In order to design and operate successfully the pressure differential system for smoke control which uses difference of pressure between compartments of building, architectural factors affecting the pressure field of building should be examined and the stack effect is one of the important factors. The field experiments on pressure field in two buildings of 21 stories and 31 stories in summer and winter season with regard to on/off condition of the pressure differential system are carried out to evaluate the influence of stack effect to evacuation and smoke management of high-rise building. In winter season when the stack effect increases, as the pressure differential system starts to operate, the pressure in upper stair rises largely due to the combination effect of the air infiltration from lobby to stair and the stack effect.

Pressure transducers are increasingly used within soil mass or at soil-structure interface for appraisal of stresses acting at point of installation. Calibration of pressure transducers provides a unique relationship between applied pressure and voltage or strain sensed by transducer during various loading conditions and is crucial for proper interpretation of results obtained from pressure transducers. In the present study an in-house calibration device is used to calibrate pressure transducers and the study is divided into two parts: 1) demonstration of developed calibration device for fluid and in-soil calibration of pressure transducers; 2) effect of soil layer thickness on the earth pressure cell (EPC) output. Results obtained from the present study revealed successful performance of the developed calibration device, and significant effect of sand layer thickness on the calibration results. The optimum sand layer thickness is obtained as 1.5 times the diameter of EPC.

By far, studies on the effect of oral administration of peppermint essential oil on blood pressure are not consistent, increasing or decreasing. And the effect of inhalation of peppermint essential oil on blood pressure was not reported. This study was designed to clarify the effect of peppermint essential oil inhalation on the blood pressure and autonomic nervous system. Blood pressure and heart rate variability (HRV) as an indicator of autonomic nervous system activity were measured. The systolic and diastolic blood pressure was not changed significantly by inhalation of peppermint essential oil. Standard deviation of normal to normal (SDNN), a parameter of total activity of autonomic nervous system also was not changed significantly. High frequency (HF) power level, an indicator of parasympathetic nervous system activity was not changed by peppermint. These results indicate that action mechanism of peppermint essential oil on blood pressure is different by the method of administration, oral or inhalation.

This paper investigates leak effect on the outlet pressure at pipeline exit. A modified Weymouth equation(including inclination effect) was used for this study. To investigate leak effect, outlet pressure and ratio of outlet to inlet pressure were compared between no leak and leak conditions for horizontal, upward and downward flows, respectively. Then, effects of leak location as well as leak rate on the outlet pressure were also investigated for all pipeline inclinations.

Objectives : Hypertension is very prevalent disease, and causes serious cardiovascular complications. Nowadays optimal hypertension treatment is emphasized to reduce the incidence of cardiovascular complications. Auricular acupuncture therapy is economical, safe and effective. Its clinical application is various, and it can be used to control blood pressure. So The effect of auricular acupuncture therapy was investigated. Daily variation of blood pressure during needle-embedded period and variation of blood pressure by blood pressure classification were observed. Methods : The auricular acupuncture points we used were Gangapjeom (降壓點), Sinmun (神門), Gyogam (交感), Sim(心), and Icheom (耳尖). Auricular acupuncture needles were embedded for three days. Blood pressure was checked four times per day and the mean obtained. Results : The following results were obtained : 1. During needle-embedded period, systolic and diastolic blood pressure decreased. Blood pressure decreased most significantly 2 days after treatment. 2. The change of blood pressure in the higher blood pressure group was more remarkable than that of the lower blood pressure group. Conclusions : Through this research, auricular acupuncture therapy is considered as an effective and safe method to lower blood pressure.

Artesian pressure exists in Yangsan site, the maximum value of which has been measured as high as 5 t/m$^2$. This paper deals with the prediction of consolidation settlement for the site with artesian pressure. The consolidation settlement at the site has been accelerated using vertical band drains. Since the artesian pressure gives lower effective stress than a static condition, its effect should be considered in the settlement prediction. This case study shows that the prediction of settlement and pore pressure dissipation agrees well with the measurements, when considering the artesian effect.
