산업통상자원부(장관 주형환)가 지난 6월 16일 '액화석유가스의 안전관리 및 사업법' 제45조, '도시가스사업법' 제17조4항의 상세기준 개정안을 승인 공고하고 가스계량기 설치장소 환기 양호 기준을 합리화했다. 이전에는 '사람이 거주하는 건축물 세대 밖(복도, 계단 등)의 경우 창문 등을 열어 환기를 할 수 있는 장소'로 규정했지만 이번 개정을 통해 '환기가 가능한 창문 등(개방 시 환기면적이 $100cm^2$ 이상에 한한다)이 설치된 장소'로 완화했다.

Conventional window cleaning method has a number of limitations, for example, workers dependent and high crash risk. The purpose of this study is to derive the performance requirements of a window cleaning apparatus through technology survey. For this, we investigated the domestic and international patents related to window cleaning, and interviewed experts in the field of window cleaning and mechanical design. Through this research, we have proposed performance requirements of the window cleaning apparatus.

This study presents a novel algorithm for determining the P-wave arrival time using amoving window function to improve source localization in low-SNR (signal-to-noise ratio)acoustic emissions. The proposed algorithm was applied to low-SNR signals to verify the accuracy of measurements against existing algorithms. When other algorithms were applied, the test results revealed that SNR decreased and accuracy was reduced, especially where SNR wasless than 2.14. The proposed algorithm using amoving window function considers the frequency characteristic and signal amplitude simultaneously, and produced reliable results where SNR was 2.14.

Function of the window of the building is an environment of the room through the entry of solar radiation. It is vulnerable to significant energy conservation off the thermal efficiency. Also this summer, cooling costs are weighted because of excessive solar radiation. In this paper, we develop a windows automatic control system to use the indoor environmental information, such as home temperature, humidity, light intensity, solar radiation. The system collects the indoor environment information using a variety of sensor, using the collected information, and controls the motor to the system to control the window.

In this paper, we apply the NR (Noise Rating) to the evaluation of the residual noise of the window type ANC (Active Noise Control) and study the active noise controller for minimizing the NR value in rooms. We proposed a shape of a noise shaping filter of the Filtered-E LMS (Least Mean Square) algorithm that reduces the NR value within the effective operating frequency band of the ANC. The usefulness of the proposed scheme is verified by simulation and showed that the NR value of the residual noise is lower than the filters used in the conventional psychoacoustic ANC.
