Weak over-the-horizon perception and blind spot are the main problems in intelligent connected vehicles (ICVs). In this paper, a V2V image transmission-based road condition warning method is proposed to solve them. The encoded road emergency images which are collected by the ICV are transmitted to the on-board unit (OBU) through Ethernet. The OBU broadcasts the fragmented image information including location and clock of the vehicle to other OBUs. To satisfy the channel quality of the V2X communication in different times, the optimal fragment length is selected by the OBU to process the image information. Then, according to the position and clock information of the remote vehicles, OBU of the receiver selects valid messages to decode the image information which will help the receiver to extend the perceptual field. The experimental results show that our method has an average packet loss rate of 0.5%. The transmission delay is about 51.59 ms in low-speed driving scenarios, which can provide drivers with timely and reliable warnings of the road conditions.

Environmental stressors considerably influence the health and safety of humans and must thus be continuously monitored to enhance the urban environments and associated safety. Environmental stressors typically act as stimuli and lead to behavioral changes that can be easily identified. These behavioral responses can thus be used as indicators to clarify people's perceptions of environmental stressors. Therefore, in this study, a framework for assessing environmental stressors based on human behavioral responses was developed. A preliminary experiment was conducted to investigate the feasibility of the framework. Human behavioral and physiological data were collected using wearable sensors, and a survey was performed to determine the psychological responses. Humans were noted to consistently exhibit changes in the movement and speed in the presence of physical environmental stressors, as physiological and psychological responses. The results demonstrated the potential of using behavioral responses as indicators of the human perceptions toward environmental stressors. The proposed framework can be used for urban environment monitoring to enhance the quality and safety.

유기용제가 신경행동기능에 미치는 영향을 평가하기 위하여 에탄올을 이용하여 저농도의 유기용제가 신경행동기능에 미치는 영향을 정량적으로 평가하고 신경행동기능 영역중 에탄올에 민감한 기능영역을 선별하기 위하여 실험연구를 시행하였다. 영남대학교 의과대학 학생중 20명을 대상으로 설문조사 및 신경행동학적 검사를 1996년 8월동안 실시하였다. 대상자의 체중 kg당 100% 알코올 0.5g을 섭취하고 개인용 컴퓨터를 이용하여 단순반응시간, 색단어구분, 숫자구분, 손가락두드리기, 숫자더하기, 부호숫자짝짓기, 숫자외우기를 시행하였다. 알코올 섭취 전과 후의 신경행동기능의 변화량은 단순반응시간(반응시간 237.4 : 269 msec, p<0.01), 숫자구분(반응시간 490.4 : 553.9 msec, p<0.01), 우수의 손가락두드리기(반응시간 66.7 : 63.3, p<0.05)와 부호숫자짝짓기(반응시간 1958.7 : 2066.6 msec, p<0.05)에서 통계적으로 매우 유의하였다. 평소 음주량이 많을수록 단순반응시간, 열수의 손가락두드리기, 부호숫자짝짓기에서는 반응시간이 길어지고, 우수의 손가락두드리기에서 두드린 수가 적어지는 경향을 보였다. 흡연량이 많을수록 열수의 손가락두드리기에서 두드린 횟수가 증가하는 경향을 보였다(p<0.05). 알코올의 급성폭로 후 나타난 결과로 만성적 폭로의 영향을 평가하는데 이용하기에는 다소 무리가 있으나 향후 유기용제의 만성효과에 관한 역학적 연구를 위한 신경행동학적 검사항목의 선택에 도움을 줄 수 있을 것으로 생각된다.

우리나라 경찰은 차량순찰을 중점적으로 실시하고 도보순찰 및 오토바이 순찰을 병행하여 활용하고 있으나, 오토바이 순찰은 차량순찰과 도보순찰의 장점을 혼합한 것이어서, 오토바이 순찰을 효과적으로 활용한다면 순찰범위를 더욱 확대하고 지역주민과의 친밀성도 증진시킬 수 있다고 여겨진다. 이 연구의 목적은 경찰 오토바이 순찰활동의 주요요소들 중에서 어떤 요소들이 그 효과성 인식에 통계적으로 유의미한 영향을 미치는지를 살펴보고, 분석 결과에 기초하여 경찰오토바이 순찰활동의 효과성 인식을 향상시킬 수 있는 방안들을 제안하는 것이다. 이 연구는 2013년 9월에 오토바이 순찰활동을 집중적으로 실시했던 대전지방경찰청에 근무하는 경찰관 139명을 대상으로 조사하였고, 독립변수로는 경찰관과 주민간 친밀성, 순찰장비의 우수성, 대응의 신속성, 순찰방법의 적절성이라는 4개 변수가 선정되었으며, 종속변수는 경찰 오토바이 순찰활동의 효과성 인식이다. 회귀분석의 결과, 종속변수인 경찰 오토바이 순찰활동의 효과성 인식에 통계적으로 유의미한 영향을 미치는 독립변수는 대응의 신속성, 순찰방법의 적절성, 순찰경찰관과 주민간 친절성 3개 변수인 것으로 나타났다. 따라서, 이 연구의 분석결과에 기초해서, 경찰 오토바이 순찰활동의 효과성 인식을 향상시키기 위해서는, 대응의 신속성을 증진시키고 순찰방법의 적절성을 향상시킬 수 있는 방안을 마련하고, 순찰경찰관에게 주민간 친절성의 가치를 인식시킬 필요가 있다.

The purpose of this article is to examine the 'Discussion of maritime defense' which began to be discussed from the late Goryeo dynasty to the early Joseon dynasty and the process of establishing a maritime defense system. Also it can identify changes in the aspects of the naval ship operation and their strategic tactics during the reign of King Sejong. Japanese raiders began a full-scale invasion from 1350 at the late Goryeo Dynasty, So the government realized the need to raise the 'Sea power' and to organize the maritime defense system for defending enemy invasion. for example, the reinforcement of naval forces, construction of warships, develoment of weapon systems and so on. which have achieved remarkable growth while continuing, have also been used to carry out a three-time 'Conquest of Daemado' in 1389, 1396, 1419. Until then, however, it is difficult to interpret that the naval forces had a systematic and organizational combat operation system. According to fighting patterns on combat reports before the early days of King Sejong's reign, Our naval forces had no advantage over the Japanese raiders in terms of their capabilities and tactics. Then, the period of King Sejong marked a watershed in maritime defense history. Based on accumulated experience of naval battles and force Projections, The paradigm shift of the naval strategic tactics for maritime defense has occurred. First, the capability of the naval vessels has improved. for example, ship speed, durability, and weather resistance. Through these efforts, navy forces were able to pursue and attack, destroy enemy's ships by taking advantage of the 'Ship speed superiority'. This has led to tactical shifts from defensive to offensive. Second, purpose to support offensive tactics, the government put a strategic plan into practice that is the forward depolyment of naval bases from the inland to the coast, considering the 'sea environment' and 'threat'. By doing so, Joseon dynasty was able to secure 'the command of the sea'. This may be a little different from the perception of the so-called 'peace period' that King Sejong's era. We need to remember that Joseon dynasty was working hard for its defense. When studying history of maritime defense, these strategic and tactical elements must be fully considered. Only then we can have a coherent understanding of the many naval battles in the past, including the Imjin War(1592-1598).
