Authors: Heston Yudha Pracastino , Setiawan Bakti , Swasto Deva Fosterharoldas
Published: January 2023

The world population is experiencing urban life disruption since early 2020 due to the Covid-19 pandemic. In Indonesia, Semarang and Yogyakarta both are the capital cities of respective provinces, undergone the peak of pandemic twice. The first peak occurred between January and February 2021, and the second peak occurred in July 2021. The pandemic that occurred in those two cities altered the dynamics of urban social, political, and cultural dynamics. This paper attempted to discover the phenomenon of urban management in Semarang and Yogyakarta in dealing with the Covid-19 pandemic. In this study, statistical description was used by comparing indicators and investigating their relationship using urban platform approach. The study found four major variables in Semarang and Yogyakarta: the quality of the environment; collaboration and coordination among government, society, and private parties; the presence of infrastructure to deal with Covid-19; and pandemic handling in planning and implementation.

We are very honored to receive the prestigious JDR Award for the Most Cited Paper 2022. The winning paper, “Real-Time Tsunami Prediction System Using DONET,” discusses a system that uses data from the Dense Oceanfloor Network system for Earthquakes and Tsunamis (DONET), which was installed in the rupture areas of the 1944 Tonankai and 1946 Nankai earthquakes in order to instantly generate and visualize tsunami prediction information. The forecast information from this system consists of tsunami arrival time, maximum tsunami height, tsunami inundation area, and inundation depth distribution. The system, which visualizes and distributes forecast information for areas where users need it as a supplement to the tsunami information provided nationwide by the Japan Meteorological Agency, has been introduced in Wakayama Prefecture, Mie Prefecture, Chiba Prefecture, and the city of Owase, as well as by Chubu Electric Power Co., Inc. After DONET was installed in the Tonankai rupture area, we were considering the possibility of using DONET data regionally, and we developed the system as results of discussions with Wakayama Prefecture and Chubu Electric Power Co., Inc. Under the concept that the users themselves would be operating the system, we intended to make the system as simple and easy to understand as possible, and to reduce costs by minimizing the number of hardware units. We also considered making the system flexible and scalable, recognizing that each user has a different way of how to use the tsunami forecast information. We were able to receive this award thanks to the cooperation of the people who were involved in many discussions with us during the process of establishing the concept. We will not become complacent going forward, but will continue to improve our system in ways that reflect the opinions of the users. We would like to thank everyone who has cited this paper with their interests.

We are very honored to receive the JDR Award for the Most Downloaded Article 2022, a new award from the Journal of Disaster Research (JDR).

After the 2011 Great Tohoku Earthquake, it is now said that a magnitude 9-class earthquake could occur in the Nankai Trough, and it is necessary for us to know how strong ground motion (shaking) we will experience during such a great earthquake in order to take countermeasures. In this paper, we developed a new seismic motion prediction model that is applicable to M9-class earthquakes. We did this by adding the strong-motion records of the 2011 Great Tohoku Earthquake to the many records accumulated by various organizations since the 1950s. We would like to express our gratitude to all the organizations that provided us with their valuable records.

Nearly 10 years have passed since the publication of the paper, and the records accumulated during that time have helped us to recognize the usefulness of our proposed model. We understand that our paper is still being downloaded in large numbers today and that our model is now being used not only in research but also in practice.

As natural disasters occur more frequently in Japan and around the world, we hope that JDR will continue to grow and develop as an international source of useful knowledge on natural disasters.
Public Evaluation of the Reconstruction and Regeneration of Fukushima 10 Years After the Earthquake
Authors: Nakamura Tetsuya , Lloyd Steven , Maruyama Atsushi , Masuda Satoru
Published: January 2023

This study examines the results of an online survey of Fukushima residents on their impressions of the reconstruction process ten years after the 2011 Great East Japan Earthquake. It aims to gauge the levels of approval and satisfaction that participants have with support for survivors, housing and community reconstruction, industrial and livelihood regeneration, efforts to decontaminate “difficult to return” zones, measures taken to counter harmful rumors, and the use of the reconstruction budget. The key findings are that many participants found little to be satisfied with after the disaster and that the most critical groups were those who had been directly affected by the disaster and older people. Actions that were seen as successful included provision of public emergency housing, the use of the media in counteracting rumors, the opening of major transport links, and efforts to restore agricultural activities. Going forward, the participants were most concerned about whether support for isolated elderly people would continue and whether long-term medical, emotional, and financial support would continue for survivors.
Rapid Estimation of Direct Economic Losses Caused by Significant Earthquakes: An Evidence-Based Model and its Applications
Authors: Toyoda Toshihisa , Cui Qinglin , Ikeda Masaki , Nakamura Hiromitsu , Fujiwara Hiroyuki
Published: January 2023

This paper presents a rapid or real-time estimation method of the economic value of direct stock damages caused by significant earthquakes in Japan. The result will contribute to both the government and private sectors’ early decision-making, particularly for provisional budget allocation. First, we developed a simple but evidence-based model for estimating stock losses explained by a representative earthquake hazard factor and an exposure factor, i.e., seismic intensity and existing stock of physical assets. The key characteristic of our estimation model is that the dependent variable is prefectural damage amount. Still, the explanatory variables come from municipal sources: we overcome this data availability problem through our estimation process. Second, we carefully checked the model’s specification, estimation, and performance to be soundly applied to a real-time assessment of future earthquake events. We also explain the automated measuring of the prefectural direct loss value and its distribution to every 250 m mesh. Finally, we show two examples of the application of our model; one is the case of the 2018 Northern Osaka Earthquake, and the other is the anticipated Tokyo inland earthquake.

Published: January 2023

Background:

Orthopaedic surgeons are at increased risk for many occupational hazards, both physical and mental. The aim of this study was to evaluate a wide range of work-related injuries among orthopaedic surgeons in the United States.

Methods:

An electronic survey was developed to assess both physical and mental occupational hazards among orthopaedic surgeons. Descriptive statistics were analyzed for all survey items and compared using chi-square and paired t tests, as appropriate.

Results:

The 1,645 responding orthopaedic surgeons (7% response rate) reported a total of 2,702 work-related musculoskeletal injuries, 17.9% of which required surgical treatment. Of the 61 who filed a disability claim, only 66% returned to work and 34% retired early. Additionally, 17.4% of respondents reported having been diagnosed with cancer since starting practice, and 93.8% reported experiencing a finger stick at some point in their career. Over one-half (55.8%) had experienced feelings of psychological distress since beginning practice, and nearly two-thirds (64.4%) reported burnout from work.

Conclusions:

This study captured a spectrum of occupational injuries that pose longitudinal risks to an orthopaedic surgeon’s physical and mental well-being. Our hope is that this analysis of occupational hazards will help to raise awareness among the orthopaedic and medical communities and lead to efforts to reduce these risks.

Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.
The Use of Marijuana for Medical Purposes: Between Normativity and the Principle of Islamic Law perspective
Authors: Arif Achmad , Rachmawati Andini , Kamaluddin Imam , Naifah Nurjihan
Published: January 2023

The limited availability of drugs for rare diseases makes some people use various ways to get treatment. One of them is using marijuana as medicine. In Islam, marijuana is not written directly in the texts, but it can be studied with Islamic legal principles in determining its ruling. Therefore, this paper aims to review the use of marijuana for medical needs from the point of view of the principle of Islamic law “al-ḥukmu yadûru ma’a al-'illah wujûdan wa’ adaman” (the law revolving around the cause for issuing it, whether it is present or absent). This study is library research sourced from the Islamic Jurisprudence references, then analyzed by the inductive method. The research results indicate that marijuana as a treatment is relatively new, and Islamic jurisprudence does not explicitly explain its legal use. Moreover, its use for health services is prohibited in the Narcotics Law. Marijuana in Islam is known to have an intoxicating cause that makes it haram (prohibited). The principle of Islamic law, “al-ḥukmu yadûru ma’a al-'illah wujûdan wa’ adaman” (the law revolving around the cause for issuing it, whether it is present or absent), serves as an excellent guide to know when a law applies and when it is suspended. If there is a cause (‘illah), then there is a law; if there is no cause (‘illah), there is no law. However, the reason (‘illah) with marijuana is a type of common cause (al-'illah al-muta’addiyah) where the branches of law (far’u al-ḥukm) follow the original law. Therefore, the use of medical marijuana is still illegal. Islam allows treatment with forbidden materials (haram) only in emergencies following the terms and conditions of emergency (dharuriyat) in Islam.

 

Keywords: Marijuana, Medical, the principle of Islamic law “al-ḥukmu yadūru ma’a al-'illah wujūdan wa’ adaman” (the law revolving around the cause for issuing it, whether it is present or absent)
Pursuing Legal Harmony: Indonesianization of Islamic Law Concept and Its Impact on National Law
Authors: Karimullah Suud Sarim
Published: January 2023

This study responds to a polemic on Indonesia’s formalization of Islamic law, which is inseparable from the dynamics of political authority and the internal views of Muslims. It seeks to describe, explore, construct, and analyze the  ​​Indonesianization of Islamic law, as proposed by Kamsi, an Islamic law professor at Sunan Kalijaga State Islamic University of Yogyakarta, as one of the efforts to make Islamic law become the national law. The Indonesianization of Islamic law, namely by legislating or codifying Islamic law through the state system so that it is enforceable in Indonesia. This study is conceptual research using a legal philosophy approach to comprehend an Islamic legal thought from a sharia scholar using the content analysis method. The results of this study show that the concept of Indonesianisation of Islamic Law uses a modern knowledge system as the paradigm. This effort seeks to nationally legalize Islamic law through Indonesian legal instruments that can give birth to inclusiveness and tolerance coupled with pluralism with differentiation in unification. Its theoretical implication emphasizes a need for epistemological and axiological adjustments to realize the concept of Indonesianization of Islamic law. The idea should also apply nationally within the framework of Pancasila (the Indonesian state’s ideology) as a democratic country.

Keywords: Kamsi, Indonesianization of Islamic Law, National Law.

Adjustable Cone Meter Adapts Automatically to Wet-Gas Conditions
Authors: Carpenter Chris
Published: January 2023

_

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 207505, “Using an Adjustable Cone Meter To Measure Wet Gas,” by Sakethraman Mahalingam, SPE, Saudi Aramco; Gavin Munro, SPE, GM Flow Measurement; and Muhammad Arsalan, SPE, Saudi Aramco, et al. The paper has not been peer reviewed.

_

A traditional fixed-size Venturi meter has a turndown of approximately 8:1 under dry-gas conditions that may drop to as low as 3:1 under wet-gas flow. When the well conditions change, a replacement of the original Venturi meter with one of a different size is needed. In the complete paper, the authors present the design, development, and testing of an adjustable cone meter that has the ability to adapt itself to flow conditions automatically and provide a turndown of as much as a 54:1 under dry-gas conditions and as much as 20:1 under wet-gas conditions.

Adjustable Cone Meter Design

The adjustable cone meter is a variation on a traditional differential pressure cone meter. A moveable sleeve is placed within the meter, and its position is moved using a rack-and-pinion arrangement. When the flow rate is high (Fig. 1a), the sleeve is downstream of the cone and the meter operates like a normal cone meter. This means that the differential pressure at the cone (P1–P2) is sufficiently high and within the measurable range of the meter. When the flow rate drops below a preset value, however, the differential pressure (P1–P2) drops below the measurable range of the meter. While a conventional cone meter would be unable to measure such flow rates, the adjustable cone meter is able to achieve accurate measurements because the meter detects that the differential pressure is below the measurable range and moves the sleeve automatically so that it covers the cone (Fig. 1b). This reduces the internal diameter of the flowline around the cone and causes the differential pressure to move into the measurable range. The meter then uses the differential pressure to again produce accurate flow measurements. In addition, the meter has a second differential pressure sensor downstream of the cone. This is used to measure the liquid fraction of the wet gas.

Meter Design

Exhaustive finite-element analysis (FEA) was conducted to determine the operating stresses within the meter body and its pressure-containing components during operation. The sliding sleeve can maintain full line pressure and features double-pressure seals at either end, safely containing fluids inside the flowline. The primary risk is the deformation and failure of the sliding sleeve because it is a thin metal structure. However, FEA established the minimum working pressure of at least 1,200 psi for the sleeve, gearbox, and meter body, using industry-standard safety factors.

Cone meter calculations are provided in the complete paper.
Global Inflation Problem and Macroeconomic Fluctuations in Sub-Sahara Africa Empirical Analysis of Inflation Shocks from Key Trading Partners
Authors: Taiwo Shakirudeen Babatunde , Uwilingiye Josine
Published: January 2023

Evolving inflationary pressure from the global economy, especially advanced countries and its new directional impacts on emerging economies have provided new evidence on the validity of international transmission of economic shocks from key trading partners as sources of macroeconomic fluctuations in sub-Sahara African countries. A Global Vector Autoregressive (GVAR) model was estimated for inflationary shocks from US, UK, Euro and China on the performance of macroeconomic variables in 21 SSA countries. These countries are grouped into three country classes – oil-rich, other resources-rich and non-resource based economies. This study confirmed that inflation shocks from these economies are significant in driving the macroeconomic fluctuation (Real Gross Domestic Product (rGDP), inflation, exchange rate and short-term interest rate) in the region. In addition, the spillover effects of these were also assessed while noting the divergences of impacts based on the economic structures of economies in the region. The oil-rich countries were found to be the most affected by inflationary shocks from the U.S, China, and Euro.

In recent years, flooding in densely built-up residential areas has tended to increase because of the increased frequency of heavy rain and climate change. Urban pluvial flooding mitigation is needed by reducing the runoff of sewer systems with green infrastructure solutions. Rain barrels (RBs) and rain gardens (RGs) are considered effective stormwater management methods. This study aimed to verify the effectiveness of RBs and RGs in reducing urban pluvial flooding in densely built-up residential areas. This research takes a case study in Miyahara-Cho, Saitama City. This research involves the analysis of the depth of the outlet, the total runoff of the sewer systems, and the flood condition in the sewer to verify the rainwater runoff control effect of RBs and RGs through simulation using EPA stormwater management model version 5.1 (SWMM-5.1). This study simulates two main types of rainfall events: short duration and long duration. The result of short-duration rainfall showed that the combination of rain barrels and rain gardens is highly effective and can be expected to reduce the impact of excess runoff. In the case of long-duration rainfall, the volume and speed of stormwater runoff of the first peak rainfall are reduced.

BACKGROUND
A large number of observational studies have now shown that a decrease in the estimated glomerular filtration rate (eGFR) is associated with an increased risk of cardiovascular disease. However, there are no uniform conclusions regarding the potential relationship between the estimated glomerular filtration rate and cardiovascular disease. We will explore the causal relationship between estimated glomerular filtration rate and cardiovascular disease for the first time using a two-sample Mendelian randomization analysis.
METHODS
We first identified genetic tools for estimating glomerular filtration rate from a genome-wide association study (GWAS). We performed a two-sample analysis of different cardiovascular outcome events using MR analysis with inverse variance weighting, weighted median, MR- PRESSO, MR- Egger, and leave-one-out methods.
RESULTS
The findings showed weak evidence of a potential causal relationship between reduced estimated glomerular filtration rate and heart failure (HF), with IVW results suggesting critical statistical significance (OR = 1.009,95%CI = 1.003–1.015, p = 0.003). In estimating glomerular filtration rate and coronary artery disease (CAD) (OR = 1.006,95%CI = 0.998–1.013, p = 0.14), estimated glomerular filtration rate and cardiovascular disease (CVD) (OR = 1.003,95%CI = 0.995–1.011, p = 0.45), estimating glomerular filtration rate and stroke (OR = 1.000, 95%CI = 0.9998–1.0001, p = 0.95) and estimated glomerular filtration rate and atrial fibrillation (AF) (OR = 1.004, 95% CI = 0.9952–1.0126, p = 0.38) the results of the IVW trial did not suggest a potential causal relationship between eGFR and cardiovascular outcome events.
CONCLUSION
Multiple large MR analyses we performed found a weak causal association between estimated glomerular filtration rate and the risk of heart failure, but we did not find a significant causal association of estimated glomerular filtration rate for other cardiovascular outcome events (stroke, CVD, atrial fibrillation, coronary artery disease).

As an abiotic stress, adverse germination temperatures cause serious disruptions in physiological and biochemical processes involved in seed germination. Using a factorial experiment, we examined the effects of different seed priming treatments on enzymatic and biochemical performance of rice seeds germination under different temperatures. The results showed that the enzymatic and biochemical activities of all rice genotypes are affected by seed priming agent, especially under low germination temperature. At 15°C, seed priming with ascorbic acid was found the best agent for amylase, α-amylase, soluble sugars, catalase, peroxidase, ascorbate peroxidase, superoxide dismutase respectively with 0.095, 0.047, 29.4, 0.049, 10.9, 1.24 and 2.63 units in NORIN-22 genotype and for protease and soluble proteins with 0.058 and 0.79 units in IRON-70-7053-7 genotype. Among the enzymatic activities, at low germination temperature, the superoxide dismutase and at optimum and high germination temperature, the activity of catalase, peroxidase and Protease were the most important enzymatic activity in occurrence of germination potential in terms of seedling length, vigour index, normal seedling percentage and germination rate. Under priming agents, the highest changes in normal seedling percentage were observed at low and optimum germination temperature by ascorbic acid priming in Hashemi (216.9%) and NORIN-22 (13.2%) genotypes, and at high germination temperature under KCl priming in Hashemi genotype (39.4%).

Biomass has been profiled as a potential source of a portfolio of value-added products and energy vectors with applications in different industrial sectors. The Territory of the Southern Coast of Bahia (TSC) in Brazil has a high potential to provide agricultural and forest biomass to small and medium-scale biorefineries. The Territory of the Southern Coast of Bahia (TSC) in Brazil has a high potential to provide agricultural and forest biomass for these bioindustries. This work aims to quantify the biomass of the main agricultural crops of the TSC over the period of 1999 to 2019. For this purpose, the biomass classification in the Municipal Agricultural Production (PAM) of the Brazilian Institute of Geography and Statistics (IBGE) was used, according to its applications in pharmaceutical industries and other industries using the Classification and Regression Tree (CART) algorithm. Moreover, the identification of the main forest species of the Atlantic Forest that can supply bio-based products was included. Thus, a time series analysis was performed. Biomass classification was performed with the inverted tree using the Gini Index. The results indicate that banana production (1.3 Mt) exceeded, over a period of 20 years, cocoa production (1.1 Mt). This occurs despite the higher occupying area of cocoa (5.8 million hectares) compared with that of bananas. Coffee biomass has been profiled as a raw material to be upgraded in various industries, while bananas are oriented toward supplying inputs for the pharmaceutical industry. Forest species also have the potential to be used in the pharmaceutical industry. In conclusion, small and medium-scale biorefineries can help to increase the use of agricultural and forest biomass as a way of providing inputs for several industries and guaranteeing positive social impacts for the population.

Purpose
Collegial Support Meetings (CSM) have been set up in the Gustave Roussy Cancer hospital for inpatients whose complex care requires a multi-professional approachinvolving participants from various fields. CSMs are composed not only of oncologists but also of health-caregivers, a member of the palliative care team, an intensivist and a psychologist. This study aims to describe the role of a newly implemented CSM in a French Comprehensive Cancer Center.
Methods
Each week, the health-caregivers decide the situations to be examined, depending on the difficulty of a clinical case and/or the occurrence of specific events. The discussion goes on to include the goal of treatment, grading the level of care, ethical and psychosocial issues, and the patient's life plan. The patient’s wishes are carefully considered. Finally, to obtain feedback from the teams, a survey has been distributed to the health-caregivers to assess the interest in the CSM.
Results
In 2020, 114 inpatients were involved: 84 patients were metastatic and had received a median of 2 lines of treatment. Their general condition was deteriorated: 50% of patients were entirely dependent on care. During the CSMs, 55% of the discussions focused on whether to continue specific cancer treatment - 29% were about whether to continue invasive medical care - 50% about optimizing supportive care. Forty patients (35%) died during the hospitalization.
Conclusions
CSM, an innovative approach in French oncology, places health-caregivers at the heart of the system and strives to reach consensual and consistent conclusions for all medical and nursing staff involved.

Radiochromic film is a good dosimeter choice for patient QA for complex treatment techniques because of its near tissue equivalency, very high spatial resolution and established method of use. Epson scanners are widely used for film dosimetry. Previous studies reported that different components in the construction of flatbed scanners introduce light polarisation which is responsible for enhancing the Lateral Response Artefact (LRA) effect. The purpose of this study is to investigate the contribution of the scanner bed and mirror system of EPSON flatbed scanners to this effect. EBT3 films were irradiated with 40x40cm2 field size in 6 MV beams. Films were analysed using images captured by a Canon 7D camera utilising a 50mm focal length lens to evaluate the polarization introduced by various combinations of mirrors making up the mirror system. An EPSON V700 scanner is used to investigate the effect of the scanner bed. The magnitude of polarization introduced by the mirror system is found to be up to 14%, whereas the path length effect, from the difference in refractive index of film and scanner bed, is found to be insignificant (at less than 2%).
