As the marine traffic thickens all over the world, the rate of marine casualities is on the increase, Also in Korea the number of the killed and the injured resulting from marine casualities such as ship's collision, increase continuously and the rate of marine casualities in 1992 came to the highest level in the world. The reason of rapid increasing the rte of marine casualities is the mistake of ship's steering in most case. By the way, because the administration of marine traffic is regarded as the belongs of land traffic, the scope of application in laws related to the safety of marine traffic is duplicated or unreasonable. In the view, in case of ship's collision, it is important to know the scope of application in Korean marine traffic laws and to point out the problems companies with them. Therefore, I suggest the improvement of marine traffic laws related to the safety of traffic administration.

The purpose of this study is to confirm whether the fit between the task and the information characteristics makes any effects on the user satisfaction. The task is defined as two sub-constructs representing the degree of exception and analyzability. The information characteristics is divided into the degree of aggregation, scope and timeliness of information. User satisfaction was used as a surrogate measure of the performance of information systems. The computer self-efficacy was used to control any confounding effects. Field research method using questionnaires was employed to empirically investigate the relationship among the variables. Findings of the study are summarized as follows: the fit between the task and the aggregation of information and between the task and the scope of information turned out to have significant effects on information system performance. The implication of such results is that under highly exceptional or less analyzable task environment, less-aggregated or broad information is more appropriate.

The purpose of this research is to write out vulnerability for western area in Jeju island by using drastic method which is the most frequently utilized among the writing techniques of underground water vulnerability. In case of aquifer, it was divided into two types, gravel layer or not and rated. And soil media was rated two kinds of method. Plan 1 is concerned with only soil class and plan 2 is concerned with soil class and gravels (or rocks), Vadose zone was rated differently according to the ratio of gravel layer. In case of plan 1, the scope of drastic index is from the minimum 77 to the maximum 176, on the other hand, plan 2, the scope of drastic index is from the minimum 79 to the maximum 182. In case of using the water quality data of Nitrate from 1994 to 2004, Pearson correlation coefficient are 0.164(Plan 1) and 0.124(Plan 2) and Spearman correlation coefficient are 0.132(Plan 1) and 0.113.

Recently, major public owner and general contractors in Korea are actively preparing and improving BIM manuals and guidelines to effectively apply BIM technology in construction projects. These guideline has a purpose to define the scope of the applying BIM technology to each construction phase and to explain the minimum technology guidance required for the initial stage. In situations where BIM data are to be submitted within a limited time and cost at the design stage, a BIM data preparing process should be carried out in advance to meet the BIM interoperability between the pre and post of construction precess. In this research, we propose the scope of the BIM guidelines to meet and to be considered for the BIM based review of constructability and economic evaluation of Apartment.

In CAI, it is very important to evaluate the grade of understanding which students reach about the scope of problem which students are studying. In this paper, to find out students' learning achievement, we make students reply to test which the system presents and then lead evaluation result using fuzzy number about answer result. Besides, we define the degree of prior knowledge of studentsd as conditioned fuzzy number and use existing fuzzy accuracy production function begore the stage of using fuzzy number, Next, we apply conditioned fuzzy number to accuracy degree of answer produces by this function. Through this, we come to the conclusion that evaluation result as to the same answer result is changed according to the degree of prior knowledge about the scope which students are studying.

This paper is to empirically test scope effects proposed to judge the internal consistency of contingent valuation method. The application was illustrated for the case of estimating people's WTP for improving water quality at Man Kyoung River in the Chon Buk area. The CV survey was carefully designed and implemented by carrying out recommendations from the NOAA Blue Ribbon panel. Using a split sample, we conducted the Cochran-Mantel-Haenszel test with the frequency distribution of no responses, calculated the Turnbull low bound mean for WTP, and measured the mean WTP from estimated variation functions. The test results consistently exhibited that the CV estimates of WTP were adequately responsive to the size of water quality changes being offered. The mean WTP for improving water quality suitable for swimming (5,171 and 5,212 won) was significantly larger than that for agricultural use and fishing activity (3,280 and 3,136 won).
