Genetic Risk Score for Prediction of Coronary Heart Disease in the Korean Genome and Epidemiology Study
Authors: Yun Hyunok , Lim Ji Eun , Lee Eun Young
Published: April 2023

Background: Using a genetic risk score (GRS) to predict coronary heart disease (CHD) may detect disease earlier. The current study aims to assess whether GRS is associated with CHD incidence and whether it is clinically useful for improving prediction using traditional risk factors (TRFs) as well as family history. Methods: Data from a total of 48,941 participants in the Korean Genome and Epidemiology Study were analyzed in the current study. The weighted GRS was constructed using 55 single-nucleotide polymorphisms based on published genome-wide association studies. The association of GRS with incident CHD was analyzed using Cox proportional hazard model. Discrimination and reclassification were assessed to demonstrate the clinical utility of GRS. The analyses were performed separately by sex. Results: After adjusting for family history and TRFs, GRS was significantly associated with CHD incidence in men; compared to the low GRS group, men in the high GRS group had a 2.07-fold increased risk of CHD (95% confidence interval [CI]: 1.51–2.85). In men, the combination of TRFs, family history, and GRS had better performance than TRFs alone (C statistics for TRF-only model, 0.66, 95% CI, 0.64–0.69; C statistics for combination model, 0.68, 95% CI, 0.65–0.71; category-free reclassification index, 15%). In women, however, there was no significant association between GRS and CHD and no improvement between models. Conclusions: GRS was associated with CHD incidence and contributed to a small improvement of CHD prediction in men. The potential clinical use of GRS may not outweigh the value of family history.
Clinical Signs of Kawasaki Disease from the Perspective of Epithelial-to-Mesenchymal Transition Recruiting Erythrocytes: A Literature Review
Authors: Oh Jin-Hee , Cho Soyun , Choi Jin A
Published: April 2023

Kawasaki disease (KD) is a systemic vasculitis affecting children younger than 5 years of age. Early period in life is marked by rapid somatic growth with cell proliferation and immaturity of the immunity with dominant innate immune system. Coronary complications in KD are the most common acquired heart disease in children, yet the diagnosis of KD still depends on the clinical diagnostic criteria. Glossy red lips and conjunctival injection are characteristic signs enabling pediatricians to make the initial diagnosis of KD; however, little is known why these are so characteristic. The diagnostic criteria of KD seem to be scattered in seemingly irrelevant body systems such as the eyes, lips, skin, and heart. KD is classified as a connective tissue disease. Recently, red blood cells (RBCs) have emerged as important modulators in innate immune response. RBCs are reported to participate in extracellular matrix remodeling and upregulating matrix metalloproteinase (MMP) expression in dermal fibroblasts. Also, fibroblast growth factors and microRNAs associated with fibrosis are drawing attention in KD. The cardinal signs of KD appear at the border of muco-cutaneous junction. Head and neck regions are abundant in tissues undergoing epithelial-to-mesenchymal transition (EMT). Interstitial carditis and valve insufficiency as well as coronary arterial lesions may complicate KD, and these lesions present in tissues that originated from epicardial progenitor cells by EMT. Having reviewed the recent research on KD, we presume that the signs of KD present at borders between keratinized and non-keratinized stratified squamous epithelium where the EMT is still ongoing for the rapid somatic growth where RBCs are recruited as an innate immune response and to prevent excessive fibrosis in mucosa. KD presents scarcely in adults with somatic growth and immune maturation completed. In this review, we attempted to explain the reasons for the clinical manifestations of KD and to search for a link among the diagnostic clues in the perspective of EMT during the somatic growth and immune system maturation in children with KD.

A Theory of Flexible Multimodal Synchrony
Authors: Gordon Ilanit , Tomashin Alon , Mayo Oded
Published: April 2023

Dominant theoretical accounts of interpersonal synchrony, the temporal coordination of biobehavioral processes between several individuals, have employed a linear approach, generally considering synchrony as a positive state, and utilizing aggregate scores. However, synchrony is known to take on a dynamical form with continuous shifts in its timeline. Acting as one continuously, is not always the optimal state, due to an intrinsic tension between individualistic and synergistic forms of action that exist in many social situations. We propose an alternative theory of flexible multimodal synchrony which highlights context as a key component that defines “pulls” toward synchrony and “pulls” toward segregation inherent to the social situation. Trait-like individual differences then sensitize individuals to these contextual “pulls”. In this manner, context and individual differences provide the backdrop to the emergence of flexible and dynamical synchrony patterns, which we consider adaptive, in several modalities– behavioral, physiological, and neural. We point to two main interpersonal consequences of multimodal synchrony patterns: Social and task-oriented outcomes. We delineate hypotheses that emanate from the theory which have not been articulated by previous theories and provide two empirical proofs-of-concept: In the first, we show how individual differences modulate the effect of context on synchrony’s outcomes in a novel dyadic motor game. In the second, we re-analyze previously reported data, to show how a ‘flexibility’ data-analysis approach to synchrony improves predictive ability when testing for synchrony’s effects on social cohesion. We end this review with guidelines for future synchrony research in light of the flexible multimodal theory presented
Lack of integrated number sense among college students: evidence from rational number cross-notation comparison
Authors: Schiller Lauren K. , Abreu-Mendoza Roberto A. , Fitzsimmons Charles , Siegler Robert , Thompson Clarissa A. , Rosenberg-Lee Miriam
Published: April 2023

Growing evidence highlights the predictive power of cross-notation magnitude comparison (e.g., 2/5 vs. 0.25) for math outcomes, but the underlying mechanisms remain unknown. Across two studies, we investigated undergraduates’ cross-notation and within-notation comparison skills given equivalent fractions, decimals, and percentages (Study 1, N=220 and Study 2, N=183). We found participants did not perceive equivalent rational numbers equivalently. Cluster analyses revealed that approximately one-quarter of undergraduates exhibited a bias to select percentages as larger in cross-notation comparisons. Compared with the other cluster of undergraduates who showed little-to-no bias, the percentages-are-larger bias cluster performed worse on fraction number line estimation and fraction arithmetic (exact and approximate), as well as reporting lower SAT/ACT scores. Hierarchical linear regression analyses demonstrated that cross-notation comparison accuracy accounted for variance in SAT/ACT beyond within-notation accuracy. Mediation analyses revealed a potential mechanism: stronger cross-notation knowledge equips individuals to evaluate the reasonableness of solutions. Together, these results suggest the importance of an integrated understanding of rational number notations, which may not be fully assessed by within-notation measures alone.

Authors: Jianyi Alicia , Sihag Vikrant , Schindler Christoph , Sharma Akash
Published: April 2023

Research in automatic recognition of human emotions has traditionally required the use of sensors placed on the body to collect physiological data, but recent studies have shown that heart rate can be estimated from videos of human faces by analyzing changes in RGB color during the cardiac cycle, a process known as photoplethysmography (PPG) signal extraction. This study introduces a novel method for classifying human emotions using contactless PPG signals. Various PPG signal extraction methods were tested on a popular emotional database, and a deep learning architecture that combined a 1D convolutional neural network (1DCNN) and a long short-term memory (LSTM) was utilized for classification. With a signal segmentation of 5 seconds, the method achieved a superior recognition rate for binary classification of valence and arousal, respectively. It is important to note that the primary aim of this study is to present a new technique for automatic emotion recognition using deep learning and contactless sensing of physiological signals.

Published: April 2023

Nepal is highly vulnerable to multiple geological, hydro and meteorological hazards in which floods, landslides, fires, avalanches, glacial lakes outburst floods, droughts and earthquakes are predominant. Nepal has also been experiencing outbreak of epidemics and pandemic having high morbidity and mortality. Every day, on an average, 2 people die due to recurrent disasters. Situated in seismic zone, Nepal is prone to earthquake, and it had experienced several episodes of earthquake having losses of human lives and physical infrastructure. Climate change attributing significantly in extreme weather conditions resulting heavy rainfall, drought, fire, and glacial lake outburst floods. The disasters events have severe impact in socio-economic and health of community people creating problem in access, disrupting supply chain, damage, and destruction of service delivery outlets. The main objective of this paper is to analyze the disaster situation in country, their impact and assess the role of government of Nepal and civil society organizations in reducing the disaster risks. This paper has been prepared by reviewing the secondary data mainly government, UN and I/NGOs reports and research articles. Marginalized groups of the society are hardest hit by the disasters. Investing resources in preparedness and risk reduction pays off in saving lives and properties, investing 1 NPR in DRR is equivalent to 18 NPR during post disaster situation. A whole of society approach where preparedness, risk reduction, response, recovery, and reconstruction go simultaneously in building resilience nations to disasters. Development work should mandatorily apply environmental impact assessment and do no harm principles. The government of Nepal has developed DRM Act, policy, and strategic plan. Accountability framework, risk governance and risk education play a critical role to achieve outcomes stipulated in the strategic plan.

Published: April 2023

In the Philippines, the lack of access to education of the youth is seen as one of the salient concerns of the economy, hence, affects the socio-economic development of the country. This problem occurs from the poor implementation of policies and programs and lack of government support and initiatives which evidently are the root causes of the slow improvement of the Philippine education system. This study aims to assess the implementation of Republic Act 7687 or the act that institutionalizes the science and technology scholarship in the country in relation to the actual experiences of the UPLB undergraduate DOST scholars. In support to this, the actors involved in the policy implementation including the DOST-SEI and UPLB-OUR were also considered in this study. The specific issues and challenges towards the DOST scholarships were also discussed in this paper to help in improving the effectiveness of the Republic Act 7687 as a policy.  To achieve the objectives of the study, the researchers employed both survey and structured interview research designs. Results showed that, in general, the student respondents are satisfied with how RA 7687 is being implemented at UPLB. However, the long and stringent process of the university’s registration and late issuance of Form 5 and delay in the release of scholars’ stipend/allowance became the major concerns of the respondents. Thus, researchers provided specific recommendations for DOST-SEI and UPLB-OUR to improve their system and process, specifically in managing the RA 7687 or the DOST Scholarship Program.

Published: April 2023

The purpose of the article was to study the analysis of technical errors during the performance of the classical jerk by young weightlifters at the stage of preliminary basic training. The study was conducted at the Kalnyshevsky State Secondary School No. 2 in the city of Romny and the Poltava State Secondary School No. 2.42 athletes of the pre-basic training stage aged 12-13 years in the category up to 45 kilograms participated in it. For the distribution of athletes into groups and, in turn, to identify the high average and low level of physical and technical preparation, we conducted control and transfer standards. Thus, in the course of our research, it was found that athletes with a low level of physical fitness should focus their attention on the technical component and work in the range of 60-70% from 5 to 7 repetitions per approach. The quality of execution of the elements of the classical jerk technique among young weightlifters aged 12-13 years of different groups according to the level of physical fitness was revealed. The highest quality indicators were obtained in group 1 (high level) of physical qualities in "athlete's interaction with the barbell" (5.1±0.52 points), "pre-acceleration" (5.1±0.45 points), "depreciation phase" (4.2±0.29 points), "final acceleration" (5.3±0.31 points), unsupported squat (7.0±0.32 points), supported squat (6.8±0.52 points ), fixation in a squat (6.7±0.45 points), standing up and fixation (6.3±0.29 points), which in most indicators is reliably better than in groups 2 (average level of physical qualities) and 3 (low level of physical qualities). Such a small percentage, and the corresponding high number of repetitions during the training process, will be able to eliminate many technical errors and shortcomings. Athletes with a low level of physical training, in turn, should pay great attention to exercises for the development of general and special physical training, improve strength indicators in auxiliary exercises, which, in combination with technique, will certainly improve their overall results.

The relevance of the problems of security of the state, society, enterprise and persons for Ukraine is not in doubt. Not only external negative factors (world pandemics, military conflicts, information propaganda, manipulation of public consciousness, cyber -terrorism, uncontrolled migration flows, aggravation and challenges for business entities and society, making it possible to look for and create new methods and tools for effective management. Unfortunately, internal factors that do not contribute to the financial security of the state and business: political instability, corruption, widespread practice of tax evasion and legalization (laundering) of proceeds obtained, uneven regional economic development and others. In view of this, the issue of financial security of business entities is of particular relevance. The issues of financial security of the enterprise are devoted to the study of foreign and domestic scientists. Paying the proper scientific and methodological value of existing scientific achievements, the problems of ensuring the financial security of the enterprise in war and post-war period remain poorly studied. The purpose of the study is to analyze the financial security of enterprises and ensure it in war and post - war recovery. The following research methods were used: comparison, analysis and synthesis, induction and deduction, generalization, systematization. The financial security management system is an orderly set of interrelated elements that form a single functional integrity intended for establishing and maintaining the optimal level of financial security. The coordination of the interaction of these elements largely depends on the success and efficiency of the functioning of the financial security management system of the enterprise.

Using the principles of the sharing economy as a method of increasing the efficiency of the enterprise in the post-war period
Authors: Mavrina Maryna , Belopolskiy Mykola
Published: April 2023

Relevance of the research topic. Today, a big problem for enterprises is a significant decrease in demand for their products. The main reason for this is the destruction of critical infrastructure because of hostilities, high rates of inflation, a decrease in the real income of the population, and a humanitarian disaster in the south and east of the country. Formulation of the problem. Using, for example, diversification as a method of increasing the efficiency of production and sales of products is no longer enough. It is necessary to look for and use new tools to protect enterprises from declining sales. The purpose of the article is to apply the principle of rational consumption to ensure the efficiency of the enterprise in the post-war period. Results of the article. It was determined that the principle of rational consumption together with the use of technological solutions of subscription systems open wide prospects for domestic enterprises. After all, using the principles of the sharing economy will make it possible to modernize business processes in such a way that enterprises can provide their services hundreds of times cheaper than before and at the same time be profitable, significantly expand their geography and create long-term financial relations with their consumers. Field of application of results. The conclusions of the article can be used mainly at enterprises in the sphere of wholesale and retail trade, manufacturing. Conclusions. The activity of enterprises in the field of trade and production is accompanied by certain difficulties. Sales of non-essential goods will decrease in the coming years. To prevent the bankruptcy of enterprises that do not belong to industries that provide basic human needs, the managers of these enterprises can introduce the principles of the sharing economy to create attractive, and most importantly, affordable and mutually beneficial conditions for cooperation with target customers. These principles can be applied both in the B2B (business to business) and B2C (business to consumers) sectors.
Отдельные особенности осуществления административных процедур и административного судопроизводства по Административному процедурно-процессуальному кодексу Республики Казахста
Authors: Карипова А.И. , Серикбекова С.Б. , Толеубеков А.Т.
Published: April 2023

В статье рассмотрены отдельные особенности административных процедур и административного судопроизводства при применении норм Административного процедурно-процессуального кодекса Республики Казахстан от 29 июня 2020 года за №350–VI–ЗРК (далее — АППК), введенного в действие с 01 июля 2021 года. Цель статьи — изучение особенностей административных процедур, административного судопроизводства и примирительных процедур при разрешении публично-правовых споров в рамках АППК, а также анализ отдельных проблемных вопросов его применения. При исследовании использованы общенаучные, частно-научные юридические методы познания. Авторами рассмотрены отличительные принципы осуществления административных процедур и процессуальные особенности административного судопроизводства. С введением в действие норм АППК упорядочен порядок проведения государственными органами как внутренних, так и внешних административных процедур, а также обособлено административное судопроизводство для разрешения публично-правовых споров с участием административного (государственного) органа либо его должностного лица. В статье затронуты проблемы пассивного, на начальном этапе, применения примирительных процедур при разрешении судами публично-правовых споров. На примере существующей практики предъявления государственными контролирующими органами исков в суд об использовании запретительно-ограничительных мер предложено передать рассмотрение такой категории дел из ГПК РК в АППК, поскольку это вытекает из публично-правовых отношений. Также имеет место неравное положение сторон публично-правового спора по срокам апелляционного и кассационного обжалования судебных актов по спорам публично-правового характера по АППК и ГПК Республики Казахстан. Вместе с тем, по-мнению авторов, введение института административных судов для рассмотрения административных дел и публично-правовых споров должно стать эффективным и действенным средством обеспечения защиты прав и законных интересов граждан и юридических лиц.
The role of law and moral in establishing countermeasures against sexual harassment
Authors: Saduova D.M. , Eremenko N.S. , Botagarin R.B.
Published: April 2023

Since sexual harassment is prevalent amongst women and becoming common amongst the middle school children, there is more demand for legal action. Surveys conducted by non-profit organizations show a high level of victimization, but there are often cases of constant concealment, silence about such facts of offenses. This article aims to discuss the role of law and morale in dealing with sexual harassment. On the one hand, it discusses the nature of legal definition of harassment and the difficulty in proving the act due to the presence of a subjective component. Inability to enforce the law will turn it merely into a symbolic measure. On the other hand, lack of law enforcement does not mean that the norm on sexual harassment will not have a deterrent effect. The existence of a legal norm will avert the crime, yet it will be difficult to measure the number of prevented offences. Equally important is to highlight that sexual violence is common place amongst the middle school children across the globe and gaining visibility in Kazakhstan. For that reason, the article discusses advantages and limitations of various interventions that aim to prevent sexual harassment in schools. With many interventions being of single program character, authors recommend systematic strategies that tackle harassment on the individual, family, and community level.
Предупреждение преступлений коррупционной направленности в процессе их расследования
Authors: Хлус А.М.
Published: April 2023

Рассмотрена деятельность следователя по предупреждению преступлений коррупционной направленности на этапе их расследования. Проведен анализ состояния, устремленности и тенденций данной деятельности. Обращено внимание на недостаточную эффективность регламентированных законодательством действий следователя в аспекте реализации мер предупреждения коррупционных преступлений. В соответствии с Уголовно-процессуальным кодексом Республики Беларусь следователь обязан выявлять причины и условия, способствовавшие совершению коррупционных преступлений. В дальнейшем он выносит представление об устранении выявленных причин и условий совершения преступления либо воздерживается от таких действий, руководствуясь своим усмотрением в пределах предоставленного права. В связи с этим предложено на уровне закона закрепить обязанность следователя принимать меры реагирования в случае выявления причин и условий совершения преступления. Автор указывает на вероятные направления следственной деятельности в связи с необходимостью предупреждения коррупционных преступлений. Одним из таких направлений представляется реализация предупредительных мер индивидуального характера в отношении участников уголовного процесса. Объектами предупредительного воздействия, осуществляемого в процессе производства следственных действий, выступают подозреваемые (обвиняемые), а в ряде случаев — и иные участники уголовного судопроизводства. Иное направление осуществления мер предупреждения коррупционных преступлений разворачивается за пределами расследованного уголовного дела. В этой ситуации объектами предупредительно-профилактической работы следователя являются организация (учреждение), в котором произошло коррупционное преступление, её руководящий состав, а также неопределённый круг иных лиц, профессиональная или служебная деятельность которых осуществляется в данной организации (учреждении). В качестве самостоятельного направления противодействия коррупционным преступлениям автор предлагает совместную профилактическую деятельность, участниками которой выступают следователи, расследовавшие уголовные дела о коррупционных деяниях, и специализированное подразделение Следственного комитета. Осуществление предупредительнопрофилактической деятельности по указанным направлениям представляется возможным на нормативно-правовой основе, что предполагает совершенствование действующего процессуального законодательства.

Published: April 2023

In the work the analysis of mathematical models of multi-frequency piezoresonance oscillatory systems is carried out. It is indicated on the essence of the phenomenon of multifrequency excitation, as a normal physical property of quartz resonators. However, for the tasks of constructing highly stable self-oscillating systems as a source of reference oscillation, this property of the CR is undesirable, moreover, it is struggling with all possible methods. As a result of the analysis of mathematical models of multifrequency oscillation systems, it is established that none of them allows to fully study the dynamics of multifrequency oscillation systems under conditions of vibrational destabilizing effects, which requires their further study. Proposed own approach to solving problems of simulation of multi-frequency PCBs.
ALGORITHM FOR DETERMINING THE TORQUE OF ELECTRIC MOTORS USING INDIRECT MEASUREMENT METHODS
Authors: KVASHUK Dmytro , YASHCHUK Olesia ,   National Aviation University
Published: April 2023

Indirect torque measurement methods can be performed in a variety of ways, depending on the specific situation and available tools. One such way is to measure the displacement, or speed of rotation of the shaft and use this information to calculate the moment using the moment of inertia equation. For this, it is necessary to know the moment of inertia and the angular acceleration, which can be measured using a gyroscope or accelerometer. Another way is to measure the voltage and current in the electrical circuit connecting the motor and the power source by determining the power of the electric motor. However, indirect methods of measuring torques of electric motors are based on the measurement of other physical parameters that correlate with torque, such as current, voltage, rotation frequency, etc. These methods are often used because of their cost-effectiveness and ease of implementation, but they have some drawbacks. In particular: indirect methods are usually less accurate than direct methods because they depend on mathematical models and correlations between different parameters, which may be imprecise or incomplete; parameters that are measured by indirect methods may be influenced by external factors, which may affect the accuracy of measurements; calibration of devices is usually carried out in laboratory conditions, so the results may not reflect real operating conditions; the mathematical models used to determine the torque may be non-linear. This can lead to errors in measurements, especially at high or low torque values; indirect methods do not provide direct feedback about the real torque, which can lead to delays in process regulation and control. This can be critical for some applications where fast and accurate torque control is essential; indirect methods may be less efficient or unsuitable for some types of electric motors or applications. For example, when using high-frequency or multiphase motors, indirect methods may not provide sufficient accuracy or stability of measurements. The article examines algorithms for determining the rotational parameters of electric motors using indirect measurement methods. An analysis of the characteristics of electric motors according to their energy data was carried out. The measurement possibilities are determined based on the functional dependence of the torque on the power of the electric motor and the speed of rotation of its shaft. The characteristics of the power components are studied and the results of their simulation are given. An analysis of the methods of determining the angular velocity and angular acceleration of the electric motor shaft was carried out, and the role of these parameters in the determination of the torque was investigated. A two-channel network-type information and measurement system is proposed, which allows data collection and their visualization, where one channel is used to measure power, the other to measure shaft rotation speed.

Published: April 2023

The methods of multiple access with multiplexing of resources are studied and the advantages and disadvantages of orthogonal multiple access (OMA) and non-orthogonal multiple access (NOMA) are considered. A comparative analysis of data transmission schemes in the radio network was also performed, taking into account resource planning, in particular: transmission with service information and transmission without service information. The structure of the NOMA uplink receiver based on OFDM signals is proposed. The peculiarities of providing supermassive connection within limited radio resources on the basis of grantless access using NOMA have been studied. At the same time, methods of solving the problems inherent in the current application of GF-transmission and NOMA in the implementation of supermassive connection to the access network based on 6G technology were considered. Prospects for the introduction of an artificial intelligence transmitter based on a multiple access transmission scheme with low cost, low PAPR, low delay, high reliability and wide connectivity are determined. And features of artificial intelligence receiver design using artificial intelligence / machine learning techniques that can play a role in facilitating MUD design for NOMA are also considered.

The quality and reliability of repaired machines depend significantly on the perfection of the technological processes of disassembly, cleaning, surface preparation and assembly. The analysis of methods and modern designs of equipment and machines for cleaning and washing pollution showed the possibilities, advantages and disadvantages of various methods and designs of equipment. The main interest for the practice of creating vibrating machines for cleaning and washing parts contamination in small-batch and single-type production when repairing machines is to establish the type of dependencies between the main technological parameters, such as the dynamic pressure of the working environment, the size of the working bodies, their speed, the angle of attack, design parameters and modes of operation of the drive of vibrating machines. The design of a vibrating machine for cleaning contamination with a stream of solid particles and washing parts during equipment repair is proposed, which consists of two modules: a cleaning module with a pulsating submerged jet with solid particles and a module for washing contamination with a pulsating submerged jet of washing liquid. Experimental studies were conducted to measure the maximum pressure of a pulsating jet with a non-return valve installed, depending on the change in the frequency of oscillations of the drive and the change in the diameter of the nozzle. The results of experimental studies of changes in the pressure of a pulsating submerged jet depending on the frequency of oscillations of the drive are presented, which showed a two-fold increase in the maximum pressure of a pulsating submerged jet when using a non-return valve that connects the cleaning bath with the pulsation chamber. In order to reduce the occurrence of a significant number of cavitation bubbles in the pulsation chamber for the non-return valve, it is important to calculate the maximum total area of the holes and their number, based on the volumetric flow of liquid through it during the oscillation period. The determined valve operation time is 0.014s. says that its performance is ensured at frequencies from 0 to 70 Hz of vibrations of the vibration drive. The methodology and example of calculation of the non-return valve of the module of the vibrating machine for cleaning pollution by the flow of a pulsating jet of liquid with solid particles are presented.

Goat, is one of the most consume meat in Indonesia, it provides much nutrition to the eater and highly recommended by several nutritionist. One of the most critical part in breeding goats, is feeding them, this process is one of the most time consuming and takes a lot of effort, as the food preparation requires a lot of item to mix. Breeder, nowadays mostly feed their goat with “dry food” which are mostly consist of concentrate, this process unfortunately still done manually which, not only takes time but also some chances of potential hazard because most of the concentrate are heavy and huge. This research takes place in Rejodani District in Sleman Regency thus the sample and population of the research are goat breeder around the area. Using Quality Function Deployment method, authors intended to create a new food processing tools for food preparation of the goats. Using the concept screening and selection, out of 3 proposed design, the best design is chosen, followed by validation process to the respondents of the research. The final design of the food processor is the one that could increase productivity of the breeder and less chance of hazard.
