Antiviral and Virucidal Properties of Essential Oils and Isolated Compounds – A Scientific Approach
Authors: Reichling Jürgen 
Published: June 2021

AbstractEssential oils and isolated essential oil compounds are known to exert various pharmacological effects, such as antibacterial, antifungal, antiviral, anti-inflammatory, anti-immunomodulatory, antioxidant, and wound healing effects. Based on selected articles, this review deals with the potential antiviral and virucidal activities of essential oils and essential oil compounds together with their mechanism of action as well as in silico studies involving viral and host cell-specific target molecules that are indispensable for virus cell adsorption, penetration, and replication. The reported in vitro and in vivo studies highlight the baseline data about the latest findings of essential oils and essential oil compounds antiviral and virucidal effects on enveloped and non-enveloped viruses, taking into account available biochemical and molecular biological tests. The results of many in vitro studies revealed that several essential oils and
essential oil compounds from different medicinal and aromatic plants are potent antiviral and virucidal agents that inhibit viral progeny by blocking different steps of the viral infection/replication cycle of DNA and RNA viruses in various host cell lines. Studies in mice infected with viruses causing respiratory diseases showed that different essential oils and essential oil compounds were able to prolong the life of infected animals, reduce virus titers in brain and lung tissues, and significantly inhibit the synthesis of proinflammatory cytokines and chemokines. In addition, some in vitro studies on hydrophilic nano-delivery systems encapsulating essential oils/essential oil compounds exhibited a promising way to improve the chemical stability and enhance the water solubility, bioavailabilty, and antiviral efficacy of essential oils and essential oil compounds.

Published: June 2021

AbstractPurpose To evaluate the relationship between kinesiophobia and patient's return to sport after shoulder stabilization surgery. The hypothesis was that kinesiophobia represents an independent factor correlated to the difference between preinjury and postoperative level of sport.Methods This study retrospectively evaluated 66 patients (mean age: 35.5, standard deviation [SD] = 9.9 years) and at a mean follow-up of 61.1 (SD = 37.5) months after arthroscopic Bankart's repair or open Bristow–Latarjet procedure. Kinesiophobia was assessed with the Tampa Scale for Kinesiophobia (TSK); return to the preinjury sport was assessed by the difference between baseline and postoperative degree of shoulder involvement in sport (D-DOSIS) scale. The Western Ontario Shoulder Instability index (WOSI) was used to evaluate participants' perceptions of shoulder function.Results TSK showed correlation with D-DOSIS (ρ = 0.505, p < 0.001) and the WOSI score (ρ = 0.589, p < 0.001). There was significant difference in TSK and WOSI scores between participants who had and had not returned to their previous level of sport participation (p = 0.006, and 0.0001, respectively).Conclusion This study demonstrated that kinesiophobia is correlated to the return to sport after shoulder stabilization surgery.Level of Evidence Level IV, retrospective case series.

Published: June 2021

Abstract
Background Discoid lateral meniscus is the most frequent variant of the meniscus. Few studies have focused on the histology of discoid menisci. The aim of the present study was to report the histological findings of discoid lateral meniscus in children and adolescents, after arthroscopic partial resection, to give a possible explanation of its developmental etiology.
Methods Five patients aged 9, 10, 13, 15, and 17 years were operated on for a 1-piece excision of a discoid lateral meniscus, and the specimens were histologically examined.
Results The extracellular matrix showed a different distribution and characteristics depending on the different side of the meniscus. Irregularly oriented collagen fibers in discoid lateral meniscus were found. Cells of different shapes were observed depending on the surficial or deep location in the tissue. There were no blood vessels in the inner part of discoid lateral meniscus.
Conclusion The findings of the current study seem to confirm that discoid lateral meniscus arises from variant morphogenesis. Furthermore, the altered distribution and shape of the cells and disorganization of collagen fibers (irrespectively of the age of the patients) may predispose discoid lateral meniscus to degeneration, damage, and tear in young patients also.

Published: June 2021

AbstractKnee dislocation is one of the few real orthopaedic emergencies. It is a serious but relative uncommon injury, representing less than 0.02% of all orthopaedic injuries. Especially posterolateral knee dislocation is much rarer condition that is often missed or misdiagnosed. The main feature of this very rare condition is to be irreducible by closed reduction due to the interposition of soft tissues inside the enlarged medial joint space, such as the medial capsule and retinaculum, vastusmedialis, and medial meniscus. The pathognomonic sign of a posterolateral knee dislocation is the anteromedial distal thigh transverse “pucker” or “dimple sign.” We report the case of an 87-year-old man who sustained an irreducible posterolateral fracture dislocation of the knee after being hit by car which has been treated with rotating hinge knee replacement with 1-year of follow-up.
Improvement of the far-infrared optical property for glasses by plasma-assisted dispersion of fluorocarbon species into the shallow surface
Authors: Sato Kiminori , Ito Kenji 
Published: June 2021

Owing to global warming together with the demands for thermal energy storage in diverse fields, there is demand for transparent glasses achieving reflection of the short-wave far-infrared (IR) light from solar radiation while also absorbing the longer wavelength part. Here, we performed the plasma-assisted ion implantation using a desktop-type low-pressure fluorocarbon plasma generator system to improve the optical properties of transparent soda-lime glasses. Investigations using positron annihilation techniques for the plasma-treated glass demonstrated that the fluorocarbon species occupy the sub-nanoscale interstitial sites available in the glass network of the soda-lime glass as the intrinsic open spaces, forming an implantation layer in the shallow-surface region around a depth of 50 nm. As revealed by optical spectroscopy, the subsurface layer, due to the implanted fluorocarbon species, significantly cuts off the short-wave far-IR light around a wavelength of ∼3 µm and also acts as the absorber of the longer wavelength region from 7 to 12 µm. Plasma treatment could be a promising tool to improve the optical properties in the IR light region for various materials.

Published: June 2021

The energy consumption of high-power microwave sources has attracted much attention in the research field of high-power microwaves. One way of decreasing the energy consumption is to reduce the guiding magnetic field. In this work, a high-efficiency transit-time oscillator is proposed with a low guiding magnetic field. In order to enhance the modulation depth of electrons and increase the conversion efficiency under a low guiding magnetic field, two bunchers are adopted to modulate the electron beam. 2.5D simulation results show that the proposed device generates microwaves with a power of 3.6 GW and a frequency of 4.31 GHz. The power conversion efficiency is 40% and the modulation depth is 125% when the guiding magnetic field is only 0.5 T. In addition, a 3D simulation verifies the results.

Main text
Carbon monoxide (CO) in nitrogen was one of the first types of gas mixtures used in an international key comparison. This comparison dates back to 1998 (CCQM-K1a) [1]. Another key comparison on carbon monoxide is the CCQM-K51 at the lower amount fraction of 5 μmol/mol. Since then, many National Metrology Institutes (NMIs) have developed Calibration and Measurement Capabilities (CMCs) for these mixtures. Recently, NMIs in the APMP region have actively participated in international comparisons to provide domestic services. At the 2017 APMP meeting, several NMIs requested a CO comparison to establish CO/N2 certification for supporting industrial needs, which was to be coordinated by KRISS. Consequently, this supplementary comparison provides an opportunity for APMP regional NMIs to meet their industrial needs. It is a replica of APMP.QM-S9.[2]

Carbon dioxide (CO2) in nitrogen was one of the first types of gas mixtures performed at an international key comparison. The comparison dates back to 1998 (CCQMK1a) [1]. Since then, many National Metrology Institutes (NMIs) have developed Calibration and Measurement Capabilities (CMCs) for these mixtures. The international comparison of CO2 at ambient level through CCQM-K52 was compared in 2007 [2]. Recently, NMIs in the APMP region have focused on developing emission standards for regulating CO2 released by various powered vehicles such as automobiles (motor cars). At the 2017 APMP meeting, several NMIs requested a CO2/N2 comparison to establish their own standards related with automotive regulation, which was to be coordinated by KRISS. Consequently, this comparison provides a CMC for APMP regional NMIs to develop CO2/N2 CMC claim.

Role of in-situ hydrogen plasma treatment on gate bias stability and performance of a-IGZO thin-film transistors
Authors: Prasad Om Kumar , Mohanty Srikant Kumar , Wu Chien Hung , Yu Tsung Ying , Chang Kow Ming 
Published: June 2021

Abstract
This work investigates the effect of an in situ hydrogen plasma treatment on gate bias stability and performance of amorphous InGaZnO thin-film transistors (TFTs) deposited by using atmospheric-pressure PECVD. The H2 plasma-treated a-IGZO channel has shown significant improvement in bias stress induced instability with a minuscule threshold voltage shift (ΔV
th) of 0.31 and −0.17 V under positive gate bias stress (PBS) and negative gate bias stress (NBS), respectively. With the aid of the energy band diagram, the proposed work demonstrates the formation of negative species O2
− and positive species H2O+ in the backchannel under PBS and NBS in addition to ionized oxygen vacancy (Vo) defects at a-IGZO/ZrO2 interfaces are the reason for gate bias instability which could be effectively suppressed with in situ H2 plasma treatment. From the experimental result, it is observed that the electrical performance such as field-effect mobility (μ
FE), on-off current ratio (I
on/I
off), and subthreshold swing improved significantly by in situ H2 plasma treatment with passivation of interface trap density and bulk trap defects.
Infectious disease dynamics in metapopulations with heterogeneous transmission and recurrent mobility
Authors: Cota Wesley , Soriano-Paños David , Arenas A , Ferreira Silvio C , Gómez-Gardeñes Jesús 
Published: June 2021

Abstract
Human mobility, contact patterns, and their interplay are key aspects of our social behavior that shape the spread of infectious diseases across different regions. In the light of new evidence and data sets about these two elements, epidemic models should be refined to incorporate both the heterogeneity of human contacts and the complexity of mobility patterns. Here, we propose a theoretical framework that allows accommodating these two aspects in the form of a set of Markovian equations. We validate these equations with extensive mechanistic simulations and derive analytically the epidemic threshold. The expression of this critical value allows us to evaluate its dependence on the specific demographic distribution, the structure of mobility flows, and the heterogeneity of contact patterns, thus shedding light on the microscopic mechanisms responsible for the epidemic detriment driven by recurrent mobility patterns reported in the literature.

Published: June 2021

Abstract
We study inelastic collisions between CaF molecules and 87Rb atoms in a dual-species magneto-optical trap. The presence of atoms increases the loss rate of molecules from the trap. By measuring the loss rates and density distributions, we determine a collisional loss rate coefficient k
2 = (1.43 ± 0.29) × 10−10 cm3 s−1 at a temperature of 2.4 mK. We show that this is not substantially changed by light-induced collisions or by varying the populations of excited-state atoms and molecules. The observed loss rate is close to the universal rate expected in the presence of fast loss at short range, and can be explained by rotation-changing collisions in the ground electronic state.
Analysis and implementation of the bi-polar slope one algorithm with the content base filtering method in producing culinary place recommendations in kuningan regency
Authors: Suseno Endra , Priantama Rio , Irawan Dede 
Published: June 2021

Abstract
The recommendation system is an analysis model to obtain recommendations that use filtering techniques to produce recommendations as desired. One of the prediction algorithms is Bipolar Slope One which is a development of the Slope One algorithm to predict an event. Previous studies have shown that the results of the recommendations on the Bipolar Slope One algorithm show a mismatch between the type of recommended item and the type of item that has been rated by the active user, because the rating prediction process in the Bipolar Slope One algorithm does not pay attention to the type or content of the item, but pay more attention to the similarity of rating patterns. This study uses the Content-Based Filtering method to form a profile based on the attributes of an item which will make an assessment based on the analysis of the similarity of the user profile with the vector space model. Application users get information about which culinary delights have an item profile that is expected by him. Culinary players get information about what item profile I expect by the User.

Abstract
The application of information technology is a supporting instrument in the administrative process as well as the provision of useful information for all groups to improve performance, one of which is in government. Governments around the world are currently facing “pressure” from various parties to improve the quality of public services and to increase active participation in providing information for the public and it is demanded to be more effective. E-Government can expand public participation where people are allowed to be actively involved in decision-making and policies held by the government. Kuningan District is one of the sub-districts in Kuningan Regency, the obstacle that arise related to community participatory development planning is that there are still many proposals from the sub-district that the Kuningan Regency government has not approved. It needs a means to monitor the progress of its implementation, including the use of information technology to accommodate development planning proposals based on participatory and active roles of the community in the form of e-Participatory application design. This research uses Waterfall system method as system development method. The programming language used in the system is PHP programming language and its database management uses SQL. By implementing the e-Participative application, the Kuningan district government can accommodate suggestions from each village in the Kuningan district area. Besides, this research can be a material consideration for Kuningan District to synergize policies and regulations through strategic plans and development planning proposals in the Kuningan sub-district based on effective and efficient community participation.

Abstract
The aim of this study is to develop a grouping model in order to determine the means of trade and accommodation according to the regions in Indonesia. Research can be a reference for the government to increasing the income of each region in Indonesia equally. Research data were taken from a website that provides government statistical data, namely BPS (Badan Pusat Statistik)-www.bps.go.id The solution is to use data mining techniques with clustering methods. The data test process uses the Rapid Miner software. Three clusters of mapping labels are used, namely the high cluster (K1), the normal cluster (K2) and the low cluster (K3). The results of the rapidminer processing were obtained from the centroid data for high clusters, namely ((1527), (810.4), (5865), (6655.3), (323), (315.1); the medium cluster, namely ((286), (199.591), (1327), (2240.227), (93.227), (140.955)); and the low cluster, namely (139.25), (122.5), (508.833), (919.222), (64.417), (94.444)). The cluster results show that 5 provinces are classified as high in clusters; 13 provinces are classified as medium clusters; and 16 provinces are classified as low clusters. Out of the results of the study, some 47% of areas in Indonesia still have low trade and housing facilities. With this analysis, it is hoped that the government will be able to pay more attention to regions whose revenues are still below average.
