Authors: ATAMANENKO I.
Published: August 2024

The study is devoted to the study of the problem of formation of combat readiness of cadets of military institutions of higher education in the process of special and physical training. During the study, it was found that special training of military personnel is a system of measures aimed at mastering special techniques, actions, samples of special equipment for the purpose of performing official duties. It is revealed that the mastery of motor action occurs in the following methodological sequence: the formation of knowledge about the essence of motor action, the development of motor action in general, the development of automated skills. Differentiation of motor action into three levels is conditional, since there are no clear and stable boundaries for separation, but such a classification is necessary for the formulation and implementation of educational tasks. The development of physical fitness of future military personnel is carried out by improving physical qualities, the formation of professional and applied skills in moving across rough terrain, overcoming obstacles, hand-to-hand combat, military-applied swimming, etc. The content of physical training with a general orientation includes a variety of exercises, such as middle and long distance running, athletic gymnastics, exercises for the development of static and dynamic endurance, swimming, exercises in heights and stops (on bars and crossbeams) plyometrics, etc. Special physical training of cadets is a set of classes aimed at the development of physical qualities necessary for the performance of service and combat missions and focused on ensuring readiness and ability to act in various, including extreme conditions. The symbiosis of special and physical training programs for cadets provides an increase in the speed of shooting and the effectiveness of hitting the target, the development of skills for the rational use of fire weapons and tactical shooting techniques, increasing general and special endurance and strength, improving mental and physical health.

Published: August 2024

The article examines and theoretically analyzes modern technologies for the development of critical thinking of future physical culture and sports specialists in higher education institutions. Based on the analysis of a set of literary sources, it was established that the main characteristics of the critical thinking of future coaches are activity, reflexivity, logic, independence, and focus on solving real problems of physical culture and sports activities.
The concept of critical thinking is interpreted as a type of thinking that is characterized by activity, purposefulness, independence, discipline and reflexivity and involves the development in the learning process of a person's ability to identify problems, analyze, synthesize, evaluate information from any sources, put forward alternatives and evaluate them, to choose a way of solving a problem or one's own position in relation to it and justify one's views, make a conscious choice and act.
The main features (reflectivity, pragmatism, subjectivity) and stages (updating knowledge; awareness of knowledge, understanding (reflection) of the technology of critical thinking competence formation) are determined. In the work, the application of a set of conditions that determine the development of critical thinking of future physical culture and sports specialists is developed and argued.
The article outlines the specific features of teaching the disciplines of the professional-practical cycle of training a future physical culture and sports specialist on the basis of critical thinking. It has been proven that critical thinking includes a set of operations that determine the individual's ability to analyze, compare, synthesize and evaluate information from various sources; understand the problem and assess its depth; formulate hypotheses and consider alternative solutions; make deliberate and informed decisions.

Dandelion is a well-known edible and medicinal plant with numerous studies of its health benefits. Interest presents its polyphenolic and carbohydrate composition and its non-polar components in the aerial parts and roots have been identified. There are no studies about the composition of the fatty acid phytocomponents in the flowers of the dandelion. The main purpose of the present study is a comparative investigation of n-hexane, ethanol, and n-hexane/ethanol (1:1 v/v) soluble compounds from dandelion flowers (Taraxacum officinale Weber ex F.H. Wigg.) collected during the flowering period. The GC-MS analysis of the non-polar (lipid) fractions showed the presence of 30 biologically active phytocompounds. The fatty acids predominated in the investigated extracts [(50-60 % of total ion current (TIC)], followed by triterpenes (9-11 % of TIC) and phytosterols (7-8 % of TIC). Polyunsaturated fatty acids - linoleic acid and α-linolenic acid (10 – 15 % of TIC) were identified as the major components. Phytosterols were mainly represented by β-sitosterol (3-4 % of TIC) and stigmasterol (above 2% of TIC), while pentacyclic triterpenes from cycloartenol 3-acetate (3-4% of TIC) and β-amyrin (above 2% of TIC) were found. Based on the fatty acid profile, the nutritional indices directly correlated with the lipid metabolites profile responsible for human health were calculated: Index of atherogenicity (IA) – 1.2-1.6; Index of thrombogenicity (IT) – 0,6-0,7; Hypocholesterolemic/hypercholesterolemic (HH) ratio – 1.0-1.3; Health-promoting index (HPI) – 0.6-0.8; Unsaturation index (UI) – 72 and linoleic acid/α-linolenic acid (LA/ALA) ratio – 1.1. The current results reveal the nutritional potential and health benefits of edible dandelion flowers.

For centuries, thyme has been used as a spice and medicinal plant. Of the more than 350 established species of plants of Thymus genus, garden thyme (Thymus vulgaris L.) and common thyme (Thymus serpyllum L.) have economic importance. Three chemotypes of thyme are the object of this study - thymol, citral and geraniol. The main physical and chemical characteristics of the studied thymes are determined - humidity, proteins, fibers, lipids, essential oil and mineral composition. The chemical composition of organic substances in the essential oils of the different chemotypes was determined by GC – MS analysis. The distribution of the components by groups has been established. The yield of essential oil is highest in "French" and "Pagane" varieties. "French" and "German Winter" thyme oils are characterized by a high thymol content (36.98 % and 55.49 %, respectively), which determines their classification as thymol chemotype. In the essential oil of "Slava" variety, the main components are geraniol (28.89%), nerol (3.84%) and geranyl acetate (34.35%), which define it as a citral chemotype. Main components in "Pagane" thyme oil are geraniol (55.56%) and geranyl acetate (27.72%), defining it as a geraniol chemotype. The determination of the phytochemical characteristics of thyme aims to provide information on its condition, its suitability for storage and processing, as well as to determine the type and technological parameters for its processing.
An Investigation Of Service Quality Within Irish Franchised Motor Dealerships
Authors:   ,   Cork Institute of Technology, Atkinson Clive
Published: August 2024

"This study investigates service quality within franchised motor dealerships from the perspective of thirty-eight persons working in the roles of Dealer Principal, After-Sales Manager or Service Manager in dealerships operating under the Volkswagen group of brands in Ireland (VW, Audi, SEAT and Skoda). With approximately 2.3 million cars on Irish roads, more than two thirds of the Irish adult population encounter car service experiences on a regular basis. Regardless of brand or dealership type, the quality of vehicle service experience is paramount for customer retention. Despite this, however, service quality within Irish motor dealerships remains an under-explored area. Qualitative analysis in this study enabled new insights pertaining to the delivery of high quality services within franchised dealerships to be uncovered. A new conceptual model is proposed, which provides a structure through which excellent service quality can be achieved on a consistent basis. While the achievement of customer satisfaction through the delivery of high quality services is a priority within franchised dealerships, many issues impede efforts to achieve this objective. One element is the inadequacy of the existing 'one size fits all' approach to quality monitoring, which is used by the manufacturer throughout Europe. In particular, the structure of customer satisfaction surveys is a significant problem. Extensive coaching of customers is prevalent by front-line service staff within dealerships to stimulate specific customer responses to survey questions. In many cases, there is selective filtering of customers included for surveying in order to maximise positive responses. Financial implications imposed by the manufacturer, which are based on survey performance ratings, further exasperate the situation. A related finding exposes substantial inconsistencies and contrasting attitudes regarding the management of customer complaints within dealerships. Haphazard approaches to monitoring customer defection rates are also evident. The study presents findings, which demonstrate an over-reliance on reactive service quality checks, which are manufacturer driven. The study highlights the need for dealerships to establish more accurately, what Irish customers perceive as high quality service. The stipulations imposed by the manufacturer do not account for regional or local considerations influencing customer requirements. This limits the potential of dealerships to tailor aspects of services in a manner which may be more suited to the needs of their customers. Overall, the study shows that After-Sales operations, and service quality in particular, is increasingly recognised as vital for dealership profits and customer retention. This increased emphasis by senior management is fundamental for successful service quality improvements."

Authors:   ,   Cork Institute of Technology, Tobin Keelin
Published: August 2024

"The focus of this research is Ballymaloe Cookery School situated in East Cork, Ireland. This study seeks to understand the emergence of the cookery school, how this business has evolved over time and to investigate the impact it has had on the local area. Ballymaloe Cookery School was officially founded by brother and sister, Darina Allen (nee O’Connell) and Rory O’Connell in Shanagarry, Co. Cork in 1983. The findings examine the establishment of the cookery school as a family business and its attributes. Set amongst a rural landscape, close to the sea and surrounded by agricultural land, the school is well served by its organic gardens, farm, orchards and greenhouses. This is central to the defining ethos of Ballymaloe and sets it apart from sites of culinary learning elsewhere. In order to analyse the success and impact at Ballymaloe Cookery School in light of its values and early motivations, a qualitative approach based on semi-structured interviews was chosen. Analysis of the interviews resulted in a number of key findings. The results from this study indicate that, although the values underpinning Ballymaloe Cookery School and the fundamentals of cooking taught there remain constant, the school has undergone change, and innovation has been critical to its success. An aim of the empirical research was to explore the thoughts and perceptions of respondents regarding Ballymaloe Cookery School, in order to make conclusions about its impact and influence. Though the achievements of Ballymaloe Cookery School have resonance nationally and internationally, the impact of the cookery school in the region of East Cork is the focus of this study. Employment, support of local tourism, and support for local food producers were found to constitute the impact the school has locally. Additionally, the embeddedness of Ballymaloe Cookery School in the local community is considered significant for the region. The study also highlights the educational outreach conducted at Ballymaloe Cookery School, specifically The East Cork Slow Food Educational ‘Grow and Cook’ Project. Co-founder Darina Allen has been an activist in relation to specific issues of food justice, and a strong tradition of training and advocacy prevails at Ballymaloe Cookery School. The career paths of past students at the school are further evidence of this. In summary, this research discusses how Ballymaloe Cookery School, with Darina Allen at the helm, has benefited the local region of East Cork."
Cross-verified, Combined Methodologies For High Frequency Electrical Characterisation Of Electronic Packaging
Authors:   ,   Cork Institute of Technology, McGibney Eoin
Published: August 2024

Methodologies for cross-verified, wide bandwidth (50MHz-20GHz) electrical model extraction for as-manufactured electronic packaging and interconnection are presented. They are presented in the context that packaging and interconnection is now following a rapidly-evolving Moore’s-type Law in terms of new generations of packaging and interconnection materials, technologies and manufacturing processes. Significant frequency content is also increasing while, at the same time, final product cost constraints mean that packages and circuit boards must typically be manufactured using low cost materials and mass-manufacturing processes, often geographically remote, with their inherently higher levels of variability. Wide bandwidth signal integrity analysis cannot be performed during electronic system design without wide bandwidth electrical models for both packages and interconnects. However, existing methodologies for model extraction rely on time consuming individual techniques, laboratory- fabricated test samples, highly mathematical modelling approaches and specialised measurement equipment, they also offer limited verification of model accuracy and do not have the responsiveness or flexibility required in the face of rapidly evolving technology. The work presented here therefore had the objective of developing cross- verified methodologies for wide bandwidth electrical model extraction that, although based on sound scientific approaches, can be applied by the practicing engineer, using user-friendly modelling tools and standard laboratory measurement equipment, to test samples that can be fabricated using standard manufacturing processes. To achieve this, a detailed review was first completed of existing model extraction methodologies and their disadvantages relative to the demands of evolving packaging and interconnection technologies. By then initially reducing the problem to electrical model extraction for a small number of interconnection structures representative of those typically found in packages and boards, a draft methodology combining two modelling and two measurement techniques was proposed. The appropriateness of the methodology was then verified using test samples representative of modem packaging and interconnection: an ultra-miniature plastic chip-scale package and controlled impedance copper interconnections on very thin flexible polyimide. The methodologies yielded a cross-verified electrical model to 8GHz for the chip-scale package, the first known application of these multiple techniques to a CSP to this bandwidth. They also gave cross-verified whole-interconnect models to 20GHz, including copper and dielectric losses and the effects of moisture absorption, for the polyimide, the first known extraction of such models to this bandwidth for copper-polyimide interconnections.

Published: August 2024

"Micro electro mechanical systems (MEMS) applications in radio frequency (RF) and microwave electronics are revolutionizing the progress in wireless communications. In particular, MEMS switchable/tunable capacitors can facilitate the realization of multistandard software defined transceivers, offering better performance than existing solutions. In this thesis, characterisation and RF modelling of MEMS switchable/tunable capacitors and the technical requirements for their application in multiband wireless transceiver circuits in a software defined radio (SDR) are described. The first device considered is a curled cantilever capacitive switch, configured in both shunt and series configuration where the capacitance is limited to two stable states. The second device, referred to as a Hill shaped Zip-up Capacitor (FIZC), is a novel fixed beam structure where capacitance is continuously variable between the top beam and the central electrode. This thesis has developed a new and simple method for constructing 3D geometries of non planar MEMS structures in different actuation states for accurate electromagnetic modelling. This method combines mechanical and RF model tools and excellent model accuracy has been demonstrated for both MEMS switched and tunable capacitors. This model can be used to study the effect of surface roughness and can predict the air gap value in the lower contact electrode of MEMS capacitive structures. The RF performances of the capacitors were simulated by integrating the structures with coplanar waveguides with design improvements which extend the Isolation, capacitor tuning and Quality factor. In addition, the circuit with an equivalent lumped elements model is simulated and the CLR (capacitance, inductance and resistance) values are extracted. The applications of HZC capacitors in a reconfigurable impedance matching network are designed and analyzed. A simple lumped element impedance matching network was simulated at a single frequency with HZC tunable capacitors to match the impedance of power amplifier and the antenna and the results are presented."

Published: August 2024

Background: The present study was conducted to estimate gender from 2D:4D ratio and hand mor-phometry taken from participants by using machine learning (ML) algorithms.
Materials and Methods: The study was conducted retrospectively on 88 men and 96 women be-tween the ages of 18 and 30 who did not have any pathology, deformity or surgical interventions on their hands. Hand width (HW), hand length (HL), second digit length (2D), and fourth digit length (4D) of the individuals were measured as the right (R) and left (L) side by using digital calliper and recorded in Excel. In addition, the ratio between the second digit and fourth digit (2D:4D) of each individual was also recorded.
Results: As a result of ML modelling, 0.92 accuracy was obtained with Random forest (RF) algorithm. With RF algorithm, all of the 16 women and 18 of the 21 men in the test set were estimated accu-rately. With SHAP analyzer of RF algorithm, HW-L parameter was found to have the highest contri-bution in estimating gender. The accuracy rates of the other ML models used in the study were found to vary between 0.78 and 0.89.
Conclusions: It was found that 2D:4D ratio and hand morphometry measurements, which are fre-quently preferred in gender determination, have higher accuracy rate when examined with ML algorithms. In our study, we concluded that using 2D:4D ratio and hand morphometry in estimating gender provides accurate and reliable data.

The use of wind energy as one of the producers of electrical energy is done by converting mechanical energy into electrical energy from wind turbines, one of which is the savonius wind turbine. Savonius wind turbines in use are able to work at low wind speeds. This study aims to evaluate the potential of wind energy that can be generated by optimization in savonius wind turbines by measuring the power generated by varying the gap distance between Balde and turbine shafts and analyzing the most optimal power as a source of power generation on the coast of Sarmi Regency, Papua Province. The analysis method in this study is field surveys, wind speed measurements, power optimization, BHP and tool efficiency carried out with variations in the distance between the blade and turbine shaft, namely 5 cm, 10 cm and 15 cm. The results of this study stated that the most optimal and stable results on the power generated by the turbine as well as the BHP value and the best tool efficiency were a distance variation of 15 cm with an average power value produced (P0) of 15.55 Watts, an average BHP value of 0.56 Watts and an average efficiency value of 7.59%.
Optimization of Dehumidification Air Flow Distribution in Temulawak Tray Dryer with Computational Fluid Dynamics
Authors: Ridwan  , Apriansa Farul , Irawan Rudi
Published: August 2024

Temulawak (Curcuma xanthorrhiza Roxb.), a member of the Zingiberaceae family, has long been recognized as a medicinal plant with a moisture content approximately 80-90%. The high moisture content of temulawak renders it challenging to store for extended periods without drying. Temulawak is susceptible to heat damage due to the potential for thermal degradation of its internal components. Accordingly, it can be concluded that low-temperature and low-air-humidity drying conditions are required. Furthermore, one of the most suitable methods is the use of a dryer that incorporates a dehumidification process. The objective of this research is to develop a temulawak dryer design and simulation variations of the incoming velocity of air flow to obtain the most optimal drying chamber by incorporating a vertical airflow channel. A design and simulation for a temulawak dryer were created using the 2022 version of SolidWorks software (flow simulation modul). The design started from drawing two-dimension, then three-dimension, and determining boundary condition and meshing. A fluid temperature of 35.7°C and a relative humidity (RH) of 22% were used to model the drying process at varying airflow velocities of 1.5 m/s, 2 m/s, and 2.5 m/s. The drying chamber, with dimensions of 676 mm x 406 mm and height of 806 mm, was designed using the type AISI 304 and achieved the most optimal airflow distribution results at a velocity of 2.5 m/s, exhibiting a relatively higher fluid temperature than the other two airflow velocity variation.

Authors: Syafitri Ainil , Syarif Kemil
Published: August 2024

In some housing complexes with traditional electrical installation systems, electrical substations are often located in the middle of the housing complex or an area affected by flooding, causing the substation to be submerged and potentially endangering flood victims from being electrocuted. Based on these conditions, a remote voltage breaker system is needed to cut the electricity off automatically when the water level has passed a set point. This remote low-voltage electricity breaker system in flood areas is a tool for disconnecting the electrical system by detecting the water level. It can be monitored remotely based on IoT using an Android-based application. Using the HCSR04 Ultrasonic sensor to detect the water level in each container with a reading distance ranging from 2 cm to 450 cm, Ultrasonic sensor measurements will determine whether the detected water level is dangerous or not if the condition is dangerous, namely the detected water level is higher than the set point. Then, the MCCB will trip automatically. A microcontroller will process data and display the water level on the smartphone using the Blynk application. This tool uses a Node MCU-type microcontroller equipped with an ESP8266 WiFi module that functions as a regulator of the components used. The Blynk application will display water level monitoring data detected by the ultrasonic sensor in centimetre units. In the Blynk application, there is also a widget button that triggers the MCCB manually remotely. Several tests carried out on ultrasonic sensors produce the lowest error value of 1.49%, and the maximum trip time is 2.07 seconds.

The provision of Village Fund Allocation is a manifestation of the fulfilment of the village's right to exercise its autonomy it grows and develops following the growth of the village itself based on diversity, participation, original autonomy, democratization, community empowerment, and increasing the role of Village Government in providing services and improving community welfare as well as spurring the acceleration of regional development and growth. This study aims to determine the evaluation and strategy in village fund management with capital participation from Village Funds. This research uses qualitative approaches and methodologies in data collection as well as data presentation. The informants in the study were all Village Governments in the Konawe Regency area that had village-owned enterprises with the criteria of Independent and Developing Villages, Problem Villages, and Developed Villages. The data analysis process in this study went through three stages: The First is data classification. Second, data interpretation is an activity that combines the results of the analysis with statements to find the meaning of data collected in the field to answer problems and researchers' efforts to interpret data that can be taken by reviewing symptoms based on their point of view, comparison with research that has been done. Third, data presentation. The strategy of mentoring and coaching by the local government, especially through the Village Community Empowerment Office of South Konawe Regency to encourage the development of Village-Owned Enterprises in each village, has not been able to answer the challenges and problems in business development.

ABSTRAKCaO telah banyak digunakan sebagai katalis heterogen dalam reaksi transesterifikasi. Dalam penelitian ini, katalis CaO/zeolit alam telah berhasil disintesis menggunakan metode impregnasi basah. Campuran zeolit alam dan CaO diaduk di dalam refluks selama 90 oC selama 3 jam. Variasi rasio massa CaO/zeolit alam yaitu 5%, 10%, dan 15% yang selanjutnya diberi label CaO/NZ5%, CaO/NZ10%, and CaO/NZ15%, secara berturut-turut. Analisis menggunakan FTIR menunjukkan bahwa gugus-gugus fungsi zeolit alam tidak mengalami perubahan ketika pengembanan CaO dilakukan. Hasil ini didukung oleh hasil pengukuran menggunakan XRD yang menunjukkan kemunculan puncak-puncak difraksi dari mineral-mineral zeolit alam. Luas permukaan katalis yang diukur manggunakan N2 sorption analyzer menunjukkan bahwa semakin banyak jumlah CaO yang diembankan pada zeolit alam, semakin kecil luas permukaan katalis dari 15,201 m2/g sampai 12,928 m2/g. hasil tersebut mengindikasikan bahwa CaO menyusutkan ukuran pori zeolit, sehingga luas permukaan zeolit menurun. Analisis menggunakan metode titrasi asam basa menunjukkan bahwa kebasaan katalis meningkat seiring dengan meningkatnya jumlah CaO yang diembankan pada zeolit alam.Kata kunci : Katalis, CaO, zeolit alam, impregnasi basah.ABSTRACTCaO has been well known as a great heterogenous catalyst in the transesterification reaction to produce biodiesel. In the present study, synthesis of CaO/natural zeolite catalyst has been succesfully conducted using wet impregnation method. Impregnation was done by stirring the mixture of natural zeolite and CaO in reflux apparatus at 90 oC for 3 hours. The amount of CaO impregnated into natural zeolite were 5%wt, 10%wt, and 15%wt. These catalysts were then labeled as CaO/NZ5%, CaO/NZ10%, and CaO/NZ15%, respectively. Analysis using FTIR showed no change in functional groups when CaO was impregnated into the pores of the zeolite. This result was supported by the result of the XRD pattern which shows the appearance of natural zeolite diffraction peaks. Surface area measurement using N2 sorption analyzer showed the greater the amount of CaO impregnated into zeolite, the smaller the surface area of the catalyst from 15.201 m2/g to 12.928 m2/g. This result indicates that the CaO shrinked the pore size of zeolite, thus, the surface area of natural zeolite decreased. Acid-base titration result showed that the basicity of catalyst increased as the amount of CaO impregnated into natural zeolite increased.Keywords: Catalyst, CaO, natural zeolite, wet impregnation
