Many organizations apply reactive safety management to prevent the same or similar types of accidents by through investigation and analysis of the accident cases. Although research on investigation techniques has contributed a lot to the objective results of safety accidents and the preparation of countermeasures, many accident investigation techniques currently in use treat accidents from a linear perspective, revealing limitations in reflecting current systems dominated by complexity and uncertainty. In order to overcome these limitations, this study will review recent studies and concepts from a system safety perspective and predict future research trends through a case analysis of aviation accident. The models used in the analysis are STAMP, HFACS, and FRAM, and the characteristics of each technique are presented so that analysts who perform related tasks in the field can refer to them.

기존 신호등은 보행자를 위한 별도의 안전장치가 없다. 이는 어린아이는 물론 성인들까지 차량의 위협으로부터 안전을 보장받을 수 없다. 본 연구에서는 어린이보호구역에서 사고 발생률을 감소시키는 것을 전제로 아두이노 액추에이터와 스위치를 이용한 전자제어 신호등을 적용하고자 한다. 현재의 신호등 시스템은 단순히 시간의 흐름에 따라 보행자 신호등과 차량용 신호등의 led가 자동으로 변화하여 차량과 보행자를 통제한다. 이러한 시스템은 어린아이들의 돌발행동과 운전자의 미숙한 작동으로 인한 사고를 방지하지 못한다. 본 논문은 이러한 문제점들을 개선하기 위해 기존의 신호등 시스템 대신 스위치와 액추에이터, 초음파 센서, 블루투스 모듈을 적용한 어린이용 보호 전자제어 신호등 기술을 제안한다. 기존의 신호등 시스템과는 다르게 보행자의 직접적인 개입을 통해 시스템을 제어하고, 원활한 교통환경을 만들 수 있다.

최근 전체 교통사고 보행 사상자 중 우회전 차량에 의한 보행 사상자의 비율이 2018년 9.6%, 2019년 10%, 2020년 10.4%로 증가세에 있다. 현재는 이러한 상황을 해결하기 위해 국토교통부에서는 2022년부터 보행자 보호 의무 위반 운전자에게 최대 10%의 보험료 할증을 부과하고, 경찰청은 '교차로서 일단정지'를 골자로 하는 도로교통법 개정안을 공포하고 2022년 7월 12일부터 시행한다고 밝혔다. 본 논문은 이러한 상황에서 운전자나 보행자 모두가 안심할 수 있도록 하는 '보행자 안전을 위한 횡단보도의 구현' 기술을 제안한다. 법체계가 아닌 바리케이드와 초음파 거리센서, 압력센서 등을 활용한 물리적인 시스템으로 운전자들의 혼란을 해소하고 보행자들이 안심하고 건널 수 있는 횡단보도를 구현하여 최근 증가하고 있는 우회전 보행자 사고를 예방 할 것이다.

현대사회의 산업 현장에서 작업효율과 안전사고예방은 기업의 이익과 직결된다. 현장에서의 인력의 사용으로 인한 한계점을 가지고 있기 때문에 효율적이고 안정적으로 작업 효율을 내며 현장의 많은 안전사고를 미연에 방지하기 위해 많은 산업현장들은 4차 산업 혁명을 통해 수많은 작업들을 로봇을 이용한 자동화로 대체해 오고 있다. 단순히 짐을 옮기고 재고를 파악할 뿐인 간단한 작업임에도 불구하고 물류 피킹/분류 작업은 아직까지 인력을 사용한다. 인력을 한계를 극복하기 위해 작업 현장을 라인 트레이서를 통해 이동하고, 영상분석을 이용해 로봇 암으로 원하는 물건을 정확하게 피킹하고자 적재 하도록 설계한 '영상분석을 이용한 자동 피킹.분류시스템' 기술을 제안한다. 기존의 단순 반복 노동의 피킹/분류 작업을 수행하며 영상분석을 통해 어플리케이션을 이용하여 재고 관리또한 가능하다,

The importance of the security management system for the aviation infrastructure cannot be overemphasized. What is especially important on the security management system for it is the assessment that is detaild and systematic. This article presents a framework based on a Hanulcha-type security management system model for a Information security of the Aviation infrastructure. This system checks, estimates and analyzes the goal of security with effect, especially in case of the security-accident on the aviation infrastructure because this system model gives the integrated security assessment method.

In an effort to decrease aviation accident worldwide, development of aviation safety management has been sought through aviation index and standardization, both by establishing SMS(Safety Management System). It also needs to be done in the domestic. both study on SMS which ICAO recommends and setting the top priority safety goal, each differently classified by nations. Accordingly, defining safety index and developing continuous monitoring approach. Aircraft accident reporting system in Air Force does not operate in a open approach method due to its uniqueness related to mission achievement. Therefore, limits of utilizing the recent worldwide aircraft data sharing and analyzing results to prevent accident is inevitable. This paper introduces an overview of ECCAIRS 5 which become the standard for the recent worldwide aviation safety reporting and data exchange system. Also using ECCAIRS 5, aircraft accident cases of the Air Force are classified such as accident type, year, month, occurrence category, and flight phase. The result of the study will provide a guide line for utilizing the civil system in prevention of future military aviation accidents.

The purpose of this study is leading to prevent the major causes of commercial-aviation fatalities about controlled-flight-into-terrain(CFIT) in approach-and-landing accidents. The paper of major analysis for controlled flight into terrain(CFIT) was Guam accident, Mokpo accident and Gimhae accident in commercial transport-aircraft accidents from 1993 through 2002. CFIT occurs when an airworthy aircraft under the control of the flight crew is flown unintentionally into terrain, obstacles or water, usually with no prior awareness by the crew. This type of accident can occur during most phases of flight, but CFIT is more common during the approach-and-landing phase. Ninety-five percent of the Guam accident, Mokpo accident, and Gimhae accident where weather was known involved IMC, fog, and rain. The paper believed that prevention for CFIT accident was education and training for flying crew and upgrade for equipment such as EGPWS, and need more research for professional organizations of airlines, and accomplishing precision approaches should be a high priority.

The research purpose for The Impact of Aviation Safety over the Consumer's Behavior in Korea lies at the judgement that airline consumers' selection criteria has much changed after several serious aviation accidents as before when we used to overlook "aviation safety" variable through surveying to Korean aviation consumers and foreigners visit or travel Korea on various purposes. Therefore, for this research, practical analysis methods are employed after surveying to actual passengers who use Kimpo International Airport's international and domestic terminals. This study will be regarded significant in terms that empirical analysis was used to prove "Aviation Safety", a variable which had not been regarded as a airline choice factor within Korea air transport market so far, and has an effect on the aviation consumers' airline preference change and choice after recent frequent aviation accidents. Presenting this dissertation, I wish. it can be another opportunity for Korean two national flag airlines to reappraise and reinforce the significance of "aviation safety" and set forth immediate vigorous efforts to support the government's aviation safety improvement countermeasures. I hope the study to contribute and provide a variable idea and direction to improve aviation safety management of two Korean flag carriers.
