특허수명은 특허가치를 평가하는 척도로 사용되어 왔다. 본 연구에서는 특허수명을 예측하여 개별특허의 가치를 평가함에 있어, 특허의 내적가치요소와 외적가치요소를 하나의 모델로 평가하기 위하여 화학반응속도 추정식으로 널리 알려진 아레니우스식을 사용한 새로운 평가모델을 제시하였다. 한국의 소멸된 특허데이터를 활용하여 평가모델의 성능을 검증하였으며, 선행연구에서 특허평가모델로 사용되었던 SVM, Logistic reg., ANN 모델과 성능을 비교하였다. 결과적으로, 제안한 평가모델이 다른 모델 보다 정확도가 높았으며, 특허권자의 특성을 고려한 상대체감비용지수 반영 시 여러 평가모델에서 정확도가 상승하는 경향을 보였다. 또한, 특허의 예측수명등급과 특허의 실제수명과는 강한 상관관계가 있었다. 이러한 평가모델은 대량의 특허를 객관적으로 신속하게 평가할 수 있으며 특허의 유지여부에 대한 의사결정 혹은 기술거래나 평가에 활용할 수 있다. 특히, 평가목적에 따라 특허만을 평가하거나 사업화주체나 기술적 특성을 고려한 평가가 필요한 경우에 각각 사용될 수 있다.

Purpose - The purpose of this study is to evaluate the economic effects of FTAs using the concept of value-added exports. So far, the economic effects of FTAs have been dependent on decrease in import prices due to tariff cuts in importing countries, but the actual tariff reduction need to consider the value added of the exporting countries. Design/methodology - Value-added export refers to the added value created in the exporting country out of total exports. Among value-added exports, direct value-added export is interpreted as the Regional Value Contents (RVC), from which the economic effect of the FTA can be analyzed. A modified GTAP-VA model takes into account RVC in order to estimate accurate effects of FTAs. Findings - By the re-evaluation of the FTA based on the RVC, this paper makes it clear that the economic effects of the existing FTA methodology have the possibility of overestimation. In addition, as a new FTA with a strengthened Rules of Origin (ROO) is being initiated, a negative impact on international trade and GVC utilization may occur. Originality/value - This study introduces the concept of value-added export in analyzing the effects of FTAs. The new analysis methodology of this paper emphasizes the importance of value-added exports. Re-organization of GVCs would change regional trade agreements and empower ROO by weakening existing GVCs and transforming the value chain from global into regional scope.

The purpose of this study was to determine the optimization mixing ratio of wheat sprout powder (WSP) and hemicellulase for the preparation of white pan bread. Using a response surface methodology, independent variables were WSP and hemicellulase. Dependent variables were physicochemical properties, antioxidant properties and sensory evaluation. Water binding capacity of dough increased with increasing WSP. Color value showed positive correlations with WSP. L value decreased and a, b values increased as WSP increased. The adjusted determination coefficient of texture analysis was calculated to be 0.7230~0.9446 having the p-value less than 0.1. Specific volume of bread showed a positive correlation with hemicellulase and a negative correlation with WSP. DPPH radical scavenging activity and total polyphenol were represented by a linear model and showed positive correlations with WSP. Sensory evaluation were represented by a quadratic model. In conclusion, the optimal formulation for WSP added bread, as assessed by numerical and graphical optimization methods, was WSP 2.36%, hemicellulase 0.069% per wheat flour 100 g. The above results indicate that WSP can be used as health-oriented material in the bread industry. This is also expected to meet demands of consumers who are in the pursuit of healthy food.

The dichotomous-choice contingent valuation method is applied to estimate the landscape value of Jeju mandarin(orchard). A distribution-free approach, Turnbull empirical distribution model, is employed to solve negative willingness to pay and truncation problems. The data used are collected from the interviews with tourist about willingness-to-pay at the various donation amount levels of Jeju mandarin(orchard)'s landscape value. The evaluation result is shown that the average amount of willingness to pay for the Jeju mandarin's landscape value is 12,926 won per person with standard deviation of 1,874.7 won/person. When the number of Jeju visitors is considered, the economic value of Jeju mandarin's landscape rises every year(2005:64.89 billion won, 2011: 84.43 billion won). The average economic value of Jeju mandarin's landscape are estimated 59.65 billion won during 2000-2005 and 76.88 billion won during 2006-2011, respectively.

The outlines of seismic PSA implementation standards and seismic hazard evaluation procedure were shown. An overview of the cause investigation of seismic motion amplification on the Niigata-ken Chuetsu-oki (NCO) earthquake was also shown. Then, the contents for improving the seismic hazard evaluation methodology based on the lessons learned from the NCO earthquake were described. (1) It is very important to recognize the effectiveness of a fault model on the detail seismic hazard evaluation for the near seismic source through the cause investigation of the NCO earthquake. (2) In order to perform and proceed with a seismic hazard evaluation, the Japan Nuclear Energy Safety Organization has proposed the framework of the open deliberation rule regarding the treatment of uncertainty which was made so as to be able to utilize a logic tree. (3) The b-value evaluation on the "Stress concentrating zone," which is a high seismic activity around the NCO hypocenter area, should be modified based on the Gutenberg-Richter equation.

The in-situ pushover test differs from the shake-table test because it is performed outdoors and thus its size is not restricted by space, which allows us to test a full-size building. However, to build a new full-size building for the test is not economical, consequently scholars around the world usually make scale structures or full-scale component units to be tested in the laboratory. However, if in-situ pushover tests can be performed on full-size structures, then the seismic behaviors of buildings during earthquakes can be grasped. In view of this, this study conducts two in-situ pushover tests of reinforced concrete (RC) buildings. One is a masonry-infilled RC building with openings (the openings ratio of masonry infill wall is between 24% and 51%) and the other is an RC building without masonry infill. These two in-situ pushover tests adopt obsolescent RC buildings, which will be demolished, to conduct experiment and successfully obtain seismic capacity curves of the buildings. The test results are available for the development or verification of a seismic evaluation model. This paper uses ASCE 41-17 as the main evaluation model and is accompanied by a simplified pushover analysis, which can predict the seismic capacity curves of low-rise buildings in Taiwan. The predicted maximum base shear values for masonry-infilled RC buildings with openings and for RC buildings without masonry infill are, respectively, 69.69% and 87.33% of the test values. The predicted initial stiffness values are 41.04% and 100.49% of the test values, respectively. It can be seen that the ASCE 41-17 evaluation model is reasonable for the RC building without masonry infill walls. In contrast, the analysis result for the masonry infilled RC building with openings is more conservative than the test value because the ASCE 41-17 evaluation model is limited to masonry infill walls with an openings ratio not exceeding 40%. This study suggests using ASCE 41-17's unreinforced masonry wall evaluation model to simulate a masonry infill wall with an openings ratio greater than 40%. After correction, the predicted maximum base shear values of the masonry infilled RC building with openings is 82.60% of the test values and the predicted initial stiffness value is 67.13% of the test value. Therefore, the proposed method in this study can predict the seismic behavior of a masonry infilled RC frame with large openings.

This study investigated if and why there are gulfs between expectations and perceived value for usability. The main objectives of this study are as follows: (a) to examine the differences between expectation and perceived value for usability toward an OTA; and (b) to investigate the reason and purpose for customer visits toward an OTAs. By analyzing the distance between expected and the perceived value for the usability, OTAs can then close this distance and then be able to improve the usefulness of their websites. In addition, after investigating previous evaluation problems, that the various factors that are associated with tourism website evaluations, may be downsized to fit a comprehensive model for website evaluations. The results help to close the gap between expectation and perceived value by helping with the websites design, development, implementation, and management of systems. Based on those findings, effective strategies for OTAs marketing and promotional strategies are suggested.
