Accelerating Full Scale Fatigue Testing
Authors:   Dayton T. Brown Inc., Bradshaw William , Vaddadi Dr.
Published: June 2023

This paper will discuss the use of Model Predictive Control (MPC) to increase the speed and accuracy of airframe fatigue testing. This will save time and cost while providing a very high fidelity test that will greatly reduce future fleet problems. Additionally accelerating fatigue testing allows for more realistic test load spectrum to be utilized, with reduced amounts of spectrum truncation and artificial load increases. A new load control system under development by Dayton T Brown, Inc. (DTB) utilizes Model Predictive Control (MPC) rather than Proportional Integral Derivative (PID) load control to compute test actuator loads. MPC utilizes a model of the test system, a Digital Twin, to determine the best path forward to reduce loading errors and increase test load application rate.

Authors:   Technical University of Munich, John Jonas , Gaugelhofer Lukas , Hajek Manfred , Yavrucuk Ilkay
Published: June 2023

Helicopter and VTOL structures are heavily influenced by vibrations and complex interaction effects. One possible solution to minimize design risks and to enhance cabin comfort is to increase the damping in the vehicle's structure, for which natural flax fibers offer a promising approach. The presented study investigated the hybridization of conventional composites with flax fibers of sub-structural components, including double-T beams and airfoil structures. The frequency dependent dynamic properties of the structures, damping and stiffness, are measured using experimental modal analysis. Local flax rib reinforcements on shells showed a significant increase in stiffness-damping factor but did not improve damping in flax laminates. According to the investigation, hybridization of conventional composites can lead to a significant increase in damping for both, double-T beams and airfoils. The damping can be increased by three to four times, and there can be a significant improvement in the damping-to-stiffness factor.
Bolt Hole Corrosion and Fatigue Damage Repair in Hybrid Vertical Lift Structure
Authors:   PartWorks, Restis Jude , Kokaly Matthew , Dubberly Michael , Manning Dale
Published: June 2023

Cold expansion has been successfully used in aerospace structures, including vertical lift airframes to repair and prevent fatigue damage for more than 50 years. In 2022 PartWorks described an innovative program that would be performed for the United States Air Force using a new process, that included cold expansion, to repair corroded fastener holes (U.S. Patent 11,255,371). This paper will focus on the test results of that development and demonstration program for the United States Air Force (Air Force Research Lab/AFRL) for repairs to bolt holes on aerospace structures with metal/carbon-fiber composite skins. Locations in aerospace structures that combine composites and metallic for vertical lift or fixed wing have demonstrated greater levels of corrosion when compared to all-metal structural skin due to galvanic corrosion between metal and carbon fiber composites. Existing repair methods for these metal/carbon fiber composite skin bolt hole/fastener sites often involve extensive removal of corrosion, non-standard or oversized holes, and extensive modeling/validation to prove repair effectiveness. Existing repairs can also lead to premature structural component replacement. This project evaluated a new repair method that uses cold expansion with thin wall bushings and/or a rivetless nut plate (RNP) to restore fatigue life to the metal bolt hole if damage is missed or potentially without having to remove all the damage/corrosion.
Microstructurally Tailored Materials Improving Structural Performance
Authors:   University of Texas at Arlington, Ghaffari Sarvenaz , Seon Guillaume , Makeev Andrew
Published: June 2023

High-modulus (HM) carbon fiber-reinforced polymers (CFRPs) have attracted strong demand by the rotorcraft industry as such materials can potentially enable lightweight airframes and rotor components with significant weight savings. However, low fiber-direction compressive strength, compared to intermediate-modulus (IM) CFRPs currently used in primary structures, has been a well-recognized weakness of HM CFRPs, prohibiting their implementation in rotorcraft platforms. Microstructural tailoring provides an innovative means for breaking through the fiber-direction compressive strength barrier of the HM CFRPs. Microbuckling, the fiber-direction compressive failure mechanism of the subject HM and IM CFRPs, is driven by fiber-matrix interface shear strength. Assessment of the interface properties using in-situ SEM-based experiments reveal substantial difference in surface topology between IM and HM fibers, which is related to higher interface strength in HM fibers. This instigates a microstructural tailoring approach of reinforcing material surrounding HM fibers with IM fibers to improve microstructural stability. A manufacturing system has been developed, and promising results enabling HM CFRPs with adequate fiber-direction compressive strength have been achieved through hybridization of IM and HM fibers at the filament level in HM CFRP toughened with nano-silica. A new material achieving compressive strength of IM CFRPs but with >30% higher modulus has been developed.

Authors:   Rensselaer Polytechnic Institute, Kim Jae ,   University of Michigan, Shrestha Elena ,   DEVCOM Army Research Laboratory, Reddinger Jean-Paul , McIntosh Kristoff , Mishra Sandipan
Published: June 2023

This paper presents a reinforcement learning (RL) based trajectory planning and control architecture for autonomous landing maneuvers of a quadrotor biplane tailsitter (QRBP). The RL controller replaces a gradient-descent based optimal trajectory planner and outer loop position controller of a standard QRBP control system, while retaining the inner loop for regulating attitude dynamics. The RL agents are trained in a simulated environment, using a curriculum learning approach for training an RL agent capable of landing on a moving Unmanned Ground Vehicle (UGV) with changing velocity. The RL architecture is capable of generating landing trajectories onto a moving ground vehicle, with computational costs suitable for real-time implementation. Further, the RL guidance architecture successfully completes the landing mission more consistently compared to a gradient-descent based guidance architecture when there is uncertainty in the path of the UGV.
System Simulation at Airbus Helicopters: From Early Validation to Formal Certification
Authors:   Airbus Helicopters, Brisset Nicolas , Duffy Andrew
Published: June 2023

Over the last 15 years, Airbus Helicopters has been investing significantly into avionics simulation, in order to leverage its potential all the way from early design validation to integration, testing, verification and recently even certification. One key feature in making simulation a backbone of development activities is digital continuity and the aggregation of the work produced by a large community all along the product lifecycle, with the right sequencing: typically investing early in simulation rather than waiting late until the final development steps to produce a training simulation that will not benefit development. This paper explores the various benefits brought by the approach, putting it into perspective with recent MBSE developments. It also explains recent efforts Airbus Helicopters has been undertaking towards using avionics simulation as a formal Means of Compliance for certification activities, and it underlines some key challenges avionics simulation must address in order to remain relevant in the next years.

Optimized progression of Full-Body In-Bed Gym workout: an educational case report
Authors: Ravara Barbara , Giuriati Walter , Maccarone Maria Chiara , Kern Helmut , Masiero Stefano , Carraro Ugo
Published: June 2023

People suffering from fatigue syndromes spend less time exercising each day, thus aggravating their motor difficulties. Indeed, muscles and mobility deteriorate with age, while exercising muscles is the only sure countermeasure. It is useful to offer a safe and toll-free rehabilitation training: Full-Body In-Bed Gym, easy to learn and performe at home. We suggest a 10–20 min daily routine of easy and safe physical exercises that may improve the main 200 skeletal muscles used for every-day activities. Many of the exercises can be performed in bed (Full-Body In-Bed Gym), so hospital patients can learn this light workout before leaving the hospital. The routine consists of series of repetitions of 15 bodyweight exercises to be performed one after the other without time breaks in between. Alternating sequences of arm and leg exercises are followed by moving body parts in lying and sitting positions in bed. These are followed by series of tiptoeing off the bed. Progressive improvements can be tested by a series of push-ups on the floor. Starting from 3-5, number of repetitions are increased by adding 3 more every week. To maintain or even shorten total daily time of workout each movement is weekly speeded up. The devoted time every morning (or at least five days a week) to train all the major muscles of the body can remain under 10 minutes. Because there are no breaks during and between sets, the final push-ups become very challenging: at the end of the daily workout heart rate, depth and number of ventilations and frontal perspiration increase for a few minutes. We here provide an example of how to implement the progression of the Full-Body In-Bed Gym presenting an educational Case Report of a trained 80-year old person in stable pharmacological managements. In addition to strengthening the main muscles, including the ventilatory muscles, Although performed in bed, Full-Body In-Bed Gym is a resistance training equivalent to a short jog.. Started in early winter and continued regularly throughout spring and summer, Full-Body In-Bed Gym can help maintain independence of frail people, including those younger persons suffering with the fatigue syndrome related to the viral infection of the recent COVID-19 pandemic.

Authors: Ishisaka Mariko , Hanamoto Akiko , Kaneko Makoto , Kato Daisuke , Motomura Kazuhisa , Kataoka Yuki
Published: June 2023

Background: There is a shortage of general practitioners in Japan. With the revision of educational guidelines, general practice (GP) education has improved. However, the amount of education on GP in medical schools remains inconsistent. This study examined the relationship between medical students’ amount of GP-related education and their subsequent choice of GP majors.Methods: A retrospective cohort study was conducted in a teaching hospital in Japan. Participants were residents in the hospital. The exposure comprised compulsory lectures and training time for community-based medicine in medical schools. The outcome included participants choosing GP majors after their initial 2-year junior residency.Results: Fifty-one participants were included in the final analysis. Of these, 14 majored in GP and 37 in non-GP after their initial 2-year junior residency. Of the participants who took GP lectures for 18 hours or more, 11 chose GP majors, and 18 chose non-GP majors (risk ratio, 2.78; 95% confidence interval [CI], 0.88–8.79). Of the participants who underwent training for 12 days or more, 10 chose GP majors, and 16 chose non-GP majors (risk ratio, 2.40; 95% CI, 0.87–6.68).Conclusion: The results do not support the association between the amount of compulsory undergraduate education for community-based medicine and the subsequent increase in the number of residents choosing GP majors in Japan. Educators would do well to explore different approaches, such as improving the quality of education to increase the number of GP residents. Further research is needed to reach more definitive conclusions.

Published: June 2023

Objective

Sport-related concussion (SRC) is an evolving public health concern among youth athletes. Despite emerging evidence that race and ethnicity are important factors in determining concussion outcomes, studies examining race and ethnicity are limited. We conducted a systematic review to (1) determine the prevalence of SRC studies in which participants’ race or ethnicity is reported, (2) describe how race and ethnicity are used within each study, and (3) assess predictive factors for the reporting of race and ethnicity.

Data Sources

PubMed, Embase, PsycINFO, and CINAHL databases.

Study Selection

Study inclusion criteria were (1) primary and peer-reviewed research; (2) related to the diagnosis, treatment, or recovery of SRC; (3) involving school-aged athletes (ages 5 to 25); and (4) with 25 or more participants. The search was performed in March 2021 and included only studies published after March 2013.

Data Extraction

For each article, we looked at whether race and ethnicity were reported, and if so, which races or ethnicities were mentioned. For each race or ethnicity mentioned, we extracted the corresponding sample size and how they were used as variables in the study.

Data Synthesis

Of 4583 studies screened, 854 articles met inclusion criteria. Of the included articles, 132 (15.5%) reported race, and 65 (7.6%) reported ethnicity, whereas 721 (84.4%) reported neither. When examining the demographic characteristics of the 132 studies that reported race, 69.8% of athletes were White. Additionally, 79.5% of these studies used race solely as a demographic descriptor as opposed to a main exposure or covariate of interest. Studies published more recently were more likely to report race. Further, studies in specific study or journal topics and specific geographic locations of the authors were more likely to report race.

Conclusions

Reporting of race and ethnicity is limited in current SRC literature. Future authors should improve the reporting of race and ethnicity, diversify study samples by focusing on enrolling athletes from underrepresented groups, and consider the potential effect of race and ethnicity as social determinants of health on risk factors, recovery, and long-term sequelae after SRC.
Rating of Perceived Exertion Associated With Acute Symptoms in Athletes With Recent SARS-CoV-2 Infection: Athletes With Acute Respiratory InfEction (AWARE) VI Study
Authors: Kaulback Kelly , Schwellnus Martin , Sewry Nicola , Jordaan Esme , Wood Paola
Published: June 2023

Context

SARS-CoV-2 infection can affect the exercise response in athletes. Factors associated with the exercise response have not been reported.

Objective

To (1) describe heart rate (HR), systolic blood pressure (SBP), and rating of perceived exertion (RPE) responses to exercise in athletes with a recent SARS-CoV-2 infection and (2) identify factors affecting exercise responses.

Design

Cross-sectional, experimental study.

Patients or Other Participants

Male and female athletes (age = 24.2 ± 6.3 years) with a recent (<28 days) SARS-CoV-2 infection (n = 72).

Setting

A COVID-19 Recovery Clinic for athletes.

Main Outcome Measure(s)

Heart rate, SBP, and RPE were measured during submaximal exercise (modified Bruce protocol) at 10 to 28 days after SARS-CoV-2 symptom onset. Selected factors (demographics, sport, comorbidities, preinfection training variables, and symptoms during the acute phase of the infection) affecting the exercise response were analyzed using random coefficient (linear mixed) models.

Results

Heart rate, SBP, and RPE increased progressively from rest to stage 5 of the exercise test (P = .0001). At stage 5 (10.1 metabolic equivalents), a higher HR and a higher SBP during exercise were associated with younger age (P = .0007) and increased body mass index (BMI; P = .009), respectively. Higher RPE during exercise was significantly associated with a greater number of whole-body (P = .006) and total number (P = .004) of symptoms during the acute phase of infection.

Conclusions

A greater number of symptoms during the acute infection was associated with a higher RPE during exercise in athletes at 10 to 28 days after SARS-CoV-2 infection. We recommend measuring RPE during the first exercise challenge after infection, as this may indicate disease severity and be valuable for tracking progress, recovery, and return to sport.
Prediction of surgical decision and postoperative renal function using RENAL nephrometry score for localized renal masses: A prospective study
Authors: Abdel Aal Ashraf M. , Nouh Islam , Azeem Mohamed Abdel , Al Adl Ahmed M. , Elmohamady Basheer N.
Published: June 2023

Purpose:

The purpose of the study is to assess the value of RENAL nephrometry score (RNS) in predicting surgical decisions, complications, and decreases in kidney function in patients with localized renal tumors.

Methods:

Cases with solitary, solid, and enhancing renal masses were included, scheduled for nephron-sparing surgery (NSS), and assessed using routine laboratory and radiological data necessary for calculating the RENAL score. The primary endpoint was conversion to radical nephrectomy (RN), while the secondary endpoint was the prediction of a drop in renal function assessed by postoperative estimated glomerular filtration rate (eGFR) at the last follow-up visit compared with the preoperative values. The association between the scoring system and perioperative outcomes was evaluated.

Results:

In all, 84 cases were included, NSS was accomplished in 67 cases while conversion to RN was mandatory in 17 patients, median (interquartile range) RENAL score was 6.2 (4–10) for NSS and 9.7 (6–12) for RN (P < 0.001). Higher grades of complications were observed in the high-complexity subgroup. eGFR was 79.8 that dropped to 75.6 ml/min/1.73 m2 in the late value in patients who underwent NSS, while it was 82.9 that dropped to 58.3 ml/min/1.73 m2 in the late value in patients who converted into RN (P < 0.001). The percentage of drop in eGFR was significantly higher in the moderate and high-risk groups, which was positively correlated with the warm ischemia time. Regression analysis revealed that the continuous RENAL score was a more significant predictor of conversion to RN than tumor size alone. In the 67 NNS cases, the percentage decrease in eGFR was predicted using the continuous RENAL score.

Conclusion:

The RNS is a significant predictor of conversion to RN and can predict the percentage decrease in eGFR after NSS. Further investigations and follow-ups are necessary.

Published: June 2023

Financial performance has a vital role in the company; good financial performance can positively impact the company. This study examines and demonstrates the influence of Islamic corporate social responsibility (ICSR), leverage, and liquidity on financial performance, which is moderated by firm size. The research population is a company registered in the Jakarta Islamic Index 30 (JII 30) for 2017-2021. The sample of this research is ten companies obtained from the purposive sampling method. The data analysis technique uses Moderated Regression Analysis (MRA). Financial performance is measured using return on assets (ROA), leverage using the debt to equity ratio (DER), liquidity is proxied by the current ratio (CR), and ICSR is measured using several predetermined indicators. The results showed that ICSR has no impact on financial performance, leverage has a significant positive impact on financial performance, and liquidity has a significant negative impact on financial performance. Company size cannot moderate the impact of ICSR on financial performance, but company size can moderate the impact of leverage and liquidity on financial performance. This research can complement existing theories and research results. It can be a reference for companies in improving and enhancing their performance, as well as for investors to evaluate company performance to obtain certainty in investment.

PAOO Technique for The Bimaxillary Protrusion: A Case Report
Authors: Das Abhaya C
Published: June 2023

Background: Bimaxillary protrusion is a common malocclusion that can lead to functional and aesthetic issues. Conventional orthodontic treatment may not always be effective, and surgical approaches can be invasive. The Periodontally Accelerated Osteogenic Orthodontics (PAOO) technique is a minimally invasive alternative that involves corticotomy and orthodontic treatment.

Objective: This case report aimed to evaluate the effectiveness of the PAOO technique for the correction of bimaxillary protrusion in a 16-year-old female patient.

Methods: The PAOO technique involved corticotomy and piezocision on a 16-year-old female patient undergoing orthodontic treatment with a fixed appliance. The patient was being followed up for 18 months after orthodontic appliance placement with premolars extractions but did not get any favorable result and was referred by the Department of Orthodontics to undergo corticotomy procedure. The effectiveness of the treatment was evaluated using cephalometric and occlusal analyses.

Results: The PAOO technique significantly improved the patient’s skeletal and dental parameters. The maxillary and mandibular incisors were retracted, resulting in a significant improvement in the patient’s profile. The occlusal analysis showed good intercuspation and a stable occlusion.

Conclusion: The PAOO technique is a viable option for the correction of bimaxillary protrusion, as it can achieve significant improvements in skeletal and dental parameters with minimal invasiveness. Further studies are needed to validate these findings and compare the PAOO technique with conventional surgical and orthodontic approaches.
The asylum case: an analysis of the International Court of Justice's leading judgment on political asylum and regional custom
Authors: Valadares Fernandes Barbosa Lutiana
Published: June 2023

This paper offers an overview of the political background in Peru when a dispute on the political asylum of Victor Raúl Haya de la Torre between Colombia and Peru arose. The claim and counter-claim submitted to the International Court of Justice (ICJ) and the Court´s decision are discussed. It critically reviews the judgment's main issues to the international legal debate: the right of qualification of a political offense, the discussion over regional customary international law, the duty or not to give a safe-conduct, and what should be considered urgency for the purposes of diplomatic asylum. It claims that the unilateral qualification of the offense is essential to the character of diplomatic asylum. It highlights that this was the first decision of an international tribunal that confirms the existence of a regional custom and discusses what is necessary for a local practice to be considered regional custom. It refutes ICJ´s ruling and argues that nowadays, in the Latin-American context, the territorial State is bound to issue a safe-conduct, regardless if it requested the refugee to leave the country. It disagrees with ICJ´s restrictive interpretation of the term “urgent cases” and understands that urgency shall be construed to allow diplomatic asylum in times of political instability and prevent it in times of democratic normality.

Concrete is a brittle material with very low tensile unit deformation capacity and tensile strength. Where these properties of concrete are required, by the addition of high-tech fibers produced from different materials within the concrete, weak properties of concrete are being tried to be improved. In this study, it is aimed to investigate the physical and mechanical properties of concretes obtained by using different fibers at %1, 2 and 3 ratios by keeping amount of cement constant in the concrete mixtures. According to experimental results, it was seen that the increasing fiber additive in the concrete mixtures, flexural strength were increased by addition of fibers to concrete, slump and compressive strength were decreased. In addition, unit weights decreased and thermal insulation properties increased positively.

The season of the year (ES), maximum temperature (Tmax) and relative humidity (RH) affect gestation success of Tropical Milking criollo (TM) heifers, but their effects on the gestation of TM cows are not completely known. The study aimed to determine the effects of environmental factors along with artificial insemination (AI) service and calving on the gestation success of TM cows. Data were collected during 14 years, 959 records of AI of 155 cows in three seasons: hot-dry (HD), hot-humid (HH) and fresh-dry (FD). The response variables were gestation success of cows at first service after first calving (GF), first calving first to fifth service (GS) and global gestation success (GG). Model effects were ES, Tmax and RH seven days before the AI (PRAI), the day of the service (DAI) and seven days after (POAI); and days open (DO), cumulative milk production (MP), number of service (NS) and calving number (CN). GF was analyzed with logistic regression, and GS and GG with generalized linear models. Over 50 % of estrus occurred in the HH season. Tmax affected GF b1 = -0.13 ± 0.07 (p ≤ 0.05) and GG b1 = -0.08 ± 0.04 (p ≤ 0.05) in PRAI. There were no effects of ES, RH, NS or MP on GF, GS and GG for PRAI, DAI and POAI (p > 0.05). DO affected GG in PRAI, DAI and POAI b2 = -0.005 ± 0.002 (p ≤ 0.01). GG were as close to 52.0 % for the three seasons. Although with no statistical differences in multiparous cows (p > 0.05), for NS maximum gestation were 60 % at first and third, and minimum 40 % at fourth services; for CN they were 60 % at fourth, and 40 % at sixth and seventh calving, respectively. TM cows are adapted to a hot tropical Climate and their seasonal changes, showing similar pregnancy frequencies among seasons.

Bank Capital Power (not the actual name), experienced a decrease in CASA in 2021 due to the CASA was leaked to other banks for investment purpose. The management of BCP implemented Investment Training Project in Bandung Branch to train marketers in order to enhance the marketers’ capabilities. The purpose of the study is to evaluate the implementation of the project and advise Bank Capital Power on the project continuation. The data is a primary data collected from Bank Capital Power period October 2021 until December 2022. This study employed three methods to evaluate the Project namely CBA (Cost-Benefit Analysis) and Difference Tests of Profit Generated using Kruskal-Wallis and Mann-Whitney U Test to see if the training profit result is statistically different. Result for the Cost-Benefit Ratio is 2.18597, indicating that the project generated positive result. In addition, Kruskal-Wallis and Mann Whitney Test result show that the project produced significant statistically different profit compared to the previous period.

Tomato (Lycopersicon Esculentum Mill.) is one of the popular fruit vegetables, especially rich in vitamins, minerals, and antioxidants. Inconsistent light intensity, due to unfavorable weather conditions, reduced tomato performance. Response of one tomato variety (Diamante Max F1), under different light intensities (T1: Control, T2: Single net T3: Double net,) was assessed in field trials. The experimental design was a randomized complete block design (RCBD). Effects of different light intensities were measured in terms of plant height, number of days to flower, number of fruits, the weight of fruits, yield per hectare, and light intensity received in every treatment. All results were significantly different at a 1% level of significance for all parameters. Treatment 2 manifested the highest mean for plant height, treatment 1 for the number of days to flower, and treatment 3 for the number of fruits. Treatment 3 obtained the highest yield per hectare and Treatment 1 for the highest light intensity received per treatment. Treatment 2 has the least mean for all parameters measured, in conclusion, the effect using a double net is highly recommended in tomato production.

The definition of risk in the obstetric structure and its impact on a particular health phenomenon determines the model of work aimed at increasing safety for patients and staff. Preventable events are used as a measure of problems in different sectors, in the organization of work, which also determines the behavior of managers from different hierarchical levels. These are events that would not have happened if there were no strong exposure to a factor or gaps in standard health interventions in obstetric care. Methods: a survey was conducted among medical persons in obstetric structures of the city of Varna. The data is processed using statistical software. Results and discussion: significant results relevant to the definition of risks in obstetric practice have been identified. Proper management of risk situations requires an impact on the causes of complications, which increases the quality of the medical service and ensures patient safety. More than 80% of the risks are determined by acute complications during pregnancy and childbirth, by the urgency and time to manage them. Conclusion: obstetric care requires a continuous audit of the activities, structure and resources and the application of written rules for all possible and rare situations, consistent with the established guidelines and rules of Conduct, which ensure patient safety and workplace safety for employees, in accordance with the legal framework defining medical practice.

Indonesia, with abundant diversity, encompasses a diverse array of ethnicities, cultures, languages, and religions, presenting both advantages and vulnerabilities. Exploiting these diversity and religious factors, extremist groups disrupt national harmony due to a lack of proper understanding of religious doctrine. The escalating intolerance and fanaticism, particularly in Java, Indonesia, pose a clear and imminent threat, resulting in violations of freedom of religion and endangering the preservation of cultural diversity. To delve into these issues and underscore the significance of countering religious extremism, this study employs a qualitative research methodology. The study's findings encompass four key discussions: the disruption of culture caused by religious extremism, the utilization of the Javanese cultural value "tepa selira" to promote religious tolerance, the understanding of religious values and tolerance as fundamental elements for fostering peace amidst diversity, and the instilling Pancasila values to prevent religious extremism. In conclusion, effective measures to counter religious extremist ideologies involve promoting tolerance in education, reinforcing Pancasila's values, empowering societal figures, and fostering collaboration between the government, law enforcement agencies, and individuals. These efforts should focus on instilling peaceful religious guidance and embracing the principles of Pancasila throughout the Indonesian people, thereby effectively preventing the proliferation of religious extremism.

This article shows the existence of a trade-off between the economy and safety in the acceptance of the New Normal Policy for the tourism industry. To prove the existence of the trade-off, path analysis was used to test the mediating effect of the Economic Impact of Pandemic Covid-19 in the prediction of Acceptance Toward New-Normal Policy with the Danger of The Pandemic Covid-19 as the predictor. The result shows that mediation exists, thus trade-off also exists. It means that in the current Pandemic Covid-19 situation, people prefer the economy more than health and safety since they understand that the NewNormal Policy will ensure their health and safety while pursuing the economy. This article contributes to presenting a different method for measuring trade-offs, other than Discreet Choice Experiments (DCE) which is widely used as a method to measure trade-offs. Having proved that trade-off exists, this article recommended that government should always educate the citizen about the danger of the pandemic. This is important so that they will pursue the economy safely and responsibly.

The people of Taiwan have pioneered and developed in Taiwan for 400 years with Confucianism, a Chinese national culture, as their regular proper path. Confucianism, as the mainstream of traditional Chinese culture, has carried many important responsibilities in determining the direction of Taiwan's cultural development. Confucianism in Taiwan after the Restoration has emerged as "official Confucianism" and "folk Confucianism" with different orientations of purpose. We interpret "official Confucianism" and "folk Confucianism" through historical narratives, and summarize the experience of the development of Confucian thought in Taiwan since the Restoration, as well as the dialectical imagery between it and tradition and modernization. In the process of modernizing Confucianism in Taiwan after the Restoration, a paradigm shift in research has occurred, i.e., a shift from political interpretation to a literary-historical interpretive research paradigm, and a shift from "discussing politics with history" to "talking about history with history".
