PURPOSE. The aim of this study was to evaluate the effect of cyclic loading and screw retightening on reverse torque value (RTV) in external and internal type implants. MATERIALS AND METHODS. Cement-retained abutments were connected with 30 Ncm torque to external and internal type implants. Experimental groups were classified according to implant connection type and retightening/loading protocol. In groups with no retightening, RTV was evaluated after cyclic loading for 100,000 cycles. In groups with retightening, RTV was measured after 3, 10, 100 cycles as well as every 20,000 cycles until 100,000 cycles of loading. RESULTS. Every group showed decreased RTV after cyclic loading. Before and after cyclic loading, external type implants had significantly higher RTVs than internal type implants. In external type implants, retightening did not affect the decrease in RTV. In contrast, retightening 5 times and retightening after 10 cycles of dynamic loading was effective for maintaining RTV in internal type implants. CONCLUSION. Retightening of screws is more effective in internal type implants than external type implants. Retightening of screws is recommended in the early stage of functional loading.

Rapid change of the era has caused change to consumption. New concept of consumer means not consumer who is simply provided a product, but a consumer who lays emphasis on value. That is to say, it indicates a consumer who values both on service and information as well as a product itself when they purchase. Therefore, the purpose of this research is to analyze the changes of POPs and objets at domestic and foreign fashion lingerie shops in different periods, and to encourage the effective introduction of POPs and objets for display at fashion lingerie shops in the future. I have used 100 pictures of 6 domestic brands and 80 of 6 foreign brands to analyze, and the periods were divided into 2000-2003, 2004-2007, and after 2008. The result of analyzing is as follows. First, give much information and great satisfaction to customers through the various types of POP, which convey the image and the concept of the products. If current POP was used only for sales, there ! should be various kinds and types of POPs to present not only basic information of products but also the value beyond it. Second, advance the products value by the presentation of diverse object. Furniture, fixtures, Lighting, Gift Box, Poster and mannequins should be used not to show simple props and presentation of product in the past, but to show brand images and Design concept of products.

This study assessed the quality characteristics of cookies made with different amounts (0, 5, 10, 15%) of black carrot powder. The density and pH value of cookie dough were constant for all groups. Compared to the control group, the moisture content was higher in groups containing the black carrot powder. Increasing the amount of black carrot powder resulted in decreased L-value but increased a-value. Furthermore, the hardness of cookies increased with increasing amounts of black carrot powder. The consumer acceptance test revealed that up to 15% black carrot powder addition was desirable. Total phenol content of the control group was 24.0 mg GAE/100 g, while black carrot powder groups ranged from 45.5 to 103.5 mg GAE/100 g. The DPPH radical scavenging activity was also augmented with increasing volumes of black carrot powder. Taken together, we recommend that cookies with 15% black carrot powder are desirable in terms of overall acceptability and antioxidant activity.

In this study, effects of the V/III ratio on a-plane GaN epitaxial on r-plane grown by HVPE have been investigated. According to increasing of V/III ratio, the value of FWHM of a-plane (11-20) GaN and the value of surface roughness (Ra) were decreased. Growth rate of a-plane GaN epitaxial layer were increased until V/III ratio = 7 as the increasing of V/III ratio, but it was reduced at V/III ratio = 10. At V/III ratio = 10, the FWHM of a-plane (11-20) GaN RC and the surface roughness (Ra) were 829 arcsec and 1.58 nm, respectively, as the lowest value in this study. Also for V/III ratio = 10, cracks under surface or voids were observed the lowest values in images of optical microscope. An M-shaped azimuthal dependence over $360^{\circ}$ angle range was observed for all samples. At V/III ratio = 10, the difference of FWHM of a-plane GaN between $0^{\circ}$ and $90^{\circ}$ was 439 arcsec revealed as the lowest value in the 4 samples.

Purpose: Resonance frequency analysis (RFA) , a non-invasive technique for the clinical measurement of implant stability, was investigated. Peri-implant bony defect may contribute to implant failure. This in vitro study evaluated the resonance frequencies according to various bony defects and determined whether the directional bone defect can affect the value of frequency analysis. Material and Method: Fifteen 3.75 mm in diameter and 10 mm in length, machined self-tapping implant future were used. Twelve types of bone defects that have different horizontal and vertical dimensions were simulated. Embedded implants were attached to the dental surveyor. Then, the transducer was connected with the implant fixture and the ISQ value was measured at four different directions. Two-way analysis of variance and post hoc $Sch\`{e}ffe'$ test were performed at the 95% significance level. Results: The control group showed the highest ISQ value and 5 thread-$360^{\circ}$ group had the lowest one. As the vertical exposure of implants in each angle was increased, the ISQ value was decreased. Although the horizontal exposure in each thread was increased, the ISQ value was not significantly decreased. Conclusion : Although the simulated defect type was different from each other, the ISQ value was similar among groups.
