The trust issue on the safety of autonomous vehicle is a very important in regard to the demand generation of relevant industries. To secure the trust, The study of legal liability issue should be prior to an accident of the autonomous vehicle. In civil law, it is possible to make the automobile manufacturer take legal responsibility with the "Product Liability Act". Whereas, in criminal law, it is difficult to make him take legal responsibility since the criminal law holds the actor responsible. To solve these problems, this article proposes the establishment of the "Special Act on Autonomous Vehicle". Also, there is a demand for building infra structures and system to operate the (fully) self-propelled vehicle and establishing "certification" systems.

It is very important to construct advanced recall systems in aspects of developing auto industry through strengthening international competitive power, as well as protecting the lives from traffic crashes by vehicle defects. Under the self-certification system, there may be high probability to be defected vehicles because vehicles are sold without testing and approval of governmental sides, even though the system was introduced to give an autonomy to manufactures. Accordingly, it is not optional, but essential concerns to build advanced recall system. As a result of analysis, manufacturers and consumers ask for improvements of domestic recall systems. In this study, policy guidelines were provided on the basis of analyses on several regulations and questionnaires of consumers and manufacturers. The policy guidelines are clearness of recall subjects, prompt collection of vehicle defect information, objective determination of vehicle defects, continuous monitoring of vehicle recalls, etc.

The importance of protection for data and information is increasing by the rapid development of information communication and network. And the concern for protecting private information is also growing due to the increasing demand for lots of services by users. Asymmetric cryptosystem is the mainstream in encryption system rather than symmetric cryptosystem by above reasons. But asymmetric cryptosystem is restricted in applying fields by the reason it takes more times to process than symmetric cryptosystem. In this paper, encryption system which executes authentication works of asymmetric cryptosystem by means of symmetric cryptosystem. The proposed cryptosystem uses an algorithms combines that combines block cipherment with stream cipherment and has a high stability in aspect of secret rate by means of transition of key sequence according to the information of plaintext while symmetric/asymmetric cryptosystem conducts encipherment/deciphermeent using a fixed key. Consequently, it is very difficult to crack although unauthenticator acquires the key information. So, the proposed encryption system which has a certification function of asymmetric cryptosystem and a processing time equivalent to symmetric cryptosystems will be highly useful to authorize data or exchange important information.

The subjects included employees at 426 school foodservices in Busan. The mean job engagement was significantly different in the reason that cooks chose this profession(p<0.05), and readiness to quit(p<0.001). The mean job stress was significantly different in different age groups(p<0.01), cooking certification(p<0.01), reason that cooks chose this profession(p<0.01), and readiness to quit(p<0.05). The mean job stress was significantly different in the reason cooks chose this profession(p<0.01), and readiness to quit(p<0.05). In terms of the level of satisfaction of coworkers, the subfactor of job burnout, 'self-confidence' and 'achievement' had positive influences (p<0.01) and for the level of satisfaction of the work, it had positive influences on 'achievement'(p<0.01) and negative influences on 'exhaustion' (p<0.01). In terms of the level of satisfaction of co-workers and work, the subfactor of job engagement, 'absorption' had positive influences(p<0.01). Among the level of job satisfaction, for the level of satisfaction of pay, the subfactor of job stress, 'unstable job' had negative influences(p<0.01) and 'role conflict' had positive influences(p<0.05). For the level of satisfaction of co-workers, the subfactor of job stress, 'role conflict' had negative influences(p<0.01), and for the level of satisfaction of work, 'inappropriate circumstance' and 'unstable job' had negative influences (p<0.01).

This study analyzes inspection results of ships by Port State Control. Particularly, this research focuses on a detention trend of vessels that registered to Korean Register of Shipping. In order to conduct this research, we have searched 170 ships that got a detention with a Code-30 within recent 46 months period. The deficiencies of the detentions are inspected by ship types, ship years, flags, ports inspected, and criteria. Moreover, we categorized the deficiencies for the detentions into 17 types for internal and external inspections. As the results of the comparison study, bulk and general cargo carriers dominate the portion of detentions by almost 66 percent. Self-induced detention due to a lack of preparation by crews and company support are the main reasons of repeated detentions from the same type ships. Ships between six and ten years old show the lowest detention rate by 4 percent whereas ships less than five years old generate the highest detention rate by 22 percent. The main categories of the detentions from ships less than 5 years old are a lack of documentation and certification, and the clues support our opinion that owners and crews may neglect to prepare the inspections because their strong confidence for the ship condition due to young ship age. As a result of a great effort of Korean government and shipping companies to reduce a detention rate, the detention rate has been recently reduced to 0.3 percent. The results also require companies with the flag of convenience ships to spend more effort to reduce the detention rate, too. We expect that using social networking service by Korea Register will lower the detention rate by sharing relevant information real-time to ships and owners.

The purposes of this study which was conducted by inquiring into some curricula for Emergency Medical Dispatchers(EMDs) are to introduce a curriculum into Korea and develop a textbook for training of the EMDs in Korea. The conclusions from this study were summarized as follows; (1) There are some professional demands in our Emergency Medical Dispatch field therefore, now it is necessary to set up an education system for the EMDs in Korea and give them a suitable name to this change. (2) Some historical turning points which are condensed from the developmental process in the USA. including "Medical Self Help" with no formal dispatch protocols, Medical Priority Dispatch System, Practice Standard, Dispatch Protocols will serve as a good reference for establishing and education system for the EMDs. (3) To effectively train the EMDs in Korea, we needed to be introduced to Emergency Medical Dispatch : National Standard of Curriculum from the U.S. Department of Transportation & the National Highway Traffic Safety Administration which is made up Basic Emergency Medical Concepts, Information Gatherin & Dispatch, Introduction to the Emergency Medical Dispatch Protocol Reference System(EMDPRS) & 32 Chief Complaint Types. (4) The introduced curriculum closely related to the medical director, the direct indirect medical control, the scope of practice in the USA, should be revised for the Emergency Medical Service System of Korea. But to reduce the developmental process & time, it is necessary to postpone the consideration on these factors until publishing a new textbook. (5) This study which gives the cornerstone about some developmental methods on textbook for EMDs will be helpful to build up an education system for EMDs such as Curriculum, EMD Certification, National Academy of Emergency Medical Dispatch to fit the Emergency Medical Service System of Korea in the future.

Jeju Special Self-Governing Province has the natural assets resulting in UNESCO World Biosphere Reserve, World Heritage Listed and World Geopark Certification, so the principle of 'Conservation First Development Later' has been set up for the vision of environmental policy to preserve these assets. This case study has been carried out to investigate the realization of the principle of 'Conservation First Development Later' for the development projects performed environmental impact assessment from 1994 to 2012 in Jeju Province, using geographic information systems(GIS). The Jeju Province has its own ordinance to consult and operate an environmental impact assessment(EIA) system. In particular, the conservation area, such as, Absolute/Relative Conservation Area and Underground Water, Ecosystem and View Conservation Zone, has been assigned and managed specially to conserve the natural environment. The 179 projects has been performed EIA for last 18 years in Jeju Province, and then the Absolute Conservation Area has been included in 22 projects and the Relative Conservation Area has been included in 34 projects. However, the 2 projects only have included the Absolute Conservation Area for 7 years after 2005. This result suggests that the application of the principle for the Absolute Conservation Area is strengthened gradually. On the other hand, the 17 projects and the 24 projects have included the Underground Water Conservation Zone assigned grade 1 and 2, respectively, and the number has been increasing after 2004. The results show that it needs to strengthen the application of the principle for this Zone. And the Ecosystem Conservation Zone assigned grade 1 and 2 have been included in 1 project and 9 projects, respectively. It is considered from this result that the principle is realized successfully for the Ecosystem Conservation Zone. In addition, it could be known that the principle is applied well for the View Conservation Zone, in this study.
