National Health Insurance Act has been enforced all over the People as part of the effort to assure the minimum constitutional human worth and dignity in the aspect of the right to pursue health for preventing misfortune that comes to death without even a chance to be received treatment for illness or injury. Meanwhile auto insurance is compulsory in certain parts in order to promote benefits of everyday life and the rapid recovery of the damage caused by traffic accident when one have negligently driven a car which has become the necessities in daily life. Any injured driver in a traffic accident can be treated by National Health Insurance without getting an auto insurance in various circumstances, but Article 3 paragraph 2 of Traffic Accident Act don't allow exception of criminal punishment when he has driven a car without license, drunken, or tresspassing the centerline, etc. When the injury occured by his own certain negligence is judged to 'when he has intentionally or through gross negligence caused a criminal conduct or intentionally contributed to the occurrence of an accident' of National Health Insurance Act, insurance benefits can be restricted. Such a restriction could harm the right to pursue happiness and health of People by depriving the poor, who cannot afford to pay, of chances to get treatment. Here we will see benefit restriction by 'gross negligence' of National Health Insurance Act Article 48 paragraph 1, which has largest portion of such restriction. It is desirable to delete 'gross negligence' clause from above paragraph and to interpret 'when' clause restrictively for diminishing confusion of interpreting and guaranteeing the right of health.

Recently, IITS (intelligent integrated transportation system) has been important topic in Smart City related industry. As a main objective of IITS, prevention of traffic jam (due to car accidents) has been attempted with help of advanced sensor and communication technologies. Studies show that car accident has certain correlation with some factors including characteristics of location, weather, driver's behavior, and time of day. We concentrate our study on observing auto correlativity of car accidents in terms of time of day. In this paper, we performed the ARIMA tests including ADF (augmented Dickey-Fuller) to check the three factors determining auto-regressive, stationarity, and lag order. Summary on forecasting of hourly car crash counts is presented, we show that the traffic accident data obtained in Korea can be applied to ARIMA model and present a result that traffic accidents in Korea have property of being recurrent daily basis.

Advances in Internet of Things Technology lead to the increasing number of daily-life things that are interconnected over the Internet. Also, several smart services are being developed by utilizing the connected things. Among the daily-life things surrounding user, the mirror can supports broad range of functionality and expandable service as it plays various roles in daily-life. Recently, various smart mirrors have been launched in certain places where people with specific goals and interests meet. However, most mirrors give the user limited information. Therefore, we designed and implemented a smart mirror that can support customized service. The proposed smart mirror utilizes information provided by other existing internet services to give user dynamic information as real_time traffic information, news, schedule, weather, etc. It also supports recommendation service based on user usage information.

This paper examined the changes of urban system through the network and the flow pattern reflected in daily movement in Korea. Because daily movement reflects trip pattern, urban system formed by inter-city linkages can be recognized in terms of living sphere. While population movements between cities have the number of linkage systems of city network and the number of traffic regions composed of the origin and destination has increased respectively. Nevertheless, spatial extent of Capital region and Busan region has been expanded. In Gangwon-do in which Seoul-oriented high-speed transportation network has developed, separation of living sphere between Yeongdong area and the Soyanggang cultural region formed around Chuncheon was intensified. Living sphere that includes Daejeon and the surrounding cities has been expanded to the southern Gyeonggi-do. The existing living sphere formed in Jeollanam-do was fragmented into the east and west around Mokpo and Suncheon due to the weakened centrality of Gwangju. Living spheres formed by spatial interaction were consistent with regional administrative boundary. Considering the increased interaction between Seoul and its surrounding cities, the development of global city-region centered on Seoul is expected.

In the past 10 years, the accidents caused by drowsy driving have occupied about 23% of all traffic accidents in Korea expressway network and this rate is the highest one among all accident causes. Unlike other types of accidents caused by speeding and distraction to the road, the accidents by drowsy driving should be managed differently because the drowsiness might not be controlled by human's will. To reduce the number of accidents caused by drowsy driving, researchers previously focused on the spot based analysis. However, what we actually need is a segment (link) and occurring time based analysis, rather than spot based analysis. Hence, this research performs initial effort by adapting link concept in terms of drowsy driving on highway. First of all, we analyze the accidents caused by drowsy in historical accident data along with their road environments. Then, links associate with driving time are analyzed using digital tachograph (DTG) data. To carry this out, negative binomial regression models, which are broadly used in the field, including highway safety manual, are used to define the relationship between the number of traffic accidents on expressway and drivers' behavior derived from DTG. From the results, empirical Bayes (EB) and potential for safety improvement (PSI) analysis are performed for potential risk segments of accident caused by drowsy driving on the future. As the result of traffic accidents caused by drowsy driving, the number of the traffic accidents increases with increase in annual average daily traffic (AADT), the proportion of trucks, the amount of DTG data, the average proportion of speeding over 20km/h, the average proportion of deceleration, and the average proportion of sudden lane-changing.

AADT(Annual Average Daily Traffic) can be obtained by using short-term counted traffic data rather than using traffic data collected for 365 days. The process is a very important in estimating AADT using short-term traffic count data. Therefore, There have been many studies about estimating AADT. In this Paper, we tried to improve the process of the AADT estimation based on the former AADT estimation researches. Firstly, we found the factor showing differences among groups. To do so, we examined hourly variables(divided to total hours, weekday hours. Saturday hours, Sunday hours, weekday and Sunday hours, and weekday and Saturday hours) every time changing the number of groups. After all, we selected the hourly variables of Sunday and weekday as the factor showing differences among groups. Secondly, we classified 200 locations into 10 groups through cluster analysis using only monthly variables. The nile of deciding the number of groups is maximizing deviation among hourly variables of each group. Thirdly, we classified 200 locations which had been used in the second step into the 10 groups by applying statistical techniques such as Discriminant analysis and Neural network. This step is for testing the rate of distinguish between the right group including each location and a wrong one. In conclusion, the result of this study's method was closer to real AADT value than that of the former method. and this study significantly contributes to improve the method of AADT estimation.

Weather condition is one of the crucial factors affecting travelers' mode choice. Nevertheless, there are numerous indefinite traffic phenomena under various weather conditions. This study was conducted to verify the hypothesis that transit riderships decrease as precipitation increases. To clarify the relationship between precipitation and transit ridership, a seemingly unrelated regression model was employed with data such as daily precipitation and daily transit riderships of 3 transit modes (bus, metro, and shuttle bus) collected in Busan for recent 24 months. The estimation results show that transit riderships decreased as the daily precipitation increased when the daily precipitation is greater or equal to 10mm/day (0.169%, 0.101%, and 0.172% reduction in bus, metro, and shuttle bus riderships, respectively, when the daily precipitation increased by 1mm). When comparing the impact of precipitation on transit riderships by modes using a cross-equation parameter restriction test, the decrease in metro ridership is relatively insensitive to the change in precipitation. However, the negative coefficient of precipitation in the metro ridership estimation model indicates that the transit users in Busan may alter their mode to taxi or automobile and/or may give up the trip itself in bad weather condition.

Background: In cerebral palsy (CP), parents' quality of life and rearing attitude are considered possible factors that influence patients' quality of life, function level, and performance in daily activities. Despite these facts, little attention has been given to demonstrate a relation between these factors. Objects: This study aimed to demonstrate the relationship between parents' quality of life, functional level, and performance in daily activities, the quality of life of school-aged children with spastic CP. Methods: This study included 24 parents of school-aged children with spastic CP. The KIDSCREEN-52 and World Health Organization quality of life (WHOQOL)-BREF questionnaires (including physical, psychological, social, and environmental domains) were used as research tools to assess the quality-of-life profiles of the children with spastic CP and those of their parents, respectively. In addition, the function levels and performance in daily activities of the children with CP were assessed by using the gross motor function measure (GMFM) and modified Barthel index (MBI). Correlation and multiple regression analyses were performed to clarify the determinants of the quality of life of the children with CP. Results: The KIDSCREEN-52 score correlated with the total score (r=.735, p<.01) and all domains of the WHOQOL-BREF questionnaire (physical: r=.542, p<.01; psychological: r=.690, p<.01; social: r=.568, p<.01; and environmental: r=.783, p<.01). In addition, significant correlation was found between the KIDSCREEN-52 and MBI scores (r=.411, p<.05), and between the MBI and GMFM scores (r=.427, p<.05). After controlling for age, gender, paralytic type, GMFM, and MBI, the WHOQOL-BREF score ($R^2=.621$), particularly in the environmental domain ($R^2=.699$), remained independently related to the quality of life of the children. Conclusion: These findings suggest that the quality of life of school-aged children with spastic CP can be influenced by the quality of life of their parents. This study provides useful information for future studies to investigate the quality of life of children with CP.

For the past three decades, ship-to-ship collision accidents have steadily increased on the coast of South Korea by about 20% annually. Marine accidents have become more likely and more devastating in areas with increasing marine traffic and rising numbers of high-speed ships. Over 30% of the marine accidents in South Korea are concentrated in spring, since Korea's coast is often covered in dense fog at this time of the year. Fog is generated when a large temperature range exists within a day, and this daily temperature range has increased due to abnormal weather conditions. This research proposed a system for transmitting a navigator's intention utilizing electronic methods. A navigator's intention was expressed on the electronic navigation chart for easier understanding of the surrounding situation, and the effectiveness of the system was verified through practical tests.

우리 나라의 도시ㆍ산업단지 지역의 대기오염은 심각한 수준으로, 특히 미세먼지로 인한 대기오염은 스모그 등 심미적인 문제뿐만 아니라 호흡성 분진으로 인한 건강 위해성 측면에서 철저한 오염원 관리가 필요하다. 현재 우리 나라의 먼지 배출량을 보면 비산먼지의 배출량이 연소과정에서 발생되는 미세먼지보다도 큰 것으로 추정되며, 특히 이 중에서 자동차의 도로주행시 발생되는 먼지가 비산먼지 발생량 중 90 %이상을 차지하고 있는 것으로 추정된다(국립환경연구원, 2002). 차량운행으로 인하여 포장도로에서 발생하는 비산먼지 배출량은 도로 표면의 단위면적 당 silt(75$\mu\textrm{m}$이하의 입자)량, 즉 silt loading에 의해 좌우되는데 silt loading은 도시ㆍ산업단지의 체계적인 개발계획 및 대기질 관리정책을 수립에 없어서는 안 될 중요한 자료이다.
