Authors: Miran Sajjad , Tamoor Muhammad , Kiren Tayybah , Raza Faakhar , Hussain Muhammad Imtiaz , Kim Jun-Tae
Published: July 2022

This paper presents the optimal design of a photovoltaic (PV) drip irrigation system. Designing a PV system is based on calculated motor power, solar irradiance level and other meteorological parameters at a certain geographical location. Therefore, a simulation study of the designed PV system were performed by a PVGIS simulation tool. The PVGIS simulation tool analyzes the potential of power generation with optimal PV modules tilt angle and orientation on a monthly and annual basis, and an analysis of the overall shading situation (horizon) as well as the internal shading between the PV module rows. The selection of water pump and motor depends upon the depth of water table and desired discharge and head to operate the irrigation system. Furthermore, a locally developed Solar-Drip Simulation Tool (SoSiT) was used for load and supply optimization. Based on ambient temperature, solar irradiation and water requirements, SoSiT calculates net generation by a PV system and resultant water output of the irrigation system. The particular drip irrigation site has two zones; the maximum water requirement for zone 1 (row crop) is 50,918.40 Liters/day and for zone 2 (orchards) is 56,908.80 L/day. From PVGIS simulation results, the maximum daily energy production of the designed PV system was 6.48 kWh and monthly energy production was 201 kWh in the month of May. SoSiT results showed that the PV system fulfilled the required crop requirement by only using 28% of the potential water supply, and 72% of the potential water supply from a solar-powered pump was not used. This value is high, and it is recommended to grow more or different crops to utilize the fuel-free electricity from the PV system. The unit cost of PV-powered drip irrigation is USD 0.1013/kWh, which is 4.74% and 66.26% lower than the cost of subsidized electricity and diesel, respectively.

Published: July 2022

Drivers are vulnerable to inclement weather such as heavy rainstorms and severe rain-induced waterlogging. A thorough investigation of drivers’ driving behavior during rainstorms and waterlogging is a strong basis on which characteristics of traffic flow in such circumstances could be thoroughly studied; however, relevant studies from the individual perspective are very rare. In this paper, an experiment based on a driving simulator investigates the synergistic influence of rainstorm and waterlogging on drivers’ driving behavior, where a total of 47 drivers are recruited, and 30 circumstances with diverse rainfall intensities or water depth are included. The dataset of drivers’ driving behavior obtained from the experiment is furtherly analyzed using two-way analysis of variance (two-way ANOVA) and statistical analysis. The results show that rainfall, waterlogging, and their synergistic influence significantly reduce vehicles’ speed, acceleration, and deceleration, and increase headway distance generally. This indicates that the drivers tend to adopt a more conservative driving strategy when encountering stronger rainfall and more severe waterlogging. Moreover, waterlogging was found to have a much more significant impact on vehicles’ motion parameters than rainfall, and should be viewed with more importance. This study quantitatively analyzes drivers’ driving behavior from the individual perspective in circumstances of rainstorm and waterlogging, and the findings in turn strengthen our understanding of the impacts on driving behavior.

Published: July 2022

The concept of sustainability reporting is now an essential tool through which organisations demonstrate accountability to their stakeholders. The increasing market pressure coupled with the awareness of the consequences of organisations’ activities suggests the need for organisations to report their sustainability credentials. Sustainability performance reports should provide adequate information on organisations’ social, economic, and environmental performance. However, the current process through which organisations communicate their sustainability performance to stakeholders is questionable and remains a significant concern. This study assessed the current state and direction of research on sustainability performance reporting by conducting a bibliometric literature review of peer-reviewed studies on sustainability performance reporting published between 1987 and 2022. The findings highlight the misconceptions between sustainability and CSR when reporting organisations’ sustainability performance. Furthermore, businesses and scholars prioritise reporting instead of communication with stakeholders. The observed lack of engagement with stakeholders indicates that the reported performance may not reflect the impact of business activities on the three dimensions of sustainability. Rather than adopting a one-way information dissemination approach, this study concludes that the desired performance can only be achieved through two-way communication with stakeholders.

Published: July 2022

Suffering during events such as the COVID-19 pandemic threatens the quality of life (QoL) of older adults with physical and mobility disabilities. This study aims to determine the QoL of older Thai adults with such disabilities during the COVID-19 pandemic and its predictor. A cross-sectional study was conducted among 360 older adults with physical and mobility disabilities. Data were collected by structured interview questionnaires. Data analyses comprised Pearson’s correlation coefficient and multiple regression analysis. The mean age of the participants was 73.52 years; a total of 58.6% of them were female and 97.8% had completed only primary education. More than half of them had a moderate QoL (63.3%). Self-esteem, age, and perception of the benefits of disability were found to be associated with the participants’ QoL (p < 0.05) and capable of predicting it with 54.7% accuracy. As self-esteem and the perception of the benefits of disability were found to be indicators of the QoL of older adults with physical and mobility disabilities, the healthcare providers of such older adults should organize activities that could enhance their self-esteem and the perception of the benefits of disability to improve their QoL, particularly during the COVID-19 pandemic.
Risk and Uncertainty at the Outbreak of the COVID-19 Pandemic
Authors: Nisani Doron , Qadan Mahmoud , Shelef Amit
Published: July 2022

The classic paradigm in finance maintains that asset returns are paid as a compensation for bearing risk. This study extends the literature and explores whether asset prices are also affected by uncertainty. This research invokes the Expected Utility with Uncertainty Probabilities Model and utilizes the natural experiment conditions of the COVID-19 pandemic outbreak, in order to determine whether investors’ behavior during the sharp economic decline was driven by risk, or uncertainty. We limit this research only to the outbreak of the pandemic, since the recovery of the markets suggests investors have adjusted to the unexpected nature of the crisis. Using high-frequency data of the S&P 500 Index, we estimate the investors’ risk and ambiguity aversions, finding that in the pre-pandemic period investors exhibited risk aversion as well as an ambiguity-seeking attitude, while during the pandemic they demonstrated risk- and ambiguity-neutral behavior. The implications of these findings could suggest that in regular times, the financial markets are operated by risk-averse investors with decreasing risk-averse behavior.

Authors: Zarębski Patrycjusz , Czerwińska-Jaśkiewicz Małgorzata , Klonowska-Matynia Maria
Published: July 2022

Entrepreneurs in peripheral areas need to fully utilize a multidimensional regional environment in order to reduce regional innovation gaps. To gain a deeper theoretical and empirical understanding of the determinants of innovation processes in peripheral areas, this article sheds light not only on hard infrastructure and financial factors, but also on institutional, social, and relational factors. Studies of innovation in peripheral areas were conducted with the classic concept of regional innovation systems. Based on the results of a survey among 300 entrepreneurs in Polish peripheral regions, it was found that peripheral regions suffer from a deficit of human and social capital, particularly local leaders and mentoring and networking assistance. In addition, the analysis shows that peripheral regions do not have an effective innovation development strategy, lack institutional capital, and local authorities are not working to remove local barriers.
Collaborative Consumption: A Study of Sustainability Presentation in Fashion Rental Platforms
Authors: McCoy Lindsay , Chi Ting
Published: July 2022

Despite the increased research into the business potential and environmental impact of fashion renting, no previous research has studied the sustainable presentation of fashion (apparel, textiles, shoe, accessory, or jewelry) rental company platforms, which is the purpose of this study. The triple bottom line framework and content analysis methods were used to identify themes in their communications. An open coding method was applied to develop first-level concepts and sub-categories, followed by a calculation of the frequency of the aspects addressed on each website. A total of 56 active fashion rental businesses in the U.S. were identified and analyzed. A total of 11 main themes and 27 sub-themes emerged. The companies with the overall most mentioned sub-themes were REI and The Lauren Look by Ralph Lauren. The results indicate that sustainability information on company websites needs to be more organized for clear presentation and easy access to the public. Many companies can make simple adjustments such as educating consumers on the sustainable nature of their business model and providing data-related evidence for determining the social and environmental impacts. Companies must also provide more detailed information on COVID-19 cleaning/sanitizing practices to reduce the perceived risk while promoting consumers’ willingness to try fashion rental services.

Published: July 2022

The impact of natural disasters on rural areas has recently increased, the question of how to effectively improve the livelihood resilience of rural residents has therefore become an essential issue. In this context, a livelihood resilience evaluation index system for rural residents was constructed in four dimensions: livelihood quality, livelihood promotion, livelihood provision, and disaster stress. A structural dynamics model was used to analyze the changing characteristics of the livelihood resilience of rural residents in China between the years 1980 and 2020, and a livelihood resilience trend from 2021 to 2030 was predicted based on the ARIMA model. The main factors influencing livelihood resilience were explored using ridge regression analysis. The results show that: (1) livelihood resilience of rural residents in China fluctuated significantly between 1980 and 2020, tending generally to increase; (2) livelihood resilience is positively correlated with livelihood quality, livelihood promotion, and livelihood provision, while it is negatively correlated with disaster stress; (3) livelihood quality, livelihood promotion, and livelihood supply will still increase between the years 2021 and 2030, while the increase of livelihood resilience will tend to slow down; and (4) six variables have a significant positive impact on livelihood resilience, and provide a basis for the subsequent enhancement of livelihood resilience.
Sustainability of Chinese Village Development in a New Perspective: Planning Principle of Rural Public Service Facilities Based on “Function-Space” Synergistic Mechanism
Authors: Qiu Zhi , Wang Yue , Bao Lei , Yun Binwei , Lu Ji
Published: July 2022

Public service facilities are important carriers of sustainable rural development. However, the “holistic” planning principle for cities has resulted in the inefficient use of public service facilities in villages. Under the guidance of the sustainable development of rural areas in China, relying on the theory of “destination attractiveness” in tourism studies, this research puts forward the assumption that the real logic of the operation of rural facilities lies in the synergistic attraction between function and space for villagers. This study applied research methods such as field survey, questionnaire survey, importance–performance analysis, space syntax, and Spearman correlation analysis. It builds the “demand-frequency” coupling model of the facilities and explains the functional attractive attributes and degrees of four types of facilities in the coupling between different demands and use frequencies. Through analyzing the accessibility and traffic potential of rural facilities and the correlation between facility numbers and their spatial distribution characteristic parameters, the study reveals the synergistic mechanism between the functional and spatial attraction of the “selected facilities”. It is to clarify the planning principle of rural public service facilities based on villagers’ demands, to put forward the basic guarantee framework for different combinations of “functional attributes and spatial distribution” under the goal of good facility operation, and to achieve the goal of improving the resource efficiency and upgrading the level of the rural living environment. Eventually, it contributes to the sustainable development of rural China with theoretical and methodological support.

Published: July 2022

In recent years, some general cryptographic technologies have been widely used in network platforms related to the national economy and people’s livelihood, effectively curbing network security risks and maintaining the orderly operation and normal order of society. However, due to the fast development and considerable benefits of quantum computing, the classical cryptosystem faces serious security threats, so it is crucial to analyze and assess the anti-quantum computing ability of cryptographic algorithms under the quantum security model, to enhance or perfect the design defects of related algorithms. However, the current design and research of anti-quantum cryptography primarily focus on the cryptographic structure or working mode under the quantum security model, and there is a lack of quantum security analysis on instantiated cryptographic algorithms. This paper investigates the security of AES-OTR, one of the third-round algorithms in the CAESAR competition, under the Q2 model. The periodic functions of the associated data were constructed by forging the associated data according to the parallel and serial structure characteristics of the AES-OTR algorithm in processing the associated data, and the periodic functions of the associated data were constructed multiple times based on the Simon quantum algorithm. By using the collision pair, two collision forgery attacks on the AES-OTR algorithm can be successfully implemented, and the period s is obtained by solving with a probability close to 1. The attacks in this paper caused a significant threat to the security of the AES-OTR algorithm.

Published: July 2022

In recent years, the foment for sustainable and reliable micro energy grid (MEG) systems has increased significantly, aiming mainly to reduce the dependency on fossil fuels, provide low-cost clean energy, lighten the burden, and increase the stability and reliability of the regional electrical grid by having interconnected and centralized clean energy sources, and ensure energy resilience for the population. A resilient energy system typically consists of a system able to control the energy flow effectively by backing up the intermittent output of renewable sources, reducing the effects of the peak demand on the grid side, considering the impact on dispatch and reliability, and providing resilient features to ensure minimum operation interruptions. This paper aims to demonstrate a real-time simulation of a microgrid capable of predicting and ensuring energy lines run correctly to prevent or shorten outages on the grid when it is subject to different disturbances by using energy management with a fail-safe operation and redundant control. In addition, it presents optimized energy solutions to enhance the situational awareness of energy grid operators based on a graphical and interactive user interface. To expand the MEG’s capability, the setup integrates real implemented hardware components with the emulated components based on real-time simulation using OPAL-RT OP4510. Most hardware components are implemented in the lab to be modular, expandable, and flexible for various test scenarios, including fault imitation. They include but are not limited to the power converter, inverter, battery charger controller, relay drivers, programmable AC and DC loads, PLC, and microcontroller-based controller. In addition, the real-time simulation offers a great variety of power sources and energy storage such as wind turbine emulators and flywheels in addition to the physical sources such as solar panels, supercapacitors, and battery packs.
Robust Multi-Objective Design Optimization of Water Distribution System under Uncertainty
Authors: Boindala Sriman Pankaj , Ostfeld Avi
Published: July 2022

The multi-objective design optimization of water distribution systems (WDS) is to find the Pareto front of optimal designs of WDS for two or more conflicting design objectives. The most popular conflicting objectives considered for the design of WDS are minimization of cost and maximization of resilience index which are considered for the current study. Robust multi-objective optimization is to find the optimal set of the Pareto front considering demand is uncertain. The robustness is controlled by a single parameter that defines the size of the uncertainty set it can vary. The study explores ellipsoidal uncertainty set with different sizes and co-variance matrices. A combined simulation–optimization framework with a combination of self-adaptive multi-objective cuckoo search (SAMOCSA) and the fmincon optimization algorithm is proposed to solve the robust multi-objective design problem. The proposed algorithm is applied to medium and large WDS. The main contribution of this paper is to study the effect of demand uncertainty and the correlation on the WDS designs in a multi-objective framework. The study shows that the inclusion of correlation into the multi-objective design framework can significantly affect the optimal designs.

Published: July 2022

In this study, spatiotemporal fluctuations in surface water quality in Vinh Long province, Vietnam, were conducted using entropy weighting, water quality index (WQI), and multivariate statistical techniques, such as cluster analysis (CA), principal component analysis (PCA), and discriminant analysis (DA). The samples collected at 63 monitoring locations in March, June, and September were measured for 15 parameters. Compared to the Vietnamese standard, surface water was contaminated with organic matters, nutrients, microorganisms, and salinity. DA identified the most typical parameters (pH, turbidity, TSS, EC, DO, Cl−, E. coli, coliform) in distinguishing temporal variations in water quality with greater than 75% of the correction. CA group 63 sampling sites into 22 clusters representing different land use patterns. WQI determined the worst water quality was found in the agricultural areas. Based on the results of entropy weighting, EC, coliform, N-NH4+, BOD, N-NO3−, and Fe had significantly controlled surface water quality. Four principal components obtained from PCA explained 66.45% of the variance, suggesting the influences of geohydrological factors and anthropogenic activities, such as domestic, market area, agriculture, and industry. The findings of this study can provide useful information for authorities to evaluate the effectiveness of monitoring systems and plan for water quality management strategies.
Temporal and Geographic Stress Testing of Entrepreneurial Proportionalities in United States Counties
Authors: Toerien Danie Francois
Published: July 2022

Urbanization is one of man’s greatest challenges. Its handling requires a better understanding of orderliness in the demographic–socioeconomic–entrepreneurial domain of human settlements. Operating business enterprises are manifestations of successful entrepreneurship, which is the characteristic of interest here. Non-linear entrepreneurial proportionalities can be detected through the use of log–log regressions (power law analyses). Such analyses revealed many entrepreneurial proportionalities in datasets of a large number of U.S. counties. This enabled the examination of the temporal and geographic sensitivities of three entrepreneurial types: total entrepreneurship (expressed in total enterprise numbers), new entrepreneurship (the ability to successfully start enterprises of types not yet present), and existing entrepreneurship (the ability to start more enterprises of types already present). Stress testing of the entrepreneurial proportionalities during a period of economic growth (2000 to 2007) followed by a period of economic decline (the so-called Great Recession from 2007 to 2010) enabled the examination of a hypothesis that suggested that the entrepreneurial proportionalities are not temporally or geographically sensitive. The hypothesis is accepted for new and existing entrepreneurship. Total entrepreneurship is geographically sensitive, but not temporally. There is apparently no lack of entrepreneurship in human settlements. Their total entrepreneurship (expressed as total enterprise numbers) appears to be a function of their population sizes and prosperity/poverty levels.

One of the most important food sources for humans is the soybean crop because it is an important source ofprotein and oil, which makes it important to improve its productivity under stress conditions, especially in sandy lands.Therefore, the study aimed to improve soybean productivity by using biological fertilizers in the presence of organicfertilizer and low concentration of mineral fertilizer under new sandy soil conditions.The experiment was carried out intwo summer seasons of 2020 and 2021 at the Ismailia Research Station, Ismailia Governorate. The used inoculates inthe experiment were,an identified Streptomyces strain,Bacillus megatherium, (SEWRI) and Bradyrhizobiumjaponicum(Okaden) as,biofertilizer agents.Activated dose of N-fertilizer was used in seven different treatments. Results showedthat Bradyrhizobia+Bacillus+actinomycetes+20 kg nitrogen fertilizer/fed was effective in the presence of organicfertilizer compared to organic fertilizer-free soil or un-inoculated+70 kg N/fed. Bradyrhizobia+ Bacillus+Actino+20 kgN/fed (T14) was the most effective treatment in the presence of organic fertilizer compared to organic fertilizer-free soilor uninoc.+70 kg N/fed. Promising expected yields of each of seeds and straw (Ton/fed) of soybean plants cultivatedunder different fertilizers and biofertilizers conditions expected was clear from increasing the yield seed up to1.8400Ton/fed in the presence of organic fertilizer (T14) compared to 1.4565 when soybean was cultivated in theabsence of organic fertilizer (T01). This could be supported by the amounts of NPK, N-percentage, and protein content,numbers of branches and pods and dehydrogenase activity in soil. Significant differences between the straw yield in thepresence and absences of organic fertilizer as well as biofertilizers were recorded. Organic fertilizer applicationrecorded the highest significant increases in nodulation status, growth and straw nitrogen content as well as harvestparameter of soybean compared with those un-received organic fertilizer

Published: July 2022

Many environmental and biological factors could be effective on estimation of genetic parameters in progeny trials. Number of blocks (also called as replicate) is one of the most important environmental factors in these estimations. Effect of block scenarios on genetic parameters were investigated based on height and diameter at breast height in a 23-year-old progeny trial established by 4 blocks of seed stand and seed orchard seedlings of Turkish red pine (Pinus brutia Ten.) in this study. Averages were 14.14 m for tree height and 17.69 cm for diameter at breast height in polled seed sources. Generally significant (p<0.05) differences among blocks, and families for the traits in the scenarios were found by results of analysis of variance. While variance of error was similar for both traits, there were large differences were estimated among other variance components for the scenarios. Individual heritability, phenotypic coefficient of variation, genetic coefficient of variation, and genetic gain varied for the traits and block scenarios. Results of the study emphasized effect of block numbers on genetic parameters

The technique can be used in forestry when creating and modeling protective forest stands around nursery’s objects. The equipment is designed for sites that are difficult to restore or inaccessible to ground-based mechanization and human means. Hard-to-recover sites are defined as: 1) released as a result of deforestation, including fire, ineffective for the operational technology of ground-based sowing or planting; 2) released as a result of fires, ineffective for the operational technology of ground seeding or planting; 3) inaccessible to ground-based mechanization facilities for climatic and geomorphological reasons; 4) inaccessible to people due to the complication of the radiation background and (or) after man-made disasters. The technique provides for accelerating the process of creating forests and improving environmental safety for the environment by reducing the number of operations that violate the forest ecosystem, using environmentally friendly energy sources in unmanned aerial vehicles, equipment and devices used in all groups of operations, improving environmental safety for humans by enabling the implementation of the method without the presence of an operator directly at the site of the groups of operations, reducing the cost of performing energy-intensive and time-consuming operations for preparing sites, transportation of forest reproductive material to the place of preliminary preparation and back
INVESTIGATION OF THE INFLUENCE OF AUGER DRUM PARAMETERS OF FOREST FIRE SOIL-THROWING MACHINE WITH THE FUNCTION OF FIRE-BREAK MAKER ON THE QUALITY OF SOIL FLOW CLEANING FROM THE GROUND COVER
Authors: Popikov Petr , Pozdnyakov Anton , Gnusov Maksim , Petkov Aleksandr
Published: July 2022

Currently, the most common way to prevent and extinguish forest ground fires is laying of mineralized strips and ditches using forest plows, milling strip-laying machines and soil throwers. However, fire-break making soil throwers are not equipped with devices for removing the ground cover with combustible plant residues from the soil flow supplied to the fire zone when extinguishing forest ground fires, which significantly reduces the efficiency of the machine. Augers with a hydraulic drive are promising, which allow removing the ground cover, however, additional studies of kinematic and dynamic parameters are needed. The purpose of this work is to improve the quality of cleaning the flow of soil from the ground cover supplied to the edge of the fire by a forest fire stripper by substantiating the parameters of the auger working bodies. The analysis of literary sources showed that it is advisable to use modern mathematical models of the interaction between an object and the environment, based on the particle dynamics method, in the development of a forest fire soil-throwing machine. A new design of a forest fire soil thrower with auger working bodies, which are designed to remove the ground cover, is presented. A simulation model of the working process of auger working bodies using the particle dynamics method was compiled. A basic computer experiment was carried out to clean the soil flow from the forest litter. It has been established that pressure in the hydraulic motor decreases approximately exponentially, and the rotational speed of the working body also increases approximately exponentially up to 4 rpm during the acceleration of the working body. The interaction of the working body with the stump led to the appearance of a negative braking torque of up to 4.5 kNm. As a result, the rotational speed of the drum decreased from 4 rpm to almost zero. With a decrease in the rotational speed, the pressure in the hydraulic motor of the drive of the working body increased to 12.5 MPa. The auger working body provides approximately the same cleaning efficiency of the soil flow with a ground cover thickness of up to 20 cm, while the cleaning completeness is at least 0.86, and the power consumption is not more than 8 kW

Authors: S Donisha
Published: July 2022

Novel literature is one of the literary genres that has a special place in Tamil literature. The novel was created to point out the quality of life of the people in society. Solai Sundara Perumal is one of the best creators in today's fictional world. In his novel Tappaattam, he documented the biographies of marginalized people who are oppressed in society. The people of Pariyar, Pallar, and Sakiliya are portrayed as enslaved by the ruling class due to their economic status and caste status. From time immemorial, the novel depicts the frustrations, struggles, and desires of the people who have sacrificed their lives as slave laborers for imperialism and are living their lives without fulfilling any desires. People who live under the laws of the ruling class are subjected to various hardships due to birth. Due to such caste differences, the life struggles of the marginalized people have caused them great stress.
Effect of Regional Dialects in Learning Tamil Language
Authors: N Sulochana
Published: July 2022

Having two forms of practice, the spoken and written, is a peculiarity that the Tamil language has. In written form the language is used with no grammatical errors. Spoken form is the one that people use in their daily language as they speak. This colloquial usage is most importantly used to express human emotions. It can be observed that, spoken form of language and the pronunciation of words differ according to region, race and caste. The word is subject to change depending upon these factors while the meaning remains constant. When a word differs from the common usage based on the region, race or caste it is called as a regional dialect. Tamil language is considered to be the oldest language, the one that man spoke first. It has a rich sense of nativity and intellectual depth. Language is not just a medium, it is also an identity for the race that used it. It becomes our responsibility to document it. Regional dialects are assets to a language. While teaching such language, along with teaching the meaning of lessons, vocabulary and its usage should also be taught in order to have a deeper understanding about the taught meaning. Only then Tamil’s richness could be internalised.  A teacher should elaborate the influence that regional dialects have on a language, in order to make the process of language learning fruitful. A child’s primary learning begins at home before it steps into a school. This research article reflects the impacts that understanding the changes in people and their language while exposed to the external environment from home environment has on the process of learning.

Introduction: Current school teaching methods including distance learning may have adverse health effects in children.
Objective: To assess health effects of online education in students of comprehensive secondary schools and gymnasiums.
Materials and methods: We developed a questionnaire to establish the impact of distance learning on the functional state and health of students comprising three sections: educational activities, daily routine and self-rated health. In May 2020, 3,026
fifth to ninth-year students from eight comprehensive schools and five gymnasiums of the city of Nizhny Novgorod, including 1,430 boys and 1,596 girls, filled out the questionnaire and their answers were then analyzed using IBM SPSS Statistics
software, version 5.1.
Results: Distance learning included online and offline classes (70.7 % in total) and self-study assignments, the latter being more common in the comprehensive schools than in the gymnasiums. The majority of the respondents from the schools (73.4 %) and gymnasiums (67.0 %) noted a greater amount of homework during e-learning compared to offline education. They also reported less time spent outdoors and much more passive leisure. Complaints of increased back and wrist pain and headaches were more frequent in the students of comprehensive secondary schools.
Conclusions: Our findings show that distance learning changed the way of life of all the children surveyed. We observed an increased screen time, the prevalence of static activities, and the development of musculoskeletal and eye disorders. The comprehensive school students noted more negative consequences of online learning compared to their peers studying in the gymnasiums.

Penelitian kecernaan mengunakan metode in vitro dengan pakan yang mengandung level asam laurat dan serat kasar berbeda untuk mengukur tingkat kecernaan bahan kering dan bahan organik pakan. Penelitian ini menggunakan rancangan acak lengkap (RAL) pola faktorial 3x2x4. Faktor A adalah level asam laurat yaitu A1 = 1,3%; A2 = 1,95%; dan A3 = 2,6%. Faktor B adalah level serat kasar yaitu B1 = 6% dan B2 = 8%. Setiap kombinasi perlakuan diulang 4 kali. Parameter yang diukur adalah kecernaan bahan kering dan kecernaan bahan organik tahap 2 (pepsin digestibility), serta kadar air dan kadar abu pakan. Hasil analisis keragaman menunjukkan bahwa perlakuan memberikan pengaruh berbeda sangat nyata (P<0,01) terhadap kecernaan bahan kering (36,48% - 41,87%) dan kecernaan bahan organik (33,21% - 38,69%) serta kadar air (11,98% - 13,66%) dan kadar abu pakan (8,09% - 11,30%). Peningkatan pemberian level asam laurat memberikan tingkat kecernaan yang lebih baik ini disebabkan karena mempunyai bobot molekul yang lebih kecil sehingga tidak diperlukan energi yang tinggi dan hanya membutuhkan sedikit enzim untuk memecah lemak tersebut menjadi bentuk yang siap diserap. Berdasarkan hasil penelitan yang telah dilakukan dapat ditarik kesimpulan penggunaan 2,6% level asam laurat dan 6% serat kasar memberikan kecernaan bahan kering dan bahan organik secara in vitro yang lebih baik. Kata Kunci: Asam laurat, serat kasar, kecernaan
