Authors: Huang Rushi , Chen Shicai , Song Xianmin , Zheng Hongliang
Published: October 2022

Objectives: The aim of this study was to investigate whether the
inhalation of CM-chitosan alleviates tracheal fibrosis in a rabbit.
Methods: We designed a method of cauterizing rabbit tracheal stenosis
with a spherical electrode electrocoagulation. Twenty New Zealand white
rabbits were randomly divided into two groups of ten subjects each: the
experimental group using CM-chitosan and the control group．All the
subjects were successfully established tracheal damage model using
electrocoagulation. On top of this, the experimental group was given
28-days long inhalation of CM-chitosan and the control group was inhaled
saline．The effect of the inhalation of CM-chitosan were measured in
tracheal fibrosis. Results: Laryngoscopy revealed that the tracheal
cross-sectional area of rabbits in the drug group was smaller than that
in the saline group. In the drug group, no abnormality was found in
Heart, liver, spleen, lung and kidney tissues in HE stain and in
non-surgical trachea under scanning electron microscope. Conclusion:
These findings demonstrated that the inhalation of CM-chitosan mitigated
post-traumatic tracheal fibrosis in a rabbit model，which provided a new
way for further treatment study of tracheal stenosis. Key Words:
Tracheal fibrosis, tracheal stenosis, CM-chitosan, inhalation, rabbits.

Published: October 2022

Context and motivation: Design Thinking techniques have been
widely used in the elicitation of software requirements, since such
methods obtain satisfying results when applied to understand the
necessities of both stakeholders and end-users. However, there is a lack
of evidence on their effectiveness when applied to populations
considered vulnerable. Question/problem: What are the
implications of using Design Thinking techniques to elicit requirements
in a community of former inmates - and what would be the benefits of and
challenges in this deployment? Principal ideas/results: In this
paper, we report our experience on using Design Thinking for
Requirements Elicitation of a mobile application, customized for a
vulnerable population: the former inmates of the Brazilian Prison System
and their families. Research approach and methodology: We
utilized the d.school Design Thinking method during our research.
Techniques such as Brainstorming, Stakeholder Mapping, Personas
Creation, Rapid Ethnography, and Interviews were used to obtain relevant
data. Furthermore, during the development process, several prototypes
were created. Contribution: The use of these techniques generated
important contributions for the development of an uncommon application
that aims to help the reintegration process of former inmates into
society. The results obtained validate the initial hypothesis that such
techniques, even when applied to a sensitive context such as this one,
assist in the development of a product that meets the needs of the
end-users by creating a higher quality product. Limitations of
results: The main limitation of the research was the lack of access to
low literacy end-users and/or former inmates without previous experience
using mobile devices.

Published: October 2022

Android occupies a high market share, and its broad functions make
Android security matter. Research reveals that many security issues are
caused by insecure coding practices. As a poor design indicator, code
smell threatens the safety and quality assurance of Android applications
(apps). Although previous works revealed specific problems associated
with code smells, the field still lacks research reflecting Android
features. Moreover, the cost and time limit developers to repairing
numerous smells timely. We conducted a study, including definition,
detection, and impact quantification for Android code smell (DefDIQ):
(1) define 15 novel code smells in Android from a security programming
perspective; meanwhile, we provide suggestions on how to eliminate or
mitigate them; (2) implement DACS to automatically detect the custom
code smells based on ASTs; (3) investigate the correlation between
individual smells with DACS detection results, and select suitable code
smells to construct fault counting models, then quantify their impact on
quality, and thereby generating code smell repair priorities. We
conducted experiments on 4,575 open-source apps, and the findings are:
(i) Lin’s CCC between DACS and manual detection results reaches 0.9994,
verifying the validity; (ii) the fault counting model constructed by
ZINB is superior to NB (AIC = 517.32, BIC = 522.12); some smells do
indicate fault-proneness, and we identify such avoidable poor designs;
(iii) different code smells have different importance and the repair
priorities constructed provide a practical guideline for researchers and
inexperienced developers.

Published: October 2022

The computational Generalized Gradient Approximations (GGA) are applied
on cubic Cesium Lead Bromide (CsPbBr3) with different stress values of
0, 5, 10, and 15 GPa for a supercell with PBE exchange relationship
parameters to study the structural, mechanical, and optoelectronic
characteristics. This study aims to determine how pressure affects
structural and electronic properties, how optical behaviour changes in
reaction to electronic change, and how mechanical properties change as a
result. The structure remains cubic, and there is no phase shift, but a
reduction in the lattice parameters is seen. The reduction in band gap
(1.900 eV) is found from 0-15 GPa and zero at 17 GPa. The partial
densities of states (PDOS) of bulk CsPbBr3, Cs, Pb, and Br are also
calculated. The partial density states PDOS of bulk CsPbBr3 show that in
the valence band range, the sharpest observed peak is for d-states,
while in the conduction region, the sharpest peak is for p-states and
then for s-states. The significant variation in values of absorption,
conductivity (imaginary and real), dielectric function (imaginary and
real), loss function, reflectivity, and refractive index (imaginary and
real) are found by applying stresses of 0, 5, 10, 15 GPa. Using the
energy deformation relationship, the elastic constants are computed.
From these constants, various mechanical characteristics such as the
bulk modulus, shear modulus, Young modulus, and Poisson ratio are
derived and discussed. Additionally, it is a good component in
optoelectronic devices due to its high refractive index, absorption,
reflectivity, and conductivity.
Tri-XGBoost Model: An Interpretable Semi-supervised Approach for Addressing Bankruptcy Prediction
Authors: Smiti Salima , Soui Makram , Ghedira Khaled
Published: October 2022

Bankruptcy prediction is one of the most important research topics in
the area of accounting and finance. The rapid increase of data science,
artificial intelligence, and machine learning has led researchers to
develop an accurate bankruptcy prediction model. Recent studies show
that ensemble methods achieve better performance than traditional
machine learning models for predicting corporate failure, especially
with highly imbalanced datasets. However, the black box property of
these techniques remains difficult to interpret the result and generate
corporate classes without any explanation. To this end, we propose to
build an accurate and interpretable classification model that generates
a set of prediction rules for output. In this paper, a semi-supervised
Tri-eXtreme Gradient Boosting (Tri-XGBoost) is suggested. In the
proposed approach, three different xgboost methods are applied as the
weak classifiers (gbtree xgboost, gblinear xgboost, and dart xgboost)
combined with sampling methods such as Borderline-Smote (BLSmote) and
Random under-sampling (RUS) to balance the distribution of the datasets.
In addition, the xgboost is applied to choose the most important
features which increase the predictive accuracy. Finally, our result is
presented in the form of “IF-THEN” rules to enhance the
comprehensibility of the model by both applicants and experts. Our
proposed model is validated using the Polish bankruptcy imbalanced
datasets. The experimental results confirm the performance of our
proposed method compared to the existing methods with an AUC, G-mean and
F1-score ranging from 91% to 97%.

Published: October 2022

In the recent past, due to the pandemic and humanitarian crisis, the
healthcare system has dived into turmoil, especially regarding core
facilities for women and maternal health. Afghanistan has the highest
maternal mortality rate globally according to the WHO, with a startling
638 deaths per 100,000 live births. In such a decrepit system, regime
changes resulted in major donors withdrawing from the national primary
care service program leading to serious consequences for Afghani women
such as women being compelled to deliver babies at home instead of
hospitals increasing the risk of infections and maternal mortality.
Major challenges faced by the Afghan healthcare system include the
cessation of international funding due to the humanitarian crisis, the
shortage of medicines, and the failure to deliver salaries to healthcare
workers. According to the UNFPA, due to these challenges, more than 90%
of healthcare facilities are at risk of closure, leading to an estimated
4.8 million unattended pregnancies and 51,000 maternal deaths between
2021 and 2025. To ensure such a catastrophe does not arise, the World
Bank, Office for the Coordination of Humanitarian Affairs (OCHA), and
UNFPA in collaboration with governments around the world have pledged
aid, both monetary and in terms of equipment & resources to
Afghanistan. In addition, local Afghan organizations such as the AHDS
and JACK must also be supported to further their work in providing
healthcare services.

Authors: Ashoornezhad Ali , Falaghi Hamid , Hajizadeh Amin , Ramezani Maryam
Published: October 2022

In this paper, the impact of residential photovoltaic (PV) battery
systems in a real test system with the goal of system peak load shaving
is investigated. In order to encourage residential investors, a
Levelized feed-in tariff (LFiT) scheme is introduced. Accordingly, two
proposed cases and relevant suggestions are presented to reach a better
performance. The profitability of the project is apprised via several
economic criteria such as net present value (NPV), payback period years
(PBY), internal rate of return (IRR), benefit to cost ratio (BCR), net
cash flow (NCF), and Levelized cost of energy (LCOE). Moreover,
different levels of peak shaving subject to customers’ participation and
the size of the PV-battery system are also obtained. An actual test
system regarding one-year recorded data is employed to elevate the
precise of results. Furthermore, results are economically compared with
the current situation in the test system to assess the effectiveness of
the suggested system. Obtained results determine the best size of PV and
battery to attain the preferable profitability. Meanwhile, the LFiT with
respect to the economic criteria is specified as well. Finally, a
sensitivity analysis on systems’ parameters is performed to identify the
impact of these parameters on economic indices.
A novel power flow calculation and optimal control method for microgrid based on multivariate stochastic factors fusion - sensitivity
Authors: Shi HongTao , Feng Kun , He Zhuoheng , Chang Jiaming , Chen Tingting , Su Gang
Published: October 2022

The voltage quality of the distribution network may be seriously
impacted by distributed generations (DGs) and load in microgrid. How to
accurately analyze the impact of power flow from microgrid integrated
into the distribution network, to improve the voltage quality of the
distribution network, are needed to be further studied. A novel
microgrid power flow calculation and optimal control method based on
multivariate stochastic factors fusion-sensitivity (MSFF-sensitivity) is
proposed in this paper. The multivariate stochastic factors fusion
(MSFF) function is firstly developed to extract the stochasticity and
correlation of power flow among different stochastic factors in the
microgrid; Further, the fusion-sensitivity (F-sensitivity) for the
stochastic power flow of the microgrid integrated into the distribution
network is created to precisely characterize the influence of various
stochastic factors in the microgrid on the power flow of the
distribution network. Based on this, the power flow of the distribution
network is optimally controlled. Finally, the algorithm verification
shows that, compared with the traditional microgrid power flow analysis
and calculation method, the method proposed in this paper is more
applicable to microgrid. By optimally controlling the power flow of the
microgrid， the voltage quality of the distribution network can be
improved.

Malignant melanoma poses a clinical diagnostic problem, since a large number of benign lesions are excised to find a single melanoma. This study assessed the accuracy of a novel non-invasive diagnostic technology, hyperspectral imaging, for melanoma detection. Lesions were imaged prior to excision and histopathological analysis. A deep neural network algorithm was trained twice to distinguish between histopathologically verified malignant and benign melanocytic lesions and to classify the separate subgroups. Furthermore, 2 different approaches were used: a majority vote classification and a pixel-wise classification. The study included 325 lesions from 285 patients. Of these, 74 were invasive melanoma, 88 melanoma in situ, 115 dysplastic naevi, and 48 non-dysplastic naevi. The study included a training set of 358,800 pixels and a validation set of 7,313 pixels, which was then tested with a training set of 24,375 pixels. The majority vote classification achieved high overall sensitivity of 95% and a specificity of 92% (95% confidence interval (95% CI) 0.024–0.029) in differentiating malignant from benign lesions. In the pixel-wise classification, the overall sensitivity and specificity were both 82% (95% CI 0.005–0.005). When divided into 4 subgroups, the diagnostic accuracy was lower. Hyperspectral imaging provides high sensitivity and specificity in distinguishing between naevi and melanoma. This novel method still needs further validation.

A NONLINEAR PROBLEM IN THE INFORMATION CHANNEL WITH A POISSON COMPONENT
Authors: VODOVOZOV ALEXANDR M.
Published: October 2022

The article considers the process of data transmission over an information channel with frequency modulation, in which the carrier signal is a pulse stream with a Poisson distribution of events. The information parameter of such a signal is the instantaneous flux density. In practice, in the existing typical signal processing structure, the instantaneous density estimate is replaced by the flux intensity estimate, which results in an error from the statistical smoothing of nonlinearity in the process of signal conversion on the receiving side to conflicting requirements for the choice of system parameters during its optimization. The situation is analyzed in dynamic modes, when the signals transmitted over such a stochastic channel change in time and the information flow becomes non-stationary. The data processing operation is considered due to the non-linearity of the channel and the limited sampling period. The paper proposes calculation formulas for the analysis of the methodological error caused by the statistical smoothing of the channel nonlinearity. The free-distribution Scilab software package was used to verify and confirm the results of theoretical studies

The purpose of the study is to justify the use of an applied digital platform in the examination of elements of hazardous industrial facilities (HIF) at a metallurgical enterprise. The introduction of an applied digital platform corresponds to the priority areas of scientific and technological development in the Russian Federation: “Transition to advanced digital, intelligent production technologies, robotic systems, new materials and design methods, development of systems for processing large amounts of data, machine learning and artificial intelligence” and increasing competitiveness expertise of hazardous industrial facilities. In the course of the study, the structure of the applied digital platform (ADP) has been developed, which takes into account obtaining information about the state of the HIF elements, using unmanned aerial vehicles that move along a model trajectory and applying a set of algorithms for the implementation of software modules. Software modules perform the functions of analyzing the current state of HIF elements, studying the dynamics of destruction and building a digital shadow of HIF elements. The studies have been carried out since 09.01.2021 to the present at PJSC “Magnitogorsk Iron & Steel Works”. In the course of the study, the structure of the ADP, a set of software modules for assessing the state and dynamics related to the quality of hazardous industrial facilities using an applied digital platform, algorithms for analyzing the current and future state of the quality of hazardous industrial facilities were developed; 10 modules were implemented at three technological levels. When using the digital shadow of the hazardous facility, it is possible to characterize a hazardous industrial facility only in the conditions of obtaining information on its state, thus a promising direction of further research is the development of a digital twin of the facility. The synthesis of digital twins will allow accumulating retrospective information on the change in the state of HIF.

Authors: SINITSYN NIKOLAY N. , ZAPATRINA NATALIA V. , DONTSOVA JULIA V.
Published: October 2022

Dry granulation plants of blast furnace slag allow obtaining granulated slag and use heat of liquid slag. When introducing dry granulation of slag, emissions of harmful sulfur compounds into the atmosphere are excluded. When designing the granulation chamber, it is necessary to evaluate the main size of the chamber - its diameter to avoid slag sticking to the walls of the chamber. The slag droplets must solidify before colliding with the wall. In this work, the authors developed a mathematical model for the movement of a single droplet of molten blast furnace slag during dry granulation, which allows controlling the cooling process of a single droplet of molten blast furnace slag in the granulation chamber.

Concepção de ser humano na Clínica Ampliada
Authors: Roehe Marcelo V. , Prazeres Daniele Rosa dos
Published: October 2022

A Clínica Ampliada é uma das diretrizes que a Política Nacional de Humanização propõe, a fim de qualificar o modo de se fazer saúde pública. Está fundamentada em ideias que remetem à revisão do entendimento tradicional da saúde, o qual privilegia doença, sintoma e cura, objetivismo positivista e intervenção prioritariamente orgânica. Como alternativa, a Clínica Ampliada propõe a valorização do humano em seu contexto e em sua história de vida. O artigo desenvolve o pensamento de que a essa ampliação da clínica subjaz uma concepção de ser humano, uma vez que a caracterização de qualquer fenômeno humano implica um entendimento a respeito de como é o humano. Argumenta-se que a concepção analítico-existencial de ser humano, elaborada pelo filósofo Martin Heidegger, é compatível com a visão de ser humano implícita na abordagem da Clínica Ampliada à saúde, uma vez que também amplia a visão tradicional de ser humano, ao descrevê-lo como ser-no-mundo.

Published: October 2022

This study evaluated technical efficiency of cowpea production in Nasarawa State, Nigeria. The specific objectives were to determine socio-economic characteristics of the cowpea farmers, estimate costs and returns of cowpea production, evaluate the technical efficiency of cowpea production, evaluate the determinants of technical efficiency of cowpea production, and identify the constraints militating against cowpea production in the study area. Multi-stage sampling technique was adopted and employed. Data for this study was collected from the primary sources through well-structured questionnaires. The results of the analysis show that majority (79%) of the sampled cowpea farmers were male, the average age of the sampled farmers was 45 years indicating that they are still active and agile operating at a small scale level of 2.14 ha farm size. The study further shows that cowpea production is a profitable agribusiness with 2.8% return on investment. Factors that are statistically significant influencing the total output of cowpea production by the famers in the study area were seed (P<0.05), organic manure (P<0.01), chemical fertilizer (P<0.01) and agrochemical (P<0.05) while the factors influencing inefficiency of cowpea production were sex (P<0.01) marital status (P<0.01), education level of farmers (P<0.01), occupation (P<0.01) and household size (0.01). The farmers were able to attain 78% level of technical efficiency with inefficiency gap of 22% of inefficiency that needs to be filled. The cowpea farmers were faced with following constraints: pest and insect problem, poor storage facilities, poor marketing, access to credit facilities and poor infrastructure. Therefore, the study recommends that farmers should be encouraged to participate more in cowpea production since its production is profitable in the study area, farmers should also be provided with subsidized production inputs by government or non-governmental organizations like insecticides, herbicides, and credit facilities to increase their level of production capacity that will lead to increase in total output, income as well as improved welfare that will liberate them from poverty and make them food secured in the study area.

Modeling functional control unit by matrix indicator on basis of programmable logic integrated circuit
Authors: Shurshev Timofei Valerievich , Karlina Elena Prokofievna
Published: October 2022

The article presents the process of simulation of the functional control unit of a matrix indicator on the basis of a programmable logic integrated circuit in the Xilinx Vivado Design Suite tool programming environment. Analysis and synthesis of the hardware language constructs, as well as developing RTL models were carried out using the Xilinx ISE software. There have been defined the functional modules common to the matrix indicator control unit:

a finite state machine that generates a sequence of characters; a matrix indicator control unit that outputs a sequence

of characters to a matrix indicator generating a finite automaton; a button bounce filter; frequency divider. A logic unit model combining functional nodes has been realized. Xilinx ISE CAD produced an RTL model that shows interaction of the nodes and the appearance of the top level. The matrix indicator control unit is presented as four interrelated devices: a column counter that enumerates the columns; a column decoder that takes input values and produces the value "1" only to one of the outputs, the number of which is equal to the number of the column whose value is put to the input; a character code register which receives, stores and transmits character codes; read-only memory which stores encodings of lines for sending an information signal in case of arrival of a particular word or a column. The specific features of implementing the modules on programmable logic are considered. A test module developed in the Verilog language was designed for verification, which is a step-by-step input of values and delays between input. Testing the modules that make up the matrix indicator control unit was carried out.
Probabilistic duopoly model
Authors: Mikheev Andrej Vyacheslavovich
Published: October 2022

A probabilistic model of the duopoly market is constructed. The model is based on the assumption of the random nature of economic variables that determine the market behavior of consumers and competing firms: purchasing power; total costs associated with the production and sale of a unit of goods; commodity prices set by firms. Within the framework of the constructed model, expected values of the profit received and the amount of goods sold were found in the form of functionals of the probability density functions of purchasing power, costs, and prices for goods. Several special cases are considered when the laws of distribution of purchasing power, costs and prices are either exponential or degenerate. In each case numerical modeling was carried out, types of duopolistic relationships between the firms leading to Cournot and Bertrand market equilibria were determined, and economic criteria for the stability

of these duopoly market equilibria were established. It is shown that if all random variables included in the probabilistic model have exponential distribution laws, then in the duopoly market may arise an equilibrium state that is different from the Cournot equilibrium and the Bertrand equilibrium.

Evolución de la actividad agropecuaria en el siglo XXI de acuerdo con los datos del censo agrario
Authors: Gamazo Chillón Juan Carlos
Published: October 2022

En este estudio analizamos los datos aportados en los censos agrarios elaborados por el INE en 1999, 2009 y 2020, y publicados en 2002, 2011 y 2022, respectivamente. El objetivo es mostrar, no solo la situación actual del sector agropecuario español, sino reflexionar sobre la evolución de este sector a lo largo del siglo XXI. Estos censos en concreto proporcionan información de la estructura de las explotaciones agrarias: número, tamaño, tipo de producción, régimen de gestión, etc. Ello nos permite caracterizar al sector agrario español: cuantificando y valorando la magnitud de las principales variables agrarias y ganaderas, y estudiando su evolución a lo largo del presente siglo. La razón última de esta investigación es la búsqueda de un diagnóstico acertado de este sector productivo, una radiografía lo más fidedigna posible, como requisito previo para el diseño e implementación de políticas públicas adecuadas al campo español y para una aproximación propicia al estudio de los problemas y fenómenos agrarios por parte de otras ramas científicas.
Agricultura Urbana, un camino para enfrentar nuevos retos: Estudio de caso de la ciudad de Palencia
Authors: Bartolomé Sualdea Ana María , Urbano López de Meneses Beatriz
Published: October 2022

La presente investigación tiene por objeto analizar el potencial de la agricultura urbana para afrontar los nuevos problemas y retos que se plantean las ciudades, en un estudio de caso de la ciudad de Palencia en Castilla y León. Para ello, se han analizado los retos establecidos en la Estrategia de Desarrollo Urbano Sostenible e Integral (EDUSI) de la ciudad y la posible contribución de la agricultura urbana a los mismos. Se ha calculado, con los datos del sistema de información geográfica agrarios, el potencial de agricultura urbana procedente de la recuperación de terrenos hortícolas abandonados. Mediante encuestas semiestructuradas y visitas a los gestores de las iniciativas de agricultura urbana se ha analizado la posible contribución de la agricultura urbana a los nuevos retos a los que se enfrenta la ciudad.  Los resultados muestran una drástica disminución del terreno hortícola en la ciudad de Palencia, ofreciendo un potencial de recuperación con grandes oportunidades multifuncionales. Sin embargo, las experiencias de agricultura urbana muestran que se necesitan gestores a cargo, así como un análisis pormenorizado del posible suelo agrario utilizable, y resolver la concesión de dicho suelo agrario, junto con un mayor apoyo y regulación de la actividad que permita desarrollar modelos urbanos de agricultura con  su multitud de funciones: social, ocupacional, de ocio, participativa,  productiva, proporcionar espacios seguros al aire libre y cumplir una función de autorregulación natural de los ecosistemas.
Variable Schwa Deletion in French of Orléans: The Role of Age as a Sociolinguistic Factor: A CORPUS STUDY
Authors: Belhoum Sonia , Abdelkader Lotfi Benhattab
Published: October 2022

The present paper is a micro diachronic and a socio-comparative study which examines the behaviour of a well-known pronunciation variant in French, the so-called schwa. The aim of it is to understand the nature of this variation (elision and maintenance) in monosyllabic words; clitics (#c(ə)#c) in French of Orléans, considering age as a sociolinguistic factor leading to this simplification process. Also, the evolution of the variational behaviour of this vowel in the same context across a diachronic interval of forty years (from 1968 till 2014) will be studied. 
To achieve the research objectives, a corpus-based research procedure was implemented, using ESLO Corpus “Enquête Sociolinguistique à Orléans”. It is divided into two sub-corpora ESLO 1 (collected between 1969 and 1974) and ESLO 2 (collected starting from 2014). Based on the findings, it comes clear that the young generation drops more frequently schwa in their spontaneous speech. Their rate of elision was higher in both corpora compared to the one of the old speakers (34,6%, for the old generation compared to 41,7% for the young one). Yet, it is found that the increase of schwa deletion through the diachronic period of forty years is not highly significant. However, it was found that schwa deletion is conditioned by other linguistic and sociolinguistic variables which have not been addressed in this research paper. Consequently, the discussion is left for future research.
How can we strengthen the integration of findings in communication sciences?
Authors: Potthoff Matthias
Published: October 2022

Individual studies in the empirical social sciences have limited explanatory power, as they focus on particular aspects of the overarching objects of research. To explain complex communicative phenomena or describe multistep processes, individual findings need to be combined. Often, however, such an integration does not occur, and opportunities to expand the explanatory power of existing results beyond their immediate scope remain unexploited. Drawing from examples in practical research, this paper describes six metatheoretical, methodological, and context factors that explain why a higher degree of co-creation and integration remains unrealized. A good understanding of these factors can easily be translated into measures that can achieve more integration and make our results more impactful. Furthermore, the illustration of the six factors indicates where integrable findings can be found in this fragmented research landscape. The resulting recommendations are made in the hope that integrative work will be upgraded and further established as a methodological niche in the generation of insights.
7. Ad-hoc-Stellungnahme zur Pandemie durch SARS-CoV-2/Covid-19
Authors: Knipp-Selke et al.
Published: October 2022

The 7th ad hoc statement by the group of authors of theses papers deals with the subject of the changed STIKO recommendation of May 25 on vaccination in children. Surprisingly, on May 24, the Standing Committee on Vaccination (STIKO) came out in favor of the (single) vaccination of healthy children aged 5 to 11 with an mRNA vaccine, preferably with Comirnaty. However, the studies on which the amended recommendation is based relate exclusively to adults; the scientific justification does not provide any evidence for this age group. Consequently, the STIKO also says that the recommendation is being made as a precautionary measure because a renewed increase in SARS-CoV-2 infections is to be expected in the coming autumn. It is unclear whether a new variant will come at all (probably) and whether the vaccine based on the wild type will help against it (questionable). Status: June 23, 2022, 6:00 p.m

PT. Perkebunan Nusantara XII Kebun silosanen is one of the state-owned companies in Jember Regency which is engaged in the processing of robusta coffee (green bean). The problem is the mismatch between the company's plan and the seasonally variable market demand, which affects the inventory that must be held, which results in situations like stockouts and overstocks and drives up storage costs. The purpose of this study is to evaluate using two methods, namely fuzzy Tsukamoto and Mamdani. Then determine the best method using mape values and make a company production plan using 3 input variables, namely the amount of demand, inventory and quality realization. The results showed that Tsukamoto's fuzzy method was chosen as an alternative method to be used in the production plan for the next period. The MAPE value obtained is "good" because it is between 10-20%, which is 11.9%. The simulation results of Tsukamoto's fuzzy model for the production plan were carried out using the DES Brown forecasting method (supply, demand) and the SES method (quality realization). The data from the production plan using Tsukamoto fuzzy for July 2021 – December 2021 are 55,945 kg, 35,614 kg, 52,501 kg, 57,097 kg, 60,477 kg, and 61,545 kg, respectively

Authors: Trujillo Vallejo Diana Marcela , Arango Giraldo Ana Isabel
Published: October 2022

La Corte Constitucional por medio de la sentencia objeto de análisis T- 043 de 2020 confirmó su postura jurisprudencial frente al alcance que tiene la estabilidad laboral reforzada frente a las mujeres embarazadas, en cumplimiento de las diferentes políticas públicas y medidas legales que desarrollan la obligación de garantizar el mínimo vital de las mujeres gestantes y lactantes; así como la  procedencia de la acción de tutela en dicha materia para evitar un perjuicio irremediable cuando las razones para no continuar con la relación laboral, no obedecen a causas objetivas legales según la legislación interna. En este sentido, este análisis pretende abordar los alcances de la sentencia de la Corte respecto de su objeto de desarrollo, y, evidenciar la importancia de este articulo como reseña jurisprudencial en el marco investigativo de corrección constitucional sobre la protección reforzada que deben tener las mujeres gestantes en Colombia de todo acto discriminatorio que obedezca precisamente a su estado gravidez, como argumento ilegitimo e ilegal para finalizar o no renovar un  contrato laboral; cuando no se configuren las causales objetivas para la terminación del mismo según lo dispone el Código Sustantivo del Trabajo.
