In an attempt to study the current status and ways to revitalize cultural programs in small libraries, this study surveyed 142 small libraries based in the Seoul. Two most important functions of both public and private small libraries were found to be the loan/return of materials and cultural programs; over 50% of small libraries are operating cultural programs. It was also found that institutions that did not operate the cultural programs were aware of the necessity. Both public and private small libraries were operating one to three cultural programs, and their types varied from cultural refinement to reading-related programs. There was a higher rate of answers stating that the person in charge of operating cultural programs for public small libraries were administrative personnels, while the chief librarian was the person in charge for private small libraries. The hardships both types of libraries encountered were found to be budget-related and on securing manpower.

Libraries are founded to ensure the intellectual freedom of citizens, and citizens have the right to confidentiality regarding their needs, information access, and information use. Protecting users' privacy is critical to safeguarding their freedom of speech, freedom of thought, and freedom of assembly. Libraries and librarians should seriously concern themselves with their users' privacy because protecting this privacy is part of their most important mission, and, in doing so, users can truly enjoy their intellectual freedom. This study extensively investigated and analyzed the possibility of privacy invasion that may occur in libraries. As a result, cases of potential invasion of privacy in libraries were summarized in the following three categories: violations occurring in the process of national or law agencies' enforcement operations; violations occurring in the process of routine library services such as circulation, reference, online searching etc.; and violations occurring by outsourcing library services.

Ubiquitous computing technology provides anytime and anywhere accessibility to information, ubiquitous computing is adapted in the various field to increase efficiency of work. After looking into the trend of ubiquitous computing, case studies of information service using mobile service and RFID system in library were investigated in this paper. Library information service are providing retrieval of library OPAC and verifications of circulation and return date using mobile internet technology. In addition, various notice services using short me sage service(SMS) of mobile are available. Considering growing mobile service and RFID system advancement of related technology, more information service utilizing mobile service and RFID system should be developed in near future.

Quality system of construction industry in Korea was a means to prevent unqualified construction work. But lately, it has became an essential requirement. So, lots of construction companies acquire ISO quality management system which provides fundamental management criteria. Now, most of the Korean construction companies have got IS0 quality management system. So, getting ISO quality management system doesn't mean advantage in public competition of construction bidding and that causes increase in the maintenance cost. That's why some construction companies abandon the 150 certificate. Therefore, the authors need to check the effect of ISO quality management system. For this, the authors provide the performance measurement index of ISO quality management system.

RFID ( Radio Frequency IDentification ) is an automatic realization technology that recognizes things or a person with data stored tag, card, label, etc that have microchip by using radio frequency. Automation and efficient data base management(DBM) of system are possible by replaces using Bar-code that is used widely with using RFID. In this paper, we designed RFID tag data format that used to recognize information of books in Library and implemented library management system. Library management system is divided checking collection of books, self-loaning books system, self-returning books system, management books information system for a librarian. RFID leader realized information of tag and transfer it to host computer through RS-232 interface. Host computer processes and operates information with middleware. System that we made is depending on executive system for a librarian.

This paper is an embedded system using the X-Hyper Intel PXA255 ARM CPU that base of the Linux operation system. This system applies tag information reading through RFID leader to Library executive system and designed and embody RFID middleware. The RFID middleware is consisted of RFID module, ARM processor and RS-232 interface. The RFID module is used to be inputted user and books information and RS-232 interface pass information by RFID middleware. Also, This system is embodied by specific Library management system using embedded exclusive use ARM processor. In this paper introduces concept and action principle of RFID middleware and uses Qt/Embedded and embodied manless loaning and return system.

In this paper, we designed a dynamic TDMA scheme for smooth tactical data distribution in TDMA tactical datalinks. Since the existing tactical datalinks use fixed time radio resources, it is impossible to change the resource status according to network conditions during operation. To overcome these limitations, we designed, implemented, and simulated the DTDMA processing and related messages such as initial timeslot allocation, intermediate time slot allocation, time slot return, and timeslot retrieval. As a result, it was shown that the method of effectively allocating and using timeslot resources according to the situation is applicable. Therefore, we will continue research to manage DTDMA communication on tactical data link in the future.

This paper presents an UHF(Ultra High Frequency) band small cavity structured RFID(Radio Frequency Identification) tag antenna with a long reading range, designed to apply on metal cart or pallet for auto-parts logistics. The size of tag antennas is $140{\times}60{\times}10mm^3$, attached on a exporting metal cart, and it can give the information of inventory and logistics of carts. By collecting the exported carts and increasing the recovery rate of missing carts or pallets, the paid import tax can be refunded when the carts are returned back to the manufacture. The tag antenna was equipped with a cover to prevent damage, and the dielectric constant of the cover is considered for the simulation. The reading range of the tag antenna is 12 m using LP(Linear Polarization), 10 m with CP(Circular Polarization) reader antennas. This 920 MHz UHF RFID cavity tag ensures the long reading distance of the antenna regardless of the material of the object where it is attached.

In astronomy, the amount of data generated using wide-field optical telescope has increased exponentially. However, the fixed-size small-scale computing environment and the complexity of data analysis tools, results in difficulties to process the massive observation data collected. To resolve this problem, we propose a cloud-based automation system for the efficient processing of the enormous data gathered. The proposed system consists of a Workflow Execution Manager which manages various workflow templates and controls the execution of workflows instantiated from theses templates, and an Elastic Resource Manager that dynamically adds/deletes computing resources, according to the amount of data analysis requests. To show the effectiveness of our proposed system, we exhaustively explored a board spectrum of experiments, like elastic resources allocation, system load, etc. Finally, we describe the best practice case of DEEP-SOUTH scheduling system as an example application.

The purpose of this study is to ascertain librarian's perceptions on their users' library access and its patterns. Interviews with seven library staff reveal physical accessibility issues including spatial relationships between libraries and other facilities such as shopping malls and schools, travel distance, transportation mode, and temporal perspectives of library access. The results from the interviews corroborate the findings from secondary analysis using household travel data. However, interviewees do not have a clear picture of how much their users travel and spend to access their libraries. This is true, even though these factors are critical to analyze physical accessibility. Based on the findings, this study makes recommendations to improve the accessibility of public libraries. Suggestions include the concept of sponsorships with other facilities, the placing of material drop-boxes on the main route, and providing library programs during lunch time.
