This study has focused 302 environmental ordinances enacted from 1974 to 2008 by 16 upper-local governments (7 deignated cities and 9 provinces) and the relationships between them and the development of the Korean local autonomy system. The ordinances have been categorized into three types, the voluntary ones without any obligatory stipulations in laws, the optional ones based on laws, and the law based obligatory ones, which have been examined the enactment years and the contents of them. The local ordinances have been enacted in four periods with a few characteristics, which are "the pre-local-autonomy period (1974-1991)", "the introductory-local-autonomy period (1991-1995)", "the local-autonomy-developing period (1995-1999)", and "the mature-local-autonomy period (after 2000)", along the local autonomy development. 57 ordinances were enacted in the first period, 20 enacted in the second period, 46 enacted in the third period and 179 ordinances in the fourth period. The obligatory ordinances were the most in the first period and in the second period, while the voluntary ordinances were enacted most in the third period. 7 designated cities have pretty more ordinances, 160 in all, than 9 provinces, 142. The tendency to enact earlier in the metropolitan area, SeoulCity, IncheonCity and Gyeonggi province, than the others can be seen. It can be said that the establishment of the local autonomy in Korea had accelerated the development of the local environmental management.

Experimental fishing was carried out to compare and analyze catch characteristics of shrimp beam trawl in a fishing area and a non-fishing area during the period of fishing season and off-fishing season in the coastal waters of Geoje. A commercial fishing boat (4.99 tons) was used for the test fishing. The amount of total catches were 14,654g in the fishing area and 12,359g in the non-fishing area, shrimp catches of non-fishing area were much greater than that of the fishing area during the period of off-fishing season (June and August). However, total catches were 27,670g in the fishing area and 33,004g in the non-fishing area, shrimp catches of fishing area were bigger than that of non-fishing area during the period of fishing season (October and December). On the results of the study, catches characteristics between fishing area and non-fishing area showed the reversed results for the period of fishing season and off-fishing season.

Damage to high-rise buildings caused by earthquakes is less frequency due to small distribution of high-rise buildings and low transmissibility of seismic motion to high-rise buildings. However, demand for high-rise buildings is increasing for development of construction technology and efficient land use. In addition, if high-rise buildings are constructed on soft ground such as landfill, transmissibility of seismic motion due to long-periodization of seismic waves is likely to increase. Thus, with development of technology, buildings are required to expand range of seismic design such as safety for long-period seismic waves. Therefore, in this study, dynamic experiments were performed to evaluate response characteristics of high-rise buildings according to period characteristics of seismicwaves and time history analysis was performed to verify them.

In 2000s, the interest of ROHAS has been increased and the environmental problem has begun to be discussed as the environmental and global value, not the individual perspective. And the standard of value for eco-friendly awareness has been expanded to the economic category. The trend of eco-friendly fabric can be divided into 3 periods depending on the property. The period for natural fabric with visual effects(2002~2004) can be summarized as the creation of natural shape using the natural image, the interaction of cotton and the technology from the visual perspective. In the period of functional conjunction with eco-friendliness and technology(2005~2008), the eco-friendly awareness through the conjunction of technology and nature and the re-cycling, and the responsibility to the environment had been increased. In the period of sustainable development for nature and environment(2009~2011), it showed the conjunction with nature and the integration with technology and eco-friendly issues. Therefore, the characteristic of eco-friendly trend in fabric since 2000 can be said; firstly, the high-quality fabric has been developed with technological development for the functional progress. Secondly, the ethical creativity has been displayed with the development and utilization of eco-friendly recycling materials. Thirdly, the materials reflected with eco-friendly issues have emerged.

As for the software development, it is complicated, and size of software is growing larger. And contraction of a software development period is required acutely because it is short a period of software life cycle. Also, it becomes harder development and a maintenance because it is short a life cycle of developed software. According to this an effort is increased in order to reduce a development cost and time as using a component to have been implemented previously in development of software. A current component technology is developing into a very fast speed and is bringing a large change into development of a Web base system in addition to existing software development method. In this paper, we were handling a related technology for Web system development of a CBD base systematically and derived an issue to apply it to development of a Web system and presented an efficient practical use method of a component technology. First of all we looked into a component technology and a CBD methodology systematically and described a component technology in Web. Also, we proposed a method to increase development and efficiency of practical use of a Web system based on a component. The this study result can decrease a development cost of a Web system and a load of maintenance management through the re-use of a code.

Like other major cities in the world, Bangkok and some other cities in Thailand are expanding rapidly. The Office of Transports and Traffic Policy and Planning had selected three cities for a study of urban change; namely, Bangkok Metropolis and vicinity ( including Nontha buri, Samut Prakan , Prathum Thani, Samut Sakhon and Nakhon Pathom), Chiang Mai and Nakhon Nayok. The main objective of the study is to monitor urban development and urban extension as well as the change of landuse from farm land to urban area during two periods by using available satellite data. LANDSAT-5 TM and SPOT-HRV panchromatic were used for the first period and LANDSAT-7 ETM+ and IRS-lD panchromatic were used for the second period with a lapsed time of 14 years. I was found that during this period Bangkok Metropolis and vicinity extended 1,222 square kilometer; Chiang Mai 68.3 square kilometer, Nakhon Nayok 5.97 square kilometer. Most landuse categories which had been changed to urban were rice paddy and mixed orchard. Some suggestion for sound urban development based on satellite data was also included.
