Currently the international flight passenger visit at Incheon International Airport increased 12.4% compared to January 2017. Such increase affects on the congestion of an airport and the security check is one of the most congested area. There is a prejudice that airport security is not related to the airport service and is only a type of control that limits the quality of service. However, considering the huge impact that airport security agents have on passenger move within the airport, trustworthy, fast and kind service at airport security check is one of the most important part of airport service quality improvement. This research is an importance performance analysis of Incheon International Airport security service passenger satisfaction and its significance using IPA method. This research will contribute to the improvement of airport operation and service quality, by proving the relation between airport security and service.

It is no doubt that information technology is the key factor of national safety. Information technology is positively useful for national security such as crime prevention and detection, criminal investigation, disaster management, and national defense. However, it might be a threat to the security as we saw in the examples such as '3.4 DDoS attacks' and 'Nong-hyup Computer Network Failure.' Although the effect that information technology makes upon the national security is immense, the current legal system does not reflect these changes well. National security should be kept during 'prevention-response-recovery' process regardless it is in the online on offline. In addition, public administration for national security should be based on laws. However, the current legal system is lack of legislative basis on cyber and physical disaster, and the laws on the response to disaster might cause confusing. Therefore, this study examines the limitation of the current legal system on national security, and suggests directions for the development of the system based on the new establishment of the legal concept for 'national security'.

Virtualization technology has been widely applied in the area of computer security research that provides a new method for system protection. It has been a hotspot in system security research at present. Virtualization technology brings new risk as well as progress to computer operating system (OS). A multi-level perception security model using virtualization is proposed to deal with the problems of over-simplification of risk models, unreliable assumption of secure virtual machine monitor (VMM) and insufficient integration with virtualization technology in security design. Adopting the enhanced isolation mechanism of address space, the security perception units can be protected from risk environment. Based on parallel perceiving by the secure domain possessing with the same privilege level as VMM, a mechanism is established to ensure the security of VMM. In addition, a special pathway is set up to strengthen the ability of information interaction in the light of making reverse use of the method of covert channel. The evaluation results show that the proposed model is able to obtain the valuable risk information of system while ensuring the integrity of security perception units, and it can effectively identify the abnormal state of target system without significantly increasing the extra overhead.

It is necessary to control security management consistently and respond to an intrusion automatically in order to use the network securely in the single administrative domain. This paper presents a Shadowing Mechanism supporting a dynamic extension of security scheme and proposes an ARTEMIS(Advanced Realtime Emergency Management and Intruder Identification System), which is designed and implemented based on the suggested technique. It is possible for security management system developed on the basis of the Shadowing Mechanism to make all network components working under the same security scheme. It enhances the accuracy of intrusion tracing and automatic response through dynamic extension of space and time for security management.

This study analyzed the effects of illumination on psychological accessibility from a view of satisfaction of night use at urban neighborhood park for actual night users. For this, we have classified the effects of illumination as five sampled independent variables from 12 effects of illumination, and tested the relationship with satisfaction of night use of a dependent variable by multiple regression analysis. The results of this study are as follows; 1) The effects of illumination for night use at urban neighborhood park were divided into five factors; (1) direct effect, (2) effect of promoting use, (3) effect of ensuring security, (4) effect of preparing landscape in the night time, and (5) psychological effect. Among independent variables indicating characteristics of effects of each illumination, uneasiness at night use was high. 2) In a multiple regression model, when other conditions were not changed, the value of security of night use (X\ulcorner) had maximumly an affect on the value of dependent. And, the value of danger to meet the depraved(X\ulcorner) had minimally an affect on the value of dependent variable. 3) For the contribution of security of nigh use(X\ulcorner) and brightness of present using space(X$_4$) to satisfaction of night use(Y) of dependent variable, they had a nearly equal effect on that, and showed about 2 times importance compared to familiarity with park(X\ulcorner) and the beauty of park(X\ulcorner). Also, they showed about 7 times contribution to satisfaction of night use compared to danger to meet the depraved(X\ulcorner), which had minimally an affect on the value of dependent variable, as the most important variables. 4) For the effects of illumination on satisfaction of night use, the effect of ensuring security - pursues security of park for the general rather than security for the specific class or subject - and direct effect to offer proper brightness in using space relatively affected on it much compared to psychological effect, effect of preparing landscape in night time, and effect of promoting use. A research on the psychological effects among the variables related to illumination as well as physical circumstances such as the height, location, direction of illumination should be studied.

According to the Annex 17 to the Convention on International Civil Aviation, an appropriate authority of each contracting state has to define and allocate tasks and coordinate activities between the departments, agencies and other organizations of the State, airport and aircraft operators and other entities concerned with or responsible for the implementation of various aspects of the national civil aviation security programme. It is generally recognized that the three major parties responsible for the aviation security at an airport are appropriate government departments, airport operator and airlines. The airlines are the beneficiaries of security activities as well as the provider of security activities. So, their responsibilities have been critical in protecting civil aviation from unlawful interferences. The airport has to take leading role in implementing security tasks at airport area because the airport operator is the provider of airport facilities and services to its customer and the security activities belong to its services. The government has the responsibilities not only for establishing regulatory system but also for oversighting the implementation of aviation security activities. The paper is to review the revision of aviation security regulation and the changes of aviation security responsibilities, and costs and task assignment in Republic of Korea after September 11 event. The responsibilities, tasks and costs assigned to airlines, airport operators and government are introduced and evaluated in terms of economic fairness, effectiveness and efficiency of aviation security activities. The drawbacks of new legal system are pointed out and the suggestions to remedy them are proposed as conclusions.

The purpose of this research is to help outdoor space planning reflected real needs of apartment residents in the differentiation elements of outdoor space, by using USC trade-off game in three apartment complexes in Seoul. This game method was used to evaluate their preference, reliability of preference degree, satisfaction degree, requirement elements such as improvement, sacrifice, maintenance of present condition, and payment possibility for improving and maintaining present condition, in addition to their preference and payment possibility of differentiation of outdoor space in the apartment complex in the future. From the statical analysis, we found the following results: 1. Reliability of preference degree was valid, inasmuch as the first elements they preferred were the almost same as the last things. 2. Elements of preference were pedestrian ways, pedestrian security facilities, various athletic facilities, and variety and high-class facilities in a play ground. 3. Satisfaction degree of differentiation elements of outdoor space was low not only in total complexes but also in each complex. As a result of analysis, these elements were not satisfied with residents. 4. Most of the differentiation elements of outdoor space in three apartment complexes, except planting traditional trees, were required to improve and maintain present condition. The cost to improve and maintain these elements able to pay by them was about 2.18 million won. Through this result, these elements were not options but prerequisites for planning outdoor space in apartment complexes. 5. In the future preference elements of differentiation of outdoor space in apartment complexes were pedestrian and jogging ways, places with water, various athletic places and facilities, multi-function resting places, green spaces in experiences, pedestrian security facilities, various athletic facilities, variety and high-class facilities in a play ground, and payment possibility for these elements was about 3.20 million won.

Walking is one of human functions and has been the base of the development of human civilization. Walking ability had made the first village and urban pattern of the mankind. Cities had been constructed for pedestrian's convenience and happy life. But conventional cities have been crowded by the rapid increasing vehicles and population since material civilization had developed. On the other hand, pedestrian space has been neglected urban districts. Chose this study to suggest a direction for improvement by following the direction of the city characteristics and roadside pedestrian space. 1. Investigate the relationship and the significance and problems of pedestrian space by finding survey of the literature and discussion with those that affect the behavior of the pedestrian environment around. 2. For a comfortable pedestrian space on the improvement of the pedestrian area of space (physical and psychological) and gait characteristics, service levels and basic data. 3. Chose how to extract the most appropriate of the best alternatives presented several proposals based on the above survey of the literature data and field survey.
