Published: November 2023

In the modern world, English has become widespread only in the “inner circle” countries (Great Britain, Ireland, USA, Canada, Australia and New Zealand) where English is the native language of the population. English is also actively used in outer circle countries. Countries in this circle include India, Nigeria, Bangladesh, Pakistan, Malaysia, Kenya, South Africa, etc. In the “Outer Circle” countries, English is not the native language of a significant part of the population, but it plays an important role in government actions and daily communication. There are also “expanding circle” countries (Russia, China, Japan, Korea, Egypt, Germany, France, etc.) where English is not the native language of the majority of the population and is not used in public administration. In these countries, English is used in some fields of activity such as education, business, science, culture and tourism.

Published: November 2023

Data steganography is widely used in message protection from being read, and mostly used methods based on LSB and LSB2 methods are not enough secure. In this research paper a modified LSB2 method will be introduced. This method will use a complex complicated key to enhance the data protection degree. The key will be used to rearrange the message stream of bits before data hiding and before data extraction. The key will be sensitive to any minor changes giving a corrupted unreadable message when any change was done in the data extraction phase o data steganography phases. It will be shown that the proposed method very efficient comparing with other methods base on LSB or LSB2 methods. The proposed method will add an improvements to the process of steganography by reducing both the hiding and extracting times. It will be shown that the proposed modified LSB2 method will be used to treat any message short or long using any color image, the size of the used covering image will not affect the method efficiency, so we can use bigger covering images to enhance the quality of the stego image by optimizing the value of MSE and PSNR. The proposed method will be implemented and various analysis will be introduced to prove the improvements achieved by the proposed method.

The theory used is Instructional Leadership Theory and the objective was to determine the influence of Principal Leadership on School Goal Framing in Kuresoi Sub-county of Nakuru County, Kenya. A quantitative study approach was employed to gather data through closed-ended questionnaires distributed to 266 participants, consisting of 38 principals, 38 deputy principals, and 190 heads of departments (HODs). The research findings indicate that on an annual basis, principals, deputy principals, and heads of departments engage in collaborative efforts to develop school-wide objectives. The joint effort was consistently undertaken by 42.1% of principals, 36.8% of deputy principals, and 46.3% of heads of departments. Moreover, after examining educational objectives and clarifying faculty duties, it was found that 47.4% of principals and 51.1% of Heads of Departments (HODs) consistently engaged in the procedure. It is worth noting that a significant proportion of deputies, specifically 44.7%, expressed a preference for the “almost usually” category. In contrast, a slightly higher percentage, 47.4%, reported employing needs assessments or other formal procedures to evaluate staff and establish goals. Using student performance data for goal-setting was observed in 36.8% of cases among principals and deputies. Similarly, 38.4% of Heads of Departments (HODs) consistently exploited such data, while 37.9% did so frequently. In summary, the data indicates that most principals (55.3%) and heads of departments (38.4%) frequently formulate explicit and pertinent objectives readily available to educators across different hierarchical levels. The present study addresses a notable void in the current body of literature by providing insights into the unique characteristics of public schools in Kenya and emphasising the crucial significance of principal leadership. The above findings hold significant value for policymakers, educators, and academic institutions, as they can provide guidance and reshape leadership paradigms to promote progress within the education sector.

Published: November 2023

Objective: To identify Helicobacter Pylori (HP) gastritis-associated histopathological changes in Gall Bladder (GB) mucosa in patients undergoing cholecystectomy.
Methodology This prospective comparative cross-sectional study was conducted in the Gastroenterology department of Liaquat National Hospital, Karachi, Pakistan, from December 2021 to December 2022. The study included all patients admitted with a diagnosis of any Gall Bladder pathology and those who were electively scheduled for cholecystectomy. Participants were categorized into two groups based on the presence of HP: group A (HP positive) and group B (HP negative) in gastric mucosa before cholecystectomy. HP detection was performed using various methods, including HP stool antigen (HPSA), Urea breath test (UBT), HP antibodies, and biopsy confirmation through gastroscopy.
Results: The mean age of patients in group A was 42.88 ± 8.28 years, and in group B, it was 43.35 ± 8.74 years (p=0.458). According to the GB histological findings, Chronic cholecystitis with focal Cholesterolosis was significantly more common in group A (75.4%), while Chronic cholecystitis alone was significantly higher in group B (66.2%) (p=0.001). Dysplasia was observed more frequently in group B compared to group A. Erosion was more prevalent in group A, patients than in group B (p=0.001). Although symptom improvement in the HP positive group with persistent symptoms post-eradication was not statistically significant, it did show some improvement (p=0.527).
Conclusion: The histological findings of chronic cholecystitis with focal Cholesterolosis were significantly higher in the HP positive group compared to the HP negative group, while chronic cholecystitis alone was significantly more common in the HP gastritis negative group. Some HP gastritis group patients experienced symptom improvement after HP eradication.
Production of Bacillus subtillis protein mass on the microbial mass of Methylococcus capsulatus
Authors: Sadvakassov Kairat , Islamov Yessenbay
Published: November 2023

The growing demand for food of animal origin has contributed to the annual increase in the agricultural population of productive animals in the world, which in turn has led to a significant shortage of feeds and an increase in their cost. Therefore, the purpose of this research was to explore the qualitative composition of feed products obtained by culturing methanotrophic microorganisms Methylococcus capsulatus with probiotic bacteria Bacillus subtillis. Arbitrage methods for determining the quality of feeds, which are regulated by regulatory documents (ISO), were used in the research. The results of the research demonstrate that the protein product obtained by growing Methylococcus capsulatus culture has a high content of “crude” protein at the level of 60.9%, which corresponds to high-protein feeds of animal origin by its technical characteristics. The addition of probiotic microorganisms Bacillus subtillis to the medium for cultivation significantly improved the qualitative parameters of the synthesised protein by increasing by 1.5% the amount of essential amino acids, increasing by 3.8% fatty acids and increasing the concentration of calcium and phosphorus. The increase in the concentration of lysine, isoleucine, valine and asparagic acid, due to the cocultivation of two microorganisms allowed increasing their nutritional value for cattle since these amino acids are the most demanded in ruminant diets when using corn silage and other plant feeds. The addition of Bacillus subtillis culture allowed reducing the content of “crude” fibre and improving its biological characteristics by changing the microbiological composition of the obtained product. In the future, the biotechnological method of obtaining feed protein for animals will reduce the dependence of animal breeding on the cultivation of fodder crops and weather conditions
Pathological changes in aborted fetuses and placental tissue in cows with neosporosis
Authors: Nyzhnyk Bohdan
Published: November 2023

The failure to obtain offspring due to abortion causes considerable damage to the dairy industry worldwide, costing millions of US dollars. Neospora caninum, a protozoan parasite of the Apicomplexa class, is the causative agent of neosporosis, a disease that leads to abortions or the birth of weak offspring in cows. Therefore, addressing this issue is crucial. The purpose of this study is to describe the pathological changes in aborted fetuses and placental tissue in cows with neosporosis. Macroscopic examination of fetal and placental parts was performed through pathological dissection. The gestation age (days) was determined using the formula: 68 + 2.25×CRL (cm) and/or from historical data. DNA of N. caninum was detected by polymerase chain reaction in all fetuses and/or fetal parts of placentas described in the study. It was found that the majority of abortions occurred at 4-5 months of gestation. External examination revealed isolated instances of skin hyperemia and haemorrhages throughout the body. Some fetuses were mummified. Autolysis of the fetus and placental parts was observed in most cases. Placentitis and oedema of the placental tissue were also noted in some cases. Internal examination of fetuses revealed changes in the brain, skeletal muscles, heart, lungs, liver, spleen, and kidneys, in addition to characteristic autolysis. These changes, including grey foci in the brain with a light grey centre, white foci, and multiple white streaks in skeletal muscles and the tongue, can be attributed to typical pathological changes in aborted fetuses with neosporosis. These changes are rare but can impact the determination of the cause of abortion, narrowing down the factors responsible

Published: November 2023

Demand for chicken meat has been growing in recent years, requiring prominent production levels and efficient feed conversion. The purpose of this study was to determine the productivity, preservation, and slaughter performance of broiler chickens, feed conversion on the background of feeding with additives with chelated forms of trace minerals. Poultry growth intensity was determined according to zootechnical methods, slaughter indicators – according to morphological methods, and statistical analysis of the results was used. By the end of the rearing period, the live weight of broiler chickens in the groups where the dietary supplement with chelated trace minerals (second group) and copper chelate complex (third group) was significantly higher than in the control group – by 6.9% and 13.8%, and the relative increase was 4.5 percentage points and 8.5 percentage points, respectively. The growth rate of broilers in terms of average daily weight gain is higher in these groups by 6.8% and 14.2%, respectively. The safety of poultry in the experimental groups is 4% better than in the control group. The feed conversion of a diet with chelated trace element additives is higher. Feed consumption in the experimental groups was reduced by 2.8% when feeding the selected additive and by 9.7% when feeding the copper chelate complex. The results of balance studies revealed an increase in the digestibility of nutrients in the diet of broiler chickens. Additives with micronutrient chelates are effective in increasing slaughter yield, meatiness of the thighs and shins, and pectoral muscles by 5.3-6.2 percentage points. The broilers of the experimental groups had a higher meatiness of the thighs and shins. The highest growth rate was found in broilers fed a copper chelate complex in their diet. The lower feed conversion in the control group is due to the lower body weight of these chickens. Based on the research data obtained, the possibility of effective introduction of additives with chelated microminerals into the diet of broiler chickens was established, which helped to increase the growth rate and meat yield. The results can be used in farm poultry farms to produce more products and reduce the cost of chicken production
The Role of the Territory in an Educating City: Two Italian Laboratory Examples of Participatory Urban Planning
Authors:   Guglielmo Marconi University, Department of Human Sciences, Rome, Italy, Montebelli Stefania
Published: November 2023

The aim of this article is to stimulate further reflection on the concept of the Educating City by presenting two Italian participatory planning initiatives. The analysis focuses on the benefits of knowledge of the surrounding territory for the development of an informed and engaged citizenry; the key role of the city for education and participatory space in a learning society; and finally, the strategies that have been implemented to educate the community about its territory and encourage active participation in its development. The focus of the reflection is thus the city as an 'open' educational environment, made up of spatial elements that are closely connected through social relations. In this environment, actors influence each other and engage in constructive communication and cooperation to co-create shared living spaces. In this sense, a comprehensive knowledge of the territory can contribute to the development of a cooperative citizenship whose actions influence both the communal living spaces and the social fabric that populates them. Through continuous learning about the territory, the urban community can acquire skills of conscious self-determination and participate effectively in the shaping of urban space. This is a fruitful process that cannot avoid taking into account the 'situated context' and the education that enables the integration needs of the urban community to be incorporated and expressed in the decision-making processes about the future development of its own territory.

Published: November 2023

The ability to understand and master concepts of fractions will provide a solid basis for understanding more complex mathematical concepts which in turn will assist in solving problems involving fractions in everyday life. However, findings of the international assessments Trends in Mathematics and Science Studies (TIMSS) and Program for International Student Assessment (PISA) indicated that the achievement of fractions among pupils in Malaysia is at a poor level, which is below the international average score. In considering the rapid development and advancement of digital games, the purpose of this study is to investigate the effect of DGBL using Minecraft on pupils' achievement in fractions. A quasi-experiment with a pre-test and post-test nonequivalent groups was conducted involving 65 Year Five pupils in two intact classes. Through cluster sampling, one class was selected as the treatment group while the other class was selected as the control group. The treatment group which consists of 31 pupils was exposed to DGBL using Minecraft while the control group which consists of 34 pupils was exposed to conventional methods. Data were analyzed using an independent sample t-test to compare the post-test achievement score mean for fraction between the treatment group and the control group. There was a statistically significant difference in the achievement scores mean between the treatment group (mean=8.80, SD=2.77) and the control group (mean=6.20, SD=2.79). The findings from this study would further encourage the use of digital games, especially Minecraft, in the teaching and learning of fractions so as to increase pupils‟ achievement.

It uses Ralph Tyler’s Basic Principles of Curriculum and Instruction in reviewing SCL teaching and learning assumptions in relation to that of MIB’s national philosophy. In this paper, I present my personal teaching experiences in a private higher education institution in Brunei. Reflexivity is given focus by presenting my experiences as a student in a teacher-centric and learner-centered setting, and from being a teacher in a learner-centered setting in the Philippines and the adjustments I had to make in my first year of teaching in Brunei. I pointed possible issues in the integration of SCL and MIB and its implications to higher education pedagogy. Ultimately, this reflexive account aims to generate discussions about SCL as a paradigm its adaptability in different contexts, and the importance of academic freedom.
Nuevo texto de la Ley General de la Seguridad Social

El Título III regulador de la protección por desempleo, se subdivide en siete Capítulos, de los que los cinco primeros de forma separada, inciden en la regulación, tanto de las normas generales, como del nivel contributivo, nivel asistencial, régimen de las prestaciones y régimen financiero y gestión de estas prestaciones.
Tal vez sea ésta una de las novedades fundamentales de la Ley de 1994: la incorporación en tal texto mediante refundición, de normas de toda la materia que con anterioridad quedaban recogidas a través de normas separadas. Todo ello en función de las previsiones establecidas tanto en la Ley 22/1992, de 30 de julio, sobre fomento del empleo y protección por desempleo como en la Ley 22/1993, de 29 de diciembre, de medidas fiscales, de reforma del régimen jurídico de la función pública y de la protección por desempleo.
La protección por desempleo como tal, podría interpretarse en sentido amplio «como situación temporal de desocupación en que se encuentra una persona, cualquiera que sea la causa que la motive y cualquiera que sea la condición laboral de la persona (asalariada, autónoma), tratándose de una situación equivalente a estar sin empleo, siendo indiferente el origen, la causa, el motivo de la carencia de empleo»; se entiende por desempleo, aquella situación en que se halla quien, siendo habitualmente trabajador por cuenta ajena y encontrándose apto para trabajar, ha de permanecer ocioso y sin prestar sus servicios por causa independiente de su voluntad.

La Sentencia dictada el 17 de octubre de 1994, por la Sala 1.ª del Tribunal Constitucional, deniega el amparo solicitado por el demandante en el recurso interpuesto contra la sentencia de la Audiencia Provincial de Badajoz, que había absuelto a cuatro empleados de una Caja de Ahorros, previamente condenados, en el correspondiente procedimiento abreviado, por un delito de descubrimiento y revelación de secretos.
Contra la sentencia absolutoria de la Audiencia Provincial recurre en amparo el demandante, argumentando que la misma vulnera sus derechos al honor, a la intimidad personal y familiar y a la propia imagen, por cuanto «no sólo no los protege sino que destruye la protección otorgada por el Juez de lo Penal al anular la sentencia dictada por éste».
A) Descripción de los hechos:
En la demanda de interposición del recurso se nos da cuenta:
1. Que el 24 de mayo de 1990, el Director general y otros tres empleados de la Caja de Ahorros de Badajoz procedieron a registrar la mesa de despacho del demandante (Director de la Oficina de Mérida), encontrándose éste ausente.2. Que como resultado del registro efectuado se halló una documentación, de la que era depositario, consistente en un contrato de compraventa concertado entre dos clientes de la Caja y otra persona, y un cheque, en favor de los dos primeros, por un importe de 6.000.000 de pesetas.
Propuestas para una reforma de la protección a la vejez (2.ª parte)

1.er Premio Revista Estudios Financieros 1995.Modalidad: Derecho del Trabajo y Seguridad Social.
En el modelo propuesto de Seguridad Social la pensión de jubilación, junto con la de invalidez, constituiría el núcleo central del nivel profesional obligatorio, encargado de cubrir una función asegurativa que permitiera conservar el poder adquisitivo en la vejez -o el infortunio, para el supuesto de invalidez- y financiado de forma exclusiva a través de las cotizaciones de los trabajadores, siguiendo el principio que subyace al seguro privado, a saber, que es la colectividad de asegurados quien realmente soporta el costo de las prestaciones, con la interposición de la entidad gestora.
Dos cuestiones deben precisarse ya de entrada: de un lado, el concepto riesgo en un seguro social general y la necesidad (o no) de su cobertura con la intervención de una entidad gestora pública, de otro.
La noción de riesgo, ha de aclararse, conviene tan sólo a la ordenación jurídica de la previsión social, no a la construcción jurídica de la Seguridad Social que, en tanto medio o instrumento protector, no puede situarse a la expectativa de que se produzca el hecho, disponiendo los medios para reparar el daño futuro, sino que ha de situarse ex post a la producción de aquél, ordenando los medios destinados a reparar sus efectos una vez acaecido (243).
La cosa juzgada. Alcance y contenido de la cosa juzgada material en los procesos laborales
Authors: Navarro Fajardo Juan José
Published: November 2023

Como afirma Guasp, la cosa juzgada no es sino una consecuencia imprescindible de la idea básica de la institución procesal, efecto necesario del proceso mismo y uno de los dogmas fundamentales del derecho procesal.
Cuando se dice que las sentencias firmes -sobre el fondo- gozan de autoridad de cosa juzgada, se está incluyendo tanto el efecto formal, que se anuda a la firmeza de la sentencia y que provoca la inatacabilidad directa del fallo dentro del mismo proceso, como el efecto de la cosa juzgada que impide la impugnación indirecta del fallo mediante la apertura de un ulterior proceso, en el que se deduzca una pretensión idéntica a la ya resuelta.
Desde luego, este último no es un efecto exclusivo de la cosa juzgada. Antes de la firmeza de la sentencia, la posibilidad de un nuevo proceso puede rechazarse mediante la excepción de litispendencia, precedente temporal, en la mayor parte de los casos, de la excepción de cosa juzgada.
La litispendencia es la excepción producida por la constitución de un proceso anterior en el ulterior en que se haga cuestión del mismo objeto procesal. Examinadas la litispendencia y la cosa juzgada como excepciones procesales, presuponen la existencia de, al menos, dos procesos en los que, dada la identidad de las pretensiones deducidas en los mismos, el segundo se considera superfluo, y, por consiguiente, debe ser excluido.

Los tests psicotécnicos, una herramienta de selección
Authors: Fernández Muñoz Ángel
Published: November 2023

En la entrada al santuario del oráculo de Delfos había una inscripción que decía: «ConÓcete a ti mismo». Eso es, precisamente lo que pretenden los tests, y la ciencia que les sustenta: acceder al conocimiento de uno mismo y de los demás.
La psicometría estudia los principios y los métodos para elaborar medidas psicológicas.
Estas medidas son precisas para realizar con rigor las comprobaciones propias de cualquier ciencia experimental. Todos somos conscientes de la necesidad de la medida en Física, por ejemplo. ¿Ocurre lo mismo en Psicología? ¿Es igualmente necesaria la medida en esta ciencia? ¿Es posible? ¿En qué sentido podemos hablar de «medidas» psicológicas?
La Psicología cuenta con varios métodos distintos. Uno de ellos es el experimental, que exige el uso de la medida.
El objeto de la Psicología es el comportamiento humano, su conducta, sus actos. Ahora bien, la conducta humana presenta aspectos somáticos, se puede observar, someter a experimentación y medir. Con el método experimental, la Psicología trata de descubrir las relaciones entre los aspectos observables de su conducta y su psique. En otros términos: si la Psicología estudia la conducta humana y ésta contiene siempre aspectos externamente observables, es posible utilizar el método experimental. Éste exige la medida. En Psicología la medida se dirige a las estructuras somáticas en que se realiza la conducta. O sea, se verifica sobre la conducta físicamente registrable y observable.
Esta medida es estadística y permite avanzar pronósticos probables acerca de la conducta de grupos y de personas. Con esta finalidad se utilizan en selección de personal.
