Authors: Li Yiyang , Yuan Fang
Published: July 2024

The distinctive attire of the Zhuang ethnicity is the most direct expression of its folk culture. The positive development and utilization of ethnic costumes can significantly benefit Zhuang folk tourism. Incorporating elements of ethnic costume culture, such as patterns, colors, fabrics, and decorations, into modern design can enrich the ethnic cultural connotations of contemporary design practices. This research project, taking the Zhuang Fu Rui cultural dolls as a case study, discusses the integration and continuation of minority culture with modern design. By merging Zhuang costume culture with "Fu Rui" culture, the study explores the incorporation of traditional cultural elements into modern design, aiming to preserve and promote Zhuang culture. Additionally, the paper uses case analysis to deeply examine the role of cultural and creative products in the inheritance of Zhuang culture, suggesting that products combining Zhuang culture with Fu Rui culture can effectively facilitate the transmission and spread of traditional culture.
Design of a news recommendation model based on collaborative filtering and LSTM
Authors: Huang Yiyang
Published: July 2024

This paper aims to design a news recommendation model based on user preferences to address the issues in recommendation systems under large datasets. Initially, four datasetsclick_history, news, news_embedding, and user_predictwere integrated into a single table, followed by data cleaning and feature engineering. Due to the large volume of data, this paper proposes necessary data filtering for the training and testing sets, utilizing temporal data to construct user feature vectors and news feature vectors. One challenge is how to effectively integrate user preferences and news features into the model to avoid overfitting or underfitting. In the model design and building phase, different methods were attempted to merge the information of users and news. Ultimately, the user preference features were processed using a fully connected layer, and the news embedding vectors were handled using an LSTM model. These two data parts were then combined into another fully connected layer, using ReLU as the activation function and CELoss as the loss function. Subsequently, the model's hyperparameters were adjusted and evaluated, achieving favorable model performance. The prediction accuracy for recommending news to users in user_predict was calculated as an evaluation criterion. Finally, this paper proposes directions for generalization and optimization in three aspects: data processing, model design, and experimental design. This includes data processing methods, potential improvements or mechanisms that could be incorporated into the model, and hyperparameter tuning. The paper primarily proposes data filtering to solve the problem of excessive data scale, which may aid in addressing recommendation system issues under large-scale datasets.

Published: July 2024

A small Brazilian speech corpus was created for educational purposes to study a state-of-the-art speaker recognition system. The system uses the Gaussian Mixture Model (GMM) as a statistical model for speakers and employs the Mel-frequency cepstral coefficients (MFCC) as acoustic features. The results using clean and noisy speech are compatible with the expected results, showing that the bigger the mismatch between training and test conditions, the worse the results. The results also improve with the increase in the utterance length. Finally, the obtained results can be used as baselines to compare with other speaker statistical models created with different acoustic features in different acoustic conditions.

Published: July 2024

The goal of this study was to create a prototype of an automatically guided rice transplanter using a Pixhauk flight controller, 3DR telemetry, Raspberry Pi, Tof sensor, gyro sensor, and other GPS navigation sensors to determine the field performance of that machine. GPS was used to obtain data such as location, direction, and speed, whereas machine vision can provide a navigation line. The next position of the transplanter can be determined using feature points extracted from the navigation line. The controller area network bus complies with the actuator control command and data communication protocols. Electrical actuators control steering and transmission based on a vehicle's location in a field. The percentage of missing, buried, and floating hills was observed to be 1.6%, 1.4%, and 3.0%, respectively, as the maximum values were found in clay soil at T1. Over time, percentages of losses decreased, and the lowest percentage of losses was given. The lowest percentage of missing, buried, and floating hills was found at 0.8%, 0.2%, and 0.8%, respectively, in clay loam soil at T5. Planting efficiency improved, and losses decreased as treatment levels upgraded. Clay loam soil in T5 had the highest planting efficiency percentage (88%), whereas clay soil in T1 had the lowest (61%) proportion. The findings indicated that T4 and T5 enhanced rice output by decreasing the losses incurred during seedling transplantation. The study suggested that the developed rice transplanter might be suitable for planting rice seedlings to establish meaningful mechanization through precision agriculture technology.

Published: July 2024

Tooth decay is a dental condition characterized by the deterioration of tooth tissue, originating from the outer surface and progressing to the pulp. Severe tooth decay, evolving into cavities, necessitates timely intervention to avert more serious dental health issues. Common treatment procedures include filling and extraction of affected teeth. Presently, dentists conduct examinations for tooth decay by manually tallying affected, missing, and filled teeth using an odontogram—a human tooth code diagram. This data is then recorded in patients' dental medical records. Recognizing the need for automation in assessing patients' experiences of tooth decay, this research endeavors to develop a model capable of detecting decayed, missing, and filled teeth using variations of the YOLOv5 and YOLOv8 model architectures. The results of the training evaluation demonstrate the efficacy of YOLOv5l with a learning rate of 10-2, exhibiting a high precision value of 0.97, recall of 0.858, and a mean average precision (mAP) of 0.904 within 1 hour and 18 minutes. According to the curves obtained in training process, YOLOv5l shows great performance on the dental caries dataset, but precautions like early stopping are needed for a reliable and generalizable model. In contrast, YOLOv8, offers better training stability and larger variants perform better on the dental caries dataset, improving detection capabilities with continued training epochs.
A Robust Backstepping Controller Based on Nonlinear Observer for Shunt Active Filters to Improve Power Quality in Four-Wire Distribution Systems
Authors: Sarafrazi Parisa , Taher Seyed , Akhavan Ali
Published: July 2024

This article introduces a novel approach to enhance the performance of LCL based active power filters (APFs) in four-wire distribution systems by employing a nonlinear current control strategy. The strategy combines backstepping control (BSC) and a nonlinear disturbance observer (NDOB) to effectively manage harmonic and interharmonic grid currents. By situating the shunt active power filter (SAPF) at the point of common coupling (PCC) via the LCL filter, the technique ensures that grid connected currents remain balanced and purely sinusoidal. The integration of NDOB with BSC aims to fortify the resilience of BSC against disturbances. Consequently, any disturbances occurring within the system are precisely estimated by the NDOB and subsequently mitigated through the BSC mechanism. Notably, this approach showcases robust adaptability across diverse scenarios, encompassing external disturbances, variations in filter parameters, nonlinear loads laden with harmonics and interharmonics, load imbalances, and non-ideal grid voltages. Its performance remains robust and stable even when disturbances are present. Comparative analysis with linear-based methodologies underscores the advantages of this approach, revealing quicker and smoother transient responses. The efficacy of the proposed technique is demonstrated through comprehensive simulation studies, substantiating its potential for significantly advancing power quality in complex distribution systems.

The solution of the elastic-plastic contact is of major importance in contact mechanics because contact damage and wear are responsible for the failure of many machine elements subjected to contact load. In many situations including gears and bearings, the load is transmitted through a small contact region, i.e. a concentrated contact, and the resulting high gradients of stress often exceed the plastic yield limit of the softer material. Plastic flow is initiated at a certain depth, resulting in modification of contact geometry and of the stress state that can lead to crack inception and propagation. Understanding the contact behaviour in the presence of plastic strains is fundamental for predicting the contact resistance. Considering the mathematical model complexity for the contact between bodies of arbitrary boundary, as well as the dissipative nature of plasticity, an analytical solution for the elastic plastic contact problem is hard to accomplish. Alongside finite element analysis, semi-analytical methods are the only existing simulation tools for the elastic-plastic contact problems. This paper extends a previously reported elastic-plastic contact solver developed by the same author, by considering friction. In the previous solver iteration, residual displacements were calculated only in the normal contact direction, thus assuming that the shear displacements are small enough to be neglected, in other words, the contact was assumed frictionless. By considering friction, a slip-stick contact process is introduced, adding a new iterative loop in which the contact pressure and shear stresses are iterated until convergence is reached. The new computer simulation tool is expected to give more realistic predictions for the elastic-plastic contact between materials with dissimilar elastic properties, in which case the shear tractions disturb the stress and displacements fields calculated for the frictionless contact case. The results are expected to contribute to a better understanding of the contact processes in the presence of both plastic strains and friction.

The article presents the method of preparing the tube sheet of a heat exchanger made of B265 Grade 1 titanium-clad steel with B338 grade 2 titanium tubes allowing for the qualification of the TIG (Tungsten Inert Gas) orbital welding technology. A test plate was made of A516M Grade 485 unalloyed steel clad with B265 Grade 1 titanium using the explosive method. The 300 x 300 mm plate consisted of a layer of 60 mm thick non alloy steel and 5 mm titanium clad. It had 20 holes drilled in a triangular arrangement, into tubes with a diameter of 34.93 mm made of B338 Grade 2 titanium with a thickness of 0.7 mm were welded. In order to obtain mechanical restraint inside the holes in the test plates, the titanium tubes were rolled out. For rolling, a five-roller was used, equipped with a retaining collar which allows the tube to move freely during rolling. The tests carried out showed that the proposed technology for preparing tube – sieve bottom elements allow for the preparation of a test plate for the qualification of welding technology. The test plate made in accordance with the technological assumptions met all the requirements necessary to qualify the technology for welding tubes with tube plates. Both in the case of non-destructive testing and macrographic testing, there were no problems with compliance with the PN-EN ISO 15614-8:2005 standard.

This paper presents multi-objective optimization of machining parameters, i.e., electrode materials, peak current, pulse on time and pulse off time in EDM of magnesium alloy-ZE41. The objectives such as metal removal rate, tool wear rate, surface roughness, recast layer thickness and radial overcut were optimized using MARCOS algorithm and three objective weighing methods, i.e., SD, CRITIC and MEREC. Taguchi’s L27(34) orthogonal array was used for conduction of experiments. ANOVA results showed that electrode material, interaction of electrode material and peak current and pulse on time were the most significant parameters for all weighing methods. Comparative study indicated that the percentage improvement in performance at optimal parameter setting were 37.21%, 32.30% and 10.68% for SD, CRITIC and MEREC respectively. Confirmation results indicated that all objectives except tool wear rate were improved positively for SD and CRITIC, but all objectives except metal removal rate deteriorated for MEREC.
EVALUATION OF SUPERPLASTIC PROPERTIES OF AA7075 ALUMINUM ALLOY SHEET FABRICATED BY THERMOMECHANICAL PROCESSING
Authors: Nguyena Manh Tien ,   Vietnam, Nguyena Truong An ,   Vietnam
Published: July 2024

The superplastic forming (SPF) process is the large plastic deformation ability of metals and alloys. However, SPF ability can only be achieved under certain conditions including ultrafine grain (UFG) microstructure, high temperature, and very small strain rate. In this work, the high-strength aluminum alloy AA7075 was selected for the experimental process due to its outstanding industrial application. First, thermomechanical processing (TMP) is performed to create a fine stable grain size for the studied alloy. The UFG microstructure was obtained after TMP with an average grain size of about 10 μm. Subsequently, the tensile test method and the bulging free-forming (BFF) method were used to evaluate the superplastic properties of the AA7075 aluminum alloy sheet fabricated by TMP. These two methods are performed at temperatures of 500ºC and 530ºC with strain rates from 10-4 (s-1) to 10-3 (s-1). The relative elongation and the strain rate sensitivity are the evaluation criteria. At the temperature of 530ºC and strain rate of 10-3 (s-1), the maximum relative elongation and flow stress were achieved at 280% and 7.6 MPa, respectively. The value of the coefficient m ranges from 0.3 to 0.6. The obtained results confirm the SPF properties of the aluminum alloy sheet AA7075.

In nature, matter is found in solid, liquid or gaseous form. At very high temperatures, molecules can absorb an enormous amount of energy, causing them to move in a disordered way. With the absorbed energy, they can dissociate into atoms, and because of their disordered motion, these molecules or atoms can split into ions and electrons. Excessive heating of matter is therefore always accompanied by ionisation, leaving the medium electrically neutral. This ionised state is known as plasma. It is sometimes called the fourth state of matter. Plasmas are therefore mixtures of neutral and/or excited ions, electrons, atoms, radicals or demodules with an internal energy above the neutral state. Sources of plasma can be as follows: naturally occurring in the ionosphere; produced by nuclear reactions; generated by a hyperfrequency source; formed by direct heating followed by confinement in a region of space by a magnetic field; and produced by electrical discharges. Plasma is characterised by the state of its components: density, which is defined by the number of particles per unit volume; kinetic temperature; and degree of ionisation. Plasma can be thermal or out of thermal equilibrium, or 'cold plasma'. Cold plasma is formed, for example, when a gas passes through strong electric fields - electrons are dissociated from the molecules and the gas becomes electrically conductive and glows blue. The paper describes the equipment used to create cold plasma, which was used to treat different surfaces. After treatment, they were bonded with different adhesives and tested for tensile strenght. An improvement in the mechanical properties mentioned above was observed when the surfaces to be bonded were treated with cold plasma compared to surfaces bonded normally. When the impact of cold plasma treatment on elongation, or ε, is examined, it is found that for Fiber Wood samples, cold plasma treatment considerably boosts elongation, increasing it from 0.35% for untreated samples to 0.81% for samples treated with cold plasma. For samples that have been treated with cold plasma, the average value increases significantly from 0.03% to 0.63% when ArbofillFichte material is used. In addition, the application of cold plasma treatment to the surfaces results in an increase in the modulus of elasticity. For example, the modulus of elasticity doubles for Arbofill Fichte samples, going from 113.56MPa for untreated samples to 227.43MPa for cold plasma treated samples; for Fiber Wood, it increases from an average value of 789.52MPa for untreated samples to an average value of 931.62MPa for treated samples.

A poluição sonora, diferentemente dos outros tipos de poluição, não deixa traços visíveis de sua influência no ambiente. Segundo a Organização Mundial da Saúde, o indivíduo exposto ao ritmo de vida intenso, horas de sono reduzidas, trânsito, indústria e tantas fontes de ruído somadas aos diversos outros fatores (período, condições gerais de saúde, idade e acústica do ambiente) podem produzir efeitos nocivos na saúde. Sendo assim, o objetivo deste estudo foi investigar a prevalência das queixas auditivas de diminuição auditiva, zumbido, otalgia, sensação de plenitude auricular, desconforto a sons intensos e dificuldade de compreensão de fala na população feminina não exposta a ruído. Trata-se de um estudo observacional, descritivo e transversal, realizado na cidade de João Pessoa/PB, com a participação de 539 mulheres, que não apresentavam exposição a ruído ocupacional. Foi realizada uma média ponderada, a fim de atribuir maior importância aos efeitos referidos como mais frequentes, considerando os seguintes pesos: 1 – nunca, 2 – raramente, 3 – às vezes, 4 – frequentemente, 5 – sempre. O projeto de pesquisa foi aprovado pelo Comitê de Ética em Pesquisa com Seres Humanos do Hospital Universitário Lauro Wanderley. As queixas auditivas mais referidas como percebidas “sempre” foram as queixas de incômodo a sons intensos (20,59%) e zumbido (2,41%). Já em relação à frequência “nunca”, destacaram-se as queixas de zumbido (43,04%) e otalgia (42,12%). Conclui-se que as queixas auditivas mais prevalentes entre as mulheres foram incômodo a sons intensos e dificuldade de compreensão de fala.

Bilindiği üzere sosyal güvenlik, dayanışma ilkesiyle bilinen bir kavramdır ve EYT yasası, yaşlılık aylığına hak kazanmada aynı yaş grubu içinde dahi önemli farklılıklar yaratmış olup bu çalışmanın konusunu, aynı yaş grubunda bulunan iki sigortalıdan birisinin işe giriş tarihine bağlı olarak yaşlı sayılması, diğerinin ise yaşlı sayılmaması oluşturmaktadır. Bu bağlamda çalışmanın amacı, aynı yaş grubunda bulunanların EYT yasasına tepkilerini www.eksisozluk.com sitesinde yazılanlar üzerinden kuşak içi dayanışma ve çatışma perspektifinden açıklamaktır. Çalışmada; Ekşi Sözlük’te EYT hakkında yazılan 103 başlık içinden araştırma konusu üzerine açılan 10 başlık ve bu başlıklar içerisinde en beğenilen girişler (sözlükteki ifadesiyle “entry”) içerik analizi yöntemiyle incelenmiştir. Analize göre başlıklar içerisinde ele alınan girişlerin 85’i (%78,7’si) EYT yasasına karşıt bir görüş belirtmektedir. Yine analizde girişler, 10 ana tema ve 1 öneri teması altında birleştirilmiştir. Bu analizde en çok ele alınan iki tema “kuşakiçi çatışma-dayanışma” ve “Adil/Adalet/Adaletsizlik/Eşitlik/Eşitsizlik/Hak/Haksızlık” temaları olmuştur.

En la Universidad Nacional de Loja se han realizado varias investigaciones sobre evaluación biológica con la técnica del elemento faltante, adaptada y validada por Valarezo y Guayllas que utiliza el tomate (Solanum lycopersicum L.) como planta indicadora, procedimiento relativamente rápido, eficiente y efectivo para detectar las carencias de nutrientes en el suelo, al eliminar sistemáticamente, de una fórmula nutritiva completa uno de los elementos. En Ecuador, la Red de Laboratorios de Suelos (RELASE) utiliza la solución extractora de Olsen Modificada para determinar los elementos presentes en el suelo; sin embargo, dicha solución es empleada de forma general para todos los suelos. Los resultados de los análisis químicos se deberían correlacionar con valores del peso de la biomasa seca; no obstante, en general, presentan ausencia de correspondencia. En estas consideraciones, se propuso explorar posibles relaciones mediante técnicas de análisis estadístico entre los resultados del laboratorio y el método del elemento faltante. Se recolectó datos de 12 investigaciones realizadas en las provincias ecuatorianas: Esmeraldas, Los Ríos, Zamora Chinchipe y Loja; se realizó cálculos de correlación entre altura y peso de la biomasa seca de la planta indicadora. Se evidenció falta de correlación entre los resultados del análisis químico del laboratorio con los resultados de la evaluación biológica; en el sector Pueblo Nuevo (Malacatos, Loja), se evidenció falta de correspondencia entre los resultados del análisis químico y la técnica del elemento faltante. En comparación con la solución extractora, la evaluación biológica, expresa de manera más confiable el contenido de nutrientes del suelo.

Los bosques secos de la provincia de Loja presentan un mejor grado preservación y es el hábitat ideal donde se desarrolla la especie Handroanthus chrysanthus (Jacq.) S.O.Grose, también conocida como “Guayacán”. Especie caducifolia, tiene un crecimiento que depende de factores biológicos y produce anillos de crecimiento anuales que contienen información vital para reconstruir la historia de su desarrollo, es por ello que el presente estudio analizó la dinámica de crecimiento a través de métodos dendrocronológicos de 16 individuos de H. chrysanthus provenientes de la parroquia Zapotillo al sur de Ecuador. Los resultados principales revelaron que la edad promedio de los Guayacanes fue de 113 años, con el individuo más longevo de 207 años (1812 y 2019), y el más joven de 72 años (1947 y 2019). El crecimiento diamétrico anual promedio fue de 1.46 mm/año, con una desviación estándar de ± 0.62 mm, indicando un crecimiento constante a lo largo de su vida. Lo que nos permite concluir que H. chrysanthus hasta una edad de 207 años continúa con una tendencia constante de crecimiento diamétrico anual.

La estimación del potencial melífero de seis apiarios en el recinto Quimis, es importante para comprender la importancia de conservar hábitats específicos y fomentar la apicultura sostenible. Esta investigación se realizó para determinar la diversidad de especies con potencial melífero. Se establecieron seis transectos de 50 x 4 m distribuidos en el bosque seco tropical, donde a través de un inventario se diagnosticó la diversidad florística existente en la zona; se elaboró un calendario foral basado en un análisis mensual (durante un año), de las especies que proporcionan néctar y polen. Se muestrearon 314 individuos pertenecientes a 20 especies vegetales, distribuidas en 20 géneros de13 familias. Los meses de mayor floración resultaron, junio, julio y agosto; Prosopis pallida, floreció durante siete meses en un año. Por su parte, Ceiba trischistandra, Iochroma arborescens, Convolvulus arvensis, Xenostegia mediana, Delonix regia, Eriotheca ruizii, Leucaena leucocephala, Vallesia glabra, Pithecellobium excelsum, Capparicordis crotonoides y Colicodendron scabridum, destacaron por producir néctar y polen. La producción de miel está influenciada por la disponibilidad de néctar proveniente de individuos de Cordia lutea y Cynophalla sclerophylla. Apis mellifera (abeja), demostró una clara inclinación hacia fores de especies del bosque seco tropical, la cuales fueron mencionadas anteriormente, lo que concluye la importancia de preservar hábitats específicos para garantizar la supervivencia de estas plantas y, en consecuencia, las abejas.

El pastoreo de especies pequeñas en la eliminación de arvenses es una alternativa al uso de agroquímicos. Sin embargo, especies como borregos y chivos pueden causar daños significativos en las plantaciones, causando disminución en los rendimientos esperados. Además, entre los beneficios que se obtienen por el pastoreo de animales son: fertilización por excretas y orines, beneficio económico al disminuir gastos de jornales y la venta de borregos; aunado al método amigable con el ambiente para eliminar arvenses.

Los quesos artesanales elaborados con leche de cabra no solo constituyen una valiosa fuente de macronutrientes, como proteínas y lípidos, sino que también son elementos fundamentales de nuestro patrimonio cultural. En el Estado de Veracruz, existen zonas propicias para la caprinocultura debido a las condiciones ambientales y vegetación favorables. Actualmente, en municipios como Tatila, Xico y Coatepec, entre otros, se producen artesanalmente subproductos derivados de la leche de cabra, como los quesos. Estos quesos no solo son fundamentales en la dieta, sino que también aportan identidad cultural a los lugares donde se elaboran. Los quesos artesanales se caraterizan por su proceso de elaboración heterogéneo, lo que resulta en una amplia gama de calidades sensoriales. Se ha observado que la variación en factores del proceso de elaboración, como el tiempo de maduración y el de prensado, pueden dar lugar a quesos con distintas calidades y caracteristicas. Por ejemplo, los diferentes tiempos de maduración pueden generar diferentes atributos sensoriales, mientras que los tiempos de prensado pueden influir en la microestrura de los quesos. Desde el punto de vista de producción y el posicionamiento del producto en los mecados, la interacción entre el tiempo de maduración y el de prensado puede ser un factor determinante para la preferencia o el rechazo de los quesos por parte de los consumidores. Basándose en lo anterior, el objetivo de esta investigación es caracterizar quesos artesanales de cabra con diferentes tiempos de maduración y prensado.
FEATURES OF THE SETTLEMENT OF INTERNATIONAL CYBER DISPUTES THROUGH ADR IN THE CONTEXT OF THE LEGISLATION OF THE BRICS COUNTRIES
Authors: Rustambekov Islambek
Published: July 2024

This paper examines the comparative effectiveness of various alternative dispute resolution (ADR) methods in resolving international cyber disputes. Drawing on a review of academic literature, analysis of practical case studies and statistical data, it identifies key procedural strengths and limitations of arbitration, mediation, ombudsmen, and online dispute resolution for common cyber conflict scenarios. It concludes on the optimal tailoring of different ADR techniques for cybercrime, hacking attacks, data breaches, and e-commerce disputes. The paper proposes multiple innovations to enhance cyber ADR efficacy, including hybrid models, specialized procedural standards, and enforcement mechanisms. It discusses integrating ADR into national cybersecurity strategies using the BRICS platform as an example. The research aims to inform optimization of flexible, confidential, and technically expert out-of-court approaches to manage the proliferation of cross-border cyber disputes.
Key findings show mediation’s utility for cybercrime across jurisdictions but need for law enforcement coordination. International arbitration is appropriate for cyber B2B disputes while ombuds aid consumer recourse. Early neutral evaluation assists cybersecurity breach diagnosis but requires enforcement. Tailored arbitration rules, substantively flexible guidelines, and incentivizing voluntary ADR adoption are advised.

Bu çalışmanın konusunu Yargıtay Hukuk Genel Kurulu’nun 01.12.2022 tarihli kararı oluşturmaktadır. Kemal Sunal kararı olarak da isimlendirilen bu karar medya tarafından da takip edilen ve sonuçları basında kendisine yer bulmuş bir karardır. Karar kanaatimizce teknolojik gelişmenin ve yayın faaliyetlerinin çeşitlenmesinin, şekil değiştirmesinin fikri haklar alanına etkilerini göstermesi yönüyle de inceleme değerdir. Bu çerçevede işbu çalışmada karardaki hukuki sorun tespit edildikten sonra kararın tarihçesi kısaca açıklanmıştır.
İnceleme konusu kararın temelinde icracı sanatçının bağlantılı hakları yer almaktadır. Teknolojik imkânların çeşitlenmesi, fikri haklar alanını da doğrudan etkilemiştir. Böylece hakkın içeriğinin yeniden tanımlanması gündeme gelmiştir. 5856 sayılı FSEK, eser sayılabilecek bir fikri ürünü meydana getirmeyen bazı çalışmaları da koruma altına almıştır. Bu haklar ise bağlantılı hak olarak isimlendirilmektedir. İşbu çalışmada da bağlantılı haklar düzenlemesinin bir diğer ifadeyle Kanun değişikliğinin telif hakkının içeriğine etkisinin, değişiklik öncesi tasarruflara etkisi hem borçlar hukuku hem de telif hukuku yönüyle Yargıtay Hukuk Genel Kurulu’nun kararı çerçevesinde incelenmiştir. Buna ek olarak fikri haklara yönelik tasarruflara Kanun hükümlerinin zaman bakımından nasıl uygulanacağı sorusuna da temas edilmiştir.
YABANCI UNSURLU FİKRÎ MÜLKİYET UYUŞMAZLIKLARINDA “KORUMA ÜLKESİ HUKUKU” (LEX LOCI PROTECTIONIS) KAVRAMININ BELİRSİZLİĞİ

Published: July 2024

Milletlerarası Özel Hukuk ve Usul Hukuku Hakkında Kanun (MÖHUK) m. 23/1 hükmüne göre fikrî mülkiyete ilişkin haklar, koruma ülkesi hukukuna (lex loci protectionis) tâbidir. Ancak bu noktadaki esas sorun, lex loci protectionis terimiyle kastedilen hukukun, hangi ülke hukuku olduğudur. Lex loci protectionis’in davaya bakan mahkemenin hukuku (lex fori) olabileceğini ifade edenler olduğu gibi, ihlâl yeri hukuku (lex loci delicti) veya fikrî mülkiyet hakkının menşe yeri (lex originis) olduğunu kabul eden yazarlar da vardır. Türk öğretisindeki yaklaşım lex loci protectionis’in davacıya tek taraflı bir hukuk seçimi imkânı verdiği yönündedir. Buna göre birden fazla devlette korunan fikrî hak, bu devletlerde aynı kişi tarafından ihlâl edilmişse davacı, koruma ülkesi hukuklarından birisinin uygulanmasını seçebilir. Kanaatimizce bu yöndeki bir yaklaşım fikrî mülkiyet haklarının mülkîliği ilkesine uygun düşmemektedir. Çalışmamızda, karşılaştırmalı hukuktaki görüşler ve mahkeme kararlarından hareketle lex loci protectionis’in özellikle lex loci delicti, lex originis ve lex fori ile farkı açıklanacak ve lex loci protectionis’in ülkesellik ilkesi ile uyumlu anlamı ortaya konulmaya çalışılacaktır.
