Health quarantine is an effort to prevent the impact of infectious disease outbreaks that can attack a place, region, even a country, by closing access in and out and limiting the activities or activities of people in the area that is implementing quarantine. For the sake of implementing a proper health quarantine, it is necessary to pay attention to and consider several factors, such as the economic condition of the community, health services, educational services, and working conditions. The implementation of health quarantine is the responsibility of the Government as a manifestation of the State to be able to fulfill all the factors that can support the implementation of health quarantine in an area without causing new problems in people's lives. The government enforces health quarantine with various patterns, such as the implementation of Large-Scale Social Restrictions (PSBB) to the Enforcement of Restrictions on Community Activities (PPKM). As a state of law, Indonesia certainly underlies the implementation of health quarantine by referring to the constitution of the State of Indonesia, namely Law number 6 of 2018 concerning Health Quarantine. The purpose of this study is to analyze the implementation of Article 55 of Law Number 6 of 2018 concerning Health Quarantine in Bandar Lampung City and analyze the fulfillment of citizens' rights in the implementation of Community Activity Restrictions (PPKM) in Bandar Lampung City. The method used in this research is normative juridical and empirical juridical. The data that has been systematically arranged were analyzed qualitatively. In this data analysis process, a series of data that has been systematically arranged according to its classification, is then described and analyzed in a normative and empirical juridical manner, namely the approach taken based on the main legal material by examining theories, concepts, principles and laws and regulations related to this research as well as the results of interviewing parties related to the results of this study.

Authors:   University of Manchester, Pearson Amelia , McPhillips Rebecca , Clarkson Paul , Allen Rosie , Robinson Catherine
Published: October 2022

Review question / Objective: The primary objective of this scoping review is to understand the extent and type of evidence in relation to moral injury in social work staff. The secondary objective is to establish how moral injury has been defined in the literature in the context of social work. The review question is: what is currently known about moral injury in social work staff? Background: Moral injury is the lasting psychological, spiritual and social harm caused by committing, experiencing or observing transgressions of deeply held moral values, beliefs and expectations (Haight et al., 2016). The concept of moral injury was developed and subsequently researched with populations of US veterans. Core symptomatic features of moral injury are guilt, shame, spiritual/existential conflict, and a loss of trust in self, others, and/or transcendental ultimate beings (Jinkerson, 2016). Secondary symptomatic features include depression, anxiety, anger, re-experiencing the moral conflict, self-harm, and social problems (Jinkerson, 2016).

The results of drilling deep wells in recent years have made it possible to refine the internal structure, substantiate new objects in the Late Devonian complex, and reassess the prospects for oil and gas potential and predicted oil and gas resources in the south of the Caspian basin.
A Study on the Legal Status of the Self-Governing Rights of Outside-Law Labor Union
Authors:   National Association of Korean Local Government Studies, Kim Hyojin , Kim Myongjun , Kim Eun-Sik
Published: October 2022

Workers are free to organize or join labor unions and are assured labor's three primary rights. The guarantee of workers' right to organize under the Constitution and the labor union under the Labor Union Act should be finished the report of the establishment by organizing independently with workers becoming the main body and by having the qualification of not conforming to the active and passive requirements with the aim of improving and maintaining the working conditions and of enhancing other workers’ economic and social position.
The administrative agency's recent notification of non-legal union to teachers' union caused a considerable social controversy in relation to the existence of labor unions. This outlawed trade union notification system is what raises a fundamental question about the legal status of a trade union and is what determines the existence of labor unions under the leadership of the administrative authorities, thereby bringing about various constitutional problems. This system has problems such as the regulatory autonomy, the over-packing of risks, the excessive intervention by the administrative agency, and the weakening of workers' right to a trial.
When a labor organization of meeting the substantial requirements for a trade union does not receive a certificate of the establishment report, it is considered to be just unable to get a certain amount of protection such as the labor dispute mediation and the application for relief of unfair labor practices, but to be capable of being protected general rights, which are recognized by the subjects of enjoying the basic labor rights. Also, an individual worker who is a member of the organization may apply to the Labor Relations Commission for relief in own name or in the name of the organization concerned when dismissal or other disadvantageous treatment thereof corresponds to an unfair labor practice. When an employer inflicts a damage by infringing on the legitimate unity activities of the organization, the organization needs to be regarded as being capable of claiming the damages for illegal activities.
Particle Acceleration Controlled by Ambient Density in the Southwestern Rim of RCW 86

Published: October 2022

The physics of particle acceleration at supernova remnant (SNR) shocks is one of the most intriguing problems in astrophysics. SNR RCW 86 provides a suitable environment for understanding the physics of particle acceleration because one can extract the information on both accelerated particles and acceleration environment in the same regions through the bright X-ray emission. In this work, we study X-ray proper motions and spectral properties of the southwestern region of RCW 86. The proper motion velocities are found to be ∼300–2000 km s−1 at a distance of 2.8 kpc. We find two inward-moving filaments, which are more likely reflected shocks rather than reverse shocks. Based on the X-ray spectroscopy, we evaluate thermal parameters such as the ambient density and temperature, and nonthermal parameters such as the power-law flux and index. From the decrease in flux over time of several nonthermal filaments, we estimate the magnetic field amplitudes to be ∼30–100 μG. Gathering the physical parameters, we then investigate parameter correlations. We find that the synchrotron emission from thermal-dominated filaments is correlated with the ambient density n

The Effect of Light Deflection by Solar System Objects on High-precision Square Kilometre Array Astrometry
Authors: Li Yingjie , Xu Ye , Bian Shaibo , Lin ZeHao , Li JingJing , Liu DeJian , Hao Chaojie
Published: October 2022

We have computed the deflection angles caused by 195 objects in the solar system, including 177 satellites, and eight asteroids; 21 satellites and six asteroids can bend light from distant compact extragalactic sources by more than 0.1 μas, and 14 satellites, and the asteroid Ceres can deflect light by more than 1.0 μas. We calculated the zones and durations of perturbations posed by the gravitational fields of five planets (excluding Earth, Jupiter, and Saturn), Pluto, and Ceres, where the perturbations would affect astrometry measured with the Square Kilometre Array (SKA). Perturbed zones with deflection angles larger than 0.1 and 1.0 μas appear as ribbons. Their widths range from dozens of degrees for Uranus, Neptune, and Venus to several degrees or less for other objects at 0.1 μas, and from ∼16° for Venus to several degrees or less for other objects at 1.0 μas. From the calculated perturbation durations, the influence of the gravitational fields of selected objects can be divided into four levels: (i) hardly affects SKA astrometry, (ii) may have little effect, (iii) may have a great effect on single-epoch astrometry, and (iv) may greatly affect both single- and multiepoch astrometry. The objects corresponding to these levels are (i) Ceres, (ii) Pluto, (iii) Mercury and Mars, and (iv) other objects.
SN 1961V: A Pulsational Pair-instability Supernova
Authors: Woosley S. E. , Smith Nathan
Published: October 2022

We explore a variety of models in which SN 1961V, one of the most enigmatic supernovae (SNe) ever observed, was a pulsational pair-instability supernova (PPISN). Successful models reproduce the bolometric light curve of the principal outburst and, in some cases, the emission 1 yr before and several years afterward. All models have helium-rich ejecta, bulk hydrogenic velocities near 2000 km s−1, and total kinetic energies of (4−8) × 1050 erg. Each eventually leaves behind a black hole remnant. Three subclasses of PPISN models are explored, each with two different choices of carbon abundance following helium burning. Carbon is an important parameter because shell carbon burning can weaken the explosion. The three subclasses correspond to situations where SN 1961V and its immediate afterglow were (a) a single event, (b) the first of two or more pulsational events separated by decades or centuries, or (c) the latter stages of a complex explosion that had already been going on for a year or more. For the low-carbon case, the main-sequence mass for SN 1961V’s progenitor would have been 100−115 M
⊙, its pre-SN helium core mass was 45−52 M
⊙, and the final black hole mass was 40−45 M
⊙. For the high-carbon case, these values are increased by roughly 20%−25%. In some PPISN models, a ∼1040 erg s−1 star-like object could still be shining at the site of SN 1961V, but it has more likely been replaced by a massive accreting black hole.
Testing Relativistic Reflection Models with GRMHD Simulations of Accreting Black Holes
Authors: Shashank Swarnim , Riaz Shafqat , Abdikamalov Askar B. , Bambi Cosimo
Published: October 2022

X-ray reflection spectroscopy is currently one of the leading techniques for studying the inner part of accretion disks around black holes, measuring black hole spins, and even testing fundamental physics in strong gravitational fields. However, the accuracy of these measurements depends on the reflection models employed for the spectral analysis, which are sometimes questioned. In this work, we use a general relativistic magnetohydrodynamic code to generate a thin accretion disk in Kerr spacetime and ray-tracing techniques to calculate its relativistically broadened reflection spectrum. We simulate NuSTAR observations and we test the capability of current reflection models to recover the correct input parameters. Our study shows that we can measure the correct input parameters in the case of high inclination angle sources, while we find some minor discrepancies when the inclination angle of the disk is low.
The Directly Imaged Exoplanet Host Star 51 Eridani is a Gamma Doradus Pulsator

Published: October 2022

51 Eri is well known for hosting a directly imaged giant planet and for its membership to the β Pictoris moving group. Using 2 minute cadence photometry from the Transiting Exoplanet Survey Satellite (TESS), we detect multiperiodic variability in 51 Eri that is consistent with pulsations of Gamma Doradus (γ Dor) stars. We identify the most significant pulsation modes (with frequencies between ∼0.5 and 3.9 cycles day−1 and amplitudes ranging between ∼1 and 2 mmag) as dipole and quadrupole gravity modes, as well as Rossby modes, as previously observed in Kepler γ Dor stars. Our results demonstrate that previously reported variability attributed to stellar rotation is instead likely due to γ Dor pulsations. Using the mean frequency of the ℓ = 1 gravity modes, together with empirical trends of the Kepler γ Dor population, we estimate a plausible stellar core rotation period of

days for 51 Eri. We find no significant evidence for transiting companions around 51 Eri in the residual light curve. The detection of γ Dor pulsations presented here, together with follow-up observations and modeling, may enable the determination of an asteroseismic age for this benchmark system. Future TESS observations would allow a constraint on the stellar core rotation rate, which in turn traces the surface rotation rate, and thus would help clarify whether or not the stellar equatorial plane and orbit of 51 Eri b are coplanar.

λ6355 and strong Fe iii absorption features in their optical spectra at pre-maximum phases, and have long been suspected to be over-luminous compared to normal Type Ia supernovae. In this paper, the pseudo-equivalent width of the Si ii
λ6355 absorption obtained at light curve phases from ≤ +10 days is combined with the morphology of the i-band light curve to identify a sample of 1991T-like supernovae in the Carnegie Supernova Project II. Hubble diagram residuals show that, at optical as well as near-infrared wavelengths, these events are over-luminous by ∼0.1–0.5 mag with respect to the less extreme Branch SS (1999aa-like) and Branch core-normal supernovae with similar B-band light-curve decline rates.

The wall-broken Ganoderma lucidum spores are widely used in recent years in the belief that active components inside the spores are better released and well absorbed when taken orally. In this study, the sporoderm of G. lucidum was broken by autoclaving at a high temperature. The powder of wall-broken spores was then extracted by soaking with ethanol at different concentrations (50 %, 70 % and 96 %). The 70% and 50% ethanol extracts had the highest total triterpenoid content, in which ganoderic acid A was predominant. In the DPPH free radical scavenging test, 70% ethanol extract exhibited the highest in vitro antioxidant activity. This 70% ethanol extract was also safe in mice at the dose of 2,000 mg/kg body weight. Moreover, this extract protected the liver from acute injury induced by cyclophosphamide. Indeed, the pretreatment by oral administration of 70% ethanol extract prevented serum ALT and AST activities elevation and attenuated hepatic MDA formation and GSH depletion following administration of cyclophosphamide in mice.

Authors: Rohanda Boy Ardi , Jusuf Nelva Karmila
Published: October 2022

Platelet-rich plasma (PRP) or autologous platelet gel, plasma-rich growth factors, and platelet-concentrated plasma are blood component that is rich in thrombocytes on a small volume of plasma. There were seven primary growth factors that actively secreted by thrombocytes including platelet-derived growth factor, transforming growth factor-β, vascular endothelial growth factor, epidermal growth factor, fibroblast growth factor, connective tissue growth factor, and insulin-like growth factor-1. PRP application in cosmetic dermatology includes tissue regeneration, wound healing, repairing scar tissue, skin rejuvenation, and being used in alopecia patients. PRP could accelerate soft-tissue formation in the subdermal, activate fibroblast formation and new collagen deposition, and formation of blood vessels and fat cells. PRP is also considered a potential therapy for accelerating hair growth for alopecia.

Authors: Bento Matheus , Jameson Mary Liz , Seidel Matthias
Published: October 2022

The phytophagous scarab genus Macraspis MacLeay (Scarabaeidae, Rutelinae, Rutelini) is reviewed from the Brazilian Amazon region. Three new species are described and illustrated from the states of Amazonas, Pará, and Rondônia: M. buehrnheimisp. nov., M. opalasp. nov., and M. phallocardiasp. nov. Two species, Macraspis fernandezi Neita-Moreno and M. oblonga Burmeister, are recorded for the first time in Brazil (new country records). Macraspis maculata crosarai Soula is a new synonym of Macraspis maculata Burmeister; hence this species no longer includes subspecies. Furthermore, Macraspis cincta parensis Soula, 2005 is deemed unavailable under the provisions of ICZN Articles 16.4.1 and 16.4.2. An illustrated key to 15 species and subspecies of Macraspis from the Brazilian Amazon enables identification of this speciose leaf chafer genus.
Alpinistična avtobiografija v enem grafu: primer Zaplotnik
Authors: Habjan Jernej
Published: October 2022

Članek umešča Pot, knjigo slovenskega alpinista Nejca Zaplotnika iz leta 1981, v kanon alpinistične avtobiografije, v za ta namen razvit graf tega žanra in v Zaplotnikovo biografijo. Na kanoničnost knjige pokaže s pomočjo omemb, ki jih je deležna v drugih predstavnicah žanra, in s pomočjo citiranosti, ki jih je določen odlomek iz Poti deležen v alpinistični literaturi ter v njeni kritiški in znanstveni refleksiji. Osrednje mesto Zaplotnikove knjige v slovenski alpinistični literaturi, primerljivo z mestom knjige Hermanna Buhla Achttausend drüber und drunter (Nanga Parbat) v svetovnem merilu, članek razlaga s tem, da kronotop Poti realizira celotno pripovedno strukturo svojega žanra. To strukturo v članku rekonstruira graf, utemeljen v opoziciji med vertikalno (paradigmatsko, metaforično) in horizontalno (sintagmatsko, metonimično) potjo. Nazadnje to strukturo članek zasleduje tudi v biografiji Nejca Zaplotnika, ki se je po izidu Poti lotil pisanja reportaže za Teleks in romana Peter Simsen, med katerima (in znotraj katerih) lahko znova odkrijemo strukturo, utemeljeno na opoziciji med vertikalno in horizontalno potjo.
A mini guideline study for fly ash-based alkali activated foam masonry units
Authors: Kurtulus C. , Baspinar M.S.
Published: October 2022

This study examined the preparation of fly ash-based foam geopolymer recipes with the experimental design method and data analysis with the SPSS program. A total of 54 prescriptions were used in the studies, which investigated six different variables. Strength, density, and thermal conductivity analyses were performed. Values were in the range of 0.57-2.75 MPa for strength, 344-592 kg/m3 for density, and 0.089-0.132 for thermal conductivity. Three variables were identified with each having the most significant effect on strength and density values. H2O2, curing temperature, and expanded perlite had the most effect on strength, while H2O2, curing temperature, and alkali concentration had the most significant effect on density. Most influential parameters are plotted on ternary graphs to ensure that the foam concrete (CLC) masonry units used in all types of masonry walls, whether load-bearing or not, can operate under the specified performance conditions.

Indigenous Conflict Resolution Mechanism as Reconciliatory and Therapeutic
Authors: Tweneboah Seth , Richards Anthony
Published: October 2022

This chapter explores the role of traditional methods of social control that deploy the power of the deities as a missing dimension of justice delivery. The authors present the rituals associated with deploying the traditional mechanism of control as both reconciliatory and therapeutic. Drawing on both historical and contemporaneous instances from Ghana and the Caribbean, the chapter contends that the continuous reliance on African spirit-based justice delivery method betrays not only the insufficiencies in the Western superimposed adversarial legal system but also a tacit and open rejection of this imported system. The chapter interrogates the prospects and pitfalls of indigenous Africa and its diasporan conflict resolution mechanism.

Authors: Mishra Akshat , Kaushik Swetank , R. Srinivasa Perumal , Chowdhary Chiranji Lal
Published: October 2022

The notion of agile supply chains is gaining traction in academia and has been enthusiastically adopted by private corporations. A variety of factors differentiate agile supply networks. They should not only be network-based but also market-sensitive, with tightly linked virtual and crucial operations. If agile supply chains are to adapt for ever-faster turnaround time towards both volume and variety changes, they must integrate supply and demand. The agile supply chain must be able to swiftly modify the output to satisfy customer needs and move from one version to the next. Of course, information technology is essential to the smooth running of agile teams. However, this chapter will focus on two additional essential facilitators of supply chains. Agility, which has gotten less emphasis yet is vital to the success of these kinds of procedures, has gotten less attention.

Authors: Pinkovetskaia Iuliia
Published: October 2022

The purpose of study was to evaluate the indicators characterizing the development of the healthcare system in the regions of Russia. The study used official statistical information on the activities of medical organizations located in all 82 regions of Russia for 2020. The density functions of the normal distribution were used as models. The research showed that on ten thousand people living in the region are an average of 48 doctors, 85 hospital beds, 289 patients who were served daily in organizations engaged in outpatient treatment. These indicators are higher than in many other countries, which creates prerequisites for the development of emotional intelligence in the Russian healthcare sector. In most regions the salary in the healthcare sector did not differ significantly from the average salary in the corresponding region. The proposed methodological approach and the results obtained have a scientific novelty, since the assessment of regional features of medical care in the regions of Russia has not been carried out before.

Authors: Rudchenko Dmitry , Serdyuk Vasyl , Dyuzhilova Natalia
Published: October 2022

The article provides an analytical literature review on the production of cements and cement materials with active mineral additives. The tendency exists to reduce a clinker component in cement and cement materials via use of blast-furnace granulated slag or other additives; it reduces expenses for cement production and improves performance of autoclaved aerated concrete (AAC). Inexpensive and affordable local effective pozzolanic additives can improve the economic and environmental attractiveness of autoclaved aerated concrete production. The performed studies have shown improved physical and mechanical properties of autoclaved aerated concrete with metakaolin, which is a product of low-temperature firing of kaolin.

Authors: Sudha D. , Suganya R. , Revathi A. , Yoghaananthan K. , Sivaprakash V.
Published: October 2022

The low weight and high strength ratio of titanium alloy make TiO2 nanotubes ideal for biomedical applications. Increasing the oxidation process has recently been studied as a means of encouraging the formation of nanotubes. This study synthesizes the TiO2 nanotubes with different input voltages. There was an increase in nanotube growth rate as a result of de-ionized water in the electrolyte, as well as an increase in the input potential, which favours oxidation. An analysis of the surface morphology suggests that rib structures were generated in the area where corrosion results were greatly elevated. X-ray diffraction and nanoindentation were used to study phase transformations and nanohardness respectively.
