  • 외상후 뇌손상은 대표적이며, 가장 중요한 신경정신계 질환의 하나이다. 더욱이 외상후 뇌손상 환자들은 각종의 사고 및 산업재해 등으로 인해 그 수가 급증하고 있으며, 특히 인지기능의 장애로 인한 다양한 기질성 정신장애로 고통을 겪게 된다. 따라서 외상후 뇌손상은 손상의 시점에서부터 정확하고 올바른 평가는 물론 손상후의 경과 및 치료대책의 수립에 있어서 체계적이며 종합적인 신경인지기능의 평가는 필수적이다. 왜냐하면 신경인지기능평가는 뇌의 손상부위와 이와 관련된 기능장애 및 행동의 변화에 대한 객관적인 자료를 제시해 주기 때문이다. 신경인지기능 평가의 영역은 지각, 운동기능은 물론 주요인지기능인 기억, 언어, 실행 및 감정조절능력에 이르기까지 다양하며, 외상후 뇌손상환자들은 손상부위 및 정도에 따라 신경인지기능의 장애를 초래하게 된다. 대표적인 신경인지기능평가 도구로는 KWIS, Halstead-Reitan, Luria-Nebraska batteries, 특히 전두엽기능검사인 Wisconsin Card Sorting Test (WCST)를 비롯하여, 현재는 PC/S Vienna Test System 및 Stim등의 각종 전산화 인지기능검사가 개발되어 임상에서 활발히 사용되고 있다. 즉 외상후 뇌손상환자를 위한 신경인지기능평가의 목적은 뇌손상과 관련된 신경인지기능장애를 정확히 평가하여, 환자 개개인에 적합한 인지재활치료 계획을 수립하는데 있다. 물론 여기에는 신경정신상태검사(neuropsychiatric mental status examination)를 통하여 외상 후 뇌손상의 경과 및 예후에 결정적인 영향을 미칠 수 있는 나이, 의식소실 및 외상후 기억 손상 시간의 정확한 측정은 물론 심리 사회 문화적인 상태와 두부외상전 환자의 지적수준 및 사회 적용기능이 함께 평가되어야 할 것이다.

  • The visual system applies previously learned contextual knowledge to facilitate the perception and encoding of scenes. When extrapolation following the employment of contextual information occurs, it sometimes leads to scene memory distortion: people report as if they saw more than they actually had seen. This phenomenon is called the "boundary extension" effect (Intraub & Richardson, 1989). The present study aimed to clarify the effects of contextual information on boundary extension in a more systematic way. Based on the assumption that it is harder to extract contextual information from inverted scenes compared to intact scenes, we presented inverted scenes either during encoding or retrieval to manipulate the level of contextual information and compared the magnitude of boundary extension effect for upright versus inverted scenes. In a series of experiments, we found that scene inversion during encoding, but not during retrieval, significantly reduced boundary extension. Showing reduced memory distortion for inverted scenes, the current study directly demonstrated that access to contextual information is a critical component of scene extrapolation process.

  • I studied in this paper on the comparative study between the constructivism and the structuralism as the educational methods. On the constructivism in educational methods they say that knowledge is constructed subjectively by person individually(cognitive constructivism) or by persons reciprocally in the society(social constructivism). On the structuralism in educational methods they say that knowledge(structure) is in the closed-end text objectively and person pursue and identify this objective knowledge in the closed-end text. But on the post-structuralism(neostructuralism) they say that the text is not closed-ended but open-ended. So constructivism is consistent with post-structuralism. Education include application of knowledge and awareness of knowledge on my opinion. Education on application of knowledge is more important in this knowledge based society. Constructivism connote the application of knowledge in the education. School library media center and media specialist(teather-librarian) are essential elements of this application of knowledge in the education.

  • The research area for solving question answering (QA) problems using artificial intelligence models is in a methodological transition period, and one such architecture, the dynamic memory network (DMN), is drawing attention for two key attributes: its attention mechanism defined by neural network operations and its modular architecture imitating cognition processes during QA of human. In this paper, we increased accuracy of the inferred answers, by adapting an automatic data augmentation method for lacking amount of training data, and by improving the ability of time perception. The experimental results showed that in the 1K-bAbI tasks, the modified DMN achieves 89.21% accuracy and passes twelve tasks which is 13.58% higher with passing four more tasks, as compared with one implementation of DMN. Additionally, DMN's word embedding vectors form strong clusters after training. Moreover, the number of episodic passes and that of supporting facts shows direct correlation, which affects the performance significantly.

  • In this paper a systematic numerical analysis is performed to obtain the hysteresis behavior of partially restrained top and seat angle connections subjected to cyclic loading. This connection includes superelastic shape memory alloy (SMA) angles and rods in order to secure the recentering capacities as well as proper energy dissipation effects of a CFT composite frame. The three-dimensional nonlinear finite element models are constructed to investigate the rotational stiffness, bending moment capacity and failure modes. A wide scope of additional structural behaviors explain the different influences of the connection's parameters, such as the various thickness of connection angles and the gage distance of steel and SMA rods.

  • Recent research shows that emotion is closely related to memory and learning. Although a growing number of educators have high interest in affective aspects of learning processes and outcomes, there are few studies to investigate systematically instructional strategies and learning environments based on learners' emotion. Despite the efforts to understand the role of emotion and to facilitate positive emotion for meaningful learning in face-to-face and online environments, it is still a challenging issue to measure emotion in a valid and reliable way. To implement emotion-based education, it is essential to overcome the limitation of self-report surveys on emotion, which rely on the memory of learners. The current study surveyed emotion measurement tools, which are recently developed in education and other domains, in terms of self-report, neurophysiology, and behavioral responses. This study also discussed how emotion measurement tools can be used in authentic learning and teaching situations. Particularly, this study focused on cutting-edge technologies that would enable educators to collect and analyze learners' emotion easily in real-world contexts. This study will contribute to the research about the role of emotion in education and the design of adaptive learning environments that consider the change of learners' emotion.

  • The partially restrained smart CFT (concrete filled tube) column-to-beam connections with top-seat split T connections show various behavior characteristics according to the changes in the diameter and tightening force of the fastener, the geometric shape of T-stub, and material properties. This paper presents results from a systematic three-dimensional nonlinear finite element study on the structural behavior of the top-seat split T connections subjected to cyclic loadings. This connection includes super-elastic shape memory alloy (SMA) T-stub and rods to obtain the re-centering capabilities as well as great energy dissipation properties of the CFT composite frame. A wide scope of additional structural behaviors explain the influences of the top-seat split T connections parameters, such as the different thickness and gage distances of split T-stub.

  • Along with and <1Q84> Murakami Haruki sees through human nature that fades away with time in his latest work with 'color and memory'. This is the type of character or story to read with the deployment of instrument. Costume of characters conceived in the expansion of the body, the inner expression of personal notes. To others what you want to look, how they formed on the body, with a range of social, if you are claiming a statement. To form the body by forming self-practice is that there becomes. This paper the inside of the characters and the apparent strong interest in the set, costume characters, especially characters were recognized as representing the device of novel. Work directly in the results, or is described as a symbolic system of the body and clothing that embodies the meaning of the symbol you want to the structure of the exchange.

  • This study aimed to reveal that a local city was recreated by tourism, and to discover a general process in which the regional identity as a tourist destination was reconstructed. Specifically, firstly, this study suggested that the social construction of cultural tourist destinations was composed of a series of dynamic stages such as 'reinterpretation', 'institutionalization', and 'recognition' conceptually. Secondly, the dynamic stages were analyzed on the ethnographic study of Otaru where the movement of preservation of the historical canal was raised and strategies to attract tourism had been implemented. Thirdly, a main mechanism acting on each stage was examined. In conclusion, it was shown that the region was reinterpreted through the politics of identity and the meaning was institutionalized through political and economic negotiation. Moreover, while being established as a constructed authenticity by politics of memory, the regional identity was embedded in the socio-spatial consciousness constantly.

  • The traditional network anomaly detection systems execute the threshold-based detection without considering dynamic network environments, which causes false positive and limits an effective resource utilization. To overcome the drawbacks, we present the adaptive network anomaly detection model based on artificial immune system (AIS) in centralized network. AIS is inspired from human immune system that has learning, adaptation and memory. In our proposed model, the interaction between dendritic cell and T-cell of human immune system is adopted. We design the main components, such as central node and router node, and define functions of them. The central node analyzes the anomaly information received from the related router nodes, decides response policy and sends the policy to corresponding nodes. The router node consists of detector module and responder module. The detector module perceives the anomaly depending on learning data and the responder module settles the anomaly according to the policy received from central node. Finally we evaluate the possibility of the proposed detection model through simulation.
