Today's Virtual Reality(VR) technology has become considerably more affordable and sophisticated with rapidly advancing computer technology. Photo-realistic visual representations along with real-time interactivity are now achievable without special programing knowledge and expensive equipment. The purpose of this paper is to establish how simple, credible user testing methods based on VR simulations can be utilized to improve design decision making towards more sensible design solutions for end-users. Results of a case study demonstrate the value of potential user-testing feedback in a simulated 3D virtual service space, i.e., restaurant interior. User feedback from the VR simulation includes preferences in table location, privacy, and values of seating preferred tables. A new design framework incorporating an empirical testing method for service spaces is presented. The overall design process, the development of the VE, and the user testing method and findings are discussed. This study provides useful guidances for future efforts in the areas where such technology may benefit to understand end-user feedbacks in design process.

To use bamboo in the pulp industry, the anatomical characteristics of 60-day-old, 1-year-old, 2-year-old, and 3-year-old moso bamboo (Phyllostachys pubescens Mazel), and the characteristics of fiber and sheet of alkali pulp made of moso bamboo were investigated. Moso bamboo is composed of metaxylens and parenchyma cells in the inner part of the wall, and thick-walled small bundle sheathes near the outer walls. Moso bamboo showed the heterogeneity in anatomical structure. The longest fibers were shown in the middle part, and the widest width in the inner part. The lignin contents were 14.4% in 60-day-old bamboo, which was not lignified yet. The lignin contents in bamboo above 1 year were approximately 35%. The yields of alkali pulp of moso bamboo were in the range between 41 and 47%, and the yields tend to decrease with the increase of ages. The lignin contents of 60-day-old bamboo were 2.1% and those of bamboo above 1 year showed approximately 4% to 5% increment. The length, width, and curl index of fiber in alkali pulp appeared to be similar in all ages. However, coarseness increased slightly with the increase of bamboo ages. The distribution of long fiber was shown much in 60-year-old bamboo. The optical and mechanical properties of moso bamboo tended to decrease with the increase of bamboo age.

A series of model tests were conducted to investigate how the number of reinforcement layers, stiffnesses, types of reinforcement material and buried depth of a flexible pipe can affect bearing capacity-settlement curve at a loose sand foundation. In the test results, whereas the type of failure in unreinforced sand was local shear, the type of failure, for model tests with more than 2 reinforcement layers in loose sand, was general shear: The number of the optimum reinforcement layers was found to be two: Stiffness and type of reinforcement were more important than the maximum tensile strength of reinforcement in improving bearing capacity. When the depth of buried pipe from the sand surface was less than the width of the footing, test results showed that both bearing capacity and ultimate bearing capacity of buried pipe in unreinforced sand significantly decreased, and the type of failure in the reinforced sand changed from general shear to local shear.

The purpose of this study is to find out the changes on the metropolitan condominium apartment unit plans based on the interior spaces related to women such An-bang (master bedroom), bathroom and attached spaces to the master bedroom, living room, diningroom, kitchen, utility room, and balcony. This study used the content analysis method and space syntax. Contents were limited to the floor plans with 3 rooms type and about 105 m2 in the Korean apartment encyclopedia. The unit plans of 2,278, built from October 1975 to January 2008, were analyzed and basically SPSS package 16.0 was employed. The results were as followed. 1) Living room was a core space and an increasing tendency. After 2001, the design trend of living room connected with kitchen and dining room, and dining room changed into one space combining with women's working space such kitchen. It meaned women's working activities became into family public activities as to depending open access. 2) Kitchen had a characteristics that was connected to utility room or back balcony, and the number of extra kitchen increased. Also, the size of DK decreased, but utility size little increased. It was showed the characteristic of this space was still for women. 3) An-bang had a little strong characteristics of married coulpe or women's personal space with bathroom or dress room/powder room. 4) In addition, the values of integration and control of living room and DK were highest. It meant these space were centered in unit plans. Next, the An-bang and dress room/powder room were high. Utility room or balcony's were next, and these were women's working space. Therefore, family's public space was most important, and married couple or women's personal and working space were later in planning.

The blood samples were collected from dairy cows at the same milking stage. The single-strand conformation polymorphism (PCR-SSCP) method was used to analyze for polymorphism at the 5'flanking region of the hsp70 gene. The mRNA expression levels of HSP70, HSF1, Bcl-2 and Bax-$\alpha$ at different daily-mean-temperature were analyzed by relative quantitative RTPCR. The DNA content, cell phase and the ratio of apoptosis of lymphocytes in peripheral blood of dairy cattle at different daily-meantemperature were determined by FCM. The PCR-SSCP products of primer pair 1 showed polymorphisms and could be divided into four genotypes: aa, ab, ac, cc, with the cis-acting element (CCAAT box) included. Mutations in the hsp70 5'flanking region (468-752 bp) had different effects on mRNA expression of HSP70, HSF1, Bcl-2 and Bax-$\alpha$. The ac genotypic cows showed higher expressions of HSP70mRNA, HSF1mRNA and Bcl-2mRNA/Bax-$\alpha$mRNA and lower ratio of apoptosis. These mutation sites can be used as molecular genetic markers to assist selection for anti-heat stress cows.

Nausea, vomiting and retching are universal symptoms that affect individuals' state of health and self-care activities of individuals. Accurate measurements of individual symptoms are required to gather more definitive data, and enhance understanding, planning, and implementation of self-care actions. Recently the Rhodes Index of Nausea, Vomiting, and Retching(INVR), a new format of the INV-2(the Rhodes Index of Nausea and Vomiting), was developed to measure the symptoms of nausea, vomiting and retching in an English speaking population. To determine the reliability and validity of the INVR, and the possibility of using the instrument in Korea, the Korean translation of the INVR and the INV-2 were administered to a convenient sample of 105 patients at two University Hospitals in Kwangju, Korea. The Cronbach's alpha to estimate the internal consistency of reliability for INVR was 0.844. Equivalent measures of reliability were conducted to determine the percentage of agreement and the Spearman rank correlation coefficients for responses on the two instruments. The percent agreement was 83% and the correlation coefficient was 0.906 over all. A significant differences between the INVR scores of the patients with and without nausea, vomiting, or retching were seen, which indicated a construct validity. The INVR was found to be more user friendly for the patient and the healthcare providers. As a result, it is suggested that the INVR can provide a scientific base for measuring the symptoms of nausea, vomiting, and retching for nurses to improve patients' care and quality of life.

Purpose: This study was to develop and evaluate the clinical utility of the breast and ovarian cancer genetic counselling program specific for 20 Korean women(KBOCGP). Methods: The KBOCGP was developed using three types of approaches: an ethnography among Korean women who underwent BRCA1/2 test, designing and implementing one week clinical genetic educational course for clinical cancer nurses, educational observation visits to three American cancer genetic counselling programs. And then pre-experimental design was implicated to evaluate the change of the women's knowledge about the hereditary breast and ovarian cancer and the level of the satisfaction with genetic counselling. Results: The mean score of the knowledge has significantly increased from $7.45{\pm}3.86$ to $11.55{\pm}2.21$ (t = 5.63, p < .001). The level of the satisfaction with the counselling was very high ($27.47{\pm}1.35$). Because most of the subjects have young kids, they showed strong concerns about their kids' getting cancer. Conclusion: This new KBOCGP is the satisfactory program for the education and communication of the genetic information to the Korean women with HBOC. But it is needed more to strengthen the cultural sensitivity especially to Korean family relationships. Authors recommend that this program be provided by other nurses who are counselling women at high risk of breast cancer.

The increase in the consumption of outdoors sportswear is not because of an increase in sales from hiking enthusiasts but rather the general public's desire to wear them as everyday clothing. We expect that the market for the outdoors sportswear will grow gradually as people feel the need to wear extra outerwear for protection from wind everyday. Furthermore, as the consumers' demands for these outerwear increase, their desire for more variety increases as well. Five prominent domestic brands were chosen for the analysis. The selection method included two factors: 1) the brands with the highest sales figures in the last five years 2) brands that were mentioned most frequently in fashion articles (i.e apparel news, fashion biz) from 2009 to 2011. the goal is to analyze each of the brands' different concepts of outerwear design so that the results from the analysis can be used to develop better more diverse products in the market and satisfy with the consumers' need. In the end we have to develop better technology and more diverse designs in order to meet the increase in consumers' need. They are interested in sportswear and functional clothing; we have to satisfy their need. for diverse selections in their outerwear and this is especially the case with consumers in their teens and twenties.

Three dominant rocky intertidal macroalgae, the fucoids Fucus gardneri and Pelvetiopsis limitata (Phaeophyta) and the red alga Mazzaella cornucopiae (= Iridaea cornucopiae) on the west coast of Vancouver Island, British Columbia, Canada were used in a series of field experiments to examine interspecific interactions. These experiments showed complex patterns which included an interchange of negative (inhibition) and positive (facilitation) interactions depending on neighbor distance. Less fucoid recruitment occurred in the plots with greater percent cover of a turfforming red alga, M. cornucopiae. However, experimentally removing Mazzaella turf (the turf was considered to be "blocking" fucoid recruits or "shading" growing recruits) did not increase recruitment. This result indicated that there may be another factor(s) involved in the survivorship of juvenile fucoids in the turf-removed plots. Morphological differences in adult plants between Mazzaella and the two fucoids resulted in another type of interaction; these began when fucoids successfully settled and grew nearby or within the red algal turf. By monitoring microhabitat at the individual plant level for two years, I found that survivorship of fucoid recruits showed different species-specific patterns. The patterns also varied as the microhabitat changed from Mazzaella turf edge to open space. For F. gardneri, longevity of P.limitata at all distances tested was similar. A reason for greater longevity of F. gardneri individuals at edge microhabitats may be that these sites have one side open to light and nutrients and another site that buffers them from desiccation and wave impact. In the Mazzaella-Fucus interaction, neighbor distance was a key factor in determining whether the outcome of the interaction would be competition or facilitation (or protection). This study provides experimental evidence that detectable biological interactions occur in this upper intertidal algal community where physical conditions are usually severe, and also indicates the importance of small scale examination in understanding macroalgal interactions in intertidal habitats.
