  • Background: Agriculture ranks among the most dangerous trades worldwide. There is, however, still a lack of knowledge on nonfatal injuries in agriculture. The aim of this study was to describe the nature and occurrence of nonfatal injuries in farmers in two counties in central Norway. Methods: A questionnaire was sent to 7,004 farmers in Norway. We asked for information about the respondents and the farm, whether the farmer had had work-related injuries on the farm during the past 12 months, and details about the incidence and seriousness of the injury. Results: A total of 2,699 respondents gave a response rate of 42%. Of the respondents, 249 (9.2%) reported one or more work-related injuries. The most usual cause of injury involved an animal, and >75% of these happened inside the outbuilding. Among these, 17.5% had a consequence of sick leave or a more serious result. When all the accidents were analyzed by stepwise logistic regression, only the variables: works alone, has >3,500 stipulated working hours at the farm, and the type of production were statistical significant explanatory variables for having an injury. Conclusion: Incorporating safety aspects to a greater extend in the design and construction of outbuildings would make a substantial contribution to injury prevention in agriculture.

  • A traffic accident which happens in Expressway during dense fog is more likely to cause the sequential accidents and high death rate. So, the preventive measures shall be taken at dangerous areas to enhance the efficiency of roads and minimize the accidents and the resultant damages. So, it is necessary to find out the characteristics of freeway zone which has high risk of fog occurrence and to establish the comprehensive safety strategy on installation and operation of the safety equipment. In this study, I developed a fog forecasting model by using the freeway fog data. This model can be used as the fog forecasting model in dealing with fog problems when new road is planned. The model was developed by using a statistical analysis technique or the regression analysis, focusing on the variables such as geographical features and regional conditions, distances to water sources and the area of water source. I have segmented the models by classifying the area into inland area and coastal area. The distance to water source and area of the water source located around the freeway were found to be main factors causing fog.

  • Significant portion of the fire accident is caused by some troubles in electric circuits. To prevent the fire induced by those electric trouble, some indications of electric fire need to be suitably detected at the first stage of the fire development. With this background, the characteristics of soot yielding of electric cables have been investigated using a light extinction method. In this study, a light scattering method was compared with the light extinction method. A slot-type premixed-flame combustor was traversed to bum three types of electric cables by compulsion, then the mass decrease rate and the soot densities were measured. According to the experimental results, the light scattering method is preferred to the light extinction method when the soot yield ratio is relatively small. Thus the former method is more suitable to detect the occurrence of an electric fire in a power distributer box.

  • 교통사고 위험도 지수 산정 모델의 개발은 교통사고와 사상자수의 발생률을 줄이기 위한 대책으로 도로이용자 그룹, 도로와 가로망의 구역, 인구집단 등에 대한 교통위험도를 수식 또는 모델화를 통해 사전에 적용하여 효과를 극대화하고자 한다. 국외에서는 위험도평가모형을 통해 단일로 및 교차로에 개선방안 우선순위를 선정하는 방법으로 활용하고 있으며, 국내에서도 일부 사업에 적용되어 활용하고 있는 실정이다. 하지만 모형의 독자적인 개발보다는 국외의 모형을 국내 실정에 맞도록 일부 변형하여 활용하고 있어 그 정확성에 의문이 제기되고 있다. 따라서, 본 연구에서는 춘천시의 96개의 교차로를 대상으로 교통사고 발생 현황, 기하구조, 통제방식, 교통량, 회전교통량 등을 통해 교차로 평가요소를 추출하였으며, 추출된 평가 요소들의 상관분석을 통해 최종적인 변수를 도출하였다. 최종적으로 도출된 변수를 바탕으로 신호 구분, 차로수, 교차로형태의 세변수의 선형모형 분석을 통한 분산분석 기법을 이용하여 교차로 디자인 모형을 개발하였으며, 교차로의 계층분류, 판별변수 선정을 통해 신호교차로 위험도 모형, 비신호교차로 위험도 모형을 개발하였다.

  • Purpose: Although trauma is the most common cause of death under age 18, Korean national pediatric trauma data has lack of clinical data. This study is to prepare manpower resources, equipment, and make a correct policy decision on pediatric trauma victims Methods: The study enrolled 528 patients under age 16 with traumatic injury visited Wonju Severance Christian Hostpital Trauma Center, from February 12, 2015 to December 31, 2016. We analyzed the distribution of gender, age, place and time of the accident, injury mechanism, injury severity, and injured organ by medical record. Results: The major injury mechanisms were blunt injury in 485 (91.90%), penetrating injury in 27 (5.10%), burn in 13 (2.50%), near drowning in 2 (0.40%), and foreign body ingestion in 1 (0.20%). Ninety-seven (18.4%) patients were injured at home and 67 (12.7%) patients were injured at school. The overall mortality rate was 1.13% (n=6). 5 mortalities were related to automobile accident and one was fall down. Mean Injury Severity Score (ISS) was 4 (2, 8). No statistical significance was observed in the mean ISS between each age group. The peak time of accident occurrence was between 16 and 17 o'clock. The mean ISS was higher in blunt injury group than penetrating injury with statistical significance ($6.50{\pm}7.60$ vs. $3.00{\pm}8.10$; p<0.05). The most common injury site was upper extremity. Mean ISS was highest in thorax injury. However, mean ISS of thorax injury was higher with statistical significance only compared with face, neck and upper extremity injury. Conclusions: We reported our pediatric trauma patients data of our hospital level I trauma center, which is the only one level I trauma center of Gangwon Province. These data is useful to prevent and prepare for pediatric trauma.

  • 1970년대부터 시작된 우리나라의 경제개발계획은 성장위주의 급격한 산업화의 영향으로 각종교통수단의 안전은 물론 항공안전관리체계가 정착되지 않은 채 지속되어 2000년 초까지 발생된 항공기 사고에 의한 인적 물적 피해는 물론 사회적으로 막대한 비용을 부담 하고 있다. 특히, 발생된 항공기의 사고요인으로는 항공종사자의 인적요인에 의한 사고가 대부분으로 이를 사전 발견하고 예방할 수 있다면 항공기의 사고율은 대폭 감소시킬 수 있을 것이다. 따라서, 민간항공안전체계의 제도적인 개선대안을 도출하고자 항공안전관리체계를 3단계인 사전적인 예방체계, 사고발생시의 처리체계, 사고 후 수습체계로 구분하여 항공안전 체계의 개선을 위한 단계별 개선대안을 발굴 제시하였다. 발견된 항공안전의 위해 요인들로서는 관리기준과 규칙의 부재, 무관심과 준법정신의 결여 등이 주 요인들로서 이를 개선하기 위해서는 항공안전 체계의 제도적인 정착이 선행되어야 하고, 정부와 항공업계도 항공안전을 위한 위해요인들을 발굴하고 준법정신과 안전을 최우선시하는 마음의 자세가 모든 종사원들에게 확산되도록 유인책을 제공하여야 한다.

  • The Community Health Service considers the family as a service unit and places the emphasis of its service on the health problems and the nursing needs of the family rather than the individual. From the conceptual point of view that tile community health service is both health maintenance and health promotion of the family, the community health nurse should have a knowledge of the growth and development of the family and be responsible for the comprehensive support of normal family development. The community health nurse often is in a position to make a real contribution to normal family development. In order to investigate the relationship between the areas of nursing need and family development, the following objectives were established 1. To discover the general characteristics of the study population by the stage of family development. 2. To discover specific nursing needs in relation to the family developmental stage, and to determine the intensity of the nursing needs and the ability of the family to cope with these needs. 3. To discover overall family health nursing problems in relation to the family developmental stage and determine the intensity of the nursing need and the problem solving ability of family. Definitions : The family developmental stages as classified by Dually were used stage 1. Married couples(without children) stage 2. Childbearing Families (oldest child birth to 30 months of age) stage 3. Families with preschool children (oldest child 2½-to 6 years) stage 4. Families with schoolchildren (oldest child 6 to 13 years). stage 5. Families with teenagers (oldest child 13 to 20 years) stage 6. Families as launching centers (first child gone to last child′s leaving home). stage 7. Middle- aged parents (empty nest to retirement) stage 8. Aging family member (retirement to death of both spouses) The areas of nursing need were defined as those used in the study, "A Comprehensive Study about Health and Nursing Need and a Social Diagram of the Community", by tile Nursing research Institute and Center for population. and Family Planning, July 1974. The study population defiled and selected were 260 nuclear families ill two myron of Kang Hwa Island. Percent, mean value and F- test were utilized in tile statistical analysis of the study result. Findings : 1. General characteristics of the study population by tile family developmental stage ; 1)The study population was distributed by the family developmental stage as follows : stage 1 : 3 families stage 2 : 13 families stage 3 : 24 families stage 4 : 41 families stage 5 : 50 families stage 6 : 106 families stage 7 : 13 families stage 8 : 10 families 2) Most families had 4 or 5 members except for those in stage, 1, 7, and 8. 3) The parents′ present age was older in the higher developmental stage and their age at marriage was also younger in the higher developmental stages. 4) The educational level of parents was primarily less than elementary school irrespective of the developmental stage. 5) More than half of parents′ occupations were listed as laborers irrespective of the developmental stage, 6) More than half of the parents were atheists irrespective of the developmental stage. 7) The higher the developmental stage(from stage 2 to stage 6 ), the wider the distribution of children′s ages. 8) More than half of the families were of middle or lower socio-economic level. 2. Problems in specific areas of nursing need by family developmental stage, the intensity of nursing need and the problem solving ability of the family : 1) As a whole, many problems, irrespective of the developmental stage, occurred in tile areas of Housing and Sanitation, Eating Patterns, Housekeeping, Preventive Measures and Dental care. Problems occurring ill particular stages included the following ; stage 1 : Prevention of Accident stage 2 : Preventive Vaccination, Family Planning. stage 3 : Preventive Vaccination, Maternal Health, Family Planning, Health of Infant and Preschooler. stage 4, 5 : Preventive Vaccination, Family Planning, Health of School Children. stage 6 : Preventive Vaccination, Health of School Children. 2) The intensity of the nursing need in the area of Acute and Chronic Diseases was generally of moderate degree or above irrespective of the developmental stages except for stage 1. Other areas of need listed as moderate or above were found in the following stages: stage 1 : Maternal Health stage 3 . Horsing and Sanitation, Prevention of Accident. stage 4 . Housing and Sanitation. stage 5 : Housing and Sanitation, Diagnostic and Medical Care. stage 6 : Diagnostic and Medical care stage 7 : Diagnostic and Medical Care, Housekeeping. stage 8 : Housing and Sanitation, Prevention of Accident, Diagnostic and Medical Care, Dental Care, Eating Patterns, Housekeeping. 3) Areas of need with moderate problem solving ability or less were as follows : stage 1 : Diagnostic and Medical Care, Maternal Health. stage 2 : Prevention of Accident, Acute and Chronic Disease, Dental Care. stage 3 : Housing and Sanitation, Acute and Chronic Disease, Diagnostic and Medical Care, Preventive Measure, Dental Care, Maternal Health, Health of Infant and preschooler, Eating Patterns. stage 4 : Housing and Sanitation, Prevention of Accident, Diagnostic and Medical Care, Preventive Measure, Dental Care, Maternal Health, Health of New Born, Health of Infant and Preschooler, Health of school Children, Eating Patterns, Housekeeping. stage 5 . Housing and Sanitation, Prevention of Accident, Acute and Chronic Disease, Diagnostic and Medical Care, Preventive Measure, Dental Care, Preventive Vaccination, Maternal Health, Eating Patterns. stage 7, 8 : Housing and Sanitation, Prevention of Accident, Acute and Chronic Disease, Diagnostic and Medical Care, Preventive Measures, Dental Care, Preventive Vaccination, Eating Patterns , Housekeeping. Problem occurrence, the degree of nursing need and the degree of problem solving ability 1 nursing need areas for the family as a whole were as follows : 1) The higher the stages(except stage 1 ), the lower the rate of problem occurrence. 2) The higher the stage becomes, the lower the intensity of the nursing need becomes. 3) The higher the stages (except stages 7 and 8), the higher. the problem solving ability. Conclusions ; 1) When the nursing care plan for the family is drawn up, depending upon the stage of family development, higher priority should be give to nursing need areas ① at which problems were shown to occur ② where the nursing need is shown to be above moderate degree and ③ where the problem solving ability was shown to be of moderate degree. 2) The priority of the nursing service should be Placed ① not on those families in the high developmental stage but on those families in the low developmental stage ② and on those areas of need shown in stages 7 and 8 where the degree nursing need was high and the ability to cope low.

  • 본 국내 건설업 사업자수는 매년 증가하고 있으며 산업의 고도화, 건설공사의 고층화 대형화로 건설업 근로자의 재해 노출 위험이 커지고 있다. 특히 문화와 언어가 다른 외국인 근로자 수의 증가, 다수의 중장년층 근로자, 옥외생산, 고소작업, 중장비 작업 등의 건설업 특성으로 타 산업에 비해 재해자가 많고 중대재해 위험 또한 높은 실정이다. 건설업의 경우 정해진 기간 안에 이루어져야하는 노동집약적 산업이고, 야간작업 등의 특수한 작업환경이 많으며 적정 공사비 확보가 안될 경우 안전관리에 대한 투자 또한 소홀하여 건설재해 요인에 대한 관리가 취약할 수밖에 없다. 건설업이 타 산업에 비해 재해율 및 사망률이 높고, 위험/특수한 작업환경, 다양한 국적 및 중장년층 근로자가 많다는 특성을 보았을 때, 위험요인 탐색을 통한 선제적인 건설 업종 현장 안전관리는 필수적이다. 본 연구에서는 건설 업종별 체계적인 위험관리를 위한 통찰력(Insight) 확보를 위해 지난 10여 년간 발생한 약 8500여 건의 건설재해사례를 분석하고 업종별 위험요인을 도출하였다. 분석결과 사고 다발 업종과 분석변수인 발생형태, 작업내용, 기인물, 가해물 간의 상호연관성을 살펴본 결과 각 분석변수와 사고 다발 업종은 서로 상호연관성이 있는 것으로 나타났으며, 특히 작업내용의 경우 각 업종과의 상호연관성 크기가 가장 큰 것으로 나타났다. 특히 사고 다발 업종 중 철근코크리트공사업과 토공사업은 재해발생빈도가 높을 뿐만 아니라 발생형태, 작업내용, 기인물, 가해물 내 대부분의 위험요인 카테고리에서 위험성이 높은 업종으로 나타났다.

  • 돌발홍수는 강우유출수가 하천으로 모여드는 유역이 좁은 지역에 집중호우로 인해 유입되는 물의 양이 급증하여 나타난다. 돌발홍수는 유속이 빠르고 홍수를 대비할 수 있는 시간이 부족하므로 인명과 재산상의 피해를 발생시킨다. 본 연구에서는 돌발홍수를 예보를 위한 빅데이터 분석방법을 수행하였다. 연구 자료는 2009년에서 2012년까지 국민안전처 국가재난정보센터에 보고된 38건의 홍수 피해 자료와 지표수문모형(TOPLATS)에 의해 생성된 수문기상정보인 강우량, 토양수분 상태, 지표유출량이다. 돌발홍수 발생 선행 6시간의 강우량, 토양수분 상태, 지표유출량 데이터를 요인분석을 통해 토양수분 상태, 장기요인에 의한 강우량과 지표유출량, 단기요인에 의한 강우량과 지표유출량으로 축소하였다. 빅데이터 분석 방법으로는 유형분석인 의사결정나무, 랜덤포레스트, 나이브베이즈, 서포트벡터머신, 로지스틱 회귀모형을 사용하였다. 돌발홍수 사고발생 자료가 38건으로 한정되어 있기 때문에 예측성능 정확도 판단이 중요하다. 예측성능 정확도 평가방법으로 kappa계수, TP Rate, FP Rate, F-Measure를 이용하였다. 이 외에 돌발홍수 발생 선행 시점별 재현성 평가와 과거 4년간 돌발홍수 경보 횟수를 통해 최적 유형분석 방법을 제시하였다. 연구결과 로지스틱회귀모형과 랜덤포레스트가 돌발홍수 예보를 위한 예측 성능이 가장 좋았다. 사고발생 자료가 2009년부터 2012년까지 38건으로 한정되어 있어 분석을 위한 훈련자료와 검증자료 구축에 한계가 있었다. 장기간의 자료가 수집된다면 더욱 정확한 빅데이터 분석을 수행할 수 있다.
