In this study, a method was proposed for correcting the object positioning error of light detection and ranging (LiDAR) due to the roll, pitch, and yaw data error of the inertial measurement unit sensor in the global navigation satellite system (GNSS) sensor by using a high-precision digital map. A real-time obstacle map was formed using Velodyne’s three-dimensional lines, VLP-32 and VLP-16. The high-precision digital map was then merged into the LiDAR map. The map obtained by combining LiDAR and high-precision digital maps did not match because of certain errors. To eliminate these errors, a method of fitting a map with high precision on the XY plane was established, and fittable criteria were determined. Algorithm verification was performed during actual driving, and errors were removed in real time. Various autonomous driving technologies can be developed using the sensor error data preprocessing process.

Objectives : This study is to evaluate the awareness, attitude, practice and the countermeasures against passive smoking in Korean adults. Methods : By self-administered questionnaires, we assessed the knowledge, attitude, behavior for passive smoking and the countermeasure for reduction of it's harmful effects in 289 men and 238 women. Results : The subjects that have heard about passive smoking were 96.8% in total and well known were 26.4% of current smoker, 56.6% of ex-smoker, and 14.8% of non-smoker(p=0.001). The irritative symptom from passive smoking was the most frequent in non-smokers and the most common place where exposed to passive smoking was public place. For attitude against passive smoking in 'no smoking allowed area', ex-smokers were the most active to recommend to stop smoking. And for opinion about establishment of 'no smoking allowed area', the restriction by law was the best acceptable method in smokers, exsmokers, and nonsmokers. In marking of 'no smoking allowed area', 69.9% of smokers answered no smoking, but in non-marking area only 6.3% stop smoking. When smokers were recommended to stop smoking, the more subjects stop smoking with good feeling in marking area, but the less in non-marking area. The factor associated the high awareness of passive smoking were aged(OR=1.07, 1.03-1.12), men(OR=4.34, 2.32-8.46). The persons who have known well about passive smoking had good attitude and behavior to prevent of harmful effect of passive smoking.

During the development of electronic warfare support (ES) equipments, it was required to come up with an objective and quantitative test methods in order to verify the performance of an equipment. Although there are a variety of verification methods available, reliable and proven measurement equipments should be used first in order to validate an objective test and assess the developed equipment. In this study, we used a commercial instrument, the Agilent's Pulse Analyzer, to analyze the general performance of an ES equipment. Naturally, commercial instruments have production features that do not support the use of evaluation. Agilent's Pulse Analyzer also has some performance limitations for the use of testing an ES equipment. Because of this, we developed a new software to overcomes the constraints of the Pulse Analyzer. Also, a reliable assessment method is proposed to test the developed ES equipment.

In this paper, the concept of environmental efficiency is examined for power industry using power sector information from year 1986 to 2007. First, we define environmental efficiency and then apply DEA(Data Envelope Analysis) model of CCR (Charnes, Cooper, and Rhodes, 1978) and BCC(Banker, Charnes, and Cooper, 1984). Our finding suggests that the performance of power industry is the most efficient in the year 2007 in both models of CCR and BCC. Taking this specific year’s performance to be a point in frontier, required reduction to accomplish that efficiency of CO2 emission and of transmission and distribution losses are also calculated. Results of analysis shows that it requires further examination of the measurement of environmental efficiency of power sector since the measurement results differ depending upon the assumptions on the returns to scale, although current trend shows a continuous improvement in both scale efficiency and technical efficiency.

As a core policy for achieving the goal of reducing greenhouse gas emissions in the building sector, Korea has enforced the mandatory certification of zero energy buildings for new public buildings from 2020. This study suggests energy-saving technologies and economic factors that building officials can refer to for decision-making on the implementation of zero energy buildings. For this study, the construction cost for the energy item of a building was analyzed by collecting the building energy efficiency level certification data and detailed construction cost statement data from public institutions for the last three years. Based on the building energy efficiency certification data, each energy item of the baseline building was derived, and the energy performance of the zero energy building was derived through repetitive simulations by gradually increasing the energy performance value of the baseline building. By applying the analyzed construction cost, the construction cost for each energy item of the baseline and zero energy buildings was derived. As a result, the lighting equipment contributed up to 10.5% energy savings, and the increase in construction cost of the cooling and heating system was at least 9.1%.

As a key policy for achieving the goal of reducing GHG in the building sector, Korea has enforced the mandatory certification of zero-energy buildings for new buildings in the public sector from 2020. This study evaluated a policy to achieve Net Zero by identifying the trend of changes in building energy performance according to policy and presenting a methodology to analyze the current performance state of energy technology applied to buildings. The final goal was to help stakeholders apply appropriate energy technologies for new buildings. For this study, data collected on building energy efficiency certification over the last four years have shown a gradual increase in energy performance. In addition, K-means cluster analysis was used to analyze the performance status of energy technologies applied to buildings. The high and low clusters of education and office facilities were used to analyze the comparative group (2016-2020, 2020). As a result, the solar module area in both high and low clusters of education facilities increased by 261.1% and 283.5%. In contrast, the solar module area decreased by both high and low clusters of office facilities. The most passive and active technologies showed an increase in energy performance.

This paper purposes on the development of energy management framework, focusing on the superstores in South Korea. Those superstores are usually huge retail outlets, operating for a long time, and thus requires a large amount of energy consumption. Nevertheless, few attempts have been made to identify the energy management issues in the superstores and to propose the way to improve their energy management systems. To meet this needs, we firstly analyzed the over trends of energy use in South Korean superstores using various energy efficiency indices. Then, on two stores chosen as our case targets, in-depth analysis was carried out in terms of their current energy use and capabilities to reduce the energy use. The research findings are expected to support energy manager’s strategic decision-makings at the firm level and further to contribute to the CO₂ reduction at the national level.
