Purpose: This study has been designed to identify attitudes to euthanasia held by Korean nurses. Method: Data were collected through a survey, and the participants in the study were 234 Korean nurses. Convenience sampling method was used and analysis of the data was done with SPSS PC for descriptive statistics, t-test and ANOVA. Results : 1. The mean score for euthanasia was 2.80. and the sub dimension mean scores were, patients' rights. 3.24, quality of life, 2 78, respect for life, 2.68, medical ethics, 2.50. 2. With respect to the general characteristics of participants there were statistically significant difference in total score according to religion (P= .01), and degree of influence of religion on behavior (P= .00). 3. There were statistically significant difference in score of quality of life according to religion (P= .04), degree of influence of religion on behavior (P= 00), decisions in euthanasia (P=.04), and legal permission (P= .04). 4. There was statistically significant difference in score of patient's right according to legal permission (P = .04). 5 There were statistically significant difference in the score of respect for life according to religion (P= .00), degree of influence of religion on behavior (P= .00), decision in euthnasia (P= .00), and legal permission (P= .00).

In this paper proposed the solar tracking system to use a fuzzy based on PC in order to increase an output of the PV array. The solar tracking system operated two DC motors driving by signal of photo sensor. The control of dual axes is not an easy task due to nonlinear dynamics and unavailability of the parameters. The fuzzy control made a nonlinear dynamics to well perform and had a robust and highly efficient characteristic about a parameter variable as well as a nonlinear characteristic. Hence the fuzzy control was used to perform the tracking system after comparing with error values of setting-up, nonlinear altitude and azimuth. In this paper designed a fuzzy controller for improving output of PV array and evaluated comparison with efficient of conventional PI controller. The data which were obtained by experiment were able to show a validity of the proposed controller.

Purpose: This study was to analyze the differences of job satisfaction, organizational commitment, nursing organization culture and intention of separation between national/public and private hospital nurses and thereby, provide for some basic data useful to effective management of nursing human resources and improve the organizational performances. Method: The researcher sampled 464 clinical nurses working for 4 national/public hospitals and the same number of private hospitals in Seoul and Gyeonggi Province. The data collected from the questionnaire survey were statistically processed using the SPSS PC 12.0 program for $X^2$-test, T-test and ANCOVA. Result: 1) There was found no significant difference of job satisfaction scores between national/public hospitals and private hospitals. 2) National/public hospital nurses scored significantly higher than private hospital nurses on the organizational commitment scale. 3) There was no significant difference of nursing organization culture scores between national/public hospitals and private hospitals. 4) In the area of job experience, national/public hospital nurses scored lower than private hospital nurses, but such a difference was not significant. Conclusion: Difference between two groups was significant only in the area of organizational commitment. In terms of sub-areas, the difference between two groups was significant in professionalism conducive to job satisfaction.

We present results of the VLBA observation toward the radio continuum and water maser emissions in a nearby LINER galaxy NGC 1052. The jet structure observed in 2000 is similar to that in 1998, and the two jet structures in 1998 and 2000 support the sub-luminal motion with apparent velocity of 0.26c. Distribution of water maser spots are located ${\~}$0.05 pc shifted to southwest from the component which is supported to be the nucleus, and no rapid positional change of the water maser gas with respect to the central engine is seen from 1995 to 2000. The maser gas is positionally coincident with a plasma torus, and the position of the maser gas relative to the nucleus is stable from 1995 to 2000. The maser gas in NGC 1052 could be explained to be associated with the nuclear circumnuclear torus or disk like the situation found in the nucleus of NGC 4258.

The purpose of this study was to investigate the effect of parent-bonding patterns & environmental variables on rural high school students' self-differentiationf. The subjects were 600 rural high school students in the 2nd grade. The rural high school students' self-differentiation, according to parent-bonding style & environmental variables were researched with DOSS(Differentiation of self Scale) PBI(Parent-bonding Instrument) & environmental Scale. The data were analyzed by frequency & Reliability, ANOVA (scheffe'test) & Regression analysis of SPSS PC+ program. The main results were as follows. First, In P-B patterns generally frequencies of mother's care were higher than father's But in overprotection frequencies of father's were higher. Degree of rural highschool students' self-differentiation was on the level of 2.84 Second, According to parent-bonding patterns, the difference of self-differentiation were as follow. In P-B patters, father and mother on each level of P<.001 brought differences in the self-differentiation of the 4 sub-divisions Third, In short the effect on self-differentiation showed that in family environmental variables, parent's scolding, gender, family atmosphere & health conditions are crucial variables in self-differentiation and in P-B patterns, father's overprotection, mother's care, father's care are all influential on self-differentiation.

VolumePro is a real-time volume rendering hardware for consumer PCs. However it cannot be used for the applications requiring perspective projection such as virtual endoscopy since it provides only orthographic projection. Several methods have been presented to approximate perspective projection by decomposing a volume into slabs and applying successive parallel projection to thou. But it takes a lot of time since the entire region of every slab should be processed, which does not contribute to final image. In this paper, we propose an efficient perspective projection method that makes the use of several sub-volumes with cropping feature of VolumePro. It reduces the rendering time in comparison to slab-based method without image quality deterioration since it processes only the parts contained in the view frustum.

In this study, Multi-Array Electrodes (MAE) and Programmable Multi-channel Electrical Stimulator (PMES) were implemented for firing Trigger Points (TPs) of the patient with Myofascial Pain Syndrome (MPS). MAE has 25 Ag/AgCl electrodes arranged in the form of array ($5{\times}5$) fabricated with flexible pad, which are applicable to be easy-attached to curved specific region of the human body. PMES consisted of 25 channels. Each channel was to generate various electric stimulus patterns (ESPs) by changing the mono-phasic or bi-phasic of ESP, On/Off duration of ESP, the interval between ESP, and amplitude of ESP. PMES hardware was composed of Host PC, Stimulation Pattern Editing Program (SPEP), and Multi-channel Electrical Stimulator (MES). Experiments were performed using MAE and PMES as the following. First experiment was performed to evaluate the function for each channel of Sub- Micro Controller Unit (SMCU) in MES. Second experiment was conducted on whether ESP applied from each channel of SMCU in PMES was focused to the electrode set to the ground, after applying ESP being output from each channel of SMCU in PMES to MAE.

The CMV promoter driven lacZ reporter gene (pcDNA-lacZ) was constructed and used for DNA immunization study. The expression of the lacZ gene was confirmed in vitro using RTG-2 cell line before using for in vivo study in olive flounder (Paralichthys olivaceus). In the dose response study, the maximum expression of the lacZ gene was found in the group injected with 5 ${\mu} g$ of the plasmid DNA. Kinetic study showed a significantly increased expression of $\beta-galactosidase$ gene at 7 days after injection. Effects of DNA vaccine on specific and nonspecific immune responses such as antibody and NO production were studied and the significant effect was found in olive flounder injected with 10 and 15 ${\mu} g$ DNA (sub optimal dose for lacZ gene expression). Two pro inflammatory cytokine genes, $IL-l\beta$ and $TNF-\alpha$, were also found to be up regulated in the muscle injected with the plasmid, suggesting an induction of local inflammatory response.
