An Enhanced Source Location Privacy based on Data Dissemination in Wireless Sensor Networks (DeLP)
Authors: Jan Naveed , Al-Bayatti Ali , Alalwan Naseer , Alzahrani Ahmed
Published: May 2019

Wireless Sensor Network is a network of large number of nodes with limited power and computational capabilities. It has the potential of event monitoring in unattended locations where there is a chance of unauthorized access. The work that is presented here identifies and addresses the problem of eavesdropping in the exposed environment of the sensor network, which makes it easy for the adversary to trace the packets to find the originator source node, hence compromising the contextual privacy. Our scheme provides an enhanced three-level security system for source location privacy. The base station is at the center of square grid of four quadrants and it is surrounded by a ring of flooding nodes, which act as a first step in confusing the adversary. The fake node is deployed in the opposite quadrant of actual source and start reporting base station. The selection of phantom node using our algorithm in another quadrant provides the third level of confusion. The results show that Dissemination in Wireless Sensor Networks (DeLP) has reduced the energy utilization by 50% percent, increased the safety period by 26%, while providing a six times more packet delivery ratio along with a further 15% decrease in the packet delivery delay as compared to the tree-based scheme. It also provides 334% more safety period than the phantom routing, while it lags behind in other parameters due to the simplicity of phantom scheme. This work illustrates the privacy protection of the source node and the designed procedure may be useful in designing more robust algorithms for location privacy.
Connected Vehicle as a Mobile Sensor for Real Time Queue Length at Signalized Intersections
Authors: Gao Kai , Han Farong , Dong Pingping , Xiong Naixue , Du Ronghua
Published: May 2019

With the development of intelligent transportation system (ITS) and vehicle to X (V2X), the connected vehicle is capable of sensing a great deal of useful traffic information, such as queue length at intersections. Aiming to solve the problem of existing models’ complexity and information redundancy, this paper proposes a queue length sensing model based on V2X technology, which consists of two sub-models based on shockwave sensing and back propagation (BP) neural network sensing. First, the model obtains state information of the connected vehicles and analyzes the formation process of the queue, and then it calculates the velocity of the shockwave to predict the queue length of the subsequent unconnected vehicles. Then, the neural network is trained with historical connected vehicle data, and a sub-model based on the BP neural network is established to predict the real-time queue length. Finally, the final queue length at the intersection is determined by combining the sub-models by variable weight. Simulation results show that the sensing accuracy of the combined model is proportional to the penetration rate of connected vehicles, and sensing of queue length can be achieved even in low penetration rate environments. In mixed traffic environments of connected vehicles and unconnected vehicles, the queuing length sensing model proposed in this paper has higher performance than the probability distribution (PD) model when the penetration rate is low, and it has an almost equivalent performance with higher penetration rate while the penetration rate is not needed. The proposed sensing model is more applicable for mixed traffic scenarios with much looser conditions.
Focusing Sensor Design for Open Electrical Impedance Tomography Based on Shape Conformal Transformation
Authors: Wang Yu , Ren Shangjie , Dong Feng
Published: May 2019

Electrical Impedance Tomography (EIT) is a non-invasive detection method to image the conductivity changes inside an observation region by using the electrical measurements at the boundary of this region. In some applications of EIT, the observation domain is infinite and is only accessible from one side, which leads to the so-called open EIT (OEIT) problem. Compared with conventional EIT problems, the observation region in OEIT can only be measured from limited projection directions, which makes high resolution imaging much more challenging. To improve the imaging quality of OEIT, a focusing sensor design strategy is proposed based on shape conformal theory. The conformal bijection is used to map a standard EIT sensor defined at a unit circle to a focusing OEIT sensor defined at an upper half plane. A series of numerical and experimental testes are conducted. Compared with the traditional sensor structure, the proposed focusing sensor has higher spatial resolution at the near-electrode region and is good at distinguishing multi-inclusions which are close to each other.
Multifunctional UV and Gas Sensors Based on Vertically Nanostructured Zinc Oxide: Volume Versus Surface Effect
Authors: Ocola Leonidas E. , Wang Yale , Divan Ralu , Chen Junhong
Published: May 2019

This article reports that it is possible to make multifunctional sensing devices with ZnO infiltrated polymers while the sensing interactions could occur throughout the polymer. As such, we find that infiltrated devices with SU-8 polymer can result in highly sensitive UV sensors. Mesh dielectric core devices were found to make sensitive gas sensors with a better than 5 ppm sensitivity for formaldehyde and NO2. A new type of p-n junction device is further demonstrated that is sensitive to UV illumination, thus making it an enhanced UV sensor. Sensing devices relying on volume interactions, such as light absorption, can significantly benefit from the infiltrated polymer. In contrast, devices that rely on surface interactions, such as gas sensors, do not gain performance in any significant way with or without the infiltrated polymer.
Hydrologic Evaluation of Integrated Multi-Satellite Retrievals for GPM over Nanliu River Basin in Tropical Humid Southern China
Authors: Liang Zhenqing , Chen Sheng , Hu Junjun , Huang Chaoying , Zhang Asi , Xiao Liusi , Zhang Zengxin , Tong Xinhua
Published: May 2019

Version 5B Integrated Multi-satellite Retrievals for GPM (IMERG) products were evaluated with rain gauge observations as reference over the Nanliu River basin in Southern China since March 2014 to December 2016 through the Xinanjiang hydrologic model. The IMERG products include the early run satellite-only IMERG product (IMERGERUncal), final run satellite-only and gauge-corrected IMERG products (IMERGFRUncal and IMERGFRCal, respectively). Direct comparison with the gauge observations indicates that both early run and final run IMERG products have good performances in capturing the precipitation at spatial and temporal characteristics. IMERGFRUncal and IMERGERUncal show compatible capabilities to detect rainfall in a daily scale with highly correlative coefficient (CC) about 0.67, relative bias (RB) about −20.79%, and root mean square error (RMSE) about 10.68 mm. IMERGFRCal performed a little better than IMERGFRUncal and IMERGERUncal with higher CC (0.7) and lower magnitude of RB (4.90%). Simulated stream flows with daily IMERG products as forcing data show a large deviation from the observed stream flows with low Nash-Sutcliffe index (NSCE) < 0.3, indicating that all of these IMERG products have limited potentials of hydrological utilization in this basin. Particularly, IMERGFRCal shows relatively poor NSCE (0.28) and underestimates the stream flow by 7.83%. IMERGFRUncal and IMERGERUncal exhibit better performance than IMERGFRCal in the hydrological simulation with higher NSCE (0.30 and 0.29, respectively) and larger deviations with RBs about −56.73% and −59.49%, respectively. This result manifests that the IMERG products users need to be cautious when using IMERG products for hydrological applications in this basin. Additionally, this study is expected to offer insights into IMERG’ potentials in the hydrological utility and thus provide useful feedbacks to the IMERG algorithm developers and the users.
Pape s početka trećeg tisućljeća i njihov odnos prema smrtnoj kazni
Authors: Petrov Emanuel
Published: May 2019

U radu je prikazan napredak crkvenog učenja o pitanju smrtne kazne u vrijeme trojice posljednjih papa. Premda je tek uredbom pape Franje smrtna kazna proglašena definitivno nedopustivom zbog nepovredivosti dostojanstva čovjeka i prava na život, učenje i istupi njegovih prethodnika Ivana Pavla II. i Benedikta XVI. potvrđuju jednak stav. Svakako, primjetan je razvoj shvaćanja u izmjenama članaka 2266 i 2267 Katekizma Katoličke Crkve, kako bi se bolje sačuvao i izložio dragocjeni polog kršćanskog nauka, a za koji je potrebno sazrijevanje vremena. U skladu s apostolskom konstitucijom Fidei depositum, kojom je sam Katekizam odobren 1992. godine trojica su papa u ovom pitanju vjerno stajali na braniku čovjekova dostojanstva, izlažući nauk na temelju Objave, Svetoga pisma i Crkvene predaje, nastojeći osvjetlati svjetlom vjere nove prilike i poimanja suvremenog društva.

Cappellin simplified sinus lift protocol for mini-invasive lateral approach - Preliminary study results
Authors: Cappellin Mario
Published: May 2019

Purpose: The lateral approach in sinus lift allows to optimally manage severe bone resorption in posterior maxilla in order to place implant supported prosthesis; however, the conventional protocols requires bigger window and cannot determine in advance the precise position for bone incision, so in many cases the detachment of Schneider membrane is more difficult if the bone isn’t cut near the sinus floor or if there is a bone septum. The aim of Cappellin simplified sinus lift protocol is to minimize the surgical difficulties with a surgical guide realized from STL 3D printed model (conversion of DICOM cone-beam CT files).
Case report: In our study (since 2013 to 2017) in 125 sinus lift cases (performed with Geistlich Bio-Oss® and a-PRF / PRGF) with 210 implants (Implant Direct® Legacy 2, 78 of which were placed at the same time as the sinus lift augmentation) we obtain a success of 100% for the sinus lift augmentation and 100% survival rate for the implants; we also drastically reduce the surgery time (average is about 25 minutes). CT scans were performed before the surgery and 4-6 months after the sinus lift; follow up for implant survival includes control and professional hygiene every 6 months.
Conclusions: In regards of these preliminary results, Cappellin simplified sinus lift protocol offers advantages in terms of safety, simplicity, quickness, reliability and allows to reduce the economic costs of the procedure.
Rehabilitation of atrophic maxilla with tilted implants - Case report
Authors: Tavares Catarina , Pires Cidália
Published: May 2019

Abstract
Purpose: An 81-year-old male patient, without systemic disorders, came to the appointment referring lack of masticatory function. It was planned a rehabilitation with six implants in upper atrophic maxilla (Implant Direct – Swish Plus), including immediate placing of 4 implants and 2 posterior tilted implants due to the severe pneumatization of maxillary sinus and bone ridge resorption. The prosthetic phase was initiated 4 months after implants surgery.
Case report: The placement of tilted implants with the objective of the necessity of bone grafts and increase bone support has been reported by several authors as a viable rehabilitation. And since it is a minimally invasive surgery, it has good acceptance by the patient. The placement of tilted implants is a viable surgical alternative in anatomic regions such as: the anterior or posterior wall of the maxillary sinus, the palatal curvature or the pterygoid process. This treatment option, allied to the use of longer implants, allows an improved primary stability favoring immediate loading. Also, allows the adequate distribution of the implants, resulting in a more uniform distribution of forces and avoids the necessity of cantilever. Some authors have been questioning the biomechanical qualities of this surgical option; however, there are no statistical differences when compared with implants conventionally placed.
​Conclusions: Tilted implants allow an implant-supported rehabilitation of atrophic maxilla without bone grafts, which decreases the waiting period, the patient’s morbidity and the costs of the treatment.

Alien plants in Central European river ports
Authors: Jehlík Vladimír , Dostálek Jiří , Frantík Tomáš
Published: May 2019

River ports represent a special type of urbanized area. They are considered to be an important driver of biological invasion and biotic homogenization on a global scale, but it remains unclear how and to what degree they serve as a pool of alien species. Data for 54 river ports (16 German, 20 Czech, 7 Hungarian, 3 Slovak, and 8 Austrian ports) on two important Central European waterways (the Elbe-Vltava and Danube waterways) were collected over 40 years. In total, 1056 plant species were found. Of these, 433 were alien, representing 41% of the total number of species found in all the studied Elbe, Vltava, and Danube ports. During comparison of floristic data from literary sources significant differences in the percentage of alien species in ports (50%) and cities (38%) were found. The number of alien species was closely related to port size, but the proportion of alien species expressed as a percentage of the total number of species did not depend significantly on port area. The proportion of alien species in both studied waterways decreased with distance from the sea and was highest in the Hungarian ports and lowest in the Czech Republic, Austria and Bavaria. Lower levels of shipping towards inland regions due to decreased river flow are likely the reason for this trend. The dissimilarity in the species composition of alien and native flora between individual river ports increased with increasing inter-port distance. Neophytes presented a stronger distance decay pattern than did either native species or archaeophytes of the Danube inland ports, potentially due to the different cargoes of individual ports, which may affect the introduction of different neophytes from different geographic areas. The results show that river ports in Central Europe should be regarded as a type of industrial area and deserve full attention with regard to the distribution and spread of alien plants.

Jama Kaltbach je razvita v Hochgantskem eocenskem peščenjaku na območju Siebenghengste v Švici. Rezultat ponovne izmere jame je precej večja dolžina, nov načrt jame in številna opažanja, ki kažejo na to, da jama ni nastala z »normalno speleogenezo«, ampak je t.i. fantomska jama. Fantomske jame nastajajo pri delnem preperevanju nečistega apnenca v toplih klimah, v pogojih nizkega hidravličnega gradienta. Ob povečanju gradienta, voda izpere netopni preostanek, pri čemer nastane jama. Članek obravnava geomorfološke značilnosti jam, ki nam omogočajo prepoznavati fantomske jame.  Kaltbach cave is developed within the Eocene Hohgant sandstone in the Siebenhengste area in Switzerland. A remapping project of the cave resulted in a huge increase in length. It also produced a complete, updated map and longitudinal section. The cave’s morphology does not fitwiththe“normal”speleogenesis:itisaso-calledphantom cave. Phantoms are created by differential weathering of impure limestone under a preferably warm climate and a very low hydrologic gradient. Once the gradient steepens, the undissolved residual sediments are piped out; the “cave” manifests itself. The paper discusses the geomorphological features that permit to recognize the phantom caves.
Hydrogeological research as a basis for the preparation of the plan of monitoring groundwater contamination: A Case Study of the Stara Vas Landfill near Postojna (SW Slovenia)
Authors: Petrič Metka , Šebela Stanka

V Sloveniji je na krasu trenutno aktivnih devet odlagališč komunalnih odpadkov, med drugimi tudi Stara vas pri Postojni. Ker je za kraška območja značilna močna razpokanost kamninske osnove in zelo dobra prepustnosti, izcedne vode z odlagališč še posebej ogrožajo podzemno vodo. Sposobnost naravne filtracije je v krasu majhna,obseg možnega negativnega vpliva pa zelo velik. Sedaj veljavna zakonodaja predpisuje obratovalni monitoring, del katerega je tudi merjenje parametrov onesnaženosti podzemnih vod z nevarnimi snovmi, če so v vplivnem območju odlagališča. Temelj za izdelavo načrta monitoringa so ustrezne hidrogeološke raziskave. Za primer Stare vasi smo poleg osnovnih geoloških in hidrogeoloških podatkov uporabili še rezultate sledilnih poskusov, ožje območje odlagališča pa smo podrobno tektonsko-litološko kartirali v merilu 1:5000. Na osnovi ugotovljenih značilnosti pretakanja vode v podzemlju in v skladu s predpisi smo določili 3 točke monitoringa znotraj (izvira Malenščica in Vipava, jama Fužina) in eno izven vplivnega območja odlagališča (Matijeva jama) ter določili način spremljanja kakovosti vode in izdatnosti   For the present 9 land fills on karst are still active in Slovenia, among them also the Stara vas land fill near Postojna. As strong fissuration of the rock base and very good permeability istypical for karst areas, the waste waters from the landfills particularly endanger the groundwater.The capacity of natural filtration in karst is very low and the dimension of possible negative impact is very high. The actual legislation regulates the performance of operational monitoring, a part of which is also the measurement of parameters of contamination of groundwater by hazardous substances, if they are in the area of influence of the landfill. Preparation of the monitoring plan is based on adequate hydrogeological researches. Besides basic geological and hydrogeological data also the results of tracer tests were used in the case study of the Stara vas landfill.Additionally, the detailed tectonic-lithological mapping in the scale 1:5000 was performed in the narrow area of the landfill.Based on defined characteristics of underground water flow and in accordance with the regulations 3 monitoring points inside (Malenščica and Vipava springs, Fužina cave) and one point outside the area of influence of the landfill (Matijeva jama cave) were selected. The monitoring plan for the observation of water quality and capacity was suggested.

Authors: Gabrovšek Franci
Published: May 2019

Speleologically, a »pie« of mainly carbonate conglomerate atop of a sequence of impermeable oligocene and mainly fed by autochtonic waters, represents a simple speleological settings. There are 14 registered caves in the area, mostly concentrated along the western rim of the terace. Four caves extend more than 200 m, the cave Arneževa luknja is the longest with 815 m. In the chapter I describe the general speleological settings in Udin boršt, characteristics of caves and factors important for their genesis. Udin boršt je relativno enostaven primer speleološkega okolja. Stik med pleistocenskim konglomeratom in oligocensko morsko glino prestavlja ploskev, ob kateri se razvijajo jame. Na območju Udin boršta je registriranih 14 jam. Večina vhodov se nahaja na zahodnem robu konglomeratne terase. Štiri jame so daljše od 200 m, Velika Lebinca je po zadnjih raziskavah s 1150 metri najdaljša. V prispevku obravnavam specifičnosti speleološkega okolja, v katerem so nastale te jame, faktorje, ki so pomembni za njihov razvoj in opišem osnovne značilnosti jam Udin boršta.

Synanthropic flies are members of order Diptera and considered as medical and veterinary pests. In this study, parasitoid wasps were determined and their natural host preferences in order to select a suitable agent for biological control of flies. The pupae of three species of flies; Musca domestica, Lucilia sericata and Sarcophaga haemorrhoidalis were used as hosts for natural parasitoids. For this issue, as much as 50 pupae of each fly species put in three separate dishes with covered top by a net. These dishes were placed in the field to attract parasitoid wasps. The most parasitic rate was related to N. vitripennis (%17.2). Host preferences of N. vitripennis on M. domestica pupae were higher than observed parasitism on L. sericata and S. haemorrhoidalis. The emerging rate of two parasitoids; P. vindemmiae and S. nigroaenea were one per host pupae. According to the result, N. vitripennis can be an appropriate candidate for use as natural enemy which expected to be effective in controlling various species of synanthropic flies. Therefore, S. nigroaenea was more suitable to biological control of housefly populations.
Vision problems: A review of prevalence studies on refractive errors in school-age children
Authors: Atowa Uchenna C. , Hansraj Rekha , Wajuihian Samuel O.
Published: May 2019

Background: Refractive errors are common eye disorders and are leading causes of visual impairment in the general population. Children with uncorrected refractive error may experience reduced visual acuity, transient blurring, headache and persistent ocular discomforts particularly for close work which can impair reading efficiency and school performance.Aim: This article documents the prevalence of refractive errors in school-age children of different ethnic origins. The goal is to identify possible variation in measuring techniques and diagnostic criteria, as well as limitations of studies, to provide a clear direction for future studies.Methods: The review was undertaken through a detailed evaluation of peer-reviewed publications of primary research on this topic. The keywords for the search included ‘refractive error’, ‘hyperopia’, ‘myopia’, ‘astigmatism’ and ‘school children’. Only epidemiological studies with participants between 5 and 18 years of age were included.Results: Although several population and school-based studies have been conducted in various racial groups and populations, their findings were diverse owing to inconsistencies in the methods applied in identifying children in need of refraction, measurement techniques and diagnostic criteria for refractive errors. There are also some limitations associated with the sampling design and characteristics, which may have influenced the outcome measures.Conclusion: Despite the problems inherent in the studies, the review indicates that refractive error in school-age children is a public health concern in those populations and warrants additional research that will provide reliable data for proper planning of intervention strategies.
Spinal cord injured patients’ knowledge of pressure sores

Published: May 2019

Despite much effort being put into educating spinal cord injured patients on pressure sore prevention, pressure sores remain a major cause of morbidity and mortality. This study sought to establish: i) paraplegics’ knowledge on pressure sore prevention prior to discharge; ii) the influence of knowledge on pressure sore occurrence during hospitalization; iii) sources of paraplegics’ knowledge on pressure sore prevention. A total of twenty-six men and two women with paraplegia aged between 18 and 45 years participated in the study. A rospective pre-test post-test method using a structured questionnaire was used to test paraplegics’ knowledge on pressure sore prevention. The first interview was done within one week of mobilising in a wheelchair and the second one after two months or a few days before discharge. Pressure sore occurrence and the source of knowledge were also recorded. The results showed that paraplegics’ knowledge on pressure sore prevention at discharge is incomplete. Knowledge gain does not seem to determine whether one will develop pressure sores or not. Physiotherapists (89%), nurses (82%) and occupational therapists (68%) are the main educators of paraplegics on pressure sore prevention in rehabilitation hospitals.
Problem based curricula and problem based learning in physiotherapy: A critical review
Authors: Eksteen C. A. , Slabbert J. A.
Published: May 2019

Introduction: Problem based curricula and problem based learning are used extensively to facilitate learners to become effective learners and through that, effective professional problem solvers. The basic characteristics of the problem based curriculum and the processes of the problem based learning are described in the literature but many variations of problem based learning and the problem based curriculum exist. Research findings are also contradictory regarding the effectiveness of these approaches. The aim of this article is to discuss the theoretical foundation of these approaches and to identify the core issues that must be addressed in order to optimize their effect on learners.Methodology: A literature search was done by using the following keywords: problem based curriculum, problem based learning, clinical decision making, clinical problem solving, clinical judgement, physiotherapy, medicine, health care, and health care education.Discussion: There is a lack of research in the literature that shows evidence that the problem based curricula and problem based learning is more beneficial for students’ learning or mastering specific competencies than learning in a traditional curriculum. Papers on problem based curriculum and problem based learning describe the process and state the desired effects of the teaching approaches without explicitly describing the contextual and transactional environments, as well as the internal (departmental) environment in which the change in teaching approach took place and how it was adapted to their situation. Furthermore, no research could be found on ways to address the negative outcomes of problem based learning. There is thus a need for well designed research protocols to show the best evidence of physiotherapy educational practice.

Test positivity rate (TPR)—confirmed cases per 100 suspected cases tested, and test-confirmed malaria case rate (IR)—cases per 1,000 population, are common indicators used routinely for malaria surveillance. However, few studies have explored relationships between these indicators over time and space. We studied the relationship between these indicators in children aged < 11 years presenting with suspected malaria to the outpatient departments of level IV health centers in Nagongera, Kihihi, and Walukuba in Uganda from October 2011 to June 2016. We evaluated trends in indicators over time and space, and explored associations using multivariable regression models. Overall, 65,710 participants visited the three clinics. Pairwise comparisons of TPR and IR by month showed similar trends, particularly for TPRs < 50% and during low-transmission seasons, but by village, the relationship was complex. Village mean annual TPRs remained constant, whereas IRs drastically declined with increasing distance from the health center. Villages that were furthest away from the health centers (fourth quartile for distance) had significantly lower IRs than nearby villages (first quartile), with an incidence rate ratio of 0.40 in Nagongera (95% CI: 0.23–0.63; P = 0.001), 0.55 in Kihihi (0.40–0.75; P < 0.001), and 0.25 in Walukuba (0.12–0.51; P < 0.001). Regression analysis results emphasized a nonlinear (cubic) relationship between TPR and IR, after accounting for month, village, season, and demographic factors. Results show that the two indicators are highly relevant for monitoring malaria burden. However, interpretation differs with TPR primarily indicating demand for malaria treatment resources and IR indicating malaria risk among health facility catchment populations.
