대면 서비스보다 비대면 서비스를 선호하는 소비자들의 증가로 인해 기업의 고객 응대의 형태도 변해가고 있다. 기존의 전화 상담보다는 인터넷에 글을 쓰는 형식으로 문의를 하는 고객이 증가하고 있으며, 관련 기업에서는 이와 같은 변화에 효율적으로 대처하기 위해, 텍스트 기반의 상담시스템에 대한 다양한 연구 및 투자를 하고 있다. 특히, 입력된 질의에 대해서 자동 답변하는 챗봇(ChatBot)이 주목받고 있으나, 낮은 답변 정확도로 인해 실제 응용에는 어려움을 겪고 있다. 이에 본 논문에서는 상담원이 중심이 되는 텍스트 기반의 상담시스템에서 상담원이 보다 쉽게 답변을 수행할 수 있도록 자동으로 답변을 추천해주는 자동답변추천 시스템을 제안한다. 실험에서는 기존 질의응답 시스템 구축에 주로 사용되는 문장유사도 알고리즘과 더불어 합성곱신경망을 이용한 자동답변추천 기법의 답변추천 성능을 비교한다. 실험 결과, 문장유사도 기반의 답변추천 기법보다 본 논문에서 제안한 합성곱신경망(Convolutional Neural Networks) 기반의 답변추천시스템이 더 뛰어난 답변추천 성능을 나타냄을 보였다.

Digital game is an entertainment content as well as a cultural content so that digital game can deliver social messages to make people confront with current problems. Based on Gonzalo Frasca's expanded model theory, this study aims to analyze independent games parodying reality on the level of the narrative and the gameplay to demonstrate that digital game can be a powerful medium to represent a satire on society. Parody games describe irrational side of society as being comical and provoke players' repetitive gameplay. Therefore, players can experience serious theme through casual play in the first-person, and realize the tragic reality directly.

This paper considers a panel regression model with ill-posed data and proposes the generalized maximum entropy(GME) estimator of the unknown parameters. These are natural extensions from the biometries, statistics and econometrics literature. The performance of this estimator is investigated by using of Monte Carlo experiments. The results indicate that the GME method performs the best in estimating the unknown parameters.

Innovation in technology has changed the form and meaning of performance work and its appreciation in its long history. Applied to performance art, the concept of digital media and ubiquitous also created new implications in aesthetics and technology. As a matter of fact, new elements of ubiquitous performance- new relationship between creators and the audience and the extension of the notion of 'audience'- are not newly introduced. These elements have been tried throughout hundreds years of performance history and is far more developed thanks to digital communication. In this study, we will discuss how these elements have been developed from the earlier text-based ubiquitous performance to 3D virtual world and contributed to the construction of the virtual culture.

It had been longer that the design mock-up was made mainly in order to test products. These days, it seems to be main stream that the working mockup is done because designers consider not only the design but also usability. In this study, the modular hardware toolkit, complimentary with Adobe Flash, was developed so that it solves the problem, the electronic hardware which the designers should struggle to make by themselves. This result thing could help the time of the design process to be short and contribute to make robust system rapidly.

The pile foundations have been chosen more frequently as the comprehensive development of the country progressed, especially where the ground conditions are not suitable for the construction and the dimension and the length of the piles utilized becomes larger and longer. The purpose of this study suggests the improvement method of construction management for PHC pile in an apartment house. To do This, We analyzed about current process and provided improved Process with IDEF method. And, The objectives of this research is to propose the means to solve the current problems and management factors from the results of the investigation.

In this study, a torsional test for U-type steel box girders was performed to observe the effects of the kind of panel for top lateral walateral bracings on the torsional behavior of the U-type steel girder system. For the structural tests, the test specimen with a two-thirds scale of the system actually constructed in the field was used. In the torsional test to observe the efects of top lateral bracings, the most economical arrangement of the top lateral bracing was found to be the panel width to length ratio of 1:1.5 with the inclined angle of $40^{\circ}$.

Application of wind turbine generator system (WTGS) needs researches for performance prediction, pitch control, and optimal operation method. Recently a new type WTGS is developed and under testing. The notable feature of this WTGS is that it consists of two rotor systems positioned horizontally at upwind and downwind locations, and a generator installed vertically inside the tower. In this paper, a nonlinear simulation software developed for the performance prediction of the Dual Rotor WTGS and testing of various control algorithm is introduced. This software is hybrid in the sense that FORTRAN is extensively used for the purpose of computation and Matlab/Simulink provides a user friendly GUI-like environment.

In these days, small devices like smartphones, TV, and projectors are popular, and they are being developed rapidly. The projector is being used in cinema and exhibition because it makes a big screen. This feature makes new expression named projection-mapping in art world. Projection-mapping is being utilized extensively in stages of performances, and it use variety of shape's screens. But projection-mapping has limitation in space. So in this paper, we propose new performance system for projection-mapping and it make possible to overcome many difficulties. Also, we discuss the result of using the system in actual performance. We hope to develop the utilization of projection-mapping in performance.
