  • In April 2010, Japan Cabinet Office has published the first countermeasure report for severe flood disasters. This report showed various flood-disaster scenarios and factors that widened damages. One of important suggestions was to transmit precious information for long-distance evacuation. So far, local municipalities have made Flood Hazard Map to inform resident risk and evacuation. In this paper, cognition and effectiveness of a flood hazard map in the down ARAKAWA river Tokyo were measured by social questionnaire survey. In conclusion, there were 3 factors to effect validity of a flood hazard map. There were (1) commitment to their neighborhood organization, (2) experience of Kathleen typhoon in 1947 and (3) level of using targeted river. As results, a logical diagram about a flood hazard map perception was drawn and discussed from a view of community-based approach.

  • The hazard assessment in which the potential hazard factors In the buildings are investigated and the scale of the hazard is analyzed should be performed first in order to prevent personal and material damages due to building fire. In this study, the building fire hazard are assessed using 822-item checklist, for the qualitative evaluation of which the main factors are classified into 10 items, yielding 100 scale points with some weighting. It is shown that present model is applicable for the assessment of all general buildings through the examination of the suitability of assessment model by actual assessment of existing building. Also, the checklist is prepared in itemized questionnaire form for easy assessment of building fire hazard. Therefore, the present model will be helpful for those working in fire prevention, who are suffering from the lack of manifest evaluation model for the fire prevention assessment so far in Korea.

  • Purpose: To assess independent prognostic factors for lymph node-negative metastatic gastric cancer patients following curative resection is valuable for more effective follow-up strategies. Materials and Methods: Among 1,874 gastric cancer patients who received curative resection, 967 patients were lymph node-negative. Independent prognostic factors for overall survival in lymph node-negative gastric cancer patients grouped by tumor invasion depth (early gastric cancer versus advanced gastric cancer) were explored with univariate and multivariate analyses. Results: There was a significant difference in the distribution of recurrence pattern between lymph node-negative and lymph nodepositive group. In the lymph node-negative group, the recurrence pattern differed by the depth of tumor invasion. In univariate analysis for overall survival of the early gastric cancer group, age, macroscopic appearance, histologic type, venous invasion, lymphatic invasion, and carcinoembryonic antigen level were significant prognostic factors. Multivariate analysis for these factors showed that venous invasion (hazard ratio, 6.695), age (${\geq}59$, hazard ratio, 2.882), and carcinoembryonic antigen level (${\geq}5$ ng/dl, hazard ratio, 3.938) were significant prognostic factors. Multivariate analysis of advanced gastric cancer group showed that depth of tumor invasion (T2 versus T3, hazard ratio, 2.809), and age (hazard ratio, 2.319) were prognostic factors on overall survival. Conclusions: Based on our results, independent prognostic factors such as venous permeation, carcinoembryonic antigen level, and age, depth of tumor invasion on overall survival were different between early gastric cancer and advanced gastric cancer group in lymph node-negative gastric cancer patients. Therefore, we are confident that our results will contribute to planning follow-up strategies.

  • Efforts to identify jobs or tasks having known risk factors for work-related musculoskeletal disorder can provide the groundwork for changes aimed at risk reduction. An effective identification method is the ergonomic job hazard analysis which breaks a job into its various elements or actions, describes them, measures and quantifies the ergonomics risk factors. Some analytical methods including OWAS, RULA, REBA, and NLE have been used as tools in quantifying the risk factors. But these traditional methods using worksheet or paper are difficult to explain to participants for performing the job hazard analysis in the field, and take a long time. We develop some software tools to implement the analytical methods using EXCEL programs or computer program. These tools developed in this study are faster and easier to perform the ergonomic job analysis than the traditional methods using worksheet.

  • 본 논문은 한국노동패널을 자료로, 위험도 모형 (hazard model)과 Cox 모형을 이용하여 실엽탈출확률 및 요인분석을 시도한 것이다. 실업탈출확률 분석의 결과, 수도권의 경우 실업률 수준 자체는 높지만 실업기간은 오히려 짧은 것으로 나타났다. 수도권과 비수도권 간의 분절성의 존재가 확인되었으며 경상도가 전라도 및 충청도에 비하여 실업탈출확률이 높게 나타나 경상도가 여타 지방과의 차이가 있다는 점도 확인되었다. 구체적으로는 수도권의 평균 실업기간이 9.29개월인 데 비하여 비수도권은 11.86개월로 수도권에서의 실업기간이 2.5개월(유의수준 0.001) 짧게 나타나 수도권에서의 실업탈출이 훨씬 수월함을 알 수 있었으며, 전라도 경상도 간의 차이를 보면, 평균 실업기간에서 전라도가 10.95개월 경상도가 6.96월로 4개월 정도로 전라도가 길게 유의하게 나타난다. 한편, 실업탈출에 영향을 주는 요인분석 결과를 보면, 대도시 이외의 지역, 비수도권 등 노동시장 취약지역에서는 여성일수록, 근속기간이 길수록, 임금근로자일수록, 제조업, 도소매업에 종사했던 근로자일수록 실업으로부터의 탈출확률이 낮아지고 있다. 위의 사실은 지역별 업종별 노동시장정책이 필요하며 특히 지역별 한계근로자에 대한 특성을 파악하여 새로운 직종이나 산업으로의 이동이 원활히 진행될 수 있도록 노동시장정책이 지역별로 보다 세밀히 수립 집행되어야 함을 시사한다.

  • In order to evaluate landslide susceptibility in Yanbian region, this study analyzed 7 factors related to landslide occurrence, such as soil, geology, land use, slope, slope aspect, fault and river by Analytic Hierarchy Process (AHP), and calculated the weights of these 7 hazard-induced factors, determined the internal weights and the relative weights between various factors. According to these weights, combining the Remote Sensing technology (RS) with Geographic Information System technology (GIS), the selected area was evaluated by using GIS raster data analysis function, then landslide susceptibility chart was mapped out. The comprehensive analysis of AHP and GIS showed that there has unstable area with the potential risk of sliding in the research area. The result of landslide susceptibility agrees well with the historical landslides, which proves the accuracy of adopted methods and hazard-induced factors.

  • Background: Gastric cancer is one of the most common causes of cancer deaths all over the world and the most important reason for its high rate of death is its belated diagnosis at advanced stages of the disease. Events occur in patients which are regarded not only as themselves factors affecting patients' survival but also which can be affected by other factors. This study was designed and implemented aiming to identify these events and to investigate factors affecting their occurrence. Materials and Methods: Data from 330 patients with gastric cancer undergoing surgery at the Iran Cancer Institute from 1995-1999 were analyzed. The survival time of these patients was determined after surgery and the effects of various factors including demographic, diagnostic and clinical as well as medical, and post-surgical varuiables on the occurrence of death hazard without relapse, hazard of relapse, and death hazard with a relapse were assessed. Results: The median survival time for these patients was 16.3 months and the 5-year survival rate was 21.6%. Based on the results of multi-state model, age and distant metastases affected relapse whereas disease stage, type and extent of surgery, lymph nodes metastases, and number of renewed treatments affected death hazard without relapse. Moreover, age, type and extent of surgery, number of renewed treatments, and liver metastases were identified as factors affecting death hazard in patients with relapse. Conclusions: Most cancer studies pay heed to factors which have effect on death occurrence, but some events occur which should be taken into consideration to better describe the natural process of the disease and provide researchers with more accurate data.

  • Through the survey on the current status of hazardous substances in laboratories, the research institute is designed to establish measures to improve the management of university laboratories and to create a safe laboratory. We intend to explore countermeasures by confirming and reviewing the recognition of the statutes in the "Guidelines for the Implementation of the Laboratory Pre-Hazard Factors Analysis" through the questionnaire. Although there are various parts to create a pleasant environment for a laboratory, the most important part is the role of a laboratory manager in the area where each and every one of the laboratory's directors is the "Act on the Establishment of a Safety Environment in a Laboratory", but if the laboratory is not to be accident-prone, the laboratory's responsibility is to be more secure. This research is intended to be funded by research to reasonably implement" Guidelines for the Implementation of the Laboratory Pre-Hazard Factors Analysis" before applying to universities and to protect field-based research activities and to reasonably reduce safety accident prevention and risk.

  • 지하저장탱크에서 누출된 유기화합물은 인근의 토양과 지하수를 오염시키고 있다. 지하저장탱크를 관리하기 위해서는 탱크로 인한 환경 위해가능성을 파악할 필요가 있다. 본 연구에서는 지하저장탱크의 상대적 위해성을 추정할 수 있는 예비평가체계를 구축하였다. 지하저장탱크에 대한 위해성 예비평가체계를 평가인자의 선정, 평가인자의 계층구조화, 평가인자별 가중치 설정, 위해가능성 총점수 산정, 위해성평가 등 다섯 단계로 구성하였다. 구축된 예비평가체계를 서울시 관악구 소재 주유소에 적용하였고, 지리정보시스템을 이용하여 평가한 결과, 사례지역의 주유소는 위해가능성에 따라 세가지로 분류되는데 상대적으로 위해성이 높은 7개소의 주유소가 파악되었다. 또한 민감도 분석을 통하여 가중치 변화에 영향을 받지 않고 위해성이 높게 나타나는 4개소의 주유소를 파악하였다. 본 평가체계는 계층구조와 쌍대비교에 의한 가중치설정기법을 도입하였으므로 사용자가 자신의 전문적인 경험에 따라 본 평가체계를 유연하게 적용할 수 있을 것이다. 하지만 앞으로 현장조사결과와 비교하여 평가체계를 검증하고 갱신하는 작업이 수행되어야 할 것이다.
