  • Purpose: This study aimed to derive the elements for effectively improving the management of emerging infectious diseases in the emergency room in large general hospitals. Methods: This research involved an analytic hierarchy process analysis of 10 experienced nurses working in a large general hospital located in the Seoul metropolitan area. The weighted values of the criteria for evaluating the importance of the management elements of patients with emerging infectious diseases in the emergency room of large general hospitals were derived using an analytic hierarchy process survey. Results: The results of the analytic hierarchy process analysis showed that experts considers responsiveness (0.291) as most important with respect to the criteria for the policy for isolation and control of infectious patients. The order of importance of the criteria for the policy for isolation and control of infectious patients were as follows: responsiveness (0.291), economical efficiency (0.257), feasibility (0.242), and sustainability (0.209). Subsequently, the weighted values of the management of the policy elements were determined based on the derived importance of the criteria mentioned above. These were, in order of priority, the construction of communication channels with the government authorities when dealing with emerging infectious diseases (15.9%), the equipment and provision of personal protective equipment to protect nurses from infection and dissemination of material (14.6%), and the operation of the isolation room and patient separation systems (14.1%). Conclusion: This study suggests critical strategies for infection control during a pandemic of emerging infectious disease.

  • Purpose: This study was to examine the effects of supportive nursing care on surgical patients in the operating room. Method: This study was nonequivalent control group none-synchronized design. The data were collected during the period of July 26 through October 8, 1999 at K hospital in Kwangju. The subjects for the study were selected from those patients who were admitted to K hospital for abdominal surgery. Forty-eight adult subjects were selected and evenly divided into two groups: 24 for the experimental group and the other 24 for the control group, respectively. The tool used for measuring state and trait anxiety was the one originally worked out by Spilberger(1976), and translated by Kim Jung- Taek and Shin Dong-Kyun(1978) for suitable application for Koreans. Data were analyzed by $\chi^2$- test, t-test, Chronbach's ${\alpha}$ coefficient using SAS/PC+. Result: Results were as follows : 1. The degree of State anxiety was found to be lower in the experimental group who received supportive nursing care in the operating room immediately before an operation than the control group who did not."(p<.001). 2. There was no significant difference on the post-test blood pressure and pulse rate immediately before operation between the two groups(p>.05). Conclusion: Results of the above study reveals that the supportive nursing care in the operating room is effective in alleviating the anxiety of patients. I suggest that it is highly desirable to apply supportive nursing care for those patients who are waiting for immediate surgery.

  • The purpose of this study is to minimize radiation exposure to the workers and public members during CT examination. The objects are seven of the CT rooms in university hospitals and four of the CT rooms in clinics located in Busan and Gyung-nam area. The places of measurement for radiation leakage are 1) 3 m above the ground of shielding wall in the control room 2) particular space in the control room 3) worker's gate in the control room 4) the patient gate. Its values were calculated maximum leakage radiation per week(MLRW). As a result, the worker's gate of M clinic displayed the highest dose. When it was calculated by MLRW in classic method, it showed 1) $5.97{\pm}0.23$, 2) $0.50{\pm}0.02$, 3) $10.00{\pm}0.11$, 4) $2.37{\pm}0.47$ mR/week. All of them did not exceed limit for maximum permissible dose per week(MPDW). However, When MLRW of M clinic was calculated by empirical method, its value displayed $118.31{\pm}17.72$ mR/week.(MPDW>100 mR/week). Radiation leakage influenced in the control room(p<0.05). Therefore, The way of calculating MLRW must be developed and shielding wall in control room is designed 3 m above the ground for reducing dangerous of leakage radiation.

  • If we can supply accurate minute flow rate to the households, we can solve many problems that are occurring in consequences of uncontrolled flow rate for the households. Therefore, this paper presents an innovative solution to the source of the problems by illustrating how we can control the flow rate to the household. This paper proves such problems even can be solved in a case when there is a room turned off the heating.

  • Recently, scientists introduced a new type of microscope capable of investigating nonconducting surfaces in an atomic scale, which is called AFM (Atomic Force Microscope). It was an innovative attempt to overcome the limitation of STM (Scanning Tunnelling Microscope) which has been able to obtain the image of conducting surfaces. Surfaces of samples are imaged with atomic resolution. The AFM is an imaging tool or a profiler with unprecedented 3-D resolution for various surface types. The AFM technology, however, leaves a lot of room for improvement due to its delicate and fragile probing mechanism. One of the room for improvements is gap control between probe tip and sample surface. Distance between probe tip and sample surface must be kept in below one Angtrom in order to measure the sample surface in Angstrom resolution. In this paper, AFM system modeling, experimental system identification and control scheme based on system identification are performed and finally sample surface is measured by home-built AFM with such a control scheme.

  • In this study, noise arresting effect of the noise control room from the transmission of surrounding noise was tested when the packing noise control rooms were set up in the test room in which the prerecorded noise from an engine room was reradiated at the same level as the original pressure. The inner space of control room A is $3.389m^3(1.19\times1.19\times2.14m)$ having walls furnished with plywood board 9mm in thickness and noise control room door$(60\times45cm) $ and illumination lamp are placed. In case of the control room B, noise absorption board(10mm fiber board which holds the corntype concavity with diameter of 5mm, depth 5mm, space 15mm) is adhered to the internal ceiling and styrol foam boards(20mm) to the walls. The other struction is same as the control room A. Type C is the same as B except wool board(Glass Fiber, 33mm) on the walls. Type D is same as type A except that the thickness of wall is 12mm and wood pyramid type cone$(5\times5\times13cm)$ is adhered to the ceiling ana walls(Fig. 1). When the recorded noise and vibrated noise were controlled in various levels. The noise pressure which passed through the control rooms was measured by sound level meter(Bruel & Kjar 2205, measuring range 37-140dB). In order to calculate the absorption rate in the control rooms the noise pressure was measured at different distances when the recorded noise pressure was radiated. The followings are the results obtained from the experiment. 1. When the noise pressure of the test room was 60dB, transmission rate of type A was $69.7\%$ and increased $3.3\%$ per 10dB. At the same condition, the rate was $53.9\%$ and increased $4.5\%$ per 10dB in type D. Type D was the most effective in noise arresting of the four and the effect was D,C,B and A in order(Fig.2). 2. When the oscillator sound and vessels noise were radiated in 1,000Hz, at one meter distance to the type A and D, the oscillator sound pressure were 77dB and 73dB, while the vessels noise pressure were 73.3dB and 66.2dB respectivley(Fig.3). 3. Refering to the influence of the frequency to the lower oscillator sound(1,000Hz) pressure, both type C and D were almost same at 140cm but type C was 0.3dB lower than type D at 20cm distance(Fig.4).

  • The case study for this research is a middle school music room located in Iksan City, Korea. Although the room is used for teaching music, indiscreet sound-absorbing materials were applied within the space. Accordingly, a number of difficulties have been experienced when using the room. During a music lesson, the sound-volume is inadequate for music appreciation, while the music performance has an arid sound due to an insufficient echo. In order to control the obstructive factors resulting from a short Reverberation Time, the acoustic factor is optimized in this study by using an Acoustic Simulation, following an arrangement of Acoustic Design. A Psycho-acoustics Experiment was conducted using the Auralizational Technique, whereby the Virtual Acoustic Field can be experienced at the design stage.

  • This paper describes a mirror control system that can adjust the location of side and room mirror of the vehicle automatically using 3D coordinates to monitor the location of driver's eyes. Through analysis of the image inputted by two B/W CCD camera and infrared lamps installed on top of the driver's dashboard, we can estimate the values of 3D coordinate of the driver's eyes. Using these values, this system can determine the absolute position of each mirror and activate each actuator to the appropriate position. The stereo vision system can detect the driver's eyes whether it is day or night by virtue of infrared Lamps. We have tested this system using 10 drivers who drive a car currently, and most of the drivers were satisfied with the convenience of this system.
