An accident involving a boiler can result in a disaster since it handles high-pressurized steam so that it may cause an explosion. Therefore, the boiler is very susceptible to industrial accidents. This thesis aimed to develop counter-plans to prevent industrial accidents involved the boiler. At first after collecting accident cases involving boilers, a survey on the trait of them was carried out. Ant on the other hand a qualitative analysis was conducted to draw out hazardous components in the boiler itself and their inherent relative importance was assessed. Through this procedure, 'negligence of unsafe condition' was noted as the major cause for unsafe acts whereas 'fault in work procedure' for unsafe condition. In the meanwhile, results of a hazard analysis using FMEA technique ranked gas safety devices, a switch preventing gas from under-pressurization, protect relays high. In particular, it was pointed out that the water feeding and steam subsystem has more components in hazard than other subsystems. Considering these analyses results, counter-plans to improve safety management was suggested also.

Flood control and river improvement works are carried out every year for the defense of the flood disaster, it is impossible to avoid the damage when there is a flood exceeding the capacity of hydraulic structures. Therefore, nonstructural counter plans such as the establishment of flood hazard maps, the flood warning systems are essential with structural counter plans. In this study, analysis of the internal inundation effect using rainfall runoff model such as PC-SWMM was applied to Woo Ee experimental stream basin. Also, the design frequency analysis for effects of the external inundation was accomplished by main parameter estimation for conclusive hydraulic routing using HEC-RAS model. Finally, inundated areas for flood hazard map were estimated at Woo Ee downstream basin according to flood frequency using HEC-GeoRAS model linked by Arc View GIS.

Recently, there are many people who live in rural keep getting away from their town. The reason why become aging and reducing society in Rural is weakness of agricultural competition, education, culture and welfare. Thereupon, we need counter plans to make boom in exhaustion rural landscape counter plan, losing consciousness of citizenship, over developing from city planners who are giving serious damage to rural landscape. However, there are many promotions going on to cover weakness of rural. In this research, to set up the right view of rural which considered the different cognitions, it is important to derive each preference or non-preference scenery, and countrified or non countrified scenery. From different cognition, finding preserved and improved factors is necessary to preserve, reform, and improve the countryside scenery. Based on this, to investigate natural characters of viewpoint is providing right direction for future rural landscape.

Due to the lack of a noise and vibration survey for military air bases, noise and vibration are not taken into consideration for new installations, which has resulted in a number of problems, including the separation of tiles. Furthermore, it is not possible to establish appropriate counter-vibration plans to minimize damage resulting from vibration on structures, since no standard is in place when location for residence areas, including military quarters, is determined. In this context, this research includes a noise and vibration survey, on which basis a quantitative evaluation model for vibration of structure by aircraft noise is generated, as well as through linear regression analysis, and suggests installation standards by purpose of structure, minimizing the damage due to noise and vibration, and establishing appropriate counter-vibration plans for future installation and repairs of on-base structures in the military bases.

2001. 9. 11 aviation terror showed us that there are lots of problems in aviation security and we need efficient counter-plans. According to this event, many countries are coming up with various countermeasures. After first hijacking in 1950, the aviation terror is occurring with more various methods until these days. And the scale is bigger than former so they're making much bigger damages. Especially, the case of 9.11 terror attracted people's eye of the world because of enormous casualties and damages. It aroused many people's self-awakening therefore as an important factor the security is given much weight in the aviation safety. In order to keep the step like this tendency and the development of aviation security, beginning with America lots of countries of the world are pursuing diverse aviation security's counter-plans of new side. At this point of time, for our development in aviation industry we should make efficient aviation security countermeasures. In this study, We compared our aviation security activities with major countries after 9.11 terror.

Construction industry is an important key industry and many measures to revitalize it as local economy has been stagnant. However, construction industry works combined with governmental policies, global and local economies, populations, construction companies and many other related factors, and it is very hard for those counter-plans to meet every need and goal of the related. In this study, interviews and questionnaires of the professionals of the construction industry in Busan, were carried out, to find the cause of the inactivity of the construction market, the problems of the policies and regulations, and the problems of the construction companies in Busan and the solutions were suggested. The realistic master-plans and the reduction of the cost price for the problems of the redevelopment business having no feasibility, the reasonable relaxation of the restrictions for the problems of the governmental policies, the professional training and education for the lack of the high-quality human resources and the working system changes for the problems of the local construction companies turned out as results.

In this paper, the result of study on the effectiveness of anti-submarine defense plan according to the disposition of surface ships has been proposed. The surface ship carries a hull mounted sonar(HMS) as a underwater sensor and a torpedo acoustic counter measure(TACM) as a soft-kill weapon against torpedo attacks from the enemy. Nowadays these underwater systems have been combined into a integrated anti-submarine warfare combat system. And in the real anti-submarine operation environment, several surface ships cooperate for executing ASW plans. Considering these ASW systems and the ASW environment, the models of underwater systems mounted on an surface ship and the a general model of anti-submarine defense plan are proposed. And we designed a scenario for conducting simulations to evaluate the ASW plan according to the variation of the range and the relative angle between surface ships and a capital ship. The simulation results show the effectiveness of ASW plan depends on the formation of surface ships and a capital ship.
