Published: March 2023

Coinfection with hepatitis B virus (HBV) and hepatitis C virus (HCV) in human immunodeficiency virus (HIV) infected individuals results in increased hepatic complications. HBV and HIV viruses are transmitted by blood and unprotected sexual intercourse. People with HIV and HBV coinfection are at increased risk for liver-related morbidity and mortality. HCV-related liver injury progresses more rapidly among people coinfected with HIV. HCV coinfection may also affect the management of HIV infection. This review aims to go over the management of HIV-HCV and HIV-HBV coinfections.

Energy absorption and recoverability of Moore space-filling thin-walled structures
Authors: Wu Changlang , Nguyen-Van Vuong , Tran Phuong
Published: March 2023

This paper proposes novel thin-walled structures inspired by Moore space-filling curves. Nine designs, featuring three fractal hierarchies (1st, 2nd, and 3rd orders) with three different relative densities (20%, 30%, and 40%), were used as cross-sectional configurations of the thin-walled structures. Specimens were manufactured using a material extrusion additive manufacturing technique, fused filament fabrication, with a carbon fiber-reinforced composite. Quasi-static compression tests from in-plane direction were conducted to investigate the influences of fractal hierarchy and relative density on the energy absorption capacity. Finite element models were developed to compare with the experiments and to further explore the 4th order structures. A certain level of compliance and snap-in instability were observed in all the structures. These properties show great potential for such thin-walled structures to absorb more energy by enduring large strain. Among them, the 2nd order structures exhibited the best energy absorption capacity. Furthermore, loading and unloading compression tests were performed on the 2nd and 3rd order structures (relative density of 20%) to evaluate their resilience toward displacement and damages. The residual strain and dissipated energy ratio demonstrated that the 2nd order structure outperformed the 3rd order structure owing to its less compliant feature. The integration of Moore curves with thin-walled structures contributes to great compliance and snap-in instability, offering a new approach to designing lightweight energy absorption structures.

State, Territory, and NatureServe Conservation Listing Status of Taxa in National Park Service Units for use in Determining Appropriate Release of Data
Authors: DeVivo Joe
Published: March 2023

In 2013, Executive Order 13642, Making Open and Machine Readable the New Default for Government Information (GPO 2013), and associated policies issued by the Office of Management and Budget (OMB 2013) mandated that all data be made public by default unless those data are protected from release by one or more authorities. Staff at all National Park Service (NPS) units where the Inventory & Monitoring Division conducts activities identified resources that warrant some level of data protection, and default rules to be used when disseminating information about those resources. In nearly all cases, information about taxa on State and NatureServe lists of species of conservation concern were identified as taxa about which data must be protected from public release. This report documents the creation of a standard dataset of state-, territory-, and NatureServe-designated taxa for each NPS unit to use in developing public-access versions of inventory & monitoring datasets developed by the NPS Inventory and Monitoring Program.

Authors: Babu SK Khadar , Chesneau Christophe , Anthonysamy Victor
Published: March 2023

Time series play a vital role in predicting and forecasting different types of agricultural applications with respect to different types of problems among successive units of observations. Time series forecasting techniques are applied in all areas of statistics, and one of the most important applications includes backscatter generating time-series data using advanced forecasting techniques. Agriculture is a major food sector in the world, and it is also a major income source for low-income people. In this paper, we present two aspects of the rice crop growing time series process. The first one is to identify different types of rice crop growing stages for backscatter datasets, and the second is to make a mathematical time series model for the generation of different data sets. The different operator techniques (DOT) method was introduced to identify different types of rice crop growing stages in a season. We proposed the DOT method for identification of different phenological stages for a short-term crop and adopted first and second-order auto-regressive models for prediction and forecasting of the generating backscatter time series observations. The measures of the quality fit are mean absolute percent error (MAPE), mean percent error (MPE), and mean absolute error (MAE).

The research deals with the probabilistic estimates of annual maximum flood peaks in the upper Chaophraya basin (Thailand) used the extreme value theory, the Block Maxima. The Generalized Extreme Value (GEV) distribution model, the Frèchet distribution (EV2), the extension of the Frèchet distribution such as the Kumaraswamy Frèchet distribution and the new distribution as called the Exponentiated Kumaraswamy Frèchet distribution satisfied the Goodness of fit test (Kolmokorov-smirnov test). The return levels are estimated for 3, 5, 10, 30, 50, 100, 500 and 1000 years which are consistently increasing for designs of flood protection in future. The return period of flood for each stations are estimated.

The investigation of the new distribution and appropriated estimation technique for the flood frequency in upper Chaophraya river basin as we called the Exponentiated Kumaraswamy Frèchet distribution and the differential evolution maximum likelihood estimation were done. We derived the properties of the Frèchet family; such as the Frèchet distribution (EV2), the Kumaraswamy Frèchet distribution (KF) and the Exponentiated Kumaraswamy Frèchet distribution (EKF). We also compared Bias, Variance, Mean Square Error and Mean Absolute Percentage Error for all parameters in each distribution by generating the Frèchet family random number. For the effectiveness of analytical solutions of the parameters we provided the numerical solutions (differential evolution method) to obtain estimates for all parameters by using Scilab program.

Accuracy of flood assessment of extreme event is of fundamental importance for many safety, engineering and financial application. In part of application we provided the probabilistic estimates of annual maximum flood peaks or momentary peak data in the upper Chaophraya river basin (Thailand). The Generalized Extreme Value (GEV) distribution model were used to be gain to compare with as the Frèchet distribution (EV2), the Kumaraswamy Frèchet distribution (KF) and the Exponentiated Kumaraswamy Frèchet distribution (EKF). The Goodness of fit test, the return level and return period were done. The return periods of flood were classified by hazard class using GEV found that in upper Chaophraya river basin flood occurred highly. The result from the Frèchet family also occurred highly, but the return period and return level from the Kumaraswamy Frèchet distribution (KF) quite closed to GEV more than another distribution.

A barge loading conveyor (BLC) is the main means of transporting coal (material handling) from the stockpile to the barge. Disruption of the conveyor which is driven by an electric motor results in the cessation of the coal shipping process, so performance and efficiency in its use must be ensured. The purpose of this research is to see the value of overall equipment effectiveness (OEE) on PT Mitra Barito barge loading conveyor (BLC), which will later be used as a basis for corrective actions and efforts to increase productivity. The method used in this research is a quantitative method where at this stage the value of overall equipment effectiveness (OEE) is calculated which includes three categories of levels of availability, level of performance, and level of quality. Where in looking at the causes of low OEE seen from the proportion of six major losses. The results showed that the average overall equipment effectiveness (OEE) value of 56.19% was considered ineffective because corrective steps still needed to be taken so that it could inhibit barge loading conveyor (BLC) activities. This is affected by slowdowns, tuning, and adjustments, as well as idling and mining stops with high loss proportion values.

Turmeric is a plant that is included in the spice plant category and is also a family medicinal plant (TOGA) which is good for health. However, in the drying process they still use the traditional method of drying in the sun, so this method is less effective because it has to depend on the weather. Therefore there must be a new innovation, namely using a dryer. In this study, the dryer used was an oven that had been designed using a hair dryer as the heat source. The purpose of this study was to determine the performance of the turmeric dryer with a hair dryer as a heat source. This type of research is a pure experimental research. The research object is an oven-shaped dryer that uses a hair dryer as a heat source. After conducting performance tests, the turmeric dryer can work well. This study uses 3 time variants, namely, 30, 60, and 90 minutes. Testing at 55°C was the most efficient time, namely 90 minutes with an initial weight of 200 grams to 118 grams which experienced higher shrinkage than 30 minutes and 60 minutes. The longer the drying time, the better the drying results.

Published: March 2023

This research tries to completely describe the Mayor of Jayapura's call about the draft regional ordinance on the usage of Noken as an alternative to plastic bags at Jayapura City shopping facilities. It is a qualitative study using the social phenomenology paradigm, involving passive participatory observation, interviews, and documentation. It employs Miles and Huberman's flowchart analysis tools. The Mayor's request for the use of Noken bags in shopping decreases the impact of using plastic bags, which are difficult to degrade with soil in a short period of time. The use of the Noken bag also introduces Papuan culture, which has a straightforward and straightforward philosophy. Rational action in the form of an appeal from the Mayor of Jayapura is looked for, in anticipating the problem of plastic trash that is difficult to degrade by soil and minimizing the accumulation of plastic garbage in rivers in the city of Jayapura, which results in annual flooding. The application of Noken, which sets aims and behaviors through norms, has a philosophical connotation that lies beneath Papuans' common understanding, namely simplicity and transparency. Noken establishes a positive relationship between symbolic arrangements in Papuan society, displaying the forms and patterns of life of the Papuan people, particularly in the city of Jayapura, which reflects the meaning of the simple Papuan people and their openness to others in preserving Papuan culture.

Authors: Pechlivanis Christos
Published: March 2023

The Internet of Things (IoT) is proliferating, with thousands of new sensors and equipment going live each month. Despite its lengthy evolution, the Internet of Things has only recently begun to take off in the mass market due to low-cost, reduced-power elements, ubiquitous web access, and high business and consumer interest. The Internet of Things includes anything from intelligent kitchen appliances to smart buildings, smart lighting on streets to automated manufacturing processes, and adaptive home heaters to autonomous vehicles. This research concerns studying and applying Internet of Things (IoT) technology to monitor the supply chain and achieve more sustainable operations by ensuring accurate and real-time data monitoring. In this context, an experimental device is developed to read the values of selected physical quantities from the wine supply chain environment through appropriate sensors. The values are then sent to an IoT platform to facilitate the remote monitoring of the above physical quantities and extract valuable insights from the large volume of data generated. The results show that crucial information can be gathered in real-time, enabling quick decision-making and ensuring safer and more sustainable supply chain operations.

Betzite, ideally Na6Ca2(Al6Si6O24)Cl4, a new cancrinite-group mineral, was discovered in a metasomatically altered (pyrometamorphosed) calcic xenolith, hosted by alkaline basalt at the Bellerberg paleovolcano in the Eastern Eifel region, Rhineland-Palatinate, Germany. The associated minerals are anorthite, phlogopite, diopside, grossular, fluorite, calcite, a tobermorite-like mineral, and vanadoallanite-(Ce). Betzite occurs as colorless hexagonal prismatic crystals up to 2 mm long and up to 0.5 mm thick. The new mineral is brittle, with a Mohs' hardness of 5½. Distinct cleavage on {100} and parting on {0001} are observed. The Dmeas = 2.38(2) g/cm3 and Dcalc = 2.363 g/cm3. Betzite is optically uniaxial (+) with ω = 1.528(2) and ε = 1.545(3). The IR spectrum is given. The chemical composition of betzite is (wt.%; electron microprobe, H2O determined by the modified Penfield method): Na2O 11.88, K2O 4.82, CaO 10.74, MgO 0.21, Al2O3 27.32, Fe2O3 0.68, SiO2 32.84, SO3 1.89, Cl 10.48, H2O 1.10, −O≡Cl −2.37, total 99.59. The empirical formula is Na4.22K1.13Ca2.11Mg0.06(Si6.01Al5.90Fe3+0.09O24)Cl3.25(SO4)0.26(H1.34O0.64). The crystal structure was determined using single-crystal X-ray diffraction data. It is hexagonal, space group P63, a = 12.8166(9) Å, c = 5.3562(3) Å, V = 761.95(12) Å3 (at a temperature of 100 K) and Z = 3. Betzite is a dimorph of quadridavyne, with a disordered distribution of extra-framework components occupying channels. The strongest lines of the powder X-ray diffraction pattern [d, Å (I, %) (hkl)] are: 11.14 (31) (100), 4.833 (93) (101), 3.715 (95) (300), 3.313 (100) (211), 2.787 (37) (400), 2.681 (56) (002, 131), 2.474 (35) (112, 401), 2.146 (24) (330). The mineral is named in honor of the German amateur mineralogist Volker Betz (b. 1947).
Mineralogy of Pt-Pd sulfides: The Redefinition of Braggite and Vysotskite (with Comments on the Extent of Solid Solution in the PtS–PdS Binary)
Authors: CABRI Louis J. , McDONALD Andrew M.
Published: March 2023

A re-evaluation of data relating to the crystal structures, phase equilibria, and ideal chemical formulae of the key minerals belonging to the PtS–PdS binary, namely vysotskite, braggite, and cooperite, has led to redefinitions of the ideal chemical formulae for vysotskite and braggite. Results show that vysotskite and braggite are isostructural and crystallize in the space group P42/m. Their crystal structures contain three Me sites and a single S site, giving rise to the general crystal-chemical formula Me(1)2Me(2)2Me(3)4S8. Ordering of Pt and Pd leads to the revised ideal formula of Pd2Pd2Pd4S8 (Z = 1) for vysotskite, which can be simplified to PdS (Z = 8), and a revised ideal formula of Pd2Pt2Pt4S8 (Z = 1) for braggite, which can be simplified to PdPt3S4 (Z = 2). Cooperite, ideally PtS (Z = 8), crystallizes in a related, but different, space group, P42/mmc. Its crystal structure contains a single Me and S site. Both Pt and Pd are disordered over the Me site but with Pt > Pd . Oversimplification of the ideal chemical formulae for all these minerals and failure to consider crystal-structure implications has led to confusion in the literature.

Consideration of experimental data combined with that for minerals from world-wide occurrences suggests complete solid solution between vysotskite and braggite, but of a more limited degree between cooperite and braggite, consistent with what would be expected when their respective crystal structures are considered. The maximum Pt possible in braggite should correspond to (Pd0.51Pt0.49)Σ1Pt3S4 (or Pd0.51Pt3.49S4); Pt:Pd = 0.87, which requires Pd 6.29, Pt 78.86, S 14.85, total 100.00 wt.%) and the maximum Pd content, to Pd(Pt0.505Pd0.495)Σ1(Pt1.505Pd0.495)Σ2S4 (or Pd1.99Pt2.01S4); Pt:Pd = 0.50, which requires Pd 28.93, Pt 53.56, S 17.52, total 100.00 wt.%). In light of the complete solid solution between vysotskite and braggite, the 50% rule should be applied to compositions between them. Thus, within the PtS–PdS binary, it is recommended that (1) vysotskite be used for those minerals having compositions ranging from 100 to 56.5 mol.% PdS; (2) braggite, for those having compositions that range from 56.5 to 13 mol.% PdS; and (3) cooperite, for those having <13 mol.%.

Tyrimo tikslas. Išanalizuoti moterų gimdymo patirties vertinimą ir jo sąsajas su socialiniais demografiniais, gimdymo eigos ir priežiūros veiksniais Lietuvoje. Tyrimo metodai. Tyrimo duomenys buvo renkami, vykdant tarptautinį „Babies Born Better“ tyrimą apie moterų gimdymo priežiūros patirtis. Tyrime buvo kviečiamos dalyvauti moterys, gimdžiusios ne ankščiau nei prieš penkerius metus. Jų buvo prašoma užpildyti anoniminę anketą internetu. Į analizę įtraukti 603 moterų, gimdžiusių Lietuvoje, duomenys. Rezultatai. 76,5 proc. tyrime dalyvavusių moterų pagimdė savaiminiu būdu. Didesnė dalis (54 proc.) moterų teigė, kad gimdymas iš esmės buvo labai teigiama arba gana teigiama patirtis, beveik 25 proc. moterų nurodė, jog gimdymas iš esmės buvo gana neigiama arba labai neigiama patirtis, 21 proc. atsakė, kad tai buvo iš dalies teigiama, iš dalies neigiama patirtis. Gimdymo patirties vertinimas nebuvo susijęs su moterų socialiniais-demografiniais veiksniais bei gimdymo priežiūrą vykdančių specialistų komandos sudėtimi. Labiau teigiamai gimdymo patirtį vertino natūraliais gimdymo takais ir be medicininių intervencijų gimdžiusios moterys, palyginus su skubaus cezario pjūvio operacijos atvejais.

Review question / Objective: The effectiveness and safety of different surgical approaches for papillary thyroid carcinoma of isthmus(PTCI) were evaluated by assessing tumor recurrence, postoperative complications, and prognostic outcomes in patients with PTCI after total thyroidectomy and less-than-total thyroidectomy. Condition being studied: In 2015, the ATA stated in the treatment guidelines for PTC that total or near-total thyroidectomy is recommended for tumors >4 cm in diameter, cN1, cM1, or the apparent presence of extra thyroidal extension (ETE). For tumor diameter of 1-4 cm, no ETE and no lymph node metastasis, total or near-total thyroidectomy is feasible. However, the scope of surgery and lymph node dissection for PTCI is not clearly defined. Therefore, in clinical practice, there are many controversies among domestic and foreign scholars regarding the scope of surgery for patients with PTCI, and it is difficult to draw credible conclusions due to the low incidence of PTCI and the relatively small number of cases selected from various clinical studies. And there is no relevant meta-analysis, so it is clinically significant to conduct this study.

Agricultural production in the face of climate change requires a climate-smart transformation and reorientation at multiple scales. Vietnam is one of the developing countries that is agriculture-based and severely affected by climate change; therefore it is crucial that the agricultural system advances toward this transformation. While climate-smart agriculture has gained a significant attention in global fora, context-specific evidence is still scarce in Vietnam. This study examines climate-smart agriculture potentials in tea production systems in the northern mountainous region of Vietnam. Since the climate-smart agriculture concept is multidimensional, which includes food security and adaptation and mitigation, an interdisciplinary analytical framework is employed in this research to assess the economic and biophysical dimensions. Enterprise budgets and representative farms (i.e., farms or households having one or more activities or enterprises) are developed for tea and alternative crops, as well as livestock production, to analyze the productivity dimension of food security. In evaluating the adaptation potential of tea production, local farmers’ perceptions and experiences of extreme weather events are combined with ERA-Interim data (1989-2013) and household survey data on income levels (reanalysis dataset taken from the European Centre for Medium-Range Weather Forecasts; ERA stands for ECMWF Reanalysis). Greenhouse gas emissions and carbon sequestration potentials are estimated through partial Carbon Footprint Life Cycle Assessment. Results show that tea production systems generate net margins, returns to capital, and family labor higher than the alternatives. Farmers, therefore, have high incentives to switch from other crops to tea production. In the face of climate change, tea has shown a strong biophysical adaptive capacity compared to other crops in the northern mountainous region. Tea production systems have a high capability for carbon storage. Evidence of strong synergies between food security and mitigation and adaptation is demonstrated for tea production systems in the northern mountainous region, and potential tradeoffs were highlighted, where relevant.

A simulation of crop choice was performed to examine the feasibility of introducing diversified farming systems, coexisting with seasonal floods, as an alternative to triple rice cropping system in the flood-prone Mekong Delta in Vietnam. A combination of 1.78 to 1.88 ha of double rice cropping and 0.12 to 0.22 ha of upland cropping can achieve an equivalent income or profit from 2 ha of triple rice cropping. Farmers evaluated the full-dike system positively in terms of both economic aspects and living conditions. Some farmers recognized that full flood control might have worsened the natural environment and reduced soil fertility resulting in declining rice yields. To establish a smart flood control system as an adaptation strategy against expected climate change, the following measures must be undertaken: (1) sensitize farmers to the increasing climatic risk in the near future and long-term adverse effects of intensive triple rice cropping; (2) offer alternative environmentally sound and economically profitable farming systems; and (3) develop institutional design for well-coordinated gate and pumping operations both at dike units and in canal network systems.

This article highlights the experiences and lessons generated by the project collaborators in enhancing the adaptive capacities of selected upland farming communities in Southeast Asia. The project collaborators employed capability building programs, such as farmers' and technicians' training, local climate change awareness programs, cross-farm visits, demonstration plots showcasing agroforestry technologies as climate change adaptation (CCA) strategies, and linking science with policies. The outcomes of the project indicate that this program was able to enhance the local adaptive capacities of the upland farming communities by building their key community assets, creating knowledge and information, initiating innovations, strengthening institutions, and initiating forward-looking decision making and governance. The lessons and experiences generated from these initiatives could serve as important reference for scaling up the project. The outputs and outcomes of the capacity development initiatives have generated lessons that could contribute to the body of knowledge in CCA, particularly on enhancing the adaptive capacities for CCA.

Authors: ÖZCAN Ebru , ÖZYER Yasemin
Published: March 2023

Çalışmanın amacı, COVID-19 döneminde çalışan hemşirelerin stres, depresyon, anksiyete düzeyleri ile psikolojik bakım algılarını incelemektir. Tanımlayıcı olarak yapılan çalışma, 224 hemşireyle, demografik soru formu, depresyon anksiyete stres ölçeği kullanılarak gerçekleştirilmiştir. Hemşirelerin %55,8’inin pandemi sürecinde hiçbir ruh sağlığı hizmetini kullanmadığı, %14,8’inin ruh sağlığı hizmeti olarak medya kaynaklarını kullandığı görülmüştür. Hemşirelerden %37,9’unun COVID-19 öncesi döneme göre sağlık durumunu kötü olarak algıladığı, %63,8’inin psikolojik bakım gereksinimlerinin karşılanmadığı, %29,4’ ünün bu süreçte aile ve akrabalarından yardım almak istediği belirlenmiştir. Hemşirelerin orta düzeyde depresyon ve anksiyete, hafif düzeyde stres yaşadıkları saptanmıştır. Çalışmada yaşın stres ve anksiyete ile ilişkili olduğu belirlenmiştir. Çalışmamızda erişilen ruh sağlığı hizmetleri ile depresyon düzeyi arasında ilişki olduğu saptanmıştır. Hemşirelerin pandemi sürecinde kimden yardım almak istedikleri ile depresyon, stres ve anksiyete düzeyleri ile ilişki olduğu belirlenmiştir. Bulgularımız COVID-19 pandemisinin hemşireler üzerinde önemli psikososyal etkilerinin olduğunu ve hemşirelerin psikolojik bakım algılarının olumsuz olduğunu göstermektedir. Sonuç olarak hemşireleri psikolojik olarak desteklemek, özellikle mesleki stres düzeylerinin çok yüksek olduğu durumlarda sağlıklarını koruyabilmek için esastır.
COVID-19 Pandemisi ve Öncesi Dönemde Hastaneye Yatışların Değerlendirilmesi

Published: March 2023

Bu araştırmanın amacı, pandemi dönemi ile pandemi öncesi dönemdeki hastane yatışlarını karşılaştırmak ve hizmet kullanımındaki değişimi tespit etmektir. Araştırma, pandemi öncesi dönem (Mart 2019-Şubat 2020) ile pandemi döneminde (Mart 2020-Şubat 2021) bir eğitim ve araştırma hastanedeki tüm yatışları kapsamaktadır. Araştırma retrospektif ve tanımlayıcı bir araştırma olarak yürütülmüştür. İlgili dönemde araştırma kapsamına giren 60.726 hastaya ilişkin tüm veriler analiz edilmiştir. Pandemi döneminde pandemi öncesi döneme göre hasta yatışında %36,61’lık bir azalma meydana gelmiştir. Hastane yatış sayısının en fazla düştüğü ay Mayıs 2020 (%51,78) iken en az düştüğü ay Ağustos 2020 (%16,45) olmuştur. Hastaların yatış yaptıkları birimler bakımından enfeksiyon hastalıkları ve palyatif bakım hariç tüm alanlardaki yatışlarda düşüş meydana gelmiştir. Enfeksiyon hastalıkları ve klinik mikrobiyoloji biriminde hasta yatışları yaklaşık olarak %500 artarken, genel cerrahide %50, göğüs cerrahisinde %80, kardiyolojide %67 azalmıştır. Yatış sayılarındaki düşüşe karşın ölüm sayıları artmıştır. Hastane yatış süresinde önemli bir değişme olmazken hasta başına düşen fatura tutarı %72’nin üzerinde artmıştır. Pandemi döneminde hastane yatışlarındaki düşüş, sunulması gereken hizmetin aksamasına ve buna bağlı olarak olumsuz hasta sonuçlarına neden olabilir. Pandeminin rutin hastalar üzerindeki olumsuz etkisini azaltmak için karar vericiler tarafından hizmet açıklarına yönelik acil önlemler alınmalıdır.
