The film sensor is used for measuring pressure distribution at planar area, especially at a small space or gap. The present paper deals with development of sensors of film type and system for body pressure distribution measuring. The developed system is consist of (1)film sensor with 40*40 array, (2)PCI interface card with maximum sampling rate of 120Hz, and (3)software for data processing and real-time display. A body pressure distribution using vehicle seat experiment revealed that the system successfully measured the body pressure distribution during static and dynamic state. Appropriate contact force of the seat is suggested by this study. The function of body pressure distribution has predominantly performed when the pressure is acted on its surface with human body.

The current thesis, through empirical research, aims to understand the perceptional status of the international cooperation of nuclear safety between Korea and Japan after the Fukushima nuclear accident in 2011. In this context, the thesis also provided some applicable suggestions which could help develop an appropriate international cooperation system and nuclear safety policy. Results showed that there was a marked difference in perception between the Korean and Japanese nuclear power experts regarding international cooperation for nuclear safety. It was confirmed that international cooperation between neighboring countries was ineffective. This is because the countries are not aware of the possible nuclear threats from their neighboring countries, instead they considered it to be a problem for others and not related to their own safety. In particular, there was a very negative perception in Japan of the establishment of regional safety organizations and the setting of common goals and safety standards. The common perception of domestic people was that if the domestic nuclear power plants are safe, there is nothing to worry about the safety and possible threats from the nuclear power plants in the neighboring countries. However, since a nuclear accident in a neighboring country can cause damage to one's own country, international cooperation in nuclear safety among East Asian countries should be promoted.

Recent changes in American and European guidelines on the management of arterial hypertension have caused a considerable shift in the landscape of hypertension management. The 2017 American College of Cardiology/American Heart Association/American Society of Hypertension guideline recommends an office visit blood pressure (BP) > 130/80 mmHg as the new threshold for diagnosis of hypertension, and states that the treatment goal for all hypertensive patients should be lowered to < 130/80 mmHg. In contrast, the 2018 European guideline maintains the diagnostic threshold of hypertension at 140/90 mmHg. However, despite their differences in thresholds for diagnosis of hypertension, both guidelines are in agreement that treatment should be considered in patients with BPs in the range of 130 to 139/80 to 89 mmHg if they have high cardiovascular risk. The results from the Systolic Blood Pressure Intervention Trial (SPRINT) study and recent meta-analyses suggest that BP lowering with antihypertensive treatment may be beneficial in reducing cardiovascular event rates in subjects with high-normal BP or stage 1 hypertension according to the new American guideline. However, intensive BP lowering is associated with increased incidence of treatment-associated adverse events, and evidence suggests that BP lowering below 120/70 mmHg increases the risk of cardiovascular events. In this review, we discuss the evidence supporting antihypertensive treatment in subjects with high-normal BP and discuss the specific subgroup of subjects that might benefit from BP lowering.
