Wissenschaftsbasierte Politikberatung in der Corona-Krise: Die Ressortforschung des Robert-Koch-Instituts zwischen wissenschaftlichem Standard und politischem Handlungsdruck
Authors: Böcher Michael , Krott Max , Zeigermann Ulrike
Published: November 2021

Wissenschaftliche Politikberatung genoss während der ersten Welle der Corona-Pandemie so große Aufmerksamkeit, dass von manchen gar eine „Technokratisierung“ der Politik in Deutschland beklagt wurde. Der Artikel analysiert die Frage, ob die wissenschaftliche Politikberatung des Robert-Koch-Instituts (RKI) tatsächlich so viel Gewicht erlangte. Anhand einer Dokumentenanalyse zu fünf ausgewählten Fällen – der Vorlaufforschung des RKI sowie den Entscheidungen zum ersten Lockdown, zur Grenzschließung, Maskenpflicht und zu Schulschließungen – werden auf der Basis des RIU-Modells des wissenschaftlichen Wissenstransfers Integrationsprozesse zwischen Wissenschaft und Politik hinsichtlich der Rolle des RKI untersucht. Deutlich wird, dass das RKI als zuständige Ressortforschungseinrichtung für eine Politik im Krisenmodus unterschiedliche Integrationsleistungen erbrachte. Trotzdem war die Politik der dominante Akteur. Aufgezeigt wird, dass vorhandene unabhängige wissenschaftliche Expertise, die Vernetzung wissenschaftlicher Institutionen, enger Informationsaustausch mit politischen Akteuren und Medien die Chance erhöhen, dass wissenschaftliche Informationen von der Politik in Handlungsgrundlagen aufgenommen werden.
Die Corona-Pandemie als Wendepunkt in der deutschen Präventionspolitik?
Authors: Ewert Benjamin , Loer Kathrin
Published: November 2021

Der Beitrag widmet sich der Frage, inwieweit die Corona-Pandemie als „eruptives Ereignis“ einen paradigmatischen Wandel (Hall, 1993) in der deutschen Präventionspolitik herbeiführt. Erst recht vor dem Hintergrund der kollektiven Pandemieerfahrung müsste ein umfassender Gesundheitsschutz der Bevölkerung, so die leitende Annahme, durch eine konsistente präventionspolitische Programmatik und holistische Konzepte angestrebt werden. Der Beitrag diskutiert zunächst die Ursachen dafür, dass Präventionspolitik in Deutschland bislang so zaghaft vorging und vergleichsweise wenig Beachtung erhielt. Anhand von politikwissenschaftlichen Ansätzen zur Konzeptionalisierung von Policywandel werden drei Hypothesen zur Präventionspolitik entlang des Spektrums von übertragbaren und nicht-übertragbaren Krankheiten entwickelt, die auf Basis der empirischen Entwicklungen (März – Dezember 2020) getestet werden. Das Resultat der anschließenden Analyse fällt eindeutig aus: Wenngleich die Pandemie kurzfristig zu neuen Bearbeitungsmustern führte, sowohl was die angewandten präventionspolitischen Instrumente als auch die handelnden Akteurskonstellationen betrifft, gibt es keine Anzeichen für einen paradigmatischen Wandel. Die deutsche Präventionspolitik bleibt bis auf weiteres bruchstückhaft und inkonsistent.

Authors: Kumar Krishan , Renu
Published: November 2021

Multithreading is ability of a central processing unit (CPU) or a single core within a multi-core processor to execute multiple processes or threads concurrently, appropriately supported by operating system. This approach differs from multiprocessing, as with multithreading processes & threads have to share resources of a single or multiple cores: computing units, CPU caches, & translation lookaside buffer (TLB). Multiprocessing systems include multiple complete processing units, multithreading aims to increase utilization of a single core by using thread-level as well as instruction-level parallelism. Objective of research is increase efficiency of scheduling dependent task using enhanced multithreading. gang scheduling of parallel implicit-deadline periodic task systems upon identical multiprocessor platforms is considered. In this scheduling problem, parallel tasks use several processors simultaneously. first algorithm is based on linear programming & is first one to be proved optimal for considered gang scheduling problem. Furthermore, it runs in polynomial time for a fixed number m of processors & an efficient implementation is fully detailed. Second algorithm is an approximation algorithm based on a fixed-priority rule that is competitive under resource augmentation analysis in order to compute an optimal schedule pattern. Precisely, its speedup factor is bounded by (2?1/m). Both algorithms are also evaluated through intensive numerical experiments. In our research we have enhanced capability of Gang Scheduling by integration of multi core processor & Cache & make simulation of performance in MATLAB.

Published: November 2021

Background and Aim: Toxoplasma gondii infection arises in transplant recipient groups, but at varying frequencies. Reactivation of latent T. gondii infection in transplant patients is uncommon, but does occur. The incidence of reactivation is greater in patient groups receiving more aggressive immunosuppressive therapy. Early diagnosis and treatment should be considered in T. gondii-antibody-positive patients subjected to solid organ transplantation. The aim of this study was to estimate the seroprevalence of Toxoplasma gondii infection in renal transplant recipients in Khartoum, Sudan, using serological and molecular methods. Methods: This was a descriptive cross sectional, hospital based study, blood sample were collected from 108 participants; out of them 58 renal transplant recipient individuals and 50 healthy Blood donor attending Sudanese Kidney Association Hospital and Sudan Heart Center Blood Bank. Demographic data were collected by structured questionnaire. All samples were tested for anti-Toxoplasma IgG and IgM antibodies using ELISA, and PCR for detection of Toxoplasma DNA was performed. Results: The seropositivity of IgG anti-T. gondii antibodies was higher in renal transplant recipients than in blood donors (36.2% vs 32.0%). Anti-toxoplasma IgM was positive in one renal transplant recipient individual (1.70%), and no samples exhibit reactive IgM antibody for blood donors. None of the samples exhibited positivity to T.gondii DNA. Conclusion: the study showed a relatively high seroprevalence of T.gondii antibodies in renal transplant recipients and blood donor volunteers, on the other hand, the prevalence was much higher in the study conducted in pregnant woman in Sudan. Our study highlighted that asymptomatic blood donors, may constitute a significant risk of transmitting toxoplasmosis to susceptible recipients.

Along with toxic dyes textile dye wastewater contains various xenobiotic compounds therefore their treatment is necessary before discharging into the environment. Bioremediation was considered as one of the eco-friendly and self-sustainable treatment systems and amongst them cyanobacteria was considered as one of the best resources for the bioremediation of organic pollutants. Thus, in this present study, Spirulina sp. was evaluated for the treatment of real textile dye wastewater (RTDW) along with the removal of metal ions and other organic pollutants. The metabolic activities to Spirulina sp. leads to complete more than 98% decolorization of Reactive Brown GR11, Reactive Magenta HBB 26, Reactive Red Bs11 and Reactive Yellow 160 dye. However, to enhance the treatment efficiency of Spirulina sp. carbon and nitrogen sources were optimized. In the presence of 1% glucose and yeast extract Spirulina sp. showed 86% American Dye Manufacturers’ Institute (ADMI) removal and 83 % chemical oxygen demand (COD) reduction from the undiluted non-sterilize RTDW. The maximum treatment efficiency of Spirulina sp. was observed at pH-7 and 30 °C under optimized co-substrates. Degradation of RTDW and representative four azo dyes were further confirmed by using ultraviolet–visible spectrophotometry (UV–vis), High Performance Liquid Chromatography (HPLC), and Fourier- transform infrared spectroscopy (FTIR) analysis. Additionally, toxicity analysis was considered as the best method to evaluate the efficiency of treatment process. Phytotoxicity and cytotoxicity assay clearly show that Spirulina sp. treatment significantly reduces the toxic characteristics of RTDW.

Published: November 2021

The key element of human rights and the road to equity and dignity of women and children is the quality of care received. The provision of maternal health care is based on quality during pregnancy, and distinctly forty-eight hours after delivery, is an important contribution to saving women’s lives and preventing disabilities (Quah, 2016). Thus, the understanding of women's experiences and expectations through the continuum of prenatal care, delivery care and postnatal care is important for assessing the quality of maternal health care and the determination of problem areas requiring improvement. Women's satisfaction reflects women's judgment of various aspects of maternal health care, including organizational and interpersonal aspects. Multiple linear regression was used (IBM SPSS v.25) to test the main hypotheses for the present study. The ordinal regression was used to predict the value of a result variable (dependent variable) based on the value of two or more prediction variables (independent variables). This study identifies the relationship between maternal health services (prenatal & diagnostic care, delivery care and postnatal care) and women's satisfaction with the moderating role of doctor's behavior. The study finally determined the positive impact of health care services on women's satisfaction. The results also show that the doctor's behavior in health care services affect women's satisfaction and so, the alternate hypotheses are accepted. In this study, physicians were encouraged to give pregnant women thorough inspection and examination, treat them with courtesy and respect. The study also showed that, the government should focus on hiring additional employees to overcome workload.

Published: November 2021

Mathematical modelling of customer satisfaction has attracted strong academic interest over the centuries. Traditional satisfaction models have aimed at empirical generalizations and hence describe the customers’ behaviour parsimoniously at the market level. More recently, agent-based modelling and simulation has increasingly been adopted since it operates on the individual level and, thus, can capture complex emergent phenomena highly relevant in satisfaction research. Agent-based methods have been applied in this context both as intuition aids that facilitate theory-building and as tools to analyse real-world scenarios, support management decisions and obtain policy recommendations. This review addresses both streams of research. The research critically examine the strengths and limitations of agent-based modelling in the context of customer satisfaction. The target audience of the paper includes both researchers in marketing interested in new findings from the agent-based modelling literature and researchers who intend to implement agent-based models for their own research endeavours. Accordingly, cover pivotal modelling aspects in depth (concerning, consumer behavior) and outline existing models in sufficient detail to provide a proper entry point for researchers new to the field.

Abnormal uterine bleeding(AUB) is one of the most common gynaecological problems encountered in clinical practice. The PALM-COEIN classification for causes of AUB was proposed by the International Federation of Gynaecology and Obstetrics (FIGO) in 2011, which has gradually been applied in Bangladesh for the diagnosis of AUB.

Objective: the objective of this study was to evaluate the prevalence of chronic AUB according to FIGO classification in reproductive age women , carry out histopathological study and analyze it,s clinicopathological pattern.

Material and methods: this descriptive cross sectional study was carried out among 100 women of reproductive age (20-49 years) who presented with abnormal uterine bleeding (AUB) in the department of obstetrics and gynaecology of Dhaka Medical College Hospital during the period of January 2012 to December 2012. Clinical diagnosis was made according to PALM-COEIN classification on the basis of history, examination and necessary investigations. Endometrial sample and hysterectomy specimen were assessed by histopathology.

Result: Thirty five (35%) percent patients were 41-45 years. Ninety two (92%) patients were married ,2(2%) were unmarried and 6(6%) were widow. Among married women 98% were fertile and 2% were subfertile. Most common presenting symptom was menorrhagia (48%), followed by metrorrhagia (25%) and polymenorrhoea was observed in 22% cases. Ovulatory dysfunction (AUB-O) was the most common cause of abnormal uterine bleeding among the non structural causes and it was 44% . AUB-L were the most common (30%) among the structural causes, followed by AUB-A(10%) and AUB-P(5%). Regarding histopathological findings most of the patients( 34%) revealed unremarkable histopathological findings. Other findings were leiomyoma 27(27%), adenomyosis 13(13%) and fibroid uterus with adenomyosis in 5(5%) cases.

Conclusion: AUB –O was the leading cause of abnormal uterine bleeding and histopathological evaluation correlated well with the clinical diagnosis.

Here we report the case report of a patient with five consecutive complete hydatidiform moles without any normal pregnancy. A 41-years old lady, was referred to Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh with H/O repeated molar pregnancies. Her first molar pregnancy was in 2005, second in 2006, third in 2007 & fourth in 2014. All the molar pregnancies were managed by suction evacuation at her base hospital. Following evacuation of 4th molar pregnancy at base hospital, she was referred to BSMMU for subsequent management. Regular follow-up was done using molar card. All the pregnancies were complete hydatidiform mole (CHM) and were confirmed clinically and sonographically. None of the molar pregnancies needed treatment with chemotherapy. During her fifth molar pregnancy she developed shortness of breath and palpitation. Diagnostic work up in our hospital confirmed complete molar pregnancy with thyrotoxicosis, for which she received b-blocker agent and after normalization of thyrotoxicosis, she underwent total abdominal hysterectomy on 11. 10. 18. Now she is on regular follow up by serum bhCG and has no complication.

Implementasi Capacitated Vehicle Routing Problem with Time Windows dengan Pendekatan Algoritma Sweep untuk Distribusi Pengangkutan Sampah
Authors: Taptajani Dedi Sa'dudin
Published: November 2021

Vehicle Routing Problem (VRP) merupakan suatu permasalahan yang berkaitan dengan bagaimana menentukan rute yang dianggap optimal dan melibatkan lebih dari satu alat angkut demi memperhatikan beberapa kendala dalam melayani sejumlah tempat layanan sesuai dengan permintaan. Salah satu varian dari VRP adalah capacitated vehicle routing problem with time window (CVRPTW) varian ini menambahkan kendala kapasitas alat angkut sebagai salah satu pertimbangan didalam mengangkut ke masing masing tujuan dan kemudian memberikan jendela waktu didalam proses pengangkutannya. Tujuan dari penulisan ini adalah menjelaskan pembentukan model dari CVRPTW untuk permasalahan rute pengangkutan sampah dari tiap rumah Sampai Ke Tempat Pembuangan Akhir, dengan pertimbangan waktu yang tersedia dan kapasitas angkut alat angkut yang tersedia, Sedangkan Penyelesaiannya yaitu dengan menggunakan pendekatan algoritma sweep. Algoritma Ini merupakan algoritma yang terdiri dari dua tahap, pada tahapan pertama yaitu clustering dari masing masing rumah dan tahap selanjurtnya yaitu membentuk rute pengiriman untuk masing-masing cluster dengan metode Nearest Neighbour, kemudian dilanjutkan dengan menentukan kapasitas alat angkut terhadap waktu yang diperlukan untuk menentukan kapan sampah ini akan di angkut ke tempat pembuangan akhir. Studi ini sangat penting dilakukan dalam rangka menerapkan dasar untuk memahami kemungkinan meningkatkan tingkat layanan pada proses pengangkutan sampah di tingkat desa.
A Nexus among Reliability Improvement of Distribution System with Optimal Placement and Capacity of Wind-Based Distributed Generation Management
Authors: Shaddiq Syahrial
Published: November 2021

Along with the world population growth, the need for a source of electrical energy is higher, so a reliable system with higher capacities is expected. Renewable energy becomes an alternative that supports the goal of reducing the risk of disruption, thus increasing the distribution system’s reliability. A lot of industries and public settlement uses renewable sources of energy as an alternative power supply to comply their energy needs. This research uses wind turbine as a source of renewable energy in the distributed generation (DG). However, the required investment in wind-based DG is commonly considered too costly to deploy and require a proper planning on its placement method. The flower pollination algorithm (FPA) method could be a solution to achieve optimal placement of wind-based DG, thus increase the distribution system’s reliability, which is indicated by minimum energy not supplied (ENS) index.

Published: November 2021

Background and Objectives One of the most common complaint of tinnitus patients has been sleep disorder. The aim of this study was to evaluate the relationship between sleep disorder and tinnitus.Subjects and Method Patients with tinnitus from July 2018 till August 2019 were enrolled. Subjects who had any acute/chronic disease in the inner and middle ear or external auditory canal, sleep apnea and had more than 3 caffeinated beverages a day was excluded. Study participants completed Beck Depression Inventory (BDI), the tinnitus symptom questionnaire, tinnitus handicap inventory (THI), Pittsburg Sleep Quality Inventory (PSQI), pure tone audiometry, a full otologic examination and an interview on past medical history.Results THI was correlated with PSQI global score and BDI. The PSQI subscale most relevant to THI was PSQI 1 (subjective sleep quality). Hearing impairment was correlated with the THI functional subscale. BDI was individually related to PSQI.Conclusion Tinnitus is found to be highly related to sleep disorder, suggesting a common pathway of aggravation and treatment target. Tinnitus is also more affected by sleep disorder than by depression. A further examination and treatment of comorbid sleep disorder in tinnitus patients is recommended.
Copper barriers can cause behavioral artifacts in experiments with marine snails
Authors: Barnes AJ , Hill JM
Published: November 2021

Many gastropod species will not cross copper barriers; thus, copper has been used to manipulate their movements and minimize caging artifacts. However, as the reason for copper barrier avoidance is unknown, it is difficult to predict experimental artifacts that might result from its use. Copper can be toxic to gastropods, resulting in behavioral alterations or death, but there is little evidence copper barriers can cause these effects. In this study, we assessed whether copper mobilizes from copper barriers in water and alters gastropod behavior, using periwinkle snails Littoraria irrorata. Snails were placed in containers with and without copper tape and in copper solutions (0, 0.1, 0.2, 1.0, and 2.0 ppm) created by soaking copper tape in seawater. We measured the number of snails that climbed out of the water and the ability of snails to emerge and right themselves. Snails in 1.0, 2.0 ppm, and copper tape treatments were immobilized and did not climb out of the water or emerge from their shells. Snails in lower concentrations were more likely to climb out of the water. Low copper concentrations also reduced the number of snails emerging and righting, but those that did emerge did so in less time. When exposed snails were moved to clean water, snails previously immobilized by copper were quicker to crawl out of the water. Our results demonstrate that copper can mobilize from copper barriers resulting in alterations to snail behavior. To avoid experimental artifacts, we suggest the use of copper barriers be avoided in future experiments.
The Two cines con niño

Published: November 2021

The Two cines con niño  is the first genre study of Spanish-language child-starred cinemas. It illuminates continuities in the political use of the child protagonist in over fifty years of cinema from Spain and how the child-starred genres use the concept of childhood to define the nation’s past, present, and future. From Francoist popular to oppositional auteur films, and including Latin American cinema, this monograph examines dialogism in aesthetics, narratives, and genre functions. It demonstrates the impact of these narratives within Spanish film history and Francoist biopolitics, as well as providing a broader transatlantic perspective on the genre in select productions from Chile and Argentina. In-depth inquiry within its pages examines films by Pedro Almodóvar, Antonio del Amo, Montxo Armendáriz, Benjamín Ávila, Juan Antonio Bayona, José Luis Cuerda, Guillermo del Toro, Víctor Erice, Manuel Gutiérrez Aragón, Arantxa Lazkano, Luis Lucía, Paula Markovtich, Javier Ruiz Caldera, Carlos Saura, Imanol Uribe, Ladislao Vajda, Agustí Villaronga, and Andrés Wood.
