2007년 6월 14일, OPRC-HNS 의정서의 발효로 해양에서 대형 위험 유해물질(HNS) 오염사고발생시 범국가적 차원에서 신속하고 효율적으로 대응할 수 있는 사고대응체제 구축이 필요하게 되었다. 이에 따라 이미 화학물질에 대한 긴급계획을 수립하여 운영하고 있는 미국에서의 화학물질 해양오염사고에 대한 재난관리 사고대응체제 등 국가방제체제의 특성을 분석하였다. 미국의 국가방제체제에는 단일화된 신고 접수체계와 통합된 사고지휘시스템을 운용하고, 재난대응기관간 원활한 협력을 위한 공동책임제 등의 주요 특징을 가지고 있다. 또한 방제작업은 중소사고의 경우 정부관리 아래서 민간주도로 이루어지나 대규모 사고 등 재난적 규모가 예상되거나 발생시에는 정부 주도로 대응하며 이에 대한 경비는 별도 기금(Superfund)으로 운용 보전하고 있다. 이러한 특징을 바탕으로 국내 실정에 맞는 관련법 정비를 통해 육상 사고기관과의 장비, 인력 및 기술 협력체제를 구축하고, 방제조치의 민간참여 활성화 및 방제지휘체계의 일원화 등을 제시하였다.

The disaster preparedness system in Korea has been developed in spite of many obstacles, but there are still many problems for response to various kinds of disasters in 21th century. Disaster response system in Korea was focused on policy, administration, hardwares in the past. But in the future it is necessary to change the system to adapt the global needs about the human based disaster response system and capacity to assist the international disaster by official assistance and research for that field. Because nearly all the disasters are associated with the safety, welfare, injury, disability and survival of human, health disaster preparedness and response system should be a important part in the whole disaster system considering the common value of human right to disaster preparedness for human.

Recently, the concept of an outrigger damper system with a damper added to the existing outrigger system has been developed and applied for dynamic response control of high-rise buildings. However, the study on the structural characteristics and design method of Outrigger damper system is in the early stages. In this study, a 50 story high - rise building was designed and an outrigger damper system with viscoelastic damper was applied for wind response control. The time history analysis was performed by using the kaimal spectrum to create an artificial wind load for a total of 1,000 seconds at 0.1 second intervals. Analysis of the top horizontal maximum displacement response and acceleration response shows that outrigger damper systems are up to 28.33% and 49.26% more effective than conventional outrigger systems, respectively. Also, it is confirmed that the increase of damping ratio of dampers is effective for dynamic response control. However, since increasing the damping capacity increases the economic burden, it is necessary to select the appropriate stiffness and damping value of the outrigger damper system.

In this paper, we present optimization technique for the response time of DVR (Dynamic Voltage Restorer) and the possible compensation range of voltage dip by the DVR system. To protect 3-phase phase-controlled rectifier from voltage dip, DVR system needs to have optimum response time as an important design factor. Although the fast response time of DVR ensures wider range of voltage dip, DVR controller has so high cost and poor stability. This paper proposes DVR system with optimum response time required for certain intensity of voltage dips and good stability to support possible compensation range of voltage dip. Proposed technique showed optimum response time and good stability for overall system. We believe that proposed technique is reliable and useful in DVR design.

The purpose of this study was to test the discriminant analysis model of Quick Response system and to examine the detailed relationship between each discriminant factor and Quick Response adoption. In this discriminant analysis model of Quick Response system, firm size, strategic type, product category, fashion trend, selling time and the Quick Response benefits were included as discriminant factors. Onehundred and two subjects were randomly selected for the survey study and discriminant analysis, descriptive analysis, t-test, and x square test were used for the data analysis. The results of this study were: 1. Wilks Lambda and F value support the discriminant analysis model that, taken together firm size, strategic type, product category, fashion trend, selling time and the Quick Response benefits significantly help to explain Quick Response adoption. 2. The importance of discriminant ability was, in order, firm size, the Quick Response benefits, women's wear, fashion trend, analyzer, selling time, reactor, defender and men's wear. 3. The discriminant function had the high hit ratio, so this can be well used for the classification of Quick Response adoption/nonadoption.

The frequency response of a electro-hydraulic servo(EHS) system is studied. The frequensy response characteristics of the EHS system obtained by linerization method, nonlinerar simulation method, and experimentation are compared ane another. It is found that the frequency response of the EHS is consistent when input signal applied is very small, but that is deviated as input signal becomes large.

Electro-pneumatic valve is an electro-mechanical device which converts electric signal into pneumatic flow mu or pressure. A measurement of dynamic response time is very important to evaluate valve performance. Dynamic response time of electro-pneumatic valve has a variation accordance with valve types, operating way and test standard. In this study, automatic measurement system of dynamic response time is composed based on test condition of dynamic response time test standard(CETOP, JIS). Also, in this study test pressure variation characteristics accordance with variation of solenoid excitation power, and we developed dynamic response measurement system enable to compare of and analyze these two characteristics.

In this paper we develop the web-based unified randomized response system for obtaining more reliable response to the sensitive characteristic such as a crime of violence at home, and a bribing and so on. This survey system embody to apply with from the classical to recently research, for example from the Warner's model to the 2-stage model. In addition, our survey system is able to link between the typical and the randomized response system. Finally, our survey system looks into a variation according to various sensitive questions as well as it can be used for a single question.
