Authors: GANİYUSUFOĞLU Eda , KILINÇ Metin , RESİM Sefa , ŞEN Buket , SAĞER Hatice
Published: March 2023

Amaç: İnsanlarda metabolik ürünlerin üriner sistemin değişik bölümlerinde muhtemelen genetik ve/veya beslenme nedeniyle birikmesi ile taş oluştuğu
bilinmektedir. Yörelerdeki içme suları içeriğindeki element miktarlarının katkısının olduğu da düşünülmektedir. Bu çalışmada üriner sistem taşlarının kimyasal
bileşiminin yaş ve cinsiyete göre incelenmesi amaçlandı.
Gereç ve Yöntemler: Çalışmada, Ocak 2017 ile Şubat 2022 tarihleri arasında üroloji polikliniğine taşa bağlı klinik belirtilerle başvuran ve böbrek taşı saptanan
300 hastanın taş örnekleri (erkek n=207, kadın n=93) incelendi. Taşların analizi FT-IR Spektrofotometre cihazında ölçüm yapılarak değerlendirildi.
Yaş ve cinsiyet bilgileri arşiv taraması yoluyla elde edildi.
Bulgular: Hastaların yaş aralığı 1 ile 83 arasında değişmekteydi. Sonuçlar incelendiğinde taşlar görülme sıklığına göre kalsiyum okzalat monohidrat+kalsiyum
okzalat dihidrat (n=131, %43.66), kalsiyum okzalat monohidrat (n=43, %14.33), kalsiyum okzalat monohidrat+kalsiyum okzalat dihidrat+karbonat
apatit (n=28, %9.33), kalsiyum okzalat monohidrat+ürik asit (n=17, %5.66), ürik asit (n=12, %4), kalsiyum okzalat monohidrat+karbonat apatit (n=10,
%3.33) ve daha az olarak karışım halinde bulunan taşlar belirlendi. Taş oluşumunu cinsiyete göre incelediğimizde erkeklerde kadınlardan daha sık görüldüğü
tespit edilmiştir. Taşların kimyasal bileşimini yaşa göre incelediğimizde taş oluşumunun en sık 19-40 yaş, en az 12 -18 yaş arasında görüldüğü belirlenmiştir.
Sonuç: Kalsiyum elementinin baz alındığı taşların sık olarak görüldüğü, erkeklerde taş oluşumunun daha fazla olduğu ve yaş olarak 19-40 yaş aralığında taş
oluşumunun fazla görüldüğü söylenebilir. Aralıklı olarak üriner sistem taşı oluşumuna maruz kalan kişilerin taşlarının kimyasal bileşim yönünden değerlendirilmesi
ile hastalığın tedavisinin planlanması ve hastalığın tekrar etmesinin önlenmesine yardımcı olabileceği düşünülmektedir.

Authors: AKBULUT Ömer
Published: March 2023

Klinik öncesi araştırmalarda hayvan deneyleri sıklıkla kullanılmaktadır. Hayvan deneylerinin projelendirilmesinde örneklem büyüklüğünün belirlenmesi
için kullanılan güncel yöntemlerden biri “kaynak eşitlik yöntemi”dir. Bu çalışmada farklı araştırma tasarımları için alan yazındaki kaynak eşitlik yöntemi
eşitlikleri derlendi. Ayrıca eşitlikler bu çalışmada tek grup tasarımları ve faktöriyel tasarımlar için genişletildi. Kaynak eşitlik yöntemine göre örneklem büyüklükleri
ve bu örneklemlerin istatistiksel gücü belirlendi. Güç analizlerinin hesaplanmasında G*Power 3.1 yazılımı kullanıldı. Örneklem büyüklükleri tek
grup tasarımda 11 ile 21 arasında, ikiden fazla bağımsız grupta ise 15 ile 25 arasında bulundu. Tekrarlı ölçümlerde örneklem büyüklükleri bağımsız gruplara
göre daha küçük olup, faktöriyel tasarımlarda her bir alt grupta iki veya üç denek yeterli olduğu tespit edildi. Yöntem sürekli değişkenler için kullanılabilir.
Bu yöntem ile belirlenen örneklem büyüklükleri tüm tasarımlarda, hayvan deneyleri için uygun büyüklüktedir. Ancak istatistiksel güç değerleri %80 güç
düzeyine göre genellikle düşüktür.

Published: March 2023

Amaç: Günümüzün önemli bir sağlık sorunu olan çocukluk çağı obezitesiyle mücadalede etkin rol oynayabilecek öğretmenlerin obezite önyargı durumlarının
ortaya konulması önemlidir. Bu çalışmada Kırşehir il merkezindeki ilkokul öğretmenlerinin obezite önyargı durumları ve obez öğrencilere karşı
yaklaşımlarının belirlenmesi amaçlandı.
Gereç ve Yöntemler: Tanımlayıcı kesitsel tipteki bu çalışmaya 200 ilkokul öğretmeni dahil edildi. Veriler anket formu aracılığıyla yüz yüze toplandı. Öğretmenlerin
obezite önyargı durumları “GAMS-27 Obezite Önyargı Ölçeği” (OÖÖ) kullanılarak değerlendirildi. OÖÖ ölçeğinden alınan puanın artması
obezlere karşı önyargının artması anlamına gelmektedir. Tanımlayıcı bulgular sayı ve yüzdelerle ifade edildi. Karşılaştırmalı analizlerde Pearson ki-kare, t
testi ve tek yönlü ANOVA testi, post hoc analizlerde Duncan testi kullanıldı. p<0.05 değerleri anlamlı kabul edildi.
Bulgular: Öğretmenlerin yaş ortalaması 45.11±7.75 olup, %52.0’si kadın, %93.5’i evliydi. Öğretmenlerin obezite önyargı ölçeğinden aldıkları puan ortalaması
80.23±11.37’dir. Öğretmenlerin %2’si kendi ifadelerine göre kendilerini obezlere karşı önyargılı olarak tanımlamaktaydı, OÖÖ’ye göre ise öğretmenlerin
%35.5’i obezlere karşı öyargılı, %49.0’ı ise önyargıya eğimlimliydi. Obez öğrencilerin ders durumu daha kötü olduğunu, arkadaşlık ilişkilerinde diğer
öğrencilere göre daha kötü olduğunu beyan eden öğretmenlerin OÖÖ puanı daha düşükken, obez öğrencilerin kilolarından memnun olduğunu iddia eden
öğretmenlerin OÖÖ puanı daha yüksekti. Öğrenciler sağlıksız bir yiyecek tükettiklerinde karışmayacağını beyan eden öğretmenlerin OÖÖ puan ortalamaları
daha yüksekti. Öğretmenlerin hemen hemen tamamı öğrencilerin yeterli ve dengeli beslenmelerinin sağlanması için sağlık profesyonelleriyle işbirliğine
olumlu bakmaktaydı.
Sonuç: Öğretmenlerin çok azı kendilerinin obezlere karşı önyargılı olduğunu ifade etmekle birlikte, büyük bir kısmı obezlere karşı önyargılı veya önyargıya
eğilimli olarak tespit edilmiştir.

International Investment Law in the Shadow of Populism: Between Redomestication and Liberalism Re‐Embedded
Authors: Santos Álvaro
Published: March 2023

The international investment regime is in crisis, nowhere more so than in regard to the investor–state dispute settlement system. While several developing countries have been critical of the system for some time, rich countries like the US and EU states—once the principal promoters of this regime—are now acknowledging problems and advancing reforms. This change of position has been fueled by the mobilization of civil society and the emergence of domestic populist movements on both the right and the left, reflecting widespread discontent with the past three decades of neoliberal globalization and its effects on job losses, lower wages, and increasing inequality. This article argues that this shift has opened up a unique opportunity for developing countries that want reform, as there is less pressure (real or imagined) from rich countries to continue with an old model that no longer serves. Two paths present a possible way forward: (a) Participating countries can disengage from investor–state dispute settlement and opt for the redomestication of international investment law, rekindling the Calvo doctrine, or (b) they can follow John G. Ruggie’s “embedded liberalism” to re-embed the international investment regime with values and social objectives that are now deemed politically indispensable. This article explores each of these paths, with a particular focus on Latin America. It argues that although populism creates pressures to change or abandon the regime, in developing countries it also generates constraints that may prolong the status quo.

Purpose of the study. Evaluation of the diagnostic characteristics of the CA‑62 marker for epithelial carcinomas for detecting early‑stage prostate cancer in a double‑blind clinical study. This study is also focused on the possibility of using the CA‑62 antigen as an auxiliary tool for decision‑making in prostate cancer diagnosis.

Patients and methods. A blinded clinical study was conducted on 325 clinically verified blood serum samples. This includes 144 prostate cancer samples, 79 generally healthy volunteers‑men and 102 samples from patients with benign prostatic hyperplasia (BPH). Quantitative determination of the total and free prostate specific antigen (PSA) levels, as well as the CA‑62 marker of serum samples was performed using the electrochemiluminescent immunoassay ECLIA Elecsys Total and Free PSA (COBAS, Roche Diagnostics GmbH, Germany, EU) and the chemiluminescent immunoassay CLIA‑CA‑62 (JVS Diagnostics LLC, Moscow, RF).

Results. A comparison of the CA‑62 level with the results for total and free PSA, as well as other diagnostic methods (PCA3, PHI) for the analysis of the BPH and prostate cancer groups was performed. The results show that the CA‑62 marker has the highest PPV (94.4 %) and NPV (93.1 %). This may increase the reliability of the decision related to the presence of PC and be used by doctors as an argument as an argument for a prostate biopsy referral. It has been demonstrated that using the novel cancer marker CA‑62 makes it possible to detect up to 90 % of the early‑stage prostate cancer with 97.2 % specificity (AUC = 0.969).

Conclusion. Using the CA‑62 marker as an auxiliary diagnostic method within the PSA “grey zone” (from 2.5 to 10 ng/ml) made it possible to significantly increase the accuracy of detecting the PC early stages at biopsy up to 93.1 %. It will help the doctors to effectively differentiate between prostate cancer and benign prostatic hyperplasia.

Purpose of the study. The purpose of the study was to evaluate the dynamics of parameters of malondialdehyde (MDA), reduced glutathione and antioxidant enzyme activity in patients with advanced cervical cancer (CC) receiving anticancer treatment with dendritic cell vaccine (DCV).

Patients and methods. Levels of malondialdehyde (MDA), reduced glutathione and antioxidant enzyme activity were studied in 27 patients aged 27–65 years with advanced primary and recurrent CC receiving chemotherapy (CT) with DCV or DCV as monotherapy at a dose of 10 million cells intradermally once a week. The same indices were studied in 20 healthy women from the comparison group.

Results. The majority of patients showed the initial increase of MDA: in blood plasma by an average of 66.7 %, in red blood cells – statistically insignificant. After CT, MDA levels were elevated respectively in primary and recurrent patients in erythrocytes by 85.6 % and 96.4 % compared to donors, and by 53.9 % and 33.7 % compared to the initial values; the levels in plasma were elevated by 79.8 % and 57.1 % compared to donors. After 5–7 DCVs in combination with CT, MDA levels in erythrocytes and in blood plasma were similar to the donor values. MDA in erythrocytes of patients receiving DCV without CT decreased by 36 % compared to initial values. Oxidase activity of ceruloplasmin, initially increased by 34.2–57.1 %, normalized after DCV. Superoxide dismutase activity decreased by 16.7–27.3 % after 4–6 DCVs and normalized after 7 DCVs. Catalase activity, initially reduced by more than 40 %, remained 20–38 % lower than the norm at all stages of DCV. In this setting, hydrogen peroxide was probably inactivated by glutathione peroxidase whose activity was increased at all stages of treatment and decreased only when MDA was normalized after 7 DCVs.

Conclusion. Administration of 5–7 DCVs in combination with CT or as monotherapy to patients with advanced CC normalizes parameters of free radical oxidation and antioxidant system of the blood.

Published: March 2023

La fiebre de origen desconocido (FOD) representa un desafío diagnóstico para lo médicos, ya que existen múltiples diagnósticos diferenciales entorno a ello y su enfoque se basa en las caracteristicas clínicas distintivas de cada patología. Estás pueden agruparse en enfermedades cuya etiología es de origen infeccioso, autoinflamatorias o autoinmunes, neoplasias malignas, e incluso en un gran porcentaje de los casos no se encuentra una causa aparente. Cada una de ellas está asociada con síntomas, signos clínicos y hallazgos de laboratorio característicos, que si bien no son específicos cuando se analiza de forma individual, pueden ser de utilidad para establecer un diagnóstico y así mismo elegir el tratamiento apropiado para el paciente. Las clasificaciones etiológicas siguen siendo las mismas desde 1991, sin embargo, la evaluación clínica inicial combinado con los avances tecnológicos actuales, han permitido tener un mejor rendimiento diagnóstico y un tratamiento oportuno. A continuación, revisaremos definiciones recientes, abordaje clínico guiado por fases, seguido de los nuevos avances en medicina nuclear y metagenómica, con sus respectivas ventajas y limitaciones.

Effect of varying percentages of Co3O4 Nanoparticles on the Behavior of (ORR/OER) Bifunctional Co3O4/α-MnO2 Electrocatalyst
Authors: Zahoor Awan
Published: March 2023

Among all type of batteries, Lithium Air Batteries (LAB) are considered to be the most effective due to their highest energy density of around 11900 Wh/kg but there are some major issues are being faced by LAB such as large overpotential, poor cycle life, low current density, and decreased energy efficiency. The solution to these issues is primarily dependent on the proper selection of an electrocatalyst. A new approach for using a bi-functional electrocatalyst produced excellent results. Here, Co3O4/α-MnO2 composite has been considered as a bifunctional catalyst because cobalt oxide performed well in the Oxygen Evolution Reaction (OER) process while manganese oxide performed well in the Oxygen Reduction Reaction (ORR) process. A simple two-step hydrothermal process is used in this work to synthesize Co3O4/α-MnO2. This work focuses on the behavior of the composite electrocatalyst when varying percentages of Cobalt oxide (5%, 10%, 15%, and 20%) are deposited on the alpha-Manganese Oxide nanorods. The primary characteristics of each sample with different percentages of Cobalt Oxide are examined, and the performance of each sample is compared to one another. Several testing techniques like Cyclic Voltammetry (CV), Linear Sweep Voltammetry (LSV), X-Ray Diffraction (XRD), and Scanning Electron Microscopy (SEM) are performed on the samples. The combination of cobalt oxide and manganese oxide showed a synergistic effect and work as a bifunctional electrocatalyst. As the percentage of Co3O4 deposited on the α-MnO2 nanorod increased, it behaves more like an OER electrocatalyst leading to a decrease in charging potential. This work will help in finding an optimum amount of Co3O4 that should be deposited on α-MnO2 nanorods to get an efficient (ORR/OER) bifunctional electrocatalyst.

Various financial products have emerged in the era of the digital economy, including cryptocurrencies. In Indonesia, the Commodity Futures Trading Regulatory Agency (CoFTRA) regulates the use of cryptocurrencies. Cryptocurrencies are designated as investment assets that can be included as commodities in trading on futures exchanges but are prohibited from being used as a means of payment. Crypto investors in Indonesia alone in 2021 have reached 6.5 million people with a transaction value of Rp 370 trillion as of May 2021. This number continues to increase from the previous year, making crypto investors bigger than stocks or mutual funds. This study then analyzes the factors influencing the Indonesian people's interest in investing in cryptocurrencies. Data collection techniques were collected through questionnaires distributed online to 97 respondents, while data processing used multiple regression analysis. The findings of this study indicate that yield and flexibility have a positive and significant effect on interest in investing in cryptocurrencies. Meanwhile, the prohibition of cryptocurrencies has a negative impact on interest in investing in cryptocurrencies.

The paper discusses how President Joko Widodo articulated Islamic identity in his Foreign Policy during his first period of Presidency, 2014-2019. Through Constructivism approach and the concept of identity operated eclectically, the study finds that the factor of Islamic identity, to some extent, has contributed to the formation and implementation of foreign policy during this period. The Islamic identity can be approved by analytical descriptive explanation as it considered as the common measurement in international relation discipline, which is the platform and foreign policy orientation of Jokowi, in addition to his consistent diplomacy for Muslim world like Saudi Arabia-Iran conflict, Rohingya crisis, Afghanistan, and the existing two President Special Envoys for Middle East and OIC and for Cultural Cooperation and Interfaith Dialogues. This study shows that Jokowi was anti-Islam as accused by many during this period. Theoretically, the constructivism approach offers a new perspective on understanding the relationship of Islam and state in contemporary Indonesia.

The jig production process at PT IMS focuses on strength, function and production speed. The known problem is the higher strength and cost of producing jigs because the production process is not much at the trial and error stageThis study analyzes the static strength of the jig side frame bogie of the Jabodebek LRT with the parameters of the safety factor and deformation values.Static loading simulation method testing process used is conducted by using Finite Element Method software. It is counted manually to one of conditions to obtain the voltage value compared to the simulation results. This analysis is in form of measured jig design with safety factor and deformation value. The redesigning aim is weight decreasing efficiency. The simulation obtained result in jig early design is the safety factor value 25 and deformation value 0,045 mm. After jig dimension decreasing has been conducted, the redesigning result for safety factor value is 32 and the maximum deformation is 0,114 mm. The results of both simulations are considered as safe because the safety factor values are more than 2 and the deformation value are less than 0,5 mm. Redesigning by decreasing dimension gives better safety factor yet the deformation value increases.

Determinan Akuntabilitas Laporan Keuangan Non Laba dengan Komitmen Organisasi Sebagai Pemoderasi Masjid Kota Yogyakarta
Authors: Yani Indah , Fathmaningrum Erni Suryandari
Published: March 2023

Latar Belakang: Pada Era Society 5.0 topik yang dibahas dan ditangani tidak hanya pada organisasi laba namun organisasi non laba (masjid) juga memiliki peran penting. Informasi yang disampaikan pada web SIMAS (Sistem Informasi Masjid) belum menampilkan informasi keuangan, sedangkan dari beberapa tanggapan masyarakat mengenai penyampaian laporan keuangan masjid masih sangat sederhana. Sehingga dimungkinkan ada faktor yang dapat mempengaruhi pengurus masjid dalam menyiapkan dan menyampaikan informasi keuangan.Tujuan: Penelitian ini memiliki tujuan untuk mengetahui pengaruh kompetensi sumber daya manusia (SDM), sistem pengendalian internal, pemanfaatan teknologi informasi, peran stakeholder, dan standar pengelolaan terhadap kualitas laporan keuangan dengan komitmen organisasi sebagai pemoderasi. Metode Penelitian: Metode penelitian yang digunakan dalam penelitian ini adalah metode kuantitatif dengan mengumpulkan kuesioner dari pengurus masjid. Selanjutnya dilakukan analisis data dengan menggunakan teknik Partial Least Square (PLS).Hasil Penelitian: Hasil penelitian ini menunjukkan bahwa pemanfaatan teknologi informasi dan kompetensi SDM tidak berpengaruh, sedangkan sistem pengendalian internal, peran stakeholder dan standar pengendalian berpengaruh. Keterbatasan Penelitian: Keterbatasan yang dijumpai dalam penelitian ini adalah penelitian mengenai organisasi nonlaba masjid masih jarang diteliti sehingga sulit mendapatkan referensi literatur, dan peneliti hanya berfokus pada masjid yang berada dilingkungan kota. Keaslian/Kebaruan Penelitian: Penelitian ini membuktikan bahwa peran stakeholder dan standar pengelolaan mampu meningkatkan akuntabilitas laporan keuangan masjid. Sehingga pengurus masjid perlu mendapatkan pelatihan-pelatihan mengenai pembuatan laporan keuangan yang sesuai standar dan mudah dipahami masyarakat.
