Authors: Dvořák Pavel , Vyskočil Vlastimil
Published: January 2023

A huge diversity of problems currently solved by modern analytical chemistry requires a great variety of approaches, methods, and materials used for finding optimal solutions. Although the advantages and possibilities of current spectrometric and separation methods are fascinating, it can certainly be declared that modern electrochemical and electroanalytical methods may represent a competitive alternative, especially if they use novel electrode materials and progressive approaches. In this review, our contribution in the field of non-traditional film electrodes based on mercury, bismuth, antimony, and carbon conductive layers applied in voltammetric and amperometric analysis of organic compounds is documented. The possibilities and limitations of these novel electrochemical sensors, their advantages and drawbacks, their practical applications, as well as their contribution in the field of modern analytical chemistry are presented.

Published: January 2023

The present work deals with the development of a prolonged release matrix tablet of the readily soluble drug pramipexole. The new excipient Kollidon SR (a mixture of 80% polyvinyl acetate and 20% polyvinylpyrrolidone) and hypromellose K15M were used as polymers to control drug release from selected prototypes. Various polymer concentrations were tested to achieve a stable and pH independent release of pramipexole of 0.26 mg over 24 hours; samples were prepared by wet granulation and compression of matrix tablets. Drug release was monitored in dissolution media with pH values from 1.2 to 6.8 and compared with a reference product based on a hydrophilic matrix with a combination of three different polymers. The required release profile of the low-dose drug formulation was achieved using 60.0% (w/w) of Kollidon SR in all dissolution media and the selected formulation F2 demonstrated a sufficient alcohol resistance up to the ethanol concentration of 40% (v/v).

Predložená práca sa zaoberá vývojom matricovej tablety s predĺženým uvoľňovaním ľahko rozpustného liečiva pramipexolu. Ako polymér riadiaci uvoľňovanie liečiva z vybraných prototypov bol použitý nový excipient Kollidon SR (zmes 80 % polyvinylacetátu a 20 % polyvinylpyrolidónu) a hypromelóza K15M. Testovali sa rôzne koncentrácie polymérov s cieľom dosiahnúť stabilné a pH nezávislé uvoľňovanie pramipexolu 0,26 mg po dobu 24 hodín, vzorky boli pripravené vlhkou granuláciou a lisovaním matricových tabliet. Uvoľňovanie liečiva bolo sledované v disolučných médiách s hodnotami pH od 1,2 až po 6,8 a porovnávané s referenčným prípravkom na báze hydrofilnej matrice s kombináciu troch rôznych polymérov. Požadovaný liberačný profil nízkodávkového liečiva bol dosiahnutý použitím 60,0 hm.% Kollidonu SR vo všetkých médiách a vybraná formulácia F2 vykazovala dostatočnú odolnosť aj voči pôsobeniu etanolu až do koncentrácie 40 obj.%.
Experiment for "Polarimetry" Teaching
Authors: Kalina Jiří , Lach Michal
Published: January 2023

Polarimetry enables one to quantitatively determine certain substance (optically active substances) in a solution on the basis of rotation of the plane of the polarized light of a single wavelength. The main goal of this work is to measure concentration of optically active substances using homemade device, so called "polarimeter". The device measures the degree of light attenuation instead of the polarization angle of the polarized light as in commercial instruments. The designed "polarimeter" allows one to determine the concentration of optically active substances. It is a home-made device using a smartphone with a selected software, which is many times cheaper than commercially available ones. The authors would like to see the device find use in polytechnic education of students.

Polarimetrie umožňuje kvantitativně stanovit určitou látku (opticky aktivní látky) v roztoku na základě měření úhlu stočení roviny polarizovaného světla jedné vlnové délky. Hlavním cílem této práce je měření koncentrace opticky aktivních látek pomocí podomácku vyrobeného přístroje, tzv. „polarimetru“. Zařízení měří míru zeslabení světla namísto úhlu stočení polarizovaného světla jako u komerčních přístrojů. Navržený „polarimetr“ umožňuje stanovit koncentraci opticky aktivních látek. Jde o podomácku vyrobené zařízení využívající chytrý telefon s vybraným softwarem, který je mnohonásobně levnější než komerčně dostupné. Autoři by rádi viděli využití zařízení v polytechnické výchově studentů.

Development of Local Politics through Permitting Local Political Parties
Authors:   Center for Civic Politics Research, Lee Jeong Jin
Published: January 2023

The current Political Party Act regulates the establishment of regional parties by limiting registration as a political party only when there is a central party in the capital city and five or more city/provincial parties nationwide. This is the reason why local politics cannot escape from the influence of central politics and local issues are not highlighted in local elections. Academia and civil society are demanding that the Political Party Act be amended to allow local parties, and related amendments have been proposed several times in the National Assembly.
Looking at overseas cases, regional parties are allowed in countries with developed party politics, such as the United States, the United Kingdom, Japan, and Germany, and the influence of regional parties in local elections is increasing.
Therefore, in terms of realizing grassroots democracy, it is necessary to allow participation of various political groups, including local parties, in local elections. In addition, in the long term, it is necessary to review the constitutional party-related provisions to expand the freedom of political party activities.

Published: January 2023

Küreselleşme ile uluslararası finansal akımların güçlenmesi ardından, bu sürecin çeşitli sektörler üzerindeki etkileri uzun zamandır tartışılmakta ve araştırılmaktadır. Bir ülkeye yönelik fon akımlarının o ülkedeki fiyatlar genel düzeyi üzerinde güçlü etkilerinin olması beklenir. Hatta bu olası etkileri kontrol etmek için zaman zaman ekonomi politikalarına başvurulduğu izlenmektedir. Kısa vadeli fon akımlarının, öncelikli olarak finansal kesimi etkilemesi beklenir. Fakat bunun yanında pek çok sektörü dolaylı ya da doğrudan etkileyebilir. Çünkü finansal kesimde ortaya çıkan değişimler reel sektöre yansıma potansiyeli sahiptir. Bu çalışma kısa vadeli fon akımlarının konut fiyatları üzerindeki etkilerini Türkiye için araştırmaktadır. Söz konusu araştırma için Granger Nedensellik analizi yöntem olarak kullanılmıştır. Ayrıca araştırma, Türkiye’de konut fiyatlarının önemli ölçüde değişim gösterdiği 2010 ile 2022 yılları arası dönemi ele almaktadır. Analiz sonuçları, 2010 ve 2022 yılları arası dönem için kısa vadeli fon akımlarının, Türkiye’deki konut fiyatları üzerinde önemli etkilerinin olmadığı yönünde bulgular işaret etmektedir. Elde edilen bu bulgu konut sektörü için şaşırtıcı değildir.

Published: January 2023

Bir yardımlaşma yöntemi olan sigorta, İslam dininin emir ve yasaklarına (şer’i kurallara) uygun yapıldığı zaman tekafül yani İslami sigortacılık olarak adlandırılmaktadır. Tekafül, "dayanışma" anlamına gelmekte olup, Arapça kökenli bir kelime olan kefaletten türemiştir. Bu sigorta türü İslam dünyasında çeşitli ülkelerde, farklı yorumlarla uygulanmaktadır. Tekafül sigortacılığını uygulayan şirketler üzerine almış oldukları riskleri aynı reasürans işleminde olduğu gibi retekafül şirketlerine devredebilmektedir. Bu çalışmanın amacı retekafülün reasüranstan ayrılan taraflarını ve son yıllardaki gelişimini incelemek ve belirlemektir. Bir diğer amacı ise mevcut retekafül uygulamasının sigortacılık sektöründe oynadığı rolü vurgulamaktır. Çalışmada retekafül kavramı ve önemi açıklanmış ardından retekafül yöntemlerinin ana hatları çizilerek incelenmiştir. Bu çalışma, sigorta ve reasürans sektörü ile tekafül ve retekafül ile ilgili mevcut literatür ve araştırma eksikliğine katkıda bulunmaktadır.

Authors: Waheed Khawaja bilal , Aljassim Ibrahim Mohammed
Published: January 2023

Objective

To determine outcomes of isolated sigmoid colon thickening detected on computed tomography (CT) and to evaluate certain clinical and CT findings that could help in diagnoses.

Method

This retrospective observational study was performed evaluating CT imaging data of all consecutive adult patients who presented with acute lower abdominal pains in emergency departments and were found to have isolated sigmoid colonic thickening on routine venous phase CT studies, between January 2020 to January 2022. Pre- viously operated cases, known inflammatory bowel disease patients, and those with known sigmoid malignancies were excluded. CT findings regarding the length of the sigmoid segment affected (less or more than 10 cm), mucosal pattern (symmet- ric or asymmetric), presence of diverticula, lymph nodes, and additional features (pericolic abscess or fistula formation, extra-luminal air foci or perforation, local invasion) were documented. Two experienced radiologists made consensus report- ing. Final diagnoses were confirmed on (endoscopic) biopsy results. Patients who did not have endoscopies or were medically treated were excluded. Age, gender, and CT findings were compared with outcomes, and any association was determined by the Chi-squared test.

Results

Out of 30 patients (aged between 20-75 years), the majority were males (n=21) and above 40 years (n=22). Twelve patients had colonic malignancies while 18 had benign findings. Acute presentation, younger patients, and those showing the presence of diver- ticula on CT scans were associated with benign biopsies.

Conclusion

Younger patients who present acutely and show diverticula on CT imaging may have benign causes of sigmoid thickening.

Published: January 2023

Historically, gold, unlike other payment channels, was employed to support trading acquisitions worldwide. We forecast future gold prices based on twenty-two market variables using a machine learning technique. In order to analyze these data, one machine learning approach, random forest regression, was applied. Numerous states have kept and increased their gold reserves while being progressive and rich. In reality, central banks throughout the world keep precious metals like gold on hand to ensure foreign debt service in addition to stabilizing inflation. The primary goal of this research is to anticipate the increase and fall in routine gold rates, which will assist investors in deciding whether to purchase or sell gold. Logistics forecasting is critical to the fiscal performance of an organization. The secondary market is derived by examining the dataset including the previous year's gold price. There is concern that these high prices will not be sustainable and will fall despite the fact that several research has been conducted to examine the relationship between the exchange rate volatility and various economic factors. We employed machine learning through python to forecast financial indicators. Keywords: Gold, machine learning, random forest, python, gold price, ETF, dataset

Here there are two contradictory functions of education which are bothnecessary and it can be shown thatthere are conditions of society under which these can be reconciled. In our study we found that in the general To-do manager applications, tasks are listed in binary form - completed oruncompleted. But contrary to popular belief, people do not complete their task in one go. Instead, they prefer to divide the task in smaller chunks and want their partial completions to be managed by To-do manager. Bytracking out partial task completions of user, we hope to provide a solid base for laying the design of a daily.

FAULT DETECTION AND PROTECTION OF POWER TRANSFORMER USING FUZZY LOGIC
Authors:   Department of Computer and Engineering Sharda University, Greater Noida, UP, India., Dapshima Babagana Ali , Pandey Ankit , Srivastava Arya , Ali Dr. Jabir
Published: January 2023

Power transformer malfunctions cause significant power outages and, as a result, material damage. This critical issue must be resolved. Power transformers must be protected from various fault conditions and power system failure. Fuzzy logic is used in this study to detect and protect power system transformer faults. In the simulation system that diagnoses transformer faults and monitors its operating conditions, the fuzzy logic (FL) toolbox in MATLAB/ SIMULINK software was used. The input variables, current and rate of change of current with time, have been identified as "Error" and "Error-Dot" in the programme. The study's findings show that when the output response is zero, the current in the transformer is normal. This is obtained by injecting [0] and [0] input values into the system, resulting in a response of "6e(-017)," which is close to zero. If the output response is greater than zero, the transformer current is rising above normal and the protection scheme should be notified. This condition is achieved by giving the system input values of [-1.5] and [5] and expecting a response of "+5". If the response is less than zero, the transformer current is less than normal, and the protection scheme should be notified. The study concluded that electrical faults and mechanical failures in power transformers can be quickly identified using Fuzzy logic. Thus, power transformer damage is avoided by controlling relays more effectively and quickly. This has resulted in significant savings in maintenance and repair costs. It is assumed that the study was a success. Keywords: Fuzzy logic, Transformer, fault, Detection, Current, Protection

The Experiences of Graduates with Disabilities Transitioning from Higher Education into Employment
Authors: Cohen Hila , Schreuer Naomi , Sachs Dalia
Published: January 2023

The inclusion of people with disabilities in the labor market strengthens personal development and equal participation in society. Acquiring a higher education in today's modern world increases the likelihood of integrating in the world of work. For people with disabilities, participation in the workforce is strongly dependent on obtaining a higher education. Consequently, enhancing participation in higher education is of great importance. Recognition of the importance of higher education has led to the development of support services for students with disabilities. Nevertheless, success with respect to including students with disabilities in higher education institutions has not yet yielded adequate success with respect to their transition into employment. Students with disabilities rarely acquire preparation to cope with the transition to the world of work. Therefore, the current study examined the experience of students with disabilities as they transitioned from higher education into employment. Method: The study used a qualitative-phenomenological research approach in which 15 graduates with disabilities from five different academic institutions in Israel were interviewed. The interviews were analyzed and encoded in a multi-stage analysis. Results: Analysis of transcripts revealed three main themes: (1) The meaning of the academic studies; (2) The transition into employment; (3) The participants' life journey as people with disabilities. In all three themes, interviewees stressed the development of self-determination skills, such as active conduct, assertiveness, and self-advocacy for integrating into various aspects of life. Discussion: The research findings can be used as a basis for recognizing the factors that influence the integration of graduates with disabilities into employment. A significant research finding is the importance of skills in self-determination to achieving life goals. The skills in self- determination are conceptualized as a mediator between the graduates' self-perceptions of being like everyone else and being different from the mainstream. The research emphasizes the need for intervention in academic settings to support students with disabilities in their transition from higher education into employment, with an emphasis on their development of skills in self- determination. This study raises awareness about occupational therapists' potential to contribute during academic integration and transitions to work

La naturaleza como sujeto de derechos: reflexiones en torno al constitucionalismo andino
Authors: Bustamante Lozano Jhon Jherson
Published: January 2023

La investigación tuvo por objetivo describir los criterios derivados del constitucionalismo andino que permiten determinar que la naturaleza es sujeto de derechos. Con respecto a la metodología, se contempló, en principio, el método cualitativo, pues su objeto se remite a cuestiones dogmáticas y teóricas; ahora, en específico se utilizó la investigación documental; esta permitió organizar, analizar e interpretar información recogida. Ahora bien, el constitucionalismo andino es una corriente constitucional cuyo génesis son las constituciones de Ecuador (2008) y Bolivia (2009). El aporte principal que da al constitucionalismo, en general, es el reconocimiento de los derechos de la naturaleza. Los pilares que sostiene esta corriente constitucional son la filosofía andina, aquí el ser humano no hace abstracciones aislándose de la naturaleza, sino que se integra y desde ahí parte su reflexión. Esta tiene un elemento transversal: el buen vivir, que es un paradigma indígena de vida armoniosa entre los humanos y la naturaleza. La moral andina va a ocuparse de la relación hombre-naturaleza y el biocentrismo postula que la naturaleza tiene una valoración intrínseca.
