The purpose of this research was to evaluate the efficacy of utilizing the anterolateral flap from the thigh region for reconstructing the oro-mandibular defects when compared to other forms of flap reconstruction. A propensity score-matched analysis of patients with an oncologic head and neck defect who underwent microvascular reconstruction was performed. Two surgical groups, i.e., ALT (anterolateral thigh flap and bridging Plate) only and DFF (simultaneous soft tissue and vascularized bone flap), were created. Incidence and subsequent management strategies for postoperative plate exposure were evaluated along with complications, overall survival, and postoperative quality of life (QoL). Sixty-two patients were 1:1 propensity matched (31 per group). The DFF group had a significantly larger soft tissue and bone defect than the single-flap group. The 5-year probability of not having a plate exposure was 45.5 and 47.4% for the double-flaps and single-flap groups, respectively (p = 0.186). The ALT-only group had a significantly higher rate of wound infections (38.7% vs. 12.9%, p = 0.02). The incidence of flap loss, re-exploration, inpatient mortality, plate fracture, medical complications, and overall survival were not significantly different.

The Cult Deficit: Analysis and Speculation
Authors: Bacon Roger’s
Published: May 2022

Using a dataset derived from the long-running “Cults” podcast by Parcast, I find that the number of new cults began to increase in the 50s, peaked in the 70s-80s, and has been in steady decline in recent decades. I discuss various factors (historical, technological, cultural, pharmacological) that may have played a role in the rise and fall of cults since the 1950s and speculate on what the future may hold.
The Impact of Innovation Policy Mix on Innovation Capability of SMEs
Authors: Zhou Tian
Published: May 2022

Innovation has become an important engine for promoting rapid economic development to high-quality development in the 21st century. Small and medium-sized enterprises (SMEs) are the most important innovation subjects in China, but due to the risk characteristics and positive externalities of innovation, innovation cannot only rely on the spontaneous behavior of enterprises, but also needs the support of national innovation policies. Based on this, this paper takes the listed SMEs from 2015 to 2019 as a sample to study the impact of three types of innovation policies—supply-based innovation policies, demand-based innovation policies, and environmental-based innovation policies on the innovation activities of SMEs. Further, we will explore whether there is synergy between different types of policies from the perspective of policy tool combination. The study found that supply-based innovation policy and environmental-based innovation policy can significantly improve the innovation capability of enterprises, while demand-based innovation policy has no significant impact. In addition, supply-based policies and environmental-based policies are complementary, which can alleviate the inhibitory effect of corporate financing constraints on innovation. This conclusion still holds under different robustness tests. Finally, this paper finds that the single and combined effects of innovation policies show differences in enterprises with different characteristics. For enterprises in the eastern region, high-tech enterprises, and large-scale enterprises, the supply-based innovation policy has a stronger role in promoting innovation. For enterprises in the central and western regions and high-tech enterprises, the environmental innovation policy has a stronger incentive for innovation, and the policy synergies exist only in eastern enterprises, high-tech enterprises and small-scale enterprises.

Secret messages can be concealed in ordinary media like audio, video and images. This is called as Steganography. Steganography is used by cyber attackers to send malicious content that could harm victims. Digital steganography, or steganography in photographs, is exceedingly difficult to detect. The detection of steganography in images, has been investigated in thoroughly by a variety of parties. The use of steganographic techniques to send more malware to a compromised host in order to undertake different post-exploitation operations that affect the exploited system. Many steganalysis algorithms, on the other hand, are limited to working with a subset of all potential photos in the wild or have a high false positive rate. As a result, barring any suspected image becomes an arbitrary policy. Filtering questionable photos before they are received by the host machine is a more practical policy. In this paper, a Generative Adversarial Network based model is proposed that may be optimized to delete steganographic content while maintaining the original image's perceptual quality. For removing steganography from photos while keeping the maximum visual image quality, a model is built utilizing a combination of Generative Adversarial Network (GAN) and Image Processing. In the future, utilizing a generator to synthesize a picture will become more popular, and detection of steganography in images will become very difficult. In comparison to other models that have been addressed further, the proposed model is able to give a mean square error of 5.4204 between the generated image and the cover image, as well as better outcomes based on several metrics. As a result, a GAN-based steganography eradication method will aid in this endeavor.

Teachers in classrooms constantly face a variety of challenges. Poor communication skills, lack of vocabulary, poor grammar, and lack of motivation among students can hamper the teaching and learning process. To deal with these issues, teachers use a variety of methods and teaching materials. This study was conducted to evaluate how teachers can use TV talk shows in their classes to inspire the students. This research study was carried out to understand if talk shows are an effective tool which could be used in classroom lectures. The findings show that using TV talk shows can often excite classes into enthusiastic collaboration in real. Exposing students to visual images of TV talk-shows are more effective than readings alone. They cannot act as substitutes for instructors but can complement readings and lectures. If properly introduced and discussed, TV talk-shows can stimulate inquisitiveness, willingness to learn more and provide frameworks for analysis. However, the focus is on how teachers can make their sessions more interesting and productive by integrating this teaching tool.

Published: May 2022

The paper describes the socio-economic conditions and some strategies to restore the productivity of eight villages in Henval Watershed in the Tehri Garhwal Himalayas. The study reveals that the ratio of female to male population is more due to migration of males in search of livelihood to the other places. The average livestock varies from 4.43 to 5.40 per family and average land holding from 0.26 ha (Manjyar) to 1.52 ha (Jaul). Almost all the families in surveyed villages are engaged in farming and their average annual income per family per year is very low and varies from Rs 4000/- to Rs 6500/- per month. Fodder and fuel wood collection is done from the nearby forests, mainly by the women and children of the family and they spend 3 to 4 hours in these activities. Due to grazing of animals and collection of fodder and fuel wood, these activities cause environmental depletion It is suggested that afforestation of village forest /community land through Agroforestry models like silvipasture/ silvihorti system etc, can provide a key to the economic prosperity of the rural hills and would also be helpful in fulfilling the requirements of local inhabitants and ultimately balancing the whole ecology of the Garhwal Himalayas.

Authors: Isnaini Heri
Published: May 2022

The representation of female characters in the novel “Hujan Bulan Juni” by Sapardi Djoko Damono is based on the concept of "modern meisje" initiated by Kartini. This concept is an implication of the presentation of independent women who are in various ways able to become influential figures in society. The concept of "modern meisje" is represented through the character of Pingkan, the female character in the novel “Hujan Bulan Juni”. Pingkan is described as a mixed Manado-Javanese woman who has character as a "modern meisje" representation. This character can be seen in various signs seen in the portrayal of the character, both from physical depictions, characters, attitudes, and dialogue. This article aims to show the representation of Pingkan figures as "modern meisje" in accordance with Kartini's feminist concept. The method used in this study is a quantitataif descriptive method by placing the novel as research data. In addition, feminist studies become a theory that is used as a basis and reference in discussion. The results of the discussion showed that the figure of Pingkan is a figure who represents the concept of "modern meisje" in Kartini's view. This representation can be referenced in the concept of free women, independent, visionary, enthusiastic, and personal. This representation is conveyed by Kartini as part of the idealism of modern female figures in the view of feminism.

In order to evaluate the importance of short-rotation coppice (SRC) as habitat for ground beetles, a SRC with stands of different tree species (poplar, willow, rowan) in the municipality of Schapen (NW-Germany) was investigated during several years and different rotation-phases using pitfall traps. Regardless of the plantation-age, the cultivated tree species and the rotation-phase, the ground beetle fauna of the surveyed SRC was dominated by widespread and common generalists. Species of conservation concern (exclusively xerothermophilic species) were found only sporadically and had their main occurrence in the two years following the establishment of the plantation. During this phase, Harpalus griseus, a rare and threatened species in Lower Saxony, was detected in large numbers. After 8 and 9 years respectively, species numbers as well as the number of specimens on the entire SRC and within its different stands were considerably lower than in the early establishment phase. The partial harvest of the poplar and willow stands caused a significant change in ground beetle communities and a strong increase in the activity of openland species. However, openland generalists were the main beneficiaries, while pioneer species like Harpalus griseus occurred only sporadically. Woodland species were found only rarely even in the 9th year after establishment. We conclude that the conservational value of SRC as habitat for ground beetles is generally limited, decreases with increasing plantation-age and that a mosaic of different tree stands, rotation-phases and headlands is not sufficient to promote pioneer species of conservation concern. In order to provide permanently suitable conditions for these species, additional measures extending beyond the regular management of the plantations are required. These should aim at the creation of sun-exposed ruderal habitats with a patchy herb layer and high proportions of bare ground within accompanying structures of SRC like headlands or rides.

Activity Testing the Effect of Antagonist Plants in Suppressing the Development of Incidence of Root Rot Disease Ganoderma sp. aims to determine the effect of antagonist plants in suppressing the development of stem rot disease incidence of Ganoderma sp. in oil palm nurseries. The study used a randomized block design with 7 treatments, namely Ganoderma+ginger isolate, Ganoderma+turmeric isolate, Ganoderma+lemongrass isolate, Ganoderma+temulawak isolate, Ganoderma+garut isolate, Ganoderma isolate and control. Each treatment with 5 replications with 2 sample plants. The parameters observed were the development of disease incidence through symptoms, height and number of leaf midribs of oil palm seedlings. The data were analyzed using the SPSS program. The effect of the treatment was analyzed by using fingerprints. If there is a treatment that has a significant effect, further tests are carried out with Duncan's Multiple Distance Test (DMRT) with a level of : 0.05. Based on the test results, it was found that the incidence of Ganoderma stem rot disease was the fastest, highest and most developed in each observation, namely in the treatment using ginger and lemongrass antagonists. While the lowest incidence of disease was found in the treatment of arrowroot, turmeric and temulawak. These antagonist plants have exudate containing antibiotics that can inhibit the growth of the Ganoderma fungus. The development of oil palm seedling plant height is strongly influenced by the physical properties of the soil and the presence of Ganoderma pathogens. While the Ganoderma pathogen did not affect the development of the number of leaf midribs, but only caused changes in leaf color such as necrosis.

It is a polymer used in various diseases and in facial and body sequelae of congenital or acquired diseases, and for aesthetic purposes too. The PMMA manufacturer claims that the product has been improved, purified, and standardized (3rd generation) with rigid microspheres regularity that does not allow phagocytosis, consequently, reducing the inflammatory reaction. Objective: To prove this statement, the present study was conducted, whose objective was to analyze the physical characteristics of the PMMA particles distributed by the two Brazilian companies. Results: The two samples showed no statistical difference, being virtually the same. Conclusion: The surface homogeneity and particle size confirmed the hypothesis of product improvement, which will positively reflect on the clinical results of the product application, this fact can be proven by future studies.
Research of the major methods and clinical outcomes of irrigation in endodontics: a systematic review
Authors: Souza Raphael Alves de , Castro Fábio Pereira Linhares de , Pires Oscar José
Published: May 2022

Introduction: In the context of endodontic treatment, mainly endodontic irrigation, endodontic therapy promotes the removal of debris from the pulp tissue, seeking cleaning and asepsis against various microorganisms. Objective: Carried out a systematic review of the main methods and clinical outcomes of irrigation in endodontics, presenting information on the effectiveness and biocompatibility on the dentin surface. Methods: The present study followed by a systematic review (PRISMA). The search strategy was performed in the PubMed, Scielo, Cochrane Library, Web of Science and Scopus, and Google Scholar databases. Results and Conclusion: The success of endodontic treatment depends on eradicating microbes (if present) from the root canal system and preventing reinfection. In research comparing the effectiveness of EDTA 17% maleic acid to 7%, and observed a greater effectiveness of maleic acid in removing the smear layer from the apical third of single-adicular human teeth. When compared to maleic acid, 5% of 17% EDTA proved to be equally effective. Irrigation with 70% ethanol showed a significantly higher percentage of clean root canal walls and greater depth of clean dentinal tubules when compared to irrigation with 2.5% sodium hypochlorite and 17% EDTA-T. The volume of irrigants and agitation act to reduce the microhardness of dentin in the root canal. The smallest reduction in hardness was found in the EDTA + NaOCl association, which can be explained by the fact that one substance has the power to neutralize the other. An alternative EDTA (EDTA - T) to the conventional one was studied and showed good results to remove the smear layer and a good antimicrobial action, but showed a greater potential to generate inflammation than conventional 17% EDTA and 10% citric acid. Finally, one study showed that PUI with continuous irrigation and SAF were more effective than EndoVac and the conventional syringe in removing the drug Ca(OH)2 from a standardized artificial groove in the apical part of the root canal.
Investigation of the main clinical findings of maxillary sinus surgery with platelet-rich fibrin: a systematic review
Authors: Mello Álvaro Augusto de , Esteves Edmilson da Silva , Manzini Régis
Published: May 2022

Introduction: The maxillary sinus is the largest of the paranasal sinuses and its function is to contribute to phonation resonance, conditioning the air we breathe and aiding in the production of mucus in the nasal cavity. Around 25% of all maxillary sinuses, there is an accessory bone that is located in a lower portion than the main ostium. Aiming to increase the bone formation potential of these grafts, combinations have been proposed to obtain better regenerative conditions through volume preservation and induction of cell migration differentiation. Objective: Conducted a systematic review of the main clinical findings of maxillary sinus surgery using Platelet-rich fibrin. Methods: The present study followed a systematic review model (PRISMA). Experimental and clinical studies were selected, involving retrospective, prospective and randomized studies. The online databases consulted were PubMed, Scopus, Ovid, Periodicos.com, and Google Scholar. Results and Conclusion: A total of 59 articles were found involving the surgery of the maxillary sinuses using plasma rich in fibrin. A total of 34 articles were fully evaluated and 24 were included and discussed in this study. Studies have shown that PRF has the characteristic of polymerizing. The incorporation of circulating cytokines increases in the fibrin network, implying a longer life for these cytokines, as they will be released and used only in the remodeling of the initial scar matrix, which is long-term. PRF is based on protecting growth factors from proteolysis that can maintain their activity for a longer period and stimulate bone regeneration more efficiently. Another study indicated the use of fibrin membranes obtained from PRF to seal the perforations. In the presence of perforations larger than 10.0 mm, the surgery must be aborted and re-entry performed after 60 to 90 days. Furthermore, the combination of biomaterial and PRF significantly improved bone regeneration in the peri-implant area. Therefore, although the results do not seem to confirm that PRF is better than other biomaterials, it is suggested that its use can result in a decrease in the total healing time, around 104 days, and improve the handling of the graft material.
IMPROVING HOME SECURITY USING BLOCKCHAIN
Authors: Nada Ratkovic
Published: May 2022

The major problem with the use of smart home technology is that it often leads to various security issues. This mainly happens because the devices use open internet connections that may be vulnerable and subjected to multiple threats, hackers, and viruses. Some household IoT devices are forcefully introduced to the market, exposing the customers to significant risk factors. The websites and links do not have any copyright information or any privacy policies, due to which the hackers may immediately steal the confidential information of the user. For instance, the door locking password may be hacked by cyber criminals, and they may use it to attack the home when there is nobody in the home. This paper presents how to use block-chain to improve home security.

THE INTERNET’S ROLE IN UNDERMINING THE CREDIBILITY OF THE HEALTHCARE INDUSTRY
Authors: Neyara Radwan
Published: May 2022

The widespread popularity of the internet can be considered both advantageous and detrimental to society, as the age of technological advancement sparks innovative ways in which people receive information. On one hand, the availability of the internet has allowed people to research their own health concerns and symptoms, which enables them to seek treatment faster. On the other hand, this can turn into an obsessive habit by cyberchondriacs who relentlessly scour the internet over any trivial health concern. Furthermore, the widespread popularity of the internet is also responsible for a surge in spreading misinformation, namely about the COVID-19 pandemic, which has led to undermining the credibility of trusted healthcare officials and organizations.

This paper aims to not only explore the problems that arise with the widespread availability of information via the internet, but to also explore possible solutions that would benefit society on both an individualized and collective scale. The solutions presented in this paper seek to assist individuals in rendering professional therapy services for Cognitive Behavior Therapy, and to assist the collective population in maintaining responsible internet usage.
Template-Free Synthesis and Control Drug Release of Calcium Carbonate-Hydroxylapatite Composite
Authors: Yahaya Sulemana , Ibrahim Tarlutu , Ibrahim Abdul-Rauf
Published: May 2022

We employed Gas expanded liquids (GXLs) technology to synthesize calcium carbonate-hydroxylapatite composite (CaCO3-HAp) nanoparticles and investigated the effects of reaction parameters on the properties of the composites as well as the performance of the composites as drug delivery agent using ibuprofen as a model drug in simulated gastric fluid. Separately, calcium carbonate and hydroxylapatite have been used extensively in pharmaceutical and drug delivery systems (DDS). However, both CaCO3 and HAp have individual draw-backs and limitations in applications. The results showed that the composite had good thermal stability and better surface area and pore (volume and size) properties. Studies on the performance of the composites as a drug delivery agent using ibuprofen as a model drug in simulated gastric fluid revealed that the composite promoted the dissolution of ibuprofen outstandingly. Whereas the low pressure loaded composite showed quicker relief potential (92% release) in 30 minutes with control release over desirable time frame (3h, 20 min), the high pressure loaded composite also exhibited quicker relief potential (80% release) in 30 minutes but with control release over remarkable time frame (6h, 40 min). The implication is that if a patient is administered with ibuprofen loaded into the synthesized composite at low pressure (10.0 MPa), the patient will experience quicker relief (92% release of ibuprofen) in 30 min and which will be sustained for almost 3.5 hours. Similarly, the high pressure (17.0 MPa) loaded ibuprofen will also provide a patient with quicker relief (80% release of ibuprofen) however, the relief in this case will be sustained for longer period; about 6.5 hours. Therefore, the high pressure loaded composite had tremendous effect on the control release of ibuprofen and can be used as effective drug delivery system (DDS) for drugs with similar characteristics.

En este artículo se describe la trayectoria investigativa del grupo Seminario de Investigación en Didáctica de la Matemática (SIDM), con sede en la Universidad de Huelva (España). En particular, se describen los aspectos relevantes del proceso de investigación que comienza en los años 90 con foco en las concepciones del profesor de matemáticas y que culmina con el proceso de creación del conocimiento especializado del profesor de matemáticas (Mathematics Teacher’s Specialised Knowledge, MTSK) y la actual configuración de la Red Iberoamericana MTSK. La creación de este modelo, hito clave de dicha trayectoria, es fruto del trabajo colaborativo de investigadores de diferentes países, suponiendo la continuación de nuestra investigación sobre el profesor de matemáticas, en aras de contribuir a la mejora de su formación. De este modo, pretendemos desentrañar cómo los intereses de investigación iniciales fueron derivando y complementándose con otros nuevos, y cómo la red de colaboración con otros investigadores se fue ampliando hasta la conformación de la Red Iberoamericana MTSK.

The aim of this study was to determine Vickers microhardness (HV) in bulk fill resins at different depths. Test specimens were prepared with different bulk fill resins: Filtek Bulk-Fill (3M ESPE) [FBF], Surefill SDR flow (Dentsply) [SDR], Fill-UP (COLTENE) [FU] and Surefill (Dentsply) [SF]. Semi-cylindrical test specimens were prepared in a mold 6 mm in diameter and 4 mm thick (n=5). A 1000 mW/cm2 light curing unit was applied (Coltolux LED - Coltene) for 20 seconds. HV was determined with three indentations (Vickers Future Tech FM300, 300 g, 8 s) at four depths: 1, 2, 3 and 4 mm from the top surface to the interior. Data were recorded immediately (t0) and 24 hours later (t24). Results were analyzed with two-way ANOVA (p<0.05), and multiple comparisons were performed using Tukey’s test. Mean and SD of HV at t0 for each mm were: [FBF] t0: 49.23(4.65) / 48.32(3.36) / 44.38(2.06) / 40.59(2.58); [FBF] t24: 61.37(3.47) / 62.63(3.03) / 57.27(5.22) / 56.37(5.88); [SDR] t0: 27.81(3.13) / 28.07(2.4) / 27.24(2.94) / 25.71(3.0); [SDR] t24: 35.11(2.16) / 35.17(1.96) / 35.53(1.81) / 33.18(2.08); [FU] t0: 41.43(1.41) / 39.87(0.88) / 38.11(1.81) / 39.09(1.92); [FU] t24: 49.27(1.54) / 48.77(1.77) / 48.65(1.88) / 46.76(4.93); [SF] t0: 71.35(7.09) / 67.39(9.76) / 68.95(6.21) / 64.1(8.35); [SF] t24: 76.06(6.61) / 75.31(9.37) / 75.2(11.57) / 69.81(12.14). ANOVA showed significant effect of material, depth and recording time (p<0.05), and Tukey’s test showed that recording sites (depths) differed significantly, giving four homogeneous groups. Under the conditions of this study, it can be concluded that microhardness of bulk-fill resins can be affected by depth and post-curing time.

The aim of this study was to determine the difference between real age (RA) and dental age (DA) in boys and girls from the Autonomous City of Buenos Aires (C.A.B.A.) by analyzing digital panoramic radiographs from the database of the Imaging Department at the Buenos Aires University School of Dentistry, using the Demirjian Method (DM). The sample consisted of 508 panoramic radiographs of 6- to 14-year old Argentines (268 female and 240 male). The Demirjian method was used to estimate dental age from each panoramic radiograph, and the Wilcoxon test was applied to perform a comparative analysis with the real age recorded in the image database. Average RA was 9.36 years (SD 2.11), and average DA according to the Demirjian method was 10.45 years (SD 2.31). For females, RA was 9.25 (SD 2.12), and DA according to the DM was 10.40 years (SD 2.41). For males, RA was 9.46 (SD 2.10), and DA according to the DM was 10.50 years (SD 2.22). An inter-class correlation coefficient (ICC) calculated as a correlation measure between dental age and real age was ICC = 1.09%. The ICC was 1.04% for the males and 1.15% for females. Significant differences were found between DA and RA (p <0.01) in general and according to sex. Real age was found to be lower than dental age in the study population from Buenos Aires City.

The literature contains little information on several non-clinical factors such as the association between graduate residency programs and the application of minimally invasive dentistry, or on dentists’ clinical decision-making processes for replacing restorations for esthetic reasons. This study evaluated whether non-clinical subjective factors influence the treatment decisions made by Brazilian dentists regarding technical and esthetic matters. Dentists were invited to participate in a cross-sectional survey by answering an electronic questionnaire containing clinical cases, regarding what treatment they would select for: T1 - a molar tooth with significant crown destruction and spontaneous pain, and T2 - premolar teeth with extensive amalgam restorations and no carious lesion or associated complaint. The survey also included questions about subjective variants (sociodemographic and professional). Chi Square test and Fischer’s Exact test were used to analyze the answers to T1, and one-factor analysis of variance and post-hoc Tamhane were applied to T2. The significance level was set at 5% for all analyses. A total 302 professionals participated in the study. For T1, it was found that clinical decision-making was influenced by the Brazilian region of clinical practice (p=0.005). For T2, a significant association was found between increased loss of patient tooth tissues and whether the professional had completed a residency program in Operative Dentistry (p=0.035), worked in a private practice (p=0.033), or if most of his/her patients belonged to a high estimated socioeconomic level (household income above $4350) (p=0.002). In conclusion, the clinical decision-making of Brazilian dentists varies according to professional profile, mainly with relation to the replacement of restorations due to esthetic concerns.

Translation is a popular known job in today’s world and this has been explored by many studies in terms of strategies, knowledge and theoretical framework. In this study, the researcher aims to discover attitudes towards translation in respect to common difficulties and strategies used in translation. The study employed 29 students studying Business Translation at University of Economics Ho Chi Minh City. A questionnaire was designed based on the mixture of a five-point Likert scale and a yes-no question type. It uncovered that the majority of them confessed that they still have difficulties in using vocabulary including specialized terms and grammar. They also had an attitude that translation is interesting, and they need to read more in both English and Vietnamese for linguistic and stylish equivalence. Then, the majority of them found Google as a tool to help them solve translation strategies. Finally, the study also suggested some solutions and other solutions discussed in the related studies to tickling translation challenges.
