Tiers-lieux et développement territorial : des initiatives locales à la co-construction d’une politique nationale
Authors: Liefooghe Christine
Published: December 2023

Concept proposé par Oldenburg (1989), le tiers-lieu est un espace de sociabilité publique hors des cadres familiaux et professionnels. À l’ère d’Internet, sont nommés tiers-lieux des espaces de travail collaboratif ( coworking , makerspaces …) initiés par des collectifs locaux d’usagers. Structures émergentes au modèle économique fragile, ces lieux d’innovation économique et/ou sociale ancrés dans leur territoire sont des leviers de développement local. L’article explore l’émergence de politiques – locales, régionales et nationales – en faveur des tiers-lieux. L’analyse multi-scalaire de ces politiques et des réseaux d’acteurs plaide pour une circulation interterritoriale de la notion de tiers-lieu, dont la définition varie selon le type de politique et l’échelle d’action. Alors que s’opposent les valeurs et pratiques des tiers-lieux (ouverture, liberté) et de l’action publique (procédures, contrôle), un cadre de référence socio-technique commun à ces deux mondes émerge de la co-construction d’une politique nationale innovante dans le cadre d’une gouvernance partenariale.
Espaces de coworking et territoires non métropolitains : des relations paradoxales
Authors: Baudelle Guy , Tremblay Diane-Gabrielle , Krauss Gerhard , Le Gall Sébastien , Marinos Clément , Ross Eve
Published: December 2023

Les espaces de coworking ont essaimé hors des grands centres urbains où ils ont été moins étudiés, malgré les espoirs de développement territorial fondés sur eux. À partir d’une enquête internationale attentive aux dimensions territoriale, collaborative et individuelle des entrepreneurs, on montre que ceux fréquentant les espaces hors métropole entretiennent des relations paradoxales avec leur territoire d’accueil. Les résultats ne concordent guère avec les analyses métropolitaines proposées par la littérature. Si le cadre de travail permettant de concilier qualité de vie et accès aux ressources numériques est plébiscité, la dimension collaborative interne reste en effet discrète tout comme les relations avec le milieu local ou les collectivités. Ce paradoxe s’explique par le profil et le parcours professionnel des entrepreneurs, rarement originaires de leur territoire d’implantation. L’impact de leur installation sur le développement local est notable mais ne saurait donc être surestimé.
Some identities involving derangement polynomials and $ r $-Bell polynomials
Authors: Xu Aimin
Published: December 2023

In this paper two kinds of identities involving derangement polynomials and $ r $-Bell polynomials were established. The identities of the first kind extended the identity on derangement numbers and Bell numbers due to Clarke and Sved and its generalizations due to Du and Fonseca. The identities of the second kind extended some of the results on derangement polynomials and Bell polynomials due to Kim et al.
Predictors of Success and Preference for Full Online Distance Education: Insights Moving Forward the New Normal in Education
Authors: Castro Edgar Allan G.
Published: December 2023

The study investigated the critical success factors (CSF) influencing the effectiveness of online distance learning delivery. Effectiveness was measured based on overall student satisfaction, intention to re-enroll, intention to recommend the school, and preference for online learning. The study utilized data from a total of 2,703 students, which accounted for 68% of the entire student population of a higher education institution in the Philippines. Students expressed their satisfaction with the school’s online services, including academic (learning outcomes and delivery), academic support, and student services. They regarded these services as indicative of quality, assessed through an instrument constructed from existing literature. A three-factor model was established through confirmatory factor analysis, and path relationships were scrutinized using covariance-based structural equation modeling with AMOS. Effect size analysis was used to confirm the regression weights and P-values. Results show that the delivery of learning had the most influence as a predictor of success and may be the only crucial factor for all indicators of success. Learning outcomes, academic support, and student services provided online did not show any significant effect or register any effect on all success indicators. The latter supports the premise that investing in ICT infrastructure and educational technology tools contributes, but it does not guarantee success. Moving forward, fully online distance learning, if designed appropriately, has the potential to become a prominent method of conventional education, rather than just a temporary solution during a crisis.
Biogas Production from Palm Oil Mill Effluent Using Dielectric Barrier Discharge Integrated with the Aerated Condition: Evaluation Based on Stoichiometric Simulation and Kinetic Study
Authors: Desmiarti Reni , Rosadi Maulana Yusup , Hazmi Ariadi , Rahman Muhammad Miftahur , Naldi Nofri , Fajri Joni Aldilla
Published: December 2023

In this study, the performance of dielectric barrier discharge (DBD) integrated with the aerobic process with the input voltage of 20 and 25 kV on the production of biogas; methane (CH4), hydrogen (H2), and carbon dioxide (CO2) from palm oil mill effluent (POME) were investigated. The DBD and DBD integrated with the aerobic process (DBD + aerobic) treatment was also simulated using the theoretical stoichiometric of POME (in terms of carbohydrate) and the kinetic study using the first- and second-order kinetic model. The results showed only 0.58, 0.39, and 0.97 mol/L of CH4, H2, and CO2, respectively, generated from the simulation model, which underperformed those experimental results. This may be due to the low concentration of carbohydrates given by the simulated stoichiometric reaction. However, both simulation and experimental results showed a rapid increase in biogas concentration in the initial reaction time in the DBD + aerobic reactor with an input voltage of 25 kV. The results showed that DBD + reactor produced CH4, H2, and CO2 thirteen, twenty-three, and three times higher than DBD alone, respectively. This suggests that good performance was observed when the DBD was integrated with the aerobic process under the optimum input voltage. The study can give information on the optimum condition in a lab scale to produce CH4, H2, and CO2 from POME.

Published: December 2023

The Ultrahigh strength Q&P automotive steel, i.e. QP980, has a broad application prospect in lightweight due to its high strength and good plasticity. In this study, the range of heat input (30 ~ 40 J/mm) was selected by controlling laser power in laser welding of QP980 in order to investigate the microstructure and properties of welded joint. At the heat input of 30 ~ 40 J/mm, the joint of QP980 had acceptable penetration. The weld widths were 417.93 mm, 582.02 mm and 521.56 mm, respectively. The macroscopic morphology of the joint is hourglass type. The microhardness of the welded joint hardening zone is higher than that of the base metal, and the maximum value is 519 HV0.5. When the heat input is 35 J/mm, the tensile strength of the welded joint is 1109 MPa. The maximum joint factor is 91.88 %. The fracture is close to the base metal. A large number of dimples are observed on the fracture surface, implying as ductile fracture. Based on the EBSD results, the proportion of low angle grain boundary was consistent with mechanical properties. A large number of deformation twins are formed in the 35 J/mm sample through deformation, which has a great contribution to the strength of the weld.

Published: December 2023

Green economy and blue economy are essential to applicate. One of the mandatory programs from the Indonesian government is B30, a specification of diesel fuel that has 30 percent of biodiesel content. Based on the biodiesel feedstock specification standard, the free fatty acid content is below 1%. The aim of this research was to produce biodiesel feedstock with high purity of triglyceride from used cooking oil by using batchwise solvent extraction. Batchwise solvent extraction involves the polarity of oil and solvent to separate polar and non-polar lipid fractions. The target of this research was the lowest percentage of free fatty acid and the highest percentage of triglyceride. This method also skipped the general method of refined oil products, such as degumming, neutralization, bleaching, and deodorization. The used cooking oil was mixed with a binary solvent (n-hexane and technical grade ethanol) and a single solvent (food grade ethanol 96% only). Each mixture was stirred at 300 rpm for 15 min and then poured into a separator funnel for 15 min. Polar and non-polar lipid fractions were separated. The non-polar lipid fraction was processed in the same procedure until eight stages. It was found that the batchwise binary solvent extraction produced a non-polar lipid fraction with triglyceride and free fatty acid purities of 88.81% and 2.06%, respectively. Moreover, the batchwise single solvent extraction produced a non-polar lipid fraction with triglyceride and free fatty acid purities of 95.89% and 0.93%, respectively, which is suitable with the standard of biodiesel feedstock below 1%.

Authors: Kumpa Jintana , Kongkarat Somyote
Published: December 2023

With an aim to utilize the local-based waste materials, this research investigated the production of mill scale - biomass pellet (MBP) as an alternative charged material for EAF steelmaking. Rubber tree bark (RTB) is one of the major biomasses in Thailand, consisting of carbon and hydrogen as the main compositions. The carbon derived from RTB was mixed with coal into five different ratios. Pure coal and RTB were employed for comparison. Seven carbonaceous samples were blended with mill scale at a C/O molar ratio of 1:1 to produce MBP, namely Coal, blend#1 – blend#5 and RTB. The reduction of MBP was investigated in a horizontal tube furnace under argon atmosphere at 1550°C for 15 and 30 minutes. The obtained products were iron droplets and residual black powder of unreacted oxides. Quantities of reduced iron from the MBP of blend#1 – blend#5 was about 58 – 61 wt% after 30 minutes, while it was 62 wt% and 57 wt% for coal and RTB, respectively. Degree of metallization (DOM) for blend#1 – blend#5 was between 78.1 – 81.7%, while it was 82.7% and 83.3% for coal and RTB. This research offers the possible method to utilize mill scale and RTB biomass toward circular economy.
Low Tool Wear Cutting Method Using H2O Radical
Authors: Toyota Hiromichi , Shiraishi Ryoya , Goto Hidekazu , Zhu Xia , Iwamoto Yukiharu , Tamura Syoma
Published: December 2023

Tool wear is an important problem when cutting hard-to-cut materials such as stainless steel and nickel alloys. This unignorable disadvantage is caused by the diffusion of dissociated carbon atoms to the surface layer of the tool tip during the cutting process, and this has been confirmed by SEM/EDS analysis of worn tool tips. In this study, a novel cutting method is proposed in which chemically activated H2O molecules are introduced to the cutting tool tip in order to prevent tool wear by removing dissociated carbon atoms on the surface layer of the tool tip. In cutting experiments, stainless steel X5CrNi 18-10 (JIS SUS304), a cemented carbide tool tip, cutting oil, steam, and Ar plasma were used. Ar plasma was used for raising the steam temperature around the tool tip and chemically activating H2O molecules. From the results, the dissociated carbon and constituted knife edge were mostly removed by H2O steam and cutting oil without Ar plasma. However, in some cases using Ar plasma, the workpiece melted and tightly adhered to the cutting face of the tool tip. This suggests that the H2O steam temperature should be suitably controlled so as to remove carbon atoms effectively from the cutting face of the tool tip.
SOCIALISMO? RIFLESSIONI SUL LIBRO DI FRANCO ARCHIBUGI: IL PRIVATO COLLETTIVO. UN NUOVO SOCIALISMO STA CAMBIANDO IL PAESE
Authors: Milana Carlo
Published: December 2023

Il riconoscimento che i sistemi socio-economici si evolvono al di fuori di qualsiasi corso storico predeterminato e che difficilmente sopravvive alcuna contestazione del tradizionale paradigma socialista (marxista) fanno sì che l'ultimo libro di Franco Archibugi assomigli ad una nuova rielaborazione del concetto di sistemi socio-economici misti. . Questo libro stimola anche riflessioni su come sistemi eterogenei orientati al “profit” e al “non-profit” possano coesistere e persino cooperare, suggerendo così che il concetto genuinamente rivoluzionario di “socialismo liberale” di Carlo Rosselli può diventare un’iniziativa spontanea. realtà compiuta nelle economie più avanzate.
Infliximab as successful treatment option in a case of adenosine deaminase 2 deficiency
Authors: Ates M.B. , Karup S. , Ugurlu S.
Published: December 2023

Deficiency of adenosine deaminase 2 (DADA2) is a recessively inherited autoinflammatory disease characterized by systemic inflammation and immunodeficiency. Infliximab proved to be favorable in the treatment of this condition. This case report is concerned with a DADA2 deficient patient treated with infliximab. This is a rare case of DADA2 in a 32-year-old female patient. The patient was admitted with a clinical presentation of erythema, ulcers, and pruritus on both legs and ankles, accompanied by red ulcerative oral lesions, fatigue, malaise, and dizziness. The patient’s genetic analysis was positive for DADA2. Treatment based on TNF-α inhibition was highly effective for this patient. We used laboratory testing and punch biopsy as differential diagnostic tools, where antinuclear antibody positivity, high prolactin levels, and high serum C-reactive protein were observed. The punch biopsy revealed both orthohyperkeratosis and parahyperkeratosis of the dermis, diffuse core fragments, plasma in the stratum corneum, and hypergranulous acanthosis. DADA2 treatment is centered on tumor necrosis factor α suppression. Although high-dose systemic glucocorticoids can reduce inflammation in the initial stages of the disease, most patients have a resistant or relapsing response to tapering attempts. The prevalence of undiagnosed cases of autoinflammatory diseases is anticipated to diminish with the growing awareness of them.
Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis recurrence temporally associated with allergen-specific immunotherapy in a female adolescent: a case report
Authors: Granjo Morais C. , Martins A. , Ganhão S. , Aguiar F. , Rodrigues M. , Brito I.
Published: December 2023

Periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome is the most common periodic fever syndrome in pediatric patients. It is clinically characterized by fever flares lasting 3-7 days, reappearing every 2-8 weeks with a distinctive clockwork regularity. PFAPA generally begins before 5 years of age and usually ceases 3-5 years after onset. Recurrences may be observed in adolescence and adulthood in up to 20% of cases. The authors aim to describe a case of PFAPA recurrence in adolescence temporally associated with allergen-specific immunotherapy (ASIT). A 16-year-old female patient was referred to the rheumatology unit due to recurrent episodes of fever one month after initiating ASIT for allergic rhinitis. These episodes occurred every 4 weeks and lasted 3 days. During these episodes, she also presented with a sore throat, tonsillar exudates, and cervical lymphadenopathy. Abortive treatment with oral prednisolone was attempted in these episodes, with complete resolution of fever after a single dose. After reviewing her medical background, she had previously experienced febrile episodes accompanied by aphthous ulcers and tonsillar exudates occurring every 7-8 weeks from age 2-7. The etiopathogenesis of PFAPA remains uncertain. Environmental triggers, particularly those with immunomodulator effects, may interfere with the immune responses responsible for PFAPA occurrence, but the mechanisms are still unclear. The authors describe the first report of the reappearance of PFAPA flares, possibly due to ASIT. Further studies are needed to fully clarify if ASIT constitutes a true environmental trigger of PFAPA.
Risk of Low Energy Availability, Disordered Eating, and Menstrual Dysfunction in Female Collegiate Runners
Authors: Dambacher Leah , Pritchett Kelly , Pritchett Robert , Larson Abigail
Published: December 2023

Context

Collegiate female distance runners may be at risk for low energy availability (LEA) due to increased exercise energy expenditure with or without decreased energy intake. Furthermore, this population has an increased risk of disordered eating (DE), which can lead to LEA and negative health consequences, such as menstrual dysfunction (MD).

Objective

To (1) investigate risk of LEA, DE, and MD; (2) compare DE, training volume, and weight dissatisfaction between female collegiate runners at risk and those not at risk for LEA; and (3) compare the risk for LEA between National Collegiate Athletic Association Division I, II, and III female collegiate runners.

Design

Cross-sectional study.

Setting

Free-living conditions.

Patients or Other Participants

A total of 287 female runners who competed on a National Collegiate Athletic Association Division I, II, or III cross-country team, track team, or both.

Main Outcome Measure(s)

Participants completed a 45-item questionnaire that included the Low Energy Availability in Females Questionnaire (LEAF-Q) and the Disordered Eating Screen for Athletes (DESA-6).

Results

We observed that 54.4% (n = 156) of runners were at risk for LEA (LEAF-Q score ≥ 8), 40.8% (n = 117) were at risk for DE (DESA-6 score ≥ 3), and 56.5% (n = 162) reported MD (LEAF-Q menstrual function subsection score ≥ 4). Athletes at risk for LEA had higher DESA-6 scores than athletes not at risk for LEA (P < .001). Athletes at risk for LEA had greater weight dissatisfaction than those not at risk for LEA ( = 15.92, P = .001). Higher weekly training volume was not associated with risk for LEA ( = 4.20, P = .11).

Conclusions

A substantial percentage of collegiate female runners were found to be at risk for LEA and DE and to report MD. These findings demonstrate that the risks for DE, MD, and weight dissatisfaction are associated with risk for LEA.

Published: December 2023

A neonate, with complete fibrous congenital alveolar synechiae and amniotic band syndrome affecting the upper and lower limbs, was posted for surgical release of synechiae under anaesthesia. A neonate with no mouth opening poses many anaesthesia challenges. The surgical and anaesthesia plan was discussed with ear, nose and throat surgeons. Topicalisation of airway, small aliquots of intravenous (IV) ketamine and propofol and sevoflurane inhalation helped achieve adequate depth of anaesthesia to carry out flexible intubating video endoscope-guided nasotracheal intubation successfully. Post-surgery, a check laryngoscopy with D-Blade of C-MACR (Karl Storz Video Macintosh Laryngoscope) video laryngoscope revealed a Cormack Lehane view of grade IV. The trachea was not extubated on table and the baby was shifted back to the neonatal intensive care unit with pressure support ventilation and followed by tracheal extubation next morning. Rest of the course for the baby was uneventful. Anticipation, planning, preparedness, vigilance and team work during anaesthesia management led to a successful outcome in this case.
Anaesthetic Challenges in Recurrent Respiratory Papillomatosis with Unyielding Lesion
Authors: Srinivasan Suganya , Senthilnathan Muthapillai , Ganesan Sivaraman , Mohan VK
Published: December 2023

Recurrent respiratory papillomatosis (RRP) is one of the most common laryngeal lesions in children. A 14-year-old female presented with complaints of a change in voice and noisy breathing. She underwent excision of laryngeal papillomatosis thrice before. Fibreoptic laryngoscopy revealed that the lesion was occluding the entire glottic chink except for a small opening through which she was breathing. As there was a risk of seeding of the distal airway following tracheostomy, the initial plan of tracheostomy was deferred. Anaesthesia was induced with sevoflurane. C-MAC™ laryngoscopy revealed that the entire glottic chink was occupied with the papillomatous lesion, and no opening was visualised. The lesion could not be negotiated with a 4 mm endotracheal tube and started bleeding. Immediately, surgeon was asked to perform a tracheostomy. With each recurring incidence of RRP, the probability of the papilloma’s non-yielding nature may increase, making the negotiation of the lesion impossible.
Anticipated and Experienced Pain Associated with Root Canal Treatment in a Teaching Dental Hospital in India: A Survey
Authors: Gupta Natasha , Singh Neelam
Published: December 2023

Introduction:

The pain associated with endodontic therapy brings about a lot of fear and anxiety. This fear sometimes leads to patient avoiding to get the appropriate treatment and save the tooth. It becomes very important that the patient is well guided so he can resort to save the tooth rather than extract it. This study was undertaken to evaluate the pain which is felt before getting the treatment (anticipated pain) and also pain which was actually experienced (experienced pain).

Methodology:

This pilot study was conducted on a population of 100 in government dental colleges and hospitals. The consent was taken, and two questionnaires were got filled pretreatment and posttreatment. These questionnaires used a Modified Visual Analog Scale (0–3, 0 = no pain, 1 = mild, 2 = moderate, and 3 = severe).

Results:

The data were analyzed using the Chi-square test and Kruskal–Wallis test. To statistically compare anticipated and experienced pain scores, the Wilcoxon test was used.

Conclusions:

This study showed that the anticipated pain was more than experienced pain. The two major reasons for the patients to withdraw from getting the treatment are the cost factor and the pain associated while getting the treatment done. Good anesthesia techniques help reduce the pain experienced and hence reduce the overall anxiety of the patient.
Nonsyndromic Gemination-associated Microdontia: A Report of an Unusual Case
Authors: Ghorai Laboni , Bhattacharya Mayukh
Published: December 2023

Tooth gemination is a dental anomaly that results from an incomplete attempt of a single tooth germ to separate during morphodifferentiation stage of odontogenesis, and it usually exhibits a large bifid crown with a single common root and root canal. This developmental anomaly more commonly affects primary dentition than the permanent, with an infrequent occurrence reported of posterior teeth. Among the posterior teeth, mandibular second premolars have reportedly shown an elevated possibility of agenesis, delayed odontogenesis, and variability of crown morphology. Both unilateral and bilateral cases of isolated macrodontia of mandibular second premolar secondary to gemination or fusion have been reported, but there is no evidence of microdontia associated with gemination in the literature till date. This case presentation reports an unusual case of isolated unilateral gemination-associated microdontia of the left mandibular second premolar in a nonsyndromic patient.

Authors: Nair Athira K. , Vijayaraghavan Vasantha , Mundhe Darshana , Bhave Rohan P. , Pol Bhushan , Jadhav Madhura Kad
Published: December 2023

Background:

Due to the close proximity to the oral cavity, shade guides are prone to contamination with saliva. Hence, disinfection of shade guides is important to prevent cross infection in clinics. This study has compared and evaluated the color change in VITA shade guide and the WALDENT shade guide after disinfecting with 70% isopropyl alcohol.

Objectives:

The objective of this study was to compare and evaluate the amount of color change in the VITA shade guide and WALDENT shade guide after disinfecting them with 70% isopropyl alcohol for the simulated time of 6 months and 1 year.

Materials and Methods:

Four commonly used shade tabs, namely A2, A3.5, B2, and C1 of two shade guides – VITA Classical Shade Guide and Waldent shade guides – were chosen for this study. VITA Easyshade spectrophotometer measured the shade, and the values were recorded in the International Commission on Illumination L*a*b* Scale. Baseline values of 8 shade tabs were obtained followed by surface disinfection using 70% isopropyl alcohol using gauze. The testing process was done to simulate a 6-month period and 1-year period.

Results:

Unpaired t-test was used for statistical analysis. It was found that shade tabs underwent significant changes in short period of time.

Conclusion:

Within the limitations of this study, it was found that shade guides undergo significant changes in color when disinfected with 70% isopropyl alcohol during a simulated period of 6 months.

Clinical Significance:

If shade guides are not periodically evaluated using a control (preferably unused) shade guide, they may have a profound impact on resulting restoration.
Cost-minimization Analysis in Iron-deficiency Anemia Comparing Intravenous Ferric Carboxymaltose to Standard of Care in Pregnant Women in Algeria
Authors: Aladham Lama , Benmouhoub Nacera , Bradai Mohamed , Dammene-Debbih Amel , Frigaa Issam , Layaida Karim , Mahi Lamine
Published: December 2023

INTRODUCTION:

Anemia due to iron deficiency is frequent during pregnancy and increases morbidity and mortality of mothers and infants. The objective of this study was to assess the economic consequences of intravenous ferric carboxymaltose (FCM) in anemic pregnant women in Algeria.

METHODS:

The economic analysis was a cost-minimization model comparing the strategy for treating pregnant women with intravenous iron sucrose to FCM. The perspective of Algerian health-care providers was adopted to calculate costs savings. Cost related to treatment of iron-deficiency anemia included infusion, iron workup, medical time, iron vials acquisition, and absenteeism. Data were obtained mostly from available scientific literature and public health data and were validated by expert opinion. A budget impact model was also developed for the population of Algerian women needing intravenous iron treatment to evaluate the gross impact on payers’ budget if FCM treatment was prescribed.

RESULTS:

Treatment of pregnant women with iron-deficiency anemia (mean weight, 65 kg; hemoglobin 7.5 g/dL) needed 7 hospital visits and 14.9 doses for iron sucrose treatment to be compared to 2 hospital visits and 2 doses for FCM treatment. Total cost was Algerian dinar (DZD) 69,222 per patient for iron sucrose and DZD 57,452 for FCM (cost savings per patient: DZD 11,769, i.e., 17%). If all 192,000 pregnant Algerian anemic women eligible for injectable iron treatment received FCM, global cost savings would be DZD 2,259,820,627 per year.

CONCLUSION:

This economic model suggests that FCM is a cost-saving treatment compared to standard iron sucrose treatment in pregnant women with iron-deficiency anemia in Algeria.

Authors: Goswami Arunima , Bordoloi Bharadwaj , Goswami Pinky , Tandon Aanchal
Published: December 2023

Photodynamic therapy (PDT) is considered a contemporary effective treatment option for oral premalignant lesions. This systematic review aims to evaluate the usefulness of PDT for the treatment of oral premalignant lesions. The focused question was “Is PDT effective in the treatment of oral premalignant lesions?” A literature search was made in PubMed/Medline and Google Scholar databases using different combinations of the following keywords: photodynamic therapy, oral premalignant lesions, oral leukoplakia (OL), erythroplakia, oral erythroleukoplakia (OEL), oral verrucous hyperplasia (OVH), and oral lichen planus (OLP). Review articles, preclinical studies, case reports, commentaries, letters to the editor, unpublished articles, studies on photodynamic therapy used in areas other than oral cavity, and articles published in languages other than English were excluded. The relevant information were summarized. Initial results were 23. Twenty-two studies were included. Oral premalignant lesions, which were investigated, were OL, erythroplakia, OEL, OVH, and OLP. The studies used either laser light or light-emitting diode. Photosensitizers used were aminolevulinic acid, chlorine-e6, meta-tetrahydroxyphenylchlorin, methylene blue, toluidine blue, methyl 5-aminolevulinate cream, and phenothiazine chloride. Study outcomes and recurrence rates were evaluated. PDT is an effective treatment option. Topical PDT is an easy-to-perform technique, well-tolerated treatment with encouraging achievements in the treatment of premalignant lesions.
Predictors of Periodontal Diseases in the Student Population of Caucasus International University: A Study of Risk Factors and Oral Health Optimization
Authors: Tsitaishvili Lela , Jikia Tamar
Published: December 2023

Introduction:

Periodontal diseases cause esthetic and functional disorders having an impact on oral and general health and the psychological and social status of a person. “Unhealthy oral cavity” as a problem is particularly painfully perceived by young patients, having concern predominantly about their appearance and personal social connections. The migration of foreigners to Georgia has made a great impact on dental referrals in Georgia last years. Foreign populations are different in lifestyle, diet, dental practices, and oral hygiene habits. They live, study, or work and are closely integrated into Georgian society; subsequently, their oral health may influence periodontal diseases’ overall prevalence in the country.

The Aim of the Study:

The aim of this study was to assess the periodontal status of Caucasus International University (CIU) students of different nationalities, study the risk factors, and oral health optimization by planning and implementing preventive measures.

Methods:

This was randomized research conducted on 820 students aged 18–35 years, including 370 Georgians and 450 foreigners, 369 boys and 451 girls.

Results:

Unhealthy periodontal tissues were observed in 46.3% of boys and 44.6% of girls. 34.8% of Georgians and 66.4% of foreigners were suffering from gum bleeding. Bleeding on probing of II and III degrees was common in the 1st (18–25) age group (40.5% and 31.0%, respectively) and I and II degrees in the 2nd (26–35) age group (39.4% and 44.9%, respectively).

Conclusion:

Findings indicate a rather high prevalence of dental plaque-induced gingivitis in the CIU student population. Students do not receive adequate dental care and have negative attitudes toward oral hygiene skills and dental services. Management of periodontal problems with an emphasis on oral hygiene enhancement and promotion of oral prophylaxis accentuated the role of the university dental clinic in providing scientific and clinical experience to the CIU students.
Awareness of Periodontal Treatment Modalities among Dentists of Bathinda District of Punjab: A Questionnaire Survey
Authors: Kaur Prabhsimar , Arora Pooja , Singla Ruby
Published: December 2023

Introduction:

Periodontal disease is a chronic, inflammatory disease that can lead to various destructive changes in the periodontium as well as systemic health. Periodontology is a fast-growing dental specialty ranging from new advances in diagnosis and treatment. Despite these new advances, the knowledge of periodontal diagnosis and treatment in the minds of general dentists is still lagging. General dentists need to be aware of how to diagnose and treat periodontal disease in the early stage, so there is a need for periodontal health awareness programs to be held at regular intervals. This questionnaire study aims to identify the knowledge regarding periodontal diagnosis and treatment modalities available for patients among practicing dental professionals.

Materials and Methods:

Two hundred dental practitioners having their dental clinics in any area of Bathinda, Punjab, were interviewed through a questionnaire. Dental practitioners with minimum qualifications of BDS and experience of at least 1 year in the private clinical setup were included in the study. The questionnaire consisted of 15 questions ranging from the chief periodontal complaints of the patients, availability of the treatment, and different techniques used to the level of satisfaction of private dentists after the periodontal treatment.

Results:

There is enough awareness regarding periodontal problems and its management, as 157 dentists out of 200 refer their patients to periodontists. General dentists perform scaling and root planing, advice oral hygiene instructions, provide diet counseling, and refer to periodontists only for surgical procedure. Lack of maintenance and awareness toward oral hygiene measures was identified by the survey as the chief factor for recurrence of periodontal disease.

Conclusion:

Such studies performed at different time intervals can provide an idea about the changing trends and patterns of dental treatment performed by general dental practitioners.

Background and Aims:

Hypotension following subarachnoid block (SAB) for lower segment cesarean section (LSCS) has adverse fetal and maternal implications. Perfusion index (PI) has been used for assessing peripheral perfusion dynamics. This study aimed to determine whether a baseline PI can predict hypotension after spinal anesthesia for LSCS.

Materials and Methods:

In this prospective, observational study, 152 term parturients were divided into two groups: Group I (PI of ≤ 3.5) and Group II (PI >3.5). SAB was performed using bupivacaine 0.5% (hyperbaric) 10 mg with dexmedetomidine 5 μg. PI, vital parameters, and correlation between baseline PI and hypotension were observed. Receiver operating characteristic (ROC) curve was plotted for PI and the occurrence of hypotension. Statistical analysis was performed using Chi-square test, independent sample t-test, Mann–Whitney U-test, and regression analysis with Spearman’s rank correlation coefficient test.

Results:

The incidence of hypotension was higher in Group II (57.89%) compared to Group I (18.42%) (P < 0.0001). The correlation between baseline PI >3.5, the number of episodes of hypotension, and the total dose of mephentermine required were also significant. The sensitivity and specificity of baseline PI of 3.5 to predict hypotension were 72.37% and 81.58%, respectively. The area under the ROC curve for PI to predict hypotension was 0.830.

Conclusion:

Parturients with baseline PI >3.5 are at higher risk of developing hypotension following SAB compared to those with baseline PI ≤3.5; hence, PI is a safe and reliable device for predicting hypotension following SAB.
Duane syndrome: An overview on the current management
Authors: Prasad Priyanka , Saxena Abhyuday , Saxena Rohit
Published: December 2023

Duane syndrome is one of the most common restrictive congenital strabismus characterized by variable horizontal duction deficits with globe retraction and shoots on attempted adduction and narrowing of the palpebral aperture. It is now listed as a congenital cranial dysinnervation disorder. The disease is usually unilateral with female preponderance. Basic etiopathogenesis involves dysinnervation of the lateral rectus (LR) due to aplastic/hypoplastic abducens nucleus with a secondary aberrant supply to the LR by the medial rectus (MR) subnucleus of the oculomotor nerve. Diagnosis of the disease is usually clinical. Due to the variable presentation of the disease, surgical management is a challenge and has to be individualized to achieve alignment in the primary gaze, reduction in globe retraction, upshoots and downshoots, and correction of any abnormal head posture. Differential recessions of the lateral and MR muscles are done to correct esotropia or exotropia in the primary gaze. For globe retraction and shoots, Y-split or periosteal fixation of the LR muscles is done depending on the severity.

Published: December 2023

PURPOSE:

To describe three anterior segment dysgenesis disorders with infantile corneal opacities, namely, congenital hereditary endothelial dystrophy (CHED), primary congenital glaucoma (PCG), and Peters anomaly (PA) in terms of clinical characteristics, histopathology, genetic association, and diagnostic imaging profiles using imaging modalities such as ultrasound biomicroscopy (UBM) and microscope-integrated intraoperative optical coherence tomography (i-OCT).

MATERIALS AND METHODS:

Seventy-four eyes with 22 eyes of CHED, 28 eyes of PA, and 24 eyes of PCG were clinically evaluated and underwent imaging using UBM and i-OCT. Corneal buttons of 16 operated patients underwent histopathological analysis, while genetic analysis was done in 23 patients using whole-exome sequencing.

RESULTS:

Corneal diameters (CD) and UBM parameters like anterior chamber depth (ACD), iris thickness (IT), and ciliary body (CB) thickness revealed a statistically significant difference between the three categories. In PA, 9 eyes had a third rare phenotype with only a posterior corneal defect with no iris adhesions. Genetic mutations were seen in all tested patients with CHED, in 83.3% of patients with PCG, and in 80% of patients with the third type of PA. i-OCT helped in the characterization of corneal opacity, identification of posterior corneal defects, iridocorneal adhesions, and contour of Descemet’s membrane.

CONCLUSION:

Overlapping phenotypes of the above disorders cause a diagnostic dilemma and parameters like CDs, UBM ACD, IT, and CB thickness help differentiate between them. i-OCT can help in classifying the diseases in a high resolution, non-contact manner, and can better delineate corneal characteristics. The rare third type of PA phenotype may have a genetic association.

The relentless pursuit of creating intelligent robotic systems has led to a symbiotic relationship between human inventiveness and artificial intelligence (AI). Artificial intelligence is a theory.  It is the development of computer systems that are able to perform tasks that would require human intelligence. This abstract explores the pivotal role that AI plays in advancing the capabilities and applications of robotic systems.  The integration of AI algorithms and machine learning techniques has launched robotics beyond mere automation, enabling machines to modify, alter, adjust, learn, and interact with the world in ways previously deemed science fiction. Design fictions that vividly imagines future scenarios of AI or robotics in use offer a means both to explain and query the technological possibilities. Examples of these tasks are visual perception, speech recognition, decision-making, and translation between languages.   The three key dimensions of   AI’s role in robotics are Cognitive Augmentation, Human-Robot Collaboration, and Autonomous Intelligence. The abstract also discusses the societal implications of this AI-driven advancement in robotic systems, including ethical considerations, job market impacts, and the democratization of access to advanced technology. The convergence of human intellect and artificial intelligence in robotics marks a transformative era where machines become not just tools, but companions, collaborators, and cognitive extensions of human capabilities.  Researchers are taking inspiration from the brain and considering alternative architectures in which networks of artificial neurons and synapses process information with high speed and adaptive learning capabilities in an energy-efficient, scalable manner. The indispensable role of AI in shaping the future of robotic systems and bridging the gap between human potential and machine capabilities is highlighted. The major impact of this synergy reverberates across industries, promising the world where robots become not just mechanical contraptions / defective apparatus but intelligent partners in our journey of progress.

Published: December 2023

Artificial intelligence (AI) is transforming how we work and make choices, but it also poses ethical and societal issues including algorithmic discrimination and dehumanization. It is critical to take into account corporate culture, emotional intelligence, cooperation, communication, and constant learning when using AI systems in the workplace. It has been demonstrated that emotional intelligence increases AI adoption, efficacy, and performance across a variety of sectors. But ethical concerns and trouble making decisions are also important. Effective collaboration, communication, and corporate culture are crucial for successful AI adoption, and continuing learning and development are essential for enhancing decision-making abilities. AI ethics in the workplace necessitate a comprehensive strategy that considers both technical and non-technical aspects. This study looks at the benefits of emotional intelligence, moral concerns, effective stakeholder and IT specialist engagement, organisational culture, and potential threats of artificial intelligence (AI) in decision-making. The study underlines the value of continuous AI learning and development.

Распределение секретных ключей в квантовой сети с доверенными промежуточными узлами
Authors: Arbekov I M , Molotkov Sergei Nikolaevich
Published: December 2023

Базовое распределение секретного ключа в квантовой криптографии осуществляется в конфигурации точка-точка. Эта технология неприменима в квантовых сетях, где требуется передавать ключи на большие расстояния. В настоящей работе предлагается процедура переноса внешнего секретного ключа через промежуточные доверенные узлы с использованием $\varepsilon_{i}$-секретных ключей, полученных на отдельных сегментах сети. Показано, что при переносе изначально $\varepsilon_{K}$-секретного внешнего ключа с крайнего узла на следующий доверенный узел его секретность становится равной $\varepsilon_{K}+\varepsilon_{1}$. Результат обобщается на линии связи из $L$ сегментов с оценкой секретности $\varepsilon_{L}=\varepsilon_{K}+\sum_{i=1}^{L}\varepsilon_{i}$. Установлено, что при любых измерениях подслушивателя, приводящих к классическим вероятностным распределениям, сложность восстановления передаваемого ключа в классе алгоритмов перебора наиболее вероятных ключей определяется параметром секретности $\varepsilon_{L}$.
Geodesic flow on an intersection of several confocal quadrics in $\mathbb{R}^n$
Authors: Belozerov Gleb Vladimirovich
Published: December 2023

By the Jacobi-Chasles theorem, for each geodesic on an $n$-axial ellipsoid in $n$-dimensional Euclidean space, apart from it there exist also $n-2$ quadrics confocal with it that are tangent to all the tangent lines of this geodesic. It is shown that this result also holds for the geodesic flow on the intersection of several nondegenerate confocal quadrics. As in the case of the Jacobi-Chasles theorem, this fact ensures the integrability of the corresponding geodesic flow. For each compact intersection of several nondegenerate confocal quadrics its homeomorphism class is determined, and it turns out that such an intersection is always homeomorphic to a product of several spheres. Also, a sufficient condition for a potential is presented which ensures that the addition of this potential preserved the integrability of the corresponding dynamical system on the intersection of an arbitrary number of confocal quadrics.

Published: December 2023

Изучается семейство неавтономных обобщенных уравнений типа Льенара. С использованием обобщенных преобразований Зундмана рассмотрена проблема эквивалентности для данного семейства уравнений и уравнений Пенлеве-Гамбье типа I. Найдены четыре критерия эквивалентности, которые задают четыре новых семейства интегрируемых уравнений типа Льенара. Показано, что полученные критерии применимы для построения общих аналитических решений в переменных бегущей волны для некоторых классов уравнений реакции-диффузии. Полученные результаты также иллюстрируются несколькими другими примерами интегрируемых неавтономных уравнений типа Льенара.
