The purpose of this study was to isolate the observational error included in plane photogrammetric data and suggest more accurate and suitable method for body shape measurement. Three experiments were carried out in this study. First of all, the variables which can be obtained from photogrammetric method were selected among the data which can be measured improperly by direct measurement or showing large deviations between the samples. Secondly, the height, the width and the depth of 50 subjects were measured by plane photogrammetry. The result showed that plane photogrammetric data contain significant observational error even for the same variables, as the angle of which photos had been taken changes. Therefore, in order to reduce the observational error and to measure the human body accurately, three-dimensional measurement, stereo photogrammetry was employed in the last experiment. As it is important to isolateonly the observational error by plane photogrammetry and to exclude the accidental error caused by movement of human body subject, body shape model(manikin) was used as subject. The result showed that the average observational error by plane photogrammetry was more than 4 cm in the height, 0.85-1.29cm in the width and 0.49cm in the depth. In conclusion, it is not adequate to use the height obtained from plane photogrammetric data as human body measurement data. And the width and the depth should be used cautiously, even though they are relatively less significant, the error still can make some difference on clothing construction.

In this study, we suggest a functional coatings to improve the durability and anti-pollution properties of solar cell modules. Anti-pollution functional coating was employed on the glass substrate for the PV module. After coating with a brushing technique on a glass substrate, a hot air fan of approximately 200°C was operated for 2 minutes. Using the method which the coating and annealing process was applied, it was performed 2 ~ 3 times every 5 minute intervals. Samples that completed by all the coating and annealing processes were installed outdoors to conduct the durability testing. In order to investigate the change in durability, characteristics such as light transmittance and contact angle were analyzed. The contact angle confirmed the improved hydrophilic property of glass with the deionized water of 5 μL, resulting in the easy cleaning of the PV module cover glass and light transmittance was surveyed using a UV-visible spectroscopy to analyze changes in its properties according to the outdoor environment.

최근 2등급(DB18)으로 설계된 국도상의 일부 교량들은 교통량 수송능력 향상을 위해 외부후긴장 방법을 적용하여 보강하는 방법이 사용되고 있으나, 그러한 보강 작업의 대부분은 실험 및 해석적 검증없이 사용되고 있다. 본 논문에서는 DB18로 설계된 단순 합성보에 외부 후긴장을 적용하여 보강효과 및 거동을 실험적으로 연구하였으며 실험 결과로부터 외부 후긴장은 극한 및 항복에 대한 강성을 증가시키며 인장파괴 모드로 설계된 구조물의 인장보강에 특히 효과적임을 알 수 있었다. The application of additional post-tensioning tendons has recently been widely considered and requires very little interference with the existing structure. Several bridges on the national roadway designed as the second class were strengthened by external post-tensioning for the capacity enhancement purpose, but much of that strengthening work was not verified analytically as well as experimentally. This paper examines experimentally the behavior of simple composite steel-concrete beams designed as the second class(DB-18) When they are strengthened with external post-tensioning tendon. Test results show that external post-tensioning increases the ultimate load and the magnitude of tendon force increases the yield load but not the ultimate load.
