Internet phone, communication cost and easy-to-use low-cost compared to the PSTN is a mobile phone of a conventional, and use of the Internet phone is spreading. Construction as part of the broadband convergence network(BCN), Internet service provider(KT, SKT, LG) has converted to Internet phone telephone network to all government agencies. In addition, members of the public also have an Internet phone service that you are using. In this paper, we analyze the hacking attack on IP-PBX in the IETF SIP-based that are used in Internet telephony, to the study. The test bed is constructed in the same way as the Internet telephone system to perform studies carried hacking attacks on IP-PBX, analyze the results and to extract evidence forensics. When used in crime by hacking the Internet telephone, we propose a method which can be used as evidence in forensic having legal effect.

The lava-calcification which was found in Geunjisul located in Jeju-do (Korea) was investigated to analyse the cause of calcification through the internal factor of cave structure and surroundings in company with relevant ecological system. The volcanic cave is degenerated after formation from volcano lava extravasation, however, the cave became more stronger with solidification and petrification by the reinforced structure of calcification as the cement in concrete buildings unprecedentedly if the lava-calcification occurred in the cave. Such a Progressive Phenomena of lava-calcification was verified in progress first in Geonjigul located at Hyubjae-ri, but those would be found in other simiiar case of caves distributed and connected with seaside of shelly sand beach.

According to the result of related studies, the degradation of human performance has been revealed as one of the most significant causes resulting in the safety of any human-involved system. This means that preventing the occurrence of accidents/incidents through avoiding the degradation of human performance is prerequisite for their successive operation. To this end, it is necessary to develop a plausible tool to evaluate the complexity of a task, which has been known as one of the decisive factors affecting the human performance. For this reason, in this paper, the complexity of tasks to be conducted by KTX drivers was quantified by TACOM measure that is enable to quantify the complexity of proceduralized tasks being used in nuclear power plants. After that, TACOM scores about the tasks of KTX drivers were compared with NASA-TLX scores that are responsible for the level of a subjective workload to be felt by KTX drivers.

Objectives: This study is based on Public Care Service for Chronic Diseases in Incheon Metropolitan City featuring Health-Point Service. It is objective to evaluate whether the service could improve self-management ability of hypertension and diabetes patients. Methods: The knowledge about diabetes and hypertension, which can be improved by educational intervention, is considered as one of the most important factor for self-management ability. While the education service have been conducted, 194 patients who have been diagnosed as hypertension and diabetes within 3 months were included. They completed questionnaires two times within 4 months period, which give information about the knowledge, service registration and education experiences. For further inspection, 396 patients who had been diagnosed formerly were studied by cross-sectional analysis. Results: Regardless of service registration or educational intervention, there wasn't statistically meaningful difference between the initial and the follow-up assessments on the knowledge. However, when investigating formerly diagnosed patients, educated patients had better knowledge on hypertension compared with non-educated patients and registered patients, educated patients had the better knowledge on diabetes compared with non-registered patients, non-educated patients. Additionally, analyzing each questions, educated patients got higher grades in questions about definition of hypertension, diabetes managements which they can practice in daily lives. Conclusions: It is probable that long-term service registration and education experiences could improve the knowledge and self-management ability.

The NH-NongHyup network and servers were paralyzed in 2011, in the 2013 3.20 cyber attack happened and Classified documents of Korea Hydro & Nuclear Power Co. Ltd were leaked on December in 2015. All of them were conducted by a foreign country. These attacks were planned for a long time compared to the script kids attacks and the techniques used were very complex and sophisticated. However, no successful solution has been implemented to defend an APT attack thus far. Therefore, we will use big data analytics to analyze whether or not APT attack has occurred in order to defend against the manipulative attackers. This research is based on the data collected through ISAC monitoring among 3 hierarchical Korean defense system. First, we will introduce related research about big data analytics and machine learning. Then, we design two big data analytics models to detect an APT attack and evaluate the models' accuracy and other results. Lastly, we will present an effective response method to address a detected APT attack.
