through structural violence and, besides the descriptive analysis, our intention was also to provide the reader with the explanatory analysis which led to two assumptions. The first one refers to etiology, while the second refers to systemic violence in the contemporary social context.

advanced level but the monitoring and evaluation system of these services is the data needed in planning future health development. This research aims to look at the implementation of an integrated referral system at Bumi Panua Regional Hospital. This research uses a qualitative descriptive design. The sample in this study was the service sector at Bumi Panua Regional Hospital, the Head of the Sisrute Team as the person in charge as the Key Informant and the Ordinary Informant, the doctor in charge, the Head of the medical services sector and members of the Sisrute team. The research results show that the Standard Operating Procedures (SOP) are running well, but several obstacles cause the SOP to go off the predetermined path. The referral process via SISRUTE is not yet supported by a clear and detailed SOP and flow. The application of SISRUTE has been running according to the flow set by the Ministry of Health, but there is a lack of human resources for SISRUTE operators or users at the Puskesmas, unfamiliarity with SISRUTE, accumulation of patients in the ER and errors in entering codes. In-application references cause SISRUTE flows to overlap. Conclusion: The SISRUTE application often experiences problems, routine maintenance that was suddenly carried out by the center without prior notification, server downtime, and hardware that had not been updated, which hampered referral services on the SISRUTE application and required offline or manual referrals.

Corruption crimes are not only carried out by civilians, but also occur in the military, namely the TNI (Indonesian National Army). In this situation, the civil society in question is all people, both those who work in the government and those who receive wages from the state. It is said that the TNI can commit corruption because the TNI is one of the subjects of the Corruption Eradication Law. The reason reformulation efforts are needed to regulate connectivity in cases of criminal acts of corruption is that there is a specificity given because the criminal act is different from other criminal acts in general. In terms of crime, eradicating corruption must be carried out in extraordinary ways. The ideal formulation for regulating connectivity in the case of criminal acts of corruption is that the connectivity mechanism as regulated in statutory regulations is felt to have several shortcomings, including requiring a long time, so it is felt that it ignores the principles of simple, fast and low-cost justice. So in this case the investigator prefers a split examination even though the connectivity mechanism is a mechanism that can make the case handling process into a complete series of connectivity examinations that can achieve justice for perpetrators from different jurisdictions.
