A Framework to Study Farmers Decisions on Adoption of Agromet Advisories Services for Risk Management: Insights from Theory of Planned Behavior
Authors: Rohit Jagriti , Beevi C.N. Anshida
Published: March 2022

Background: Climate change is emerging as a major threat on agriculture, food security and livelihood of millions of people in many places of the world. Agromet advisories services is such a climate resilient technology which provides the valuable information about all agricultural operations from land preparation sowing to harvest based on weather forecasting. There have been plenty of studies investigating farmers’ decision to adopt an innovation but a lot of more segregated studies exist, highlighting the importance of individual factors affecting adoption. Most of the theoretical models on adoption of innovation have tended to present discipline guided explanations to the adoption decision, although adoption is subject to a combination of social, economic, psychological, as well as cultural factors.
Methods: The aim of the paper is to present a framework to study farmer’s decision with respect to adoption of AAS. Under aegis of NICRA, Agromet Advisories are provided to the farmers through its 121 Krishi Vigyan Kendra located in India. The agromet advsiories along with weather data gives crop specific recommendations. Generally, these advisories ae given to farmers two times in a week. The developed framework will be used to study their intention to adopt these AAS. Extensive review of literature on the adoption of innovation in agriculture that was based on TPB or theory of reasoned change (TRA) was carried out.
Result: Various factors were taken into consideration like the demographic variables, socio- psychological constructs for explaining the adoption decisions. The framework developed for the study is an extended version of ajzen’s Theory of Planned Behavior (TPB). In addition to the traditional construct i.e intention, perceived behavioural control and subjective norms, perceived usefulness was added to the extended version of TPB to study the adoption of Agromet Advisories Services (AAS). The framework will help the academician, policy makers and other stakeholder to develop different perspectives of farmer’s decision making in adoption of AAS.

Published: March 2022

Background: PPARGC1A gene mediates expression of genes involved in gluconeogenesis and is regarded as a prominent candidate gene governing the effect of milk fat in dairy bovines. The study was planned to identify DNA polymorphisms in the PPARGC1A gene in Gaolao Cattle and to find their association with milk production traits in Gaolao cattle. Methods: The blood was collected from 224 purebred Gaolao cattle from farm and field along with test day milk from each cow for estimating milk components. Genomic DNA was assessed using phenol-chloroform extraction method and Kits. PCR-RFLP, PCR-SSCP and direct DNA sequencing methods were used to identify polymorphism. Result: PPARGC1AG1- NheI locus of 3ʹUTR region were polymorphic with allele frequency for A alleles as 0.84 and for allele B as 0.16. In studied animals, significant differences were not observed for milk traits between genotypes at PPARGC1A-NheI locus. The analysis at PPARGC1AG4-SSCP revealed no significant differences in milk traits; however sequencing revealed SNP. PPARGC1AG1- NheI genotype-based sequencing revealed T greater than C SNP at 263rd position 02 computational SNPs viz; C-T at 263rd position and A-T at 268th position. The identified variation at the PPARGC1A gene may aid in identifying associations for development of markers for selection and genetic improvement.
Study on Applicability of Genotype × Yield × Trait (GYT) Biplots over Genotype × Trait (GT) Biplots in Selection of Maize Hybrids across Soil Moisture Regimes
Authors: Singamsetti Ashok , Shahi J.P. , Zaidi P.H. , Seetharam K.
Published: March 2022

Background: A large area of the maize production in Indo-Gangetic plains of India exposes alternative and combination of prolonged drought spells and heavy rainfall situation due to uncertainty of monsoon patterns. In such context, breeding for maize hybrids with cross-tolerant to both low and excess soil moisture stresses remain the ultimate alternative. Methods: Evaluation of 75 maize hybrids planted at Banaras Hindu University, India during the subsequent Rabi and Kharif seasons of 2017 and 2018, respectively. The hybrids were evaluated for acquiring information on inter-trait associations among yield and yield-related traits under different soil moisture regimes. The trials were planted in alpha-lattice design and managed stress was imposed and data recorded. Result: As our investigation was the evident of weak correlations among the traits studied, genotype × trait (GT) biplots are not advisable to select/ discard the genotypes under moisture stress conditions. The goodness of fit for GT biplots constructed under studied moisture conditions were almost poor because of fair to moderate correlations among the traits. To accomplish this problem of weak associations, genotype × yield × trait (GYT) technique was advisable to perform the precise selection of genotypes under studied environments. The investigation emphasized on accuracy and adequacy in implementing of GYT biplots for characterizing and selecting suitable hybrids.
Parental involvement in Kosovar education: Relationships with gender, education and employment variables
Authors: Turtulla Sermin , Lopar Elsev Brina
Published: March 2022

This article aims to make an initial probe into parent involvement in children’s academic-related activities and how this is affected by the parents’ gender, education and employment variables. Most of the articles written on parental academic support focus on corroborating the positive relationship of parental involvement with student school achievement and cover samples from countries other than Kosova. This is the first correlational study which aims to show the significance of relationships of the specific demographic variables of Kosovar parents and the frequency of their homework help. Data are analysed using frequency distribution and chi-square for the correlation significance. The findings corroborate a higher percentage of females in parental involvement, and a negative correlation of parental involvement with employment and level of education. Implications and explanations for future research and practice are discussed.

Keywords: Academic success, homework help, Kosovar education, parent involvement, primary level.

Delayed versus on arrival modified live viral vaccination in stocker cattle on bovine respiratory disease
Authors: Ambs Ashlee , Capik Sarah , Moberly Heather
Published: March 2022

PICO question

In auction market calves at high risk of developing bovine respiratory disease (BRD), does delayed (14–30 days) vaccination with a modified live vaccine (MLV) for viral respiratory pathogens versus administration of MLV on arrival (within 24 hours of arrival) to the stocker operation, result in less calves with BRD morbidity diagnosed based on visual signs and rectal temperature >40°C, or less calves with BRD mortality?

 

Clinical bottom line

Category of research question

Treatment

The number and type of study designs reviewed

Four papers were critically reviewed. All were randomised complete block designs

Strength of evidence

Moderate

Outcomes reported

In stocker calves, delaying administration of a MLV for respiratory viruses may result in numerically lower initial BRD morbidity rates, while giving at arrival may result in numerically lower BRD retreatments. One study shows statistically lower cases of BRD morbidity after the third antimicrobial treatment in cattle vaccinated on arrival with both a clostridial and MLV for respiratory viruses compared to cattle vaccinated on arrival with clostridial vaccine and delayed MLV for respiratory viruses. No conclusion about mortality can be drawn due to inconsistent numerical conclusions between studies

Conclusion

Due to conflicting evidence and a general lack of statistically significant differences in morbidity and mortality outcomes, a definite answer regarding the impact of delayed MLV respiratory vaccination in stocker calves cannot be made

 

How to apply this evidence in practice

The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.

Authors: Mudin Moh Isom , Fikri Muhammad Dhiaul , Shobirin Munar Moh , Mukharom Rohmah Akhirul
Published: March 2022

Penelitian ini bertujuan untuk mengkaji tentang munculnya upaya penerapan hermeneutika sebagai pendekatan penafsiran al-Qur’an yaitu yang dikembangkan oleh Hans-Georg Gadamer dengan istilah Wirkungsgeschichte. Teori ini berhasil memikat Amina Wadud Muhsin untuk mengadopsi demi mencapai kepentingan dan tujuan tertentunya. Metode penelitian yang digunakan adalah kepustakaan. Penelitian ini menyimpulkan bahwa hermeneutika Hans-Georg Gadamer jelas bermasalah dan tidak mungkin diaplikasikan dalam penafsiran Islam karena ia bersumber dari tradisi ahli kitab dalam memahami kitab suci mereka. Jika hermeneutika dipaksakan untuk menafsirkan ayat-ayat al-Qur’an, maka sama saja ingin menjadikannya sebagai alat untuk mengkritisi ayat-ayat dalam al-Qur’an.

Criticizing apartment ownership regulation in Indonesia
Authors: Raharningtyas Marditia Putri Purbasari , Hasiholan Andrew David , Wijaya Valencia
Published: March 2022

Housing is a basic necessity, yet land availability is limited. This phenomenon urges residents to resort to vertical living and developers to provide vertical housing. The escalation of the vertical housing market has raised potential issues, particularly the use of strata titles in commercial properties advertisement. Strata title is proof of apartment unit ownership which has been widely recognized in the common law system. Meanwhile, Indonesia as a country that adheres to the civil law system regulates apartment ownership based on SHMSRS or Certificate of Apartment Ownership. This practice will result in legal consequences in the ownership status. Hence, this research is carried out by comparing the concept of strata title in the civil law and common law legal systems through a normative juridical methodology based on a statutory and conceptual approach. This study strives to differ strata title and SHMSRS concept to provide a comprehensive knowledge of apartment ownership and prevent legal problems from surfacing in the future.
Special Issue on Self-Optimizing Machining Systems
Authors: Kakinuma Yasuhiro , Kono Daisuke
Published: March 2022

The concept of Self-Optimizing Machining Systems (SOMS) has been proposed against the background of Industry 4.0 and the Digital Twin concept, based on cyber-physical systems. In order to improve manufacturing productivity, quality, and efficiency, each component technology related to the machining process, such as CAD/CAM, process modeling/simulation, process monitoring/control, and workpiece assessment, as well as the machine tools themselves, has been developed independently to date. However, series of processes, including the interactions among these component technologies, have finally determined the machining performance and the quality of the products. SOMS deals with the information links among these components comprehensively and plays the important role of combining these links and functionalities to optimize the overall machining system. Nevertheless, an intensive implementation and combination of these technologies has yet to become state-of-the-art in industry, while further research and development for SOMS is required for Industry 4.0 and Digital Twin.

This special issue focuses on the research trends of SOMS, especially the interaction links among machine tools, process monitoring, and work assessment. From researchers who are active on the front lines of manufacturing engineering, the latest achievements related to the development of SOMS are presented in 6 papers. On one hand, the development of sensor-integrated components is indispensable for SOMS to monitor the status of a process and feed it back to a related component in order to control the machining process and its environment. On the other hand, it can be said that visual simulation, virtual metrology, and other epoch-making, on-machine technologies for evaluating machined surfaces, as well as process optimization based on machined surface information, are strongly required.

We hope this special issue will contribute to future research and development for researchers and engineers in the field of manufacturing and machining systems.

Authors: Rodríguez Rodríguez Ignacio , Sanhueza Martínez Paulina
Published: March 2022

El trabajo busca explorar las condiciones de diversificación o concentración productiva de las regiones en Chile, identificando sus especializaciones sectoriales relativas. Para lo anterior, para cada región se calculan indicadores de diversificación/concentración productiva -Índice de Herfindahl (IH)- e indicadores de especialización sectorial -Coeficiente de Especialización (CE)- utilizando fuentes de información secundaria. Los resultados indican que, en general, las regiones de Chile se muestran como territorios diversificados. En efecto, algunas regiones se especializan en actividades económicas para las cuales disfrutan de ventajas comparativas, como es el caso de las regiones mineras del norte, mientras que otras se benefician de la diversificación de su base productiva, como ocurre en la Región Metropolitana. No obstante, en algunas regiones, y a nivel nacional, existe una excesiva dependencia de los recursos naturales, lo cual puede comprometer el potencial de desarrollo de las regiones, y del país en su conjunto.

Authors: Fedorovich Vladimir , Pyzhov Ivan , Ostroverkh Yevgeniy , Pupan Larisa , Garashchenko Yaroslav
Published: March 2022

An expert system of the grinding process has been developed, which makes it possible to predict and optimize the process of defect-free processing of both existing and newly created superhard materials. The expert system consists of two interconnected modules - theoretical and experimental. The theoretical module of the expert system allows, at a given level of significance, to determine the values of the output indicators and the kinetics of their change in the process of adaptability, depending on the physical and mechanical properties of the interacting materials and processing conditions. The experimental module of the expert system allows you to coordinate and correct the results of theoretical calculations when determining the optimal grinding and operating conditions for processing various grades of superhard materials. When optimizing the sharpening process of a blade tool, processing efficiency, consumption of diamond wheels, cost price and various quality indicators of its cutting elements can be selected as a criterion. The use of the expert system significantly reduces the amount of expensive and laborious researches in determining the optimal processing conditions for various grades of superhard materials (SHM), including newly created ones.

Published: March 2022

Due to the use of surface engineering methods, a combined technology for processing the working surface of internal combustion engines cylinder liners has been developed. The advantages and disadvantages of traditional liners processing technologies are analyzed, which allowed identifying ways to improve them. A new technological process of cylinder liners processing is proposed, which includes operations of deforming broaching and finishing antifriction non-abrasive treatment. The technological equipment and tools for the chosen technological process realization are chosen. Experimental studies of the proposed technical solutions feasibility are carried out. The microrelief of the treated surface, roughness parameters, hardness distribution according to the wall thickness were determined for the studied liners, and the amount of wear was determined for the liners after running-in. Parameters analysis of geometric, mechanical and tribological characteristics of the liners working surface, processed by the existing and proposed technology showed significant advantages of the latter. There is an increase in the productivity of processing part up to 4 times, reducing the cost of the tool up to 3 times, and in general – reducing the cost of restoring the liner. It is proved that the use of the proposed technology allows improving the physical-mechanical characteristics of the working surface: strengthening the surface layer to a depth of 0.3 mm, as well as obtaining a roughness close to the operational.

Authors: Mitsyk Andrii , Fedorovich Vladimir , Grabchenko Anatoliy
Published: March 2022

The factors that determine the efficiency and quality of vibration treatment are indicated. Characteristic cases of interaction of abrasive granules with the processed surface are noted. The influence of the hardness of the processed part material and the shape of its surface, as well as the influence of chemically active solutions on the efficiency and quality of vibration processing, is substantiated. The characteristics of abrasive granules and their volume ratio with the processed parts are given. It is indicated that the underestimation of the possibilities of vibration processing technologies is explained by their insufficient studies. It has been established that vibration processing, depending on the characteristics and composition of the processing medium, is a mechanical or mechanochemical removal of the smallest particles of metal or its oxides and plastic deformation of microroughness due to mutual collisions of the medium granules with the processed surface, caused by vibrations of the reservoir in which the processing medium and, the processed parts are placed. It is noted that, according to the classification, vibration treatment refers to mechanical processing methods and, in particular, to the group of mechanical-chemical processing methods or to combined methods when chemically active solutions are introduced into the working medium, It is also noted that vibration treatment refers to dynamic, and for technological purposes – to dimensionless processing methods, according to the type of tool used - to the group of processing methods with a free abrasive. It has been established that the efficiency of vibration processing depends on the oscillation modes of the vibrating machine, the mass of the processed parts and abrasive granules, the hardness of the parts material and the shape of their treated surfaces, the characteristics of the abrasive medium, the volume ratio of the parts and abrasive granules, as well as on the composition of the chemically active solution. The characteristic cases of interaction of abrasive granules with the processed surface are given. The situations of the highest processing productivity for performing the operations of vibration grinding, vibration polishing, washing and descaling have been established. It is noted how the hardness of the processed part and the shape of their surface affects the performance and quality of vibration processing operations. The characteristics of the working medium, which affects the efficiency and quality of vibration treatment, are given, including the influence of grain size and hardness of the material of abrasive granules. The volume ratios of abrasive and processed parts are considered. The types of actions on the vibration treatment processes are given.

Published: March 2022

Objectives. Owing to the functional and structural complexity of the head and neck area, the reconstruction of defects in these areas is challenging. Free flap surgery has become standard for the reconstruction of the head and neck with improvements in microvascular surgery. The aim of this study was to use the cumulative sum (CUSUM) method to evaluate the learning curve for free-flap head and neck reconstruction performed by a single surgeon.Methods. We retrospectively reviewed the medical records of 47 patients who underwent free-flap reconstruction from 2017 to 2021. The clinical demographics and surgical outcomes were analyzed. The total operation time was analyzed using the CUSUM method, which is an analytical approach for visualizing patterns in data by converting raw data into an accumulation of deviations from the average value.Results. CUSUM analysis showed two phases of the learning curve: phase 1 (cases 1–22) and phase 2 (cases 23–47). The operative time in phase 1 (579.9±128.2 minutes) was significantly longer than that in phase 2 (418.6±80.9 minutes) (P<0.001). The re-exploration rate was higher in phase 1 (31.8%) than in phase 1 (4%) (P=0.018). The flap failure rate was higher in phase 1 (9.1%) than in phase 1 (4%), but this difference was not statistically significant (P=0.593).Conclusion. The learning curve of free-flap head and neck reconstruction seems to stabilize after approximately 20 cases.

Concentration ability is the ability possessed by every child to focus and focus on doing or doing something. Based on research at the Roudhotul Anwar Sukodono Islamic Kindergarten, especially in the 4-5 year age group, 80% of children lack the ability to concentrate. Researchers have a good target of successful concentration power is 76%-100%, for that researchers use Rainbow Card media to improve children's concentration skills. has never been carried out before to improve the process of teaching and learning activities so that student learning outcomes increase. The class action uses 2 stages, namely pre-cycle and cycle I. In the pre-cycle activity, storytelling is applied and the results have not yet reached the target of success, with a total of 40.4%. In the first cycle activities implemented Rainbow Card activities and achieved the success target with a total of 80%. This shows that from the increase in the percentage of the average pre-cycle and cycle I, there has been a very good increase, so that this study can be judged to have met the specified success target, the results of the study in group A in Islamic Kindergarten Roudhotul Anwar were declared successful, this proves that the media Rainbow Card can improve the concentration ability of children aged 4-5 years at Islamic Kindergarten Roudhotul Anwar Sokodono.

Empty nest syndrome is a description of feelings of emptiness or emptiness that can be indicated by empty feelings such as loss, sadness, depression that elderly people feel when their children leave the house where they grew up. The factor that is thought to contribute to the height or the size of the empty nest syndrome is religiosity. Religiosity is a state within the individual where the situation can influence the daily actions and behavior of Muslims to conform to Islamic teachings and practices. The purpose of this study was to determine the relationship between religiosity and empty nest syndrome in the elderly in Larangan Village, Sidoarjo. The subjects in this study amounted to 157 people with Non-Probability sampling technique with quota sampling method. Subject criteria are elderly who are over 60 years old, are in the prohibition market area, Sidoarjo, and have empty nest symptoms such as loneliness, emptiness in married life. Methods of data collection using the scale of religiosity and empty nest syndrome scale. Data analysis used product moment correlation data analysis with the results obtained (r = -0.631; = 0.000). This shows that there is a negative relationship between religiosity and empty nest syndrome, which means that the higher the religiosity, the lower the empty nest syndrome, and the lower the religiosity, the higher the empty nest syndrome.

Published: March 2022

This study begins with anxiety about the learning process in schools that uses conventional and teacher-centered models, which affect the achievement of student learning outcomes. With the presence of the 2013 curriculum, it is clear that the learning process must be more active with a scientific and learner-centered approach. This is what then made the authors conduct research at SMA Islamiyah Babakan Karangpucung Cilacap to determine the learning process of Islamic Education with a scientific approach. This study aims to analyze: 1) Management of the factual PAI learning model, 2) Management of the hypothetical model of Islamic Education learning model with a scientific approach, 3) Finding the management of Islamic Education learning model that is in accordance with the scientific approach. This research was designed in the form of Research and Development (R & D). Data collection methods used were observation, interviews, and documentation. Meanwhile, to analyze the data using analysis with a phenomenological approach that departs from certain facts or phenomena that occur in the field and then conclusions are drawn. The results showed that: 1) the learning process still uses conventional and teacher-centered learning models. 2) developing a learning model based on a scientific approach. 3) the learning model with a scientific approach is appropriate to be used as an appropriate Islamic Islamic education learning model.

The particle size plays an important role in the mechanical behavior of granular geomaterials. With respect to the crushable granular soils, the particle breakage under different pressures leads to the variation of the particle size distribution of soils. Therefore, it is essential to accurately model the particle fracture process to reproduce the key response of granular soils in the simulation. In this study, two simulated approaches, cluster method and replacement method, were performed to investigate the particle size effect for the crushable granular soils by three-dimensional (3D) discrete element method (DEM). DEM simulations were validated through the available results of diametric and oedometric compression tests with the help of the Weibull statistics. Based on the evaluation at particle and assemble-scale, it is found that both the cluster method and replacement method could simulate the particle strength and size dependence of sample failure with a good agreement with experimental results. The particle breakage phenomenon is also successfully modeled in DEM simulation and analyzed by the breakage index. Meanwhile, the computational efficiency was analyzed compared with two simulated methods. The findings in this study can provide a viable approach to investigate the particle breakage effect of the crushable geomaterials.
