Comparison of Spiral Versus Lateral Plate Fixations in Treatment of Multiple Humeral Fractures: A Finite Element Analysis
Authors: Chen Ya , Ou Shuan-Ji , Yang Yang , Zhang Wei , Xia Chang-Liang , Xu Chang-Peng , Qi Yong
Published: January 2023

Open reduction internal fixation technique has been generally accepted for treatment of complex humeral fractures. Traditional proximal humeral locking plate design (PHILOS) have been reported in clinical or biomechanical researches, while presently the spiral plate design has been introduced improved biomechanical behavior over conventional designs. In order to objectively realize the multi-directional biomechanical performances and minimally invasive surgery for humeral plate designs, a current conceptual finite element analysis has been conducted with identical cross-sectional features for humeral plates. The conceptual lateral, and spiral humeral plate models were constructed for virtual reduction and fixation to the multiple fractures of the humerus. Mechanical load cases including axial compression, counterclockwise torsion and anterior bending have been applied for confirming the multi-directional structural stability and implant safety in biomechanical perspective. Results revealed that the lateral humeral plate model showed lower equivalent (von-Mises) stress under counterclockwise torsion, while the spiral humeral plate model performed greater rigidity and lower equivalent (von-Mises) stress under other loading cases. Four models represented similar structural stiffness under bending load. Under the different mechanical load cases, the spiral humeral plate model revealed comparable results with acceptable multi-directional biomechanical behavior. The concept of spiral humeral plate design is worth considering in practical application in clinics. Implant safety and stability should be further investigated by evidences in future mechanical tests and clinical observations.
Family life in urban public spaces: stretching the boundaries of sociological attention
Authors: May Vanessa
Published: January 2023

This article contributes to a reconceptualisation of the boundaries of sociological attention regarding where family is enacted. Despite being aware of the cultural contingency of the distinction that is drawn between the public and private spheres, family scholars in the Global North tend to study families as bounded units with an ‘inside’ and an ‘outside’, and as spatially centred in the home. I argue that there is a need to systematically explore how mundane interactions and activities in public settings are woven into family life. Furthermore, drawing from research into family life in cities, I make the case for conceptualising public spaces as aspects of and even as characters in family life, and ask how people realise their family capacities in these. I propose that keeping these different facets of family life in view both analytically and empirically could lead to a radical shake-up of sociological thinking about family.

Inter-organisatorische Data Governance: Vorschlag eines Rollenmodells für einen kooperativen Datenaustausch im Kontext von Logistik 4.0
Authors: Zimmermann Luis , Schäffer Thomas
Published: January 2023

Der Austausch von Daten über die eigenen Organisationsgrenzen hinweg ist ein wesentlicher Bestandteil der Digitalisierung und im Zuge von Logistik 4.0 unabdingbar. Wenngleich dieser kooperative Datenaustausch noch in den Kinderschuhen steckt, wird ihm großes Potenzial für Kooperationen von Organisationen zugesprochen. Jedoch birgt der inter-organisatorische Datenaustausch auch Herausforderungen hinsichtlich der Qualität der auszutauschenden Daten, welche auf die Koordinationsfähigkeit der Organisationen zurückzuführen ist. Um diesem Problem adäquat zu begegnen, braucht es neben einer internen auch eine nach außen gerichtete Data Governance, die die Verantwortlichkeiten und Aufgaben klar festlegt. Der vorliegende Beitrag widmet sich daher der Aufgabe, ein einheitliches Verständnis über inter-organisatorische Rollen und deren Aufgabenbereiche zu schaffen. Mittels Literaturanalyse, Experteninterviews und Fokusgruppe wird der aktuelle Stand der Wissenschaft und Praxis dargestellt und die Rollen bzw. Aufgaben speziell für die inter-organisatorische Kooperation herausgearbeitet. Das Ergebnis ist ein Rollenmodell für eine inter-organisatorische Data Governance mit den erweiterten Elementen: Data Space Coordinator, Data Space Board und Data Space Working Team. Dabei ist das inter-organisatorische Rollenmodell ist in einem virtuellen Datenraum eingebettet und zeigt die Integration zur intra-organisatorische Data Governance.
SIK3 and Wnk converge on Fray to regulate glial K+ buffering and seizure susceptibility
Authors: Lones Lorenzo , DiAntonio Aaron
Published: January 2023

Glial cells play a critical role in maintaining homeostatic ion concentration gradients. Salt-inducible kinase 3 (SIK3) regulates a gene expression program that controls K+ buffering in glia, and upregulation of this pathway suppresses seizure behavior in the eag, Shaker hyperexcitability mutant. Here we show that boosting the glial SIK3 K+ buffering pathway suppresses seizures in three additional molecularly diverse hyperexcitable mutants, highlighting the therapeutic potential of upregulating glial K+ buffering. We then explore additional mechanisms regulating glial K+ buffering. Fray, a transcriptional target of the SIK3 K+ buffering program, is a kinase that promotes K+ uptake by activating the Na+/K+/Cl- co-transporter, Ncc69. We show that the Wnk kinase phosphorylates Fray in Drosophila glia and that this activity is required to promote K+ buffering. This identifies Fray as a convergence point between the SIK3-dependent transcriptional program and Wnk-dependent post-translational regulation. Bypassing both regulatory mechanisms via overexpression of a constitutively active Fray in glia is sufficient to robustly suppress seizure behavior in multiple Drosophila models of hyperexcitability. Finally, we identify cortex glia as a critical cell type for regulation of seizure susceptibility, as boosting K+ buffering via expression of activated Fray exclusively in these cells is sufficient to suppress seizure behavior. These findings highlight Fray as a key convergence point for distinct K+ buffering regulatory mechanisms and cortex glia as an important locus for control of neuronal excitability.

Published: January 2023

Paracoccidioidomycosis (PCM) is a systemic mycosis endemic in Latin America, mostly in Brazil. The involvement of the gastrointestinal tract is uncommon and usually associated with the acute form. Recently, a cluster of acute PCM cases has been described in Rio de Janeiro, Brazil. We report a 42-year-old male, resident of Rio de Janeiro, presenting chronic diarrhea and abdominal pain in the past 3 years, previously diagnosed as Chron´s disease. When immunosuppressive therapy was prescribed, the patient evolved with worsening of the previous symptoms in addition to odynophagia, 20 kg-weight loss, disseminated skin lesions, diffuse lymphadenopathy and adrenal insufficiency. Histopathological and mycological examination of a skin lesion were compatible with PCM. Itraconazole was prescribed in high doses (400 mg/day). After seven months of treatment, the patient presented with acute abdominal pain which led to an emergent appendectomy, revealing the presence of the fungus. After 24 months, the patient reached clinical cure and recovered from adrenal insufficiency. We emphasize the importance of PCM as a differential diagnosis in patients with chronic diarrhea. The risk of fungal infections should be considered prior to initiating immunosupressive therapies, particularly in endemic areas.
Comparative protection of small ruminants against Mannheimia haemolytica infection by inactivated bacterin and toxoid vaccines
Authors: Bkiri Dounia , Elmejdoub Soufiane , Bamouh Zahra , Fassi Fihri Ouafaa , El-Harrak Mehdi
Published: January 2023

Background and Aim: Mannheimia haemolytica causes respiratory infection and mortality in sheep and goats, similar to the effects in cattle, which causes major economic damage. Regular vaccinations alongside good management practices remain the most efficient tools for controlling this disease. Indeed, vaccines against pasteurellosis are available, but results on their efficacy have varied. Therefore, this study aimed to evaluate the efficacy of three vaccines against mannheimiosis in small ruminants.

Materials and Methods: We evaluated three vaccines developed from a local field isolate based on the inactivated bacterium, its toxoid, and a mixture of bacterin/toxoid, which we then tested on sheep and goats. Selected criteria that were evaluated were safety, antibody response, and protection through a challenge. Post-vaccination monitoring was carried out by enzyme-linked immunosorbent assay. The evaluation was based on antibody responses to vaccination in sheep and goats for both bacteria and leukotoxin. Protection was assessed by clinical and lesion scores after the challenge of vaccinated goats with a pathogenic strain.

Results: The three tested vaccines were completely safe, did not cause any adverse reactions, and induced significant antibody titers in immunized animals. Following M. haemolytica challenge, unvaccinated goats showed clinical signs with lesions typical of the disease. Meanwhile, the best protection was obtained with the inactivated combined bacterin/toxoid vaccine.

Conclusion: This study highlighted the effectiveness of adding a bacterial toxoid in the vaccine as a promising solution for preventing mannheimiosis in small ruminants. Because of the worldwide distribution of M. haemolytica infection, general prophylaxis based on a combined inactivated vaccine could greatly benefit.

Modulation transfer function of the Stokes lens and its computer-controlled application for clinical optometry of astigmatism
Authors: Plekhanov Alexander
Published: January 2023

Astigmatism is a highly prevalent cylindrical refractive vision defect. The capability of the Stokes lens to compensate for astigmatism of a human eye was examined with a primary interest towards clinical optometry. A prototype of a computer-controlled apparatus, based on the Stokes lens principle, was designed and built with an objective to simplify clinical subjective refraction of astigmatism. Physical properties of the employed optical system were studied using modulation transfer function (MTF) as a metric. It was shown that the apparatus is capable of both compensating an arbitrary astigmatic defect and measuring its optical characteristics. The accuracy of the optometric measurements was evaluated. The proposed apparatus enables a novel method of optometry of astigmatism which relies on a patient’s feedback obtained through intuitive manipulation of a computer human interface device, such as a mouse, in a 2-dimensional X-Y plane, rather than verbal interaction. This two-dimensional input is then translated into a virtual 2-dimensional space of optical power and the orientation angle of the cylinder axis and provides a measurement of astigmatism of the eye.
Implementing Campus-level Programming: Pathways for Online Civic Engagement
Authors: McGowan-Kirsch Angela
Published: January 2023

In a year marked by social unrest and a global pandemic, the 2020 presidential election occurred within a context of polarization and incivility. An American Democracy Project (ADP) campus believed that two ways to offset these complications were teaching students how to maintain norms of civility and helping students gain political knowledge that positioned them to contribute to online political discussions. ADP used Web 2.0 tools, namely social media and a web conferencing platform, to host political civic engagement activities and to promote civil political participation. Written from the perspective of a campus ADP chair, this reflective essay draws upon (in)civility, undergraduate political engagement, and online political discourse bodies of literature to offer suggestions for experimenting with Web 2.0 tools as a way to encourage students’ political civic engagement. In doing so, educators learn techniques for helping students become civil, informed, and engaged citizens in a polarized era.
An Exploratory Study of the Relation between Cognitive Style and Metacognitive Monitoring in a Sample of Colombian University Students
Authors: Montoya Londoño Diana Marcela , Hederich Martinez Christian , Gutierrez de Blume Antonio P.
Published: January 2023

While research on metacognition and cognitive styles is robust for either field alone, few studies have broached the two together. In addition, no studies to date have examined finer-grained objectives related to specific aspects of metacognition such as monitoring skill and its relation to cognitive style. Thus, the present study investigated confidence, performance, and accuracy measures for three types of metacognitive judgments (prediction, concurrent and postdiction) and three different types of metacognitive questions—questions about the task, questions about the self, and questions at different moments (before, during, and after)—and how these are related to cognitive style (field dependent, intermediate, field independent) in a sample of 57 Colombian university students. Results revealed that there were differences in metacognitive monitoring accuracy and bias as a function of cognitive style, and that these findings were similar both between different moments and across metacognitive judgments. Regarding cognitive style, those with an intermediate or field independent cognitive style reported greater monitoring accuracy and less bias than individuals with a field dependent style. Implications for research, theory, and practice are discussed.

Published: January 2023

El abuso sexual es un estresor que incrementa el riesgo de distrés psicológico. El objetivo de la investigación fue cuantificar la asociación entre abuso sexual y distrés psicológico (estrés postraumático, depresión y riesgo suicida) en estudiantes adolescentes en Santa Marta, Colombia. Se diseñó un estudio transversal. Participaron 1.462 estudiantes entre 13 y 17 años (M = 15,98; DE = 0,83). El abuso sexual se indagó mediante un ítem único del Cuestionario de Victimización Juvenil y el distrés con la Escala Breve de Davidson para estrés postraumático, el Índice de Bienestar General y la escala de ideación suicida del Centro de Estudios Epidemiológicos y (WHO-5). La prevalencia de abuso sexual fue 17,37%; riesgo de estrés postraumático, 19,36%; riesgo de depresión, 7,05%; y alto riesgo suicida, 13,27%. La historia de abuso sexual se asoció a estrés postraumático (Ajustado OR = 2,41; IC 95% 1,77 - 3,28), depresión (AOR = 2,48; IC 95% 1,59-3,88), y riesgo suicida (AOR = 2,51; IC 95% 1,77 - 3,56). Se concluye que el abuso sexual es un estresor que incrementa significativamente el riesgo de distrés psicológicos en estudiantes adolescentes en Santa Marta, Colombia. Se necesitan estudios de cohorte para controlar posibles variables de confusión para estas asociaciones.

Published: January 2023

The article deals with the selection of methods for studying human muscle fatigue in the operator-joystick system. This paper discusses ways of measure potential from the muscles of a person. The applicability of the chosen method for evaluating the work of the research object is considered. This article provides an overview of methods for diagnosing parameters of muscle fatigue in the operator-joystick system. In natural conditions, the excitation and contraction of muscles are caused by nerve impulses coming to the muscle fibers from the nerve centers. Under experimental conditions, electrical stimulation is used to cause muscle contraction. A motor or central program is considered as a prepared set of basic motor commands, as well as a set of ready-made corrective routines that ensure the implementation of movement taking into account the current afferent signals and information coming from other parts of the central nervous system.
STRATEGY OF DIFFERENTIATED DEVELOPMENT OF SUBJECTS OF THE RUSSIAN FEDERATION AND ASSESSMENT OF THE REGIONS ECONOMY UNIQUENESS
Authors: Pravdina Natalya , Danilova Irina
Published: January 2023

The strategic goals of spatial development of the Russian Federation are focused on finding promising specializations and simulating the differentiated development of regions. One of the mechanisms for the formation of regional uniqueness and transformation of the structure of the economy in multidisciplinary regions is the mechanism of agglomeration as a simultaneous pro-cess of intra-industry diversification and industrial concentration of the economic activity of a single industry (MAR effects) and the process of territorial concentration of resources, industries, competencies, dynamizing intersectoral diversification of economic activity (Jacobs effects). The ratio in intensity and strength of MAR and Jacobs effects determines promising centers of growth and specialization of regions. The article is aimed at assessing the uniqueness and substantiating the differentiated development of single-industry regions from the standpoint of identifying MAR and Jacobs effects using the example of official statistics for four regions of the metallurgical profile: Lipetsk, Vologda, Chelyabinsk regions, and Krasnoyarsk Territory. The assessment of in-tegral indices, as characterizing the results of changes in the structure of the economy using the example of these effects, has made it possible to substantiate the spectrum of unique trajectories of sectoral development, which varies from a symmetric polycentric sectoral structure in the Li-petsk Region to the preservation of monocentricity in the Chelyabinsk Region. The developed methodology for assessing regional uniqueness and identifying areas of differentiated develop-ment can become the basis for the formation of a complex of differentiated measures of public administration and support.

In this regard, a correct assessment of this indicator is relevant from the standpoint of the wide-spread use of innovations in differentiated sectors of the economy. Based on the analysis of scientific publications, an overview of approaches to assessing in-novative activity is presented, the interpretation of this concept is analyzed. The author proposes theoretical approaches to the development and application of a platform approach to assessing innovative activity.
INNOVATIVE DEVELOPMENT OF THE COMPANY BASED ON OVERCOMING LIMITING ASSUMPTIONS
Authors: Kaplan Aleksey , Valchuk Viktor
Published: January 2023

The problem of ensuring sustainable innovative development of companies is considered, which is based on subjective assumptions about the state and dynamics of the internal and exter-nal environment, not corresponding to reality. As a result, a root conflict arises, which inevitably reduces the effectiveness and the pace of development. It is determined that each company has the ability to overcome the limiting assumptions about the correspondence of the applied management tools and the management decisions made to the properties of the internal and external environment. Typical models of management per-ceptions regarding the complexity of the system, the uncertainty of the environment and staff motivation are substantiated. The sequence of the paradigm shift in managerial thinking on the basis of a consistent and logical rejection of limiting assumptions for the conditions of innovative development of the company are reasoned. Practical examples of the development of management decisions for the innovative devel-opment of companies based on consistent rejection of limiting assumptions are presented. It is proved that the application of the stated methodology in practice provides for significant expan-sion of sales markets; reduction of the production cycle; improvement of the level of service; growth of motivation and productivity of employees.
ASSESSMENT OF THE VARIABILITY OF THE DEMAND AND SUPPLY OF PROFESSIONAL SKILLS IN RUSSIAN REGIONS
Authors: Karpushkina Anzhela , Lavrentyev Alexey
Published: January 2023

The article considers the variability of the demand and supply of professional skills in the context of the regions of the Russian Federation as an indicator of possible inconsistencies in the labor market – skills mismatch. The author's approach to assessing the demand and supply of professional skills involved calculating the coefficients of demand and supply variability, identifying groups of regions with their maximum values in terms of the levels of professional training, and subsequently assessing the possible imbalances within the selected groups using the coefficient of unemployment variability. The implementation of the author's approach made it possible to identify the groups of regions with coinciding maximum values of the variability of demand and supply by education levels (higher professional education, secondary vocational education, pre-vocational education), to reveal the absence of significant differences in the values of the indicators of supply and demand variability of each region, and to conclude that there is no connection between the maximum variability of supply and demand for skills and unemployment. Based on the results of the study, it was concluded that for the majority of Russian regions there are insignificant differences in the variability of supply and demand for professional skills, what indicates to the absence of serious imbalances in the labor market in the context of vocational education.
JUSTIFICATION OF THE SIGNIFICANCE OF TECHNOLOGICAL ENTREPRENEURSHIP FOR THE KAZAKHSTAN REPUBLIC INNOVATIVE DEVELOPMENT
Authors: Smailov Sergey , Podshivalova Mariya
Published: January 2023

Today technological development is recognized as one of the key factors in increasing the competitiveness of national economies. In this direction, an active scientific search is being carried out both to identify the significance of the technological entrepreneurship phenomenon for innovative ecosystems, and to develop effective mechanisms for its development. This article is the contribution of the authors to the solution of the first scientific problem. The review of the literature on the Republic of Kazakhstan innovative development showed that the existing works either do not cover the significance of technological entrepreneurship for the current stage of economic development, or the studies are focused only on certain aspects of innovative activity. Therefore, a study is required to assess the dynamics and current state of innovation activity in the country and the prospects for the technological entrepreneurship development. In accordance with this goal, official statistical data were collected for the Republic of Kazakhstan for the period 2010–2020, characterizing the level of innovative development of the economy in accordance with the Oslo Manual’s requirements. The compiled time series of data were analyzed through an assessment of the dynamics of changes and compared with similar data from the countries of the European Union. As a result, it was found that in terms of innovative development the Republic of Kazakhstan lags far behind the leading EU countries (Germany, France, Great Britain, Italy) and is at a similar level with such countries as Lithuania, Cyprus, and Malta. For each indicator of innovative activity, the significance of the development of technological entrepreneurship was substantiated from the point of view of realizing the economic and innovative potential of the Republic of Kazakhstan. The study results contribute to the understanding of the strategic opportunities for the development of innovative entrepreneurship in the Republic of Kazakhstan and can be considered both as an achieved result and as a reference point for future measures to stimulate technological innovation.
INFLUENCE OF THE LOAD FACTOR ON VEHICLES REPAIR COSTS
Authors: Goryaev Nikolay , Khabibullozoda Kh.
Published: January 2023

One of the significant items of variable costs in road transport are repair costs. As the age of the vehicles increases, repair costs increase. However, the impact of the load on repair costs has been poorly studied, so the task of studying such an impact is relevant. During the operation of trucks during the transportation of goods, contact parts are damaged, especially suspension parts, body connecting elements, rotating transmission parts, etc. These parts are repaired as needed. The main share of the costs associated with the repair of freight transport falls on their maintenance and repair. As a rule, the main reason for the need for repair is the extreme wear and failure of parts and assemblies of vehicles. In the theoretical study, the influence of the load factor on the repair costs of truck transport is considered. The study is based on the hypothesis of a power-law effect of the load on wear, which has been confirmed in related industries. The result of the study revealed the dependence of the influence of the load factor on repair costs. A graph of the dependence of repair costs on the load factor is constructed, which allows you to more accurately predict cost variables and make informed decisions on the use of rolling truck.
Planning of Conventional Air Emission Reduction Strategy from the Transportation, Domestic, and Solid Waste Sector in Salatiga City
Authors: Samadikun Budi Prasetyo , Hardyanti Nurandani , Wijayanti Dea , Sa'adah Zumrotus
Published: January 2023

In 2020 Salatiga City has a population of 192,322 people with a population growth rate of 1.18%. The increase in population causes an increase in consumption needs, waste generation, and the number of vehicles due to increased population mobility. The purpose of this plan is to take an inventory of conventional air emissions in the transportation, domestic, and waste sectors and to plan strategies to reduce conventional air emissions in Salatiga City. The transportation sector emissions inventory is calculated using the Tier 2 method, while the domestic and solid waste sectors are calculated by multiplying activity data by emission factors. In the calculation of the capacity, the box model method is used and the SWOT analysis is used to determine the emission control strategy. The results of the inventory of conventional air emissions in the transportation sector for SOx are 121.06 tons/year, NOx is 2,615.51 tons/year, CO is 18,040.89 tons/year, and PM10 is 299.66 tons/year. Meanwhile for the domestic sector, SOx is 0 kg/year, NOx is 14,755.53 kg/year, CO is 4,070.86 kg/year, and PM10 is 190,326 kg/year. Then from the solid waste sector, SOx emissions were 3,653,071.85 g/year, NOx was 21,918,429.85 g/year, CO was 306,858.017.94 g/year, and PM10 was 219,184,298.53 g/year. . The results of the capacity calculation show that the City of Salatiga can still accommodate conventional air emissions for SOx, NOx, CO, and PM10. However, a reduction strategy is still needed to control air pollution. The strategic plan used is an increase in green open space by 20%, the development of an Intelligent Transportation System, emission testing of private vehicles, the substitution of LPG with biogas from organic waste and livestock manure, as well as community development for waste reduction and optimization of waste facilities.

Published: January 2023

Noise may cause serious health problems, including physiological responses, specifically in the cardiovascular system. This study aims to assess occupational noise exposure and analyze the correlation between occupational noise and blood pressure in cabin and station personnel. The participants were 30 cabin personnel (train drivers) and 30 station personnel. The cabin had a Leq of 90.3 dBA while the noise level at Poncol Station was still below the threshold limit value (TLV), i.e., 75.8 dBA. The noise exposure assessment also included noise exposure profiling. The Chi-square test showed that noise influenced systolic and diastolic blood pressure changes. Furthermore, for train drivers, the t-test showed a difference in systolic and diastolic between before and after the activity. As for station personnel, there was a difference in systolic, but contrarily it was not the case in diastolic. According to the noise profile, the train whistle had the most significant noise level at 120 dBA. Moreover, the use of a train whistle regularly may raise the noise level exposure to cabin staff and even station workers. This study contributes to scientific evidence that occupational noise might affect blood pressure

Buildings to achieve sustainable development must meet environmental criteria. This environmentally friendly building design is often referred to as a green building. The Green Building concept aims to reduce the negative impact on the environment from the construction and utilization of buildings. This study will discuss the criteria and requirements that must be met by company buildings to be categorized as Green Buildings according to the Green Building Council Indonesia (GBCI) and obtain a Greenship certificate, as well as any components at the construction and maintenance stage that affect the fulfillment of these requirements. This study uses a quantitative method by the green ship standard version 1.1. The greens criteria assessment in Building A resulted in 51 points. The results of this assessment explain that Building A is included in the silver category. This result explains that 44% of Building A's facilities have met the green building criteria. Upgrading from silver to gold category needs to increase 7 points by adding facilities, standard operating procedures, and policies.

Waste is a very complex and urgent problem to be solved. The problems occur due to the participation of the residents as the leading actor. This study aimed to determine the significance of the influence of gender, age, education, employment status, income, duration of stay, and the level of knowledge on waste generation and management. Respondents to questionnaires and interviews were 37 people whose numbers were determined based on the Slovin equation, while data was analyzed using SPSS Statistics 20 software. A person's educational status significantly positively affects people's habits in reducing waste generation. The following positive significance was income, gender, and length of stay. Age and employment status have a negative correlation, indicating that the older and working, the less waste the society generates. Besides affecting waste generation, it turned out that education also significantly affects waste management. Therefore, education is the main factor considered in waste planning. The results of this study can be used as input for the Indonesian Government in providing information through training and the provision of waste management facilities.

Authors: Rimantho Dino , Putri Gita Azizah
Published: January 2023

Clinical waste is likely to include disease-causing microorganisms, chemical wastes, and other treatments used to treat different conditions, whether solid or liquid. As a result, clinical wastes have a more significant potential for pathogenicity and toxicity than most other types of waste in all of their forms. This study aims to design a strategic decision model for managing medical waste from hospitals. The method used in this research is the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The data was collected using a questionnaire distributed to three people from various fields: hospital waste management experts, academics, and the environmental service. The results show that the preference for the best hospital waste management strategy is SOP improvement with a weight of 0.6576. Furthermore, the alternative of investing in environmentally friendly technology, 3R campaigns, and outreach to employees and visitors received a weight of about 0.4885, 0.2973, and 0.3393, respectively. This study can be a reference for research related to decision-making strategies and the field of hospital waste management.

Environmental performance is significant in today's era. However, the high operational activity of the company has harmed the environment. This study examines the type of industry (TI) and the audit committee (AC) on environmental performance (EP). In addition, this paper uses firm size (FS) as an intervention.  The research uses 198 units of analysis. The results show that the audit committee and firm size affected environmental performance. The type of industry and audit committee affect the firm size. Furthermore, firm size can mediate the relationship of the audit committee to environmental performance. However, the type of industry does not affect environmental performance. Therefore, firm size cannot mediate the relationship between the type of industry and environmental performance. Therefore, the company has to enhance the audit committee's role. Furthermore, the government should enforce regulations related to environmental performance, especially Law No. 32 of 2009 concerning the Protection and Management of the Environment, that all forms of environmental pollution carried out by individuals, corporations or officials can be subject to criminal sanctions. This study has limitations, only focusing on companies listed in the PROPER ranking. Future research could use all companies in many sectors for better interpretation.

In the era of the COVID-19 Pandemic, medical waste is increasing in various hospitals, including UNS Hospital. The variables studied in the hazardous and toxic solid medical waste flow treatment. Primary data was obtained from an analysis of waste amount in 2021 and interviews with incinerator managers. Secondary data in the form of waste types, impacts, and incinerator residue were obtained from the literature study. This research aims to identify solid medical waste management with hazardous and toxic materials compared with Regulation of Environment and Forestry Minister of Republic Indonesia 56/2015. After analysis, it was found that there is dangerous and harmful solid medical waste flow management, distinguished by type. Particular colored medical waste is managed by reducing, sorting, storing, transporting, and destroying. Destruction is conducted with an incinerator. Arah Environmental Indonesia Company operates infectious medical waste. The potential impact of that waste can attack health, damage the environment quality, increase the degradation that has occurred, and pose a threat to microplastic. Completing waste management is done by tightening hospital regulations to produce output according to quality standards, limiting hazardous and toxic waste use, and selecting the waste.
Utilization of conserved genic SSR markers for phylogenetic analysis of Nigerian Ipomoea species

Published: January 2023

Ipomoea, with enormous economic importance, is a large genus with species that are highly evolutionarily diverged. There is dearth of information regarding the phylogenetic relationships of the Nigerian species of the genus Ipomoea. It is therefore imperative to use contemporary taxonomic evidences to understand the diversity of its distribution in a region and provide enhanced delimitation of the taxa. In this study, 6 genic simple sequence repeat (SSR) markers whose cross transferability have been established among the plant species were selected to appraise their level of polymorphism and used to study the phylogenetic relationships among 11 indigenous Nigerian Ipomoea species. The 6 SSR loci showed varying levels of polymorphism among the genotypes of all 11 species assessed and demonstrated 100% polymorphism when examined across the 11 species. A total of 55 alleles were produced. The PIC of the primers ranged between 0.2223 and 0.874 with an average value of 0.71885. Phylogenetic analysis clustered species into 3 major and 6 sub clusters wherein the species were clearly separated. This study has shown the effectiveness of developed genic SSR markers for establishing phylogenetic relationship in Ipomoea species.

Objectives

The congenital embryonic tumor known as sacrococcygeal teratoma (SCT) affects 1 in 35.000–40.000 newborns and is more prevalent in female fetuses and neonates. A total of 25–50% of SCTs are diagnosed by an ultrasound (US) examination during the second trimester of pregnancy. Planning the manner of delivery, determining the risk of negative outcomes, and choosing treatment options depend on the results of antenatal differential diagnosis.

Case presentation

This is a unique case of a 29-year-old second gravida, suspected of having a fetal sacrococcygeal dysplasia differentiable between Type 2 SCT and terminal myelocystocele. An MRI revealed no typical SCT changes, as a matter of course, the diagnosis of myelocystocele could not have been excluded. The results of the genetic examination allowed to exclude the chromosomal pathology. Punctuation of the external component of the formation and a cytological examination were suggested. Nevertheless, the patient and her partner refused further studies and insisted on the termination of pregnancy. Medical abortion was induced and histological findings confirmed fetal morphology to be mature SCT.

Conclusions

Cystic sacrococcygeal teratoma is an unusual malformation of fetal development. In the antenatal period SCT is diagnosed based upon an ultrasound evaluation, an MRI, and a multidisciplinary assessment of clinical experts. Differential diagnosis based upon clinical imaging during the gestational period is elaborate. The final medical diagnosis needs to be verified by a histological evaluation of pathological tissue. An antenatal medical diagnosis of fetal dysplasia is considerable for the further prognosis of fetal and newborn development.
