Authors: Komalasari Ema , Widiawati Dina
Published: April 2020

Abstrak -  Makanan jajanan dikonsumsi oleh sekitar 2,5 miliar orang diseluruh dunia setiap harinya. Namun, pengetahuan pedagang tentang keamanan makanan masih rendah dan memberikan risiko keamanan pangan. Penelitian ini bertujuan untuk menentukan tingkat kepatuhan pedagang makanan pada cara produksi pangan yang baik (CPPB). Survei dirancang untuk 50 pedagang kaki lima berdasarkan 7 elemen, yaitu lokasi, peralatan, penggunaan air, perilaku pedagang, proses, sistem penyimpanan, dan pengelolaan limbah. Sebanyak 62% pedagang menjual makanan ringan atau makanan tradisional, 32% pedagang menjual minuman, dan 6% menjual produk non-makanan. Semua penjual minuman berstatus cukup patuh terhadap CPPB. Sebanyak 33,33% dari penjual makanan ringan atau makanan tradisional tidak mematuhi CPPB, dengan 17,64% dari pedagang tidak mematuhi CPPB meskipun mereka telah mengikuti pelatihan keamanan makanan sebelumnya. Sebagian besar titik kritis disebabkan oleh sistem penyimpanan yang buruk, peralatan kotor, perilaku penjual yang buruk, dan proses pengolahan yang buruk.

Abstract - Street foods are consumed by around 2,5billion people around the world every day. However, the vendor’s knowledge about food safety is still low and givefood safety risk. The study was aimed to determine the level of compliance food vendors on the implementation of good manufacturing practices. A survey was designed to 50 street vendors based on 7 elements, which were location, equipment, water usage, vendors’ behavior, process, storage system, and waste management. The vendors were 62% selling a snack or traditional food, 32% selling beverages, and 6% selling non-food products. All beverages vendors had the status of quite obedient to GMP. As many as 33,33% of snack or traditional food vendors were not compliant with GMP, with 17,64% of vendors having not compliant withGMP even though they had attended food safety training before. Most of the critical missing points were caused by the poor storage system, dirty equipment, poor vendors' behavior, and poor processing process.

Published: April 2020

W artykule zrekonstruowano przebieg współpracy Konstantego I. Gałczyńskiego z tygodnikiem „Prosto z Mostu”, wychodzącym w latach 1935–1939. Poczyniono ustalenia bibliograficzne. Ze szczególną uwagą uwzględniono listy poety, opublikowane na łamach wspomnianego tygodnika. Przedstawiona epistolografia nie była dotychczas badana i przedrukowywana. Miniatury listowe odznaczają się językową pomysłowością, poliglotyzmem i erudycją. Gałczyński zgłasza swoje sprawy osobiste w kontekście kwestii rangi wyższej, społecznej, a nawet narodowej i państwowej – albo odwrotnie. Autor przedstawia siebie jako człowieka ideowego, pryncypialnego i odpowiedzialnego nie tylko za dobro własne, ale także żartuje, polemizuje, parodiuje. Treść listów wnosi pewną wiedzę o biografii Gałczyńskiego i jego poglądach (na przykład o relacjach polsko-żydowskich), a także świadczy o jego umiejętności kreowania własnego wizerunku i wpływania na odbiór własnej twórczości. Artykuł uzupełnia aneks, w którym podane są opracowane krytycznie omawiane listy, a także zapomniane minirecenzje Gałczyńskiego, opublikowane w ankiecie „Prosto z Mostu”: "Jaką najciekawszą książkę przeczytałem".
"Zawisza Czarny" Juliusza Słowackiego - dramat w rozsypce
Authors: Dybizbański Marek
Published: April 2020

Marek Dybizbański w swoim artykule zatytułowanym "Zawisza Czarny" Juliusza Słowackiego w rozsypce dowodzi między innymi, że tekst polskiego wieszcza zachował się w postaci różnorodnej zbieraniny, w której spotykają się rozwiązania wzajemnie sprzeczne oraz nakładają się na siebie alternatywne opracowania, tylko dlatego, że Słowacki ostatecznie nie napisał dramatu, to jest: nie doprowadził go do postaci skończonej, która uzyskałaby autorską pieczątkę, najlepiej w postaci autoryzowanego wydania. Po śmierci poety inicjatywę przejęli badacze rękopisu, edytorzy, jak też historycy literatury, pracujący według współczesnych sobie standardów, które tymczasem podlegały powolnej ewolucji, wskutek czego "Zawisza Czarny" przeszedł już w dziejach swej krytycznej recepcji przez kilka rozmaicie ukierunkowanych faz. Badacz konkluduje, że próba znalezienia sposobu na wydanie tekstu "Zawiszy Czarnego", które umożliwi wielokierunkową lekturę tekstu przecież „rozsypanego”, wiedzie nieuchronnie ku edycji genetycznej.

Conducting research activities is one of the competencies that should be owned by a professional teacher, this is because one of the characteristics of an effective teacher is a teacher who has a reflective nature. Classroom action research (CAR) is now one of the efforts to solve problems and improve the quality of learning that can be done by teachers in their classrooms. In the implementation of the service, the service division divides the activity method into three stages which include the planning stage, the organizing stage, the workshop implementation stage, and the evaluation phase. The training participants consisted of 14 teachers from various subject areas at MTs Negeri 6 Tulungagung. Implementation of assistance to better understand the concepts and applications of classroom action research (CAR) is carried out by lecturing, discussion and question and answer methods. The enthusiasm of the participants in asking questions was very good, it was proven that there were more than half of the participants asking questions related to CAR. While the implementation of mentoring to write a class action research report (CAR) in the form of scientific journal articles begins with a workshop on writing narrative learning in class as a form of CAR analysis, online search tracing and reference downloads, and concludes with a workshop on journal article writing based on CAR activities participants have ever carried out.

Authors: Miritoiu Cosmin Mihai , Stănescu Marius Marinel , Bolcu Dumitru
Published: April 2020

The paper presents the mechanical behaviour and properties of a new hybrid vegetal based resin. For this, through static loading tests, the main mechanical characteristics were determined: static Young modulus, breaking strength, breaking elongation and transversal Poisson ratio. Samples of the proposed materials were subjected also to free vibration tests, by clamping them at one end and leaving them free at the other. The observation and results from these were used for deduction of the first vibration mode eigenfrequency, the dynamic Young modulus, the loss and damping factors. Some representative SEM images with an electronic microscope were collected and the samples surface roughness was determined. By using the Thermogravimetric analysis (TGA), the mass loss up to 800� C was investigated. Compared to the other resins that have dammar in composition, the proposed dammar based resin from this research has a 15.32 times higher static Young modulus than the oil palm trunk and 8.885 times higher than the oil palm trunk (OPT) with 20% dammar resin.
New Thermoplastic Damping Polymeric Materials Based on Ethylene-Vinyl Acetate

Published: April 2020

This article is devoted to the problem of working out of damping polymer materials which are effective in the wide temperature and frequency range. In the modern world, work is being carried out to create damping polymer composite materials (DPM) from which it is possible to manufacture protective elements and parts of engineering structures of reduced vibration excitability. Existing DPM have a narrow temperature range, within which effective vibration absorption is observed, moreover, most of them go through a vulcanization stage, which increases the cost of the final product, has a harmful effect on environment and allows limited recycling of waste. One of the ways to solve this problem is to replace traditional rubber vibration-absorbing materials with thermo-elastoplasts (TEP). The most promising polymer for TEP is ethylene vinyl acetate (EVA), which has high damping properties, oil resistance and relative incombustibility. In this regard, experimental studies were conducted to establish the patterns of influence of the type and concentration of structure-forming components (plasticizers, fillers, modifiers) on the dynamic mechanical properties of TEP based on EVA in order to develop a new DPM effective in a wide temperature range. The leading method to investigate this problem is a method of dynamic mechanical analysis which allows to get information about changes of mechanical characteristics under mechanical load and controlled temperature and frequency. With the help of detected patterns it was possible to determine type of plasticizer which significantly decreases glass temperature of EVA. The percentage ratio of EVA/plasticizer system is stated, and the type of plasticizer at which the maximum of mechanical losses takes over greater values is accordingly detected. It is revealed, that to work out DPM on EVA basis, which are effective in wide temperature range it is more preferable to add not less than 40 % on volume basis inert fillers, such as talc or mica with addition of 5-10 % of carbon as the hardening additive. The kind of resin improving damping properties and raising rigidity of composites on EVA basis is defined. On the basis of the research, a material was developed which has the following properties: the maximum value of tan δ is at least 0.45 at a temperature of plus 5�C (oscillation frequency 10 Hz); width of the temperature interval within which tan δ is not less than 0.3 from minus 40 to plus 50�С (oscillation frequency 10 Hz); conditional tensile strength of not less than 10 kg/cm2, cold resistance up to minus 50�C.

Published: April 2020

Carbon fibre reinforced (CFR) laminates were manufactured by prepreg lay-up and deposition of interlaminar carbon nanotubes (CNTs). An easy and innovative manufacturing procedure was used. CNTs were separated in solvent by ultrasonication, and poured on the woven fabric prepreg. Solvent evacuation was performed at low temperature, and dry functionalized prepregs were used for composite lamination. Laminates were cured by compression moulding on a heating plate. Peeling tests, differential scanning calorimetry (DSC), and dynamic mechanical analyses (DMA) were carried out on multiply samples with and without 1 wt% of interlaminar CNTs. Results show that the glass transition temperature of the resin matrix reduces because of the interaction with CNTs. Nevertheless, peeling strength shows 10% increase at room temperature.

Published: April 2020

Molecularly imprinted polymer (MIP) beads for proto-hypericin recognition were prepared by suspension polymerization. In order to study the impact of monomers on the MIPs properties, various monomers such as acrylic acid (AA), hydroxyethyl methacrylate (HEMA), methacrylic acid (MAA) and itaconic acid (IA) in their combinations were crosslinked with ethylene glycol dimethacrylate (EDMA) in the presence of a complex phyto-extract template derived from Hypericum perforatum L. The synthesized MIPs and corresponding non-imprinted polymers NIPs were characterized by infrared spectroscopy analysis, morphology and thermogravimetric analysis. High-performance liquid chromatography combined with UV-Visible spectroscopy, used to investigate the recognition properties of the MIPs for various naphthodianthrones, pointed out that the MIP IA-AA system seemed to be the most adequate for favoring quantitative rebinding of proto-hypericin and proto-pseudohypericin against competitors with similar structures, like hypericin and pseudo-hypericin, which are usually present in high quantities in the primary Hypericum perforatum L. phyto-extracts.

The aim of our study was to evaluate the deformation resistance of two palatal plate type connectors of removable partial dentures and to make a comparison between the reduced palatal plates and the large ones, in terms of bending resistance during function. We tested 10 maxillary class I Kennedy removable partial dentures made for real clinical cases and duplicated their connectors, 5 of each type. A Universal Loading Machine was used to apply a bilateral progressive force to the PM2-M1 area until the samples bended, recording the force value at which the first change occurred. The results were analyzed using the ANOVA method. For the reduced palatal plate group, the minimum bending force value was 1584 N, the maximum bending force value being 2920 N. For the large palatal plate group, the minimum bending force value was 3150 N, the maximum value being 3380 N. Statistical analysis of data using the ANOVA method shows that the results are statistically relevant, with a p value of 0,001031 (p[0,05). The results showed that decreasing the width of the palatal plate can have a significant effect on the deformation resistance of the major connector and can affect its rigidity; in clinical practice, these results can help dentists to use alternative appropriate design methods of increasing the rigidity of reduced palatal plates, in order to protect both the remaining structures and the acrylic components of the dentures during the years of its functioning. Keywords: palatal plate, removable partial denture, deformation resistance

The main purpose of this study is to evaluate three different adhesiveprotocols between two composites. We used 60 composite specimens (Kerr�s Herculite XRV Ultra), randomly divided into 3 equal experimental groups, in which adhesion was performed using different protocols: Group 1 (n= 20) surface preparation with a 1.4 mm cylindrical diamond bur (Kerr Dental, FG503C-5) + etch and rinse technique in 2 steps; Group 2 (n= 20) surface preparation with a 1.4 mm cylindrical diamond bur (Kerr Dental, FG503C-5) + Al2O3 (Zhermack Dental) sandblasting + etch and rinse technique in 2 steps; Group 3 (n= 20) surface preparation with a 1.4 mm cylindrical diamond bur (Kerr Dental, FG503C-5) + glycine (EMS) sandblasting + etch and rinse technique in 2 steps. Adhesion assessment was made by measuring tensile strength with a universal testing machine, the INSTRON 3343 (Instron�, USA). At the end, the results were statistically compared using the ANOVA test. Group 3 (glycine protocol) had the greatest values in terms of tensile strength.

Published: April 2020

The present paper is focused on evaluating the mechanical characterization of dicyclopentadiene (DCPD) and 5-ethylidene-2-norbornene (ENB) healing systems synthetized by in-situ polymerisation. Both healing systems were embedded in glass fibre reinforced polymer (GFRP) composite and subjected to three-point bending test regime. Microstructural and FT-IR analysis showed the formation of microcapsules and a successful integration in the composite material. To observe the influence of temperature variation, some specimens were exposed to thermal cycling (-20oC to +100oC) for 12 hours and tested in the same conditions. It was observed that the addition of microcapsules in the composite material decreased its mechanical properties by 8% and 10% for DCPD system and ENB system respectively. Thermal cycling suggested a drop of 24% on bending strength for DCPD system and 17% for ENB. Resting after 24 hours showed a healing recovery of 74% for DCPD healing system and of 97% for ENB system.

The article presents the results of the study of the ecology of Gentiana oschtenica by population-ontogenetic methods. Most coenopopulations have normal ontogenetic right-sided spectra with a maximum on the group of virginile or generative individuals. The state of coenopopulations is pessimal. The level of the ecological and geographical variability is significantly lower than the level of the intrapopulation variability. The data on the variability of morpho-parameters support the species independence of G. oschtenica.
Applicability of the vital dyes neutral red and fluorescein diacetate to differentiate between alive and dead non-copepod zooplankton
Authors: Litvinyuk Daria , Mukhanov Vladimir S.
Published: April 2020

It is a common practice for planktonologists to use neutral red (NR) staining to identify viable copepods in marine zooplankton. A new fluorescent dye, fluorescein diacetate (FDA), has also been successfully applied to Copepoda. Meanwhile, almost nothing is known about if NR- and FDA-based viability assays are applicable to many other zooplankton taxa. In this study, efficiencies of NR and FDA staining were evaluated and compared for different taxa and developmental stages of the Black Sea non-copepod zooplankton. Both the dyes were shown to stain well larvae of polychaetes, gastropods and bivalves, rotifers, fish eggs, barnacle nauplii, decapod zoeae, and the heterotrophic dinoflagellate Noctiluca sсintillans. Dominant species of Cladocera (Pleopis polyphemoides, Evadne spinifera, Pseudevadne tergestina) were stained efficiently with FDA only. Some taxa had sufficient statistics of positive staining only with one of the dyes, NR (e.g. appendicularians and chaetognaths) or FDA (e.g. barnacle cyprids). Correspondingly, more data are demanded to fill the gaps in the target taxa. The dyes proved to be taxa-specific and hence, their reliable application should be based on their target groups.
Analysis of Low Complexity Adaptive Step-size Orthogonal Gradient-based FEQ for OFDM Systems
Authors: Sitjongsataporn Suchada
Published: April 2020

We propose two low complexity adaptive step-size mechanisms based on the normalised orthogonal gradient algorithm for frequency-domain equalisation in orthogonal frequency division multiplexing (OFDM) systems. These algorithms are derived from employing a mixed-subcarrier exponentially weighted least squares criterion. Two low complexity adaptive stepsizeapproaches are investigated by exploiting an estimate of autocorrelation between previous and present weight-estimated mixed-subcarrier errors. We compare our approaches with a previously fixed stepsize normalised orthogonal gradient adaptive algorithm and other existing algorithm for implementation. Simulation results demonstrate that the proposed algorithms can achieve good performance for involving an OFDM receiver.

Authors: Shimamoto Haruki , Taki Tsuyoshi , Hasegawa Junichi
Published: April 2020

This paper presents an automated scoring system for the twist skill in Horizontal bar based on motion image analysis. In this system, training scenes of Horizontal bar are taken by a high-speed video camera, and then a gymnast’s region is extracted from a video image frame by frame based on a background subtraction method. Next, the body axis of the gymnast in the moment when a twist skill completed is estimated from the gymnast’s region. Finally, the deduction point for the twist skill is automatically decided according to the rules described in the Code of Points. In experiments using video images for 26 practices, it was shown that about 80.8% of the correspondence rate between estimated deduction scores and true ones calculated by the correct ‘SCF’ and ‘Body axis’ was obtained. This can be promising as a result at the preliminary stage of this research.

Published: April 2020

Design and evaluation of a CORDIC (COordinate Rotation DIgital Computer) algorithm for a floatingpoint division operation is presented in this paper. In general, division operation based on CORDIC algorithm has a limitation in term of the range of inputs that can be processed by the CORDIC machine to give proper convergence and precise division operation result. A hardware architecture of CORDIC algorithm capable of processing broader input ranges is implemented and presented in this paper by using a pre-processing and a post-processing stage. The performance as well as the calculation error statistics over exhaustive sets of input tests are evaluated. The results show that the CORDIC algorithm can be well-convergence and gives precise division operation results with broader input ranges. The proposed hardware architecture is modeled in VHDL and synthesized on a CMOS standard-cell technology and a FPGA device, resulting 1 GFlops on the CMOS and 210.812 MFlops on the FPGA device.

Authors: Hongesombut Komsan , Tephiruk Naowarat
Published: April 2020

High damping ratio and fast settling time are very challenges for improving the stability performance in power system. In this paper, an energy capacitor system (ECS) is applied in a two-area multi-machine power system to provide the transient stability enhancement. The algorithm for designing the robust damping controller of the ECS is based on the loop shaping control. The results from the design are the control parameters of the ECS damping controller with the constraint that the size of the ECS must satisfy the criteria of damping consideration. From the simulation results, it can be found that the ECS can effectively enhance the damping of power system oscillations. Moreover, the combination of ECS and the existing power system stabilizers (PSSs) allows exceptional performance and more desirable size of ECS.
Time Domain Equalization Method for DFTS-OFDM Signal without GI under Highly Mobile Environments
Authors: Reangsuntea Pongsathorn , Boonsrimuang Pisit , Mori Kazuo , Kobayashi Hideo
Published: April 2020

In highly time-varying fading channel, the Discrete Fourier Transform Spreading Orthogonal Frequency Division Multiplexing (DFTS-OFDM) signal would be damaged significantly by the inter-channel interference (ICI) due to the loss of orthogonality among subcarriers which leads a fatal degradation of bit error rate (BER) performance. To solve this problem, this paper proposes a time domain equalization (TDE) technique in conjunction with a time domain channel impulse response (CIR) estimation method for the DFTS-OFDM signal without using a guard interval (GI). The features of proposed method is to employ a time domain training sequence (TS) both for the estimation of time domain CIR at every sampling time and for removing the inter-symbol interference (ISI) incurred in the multipath fading channel. The proposed method also employs the TDE with a maximum likelihood (ML) estimation method in the demodulation of received time domain signal at every symbol instead of using the conventional Minimum Mean Square Error-Frequency Domain Equalization (MMSE-FDE) method. This paper presents various simulation results to demonstrate the effectiveness of proposed demodulation method for the DFTSOFDM signal without GI as comparing with the conventional MMSE-FDE and TDE methods both of usingGI under highly mobile environments.

Published: April 2020

In highly mobile environments, signal quality of discrete Fourier transform spreading-orthogonal frequency division multiplexing (DFTS-OFDM) with a frequency domain equalization method would be degraded due to the occurrence of inter-channel interference (ICI). To solve this problem, this paper proposes an iterative based time domain equalization (TDE) method with a time domain channel impulse response (CIR) estimation for DFTS-OFDM signals. The salient features of the proposed method are the use of a time domain training sequence (TS) in the estimation of CIR instead the conventional pilot subcarriers and to employ the TDE method with a maximum likelihood (ML) estimation instead of the conventional one-tap minimum mean square error frequency domain equalization (One-Tap MMSE- FDE) method. This paper also proposes a low complexity iterative based TDE method using the properties of a symmetric banded CIR transfer matrix for solving the simultaneous equations instead of direct calculation of an inverse matrix. It also presents various simulation results in highly mobile environments to demonstrate the effectiveness of the proposed iterative based TDE with CIR estimation for the TS inserted DFTS-OFDM signals compared to the conventional One-Tap MMSE-FDE method.
A Novel Direct Manipulation Technique for Motion-editing using a Timeline-based Interface
Authors: Pantuwong Natapon
Published: April 2020

Recently, motion data is becoming increasingly available for creating computer animation. Motion capture is one of the systems that can generate such motion data. However, it is not suitable to capture a lot of motion due to the cost of motion capture technique, and the diculty of its postprocessing. This paper presents a timeline-based motion-editing system that enables users to perform motion-editing tasks easily and quickly. A motion sequence is summarized and displayed in the 3D environment as a set of editable icons. Users can edit the motion data by performing a sequence of operations on a single key frame or over an interval. The recorded sequence is then propagated automatically to a set of target key frames or intervals, which can be either user dened or system dened. In addition, we provide a simple interaction method for manipulating the duration of specic intervals in the motion data. Methods for combining and synchronizing two dierent motions are also provided in this system. In contrast with the previous work that allows only temporal editing, the proposed system provides editing functions for both geometry and temporal editing. We describe a user study that demonstrated the eciency of the proposed system.

Published: April 2020

Cardiovascular diseases are chronic diseases that cause serious morbidity and mortality worldwide. Unfortunately, the patients with type 2 diabetes mellitus and hypertension have a high risk of having a cardiovascular complication. For these reasons, patients with type 2 diabetes mellitus and hypertension should be aware of cardiovascular complication along their healthcare journey. To prevent cardiovascular complication from diabetes and hypertension, accurate risk prediction is required for a long term self-management process. Consequently, this paper proposes a fuzzy logic based method for predicting cardiovascular risk particularly for a patient with type 2 diabetes mellitus and hypertension. This paper also proposes a set of factors based on the patient’s lifestyle as the key factors besides clinical factors because of their implicit impact on the quality of life of the patient. The proposed model thus employs 15 predictors for both clinical and lifestyle risk factors. Additionally, the proposed model is constructed based on the scientific data and implicit knowledge of the experts. The experiment with 121 patients shows that the proposed prediction model provides 96.69% accuracy compared to those decided by the experts.
The Vocational Knowledge Improvement Method for the Post-Modern Worker: A Case Study of the Tourism MRA Body of Knowledge Standards
Authors: Tongpaeng Yootthapong , Sureephong Pradorn , Chernbumroong Suepphong
Published: April 2020

The ASEAN member countries are going to implement the Mutual Recognition Arrangement (MRA) of Qualifications of Tourism Professionals which is the framework of competency standards with the aim to promote the equality of human resources in the tourism industry and to facilitate the mobility of tourism professionals. However, vocational education and training don’t seem to provide knowledge improvement for the worker in the postmodern era since the completion rate of MOOCs is very low. Therefore, the aim of this paper is to propose a knowledge improvement method for knowledge workers who are working in the tourism industry. In this study, the cognitive load theory and interactive media were employed as methods which are able to improve the knowledge workers’ learning performance via mobile devices. Two experiments were performed in order to find the optimal length of video lectures and the effectiveness of interactive media in MOOCs. The first experiment was performed on sixty-two tourism industry knowledge workers who were divided into four groups randomly. Each group was loaded with different video lengths and different segmentations. The second experiment was done on the same focus group by separating them into control and experiment groups. The experiment group was assigned to use interactive media (2D learning game) right after the learning video. The results show that, by providing the same amount of learning time, the group who were using the smaller video lengths performed significantly better than the other due to lower load of information. Differences in knowledge tests were examined across different conditions of video lengths to measure the learning performance. As a result, the groups which were equipped with interactive media achieved higher test scores than those in non-interactive groups. The evaluation method for the performance test was the same as the first experiment. The results indicate that the interactive group with smaller size of video length performed significantly better than the other group exposed to traditional online learning (using long video in a non-interactive manner).

Sleepwalking is a type of sleep disorder which originates during deep sleep and results in walking state and performing series of complex behaviors or actions while sleeping. In some cases, sleepwalking patients can injure themselves from their actions such as driving a car or climbing out of a window. In addition, to wake up the sleepwalkers can be difficult. The suddenly waking up and can cause them to be confused or even attack the person who wakes them. Therefore, detecting the sleepwalking incident in an early state can help the caretaker or family members to stop the patients before they harm themselves from any strange, inappropriate, or violent behaviors. In this research, we present a prototype system of sleepwalking detection algorithm and notification system using smart device which work coordinating with wearable device. There are two main groups of users; patients and caretakers. User Activity Sensor (UAS) in the wearable device is utilized for detecting User Activity Data (UAD) which is unusual activities of inducing a sleepwalking patient provided by the Remote Sensor SDK. The system returns the patient UAD states consisting of standing, walking, and running. The smart device accepts the UAD states from the wearable device, performs sleepwalking detection algorithms then, alarms caretakers when the sleepwalking state has already invoked. The system is implemented, built, tested and deployed. The threefold experimental measurement of physical user activites have been performed to validate our proposed sleepwalking detection algorithms. The system correctly detects the sleepwalking states and notifies the caretaker.
Enhanced Particle Swarm Optimization for Path Planning of Unmanned Aerial Vehicles
Authors: Kok Kai Yit , Rajendran Parvathy
Published: April 2020

This paper presents an enhanced particle swarm optimization (PSO) for the path planning of unmanned aerial vehicles (UAVs). An evolutionary algorithm such as PSO is costly because every application requires different parameter settings to maximize the performance of the analyzed parameters. People generally use the trial-and-error method or refer to the recommended setting from general problems. The former is time consuming, while the latter is usually not the optimum setting for various specific applications. Hence, this study focuses on analyzing the impact of input parameters on the PSO performance in UAV path planning using various complex terrain maps with adequate repetitions to solve the tuning issue. Results show that inertial weight parameter is insignificant, and a 1.4 acceleration coefficient is optimum for UAV path planning. In addition, the population size between 40 and 60 seems to be the optimum setting based on the case studies.

Published: April 2020

Small and medium-sized enterprises provide economic growth in many countries of the world. Economic pressure requires continuous improvement of the company's efficiency, staff knowledge, training to survive or remain competitive. Due to limited resources, often financial, SME managers reduce training activities and the introduction of new technologies in their companies.

The purpose of this article was to study the possibilities of e-learning in SMEs. The main trends of modern e-learning were considered.

It was noted that, despite the obvious advantages of using e-learning in SMEs, there were a number of obstacles to the active introduction of e-learning, namely: lack of availability of e-learning, lack of management support, lack of quality courses, reluctance of staff to use technology, lack of investment by companies in technology and lack of University-level and non-academic courses tailored to the needs of the enterprise.

The article considers possible ways of overcoming the described problems and suggests ways to solve them.
