The purpose of this research was to compare the microtensile bond strength of resin coated surface and resin inlay according temporary filling materials prior to applying self-adhesive resin cement. Caviton(GC, Japan), Provifil(Promedica, Neumunster, Germany), Provifil(Promedica, Neumunster, Germany) & petrolatum, and Eugenol-based cement, Tembond(Kerr, Orange CA, USA) were used as temporary filling materials. After fabrication of Tescera(Bisco, Schamburg IL, USA), it was bonded with a self-adhesive resin cement, Rely X unicem(3M, St. Paul. Minn, USA). After this procedure, the microtensile bond strength was measured and it was analyzed through one-way ANOVA and Duncan test(p<0.05). Caviton(GC, Tokyo, Japan) showed statistical difference except for the control(group I) and the saliva(group II)(p<0.05). Provifil(group IV), Provifil & petroneum(group V), Tembond(group VI) had lower microtensile bond strength.

This study aims to investigate whether geographical variation affects the antibacterial component properties of honeybee (Apis mellifera L.) venom in Korea. Honeybee venom samples were collected from May to September, during 2010 and 2011, from 35 different sites, and were analyzed for major components, including melittin, apamin and phospholipase A2 were determined by a liquid chromatography using ammonium formate, acetonitrile, trifluoracetic acid. On average, melittin, apamin and phospholipase A2 were determined $55.2{\pm}2.07%$, $22.57{\pm}0.103%$, and $12.51{\pm}0.37%$, respectively. The ratio of the major components, including melittin, apamin and phospholipase A2 did not differ significantly according to flower or temperature during collections (One way-ANOVA, Duncan's test (${\alpha}$=0.05)).

This research analyzes the relationship between the height of the sleeve cap and the mobility of arm movement. Ten Korean women participated as subjects. For test clothes, the AH/4+3, AH/4+1, and AH/4-1 height of the sleeve cap were varied. The sleeve circumference was adjusted according to the variation of the height of the sleeve cap. To analyze test clothing objectively, the range-of-motion of two selected movements (Arm Adduction/Abduction and Arm Flexion/Extension) was measured by Leighton flexometer and goniometer. Also, a wearer acceptability rating was examined for acceptance by the subject. Anova and Duncan's multiple range tests are used for statistical analysis. According to the results, the mobility of test clothing 2 and 3 improved 14.9% and 27.7% in Arm Adduction/Abduction, and 12.7% and 31.9% in Arm Flexion/Extension compared to the test clothing 1.

Subjects wee 70 3-, 4- and 5- year old children attending the Y Child Development research institute. Data were analyzed with SPSS using mainly F-test and Duncan's Multiple Range Test. Results showed that among 24 colors used, white, violet, sapphire, sky blue, blue, green yellow, pink, green, red, gold, purple, van dyke brown, blue, green, silver were found to be significantly related to persionality. Judging from this results, white and violet seemed to be most predictive colors to personality.

Purpose: This survey aimed to find out the relationship of work stress, self-efficacy, and task performance of the preceptor. Method: The data of this study were collected from 215 Preceptors who have been working in four hospitals in Deajeon. The data were analyzed by t-test, ANOVA and Duncan test for group differences, Pearson's correlation and Multiple Linear Regression with SPSS WIN 17.0 program. Result: There were significant positive relations between the work stress (r=0.193, p<0.05), self-efficacy (r=0.346, p<0.00), and the task performance of preceptor. The most predictive factors of the task performance were self-efficacy(11.5%), the job stress(2.7%), and age(2.0%). Conclusion: Nursing department supervisors need to manage preceptor to reduce work stress and to improve self-efficacy. It is recommended that work stress should be decreased and programs for increasing self-efficacy need developing in order to satisfy self-realization of preceptors and their needs.
