운전면허 시험이 존재하는 동안 운전면허 학과시험은 필수적인 시험제도로 존재 할 것이며 향후 상당기간동안 지속적으로 산업화가 될 것으로 전망 된다. 그러나 기존의 서적을 통한 학습은 이미 출제 되었던 문제로 지정된 상황에 대한 대처 방법을 평가하는 것에 지나지 않는다. 또한 운전면허 학원에서 학과시험을 취득 할 경우 과도한 시간과 경비가 소요할 뿐만 아니라 학습효과 면에서도 비효율적인 것으로 평가되고 있다. 때문에 학습자의 능력, 연령 등을 고려한 맞춤형 운전면허 학과시험 시스템의 시급의 도입이 시급하며 이를 편리하게 학습 할 수 있는 E-Learning 멀티미디어 콘텐츠 개발이 필요하다. 이에 본 연구는 이러한 필요성에 따라 학습자의 상황에 맞는 맞춤형 교육이 이루어 질 수 있는 맞춤형 운전면허 학과시험 학습 시스템을 제안하고자 한다. 이를 통해 학습자의 문항반응의 오답분석을 통하여 최적의 평가문제와 학습콘텐츠를 선택하여 학습자에게 제공하는 과정을 반복함으로써 동적 맞춤형 E-Learning 학습방식을 제공하고, 난해한 교통 법규를 쉽고 재미있게 학습할 수 있을 것으로 기대해 본다.

The basic requirements for conducting electronic commerce include confidentiality, integrity, authentication and authorization. Cryptographic algorithms, make possible use of powerful authentication and encryption methods. Cryptographic techniques offer essential types of services for electronic commerce : authentication, non-repudiation. The oldest form of key-based cryptography is called secret-key or symmetric encryption. Public-key systems offer some advantages. The public key pair can be rapidly distributed. We don't have to send a copy of your public key to all the respondents. Fast cryptographic algorithms for generating message digests are known as one-way hash function. In order to use public-key cryptography, we need to generate a public key and a private key. We could use e-mail to send public key to all the correspondents. A better, trusted way of distributing public keys is to use a certification authority. A certification authority will accept our public key, along with some proof of identity, and serve as a repository of digital certificates. The digital certificate acts like an electronic driver's license. The Korea government is trying to set up the Public Key Infrastructure for certificate authorities. Both governments and the international business community must involve archiving keys with trusted third parties within a key management infrastructure. The archived keys would be managed, secured by governments under due process of law and strict accountability. It is important that all the nations continue efforts to develop an escrowed key in frastructure based on voluntary use and international standards and agreements.

U-learning (ubiquitous learning) systems, which deliver learning materials anytime and anywhere, allow learners to watch live lectures on PDAs, tablet PCs and notebook computers via broadband and wireless Internet. These systems have various problems; first, terminal devices are expensive, and it is difficult to maintain their efficiencies. Secondly, Internet does not guarantee quality of service (QoS), and in general it does not provide real-time services. Finally, the security of these systems is weaker in a local network than in an external network. The USB-based terminal system based on the OSGi service platform was designed as a ubiquitous system, in order to solve those problems. The USB terminals, used in this system, are inexpensive, and it is easy to maintain their performances. Also, this system solves the problems of security in a local network and provides guaranteed QoS. To accomplish this, the number of USB terminals connected to the system has to be limited according to the formula proposed in our paper. This system uses the OSGi specification as a middleware. It supports the discovery mechanism of the USB terminals, maintenance and administration of the system. Finally, this paper shows a driver's license testing system as an example u-learning application1.

More than 24.43 million people received a special pardon to mark the anniversary of Liberation Day on Aug. 15 and to commemorate other national event, during 15years(1995-2009), in this period six times of presidential pardon was implemented. The special pardon allows traffic law violator to drive again with their violation records wiped clean. But traffic records show that traffic accidents used to increase very fast in a short period by up to 3-15 percent after implementing the every massive pardons. This study explores the causal feedback relationship between presidential special pardon for traffic law violators and the occurrence of an traffic accidents using a system thinking approach and simulation modelling. Particularly, this study focused on the analysing significant negative impact of the traffic pardon on the occurrence of worrisome traffic accidents. The results of this study show that presidential special pardon have had impact on the traffic accidents as a increasing leverage of positive feedback loop and the obedience of traffic law as a decreasing leverage of negative feedback loop. Finally, this study conclude that the cyclical increasing pattern of traffic accident is resulting from the periodically conducted presidential pardons with political aims.

In this study, a direction for deregulation that can increase the use of drones in the field of spatial information is presented. Regulations and administrative procedures for drone operation showed similar procedures in Japan, the United States, and Korea, such as reporting flight equipment, driver's license, and prohibition of flying within a specific flight zone. In the United States, policies to encourage the use of commercial drones have been implemented, and Japan has slightly tightened regulations on drone operation to protect the Olympics and important national facilities. As a result of the study, in the area where drone operation is restricted for geospatial data construction, Korea was setting the largest area, and GIS analysis showed that Korea's drone flight restricted area was more than 19.4% of the country's land area. In order to increase the utilization of drones in the construction and utilization of spatial information in the future, it is necessary to reset the drone flight restriction zone and reduce the area of the drone flight restriction zone. In addition, it was found that Korea is the only country that has formal and specific regulations on geospatial information security management. In order to increase the construction of geospatial information using drones, it is necessary to ease GSD (Ground Sample Distance)regulations.

This study was designed to verify reliability and feasibility by analyzing elderly drivers' ability test tools for older drivers aged 65 or older, which were improved in 2018 and are currently being conducted by the Korea Highway Traffic Authority. Only those aged 65 or older who voluntarily applied to the elderly driving ability evaluation system implemented by the Seoul branch of the Korea Highway Traffic Authority. The research was conducted for about 50 days until Aug. 31, 2018, starting with the registration and inspection of the first study subjects. The analysis performed a correlation analysis with existing tools and cognitive testing tools (MMSE_K) to determine their feasibility and reliability as an improved tool in 2018. As a result, the first, the speed distance, time-space memory, and dispersionism of each sub-component of the old version showed statistically significant static correlation with the sub-factor of the current version. Persistence, on the other hand, was not statistically significant to the current version. The limitations of this study were as follows. Most of the people in the study were highly educated and residents in the metropolitan area. Therefore, it is likely that the results of MSE_K, which checks cognitive and judgment skills, have been upgraded. Also, cognitive tools that are measured by computers are likely to have real measurement errors for generations who are not familiar with computers. Therefore, it is expected that improvement and development of tools for improving the limit points at the site and assessing actual operation capability will be required.

Purpose : We investigated the career choice and the employment preparation of emergency medical technology (EMT) students. The results of study will provide the base information about the consciousness for career choice and employment of the EMT students. Method : We conducted 1,586 surveys from 665 students at six four-year colleges and 921 students at seven three-year colleges, from Aug. 27th to Oct. 31st in 2010. The result was analyzed by SPSS 18.0 using description statistics, t-test, ANOVA, Scheffe and Pearson correlation coefficient. Result : The general characteristics showed male 50.2% and female 49.8%, and first grade 34.6%, second grade 27.4%, third grade 28.2%, and fourth grade 9.8%. The 53.9% of students had experienced the hospital training and the 44.8% did the fire station training. For the choice of job, there were the 61.8% student who hope to enter the employ in fire station or public service, while 25.7% students hope to be employed in hospitals. The reason for a wish job were 'majors-related job' in 18.2% students, 'employment stability' in 17.2% and 'hit on the aptitude and talent' in 16.7%, 'appropriate salaries' in 15.9%. In the questionnaire of the University what to assist you for job preparation, they chose the 'support for get major related license', 'support for officer exam preparation' and 'support of foreign language study' in 34.6%, 16.8% and 16.6%, respectively. For achieved licence, they had a driver's license in 53.9%, BLS (basic life support) provider in 20.3%, life guard in 16.2% and scuba in 8.8%. The statistically significant correlation was identified between the awareness of University that provides job information and one's career awareness (r= .203, p<.000), the awareness that University provide job information and one's confidence in employment (r= .236, p<.000), and one's career awareness and one's confidence in employment (r = .356, p = .000). Conclusion : The most of EMT Students are well conscious of the their future employment and has prepared career to be employed their preference job.

Currently the IoT (Internet of Things) environments and related technologies are being developed rapidly through the networks for connecting many intelligent objects. The IoT is providing artificial intelligent services combined with context recognition based knowledge and communication methods between human and objects and objects to objects. With the help of IoT technology, many research works are being developed using the C-ITS (Cooperative Intelligent Transport System) which uses road infrastructure and traveling vehicles as traffic control infrastructures and resources for improving and increasing driver's convenience and safety through two way communication such as bus-only lane and license plate recognition and road accidents, works ahead reports, which are eventually for advancing traffic effectiveness. In this paper, a system for deciding whether the traveling vehicle is possible or not to drive on bus-only lane in highway is researched using the lane and number plate recognition on the road in C-ITS traffic infrastructure environments. The number plates of vehicles on the straight ahead and sides are identified after the location of bus-only lane is discovered through the lane recognition method. Research results and experimental outcomes are presented which are supposed to be used by traffic management infrastructure and controlling system in future.

The main premise of this study is that the assurance on human rights of the mentally ill is contradictory to 'the greatest happiness of the greatest number' or 'therapeutic benefits'. Accordingly this study aims to find out the conceptual framework of assurance and restriction on human rights of the mentally ill. Using qualitative method, this study conducted the in-depth interview with 10 general public, 9 professionals, 6 mentally ill regarding the several issues of human rights included long-term hospitalization, restriction on driver's licence, involuntary hospitalization, restriction on communication in psychiatric ward. Research results are as follows ; two sets of dimensions are inferred from the analysis of interview transcript. First dimension is the focus of justification, ranging from the emphasis on positive consequences influenced to 'the greatest numbers'(the utilitarian thought) to the emphasis on assurance of rights without any conditions(the deontological thought). Second dimension is the locus of decision, raging from the formal system included the professionals and the government agency to the informal system included the families and the mentally ill. And there are differences in attitudes toward assurance and restriction on rights of the mentally ill among general public, professionals, and the mentally ill. In detail, general public regarded that 'involuntary hospitalization' and 'restriction on driver's license' which are apt to be directly harmful to people must be justified by consequence-centered and decided by the formal system, while 'long-term hospitalization' which is less harmful to people could be justified by right-centered and decided by the formal-system. And they thought that 'restriction of communication' could be justified by right-centered and decided by the informal system. Based on the findings, this study would conclude that practical guidelines for the promotion of human rights of the mentally ill must be developed.

Currently, there are some aptitude test systems for older drivers in Korea. However, there are no methods and systems to evaluate the real driving ability for older drivers based on filed driving test. This study was conducted to investigate the availability to use the driving course test used for driving license for identifying difference in driving ability of older and non-older drivers. For the research purpose, filed experiments were conducted using the real driving course test site and evaluation times used in the field. In particular, driving behavior data that obtained from the experiments for two driver groups, older and non-older drivers, were analyzed and compared. From several statistical analyses of driving ability and vision and cognitive ability, it was found that the currently used driving course test site and evaluation times were not appropriated to identify driving ability deficiency of older drivers. To solve the problem, this study developed five evaluation items to identify driving ability deficiency of older drivers using the currently used driving course test site. It was also found that the developed five evaluation items have statistically significant correlation with vision and cognitive ability.
