AUTOMATED COMPLAINTS CLASSIFICATION USING MODIFIED NAZIEF-ADRIANI STEMMING ALGORITHM AND NAIVE BAYES CLASSIFIER

Complaints provided by customers in the use of products or services is a feedback of the quality of products or services used by customers. In Universitas Multimedia Nusantara (UMN), students can deliver their complaints through an organization, i.e. Dewan Keluarga Besar Mahasiswa (DKBM) UMN. All students’ complaints are manually classified into predefined categories by DKBM so that it can be delivered to related division. It costs a lot of time and human resources of DKBM UMN, and also caused misclassification of incoming complaints. In e-complaint system, a method that can be used to support efficient complaint processing is the use of automatic classification system because it can save both time and human resources. Naive Bayes Classifier (NBC) algorithm is one the algorithm that can be used to classify text automatically and for the preprocessing stage, modified Nazief-Adriani stemming algorithm is used. Based on the study conducted, it can be concluded that Naive Bayes Classifier algorithm with modified Nazief-Adriani stemming algorithm is able to do the classification well. This is indicated from the precision value of 91.86%, the recall value of 84.48%, and the f-1 score value of 86.29% for the ratio of training data and test data 90:10, and an average accuracy of 86%.
Contribution of the Periplasmic Chaperone Skp to Efficient Presentation of the Autotransporter IcsA on the Surface of Shigella flexneri

ABSTRACT IcsA is an outer membrane protein in the autotransporter family that is required for Shigella flexneri pathogenesis. Following its secretion through the Sec translocon, IcsA is incorporated into the outer membrane in a process that depends on YaeT, a component of an outer membrane β-barrel insertion machinery. We investigated the role of the periplasmic chaperone Skp in IcsA maturation. Skp is required for the presentation of the mature amino terminus (alpha-domain) of IcsA on the bacterial surface and contributes to cell-to-cell spread of S. flexneri in cell culture. A mutation in skp does not prevent the insertion of the β-barrel into the outer membrane, suggesting that the primary role of Skp is the folding of the IcsA alpha-domain. In addition, the requirement for skp can be partially bypassed by disrupting icsP, an ortholog of Escherichia coli ompT, which encodes the protease that processes IcsA between the mature amino terminus and the β-barrel outer membrane anchor. These findings are consistent with a model in which Skp plays a critical role in the chaperoning of the alpha-domain of IcsA during transit through the periplasm.
Effects of Short-Term Psychological Stress on the Time and Frequency Domains of Heart-Rate Variability

The purpose of this study was to test the hypothesis that short-term psychological stress produces significant changes in sympathovagal activity. A simple, noninvasive method was used measuring the timing and frequency of heart-rate variability (HRV). 30 normal healthy subjects were assigned into two age- and sex-matched groups. In the experimental condition a 5-min. psychological stress test, predominantly based on the Stroop Word Color Conflict Test, was employed in a competitive setting and included a financial inducement to produce psychological strain. Analysis showed that during psychological stress a significant reduction in the timing and frequency of heart-rate variability was observed. The standard deviation of interbeat intervals decreased. A significant increase in heart rate was also observed. Within the frequency domain, a significant reduction in the high frequency component of HRV and a significant increase in the low frequency component were observed. There was also a significant increase in the low frequency to high frequency ratio. Self-evaluation of physical tension and emotional state measured by visual analog scales also showed significant increases following psychological stress. No significant differences were observed on any variables within the control group. The results indicate a shift towards sympathetic predominance as a result of parasympathetic withdrawal and demonstrates that this psychological stress test is effective in provoking a characteristic defence-arousal reaction. This simple, cost-effective method of analysing heart-rate variability is suitable for detection of short-term changes in sympathovagal balance.
Multi-sensory storytelling for persons with profound intellectual and multiple disabilities: an analysis of the development, content and application in practice.

BACKGROUND Multi-sensory storytelling (MSST) books are individualized stories, which involve sensory stimulation in addition to verbal text. Despite the frequent use of MSST in practice, little research is conducted into its structure, content and effectiveness. This study aims at the analysis of the development, content and application in practice of the MSST books in persons with profound intellectual and multiple disabilities (PIMD). MATERIALS AND METHODS Forty-nine persons with PIMD and their direct support person participated. We analysed if the books are constructed and read according to guidelines. Content and used stimuli were related to age. RESULTS Of the books 84% were constructed according to guidelines. In just 1.3% of the sessions, the story was read as intended. Regarding content, 67.4% of the stories focused on daily life excursions. Tactile stimuli were used most. Age related to stimuli choice, but not to content. CONCLUSIONS Although most books were properly constructed, guidelines were barely followed during reading which may negatively influence the effectiveness.
A High-Order Sliding-Mesh Spectral Difference Solver for Simulating Unsteady Flows around Rotating Objects

In this paper, we report a high-order three-dimensional sliding-mesh algorithm for compressible Navier-Stokes equations and simulations of unsteady flows around 3D rotating objects. This 3D sliding-mesh method is an extension of our previously published 2D sliding-mesh methods [34, 35] based on the spectral difference method. Similar to other sliding-mesh methods, a computational domain is split into non-overlapping subdomains, and each one may have rotational motions relative to its neighbors, resulting in nonconforming sliding interfaces in between. Our sliding-mesh method is unique because two neighboring subdomains are coupled through curved dynamic mortar elements along the sliding interfaces. In order to compute common solutions and fluxes on mortars, both conservative variables and fluxes are first projected from cell faces to mortar elements. Subsequently, they are projected back to cell faces to ensure conservation. To demonstrate the accuracy of the solver, both inviscid and viscous benchmark flows are tested. The solver is shown capable of preserving the high-order accuracy of the background spectral difference method. This solver is also able to handle sliding interfaces with different orientations, is thus very flexible for flow simulations with complex geometries. Numerical tests are also carried out on more complex flows, such as flow around a rotating elliptic cylinder, transitional TaylorCouette flow with multiple sliding interfaces, and flows around a rotating cube. This solver can be applied to a wide range of rotating flow problems, for example, flows around wind turbines, marine propellers, etc.
Adolescent physical activities as predictors of young adult weight.

OBJECTIVE To examine the relationship between increased physical activity in adolescence and adult weight status. DESIGN Cohort study based on data from the National Longitudinal Study of Adolescent Health. SETTING In-home interviews. PARTICIPANTS A total of 3345 adolescents in grades 8 to 12 with body mass index (calculated as weight in kilograms divided by height in meters squared) data available at baseline and 5 years later. Main Exposures Days per week of curricular and extracurricular physical activity. MAIN OUTCOME MEASURE Overweight status (body mass index > or =25) 5 years after baseline. RESULTS Increasing participation in certain extracurricular physical activities and physical education decreased the likelihood of young adulthood overweight. Regarding extracurricular physical activities, the likelihood of being an overweight adult was reduced most (ie, 48%) by performing certain wheel-related activities (ie, rollerblading, roller skating, skateboarding, or bicycling) more than 4 times per week. Each weekday that adolescents participated in physical education decreased the odds of being an overweight adult by 5%, with participation in all 5 weekdays of physical education decreasing the odds by 28%. In general, physical activity predicted normal-weight maintenance better than weight loss. CONCLUSION These data underscore the important role that school-based and extracurricular physical activity play in reducing the likelihood of transitioning to overweight as young adults.
TIE-40 Optical glass for precision molding 1

To overcome such restrictions and to reduce the processing expense, precision molding technologies for direct pressing of aspherical lenses have been developed in the past years worldwide. The process of precise molding (figure 1) starts from a polished or firepolished preform. The surface of such a preform must be of very good quality with respect to surface roughness and defects. Such a preform can be a polished ball, a fire-polished rod, a precision gob (a firepolished preform produced directly from the melt without any additional surface processing) or any other polished lens preform (disc or near shape generated out of raw glass by conventional hot forming or grinding and polishing steps). During the precision molding process, the preform is shaped into its final (often aspherical) geometry, while conserving the surface quality of the preform. The molding process is a low temperature molding process with typical temperatures between 500°C and 700°C. Low temperature processes help to lengthen the operating lifetime of the mold material.
Underlying concepts in robustness and resilience and their use in designing socio-technical systems

The aim of this paper is to make a conceptual distinction between the notions of robustness and resilience. Currently these terms are used in with many different meanings. This heterogeneity is increased by the fact that these terms are related to key concepts in many different fields (computer science, biology, economics, etc.) and are related to different conceptual meanings (stability, non-equilibrium dynamics, etc.). In this paper we argue that robustness and resilience, regardless of processes to which they are associated, belong to two types of regulation: functional and structural. Functional regulation refers to the classical engineering view of regulation as a process that tries to restore the initial functions of the system. Conversely, structural regulation refers to non-equilibrium dynamics (or autopoiesis, self-organisation, critical self-organisation, etc.) with the aim of finding a new equilibrium between the components of the system. Using examples from emergency and crisis management, we show how emergent and self-organised regulation can play a critical role in achieving robust socio-technical systems. The ultimate goal of this paper work is to propose a methodology for designing robust socio-complex systems based on this approach.
From audiences to mobs: Crowd simulation with psychological factors (Kitlelerden güruhlara: Psikolojik faktörlerle kalabalık simülasyonu)

FROM AUDIENCES TO MOBS: CROWD SIMULATION WITH PSYCHOLOGICAL FACTORS Funda Durupınar Ph.D. in Computer Engineering Supervisor: Assoc. Prof. Dr. Uğur Güdükbay July, 2010 Crowd simulation has a wide range of application areas such as biological and social modeling, military simulations, computer games and movies. Simulating the behavior of animated virtual crowds has been a challenging task for the computer graphics community. As well as the physical and the geometrical aspects, the semantics underlying the motion of real crowds inspire the design and implementation of virtual crowds. Psychology helps us understand the motivations of the individuals constituting a crowd. There has been extensive research on incorporating psychological models into the simulation of autonomous agents. However, in our study, instead of the psychological state of an individual agent as such, we are interested in the overall behavior of the crowd that consists of virtual humans with various psychological states. For this purpose, we incorporate the three basic constituents of affect: personality, emotion and mood. Each of these elements contribute variably to the emergence of different aspects of behavior. We thus examine, by changing the parameters, how groups of people with different characteristics interact with each other, and accordingly, how the global crowd behavior is influenced. In the social psychology literature, crowds are classified as mobs and audiences. Audiences are passive crowds whereas mobs are active crowds with emotional, irrational and seemingly homogeneous behavior. In this thesis, we examine how audiences turn into mobs and simulate the common properties of mobs to create collective misbehavior. So far, crowd simulation research has focused on panicking crowds among all types of mobs. We extend the state of the art to simulate different types of mobs based on the taxonomy. We demonstrate various scenarios that realize the behavior of distinct mob types. Our model is built on top of an existing crowd simulation system, HiDAC iv
Cognitive Control as Cost‐Benefit Decision Making

© 2017 John Wiley & Sons, Ltd. Published 2017 by John Wiley & Sons, Ltd. Many everyday situations afford us a set of default behaviours and cognitive processes that could play out automatically in response to stimuli in our environment. Cognitive control enables us to modify our thoughts and actions away from those defaults in a variety of ways, allowing us as a species to perform great intellectual feats such as planning (D. A. Simon & Daw, 2011), reasoning (Christoff et al., 2001), inhibition (Aron, 2011), and working memory maintenance (Goldman‐Rakic, 1987). But what is it that determines when we exert control, how much we do so, and what form(s) this control takes? In other words, by what computational and neural mechanisms is the controller itself controlled (Botvinick & Cohen, 2015; Dayan, 2012)? In this chapter, we address this question by framing it as a reward‐based decision‐making problem. This approach views the exertion of cognitive effort as being determined by the output of a decision that considers both the costs and benefits of mobilising cognitive control at a given moment. We begin by enumerating a set of factors that weigh in favour of the exer­ tion of control and those that oppose it. We then present a theoretical framework that spec­ ifies how these costs and benefits are integrated together to form a decision about whether and how control should be deployed. Finally, we describe the neural underpinnings of this decision process, with a particular focus on the role of the dorsal anterior cingulate cortex (dACC) in determining how best to allocate control.
Penetrance of LGI1 mutations in autosomal dominant partial epilepsy with auditory features

Background: Assessment of the penetrance of disease-causing mutations is extremely important for developing clinical applications of gene discovery, such as genetic testing and counseling. Mutations in the leucine-rich, glioma inactivated 1 gene (LGI1) have been identified in about 50% of families with autosomal dominant partial epilepsy with auditory features (ADPEAF), but estimates of LGI1 mutation penetrance have ranged widely, from 50 to 85%. The current study aimed to provide a more precise estimate of LGI1 mutation penetrance. Methods: We analyzed data from all 24 previously published ADPEAF families with mutations in LGI1. To estimate penetrance, we used the information from the published pedigree figures to determine the proportion of obligate carriers who were affected. We assessed whether penetrance was associated with the total number of affected individuals in each family, or mutation type (truncating or missense) or location within the gene. We also compared penetrance in males and females, and among different generations within the families. Results: Overall penetrance was 67% (95% CI 55–77%), and did not vary according to mutation type or location within the gene. Penetrance was greater in families with more affected individuals, but this trend was not significant. Penetrance did not differ by gender but increased with advancing generation, probably because of limited information about early generations. Conclusions: Our results suggest that about two-thirds of individuals who inherit a mutation in LGI1 will develop epilepsy. This probably overestimates the true penetrance in the population because it is based on data from families containing multiple affected individuals.
TLR9-Dependent IL-23/IL-17 Is Required for the Generation of Stachybotrys chartarum–Induced Hypersensitivity Pneumonitis

Hypersensitivity pneumonitis (HP) is an inflammatory lung disease that develops after repeated exposure to inhaled particulate Ag. Stachybotrys chartarum is a dimorphic fungus that has been implicated in a number of respiratory illnesses, including HP. In this study, we have developed a murine model of S. chartarum–induced HP that reproduces pathology observed in human HP, and we have hypothesized that TLR9-mediated IL-23 and IL-17 responses are required for the generation of granulomatous inflammation induced by inhaled S. chartarum. Mice that undergo i.p. sensitization and intratracheal challenge with 106 S. chartarum spores developed granulomatous inflammation with multinucleate giant cells, accompanied by increased accumulation of T cells. S. chartarum sensitization and challenge resulted in robust pulmonary expression of IL-17 and IL-23. S. chartarum–mediated granulomatous inflammation required intact IL-23 or IL-17 responses and required TLR9, because TLR9−/− mice displayed reduced IL-17 and IL-23 expression in whole lung associated with decreased accumulation of IL-17 expressing CD4+ and γδ T cells. Compared with S. chartarum–sensitized dendritic cells (DC) isolated from WT mice, DCs isolated from TLR9−/− mice had a reduced ability to produce IL-23 in responses to S. chartarum. Moreover, shRNA knockdown of IL-23 in DCs abolished IL-17 production from splenocytes in response to Ag challenge. Finally, the intratracheal reconstitution of IL-23 in TLR9−/− mice recapitulated the immunopathology observed in WT mice. In conclusion, our studies suggest that TLR9 is critical for the development of Th17-mediated granulomatous inflammation in the lung in response to S. chartarum.
EFFECT OF FEEDING CORIANDER SEEDS , BLACK PEPPER AND TURMERIC POWDER AS FEED ADDITIVES ON HEMATO-BIOCHEMICAL PROFILE AND PERFORMANCE OF BROILER CHICKEN

This study was undertaken to investigate the effect of feeding coriander seeds, black pepper and turmeric powder, as a growth promoter in broiler feed on growth performance, carcass characteristics and blood profile. A total 240 day-old commercial broiler chicks (Cobb-400) were divided equally into four groups with 60 birds (three replicates each of 20 birds) and were assigned to four iso-nutritive diets, viz., Diet-I (basal control diet without feed additives), Diet-II (basal control diet with 2 % Coriander seeds), Diet-III (basal control diet with 2 % Turmeric powder) and Diet-IV (basal control diet with 0.5 % Black pepper). Feed and water were offered ad libitum till the termination of the trial at 42 days. The starter and finisher diets were given to birds from 1 to 28 and 29 to 42 days of age, respectively. Growth performance and blood parameters were measured. Overall feed intake (g) was found to be significantly (P<0.05) higher in different treatment groups as compared to control group with highest value for T3 group followed by T2, T4 and T1 groups. Final body weights (g) were found to be significantly (P<0.05) higher in all treatment groups (T2,T3 and T4) as compared to control group (T1) and highest total body weight of experimental birds was observed in coriander seed supplemented group (T2) followed by black pepper (T4), turmeric (T3) and control group (T1). Difference in feed conversion ratio was found to be non significant among control (T1), T2, T3 and T4 group. Non significant (P>0.05) difference for different haemato biochemical parameters like Hemoglobin (Hb), Packed cell volume (PCV), Total Erythrocyte Count (TEC), Total Leukocyte Count (TLC) and Alanine Amino Transaminase (ALT) were observed. Aspartate amino transferase (AST) value which was significantly higher in treatment groups (T2, T3, T4) as compare to control (T1). The results of the present investigation indicated that use of coriander seed @ of 2% improves the overall performance without any harmful effect on hemato-biochemical profile and can be included in the diet of broilers up to 42 days to maximize the profit.
Some effects of nutrition and management on the fertility of dairy cattle

When 24 cows were classified according to whether they had a better or worse energy status (defined as a plasma beta-hydroxybutyrate level below or above 15 mg/100 ml and a plasma glucose level above or below 55 mg/100 ml) the median interval between calving and the onset of cyclicity was shorter and conception rates were better for the cows with a better energy status at seven and 14 days after calving. This was not repeated when the cows' energy status was assessed as better at either 21 days after calving or at the time of service. In the same group of cows there was a positive correlation between the loss of condition score in early lactation and beta-hydroxybutyrate levels. In a further trial 15 cows fed a silage-based diet during the dry period had better conception rates and greater luteinising hormone responses to buserelin than 14 cows fed a straw-based diet. The straw-fed cows lost more weight before calving and had significantly higher non-esterified fatty acid levels. After calving both groups of cows were fed the same diet but the cows fed straw in the dry period produced less milk and lost less weight than the cows fed silage. Dry cow nutrition affected subsequent fertility and production. The non-esterified fatty acid level in the last week or two of pregnancy is suggested as a practical indication of the level of dry cow nutrition and its probable effect on productivity. No relationships were observed between plasma urea concentrations and the fertility of the cows.
