Energy has been an essential factor in determining the governments' policies. The countries had to produce their own energy to decrease dependency on external resources. That also provided to gain a great importance on investment on power plants. In this study, a multi-objective Mixed-Integer Linear Programming (MILP) model synchronously optimizing five targets determined as decreasing carbon dioxide (CO 2 ) emission, increasing power consumption, increasing power plants, increasing energy generation and installed capacity was used. In described model, it was solved by considering renewable power plants in Turkey and fossil fuel-based power plants having most share in Turkey. By trying to minimize deviation values of Turkey's 2023 targets, it aimed to determine which power plants need to be increased. To determine the priorities of these targets, Ranking Approach for fuzzy numbers by Liou and Wang (1992) was used. Besides, Fuzzy Analytic Hierarchy Process (AHP) was used to prioritize investment planning of renewable power plants in Turkey and five different kinds of power plants under the visual pollution criteria based on amount of CO 2 emission released, environmental damage, capital costs, space requirement and provided employment were evaluated.

Sarcoidosis is a multisystem granulomatous disease which is observed worldwide. Sarcoidosis is one of the common causes of ocular inflammation. The choroidal vascularity index, defined as the ratio of the luminal area to the total choroidal area, is used as one of the biomarkers for assessing the choroid vascular state. We aimed to compare choroidal vascularity index and thickness measurements between sarcoidosis patients and healthy controls.Thirty-one patients with sarcoidosis and 31 age-gender matched healthy participants were recruited in this cross-sectional and comparative study. Choroidal vascularity index was defined as the ratio of luminal area to total choroidal area after binarization on optical coherence tomography images. Anterior segment examinations included central corneal thickness, corneal volume, anterior chamber depth, anterior chamber volume, and iridocorneal angle. Spectral-domain optical coherence tomography was used to measure peripapillary retinal nerve fiber layer thickness, choroidal thickness, and retinal vessel caliber.The mean choroidal vascularity index value was 61.6% in sarcoidosis patients and 62.4% in healthy controls (P = .69). The choroidal vascularity index and thickness were significantly correlated in both sarcoidosis (r = 0.41, P = .026) and control groups (r = 0.51, P = .006). Both the sarcoidosis and control groups had similar measured values for central corneal thickness, corneal volume, anterior chamber depth, anterior chamber volume, and iridocorneal angle (P > .05). Mean retinal nerve fiber layer, retinal arteriole and venule caliber, and choroidal thickness measurements did not differ significantly between the groups (P > .05).Sarcoidosis patients in quiescent period have similar choroidal vascularity index and thickness with healthy controls.

Objective: Telemedicine has been defined as a valuable tool in delivering care for COVID-19 patients. However, clinicians and policymakers should be convinced that traditional and new technological methods of clinical management may be equally effective. The purpose of this study was to generate some initial recommendations based on the clinical utility of videoconference consultation in forward triage and follow-up for COVID-19 patients. Material and Methods: This retrospective cross-sectional study evaluated the medical records of 100 COVID-19 patients consulted using a videoconference program (Skype), from September 1, 2020, to February 3, 2021. The data were analyzed on demographic characteristics, disease history, the need for physical examination after videoconference consultation, pre-diagnostics and diagnostics, treatment decisions, number of videoconference consultation sessions in follow-up, duration of sessions, and final outcome. Results: The male COVID-19 patients constituted 54% of the total sample. The median age was 51 (42-61) years. The median duration of the initial videoconference consultation session was 16 (12-21) minutes. Following the initial videoconference consultation session, 14 patients required follow-up with all face-to-face visits; the remaining patients were primarily followed with videoconference consultation sessions. For 25 patients, it was sufficient to provide only videoconference consultation sessions; they were not required to be in the hospital for physical examination or any subsequent investigation at all. A total of 14 patients were hospitalized. There was no statistically significant difference between the high-risk group and the other patients according to the components of the disease management process via videoconference consultation. Conclusion: Videoconference consultation enables a holistic assessment regardless of the patient's characteristics and allows for more time to be spent on each patient, particularly during the pandemic period without risk of contagion. It can be used as a forward triage and follow-up tool to identify patients in need of emergency hospitalization and continuous health care.
