Development of a Graphic Design Learning Module for the Deaf and Hard-of-Hearing (DHH) Students Based on Technology and Learning Style in Malaysian TVET institutions.
Authors: Et. al. Zainuddin Ibrahim, 
Published: April 2021

Graphic Design is used in many industries and involves both the knowledge and skills in creating artefacts. Many Deaf and hard-of-hearing (DHH) students, especially in the Technical and Vocational Education and Training (TVET) institutions are attracted in pursuing studies in this field, perhaps due to the visual nature of the course. However, learning graphic design is challenging for DHH students due to the technologies and teaching approach applied in these institutions. A module which was designed with experts, was implemented in a selected polytechnic which offered the graphic design course for the deaf and non-deaf students. The module used videos and other resources for the different learning styles, as well as a discussion platform on Padlet, and quizzes. An exploratory implementation study on 15 DHH students who volunteered to use the module was conducted. The students’ interactions were monitored and the results of their pre and post-tests during the implementation of the module was analysed to determine if the module was effective for learning. The findings indicate that students could use the module based on their learning styles and were active interacting on Padlet. The results of the pre and post-tests show a significant increase in scores, indicating the effectiveness of the module. Hence, the module has the potential to improve understanding in graphic design among DHH students. The findings have implications on the design of modules for DHH and special needs students. This is in line with TVET aspiration, which is to provide equal access to quality education for all. Further investigation should be done to determine whether the module could be used for other programs involving special needs students.

A Study on The Minimum Exposure Dose For Image Formation In X-Ray Imaging of Extremity
Authors: Yu Sinyoung 
Published: April 2021

Excellent performance of the digital detector can generate medical images at a lower dose. However, if a certain level of dose exposure of the sensor detector can generate an image to recognize it.
In this study, the exposure conditions of the forearm, femur, and ankle joint tests currently used in clinical trials were tested with lower doses. The resolution pattern was analyzed using the Image J program, and the results were obtained by analyzing the Interactive 3D Surface Plot. In addition, by measuring the surface dose and absorbed dose, the digital detector finds the minimum conditions to make an image, and also checks the effect of dose reduction.
The image of the obtained resolution pattern was analyzed by Plot profile using Image J program. It was confirmed that the gray value width decreased at the same pixel distance as the exposure conditions decreased. Even if the exposure conditions were lowered from step 1 to step 4, which is the standard condition of the forearm test, the resolution showed no difference at 1.4 Lp/mm.
In the Interactive 3D Surface Plot, as the range of the gray scale lowered the exposure condition, the shape of the surface contours gradually became blurred and the contrast of black and white shades decreased. The resolution from step 1 to step 3, which is the standard condition of the femur bone test, was 1.2 Lp/mm, indicating no difference. Even if the exposure conditions were lowered from step 1 to step 4, which is the standard condition for ankle examination, the resolution showed no difference at 1.4 Lp/mm.
It is thought that it is necessary to accumulate a lot of data by further subdividing the stage of exposure conditions according to the thickness in more areas.
Analysis Of Eddy Current Loss Of IPMSM According To The Material Of Permanent Magnet
Authors: Et.al Byeong-Chul Lee 
Published: April 2021

In order to reach the performance of the permanent magnet embedded rotor, the choice of magnet is very important. It must be thermally stabilized, and at this point, discussion of eddy current losses is necessary.To proceed with this study, a permanent magnet embedded synchronous motor used in the compressor currently being designed was selected. To derive the eddy current losses in the neodymium-magnets, current density was calculated through the equation. The eddy current loss was mathematically derived using the magnetic conductivity and residual magnetic flux density. Finally, comparative verification was performed through finite element analysis simulation. In this paper, eddy current losses in a N series magnet are mathematically analyzed and we perform comparative verification through simulation using finite element analysis. The Br value indicating the residual magnetic flux density is the lowest in N30 series and the largestin the N48 series. In the case of using the N30 series, the amount of magnetic flux that can be generated is low, so in order to increase the same output, the electric field must be increased by drawing more current from the stator winding. That is, the torque can be further increased. However, since the magnetic flux density experienced by the permanent magnet also increases, eddy current loss that may occur in the magnet eventually increases. There are also a method of using a split magnet to reduce eddy current losses. Inthe case of a permanent magnet holding a large residual magnetic flux density, the magnets loss is reduced, but there is a disadvantage that the price may be expensive. The losses in the permanent magnet are dissipated as heat. If the eddy current loss increases, the magnet demagnetizes, which in turn leads to a decrease in performance. In the selection of magnets, analysis of losses is essential.

Authors: Nandimath Priya T , S Umashankar 
Published: April 2021

Anaemia is a serious concern for the young children as it affects the cognitive performance, development (cognitive and behavioral), coordination, language development and scholastic achievement. Various interventions have been undertaken during last 50 years such as green revolution, PDS, ICDS, etc. Nutritional deficiencies remain with the same burden and nutritional anemia being one of the major concerns in India. Hence it becomes quite evident hat alternative strategies should be tried to improve the nutritional anemia and reduce the morbidity associated with it, such as use of locally available, traditional food to increase the bioavailability of iron and to improve the nutritional behavior through nutritional education. The present study was proposed with an aim to assess the role of Moringa Olifera powder in improving haemoglobin level among the anaemic children. A case control study was conducted at a village, Chikaballapur district of Karnataka. 312 school children were screened for Haemoglobin level; Out of 312 students 124 school children fulfilled the inclusion criteria. 66 children were recruited to control group and interventional group respectively. The children in the interventional group were administered with 3gms per day (1/2 a tea spoon) of Moringa Olifera powder along with their food for 3 months and regular supplements provided at school. Control group was advised to continue with the regular meal and regular supplements provided at the school. Haemoglobin levels were estimated before and 3 months after the intervention. Out of 58 children in the interventional group 33 (56.9%) were females and 25 (43.1%) were males and out of 66 children in the control group 34 (51.55) were females and 32(48.5%) were males. The mean Haemoglobin level of the children in the interventional group before the intervention was 10.332 which increased to 10.967 after the intervention. Similarly the mean Haemoglobin level of children in the control group before the intervention was 9.950 which remained 9.873 after the intervention. The increase in the mean haemoglobin level in the interventional group was significant with the p value of 0.045. After the intervention the children with moderate anaemia decreased from 38(65.5%) to 23(39.7%) and 13 (22.4%) children turned normal in the experimental group and in the control group the children with moderate anaemia increased from 52(78.8%) to 55(81.8%). There a statistically significant marginal improvement in haemoglobin level in the interventional group after three months.

Published: April 2021

Introduction: Fissure sealants are one of the most proven ways to prevent tooth decay. These materials may remain on the tooth for a long time, and other areas of the tooth may decay. The purpose of this study was to present the best method for surface preparation a fissure sealant material (Icon) and composite restoration
Materials and Methods: In this experimental laboratory study, 40 samples of composite restorative material were prepared in 4 groups of 10 discs of 6 mm in diameter and 2 mm in height. Total etch bonding agent was used in the first, second and third groups without surface preparation, with the use of drills and 37% phosphoric acid, and after drilling, respectively. In the fourth group, self-etch bonding agent was used after drilling. After that, Icon resin material was placed on the surface of the composite in a disc of 4 mm with height of 2mm in diameter and was cured. When the samples were thermocycled and incubated, their bonding strength was evaluated with Instron testing machine. Data were analyzed by one-way variance statistical ANOVA tests, Tukey test (p value < 0.05).
Results: The mean value of bond strength of Icon to resin composite was significantly different among the 4 groups (p value < 0.05). The fourth group presented the greatest bond strength value while the third group had the lowest bond strength.
Conclusion: When repairing fissure sealant, particularly Icon using resin composite, the best results of bond strength are achieved through surface roughening with drills and the application of self-etch bonding agents with a mild pH. Acidic etching agents (37% Phosphoric acid), however, have probably destructive effects on bond strength.

Abstract
Searching for the associations between the gene polymorphism and the reproductive traits is essential in defining the genetic native breed specificity, which distinguishes them from the other breeds. The aim of our study was to determine the associations between mutations in the PRL, PRLR, PTGS2, FUT1 genes and sexual and periparturient activity in native Pulawska gilts. The analysis included 72 animals which gave birth to the first litter. Evaluation of the productive value of gilts accounted for indicators of sexual and periparturient activity as well as reproductive traits. The biological material for molecular analyses was obtained from the hair roots of the gilts. The genotype was verified by PCR RFLP analysis. The primers and PCR conditions were determined on the basis of available literature data. Statistically significant differences (P≤0.05) were found at the PRL locus: gilts of AA genotypes (Ins/Ins) at the PRL locus were characterised by longest farrowing duration compared to gilts of AB genotype (P≤0.05). The analysis of PRLR gene showed that gilts of TT genotype revealed a tendency for later occurrence of estrus signs (first and second estrus) and for the markedly longest farrowings (P≤0.05). With regard to PTGS2 and FUT1 loci, no significant differences were found in the parameters of sexual and periparturient activity of the gilts. However, gilts of FUT1 GG genotype gave birth to and reared the largest first litters (P≤0.05). The results of the studies expand the knowledge about the genetic structure and productivity of Pulawska gilts.
Determinants of forest land use decisions among rural farm households in south-western Nigeria

Published: April 2021

Abstract
The study examined factors determining forest land use decisions among rural farm households in south-western Nigeria. Primary data on socio-economic and community characteristics as well as land use systems were obtained from 300 farm households using a structured questionnaire through a multistage sampling technique. The study revealed that marital status (P < 0.01), gender (P < 0.01), land tenure security (P < 0.01), dominant crop type (P < 0.05), and preference for tree on farm land (P < 0.01) are factors influencing forest land use decision in either agroforestry, pure cultivation or in both practices. Land use choice proportion estimation shows that 63 % are still willing to retain their existing land use practice (pure cultivation). A total of 32 % are willing to shift completely from their existing land use practice while 4 % of the respondents are willing to practice both “agroforestry and pure cultivation” simultaneously. The study therefore suggests the need for a change in forest land use policy, particularly, with a view influence the pattern of use, limitation on type of crop that can be grown, and compliance to sustainable land use practice. This would go a long way in driving forest land use towards agroforestry – a practice identified as a means of ensuring food security while ensuring safe environment.

Authors: Kroča Jiří , Komzák Petr 
Published: April 2021

Abstract
A total of 79 Trichoptera species (43 genera, 16 families) were found in the Javorníky Mts. (Czech Republic), including two Carpathian species, Chaetopteryx polonica Dziedzielewicz, 1889 and Potamophylax carpathicus (Dziedzielewicz, 1912). Two further species, Rhyacophila mocsaryi Klapálek, 1898 and Rhyacophila philopotamoides McLachlan, 1879, have, until recently, only been found in the Carpathian Mts. In addition, eight species that occur infrequently or only locally in the Czech Republic were found, Synagapetus moselyi (Ulmer, 1938), Hydroptila angulata Mosely, 1922, Wormaldia pulla (McLachlan, 1878), Plectrocnemia brevis McLachlan, 1871, Tinodes unicolor (Pictet, 1834), Hydropsyche fulvipes (Curtis, 1834), Beraeamyia hrabei Mayer, 1937 and Ernodes vicinus (McLachlan, 1879). Several of these species are listed in the Red List of threatened invertebrates of the Czech Republic (one as endangered, one vulnerable and seven near threatened).
Bombina variegata (Linnaeus, 1758) in rain pools in the Carpathian Mountains (Slovakia)
Authors: Csanády Alexander , Oboňa Jozef , Duranková Silvia 
Published: April 2021

Abstract
Rain pools (pluviotelmata or puddles) are common, small and non-permanent aquatic ecosystems. Data on the use of rain pools by amphibian taxa in the Carpathian Mountains, especially in Slovakia, are rare. In this study we describe the occurrence of Bombina variegata (Linnaeus, 1758), which may use these small aquatic ecosystems as part of their complex life cycle or where they spend their larval period. The most important hydroperiodic factors affecting the vertebrate fauna were the volume and area of the rain pools, the presence (respectively the absence) of shade, water temperature, biotope structure and the presence of several chemical compounds (NO−
3, GH, KH, pH). This study confirms that micro-habitats, such as rain pools, may play an important role for suitable reproduction sites of B. variegata, as stated by several authors from the different countries and regions of its large distributional range. At the same time, data on the presence or absence of different taxa with important conservation status in the monitored habitat aid in the detection of species.
