Authors: Kornyushin O. V. , Sakeian I. S. , Kravchuk E. N. , Vasilevsky D. I. , Danilov I. N. , Neimark A. E.
Published: February 2022

Type 2 diabetes prevalence is increasing dramatically worldwide. Conservative therapy doesn’t bring stable effect and is often insufficient, not to mention the lack of prospects to cure the disease. Fortunately, accumulating evidence points towards the notion that a complete remission of type 2 diabetes is feasible following a choice of surgical interventions. The efficacy of bariatric surgery in particular for achieving glycemic control has highlighted surgery as a candidate curative intervention for type 2 diabetes. When compared to intensive medical therapy and lifestyle intervention, metabolic surgery has shown superiority in achieving reducing number of medications and metabolic factors improvement, which translates in long-term benefits on diabetes progression and complications. Understanding factors that predict diabetes remission can help to select patients who will benefit most from bariatric surgery and to choose the most effective type of operation. This literature review analyzes studies of the most significant clinical and biochemical predictors of remission of type 2 diabetes mellitus after bariatric interventions, as well as highlights well-known mathematical prediction models.

Representación sacramental del sacerdote en la comprensión de Ratzinger y Greshake
Authors: Hernández Rodríguez Antonio Diego
Published: February 2022

Por la ordenación, el sacerdote representa sacramentalmente a Cristo. Por la misma ordenación, puede actuar en nombre de la Iglesia. Joseph Ratzinger y Gisbert Greshake han reflexionado sobre lo que comporta esta representación, su origen profundo y sus consecuencias concretas en la vida del ministro y en el conjunto de la Iglesia. Ambos lo hacen también con distintas posturas, pues mientras para Ratzinger la representación cristológica es la clave desde la que comprender posteriormente el ministerio eclesial, Greshake defiende que en el ministro se da una doble representación como núcleo teológico desde el que comprender e interpretar el sacerdocio. Este debate que se daba en el último cuarto del siglo pasado se presenta hoy desde la articulación de las dimensiones cristológica y pneumatológica del ministerio.
Diagnostic performance of the fully automated Roche Elecsys SARS-CoV-2 antigen electrochemiluminescence immunoassay: a pooled analysis
Authors: Lippi Giuseppe , Henry Brandon M. , Adeli Khosrow
Published: February 2022

Objectives

Among the diagnostic tests that have recently become commercially available for diagnosing coronavirus disease 2019 (COVID-19), the fully-automated Roche Elecsys severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antigen electrochemiluminescence immunoassay (ECLIA) is one of the most widespread for its adaptability within a system of laboratory automation, rapidity and high-throughput. This article is aimed to provide the results of the first pooled analysis of its accuracy for diagnosing SARS-CoV-2 infections.

Content

We carried out an electronic search in Scopus and Medline, without language or date restrictions (i.e., up to January 18, 2022), to identify articles where the diagnostic performance of Roche Elecsys SARS-CoV-2 antigen ECLIA was compared with that of reference molecular diagnostic techniques.

Overall, 11 studies were identified, 10 of which (n=6,095 swabs) provided necessary data for inclusion in a pooled analysis. The pooled diagnostic sensitivity, specificity and area under the curve (AUC) in nasopharyngeal samples were 0.68 (95%CI, 0.66–0.70), 0.99 (95%CI, 0.99–0.99) and 0.958 (95%CI, 0.936–0.980), respectively. The cumulative observed agreement with reference molecular assays was 89.5% and the kappa statistic was 0.735 (95%CI, 0.716–0.754). The pooled diagnostic sensitivity in samples with high viral load (i.e., cycle threshold values <28–30) was 0.95 (95%CI, 0.92–0.97).

Outlook

The results of this pooled analysis confirm that the fully-automated Roche Elecsys SARS-CoV-2 antigen ECLIA has high diagnostic specificity and optimal diagnostic sensitivity for identifying nasopharyngeal samples with higher viral load, thus making it a reliable technique for mass screening and for supporting strategies based on shorten isolation and/or quarantine.
Droplet epitaxy symmetric InAs/InP quantum dots for quantum emission in the third telecom window: morphology, optical and electronic properties
Authors: Holewa Paweł , Kadkhodazadeh Shima , Gawełczyk Michał , Baluta Paweł , Musiał Anna , Dubrovskii Vladimir G. , Syperek Marcin , Semenova Elizaveta
Published: February 2022

The rapidly developing quantum communication technology requires deterministic quantum emitters that can generate single photons and entangled photon pairs in the third telecom window, in order to be compatible with existing optical fiber networks and on-chip silicon photonic processors. InAs/InP quantum dots (QDs) are among the leading candidates for this purpose, due to their high emission efficiency in the required spectral range. However, fabricating versatile InAs/InP QD-based quantum emitters is challenging, especially as these QDs typically have asymmetric profiles in the growth plane, resulting in a substantial bright-exciton fine structure splitting (FSS). This hinders the generation of entangled photon pairs and thus, compromises the versatility of InAs/InP QDs. We overcome this by implementing droplet epitaxy (DE) synthesis of low surface density (2.8 × 108 cm−2) InAs
x
P1−x
QDs with x = (80 ± 15)% on an (001)-oriented InP substrate. The resulting QDs are located in etched pits, have concave bases, and most importantly, have symmetric in-plane profiles. We provide an analytical model to explain the kinetics of pit formation and QD base shape modification. Our theoretical calculations of electronic states reveal the properties of neutral and charged excitons and biexcitons confined in such QDs, which agree with the optical investigations of individual QDs. The optical response of QDs' ensemble suggests that FSS may indeed be negligible, as reflected in the vanishing degree of linear polarization. However, single QD spectrum gathered from an etched mesa shows moderate FSS of (50 ± 5) µeV that we link to destructive changes made in the QD environment during the post-growth processing. Finally, we show that the studied DE QDs provide a close-to-ideal single-photon emission purity of (92.5 ± 7.5)% in the third telecom window.
Efficient modal analysis of plasmonic nanoparticles: from retardation to nonclassical regimes
Authors: Yan Wei , Qiu Min
Published: February 2022

With recent developments in nanotechnologies, metal nanoparticles permeate a wide range of dimension scales, from light wavelength-scale domains down to a few nanometers approaching electronic scales. The electrodynamics at metal surfaces hosts a rich interplay between plasmon oscillations, retardation effects of light, and nonclassical (quantum) effects of electrons. Incorporating all these effects and modeling optical responses of nanoparticles generally rely on pure numerical methods, which are, however, disadvantageous in physical interpretations and computational speed. Herein, we establish a modal method that accurately predicts plasmon responses of metal nanoparticles, including both retardation and nonclassical corrections on an equal footing. The proposed method, based on electrostatic plasmon modes, is parameterized by a set of geometrically dependent factors, which, once computed, can be repeatedly used for same-shaped nanoparticles independent of size and material composition. The predictive accuracy of the method is examined for single nanoparticles, multi-scale plasmonic architectures—such as dimer structures with deep-nanometer gap—and geometrically deformed structures, with feature dimensions ranging from a few nanometers to hundreds of nanometers.

Published: February 2022

In this paper, we reviewed the recent advances in nanoscale modifications and evaluated their potential for dental implant applications. Surfaces at the nanoscale provide remarkable features that can be exploited to enhance biological activities. Herein, titanium and its alloys are considered as the main materials due to their background as Ti-based implants, which have been yielding satisfactory results over long-term periods. At first, we discussed the survivability and the general parameters that have high impacts on implant failure and the necessities of nanoscale modification. Afterward, fabrication techniques that can generate nanostructures on the endosseous implant body are categorized as mechanical, chemical, and physical methods. These techniques are followed by biomimetic nanotopographies (e.g., nanopillars, nanoblades,etc.) and their biological mechanisms. Alongside the nanopatterns, the applications of nanoparticles (NPs) including metals, ceramics, polymers,etc., as biofunctional coating or delivery systems are fully explained. Finally, the biophysiochemical impacts of these modifications are discussed as essential parameters for a dental implant to provide satisfactory information for future endeavors.
Neurobiological effects of urban built and natural environment on mental health: systematic review
Authors: Bolouki Ahmad
Published: February 2022

Although rapid global urbanization improves people in many ways, it also increases the prevalence of major mental disorders in urban communities. Exposure to natural surroundings, whether real or virtual, on the other hand, has been found to reduce arousal and stress. The purpose of this study is to provide an overview of the existing literature on how brain function changes when exposed to natural and urban settings. As a highly effective technique for determining human brain activity, this review considers literature using neuroimaging techniques, i.e., electroencephalography (EEG), functional magnetic resonance imaging (fMRI), and functional near-infrared spectroscopy (fNIRS). SCOPUS and PubMed were searched for peer-reviewed literature published prior to September 2021. Twenty-six sources were included, returning 263 papers; 18 empirical articles published from 1991 to 2021 were included in the final synthesis. EEG findings were generally consistent with those obtained from fMRI/NIRS data. Natural settings were linked to greater alpha EEG values and fewer demands on information processing and stronger functional connectivity in fMRI/NIRS studies, which indicate feelings of relaxation and restoration. These findings offer a better understanding of the functional activities during environmental exposures and also imply that nature exposure improves cognitive functions and mental health.

Media memiliki pengaruh penting dalam meningkatkan literasi masyarakat tentang kesadaran lingkungan. Namun, pemberitaan tentang lingkungan kurang mendapatkan prioritas dibanding berita politik dan ekonomi, dan bahkan isu lingkungan lebih banyak dibingkai sebagai komoditas politik daripada literasi lingkungan.Riset ini bertujuan untuk menjelaskan bagaimana isu reklamasi pantai utara Jakarta tampil dalam media daring Kompas.com berdasarkan kategorisasi yang dominan dan fungsi pemberitaan dalam perspektif jurnalisme lingkungan hidup. Untuk itu riset ini menggunakan perspektif teori jurnalisme lingkungan dan metode analisis isi kuantitatif .Hasi riset ini menunjukkan bahwa pemberitaan reklamasi pantai Jakarta selama tahun 2016 lebih banyak ditampilkan dalam kategorisasi isu hukum dan peraturan perundangan, dan lebih banyak menggunakan fungsi informasi sebagai fungsi pemberitaan dominan. Dengan demikian riset ini menunjukkan media lebih banyak menyajikan isu lingkungan dari perspektif hukum dalam konteks politik daripada literasi tentang persoalan lingkungan. Hal ini terjadi karena tahun 2016 merupakan tahun politik menjelang Pilkada DKI Jakarta di tahun 2017 sehingga isu lingkungan lebih ditampilkan sebagai komoditas politik, minim dalam penerapan prinsip jurnalisme lingkungan.

A Parent Survey Assessing Association of Exposure to Gun Violence, Beliefs, and Physician Counseling
Authors: Silver Alyssa H. , Curley Michael , Azzarone Gabriella , Dodson Nancy , O’Connor Katherine
Published: February 2022

OBJECTIVES

The study objectives are to assess associations between hospitalized children’s parental exposure to gun violence (GV) and parental beliefs about guns and gun safety; secondarily, the authors aim to describe parental views on the pediatrician’s role in firearm injury prevention (FIP) counseling.

METHODS

Parents residing with children <20 years old hospitalized at a quaternary care hospital in a large city were eligible. Researchers administered verbal surveys between March 2017 and July 2019. We analyzed data (Wilcoxon rank-sum, χ2, or Fisher’s exact tests, as appropriate) to compare the characteristics of those with exposure to GV and those without, and to assess associations of those with and without GV exposure with various beliefs.

RESULTS

Enrollment included 225 parents or guardians. Although 75.5% agreed pediatricians should talk to parents about safe gun storage, 8.9% reported FIP counseling by their child’s doctor. There were no substantial differences in characteristics between those with GV exposure versus those without. The study revealed that 60.0% of participants reported hearing gunshots, and 41.8% had a friend/relative who had been shot; only 29.8% reported neither. There were no differences between groups in gun-related beliefs regardless of exposure.

CONCLUSIONS

In this population, there was no association between exposure to GV and gun-related beliefs. Most parents are receptive to FIP counseling, yet few have discussed FIP with their pediatrician despite high exposure to GV in this community. Nearly all parents agreed with the use of gunlocks and stricter laws for background checks. Regardless of exposure to GV, parents agreed with safe gun storage and support strengthening gun safety laws.
On the Expediency and Possibilities of Approximating a Pure Delay Link
Authors: Zhmud Vadim , Dimitrov Lubomir , Sablina Galina , Roth Hubert , Nosek Jaroslav , Hardt Wolfram
Published: February 2022

When solving problems of controlling an object with delay, it is often necessary to approximate a pure delay link with a minimum phase link in order to ensure the possibility of using analytical methods for regulator design. There are many approximation methods based on the Taylor series expansion, as well as modified methods. The most famous one is the Padé approximation method. The known approximation methods have significant drawbacks, which this paper reveals. However, there are other methods of forming other types of filters that can serve as a better approximation in determining the delay relationship, although they are not used for these purposes. In particular, methods of forming the desired differential equation of a locked-loop system of a given order by the method of numerical optimization are known. In this case, the locked-loop system behaves like a filter of the corresponding order, the numerator of which is equal to one, and the specified polynomial is in the denominator. Modeling has shown that such a filter is an effective alternative approximation of the delay link and can be used for the same purposes for which it was supposed to use the Padé approximation. The polynomial coefficients in the literature were calculated only up to the 12th order. The higher the polynomial order is, the more accurate the approximation is.
Polynomial Approximations for Several Neural Network Activation Functions
Authors: Marshalko Grigory , Trufanova Julia
Published: February 2022

Active deployment of machine learning systems sets a task of their protection against different types of attacks that threaten confidentiality, integrity and accessibility of both processed data and trained models. One of the promising ways for such protection is the development of privacy-preserving machine learning systems, that use homomorphic encryption schemes to protect data and models. However, such schemes can only process polynomial functions, which means that we need to construct polynomial approximations for nonlinear functions used in neural models. The goal of this paper is the construction of precise approximations of several widely used neural network activation functions while limiting the degree of approximation polynomials as well as the evaluation of the impact of the approximation precision on the resulting value of the whole neural network. In contrast to the previous publications, in the current paper we study and compare different ways for polynomial approximation construction, introduce precision metrics, present exact formulas for approximation polynomials as well as exact values of corresponding precisions. We compare our results with the previously published ones. Finally, for a simple convolutional network we experimentally evaluate the impact of the approximation precision on the bias of the output neuron values of the network from the original ones. Our results show that the best approximation for ReLU could be obtained with the numeric method, and for the sigmoid and hyperbolic tangent – with Chebyshev polynomials. At the same time, the best approximation among the three functions could be obtained for ReLU. The results could be used for the construction of polynomial approximations of activation functions in privacy-preserving machine learning systems.
A SLAM system based on Hidden Markov Models
Authors: Fuentes Oscar , Savage Jesus , Contreras Luis
Published: February 2022

We present a graph SLAM system based on Hidden Markov Models (HMM) where the sensor readings are represented with different symbols using a number of clustering techniques; then, the symbols are fused as a single prediction, to improve the accuracy rate, using a Dual HMM. Our system’s versatility allows to work with different types of sensors or fusion of sensors, and to implement, either active or passive, graph SLAM. The Toyota HSR (Human Support Robot) robot was used to generate the data set in both real and simulated competition environments. We tested our system in the kidnapped robot problem by training a representation, improving it online, and, finally, solving the SLAM problem.

There has been an increasing requirement for more efficient and less iatrogenic therapies for drug delivery, encouraging researches to develop new vectors that ensure targeted delivery of drugs and other therapeutic agents in medicine. Traditional synthetic drug vectors which include polymer and lipid particles are not preferred for clinical applications due to their high cytotoxicity, greater immunogenicity and low cell membrane penetrability. On the other hand, natural particulates ranging from pathogens to mammalian cells are specially optimized forin vivofunctions and possess features desirable for drug delivery vectors. Biomimetics involves exploiting biological organisms, cells and molecules or deriving inspiration from them. The Biomimetic Nanoparticles have ushered a new generation of drug carriers, attracting researchers because of their excellent biocompatibility, biodistribution, low chances of recognition and removal by the immune system. Their ability to mimic the bio-structure and function of the biological system makes them reliable drug delivery vectors especially for disease targeting. The advanced biotechnology tools used for engineering synthetic and natural derived nano-systems along with better understanding of biological systems, have enabled researchers to apply these ideas to the delivery of drugs, small interfering RNA, proteins and other therapeutic agents. This review summarizes recent advances in biomimetic nanoparticles used for targeted drug delivery in medicine, obtained by processing synthetic materials using biomimetics. The challenges of biomimetic delivery systems and future directions are also discussed and proposed herein.

A series of organophosphorous compounds (3a - 3m) containning phosphonate functional group have been synthesized efficiently with high speed and good yield. All the compounds were correctly characterized using different spectroscopic techniques (IR, Mass, 1H,
13C and 31P-NMR). These compounds were screened for their antibacterial activity. All the synthesized derivatives showed good antibacterial activities. 3g compound showed the best activity against one Gram-positive (Staphylococas aureus) and two
Gramnegative (Escherichia coli and Klebsiella pneumoniae) species. In order to predict binding interaction between active site of bacterial enzyme and 3g, molecular docking was performed, into the crystal structures of DNA-gyrase cleavage complex of S. aureus (Gram+ve)
with PDB_ID:5CDQ and the cleavage complex of topoisomerase Top. IV of K. pneumoniae (Gram-ve) with PDB_ID:5EIX using autodock/vina, an open source software. The molecule showed strong interaction due to H bonding, pi- pi interaction and hydrophobic interaction with active site amino
acids. The synthesized compounds were also submitted to drug likeness model programs e.g molinspiration and osiris to predict bioavailability and toxicity profiles which are important for selection of the best drug candidate among all synthesized compounds. With these results we conclusively
demonstrated the selected structural analogues can act as potential antibacterial agents.

Bu araştırmada, poliamid 6 (PA 6) matris içerisine katı yağlayıcı olarak grafit (G) ve vaks (V) ilave edilerek elde edilen kompozitlerin kuru kayma şartları altındaki tribolojik özellikleri incelenmiştir. PA 6/grafit/vaks polimer karışımları ikiz vidalı ekstruderde hazırlanmıştır. Araştırmada kullanılan numuneler enjeksiyonda kalıplama yöntemi ile üretilmiştir. Aşınma deneyleri, ASTM G99’a uygun olarak disk üzerinde pim aşınma cihazında gerçekleştirilmiştir. Deneyler 50N ve 100N aşındırma yükü altında 0,4 m/s, 0,8 m/s ve 1,2 m/s kayma hızında ve 4000m kayma mesafesinde gerçekleştirilmiştir. PA 6 matris içerisine ilave edilen katı yağlayıcılar (grafit, vaks) sayesinde sürtünme katsayısı ve aşınma oranında azalma olduğu görülmüştür. Deney sırasında pim üzerinde yapılan kayma yolu sıcaklık ölçümlerinde PA 6/vaks kompozitinin daha az ısındığı gözlemlenmiştir. Ayrıca PA 6/grafit/vaks kompozitlerin aşınma yüzeylerinin mikro-yapıları SEM yardımı ile incelenmiştir.

Authors: TEPE Ahmet
Published: February 2022

Bu çalışmada, film soğutmada aralıklı ve üçgen iç-bükey (AÜİB) rampanın film soğutma etkinliğine ve akış karakteristiklerine etkisi sayısal olarak incelenmiştir. AÜİB rampa, jet akışı ana akışın etkisinden korumak için yüzey üzerinde film soğutma deliğinin yüzey ile birleştiği ve ana akışın geldiği baş tarafa yerleştirilmiştir. AÜİB rampanın en uygun tasarım parametrelerini belirlemek için 10˚, 25˚ ve 45˚ olmaz üzere üç farklı eğim açısı (αr), 0,15, 0,30 ve 0,50 olmak üzere üç farklı boyutsuz rampa yüksekliği (h/d) incelenmiştir. Bununla birlikte hesaplamalar 0,30, 0,60, 0,85 ve 1,25 üfleme oranında (M) gerçekleştirilmiştir. Gerçek çalışma şartlarına uygun olarak film soğutmanın fiziksel özelliklerini doğru tespit edebilmek için, hesaplamalarda ana akım için hava, yüzeye enjekte edilen akışkan için ise CO2 kullanılmıştır. Buna bağlı olarak jet akışı ile ana akış yoğunluk oranı (YO) 1,50’dir. CO2 yüzeye yüzeyle açısı αj=35˚ olan ve 4 mm çaplı dairesel kesitli jet deliğinden enjekte edilmiştir. Sayısal çalışmalar Hesaplamalı Akışkanlar Dinamiği’nde (HAD) kullanılan Ansys FLUENT 19.2 ile Transition k-kl-ω türbülans modeli kullanılarak gerçekleştirilmiştir. Sonuçlar rampanın olmadığı geleneksel düz yüzeyle karşılaştırılmıştır. Sayısal sonuçlara göre rampa yüksekliğinin artması ve rampa açısının azalması FSE’ni arttırmıştır. Alan-ortalamalı FSE’nde geleneksel film soğutmaya göre en yüksek artış h/d=0,50 ve αr=10˚ olan rampa tasarımında %305,44 olarak elde edilmiştir.

Günümüz rekabet ortamında işletmeler rekabet gücünü artırmak için müşterilerin çeşitli ve kişiye özel taleplerine hızlı ve yüksek verimlilik ile yanıt vermeleri gerekmektedir. Üretim sistemlerinde verimliliği ve esnekliği artırmak amacıyla Amerikan Ford şirketi tarafından ortaya çıkan seri üretim (montaj hattı), Japonya’daki Toyota firması tarafından geliştirilen Toyota Üretim Sistemi (TÜS) ve grup teknolojisine dayalı Hücresel Üretim Sistemi (HÜS) gibi farklı üretim sistemleri geliştirilmiştir. Ancak, dinamik talepler, ürünlerin kısa yaşam döngüsü ve yüksek çeşitlilik nedeniyle montaj hattı ve TÜS’de verimlilik düşmektedir. Sony ve Canon gibi Japon şirketleri, pazar taleplerini karşılamak için bir Japon hücresel üretim sistemi geliştirmişlerdir ve geleneksel HÜS'den ayırmak için bu üretim sistemine seru üretim sistemi adı vermişlerdir. Literatürde seru üretim sistemi ile ilgili az sayıda çalışma yapılmıştır. Özellikle Türkçe literatürde, seru üretim sistemlerini inceleyen sadece iki çalışmaya rastlanmıştır. Bu yönüyle çalışmanın literatürdeki bu boşluğu doldurması hedeflenmektedir. Bu çalışmada seru üretim sistemi ele alınarak bu konuda kapsamlı literatür taramasının yanı sıra montaj hattının seru üretim sistemine dönüştürme (hat-seru dönüşümü) ve siparişlerin toplam gecikmelerini minimize eden çizelgeleme problemleri aynı anda matematiksel bir model olarak önerilmiştir. Modelin çözümü için GAMS paket programı kullanılmıştır ve sonuçlar analiz edilmiştir.
Yeni bir matematiksel model ve hibrit meta sezgisel ile kaynak kısıtlı projelerin çizelgelenmesi: Bir vaka çalışması
Authors: BAŞAR Ayfer
Published: February 2022

Projeler, başlangıç ve bitiş tarihi belli olacak şekilde belirlenmiş bir zaman diliminde özgün çıktıların sunulmasının hedeflendiği çalışmalardır. Gerçek hayatta her projenin bütçe, zaman, kapsam ve kalite kısıtları vardır. Projelerin başarıyla sonuçlanabilmesi için bu kısıtlar dâhilinde tüm kaynakların etkin kullanımı, zaman ve bütçe kısıtlarına uyulması ve başta müşteri olmak üzere bütün paydaşların memnun edilmesi şarttır. Her alanda gittikçe zorlaşan rekabet koşulları nedeniyle projelerin başarılı bir şekilde tamamlanması her geçen gün zorlaşmaktadır. Özellikle proje çıktısı olan yeni ürün veya servisin pazara çıkış süresini hızlandırmak amacıyla zaman baskısı artık her işletmede rastlanan bir durumdur. Bunun için işletmeler, kaynak kısıtlı projelerin aktivite zamanını doğru planlamak için yeni yöntem arayışına girmek durumundadır. Bu çalışmada, kaynak kısıtlı projelerin aktivitelerinin zaman planına uygun olarak tamamlanabilmesi için aktiviteler arasındaki mantıksal ilişkileri dikkate alacak şekilde yeni bir matematiksel model önerilmiştir. İşletmelerdeki projelerin aktivite sayısının fazla olduğu durumlarda karmaşık yapıya sahip bu modelin en iyi çözümü bulunamamaktadır. Bu nedenle önerilen hibrit metasezgisel sayesinde kaynak kısıtlı projelerin aktivitelerinin zamanında tamamlanması probleminin çözülmesi hedeflenmiştir. Geliştirilen model ve metasezgisel yöntem, Türkiye’de hizmet vermekte olan bir bilgi teknolojileri şirketinin proje aktivite zaman planlaması için uygulanmıştır. Bu yaklaşım ile geciken proje ve aktivite sayısının çok az olduğu, yöntemlerin başarı yüzdesinin yüksek olduğu ve planların gerçekçi olduğu görülmüştür.

Listen and you will see the person through the dementia
Authors: Estrada Rita
Published: February 2022

Dementia is an ever-increasing health and social problem, with a growing number of people being affected worldwide. As dementia progresses, dependency on others increases, requiring the presence of caregivers. Caregivers tend to focus on the diagnosis itself – dementia – which makes it difficult to see the person in their uniqueness. The person is there, and can be seen by listening, which requires time and communication skills. The voices of older adults living with several types of dementia, collected while working as a psychologist in a nursing home, are presented in the first person to bring forward the person they are. These excerpts of interactions illustrate the basic psychological need of relatedness, which is built through interaction, stories, and touch, and the needs of competence and autonomy. The framework of this paper encompasses validation therapy, person-centered care, and self-determination theory. Two conclusions emerge: Seeing the person through the dementia enables an adequate psychological assessment and a helpful supportive psychotherapy, and it also makes us acknowledge and help satisfy the three basic psychological needs of relatedness, competence, and autonomy.
