Background: Human papilloma virus (HPV) occurs in women of all age groups, and causes cervical, anal, vaginal, vulvar, penile and oropharyngeal cancers. The aim of the study was to discover what nurses know about HPV infection, testing and vaccination and to determine vaccine practice of their daughters and perceived barriers. Materials and Methods: This cross-sectional and prospective study was carried out nurses who have worked in a hospital between January and June 2014. Pre-test and post-test were used to evaluate the nurses' knowledge about HPV infection, testing and vaccination. This study was performed with nurses who had girls between 9 and 26 years of age for evaluating the behavior of vaccination after three months of education. Results: The mean of pre-test and post-test scores about HPV infection, which included 22 items, were $8.2{\pm}5.6$ and $19.2{\pm}1.5$, respectively. Before education the HPV testing knowledge score was remarkably poor ($1.9{\pm}1.7$ over 5), after education it increased to $4.8{\pm}0.5$. The mean HPV vaccine knowledge score were $3.7{\pm}2.7$ (pre-test) $7.3{\pm}0.8$ (post-test) on a 0-8 scale. The difference between mean total pre-test ($13.9{\pm}9.1$) and post-test ($31.3{\pm}1.9$) scores was statistically significant (p<0.001). After three months of education, only two of the nurses' daughters were vaccinated. The main reason was noted by nurses were not willing to be vaccinated was cost, doubts about safety and efficacy related to the vaccine. About one-third of nurses declared that they would receive the vaccine for their daughter later. Conclusions: Nurses have a crucial role in the prevention, treatment, increasing public awareness and care for population. The education of the nurses about HPV infection, test and vaccination will play an important part decreasing cancer mortality and morbidity.

This study was conducted to effect the cell activity and cytotoxicity of dentifrice. For the study, 6 kinds of general dentifrice, 3 kind of whitening dentifrice, 2 kinds of natural dentifrice and SLS(sodium lauryl sulfate) of positive control group. Immortalized human gingiva fibroblast cell was used for the study, WST test for cell activity and Agar diffusion test for cytotoxicity. Agar diffusion test showed high cytotoxicity in general dentifrice test group and whitening dentifrice test group, but low cytotoxicity in natural dentifrice test group. As a result of cell nucleus staining, cell shape and nuclear activity showed that the highest activity in natural dentifrice group, followed by whitening dentifrice group and general dentifrice group. As a result of this study, the cytotoxicity of different ingredient and according to the use to dentifrice. As a result of this study, we confirm cytotoxicity of kind and components according to the purpose of using dentifrice. Therefore, it is necessary to indicate the detailed ingredients of dentifrice for the smart choice of consumers.

The uncanny valley is a hypothesis about robotics concerning the emotional response of humans to robots and other non-human entities. Although it stands today as one of the robots and synthetic characters, the uncanny valley was speculative and few studies have been performed to test the theory. In two experiments, a total of 183 participants were employed to explore this hypothesis. The results of experiment 1 indicate that the perceived human likeness of a robot is not a key factor causing uncanny valley. And the results of experiments 2 suggest that even if the appearance and motion of a robot become fully human, the emotional response of humans could not reach human-human empathy levels.

The purpose of this study was to identify the knowledge level of human papilloma virus and performance of anti-cervical cancer vaccine among health college student in Korea. A quantitative, descriptive design was used to study 471 students in Ulsan, recruited from April 1 to May 30, 2011. The data were analyzed SPSS program, using descriptive statistics, t-test and ANOVA. The percentage of the participants who received HPV vaccination was 4.0%. The average level of health belief and knowledge about human papilloma virus were 3.05, 5.01 points. Therefore, it is needed to reduce HPV infection through concrete educational programs and advertisement. Also, this educational programs need to include strategies the knowledge of human papilloma virus.

This paper described the effect of subjective approach in case of the human sensibility experiments. The procedure is proceeded subjectively. Human faces are selected as the image presentation media. Pleasant and unpleasant images are selected directly by examiner, And also the image presentation system, which is executed with a computer and has the square-type black box monitor equipment, is manufactured. Images are presented with the step-variation time interval technique. questionnaire test and EEG signal detection data are analyzed. The analysis parameters are a “frequency band integral value” and a “band differential variation ratio”. he results show the high sensibility and fast response. The fact that image presenting repetition alleviates is verified.

This paper introduced a measurement method for image sticking based on human vision perception. Existing image sticking quantification method is mostly different from visible level by human perception. It takes a long time to measure image sticking which is degraded by time due to using a spot photometer, therefore many test samples could not be evaluated in a given short period of time in mass production line. However, the new measurement method in this paper is possible to evaluate a large quantity of samples in fast and high correlation with human perceptual level of image sticking.

This study deals with the investigation of recognition structure on architectural environment and reconstruction of it by artificial intelligence. To test the possibility of the reconstruction, recognition structure on architectural environment is analysed and each steps of the structure are matched with computational methods. Edge Detection and Neural Network were selected as matching methods to each steps of recognition process. Visual perception system established by selected methods is trained and tested, and the result of the system is compared with that of experiment of human. Assuming that the artificial system resembles the process of human recognition on architectural environment, does the system give similar response of human? The result shows that it is possible to establish artificial visual perception system giving similar response with that of human when it models after the recognition structure and process of human.

To improve antithrombogenicity of polymer that used in vascular graft and artificial organs, seeding of human endothelial cells on the polyurethane was studied. Human endothelial cells were ismlated from human umbilical veins, using type I collagenase, and identified with goat anti vWF antibodies. Human endothilial cell seeding was tried upon the polyurethane which has good mechanical property and resists stresses. The hydrophobic polyurethane surface was changed hydrophilic by corona discharf:e treatment. Surface hydrophilicity was measured with Wilhemly plate method and the goniometer. To evaluate matrix protein adsorption, fibronectin adsorption test was done. To eveluate cell adhesion, human endothelial cell attachment forces were measured rising a perfusion chamber of , ism diamter. Less cells were detached from the hydrophilically treated polyurethane. This showed that corona discharge on the polyurethane could improve matrix adsorption and endothelial cell attachment.

This paper deals with a tangible interface system that introduces robot as remote avatar. It is focused on a new method which makes a robot imitate human arm motions captured from a remote space. Our method is functionally divided into two parts: capturing human motion and adapting it to robot. In the capturing part, we especially propose a modified potential function of metaballs for the real-time performance and high accuracy. In the adapting part, we suggest a geometric scaling method for solving the structural difference between a human and a robot. With our method, we have implemented a tangible interface and showed its speed and accuracy test.
