The Republic of Korea has a more rapidly aging society than any other country in the world. In order to prepare for the attendant challenges, this research provides basic data for policies related to aging ship officers, analyzing the relationship between elderly ship officers and marine accidents. The data used here spans 11 years, from 2006 to 2016, and the survey and regression analysis were conducted only on ship officers, excluding crew. As a result of this research, first, it was found that the number of employed ship officers older than 60 has increased 2.7 times over the past 11 years and the range of this increase was larger than for other age categories. Second, the number of elderly ship officers disciplined for marine accidents increased by around 2.6 times. Third, elderly ship officers had around 1.5 times the rate of marine accidents compared to non-elderly ship officers. Fourth, as a result of conducting regression analysis between the number of employed elderly ship officers and the number of officers disciplined, the degree of explanatory power of elderly ship officers for disciplined officials was 75.1%. Since our society will age quickly, policies such as license renewal education for elderly ship officers and regulation enforcing the quality of renewal will be needed.

This study came to the following conclusions through the survey which was conducted to ocean leisure business runners to find out current business situation and the perceptions about the revised regulations the safety law of water leisure. This survey showed that most of the respondents agreed about receiving water safety training for regulated time when they obtain or renew their licenses. 63.5% answered that water safety training is needed. There was a considerable demand for registration system of leisure boots. 70.3% presented that registration system of private leisure boots should be introduced. It is confirmed that insurance is an essential fact for ocean leisure activities. 81.1% for leisure boots and 70.3% for non-leisure boots respectively answered that private insurance or fraternal insurance need to be imposed as a compulsory condition in case of accidents during ocean leisure activities.

The purpose of this study is to deduce improvement plan through analysis of the type and characteristics of traffic accidents caused by elderly drivers, and to establish the traffic safety policies for the elderly drivers. The analyzed result of road traffic accident situation are as follows. Firstly, Traffic accidents caused by elderly drivers were frequent on local roads of poor traffic safety facilities such as lighting. Secondly, The most frequent time zone of Traffic accidents caused by elderly drivers was 18:00 to 20:00, this time zone was mainly darkened. Thirdly, Traffic accidents are often caused by lack of attention occurred by no implementation of safe driving. Institutional Improvement of cosideration for elderly drivers and Traffic Safety Facilities maintenance considering regional particularities is needed for reducing traffic accidents and the safety of our society. Their driving skills of elderly drivers should test themselves constantly, and elderly drivers must hold down driving yourself using the alternative transportation.

The purpose of this study is to provide some basic information for elderly driving safety, by analyzing the current state. This study analyzed 128 survey questionnaires given to senior welfare center user in P city and evaluated Montreal Cognitive Assessment Korean Version(MoCA-K) and Neurobehavioral Cognitive Status Examination(NCSE) for checked 41 owner drivers by questionnaires. 32% of total elderly persons was owner driver, and 56.1% of elderly drivers was driving everyday. 56.1% of elderly persons was driving for 1-2hours per day. 46.3% of elderly persons was using a car for leisure activity and 31.7% of elderly drivers was experienced a car accident. As cognitive function evaluation, some elderly drivers showed scores lower than average in subcategories of cognitive functions for driving a car. So, methodical evaluation system for accurate evaluation of deficit ability and driving re-education system will be required for safety driving of elderly person. In future, a legal approach of government as driver licence management and renewal system will be required for safety driving of elderly person.

Alcohol, which can easily be obtained in the same way as ordinary beverages, is harmful enough to cause death due to excessive drinking and chronic alcohol intake, so it is important to maintain a proper amount of drinking and healthy drinking habits. In addition, the incidence of behavioral disturbances and impaired judgments that can be caused by chronic alcohol drinking of more than adequate amounts of alcohol is also significant. Accordingly it is very useful for forensic science to check whether the person involved is drunken or is alcoholism state in various accidents. Currently, in Korea, alcohol consumption is determined by detecting the level of alcohol or alcohol metabolism 'ethyl glucuronide (EtG)' in blood or urine samples. However, analysis of alcohol or EtG in blood or urine can only provide information about the current state of alcohol consumption because of a narrow window of detection time. Therefore, it is important to analyze the EtG as a long-term direct alcohol metabolite bio-marker in human hair and to investigate relationship between alcohol consumption and EtG concentration for the evaluation of chronic ethanol consumption. In this study, we established an analytical method for the detection of EtG in Korean hair efficiently and validated selectivity, linearity, limits of detection (LOD), limits of quantification (LOQ), matrix effect, recovery, process efficiency, accuracy and precision using liquid chromatography tandem mass spectrometry (LC-MS/MS). In addition, the assay performance was evaluated in Korean social drinker's hair and the postmortem hair of a chronic alcoholism. The results of this study can be useful in monitoring the alcohol abuse of Korean in clinical cases and legal procedures related to custody and provide a useful tool to evaluate postmortem diagnosis of alcoholic ketoacidosis in forensics.
