The purpose of the review article was to summarize and discuss the available information concerning the effect of bleaching on human teeth and reduced treatment on negative influence. Tooth bleaching effect was differ from extent of concentration and application period of a tooth bleaching agent, certainly full knowledge prior treatment about adverse effect possible appearance and follow clinical treatment for the least reduce. It remains unclear in how far those observation may result in significant adverse effect under clinical conditions. Nevertheless, further investigation are necessary to elucidate these aspect more precisely. The findings of the study were as follows : 1. It is recommended to delay placement of restorations after termination of bleaching therapy for at least 1-3 weeks. 2. Reduced negative influence that is clinical feasibility of catalase in protecting bleached surface against Oxygen radical. 3. The residual peroxide in tooth after bleaching seems to be removed by gradual diffusion and it may be possible to eliminate the adverse effect on tooth by using water displacement solution, ethylalcohol and aceton including it for effective removal of free radical oxygen.

A study is presented that examines the effect of personality on preference and purchase intention of positive and negative novelty design products. Participants evaluated their preference and purchase intention on 18 design products including positive and negative novelty design products. A cute Scream character was created as a positive novelty design and a skeleton Mickey character was used as a negative one. We measured extroversion, neuroticism, and visual product aesthetics as individual traits. The results shows that people, of course, prefer(and want to buy) the positive novelty design product to the negative novelty design product. Only in the case of the negative novelty design product, the more neurotic people is, the more they prefer it. Also, among the people who like the negative novelty design product, introvert ones are likely to purchase it but extroverted ones are not. These findings imply that personality plays an important role in liking and purchasing negative novelty design product.

Effect of an accelerated iso-thermal aging (375 degree C x 66days, 375 degree C x 200days) on elastic-plastic fracture resistance curve were examined in SA533B low alloy steel. Fracture toughness test are conducted by unloading compliance method at room temperature. But the apparent negative crack growth phenomenon, usually arise in partial unloading compliance test. The phenomenon of negative crack growth may be eliminated by the offset technique. There is no effect of aging on J sub(IC) and dJ/da in iso-thermal aged (375 degree C x 66 days) specimen, but there is very little effect in iso-thermal aged (375 degree C x 200 days) specimen.

Objectives: The purpose of this study was to investigate a role of self-compassion in conflict resolution strategies among dating couples. Further, we examined conflict resolution strategies as mechanisms to explain in the relationship between self-compassion and relationship satisfaction. Method: Two hundred forty two dating couples were recruited. Actor and Partner Independence Model(APIM) was used to examine actor and partner effects of self-compassion on relationship satisfaction as well as conflict resolution strategies. The total of 4 APIMs, two positive conflict resolution strategies(i.e., positive emotional reactions, active coping) and two negative conflict resolution strategies(i.e., negative emotional reactions and hostility, avoidance) were analyzed. Positive conflict resolution strategies had only actor effect in the link between self-compassion and relationship satisfaction. That is, self-compassionate men and women were more likely to use positive conflict resolution strategies and, in turn, led to their higher relationship satisfaction. Both actor and partner effects were found in the negative conflict resolution strategy models. In terms of actor effect self-compassionate men and women were less likely to use negative conflict resolution strategies and that, in turn, led to their higher relationship satisfaction. In terms of partner effects we found that women's negative emotional reactions and hostility mediated the link between women's self-compassion and their male partners' relationship satisfaction. Men's avoidance mediated the link between men's self-compassion and their female partners' relationship satisfaction.
