This study investigates the effects of the spatial elements of the mulit-purpose commercial complex on visitors' circulation pattern and wayfinding by employing method of space syntax, observation, and interview survey. Two commercial complexes were investigated; Techno-mart represented a vertical type and COEX mall rendered a horizontal one. Analysis of the spatial elements using space-syntax method provided a base line for comparing analyses by the two other methods. Analysis of the interview additionally survey identified the factors affecting wayfinding behavior and contributing satisfaction. The findings suggest that level of the effects of the spatial configuration on visitors' circulation pattern is greater in Techno-mart(vertically oriented) than COEX(horizontally). In COEX, for instance, specific route that connects sub-way station and cinema complex carries far more traffic than main route, even though the main route indicates higher degree of integration of spatial configuration. Similar with observation, the degree of integration is corresponding with the satisfaction and easiness of wayfinding behavior In COEX, specific place and feature seem to have more effects on visitors' wayfinding behavior and circulation pattern than the level of integration of spatial configuration.

Background : There is lack of studies on the effects of the bag-carrying style on the shoulder muscles and body alignment in adults with rounded shoulder posture (RSP). Objective: The purpose of this study was to investigate the effects of various bag-carrying styles on muscle tone, muscle stiffness and spinal alignment in 20 adults with RSP as they were walking on a treadmill. Design : Crossover Study Design. Methods: A subject performed treadmill walking for 15 minutes at a speed of 4 ㎞/ｈ while carrying three different types of bags: a backpack, a cross bag, and a shoulder bag. Results : The results showed that the main effect of timing was observed in the muscle tone for all the variables and in muscle stiffness only for the upper and lower trapezius muscles. As for the main effect of timing, the muscle tone of the upper trapezius and the pectoralis major significantly increased in all conditions, while the muscle tone of the lower trapezius significantly decreased in all conditions. The muscle stiffness of the upper trapezius significantly increased in all conditions, while the muscle stiffness of the lower trapezius significantly decreased in all conditions. As for the spinal alignment, the dimple distance data values significantly decreased for the cross-bag style. Conclusions : This study demonstrated that walking with a heavy bag, regardless of the bag-carrying style, increased muscle stiffness around the shoulders in adults with rounded shoulder posture, and walking with a cross-bag also induced changes in spinal alignment.

The number of people suffering from diabetes have been increased around the world. In this study, we investigated the antidiabetic and antioxidant effects of Anthriscus sylvestris(L.) Hoffm and its main compounds. It was divided into root(R) and aerial part(AP) for comparative analysis. Total polyphenol, total flavonoid content was higher in AP extract, but nodakenin content was higher in R(1169.13 ± 6.00 mg/g) extract. Antioxidant activity was also higher in AP extract. To compare antidiabetic efficacy, we analyzed the effects of R and AP extracts on ɑ-glucosidase inhibition(AGI), dipeptidyl peptidase-4(DPP-4) and protein tyrosine phosphatase(PTP)1B activity. R and AP extracts showed similar effects on AGI and DPP-4 activity in a concentration dependent manner, and there was no effect on PTP1B activation. Glucose uptake(139.51 ± 3.19%) in 3T3-L1 cells was more effective in the AP extract-treated group than the positive control, rosiglitazone, group. Both R and AP extracts were effective in protecting against pancreatic beta cell damage caused by hyperglycemia. These results suggest that Anthriscus sylvestris(L.) Hoffm. could be used as a candidate for diabetes treatment.

Existing reinforced concrete (RC) frame buildings have seismic vulnerabilities because of seismically deficient details. In particular, since cumulative damage caused by successive earthquakes causes serious damage, repair/retrofit rehabilitation studies for successive earthquakes are needed. This study investigates the repair effect of fiber-reinforced polymer jacketing system for the seismically-vulnerable building structures under successive earthquakes. The repair modeling method developed and validated from the previous study was implemented to the building models. Additionally, the main parameters of the FRP jacketing system were selected as the number of FRP layers associated with the confinement effects and the installation location. To define the repair effects of the FRP jacketing system with the main parameters, this study conducted nonlinear time-history analyses for the building structural models with the various repairing scenarios. Based on this investigation, the repair effects of the damaged building structures were significantly affected by the damage levels induced from the mainshocks regardless of the retrofit scenarios.
