Nuclear Security Risk Analysis: An Insider-Outsider Collusion Scenario

This study analyses the vulnerability of the physical protection system (PPS) deployed at a hypothetical facility. The PPS is designed to prevent and eliminate threats to nuclear materials and facilities. The analysis considers possible outsider and insider threats. A modified adversary sequence diagram (ASD) evaluates threat pathways to test an insider-outsider collusion case. The ASD also measures the probability of adversary interruption by demonstrating the methodology for a typical nuclear facility

DETERMINAN KEPATUHAN MEMBAYAR IURAN JAMINAN KESEHATAN NASIONAL PADA PESERTA MANDIRI DI KELURAHAN MALALAYANG SATU KOTA MANADO

Jaminan Kesehatan Nasional adalah program asuransi bersifat wajib yang dengan tujuan untuk menjamin masyarakat dalam memperoleh kebutuhan dasar kesehatan dan pelayanan kesehatan yang bersifat adil dan bermutu. Dalam pelaksanaan program JKN, semua peserta wajib membayar iuran JKN secara patuh selambat-lambatnya tanggal 10 setiap bulannya. Peserta mandiri ialah setiap orang yang bekerja atas risiko sendiri dan membayar iuran JKN secara mandiri. Kelurahan Malalayang Satu merupakan kelurahan dengan jumlah peserta JKN mandiri kedua terbanyak di Kota Manado dengan total tunggakan iuran mencapai Rp.1,6 miliar. Pengetahuan dan pendapatan adalah faktor predisposisi yang memengaruhi perilaku patuh peserta mandiri dalam membayar iuran. Penelitian ini bertujuan untuk melihat hubungan pengetahuan dan pendapatan peserta mandiri dengan kepatuhan membayar iuran JKN di Kelurahan Malalayang Satu, Kota Manado. Jenis penelitian yang digunakan adalah kuantitatif desain observasi analitik dengan pendekatan cross sectional study. Populasi pada penelitian ini adalah peserta JKN mandiri di Kelurahan Malalayang Satu berjumlah 1.018 jiwa, dengan jumlah sampel 100 orang responden yang menjadi sampel diambil dengan menggunakan teknik quota sampling. Hasil penelitian uji chi square memperlihatkan terdapat hubungan yang signifikan antara pengetahuan peserta mandiri dengan kepatuhan membayar iuran JKN (p=0,000) dan terdapat hubungan yang signifikan pula antara pendapatan peserta mandiri dengan kepatuhan membayar iuran JKN (p=0,000). Saran kepada BPJS Kesehatan dan pihak Kelurahan Malalayang Satu agar dapat memberikan sosialisasi terkait hak dan kewajiban peserta, aplikasi Mobile JKN, serta program REHAB, selain itu diharapkan juga untuk membentuk kader JKN yang dapat membantu dalam penagihan iuran JKN

Variation in postoperative outcomes of patients with intracranial tumors: insights from a prospective international cohort study during the COVID-19 pandemic

Background: This study assessed the international variation in surgical neuro-oncology practice and 30-day outcomes of patients who had surgery for an intracranial tumor during the COVID-19 pandemic. Methods: We prospectively included adults aged ≥18 years who underwent surgery for a malignant or benign intracranial tumor across 55 international hospitals from 26 countries. Each participating hospital recorded cases for 3 consecutive months from the start of the pandemic. We categorized patients’ location by World Bank income groups (high [HIC], upper-middle [UMIC], and low- and lower-middle [LLMIC]). Main outcomes were a change from routine management, SARS-CoV-2 infection, and 30-day mortality. We used a Bayesian multilevel logistic regression stratified by hospitals and adjusted for key confounders to estimate the association between income groups and mortality. Results: Among 1016 patients, the number of patients in each income group was 765 (75.3%) in HIC, 142 (14.0%) in UMIC, and 109 (10.7%) in LLMIC. The management of 200 (19.8%) patients changed from usual care, most commonly delayed surgery. Within 30 days after surgery, 14 (1.4%) patients had a COVID-19 diagnosis and 39 (3.8%) patients died. In the multivariable model, LLMIC was associated with increased mortality (odds ratio 2.83, 95% credible interval 1.37–5.74) compared to HIC. Conclusions: The first wave of the pandemic had a significant impact on surgical decision-making. While the incidence of SARS-CoV-2 infection within 30 days after surgery was low, there was a disparity in mortality between countries and this warrants further examination to identify any modifiable factors

New Luminescent 1D and 2D d10 Coinage Metal Organic Chalcogenolate Coordination Polymers

SSCI-VIDE+CDURABLE+SHA:ABH:ADMInternational audienceCoordination polymers (CPs) with chalcogenate ligands (-Ch-R = S-R, Se-R, Te-R) and d10 coinage metals (M(I) = Cu, Ag and Au ), are well-known for their photoluminescence properties and offer a sustainable opportunity to replace rare earth elements based materials that are considered as critical raw materials by the European union.[1,2] The photoemission of Metals Organic Chalcogenolates (MOCs) is mostly attributed to the presence of d10 coinage metals and their ability to display metallophilic interactions that result in the possibility to fine tune their photophysical properties to get a large palette of color emission with high quantum yields. [3,4]. Herein, we will show the effect of the synthesis protocol on the coordination polymer’s crystal structures and their physical properties. In fact, different exciting crystal structures features were identified from powder and single crystal X-ray diffraction data. Depending on the nature of the synthesis protocol and thiol linker, the structures of the copper MOCs could be centrosymmetric (P21/c) or non-centrosymmetric (Cc, Pca21). The rich variety of the crystal structures impacts directly the photophysical properties with a shift from red to green emission. Moreover, an interesting Second Harmonic Generation response for the non-centrosymmetric compounds was detected, opening a new field of optical applications. [1] H. Furukawa, K. E. Cordova, M.
