The purpose of this study is to investigate the nurses' needs in the general hospitals as a basic study to develop ICU clinical nurse from Aug. 3 to Sept. 26 1998 at 13 general or university hospitals that have ICU nurse training course and are accredited at KNA. The subjects of study were ICU nurses and nurse managers at the department of nursing. The questionnaire items were developed from literature review, interviews with 30 ICU nurses at an university hospital in Pusan. The results were as follows : The subjects of study educated in ICU nurse training course were 44.3% of total. The 93.1% responded the necessity of ICU CNS and 89.1% wanted to have ICU CNS certification. The 43.8% answered that ICU should be a center of CNS education and 32.0% answered the department of nursing. Most of subjects responded that the clinical experience of ICU should be needed prior to CNS education. Regarding the treatment of ICU CNS, the 34.2% of total subjects responded it would be suitable to pay additional allowance and the 28.3% answered to grade-up salary step, and then the 13.7% to promote level position. Concerning the assignment department, the 63.5% answered that the charge nurse would be proper than general nurse or head nurse. As to the working time of ICU CNS, the 93.2% responded that D-duty is needed, the 79.5% to E-duty and the 64.4% to N-duty. It is suggested that the consensus of ICU nurses for the concept, the role and the system of ICU CNS is needed.

Purpose: The purpose of this study was to investigate the degree of information technology application, and to identify the effect of information technology application en knowledge management process in clinical nurses. Method: Participants were 629 regular clinical nurses who had worked for over 1 year in general units of 9 tertiary medical hospitals including 2 national university hospitals, 5 university hospitals, and 2 hospitals founded by business enterprises. Data were collected from March to May 2003 through questionnaires. Thee structured instruments were used to collect the data: Information Technology Application scale, Knowledge Management Process Scale(Jeong, Lee, Lee, & Kim, 2003), and one for general characteristics. The data were analyzed using reliability analysis, descriptive analysis, one-way ANOVA, $Scheff{\acute{e}$ test, correlation analysis, partial correlation analysis, and multiple regression analysis with the SPSS for Windows 10,0 program. Result: 1) The HIS application degree, IT application ability, and IT application frequency were significantly correlated with the degree of knowledge management process activation and 4 elements of knowledge management process, Knowledge Creation, Knowledge Storage, Knowledge Sharing, and Knowledge Utilization(p=.000). 2) The 3 variables, HIS application degree, IT application ability, and IT application frequency explained 47.2% of the total variance of the degree of knowledge management process activation, and 352% of me total variance of Knowledge Storage. And 2 variables, HIS application degree and IT application frequency explained 17.6% of the total variance of Knowledge Creation, 39.9% of the total variance of Knowledge sharing, and 33.8% of the total variance of Knowledge utilization(p=.000). 3) As a result of multiple regression analysis, the key determinant of the degree of knowledge management process activation for nurses was HIS application degree The HIS application degree, IT application frequency, position, IT application ability, and continuous total numbers of years working at the present hospital explained 51.1% of the total variance of the degree of knowledge management process activation(p=.000). Conclusions: These results suggest that the information technology application positively affects the nurses' knowledge management process. From the above findings, information technology application is empirically verified as a useful and effective method to activate knowledge management process, and knowledge management.

The purpose of this study was designed to find out the effectiveness of vertebral segment instability, muscle fatigue response on lumbar spine after apply lumbosacral stabilization exercise program to 4 patients with chronic low back pain and for 12 weeks. In this study, the lumbar spine motion with blind by MedX test machine and the difference of instability to lumbar vertebra segments in flexion, extension test of standing position and spinal load test(Matthiass Test) by Spinal Mouse. The stabilization exercise program was applied 2 times a week for 12 weeks in hospital and 2 times a day for 20 minutes at home. The results of the present study were as follows: 1. Instability test of lumbar vertebra segment is 2 type differential angle test between vertebrae segment and loading test of spine(matthiass) by Spinal Mouse. It appeared to improve stability of segments in sagittal plane after applying program. So lumbar spine curve increased lordosis toward anterior and was improved of the lumbar spine flexibility in flexion and extension. Specially, in matthiass test, (-) value was increased between lumbar vertebra segment when was the load on spine. And so applying stability improved after program. 2. Fatigue response test(FRT) results, in male, was raised muscle fatigue rate during increase weight, on the other hand female appeared lower than male. As a results, lumbosacral stabilization exercise was aided to improvement of lumbar spine vertebra segments stabilization. Spine instability patients will have a risk when in lifting a load or working with slight flexion posture during the daily of living life and it is probably to increase recurrence rate. Thus, not only lumbar extension muscle strength but also stability of vertebra segments in lumbar spine may be very important.

Purpose: Stress distribution and mandible distortion during lateral movements are known to be closely linked to bruxism, dental implant placement, and temporomandibular joint disorder. The present study was performed to determine stress distribution and distortion patterns of the mandible during lateral movements in Class I, II, and III relationships. Methods: Five Korean volunteers (one normal, two Class II, and two Class III occlusion cases) were selected. Finite element (FE) modeling was performed using information from cone-beam computed tomographic (CBCT) scans of the subjects' skulls, scanned images of dental casts, and incisor movement captured by an optical motion-capture system. Results: In the Class I and II cases, maximum stress load occurred at the condyle of the balancing side, but, in the Class III cases, the maximum stress was loaded on the condyle of the working side. Maximum distortion was observed on the menton at the midline in every case, regardless of loading force. The distortion was greatest in Class III cases and smallest in Class II cases. Conclusions: The stress distribution along and accompanying distortion of a mandible seems to be affected by the anteroposterior position of the mandible. Additionally, 3-D modeling of the craniofacial skeleton using CBCT and an optical laser scanner and reproduction of mandibular movement by way of the optical motion-capture technique used in this study are reliable techniques for investigating the masticatory system.

The syndrome of carotid sinus hypersensitivity is cardovascular symptom complex including lightheadedness, transient loss of consciousness, perspiration, pallor, weakness of lower extremities, transient hypotension, bradycardia and seizure, which occurs from firing of hyperactive carotid sinus reflex. Most cases are idiopathic, but maliganant tumors involving parapharyngeal space have been occasionally implicated. We present a case of carotid sinus hypersensitivity due to nasopharyngeal carcinoma invading the parapharyngeal space with bilateral cervical lymphnode metastases(stage IV, $T_4N_2M_0$). The patient experienced several episodes of severe syncope proceeded by blurring of vision, dizziness and nausea, which were used to occur while he was working in erect position. The tumors were markedly regressed by external radiation therapy with successful resolution of syncope.

MPEG-I is actively working on standardization on the immersive video coding which provides up to 6 degree of freedom (6DoF) in terms of viewpoint. In a virtual space of 3DoF+, which is defined as an extension of 360 with motion parallax, looking at the scene from another viewpoint (another position in space) requires rendering an additional viewpoint using multiple videos included in the 3DoF+ video. In the MPEG-I Visual workgroup, efficient coding methods for 3DoF+ video are being studied, and they released Test Model for Immersive Video (TMIV) recently. This paper presents a patch packing method which packs the patches into atlases efficiently for improving coding efficiency of 3DoF+ video in TMIV. The proposed method improves the reconstructed view quality with reduced coding artifacts by introducing guardbands between patches in the atlas.

Personal exposure relies on characteristics of time activity patterns of the population of concern as human activities impact the timing, location, and level of personal exposure. The information about time spent in microenvironments plays a critical role for personal exposure to air pollutants. It is useful to determine the precise times of the day that the subjects are in certain locations or engaging in specific activities because exposure to some air pollutants can depend on temporal trends. This study investigated time activity pattern for workers of Korean population over 19 years old with 8,778 workers in weekday. The residential indoor times were 12 hours. Time activity was different by gender and the mean times stayed at home in weekday were 12.9 hours in female and 11.42 hours in male, respectively. The major factors on residential indoor time and workplace time were age, monthly income, occupation and industry type, work position, education, and gender. Considering shorter than those in other countries, Korean workers spent less time at home after the working hours. Determinants of time activity pattern need to be taken into account in exposure assessment, epidemiological analyses, exposure simulations, as well as in the development of preventive strategies. Since there are substantial difference of Korean worker activity pattern, this information can be critical for exposure assessment in Korea.

Objectives: The purpose of this study was to compare the difference of Lumbar Lordosis Angle (LLA)between patients with Low Back Pain (LBP) and control groups. Methods: Questionnaires were completed by 40 adults LBP patients seeking physical therapy services and by 40 controls at the department of Physical Therapy, SaeJong Neurosurgical Clinic in Taegu city, South Korea from October 1999 to March 2000. LLA was measured on lateral x-ray films with standing position. The angle between a line parallel to tile top of the first Lumbar (Ll) and the top of the fifth Lumbar (L5) was defined LLA. Results: LLA of 29.88$^{\circ}$ for LBP patients was statistically significant decrease from that of 35.31$^{\circ}$ for controls in the difference of lumbar lordosis (p<0.01). There were statistically significant differences between genders in patients groups. Females(32.22$^{\circ}$) had significantly greater angles than males (27.32$^{\circ}$) (p<0.05), while 36.63$^{\circ}$ for female was also greater than 34.12$^{\circ}$ for male in the controls. No significant difference was found between age. In patient groups, 27.95$^{\circ}$ for below age 40 was a smaller than 32.32$^{\circ}$ for above, however, 35.82$^{\circ}$ for below age 40 was a little greater than 34.27$^{\circ}$ for above in controls. Patients in sitting posture had greater LLA (31.35$^{\circ}$). than those standing (28.93$^{\circ}$), however. values for controls were similar to each other. Conclusions: Results from this study indicate that distinct difference exist among patients and controls and gender, whereas little difference exists in age and working posture.

For basic data to develop health management program of female workers. this study was intended to characterize factors affecting health problems of women at workplace which has less than 50 workers by Cornell Medical Index(CMI). 195 items of CMI questionnaire were simplified to 57 items which were composed of 35 items concerning physical health problems and 22 items concerning mental health problems. The data was collected during 6 months from July 10 to December 30 and analyzed with frequency, percentage, t-test and ANOVA. The 107 female workers included in this study was characterized to be mainly twenties(64.5%), single(69.2%) and working at production position(89.7%). The most frequent physical problem was fatigability and the next, neurological system and cardiovascular system. Main mental complaints were inadquacy. anger and tension. When the health problems were reviewed according to its general characteristics, anger in young age, adaptiveness in single and respiratory complaints in self-recognized unhealthy group were prevalent. According to life styles. the prevalent complaints were musculoskeletal one in alcoholic group and cardiovascular one in group who are sleeping just for four to five hours. The appropriateness of each items of CMI should be evaluated to reveal the reasons why meaningful results could not come from many items of this questionnaire. The repeated study should be carried out to figure out the health problems and its related factors of female workers at small scale workplace. Also, exercise program and abstinence from drinking and smoking should be carried out for female worker's health.
