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. The design is a comfortable, varied, and fun reading space with complete facilities.

Published: September 2021

The development of the city of Banjarbaru accompanied by an increase in population and community activities resulting. An increase in the amount of garbage produced. The ideal waste processing and sorting needs and active role from the community is still not running optimally, if these conditions are left the amount of waste that can actually be processed more go more to a landfill or waste damaging the environment. The design of the waste management training center uses the ecological concept with the uses of recycled material or reuse material derived from waste or second thing. Ecological concepts are applied by interactive methods that include design elements namely the wall, floor, plafond, interior, and the composition of the mass and landscape. That concept and method is a solution to create a design that can communicate the importance of community care for the environment and waste process.

Authors: Hadi Meidina Kartika , Sarbini Gusti Novi 
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.

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

<em>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</em>
Combined Geospatial, Geophysical And Geochemical Studies On Coastal Aquifer At Muttom-Mandaikadu Area, Tamilnadu, India

Published: September 2021

Abstract
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
Authors: Li Chunrong , Liu Kangding , Zhu Jie , Zhu Feiqi 
Published: September 2021

Abstract
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.

Abstract
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

Abstract
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.
Exosomal hsa_circ_0007047 Attenuates Pos-myocardial Infarction Remodeling by Promoting Angiogenesis via miR-1178-3p/PDPK1 Axis

Published: September 2021

Abstract
Emerging studies indicate that exosomes and their inner noncoding RNAs, especially circular RNAs (circRNAs), play key roles in gene regulatory network and cardiovascular repair. However, our understanding of exosomal circRNAs on cardiac remodeling after myocardial infarction (MI) remains limited. In the present study, exosomes were harvested from the serum of patients with and without postinfarction cardiac remodeling. The results showed that the level of hsa_circ_0007047 was significantly downregulated in serum exosome of patients with the adverse cardiac remodeling when compared with those without post-MI remodeling or normal subjects. Loss-of-function approaches in vitro established that exosomal hsa_circ_0007047 robustly promoted angiogenesis and stimulated of cultured human vascular smooth muscle cells proliferation and migration. Accordingly, overexpression of exosomal hsa_circ_0007047 in mice significantly attenuated MI-induced myocardial fibrosis and left ventricular dysfunction, accompanied by a larger functional capillary network at the border zone. Further exploration of the downstream target gene indicated that hsa_circ_0007047 acts as a competing endogenous RNA by directly binding to miR-1178-3p and thereby inducing transcription of its target gene phosphoinositide-dependent kinase-1 (PDPK1), a critical positive regulatory factor of angiogenesis. Together, our results revealed that exosomal hsa_circ_0007047 attenuated detrimental post-MI remodeling via miR-1178-3p/PDPK1 axis, which facilitated revascularization, ultimately improved the cardiac function.
