Smoke is the real threat in a fire in an enclosed, underground parking garage, and is a significant issue and very critical for firefighters dealing with fire. Special attention should be paid to fire safety, especially for those with multiple floors underground. A model of the smoke movement in a basement was established using Fire Dynamics Simulator (FDS) 6.0 software. In this paper, the study undertaken used a basement model of 60 m (length) × 30 m (width) × 3 m (height) and has three typical floors. Smoke ventilation shafts were provided for the basement. A well-controlled liquid pool fire with a heat release rate (HRR) of 2 MW was used as an input parameter. The ventilation strategy was achieved through a mechanical exhaust fans and makeup air fans. The required ventilation was based on the air changing ten times per hour. The following parameters were varied: the location of the fire, the presence or absence of sprinklers, the presence or absence of a smoke-extraction system, the presence or absence of openings for incoming air, and the presence or absence of a jet fan and ducting. The impact of jet fans (induction type) was also addressed in several simulations. Smoke modeling was investigated under different fire scenarios. Simulations were conducted for smoke and heat control using forced, mechanical, horizontal ventilation. When the combination of a jet fan and ducting was applied, the fastest time for smoke removal was achieved compared to the other scenarios.
Dampak media sosial pada komunikasi politik merupakan topik yang menjadi sebuah fokus dalam studi kampanye politik. Studi ini bertujuan untuk mengetahui apakah ada peranan dari media sosial dan media massa dalam agenda setting yang dilakukan oleh politikus dalam komunikasinya di media sosial di berbagai negara. Teori agenda setting adalah topik yang dieksplorasi dengan baik dalam teori efek media, maupun kreasi media. Lima studi terdahulu yang diteliti pada studi ini memiliki kesamaan pada aspek menggunakan media sosial sebagai media pendukung proses agenda setting. Dari lima studi kasus yang direview dapat dilihat bahwa ada keterkaitan era tantara agenda setting dan media massa. Mayoritas dari studi kasus yang diteliti menggambarkan keadaan yang serupa dengan penelitian terdahulu mengenai agenda setting, studi menunjukkan bahwa kebangkitan media baru seperti media sosial mengubah arus komunikasi dan juga arah komunikasi politik. Proses agenda setting dalam proses kampanye atau pemilihan terjadi dihampir seluruh negara, baik hal itu terjadi secara masif dan gamblang, maupun secara tertutup dan tidak massif. Dan media mainstream memiliki peranan tersendiri dalam setiap proses agenda setting.
