As the web is vast and disorderly, it is difficult to find desired information on the web. In particular, finding image resources (knowing where and what kind of images can be found on the web) is very difficult but challenging. As the first step towards the web resource mining, this paper reports the preliminary results of collecting a number of images by a web robot as well as presenting those meta information.

The present study examined variables relevant to problem solving in childhood to determine predictive contributions of such variables as parenting style, child's temperament, self-esteem, depression, and self-efficacy. Subjects were 545 2nd, 4th, 6th grade elementary school children and their parents. Data were analyzed with bivariate correlation, multiple regression, and step-wise multiple regression. Results indicated that child's temperament and self-efficacy were significantly correlated with problem-solving, and self-efficacy was the most critical predictor of problem solving.

The purpose of this study was 1) to explain integrated clothing brand loyalty by investigating the dimensions, 2) to investigate relationships between brand loyalty and clothing importance, aesthetic aspects of clothing, modesty, status symbol of clothing and authoritarian personality, 3) to identify the effects of demographic variables on clothing brand loyalty. The subjects were 104 female living in Kyong-Ju, Korea. The data were collected using self -administered questionnaires and analyzed by factor analysis, frequency, correlation, step- wise multiple regression and ANOVA. The results showed that 1) four dimensions of clothing brand loyalty were identified through the factor analysis: continued brand loyalty, habitual brand loyalty, symbolic brand loyalty and committed brand loyalty, 2) the status symbol of clothing, aesthetic aspects of clothing, and authoritarian personality were positively related to brand loyalty. Among these, the status symbol of clothing was the most significant variable, 3) brand loyalty was not varied by demographic variables.

To confirm the effects of binlang(Areca catechu L.) and tansen(Salvia miltriorrhiza bung) on the mutagenicity induced by hydrogen peroxide, SOS Chromotest with Escherichia coli PQ37 and Ames test with Salmonella typhimurium TA104 were perlormed. Methanol-soluble parts of their water extracts showed high inhibitory effect against the mutagenicity of hydrogen peroxide in two bacterial mutation assays. Step-wise fractionation of methanol-soluble part from tansen was done using ethyl acetate, butanol and water. Among these fraction was further partitioned by Sephadex LH-20 column chromtography, and 6 subfractions were obtained. The fraction III showed the strongest inhibitory effects against the mutagenic activities induced by hydrogen peroxide. The inhibition rates of fraction III at concentration of 500$\mu\textrm{g}$/assay were 28%, 30% and 15% against 4-NQO, MNNG and B(a)P, respectively. But the mutagenic potency of AFB1 was increased.

This study aims to develop a potential centrality evaluation model (PCEM) which can evaluate the potential centrality of villages within the catchment boundaries. PCEM is a tool for evaluation of villages\` centralities by the potential centrality index (PCI) developed in this study. For quantification of PCI, total 31 evaluation criteria on the accessibility to other villages and the natural and human environment of the village were introduced. The weighting values of criteria were calculated from the step wise pair-comparision results of 14 specialists in academic fields on rural planning using by AHP (Analytic Hierachy Process) of MCE (multi-criteria evaluation) method. In the results, the weighting values of the spatial accessibility, the natural environments and the human environments were 448, 338 and 214, respectively, among total value being 1,000.

This study proposed a Rural Amenity Values Assessment Model (RAVAM) to evaluate the rural amenity resources based on the Myun as a spatial unit. In RAVAM, 61 rural amenity resources were classified into almost intact nature resources, interaction between nature and man resources, man-made resources, respectively. Especially, Rural Scenic Value Index (RSVI) was developed to quantify rural scenic views as a rural amenity resource. RSVI was utilized in evaluation process of rural amenity resources. The weighing factors for the amenity resources were evaluated from the step wise pair-comparison results of 11 specialists by Analytic Hierarchy Process(AHP). In the results, the weighting values of almost intact nature resources, interaction between nature and man resources, man-made resources were 496, 323 and 181, respectively, among total value being 1,000.

A real tine simulator of running power train for a construction vehicle was developed. The simulator mainly consists of following two parts; (1) running power train part and (2) running load generation part. An optimal servo control algorithm was adopted for designing the multi-variable digital control system of the simulator. By experiments investigating response characteristics under step-wise variation or pre-determined scenario of target vehicle velocity and target load torque, it was verified that the simulator could reproduce physical situations at and actual vehicle with excellent similarity.

The purpose of this study was to quantify the hands of fabrics for the Korean folk clothes using both a KES-FB and an artificial neural network. In order to select the proper input parameters, we calculated the correlation using step-wise regression between mechanical properties and the hand value of fabrics. For the classification, the primary hand values and total hand value, five neural networks with three-layered structure were constructed using the error back propagation algorithm and, in order to reduce errors and to speed up learning, the momentum method was selected. From the analysis of the primary and total hands using a self-constructed artificial intelligence system, the error rates of sleekness, stiffness, silkiness, and roughness compared with the judgement of expert panels were found to be 3.3%, 3.3%, 1.6%, and 4.9%, respectively, while that of the total hand was 9.83%.

The present study examined variables relevant to children's learning-related social skills to determine predictive contributions of such variables as parenting behaviors and parenting competence. Subjects were 130 four and five years old children and their parents. Data were analyzed with mean, standard deviation, t-test, bivariate correlation, multiple regression, and step-wise multiple regression. Results indicated that passionate participation parenting and parenting competence were significantly correlated with children's learning-related social skills, and passionate participation parenting was the most critical predictors of children's learning-related social skills.

Due to the global business environments and severe competitions, SMEs have carried out IS projects for their competitive advantages. However, numerous organizations have faced with difficulties in the IS project management such as large amounts of IT expenses and uncertainties in project implementations. Thus, this study is intended to discover critical risk factors in the IS project management. To achieve this research goal, we have mailed questionnaires to SMEs and SI companies that experienced IS project failures and 63 usual data were collected. The result of analysis with step wise regression showed that 6 factors are related with IS project failures. The study contributes to the literature in two ways. First, this paper empirically identifies IS risk factors for SME manufactures. Second, this research result can be utilized as a checklist for the successful IS implementations. Limitations and future research topics are also discussed.
