Diabetes mellitus is a major health challenge around the world. The blood glucose level is one of the major factors in the human body and a significant increase in its level can cause many harmful effects in human life. It is expected that early diagnosis of diabetes mellitus can lead to rapid and effective treatment of glycemic control. As the number of people who suffer from diabetes mellitus increases significantly, a study on diabetes mellitus prediction was done through well-known methods in data mining (DM). In this paper, a genetic algorithm (GA)-based suppressor mutation (SM) optimisation rule miner has been proposed as a cooperative approach for prediction of diabetes mellitus. A novel fitness function has been incorporated into the GA-SM approach to generate a comprehensive optimal rule set while balancing accuracy, sensitivity and specificity. The proposed rule miner was compared against three rule-based algorithms, namely CN2, J48 and BF tree on the Pima Indians Diabetes Dataset with 768 patient records using ten-fold cross validation. The results obtained prove that the proposed GA-SM approach has outperformed CN2, J48 and BF tree with respect to accuracy and kappa.

Wireless sensor networks involve a massive number of sensor nodes often deployed to observe the physical world. Energy efficiency is the challenging issue in the design of WSN. For attaining energy efficient characteristic, clustering techniques has been employed. But, it suffers from hot spot issue which defines that the cluster heads (CHs) closet to base station are burdened with more traffic compared to CHs located far away from BS due to multihop communication. To resolving this, we present a social spider-based unequal clustering protocol (SSUCP) for WSN. SSUCP is based on the nature of social spiders to select the proper CHs and cluster size. Based on the fitness functions and node parameters, the interested decision of selecting the proper CHs and cluster size were made. The SSUCP is implemented in MATLAB and an extensive experimentation takes place under three situations based on distance to BS for ensuring the consistent results of the proposed method. In addition, the SSUCP is validated in terms of energy efficiency and network lifetime analysis. The attained experimental outcome verified that the SSUCP is the superior one over the compared methods.

Over the years, health informatics and eHealth gained more popularity in health care application. The collection of eHealth data becomes easier due to the advancement of digital technology. In this paper, the e-Health based supporting system is developed for the classification of a retinal disease called CNV. CNV is a retinal disease caused due to the growth of abnormal blood vessels in the choroidal layer. A good classifier for CNV data makes the process of identifying the disease easier and it will help the medical practitioners to give the treatment at the right time. A comparison has been done among different machine learning classifiers such as support vector machine (SVM), k-nearest neighbours (kNN), neural network (NN), ensemble and naive Bayes classifiers and they are tested and evaluated based on accuracy and training time. From the results, it is observed that kNN classifier outperforms the other classifiers in all aspects.

Hibiscus plant (Hibiscus rosa-sinensis L.) contains several antibacterial compounds such as tannin, alkaloids, triterpenoids, cyanidine, glycosides, and quercetin. One alternative to deal with diseases such as caries caused by bacterial infections is the use of hibiscus (Hibiscus rosa-sinensis L.). This study was aimed to determine the inhibitory effect of hibiscus flower extract on the growth of Streptococcus mutans bacteria causing caries. This was an experimental study with the modified Kirby-Bauer method using disks. Hibiscus flowers were obtained from Kotamobagu, North Sulawesi, and extracted by using maceration method and 96% ethanol as the solvent. The results showed that the total inhibition zone diameter resulted by hibiscus flower extract in five Petri dishes was 23.5 mm with an average of 4.6 mm. In conclusion, hibiscus flower extract had a weak inhibitory effect on the growth of Streptococcus mutans.

Abstract: Third molar development is a concern in dental care because of its influence on stomatognathic system. Due to third molar irregular pattern of eruption, different clinical and radiographic considerations on how to decide an extraction were studied. This study was aimed to evaluate the effect of mandibular third molar mesial angulation (MA) towards the extractions on panoramic radiographs. This was a retrospective study. A longitudinal study of mandibular third molars (n=192) of 102 individuals (50 Female and 52 Male) was conducted. Development of the mandibular third molar was staged according to modified Köhler et al. staging technique. Mesial angulation was measured from the intersection between axes of third molar and adjacent second molar of the most developed stage for extraction cases or before root completion for non-extraction cases. Of 102 subjects, 107 mandibular third molars were extracted. The increase of 1° of MA would increase the odds ratio (OR) of extraction by 1.113 (95% CI 1.070-1.158, p<0.01). The ROC curve showed the MA of 18.5o as the threshold of extraction with 76% of sensitivity and 68% of specificity. In conclusion, MA has the possibility as a predictive factor of mandibular third molar extraction. Future studies using bigger sample sizes and variations of third molar development are suggestedKeywords: third molar, angulation, extraction, predictive factor, panoramic radiographs Abstrak: Pertumbuhan molar ketiga menjadi perhatian pada perawatan dental karena pengaruh-nya pada sistem stomatognasi. Terdapat banyak penelitian tentang berbagai pertimbangan klinis dan radiografis untuk melakukan ekstraksi molar ketiga karena pola erupsinya yang tidak menentu. Penelitian ini bertujuan untuk mengevaluasi efek angulasi mesial (AM) dari molar ketiga rahang bawah terhadap tindakan ekstraksi pada radiografi panoramik. Jenis penelitian ialah retrospektif. Pengamatan molar ketiga rahang bawah (n=192) secara longitudinal dilakukan pada 102 individu (50 perempuan dan 52 laki-laki). Pertumbuhan molar ketiga diukur berdasarkan tahap pertumbuhan dari teknik modifikasi Köhler et al. AM diukur dari pertemuan aksis molar ketiga dan molar kedua di sebelahnya, pada tahap pertumbuhan paling akhir pada kasus ekstraksi, atau sebelum akar gigi terbentuk sempurna pada kasus non-ekstraksi. Pada sampel penelitian, ekstraksi dilakukan pada 104 molar ketiga rahang bawah. Peningkatan 1o dari AM akan meningkatkan rasio peluang dari ekstraksi sebesar 1,113 (95% CI 1,070-1,158, p<0,01). Pada kurva ROC, AM sebesar 18,5o menunjukan 76% sensitivitas dan 68% spesifisitas. Simpulan penelitian ini ialah AM dapat digunakan sebagai faktor prediksi terhadap ekstraksi molar ketiga rahang bawah. Perkembangan penelitian selajutnya dapat dilakukan dengan jumlah sampel yang lebih besar dan dengan memperhatikan pertimbahan klinis serta parameter radiografik lainnya.Kata kunci: molar ketiga, angulasi, ekstraksi, faktor prediksi, radiografi panoramik

Due to third molar irregular pattern of eruption, different clinical and radiographic considerations on how to decide an extraction were studied. This study was aimed to evaluate the effect of mandibular third molar mesial angulation (MA) towards the extractions on panoramic radiographs. This was a retrospective study. A longitudinal study of mandibular third molars (n=192) of 102 individuals (50 Female and 52 Male) was conducted. Development of the mandibular third molar was staged according to modified Köhler et al. staging technique. Mesial angulation was measured from the intersection between axes of third molar and adjacent second molar of the most developed stage for extraction cases or before root completion for non-extraction cases. Of 102 subjects, 107 mandibular third molars were extracted. The increase of 1° of MA would increase the odds ratio (OR) of extraction by 1.113 (95% CI 1.070-1.158, p<0.01). The ROC curve showed the MA of 18.5o as the threshold of extraction with 76% of sensitivity and 68% of specificity. In conclusion, MA has the possibility as a predictive factor of mandibular third molar extraction.

Abstract: Mercury is a very toxic compound to humans, therefore, a method to overcome its presence in the environment is required. Detoxification of mercury can be done by using mercury resistant bacteria. Mercury-resistant bacteria Bacillus cereus isolate FUA have been obtained from the urine of patients with dental mercury amalgam. This study was aimed to determine the mercury detoxification activity of Bacillus cereus isolate FUA at varying pH medium and incubation temperature. The study was carried out by growing Bacillus cereus isolate FUA on oblique media, then were planted in the growth media of LB broth containing mercury compounds of 10 ppm HgCl2 with varying pHs of 5, 7, and 9 and incubation temperatures of 15, 25 and 35oC. The amount of bacterial growth was analyzed by using spectrophotometer and mercury levels were analyzed by using CV-AAS method. The results showed that the growth and mercury reducing activity of Bacillus cereus isolate FUA were optimum at pH 7 and incubation temperature of 35oC. In conclusion, the growth of Bacillus cereus isolate FUA and its mercury reducing activity were optimum at pH 7 and temperature of 35oC. It is expected that the results of this study can be the basis for further research on the process of mercury detoxificationKeywords: Bacillus cereus, urine, mercury resistance, pH, temperature Abstrak: Merkuri adalah senyawa yang sangat beracun bagi manusia sehingga diperlukan metode untuk mengatasi keberadaannya di lingkungan.
