The low-power sensing platform proposed by the Convergence project is foreseen as a wireless, low-power and multifunctional wearable system empowered by energy-efficient technologies. This will allow meeting the strict demands of life-style and healthcare applications in terms of autonomy for quasi-continuous collection of data for early-detection strategies. The system is compatible with different kinds of sensors, able to monitor not only health indicators of individual person (physical activity, core body temperature and biomarkers) but also the environment with chemical composition of the ambient air (NOx, COx, NHx particles) returning meaningful information on his/her exposure to dangerous (safety) or pollutant agents. In this article, we introduce the specifications and the design of the low-power sensing platform and the different sensors developed in the project, with a particular focus on pollutant sensing capabilities and specifically on NO2 sensor based on graphene and CO sensor based on polyaniline ink.
A Conceptual Model of Measurement Uncertainty in IoT Sensor Networks
Authors: Cofta Piotr , Karatzas Kostas , Orłowski Cezary
Published: March 2021

The growing popularity of inexpensive IoT (Internet of Things) sensor networks makes their uncertainty an important aspect of their adoption. The uncertainty determines their fitness for purpose, their perceived quality and the usefulness of information they provide. Nevertheless, neither the theory nor the industrial practice of uncertainty offer a coherent answer on how to address uncertainty of networks of this type and their components. The primary objective of this paper is to facilitate the discussion of what progress should be made regarding the theory and the practice of uncertainty of IoT sensor networks to satisfy current needs. This paper provides a structured overview of uncertainty, specifically focusing on IoT sensor networks. It positions IoT sensor networks as contrasted with professional measurement and control networks and presents their conceptual sociotechnical reference model. The reference model advises on the taxonomy of uncertainty proposed in this paper that demonstrates semantic differences between various views on uncertainty. This model also allows for identifying key challenges that should be addressed to improve the theory and practice of uncertainty in IoT sensor networks.

Authors: Yu Jing , Jiang Wensong , Luo Zai , Yang Li
Published: March 2021

In this paper, we propose a Circular-ring visual location marker based on a global image-matching model to improve the positioning ability in the fiducial marker system of a single-target mobile robot. The unique coding information is designed according to the cross-ratio invariance of the projective theorem. To verify the accuracy of full 6D pose estimation using the Circular-ring marker, a 6 degree of freedom (DoF) robotic arm platform is used to design a visual location experiment. The experimental result shows in terms of small resolution images, different size markers, and long-distance tests that our proposed robot positioning method significantly outperforms AprilTag, ArUco, and Checkerboard. Furthermore, through a repeatable robot positioning experiment, the results indicated that the proposed Circular-ring marker is twice as accurate as the fiducial marker at 2–4 m. In terms of recognition speed, the Circular-ring marker processes a frame within 0.077 s. When the Circular-ring marker is used for robot positioning at 2–4 m, the maximum average translation error of the Circular-ring marker is 2.19, 3.04, and 9.44 mm. The maximum average rotation error is also 1.703°, 1.468°, and 0.782°.
Driving with Hemianopia VIII: Effects of a Vibro-Tactile Assistance System on Safety and Gaze Behavior in Pedestrian Crossing Situations
Authors: Hölzl Roman , Steckhan Lorenz , Lehsing Christian , Savage Steven W. , Bowers Alex R.
Published: March 2021

People with homonymous visual field defects (HVFDs), the loss of vision in the same half of the visual field in both eyes, are permitted to drive in some jurisdictions. However, the HVFD may cause difficulties in detecting hazards approaching on the side of the field loss (the blind side). An advanced driver assistance system (ADAS) could assist with hazard detection, but little research has been conducted to evaluate the potential benefits of an ADAS for visually impaired drivers. We developed a prototype vibro-tactile assistance system for drivers with HVFDs and conducted a proof-of-concept driving simulation study to evaluate the system. Given that pedestrian accidents are the second most frequent cause of death in road traffic and most of those accidents occur in urban scenarios, we evaluated the potential of the assistance system to improve responses to pedestrian hazards in a city environment. Sixteen participants, of which eight had HVFDs and eight had normal vision, took part. Our analyses evaluated the effects of the driver assistance system, crossing direction, and pedestrian behavior on the safety of pedestrian events and the participant’s gaze behavior at each of the 256 crossing situations. Generalized linear mixed effects models were used to assess binomial outcome variables. Despite the limited sample size, the results suggest that the vibro-tactile directional warnings were effective in directing the drivers’ gaze so that they were looking in the necessary direction before a potential hazard occurred. More time was spent fixating pedestrians on the blind side when the ADAS was engaged, and as a result, the safety of street crossings from the blind side improved. The effect of the ADAS was greater on responses to pedestrians from the blind than the seeing side. With an activated ADAS, crossings from the participants’ blind sides were as safe as crossings from their seeing sides, and it was as safe as the crossings when normally sighted participants were driving. The results suggest that the vibro-tactile ADAS is a promising approach to improve the safety of drivers with HVFD and surrounding traffic.
A Spatial Ecosystem Services Assessment to Support Decision and Policy Making: The Case of the City of Bologna
Authors: Vignoli Francesca , de Luca Claudia , Tondelli Simona
Published: March 2021

In recent years, both mapping and assessing urban Ecosystem Services (ESs) to support urban planning has been a topic of great debate. This work aims at contributing to this discussion by developing and testing a methodological approach to first assess and map supply and demand of ESs, and then identify areas of priority of intervention. Starting from the existing models, the work develops a tailored approach to map and assess three ESs (water retention and runoff, PM10 removal, and carbon sequestration and storage) that are tested in the city of Bologna and tailored according to available open data. All data are processed in a GIS environment to allow for spatial distribution and visualization of ESs. These maps facilitate defining supply and demands and, consequently, the presence and distribution of ESs deficiencies. Building on mismatches, this paper proposes four clusters by grouping the city’s districts based on predominant land use (built-up, green urban areas) and tree canopy cover. This classification enabled the identification of intervention priority areas and suggestions of relevant nature-based solutions (NBS) to be implemented. The proposed method can serve other urban areas to perform a rapid assessment of their current needs and challenges in terms of ES provision.
Transitioning towards Organic Farming: Perspectives for the Future of the Italian Organic Wine Sector
Authors: Varia Francesca , Macaluso Dario , Agosta Ida , Spatafora Francesco , Dara Guccione Giovanni
Published: March 2021

In recent years, after the publication of Regulation (EU) 2018/848 on organic production and the labelling of organic products, all stakeholders have been considering threats and opportunities in the development of the organic food and beverage sector. The aim of the study outlined in this paper was to analyse the development prospects of the Italian organic wine sector in light of the Common Agricultural Policy (CAP) environmental and climate objectives. Specifically, the study focussed on applying a System Dynamics Approach (SDA) and a Network Analysis in order to explain how the most relevant social–economic determinants of the national organic wine sector are in all likelihood influencing the hoped-for shift from conventional to organic production. Such conversion appeared to be worth exploring because, despite the increasing global demand for organic wine, the economic effects on the entire system are still somewhat unclear from a dynamic perspective. The results of the study clearly demonstrated that public policies and regulatory actions at the national and European level will continue to be very influential for the future of the national organic wine system. Different development pathways, such as groups of operators and the adoption of the new national certification system for the sustainability of the entire wine supply chain, should be undertaken by Italian “small wine operators” in order to gain international markets.
Using an Artificial Neural Networks Experiment to Assess the Links among Financial Development and Growth in Agriculture
Authors: Magazzino Cosimo , Mele Marco , Santeramo Fabio Gaetano
Published: March 2021

Financial development, productivity, and growth are interconnected, but the direction of causality remains unclear. The relevance of these linkages is likely different for developing and developed economies, yet comparative cross-country studies are scant. The paper analyses the relationship among credit access, output and productivity in the agricultural sector for a large set of countries, over the period 2000–2012, using an Artificial Neural Networks approach. Empirical findings show that these three variables influence each other reciprocally, although marked differences exist among groups of countries. The role of credit access is more prominent for the OECD countries and less important for countries with a lower level of economic de-elopement. Our analysis allows us to highlight the specific effects of credit in stimulating the development of the agricultural sector: in developing countries, credit access significantly affects production, whereas in developed countries, it also has an impact on productivity.
What Are the Reasons Behind the Economic Performance of the Hungarian Beer Industry? The Case of the Hungarian Microbreweries
Authors: Jantyik Lili , Balogh Jeremiás Máté , Török Áron
Published: March 2021

In terms of absolute alcohol consumption and total quantity consumed, beer is the most consumed alcoholic beverage in Hungary. The Hungarian beer industry is highly concentrated, the three largest, foreign-owned companies ruled the market for almost 90% of total turnover in 2009–2017. The study investigates the factors influencing the Hungarian beer industry’s economic performance, special attention given to the microbreweries. The analysis applied panel-data linear models for the period of 2009–2017. The financial performance of breweries is represented by companies’ turnover, Earnings Before Interest and Taxes (EBIT) and profit along with explanatory variables of the age of brewery, Social Media activity, geographical location, direct sales, and impact of tax reduction. Breweries with direct sales channels reached significantly higher sales, EBIT and profit. Breweries situated in or close to the capital are the most profitable due to the higher demand for high-quality beer, in contrast, the distance from the capital had a negative impact on the firms’ performance. The Social Media activity–often used as the only promotion channel for the microbrewery–positively impacts the brewery’s profitability. Finally, tax reduction for small breweries introduced in 2012 had the most significant positive influence on the industry.
Emission Mechanisms of Fast Radio Bursts
Authors: Lyubarsky Yuri
Published: March 2021

Fast radio bursts (FRBs) are recently discovered mysterious single pulses of radio emission, mostly coming from cosmological distances (∼1 Gpc). Their short duration, ∼1 ms, and large luminosity demonstrate coherent emission. I review the basic physics of coherent emission mechanisms proposed for FRBs. In particular, I discuss the curvature emission of bunches, the synchrotron maser, and the emission of radio waves by variable currents during magnetic reconnection. Special attention is paid to magnetar flares as the most promising sources of FRBs. Non-linear effects are outlined that could place bounds on the power of the outgoing radiation.

Double charge exchange (DCE) reactions could provide experimentally driven information about nuclear matrix elements of interest in the context of neutrinoless double-β decay. To achieve this goal, a detailed description of the reaction mechanism is mandatory. This requires the full characterization of the initial and final-state interactions, which are poorly known for many of the projectile-target systems involved in future DCE studies. Among these, we intend to study the 20Ne + 130Te and 18O + 116Sn systems at 15.3 AMeV, which are particularly relevant due to their connection with the 130Te→130Xe and 116Cd→116Sn double-β decays. We measure the elastic and inelastic scattering cross-section angular distributions and compare them with theoretical calculations performed in the optical model, one-step distorted wave Born approximation, and coupled-channel approaches using the São Paulo double-folding optical potential. A good description of the experimental data in the whole explored range of transferred momenta is obtained provided that couplings with the 21+ states of the projectile and target are explicitly included within the coupled-channel approach. These results are relevant also in the analysis of other quasi-elastic reaction channels in these systems, in which the same couplings should be included.
Cities Exacerbate Climate Warming
Authors: Bounoua Lahouari , Thome Kurtis , Nigro Joseph
Published: March 2021

Urbanization is a complex land transformation not explicitly resolved within large-scale climate models. Long-term timeseries of high-resolution satellite data are essential to characterize urbanization within land surface models and to assess its contribution to surface temperature changes. The potential for additional surface warming from urbanization-induced land use change is investigated and decoupled from that due to change in climate over the continental US using a decadal timescale. We show that, aggregated over the US, the summer mean urban-induced surface temperature increased by 0.15 °C, with a warming of 0.24 °C in cities built in vegetated areas and a cooling of 0.25 °C in cities built in non-vegetated arid areas. This temperature change is comparable in magnitude to the 0.13 °C/decade global warming trend observed over the last 50 years caused by increased CO2. We also show that the effect of urban-induced change on surface temperature is felt above and beyond that of the CO2 effect. Our results suggest that climate mitigation policies must consider urbanization feedback to put a limit on the worldwide mean temperature increase.
Israeli Rousettus aegyptiacus Pox Virus (IsrRAPXV) Infection in Juvenile Egyptian Fruit Bat (Rousettus aegyptiacus): Clinical Findings and Molecular Detection

Published: March 2021

During 2019, five carcasses of juvenile Egyptian fruit bats (Rousettus aegyptiacus) were submitted to the Kimron Veterinary Institute. These bats exhibited typical poxvirus like lesion plaques of different sizes on the skin, abdomen and the ventral side of the wings. Clinical and histopathological findings suggested a poxvirus infection. Infectious virus was isolated from skin swabs, skin tissue and tongue of the dead bats and was further confirmed to be a Poxvirus by molecular diagnosis using PCR with pan-chordopoxviruses primers. All the dead bats were found positive for two Poxvirus genes encoding a metalloproteinase and DNA dependent DNA polymerase. In this study, a novel real time quantitative PCR (qPCR) assay was established to further confirmed the presence of specific poxvirus viral DNA in all pathologically tested tissues. Moreover, according to sequence analysis, the virus was found to be highly similar to the recently discovered Israeli Rousettus aegyptiacus Pox Virus (IsrRAPXV).
SARS-CoV-2 Neutralizing Antibodies: A Network Meta-Analysis across Vaccines
Authors: Rogliani Paola , Chetta Alfredo , Cazzola Mario , Calzetta Luigino
Published: March 2021

Background: There are no studies providing head-to-head comparison across SARS-CoV-2 vaccines. Therefore, we compared the efficacy of candidate vaccines in inducing neutralizing antibodies against SARS-CoV-2. Methods: A network meta-analysis was performed to compare the peak levels of SARS-CoV-2 neutralizing antibodies across candidate vaccines. Data were reported as standardized mean difference (SMD) since the outcome was assessed via different metrics and methods across the studies. Results: Data obtained from 836 healthy adult vaccine recipients were extracted from 11 studies. BBIBP-CorV, AZD1222, BNT162b2, New Crown COVID-19, and Sputnik V induced a very large effect on the level of neutralizing antibodies (SMD > 1.3); CoVLP, CoronaVac, NVX-CoV2373, and Ad5-nCoV induced a large effect (SMD > 0.8 to ≤1.3); and Ad26.COV2.S induced a medium effect (SMD > 0.5 to ≤0.8). BBIBP-CorV and AZD122 were more effective (p < 0.05) than Ad26.COV2.S, Ad5–nCoV, mRNA-1237, CoronaVac, NVX–CoV2373, CoVLP, and New Crown COVID-19; New Crown COVID-19 was more effective (p < 0.05) than Ad26.COV2.S, Ad5–nCoV, and mRNA-1237; CoronaVac was more effective (p < 0.05) than Ad26.COV2.S and Ad5–nCoV; and Sputnik V and BNT162b2 were more effective (p < 0.05) than Ad26.COV2.S. In recipients aged ≤60 years, AZD1222, BBIBP-CorV, and mRNA-1237 were the most effective candidate vaccines. Conclusion: All the candidate vaccines induced significant levels of SARS-CoV-2 neutralizing antibodies, but only AZD1222 and mRNA-1237 were certainly tested in patients aged ≥70 years. Compared with AZD1222, BNT162b and mRNA-1237 have the advantage that they can be quickly re-engineered to mimic new mutations of SARS-CoV-2.
Evaluation and Scenario Prediction of the Water-Energy-Food System Security in the Yangtze River Economic Belt Based on the RF-Haken Model
Authors: Chen Yan , Xu Lifan
Published: March 2021

As an important agricultural production area in China, the Yangtze River Economic Belt has a large amount of water resources and rich types of energy. Water and energy resources are the supporting basis of food production, and the production and use of energy also need to consume a large amount of water resources. The three affect each other and are interdependent. Paying attention to the synergistic security of water-energy-food system in the Yangtze River Economic Belt is important for regional economic development. This paper uses the pressure-state-response (PSR) model and selects 27 indicators to build an evaluation index system of the regional water-energy-food system. We use the random forest model to evaluate the security level of the Yangtze River Economic Belt from 2008 to 2017, and the Haken model is employed to identify the driving factors that dominate the synergistic evolution of the system. Then we take the identified factors as the key control variables under each scenario and launch a scenario simulation of some provinces in the Yangtze River Economic Belt in 2025. The results show that due to the improvement of water and energy utilization efficiency and the advancement of agricultural production technology, the level of water-energy-food security in the Yangtze River Economic Belt improved significantly from 2008 to 2017. Each province performs differently in different subsystems, with water resources security being better in the upper reaches and Zhejiang and Shanghai in the lower reaches, and food security being better in the middle and lower reaches. The level of energy security is high in Sichuan, Yunnan, and Guizhou in the upper reaches and Shanghai and Anhui in the lower reaches. According to the results of scenario prediction for Jiangsu Province and Hubei Province in 2025, implementing moderate management in accordance with current management objectives can increase the overall security of the system to level 4. The two provinces should focus on controlling water resources and energy consumption and improving the utilization efficiency of water and energy in agricultural production.
Cognitive Systematic Desensitization
Authors: Badri Malik B.
Published: March 2021

This paper discusses my innovative alterations and my Islamization of Wolpe’s systematic desensitization therapy applied during 1965 to treat a Moroccan patient. I have used this technique for the last fifty years; however, this is the first time I have described it in full detail. My main modifications were to (1) ask the patient to speak out loudly when detailing what she was imagining in order to enhance her involvement and her ability to imagine vividly; (2) encourage her to “horizontally” imagine and speak about other scenes of comparable anxiety-provoking instances to facilitate the transfer from clinic to real life. In fact, this turned out to be one of the earliest attempts to transform classical behavior therapy to cognitive therapy. Whenever she reported a great deal of anxiety, I discussed it with her and helped her discover her unconstructive thinking and Islamically change its negative irrationality. In doing so I combined desensitization with behavior rehearsal and spiritual Islamic therapy; (3) ask her to stop talking, instead of raising a finger, whenever she experienced a great deal of anxiety. My combination of the gradual approach of desensitization with cognitive therapy, behavior rehearsal, and spiritual therapy has shown how this combination can be of special relevance when treating Muslim patients.
Latina Muslim Producers of Online and Literary Countermedia
Authors: Avivi Yamil
Published: March 2021

Since 9/11, US English and Spanish language media have reported on the rise in Latino/a conversion to Islam. Western(ized) media images I examined for this essay about Latinas converting to Islam raise suspicions overpossible forced conversions, brainwashing, or abuse. What is evident and salient in these media portrayals, whether deliberately or unintentionally created, are the binaries (Western vs. non-Western, Christian vs. Muslim, and Arab vs. Latino) that limit understandings of how these women are self-empowered and make choices for themselves in their everyday lives as Latina Muslim converts. In effect, Western imperial ideologies and discourses in these media portrayals reinforce and normalize rigid state identitarian notions of Christian/Catholic Latinas living in Union City, New Jersey, a traditionally Catholic/Christian-majority and urban  Cuban-majority/Latino immigrant enclave since the 1940s-1950s. Now more alarming is this post-9/11 moment when “the Latino American Dawah Organization (LADO) estimated that Latina women outnumbered their male counterparts and reached 60 per cent,” as part of a changing religious and ethnic demographic that includes Muslim Arab and South Asian populations amidst Latino/a populations. In my research, it soon became evident that a variety of media sources perceived Union City as a prime site of Latino/a Muslim conversion post-9/11. This essay offers a specific look at the way newsmedia has portrayed Latina Muslims in Union City and how the cultural productions of these women challenge simplistic and Islamophobic views of Latinas who have converted to Islam post-9/11.

The Unavoidable Palm Oil Can Be Sustainable
Authors: YUE GH , Ye Baoqing , A Suwanto Antonius
Published: March 2021

The oil palm is the most productive oil-producing crop. To yield the same volume of oil that is from one hectare of palm, eight hectares of soybean are needed. Palm oil is used an ingredient in over 50% of packaged supermarket products and also as biofuels. The palm oil sector provides over 4.5 million jobs for on-farm laborers in developing countries. However, palm oil is often blamed for deforestation and loss of biodiversity. We argue that palm oil sustainability is not only about the environment and biodiversity but also about people and their prosperity. Palm oil sustainability can be achieved with joint efforts from palm oil players including the smallholders, plantation companies, governments, certification agencies, consumers and researchers.

This paper presents a novel configuration scheme for UPQC using ten switch topology. Generally, two six-switch inverters connected back to back will form the basic power structure of three wire three phase UPQC. But there are some switches which are less utilized all the time. In order to improve the efficiency of the system, or to improve the effective utilization of the IGBTs there is a need to reduce the switch count in the system. The proposed topology uses only ten switches and gives all the results pertaining to twelve switch toplogy. The Simulation results of proposed UPQC Topology are validated through MATLAB/Simulink environment.

COLLABORATIVE NEGOTIATION STRATEGY: A PANACEA FOR SUSTAINABLE INDUSTRIAL PEACE IN THE EDUCATIONAL SECTOR OF NIGERIA
Authors: BANKOLE Akanji Rafiu , ODERINDE Michael Adekunle
Published: March 2021

The persistent occurrence of industrial conflict in Nigeria educational sector particularly at tertiary level has apparently impacted negatively on the standard of education in the country. Past studies had traced the frequency of industrial actions in tertiary institutions to the type of negotiation strategy often employed by both labour leaders and management representatives. This study therefore examined the available negotiation strategies with a view to identifying the appropriate one and subsequently suggests what could be done for the two parties to voluntarily embrace the negotiation strategy considered appropriate and effective to achieve sustainable industrial peace. Using the archival method, the study observed that competing negotiation strategy was predominantly used in the tertiary institutions in Nigeria. And due to the confrontational and judgemental nature of the strategy, it could not stem the tide of incessant incidences of industrial action. Also, the study observed that the choice of competing negotiation strategy by both parties was probably due to their negative perception about each other and their behavioural orientation that is grossly defective. Based on the observation and the theoretical framework, it was suggested that training programme on some identified Behaviour Modification Skills (BMS) be organized for both parties. It is anticipated that by acquiring the skills, both parties would consciously change their negative perception to positive and their behavioural orientation would equally be enhanced. Thus, both parties would be willing to apply voluntarily the collaborative negotiation strategy considered appropriate and effective to attain sustainable industrial peace in our tertiary institutions.

Berdasarkan hasil penelitian dapat disimpulkan bahwa ada pengaruh breastfeeding dengan involusi uteri. Diharapkan ibu post partum selalu menjaga kesehatan dengan melakukan kontrol ulang pada petugas kesehatan, dan lebih aktif dalam mencari informasi kesehatan terutama mengenai pentingnya menyusui.
DAMPAK LATIHAN INTENSITAS BERAT PADA FUNGSI IMUN TUBUH
Authors: Hayati Hayati
Published: March 2021

Pemberian rangsang fisik berulang pada tubuh dapat menyebabkan proses adaptasi yang mencerminkan peningkatan kemampuan fungsional tetapi jika besarnya rangsangan tidak cukup untuk proses pembebanan, maka tubuh tidak akan mengalami proses adaptasi.Sebaliknya jika rangsang terlalu besar yang tidak dapat ditoleransi oleh tubuh akan menyebabkan jejas dan mengganggu keadaan homeostasis pada sistem tubuh. Latihan intensitas tinggi dapat meningkatkan hormone epinephrine dan cortisol di plasma yang dikenal sebagai efek immunomodulator Dampak negatif dari latihan akan muncul khususnya pada latihan intensitas berat, seperti penurunan sistem imun sehingga seorang atlet akan lebih gampang mengalami infeksi. Kejadian infeksi pada para atlet yang sedang dalam pemusatan latihan sudah banyak dilaporkan berdasarkan penelitian yang sudah dilakukan sebelumnya, tetapi masih belum jelas aspek-aspek ilmiah manakah yang paling merusak sistem imun dan lebih rentan terhadap infeksi. Jadi respon imun pada tubuh sebagai akibat dari latihan belum diketahui dengan jelas. Beberapa hasil penelitian belum ada kesepakatan mengenai beban dan bentuk latihan fisik yang meningkatkan atau menurunkan ketahanan tubuh. Secara umum penelitian menunjukkan bahwa latihan fisik intensitas tinggi menimbulkan kerusakan respon ketahanan tubuh, sedangkan pada laihan intensitas sedang belum ada kesepakatan dalam kesamaan hasil terhadap respon imun.

Kehamilan merupakan proses yang alamiah, kehamilan didefinisikan sebagai fertilisasi atau penyatuan dari spermatozoa dan ovum dan dilanjutkan dengan nidasi atau implantasi. Kehamilan resiko tinggi merupakan suatu kehamilan dimana jiwa dan kesehatan ibu dan atau bayi dapat terancam. Antenatal Care (ANC) adalah pengawasan sebelum persalinan terutama ditujukan pada pertumbuhan dan perkembangan janin dalam rahim dan ibunya. Tujuan umum dari penelitian ini adalah untuk mengetahui hubungan pengetahuan ibu hamil tentang resiko tinggi kehamilan dengan keteraturan Antenatal Care (ANC). Desain penelitian bersifat analitik dengan pendekatan cross sectional dan dihitung menggunakan metode Chi Square. Sampel penelitian merupakan 30 ibu hamil trimester III yang melakukan Antenatal Care trimester III di RB Soegiarti Surabaya pada bulan Juni 2014. Setelah dilakukan uji analisa data dengan menggunakan metode Chi Square test, dengan berdasarkan xÃ‚Â² tabel : 3,841 dan besaran xÃ‚Â² hitung : 2,16; diperoleh hasil xÃ‚Â² hitung < xÃ‚Â² tabel. Berdasarkan penelitian ini jumlah responden yang teratur melakukan Antenatal Care (ANC) yakni 14 responden (46.67%) dengan tingkat pengetahuan baik, 1 responden (3.33%) dengan tingkat pengetahuan kurang. Sedangkan resonden yang tidak teratur melakukan Antenatal Care (ANC) sebanyak 11 responden (36.67%) dengan tingkat pengetahuan baik dan 4 responden (13.33%) dengan tingkat pengetahuan kurang. Maka dapat disimpulkan bahwa Ã‚â€œtidak ada hubungan antara tingkat pengetahuan ibu hamil resiko tinggi kehamilan dengan keteraturan Antenatal Care (ANC) di RB Soegiarti SurabayaÃ‚â€. Dari hasil penelitian ini diharapkan kepada petugas kesehatan agar terus berupaya melaksanakan penyuluhan tentang resiko tinggi kehamilan dan akibat ketidakteraturan pemeriksaan Antenatal Care (ANC) terutama pada ibu hamil yang beresiko tinggi dengan menggunakan media yang mudah dimengerti oleh ibu hamil. Sedangkan bagi ibu hamil dianjurkan untuk meningkatkan pengetahuan, memperluas informasi tentang kesehatan ibu hamil dan kebutuhan gizi ibu hamil. Tetap melakukan pemeriksaan kehamilan secara rutin meskipun dalam kondisi normal serta menyertakan suami atau keluarga ibu hamil dalam kegiatan penyuluhan, sehingga tujuan kesehatan dapat tercapai.
HUBUNGAN ANTARA USIA DAN PARITAS DENGAN LETAK SUNGSANG PADA IBU BERSALIN
Authors: Sumiati Sumiati
Published: March 2021

Letak sungsang adalah janin terletak memanjang dengan kepala di fundus uteri dan bokong di bagian bawah kavum uteri. Menurut Manuaba (2001), kejadian letak sungsang sekitar 3-4 %, tetapi mempunyai angka morbiditas dan mortalitas janin yang tinggi. Di RSUD dr. M. Soewandhie Surabaya kejadian persalinan letak sungsang sebanyak 5 %. Banyak faktor yang menyebabkan meningkatnya persalinan dengan letak sungsang diantaranya oleh faktor usia ibu yang < 20 tahun atau > 35 tahun, dan kehamilan multiparitas pada ibu hamil dengan paritas 4 atau lebih terjadi insiden hampir sepuluh kali lipat dibanding ibu hamil nullipara, prematuritas, kelainan pada ibu atau janinnya. Penelitian ini bertujuan untuk mengetahui hubungan antara usia dan paritas dengan letak sungsang pada ibu bersalin di RSUD dr. M. Soewandhie Surabaya. Penelitian ini menggunakan metode analitik dengan teknik Simple Random Sampling, mengambil 255 sampel dari populasi sebanyak 1400 ibu bersalin di RSUD dr. M. Soewandhie Surabaya. Analisis data menggunakan tabulasi silang dengan uji chi-square. Berdasarkan hasil penelitian yang telah dilakukan diperoleh hasil bahwa dari 255 ibu bersalin di RSUD dr. M. Soewandhie Surabaya, adalah sebanyak 63 orang (24,70 %) mengalami letak sungsang, ibu bersalin mayoritas usia tidak beresiko (20-35 tahun), dan ibu bersalin mayoritas nonprimi (multipara atau grandemultipara). Setelah dilakukan uji chi-square dengan Î± = 0,05 didapatkan Ho ditolak. Jadi dapat disimpulkan bahwa ada hubungan antara usia dan paritas dengan letak sungsang pada ibu bersalin di RSUD dr. M. Soewandhie Surabaya. Oleh karena itu, sebaiknya untuk ibu bersalin melahirkan antara usia 20-35 tahun dan paritas tidak lebih dari tiga.

Sarcomas are a heterogeneous group of malignant mesenchymal neoplasms. This study aimed to investigate the immune-related prognostic gene signatures in the tumor microenvironment of sarcoma. The RNA-sequencing data and clinical phenotype data of 260 sarcoma samples and two normal samples were downloaded from The Cancer Genome Atla (TCGA) database. Tumor purity and immune cells infiltration were evaluated by Estimation of Stromal and Immune cells in Malignant Tumors using Expression data (ESTIMATE) deconvolution algorithm. Differentially expressed genes (DEGs) were screened in high vs. low immune score groups. Survival analysis was performed using Kaplan-Meier curve with log-rank test. Tumor infiltrating of immune cells was analyzed by Tumor Immune Estimation Resource (TIMER). High immune score and ESTIMATE score were associated with favorable prognosis. A total of 623 immune DEGs were screened. The majority of these genes (532 genes accounting for 85% of the DEGs) were up-regulated, and these genes were significantly enriched in various immune related biological processed and pathways, such as neutrophil activation, T cell activation, antigen processing and presentation. A total of 146 prognosis-related immune DEGs, and seven hub genes were identified, including B2M, HLA-DRB1, HLA-DRA, HLA-E, LCK, HLA-DPA1, and VAV1. Survival analysis showed that high expression of these genes was associated with a favorable prognosis. There were negative correlations between the expression of these hub genes and tumor purity, while positive correlations between expression of these hub genes and f infiltration levels of B cells, CD4+ T cells, CD8+ T cells, neutrophils, macrophages and dendritic cells. These results help to stratify patients with different immune subtypes and help to design immunotherapy strategies for these patients in sarcoma.
Lo statuto giuridico delle tombe nel mondo greco in Attica e al di fuori dell’Attica: un’analisi comparativa
Authors: Faraguna Michele
Published: March 2021

Il contributo si propone di indagare le questioni attinenti alla proprietà e ai meccanismi amministrativi e giuridici che regolavano l’organizzazione delle aree sepolcrali nonché lo statuto e le modalità di acquisizione, uso e trasmissione delle tombe nel mondo greco. A tal fine il quadro, relativamente più ampio, che emerge dall’analisi della documentazione dell’Atene classica (e in minor grado da Gortina e Anfipoli) viene messo a confronto con quello offerto dall’epigrafia di Rodi, Kos e altre città dell’Asia Minore in età ellenistica e romana. Nel caso di Atene, meglio nota è la situazione concernente i recinti funerari familiari che, dovunque fossero posti, erano certamente di proprietà privata e come tali, nonostante il loro ruolo «identitario» nella vita sociale e religiosa, potevano essere oggetto di compravendita. Si deve in ogni caso presupporre che l’organizzazione delle aree sepolcrali avvenisse innanzitutto in virtù del coinvolgimento della polis e dei suoi magistrati. Meno chiaro è lo statuto giuridico delle necropoli in cui venivano allestiti i lotti per la sepoltura dei cittadini di minore livello economico, dei meteci e degli schiavi che dovevano, secondo i casi, essere gestiti dalla città o, localmente, dai demi. Mentre la documentazione ateniese offre informazioni soprattutto sulle tombe individuali o familiari, le testimonianze epigrafiche provenienti da Kos e Rodi aprono uno spiraglio sul ruolo sempre più importante svolto dai koina (in particolare eranoi e thiasoi) a partire dal IV-III sec. a.C. nell’assicurare spazi comuni e riti funebri appropriati alle variegate componenti della popolazione escluse dalla cittadinanza. Essi diventavano in tal modo uno degli strumenti mediante i quali gli stranieri, interagendo al loro interno con i cittadini, aggiravano le limitazioni connesse al loro status e si assicuravano un luogo per la sepoltura e per essere ricordati anche dopo la morte.
