The objective of this study is to prepare a proposal for desired changes in the laws and regulations system of the Environmental Impact Assessment (EIA) about cultural assets preservation. The related Korean regulatory system and literature for EIA have been surveyed and case studies have been analyzed and actual cases where cultural assets protection were of issue have been studied to deduce the problems of those areas. Based on the result of this study, proposed changes are as follows; 1. "Status of cultural Assets" is to be included as common assessment factor for all categories of object projects in "Table 2: Essential Assessment Factors for Individual Project Category" of "Ordinance for Preparation of EIA Statement, etc." 2. "Status of Underground Cultural Assets and Potential Underground Cultural Assets" is to be inserted as a survey factor in "Table 3:Format of and Instruction for Impact Statement". 3. The clause of "-- the survey should be performed on-site and the investigation report should be submitted." is to be inserted in methods of survey in "Table 3". 4. Ground survey of cultural assets should be performed prior to completion of project planning, that is, from the stage of pre-study for site selection. 5. The application of impact abatement from "Methods and Plants for Impacts Abatement" of "Report for Development of EIA Statement Technologies" should be included, with proper modification of timing, in "Ordinance for Preparation of EIA Statement, etc." 6. The expense liability clause in "Cultural Assets Preservation Act" is to be revised as "a certain ratio of expenses for excavation should be borne by the government." 7. Regulatory device for collecting appropriate opinions should be established. It may include Cultural Assets Preservation Committee's hearing to the project owner's opinion. be established. It may include Cultural Assets Preservation Committee's hearing to the project owner's opinion.

Workers engaged in construction works have been exposed to high levels of noise during their work in tunnels. Noise is one of the major health hazards for employees working in construction sites. The aim of this study is to evaluate the noise levels generating from tunneling equipments such as jumbo drills, backhoes, payloaders, shotcrete machines and service cars. Explosion and turbo fan noises were also monitored. A high precision sound level meter was introduced for measuring LAeq, LAFmax, LAFmin and LCpeak noises in 5 tunneling work sites that were located in Seoul, Kyunggi-do and Kangwon-do areas with NATM and shield methods. The highest noise was recorded by explosion(151.9 dB LCpeak) followed by jumbo drills of higher than 110 dB(A) LAeq. Backhoe normally generated 90~110 dB(A) LAeq while breaking work of rock showed additional around 5~15 dB(A). Noise exposure levels for payloader and shotcrete machine scored more than 90 dB(A) which might be a source of noise-induced hearing loss. Additional research in revealing noise levels from construction equipments operating in tunneling works may enhance the protection of workers who exposed to noise primarily at the sites.

The indoor noise of the naval vessel is very important considering hearing protection, improvement of working environment and easily communication between crews. When the environment of the naval vessel suffering from the noise is considered, it is very important to be quiet in the living area where the crews have a rest sufficiently. In addition, the noise of the working area should be reduced in order to increase working efficiency. Therefore, in this research, the satisfactions about the indoor noise are survey for crews working in a naval vessel. Through this survey, the relationship between the indoor noise and crew's satisfaction about it can be found. As a result, the limit of sound pressure level which almost all crew can be satisfied with the indoor noise about their living and working area is suggested base on the survey in this research.

This paper is a system that visually informs the hearing impaired to visit other people by blinking the light of a room using the IoT(Internet of Things) technology. The system combines the power of home-use lights with low-power IoT devices to provide visual notifications. Using a current sensor, this system can track user location and then turns on and off the light in that room only to save energy. The proposed idea can create a society that is equal to everyone and can live more conveniently.

Objectives: The main purpose of this study was to assess firefighters' daily personal noise exposure and explore noise levels related to specific tasks and their contributions to total noise exposure using 24-hour full-shift noise exposure measurements with task-based data. Methods: Noise exposure was assessed for eight firefighters (two rescuers, two drivers, and four suppressors) using time-activity diaries. We collected a total of 24 full-shift personal noise sample sets (three samples per a firefighter). The 24-hour shift-adjusted daily personal noise exposure level (L_ep,d), eight weekly personal noise exposures (L_eq,w), and 40 task-specific L_eq values (L_{eq activity}) were calculated via the ISO/NIOSH method. Results: The firefighter noise-sample datasets showed that most firefighters are exposed to noise levels above EU recommended levels at a low-action value. The highest noise exposure was for rescuers, followed by drivers and suppressors. Noise measurements with time-at-task information revealed that 82.3% of noise exposure occurred when checking equipment and responding to fire or emergency calls. Conclusions: The results indicate that firefighters are at risk of noise-induced hearing loss. Therefore, efforts at noise-control are necessary for their protection. This task-specific noise exposure assessment also shows that protective measures should be focused on certain tasks, such as checking and testing equipment.

Construction workers experience a high rate of fatal incidents from mobile equipment in the industry. One of the major causes is the decline in the acoustic condition of workers due to the constant exposure to construction noise. Previous studies have proposed various ways in which audio sensing and machine learning techniques can be used to track equipment's movement on the construction site but not on the audibility of safety signals. This study develops a novel framework to help automate safety surveillance in the construction site. This is done by detecting the audio sound at a different signal-to-noise ratio of -10db, -5db, 0db, 5db, and 10db to notify the worker of imminent dangers of mobile equipment. The scope of this study is focused on developing a signal processing model to help improve the audible sense of mobile equipment for workers. This study includes three-phase: (a) collect audio data of construction equipment, (b) develop a novel audio-based machine learning model for automated detection of collision hazards to be integrated into intelligent hearing protection devices, and (c) conduct field experiments to investigate the system' efficiency and latency. The outcomes showed that the proposed model detects equipment correctly and can timely notify the workers of hazardous situations.

현대범죄의 특징인 지능화, 광역화, 폭력화 등의 범죄 형태에 효율적인 범죄예방 및 진압을 하기 위한 방안의 하나인 기계경비시스템을 이용한 공공장소에서 CCTV의 감시는 일상생활에서 널리 사용되고 있다. 이는 급속히 발달하고 있는 과학기술을 이용한 경찰활동으로 증가하는 범죄사건을 효율적으로 대응할 수 있는 대안점이기도 하다. 그러나, 이러한 CCTV의 폭넓은 활용은 범죄예방이라는 긍적적인 점과 시민의 기본권 침해라는 양자간의 가치가 충돌하는 문제가 발생되고 있다. 공공부문에 있어서 경찰의 CCTV활용은 그 효과성에 대한 명확한 논의가 계속되고 있음에도 불구하고 계속적으로 증대하고 있다. 이것은 시민의 기본권에 대한 침해의 소지가 많아 생겨날 수 있다는 것이다. 기본권의 침해는 쉽지만 그 회복은 많은 비용과 시간이 투입되어야 한다. 또한, 현재 한국에서는 CCTV 운용에 대한 구체적인 법적 규제도 없는 현실에서는 자칫 시민의 기본권 침해에 대한 사실을 무감각하게 만들 수 있다는 것이 문제가 될 수 있다. 본 연구에서는 경찰의 CCTV활용에 대한 선행연구를 기초로 한 법적 문제점, 설문조사를 통한 인식적측면을 고찰하고, 선진국들의 CCTV활용에 대한 현황을 기초로 하여 법적측면과 인식적측면 운영적측면을 중심으로 한국 경찰의 CCTV 운영에 대한 개선방안을 제시하고자 하였다.

디지털 워터마킹 기술은 멀티미디어 데이터에 적용하여 소유물에 대한 불법 복제나 소유자의 저작권 보호 문제를 해결할 수 있는 방법 중의 하나이다. 그렇지만 디지털 영상, 비디오, 그리고 오디오와 같은 멀티미디어 보호 문제를 해결하기 위해서는 여전히 소유권 주장 방법에 대해서 극복해야할 문제점을 가지고 있다. 본 논문에서는 저작물 소유자의 음성신호(Audio signal)를 음성로고(Audio Logo)의 워터마크로 변환하고, 원 영상 내 픽셀 농도 값의 비선형적 특성를 이용하여 음성로고를 공간 영역에서 삽입한다. 그리고 추출된 음성로고를 음성신호로 변환하여 청각적으로 소유자의 음성신호를 스피커로 출력하여 소유권을 주장하는 방법을 제안한다. 실험 결과를 통해, 본 논문에서 제시하는 알고리즘이 일반적인 영상 처리나, 특히 손실 JPEG 등과 같은 다양한 공격에 대해서 강인성을 유지시킬 수 있어 음성로고를 이용해 저작물 보호를 확인할 수 있음을 검증하였다.
