Koordynacja transakcji między grupami producentów rolnych a przemysłem spożywczym. Studium przypadku
Authors: Malchar-Michalska Dominika
Published: October 2024

Celem artykułu jest odpowiedź na pytanie, czy istniejące sposoby koordynacji transakcji (w szczególności kontrakty/powiązania umowne) między grupami producentów owoców i warzyw a przemysłem spożywczym zmniejszają ryzyko produkcyjne i cenowe tych pierwszych podmiotów. W artykule wykorzystano holistyczne podejście do kontraktów, w którym analiza skoncentrowana jest na trzech sferach: motywacji, koordynacji oraz kosztach transakcyjnych, co w efekcie pozwala określić, czy występuje tzw. zintegrowana korzyść z kontraktu. W artykule skupiono się na koordynacji, uwzględniając koordynację produkcji oraz ryzyko (ograniczenie i podział ryzyka między stronami kontraktu). Tłem teoretycznym dla prowadzonych rozważań i badań była teoria kontraktów. W artykule podjęto próbę identyfikacji kanałów dystrybucji między grupami producentów owoców i warzyw a przemysłem spożywczym. Do realizacji celu pracy wykorzystano metodę wielokrotnego studium przypadku. Dane pozyskano metodą wywiadu pogłębionego z przedstawicielami wybranych grup producentów owoców i warzyw zlokalizowanych na terenie województwa dolnośląskiego. Zakres czasowy analizy obejmował rok 2013. W badanym okresie sprzedaż owoców odbywała się na rynku kasowym. Powiązania umowne (umowy na dostawę lub umowy kontraktacji) występowały głównie przy sprzedaży warzyw. W analizowanych powiązaniach umownych nie można było stwierdzić, że dzięki nim w badanych jednostkach nastąpiła znacząca poprawa koordynacji produkcji i ryzyka.
Produkcyjne wykorzystanie zasobów ziemi rolnej w gospodarstwach rolnych z uwzględnieniem ich form prawno-organizacyjnych
Authors: Dzun Wodzimierz
Published: October 2024

W Polsce po 1989 roku widoczna jest tendencja znacznie szybszego zmniejszania się powierzchni gruntów rolnych w użytkowaniu gospodarstw rolnych niż powierzchni gruntów rolnych ogółem. W latach 1990–2010 liczba gospodarstw zmniejszyła się z 3 834,0 tys. do 2 277,62 tys. (o ponad 1 566 tys.), a powierzchnia gruntów rolnych w ich użytkowaniu z 18,54 mln do 15,5 mln ha (o ponad 3 mln ha). W rezultacie narasta bardzo szybko obszar użytków rolnych niebędących w użytkowaniu gospodarstw rolnych. Jeśli w 1990 roku obszar ten wynosił około 0,27 mln ha, to w 2002 roku już 1,56 mln ha, w 2010 roku – 2,59 mln ha, a w 2013 roku – 3,42 mln ha. W rezultacie, mimo bardzo niewielkiego wzrostu liczby ludności, powierzchnia gruntów rolnych użytkowanych przez gospodarstwa rolne w przeliczeniu na jednego mieszkańca zmniejszyła się odpowiednio z 0,49 do 0,4 ha i 0,38 ha. W wyżej przedstawionej sytuacji, przy tym w warunkach narastającego zapotrzebowania na żywność, bardzo dużego znaczenia nabiera nie tylko problem zahamowania odpływu gruntów rolnych poza gospodarstwa rolne, lecz także problem efektywnego produkcyjnego wykorzystania gruntów rolnych będących w użytkowaniu gospodarstw rolnych. W przedkładanym opracowaniu przedstawiono analizę wpływu formy prawno-organizacyjnej gospodarstw rolnych na skalę produkcyjnego wykorzystania gruntów rolnych będących w ich użytkowaniu. Analizie poddano zmiany w wykorzystaniu gruntów rolnych w latach 2002–2010 na tle lat poprzednich. Podstawą opracowania są dane Powszechnych Spisów Rolnych z lat 1996, 2002 i 2010 oraz literatura przedmiotu badań. Przedstawiono także podstawowe tendencje zmian w skali produkcyjnego wykorzystania użytków rolnych w latach 2010–2013 na podstawie reprezentacyjnego badania gospodarstw rolnych z 2013 roku.
Ochrona produktów regionalnych i tradycyjnych w Unii Europejskiej. Wybrane zagadnienia ekonomiczne i prawne
Authors: Baer-Nawrocka Agnieszka , Suchoń Aneta
Published: October 2024

Artykuł traktuje o aktualnej sytuacji na rynku produktów chronionych w Unii Europejskiej z uwzględnieniem regulacji prawnych w zakresie tworzenia i funkcjonowania grup podmiotów (producentów i przetwórców) związanych z tymi produktami w świetle przepisów unijnych. Analizie poddano wartość sprzedaży i liczbę zarejestrowanych produktów chronionych w UE oraz wybrane zagadnienia związane z omawianymi produktami w Polsce. W dalszej części przedstawiono regulacje prawne we Francji i Włoszech dotyczące grup oraz przykłady tych działających przede wszystkim w formie spółdzielni. We wnioskach wysunięto postulat wprowadzenia dodatkowych instrumentów zachęcających do tworzenia grup w Polsce, co jest zgodne z wytycznymi ustawodawcy unijnego oraz przyczyni się do zwiększenia znaczenia polskich produktów chronionych zarówno na rynku krajowym, jak też unijnym. Zasadne jest także wprowadzenie do ustawodawstwa polskiego szerszej definicji działalności rolniczej. Umożliwia ona producentom rolnym bez zbędnych formalności uczestniczyć w kolejnej fazie łańcucha żywnościowego, czyli przetwórstwie produktów chronionych.

Authors: Adamowicz Mieczysław
Published: October 2024

Zadanie podsumowania międzynarodowej konferencji naukowej „Rolnictwo, gospodarka żywnościowa, obszary wiejskie – 10 lat w Unii Europejskiej”, jaka została zorganizowana w SGGW 11 kwietnia 2014 roku, jest zadaniem niezwykle trudnym ze względu na jej rangę merytoryczną, zaangażowanie kluczowych organizatorów, pozycję i geograficzne pochodzenie uczestników oraz wielowątkowość tematyczną wystąpień. Wszystko to, a także niemożliwość uczestniczenia w obradach wszystkich równoległych sesji oraz selektywność uwagi, sprawia, że nie można mojego wystąpienia traktować jako w pełni obiektywnego podsumowania wyników konferencji, a jedynie jako garść refleksji i wniosków uczestnika, który starał się uważnie przysłuchiwać obradom plenarnym i krótkim sprawozdaniom z sesji równoległych.

Минимальный месячный приток воды к Колымскому каскаду ГЭС в летне-осенний период в эпоху глобального потепления
Authors: М.В. Ушаков
Published: October 2024

Цель работы – определить, какие климатические изменения будут соответствовать минимальным месячным притокам воды к каскаду ГЭС на р. Колыме в летне-осенний период к концу XXI века. Многолетние ряды притока воды к водохранилищам содержат статистически значимые положительные тренды. На основе корреляционных связей скользящих 30-летних средних величин притока и среднегодовой температуры воздуха получены формулы, по которым были рассчитаны экстремально низкие значения месячного притока на конец нынешнего века при различных сценариях потепления климата. Так, при повышении среднегодовой температуры воздуха на 2ºC минимальные месячные значения притока вероятностью превышения 99 % увеличатся на 23,8–39,2%. Информация о такой трансформации режима минимального стока облегчит управление каскадом ГЭС в экстремально маловодные годы.
Long-term Outcome of a Chihuahua With Idiopathic Syndrome of Inappropriate Antidiuretic Hormone Secretion
Authors: Adin Darcy B. , Levinzon Ilana , Harris Autumn N.
Published: October 2024

An approximately 3 yr old female Chihuahua was presented for evaluation of polyuria and polydipsia noted by the owner after adoption. Serum biochemistry and urinalysis revealed hyponatremia, hypochloremia, hypo-osmolality, and normal fractional excretion of sodium. Serum antidiuretic hormone concentration was 5.54 pg/mL and serum copeptin concentration was 135.40 pg/mL. The antidiuretic hormone value was above the reported range for healthy dogs and was considered inappropriate in light of serum osmolality. Idiopathic syndrome of inappropriate antidiuretic hormone secretion was considered the most likely diagnosis after excluding other potential causes, such as diuretic use, renal disease, adrenal disease, and thyroid dysfunction. The dog remains clinically well 2 yr after diagnosis without specific treatment other than minimal dietary salt supplementation. This case is unique because of the absence of systemic or neurologic signs, good long-term outcome without treatment, and use of novel diagnostic testing.
Treatment of Nonsocial Environmental Fear in a Service Dog Using Fluoxetine and Behavior Modification
Authors: Khan Michael Zafar , Bennett Sara Lynn
Published: October 2024

Training and maintaining a service dog requires extensive time and financial resources. The emotional bond between service dogs and their handlers poses unique challenges when dogs develop behavioral issues. We present a case of an otherwise healthy adult service dog exhibiting acute environmental fears, hindering her job performance. The dog’s fear responses escalated in various settings, including school and home environments. Diagnostic evaluation ruled out medical pathology, leading to a diagnosis of nonsocial environmental fear and generalized anxiety. A multimodal treatment approach involving environmental management, antidepressant medication (fluoxetine), and behavior modification was implemented. Desensitization and counterconditioning protocols targeted specific triggers, such as shiny floors and elevators. Eight weeks after treatment initiation, the dog showed improvement, enabling a modified behavior treatment plan to be implemented as she gradually returned to work with reduced fear responses. Follow-up revealed sustained progress with additional dosage adjustment of fluoxetine.
2024 AAHA Community Care Guidelines for Small Animal Practice
Authors: Greenberg Mike , McCants Donita , Alvarez Elizabeth , Berliner Elizabeth , Blackwell Michael , McCobb Emily , Price Tierra , Robertson Jyothi , Stambolis Melina
Published: October 2024

Community care is a creative way of thinking about health care that mobilizes resources within a community and consists of four core principles: recognition of the urgency of access-to-care for the veterinary profession, collaboration within community networks, family-centered health care, and redefining the gold standard of care. The AAHA Community Care Guidelines for Small Animal Practice offer strategies to help busy veterinary practitioners increase access to care within their practice and community by optimizing collaborative networks. While these guidelines do not claim to provide exhaustive solutions to access-to-care issues, they propose a starting point from which private practices can explore and implement workable solutions for their community and their practice. Broadening the scope of care to reach all people with pets requires multimodal, collaborative, and creative solutions both within and outside of the veterinary profession. These solutions can begin with greater communication and collaboration between private veterinary practices and nonprofit veterinary practices, with the goal of keeping pets in their homes with their loving families as much as reasonably possible.

A Study on the Prosecutor's Presupposition Strategies in Courtroom
Authors: Wang Yaqi
Published: October 2024

As technology improves by leaps and bounds, forensic linguistics, as a separate and interdisciplinary research field, has attracted the attention of a growing number of scholars. The purpose of courtroom discourse is clearer than that of everyday language. In a trial, all parties involved, whether judges, prosecutors, defense attorneys or defendants, are committed to achieving their stated goals through a variety of linguistic strategies and techniques. And presupposition itself is a highly purposeful linguistic strategy. As a result, judges, prosecutors and lawyers often use the technique of presupposition to obtain information in their own favor in court interrogations. From the perspective of forensic linguistics, this paper uses the theory of presuppositions, including semantic and pragmatic presuppositions, to provide a qualitative analysis of real cases in courtroom. The results show that the application of presuppositions in court allows the prosecutor to control the defendant's answers to a certain extent and has a positive effect in their own favour.
Problems and Solution Strategies of Teacher-Child Interaction in Kindergarten Role Games
Authors: Zhong Guolong , Xie Yuyi , Wang Mingxi , He Maohui
Published: October 2024

In kindergarten education, interaction and communication between teachers and young children constitute the core means and realization of educational activities. It is found that the interaction initiation in role play presents significant asymmetry, and young children are often in a passive position; at the same time, there is a relative lack of emotional communication in the game, and young children are difficult to fully experience the fun and emotional resonance of the game. In addition, teachers showed more negative emotions during the game. What's more, teachers' timing and choice of methods in guiding children's play are inappropriate. To address the above problems, this paper proposes corresponding improvement strategies. First, teachers should ensure children's autonomy in play; second, teachers should pay more attention to children's emotional performance and psychological needs in play; at the same time, teachers should endeavor to create a harmonious and enjoyable atmosphere for teacher-child interactions; and lastly teachers should provide targeted guidance at the right time.

Authors: Chen Zijian , Song Shengyuan , Li Baotian , Yang Ze , Ma Muye
Published: October 2024

Utilizing the FLO-2D software, the motion processes of debris flows in Donghaolitaogao under 20-year, 50-year, and 100-year return periods of rainfall are analyzed, revealing that as the rainfall return period increases, the debris flow velocity, accumulation depth, and accumulation area all significantly expand. Specifically, under the 20-year, 50-year, and 100-year rainfall conditions, the maximum debris flow velocities are 1.85 m/s, 1.95 m/s, and 1.99 m/s, respectively, while the maximum accumulation depths are 1.31 m, 1.33 m, and 1.35 m, and the total accumulation areas are 27,267.8 m2, 31,500.6 m2, and 33,901.3 m2, respectively. Using the depth of debris flow and the product of debris flow depth and velocity as evaluation indicators, the debris flow hazard assessment indicates that the Donghaolitaogao debris flow is primarily characterized by low- and medium-risk areas, with high-risk areas scattered sporadically along the central part of the channel. Moreover, as the rainfall return period increases, the area of high-risk zones continues to expand, gradually accounting for a larger proportion of the total hazard zone.

Quality of wood chips produced for energy purposes in the southeast region of Paraná. To characterize and monitor the moisture content of the energy biomass used by a food industry in southwestern Paraná-Brazil, the materials of five different providers were analyzed, four were from Eucalyptus spp. and one from Pinus sp. The chips were characterized according to the moisture content on a wet basis, apparent density, calorific value and immediate chemical analysis was performed. With the collected data, calibration curves were generated to adjust the moisture content measurement equipment, MUG M75, used by the company. The calibration of the M75 was made based on the linear regression model, and all chips presented an adequate calibration curve with a coefficient of determination (R²) above 0.9. The chips had a moisture content of 35 to 45% in the humid base. The highest value of apparent density was 207.67 kg.m³. The superior calorific value was statistically equal for all materials, with an average of 4,384.4 kcal/kg. Regarding the immediate chemical analysis, volatiles were between 80 and 84%, for fixed carbon the highest value obtained was 19.16%. The studied chips had low ash contents, with a general average of 0.59%. All calibration curves showed high accuracy (> 90%), showing that the method used can replace oven drying after the recipe is calibrated for suppliers.
Cauchy discretization method for solve fractional linear optimal control problems
Authors: Aliane Mohamed , Moussouni Nacima
Published: October 2024

This paper presents a numerical scheme designed for solving fractional linear optimal control problems (FLOCPs) governed by Caputo fractional derivatives (CFDs) of order 0<α≤1. The method transforms the original fractional control problem into an equivalent linear programming problem (LPP), enabling a more straightforward solution process. To evaluate the performance and accuracy of this approach, several numerical experiments were conducted using MATLAB. These experiments highlight the method’s computational efficiency and its simplicity in terms of implementation. The proposed approach offers accurate results, particularly in scenarios where traditional methods may fall short due to the complexities introduced by fractional derivatives. A detailed numerical example is presented to further illustrate the method’s effectiveness in addressing FLOCPs. The outcomes suggest that this approach is not only practical but also provides valuable insights for researchers dealing with fractional calculus in optimal control theory. This contribution is expected to be beneficial for applications in engineering and the physical sciences, where fractional-order systems play a significant role.

Authors: Said Hakim Ait , Laifaoui Abdelkrim , Aissou Massinissa , Nouri Hamou
Published: October 2024

In this paper, our attention has been focused on the effect of the presence of dust particles on the characteristics of the corona discharge in an ESP electrostatic precipitator in wires to plate configuration. Different parameters are taken into account, in particular the influence of the polarity, of the source of continuous electric excitation, the number of active electrodes and the dimensions of the particles of the dust. The dust used is recovered in the chimney of a cement plant is sieved to have different particle sizes 80,250 and 500μm. Dust particles pass through the inter-electrode space. By corona effect, there will be an ionization of the gas around the wire, and creation of ions and electrons. The latter bombard the dust that is charged with electricity and are then attracted to the surface of the plates under the effect of the electric field. Dust is deposited on the plate electrodes. A model in the laboratory was used for the measurement of the discharge current and to plot the I-V characteristic as a function of the number of active electrodes in absence and in the presence of different dimensions of the particles of the dust particles.
The First Mean Value Theorem of integral in Perplex Plane
Authors: Qin Hao , Wang Mingda
Published: October 2024

Perplex numbers are an extension of the real numbers, consisting of pairs of real numbers that form a commutative ring. This article considers the partial order structure of perplex numbers and discusses the concept of perplex interval. Based on the definition of integration of perplex functions of perplex variable, this article we investigate the first mean value theorem of integral in perplex plane which can significantly enrich the mathematical toolbox by providing essential methods for estimating and approximating perplex number functions. It also simplifies the solution of complex integral problems involving perplex numbers and fosters theoretical extensions by exploring the behavior of perplex number functions under various conditions. This, in turn, promotes the development of perplex calculus, enhancing the overall theoretical and practical framework of perplex number analysis. In physics, particularly in relativity, studying the first mean value theorem for perplex numbers can provide more precise methods for describing and estimating physical quantities, enhancing the application of hyperbolic numbers in these fields.

Optimizing Short and Long Term Investment Returns Using Multi-Armed Slot Machine Algorithms
Authors: Liu Qiaojia
Published: October 2024

This study focuses on comparing the effectiveness of UCB, Thompson sampling and Epsilon-Greedy algorithms in multi-armed slot machine algorithms for short-term and long-term investment return optimization in financial markets. This analysis examines stock performance data from Tesla, General Motors, and Ford over specific periods: five years of weekly data (2019-2024) and six months of daily data (February to August 2024). From the results, it is shown that for long-term investments, Over the five-year period, Thompson Sampling outperformed UCB and Epsilon-Greedy algorithms in terms of stability and overall return, demonstrating a consistent upward trend with fewer fluctuations. For short-term investments, although the UCB algorithm performs similarly to the Thompson sampling algorithm, the returns in the UCB algorithm grow progressively slower as the timeline is lengthened. In the six-month daily data analysis, the Epsilon-Greedy algorithm excelled in capturing short-term gains due to its aggressive exploration mechanism, though it also showed higher volatility in response to market fluctuations, and the algorithm should be chosen to be able to keep up with the fluctuations in the stock market in real time, and the investor should take into account the cost of time as well as changes in the market in order to formulate an optimal investment strategy.The findings of this study will provide a practical type of approach to investors when developing investment strategies. Future research will explore other classes of new algorithms and consider more market factors so that they can be better adapted to the complex investment environment in the future.

Advanced MiniMax Optimality Strategy in Bandit Problems
Authors: Zhang Sai
Published: October 2024

Nowadays, with the development of the Internet, recommending personalized information for every user becomes economically valuable. How to properly recommend to users the content they prefer is important. Mostly, bandit strategies are useful for this problem. As one of the most time-saving algorithms, Minimax Optimal Strategy (MOSS) performs well in most data sets. However, the traditional MOSS algorithm applies a conservative strategy in order to minimize the cumulative regrets in the worst situations. This strategy will over-explore the bandit models and spend too much time exploring every arm at the initial stage. This means the MOSS strategy cannot fully take advantage of the known information and then the accuracy and efficiency will be lower. In real life, people have a lot of Internet information to look through and they will not stay on one website or one advertisement for a long time. So, designing an efficient algorithm that performs well in all situations and can make good use of the known knowledge to do quick exploitation becomes so important. Therefore, this research aims to develop an advanced MOSS algorithm that can properly explore each of the bandit arms and improve the performance of the exploitation phase. By achieving this goal, this research adds an enhancement factor on the confidence bound part to speed up the exploration process. The research bases on the MovieLens data set and the data set is divided into 18 categories (arms) according to its genre attribute. Then apply this new advanced MOSS strategy to the designed data set and compare its performance with normal MOSS and UCB algorithms. Results display that the advanced MOSS strategys selection provides higher total rewards and lower average cumulative regrets than others with the advantage of time-saving. This shows the improvement of the advanced MOSS strategy in balancing the exploitation and exploration phases.

Published: October 2024

Economic empowerment is one way to change people's lives for the better. Pantai Labu sub-district is known as a coastal area that has the potential for abundant marine catches.  This study aims to evaluate the effectiveness of the product diversification-based fishermen empowerment program by using the maqashid sharia perspective as an analytical framework. This research was conducted in three fishing villages in Pantai Labu Sub-district, by identifying the potential product diversification that can be produced from marine products. The research method used was a qualitative case study with a descriptive analysis approach. Data collection was carried out through in-depth direct interviews. The results show that product diversification such as seafood processing and home industry development has had a positive impact on the income and food security of fishing communities. In addition, this empowerment also encourages the achievement of Maqasyid Sharia objectives, such as increased income that safeguards wealth (al-mal), increased skills that support the intellect (al-aql), and family welfare that supports offspring (an-nasl). However, despite its great potential, product diversification often faces various challenges in business development, such as capital constraints, limited market access, and lack of product innovation

The myopic not presbyopic eyes (−3.00 D) were overcorrected by −7 D with bitoric, spherical, rigid contact lenses, base curve = 8.00/7.65 mm, back-vertex-power = −10.00/−12.00 D, over-all diameter = 10.4 mm. The refractive compensation with the spectacle lens, back-vertex-power = +6.50 D (corneal-vertex-distance 12.0 mm), front-surface-power = +7.50 D, refractive index = 1.50, over-all diameter = 65 mm, centre thickness = 7.10 mm together with contact lens build a Galilean type telescope with a maximum of magnification power. Results. The magnification power of the telescope was Vs = 1.091, the magnification power of the spectacle lens was Ve = 1.037 and the related total magnification power was Vg = 1.131. The telescope increased the binocular distance vision acuity from 0.40− to 0.63 and the binocular near vision acuity from 0.32+ to 0.40+. Conclusion. The Galilei system described is suitable for improving visual acuity in the case of special visual impairments.

Purpose. This report documented the occurrence of globe subluxation (GSL) during the insertion of a scleral contact lens (SL) and described the management of two keratoconus patients, in need of a gas permeable contact lens prescription and experiencing GSL. Furthermore, an anatomical explanation for the occurrence of spontaneous GSL is attempted. Material and Methods. Two separate case reports of GSL were evaluated and described. In case 1, the patient experienced GSL secondary to insertion of a trial SL and in case 2 the patient had experienced multiple GSLs secondary to Grave’s disease. Different management strategies were taken to help to provide functional vision for these patients. In case 1, the patient was fitted with a smaller corneal gas permeable lens to minimize lid manipulation needed to insert a lens and provide effective correction. In case 2, the patient’s existing Prosthetic Replacement of the Ocular Surface Ecosystem (PROSE) SL was designed to increase vertical lens steepness to tighten the lens fit and minimize the chance of losing the lens during wear. Results. With the help of the individually fitted contact lenses, it was possible to achieve visual rehabilitation in accordance with the patient’s specific needs. Conclusion. SL are fitted with increasing frequency and tend to require excessive lid manipulation, which may lead to GSL. This small case series demonstrated different lens design and selection maybe utilized to minimize the occurrence of GSL. The superior septum orbitale is perforated several times across the width of the upper lid by the aponeurosis of the levator. This structural arrangement weakens the superior septum orbitale and, postulated here, predisposes the eye to GSL by a herniation primarily of the superior septum orbitale.

This study employed a qualitative methodology through phenomenological research design to collect data via spoken testimonies and narratives. The participants of the study were middle-level managers of selected public HEIs in Oriental Mindoro for the academic year 2023-2024. Middle-level manager-respondents of the study will be limited to the Vice Presidents, Campus Executive Directors, Unit Directors, Deans, Coordinators and Program Chairs/Heads of the HEIs in Oriental Mindoro. The participants were chosen through purposive sampling. An interview guide was the study’s main instrument. Results showed that middle-level managers in HEIs face challenges such as resistance to change, budget constraints, resource allocation, and maintaining interdisciplinary collaboration and partnerships. Integrating strategic planning with quality management practices ensures long-term sustainability and continuous improvement through goal alignment, stakeholder involvement, regular plan updates, performance monitoring, and dedicated resources. To the quality assurance office, a process optimization program for middle-level managers may be conducted. The program should cover topics such as understanding and optimizing processes, continuous improvement, data analysis, project management, risk management, compliance, standardization, documentation, stakeholder management, collaboration, and cultural competence. Meanwhile, to the research and development office, a continuous improvement program for middle-level managers may be implemented. The program should cover topics such as prevention-based problem-solving, the Plan-Do-Check-Act (PDCA) cycle, information and training provision, and the goal of continual betterment. The program can be delivered through workshops, seminars, and on-the-job training.

Published: October 2024

Introduction: Rosai-Dorfman disease (RDD) is a benign, proliferative disease of non-Langerhans cell histiocytes typically involving lymphoid tissue. Pancreatic involvement is extremely rare.

Case Description: Our case is of a 53-year-old female who originally presented with vague epigastric abdominal pain. Magnetic resonance imaging (MRI) revealed a mass in the pancreatic body suspicious for malignancy. The patient successfully underwent a robotic-assisted subtotal pancreatectomy and splenectomy. The final pathology revealed sheets of foamy histiocytes with enlarged vesicular nuclei and nucleoli. Immunohistochemical testing was positive for S-100 protein and CD163 and negative for CD1a and ALK-1, establishing a diagnosis of pancreatic Rosai-Dorfman disease. Next generation sequencing was positive for an F53L variant mutation of the MAP2K1 gene.

Discussion: Overall, there is no uniform approach for RDD treatment, treatment is usually tailored to the individual’s clinical picture. Here we describe a novel technique of robotic-assisted resection of pancreatic Rosai-Dorfman disease.

Objective: In the current study, we aimed to ascertain the levels of heavy metals and radioactive elements in the ovarian follicular fluids of pregnant and non-pregnant Kyrgyz mares.
Materials and Methods: To this end, follicular fluids were obtained from 49 Kyrgyz mares aged 3–5 years. The mares were in various stages of pregnancy (Group 1, n = 27) or were non-pregnant (Group 2, n = 22). We measured the levels of cadmium (Cd), lead (Pb), mercury (Hg), antimony (Sb), cobalt (Co), potassium (K), uranium (U), nickel (Ni), and thorium (Th) in follicular fluids using atomic emission mass spectrometry. Subsequently, the data were statistically analyzed according to whether the mare was pregnant or not, the pregnancy stage, the presence or absence of the corpus luteum in the ovaries, the corpus luteum’s diameter if present, and the presence or absence and diameter of follicles.
Results: We found that K levels were higher in non-pregnant mares (0.00564 ± 0.000590 ppm, p = 0.009). Furthermore, Ni (0.01033 ± 0.001880 ppm, p = 0.07) and K (0.00563 ± 0.000498 ppm, p = 0.026) levels were higher in mares with a follicle diameter of 1–3 cm. However, these results did not change according to the month of pregnancy, number of follicles, presence or absence of the corpus luteum in the ovaries, number of corpora lutea, and their diameters.
Conclusion: Thus, we concluded that heavy metal and radioactive element levels in the ovarian follicular fluids of Kyrgyz mares do not significantly change with pregnancy status, and there are limited detrimental effects of pollution on the follicular fluids.

Reverse zoonosis or zooanthroponosis is the transfer of pathogens from humans to animals. Although less studied than zoonotic diseases, this phenomenon poses significant risks to both animal and public health. The increasing human-animal interactions driven by urbanization, globalization, and environmental changes have exacerbated the occurrence of reverse zoonosis. This review evaluated the global impact and transmission patterns of reverse zoonosis, highlighting the anthropogenic and intrinsic factors contributing to its emergence. The study performed a systematic review and included 91 scientific articles published from 2000 to 2022, covering viral, bacterial, parasitic, fungal, and protozoal reverse zoonoses. This study indicated that viral infections, particularly respiratory viruses such as severe acute respiratory syndrome coronavirus-2 and influenza, have the highest incidence of reverse zoonosis, followed by bacterial infections like tuberculosis and methicillin-resistant Staphylococcus aureus. The United States, India, and Hong Kong are among the most reported regions for reverse zoonotic events. Major risk factors identified include environmental degradation, climate change, antimicrobial resistance, and global wildlife trade. The review underscores the need for enhanced surveillance systems, interdisciplinary collaboration, and stringent regulations on wildlife trade and animal husbandry practices to mitigate the risks associated with reverse zoonosis. Understanding the dynamics of human-animal pathogen transmission is crucial for developing not only effective but also sustainable strategies to protect animal populations as well as public health from emerging infectious diseases.
