The purpose of the study was to examine the effect of motif categories and motif colors on evaluating sensory image of fashion materials with the gestalt theory as the background. The research was conducted on a quasi experimental basis, with subjects numbering 187 male and 207 female college students. Data were collected in the period from march 19th to march 31st, 2007. A set of fabric stimuli and semantic differential scales were developed. The stimuli were thirteen fabric species(each measuring 12 by 13cm). Variables included; (a) motif colour(white, grey, pink and blue) (b) motif categories(plain, paisley, flower, stripes and zebra effect). The semantic differential scale to measure sensory image of fabric stimuli included 23 sets of bi-polar adjectives. The data were analysed by factor analysis and ANOVA and the major finding were as follows. 1) Four sensory dimensions emerged of importance: salience, attractiveness, comfort and softness. 2) The motif category effected on the four sensory image dimensions while the motif colour effected on salience, comfort and softness sensory dimensions. 3) An interaction effect was founded between motif category and motif colour. 4) Motif category showed significant effects on the preference and liking of the fashion, however the motif colour did not show any significant effects on the preference and liking. As a whole the results supported the gestalt theory and the results can be used for the marketing strategy for developing fashion fabrics.

We report the detection of a quasi-sinusoidally modulated optical flux with a period of 4.6343 hour in the optical and infrared band of the Fermi source 2FGL J2339.7-0531. Comparing the multi-wavelength observations, we suggest that 2FGL J2339.7- 0531 is a ${\gamma}$-ray emitting millisecond pulsar (MSP) in a binary system with an optically visible late-type companion accreted by the pulsar, where the MSP is responsible for the ${\gamma}$-ray emission while the optical and infrared emission originate from the heated side of the companion. Based on the optical properties, the companion star is believed to be heated by the pulsar and reaches peak magnitude when the heated side faces the observer. We conclude that 2FGL J2339.7-0531 is a member of a subclass of ${\gamma}$-ray emitting pulsars -the 'black widows'- recently revealed to be evaporating their companions in the late-stage of recycling as a prominent group of these newly revealed Fermi sources.

We performed high-resolution three-dimensional global magnetohydrodynamic (MHD) simulations to study the interaction between the Earth's magnetosphere and a prolonged steady southward interplanetary magnetic field (IMF) (Bz = -2nT) and slow solar wind. The simulation results show that dayside magnetic reconnection continuously occurs at the subsolar region where the magnetosheath magnetic field is antiparallel to the geomagnetic field. The plasmoid developed on closed plasma sheet field lines. We found that the vortex was generated at the magnetic equator such as (X, Y) = (7.6, 8.9) R_E due to the viscous-like interaction, which was strengthened by dayside reconnection. The magnetic field and plasma properties clearly showed quasiperiodic variations with a period of 8-10 min across the vortex. Additionally, double twin parallel vorticity in the polar region was clearly seen. The peak value of the cross-polar cap potential fluctuated between 17 and 20 kV during the tail reconnection.

Purpose: The purpose of this study was to identify the effects of a workbook program on percieved stress levels, maternal role confidence and breastfeeding practices of mothers of premature infants. Method: This study employed a quasi-experimental non-equivalent pre-and-post test to compare the two groups. Data was collected from 32 subjects from March 10. to September 5, 2003 at an NICU located in S. city. In the sample, fifteen mothers were in the experimental group and seventeen were in the control group. A workbook program was provided twice during a period from two-three days after the baby's admission to one week after the first intervention. The instruments used were the PSS and self confidence scale. Data was analyzed by means of frequency, SD, $x^2-test$, Fisher's exact test, Mann-Whitney test, and the Wilcoxon signed rank test. Result: There was a significant difference in perceived stress levels between the experimental and control group (U=2.366, p=.018). There was not a significant difference in maternal role confidence between the two groups (U=1.002, p=.316). There was a significant difference in breastfeeding practice between the two groups ($x^2=4.910$, p=.035). Conclusion: It is concluded that a program using a workbook has a positive effect on decreasing the perceived stress level and increasing breastfeeding practice.

Purpose: The purpose of this study was to investigate the effects of the professional nurse's postpartum breast-feeding support on breast-feeding prevalence for mothers who delivered in Baby-Friendly Hospitals (BFH). Methods: This quasi experimental study was designed with a nonequivalent control group post test. The subjects of this study were 55 mothers who were hospitalized in the delivery room of a university hospital which was selected as a BFH in Daegu from October 1, 2005 to June 30, 2006. Twenty nine mothers were assigned to the experimental group and 26 mothers to the control group. Postpartum breast-feeding support by nurses' telephone calls to the experimental group was provided once a week for 4 weeks postpartum and then once a month for 16 weeks postpartum. Four post tests were given at postpartum week 8, 12, and 16. The control group was given a telephone call at postpartum week 4, 8, 12, and 16. Results: The breast-feeding prevalence of the experimental group was significantly higher than that of the control group for each period. Conclusion: Postpartum breast-feeding support by nurses may be a useful intervention to increase breast-feeding prevalence.

Purpose: The purpose of this study was to evaluate the impact of a protocol of cryotherapy and Tai Chi on women with Fibrolmyalgia Syndrome. Methods: The study design was a pretest and posttest quasi-experimental, nonrandom assignment. The subjects were 48 outpatients with a diagnosis of fibromyalgia based on the American College of Rheumatology Standards. The setting was a University Medical Center in S city. The protocol was self administered ten times a week, for a two week period resulting in twenty treatments. Results: A protocol of cryotherapy and Tai Chi self-help program showed significant improvement in the fibromyalgia impact as measured by reports of physical impairment, feeing good, number of missed work days, ability to perform work, reports of pain, fatigue, rest, stiffness, anxiety and depression as reported by the comparison group (p<.001). No significant differences between the two regarding in reports of the tender points (p=.062). Conclusion: The results suggested that a protocol of cryotherapy and Tai Chi self-help program may be a promising multidisciplinary strategy for fibromyalgia patients.

Purpose: The purpose of this study was to investigate the effects of the Korean Dietary Approaches to Stop Hypertension (DASH) education program on oxidative stress, antioxidant capacity, and serum homocysteine (Hcy) level in elderly Korean women. Methods: This was a quasi-experimental study employing non-equivalent control group pretest-posttest design. The DASH group (n= 27) underwent the DASH education program for 12 weeks, whereas the control group (n= 21) was provided one education session. The survey was conducted before and after the intervention period. Results: In DASH group, monounsaturated fatty acid (MUFA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) intakes significantly increased after the intervention as compared to prior to the intervention. No significant differences were found in the control group. After the intervention, thiobarbituric acid reactive substance (TBARS) and Hcy levels significantly decreased in the DASH group but not in the control group. Conclusion: The DASH education program was effective in reducing oxidative stress and Hcy levels in elderly Korean women.

Purpose: This study was conducted to examine the effects of music therapy on anxiety, sedation, and stress responses of patients during surgery with spinal anesthesia. Methods: A quasi-experimental design with a non-equivalent control group pre-post test was used. There were 55 adults over 19 years of age scheduled for a lower leg surgery with spinal anesthesia: 27 in the treatment group and 28 in the comparison group. Each subject in the treatment group identified their music preference which was used during the period of surgery which usually lasted, 61 minutes. Data were analyzed using chi-square, Fisher's exact test, independent t-test and repeated measured ANOVA. Results: There were significant reported differences in levels of anxiety, sedation, and stress responses which were measured by plasma cortisol levels, heart rate, and respiratory rate. The findings of all the variables were effectively decreased among those in the treatment group than the comparison group. Conclusion: The preference based music therapy may be useful as a non-pharmacological intervention.

Purpose: The purpose of this study was to investigate the effects of biofeedback exercise training on muscle activity and activities of daily livings (ADL) in hemiplegic patients. An experimental group consisting of 17 people, was given biofeedback exercise training for 30- 60 minutes per week for 5 weeks, while a control group consisting of 18 people, was given normal exercise with quasi-experimental design. Result: The results of the study show that biofeedback exercise is effective for improving muscle activity in hemiplegic patients, especially in the hemiplegic limbs. However, this study found no significant differences in ADL and IADL between the experimental and the control groups. It implies that ADL and IADL may not be improved for a short period of time, such as 5 weeks, for people with more than five years of hemiplegia. The study suggests that the effect of biofeedback exercise on ADL and IADL should be determined in hemiplegic patients in acute stage.

Bolted opening structures is widely applied for class 1 machinery of nuclear plant with strict design requirement. As the shape of the bolted opening structure is non-axisymmetric due to the existence of stud bolts although it is almost axi-symmetric, 3D analysis is required to satisfy such kind of design requirements. Because as much as possible trial computations are need to get an optimal design condition in the limited period of basic design, an easy and fast analysis tool is useful in the design stage. In the paper, a transformation technique of non-axisymmetric problem into quasi-axisymmetric has been proposed based on the general purpose commercial code ANSYS. Both the pre-processor which incorporates the technique and prepares data and post-processor which prepares arranged results from the huge output of commercial code have been developed to help the design engineers.
