Published: January 2023

Data librarians are responsible for managing research data, who play an active role in improving the literacy and capacity of the research community and information professionals. Some Indonesian programmes have emerged, but their role and readiness have not been studied. The aspects of personnel readiness to support research data management (RDM) are further discussed in this research, as obligated on the National System for Science and Technology Act No. 11 of 2019. This study was conducted to investigate the readiness of librarians, academic communities, and information professionals in managing research data. A mixed method was used in this research. Firstly, a poll survey was digitally distributed in thematic seminar discussions on data management to librarians and scientists performing RDM tasks. Then, more detailed information about the role of librarians in managing research data was gathered from selected informants on FGD. The study found several points about the role of data librarians in improving data literacy and capacity through advocacy, workshops, seminars, training, and apprenticeship development. We then called for the involvement of all stakeholders, the scientific community, and information professionals to encourage them to continue working together in building a good data management ecosystem through innovative and collaborative programs. The results of this study could be a policy recommendation for the development of the status of library functions by the supervisory authority, the National Library of the Republic of Indonesia. The scientific community could use them to raise awareness and capacity for research data management from all institutions as data owners (scientific community) and data managers (data librarians).

The social inclusion-based library transformation program initiated by the director of The National Library of the Republic of Indonesia serves as the background of the study. Libraries that prioritize social inclusion provide resources to the community to help them maximize their potential for welfare. The crucial and strategic function of Micro, Small and Medium Enterprises (MSME) is one of the factors contributing to Indonesia's economic growth. MSMEs and social inclusion-based libraries have a close working relationship since the community can develop imagination, innovation, and creativity in establishing and developing their products by library services. Airlangga University Library is one of the libraries founded on social inclusion and has been mentoring MSMEs in Surabaya's northern and eastern regions since 2019. The purpose of this study was to determine the role of sources of information, facilities and infrastructure as well as programs created by the Airlangga University Library in increasing the productivity and income of MSME actors. This is qualitative research using Focus Group Discussion (FGD) data collection technique. Interviews with 6 (six) assisted MSME actors showed that the programs created by the Airlangga University Library inspired them to be more enthusiastic about developing their businesses. The study's findings indicate that the library's programs can be used as a source of information for advancing and developing MSME. The Airlangga University Library is expected to provide more sources of information that are relevant to needs, infrastructure to market products and organize other programs that provide knowledge for MSME actors in developing business.

Classic non-homeostatic structures involved in food intake regulation are reciprocally influenced by metabolic signals. Orexigenic peptides expressed in the olfactory bulb (OB) and hippocampus (HP) modulate olfactory processing and memory, respectively. Hypothalamic circuits also modulate feeding behavior by activating and releasing Agouti-related peptide (AgRP) in response to orexigenic signals. An adequate response to fasting requires the expression of p75 neurotrophin receptor (p75NTR) in AgRP neurons. The present study aimed to determine whether there is a role for p75NTR and AgRP in the OB and HP on the feeding behavior of fasted rats. A group of fasted rats (FG) was confronted with a decision-making paradigm in a T-maze containing a standard chow pellet (CP), and the same pellet coated with a phenolic-rich avocado paste extract (AVO) on either end; their OB and HP were then analyzed with histological and molecular tools. FG rats had briefer feeding latencies, as compared to control rats fed ad libitum (median latencies: 55.4 vs 191.7 min, p = 0.032). They also had reduced cell counts in both brain structures, as compared to satiated rats. AgRP mRNA was not expressed in the HP of either group, however, it was found in the OB. p75NTR mRNA was expressed in both brain structures of FG rats. These results suggest that contrasting metabolic states (fasted or satiated) motivate different feeding responses, which are influenced by p75NTR and AgRP mRNA expression in non-homeostatic food intake brain structures.

Published: January 2023

Background: A wound is a disorder of the continuity of the epithelial layer of the skin or mucosa and can result from physical or thermal damage. Proliferation and remodeling processes are important phases in incision wound healing. Celery is believed to have the potential to regulate the inflammatory phase and accelerate the process of proliferation and remodeling of wound tissue. This study aims to evaluate the potency of celery extract (Apium graveolens (Linn)) on incision wound healing in vivo.

Methods: This study was an in vivo experimental study. A total of 24 rats were used in this study and divided into 4 treatment groups (2 control and 2 treatment groups). Analysis of epithelial thickness ratio and epithelial length was performed using SPSS using univariate and bivariate.

Results: The control group had the lowest epithelial thickness ratio, followed by 50% extract, 75% extract, and finally, the gentamicin group. The length of newly formed epithelium in wounds treated with Apium graveolens (Linn) extract group 70% (mean 1.461 mm) was similar to that treated with gentamicin 0.1% (mean 1.457 mm) and much better than those treated without extract (0.869 mm).

Conclusion: Celery extract (Apium graveolens (Linn)) has the potential to accelerate the process of reepithelialization of incision wounds in vivo studies.
The Development of the Battle of the Sasu during the Second War of Go-Tang (661-662)
Authors:   The Bukak Historical Society, Yi Sang-hun
Published: January 2023

In July 660, Silla-Tang allied forces destroyed Baekje. In 661, the Tang launched an attack on Goguryeo. The battle between Goguryeo and Tang from 661 to 662 was called the Second Go-Tang War. The Second Go-Tang War ended with the Battle of the Sasu in 662. In this study, the military base of the Tang army was specifically determined, and based on this, the defense battle was reconstructed. It is believed that the Sasu is located in the west, not east of Pyongyang Castle. The Tang army formed four camps to surround Pyongyang Castle. Bang Hyo-tae's troops were stationed in the west of Pyongyang Castle, installing a barrier along the shooter. Yoo Baek-young's unit was stationed on the left side of Bang Hyo-tae's unit, and Im Ah-sang and Jo Gye-sook's unit were stationed on the right side. And So Jeong-Bang is believed to have been stationed in the area of Maeup-san. Goguryeo troops first attacked Im Ah-sang's troops with weak defense facilities. When Im Ah-sang's unit was defeated, Bang Hyo-tae's unit was isolated and annihilated. As a result, the Tang army's siege of Pyongyang could no longer be maintained. In addition, the cold and food shortages were further aggravated by heavy snow at the time. In the end, the party forces, which received the military supplies supported by Silla, were relieved of the siege of Pyongyang and stepped down.

Description of Sleep Quality of Students of the Nursing Department, Faculty of Sports and Health, Universitas Negeri Gorontalo at the Academic and Professional Stages
Authors: Djamaluddin Nurdiana
Published: January 2023

In the process of becoming a nurse, nursing students need to go through two stages of education, namely the undergraduate stage of nursing (academic) and the professional stage (profession). These two stages of education have different learning loads and responsibilities. At the academic stage students will be equipped with nursing knowledge to then apply it at the professional stage to actual patients. This often results in poor sleep quality in nursing students. This study aims to describe the sleep quality of students majoring in nursing at Gorontalo State University. This study used a descriptive survey method with a sample of 545 respondents who were obtained using a total sampling technique. The research instrument used the Pittsburgh Sleep Quality Index (PSQI) questionnaire to measure sleep quality. The results showed that there were 438 respondents (80.4%) who had poor sleep quality, and 107 respondents (19.6%) had good sleep quality. The conclusion of this study is that the majority of students majoring in Nursing at Gorontalo State University who are currently undergoing the lecture process have poor sleep quality.
Busco un problema de investigación ¡y no lo encuentro!

Published: January 2023

a primera investigación se parece a un rito de iniciación académica. Quienes pugnan por obtener un grado académico se someten a singulares “árbitros de la ciencia”. De ahí, métodos inflexibles y dogmas soporíferos son usualmente los innegociables baremos que han de medir el grado de “cientificidad” de los tempranos intentos de investigación. El escaso cultivo del hábito de la lectura, la rigidez metodológica y la pobreza de habilidades para investigar han generado el “horror académico” en que vivimos. Esta consternación se sostiene en el uso del plagio para obtener fraudulentamente rimbombantes grados académicos.La capacidad de asombro de los peregrinos de la “investigación científica” desfallece frente a los irracionales obstáculos propuestos por los “árbitros de la ciencia”. Así, los investigadores son interpelados por indagar más allá de las fronteras de “la pequeña aldea de los problemas estereotipados de investigación”. Esta aldea comprende ideas ampulosas, problemas reiterativos y un esquema rígido que reprime cualquier intención de creatividad y asombro. Innumerables mentes inquietas transitan por los foros académicos buscando un problema de investigación relevante y no lo encuentran. Emergen en este contexto “los árbitros de la ciencia”, quienes valoran como inconsistentes, frágiles, intrascendentes y hasta pueriles todas las propuestas más o menos audaces de investigación. El problema consiste en iniciar la travesía, formulando indeliberadamente el problema de investigación, pues se requiere un esfuerzo previo antes de incursionar en la arquitectura de las cuestiones científicas. Así, este trabajo reivindica la fase cero de la investigación que se relaciona con reflexiones y operaciones intelectuales previas para plantear un problema científico relevante, así como la humildad necesaria para realizar actividad científica.

Bagaimana Pandangan Islam Tentang Kesetaraan Gender (Perspektif Kemanusiaan)? Metodologi penelitian yang digunakan adalah pendekatan kualitatif, menggunakan studi pustaka melalui buku, jurnal dan makalah yang berkaitan dengan penelitian. Manusia pada dasarnya adalah pelayan, dan tidak ada perbedaan antara pria dan wanita yang melakukan banyak tindakan baik untuk mereka, terlepas dari jenis kelamin mereka. Ada potensi dan kemungkinan yang sama bagi keduanya untuk menjadi hamba Tuhan yang ideal. Selain menjadi hamba yang penurut dan taat yang takut kepada Allah, maksud dan tujuan keberadaan umat manusia di bumi adalah agar mereka menjadi khalifah di bumi. Laki-laki dan perempuan memiliki kewajiban yang berbeda sesuai dengan kodrat masing-masing dalam keyakinan Islam. Selama pria dan wanita mempertahankan fitrah ini, mereka memiliki kesempatan yang sama untuk memiliki kehidupan penuh dalam pendidikan, sosial-masyarakat, politik, seni, dll. Sejumlah hadits Nabi yang memuji perempuan menunjukkan bahwa Islam adalah agama yang mengedepankan martabat dan nilai perempuan. Menjadi manusia tidaklah mudah, tetapi akan bodoh untuk membiarkan tantangan-tantangan ini membahayakan kehormatan kita. Secara khusus, saat menghadapi fenomena menolak perbedaan manusia, yang mengunci masyarakat dalam stigma ketidaksetaraan gender. Pria dan wanita menyadari bahwa mereka berdua adalah manusia, sebagaimana mestinya.

Familiar objects benefit more from transsaccadic feature predictions
Authors: Goktepe Nedim , Schütz Alexander C.
Published: January 2023

The transsaccadic feature prediction mechanism associates peripheral and foveal information belonging to the same object to make predictions about how an object seen in the periphery would appear in the fovea or vice versa. It is unclear if such transsaccadic predictions require experience with the object such that only familiar objects benefit from this mechanism by virtue of having peripheral-foveal associations. In two experiments, we tested whether familiar objects have an advantage over novel objects in peripheral-foveal matching and transsaccadic change detection tasks. In both experiments, observers were unknowingly familiarized with a small set of stimuli by completing a sham orientation change detection task. In the first experiment, observers subsequently performed a peripheral-foveal matching task, where they needed to pick the foveal test object that matched a briefly presented peripheral target. In the second experiment, observers subsequently performed a transsaccadic object change detection task where a peripheral target was exchanged or not exchanged with another target after the saccade, either immediately or after a 300-ms blank period. We found an advantage of familiar objects over novel objects in both experiments. While foveal-peripheral associations explained the familiarity effect in the matching task of the first experiment, the second experiment provided evidence for the advantage of peripheral-foveal associations in transsaccadic object change detection. Introducing a postsaccadic blank improved change detection performance in general but more for familiar than for novel objects. We conclude that familiar objects benefit from additional object-specific predictions.

Published: January 2023

Media is known to play a huge role in influencing minds and shaping perspectives. Movies are a part of the same media and very often the society/population gains knowledge and awareness from the movies. The characters, their roles, and the events roll on the screen and stick deeply in the minds of the audience. The present paper focuses on an Indian Bollywood movie “Dear Zindagi” that was released in 2016 and it is known to have addressed a lot of societal stereotypes and is best known to have impacted a lot of minds in terms of bringing a positive outlook towards life. The mainstream media has described it as a feel-good movie (“Dear Zindagi Audience Reaction”). The movie involves a huge role of a psychologist and ample amount of psychotherapy sessions which, therefore, sheds light on psychotherapy and mental health. In this paper the movie is studied and analysed to look for the therapeutic influence on the audience and discusses the emphasis given on learning to trust, the importance of forgiveness and communication, emotional independence, conflict in relationships, etc. The study aims on highlighting the therapeutic and positive sides of the movie Dear Zindagi.
Position, Tenure And Responsibility Of The Notary In Carrying Out The Position Of Notary
Authors: IRIANTORO Agung
Published: January 2023

Notary, as authentic deed-makers, has a vital role in people's lives. It is because society needs someone whose information is reliable and trustworthy, whose signature and seal (stamp) can provide solid guarantees and evidence, an impartial expert and an adviser who has no defects, who shuts up and makes an agreement that can protect in the days to come. The position of the notary must provide legal certainty services in the form of doing authentic deeds and making land deeds; in their duties, two main functions, namely the first notary has legal certainty responsibility to the public for any ratification of legal bindings, and the second is that the notary has the authority granted by law as a state official to provide legal reinforcement for legal bindings, which in the end gives peace and a sense of security to the community. The notary's responsibility is determined by the nature of the violation, the legal consequences it causes, and the potential mandatory risks. Therefore, Notaries, in carrying out their positions, doing authentic deeds, and others, apparently made mistakes, so what is used beeps fout is a unique term addressed to errors made by professionals with particular positions, such as Notaries whose mistakes are made carrying out the job.
Registration Of The Buying And Sale Of Land Rights Post Implementation Of The Presidential Instruction Number 1 Of 2022 Concerning Optimization Of The Implementation Of The National Health Security Program
Authors: WESNA Putu Ayu Sriasih , WIJAYA Edward
Published: January 2023

Land sales and purchases must be completed prior to the PPAT that intended to give legal clarity and protection to the owner of a land parcel or other registered right so that he may readily establish his ownership of the relevant right and for the efficient administration of property. Fundamental guidelines that must be followed when purchasing and selling land are the transaction procedure and the certificate document's validity. The government released Presidential Instruction of the Republic of Indonesia (Inpres) Number 1 of 2022 on Optimum Implementation of the National Health Insurance Program (JKN). The Presidential Instruction regulates the requirements for managing a number of public services such as buying and selling land, making SIM, STNK, SKCK, Haji and Umrah which must be registered as BPJS Health participants. In the Inpres Number 1 of 2022, the government instructed 30 ministries/agencies to require JKN-KIS for various purposes to ensure that all people are protected by health insurance. Some of these policies seem to have no relationship or connection, but they are actually very closely correlated. The government wants to ensure that all levels of society have health insurance, especially the upper middle class who have not been registered with the JKN-KIS program. BPJS Health participant cards is one of the requirements for buying and selling land. The BPJS Health participant card is a requirement in the application for registration services for the transfer of land rights or ownership rights to flat units due to buying and selling.
Breaking Degeneracies in Formation Histories by Measuring Refractory Content in Gas Giants

Published: January 2023

Relating planet formation to atmospheric composition has been a long-standing goal of the planetary science community. So far, most modeling studies have focused on predicting the enrichment of heavy elements and the C/O ratio in giant planet atmospheres. Although this framework provides useful constraints on the potential formation locations of gas giant exoplanets, carbon and oxygen measurements alone are not enough to determine where a given gas giant planet originated. Here, we show that characterizing the abundances of refractory elements (e.g., silicon and iron) can break these degeneracies. Refractory elements are present in the solid phase throughout most of the disk, and their atmospheric abundances therefore reflect the solid-to-gas accretion ratio during formation. We introduce a new framework that parameterizes the atmospheric abundances of gas giant exoplanets in the form of three ratios: Si/H, O/Si, and C/Si. Si/H traces the solid-to-gas accretion ratio of a planet and is loosely equivalent to earlier notions of “metallicity.” For O/Si and C/Si, we present a global picture of their variation with distance and time based on what we know from the solar system meteorites and an updated understanding of the variations of thermal processing within protoplanetary disks. We show that ultrahot Jupiters are ideal targets for atmospheric characterization studies using this framework as we can measure the abundances of refractories, oxygen, and carbon in the gas phase. Finally, we propose that hot Jupiters with silicate clouds and low water abundances might have accreted their envelopes between the soot line and the water snow line.
Molecular Mapping of DR Tau’s Protoplanetary Disk, Envelope, Outflow, and Large-scale Spiral Arm
Authors: Huang Jane , Bergin Edwin A. , Bae Jaehan , Benisty Myriam , Andrews Sean M.
Published: January 2023

DR Tau has been noted for its unusually high variability in comparison with other T Tauri stars. Although it is one of the most extensively studied pre-main-sequence stars, observations with millimeter interferometry have so far been relatively limited. We present NOEMA images of 12CO, 13CO, C18O, SO, DCO+, and H2CO toward DR Tau at a resolution of ∼0.″5 (∼100 au). In addition to the protoplanetary disk, CO emission reveals an envelope, a faint asymmetric outflow, and a spiral arm with a clump. The ∼1200 au extent of the CO arm far exceeds that of the spiral arms previously detected in scattered light, which underlines the necessity of sensitive molecular imaging for contextualizing the disk environment. The kinematics and compact emission distribution of C18O, SO, DCO+, and H2CO indicate that they originate primarily from within the Keplerian circumstellar disk. The SO emission, though, also exhibits an asymmetry that may be due to interaction with infalling material or unresolved substructure. The complex environment of DR Tau is reminiscent of those of outbursting FUor sources and some EXor sources, suggesting that DR Tau’s extreme stellar activity could likewise be linked to disk instabilities promoted by large-scale infall.
A Study of Particle Transport in Young Pulsar Wind Nebulae
Authors: Zhu Bo-Tao , Lu Fang-Wu , Zhang Li
Published: January 2023

The broadband emission of numerous pulsar wind nebula (PWNe) in our Galaxy can be well described by synchrotron radiation and inverse Compton scattering from relativistic particles, specifically electrons and positrons. However, the particle transport mechanism is still under debate. We use here a time-dependent model to investigate the particle transport process of the young PWN, while the particle cooling processes are also analyzed. Following applications of the model to six young PWNe, our results show that (1) the particle cooling process is dominated by adiabatic loss in the low-energy band but by synchrotron loss in the high-energy band; (2) the advection dominates the particle transport process in the low-energy band, whereas the advection and diffusion codominate in the high-energy band, indicating that both advection and diffusion play an important role in particle transport; and (3) the diffusion coefficient is (2–360) × 1024 cm2 s−1 at the electron energy of 1 TeV, i.e., about 3 orders of magnitude smaller than the value considered to be the average in the Galaxy. We conclude that a slow-diffusion mechanism may explain the multiband observation of the sample of six young PWNe considered in this study.
Magnetic Energy Dissipation and γ-Ray Emission in Energetic Pulsars
Authors: Hakobyan Hayk , Philippov Alexander , Spitkovsky Anatoly
Published: January 2023

Some of the most energetic pulsars exhibit rotation-modulated γ-ray emission in the 0.1–100 GeV band. The luminosity of this emission is typically 0.1%–10% of the pulsar spin-down power (γ-ray efficiency), implying that a significant fraction of the available electromagnetic energy is dissipated in the magnetosphere and reradiated as high-energy photons. To investigate this phenomenon we model a pulsar magnetosphere using 3D particle-in-cell simulations with strong synchrotron cooling. We particularly focus on the dynamics of the equatorial current sheet where magnetic reconnection and energy dissipation take place. Our simulations demonstrate that a fraction of the spin-down power dissipated in the magnetospheric current sheet is controlled by the rate of magnetic reconnection at microphysical plasma scales and only depends on the pulsar inclination angle. We demonstrate that the maximum energy and the distribution function of accelerated pairs is controlled by the available magnetic energy per particle near the current sheet, the magnetization parameter. The shape and the extent of the plasma distribution is imprinted in the observed synchrotron emission, in particular, in the peak and the cutoff of the observed spectrum. We study how the strength of synchrotron cooling affects the observed variety of spectral shapes. Our conclusions naturally explain why pulsars with higher spin-down power have wider spectral shapes and, as a result, lower γ-ray efficiency.
GRB 080503: A Very Early Blue Kilonova and an Adjacent Nonthermal Radiation Component
Authors: Zhou Hao , Jin Zhi-Ping , Covino Stefano , Lei Lei , An Yu , Gong Hong-Yu , Fan Yi-Zhong , Wei Da-Ming
Published: January 2023

The temporal behavior of the very dim optical afterglow of GRB 080503 is at odds with the regular forward shock afterglow model and a sole kilonova component responsible for optical emission has been speculated in some literature. Here we analyze the optical afterglow data available in archive and construct time-resolved spectra. The significant detection by Keck I in G/R bands at t ∼ 3 days, which has not been reported before, as well as the simultaneous Gemini-North r-band measurement, are in favor of a power-law spectrum that is well consistent with the optical to X-ray spectrum measured at t ∼ 4.5 days. However, for t ≤ 2 days, the spectrum is thermal-like and a straightforward interpretation is a kilonova emission from a neutron star merger, making it, possibly, the first detection of a very early kilonova signal at t ∼ 0.05 day. A nonthermal nature of optical emission at late times (t ∼ 2 days), anyhow, cannot be ruled out because of the large uncertainty of the g-band data. We also propose to classify the neutron star merger induced optical transients, according to the temporal behaviors of the kilonova and the nonthermal afterglow emission, into four types. GRB 080503 would then represent the first observation of a subgroup of neutron star merger driven optical transients (i.e., type IV) consisting of an early blue kilonova and an adjacent nonthermal afterglow radiation.
Opportunistic Search for Continuous Gravitational Waves from Compact Objects in Long-period Binaries
Authors: Singh Avneet , Papa Maria Alessandra
Published: January 2023

Most all-sky searches for continuous gravitational waves assume the source to be isolated. In this paper, we allow for an unknown companion object in a long-period orbit and opportunistically use previous results from an all-sky search for isolated sources to constrain the continuous gravitational-wave amplitude over a large and unexplored range of binary orbital parameters without explicitly performing a dedicated search for binary systems. The resulting limits are significantly more constraining than any existing upper limits for unknown binary systems, albeit the latter apply to different orbital parameter ranges that are computationally much costlier to explore.

Published: January 2023

Insects are gaining interest as a sustainable and highly nutritious source of proteins and lipids for food and feed production sectors. Insect bio-refinery includes lipid extraction by pressing, dewatering, microbiological decontamination, and protein fractionation. The present study is experimenting the use of instant controlled pressure-drop (DIC), an emerging technology, for treating yellow mealworms and evaluating its combined effects on insect bio-refinery steps. A preliminary study allowed identifying the optimal hydraulic pressing conditions forTenebrio molitor larvae. Then, establishing an experimental design with DIC operative parameters of the saturated dry steam absolute pressure and treatment time ranging between (0.15 and 0.45 MPa) and (15 and 35 s), respectively, allowed identifying the DIC impact as a pretreatment on different larvae properties. It was possible to identify the optimal pressing parameters at 6 MPa, 60 °C, 2 cm of thickness, and 0.15 mm/s as initial piston speed. Moreover, DIC performed at 0.15 MPa for 25 seconds stood as an efficient killing method. Thanks to the changes in the membrane’s structure it provokes, DIC treatment modified larvae properties, ensured a partial expulsion of the matter (up to 0.47 g/g dry basis (db)), and resulted in larval expansion (up to 67%) which resulted in a decrease in the apparent density. As for the chemical properties, the larvae and larvae juice colours were found to become lighter as we increased the treatment conditions, which might be caused by the inactivation of oxidative enzymes. Moreover, severe DIC operative parameters decreased the pressing yields from 68 to 55%, possibly caused by protein aggregation and denaturation phenomena that prevent molecules from coming out by pressing. However, the water activity and moisture, lipid, and protein contents remained unaffected.
COVID-19 and the effect of central bank intervention on exchange rate volatility in developing countries: The case of Uganda
Authors: Katusiime Lorna
Published: January 2023

The COVID-19 crisis has not only manifested as a tragic public health crisis but also as an unprecedented economic disruption characterized by economic deterioration, the sharp increase in market volatility and the blinding uncertainty about the impact of the pandemic, especially in the context of developing countries. It is therefore not surprising that central banks seeking to maintain macroeconomic and financial stability, which are critical for sustained economic development, have maintained the practice of central bank intervention, especially in developing countries. This paper empirically examines the effect of central bank foreign exchange interventions on the level and volatility of the Uganda shilling / US dollar exchange rate (UGX/USD). Utilizing daily data spanning the period December 30, 2016, to 1 December 2021, we estimate a foreign exchange intervention model within a GARCH theoretical framework. Empirical results indicate that foreign exchange interventions have had mixed impact on the volatility of the exchange rate.

Human capital analytics transforms this information into significant understanding which reveals deeper insights. HR analytics is the utilization of systematic procedure to determine the HR issues. Starting from discovering best fit candidate until his retention, businesses are taking a stab at a lot of keen choices. The choice of selection in HR for the majority depends on trust and dislike in other verticals in the organisations. In the author's analytical view, human resource is an abundantly disregarded field by and large when contrasted with different business verticals, however the right fit candidates are required for each business unit for better outcomes. Be that as it may, after the recession time frame of later half of first decade of the 20th century, the majority of the associations perceived the need of evidence based human resource management. To come up with better decision making in the field of HR, evidence based HRM driven by information and data should rehearse with analysis, making choices, and critical thinking.

Over the last few years, the digital technologies have grown at a rapid pace and have become a part of the daily lives of billions of people across the world. The advancements in the field of telecommunications and the availability of devices with enhanced capabilities have a major role to play in this growth. Numerous studies have also addressed and explained about this emerging trend in the entertainment and media industry in many parts of the world. Over-the-top services, commonly known as OTT, are delivered directly through a stable internet connection. Consumers are spending more time on the internet than ever before. The internet has become an essential part of their lives, and so is the usage of OTT. There has been a shift in the habits of consumers, particularly young consumers, between the age group of 16-34 years. For OTT players to continue and succeed further, a combination of ad-based models and subscription-based models seem viable. Here the authors have tried to understand the major factors responsible for the adoption OTT services among Indian consumers.

Artificial Intelligence-Based English Vocabulary Test Research on Cognitive Web Services Platforms
Authors: Liao Li
Published: January 2023

Automated interaction between agents necessitates the ability of these agents to discover and select from a set of similar (or identical) services. As a result, trust is used to assess the quality of different cognitive web services. Therefore, this paper proposes artificial intelligence-based English vocabulary test research (AI-EVTR) to overcome the student's requirement. Further, pre-test behavior analysis has been introduced to enhance the apps. Before and after the test period, both groups took a pre-test behavior analysis and post-test log analysis “Vocabulary Test in English.” The experimental group used an app-assisted English vocabulary questionnaire to share their points; they were not extremely motivated in the app-assisted approach using machine learning. Statistical approaches comprising independent samples were used to analyze the acquired data. The experimental group greatly improved between the pre-test and post-test in spelling. Language learning on the website can be an option.

Authors: Bin Li
Published: January 2023

In the field of education, digital learning plays an important part. For each passing day, digital learning is displacing the traditional method of education. An accurate analysis of a student's qualities improves their academic performance. With the advancement of technology and big data, there are many applications for big data analytics, including education. Huge volumes of academic information are being generated, and discovering a technique to harness and analyze this information effectively is a challenging issue among many educational organizations. In this paper, educational clustering big data mining system (ECBDMS) has been proposed. The cognitive web service based learning analytic(CWS-LA) system is integrated to securely categorize and provide ease of access to the data. ECBDMS has been found to improve performance gains of 92.8%, prediction ratios of 88.6%, clustering error ratios of 2.3 percent, learning percentages of 94%, and forecasting accuracy of 97.1 percent when compared to other existing methods.

Published: January 2023

The database is the core of the information management system. When there is no modern management tool such as enterprise information management system, the status of enterprise resources and the direction of adjustment are unclear, and it is quite difficult to make adjustment arrangements. In order to improve the information mining ability of enterprise database in the future, this paper combines intelligent optimization technology under artificial intelligence technology with information mining technology, and compares its information mining ability with traditional technology. The research results show that after using the intelligent optimization algorithm, the maximum mining times can reach 60 times/min, while the maximum mining times of the traditional algorithm is 33 times/min. This shows that the mining speed of the intelligent optimization algorithm used in this paper is much higher than that of the traditional algorithm. And the mining speed of enterprises transformed through intelligent optimization is nearly 40% higher than that of traditional algorithms.
