Accommodation Rock after Visual Display Unit (VDU) Activity under Two Different Ambient Lightings

Dynamic accommodation under natural viewings, such as driving, could be affected by the lighting condition. This study aimed to investigate the accommodation rock after the visual display unit (VDU) activity with and without ambient lighting. It was measured in cycle minute (cpm) with Hart Chart before and after each lighting condition's VDU activity. The VDU activity involved a one-hour visual task in 30 young adults. There was significant different [c2(3) = 23.42, p<0.001, Friedman test] in accommodative rock with VDU activity under different lightings. Low lighting lowered the rapid change of accommodation at different distances under natural viewing.

SISTEM SECURITY JARINGAN ETHERNET PADA PROTOTYPE STASIUN KERETA API YANG TERINTEGRASI DENGAN INTERLOCKING

Pada saat ini, pembangunan berkembang lebih cepat khususnya pada bidang transportasi salah satunya perkeretaapian. Salah satu sektor yang penting dalam pelayanan kereta api adalah sistem persinyalan kereta api. Sistem ini mengatur lalu lintas perjalanan kereta api yang berfungsi untuk memastikan kelancaran perjalanan kereta api dan menghindari terjadinya kecelakaan. Saat ini kebanyakan meja pelayanan yang digunakan adalah meja pelayanan jenis Local Control Panel. Namun saat ini sudah ada meja pelayanan berbasis komputer yang umum disebut dengan meja pelayanan jenis visual display unit (VDU). Teknologi saat ini telah berkembang cukup pesat dan banyak ditemukan alat-alat inovasi terbaru sehingga tidak menutup kemungkinan bahwa nanti akan ada pihak yang akan menyalahgunakan hal tersebut. Untuk menangani hal tersebut dibutuhkan pengamanan sistem dari VDU tersebut baik dari data base dan keamanan jaringan yang dipakai. Maka dilakukanlah pembuatan sistem security pada VDU yang dapat membantu mengamankan komunkasi VDU yang di implementasikan pada prototype interlocking base compute. Sistem ini dibuat menggunakan metode whitelist, menambahkan ip pada tiap tiap ethernet shield dengan menggunakan telnet dimana ethernet shield sebagai client dan data base sebagai server untuk keamanan tambahan ditambahkanya (secure hash algorithm) SHA 256 pada password untuk tambahan pengamanan komunikasi. Dari hasil pengujian terhadap program yang sudah dibuat, dapat diambil kesimpulan bahwa sistem security jaringan ethernet ini dapat membantu mengamankan jaringan komunikasi. Sistem ini hanya dapat digunakan pada prototype interlocking base computer.

Electronic Vaccine Monitoring System

In today’s world we tend to face with many several different types of emergencies within the indoor atmosphere. Response to such emergencies is important so as to shield resources together with human life and additionally we will save property from harm. During these Paper, we tend to gift wireless sensor network for Temperature observation. Which might report the emergency to the users in numerous forms, like as pop-ups on a visual display unit, SMS on their cell phones and then on. Because of this flexibility of coverage low value wireless sensor network ready for emergency response system of future. During this paper we tend to develop three wireless sensor nodes and that we need to place in numerous positions within the building and we need to inform to the master node or observation node regarding the temperature on the market at every sensor node. And that we additionally planning to specialize in wireless temperature observation and controlling the vaccine temperature.

Widget-based Alarm Recognition and a Management Support Interface System in Nuclear Power Plants

As small modular reactors (SMRs) and various computerized operating support systems have been developed, visual display unit(VDU)-based multifunctional consoles have been proposed. The more a console depends on VDUs, the more human system interface (HSI) designers need to consider the decrease in the human performance caused by the effect of navigation tasks. This paper proposes a widget-based alarm recognition and management support interface system to increase the operator’s ability to recognize alarms and to manage alarm-related tasks by reducing additional and excessive navigation tasks. With a small display screen, the system provides operators with quick and accurate access to alarm-related information and allows them to make corrective responses.
