정보통신기술이 발달함에 따라 무선 전자상거래가 활성화되고 있으나 이에 대한 정보가 논문, 보고서 등의 자료로 한정되고 있다. 그러나 최근 들어 전자상거래에 있어서 지적재산권의 중요성이 강조되는 시점에서 이에 대한 연구의 필요성이 크게 대두되고 있다. 이에 본 논문에서는 무선 전자상거래와 관련된 기술 동향 및 이에 관련된 지적재산권에 대해 분석하여 국내의 무선 전자상거래에 관련된 지적재산권 확보 방안 및 지적재산권에 대한 대응 방안을 도출하여 차세대 표준에서 지적재산권 확보를 위한 방향을 제시한다.

Materials property data are necessary to secure the reliability of failure prevention techniques such as inspection and remaining life assessment of civil infrastructure and industrial facilities. However, there is no properly collected data in Korea, and those foreign data are hard to use because of the scattering of the sources, the difference of standards, etc. In this paper, materials property database system which has been constructed at Korea Research Institute of Standards and Science is introduced. Constructed database contains 145,000 numeric data of materials property for 600 kinds of metals and can be retrieved on the internet. The database system provides graphical user interface-based information searching functions necessary for the life evaluation and safety analysis.

Researches about micro technology travel lively in these days. Such many researches are concentrated in the field of materials and a process field. But properties of micro materials should be known to give results of research developed into still more. In these various material properties, reliability data such as mechanical, optical, thermal property, etc is the basic property. In this paper, it is measured that is material properties of main BLU(Back Light Unit) components in LCD(Liquid Crystal Display). The pattern shape of prism sheet, diffuser film and reflective plate are measured by variable 3D scanning equipments. It is researched which is the method to measure an optimal 3D pattern shape in each components.

The purposes of this study are to analyze shopmasters' knowledge of apparel merchandise and textile recognition and to investigate the effects of demographic variables on them. Shopmasters' knowledge of apparel merchandise was analyzed on a factor basis. Four factors of apparel merchandise were fashion property, material property, function property and management property. The textile knowledge level of shopmasters was 72.44%. Considering each part of textile knowledge, basic property was 74.69%, comfort 72.17%, management 68.36% and finishing 77.33%. The level of recognition in finishing area was the highest and the level of recognition in management area was the lowest. There were significant differences in the textile knowledge by gender and working period. Female's textile knowledge level was higher. The longer the working period is, the higher the level of textile knowledge is. Shopmasters recognized the finishing area better than university students did. But both of the groups didn't recognize the management area well.

In these days, The base isolation system is often used improve the seismic capacity of the structure Instead of conventional techniques of strengthening the structural members. The purpose of this study is to evaluate dynamic property evaluation of control equipment using Lead Rubber Bearing. In this study, analysis numerical was performed to determine the optimal dynamic property of lead rubber bearing and damper which minimize the response of base from in main control room. Also the analytical results was composed with the test results peformed in previous study

Soil properties are not random values which is represented by mean and standard deviation but show spatial correlation. Especially, soils are highly variable in their properties and rarely homogeneous. Thus, the accuracy and reliability of probabilistic analysis results is decreased when using only one random variable as design parameter. In this paper, to consider spatial variability of soil property, one-dimensional random fields of coefficient of consolidation ($C_v$) were generated based on a Karhunen-Loeve expansion. A Latin hypercube Monte Calro simulation coupled with finite difference method for Terzaghi's one dimensional consolidation theory was then used to probabilistic analysis. The results show that the failure probability is smaller when consider spatial variability of $C_v$ than not considered and the failure probability increased when the autocorrelation distance increased. Thus, the uncertainty of soil can be overestimated when spatial variability of soil property is not considered, and therefore, to perform a more accurate probabilistic analysis, spatial variability of soil property needed to be considered.

Using the net analyte signal, hybrid linear analysis was proposed to predict chemical concentration. In this paper, we select a sample from training set and apply orthogonal signal correction to obtain an improved pseudo unit spectrum for hybrid least analysis. using the mean spectrum of a calibration training set, we first show the calibration by hybrid least analysis is effective to the prediction of not only chemical concentrations but also physical property variables. Then, a pseudo unit spectrum from a training set is also tested with and without orthogonal signal correction. We use two data sets, one including five chemical concentrations and the other including ten physical property variables, to compare the performance of partial least squares and modified hybrid least analysis calibration methods. The results show that the hybrid least analysis with a selected training spectrum instead of well-measured pure spectrum still gives good performances, which is a little better than partial least squares.

The Box-Cox power transformation is generally used for variance stabilization. Recently, Shin and Kang (2001) showed, under the Box-Cox transformation, invariant properties to the original model under the large mean and relatively small variance assumptions in time series analysis. In this paper we obtain some invariant properties in spatial statistics. Spatial statistics, Invariant Property, Variogram, Box-Cox power Transformation.
