Thermophilic bacteria are a source of bioactive compounds that have many benefits for human life. One of them is as a source of antimicrobials. This research aimed to identify and characterize the promising thermophilic bacterial isolates by analyzing bioactive compounds and their potential as antimicrobial agents. Thermophilic bacteria with the code LBKURCC were taken from the collection of the Biochemistry Laboratory of the University of Riau. Forty-four purified strains of thermophilic bacteria were tested for antimicrobial ability. These thermophilic bacteria were taken from hot springs located in the Sumatra provinces of West Sumatra and Riau. Strain LBKURCC218 isolated from Rimbo Panti hot springs in West Sumatra was chosen to further investigate antimicrobials production. Isolates of hot spring bacteria that produced the highest antimicrobial were identified by comparing the similarity of the 16S rRNA gene sequences. BLAST result and phylogenetic tree showed that the selected thermophilic bacterial strain was similar to Bacillus paramicoides with the similarity index of 99.93%. Analysis of bioactive compounds of the ethyl acetate extract of liquid cultures of B. paramycoides LBKURCC218 showed the best producer of antimicrobial compounds compared to other isolates. The most identified compounds from the ethyl acetate extract were Dodecanoic acid, representing 23.62% of the total compounds, followed by 11-Dodecanoic acid at 17.84%. Ethyl acetate extract of B. paramycoides LBKURCC218 has a high inhibition zone against Escherichia coli, Staphylococcus aureus, and Candida albicans.

This study was intended to obtain white rust (Puccinia horiana) disease resistance Chrysanthemum transformed with wasabi defensin gene through mediation of Agrobacterium tumefaciens from three explant sources, i.e., leaf, lateral shoot bud, and internode. Observations were made on transformation efficiency, PCR analysis, in vitro and ex vitro disease resistance tests. Results showed that efficiency of transgenic callus and shoot regeneration was found both highest from lateral shoot buds (57.5% and 50.0%, respectively). PCR analysis showed that three putative transgenic plantlets from lateral shoot buds and one from leaf explant were putative transgenic carrying the wasabi, hpt, and nptII genes. Rooting test showed that the highest number of rooted plants was found in treatment of hygromycin (Hg) 25 mg L-1 (81%) and lowest was in treatment combination of kanamycin (Km) 50 mg L-1 + Hg 25 mg L-1 (25%). In vitro disease resistance test with sorus inoculation of P. horiana, directly on the leaves, resulted in 20 resistant plants out of 30 putative transgenic plants (66.67%). Ex vitro testing on adult plants of the same samples in a confined closed greenhouse (CGH) resulted in average of 80% transgenic Chrysanthemum plants were resistant, whereas in control plants caused white rust disease symptom.

The giant honey bee Apis dorsata has a vast distribution in Asia, including in the Indonesian archipelagos, whereas A. d. binghami is endemic to Sulawesi Island. This research aimed to analyze the variations of landmarks in wing venation of A. dorsata from Sumatra, Belitung, Java, Sumbawa, Moluccas islands, and A. d. binghami in Sulawesi, based on geometric morphometric analysis. Nineteen landmarks from 200 wing venations were analyzed using Thin Plate Spline software. Our study found landmarks 16 and 17, known as Cubital Index in traditional morphometrics, contributed to the wing shape of A. dorsata and A. d. binghami Among all samples, these two landmarks show high displacement in the wing shape of A. d. binghami in Sulawesi and A. dorsata in the Moluccas. On the contrary, we found that the Sumatra, Belitung, and Java Apis dorsata revealed low displacement in the deformation grid; resulting in their shapes being more similar to the reference landmark. The variations of wing shape separate A. d. binghami from Sulawesi and Sumbawa in the Principle Component Analysis and agreement with the Neighbor-joining tree. Therefore, the geometric morphometric based on landmarks of wing venation is a powerful tool to discriminate the subspecies level of A. dorsata.

Vücuttaki kullanım yerlerine bağlı olarak implant üretiminde kullanılan malzeme türü değişmektedir. CoCr alaşımı yüksek dayanım, aşınma ve korozyon direnci gibi avantajlarından dolayı kalça implantlarında oldukça sık kullanılmaktadır. Gelişen eklemeli imalat teknolojisi sayesinde farklı yoğunluklara sahip gözenekli kalça implantları üretilebilmektedir. Üretilen gözenekli kalça implantları daha düşük elastisite modülüne sahip olduğundan kemik ve implant arasında oluşan gerilmeler azaltılabilmektedir ve böylelikle implant üzerinde meydana gelen gevşeme, kırılma, deformasyon gibi problemler ortadan kaldırılabilmektedir. Tasarlanan iskelelerin, yeni oluşturulan hücrelerin iç mimarisini desteklemesi gerekir. Bu nedenle vücutta kullanılan iskele yapılar kemiğin mekanik dayanımını korumak zorundadır. Bir kemik iskelesinin elastik modül, basınç ve gerilme dayanımı, maksimum gerilme ve bükülme modülü gibi mekanik özellikleri kemiklerin ve sert bağ dokularının yerine başarıyla geçebilecek şekilde olmalıdır ve hastanın kullanımında ya da düzenli faaliyetleri sırasında çökmemelidir. Bu yüzden yapılan bu çalışmada farklı birim hücre modelleri kullanılarak, hücre yoğunluğu ve şekil geometrisi belirlenip basma testine tabi tutulmuştur.

Published: July 2022

This study aims to examine the ornament parts of the traditional ceilings, one of the essential elements of the space with physical and psychological aspects, in terms of design methods and approaches. In this study, the ceilings of the houses have been discussed in the Safranbolu region, which was chosen as the study area. Star-formed ceiling rose ornament, which is one of the indispensable components of these elements and is widely used in these houses, has been evaluated by shape grammar implementations that are commonly both generative and analytic tools for assessing design languages. By determining generation rules, a design process has been defined. With these rules, by using samples of present ceiling ornaments, variations have been generated in the frame of different scenarios. The richness and innovative sustainability of Star-formed ceiling rose ornament are demonstrated by the proposal of an analytic and generative approach based on inferences from traditional implementations. This study makes contributions to the literature by offering an alternative process to imitations and iterations of traditional architectural components and by enriching the design language of the craft implementations

Published: July 2022

Design studios play a significant role to train the students in architecture programs. Studios call as core modules in programs that are supposed to apply the knowledge, skills, and abilities of the students for the design’s topic, process, and project. However, the design process follows a tradition in studios based on project design than research activities. The research applied the qualitative content analysis method to analyze the design studio modules' descriptions. The finding of the research identifies that the content of the modules' descriptions does less adapt to research activities. Despite the inductive content explanations, the analysis activities are far from a comprehensive research approach due to the missing aspects in the content of the modules descriptions in the curriculum. In conclusion, research activity is an essential segment of architecture education that has been missing in the curriculum due to the time and location. However, complexity, uncertainty, and variety in the design context remind the necessity of integrating design studio with real-world studio activities through research orientation.

The trend of early retirement has increased over the last few years. Many teachers applied for early retirement after experiencing a ‘strict’ academic environment in the schools. The purpose of the present study was to grasp an in-depth understanding of the early retired teachers' life in the province of Punjab, Pakistan. The study aims to seek the answers to the questions: How did the school teachers decide to take early retirement and what were their personal and social activities after early retirement? Participants’ description of life after early retirement was explored through narrative research while interviewing fourteen teachers who took retirement at least three years before retiring and approached through snowball sampling. The results were presented thematically (business to live happily, health and home, and joy and freedom). Most participants started or expanded their business, lived a happy life, paid attention to health and enjoyed freedom after early retirement. The research will help understand teachers' lives after taking early retirement through their life experiences and their activities. The study has implications for the school department on how they can better the teachers' social and personal lives during the service to enjoy life and feel happy while working in schools.

Preparing young people for the future of work is one of the tasks of paramount importance. Based on the focus of modern education on the formation, in particular, of general competencies, the features of the interaction of the teacher with students in mastering the educational material are pointed out. The solution to the problem of the formation of general competencies of students from the standpoint of the eﬀectiveness of this process is possible when the teacher uses methods for organizing the activities of students that meet certain requirements (criteria for enriching subjective experience).

A theoretical analysis of the scientiﬁc, pedagogical and methodological literature was carried out, a generalization was made and the systematization of the studied material was carried out, which made it possible to identify the conditions for the successful organization of students’ activities and indicators of the formation of general competencies of future specialists. In connection with the need to develop methodological support for the organization of students’ activities from the standpoint of developing general competencies, a procedure for improving the method of organizing students’ activities chosen for a speciﬁc learning situation is presented, which allows the teacher to model new techniques based on a speciﬁc goal. On the example of studying educational mathematical problems, it is shown how the procedure for improving the technique chosen by the teacher is carried out. The results obtained can be useful not only for teachers of mathematics, but also for teachers of other academic disciplines, as well as for creating a lecture course for the advanced training program for educators.

Published: July 2022

The development of an ultrasonic ﬂ aw detector receiving unit for rail monitoring includes theoretical and practical studies. Special attention is paid to the experimental determination of the characteristics of the ultrasonic piezoelectric sensor and the description of the receiving-amplifying path. A mock-up sample of an ultrasonic ﬂ aw detector allows checking rails for defects and gives a tangible gain in dimensions compared to bulky analogues.

The theoretical methods used were based on the principles of electrical engineering, electronic engineering, graphical analysis and the theory of automatic control.

Experimental studies of the piezoelectric sensor allowed us to determine its main resonant frequency. The correct choice of parameters of the ampliﬁer unit ensured accurate and reliable operation of the device. Practical tests of the ﬂ aw detector using a special buﬀer sample of the rail made it possible to adjust its sensitivity

The input ampliﬁer of the microvoltmeter V3-40 is taken as the basis of the receiving and amplifying path of the ﬂ aw detector. The device includes the possibility of its use in conjunction with the converter. The structural diagram of the ﬂ aw detector is presented. The electrical circuit of the input divider with the selection of the necessary resistances and the electrical circuit of the eﬀective value meter with a description of all its elements are described.

Operating modes and electronic circuits are selected according to reference data, taking into account their high reliability of operation. The use of analog integrated circuits in the circuit solution made it possible to increase the reliability and accuracy of the ﬂ aw detector device, simplify its adjustment, reduce zero drift and improve the quality of the output signal.

Implementation of the spatial voltage vector modulation algorithm using an artificial neural network
Authors: Chol Kim Gum , Song Kim Gum
Published: July 2022

An algorithm for space vector pulse width modulation (SVPWM) based on an artiﬁcial neural network is proposed.

In calculating the action time of the voltage vectors according to the traditional SVPWM algorithm, the values of the relative phase angle on the sectors are used as variables, which causes diﬃculties in their calculation.

To overcome these shortcomings, mathematical models have been compiled that determine the opening time of the power element by the absolute phase angle on the inverter converter. Since mathematical models have different types of calculation formulas for sectors and it is impossible to express them in an unambiguous formula, to eliminate these diﬃculties, a function was built using an artiﬁcial neural network, with which you can generally determine the opening time of a power element in phases A, B and C.

Regardless of the sectors, the SVPWM algorithm sets the opening time of the power element according to the phase angle θ on the inverter converter.

The generalized ability of the artiﬁcial neural network and its accuracy, as well as the simulation operation time in the MATLAB environment, were tested.

The proposed method makes it possible to achieve high speed control accuracy and signiﬁcantly reduce the operation time.

When controlling the traction drive of an electric rolling stock with an asynchronous traction motor, it is possible to reduce the regulation period, as a result, the traction capacity of electric locomotives and metro electric trains with vector control or with direct torque control increases by about 1.1–1.2 times.
Optimization of the physical parameters of the organization of databases

Published: July 2022

The main task of the transport system is the most complete satisfaction of the needs of business entities and the population in transportation, reducing the time of delivery of goods and transportation of passengers on the basis of a qualitative increase in the capacity of the entire transport system. This problem is solved with the help of computer technology and new information technologies in transport management systems. The most demanded is the database technology implemented in modern automated transport management information systems.

Given the exponential growth in the volume of databases used, strict time limits for real-time management decisions in transport management systems, the task of minimizing the time to execute information queries in the database is of particular relevance.

The execution time of information requests is influenced by the methods of physical storage of databases. To solve the problem of minimizing the execution time of information requests, it is necessary to determine the physical parameters that affect the efficiency of database processing.

An external memory simulation model is described for optimizing the physical parameters of database organization, based on the exchange procedures implemented in modern database management systems between external and operational memory upon information requests. As a key optimization parameter, a memory block reservation factor is substantiated, which allows minimizing the number of slow accesses to external memory.

The rationality and adequacy of the proposed model in the process of research is confirmed by the results of simulation modeling.

Published: July 2022

Over the past two years, due to the spread of the epidemic and the restrictions imposed, state borders have been closed, restrictions on the movement of people and goods have been established, supply chains have been disrupted and, as a result, consumer demand and purchasing power have decreased. These events had a negative impact on the revenues of operator companies. Transportation of goods is carried out by diﬀerent modes of transport. The choice of transport depends on many factors: the volume of cargo transported, the location of enterprises of producers and consumers, the degree of development of the transport infrastructure.

At present, the task of reducing the transport component in the price of goods and, accordingly, the costs of operating companies of railway rolling stock during the transportation of goods is becoming urgent. This can be achieved by outsourcing some of the work performed by rolling stock operating companies.

The conditions for the termination of work by the rolling stock operator are considered. A tool for analysis is presented, an assessment of the eﬀectiveness of outsourcing is made. The use of outsourcing will allow railway rolling stock operators to reduce costs for non-core activities, to focus on those processes that directly bring proﬁt.
First play about the railway
Authors: Bikeeva I. A.
Published: July 2022

The article considers the ﬁrst essay in Russian literature in which the image of the railway appears. We will talk about the comedy-vaudeville P.S. Fedorov “A Trip to Tsarskoye Selo by Rail” (1838). In the future, this image became one of the key in Russian culture at the turn of the 19th–20th centuries, writers such as L. Tolstoy, Nekrasov, Kuprin, Leskov and others addressed it, endowing it with diﬀ erent meanings — from positive to sharply negative and all the more interesting to learn about the origins of its occurrence. The author of the article concludes that in Fedorov’s comedy, the railway is a locus that determines the plot of the play and the happy resolution of the conﬂict. In general, the railway is considered by the author of vaudeville as a miracle and a great achievement of progress, and almost every character in the play utters praise words to her. Attention is also paid to the ﬁgure of the author of the play, Pavel S. Fedorov, one of the largest playwrights and translators, who for 26 years led the repertoire of the St. Petersburg theaters, whose work was forgotten in the 21st century. The facts outlined in the article may be useful for interdisciplinary connections in the lessons of history and literature, as well as special disciplines for future railway workers.

Bu çalışmada yeni sosyal ekonomi anlayışında iş gücü tercihlerinde bilişsel beceriler ve kadın işgücü sorunsalının Türkiye ekonomik büyümesindeki yerinin belirlenmesi ve sonuçlarının ortaya konulması amaçlanmıştır. Çalışma, Türkiye istatistik Kurumu (TUİK) veri tabanı ile Eurostat veri tabanı 2015-2019 ve 2008-2020 dönemlerine ilişkin veriler ışığında gerçekleştirilmiştir. Araştırmada daha çok son 5 yıllık süreçte gelinen durumun belirlenmesi ve değişimlerin vurgulanması amaçlanmıştır. Temel istatistiki göstergeler eşliğinde kadın çalışanların eğitim durumu için Türkiye’deki mevcut yapı ayrı değerlendirilmiş, bunun yanı sıra Türkiye ve AB 27 ülke gurubu için sadece eğitimin etkileri karşılaştırılmıştır. Bununla birlikte önemli parametrelerin ölçülmesinde temel araçlar olarak; işveren olarak kadın çalışanlar, işgücüne katılımı, tarım ve tarım dışı sektörlerde kayıt dışılıkları ve aile işçisi olarak çalışanların istihdam içindeki oranı bakılmıştır. Ayrıca yarı-zamanlı çalışanlar, mesleki guruplarına göre istihdam edilme konumları ile 3 yaşın altında çocuğu olan/olmayan kadın çalışanlar gibi değişkenlere bakılarak durum değerlendirmesi yapılmıştır. Çalışmanın sonucunda, Türkiye’de yüksekokul, fakülte ve yüksek lisans ve doktora mezunu kadın sayısının giderek artış gösterdiği ve Türkiye’nin AB 27 ülke gurubuna nazaran bu anlamda daha ilerde olduğu görülmüştür. Kadın işgücünün son yıllarda eğitim düzeyinin artmasıyla çok daha farklı iş kollarında istihdam edildiği görülmektedir. Genellikle kadınların tarım ve yarı zamanlı ev tipi işlerde çalışma hayatında yer aldığı görülmesine rağmen bilişsel becerileri nedeniyle de daha çok hizmet sektöründe yoğunlaştıkları görülmüştür. Söz konusu çalışma alanları nedeniyle işgücüne katılım oranı içinde son beş yılda kadın sayısının erkeklerin yarısına kadar ulaşması kanıtlar nitelikte olduğu söylenebilir.

CREDIT RISK AND PERFORMANCE EVALUATION OF COOPERATIVES IN REGION XI USING DATA ENVELOPMENT ANALYSES (DEA)
Authors: Cruz Edgardo D. , Sabado Jesson Rey F.
Published: July 2022

This paper illustrated the methodology that indicates how the Standard and Negative Data Envelopment Analysis (DEA) techniques can be applied to predict likely failures in cooperatives. The general objective of this study is to develop a model that will provide a reasonably accurate means of evaluating the creditworthiness of cooperatives in Region 11 using information obtained from the Financial Statement submitted to the Cooperative Development Authority. The results showed that the Standard DEA could predict cooperatives that are likely to fail in combination with the Negative DEA. The proposed methodologies identify companies with a high risk of going bankrupt by looking at their total financial situation.

TECHNICAL EFFICIENCY ESTIMATES OF COFFEE PRODUCTION IN DAVAO CITY, PHILIPPINES: A DATA ENVELOPMENT APPROACH
Authors: Sabroso Leomar M. , Tamayo Adrian M.
Published: July 2022

The Philippine coffee industry is dominated by small-scaled farm households. This study was conducted to measure the technical efficiency of coffee production in Davao City using Data Envelopment Analysis. The study also determined the factors that contribute to the technical efficiency of coffee farms using Logistic Regression. Among the 166 respondents obtained, the study revealed that only 11 DMUs are technically efficient operating under constant return to scale while 154 and 1 were technically inefficient operating under increasing return to scale and decreasing return to scale, respectively. This means that input such as farm size, labor, number of coffee trees, age of coffee trees, fertilizers and pesticides has to be adjusted in order to reach the frontier to be technically efficient DMUs in which coffee farms are the potential to increase production if provided with appropriate support. Furthermore, to achieve bias-corrected DEA technical efficiency scores, Bootstrapping was done and later used for regression. Meanwhile, the logistic regression results revealed that there were significant relationships between technical efficiency and socioeconomic such as Age of Household Head, Sex, Access to Credit, Cropping System, Technology, and Coffee Variety. However, the logistic regression also revealed the factors that have no statistically significant relationship in the variables such as Education, Farm Experiences, Household Size, Extension Services, and Off-farm Activities.

MICRO-COUNSELING SKILLS MASTERY OF GUIDANCE COUNSELORS AT JUNIOR HIGH SCHOOLS
Authors: Saputro Henri , Wangid Muhammad Nur
Published: July 2022

The purpose of this study was to determine how far the micro-counseling skills mastered by Guidance Counselors (counselor) at the Junior High School (SMP) in Kulon Progo Regency. The subject of the study were guidance counselors/teachers at the Junior High Schools in Kulon Progo Regency with a proportional sample of 33 teachers. Research data were collected using a questionnaire instrument and analyzed using quantitative and qualitative descriptive techniques. The results of the study show: 1) All guidance counselors believe that the use of counseling skills can improve the quality of counseling services, but only the majority of guidance counselors use these skills. The micro counseling skills used by most of the Kulon Progo guidance counselors are attention, opening, acceptance, direction, strengthening, advice, summary, and termination. 2) A small number of guidance counselors admitted that they had never received micro-counseling skills material, either when they were still students in college or when they had entered as practitioners or guidance counselors. Suggestion from this research is that guidance counselors need to take part in training to increase their capacity for mastering micro-counseling skills. The training can be in the form of role-playing with colleagues or practice handling cases directly with the assistance of a competent supervisor. Professional organizations, universities, and schools need to provide support to guidance counselors in efforts to develop and improve the competence of micro-counseling skills.
