Authors: Zhang Zhezhe , Guo Baohua , Cheng Shengjin , Zhong Pengbo , Zhu Chuangwei
Published: September 2024

In order to study the shear mechanical properties of rock joint under different unloading stress paths, the RDS-200 rock joint shear test system was used to carry out direct shear tests on concrete joint specimens with five different morphologies under the CNL path and different unloading stress paths. The unloading stress paths include unloading normal load and maintaining constant shear load (UNLCSL), unloading normal load and unloading shear load (UNLUSL), unloading normal load and increasing shear load (UNLISL). The results show that the peak shear strength, cohesion, internal friction angle, pre-peak shear stiffness and residual shear strength of concrete joints under CNL path increases with the increasing JRC and normal stress. Under the UNLCSL path, under the same initial shear stress τ1, instability normal stress σi decreases with the increasing JRC, and normal stress unloading amount Δσn increases with the increasing JRC. Under the same JRC, σi increases with the increase of τ1, and Δσn decreases with the increasing τ1. Under the same JRC and σi, τi is significantly smaller under the UNLCSL path than the CNL path. Under the same JRC, the cohesion under the UNLCSL path is less than the CNL path, and the internal friction angle is higher than that the CNL path. Under the same JRC and σi, τi is the largest under the path of CNL and UNLISL, followed by the UNLCSL path, and τi under the UNLUSL path is the smallest. Compared with the CNL path, the variation range of the specimen internal friction angle is within 3% while the average decrease percentage of the specimen cohesion reaches 37.6% under the UNLCSL path, UNLISL, and UNLUSL. Therefore, it can be inferred that the decrease in cohesion caused by normal unloading is the main reason for the decrease in joint instability shear strength. After introducing the correction coefficient k of cohesion to modify the Mohr-Coulomb criterion, the maximum average relative error after correction is only 3.5%, which is significantly improved compared with the maximum average relative error of 56.9% before correction. The research conclusions can provide some reference for the accurate estimation of shear bearing capacity of rock joints under different unloading stress paths, which is of great significance to the stability evaluation and disaster prevention of rock mass engineering.
Buying inferior to selling: Explore the impact of transaction direction on the effects of related-party transactions
Authors: Li Shuang , He Jie
Published: September 2024

Throughout, the effects of related-party transactions (RPTs) have been a hot topic in financial markets and corporate governance research. This paper analyzes the theoretical foundation of the effects of RPTs and constructs a new indicator, the quasi-profit margin, to assess the effects of RPTs by studying their impact on the quasi-profit margin. Based on the information asymmetry between transaction parties and the information screening theory, the paper proposes the buying inferior to selling theory, systematically explaining the impact of transaction direction on the effects of RPTs. Subsequently, using panel data from Chinese A-share listed companies from 2016 to 2021, the paper constructs fixed-effects models and conducts empirical studies from both exogenous and endogenous perspectives, employing estimation methods such as high dimensional fixed effects method, two-stage least squares method, and three-stage least squares method. The research indicates that RPTs of Chinese A-share listed companies generally exhibit a tunneling effect, and the transaction direction significantly affects the effects of RPTs. The higher the proportion of RPTs conducted as sellers to the total RPTs, the smaller the overall tunneling effect of the RPTs. This study has implications for reducing the tunneling risk of RPTs and improving corporate governance for listed companies, as well as providing some references for financial regulatory authorities to identify and rectify illegal RPTs.

Background

In times of demographic change and an immense shortage of qualified personnel in emergency medical services, telemedicine could offer more efficient solutions for better care. Given the community-based nature of emergency services, local communities play an important role. This study explored the expectations of healthcare professionals and volunteers for telemedicine tools in prehospital emergency medicine.

Methods

This mixed-methods study was conducted in the rural region of Burgenland in Austria with stakeholders of the local emergency medical service in two focus groups (13 participants) and 99 quantitative questionnaires.

Results

Combining quantitative and qualitative data, we found that a majority of respondents (almost 80%) already experienced basic telemedicine and consider it valuable. In particular, there is a strong expectation for diagnostic support and inquiries related to potential hospitalization. Findings from two focus groups emphasized the importance of cultivating an improved learning culture, developing a specific mindset, and refining soft skills. The optimal telemedicine solution includes a knowledgeable and experienced tele-emergency physician coupled with user-friendly technology.

Conclusion

To be clear about the expectations of stakeholders, it is essential to involve all stakeholders right from the beginning. The solution should prioritize the integration of existing structures and be seamlessly incorporated into an evolving learning culture, while also fostering the necessary mindsets alongside educational aspects.

Hemodynamics in Doppler ultrasonography
Authors: Lee Jongmin
Published: September 2024

The cardiovascular system operates through complex hemodynamic processes involving pulsatile blood flow, varying viscosity, and the branching architecture of vessels. Interactions between blood flow and the vascular wall, which are characterized by shear and normal stress, along with wall stiffness, are crucial for maintaining vascular health. Doppler ultrasonography is a highly valuable noninvasive tool for assessing these hemodynamic parameters, enabling the measurement of key indices such as blood flow velocity, flow patterns, wall shear stress, and wall stiffness. This paper emphasizes the clinical significance of these indices and methods of measuring them using Doppler ultrasonography while addressing potential challenges. Accurate interpretation of these measurements is vital for reliable cardiovascular diagnostics and effective clinical decision-making.

In an effort to create tujuan, Islam offers the compatibility between couples (kafa'ah), which matching in the social level or the same confidence. Islam is not too make a problem out of social level such as mixed marriages in Indonesia between the Indonesians and foreigners. Other difference is the case with religious marriage between Muslims and non-Muslim (especially of the Book), Islam clearly arranged. Although a statement of confidence can not be guaranteed the realization of the purpose of marriage, not all couples of like mind lives in harmonic, harmony, and peace, but sometimes couples of different religions living harmoniously, consistent and peaceful. This does not mean your wedding different confidence is better than on religion. If you look back wedding vulnerable religious conflict differently, both on the question of worship, religious and other children. Other than that in Indonesia and religious law forbids it.[Setiap perkawinan bertujuan untuk membina keluarga sakinah mawaddah dan rah}mah. Dalam usaha mewujudkan tujuan tersebut, Islam menawarkan keserasian antara pasangan (kafa>’ah), yakni sepadan baik dalam strata sosial ataupun keyakinan yang sama.

Lain halnya dengan perkawinan beda agama antara Muslim dan non-Muslim (khususnya Ahli Kitab), Islam mengaturnya dengan jelas. Walau kenyataannya keyakinan tidak bisa menjadi jaminan terwujudnya tujuan perkawinan, tidak semua pasangan yang seiman kehidupannya harmonis, selaras, dan damai, malah kadang kehidupan pasangan yang berbeda agama lebih harmonis, selaras, dan damai.

Normatively, before there marriage hold certain processes that will be undertaken of a man and women, including: process ta’aruf, khitbah, followed by the ceremony. Felix Siauw has another opinion about the sequence of theprocesses that are undertaken before marriage. He argues that the process of ta’aruf khitbah precedence, so khitbah first and then ta’a>ruf. He reasoned that the majority of young people who want to get a potential partner in the present more follow it with the first courtship. The majority reasoned that premarital courtship as a venue for exploration, to better get to know each other’s personalities. It is considered to be vulnerable to various immoral acts by him, and therefore he would prefer putting khitbah than ta’a>ruf, in addition to that he also has some concepts in ta’aruf. Ustad Felix Siauw have a concept in ta’aruf. This paper will explain the concept Felix Siauw in terms of Mas}ah}lah and Maqa>s}id asy-Syari>’ah.[Secara normatif, sebelum melangsungkan perkawinan terdapat proses-proses tertentu yang akan dijalani seorang pria maupun wanita, diantaranya: proses ta’aruf, khitbah, dilanjutkan dengan akad nikah.

One of the most significant biotic constraints that wheat production faces is weed infestation. Wheat is infested with different weeds that cause yield losses (up to 100%) that vary based on the type of weed, their density, and the environmental conditions. Chemical weed control is the most common method to control weeds in wheat. However, widespread herbicide resistance (>365 cases worldwide) has challenged the sustainability of this method. Use of nanoherbicides is a promising strategy to cope with the issue of herbicide resistance. To achieve weed control conditions during the whole growing season, nanoformulations of herbicides are a delivery strategy that involves covering an active component with various materials that vary in size from nano to nanoscale and then releasing the substance in a controlled manner. Nanoherbicides prevent leaching and volatilization of active components and premature degradation through photolysis, hydrolysis, and biodegradation. According to studies, nanoencapsulation of herbicides produces more targeted and less hazardous agricultural formulations. Using nanoherbicides in lower concentrations is beneficial. It lessens the long-term impacts of herbicide residues in wheat fields and the toxicity of these herbicides to the environment. It is also beneficial in eliminating the weeds without ever interacting with the crop plants, which eventually results in a greater wheat yield. This review provides a comprehensive overview of the emerging field of utilizing nanoparticles (NPs) in herbicides for effective weed management in wheat crops. This article explores the novel approach of integrating NPs with herbicidal agents, highlighting their potential benefits and challenges. The review also addresses the current state of research, recent advancements, and potential future directions in this evolving area of agricultural science.
Effects of thyroid hormones in skeletal muscle protein turnover
Authors: Nappi Annarita , Moriello Caterina , Morgante Maria , Fusco Ferdinando , Crocetto Felice , Miro Caterina
Published: September 2024

Thyroid hormones (THs) are critical regulators of muscle metabolism in both healthy and unhealthy conditions. Acting concurrently as powerful anabolic and catabolic factors, THs are endowed with a vital role in muscle mass maintenance. As a result, thyroid dysfunctions are the leading cause of a wide range of muscle pathologies, globally identified as myopathies. Whether muscle wasting is a common feature in patients with hyperthyroidism and is mainly caused by THs-dependent stimulation of muscle proteolysis, also muscle growth is often associated with hyperthyroid conditions, linked to THs-dependent stimulation of muscle protein synthesis. Noteworthy, also hypothyroid status negatively impacts on muscle physiology, causing muscle weakness and fatigue. Most of these symptoms are due to altered balance between muscle protein synthesis and breakdown. Thus, a comprehensive understanding of THs-dependent skeletal muscle protein turnover might facilitate the management of physical discomfort or weakness in conditions of thyroid disease.

Herein, we describe the molecular mechanisms underlying the THs-dependent alteration of skeletal muscle structure and function associated with muscle atrophy and hypertrophy, thus providing new insights for targeted modulation of skeletal muscle dynamics.

Objectives

To evaluate the use of ureteral access sheaths (UAS) in reducing operative time and complications, as well as improving stone-free rates (SFR), while assessing their overall safety and efficiency.

Methods

Data regarding 234 patients who underwent retrograde intrarenal surgery (RIRS) for stones up to 3 cm between January 2017 and March 2020 were retrospectively analyzed. About 52.5 % of procedures were performed utilizing a UAS. Differences in operative time, fluoroscopy time, stone-free rate, and complications were analyzed between procedures with and without UAS and stratified, according to stone burden size, into three groups (Group A: 0.5–1 cm; Group B: 1–2 cm; Group C: 2–3 cm).

Results

Operative time, fluoroscopy time, and residual fragments size were lower in RIRS without UAS, respectively, 54.27 ± 24.02 vs. 62.23 ± 22.66 min (p=0.010), 2.72 ± 0.89 vs. 4.44 ± 1.67 min (p<0.0001), and 3.85 ± 0.813 vs. 4.60 ± 0.83 mm (p=0.011). Considering stone burden, operative time was lower in RIRS without UAS for Group A (36.40 ± 8.555 vs. 46.05 ± 6.332 min) (p<0.0001) while higher for Group B (60.39 ± 18.785 vs. 50.14 ± 5.812 min) (p=0.002). Similarly, fluoroscopy time was lower in RIRS without UAS in every group, respectively, 2.11 ± 0.34 vs. 2.74 ± 0.57 min (p<0.0001), 2.94 ± 0.51 vs. 4.72 ± 0.37 min (p<0.0001), and 3.78 ± 1.26 vs. 6.79 ± 1.17 min (p<0.0001). Only Group C had a statistically significant difference in residual fragment size without UAS (3.89 ± 0.782 vs. 4.75 ± 0.886 mm) (p=0.050).

Conclusions

UAS should be carefully evaluated considering the increased fluoroscopy time and the differences in operative time related to different stone burdens.

Published: September 2024

In this article, we introduce and study a new class of higher-order fractional q-difference equations involving Riemann-Liouville q-derivatives with dual hybrid terms, supplemented with nonlocal multipoint q-integral boundary conditions. The existence of a unique solution to the given problem is shown by applying Banach’s fixed point theorem. We also present existing criteria for solutions to the problem at hand with the aid of Krasnoselskii’s fixed point theorem and Leray-Schauder’s nonlinear alternative. Illustrative examples are given to demonstrate the application of the obtained results.

Human and mouse dorsal root ganglia (hDRG and mDRG) neurons are important tools in understanding the molecular and electrophysiological mechanisms that underlie nociception and drive pain behaviors. One of the simplest differences in firing phenotypes is that neurons are single-firing (exhibit only one action potential) or multi-firing (exhibit 2 or more action potentials). To determine if single- and multi-firing hDRG neurons exhibit differences in intrinsic properties, firing phenotypes, and AP waveform properties, and if these properties could be used to predict multi-firing, we measured 22 electrophysiological properties by whole-cell patch-clamp electrophysiology of 94 hDRG neurons from six male and four female donors. We then analyzed the data using several machine learning models to determine if these properties could be used to predict multi-firing. We used 1,000 iterations of Monte Carlo cross-validation to split the data into different train and test sets and tested the logistic regression,k-nearest neighbors, random forest, support vector classifier, and XGBoost machine learning models. All models tested had a >80% accuracy on average, with support vector classifier, and XGBoost performing the best. We found that several properties correlated with multi-firing hDRG neurons and together could be used to predict multi-firing neurons in hDRG including a long decay time, a low rheobase, and long first spike latency. We also found that the hDRG models were able to predict multi-firing with 90% accuracy in mDRG neurons. Understanding these properties could be beneficial in the elucidation of targets on peripheral sensory neurons related to pain.
Differential Encoding of Two-Tone Harmonics in the Male and Female Mouse Auditory Cortex
Authors: De Amiyangshu , Agarwalla Swapna , Kaushik Raghavendra , Mandal Debdut , Bandyopadhyay Sharba
Published: September 2024

Harmonics are an integral part of music, speech, and vocalizations of animals. Since the rest of the auditory environment is primarily made up of nonharmonic sounds, the auditory system needs to perceptually separate the above two kinds of sounds. In mice, harmonics, generally with two-tone components (two-tone harmonic complexes, TTHCs), form an important component of vocal communication. Communication by pups during isolation from the mother and by adult males during courtship elicits typical behaviors in female mice—dams and adult courting females, respectively. Our study shows that the processing of TTHC is specialized in mice providing neural basis for perceptual differences between tones and TTHCs and also nonharmonic sounds. Investigation of responses in the primary auditory cortex (Au1) from in vivo extracellular recordings and two-photon Ca2+imaging of excitatory and inhibitory neurons to TTHCs exhibit enhancement, suppression, or no-effect with respect to tones. Irrespective of neuron type, harmonic enhancement is maximized, and suppression is minimized when the fundamental frequencies (F0) match the neuron's best fundamental frequency (BF0). Sex-specific processing of TTHC is evident from differences in the distributions of neurons’ best frequency (BF) and best fundamental frequency (BF0) in single units, differences in harmonic suppressed cases re-BF0, independent of neuron types, and from pairwise noise correlations among excitatory and parvalbumin inhibitory interneurons. Furthermore, TTHCs elicit a higher response compared with two-tone nonharmonics in females, but not in males. Thus, our study shows specialized neural processing of TTHCs over tones and nonharmonics, highlighting local network specialization among different neuronal types.
Effect of traditional gold mining to surface water quality in Murung Raya District, Central Kalimantan Province
Authors: Wilopo W , Resili R , Putra D P E
Published: September 2024

There are many locations for traditional gold mining in Indonesia. One of these is in Murung Raya District, Central Kalimantan Province. Mining activities involving the application of traditional gold processing technology have a high potential to pollute the environment, especially surface water. Therefore, this study aims to determine the impact of gold mining and processing on surface water quality around the mine site. Based on the results of field surveys and laboratory analysis, our data shows that the concentration of mercury (Hg) and Cyanide (CN) has reached 0.3 mg/L and 1.9 mg/L, respectively, in surface water. These values exceed the drinking water quality standards of Indonesia and WHO. Many people who live in the mining area use surface water for daily purposes including drinking, cooking, bathing and washing. This scenario is very dangerous because the effect of surface water contamination on human health cannot be immediately recognized or diagnosed. In our opinion the dissemination of knowledge regarding the treatment of gold mining wastewater is urgently required so that the quality of wastewater can be improved before it is discharged into the environment
Characterization of phosphate solubilizing bacteria isolated from Pb contaminated soils and their potential for dissolving tricalcium phosphate
Authors: Susilowati L E , Syekhfani S
Published: September 2024

Phosphorus solubilizing bacteria (PSB) enhances P availability in soils through dissolving inorganic P pools. The characteristics of PSB and the potential of three Pb tolerant phosphate solubilizing rhizobacteria, i.e. Pseudomonassp, Bacillus sp., and Actinomycites sp. were evaluated. PSB were isolated from soil samples contaminated with 300 and 500 mg Pb/kg after incubation for 30 days. Phosphate solubilizing bacteria were screened on for phosphate solubilisation ability in Pikovskaya agar medium (PA). In addition, two of the three indentified PSB strains (Pseudomonas sp. and Bacillus sp.) were characterized for their ability to solubilize tricalcium phosphate in Pikoskaya broth (PB) and also were examined their growth during culture medium incubation. The isolates exhibited different phosphate solubilization index, ranging from 1.87 to 2.98. Pseudomonas sp. had the highest ability to solubilize tricalcium phosphate: 9.82 mg P/ L and 12.23 mg P/ Lin Pikoskaya broth following the addition of 4 mg Pb/L and 2 mg /Pb L, respectively.Â
The potential of legume tree prunings as organic matters for improving phosphorus availability in an acid soil
Authors: Wahyudi I , Handayanto E
Published: September 2024

A study that was aimed to elucidate roles of Gliricidia sepium and Tithonia diversifolia prunings and their extracted humic and fulvic acids on improving phosphorus availability and decreasing aluminum concentration in an Ultisol was conducted in a glasshouse. Thirteen treatments consisting of two prunings, six rates of pruning application (5, 7.5, 10, 20, 40 and 80 t/ha) and one control (no added prunings) were arranged in a randomized block design with four replicates. Each mixture of prunings and soil was placed in a pot containing 8 kg of soil and maize of Srikandi cultivar was grown on it for 45 days. At harvest, soil pH, P content and aluminium concentration were measured. Results of the glasshouse experiment showed that application of Gliricidia and Tithonia prunings significantly increased soil pH, reduced Alo concentration, increased Alp content, increased P availability, and increased P taken up by maize grown for 45 days. The optimum rate of both Gliricidia and Tithonia pruning should be 40 t/ha. However, at the same rate, optimum production gained by Tithonia would be higher than that of Gliricidia.

Objective of the research was to study the effect mycorrhiza on growth and yield of tomato. The experiment was conducted in screen house 14 m x 10.5 m, in Pasuruan on November 2013 until March 2014, The experiment was conducted as a factorial randomized complete design. The first factor was dose of mycorrhiza (without mycorrhiza, 5 g mycorrhiza, 10 g mycorrhiza, and 20 g mycorrhiza). The second factor was the salinity stress level (without NaCl, 2500 ppm NaCl, 5000 ppm NaCl, and 7500 ppm NaCl). The results showed that salinity stress at the level 7500 ppm decreased the amount of fruit by 30.84% and fresh weight per hectare decreased by 51.72%. Mycorrhizal application was not able to increase the growth and yield in saline stress conditions; it was shown by the level of infection and the number of spores on the roots of tomato plants lower the salinity level 5000 ppm and 7500 ppm. But separately, application of 20 g mycorrhiza enhanced plant growth, such as plant height, leaf area, leaf number and proline. Application of 20 g mycorrhiza increased the yield by 35.99% Â

Returning and addition of organic material to soil is a key to protecting the soil, plants, and the environment. A study aimed to elucidate the effect of residual biomass application on some indicators of soil physical properties, abundance of earthworms and soil microbial activities was conducted in Kebun Percobaan (KP) Natar, BPTP Lampung from February to July 2017. The treatments were three types of crops biomass residues, i.e., maize stover, rice straw, and soybean stover (fresh or compost). The dosage rates were 0, 2.5, 5.0, 7.5, and 10 t/ha. The treatments were arranged in a randomized block design with three replicates. Upland rice (Inpago 9 variety) was planted after two weeks application of biomass residues treatments. The results showed that application of crops biomass residues improved bulkdensity and significantly increased soil water content at the high dose of biomass residues (7.5 or 10 t/ha). The amount and weight of earthworms with added of compost biomass was significantly correlated with soil water content (r values 0.491 and 0.376, respectively). The dose of biomass residues had a significant effect on soil respiration that the highest soil respiration was obtained in maize compost biomass treatment (at 12 weeks observation) was 31.7 and rice straw compost (at 8 weeks observation) which was 30.19 mg/hour/m2 C-CO2.

The establishment of the Eucalyptus urophylla plantation has a potential contribution to the improvement of dryland ecosystem productivity in East Nusa Tenggara. However, the productivity of E. urophylla stand in this area is rarely documented even though it has been managed for more than 20 years. This study was directed to evaluate the growth performance, biomass accumulation, and carbon storage in E. urophylla plantation managed by Timor Tengah Selatan Forest Management Unit (FMU). Data were collected by a field survey using N-trees sampling method. Results demonstrated the mean tree density of E. urophylla in this area was 182 trees/ha with an average stand volume of 150.12 m3/ha. The mean annual increment in volume varied from 1.83 to 19.45 m3/year. The mean biomass accumulation and carbon storage in E. urophylla plantation approached 171.76 and 52.25 Mg/ha. Around 65% of total biomass and carbon storage were accumulated in the stem. Interestingly, the relative contribution of the stem to total biomass increased slowly with diameter class increasing while the dissimilar trend was observed in root, branch, and foliage. Based on the results, this study confirmed that the existence of E. urophylla plantation could increase the productivity of dryland ecosystem in East Nusa Tenggara.

L'histoire du roman L'Argent d'Émile Zola raconte la lutte de Saccard pour bâtir son entreprise avec Hamelin. Saccard qui a vraiment l'ambition de gagner beaucoup d'argent en peu de temps, il veut aussi vaincre Gundermann, son rival. En fait, l'histoire de ce roman parle de la finance sous le Second Empire français et d'autres événements liés aux réalités sociales de cette époque. Certains événements historiques et importants contenus dans le roman sont des réalités sociales. Cette recherche identifie les réalités sociales présentées dans le roman en utilisant les trois concepts de base de Lucien Goldmann en structuralisme génétique. L'objet matériel examiné dans cette recherche est le roman L'Argent d'Émile Zola. La méthode d'analyse utilisée dans cette recherche est la méthode descriptive analytique, et les techniques d'analyse utilisées dans cette recherche sont la technique d'analyse du contenu latent et la technique de communication.

Ce roman raconte l’histoire d’un adolescent nommé Jun qui s’enfuit de chez lui et vit dans la rue parce qu’il veut oublier sa famille. C’est alors que Jun rencontre un maître du sumo nommé Shomintsu qui agira en tant que mentor pour l’aider à changer le cours de sa vie. La chercheuse utilise la théorie du psychologie transpersonnelle d’Abraham Maslow pour analyser ce roman. Cette étude vise à analyser le processus d’accomplissement et les caractéristiques du dépassement de soi trouvés dans Jun. La méthode d’analyse utilisée dans cette recherche est la méthode analytique descriptive qui est effectuée en décrivant les faits, puis l’analyse est suivie. Les techniques d’analyse de données utilisées sont la technique d’analyse de contenu latent et la technique communication.Les conclusions obtenues montrent qu’il y a six hierarchies de besoins que Jun a satisfaits dans le processus d’atteindre la transcendence c’est, les besoins physiologiques, les besoins de sécurité, les besoins d’appartenance et d’amour, les besoins d’estime et la réalisation de soi. Le processus est complete par la satisfaction d’un besoin, c’est dépassement de soi. Ensuite, l’auto-transcendance caractéristique de Jun a eu un effet profond sur sa vie. Ces caractéristiques n’apparaissent pas seulement, mais font partie du personage principal formé à partir de son parcours de vie.

Published: September 2024

L'utilisation de supports audiovisuels pour apprendre des langues étrangères n'est pas rare. Il existe de nombreux processus d'apprentissage en ligne qui mettent en œuvre des techniques d'apprentissage audiovisuelles et qui sont considérés efficaces. Cet article traite de l'efficacité des séries Netflix comme moyen d'apprentissage des langues étrangères pour les étudiants du programme d'études françaises de l'université d'État de Jakarta. Après avoir effectué une évaluation comparative de la compétence linguistique en français avant et après avoir regardé la série française Netflix sur les sujets de recherche, on constate que la série Netflix est capable de fournir une assez bonne exposition à un nouveau vocabulaire en langue étrangère pour ses téléspectateurs. Cependant, cette exposition bien accueillie ne correspond pas à la compétence linguistique des sujets de recherche. Les compétences linguistiques en français des téléspectateurs qui ont regardé la série francophone Family Business sur Netflix n'ont pas changé de manière significative, par conséquent Netflix s'est avéré ne pas être un moyen efficace d'apprentissage des langues étrangères pour les apprenants de langues étrangères.

Cette recherche examine les idiomes français qui sont formés par des mots culturels dans le livre Les Expressions Idiomatiques par Chollet et Robert. Les équivalences en indonésien sont utilisées Kamus Ungkapan Bahasa Indonesia (Chaer, 1997). Le mots des éléments culturels et leur catégorie culturelle d’équivalence sont basés sur la théorie de Newmark. Les buts de cette étude sont trouver les équivalences culturelles de l’idiome français et ceux indonésien puis savoir quels types d'éléments culturels existent des idiomes français aux idiomes indonésiens. La méthode de collecter des données est la méthode d’écoute avec la technique basée est tapotement et les techniques avancées sont la technique de l’observation sans participation et prise de note. Ensuite, en tant que l’outil d’analyse des données, la chercheuse utilise la méthode équivalence avec la technique basée trier l’élément déterminant et la technique avancée est la technique de comparer les similitudes et les différences d’élément. D’après l’analyse des données, il y a 43 idiomes français qui ont le mot culturel. Ces idiomes ont quelques catégories basées sur l’équivalence en indonésien, ce sont (1) le même élément culturel entre les idiomes français et ceux indonésien en utilisant beaucoup de l’élément écologique (2) le différent élément culturel entre les idiomes français et ceux indonésien (3) Il n’y a pas d’équivalences pour le mot culturel en indonésien parce qu’ils sont principalement formés par des mots formant de la partie du corps.

La tristesse prolongée vécue par Line est liée au concept de Sigmund Freud de la tristesse causée par la perte de l'objet de l'amour. Dans cette étude, l'objet matériel choisi est un roman intitulé Les Os des Filles de Line Papin et l'objet formel de cette recherche est le concept de tristesse qui est conforme à l'étude de la mélancolie de Sigmund Freud. Cette étude vise à révéler les facteurs qui font que le personnage de Line éprouve des troubles psychologiques en utilisant la théorie de la mélancolie de Sigmund Freud. Cette étude utilise des méthodes analytiques descriptives et des techniques d'analyse de contenu pour décrire l'état psychologique du personnage de Line. La séparation du personnage de Line de son objet d'amour a été le principal facteur qui lui a fait vivre la mélancolie. Elle a également pu se remettre de ce trouble dépressif après le désir de guérir en elle et l'émergence d'un cœur brisé qui lui a fait réaliser que l'objet de l'amour n'était plus le sien.
