The purpose of this thesis is to do a research on suppression of peacetime international terrorism and penal system of terrorists by political and economic means. International terrorism means wanton killing, hostage taking, hijacking, extortion or torture committed or threatened to be comitted against the innocent civilian in peacetime for political motives or purposes provided that international element is involved therein. This research is limited to international terrorism of political purposes in peacetime, especially, hijacking of civil aircraft. Hijacking of civil aircraft include most of international terrorism element in its criminal act and is considered to be typical of international terrorism in view of multinationality of its crews, passengers and transnational borders involved in aircraft hijacking. Civil air transportation of today is a indispensable part of international substructure, as it help connect continuously social cultural and economic network of world community by dealing with massive and swift transportation of passengers and all kinds of goods. Current frequent hijacking of civil aircraft downgrade the safety and trust of air travel by mass slaughter of passengers and massdestruction of goods and endanger indispensable substructure of world community. Considering these facts, aircraft hijacking of today poses the most serious threat and impact on world community. Therefore, among other thing, legal, political, diplomatic and economic sanctions should be imposed on aircraft hijacking. To pursue an effective research on this thesis aircraft hijacking by six Chineses on 5th May, 1983, from mainland China to Seoul, Korea, is chosen as main theme and the Republic of Korea's legal, political and diplomatic dealing and settlement of this hijacking incident along with six hijackers is reviewed to find out legal, political diplomatic means of suppression and solution of international terrorism. Research is focused on Chinese aircraft hijacking, Korea-China diplomatic negotiation, Korea's legal diplomatic handling and settlement of Tak Chang In, mastermind of aircraft hijacking and responses and position of three countries, Korea, China and Taiwan to this case is thoroughly analyzed through reviewing such materials as news reportings and comments of local and international mass media, Korea-China Memorandum, statements of governments of Korea, China and Taiwan, verdicts of courts of Korea, prosecution papers and oral argument by the defendants and lawyers and three antiaircraft hijacking conventions of Hague, Tokyo and Montreal and all the other instruments of international treaties necessary for the research. By using above-mentioned first-hand meterials as yardsticks, legal and political character of Chinese aircraft hijacking is analyzed and reviewed and close cooperation among sovereign states based on spirit of solidarity and strict observance of international treaties such as Hague, Tokyo and Montreal Conventions is suggested as a solution and suppressive means of international terrorism. The most important and indispensable factor in combating terrorism is, not to speak, the decisive and constant resolution and all-out effort of every country and close cooperation among sovereign states based on "international law of cooperation."

Emergencies and disasters can happen any time without any warning, and things can change and escalate very quickly, and often it is swift and decisive actions that make all the difference. It is a responsibility of the building facility management to ensure that a proven evacuation plan in place to cover various worst scenario to handled automatically inside the facility. To mapping out optimal safe escape routes is a straightforward undertaking, but does not necessarily guarantee residents the highest level of protection. The emergency evacuation navigation approach is a state-of-the-art that designed to evacuate human livings during an emergencies based on real-time decisions using live sensory data with pre-defined optimum path finding algorithm. The poor decision on causalities and guidance may apparently end the evacuation process and cannot then be remedied. This paper propose a cloud connected emergency evacuation system model to react dynamically to changes in the environment in emergency for safest emergency evacuation using IoT based emergency exit sign system. In the previous researches shows that the performance of optimal routing algorithms for evacuation purposes are more sensitive to the initial distribution of evacuees, the occupancy levels, and the type and level of emergency situations. The heuristic-based evacuees routing algorithms have a problem with the choice of certain parameters which causes evacuation process in real-time. Therefore, this paper proposes an evacuee routing algorithm that optimizes evacuation by making using high computational power of cloud servers. The proposed algorithm is evaluated via a cloud-based simulator with different "simulated casualties" are then re-routed using a Dijkstra's algorithm to obtain new safe emergency evacuation paths against guiding evacuees with a predetermined routing algorithm for them to emergency exits. The performance of proposed approach can be iterated as long as corrective action is still possible and give safe evacuation paths and dynamically configure the emergency exit signs to react for real-time instantaneous safe evacuation guidance.

The Kepler mission has shown that small planets are extremely common. It is likely that nearly every star in the sky hosts at least one rocky planet. We just need to look hard enough-but this requires vast amounts of telescope time. MINERVA (MINiature Exoplanet Radial Velocity Array) is a dedicated exoplanet observatory with the primary goal of discovering rocky, Earth-like planets orbiting in the habitable zone of bright, nearby stars. The MINERVA team is a collaboration among UNSW Australia, Harvard-Smithsonian Center for Astrophysics, Penn State University, University of Montana, and the California Institute of Technology. The four-telescope MINERVA array will be sited at the F.L. Whipple Observatory on Mt Hopkins in Arizona, USA. Full science operations will begin in mid-2015 with all four telescopes and a stabilised spectrograph capable of high-precision Doppler velocity measurements. We will observe ~100 of the nearest, brightest, Sun-like stars every night for at least five years. Detailed simulations of the target list and survey strategy lead us to expect $15{\pm}4$ new low-mass planets.

The purpose of this thesis is to examine the effects of e-CRM activities by the internet shopping mall companies on the purchase activities of purchase customers and the potential customers. The internet shopping companies utilize e-CRM to systematically identify customers' varying demands, and to utilize the results as marketing tools, thus producing a significant effect on the potential customers by generating customer feedback through e-Community. Contrary to their intention, however, cognitive dissonance can occur through e-Community, which may lead to customers' complaints. If these complaints are not properly managed and settled in a timely manner, they can be transferred to other potential customers, and the conformity phenomenon could be created by other complaining customers. Findings obtained through this thesis are as follows: If cognitive disharmony is created by customers who purchased products through the internet shopping malls, this can lead to private complaining behaviors, and subsequently, these behaviors are formed through e-Community. If the internet shopping mall companies do not take any timely and proper measures to intervene in the stage of private complaining behaviors in the first place, these behaviors will immediately escalate into the public complaining behaviors. Furthermore, the complaints will be transferred to other potential customers, ultimately resulting in their swift expansion. In other words, contrary to intention of the internet shopping mall companies, e-CRM does not facilitate the potential customers purchase decision, it rather affects them to postpone or withdraw their purchase decision. Accordingly, the internet shopping mall companies are required to manage e-Community with extreme care, and they should promptly respond to the complaining customers so that e-Community can function properly.

China has been developing a new auto industry growth plan since 2004. In line with this initiative, China actively adopted its policy favoring foreign companies' investment which had a competitive edge over their technologies and manufacturing methodologies. To meet this demand in policy and market change, many foreign auto companies and their parts' manufacturers including Korean auto companies joined this stream. Policy change favoring higher technologies applicable in China requested auto companies' swift adaptation to meet the policy requirements by higher technologies with innovation and introduction of those foreign technologies to China. The spatial (excellence) strategy was followed by the increase in its efficiency and competiveness of each region, which were materialized by or in the form of; Firstly, strategic partnership with China auto companies and encouragement of Korea auto parts manufacturing companies to set up its own factories in China. Secondly, modularization and platform sharing strategy by applying enhanced technologies. Thirdly, strategic utilization of China local government's incentive policies. As production management methodology, JIS was adopted all across the board to meet the on-demand market requirements in the manufacturing processes. Auto part manufacturers had been integrated regionally based on forward linkages and modules. As a result, regional-specific auto industry complexes have been made in the places such as Beijing-Hyundai in the north, Dongfeng-Yueda-Kia in the south, common auto parts at central area like Qingdao, and other parts and raw materials in the vicinity of Shanghai.

As of June 2008, the government's expansion policy for the long-term care service infrastructure has achieved an outstanding 96.4% occupancy rate of facilities across the country. Despite such achievement, practical issues including the physical lack of facilities, disproportional regional spread and decline in government accountability have raised concerns about the effectiveness of the policy's implementation. This study was aimed at defining the implementation procedure of expansion policy for long-term care service infrastructure, analyzing variables that affect it, examining the problems revealed in implementation procedure, and suggesting improved plan on that policy. Research methods were to review literatures on infrastructure expansion policy, to conduct case studies on K province, C city and 4(2 corporations and 2 privately owned) facilities in C city for studying practical implementation procedure on a local government level, and to use Alexander(1985)'s framework for analyzing variables of policy implementation. As a result of this study, policy variables including the clarity and adequacy of policy goal, nature of service providers, task and responsibility between government authorities, and implementation variables such as propensity toward budget allocation, financial restraint, swift utilization of budgets and the streamlining of involved procedures and inter-agency relations stood out as the main factors affecting policy implementation. In adddition, this study suggested several improvement measures such as accounting facilities need based on real local demand and supporting to private participation and so on.

The Altai Humanities Belt connecting Siberia to Central Asia is very important to the history of civilization. It had a huge influence on the formation of an ancient civilization in the Korean Peninsula. Therefore, a variety of studies have been carried out in the field of folklore and anthropology as well as archeology. One of these studies is about the oral epic. The oral epic remains in the form of a unique transmission in Korea, but it wasn't that long ago when it was noted as the component of the Altai Humanities Belt. In that context, some epics from Central Asia, Mongolia, and Siberia were introduced to Korea. This preliminary investigation is conducted to introduce the oral epic Olonkho from Yakutia in Siberia to Korean academia. Although it was revealed recently, Olonkho is highly valued. The epic study has been buried from the Western point of view, but Olonkho is expected to provide a global perspective to the field of epic study. Above all, it contains a very significant clue to a new study because the content and the style of performance are considerably different from those of the West. Additionally, the original form is relatively well preserved. In particular, it explains how human thinking and behaviors have changed in the transition from the mythical age to the heroic age. This change appears in the ethnic history of Yakutia, as well as in the formation process for all Altai countries around the 10th century. Therefore, this preliminary investigation will be a foundation to facilitate the translation of the voluminous Olonkho into Korean, and to conduct full-fledged research on it. In particular, it can motivate a study on the differences and similarities in comparison to the tradition of oral epics between Central Asia and the Korean Peninsula. Furthermore, it will serve as a foundation for the formation of the Altai Humanities Belt.

Although the rapid development of technology has led to a swift increase in the number of companies using social networking services (SNS), it will not be accurate to say that they have fully "utilized" the functionality of SNS simply by "using" these services. Therefore, this study aims to increase the convenience of using digital technology and help SNS users in extending the functionality of these services beyond their regular use and thus, revitalize the field by increasing the service providers' efficiency. In this study, the Facebook usage status of a graduate school newspaper from an undisclosed university in Seoul was analyzed from February to December, 2021 using the participant observation method. The results of the study revealed the following: First, it is necessary to diversify the subject and type of content to ensure a continuous supply of quality content; Second, there is a need to examine the user categories and characteristics by utilizing SNS functionalities such as, the target reports and insights, and based on this, supply content that meets the needs of the users; Third, to resolve the problem of low levels of user participation and an inactive Facebook account, it is necessary to mobilize new marketing tools like online events. The significance of this study is that it confronts the real problems faced by some companies that cannot keep pace with market changes in a digital environment, identifies failure factors, and proposes solutions to them.
