Purpose: The purpose of this study was to identify the influences of death perception, terminal care attitude on clinical nurses' terminal care performance for cancer patients. Methods: Data were collected through self-reported questionnaires filled by 526 nurses at a General Hospital in Seoul. Data were analyzed using a multiple regression analysis. Results: Death perception showed a positive correlation with terminal care attitude (r = .45, p < .001), while there was no correlation with terminal care performance. Additionally, terminal care attitude had a positive correlation with terminal care performance (r = .18, p < .001). The explanatory power of nurses' death perception and terminal care attitude toward terminal care performance was 14%. Conclusions: The study results imply that nurses' death perception and terminal care attitude are significant variables affecting terminal care performance.

There were few reports about the fluoride concentration in bone and osteoporotic women. This study was designed to evaluate the relationship between the urinary fluoride concentration and periodontal condition in osteoporotic old women. Twentyeight postmenopausal women(Test group) and twenty-one premenopausal women(Control group) were examined. Bone mineral density(BMD) of lumbar spine(L2-L4) was measured by dual energy X-ray absorptiometry(DEXA). The urine samples were collected at early morning and determined with the help of a fluoride-specific electrode and Tisabbufferd samples. The results were as follows. 1. The mean urinary fluoride concentration in test and control group showed statistically no difference. 2. The bone mineral density(BMD) of the spine in test group was significantly lower than control group(p<0.05). 3. The significant negative correlation was found between BMD level and age after menopause $(p<0.001,\;{\gamma}=-0.526$. 4. The urinary fluoride concentration was not correlated with age, age after menopause and bone mineral density. 5. The urinary fluoride concentration was not correlated with periodontal condition.

We investigated the effect of safflower-seed on fracture healing of fracture model in rat. Fracture healing was evaluated by examining the degree of wound healing macroscopically, radiography, bone histomorphometry and biochemical examination. After 1, 3, 5, 7 days, the would healing was accelerate in safflower-seed diet group. Radiography does not reveal the difference in fracture healing between two group. After 2 weeks, safflower-seed had a significant, stimulatory effect on external callus formation (p<0.05). But after 4, 6, 8 weeks, no difference was observed between normal and safflower-seed dietgroup in callus size. Urinary hydroxyproline, osteocalcin and total alkaline phosphatase decreased significantly (p<0.05) in safflower-seed treated group at 2 week after tracture.

Three isolates belonging to the ascomycetous genus Zygotorulaspora were obtained from the fruits of Cornus officinalis and Smilax china, and flowers of Dendranthema zawadskii var. latilobum in Gongju-si, Korea. Phylogenetic Analyses of the LSU D1/D2 domain and ITS region sequences supported the recognition of two new species: Zygotorulaspora cornina sp. nov. (type strain NIBRFGC000500475 = KACC93346P^PP) and Zygotorulaspora smilacis sp. nov. (type strain NIBRFGC000500476 = KACC93347P^PP). The two novel species revealed no growth on D-Galactose, unlike the other six species in the genus Zygotorulaspora. They are distinguished from each other by their phylogenetic differences and phenotypic characteristics such as assimilation of xylitol, 5-keto-D-gluconate, and ethanol. All species in the genus Zygotorulaspora including the two novel species have phenotypic traits of genus Zygotorulaspora: asci are persistent, sucrose and raffinose are assimilated, and m-inositol is not required for growth, and they are mainly associated with plants.

The MMIC cascode VCO is designed, fabricated, and measured for Ku-band Low Noise Blcok(LNB) system using InGaP/GaAs HBT technology. The phase noise of -116.4 dBc/Hz at 1 MHz offset with output power of 1.3 dBm is obtained at 11.526 GHz by applying 3 V and 11 mA, which is comparatively better characteristics than compared with the different configuration VCOs fabricated with other technologies. The simulated results of oscillation frequency and second harmonic suppression agree with the measured results. The phase noise is improved due to the use of the smallest value of inductor in frequency determining network and the InGaP ledge function of the technology. The chip size of $830\time781\;{\mu}m^2$ is also achieved.

The studies of seven individuals of Asiatic black bears were carried out with radio telemetry from October 2004 to December 2006 in Jirisan National Park. They were attached radio-transmitter and calculated by the 95%MCP and fixed kernel method(95%, 50%). As a result, Mean annual home ranges for female and male asiatic black bears were 71.66$km^2$ and 90.20$km^2$. The seasonal home ranges were calculated 19.81$km^2$ for females and 33.47$km^2$ for males in spring, 30.48$km^2$ for females and 20.26$km^2$ for males in summer, 22.63$km^2$ for females and 23.23$km^2$ for males in autumn and 0.22$km^2$ for females and 0.78$km^2$ for males in winter(F=4.193, P<0.05). The degree of home range overlapped 38%, 12.5% among females, 22.4% among males. Mean elevation of seven bears was 744$\pm$236m in spring, 682$\pm$253m in summer, 937$\pm$218m in fall and 975$\pm$137m in winter(F=8.526, P<0.001). It is assumed that home range sizes and location were closely correlated to environmental characteristics of the habitats and the seasonal variation of home-range was related to distribution of food sources.

This study was undertaken to identify knowledge, attitude, perception and nursing practice toward use of physical restraints, among nurses in long-term care hospitals. We further explored the impact of factors associated with nursing practice toward use of physical restraints. This was a cross-sectional descriptive study in which self-administered questionnaires were collected from 128 nurses working at 11 long-term care hospitals. Descriptive statistics, including t-test, one-way ANOVA, Welch's test, Pearson correlation coefficients and multiple regression, were applied to analyze the data collected. Our results reveal that the participants possess moderate levels of knowledge, attitude, perception and nursing practice toward use of physical restraints. Significant positive correlations were observed between nursing practice and knowledge. Multiple regression analysis showed that the factors significantly related to nursing practice and use of physical restraint were knowledge (${\beta}=0.27$, p=0.002) and attitude (${\beta}=-0.17$, p=0.044), having a total explained variance of 9.0%. The findings from this study suggest that knowledge is the strongest predictor on nursing practice toward use of physical restraints. Thus, we propose that developing and applying evidence-based educational intervention programs to reduce the use of physical restraints in long-term care hospitals are required.

Purpose : The purpose of this study was to investigate dual gender identity, masculine gender identity, feminine gender identity, undifferentiated gender identity with related to Sex, home environments, parental child-rearing attitude of warmth, parental child-rearing attitude of control, role division of parents and determine predictors for dual gender identity. Method : Study subjects were $6^{th}$ grade of primary students with 2,118. Data was collected from Oct to Nov 2003 by using structured questionnaire. Results : ${\cdot}$ Among the children, 345 had masculine gender identity, 529 had feminine gender identity, 526 had undifferentiated gender identity, and 718 had dual gender identity. ${\cdot}$ There were significant differences in the children's sex, mother's age, father's age, mother's educational level, father's educational level, existence of mother's job, father's job, social economic status, sex of siblings, mother's job satisfaction, family structure, family atmosphere, child-rearing attitude(warmth and control), role division of parents($p{\leq}0.001$) among 4 groups. ${\cdot}$ The significant predictors for dual gender identity were children's sex (OR = 0,196, P =0.001), father's age(OR = 31.053, p = 0.020), mother's educational level(OR = 43,980, p = 0.001), father's job(OR=27.465, p = 0.001), social economic status(OR=O.941, p=0.001), sex of siblings(OR = 0.329, p = 0.005), mother's job satisfaction(OR = 0.673, p =0.001), family structure(OR = 0.887, p = 0.001), family atmosphere(OR = 23.786, p = 0.001), parental Child-rearing attitude of warmth(OR = 8.043, p = 0.001) and child-rearing attitude of control(OR = 0.666, p = 0.005), role division of parents(OR = 3.009, p = 0.001). Conclusions : These findings suggest the necessity of broad understandings about factors which influence dual gender role, and construction of combinative model. Also they suggest parent education for establishment of children's dual gender identity.

Objectives : The purpose of this study was to quantitatively assess the degree of Graves' Disease affecting mental health through the results of multiphasic military personality inventory (MPI) in 19-year-old men. Methods : We collected and analyzed the results of the MPI for 592 healthy subjects and 148 Graves' disease patients among the 19-year-old men who visited the Military Manpower Administration from February 2008 to January 2010. Results : Among demographic characteristics, both Graves' disease and control group are 19-year-old men. Educational level, socioeconomic status, parental relationship, and BMI were not statistically different between the two groups (χ²=0.089, p=0.766; χ²=5.090, p=0.278; χ²=5.988, p=0.112 ; t=-0.635, p=0.526). In the MPI, among validity scales, the score of the faking-good subscale was significantly lower in the Graves' group (t=3.507, p<0.001), but in the faking-bad and infrequency subscales scores were not significantly different between two groups (t=-1.700, p=0.090; t=-0.519, p=0.604). Among the neurosis scale, anxiety, depression, somatization, and personality disorder subscale scores were all significantly higher in Graves' disease group (t=-3.323, p<0.001; t=-4.210, p<0.001; t=-6.202, p<0.001; t=-2.872, p<0.01). Among the psychopath scale, each score of schizophrenia and paranoia subscales were not statistically different between the two groups (t=-0.158, p=0.874; t=-0.846, p=0.398). Conclusions : According to MPI result, we can confirm that Graves' disease patients in 19-year-old-men may appear features such as anxiety, depression, somatization and personality tendency (introversion or impulsivity) than the control group.
