  • The purpose of this study is to figure out the effects of advertisements (functional value, sentimental value, self-expressing value) depending on the gender in regard of the attitude towards the advertisement, brand attitude, purchase intention, and the characteristic and quality of the product. From the study on the university students, there was a meaningful interaction among the independent variables in regard of attitude towards advertisement, brand attitude, purchase intention, and characteristic of the product in the four dependent measurements used for the index of advertisement effects. In terms of the attitude towards advertisements, brand attitude, purchase intention, and the characteristic of the product according to the gender and value suggestion, functional convenience was more influential for men compared to the sentimental convenience and self-expressing value. On the other hand, self-expressing value was more influential for women in terms of the advertisement effect and the characteristic of the product. The main effects depending on the gender were common in four dependent values such as attitude towards advertisement, brand attitude, purchase intention and characteristic of the product, and the average of all values was higher from women. Thereby, it can be said that women show more positive advertisement effects in terms of attitude and purchase than men. The main effects on the value suggestion were meaningfully indicated in advertisement attitude, brand attitude, and characteristic of the product except the purchase intention. Also, the functional and self-expressing value made better advertisement effect, while the sentimental value showed a comparatively lower advertisement effect. In terms of the sentimental value, a comparatively low advertisement effect was shown statistically compared to the functional and self-expressing value in all dependent values, but there was no big difference depending on the gender. That is, in terms of the sentimental value, a separate value suggesting advertisement can be more influential when it is combined with the functional value for men, and for women if it is combined with self-expressing value.

  • Unsaturated soil has a possibility to induce a negative pore water pressure. Until now, saturated soil is mainly focused on the research of soil mechanics. Recently, soil mechanics is researched on two major parts such as saturated and unsaturated soil mechanics. Negative pore water pressure has a non-linear relationship with the water content changes. Soil-water characteristic curves of soil in Korea are not determined. There is no proper characteristic value such as air-entry value and residual water content. In this study, the characteristic curves of reclaimed soil, sand, and weathered granite soil were determined by laboratory tests. Air-entry value and residual water content were determined by fitting methods. Soil-water characteristic curves were estimated based on the particle-size distribution and compared with the laboratory test results. The results of soil-water characteristic curves estimation indicated that Fredlund and Wilson's model is excellent for sand and weathered granite soil. Arya and Paris's model is excellent for reclaimed soil.

  • Geotechnical characteristic values for reliability-based design were analyzed using domestic marine clays. Analysis results indicate that there were close to mean values in oder of Student/Ovesen, Schneider and EN 1990's approach. However, it was found that the EN 1990's approach is inappropriate far estimating geotechnical characteristic value due to low reliability of estimation results. Four approaches had a trend of evaluating characteristic value conservatively with increasing of soil variability. Also, stability and settlement of breakwater subjected to nominal stress with unimproved soft grounds were computed to investigate the effects of estimated characteristic values. In case of using the Schneider's approach, the ratio of allowable bearing capacity/acting loads suggested 65% of that obtained from using the arithmetic mean approach, and showed underestimated value of 13.6% of the settlement obtained from the latter. The comparison of case designs using a representative value from arithmetic mean approach with the proposed approaches, using characteristic value showed that the former was mostly overestimated.

  • We address the problem of choosing the most economic mean value for an automatic filling operation on a production line through the sampling inspection. If quality characteristic of a unit is less than inspection specification then the goods is not accepted. Otherwise, it is accepted. The lots that the numbers of non-conforming units in a sample are larger than the allowable number of non-conforming units are rejected. The non-conforming units in the rejected lots are separated by the screening inspection. The non-conforming units separated are sold in discount price. We assume that quality characteristic is larger-the-better characteristic, the distribution of quality characteristic is normal distribution, and the standard deviation of the distribution is known. This paper presents total expected profit function model considering sales revenue, inspection costs, and material costs. The manufacturing process mean value maximizing total expected profit is determined, and the results of the process target value and total expected profit is analyzed as coefficients change.

  • Geotechnical limit state design methods; LRFD of North America is an approach that estimates resistance using design model and then multiplies resistance factor by calculated resistance to reflect the uncertainty of geomaterials and design models; whereas, Eurocode of the Europe employs the partial resistance factor applied directly to each variable in the resistance equation that individual soil properties such as cohesion and angle of internal friction are applied. This discussion paper is a study on characteristic value which has globally been argued through processing of development of Eurocode 7 for geotechnical design even to the present. Estimating the characteristic value of soil properties affects not only determination of design value applied directly to design of geotechnical structures, but also economic feasibility and stability of the structures.

  • For quality improvement, it is important to reduce variations of the quality characteristic. That can be achieved by the a, pp.ication of parameter design methodology to make the performance of the quality characteristic robust over the variety of noise conditions. Taguchi has used the signal-to-noise ratios for that purpose. For the static target characteristic and the dynamic characteristic problem, we propose a reasonable generalized SN ratio and p-value plot for identifying dispersion factors. The orginal idea of the p-value plot in from the gamma-plot in Lunani, Nair & Wasserman(1995). The graphic advantage of the p-value polt for identifying dispersion factors is illustrated through constructed examples.

  • This paper describes a new method for extracting characteristic impedance of transmission line using Substrate Integrated Artificial Dielectric (SIAD). The new procedure to calculate the characteristic impedance of SIAD transmission line is described with the proper equations and basic transmission line theory. The characteristic impedance is determined as an almost fixed value in the proposed method, while it fluctuates according to frequency in the previous method. As the result, the effective dielectric constant of SIAD transmission line is calculated as a fixed value rather than fluctuating one. In order to show the validity of the proposed method, SIAD microstrip lines are simulated and measured, and characteristic impedances and effective dielectric constant are calculated and compared to the previous method.

  • This paper presents the characteristics and effects of grounding resistor and impedance. In grounding system, Grounding resistor is governed neutral currents and voltage. It seems that, grounding resistor has 0 value, then circuit has no faults. While if grounding resistor has large value, then neutral current has large value of fault current and it is made a damage to the utility. In order to analyze the grounding impedance characteristic, EMTP simulation has been used. The grounding impedance characteristic has been analyzed and tested for various grounding arrangements and electrode circuit shapes.
