Purpose of this study is examining closely special guard's Organizational Culture and job stress and relation of Organizational Commitment. This study established to special guards who is working at the capital region (Incheon) airport in 2011, and sample used finally on interpretation analyzed being 203 people, and uses Purposive Sampling Method. Analytical method executed Frequency Analysis, Factor Analysis, Reliability analysis, correlation analysis Multiple Regression Analysis using SPSSWIN ver.18.0. Reliability of questionnaire appeared Cronbach's ${\alpha}$ value more than .671. Conclusion proved in this study is as following. First, special guard's formation culture affects to Job Stress. In other words, stress about compensation career development increases if the development, hierarchically organized is not formed. On the other hand, job special quality, human relations stress decreases if developmental culture is form ed, and if culture is formed developmental, the mutual agreement, role stress decreases. Second, special guard's Organizational Culture affects in Organizational Commitment. That is, if is formed developmental and hierarchically organized, rises the Affective Commitment, Continuance Commitment, Normative Commitment. Third, special guard's job stress affects in Organizational Commitment. That is, if compensation career development is achieved unfairly Affective Commitment, Continuance Commitment is low. On the other hand, if own business is achieved spontaneously pre sent, Affective Commitment, Normative Commitment appears high.

As the need for anti-terrorism legislation has been continuously argued, Anti-terrorism act has been enacted and enforced. On the other hand, there still remain a lot of points to be discussed regarding the definition of the concept of terrorism, matters of human rights violations, strengthening authority of the investigation and intelligence agencies, and mobilization military forces for the suppression of terrorism. Also, reviewing Anti-terrorism act and its enforcement ordinance draft, this legislation seems to regulate terrorist groups like IS. If so, in the case of terrorism of North Korea or domestic anti-government organizations, whether this law would be applied could become an issue. In the case of terrorism of North Korea, Ministry of National Defense has a right of commandership in the military operations, however, it is also possible to apply the article 4 of Natural Security Act a crime of performing objective-or a crime of foreign exchange on Criminal law as legal grounds for not military terrorisms but general investigations. Therefore, it is necessary to involve consideration about this matter. Furthermore, in the view of investigation, Anti-terrorism act and its enforcement ordinance draft do not mention Supreme Prosecutors Office and Ministry of Justice that conduct investigations. In the case of terrorism, the police and prosecution should conduct to arrest criminals and determine crimes at the investigation stage, however, any explicit article related to this content in Anti-terrorism act and its enforcement ordinance draft was unable to be found. Although Anti-terrorism act is certainly toward preventive aspects, considering some matters such as prevention, actions on the scene, maneuver after terrorism, arresting terrorists, investigation direction, cooperation, and mutual assistance, it is necessary to reflect these contents in Anti-terrorism act. In other words, immediately after terrorists attacks, it is possible to mobilize the military operations by Integrated Defense act in order to arrest them in the case of military terrorism. Nevertheless, because both military terrorism and general one are included in the investigation stage, it needs to begin an investigation under the direction of the prosecution. Therefore, above all, a device for finding out the truth behind the case at the investigation stage is not reflected in the current Anti-terrorism act and its enforcement ordinance draft. Accordingly, if National Intelligence Service approaches information at the prevention level in this situation, it may be necessary to come up with follow-up measures of the police, the prosecution, and military units.

A PAK(Password-Authenticated Key Exchange) protocol is used as a protocol to provide both the mutual authentication and allow the communication entities to share the session key for the subsequent secure communication, using the human-memorable portable short-length password, In this paper, we propose distributed key exchange protocols applicable to a smartcard using the MTI(Matsumoto, Takashima, Imai) key distribution protocol and PAK protocol. If only one server keeps the password verification data which is used for password authentication protocol. then It could easily be compromised by an attacker, called the server-compromised attack, which results in impersonating either a user or a server, Therefore, these password verification data should be distributed among the many server using the secret sharing scheme, The Object of this paper Is to present a password-based key exchange protocol which is to allow user authentication and session key distribution, using the private key in a smartcard and a password typed by a user. Moreover, to avoid the server-compromised attack, we propose the distributee key exchange protocols using the MTI key distribution protocol, And we present the security analysis of the proposed key exchange protocol and compare the proposed protocols with the existing protocols.

Since the introduction of AEO certification in South Korea in 2008, 516 areas have been AEO certified based on a report dated December 31st, 2013. The number is expected to increase drastically as more and more companies strive to obtain the AEO certification. In this regards, this study is designed to contribute to the further invigoration of the AEO certification system as well as to propose directions to improve companies' performance in a practical point of view. To do so, the writer reviewed the past studies done in the relevant subjects in order to 1) grasp the principal subject, 2) catch the areas with insufficient information/lacking points, and to 3) get a focus on future directions on how additional research should be conducted. An analysis of the past studies proved that prior to the introduction of the AEO certification, the focus of the studies were to present the reasons as to why AEO should be introduced, the benefits of AEO, and a comparative analysis of countries already in wide usage of the AEO system. Studies done after the introduction of AEO (that is, after 2008) focused mainly on invigorating the system into the market. Compared to the previous studies, this study will present a distinct conclusion by breaking down the major points of each study on a year-by-year basis and studying them in total in order to provide an even more practical direction in the future of AEO in South Korea.

In Germany, North Sea and East Sea possess significant meaning in many aspects. North coast has an important economical significance to North Sea Gulf States. There are a number of harbors and manufacturing facilities in this area. Agriculture is also developed. East sea, where sea water and river water mingle. has a problem that it can not control harmful substances as fast as the North Sea due to its geographical location of being connected with the North Sea as a narrow water. To protect from big and small ship accidents and pollution sources, East Sea and North Sea have enacted HELKOM Convention and OSPAR Convention, respectively. Moreover, Denmark and Germany have made cooperation on tugboats in the occurrence of shipment accidents through the LethGer-Plan and DenGer-Plan. In 1998, after the Pallas accident that occurred near Bremen, the need to improve cooperation among each states on usable resources for ocean security has been increased in Germany. Consequently, the federal government and gulf state governments associated and organized the so called, "Havarie-Kommanando Ship Accident Measure Unit". Haravarie-Kommanando is a federal-state associated organization that deals with affairs that controls national operation and mobilization of ship accident related organizations unitively when serious ship accidents occur. Moreover, federal and state participant organizations, each shipping agencies and Wiking-Helicopers-Services, a helicopter agency, are cooperating well. Also, mutual assistance with the most prominent passenger agency called Scandlines, ARGE Kuestenschutz(Germany-Denmark shipping agency) is making progress as well.

Recently, the damage of cyber attack toward infra-system, national defence and security system is gradually increasing. In this situation, military recognizes the importance of cyber warfare, and they establish a cyber system in preparation, regardless of the existence of threaten. Thus, the study of Intrusion Detection System(IDS) that plays an important role in network defence system is required. IDS is divided into misuse and anomaly detection methods. Recent studies attempt to combine those two methods to maximize advantagesand to minimize disadvantages both of misuse and anomaly. The combination is called Hybrid IDS. Previous studies would not be inappropriate for near real-time network environments because they have computational complexity problems. It leads to the need of the study considering the structure of IDS that have high detection rate and low computational cost. In this paper, we proposed a Hybrid IDS which combines C4.5 decision tree(misuse detection method) and Weighted K-means algorithm (anomaly detection method) hierarchically. It can detect malicious network packets effectively with low complexity by applying mutual information and genetic algorithm based efficient feature selection technique. Also we construct upgraded the the hierarchical structure of IDS reusing feature weights in anomaly detection section. It is validated that proposed Hybrid IDS ensures high detection accuracy (98.68%) and performance at experiment section.

For the property right's protection of the nation, the uncertainty's dissolution and the reliability's security of real estate trade are very important. With the life style's change, the market of real estate becomes diversification, and the level of the real estate trade becomes diversification. But compared with this, the trade system of the real estate has not broken away from the mode in the past yet. To cope with it actively, it needs to review the real estate trade form. Especially, it needs to investigate a plan that can advance the Agency Listing method. The Exclusive Agency Listing and the real estate Information Network System have been the usual system in some advanced countries like America, Japan. It is the system that establishes the real estate brokerage's trade order and encourages the execution for the real estate client's property right's protection and benefit offer. In our country, The Exclusive Agency Listing and the real estate Information Network System were created in the revised real estate brokerage law in 12, 1993. But because of varies of questions, it can not be settled down. So this paper will develop the characteristic factors of the Exclusive Agency Listing and the real estate Information Network System revitalization and examine the mutual relation depends on the factors. And these factors were studied through the proved analysis to the effecting made on the Agency function's consideration and real estate broker' trust and customer satisfaction. So depends on these, the existed value now will present the revitalization plan and political implication about the Exclusive Agency Listing and the real estate Information Network System.

This paper aims to analyze the recent progress(current situation) and tasks of arms control in North and South Korea. To this end the paper is composed of 5 chapters titled instruction; recent progress(current situation) of arms control in South and North Korea; constraints and tasks of arms control on the Korean peninsula; and conclusion. One of the most important tasks for the establishment of a peace structure for the coexistence of the Korean people in the 21st century is the realization of military control in order to resolve the acute military confrontation situation and mutual threats. With the 2018 PyeongChang Winter Olympics, the North-South summit and the subsequent talks for peace and denuclearization on the Korean Peninsula, the North Korea-US summit, and subsequent talks are creating conditions for trust building and arms control between the two Koreas. The military trust between the two Koreas and operational arms control are being achieved through the declaration of the April 27 Panmunjom and the 'Military Agreement for the Implementation of the Panmunjom Declaration.' However, since there are constraints on the control of arms control, such as the persistence of hostility and distrust of the two Koreas, the defense treaty between the two Koreas and neighboring countries, the competition of neighboring countries and the complex interests of the Korean peninsula, Trust Building is important. We should resolve the issue of arms control between the two Koreas, taking into account the trend of international arms control over the internal and external dynamics of the Korean peninsula gradually and carefully, with a vision of long-term unification security.

The purpose of this study is to establish the Police Reform Committee on May 10, 2017, with the aim of enforcing the nationwide autonomous police system in 2020. In addition, the government is promoting reforms of autonomous police and investigative structures, On April 5, 2018, a special committee of autonomous police system consisting of academics, civic groups, and legal professors was established. In 1991, the local council was established in Korea. In 1995, the local autonomous government era was launched with the election of local autonomous governors, but the field of security did not bring decentralization. This study suggests direction of organization and manpower management, personnel management and distribution, financial management, and political neutrality in order to introduce autonomous police system considering regional characteristics. Also, it should be promoted in the direction of maximizing the advantages of the decentralization system and national police without causing civil unrest and social disorder caused by the introduction of the rapid system. Self-governing police should reflect on the trend of autonomous decentralization in order to secure the Republic of Korea with a more secure policing policy, along with organic cooperation and mutual competition system with the national police.

This study investigated a total of 22 types (15 types of natural disasters and seven types of social disasters) of disaster and safety data based on the National Daily Situation Report, Disaster Yearbook and annual Disaster Annals issued by the Ministry of Public Administration and Security. Disaster safety data were collected from the daily situation report of MOIS (Ministry of the Interior and Safety). The number of total data cases were 1,760, of which 656 were natural disasters and 1,104 were social disasters. The disasters were then patternized according to their characteristics. The patterning was conducted to set up the disaster and safety data system designed to keep disaster situations under prompt and effective management. The study analyzed the data associated with the activities in the response and recovery stages according to the disaster type. Furthermore, based on the management activities performed with the flow of time following a disaster, this study classified and proposed disaster and safety data patterns to achieve effective disaster management work by analyzing the characteristics of a disaster and safety data and disaster and safety management procedures. Disasters of high similarity were classified by merging and deleting them. This was done to consider the scalability and mutual linkage so that it can be used in the establishment of national statistical data, such as the disaster annual report and disaster annuity.
