Urtica dioica is the flowering herbaceous perennial plant of family Urticaceae distributed globally but commonly considered as a weed in agricultural production. Stinging nettle is one of the emerging plant which has number of medicinal, curative value along with serving as the food and nutritional value in the house of people living below the poverty line. Despite of its million benefit it does not gain much popularity as it deserve. In agricultural production it is considered as weed so removed from the main field. However if the plant is planted in collaboration with other plants it fulfill both nutritive value and serve the main plant with low infestation of disease as pest as stinging nettle avoid the closeness of insect pest as it consist of thorn and also possess host plant resistance characteristics. The plant is only famous in the local rural level and still number of research is to be carried out to transform the globally distributed weed to marketable plant so as to finalize its medicinal value.

Authors: Vista S.P. , Timilsina S.
Published: January 2023

In Nepal, rice is the major staple food crop and is ranked first as a cultivated crop. Nitrogen is one of the most important factors limiting its yield. There has been an overuse of nitrogen fertilizer in rice fields resulting in low N use efficiency and high loss of nitrogen. A field experiment was carried out on acidic sandy loam soil of the Directorate of Agricultural Research, Gandaki, Lumle, from June to November 2016 and 2017 to evaluate the performance of cold-tolerant rice (Lumle-2) and nutrient use efficiency as affected by various levels of nitrogen application. The experiment was laid out in a randomized complete block design with five different level of nitrogen as treatments (0, 50, 100, 130, 150 Kg N ha-1) and replicated four times. Phosphorus, potassium and FYM were applied at the recommended dose. A significantly marked increment in grain yield was noticed in both years as the nitrogen level increases up to 130 Kg N ha-1. However, when the nitrogen dose exceeded 130 Kg N ha-1 have decreasing effect in grain yield, straw yield and NUE. The productivity (4.35 t ha-1) and NUE of cold tolerant rice (Lumle-2) can be improved significantly by applying an optimum level of N fertilizer up to 130 Kg N ha-1.

El Semillero Interdisciplinario de Ingeniería de la Facultad de Ingeniería de la Universidad de Antioquia es una actividad de orientación profesional, para estudiantes de últimos años de bachillerato, que busca desarrollar el interés por la ingeniería, educar sobre los impactos de la ingeniería en la sociedad, así como promover los programas ofrecidos en la Facultad. Para el Semillero se ha desarrollado un aula virtual, con contenidos y actividades para ser revisados y realizados por los participantes de manera autónoma. Se propone un proyecto para ser trabajado durante las 9 semanas de duración del Semillero, en el cual los participantes tienen un acercamiento a las etapas del proceso de diseño de ingeniería, para que propongan una solución factible a una problemática, requiriendo la participación de diferentes ramas de la ingeniería, es decir, interdisciplinariedad. Durante los años 2020 y 2021 se abrieron 4 cohortes, en las cuales participaron y completaron las actividades propuestas 202 estudiantes, principalmente de instituciones educativas de Antioquia, así como de algunas otras regiones del país. Este trabajo presenta la valoración del impacto que ha tenido el Semillero en cuanto a la percepción de los participantes por la ingeniería y el trabajo de los ingenieros, así como las dificultades para la realización de las actividades y del proyecto propuestos. En términos generales se obtuvo que, tras realizar el Semillero, los participantes identifican como habilidades de los ingenieros la creatividad, la solución de problemas y el liderazgo. Sin embargo, no hay claridad sobre la relevancia de las habilidades para el trabajo en equipo y la interdisciplinariedad. En cuanto a la percepción de la ingeniería como profesión, se identifica como beneficiosa para la sociedad, que implica, principalmente, responsabilidades intelectuales e interesantes, que requieren múltiples conocimientos para desarrollar productos tecnológicos. No demuestran claridad en cuanto a que la ingeniería puede ser una opción profesional para cualquier persona, ni los prospectos económicos de la profesión; tampoco con respecto a la formación matemática que implica. La incompatibilidad horaria, los compromisos escolares y limitaciones tecnológicas son las mayores dificultades para que los participantes desarrollen satisfactoriamente las actividades y el proyecto del Semillero. El Semillero Interdisciplinario de Ingeniería posibilita a los participantes adquirir un entendimiento general de la ingeniería y su impacto en el medio y la sociedad. Así mismo, se promueve el interés y aprecio por la ingeniería y el quehacer del ingeniero.
Los Sistemas de Información Georreferenciada como herramienta para la reflexión del contexto territorial en estudiantes de Ingeniería que hacen práctica social
Authors: Oviedo Torres Blanca , Contreras Borja Cristian Camilo
Published: January 2023

Los estudiantes de Ingeniería que hacen proyectos sociales, en contextos comunitarios, requieren información precisa y estructurada para la correcta ejecución de los proyectos, los cuales deben contar con la visión y aporte de organizaciones base, fundaciones o comunidades no organizadas. Por lo general, las organizaciones base y las fundaciones tienen su información disponible y adecuadamente presentada mientras que la comunidad no organizada no suele tener documentado su territorio junto a sus procesos comunes. La información geográfica es uno de los elementos principales de descripción del territorio que una comunidad habita. Se encuentra que las fuentes oficiales suelen estar rezagadas ante las realidades y dinámicas de las personas y de los barrios, al igual que la publicada por reconocidas plataformas virtuales. Una de las razones de que esto ocurra es la marginalidad en la que se encuentran algunos sectores de la ciudad que impiden la rápida actualización de la información oficial, otra es el esfuerzo y costo que se requiere para mantener con datos recientes las bases cartográficas públicas. Es por ello, que el Programa Social PROSOFI ha venido construyendo mapas con información georreferenciada del territorio de trabajo ubicado en la Unidad de Planeación Zonal La Flora de la localidad de Usme. Estudiantes de Ingeniería de Sistemas, por dos años, han generado una base cartográfica que ha servido de reconocimiento del territorio y facilitado el análisis del contexto a otros estudiantes de Ingeniería y de otras disciplinas quienes se unen en torno a proyectos desarrollados con los habitantes del territorio. De manera especial, los mapas le han servido a la misma comunidad para que se reconozcan de mejor manera y utilicen la información compartida en diversas actividades y procesos territoriales. El uso de las tecnologías de información basadas en datos geolocalizados ha permitido proporcionar un sentido más profundo a los elementos recolectados combinando la exactitud de los Sistemas de Información Geográfica con lo volátil que puede ser la información social de una comunidad. Así mismo, ha logrado facilitar los diálogos interdisciplinares y comunitarios, organizar la información existente, y tener una referencia a manera de línea base para un posterior análisis multitemporal de los cambios del territorio, mediante la unión de diferentes plataformas que incluyen la toma de puntos en tiempo real, visualización y consulta de datos de manera gráfica y escalabilidad de los mapas. El paso a seguir es georreferenciar el trabajo realizado con las personas a las que se llega con los distintos proyectos y acciones, con el propósito de tener claridades acerca del impacto de la Universidad debido su trabajo de extensión con las prácticas sociales de Ingeniería.

¿Son las pruebas Saber Pro un indicador de calidad para la evaluación curricular de los programas de ingeniería del país?
Authors: Agudelo Flórez Sergio , Salazar Jiménez Augusto Enrique , Gil Mesa Claudia Pilar
Published: January 2023

Actualmente la normatividad nacional e internacional en procesos de acreditación requieren de estrategias que permitan evidenciar los avances en los indicadores de calidad que cada Institución de Educación Superior IES del país se ha formulado. Las pruebas SABER PRO están siendo usadas por algunas de ellas para mostrar el grado de aprehensión de las competencias por parte de los estudiantes fruto de sus planes de formación y el desarrollo de sus microcurrículos. Se muestra a partir de un análisis exploratorio inicial de los diferentes resultados en cada una de las competencias genéricas que forman parte de la prueba SABER PRO entre los años 2016 y 2020 teniendo en cuenta variables sociales, geográficas y de modalidad de enseñanza, que el uso de estos resultados para poder evidenciar los aportes en los indicadores de calidad deben ser analizados mucho más en detalle y no solo como un ranking entre los mejores puntajes globales obtenidos por cada una de las IES.

Published: January 2023

For the past decade, the prevalence and mortality of methamphetamine (METH) use have doubled, suggesting that METH use could be the next substance use crisis worldwide. Ingested METH is transformed into other products in the liver, a major metabolic organ. Studies have revealed that METH causes deleterious inflammatory response, oxidative stress, and extensive DNA damage. These pathological damages are driving factors of hepatocellular carcinoma (HCC). Nonetheless, the potential role of METH in HCC and the underlying mechanisms remain unknown. Herein, we found a higher HCC incidence in METH abusers. METH promoted cellular proliferation, migration, and invasion in two human-derived HCC cells. Consistently, METH uptake promoted HCC progression in a xenograft mouse model. Mechanistically, METH exposure induced ROS production, which activated the Ras/MEK/ERK signaling pathway. Clearance of ROS by NAC suppressed METH-induced activation of Ras/ERK1/2 pathways, leading to arrest of HCC xenograft formation in nude mice. To the best of our knowledge, this is the first study to substantiate that METH promotes HCC progression and inhibition of ROS may reverse this process.

Published: January 2023

Social-emotional learning (SEL) is an essential part of students’ learning journey. Teachers’ perceptions of SEL have been associated with teaching outcomes and the effectiveness of its implementation in classrooms. In Ontario, SEL is a mandated component of some curricular areas. It is important to consider teachers’ perceptions and experiences regarding SEL because a teacher who is confident in implementing SEL strategies may contribute to positive social, emotional, and academic outcomes for their students. This study explored teachers' perceptions and experiences regarding SEL before and during the COVID-19 pandemic. Three elementary teachers in Ontario implementing SEL practices took part in a semi-structured interview that followed a modified version of Seidman’s (2019) three-interview protocol, and was informed by the CASEL (2021b) framework. Research findings reveal for the first time in the literature elementary teachers’ perceptions and experiences on SEL during the COVID-19 pandemic in Ontario. The benefits and barriers of teaching SEL competencies to students were discussed, as were the SEL strategies implemented by the teachers and professional development received on it. Implications for practice were also described.

En Ecuador se han realizado varias actividades en pro de desarrollar al gobierno electrónico y mediante este intermedio acercar el Estado al ciudadano, con el objeto de hacerlo más transparente, eficiente, eficaz, el gobierno electrónico no solo se entiende por dotar de equipos de cómputo a los funcionarios o tener red de internet inalámbrica (“wifi”) en las instituciones públicas, o que las instituciones públicas tengan páginas informativas en el internet o las denominadas páginas web; gobierno electrónico implica direccionamiento de la política pública debiendo generarse un conjunto amplio de normativas, con lineamientos específicos, que procuren no caer en antinomias (contradicción entre dos leyes), es decir que el contenido de la normativa debe ser acorde a lo que el pueblo quiere o necesita. La metodología utilizada para el presente trabajo de investigación se enmarca en una revisión bibliográfica de tipo documental, ya que nos vamos a ocupar de temas planteados a nivel teórico como es los medios tecnológicos registrales como herramienta de servicio y no como obstáculo al usuario. La técnica para la recolección de datos está constituida por materiales electrónicos, estos últimos como Google Académico, PubMed, Science direct, entre otros, apoyándose para ello en el uso de descriptores en ciencias de la salud o terminología MESH. La información aquí obtenida será revisada para su posterior análisis. La implementación del gobierno electrónico trae consigo muchos beneficios tanto para el Estado, Cantones y Municipios como para los usuarios, porque fundamentalmente reducen costos para ambos, hay una desconcentración de usuarios a manera presencial en las oficinas de recaudación o tramites, permite la solicitud de tramites a usuarios en cualquier parte donde este se encuentre, reducción del uso del papel e impresión en las oficinas municipales, rapidez en la emisión de los tramites en línea, capacidad de mayor recaudación tanto tributarias como de otros servicios. Sin embargo, para que ambos actores obtengan dichos beneficios las plataformas tecnológicas disponibles para los procesos registrales de los usuarios deben estar en óptimas condiciones y con las menores trabas posibles, para lograr un registro exitoso y que ese nuevo contribuyente aporte para la gestión pública local, estatal y nacional.

Authors: Muñoz Cabas Diego , Cando Caluña Wilson , Cando Herrera Fresia , Cando Herrera Joyce
Published: January 2023

Resumen: La Malaria es una enfermedad mortal producida por el parasito del género Plasmodium la misma que es transmitida por la picadura del insecto hembra Anopheles siendo el vector principal con cinco cepas registradas, con 250 millones de muertes en el mundo según la literatura, pero en Ecuador las especies más comunes son por Plasmodium Vivax y Plasmodium Falciparum. La información se obtuvo por medio de una revisión bibliográfica, aquellas disponibles desde el sitio del Ministerio de Salud Pública. Se recuperaron artículos de revistas a nivel nacional e internacional de base de datos, como SciELO, P. vivax information hub, demás archivos digitales del MSP y otras revistas de acceso abierto Casos registrados por la Malaria de P. Vivax desde el año 2018 a 2022. Dentro de los resultados obtenidos en la investigación se observó que del total de casos por malaria por Plasmodium vivax en los años 2018 al 2022 presentó un aumento progresivo con predominancia en el año 2021, en cambio del total de casos por malaria de Plasmodium Falciparum presentaron un aumento de durante el año 2019 y luego una tendencia decreciente, por ultimo evidenciamos los casos por malaria complicada de Plasmodium Falciparum siendo los cuales son pocos casos en comparación con las otras dos clasificaciones encontrando que en el 2021 hubo el aumento; con esto podemos concluir que el descenso de número de casos de malaria en Ecuador, refleja que el actuar del MSP y sus políticas de prevención y manejo de la enfermedad fueron efectivas.

Published: January 2023

En general, las vasculitis de vaso pequeño, cuando comprometen el riñón, provocan una glomerulonefritis, con un fenotipo histológico más proliferativo en aquellas vasculitis por complejos inmunes, y un carácter más necrotizante cuando son vasculitis asociadas a ANCA. Las vasculitis renales asociadas a ANCA corresponden al mayor porcentaje de las vasculitis observables en la práctica nefrológica. La metodología utilizada para el presente trabajo de investigación, se enmarca dentro de una revisión bibliográfica de tipo documental, ya que nos vamos a ocupar de temas planteados a nivel teórico como es Glomerulonefritis necrotizante. La técnica para la recolección de datos está constituida por materiales electrónicos, estos últimos como Google Académico, PubMed, Science direct, entre otros, apoyándose para ello en el uso de descriptores en ciencias de la salud o terminología MESH. La información aquí obtenida será revisada para su posterior análisis. Esta patología tiene una alta mortalidad de no diagnosticarse ni manejarse de forma rápida, con una esperanza de vida en pacientes sin tratamiento de 5 meses. En pacientes que son tratados adecuadamente existe una sobrevida entre 8 y 9 años en aproximadamente el 80% de los casos, sin embargo, a pesar de la introducción de agentes biológicos e inmunosupresores como tratamiento que han mejorado el pronóstico de la enfermedad, existe una alta probabilidad de daño sistémico con los tratamientos prolongados, más que todo en pacientes con afectación renal en un 40% de los casos con una sobrevida hasta de 10 años. Lo que indica que es una enfermedad severa, crónica, sistémica y con altos porcentajes de recaídas.

Published: January 2023

The article presents results of traits of reproductive ability of Holstein cows of domestic (379 animals) and imported (228 animals) breeding with different genotypes of the leptin gene (LEP) with different milking technologies and housing conditions. Frequency of occurrence of genotypes of LEP gene in imported herd range: CC – 32.5; TC – 49.1 и TT – 18.4 %. In herd of domestic animals frequency of CC, TC and TT genotypes of LEP gene was – 23.5; 54.3 and 22.2 %. In our research it has been shown that animals with the TT genotype of the LEP gene are distinguished by the best traits of live weight at the first fruitful insemination, reproductive capacity coefficient, Dohi index, yield of calves per 100 cows, duration of the calving interval and open days, compared with animals with CC and TC genotypes. Among the cows of domestic breeding, superiority was established for animals with the TC genotype in traits of live weight, service period and Dohi index. For others traits of reproductive ability stand out favorably animals with the CC genotype of the LEP gene. In the context of two farms in the course of the experiment, it is noted that Holstein cows of imported selection with yard housing technology have the best indicators of reproductive qualities, compared with the population of domestic selection of stall barn housing technology. It follows from this that genetic and paratypic factors, along with such herd management principles as milking technology and housing conditions, equally affect the reproductive qualities of Holstein cattle. This research was supported by FASO Russia project number 122011800138-7.

Published: January 2023

Plant protection and the application of mineral fertilizers play an important role in the production of agricultural products. To improve technological processes and develop new models of self-propelled rod sprayers, it is advisable to determine the laws of distribution of their technical parameters. A number of the power distribution of the installed engines of self-propelled rod sprayers has a coefficient of variation of 30.4%, which indicates that the distribution is close to normal. For 95% of the considered models of self-propelled sprayers, the power value of the engines is in the range of 55.1 ... 225.3 kW. It changes approximately 4.1 times, which indicates the presence of many different factors that significantly affect the design features of self-propelled sprayers. In particular, this may be related to consumer requests. Theoretical and empirical laws of a series of mass distribution of self-propelled rod sprayers are presented. The studied indicator has a coefficient of variation equal to 35.1%. With a confidence probability equal to 0.95, it is calculated that the weight of the rod sprayers is 2.69 ... 15.35 tons.

Innovative building materials are considered, allowing the use of new design solutions and the construction of durable structures that meet technical requirements and aesthetic requirements. The main properties, characteristics, objects and methods of application of hydraulic concrete and self-healing concrete are described. Self–healing concrete is a new stage in the development of building materials. The new self-healing concrete differs from classical recipes by adding fungi and bacterial spores to the composition, which can survive in alkaline conditions and give new properties to the building material. From the analysis of literary sources, we came to the conclusion that the long-term operation of various hydraulic structures is affected by water and the environment. All these factors lead to a decrease in the structural strength of hydraulic structures. A new self-healing material is needed in places where the production of minor repairs and regular inspection of the condition of structures is impossible: underground construction; underwater construction; high-rise buildings; bridge-type transport structures. Another advantage of new generation building materials is the possibility of budget savings, since there is no need for constant minor repairs of structures.  The purpose of this work is the research and development of technology for the production of self-healing concrete modified with a micro-biological additive. In accordance with the goal, we analyzed the physical and mechanical properties of concrete and other cement composites, ways to improve them, studied damages and defects that reduce the durability of reinforced concrete structures, the process of structure formation, as well as ways to repair and restore them. Based on the analysis, a technology for creating industrial-scale concrete modified with a microbiological additive and self-healing structures is proposed. This area of research is very promising; the potential profit from the use of such concretes in hydraulic structures is huge.

Published: January 2023

The description of theoretical and experimental studies of ventilation systems of the recuperator type is given in order to modernize the supply and exhaust ventilation system of the laboratory room. The relevance of the study is dictated by the need to resolve the basic technical contradiction between reducing energy consumption and increasing the efficiency of ventilation systems. The recuperator-type ventilation system proposed by the authors has a significantly lower operator complexity factor compared to a common analogue and a higher structural component of engineering reliability. All studies were carried out on the basis of the Institute of Risk Management and Integrated Security of the Orenburg State Agrarian University, and production tests of a prototype fan-recuperator were carried out on the basis of the PnevMax Research and Production Enterprise (Orenburg). The introduction of a new ventilation system for small laboratory premises of agricultural enterprises will ensure the continuity of technological processes in the laboratory space while increasing the efficiency of the use of production resources.
Dangerous products on the contemporary EU market – characteristics of the non-food products
Authors:   The West Pomeranian University of Technology in Szczecin, Faculty of Economics, Hernik Joanna
Published: January 2023

Purpose: For most products, for example, toys, food, cosmetics, there are regulations in European law that define safety requirements. However, each year, several thousand products potentially dangerous for consumers appear on the market. Producers’ organizations, as well as public institutions and consumer organizations are fighting to keep them as few as possible, yet, different market forces play a role here and they are still on the market. Therefore, consumers should be educated and knowledge about such products should be disseminated. Design/methodology/approach: In the research part, the products deemed unsafe in years 2015-2021 were analyzed. Additionally, the 80 latest alerts on dangerous products were also thoroughly analyzed. Data was collected from The European Commission Safety Gate system, The comparative analysis method was used as well as the documentary analysis. Findings: The aim of this article was to identify the main types of risk to consumers, related to the consumption of non-food products. The conducted analysis shows that it is mainly a risk of injury, poisoning, allergic reaction, as well as chocking and suffocation, but the risks vary greatly depending on the product group. It is significant that dangerous products are often intended for children, therefore the conscious attitude of parents is important. Research limitations/implications: It should be taken into account that the situation may change over time, that may be related to new legal norms, to a change in the economic situation on international markets due to new products, to greater awareness of producers, for example. Therefore this type of research should be discussed in a broader context. Practical implications: The analysis shows the need for an alert system against dangerous products. The results indicate that stereotypes about the ‘safe country of origin’ can change; in practice, therefore, consumers need new knowledge about dangerous products which will help them make informed decisions. Up-to-date knowledge is also needed by the sellers – they can make decisions about cooperation with suppliers that will be more favorable to them. Social implications: The awareness of the presence of dangerous products on the market is important for the health of consumers, but it is also important for producers themselves due to the potential damage that can be caused to consumers and the environment. Keywords: conscious consumption, consumer rights, RAPEX, safety of consumption. Category of the paper: Research paper.

Purpose: The purpose of this study is to review the literature on Corporate Social Responsibility (CSR) and Environmental, Social and Governance (ESG) and addresses two research questions: What is the mutual relation between CSR and ESG? and Why CSR and ESG matter to businesses? Design/methodology/approach: The paper applies the method of comprehensive literature review. The analysis of keywords, abstract, and on this basis further deeper analysis of scientific texts allowed to identify the mutual relation between CSR and ESG. Findings: The main conclusion from the conducted analysis is that both concepts - CSR and ESG, apart from being complementary, can be combined not only to improve the strategic management of the organization, but also, in a broader context, to serve the good of both the local community and the whole society. CSR aims to make business responsible, while ESG aims to make it measurable. Research limitations: No empirical study has been conducted to support the findings presented in the study. Originality/value: The paper organizes and systematizes the knowledge on two concepts, i.e., CSR and ESG, which now play an important role in the sustainable management of an organization. Keywords: CSR, ESG, sustainability, reporting of sustainability matters. Category of the paper: literature review.

Purpose: Establishing the way the life history (LH) strategies and gratitude are related to each other. Design/methodology/approach: Life History Theory provides an evolutionary framework for understanding specific developmental paths of species and individuals. There are certain trade- offs during a lifespan of an individual, they must face (for instance, somatic or reproductive effort, quality or quantity of offspring, mating or parenting). Depending on the choices a person makes, they exhibit a slow or a fast life history (LH) strategy. A latent variable underlying a set of solutions (strategy) is called K-Factor and is used to measure individual differences with regard to the pace of one’s LH. People with a slow LH exhibit greater prosociality, tend to form long-term sexual relationships and their sexual maturation is slowed down. On the other hand, gratitude facilitates prosociality and altruism, builds social resources and acts as a moral barometer. In recent years we observe an increasing attention to the issue of gratitude both in academic publications and popular press in various fields including economics, management and organizational sciences. All these disciplines draw from relatively new and contemporarily flourishing field of psychology – positive psychology. We deployed the Gratitude Questionnaire (GQ-6) for the measurement of gratitude and the Mini-K Short Form for the measurement of LH strategies. 197 students took part in the study (138 females, 59 males). Findings: A positive correlation between slow LH strategy and gratitude was found in women. Originality/value: Investigations on the relationship between gratitude and LH strategies show a fragment of the landscape of human personality. Slow LH people seem to be more grateful and thus display more prosocial traits while restraining selfishness which can lead to achieving the delayed social benefits. On the other hand, low-K individuals in organizational context have smaller willingness/ability to reciprocate to their benefactors and to build social bonds. Such individuals presenting exploitative interpersonal style should be detected at the beginning of a selection process by HR specialists. Keywords: life history theory, life history strategies, gratitude, positive psychology, positive psychology interventions in organizations. Category of the paper: research paper.

Published: January 2023

Purpose: The aim of this paper is to present the challenges faced by HR departments in the hybrid work system. In particular new tasks set for HR departments in the conditions of hybrid work organization and competencies necessary for HR professionals to effectively deal with new tasks and challenges caused by the hybrid work settings were analyzed. Design/methodology/approach: A systematic review of world literature was carried out using the following databases: Proquest, EBSCO, Emerald, JSTOR, Science Direct and BAZEKON. The results were supplemented with conclusions from two research conducted by the author on samples of over 100 companies operating in Poland. Findings: A list of tasks anticipated for HR departments as a result of the introduction of a hybrid work system was created. A set of competences necessary for the effective performance of tasks was also proposed. Research limitations/implications: The limitation of research is a very short research time span and large differences in the specificity of companies making it difficult to propose a universal model for each company. Originality/value: The paper presents list of tasks and set of competences necessary in new conditions created by the introduction of hybrid working systems. It can be valuable for researchers and practicians. Keywords: hybrid work, HR department, HR professionals. Category of the paper: research paper.
Lean journey success factors – a case study of lean tools implementation sequence in a manufacturing company

Published: January 2023

Purpose: The study aim is an in-depth investigation of a Lean tools implementation sequence in an organisation as an expression of a Lean journey within that organisation. The success factors of Lean tools implementation and the relationship between them are studied. A model of Lean tools implementation in an organisation is aimed to be developed. Design/methodology/approach: A case study method is employed in this study. It is conducted in a manufacturing company from the fast-moving consumer goods (FMCG) industry. The employed method allows exploitation of a variety of techniques in the investigation process: in-depth interviews, observations, documents and data analysis. The study takes into consideration a systematic literature review and bibliometric network analysis supported by the Vosviewer software tool. Findings: The implementation of Lean Manufacturing approach, along with accompanying tools and methods, is aimed at efficiency and/or quality results of the processes within a company. Selected tools, to be successfully implemented, should support the elimination or reduction of losses related to current process flows. There are many Lean tools available, but most do not fit all organisations and all the kinds of manufacturing processes. Therefore, proper preparation before implementation is an essential issue for any organisation striving for Lean outcomes. The available Lean tools, along with their implementation sequences, are not studied comprehensively in the literature. Originality/value: An organisational-development-driven model of Lean tools implementation is elaborated, based on the literature and empirical investigations. The decision to choose the appropriate Lean tool should be guided by general organisational development. Several factors need to be considered before the implementation process, namely, capabilities, resources, gains and return on expenditure. Top management engagement, appropriate communication and listening to line employees look to be key success factors in Lean tools implementation. Keywords: Lean Manufacturing, Lean tools, Lean implementation. Category of the paper: Research paper, Case study.
