고령화가 급격한 속도로 진행되며 발생하는 문제 중 고령 운전자 사고는 해결되어야 하는 중요한 사회문제이며 사고를 감소하고자 하는 노력은 앞으로 맞이할 초고령 사회를 대비하기 위해 꼭 필요하다. 현재 고령자는 65세 이상으로 규정되어 있으며 이에 따라 고령 운전자 사고에 관련된 다양한 연구들은 65세를 기준으로 일반운전자와 고령 운전자를 구분하여 분석한다. 이러한 배경으로 인해 수용 가능한 정확도의 수준에서 실질적으로 교통약자로 분류되어야 하는 신체 능력을 갖춘 고령 운전자를 구분하는 기준은 제시되고 있지 않다. 따라서 본 연구에서는 상관분석을 이용하여 고령 운전자의 연령별 사고특성을 분석하여 연령군집별 사고 위험성을 비교하도록 한다. 분석결과 차종별 주요 사고특성에 대해 75세 이상의 경우 사고 발생에 미치는 영향력이 높아지는 것으로 나타났으며, 70세에서 80세 사이 구간에서 사고 발생 빈도가 상대적으로 낮았던 승용차에 대해서도 주요사고특성을 분석한 결과 75세 이상 84세 이하 구간에서 사고 발생에 대한 영향력이 높아지는 것이 두드러지게 나타났다. 이는 고령화가 진행되고 평균 수명이 늘어남으로써 고령자 구간 폭도 증가하는바, 고령자 내에서도 특성이 나뉘게 되며 본 연구를 통해 연령군집별로 사고 발생에 대한 영향력이 달라지는 것을 확인하였다.

As the construction project gets bigger in scale, the actual construction itself is becoming more complex. The construction accidents occupy 26.18 percent of total death disaster according to the accidents report in 2007. It is the highest figure among the entire industry, and it shows how serious the construction accident is. In order to reduce accidents occurred in the construction industry, we should find the accident characteristics of construction workers by age. In this study, we investigated 589 cases of fatal accidents, and classified them by trades, type of works, the things that caused the accident, how they occurred, and size. We then identified accident characteristics for each group by analysing them in accordance with workers age. The result of analysis showed that in carpenter and common laborer, the number of death accidents increased as the workers age increased. Another characteristics were that the number of death accidents increased as the age increased in finishing work and reinforced concrete construction and in a smaller-scale businesses, respectively. Common labor was the trade with the highest number of death accidents and the laborers of 50 age or higher in age in finishing working type were the most vulnerable to death accidents.

The nation is turning into aging society, and safety accidents among elderly people are on the rise. When death roll caused by safety accidents was investigated, senior citizens who died from safety accidents outnumbered the other age groups who died for the same reason. The most common cause of death was traffic accidents, followed by suicide and a hurt from a fall, and Korea rated first among OECD member nations in death roll by traffic accidents. Aging brings a lot of physical changes to elderly people, and they are often likely to be involved in accidents such as a hurt from a fall due to degenerated sensory organs like hearing and eyesight and deteriorated motor skills. Unsafe social facilities also have them face a lot of accidents, including fracture and death, and such accidents take place even at home that is usually considered safe, or are triggered by things of daily use. As a result of comparing every age group's death roll by safety accidents, the number of senior citizens who died from safety accidents was far higher than that of the other age groups who died for the same reason in every accident field. In aging society, a sharp increase in the elderly population and ensuing safety accidents are expected to pose a serious threat to national economy, and diverse efforts should be put into tacking this problem. For instance, safety education should be provided to people in general including senior citizens on a regular basis, and more safety facilities should be prepared. Besides, safety equipment should be developed.

Studies on the calculation of accident costs include the approach on calculating damage costs covering all accidents regardless of first or secondary party and the one calculating damage costs generated by a single victim. These two approaches have a limitation of considering a subject for costs analysis as a single entity. In addition, research on estimating the interaction effects caused in the relationship between diverse traffic accident features and factors remains inadequate since most studies focused on calculating costs incurred in a single entity such as a victim, damaged building, or social organization in charge of managing car accident. This study intends to identify the expected range of old age where a specific interaction effect would remain, compare accidents between old age section and the entire age section, and discover an exogenous variable to be applied in accident drop effects in senior people and reduced benefits by calculating and testing additional accident costs in case the first party and the second party all pertain to the senior age section. By classifying the entire accidents caused by old drivers according to the types of cars, significant coefficients representing the influence that affects car accidents according to the characteristics are calculated and set them as the representative variables by selecting top variable in accordance with from low to high order. Furthermore, characteristics on five age groups such as a group of over 65 and less than 70, a group of over 70 and less than 75, a group of over 75 and less than 80, a group of over 80 and less than 85, and a group of over 85 are elicited and compared them with these preselected accident characteristics variables, thereby identifying what changing effects come out.

Background: The clinical characteristics of pediatric nasal fractures can vary depending on the child's age, social activities, and environment. Therefore, this study aimed to analyze these characteristics in different age groups. Methods: We retrospectively reviewed of a series of patients aged under 12 years who received treatment between 2013 and 2021. The initial study design involved dividing the patients into four age groups, corresponding to different developmental ages, but there were no cases in infants aged 0 to 1 year. Therefore, the patients were divided into three groups: group I, between 2 and 5; group II, between 6 and 9; and group III, between 10 and 12 years of age. The following parameters were evaluated: sex, age, etiology, fracture type and severity, and the incidence of septal injuries. Results: In total, 98 patients were included in this study. In group III, the ratio of boys to girls was 3.88:1, exceeding the overall ratio of 1.97:1. The most common cause varied with age: slipping down in group I, bumping accidents in group II, and sports accidents in group III. Concomitant septal injuries were present in 4.17% of patients in group I, 5.71% of patients in group II, and 28.21% of patients in group III. Conclusion: Increasing age was accompanied by a greater tendency for male predominance and a higher prevalence of sports-related causes and septal injuries. Violence was infrequent but started to become a contributing factor during school age. These varying environmental factors across age groups can offer valuable insights into the epidemiology and clinical characteristics of pediatric nasal bone fractures.
