Nowadays, with increase of seafood consumption, there have been increasing reports of defective seafood products. There have been incidents of red drum (Sciaenops ocellatus) being sold as red seabream (Pagrus major). In this study, we sought to develop and validate species-specific PCRs to differentiate between P. major and S. ocellatus to prevent the sale of S. ocellatus as P. major. Primers for P. major were designed to bind 12s rRNA and those for S. ocellatus were designed to bind 16s rRNA. Multiplex PCR showed a 468 bp amplicon for P. major and a 181 bp amplicon for S. ocellatus. The limit of detection of P. major and S. ocellatus was present at 1 ng each. The developed primers were validated with 19 P. major samples of food items purchased through the internet. Using this monitoring method, the experimental results and tested species were in agreement. Hence, the developed multiplex PCR method is considered reliable to authenticate P. major and S. ocellatus.

Recently in the construction business construction companies has been ordered to survive in the terriblly competitive environment. Aa a result, most of the project with low-priced contract needs a speedy progress during all construction period. For the last five years major incident frequently occurs and results in the death of 189 workers at major top 6 construction builders. In most recent 10 years, the cause of major incidents happened in construction company is the speedy construction work that is affecting on the safety management. To prevent these accidents in the speedy construction work, four factors were chosed and analysed such as the personnel/organization, the working budget, the subcontractor selection and the employee motivation. The head office taked the support plan and tested it at the pilot work site. It showed a reduced accident and the harmful factors can be eliminated. It should be able to apply to the field to secure safety and prevent accidents.

Recent cyberthreats are emerging as big issues that need to be addressed to both developed countries and South Korea. Our government has implemented and established comprehensive measures whenever major incidents were happened. It is still insufficient, even though the national and social level of cybersecurity are improved with continuous investments and efforts to strengthen the country than in the past. Comprehensive measures have been exposed to limit the effectiveness because they are focused on short-term measures. In this paper, we try to analyze the problems of incidents and assess the implementation process of establishing comprehensive measures in order to suggest ways ultimately to improve the country's overall level of cybersecurity.

Users of passenger ships and cruise ships are rapidly increasing year by year, and the needs of the floating architecture are newly come out. But the studies about the passengers' safety and the countermeasures against incidents on board the ships are rare, although the ships' incidents are occurred averagely 15 cases per year during last 10 years. For the purposes of the analysis of the safety consciousness and gathering the some of input data for evacuation simulation for Korean passengers on board ships, this study performed surveys targeting ordinary 394 passengers who are not specially trained and/or accustomed with onboard living conditions. The results are the followings. The reliability on ships' safety is surveyed as 32.3%. Only 14.6% of respondents are aware that there were safety education on board ship during sailing. And 42.2% and 40.9% of respondents answered that they saw the map of emergency routes and knew where the life boats are, respectively. And 73.3% select crews' direct or in-direct(like announcement by indoor broadcasting system) guidances as the most effective evacuation method.

Game is the latest type of Gesamtkunstwerk encompassing humanistic and engineering creativity. Nevertheless, Korea's game industry faces a crisis. The purpose of this study is to consider positive emotion-inducing effects as a way to deal with it. Among others, storytelling of , one of the most representative MMORPG games in the world, was selected for the study on various positive emotion-inducing effects. In the story of , the view of the world, characters and incidents are vital to the game and the study is focused on their emotion-inducing effects among the users based on actual examples. As a result, it was confirmed that the positive emotion-inducing storytelling would provide a possibility to reduce negative sentiment towards games, address crisis Korea's game industry faces, and interact with gamers in a positive direction.

Recent personal data breach incidences draw the public's attention to their privacy and personal rights. The new personal data protection law effective in September 2009 imposes additional legal responsibility on personal data controllers and processors. For instance, if a data breach occurs, this new law requires that the processors must notify individuals (data subjects) and data protection authorities of the nature of incidents. This research reviews the U.S. forty six state laws and related acts, and offers a framework for managing incidents. This framework includes five major components: (1) type of personal data required to be reported and notified, (2) the ultimate subject notifying data subjects, (3) event occurrence and notification time phases, (4) notification message details, and (5) direct/indirect communication media. Along with this framework, we also offer directions for effective/manageable guidelines on data breach notification act.

In case of a dangerous situation, the roof, which serves as an emergency exit, must be open in case of fire according to the Fire Act. However, when the roof door is opened, it has become a place of various incidents and accidents such as illegal entry, crime, and suicide. As a result, it is a reality to close the roof door in terms of facility management to prevent crime, various incidents, and accidents. Accordingly, the government is pushing to legislate regulations on housing construction standards, etc. that mandate the installation of electronic automatic opening and closing devices on rooftop doors. Therefore, in this paper, an intelligent emergency door opening/closing device system is proposed. To this end, an intelligent emergency door opening and closing system was developed by linking wired and wireless access counting and AI image analysis. Finally, it is possible to build a wireless communication-based integrated management platform that provides remote control and history management in a centralized method of device status real-time monitoring and event alarm.

Likelihood analysis was used for the revision of release probability/frequency in chlorine Injection facilities used in chlorine process. Typically these facilities consist of pressure cylinder, vaporizer, pipeline, measuring equipment and safety equipment. This paper described the incident scenarios considered, likelihood analysis procedure and the selection and application of basic events and for failure rates of mechanical components. Human errors were also considered. The major objective of this paper is to estimate the likelihood of each determined incident scenarios. We estimated failure rates of mechanical components based on likelihood analysis procedure. Human errors were also considered. It was estimated to have $5.73{\times}10^{-5}\;Cl_2$ leak per year during the major $Cl_2$ handling process. The probability of failure in scrubber system was $4.11{\times}10^{-2}/demand$.

We estimated failure rates of mechanical components based on likelihood analysis procedure. Human errors were also considered. It was estimated to have $5.73{\times}10^{-5}$ $Cl_2$ leak per year during the major $Cl_2$ handling process. The probability of failure in scrubber system was$4.11{\times}10^{-2}$/demand.

Charles Lindbergh has experienced the uncontrolled situation of the aircraft while he was asleep with open eyes during his Atlantic crossing flight around 20 hours after departure from the New York in 1927 because of the fatigue. According to the NTSB(National Transportation Safety Board) reports, about 40 incidents are related fatigue in each year. The sleep loss is the most wanted item for the NTSB and may cause the similar effect as the alcohol does. The fatigue may affect the management of the threats and errors especially during take-off and landing. In this study, threats and errors of major accidents that NTSB analysed fatigue as a causal factor will be identified in order to understand the seriousness of fatigue.
