본 연구는 아동들의 창의력 증진과 인성 함양을 위하여 러시아에서 개발된 '교훈적 동화 만들기' 수업 모형을 탐색하고 우리나라에서의 적용 방안을 제시하고자 한다. 동화는 아동들이 자신의 창의력을 펼쳐 보이고 자신의 잠재적 능력을 확인해 볼 수 있는 첫 관문 중 하나이며, 자신을 인식하고 성취감을 통한 자신의 감정을 체험할 수 있는 좋은 장르이다. 이 수업을 통해 아동들은 문학 작품의 장르를 인식하고 구별할 수 있으며, 동화를 만들기 위한 알고리듬을 익히고, 이러한 알고리듬을 바탕으로 해서 교훈적인 동화를 만들어 본다. 작품을 만들기 위해 상상하고, 분석하고, 만들어가는 과정 속에서 아동들의 상상력과 창의력 및 언어적 표현력이 더욱 개발될 것이며, 동시에 일상생활에서 삶의 도덕적이고 윤리적인 요소들을 좀 더 면밀하게 살피고 활용하며, 내면화하는 작업을 익히게 될 것이다.

본 연구는 내진설계 되지 않은 학교시설물 중 다수를 차지하는 1980년도 표준설계 도면(건설부 공고 제130호, 1980년 10월 28일)에 의하여 건설된 국내에 현존하는 4층 모멘트 연성골조의 학교건물을 대상으로 이력모델의 특성과 지진파의 특성에 따라 표준학교건물의 비탄성지진거동을 분석하고자 한다. El-centro지진은 주파수 성분과 강진지속시간의 특성에 의하여 표준학교건물의 단변방향 층전단력, 층간변위비, 층변위 응답에 매우 큰 영향을 미치며 특히 수정다케다모델 선택시 응답의 차이가 매우 크게 나타남을 알 수 있다. 층전단력의 경우 최대 46%, 층간변위비의 경우 최대 70%, 층변위의 경우 최대 59%의 편차를 보인다. Santa Monica지진은 장변방향의 응답에서 이력모델별 편차가 더 크게 나타났으며, 층전단력은 최대 59%, 층간변위비는 최대 65%, 층변위는 최대 50%의 편차를 보였다. 이는 장변방향의 고유주기가 단변방향에 비하여 크기 때문에 1초이상의 주기성분이 많은 Santa Monica지진의 특성에 의한 것으로 판단된다. Taft지진은 이력모델에 따른 층간변위비와 층변위 응답의 편차가 가장 적은 것으로 나타났으며, 층간변위비는 최대 15%, 층변위는 최대 5%의 편차를 보여 변위응답에 있어서 이력모델에 가장 의존도가 적은 결과를 얻을 수 있을 것으로 판단 된다.

Research using artificial intelligence to generate captions for an image has been studied extensively. However, these systems are unable to create creative stories that include more than one sentence based on image content. A story is a better way that humans use to foster social cooperation and develop social norms. This paper proposes a framework that can generate a relatively short story to describe based on the context of an image. The main contributions of this paper are (1) An unsupervised framework which uses recurrent neural network structure and encoder-decoder model to construct a short story for an image. (2) A huge English novel dataset, including horror and romantic themes that are manually collected and validated. By investigating the short stories, the proposed model proves that it can generate more creative contents compared to existing intelligent systems which can produce only one concise sentence. Therefore, the framework demonstrated in this work will trigger the research of a more robust AI story writer and encourages the application of the proposed model in helping story writer find a new idea.

In this study, the seismic response is investigated by using a relatively low-rise building under torsion-prone conditions and three seismic loads with change of the location of the seismic isolation system. LRB (Lead Rubber Bearing) was used for the seismic isolator applied to the analytical model. Fixed model without seismic isolation system was set as a basic model and LB models using seismic isolation system were compared. The maximum story drift ratio and the maximum torsional angle were evaluated by using the position of the seismic layer as a variable. It was confirmed that the isolation device is effective for torsional control of planar irregular structures. Also, it was shown that the applicability of the mid-story seismic isolation system. Numerical analyses results presented that an isolator installed in the lower layer provided good control performance for the maximum story drift ratio and the maximum torsional angle simultaneously.

This study aimed to develop a seismic retrofit technique using a steel frame which can be easily transported and assembled on site. This enables the retrofit steel frame to be easily attached to an existing structure minimizing the unwanted gap between the structure and the steel frame assembly. A one-story one-bay RC frame was tested with and without seismic retrofit using the proposed steel frame to verify the seismic retrofit effect of the proposed system, and an analysis model was developed in Opensees for seismic performance evaluation of a case study soft first-story model structure retrofitted with the developed steel frame assembly. Seismic performance of the model structure was also evaluated considering soil structure interaction effect. The experimental study confirmed that the proposed seismic retrofit system can be applied effectively to improve the seismic performance of framed structures. Time history analysis results of the model structure showed that the proposed steel frame assembly was effective in increasing the seismic load resisting capacity of the soft first-story structure. However more steel frame assemblies were required to satisfy the given performance limit state of the model structure located on weak soil due to the negative soil-structure interaction effect.

Retrofit of soft-story buildings due to seismic loads using Gap-Inclined-Brace (GIB) system is considered a new retrofit technique that aims to maintain both strength and stiffness of structure. In addition, it provides more ductility and less P-delta effect, and subsequently better performance is observed. In this paper, the effect of the eccentricity between GIB and the retrofitted column due to installation on the efficiency of the retrofitting system is studied. In addition, a modification in the determination method of GIB properties is introduced to reduce the eccentricity effect. Also, the effect of GIB system on the seismic response of mid-rise buildings with different heights considering soft-story at various heights has been studied. A numerical model is developed to study the impact of such system on the response of retrofitted soft-story buildings under the action of seismic loads. To achieve that goal, this model is used to perform a numerical investigation, by considering five case study scenarios represent several locations of soft-story of two mid-rise reinforced concrete buildings. At first, Non-linear static pushover analysis was carried out to develop the capacity curves for case studies. Then, Non-linear time history analyses using ten earthquake records with five peak ground accelerations is performed for each case study scenario before and after retrofitting with GIB. The results show that large GIB eccentricity reduce the ultimate lateral resistance and deformation capacity of the retrofitting system. Moreover, the higher the retrofitted building, the more deformation capacity is observed but without significant increase in ultimate lateral resistance.

When the center of stiffness and the center of mass of the structure differ under the seismic load, torsion is caused by eccentricity. In this study, an analysis model was modeled in which the positions of the core and the plane rotation axis of a 60-story torsional atypical structure with a plane rotation angle of 1 degree per floor were different. The structural behavior of the analysis model was analyzed, and the earthquake response behavior of the structure was analyzed based on the time history analysis results. As a result, as the eccentricity of the structure increased, the eccentricity response was amplified in the high-rise part, and the bending and torsional behavior responses were complex in the low-order vibration mode. As a result of the analysis, the maximum displacement and story drift ratio increased due to the torsional behavior. The maximum story shear force and the story absolute maximum acceleration showed similarities for each analysis model according to the shape of the vibration mode of the analysis model.

A sophisticated story-wise stiffness identification method for a shear building structure is applied to the case where the shear building is subjected to an actual micro-tremor. While the building responses to earthquake ground motions are necessary in the previous method, it is shown that micro-tremors can be used for identification within the same framework. This enhances the extended usability and practicality of the previously proposed identification method. The difficulty arising in the limit manipulation at zero frequency in the previous method is overcome by introducing an ARX model. The weakness of small SN ratios in the low frequency range is avoided by using the ARX model together with filtering and introducing new constraints on the ARX parameters.

The nonlinear analysis was perforned for a 2-bay 2-story moment-resisting reinforced concrete plane frame with seismic detail using KDARC 2D program. The analytical models consist of the material model, the member model, the hysteretic model, and the damage model etc. The conclusion based on the results of analysis is as following. : (1) Story shear-displacement relationship is similar to the experiment result but from the energy point of view, the analysis relationship is similar to the experiment result but from the energy point of view, the analysis result was different from the experiment result. (2) Plastic hinges were found to occur mainly in beams at first story while all the columns had plastic hinges throughout the structure. (3) Failure mode is a little different from experiment result in the yielding mechanism. (4) Damage index isabout 0.25. This means that the degree of damage is moderate and can be repairable.
