Purpose: This study has examined effectiveness of a secondhand smoking prevention program for adolescents. Methods: The study was done in a nonequivalent control group pretest/posttest design. The subjects of the current study were 198 middle school students from K city in the Gyeongbuk province. The students were assigned to an experimental group (100) and participated in the secondhand smoking prevention program or to a control group (98) and did not take part. Data collection was done from June to July 2012. A Chi-square test, independent t-test, paired t test and ANCOVA were used with the SPSS 18.0 program for data analysis. Results: There were significant differences between the groups in knowledge of short-term influence of secondhand smoking (F=9.65, p<.005), knowledge of long-term influence of secondhand smoking (F=15.53, p<.001), verbal coping skills for secondhand smoking prevention (F=16.35, p<.001), behavioral coping skills for secondhand smoking prevention (F=8.49, p<.005), and assertiveness of secondhand smoking prevention (F=17.30, p<.001) measurements. Conclusion: The secondhand smoking prevention program delivered to the adolescents is an effective method of encouraging secondhand smoking prevention and can be utilized as an effective nursing intervention for adolescents.

Purpose : The purpose of this study was to investigate the effect of posture difference on respiratory function in cerebral palsy patients. Methods : Twenty-two cerebral palsy childrens were recruited this study. Respiratory Function test was measured with Cardio Touch 3000 and Micro Respiratory Pressure Meter. Cardio Touch 3000 was used to assess cerebral palsy childrens' forced vital capacity and forced expiratory volume at one second. Micro Respiratory Pressure Meter was to assess Maximum inspiratory pressure and Maximum expiratory pressure. Subjects had four respiratory functions measured in supine, slouched sitting, and elected sitting postures. Statistical analysis was used Paired t-test for within-group comparisons and Independent t-test for between-group comparisons. SPSS statistics Ver 20.0 was used for statistical anlysis and statistical significance was defined as a p-value less than 0.05. Result : The subjects' respiratory function according to posture showed significant difference in Forced Vital Capacity(FVC), Maximum Expiratory Pressure(MEP) and Maximum inspiratory pressure(MIP)(p<.05). Elected sitting posture had a positive effect on respiratory function than slouched sitting, supine. Conclusion : In conclusion, We could see that change of posture in children with cerebral palsy affects respiratory function and Elected sitting can be a positive help for the respiratory function of children with cerebral palsy.

PURPOSE: The purpose of this study was to investigate the effects of task oriented circuit exercise(TOCE) on the balance and cognition in mild dementia patients. METHODS: The subjects of the study were 30 patients with mild dementia and assigned to the TOCE(task oriented circuit exercise) group(n=15) and aerobic exercise(AE) group(n=15). TOCE group performed six task three times weekly for 12 weeks. AE group underwent the cycle ergometer and treadmill exercise three times a week during the experimental period respectively. Timed up and go test(TUG), Berg balance scale(BBS) and AP1153 Biorescue were used to assess the parameters for the balance. Korean-mini mental state examination and Global deterioration scale(GDS) were used to assess the parameters for the cognition. For the statistical analysis, paired t-test and independent t-test were used to compare the differences among two groups. RESULTS: Each group showed improvement in balance and possibility for improving cognitive function. TOCE group especially, there were significant improvements in limit of stability. CONCLUSION: The results of the study suggest that TOCE is a more diverse exercise programs introduced in the study. Furthermore, TOCE can be a helpful to improve the balance and cognition in mild dementia patients.

An experimental study was performed to investigate the seismic performance of steel reinforced concrete (SRC) special-shaped columns. For this purpose, 17 steel reinforced concrete special-shaped column specimens under low-cyclic reversed load were tested, load process and failure patterns of the specimens with different steel reinforcement were observed. The test results showed that the failure patterns of these columns include shear-diagonal compression failure, shear-bond failure, shear-flexure failure and flexural failure. The failure mechanisms and characteristics of SRC special-shaped columns were also analyzed. For different SRC special-shaped columns, based on the failure characteristics and mechanism observed from the test, formulas for calculating ultimate shear capacity in shear-diagonal compression failure and shear-bond failure under horizontal axis and oblique load were derived. The calculated results were compared with the test results. Both the theoretical analysis and the experimental results showed that, the shear capacity of T, L shaped columns under oblique load are larger than that under horizontal axis load, whereas the shear capacity of +-shaped columns under oblique load are less than that under horizontal axis load.

The paper examined and analyzed the factors affecting TQM in Medical libraries. The questionnaire was used for collecting data and the ANOVA and T-TEST were used for analyzing data. The results showed that librarians positively recognize the need of TQM in Medical libraries. However, the results showed that library system needs to improve the reward system for effective performance of the work. Finally, this study showed that librarians need to be well-qualified person as a professional with the CEO of strong leadership for successful TQM.

The clad sheet material is produced by a roll-bonding process of one or more materials with different properties. Good formability of clad sheet material is an essential property in to deform a clad metal sheet into a part or component. Performance of the clad sheet material largely depends on interfacial bond strength between different materials. In this study, interfacial bond strength of STS/Al clad sheet was analyzed by varying experimental parameters using a blanking process. Experimental parameters are the punching speed, clearance, and stacking order of plate materials. In addition, blanking test results were compared with bond strengths measured by the T-peel test, that analyzes interface bonding strength of the standard clad sheet. The blanking process was analyzed by the finite element method under the sticking condition of interface of different materials, and experimental results and analysis results were compared.

Field piezocone dissipation tests are performed, and the results are compared to the Rowe cell consolidation tests results to investigate the consolidation characteristics of soft marine deposit at the same location in Korea. From these results, statistical formula fur the relation between the coefficients of horizontal consolidation$(c_r)$ from Rowe cell consolidation tests and $t_{50}$ from pore pressure dissipation tests by Piezocone is suggested through the regression analysis. The results are also compared to the existing theoretical formula. It is also shown that suggested formula is similar to Torstensson's(1977) formula based on cylindrical cavity expansion theory and Houlsby and Teh's(1988) formula based on strain path method.

Purpose: The study investigated the knowledge and actual condition of sexuallytransmitted diseases(STD) in Mongoloian. Method: Data from 210 Mongolians were collected for 6days from August 10-15, 2008 using a questionnaire translated by Mongolians to identify the knowledge of STD and with permission, analysis of blood and human immuno deficiency virus(HIV) by SD Bioline Syphilis 3.2 test and SD Bioline HIV-1/2 3.0 test respectively. The data was scored by mean ${\pm}$ standard deviation. Differences were evaluated according to the subjects' general characteristics by t-test and the ANOVA. Results: The average knowledge score concerning STD 48.99(${\pm}.19$) indicated a low level of knowledge. STD was detected in six(2.9%) and HIV was four(1.9%) of the 210 subjects. General characteristics significantly different knowledge level were gender(t=-3.098, p=.002), education(F=6.090, p=.003), type of employment(F=2.443, p=.049), and sexual education experience(F=5.604, p=.004). Conclusion: Education programs to increase STD awareness and its prevention must be developed and regular health evaluations for those already have sexual transmitted disease is needed.
