DNA has not been played the role as a biocatalyst in evolutionary history, although RNA and protein function as a biocatalyst. DNA double helix structure is believed to be impossible to form intricate active enzymatic sites. In addition, the chemical stability of DNA prevents the ability from self-modifying reactions. However, recent development of DNA engineering enables to create artificial enzymatic ability of DNA (deoxyribozyme) such as RNA cleavage and DNA modification. We investigated optimal conditions for enzymatic activity of DNA-Pt complex, and compared it with that of horse radish peroxidase. We report here that base sequence of DNA, pH and temperature affect the enzymatic activity of DNA-Pt complex.

Purpose: The purpose of this study was to identify the influence of cell phone addiction on communication skills and the interpersonal relationship ability of adolescents. Methods: The researcher recruited 751 high school students to assess their general characteristics, communication skills, cell phone addiction and interpersonal relationship ability. Data were collected from June 30 to July 14 in 2014 using copies of a structured self report questionnaire. The collected data were analyzed with descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and linear multiple regression using the SPSS/WIN 21.0 IBM program. Results: Of the students, 3.5% reported they were addicted users, and 7.6% reported they were heavy users. Results from multiple regression analysis showed that cell phone addiction did not have any influence on communication skills of the adolescents. However, cell phone addiction mostly affected the interpersonal relationship ability of the adolescents (${\beta}=.24$, p<.001). Poor school performance (${\beta}=.17$, p<.001) and low socioeconomic status (${\beta}=.12$, p<.05) were also related to the interpersonal skills of the adolescents. These variables explained 8.3% of the variance in the interpersonal skills of the adolescents. Conclusion: These results suggest that cell phone addiction has a negative influence on the development of the interpersonal relationship ability of adolescents. The findings of this study are expected to provide basic data about the influence of cell phone addiction on the interpersonal relationship ability of adolescents. Therefore, cell phone addiction treatment programs for adolescents need to include contents related to interpersonal relationship ability.

Objectives: The purpose of this study was to examine the knowledge of dental hygienists on CPR, their CPR attitude and performance ability in an effort to offer data that can contribute to the development of a more effective CPR education program. Methods: A self-reported questionnaire was filled out by 234 dental hygienists in Jeollanam and Jeollabukdo from February 24 to May 20, 2017. The questionnaire asked dental hygienists of the knowledge, attitude, performance ability in regards to CPR. The data were analyzed using SPSS Window ver. 19.0 program through independent t-test, one-way ANOVA, chi-square test and multiple regression analysis. The Cronbach alpha of their CPR knowledge was 0.78, and that of attitude to CPR was 0.79. The Cronbach alpha of CPR performance ability was 0.96. Results: The dental hygienists surveyed in this study who were aware of CPR accounted for 88.9% of total subjects. Dental hygienists who were certified in CPR accounted for 20.5% of total subjects. They received a score of 7.66 on CPR knowledge, 3.33 on attitude and 2.61 on performance ability. There was a positive correlation between the knowledge and attitude, between the knowledge and performance ability and between the attitude and performance ability (r=0.332, r=0.461, r=0.426). A regression analysis showed that the dental hygienists who were younger, who graduated from a four-year university or a higher educational institution, who were CPR certificate holders, who received more CPR education, who were cognizant of automated external defibrillator, who were more knowledgeable on CPR and who took a more positive attitude were more likely to be affected in terms of CPR performance. Conclusions: The dental hygienists surveyed were aware of CPR on the whole, but their CPR knowledge, attitude and performance were not sufficient to perform CPR in emergency situations. More intensive education should be provided for dental hygienists to have an accurate knowledge of CPR to carry it out with a positive attitude.

The purpose of this study is to analyze the state of father’s role performance and self-esteem of adolescents, to investigate the relation between the father’s role performances recognized by adolescents and the self-esteem of adolescents, and to present the basic data for showing the importance of father’s role in increasing the adolescents’self-esteem. The subject of this survey was 795 male and female students of the second grade in Kwangju middle and high schools. The questionnaire was used for this study as a means of measuring. The results of this study were as follows：1. The degrees of father’s role performances were considered ‘82.19 points’out of 125 by adolescents but rather high by the female students, it didn’t have any significant difference between the male students and female. 2. The degrees of adolescents’ self-esteem were ‘51.17 points’out of 85 on the whole. But specifically, the degrees of adolescents’self-esteem of the male students were higher than those of the female students. This self-esteem of adolescents caused significant differences in the right to the decision-making and the father’s occupation only. 3. The influence of father’s role performances on the adolescents’self-esteem was found very high, and more influence were showed by the female students than by the male students. 4. The order in the effective poser of variables on the adolescents’self-esteem was as following； the role in command and harmony, the sex, the economic role, the role in intellectual ability development. In conclusion, father’s role performance were found to be important variables on the conform adolescents’self-esteem.

This experimental study deals with the mechanism of spoilers that cause scouring around pipelines. The design methodology was applied to spoilers for accelerating pipelines that undergo self-burial into the sand-bed and evaluated using approaching experimental analysis. The experimental study was conducted to investigate the self-burial ability of submarine pipelines with two types of sand-bed models: silt and sand. Spoilers of different heights were attached to the top of the pipeline for each experiment case. The relationship between the relative scour depth and spoiler height was evaluated by applying different flow velocities and sand diameters and comparative analysis was performed with values obtained from similarity experiments and theory. The experimental study will be useful in establishing a database for the design of spoilers.
