The domestic libraries offered users computer environment early to adapt in information age. However, the computer environment is generalized today, so it is needed to change about the role of electronic information room in this point. The author investigated use experience by 78 students who are student in library and information science. They experienced electronic information room and wrote their experience. As a result, they felt most inconvenience in information service of librarians, facilities and equipment and space. To improve the service of electronic information room, it is needed to develop the mission and service policy of electronic information room. And also the librarian must think the room as modern reference room that has digital and analog materials and information technology.

As the varification of public library services has been come true through the increase of multimedia information accompanied with the development of information tachnology and the advent of various electronic materials the repetitive and labo intensive process has been cut down by the development of network system. Recentrly the electronic library using outside networks electronic library facilities at the time of their new contructions. In this study it is aimed that the outline of the library planning is presented with the case analyses of domestic and foreign libraries especially concerning the kinds and features of the required spaces for electronic libraries their scale basic facilities. The conclusions of this study are : First the spaces requred for electronic library are as mentioned below: catalgue are equipped with terminal information service center reference room electronic reading room computer training center and conference room. Second computer room for management and electronic information center has been made recently in the Library of Seoul City. The space for librarians room is to be 5.48$m^2$ per person on average and for electronic information center of library provided with an exclusive use is to be 5.1$m^2$ per person.

In this paper, we developed the computer room environments and infrastructure management systems to operate various networking devices and the infrastructure in the room, stably. The developed systems are composed of the computer room environment management system and the computing infrastructure management system. The computer room environment management system performs the role which the temperature and humidity detection node periodically detects the temperature and humidity and transmits the information to the remote intelligent server. The computing infrastructure management system enables the computer room's manager to check the information and maintenance history of the computing devices with a smart device supporting NFC(Near Field Communication).

In this paper, we propose an electronic attendance management system using the bluetooth function of the beacon and BLE advertising function of the smart phone. In the beacon-only bluetooth attendance confirmation system, it is needed more than one beacons according to the class room sizes. A BLE advertising function based attendance confirmation system can not provide the information about the location of the attendances. In the proposed system, we can identify the location of the instructor using the beacon of the class room, and confirm the attendances by checking the position of the attendances's smart phone. In this system, we can achieves the goals of electronic attendance management system using only one beacon per a class room.

Purpose: The purpose of this study was to explore the effectiveness of informational intervention delivered by electronic patient information board in the OR waiting room for reduction of anxiety of mothers with child having operation. Method: Nonequivalent control group non-synchronized design was used in this study. The subjects was 52 mothers whose children underwent elective surgery in one Pediatric Hospital. Informational intervention in this study consisted of four critical stages. State anxiety by Spielberger, mean arterial pressure, and heart rates at preoperative and postoperative period were measured. The data were analyzed by using Chi-Square test and t-test with SPSS/PC 10.0 program. Results: 1) There was a significant difference in the state anxiety between the control and the experimental groups. 2) There was no significant difference in the mean arterial pressure between the two groups. 3) There was no significant difference in the heart rate between the two groups. Conclusion: The results of this study indicate that informational intervention delivered by electronic patient information board would be an effective intervention during the operation in reducing anxiety of mothers with child having operation.

This study aims to provide architectural basis of the new space planning in university library and anticipate direction in future. This study is to analyze the spatial transition in the existing facility, based on field observation of the domestic university library and on theoretical data from the related article. The result that include a transition of the existing facility and the present is as following as below. 1) Spatial transitions by networking are making specific system room. The minimum area of this specific system room is 33.95$m^2$. 2) Spatial transition by information service is forming computer room. the minimum area of a environmental carrel, which is possibly located to computer room, is 2.98~3.42$m^2$. 3) Spatial transition by spreading multimedia information is to make the multimedia information is to make the multimedia room. It is necessary to independent, flexibility, and extensionable space. 4) Library interior spatial transition by developing information technology is prospected that in case of reading room, office enlarge the scale, in case of stack decrease the scale. The university library must be kept up their function and also be functioned as electronic library which serve new information.

PZT thin films were formed by rf-magnetron sputtering on $Pt/Ti/SiO_2/Si$ substrate. Bulk PZT target containing $5\%$ excess PbO was used. They were formed with in-situ process at $650^{\circ}C$ as total thickness of 175 and 250 nm after the depositing of thin PZT films at room temperature, i. e. 2-step Sputtering. It was found that the ferroelectric perovskite phase is formed at $650^{\circ}C$ by XRD and the interface between room temp.-layer and $650^{\circ}C$ -layer is not existent. In the samples undergoing 2-step sputtering the dielectric constant was 600 or more and the leakage current density was $2{\times}10^{-7}A/cm^2$. So, we found that the room temp.-layer on the bottom electrode stabilize the underlaid layers.

Porous copper bromide (CuBr) films are highly advantageous for detecting ammonia (NH₃). The fabrication of porous CuBr films requires complex high-temperature processes or multistep processes. Herein, we report the uncomplicated preparation of porous CuBr films by a spin-coating method and the films' excellent NH₃ sensing properties. The porous films were prepared by spin-coating 100, 150, and 200 mM CuBr solutions, and then dried in a vacuum oven for 2 h. All the films showed a high NH₃ response; in particular, the film prepared using a 100 mM CuBr solution showed an extremely high response (resistance ratio = 852) to 5 ppm NH₃. The film also showed fast response and recovery times, 272 s and 10 s respectively, even at room temperature. The outstanding NH₃ sensing characteristics were explained in relation to the porosity and thickness of the prepared films. The high-performance NH₃ sensors used in this study can be used for both indoor air quality and environmental monitoring applications.
