Betonarme perdelerde enerji sönümleme kapasitesinin meta-modelleme yöntemleriyle incelenmesi
Authors: DEĞER Zeynep , TAŞKIN KAYA Gülşen , SÜTCÜ Fatih
Published: April 2023

Son yıllarda çok sayıda araştırmaya konu olan depreme dayanıklı yapı tasarımı yöntemlerinden biri enerji esaslı yapı tasarımı yöntemidir. Bu yöntem, deprem sebebiyle binaya etki eden enerji talebinin yapıdaki çeşitli dinamik mekanizmalar tarafından sönümlenmesi esasına dayanır. Depremin enerji talebinin bilinmesi halinde, yapısal elemanların ayrı ayrı ve toplam enerji sönümleme davranışlarının isabetli bir şekilde elde edilmesi doğru bir tasarım yapılması için esastır. Depreme dayanıklı yapı tasarımında yüksek rijitlik ve dayanım sağladıkları için yaygın olarak kullanılan betonarme perde duvarlarının, deprem etkisi altında doğrusal olmayan davranışı, yüksek deformasyon seviyelerinde rijitliğin azalması ve enerji sönümleme kapasitesinin artması şeklindedir. Perdelerin doğrusal olmayan davranışı, enerji yönünden düşünüldüğünde çevrimsel enerji sönümleme kapasitesi ile ele alınabilir. Literatürde betonarme perdeler için enerji karakteristiklerini belirlemeye yönelik çalışmalar sınırlı olup, mevcut deprem yönetmeliklerinde enerji esaslı tasarıma henüz yer verilmemektedir. Bu çalışmada, dünya çapında yapılmış çevrimsel yüklemeli perde duvar deneylerini içeren geniş kapsamlı bir veri tabanı oluşturulmuş ve çeşitli perde parametrelerinin (geometri, donatı oranları, eksenel yük, yükleme şekli vb.) enerji sönümleme davranışı üzerindeki etkileri incelenmiştir. Ayrıca, meta-modelleme yöntemleri kullanılarak enerji sönümleme davranışının kestirilmesine yönelik bağıntılar geliştirilmiş; meta-modelleme tekniği olarak oldukça başarılı bir yöntem olan ve analitik bir fonksiyon üretebilen Yüksek Boyutlu Model Gösterilimi (YBMG) yöntemi kullanılmıştır. Önerilen YBMG tabanlı tahmin modeli, aynı anda hem yüksek doğruluklu (R2 = 0.93, tahmini/gerçek değer oranı = 0.99) hem de transparan (kapalı kutu olmayan) bir model olması yönleriyle ön plana çıkmaktadır. Tasarım açısından bakıldığında, enerji sönümleme kapasitesi gerçeğe yakın bir şekilde kestirildiğinde, perde tasarımı sırasında farklı detaylandırma seçeneklerinin sönümlenen enerji açısından değerlendirilmesi anlamında değerli olacaktır. Mevcut binaların değerlendirilmesi ve hasar analizi açısından ise, çalışma sonuçları sönümlenen enerjiyle yakından ilişkili olan yapısal hasar konusunda bilgi verecektir.

Authors: YEL İbrahim , BAYSAL Mehmet
Published: April 2023

Yazılım geliştirme projelerinin yönetilmesi, karmaşık iş adımlarını içermesi ve kullanılan kaynakların gerçek kişilerden oluşması nedeniyle zordur. Projenin kendi özellikleri ile birlikte organizasyonel değişkenler ve geliştirici ekibin yetkinlikleri, projenin başarısını doğrudan etkileyecek faktörler arasındadır. Yazılım geliştirme süreç yöntem seçimi probleminin çözümünde bu üç faktörün kullanılması ile yazılım geliştirme projelerinin başarısının artacağı düşünülmektedir. Yazılım projelerinin yönetiminde "Çevik ve Şelale (Geleneksel) Yöntemler" dâhil olmak üzere farklı süreç yöntemleri kullanılmaktadır. Geliştirme ekiplerinin yeteneklerine göre projelere atanması ve projelerin kendi aralarında sıralanması önemli bir noktadır. Bu çalışmada ilk adım olarak, bulanık AHP metodu kullanılarak kriterlerin ağırlıkları belirlenmiştir. Daha sonra projelerin ve çalışanların sıralanmasında bulanık WASPAS, bulanık EDAS ve Aralık Değerli Nötrosofik Z Sayıları (NZN) yöntemleri kullanılmıştır. Bu araştırmanın sonuçlarına göre, yazılım geliştirme yöntemi kararının uygulanması halinde hata sayısı ve çözümlerinin kişi-gün değerleri gerçek değerler ile kıyaslandığında %4-%6, %6-%8 ve %6-%8,7 oranında iyileştirilebileceği tespit edilmiştir.

A single guide to impregnate samples with Golgi-Cox solution within 24hr and represent results with a set of algorithm v1
Authors: Roy Avishek
Published: April 2023

Golgi-Cox staining is one of the old but relevant histological technique to identify neurons in superficial/ deep brain structures. The goal of this staining is to accurately perform morphometric analysis on the desired neurons in health and diseases. Due to the origin of its own there are different variations of the protocol itself. Majority of them take at least one to two week to have impregnation of the stain into the tissue/ cells. This is due to the physical property of the stain and lipophilic nature of the central nervous system. Therefore to enhance the diffusion of the stain into the brain samples, we have came up with a modification of only one protocol out there by Ranjan and his colleagues. Where we have decreased the thickness of the brain sample to 5μm from 25±1μm (for rat brain) and incubated the sample with Golgi-Cox solution at 37°C in order to reduce the path of travelling and simultaneously help the diffusion process at physiological temperature. The results showed a significant amount of impregnation of the Golgi-Cox solution into deep brain structures viz. hypothalamus, hippocampus within a timespan of 24 hour. This reduces the labour, time and enhance the efficiency of the impregnation process enabling a better image to analyse further. The overall goal of this protocol is to help experimenter focusing on the analysis of the morphometric data as well as complementing it with other relevant functional data by reducing the time to stain samples enhancing efficacy. Finally, we hope that this modified protocol will not only help researchers in field of neuroscience to perform the technique with ease but also help them to represent their result in the best/ unique way using different algorithm and softwares mentioned in the protocol.

This paper presents some of the earlier studies pertaining of analytical methods for tolerance, its effect and applications in the automotive industry. In today's automotive and aerospace industries, the tolerance process is crucial in the design phase and product development. In the design process, issues such as matches and limits, geometric and tolerance dimensions (GD & T) should be considered by designers to assist manufacturers and installation operators to reduce the cause of failure of critical parts. The impact of failure can destroy some critical parts and reduce the system performance. It is also noted that automotive suppliers for part and components face problems related to the quality due to miscommunication related to tolerance. Quality improvements with various methods have been made by automotive suppliers for part and components to remain competitive and building long-term relationships with automotive manufacturers. Automotive parts suppliers are required to contribute towards improving the overall quality of the car. While empirical studies show that statistical concepts are essential for good and important quality management in tackling the manufacturing process, there is insufficient emphasis on the use of tolerance in quality practices among these suppliers. The impact on manufacturing costs and the methods used will be reviewed as a benchmark for further research to optimize and improve the component reliability. As a result, it can be ascertained that extensive researches have been carried out worldwide focusing on tolerance optimization method for mechanical components in the automotive industry.
«SECONDARY SOURCES» OF CELTIC AND NORSE MODES IN MODERN POPULAR CULTURE THROUGH THE PRISM OF FANTASY
Authors:   Taras Shevchenko national University of Kyiv, Pilkevych Andrii
Published: April 2023

The article deals with the main sources of the modern fantasy genre, presented in the form of several blocks of borrowings. First of all, this is the influence of the figures of the «Celtic Revival», who were engaged the search, recording and systematization of mainly Irish, Scottish and Welsh tales, myths and a wide range of folklore material. This legacy was transformed into an original literary tradition characterized by a combination of legendary heritage with fictional art elements and authorial reworking. Examples of pseudo-translations from Celtic languages presented as authentic, such as the work of James Macpherson. The article identifies the key figures of the «Celtic Revival» and singles out their works, which, in the opinion of the author, had the greatest impact on the formation of the fantasy genre. In particular William Butler Yeats, Isabella Augusta Persse (usually Lady Gregory), Thomas Moore, Edward John Moreton Plunkett (usually Lord Dunsany), Irish writer, poet, painter – George Russell, Irish playwright, poet, writer, collector of folklore – John Millington Synge, Irish writer Alice Letitia Milligan. The Romantic Age in English literature had a significant impact on the fantasy genre. The author analyzed the most relevant creative developments in this connection: William Blake, John Keats, William Wordsworth, Percy Shelley, Samuel Taylor Coleridge, Robert Southey, Walter Scott, Mary Shelley. Gothic fiction and in particular Gothic novels, is an equally important «factor of influence». First of all, it is about Horace Walpole, Clara Reeve, William Beckford, Matthew Gregory Lewis, Ann Radcliffe, Bram Stoker. The author presents a vision of the «wide treasury of inspiration» opus of the main archetypes of European fantasy, which also includes «German Romanticism». It is represented Ludwig von Arnim, Ernst Hoffmann, Ludwig Uhland, Friedrich von Hardenberg (usually Novalis), Ludwig Tieck, Joseph von Eichendorff.

Source parameters and tectonic setting of the 1990 Lee Vining, California, earthquake sequence
Authors: Horton Stephen P. , dePolo Diane M. , Walter William R.
Published: April 2023

On 24 October 1990, a magnitude 5.0 (Md) earthquake occurred near Lee Vining, California. It was a strike-slip event with a hypocenter 5 km east and 11.5 km below the surface trace of the Sierran frontal fault, which at this locality has 21 m of Holocene vertical offset. A time-domain deconvolution technique was used to estimate the source-time function of this event using a small foreshock as an empirical Green's function. The resulting source-time function indicates a simple rupture process. The moment for this event is 3.0 × 1023 dyne-cm, and the static stress drop is 36 bars.

Moderate-sized earthquakes occurring in the western Basin and Range since 1978 have been concentrated in the central part of the Walker Lane Belt. This is an area of diverse topography and numerous strike-slip faults that lies between the Sierra Nevada Mountains on the west and typical Basin and Range topography on the east. Most of these earthquakes have strike-slip focal mechanisms, and with the exception of earthquakes in the Long Valley Caldera area, they are consistent with left-lateral slip on faults that trend northeast and right-lateral slip on faults that trend northwest.

Authors: Fabikantov O. L. , Osmanov R. E. , Popova E. V.
Published: April 2023

Cataract in patients of older age groups is one of the reasons for the deterioration of geriatric status, the manifestations of which are geriatric syndromes, but insufficient attention paid to the study of the latter.

Purpose. To study the prevalence of geriatric syndromes among patients with UC, depending on visual acuity without correction.

Patients and methods. Geriatric syndromes were studied in 220 elderly patients with UC, in 240 elderly patients with FC and 200 elderly patients without UC based on methods of complex geriatric assessment. The following geriatric syndromes were analyzed: sarcopenia, hypomobility, malnourishment, pain syndrome, and disorders of general motor activity, psychological problems, cognitive disorders, anxiety-depressive status, sleep disorders and urination.

Results. It was found that the deterioration of visual acuity without correction of less than 0.3 is accompanied by an increase in the majority of geriatric syndromes in elderly and senile patients with UC and especially in 75–89 years of hypomobility syndrome to 93.2 ± 2.5 cases of cognitive impairment to 89.3 ± 3.0 cases, malnutrition to 88.3 ± 3.2 cases and psychological problems to 79.6 ± 4.0 cases per 100 examined, which is significantly higher by 2.0–2.4 times compared to patients of the same age with UC with visual acuity without correction more than 0.3. A decrease in visual acuity of less than 0.3 in patients with UC contributes to an increase in the prevalence and average number of geriatric syndromes in old age to 8.2 ± 1.0 cases versus 3.9 ± 0.8 cases in old age with UC with visual acuity of more than 0.3 (P < 0.001).

Conclusion. The revealed dependence of the prevalence of geriatric syndromes, taking into account visual acuity, indicates the relevance of timely correction.

In an increasingly innovative competitive environment, it is necessary to know the customer in depth and to understand the intrinsic determinants of customer loyalty to the restaurant and brand equity. Culture is a fundamental factor in understanding behaviour, which has often attracted interest because of its moderating rather than determining role. The objective of this research is to examine the determinant role of customers' cultural values (long-term orientation, power distance, and uncertainty avoidance) on the customer's attitudinal process in the restaurant (satisfaction and loyalty) in order to understand how it indirectly affects through the attitudinal process the formation of a restaurant's brand equity. A sample of 540 customers was used, and a SEM model was estimated. The results indicate that cultural values, except for power distance, strongly determine the attitudinal process. Therefore, culture indirectly affects the formation of the restaurant's brand equity.

Published: April 2023

Background: Reliable and early detection of myocardial ischemia using computer-aided analysis of electrocardiograms (ECG) provides an important reference for early diagnosis of CVD. We developed a 12-lead smartphone-based electrocardiogram (ECG) acquisition and monitoring system (called “Spandan”), and an application to assess underlying ischemia from analysis of electrocardiographic (ECG) signals only. Objectives of this study were to validate the Spandan 12 lead ECG interpretation for accuracy in the detection of Ischemia in comparison to cardiologists’ diagnosis and to evaluate the accuracy of ischemia in comparison to the interpretation of standard 12 lead ECG.
Methods: In this multi-center study all patients (n=597) visiting the ECG room at the department of cardiology were enrolled in the study by taking their written consent and explaining the purpose of the study.
Results: Mean age was 52.85 years. The male gender (n=344, 57.62%) shows the maximum frequency than female gender. 12 lead Spandan smartphone ECG recorded fewer false positive cases (8 versus 230) and identified greater true negative cases (310 versus 115). Spandan smartphone ECG recorded better specificity (97.4% versus 33.3%) and positive predictive value (87.4% versus 51.4%) as compared to gold standard ECG. The accuracy of interpretation of Ischemia by cardiologists diagnosis through 12 lead Spandan smartphone ECG was better (100%) as compared gold standard (95.3%).
Conclusions: Our study highlights the potential of Spandan smartphone ECG in the detection of myocardial ischemia. This may improve patient satisfaction and reduce healthcare costs.

A number of different thermomechanical treatments of NiTi have been developed to overcome some of the drawbacks of the traditional NiTi alloy, namely, separation and distortion of instruments. The present study analyzes the data on nickel-titanium instruments and their cyclic fatigue resistance.

Online electronic data base such as PubMed, Cochrane and Google scholar through 31 January 2000 to 31 January 2020 with only English language literature.

Clinical study of 9 article review & stated that the Cyclic Fatigue Resistance Of Nickel Titanium Rotary Instruments tested in artificial blocks or canals ,tested with different NiTi rotary files between 200-500 rpm and accordingly torque under controled/uncntroled temperature in curved canls fracture occure. The findings of this systematic review and meta-analysis point to the possibility that the temperature at which the instruments are tested may affect the results of cyclic fatigue resistance on NiTi files with a different behavior depending on the heat treatment of the alloy and that an increase in the angle of curvature of artificial canals has a detrimental effect on the cyclic fatigue resistance.

Reciprocal movement exhibited the best performance with regard to cyclic fatigue resistance. The thermal treatment of the instrument’s alloy, its cross section, and the glide path seem to influence the cyclic fatigue resistance. The cyclic fatigue resistance of instruments manufactured with the gold heat treatment is not influenced by room or intracanal temperature.

Published: April 2023

To evaluate the occurrence and intensity of post-operative pain & number of analgesic tablets intake after single visit endodontic treatment using three different Bioceramic sealers.

45 single rooted teeth diagnosed with asymptomatic irreversible pulpits requiring endodontic treatment were randomly assigned to three groups (n=15) according to sealer used during obturation. To avoid bias in post-operative pain perception, each sealer is evaluated in three different single rooted teeth of the same patient. The different groups are Group 1-MTA-Fillapex, Group –II Ceraseal RCS, Group-III BioRoot RCS. Single visit Endodontic treatment was performed and teeth were obturated using cold lateral compaction and different root canal sealers with no radiographic material extrusion beyond the apex. Severity of post obturation pain was assessed by Visual Analog Scale (VAS) with score ranging from 0 to 10 at 6hrs, 12hrs, 24hrs and 48hrs intervals. The need for analgesic (Tab. Aceclofenac 100 mg) intake was also recorded. Differences in incidence of postoperative pain were analyzed using the Kruskal Wallis test followed by Mann Whitneys Post Hoc to compare the mean VAS score & number of analgesics taken between three groups at different time intervals (p<0.05).

MTA Fillapex shows statistically significant difference in mean VAS score (more pain) at 6hrs, 12hrs (p value < 0.001) & at 24hrs (p<0.005) than Ceraseal RCS and BioRoot RCS. There is statistically significant difference in the no. of analgesic intake for MTA Fillapex i.e., more tablets taken by the patient to relive pain (p<0.001) as compared to Ceraseal RCS and BioRoot RCS. The decrease in pain was statistically significant for each time intervals from 6hrs to 48hrs for all the three groups.

The teeth of the patients where MTA Fillapex sealer was used as a sealer in the obturation showed significantly more pain at 6hrs & 12hrs and needed to take more analgesics than teeth obturated with other two sealers. This probably could be due to leaching out of resin constituents from MTA Fillapex.

Published: April 2023

Endodontic treatment of Radix Entomolaris is challenging and requires a complete understanding of root canal system, and skills to manage the commonly occurring mishaps during the treatment. Therefore, comprehensive clinical & radiographic interpretation is critical in identifying unusual root canal morphologies. The additional root variation in the mandibular molars may be present either mesio-bucally (Radix Paramolaris) or distolingually (Radix Entomolaris). This case series intends to discuss the diagnosis, endodontic challenges during file separation, and non-surgical endodontic management of two cases of Radix Entomolaris in the mandibular first molar.

Authors: Joshi Gangesh Kumar , Bhattarai Subash Kumar , Bhandari Kishor
Published: April 2023

The supply chain plays a vital role in the successful completion of a construction project. Lack of proper supply chain management in any construction project results in cost overrun, time overrun, claims, disputes, and low productivity, which may ultimately lead to failure of the project. The overall objective of this study is to perform a comparative analysis of the need and importance of supply chain management based on stakeholders' perceptions of the selected building construction projects in Kathmandu valley. A total of thirty-four projects were taken for the study. Among these, 16 projects were executed by DUDBC and NRA, and 18 projects from private developers. The primary data collection tool used for the study was a questionnaire survey based on the Likert scale. A key informant interview along with a desk study was also conducted. The responses of questionnaires were ranked using the Relative Importance Index (RII). The findings were based on the comparison of views of public and private stakeholders on factors influencing the importance, challenges, and solutions of the problems of supply chain management. The findings show that both the public and private stakeholders agree on the high importance of proper supply chain management in the construction industry, but their perceptions differ on factors contributing to and benefits obtained from an efficient supply chain. Additionally, public and private stakeholders have differing opinions on the most pressing challenges facing supply chain management, its efficiency, and material management. Public stakeholders focused more on quality and delayed delivery of materials, while private stakeholders focused more on cost and efficiency issues. On the solutions and approaches for improvement of supply chain management, both the public and private sectors agree that improved integrated management between the supply chain and project site is essential to maintain a reliable and efficient supply chain. However, both stakeholders differ slightly on the approaches needed to improve supply chain management. Finally, the study shows that public and private stakeholders in building construction projects in Kathmandu agree that while major challenges exist in supply chain management, solving these problems through proper integration and communication will lead to an efficient and qualitative supply chain vital for a project's completion.

En esta contribución utilizamos la teoría de Ginzburg-Landau dependiente del tiempo en presencia de corrientes a campo magnético nulo para investigar la dinámica de vórtices cinemáticos en una lámina superconductoras mesoscópicas con un pilar central delgado. Nuestro estudio abarca dos casos: (a) un pilar central al cual variamos su altura, simulada mediante el parámetro T > 1;0, con una interfase superconductor-vacío en toda la muestra, simulada con el parámetro γ = 1;0; (b) un pilar central con una condición de contorno superconductor-superconductor a mayor temperatura crítica Tc, (γ > 1;0); consideramos también una muestra homogénea, es decir sin pilar T= 1;0. Analizamos la influencia de diferentes condiciones de contorno en el estado de vórtice cinemáticos y sus efectos en la respuesta magnética mediante el análisis de las curva corriente-voltaje y resistividad-corriente; también es calculada la velocidad de aniquilación de los pares vórtice-anti vórtice en función de la corriente aplicada para varias condiciones de contorno. Los resultados muestran que las corrientes críticas y la dinámica de la aniquilación de vórtices cinemáticos son altamente dependiente de la altura del pilar y de las condiciones de contorno.

Background: To accelerate the establishment of a genetic improvement system for Onobrychis viciaefolia Scop. by cultivating haploid plants and producing pure parental material. Methods: We endeavored to set up the Onobrychis viciaefolia Scop. anther culture system, examine the suitable anther pre-treatment method and the factors influencing medium type and hormone ratio during anther regeneration. Result: The regenerative capacity of intact anthers was preserved by 48h low temperature (4°C) medium treatment. Or the broken anthers were obtained when the regenerated grass was budding and preserved in the medium after 48 hours of low temperature treatment; callus induction was based on MS and the callus rate was 18.33% when 1.0 mg/L 2,4-D + 0.75 mg/L 6-BA + 0.8 mg/L NAA + 2.0 mg/L KT was added. With N6 as the basic medium, the addition of 2.0 mg/L 2,4-D + 0.75 mg/L 6-BA + 0.4 mg/L NAA + 0.5 mg/L KT resulted in a healing rate of 16.19%; the addition of 0.5 mg/L 6-BA + 1.0 mg/L KT to the MS medium resulted in a differentiation rate of 68%; during the construction of the anther histoponic system, browning and waterlogging of the healing tissues and vitrification of the seedlings hindered the formation of regenerated plants.

Introduction Pole dance is considered a moderate-intensity exercise that improves health, and cardiorespiratory fitness as a combination of dance, sport, and physical recreation. However, due to its physical demand, pole dance may cause potentially severe injuries. According to the literature, 85% of all pole dancers reported injury during training. Aim of the study The aim of the study was to determine the frequency and characteristics of injuries in female pole dance amateurs in Poland. Materials and methods In this prospective survey, case-control research, data was collected from female pole dancers using online questionnaires. The survey was composed of 23 questions, concerning the type of injury, the way of its treatment, complications, and recovery time. The collected data was statistically analyzed. Results 445 females (mean age = 30.8 years, SD = 5.67) were included into the study group. 42.9% of females reported injuries, the most common were contusions (60.2%) and dislocations (19.9%). The shoulder (27.2%) and wrist (12%) were the most frequently affected structures. 80% of injuries required discontinuation in training, whereas 76% of all trauma cases demanded consultation with doctors or physiotherapists. The further analysis stated that risk factors for injury were age (p = 0.0138) and training frequency (p = 0.003). The incidence of injury was also influenced by the duration of practice (p < 0.0001). In 59.7% of cases, injury considerably influenced respondents’ daily activities. Conclusions Pole dance is a demanding sport with a high incidence of injuries, which mostly affect the upper extremities. A higher risk of injury may be determined by increasing age, duration, and frequency of training
I CAN HANDLE IRREPARABLE CUFF TEAR WITH REHABILITATION/I AM SURE THAT YOU CAN’T HANDLE ALL WITH REHAB

Rotator cuff tears (RCT) are one of the most commonly treated orthopaedic pathologies, yet controversy exists regarding the management of these injuries. Irreparable rotator cuff tears are unpredictable with respect to their clinical presentation. The spectrum of pain and functional disability varies widely. Rehabilitation protocol is always the first solution in treating irreparable cuff tears, but non-functional and painful shoulders (e.g., arthrosis) is an indication for surgery. Can we ask ourselves a question: where lies the limit of trying “persistent” surgical repair of massive irreparable RC lesions? There is a lack of high-quality comparative studies to guide treatment recommendations. Physical therapy compared to surgery is associated with a lower improvement in perceived functional outcome and higher clinical failure rate. However, there is insufficient evidence to establish an evidence-based treatment algorithm for MRCTs. Treatment is based on patient factors and associated pathology and includes personal experience and data from case series. It has to be underlined that the winner is always team physiotherapist/surgeon, and their cooperation is crucial at all stages of therapy

ABSTRACTBackground: South Kalimantan is one of the provinces in Indonesia that occupies the highest second of dental and oral health problems. One of the dental and oral health problems that often faced in school age group is malocclusion that is 15,6%. Malocclusion is an occlusion condition that is not right or an occlusion that deviates from normal condition. The said condition can be happened because tooth shape abnormalities and jaw size. The crowded tooth position can cause caries occurrence, because the overlapped tooth position can complicate in the process of tooth brushing. The food remains that accumulated formed plaque retention and if it’s left alone continually, it will form a cavity in the tooth, causing email demineralization called caries. Purpose: To find out the correlation between malocclusion severity levels and caries status of 12-14 years old students in SMPN 5 Marabahan Material and Methods: This research was an analytic observational with cross sectional approach. The respondents were 12-14 years old students in SMPN 5 Marabahan that were taken with simple random sampling method. The respondents were 47 people. Results: The malocclusion severity level on mild category was 24 people (51%) and the caries status on moderate category was 19 people (40%). The result of Spearman test is p=0,000 < 0,05. Conclusion: There is a correlation between malocclusion severity level and caries status of 12-14 years old students in SMPN 5 Marabahan.Keywords : Caries status, DMF-T Index, Index (MAL I),Malocclusion severity

ABSTRACTBackground: The majority of tooth decay is caused by improper brushing behavior. The correct behavior for tooth brushing refers to the Federation Dentaire Internationale (FDI), including the behaviour of tooth brushing every day at least twice a day, after breakfast and before going to bed at night. The results of RISKESDAS in 2018 reported that only 4.96% of adolescents aged 10-14 years who brushed their teeth properly in the city of Banjarbaru. WhatsApp groups as a media for health promotion is considered as an effective strategy to disseminate information to improve one's knowledge and behavior towards a better outcome. Purpose: To analyze the effectiveness of WhatsApp as a health promotion medium in improving the behavior of brushing teeth properly based on the Federation Dentaire Internationale (FDI) in grade VII students at SMPN 2 Banjarbaru. Material and Methods: This study used a pre-experiment design with one group post test pre test design with simple random sampling technique. The research was conducted at SMPN 2 Banjarbaru with a sample of 173 respondents. Results: The results of the pre test measurement showed that there no respondents in the bad behavior category (0%), 45 respondents (26%) in the moderate category and 128 respondents (74%) in the good category. The result of post test measurement revealed that there were no respondent in bad and moderate category that 173 respondents were fell into good behaviour category. The results of the Wilcoxon comparison test obtained a significance value of 0.000 <0.05, meaning that there was a difference in behavior between before and after being given health promotion. Conclusion: Counseling using WhatsApp social media is effective in increasing the behavior of proper toot brushing according to FDI.Keywords: Health promotion, Proper brushing behavior, Whatsapp
