Penerimaan Pengungsi Afghanistan oleh Korea Selatan pada Tahun 2021 Melalui Operation Miracle
Authors: Ramadani Layli , Afriani Sinulingga Anita , Cory Silvi
Published: October 2024

South Korea is one of the countries that ratified the 1951 Refugee Convention in 1992 and implemented it into domestic regulations in 2013. Even though it has been ratified and implemented, the rate of acceptance of refugees in South Korea is very low. In 2020 the refugee acceptance rate is less than two percent of the number of incoming asylum applications. South Korea appears to have implemented a policy that is closed to refugees as seen from one of the policies for returning refugees directly which is not in line with the provisions of the 1951 Refugee Convention. But in 2021, the government adopt a more hospitable policy towards refugees originating from Afghanistan. This study aims to explain the factors that influence the acceptance of Afghan refugees by South Korea in 2021. This research is analyzed using the concept of foreign policy change by Spyros Blavoukos and Dimitris Bourantonis. This study used a qualitative research methodology and a descriptive-analytical type of research. Based on the concept used, the first factor affecting the acceptance of Afghan refugees by South Korea in 2021 is the domestic structural parameter influenced by the power of progressive parties in the legislature and executive and the existence of a network of advocacy groups. Second, international structural parameters influenced by the United States' encouragement of South Korea, and the role of the UNHCR in encouraging the acceptance of Afghan refugees.
China's Motivation to Improve Bilateral Relations with South Korea After the Polemic of THAAD (Terminal High Altitude Area Defense)
Authors: Yusra Afdhal , Yusra Muhammad , Austin Diah Anggraini
Published: October 2024

North Korea's aggressiveness in launching ballistic missiles has threatened the security stability of East Asia. As a state under threat, South Korea formed a joint security partnership with the United States through the deployment of THAAD in 2016. However, China has opposed it by arguing that THAAD would threaten domestic and regional security stability. As a result, China's rejection led to the presence of the phenomenon of economic retaliation which resulted in a decrease in the value of South Korea-China bilateral trade and distrust. Nevertheless, after negotiations, the two countries decided to improve bilateral relations in 2017. This paper aims to determine China's motivation in improving bilateral relations with South Korea as a foreign policy decision after rejecting the deployment of THAAD under the guise of threatening to trigger bilateral polemics. This research will be analyzed through qualitative methods with the conceptual framework of foreign policy determinants by Shannon L. Blanton and Charles Kegley. In this conceptual framework, there are five determinants that influence foreign policy decision making namely military capabilities, economic conditions, type of government, global distributions of power, and geopolitical factors. Furthermore, Blanton & Kegley's conceptual framework identifies that each of these determinants influenced China's motivation to improving bilateral relations with South Korea after the THAAD polemic.
Unscented Trajectory Optimization
Authors: Ross Isaac M. , Proulx Ronald J. , Karpenko Mark
Published: October 2024

In a nutshell, unscented trajectory optimization is the generation of optimal trajectories through the use of an unscented transform. Although unscented trajectory optimization was introduced by the authors about a decade ago, it is reintroduced in this paper as a special instantiation of tychastic optimal control theory. Tychastic optimal control theory (from Tyche, the Greek goddess of chance) avoids the use of a Brownian motion and the resulting Itô calculus even though it uses random variables across the entire spectrum of a problem formulation. This approach circumvents the enormous technical and numerical challenges associated with stochastic trajectory optimization. Furthermore, it is shown how a tychastic optimal control problem that involves nonlinear transformations of the expectation operator can be quickly instantiated using the unscented transform. These nonlinear transformations are particularly useful in managing trajectory dispersions, be they associated with path constraints or targeted values of final-time conditions. This paper also presents a systematic and rapid process for formulating and computing the most desirable tychastic trajectory using the unscented transform. Numerical examples are used to illustrate how unscented trajectory optimization may be used for risk reduction and mission recovery caused by uncertainties and failures.

Authors: Wibowo Yoga Herlambang W.R. , Novrinda Riza , Abdullah Muhammad
Published: October 2024

Pengelolaan pertambangan memerlukan identifikasi bahaya yang efektif sebagai dasar untuk pembuatan standar operasional prosedur (SOP). Namun, upaya identifikasi bahaya saat ini belum diterapkan dengan baik, terutama karena kurangnya pemahaman tentang pentingnya identifikasi bahaya dalam berbagai kegiatan pertambangan, yang sering kali mengakibatkan ketergantungan pada dokumen tertulis tanpa visualisasi yang memadai. Untuk mengatasi hal ini, diusulkan integrasi kendaraan udara tanpa awak (UAV) untuk pemetaan data, yang memungkinkan visualisasi area berbahaya yang lebih baik. Area yang teridentifikasi dikategorikan ke dalam zona risiko: merah (sangat tinggi), oranye (tinggi), kuning (sedang), dan hijau (rendah). Penelitian ini berfokus pada lokasi berbahaya yaitu pada jalan angkut dan kolam pengendapan, serta menilai risiko keselamatan dan lingkungan. Langkah pengendalian risiko diklasifikasikan sebagai dapat dikendalikan atau tidak dapat dikendalikan, dengan hasil pemetaan mencerminkan penilaian risiko awal, saat ini, dan akhir dalam rentang waktu 3-4 bulan. Temuan ini menekankan pentingnya pemodelan visual dan atribut pengendalian risiko, menawarkan wawasan berharga bagi pemangku kepentingan untuk mengurangi risiko kecelakaan pertambangan dan insiden lingkungan.
Absolute Zeta functions and periodicity of quantum walks on cycles
Authors: Akahori Jiro , Konno Norio , Sato Iwao , Tamura Yuma
Published: October 2024

The quantum walk is a quantum counterpart of the classical random walk. On the other hand, absolute zeta functions can be considered as zeta functions over $\mathbf{F}_1$. This study presents a connection between quantum walks and absolute zeta functions. In this paper, we focus on Hadamard walks and $3$-state Grover walks on cycle graphs. The Hadamard walks and the Grover walks are typical models of the quantum walks. We consider the periods and zeta functions of such quantum walks. Moreover, we derive the explicit forms of the absolute zeta functions of corresponding zeta functions. Also, it is shown that our zeta functions of quantum walks are absolute automorphic forms.
Linear circuit synthesis using weighted Steiner trees
Authors: Gavrielov Michele  Nir , Ivrii Alexander , Garion Shelly
Published: October 2024

CNOT circuits are a common building block of general quantum circuits. The problem of synthesizing and optimizing such circuits has received a lot of attention in the quantum computing literature. This problem is especially challenging for quantum devices with restricted connectivity, where two-qubit gates can only be placed between adjacent qubits. The state-of-the-art algorithms for optimizing the number of CNOT gates are heuristic algorithms that are based on Gaussian elimination and that use Steiner trees to connect between different subsets of qubits. In this article, we suggest considering \emph{weighted} Steiner trees, and we present a simple low-cost heuristic to compute weights. The simulated evaluation shows that the suggested heuristic is almost always beneficial and reduces the number of CNOT gates by up to 10%.
Quantum state synthesis: relation with decision complexity classes and impossibility of error reduction
Authors: Delavenne Hugo , Gall François Le
Published: October 2024

This work investigates the relationships between quantum state synthesis complexity classes (a recent concept in computational complexity that focuses on the complexity of preparing quantum states) and traditional decision complexity classes. We especially investigate the role of the \emph{synthesis error parameter}, which characterizes the quality of the synthesis in quantum state synthesis complexity classes.We first show that in the high synthesis error regime, collapse of synthesis classes implies collapse of the equivalent decision classes. For more reasonable synthesis error, we then show a similar relationships for $\BQP$ and $\QCMA$. Finally, we show that for quantum state synthesis classes it is in general impossible to improve the quality of the synthesis: unlike the completeness and soundness parameters (which can be improved via repetition), the synthesis error cannot be reduced, even with arbitrary computational power.
The necessary and sufficient condition for the uniqueness of Schmidt decomposition and the necessary condition for the maximal von Neumann entanglement entropy
Authors: Li Dafa , Cheng Maggie , Li Xiangrong , Li Shuwany
Published: October 2024

Schmidt decomposition (SD) has been proven to be an important tool in quantum information and computation. Ac{\' i}n et al. proposed the SD for three qubits, but in the meanwhile, they indicated that it is possible to have two different SDs for the same state. The more challenging quest of finding the sufficient and necessary condition for the uniqueness of SD has never been undertaken. In this paper, we propose a necessary and sufficient condition for the uniqueness of SD for three qubits. By examining the condition, one can tell what state has one SD and what state has two SDs without actually performing the Schmidt decomposition. We investigate the relation between the uniqueness of SD and the von Neumann entanglement entropy (vNEE). To this end, we prove that any state having the maximal vNEE $S(\rho _{x})=\ln 2$, $ x=A, B,$ or $C$ must have a unique SD. %Therefore, we should choose a state having a unique SD for its maximal vNEE for quantum information theory. This means if a state has two SDs, then the state does not have the maximal vNEE. Therefore, we should not choose a state having two SDs for its maximal vNEE for quantum information theory. In this paper, we also give all the SD states that have the maximal vNEE and a unique SD, as well as all the SD states that have a unique SD.

This article describes the approach to the petrous pyramid developed at National Medical Research Center of Otorhinolaryngology, namely an endoscopy – microscopy-guided modified trans-channel infra-promontorium approach with internal carotid artery retraction maneuver in patients with lesions of the petrous pyramid but with preserved hearing. A clinical report describing the apical cholesteatoma of the petrous pyramid and the use of this approach are presented. Anatomical and functional features after the surgery are also described. The purpose of this paper is advancing of the surgical approach to the petrous pyramid with the possibility of hearing preservation. The results of surgical treatment in lesions of the petrous pyramid were evaluated in the immediate and distant periods. The functions of facial mimic muscles were evaluated immediately after the surgery, in 6 months, and in one year. The functions of facial mimic muscles remained at the baseline level during the whole follow-up period. The pure tone audiogram demonstrated the preserved hearing function in the postoperative period. Complete elimination of the pathological process was achieved in all cases (n=15); according to the MRI of the temporal bones, no relapses occurred in a year. The surgical approach proposed for patients with the lesions of the petrous pyramid enables complete removal of the pathological process from the petrous pyramid with the preservation of hearing and facial functions, based on the subjective examinations (audiometry, facial function diagnosis) and radiology (CT and MRI of temporal bones) at the preoperative stage.
Modern problems of bronchial tuberculosis in the world and the Russian Federation: A review
Authors: Chumovatov Nikita V. , Polushkina Ekaterina G. , Chernykh Natalya A. , Komissarova Oksana G.
Published: October 2024

In the Russian Federation there is a positive trend in reducing the incidence of tuberculosis. However, there is a tendency to increase the prevalence of tuberculosis in the bronchi. According to foreign authors, the prevalence of bronchial tuberculosis ranges from 10% to 40%. There are no official statistics on the incidence of bronchial tuberculosis in the Russian Federation. The main contingent of bronchial tuberculosis lesions are young non-smoking women. At the same time, the most common target is the left main bronchus. Currently, no additional methods have been developed in the scheme of specific treatment of patients with pulmonary tuberculosis complicated by bronchial tuberculosis. It is important to understand that the eradication of MBT after an effective course of chemotherapy does not prevent the formation of cicatricial bronchial stenosis. It is also important to note that bacterial excretion in patients with bronchial tuberculosis is much more common than in patients with a comparable process in the lungs, but without bronchial damage. Consequently, tuberculosis of the trachea and bronchi has not only clinical, but also great epidemiological significance.

Published: October 2024

This study examines the strategies on invitation speech act in Turkish based on the speech act theory in pragmatics which fundamentally positions that when people use language they actually perform a kind of action. The purpose of the present study is to investigate the strategies employed on invitation speech act by native speakers of Turkish. To accomplish the goal, an online Written Discourse Completion Task (DCT) was employed with an aim to delineate the strategies Turkish speakers use while inviting. Another method was examining several different Turkish television series. Following the implication of the quantitative technique of conversation analysis, the utterances in data from invitation acts were analyzed in terms of the patterns of the semantic formulas categorized in the taxonomy by Suzuki (2009). The findings of the study revealed that invitation acts used in Turkish have their unique patterns. Direct invitations (84.90%) were more frequent than indirect ones (15.09%). Moreover, the most predominant type of head act was declarative (40.33%) and query on hearer’s plan (17.64%) had the highest frequency among preparatory acts. The most common supportive move was description of event by 48.44% of Turkish invitations.
Investigation of Dynamic Balance, Limb Asymmetry and Flexibility in Jiu-Jitsu Athletes: A Preliminary Exploratory Study

This preliminary exploratory study is the first to thoroughly examine dynamic balance, inter-limb asymmetry, and flexibility in jiu-jitsu athletes, focusing on differences by fighting style, competition level, gender, and limb dominance. A total of 25 jiu-jitsu fighters participated in this cross-sectional study, which used repeated measures to ensure the reliability of the findings. Participants underwent measurements for limb lengths and were assessed for dynamic balance using the Lower and Upper Quarter Y Balance Test (LQYBT and UQYBT) and for flexibility with the Sit and Reach Test (SR). The analysis included evaluating the reliability of these tests, as well as comparing outcomes based on gender, fighting styles, competition levels, and limb dominance. The results showed that the LQYBT and UQYBT tests were reliable (ICC=0.74–0.93). There were no significant differences in dynamic balance and flexibility between different fighting styles. No significant differences were found in balance tests between the dominant and non-dominant limbs, but there were notable inter-limb asymmetries in certain measures.

Overweight and obesity are widespread worldwide among children of all age groups, and the prevalence among preschool children has been steadily increasing over the past twenty years. The aim of was to determine the prevalence of overweight and obesity of preschool children in Serbia based on the recommendations given by the WHO (World Health Organization) and the CDC (Centers for Disease Control and Prevention). The sample of respondents consisted of children from the preschool institution “Our Child” (serb. Naše dete) from Vranje, Serbia. A total of 380 children participated, of which 195 were boys (51.3%) and 185 were girls (48.7%). The age of the child ranged from 2 to 7 years, that is, from 26 to 84 months. In order to determine the weight status, the children’s body weight and height were measured, on the basis of which the Body Mass Index (BMI) was calculated. The obtained BMI values were interpreted based on the recommendations given by the WHO and the recommendations given by the CDC. Research results based on the WHO recommendations showed that 11.1% of the total number of children are overweight and 11.8% are obese, while based on the CDC recommendations, 11.8% of the total number of children are overweight and 7.9% are obese. Also, the research showed that there is no difference in the weight status categories between boys and girls. However, the results show that the proportions of overweight and obese children obtained using the WHO recommendations differ significantly from the proportions of overweight and obese children obtained using the CDC recommendations. High percentages of overweight and obesity among preschool children in Vranje require adequate measures to be taken in order to stop and reduce their growth.

Bas karakterli bakır çalgılar ailesinin bir üyesi olan “cimbasso”, valf sisteminin bulunması ile ortaya çıkmış çalgılardandır. Kökeni, 16. yüzyılda ortaya çıkmış olan “serpent” adındaki çalgıya kadar uzanmaktadır. “S” şeklinde ahşap bir gövdeye sahip olmasına rağmen bakır çalgılar ailesinin bir üyesi olarak sınıflandırılan serpent, 18. yüzyılın sonlarına gelindiğinde yapısal olarak büyük bir değişikliğe uğramıştır. Farklı isim ve modellerde üretilen bu çalgılar askeri ve sivil bandolarda, opera ve senfoni orkestralarında aktif olarak kullanılmıştır. Her bir çalgı bir önceki modelin sorunlarını gidermeyi amaçlamış, yenilenmekte ve genişlemekte olan orkestralardaki bas seslerine çözüm odaklı üretilmişlerdir. 19. yüzyıl İtalya’sında bas karakterli bakır çalgıları tanımlamak için kullanılan cimbasso adı, Verdi’nin 1881 yılındaki girişimleri ile günümüzde sadece bir çalgıyı tanımlayan bir terime dönüşmüştür. Nitel araştırma yöntemi ile hazırlanan bu çalışmada, cimbasso olarak adlandırılan çalgıların kökenleri, yapısal özellikleri ve kullanım alanları incelenmiş, modern cimbasso çalgısının nasıl ortaya çıktığı ele alınmıştır.

Published: October 2024

Since ancient times, India has employed the organic farming technique, which is primarily concerned with producing agricultural products that are sustainable in a clean, unpolluted environment. In order to achieve the necessary agricultural production for human consumption, organic production methods make use of natural resources, maintaining the ecosystem and ecology alive and well. Using naturally occurring resources as inputs, such as organic wastes, farm, animal, and crop wastes, aquatic wastes, other biological materials, and beneficial microbes, is the environmental focus of organic production. Biofertilizers and biocontrol agents are used to release nutrients into crops and shield them from insect pests and diseases in order to increase agricultural productivity. It is imperative that farms move to organic practices. India, a nation that depends heavily on agriculture, must take measures to address the issue of its rapidly expanding population.Although there has been a noticeable movement in people's knowledge of organic food, it appears to be quite gradual. The cultivation of organic crops using the organic farming technique is gaining steam on a global scale. To achieve sustained food, livelihood, and environmental security, a range of alternatives to chemical intensive agriculture must be developed. The present study is an Exploratory cum Descriptive Research in nature with a sample size of 200 customers and various statistical tools such as frequency distribution, percentage, arithmetic mean and general linear Univariate model used. The respondents from different age group, different qualifications and others agreed that there should be an immediate improvement in the product accessibility in the market and the government as well as the producers, should play a key role in it. The study concludes that Organic product’s Market availability needs to improve from Govt. as well as producers both.
The Role of the European Parliament in the Development of the EU-USA Transatlantic Relations
Authors: Sülün Dilara
Published: October 2024

This article explores the scope and evolution of the European transatlantic policy with the United States of America (USA). Our research questions are related to the number and content of the texts adopted by the European Parliament (EP) and the role of the EP and its Committees in shaping the European transatlantic policies. We examine which are the committees that lead and guide the EP transatlantic conclusions. Within this context, this research paper highlights the substance of the European Union (EU) and the USA relations over the last 25 years and the major areas in which the EU cooperates with the USA. We have built our research on the European Parliament since it has legislative authority in shaping and guiding EU’s external policy. Therefore, our study brings a new perspective to the current literature on transatlantic relations by assessing the EU-USA relations from the EP conclusions and adopted legal texts. A document and policy analysis are conducted between 1999 and 2024, to assess each of the last five Parliamentary Terms and through the entire current EU laws in force. We conclude that despite studies asserting the weakening of the EU-USA relations, EU’s relations have been consistent since 1999 and even increasing in the last decade, from technical and legal achievement, based on the quantitative and contentive analysis of our research.

Translation Strategies of English Passive Constructions into Arabic: An Analysis of Google Translation Engine Produced Translations Using House’s TQA Model
Authors: Al-Qahtani Nourah , Alhedayani Rukayah
Published: October 2024

This study explores the translation of English passive constructions into Arabic, focusing on the prevalent translation shifts and the preservation of the source functions within this process. Utilizing a qualitative methodology, it analyzes passive constructions from an English economic-political article based on House’s (2015) Translation Quality Assessment model. It reviews all passive participles classifying them into verbal and adjectival ones. The research aims to understand how these translation shifts cater to the syntactic and semantic needs of the Arabic language, particularly how machine translation tools like Google Translation engine handle these transformations. Data collected include various English passive constructions and their Arabic translations, providing a foundation for assessing either their adherence to the target language’s norms and preferences or to the literal approach that may lead to affect such preferences and norms. Key findings reveal how Google Translation engine tends to translate according to Arabic norms and produce a natural translation while preserving the source functions. The five translation strategies used by Google Translate when translating passive constructions from English to Arabic in economic-political texts are: 1) adjectival phrases, 2) active structures, 3) passive structures with internal vowel changes, 4) verbless structures with verbal nouns, and 5) verbal phrases with 'tamma'. However, the influence of such an approach may lead to manipulating the source function, which may lead to misunderstandings or to unbalanced power relations.
