The purpose of this study is to analyze the mediating effect of female university students' perception of dating violence on the dating violence victims behavior. A questionnaire was distributed and collected to a total of 161 female students enrolled in four departments of U University. Frequency and percentage, correlation analysis, simple regression analysis, and hierarchical multiple regression analysis were performed, and the Sobel test was performed to verify the significance of the indirect effects. Findings First, it was found that female university students' perception of dating violence had a negative effect on the behavior of victims of dating violence, and the explanation power was 5%. Second, violence tolerance was found to have a positive effect on the behavior of all dating violence victims, and the explanatory power was 12%. Third, in the first stage, female university students' perception of dating violence significantly explained the tolerance of violence. In step 2, perception of dating violence significantly explained the behavior of dating violence victims, and in step 3, the tolerance of violence explained the behavior of victims of dating violence. When violence tolerance was introduced in step 4, the influence of dating violence perception on the victimization behavior of dating violence decreased, but it was not significant. That is, violence tolerance showed a partial mediating effect in the effect of dating violence perception on dating violence victim behavior. It is necessary to develop and implement practical programs that can raise perception of violence and lower the tolerance for violence to prevent victims of dating violence.

It has already been noted that some tree species, denoted as tolerant species, endure to behavior shadiness in growth than those species, denoted as intolerant species, since this fact of tolerance must be involved in silvicultural practice, the present author, with pinus rigida, pinus Thunbergii, and Buxus koreana, investigated the relation of degree of shadiness to soil moisture condition. Because tolerant and intolerant trees must be considered from the standpoint of their ability to use any of the factors that are likely to be at low concentration in the dense or open forest. The observed results may be summarized as follows : 1. The ability of tolerance of the species to shadiness is differently concluded by the base with which the analysis was made, i.c. Height, growth, diameter growth, T-R ratio or dry matter increase and so on. Regarding this point root collar increment or dry matter increase were considered more reasonable bases for discussing the tolerability. 2. When total length growth, including both stem and root, is taken as standard for the comparison of the ability of tolerance for each species, higher soil moisture condition and thicker shadeniss lessened the ability of pinus rigida, seedlings. Pinus Thunbergii, showed. However more moisture resistant than pinus rigida. Buxus koreana, seemed to have stronger ability of tolerance than any others. 3. When total dry matter content taken as standard, the results obtained are given in Fig, 3. In pinus rigida, the soil moisture supplemented the lack of light.

The purpose of this study was to examine the influence of aesthetic surgery attitude, self-esteem and body image on clothing behavior. Subjects were 356 female college students in Seoul. The data obtained were analyzed by reliability analysis, factor analysis, correlation analysis, stepwise multiple regression analysis and t-test. The major results of this study were as follows: First, five factors of aesthetic surgery attitude were identified: risk tolerance of aesthetic surgery, need of aesthetic surgery, image improvement via aesthetic surgery, keeping the secret of aesthetic surgery, and others' expectation of aesthetic surgery. Second, significant relationships were found between body image and clothing behavior, and self-esteem and body-enhancement of clothing. Also, risk tolerance of aesthetic surgery, need of aesthetic surgery, and image improvement via aesthetic surgery had a significant correlation with clothing behavior. Third, the most important variable which affected the aesthetics and body-enhancement of clothing was body image. The entertainer imitation behavior of clothing was influenced by need of aesthetic surgery, body image, keeping the secret of aesthetic surgery, risk tolerance of aesthetic surgery, and image improvement via aesthetic surgery. Preference for luxury goods of clothing was influenced by need of aesthetic surgery and body image. Body-enhancement of clothing was influenced by body image, image improvement via aesthetic surgery, and self-esteem.

This study examined the linkage between uncertainty tolerance and attitude toward trying business start-up. Uncertainty tolerance can classify by degrees of uncertainty as risk and ambiguity. We examined the effects of risk tolerance and ambiguity tolerance on attitudes toward trying success and failure. And we also examined the effect of attitudes toward trying success and failure on business start-up trying. This study investigated these relationships using 173 under graduate students. The result of analysis indicated that the risk tolerance had positive effects on attitude toward trying failure, but it had not any effect on attitude toward success and process. The ambiguity tolerance has positive effects on attitude toward trying failure and trying process, but it had not any effect on attitude toward success. The attitudes toward trying success, trying failure, and trying process had positive effect on attitude toward business start-up trying. Then results of this study suggests that the uncertainty(risk and ambiguity) tolerance showed a role of antecedent of attitudes toward trying success and failure. Finally, this study concluded with a discussion of the implications of the research findings and directions for future research.

We isolated sixty lactic acid bacteria(LAB) from lactic fermented products. Among 60 isolates of LAB, 30 isolates were identified as Lactobacillus casei ssp.(5 strains), Lactobacillus acidophilus(2 strains), Lactobacillus delbrueckii ssp. bulgaricus(6 strains), Lactobacillus plantarum(4 strains), Streptococcus salivarius ssp. thermophilus(11 strains), and Streptococcus faecalis(2 strains). The acid tolerance and bile resistance of 30 LAB were determined. Because the acid tolerance was affected by the initial cell concentrations, the analysis of covariance could be used to remove the effect of initial cells on acid tolerance when testing for differences in acid tolerance among six species. Viability of LAB under acidic condition, pH 3 for 2 hours at $37^{\circ}C$, was significantly different among the species. L. casei and L. acidophilus strains showed great viability, but L. bulgaricus and S. thermophilus strains were very weak in acid tolerance.

The purpose of this study is to examine the effect of distress tolerance on subjective well-being and the mediating effect of experiential avoidance in the relationship between distress tolerance and subjective well-being. We conducted an online survey a total of 285 normal adults in the nation from October 21 to 24, 2015. The questionnaire was composed of a distress intolerance index, a concise measure of subjective well-being, and acceptance action questionnaire. And questionnaires were distributed and retrived by an online survey company. Collected data has been analyzed by the structural equation modeling. The correlation analysis showed that distress tolerance was positively correlated with subjective well-being, while negatively with experiential avoidance. Also, the verification of mediating effects of experiential avoidance in the relation between distress tolerance and subjective well-being indicated that experiential avoidance partly mediated the relationship at a meaningful level. Additionally, deflection correction bootstrap analysis was used to verify indirect effects and its results revealed that the mediating effect going from distress tolerance to subjective well-being passing through experiential avoidance was statistically significant. That is, distress tolerance not only influences subjective well-being directly but also influences indirectly through experiential avoidance. Finally, significance and limitations of this study were discussed along with the suggestions for further research.

Arabidopsis NDPK2 (AtNDPK2) is a key singaling component that regulate cellular redox state and known to enhance multiple stress tolerance when over-expressed in Arabidopsis plant (Moon et al. 2003). In order to develop transgenic potato plants with enhanced tolerance to multiple stresses, we placed an AtNDPK2 cDNA under the control of a stress-inducible SWPA2 promoter or enhanced CaMV 35S promoter. Transgenic potato plants (cv. Superior and Atlantic) were generated using an Agrobacterium-mediated transformation system and selected on MS medium containing 100 mg/L kanamycin. Genomic Southern blot analysis confirmed the incorporation of AtNDPK2 cDNA into the potato genome. When potato leaf discs were treated with methyl viologen (MV) at 10 $\mu$M, transgenic plants showed higher tolerance to MV than non-transgenic or vector-transformed plants. The NDPK2 transgenic potato plants will be further used for analysis of stress-tolerance to multiple environmental stresses.

In order to develop transgenic potato plants with enhanced tolerance to multiple stress, we constructed the transformation vector expressing both superoxide dismutase and ascorbate peroxidase genes in chloroplasts under the control of a stress-inducible SWPA2 promoter. Transgenic potato plants (cv. Superior and Atlantic) were generated using an Agrobacterium-mediated transformation system. Transgenic potato plants were regenerated on MS medium containing 100mg/L kanamycin. Genomic Southern blot analysis confirmed the incorporation of foreign genes into the potato genome. When potato leaf discs were subjected to methyl viologen (MV) at 10 $\mu$M, transgenic plants showed higher tolerance than non-transgenic or vector-transformed plants. To further study we selected the transgenic plant lines with enhanced tolerance against MV. These plants will be used for further analysis of stress-tolerance to multiple environmental stresses.

Taguchi and VTA(variation Transmission Analysis) methods have been widely used recently as new methods for product design. In this study, Taguchi method using analysis of variance and VTA method using regression analysis are reviewed and compared with each other in terms of parameter design and tolerance design. In analysis of variance, variation of quality characteristics arises from noise factors, therefore the optimal levels of design factors are selected to minimize the effect of noise factors. n regression analysis, variation of quality characteristics arises from variation of each own design factors. As a method to reduce variation of these quality characteristics, sensitivity analysis was performed for each design factors. An example of calculating tolerance interval for the given defect rate in PPM is also introduced. Especially, the new method is suggested to increase the estimation accuracy of variation of quality characteristics through regression analysis.

Progressive addition lenses (PAL) have very wide application in the modern glasses market. The unique progressive surface can make a lens have progressive refractive power, which can meet the human eye's different needs for distance-vision and near-vision. According to the national glasses fabrication standard, the difference between actual optical power after fabrication and nominal design value should be less than 0.1D over the lens effective area. The optical power distribution of PAL is determined directly by the surface. Consequently, the surface processing accuracy requirement is proposed. Beginning from the surface expressions of progressive addition lenses, the relationship equations between the surface sag and optical power distribution are derived. They are demonstrated through tolerance analysis and test of an example progressive addition lens with addition of 2.09D (5.46D-7.55D). The example addition surface is fabricated under given accuracy by a single-point diamond ultra-precision machine. The optical power of the PAL example is tested with a focal-meter after fabrication. The optical power addition difference between test result and design nominal value is 0.09D, which is less than 0.1D. The derived relationship between the surface error and optical power is verified from the PAL example simulation and test result. It can provide theoretical tolerance analysis proof for the PAL surface fabricating process.
