Legal permissible limit of herbal drugs metal level in Korea is define 'less 30.0ppm in total(except mineral drugs)' including Pb Hg Cd As Cr Ni etc. This limit has a lot of problems in several factors, that is, not divide hazard and essential elements, not consider high and low toxic effect in each metal, not calculate dose-response relationship and average health behavior in Korean etc. As a that result, It has strong limits and weakness in the basic toxicology and Oriental medicine. To improve and correct these factors, We need to several new approach as like below. It must be radical study following problems in short and middle-long period in the future, toxic metal and essential element must be divide to basic toxicology and also be diverse toxic effect. But mineral drugs that included a amount of severe toxic metals is being used as active prescription drug until now. If toxic, safety and side-effect of metals will be considered, mineral drugs must prohibit instantly or use at least after examined toxic effect. But one of the most important things about herbal drugs contamination, all people and department (government, farmer and trader, oriental medicine doctors and association) will be participate cooperative and collection for preventive or the least contamination in herbal drugs.

Environment-friendly design becomes one of the main issues of the contemporary design. It has been developed with the advent of the organic view of the wend. It started as the environment-protective orientation and then enlarged its boundary including the designs which aims to revive the organic relationship between human and nature. Recent design approach in environment design emphasizes to be 'synchronized with the nature' and its basic attitude is the revival of the right relationship between man and nature. It also can be described as the design for Green Amenity. This paper researches on the concepts, types and the roles of the environmentally-friendly design. There are two basic concepts : one is environment-protective attitude and the other is the attitude which emphasizes the function of Green Amenity. This paper focuses on the latter approach. Through the analysis of the necessity and the function of the environmentally-friendly design, it aims to prove the fact that valuable human life need the design which connects human life aye with natural environment.

Structural pounding due to strong seismic excitations can result in severe damage or even collapse of colliding structures. Many researchers focused on studying the mutual pounding between two adjacent structures while very few researches were concerned with the pounding of a series of structures. This paper aims to study the pounding effect on a series of four buildings having different natural frequencies. The paper also investigates the effect of different arrangements of the four buildings on their pounding response. For this, a mathematical model was constructed using Matlab code where, pounding was modeled using a contact force-based approach. A Non-Linear viscoelastic (Hertzdamp) contact element was used and activated only during the approach period of collision. The mathematical model was validated by comparing its prediction versus experimental results on three adjacent buildings. Then the model was used to study the pounding between four adjacent structures arranged in different sequences according to their natural frequencies. The results revealed that increasing the gap distance generally led to decrease the peak responses of the towers. Such response is somehow different from that predicted earlier by the authors for the case of three adjacent buildings. Moreover, the arrangement of towers has a significant effect on their pounding response. Significant difference between the natural frequencies of adjacent structures increases the pounding forces especially when the more flexible buildings are located at the outer edge of the series. The study points out the need for further researches on buildings in series to gain a better understanding of such complex phenomena.

As we make every effort to improve our health, the needs and interests of the rehabilitation medicine is increasing. And as society gets more advanced and as the quality of life become higher, rehabilitation department will be important for general hospital and we need the certain guidelines about it. In this study, selected 8 general hospitals in the metropolitan area are analyzed by the analysis of drawings and comparison. The important architectural planning of rehabilitation department are the connection with orthopedics and neurosurgery and the position for convenience approach. Rehabilitation department has 0.63~1.07% of general hospital area. And the rehabilitation department is divided into four branches - medical service space, office space, public space and support space. As the number of programs in the rehabilitation department is increasing, the planning will be considered for the flexible use. And this study proposed the programs, necessary spaces, space composition and basic planning of "rehabilitation department".

In a dental treatment, a dentist has to know the possibility to happen all kinds of the emergency and to prepare for managing that situation. Especially, the cardiac arrest is the most serious emergent problem. If the accident were happened, most dentists got embarrassed. The American Heart Association (AHA) is offering the Basic Life Support (BLS), Advanced Cardiopulmonary Life Support (ACLS) and Pediatric Advanced Life Support (PALS) programs for the healthcare who need to prepare the life threatening situation. The PALS is specialized to someone who participate in pediatric health-care field. This program is composed of three major emergency problems, such as respiratory emergencies, shock and cardiac arrests. The main concepts of the PALS are early recognition and systemic team approach. The purpose of this study was to introduce about PALS and to prepare response system for emergencies in the dental environment.

Life-cycle performance analysis of a reinforced concrete box section bridge was generated. Moreover, Monte Carlo simulation with important sampling (IS) was used to simulate the bridge material and load uncertainties. The bridge deterioration model was generated with the basic probabilistic principles and updated according to the measurement data. A genetic algorithm (GA) with the response surface model (RSM) was used to determine the deterioration rate. The importance of health monitoring systems to sustain the bridge to give services economically and reliably and the advantages of fiber-optic sensors for SHM applications were discussed in detail. This study showed that the most effective loss of strength in reinforced concrete box section bridges is corrosion of the reinforcements. Due to reinforcement corrosion, the use of the bridge, which was examined, could not meet the desired strength performance in 25 years, and the need for reinforcement. In addition, it has been determined that long-term health monitoring systems are an essential approach for bridges to provide safe and economical service. Moreover the use of fiber optic sensors has many advantages because of the ability of the sensors to be resistant to environmental conditions and to make sensitive measurements.
