지하사고가 발생할 경우 신속하게 원인을 파악하고 인적, 물적 피해를 줄여야 한다. 지하사고조사위원회는 발생한 사고의 원인을 규명하고 이후 동일한 사고가 발생하지 않도록 대응방안을 마련하는 역할을 한다. 그러나 지하사고조사위원회 운영 기간이 최소 6개월에서 최대 9개월까지 활동할 수 있도록 법에 명시되어 있어 실질적으로 동시간대에 추진 중인 건설 사업에서 사고조사보고서를 인용하고 검토를 통해 자체사업에 반영하기에 어려워 보인다. 본 연구에서는 기존에 3개월이 소요되던 자료수집과 분석을 최대 1개월 이내로 단축시킬 수 있도록 현장에 출동하여 자료를 수집하고 디지털트윈으로 구현하고 제공함으로써 지하사고조사위원회가 의사결정을 신속하게 할 수 있는 기술개발 전략을 수립해보고자 했다. 연구결과 5개 기술개발 분야인 지상 데이터 수집·전송기술, 지상안전 데이터 생성기술, 디지털트윈 기반 지하안전 분석·가시화 기술, 디지털트윈 기반 지오앰뷸런스 구축·운영 기술, 디지털트윈 기반 지오앰뷸런스 표준화 및 법제도 연구를 도출할 수 있었다. 제시된 기술이 개발된다면 기존대비 신속한 의사결정을 통해 사고현장을 줄이는데 기여할 수 있을 것으로 보인다.

The purpose of this study was to determine how often toddlers and preschoolers in kindergartens have accidents and what factors affect the accident rate. The study population consisted of 150 children who were attending at nursery schools and 150 children who were attending at kindergartens. The data was collected from ten nursery schools and five kindergartens from five districts in Daegu. The questionnaires were distributed to teachers of participating nursery schools and kindergartens to be completed using nursing care records in the institutions and by interviewing children's parents about all of the accidents happened in a previous year. Data were collected during the period of August 1 through 31, 2002. The results of the study are as follow: 1. Among 300 children, 282 had 506 accidental injuries during the study period. 2. The month, the day and the time with the highest accident rate were April. Monday, and between 2 and 4 o'clock in the afternoon, respectively. 3. Locations where the injury took place most included nursery schools or kindergartens, around the homes of the children, and inside the home. 4. Most accidents were occurred due to lack of carefulness of the children, and the most prevalent forms of injury was abrasions. 5. Most frequently injured part of the body was legs of the children. 6. Most injuries were healed within three days and required first aid measures to disinfect the wound. Mostly, these were performed by family members at home. Some children go to the hospital to suture the open wound. Most frequent type of complication was scar formation and the cost of the treatment ranged from 9,000 to 30,000 won. 7. Children's age. sex, birth order. personality. type of family composition. type of residency. father's occupation, father's age, and mother's age were significantly related to the frequency of injury among children. Children who were in nursery schools and kindergartens need their assessment for accident involving condition according to seasons, time. place.

On 7 December 2007, the Hebei Spirit, a 260,000 dwt VLCC, anchored near Korea's Daesan Port, was collided with a passing crane-carrying barge Samsung1, which was under tow of two tugs Samsung T5 and Samho T3. In this study, the behaviour of Hebei Spirit at the time of the accident has been reproduced and analyzed by simulation. This study precedes the study for the investigation of any available countermeasures for Hebei Spirit to prevent the accident. The simulation has been done only for Hebei Spiri and the motion of Samsung barge is just given with recorded AIS data. Dynamic characteristics of Hebei Spirit have been modeled based on empirical data and her sea trial data. Effects of current, wave and wind are also estimateed using empirical formula. Considering uncertainty of environmental condition and control of Hebei Spirit, simulation has been done by varying engine control method and holding power coefficients of the anchor. Finally, based on simulations, the most plausible scenario on the state of anchor and engine control could cause real accidents.

Purpose: This study was attempted to provide the basic data in order to develop a supportive system for the family by investigation of the general and disability-related features of the industrial accident disabled and their family function. Method: Three hundred and forty six industrial accident disabled were randomly selected among those who resided in the Seoul, Incheon, and Gyeonggi areas, and who were confirmed as disabled according to its severity from the first to fourteenth grade from January, 1998 to December, 2000. The data were collected for one month from August 1 to August 31, 2001. Each study team consisted of two members out of 20 researchers and they interviewed the disabled individually by visiting their homes. Collected data were analyzed using frequency, percentages, t-test, ANOVA, and Correlation, etc. Results: The average score for family function was 102.60. The adaptability represented the highest score among the concepts dependent on the family function. The concepts were cohesion, adaptability and communication, which scored as 33.59, 35.38, 33.34, respectively. The family function was significantly different in education, marital status and subjective health status. In particular, the family function was excellent from the industrial accident disabled who had graduated from middle school, was married, and felt healthy. Depression and quality of life were other factors, which were also correlated significantly with the family function. The lower the degree of depression and the better the quality of life, the better the family function. Conclusion: The industrial accident disabled who had been in poor health or faced with difficulties in daily activities even after the therapy for the disability was completed. In particular, their family always had a great burden to care for the disabled and to take financial responsibility. Therefore, the rehabilitation program for the disabled should be family oriented.

Objectives: This study aimed to provide temporal Acute Exposure Guideline Levels (AEGL) for a hazardous substance as a pilot study. Methods: As one of the substances designated by the Korea Ministry of Environment as requiring preparations for potential accidents, formaldehyde was selected to estimate the AEGLs. The calculation was based on Haber's formula (Cn×t=k) using valid toxicity data (for humans/animals). A total of 96 points of AEGL levels were provided using an interval of five minutes over eight hours. Results: The AEGL-1 and 2 values were constant for the entire exposure duration at 0.9 ppm and 14 ppm, respectively. The values were obtained from clinical/animal tests, and the adaptation effect after a given exposure duration was also considered. AEGL-3 was based on animal toxicity data, and it was estimated from 127 ppm for the initial five minutes to 35 ppm for eight hours. Conclusions: More specific AEGL levels for formaldehyde could be obtained in this study using toxicity data with Haber's formula. Based on this methodology, it would be also possible to estimate AEGL levels that can be used at the scene of a chemical accident for other substances requiring preparation for potential accidents.

Since the unprecedented hydrogen fluoride leak accident in 2012, there has been growing demand for customized technical information for rapid response and chemical accident management agencies including the Ministry of Environment, the National Emergency Management Agency, and the National Police Agency need more information on chemicals and accident management. In this regard, this study aims to provide reliable technical data and guidelines to initial response agencies, similar to accident management technical reports of the US and Canada. In this study, we conducted a questionnaire survey and interviews on initial response agencies like fire stations, police stations, and local governments to identify new information items for appropriate initial response and improvements of current guidelines. We also collected and reviewed the Canada's TIPS, US EPA's hydrogen fluoride documents, domestic and foreign literature on applicability tests of control chemicals, and interview data, and then produced items to be listed in the technical guidelines. In addition, to establish database of on-site technical information, we carried out applicability tests for accident control data including ① emergency shut down devide, safety guard, shut down valve, ground connection, dyke, transfer pipe, scrubber, and sensor; ② literature and field survey on distribution type and transportation/storage characteristics (container identification, valve, ground connection, etc.); ③ classification and identification of storage/transportation facilities and emergency management methodslike leak prevention, chemicals control, and cutoff or bypass of rain drainage; ④ domestic/foreign analysis methods and environmental standards including portable detection methods, test standards, and exposure limits; and ⑤ comparison/evaluation of neutralization efficiency of control chemicals on toxic substances.
