Authors: DN Bukbuk
Published: September 2022

Several studies in both humans and animals in Nigeria have presented evidence for the endemicity of CCHFV in Nigeria. In spite of the aforementioned, there has been no confirmed human case of CCHF infection in Nigeria. We present a study giving the first serologic and virological evidence of CCHF in a 15-year-old female, She was admitted in March 2012 into the female medical ward of the University of Maiduguri Teaching Hospital, a tertiary health facility in northeastern Nigeria with a 6 day history of fever, body pain, bloody diarrhoea, and epistaxis. She resides in a peri-urban settlement in old Maiduguri located not far from a major municipal abattoir in Maiduguri, the capital city of Borno state, Nigeria. The abattoir serves as the major animal slaughter house within Maiduguri city. Animals (Camel, Cattle, Goat and Sheep) are brought from within the Stat Borno), neighbouring states and mostly from neighbouring countries such as Cameroun, Chad, Niger, and as far as Sudan, Central Africa. The RNA extracted from this sample (N428) was further characterized by next generation sequencing (NGS) which resulted in complete S, M, and L viral RNA segment sequences. Phylogenetic analysis clustered the S-segment in the Africa 3 clade or phylogenetic group. The S-segment open-reading frame showed close homology with a previous isolate of CCHFV from Nigeria (IbAr10200), as well as isolates from Mauritania (ArD39554) and South Africa (SPU415/85 and SPU128/61/7). The M and L clustered closely with the Sudan ABI-2009 isolate and the Nigeria IbAr10200. The L, M, and S sequences were submitted to GenBank with accession numbers KX238956, KX238957 and KX238958 respectively. This genomic analysis provides the first published evidence of a human case of CCHFV in Nigeria and its phylogenetic context.
Understanding Emotional Roots of Human Immune System
Authors: R Verma
Published: September 2022

Decades of research has provided evidence that various psychological factors have a huge impact over the immune system which systematically stimulate it to give positive or negative responses and can time to time show several levels of modulations. These modulations or responses may enhance or may adversely affect the immune function of an individual. This review article focuses on affects and its roots to the human immune system, supported by various studies conducted in different times. The paper also discusses all the possible pathways by which emotion can connect with the immune function and vice-versa, how stress can affect the immune response as well as how the elements of psychological factors can modulate the immune function of an individual
Quantitative COVID-19 Infectiousness Estimate Correlating with Viral Shedding and Culturability Suggests 68% Pre-Symptomatic Transmissions
Authors: MK Prakash
Published: September 2022

A person clinically diagnosed with COVID 19 can infect others for several days before and after the onset of symptoms. At the epidemiological level, this information on how infectious someone is lies embedded implicitly in the serial interval data. Other clinical indicators of infectiousness based on the temporal kinetics of the viral shedding from the nasopharyngeal swabs and sputum show the former decaying weeks sooner than the latter. In this work, we attempt to provide a better quantitative estimate for the temporal infectiousness profile using serial interval data from a combined 1251 individuals reported in the literature. We show that the infectiousness profile which we calculate correlates well with the viral shedding kinetics from nasopharyngeal swabs (ρ=0.97, p=0.00) and cultivability (ρ=0.83, p=0.01). The profile suggests that a 68.4% (95% CI: 67.0- 69.7%) of the infections are caused by infections before the symptoms appear, which is a much stronger pre-symptomatic influence than what was predicted in the literature 44% (95% CI: 25-69%) using serial data from 77 individuals.
The Study for Usefulness of Mandala Art Therapy in Primary Dysmenorrhea
Authors: ST Oh
Published: September 2022

Primary dysmenorrhea is painful menstruation due to uterine functional origin without any other gynecologic diseases such as endometriosis or adenomyosis. The pain of primary dysmenorrhea is from hyper contraction or high sensitivity to pain. The primary dysmenorrhea has been treated by NSAIDs (nonsteroidal anti-inflammatory drugs) or oral contraceptives from the past. However, primary dysmenorrhea is not controlled in all patients by these treatments. Some patients need more supportive treatment. The many supportive treatment have tried to this condition. The art therapy can also tried for this supportive treatment, so we studied mandala art therapy for primary dysmenorrhea. The purpose of this study is observing the usefulness of art therapy for supportive therapy of primary dysmenorrhea.We estimate the degree of pain by VAS (Visual Analog Scale), and statistically compares the change of pain before and after mandala therapy by χ-square with Fisher’s exact test. We did mandala therapy 2 times/week from menstruation to next menstruation, and we compare the change of pain before and after mandala therapy by VAS score. The result of this study is as follows. We observed the pain change in 10 patients. The four of 10 patients felt no change in pain after therapy, but the 2 of 10 patients felt no pain after therapy. The four of 10 patients felt decreased pain after therapy although not disappear completely. Therefore, the six of 10 patients can be felt decreased pain after mandala therapy (P<0.05). The mandala art therapy can be useful for supportive therapy of primary dysmenorrhea. However, a study of the bigger population is needed to confirm this effect for primary dysmenorrhea
Protective Efficacy of Different Live Attenuated Infectious Bronchitis Virus Vaccine Combination against Challenge with GI11 (BR-Type) Strain
Authors: FS Fernando
Published: September 2022

The infectious bronchitis virus (IBV) is an avian coronavirus that causes a highly contagious disease that results in substantial economic losses to the poultry industry worldwide. The prevention is mostly based on biosecurity measures and vaccination. The vaccination programs are defined by epidemiological status and cross-immunity provided against different serotypes. Programs using vaccine combinations can be designed to increase protection. We conducted an experimental study to compare two vaccine programs on protection against a virulent strain belonging to the GI-11 genotype (BR-type) isolated in Brazil using two different Mass-type vaccines combined with a BR-type live vaccine. Two groups of commercial chicks were vaccinated at day-1 using two commercially available Mass-type vaccines + BR-type vaccine. They were challenged intranasally at 28-day using 104 EID50/0.1 microliter/chick of wild-type G11 IBV (IBV/24W). Ciliostasis, macroscopic and microscopic lesion scores were evaluated at 4 and 11-days post vaccination (dpv) and 5 days post infection (dpi) and not showed differences between vaccinated groups. MLV+BR-Type group presented highest amount of BR strain vaccine and lowest amount of Mass strain vaccine in tracheal and cloacal swabs at 4 and 11 dpv. In the other hand, the Ma5+BR-type group showed fewer BR-type positive in both samples tested. After challenge, MLV+BR group showed higher titer of antibody measured by ELISA. These results suggest that the selection of a Mass-type vaccine strain can impact directly in the BR vaccine replication, when used associated, and consequently the induction of humoral immune response. Despite that, both protocols provided protection against the challenge with G11 strain.

Published: September 2022

Kemacetan lalu lintas sering terjadi di simpang karena merupakan tempat bertemunya berbagai pergerakan yang tidak sama arahnya. Perbedaan tersebut dapat menimbulkan kecelakaan lalu lintas, seperti yang terjadi di simpang bersinyal sekitar gerbang utama Universitas Muhammadiyah Surakarta. Simpang ini berada pada pusat tarikan pergerakan karena berdekatan dengan pusat perbelanjaan modern, perkantoran, dealer kendaraan, kampus dan rumah sakit. Adanya halte Batik Solo Trans di sekitar simpang tersebut juga menyebabkan adanya aktivitas bus yang berhenti untuk menaikkan dan menurunkan penumpang. Penelitian ini bertujuan untuk mengevaluasi kondisi simpang bersinyal yang terjadi pada saat peak hour pagi dan siang. Evaluasi yang dilakukan menggunakan metode Manual Kapasitas Jalan Indonesia 1997, dengan parameter utama penilaian kinerja adalah derajat kejenuhan, antrian dan tundaan. Berdasarkan hasil analisis dapat disimpulkan bahwa arus simpang tertinggi adalah 3123,7 smp/jam yang terjadi pukul 13.30-14.30, dengan volume pendekat tertinggi ada di Barat sebesar 1572,9 smp/jam. Kapasitas pada pendekat ini adalah sebesar 879,8 smp/jam, sehingga diperoleh derajat kejenuhan sebesar 1,71. Nilai ini sudah melebihi standar yang ditentukan yaitu sebesar 0,85. Selain Barat, pendekat lain yang tidak memenuhi adalah Utara dan Timur fase 1. Oleh karena itu simpang dianggap sudah tidak layak lagi. Berdasarkan hasil tersebut, maka simpang perlu dilakukan perbaikan, diantaranya melalui pengaturan ulang sinyal (baik fase maupun waktu sinyal), maupun dengan memperbaiki kondisi lingkungan sekitarnya termasuk geometriknya.

Published: September 2022

Steel reinforcement is well known as an important component in forming building structures. However, as the community's need for reinforcing steel is increasing, the main material for forming steel reinforcement is decreasing so that the price is getting higher. The alternative that is suggested as a substitute for tensile steel reinforcement which is economical and easy to get is bamboo. The purpose of this study was to determine the ratio of beam bending using circular and square bamboo reinforcement and to determine the bending load that can be accepted by circular and square bamboo reinforcement. In this study an experimental method was used by conducting a series of tests ranging from preserving bamboo and testing aggregates as a building block for concrete. The cross sections of bamboo reinforcement used are square and circle shapes with a diameter of 10mm with beam dimensions of 900 mm x 150 mm x 150 mm. The results showed that the flexural strength produced by steel reinforcing concrete beam was 11,36 MPa, circular cross section bamboo reinforcing beam 8,73 MPa and rectangle cross section bamboo reinforcing concrete beam of 9,04 MPa.

Authors: Bagenda Dadan Nurdin , Basjaruddin Noor Cholis , Darwati Endang , Rakhman Edi
Published: September 2022

Workers who can control electric motors are currently needed. Therefore, knowledge about controlling electric motors should be taught in vocational high schools. Installation and control of electric motors in the industry are generally used in various devices related to the production process such as controlling the motor driving conveyor belts, controlling pumps on factory pipes, and controlling freight elevators. The problem that arises is the lack of knowledge about electric motor control in vocational school teachers and insufficient facilities for the learning process of electric motor control. Also, Vocational High School (SMK) has not been able to change the old learning patterns to the new learning patterns required in the 2013 curriculum. One of the changes in the curriculum is a change from teacher-centered learning to student-centered learning. In this service program, learning the installation and control of electric motors in the simulator of elevators was developed using the Problem Based Learning (PBL) approach for students of SMKN 1 Cipatat. The first step in implementing this program is to study the curriculum and syllabus applied to the two partner vocational schools, then design a learning process for the installation and control of electric motors using the PBL method. The PBL method was chosen because this method can simultaneously be used to increase students' soft skills such as the ability to innovate, discipline, and the ability to convey ideas both in writing and orally. Besides, the PBL method can also support changes to learning patterns as required in the 2013 curriculum.

Published: September 2022

One of the causes of accidents on trains to date has been caused by damage of railways such as cracked rails, broken rails and other rail defects. Currently, the inspection of the railway line is still carried out manually by the railway inspection officer or Petugas Penilik Jalan Rel (PPJ). However, there is a prototype Autonomous Railways Monitoring Robot (ARMR) which is a prototype inspection robot that can perform rail line checks automatically and be monitored remotely to detect any faults on the railway. The ARMR prototype detects faults as well as locations that are subsequently delivered to users by utilizing some Internet of Things (IoT) features. Faults detected by ARMR prototypes are faults as rail damage. But, the ARMR prototype is unable to distinguish a fault and rail connection. This final task aims to improve armr prototype capabilities to produce information in the form of depth and width of faults, and to distinguish faults and rail connections. The VL6180X sensor is a laser- based distance sensor used as a depth detector for rail faults and rail connections. The Incremental Encoder is enabled to measure the width of the rail fault. The result of ten experiments at 20 cm/s, the ARMR prototype was able to produce 78 mm fault depth size information with an error value of 1,67%, produce 5 mm wide fault width information with an error value of 2,48 % and be able to distinguish faults and connections with 72 % accuracy for the comparison of the distance between the ARMR prototype and the distance shown on google maps.

Numerical prediction of rotary-kiln foundation temperature at an early age
Authors: Tasri Adek
Published: September 2022

The hydration heat confined to the core of the mass concrete during the hydration reaction causes a temperature rise and irregular temperature distribution in the concrete. High temperatures in concrete cause Delay Ettringite Formation (DEF) that cause damage several years after pouring, especially if the concrete is in an acidic environment. The uneven temperature distribution causes thermal stresses that can initiate cracks in the concrete surface. This article discusses a prediction of temperature distribution inside a mass concrete used as a rotary kiln foundation. We measure the heat of hydration of the concrete sample using an adiabatic calorie meter and derive the heat of hydration equation from the measurement data. The hydration heat was used in numerical calculations to obtain the temperature distribution, maximal temperature and temperature differential. The numerical calculation shows that the maximum foundation temperature was 64.01 0C. This temperature is still below the limit temperature for the occurrence of Delayed Ettringite Formation (DEF). The core region has the highest temperature, while the surfaces have the lowest temperature. The difference between the highest and lowest temperatures is 37.40 0C. However, the temperature differential exceeds the safe limit, 20 0C, so heat treatment to prevent cracking needs to be done.

Abstract—Research on clothes waste reduction, especially upcycling suggests that solutions aimed at reducing clothing waste are effective. Based on this ground, further research on upcycling is carried out. As Indonesian millennials can be categorized as ecologically conscious consumers nowadays, it is possible that upcycling can grow more rapidly and become the solution to the world-waste problem. To make that happen, further research needs to be done to increase public and fashion business owners’ awareness. This research examines the willingness to pay for upcycled products in Indonesia. The method of this research is a mixed method - qualitative and quantitative method, which was conducted through online surveys of 30 participants and 5 people in a forum group discussion to gain deeper information. Data were analyzed using van Westendorp’s analysis of price sensitivity. The finding of this research is that the consumers are willing to pay 3-4 times more expensive than the original garment price as the ideal price of upcycled products, the factors influencing it are meaningfulness, familiarity with sustainable products, and quality improvement of the products.

Abstract— Indonesian society is diverse with various segments. One of the segments relevant to the design of fashion products is the division of the social class structure along with the mapping that accompanies each class. The theory that is often used related to social structure is trickle down, where fashion is considered to originate from the upper class society and is then adopted by the middle and lower classes. Trickle down is applied as a theoretical basis in this research based on the dominance of the upper class as consumers of weaving and weaving-based fashion products, especially Tuban gedog weaving in Indonesia. The methods used are interviews, questionnaires, and visual form experiments through the ATUMICS method. The method above produces bag designs that adopts design trends for the upper class, but with some adjustments for the middle class regarding shape, style, color, detail, and decorative elements. The adjustment is intended to answer the needs of middle class consumers in terms of bag design and function, as well as product selling prices. A survey of bag designs at the end of the study shows that the middle class in Indonesia has a different trend from the upper class so that trickle down is not suitable for consumers in Indonesia.

Abstrak— Masyarakat di Indonesia bersifat majemuk dengan beragam segmentasi. Salah satu segmentasi yang relevan dengan desain produk mode adalah adanya pembagian struktur kelas sosial beserta pemetaan yang menyertai masing-masing kelas. Teori yang sering digunakan berkaitan dengan struktur sosial adalah trickle down, dimana mode dianggap berasal dari masyarakat kelas atas kemudian diadopsi oleh kelas menengah dan bawah. Trickle down diterapkan sebagai landasan teori dalam penelitian ini berdasarkan dominasi kelas atas sebagai konsumen tenun dan produk mode berbasis tenun, khususnya tenun gedog Tuban di Indonesia. Metode yang digunakan adalah wawancara, kuesioner, dan eksperimen bentuk visual melalui metode ATUMICS. Metode diatas menghasilkan rancangan tas yang mengadopsi tren desain bagi kelas atas, namun dengan beberapa penyesuaian untuk kelas menengah terkait bentuk, gaya, warna, detil, dan elemen dekoratif. Penyesuaian tersebut dimaksudkan untuk menjawab kebutuhan konsumen kelas menengah dari segi rancangan dan fungsi tas, serta harga jual produk. Survei terhadap rancangan tas pada akhir penelitian menunjukkan bahwa kelas menengah di Indonesia memiliki kecenderungan tren yang berbeda dengan kelas atas sehingga trickle down menjadi kurang sesuai apabila diterapkan untuk konsumen di Indonesia.

Abstract—The Minangkabau tribe is part of West Sumatra. This tribe has a concept of living about human behavior that reflects on nature, humans, and society, as well as humans and their Creator. Similar concepts are also expressed in the decorations found in the traditional building of the Gadang house. Follow-up to the preservation of this culture is very important, so that the noble values ​​that shape the character of the nation can be disseminated. Law No. 5 of 2017 describes the Advancement of Culture which has regulated the idea of ​​protecting, utilizing, and developing culture and the importance of introducing adat as community knowledge. Three of the objects of its promotion are customs, traditional knowledge, and folk games. The qualitative method consists of interviews, observations and documentation which is complemented by a literacy study as an initial stage followed by the process of stylizing the ornaments of the Gadang house. The results of the ornament stylization have the philosophy and values ​​of the Minangkabau community and are applied to the design of traditional house playset products, to introduce culture to the wider community.

NiTi arch wires are commonly used at the initial stage of orthodontic treatment, due to their superelastic and biocompatibility properties. Numerous bending models have been considered to anticipate the mechanical responses of the superelastic NiTi wire in the oral environment. It is known that the magnitude of bending force exerted by the NiTi wire is relatively influenced by the magnitude of friction generated at the wire-support interfaces. These data on the variability of friction magnitude for various bending models, however, are very limited in the literature. This study investigated the magnitude of frictional force generated in different bending models through the numerical method. The frictional force in a three-point and a three-bracket model was quantified from the force difference, measured when the wire was deflected in friction and frictionless conditions. Overall, the frictional force magnitude gradually increased as the wire further pressing the support surface at higher deflection. The highest frictional force was recorded when the bracket support was considered, with values of 2.01 N during loading and 1.61 N during unloading. These loading and unloading frictional forces were significantly reduced to 0.25 N as soon as the point support was considered. The high frictional force generated in the bracket model transformed the constant force-deflection trend of superelastic NiTi wire into a gradient force.

Modern solar-powered pumping systems are already being utilized in various fields and industrial applications especially in agricultural water irrigation systems where pumping water at a remote location is required with fewer electricity accessibility from the grid is not feasible. PV solely depends on solar hours per day and it is not reliable when a location exhibits variable weather conditions, such as in Malaysia, having 12 solar hours daily but maximum 5-6 peak performance hours are as usually achieved due to the cloudy and rainy nature of the weather. In this case, PV-grid is not able to generate power as per daily demand and would create voltage sags, swell, and power outage when it is directly connected with the water pumping system for irrigation. To overcome this problem, a PV-DVR solar water pumping system (PV-DVRWP) is proposed in this paper that can mitigate power quality issues arising from PV-grid side such as voltage sags, voltage swells, and power outage by injecting the required amount of voltage into the line to maintain constant load voltage supply. The DVR controller strategy uses dq-abc frame mechanism to extract fault signals by using Park’s transformation method, PID, and hysteresis band PWM signal generator to drive the inverter of DVR connected with a battery storage system. The proposed methodology of the PV-DVRWP system mitigates power quality issues occurring from the PV-grid side by injecting compensating voltage as well as being able to support water pumping systems in case of power outage for a three-phase system.
Semblanza de Tomás de Mercado. Religioso y economista del siglo XVI
Authors: Gallego Morales Daniel José
Published: September 2022

Con ese trabajo se introduce la figura de Fray Tomás de Mercado, dominico sevillano del siglo XVI. Tomás de Mercado realiza un análisis de su realidad muy pertinente a través de un prisma que combina la tradición religiosa escolástica del juicio moral, con el descubrimiento de América y el consecuente cambio en la concepción del mundo tal y como se conocía hasta entonces. Su obra principal, Summa de tratos y contratos, es una guía moral y económica de los intercambios y contratos que comenzaron a darse como consecuencia de este hecho histórico tan singular. Trata sobre cómo debía ser el comportamiento recto y lícito de los comerciantes y tratantes y las consecuencias económicas y conceptuales que estaba produciendo el Descubrimiento. De esta manera, en su obra se puede observar cómo economía y religión no siempre han estado separadas.
