This study proposed a method to analyze the economic benefit of the national map revision program using the replacement cost method. The replacement cost method measures the benefit of a project as the minimum cost to replace functions of the project with those of alternative goods or services in an existing market. Thus, the demands on 1/5,000 topographic map revision in 18 administrative tasks such as city and district management planning were surveyed in three local autonomous entities. Then the cost to alternatively fulfill the demands was estimated with the standard construction estimating system for the field surveying and surveying results in commercial GIS companies for the site investigation. With this cost estimation model, the benefit of the current national map revision program to the local autonomous entities was estimated as 265,960,999 won. And cost benefit ratios according to several revision frequencies from 0.5 to 4 year were also compared to find the optimal frequency.

Under the influence of globalization, South Korea has seen a sharp rise in interracial families. South Korean society faces various difficulties since it has not prepared for the stable settlement of families. Therefore, it is necessary to initiate marital education for the settlement of multi-cultural families in a healthy and democratic way. This researcher has developed a marital education program for multi-cultural families. To reflect the special characteristics, this work required the investigation of multi-cultural families in Gyeongsangbuk-do. The purpose of this work is to improve conjugal relations among multi-cultural families in a formative period of family relations to help those families to settle down early. The program consisted of four steps and 12 sessions. It featured an increase in application flexibility to an actual site by session, and includes a worksheet applicable to an actual site to understand the absence of communication and cultural differences in multi-cultural families during a formative period of family relations. In so doing, it was designed to easily perform nonverbal education. This work is expected to contribute to an improvement in conjugal relations of multi-cultural families in a formative period of family relations and help those families to settle down in a stable way.

A fire and explosion accident caused by a liquefied petroleum gas (LPG) welding and cutting torch gas leak occurred 10 m underground at the site of reinforcement work for bridge columns, killing four people and seriously injuring ten. We conducted a comprehensive investigation into the accident to identify the fundamental causes of the explosion by analyzing the structure of the construction site and the properties of propane, which was the main component of LPG welding and cutting work used at the site. The range between the lower and upper explosion limits of leaking LPG for welding and cutting work was examined using Le Chatelier's formula; the behavior of LPG concentration change, which included dispersion and concentration change, was analyzed using the fire dynamic simulator (FDS). We concluded that the primary cause of the accident was combustible LPG that leaked from a welding and cutting torch and formed a explosion range between the lower and upper limits. When the LPG contacted the flame of the welding and cutting torch, LPG explosion occurred. The LPG explosion power calculation was verified by the blast effect computation program developed by the Department of Defense Explosive Safety Board (DDESB). According to the fire simulation results, we concluded that the welding and cutting torch LPG leak caused the gas explosion. This study is useful for safety management to prevent accidents caused by LPG welding and cutting work at construction sites.

The utility of soil-gas surveys is directly proportional to their accuracy in reflecting and representing changes in the subsurface concentrations of source compounds. Passive soil-gas vapor-phase is merely a fractional trace of the source, so, as a matter of convenience, the units used in reporting detection values from EMFLUX surveys are smaller than those employed for source-compound concentrations. According to the Leaking Underground Storage Tank(LUST) Program Annual Report, approximately 16 U.S. million dollars were spent for environmental site investigations at over 1,600 Underground Storage Tank(UST) sites and approximately over 1,000 acres of land was characterized and remediated in the State of Illinois in the year of 2003 alone. The main purpose of this study is to propose an idea to significantly reduce the site investigation cost by utilizing a passive soil-gas survey and conventional intrusive drilling method and to fully define the three dimensional characteristics of subsurface contamination from two industrial drycleaning facilities.

It has been said from previous studies that the preconsolidation pressure (p$\sub$c/)of Nangton Rive. deposit is considerably less than the in situ effective burden pressure (p'$\sub$$\upsilon$ο/). Question has risen whether this small pc vale is due to under consolidation or unsuitable laboratory test including low small quality. As a cooperative research program between PHRI (Port and Harbor Research Institute) and Pusan National University, an extensive soil investigation was carried out at a site of Yangsan, Pusan, using the Japanese sampler. It Is found that although p$\sub$c/ value at the site is slightly greater than p'$\sub$$\upsilon$ο/, its over consolidation ratio (OCR) is quite small compared with aged normally consolidated clay in Japan.
