Published: March 2023

The purpose of this study is to describe, explain and validate the visual representation of hell from Balinese Hindu beliefs in the video game “Escape From Naraka”. The video game “Escape From Naraka” is a game with the platform adventure genre and is played solo that tells the journey of a man who enters the hell portal of the Balinese Hindu beliefs to save a woman who is sucked in by the portal. This video game is developed by the origin of Yogyakarta - Indonesia, namely XeloGames and published by Headup Games company from Germany. The method used in this research is descriptive qualitative research with library data method. The research was conducted by examining the visual representation of hell from Balinese Hindu beliefs in the video game “Escape From Naraka”, then linking it with writings related to the theme. In this study, the description uses facts from the data obtained as they are. The results of this study indicate that there are representations of hell that are not in accordance with Balinese Hindu teachings and display some visual representation objects from teachings or cultures outside Balinese Hinduism so that there are errors in visual representation. There are many things that may be wrong in the visual representation of Tamrisra/Tamisra Naraka in the video game "Escape From Naraka" such as Thai Statue and other objects that are not in accordance with Balinese culture. This research has an impact on the development of visualization designs in video games that can encourage players to have a misperception of culture. So that the results of this study can be a criticism and help game developers to be more careful in visualizing video games, especially those based on belief and culture.

Les évêchés byzantins de la Calabre septentrionale au VIIIe siècle
Authors: Prigent Vivien
Published: March 2023

Notre connaissance de l’organisation épiscopale de l’empire byzantin repose essentiellement sur les Notitiae episcopatuum. Pour le VIIIe siècle, la fiabilité de la notice 3, qui fournit les renseignements les plus précis, est malheureusement largement sujette à caution. Elle mentionne, en effet, trois sièges disparus depuis le siècle précédent ou dont la fondation n’est attestée qu’au tournant des IXe-Xe siècles. L’examen des sources sigillographiques permet de réhabiliter cette source en documentant l’existence, dans la première moitié du VIIIe siècle, des trois sièges concernés, Rossano, Santa Severina-Nicopolis et Amantea. L’image de la situation de l’Église hellénophone au nord de la Calabre à cette époque s’en trouve considérablement modifiée. Les sites retenus illustrent la politique de défense des Isauriens qui fondent des évêchés dans les kastra stratégiques de la frontière lombarde, selon une méthode déjà mise en lumière en Thrace face aux Bulgares.

Authors: Johns Jeremy
Published: March 2023

il Kitāb Ġarā'ib al-funūn wa-mulaḥ al-'uyūn (Libro delle curiosità delle scienze e delle meraviglie per gli occhi) è l’unico manoscritto finora conosciuto di un trattato cosmografico compilato da un autore anonimo, quasi certamente egiziano, nella prima metà dell’XI secolo d. C. Il capitolo XII del II libro è dedicato alla Sicilia e comprende una descrizione di Palermo, derivata in parte da Ibn H ˙ awqal (che visitò l’isola nel 972-73), che contiene anche nuovi materiali sulla storia e topografia di Palermo nella prima metà dell’XI secolo. Comprende anche una straordinaria mappa della Sicilia islamica che riporta un ammasso di nuovi dati topografici e toponoma stici per l’isola – e soprattutto per Palermo – attorno all’anno 1000. Questo contributo presenta la prima edizione critica e traduzione dei testi, e da un primo resoconto di questa importante fonte nuova per la Sicilia islamica.

Authors: García-Torres Jorge Alfredo , González-Méndez Agustín , Hernández-Zavala Antonio
Published: March 2023

Motion difficulties, specifically the walk and displacement, are very common afflictions, mainly caused by some type of injury. The recurrent kind of rehabilitation treatments involve exercises of active and passive mobility. The success in the treatment and the early return to sports activity depends largely on the rehabilitation process. This should begin immediately after the production of the wound or the surgical process to repair the damage. The objective of this work is to develop a low-cost, easy manufacturing and assembly device, capable of providing exercises of active mobility. We designed an affordable and adaptable six-bar Watt linkage, coupled to a conventional leg extension machine. Structural and dynamic studies determine its safeness and its efficiency. The results of the kinematic and dynamic studies showed that the available range of motion for the different configurations goes from 24° to 109°. Its structural integrity was analyzed, pointing out that the weakest link had a Factor of Safety of 1.3, while the highest presents a value of 14.7, so that, the material overpasses the load needs. Based on the obtained results, a six-bar linkage is a viable option for the development of low-cost, therapeutic active devices.
Optimal active yaw control for a wind turbine
Authors: Villafuerte-Altúzar Eugenio , Gurubel-Tun Kelly Joel , Haro-Falcón Nicolás
Published: March 2023

In this work a control strategy based on the mathematical model of an active yaw system for a 20 KW horizontal axis wind turbine is proposed. It allows to increase its efficiency in the presence of changes in the intensity and direction of the wind. The inverse optimal control strategy is implemented based on the mathematical model using the equations of state that represent the dynamics of the yaw system, whose model was obtained with the FAST program, specialized software for modeling wind turbines, which allows obtaining the mathematical model of the orientation system in a more precise way. The results are presented via simulation, where the control strategy is validated in the presence of disturbances. The contribution of this work lies in the application of the optimal control strategy and the tuning parameter search strategy of the control law.

Authors: Zavala-Contreras Francisco Javier , Alazki Hussain , Cortés-Vega David , Golikov Victor
Published: March 2023

This paper proposes the study of a vision-based control scheme for an Unmanned Aerial Vehicle (UAV) for tracking objects floating on the sea surface. The applied vision scheme is based on the generalized likelihood ratio test (GLRT) algorithm. Once the target is detected, its coordinates are computed and used by the UAV control to track the target. The quadrotor mathematical model is developed using the Newton-Euler approach and a PID controller is implemented to track the vector containing the coordinates obtained through the vision scheme. To verify the effectiveness of the proposal, simulation tests are developed in MATLAB/Simulink based on a real video of an objective floating in the sea surface. The obtained results show an appropriate detection and tracking of the objective.

El avance de la gran minería sobre el territorio
Authors:   , Villamil Velásquez Javier Fernando
Published: March 2023

El trabajo de grado se enmarca en el proceso de avance de las grandes empresas extractivas en el área latinoamericana, particularmente a partir de la década de los años 90s con la emergencia del neoliberalismo. El documento concentra su análisis en los fenómenos sociales que se han desencadenado a partir de la irrupción de empresas mineras en Colombia y Argentina, escogiéndose a su vez dos regiones de estos países para ejemplificar el fenómeno. Estos casos regionales y los escenarios nacionales, serán analizados a la luz de una temporalidad específica: periodo 1995 -2013. Cabe decir que el actor protagonista de esta investigación es la empresa transnacional. El elemento central es la dinámica territorial desencadenada a partir del proceso extractivo, producto del afianzamiento geográfico de los grandes grupos mineros. A partir de allí, se intenta mostrar las repercusiones en campo, revelar un análisis de las realidades nacionales y a su vez, debelar discusiones teóricas y debates neurálgicos que de allí se desprenden. Se pretende contribuir hacia una reflexión amplia y crítica con respecto al la estructura económica, al extractivismo, al territorio, a la geopolítica y al Estado, en función de la consolidación de un modelo minero de carácter transnacional.

Published: March 2023

In this study, a numerical simulation of edge-defined film-fed growth (EFG) was performed to determine the appropriate capillary conditions for Ga2O3 melt. Meniscus and capillary rise were significantly influenced by the design of the die in the EFG system. The ratio of the seed crystal and die width was >0.73 for a die width of 4.4 mm. Narrower slit width resulted in higher capillary rise with longer process time compared with wider slit width. Under conditions consistent with the simulation results, highly crystalline (100) β-Ga2O3 single crystals were successfully achieved.
In situ electrical monitoring of SiO2/Si structures in low-temperature plasma using impedance spectroscopy
Authors: Morozumi Junki , Goya Takahiro , Kuyama Tomohiro , Eriguchi Koji , Urabe Keiichiro
Published: March 2023

To investigate the electrical properties and degradation features of dielectric materials during plasma exposure, we developed an in situ impedance spectroscopy (IS) system. We applied the proposed system to monitor SiO2/Si structures exposed to Ar plasma. By analyzing the measured data based on an equivalent circuit model considering the plasma and SiO2/Si structures, we obtained the resistance (R) and capacitance (C) values for the SiO2 film and SiO2/Si interface. In a cyclic experiment of in situ IS and high-energy ion irradiation, we characterized dielectric degradation by ion irradiation based on the variations in the R and C values of the SiO2 film. A continuous in situ IS measurement revealed temporal variations in the electrical properties of the film and interface independently. The thickness-dependent degradation observed for the RC variation was analyzed and compared with the results of previous ex situ measurement studies. This study demonstrates that the in situ IS measurement technique is promising for monitoring plasma-assisted dry processes.

Authors:   Korean Constitutional Law Asscciation, Choi Kyungho
Published: March 2023

The Multicultural Family Support Act was enacted in 2008 and aims to contribute to the improvement of the quality of life and social integration of multicultural family members by allowing them to lead stable family lives and fulfill their roles and responsibilities as social members. The general targets of support under the enactment of the Multicultural Family Support Act are support for families consisting of national spouses, marriage immigrants, and their children. This paper evaluates whether the core legislative purpose of the Multicultural Family Support Act, which contributes to the ‘social integration of members of multicultural families’, is being effectively achieved. Legislative evaluation was conducted focusing on Article 1 (purpose clause), which specifies the legislative purpose of the Multicultural Family Support Act, Article 5 (promoting understanding of multicultural families), and Article 6 (support for life information and education). At the time of legislation, multicultural families in Korea were more related to Southeast Asian-centered marriage immigrants than multicultural families from Western developed countries. Therefore, the stability of their lives and desirable settlement in our society were a problem, and the Multicultural Family Support Act aimed at this purpose is considered to contribute to the improvement of the quality of life and social integration of multicultural families along with the designed legislative purpose. This study was conducted focusing on the post-legislative evaluation of the Multicultural Family Support Act, and was conducted by applying a typical post-legislative evaluation methods, including tests of legislative effectiveness and performance and problems of the current law in the application of the law.
Eine verfassungsrechtliche Untersuchung über die Bedeutung und den Schutzbereich des Selbstbestimmungsrechts
Authors:   Korean Constitutional Law Asscciation, Lee Se Joo
Published: March 2023

Dieser Arbeit behandelt das verfassungsrechtliche Thema über die Bedeu- tung und den Schutzbereich des Selbstbestimmungsrechts als ein einzelnes Grundrecht in der koreanischen Verfassung. Im Kapitel II schreibt die korea- nische Verfassung grundsätzlich die meisten Grundrechten und -pflichten der Staatsbürger(Art. 10∼Art. 39) vor. Im Art. 37 Abs. 1 wird dann die in der Verfassung nicht aufgezählten Grundrechte vorgeschrieben, nämlich Freiheit- en und Rechte der Staatsbürger werden nicht aus dem Grund außer acht ge- lassen, dass sie in der Verfassung nicht aufgezählt seien. In der koreani- schen Verfassung wird ein Selbstbestimmungsrecht als ein einzelnes Grund- recht nicht direkt vorgeschrieben, sondern wird es als ein in der Verfassung nicht aufgezählten Grundrecht normalerweise bisher von der zahlreichen Ent- scheidungen des koreanischen Verfassungsgerichts anerkannt. Von daher wird das Thema über die Bedeutung und den Schutzbereich des Selbstbe- stimmungsrechts als ein einzelnes Grundrecht von der meisten verfassungs- rechtlichen Diskussionen nach wie vor behahandelt. Außerdem ist es noch umstritten, ob das Selbstbestimmungsrecht in der koreanischen Verfassungs- theorie ein einzelnes Grundrecht ist. Einerseits erkennen die Entscheidungen des koreanischen Verfassungsgerichts das Selbstbestimmungsrecht als ein ein- zelnes Grundrecht, andererseits erklären sie das Selbstbestimmungsrecht als ein Kernbegriff und -inhlat des Schutzbereiches der einzelnen Grundrechten. Eine Verstandnisschwierigkeit über die verfassungsrechtliche Bedeutung und den Schutzbereich des Selbstbestimmungsrechts verursacht werdet, weil es noch unklar insbesondere in der zahlreichen Entscheidungen des koreani- schen Verfassungsgericthts. Eine verfassungsrechtliche Untersuchung über die Bedeutung und den Schutzbereich des Selbstbestimmungsrechts ist vor allem in der Ebene der Grundrechtstheorie bei uns in Korea und der Recht- sprechungen des koreanischen Verfassungsgerichtes noch bedeutungsvoll.
A Constitutional Review of Election Lawsuits: With a Focus on the Adjustment of the Institution in Charge

An election is a significant constitutional opportunity and process to constitute state institutions and confer democratic legitimacy through the intent of the people, who have sovereign power. If a problem arises in such an election process, it can pervert the intent of the people and impact the establishment of the intent of the nation; hence the need for a process to resolve this kind of situation. The evaluation of such an election has the characteristics of a constitutional trial, as it broadly affects both the political and constitutional realms, and there are many cases where, if there is a separate institution designated for constitutional trials, that institution oversees this. Nonetheless, as the formation of a specific system is a matter of policy, the way it is handled differs according to the unique situation of each country. Under the current system, election lawsuits are overseen by courts, but the adjustment plan of the institution in charge that takes into consideration the heavy workload of the Supreme Court may become an issue. Unlike local elections, presidential and legislative elections relate to the composition of constitutional institutions and the granting of legitimacy by the sovereign intent of the people. Furthermore, their significance and effect on the national level make the Supreme Court’s jurisdiction over them and the High Court’s jurisdiction over local elections reasonable. Considering the policy-forming role expected of the Supreme Court to ensure that jurisdiction is exercised consistently and that the constitutional state is specifically realized, the significance of the resolution of the Constitution to set up the National Election Commission as an independent institution, the need to resolve election-related disputes expeditiously, the maintenance of political neutrality, etc., it is judged that the basis for this is considerable.
Study on the Protection of the Right to Self-Determination of Personal Information with the Development of Facial Recognition Technology

Biometrics technology has rapidly developed over the past few years and has been implemented and used in real life for identity verification. The introduction of biometric technology without proper protection could cause invasion of privacy, especially personal information, which requires the constitutional study, however. Specific regulations should be prepared for facial recognition information, in particular. The infringement caused by leakage is enormous as the biometric information, including facial recognition information, has the characteristic that it does not change unlike existing personal information. Moreover, it could be said that it is urgent to establish regulations on the current situation where ‘intelligent CCTV’ with facial recognition functions is being introduced. In Illinois, U.S., the Biometric Information Privacy Act (BIPA) establishes regulations on biometric information, and Facebook was liable for $650 million in damages for violating it. Since then, U.S. civic groups have demanded the suspension of the use of facial recognition technology, and bills to strengthen the facial recognition system and prohibit facial recognition technology have also been proposed. Although Korea protects biometric information as sensitive information through the Personal Information Protection Act and the Enforcement Decree of the same Act, improvements of the Personal Information Protection Act are required by focusing on the risk of personal information infringement of facial recognition technology. Regulations for exceptional handling of sensitive information should be more specific and regulations for liability for damages due to violations of the law should be improved, and regulations for ‘intelligent CCTV’ should also be prepared.
A Study on the Availability of a Claim for Competence Dispute in Where a Basic Local Government Seeks the Cancellation of an Illegal Disposition by a Metropolitan Local Government
Authors:   Korean Constitutional Law Asscciation, Park Jin Yeong
Published: March 2023

A request for adjudication on competence dispute, in which a local government disputes the illegality of the sovereign disposition of a metropolitan local government and seeks its cancellation, should be dismissed as unlawful since it cannot be regarded as a dispute over the ‘existence or scope of authority’ that can be the subject of a competence dispute adjudication and the respondent's disposition has no possibility of violating the constitutional or statutory authority of the complainant. In the interpretation of the current Constitution and laws, the competence dispute adjudication and the appeal suit may be placed in a situation of jurisdictional competition. Considering that disputes over the ‘existence’ or ‘scope’ of authority are subject to dispute adjudication, when the state or a local government exercises authority that contradicts the authority of another local government, authority dispute trial should be conducted. On the other hand, in cases where it is clear that whether the exercise of the sovereign authority of the state or a certain local government violates legal requirements is the only issue, it is necessary to see that only appeal proceedings are permitted.
On modules over the mod 2 Steenrod algebra and hit problems
Authors: Võ Phúc Đặng
Published: March 2023

Let us consider the prime field of two elements, $\mathbb F_2.$  The classical "hit problem" in Algebraic Topology, which is widely considered to be an important and fascinating open problem that has yet to be resolved, asks for 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 which has 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 $K(\mathbb F_2, 1)$. Despite extensive study over the past three decades, the hit problem remains unresolved for $m\geq 5$. 

In this article, we develop our previous work [Commun. Korean Math. Soc. \textbf{35} (2020), 371-399] on the hit problem for $\mathscr A$-module $\mathcal P_5$ in the generic degree $n_s = 5(2^{s}-1) + 18.2^{s}$ with $s$ an arbitrary non-negative integer. As a consequence, a localized variation  of the Kameko conjecture, which concerns the dimension of the cohit space $\mathbb F_2\otimes_{\mathscr A}\mathcal P_m$ in relation to parameter vectors, has been claimed to be veracious in the instance where $m = 5$ and the degree is $n_s.$ Also, we show that this conjecture also holds for any $m\geq 1$ and degrees $\leq 12.$ This study has two important applications:  (1) it establishes the dimension result for the cohit space $\mathbb F_2\otimes_{\mathscr A}\mathcal P_m$ for $m = 6$ in the generic degree $5(2^{s+4}-1) + n_1.2^{s+4}$ with $s > 0;$ and (2) it describes the representations of the general linear group of rank $5$ over $\mathbb F_2.$ As a result, we prove that the algebraic transfer, defined by W. Singer [Math. Z. \textbf{202} (1989), 493-523], is an isomorphism in bidegrees $(5, 5+n_s)$ with $s\geq 0.$ Besides, we obtain new results on the behavior of this algebra transfer for all homological degrees $m$. Specifically, we demonstrate that Singer's transfer is a trivial isomorphism in bidegree $(m, m+12)$ for any $m > 0$.
Extraction of Transformer Parameters from FEMM Simulations and Automated Creation of a Transformer SPICE Model Using a Scripting Language
Authors: ZAIKIN DENYS
Published: March 2023

This study presents a method for extracting transformer parameters using simulations in the Finite Element Method Magnetics (FEMM) electromagnetic solver. The extracted parameters represent a full model of a linear transformer and can be used in Simulation Program with Integrated Circuit Emphasis (SPICE) simulations. A model of the transformer is presented in three variants, for which different approaches were used in the transformer simulation in the SPICE program, all yielding the same simulation results. A method for extracting transformer parameters from FEMM is proposed, along with an automated tool based on a scripting language built into the FEMM software.
