Public library legislation is the essential means of providing for all the citizen in modern society with a standard public library service. We can trace the origin of that back to the Public Libraries Act 1850 in England. This paper is reviewing all the measures concerning public libraries of England since then in order to find out some guidelines for revision of the Korean Library Law enacted in 1963. Although Public Libraries Act 1850 was an output of a series of social reform movement in the 19th century, it established first the provision of public library service su n.0, pported by public funds. However the Act had several restrictions hindering public library service from making progress. These are: 1. Adoptive legislation in nature 2. Limitation of the size of population and rate income 3. Small library authorities 4. Procedure for adoption by public meeting 5. Restrictions on the ways in which rate income might be spent 6. No governmental organization to direct or control for a standardized public library service 7. No cooperative schemes among libraries. Subsequent development was directed largely to removal of those limitations. The present Public Libraries Act 1964 as a model of public library legislation was enacted on the basis of such reports as Kenyon, McColvin, Roberts, and Bourdillon. All but the problem of small library authorities were removed with this new Act. The final object could be achieved by the Local Government Act 1974 which reorganized existing 383 small authorities into new 115 ones the average population of which was 280, 000. Now, McColvin's dream of 30 years could be fulfilled in the late 70's. He argued that the minimum size of population of a viable authority should be 300, 000. Although the effect of the 1964 Act on the development of public library services in England was great, there must be some considerations as to the provisions of public library objective, government funding for library services, free use of library materials to all regardless of residence, and placement of library committee within the authority.

The post-corona era is having a major impact on university campus life, and campus cultural life has undergone drastic changes. In the process of adapting to this change. The existing face-to-face learning method is converted to non-face-to-face learning, and kiosks representing campus self-service are increasingly used. Subsequently, in order to match the characteristics of public places such as university campuses and provide better self-service, there are no related studies considering UI design elements of kiosks and characteristics of kiosks. This study conducted a survey on Chinese university students considering the characteristics and usability of university campus kiosks through user interface design elements in terms of design by considering previous studies. The purpose of this study is to examine the relationship between color, icon, typography, which are elements of kiosk interface design, and convenience, reliability, and usability, which are characteristics of a kiosk. In this study, the design elements and characteristics of the unmanned self-service system kiosk UI used by students at four universities in Korea and China were set as the scope of the study, and related documents were organized and surveyed in Korea and China. Case analysis and comparison method Through the kiosk usage characteristics of 4 universities were derived. The usability evaluation criteria use the five evaluation criteria suggested by the authority JacobNidsn. The usability evaluation criteria use the five evaluation criteria suggested by the authority JacobNidsn.

The iCAS specification that download CAS s/w image from the IPTV provider's server to the IPTV devices provides compatibility and service mobility between the IPTV service providers. However, to ensure mobility of the device, a TA(Trust Authority) within an IPTV eco-system that is capable of systematically managing keys or certificates is required. In the Legacy CAS, solution providers for CAS play a critical role of carrying out the TA. However, in order to standardize the device mobility, a TA should be established by implementing iCAS technology that manages the entire IPTV eco-system including iCAS. In this paper, we analysis TA issues related iCAS commercialization, and propose TA establishment strategy for IPTV service in iCAS environment.

Cloud computing offers a platform that is both adaptable and scalable, making it ideal for outsourcing data for sharing. Various organizations outsource their data on cloud storage servers for availing management and sharing services. When the organizations outsource the data, they lose direct control on the data. This raises the privacy and security concerns. Cryptographic encryption methods can secure the data from the intruders as well as cloud service providers. Data owners may also specify access control policies such that only the users, who satisfy the policies, can access the data. Attribute based access control techniques are more suitable for the cloud environment as they cover large number of users coming from various domains. Multi-authority attribute-based encryption (MA-ABE) technique is one of the propitious attribute based access control technique, which allows data owner to enforce access policies on encrypted data. The main aim of this paper is to comprehensively survey various state-of-the-art MA-ABE schemes to explore different features such as attribute and key management techniques, access policy structure and its expressiveness, revocation of access rights, policy updating techniques, privacy preservation techniques, fast decryption and computation outsourcing, proxy re-encryption etc. Moreover, the paper presents feature-wise comparison of all the pertinent schemes in the field. Finally, some research challenges and directions are summarized that need to be addressed in near future.

The execution of a construction project involves the engagement of many participants. Generally, the Authority uses CM to certify that the Work is built according to the contract documents. The CM work scope is expressed in the Construction Technology Management Act and its Regulation. The mandated and delegated CM services are limited to the construction period. If Contractor is required to repair a construction defect, the Contractor should bear the burden of the inspection service for the defect repair, because it is associated with him. Nevertheless, CM should submit a bond to provide the inspection and supervision service for the defect repair. These may result in conflict with each liability. Therefore, CM service in the law and regulation was investigated and analyzed in this study to classify the characteristics of CM contracts, and it was suggested that the CM liability for the inspection and supervision service for the defect repair should be reconsidered.
