The Design of Accident Detection and Tracking Systems on Motorcycles

Motorcycles are type of vehicles with the highest accidents percentage every year. The location away from the settlement and the time of the accident is one of the factors that slow down the spread of information about accidents. This study aims to make a tool that can send such information in the form of notifications and crash site points to the victims’ families. Testing was conducted by looking at the sensor response detecting tilt on the motorcycle against the large reading angle. Furthermore, GPS module accuracy testing is conducted in reading the location by comparing GPS module readings with actual location points in Google apps Maps which is then calculated by using the Haversine Formula method up to gsm module capability testing for send SMS notifications in the form of latitude, longitude, and links that can connect to the Google Maps app. Based on the results of the trials and analyses that have been conducted, the slope sensor response area to transmit crash notification is <=50° or >=50°. After that, the GSM module will send notifications and location points detected by the GPS module with an average reading difference of 2.97 meters.

Sistem Otomatis Pompa Air dan Sabun pada Wastafel Pencuci Tangan

Washing hands is an activity that should be routinely carried out by every individual, especially during the COVID-19 pandemic like today. There are many factors that make someone feel lazy and don't want to wash their hands, one of which is not wanting to be bothered by hand washing activities such as taking soap, turning the faucet and others. Experiments have been carried out in the form of testing the response of the sensor to detect the user's hand based on the distance and the reading angle. Furthermore, the ability to set the delay time for rubbing hands is tested to activate the water tap pump for rinsing. Based on the results of trials and analyzes carried out, the sensor response is obtained at a minimum distance of 4 cm and a maximum distance of 140 cm with a view or response area of 1100 horizontal positions and 850 in the vertical position. The water pump and soap pump are active for 3 seconds when the user's hand is detected by the sensor approaching the end of the water tap. The water tap pump comes back on after being delayed for 23 seconds, and the system is able to operate 100% automatically. Thus the minimum time for users to rub their hands for 20 seconds according to health standard protocols can be met.

Evaluation of Tourist Services in the Szczecin Landscape Park Puszcza Bukowa (Poland): a Study Based on Tourism Surveys

The article attempts to assess the state and directions of development of tourist services in the area of the Szczecin Landscape Park Puszcza Bukowa (SLP PB) and the directions of their development. The article presents the preliminary results of surveys conducted in 2019 using the PAPI method in the SLP PB area as part of the international REGE project. The survey involved 311 respondents visiting the SLP PB area. The main motivation for the visit (86%) of the respondents in SLP PB is leisure and recreation, and visitors spend time primarily on walking (49%) and cycling (25%). The vast majority of respondents (79%) are aware that the area they are in is protected. At the same time, only 56% of all respondents correctly defined the form of protection of the studied area as a landscape park, which indicates the need for further educational activities. Although the spontaneous associations of the respondents focused on the natural values of this area, the questions about the advantages and disadvantages of the response area concerned primarily tourist infrastructure, services provided or lack thereof. The respondents pointed primarily to service deficits in the area under study in the scope of: guided tours (23%), events (20%) and lack of tourist information points (15%).

CD276-Positive Circulating Endothelial Cells Do Not Predict Response to Systemic Therapy in Advanced Colorectal Cancer

CD276 can discriminate between tumor derived and normal CECs (circulating endothelial cells). We evaluated whether CD276+CEC is a clinically relevant biomarker to predict response to palliative systemic therapy in patients with metastatic colorectal cancer (mCRC). Samples were prospectively collected from patients with mCRC enrolled in the ORCHESTRA trial (NCT01792934). At baseline and after three cycles of 5-fluorouracil/leucovorin and oxaliplatin ± bevacizumab, CECs were measured by flowcytometry (CD34+CD45negCD146+DNA+; and CD276+). A clinically relevant cut-off value of (CD276+)CECs was determined as 100% sensitivity (and 80% specificity in 95% confidence interval) identifying patients with progressive disease within 6 months. There were 182 baseline samples and 133 follow up samples available for analysis. CEC and CD276+CEC counts significantly increased during treatment from 48 to 90 CEC/4 mL (p = 0.00) and from 14 to 33 CD276+CEC/4 mL (p = 0.00) at baseline and at first evaluation, respectively. CEC and CD276+CEC counts were not predictive for poor response (area under the curve (AUC) 0.53 for CEC and AUC 0.52 for CD276+CEC). Despite numerical changes during therapy, CEC and CD276+CEC counts do not adequately predict poor response to first line palliative systemic therapy in patients with mCRC.

HBcAg distribution predicts virologic response to PEG-IFNα therapy in HBeAg-positive CHB with minimally elevated ALT

Aim: This study evaluated the use of initial Hepatitis B virus (HBV) core antigen (HBcAg) distribution in hepatocytes to predict chronic infection with HBV patients with minimally elevated ALT who can achieve viral response to PEG-IFNα therapy. Materials & methods: HBeAg-positive chronic infection with HBV patients with minimally elevated ALT who were treated with PEG-IFNα were enrolled. Predictive values of initial HBcAg distribution in hepatocytes were evaluated. Results: HBcAg of no-end-of-treatment viral response group was more likely to be distributed in hepatocyte nuclei (p = 0.02) and exhibited a higher degree of HBcAg expression in nuclei (p < 0.0001) before treatment. The degree of HBcAg expression in nuclei might be a better predictor of end-of-treatment viral response (area under the curve: 0.88). Conclusion: Lower HBcAg expressions in nuclei correspond to higher possibilities of patients benefiting from PEG-IFNα treatment.

Quantitative Pretreatment CT Parameters as Predictors of Tumor Response of Neuroendocrine Tumor Liver Metastasis to Transcatheter Arterial Bland Embolization

Purpose: To assess whether parameters on preprocedural CT can be utilized to predict the response of NETLM to transcatheter arterial bland embolization (TAE). Methods: We retrospectively reviewed 135 target lesions from 48 NETLM patients who underwent TAE and with complete preprocedural multiphasic CT. Parameters on preprocedural CT including the longest diameter, mean attenuation value in nonenhanced, arterial, and portal-venous phases were collected from each target lesion. Radiological responses were assessed according to RECIST 1.1. The parameters of responder lesions and nonresponder lesions were compared. Arterial enhancement index (AEI) and portal-venous enhancement index (PEI) were calculated. The predictive function of AEI and PEI on tumor response was analyzed by receiver operating characteristic (ROC) curve. Results: A total of 72.6% target lesions had a partial response. For patients, the objective response rate was 72.9%. Mean attenuation values of responder lesions were significantly higher than nonresponder lesions in both arterial and portal-venous phases (105.36 ± 37.24 vs. 76.01 ± 19.19, p < 0.001; 96.61 ± 24.04 vs. 82.12 ± 21.37, p = 0.002). ROC curve showed that both AEI and PEI were effective in predicting tumor response (area under the curve [AUC] 0.757, p < 0.001; AUC 0.655, p = 0.005). Conclusion: AEI and PEI, parameters from evaluation of CT pretreatment attenuation of NETLMs, could predict response to TAE treatment.

Effectiveness of Dynamic Insertion Scheduling Strategy for Demand-Responsive Paratransit Vehicles Using Agent-Based Simulation

This paper deals with the scheduling of paratransit vehicles. The current scheduling method utilized by paratransit providers is to provide a door-to-door ride for those customers who have made reservations. Thus, the paratransit providers know in advance the pickup and drop-off locations of each customer. Using this information, they are able to determine a route for each vehicle to minimize the total operating costs. In the current scheduling method, vehicles are not allowed to pick up unscheduled customers. This practice often leads to low seat utilization. To address this shortcoming, this paper explores the idea of allowing vehicles to pick up unscheduled customers who are in close proximity to the prescheduled stops (referred to as the dynamic response area or DRA). To this end, this paper develops an agent-based simulation model to evaluate the effectiveness of this strategy. The model was tested using the Chicago network. The results of the simulation experiments indicate that (1) the proposed strategy is able to serve more customers using the same fleet size, and (2) the proposed strategy will not significantly affect the scheduled customers’ in-vehicle travel time.

The effect of fiber-rich milk and equi-carbohydrate snack on glycemic and insulin response and satiety feeling

Background: Additional dietary fibers which can decrease the glycemic response by slowing down digestion whilst maintaining the available carbohydrate content is one approach of healthy diet. This study aimed to compare post-prandial glycemic and insulin response, hunger and satiety feeling after consuming fiber-rich milk compare with equi-carbohydrate food as morning snack in healthy adults.Methods: Cross-over study was conducted on 12 healthy subjects who fulfilled the criteria. Each test food was given after consuming standard breakfast. Venous blood samples for insulin and glucose level were taken before consuming test food, at 30, 60, 120, and 180 minutes after, and plotted against time to generate a curve. Hunger and satiety assessments were taken by visual analog scale (VAS) after each blood sampling.Results: In average, age was 30.8+4.3 years old, body mass index was 20.6±1.6 kg/m2. Seven of twelve subjects were females. There were significantly differences in postprandial glycemic response (p<0.001), insulin response (p=0.045) and hunger feeling (p=0.021) between the two foods. However, postprandial satiety feelings were not different significantly (p=0.357). The glycemic response area under the curve of fiber-rich milk was significantly lower than the equi-carbohydrate snack (p=0.010). Conclusion: Differences in glycemic and insulin response, and hunger feeling between two test foods, suggesting that fiber-rich milk can be used as an alternative snack for healthy adults. Further study is needed for the use of fiber-rich milk as an alternative snack for pre-diabetic patients.
