We propose a effectiveness of the assistant pad during cardiopulmonary resuscitation and provide basic data for high quality cardiopulmonary resuscitation. The subjects of the study were 28 students in the emergency department who completed the BLS Health Care-Provider under the experimental study by the randomized crossover design. Data were analyzed by using SPSS 20.0 Version. The results of this study showed that chest compressions using assistant pads decreased pain and fatigue than normal chest compressions, and the depth of chest compressions was deeper than normal depth. The results of this study shows that the use of assistant pads between the one hand and the other hand during cardiopulmonary resuscitation may increase accuracy and depth were improved. Therefore intensive indicator also improved. However, with regard to the use of assistant pads, further studies will be needed to identify the potential for clinical use.

Most people with visual impairments can not use both hands freely because they carry a cane. And unnecessary contact with people around you during walking can occur. Other guides include guide dogs, but the price and maintenance cost are expensive and difficult to manage. In this paper, we propose a smart glove, which prevents unnecessary contact when blind people use the cane, detects the obstacle ahead by using the ultrasonic sensor, and informs the presence of the obstacle by using the servo motor. In addition, the electrostatic proximity touch module on the fingers executes a specific application of the smart phone connected by Bluetooth when the finger touches each other. It is designed to allow you to use text or phone calls when you are lost or in an emergency. The results of this study will be used as a tool to provide a more convenient life for the visually impaired.

Historically, the en-users' acceptance of the expert systems(ES) have generally been used as a proxy for the ES' implementation success by both practitioners and academicians. However, with regard to bank loan decisions, most loan officers approach the acquisition of an ES with apprehension. In order to overcome this skepticism, more research should focus on the behavioral aspects relate to systems acquisition and usage. This research applied Vroom's(1964) expectancy theory in an effort to predict end-users' motivation to use an ES in a bank loan decision context. Because human behaviors and judgements are nonlinear rather than linear functions, accurately predicting human behavior is very difficult. To increase the prediction power for end-users' motivation to use an ES in a bank loan decision context, this research used an artificial neural network (ANN) model. In this research, an attempt was made to evaluate adequacy of the surrogates by analyzing differences between real bank loan officers and student surrogates in applying expectancy theory to estimate bank loan officers' motivation to use ES in a bank loan decision context.

Recently, every student would take lessons without knowing no lecture in campus life. And, If you are a university student, you tired a course to register in a crowded. For solving this problem, we choose the cellular phone. Nowadays peoples have one cellular phone to one person in korea. Using cellular phone, you can use cellular phone anywhere any time. In this paper, we studied mobile synthesis system using mobile cellular phone. According to use mobile campus system, the university and students can use easy an one to one service in ubiquitous.

This study discovers the dynamic nature of an interactional hierarchy as well as an institutional hierarchy in the use of Korean honorifics. Data was collected from the conversations of two Korean female interlocutors. The interlocutors met for the first time in the U.S. and often changed their use of honorifics. The paper examines the method in which the two interlocutors negotiate hierarchies during interaction and how the negotiation is reflected in their use of honorific shifts. The paper also investigates honorific shifts in terms of self-representation to suggest that there is another hierarchy at work other than the institutional hierarchy. An examination of the data shows that the shifts occurred not randomly but strategically. The findings suggest that 1) interlocutors may negotiate interactional hierarchy during their conversation, often in the same sentence, 2) interactional hierarchy often cross the boundary of the institutional hierarchy to obtain interactional goals, in this case, intimacy, and 3) the utterance contents may play a significant role in the interlocutors' honorific shifts.

Zoning data such as national land use planning map, urban land use planning map, agricultural promotion zoning ap, forest land zoning map has a relationship each other in law and spatial context. But difficulties in data share and the lack of accuracy of manual work makes serious inconsistence son zoning data relationship. This causes many trial and error in land use. For resolving this problem the data modellingmethod is presented as a technical solution.

The purpose of this study were to identify the use and related variables of instructional media by middle and high school Home Economics teachers, and to provide the foundations for the use and developments of instructional media by some teachers in Home Economics educational fields. Self administered questionnaires were distributed to middle and high school Home Economics teachers and collected by stamps from Sep. 10 to Sep. 30, 1999, and 138 questionnaires were analysed frequencies, percentages, means, and $\chi$(sup)2-test. The results were as follows：1. Schools in city areas, public schools, and boy’s schools allocated more budget to instructional media for creative Home Economics education. Teachers got instructional media information from colleagues, catalogues from media company, and advertisement or columns of journals or newspapers. 2. More younger teachers with shorter educational experiences and active members in related academic associations owned more instructional media and had the ability to develop various instructional media. 3. Most teachers showed dissatisfaction to the prices, purchasing processes, information, quality, and assortments of instructional media.

A certificate is important media for the purpose of offering user-authentication service on PKI system. In the paper we analyzed management implement which could make the efficient use of a certificate. This implement called ClientCA will make efficient use of the service about user-authentication consisting of the basis in the age of information through efficient management and partial use of each certificates. Especially, ClientCA could be used efficiently by grafting a small group of PKI system which is operated with particular purposes.

According to the common use of digital images, the need of image editing software is being increased rapidly. In this paper, we surveyed and summed up general users about their use style, favorite menus, troublesome functions about their image editing software. It was examined that about 73 % of the users thought that image editing software were more difficult than other applications thanks to the superfluous menu and function structure. We designed and proposed a new structure of menus and functions for general users to learn easily and make efficient use of an image editor.

Internet has begun various transformation and innovation in terms of society, culture and industry. Today, Social Network Service(SNS) is an exceedingly popular and useful tool for making human relationships. Previous studies related to SNS, which based on Technology Acceptance Model(TAM), were focused on user acceptance of new technology. However, they had the limitations to focus on technology acceptance, without the consideration of the cognitive factors in using SNS. This study examined how the main factors of intention to use of SNS continuously affect perceived usefulness and ease of use through familiarity, self-expression, hedonic shopping value, utilitarian shopping value and personal relationship. The results of hypothesis testing showed that familiarity, self-expression, hedonic shopping value and personal relationship have some positive impacts on the perceived usefulness and ease of use. The practical contribution of this study is to suggest useful decision alternatives concerned to marketing strategies for acquiring and retaining long-term customers related to SNS business.
