This study aims to investigate the effects of ankle foot orthosis(AFO) on the activities of tibialis anterior(TA), soleus(Sol), rectus femoris(RF) and biceps femoris(BF) during stairs descending. The activities of TA, Sol, RF and BF were initially measured while descending 4 stairs without using AFO. The activities of the same muscles were then measured again while descending 4 stairs while using AFO. Wilcoxon signed-rank tests were used to analyze the results in order to examine the differences between the with using AFO and without using AFO. Although the activities of TA, Sol and RF were relatively lower while using AFO than without using AFO, only the differences in Sol and RF activities were significant(p<0.05). The activity of BF was relatively higher while using AFO compared to the activity of BF observed without using AFO. However, difference was not significant(p>0.05). Conclusion of this study was observed since AFO’s ground reaction force absorption during stairs descending reduced the need to use So and RF that is related to shock absorption. BF activity was increased with AFO than without during standing forward to correct the trunk stability.

Bulguk Temple, one of the national temples, sublimated the high formalism and symbolism into lovely art, and thus be called the pinnacle of Korean architecture. Of many characteristic structures of Bulguk Temple, the stone stereobate and stairs have a great importance in that we can read out the purpose of the architect through their relics. Especially, the stone stairs are noteworthy for they structuralize the intentional space division. The objects of this observation are Yeonwhagyo and Chilbogyo bridges at the entrance of Keungnakjeon precinct, and Cheongwoongyo and Baekwoongyo stairs at the entrance of Daewoongjun precinct. All these relics are the structures that divide the precinct areas on the basis of Buddhist theory and have strong symbolic meanings as well. Although the diverse studies have made on the structures, there are many insufficient aspects for the manifestation of the meanings. In this study, I considered the Buddhist dogmatic meanings of the structures in the formalistic view of the Buddhist architecture. The study was proceeded in the way that the establishments of former studies were fully reflected in it. Through the study, I could confirm that the objects of consideration have the double formalistic meanings and they are strongly structuralizing the symbolism.

Going up and down the stairs is a repeated task in the activities of daily living. These activities are needed during the recovery process with impaired lower limbs. This paper presents the difference of EEI (energy expenditure index) through the slope of stairs. Twenty-one normal young adults took a part in this study (11 males, 10 females). They stepped up and down the stairs which had two different slopes for 5 minutes. Resting heart rate, walking heart rate, and moving distance were recorded. EEI was calculated from the heart rate and moving speed which was calculated by the distance of movement. Data were analyzed by repeated two-way ANOVA with SAS program and the difference of EEI through the slope of stairs was not statistically significant (p=0.9971). The results show that EEI was not affected by the slope of stairs in normal people. But distance of movement (p=0.0067) and speed (p=0.0064) had a significant difference.

Inspection Stairs for bridge is basic facility for inspecting abutment. Based on the surveying for inspection stairs for bridge, basic guidelines for inspection stairs for bridge were proposed.
