The damage level of the die surface was predicted by estimating the surface roughness with a finite element analysis and the wear characteristics. Wear and friction tests were conducted to compare the wear characteristics for three kinds of surface treatments - CrN, TiAlN and AlCrN coatings. A prediction model was derived from the surface roughness results with respect to contact pressure and sliding speed which were obtained from the wear test. Surface roughness values for the damage regions of the die surface were compared between the experiments and the prediction model, which shows fairly good agreement with each other.

The purpose of this study was to develop a large representative data base for character goods marketing strategy. The study was to determine character name awareness in relation to segmented distribution regions and such demographic variables as sex and age. The author also analyzed preferred design. A total of 360 questionnaires were distributed and 359 reliable ones were used for statistical analysis. A SAS statistical package including frequency tables and Chi square test and factor analysis and Kendall′s relation analyses was used. The results are as follow : character name awareness involves "character name decognition" based on asking subjects to identify character names from 50 given names. "Tele-tubbies" was found to be a dominant commercial character name as a result of the recognition test, and "Sailer-moon" was found to be a dominant animation character goods as a result of the recognition test. Character recognition was significantly different in the segmented distribution legions, three age groups and different sex groups. People considered design first in purchasing any character goods, and they considered color second in purchasing them. The most favored part of garment far character to be stitch to was the center front in the T-shirt/dress shirt, the center back in the Jumper/jacket, back pocket in the trousers/skirt. The results of a Chi-square test showed that preferred part in the trousers/skirt of character was related with age variables.

Purpose: The aim of this study was to develop a breast feeding adaptation scale (BFAS) to evaluate adaptation to breastfeeding for breastfeeding mothers and their infants and to test the validity and reliability of the instrument. Methods: The study was conducted as follows: application of the conceptual framework, identification of the content domains, items generation, and test of validity and reliability. In order to test validity and reliability, two panels of experts reviewed items and subcategories of the preliminary questionnaire and then data were collected from 329 mothers who were up to 4 weeks postpartum and breastfeeding. Descriptive statistics, t-test, factor analysis, and Cronbach's alpha were used to analyze the data. Results: The conceptual framework was based on the Roy adaptation model. The content domains were developed via literature review, review of instruments, and data acquired from the interviews of breastfeeding mothers and nurses. A total of 69 items belonging to 8 domains were generated. A reduction to 44 preliminary items was accomplished through content validity analysis. Factor analysis extracted 8 factors with a total of 27 items on a 5-point Likert scale. Content validity, construct validity, criterion validity, and reliability of the BFAS were established. Conclusion: The newly developed BFAS is a reliable and valid instrument with which the adaptation of breastfeeding mothers and their infants to the breastfeeding behavior can be evaluated.

This study aimed to present a reinforced concrete block system that reduces the flange thickness of the existing form block used in new buildings and optimizes the web form, and can thus capable of being used in the seismic retrofit of new and existing buildings. By conducting a compression test and finite element analysis based on the block and grouted concrete strength, it attempted to determine the compression capacity of the form block that can be used in new construction and seismic retrofit. As a result, the comparison of the strength equation from Architectural Institute of Japan to the prism compression test showed that the mortar coefficient of 0.55 was suitable instead of 0.75 recommended in the equation. The stress-strain relation of the block was proposed as a bi-linear model based on the compression test result of the single form block. Using the proposed model, finite element analysis was conducted on the prism specimens, and it was shown that the proposed model predicted the compression behavior of the form block appropriately.

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.

Aceclofenac is an orally effective non-steroidal anti-inflammatory agent of the phenylacetic acid derivative. Bioequivalence study of two aceclofenac preparations, the test drug (Senafe $n_{R}$: Daewon Phar-maceutical Company) and the reference drug (Airta $l_{R}$: Daewoong Pharmaceutical Company), was conducted according to the guidelines of Korea Food and Drug Administration (KFDA). Sixteen healthy male volunteers, 24$\pm$4 years old and 63.9$\pm$6.9 kg of body weight in average, were divided randomly into two groups and administered the drug orally at the dose of 100 mg as aceclofenac in a 2$\times$2 crossover study. Plasma concentrations of aceclofenac were monitored by HPLC method for 12 hr after administration. AU $Co_{-12h}$ (area under the plasma concentration-time curve from initial to 12 hr) was calculated by the linear trapezoidal method. $C_{max}$ (maximum plasma drug concentration) and $T_{max}$ (time to reach $C_{msx}$) were compiled directly from the plasma drug concentration-time data. Student's t-test indicated no significant differences between the formulations in these parameters. Analysis of variance (ANOVA) revealed that there are no differences in AU $Co_{12h}$, $C_{max}$ and $T_{max}$ between the formulations. The apparent differences between the formulations were far less than 20% (e.g., 0.25, 0.01 and 7.32 for AU $Co_{-12h}$, $C_{max}$. and $T_{max}$, respectively). Minimum detectable differences (%) between the formulations at $\alpha$=0.05 and 1-$\beta$=0.8 were less than 20% (e.g., 14.65, 12.47 and 15.46 for AU $Co_{-l2h}$, $C_{max}$ and $T_{max}$, respectively). The 90% confidence intervals for these parameters were also within $\pm$ 20% (e.g.,-10.19~10.68, -8.87~8.89 and -3.69~ 18.33 for AU $Co_{-12h}$, $C_{msx}$ and $T_{max}$, respectively). These results satisfy the bioequivalence criteria of KFDA guidelines, indicating that two formulations of aceclofenac are bioequivalent.quivalent.ivalent.ent.t.ent.
