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.

The purpose of this study is to review foreign scenic inventory map for the systematic management of natural scenic resources. Several foreign cases were surveyed and analyzed to apply the scenery inventory map in domestic, such as Visual Resource Management(VRM) from United States Bureau of Land Management, Scenery Management System(SMS) from USDA Forest Service and Visual Landscape Inventory(VLI) from British Columbia Ministry of Forest's, that were already established scenery inventory maps. The results are as follows. First, the characteristic of Korean landscape is quite a different from those of north american's, which is much smaller and more complex in topography and land use. So, it would be difficult to apply foreign system directly and we need more researches to our own system. The multi-stepped landscape unit system is highly recommended. Second, scenic quality could be estimated by the pre-built database, such as land forms, vegetation, hydrology and land uses. Historical and cultural attributes should be complemented. Third, existing scenic integrity could be grasped by scenic damage, landscape alteration caused by human activities and land exfoliation. Also, subjective evaluation method should be supplemented by objective criteria through further detailed studies. Finally, about landscape view conditions, landscape control points should be surveyed and established in advance, and viewing distance, viewing frequency, amount of observers and public interests should be considered.

Current global textiles and fashion industries have gradually shifted focus to high value-added, high sensibility, and multi-functional products based on new human-friendliness and sustainable growth technologies. Textile design CAD systems have been developed in conjunction with computer hardware and software sector advances. This study compares the patterns or images of actual woven fabrics and virtual fabrics prepared with a textile design CAD system. In this study, several weave structures (such as fancy yarn weave and patterns) were prepared with a shuttle loom. The woven textile images were taken using a CCD camera. The same weave structure data and yarn data were fed into a textile design CAD system in order to simulate fabric images as similarly as possible. Similarity Index analysis methods allowed for an analysis of the index between the actual fabric specimen and the simulated image of the corresponding fabric. The results showed that repeated small pattern weaves provide superior similarity index values than those of a fancy yarn weave that indicate some irregularities due to fancy yarn attributes. A Complex Wavelet Structural Similarity(CW-SSIM) index resulted in a better index than other methods such as Multi-Scale(MS) SSIM, and Feature Similarity(FS) SSIM, across fabric specimen images. A correlation analysis of the similarity index based on an image analysis and a similarity evaluation by panel members was also implemented.

Every individual uses, appraises and interacts with products on a daily basis. It is evident from current trends and theories associated with product design, that these products that are a part of our everyday lives, satisfy our needs in two ways, functionally and psychologically. While a product's usability or the service it provides may satisfy our functional needs, it is often the case that when given a choice, we may select one product from the other, even though they are functionally alike. Why do we make these choices, and more importantly, how? When users are satisfied with a product's performance, they seek a stronger emotional involvement with them(Lewalski, 1988). Are emotions responsible for our choices, likes and dislikes of products? What is the nature of this emotional involvement, what are these emotions, and how, if possible, can we design to generate specific emotions? This research proposes to develop into these questions. It is an effort to formulate the underpinnings of "design for emotions" and uncover the possibilities of a design process that places "emotion" as an equally important concern for the design of objects, as functionality or aesthetic appeal. The literature review will include a systematic study of human and product attributes, theoretical and empirical studies of emotion, and the interaction of humans and products is discussed. This project examines what product characteristics lead to an emotional experience, when people interact with them, and suggests a methodology or design guidelines that may allow designers to enhance or specifically modify the emotions experienced by people, while using the products that are a part of their everyday lives.

Chemicals for cosmetics, including skin, the skin absorbs some of the research in the field of science or pharmacy recently, about the environment and the health of the heightened interest in skin absorption. Many other human attributes and absorption evaluation studies are underway in various areas. This study were used rats and carried out to find out the effects of commercial permanent wave products to skin which are composed with thioglycolic acid and bases. Results were as follows. Permanent wave penetrated to 3 hours later with steady state in skins and was not significant changeable after 20hr later. In case of neutralizer with thioglycolic acid lag time and permeability coefficient in healthy skin were 3.32hr and $0.101{\mu}g/cm^2/hr$, in old skin were 3.08hr and $0.117{\mu}g/cm^2/hr$, and in wounded skin were 3.02hr and $0.166{\mu}g/cm^2/hr$. In conclusion, lag time and permeability coefficient in old skin and wounded skin were faster than healthy skin. In vivo, We were studied to general time and method of permanent wave. We found out that fine wrinkle and rash of skin were changeable in the case of treating with permanent wave drugs than normal skin.

Information collected on mobile devices might be utilized to support user's memory, but it is difficult to effectively retrieve them because of the enormous amount of information. In order to organize information as an episodic approach that mimics human memory for the effective search, it is required to detect important event like landmarks. For providing new services with users, in this paper, we propose the prediction model to find landmarks automatically from various context log information based on attributed Bayesian networks. The data are divided into daily and weekly ones, and are categorized into attributes according to the source, to learn the Bayesian networks for the improvement of landmark prediction. The experiments on the Nokia log data showed that the Bayesian method outperforms SVMs, and the proposed attributed Bayesian networks are superior to the Bayesian networks modelled daily and weekly.

This paper is divided into two parts. The first part elaborates on four Information Retrieval (IR) models: a traditional IR model and three more recent, user-oriented models of It interaction presented by Belkin, Ingwersen, and Saracevic. The strengths and limitations of each model are discussed. The second part, based on an analysis of the previous models, presents the author's interactive model, namely, the Iceberg Model. The rationales that are given to explain the design of this model are associated with the following: a greater specificity of system attributes; more concrete interplays among different components of IR interaction; and, the increased role of the Human Information Intermediary (HII). In sum, the new model presents a framework that can evolve in varying information-seeking contexts.

Purpose: While empirical importance of dimensionality of perceived value is widely accepted, our understanding of experiential value dimensions in other retail channels and other cultures has not been explicitly tested. This study attempted to determine if the dimensions of experiential value scale (EVS) by Mathwick, Malhotra, and Rigdon (2001) identified in US catalog and Internet contexts could be applied in other international markets (South Korea) and in other retail channels (department store versus Internet shopping mall). Methodology/Approach: Two data sets, one from 220 department store shoppers and the other from 359 Internet shopping mall shoppers, were analyzed. Findings: Confirmatory factor analysis confirmed four different EVS dimensions by retail channels. Overall, entertainment and intrinsic enjoyment values were found to be more important in department store while economic and efficiency value dimensions were interpreted critical in Internet shopping mall context. Visual appeal aspect constitutes distinct value dimension in two channels. Practical Implications: One separate dimension of time efficiency in Internet shopping mall suggests that more efficient web design and functions that can save time and promote convenience are needed to better accommodate their customers. Internet has heavily relied on traditional attributes, such as factual information, price comparability, and brand name reliance. However, this study suggests that Internet shopping mall retailer should offer visual diversion and stimulation just as brick and mortar shopping malls do. Originality /Value of Paper: Although the research findings must be viewed as tentative because the results are from one country, they provide a rich basis for further understanding the dimensions of experiential value in other international markets and other retail channels.

As the recent demand for human resources in science, technology, engineering, and mathematics (STEM), the development of professional STEM teacher is called worldwide. It is becoming a critical need in teacher education in order to educate student teachers, and prepare pre-service and beginning teachers for high quality of teaching competency. To promote the competency for $21^{st}$ century STEM teachers, the epistemology of technological pedagogical content knowledge (TPACK) is currently considered as the essential qualities of knowledge for highly qualified teachers. The aim of this study is explore the effect of case-based learning approach on TPACK competency of pre-service STEM teachers. In order to develop the pre-service teachers' competency regarding effective integration of technologies into teaching specific content areas, a series of innovative case study teaching in science and mathematics was presented to 43 participants of pre-service physics, chemistry, biology, mathematics, and computer teachers during a course of information and communication technology (ICT) in Education at Khon Kaen University, Thailand. After finishing a case presentation, the pre-service teachers were encouraged into a forum of critical open discussion by considering the potential impact of the case and the TPACK framework. They were investigated instructional design competency of using ICT tools into student learning process and their personal beliefs about ICT in educational process both before and after. The participant's reactions and learning was evaluated by using a self-reported questionnaire and an implementation log of content-specific learning process design, respectively. Results showed a change of their beliefs and the transformation of their TPACK competency in STEM teaching. In an effort to better serve the needs of high quality STEM teachers, the results of this study illustrated that the competency of TPACK could be particularly considered as a core attributes for future STEM teachers. By the way, case-based learning approach can play an effective part in preparing and professing the TPACK competency for STEM teachers.

This paper concerns professional socialization of medical students. Professional socialization, in the context of this paper, means the process through which a layperson becomes a doctor equipped with professional identity and values. While medical education does not include such process in the curriculum, medical students obtain certain values and identity informally. The dependent variables were professional values and professionalism. The former means the desirable attributes required to conducting professional works such as humane attitudes, science-oriented mind, capability for organizational management. The latter means socio-political reasoning with which doctors can rationalize their privileges such as autonomy. A specially designed questionnaire was developed. The data were collected from five medical schools for 1,318 students in 1994. A total of 1,070 cases were finally included in the statistical analysis. The students emphasized the human factor in the professional values. Their attitude did not change with the grade. Other independent variables such as motives for entering a medical school, socioeconomic status, satisfaction with medical education, etc. also did not influence professinal values. It implies that professional values were not consolidated among the students. However, the factors of professionalism change significantly with the grade. It implies that the students paid more attention to socio-political issues related to doctor's interests as the grade went up. And the factor scores for professionalism were higher for those students who had more positive attitude towards doing medical practice for profit, expected higher income, and were more conservative about social reform. Other independent variables did not influence professionalism. It seems that the students also give emphasis on professionalism, like current medical doctors, mainly because of their concern with recent unfavorable changes in economic conditions of medical care providers.
