As the number of automobile registrations increases yearly, parking spaces that are located in downtown areas are increasing, and mechanical parking facilities are also increasing. Therefore, there is a high risk of accidents when installing and repairing a mechanical parking facility. In the preceding six years (from 2012 to 2018), the statistics that pertain to accidental disasters indicated that a total of 137 disaster victims were generated by the construction sector, 33 accidents occurred, and 10 people died. However, only the safety management items pertaining to accidents that occur during maintenance work and the use of the installed mechanical parking facilities are being studied; furthermore, there is no ongoing research with respect to the risk management that is conducted at the construction site. In 2017, the Korea Occupational Safety and Health Agency (KOSHA) announced the "Guidelines for Safe Installation and Maintenance of Mechanical Parking Equipment"; however, it is a safety guideline that is limited to the installation of basic protective equipment and to facility installation. There is no model for mechanical parking facilities that is indicated in the "Risk Assessment Model by Construction Industry Type", which is issued by the Safety and Health Corporation and is widely utilized for risk assessment in the construction industry; moreover, elevator installation work CODE N0: 22 is the only major example of a disaster. In this study, "risk assessment through a focus group interview" was performed, and data was derived from the "risk assessment of Article 41 (2) of the Industrial Safety and Health Act", which reflects the characteristics of the construction industry based on AHP analysis. The results of this study can be utilized for the risk assessment that is conducted during the construction stage of mechanical parking facilities.

연구목적: 본 연구는 기존의 보이스피싱과 신종 보이스피싱의 특성 및 진행과정을 비교·분석하여 심리적 기재를 기반으로 한 신종 보이스피싱에 대한 대응방안을 마련하는 정책적 기초 자료를 제시하는 데있다. 연구방법: 기존 보이스피싱에 대한 연구와 신종 보이스피싱 시나리오를 중심으로 한 각종 포털사이트에 있는 피해사례 등을 통해 양자의 범죄 진행과정 및 특성을 비교·분석하였다. 연구결과: 범죄준비 단계에서는 양자 모두 심리적 기재를 기반으로 하지만, 신종 보이스피싱은 피해자를 기망할 수 있는 시나리오가 더욱 치밀하게 작성되었고, 범행대상 범위가 확장되었다. 범죄실행단계에서는 신종 보이스피싱의 경우 피해자를 사회적으로 고립시켜 피해자의 판단능력을 저하시키고, 수사기관의 수사를 더욱 어렵게 하였다. 마지막단계에서는 금품 갈취 등 범죄피해의 지속성과 확장 가능성이 나타났다. 결론: 보이스피싱을 비교·분석하여 보았을 때 범행 대상 및 범위 그리고 범죄전략, 수법 등에 차이가 있었으며, 이에 따른 피해발생 가능성도 훨씬 크기 때문에 보다 더 효율적이 대응전략이 마련되어야 할 것이다.

Among natural disasters that lead to devastating damage, floods from heavy rains have been causing hundreds of victims and a great loss of their properties every year. Basically, there is no other way to deal with the problem considering it is a kind of natural disaster, but more specific studies for a preventive measure of flood has been in progress so far. However, the controversy over the problem is going on due to the objection of some environmental organizations or some economic reasons. The key important thing is select the most suitable area for a preventive measure of flood where a huge amount of national budget is put into, which is also the factor to judge it would be success or failure, therefore, in this study, it is made to be profitable to decide the priority order in a plan for preventing disasters by drawing more accurate data conveniently from the connection with GIS when you get some information of configuration of the ground and using them into the economic analysis for flood prevention industries.

Last year, a disastrous accident happened on the sea. Car ferry Se-wol which was on its way from In-cheon to Je-ju sank in the middle of the western sea. 304 passengers were drowned at the sea in the accident. There were no passengers who were waiting on board ship rescued in the accident. This study is to review the pattern of decision making in the middle of saving a life, right after Se-wol was about to sink. The starting point of this study is decision making on the rescue by rescue corps with no expert knowledge at the initial stage. When it comes to saving victims, there was no expert on rescue on the sea. Failure in rescue at Se-wol disaster lets us find a vicious circle of positive feedback loop. Experts with no experience act like well-qualified persons. Unqualified persons(leaders) have no expertise. Those who pretend to be expert occupy the important post in the hierarchy. It means we could not accumulate expertise of know-how in rescue division. That's why a vicious circle of positive feedback is formed in areas of disasters. It is necessary to train experts in Government Organizations to weaken the vicious circle of positive feedback.

지하철 역사 화재는 다수의 인명피해를 동반한 대구 지하철사고 이후 지하철 차량 내장재, 지하역사의 제연 시스템과 승객이 지상으로 탈출하기 위해 필요한 피난시간 등과 같은 기존 시스템에 대한 적정성 논란을 가져왔다. 기존의 제연설비는 화재 시배기 용량과 역사 시설구조의 복잡성으로 인한 제어방법의 한계가 따른다. 특히 지하철 역사 화재는 지중에서 지상으로 대피하는 형태로서 이는 부력으로 인한 연기의 이동방향과 피난방향이 같아지게 되므로 피난자들이 일반화재보다도 더욱 많은 연기의 영향에 노출되어져 버리는 결과가 발생한다. 본 연구에서는 하향식 피난 동선을 설계하여 피난완료시간의 단축 및 연기 층으로부터 피난자들을 격리시켜 희생자를 줄일 수 있는 방안을 제안하였다.

During five years (Year 2009~2013), Total victims of 72 %(81,560 people) and those 50.6 %(1,258 people) of death accident occurs in small scale construction site which operate 2 million USD less construction budget. Especially, falling death accident account for 785 people, in the share of 33.2 %(261 people) death disaster takes due to defect of original cause materials. The major safety issues in small scale work place take place while scaffold installation, disassembling, work-plate improper installation or non-professional skills of workers. Furthermore, labor subcontract systems make small construction site shortage of resources. Those workers regard work-plate as unnecessary and consumables supplies. Because of that most of workers use unsafe workplace in most construction site. Therefore, in order to prevent falling accident occurring in small scale work site, government should organize related regulations such as "Work site safety construction method" and then expands education support, financial aid, and sourcing safety supplies for work plate which offer broad variety experiences. Also, introduce certificate solutions for various work plates to improve safety function such as anchoring type method and anti sliding function.

Purpose: The goals of this research are to find out factors influencing the duration of work-related disability and to present implications for policies to prevent delayed recovery. Method: The subjects of this study were 238 workers who had been proved to be industrial disaster victims for occupational low back pain between January 1 2000 and December 31 2003. Kaplan-Meier method was used to estimate the proportion of duration of disability associated with low back pain, and Cox proportional hazards analysis was used to identify factors predicting it. The model distinguished main symptom variables affecting acute(${\leq}90\;days$) and chronic phase of disability (>90 days). Result: Fifty percent of the workers had not recovered in 408 days. The results of Cox regression show that delayed duration of disability was predicted by diagnosis, pain radiation (in chronic phase), sex, the size and labor union of the workplace, scheduled rest, compensation from the company, and operation. Conclusion: Duration of disability associated with compensated low back pain is influenced not only by factors related to the company and compensation system but also by individual factors. Thus, future efforts to reduce duration of disability may need to take into account all these factors.

This study analyzed the safety management efficiency through input-oriented BCC Model using DEA by making of Models, in which this study selected the number of staff affiliated with the construction site, number of staff members on the construction team, and number of safety personnel as Input Factor, along with the number of disaster victims and zero-accident accomplished hours as output elements, targeting 40-or-so apartment building construction sites which are being built by 3 domestic construction companies. As a result of efficiency, it was 0.643, the number of efficient DMU was 4. In the aspect of returns to scale, 21 construction sites(52.5%) found to be in a state of increasing returns while 14 construction sites(35%) was in a state of Decreasing returns. The reason for inefficiency was found to lie in technical factors in case of 30 construction sites(75%). Lastly, inefficient DMU is in need of 38.9 % and 66% reduction in site personnel and safety personnel. Based on study results, the 29 construction sites accounting for 72.5% of DMU for safety management efficiency evaluation object turned out to do inefficient safety management that doesn't fit the size of each company.

Background: A contamination screening process for the local population in radiation emergencies is discussed. Materials and Methods: We present an overview of the relevant Korean governmental regulations that underpin the development of an effective response system. Moreover, case studies of foreign countries responding to mass casualties are presented, and indicate that responses should be able to handle a large demand for contamination screening of the local public as well as screening of the immediate victims of the incident. Results and Discussion: We propose operating procedures for an off-site contamination screening post operated by the local government for members of the public who have not been directly harmed in the accident. In order to devise screening categories, sorting strategies assessing contamination and exposure are discussed, as well as a psychological response system. Conclusion: This study will lead to the effective operation of contamination screening clinics if an accident occurs. Furthermore, the role of contamination screening clinics in the overall context of the radiation emergency treatment system should be clearly established.

Objectives : The aim of this study was to investigate Post Traumatic Stress Disorder (PTSD)-related symptom severity, level of functional impairment and personality profiles between full-blown PTSD, partial PTSD and non-PTSD groups among 59 adolescent survivals from the Incheon fire disaster. Method : Using Short Screening Scale for DSM-IV PTSD, victims of the disaster were assigned to a full-blown PTSD group (n=18), a partial PTSD (n=22), or a non-PTSD group (n=19). Assessments included the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), the Impact of Event Scales (IES), the McBride's Degree of General Labor Loss, and the Korean Version of Temperament and Character Inventory (K-TCI). Results : Significantly severe PTSD symptoms (F=4.832, df=2, p<.05) and functional impairment (F=12.144, df=2, p<.01) were demonstrated by PTSD groups as compared to the non-PTSD group. Interestingly, full and partial PTSD did not differ in these comparisons. Similarly, the subtypes of PTSD did not differ with respect to personality profiles using the K-TCI ; however, personality profiles were sharply differentiated between the PTSD and non-PTSD group. Conclusion : Although high subject homogeneity and small sample size may limit the results of this study, the present results highlight the possibility of the underestimation as well as the insufficient, treatment and compensation of partial vs full PTSD.
