Recognition and Analysis of Emotion in Indonesian Conversational Speech

The importance of incorporating emotional aspect in human computer interaction continues to arise. Unfortunately, exploration of the subject in Indonesian is still very lacking. This paper presents the first study of emotion recognition in Indonesian on conversational speech. We construct our corpus, IDESC, by making use of television talk show recordings in various topics of discussion, yielding colorful emotional utterances. Using the corpus, we then build a support vector machine (SVM) that classifies Indonesian speech in terms of emotion based on its acoustic features. We perform feature selection and parameter optimization while building the classifier to optimize the recognition performance, resulting in absolute 11.9% increase of accuracy. Lastly, we perform analyses on our corpus and evaluation result to gain better insight of emotion occurence in Indonesian speech.
Evaluation of cluster K-Means as VM selection in dynamic VM consolidation

The paper focused on the evaluation of K-Means as VM Selection in Dynamic VM Consolidation. The research has compared the performance of several numbers of cluster K-Means in VM selection with another method such as Minimum Migration Time (MMT) and Random Choice (RC). Several attributes such as MIPS VM and RAM VM have been used for clustering the VMs using K-Means. Besides that, in the overload detection mechanism that works before VM selection, we used Median Absolute Deviation (MAD) during evaluation. Moreover, workload PlanetLab and CloudSim were used in the evaluation process. The parameter measurements in this research are Energy Consumption, SLAV, SLATAH, and PDM. The evaluation results have shown the different number of cluster in K-Means has influenced performance of VM selection in dynamic VM consolidation. K-Means also able to reduce energy consumption in cloud data center compared with other VM Selection methods.
Health surveillance for noise-induced hearing loss (NIHL).

Ross et al. [1] compared hearing loss in divers and offshore workers and concluded that current Health & Safety Executive (HSE) guidance on the assessment of audiograms is ‘in error’ and ‘inadequate’. Grading the sum of hearing thresholds at 1, 2, 3, 4 and 6 kHz using the HSE ‘age-adjusted norm’ values [2], they found that the HSE scheme missed referring roughly half of people thought to have severe noise-induced hearing loss (NIHL) on additional medical review of audiograms. Why is this not surprising? Hansen [3] went some way to explaining in a 2007 criticism of current guidance. Hansen observed that the typical 4 kHz notch of noise damage may be masked when viewing the sum of thresholds (1–6 kHz) and also called into question the gender difference in the HSE scheme. Hansen expressed concern at the basis for the guidance and apparent reliance on a single piece of research. The introduction of new guidance in 2005 was based [3,4] on Prof. Adrian Davis’ work on the National Survey of Hearing completed in 1989. His 1989 paper [5] described hearing impairment and hearing disability in adults randomly selected from the electoral register in four cities (Cardiff, Glasgow, Nottingham and Southampton). Defining ‘significant hearing impairment’ as $25 dB hearing loss averaged over 0.5, 1, 2 and 4 kHz, Davis found that one in four of his population (age 17–80 years) had significant impairment and this was bilateral in roughly two-thirds of cases. The 2004 HSE proposal [4] to adopt the 80th and 95th centiles of summed thresholds (1–6 kHz) from National Survey of Hearing data as warning and referral levels for NIHL surveillance was largely based on estimated numbers of people referred or warned. It predicted that number of persons referred would fall by almost 40%. Sensitivity and specificity, or positive and negative predictive values, were not considered—except for one flawed statement referring to ‘problems’ with the pre-2005 scheme that ‘any scheme that warns almost 50% of an age group cannot be considered sensitive’. It is interesting to reflect that Ross et al. reported finding an indication of some degree of NIHL on audiogram assessment in 50% of divers and offshore workers studied. The HSE categorization scheme appears to provide a tool only for comparing the sum of hearing thresholds at 1–6 kHz against the hearing ability of an urban UK adult population including a substantial burden of significant hearing impairment from all causes. It has never been presented in a peer-reviewed journal as an appropriate method of detecting early or significant NIHL. Further work is required to determine whether a suitable and effective method for conducting meaningful health surveillance for NIHL exists.
A two-year weight reduction program in obese sleep apnea patients.

STUDY OBJECTIVES To evaluate the effects of a 2-year weight reduction program on respiratory disturbances, arousal index, daytime sleepiness, metabolic status, and quality of life in obese patients with obstructive sleep apnea syndrome (OSAS). METHODS Prospective intervention study of 33 consecutive obese OSAS patients (24 men, 9 women); 19 subjects used continuous positive airway pressure and 4 used mandibular retaining device, except during nights with sleep recording. The program consisted of 8 weeks of low calorie diet followed by group meetings with behavioral change support. RESULTS Seventy percent of the patients completed the program; 67% completed the sleep recordings. The success rate for the apnea-hypopnea index (AHI) (< 20 and reduction > or = 50%) was 15% in the intention to treat (ITT) analysis. The AHI showed a nonsignificant decrease in mean values, from 43 to 28. The oxygen desaturation index (ODI) decreased from 42 to 23 (p = 0.010), arousal index from 24 to 11 (p = 0.019), body mass index from 40 to 35 (p = 0.003) and the Epworth Sleepiness Scale (ESS) from 9 to 5 (p = 0.026), all ITT. Metabolic status, physical functioning, and vitality evaluations improved only in the per protocol analysis. Reduction in weight correlated significantly to reductions in ESS (p = 0.038) and insulin levels (p = 0.002), respectively. There were no differences based on gender or use/non-use of OSAS treatment device. CONCLUSIONS Our weight reduction program showed a limited success in reducing AHI. However, there were significant improvements in weight, ODI, arousal index, and subjective symptoms. We recommend the program as an adjunct treatment for well-motivated obese OSAS patients.
Interplay between orfamides, sessilins and phenazines in the control of Rhizoctonia diseases by Pseudomonas sp. CMR12a.

We investigated the role of phenazines and cyclic lipopeptides (CLPs) (orfamides and sessilins), antagonistic metabolites produced by Pseudomonas sp. CMR12a, in the biological control of damping-off disease on Chinese cabbage (Brassica chinensis) caused by Rhizoctonia solani AG 2-1 and root rot disease on bean (Phaseolus vulgaris L.) caused by R. solani AG 4-HGI. A Pseudomonas mutant that only produced phenazines suppressed damping-off disease on Chinese cabbage to the same extent as CMR12a, while its efficacy to reduce root rot on bean was strongly impaired. In both pathosystems, the phenazine mutant that produced both CLPs was equally effective, but mutants that produced only one CLP lost biocontrol activity. In vitro microscopic assays revealed that mutants that only produced sessilins or orfamides inhibited mycelial growth of R. solani when applied together, while they were ineffective on their own. Phenazine-1-carboxamide suppressed mycelial growth of R. solani AG 2-1 but had no effect on AG 4-HGI. Orfamide B suppressed mycelial growth of both R. solani anastomosis groups in a dose-dependent way. Our results point to an additive interaction between both CLPs. Moreover, phenazines alone are sufficient to suppress Rhizoctonia disease on Chinese cabbage, while they need to work in tandem with the CLPs on bean.
Molluscum Contagiosum Virus Interleukin-18 (IL-18) Binding Protein Is Secreted as a Full-Length Form That Binds Cell Surface Glycosaminoglycans through the C-Terminal Tail and a Furin-Cleaved Form with Only the IL-18 Binding Domain

ABSTRACT Some poxviruses and their mammalian hosts encode homologous proteins that bind interleukin-18 (IL-18) with high affinity and inhibit IL-18-mediated immune responses. MC54L, the IL-18 binding protein of the human poxvirus that causes molluscum contagiosum, is unique in having a C-terminal tail of nearly 100 amino acids that is dispensable for IL-18 binding. When recombinant MC54L was expressed and purified via a C-terminal six-histidine tag, a shorter fragment was detected in addition to the full-length protein. This C-terminal fragment resulted from the cleavage of MC54L by cellular furin, as it was greatly diminished when furin was specifically inhibited or when a furin-deficient cell line was used for expression. Furthermore, the N- and C-terminal fragments of MC54L were generated by cleavage of the recombinant protein with furin in vitro. The furin cleavage site was mapped within a 32-amino-acid segment that is C terminal to the IL-18 binding domain. Full-length MC54L, but not the N-terminal IL-18 binding fragment, bound to cells and to purified heparin and other glycosaminoglycans that are commonly found on the cell surface and in the extracellular matrix. MC54L bound to heparin with a nanomolar Kd and could simultaneously bind to IL-18. Their different glycosaminoglycan and cell binding properties may allow the long and short forms of MC54L to inactivate IL-18 near the site of infection and at more distal locations, respectively.
Low Reporting Quality of the Meta-Analyses in Diagnostic Pathology.

CONTEXT - Little is known regarding the reporting quality of meta-analyses in diagnostic pathology. OBJECTIVE - To compare reporting quality of meta-analyses in diagnostic pathology and medicine and to examine factors associated with reporting quality of diagnostic pathology meta-analyses. DESIGN - Meta-analyses were identified in 12 major diagnostic pathology journals without specifying years and 4 major medicine journals in 2006 and 2011 using PubMed. Reporting quality of meta-analyses was evaluated using the 27-item checklist of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement published in 2009. A higher PRISMA score indicates higher reporting quality. RESULTS - Forty-one diagnostic pathology meta-analyses and 118 medicine meta-analyses were included. Overall, reporting quality of meta-analyses in diagnostic pathology was lower than that in medicine (median [interquartile range] = 22 [15, 25] versus 27 [23, 28], P < .001). Compared with medicine meta-analyses, diagnostic pathology meta-analyses less likely reported 23 of the 27 items (85.2%) on the PRISMA checklist, but more likely reported the data items. Higher reporting quality of diagnostic pathology meta-analyses was associated with recent publication years (later than 2009 versus 2009 or earlier, P = .002) and non-North American first authors (versus North American, P = .001), but not journal publisher's location (P = .11). Interestingly, reporting quality was not associated with adjusted citation ratio for meta-analyses in either diagnostic pathology or medicine (P = .40 and P = .09, respectively). CONCLUSIONS - Meta-analyses in diagnostic pathology had lower reporting quality than those in medicine. Reporting quality of diagnostic pathology meta-analyses is linked to publication year and first author's location, but not to journal publisher's location or article's adjusted citation ratios. More research and education on meta-analysis methodology may improve the reporting quality of diagnostic pathology meta-analyses.
Optimal Nonrecursive Datalog Rewritings of Linear TGDs and Bounded (Hyper)Tree-Width Queries

Our concern is answering ontology-mediated queries (O, q), where O is a set of linear tgds and q a conjunctive query (CQ) of bounded hypertree width. Assuming that the arity of predicates is bounded, we show that polynomial-size nonrecursive Datalog rewritings can be constructed and executed in (i) LOGCFL for OMQs with ontologies of bounded existential depth; (ii) NL for OMQs with ontologies of bounded depth and CQs whose hypertree decompositions have a bounded number of leaves; (iii) LOGCFL for OMQs with acyclic CQs whose join trees have a bounded number of leaves.
The microfabrication of capacitive ultrasonic transducers

The successful fabrication of surface micromachined ultrasonic transducers is reported. In a key step of the microfabrication, amorphous silicon is used as a sacrificial layer to form sealed nitride cavities. The process is fully CMOS compatible and allows for improved geometric control compared to previously reported work. Transmission experiments in both water and air are presented. A dynamic range in excess of 110 dB is observed in air at 2.3 MHz. In water, a single pair of transducers is able to operate from 2 MHz to 20 MHz. When tuned, a 3 MHz tone burst results in a received signal with better than 60 dB signal to noise ratio. The transducer behavior agrees with theoretical understanding of transducer dynamics.
Modeling a Decision-Maker’s Choice Behavior Through Perceived Values

In the real world, an attribute value is perceived differently by different individuals. Emphasizing on this aspect, we extend the discrete choice models with perceived values that are subjective and specific to a decision-maker (DM). The proposed choice models are augmented with the parameters of an entropy function, besides the utility coefficients, to model a DM’s complex choice behavior. A variety of higher order choice models are also proposed. The proposed models are further extended with a DM’s reference-value for each attribute. A real and illustrative application is included.
Automated quantification and analysis of facial asymmetry in children with arthritis in the temporomandibular joint

We present an automated method of spatially detailed 3D asymmetry quantification of face surfaces obtained in a stereophotogrammetric system, and the method was applied to a population of children with juvenile idiopathic arthritis (JIA) who have involvement of one temporomandibular joint (TMJ). Non-rigid registration of a patient face surface to a mirrored version of the same face surface provided a spatially dense map of left-right point correspondences that were used in the asymmetry calculation. For inter-patient comparison and modeling, detailed point correspondence was obtained by non-rigid registration of a symmetric atlas surface to a symmetric version of the patient surface. The method was validated by comparison to a landmark based method of asymmetry quantification, and the two methods were seen to provide similar results. The method was seen to be able to quantify typical patterns of asymmetry in JIA subjects with affected TMJ and compare them to a control population.
Resource Allocation Based on Channel Distribution Information for Elastic and Streaming Traffic in OFDMA Networks: A Heuristic Algorithm

In this paper, we propose a low complexity heuristic algorithm for radio resource allocation in Orthogonal Frequency Division Multiple Access (OFDMA) systems based on subcarrier channel distribution information (CDI). We consider practical rate adaptation in which rate is adapted using a predefined set of modulation levels, which is in contrast to previous works that consider continuous rate. We formulate the problem of resource allocation in an OFDMA system with streaming traffic which requires a minimum guaranteed average rate, and elastic traffic with flexible rate requirements. The main objective is to maximize the total transmission rate of the elastic users, while average rate guarantees for streaming traffic as well as maximum transmission power constraints are satisfied. To reduce the computational complexity, we decouple the resource allocation problem into two sub-problems corresponding to two traffic types. For streaming traffic, we optimally allocate subcarrier and power and then the remaining radio resources including the unassigned subcarriers and unallocated transmission power of the base station are optimally allocated to the elastic traffic. We then develop a heuristic algorithm based on Lagrangian method to obtain an approximation of the optimal solution. Using simulations, we study the impact of number of fading regions. Simulations also provides insight on the trade-off between the number of streaming and elastic users.
A Pilot Study of the Effects of High-Intensity Aerobic Exercise Versus Passive Interventions on Pain, Disability, Psychological Strain, and Serum Cortisol Concentrations in People With Chronic Low Back Pain

Background and Purpose Given the complex nature of chronic pain, the effects of high-intensity aerobic exercise on pain, disability, psychological strain, and serum cortisol concentrations in people with chronic low back pain were investigated. Subjects Twenty subjects receiving primary health care were randomly allocated into exercise and control groups. Methods Subjects in the exercise group received a 12-week, high-intensity aerobic exercise program. Subjects in the control group received 12 weeks of passive modalities without any form of physical activity. Results Data analysis identified reductions in pain (41%, t10=8.51, P<.001), disability (31%, t10=7.32, P<.001), and psychological strain (35%, t10=7.09, P<.001) in subjects in the exercise group and no changes in subjects in the control group. High-intensity exercise failed to influence serum cortisol concentrations. Discussion and Conclusion Regular high-intensity aerobic exercise alleviated pain, disability, and psychological strain in subjects with chronic low back pain but did not improve serum cortisol concentrations.
An evaluation of existing risk stratification models as a tool for comparison of surgical performances for coronary artery bypass grafting between institutions q

Objective: Risk stratification systems are used in cardiac surgery to estimate mortality risk for individual patients and to compare surgical performance between institutions or surgeons. This study investigates the suitability of six existing risk stratification systems for these purposes. Methods: Data on 5471 patients who underwent isolated coronary artery bypass grafting at two UK cardiac centres between 1993 and 1999 were extracted from a prospective computerised clinical data base. Of these patients, 184 (3.3%) died in hospital. In-hospital mortality risk scores were calculated for each patient using the Parsonnet score, the EuroSCORE, the ACC/AHA score and three UK Bayes models (old, new complex and new simple). The accuracy for predicting mortality at an institutional level was assessed by comparing total observed and predicted mortality. The accuracy of the risk scores for predicting mortality for a patient was assessed by the HosmerLemeshow test. The receiver operating characteristic (ROC) curve was used to evaluate how well a system ranks the patient with respect to their risk of mortality and can be useful for patient management. Results: Both EuroSCORE and the simple Bayes model were reasonably accurate at predicting overall mortality. However predictive accuracy at the patient level was poor for all systems, although EuroSCORE was accurate for low to medium risk patients. Discrimination was fair with the following ROC areas: Parsonnet 0.73, EuroSCORE 0.76, ACC/AHA system 0.76, old Bayes 0.77, complex Bayes 0.76, simple Bayes 0.76. Conclusions: This study suggests that two of the scores may be useful in comparing institutions. None of the risk scores provide accurate risk estimates for individual patients in the two hospitals studied although EuroSCORE may have some utility for certain patients. All six systems perform moderately at ranking the patients and so may be useful for patient management. More results are needed from other institutions to confirm that the EuroSCORE and the simple Bayes model are suitable for institutional risk-adjusted comparisons. q 2003 Elsevier Science B.V.

Lactulose Breath Test Gas Production in Childhood IBS Is Associated With Intestinal Transit and Bowel Movement Frequency

Objectives: In adults with irritable bowel syndrome (IBS), bacterial gas production (colonic fermentation) is related to both symptom generation and intestinal transit. Whether gas production affects symptom generation, psychosocial distress, or intestinal transit in childhood IBS is unknown. Methods: Children (ages 7–17 years) with pediatric Rome III IBS completed validated psychosocial questionnaires and a 2-week daily diary capturing pain and stooling characteristics. Stool form determined IBS subtype. Subjects then completed a 3-hour lactulose breath test for measurement of total breath hydrogen and methane production. Carmine red was used to determine whole intestinal transit time. Results: A total of 87 children (mean age 13 ± 2.6 [standard deviation] years) were enrolled, of whom 50 (57.5%) were girls. All children produced hydrogen and 51 (58.6%) produced methane. Hydrogen and methane production did not correlate with either abdominal pain frequency/severity or psychosocial distress. Hydrogen and methane production did not differ significantly by IBS subtype. Methane production correlated positively with whole intestinal transit time (r = 0.31, P < 0.005) and inversely with bowel movement frequency (r = −0.245, P < 0.05). Methane production (threshold 3 ppm) as a marker for identifying IBS-C had a sensitivity of 60% and specificity of 42.9%. Conclusions: Lactulose breath test total methane production may serve as a biomarker of whole intestinal transit time and bowel movement frequency in children with IBS. In children with IBS, lactulose breath test hydrogen and methane production did not, however, correlate with abdominal pain, IBS subtype, or psychosocial distress.
The Role of the Notary Regional Supervisory Board in Preventing Legal Violations Committed by Notaries in Padang City

The authority of the notary is very susceptible of legal violations. The role of the supervisory board is very important to maintain the notary profession in carrying out the authority. Law enforcement is urgently needed when a violation arises, in which a troubled notary must be sanctioned. Conducting research in the form of scientific work that studies the following research problems will be interesting: (1) what factors are the cause of legal violations committed by notaries in Padang City? (2) what is the role of the Regional Supervisory Board in preventing legal violations committed by notaries in Padang City? and (3) what actions are taken by the Regional Supervisory Board against the notaries who commit legal violations in Padang City. This study applies juridical empirical approach using secondary and primary data types. The Regional Supervisory Board of Padang City mentioned that the factors causing legal violations committed by the notaries in Padang City are that (1) the notary likes to accept a work that is not in accordance with the date stated in the deed and (2) the notary often does not see the client directly. Legal violations committed by notaries in Padang City can be prevented by conducting socialization and direct observation in the field. The action that can be taken if legal violations committed by notaries occurs is to carry out the inspection process in order to prove whether or not the notary has committed a violation.
