This study was conducted to investigate the effect of the total digestible nutrients (TDN) level of commercial concentrates on growth performance, carcass characteristics, and meat composition of late fattening Hanwoo steers. A total of 28 steers were randomly assigned to one of four dietary groups; T1 (73.30% TDN), T2 (74.50% TDN), T3 (76.40% TDN), and T4 (77.10% TDN). Average daily gain (ADG) was slightly but not significantly higher in the T2 than in the other treatments. Dry matter intake (DMI) and feed conversion ratio (FCR) were higher in the T2 than in the other treatments; however, the differences were not statistically significant. Carcass back fat thickness was thicker in the T4 and marbling score was higher in the T2 than in the other treatments; however, the differences were not statistically significant. The TDN level of concentrates had no effect on the physicochemical characteristics and fatty acid composition of the longissimus muscle. The finding of this study indicate that less than 74% or greater than 75% TDN in the commercial concentrate did not contribute to improve ADG, FCR, marbling score; therefore, in the present study, the recommendable TDN level in the commercial concentrate for late fattening period was 74% to 75% in terms of growth performance and marbling score of Hanwoo steer.

Purpose: The aim of this study was to evaluate the relationship between maternal periodontal disease and the health status of newborns using Apgar scores. Methods: One hundred pregnant women with periodontal disease were included in the case series and 100 pregnant women without periodontal disease were placed in the control group, respectively. The periodontal parameters of bleeding on probing (BOP), clinical attachment loss (CAL), probing depth (PD), birth weight, and Apgar scores were recorded in both groups. T-tests and Pearson's correlation coefficient were used to determine the birth weight odds ratio to analyze the relationship between the periodontal parameters of BOP, CAL, and PD on the one hand and an Apgar score of less than 7. An unpaired Student's t-test was used to analyze differences in means between the case and control groups using SPSS ver. 13. Results: The means of the ages, periodontal pocket depths, attachment loss, areas with BOP, Apgar score in the first 5 minutes and infant birth weight exhibited statistically significant differences between the case and control groups. The ratio of an Apgar score of <7 to periodontal disease was 3.14; the ratio of low birth weight risk in mothers with periodontal disease to that in mothers without periodontal disease was 2.74. Pearson's correlation coefficient revealed a significant correlation between the infant birth weight and BOP, CAL, and PD of the mother. In addition, there was a significant correlation between the Apgar score and BOP, CAL, and PD and also between the Apgar score and infant birth weight. Conclusions: The results of this study showed a significant relationship between periodontal disease and infant birth weight; in addition, there was a significant relationship between the periodontal indexes of BOP, CAL, and PD on the one hand and the Apgar score on the other.

Health care for women regularly focuses on the reproductive system to the exclusion of other health needs. The lack of research focusing on women's common health issues is a major problem to the enhanced optimal level of women's health. Health care providers have to recognize biological and social differences between men and women. This study was conducted to identify the baseline data and their correlation of health perception, health behavior, and health status of adult women for developing nursing intervention. The study was a descriptive correlational design. A convenient sampling method was used for collecting data from 103 adult women, over 18 years of age, during the period from Sep 1 to Nov 30, 2001. The study's subjects were interviewed using a structured questionnaire. The instruments for this study were the health perception scale modified by Lee(1985) based on the tool developed by Ware(1977) and Jenkins (1966), and the health behavior scale by Ko, Kumja(1987). Health status was measured by the short form Cornell Medical Index(CMI) modified by Nam, Hochang(1965). The data were analyzed SPSS PC+, by frequency, mean, t-test, ANOVA, and Pearson correlation coefficients. Also, the Duncan test was utilized for a post hoc test of ANOVA. The results of this study are as follows: 1. The mean score for health perception was 3.02(S.D=0.39) on a 5 point scale. 2. The mean score for health behavior was 3.08(S.D=0.43) on a 5 point scale. 3. The mean score for health status was 18.54 on 58 items. The mean score for physical symptoms of a subscale of health status was 11.30 on 36 items and the mean score for psychological symptoms was 7.37 on 22 items. 4. The relationship of sociodemographic variables to health perception. health behavior, and health status of women.: 1) There were significant differences in the scores of health perception by disease experience(t=-3.37, p=0.00). 2) There were significant differences in the scores of health behavior by age(F=10.52, p=0.00), height(F=4.73, p=0.01), marital status(t=-5.56, p=0.00), educational background(t=2.90, p=0.00), and drinking or non-drinking(t=2.17, p=0.03). 3) There were significant differences in the scores of health status by educational background(t=2.28, p=0.02) and disease experience(t=2.61, p=0.01). 5. Health perception showed significant positive correlation with health behavior(r=0.39, p=0.00). Health perception showed significant negative correlation with health status(r=-0.44, p=0.00), that is, the more women perceived health, the less she complained about unhealthy symptoms. Health behavior had no significant correlation with health status but showed a positive correlation with psychological symptoms of a subscale of health status(r=-0.19, p=0.05). Many of the leading causes of disease are preventable through changes in health perception and behavior. The need to increase individual awareness of relationships among health perception, health behavior, and health status and to enhance knowledge regarding the long-term effects of positive health behaviors, is an important nursing strategy for women's health promotion.

Purpose: The purpose of this study was to identify the degree of Job stress and Coping of the nurses in ICU and Cancer ward, and to compare the Job stress and Coping between two groups, and finally to get the basic information about the adequate method to promote Coping about Job stress of the nurses in ICU and Cancer ward. Method: The subjects of this study were 131; 62 nurses in ICU and 69 nurses in Cancer ward. Data were collected from 27th August to 14th September in 2007. The instruments for this study were Job stress scale(55 items) developed by Kim(1989), and Coping scale(32 items) developed by Lazarus and Folkman(1984) and revised by Han and Oh(1990). For the data analysis, SPSS PC/win 12.0 program was utilized for descriptive statistics, $X^2$-test, t-test, Pearson correlation. Result: The results of this study were the followings; The mean score of Job stress(range 1-5) was 2.93 in ICU nurse and 2.58 in Cancer ward nurse. There was a significant difference (t=4.453, p<.01)between them. There were significant differences in subscale of Job stress between the two groups, such as Nursing job(t=3.717, p<.01), Job circumstances(t=4.558, p<.01), Personal relations(t=3.425, p<.01), Hospital administration and ward management(t=2.94, p<.01). The mean score of Coping(range 1-4) was 2.55 in ICU nurse, and 2.54 in Cancer ward nurse; there was no significant difference. But one subscale of the Coping(Search of social support) showed significant difference(t=-2.865, p<.01). There was no significant correlation between Job stress and Coping of ICU nurse vs Cancer ward nurse except one subscale in cancer ward(correlation between Nursing Job and Coping). Conclusion: The ICU nurse is higher than the Cancer ward nurse in the Job stress score significantly and lower than the Cancer unit nurse in the Coping. Based on the study results, it is needed the program development using the Coping methods in accordance with ward speciality to relieve Job stress.

Purpose: This descriptive study compared the perceived parental stress levels between parents with very low birth weight infants (VLBWIs) and nurses in the neonatal intensive care unit (NICU). Methods: In total, 83 parents of VLBWIs and 78 NICU nurses were enrolled. Data were collected with the Parental Stress Scale (PSS) and analyzed using the t-test and analysis of variance in SAS version 9.4. Results: The average PSS score was 3.31 among parents and 3.45 among nurses. The stress score was significantly higher among nurses with children (t=2.46, p=.016) and senior nurses (t=2.12, p=.037). There was a significant difference in the stress score according to parents' education (t=3.29, p=.002) and occupation (F=3.14, p=.049) in the sights and sounds subscale. Mothers had significantly higher stress scores than fathers in the parental role alterations subscale (t=2.32, p=.023). Parental stress scores were higher than those perceived by nurses in the infant's appearance and behaviors subscale for breathing patterns (t=2.95, p=.004), followed by jerky/ restless behavior (t=2.70, p=.008). Conclusion: Nurses should provide explanations to parents of VLBWIs in order to reduce parental stress about the appearances and behavior of VLBWIs. This is more important than aspect of the NICU environment and education about parental roles.

Purpose: The purpose of this study was to determine the effect of physical performance on bone mineral density (BMD) in elderly women. Methods: Twenty-one elderly women participated in this study. After testing functional ambulation category (FAC), they were classified into two groups: dependent walking group, those who could not walk independently (FAC 0~2, n=11) and independent walking group those who could walk independently (FAC 3~5, n=10). Outcome measures were: general characteristics, physical performance and BMD. General characteristics included age, body mass index (BMI) and waist-hip ratio. Physical performance included the chair rise test (CRT) and the modified fall efficacy scale (MFES). BMD was represented in the osteoporosis index (OI), T-score and Z-score. BMD was evaluated in calcaneal bone, using OsteoPro. The data was analyzed using SPSS 12.0 software and the Mann-Whitney U test and the Spearman correlation. Results: Age, BMI and waist hip ratio, which all affect BMD, showed no significant differences between groups (p>0.05). But the FAC 3~5 group showed a significantly higher score for CRT, MFES and T-score, compared with the FAC 0~2 group (p<0.05). The T-score was correlated with CRT and MFES scores (p<0.05). Conclusion: There is a positive relationship between physical performance and BMD. Therefore, improved physical performance can have a beneficial effect by reducing osteoporosis in elderly women, considering a positive relationship between physical performance and BMD.
