Validation of Vehicle Speed Analysis Utilizing the iNPUT-ACE Camera Match Overlay Tool
Authors: Jorgensen Michael , Swinford Scott , Jones Brian
Published: May 2021

Traffic cameras, dash-cameras, surveillance cameras, and other video sources increasingly capture critical evidence used in the accident reconstruction process. The iNPUT-ACE Camera Match Overlay tool can utilize photogrammetry to project a two-dimensional video onto three-dimensional point cloud software to enable measurements to be directly taken from the video. Those measurements are commonly used, and critical for, the determination of vehicle speed in accident reconstruction. The accuracy of the Camera Match Overlay tool has not yet been thoroughly examined. To validate the use of the tool to measure vehicle speed for accident reconstruction, data were collected from a series of tests involving three traffic cameras, a stationary and moving dash-camera, a stationary and moving cell-phone camera, and a doorbell surveillance camera. Each camera provided unique specifications of quality and focal length to ensure the tool would be tested in a variety of scenarios. Vehicles drove past the various cameras at a variety of distances and angles with vehicle speeds that ranged from approximately 15.5 kph (9.6 mph) to 90.2 kph (56.1 mph) as recorded by a RACELOGIC VBOX GPS system. A bright flash was utilized to synchronize timing between VBOX and video data. The resulting comparison between VBOX data and the tool’s distance and timing data revealed the iNPUT-ACE Camera Match Overlay tool was an effective method for analyzing vehicle speed across a variety of video sources.
An Examination of Equations Relating Motorcycle Impact Speed to Struck Vehicle Post-Impact Rotational Displacement
Authors: Rose Nathan , Carter Neal
Published: May 2021

When a motorcycle collides with a passenger vehicle, the impact can cause a change in the translational and rotational velocities of the struck vehicle. If these velocity changes, or the magnitude of the translation and rotation of the struck vehicle can be quantified, then these can potentially be used to calculate the impact speed of the motorcycle. There are several methods that could be used for this analysis. The most general and comprehensive solution will be to use one of the widely-accepted accident reconstruction simulation programs - PC-Crash, HVE (the EDSMAC4 or SIMON modules), Virtual CRASH, or VCRware. However, these simulation programs can be time-consuming to apply and not everyone has access to them. It would be useful to have simple formulas for obtaining a reasonable estimate of the motorcycle impact speed based on the observed post-impact translation and rotation of the struck vehicle. All the more useful if a method could be based on the struck vehicle rotation alone. And, in fact, several such methods exist in the literature.

This paper tests these methods for obtaining an initial estimate of a motorcycle’s impact speed based on the struck vehicle’s post-impact rotation alone. The accuracy of the methods is assessed and the sensitivity of the methods to various parameters are discussed. This paper demonstrates that the initial translational velocity of the struck vehicle significantly affects the magnitude of the struck vehicle’s post-impact angular displacement. Thus, methods that consider both the translation and rotation of the struck vehicle are more accurate than methods that rely on the struck vehicle rotational displacement alone.

Published: May 2021

Aerodynamic technologies for light-duty vehicles were evaluated through full-scale testing in a large low-blockage closed-circuit wind tunnel equipped with a rolling road, wheel rollers, boundary-layer suction and a system to generate road-representative turbulent flow. This work was part of a multi-year, multi-vehicle study commissioned by Transport Canada and Environment and Climate Change Canada, and carried out in cooperation with the US EPA, to support the evaluation of light-duty-vehicle greenhouse-gas-emission regulations. A 2016 paper reported drag-reduction measurements for technologies such as active grille shutters, production and custom underbody treatments, air dams, ride height control and combinations of these. This paper describes an extension to that work and addresses vehicle aerodynamics in three ways. First, whole vehicle body-shaping changes were evaluated by adding older or newer generation models, representing distinct body style redesigns, of select vehicles of different classes from the 2016 study. Second, newer vehicles were added to represent the market application of advanced aerodynamics in terms of body shaping and drag-reduction technologies. Third, drag reduction over a range of yaw angles is reported for new technologies such as side-mirror removal (for replacement with camera systems) and air curtains. This paper focuses specifically on drag measurements, complementing a 2019 paper which focused on relating mean surface, wake and underbody pressure measurements to aerodynamic drag for a selection of the test vehicles.

The most effective redesign of a vehicle was found to reduce the wind-averaged drag area by 9% compared to the previous model. The best commercial or idealized applications of the top performing technologies, namely ride height control, underbody panels and active grille shutters, provided wind-averaged drag area reductions in the 6% to 8% range. Idealized technologies performed better than their commercial counterparts. The best applications of other technologies like side mirror removal and OEM air dams were in the range of 3% to 5% reduction in wind-averaged drag area. All OEM air curtains performed better when combined with ride height reduction but still only reduced wind-averaged drag area by around 1% in the best case. The complete range of results, yaw effects and comparison with previously published results are presented and discussed in this paper.
Aerodynamic Simulation of a Standalone Round and Deforming Treaded Tire

Published: May 2021

For a typical passenger ground vehicle, the rotating treaded tires and wheel housings typically account for up to 25% of the total vehicle aerodynamic drag. Due to the importance of tires and their treads to the overall vehicle aerodynamics, it’s critically important for aerodynamics departments to have accurate simulations that can predict the effects of rotating tires. Accurate prediction of flow around a tire is a complex phenomenon and is affected by details of tire features such as tread pattern, air pressure, and tire deformation. In particular, the physics of the tire treads spatial movement and deformation (i.e. expansion, contraction, sidewall bulge, and squeezing of airflow) as the tires rotate and come in contact with ground, especially around the contact patch, is vitally important in determining accurate wheel wakes, underbody flow, and the overall wake of the vehicle. Recent developments have expanded an existing capability for simulating solid body motion to simulating a true deforming tire with accurate representation of tread motion, deformation, contact patch and sidewall bulge. The current study incorporates a Lattice Boltzmann method (LBM) based CFD solution using an Immersed Boundary method (IBM) to simulate and validate a realistically rotating and deforming standalone treaded tire. For ease of use, the solution doesn’t require the user to prescribe the motion and deformation of the tire, but rather automatically calculates the changes in time from a single stationary representation of the deformed tire. Simulations using this new capability demonstrate significant improvements over previously published results, which used round rotating treaded tires. Results are validated against previous wind tunnel experimental measurements. Further discussion on the effect of tire loading (i.e. bulge deformation) on wake results is also presented and discussed.

Published: May 2021

Since the introduction of the DrivAer in 2012 this model has become the standard generic aerodynamic benchmark and aerodynamic research model used by automotive OEMs, software vendors and researchers. In 2017, the relevance of the DrivAer has been furthered by the inclusion of a simplified engine bay. Whilst the DrivAer has become the popular standard, the availability of detailed wind tunnel test data, a key enabler for more sophisticated aerodynamic benchmarking and research, remains limited. This paper presents a comprehensive set of wind tunnel test data of the notchback version of the Ford Open Cooling DrivAer, including aerodynamic force measurements, detailed surface pressure measurements and flow field measurements at 3 cross-sections in the vicinity of the model. In addition, the paper will discuss the sensitivity of the experimental data to wind tunnel repeatability and facility-to-facility variations. Finally, a comparison of test results obtained for the Ford and the Hyundai DrivAer model will demonstrate the sensitivity of the measured aerodynamic characteristics to physical model build.

Published: May 2021

INTRODUCTION
Complex drug management is a common challenge in the treatment of geriatric patients. Pandemic scenarios, such as the current one (COVID-19), call for a reduction of face-to-face meetings, especially for elderly patients. Therefore, the aim of the present study was to compare the innovative concept of applying telemedical assessment to geriatric patients in the emergency department (ED) with ED standard treatment. The therapeutic recommendations regarding drug management from the two assessments were compared. A special focus was the use of potentially inadequate drugs (PIMs) for geriatric patients according to the “Fit for the Aged” (FORTA) classification.

METHODS
50 patients (40% female) aged ≥70 years and assessed with an Identification of Seniors at Risk Score (ISAR score) of ≥2 admitted to the ED were prospectively enrolled in this study between November 2017 and February 2018. In addition to the standard treatment in the ED, co-evaluation via video transmission was independently carried out by a board-certified geriatrician. Drug recommendations by ED physicians (A) and the geriatrician (B) were compared.

RESULTS
There was a significantly higher frequency of recommendations regarding changes to preexisting medication (p <0.001, n = 50) via geriatric telemedicine in comparison with standard ED treatment. The geriatrician intervened significantly more often than the ED physicians: discontinuation of a drug, p <0.001; start of a new drug, p = 0.004; dose change of a drug, p = 0.001; n = 50). Based on the additional therapy recommendations of the geriatrician, the amount of medication taken by the patient was significantly reduced compared with standard ED treatment (ED assessment t(49) = 0.622 vs geriatrician’s assessment t(49) = 4.165; p <0.001; n = 50). Additionally, the number of PIMs was significantly reduced compared with standard medical treatment (p <0.001). The geriatrician changed 53.9% of the drugs (35/65) whereas the ED physicians changed only 12.3% (8/65). Recommendations for immediate drug therapy, however, were made more frequently by ED physicians (p <0.039, n = 50).

DISCUSSION
An early assessment of elderly emergency patients by a geriatrician had a significant impact on the number of drug interventions in the ED. The number of PIMs could be significantly reduced. Whether this also has a positive effect on the further inpatient course needs to be investigated in further prospective studies.
The study was retrospectively registered at ClinicalTrials.gov (NCT04148027).
Losing your virginity safely? A Swiss national survey
Authors: Meuwly Marion , Auderset Diane , Surís Joan-Carles , Barrense-Dias Yara
Published: May 2021

WHAT IS KNOWN ON THE SUBJECT: Good practice and knowledge in terms of contraception at first sexual intercourse may lead adolescents to a safer sexual life. To date, research studies have mostly focused on women when investigating contraception use or on condom use only when addressing both genders.
WHAT DOES THIS ARTICLE ADD: The present study adds to the current knowledge by offering a more in-depth view of contraception use at first intercourse among youths. This is achieved through a large selection of variables, the fact that we address both males and females and that we have considered a wide range of contraceptive means.

AIM OF THE STUDY
To determine the rate of contraception use at first intercourse by youth in Switzerland and its association with social and personal characteristics.

METHODS
Data were obtained from a self-administrated national survey on sexual behaviour among young adults (mean age 26 years). Participants (n = 4036) were divided into three groups based on the means of contraception used at first intercourse: condom, with or without contraceptive (86.4%), contraceptive only (8.3%) and non-use (5.3%).

RESULTS
Only 5.3% did not use any contraception. Compared with the condom group, individuals in the non-use group were more likely to report a lower family socioeconomic status, to be foreign born, to have foreign-born parents, to have a non-intact family and to live in a Catholic canton. They were also more likely to have had their first intercourse in the context of a casual relationship, to have been intoxicated at the time and more likely to regret it. Participants in the contraceptive group reported a higher family socioeconomic status, had intact families, did not live in Catholic cantons, were older and in a steady relationship at first intercourse.

CONCLUSION
Contraception is generally used at first intercourse in Switzerland. Improvements can still be made concerning contraception use in the most vulnerable social strata such as low income families or foreign status.

Semanggi (Marsilea crenata Presl.) is one of the aquatic plants that have been widely used by the community as food and medicinal raw materials. One of the important factors in cultivating clover is optimal fertilizer management. The incorporation of organic and inorganic nutrients has an effect on soil fertility has been repeatedly demonstrated in several studies, but there are not specific guidelines on clover cultivation. The challenge now is to combine organic matter of different qualities with inorganic fertilizers to optimize nutrient availability for the clover plant. The results of research on clover cultivation have also not been widely carried out. Therefore, it is very important to do this research with the aim of knowing the optimal effect of organic (cow manure) and inorganic (nitrogen, potassium) fertilizers on the growth and yield of clover (Marsilea crenata Presl.). The research was conducted at the Screen House of the Faculty of Agriculture, Brawijaya University. The study was designed using a non-factorial randomized block design (RBD) with 8 (eight) treatment combinations of soil types and fertilization [inorganic (N, K) cow manure organic fertilizer (CM)], namely: P0 = soil, without fertilizer; P1 = soil, 138 kg N ha-1; P2 = soil, 136 kg K ha-1; P3 = soil, N and K, 138 and 136 kg ha-1; P4 = soil, 20x103kg of cow manure ha-1; P5 = soil, 20x103 kg of cow manure ha-1, 138 kg N ha-1; P6 = soil, 20x103 kg of cow manure ha-1, 136 kg K ha-1; P7 = soil, 20x103 kg of cow manure ha-1, N and K, 138 and 136 kg ha-1 with 3 replications, so that 24 experimental units were obtained. Each experimental unit consisted of 5 plants. Growth observations were observed destructively at the ages of 4, 8, 12, 16, 20, 24, 28, 32 days after planting (DAP). The results showed that there was an increase in the growth and yield of biomass in the soil combination, 20x103 kg of cow manure ha-1 (P4) was compared with the treatment without the addition of organic fertilizers (cow manure) on plant growth and yield parameters, such as stolon length (74.78 cm), number of leaves (160.44), leaf area (1379.28 cm2), root length (23.85 cm), stomata density and number of stomata (13.25); Stomata width (10.87 cm); Stomata length (19.76 cm), leaf fresh weight (12,907 g), leaf dry weight (1,802 g), total fresh weight 210,830 g, total dry weight 7,823 g, leaf harvest fresh weight (64.19 g); stalk (130.54 g); root (79.75 g); total 274.48 g), harvest dry weight of leaves (11.36 g); stalk (24.88 g); root (9.55 g); a total of 45.78 g) and the chlorophyll a content (0.804 mg.g-1); chlorophyll b (1.121mg.g-1); and total chlorophyll (1.924 mg.g-1).

Published: May 2021

Forming national identity is placed on top of the seven aspects of High-Impact Educational Practices (HIEPs) in Northern Border University. Similarly, the concept of academic awareness to national literature has been one of the main challenges to national literature in the Middle East. Just as the strong presence of national identity in Saudi’s 2030 vision has initiated re-evaluations of how national identity is shaped, Saudi novel has similar concerns that inform social constructs of national identity through overarching themes and comprehensive representations of cultural issues. This study investigates the ways in which two Saudi novelists interrogate the intertwined issues shared by 2030 vision and national novel which address the archetypal Saudi identity: first, that the construction of modern identity requires much cultural openness with the world; second, that construction of Saudi identity needs exclusion of otherness; and third, that national identity depends on the rich history of two historical regions – Najd and Hijaz - that binds identity to a unified territory. The study focuses on how these novels give visibility to issues that are at the core of 2030 vision’s social and cultural aspect such as life style, appearance behaviours, attitudes, accepting differences and willingness to work and volunteer. Drawing on this narrative analysis, the study advocates for the utility of introducing national novel for undergraduate students to help them perceive identity as a position and support their identity enactment.

Mining of rock minerals in the sandstone and gravel type is a mining commodity owned by the people of Lombok East Regency which requires supervision by the local government. Unfortunately, there are still problems in monitoring mining activities of excavated rock materials, which are not in accordance with mining principles. This study aims to determine the role of the local government in the supervision of mining excavated rock materials as well as the factors that influence the existence of the activities in Lombok East Regency. This research uses an empirical legal method, which is a study examining problems according to facts that take place in the field. The results show that the Lombok East Regency Government no longer has the authority to supervise the mining since it has been taken over by the Provincial Government, starting with the issuance of Law No. 23 of 2014 concerning the Regional Government. The factor hampering the mining supervision and licensing process is that it is difficult for miners and mining companies to apply for permits whereas business owners are obliged to obtain mining permits from the Provincial Government. Given the great distance, this has been one of the factors causing many illegal mining activities to occur in Lombok East Regency.

This study examined the change in vegetation cover (land use cover) of Kebbe forest reserve, Kebbe local government area of Sokoto state. The research was divided into phases comprising satellite image sourcing; corrections of the images and classification of the land cover types based on the result from the ground truthing of the Kebbe Forest reserve. Two research hypotheses and research objectives were formulated for the study. Satellite images of 5 thematic mapper (TM) of 2003 and 8 operational land imager thermal infrared sensor (OLI-TIRS) of 2018 were selected for this study. The data were haze corrected using pancroma software with the Dark Object Subtraction (DOS) algorithm. The highest increase in area among the LUC between the dates is the shrub land with about 20.42% increase, which is from 138.42 to 881ha and the least being the sparse forest with 1.35% increase, also from 1309.59 to 1359ha of the reserve. On the other hand, the highest decrease was experienced in the deep forest, with 24.89% of the decrease being from 1649.25 to 744ha, and the least being the bare land with 8.73% decrease, which is from 406.71to 89ha of the total reserve area. The results from this study indicate that the reserve of the Kebbe forest is not properly managed, and has also faced high degradation rate that affected the land use and land cover of the reserve. Forest conservation measures should be put in place to salvage the remaining forest land area. Further research into the causes of the forest degradation should be conducted.
Secular Changes in Mean Height of Children in Japan and South Korea-Suspension in Height Increases and BMI
Authors: Mori Hiroshi
Published: May 2021

Japan and South Korea achieved marvelous economic progress after WWII. Food consumption increased in quantity and quality, with animal-sourced products conspicuously augmented. Children grew in height unprecedentedly. Japanese children, however, ceased to grow taller in the 1990s, while supply of animal protein was still increasing. Korean children kept growing taller to overtake their Japanese peers by 3 cm in the mid-2000s, but they also stopped to grow any taller afterwards, while animal products kept increasing vigorously toward the end of the 2010s. Children in Japan started to turn away from fruit in the mid-1970s, to eat in the 2000s less than 10% of fruit by the older generations. Children in Korea started to steer away from vegetables in the early 1990s, to eat less than 10% of vegetables eaten by the older generations in their 50s-60s in the mid-2010s. Consuming sufficient animal-sourced products with very little vegetables/fruit, children, particularly in South Korea have been increasing in BMS in the past two decades, with a sign of declining height.

The genus Hypericum sp. has a number of uses in traditional medicine like curing the burns, ulcers, haemorrhoids and wound healing. The species Hypericum lydium Boiss. (Hypericaceae), however, has not been known to have any properties related to the healing of injuries or antimicrobial working against the oral microorganisms. The present study was aimed to evaluate the efficiency of H. lydium in soft tissue healing and its capacity to prevent infections after dental extraction. H. lydium was extracted with ethanol and the obtained extract was tested for its inhibition ability on extracellular matrix-degrading enzymes; collagenase, hyaluronidase and elastase. To determine the cytotoxicity and wound healing capacity of the extract, MTT and in vitro scratch wound healing assay were performed using the NIH-3T3 fibroblast cells, respectively. Antimicrobial activity was investigated by microdilution method against oral pathogenic microorganisms. The highest enzyme inhibition activity was determined against elastase (80.27±0.1%). According to the cytotoxic activity results, the IC50 value of the H. lydium was found to be 82.20±4.05 μg/mL. Scratch wound healing assay of the extract exhibited a significant enhancement at 24 h with a closed wound area when compared with the control. The extract showed potent antimicrobial properties against oral pathogenic microorganisms. The results of the study revealed out that H. lydium can be considered as a natural compound for dental industry to improve soft tissue healing and to prevent the possible infections after dental extraction.

Does Agricultural Support Policy Affect Crop Production in Turkey?
Authors: CANBAY Şerif
Published: May 2021

One of the most basic requirements of humanity is the need for nutrition. Therefore, the demand for food products that do not have a substitute for human life is quite heavy. To this end, the agricultural sector becomes prominent to meet the need for nutrition but puts economic units in a great search. In this context, the agricultural sector is an important dynamic of the country’s economies. This study seeks to answer how support and incentives for the agricultural sector affect agricultural crop production. In this context, the ARDL bounds test with a structural break was conducted using Turkey’s 1995-2018 data to determine the effects of agricultural supports on agricultural crop production. According to the analysis results, it was found out that agricultural supports in Turkey positively affect agricultural crop production in both the short and long term.

Mračna Tetrada je psihološki koncept koji opisuje amoralnu i antisocijalnu strnau ljudske ličnosti pomoću četiri crte - Makijavelizma, narcizma, psihopatije i sadizma. Cilj ovog istraživanja bio je ispitati vezu između dimenzija Mračne Tetrade ličnosti, nepovoljnog sredinskog okuženja tokom razvoja i konzumacije psihoaktivnih supstanci (PAS). Korišćenjem “online“ ankete u prikupljen je uzorak od 239 ispitanika (55.65% ženskih ispitanika). Rezultati su pokazali da je psihopatija najvažniji prediktor upotrebe PAS-a jer nezavisno pozitivno predviđa sve ispitivane klase psihoaktivnih supstanci. Narcizam je pokazao nezavistan pozitivan doprinos pri predikciji konzumacije cigareta i kanabisa ali i ukupne mere upotrebe supstanci. Makijavelizam i sadizam su imali pozitivne korelacije sa nekim od ispitivanih kriterijuma ali ne i nezavistan doprinos u regresionim modelima što znači da se detektovane bivarijantne asocijacije mogu svesti na relacije između drugih mračnih crta i konzumacije PAS-a, najverovatnije psihopatije. Nisu pronađene veze između nepovoljne sredine i kreterijumskih varijabli kao ni interakcije mračnih crta i sredine pri predikciji. U radu se diskutuju implikacije nalaza uzimajući u obzir i ograničenja samog istraživanja.
