The purpose of this study was to understand the influence of corporate association in family restaurants upon the customer's service valuation and company evaluation and to empirically analyze whether the service valuation plays a mediating role between the corporate association and the company evaluation. Self-administered questionnaires were completed by 301 customers and the data were analysed by frequency, factor analysis, reliability analysis, correlation analysis and multiple regression analysis. The primary results are as follows. Multiple regression analysis, to verify the hypothesis, showed that corporate association(corporate competence association $\beta$=0.636; corporate social responsibility association $\beta$=0.091) in family restaurants had positively significant influence upon service valuation, and service valuation($\beta$=0.567) had positively significant influence on company evaluation. As a result of analyzing the mediating effects, the direct effects(corporate competence association $\beta$=0.166; corporate social responsibility association $\beta$=0.123) of the corporate association in family restaurants upon customer's corporate evaluation were indicated to be smaller than the total effects(corporate competence association $\beta$=0.430; corporate social responsibility association $\beta$=0.161). Accordingly, the partial mediating effect was surveyed to exist that has influence upon company evaluation through service evaluation without explaining 100% directly in evaluation on corporate association.

Today, a desirable way to manage livestock manure is to activate its utilization as a resource. The production of high quality liquid fertilizer of livestock manure is very important because it increases the use of various liquid fertilizer. However, the result of mature evaluation with a maturity measuring instrument for liquid fertilizer showed that the deviation of concentration between liquid fertilizer did not bring into uniformity. The result is also making sure that quality management for liquid fertilizer is not smoothly made. Quality evaluation for compost and liquid fertilizer includes physical, biological, chemical and microbiological methods, but a chemical method is mainly being implemented due to fairness and field application. Therefore, this study figured out correlation in feces and urine through regression analysis of livestock manure and tried to create a research plan to carry out efficient quality analysis of managing livestock manure.

This paper assesses the suitability of existing standards for plastic material models and performance level evaluation methods in seismic performance evaluations of concrete dam piers during Maximum Credible Earthquakes (MCE). Dynamic plastic analysis was conducted to examine the applicability of the plastic material model under various conditions. As a result reveal that when the minimum reinforcement ratio is not met, the average stress-average strain method recommended in current dam seismic performance evaluation guidelines tends to underestimate pier responses compared to the predicted outcomes of dynamic elastic analysis. Consequently, the paper proposes an improvement plan that treats dam piers with an insufficient minimum reinforcement ratio as unreinforced and integrates fracture energy into concrete tensile behavior characteristics for performance level evaluation. Implementing these improvements can lead to more conservative evaluation outcomes compared to current seismic performance evaluation methods.

The purposes of this study are to evaluate the power performance through CFD analysis and structural integrity through uni-directional FSI analysis in aerodynamic design and structure design of wind turbine blade. The blade was designed to generate the power of 2MW under the rated wind speed of 11 m/s, consisting of NACA 6 series, DU series and FFA series airfoil. The inside section of the blade was designed into D-spar structure and circular stiffener was placed to reinforce the structural strength in the part of hub. CFD analysis with the application of transitional turbulence model was performed to evaluate the power performance of blade according to the change of TSR and 2.024MW resulted under the condition of rated wind speed. TSR of 9 produced the maximum power coefficient and in this case, Cp was 0.494. This study applied uni-directional FSI analysis for more precise evaluation of structural integrity of blade, and the results of fiber failure, inter fiber failure and eigenvalue buckling analysis were evaluated, respectively. For the evaluation, Puck's failure criteria was applied and the result showed that fiber failure and inter fiber failure did not occur under every possible condition of the analysis. As a result, power performance and structural integrity of 2 MW blade designed in this study turned out to satisfy the initial design goals.

The purpose of this paper was to analyze the role of illustrations in elementary textbooks (3~4 grade) of the 2009 revised curriculum of science education in Korea from point of view of aim of science by applying the criteria of 5E inquiry process model for reflecting core aim of the science education. The subjects of the paper was the 105 illustrations in the earth-science domain of elementary science textbooks (3~4 grade) of the 2009 revised curriculum of science education in Korea. The analysis criterion was of two categories, the function of illustration and the role of illustration. the function of illustration was divided into three subcategories such as Exclusiveness type, correspondence type and supplementary type. The role of illustration was divide into five subcategories such as Engagement, Exploration, Explanation, Elaboration and Evaluation. According to results of the illustration analysis are as follows: the result of the function of illustration are exclusiveness type 39, correspondence type 36 and supplementary type 30, the important of point to note is that there are a lot of exclusiveness type considerably. compared with other subjects, this fact indicate character of illustration of the only science textbook. The result of the role of illustration are Engagement 14, exploration 64, explanation 25, elaboration 2 and evaluation 0. This data indicate main role of illustrations in earth-science domain is to help the students to be able to observe and explore. Cross-analysis of the function and role was a significant difference. Role of illustration was evenly distributed within Exclusiveness type on the other hand, the role of illustrations was mainly exploration and explanation in correspondence and supplementary type. Especially, illustration of exploration was mainly correspondence type.
