Authors: Catalan Eric P. , Vergara Julius T. , Flora Rhea Joy D. , Tupas Mark Joseph C. , Luceño Niel A.
Published: December 2024

This study aimed to explore the potential of upcycling plastic waste by incorporating recycled shredded PET bottles into cement mixtures for pavement bricks. The goal was to address the persistent demand and supply of plastics, which frequently contribute to ocean pollution. By substituting traditional aggregates with recycled PET, the research assessed the water absorption, waste conversion, durability, and practical applications of using plastic-enhanced cement mixtures in construction. Mixture #2 demonstrated good water resistance while being lighter than other mixtures, making it an ideal option for applications where reducing weight is critical without sacrificing too much strength. Mixture #1 had the highest plastic content, making it the most aggressive in terms of plastic waste conversion. However, the elevated plastic proportion affected its durability, suggesting it is best suited for projects prioritizing waste reduction over strength. Mixture #4 emerged as the top performer, showcasing the highest durability. Its equal ratio of sand and plastic provided a well-balanced mix that combined structural integrity with optimal weight and water resistance. This makes it the most suitable choice for heavy-duty pavement blocks that require long-lasting performance. Mixtures #3 and #4 achieved a balanced integration of sand and plastic, leading to solid structural properties. Mixture #3’s moderate durability makes it a versatile choice, while Mixture #4’s superior performance highlights the benefits of a carefully optimized sand-to-plastic ratio.

Alkylphenols (APs) and Alkylphenol Ethoxylates (APEs) are endocrine disrupting chemicals of global environmental concern, yet, there is paucity of data, and no regulation on these chemicals on the Nigerian environment, and the rest of African continent. This study determined occurrence and baseline risks of APs and APEs in water and sediment from River Benue, central Nigeria, using Gas Chromatography-mass Spectrometry (GC-MS). Sum of twenty APs (∑20APs) in water ranged from ND-38.0 ngL-1 during rainy season, and range during dry season was 1.02-5.03 ngL-1. Sum of four APEs (∑4APEs) in water during rainy season ranged from ND-11.1 ngL-1, with the range of ND-1.33 ngL-1 during dry season respectively. ∑20APs in sediment ranged from ND-11.98 ngg-1 d wt during rainy season, with the range of ND-34.4 ngg-1 during dry season. ∑4APEs in sediment occurred in range of ND-0.91 ngg-1 d wt during rainy season, while the dry season APEs occurred in range of ND-8.23 ngg-1 d wt. Risks estimate of APs and APEs in water and sediment were consistently lower than the global ecological and human health risks guidelines, suggesting no immediate threat to the ecosystem or humans. This study provides comprehensive baseline data on the levels and risk assessment of APs and APEs in water and sediment from River Benue (second biggest river in Nigeria) in order to guide regulatory authorities, and intending researchers, hereafter.

Pozitivizmin Türkiye Cumhuriyet Dönemi Eğitim Sistemine Etkisi
Authors: Çakmak Onur
Published: December 2024

İlk olarak Saint Simon tarafından ortaya atılan ve A. Comte tarafından sistemleştirilen pozitivizm; bilimi esas alan, bilim dışı görüşleri, özellikle teoloji ve metafiziği insanlığın gelişimine engel olarak gören bir öğretidir. Pozitivizm öğretisine göre esas alınabilecek tek bilgi türü deneysel verilere dayanan bilgidir. Pozitivizmin başta doğa bilimleri olmak üzere tüm bilim dallarında etkisi görülmüştür. Pozitivizm öğretisi ortaya çıkıp sistemleştikten sonra eğitim bilimsel temelli olarak yapılmaya başlanmıştır. Pozitivizm öğretisinin ülkemize ilk girişi Osmanlı İmparatorluğunun son dönemleri olup pozitivizm Türk aydınları tarafından benimsenen ilk modern ideoloji ve düşünce sistemidir. Pozitivizm Osmanlının son döneminde ülkenin içinde bulunduğu kötü durumdan kurtarmak için bir ideoloji olarak Aydınlar tarafından uygulanmaya çalışılmış ancak gerek zaman yetersizliği gerekse yapılan çalışmaların öze inemeden yüzeysel kalması nedeniyle başarısız olmuştur. Pozitivizm Cumhuriyet kurulduktan sonra, “çağdaş uygarlık düzeyine erişmek için eğitim sürecinde bir ideoloji olarak uygulanmaya başlanılmış ve ülkenin eğitimine çok önemli katkı yapmıştır.

Published: December 2024

Osmanlı Devleti sanayileşme çabaları içinde şirketleşme faaliyetlerine önem vermiştir. Bu doğrultuda çıkardığı bazı düzenlemelerle şirketleşmenin önündeki engelleri kaldırmaya çalışmış, küçük ölçekli işletmelerin birleşerek büyük şirketler hâline gelmesi için fabrika ve şirket kuracak kişilere bedelsiz arsa, vergi muafiyeti gibi destekler vermiştir. Çalışmamızın konusu Osmanlı Devleti’nin sanayileşme ve şirketleşme çabaları dâhilinde bir müteşebbis olarak karşımıza çıkan Vladimir Mirmiroğlu ve kurduğu şirketlerden biri olan Olimpos Ticarî ve Sınaî Osmanlı Anonim Şirketi’nin 1922’ye kadar olan faaliyetleridir. Şirketin kuruluş tarihi İstanbul’un İtilaf Devletleri tarafından işgal edildiği döneme rastlar. Otel, gazino ve birahane gibi işletmelere sahip bu şirketle beraber Mirmiroğlu, aynı tarihlerde dokuz şirket daha kurmuştur. Ne var ki şirketlere ait kuruluş nizamnameleri dışında başka bilgilerin olmaması durumu şüpheli kılar. Diğer taraftan Mirmiroğlu’nun birkaç yıl içinde bütün şirketleriyle bağlantısı kopar. Adının zimmete para geçirmek gibi çeşitli sansasyonlarla anılıyor olması durumu daha ilgi çekici hâle getirir. Çalışmamızın ana kaynağını Cumhurbaşkanlığı Devlet Arşivleri Başkanlığı Osmanlı Arşivi’nde (BOA) bulunan belgeler oluşturmaktadır. Ancak Cumhuriyet Arşivi’nde (BCA) bulunan bazı belgelerden de yararlanılmıştır.
Türk Halk Hikâyelerinde Büyü
Authors: Samur Şifanur
Published: December 2024

Sözün büyüsünden doğan halk hikâyeleri, toplumların kültürel mirası olarak aktarılan ve nesilden nesle uzanan bir yol izlemektedir. Halk hikâyelerinde ele alınan değerler, unsurlar, mesajlar, toplumun değerlerini ve ahlaki prensiplerini, hikâye ve yaşam arasındaki kurguyu temsil etmektedir. Bu makalede halk hikâyeleri örnekleri üzerinden incelenecek olan büyü, olağan akışı değiştirmek ve dönüştürmek, doğaüstü güçlerin yardımıyla sonuca ulaşmak gibi doktrinler içermektedir. Halk hikâyelerinde sıklıkla görülen büyüsel işlemler, doğaüstü güçler ve sembollerle ilişkilendirilmiştir. Büyüsel uygulamalar, daha çok doğaüstü güçlere sahip varlıklara atfedilmekte ve halk hikâyelerinde karşımıza çıkmaktadır. İncelenen halk hikâyelerinin belirlenmesinde ölçüt olarak “popülerlik” niteliği kullanılmıştır. Popüler anlatılardan on tanesinin geneli göstereceği fikrinden hareketle şu on örnek seçilerek incelenmiştir: Arzu ile Kamber, Asuman ile Zeycan, Derdiyok ile Zülf-i Siyah, Elif ile Yaralı Mahmut, Ercişli Emrah ile Selvihan, Ferhat ile Şirin, Hurşit ile Mahmihri, Kerem ile Aslı, Kirmanşah, Tahir ile Zühre hikâyeleridir. Halk hikâyelerinde rastladığımız büyüsel motifler, Türk halkının mistik düşünce ve inançlarını ortaya koymaktadır. Bu bağlamda, halk hikâyelerindeki mistik güçler sayesinde var olan büyüsel bilgilerin geniş bir düzleme yayıldığı ve bu yayılımın büyüsel ritüelleri oluşturduğu tespit edilmiştir.

Comparison of the Effects of Different Decontamination Methods on Staphylococcus Aureus Biofilm
Authors: Açıkgöz Alparslan Ece , Bağcı Ufuk , Kurt Ayşegül
Published: December 2024

Purpose: The current in-vitro study aims to compare the effectiveness of various mechanical decontamination modalities in the elimination of Staphylococcus aureus biofilm from titanium surfaces using qualitative and quantitative techniques.
Materials and methods: A total of 48 titanium discs were inoculated with Staphylococcus aureus and randomly allocated into four experimental groups consisting of control, plastic curettes (PC), ultrasonic-driven plastic tips (UPT), and ultrasonic-driven stainless-steel tips (UST). Following decontamination procedures, colony-forming units and viable biomass were analyzed to identify the biofilm removal efficacy of the treatments and the viability of bacteria remaining on the surface. Biofilm structure was assessed by confocal laser scanning microscopy and scanning electron microscopy. Analysis of variance and post hoc Tukey tests were applied for comparisons.
Results: Reductions in both colony counts and variable biomass following the decontamination procedure were significant in all treatment groups (p=0,000). Although the highest reduction in colony count was determined in the UST and the lowest in the PC group, the difference was not statistically significant between treatment groups (p = 0.246). Nonetheless, the reduction in viable biomass in the UST group was greater than in the UPT and PC groups (p=0.005, p=0.000, respectively).
Conclusion: Ultrasonic-driven instruments are more effective than plastic curettes in removing the biofilm that colonizes the titanium surfaces in the initial stages. Stainless steel tips provide better elimination of microbial biofilm compared to plastic instruments, but they alter the surface topography of roughed titanium surfaces more than plastic curettes.
Clinical Impact of Local Anesthesia on Sedation Stability and Propofol Dosage in Pediatric Dental Sedation
Authors: Kocaoglu Merve Hayriye , Vural Çağıl , Ursavaş Betül Büşra
Published: December 2024

Background: Local anesthesia (LA) is often preferred for stabilization of vital signs, depth of anesthesia and pain control in dental restorations but the efficacy of LA administration during deep sedation is controversial.
Aim: To retrospectively investigate the effects of LA on heart rate, blood pressure, oxygen saturation, depth of anesthesia and total dose of anesthetic drugs given in pediatric patients sedated for dental procedures.
Materials & Methods: Records of 50 healthy children were divided into two groups: Patients who received infiltration LA at the beginning of sedation (Early LA) or who received LA at the end of sedation after completion of restorations (Late LA). Demographic data, hemodynamic data, Bispectral Index (BIS) scores, Ramsey Sedation Scale scores, total propofol dose administered were compared. Since the difference between two quantitative dependent variables did not meet the assumptions of normal distribution, Wilcoxon Signed Rank test was used. Generalized Estimation Models were used to look at the effect of quantitative variables with repeated measures (BIS and Ramsey) on groups.
Results: There was no statistically significant difference between the groups in terms vital signs, depth of anesthesia (BIS (p=0.190) and Ramsey score (p=0.887)), and total propofol dose adjusted for BMI (p=0.59).
Conclusion: The presence of LA during deep dental sedation has no significant impact on vital signs, depth of anesthesia and total amount of propofol used compared to the absence of LA. LA does not contribute to stabilization of dental sedation, but close monitoring of deep sedation prevents drug overdose.

Purpose: To evaluate the usefulness and quality of popular videos about indirect restorations shared by different uploaders on
YouTube and to evaluate the demographic characteristics of the videos.
Materials and Methods: The most commonly used terms related directly to indirect posterior restorations were determined as
"inlay" and "onlay" in this topic. Of the 400 videos (200 for each topic), 40 videos were selected for analysis. Evaluations were
made for each video in terms of the following: (1) number of views, (2) number of comments, (3) days since up-load, (4) number
of ’likes’, (5) Viewing rate; [(number of views/number of days since upload) * 100%], (6) Viewer interaction, (7) Usefulness Index
score, (8) 5-point global quality scale (GQS) criteria.
Results: No statistically significant difference was found among usefulness scores and video sources. (p=0.754). Based on the
usefulness score, 20% were classified as good, 40% as poor, and 40% as moderate. No statistically significant difference was found
among primary purpose of videos and video sources. (p=0.754). The greatest number of videos (42.5%) was uploaded by dentists
(n=17). When the primary purpose is evaluated for the videos uploaded by dentists, the highest numerical value was determined as
education for health professionals (52.9%) (n=9).
Conclusions: The contents of YouTube videos regarding the indications and production stages of inlay and onlay restorations need
to be revised according to our evaluation criteria. The number of educational videos providing detailed content and information to
patients should be increased.

Authors: Yılmaz Serkan , Durmaz Yılmaz Özden Melis , Canger Emin Murat
Published: December 2024

Purpose: After the loss of teeth, alveolar bone begins to resorb due to disappearance of the stimulus being applied by the teeth to the alveolar bone. This situation is termed as residual ridge resorption. The aim of this study is to determine the amount of alveolar bone resorption occured in the maxilla and mandible of the patients having Kennedy Class II edentulousness and the distribution of it according to age groups.
Material and Methods: The study was carried out on the panoramic radiographs of 122 individuals (60 mandible, 62 maxilla). Vertical measurements were made at 10 sites (central incisors, first premolars and molars at the left and right of both jaws). The difference of the measurements according to the group and demographic variables was analyzed with the independent groups independent-t and one-way ANOVA tests. Also, dentate and edentulous measurements according to the group and demographic characteristics in the group interaction was analyzed with the repeated ANOVA test.
Results: When the edentulous regions were considered, the vertical height values of the mandible were lower than maxilla. Also, statistically significant difference was detected in the maxillar premolar region of the edentulous regions. According to gender, womens’ vertical height results were found to be lower than men and the vertical heights of the 6-12 months group were higher than 12-24 months group.
Conclusions: According to these results, we think that the patient should be directed to implant rehabilitation in order to prevent bone loss, especially in edentulous patients in the maxillary premolar region.

Purpose: To compare the adaptation and microleakage of CAD/CAM inlay restorations using conventional or ultrasonic finishing equipment and their combinations.
Materials & Methods: Inlay cavities were prepared on 66 extracted human lower first molar teeth using one of the following finishing methods: Group I: straight fissure diamond bur; Group II: fissure diamond bur and ultrasonic tip; Group III: 6º tapered conical diamond bur; Group IV: 6º tapered conical diamond bur and ultrasonic tip. Inlay restorations milled from feldspathic ceramic blocks were cemented with resin cement. Adaptation and microleakage of the restorations were evaluated by micro-CT. The adaptation of the restorations was evaluated in four areas and five determined points. The differences between the finishing methods were statistically evaluated at each measurement point.
Results: The adaptation of the restorations differed between 1.07 and 330.71 µm. Statistical differences were observed in the marginal and internal adaptation of ceramic inlay restorations due to the finishing method used at some points of the ceramic and cavity interface. However, the microleakage values between the finishing methods did not show a statistical difference.
Conclusion: According to the results of this study, the microleakage of the ceramic inlay restorations is not affected by the finishing method used. However, the adaptation of the restoration could be affected by the finishing method, depending on the area.
Clinical Significance: Preparations for inlay restorations prepared with these special burrs and ultrasonic instruments created better marginal fit, which could result in more successful ceramic inlays.

Authors: Alaçam Aylin , Gögen Hakan
Published: December 2024

Purpose: The positional changes of the tongue due to fixed appliance therapy, the relationship between the positional changes of lower incisor, the tongue and the attribution of this relationship was investigated.
Materials & Methods: In this retrospective study, lateral cephalograms of pre and posttreatment records were evaluated. According to the mathematical differences of 1-NB parameters, subgroups namely; retrusion and protrusion groups were formed. Pretreatment measurements were performed from horizontal and vertical reference planes defined, posttreatment measurements were evaluated with the transportation of these reference lines using the total structural superimpositional method. The positional and linear dimensional changes of the tongue were evaluated using Rakosi tongue analysis with a modification of the reference line. Cephalometric tongue images were digitized and the tongue area were calculated.
Results: The positional changes of the tip of the tongue were concordant with the positional changes of the lower incisor, elevation of the dorsum of the tongue and stoopness of the base of the tongue occured in the retrusion group. Tongue area increased in both groups.
Conclusion: The tip of the tongue followed the movement of the lower incisor altered with fixed appliance therapy in sagittal direction. In cases where upper incisor retraction is planned, tongue tip should be expected to adapt by rising vertically.
Keywords: incisors, fixed appliance therapy, cephalometric tongue position, Rakosi tongue analysis, tongue area.

Published: December 2024

Objective: This in vitro study aimed to evaluate the scan accuracy of 6 intraoral scanners (IOSs) by using a dentate model.
Methods: A maxillary dentate reference model was digitized with an industrial-grade blue light optical scanner to generate a reference standard tessellation language (STL) file. The same model was digitized by using 6 IOSs (Trios 4, Trios 3, Primescan, Omnicam, Planmeca Emerald S, and Medit i700) (n=10) to generate test scan STLs. All STL files were imported into a 3-dimensional analysis software program (Geomagic Control X). Test scan STLs were superimposed over the reference STL by using the initial and best-fit alignments of the software program, and the deviations of the scans of IOS from that of the optical scanner were calculated with the root mean square (RMS) method. The average deviation method was used to define the precision of the scans. Kruskal-Wallis and Bonferroni tests were used to statistically evaluate the data (α=0.05).
Results: A significant difference was observed between groups in terms of RMS values (p
Comparative Analysis of Data Efficiency Between Conventional Periapical Radiography and Digital Subtraction Radiography in Chronic Periodontitis Patients
Authors: Alan Arzu , Tözüm Tolga , Kansu Hilmi
Published: December 2024

Purpose: Advancements in technology have driven a shift towards digital techniques alongside conventional screening methods in
dental radiology and across medical disciplines. This study aims to compare the efficacy of two radiographic techniques, periapical
radiography and digital subtraction radiography, in assessing bone recovery processes.
Materials and Methods: Sixty mandibular premolar and molar regions in eighteen chronic periodontitis patients undergoing flap
surgery were examined pre- and post-operatively using both periapical radiographs and digital subtraction radiography.
Periodontal surgery outcomes were monitored by recording periodontal index, pocket depth, and gingival recession preoperatively
(baseline) and at the 3rd and 6th months postoperatively. Standardized parallel periapical radiographs and via digital subtraction
radiography images were analyzed by different observers to evaluate changes in alveolar bones and assess surgical outcomes.
Results: Results showed significant reductions in index values and pocket depths, along with an increase in gingival recession.
Intraobserver consistency was found to be good and fair, while interobserver consistency was poor across the 0-3, 3-6, and 0-6
month periods. Radiographic evaluation demonstrated a statistically significant increase in digital subtraction radiography data
compared to conventional radiography in defect recovery throughout the follow-up period.
Conclusions: This study demonstrated that the digital subtraction radiography technique is more efficient in detecting minimal
changes in mineralised tissues that cannot be clearly traced by conventional radiographic techniques.

Authors: Şahin Tuğba
Published: December 2024

Purpose: Gingival recession is a commonly reported symptom following orthodontic treatment, for which identification is crucial to therapeutic management. The aims of this study were to determine the frequency of recession occurring after orthodontic treatment, assess the gingival phenotype in patients with recession, and investigate the various types of recession.
Materials and Methods: This study involved 80 patients aged 18-65 years who had completed fixed orthodontic treatment, and they were categorized into two groups based on the presence of gingival recession. Periodontal indices were obtained for all patients. Patients with gingival recession had assessments taken for gingival recession depth, gingival recession width, gingival tissue thickness, and keratinized gingival width. Statistical analyses were performed with a significance level of p<0.05 to compare participants with and without gingival recession.
Results: Patients with gingival recession exhibited significantly lower rates of gingivitis than those without gingival recession. Tooth number 31 exhibited the highest incidence of gingival recession, at 31.2%. Gingival recession was observed in 93.5% of Cairo Class 1 patients. Among the participants, 51.9% had a thin gingival phenotype, while 48.1% had a thick phenotype.
Conclusion: To minimize the risk of gingival recession and maintain periodontal health, the study highlights the need for careful evaluation and preventive actions throughout and following orthodontic treatment.
Three-Year Outcomes of Combined Autotransplantation and Regenerative Endodontic Treatment of an Immature Tooth: A Case Report
Authors: Özden İdil , Canbazoğlu Emrah , Sazak Öveçoğlu Hesna
Published: December 2024

Autotransplantation and regenerative endodontic treatment are biologically based dental treatment modalities.
Autotransplantation may be a more affordable alternative to implants for patients who experience tooth loss at a young age.
Regenerative endodontic treatment is also an alternative to routine endodontic treatment as it can allow the regeneration of
necrotic or inflamed pulp tissue. The aim of this case is to report a successful 3-year treatment outcome in an immature tooth
using a combination of autotransplantation and regenerative endodontic treatment. An 18-year-old female patient with
complaints of severe pain and mobility at 37. The patient’s medical history revealed no systemic disease. Clinical and radiographic
examination revealed that 37 had undergone root canal treatment 3 years ago. Retreatment of the root canal was initiated, but the
symptoms did not improve despite interm treatment. After surgical consultation, it was decided to extract 37. For
autotransplantation, 38 was extracted atraumatically and autotransplanted into the socket of 37 and splinted for 2 weeks.
Regenerative endodontic treatment was planned due to the radiolucency observed in the periapical area of the tooth at the
6-month follow-up. Regenerative endodontic treatment was performed on the autotransplanted tooth using platelet-rich fibrin
obtained from the patient’s own blood. The tooth remained asymptomatic and functional for 3 years. Root development continued
and periapical healing was complete at 6 months. The tooth showed a positive response to pulp sensitivity tests at the 1-year
follow-up. The combination of autotransplantation and regenerative endodontic treatment can be considered as a long-term
treatment option for immature teeth.

The Lapindo mudflow disaster at the PT Lapindo Brantas drilling site in Ronokenongo Village, Porong District, Sidoarjo Regency, East Java caused the loss of agricultural and residential areas. The research aimed to detect the areas that are affected by Lapindo mudflow 2006-2022 using Landsat 7 ETM and Landsat 8 OLI-TIRS imageries, as well as visualize their impact using the cloud computing-based Google Earth Engine/GEE platform. Spatiotemporal data analysis was performed on the GEE platform using random forest machine learning as algorithm for supervised land use classification, while visualization was carried out through Earth Engine Apps. The results showed an increase in the mudflow-affected area from 2006 (204.57 ha) to 2012 (542.32 ha) with northeast direction, whereas the increase was insignificant at the following years. Within the detection period, agricultural land was the most affected area, followed by residential areas and bare land. The area ordering was similar during all detected years. The increasing size of the affected area can potentially have both direct and indirect impacts on the surrounding area. Therefore, special action is needed for the surrounding area, such as relocating settlements to safer areas against the Lapindo mudflow disaster.
Museum Rhetoric as Nation-Building
Authors: Sorensen Amanda H
Published: December 2024

This paper examines analog records, ledger book pages and catalog cards, at the Smithsonian Institution (SI) National Museum of Natural History within the anthropology collections, examining how these documents advance an information infrastructure categorizing the Pacific Northwest materials making up accession 000051. Within this case study and textual analysis, I found that using a nation-building lens elucidated knowledge organization (KO) logics at play with these records. My critical reading outlines the ways these records firmly place Indigenous materials and belongings under SI and broader Euro-American knowledge systems via language use and place names, rhetorically furthering land dispossession and functioning to realize the US as a nation. This paper positions KO and associated rhetoric and language use as a tool of nation building, and museum records as a process, a genre of writing that have been honed, remade, and reinscribed over time within institutions toward political and national ends. I end this paper describing ongoing projects supporting and furthering Indigenous sovereignty via KO work in relation to cultural heritage collections, illustrating responses to the nation-building rhetoric within the SI records I analyze.
Vers un modèle de maturité pour la gestion documentaire augmentée dans les organisations contemporaines: composantes et stratégie de mise en oeuvre
Authors: Alaoui Siham
Published: December 2024

Au cours des dernières années, on observe un intérêt croissant envers l’automatisation des pratiques de gestion documentaire, grâce à la mise à profit des outils d’intelligence artificielle (IA), en parlant notamment d’une gestion documentaire augmentée. Cependant, l’intégration effective et efficace de l’IA aux processus archivistiques commande l’existence d’un ensemble de requis informationnels, technologiques, managériaux et normatifs. Cela ferait en sorte que les organisations puissent s’emparer du potentiel de l’automatisation pour soutenir leur devoir de transparence et améliorer leur performance. Le but de cet article est de proposer un modèle de maturité de six niveaux, mettant de l’avant les requis du déploiement de la gestion documentaire augmentée, de même que les pratiques et les dispositifs nécessaires à leur opérationnalisation. Il est aussi question d’identifier les aspects organisationnels à prendre en considération pour favoriser la transition d’un niveau de maturité à un autre.

The monitoring of karst spring release regimes is becoming more and more relevant due to the fact that karst waters are of exceptional quality and most often it is only necessary to chlorinate these waters in order to use them for water supply. In addition to monitoring the discharge regime, it is certainly necessary to establish monitoring of quality parameters that are generally observed sporadically (seasonally or monthly). An example of a well-designed monitoring of quantitative and qualitative parameters is Banja spring (western Serbia). The paper presents the analysis of time series pH values, electrical conductivity, turbidity, suspended sediment, total number of bacteria (TNB), discharge (D) and precipitation (P) using autocorrelation and cross-correlation analyses.
