Published: March 2024

Background: The present study aimed to determine the immune and stress responses of juvenile GIF tilapia fed with Ulva seaweed meal supplemented diet. Methods: The study was undertaken with different inclusion levels of Ulva seaweed meal (USM) such as raw (UR) and fermented (UF) Ulva meal (UR-5, UR-10, UR-15, UF-5, UF-10 and UF-15 % of diet) and control feed (C) for a period of 60 days. Result: GIF tilapia fed with fermented Ulva meal at a 10% inclusion level in their diet showed the highest growth (41.43 g). Immune parameters such as catalase activity (CAT), super oxide dismutase (SOD), respiratory burst activity (RBA), myeloperoxidase activity (MPA) and serum protein value (SPV) showed significant increases in fish fed with Ulva meal incorporated diet followed by UF-5, Ulva Raw (UR) 5%, control (C), UF-15, UR-10 and UR-15 diet respectively. Decreased glucose level was recorded in GIFT fed with fermented Ulva meal at 10% inclusion level followed by UF5, UR5, control diet, UF15, UR10 and UR15 diet. Increased plasma cholesterol, triglyceride, GPx activity, GRA activity and GST activity were recorded in GIFT tilapia fed with fermented Ulva meal at 10% inclusion level followed by UF5 diet, UR5 diet, control diet, UF15 diet, UR10 diet and UR15 diet. GIFT fed with fermented Ulva meal at a 10% inclusion level in their diet exhibited the highest growth performance (41.43 g) followed by UF5 (41.07±0.43 g), UR5 (39.65±0.36 g), control (39.09±0.20 g), UF15 (38.67±0.26 g), UR10 (38.47±1.47 g) and UR15 (35.77±0.35 g) diet. GIF tilapia fed with UF10 diet showed lowest FCR (1.34±0.00), highest SGR (0.99±0.00) and PER (2.37±0.07) followed by UF5 diet, UR5 diet, control diet, UF15 diet, UR10 diet and UR15 diet. One-way ANOVA data analysis and followed by Tukey’s test for conducting pair wise comparisons at significance level of 0.05. GIFT tilapia fingerlings had significant differences (P less than 0.05) among the different experimental diets. From the present experiment, it could be concluded that, Ulva meal incorporation at 10% in the diets increases immune responses in GIF tilapia.

Published: March 2024

Background: A significant impediment to the advancement of animal husbandry in India is the insufficient availability of green fodder throughout the year. The nutritive quality of forages is heavily influenced by farm-level management practices. Consequently, there is a pressing need to enhance productivity through the implementation of proper agronomic practices. The nutrient management in fodder-based cropping sequence is a key to maximize the fodder production and its quality. Methods: A field experiment was conducted using a randomized block design, consisting of twelve treatments incorporating various organic sources of nutrients. The experiment was replicated thrice during Kharif and Rabi season 2020-22 at Department of Forage Crops, Tamil Nadu Agricultural University, Coimbatore. The treatments included different proportions (100, 75, 50 and 25%) of the recommended dose of nitrogen applied through FYM, vermicompost and bio compost. Result: The experiment results of the three years study revealed that application of 50% RDN through FYM+ 50% RDN through vermicompost recorded the higher green fodder yield of 691 q/ha, dry matter yield of 130.7 q/ha and crude protein yield of 19.3 q/ha. Correlation and regression analysis also indicated that the growth and yield attributes had a positive impact on the fodder yield. Hence it can be recommended that application of FYM and vermicompost (50 and 50% RDN) found better source of organic nutrients for achieving sustainable and economical fodder yield with quality in fodder cowpea-maize cropping system.
Role of Glutamatergic Modulators in the Treatment of Obsessive Compulsive and Related Disorders
Authors: HELVACI ÇELİK Fatma Gül , HOCAOĞLU Çiçek
Published: March 2024

Due to the shared phenomenology and research findings related to disorders like obsessive-compulsive disorder (OCD), trichotillomania (TTM), body dysmorphic disorder (BDD), skin picking disorder (SPD), hoarding disorder (HD), and OCD, these conditions are collectively classified as Obsessive-Compulsive and Related Disorders (OCRDs) in the DSM-5. Despite having distinct features from OCD in terms of course and treatment outcomes, they are categorized together. The etiology of OCRDs remains incompletely understood, and information on their treatment is limited. Traditional pharmacological approaches often fall short in addressing the needs of many OCRD patients, necessitating alternative strategies. Recent research has shed light on a potential imbalance in glutamate, a crucial excitatory neurotransmitter in the brain, among certain patients with OCRDs. Findings from these studies suggest that glutamate modulators may be beneficial for individuals who do not respond to standard pharmacotherapeutic interventions. While no glutamate modulator has conclusively proven effective for OCD, promising results have been noted for memantine and riluzole. The evidence surrounding N-acetylcysteine (NAC) also positions it as a reasonable consideration for some patients. Noteworthy research on D-cycloserine (DCS) and ketamine has indicated potential benefits, and investigations into the off-label use of these pharmacological agents, originally approved for other indications, have been particularly focused on refractory OCRDs. It is essential to highlight that these drugs operate through diverse and, in some cases, opposing mechanisms. However, it is crucial to acknowledge that the existing studies on the use of these drugs in OCRDs are still insufficient. A more in-depth exploration of glutamate imbalance in the etiology of OCRDs is needed to better understand the role of glutamate modulators in treatment.

Cyberbullying is defined as intentional, repetitive, and harmful behaviors carried out using computers, cell phones, or other electronic devices. In recent years, there has been an increase in the rates of cyberbullying parallel to the rise in Internet usage. Particularly among adolescents, the prevalence of cyberbullying and cyber victimization are quite high. Adolescents who cyberbully or cyber victim face serious mental health problems. In this reason, efforts should be made to prevent adolescents from being exposed to these negative effects. It is crucial to identify the risk factors and protective factors related to cyberbullying, as they can guide preventive interventions. The review aims to provide a comprehensive perspective on the risk factors and protective factors influencing cyberbullying. Furthermore, information was provided regarding the definition, historical trend, prevalence, and consequences of cyberbullying. In this review, firstly, the definition of cyberbullying is provided, followed by a detailed discussion of its history, prevalence, risk factors, and protective factors. It is expected that the study, which comprehensively explains the factors related to cyberbullying, will contribute to the literature on cyberbullying and provide guidance to professionals working in this field."

The use of mindfulness-based interventions in many areas is increasing day by day. Having knowledge of the components of mindfulness is also important to know the mechanisms in which mindfulness-based interventions are effective. This study has aimed to examine potential attentional mechanisms of mindfulness. In this context, mindfulness has been defined and attention and attention models have been briefly discussed in the study. Then, the relationship between mindfulness and attention has been examined, and previous research findings examining mindfulness and attention are included. The studies on attention and mindfulness seem to have more inconsistent results when conducted with adults, whereas the studies in adolescents and children seem to have more consistent results revealing that mindfulness-based interventions improve the attentional skills of the youth. Knowing the relationship between mindfulness and attention will aid to maximize the efficacy of mindfulness-based interventions and it will be a crucial step in identifying the people that might benefit from mindfulness-based interventions
Relationship between Sensory Processing Sensitivity and Personality Traits
Authors: ÖZPEK Tayfun , KANDEMİR Fatma
Published: March 2024

Reactions to stimuli vary from person to person. The same stimulus has different effects depending on the perception of different people and the physical and mental states they are in. Considering this difference, situations can be seen in which a person perceives a specific stimulus or group of stimuli as negative and disturbing for themselves. In particular, people with high levels of sensory processing sensitivity feel the negative effects of stimuli more intensely both in terms of their internal processes (hunger, pain, sadness, stress, etc.) and the situation of the physical environment (loud noise, bright light, pungent odor, etc.) which they are in. On the other hand, the existence of situations where sensory processing sensitivity has a positive effect is also noticeable. In this context, the relationship between sensory processing sensitivity and personality traits is examined. The concept of personality is explained in different ways by many different theorists in the international literature. In order to avoid confusion that may arise in the definition and understanding of personality traits, in this review study, personality traits are examined on the basis of the Five Factor Personality Theory. Within the framework of the personality definition of the Five Factor Personality Theory, The relationship between five basic personality traits and sensory processing sensitivity is examined by also considering the subdimensions of each five personality traits.

What happens in a child’s earliest years lays the foundations for their lifelong wellbeing. Supporting young children and families during this time is therefore critical for individuals, families, communities, and societies more broadly to thrive and flourish. This report shares research findings from the Enabling Early Child Development in Ealing (ECDE) project. It explores the perspectives and experiences of parents/carers with children aged 5 and under, alongside insights from staff from key services on early child development, with the aim of enhancing support in Ealing borough, London. While Ealing is home to a range of formal and informal assets for families and children, there is room to improve, particularly in the wake of the Covid-19 pandemic which has had a negative impact on the proportion of children meeting key developmental milestones.
The Political System of Daegaya Based on Ancient Tombs and the Building Group of the Ancient Tombs of Bongwan-ri
Authors:   Central Institute of Cultural Heritage, Lee Dong-Hee
Published: March 2024

This study examined Daegaya’s political system and social structure, and the characteristics of the building group of the ancient tombs of Bongwan-ri, focusing on the golden age of Daegaya, from the late 5th century to the early 6th century. The political system of Daegaya was examined with emphasis on the regional confederation theory and the ancient state theory. From an archaeological point of view, the ancient state theory can fit Daegaya as the size of the tombs and prestigious items of local heads under Daegaya’s control show an organic relevance with the Goryeong group. However, with regard to the content of literatures, the Daegaya confederation theory cannot be ignored. In other words, it seems necessary to divide it into a number of indirectly controlled areas that had strong autonomy and retained the country’s name externally, and the strength of the alliance would have varied depending on the distance from Goryeong Gara. Unlike Silla and Baekje, Daegaya’s indirect control over its affiliated countries would not have been strong. Daegaya was on the path to becoming an ancient state at a later stage of social development than Baekje and Silla, and it would be appropriate to see it as an early state. The structural characteristics and prestigious goods of the ancient tombs of Bongwan-ri, Goryeong, belonging to the Daegaya’s royal capital are similar to or even superior to those of local heads in the Daegaya region. The ancient tombs of Bongwan-ri is located in the northern part of Daegaya’s capital, and judging from the location and excavated artifacts, it is identified as an influential group that played an important role in the defense of Daegaya’s capital.
Reconstructing the Function and Role of Okcheon Yiseong Fortress Using GIS
Authors:   Central Institute of Cultural Heritage, Kang Dong-Seok
Published: March 2024

It is estimated that Yiseong Fortress was renovated along with Samnyeon Fortress. Gulsan Fortress has been discussed as an important strategic point for Silla in the west region of the Sobaeksan Mountain during the battle of the Three Kingdoms. In particular, the article on the renovation of Gulsan Fortress in the Samguksagi is mentioned as an important historical event that can examine Silla's strategy for external expansion, provinces governance, and depense system in the surrounding area. Specifically, it is believed that Yiseong Fortress served as an administrative and military base for Silla as well as a military base. In this paper, the status of Yiseong Fortress was examined using the spatial analysis method of GIS. First, in relation to the characteristics of the administrative ruling place, Yiseong Fortress had accessibility and control in terms of topography and geography. Yiseong Fortress was located in a low hill, so it was relatively easy to access compared to the mountain fortresses of the highlands. This means that it is equipped with conditions to more efficiently control the surrounding human and economic resources. In addition, it was found that effective control of the local people and the agricultural production infrastructure was also possible through the analysis of the relationship between the provinces and settlements. Yiseong Fortress was the only one located in Okcheon and Boeun in a nodule where land and waterways intersect. As a result of a proximity analysis of the fortresses around Chupungryeong-ro, which Silla used as an diplomatic expansion route, it was confirmed that Yiseong Fortress was recently in close proximity. This is consistent with the historical fact that Silla pioneered the arterial road network, completing the local organizational system around the Hub Fortress, and reorganizing the government ruling system. In addition, Yiseong Fortress also had the advantage of using the waterway network that was operated upstream of the Geumgang River. In other words, Yiseong Fortress would have played a role in securing or supplying goods secured in Boeun or Cheongsan through waterways as the center of the amphibious transportation network. Yiseong Fortress was included in the fortress group in the Okcheon area, which was at the forefront of confrontation with Baekje. This can be assumed as a regional government-level system, and the spatial status of Yiseong Fortress was examined through network analysis. As a result of the analysis, Yiseong Fortress advantageous in securing power and influence in the network composed of fortresses, and occupied a position to exert a strong ripple effect using his power as well as his role as an intermediary. This spatial status of the Okcheon Yiseong Fortress is considered to have served as the background for the renovation of Gulsan Fortress during the period between Soji-maripgan.
A Study on the Earthen Fortress of Gayari, Haman: Focused on the Construction Techniques and Structures
Authors:   Central Institute of Cultural Heritage, Kim Hyun-Bong
Published: March 2024

The Earthen Fortress of Haman Gayari are the remains of Earthen Fortress representative of Aragaya along with the Malisan Ancient Tombs, which were recently designated as a UNESCO World Heritage sites. The sites are located in the hills of Gayari, which offers an excellent view of most of the Hamancheon Stream basin. Although references to the sites have been confirmed since the Joseon Dynasty, the archaeological investigation began in 2018 and continues until 2022. As a result of the investigation, Earthen Fortress, which was built using formworked earth techniques, was confirmed for the first time in the Gaya area, and the interior space of a Earthen Fortress, one building with an elevated floor, seven buildings with pit-dwelling, four pits, and the pillar hole groups, archaeologically proving it was a living space for the Aragaya ruling class. In particular, Earthen Fortress, which has a total circumference of about 2.4 kilometers, is the largest among the Earthen Fortress of Gaya culture, and is on par with the royal fortresss of the Three Kingdoms, such as Buso Fortress in Buyeo and Wolseong Fortress in Gyeongju. The construction technique of the Fortress shows a difference between the first wall and the repaired, and the expanded wall. The first wall was built using the formworked earth techniques and the construction method, which is different from the formworked earth techniques of Hanseong Baekje. The repaired and expanded wall, embankment techique was used and the defense power was reinforced by installing a wooden fence. The structure of the Earthen Fortress consists of inner fortress and outer fortress, and shows a unique pattern connecting the Gayari Embankment from the northeast of the outer fortress. Also in the south of inner fortressthere is a presumptive embankment sites, which is also observed in Japanese colonial era photographs and intellectual maps. And the structure of the wall changes with time, and it changes from earthen fortress to a wooden fortress. Wooden Fortress is again divided into the slope barrier stage and the top barrier stage, and in the latter case, there is a possibility that the wall was raised once more. The construction techniques and structures of this sites do not simply show Aragaya's civil engineering technology, but it is a clue to understanding exchanges with neighboring countries and an important evidence to gauge Aragaya's national power. And around the Gayari sites, there are many major sites of Aragaya, including Bongsan Fortress, West ridge of the Malisan Ancient Tombs, Seonwang Ancient Tombs, Deokjeon Ancient Tombs, Pildong Ancient Tombs, and Gayari Embankment sites, so it is highly likely that Gayari Earthen Fortress was the royal fortress of Aragaya.
A Study on the Formation and Development Process of the 3rd~6rd Century Settlements in the downstream of Dong-cheon, Gwangyang

Published: March 2024

This article is a study on the process of settlements formation and development during the 3rd ~ 6th centuries in the down Dong-cheon area among the Gwangyang area, which is a regional area in the eastern part of Jeonnam.This region has been continuously yielding archaeological findings through recent ongoing excavations, necessitating further research utilizing both existing and newly acquired data. The historic sites over the down stream of Dong-cheon, Gwangyang region have been studied are 7 points and 10 locations. This place can be classified broadly into their features such as dwelling, mound, fortress, and production. This area is also where many foreign artifacts are concentrated. This is understood as the nature of the natural and geographic environment and the transitional zone of this area. Therefore, the above contents were reviewed, and the formation and development process of the Dong-cheon Stream downstream region in Gwangyang was examined by dividing them into Ⅰ~Ⅲ. In the 1nd period, natives broaden their residence to flatland in the 3rd centries and their housing culture and relics started to flow in and features as the transitional zone in the Mid-4th centries. It seemed that having grown while serving as a stopover for foreign relations, that to overcome the geographical limitation causing slow development, which located in boarder area of Mahan(馬韓) and Gaya(加耶). In the 2nd period, after early 5th cenries, the amount of Sogaya(小加耶) type relics have been appeared to overwhelmed to other political systems. Also their form of habitations had changed into a squre shape. Through the importing Mahan or Wae type relics, it can be seen as means of bridge in marine route connecting Baekje(百濟)-Mahan(馬韓)-Gaya(加耶)-Wae(倭) during this term. The down stream group of Dong-cheon, formed relationship between Sogaya(小加耶) more closely. It can be estimated by producing their own products and constructing mounded tomb of regional head’s tomb from fhe late 5th centries to early 6th centries, that indigenous forces had been increased. The eastern part of Jeonnam was designated as Imnasahyun(任那四縣), and it is certain that down stream of Dong-cheon were central settlement in Moru(牟婁). In the 3nd period, passing the first half of the 6th century, with the construction of Baekje(百濟) tombs and Maro Mountain Fortress, the downstream of Dong-cheon was included in the direct ruling system of Baekje's local administration, and it still remained as the central settlement of the Gwangyang region.

Published: March 2024

This paper is a study on the production and review of Songje-Ri Tomb No.1, Naju(NSR), Knives with Decorated Restoration excavated from NAJU. The research process first summarizes the status of Knives excavation and observations using scientific analysis. Second, by comparing Knives produced in Three Kingdoms Periods, selection materials that were referenced in the production are presented. Third, the process and production of the restoration and design drawings. Fourth, the review of the completed Restoration and archaeological consideration were carried out in order. NSRT No.1 knives are similar to those found in King Muryeong Tomb, Gongju(GKM) and Songhak-Dong Tomb No. IC, Goseong(GSD), Kannon-Yama Tomb, Gunma, Japan(J-KA). In particular, referring to the form of GKM(King) knives, the defective parts of the manufactured relics could be restored. Restoration production was completed by first making and assembling parts. The main production techniques used include Die Forming, Scoring, Drawing, and Stamping. The completed restoration was re-compared with GKM(King) knives. As a result of the comparison, GKM(King) knives also raised the possibility that there was a ring in the sheath fixing part as well as the sheath handle part. A pair of rings of NSR·GKM(King) and J-KA Knives are thought to be the basis for judging these knives in the same style. Styles such as NSR and GKM(King) artifacts were judged to be objects that were popular for a very short period of time. Knives excavated from the two historic sites were produced in succession for a short period of time and evaluated as data that could consider political and economic support for craftsmen at the time.

Published: March 2024

İngiliz yazar George Orwell, kendi sosyo-kültürel gerçekliğinin etkisiyle kurguladığı romanlarında, bilginin egemen güçler tarafından nasıl ve hangi araçlarla üretilerek kullanıldığını işlemekte ve böylece bilgi-iktidar ilişkisini gözler önüne sermektedir. Özellikle, Hayvan Çiftliği ve Bin Dokuz Yüz Seksen Dört adlı romanları, yazarın, hem bilgi-iktidar düzleminde şekillenen kendi sosyo-kültürel birikiminin etkilerini taşımakta hem de bu birikimin daha açık bir şekilde analiz edilmesine olanak sunmaktadır. Bu çalışmada, Michel Foucault’nun bilgi-iktidar üzerine serdettiği görüşlerinden faydalanılarak Orwell’ın ilgili romanlarında iktidarlar tarafından bilginin nasıl üretildiği, hangi yöntemlerin bilgi üretimine ve dolaşımına katkı sağladığı bilgi sosyolojisi perspektifiyle betimsel olarak çözümlenmektedir. Analiz neticesinde, ilgili romanlar kapsamında, bilginin iktidarlar tarafından üretilerek topluma propaganda ile servis edildiği ve bunun; düşman algısı yaratarak korkuyla, gözetim ve denetimle disiplin altına alarak, bilgileri çarpıtma ve geçmişi değiştirme yöntemiyle bir meşrulaştırma gerçekleştirilerek yapıldığı bulgulanmaktadır.

Published: March 2024

Kemal Tahir’in romanları, toplumsal meselelere odaklanması yönüyle sosyal bilimler disiplinleri tarafından farklı yönleriyle ele alınmıştır, fakat Kemal Tahir’in romancılığının toplumsal meseleleri ele almada onu sosyal bilimcilerden hangi yönleriyle farklılaştırdığının üzerinde ayrıca durmak gerekmektedir. Bu çalışma, Kemal Tahir’in romanlarının her birinin, konu ettiği dönem ve ilişkiler bütünün ötesinde bir Kemal Tahir romanları evreni olarak niteleyebileceğimiz bütünlüğün temeli olarak bireyin (özelde ise Türk bireyinin) toplumsal inşası meselesini ele aldığına işaret etmeyi amaçlamaktadır. Bu çerçevede kitap olarak ilk yayımı aynı yıl içinde (1967) gerçekleştirilen Bozkırdaki Çekirdek ve Devlet Ana romanlarında, yaşanılan fiziki ve sosyal çevrenin baskısının Türk bireyinin şekillenişini, toplumsal hayata cevap ve çözüm üretme biçimini nasıl belirlediğine bakılmaktadır. Bozkırdaki Çekirdek’te köy enstitüleri ve aydın-halk ikiliği, Devlet Ana’da ise bir çözülüş dönemi içindeki Anadolu’da toplumsal örgütlenmeyi yeniden inşa etme etrafında konu ilerlerse de, farklı dönemlere ve meselelere odaklanan bu iki eserin, Kemal Tahir romanları evreninin nirengi noktasını oluşturacak şekilde örtüşen bir karaktere sahip oldukları vurgulanmaktadır.
Demineralized freeze-dried bone allograft with/without i-Platelet-rich fibrin in 3 wall intrabony defects
Authors: Mathew Rinnu , Bhatsange Anuradha
Published: March 2024

Demineralized freeze-dried bone allograft (DFDBA) contains bone morphogenetic proteins (BMPs), hence is osteoinductive. Autologous platelet concentrates exhibit a higher quantity of growth factors. Both these biomaterials aid in bone regeneration when placed in three-wall intrabony defects. However, their efficacy when used alone and in conjugation is not clear. Aim: To assess clinical and radiographic efficacy of injectable platelet-rich fibrin (i-PRF) with microsurgical access flap in the treatment of three-wall intrabony defects in chronic periodontitis patients. Methods: Thirty sites with three-wall intrabony defects were randomly assigned to control and test group by computer generated method. The test group obtained i-PRF mixed with DFDBA while the control group received only DFDBA. Clinical parameters such as site-specific Plaque index (PI), Radiographic intrabony defect depth (IBDD), modified- Sulcular bleeding index (mSBI), Clinical attachment level (CAL), and Probing pocket depth (PPD) were measured at baseline, three and six months. Results: Intragroup comparison within the control group and test group exhibited statistically highly significant variation of mean PI, mSBI, PPD, CAL, and IBDD score from baseline to 3 months and from 3-6 months (p<0.001). However, intergroup comparison demonstrated no statistically significant variation of mean IBDD at all 3 intervals (p>0.05). Conclusion: i-PRF combined with DFDBA enhanced the radiographic and clinical parameters as opposed to DFDBA alone. The role of i-PRF is promising in its capacity for easy obtainability and increased potential to aid in regeneration.

Published: March 2024

Aim: This study aimed to evaluate the millimeter distances and active tip diameters of different periodontal probes. Methods: Two types of periodontal probes were analyzed (North Carolina (15-UNC) and PCP-12). Two manufacturers were selected for each probe type. Digital images of the probes were obtained and the distances were measured using a software program. The diameter of the active tip was measured using a digital caliper. Both variables were measured by two trained and calibrated examiners. The data were analyzed using the Bland-Altman method and two-way ANOVA with Tukey’s post-hoc test. Statistical significance was set at p<0.05. Results: A comparison of measurements between the 15UNC and PCP-12 probes showed a significant difference in all millimeter markings. The 15-UNC probe showed differences between the 3 and 12 mm markings. The PCP-12 probe only showed differences between the marks at the 12 mm mark. The 15-UNC probe had a similar active tip diameter between the two manufacturers. The PCP-12 probe showed a significant difference between the two manufacturers. Both types of probes had similar active tip diameters when compared by the two manufacturers. Conclusion: There was no standardization in relation to millimeter marks and tip diameters of the two types of periodontal probes produced by the two different manufacturers. The probe types exhibited little variability.

Published: March 2024

Aim: To assess the opinion of the students on the impact of COVID-19 pandemic on theoretical knowledge and clinical practice in dentistry at the Piracicaba Dental School – FOP/UNICAMP. Methods: A questionnaire was applied using the Google Forms platform, containing 20 questions related to the impacts of the pandemic on knowledge, mental health, and clinical and laboratory practice of dentistry. The satisfaction of the students with teaching was also evaluated. A total of 120 questionnaires were analyzed using R software, through tables and graphs of absolute and relative frequencies distribution. Results: COVID-19 affected the lives of 99% students who participated in the study. Due to distance learning resulting from the COVID-19 pandemic, 50% of the students considered locking or dropping out of college. Operative dentistry was the curricular component most affected by distance and lack of clinical practice. Although most students agreed that the workload of practical disciplines was or would be replaced, 95% felt some kind of deficit in clinical and laboratory practice even with the replacement of the workload. In addition, 93.3% of the students were afraid of not becoming a qualified professional due to the deficiencies on theoretical knowledge and clinical practice caused by the pandemic. Conclusions: Students showed dissatisfaction with the deficiency of clinical and laboratory practice resulting from the pandemic in operative dentistry curricular component. They reported fear and insecurity with their future professional lives. The indication of remote classes for dentistry should only be carried out in emergencies because this is an essentially practical course that suffers losses in learning.
Contação de história

Published: March 2024

Este ensaio enfoca a contação de história tendo por base a tese de que ela se realiza no movimento vivo da unidade social entre quem narra, quem ouve e a história narrada. Refutando sua concepção mais frequente de fundo subjetivista e relativista, sustenta-se, com base em Lev Vigotski, o caráter essencialmente histórico-cultural da subjetividade e da imaginação e que apenas nessa dimensão se pode compreender sua pertinência cultural e pedagógica. A contação de história não é uma atividade simples, exigindo suporte conceitual e sensibilidade artística por parte de quem conta. Pedagogicamente, a experiência cultural da criança necessita ser ampliada, pluralizada ao máximo, e a contação de história representa uma possibilidade nesta direção.

This paper aims to offer the first detailed inter-comparison of the performance from the numerical weather prediction models Consortium for Small-scale Modeling (COSMO) and Icosahedral Nonhydrostatic General Circulation Model, Limited Area Mode (ICON-LAM), integrated for the Romanian territory at the horizontal resolution of 2.8 km. As the ICON numerical model is set to replace COSMO, a comparison is carried out between the operational configurations of the two models. First, two cases with severe weather (strong atmospheric instability, observed heavy precipitation, and strong wind) are analyzed: February 3-6, 2020 (heavy precipitation [snow] and very strong wind) and May 3-5, 2020 (heavy precipitation). This is followed by a statistical inter-comparison between the two models for the summer of 2020 (June, July, August). A statistical evaluation of the forecast quality from the two models is performed objectively, through statistical scores computed using surface observations from all available meteorological stations on the Romanian territory. Stratifications depending on station altitude and location are carried out, with emphasis on stations of particular interest, depending on the evolution of the synoptic situation. Following the statistical evaluation, results for the precipitation forecast do not show significant improvement in favor of either model. However, ICON-2.8 km mostly outperforms COSMO-2.8 km for surface parameters.

Accurate cloud quantification is essential in climate change research. In this work, we construct an automated computer vision framework by synergistically incorporating deep neural networks and finite sector clustering to achieve robust whole sky image-based cloud classification, adaptive segmentation, and recognition under intricate illumination dynamics. A bespoke YOLOv8 architecture attains over 95% categorical precision across four archetypal cloud varieties curated from extensive annual observations (2020) at a Tibetan highland station. Tailor-made segmentation strategies adapted to distinct cloud configurations, allied with illumination-invariant image enhancement algorithms, effectively eliminate solar interference and substantially boost quantitative performance even in illumination-adverse analysis scenarios. Compared with the traditional threshold analysis method, the cloud quantification accuracy calculated within the framework of this paper is significantly improved. Collectively, the methodological innovations provide an advanced solution to markedly escalate cloud quantification precision levels imperative for climate change research, while offering a paradigm for cloud analytics transferable to various meteorological stations.

COVID-19 vaccine hesitancy and its enablers would shape community uptake of non-covid vaccines such as oral cholera vaccine (OCV) in the post-COVID-19 era. This study assessed the impact of COVID-19 vaccine hesitancy and its drivers on OCV hesitancy in a cholera endemic region of the Democratic Republic of Congo. We conducted a community-based survey in Bukavu. The survey included characteristics, intention to take OCV and COVID-19, reasons for COVID-19 hesitancy, and thinking and feeling about COVID-19 vaccines. Poisson regression analyses were performed. Of the 1708 respondents, 84.66% and 77.57% were hesitant to OCV alone and to both OCV and COVID-19, respectively. Hesitancy to COVID-19 vaccines rose OCV hesitancy by 12% (crude Prevalence Ratio, [cPR]=1.12, 95%CI[1.03-1.21]). Independent predictors of OCV hesitancy were living in semi-urban area (adjusted Prevalence Ratio [aPR]=1.10, 95%CI[1.03-1.12]), religious refusal of vaccines (aPR=1.06, 95%CI[1.02-1.12]), concerns about vaccine safety (aPR=1.05, 95%CI[1.01-1.11]) and adverse effects (aPR=1.06, 95%CI[1.01-1.12]), as well as poor knowledge (aPR=1.07, 95%CI[1.01-1.14]). Conversely, the belief about COVID-19 vaccine effectiveness reduced OCV hesitancy (aPR=0.76, 95%CI[0.62-0.93]). COVID-19 vaccine hesitancy and its drivers exhibiting a significant domino effect on OCV uptake. Addressing vaccine hesitancy through community-based health literacy interventions would likely improve the introduction of novel non-COVID-19 vaccines in post-COVID-19 era.
Selective Recovery and Recycling of Lithium from Produced Water Bakken Oilfield in North Dakota
Authors: Almousa Mousa
Published: March 2024

During the last decade, the demand for lithium has been growing exponentially with its widespread uses in manufacturing, especially with the worldwide deployment of electric vehicles. Thus, lithium is considered integral to the U.S. economy, technological advancement, and the pursuit of sustainable and clean energy solutions. The produced water is known to be rich in several minerals and valuable elements, such as potassium and magnesium, and a trace amount of precious elements including lithium. However, the existence of metals in the produced water is one of the challenges to extract lithium, especially magnesium which is located in diagonal positions within the periodic table that exhibit similarities. The produced water was first purified, resulting in the complete removal of magnesium, and then lithium was precipitated by phosphate. The effects of operating conditions on the Li3PO4 precipitation behaviors were evaluated. The effect of different precipitating reagents was evaluated on the percentage of lithium extracted, Na3PO4 (TSP) was found to be a promising Li precipitating reagent. The highest percentage of lithium extracted was reached when the Li concentration of produced water was enriched and increased up to 350 mg/l, then Li removal was 53% at 7 grams of TSP and 200 rpm for 2 hours. The results indicated that temperature is a more important factor than stirring speed. The novelty of the current work is not only by the results obtained that may create additional financial benefits to oil-producing areas but on that the sustainable disposal of produced water may encourage the recycling and reuse practice, ultimately reducing the use of freshwater for hydraulic fracturing.
Review of Accurate Detection of Human Skin Tissue Temperature Based on Microwave Radiation Method
Authors: Wu Jingtao , Liu Jie
Published: March 2024

Microwave radiation diagnosis technology can detect thermal changes in skin tissue earlier than anatomical changes, but its detection accuracy is limited by non-target radiation interference in the measurement environment, additional measurement errors of system units, and energy scattering and transmission between skin tissues. This paper aims to address the scientific challenges of analyzing the forward and inversion modelling detection mechanism of layered accurate temperature measurement of human skin tissue based on multi-band. The study focuses on the construction of a pencil beam antenna optimization system, the optimization strategy of high-sensitivity correlated radiometer architecture, and the high-precision multi-band forward and inversion modelling detection algorithm. The key technologies include: (1) A new method of integrated modeling and multi-index optimization of antenna with high directivity and small aperture is proposed, and a priori knowledge-guided neural network of pencil beam distribution is constructed to realize the inversion model of antenna structural parameters; (2) The influence mechanism of high sensitivity correlated radiometer architecture error is analyzed, and a periodic phase shift error correction algorithm based on uniform polar circle is designed; (3) Combining deep learning theory and hyperparameter optimization framework, an iterative model is established, and the objective function modified by the penalty factor is defined to realize a new detection method combining forward and inversion. This paper presents a theoretical foundation for the industrialization of microwave radiation diagnostic technology.

The existence of low-cost and accurate tools that can equip the First Responders (FRs) to detect trapped victims and provide insights about their health condition in the aftermath of a disaster, is imperative. To address the problem of detecting trapped victims behind walls or debris, we have developed a tool that exploits an Ultra-Wide Band (UWB) radar sensor for data collection and Machine Learning (ML) algorithms for data analysis. To evaluate the efficacy of our approach, we collected data from nine humans, both in standing and lying down positions. Next, we applied various ML algorithms to the collected dataset for two discrete sub-tasks that are of interest from an FR’s perspective. The first task is the detection of the victim’s presence, where the algorithms attained more than 95% accuracy and F1-Score. The second task is the estimation of the distance between the radar sensor and the victim, where the tool showed an average error of less than 40 cm.

Indigenous peoples around the world are revitalizing their ancestral beliefs, practices, and languages, including traditional understandings of health and wellbeing. In the Aotearoa (New Zealand) context, a number of ground-breaking Māori health and wellbeing related models have emerged, each with their own unique applications and offerings. We sought in these qualitative studies to explore and identify some key sources of wellbeing for Māori individuals. Nine interviews were conducted with members of Māori communities to identify key themes of Māori wellbeing. A Reflexive Thematic Analysis was performed on these data, and then a further fifteen interviews were conducted to revise, refine, and reposition the previously generated themes. The Ngaruroro describes wellbeing as the embodied and active process of being in good relation with your 1) here tāngata (social and familial ties), 2) te taiao (the environment), and 3) taonga tuku iho (cultural treasures), while doing what you can to make lifestyle choices that are conducive to the health of your 4) tinana (body) and 5) wairua (spirit), while cultivating a balanced 6) ngākau (inner-system), fulfilling 7) matea (core needs), and exercising your 8) mana (authority). These themes illustrate and reiterate that Māori wellbeing is dynamic, interconnected, and holistic.

External hoof characteristics, balance, and conformation have been extensively studied in horses; however, mules remain understudied in these aspects. This study evaluated the size, shape, and symmetry of untrimmed and unshod forelimb hooves, compared the symmetry between forelimb hooves and stratified external forelimb hoof measurements based on the body condition score of mules raised in the foothill plains of northern Thailand. The forelimb hooves of 38 mules were photographed and 33 parameters, including angular and linear measurements, were analyzed. Despite the absence of shoeing and trimming, these mules exhibited optimal left-right forelimb hoof symmetry, with no significant (p < 0.05) differences in: outer wall length and inner wall length (OWL - IWL); sole length and sole width (SLS - SW); dorsal hoof wall length and heel length (DHWL - HL); and frog length and frog width (FL - FW). However, significant (p < 0.05) differences were observed within each body condition score group for forelimb hoof measurements for DHWL, IWL, heel separation (HS), heel bulb distance (HBD), SW, FW, and FL. These findings provide valuable insights into mule welfare and management, contributing to understanding of the interplay between overall health and hoof conformation in the study area.
