Published: June 2023

Abstract: Cloud computing offers a flexible and convenient means of exchanging data, with several advantages for both society and individuals. With the widespread usage of cloud emails and frequent reports of large-scale email leakage occurrences, the security property known as forward secrecy has become desirable and necessary for both users and cloud email service providers to increase the security of cloud email systems. Typical techniques of attaining forward secrecy, such as Diffie-Hellman key exchange and forward-secure public-key encryption, have not been extensively authorized and used because they fail to meet the security and practicality requirements of email systems at the same time. We introduce a new cryptographic primitive called forward-secure puncturable identity-based encryption (fs-PIBE) in this paper to capture forward secrecy of encrypted cloud email systems without sacrificing practicability. It allows an email user to perform fine-grained decryption capacity revocation. In the standard model, we design a framework for encrypted cloud email systems and instantiate it with a concrete fs-PIBE structure that has constant ciphertext size and proved security. We enhance the proposed fs-PIBE scheme to provide end-to-end encryption and outsourced decryption, respectively, to improve the security and efficiency of the presented framework.

Methods Twelve advanced EFL freshmen college students participated in this triad peer review and revision process of their essay writing with eight digital tools while conducting surveys and reflective questionnaires. Results The findings show that the participants used the Google Docs and Microsoft Words the most as they make it possible to share and suggest ideas and opinions with ease, followed by Google Drawings and Grammarly. With Google Drawings, participants can take time to think before writing, plan for what they want to say, and they can organize their thoughts. In the case of Grammarly, they can discover out grammatical errors immediately and they can see the sections where they were wrong. In the first writing process, the results reveal that the participants used five types of peer reviews and revisions: content, grammar, mechanics, vocabulary, and organization. Among these types, peer reviews and revisions focused on grammar were the most frequently used, followed by mechanics and content. In the second writing process, the overall number of peer reviews and revisions were reduced and peer reviews and revisions on content were the most frequently used. Conclusions During the peer review and revision with the digital tools, the participants exchanged the constructive peer reviews in a collaborative way and revised the suggestions with digital tools. The results showed that the participants felt more confident in English essay writing with digital tools after the peer review process in their writings.

Published: June 2023

Objectives This study aimed to rethinking the meaning of child-centered and play-centered curriculum, which are continuously emphasized in the national kindergarten curriculum, focusing on keywords related to ‘child-centered’ and ‘play-centered’. Methods The national kindergarten curriculum and curriculum manual were collected to investigate the meaning of a children-centered and play-centered curriculum. Text mining analysis was conducted through four stages using R. In step 1, the data collection and analysis units were planned. In step 2, pre-data manipulation was performed for data analysis. In step 3, keyword analysis and co-occurrence network analysis were conducted. Finally, in step 4, the analysis results were visualized. Results First, I analyzed the meaning of ‘child-centered’ curriculum by focusing on prenominal expressions that describe child-centeredness, such as ‘experience,’ ‘interest,’ and ‘spontaneity,’ and found that the degree centrality was high for the words child, interest, and experience, and teachers which represent educational targets and curriculum operators. The betweenness centrality indicated a strong emphasis on children's experiences, and the closeness centrality revealed a strong emphasis on activities. Next, I analyzed the meaning of ‘play-centered’ curriculum by focusing on the word ‘play’, and found that the degree of centrality was strong for the words education and activity, the betweenness centrality was prominent for the word interest, and the closeness centrality was evident for the words teacher and teacher's play support in relation to play-centered curriculum and operation. Conclusions This study will contribute to the future revision of the national kindergarten curriculum by providing a conceptual overview for clarifying the terms child-centered and play-centered.

Authors: AL-Amri Saud , Hamid Suraya , (Corresponding Author) Nurul Fazmidar Mohd Noor , Gani Abdullah
Published: June 2023

With the rapid evolution of interactive technology, the popularity of mobile augmented reality (MAR) as a learning aid has continued to grow. However, several studies have revealed that research on the impact of AR in the educational domain is both insufficient and in an early phase. More studies are required to evaluate the effectiveness of utilizing MAR in this domain. The purpose of this study was to measure the effect of a mobile training course designed using MAR on trainees’ motivation. We reviewed the associated concepts, highlighted the importance and effectiveness of MAR and explained the benefits and challenges of employing MAR in the educational domain. This study drew on John Keller’s motivational model components and emphasized the significance of intrinsic motivation. We used a quantitative approach and designed a mobile training course that uses MAR to train government employees in Oman. A total of 32 employees were randomly divided into an experimental group and a control group. The experimental group used the designed application, and the control group took a training course online via computers. A motivational survey was conducted, and SPSS statistical software was used for data analysis. The results revealed that there was a significant difference in the mean motivation value for the experimental group: the trainees from the experimental group were more motivated than those from the control group. This study confirms that learners are motivated to participate in mobile training courses designed using MAR, which can contribute to the development of human resources in various domains.

Authors: Rexhepi Gazmore , Zeqiraj Valbona
Published: June 2023

The aim of this paper is to analyze the impact of public debt on economic growth and the possible existence of a non-linear relationship in eleven European Union (EU) new member states (NMS) for the period 2000–2019. If we compare this study with the studies of Reinhart and Rogoff (2010) and Kumar and Woo (2010), in this study, we will use more recent data that will enable us to perceive the relationship between public debt and economic growth in the new EU countries. The results of our study show that the debt turning point is roughly between 40.16 and 61.2 percent of GDP, dependent on which subgroup we have analyzed. This paper contributes to determining the point of public debt that would contribute to the economic growth of the new EU member states.
RNDR M3 4S (1) 0F UR AVATAR GRLS*
Authors: AMUSED
Published: June 2023

This thesis is aimed at investigating virtual embodiment and how it can affect a performer's experience of; and relationship to the physical body. With this auto ethnographic case study I hope to shed some light on the ways virtual reality technology enables critical experiences and what effects these experiences could have, through my own personal journey. The study was conducted in the setting of my home using a Pico 4 VR head mounted display and HTC vive full body tracking. The project used for the case study was an audiovisual pole dance performance that was performed on the platform Neos VR and streamed to Studio 44 in Stockholm. The research is rooted in the artistic field but draws knowledge from psychological and social research on VR as a cognitive and embodied technology. The research methods used to gather and analyse the research material were visual research, phenomenology and deep listening. The data collection consisted of visual and text based data. On the visual data I applied thematic analysis, coding and categorising of the text based data and analysing hyper reflections with a phenomenological approach. I found that the experience of virtual embodiment did change my relationship to my own body in a positive way by feeling more grounded and accepting. I was less anxious about performing and felt more confident in myself. Because of the entanglement of the study it was not possible to solely contribute the outcomes of the effect to virtual avatar embodiment in itself. It did however demonstrate how these VR technologies could be used to enable norm critical experiences by the use of norm critical design applied to avatars challenging beauty ideals and societal norms of performativity. My virtual embodiment and its effects on me can give a unique insight that would benefit developers and users active in these platforms as well as for personal introspection and self development. The study serves as a good base to build future research on and I intend to further elaborate on the extensive research data that was gathered.
Canola meal valorization via hydrolysis for amino acid generation
Authors: Wanasundara Janitha , Tanaka Takuji , Warnakulasuriya Sumudu
Published: June 2023

This study investigated an alternative approach to valorizing canola
proteins by hydrolyzing them to generate amino acids (AAs).
Pre-treatment of cold-pressed (CP) cake and desolventized-toasted (DT)
meal with ethanol (99%, v/v) followed by protein separation was studied
as process optimizations to maximize protein recovery with higher
purity. The optimum ethanol pre-treatment conditions to achieve a meal
containing less than 1% oil was reached at a meal-to-ethanol ratio of
1:4 (w:w) and 50°C for 30 min extraction. The protein recovery reached
the maximum at pH 12 and a meal-to-solvent ratio of 1:10 (w:v), yielding
73% and 33% recovery from ethanol pre-treated CP and DT meals,
respectively, in a single extraction. Untreated and ethanol pre-treated
meals were hydrolyzed with 6 M HCl (protein-to-acid ratio of 5 mg:2 mL)
for 24 h at 110°C. The ethanol pre-treatment improved AA recovery and
released 373 mg AA/g dry CP meal biomass (dbm) compared to 279 mg AA/g
untreated CP cake dbm. However, no improvement in AA recovery upon
ethanol pre-treatment of DT meal. H2SO4 was examined as an alternative
acid. More than 80% of the total AAs of CP proteins were released with
3 M H2SO4, while for DT meal proteins, a 5 M concentration was needed to
achieve the same. Commercial canola meals can be utilized for generating
free AAs; however, the meal processing history may affect the yield.
A universal indicator for assessing the ease of humans learning wildlife behavior.
Authors: Taklis Christos
Published: June 2023

Understanding wildlife behavior is crucial for effective conservation
and management. However, studying the behavior of diverse species
presents challenges due to their complexity and the availability of
data. To address this, we present a universal indicator for assessing
the ease of humans learning wildlife behavior. This indicator
incorporates species familiarity, behavioral complexity, and data
availability, providing a standardized framework for evaluating
learnability. Applying the indicator to a diverse range of species
reveals insights into research priorities and knowledge gaps. The
indicator enables researchers, educators, and policymakers to prioritize
efforts, enhance conservation strategies, and facilitate effective
wildlife management and education initiatives. Its application has the
potential to contribute to a more comprehensive understanding of
wildlife behavior on a global scale. While the indicator is a valuable
tool, its limitations necessitate ongoing data collection and
refinement. The universal indicator advances our understanding of
wildlife behavior and informs evidence-based conservation and management
strategies.

Published: June 2023

Interleukin-12 (IL-12) is known to exert anti-tumor immune effects by
promoting the activation and proliferation of T cells and NK cells
within the immune system. However, clinical trials have observed
systemic toxicity associated with the administration of IL-12. This has
shelved development plans for its use as a cancer therapeutic drug.
Therefore, it is critical that we perform a systematic evaluation of the
toxicity and safety of repeated IL-12 administration. In this study, we
conducted a comprehensive evaluation of the toxicity and safety of
repeated IL-12 administration in rhesus monkeys by assessing its effects
on the immune system, organ function, and vital signs. Our findings
provide accurate dosage selection and administration plans that minimize
the risk of adverse reactions in patients while ensuring therapeutic
efficacy.
Female genital Tuberculosis in infertile women: a practical paradigm for management based on reproductive outcome on retrospective analysis of various subfertility therapies following anti-tubercular therapy
Authors: Mondal Rana , Jaiswal Neha , Bhave Priya
Published: June 2023

Objectives To determine fertility outcomes after diagnosing genital
tuberculosis followed by anti-tubercular therapy (ATT) and response to
different subfertility treatment modalities. Hysteroscopy and
laparoscopy data were also analysed to determine whether or not starting
ATT early on in the course of tuberculosis treatment was more effective.
Study design Among the infertile women, presented in department
Reproductive Medicine in Bansal Hospital, Bhopal from Feb 2014 to June
2022, who underwent diagnostic hysteroscopy and laparoscopy, 1083 women
having positive finding(s) suggestive of tuberculosis were received
anti-tubercular therapy for at least six months. Retrospectively, we
analysed the pregnancy outcome of these women after receiving
anti-tubercular therapy followed by different subfertility treatments.
Results In vitro fertilization (IVF) was a primary modality of
treatment. 551(55.88%) women undergoing IVF with their oocytes resulted
in 348(63.15%) clinical pregnancies, 264(47.91%) ongoing pregnancies,
84(15.24%) first-trimester miscarriages, and live birth in 246(44.64%)
women. Clinical pregnancy rate, ongoing pregnancy rate, and live birth
rate all show a statistically significant (P = 0.039) improvement when
illness is diagnosed early through hystero-laparoscopy and treated with
ATT, followed by fertility therapy. Conclusions Diagnostic hysteroscopy
and laparoscopy may be performed to examine high-risk infertile
individuals by analysing the reproductive system, including tubal
factor. This helps choose a treatment strategy and forecast its success.
This study shows that if ATT initiated at early stage as suggested by
endoscopy findings IVF reproductive outcomes equivalent to the
background population. Late-stage ATT results are often quite dismal,
despite the fact that IVF and other adjuvant therapy may improve
fertility.
The Role of Board Financial Monitoring Strength and Donor Pressure in Nonprofit Auditors’ Assessment of Changes in Program Expense Allocations
Authors: Lauck John R. , Bhattacharjee Sudip
Published: June 2023

Nonprofits face inherent risks from both donor pressure to increase program spending and a high propensity for reporting errors. Simultaneously, in contrast to for-profit settings, limitations of nonprofit governance can raise auditors’ concerns about a board’s effectiveness as a control mechanism. We experimentally examine how a nonprofit board’s stronger and weaker monitoring strength influences auditors’ assessments of a client’s program expense allocations under conditions of higher and lower donor pressure to increase program spending. Auditors assess management’s expense allocations as more appropriate, and document fewer risk factors, only when board financial monitoring is strong and donor pressure is lower. Further, auditors rely on strong boards to reduce errors, but not intentional misstatements related to management’s allocation of functional expenses. These findings suggest that, in contrast to how auditors use for-profit governance, auditors may question the ability of even strong nonprofit boards to mitigate instances of intentional functional expense allocation misreporting.
The Effects of Transparency and Group Incentives on Managers’ Strategic Promotion Behavior
Authors: Hecht Gary , Maas Victor S. , van Rinsum Marcel
Published: June 2023

We investigate managers’ propensity to engage in strategic promotion behavior. Strategic promotion behavior occurs when managers pursue personal economic interests when contributing to employee promotion decisions, such that the probability that relatively lower performing employees are selected for a promotion is increased. We develop theory about how two important organizational characteristics—transparency about individual performance levels and the presence of group incentives—jointly affect managers’ tendency to strategically influence promotion decisions. Using a stylized lab experiment, we find that transparency about individual performance levels decreases strategic promotion behavior when group incentives are absent but not when group incentives are present. We discuss how our findings contribute to our understanding of management accounting and control systems.

Authors: Prihatini Esti , Wahyuningtyas Irma , Rahayu Istie Sekartining , Ismail Rohmat
Published: June 2023

Fast-growing wood is rarely used by the community because of its low quality. This study aimed to modify the sengon (Falcataria moluccana) and jabon (Anthocephalus cadamba) into magnetic wood so they have new functions. In this study, the modification process was performed by impregnating five-level concentrations of Fe3O4 nanoparticles dissolved in two different dispersants, namely water and a mixture of furfuryl alcohol and water. The impregnation process is initiated by a vacuum of -0.5 bar, followed by a pressure of 1 bar for 120 min. The addition of furfuryl alcohol to the impregnation solution significantly increased the physical properties of magnetic wood. The presence of Fe3O4 in wood is also proven by the Fe-O groups observed from the FTIR spectrum analysis. The magnetic field strength also increased as the concentration level of Fe3O4 increased. Based on the results of this research, the best treatment was obtained on magnetic wood of sengon and jabon with furfuryl alcohol and Fe3O4 nanoparticles concentration of 7.5%.

Synthesis and Characterization of Poly(hydroxy)urethane from Polyols for Beech (Fagus sylvatica) Wood Impregnation
Authors: Sitanggang Vera Junita , Wistara Nyoman Jaya , Gérardin Philippe
Published: June 2023

A non-isocyanate route of polyurethane synthesis based on polyol (xylitol, sorbitol, glycerol, and PG3), alkyl carbonate (DMC and DEC), and diamine (HMDA, EDA, and DETA) was conducted for wood impregnation through in-site polymerization. The structure and mass average molecular weight (Mw) of the polyurethanes were analyzed using FTIR, NMR, and SEC. According to the results, polyurethane synthesis by a two-pot method in water brought cyclic carbonate degradation. The distribution of Mw of the polyurethanes showed that the most satisfying polymer (4380 g/mol) was prepared without solvent. Polyurethanes synthesized in methanol have a higher Mw than that in distilled water. In the same solvent, the use of HMDA resulted in a polymer with higher Mw than that of EDA. One-step wood impregnation in a solvent gave unsatisfactory WPG (12.59–19.71%) and LC (50.36–62.80%). However, one-step impregnation without solvent gave a higher WPG (78.39–87.63%) and a lower LC (19.11–21.25%). It is not feasible to be applied industrially. The two-step impregnation gave WPG (14.89-30.73%) and LC (42.22–56.52%). Wood impregnation using methanol or ethanol as the solvent was more recommended than using an aqueous solution. However, the resistance against leaching needs improvement.

Published: June 2023

Mining production is one of the important components of the economic development of the Russian Federation. But in the process of mining, environmental damage is caused, which must be compensated by reclamation (restoration). However, to date, the reclamation rate is inferior to that of extraction. A special feature of the legal regime of subsoil use is the dual form of land allocation: subsoil use (the Law of the Russian Federation «On Subsoil») and land use (the Land Code of the Russian Federation). In this paper, the technologies of parallel reclamation of sections (quarries) are considered, the project of which should be contained in a set of documents for obtaining a license for the development of subsurface resources. Parallel reclamation without using the mined-out space of the quarry involves the use of overburden rocks as materials for the construction of large-scale linear infrastructure facilities of the district, etc. Parallel recultivation using the developed space of the quarry (section) involves filling it with either current overburden rocks or recultivant obtained based on the mineral processing products or technogenic raw materials. At the same time, it is required to ensure that at least one side of the quarry is placed in the limit position in the absence of any communications on it. A prerequisite for the implementation of this approach is mandatory long-term planning. The reclamation plan and its direction should be developed before the start of mining operations in accordance with the needs of the region, and then consistently implemented. The necessary legislative and regulatory framework is available in Russia, but it needs to be finalized, in particular, clarification of the concept of reclamation. In this case, it is interpreted as the return of land to a new economic turnover. Close cooperation and interaction of business with the federal and regional authorities, scientific and design organizations is required to restore the lands disturbed by mining production in accordance with the current laws and regulatory framework in order to develop and implement geotechnological solutions that ensure the return of these lands to a new economic turnover.

Objectives: In 2021, the effectiveness of the COVID-19 vaccine was analyzed among people living in the Honam region (Gwangju, Jeollanam-do, Jeollabuk-do, and Jeju) of the Republic of Korea. And we investigated changes in the dominant virus strain.Methods: This study used the data provided by the Korean Ministry of the Interior and Safety for individuals ≥12 years old in the Honam region, and the Integrated Disease and Health Management System of the Korea Centers for Disease Control and Prevention for COVID-19-vaccinated individuals as of December 31, 2021. Statistical analyzes were performed using IBM SPSS ver. 23.0. The occurrence of confirmed cases by vaccination status, the relative risk, and vaccine effectiveness by vaccine type were calculated.Results: In 2021, the COVID-19 vaccination rate in Honam was 88.6%. The overall vaccine effectiveness (after 2 and 3 doses) was 98.7% (p<0.001). and the breakthrough infection rate was 0.16%. From week 21 to week 27 of 2021 (June 27 to July 3), the genome sequencing results were mostly alpha variants. The Delta variant emerged as the dominant variant after 27 weeks and the Omicron variant was found at 50 weeks (December 5–11).Conclusion: Vaccine effectiveness changed with the outbreak of new variants of the virus as well as over time as antibody levels decreased. that the prevention effectiveness of vaccination in Honam was >98%, and the effect among persons who received 2 doses was >90% regardless of the vaccine type. Although vaccine effectiveness decreased because of reduced antibody levels over time (as observed in breakthrough infections), receiving a booster dose restored the neutralizing antibody levels.

Closed oak forests occur at the Tengelic Sand Ridge as isolated fragments, growing primarily in interdunal depressions and on dune sides. They occupy habitats a little above the otherwise similar oak hornbeam forests (Convallario-Carpinetum). Their structure, species composition and phytogeographical characteristics strongly resemble those of the closed pedunculate oak forests found in the sand ridges between the Danube and Tisza Rivers and at the western flanks of the Bakony Hills (Polygonato latifolii-Querectum roboris Borhidi in Borhidi et Kevey 1996). According to the results of traditional and multivariate statistical analyses, these oak forests are identified with the latter association.

Published: June 2023

OBJECTIVE

To report to what degree narrative operative reports for soft tissue sarcoma (STS) and mast cell tumor (MCT) resections met a predetermined template made up of essential elements.

ANIMALS

197 consecutive client-owned animals between May 1, 2017, and August 1, 2022.

PROCEDURES

A consensus list of 9 elements made up the final synoptic operative report (SR) template. Consecutive narrative surgery reports (NRs) of dogs that underwent MCT or STS resection were then reviewed to determine how many of the SR elements were present in each NR. A score was then determined for each NR out of a maximum total of 9.

RESULTS

Overall, 197 reports (99 MCT and 98 STS) were included. The median score was 5 (56% of elements reported). No report had all 9 elements, and 1 report had none of the elements reported. When MCT and STS were analyzed independently, the median score was 6 (67% of elements reported) for MCT and 5 (56% of elements reported) for STS. There was a trend of more cases with MCT that had a preoperative diagnosis, intraoperative measurements of the tumor, and surgeon margins marked compared to dogs with STS. More dogs with STS had an estimated Enneking dose compared to dogs with MCT.

CLINICAL RELEVANCE

Our data show that essential elements of STS and MCT resection in dogs were inconsistently recorded and no case had all elements present. This mirrors data in people and presses the need for more standardization in reporting of cancer operations in veterinary medicine.

Realismo enfermizo mexicano. Reygadas y Escalante
Authors:   Universidade da Madeira (Portugal), Galbis Pau Pascual
Published: June 2023

A hyper-realistic journey into the abyss of contemporary Mexican society, which Luis Buñuel would inaugurate with the premiere of The Forgotten in 1950, where poverty, evil and a disturbance, very naturalistic strangeness intermingled. In this paper, a selection of uncomfortable and transgressive films by Amat Escalante and Carlos Reygadas will be analyzed, in which pathological realism predominates, through narratives close to the bitter and implausible. Feature films that exhibit repressed desires, violence, impunity, and corruption. Blemishes and obsessions that current Mexico unfortunately suffers, in which both authors express themselves in a portentous and critical way towards these plagues. Finally, productions that evoke a poetic and incisive look at the various problems of the North American country.

OBJECTIVE: To describe the knee- and overall health-related quality of life (QOL) 3 to 12 years after anterior cruciate ligament (ACL) tear, and to assess the association of clinical and structural features with QOL after ACL tear.

DESIGN: Cross-sectional analysis of combined data from Australian (n = 76, 5.4 years postinjury) and Canadian (n = 50, 6.6 years postinjury) prospective cohort studies.

METHODS: We conducted a secondary analysis of patient-reported outcomes and index knee magnetic resonance imaging (MRI) acquired in 126 patients (median 5.5 [range: 4–12] years postinjury), all treated with ACL reconstruction. Outcomes included knee (ACL Quality of Life questionnaire [ACL-QOL]) and overall health-related QOL (EQ-5D-3L). Explanatory variables were self-reported knee pain (Knee Injury and Osteoarthritis Outcome Score [KOOS-Pain subscale]) and function (KOOS-Sport subscale), and any knee cartilage lesion (MRI Osteoarthritis Knee Score). Generalized linear models were adjusted for clustering between sites. Covariates were age, sex, time since injury, injury type, subsequent knee injuries, and body mass index.

RESULTS: The median [range] ACL-QOL score was 82 [24–100] and EQ-5D-3L was 1.0 [−0.2 to 1.0]. For every 10-point higher KOOS-Sport score, the ACL-QOL score increased by 3.7 points (95% confidence interval [CI]: 1.7, 5.7), whereas there was no evidence of an association with the EQ-5D-3L (0.00 points, 95% CI: −0.02, 0.02). There were no significant association between KOOS-Pain and ACL-QOL (4.9 points, 95% CI: −0.1, 9.9) or EQ-5D-3L (0.05 points, 95% CI: −0.01, 0.11), respectively. Cartilage lesions were not associated with ACL-QOL (−1.2, 95% CI: −5.1, 2.7) or EQ-5D-3L (0.01, 95% CI: −0.01, 0.04).

CONCLUSION: Self-reported function was more relevant for knee-related QOL than knee pain or cartilage lesions after ACL tear. Self-reported function, pain, and knee structural changes were not associated with overall health-related QOL. J Orthop Sports Phys Ther 2023;53(7):402–413.
