Reception of transnational TV in South Korea through fan videos: Pachinko
Get PDFThis article explores Korean audience engagement with and reception of video reviews on YouTube, taking as a case study Pachinko (2022), Apple TV+’s screen adaptation of the New York Times bestseller written by Lee Min Jin. Given the importance of fragmentary redistribution of media materials in this streaming era that enables a faster bottom-up sharing of media than ever before, fan video offers an important scholarly resource for understanding reception of translated media. Many viewers go to streaming platforms like YouTube for a preview or fast viewing, but how these fan created materials influence subsequent media consumption and reception received scant attention particularly in the Korean context, especially in relation to translated media. Focusing on three video reviews about Pachinko Season 1 with over one million views on YouTube in South Korea, this paper analyzes the extent to which audience creators intervene in, and engage with, the production and circulation of translated media and how ordinary audiences receive them
Compact and directional dual band antenna with low mutual coupling MIMO configuration for mm-wave communication
Get PDFA compact dual band antenna and its multiple input multiple output (MIMO) configuration is presented in this
article to meet the requirements of devices operating in mm-wave band spectrum of 28 GHz and 38 GHz.
Wideband behavior is achieved using a modified T-shaped radiator loaded with stubs while the compactness in
structure is achieved by deploying various stubs. The antenna comprises of 15 × 15 mm2 which corresponds to
1.4λ0 × 1.4λ0, where λ0 represents the lower resonating frequency of 28 GHz. Broadband behavior is observed at
both targeting frequencies of 28 GHz and 38 GHz with respective measured bandwidth of 22.5–29.7 GHz (25.7
%) and 34.8–44.8 GHz (20.4 %) and peak gain of 8.9 dBi and 8.7 dBi. The proposed work offers directional and
stable radiation patterns at both pass band regions. Moreover, to fulfill the need of MIMO system, the antenna
design is further extended to its 2 × 2 MIMO configuration by placing the antennas orthogonal to each other. This
configuration results in low mutual coupling of < -20 dB, without utilizing any decoupling structure, resulting in
simple structured antenna which reduces the fabrication errors for mass production. Along with that the proposed MIMO antenna offers strong performance parameters having measured envelope correlation coefficient
(ECC) <0.2, measured diversity gain (DG) of > 9.75. Furthermore, the comparison with literary works highlights
the novelty of the presented work by offering dual-band coverage globally for 5G applications having compact
size, high gain and stable radiation patterns
The firm-level and aggregate effects of corporate payout policy
Get PDFThis paper presents a novel study on the significance of corporate payout policy in shaping firms’ financial decision-making and, in turn, the macroeconomy. To this end, we add to the literature by allowing households and firms to choose share buybacks optimally. We then explore the implications of various shocks commonly affecting them, such as dividend income, investment, and tax shocks. The latter include corporate income, capital gains, and dividend income taxes. We find that the model predictions cohere well with the data when applying the non-policy shocks. We also find that tax reform’s aggregate and welfare effects are overstated when share buybacks are not optimally chosen as assumed in the relevant literature
Hybrid delamination of silver contacts from c-Si solar cells: a low environmental impact recycling approach
Get PDFAs deployment of photovoltaic (PV) systems intensify amidst the shift towards renewable energy sources, the
imperative to minimise their environmental footprint across the full life cycle has become increasingly critical.
Here, we introduce a novel Hybrid process for recovering silver (Ag) from monocrystalline silicon (Si) PV cells
that achieves a 93 % Ag recovery yield. By selectively removing aluminium (Al) with sodium hydroxide (NaOH)
and delaminating busbars using iron chloride (FeCl₃), pure Ag is recovered by mechanical filtration, minimising
purification needs. Life Cycle Assessment (LCA) indicated reduced climate change and human toxicity burdens
compared to Conventional or Brine-based leaching, attributed to lower reagent consumption and fewer purification steps. Techno-economic analysis (TEA) highlighted cost challenges, indicating net losses due to high waste
disposal fees and chemical usage, despite substantial revenue from recovered Ag. These findings highlight the
critical role of high-value recycling and supportive policies in advancing a sustainable PV industry
The contingency effects of five sustainable development goals (big five SDGs): a cross-national study of socially responsible HRM and well-being
No full textThe emergence of the global sustainable development goals (SDGs) and the growing awareness of the economic, environmental, and social benefits of committing to sustainable development have led many organizations to consider how they can effectively contribute to this agenda. Drawing on institutional theory, this study seeks to advance this goal by examining in a multinational context how a socially responsible human resource management (SR- HRM) approach might support employees' well- being and whether a country's performance in achieving the five SDGs impacts this relationship. The results of multilevel analyses using data from 14,502 employees in 54 countries supported our hypotheses that SR- HRM positively influences both dimensions of employees' well- being (hedonic and eudaimonic). Furthermore, the moderating effects of national- level SDG achievement suggest that levels of SDG achievement strengthened the association between SR- HRM and employees' well- being. Our findings support institutional theory by showing that organizations and their HRM systems are shaped by their broader institutional environment. In order to modify HRM systems, the findings support an outside- in perspective in HRM and the role of formal instructions and regulations, such as the SDGs

Application of naphthalenediimide derivatives as self-assembled electron selective contacts in CdSe@ZnS Quantum Dots LEDs
Get PDFDespite the successful application of self-assembled molecules (SAMs) as hole-selective contacts in light-emitting diodes (LEDs), examples of the use of electron-selective SAMs are scarce. Here, we investigate the potential of naphthalene diimide (NDI) as an efficient electron-selective contact in CdSe@ZnS-based LEDs. CdSe@ZnS quantum dots, due to their exceptional optical properties, have found a range of applications in optoelectronics. In particular, they have been widely studied in LEDs because of their stability, tunable and narrow emission, and high photoluminescence quantum yields. In this work, two SAMs based on NDI cores have been synthesized, incorporating different terminal groups to study their structure-device function relationship. SAM3 contains one carboxylic acid moiety and one long alkyl chain as its substituents, whereas in SAM12, both substituents are carboxylic acids. Both inverted (n-i-p) and regular (p-i-n) device configurations have been explored and analyzed and our results show that the substituents play an important role in controlling device characteristics. Therefore, the application of NDI derivatives as electron selective contacts have been demonstrated opening the door for further research into the underexplored field of electron selective SAMs in optoelectronic devices
De novo expression of neuropeptide Y in sensory neurons does not contribute to peripheral neuropathic pain
Get PDFNerve damage induces a robust de novo expression of the pain-modulatory peptide neuropeptide Y (NPY) in large-diameter primary afferent neurons that innervate the dorsal horn of the spinal cord and the dorsal column nuclei. To determine whether this functions to modulate peripheral neuropathic pain in male and female mice, we selectively deleted the Npy gene in neurons of the dorsal root ganglion (DRG), without disruption of its expression in brain or dorsal horn neurons. We then subjected sensory neuron-specific NPY deletion mutant mice (Pirt-NPY) and their wild-type controls to either sham surgery, spared sural nerve injury (SNI) or spared tibial nerve injury (tSNI). Conditional Npy deletion did not change the severity or duration of static mechanical, dynamic mechanical, or cold allodynia in SNI or tSNI models, nor ongoing neuropathic pain as assessed with conditioned place preference to gabapentin. When injected after the resolution of tSNI-induced mechanical hypersensitivity (a latent pain sensitization model of chronic neuropathic pain), the NPY Y1 receptor-specific antagonist BIBO3304 equally reinstated mechanical hypersensitivity in Pirt-NPY mice and their wildtype controls. We conclude that nerve injury-induced upregulation of NPY in sensory neurons does not cause mechanical or cold hypersensitivity or ongoing pain, and that tonic inhibitory control of neuropathic pain by NPY in the spinal cord is mediated by release from dorsal horn interneurons rather than sensory neurons
A Coupled CFD-DSMC Approach To Analyse The Plume Surface Interaction In Rarefied Conditions
No full textWithin the ESA-funded activity, LUNAR In-Situ LANding Structures (LUNAR ISLANDS), the feasibility of in-situ manufactured structures is explored. These structures aim to decrease the exposure of surrounding infrastructure and personnel to high-velocity particles of lunar regolith, which result from the interaction of the exhaust plume of the lander and the surface, which is covered by loose regolith. Since replicating all lunar conditions in a terrestrial experimental setup is impractical, numerical simulations are crucial for analysing such flow scenarios. Therefore, the activity addresses both, experimental and numerical investigations. Data generated by cold-flow tests in vacuum condition and hot-gas tests in sea-level condition is used to validate the numerical model set up, which then allow for a more extensive study of the effects in an actual lunar landing scenario.
When modelling Plume Surface Interaction (PSI), it is essential to account for the limitations of solvers based on the Navier-Stokes equations, which may fail to capture key physical flow features in regions characterized by strong rarefaction and non-equilibrium effects. A hybrid modelling approach, combining a Navier-Stokes (NS)-based Computational Fluid Dynamics (CFD) solver with a Direct Simulation Monte Carlo (DSMC) solver, offers a robust framework for investigating PSI in these regimes.
This paper summarises the development and implementation of such a hybrid strategy within the OpenFAOM environment. The CFD solver is used to analyse the continuum region encompassing the nozzle and the plume of the engine, while the DSMC method is applied to capture the flow behaviour in the rarefied region. The identification of the continuum breakdown and the data transfer at the interface between the two solvers is handled automatically
The ORCID Advocacy Toolkit: towards a community-driven resource
Get PDFThis paper introduces the ORCID Advocacy Toolkit, a community-driven resource designed to support institutions in the successful adoption of ORCID iDs. Recognizing that effective advocacy requires both clear messaging and practical materials, the Advocacy Toolkit was developed through a collaborative, co-creation process involving librarians, research managers, and consortium members. Early stages focused on gathering existing advocacy content—such as templates, policy documents, and communication strategies—and identifying gaps in coverage. By hosting writing sprints and inviting broad participation, the project drew on diverse expertise to build a dynamic Wikibook suitable for institutions with varying needs and levels of ORCID experience. The establishment of an Editorial Board ensures ongoing updates, structured contributions, and alignment with emerging community requirements. In addition to highlighting common barriers to ORCID uptake—like low awareness or fragmented communication—the paper examines how flexible frameworks and peer-driven content can help overcome these challenges. Ultimately, the ORCID Advocacy Toolkit champions the principle of “from the community, for the community,” providing a sustainable, evolving resource that strengthens the open research ecosystem by supporting researcher recognition, knowledge sharing, and global collaboration
