Generation Z's Binge-Watching Lifestyle in Using Over-The-Top (OTT) Media Services in Indonesia
Authors: Prihantoro Edy ,   Gunadarma University, Indonesia
Published: July 2024

Indonesia is the country with the highest Over-The-Top (OTT) media consumption in Southeast Asia. The consumption of OTT media grows by 40% every year. The existence of OTT media has raised the binge-watching phenomenon. This research focuses on how Generation Z's binge-watching lifestyle uses OTT media. This research uses a qualitative methodology by conducting a Focus Group Discussion (FGD) with four to six informants from six regions in Indonesia who actively use OTT media. The theory used in this research is the Media Ecology Theory. Results show that Generation Z watches movies they like more than three hours daily. They determine the duration, frequency, and platforms they want to use. Generation Z's motivations for binge-watching are pleasure (as a medium of entertainment and relaxation), efficiency (easy to access), control (having low self-control), fandom (wanting to feel close to the player), and recommendations from others (not being left behind by others). Binge-watching positively impacts by providing a more open perception of experience, thoughts, and points of view. However, binge-watching has negative impacts, such as lack of sleep and increased imagination. OTT media is advised to provide hourly reminders to viewers to pause while binge-watching. Keywords: Binge-watching, Over-The-Top (OTT) media, generation Z, lifestyle, COVID-19 pandemic.

A striking swing of voters marked the 2020 Regional Elections in Karangasem Bali. The incumbent pair, Mas Sumatri and Suari, who were predicted by a survey of 53.9% to win against Dana-Dipa by 37.2% during the campaign, actually showed a crushing defeat of 43.4% and a Dana-Dipa victory of 56.6%, according to the official results from the Karangasem General Election Commission (KPU). This study examines the phenomenon of swing voters in the 2020 Regional Elections in Karangasem by raising the problem of capital factors as the cause of swing voters in the 2020 Regional Elections in Karangasem and the political communication of candidates in minimising voter swing in the 2020 Regional Elections in Karangasem. This research uses a qualitative approach through observation techniques, interviews, document studies, and literature studies in its data collection. The data were analysed using capital theory in social practice. The results of this study show that the determinant factor, namely capital, occurs in the dynamics of swing voters and political communication in the 2020 Regional Elections in Karangasem by candidates delivering their vision and mission as their political communication messages. This research contributes as a reference related to the phenomenon of swing voters and the political communication strategies of candidates who contest to minimise swing voters.

Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Panchenko Svitlana , Rizun Volodymyr ,   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine
Published: July 2024

Pilgrimage is a social communication institution that plays a vital role in forming and strengthening social ties and communication among people. This form of travel has deep roots in religious traditions and reflects the human need for spirituality and the search for meaning in life. Pilgrimage involves traveling with the specific purpose of visiting a holy place or shrine to seek spiritual refreshment, appeal to higher powers, and perform religious rites or penance. This creates favorable conditions for interaction among people who share common beliefs and values. As a social communication institution, pilgrimage contributes to the formation of group identity and community, as people engaged in pilgrimage feel part of a larger community that unites their faith and goals. They communicate, share experiences, meet new people, and interact with residents and other pilgrims, which promotes the exchange of ideas, views, and mutual understanding. Additionally, pilgrimage creates opportunities for the development of social and communication skills. By interacting with different people, pilgrims learn to show tolerance, mutual respect, empathy, and understanding of other cultures and traditions. They acquire the skills of effective communication, the ability to listen and understand others, as well as identify themselves as part of the community. Therefore, pilgrimage, as a social and communication institution, promotes interaction between people, the formation of communities, and the development of social and communication skills. It creates a unique opportunity for communication, exchange of experience and knowledge, as well as deepening of spiritual development and enrichment of the life experience of each pilgrim.

Published: July 2024

BACKGROUND: The main cause of residual neurological symptoms after surgical carpal tunnel decompression is long-term compressive neuropathy of the median nerve in the carpal tunnel in the preoperative period. As a result, irreversible morphological and neurophysiological changes gradually develop on the part of the compressed median nerve, which may not recover after its decompression.
AIM: To establish an algorithm for the use of transcutaneous electrical nerve stimulation (TENS) of various modalities in the treatment of patients with residual neurological symptoms after undergoing surgical carpal tunnel decompression.
MATERIALS AND METHODS: We observed 100 patients with residual positive symptoms after undergoing successful of surgical decompression of the carpal tunnel. The control group consisted of 20 patients (10 women and 10 men) and underwent a 2-month course of standard drug therapy. The main group (n=80), in addition to the standard drug therapy carried out in the control group, underwent a course of TENS, which began on the 2nd month of drug treatment. Depending on the form of TENS therapy, patients of the main group were divided into 4 subgroups: the TENS placebo subgroup (n=20) underwent a course of ineffective TENS. High-frequency TENS subgroup (n=20) completed a course of high-frequency low-amplitude TENS. Low-frequency TENS subgroup (n=20) completed a course of low-frequency high-amplitude TENS. The high-frequency TENS + low-frequency TENS subgroup underwent a simultaneous course of high-frequency TENS and low-frequency TENS (n=20). Positive sensory symptoms of numbness, tingling, burning and a feeling of electric charge were rated by the patients themselves over the past 24 hours on a 10-point scale.
RESULTS: When comparing the subgroups of effective TENS (high-frequency TENS, low-frequency TENS, high-frequency TENS + low-frequency TENS) with the subgroup of ineffective TENS (placebo), a significant decrease in positive sensory symptoms was revealed in the subgroups of high-frequency TENS, low-frequency TENS, high-frequency TENS and low-frequency TENS by 112%, 40% and 163% respectively. When comparing the effectiveness of high-frequency TENS and low-frequency TENS with each other, it was possible to establish that high-frequency TENS exceeds the efficiency of low-frequency TENS by almost 2 times. However, the combination of low-frequency TENS with high-frequency TENS enhances the therapeutic effect of the latter by 46%.
CONCLUSION: The use of high-frequency TENS is recommended in the treatment of patients with residual positive sensory symptoms. For strong positive sensory symptoms with the development of secondary affective reactions, it is recommended to combine high-frequency TENS and low-frequency TENS to enhance the effect.

One of the most popular materials used in industry is aluminum and its alloys. The aluminum manufacturing process is likely to undergo a welding process. Aluminum can be welded by gas or arc welding, but arc welding is more satisfactory. The welding process on aluminum alloys has the potential to present a situation similar to Age hardening. This research was conducted to dig deeper into the impact of welding on the second phase strengthening mechanism in several series of aluminum alloys using impact test equipment with the addition of a modified digital instrumentation device. Modifications were made to the GOTECH impact test equipment model Charpy impact test 0027 by changing the pendulum and adding a plate to the holder to conform to the ASTM E23-02a standard and adding digital instrumentation tools, including load cells, amplifiers, data acquisition, and power supply. The specimens used were aluminum 5052 and 6061 with variations of base metal and TIG welded V 60°. The results of the modified impact test equipment can display a graph of the impact energy absorption of each specimen. Comparison between the manual calculation of absorbed impact energy and digital calculation of 5052 base metal aluminum specimens has an average deviation of 11,716 J, 5052 welded specimens have an average deviation of 1.341 J, 6061 base metal specimens have an average deviation of 0.729 J, and 6061 welded specimens has a mean of 0.845 J.
Think beyond TB lymphadenitis - Kikuchi fujimoto lymphadenitis
Authors: Alavandar Aishwarya , Mathivanan Koushik Muthu Raja
Published: July 2024

Kikuchi-Fujimoto disease (KFD) is an extremely unusual lymphadenopathy that typically affects females between the ages of 20 and 40, but the aetiology is still unclear. A 28-year-old female presented with right-sided cervical lymph nodes, but there was no history of fever, anorexia, or loss of appetite. Ultrasonography of the patient's neck revealed bilateral cervical lymphadenopathy. Both the acid-fast bacilli smear and GeneXpert tests returned negative results. Histopathology revealed the presence of lymphocytes and histiocytes mixed with karyorrhectic debris. Immunohistochemistry markers support the diagnosis of Kikuchi-Fujimoto lymphadenitis. This case demonstrates that early recognition of KFD reduces unnecessary evaluations and treatments and patient suffering.

KFD is a self-limiting disease that requires a systematic approach for a diagnosis; once the diagnosis is made and confirmed by techniques such as immunohistochemistry, symptomatic treatment alone would suffice in the majority of cases. The commonest presentation is an acute or subacute febrile illness associated with cervical lymphadenopathy.

Published: July 2024

Periodontitis is a chronic inflammatory noncommunicable disease that affects all parts of the periodontium and causes irreversible damage. A biological sign of either pathogenic or normal processes is called a biomarker. Finding biomarkers is helpful for tracking the advancement of pathological conditions as well as for disease prevention, diagnosis, and prognosis. Effective treatment depends heavily on early disease identification. The disease process's severity and potential implications are lessened by early detection and treatment. Traditional clinical criteria are frequently inadequate in the field of periodontology to identify sites of active disease, track the effectiveness of therapy, or gauge the degree of vulnerability to future. Medical researchers are committed to identifying molecular illness biomarkers that indicate a concealed deadly threat prior to the disease becoming complicated in order to overcome this obstacle. Saliva is a vital physiological fluid that contains a complex mixture of chemicals. As a diagnostic tool, it is becoming more and more popular.

Published: July 2024

The treatment of impacted teeth is a multidisciplinary process requiring close collaboration between periodontics and orthodontics. Impaction can have several causes, including physical obstructions in the eruption pathway, arch length discrepancies, or dental deformity. The management of these cases lies in the diagnosis established after an appropriate clinical and radiological examination. The age, position, etiology, and amount of space in the dental arch of an unerupted tooth determine how it should be treated. In several cases, orthodontic creating space, removing physical obstructions, and exposing the patient surgically with or without traction are general guidelines for treatment. In addition, ensuring adequate access to the tooth and the possibility of attaching an orthodontic anchor, the periodontal plastic surgery procedures associated with surgical clearance must preserve the integrity of the periodontium of the impacted tooth, as well as that of adjacent teeth, and above all promote the long-term maintenance of their periodontal health.

Published: July 2024

One of the ways to improve specific characteristics of the power plant of a launch vehicle for ladeploying payload to the near-Earth space is to provide the possibility of operation of a fixed nozzle in the design mode over the whole active leg of the flight trajectory. The nozzle should be compact, lightweight, well-cooled. For detailed testing of the possibility of introducing a nozzle into the rocket engine chamber it is necessary to be able to quickly assess the true value of the thrust and the specific impulse the chamber with such a nozzle can achieve. This article presents the results of comparison of the thrust and specific impulse, obtained during calculations using engineering methods, numerical modeling for the atmospheric section and high-altitude sections of the trajectory. The results of the calculation are compared with the experimental values of the specific impulse obtained on the rocket engine test-bed under atmospheric operating conditions. These results can be effectively applied both to evaluate new and to improve existing nozzle designs of wide-range rocket engines.

Published: July 2024

East Kalimantan has a superior commodity: tiger shrimp (Penaeus monodon). Some of these commodities are marketed to several areas in Samarinda City and to areas outside Samarinda City, namely West Kutai Regency (Barong Tongkok Market). The distribution process uses a cold chain (cool box) system for 12 hours of travel. Long distribution times cause product quality to decrease. This study aims to assess tiger shrimp's quality and handling strategies using a cold chain system at PPI Selili Samarinda City. The quality level is determined using organoleptic testing at points 1 (PPI Selili) and 2 (Pasar Barong Tongkok). The formal safety assessment (FSA) method is used to identify risks in each handling activity, risk assessment associated with tiger shrimp deterioration, risk control, and recommendations to minimize quality degradation. Based on organoleptic tests, the quality of tiger shrimp is included in the category of safe for consumption. Product handling activities included unloading products from ships, moving them to terminals, washing, structuring, packaging in cool boxes, transportation by shipping services, shipping to Melak Pasar Barong Tongkok, unloading from shipping services, and product arrangement. The highest potential risk is handling shipments to Melak Pasar Barong Tongkok, which has 22 potential hazards. Risk mitigation can be applied through socialization and evaluation related to suitable fish handling methods (CPIB) and making operational schedules for cleaning in the product loading and unloading area before and after handling activities.

Costs and effects of public aid during the COVID-19 pandemic. EU programmes and Polish anti-crisis shields. Purpose: The aim of this paper is to prove the thesis that the intervention activities of the Polish government and the central bank during the COVID-19 pandemic were necessary to overcome the economic consequences of the COVID-19 crisis. Methodology: The main research method is the monograph and the research techniques include analysis of legal documents and statistical data on public finance. Findings: The interventionism of the EU, combined with the actions of state institutions and NBP, had a positive impact on GDP dynamics and the labour market. Its negative effect was an increase in public debt and the money supply in the banking system. The imbalance between effective demand and effective supply was an important, yet not sole, cause of the persistent inflation of 2021–2023.

The article is devoted to the practice of one of the public authorities — the enforcement body, which in its activities is faced with unfair behavior of business entities of law — so-called “professional recoverers” (collection agencies, credit, microcredit and microfinance organizations), in various forms abusing the right to appeal (petition) in the course of enforcement proceedings, and, despite the fact that their activities are subject to administrative supervision by the enforcement authority, trying to control the behavior of the latter, use in their own in the interests of the federal budget funds, to cover the costs they need, to distract from the regular positive work of the bailiff on the execution of acts of judicial and other bodies and officials. Based on multiple cases from practice, the author raises the problem of abuse of law by business entities, and makes proposals of an organizational and legal nature to solve the problems outlined.

The effect of stress in pregnant female Wistar rats on the behavior and lipid peroxidation (LP) in the neocortex, hippocampus and hypothalamus in the female F2 generation during the ovarian cycle was investigated. We subjected pregnant females to daily 1-hour immobilization stress from the 15th to the 19th days of pregnancy. Further, family groups were formed from prenatally stressed and control male and female rats of the F1 generation: group 1, the control female and male; group 2, the control female and the prenatally stressed male; group 3, the prenatally stressed female and the control male; group 4, the prenatally stressed female and male. The females of the F2 generation born from these couples were selected into four experimental groups in accordance with the family group. At the age of 3 months, behavior of rats was studied in the “open field” test in two stages of the ovarian cycle – estrus and diestrus. After 7–10 days, the rats were decapitated and the neocortex, hypothalamus and hippocampus were selected to determine the level of diene and triene conjugates, Schiff bases and the degree of lipid oxidation (Klein index). In F2 females with one prenatally stressed parent, there was no interstage difference in locomotorexploratory activity and anxiety. If both F1 parents were prenatally stressed, female F2 rats retained interstage differences similar to the control pattern, while their locomotor-exploratory activity and time spent in the center of an “open field” decreased in absolute values. In the neocortex of F2 females in groups with prenatally stressed mothers, the level of primary LP products decreased and the level of Schiff bases increased in the estrus stage. In the hippocampus of F2 females in the groups with prenatally stressed fathers, the level of Schiff bases decreased in the estrus stage, and the level of primary LP products increased in group 2 and decreased in group 4. In the hypothalamus of F2 females in the groups with prenatally stressed mothers, the level of Schiff bases increased in the estrus stage and decreased in the diestrus; in addition, in group 3, the level of primary LP products in the estrus stage increased. Thus, we demonstrated the influence of prenatal stress of both F1 mother and F1 father on the behavior and the level of LP in the neocortex, hippocampus and hypothalamus in female rats of the F2 generation in estrus and diestrus.

Analysis of the mechanisms underlying autism spectrum disorder (ASD) is an urgent task due to the everincreasing prevalence of this condition. The study of critical periods of neuroontogenesis is of interest, since the manifestation of ASD is often associated with prenatal disorders of the brain development. One of the currently promising hypotheses postulates a connection between the pathogenesis of ASD and the dysfunction of neurotransmitters and neurotrophins. In this study, we investigated the expression of key dopamine receptors (Drd1, Drd2), brain-derived neurotrophic factor (Bdnf), its receptors (Ntrkb2, Ngfr) and the transcription factor Creb1 that mediates BDNF action, as well as cerebral dopamine neurotrophic factor (Cdnf) during the critical periods of embryogenesis (e14 and e18) and postnatal development (p14, p28, p60) in the hippocampus and frontal cortex of BTBR mice with autism-like behavior compared to the neurotypical C57BL/6 J strain. In BTBR embryos, on the 14th day of prenatal development, an increase in the expression of the Ngfr gene encoding the p75NTR receptor, which may lead to the activation of apoptosis, was found in the hippocampus and frontal cortex. A decrease in the expression of Cdnf, Bdnf and its receptor Ntrkb2, as well as dopamine receptors (Drd1, Drd2) was detected in BTBR mice in the postnatal period of ontogenesis mainly in the frontal cortex, while in the hippocampus of mature mice (p60), only a decrease in the Drd2 mRNA level was revealed. The obtained results suggest that the decrease in the expression levels of CDNF, BDNF-TrkB and dopamine receptors in the frontal cortex in the postnatal period can lead to significant changes in both the morphology of neurons and dopamine neurotransmission in cortical brain structures. At the same time, the increase in p75NTR receptor gene expression observed on the 14th day of embryogenesis, crucial for hippocampus and frontal cortex development, may have direct relevance to the manifestation of early autism.

Analysis of hyperspectral images is of great interest in plant studies. Nowadays, this analysis is used more and more widely, so the development of hyperspectral image processing methods is an urgent task. This paper presents a hyperspectral image processing pipeline that includes: preprocessing, basic statistical analysis, visualization of a multichannel hyperspectral image, and solving classification and clustering problems using machine learning methods. The current version of the package implements the following methods: construction of a confidence interval of an arbitrary level for the difference of sample averages; verification of the similarity of intensity distributions of spectral lines for two sets of hyperspectral images on the basis of the Mann–Whitney U-criterion and Pearson’s criterion of agreement; visualization in two-dimensional space using dimensionality reduction methods PCA, ISOMAP and UMAP; classification using linear or ridge regression, random forest and catboost; clustering of samples using the EM-algorithm. The software pipeline is implemented in Python using the Pandas, NumPy, OpenCV, SciPy, Sklearn, Umap, CatBoost and Plotly libraries. The source code is available at: https://github.com/igor2704/Hyperspectral_images. The pipeline was applied to identify melanin pigment in the shell of barley grains based on hyperspectral data. Visualization based on PCA, UMAP and ISOMAP methods, as well as the use of clustering algorithms, showed that a linear separation of grain samples with and without pigmentation could be performed with high accuracy based on hyperspectral data. The analysis revealed statistically significant differences in the distribution of median intensities for samples of images of grains with and without pigmentation. Thus, it was demonstrated that hyperspectral images can be used to determine the presence or absence of melanin in barley grains with great accuracy. The flexible and convenient tool created in this work will significantly increase the efficiency of hyperspectral image analysis.
