Currently, the departments related to security and secretary service exist in 18 universities and 30 colleges in Korea in order to raise professional security and secretary personnel. Among the 18 four-year colleges in Korea, only two of them have the ethics course include in their curriculum. Also, among the 31 two-year colleges, only three of them have the ethics course included in their curriculum. Besides, as some private security and guardian companies were recently utilized in illegal actions of the rich and ruling class, contradicting their original purpose of existence, many people point out their downfall as a ?forced private army.? As a professional job, if security secretaries take advantage of the knowledge and top-secret technologies and use them for non-ethical purposes, the effect of the damage is far more serious than other fields of jobs. Therefore, taking this event as a turning point, the contract contents and the task area between the client and the security and secretary company must become more transparent in order to prevent illegal actions, and also for the people working in the security and secretary service area, it is necessary to establish a firm ethical consciousness in order to behave appropriately in their working environment. Therefore, this study examines the proper direction of work ethics of the people working in the security and secretary service according to the professionalization of their field, and also aims to propose an appropriate work ethic system such that they will not become an unfortunate victim of various scandals anymore. To do so, the concept of work ethics in professional jobs was examined; and after the code of ethics that reflect the ethical value system of each professional job was reviewed, the study suggested a specific solution for establishing the codes of ethics for security and secretary service.

Threat intelligences collected from cyber incident sharing system and security events collected from Security Information & Event Management system are analyzed and coped with expanding malicious code rapidly with the advent of big data. Analytical classification of the threat intelligence in cyber incidents requires various features of cyber observable. Therefore it is necessary to improve classification accuracy of the similarity by using multi-profile which is classified as the same features of cyber observables. We propose a multi-profile ensemble model performed similarity analysis on cyber incident of threat intelligence based on both attack types and cyber observables that can enhance the accuracy of the classification. We see a potential improvement of the cyber incident analysis system, which enhance the accuracy of the classification. Implementation of our suggested technique in a computer network offers the ability to classify and detect similar cyber incident of those not detected by other mechanisms.

This work investigates the potential of in-cylinder thermal stratification and fuel stratification for extending the operating ranges in HCCI engines, and the coupling between thermal stratification and fuel stratification. Computational results areemployed. The computations were conducted using both a custom multi-zone version and the standard single-zone version of the Senkin application of the CHEMKINII kinetics rate code, and kinetic mechanism for di-methyl ether (DME). This study shows that the potential of thermal stratification and fuels stratification for extending the high-load operating limit by a staged combustion event with reduced pressure-rise rates is very large. It was also found that those stratification offers good potential to extend low-load limit by a same mechanism in high-load. However, a combination of thermal stratification and fuel stratification is not more effective than above stratification techniques for extending the operating ranges showing similar results of fuel stratification. Sufficient condition for combustion (enough temperature for) turns misfire in low-load limit to operate engines, which also leads to knock in high-load limit abruptly due to the too high temperature with high. DME shows a potential for maximizing effect of stratification to lower pressure-rise rate due to the characteristics of low-temperature heat release.

This article attempts to describe and analyze discussions on the matter of ex tunc effect or a ex nunc effect of rescission under Korean law in comparison with those under the CISG). In addition, it tries to scrutinize the various rules on the right to damages as an effect of rescission in a comparative way. Furthermore, it compares the various rules of Korean law with the CISG as to the right to damages and evaluates them in light of the discipline of comparative law. It maintains that the liquidation theory in Korean law is more close to the CISG in that there is no ex tunc effect in rescission and in other aspects. It also argues that the construction of the effects of rescission in accordance with the liquidation theory is more plausible when one considers Korea is one of the contracting states of the CISG. In addition, the theoretical analysis and the comparative study with the CISG shows that the insistence of ex nunc effect and its interpretation on the scope of damages extends to damages for expectation interest. It is also submitted that the position under the CISG on the assumption of ex nnuc effect, is regretted in that the restitution in value of the goods in the event of impossibility of the physical restitution is not allowed in some cases which the damage claims can not be awarded for the seller due to the application of the CISG Art. 79.

With an elevator supply and demand increases, It has been enlarged various requirements for the safety of the elevator. Elevator safety requirements can be the ability to respond to emergencies quickly. Recently, QR code was attached to all elevator for the elevator safety and it is established by law for the Elevator rescue work. And also the elevator system is seeking to utilize more secure elevator with mandatory installation of CCTV and direct call devices. However, CCTV and direct call service is operating on an individual method and it has not been proposed integrated model. In this paper, we propose the safety elevator integration model with CCTV, direct call service and remote control based on smart phone. Using the proposed model, we can be improved the efficiency of maintenance and ability of prompt action in the event of a disaster.

In the event of a building fire, it is important to control the smoke generated to ensure the safe evacuation of occupants. A natural smoke ventilator should be installed to exhaust the fire smoke in accordance with the Korean building Act and Code. On the other hand, the present law does not specify the contents regarding natural smoke ventilators sufficiently. The problems that occur in various parts, such as the installation target, installation location, free area, and the control and maintenance of natural smoke ventilators need to be solved. In this study, the problem of the current system was examined through domestic and foreign standards, preliminary research, and field investigations. In addition, suggestions for improvement are provided.

The strong protection method of radiation emergency preparedness is the evacuation when a great deal of radionuclide material is released to environment. Required factors for evacuation time estimate of Ulchin nuclear power plant site were investigated. The traffic capacity and the traffic volume by season were investigated for the traffic analysis and simulation within EPZ of Ulchin site. As a result, the background traffic volume by season were established. The NETSIM code was applied to simulate for 12 scenarios in the event of normal traffic/summer peak traffic/winter peak traffic, daytime/night, and normal weather/adverse weather conditions. The results showed that the evacuation time required for total vehicles to move out from EPZ took generally $210\~315$ minutes. The evacuation time took longer about 45 minutes at night than in the daytime, and 45 minutes in adverse weather than normal condition.
