A Polymer-Biologic Hybrid Hernia Construct: Review of Data and Early Experiences
Authors: Sawyer Michael , Ferzoco Stephen , DeNoto George
Published: June 2021

Surgical mesh reinforcement of the human abdominal wall has been found to reduce the chance of recurrence in hernia repairs. While traditionally polymer meshes have been used in hernia repair, alternative mesh options have been engineered to prevent the inflammatory foreign body response invoked by polymers. A reinforced tissue matrix (RTM) mesh has been developed by embedding a polymer within a decellularized extracellular matrix. This combination has been attributed to the recruitment of host cells, a pro-healing response, and attenuation of the foreign body response. This has been observed to lead to the regeneration of functional tissue within the repair site that is reinforced by the polymer to offload abdominal pressures over time. This manuscript presents the review of OviTex, an RTM, in several types of hernia repair. The authors have found that the use of RTM in hernia repair is effective in preventing foreign body response, promoting wound healing, and providing reinforcement to lower the risk of hernia recurrence.

Published: June 2021

This work theoretically determined the high-energy photon shielding properties of high-density polyethylene (HDPE) composites containing rare-earth oxides, namely samarium oxide (Sm2O3), europium oxide (Eu2O3), and gadolinium oxide (Gd2O3), for potential use as lead-free X-ray-shielding and gamma-shielding materials using the XCOM software package. The considered properties were the mass attenuation coefficient (µm), linear attenuation coefficient (µ), half value layer (HVL), and lead equivalence (Pbeq) that were investigated at varying photon energies (0.001–5 MeV) and filler contents (0–60 wt.%). The results were in good agreement (less than 2% differences) with other available programs (Phy-X/PSD) and Monte Carlo particle transport simulation code, namely PHITS, which showed that the overall high-energy photon shielding abilities of the composites considerably increased with increasing rare-earth oxide contents but reduced with increasing photon energies. In particular, the Gd2O3/HDPE composites had the highest µm values at photon energies of 0.1, 0.5, and 5 MeV, due to having the highest atomic number (Z). Furthermore, the Pbeq determination of the composites within the X-ray energy ranges indicated that the 10 mm thick samples with filler contents of 40 wt.% and 50 wt.% had Pbeq values greater than the minimum requirements for shielding materials used in general diagnostic X-ray rooms and computerized tomography rooms, which required Pbeq values of at least 1.0 and 1.5 mmPb, respectively. In addition, the comparisons of µm, µ, and HVL among the rare-earth oxide/HDPE composites investigated in this work and other lead-free X-ray shielding composites revealed that the materials developed in this work exhibited comparable X-ray shielding properties in comparison with that of the latter, implying great potential to be used as effective X-ray shielding materials in actual applications.

This work reports the self-organization of dimple nanostructures on a polyethylene naphthalate (PEN) surface where an Ar ion beam was irradiated at an ion energy of 600 eV. The peak-to-peak roughness and diameter of dimple nanostructures were 29.1~53.4 nm and 63.4~77.6 nm, respectively. The electron energy loss spectrum at the peaks and troughs of dimples showed similar C=C, C=O, and O=CH bonding statuses. In addition, wide-angle X-ray scattering showed that Ar ion beam irradiation did not induce crystallization of the PEN surface. That meant that the self-organization on the PEN surface could be due to the ion-induced surface instability of the amorphous layer and not due to the partial crystallinity differences of the peaks and valleys. A nonlinear continuum model described surface instability due to Ar ion-induced sputtering. The Kuramoto–Sivashinsky model reproduced the dimple morphologies numerically, which was similar to the experimentally observed dimple patterns. This preliminary validation showed the possibility that the continuum equation used for metal and semiconductor surfaces could be applied to polymer surfaces where ion beam sputtering occurred.
Temperature Influence on PI/Si3N4 Nanocomposite Dielectric Properties: A Multiscale Approach
Authors: Houssat Mohammed , Villeneuve-Faure Christina , Lahoud Dignat Nadine , Locatelli Marie-Laure , Cambronne Jean-Pascal
Published: June 2021

The interphase area appears to have a great impact on nanocomposite (NC) dielectric properties. However, the underlying mechanisms are still poorly understood, mainly because the interphase properties remain unknown. This is even more true if the temperature increases. In this study, a multiscale characterization of polyimide/silicon nitride (PI/Si3N4) NC dielectric properties is performed at various temperatures. Using a nanomechanical characterization approach, the interphase width was estimated to be 30 ± 2 nm and 42 ± 3 nm for untreated and silane-treated nanoparticles, respectively. At room temperature, the interphase dielectric permittivity is lower than that of the matrix. It increases with the temperature, and at 150 °C, the interphase and matrix permittivities reach the same value. At the macroscale, an improvement of the dielectric breakdown is observed at high temperature (by a factor of 2 at 300 °C) for NC compared to neat PI. The comparison between nano- and macro-scale measurements leads to the understanding of a strong correlation between interphase properties and NC ones. Indeed, the NC macroscopic dielectric permittivity is well reproduced from nanoscale permittivity results using mixing laws. Finally, a strong correlation between the interphase dielectric permittivity and NC breakdown strength is observed.
Something Distinct, or Business as Usual? Interpreting the Plan of the Late Medieval Bridgettine Monastery in Naantali, Finland
Authors: Immonen Visa , Harjula Janne
Published: June 2021

This article analyses modern interpretations of the medieval plan of the Bridgettine Monastery of Naantali, Finland. Instead of seeing the distinct spatial organisation as deviation from the Bridgettine norm, we consider it as an expression of a medieval process, by which monastic principles were re-conceptualised in order to be realised in material form. This perspective builds on the shift in thinking that has taken place in the study of medieval urban planning. Instead of being ‘organic’, meaning disorganised, medieval urban development has come to be considered as intentional, guided by general principles, although not in a manner that is always obvious to the modern mind. We concur that models such as St Bridget’s visions and the plan of Vadstena Abbey are important tools for reconstructing medieval monastic plans. Meanwhile, we propose that such models can also add latent and counterproductive baggage to this field of study by encouraging modern expectations of regularity within monastic architecture. If the designs of monasteries do not follow such models perfectly, discrepancies are often erroneously misconceived as indications of the builders’ insufficient skills and knowledge.
Heart Rate Variability in Psychology: A Review of HRV Indices and an Analysis Tutorial
Authors: Pham Tam , Lau Zen Juen , Chen S. H. Annabel , Makowski Dominique
Published: June 2021

The use of heart rate variability (HRV) in research has been greatly popularized over the past decades due to the ease and affordability of HRV collection, coupled with its clinical relevance and significant relationships with psychophysiological constructs and psychopathological disorders. Despite the wide use of electrocardiograms (ECG) in research and advancements in sensor technology, the analytical approach and steps applied to obtain HRV measures can be seen as complex. Thus, this poses a challenge to users who may not have the adequate background knowledge to obtain the HRV indices reliably. To maximize the impact of HRV-related research and its reproducibility, parallel advances in users’ understanding of the indices and the standardization of analysis pipelines in its utility will be crucial. This paper addresses this gap and aims to provide an overview of the most up-to-date and commonly used HRV indices, as well as common research areas in which these indices have proven to be very useful, particularly in psychology. In addition, we also provide a step-by-step guide on how to perform HRV analysis using an integrative neurophysiological toolkit, NeuroKit2.

The Cost of Reducing Municipal Unsorted Solid Waste: Evidence from Municipalities in Chile
Authors: Molinos-Senante Maria , Maziotis Alexandros
Published: June 2021

The management of municipal solid waste sector is crucial for a sustainable circular economy. Waste utilities are expected to provide high quality solid waste services at an affordable price. The efficient management of solid waste requires its assessment from an economic and environmental perspective, i.e., eco-efficiency assessment. Although the reduction of unsorted waste incurs an economic cost, its positive externalities are huge for the well-being of society, the environment, and people. Our study quantifies the marginal cost of reducing any unsorted waste using stochastic frontier analysis techniques which allow us to estimate the eco-efficiency of the waste sector. Our empirical approach focuses on the municipal solid waste collection and recycling services provided by several waste utilities in Chile. The results indicate that substantial eco-inefficiency in the sector exists, since the average eco-efficiency score is roughly 0.5 which means that the municipalities could approximately halve their operational costs and unsorted waste to produce the same level of output. The average marginal cost of reducing unsorted waste is 32.28 Chilean pesos per ton, although notable differences are revealed among the waste utilities evaluated. The results provided by this study are of great interest to stakeholders to promote sustainable management solutions and resource efficient solid waste services.
Should There Be Industrial Agglomeration in Sustainable Cities?: A Perspective Based on Haze Pollution
Authors: Dai Pingping , Lin Yuanyuan
Published: June 2021

Haze pollution is a problem that cannot be ignored in the process of building sustainable cities, and while shifting industrial enterprises can solve the problem at the root, it is not conducive to the sustainable development of urban economies. This paper discusses the role of industrial agglomeration on urban pollution amelioration (haze pollution) using a sample of 253 prefecture-level cities in China. The highlight of this paper is the study of economic and environmental factors in the development of sustainable cities in the same framework and a series of econometric treatments that greatly increase the accuracy of the empirical evidence. Research intuitively shows that China’s haze pollution is clustered in spatial distribution and is spatially heterogeneous in concentration. With the passage of time, haze pollution has a tendency to move from an H–H concentration area to an L–L concentration area. The regression results show that an increase in the scale of local industrial agglomeration will lead to a decrease in local haze pollution; but an increase in the scale of local industrial agglomeration will lead to an increase in haze pollution in adjacent areas. Industrial agglomeration has significant spatial spillover effects, which are spatially heterogeneous. In addition, spillover effects between regions are greater than those within regions. After replacing the spatial weight matrix and controlling the endogenous problem using the instrumental variable method, the conclusion is still robust.
Assessment of Nitrogen Flows at Farm and Regional Level When Developing the Manure Management System for Large-Scale Livestock Enterprises in North-West Russia
Authors: Briukhanov Aleksandr , Vasilev Eduard , Kozlova Natalia , Shalavina Ekaterina
Published: June 2021

Arranging efficient manure management is the major environmental challenge in livestock farming in the Leningrad Region, with manure nitrogen being regarded as the main pollution source. The study aimed to identify the baselines for taking integrated manure management decisions towards reducing nitrogen losses applying nitrogen surplus and nitrogen use efficiency (NUE) as indicators calculated at the regional and municipal district level. At the regional level, NUE was found to be 34% and N surplus was 103 kg ha−1. Eleven “environmentally friendly” districts had a mean NUE of 59%, a mean N surplus 39.6 kg ha−1 and a mean animal density 0.89 LSU ha−1. Four districts were identified as “hot spots”, with an animal density in the range from 2.6 to 67 LSU ha−1, NUE from 1 to 37% and N surplus from 87 to 3082 kg ha−1. A scenario was suggested for the redistribution of organic fertilisers between “hot spots” and “environmentally friendly” districts, allowing each district to increase the N surplus to the regional value. Nitrogen flows and measures improving NUE at the farm level through organisational activity and advanced practices were considered with the help of the “N input − N output” diagram and the example of the nitrogen flows on a pilot dairy farm.

Published: June 2021

Gallid alpha-herpesvirus 1, also known as avian infectious laryngotracheitis virus (ILTV), continues to cause huge economic losses to the poultry industry worldwide. Similar to that of other herpesvirus-encoded proteins, the expression of viral genes encoded by ILTV is regulated by a cascade, and the underlying regulatory mechanism remains largely unclear. The viral immediate-early (IE) gene ICP4 plays a prominent role in the initiation of the transcription of early and late genes during ILTV replication. In this study, we identified AP-1 as the key regulator of the transcription of ILTV genes by bioinformatics analysis of genome-wide transcriptome data. Subsequent functional studies of the key members of the AP-1 family revealed that Fos, but not Jun, regulates ILTV infection through AP-1 since knockdown of Fos, but not Jun, by gene silencing significantly reduced ICP4 transcription and subsequent viral genome replication and virion production. Using several approaches, we identified ICP4 as a bona fide target gene of Fos that regulated Fos and has Fos response elements within its promoter. Neither the physical binding of Jun to the promoter of ICP4 nor the transcriptional activity of Jun was observed. In addition, knockdown of Fos reduced the transcription of MDH1 and ATP5A1, genes encoding two host rate-limiting enzymes essential for the production of the TCA intermediates OAA and ATP. The biological significance of the transcriptional regulation of MDH1 and ATP5A1 by Fos in ILTV infection was supported by the fact that anaplerosis of OAA and ATP rescued both ICP4 transcription and virion production in infected cells under when Fos was silenced. Our study identified the transcription factor Fos as a key regulator of ILTV infection through its transcription factor function on both the virus and host sides, improving the current understanding of both avian herpesvirus–host interactions and the roles of AP-1 in viral infection.

Three prophylactic vaccines are approved to protect against HPV infections. These vaccines are highly immunogenic. The most recent HPV vaccine, Gardasil-9, protects against HPV types associated with ~90% of cervical cancer (worldwide). Thus, ~10% of HPV-associated cancers are not protected by Gardasil-9. Although this is not a large percentage overall, the HPV types associated with 10% of cervical cancer not protected by the current vaccine are significantly important, especially in HIV/AIDS patients who are infected with multiple HPV types. To broaden the spectrum of protection against HPV infections, we developed mixed MS2-L2 VLPs (MS2-31L2/16L2 VLPs and MS2-consL2 (69-86) VLPs) in a previous study. Immunization with the VLPs neutralized/protected mice against infection with eleven high-risk HPV types associated with ~95% of cervical cancer and against one low-risk HPV type associated with ~36% of genital warts & up to 32% of recurrent respiratory papillomatosis. Here, we report that the mixed MS2-L2 VLPs can protect mice from three additional HPV types: HPV51, which is associated with ~0.8% of cervical cancer; HPV6, which is associated with up to 60% of genital warts; HPV5, which is associated with skin cancers in patients with epidermodysplasia verruciformis (EV). Overall, mixed MS2-L2 VLPs can protect against twelve HPV types associated with ~95.8% of cervical cancers and against two HPV types associated with ~90% of genital warts and >90% recurrent respiratory papillomatosis. Additionally, the VLPs protect against one of two HPV types associated with ~90% of HPV-associated skin cancers in patients with EV. More importantly, we observed that mixed MS2-L2 VLPs elicit protective antibodies that last over 9 months. Furthermore, a spray-freeze-dried formulation of the VLPs is stable, immunogenic, and protective at room temperature and 37 °C.

It is suggested that HPV-18 variants from the A lineage have higher oncogenic potential compared to B variants. Some studies show uneven distribution of HPV-18 variants in cervical adenocarcinomas and squamous cell carcinomas. Regarding HPV-18 variants’ functions, the few studies reported focus on E6, and none were performed using natural host cells. Here, we immortalized primary human keratinocytes (PHKs) with E6/E7 of HPV-18 A1 and B1 sublineages and functionally characterized these cells. PHK18A1 reached immortalization significantly faster than PHK18B1 and formed a higher number of colonies in monolayer and 3D cultures. Moreover, PHK18A1 showed greater invasion ability and higher resistance to apoptosis induced by actinomycin-D. Nevertheless, no differences were observed regarding morphology, proliferation after immortalization, migration, or epithelial development in raft cultures. Noteworthy, our study highlights qualitative differences among HPV-18 A1 and B1 immortalized PHKs: in contrast to PHK18A1, which formed more compact colonies and spheroids of firmly grouped cells and tended to invade and migrate as clustered cells, morphologically, PHK18B1 colonies and spheroids were looser, and migration and invasion of single cells were observed. Although these observations may be relevant for the association of these variants with cervical cancer of different histological subtypes, further studies are warranted to elucidate the mechanisms behind these findings.
TiO2-Powdered Activated Carbon (TiO2/PAC) for Removal and Photocatalytic Properties of 2-Methylisoborneol (2-MIB) in Water

Published: June 2021

2-methylisoborneol (2-MIB) is a common taste and odor compound caused by off-flavor secondary metabolites, which represents one of the greatest challenges for drinking water utilities worldwide. A TiO2-coated activated carbon (TiO2/PAC) has been synthesized using the sol-gel method. A new TiO2/PAC photocatalyst has been successfully employed in photodegradation of 2-MIB under UV light irradiation. In addition, the combined results of XRD, SEM-EDX, FTIR and UV-Vis suggested that the nano-TiO2 had been successfully loaded on the surface of PAC. Experimental results of 2-MIB removal indicated that the adsorption capacities of PAC for 2-MIB were higher than that of TiO2/PAC. However, in the natural organic matter (NOM) bearing water, the removal efficiency of 2-MIB by TiO2/PAC and PAC were 97.8% and 65.4%, respectively, under UV light irradiation. Moreover, it was shown that the presence of NOMs had a distinct effect on the removal of MIB by TiO2/PAC and PAC. In addition, a simplified equivalent background compound (SEBC) model could not only be used to describe the competitive adsorption of MIB and NOM, but also represent the photocatalytic process. In comparison to other related studies, there are a few novel composite photocatalysts that could efficiently and rapidly remove MIB by the combination of adsorption and photocatalysis.

Excessive ingestion of fluoride through the consumption of F−-rich drinking water could cause adverse effects to human health. For this reason, the WHO has fixed 1.5 mg/L as the maximum F- concentration for drinking water. In this work, a detailed geochemical characterization was performed to define the source of natural pollution of two groundwaters (samples Pc and Bg) coming from deep crystalline aquifers located in the Calabria region (southern Italy) and to define and optimize the most appropriate water treatment strategy. The samples were classified as a F− enriched NaHCO3 type of water. In particular, the F− concentrations observed were 30 mg/L and 8.9 mg/L for the Pc and Bg samples, respectively. Based on the acquired geochemical characterization knowledge, the groundwaters were treated by two thin-film composite NF membranes, namely SPR 10113 and SPR 10114 which have so far not been used for water defluoridation. It was found that the SPR 10114 membrane was able to guarantee water permeates with F− contents lower than the threshold value of 1.5 mg/L for both treated waters, whereas the fluoride content remained above the threshold value when the Pc sample was treated using the SPR 10113 membrane. The obtained permeates were characterized by a low ionic load and were not suitable for long-term consumption as drinking water. However, all of the produced waters did not need any further re-mineralizing processes for agricultural irrigation or other purposes.
Cages’ farming foundation as a limiting factor in cultivation of sturgeon fish hybrids

Published: June 2021

The work experimentally confirmed the negative influence of fouling of cage structures on the growth and survival rates of reared young sturgeon hybrid — bester (Huso (Linnaeus, 1758) × Acipenser ruthenus (Linnaeus, 1758)). A significant decrease in growth and an increase in fish mortality in modules with a maximum biofouling area was noted. The possibility of using alternative cleaning methods in comparison with traditional mechanical and chemical ones has been investigated. The positive results of the experimental approbation of the author’s development — the practical application of a specially designed structure made of tarpaulin for the cage are given. The use of an easy-to-manufacture and operate device prevented active contamination of the cells, increased the efficiency of keeping fish, which is economically beneficial for commercial sturgeon growing in cages. In general, in fish farms located in a natural reservoir in the spring-summer period, the overgrowth of fodder bottoms and cage walls with filamentous algae has a strong negative effect on the cultivation of sturgeon fish. To optimize the fish-breeding process and reduce the number of algae during the period of their active growth on cages (the timing must be determined according to the conditions of a particular reservoir), special canvas covers should be used. This device will reduce the amount of sunlight entering the cage bottoms and slow down the growth of filamentous algae. To install this device on the cage, two workers are required, the approximate installation time (and, if necessary, dismantling) will be 20 minutes. To reduce the negative effect of algae fouling of the cage bed, measures should be taken to mechanically clean the stern bottoms and walls of the cage with high-pressure cleaning (washer) devices, after transplanting the cultivated objects into another fish hatchery
The development of method of hormonal stimulation of N.L.Gerbilsky and appearance of contemporary preparations of long-term storage
Authors: Trenkler Igor Vladimirovich
Published: June 2021

The The main discovery of the 20th century in the field of fish breeding is hormonal stimulation of final stages of maturation of fish at hatcheries. The «father» of method of pituitary injections was Leningrad ichthyologist N.L. Gerbilsky. The main achievements of N.L. Gerbilsky and his school are methods of mass extraction of fish pituitaries, their dehydration by acetone for later storage and use, testing of pituitary gonadotropic activity on different objects. The induction of ovulation in female loaches Misgurnus fossilis or spermiation reaction of Galli-Mainini in male frogs Rana ridibunda or R. temporaria were used for pituitary testing. The effective doses of dried pituitaries for sturgeons were determined in milligrams and loach units or frog units. The method of pituitary injections was used for functioning of sturgeon breeding facilities at Volga, Don, Kuban and Kura and other rivers. For guaranteed answer fish breeders used hyperdoses of dry pituitary powder because its gonadotropic activity varied in dependence on stage of maturity of fish-“donors”. The followers of N.L. Gerbilsky led by Prof. I.A. Barannikova developed the technique of production of special glycerol pituitary extract (GPE) with determined gonadotropic activity. The main role in formulation of the recipe of GPE belongs to A.A. Boyev. The use of GPE has removed the problem of hyperdosing leading to worsening quality of mature germinal cells of sturgeons. Later, A.A. Boyev on the basis of this recipe with replacement of glycerol to propylene glycol created stabilizing solution of analogue of mammal LH-RH (“surphagon”) of long-term storage with concentration of active substance from 20 to 500 micrograms/ml.

Published: June 2021

Regional-scale shoreline and beach volume changes are quantified using the Joint Airborne Lidar Bathymetry Technical Center of Expertise’s digital elevation model products in a change detection framework following the passage of the two landfalling hurricanes, Hurricanes Sally and Zeta, along the northern Gulf Coast in late fall 2020. Results derived from this work include elevation change raster products and a standard set of beach volume and shoreline change metrics. The rapid turn-around and delivery of data products to include volume and shoreline change assessments provide valuable information about the status of the coastline and identification of areas of significant erosion or other impacts, such as breaching near Perdido Key, FL, from Hurricane Sally’s impact. These advanced change detection products help inform sediment budget development and support decisions related to regional sediment management and coastal storm risk management.
Water resources management – towards performance based approach.
Authors:   Slobodan P. Simonovic
Published: June 2021

Global change that results from population growth, global warming, and land use change (especially rapid urbanization) directly affects the complexity of water resources management problems and the uncertainty they are exposed to. Both, the complexity and the uncertainty, are the result of dynamic interactions of innumerable system parts within three major systems: (i) the physical environment; (ii) the social and demographic characteristics of the region under consideration; and (iii) the pipes, roads, bridges, buildings, and other components of the constructed environment (infrastructure). Recent trends in dealing with complex water resources systems include consideration of the entire region being affected, explicit consideration of all costs and benefits, elaboration of a large number of alternative solutions, and the greater participation of all stakeholders in the decision-making. Systems approaches based on simulation, optimization, and multi-objective analyses, in deterministic, stochastic and fuzzy forms, demonstrated in the last 50 years, an excellent potential for providing appropriate support for effective water resources management. This paper explores the future opportunities based on the advances in systems theory that can, on a broader scale, majorly transform the management of water resources. The paper identifies performance-based water resources engineering as a methodological framework to improve water resources management in the face of rapid climate destabilization so that sustainability becomes the norm, not the occasional success story.

Intertext and Allusion in the Qur’anic Presentation of Noah’s Story
Authors: Abdullah Abdul-Samad
Published: June 2021

This study explores the Qur’anic presentation of the story of Noah and his people. In particular, it examines the purposes behind the variations and similarities found in the s´rahs that mention it and focuses on three fundamental aspects: linguistic or stylistic variations, religious or moral purposes that determine a particular linguistic or stylistic register and contextualize the story within a particular s´rah, and the extent to which the style serves that s´rah’s objectives. Moreover, while this story has very clear and consistent themes, each s´rah’s concern and context to some extent shapes its rendering therein. Hence, I propose that the repetition of this story is a response to a particular context or conforms to the particular aims and objectives of the s´rah in which it appears. This repetition or intertext and allusion therefore become desirable, if not necessary, for both religious and stylistic requirements.
Black Muslim Theology and the Classical Islamic Tradition
Authors: Williams Wesley
Published: June 2021

Elijah Muhammad declared unapologetically that “God is aman.” This anthropomorphist doctrine does violence to modern normative Islamic articulations of tawú¥d (monotheism), the articulations of which involve God’s “otherness” from the created world. The Nation of Islam (NOI), therefore, has been the target of polemics from Muslim leaders who, from within and without the United States, have declared its irredeemable heterodoxy. But in premodern Islam, heresy was in the eye of the beholder and “orthodoxy” was a precarious and shifting paradigm. This paper attempts to, in the words of Zafar Ishaq Ansari, “examine how the ‘Nation of Islam’ fits into the framework of Islamic heresiology.”

Pendahuluan Pandemi covid 19 mulai memberikan dampak secara global, sehingga hampir semua negara harus menghadapi krisis kesehatan dan social ekonomi yang parah, bahkan belum pernah terjadi sebelumnya. Aktifitas kehidupan anak dan keluarga seakan terhenti, tak terkecuali, negara Indonesia turut merasakan hal ini. Penyakit yang dimunculkan akibat infeksi covid 19 dapat menyerang siapa saja. Hingga saat ini tercatat ada 145 anak meninggal dunia akibat virus corona baru atau COVID-19 di Indonesia, jauh lebih tinggi dibanding negara-negara lain (Ainun Najib, 2020). Negara Indonesia memegang rekor tertinggi dalam hal tingkat kematian anak di Asia Pasifik akibat covid 19  dengan rata-rata sebesar 2,5% (IDAI, 2020). Guna mendukung upaya yang telah digalakkan oleh pemerintah, maka peran unit terkecil yaitu keluarga sangatlah penting. Kendali kehidupan anak-anak terletak pada tingkat ketrampilan orangtua dalam menerapkan pola asuh yang memadai. Pada masa pandemic covid 19 saat ini, perilaku orangtua dalam hal kesehatan sangat dibutuhkan. Tujuan penelitian ini untuk mencari gambaran bagaimana perilaku orangtua dalam upaya pencegahan covid 19 pada anak. Metode penelitian menggunakan deskripsi observasional, dengan populasi semua orangtua yang memiliki anak usia 1-12 tahun. Sampel penelitian diambil dengan menggunakan accidental sampling. Hasil penelitian, ditunjukkan uji spearman rank didapatkan koefisien korelasi sebesar 0,447 dan p value sebesar 0,054 (α<0,05). Kesimpulan  ada hubungan antara perilaku orang tua terhadap pencegahan covid-19 dengan usia anak  dengan tingkat hubungan yang cukup kuat (r=0,047) dan berpola positif, dimana makin bertambah usia anak, maka akan meningkatkan perilaku orang tua terhadap covid-19. Saran dalam penelitian selanjutnya untuk mengembangkan variable penelitian ini dengan cakupan responden yang lebih banyak dan analisis yang lebih akurat.

Társadalmi innovációs lehetőségek a turizmusban
Authors: Nagy Katalin
Published: June 2021

A társadalmi innováció nem más, mint új megoldások kidolgozása és megvalósítása társadalmi problémák megoldása érdekében. A legtöbb magyar és nemzetközi szakirodalom a társadalmi marketinget és más, területfejlesztési megközelítéseket dolgoz fel, s csak ritkán vizsgálja a jelenséget a turizmussal kapcsolatban. Számos kutatás vizsgálódik a kérdéskörben a vállalkozások szemszögéből (pl. Howards-Grenville et al 2014, Schrempf 2014), intézményi oldalról (pl. Dorado 2013, Zietsma és Lawrence 2010), vagy menedzsment, CSR és interszektorális partnerségi viszonyban (pl. De Bakker et al 2005). Mindemellett, találunk társadalmi innovációs jó gyakorlatot a turizmusban is, pl. a tematikus utak terén (pl. Lourens 2007). Jelen tanulmány a szakirodalmi áttekintés mellett a társadalmi innovációk turisztikai alkalmazási lehetőségeit veszi számba, bemutatva néhány jó gyakorlatot, eredményes példát, majd néhány hazai alkalmazási lehetőségre mutat rá a tematikus turizmusfejlesztés területéről.

Novel Distributed and Federated Contact Tracing Systems – A Global Solution
Authors: T S Narayanan Hari
Published: June 2021

There are several contact tracing solutions, some are for closed user groups, some are for the residents of a country, and some are open solutions with no clear boundary defined. These independent solutions are not adequate to support pre-pandemic global mobility. Ideally, what is needed is a global solution that can support decentralized control over data and at the same time support proximity data exchange among Apps developed by different vendors and for different countries. This paper proposes a family of contact tracing designs with low-risk anonymity that includes a centralized design, a distributed design, and a federated design for global solution.

Background:

Population of people with diabetes mellitus (DM) are increasing every year. As a chronic illness, patients with DM needs to practice self-management for life. Adopted the nursing system in other countries that are more advanced in DM care, however the study is still under investigation.

Objectives: Primary objective was to analyze the diabetic Self-management among the Indonesian and Taiwan population in Hospital. Secondary was to develop theory-guided and/or evidence-based nursing model in the self-management among diabetic patient with practical issues.

Methods: We used a case study design by discussion across the multi-discipline of health care provider point of view, observation and brief interview session with patient, observe the health care model, learning process of health education between nurse and patient and whole application of the health education, at Veteran Hospital in Taiwan and Manambai Abdulkadir Hospitals in Indonesia.

Results: Education system related to self-management of DM patients have been running and prepared by the Veteran hospital in Taiwan. The health system for diabetes management was called by diabetes shared care. Nurse, nutritionist and doctor have similar opinions about self-management in DM patients in Taiwan but different perspective among health professionals in Indonesia. The process of applying of evidence-based nursing practice and guidelines for providing health education to patients in Veteran Hospital Taiwan was using guidelines from the diabetes federation of China (Taiwan), on the other hand, standard operating procedure in Hospital in Manambai Abdulkadir Hospital, Indonesia, it is due to different policy in each country.

Conclusion: The model of self-management might can be successfully be applied in clinical setting with several strategies by resolve the challenges. Hopefully, this study can be providing valuable information to the health professionals in order to provide the best service for patients with DM.

ANALYSIS OF DETERMINANT FACTORS OF AFFECTING FAMILY ABILITY IN HIGH-RISK PREGNANCY
Authors: Mardiyanti Ika , Anggasari Yasi
Published: June 2021

Background: The ability of pregnant women to deal with early response to high risks is still below the average, which is one of the causes of complications that can indicate the welfare of the mother and her fetus.

Objectives: The aim of this study was to look at the determinants that influence early detection of high-risk pregnancies.

Methods: This study used an analytic design with a cross sectional design. The sample size of 112 from a population of 155 was obtained by simple random sampling. The independent variables are individual factors, interpersonal influence, filial value and commitment, while the dependent variable is the family's ability to detect high risk of pregnancy for 3 months, namely August-October 2020 at PMB Ika Mardiyanti. This study uses a questionnaire. Data collection in the form of a questionnaire. Data analysis using SEM-PLS.

Results: The results of the significance test concluded that all the path coefficients and the T statistical value of personal factors on interpersonal (0.453; 6.612), interpersonal on filial values ​​(0.753; 7.267), filial value for commitment (0.851; 17.048), filial value for ability (0.667 ; 4,679), commitment to ability (0.358; 2.356) is significant. Because all have a T-statistic value that is more than the T-table 1.96.

Conclusion: The determinant factors that contribute to the ability of families to detect high risk of pregnancy need to be considered so that families are independent and have efforts to maintain the health of pregnant women in their families. In further research, it is necessary to involve other factors to improve family capacity, especially in the ability of families to detect high-risk pregnancies early.

Проведено дослідження щодо санітарної обробки приміщення для утримання собак різними дезінфектантами. Показано перспективність озонових технологій для дезінфекції павільйону.

Санітарна обробка вольєру здійснювалась за допомогою гарячого розчину «Хлорантоін» (дезінфекційний засіб з миючим ефектом ). При оцінці початкового санітарного стану приміщення для утримання собак установлено, що забрудненість майже всіх ділянок перевищувала допустиму норму.

Доведено, що озоно-повітряна суміш є ефективним способом знезараження приміщення та дезінфекції повітря, ступінь якого залежить від концентрації озону і тривалості експозиції. Після обробки ОПС з концентрацією озону 15-20 мг/м3, і тривалістю експозиції 30 хв. повністю знищуються пліснява, дріжджі, мезофільні аеробні і факультативно анаеробні мікроорганізми.

При обробці підлоги ОПС з концентрації озону 15-20 мг/м3 тривалість експозиції не чинила суттєвого впливу на якість дезінфекції. Як кількість плісняви та дріжджів так і кількість мезофільних аеробних і факультативно анаеробних мікроорганізмів у дослідних зразках змивів підлоги зменшилася на 99,99 % (р ≤ 0,01) у порівнянні з контрольними зразками.

При порівнянні обробки вольєру хлорвмісними засобами та озоно-повітряною сумішшю, було встановлено, що одна з основних неприємних властивостей хлору полягала в тому, що при його реакції з більшістю органічних сполук виникав цілий спектр хлорорганічних похідних, більшість із яких дуже отруйні, причому дія цих токсинів полягає в руйнуванні імунної системи як людини так і тварини.

O cultivo de ostras em Santa Catarina se desenvolveu muito ao longo das duas últimas décadas e passou a ser uma atividade sócio-econômica importante devido às condições climáticas e à própria característica do litoral catarinense. Atualmente um dos fatores mais preocupantes para a expansão da atividade no Estado é o aparecimento de predadores. O presente estudo teve como objetivo analisar a interação do predador Cymatium parthenopeum (Von Salis, 1793) com a ostra Crassostrea gigas (Thunberg, 1795) em cultivo comercial na localidade do Ribeirão da Ilha, Florianópolis, Santa Catarina. A metodologia utilizada foi o recolhimento manual dos espécimes de Cymatium parthenopeum presentes nas lanternas de ostras quando de seu manejo periódico. Verificou-se a presença de espécimes de predador no período compreendido entre novembro de 2007 e março de 2008, totalizando 1234 exemplares coletados. Além desta espécie, foram encontradas as espécies Cymatium cingulatum (Lamarck, 1822) e Thais haemastoma (Linnaeus, 1767). Também foram observadas ootecas fixadas em conchas de ostras. Verificou-se que nos períodos de maior incidência do predador, a taxa de mortalidade das ostras ficou acima da taxa normal esperada.
