An evaluation of the operational efficiency of pizza restaurants in Zimbabwe
Authors: Mukucha P.
Published: September 2022

The study sought to test the industry wide claim in the fast-food restaurant industry that they deliver pizza within 10 minutes of waiting. The study further sought to assess the extent to which the actual waiting period for pizza differs from the perceived waiting time. A sample of 500 pizza transactions had their order cycle time measured, and the corresponding perceived waiting time was also recorded from the surveyed respondents who had initiated the transactions. The study revealed that there are statistically significant differences between the prescribed standard waiting time and actual waiting time, and between the actual waiting time and perceived waiting time. This study therefore recommends that restaurateurs in the pizza industry must assess their human and equipment resources in order to reduce the variances in lead times. They must as well provide various materials and activities that occupy customers in order to reduce the perceived waiting time.

Published: September 2022

Outbound logistics is one of the prime business functions that are pillars in customer value delivery. In this study the investigation sought to determine the influence of outbound logistics on economic utility: form utility, place utility, time utility, and possession utility. A Sample of 300 respondents was surveyed from the residents of Bindura urban area using convenience sampling method. ANOVA and Tukey’s HSD post hoc multiple comparisons tests were used for hypotheses testing. The study revealed that outbound logistics for bread has a significant effect on all the forms of economic utility save for possession utility. It was therefore recommended that bakeries must deliver their bread through the use of tuck-shops, convenience stores and supermarkets with their order of importance in order to enhance the perceived value in the form of economic utility that accrues to the customers who buy bread.
Migration dynamics and the devolution agenda in Matabeleland South Province of Zimbabwe
Authors: Mtombeni N. , Matiza V.M.
Published: September 2022

Economic challenges in Zimbabwe have seen most people relocating to different countries in a bid to earn a decent living. These movements are done at all levels, whether learned or general/ domestic workers. In doing so, a lot of brain drain is witnessed where many technical and expert personal are no longer offering their services to their home countries but elsewhere. The government of Zimbabwe has come up with a statutory instrument to grow the Zimbabwean economy at Provincial level so as to become an upper middle economy by 2030. With this challenge at hand, migration of these people has a lot of implication on the government’s devolution agenda as the local people are moving away from developing their area.  Against this backdrop, the paper seeks to bring out migration dynamics in Matabeleland South Province which may hinder government efforts in achieving the agenda in the Province. Most of the people in the province are a source of cheap labour in the neighbouring South Africa and possibly Botswana. Using qualitative research methods, the researchers purposively sampled some families in Gwanda and conveniently selected some government departments to establish the purpose and impact of the devolution program. Through some interviews carried out, the research established that many people especially youths in the Province migrate to South Africa as cheap labour and that impacts negatively on the devolution agenda and the vision 2030 in the Province. As a result the researchers therefore recommend that the government of Zimbabwe should put in place stringent measures at the boarder places so that the easy flow of human traffic as boarder jumpers is curbed.

Nitekim çalışmanın sonucunda dilin ses düzeyindeki cinsiyet göstergelerinin genellikle kadın ve erkek biyolojik ve fizyolojik altyapısından kaynaklanan cinsiyet farklılıklarına dayandığı; dildeki cinsiyet göstergelerini içeren gramer kategorilerinin toplumun diyalektik dünya algılayışı üzerine kuruldukları; dilin leksik düzeyinin, toplumsal cinsiyet göstergelerini anlamsal çağrışımlarında içermesi, leksik boyutun üstün cinsiyet işaretli düzey üzerinde kurgulandığı tespit edilmiştir.
Towards Tight Differential Bounds of Ascon
Authors: Makarim Rusydi H. , Rohit Raghvendra
Published: September 2022

Being one of the winners of the CAESAR competition and a finalist of the ongoing NIST lightweight cryptography competition, the authenticated encryption with associated data algorithm Ascon has withstood extensive security evaluation. Despite the substantial cryptanalysis, the tightness on Ascon’s differential bounds is still not well-understood until very recently, at ToSC 2022, Erlacher et al. have proven lower bounds (not tight) on the number of differential and linear active Sboxes for 4 and 6 rounds. However, a tight bound for the minimum number of active Sboxes for 4 − 6 rounds is still not known.In this paper, we take a step towards solving the above tightness problem by efficiently utilizing both Satisfiability Modulo Theories (SMT) and Mixed Integer Linear Programming (MILP) based automated tools. Our first major contribution (using SMT) is the set of all valid configurations of active Sboxes (for e.g., 1, 3 and 11 active Sboxes at round 0, 1 and 2, respectively) up to 22 active Sboxes and partial sets for 23 to 32 active Sboxes for 3-round differential trails. We then prove that the weight (differential probability) of any 3-round differential trail is at least 40 by finding the minimum weights (using MILP) corresponding to each configuration till 19 active Sboxes. As a second contribution, for 4 rounds, we provide several necessary conditions (by extending 3 round trails) which may result in a differential trail with at most 44 active Sboxes. We find 5 new configurations for 44 active Sboxes and show that in total there are 9289 cases to check for feasibility in order to obtain the actual lower bound for 4 rounds. We also provide an estimate of the time complexity to solve these cases. Our third main contribution is the improvement in the 7-year old upper bound on active Sboxes for 4 and 5 rounds from 44 to 43 and from 78 to 72, respectively. Moreover, as a direct application of our approach, we find new 4-round linear trails with 43 active Sboxes and also a 5-round linear trail with squared correlation 2−184 while the previous best known linear trail has squared correlation 2−186. Finally, we provide the implementations of our SMT and MILP models, and actual trails to verify the correctness of results.

Authors: Franciosi Ana Paula , Testa Saulo , Both Jorge
Published: September 2022

Ao considerar a atividade docente é possível analisar que no cotidiano dos professores estão presentes fatores estressores referentes à reestruturação das atividades profissionais; a alta exigência do mercado de trabalho e alta competitividade podem levar ao desencadeamento de doenças relacionadas ao trabalho. Assim, o objetivo deste estudo foi avaliar os níveis de Síndrome de Burnout de professores de Educação Física da Educação Básica conforme as variáveis sociodemográficas. A amostra contou com 59 professores de Educação Física que atuavam na cidade de Arapongas (Paraná, Brasil) que possuíam vínculo empregatício com as redes de estadual e municipal de ensino. Para a coleta de dados os professores responderam dois questionários, sendo que o primeiro abordava as variáveis sociodemográficas, e o segundo foi a Escala de Caracterização do Burnout. Para a análise dos dados empregaram-se os testes: Prova U de Mann-Whitney e Kruskal-Wallis, adotado o nível de significância de 95% (p<0,05). Os resultados evidenciaram que os professores que não possuíam pluriemprego demonstraram maiores índices de Exaustão Emocional e os docentes com até 10 anos de docência possuíam maior índice de Desumanização, visto que a necessidade de complementação de renda em início de carreira, bem como a falta de estabilidade no ambiente laboral contribuem para que os docentes apresentem sentimento de afastamento, indiferença distanciamento nos relacionamentos interpessoais trabalhistas.

Avaliação do tratamento de água por filtração rápida descendente com uso de areia de britagem – remoção de turbidez e de indicadores bacterianos
Authors:   , Cornélio Luana Alves dos Santos
Published: September 2022

O objetivo deste trabalho foi avaliar o tratamento de água para consumo humano por meio da filtração rápida descendente com uso de areia de britagem em diferentes condições de coagulação e qualidade da água afluente aos filtros. Ensaios em escala piloto foram realizados em duas unidades de filtração: uma com areia de britagem e a outra, como unidade de controle, com areia natural de rio (convencional). Ambos os leitos filtrantes foram preparados com granulometria e profundidade de acordo com o especificado em norma da ABNT para filtração rápida com areia natural. Os filtros foram operados simultaneamente com taxas de filtração de 180, 270 e 360 m 3 m -2 d -1 . Ao longo do período de fevereiro de 2019 a março de 2020 foram monitoradas 22 carreiras de filtração, as quais foram caracterizadas em termos de: (i) duração das carreiras; (ii) evolução das perdas de carga; (iii) remoção de turbidez; (iv) índices de filtrabilidade; e (v) remoção de protozoários e bactérias por meio do uso de indicadores microbiológicos. Além disso, foi avaliada a influência do potencial zeta da água decantada no desempenho das carreiras de filtração. Em geral, o filtro de areia de britagem teve desempenho análogo ao filtro de areia convencional em termos de duração da carreira de filtração, perda de carga e turbidez da água filtrada, mesmo em condições operacionais desfavoráveis: turbidez afluente elevada, eventos de floração e taxa de filtração elevada. No período chuvoso, as carreiras de filtração foram mais longas que as do período de estiagem. Em relação a qualidade da água filtrada, os filtros produziram água filtrada com turbidez inferior a 0,50 uT durante a maior parte do tempo de operação. Além disso, os filtros comportaram-se de modo similar na remoção de microrganismos indicadores. Conclui-se que o uso de areia de britagem em filtros rápidos para o tratamento de água para consumo humano é viável como alternativa aos filtros de areia natural de rio, sem desvantagens em termos operacionais e de remoção de turbidez e de microrganismos. Palavras-chave: Tratamento da água. Filtração rápida. Meio filtrante. Areia de britagem. Indicadores microbiológicos.
Método TRS: Uma proposta para avaliar a tendência em produtos cartográficos por meio da análise em feições lineares
Authors:   , Zanetti Juliette
Published: September 2022

A utilização de dados tendenciosos em um banco de dados espaciais pode gerar produtos que não condizem com a realidade de campo. A análise de erros sistemáticos em uma base de dados espaciais permite propor ações que possam eliminar ou mitigar esses erros. Este passo é fundamental para garantir a qualidade do produto cartográfico. No entanto, poucos são os métodos para detecção de tendência em feições lineares. O presente trabalho propõe a avaliação de métodos de tendência a partir de feições lineares existentes na literatura, além de desenvolver um novo método. Para isso, iniciou-se o estudo e aplicação de metodologias para análise da acurácia posicional por meio de feições lineares, como: Pontos Finais, Pontos Intermediários, Ponto Gerado, Influência do Vértice, Normalização do Buffer Duplo e Fator de Fuzziness; utilizando como base o padrão brasileiro de acurácia posicional, o Decreto nº. 89.817/1984, em conjunto com a ET-CQDG (DSG, 2016). Para a análise da tendência em produtos cartográficos a partir de feições lineares avaliou-se os métodos existentes na literatura, sendo eles: Fator de Bias, Buffer Duplo e Influência do Vértice. O resultado desta avaliação mostrou que os métodos não são efetivos para uma análise da tendência. Assim, propôs-se o método Translation, Rotation e Scale (TRS) para detecção de erros sistemáticos a partir da análise de translação, rotação e escala em produtos cartográficos, utilizando-se das técnicas de estatísticas e análise vetorial. Os resultados obtidos pelo método proposto apresentaram resultados satisfatórios quando comparados com a metodologia tradicional (por pontos), comprovando assim a eficiência para a análise de tendência em dados cartográficos utilizando feições lineares. Palavras-chave: Cartografia. Controle de Qualidade Cartográfica. Feição Linear. Erros Sistemáticos. Tendência.
Simulação computacional do comportamento estrutural de vigas celulares mistas de aço e concreto com perfil monossimétrico
Authors:   , Pereira Caio Lopes
Published: September 2022

Nas últimas duas décadas, tem-se observado em diversos países um ressurgimento do interesse pelos perfis de aço alveolares, devido às vantagens técnicas e arquitetônicas que eles oferecem em relação aos perfis I de alma cheia. Este fenômeno se dá numa época em que ocorre uma grande difusão dos sistemas de piso misto de aço e concreto, hoje largamente utilizados no contexto da construção civil, por suas vantagens estruturais e construtivas em relação a outras soluções estruturais. Nos últimos anos, tem crescido o interesse pelo uso de vigas celulares mistas, incluindo a alternativa com perfil monossimétrico. Como a fabricação de vigas celulares já envolve processos de corte e solda, torna-se prática a montagem de perfis monossimétricos, onde o tê mais robusto é disposto na parte inferior da seção e o mais esbelto na parte superior, já que esta última fica solicitada por esforços de menor magnitude do que a metade inferior. Dada a escassez de estudos sobre o assunto, o objetivo deste trabalho é a avaliação do comportamento estrutural de vigas mistas celulares com perfil monossimétrico e do comportamento estrutural de vigas celulares monossimétricas quanto à flambagem do montante de alma, por meio de simulação numérica usando o Método dos Elementos Finitos, considerando análise não-linear geométrica e de material. A modelagem numérica foi validada com resultados experimentais disponíveis na literatura. A partir dos resultados numéricos obtidos, propõe-se uma adaptação para uma formulação de cálculo existente, destinada a perfis celulares duplamente simétricos, que a generaliza para vigas mistas celulares com perfil monossimétrico ou duplamente simétrico. Por fim, é apresentada uma análise do rendimento estrutural de vigas celulares mistas com perfil monossimétrico em relação a vigas similares com perfil duplamente simétrico. Palavras-chave: Estruturas de aço. Vigas celulares. Vigas mistas. Perfil monossimétrico. Flambagem do montante de alma.

Authors: Kryvenko A. I. , Martkoplishvili M. M.
Published: September 2022

Purpose. To establish the peculiarities of the photosynthetic parameters formation of corn crops depending on agro-technological practices in the South-Steppe region of Ukraine.

Methods. Field and laboratory research methods and statistical methods, such as descriptive statistics and analysis of variance.

Results. The leaf area during the growing season of corn increased and was the maximum in the flowering phase of the corn cob in comparison with other phases of growth and development and averaged 37.35 thousand m2/ha. However, the best results (39.52 thousand m2/ha) were with the use of the destructor StimOrganic (2 l/ha), urease inhibitor (nitrification) Stabiluren 30 and foliar feeding Aminomax and Aidamin complex fertilizer (40.23 thousand m2/ha). It was also found that the formation of dry matter was influenced by experimental factors. Thus, in general, during the growing season of corn for the use of the destructor StimOrganic (2 l/ha) in combination with urease inhibitor (nitrification) Stabiluren 30 and foliar feeding Aminomax (1 l/ha) accumulated yield was 9.79 t/ha, while with Aidamin complex fertilizer (2 l/ha) the yield was 10.11 t/ha of dry matter (to compare, 7.51 t/ha in the control version). The maximum photosynthetic potential of the experiment was identified in the interphase period from the formation of 15 leaves to flowering cob. It was found that the best values of photosynthetic potential were on the options of using the destructor StimOrganic (2 l/ha) in combination with urease inhibitor (nitrification) Stabiluren 30 and foliar feeding Aminomax (1 l/ha), 0.99 thousand m2/ha, and in the treatment with Aidamin complex fertilizer (2 l/ha), 1.00 thousand m2/ha.

Conclusions. Activation of growth processes caused by the use of foliar fertilization contributed to the formation of the best indicators of net productivity of photosynthesis in the interphase period from the formation of 15 leaves to flowering cobs. But in the phase from milk ripeness to full ripeness of corn grain against the background, the best values obtained by the action of urease inhibitor (nitrification) Stabiluren 30, were leveled up by the the effect of foliar feeding.
Features of sterilization of various explants of rhododendrons (Rhododendron L.) and their introduction in vitro
Authors: Voitovska V. I. , Ukrainets O. A. , Osipov M. Yu. , Maslovata S. A.
Published: September 2022

Purpose. To establish the influence of sterilization conditions and the type of explants for obtaining aseptic culture of representatives of the genus Rhododendron (L.).

Methods. Biotechnological, laboratory, analytical, statistical.

Results. It was found that for 70 % of the concentration of the soap solution and exposure for 10–15 minutes with three washes, it is possible to obtain additional sterile seeds up to 33 %, and seedlings 29 %. The most effective treatment was with a concentration of primary sterilizer of 50 %, which provided additional sterile seeds of 37 % and seedlings – 31 %. The worst was a solution of primary sterilizer 20% for which sterile seeds amounted for 15 % and seedlings for 8 %. At a concentration of 35 %, and exposition for up to 10 minutes it is possible to reach seed sterility of 78 % and seedlings of 65 %, of which viable seeds 67 % and viable seedlings 57 %, which was one of the best results of the studied treatments. The lowest rates of sterile explants were observed in the treatments with hydrogen peroxide (H2O2). Seeds were only 23 % sterile and seedlings 12 %. Seed viability was up to 14 %, and seedlings up to 34 %. The results of the studies indicate that with the combined use of 35 % Bilyzna and 50 % Bradofen, it is possible to obtain sterile seeds from 83 to 95 % and seedlings from 83 to 91 %. In addition, viable explants in this combination were founding in seeds from 76 to 85 %, and in seedlings from 67 to 82 %. The most effective combination is 35 % Bilyzna and 50 % Bradofen for 10 minutes of exposure. Sterility was 94 % in seeds and 90 % in seedlings, viability: 83 and 80 %, respectively. It is worth noting the lack of necrotic tissue in seedlings.

Conclusions. Regardless of the concentration, the most optimal exposure was 10–15 minutes. Depending on the type of explant and the use of the primary sterilizer, a higher percentage of sterile seeds was obtained compared to seedlings. The mercury dichloride concentration of 0.4 % and 0.2 % provided a low percentage of viable explants for both seeds and seedlings. In the latter, its use led to partial burns of the leaf surface. Therefore, the use of mercury dichloride 0.4 % and 0.2 % was not appropriate for sterilization of plant material of the genus Rhododendron (L.). The most effective way to sterilize the seeds of the genus Rhododendron (L.) is to use a 35% solution of Bilyzna for 10 minutes. Seedlings should be sterilized for 8 minutes, and the increase leads to a higher percentage of necrotic material.

Purpose. Establish the content of chemical compounds in sesame seeds depending on varietal characteristics.

Methods. Laboratory, analytical, statistical.

Results. The fat content and its quality is the main indicator characterizing the value of oil. In oilseeds and in particular in sesame, it varies widely depending on the variety, area and growing conditions, the degree of maturity of the seeds and other indicators. It was found that the protein content in sesame seeds, depending on the varietal characteristics, was from 20.53 to 20.11 g. The lowest carbohydrate content was in variety ‘Kadet’ (0.13 g), and the highest was in ‘Boiaryn’ and ‘Ilona’ (0.17 g). Dietary fiber content in ‘Ilona’ was 12.5 g and was dominated by other varieties, such as ‘Boiaryn’ (0.3 g), ‘Husar’ (0.7 g), ‘Kadet’ (0.9 g). Weather conditions significantly affected the accumulation of water by seeds. Thus, over the years of research, this indicator averaged from 3.95 to 3.77 g. The high content of calcium was in variety ‘Kadet’ (376 mg), slightly lower was in variety ‘Ilona’ (374 mg), ‘Husar’ (372 mg) and low in ‘Boiaryn’ (367 mg).

Conclusions. Soil and climatic conditions significantly affected the accumulation of water by seeds. Thus, over the years of research, this indicator averaged from 3.95 to 3.77 g. The high content of K was in variety ‘Kadet’ (376 mg), slightly lower in ‘Ilona’ (374 mg), ‘Husar’ (372 mg) and low in ‘Boiaryn’ (367 mg). According to the calcium (Ca) content, it was determined that only ‘Kadet’ variety contained 62 mg, while in all other varieties its content was lower 60 mg. The quantitative content of Mg differed in the studied varieties of sesame as following: ‘Kadet’ 347 mg, ‘Ilona’ 345 mg, and ‘Husar’ 344 mg. Slightly lower indicators were in variety ‘Boiaryn’ (341 mg). According to the studies, it was found that the variety ‘Kadet’ (47 mg) insignificantly dominated the studied varieties in terms of sodium content by 0.2 mg. The S content in sesame seeds was as following: in ‘Kadet’ 204.8 mg, ‘Husar’ 204.3 mg, ‘Ilona’ 203.6 mg, and ‘Boiaryn’ 203.1 mg. The quantitative content of P in the studied sesame varieties was the highest in ‘Kadet’ reaching 672 mg, which is 0.2 mg less than in ‘Husar’, 6.0 mg less than in ‘Ilona’, and 18 mg less than in ‘Boiaryn’. Thus, the content of macronutrients in sesame seeds was the highest in variety ‘Kadet’.

Authors: Liubych V. V.
Published: September 2022

Purpose. To study the question of the baking properties of spelt grain depending on the variety and line.

Methods. Laboratory, mathematical and statistical, physicochemical.

Results. The article presents the results of studying of gluten deformation index, the flour strength on the stability of the dough ball in water, the falling number and the gas retaining quality of spelt flour. Of the 16 studied varieties and lines of spelt wheat, four had satisfactorily weak gluten, and the rest were unsatisfactorily weak. Close to the indicator of satisfactorily weak gluten were the grain of the ‘Shvedska 1’ variety (101 units) and the LPP 3132 line (101 units). The NAK34/12-2 line had a very high flour strength, with an index of 248 min. Indicators of 121, 129 and 132 min were observed, respectively, in the ‘Schwabenkorn’ variety and LPP 3117, P 3 lines, which were characterized by a high flour strength. The average values had LPP 1224, LPP 3373, LPP 3132 lines and the ‘Zoria Ukrainy’ spelt variety, the indicators of which varied from 62 to 97 min. The low flour strength of the rest of the studied numbers was 40–57 min, which is less than the standard by 41–59 %. The maximum value of the gas retaining quality of dough was after 90 minutes of fermentation. Thus, the very high gas forming quality was found in the ‘Zoria Ukrainy’ variety and LPP 3132, NAK34/12-2 lines. High value (450 cm3/100 g) was in the NSS 6/01 line. Average values (404–420 cm3/100 g) were observed in seven lines. The ‘Shvedska 1’ and LPP 3373, as well as TV 1100 lines had a gas retaining quality of 369 and 348 cm3/100 g, respectively. The lowest fermentation time (287 and 321 cm3/100 g) was in the LPP 1304 and LPP 1221 lines. However, after fermentation of the dough for 120 min in the NAK34/12-2-line gas retaining quality was the highest and amounted to 513 cm3/100 g.

Conclusions. The gluten deformation index of varieties and lines of spelt varies from satisfactorily weak (97 units) to unsatisfactorily weak (116 units). The falling number is from 389 to 416 s, which indicates low amylase activity. The baking properties of spelt grain differ significantly from soft wheat, as the maximum gas retaining quality of spelt wheat flour dough occurs after 60–90 min of fermentation. After that it decreases rapidly. The dough obtained from ‘Zoria Ukrainy’ flour, NSS 6/01 and NAK34/12-2 line has the highest stability during fermentation.
Efficiency of a chemical weed control system for winter wheat
Authors: Cherniak M. O.
Published: September 2022

Purpose. To study the effectiveness of chemical weed control for winter wheat crops with the use of formulations based on sulfonylureas.

Methods. Field and laboratory.

Results. The use of Logran 75WG formulation in autumn allowed to reach weed control efficiency at the level of 71.2–87.2 % for use in the BBCH 10–13 development stage of wheat plants and 67.0–83.2 % for application in the BBCH 22–25 stage. However, herbicide Logran 75 WG at a high application rate (15 g/ha) allowed to effectively control such species as Chenopodium album, Polygonum convolvulus, Persicaria maculosa, Viola avrensis, Sinapis avrensis and Solanum nigrum in the BBCH 10–13 development stage of winter wheat and similar species in the BBCH 22–25 stage with a destruction efficiency of 89.0–100 %. Autumn application of herbicide PIK 75 WG in the BBCH 7–9 stage allowed to effectively control dicotyledonous weeds due to the soil action of the formulation. Thus, at the application rate of 20 g/ha, the overall efficiency of the formulation was 88.2 %, but for the application of 30 g/ha it was 96.7%. It is investigated that the use of Logran 75 WG in spring allowed to obtain weed control efficiency at the level of 60.9–77.2 % for use in the development stage of wheat plants BBCH 27–29 and 53.5–69.8 % for application in the BBCH 30–35 stage. Spring application of herbicide PIK 75 WG in the BBCH 25–26 stage allowed to effectively control dicotyledonous weeds due to long-term soil action of the formulation. Thus, at the application rate of 20 g/ha, the overall efficiency of the formulation was 75.1 %, but for the application of 30 g/ha it was 90.9 %.

Conclusions. It was found that spring application of herbicides to control weeds in winter wheat crops was less efficient, since perennial species had time to form a strong root system, which is resistant to the action of the formulation based on sulfonylureas. Wintering weed species continue their vegetation. Seeds of such species as Polygonum spp., Thlapsi avrense, Viola avrensis, Galium aparine, Sinapis avrensis, and others germinate in the early stages.
Youth unemployment in the European Union and transition period - from education to the labour market
Authors: Pkhakadze Tamar
Published: September 2022

The difference between youth and adult unemployment can be based on the high-level job mobility caused by the globalisation process, as well as the higher possibility of passiveness among the younger generation. The inactivity rate is quite diverse in different countries and is directly linked to youth unemployment. To compare adult and youth inactivity in the European Union, youth perform at a four times higher rate than the adult population. Higher inactivity usually has a direct link to entering into formal education. The transition process in this chapter describes the period from educational institutions to a stable working position. The transition period generally reflects the processes itself and how young people enter the labour market, along with how entry to the labour market is regulated and what the general consequences are for young job-seekers during this time. During the transition period, individual resources and the background of the person play an essential role while also coming with some consequences and barriers.

Published: September 2022

Rather than materialistic gain and possession, personality development is more of a process of growing human capabilities. Personality development is recognized as a vital component of corporate success, and it extends beyond the human realm. Especially freshly recruited engineers have to deal with challenging situations almost every day. Adaptability and strong interpersonal skills are essential soft skills for engineering students to cope with the strenuous/high-pressure work environment. The Audit courses can help in the holistic development of engineering students. These are introduced in the curriculum by AICTE in order to help students develop their personality, improve communication skills and learn about corporate grooming, for all branches of engineering. Audit courses focus across multidisciplinary domains and deliver holistic education with flexibility of subjects. The objective is to groom innovative minds into resilient personalities who can sustain and adapt to rapidly changing industrial needs and technological advancements. The perspectives to propose the audit courses vary across disciplines for e.g. foreign languages, performing arts and personality development. In India given the diversity and regional languages, students coming from different backgrounds need grooming in soft skills to back up their technical skills. Enhancement of personality can take place through different audit courses in a stress-free environment and enjoyable through different activities.
