In Japan and Germany, the mechanical engineering industry is a significant industrial sector, and the growth of small and medium-sized enterprises (SMEs), which constitute a large proportion of the number of firms and employees, has a considerable impact on a country's growth. Innovation is an effective approach for firms to achieve growth. In this study, we propose that the phase of formulating growth guidelines, which include three factors: growth objectives, scope, and directions for growth, should be establish before the phase of implementing the innovation process. A new scope framework is constructed and a method for evaluating the consistency of the growth guidelines is presented. The method is applied to Japanese mechanical engineering SMEs that have achieved growth through innovation, and the applicability of the framework and the consistency of the growth guidelines are confirmed. This study provides an idea of growth guidelines that can be used to guide decision making in implementing the innovation process.

Floods are one of the most common and damaging natural disasters, claiming lives, and causing significant economic damage. Urbanization can increase the risk of flooding due to increased water runoff and volume. This study focuses on a flood vulnerability assessment approach as a planning tool by combining the Flood Vulnerability Index (FVI) with variables available in urban development areas. This index was created by combining the variables of three components: exposure, susceptibility, and resilience. FVI is a critical element in risk management and flood damage assessment. Vulnerability is described in FVI research as the amount of damage that can be predicted under conditions of exposure, susceptibility, and resilience. Vulnerability studies frequently use an indicator-based vulnerability assessment to estimate the complexity and degree of risk. FVI reflects the vulnerability of urban areas. Secondary data were used to obtain variables for the social and economic components. A quantitative method was used to calculate the correlation of each variable with flooding via the Statistical Package for the Social Sciences (SPSS). The indicators are categorized as exposure, susceptibility, and resilience, and these indices were created using normalization, weighting, and aggregation of the indicators. To determine the flood vulnerability in Selangor, a small number of indicators were selected to quantitatively assess the flood risk in Selangor. Based on calculated FVI, the vulnerability of the districts in Selangor has been ranked and categorized from high to very low. The result shows Gombak and Klang are the most vulnerable districts in Selangor to flooding because of their high exposure to flooding. The results of this study could serve as a reference tool for future flood risk mitigation efforts in Selangor.

Building energy analysis is rarely carried out due to the complexity of building shape and materials. On the other hand, the urgency of environmentally friendly construction is increasing through the vision of the SDGs and Architecture 2030. The development of BIM technology is expected to provide accurate estimates of building energy consumption for projects undertaken, as well as recommendations for alternative designs and specifications to increase the energy efficiency of a building. The use of BIM technology for energy analysis during building design helps to implement green building sustainable design based on the analysis of BIM energy simulation software. Data of three-dimensional BIM model with the attributes of materials, project schedule and location are used in building energy consumption simulation analysis. Several scenarios of different materials and layout are carried out to determine the most efficient scenario for energy consumption and followed by its cost estimation. The results of this study are expected to be able to provide the energy value that can be saved through predetermined scenarios as well as the value of the costs required to run a more energy-friendly design scenario in a comprehensive manner.

Published: September 2024

The integration of dynamic simulation analysis has become widespread in general-purpose software, providing enhanced capabilities. However, accurately tracking deformations based on complete equilibrium solutions remains a significant challenge in problems characterized by strong geometric nonlinearity. This study examines the accuracy of the combined Newmark β method and Tangent stiffness method in dynamic analysis with ultra large displacements and evaluates the utility of Rayleigh proportional damping in numerical simulations compared to experimental models. An experimental model of a slender steel plate undergoing free vibrations after being released from a deformed state was created. Video footage capturing the deformation histories was compared to computational simulations to verify accuracy. The study also examines the appropriate values of the damping ratio (ζ) and the Newmark β value in the simulations. The results indicate that adjusting various damping ratio and a β value of 1/2 yield more realistic simulations with longer conservation of mechanical energy. The findings suggest that incorporating numerical damping into actual damping settings can achieve a more realistic simulation of dynamic behaviour with ultra-large displacements. Furthermore, experiments and analyses were performed to correct natural frequency by changing Young’s modulus, which is a key factor influencing natural frequencies, with observed correlations to plate thickness, setting the stage for further research under varied conditions to develop a more rational methodology for structural analysis.

A poor understanding of peat behavior has introduced several engineering problems including differential settlements or slides which greatly impact society. Problematic characteristics of peat including a high moisture content and the presence of fresh fibers, cause a significant challenge in obtaining high-quality samples for laboratory-based investigation. Therefore, the application of in-situ geophysical methods is sought to mitigate these problems. The dynamic properties of a peat deposit in West Malaysia are described in this study. The Multichannel Analysis of Surface Waves (MASW) was conducted at six different locations. These peat soils had considerably different characteristics due to the different natures of decomposed materials. The samples obtained from the five locations had organic contents of 66.5 to 97.1%, water contents of 447 to 964%, and fiber content between 22.1 and 75.2%. Based on Von Post classification, the peat type ranged from H3 (fibrous) to H8 (amorphous). Shear wave velocity (Vs) and maximum shear modulus (Gmax) are presented, and their dependence on variables such as moisture content, organic content, fiber content, specific gravity and bulk density are illustrated. The general trend shows an increase in Vs and Gmaxwith decreasing moisture, organic and fiber content of peat soil. The difference in the degree of humification did not result in significant differences in Vs and Gmax obtained. The results showed that the value of Vs and Gmax ranged from 24.0 to 67.1m/s and 0.40 to 7.06 MPa respectively. Correlation between the index and dynamic properties peat shows that the Vs and Gmax increase as the moisture, organic and fiber content decreases. Successful determination of in-situ Vs and Gmax on peat soil minimized the potential of underestimation due to sample disturbance and provide a sustainable, rapid and economic method.

Landfill leachate has a high concentration of ammonia, making it a harmful pollutant for both surface and groundwater. One of the most favoured methods for removing ammonia from leachate is aeration, as it has been proven to remove a significant amount of ammonia in the most efficient and economical way. The effect of operational variables on ammonia removal efficiency by aeration was investigated in the current study by applying Response Surface Methodology (RSM) approach. Three operating parameters such as airflow rate, aeration time and lime dosage were investigated to achieve the optimization of ammonia removal. The optimal parameters for a favourable reaction of ammonia-nitrogen (NH3N) removal were found to be 6 L/min airflow, 90 minutes aeration time, and a lime dosage of 6 g/L. At these ideal conditions, Quadratic RSM predicted a maximum NH3N removal of 98.0%, which has been validated by the experiment and successfully removed 97.6%. The finding also showed that airflow rate and aeration time were more significant than lime dosage for NH3N removal. Due to increased contact time between air and liquid, regardless of the amount of lime used, increasing the aeration period ammonia removal efficiency. Considering the influential factors, determining the optimum condition for ammonia removal by aeration will explain the potential interferences that may inhibit the efficient recovery of NH3N. Hence, aeration is a promising approach for ammonia removal from landfill leachate.

Flood disasters can occur unexpectedly, causing significant damage to homes or office buildings and their contents. Moreover, they pose a serious threat to health, and the recovery process can take 3-7 days. As a result, many flood victims face challenges in accessing clean water for essential needs, which can be especially difficult in urgent situations. There is a pressing need for solutions that can improve and support flood victims. This project aims to address this need by proposing a system for recycling floodwater. It also seeks to highlight the potential usefulness of floodwater for various purposes. The project utilizes the ADDIE model to develop a tool, specifically a smart indicator called ArduPoSt, which utilizes Arduino technology in conjunction with potassium alum and river stone to monitor and enhance the quality of floodwater. The product was tested with two samples, potassium alum with and without river stone, to gauge the accuracy of water turbidity measurement. The results demonstrated thatwater turbidity measurement was more accurate and faster when river stones were included. This product is designed to be flexible and valuable for addressing urgent needs of flood victims. Additionally, there are plans to further enhance its usability through the development of a more interactive design with mobile applications in future iterations.

Changes in river flow have become a natural cycle of the river. The Lusi River has problems with meanders due to sediment transport, which is difficult to control. A combination of GIS with RS and HEC-RAS simulation was used to monitor river flow. The water monitoring method utilizes four water indices: NDWI, MNDWI, ANDWI, and SAVI, while the MPM-Toffaleti method is used for simulation. By combining the four methods, accuracy values of 0.68 to 0.92 and precision levels of 0.60 to 0.93 were obtained. MNDWI obtained quite high results compared to other indices. The results showed that the Lusi Riverexperienced quite extreme flow changes. Two flow cuts occurred. Considerable erosion occurred from 2003 to 2013 with a total lost area of 0.1943 km2, while from 2013 to 2023, there was erosion of 0.1177 km2. The HEC-RAS simulation of the Lusi River experienced erosion of 60 to 70.4 percent of the length of the stream. Changes in the riverbed in 2013 were found to be -1.1 ± 2.03 m, and then in 2023, the range of changes in the riverbed was -2.69 ± 1.29 m. Based on the results of the index and simulation of the Lusi River experiencing erosion in the flow, the level of erosion has increased every period.

Since 2015-2016, when the European continent underwent an unprecedented peak in demands for asylum, grassroots football clubs have been at the forefront in offering refugees a place of first contact with their new host society. The perception of the impact that their initiatives may have had on their target population is however almost exclusively based on some widely shared basic assumptions drawn from anecdotal evidence and, marginally, on a small body of literature grounded in local studies of ethnographic nature. The article recapitulates the inception and implementation of an original mixed-method research survey within the framework of two successive practice-oriented projects led by civil society actors and supported by the ERASMUS+ Sport funding scheme. Following a literature review, it describes the survey design, analyses the findings, and discusses the added value and limits of this research focused on the principal target group of volunteers in European grassroots football.

The purpose of the research is to study the acute oral and dermal toxicity of a veterinary drug (fipronil, pyriproxyfen) in mice and rats.Materials and methods. The studies were performed according to the Methodical Guidelines of the State Pharmacological Committee in the vivarium of the VNIIP – FSC VIEV from February to April 2021. White outbred male mice and male rats were used as a test system to study toxicological characteristics of the study drug. The veterinary drug Insektal Shampoo is a topical solution that contains fipronil and pyriproxyfen as active ingredients. In studying the acute oral toxicity and acute dermal toxicity of the study drug on laboratory animals, established procedures were used.Results and discussion. The median lethal dose (LD50) was 12 500 (11,532÷13,468) mg/kg when administered to the white male mice intragastrically as per Miller-Tainter method. According to the generally accepted hygiene classification, the drug was classified as hazard class 4 according to GOST 12.1.007-76. For the white male rats, LD50 was more than 20,800 mg/ kg (hazard class 4). When applied to intact rat skin, LD50 was more than 10 400 mg/kg, which corresponds to hazard class 4.

The article examines various approaches to defining personal resilience, which is an important indicator of an individual's successful adaptation to stressful situations and crises. Resilience is understood as the ability of a person not only to maintain their integrity in difficult conditions but also to use these circumstances for personal growth and development. In conditions of uncertainty, crises, and stressful situations, personal resilience serves as a protective resource that allows individuals to maintain mental health and adaptive capabilities. The article focuses on the analysis of external and internal factors of resilience, particularly such resources as faith, hope, self-acceptance, acceptance of others, patience, and the ability to establish positive relationships. Personal resilience also includes the individual's ability to exhibit cognitive flexibility, manifested in the ability to adjust plans and expectations, adapting them to new conditions. The development of resilience can have both a protective and proactive nature, allowing a person not only to cope with difficulties but also to discover new opportunities for personal growth. Psychological studies suggest that the development of such resources as internal motivation, self-regulation, and self-acceptance plays a crucial role in enhancing personal resilience in the face of external threats and uncertainty. The research also highlights that important coping strategies that help overcome stress include positive reappraisal and problem-solving planning. These strategies not only help reduce anxiety levels but also effectively contribute to personal development. Less effective strategies, according to the studies, are those aimed at seeking external support or avoiding responsibility, as they do not contribute to internal resilience. Thus, personal resilience is a multifaceted phenomenon that encompasses a set of psychological resources and adaptive strategies that help individuals maintain balance and emotional well-being during crises. Research into these mechanisms is essential for the development of psychological support programs and interventions aimed at strengthening resilience and the ability to thrive in challenging life circumstances.
