Published: October 2023

Background: Perforation is a serious complication of PUD and patients with perforated peptic ulcer often carries high risk for morbidity and mortality. Acute perforated peptic ulcer is a leading cause of generalized peritonitis and its management has continued to be a challenging task in moderate resource setting environment. Aim and objective was to evaluate the different pattern of risk factors, clinical presentations, management and clinical outcome of patients with acute perforated peptic ulcer.
Methods: This was a hospital based prospective observational study conducted in the Department of general surgery at Shri Shankaracharya Institute of Medical Sciences, Bhilai, Chhattisgarh. Total of 79 cases with diagnosis of perforated peptic ulcer treated were taken as sample size. A specially designed proforma was used to collect information on patients' demographics, symptoms, complications, duration of hospital stay and treatment outcome.
Results: In present study male predominance was seen in peptic perforation cases 68.75% and M:F ratio was 2.2:1. Mortality rate was 17.71%. Mean hospital stay among survivors was 11.8 days and among non survivors 5.5±3.73 days. Most common risk factor seen was alcohol, smoking, peptic ulcer disease and NSAIDs ingestion. Whereas the most common presentation was abdominal pain, signs of peritonitis, abdominal distension. Cases with APCHE 2 score >21 had 90% mortality.
Conclusions: The present study conclude that perforated PUD is a life-threatening disease with high morbidities and mortalities. Male predominance, smoking and alcohol consumption and pain in abdomen were the common characteristics. APACHE 2 score was useful in assessing the risk of mortality.
A rare case of large retropharyngeal pre-vertebral chordoma presented as oropharyngeal swelling
Authors: Fageeh Yahya A.
Published: October 2023

Posterior oropharyngeal swelling can result from various pathologies, including chordomas. Chordoma is a notochordal remnant origin tumor. It is a rare bone and central nervous system tumor, especially in the cervical region. Chordoma is a tumor with properties such as slowly growing and frequently recur in most patients. This case report aims to comprehensively understand the clinical presentation and radiological features of a rare C2 retropharyngeal pre-vertebral chordoma. A 24-year-old male with a two-year history of dysphagia presented with progressively worsening symptoms, including dyspnea, dysphonia, and weight loss. On examination, a large mass was observed in the posterior oropharynx. Radiologically, a large soft tissue mass involves the C2 vertebral body, extending into the pre-vertebral soft tissue and compromising the airway. The mass appears hypointense in T1 weighted images, heterogeneously hyperintense in T2, and shows heterogeneous contrast enhancement. The chordoma was confirmed through histopathological analysis, showing characteristic physaliferous cells within a myxoid stroma. Posterior oropharyngeal masses require prompt and accurate evaluation. Radiological evaluation is crucial in identifying the tumor's origin, extent, and vascularity, aiding in diagnosis and treatment planning. Surgical resection is the primary treatment, but chordomas have a high recurrence rate even after complete removal. Radiotherapy can improve survival and reduce recurrence. This case highlights the importance of multidisciplinary collaboration in providing individualized care for rare chordoma presentations.

Published: October 2023

Enterocutaneous fistula is an abnormal connection that develops between the intestinal tract and the skin with drainage of intestinal contents through the skin. Enterocutaneous fistulas secondary to intraluminal foreign body are relatively rare. We report a case of 75-year-old bedridden female on Ryles tube feeding presented with painful swelling over mild line scar of abdomen and skin opening with watery discharge from lower end of scar. Radiological imaging revealed an obstructed incisional hernia with enterocutaneous fistula likely communicating to ileum. Intra-operatively an unexpected broken tip of Ryles tube was delivered through fistula opening. Patient managed successfully with fistula excision, wedge resection and closure. This case highlights the need for adaptability and timely action during surgical intervention.

Published: October 2023

Papillary neoplasms of the biliary tract is a relatively new entity which most often comes as a histological surprise. They are often diagnosed as malignancies and are treated like that. But the prognosis is better when compared to malignancy itself. Here we reported two cases of papillary neoplasms of the biliary tract. First case was a 50 year old male who was evaluated for obstructive jaundice and on evaluation found to be type 3b hilar cholangiocarcinoma and underwent left hepatectomy with extra hepatic bile duct resection and portal lymphadenectomy. Histo-pathological report was intra-ductal papillary neoplasm - biliary type (IPN B). Second case was an incidental finding of arterial enhancing lesion in the gallbladder wall on CT scan, which was done for the evaluation of bicytopenia. This also was reported as malignancybin pre-operative imaging and hence underwent anticipated extended cholecystectomy with wedge resection of 2 cm adjacent hepatic parenchyma. Again histopathology revealed it as intra-cholecystic papillary neoplasm with focal dysplasia. Both cases were followed up for more than one and half years and showed no evidence of recurrence, hence pointing towards better prognosis. Papillary neoplasms are difficult to diagnose preoperatively and are often treated with oncological resections but they carry a better prognosis when compared with their malignancy counterparts.

Published: October 2023

Development of any swelling in the right lower chest wall or right upper abdomen is an unusual presentation. Hence the localisation of the origin of swelling becomes difficult to ascertain through clinical examination alone. Accurate diagnosis requires detailed investigation and ruling out of differentials one by one. We would like to share one such case of a patient presenting to surgery OPD with complaint of swelling in the lateral aspect of right chest wall which on investigations turned out to be a rib tumour arising from the bone marrow. Lady of age 57 years presented to us with h/o swelling in lateral aspect of right chest wall which gradually increased in size over 3 years and associated with pain for last 5 months. On exam an oval swelling of size 8×5 cm seen in lateral wall of right lower chest wall. On detailed investigations, the swelling was diagnosed as a plasma cell tumour of right 8th rib. Any chest wall or abdominal swelling needs detailed evaluation before proceeding for surgical intervention. It is important to keep various differential diagnosis in mind considering clinical factors and site of swelling to make an accurate diagnosis.

Published: October 2023

Giant renal tumors filling the entire abdominal cavity are rare in adolescents and pose a surgical challenge. Unlike their pediatric counterparts, where upfront chemotherapy can be administered without histologic confirmation, management of a giant renal tumour in adolescents follows that of the adults and is primarily surgical. Herein, we report a case of 17 years old male who presented with a 15×15 cm, 3.75 kg metastatic right renal tumour filling the entire abdominal cavity and displacing the great vessels and was managed by surgical resection, as multiple attempts of obtaining a percutaneous histologic diagnosis were unsuccessful.

Published: October 2023

Situs inversus totalis (SIT) is a rare condition with mirrored visceral organs. Biliary colic has delayed diagnosis in this cohort of patients.  Laparoscopic cholecystectomy (LC) in such condition is a technically challenging procedure and requires preoperative imaging. We report a case of a 37 years old lady with pain in left upper abdomen for last 1 year. Upon evaluation, she was diagnosed with cholelithiasis with SIT. MRCP was done to delineate the anatomy. The patient underwent LC in a split-leg position with mirrored port position by a right-handed surgeon. The duration of surgery was 90 minutes and the patient was discharged uneventfully in 48 hours and was well on one-week follow-up. LC is considered a safe surgery in patients with SIT. It requires an experienced surgeon, re-training of visual-motor coordination and modification of surgical steps.
Participación social en el sistema de salud de Chile: aportes reflexivos desde la bioética
Authors: Guerrero-Nancuante Camilo , Melo Andrea , Gundelach Paulina , Fuster Nicolás
Published: October 2023

La participación social en salud se relaciona con la capacidad de intervención de los colectivos en el sistema sanitario. Desde la bioética, se ha enfatizado en la relevancia de la participación social en salud debido a los efectos positivos a nivel de los grupos sociales, de la estructura sanitaria y de los sistemas políticos democráticos. Para asegurar la participación social en salud, la bioética aboga por la incorporación de la deliberación como herramienta para la toma de decisiones vinculantes. El objetivo del presente ensayo es reflexionar sobre la participación social en la historia del sistema de salud de Chile desde la óptica de la bioética. Las principales reflexiones indican que la participación es de tipo consultiva, sin deliberación y, por tanto, sin distribución de poder. Asimismo, la participación social fue resignificada por la etiqueta de “ciudadana”, potenciando el carácter instrumental, individual y clientelar en salud. Para subvertir esta situación, se requiere incluir reflexiones bioéticas en la estructura sanitaria con el propósito que las comunidades puedan incidir de manera consistente en el sistema de salud.
Where educators can benefit from the wisdom of clowns
Authors: McCusker Sean
Published: October 2023

There is much discourse around the need for learners to be allowed to make mistakes. This is embedded in established aphorisms such as “It’s OK to make mistakes” or “There is no such thing as a silly question”. Yet, educators themselves are often reluctant to make mistakes or appear uninformed or ‘stupid’ themselves. Conventional forms of teacher education which try to instil these values and practices, are largely unsuccessful, not least because Education is increasingly constructed as a mechanistic operation with clear measurable outcomes (Nørgård, Toft-Nielsen and Whitton, 2017) and any pedagogy which deviates from this, creates risk of failure. Into this space Design Thinking is introduced, underpinned by creative and innovative, human-centred and empathetic approaches which encourage the abandonment of preconceptions, promote improvisation and experimentation, challenge assumptions and reframe the issues at hand. The less conventional approach proposed here suggests that teachers can become more able to accept their fallibility and be familiar with risk and failure, through observing and identifying with, a profession whose success is predicated on failure, that of the clown. This article proposes that many of the principles of Design Thinking are second nature to clowns. Through inspection of the principles and practices of clowns, their applicability in the pedagogical domain is emphasised, allowing the recommendation to be made that educators should observe the performances of professional clowns and through this, learn to embody a little of the ‘clown spirit’ allowing them to be more amenable to failure, fallibility and not-knowing.

Published: October 2023

Design Thinking is gaining considerable attention across various domains including education; however its use in Executive Education has not been documented much in the literature to date. By integrating Design Thinking principles and methodologies into the curriculum for Executive learners, we highlight the benefits and outcomes of using Design Thinking as a pedagogical approach. This study explores the effective application of Design Thinking as pedagogy in two modules of an Executive MBA programme at Newcastle University Business School. Through a combination of blended learning materials and experiential, collaborative projects with client organizations, we set out how learners were immersed in a human-centred problem-solving process, developing creativity, empathy, and the ability to identify innovative solutions to complex business challenges. The study presents data gathered from client feedback and learners' reflective assessments, demonstrating the effectiveness and impact of Design Thinking as pedagogy. The integration of Design Thinking principles empowered learners to feel able to lead change initiatives within their organizations in their respective discipline areas effectively. This study contributes to the literature on effective educational approaches in Executive Education, emphasizing the potential of Design Thinking as pedagogy in practice to equip learners with the skills and mindsets necessary for driving organizational innovation and sustainability.
Using Design Thinking to Create Sustainable Communities
Authors: Barile Lory , Kelestyn Bo
Published: October 2023

This innovative practice paper discusses an example of a participatory design-led sustainability project. Using a Design Thinking approach to problem solving, the project brought together university staff and students and a Council around a local sustainability challenge. Design Thinking was applied as an interdisciplinary methodology with the objective to equip students with sustainability skills and competences, resulting in a replicable method for responding to local sustainability challenges. By empowering diverse participants to contribute equally and freely, our application of Design Thinking created positive spillover effects on students and staff sense of community. The focus of the Challenge was on the discovery and co-creation of ideas to solve a problem related to local public transport. The driving principle of the Challenge was that participants, also public transport users, could bring their own lived experience to the Challenge and therefore could co-create and put forward potential solutions with the support of a local Council, and sustainability and Design Thinking experts on campus. In the process of doing so, participants framed and reframed the challenge from different angles and perspectives, opening a co-creation dialogue about community needs on and off campus, and their role in contributing to sustainability locally.
Theoretically Rich Design Thinking: Blended Approaches for Educational Technology Workshops
Authors: Scott Howard
Published: October 2023

This paper is a reflective account that outlines the design of two Continual Professional Development (CPD) workshop sessions based on a blend of theory for design thinking about aspects of curriculum, pedagogy and technology. The theoretical approach blended aspects of design-based research, speculative design, Activity Theory and subtractive change to address issues, barriers and explore opportunities in each workshop example that is presented. The first of these workshops brought university engineering lecturers together to explore the opportunities and barriers for integrating ‘co-creation’ as a pedagogical strategy to subject teaching alongside a new interface into their curriculum. The results show how design thinking exposes limitations and challenges that prevent the realisation of pedagogically rich interventions. The second workshop brought together post-compulsory vocational lecturers to a teacher education workshop and used the same theoretical reference points to inform and antagonise the implications that Large Language Models, such as Chat GPT, present to subject knowledge, curriculum design and modes of assessment. Here these theoretically rich forms are proposed for planning use in learning design and for reshaping curricula, where academics and other professionals supporting teaching and learning may want to introduce new technologies and integrate innovative pedagogical methods or confront new challenges to their work. They may also be used as continual professional development sessions in highly participatory, practical and creative ways that allow for lucid experimentation and to imbue professionals with agency and trust.

The influence of the age factor on the contribution of the vestibular, visual, and proprioceptive sensory systems to the function of spatial orientation was assessed using the stabilometry method (ST-150, Mera, Moscow, Russia) during the vertical stance of a healthy person (N = 69, from 20 to 83 years old, of which 42 women and 27 men). Three age groups of subjects were examined: I (young, 20–25 years old, n = 37), II (middle-aged, 44–64 years old, n = 17 people), and III (elderly and old, 65–83 years old, n = 15). The subjects performed the Romberg test (stand with closed eyes) and postural stability (standing on a hard and soft surface) and a combined test (Romberg test + postural stability). This made it possible to compare the stabilometric parameters (the length and speed of the trajectory and the area of movement of the common center of pressure (COP)) under four conditions: 1) standing with eyes open on a stable surface (SS – EO), 2) eyes closed on a stable surface (SS – EC), 3) standing with eyes open on a thick layer of unstable surface (foam) (US – EO), and 4) eyes closed on a thick layer of unstable surface (foam) (US – EC). To calculate the contribution of sensory systems to the function of maintaining balance in a vertical stance, a formula was used. An increase in the length of the COP trajectory with increasing age was revealed. At the same time, only an insignificant change in the relative contribution of sensory systems to the parameters of the stabilogram was noted in middle-aged and older people compared to young people.
Horse chestnut foliar dechromation instrumental monitoring damaged by Cameraria ohridella
Authors:   All-Russian Research Institute of Phytopathology, Zhelezova S.V.
Published: October 2023

A comparison of the visual and instrumental assessments of the horse chestnut foliar dechromation degree infested by the Ohrid miner (Cameraria ohridella) was carried out. The data of surveys of model trees for the period 2014–2022 in the Moscow region are compared. A statistically reliable regression relationship between the results of visual and instrumental assessment of dechromation in a long-term series of observations is shown. Instrumental monitoring of the leaves damages during the growing season was carried out based on the assessment of the NDVI vegetation index using the GreenSeeker Handheld® (Trimble) device. The seasonal dynamics of the NDVI index of foliage under Ohrid miner damage is presented on the example of the 2021 season. It is shown that the plants affected by the pest have a shorter growing season, and the average NDVI index for the season is 25...30 % lower than that of undamaged plants. In a nine-year series of observations, it was found that the transition of the NDVI index over the threshold value of 0.4 in plants affected by the Ohrid miner is observed on average 30...40 days earlier than in healthy plants. The possibility of assessing foliage dechromation based on the results of hyperspectral imaging without visualization using the Ocean Insight «Flame» spectrometer is considered. It is shown that the spectral characteristics of the reflectivity of healthy and damaged Ohrid miner leaves differ significantly, which was demonstrated by comparing the spectral brightness curves of reflection. Characteristic spectral zones in the visible and near infrared ranges have been identified, according to which the presence of leaf damage by a miner is successfully identified. It was found that in the near-infrared radiation area, the reflection of damaged leaves are significantly lower than that of healthy leaves, which indicates a decrease in the overall water content of chestnut leaf blades when damaged by pests. According to the results of multi- and hyperspectral surveys, it is possible to automatically determine the lesion of the horse chestnut foliage by the leaf-mining pest Cameraria ohridella.

The subject of the research in this paper is the pricing system in the forest complex; essences and classifications of approaches to pricing are considered and analyzed. The purpose of the study is to analyze the currently existing pricing system efficiency in the forest industry, improve the system for assessing forest stands using the rental approach when harvesting timber in a leased forested area. These are the main ideas of the research. Pricing is one of the most important components of the forest industry, since the role of resource price formation is not only to provide the enterprise with revenue, but should also contribute to the effective implementation of the state policy for the forest fund reproduction. This proves the need to develop a methodology that solves the issue of natural resources efficient use. A computational experiment on calculating the cost of producing round timber when renting forests for the purpose of harvesting timber makes it possible to identify rent that contributes to a more rational use of the forest fund. In the field of forestry, various approaches to pricing are used such as comparative, costly, profitable, systemic, mathematical and rental ones. Pricing in the forest industry implies the presence of three economic components necessary for the implementation of an effective state policy, namely the social component, reproduction and innovation. A computational experiment on calculating the cost of a standing crop on a forest plot located on the territory of the Yambatorsky district forestry of the Mari-Turek forestry in the Mari El Republic showed that the natural rent makes up 27,6 %, and taking into account the standard profit, the rent totals 39,7 %. The relative value of the minimum payment rates for standing crop for the trial forest area is 1,5 % of the market value of the assortments. The result of the study is to develop measures aimed at improving the efficiency of the pricing system. The proposed approach to calculating the cost of standing crop as a whole will allow taking into account the main rent-forming factors and increasing the efficiency of forest management from the point of view of the state policy, as well as establishing equal economic opportunities for forest users.

Published: October 2023

Background: High milk production and excellent fertility is a dream of livestock owners.The major reproductive disorders which lead to decrease the productivity and reproductive ability of farm animals is postpartum anestrous.Recently, kisspeptin was reported as game changer in the animal reproduction. Kisspeptin increases the number of follicles at wave emergence, oestrus response rate and duration of oestrus. Thus, indicating its potentiality for induction of oestrus in anestrous animals. Methods: The present study was conducted to compare the efficacy of Ovsynch and kisspeptin protocol and need of fortification for treatment of postpartum anestrous.Fifty postpartum anestrous cows were selected. The animals were divided into four treatment groups (10 cows in each) and treated with Ovsynch (Group I), Ovsynch fortified with mineral mixture (MM) and bypass fat (BPF) (Group II), kisspeptin (Group III) and kisspeptin fortified with MM +BPF (Group IV). The remaining 10 cows served as control (Group V). The oestrus response was recorded on the basis of behavioral signs, physical signs and clinico-gynaecological changes. The blood was collected following treatment for hormonal estimation. The pregnancy was confirmed on day 45 post AI using ultrasound. Result: The oestrusresponse was pronounced in Ovsynch as compared to kisspeptin groups. Further, fortification has enhanced the response. The serum oestrogen concentration increased following treatment and was significantly high on day of onset of oestruswith highest concentration in group II. The results indicate Ovsynchdistinguishly succeeded in addressing postpartum anestrus with fortification enhances fertility response.However, kisspeptin also emerged as a potent candidate for the resumption of cyclicity.

Background: Semen cryopreservation induces alterations in spermatozoa and changes in the plasma membrane, limiting the acrosome reaction and fertilizing ability. The research aim was to study the sperm capacitation indicators and acrosome reaction capacity in rooster semen, comparing fresh semen and post-thaw semen. Methods: Fifty ejaculates were obtained from five roosters through dorsal-ventral massage. Semen was diluted and preserved fresh or cryopreserved in Beltsville Poultry Semen Extender. In both groups of preserved semen, basic seminal parameters, capacitation and acrosome reaction were assessed. The latter were evaluated both with and without a perivitelline layer as the acrosome reaction inducer, using chlortetracycline staining. Result: The results revealed a higher percentage of sperm progressive motility in fresh semen (85.2±1.5%) compared with thawed semen (44.8±1.7%; P less than 0.05). The percentages were similar when comparing sperm with an acrosome reaction in fresh semen (10.6±1.1%) to sperm incubated without a perivitelline layer (13.2±1.7%; P greater than 0.05). However, when incubated with a perivitelline layer for 40 minutes, fresh semen spermatozoa exhibited a higher percentage of acrosome reaction (59.2±2.1%) compared with thawed semen incubated with a perivitelline layer (40.6±2.3%; P less than 0.05).

Background: Groundnut (Arachis hypogaea L.) holds significant importance as a staple food legume and a key economic crop, serving as a valuable source of edible oil and protein in India. However, its full yield potential is often hampered by excessive vegetative growth, which leads to suboptimal yields. With this background, a field experiment was conducted at the Perunthalaivar Kamaraj Krishi Vigyan Kendra in Puducherry during 2020 and 2021. The objective was to investigate the influence of different concentrations and timing of paclobutrazol (PBZ) application on the growth and yield of groundnut. Methods: The experiment was laid out in a split-plot design with three replications, six main plot treatments (Including PBZ concentrations of 25, 50, 100, 150, 200 ppm and a control) and three sub-plot treatments (Involving single sprays at 30 days after emergence (DAE), single sprays at 50 DAE and double sprays at 30 and 50 DAE). Result: The results revealed that the application of paclobutrazol at different concentrations had a positive effect on reducing plant height during the later stages of growth, particularly when a double spray was applied at 30 and 50 DAE. Notably, the application of paclobutrazol at a concentration of 200 ppm in groundnut cultivation proved to be economically viable, resulting 29% increase in pod yield compared to the control group. Specifically, PBZ at 200 ppm, with a double spray, significantly boosted the total pod yield to 2724 kg ha-1. Furthermore, the correlation and regression analyses indicated a positive relationship between growth and yield.

Considering both the ecological niches of fungi and the different benefits they provide to humans, it is expected that students have a high level of scientific knowledge about living things in this kingdom. In the study, it was aimed to examine the learning of secondary school students about living things in the fungi kingdom. The research, which was carried out as a case study, was carried out with 52 secondary school students studying in the Central Anatolia Region of Türkiye in the 2022-2023 academic years. In the research, it was determined that the students had misconceptions and lack of knowledge about the classification of living things in the fungi kingdom, their diet, ecological functions and their effects on human life. The students stated that fungi take place in the world of plants, feed by photosynthesis and are used in making yogurt. According to these results, it is recommended to conduct studies on textbooks, teaching methods and teachers that cause students' misconceptions about living things in the fungi kingdom.

Terrorism is currently one of the greatest global challenges, which covers a very wide spectrum of threats to contemporary societies and the world. It is the subject of many debates, conferences and media broadcasts focused on achieving various goals, unfortunately not always informative. These threats have different typologies, causes, distribution and centers of influence. The dangers associated with it evolve and are a permanent state, hence the possibility of completely eliminating the occurrence of such forms of threats is practically impossible, and assuming even hypothetically such scenarios in theory is rightly treated as fiction. Therefore, terrorism has become a permanent element of reality, very visible in the media, socially, economically and politically, with which you have to learn to live with, be able to interpret the environment (symptoms, disturbing signals), protect yourself and others and react appropriately to the situation. Be aware not only of the potential of threats that may occur in your own country, but also in other countries, especially neighboring countries, know where to look for the necessary information and have the habit of preparing for trips abroad, especially when they relate to a different cultural zone. What is necessary to develop this type of behavior in the social space – on the one hand, the activity of government institutions and international organizations aimed at minimizing threats, on the other hand, the preparation and implementation of the concept of a permanent process of building, supporting and developing a safety culture addressed to various social groups and categories, mainly through system-based education, which will provide a wide range of competences in the field of knowledge (and the need to constantly update it) and practical skills (applying theory in practice in a manner appropriate to the situation). The aim of the article is to present the role of the goals and initiatives of the Terrorist Prevention Center of the Internal Security Agency as an institution responsible for the prevention and education of society in the area of terrorist threats.

Exploring Educators’ Perception on learner’s right affecting discipline in Secondry Schools
Authors: Mahaye Ngogi Emmanuel
Published: October 2023

The aim of this study was to investigate educator’s perceptions of how learners’ rights to safety affect disciplinary procedures in secondary schools in the Umbumbulu Circuit of KwaZulu-Natal. The paper adopted a qualitative approach, where semi-structured interviews were used to collect data from 10 purposively selected educators. The thematic analysis technique was employed to analyse the data. The main findings of the study indicated that educators had their own perceptions of how learners’ rights to safety affect the way they attend to disciplinary issues when a learner has transgressed. The educators’ perceptions of learners’ rights to safety affect disciplinary procedures for many reasons, including poor understanding of relevant education laws and policies. The results also showed that teachers think that the legislation guiding teaching and learning, as well as disciplinary procedures, are marred with contradictions, which make discipline management not only difficult, but also exposes both the learners and the educators to unsafe environments. The study also indicated that the teachers are sensitive to learners’ rights to safety, resulting in restricted attention to learners who are guilty of an offence in the school. In light of these findings, it was recommended that there should be a mandatory continuous in-service workshop for the educators, on how learner discipline can be maintained.

Published: October 2023

Transportation is undergoing its most significant transformation since the inception of road transport. This transformation is fueled by concerns about climate change and technological advancements. Understanding the current situation in medium-sized cities across Europe is crucial to developing transportation concepts for urban areas within the EU. This study offers insights into the current state of urban mobility in post-communist countries and depicts the current spatial mobility in a medium-sized city. The aim of this study is to evaluate the influence of selected socioeconomic factors on the mobility of employees and students. This study, conducted in 2019, employed quantitative research methods, including a questionnaire survey. In total, 545 employees and students participated in the survey, representing a significant indicator of mobility in the city of Zlín. Data analysis was performed using nonparametric methods. The results indicate a relationship between respondents’ job classification, age group, transportation time, and choice of means of transport. These findings can be applied to countries with similar historical and cultural development backgrounds, such as Poland, Hungary, and Slovakia.

STUDY ON THE ESTIMATION OF SARS-CoV-2 VIRUS PATHOGENS’ TRANSMISSION PROBABILITIES FOR DIFFERENT PUBLIC BUS TRANSPORT SERVICE SCENARIOS
Authors: BURDZIK Rafał , SPEYBROECK Niko
Published: October 2023

The worldwide COVID-19 pandemic revealed societal challenges, with passenger transport rapidly experiencing the impacts of the virus and the evolution of the concept of safety in transport. Evaluating the likelihood of viral transmission within transportation systems may be a substantial challenge, considering the complex processes that influence the incidence of random transmission events. This paper introduces a method for determining the probability of pathogen transmission in public transport, focusing on the SARS-CoV-2 virus. The study draws on scenarios from the first and second waves of the COVID-19 pandemic in Poland, a period that was devastatingly marked by the lack of available vaccines. This study aims to add value to the scientific community by offering an estimation of the likelihood of SARS-CoV-2 transmission in public transport and a preliminary risk assessment for COVID-19 infection, considering the number of active, non-isolated COVID-19 cases in the Polish population. The potential of this approach was demonstrated through a comparison between two different categories of passenger transport in a city bus. Based on the presented case study and the calculated probability of pathogen transmission, it is estimated that the probability of SARS-CoV-2 infection during the second wave of the COVID-19 pandemic in Poland through the use of public transport was approximately 0.05%. Probability estimations based on elementary events, which can vary depending on the service category (for instance, the form of ticket purchase, availability of seating or standing places, or ticket inspection), can reveal even the smallest differences in the total likelihood of pathogen transmission. However, these minute individual variations significantly impact the total metrics calculated for daily users of public transport. For effective monitoring of potential epidemic threats and for designing suitable interventions and restrictions to lower the risk of future pandemics, it may be necessary to understand the role that transportation systems, particularly public transport systems, play in the spread of pathogens.
Pengaturan Jabatan Rangkap Anggota Direksi dan Dewan Komisaris BUMN: Perbandingan Indonesia dengan Amerika Serikat

Published: October 2023

This research aims to identify the comparison between the arrangements for interlocking directorates or dual positions of Directors and Commissioners of BUMN in Indonesia and the United States. This is because the two countries have different arrangements and approaches to proof. The problem formulation in this research is how interlocking directorates are regulated in the United States, and how the interlocking directorate arrangements for Directors and Commissioners of BUMN in Indonesia compare with the United States. This is normative legal research with statutory, conceptual, and comparative approaches. The results of this research are, first, the legal basis for interlocking directorates in America is regulated in the Clayton Act Section 8, while in Indonesia is regulated in several sectoral laws and implementing regulations. Second, the body authorized to monitor anti-competition in the United States is the FTC, while in Indonesia it is the Supervisory Board for Business Competition (Komisi Pengawas Persaingan Usaha, KPPU). Third, the imposition of sanctions in the United States is civil penalties, while in Indonesia there are administrative sanctions, principal penalties and additional penalties. Fourth, the approach used in the United States is illegal per se, whereas in Indonesia it is the rule of reason. Even though in the Business Competition Law the approach used in multiple positions is the rule of reason, it does not rule out the possibility that the business competition approach can be carried out using an illegal per se approach.

Published: October 2023

Organic Medium Enclosed Trough (OMET) is a new non-drainable growing technique. The study envisioned to investigate the interactive effects of OMET and Amaranth species vari-ation on some growth attributes, bioactive compounds and nutrients. Three Amaranth species: A. caudatus, A. cruentus and A. tricolor were grown in an OMET and non-OMET growing conditions. Growth attributes, irrigation water, bioactive compounds and nutri-ents were determined. Non-OMET and A. cruentus showed the highest total phenolics and flavonols followed by A. caudatus and A. tricolor, whilst tannins were predominant in A. caudatus followed by A. cruentus and A. tricolor. The use of unsupervised PCA showed major metabolic variation based on Amaranth species and the use of supervised OPLS-DA showed clear metabolic variation based on OMET and non-OMET. OMET and A. cruentus showed the highest plant height, stem diameter, biomass, and some nutrients (%protein, Ca, P, Cu, Se, Zn), followed by A. caudatus based only on growth and biomass, and A. tricol-or based only on some nutrients (Mg, K, Mn, and Fe). The use OMET system on A. cruentus and A. tricolor can be recommended to mitigate climate change effects on nutritional com-position using low irrigation water.
