The purpose of this study was to investigate factors influencing role adaptation in newly employed nurses and the consistency between role expectations before employment and after one year of employment. The results of this study may contribute to strategy development towards positive role adaptation in newly employed nurses. The data used in this study were collected from 111 nurses, the sample was drawn from all newly employed professional nurses working at Y Medical Center in 1987. The data were collected longitudinally in the 2nd - 3rd weeks, the 3rd month and the 12th month after employment. The results of this study were as follows : 1. The degree of change the importance of factors influencing role adaptation and the length of time after employment were investigated. the result showed that the degree of change was the greatest within the first 3 months after employment. Important factors related to role adaptation were working conditions, the environment of the assigned ward and the work load. These factors always displayed high scores without any great change over time. New employees put more importance on practical factors which were obtained through experience in their jobs rather than on ideal factors Which they had considered more important while in school. 2. Consistency between role expectation before employment and after 12 month of employment was investigated. The highest consintency item was the expectation about the variety of Patients, and the highest inconsistency was the expectation about their own welfare. An average score of 69.07 points was achieved from a maximum of 125 points for the 25 items. showing that expectations for role development before employment were not fully satisfied. In conclusion the administraor should assess the initial expectation at the time of employment of new nurses and she / he should make clear to the new nurses that these expectations may not be realistic. In this way the administrator can provide more satisfactory conditions towards the expectations of the new nurses and help them towards positive role adaptation and reduction of role conflict. Newly employed nurses have high and unrealistic expectations about socialization to the profession from their nursing educational program. It is suggested that a transitional training program should be planned and carried out for newly employed nurses.

Virtual environment is an interactive multimedia space that allows users to experience realistic sensory feedbacks and interactions as they do in real world. There have been some work on the development of two-dimensional user interface for supporting interactions in a virtual environment. However, most of them were designed for specific virtual environments and hence could not be easily deployed to other virtual worlds. To address this problem, some frameworks were developed for building two-dimensional user interfaces for virtual environment, but they had limitations in usability or flexibility. In this paper, we present the HIVE framework, which is designed to help ease the development of two-dimensional user interface for the virtual environment while satisfying the requirements of both usability and flexibility. The HIVE framework utilizes XML and scripting capability, dynamic module loading, XML and script language for usability. It provides module reading, configuration, and event processing mechanism for flexibility. This paper first explains the HIVE framework and describes the applications developed for some virtual environments followed by discussing the future research directions.

The study aims to reveal the factors that impact the decisions made by child care directors in the process of managing their day care centers. The seven participants I surveyed are directors in child care centers located in Seoul and Kyung Ki-Do. Through in-depth interviews and case-by-case studies, I uncovered that there are both external and internal factors that influence a director decisions. The external factors are following the standards set by the law, accommodating the demands set by parents, collaboration with the teachers, accepting the advice of friends and family, and creating realistic conditions. The internal factors are each director's own management philosophy, religious beliefs, and personal experience. This study aims to create policies for establishing and developing educational material so that child care directors will be able to provide an ideal environment for the supervision and education of children.

To meet the increasing demand from various fishing fields for training of fishing equipment operators, a fishing winch simulator was designed to train maritime students in the correct and safe operation of hydraulic winches under various load conditions related to fishing operations. The aim of this study is to describe the basic dynamic characteristics of the newly developed hydraulic fishing winch simulator and particularly to analyze the mechanical responses produced on the winch operation controls. The winch simulator consists of two winch units, a computer control and data acquisition system, a control consol and other associated mechanisms. When one winch is in hauling mode, the other one will always be in loading mode. The revolution speed of the hauling winch was controlled by a proportional directional control valve, and the braking torque of the loading winch was controlled by a proportional pressure control valve. The simulation experiments indicated that the dynamic characteristics of the hauling winch followed the braking response characteristics of the loading winch. The tests also showed that the warp speed and tension linearly depend on the pressure differential across the motor of the loading winch controlled by operating the proportional pressure control valve during the hauling operation. The experience gained from various training courses showed that the fishing winch simulator was very realistic and it was valuable for training novice winch operators. The results of the winch simulation exercise were recorded and used to evaluate the training on the operation and handling of the winch system. From these test results, we concluded that the tension acting on the warp during hauling operations can successfully be simulated by controlling the pressure differential across the motor with step changes of the control input signal to the proportional pressure control valve of the loading winch.

With the growing demand for multimedia services and advances in display technology, new applications for 3$\sim$D scene communication have emerged. While multi-view video of these emerging applications may provide users with more realistic scene experience, drastic increase in the bandwidth is a major problem to solve. In this paper, we propose a fast prediction mode decision algorithm which can significantly reduce complexity and time consumption of the encoding process. This is based on the object segmentation, which can effectively identify the fast moving foreground object. As the foreground object with fast motion is more likely to be encoded in the view directional prediction mode, we can properly limit the motion compensated coding for a case in point. As a result, time savings of the proposed algorithm was up to average 45% without much loss in the quality of the image sequence.

A three-dimensional image capturing device and its signal processing algorithm and apparatus are presented. Three dimensional information is one of emerging differentiators that provides consumers with more realistic and immersive experiences in user interface, game, 3D-virtual reality, and 3D display. It has the depth information of a scene together with conventional color image so that full-information of real life that human eyes experience can be captured, recorded and reproduced. 20 Mega-Hertz-switching high speed image shutter device for 3D image capturing and its application to system prototype are presented[1,2]. For 3D image capturing, the system utilizes Time-of-Flight (TOF) principle by means of 20MHz high-speed micro-optical image modulator, so called 'optical resonator'. The high speed image modulation is obtained using the electro-optic operation of the multi-layer stacked structure having diffractive mirrors and optical resonance cavity which maximizes the magnitude of optical modulation[3,4]. The optical resonator is specially designed and fabricated realizing low resistance-capacitance cell structures having small RC-time constant. The optical shutter is positioned in front of a standard high resolution CMOS image sensor and modulates the IR image reflected from the object to capture a depth image (Figure 1). Suggested novel optical resonator enables capturing of a full HD depth image with depth accuracy of mm-scale, which is the largest depth image resolution among the-state-of-the-arts, which have been limited up to VGA. The 3D camera prototype realizes color/depth concurrent sensing optical architecture to capture 14Mp color and full HD depth images, simultaneously (Figure 2,3). The resulting high definition color/depth image and its capturing device have crucial impact on 3D business eco-system in IT industry especially as 3D image sensing means in the fields of 3D camera, gesture recognition, user interface, and 3D display. This paper presents MEMS-based optical resonator design, fabrication, 3D camera system prototype and signal processing algorithms.
