The arbitration procedure, which is a private trial, does not have a separate enforcement agency. Therefore, unless a party consents to the arbitration award and voluntarily fulfills the award, its execution is accomplished through the implementation of the national court. In particular, the decision in the foreign arbitration procedure will be refused or rejected for the arbitration award in case the proceedings of the law and procedure on which the judgment is based are caused by inconsistency with the domestic law or procedural defect. However, all foreign arbitration awards generally do not have to go through the approval process, and it will come into force with the arbitration award. In the case of Germany in the revision of the German Civil Procedure Act of 1996, the main provisions of the New York Convention concerning the ratification and enforcement of arbitration proceedings are reflected. Germany provides for the arbitration procedures in the arbitration proceedings of Book 10 of the Civil Procedure Act. Particularly, with Article 1061 in Book 10 Section 8 below, the approval and enforcement of foreign arbitrators shall be governed. Article 1061 has been referred to as "The New York Convention on the Recognition and Enforcement of Foreign Jurisdictions," Article 5 (1). The main reasons for approval and enforcement rejection are: (1) Reason for the acceptance or refusal of enforcement by request of the parties: Reason for failure of subjective arbitration ability, invalidation of arbitration agreement, collapse of attack or defense method, dispute not included in arbitration agreement, (2) Reasons for the approval and enforcement of arbitration considered by the competent authority of the arbitrator: violation of objective arbitration ability, violation of public order, but not based on the default of German statute.

Many computer security systems use the signatures of well-known attacks to respond to hackers. For these systems, it is very important to get the accurate signatures of new attacks as soon as possible. For this reason, honeypots and honeypot farms have been actively researched. However, they can only collect a small amount of information because hackers have a strong tendency to directly attack servers of which IP addresses are allocated. In this paper, we propose an unused ports-based decoy system to redirect hackers toward honeypots. This system opens unused ports to lure hackers. All interactions with the unused ports are considered as suspect, because the ports aren't those for real service. Accordingly, every request sent to the unused ports is redirected to a honeypot. Consequently, this system enables honeypots to collect information about hackers attacking real servers other than themselves.

The PP-1/64-128 block cipher support variety data block and secret key size. Also, it is suitable for hardware implementation and can much easier to apply Concurrent Error Detection(CED) for cryptographic chips compared to other block ciphers, because it has same encryption and decryption process. In this paper, we proposed truncated differential cryptanalysis of PP-1/64-128. the attack on PP-1/64-128 block cipher requires $2^{50.16}$ chosen plaintexts, $2^{46.16}$ bytes memory spaces and $2^{50.45}$ PP-1/64-128 encryption to retrieve secret key. This is the best result of currently known PP-1/64-128 differential cryptanalysis.

Vulnerable web applications have been the primary method used by the attackers to spread their malware to a large number of victims. Such attacks commonly make use of malicious links to remotely execute a rather advanced malicious code. The attackers often deploy malwares that utilizes unknown vulnerabilities so-called "zero-day vulnerabilities." The existing computer vaccines are mostly signature-based and thus are effective only against known attack patterns, but not capable of detecting zero-days attacks. To mitigate such limitations of the current solutions, there have been a numerous works that takes a behavior-based approach to improve detection against unknown malwares. However, behavior-based solutions arbitrarily introduced a several limitations that made them unsuitable for real-life situations. This paper proposes an advanced web browser based malicious behavior detection system that solves the problems and limitations of the previous approaches.

Hash based RFID protocols proposed by Ha and M.Burmester is a scheme that tag's ID is updated using hash function to provide forward secrecy after session end. But this protocols have a problem both privacy and efficiency. This paper analyze a problem for privacy to apply a privacy game model proposed by Vaudenay. we analyze the cause that these scheme is difficult with tag's cheap implementation and efficient resynchronization. To solve these problems, we proposed a new hash based mutual authentication protocol which apply only two protocol's advantages. this protocols is based of resynchronization algorithm for Ha et al.'s protocol and added a new simple counter to record the numner of continuous desynchronization between tag and reader secret informations. this counter is more simple than cyclic counter proposed by M. Burmester's protocol. Also, we prove that proposal protocol improve a privacy against a privacy attack which is executed for Ha and M. Burmester's protocols.

Since the 9·11 terror attack in 2001, the Maritime Logistics Security System has been strengthened and required X-ray image for every imported cargos from manufacturing countries to United States. For scanning cargos, the container inspection systems use high energy X-rays for examination of contents of a container to check the nuclear, explosive, dangerous and illegal materials. Nowadays, the X-ray cargo scanners are established and used by global technologies for inspection of suspected cargos in the customs agency but these technologies have not been localized and developed sufficiently. In this paper, we propose the X-ray array detector system which is a core component of the container scanning system. For implementation of X-ray array detector, the analog and digital signal processing units are fabricated with integrated hardware, FPGA logics and GUI software for real-time X-ray images. The implemented system is superior in terms of resolution and power consumption compared to the existing products currently used in ports.

Due to the rapid progress in network technology, many research on content security technologies is also being conducted in the mobile digital content sector. In the meantime, content protection has been immersed in preventing illegal copying, certifying, and issuance/management certificates, but still have many vulnerabilities in managing or authenticating confidential information. This study aims to strengthen confidential information about content based on dual management of content download rights through mobile phone numbers or device numbers. It also protect replay-attack by building a secure mobile DRM system where digital content is safely distributed based on a three-stage user authentication process. In addition, blockchain-based content security enhancements were studied during the primary/secondary process for user authentication for the prevention of piracy and copyright protection. In addition, the client authentication process was further improved through three final stages of authorization in the use of illegal content, considering that legitimate users redistributed their content to third-party.

Kwon presented the aviation medical examination regulations related to COVID-19 announced by the Ministry of Land, Infrastructure, and Transport of the Republic of Korea. Lim summarized various efforts of airlines to overcome the crisis in the aviation industry. He also discussed the management of these aircraft as the number of airplanes landing for long periods increased. Finally, he suggested various quarantine guidelines at airports and onboard aircraft. COVID-19 has had a profound impact on mental health as well as physical effects. Kim investigated the impact of COVID-19 on mental health and suggested ways to manage the stress caused by it. The Internet of Things (IoT) refers to a technology in which devices communicate with each other through wired or wireless communication. Hyun explained the current state of the technology of the IoT and how it could be used, especially in the aviation field. In the area of airline service, various situations arise between passengers and crew. Therefore, role-playing is useful in performing education to prepare and respond to passengers' different needs appropriately. Ra introduced the conceptual background and general concepts of role-playing and presented the actual role-play's preparation process, implementation, evaluation, and feedback process. For a fighter to fly for a long time and perform a rapid air attack, air refueling is essential, which serves refueling from the air rather than from the aircraft base. Koo developed a questionnaire based on the HFACS (Human Factors Analysis and Classification System) model and used it to conduct a fighter pilot survey and analyze the results.

According to the recent change in the cybersecurity paradigm, research on anomaly detection methods using machine learning and deep learning techniques, which are AI implementation technologies, is increasing. In this study, a comparative study on data preprocessing techniques that can improve the anomaly detection performance of a GRU (Gated Recurrent Unit) neural network-based intrusion detection model using NGIDS-DS (Next Generation IDS Dataset), an open dataset, was conducted. In addition, in order to solve the class imbalance problem according to the ratio of normal data and attack data, the detection performance according to the oversampling ratio was compared and analyzed using the oversampling technique applied with DCGAN (Deep Convolutional Generative Adversarial Networks). As a result of the experiment, the method preprocessed using the Doc2Vec algorithm for system call feature and process execution path feature showed good performance, and in the case of oversampling performance, when DCGAN was used, improved detection performance was shown.

Drag reduction is significant research in aircraft design due to its effect on the cost of operation and carbon footprint reduction. Aircraft currently use conventional solid winglets to reduce the induced drag, adding extra structural weight. Fluidic on-demand winglets can effectively reduce drag for low-speed flight regimes without adding any extra weight. These utilize the spanwise airflow from the wingtips using hydraulic actuators to create jets that negate tip vortices. This study develops a computational model to investigate fluidic on-demand winglets. The well-validated computational model is applied to investigate the effect of injection velocity and angle on the aerodynamic coefficients of a rectangular wing. Further, the turbulence parameters such as turbulent kinetic energy (TKE) and turbulent dissipation rate are studied in detail at various velocity injections and at an angle of 30°. The results show that the increase in injection velocity shifted the vortex core away from the wing tip and the increase in injection angle shifted the vortex core in the vertical direction. Further, it was found that a 30° injection is efficient among all injection velocities and highly efficient at a velocity ratio of 3. This technology can be adopted in any aircraft, effectively working at various angles of attack. The culmination of this study is that the implementation of fluidic winglets leads to a significant reduction in drag at low speeds for low aspect ratio wings.
