The present study examines whether pitch range variation in North Kyunsang Korean shows a categorical or continuous function. Specifically, the study is focused on the data imitated by adults and children in the North Kyungsang region. To investigate pitch range variation, the log-produced f0 intervals were measured and statistically analyzed. The results of the study are as follows. First, both the adults' and children's imitations were more categorical than continuous, especially for the HL-LH patterns. For the other pitch accent patterns, such as HH-HL and HH-LH, the curves were continuous or flat for most of the speakers. Second, the children's imitations were poorer than those of the adults. That is, the children's imitative responses were shown as more continuous or flat curves than categorical. For the children, the HL-LH pattern showed a categorical function at the midpoint of the curves, though the shifts were not as distinctive as the adults' data. This implies that the imitative responses of children follow the perceptual and productive trace of adults' speech behavior.

The purpose of this study is to investigate the relationship between depression and ego identity of middle-aged women and to identify the variables that show differences in the depression and ego identity of middle-aged women. The subjects in the study were 321 mothers of high school students whose age were 40-59 years old. The instruments for this study were Beck Depression Inventory(BDI) developed Beck(1978) and translated by Lee(1981) and Ego identity Scale developed Suh(1975) and modified by Nam(1975). The reliability values of BDI range from 0.83 to 0.87 and Ego identity range from 0.81 to 0.85 using Cronbach alpha. The data were analysed by using the SAS program and included Frequency, percentage Pearson Correlation MANOVA, t-test, ANOVA. The conclusion obtained from this study were as follows ; 1) There was a negative correlation(r=-0.21, p=0.0002) between depression and ego identity of middle-aged women. Thus the lower depression the higher ego identity for middle-aged women. 2) According to the analysis of interacting effects of depression and ego identity, there were significant differences in the household income(F=0.38, p=0.0035), level of education (F=6.50, p=0.0001), satisfaction of marriage(F=10.45, p=0.0001), family pattern (F=6.18, p=0.0001), menopausal status(F=7.23, p=0.0001), present disease(F=4.85, p=0.0110) and health status(F=9.00, p=0.0001). 3) There were significant differences on the level of education(F=12.98, p=0.0001) household income(F=5.78, p=0.0007), support of spouse(F=8.58, p=0.0002), satisfaction of marriage(F=20.08, p=0.0001), menopausal status(F=11.32, p=0.0001), present disease(t=2.76, p=0.0062) and health status(F=17.23, p=0.0001) of the depression of middle-aged women. 4) There were significant differences on the patterns of household(t=-2.64, p=0.0086), support spouse(F=3.58, p=0.0291), satisfaction of marriage(F=3.90, p=0.0212), menopausal status(F=4.59, p=0.0108) and disease(t=2.11, p=0.0359) of the ego identity of middle-aged women. On the basis of the above findings the following recommendations are made ; 1) According to results of this study, middle-aged women's depression is correlated with ego identity. Thus when the nurse plans the preventive strategy of middle-aged women's depression, the nurse must be considered with level of ego identity. 2) To study for middle-aged women in depth, further research is need to study regard to middle-aged men and their children.

The magnetoelectric characteristics on layered $Fe_{78}B_{13}Si_9/PZT$ and $Fe_{78}B_{13}Si_9/PZT/Fe_{78}B_{13}Si_9$($t_m=0.017$, 0.034mm) composites by epoxy bonding for magnetic field sensor were investigated in the low-frequency range and resonance frequency range. The optimal bias magnetic field $H_{dc}$ of these samples was about 23~63 Oe range. The Me coefficient of $Fe_{78}B_{13}Si_9/PZT/Fe_{78}B_{13}Si_9(t_m=0.034mm)$ composites reaches a maximum of $186mV/cm{\cdot}Oe$ at $H_{dc}=63Oe$, f=50 Hz and a maximum of $1280mV/cm{\cdot}Oe$ at $H_{dc}=63Oe$, resonance frequency $f_r=95.5KHz$. The output voltage shows linearity proportional to ac fields $H_{ac}$ and is about U=0~130.6 mV at $H_{ac}=0{\sim}7Oe$, f=50 Hz, U=0~12.4 V at $H_{ac}=0{\sim}10Oe$, $f_r=95.5KHz$(resonance frequency). The optimal frequency(f=50 Hz) of this sample is around the utility ac frequency(f=60 Hz). Therefore, this sample will allow for ac magnetic field sensor at utility frequency and low bias magnetic fields $H_{dc}$.

A cation-exchange nanofiber poly(vinylidene fluoride) (PVdF) membrane was prepared by a radiation-induced graft polymerization (RIGP) of sodium styrene sulfonate (NaSS) in the presence of the polymerizable access agents in methanol solution. The used polymerizable access agents include styrene, acrylic acid, and vinyl pyrrolidone. The anion-exchange nanofiber PVdF membrane was also prepared by RIGP of glycidyl methacrylate (GMA) and its subsequent chemical modification. The successful preparations of cation- and anion-exchange PVdF membranes were confirmed via SEM, XPS and thermal analysis. The content of the grafting yield, ion-exchange group, and water uptake was in the range of 30.0~32.3%, 2.81~3.01 mmol/g and 66.6~147%, respectively. The proton conductivity at 20$^{\circ}C$ was in the range of 0.020~0.053 S/cm. From the result, the prepared ionexchange PVdF membrane can be used as a separator in battery cells.

The purpose of study was to find out the relation ship between health perception and health status of clinical nurses. It also identified factors that related to health perception and health status of clinical nurses. The research design was descriptive correlational study. The subjects were consisted of 289 clinical nurses at the university hospital in Pusan. The data were collected from Feb. 12th to Feb. 28th, 2001 by self reporting structured questionnaires. The instruments used for this study were health perception questionnaire developed by Ware and Cornell Medical Index modified by Nam Ho-Chang (1965) for measuring health status. The data were analyzed by SPSS/PC+ program using frequency, percentage, mean, mean mark, standard deviation, t-test, ANOVA, Scheffe test, and Pearson's correlation coefficient. The results of this study were as follows. 1. The mean score of the health perception was $94.70{\pm}8.93$(range : 29-145), which the item mean mark score was $3.27{\pm}$0.31(range 1-5). The score of subarea of the health perception was the highest score in health concern ($4.57{\pm}0.58$) and the lowest score in rejection of sick role($2.94{\pm}0.32$). 2. The mean score of the health status was $102.83{\pm}7.61$(range: 57-114), which the item mean mark score was $1.80{\pm}0.13$ (range : 1-2). The mean mark score of the physical health status was $62.55{\pm}5.35$($1.69{\pm}0.14$) and the mental health status was $40.28{\pm}3.51$($1.83{\pm}0.16$). 3. There were statistically significant difference in the score of health perception according to the presence of disease(F=4.607, P=.011), job satisfaction (F=12.242, P=.000), and job place(F=2.838, P=.038). 4. There were statistically significant difference in the score of health status according to the age(F=3.164, P=.007), presence of leisure time(F=4.308, P=.039), presence of diseases(F=3.215, P=.042), job experience(F=9.064, P=.000), job satisfaction(F=7.182, P=.001), job place (F=5.638, P=.001), job position (F=3.900, P=.021). 5. Health perception of clinical nurse was shown to be positively related to health status(r=.543, p=.000). In conclusion, health perception of clinical nurse working at the university hospital was relatively high, and health status was fine. And the more health perception was high, the more health status was high. Therefore, the health promotion program for clinical nurses, should included health perception.
