Cok Kriterli Karar Verme Ile Avrupa Birligi ve Aday Ulkelerin Yasam Kalitesinin Analizi
European Foundation that gives advices in order to help to provide the best living and working conditions for European Countries, applied European Quality of Life Survey (EQLS) for 31 countries, including Turkey, in 2003, 2005 and 2007 years. The European Quality of Life Survey (EQLS) takes some kind of basic indicators like health, employment, income deprivation, education, family, social participation, housing, environment, transportation, safety, leisure time and life satisfaction into consideration. Studies that are made by using the life quality indicators enable identifying the demographic, social and economical profiles of individuals, groups or societies, determining targets to improve the existing level of life quality and comparing the current positions of their life qualities with other national or international levels. In the studies conducted, it is seen that mostly statistical analysis were used and the life qualities of the countries were handled within the light of various indicators. In this study, multi-criteria decision making is used for evaluating the indicators with a holistic point of view, concurrently. The life quality of European Union Countries and European Union Candidate Countries is analysed with VIKOR, which is one of the multi criteria decision making methods. By three different analysis with VIKOR for the years 2003,2005 and 2007, European Union Countries, Norway and European Union Candidate Countries which are Crotia, Macedonia and Turkey are evaluated according to their life quality indicators. Benefitting from the study results, life qualities of the countries for the years 2003, 2005 and 2007 are evaluated.Multi-Criteria Decision Making, VIKOR Method, European Union, Quality of Life
SWARA/WASPAS methods for a marine current energy plant location selection problem
Increasing energy demand in the World has led countries to use renewable energy sources as a result of kinetic energy transformations of nature's building blocks such as wind, solar, hydrogen and water. This orientation has also increased technology, creativity, research and development and applicability. With the increasing renewable energy production researches, methods that minimize the harmful effects to the nature continue to be developed. This study is about a location selection problem for Turkish first marine current energy production plant that planned to be established. In order to solve the location problem a multi criteria decision model is proposed with 4 main criteria, 12 criteria and 3 alternatives. The criteria in proposed model are weighted with the SWARA method and the alternatives determined in the model according are ranked by WASPAS method. In Turkey, with made researches applicability of energy production from marine current has expressed many times, but an actual developments on the issue until today has not been made. Therefore, location selection problem for marine current energy plant is the first study to be introduced to the literature with its combined application method. (C) 2020 Elsevier Ltd.

SERS-active linear barcodes by microfluidic-assisted patterning
AbstractSimple, low-cost, robust, and scalable fabrication of microscopic linear barcodes with high levels of complexity and multiple authentication layers is critical for emerging applications in information security and anti-counterfeiting. This manuscript presents a novel approach for fabrication of microscopic linear barcodes that can be visualized under Raman microscopy. Microfluidic channels are used as molds to generate linear patterns of end-grafted polymers on a substrate. These patterns serve as templates for area-selective binding of colloidal gold nanoparticles resulting in plasmonic arrays. The deposition of multiple taggant molecules on the plasmonic arrays via a second microfluidic mold results in a linear barcode with unique Raman fingerprints that are enhanced by the underlying plasmonic nanoparticles. The width of the bars is as small as 10 μm, with a total barcode length on the order of 100 μm. The simultaneous use of geometric and chemical security layers provides a high level of complexity challenging the counterfeiting of the barcodes. The additive, scalable, and inexpensive nature of the presented approach can be easily adapted to different colloidal nanomaterials and applications.Abstract

An extremely rare case of testicular malign neoplasm; alveolar subtype of rhabdomyosarcoma with long term follow-up.
Testicular neoplasm usually occur in men aged between 15 and 35. These are solid organ tumours and also should be operated when there is a suspicious clinical findings. Testis tumours are levelled after histopathology evaluation. The medical, surgical and follow-up strategies of well know testis tumours, such as seminomas, non-seminom germ cell tumours, have been established. In case of testis tumours rare entities may occur as rhabdomyosarcoma.We here presented a rare case of alveolar subtype of rhabdomyosarcoma in testis with long term follow-up
Polarization and health-related behaviours and outcomes during the COVID-19 pandemic: a systematic review protocol.
INTRODUCTION
The COVID-19 pandemic affected people's health behaviours and health outcomes. Political or affective polarization could be associated with health behaviours such as mask-wearing or vaccine uptake and with health outcomes, e.g., infection or mortality rate. Political polarization relates to divergence or spread of ideological beliefs and affective polarization is about dislike between people of different political groups, such as ideologies or parties. The objectives of this study are to investigate and synthesize evidence about associations between both forms of polarization and COVID-19 health behaviours and outcomes.
METHODS
In this systematic review, we will include quantitative studies that assess the relationship between political or affective polarization and COVID-19-related behaviours and outcomes, including adherence to mask mandates, vaccine uptake, infection and mortality rate. We will use a predetermined strategy to search EMBASE, Medline (Ovid), Cochrane Library, Cochrane COVID-19 Study Register, Global Health (Ovid), PsycInfo (Ovid), Web of Science, CINAHL, EconLit (EBSCOhost), WHO COVID-19 Database, iSearch COVID-19 Portfolio (NIH) and Google Scholar from 2019 to September 8 2023. One reviewer will screen unique records according to eligibility criteria. A second reviewer will verify the selection. Data extraction, using pre-piloted electronic forms, will follow a similar process. The risk of bias of the included studies will be assessed using the JBI checklist for analytical cross sectional studies. We will summarise the included studies descriptively and examine the heterogeneity between studies. Quantitative data pooling might not be feasible due to variations in measurement methods used to evaluate exposure, affective and political polarization. If there are enough relevant studies for statistical data synthesis, we will conduct a meta-analysis.
DISCUSSION
This review will help to better understand the concept of polarization in the context of the COVID-19 pandemic and might inform decision making for future pandemics.

Arrays of Plasmonic Nanoparticles Assembled on Patterns of Polymer Brushes Fabricated by Soft Lithography
This work employed end-grafted poly ethylene glycol PEG and hydroxyl-terminated poly 2-vinylpyridine P2VP polymer chains for selective immobilization and patterning of plasmonic nanoparticles NPs . A soft lithographic method which called micromolding in capillaries MIMIC used in this study. The polymers are deposited the capillary flow by the channels which formed by an elastomeric mold and substrate. The localized coatings are referred as polymer brushes and show great promise in the assembly of NPs due to the tunable interaction between the polymer chains and particles. The results show that the width of patterns defined by the channels is smaller than 1.5 µm with a length of around 0.5 cm. Also, the heights of the patterns are ~3.5 nm for P2VP and ~10 nm for PEG. The fabricated structures exhibited high levels of plasmonic activity and surface enhanced Raman scattering due to the immobilized Au NPs. The patterning polymer brushes and plasmonic NPS over large areas by a low-cost process show great promise for a variety of applications that range from molecular sensors to biotechnolog
How to update a living systematic review and keep it alive during a pandemic: a practical guide.
BACKGROUND
The covid-19 pandemic has highlighted the role of living systematic reviews. The speed of evidence generated during the covid-19 pandemic accentuated the challenges of managing high volumes of research literature.
METHODS
In this article, we summarise the characteristics of ongoing living systematic reviews on covid-19, and we follow a life cycle approach to describe key steps in a living systematic review.
RESULTS
We identified 97 living systematic reviews on covid-19, published up to 7th November 2022, which focused mostly on the effects of pharmacological interventions (n = 46, 47%) or the prevalence of associated conditions or risk factors (n = 30, 31%). The scopes of several reviews overlapped considerably. Most living systematic reviews included both observational and randomised study designs (n = 45, 46%). Only one-third of the reviews has been updated at least once (n = 34, 35%). We address practical aspects of living systematic reviews including how to judge whether to start a living systematic review, methods for study identification and selection, data extraction and evaluation, and give recommendations at each step, drawing from our own experience. We also discuss when it is time to stop and how to publish updates.
CONCLUSIONS
Methods to improve the efficiency of searching, study selection, and data extraction using machine learning technologies are being developed, their performance and applicability, particularly for reviews based on observational study designs should improve, and ways of publishing living systematic reviews and their updates will continue to evolve. Finally, knowing when to end a living systematic review is as important as knowing when to start
