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.

신뢰성 설계를 위한 설계변수의 특성치에 대하여 국내 해양토질을 이용하여 연구하였다. 특성치 산정에 대한 연구결과, Student/Ovesen, Schneider 및 EN 1990 방법의 순으로 평균치에 근접한 것으로 나타났고, EN 1990 방법은 지반특성치 산정방법의 신뢰성 차원에서 부적합한 것을 확인하였다. 그리고 제시된 네가지 특성치 산정방법은 토질의 변동성이 커짐에 따라 특성치를 보수적으로 평가하는 경향을 보였다. 또한 이러한 산정된 특성치가 실 설계에 미치는 영향을 파악하기 위하여 방파제에 대하여 임의 하중하에서 미개량 지반의 지지력 및 침하특성을 검토하였다. Schneider 방법을 이용하여 산정한 결과와 토질정수의 산술평균치를 이용한 결과를 비교한 결과, 허용지지력/작용하중비의 경우 전자가 후자의 65%로 나타났고, 침하량의 경우에는 13.6%를 제시하여 과소평가한 결과였다. 그리고 과거 설계사례에서 산술평균치로 결정된 대표치에 의한 것과 본 논문에서 각 지역의 자료로부터 산정한 특성치에 따른 설계결과를 비교한 결과, 산술평균치로 결정된 대표치에 의한 설계는 대부분 과대평가의 결과를 제시하였다.

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.

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.

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.

Purpose - This study examined the relationship between service quality, perceived value, customer satisfaction and behavioral intention of coffee shop using CoffeeSERV scale. In this model, CoffeeSERV scale consists of fundamental characteristics, physical environment, confidence, beverage characteristics, and representation factors. In particular, this study tried to demonstrate the moderating effect of customer's regulatory focus orientation among in the relationships between service quality, perceived value, customer satisfaction and behavioral intention. Research design, data, and methodology - This study intends to expand the existing service quality research by using the coffee shop service quality measurement tool developed by domestic researchers. I wanted to find some implications for the trend. In particular, this study applied the regulatory focus theory to identify individual differences of customers regulatory focusing motivation. In order to verify several hypotheses, the data were 227 college students and analyzed with SPSS/PC 21.0 and SmartPLS 3 program. The moderating role of customer's regulatory focusing motivation was tested using multi-group analysis with SmartPLS 3 program. Results - The resutls are as follows. First, the fundamental characteristic factors only had a significant influence on the utilitarian value perception, but in the hedonic value perception, all other service factors except for the beverage characteristic had a statistically significant effect. Second, utilitarian and hedonic value had significant effects on customer satisfaction. Third, customer satisfaction had a significant effect on behavioral intention. Finally, the regulatory focus orientation played a moderating role in the relationship between beverage characteristic - utilitarian value, representation - utilitarian value, fundamental characteristic - hedonic value, physical environment - hedonic value, confidence - hedonic value, and utilitarian value - behavioral intention. Conclusions - The results of this study show that the various service quality factors that make up the CoffeeSERV scale have different effects on utilitarian and hedonic value. This means that perceived benefits from product and service experience have different impacts on the customer's experience. Therefore, marketers should identify the impacts of service quality dimension that customers who use coffee shops consider important, understand the impact process of these quality factors on experience value, customer satisfaction, and behavioral intention, and allocate limited marketing budget. The results also show that it is possible to establish differentiatied response strategies using customer's regulatory focus orientation to find ways to enhance utlitarian and hedonic value, customer satisfaction, and behavioral intention using various Coffeeshop service quality factors. At the end of this paper, some limitations and future research directions were suggested.
