The propose of the study was to evaluate impression effects and likeness of clothing styles and make-up types. The stimuli were composed of 4 clothing styles(base, natural, romantic, classic) and 4 make-up types(no make-up, natural, romantic, classic). The subjects were 512 male and female university students in Daejeon and Chungnam province. The study consisted of a survey and quasi- experiment. The experimental materials used for this study were 16 stimuli, 32 hi-polar adjectives, and likeness scale were composed of 7-point Likert type scales. As a result, the clothing styles and make-up types effected on the 4 impressional dimensions: grace, evaluation, salience, and dynamism. The clothing styles effected on grace, salience and dynamism dimension and the effect of dynamism dimension was the most powerful among the dimensions. The make-up types effected on all of the 4 impression dimensions and the effect of salience dimension was the most powerful among the dimensions. The interaction effects existed between the clothing styles and make-up types in salience dimension. The likeness showed significant difference only on the make-up types. The effect of grace dimension was the most powerful among the dimensions. The main reason that make-up effect appears greatly could be analyzed into that clothes color is controlled by white. The results suggest the necessity of succession study about the effect of clothes color.

Baroclinic hydraulic model experiments on the time-varying states of the flow pattern and water exchange in Sagami Bay were carried out based on quasi-steady state experiments on the flow pattern. For the model experiments, density changes as well as time changes in the volume transport of the upper layer were executed to investigate the flow response of the bay in the case of a sudden inflow of low density water and variable volume transport into the Sagami Bay. The results of the model experiments showed that when the volume transport was increased frontal eddies or frontal wave streamers from the Kuroshio Through Flow were transferred to the inner part of the bay along with cyclonic circulation in the bay. In addition, density boundary currents appeared and flowed along the eastern boundary of the bay. As the upper layer density decreased, frontal eddies, frontal streamers and coastal boundary density currents occurred and proceeded along the eastern boundary of the bay at a high speed.

Purpose: The purpose of this study was to exam the effects of nursing information about intensive care unit environment on ICU patient's environmental stress, anxiety and comfort. Methods: A non-equivalent control group with non-synchronized quasi-experimental research design was used. Participants were 60 (control 30, experimental 30) patients who admitted at ICU in one hospital in Gangneung. Experimental group was provided with nursing information about intensive care unit environment. To avoid contamination of the experiment, data for the control group were collected prior to the experimental group. Paired t-test, t-test, chi-square test were used to analyze the data using the SPSS WIN 19.0 Program. Results: ICU environmental stress (t=-.089, p=.045) and anxiety (t=-5.65, p<.001) were significantly more reduced than before intervention. Also, comfort (t=-2.98, p=.036) was significantly more improved than before intervention. Conclusion: It confirmed that nursing information on ICU environment is effective in reducing environmental stress, anxiety and improving comfort in ICU patients.

An active inspection system using Lamb waves for structural health monitoring was considered in this paper. In order to understand the characteristics of the Lamb waves propagating in a composite plate, the experiment was performed for a quasi-isotropic composite plate with thickness variation. Lamb waves were generated and received by the thin PZT transducers bonded on the surface. In this test, a simple new technique was tried for characterizing the Lamb waves propagating across the discontinuity due to the thickness variation. The results showed that Lamb waves were more sensitive to the thinner plate with faster group velocity and that the thickness change in composite plate was detectable. Consequently, the potential of applying this technique to structural health monitoring was verified.

The objectives of this study were to investigate differences between image perceptions according to gender, place of residence, and fashion trend; and to examine how the image of preferred clothing was evaluated in each given area of fashion trend. Subjects were 386 schoolchildren (boys:196, girls:190) in Seoul, Daejeon, and Jinju, Korea. Based on a quasi-experiment study, a survey was conducted with a questionnaire providing different clothing images of fashion trend. Stimuli were 5 colored photo pictures of a girl wearing clothing according to fashion trend. The clothing used in the study met requirements of 2004 S/S trend of children's clothing. The high valued clothing sold in three target places were used. There was a significant difference in image perceptions between two sexes. Girls showed more positive attitude in image perceptions toward fashionable clothing in most areas than boys. Children from smaller towns evaluated the model clothing more fashionable. Schoolchildren preferred sporty clothing to the other fashionable clothing. In view of trend, romantic clothing normally viewed less dynamic were evaluated preferable clothing when children viewed the clothing active. Sports-wears were considered fashionable when they viewed the clothing neat and vigorous.

Vortical structures in the near-wake region of a cubic obstacle are studied using numerical simulation. We consider flow between two parallel plates with a cube mounted on one of the plates. In the turbulent near-wake region of the flow, coherent structures such as hairpin vortices are found. Quasi-periodic behavior of the hairpin vortices is noticed; its dimensionless frequency at Re=1,000 is about 0.82 which is consistent with the result of Elavarasan of et al.'s experiment [Fluid Dyn. Research, 2000, 27] although their geometry is somewhat different from on. In the case of Re=3,500, the dimensionless frequency of the hairpin vortex is about 1.60. It is observed that the translating speed of the head of the hairpin vortex is lower than the streamwise mean velocity at that location. In the vicinity of the lower plate downstream of the cube, various length scales are identified thus less coherent. However, it is noticed that the vortical structures become gradually elongated downstream of the new reattachment.

The purposes of the study were 1) to extend the cognitive categorization theory in an attempt to explain the of garment category, fashionability, and wearer's body types on impression formation, and 2) to find out structures of wearer's impressional dimension and wearer's professional image. The research included a quasi-experiment and survey. The experimental design was a $2^{3}$full factorial design of 3 independent variables. The experimental materials developed for the study were a set of stimuli and a response scale. The stimuli consisted of 8 drawings made by 3 independent variables (garment category, fashion level, wearer's body type). Result were as follows: 1) Garment category, fashionability and wearer's body type had significant effects on impression of the 5 factors-evaluation, potency, appearance, sociability and good-bad, with exception of wearer's body type which was nonsignificant to the potency factor. 2) Garment category was most effective on the evaluation and the potency. However wearer's body type was most effect on the appearance factor and fashionability variable was most effective on the good-bad factor. It was conclued that the results supported the cognitive categorization theory on impression formation and a cognitive categorization hypothesis of clothes.

Purpose: This study was to verify the effects of infant massage on weight recovery from physiologic weight loss, physical development of infants, and identity of their mothers. Method: A study with quasi-experimental design with time delay method was conducted from October 20, 2004 through February 20, 2005 with mothers and infants recruited from postpartum care center. 20 infants in the experimental group (once a day massage group) and 22 control group remained for the final analysis. Data were analyzed using SPSS win 11.0 program by frequency, percentage, mean, standard deviation, t-test and $X^2-test$. Results: There was no significant group difference in weight recovery from physiologic weight loss. However, experiment group showed significant increase in weight and chest circumference in 4 weeks after birth compare to the control group. For changes in behavior, experimental group showed more positive behavioral changes. The mothers who conducted massage for their infants showed higher score of identity as mothers. Conclusion: Since massage applied once a day can be still effective on physical growth of the infants, massage training program for mothers should be developed to apply easily for their infants at home. Further study is suggested to identify influencing factors on performed by mothers and identity as mothers.

The purpose of this study was (1) to identify the experimental bias which could appear person perception as results of presentation methods (2) to find out the most desirable method in presentation of stimulus. The research was a quasi experiment and the subjects were 773 male and female undergraduate students. The experimental instruments consisted of a set of stimulus and semantic differential scales of 7- point hi-polar adjectives. The collected data were analyzed by Factor Analysis, ANOVA(analysis of variance), Scheffe＇s multiple range test. The independent variables were presentation orders and presentation time of stimulus. The results were as follows: First, five factors which were potency, sociality, appearance, evaluation, activity impression dimensions emerged to account for the methods of development of stimulus. Second, the presentation order of stimulus in the combination of four stimuli sets had significant effects on the 3 impressional factors(sociality, appearance, evaluation). The presentation order of stimuli in the combination of eight stimuli set had significant effects on the 3 impressional factors(potency, sociality, appearance) and the presentation order of stimuli in the combination of eight stimuli set showed a significant effect on memorization of stimulus and the results support the recency effect. Third, the presentation time of stimuli had significant effects on the 2 impressional factors(potency, activity). 30 seconds presentation as well as free duration time resulted less experimental bias than 3 seconds presentation.
