A studio type urban lifestyle housing was recently introduced as a new urban multi-housing typology. It was particularly created to meet the increasing housing demand of one-person households due to the population change and the shortage of housing supply. However, some concerns have been raised, because the government's policy has been focused on expanding housing supply by easing certain legal regulations in construction. Poorly planned and managed urban lifestyle housings might degrade living conditions for one-person households and ultimately harm urban environments. As such, this research is conducted to investigate the design characteristics of the studio type urban lifestyle housing from selected construction precedents in Seoul. Critical evaluations are made for the facilities and uses in site plans, unit plans, and shared public spaces. As a result, problem areas are found in the lack of design varieties, privacy protection in units, control of natural environment conditions, and the absence of community spaces. Improvement strategies can be suggested by comparing with some overseas' housing precedents: Design variations can be extended through flexible structure, facility, and furniture systems. Privacy and natural environment can be controled through the integration of interior space configurations and exterior envelope systems. The housing policy needs to be reconsidered to improve a variety in design, residents' social interaction, security, and management. Thereby, the studio type urban lifestyle housing should be holistically approached in terms of design and policy to enrich urban living experiences by residents and communities.

A goal of this research is to propose the remodeling possibility from deteriorated stock apartment housing, to three generation family living in a dwelling unit for low incomes. An apartment housing which was built from 1970s, is accumulated over $55\%$ of the stock housing in Korea, many of them are confront with a rebuilding in a short usage of twenty years below. They are small one, and many of the residence complain narrow and small space compare to economic growth and their needs. This article deals the reform of two to one dwelling units, that it can be use for three generation family living as a new residence, because its spatial character is more controled privacy condition as a four bay spatial organization in the dwelling. The reform simulated in a 10, 13, 14, 15, and 16 pyung, the remodeling size became from 20 to 30 pyung, and its reform can be apply to extend life cycle of a stock confront with redevelopment. The possibility of the reform houses have more intensive privacy in a house compare with same area of new apartment. It tells us that we can recycle the deteriorate apartment house into three generation family living use, and it will be clue to change slum clearance into reform and recycle of deteriorate apartment house.

GUMF (Global User Management Framework) that is proposed in this research can be applied to next generation network such as BcN (Broadband convergence Network), it is QoS guaranteed security framework for user that can solve present Internet's security vulnerability. GUMF offers anonymity for user of service and use the user's real-name or ID for management of service and it is technology that can realize secure QoS. GUMF needs management framework, UMS (User Management System), VNC (Virtual Network Controller) etc. UMS consists of root UMS in country dimension and Local UMS in each site dimension. VNC is network security equipment including VPN, QoS and security functions etc., and it achieves the QoSS (Quality of Security Service) and CLS(Communication Level Switching) functions. GUMF can offer safety in bandwidth consumption attacks such as worm propagation and DoS/DDoS, IP spoofing attack, and current most attack such as abusing of private information because it can offer the different QoS guaranteed network according to user's grades. User's grades are divided by 4 levels from Level 0 to Level 3, and user's security service level is decided according to level of the private information. Level 3 users that offer bio-information can receive secure network service that privacy is guaranteed. Therefore, GUMF that is proposed in this research can offer profit model to ISP and NSP, and can be utilized by strategy for secure u-Korea realization.

The digital forensic analysis ensures the integrity of confiscated data by calculating hash values for seizure and search of digital evidence and receiving confirmation and signature from participants. However, evidence that is irrelevant to the alleged offense needs to be deleted even after seizure from the point of view of privacy. But the hash value is altered by deleting the irrelevant data from the image file, one will not be able to prove that the file is in the initial state when it was seized. Therefore, in this paper, a study was conducted to support the integrity of the digital evidence, even if some of the seized digital evidence was deleted or damaged during the seizure search. The hash value of each data is calculated and hash value of the combination of hash values are also calculated. Even if the unrelated evidence is deleted from the seized evidence regardless of file system such as FAT or NTFS, the suggested method presented a way to provide the integrity that proves there is no change in the evidence file.

The rapid growth of data has successfully promoted the development of modern information and communication technologies, which are used to process data generated by public urban departments and citizens in modern cities. In specific application areas where the ciphertext of messages generated by different users' needs to be transmitted, the concept of broadcast encryption is important. It can not only improve the transmission efficiency but also reduce the cost. However, the existing schemes cannot entirely ensure the privacy of receivers and dynamically adjust the user authorization. To mitigate these deficiencies, we propose an efficient, secure identity-based broadcast encryption scheme that achieves direct revocation and receiver anonymity, along with the analysis of smart grid solutions. Moreover, we constructed a security model to ensure wireless data transmission under cloud computing and internet of things integrated devices. The achieved results reveal that the proposed scheme is semantically secure in the random oracle model. The performance of the proposed scheme is evaluated through theoretical analysis and numerical experiments.
