The purpose of this study was to examined the effect of cognitive anxiety, physical anxiety, and self-confidence as sub-factory of competitive state anxiety of swimming players on the performance in accordance with sex, carrer, level. The subjects were 179 male and female players at a high school and college level. The results of this study canbe summarized as follows. In case of cognitive anxiety, though there were to significant differences in variable factors by sex, level, players with less carrers showed higher anxiety, and in case of physical anxiety, though there were no significant differences in variable factors by sex, level, players with less careers indicated higher anxiety. In case of self-confidence, though there were no significant differences in variable factors by sex and level, players with more careers higher anxiety.

This study analyze the relationship between competitive condition anxiety and competition power of fifty male high school swimmers and twenty-eight female high school swimmers. As a result, it shows that male swimmers are higher than female swimmers in the field of performance cognitive anxiety. and female swimmers are higher than male swimmers in the field of task result confidence. Swimmers who have high competition power tend to have more task cognitive anxiety than swimmers who have low competition power. However, there is little difference of physical anxiety, confidence, task performance confidence, cognitive confidence by gender and competition power. Although, there is little difference of gender and competition power of high school swimmers, interaction has significant differences in every field.

데이터웨어하우스 개발수명주기상에서 데이터 품질의 평가요소 및 품질향상 방안에 관한 연구

본 연구에서는 데이터웨어하우스 구축시 핵심성공요인인 데이터 품질의 확보방안에 대해 살펴보고 있다. 데이터웨어하우스를 간단하게 말한다면 의사결정을 위해 최적화된 데이터베이스라고 정의할 수 있으며 그래서 많은 조직에서 데이터웨어하우스를 도입하려고 노력하고 있다. 또한 데이터 품질은 데이터 사용자가 사용하기에 적합한 데이터라고 정의할 수 있다. 또한 많은 문헌 및 조사에서 데이터웨어하우스 구축시 고품질의 데이터 확보가 핵심성공요인이라고 주장하고 있다. 본 연구에서는 데이터 품질의 요건으로 접근성, 해석가능성, 유용성, 신뢰성의 4가지 영역으로 나눌 수 있으며 각 영역에는 세부항목들이 있다는 것을 지적하고 있다. 실제로 데이터 품질을 향상시키는 유일한 방법은 데이터의 사용을 지속적으로 증가시키는 방법이다. 만일 조직에서 데이터의 품질 향상을 원한다면 각각의 데이터 요소들에 대해 엄격한 규칙을 적용한 사용이 필요하다. 이러한 고품질의 데이터 확보 위해서는 개발자 뿐만아니라 비즈니스 즉,실제 사용자의 관심과 참여가 무엇보다 중요하다. This paper proposes data quality improvement method for the datawarehouse development. A simple definition of a datawarehouse is : a database that is optimized for decision support. Therefore, now many organizations are trying to introduce it. This paper define "data quality" as data that are fit for use by data consumers. In additon, data quality is critical success factor in the quality literature and survey. The results indicate four dimensions of data quality : accessible, interpretable, useful, believable. Each has measurement items. The only way to truly improve data quality is to increase the use of that data. If an organization wants to improve data quality, it needs to ensure that there is stringent use of each data element. Not only Business staff but also Is department members must involve the datawarehouse development and implementation project to improve data quality.

The numerical simulations in the Weon-Cheon-Ri stream located in a tributary of An-Seong stream were peformed by using the combined models of HEC-1 and DWOPER to understand the water level changes and the characteristics of the propagation of the flood wave subject to the changes in the size and the operating conditions of the hydraulic structure. This hydraulic structure, a weir, has been used for water intake of the agricultural purpose, which is 38m long and 1.5m high. This weir consists of 6 gates with 1.5m wide. In this study a 270mm rainfall event in August 1995 was used to to apply the DWOPER model along the stream reach. The upstream boundary condition at the end of the stream reach was given by the discharge hydrograph derived from the rainfall-runoff analysis, and the water level- discharge relation at the weir was specified as the downstream boundary condition. In this way 4 different simulations were performed by changing downstream boundary conditions which varied with the operating conditions of the gates and the characteristics of the weir. The applicability of the combined models of HEC-1 and DWOPER has not verified at this phase of the research because of the lack of the measured data in the study area. But the implication of the research is that the technique examined in the paper might be useful for guiding the decision making process concerning the gate operation in the small basin during the flooding period.

This paper dealt with FMEA, which is a method of the analysis to secure safety and confidence coming up to customers' expectation in consideration of the environment of the corporation, the industrial environment, and the functional improvement. And by using FMEA, We showed the example analyzed the confidence of the Air Supply System. It was proved by the result of the analysis that the rate of the breakdown which is usually regarded as the first important point to reform can't satisfy the selecting basis to improve. Also the result said that it is not right to depend on only the rate of the failure in making the list of the reform. Through the analysis of the breakdown, FMEA can present the important factors of the reform to improve the confidence of the system. In this study would show the important factors of the improvement in order to product the goods guaranteed confidence through the method of FMEA.

The most common cause of bridge failure stems from floods. The scouring of bridge foundation is the most common cause of flood damsge to bridges. The need to minimize future flood damage to the nation's bridges requires that additional attention be devoted to developing and implementing improved procedures for designing and inspecting bridges for scour. Statistically, we can expect thousands of bridges to experience floods on the order of magnitude of 100-year flood or greater each year. Because it is not economically feasible to construct all bridges to resist all conceivable floods or to install scour countermeasures at all existing bridges to ensure absolute invulnerability from scour damage, some risks of failure may have to be accepted from future floods. However, every bridge over a stream, whether existing or under design, should be assessed as to its vulnerability to floods in order to determine the prudent measure to be taken. The added cost of making a bridge less vulnerable to scour is small when compared to the total cost of a failure which can easily be two or three times the cost of the bridge itself. Moreover, the need to ensure public safety and to minimize the adverse effects resulting from bridge closures requires our best efforts to improve the state-of-practice for designing and maintaining bridge foundation to resist the efforts of scour.

The purpose of this study is to examine GPS data accuracy on traffic behavior analysis and to investigate GPS measurement in the real road condition. This measurement uses GPS hardware and software for collecting speed and position of two model cars at the same time. Data of Disto meter and GPS data which are bases of GPS data value are compared for judging through t-testing and correlation analysis. GPS data is used for calculating car moving distance and speed change. It is useful to traffic control in a city by analyzing basic traffic behavior appeared on leading car and following car.
