Udang vanname (Litopenaeus vannamei) merupakan salah satu jenis udang yang umum dibudidayakan di Indonesia sejak pemerintahan mengeluarkan kebijakan untuk mengintroduksinya sebagai upaya menanggulangi penurunan produksi. Kehadiran udang vanname di Indonesia pada awalnya dapat diterima dan berkembang dengan baik oleh pembudidaya udang. Namun, produksi udang mengalami kemerosotan beberapa tahun terakhir seiring kemunculan penyaki. Virus disinyalir menjadi patogen paling berperan memicu penyakit pada udang. Tujuan dari penelitian ini adalah untuk mendeteksi keberadaan WSSV pada udang vanname (Litopenaeus vannamei) secara molekuler serta memperoleh keterkaitan antara kualitas air dengan keberadaan udang yang terinfeksi WSSV. Pengambilan sampel dilakukan di PT. Hasfam Inti Sentosa. Sampel di ambil secara acak dari 5 kolam yang berbeda pada hari ke 35 dan ke 70. Deteksi molekuler WSSV dilakukan di SKIPM Kelas II Bengkulu menggunakan Pockit Real Time PCR. Hasil identifikasi molekuler menunjukkan bahwa tidak terdapat virus WSSV atau negatif (-) WSSV pada udang yang berasal dari PT. Hasfam Inti Sentosa. Kualitas air secara keseluruhan optimal untuk budidaya udang vanname kecuali parameter ammonia dan nitrit. Tetapi parameter ammonia masih dalam batasan toleransi untuk udang vanname sehingga kualitas air tambak masih belum menyebabkan udang terinfeksi WSSV.

Published: May 2018

Objetivo: establecer la utilidad de los valores del volumen plaquetario medio en el segundo trimestre del embarazo como predictor del desarrollo de preeclampsia. Materiales y métodos: investigación prospectiva en 504 pacientes nulíparas con embarazos simples entre 17 y 20 semanas que acudieron a la consulta prenatal. Se evaluaron las características generales, valores del volumen plaquetario medio y eficacia pronóstica. Resultados: los casos fueron 41 embarazadas que desarrollaron preeclampsia (grupo A) y 463 embarazadas consideradas controles (grupo B). No se encontraron diferencias estadísticas significativas en la edad materna, edad gestacional y presión arterial sistólica y diastólica al momento de la realización de la ecografía (p = ns). La edad gestacional al momento del diagnóstico de preeclampsia en el grupo A fue de 35,0 +/- 3,2 semanas. Se encontraron diferencias estadísticamente significativas en los valores del volumen plaquetario medio entre el grupo A (10,15 +/- 0,57 fL) y el B (9,65 +/- 0,61 fL; p < 0,0001). Un valor de corte de 9,50 fL presentó una cifra por debajo de la curva de 0,714 y tiene sensibilidad de 85,4%, especificidad del 40,6%, valor predictivo positivo del 11,3% y valor predictivo negativo del 96,5%. Conclusión: los valores del volumen plaquetario medio en el segundo trimestre no son útiles en la predicción del desarrollo de preeclampsia.

Salinity is one of the major abiotic stresses, and it limits rice production in many worldwide areas. A lot of attention has been paid to developing rice salinity tolerance to cope with climate change. This study is based on the genome sequence databases of 36 Vietnamese landraces. The candidate gene, SRWD2, has been predicted and identified. The salt responsive WD40 protein 2 is involved in salt tolerance yield of nine rice landraces. Specifically, nine homologous segments of the sequences were found to be components of the CSD nucleotides, which is shown to be similar to the reference genome LOCOs02g48964.1 and LOCOs02g48964.1 CDS, respectively. At the same time, the functional marker, SRWD2add14, was designed to identify the candidate gene, SRWD2, based on its size as 150 bp (candidate gene tolerant to salinity) and 136 bp (different sequences to compare SRWD2-reference genome sequence). The findings show that Mot bui do landrace carries the candidate gene, SRWD2 (homozygote). The rice genotype should be used as a potential material for rice breeding to develop salt tolerance in rice varieties.
Evaluación del intervalo hídrico óptimo en un brunosol éutrico típico bajo diferentes intensidades de uso agrícola
Authors: Rubio Dellepiane Valentina , Gama Roldán Diana , Pérez Bidegain Mario , Quincke Andrés
Published: May 2018

El intervalo hídrico óptimo (IHO) fue propuesto como un indicador de calidad física de suelo que integra en un único parámetro los efectos de la aireación, la resistencia a la penetración y el contenido de agua del suelo sobre el crecimiento vegetal. El objetivo del presente estudio fue evaluar el IHO, conjuntamente con otras propiedades físicas del suelo, bajo diferentes sistemas de rotación y fertilización. Las determinaciones se desarrollaron en un Brunosol éutrico típico en Colonia, Uruguay, sobre un experimento de largo plazo de rotaciones agrícola-pastoriles, iniciado en el año 1963. Los tratamientos evaluados fueron: a) agricultura continua sin fertilización (ACs / Fert); b) agricultura continua fertilizada (AC); c) rotación de cultivos y pasturas con 50 % del tiempo bajo cultivos (50 % Cult) y d) rotación de cultivos y pasturas con 33 % del tiempo bajo cultivos (33 % Cult). El IHO disminuyó debido al incremento en la intensidad agrícola, variando entre 0,08 y 0,02 cm3 cm-3 para los tratamientos 33 % Cult y ACs / Fert respectivamente, permitiendo detectar un deterioro en la calidad física de los suelos. El análisis de los límites que conforman el indicador permite entender las posibles limitantes a las que se enfrentan los cultivos, mostrando que la aireación y resistencia a la penetración resultan más limitantes a mayor intensidad de uso agrícola del suelo.

Published: May 2018

Se realizó un ensayo con el objetivo de evaluar el efecto sobre el comportamiento productivo de cerdos en engorde de sustituir el maíz por distintos tipos y formas de presentación de sorgo granífero. Se evaluaron cinco tratamientos, consistentes en dietas isoproteicas e isoenergéticas: T1: (control) en base maíz/soja; T2: grano de sorgo bajo en taninos (SBT) en sustitución del maíz; T3: ensilado grano húmedo (SGH) de SBT en sustitución del maíz; T4: SGH de sorgo con contenido medio de taninos (SMT) en sustitución del 50 % del maíz; T5: grano de SMT en sustitución del 50 % del maíz. Se utilizaron 30 cerdos, seis por tratamiento, que fueron evaluados entre los 35 y 105 kg de peso vivo. Se realizó alimentación a voluntad. Se evaluaron los parámetros ganancia diaria de peso, consumo diario de alimento e índice de conversión del alimento ajustado a 90 % de materia seca. No se observaron diferencias entre tratamientos para ninguno de los parámetros evaluados. Se concluye que el SBT, en forma de grano seco molido o SGH puede remplazar totalmente al grano de maíz en dietas para cerdos en engorde sin que se afecten los parámetros de respuesta productiva. A su vez es posible la sustitución del 50 % del maíz por SMT en forma de grano seco o SGH sin consecuencias sobre el resultado productivo.

Authors: Hirigoyen Andrés , Franco Jorge , Diéguez Ulises
Published: May 2018

Los modelos dinámicos a nivel de rodal son ampliamente usados en el ámbito forestal. Para su ajuste se emplean datos empíricos que se integran en un conjunto de ecuaciones que describen las relaciones entre diferentes variables. Las metodologías clásicas para desarrollar ecuaciones de transición invariantes con respecto al intervalo de simulación (path invariance) e invariantes respecto a la edad de referencia empleadas son algebraic difference approach (ADA) y generalized algebraic difference approach (GADA). El objetivo de este trabajo fue desarrollar un modelo dinámico de rodal para Eucalyptus globulus, empleando ecuaciones de transición para área basal, altura media dominante y mortalidad, utilizando enfoque de variables dummy. Los datos utilizados provienen de 168 parcelas permanentes. Las ecuaciones evaluadas individualmente fueron luego ajustadas simultáneamente mediante seemingly unrelated regression (SUR). En base al análisis de bondad de ajuste y de la capacidad predictiva, se seleccionó el modelo propuesto por Korf, modificado por Cieszewski (2004), para la altura media dominante; el modelo de Levakovic (Zeide, 1993), para el área basal y el modelo de Pienaar y Shiver (1981) para la mortalidad. El modelo de simulación desarrollado es más flexible y permite levantar algunas de las limitantes del modelo utilizado anteriormente. Su integración a sistemas de apoyo a la toma de decisiones constituirá una herramienta de gran utilidad para la planificación y toma de decisiones en el sector forestal.

Authors: Damayanti Desy , Fauzi Adin , Inayati Azizatul Mahfida
Published: May 2018

Among some components of effective language classroom, learning materials indisputably play a focal role. They improve the quality of language teaching; facilitate teachers in doing their duties, and lead students to a higher level of understanding in learning. This research aims to discuss the notion of materials in language teaching. It made use of works of literature to outline the importance of materials in language teaching, and to analyze kinds of materials, which are relevant to language teaching. The analysis resulted in the classification of materials into two broad categories namely (1) created materials, which include course book, audio materials, and video materials; and (2) authentic materials, which cover authentic texts, movie/film, radio broadcasting, television program, graphs, maps, tables, and charts. This paper serves as an invaluable resource to facilitate language teachers in selecting appropriate materials for effective language teaching.

Analyses of \pi^{\pm} nucleus elastic scattering data at T_\pi = 40, 30, 20 MeV using a suggested scaling method
Authors: Shehadeh Zuhair F. , El-Shawaf Reham M.
Published: May 2018

The data for elastically scattered charged pions from few nuclei, namely ^{12}C, ^{16}O, ^{28}Si, ^{32}S, ^{40}Ca, ^{56}Fe, ^{58}Ni, and ^{90}Zr have been analyzed by obtained potentials using a suggested scaling procedure. Originally the \pi ^{\pm}-^{12}C elastic scattering data at 50 MeV was nicely fitted by a parameterized simple local optical potential extracted from available phase shifts using inverse scattering theory. The potential parameters of the  \pi ^{\pm}-^{12}C systems were scaled to  \pi ^{\pm}-^{16}O systems and then successively to other few systems covering the scattering of charged pions from target nuclei, namely \pi ^{\pm}-^{28}Si, \pi ^{\pm}-^{32}S, \pi ^{\pm}-^{40}Ca, \pi ^{\pm}-^{56}Fe, \pi ^{\pm}-^{58}Ni and \pi ^{\pm}-^{90}Zr . The obtained scaled potentials showed a remarkable success in explaining the available measured elastic differential cross sections, and in predicting other ones for the systems under consideration. The reaction cross sections have been calculated for all these systems at the three incident pion's kinetic energies, T\pi = 40, 30, 20 MeV. Unfortunately, experimental reaction cross sections are totally absent or cloudy and unconfident. As such, and at this stage, we consider our calculated values useful and pending for future investigations.  For the systems and energies considered herein, simple scaling relations are well established. This will be beneficial in analyzing similar nuclear scattering data, as low-energy pion-nucleus and kaon-nucleus elastic scattering data; and, hopefully, in explaining pionic atom data.
Between Middlemen and Interlopers: History, Diaspora, and Writing on the Lebanese of West Africa
Authors: Malki I.P.X.
Published: May 2018

This article explores representations of the Lebanese in West Africa from the colonial to the postcolonial and contemporary eras. It contextualizes a diverse body of scholarly and vernacular works by examining the arrival of the Lebanese, their patterns of settlement, and the growth of their communities, while also demonstrating how academic studies of these populations developed alongside the accounts of Lebanese migrant authors and travel writers. It identifies three genres of scholarly analysis. The first focused on the Lebanese as “middlemen” in the colonial and early independence eras. The second inserted the migrants in discourses of dependency and underdevelopment during the Cold War period. The third, contemporary trend contemplates the migrants’ roles in globalizing forms of religious and national identity on one hand and the history and historiography of empire on the other. Recent works have further repositioned the story of West Africa’s Lebanese in ways that show how the migrants and their descendants reasserted their ties to their ancestral “homeland” while redefining what it meant to be Lebanese from diasporic perspectives. Ultimately, scholarship on the Lebanese of West Africa represents a case study of the evolution of historical and social scientific deliberations on “strangers” in colonial and postcolonial societies. Periodizing this body of work demonstrates how theoretical constructs of race, religion, belonging, and identity have evolved in tandem with the historical unfolding of colonialism, decolonization, and nationalism in West Africa.

Published: May 2018

OBJECTIVE

Craniectomy is a common neurosurgical procedure that reduces intracranial pressure, but survival necessitates cranioplasty at a later stage, after recovery from the primary insult. Complications such as infection and resorption of the autologous bone flap are common. The risk factors for complications and subsequent bone flap removal are unclear. The aim of this multicenter, retrospective study was to evaluate the factors affecting the outcome of primary autologous cranioplasty, with special emphasis on bone flap resorption.

METHODS

The authors identified all patients who underwent primary autologous cranioplasty at 3 tertiary-level university hospitals between 2002 and 2015. Patients underwent follow-up until bone flap removal, death, or December 31, 2015.

RESULTS

The cohort comprised 207 patients with a mean follow-up period of 3.7 years (SD 2.7 years). The overall complication rate was 39.6% (82/207), the bone flap removal rate was 19.3% (40/207), and 11 patients (5.3%) died during the follow-up period. Smoking (OR 3.23, 95% CI 1.50–6.95; p = 0.003) and age younger than 45 years (OR 2.29, 95% CI 1.07–4.89; p = 0.032) were found to independently predict subsequent autograft removal, while age younger than 30 years was found to independently predict clinically relevant bone flap resorption (OR 4.59, 95% CI 1.15–18.34; p = 0.03). The interval between craniectomy and cranioplasty was not found to predict either bone flap removal or resorption.

CONCLUSIONS

In this large, multicenter cohort of patients with autologous cranioplasty, smoking and younger age predicted complications leading to bone flap removal. Very young age predicted bone flap resorption. The authors recommend that physicians extensively inform their patients of the pronounced risks of smoking before cranioplasty.
Measuring compliance with minimum wages
Authors: Ritchie Felix , Veliziotis Michail , Drew Hilary , Whittard Damian
Published: May 2018

Identifying genuine underpayment of minimum wages is not straightforward. Some well-known statistical issues affect the measurement of compliance rates, but factors such as processing or behavioural influences amongst respondents can also have an impact. We study the quantitative measurement of non-compliance with the minimum wage, using UK apprentices (who have particularly high non-compliance rates) as a case study. We show that understanding the institutional and behavioural context can be invaluable, as can triangulation of different sources. While the binary nature of compliance makes such problems easier to identify and evaluate, this analysis holds wider lessons for the understanding of the characteristics of large and complex datasets.
Children’s meals at restaurants in Abu Dhabi, United Arab Emirates, have poor nutritional quality
Authors: Garemo Malin , Al Naimi Afnan
Published: May 2018

BACKGROUND: Many people in the UAE eat out frequently, but there is limited knowledge about the nutritional quality of the consumed meals. OBJECTIVE: The aim of this study was to assess the nutritional quality of children’s meals in Abu Dhabi restaurants, considering deep-frying and food group content. METHODS: In this cross-sectional pilot study, popular food outlets were identified using an online customer rating application. Children menus were collected and the meal quality was assessed. A healthy meal should not be deep-fried and contain at least 2 of the following food groups: low-fat dairy/lean protein/whole grain/fruits/vegetables (criteria adapted from the “Kids Live Well Nutritional Criteria” by the National Restaurant Association, US). RESULTS: 58 restaurants were included, of which 29 had children menus, offering a total of 209 meals. 60% of the meals had beverages included in the price: 13% being water or milk. Overall, 78.9% of the assessed meals did not meet the cut-offs for healthy meals. CONCLUSIONS: In this pilot study, a majority of children’s meals in Abu Dhabi’s food outlets had poor nutritional quality. The findings suggest a need for more extensive studies around meal offerings at restaurants.

Published: May 2018

BACKGROUND: One of the objectives of food industry is to seek new resources of oil that preferably presents nutritional values. For human health, fats and particularly vegetable oils are considered as an important source of energy when glucose is not available. In addition, the search for effective, natural compounds with antioxidant activity has been intensified in recent years to replace the synthetic products. OBJECTIVE: The aim of the present work was to determine the fatty acids profile (and variability) of the lipid fractions extracted from five different populations of the leaves of Pistacia lentiscus L. growing in Algeria. In addition, the antioxidant activities of the lipidic fractions were also determined. METHODS: The chemical compositions of tocopherols were also analyzed by HPLC for the first time for this plant part. The chemical percentage variability (presence of two main distinguished clusters) of the fatty acids was discussed using statistical analysis methods (Agglomerative Hierarchical Clustering “AHC” and principal component analysis “PCA”). The antioxidant activity of the dewaxed lipid fractions were investigated in vitro using two different assays: DPPH (1,1-diphenyl, 2-picrylhydrazyl) free radicals scavenging activity and β-carotene bleaching test. RESULTS: For the overall samples, the main saturated fatty acids components were capric acid (C10:0 = 2.49–13.88%), myristic acid (C14:0 = 4.71–9.12%) and palmitic acid (C16:0 = 5.31–9.03%). Alternatively, the main unsaturated fatty acids were oleic acid (C18:1w9 = 3.42–4.85%), linoleic acid (C18:2w6 = 10.94–16.99%) and most importantly α-linolenic acid (C18:3w3 = 20.92–48.92%), which is known for its multiple dietary, pharmaceutical and clinical benefits. CONCLUSION: The results of fatty acids methyl esters identification using GC and GC-MS showed a clear variability in the composition of fatty acids. The main result of this study illustrate the nutritional potential (richness in MUFA such as C18:1w9, presence of essential fatty acids such as C18:2w6 at all the stages of maturation, richness in omega-3 fatty acids such as C18:3w3. of the oil of P. lentiscus leaves, which can provide opportunities for rational exploitation for medicinal purposes and in the food industries. Regarding tocopherols HPLC analysis, the samples were rich in α-tocopherol (58.51–89.17% of the total tocopherols identified). Finally, and for antioxidant activity measured by β-carotene assay, the obtained values suggested good antioxidant activities when compared with antioxidants of reference.

Published: May 2018

BACKGROUND:

Time restricted feeding decreases energy intake without calorie counting and may be a viable option for weight loss. However, the effect of this diet on body weight in obese subjects has never been examined.

OBJECTIVE:

This study investigated the effects of 8-h time restricted feeding on body weight and metabolic disease risk factors in obese adults.

DESIGN:

Obese subjects ( n = 23) participated in an 8-h time restricted feeding intervention (ad libitum feeding between 10:00 to 18:00 h, water fasting between 18:00 to 10:00 h) for 12 weeks. Weight loss and other outcomes were compared to a matched historical control group ( n = 23).

RESULTS:

Body weight and energy intake decreased in the time restricted group (–2.6% ± 0.5; –341 ± 53 kcal/d) relative to controls over 12 weeks ( P < 0.05). Systolic blood pressure decreased in the time restricted feeding group (–7 ± 2 mm Hg) versus controls ( P < 0.05). Fat mass, lean mass, visceral fat mass, diastolic blood pressure, LDL cholesterol, HDL cholesterol, triglycerides, fasting glucose, fasting insulin, HOMA-IR, and homocysteine were not significantly different from controls after 12 weeks (no group×time interaction).

CONCLUSION:

These findings suggest that 8-h time restricted feeding produces mild caloric restriction and weight loss, without calorie counting. It may also offer clinical benefits by reducing blood pressure.
Practice effects in nutrition intervention studies with repeated cognitive testing
Authors: Bell Lynne , Lamport Daniel J. , Field David T. , Butler Laurie T. , Williams Claire M.
Published: May 2018

BACKGROUND:

There is growing interest in the use of nutrition interventions to improve cognitive function. To determine intervention efficacy, repeated cognitive testing is often required. However, performance on tasks can improve through practice, irrespective of any intervention.

OBJECTIVE:

This study investigated practice effects for commonly used cognitive tasks (immediate and delayed recall, serial subtractions, Stroop and the Sternberg task) to identify appropriate methodology for minimising their impact on nutrition intervention outcomes.

METHODS:

Twenty-nine healthy young adults completed six repetitions of the cognitive battery (two sessions on each of three separate visits). Subjective measures of mood, motivation and task difficulty were also recorded at each repetition.

RESULTS:

Significant practice effects were apparent for all tasks investigated and were attenuated, but not fully eliminated, at later visits compared with the earlier visits. Motivation predicted cognitive performance for the tasks rated most difficult by participants (serial 7s, immediate and delayed recall). While increases in mental fatigue and corresponding decreases in positive mood were observed between test sessions occurring on the same day, there were no negative consequences of long term testing on mood across the duration of the study.

CONCLUSION:

Practice effects were evident for all investigated cognitive tasks, with strongest effects apparent between visits one and two. Methodological recommendations to reduce the impact of practice on the statistical power of future intervention studies have been made, including the use of alternate task forms at each repetition and the provision of a familiarisation visit on a separate day prior to data collection.

Authors: Xu Wenbin , Xia Hong , Liu Wei , Zheng Weiying , Hua Lin
Published: May 2018

BACKGROUND AND OBJECTIVE:

Muscle-invasive bladder cancers (MIBCs) are heterogeneous cancers and can be grouped into basal-like and luminal subtypes that are highly reminiscent of those found in breast cancer. Like basal-like breast cancers, basal-like MIBCs are associated with advanced stage and metastatic disease. However, the biological and clinical significance of molecular subtypes of MIBCs remain unclear. Therefore, we implemented a serious of bioinformatics methods to explore genetic similarities between bladder and breast cancers.

METHODS AND RESULTS:

In the current study, by the application of multiple levels data analysis including random forest analysis, PPI and transcription factor regulation network construction, Gene Ontology (GO) and KEGG pathway enrichment analysis, we explored the genetics commonness between MIBC and breast cancers from the molecular heterogeneity based on the disease subtypes.

CONCLUSIONS:

Our study identified some basal-related and luminal-related genes shared by two cancers. These studies can help shed light on the potential relationships between MIBC and breast cancer as a whole.

The specific factors of four common diabetic complications were selected from the biochemical indexes to provide a reference direction for further research.
Multi-subject subspace alignment for non-stationary EEG-based emotion recognition
Authors: Chai Xin , Wang Qisong , Zhao Yongping , Liu Xin , Liu Dan , Bai Ou
Published: May 2018

Emotion recognition based on EEG signals is a critical component in Human-Machine collaborative environments and psychiatric health diagnoses. However, EEG patterns have been found to vary across subjects due to user fatigue, different electrode placements, and varying impedances, etc. This problem renders the performance of EEG-based emotion recognition highly specific to subjects, requiring time-consuming individual calibration sessions to adapt an emotion recognition system to new subjects. Recently, domain adaptation (DA) strategies have achieved a great deal success in dealing with inter-subject adaptation. However, most of them can only adapt one subject to another subject, which limits their applicability in real-world scenarios. To alleviate this issue, a novel unsupervised DA strategy called Multi-Subject Subspace Alignment (MSSA) is proposed in this paper, which takes advantage of subspace alignment solution and multi-subject information in a unified framework to build personalized models without user-specific labeled data. Experiments on a public EEG dataset known as SEED verify the effectiveness and superiority of MSSA over other state of the art methods for dealing with multi-subject scenarios.

Published: May 2018

During the past two decades, tissue elasticity has been extensively studied and has been used in clinical disease diagnosis. But biological soft tissues are viscoelastic in nature. Therefore, they should be simultaneously characterized in terms of elasticity and viscosity. In addition, the mechanical properties of soft tissues are temperature dependent. However, how the temperature influences the shear wave dispersion and the viscoelasticity of soft tissue are still unclear. The aim of this study is to compare viscoelasticity of fat emulsion phantom with different temperature using acoustic radiation force elasticity imaging method. In our experiment, we produced four proportions of ultrasonic phantom by adding fat emulsion gelatin. Through adjusting the component of the fat emulsion, we change the viscoelasticity of the ultrasonic phantom. We used verasonics system to gather data and voigt model to fit the elasticity and viscosity value of the ultrasonic phantom we made. The influence of temperature to the ultrasonic phantom also measured in our study. The results show that the addition of fat emulsion to the phantom can increase the viscosity of the phantom, and the shear wave phase velocity decreases gradually at each frequency with the temperature increases, which provides a new material for the production of viscoelastic phantom.

Authors: Sohn Jeehoon , Park Sung-Ha , Kim Sukwon
Published: May 2018

BACKGROUND:

Dancesport is a popular activity among older adults who look for fun and fitness in Korea. Studies reported positive sociological and psychological effects of dancesport. But, little studies were performed to evaluate the effects of dancesport on balance performances.

OBJECTIVE:

The objective of the present study was to evaluate the effects of dancesport for 15 weeks on walking balance and standing balance of older adults.

METHODS:

Older adults regularly participated in the dancesport program 3 times a week for 15 weeks. The program included Rumba, Cha-cha-cha, and Jive. They exercised the prescribed dancesport at intermediate level for 50–60 mins for each time. A total 22 reflective markers were placed on the anatomical landmarks and 8 cameras were used to measure 3-D positions of participants. Also, center of pressure (COP) data were measured to analyze standing balance using a ground reaction board at 1200 Hz for 30 seconds. One-way analysis of variance (ANOVA) was performed to test the effects of 15 weeks of dancesport on walking balance and standing balance.

RESULTS:

The results suggested that, after 15 weeks of dancesport participation, older adults’ walking balance (48.3 [Formula: see text] 20.3 cm[Formula: see text] vs 38.2 [Formula: see text] 18.2 cm[Formula: see text]) and standing balance (COP area: 189.4 [Formula: see text] 85.4 mm[Formula: see text] vs 103.5 [Formula: see text] 55.4mm[Formula: see text], COP distance: 84.2 [Formula: see text] 34.4 cm vs 76.5 [Formula: see text] 21.4 cm) were significantly improved.

CONCLUSION:

Performing dancesport would require moving center of mass rapidly and frequently while maintaining posture. This may result in improving walking balance and standing balance in the present study. The study concluded that dancesport would be an effective exercise method in enhancing postural stability of older adults.

Authors: Li Mi , Xu Hongpei , Liu Xingwang , Lu Shengfu
Published: May 2018

BACKGROUND:

Many studies have been done on the emotion recognition based on multi-channel electroencephalogram (EEG) signals.

OBJECTIVE:

This paper explores the influence of the emotion recognition accuracy of EEG signals in different frequency bands and different number of channels.

METHODS:

We classified the emotional states in the valence and arousal dimensions using different combinations of EEG channels. Firstly, DEAP default preprocessed data were normalized. Next, EEG signals were divided into four frequency bands using discrete wavelet transform, and entropy and energy were calculated as features of K-nearest neighbor Classifier.

RESULTS:

The classification accuracies of the 10, 14, 18 and 32 EEG channels based on the Gamma frequency band were 89.54%, 92.28%, 93.72% and 95.70% in the valence dimension and 89.81%, 92.24%, 93.69% and 95.69% in the arousal dimension. As the number of channels increases, the classification accuracy of emotional states also increases, the classification accuracy of the gamma frequency band is greater than that of the beta frequency band followed by the alpha and theta frequency bands.

CONCLUSIONS:

This paper provided better frequency bands and channels reference for emotion recognition based on EEG.
