What type of an East Asian order does China envision?
Authors:   Research Center for East Asian Studies, Yeon Sangmo
Published: August 2023

China became a second largest economy in the world in 2010. Therefore, it is very likely that China will be a great power which can preside over the international order with the United States, for a economic power tends to produce a military and political power. In the meantime, the questions as to “What type of great power it will be?” have been raised. Common questions of these discussions are whether it will adopt a peaceful foreign policy as a democratic country or a hegemonic and confrontational foreign policy as an authoritarian country. This thesis studied China’s rhetoric and actual diplomatic measures before and after 2010. The study demonstrated that since 2010 its rhetoric and actual diplomatic measures seem to have a tendency of an ‘aggressive or coercive hegemony’. Peaceful rhetoric and actual diplomatic measures which China had showed before 2010 appeared to be temporary and hypocritical ones. Chinese President Xi Jinping began to talk about ‘China’s dream’. ‘China’s dream’ is a ‘great resurrection of Chinese people’. Chinese leaders since Deng Xiaoping have kept a low- profile foreign policy stance by obeying ‘tao guang yang hui’(hide one’s capabilities and bide one’s time), which is Deng’s legacy. However, the Chinese governments began to see itself as a great power and conduct an assertive foreign policy since 2008 when the global financial crisis took place. It launched the ‘Belt and Road Initiative’ and declared the ‘Asian New Security Declaration’ which urged Asian nations to keep Asian security for themselves and began to regard the South China Sea as a China’s core interest. This Chinese aggressive behavior provoked strong repercussions from the United States. Therefore, the U.S. launched a trade war by defining China as a ‘strategic competitor’, which brought about the breakdown of the U.S.-China relations. In summary, China appears to attempt to recover centrality in the world by resurrecting ‘the great tradition of the Chinese nation’ which it once had had. However, it is not still clear what exactly it will look like. Whether China will be a peaceful country or not depends on China’s domestic situation and economic growth, perceptions of China’s leadership, and reactions of the neighboring countries.

Published: August 2023

Introduction: The treatment of diverticulosis symptoms in patients with a history of diverticulitis is a challenge in everyday clinical practice.

Aim: Efficacy assessment of a cyclic, year-long treatment with rifaximin-α in patients with symptomatic uncomplicated diverticular disease (SUDD) and a history of past diverticulitis.

Material and methods: This study is a multicenter, retrospective, observational study involving 48 centers. The study group included patients who reported to the outpatient clinic within a month with SUDD symptoms, who had a history of diverticulitis, and who were given a cyclic rifaximin-α treatment of 2 x 400 mg/day for 7 days and then once a month for 12 months. Epidemiological and demographic data, the course of diverticulosis, the number of inflammation episodes and their diagnoses, complications, symptoms of SUDD, and its treatment were evaluated. The efficacy of rifaximin-α therapy was assessed on a 4-point scale (0 – no symptoms, 3 – severe symptoms) every 3 months, and analyzed: pain, tenderness, bloating, bowel movements, and recurrence of inflammation during the 12-month treatment.

Results: 178 patients (67% women, median age 65 years [34–92]) were included in the study. The average duration of diverticulosis was 6.4 years (3–20), and 59% of patients had more than one episode of diverticulitis during this period. In total, 87% of patients had symptoms of SUDD after or between episodes of diverticulitis. Abdominal pain was the most common symptom (92%). An inflammation episode was diagnosed using imaging in 50.5% of cases, and the rest – based on typical clinical symptoms. As many as 46.2% of patients required hospitalization, and complications were diagnosed in 44% of cases. One hundred and seventy (95%) patients completed the 12-month rifaximin-α therapy. Changes in the severity of pain, abdominal tenderness, diarrhea, constipation, and bloating were assessed every 3 months. After 12 months of treatment with rifaximin-α, there was a statistically significant reduction in the severity of symptoms overall (median from 1.5 [0–3 points] to 0.2; P<0.001) and each symptom evaluated individually. Regardless of the previous diagnostic method of diverticulitis (imaging or typical clinical presentation) or its complications (e.g. perforation, abscess), treatment with rifaximin-α was equally effective.

Conclusions: Cyclic therapy with rifaximin-α is effective in treating SUDD symptoms and in preventing the recurrence of symptoms, also in patients with a history of diverticulitis – regardless of how the diagnosis was made and disease complications. The extended treatment regimen leads to a gradual resolution of symptoms during 12 months of observation. Cyclic use of rifaximin-α is necessary to maintain symptom remission.

Copy number variants (CNVs) have dynamic potential and evolutionary significance like other genetic variants, namely, single nucleotide polymorphisms, InDels, short tandem repeat polymorphisms, inversion variants, etc. Discovering CNVs leads to further speculation that the genomic DNA contains more changes than previously thought and contributes to the phenotypic variation. CNVs are big DNA fragments (> 1 kb) being duplicated or deleted. A bridge between CNVs and phenotypic variations supports CNVs to be utilized in GWAS, which are currently mostly based on SNPs. CNV, which refers to the structural differences, influence gene expression and can be an indicator of numerous traits for improvement. There is a severe dearth of research on CNVs in animals, especially equine. The present study investigates the genomes of the Bhutia Equine breed for genome-wide discovery of CNVs using theAxiom™ Equine Genotyping Array chip for a better understanding of its traits which had been unexplored till date. A total of 619 CNVs from 20 Bhutia equines were identified with the median and average size as 49.394 kb and 114.955 kb, respectively. Total 225 frequent CNVRs with > 1% CNV frequency were identified among them along with singleton type. These CNVRs contained 361 genes in all. The information obtained on genomic variation could be utilized to identify economically advantageous genetic features in Bhutia equine breed.

The fourth current disturbance in our center is higher education quality. It invites various consequences for our lives, industry, and high-level training. This article endeavors to dissect the provokes it gets to high-level training in Indonesia. By utilizing and breaking down the positioning of Indonesian advanced education foundations (HEIs) and corresponding with several understudies, we presume that there are six essential or even progressive changes that Indonesian HEIs should embrace to endure the difficulties of the Fourth Modern Upset. These are unrests in mentalities, general and scholarly interests, educating and learning, educational programs, proficient turn of events, and advanced education administration. The result from this explanatory research displayed no connection between the quantity of understudy and the actual positioning, so one of the six pointers should be reexamined in Indonesia and more centered around how to oversee schooling in Indonesia.

Published: August 2023

To evaluate the current status of fish biodiversity, a study was carried out in the Pailati beel. It was carried out using key informant interviews (KII), focus group discussions (FGD), questionnaire interviews (QI) of fishermen, and secondary data collection. This water body comprised a total of 55 species, 23 families, and 10 orders, with 20% of the species being abundantly available, 40% of the species being commonly available, 29.09% of the species being moderately available, and 10.90% of the species being rarely available. Barbs and minnows (20%) were discovered to be the most common species, followed by carps (16.36%), catfishes (14.36%), and perches (14.55%). The most dominant order was the cypriniformes (38.18%), followed by the perciformes (20%) and the siluriformes (16.36%). Synbranchiformes, Clupeiformes, Osteoglossiformes, Beloniformes, Decapoda, and Anabantiformes made up the remaining seven classes. The values of the indices for Simpson dominance (C), Pielou's evenness (J'), Shannon-Weaver diversity (H), and Margalef's richness (d) in December, January, and February, respectively, were 0.91, 0.443, 3.25, 5.81, 0.94, 0.451, 3.29, and 5.95. Therefore, the results could be used to design and put into action plans that help to maintain the wetlands in a sustainable way.
Türkiye ve Japonya’nın Deprem Gerçekliği: Karşılaştırmalı Bir Analiz
Authors: GÖVER İbrahim Hakan
Published: August 2023

Türkiye’de yaşanan her ciddi deprem sonrası sık sık kamuoyuna Japonya örneği getirilmekte ve yaşanan can kayıpları nedeniyle Türkiye Japonya ile karşılaştırılmaktadır. 2023’te gerçekleşen ve çok sayıda can kaybına yol açan 6 Şubat depremleri sonrasında da aynı konu gündeme gelmiştir. Bunun nedeni her iki ülkenin de bir deprem ülkesi olmasına rağmen, Japonya’nın Türk kamuoyunda büyük depremlerle baş edebilen, deprem farkındalığına sahip bir ülke olarak tanınmasıdır. Ancak, kamuoyunda yapılan bu tür karşılaştırmalar sadece yüzeyseldir ve bilimsel bir anlam ifade etmemektedir. Bu çalışmanın amacı; kamuoyundaki bu algıyı bilimsel bir platforma taşımak, Japonya’nın kamuoyunda oluşturduğu algıda doğruluk payı olup olmadığını özellikle toplumsal ve kültürel etmenleri de dikkate alarak araştırmak ve doğruluk payı varsa bunu nedenleriyle ortaya koymaktır. Çalışmada ülkelerin karşılaştırılması amacıyla depremle ilgili 3 temel parametre belirlenmiştir: a) coğrafi ve beşerî göstergeler, b) yapısal ve yasal göstergeler, c) ekonomik, siyasi ve sosyokültürel göstergeler. Daha sonra ülkeler bu göstergelerdeki verilere göre birbiri ile karşılaştırılmıştır. Yapılan karşılaştırma sonucu Japonya’nın doğal afetlere daha yatkın bir ülke olmasına rağmen depremlerde Türkiye’den daha az kayıp yaşadığı ve bu durumun iki ülke arasındaki toplumsal ve kültürel farklılıklardan kaynaklandığı belirlenmiştir.

Enhancing Voting Security and Efficiency
Authors: Ranjan Nikhil
Published: August 2023

This study explores developing and implementing a novel Electronic Voting Machine (EVM) system integrated with biometric identifiers to enhance voting security and efficiency significantly. Traditionally, voting processes relied on paper ballots, a system fraught with several challenges, including over-voting, the loss or misplacement of ballot papers, environmental harm due to paper consumption, and a lengthy result compilation process. An advanced EVM system is proposed to address these issues, leveraging unique biometric identifiers - facial recognition and fingerprints - for voter authentication and secure vote recording. Our EVM system effectively improves the security against bogus voting and vote repetition, which have been significant concerns in previous voting systems. This robust approach to voter authentication minimizes the likelihood of voting fraud, thus contributing to a more reliable and secure voting process. However, the transition to this advanced EVM system is challenging. The study identifies keyimplications, including the impact on employment due to automation, potential inaccuracies and biases associated with biometric technologies, and vital privacy concerns surrounding using sensitive biometric data. Despite these challenges, the proposed system provides a substantial foundation for future enhancements. Opportunities for further development include the integration of additional biometric identifiers like iris recognition, refining the accuracy of current biometric technologies, and strengthening data privacy measures.

El transistor bipolar de heterounión : física, electrónica y microondas
Authors: López González Juan Miguel
Published: August 2023

El presente libro intenta desarrollar de manera ordenada la teoría física, la teoría electrónica y la teoría de las microondas del transistor bipolar de heterounión. Se explican con detalle los fundamentos y procedimientos que permiten obtener los diferentes modelos del dispositivo en su funcionamiento eléctrico, tanto a baja como a alta frecuencia. Esto permite a estudiosos de nuevos dispositivos electrónicos conocer un camino racional de enfrentarse al conocimiento del dispositivo haciendo una traslación del procedimiento seguido en el libro para el HBT.
La metodología utilizada en este libro es diferente a la habitual en textos del mismo nivel científico-tecnológico, pues en él se deducen gran parte de las ecuaciones matemáticas presentadas. Este método permite al lector comprender los conocimientos y métodos presentados sin necesidad de consultar simultáneamente otras referencias.
La elaboración de problemas cortos sobre conceptos puntuales es el procedimiento habitual de trabajo en la mayoría de los libros de texto. Este método de estudio no asegura la capacidad de relacionar los conceptos, más aún cuando la formulación matemática de los mismos no ha sido debidamente justificada o comprendida. Este libro es novedoso en el método de trabajo, pues al justificar matemáticamente la mayoría de los avances realizados, permite al lector aplicarlos a cualquier transistor bipolar de heterounión (el último capítulo del libro se dedica completamente al estudio ordenado, cuantitativo y cualitativo de un transistor bipolar de heterounión real).

Ergonomía. Vol. 3, Diseño de puestos de trabajo
Authors: Rodríguez Mondelo Pedro Manuel , Gregori Torada Enrique , Blasco Font de Rubinat Jaime , Barrau Pedro
Published: August 2023

Un puesto de trabajo es el lugar donde una o varias personas deben desarrollar cotidianamente una actividad regulada, fiscalizada y controlada, al menos durante una tercera parte del día. Si el puesto de trabajo es incómodo, monótono, agotador, desagradable, nocivo o peligroso, puede llegar a compararse con una estrecha jaula que resta calidad a nuestro trabajo y a nuestras vidas, nos enferma y hasta nos puede matar, y que abandonaremos a la primera oportunidad. En cambio, si el puesto de trabajo es seguro, cómodo, estimulante y agradable, además de generar bienes materiales y desarrollar nuestra productividad y creatividad, nos proporciona satisfacción física y espiritual. Diseñar puestos de trabajo es una necesidad económica y una agradable obligación moral del sentido común.

In recent years, online social networks (OSNs) have become a huge used platform for sharing activities, opinions, and advertisements. Spam content is considered one of the biggest threats in social networks. Spammers exploit OSNs for falsifying content as part of phishing, such as sharing forged advertisements, selling forged products, or sharing sexual words. Therefore, machine learning (ML) and deep learning (DL) techniques are the best methods for detecting phishing attacks and minimize their risk. This paper provides an overview of prior studies of OSNs spam detection modeling based on ML and DL techniques. The research papers are classified into three categories: the features used for prediction, the dataset size corresponding language used, real-time based applications, and machine learning or deep learning techniques. Challenges and opportunities in phishing attacks prediction using ML and DL techniques are also concluded in our study.
P. D. Ouspensky’s First Revision of Tertium Organum
Authors: Azize Joseph ,   Academic Publishing
Published: August 2023

When P. D. Ouspensky (1878–1947) is noted today, it is generally as a quondam pupil of G. I. Gurdjieff (c.1866–1949), and the author of In Search of the Miraculous, an account of his time with Gurdjieff. Ouspensky had a considerable reputation in Russian esoteric circles before he had met Gurdjieff, and it is sometimes asserted that Ouspensky’s standing as an independent thinker has been underestimated. The English translation of his book Tertium Organum has been cited as evidence that Ouspensky had already anticipated some of Gurdjieff’s leading ideas. However, a comparison of the 1911 Russian-language edition with the 1920 English translation of the 1916 Russian revision of Tertium Organum establishes that the 1911 original lacked key ideas found in later editions, most of which are distinctively Gurdjieff’s. This shows the extent of Ouspensky’s debt to Gurdjieff, and casts a different light on the relationship between Gurdjieff and Ouspensky; namely, that there was more collaboration than previously known, and that Ouspensky’s account of his agreement with Gurdjieff about committing Gurdjieff’s ideas to writing, was tendentious, if not misleading.

The short-haul flights have higher emission values than medium or long-haul flights when emissions per distance are considered. In this study, the potential to reduce greenhouse gas emissions by replacing short-haul flights which carried out by a narrow-body commercial aircraft from/to Konya City in Turkey with regional jets or high-speed trains (HSRs) has been investigated. The flight trajectory is selected from Konya Airport to İstanbul Sabiha Gökçen Airport, and that trajectory is a frequently performed domestic flight between Konya and İstanbul. The IMPACT platform is used for the calculation of fuel burn and gas emissions. According to the results, traveling with regional jets or high-speed trains from/to Konya City which is the most 15th polluted city in Europe, provides advantages in terms of environmental impact. Traveling with HSR which is the best traveling option in this study, provides approximately 3.3 times more green travel than the currently used narrow-body passenger aircraft between Konya and İstanbul. In addition, this mode of transportation can become more environmentally friendly by using renewable energy sources to produce its electricity needs. It is expected that this study will serve as a guide for airline and high-speed rail operators and regulators to determine the most environmentally efficient travel options based on fuel burn and emission parameters.

The recent increase in renewable energy generation can balance consumption and reduce carbon emissions. With battery energy storage optimizing supply and demand, it is more important than ever to manage charge control to the benefit of all stakeholders. In this paper, the developed and proposed energy management control methods based on the technical operating criteria of battery energy storage (BESS) and considering self-consumption rate (SCR), self-supply rate (SSR) and curtailment rate are compared in terms of environmental index and economics for daily and annual demand profiles for various household prosumer demand profiles in Istanbul and Antalya. Considering the supply-demand matching based on demand profile, feed-in damping, fixed feed-in, schedule mode, schedule mode with constant charging power and self-consumption control methods are proposed for optimum operation for each prosumer profile. The results show that feed-in damping and fixed feed-in methods can reduce household prosumer costs by up to 22.3% in the daily analysis. Moreover, similar control methods can increase SCR by up to 29.5% and reduce costs by up to 10.62% for higher irradiances in the annual analysis. Proper management of BESS charge control can facilitate sustainable development goals by assisting plans of many stakeholders.

Numerical methods are commonly used for analyzing combustion characteristics. Besides, they provide an opportunity to predict emissions of an engine. In this paper, the conversion of a single-cylinder diesel engine to HCCI combustion model is investigated with AVL Boost v2021R2. The model was used to simulate the power, emission, bsfc value. In-cylinder pressure results also are obtained from the model. Verification of the model is conducted with experimental data from the literature. The differentiation between the numerical and experimental results remained below 8.9% for the power, below 6.62% for bsfc. In addition to this, the model gave maximum pressure values with an accuracy of ± 1%, and maximum HRR values with an accuracy of ± 2%. Maximum HRR values and in-cylinder pressure curves for 1200-2400 rpm were obtained with acceptable accuracy. Besides, the operating range of an HCCI engine fueled with n-heptane was investigated using a zero-dimensional single-zone model with reduced fuel chemistry. The compression ratio and inlet air temperature effect on HCCI combustion were analyzed. The increasing the air inlet temperature to 40oC from 20oC, increases the lowest air-fuel ratio about 6.6% which the engine can operate without entering the knock zone, at 17.5 CR at 1200rpm.
Effect of oxy-colorless distributed combustion of methane flame behaviour in a premixed gas turbine burner
Authors: Alabaş Buğrahan , Türkkahraman Zeliha
Published: August 2023

NOX emissions and flame characteristics in gas turbine burners are a current issue. Different combustion methods are tested for the solution of NOX emissions. One of these methods is oxy-colorless distributed combustion. In this method, CO2 is used as a diluent instead of N2 gas in the air. In this way, nitrogen does not enter the combustion chamber and theoretically NOX emissions are planned to be zero. In this study, a premixed and swirl assisted gas turbine combustion chamber used experimentally was verified numerically. Analyzes were carried out by keeping 3 kW thermal power, 1 swirl ratio and 0.7 equivalence ratios constant. The oxy-colorless distributed combustion method was applied to the pure methane flame at different O2/CO2 ratios. Analyzes were carried out with the O2 ratio of 26%, 21%, 19%, 17% and 15% by volume. The results showed that the colorless distributed combustion conditions were achieved as the CO2 ratio increased. Thanks to the oxy-colorless distributed combustion method, almost zero NOX emissions have been achieved. In addition, as the O2 ratio in the oxidizer mixture decreased, a significant decrease in the flame temperature was detected. Thanks to this study, the effect of oxy-colorless distributed combustion conditions in a premixed and swirl supported combustion chamber was investigated.

In this paper, the method of the inverse spectral problems are used to integrate the nonlinear modified Korteweg-de Vries equation with finite density in the class of periodic functions. The solvability of the Cauchy problem for an infinite system of Dubrovin differential equations in the class of five-fold continuously differentiable periodic functions is proved. It is shown that the sum of a uniformly convergent functional series constructed by solving the system of Dubrovin equations and the first trace formula satisfies the mKdV equations with finite density.
