표 질의응답이란, 주어진 표에서 질의문에 대한 답변을 자동으로 추출하거나 생성하는 기술을 말한다. 최근 언어모델을 사용한 연구들은 정답을 유도할 수 있는 명령문인 프롬프트를 활용하여 더 높은 성능을 보이고 있다. 본 연구에서는 표 질의응답의 성능을 향상시키기 위해, 프롬프트를 효과적으로 사용할 수 있는 모델을 제안한다. 이와 함께, 다양한 형태의 프롬프트를 사용하여 모델을 평가한다. 실험 결과, 기본 모델에 단순 질의문만 입력으로 사용했을 때의 성능 F1 67.5%에 비해, 다양한 프롬프트를 입력으로 사용한 경우 1.6%p 향상된 F1 69.1%을 보였다. 또한, 다양한 프롬프트와 함께 제안 모델을 사용했을 때에는 기본 모델보다 2.2%p 높은 F1 69.7%을 달성했다.

This study aims to suggest the detailed evaluation criteria based on performances for rock slopes. Using the previous research result, final evaluation items are proposed considering characteristics and similarities of each evaluation item. Weight for each evaluation item is deducted using AHP method, verification for suggested evaluation criteria is conducted based on correlation analysis. The research results as follows. All evaluation items have a high statistical correlation with final evaluation result(safety rating). Especially, items of the "rockfall", "ground deformation", "discontinuity characteristic", "instable lithology" were shown the highest in relative correlation coefficient(R), It is judged that items and weight presented in this study well reflect characteristics of rock slopes.

This study proposes a new rapid-screening method for more reasonably evaluation the seismic capacities of low-rise RC buildings controlled by both shear and flexure. At the same time, this develops the equation of damage judgement and seismic capacity evaluation for quantitatively evaluating the seismic capacities. Using this evaluating method, it is impossible to estimate the evaluation score and earthquake-damage degree confronted with this and evaluate for efficiently the seismic capacities

In a performance-based evaluation of structures in use, the current performance is assessed by summing up the weighting of the evaluation indices for each performance. In this study, to suggest a performance-based evaluation technique for NATM tunnels in use, the performance evaluation indices were derived by examining the characteristics and similarities of each index developed from previous study. The weighting of the evaluation indices was derived by calculating the relative importance of each evaluation indices from the AHP analysis. In order to develop a quantitative evaluation model, grading criteria for each performance index was derived through literature review, and performance evaluation tables for road and railway tunnels were presented. In order to verify the significance of the proposed performance evaluation model, the correlation analysis was performed between each evaluation index and the final evaluation result. In the correlation analysis, the survey data measured through precision safety diagnosis in the tunnel in use was applied. It may be said that the proposed evaluation indices, weighting, criteria and evaluation models for tunnels in use can be applied to the performance-based maintenance system of tunnels.

The present study proposes a phased model to assess the lifecycle $CO_2$ amount of concrete structures. The considered system boundary is from cradle to recycling, which includes constituent material, transportation, batching and mixing in ready-mixed concrete plant, use and demolition of structure, and crushing and recycling of demolished concrete. The $CO_2$ uptake of concrete by carbonation during lifetime (40 years) of a structure and the recycling life (20 years) after demolition is estimated using a simple approach generalized to predict the carbonation depth from the surfaces of concrete element and recycled aggregates. Based on the proposed phased model, a performance evaluation table is realized to straightforwardly examine the lifecycle $CO_2$ amount of concrete structures. The proposed model demonstrates that the contribution of ordinary portland cement (OPC) to lifecycle $CO_2$ emission of the concrete structure occupies approximately 85%. Furthermore, the $CO_2$ uptake is estimated to be approximately 15~18% of the lifecycle $CO_2$ emissions of concrete structures, which corresponds to be 19~22% of the emissions from OPC production. Overall, the proposed $CO_2$ performance table is expected to be practically useful as a guideline to determine the $CO_2$ emission or uptake at each phase of concrete structures.

This paper presents a methodology for evaluating suitability of a manned-unmanned aerial vehicle team for a complicated mission. The study identified vehicle performance, equipment performance and level of autonomy as the key factors that affect the mission effectiveness. A manned and an unmanned aircraft were compared, and their performance was quantized in these respects. SEAD was chosen as a representative manned-unmanned team mission. The SEAD mission was broken down to a sequence of tasks. Mission experts evaluated the importance of each mark item for the mission legs. Combining the results showed proper type of aircraft for each leg depending on the complexity, safety, and importance of the task. Finally, the whole mission plan was laid out as a time-based sequence which alleviate pilot workload significantly.
