Graphical User Interface for educational content programming with social robots activities and how teachers may perceive it

Interactive devices have been successfully applied in education in the last decades. The most used devices for such tasks are personal computers and tablets, due to its financial trade-off and popularization. Social robots are less used, mainly because of its cost and the complexity of being programmed. In this paper, a solution to work around the complexity of programming social robots is presented as a Graphical User Interface (GUI). The GUI system controls an interactive robot which plays with the students and adapts its behavior autonomously. During the activity execution, the adaptive algorithm detects student's body signals and verbal responses to adapt the addressed content to harder or easier questions. After creating and running an activity, all sessions' evaluation and information can be accessed for visual analysis, as well as students' preferences throughout the interaction. The proposal was presented to regular teachers from the elementary school that answered a questionnaire about their perception about the proposal. The answers were analyzed and, in general, they seemed to slightly notice the system potential in and how it can support them in after-classes exercises, despite it require some time to fully get used with the interface.
GAMOS DICOM Simulation on Occupational EL Dose due to 99mTc and 131I
Exposures in Nuclear Medicine Departments

Radiation induced cataracts is a disease that is common amongst radiation exposed staff. About 30 percent of retired occupational radiation workers developed eye lens (EL) cataracts. Epidemiological studies on radiation therapy patients, occupational workers, and atomic bomb survivors show that 0.5 Gy of acute or fractioned radiation dose to EL causes one or both lens to cloud. The annual EL dose limit drawn by the International Commission for Radiation Protection (ICRP) was 150 mSv and was changed in 2012 to 20 mSv averaged over 5 years, with no single year exceeding 50 mSv. The limited number of researche done in Nuclear Medicine (NM) clinics with the Hp(3) dosimeters suggest that the annual EL dose from three procedures is measured to be between 4.5 and 9 mSv (i.e. dispensing, preparing and administering). These procedures are performed when the radioactive materials are in closed shielded containers or behind a barrier. Common radioactive material handled by occupational workers in NM clinics are 99mTc and 131I. They pose less radiation hazard to workers EL in the three procedures when they are behind shielded containers. Moreover, once the radioactive material is administered into patients, they become open sources and pose more radiation hazard to workers. The Hp(3) dosimeter is a new uncommon dosimeter. Many radiation facilities use the Hp(0.07) and Hp(10) dosimeters coupled with many conditions and conversion factors to find approximate results. Therefore, simulations are performed to find the EL dose. However, some simulations are performed with little flexibility in simulation geometry, others utilize low-quality phantoms or present the simulation results in terms of fluxes or energy ranges. In the present study, the NM worker EL dose is simulated by utilizing a high-resolution Digital Imagning Communication in Medicine (DICOM) image in GEANT4 Archeticture for Medical Oriented Simulation (GAMOS). A water cylinder homogenously filled by radioactive material, representing the administered patient, was created in the simulation. The worker exposure scenario was simulated by placing the cylinder in three different directions and five different distances with respect to the DICOM image. The results of the simulation reveal that the highest occupational EL radiation dose is received from the anterior-posterior direction, followed by the lateral, and the posterior-anterior directions. The results of the conservative simulated scenario reveal that the worker EL dose is exposed to three tenths of the annual dose limit after 110 131I patients, or 300 99mTc patients.
NOISE REDUCTION IN CDMA SYSTEM USING SOFT HANDOVER

Mobile cellular communication becomes more and more important in today's communication. In cellular network, the radio and fixed links required are not permanently allocated for the duration of a call . The function of the handover is to make an on going call to different cell or channel. Also it maintains a call in progress across cell boundaries in mobile communication. ESTI (European Telecommunications standards Institute) adopted Wideband code division multiple access as the mainstream air interface solution for the third-generation networks to provide a multitude of services, especially multimedia and high –bit-rate packet data. In this paper the soft/softer handover and hard handover for voice and packet data in WCDMA systems are presented. Hard handover is necessary in WCDMA and will be presented in this paper. Softer handover is implemented within one base station between different sectors; it doesn't cause the system load increase as implemented with in the base station. The implementation of soft handover can increase the coverage, capacity performance or balance the network load. Important parameters such as, adding threshold, dropping threshold and timer-to-dropping will be analyzed.
EFFECT OF USING DISCARDED DATES ON PRODUCTIVE AND REPRODUCTIVE PERFORMANCE OF LACTATING FRIESIAN COWS

Twenty lactating Friesian cows with average live body weight of 550 ±18 kg in their the 2nd to 5th parity were used to study the effect of replacing yellow corn grains )YCG) by discarded dates (DD) in concentrate feed mixture (CFM) at levels of 0, 33, 66, and 100% (w/w), on their productive and reproductive performance. Cows were assigned randomly to four similar groups (5 in each) according to milk yield, parity and live body weight (LBW). The levels of replacement of YCG by DD in CFM were0, 33, 66, and 100% (w/w) for G1 (control), G2, G3 and G4 as tested rations, respectively. Results showed that the contents of OM, CP and NFE were higher in YCG- compared to DD-ration, however the content of CF and ash showed an opposite trend. Cows in G3 (66% DD) recorded the highest (P<0.05) digestibility coefficients of all nutrients, nutritive values and the intake of DM, TDN and DCP, followed by G2 and G4, while G1 (control) almost had the lowest values. The pH value in rumen liquor markedly decreased after feeding and its values 3 h after feeding were lower (P<0.05) with the DD-rations than control. The highest TVFA’s concentration in rumen liquor was recorded with in G3 after feeding, while the lowest concentration was found in G1 after feeding. Ammonia-nitrogen concentration in G3 was higher before and after feeding than the other treatments. Cows in G3 had the highest concentrations of total proteins, globulin and glucose and the lowest concentrations of albumin and total lipids in blood plasma. Yield as actual milk and 4% FCM were higher (P<0.05) for DD-rations than those of control, being the highest in G3. Cows in G3 recorded the highest (P<0.05) percentages of fat, protein, and total solids in milk. Cows in G3 showed the best feed efficiency (DM, TDN and DCP: 4% FCM) compared with those fed the other rations (P<0.05). Average daily feed cost was higher (P<0.05)in G2 and G3 as compared to G1 and G4. While, cows in G3 showed the lowest feed cost/ kg 4% FCM and the best economic efficiency followed by G4 and G2, while G1 had the opposite trends. Cows in G3 had the best of most reproductive traits as first estrus, first service, service period, number of service /conception and conception rate. It could be concluded that partial replacement of yellow corn grains by discarded dates at the level of 66% as a source of energy in concentrate feed mixture improved the feed intake, digestibility, rumen fermentation activity, yield and composition of milk, economic feed efficiency as well as the post-partum reproductive traits in Friesian cows.
The Impacts Of Presentation Modes And Product Involvements On “Line” Short Message Service (SMS) Advertising Effectiveness

In today’s ubiquitous commerce (UC) era, short message service (SMS) advertisement has played an important role in the world of marketing. Convenience and economical reasons influence SMS usage frequency along with social involvement to influence attitudes towards SMS advertising. SMS advertising creates numerous opportunities for the marketers in promoting their products effectively. Adopting the competition for attention theory as the theoretical framework, we developed hypotheses to investigate the influences of presentation mode and involvement on SMS advertising performance (recall of advertising information). An experiment was conducted to examine the effects of three types of information presentation modes (text-only, image-text, and emoji-text) in the contexts of two product types (highversus low-involvement products) in the “LINE” SMS environment. Specifically, in this current study, we allocate participants to six experimental environments (text-only for high-involvement products, text-only for low-involvement products, image-text for high-involvement products, image-text for low-involvement products, emoji-text for high-involvement products and emoji-text for low-involvement products) randomly to collected empirical data to examine the proposed hypotheses. The research findings are expected to provide instrumental guidelines for the practitioners to better achieve the goals of ads in the “LINE” SMS environment. Also, the empirical results may provide insights into the research of advertising interface design of SMS and integrating efforts from cognitive science and vision research to understand users’ involvement of SMS advertising processes.
Method Development and Validation for Estimation of Dalfampridine in Synthetic Mixture by using UV Spectrophotometry and RP-HPLC

An accurate, precise and reproducible UV-spectrophotometric and liquid chromatographic assay method were developed and validated for the determination of dalfampridine in synthetic mixture form. Spectrophotometric estimation was done by calibration curve method using 0.1 N NaOH as solvent. In this method λmax for dalfampridine was selected at 244 nm. Different analytical performance parameters such as linearity, precision, accuracy, specificity, limit of detection (LOD) and limit of quantification (LOQ) were determined according to International Conference on Harmonization ICH Q2B guidelines. The RP-HPLC method was developed by the isocratic technique on a reversedphase Thermo C18 (250 × 4.6 mm, 5μm) column with mobile phase consisting of methanol: acetonitrile (50:50v/v) at flow rate of 1.0 ml/min. The retention time for dalfampridine was 4.186+0.3 min. The linearity range for dalfampridine was 5-25 μg/ml for both HPLC and UV method. The linearity of the calibration curves for each analyte in the desired concentration range was good (r >0.999) by both the HPLC and UV methods. The method showed good reproducibility and recovery with percent relative standard deviation less than 2%. Moreover, the accuracy and precision obtained with HPLC co-related well with the UV method which implied that UV spectroscopy can be a cheap, reliable and less time consuming alternative for chromatographic analysis. The proposed methods are highly sensitive, precise and accurate and hence successfully applied for determining the assay and in vitro dissolution of a marketed formulation.
Modeling and forecasting complex patterns of mineral production. Gold mining in Canada

Abstract The complex pattern of gold production in Canada, which differs from the classic Hubbert´s curve, is modeled, and a short-term forecast is made, via the Fundamental Equation of Mineral Production (FEMP). For intervals of time with a variable production to reserves ratio, a discrete piecewise version of the equation updates the reserves and the Production to Reserves Ratio (PRR) by units of time. These piecewise linear portions of the PRR correspond to sub-cycles of rising and declining production embedded in the overall history of production. This version of the FEMP allows modelling of any pattern of mineral production at a universal range of scales. The Hubbert´s linearization indicates the official account of reserves underestimates the real amount of gold resources in Canada. The equivalence between the Hubbert’s formula and the FEMP is introduced. The Hubbert curve is shown as a case study of the Fundamental Equation, featured as the product of a quadratic function of the cumulative production and a rational function of the PRR with time. The forecast for Canada’s current gold production illustrates the metal output is about to peak with an all-time record high in the near future, unless new findings or influential global economic factors are introduced (i.e., a sharp and sustained growth of gold demand from regional markets), allowing an increase of the slope of the linear function featured by the PRR of the FEMP-based model.
ASSESSMENT OF ANTIOXIDANTS BY HPLC-MS IN GRAPEVINE SEEDS

It is well known, that grapevine seeds are rich in significant antioxidants. However, the issue of dealing with the analysis and comparison of antioxidant components in the seeds of Vitis vinifera L. in individual cultivars has not yet been sufficiently studied. The experiment was performed with extracts of three varieties (Blaufränkish, Italian Riesling and Cabernet Moravia) and three interspecific cultivars (Nativa, Marlen and Kofranka).
Assessment of Different Modalities and Their Impact on Patients with Ruptured Intracranial Arteriovenous Malformation Treated in King Abdulaiziz Medical City in Jeddah, Saudi Arabia

Background Intracranial arteriovenous malformation (AVM) is a rare congenital disease that is characterized by an abnormal tangle of blood vessels where arteries abnormally shunt into veins with no intervening capillary bed. Several treatment modalities, such as microsurgical removal, embolization, and stereotactic radiosurgery (SRS), are used to treat AVM either solely or in combination. We aimed to assess and compare the effect, morbidity, and mortality outcomes of mono-treatment with embolization and combined treatment for AVM obliteration. Methodology This retrospective cohort study was conducted in the National Guard Hospital Jeddah and reviewed all the AVM patients that visited the center between 2008 and 2017. We assessed presenting symptoms at diagnosis and any co-morbidities as the clinical characteristics and the patients’ AVM and Spetzler-Martin grade as the morphological characteristics. Moreover, we performed a three-year follow-up on suitable patients and assessed their outcomes using the modified Rankin Scale. In addition, we performed follow-up imaging on the patients to evaluate AVM obliteration after any of the procedures. Results We included 29 patients treated in our hospital (72.4%, males; 27.6%, females; mean age 40 years). About 65% of the patients underwent mono-therapy consisting of one or more embolization sessions while about 34% underwent combined treatment (embolization + surgery or embolization + SRS). We found more cases of complete obliteration among patients who underwent mono-therapy (52.6%) than among those who underwent combined treatment (30%). Patients who underwent mono-therapy showed better outcomes compared to those who underwent combined therapy; however, the difference did not reach statistical significance. Conclusions Embolization mono-therapy appears to be more effective with regards to the obliteration rate and outcome compared to combined therapy with either SRS or surgery in patients treated in our center.
Rethinking the Approach to Gambling Disorder: The Case of the Italian Healthcare Services

In a cultural context where ludopathy is a social phenomenon built through normative and medical definitions, how are healthcare services approaching the treatment of gambling disorder? The purpose of this study is to examine the Italian healthcare service approach to pathological gambling disorder (PGD), with the aim of formulating proposals for action. Italy is chosen as a crucial terrain of investigation to understand the challenges posed by the growth of the gambling market in Europe and its consequences on its healthcare systems. The empirical material underpinning the analysis includes the latest official statistical data regarding the socio-medical treatment of people with addictions in Italy as well as qualitative interviews conducted with social-sanitary structure managers responsible for therapeutic activities combating dependencies. Through a social construction perspective, gambling and PGD are understood as social phenomena whose meaning and definition comes as a result of a process of negotiation. Ac cordingly, principal findings are related to the respondents’ visions of PGD and how they perceive the activities of social and health services, the impact of changes in legislation on the organisation of services, and the ongoing changes regarding this process. An agenda of interventions, based on the experience of professional involved in treatment, is necessary to rethink the approach to PGD.
INVESTIGATION OF THE ELECTROPHYSIOLOGICAL PROPERTIES OF THE MAJOR CELL TYPES IN THE RAT OLFACTORY TUBERCLE

by ELIZABETH CHEN CHIANG Olfactory information is processed by a diverse group of interconnected forebrain regions. Most efforts to define the cellular mechanisms involved in processing olfactory information have been focused on understanding the function of the olfactory bulb, the primary second-order olfactory region, and its principal target, the piriform cortex. However, the olfactory bulb also projects to other targets, including the rarely-studied olfactory tubercle, a ventral brain region recently implicated in regulating cocaine-related reward behavior. We used whole-cell patch clamp recordings from rat tubercle slices to define the intrinsic properties of neurons in the dense and multiform cell layers. We find three common firing modes of tubercle neurons: regular-spiking, intermittent-discharging and bursting. Regular-spiking neurons are typically spiny-dense-cell-layer cells with pyramidal-shaped, dendritic arborizations. Intermittently-discharging and bursting neurons comprise the majority of the deeper multiform layer and share a common morphology: multipolar, sparsely-spiny cells. Rather than generating all-or-none stereotyped discharges, as observed in many brain areas, bursting cells in the tubercle generate depolarizing plateau potentials that trigger graded but time-limited intermittent discharges. We find two distinct subclasses of bursting cells that respond similarly to
CONSTRUCTION OF A HIGH-ACCURACY POINT CLOUD MAP FOR THE AUTOMATIC DRIVING OF AN ELECTRIC WHEELCHAIR

The proportion of elderly people in traffic accidents is increasing in Japan. It is therefore necessary to make transportation for the elderly safer by automating the electric wheelchair. Technologies that estimate the vehicle position and orientation are required to realize automated driving. One technology is simultaneous localization and mapping. This technology computes the current self-position by comparing a map and data from a sensor. The present study used the normal distributions transform algorithm for self-position estimation. The main aim of the study was to construct a threedimensional map required for self-position estimation on a sidewalk. For the evaluation of this map, self-position estimation was performed using the map and estimated distances were compared with actual distances measured, by a laser range finder. Results show a difference between the actual position and estimated position of approximately 0.05 m in the area of a sidewalk. The selfposition estimation on the sidewalk using the normal distributions transform was thus accurate. Future work will focus on a next-generation map that contains point data for the upper part of a building.
Hardware Design and Evaluation of Cell Allocation Cache

Multi-core processors are widely used to improve performance of computer systems. To achieve both high per- formance and low power consumption, many researches from device level to processor architecture or application software level have been done. This paper focuses to cache system which is one of the significant module consuming large power. To achieve both high performance and low power consumption, Cell Allocation Cache is proposed which is similar to dynamic cache partitioning technique, but it allocates cache spaces called “Cell” which is smaller than a way. Cell Allocation Cache can achieve better performance than normal cache and cache partitioning. The previous research evaluates the performance of the Cell Allocation Cache. However, circuit scale has not been clarified because detailed design is not performed. This paper evaluates circuit scale of Cell Allocation Cache and shows the hardware overhead.
PCR-RFLP Based Screening of Frankia in Alder Nodules Having Different Levels of Nitrogenase Activity

One hundred and thirty nodules from 13 different A/nus nepalensis trees from a site in Shillong, India, were screened for nitrogenase activity. Nodules from different trees were found to differ in nitrogenase activity estimates obtained by acetylene reduction assay. In order to analyze whether the differences in nitrogenase activities were due todifferent Frankia strains residing in the nodules, nodule DNA were subjected to a Polymerase Chain Reaction Restriction Fragment Length Poly-morphism (PCR-RFLP) study. High and low activity nodules from different trees were found to contain Frankia belonging to similar PCR-RFLP groups. Therefore, the host plant appears to exert a considerable influence on the nitrogen fixation rates of Frankia nodules.
SIMULATIONS OF THE SMOKE PARTICLE IMPACT DETECTOR(SPID) AND OBSERVATIONS DURING THE G-CHASER ROCKET CAMPAIGN

SPID, Smoke Particle Impact Detector, is a Faraday cup detector designed to measure nanometer-sized meteoric smoke particles during rocket flights. We report measurements made with SPID during the G-Chaser student rocket campaign 13 January 2019 and describe the design of the SPID instruments. Model calculations of dust trajectories within the detector result in an effective crosssection of 0.97 for particles larger than 0.5 nm at 60 km. Data analysis indicates that in order to generate the measured current, the number densities must be ∼ 1010m−3 or higher at 60 km. During the campaign the ground systems MAARSY and EISCAT were operating. These ground measurements showed smooth ionospheric conditions with weak precipitation down to 90 km. As a secondary goal of the campaign we wanted to investigate the possible connection between PMWE and MSPs. On the day of the launch there was no sign of PMWE and no conclusions can be drawn at this point.
Performance Evaluation of Heterogeneous Sensor Networks with ATPC and Load Balancing

Wireless Sensor Networks (WSNs) are battery-powered ad-hoc networks in which sensor nodes are scattered over a region. These networks have high node density but highly resourceconstraint in terms of size, power and bandwidth. Most of the existing sensor networks focus on homogeneous sensor networks, but these networks have poor performance in terms of energy consumption and network life time. So it is required to analyse the heterogeneous sensor network (HSN) model for better performance. Adjusting the transmission power of each node instead of using same power level to all nodes is the method used in HSN to reduce energy consumption. HSN with adaptive transmission power control (ATPC) of low-end sensors are analysed in terms of energy consumption and network life time and compared it with HSN without power control. But ununiform load distribution has been taken place. In this paper, Load balancing is also applied over HSN with ATPC and it is compared with HSN with ATPC. Simulation results prove that heterogeneous sensor networks with ATPC and Load balancing outperform the heterogeneous sensor networks with ATPC alone in terms of energy consumption and network life time.
