The tunnel is the place where brightness changes abruptly. It is important to grasp the road situation and the traffic situation of the tunnel accurately for safe and secure driving, and tunnel lighting installation should be well maintained. Luminance and illuminance of the tunnel inside should be measured periodically to maintain enough brightness. But traditional manual measurement could not guarantee the fastness and trustworthy of the measured values. In this paper, a mobile measuring system for tunnel lighting luminance and illuminance was developed and a result regarding the propriety of the system was derived.

In this paper, it is reported that film-bulk-acoustic resonator with high c-axis oriented AIN film on
using metal-organic-chemical-vapor deposition was fabricated. The resonant frequency and anti-resonant frequency of the fabricated resonator were observed with 3.189[GHz] and 3.224[GHz], respectively. The quality factor and the effective electromechanical coupling coefficient(
) were measured with 24.7 and 2.65[%], respectively. The conditions of AIN deposition were substrate temperature of
, pressure of 20Torr, and V-III ratio of 25000. A high c-axis oriented AIN film with
resistivity of Mo bottom electrode and
of AIN(0002) full-width at half-maximum(FWHM) on

Generally, Permanent Magnet Brushless DC Motor(PM BLDC) is necessary the Hall-IC to detect the rotor position. But it will take place the operation standstill of motor or error of rotor position detection according to the circumference temperature, humidity, or limited surroundings. This paper propose the algorithm of rotor position detection only using one or two Hall-IC. Therefore we can estimate information of the others phase in sequence through a rotor instead of using three Hall-IC at 3 phase motor. This paper identify the same characteristics, performance and function of protection circuit by the proposed algorithm with the 3 phase PM BLDC motor in comparison with general method.

This paper presents the transient impedance behaviors according to the length of down conductors of grounding systems to lightning impulse currents. The potential rise and effective impulse ground impedance of the deeply-driven ground rod and grounding grid subjected to the impulse currents were measured and analyzed as a function of the rise time of impulse currents and lengths of down conductor. The transient ground impedances strongly depend on the configuration and size of grounding electrodes, the waveform of impulse currents and the length of down conductors, and the installation methods reducing the inductance of down conductors are an important factor to decrease the transient ground impedances.

A person's body resistance in the waterpark, public bath and similar places is much lower than any other places due to effect of water. So low voltage may create a shock hazard for the human body in case of leakage or fault currents from lighting unit etc. We researched the related regulations which are internal standards, NEC, IEC and investigated the actual conditions for the prevention of electric shock due to lighting units in the waterpark, public bath and similar places. As a results internal standard is obscure as compared with NEC, IEC which is the limit of application and distinction of environment condition. And then internal standard's using voltage is higher than NEC, IEC in filed of water. Studies show that internal standard should be revision that raise the installation height of lighting unit, mark IP level surface of lighting unit and limit using voltage to line-to-line voltage

For the design of DC traction power supply system at new Light Rail Transit(LRT) construction, it is very important to determine system configuration, location and power capacity of substation. However, a LRT system consists of a number of subsystems such as train movement, power supply and traction drives, which inevitably contains many complexities and diversities. The objective of this paper is to clarify and systematize the design procedure and its assessment for the electrification system of a LRT line. This paper discusses in detail our approach to system design and its assessment. The whole DC-feeding network configuration, characteristics of a train, and design method of substation arrangements is thoroughly investigated for the design. As a result of the investigations, the design procedure is clarified and systematized and a computer program for the design and evaluation of the system is developed using the most suitable iterative method with nodal equation. To verify the proposed design and its assessment procedure, case studies for the DC traction power supply system of a planed Korean LRT line are performed.

This paper is proposed an efficiency optimization control algorithm for a synchronous reluctance motor which minimizes the cower and iron losses. The design of the speed controller based on adaptive fuzzy-neural networks(AFNN) controller that is implemented using fuzzy control and neural networks. There exists a variety of combinations of d and f-axis current which provide a specific motor torque. The objective of the efficiency optimization controller is to seek a combination of d and q-axis current components, which provides minimum losses at a certain operating point in steady state. It is shown that the current components which directly govern the torque production have been very well regulated by the efficiency optimization control scheme. The proposed algorithm allows the electromagnetic losses in variable speed and torque drives to be reduced while keeping good torque control dynamics. The control performance of the hybrid artificial intelligent(HAI) controller is evaluated by analysis for various operating conditions. Analysis results are presented to show the validity of the proposed algorithm
