In this study, we investigated anti-oxidative effects of Duchesnea indica extracts by using Oxygen Radical Absorbance Capacity (ORAC). The extracts were prepared with 0 %, 30 %, 50 %, 70 % and 100 % aqueous ethanol respectively. The 30 % EtOH D. indica extract showed higher ORAC activity than the other extracts. Therefore, we performed in vitro studies on cytotoxicity of NIH-3T3 cells and MMP-8 collagenase inhibition using by the 30 % EtOH extract. The 30 % EtOH extract showed no cytotoxicity and significant inhibition on MMP-8 collagenase. And we performed clinical studies for the anti-wrinkle effect of the Di-Wrinkle Free Cream. The cream formula was prepared with 2 % arbutin and 1 % D. indica extract. Twenty one healthy women volunteers, ages of 35 and 50, applied the cream on their faces twice a day for 8 weeks. The skin was evaluated with PRIMOS (phaseshift rapid in vivo measuring of human skin) system and analyzed by the student's paired t-test. The wrinkles on the eye region were reduced by 13 % based on the PRIMOS system after 8 weeks. In the safety study of the Di-Wrinkle Free Cream, no symptoms were observed such as erythema, edema, scaling, itching, stinging, burning, tightness and prickling by visual observation and medical examination of volunteers for 8 weeks. Moreover, there was no noticeable skin disorder during experience period. These results suggested that D. indica extracts could be applied as cosmeceuticals effective for anti-wrinkle.

Introduction: The aim of the present study was to investigate the effect of mechanical irrigation in combination with mouthwash of antimicrobial agents on salivary bacterial counts. Materials and Methods: This study was performed with a randomized study employing a panel of 40 healthy volunteers (20 males and 20 females) between the age of 26 and 32 years. Volunteers were randomly put in one of four treatment groups. In the first group, 0.2 mL of non-stimulatory saliva was collected from every subjective person. Then, saliva was collected after rinsing with chlorhexidine (CHX) for 1 minute. In the second group, non-stimulatory saliva was collected, and then saliva was collected after rinsing with CHX and irrigation with saline. In the third and fourth groups, the same procedures as the first and second groups were performed with povidone iodine (PVI) instead of CHX. All of these samples were cultured for 48 hours aerobically. The reduction rates of colony-forming units (CFU) were calculated for each group. The reduction rate between each group was tested statistically using student t-test. Results: Using CHX in combination with saline irrigation showed a significant decrease of the salivary bacterial CFU when compared with only using CHX.(P<0.01) And using PVI with saline irrigation showed a little decrease of the CFU when compared with only using PVI, but there was no statistical significance.(P>0.01) Conclusion: It was concluded that the CHX or PVI used with saline irrigation made the salivary bacterial counts reduced more than when CHX or PVI was used alone as an oral antiseptic agent.

By studying the awareness level of students, for the need to protect personal information, and also by studying students' level of perception as to which information needs protection, this study aims to show that increased education is beneficial, and necessary, across all university majors. This increased education is necessary to improve information security, and increase the responsible sharing of private data which has many benefits, specifically in the Healthcare field. Utilizing student volunteers across multiple majors at a university in South Korea. These questionnaires measured the students' awareness of private information, their perception of private information and also the students' experience in receiving university level education regarding private information and the need for its protection. This study shows that, when compared to students in other fields, students in the field of public health had a higher level of awareness regarding the consequences of personal information disclosure for both public purposes and medical research. Within the parameters of this study, this outcome can be explained as the result of exposure to educational curriculum which contained information related to personal information protection. This increased education raised the student's awareness of which information is considered private, as well as, which information is valuable when responsibly shared. As a result, this study shows that an increase in education regarding information privacy, should be included in all university majors, and gives us evidence to support that this additional education is valuable to students at all levels and should be encouraged.

This study collected data of college students' volunteering for maritime and fisheries and found that only few subjects participated in it. They took part in control for release of oil, services for sea village and coastal cleansing. Most were satisfied with their volunteering referring contributing to environment protection, self-fulfillment, social interaction, gaining special experiences and assimilation with nature. The subjects were not satisfied with lack of systematic and effective services, monolithic activities, insufficient publicity, deficient rewards and a shortage of self-capacity. Based upon the research findings, implications for college students' volunteering policies were suggested to promote volunteering for maritime and fisheries.
