This thesis suggests how to design and implement an Android smart phone application which can perform self check or safety inspection of lifts effectively. The safety checks of lifts go in the way that inspectors check the lifts' conditions generally and record manually following a form at the moment. This thesis analyses lift maintenance industry and introduces how to design a system to proceed effective self check using a smart phone with Android OS. By using a smart phone to check lifts, we can have advantages to improve the quality of self check and maintain careers establishing information database about safety items.

With the recent growing importance over safety management the need for advanced and technical approaches for on-site safety inspection methods has increased. Railway construction is subject to its own particular set of temporal and spatial challenges due to its unique facilities and equipment. This study aimed to investigate the field characteristics of railway infrastructure and improve the conventional field safety management methods by identifying the most appropriate features of AR technology. Group interviews and surveys were conducted with field safety experts to derive the major problems and inspection needs. Subsequently, various features of AR, such as BIM model projection, and remote conferencing, were investigated to determine their applicability to address safety issues. As a result, four problems in the current safety management process, such as 'lack of time due to the conventional inspection method and inspection of areas that are difficult to access', and three major inspection types, such as 'observance of work procedures, status of installation, adequate dimensional spacing', were identified to be improved when adopting AR based techniques. Furthermore, AR technology utilizing plans to solve safety inspection problems and effectively manage major inspection types were proposed, and a follow up survey was conducted with the same field safety experts to derive the priority of technology development.

안전관리 규정에 전기설비의 유지 및 운용에 관한 안전관리를 위한 순서 점검 및 시험을 별표에 정하는 기준에 따라 실시한 것이라고 규정되어 있으므로 본 절에서는 안전관리규정의 기준을 중심으로 하고 다시 안전확보를 위하여 바람직하다고 생각되는 약간의 보충사항을 더하여 정리하여 보았다.

월차점검 및 정기점검 등에서 점검, 시험의 결과, 지급수리 혹은 개수를 필요로 하는 곳을 발견하였을 때는 설치자에게 그 취지를 설명하고 개수를 설정함과 함께 대행의 경우 자가용전기설비에 관한 통보서 2통을 만들어 1통은 설치자에게 제출하고 1통은 설치자의 확인을 받아 전기안전관리사 등이 보관하고 불량개소 등의 개수, 개선에 노력하고 사고의 미연방ㅈ를 도모하는 것이 전기안전관리사 등의 중대한 임무의 하나로 생각하여 시기가늦어지지 않도록 실행하여야 한다

본 연구에서는 울진 3, 4호기 보조급수계통의 1/4 다중안전계통에 대해 기기불이용도식을 유도하여 점검주기 변화에 따른 기기 불이용도를 평가하였고 계통단계에서는 IRRAS Code를 사용하여 계통 불이용도를 평가하였다. 그리고 선형 열화 모델을 이용하여 잦은 점검으로 인한 역효과가 계통 및 기기 불이용도에 미치는 영향을 평가하였다. 상기 역효과를 고려하였을 경우 점검주기 변화에 따른 기기 및 계통의 불이용도는 거의 유사한 경향을 보였고 점검주기가 대략 2개월에서 기기 및 계통 불이용도가 낮게 나타났다.

According to "Special law for the safety management of facilities", facilities of group 1 and 2 which are larger than a specified size should be examined periodically by experts. In addition, the other ones not belonging to the group 1 and 2 should be also managed in accordance with "Basic law for the management of disaster and safety" by the facility managers. However, there are many cases that these regulations are not kept in the field of safety management because most of safety management work has been done manually without a formal procedure. The purpose of this research is to develop an facility safety management system based on the National Geographic Information System(NGIS) which can integrates and manages the facility safety management information. The final system integrates the information which is related to several laws and distributed among several organizations.

금융회사들은 자사와 제휴 또는 외부 주문하고 있는 사업자들에 대해 전자금융 침해사고 예방을 위한 안전성 점검을 개별적으로 실시하고 있다. 이러한 개별점검 방식은 금융회사와 제휴사업자 모두에게 인력 및 비용, 시간 면에서 비효율적이며 금융회사마다 점검기준이 서로 달라 제휴사업자 측면에서 대응하기가 어려운 상황이다. 따라서 본 논문에서는 금융회사와 제휴 또는 외부 주문하는 사업자들에 대한 개별점검방식의 문제점을 보완할 수 있는 합동점검 프레임워크 구축 개발을 통해 합동점검의 효율성을 기술한다.

In general, the daily safety inspection activities, which investigate damages in structures and measures the size of the damage, have been relied heavily on the visual inspection so far. Since the probe of the condition and performance of facilities by such personnel is often dependent on the subjective judgment of the investigator, the consistency and repeatability of the probing results may reduce. Particularly, damage located in a difficult-to-reach place depends mainly on experience with the naked eye, and an unsafe method using a ladder has mainly applied when necessary. Therefore, in this study, we tried to propose a way of using images that can reduce the deviation between safety inspection investigators, enhance objectivity, and improve the safety of workers. In this study, we have applied homographic transformation as a method of correcting the image. As a result of analyzing the size of the damage in the corrected image of the test subject, it confirms that the accuracy of measuring the magnitude of the damage can satisfy the target levels of 5.0mm and 0.005m², the target accuracy levels. As a result of the field verification test to which the proposed image correction technique applied, the coefficient of variation of the crack length in the structure decreased from 5.4~7.0% to 0.072~0.12%, and that of the damaged area from 10.9% to 1.6%. It confirms that the measurement accuracy is improved. Therefore, it is expected that this study on the image utilization technique in safety inspection activities can increase the accuracy of damage measurement and improve the reliability of the safety inspection reports and exterior survey drawings.

As importance of the field of maintenance and management come to the fore because of collapses of the Seongsu bridge and the Sampoong department store, "Special Act for the Safety Control of Public Structures" was established in 1995 and the major maintenance and management system began taking effect "Detailed inspection and Precision safety diagnosis". However, a technical standard of "Detailed inspection and Precision safety diagnosis" was low because its history was not long, and also the results of research were not enough so anxiety for "Insufficient Detailed inspection and Precision safety diagnosis" was continuously left. While its evaluation system introduced in 2002, the ratio of "Insufficient Detailed inspection and Precision safety diagnosis" has been getting lower. However, according to the evaluation result after carrying out "Detailed inspection and Precision safety diagnosis" recently, it seems difficult to become lower for the ratio of "Insufficient Detailed inspection and Precision safety diagnosis" in future. Therefore, it is considered of questionary survey of the concerned organization and the mechanism side in connection with "Insufficient Detailed inspection and Precision safety diagnosis". So it is arranged the fundamental problems caused by an "Insufficient Detailed inspection and Precision safety diagnosis" that is to show the improving direction of the existing evaluation system in a based on this.
