Detecting and Rectifying Vehicle Malicious Misbehavior for Intersection Movement Assist: A Sensor-Based Misbehavior Detection Study

Recent developments in wireless communication technologies have led to the evolution of connectivity between vehicles. Maintaining connectivity between vehicles increases a vehicle’s awareness of other nearby vehicles, which can be used in safety applications. Identification of malicious misbehaving vehicles plays an important role in road safety. This research establishes the minimum detectable error (MDE) boundary for relative position between the observer and status vehicles (SV) using vehicle sensor and GPS error profile from field tests and established minimum standards. The results demonstrated that the MDE increases in the lateral direction (side-to-side) with the increase in relative distance between the observer and status vehicles (OV and SV) while remaining the same in the longitudinal direction (front-to-back). This research effort explores the use of Sensor-Based Misbehavior Detection (SBMD) with current specifications and the defined MDE boundary for implementation in the Intersection Movement Assist (IMA) safety application to rectify false positive and false negative hazard messages propagated by a malicious misbehaving vehicle. The simulation approach used in this research quantifies the total number of false positive/negative hazard detections received by a third-party vehicle (TPV) using the IMA safety application and assesses the capability of the OV equipped with SBMD to rectify the false positive/negative hazard detection. In cases where there was no hazard, SBMD produced an 83% to 90% improvement in the reduction of false positive hazard detections. In the cases with hazard scenario, where the SV is in the not-safe-to-cross zone, SBMD produced an 80% to 99% improvement in application performance.

Aplikasi Keselamatan Berbasis Smartphone dengan Integrasi Sinyal Sos Sebagai Solusi Pembentukan Masyarakat Tanggap Bencana

Natural disasters are disasters caused by an event or a series of events caused by nature, it’s as varied as the form of earthquakes, tsunamis, volcanic eruptions, floods, droughts, hurricanes, and landslides (Law number 4 of 2007). Based on data cited from the Indonesian Central Statistics Agency (BPS) in 2018 the number of people who died due to natural disasters was 6,053 people. This data shows that community preparedness to face the threat of disaster optimally is needed. The idea of creating a smartphone-based safety application design equipped with SOS signal sending capabilities is planned to create a disaster response community and rescue response by related parties to reduce disaster risk with the use of the structured application. The synergy between various parties such as the community and also the government in the smooth running of information as quickly as possible will be the key to the effectiveness of this application. People in situations facing natural disasters can reach safe places with the help of an application that has been embedded in the feature to find out safe places for self-evacuation. If there is an emergency the user can also send an SOS signal to the server which will be picked up immediately by the patrol on duty.

Hubungan sikap perawat dengan penerapan patient safety pada masa pandemi Covid 19

Clinical nurses' attitude toward patient safety: application and results during Covid 19 pandemicBackground: Patient safety is an effort to reduce unnecessary injuries associated with health care to the minimum acceptable level. Patient safety incident report in Indonesia in 2009 were 114, 103 incident in 2010, 34 incident in 2011. The number of adverse events was 10.5% and a near miss incident was 6.15%.Purpose: known that relationship between nurses' attitude with patient safety application during the Covid-19 pandemic at public health center Pesawaran district in 2020.Method: A quantitative study by survey analytical with cross-sectional design. The sampling technique using a questionnaire and taken by total sampling. The respondents of 40 clinical nurses at public health centre.Results: Respondents who had positive attitudes were 32 (80%), and who had negative attitudes was 8 (20%). Respondents who had behavior of patient safety standard application with good categories were of 20 (50%), and respondent with a poor category was of 20 (50%) and based on the statistical result of (p value 0,008; OR=15,000).Conclusion: There are relationship between clinical nurses' attitude toward patient safety: application and results during COVID-19 pandemic at the health center. Suggestions for health centre management to pay attention for patient during covid-19 pandemic and all staff nurses to follow the health protocol for Covid.Keyword : Clinical nurses; Attitude; Patient safety; Application; Covid-19 pandemicPendahuluan: Keselamatan pasien merupakan sebuah upaya menurunkan cedera yang tidak perlu yang berhubungan dengan pelayanan kesehatan hingga ke tingkat minimum yang dapat diterima. Laporan insiden keselamatan pasien di Indonesia tahun 2009 sebanyak 114, tahun 2010 sebanyak 103, tahun 2011 sebanyak 34. Angka Kejadian Tidak Diharapkan (KTD) sebesar 10,5% dan Kejadian Nyaris Cedera (KNC) sebesar 6,15%.Tujuan: Diketahui hubungan sikap perawat dengan penerapan patient safety pada masa pandemic covid 19 di UPT Puskesmas Rawat Inap Kabupaten Pesawaran Tahun 2020.Metode: Penelitian ini menggunakan desain penelitian Survey Analitik dengan menggunakan rancangan cross-sectional. Teknik pengambilan sampel dalam penelitian ini menggunakan lembar kuesioner. Populasi dalam penelitian ini adalah seluruh perawat puskesmas rawat inap yang berjumlah 40 responden.Hasil: Responden yang mempunyai sikap positif sejumlah 32 (80%) dan responden dengan sikap negatif sejumlah 8 (20%). Responden yang mempunyai perilaku penerapan standar keselamatan pasien dengan kategori baik sejumlah 20 (50%) dan responden dengan tingkat perilaku tidak baik sejumlah 20 (50%). Uji penelitian yang dilakukan menggunakan uji chi square dengan hasil (p value 0,008; OR=15,000).Simpulan: Ada hubungan sikap dengan penerapan patient safety pada masa pandemi covid 19 di UPT Puskesmas Rawat Inap Kabupaten Pesawaran tahun 2020. Saran dari peneliti ini diharapkan untuk selalu menerapkan standar keselamatan pasien dalam pelayanan.
