Childhood is the most important period in teaching good habits to children for the growth of their mindset. One of the good habits that can be taught is reading books. Reading books from an early age can develop children's imagination so that it has a positive impact on their creative level for the present to the future. In response to this, of course, we need a special forum to facilitate reading activities especially for children. In Kota Banjarbaru itself, there is no special library for children, only a children's service from the Banjarbaru City Regional Library. The purpose of designing this children's library is as a learning support center as well as educational activities and recreational facilities for children with an age limit of 2-13 years through activities that teach skills and insights that are in accordance with the characteristics of the child, which can attract children's reading interest in the city of Banjarbaru. The main thing that is applied in the design of the children's library in the city of Banjarbaru is that the building has the flexibility for its users to easily and quickly adjust. The method used in designing children's libraries in the city of Banjarbaru uses a behavioral architecture approach as a consideration in designing to direct behavior and accommodate it and answer all problems that arise in the design process. Behavioral architecture is an architecture whose application includes behavioral considerations in the design. Because the main actors of the activity are dynamic children, the concept used is spatial flexibility.

Cempaka is a strategic place for drivers to stop and rest because Cempaka has the potential of distinctive local products that attract drivers to stop and rest. But, this is not supported by adequate facilities. Drivers who stop by can only rest for a limited time with limited facilities. However, not a few drivers who force themselves to rest for a long time in food stalls, mosques or minimarkets, resulting in long queues and forcing visitors to park their vehicles on the shoulder of the road because of limited parking space. This is what underlies the planning of the rest area in Cempaka, with the concept of an integrated rest area, which makes this rest area integrated with the development of the existing potential in Cempaka.

Reading is one of the basic skills that must be mastered by everyone. However, the reading rate of people in Indonesia is very low. In fact, literacy conditions in Indonesia are now in crisis, which is also called a literacy emergency. Increasing interest in reading in the younger generation in Indonesia today is really important amidst so many technologies that are very rapidly developing. Therefore, Indonesia is currently so active at making movements to increase interest in reading. The purpose of this Community Library is to increase the reading interest of Indonesian people while providing adequate facilities for reading for the community. The design of Community Library uses architectural programming method. The process of this method is divided into two stages consisting of preparing a program that is an activity of analyzing data that led to architectural problems and designing designs that can solve problems. The digitalization of books can be used as a way to increase the children and adults interest in reading again. However, that still feels lacking, because it requires a more efficient steps that can further influence the interest in reading and attract the attention of the public to e interested in reading. One way to attract the reading interest of public to be interested in reading  is to turn the library into a creative reading place. This is what underlies the thought of the Community Library. Creating a Community Library with the concept of Recreation Space is expected to help change people's view of reading which was boring to be fun.

Published: September 2021

Sekumpul, Martapura is acknowledged as a religious tourism destination by Banjar District’s Department of Tourism. Its number of visitors increase rapidly each year, crowding the streets especially in Martapura and Banjarbaru. Yearly, monthly, and even weekly events attract a lot of pilgrims, which boost the economic sector of the local community. This location, which was popularized by K.H. Abdul Ghani (also known as Guru Sekumpul)  has now been filled with many activities. Unfortunately, the physical condition of Sekumpul can no longer accommodate the locals nor the pilgrims. The problem of traffic jams, discomfort and unsafety of pedestrians, and even the dryness of the area must be given solutions so that existing facilities will not go to waste. To solve these problems, the “walkable place” concept is applied, which uses the “sense of place” method with its 3 aspects (form, image, and activities). The walkable place concept is considered suitable and applicable for Rearrangement of Sekumpul Corridor, Martapura, solving problems of the physical conditions by road widening while still considering the existing conditions, adding amenities, creating positive spaces, optimizing the potential of the religious and commercial sectors, and also strengthening Sekmpul’s sense of place. The identity and character already formed in Sekumpul cannot be ignored and changed, therefore this design conserves while also developing for the good of the users.

Published: September 2021

Today, field sales and service businesses are continuously endeavoring to form their processes and operations more effective. Managing field employees and their tasks (or activities) are often difficult in most organizations. In field sales and service businesses, organizations mostly have problems with communicating work plans to employees since the workforce is spread over different areas having unique geospatial data. They need smart scheduling and planning information systems to make things planned and organized at the work environment and to automate sales and sales force management functions; and also to plan, track, and manage the allocation of labor resources. This study presents a Geographical Information System (GIS) based comprehensive scheduling system, called Scheduler+ for planning, organizing and monitoring the field employees and streamlining operations of field sales and service businesses. The proposed system aims to ensure dynamic and automatic scheduling customer point based tasks, to provide support to employees, to record the data to be obtained during the realization of tasks, and also to enable reporting and tracking of work performance. In this context, this paper presents the general design and analysis issues including the system context, modules, functionalities, some user interface designs and main development considerations.

A Meaning for the Second Power of the Number Pi. Determining the Surface of a Regular Conoid by Virtue of Ramanujan’s Approximation
Authors: Cabeza Lainez Joseph
Published: September 2021

Unlike the volume, the expression for the lateral area of a regular conoid has not yet been obtained by means of direct integration or a differential geometry procedure. As this form is relatively used in engineering, the inability to determine its surface, represents a serious hindrance for several problems which arise in radiative transfer, lighting and construction, to cite just a few. Since this particular shape can be conceived as a set of linearly dwindling ellipses which remain parallel to a circular directrix, a typical problem appears when looking for the length of such ellipses. We conceived a new procedure which, in principle, consists in dividing the surface into infinitesimal elliptic strips to which we have subsequently applied Ramanujan’s second approximation. In this fashion, we can obtain the perimeter of any ellipse pertaining to the said form as a function of the radius of the directrix and the position of the ellipse’s center on the X-axis. Integrating the so-found perimeters of the differential strips for the whole span of the conoid, an unexpected solution emerges through the newly found number psi (ψ). As the strips are slanted in the symmetry axis, their width is not uniform and we need to perform some adjustments in order to complete the problem with sufficient precision. Relevant implications for technology, building science, radiation and structure are derived in the ensuing discussion.
An Investigation of Uniaxial Mechanical Properties of Excised Sheep Heart Muscle Fibre – Fitting of Different Hyperelastic Constitutive Models
Authors: Nemavhola Fulufhelo , Ngwangwa Harry M , Pandelani Thanyani
Published: September 2021

Abstract : This paper presents the investigation of biomechanical behaviour of sheep heart fibre using uniaxial tests in various samples. Non-linear Finite Element models (FEA) that are utilised in understanding mechanisms of different diseases may not be developed without the accurate material properties. This paper presents uniaxial mechanical testing data of the sheep heart fibre. The mechanical uniaxial data of the heart fibre was then used in fitting four constitutive models including the Fung model, Polynomial (Anisotropic), Holzapfel (2005) model, Holzapfel (2000) model and the Four-fibre Family model. Even though the constitutive models for soft tissues including heart myocardium have been presented over several decades, there is still a need for accurate material parameters from reliable hyperelastic constitutive models. Therefore, the aim of this research paper is to select five hyperelastic constitutive models and fit experimental data in the uniaxial experimental data of the sheep heart fibre. A fitting algorithm was made used to optimally fitting and determination of the material parameters based on selected hyperelastic constitutive model. In this study, the evaluation index (EI) was used to measure the performance and capability of each selected anisotropic hyperelatic model. It was observed that the best predictive capability of the mechanical behaviour of sheep heart fibre the Polynomial (anisotropic) model has the EI of 100 and this means that it is the best performance when compared to all the other models.
Visual Short-Term Memory for Coherent and Sequential Motion: A rTMS Investigation
Authors: Pavan Andrea , Ghin Filippo , Campana Gianluca
Published: September 2021

We investigated the role of the human medio-temporal complex (hMT+) in the memory encoding and storage of a sequence of four coherently moving RDKs by applying repetitive transcranial magnetic stimulation (rTMS) during an early or late phase of the retention interval. Moreover, in a second experiment we also tested whether disrupting the functional integrity of hMT+ during the early phase impaired the precision of the encoded motion directions. Overall, results showed that both recognition accuracy and precision were worse in middle serial positions, suggesting the occurrence of primacy and recency effects. We found that rTMS delivered during the early (but not the late) phase of the retention interval was able to impair not only recognition of RDKs, but also the precision of the retained motion direction. However, such impairment occurred only for RDKs presented in middle positions along the presented sequence, where performance was already closer to chance level. Altogether these findings suggest an involvement of hMT+ in the memory encoding of visual motion direction. Given that both position sequence and rTMS modulated not only recognition but also precision of the stored information, these findings are in support of a model of visual short-term memory with a variable resolution of each stored item, consistent with the assigned amount of memory resources, and that such item-specific memory resolution is supported by the functional integrity of area hMT+.
Powers of Elliptic Scator Numbers
Authors: Fernandez-Guasti Manuel
Published: September 2021

Elliptic scator algebra is possible in 1+n dimensions, n∈N. It is isomorphic to complex algebra in 1+1 dimensions, when the real part and any one hypercomplex component are considered. It is endowed with two representations: an additive one, where the scator components are represented as a sum; and a polar representation, where the scator components are represented as products of exponentials. Within the scator framework, De Moivre’s formula is generalized to 1+n dimensions in the so called victoria equation. This novel formula is then used to obtain compact expressions for the integer powers of scator elements. A scator in S1+n can be factored into a product of n scators that are geometrically represented as its projections onto n two dimensional planes. A geometric interpretation of scator multiplication in terms of rotations with respect to the scalar axis is expounded. The powers of scators, when the ratio of their director components is a rational number, lie on closed curves. For 1+2 dimensional scators, twisted curves in a three dimensional space are obtained. Collecting previous results, it is possible to evaluate the exponential of a scator element in 1+2 dimensions.

In 2019, the Ministry of Finance issued a Super Tax Deduction policy, a tax incentive provided by the government to businesses/industries involved in vocational education programs, including research and development activities to generate innovation. This program provides a maximum gross income reduction of up to 200% of the total costs incurred for work practices, apprenticeship, and/or vocational education learning services. This program is designed to encourage establishing a link-and-match between the world of education and industry to improve the quality of human resources produced by the education sector. Two years since its launch, the socialization of this program has not been optimal. Only a handful of industries have taken advantage of this program. Information that does not reach stakeholders causes the program not to run as expected. The tripartite workshop that brings together all stakeholders is expected to be able to share perceptions regarding the nature and technical implementation of the policy.

IMPLEMENTATION REGIONALIZATION PRINCIPLE BASED ON SANITARY AND PHYTOSANITARY (SPS) AGREEMENT ACCORDING TO VIENNA CONVENTION ON THE LAW OF TREATIES (VCLT) OF 1969
Authors: Manalu Velicia Theoartha , Rosadi Sinta Dewi , Amalia Prita
Published: September 2021

The practice of the regionalization principle in Article 6 Sanitary and Phytosanitary (SPS) Agreement is still conflicted. This is because of several cases regarding the members misinterpretation of international guidelines in the regionalization principle, such as India – Agricultural Products and Russia – Pigs (EU). Recently, Coronavirus Diseases 2019 (Covid-19) has been considered to affect animal trade. Such conditions prompt the World Trade Organization (WTO)  to recommend the Members to take SPS Measures to protect their domestic market. However, the trade would be inhibited in case the country-wide ban approach is applied. Therefore, this paper discusses the possible SPS measures under the regionalization principle to promote the trade during the pandemic according to WTO decisions from previous cases in line with the VCLT of 1969. The research result shows that the Covid-19 is an obstacle to international trade and makes humans and animals vulnerable to this virus. Consequently, many animal trades have been banned to prevent its spread. To deal with this condition, Indonesia could apply the regionalization principle in Article 6 SPS Agreement. Moreover, the government should update the quarantine law by pointing out the regionalization principle, unlike the zone system rules only applied to animals susceptible to Food Mouth Disease

Se evalúan las propiedades mecánicas y de durabilidad de hormigones de bajo impacto ambiental con sustituciones de cemento por subproductos industriales (35% cenizas volantes y 15% catalizador de craqueo catalítico) y de áridos gruesos por áridos reciclados (20% y 100%). Los hormigones estudiados se han sometido a ensayos de caracterización mecánica, porosidad, permeabilidad al aire y nivel de penetración del ion cloruro. Los resultados obtenidos muestran que las propiedades mecánicas se ven reducidas con el incremento en las proporciones de árido reciclado y de los residuos utilizados como sustitución en la matriz cementante, mientras que las propiedades de durabilidad se ven únicamente afectadas por el aumento en el porcentaje de áridos reciclados. Todos los hormigones estudiados son aptos para ser utilizados como hormigón estructural.

Published: September 2021

A study was conducted in the Muttom-Mandaikadu coastal region, which is among the profitable coastal sectors in Tamil Nadu, to find the groundwater potential as well as its quality by an integrated geophysical, geospatial, and geochemical approach. The GIS-based weighted overlay analysis was used to merge different thematic layers to create the groundwater potential zone map. The geophysical resistivity survey was performed in the study area at 26 stations by applying a Schlumberger vertical electrical sounding technique. The observed data were interpreted using one-dimensional software AGI Earth Imager. The combined vertical electrical sounding result and remote sensing thematic maps have exposed the potential zone of groundwater in the study area. From the inferred results, it was observed that 20.8% of the area has ample groundwater potential, and 7.7 % of the area has scanty groundwater potential. The saltwater intrusion zone has been predicted by validating aquifer resistivity with Dar-Zarrouck (D-Z) parameter. From the geophysical and geochemical interpreted results, it was found that aquifers in 34.6% of the study area are vulnerable to saline contamination. The 4-D model with integrated groundwater quantity and quality suggests that the study area's Western part falls under excellent to good groundwater potential zone and excellent water quality.
High Plasma Levels of Aβ1-42 Affect Monocytes and Macrophages via Biphasic Effects on Myeloid-Derived Suppressor Cells and Granulocyte-Monocyte Progenitors in Mouse Models of Alzheimer’s Disease

Background: Microglia play a crucial role in the pathogenesis of Alzheimer’s disease (AD). Plasma Aβ1-42 levels significantly increase 15 years before the onset of dominantly inherited AD. The effects of high plasma levels of Aβ1-42 on monocytes and macrophages, the hematogenous counterparts of microglia, remain unclear.Methods: We investigated the effects of plasma Aβ1-42 on peripheral monocytes and macrophages in three animal models, including 7- and 11-month-old female APPswe/PS1dE9 (APP/PS1) transgenic (Tg) mice, wild-type (Wt) parabiotic with Tg (paWt(Wt-Tg)) mice, and Wt mice.Results: We found that high plasma levels of Aβ1-42, in younger (7-month) AD mice significantly decreased the amounts of pro-inflammatory macrophages, myeloid derived suppressor cells (MDSCs), granulocyte-monocyte progenitors (GMP), and the plasma levels of interleukin-6 (IL-6). In older (11-month) AD mice, high plasma levels of Aβ1-42 significantly increased the amounts of pro-inflammatory macrophages, MDSCs, GMPs, the plasma levels of IL-6 and TNF-α, and the brain infiltration of bone marrow-derived macrophages (BMDMs). However, high plasma levels of Aβ1-42 consistently increased the amounts of monocytes and the proliferation of bone marrow cells (BMCs) without affecting the phagocytic function of macrophages on Aβ1-42.Conclusion: The response of mouse AD model suggests that a high plasma level of Aβ1-42 affects monocytes and macrophages via its biphasic effects on MDSCs and GMPs. We suggest that intervening in the effects of plasma Aβ1-42 on monocytes and macrophages might offer a new therapeutic approach to AD.

Background: There is growing interest among low- and middle-income countries to introduce electronic immunization registries (EIRs) that capture individual-level vaccine data. While practical EIR guidance documents are available, the real-world implementation experience varies by country. There is an opportunity to learn from countries that have experience implementing EIRs to inform other countries considering the same. Methods: This qualitative study provides a cross-case comparison of the design, development, and deployment of EIRs in three countries: Vietnam, Tanzania, and Zambia. The countries were selected based on PATH’s role in providing technical support to the governments to introduce and scale their EIRs. Through desk review and thematic analyses, we consider findings related to four implementation factors: time, partnerships, financial costs, and technology and infrastructure.Results: The country cases highlight the multi-year timeline required to implement an EIR at scale. Of the 3 countries, only Vietnam has achieved nationwide scale of the EIR after implementing a series of iterative cycles to pilot and redesign the system over 7 years. In terms of partnerships, all three case countries established interdisciplinary national teams with experience in leadership, technology, and immunization, and incorporated end user perspectives from subnational levels in the EIR design and development. It was important for the national government to play an active role to ensure country ownership and sustainability. Financial investment was necessary for design and development, as well as to maintain the EIR beyond the initial deployment, including all recurring costs for system maintenance, updates, and end user support. Finally, technology and infrastructure were important considerations in the EIR design and choice of equipment in each country, and all 3 countries have a local partner to provide ongoing technical support.Conclusions: Comparing implementation factors across these cases highlights practical experience and recommendations that complement existing EIR guidance documents. The findings and recommendations from this study can inform other countries considering or in the process of implementing an EIR.

Published: September 2021

This paper aims to discuss fixed-time tracking control problem for a nonholonomic wheeled mobile robot based on visual servoing. At first, by making use of the pinhole camera model, the robot system model with uncalibrated camera parameters is given. Then, the tracking error system between the mobile robot and desired trajectory is proposed. Thirdly, on the basis of fixed-time control theory and Lyapunov stability analysis, fixed-time tracking control laws are proposed for the robot, which can make the robot achieve the desired value in a fixed time. Simulation results are given at the end.

Pneumoconiosis is a group of occupational lung diseases caused by inhalation of particles of coal, asbestos, silica, or similar substances, leading to fibrosis and loss of lung function. It is the most serious and common occupational disease in the world with an increased incidence but poor prognosis. To further investigate the regulatory mechanisms of lipidomic profiles in pneumoconiosis, we measured plasma lipidomic profiles between pneumoconiosis patients and health. Compared with healthy people, it showed that circulating levels of phosphatidylethanolamine (PE) and free fatty acids (FFA) significantly increased while phosphatidylcholines (PC) and lysophosphatidylcholines (lyso PC) decreased in patients with pneumoconiosis. Clinical trans-omics analyses demonstrated that phenomes in pneumoconiosis connections with multiple lipids. Our data suggested that trans-omic analysis between clinical phenomes and lipidomes might have the potential to uncover the heterogeneity of lipid metabolism of pneumoconiosis patients and to screen out clinically significant phenome-based lipid panels.
