This study aimed to identify the effects of fashion brand extensions types, preannouncing and consumers' regulatory focus on preference towards extension products. To that end, the study used a 2 (fashion brand extension types: similar vs. non-similar) ${\times}2$ (preannouncing: near preannouncing vs. far preannouncing) ${\times}2$ (regulatory focus: promotion focus vs. prevention focus) three mixed elements. The subjects of the study were 280 men and women in their 20~40s living in Seoul and Chungnam province and total of 229 data were analyzed. Data were analysed with SPSS 19.0 program and three-way ANOVA, simple interaction effects and simple main effects analysis were conducted. The results of this study are as follows: First there were significant differences in preference based on fashion brand extension types and preannouncing. Second, there were significant interaction effects in preference between extension types of fashion brand and regulatory focus. But there was no difference in preference toward extension products according to types of preannouncing and regulatory focus. Lastly, fashion brand extension types, preannouncing and regulatory focus showed significant interaction effects on preference. Thus even in cases of non-similar brand extensions which carry more risk of failing, the appropriate marketing communication strategies such as preannouncing will result in brand preference. Also marketing activities should be comprehensive and strategical based on consumers' tendencies in order to derive positive evaluations.

These days, the importance of the mathematics interaction is strongly emphasized, which leads to the need of research on how the interaction is being practiced in the math class and what can be the desirable interaction in terms of mathematical thinking. To figure out the correlation between the mathematical interaction patterns and mathematical thinking, it also classifies mathematical thinking levels into the phases of recognizing, building-with and constructing. we can say that there are all of three patterns of the mathematics interactions in the class, and although it seems that the funnel pattern is contributing to active interaction between the students and teachers, it has few positive effects regarding mathematical thinking. In other words, what we need is not the frequency of the interaction but the mathematics interaction that improves students' mathematical thinking. Therefore, we can conclude that it is the focus pattern that is desirable mathematics interaction in the class in the view of mathematical thinking.

During an earthquake, soils filter and send out the shaking to the building and simultaneously it has the role of bearing the building vibrations and transmitting them back to the ground. In other words, the ground and the building interact with each other. Hence, soil-structure interaction (SSI) is a key parameter that affects the performance of buildings during the earthquakes and is worth to be taken into consideration. Columns are one of the most crucial elements in RC buildings that play an important role in stability of the building and must be able to dissipate energy under seismic loads. Recent earthquakes showed that formation of plastic hinges in columns is still possible as a result of strong ground motion, despite the application of strong column-weak beam concept, as recommended by various design codes. Energy is dissipated through the plastic deformation of specific zones at the end of a member without affecting the rest of the structure. The formation of a plastic hinge in an RC column in regions that experience inelastic actions depends on the column details as well as soil-structure interaction (SSI). In this paper, 854 different scenarios have been analyzed by inelastic time-history analyses to predict the nonlinear behavior of RC columns considering soil-structure interaction (SSI). The effects of axial load, height over depth ratio, main period of soil and structure as well as different characteristics of earthquakes, are evaluated analytically by finite element methods and the results are compared with corresponding experimental data. Findings from this study provide a simple expression to estimate plastic hinge length of RC columns including soil-structure interaction.

The AMMI (additive main effects and multiplicative interaction) and GGE (genotype main effect and genotype by environment interaction) biplot which were accounted for a substantial part of total sum of square in the analysis of variance suggested to be more appropriate models for explaining G $\times$ E interaction. The grain yield of total ten sesame genotypes was significantly affected by environment which explained 61% of total variation, whereas genotype and genotype x environment interaction (G $\times$ E) were explained 16%, 24% respectively. From the results of experiment, three genotypes Miryang49, Koppoom and Ansan were unstable, whereas other three genotypes Kyeongbuk18, Miryang50 and Kanghuk which were shorter projections to AEA ordinate were relatively stable over the environments. Yangbak which was closeness to the mean yield and short projection of the genotype marker lines was regarded as genotype indicating good performance with stability. Ansan, Miryang48 and Yangbaek showed the best performance in the environments of Naju, Suwon, Iksan and Andong. Similarly, genotype Miyrang47 exhibited the best performance in the environments of Chuncheon and Miryang. Andong is the closest to the ideal environment, and therefore, is the most desirable among eight environments.

Evidences supporting gene-environment interaction are accumulating in terms of environmental exposure including lifestyle factors and related genetic variants. One form of defense mechanism against cancer development involves a series of genes whose role is to metabolize (activation/detoxification) and excrete potentially toxic compounds and to repair subtle mistakes in DNA. The purpose of this article is to provide a brief review of the notion of gene-environment interaction, environmental/occupational carcinogens and related cancers, and previous studies of gene-environment interaction on cancers caused by exposure to carcinogenesis. With a number of studies on the interaction between lifestyle factors (e.g., smoking and diet) and genetic polymorphisms in genes involved in xenobiotic metabolism and DNA repair excluded, only several studies have been conducted on the interactive effects between polymorphisms of CYPs, GSTs, ERCCs, XRCCs and environmental/occupational carcinogens such as vinyl chloride, benzo[a]pyrene, and chloroform on carcinogenesis or genotoxicity. Future studies may need to be conducted with sufficient number of subjects and based on occupational cohorts to provide useful information in terms of advanced risk assessment and regulation of exposure level.

The hydraulic performance analysis of a turbopump with an inducer for a liquid rocket engine was performed using three-dimensional Navier-Stokes equations. A simple mixing-plane method and a full interaction method were used to simulate inducer/impeller interaction. Two methods show almost similar results due to the weak interaction between the inducer and impeller since the inducer outlet blade angle is lather small. But, when the inducer and the impeller are closely spaced near the shroud region, flow angles at the impeller inlet show different results between two methods. Thus, the full interaction method predicts about $2\%$ higher pump performance than the mixing-plane method. And the effects of prewhirl at the impeller inlet are also investigated. As the inlet flow angle is increased, the head rise and the efficiency are decreased. The computational results are compared with measured ones. The computational results at the design point show good agreements with experimental data, however under-predicts the head rise at high mass flow rates compared to the experiment.

Purpose: This study was done to develop a new nursing intervention, Meridian Massage, and to investigate its effect on weight in infants and mother-infant interaction. Method: This study was conducted using a quasi experimental non equivalent control group pretest-posttest design. Thirty-one newborn infants from a postpartum Management Center were selected and assigned to two groups, experimental and control. Data were collected from February 1 to September 30, 2004. Infants in the experimental group (16) were given Meridian massage for 15 minutes daily for 6 days and weighed every day at 10 am. Using the Nursing Child Assessment Feeding Scale(1978), mother-infant interaction was determined before the treatment, after 1 week and 1 month after the massage. Results: Infants in the experimental group had a higher average weight than those in the control group and the difference was significant (Z=-2.29, p=.022). For mother-infant interaction, the experimental group had higher scores tHan the control group, and the difference was significant between both the two groups, and the 3 measurement times. Conclusion: The Meridian Massage in this study showed positive weight gain and positive mother-infant interaction. This study shows that meridian massage is an effective nursing intervention in improving infant development.

The focus of this study was on service recovery process of domestic internet fashion shopping mall, the purposes of this study were to extract perceived interaction effort and service justice with the recovery factors according to service failure by literature review, and to empirically examine the effect this variables on customer satisfaction with complaint handling and loyalty. The questionnaires was administered to 256 internet shopping mall customer, who has experiences of dissatisfaction and complaining behavior after buying fashion products. The data was analyzed by Cronbach's a, confirmatory factor analysis, correlation analysis, and structural equation modeling using LISREL 8.30 program. The results were as follows. First, perceived interaction partly affected serviced justice consumer. Interaction effort on the part of consumer negatively affected interactional justice, but didn't affected distributive justice and procedural justice. However interaction effort on the part of shopping mall positively affected all justice. Second, distributive, procedural and interactive justice positively affected customer satisfaction with complaint handling and loyalty. Finally, customer satisfaction with complaint handling positively affected customer loyalty. The implications of the research and directions for future researchers were discussed.
