  • Purpose: This study was to examine the possibility of the contact with pornographs of elementary school boys and girls and to confirm responses after that, and to compare the feeling of sexual conflict between the boys and girls. Methods: The subjects were 952 5th and 6th graders of elementary school in four city areas(456 boys, 496 girls). Data collection was via questionnaires Results: Except several pupils(34.4% of boys, 27.4% of girls), most of subjects of the study had no contact with pornographs. The response after the contact with pornographs was feeling of shame the most, which was a negative reaction. The sexual conflict appeared more in pupils who had contact with pornographs than in those who had not boys(t=3.84, p<.000), girls(t=3.96, p<.000), which showed a significant difference. However, the conflict between boys and girls was not significant statistically. Conclusion: We would like to suggest that a sound control system must be prepared and a development of programs related to sexual education and promotion of ability fighting against them that can release their impulse of sex.

  • In high-efficiency crystalline silicon solar cells, If high-efficiency solar cells are to be commercialized. It is need to develop superior contact formation method and material that can be inexpensive and simple without degradation of the solar cells ability. For reason of plated metallic contact is not only high metallic purity but also inexpensive manufacture. It is available to apply mass production. Especially, Nickel, Copper and Silver are applied widely in various electronic manufactures as easily formation is available by plating. The metallic contact system of silicon solar cell must have several properties, such as low contact resistance, easy application and good adhesion. Ni is shown to be a suitable barrier to Cu diffusion as well as desirable contact metal to silicon. Nickel monosilicide(NiSi) has been suggested as a suitable silicide due to its lower resistivity, lower sintering temperature and lower layer stress than $TiSi_2$. Copper and Silver can be plated by electro & light-induced plating method. Light-induced plating makes use the photovoltaic effect of solar cell to deposite the metal on the front contact. The cell is immersed into the electrolytic plating bath and irradiated at the front side by light source, which leads to a current density in the front side grid. Electroless plated Ni/ Electro&light-induced plated Cu/ Light-induced plated Ag contact solar cells result in an energy conversion efficiency of 14.68 % on $0.2{\sim}0.6{\Omega}{\cdot}cm,\;20{\times}20mm^2$, CZ(Czochralski) wafer.

  • $TiO_2$ is widely being used as a semiconductor electrode for DSSC. Anti-recombination property and surface area of $TiO_2$ give an important influence to the DSSC efficiency. In this study, $TiO_2$ electrode was fabricated on FTO using screen printing method. Various overlayers were coated on them by dip coating in solution of saturated $Ba(NO_3)_2$, $Mg(NO_3)_2$ and $N_{2}O_{6}Sr$. They reduced the recombination of electrons from photo excited state of Ru dye. The atmospheric plasma treatment was applied to both the $TiO_2$ and each overlayer coated $TiO_2$ surfaces to improve contact ability with dye. We prepared four samples, one sample has bare $TiO_2$ surfaces to improve contact ability with dye. We prepared four samples, one sample has bare $TiO_2$ electrode and the other samples consist of each overlayer coated $TiO_2$ electrodes. We used XRD, FE-SEM, J-V, IPCE and EIS in order to investigate characteristic.

  • We have measured the spectral transmittances of UV blocking soft contact lenses, regular soft contact lenses and regular RGP lenses using the method suggested in ANSI Z80.20 standard. In order to evaluate visible light transmitting and UV blocking characteristics, we have calculated transmittances by integrating over the specific spectral ranges, i.e., visible light, UVA, UVB and UVC. We found that mean transmittances of visible light for all three categories were over 90.0 % which could be considered as within acceptable range for a contact lens. The transmittance of the UVA and UVB radiation for the UV blocking soft lenses except some cases was within UVR (Ultraviolet radiation) transmittance standard. The UV blocking ability of regular soft and RGP lenses was poor as rather expected. These results will be expected to assist clinical opticians and practitioners in utilizing the transmittance characteristics about the contact lens.

  • This study was conducted to identify the factors that influence students' disability acceptance attitudes in elementary schools in face of integrated education becoming common. For this study, a questionnaire survey was conducted on 472 students, from fourth to sixth grade, in three elementary schools in Jeollanam-do; furthermore a regression analysis was conducted using SPSS 23.0. The survey demonstrated that gender and grade did not have a significant effect on disability acceptance attitudes. Whereas empathy abilities, contact and knowledge of children with disabilities, respectively, influenced disability acceptance attitudes. Consequently, improving students' ability to empathize with others is more important than simply providing knowledge in itself. Thus, there is a need for the implementation of programs and education geared toward promoting empathy. Moreover, contact was found to have a negative impact on disability acceptance attitudes, suggesting the need to promote more positive disability-related experiences to elementary school students.

  • This paper proposes a thermal peripheral blood flowmeter integrated with a force sensor that is capable of contact force compensation. We fabricate this blood flowmeter using a nickel RTD (resistance temperature detector) and piezoresistive force sensor by using microfabrication technology. In an experiment, we obtained a decreasing trend for the blood flow under an increasing contact force with a linear tendency of 31.7%/N. We then performed a compensation process based on this obtained trend. As a result, the maximum variance in the blood flow at 1-3N was 9.8%. Thus we achieved consistent blood flow measurement independent of the contact force. In this work, we verified that the thermal blood flowmeter integrated with a force sensor has the ability to accurately measure the blood flow independent of the contact force.

  • This study was designed to demonstrate the ability of Texas Eye Research and Technology Center Dry Eye Questionaire (TERTC-DEQ) to examine the distribution of self-reported dry eye symptoms and their diurnal intensity in university students and compare it with McMonnies & Ho DEQ. Two dry eye questionnaires were administered to 46 contact lens wearers and 47 nonwearers. Contact lens wearers scored higher on the TERTC-DEQ (52.2%) than McMonnies & Ho DEQ (6.5%). Non-contact lens wearers also scored higher on the TERTC-DEQ (19.1%) than McMonnies & Ho DEQ (2.1%). Ocular symptoms worsened with progression of time of day in both groups of subjects. This study suggests that TERTC-DEQ provides a first-choice diagnosis tool to obtain a comprehensive assessment of patient's symptoms, especially in comparison with McMonnies & Ho DEQ. The TERTC-DEQ is an efficient screening survey and may be use in dry eye diagnosis of contact lens-related dry eye.
