Statement of problem: $Periotest^(R)\;and\;Osstell^{TM}$ were known as the most objective and quantitative mobility tests available for evaluating stability of implant in vivo. Although a correlation between PTV widely used and ISQ recently introduced exist, a PTV was corresponded to various ISQ. A correct evaluation of implant stability could be obtained only after one has a thorough understanding of the limitations of devices and factors that affect measurements. Purpose: The purpose of this study was to investigate the causes of variables in the values obtained with these two tests. Material and method: A total of 333 implants 134 $Br{\aa}nemark$, 5 Silhouette and 194 ITI implants were investigated. Result: 1. There was a correlation between PTV and ISQ (Spearman correlation =0.39, p<0.0001) 2. The factors that affected ISQ were diameter of implant future, location of implant and implant system (submerged type vs non-submerged type). 3. The factors that affected W were dimeter of implant future, location of implant, and elapsed time after implant placement. 4. There was no significant difference between different surface treatments of RBM, smooth surface and ti-unite on PTY and ISQ. 5. In radiographic finding, no saucerization or bone resorption has been detected in implants with ISQ values that were above the average level of each PTV. These higher values had higher bone densities around the implant fixture. Saucerization was observed in the most impants with ISQ values that were below the average level of each PTV. Conclusion: There was a correlation between ISQ and PTV. However, each measuring methods had factors influencing the measured values. PTV were less sensitive to marginal bone resorption and influenced with the striking point on an implant to the level of bone. With ISQ, the height of implant from bone level to transducer should be considered.

Objectives: The purpose of this study is to determine the fatigue, self-esteem, and depression of pregnant women with gestational diabetes mellitus (G-DM), and to reveal associated factors of depression. Methods: As a descriptive correlation study, data was collected from 119 pregnant women with G-DM. Data was analysed using t-test, ANOVA, and stepwise multiple regression. Results: Fatigue, self-esteem, and depression averaged $2.09{\pm}.62$ (range of scale 1~4), $2.63{\pm}.32$ (range of scale 1~6), and $0.45{\pm}.25$ (range of scale 0~3), respectively. The depression varied with a statistical significance according to the age (p=.008), employment (p=.014), child (p=.034), and physical and psychological adjustment of pregnancy (p<.001). We also identified fatigue as the most influencing factor and the physical and psychological adjustment of pregnancy as the second most influencing factor, self-esteem as the third, age as the fourth, and child as the influencing factor on the G-DM women's depression. Conclusions: This research provided a valuable opportunity to recognize G-DM as a personal, and societal problem, which calls for relational support as well as personal support. The healthcare providers need to recognize the emotional aspects of the women with G-DM, and make various efforts to promote the physical and psychological health of the G-DM patients.

Gravity ventilators allow the escape of the warm air and air contaminants due to both (either) buoyancy and (or) convection. As a natural ventilation strategy, various gravity ventilators can be installed on the roof. Ventilation efficiency could be affected by various parameters, such as, area of openings, wind velocity and incidence angle, temperature difference between inside and outside, and shape of ventilator. Especially, the shape of roof gravity ventilator might be one of influencing factors for the effective ventilation. The window type gravity ventilators are frequently installed instead of general (standard) gravity ventilator. However, the ventilation efficiencies of them were not proved yet. To compare the ventilation efficiency, general type ventilator and two window type ventilators were numerically tested. Mean age of air, temperature and CO concentration were predicted by using commercial CFD code, AIRPAK (Ver. 2.0) with various conditions. The predicted result showed that general type ventilator is more effective for natural ventilation than window type ventilators.

We investigated grain boundary effect for terrestrial applications of solar cell\ulcorner with low cost, large area, and high efficiency. Grain boundaries are known as potential barriers and recombination centers for the photo-generated charge carriers, which make it difficult to achieve a high efficiency cell. To reduce these effects of grain boundaries, we investigated various influencing factors such as thermal treatments, various grid patterns, selective wet etchings for grain boundaries, buried contact metallizations along grain boundaries, and use of metallic thin films. From the various grid patterns we learned that the series resistance of solar cell reduced open circuit voltage and consequently decreased the cell efficiency. This paper describes the effect of various grid patterns and the employment of metallic thin films for a top electrode.
