Scholars are paying increasingly close attention to brain research and the creation of biological neural networks, artificial neural networks, artificial intelligence, neurochips, brain-computer interfaces, prostheses, new research instruments and methods, methods of treatment, as well as the prevention of neurodegenerative diseases based on these data. The authors of the study propose their hypothesis on the understanding of the phenomenon of consciousness that answers questions concerning the criteria of consciousness, its localization, and principles of operation. In the study of the hard problem of consciousness, the philosophical and scientific categories of consciousness, and prominent hypotheses and theories of consciousness, the authors distinguish "the area of the conscious mind", which encompasses several states of consciousness united by the phenomenon of integrated consciousness. According to the authors, consciousness is a kind of executor of the phenomenological idea of the "chalice", so the search for it should be conducted deeper than the processes in the power of thought consciousness and transconsciousness, to which integrated consciousness can act as a lever. However, integrated consciousness may have the capacity to transcend into lower states of consciousness, which requires further study.

As it seems like critical information leakages have been increasing due to industrial espionage and malicious internal users, the importance of introducing audit and log security technology is growing every now and then. In this paper, we suggest the session logging system for the company's internal control to meet the SOX legislation level, by monitoring and analyzing users behaviors connecting to the business-critical Operating System. The system proposed in this paper aims to monitor the user's illegal activities in the Operating System, and to present the clear evidence of purpose of those activities by detailed logs. For this purpose, we modified Operating System by adding multiple services suggested in this paper. These services utilize interfaces provided by the existing Operating System and add functions to control access and get logs. The system saves and manages session logs of users or administrators connected to the server with centralized log storage. And the system supports session log searching and lookup features required by SOX legislation for the company's internal controls with the level of computer forensics and logging technology.

As intellectual terror threats increase, we feel the limit in coping with those threats and the things we do are placing traditional X-ray machines & ETD and increasing aviation security staffs. In fact, even if air transportation system is the fast and most efficient transportation methods, it is true that there are many inconveniences to endure due to terror threats. In the name of security, even if we make a lot of efforts and time to screen both good-natured passengers, baggage, cargo and suspicious passengers, it is impossible to screen perfectly and it is not an efficient methods. Therefore, we introduce profiling system that reduce the effort to screen good-natured passengers but focus on screening dangerous passengers and baggages. Profiling system strengthens aviation security, using the concept "Selection & Concentration". Israel started to introduce manual profiling system in aviation security, which is interviewing suspicious passengers and it has been used in crime investigation since 1960. And it has been upgraded and diversified to CAPPS(Computer Assisted Passenger Screening Program) and SPOT(Screening Passenger by Observation). So, this theses is to study on the concept & kind of profiling and profiling methods adopted in airlines. Also it presents the method of introduction of profiling system in Korea and the necessity of making law on it.

In this era of changing system, we may learn lesson from newly developed Uniform Electronic Transation Act(UETA) in 1999. Korea has its counterpart as the Basic Electronic Transaction Act and Electronic Signature Act made by 1999. While UETA stresses on transaction law between individuals, that of Korean stresses on the role of government in electronic transaction. Both laws have the common definitions as electronic record, electronic signature, however, UETA has its own definitions such as automated transaction, computer program, electronic agent, information, information processing system, and security procedure. Especially, transferable record in section 16 is one of the most unique concept which Korean law does not provide. Korean government is planning to introduce electronic note in the near future, which will make unprecedented reform in Korean financial industry. Since Korean law does not have such a concept as electronic note, revision of the law is expected soon. Korean law has its specialty which puts stress on cyber mall, authentication agency, and consumer protection. In U.S., the interpretation of law by court is important when they have disputes according to common law traditon. Studies on cases on disputes in U.S. is needed most for Korean application.

To implement crowdsensing system in reality, trustiness between service provider server and user is necessary. Service provider server could manipulate the evaluation of sensing data to reduce incentive. Moreover, user could send a fake sensing data to get unjust incentive. In this paper, we adopt private blockchain on crowdsensing system, and thus paid incentives and sent data are unmodifiablely recorded. It makes server and users act as watcher of each others. Through adopting smart contract, our system automates sensing data evaluation and opens to users how it works. Finally, we show the feasibility of proposing system with performance evaluation and comparison with other systems.

Private specialized institutions differ from public ones in that they mostly act independently. This paper reports a study designed to assess the provision of specialized institutions for children with intellectual disabilities in Saudi Arabia. The approach taken in this study was qualitative, involving a case study strategy that enabled the researcher to gain rich and in-depth information based on the shared experiences of participants comprising institution leaders, educators and families from two specific specialized settings, one public and one private. The study aimed to examine the existing disparities in service delivery so as to develop a clear picture of the service quality provided by public specialized institutions for children with intellectual disabilities in Saudi Arabia. The results suggest that the weak relationship with inpatient and specialized institutions is a consequence of the parents' poor responsiveness, which may result in these institutes developing a negative impression of the parents. Conversely, the lack of active initiative on the part of the public specialized institutions led to a negative parental attitude towards these institutions. A sensible approach to resolving this problem might be to recognize that these institutions have a significant responsibility to encourage parents of children with intellectual disabilities to become involved in their children's learning, to promote positive attitudes.

The destructive impact of contagious diseases outbreaks on all life facets necessitates developing effective solutions to control these diseases outbreaks. This research proposes an end-to-end, data-driven platform which consists of multiple modules that are working in harmony to achieve a concrete goal: early detection of contagious diseases outbreaks (i.e., epidemic diseases detection). Achieving that goal enables decision makers and people in power to act promptly, resulting in robust prevention management of contagious diseases. It must be clear that the goal of this proposed platform is not to predict or forecast the spread of contagious diseases, rather, its goal is to promptly detect contagious diseases outbreaks as they happen. The front end of the proposed platform is a web-based dashboard that visualizes diseases outbreaks in real-time on a real map. These outbreaks are detected via another component of the platform which utilizes data mining techniques and algorithms on gathered datasets. Those gathered datasets are managed by yet another component. Specifically, a mobile application will be the main source of data to the platform. Being a vital component of the platform, the datasets are managed by a DBMS that is specifically tailored for this platform. Preliminary results are presented to showcase the performance of a prototype of the proposed platform.

A novel, chaotic map that is based on concatenated torus automorphisms is proposed in this paper. As we know, cat map, which is based on torus automorphism, is highly chaotic and is often used to encrypt information. But cat map is periodic, which decreases the security of the cryptosystem. In this paper, we propose a novel chaotic map that concatenates several torus automorphisms. The concatenated mechanism provides stronger chaos and larger key space for the cryptosystem. It is proven that the period of the concatenated torus automorphisms is the total sum of each one's period. By this means, the period of the novel automorphism is increased extremely. Based on the novel, concatenated torus automorphisms, two application schemes in image encryption are proposed, i.e., 2D and 3D concatenated chaotic maps. In these schemes, both the scrambling matrices and the iteration numbers act as secret keys. Security analysis shows that the proposed, concatenated, chaotic maps have strong chaos and they are very sensitive to the secret keys. By means of concatenating several torus automorphisms, the key space of the proposed cryptosystem can be expanded to $2^{135}$. The diffusion function in the proposed scheme changes the gray values of the transferred pixels, which makes the periodicity of the concatenated torus automorphisms disappeared. Therefore, the proposed cryptosystem has high security and they can resist the brute-force attacks and the differential attacks efficiently. The diffusing speed of the proposed scheme is higher, and the computational complexity is lower, compared with the existing methods.

Korean police have been established as a national police system since the liberation of Korea and have been operated as a centralized police system for a long time, and a police committee was established under the enactment of the Police Act in 1991. However, the National Police Commission has a problem that it cannot perform the functions of the original National Police Commission because it is only a simple advisory body, not an institution that reviews and decides major policies related to police administration. As a result, despite the passage of a full amendment to the Police Act in 2020 and the revision of the Act to the Organization and Operation of the National Police and Local Police, operational and compositional problems still exist. Therefore, this study intends to propose the current state of operation and problems of the police committee system and measures for improvement.
