Korean DPRK CuiShizhen Chinesephonology “qualitypositive”
Authors:   The Society For Chinese Humanities In Korea, Zhang Hui
Published: December 2022

During the Korean Dynasty (1391-1910), the “quality officials” played an important role in the spread of Chinese to the Korean peninsula, and played an important role in the history of Sino Korean language and cultural exchanges. Cui Shizhen went to China for many times as a “quality official” to “improve Chinese”. As an important practitioner of “improve Chinese” activities, Cui Shizhen has played a positive role in promoting Chinese teaching and research in North Korea, and has a far-reaching impact. The research on Cui Shizhen's achievements in Sinology from the perspective of “quality and integrity” is of great value to the research on the history of Chinese phonology in East Asia and the comparative linguistics of East Asian history from the perspective of sinology abroad. The ancient rhyme script on the Korean Peninsula is included as an important part of the study of the history of Chinese rhyme script, which provides a new basis for promoting the collation and study of the ancient rhyme script on the Korean Peninsula in China, as well as the study of the history of regional language relations in Northeast Asia from the perspective of “regional countries”, the study of the history of the spread of Chinese culture outside the region, and the study of intangible cultural heritage between China and the Korean Peninsula. Cui Shizhen also presented Chinese books to the King of Korea in the above “True Records”. This shows that if the “quality official” is taken as a breakthrough, it will find a new support for the study of the origin and development of the Sino Korean (Korean) language and culture. The ancient rhyme script on the Korean Peninsula is an important part of the study of the history of rhyme script on China and the Korean Peninsula. It carries the excellent traditional culture of China and the Korean Peninsula, and reflects the diachronic evolution of language, literature, culture, ideology, education and other fields. “Quality officials” play an important role in the communication and acceptance of the above fields.

Published: December 2022

The character “𠂤(dui)”, “■” on oracle bone inscriptions and “𠂤(dui)” “■” “師(shi)”acle bone and bronze inscriptions can be also named , referring to people living in groups; or it can be called as “次(ci)”, referring to a military camp. Jinhousu Chime plays an important role in the research on the Western Zhou Dynasty bronze inscriptions. Based on three usages of the character “𠂤(dui)” as “𠂤” “■” “師” in Jinhousu Chime, this article analyses the character “𠂤” in “六𠂤(liu dui)” and “八𠂤(ba dui)” which has been always read as “師” in the Western Zhou Dynasty bronze inscriptions. Thus, it is found that there are 12 cases of the word “𠂤” in the Western Zhou Dynasty bronze inscriptions used as the meaning of “堆(dui)”. When it is used as “堆”, the verb “司(si)” or “正(zheng)” is often used before the word; In 7 cases, it used as the meaning of “■(次)”. When it used as “次”, the verb “省(sheng)” or the preposition “在(zai)” and “于(yu)” are often used before the word “次”; In 7 cases, it is used as “師”. When it is used as “師”, the verb “率(shuai)” and “命(ming)” or the preposition “以(yi)” are often used before the word “師”. This article provides an important clue for the study of bronze inscriptions through the comprehensive classification of the usage of “𠂤” in the inscriptions of Jinhousu Chime and the usage of “𠂤” in the bronze inscriptions of the Western Zhou Dynasty.

A Study on Description of A famous sword revealed in 『Wu-Yue Chunqiu』 and 『Yue Jue Shu』
Authors:   The Society For Chinese Humanities In Korea, KIM YOUNG-SIK
Published: December 2022

『Wu-Yue Chunqiu』 and 『Yue Jue Shu』 are regional historical and local books that fully reflect the history of the Wu and Yue countries located in southern China during the Eastern - Han Dynasty, as well as local products and characteristics. There are several noteworthy narratives in these books, but the one on the famous sword is particularly outstanding and moving. Regarding the description of the famous sword in these two books, this paper analyzed the descriptions in the process of making the famous sword, ritual, performance, use, and shape, and sought their meaning. The moving and literary description of the famous sword in various places is not only meaningful to the story itself, but also provided a framework to look into the trends and trends of consciousness in the southern society at the time through the description of the famous sword. What we can know from the descriptions of the famous sword is that the narratives of the famous sword made a great contribution to the development of Chinese epic literature, and it is also possible to evaluate 『Wu-Yue Chunqiu』, which describes the famous sword in various places, as a book approaching literature of fiction.
A study on the use of the discourse marker “Ranhou” by non-native speakers: Take English and Korean native speakers as an example
Authors:   The Society For Chinese Humanities In Korea, . .
Published: December 2022

This paper takes native English and Korean speakers as the research objects, and examines their use of the discourse marker “Ranhou” in Chinese communication from the aspects of distribution and function by means of statistical and comparative analysis. On this basis, find out the factors that form and affect the above characteristics. After investigation, we found that both native and non-native speakers tend to use “Ranhou” as a discourse marker in long-turn personal declarative Chinese communication. However, non-native speakers' psychological dependence on “Ranhou” is far less strong than that of Chinese native speakers, so the frequency of use is much lower than that of native speakers. Functionally, the discourse marker “Ranhou” works at both the discourse and interpersonal levels. In the corpus of native speakers and non-native speakers, the specific functional performance of “Ranhou” has both common features and individual differences. We believe that the above differences are related to the influence of the communicator's language ability.

Instrumento: Proceso de Visualización Geométrica en Grado Transición
Authors: Usaquén Beltrán Sandra Milena , Frausto Mireya
Published: December 2022

La investigación pretendió validar un instrumento que permitiera identificar el proceso de visualización geométrica en el grado transición con 25 niños de 5 y 6 años, de la Institución Educativa Distrital Álvaro Gómez Hurtado, Bogotá, Colombia. Para lograr este objetivo se diseñaron actividades, las cuales fueron aprobadas por un experto en el tema. La metodología se enmarcó en una investigación cualitativa de corte descriptivo, con el fin de apreciar la aceptación y comprensión por parte de los niños de las tareas propuestas en cuanto a las etapas de la visualización geométrica, desde la perspectiva de Duval quien realiza una clasificación de las maneras de ver en geometría, en función del papel de las figuras en las actividades geométricas que se proponen a los estudiantes. Como principal resultado se encontró que los niños lograron comprender las actividades propuestas en las diferentes entradas clásicas de la geometría (Botánico, Agrimensor, Constructor e Inventor). Lo cual indica que es un instrumento útil para otras investigaciones cuyos objetivos se relacionen con los procesos de visualización geométrica. De igual manera, los resultados obtenidos con el instrumento permiten inferir que sí se puede llevar al aula actividades que además de ser significativas y motivantes para ellos, permiten realizar procesos donde a través de diferentes fases los niños logran desarrollar competencias en su pensamiento geométrico y por ende espacial. Por lo anterior, el proceso de visualización en geometría debe abordarse desrede edades tempranas, ya que esto facilita el desarrollo de habilidades que serán el andamiaje en las competencias para los cursos superiores y que conllevaría a mejorar los resultados académicos en todos los componentes de área de matemáticas. Finalmente, con la investigación se hace una invitación a los docentes de los diferentes niveles de escolaridad a que se tenga una mirada diferente frente a los procesos que se deben potencializar en los niños desde el preescolar, específicamente en el campo de la geometría. Se espera que el estudio presentado con la validación del instrumento sirva como material de apoyo en la realización de nuevas investigaciones que aporten al conocimiento geométrico.

Published: December 2022

El objetivo de la investigación fue determinar la prevalencia de complicaciones postoperatorias de la exodoncia y su tratamiento en pacientes atendidos en la clínica de Patología y Diagnóstico de la Facultad de Odontología de Corrientes, Argentina. Se realizó un estudio descriptivo, observacional, transversal y prospectivo en la clínica de Patología y Diagnóstico, utilizando un muestreo no probabilístico por conveniencia: se seleccionaron los pacientes que concurrieron a la clínica B de Patología y Diagnóstico para realizarse exodoncias y presentaron complicaciones postoperatorias después de la misma, desde agosto 2021 a junio 2022. Las variables estudiadas fueron: edad, sexo, grupo dentario (incisivo, canino, premolar, molar), localización según el maxilar, hábito de fumar, si recibió medicación pre o postquirúrgica, tratamiento que recibió la complicación posoperatoria. Durante la segmentación en burbujas por la pandemia COVID-19, a la clínica B asistieron 1184 pacientes, de los cuales 298 se realizaron exodoncias, quedaron excluidos 7 inmunosuprimidos. Del total de 291 se registraron n=15 (5%) complicaciones postoperatorias, las cuales correspondieron a alveolitis y hemorragias. El predominio de complicaciones postoperatorias se observó en mujeres, y con respecto a la ubicación de las piezas dentarias, la mayor frecuencia fue en piezas dentarias multirradiculares del maxilar inferior. Todas las complicaciones postoperatorias fueron tratadas con terapias locales. Dentro de las limitaciones del presente estudio, se puede señalar que, por el escenario de pandemia, el registro de pacientes se realizó con intervalos quincenales, lo que pudo contribuir a una subestimación de la prevalencia de complicaciones en los pacientes de la clínica.

Authors: Darya Abdollah , Shaikh Muhammad , Fernini Ilias , AlNaimiy Hamid
Published: December 2022

In this work, we analyze the phase scintillation index observed from the GPS, GLONASS, Galileo, and BeiDou satellite constellations, for a continuous period of three years. Our analysis reveals an elevated level of L1 phase scintillation observed from most GLONASS satellites, and none of the other GNSS constellations during the same period. This is of particular interest as the abnormality was observed during a solar minimum period, and from satellites labeled as healthy. Our observations were verified with data from four different receivers located in different regions. The goal of this study is to highlight these abnormal phase scintillations from GLONASS satellites as they may adversely affect the reliability and integrity of the GLONASS positioning service, especially during periods of heightened geomagnetic activity.
Re-Label By Data Pattern Is All You Need For Knowledge Driven Deep Learning
Authors: Guo Tong
Published: December 2022

In industry deep learning application, we should fix the badcase by human evaluation after we achieve more than 95% accuracy at dev dataset. The badcase reason is from the wrong rule/knowledge of human labeling and will cause low accuracy under human evaluation. In this paper, we propose the pattern-based method to fix the badcase for industry application inference. We propose the pipeline to solve the problem and improve the accuracy of human evaluation. The experiment results verify our idea, which means label-edit is the method to implement controllable deep learning application.
On modules over the mod 2 Steenrod algebra and hit problems
Authors: Võ Phúc Đặng
Published: December 2022

Let us consider the prime field of two elements, $\mathbb F_2\equiv \mathbb Z_2.$  It is well-known that the classical "hit problem" for a module over the mod 2 Steenrod algebra $\mathscr A$ is an interesting and important open problem of Algebraic topology, which asks a minimal set of generators for the polynomial algebra $\mathcal P_m:=\mathbb F_2[x_1, x_2, \ldots, x_m]$ on $m$ variables $x_1, \ldots, x_m,$ each of degree one, regarded as a connected unstable $\mathscr A$-module.  The algebra $\mathcal P_m$ is the cohomology with $\mathbb F_2$-coefficients of the product of $m$ copies of the Eilenberg-MacLan complex $K(\mathbb F_2, 1).$ Although the hit problem has been thoroughly studied for more than 3 decades, solving it remains a mystery for any $m\geq 5.$ In this article, we develop our previous work [Commun. Korean Math. Soc. 35 (2020), 371-399] on the hit problem for $\mathscr A$-module $\mathcal P_5$ in generic degree $n:=n_s = 5(2^{s}-1) + 18.2^{s}$ with $s$ an arbitrary non-negative integer. As an immediate consequence, a local version of Kameko's conjecture for the dimension of the cohit space $\mathbb F_2\otimes_{\mathscr A}\mathcal P_m$ associated with weight vectors is true for $m = 5$ and degree $n_s.$ Also, we show that this conjecture also holds for any $m\geq 1$ and degrees $\leq 12.$ Two applications of this study are to establish the dimension result for the cohit space $\mathbb F_2\otimes_{\mathscr A}\mathcal P_m$ for $m = 6$ in generic degree $5(2^{s+4}-1) + n_1.2^{s+4}$ with $s > 0$ and to describe the modular representations of the general linear group of rank $5$ over $\mathbb F_2.$ Our results then show that the algebraic transfer, defined by W. Singer [Math. Z. 202 (1989), 493-523], is an isomorphism in bidegrees $(5, 5+n_s)$ with $s\geq 0.$ Also, we prove that Singer's transfer is a trivial isomorphism in bidegree $(m, m+12)$ with $m$ an arbitrary positive integer.
AnyFace: A Data-Centric Approach For Input-Agnostic Face Detection
Authors: Kuzdeuov Askat , Koishigarina Darina , Varol Hüseyin Atakan
Published: December 2022

Face detection is a mandatory step in many computer vision applications, such as face recognition, emotion recognition, age detection, virtual makeup, and vital sign monitoring. Thanks to advancements in deep learning and the introduction of annotated large-scale datasets, numerous applications have been developed for human faces. Recently, other domains, such as animals and cartoon characters, have started gaining attention but still lag far behind human faces. The biggest challenge is the limited number of annotated face datasets in these domains. The manual labeling of large-scale datasets is tedious and requires substantial human labor. In this regard, we present an input-agnostic face detector to ease the annotation of various face datasets. We propose a simple but effective data-centric approach instead of building a specific neural network architecture. Specifically, we trained a face detection model, YOLO5Face, on human, animal, and cartoon face datasets. The experiments show that the model can achieve accurate results in all domains. In addition, the model achieved decent results for animals and cartoon characters different from the ones in the training set. This implies that the model can extract agnostic facial features. We have made the source code and pre-trained models publicly available at https://github.com/IS2AI/AnyFace to stimulate research in these fields.
Active Differential Reflection Coefficient of Differentially-Fed Antenna Array
Authors: Xu Guanghui
Published: December 2022

In this communication, a definition for the active differential reflection coefficient of the differentially-fed antenna array is proposed.  The each antenna is fed by two ports which input the equal-amplitude anti-phase signals. According to the active reflection coefficient of the conventional single-ended antenna array, the active differential reflection coefficient definition of the differential antenna array is given and analyzed. To verify the active differential reflection coefficient definition, the differential three-element microstrip patch antenna array is designed, fabricated and measured. In addition, it is derived and obtained that the active differential reflection coefficient of the differential port m is a half of the active reflection coefficient sum for the single-ended port m+ and m-. The active differential reflection coefficient definition will give a port match design guidance for the differential antenna array. 
A Static FEA Framework for Fast Analysis of HTS Armature Windings in AC Superconducting PM Machines
Authors: Hartmann Christian , Mellerud Runar , Nøland Jonas Kristiansen , Nilssen Robert
Published: December 2022

Macroscopic superconductivity models have improved significantly over the last decades. Formulations and methods have been developed to faster solve problems involving high-temperature superconductors (HTS). Despite these developments, finite element analysis (FEA) of AC superconducting machines (SCMs) with HTS coils still remains time-consuming. The combined burden from the HTS models and the moving mesh makes the models complex and slow. To deal with this challenge, a new framework for FEA of AC superconducting SCMs with surface-mounted permanent magnet (PM) rotors and HTS armature windings is proposed in this paper. In this approach, the rotating rotor geometry is emulated with a stationary array of small PM segments excited with time-varying boundary sources. The major benefit of this approach is that the models can be realized without moving meshes, which increases the computation speed by more than one order of magnitude. In our dedicated case study of a complete SCM design, the speedup factors are 17.4x and 38.5x for the H-A and T-A formulations, respectively. Over a large parametric space of 18 design permutations, the highest relative error in calculated HTS loss was 4.12 percent. As a result, this work enables the designer to perform much more comprehensive performance studies of SCMs.
Arrival- and service-curve estimation methods from measurements to analyze and design soft real-time streaming systems with network calculus
Authors: Funda Christoph
Published: December 2022

 This paper surveys different arrival and service curve estimation methods for basic linear functions from experimental data. We experiment with methods we found in literature and discuss the benefit and deficit of these methods. We propose two own developed simple methods inspired by literature, to estimate rate-latency service curves matching to our use case to analyze a soft real-time streaming system with Network Calculus. We furthermore apply three methods to a novel field for performance evaluation with network calculus: hardware-in-the-loop test benches. The performance evaluation of these test systems and the two estimation methods are our contribution to the field of network calculus applicated to soft real-time streaming systems. The performance metric playback buffer and the minimum needed pre-buffer time are dimensioned with the help of adapted and mathematically proven network calculus solutions for streaming devices from our last paper. Linear network calculus elements are generated in three different ways based on measurements of software processing latencies and network latencies. In the next step, playback buffer backlog and delay bounds are calculated based upon the three service curve estimation methods by applying network calculus to the measurements. These calculated bounds are compared to each other and discussed and furthermore verified by a discrete-event simulation model with trace-driven input and with distribution fits of the processing latencies. The simulation model uses a variation of the workload to prove the system, while being operated in soft real-time operating point, with the mean arrival-rate near the mean service-rate and above the minimum service-rate. We recommend using the delay metrics by NC with a safety-factor to design the pre-buffer time.

Offloading computation to Mobile Edge Vehicular Clouds (MeVC) is an effective mechanism to meet the expectations of the \textcolor{blue}{next-generation} IoT networks. MeVC applications \textcolor{blue}{rely} heavily on resilient, trusted, and reliable wireless communication as a pillar to support its operation. This paper presents a software-defined, flexible vehicular Ad-hoc NEtwork (Sd-VANET) architecture that enables the construction of resilient network infrastructure and the secure operation of MeVC. The Sd-VANET is managed by a novel situation-aware blockchain-based framework that dynamically reprograms the network topology and data flows at run-time to enable Moving-target Defense (MtD) applications against attacks and failures. The presented solution was mathematically modeled and analyzed. Simulations showed that the proposed system can effectively and efficiently improve the quality of communication services and their resilience against attacks and failures.

Published: December 2022

 This paper investigates covert communication in simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) assisted non-orthogonal multiple access (NOMA) systems, assuming for the sake of being more practical that the successive interference cancellation (SIC) is defective. To assess the covertness performance of the considered system, we first derive closed-form expressions for the detection error probability, the optimal detection threshold and the average minimum detection error probability of the warden, as well as the outage probability of the NOMA user pair. Then an optimization problem to maximize the effective covert rate (ECR) is proposed. According to the results of the simulation, it is possible to increase the maximum ECR of the considered system by varying the amount of components of the STAR-RIS.

Published: December 2022

The last decade witnessed the proliferation of automated content analysis in communication research. However, existing computational tools have been taken up unevenly, with powerful deep learning algorithms such as transformers rarely applied as compared to lexicon-based dictionaries. To enable social scientists to adopt modern computational methods for valid and reliable sentiment analysis of English text, we propose an open and free web service named transformer- and lexicon-based sentiment analysis (TLSA). TLSA integrates diverse tools and offers validation metrics, empowering users with limited computational knowledge and resources to reap the benefit of state-of-the-art computational methods. Two cases demonstrate the functionality and usability of TLSA. The performance of different tools varied to a large extent based on the dataset, supporting the importance of validating various sentiment tools in a specific context.

Understanding the Deltoid Phenomenon in the Perspective 3-Point Problem
Authors: Rieck Michael
Published: December 2022

Concerning the Perspective 3-Point (P3P) Problem, Grunert's system of three quadratic equations has a repeated solution if and only if the cubic polynomial introduced by Finsterwalder has a repeated root. This polynomial is shown to be equivalent to a particularly simple cubic polynomial with complex coefficients that provides surprising geometric insight into the P3P problem. In particular, (1) its discriminant can be written using the formula for the standard deltoid, and (2) this discriminant vanishes on a surface that approaches a deltoid shape when the camera is moved infinitely far from the control points in a direction perpendicular to the control points plane (the ``limit case"). These two facts have been previously reported, but obscure reasoning was required to establish them. In contrast, the present article uses the newly discovered cubic polynomial to easily produce the first fact, which then provides a basis for better understanding the second fact. Geometric insight into the P3P solution points in the limit case is also provided.

Published: December 2022

Little is currently known about how varied source locations affect a listener’s emotional reaction to music. Here, using spectral features extracted from electrophysiology (EEG) data, we tested through machine learning whether four music source positions (front, back, left, and right) could be accurately distinguished according to the type of valence in a subject-wise manner. The findings demonstrate that distinct EEG correlates can reliably classify the four source locations and that the effect is stronger when music with a negative emotional va- lence is played outside of the listener’s visual field. This proof-of-concept study may pave the way for advanced spatial audio analysis approaches in music infor- mation retrieval by considering the listener’s emotional impact depending on the source direction of incidence.

Tulang ayam merupakan salah satu jenis limbah padat yang mengandung sumber protein berupa kolagen. Kolagen merupakan salah satu dari jaringan ikat utama protein hewani dan banyak digunakan sebagai bahan biomedis, dan memiliki efektivitas sebagai anti-aging. Anti-aging dalam sediaan krim mampu mencegah penuaan pada kulit. Penelitian ini bertujuan untuk mengetahui apakah kolagen tulang ayam broiler dapat diformulasikan dalam sediaan krim yang pada konsentrasi tertentu dapat memberikan efek anti-aging dan tidak mengiritasi kulit. Penelitian ini memakai metode eksperimental, menggunakan bahan uji tulang ayam broiler. Tahapan penelitian ini meliputi isolasi kolagen dari tulang ayam broiler, karakteristik kolagen dengan spektrofotometri inframerah, pembuatan krim kolagen tulang ayam broiler dengan konsentrasi 1%, 1,5%, 2,5% dan 3,5% dan evaluasi sediaan krim serta uji efektivitas anti-aging menggunakan alat skin analyzer (aramo) dimana hasilnya diuji secara statistik memakai uji ANOVA dengan SPSS 26 free trial. Hasil penelitian menunjukkan bahwa kolagen tulang ayam broiler dapat diformulasikan dalam sediaan krim anti-aging dengan tipe emulsi minyak dalam air (M/A) hasil evaluasi sediaan merupakan sediaan yang homogen, stabil dan tidak mengiritasi kulit dengan rentang pH 6,1-6,4. Hasil uji statistik menunjukkan probabilitas lebih kecil dari 0.05. Formulasi krim kolagen tulang ayam broiler dengan konsentrasi 3,5% menunjukkan efektivitas anti-aging yang terbaik dengan meningkatnya kelembaban 25,2%, mengurangi pori 22,2%, mengurangi noda 22,9% dan mengurangi keriput 22,3%.

Introducción: La depresión es uno de los trastornos mentales que más afecta a la humanidad, es una enfermedad frecuente, por lo tanto, el estudio estuvo orientado a determinar el grado de depresión en estudiantes extranjeros a través del Inventario de Depresión de Beck-II (BDI-II). Metodología: El trabajo de investigación fue cuantitativo, los diseños de investigación fueron descriptivo, de cohorte transversal, prospectivo y observacional; la población de estudio corresponde a 260 universitarios; el muestreo fue no probabilístico por criterios de inclusión, el instrumento utilizado fue el Inventario de Depresión de Beck-II (BDI-II), este cuestionario consta de 21 preguntas, donde 0-13, mínima depresión, 14-19, depresión leve; 20-28, depresión moderada, y 29-63, depresión grave. Resultados: se evidenció que un 84 % de estudiantes proceden de Brasil, el estado civil de mayor frecuencia 66,9 % fueron los solteros. Además, el 97,4 % son estudiantes de medicina, respecto a los grados de depresión se evidencia, 39,6 % de los estudiantes evaluados presentan un mínimo cuadro de depresión, 12,7 %, presenta grado leve, el 20 % evidencio moderado, y el 27,7 % reporto un cuadro severo. Discusión: En relación con otros estudios los datos discrepan y con algunos son casi similares; principalmente con estudios de Brasil y otros países vecinos como Paraguay, por lo tanto, la depresión en universitarios es muy frecuente por las distintas actividades y responsabilidades que van asumiendo, por eso se debe de implementar estrategias de promoción y prevención de salud mental, para poder coadyuvar en la calidad de vida.
