Solution-oriented development of the sound environment in industrial workplaces

Objectives. Research literature has not given much evaluation to why the proposed noise control actions in workplaces are not being implemented. There are views of the different personnel groups in the workplace and the reasons why the possibilities for solutions have not been examined. Methods. The companies under study were a welding machine shop, an assembly plant, a heavy steel company and an art glass factory. Noise management was approached by combining the perspectives of technology, acoustics and occupational safety with the examination of sociocultural factors at the workplace level. Results. Noise was not well represented in occupational safety practices. The productivity aspect was strongly emphasized. The use of personal protective equipment created the illusion that everything possible has been done and noise controlled. Conclusion. The study developed a model in which experts in the field of acoustics and sociocultural researchers together evaluated the state and development needs of noise abatement. The results of the project show that successful noise control solutions require a process involving all staff in the workplace.

Left-behind places in central and eastern Europe—labour productivity aspect

Abstract In the 21st century, there have already been a series of economic downturns, particularly the Subprime Crisis 2007–2009 and the Covid-19 pandemic in 2020. All those events triggered changes in productivity, economic performance and structure. The main objective of this study is to identify the regions left behind in the Central and Eastern European (CEE) countries and to analyse the structural and productivity changes taking place within them. In our analysis, we aim to verify the research hypothesis that all left-behind regions in CEE have similar economic structures with a high share of agriculture. The research period covers the years from 2010 until 2020 using data from the Eurostat database. In the first phase of our analysis, we analysed employment, Gross Value Added (GVA) and productivity data for 11 CEE countries. Then, we analysed the Nomenclature of Territorial Units for Statistics at level 3 (NUTS3) regions, and Poland, which is a NUTS2 region. Left-behind regions are defined as those with low productivity and low growth rates. We provide a detailed analysis of the best and worst performing regions in terms of productivity for each country using productivity data and shift-share decomposition of productivity growth rate. Left-behind regions for each CEE country have been identified, and these are BG333, BG342, CZ080, EE004, HR023, HU332, LT027, LV005, PL72, RO216, RO312, SI032, SI035, SI038 and SK032. In our analysis, our hypothesis analysing the relationship between agriculture share in total employment and the productivity level of the region was not confirmed.

A systematic study to achieve cleaner and sustainable manufacturing process by using bio-degradable dielectrics

Inconel 600 is widely used in aeronautical and aerospace industry owing to its excellent mechanical, wear and corrosion characteristics. This high strength alloy requires a special machining environment which justifies the use of Electric Discharge Machining (EDM). However, low cutting rate, which accounts for the productivity aspect, and emission of toxic fumes generated by thermal breakdown of kerosene dielectric currently limit the use of EDM. Moreover, since EDM is an energy intensive machining process, industry has a stringent emphasis to make this process sustainable and eco-friendly. In this context, the potentiality of six bio-degradable dielectrics was comprehensively investigated here for the first time ever to achieve cleaner and sustainable production of Inconel 600. Each biodegradable dielectric was coupled to four electrode materials to find the best tool-dielectric combinations for the EDM processing of this Ni-based super alloy. The responses were defined considering the three key ingredients of sustainability: i.e. productivity (assessed in terms of material removal rate and tool wear ratio), quality (expressed in terms of surface finish and dimensional deviation) and power consumption (expressed in terms of specific energy consumption). Experimentation was performed with a full factorial design taking dielectric type and electrode material as input variables. The EDM configuration including amla oil as dielectric and brass electrode was the best in terms of maximum MRR (19.8 mm3/min), 560% better than the standard EDM configuration including the same brass tool and kerosene dielectric. The lowest surface roughness SR (quality aspect) was obtained by the EDM configuration including a brass electrode and the sunflower oil dielectric: surface quality improved by 30.6% with respect to standard EDM using the same electrode and kerosene dielectric. Considering the specific energy consumption, the EDM setup with brass electrode and amla oil dielectric was 6.6 times more efficient than standard EDM with the same electrode and kerosene dielectric. The combination of coconut dielectric and Cu electrode results in a 5.4 times lower tool wear ratio than the traditional dielectric. In terms of achieving a better dimensional control, graphite electrode is a preferred choice against olive oil dielectric. Based on the measured values for EDM responses, it was revealed that relative percentage of carbon dioxide emissions reduces by 83.95% if amla oil is used in comparison to the CO2 emissions noted for standard kerosene oil considering brass as electrode. Finally, an optimal combination of the best biodegradable dielectric fluid and electrode material to satisfy all performance indicators was proposed through MOGA technique. Experimental data were properly fitted by using artificial neural networks. The EDM setup with copper electrode and amla oil dielectric achieved the best global performance with respect to all responses.

PROSES PEMBENTUKAN DERIVASI DAN INFLEKSI PADA RUBRIK EDUKASI KOMPAS.COM

The word formation process is inseparable from the morphological process of affixation. The formation of verb word classes can be derived from verb, noun, adjective, and adverb word classes. This phenomenon causes morphological symptoms of derivation and inflection. Derivation is the process of forming new words that cause changes in lexical identity, while inflection does not change lexical identity. This study aims to obtain a description of the process of forming derivation words and forming inflected words on Kompas.com. Research using qualitative methods. The data and data sources used are online news Kompas.com, the January 2022 edition of the education rubric. The analysis technique used in analyzing the data uses the distribution method with the direct element division technique. The results of this study found words that experienced derivation and inflection with various kinds of forming affixes. Derivative and inflected affixes in Kompas.com consist of prefixes, suffixes, confixes and combinations of affixes. Initial prefixes or affixes are in the form of meN-, di-, ke-, ber-, ter, se-, and peN-; suffixes or final affixes consist of -an, -i, and -kan; confix affixes have forms of ke-an, penN-an, per-an, and beran; as well as combinations of affixes consisting of the forms of memper-/-kan, meN- -i, di-/-i, meN-/-kan, di-/-kan, diper-/-kan, and diper-/-i. The phenomenon of the affix meN- is an affix that forms an active verb, while the affix di- forms a passive verb. Also found ter- and ke-an affixes which are affixes forming anti-passive ergative verbs. Based on the productivity aspect, inflection is more productive than derivation.

Relationship between body weight and elevation in Leadbeater’s possum (

The body size of mammals is influenced by several evolutionary, morphological, physiological and ecological factors. Studies of body size can provide insight into the processes underlying observed variation in patterns of mammal morphology. We sought to determine if body weight in Leadbeater’s possum (Gymnobelideus leadbeateri) is related to environmental variables and/or sex. Using linear regression modelling, we quantified the influence on body weight of broadscale geographic variables such as latitude and elevation, site-level indicators of forest productivity (forest type, slope, aspect and topographic wetness) and an individual-level variable (sex). We found that body weight was significantly associated with elevation and sex, with individuals being heavier at higher elevations and males (on average) being heavier than females. Monitoring body weight changes over time within particular forest types will be valuable, given the variations in temperature and resource productivity throughout the range of Leadbeater’s possum that are likely to arise from climate change.

To study the productivity aspect of milkfed and HDDCF: A comparative study

Cooperative as formal associations came to be set up in India from 1904 mainly as credit societies, followed by non - credit societies from 1912. Cooperatives are based on the cooperative values of “self - help, self - responsibility, democracy and equality, equity and solidarity”. Modern dairy industry plays a vital role in maintaining and promoting the health of the people. The dairy cooperatives are one of the largest and most important of food industries. Earlier, the dairy farming was basically a domestic economic unit. It was carried out at the household level for producing milk for home consumption. Now the dairy industry has an important place among the agriculture industries of most countries. It has a strategic role in ensuring food and nutritional security, income and employment generation and in balancing in rural inequity. As per March 2010, 6 unions of VITA are operating in Haryana and 11 unions of VERKA are operating in Punjab. The purpose of study is to examine the productivity of MILKFED and HDDCF for the period 2005–06 to 2009–10. Further, the data has been analyzed with the help ofpercentages, compound growth rate, mean, ratio analysis. The study found that the MILKFED is better than HDDCF.

Alternative View of Unemployment Issue among Saudi Citizens - Automatization of Local Gas Stations as a Case Study

The primary objective of this paper is to propose an alternative solution for unemployment among Saudi youth. This paper seeks to address the problem of unemployment in Saudi Arabia from a different perspective: productivity aspect. Substantially, this paper proposes solutions for the Saudi youth unemployment problem by increasing the non-oil private sector's productivity. It evaluates the macroeconomic gains of the proposed solutions, such as the number of new jobs for Saudi citizens and additional value-added. The research's main hypothesis is that increasing the non-oil private sector's productivity would significantly reduce unemployment among Saudi citizens. There are two methodologies for evaluating the expected economic benefits of increasing productivity in local economic activities. The first methodology, which is the Saudization of local gas stations by transforming the local gas stations into self-service ones (with one cashier every 8 hours for each gas station), finds that there would be more than 28,000 new jobs with reasonable salaries (at least SAR 3000 instead of SAR 1000 for at least 5 low-skilled foreign laborers) for unemployed Saudi citizens, which are socially accepted and at no additional cost to the government. The second methodology uses Leontief’s IO model to estimate the macroeconomic effects of increasing productivity in the non-oil private sector. It finds that the Saudi gross domestic product (GDP) is expected to record an additional growth rate of around 2.7 percentage points (Note 1) and to create more than 96,000 sustainable jobs for Saudi citizens within the period from 2021 to 2025.

The Optimization of Alternating Current Electrospun PA 6 Solutions Using a Visual Analysis System.

The electrospinning process that produces fine nanofibrous materials have a major disadvantage in the area of productivity. However, alternating current (AC) electrospinning might help to solve the problem via the modification of high voltage signal. The aforementioned productivity aspect can be observed via a camera system that focuses on the jet creation area and that measures the average lifespan. The paper describes the optimization of polyamide 6 (PA 6) solutions and demonstrates the change in the behavior of the process following the addition of a minor dose of oxoacid. This addition served to convert the previously unspinnable (using AC) solution to a high-quality electrospinning solution. The visual analysis of the AC electrospinning of polymeric solutions using a high-speed camera and a programmable power source was chosen as the method for the evaluation of the quality of the process. The solutions were exposed to high voltage applying two types of AC signal, i.e., the sine wave and the step change. All the recordings presented in the paper contained two sets of data: firstly, camera recordings that showed the visual expression of electrospinning and, secondly, signal recordings that provided information on the data position in the signal function.

Key words: kerupuk kemplang agroindustry, marketing strategies, production performance

The Status of Laying Traits in Indigenous Chicken of Bangladesh: A Review

This paper covers the review of diversified performance of laying traits of Bangladeshi indigenous chicken in both in situ and ex situ including few global studies. Indigenous chicken constitutes about 80% of the total chicken population in Bangladesh and their different genotypes distribute throughout the country having distinct morphological and productive characteristics. The common native genotypes (usually non-descript or deshi) provide 35-45 eggs annually with 83-96% egg fertility and 75-88% hatchability in free range while better performance is observed in extensive system. Although Naked Neck and Hilly chicken genotypes perform superior but they are not available like common deshi. The genetic improvement of laying traits is a challenging work for the village chicken in Bangladesh, however, the planned breeding strategies along with improvement management system could enhance the activity. The results presented in this review would be a guideline for selection of indigenous chicken to improve further its productivity and conservation aspect. Thus, a conceptual breeding strategy is proposed here for the improvement of laying traits in village chicken in-situ as uncontrolled mating occurs there compared to ex-situ condition.

A Framework for Improving Software Reusability within Quality Constraints.(Dept.E)

In this paper seven of the most important issues in software systems development have been investigated. These issues address two aspects, namely: software development productivity and the final overall quality. For the productivity aspect, an approach has been devised relying on using scripts. Built as a result of an analyst-user collaboration, these scripts, upon interpretation, transform given user requirements into code. This prototyping approach, in addition to being rapid, involves the user in order to ensure his overall satisfaction with the final product. For the quality aspect, a two-layered repository of thoroughly tested and verified reusable software components has been built. The first layer contains the kernels to interpret the scripts. This is independent of the physical implementation of the functional components in the second layer. Using the repository, the care data manipulations of virtually any application can be automatically generated. Five applications covering five different domains have been designed and implemented to investigate the merits of the above described framework.
