Abstract Background Neuroprosthetic devices controlled by persons with standard limb amputation often lack the dexterity of the physiological limb due to limitations of both the user’s ability to output accurate control signals and the control system’s ability to formulate dynamic trajectories from those signals. To restore full limb functionality to persons with amputation, it is necessary to first deduce and quantify the motor performance of the missing limbs, then meet these performance requirements through direct, volitional control of neuroprosthetic devices. Methods We develop a neuromuscular modeling and optimization paradigm for the agonist-antagonist myoneural interface, a novel tissue architecture and neural interface for the control of myoelectric prostheses, that enables it to generate virtual joint trajectories coordinated with an intact biological joint at full physiologically-relevant movement bandwidth. In this investigation, a baseline of performance is first established in a population of non-amputee control subjects ($$n = 8$$ n = 8 ). Then, a neuromuscular modeling and optimization technique is advanced that allows unilateral AMI amputation subjects ($$n = 5$$ n = 5 ) and standard amputation subjects ($$n = 4$$ n = 4 ) to generate virtual subtalar prosthetic joint kinematics using measured surface electromyography (sEMG) signals generated by musculature within the affected leg residuum. Results Using their optimized neuromuscular subtalar models under blindfolded conditions with only proprioceptive feedback, AMI amputation subjects demonstrate bilateral subtalar coordination accuracy not significantly different from that of the non-amputee control group (Kolmogorov-Smirnov test, $$P \ge 0.052$$ P ≥ 0.052 ) while standard amputation subjects demonstrate significantly poorer performance (Kolmogorov-Smirnov test, $$P < 0.001$$ P < 0.001 ). Conclusions These results suggest that the absence of an intact biological joint does not necessarily remove the ability to produce neurophysical signals with sufficient information to reconstruct physiological movements. Further, the seamless manner in which virtual and intact biological joints are shown to coordinate reinforces the theory that desired movement trajectories are mentally formulated in an abstract task space which does not depend on physical limb configurations.

A serious environmental problem has occurred due to the negative impact of household waste. Lack of knowledge and awareness of waste processing must be improved through an effective counseling method provided for housewives. The aim of this research was to determine different counseling methods about garbage toward housewives’ knowledge about processing of the household waste. This research carried out on Kampung Pulo, Jakarta Timur on April 2013. A quasi-experiment method with a randomized control group pretest-posttest design was used. Counseling methods of demonstration and movie display were given in two different groups as the treatment. Instrument of knowledge test was used to collect data. The normality testing of Kolmogorov-Smirnov test and the Homogeneity testing of F-test at α = 0.05 resulted a normal distribution and homogenous data. The hypothesis testing of t-test showed t count > t table on 3.34 > 2.03 which rejected the H0, meaning that different knowledge level about processing of the household waste obtained from different method of counseling. It is concluded that, demonstration method was more effective than movie display to increase the housewives’ knowledge about processing of the household waste.

AbstrakTHIS ARTICLE IS RETRACTED DUE TO REDUNDANT PUBLICATION. Berdasarkan penelitian terbaru, olahraga/ latihan mempunyai efek yang signifikan dalam menurunkan glukosa darah penelitian ini bertujuan untuk mengidentifikasi efek dari model latihan isometrik terhadap kadar glukosa darah pada mencit yang dikondisikan mengalami diabetes mellitus. Penelitian ini adalah penelitian eksperimen murni (True Experiment). Menggunakan rancangan eksperimen The Randomise Post Test Only Control Group Design. Sampel adalah mencit jantan dengan berat 20-27 gram. 27 ekor mencit jantan dibagi menjadi tiga kelompok yaitu kelompok control terdiri dari mencit normal yang diinjeksi NaCl sebagai placebo. Kelompok kedua adalah mencit diabetes yang tidak diberikan latihan isometrik dan kelompok ketiga adalah mencit diabetes diberikan latihan isometrik. Kelompok kedua dan ketiga diinjeksi streptozotocin (STZ) untuk meginduksi DM. Setelah 48 jam diinjeksi, kedua kelompok diberikan glukosa oral (Dextrose-40%). Kelompok ketiga diberikan latihan isometrik menggunakan treadmill selama 23.31 menit dengan kecepatan 21 cm/detik dan sudut elevasi 0°. Data dianalisa menggunakan One Kolmogorov-Smirnov test, ANOVA test dan Least Significance Difference (LSD) dengan α<0.05. Analisa One Kolmogorov-Smirnov test p=0.94 pada kelompok kontrol, p=0.50 pada kelompok mencit diabetes, and p=0.19 pada kelompok perlakuan. Hasil ANOVA tes adalah p=0.08. Hasil LSD untuk gluksa darah adalah p=0.23 untuk kelompok perlakuan. Hal ini mungkin terjadi karena pada kelompok kedua terdapat 2 mencit dengan glukosa darah normal dan pada kelompok ketiga kadar glukosa darah awal tidak diketahui. Sehingga, mungkin saja kelompok tersebut juga memiliki kadar glukosa darah normal. Dapat disimpulkan bahwa tidak ada efek latihan isometrik dalam menurunkan kadar glukosa darah. Penelitian selanjutnya disarankan mengidentifikasi lebih jauh tentang frekuensi dan intensitas latihan isometrik yang dapat mempengaruhi penurunan kadar glukosa darah.

AbstractIn this paper, we attempt to answer the questions whether iris recognition task under the influence of diabetes would be more difficult and whether the effects of diabetes and individuals’ age are uncorrelated. We hypothesized that the health condition of volunteers plays an important role in the performance of the iris recognition system. To confirm the obtained results, we reported the distribution of usable area in each subgroup to have a more comprehensive analysis of diabetes effects. There is no conducted study to investigate for which age group (young or old) the diabetes effect is more acute on the biometric results. For this purpose, we created a new database containing 1,906 samples from 509 eyes. We applied the weighted adaptive Hough ellipsopolar transform technique and contrast-adjusted Hough transform for segmentation of iris texture, along with three different encoding algorithms. To test the hypothesis related to physiological aging effect, Welches’s t-test and Kolmogorov–Smirnov test have been used to study the age-dependency of diabetes mellitus influence on the reliability of our chosen iris recognition system. Our results give some general hints related to age effect on performance of biometric systems for people with diabetes.
