Among the various cases of fire accident, gas accident which is roost essential have a lot of forms and causes. The quantity consumed of gas is increasing because of increment of gas-using families and variations of gas machinery. The quantity consumed of gas in 2007 was 35078 tons and the average rate of increasement was 9.4%. The amount of gas accident was on the peak at 1995 when 557 accidents occurred in a year. In 2007, 123 gas accidents was occurred and the average rate of diminution was 11.5%. Accidents by LP gas took 80% of the whole accident and city gas and high pressure gas took 20%. In case of LP gas, accidents were usually occurred because of lack of blocking after the removal of gas machinery and moveable butane burner. Especially, the accidents cause by carelessness of a provider is increasing. Gas accidents which generate damage of human life and property, are caused by users' carelessness, providers' carelessness, inferiority of structure and old products. In this thesis, We will classify the gas accidents. Furthermore through the classification of accidents by forms, causes and regions, this thesis going to be a reference to understand and prevent the accidents.

In this paper, 2513 marine casualties occurred in Korean waters, during 1989-1993, were analysed by the Multivariate Data Analysis Method. The main results obtained were as follows : 1. Moat of marine casualties resulted from the human factors such as careless operation and insufficient engine maintenance. Engine trouble accounted for main patten of accidents and great number of accidents occurred in fishing vessels. 2. From the point of view of the damage of human life and properties, accidents took place in cargo ships, passenger ships and tankers were serious, but in fishing vessels, those were not so serious. 3. Grounding, collision mainly resulted from careless operation, however flooding and capsizing were much affected by bad weather and material defect.

Recently entered into an aging socity as the number of elderly drivers is increasing. Traffic accidents of elderly drivers are caused by driver inattentions such as poor vehicle control due to aging, visual information retrieval problems caused by presbyopia, and objects identifying problems caused by low contrast sensitivity. In this paper, detection method of ROIs on the road is proposed. The proposed method creates the saliency map to detect the candidate ROIs from the input image. And, the input image is segmented to obtain the ROIs boundary. Finally, selective visual attention regions are detected according to the presence or absence of a segmented region with saliency pixels. Experimental results from a variety of outdoor environmental conditions, the proposed method presented a fast object detection and a high detection rate.

The accidents related to boilers are caused by defects with high risk which can lead to the explosion of the equipment. The number of boiler accidents from 1979 to 2006 is 100 andthe casualties totaled 379, and the scale of accidents has been growing larger every year. The analysis has found that the number of accidents caused by carelessness in management is 59, 72% of total 82 cases and 18by low level of water. The analysis of accidents in foreign countries showed a similar result. From the past till today most of the accidents have been resulted from bad handlingand maintenance. The analysis of accidents for the inspected boilers also showed that the major cause of the accidents was bad handling and maintenance of automatic controllers, safety devices, etc. And in the large-scale explosive accidents, the number one cause of them was the low level of water.

Bluetooth utilizes a symmetric key that is exchanged at the first pairing to establish a secure channel. There are four authentication modes which enables device authentication, Just work, Passkey Entry, Out of Band, and Numeric Comparison. Up to now, Just work has been considered as the authentication mode that is vulnerable to Man-In-The-Middle (MITM) Attack. In addition, it is possible to intentionally change any authentication mode to Just work mode, in order to succeed in MITM Attack under Just work mode. However, this kind of attacks have just worked under the assumption that users should not notice that authentication mode was changed. In this paper, We analyze the specification of Secure Simple Pairing, LE Legacy Pairing and LE Secure Connection Pairing. When using Passkey Entry mode on each approach, it seems the MITM attack is possible. Also it offers Passkey Entry MITM attack that does not require assumptions about the user's fault, because it isn't change verification process of the authentication mode unlike traditional attacks. We implement the proposed MITM attacks. Also we presents a scenario in which an attack can be exploited and a countermeasure.

유사배(劉師培)는 '반청(反淸)'에서 반전통의 '무정부주의'로, 그리고 '친청(親淸)'으로 변절하는 파란만장한 삶을 살았다. "중국민약정의(中國民約精義)"는 유사배(劉師培)가 무정부운동을 하기 전, 즉 1903년에 완성한 저서다. 1903년은 유사배(劉師培)가 고향을 떠나 상해(上海)에서 반만(反滿) 운동을 시작했던 시기이고, 1907년 일본으로 유학가기 전 4년 여 동안 유사배(劉師培)는 반청(反淸) 운동에 적극적이었다. 따라서 "중국민약정의(中國民約精義)"는 무정부주의자들의 이념인 '반전통(反傳統)'의 관점에서 저술된 것이 아님을 알 수 있다. "중국민약정의(中國民約精義)" 서문은 다음과 같은 중요한 의미를 내포하고 있다. 첫째, 유사배(劉師培)가 참조한 루소의 "민약론"은 양정동(楊廷棟)이 일본어판을 보고 중국어로 번역한 "민약론"이다. 둘째, "민약론"의 내용은 널리 알려지지 않았다. 셋째, 원고는 1903년 이전에 완성되었고, 책은 1904년에 출판되었다. 유사배(劉師培)는 "주역"을 통해서는 '군민(君民)의 일체(一體)'를, "상서"를 통해서는 '군민(君民)이 국가의 공동주인'임을 밝혔다. "시"는 '민의(民意)의 표현'이라고 했으며, "춘추"를 통해 군주세습제와 민권(民權) 그리고 민의(民意)에 의해 관료 등용 등을 주장했다. "논어"를 통해서는 군신(君臣)의 대등 관계와 군민의 일체를 다시 강조하고, "맹자"와 "순자"를 통해 군주가 신성불가침의 영역이 아니기 때문에 민의(民意)를 근거로 군주도 바꿀 수 있다고 했다. 유사배(劉師培)의 이러한 주장만 놓고 보면, 중국은 비록 전제군주체제에 있었지만, 사람들은(人民) 민주제도를 향유한 것 같다. 그러나 실제로는 이와는 정반대의 길을 걸었던 것이 중국이다. 문제는 유사배(劉師培)의 주장처럼 루소의 "민약론"에 버금가는 사상과 역사적 사실이 있었음에도 불구하고, 그것을 제도화된 적이 없다는 점이다. 유사배(劉師培)가 "중국민약정의(中國民約精義)"에서 서술한 '민약(民約)'은 치도(治道) 방면과 비슷하다. 그러나 정도(政道) 방면에 대해서는 거의 언급이 없다. 게다가 서술된 '민약'의 내용이 한 번도 제도화된 적이 없다는 점에 대해 아무런 언급이 없다. 결국 비록 "중국민약정의(中國民約精義)"가 중국 전통사상에서 서구의 '민주' 개념을 모색했다는 점에서 높이 평가할 수 있으나, 그것을 제도화하지 못하고 또 치도(治道)에만 치중해 서술한 점이 "중국민약정의(中國民約精義)"의 약점이다.

In order to seize quantitative materials as part of studies on measures for oil pollution prevention and control, the statistics of oil pollution incidents in Korean coastal waters for 10 years from 2003 to 2012 were analyzed with relation to the number of oil spills and the volume of oil spilt according to causes, sources and sea areas of spills. Total number and total volume of oil spills for 10 years were found to be 2,833 cases and 17,877 kL, respectively. 50.4 %(1,429 cases) of total number of oil spills were caused by negligence, although oil spillage due to negligence was 294 kL(1.7 %). While oil spillage caused by marine accidents was 17,400 kL(97.3 %), marine accidents accounted for 27.9 %(790 cases) of total number of oil spills. While negligence had a great influence on the number of oil spills, marine accidents had a huge impact on the amount of oil spilt. Fishing boats accounted for 42.7 %(1,210 cases) of the number of oil spills, and although oil tankers accounted for 9.2 %(261 cases) of the number of oil spills, oil spillage from oil tankers was 15,488kL(86.7 %). It means that oil tankers such as VLCC or ULCC may be the main sources of major oil spills and a few very large spills are responsible for a high percentage of the amount of oil spilt. While the number of oil spill incidents was closely related to the accidents of fishing boats, the volume of oil spilt was greatly affected by the major oil spill incidents of oil tankers such as M/T Hebei Spirit. The number and volume of oil spills were shown to be 1,613 cases(56.9 %) and 3,804 kL(21.3 %) in South Sea, 700 cases(24.7 %) and 13,501 kL(75.5 %) in West Sea, and 520 cases(18.2 %) and 572 kL(3.2 %) in East Sea of Korea, respectively. The highest number of oil spills was found in South Sea and the most volume of oil spilt was shown in West Sea of Korea for 10 years.

현재의 의료 영역은 고도로 전문화되어 있고 더불어 의료의 분업화도 활발히 이뤄지고 있다. 의료의 분업화 과정에는 특히 서로 상이한 전문을 가진 의사들 간의 신뢰와 불신의 문제가 제기되는데 이러한 분업적 의료는 일반적으로 수직적 분업과 수평적 분업으로 구분할 수 있다. 수평적 분업의료에서는 원칙적으로 다른 의사의 주의깊은 행위에 대한 신뢰가 허용된다. 물론 그렇다고 하여 의사에게 검사 내지 재검사의 의무가 없는 것은 아니고 이를 필요로 하는 상황에서는 반드시 재검사가 이뤄져야 한다. 신뢰는 현행법의 과책원칙을 나타내는 '행위에 대한 자유'의 표현이며 의사에게 부주의한 행위가 있는 경우에는 신뢰가 인정될 여지가 없기 때문이다. 결국 재검사를 하여야 할 사정이 존재하지 않는 때에는 다른 영역으로부터의 보고를 원칙적으로 신뢰할 수 있다. 이처럼 본 연구에서는 지속적으로 전문화 및 분업화가 이뤄지고 있는 의료영역에서의 신뢰와 불신에 대한 개관을 통해 이를 재검토하고자 하였다.
