The purposes of this study are to define 'housing welfare' which constitutes an important theme of discussion today and to present some future policy issues. Recently, the expression 'housing welfare' is widely used in our daily life and written in some laws, but its concept is still ambiguous. Housing welfare can be defined as 'the situation in which citizens gain access to a decent housing and adapt themselves well to the community life. In this context, the goals of housing welfare policy should be as follows: reduction of the number of households living below the minimum standard in housing, promotion of the right to housing, housing provision and management based on housing needs, linkage of housing and other welfare measures, realization of social integration and social justice. But, there are still some controversies on such questions as target group, moral hazard of beneficiaries, social equity, etc. To get all the policy alternatives more effective, efforts should be made to improve the general infrastructure of welfare policies, to prevent NIMBY phenomenon of local actors, and so on.

This study discusses the direction of legislation to strengthen the legal protection of medical records privacy in information age. The legislation trends on privacy protection of medical records in European Union and United States are analysed and the current law and regulation of Korea on medical records are compared. The issues discussed include the ownership of medical records, the patient's right of access to medical records, medical information publication for other than treatment or insurance processing use, confidentiality responsibility of provider organizations, medical information management in provider organizations, penalty for the unlawful use of patient information. This study concludes that the patients' right on medical record and provider organization's responsibility in processing patient information should be strengthened in order to protect patients' privacy and to conform to the international standard on medical record protection in the information age.

One type of network security breach is the availability breach, which deprives legitimate users of their right to access services. The Denial of Service (DoS) attack is one way to have this breach, whereas using the Intrusion Detection System (IDS) is the trending way to detect a DoS attack. However, building IDS has two challenges: reducing the false alert and picking up the right dataset to train the IDS model. The survey concluded, in the end, that using a real dataset such as MAWILab or some tools like ID2T that give the researcher the ability to create a custom dataset may enhance the IDS model to handle the network threats, including DoS attacks. In addition to minimizing the rate of the false alert.

As natural language processing technology using machine learning develops, a Smart Home Network Service (SHNS) is drawing attention again. However, it is difficult to apply a standardized authentication scheme for SHNS because of the diversity of components and the variability of users. Blockchain is proposed for data authentication in a distributed environment. But there is a limit to applying it to SHNS due to the computational overhead required when implementing a proof-of-work system. In this paper, a lightweight work proof system is proposed. The proposed lightweight proof-of-work system is proposed to manage block generation by controlling the work authority of the device. In addition, this paper proposes an access control scheme for SHNS.

Version control is an application to maintain consistency between different instances of the same document allowing operations such as navigation, differencing, and merging. Most version control systems, however, lack the support of functionality for cooperative writing environment, such as to represent and store the history of the actions of different individuals, to effectively differentiate and merge the individual actions including the text object, and to manage different access privileges for different granularity and individuals. With the help of Activity IDentification (AID) tag and its unique addressing scheme proposed in this paper, differencing and merging become simple and effective. Access and role control is improved by associating the access right table and role assignment in AID scheme also eliminates the requirements for large storage capacity for version information maintenance.

The Internet technologies allows anybody who has connect a network to access various multimedia information. But, it brings new issues about the violation of intellectual property and copyright of multimedia contents. Digital right managements have been actively studied as approaches to solve them. In this paper, we propose license-based schemes for the protection of contents and its rights on digital right management. The proposed schemes provide limited distribution and superdistribution of contents, and guarantee to securely use contents by usage rules.

In recent years, Personal Health Record (PHR) has emerged as a patient-centric model of health information exchange. The Personal Health Record (PHR) owners enjoy the full right of accessing their records anywhere and anytime making storage and retrieval more efficient. Due to the sensitivity and confidential nature of the PHR, however, the PHR is maintained in a secure and private environment with the individual determining rights of access. In this paper, we propose a system which enables access to the user's PHR in the event of emergency. In emergency situation where the user is unconscious, the emergency staff can use the PHR information to request a emergency access to the PHR server based on the predefined rights of access for PHR. Under the proposed system, the PHR owner can specify a fine grain access control policy during emergency situations.

To ensure data confidentiality and fine-grained access control in business environment, system model using KP-ABE(Key Policy-Attribute Based Encryption) and PRE(Proxy Re-Encryption) has been proposed recently. However, in previous study, data confidentiality has been effected by decryption right concentrated on cloud server. Also, Yu's work does not consider a access privilege management, so existing work become dangerous to collusion attack between malicious user and cloud server. To resolve this problem, we propose secure system model against collusion attack through dividing data file into header which is sent to privilege manager group and body which is sent to cloud server and prevent modification attack for proxy re-encryption key using d Secret Sharing, We construct protocol model in medical environment.

Applying the gyroscopic technology, HeadZmouse has been developed to simulate left and right mouse click, double click, drag and drop, and even a wheel function for navigating web. This device was designed to work on both PC and Macintosh environments using a USB cable. The first time you use this device, you'll find out how much freedom it offers to someone who can't use his or her hands freely. Rather than being tied to your computer, simple manipulation such as blowing an air (breathing) into a sonic sensor can simulate all the functions which standard mouse has, even including a wheel function. Also, a macro-interface device has been developed. By storing repetitive tasks into a memory, you can carry out repetitive tasks just by clicking a button once.
