The strength reduction factor spectrum is traditionally obtained from a single-degree-of-freedom (SDOF) system with a constant damping coefficient. However, according to the principle of Rayleigh damping, the damping coefficient matrix of a system changes with the stiffness matrix, and the damping coefficient of an equivalent SDOF system changes with the tangent stiffness coefficient. In view of that, this study proposes an equivalent SDOF system with an adaptive damping coefficient and derives a standardized reaction balance equation. By iteratively adjusting the strength reduction factor, the corresponding spectrum with an equivalent ductility factor is obtained. In addition, the ratio between the strength reduction factor that considers adaptive damping and the traditional strength reduction factor, denoted by η, is determined, and the η-μ-T relationship is obtained. Seismic records of Classes C, D, and E sites are selected as excitations. Moreover, a nonlinear response time-history analysis is performed to establish the relationship between the η and T values for the equivalent ductility factor μ. Further, by exploring the effects of the site class, ductility factor, second-order stiffness coefficient, and period T on the mean value of η, a simplified calculation equation of mean η is derived, and η is used as a modified value for the traditional strength reduction factor R spectrum.

The purposes of this study were to (1) identify foreigners’ evaluation of service performance, (2) define foreigners’ needs for each segment of Korean traditional restaurants, and (3) plan the adaptation strategies for Korean traditional restaurants on foreign countries. From April to July, 2005, 542 foreigners responded to an individual survey. Statistical analyses on SPSS 12.0 for Windows were performed on the survey data using descriptive statistics, factor analysis, reliability analysis, independent-samples t-test and ANOVA. The major findings from the study are as follows. First, among all the attributes, ‘Offer free additional side dishes’ scored the highest, followed by ‘taste of food is good’ and ‘temperature of food is proper’. Second, factor analysis classified the service attributes into four factors in the following order of importance: menu, sanitation, service, and facility and atmosphere. Finally, foreigner groups categorized by their general characteristics, including demographics, showed statistically differences in their evaluation. In consequence, the research findings suggest that operators of Korean traditional restaurants should understand different customers’ needs within and between customer segments.

Purpose: With the introduction of Web 2.0, the advent of smartphones, and the recent outbreak of COVID-19 worldwide, interest in online shopping has soared. In an online shopping environment, the desire for impulse buying increases compared to offline shopping. Research design, data and methodology: In this study, three marketing stimulating factors such as product factor, price factor, and facilitating factor were selected which affect impulse buying for clothing and accessory products in the Korean online shopping environment. The mechanism of causal relationship among them, and the role customer value between marketing stimulating factor and impulse buying was analyzed. Results: The analysis results are as follows. First, the product factor had a significant positive effect on consumer value and impulse buying. Second, the price factor also had a significant positive effect on consumer value and impulse buying. Conclusions: Although the facilitating factor had no significant influence on consumer value and impulse buying, the indirect effect through consumer value was positively significant. Consumer value had a positive mediating effect on impulse purchase in the order of price factor, product factor, and promotion factor.

The importance of polysaccharides is increasing globally due to their role as a significant source of dietary prebiotics in the human diet. In the present study, in order to maximize the yield of crude polysaccharides from Pinus densiflora, response surface methodology (RSM) was used to optimize a two-stage extraction process consisting of steam explosion and water extraction. Three independent main variables, namely, the severity factor (Ro) for the steam explosion process, the water extraction temperature ($^{\circ}C$), and the ratio of water to raw material (v/w), were studied with respect to prebiotic sugar content. A Box-Behnken design was created on the basis of the results of these single-factor tests. The experimental data were fitted to a second-order polynomial equation for multiple regression analysis and examined using the appropriate statistical methods. The data showed that both the severity factor (Ro) and the ratio of water to material (v/w) had significant effects on the prebiotic sugar content. The optimal conditions for the two-stage process were as follows: a severity factor (Ro) of 3.86, a water extraction temperature of $89.66^{\circ}C$, and a ratio of water to material (v/w) of 39.20. Under these conditions, the prebiotic sugar content in the extract was 332.45 mg/g.

The purpose of this study is to explore the relative influence of psychological well-being and social support on the burnout of infant care teachers. Participants were 194 infant care teachers from 52 infant daycare centers in Gyeong-gi-do. Psychological burnout was assessed by the Maslach Burnout Inventory(Lee, 2011), psychological well-being was measured by the Psychological well-being scale(Cho & Cha, 2001) and social support was measured by the social support questionnaire(Bak, 1985). Date were analyzed using descriptive statistics and analysis, t-test, Pearson's correlation analysis, and multiple regression analysis. The major results of this study were as follows; First, there were differences in burnout in terms of marital status, work experiences, classroom operation type and income. Second, Infant care teachers' burnout was negatively correlated with psychological well-being and social support. Third, the most influential factor on infant care teachers' burnout was purpose in life, the second most influential factor was self-acceptance, the third most influential factor was emotional support, and the least influential factor was environmental mastery. Results of this study indicate that a psychological well-being enhancement program should be developed and emotional support from a social relationship network should be enhanced in order to prevent infant care teachers' burnout.

Moment Magnifier Method has been generally used in estimation of total column moment induced by geometric nonlinearity for reinforced concrete slender column design, however second order analysis such as P-${\Delta}$ method has been recommended by Code for better result. Member stiffness estimation is the most significant factor for accuracy of second order analysis. Equivalent Column stiffness based on theoretically obtained moment-curvature-thrust relationship has been proposed and the analytical results of the proposed method, MacGregor-Hage Method, Furlong's Method, and Moment Magnifier Method are compared with experimentally obtained data.

Thrust of linear motor is one of the important factor to specify motor performance. Maximum thrust can be obtained by increasing the current in conductor and is relative to the sizes of conductor and magnet. But, the current and the size of conductor have an effect on temperature of linear motor. Therefore, it is practically important to find design results that can effectively maximize the thrust of linear motor within limited range of temperature. Finite element analysis was applied to calculate thrust and the temperature of the conductor was calculated by the thermal resistance. The diameter of copper wire among design variables has discrete value and number of turns must be integer. Considering these facts, special techinque for optimum design is presented. To reduce excessive computation time of thrust in optimization, the design variables was redefined by analysis of variance and second order regression model for thrust was determined by response surface metheodology. As a result, it is shown that the proposed method has an advantage in optimum design of linear motor.

This study is to consider varying factors of internal/external informational and operational environments in libraries, and develop a new evaluation indicators for university libraries in digital environments. In order to do this research, the previous works have been investigated, and the Delphi study and our own analysis have been performed. The main research results are as follows. First, the results through the Delphi method that was to adopted to verify evaluation items and indicators determined by the literature review show that the repressed values for each evaluation category is greater than 3.00. overall average is 4.02. and standard deviation is ranged from 0.40 to 0.62 for each category. This means that the evaluation indicators are valid. Second, the factor analysis was performed to verify the construct validity of evaluation indicators. As a result. the cumulative variance of evaluation indicators consisting of 11 dimensions per factor is 72.733%. In turn, this result shows that the validity of these indicators is very reliable. Third, t-test and one way ANOVA are performed within significance probability 0.05 in order to verify differences in each librarians point of views for the degree of importance in evaluation indicators. The results show that these evaluation indicators are verified to be appropriate since there is no significant difference. Based on the Delphi study and our own analysis. we developed a new evaluation indicators that consists of 7 evaluation categories, 35 evaluation items, and 92 evaluation indicators.
