Authors: Liu Xiaoyan , Gao Mingjing , Mao Ying , Chen Zongze , Zhang Xinying Y. , Wang Chuanhua
Published: July 2022

Two biodegradable chelating agents polyaspartic acid (PASP), aminotriacetic acid (NTA) and one surfactant tea saponin (TS) were used to strengthen the phytoremediation of pyrene-nickel (Ni) co-contaminant soil with Bidens pilosa L. (B. pilosa). The growth of B. pilosa, the subcellular distribution, the geochemical fractionation and the chemical form of Ni as well as the change of soil microbial community structure were investigated. The dry biomass was greatly promoted with PASP addition. More than 80% of the Ni in roots and leaves was distributed in cell wall and soluble fractions. Ni distributions in cell organelles of B. pilosa leaves in NTA-TS treatment and in cell wall of roots in PASP and PASP-TS treatment were all significantly increased. Exchangeable and carbonate-bound Ni increased with the treatment of B. pilosa. The NaCl-extractable Ni was the predominant form in leaves and roots of B. pilosa in all treatments except for that in the leaves in NTA-TS treatment. The microbial community structure changed with the planting of B. pilosa and the addition of fortifiers. The dominant bacteria genus related to PAHs degradation in PASP-TS treatment was Sphingomonas (19.19%). The phytoremediation of pyrene-Ni co-contaminated. soil by B. pilosa was strengthened by the addition of fortifiers.

Published: July 2022

The tectonic stress field was investigated in and around the aftershock area of the Hokkaido Eastern Iburi earthquake ( M JMA = 6.7) occurred on 6 September 2018. We deployed 26 temporary seismic stations in the aftershock area for approximately 2 months and located 1785 aftershocks precisely. Among these aftershocks 894 focal mechanism solutions were determined using the first motion polarity of P wave from the temporary observation and the permanent seismic networks of Hokkaido University, Japan Meteorological Agency (JMA), and High Sensitivity Seismograph Network Japan (Hi-net). We found that (1) the reverse faulting and the strike-slip faulting are dominant in the aftershock area, (2) the average trend of P- and T-axes are 78° ± 33° and 352° ± 51°, respectively, and (3) the average plunge of P- and T-axes are 25 ° ± 16° and 44° ± 20°, respectively: the P-axis is close to be horizontal and the T-axis is more vertical than the average of the P-axes. We applied a stress inversion method to the focal mechanism solutions to estimate a stress field in the aftershock area. As a result, we found that the reverse fault type stress field is dominant in the aftershock area. An axis of the maximum principal stress ( σ 1 ) has the trend of 72° ± 7° and the dipping eastward of 19° ± 4° and an axis of the intermediate principal stress ( σ 2 ) has the trend of 131° ± 73° and the dipping southward of 10° ± 9°, indicating that both of σ 1 - and σ 2 -axes are close to be horizontal. An axis of the minimum principal stress ( σ 3 ) has the dipping westward of 67° ± 6° that is close to be vertical. The results strongly suggest that the reverse-fault-type stress field is predominant as an average over the aftershock area which is in the western boundary of the Hidaka Collision Zone. The average of the stress ratio R = ( σ 1 - σ 2 ) / ( σ 1 - σ 3 ) is 0.61 ± 0.13 in the whole aftershock area. Although not statistically significant, we suggested that R decreases systematically as the depth is getting deep, which is modeled by a quadratic polynomial of depth.
Multisensor Information Fusion and Optimization Technique for Wildfire Detection and Prevention in WSN Environment
Authors: Reyana A. , Vijayalakshmi P
Published: July 2022

Monitoring natural traits like temperature and humidity are imperative for evaluating climate change. Remote sensing applications in wireless sensor networks face a crucial issue in transmitting the information from sensors in a continuous period to the gateway nodes for processing. Correspondingly, sensor nodes are subject to low memory and processing limitations in concern to wireless sensor networks. Wildfires can be started intentionally or unintentionally. The result, however, is disastrous, causing irreversible damage to the ecosystem. With the advancement of intelligent sensor-based control technologies, data fusion and classification have become an essential component of the environmental monitoring system. To predict the occurrence of fire in forests, a fast and effective intelligent control system using Adaptive Decentralized Kalman Filter is proposed. The Decision tree classification can successfully solve problems on the side of the sink node. Thus the described Decision tree classification determines whether fire detection parameters are in the acceptable range and further utilizes a fuzzy-based optimization to improve the performance of the considered complex fusion environment. The experimental results of the proposed model have a detection rate of 98.3 %, demonstrating that the proposed technique is robust. Thus, providing real-time monitoring of certain environmental variables for continuous situational awareness and instant responsiveness.

Pyrite geochemistry in a porphyry-skarn Cu (Au) system and implications for ore formation and prospecting: Perspective from Xinqiao deposit, Eastern China
Authors: Xiao Xin , Zhou Taofa , Hollings Pete , White Noel C. , Fan Yu , Zhang Lejun , Fu Bin
Published: July 2022

Stratabound ore has been recognized as an end-member of porphyry copper systems, but pyrite chemistry has not been widely applied to linking stratabound ore with the related porphyry and skarn system. Stratabound ore is commonly developed around porphyry-skarn systems in eastern China, and is characterized by abundant colloform pyrite; however the origin of the colloform pyrite has been contentious. Xinqiao deposit is ideal for study of pyrite geology and geochemistry with the aim of elucidating formation of the stratabound ore and to decipher the evolution of pyrite compositions in a porphyry-skarn environment. The colloform pyrite paragenesis and S isotopes indicate that it formed during early skarn mineralization, based on its occurrence in stockwork veins cutting skarn minerals, and that it is replaced by later hypogene sulfides; the δ34S of colloform pyrite (average 6.12‰) is close to the δ34S value of both porphyry-(average 5.06‰) and skarn-type pyrite (average 4.65‰). The colloform texture formed as an aggregate of nanometer- or micrometer-sized (<0.2 µm) pyrite cubes produced by rapid crystallization from a high-fS2, low-temperature, and supersaturated fluid. Super-saturation of the fluid was probably produced by rapid decompression that triggered fluid boiling and cooling when the magmatic-hydrothermal fluid (derived from Cretaceous magma) flowed along the Devonian-Carboniferous unconformity. Subsequently, the colloform pyrite was replaced by later stage pyrite with distinctive trace elements (Co, Ni, and Se), indicating that the stratabound ore at Xinqiao formed from multiple pulses of magmatic-hydrothermal fluids derived from an Early Cretaceous stock.

Co, Ni, and Se enrichment in porphyry- and proximal skarn-type pyrite suggests they formed at relatively high temperature, whereas the colloform pyrite shows trace element contents (Cu, Pb, Zn, Ag, and Bi) similar to those in distal skarn pyrite, suggesting that they may have formed in the same fluid environment. The trace element variations in pyrite from stratabound, skarn and porphyry ore probably resulted from decreasing fluid temperature and increasing pH away from the source. Our data, combined with previous studies, show that Co and Ni in pyrite increase toward porphyry and skarn ore, whereas As, Sb, Pb, Ag, and Bi are enriched in pyrite in distal stratabound ore, which extends for 1–2 km away from the intrusion. A plot of As/Se vs. Co discriminates the three ore types that occur associated with porphyry-skarn Cu systems in the Middle and Lower Yangtze belt (MLYB). These results indicate pyrite chemistry can be effective in discriminating the genesis of different deposit types related to porphyry-skarn systems and can potentially be used as a vectoring tool during exploration in the MLYB and elsewhere.

Published: July 2022

Atherosclerosis continues to be a significant consequence in type I diabetes mellitus (T1DM). Cardiovascular disease, caused by accelerated atherosclerosis, is the leading cause of illness and often premature death in patients with T1DM. Risk management is critical. Patients with T1DM who are at an increased risk include those who are less than 10 years old at the time of diagnosis, have a longer history of diabetes, have microvascular problems, or have several risk factors. It is frequently difficult to evaluate vascular hazard and the degree of atherosclerosis on an individualized level, especially early on.

Published: July 2022

Background: Chronic total coronary occlusion (CTOs) is associated with an increased risk of adverse clinical outcomes. The benefits of percutaneous coronary intervention (PCI) in CTO are still being debated due to the limited data available. This study aims to determine the relationship between the success of PCI in CTOs and the reduction of major cardiovascular events compared to those who failed or did not perform revascularization in patients with chronic coronary total occlusion in RSUD by Dr. Saiful Anwar Malang. Methods:This study is an analytic observational study with a retrospective cohort design. Of a total of 2165 patients who underwent angiography at Saiful Anwar Hospital, Malang, for the period August 2017–September 2020, consecutively, 578 patients with lesions of at least one CTO were found. There were 68 patients who were excluded, so 510 patients were analyzed in this study. They were divided into two groups, the CTO group that was successfully revascularized with PCI (n = 141) and the group that was not revascularized (n = 369). The outcome of this study was major cardiovascular events (MACE), which included cardiac mortality , all cause mortality, and rehospitalization events. Result: Patients with CTO who were not revascularized compared to those with revascularized CTO had a higher history of heart failure, involvement of LM disease, multivessel disease, and three vessel disease (41.2% vs 18.4%, p = 0.041; 16.5% vs 1.8%, p < 0.001; 69.4% vs 22.7%, p < 0.001; 56.5% vs 14.1%, p < 0.001) with a lower mean LVEF (0.49 ± 0.06 vs 0.51 ± 0.07, p=0.045) and older age (60±9 vs 57±8 years ; p=0.007).. At a 12-month follow-up, in the CTO group that was successfully revascularized by PCI, there was a better prognosis than the non-revascularized CTO group in terms of major cardiovascular events (19.9% vs 33.1% Plog-rank = 0.002). These results were consistent for all-cause mortality (5.5% vs 20.6%, Plog-rank =0.027), cardiac mortality (3.7% vs 20.6%, Plog-rank < 0.001) and rehospitalization events. (7.5% vs 32.2%, Plog-rank = 0.001). Conclusion: Successful revascularization of CTO by PCI may provide clinical benefits in patients with CTO in association with major cardiovascular events.

Authors: Iskandar Iskandar , Widasmara Seprian , Pancasari Ratna , Martini Heny
Published: July 2022

Background : ASD closure ASD closure with a transcatheter is the first choice in patients who meet the criteria for insertion. Closure using this method is relatively safe, and has low complications. Several factors must be considered so that this closure action can be optimal. Case illustrations: A 24-year-old woman with complaints of shortness of breath during strenuous activities since 3 years ago. Transthroracal echocardiography showed a gap in the IAS of 1.7-1.9 cm. The patient then underwent TEE and DXRL. The patient was planned for percutaneous ASD closure with zero fluoroscopy. The patient was punctured on the right femoral, and entered into the occluder memopart no 24 mm. Do a wriggle test, the occlude tool is installed properly. When the device was pulled out, the patient's blood pressure dropped to 75/52. On TEE examination, pericardial effusion was found and pericardiocentesis was performed, obtained 600 cc of fluid. The patient was then observed in the ICVCU, and there was no additional free fluid in the pericardial cavity. Discussions: ASD closure can be done through percutaneous and surgery. Closure via percutaneous is the main option. Complications and treatment period is shorter than surgery. Preparation and timing of appropriate action is closely related to clinical outcomes. Observation and knowledge of the risks of the procedure are very important to be able to detect complications and optimize clinical outcomes.

Authors: Rahayu Amy Yayuk Sri , Khafian Nidaan , Rahmayanti Krisna Puji , Anza Fikri Akbar , Afra Syifa Amania
Published: July 2022

The Depok City One-Stop Integrated and Investment Service (DPMPTSP) has an important role in providing public services in Depok City, especially in licensing services. During the last four years, the trend of investment realization in Depok City showed a positive trend in 2017 and 2018. During the pandemic, investment realization decreased due to the Covid-19 pandemic, but public demand for business permits is still quite high. Of the 77 types of licensing services, during the year 2021, 29,491 licenses have been issued. This shows that DPMPTSP has an important role in providing licensing services in Depok City. During the pandemic, the DPMPTSP requires strengthening licensing services related to increasing investment. The objectives of this research are; How is the strategy for strengthening licensing and non-licensing services at the DPMPTSP through an analysis of the organization's internal and external environmental factors. This study uses a post-positivism approach, which deductively uses the operationalization of the SWOT concept to find IFAS (Internal Factor Analysis Strategies) and EFAS (External Factor Analysis Strategies) scores. The analysis results show that DPMPTSP Depok City has the capital of strengths and opportunities with a convincing score. Thus, it is possible to do an expansion. However, on the other hand, it also has weaknesses and threats that are quite severe, so empowerment is needed in the field of excellent service, cooperation/networking, and increasing digitalization capacity. The recommendation given is that the strengthening of the Depok City DPMPTSP must be directed to minimize weaknesses and threats.

UNSTRUCTURED

The COVID-19 pandemic has spotlighted the intertwining of politics and public health. So too, a public health tool, surveillance, can also be used to expose the political context of an event and to guide better public health interventions. In its current form, infoveillance tends to neglect identity and interest-based users. Adopting an algorithmic tool to appropriately classify short social media texts might remedy that gap. Our study advances a computational framework to cluster Twitter users based on their identities and interests as expressed through Twitter bio pages. The framework then uses BERT topic modeling to identify topics by the user clusters. By analyzing the Twitter discourse on masks and mask-wearing during COVID-19 in the English-speaking world, we show how online discourse shifted over time and varied by four user clusters: Conservative political, Progressive political, General Public, and Public Health Professionals. The political groups and general public focused on the science of mask-wearing and the partisan politics of mask policies. A populist discourse that pits citizens against elites and institutions was identified in some tweets. Politicians (such as Donald Trump) and geopolitical tensions (with regards to China) were found to drive the discourse. Our data show limited participation of public health professionals compared to other users. We conclude by discussing the importance of a priori user classification in analyzing online discourse and illustrating the fit of BERT topic modeling in identifying contextualized topics in short social media texts.
Application of Drones in healthcare: A systematic Review (Preprint)
Authors: Okonkwo Emmanuella , Koshechkin Konstantin
Published: July 2022

BACKGROUND

In developing countries, Lack of suitable healthcare infrastructures and proper road systems has posed a serious challenge to the effective operation and delivery of health care products to the individuals that live in remote areas. Drones have also played a significant role in healthcare in several parts of developed countries, especially in search and rescue and natural and humanitarian disasters. The application of drones in the ecological and environment has proved to be very successful. Although there has been a much slower integration of drones in the healthcare field. These challenges can be attributed to ethics surrounding healthcare and Medicine. Medical drones have been used in telemedicine, delivery of medical supplies to remote areas, search and rescue activities and humanitarian purposes.

OBJECTIVE

To identify the different applications of drones in healthcare

METHODS

The study’s search strategy identified relevant literature in the following databases: PUBMED and Google scholar. The PUBMED database was searched for the terms ‘drone’ or ‘unmanned aircraft systems or unmanned aerial vehicle’ OR remotely piloted aircraft systems’ OR remotely
piloted vehicles and Medicine. A separate search was conducted in Google Scholar. The search term was “Use of drone/unmanned aerial vehicle delivery in medicine”.

RESULTS

The initial search using the keywords ‘Drone’ OR ‘unmanned aircraft systems’ OR Unmanned
aerial vehicle’ OR Remotely piloted aircraft systems’ OR Remotely piloted vehicles’ identified
3072 results. When searched together with the keyword Medicine, 250 articles were found. A separate search on google scholar yielded 275 results. The articles from the two databases were evaluated for eligibility on a case-by-case basis. Finally, only 28 full-text articles met the criteria for inclusion. After a comprehensive review of the articles, the different applications of drones in healthcare can be classified into 3 broad sections. The first is for Humanitarian purpose, where drones are used in small scale mapping after natural disasters and also for search and rescue missions. The second application of drone is for logistics. Drones are used for delivery of medical products such as blood and blood related products, organs and drugs. The last application is in telemedicine.

CONCLUSIONS

Everyday, a new advance is made towards the use of drones in healthcare. Though still set back by issues of medical ethics, drones have proven to be useful in several fields of healthcare. A lot of studies have proven drone technology to be a cost effective, fast and efficient way to carry out tasks, especially tasks impossible or extremely dangerous for humans to carry out. There is a huge potential for telemedicine to improve in remote areas using drones.
Bibliometric Analysis of Global Research Trends on Digital Therapeutics in Its First Decade: Evolution, Opportunities and Challenges (Preprint)
Authors: Wang Zhuo , Gong Kai
Published: July 2022

BACKGROUND

Digital therapeutics (DTx) are gradually showing great potential for application in the management of a wide range of health conditions. However, publication on the global trends of DTx using bibliometric analysis are rare.

OBJECTIVE

This study aimed to provide an overview regarding the current status and trends of DTx researches using bibliometrics from 2012 to 2022.

METHODS

Publications related to DTx were retrieved from the core collection of Web of Science databases from its establishment to 06 April 2022. Linear regression was conducted to analyze the overall publication trend. Two scientometric software (CiteSpace 5.8.R3 and VOSviewer 1.6.18) were used to conduct the bibliometric analyses, including the collaboration and co-citation of countries, institutions, journals, references and authors, the citation bursts of keywords and references, and the keyword clustering analysis.

RESULTS

A total of 745 publications in the Web of Science core collection were included, showing a significant increase in the number of publications on DTx from 2012 to 2022 (t=3.29, P=.009), with the USA having the highest number of publications (256), England having the highest centrality (0.38) and citations (H-index=25). The core author group has not yet been formed according to the criteria of Price law. The key institution is University College London, which has the highest number of publications (52) and centrality (0.17). The key journal is the Journal of Medical Internet Research, which has the highest number of publications (70), co-citations (451) and the highest impact factor (2021=7.076). The top 5 co-cited references are all reviews, 4 of which mentioned low level of trust and engagement. Among the keywords, "adolescent" has the highest centrality (0.10), "mental health" has the highest frequency (80), and "machine learning" has the strongest citation bursts (strength 2.6).

CONCLUSIONS

Despite of flourishing interest in the topic of DTx and its great application potential, there are still considerable challenges that need to be addressed, mainly including unbalanced and insufficient development between regions, limited applicability for non-mental illnesses, lack of core researchers and high-quality researches, and lack of person-based approaches. The integration of digital technologies and medicine offers promising opportunities, promoting the development of DTx towards the direction of intelligence.
A Contested Identity: Contemporary Representation of Indonesian Chinese-Muslims on Instagram
Authors: Giovanni Mulyanto Jesslyn
Published: July 2022

The existence of Chinese Muslims in Indonesia is surrounded by a heavily prejudiced belief that Chinese-ness and Islam are considered "unsuitable". Chinese Muslims, particularly 'converts- turned-preachers', are still considered a unique identity. However, the rise of online Islamic piety on Instagram has become one of many ways for Chinese Muslims' to represent themselves and, to some extent, "normalize" their identities. This paper discusses how Chinese-Muslim preachers, namely Felix Siauw and Koko Liem, represent their versions of Chinese-ness and Islam on Instagram, a popular visual-based social media platform in Indonesia. This research uses Multimodal Discourse Analysis (MDA) to observe the preachers' identity narratives and ways to articulate their Chinese-ness and Islam on their respective accounts posts. It is shown that the heterogeneous stances and contesting interpretations on and about Chinese-ness and Islam in the Chinese-Muslim minority group are to some extent represented through the visual appearance and narrative on Instagram of both preachers. From these two figures, the researcher concludes that elements of Islamic religious identity tend to dominate and even fade ethnic Chinese identity in the negotiations between Chinese and Muslim identities. However, their Chinese-ness was strategically used and symbolically commodified to attract the masses. These two preachers become part of the heterogeneous spectrum of Chinese-Muslim representation in Indonesia and the "pavement" for a common image of the combination of the two identities in Indonesia.

Background and objectives

Hyperkalemia after starting renin-angiotensin system inhibitors has been shown to be subsequently associated with a higher risk of cardiovascular and kidney outcomes. However, whether to continue or discontinue the drug after hyperkalemia remains unclear.

Design, setting, participants, & measurements

Data came from the Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation (ADVANCE) trial, which included a run-in period where all participants initiated angiotensin-converting enzyme inhibitor–based therapy (a fixed combination of perindopril and indapamide). The study population was taken as patients with type 2 diabetes with normokalemia (serum potassium of 3.5 to <5.0 mEq/L) at the start of run-in. Potassium was remeasured 3 weeks later when a total of 9694 participants were classified into hyperkalemia (≥5.0 mEq/L), normokalemia, and hypokalemia (<3.5 mEq/L) groups. After run-in, patients were randomized to continuation of the angiotensin-converting enzyme inhibitor–based therapy or placebo; major macrovascular, microvascular, and mortality outcomes were analyzed using Cox regression during the following 4.4 years (median).

Results

During active run-in, 556 (6%) participants experienced hyperkalemia. During follow-up, 1505 participants experienced the primary composite outcome of major macrovascular and microvascular events. Randomized treatment of angiotensin-converting enzyme inhibitor–based therapy significantly decreased the risk of the primary outcome (38.1 versus 42.0 per 1000 person-years; hazard ratio, 0.91; 95% confidence interval, 0.83 to 1.00; P=0.04) compared with placebo. The magnitude of effects did not differ across subgroups defined by short-term changes in serum potassium during run-in (P for heterogeneity =0.66). Similar consistent treatment effects were also observed for all-cause death, cardiovascular death, major coronary events, major cerebrovascular events, and new or worsening nephropathy (P for heterogeneity ≥0.27).

Conclusions

Continuation of angiotensin-converting enzyme inhibitor–based therapy consistently decreased the subsequent risk of clinical outcomes, including cardiovascular and kidney outcomes and death, regardless of short-term changes in serum potassium.

Short- and Long-Term Progression of Kidney Involvement in Systemic Lupus Erythematosus Patients with Low-Grade Proteinuria
Authors: Wang Shudan , Spielman Allan , Ginsberg Mindy , Petri Michelle , Rovin Brad H. , Buyon Jill , Broder Anna
Published: July 2022

Background and objectives

Lupus nephritis remains a common cause of morbidity and mortality in systemic lupus erythematosus (SLE). Current guidelines recommend performing a kidney biopsy at a urine protein-creatinine ratio of ≥0.5 g/g. However, cross-sectional studies reported a high prevalence of active histologic lupus nephritis lesions, and even chronic irreversible scarring, in patients with low-grade proteinuria. This study was initiated to assess disease progression in patients with SLE and low-grade proteinuria to identify risk factors for progression to overt proteinuria suggestive of clinical lupus nephritis.

Design, setting, participants, & measurements

Patients with SLE who had an incident urinary protein-creatinine ratio of ≥0.2 and <0.5 g/g without known lupus nephritis were identified from the Einstein Rheumatic Disease Registry. Patients who developed a random urinary protein-creatinine ratio of ≥0.5 g/g with or without biopsy during the follow-up period were defined as “progressors.” Patients who progressed to a urinary protein-creatinine ratio of ≥0.5 g/g within 2 years of developing a urinary protein-creatinine ratio of ≥0.2 and <0.5 g/g were defined as “fast progressors,” a subgroup expected to benefit most from early biopsies and therapeutic interventions.

Results

Among 151 eligible patients with SLE and low-grade proteinuria at study entry, 76 (50%) progressed to a urinary protein-creatinine ratio of ≥0.5 g/g, of which 44 underwent a clinically indicated biopsy. The median (interquartile range) time from a urinary protein-creatinine ratio of ≥0.2 and <0.5 g/g to progression was 1.2 (0.3–3.0) years. Of the 20 biopsies performed in the first 2 years, 16 specimens showed active, treatable lupus nephritis. Low complement and shorter SLE duration at low-grade proteinuria onset were associated with progression to overt proteinuria across different analyses. Other associated factors included hypertension, diabetes mellitus, younger age, and the presence of hematuria.

Conclusions

In this longitudinal cohort of patients with SLE and low-grade proteinuria at study entry, over half progressed to a urinary protein-creatinine ratio of ≥0.5 g/g in a short time period.

Aα and Lα-spectral properties of spider graphs
Authors: Brondani André Ebling , Macedo França Francisca Andrea , Silva Oliveira Carla
Published: July 2022

Let G be a graph with adjacency matrix A(G) and let D(G) be the diagonal matrix of the degrees of G. For every real α ∈ [0, 1], Nikiforov [21] and Wang et al. [26] defined the matrices Aα(G) and Lα(G), respectively, as Aα(G) = αD(G)+(1−α)A(G) and Lα(G) = αD(G)+(α − 1)A(G). In this paper, we obtain some relationships between the eigenvalues of these matrices for some families of graphs, a part of the Aα and Lα-spectrum of the spider graphs, and we display the Aα and Lα-characteristic polynomials when their set of vertices can be partitioned into subsets that induce regular subgraphs. Moreover, we determine some subfamilies of spider graphs that are cospectral with respect to these matrices.

Published: July 2022

Abstract: Being fashion conscious means having an interest in it, wanting to dress up and hang out in trendy settings. The desire to adopt and follow contemporary fashion in order to maintain one's status in a social network was referred to as "fashion involvement" or "fashion consciousness." The bibliometric analysis of fashion consciousness was examined in this study. For the bibliometric analysis used in this study, R studio software and the Biblioshiny packages were used. Documents by year, country, author, source, document type, and subject area have all been examined in the study. The new fashion consciousness trends have been highlighted in this review. The study's findings offer recommendations for aggressive marketing in emerging markets like India.
Review on Multistoried Building with Flat and Grid Slab
Authors: Nikam Y. K. , Jadhav Dr. H. S.
Published: July 2022

Abstract: An increase the use of tall structures is caused by a constant rise in population. An earthquake is called on by seismic waves that reach the surface of the earth. Different locations experience different shaking intensity during earthquakes, and these locations also experience various degrees of construction damage. In order to build the structure to withstand an earthquake, these lateral forces on the structure must be estimated and specified. Structures should be stiff and strong enough to control displacement at supports and be designed to resist these rapid forces. Even a building's floor design can vary depending on how the structure responds to load. For long span projects, a conventional slab types are not typically used, but grid slab and flat slab are the most appropriate and cost-effective options. However, these two slabs have recently seen significant growth in India; they are often both flat slabs and grid slabs, which makes them comparable. The usage of flat slab buildings for construction is widespread in the modern day because they have several advantages over conventional RC frame structures in terms of architectural freedom, space use, ease of formwork, and speed of construction. For analysis and design IS 1893:2016, IS 456:2000 are used.
Disparities Among Districts in Central Java Province: Cluster Analysis Based on Several Well-Being Indicators

Published: July 2022

This paper aims to group districts in Central Java Provinces based on several well-being indicators published by The National Statistics Agency of Indonesia (BPS) in 2019. The Ward method used hierarchical cluster analysis to group districts and identified disparities among clusters. The results show that districts in Central Java can be divided into 3 clusters: cluster 1 consists of 4 sections with a high level of well-being; cluster 2 consists of 16 districts with a moderate level of well-being; and cluster 3 consists of 15 districts with the low level of well-being. The average variable score for each cluster indicates disparities among groups. The variable score for cluster 1 with the high level of well-being is far above the score for clusters 2 and 3 in economics, education, sanitation, and public health. Only four districts belong to the cluster with a high level of well-being, all of which have administrative status as a city. In contrast, communities with a low level of well-being all have a managerial position as regencies. The results also found that districts in the western part of Central Java tend to have a lower level of well-being than the eastern part of Central Java. Thus, Central Java Province needs to pay more attention to districts in cluster 3 with a low level of well-being, especially in the western part of Central Java in terms of economy, education, sanitation, and public health.
Does Financial Development Affect the Quality of Environment? Evidence From Indonesia
Authors: Permata Sari Yollit , Prasetya Harby
Published: July 2022

This study aims to see the effect of financial development on carbon emissions. Using PCA to convert variables into small uncorrelated variables while maintaining the original data, this study uses five variables representing the financial sector converted into two components. The first component consists of variables Domestic credit to the private sector by banks and Domestic credit to the private sector. At the same time, the second component includes variables Domestic credit provided by the financial sector, Market capitalization of listed domestic companies, and Stock Traded. We can conclude from the estimation results that the first component is the banking-based financial sector while the second is the stock-based financial sector. While the results of the study using multiple linear regression to analyze the effect of the financial development on carbon emissions found that the financial bank-based industry had a negative relationship. In contrast, the stock-based financial sector had a significant positive relationship with affecting carbon emissions. There are many ways that the government can do to make the financial sector contribute to environmental safety, such as offering interest discounts to encourage investment in energy-efficient technologies and asking companies to do CSR in projects that are more environmentally friendly
