The purpose of this study is to research pre-service chemistry teachers' inquiry ability and perception on inquiry by analyzing their argument structure. Nine graduating senior students have participated in this study. They have experimented with mass change during state change, which is included in 7th grade science textbook. We have analyzed pre-service teachers' experimental reports using Toulmin's argument model. Also, we have researched their views on science and experiments through questionnaires and semi-structured interviews. As results show, various factors have affected pre-services' argument structures; lack of science knowledge and inquiry ability, belief about error, and additive data. This study shows that pre-service teachers' inquiry abilities is insufficient, and it is necessary to review rearrangement of pre-service science teacher curriculum in order to offer inquiry experiments in teacher education program.

Objectives Schizophrenia is characterized by disturbances in perception and cognition. Attenuated mismatch negativity (MMN) reflects central auditory dysfunction in schizophrenia. The aim of this study is to compare MMN changes before and after treatment in schizophrenia patients and to assess their association with treatment response. Methods Twenty-three schizophrenia patients underwent an oddball paradigm. MMN was calculated by the difference waveforms of the event-related potentials (ERPs) elicited by subtracting standard from deviant stimulus. The clinical symptoms were measured by the Positive and Negative Syndrome Scale (PANSS), the Psychotic Symptom Rating Scale (PSYRATS). Follow-up evaluation was conducted when the PANSS total score decreased by 30% or more (treatment response group) or before discharge (non-response group). Results The treatment response group showed significantly larger MMN amplitude improvement and latency reduction than the non-response group after treatment (Fz ; mean amplitude p = 0.035, FCz ; p = 0.041). The auditory hallucination group showed shorter latency than that of the group without hallucinations. Additionally, auditory hallucination was associated with prolonged MMN latency and shortened after treatment in the auditory hallucination response group (Fz ; p = 0.048). Conclusions These results suggest that the attenuated MMN amplitude reflects the progression of the disease. The increment of MMN amplitude and shortening of latency after treatment may reflect cognitive functional recovery of central auditory sensory processing.

In this paper, we present a distortion correction for wearable Augmented Reality (AR) on mobile phones. Head Mounted Display (HMD) using mobile phones, such as Samsung Gear VR or Google's cardboard, introduces lens distortion of the rendered image to user. Especially, in case of AR the distortion is more complicated due to the duplicated optical systems from mobile phone's camera and HMD's lens. Furthermore, such distortions generate mismatches of the visual cognition or perception of the user. In a natural way, we can assume that transparent wearable displays are the ultimate visual system which generates the least misperception. Therefore, the image from the mobile phone must be corrected to cancel this distortion to make transparent-like AR display with mobile phone based HMD. We developed a transparent-like display in the mobile wearable AR environment focusing on two issues: pincushion distortion and field-of view. We implemented our technique and evaluated their performance.

This research studied the development of high functional wear that reflects the various needs of an aged population. A survey of the life style, body functions and body changes, cognition, and preference of high functional wear with a subject group of 342 women aged 50's-60's was conducted. The results show that these women showed a high interest in clothing, challenged to new tasks, and enjoyed social meetings. Women aged 50's and 60's showed a relatively vibrant and active tendency, with no difference between them. They had the most interest in health and diet. The development of various clothing items and designs for women in their fifties and sixties are required because exercise was the most favored leisure activity. Meanwhile, they showed indisposition according to body type changes and the decrease in body functions. There was also some discomfort due to changes in visual power and trouble in controlling the body temperature. Therefore, the need to develop high quality smart wear that can help improve these problems was raised. Women aged 50's to 60's did not fully understand smart clothing; however, they showed some interest in high quality smart wear designed to improve health conditions after they heard detailed explanations about the clothing. They perceived the matter of laundry or managing he clothing more important than the price or rejection to mechanical device in regards to smart wear.

Despite the recent importance of interdisciplinary convergence research, little has been studied on the detailed experience while conducting convergence research in Korea. To deeper understand challenges and overcoming in convergence research and to suggest an administrative system for it, by analyzing researchers experience and cognition while conducting their actual convergence research, in-depth interviews with 16 full-time faculty members with expertise in convergence research and research administration in a university and analyzed the interviews by using the paradigm model of grounded theory. The results show that the core phenomenon researchers experienced is that "convergence research is not being effectively conducted," and they experience growth in research through pursuing efforts and improving research atmosphere in various aspects. Based on these findings, we made several suggestions for promoting convergence research.

The purpose of this research is to increase understanding about 'an attitude' and to develop the contents of the reading attitude survey questionnaire through the analysis and comparison of reading attitude models. An attitude has an individual's perception and feeling about events, problems, people or things, and it also includes the state prepared for reaction. An attitude consists of emotion, cognition and behavior and it is formed by experience, learning or value judgment. Reading attitudes are composed of cognitive factors that represent beliefs or opinions about reading, emotional factors that represent evaluation and emotion about reading, and behavioral factors that represent intentions or behavior to reading. The analysis of the components of the reading attitude models shows the fact that the influencing factors of reading attitude formation are the reading experience, beliefs of reading results, beliefs about others' expectations and reading environments. Thus, the contents of reading attitude survey questionnaires should include such contents as reading experience, beliefs of reading results, beliefs about others' expectations, and reading environments.

The purpose of this study was to analyze Olympism. For analysis, a Q methodology was applied, which is useful for identifying individual's subjectivity structure. The research question raised in this study included what is Olympism. For this study, a Q-sample, which made 34 statements exploring the Olympism attitude and value system, was used. In addition, a P-sample was composed of 35 statements. Seventeen people with non-physical education involvement and 18 athletic players were selected. Olympism was categorized into five types: 'traditional values', 'meaningful to participate', 'contend for victory', 'fair play', and 'sense of ethics'.

This study will be conducted to verify that color programs and entertainment programs affect undergraduates' psychology(Obsessive-compulsive, anxiety and hostility). The results of this study can be summarized as follows. First, the experimental group's psychology(Obsessive-compulsive, anxiety and hostility) participated in color programs than did all the pre-investigation levels decreased post-mortem examination, statistically significant at 95% appeared to be. Second, after watching entertainment programs, pass through cognition process of color, undergraduates' color representation worked perception of red and blue respectively. This results is that the reason of white and the suppression of black what to do now with a sense of responsibility can be considered as a change process. In conclusion, after watching entertainment programs take advantage of color programs that a positive impact on undergraduates' psychological state, as they can provide bright colors with a variety of ways that make sense to suggest.

Exhibition space emphasizes the experience in the space rather than viewing or appreciation of visitors. Because the experience spaces in today's life are limited, people experience rest, comfort, and sometimes extraordinary space experience through exhibition space. Exhibition space has changed from a static place to a space where visitors move and act with the exhibits to freely feel the space. Also, the static space expressed only with illumination and shadow becomes a new space different from daily space for users. This study analyzes the characteristics of phenomenological expression through such user-oriented exhibition space. This study is to analyze the characteristics of phenomenology through the exhibition experience space structure. It is to analyze and study on the characteristics of phenomenological expression of the exhibition experience space structure centered in the opinion of Merlo-Ponti that considers the experience of body among 'characteristics' discussed based on the study of the phenomenological experience published up to date and the viewpoint of Steven Hall that sees light as a subject of creating the space. This study is also considers how the perception of the experiencer is built in the correlation between the phenomenology and exhibition experience space by studying the relationship of the experiencer that is the common point of the exhibition experience space structure and the characteristics of phenomenological expression and analyzing the common point and difference of them. It also focuses on the space of dark whether forming any light rather than looking at the light which is the sense factor among the characteristics of phenomenological expressions. Thus, the purpose of this study is to analyze the case on whether there is any light or not applied to the exhibition experience space grounded by the theoretical materials of Merlo-Ponti and Steven Hall based on the characteristics of phenomenological expressions in the exhibition experience space structure and, based on the result, to set up the basics on the characteristics of phenomenological expressions in the composition of exhibition experience space.

PURPOSE: This research was designed to study the correlations between physical activities such as foot sensory impairment, balance and ambulatory abilities, as well as fall risk factors and mental activities such as cognitive performance and depression in order to provide fundamental data for the prevention of falling in the elderly. METHODS: A total of 36 elderly people over the age of 65 years who voluntarily joined the research were selected as subjects. Sensory perception in both feet was measured by using a monofilament in 10 parts with each part given one point. The points for each foot were integrated to analyze the correlations between physical and mental activities indices, and the results were analyzed by using Pearson's correlation coefficient. RESULTS: The results of this research show that the extent to which senses in feet were impaired was correlated to TUG, a functional activity index involved in tranfers, gait, and turning movements, which was correlated to BBS (balance index) as well as MMSE-K and K-GDS (mental activities index). BBS was interrelated to FES-K (physical activities index) and MMSE-K. The muscular strength of the right ankle dorsiflexor had mutual relations with FES-K. CONCLUSION: The results of this research indicate that TUG is widely correlated to foot sensory impairment as well as general physical and mental activities in elderly people. BBS was also shown to be correlated with TUG, FES-K, and MMSE-K. Thus, it might be necessary that TUG and BBS be included as two items in physical and mental check-ups for the elderly, and further studies on correlations using evaluation items for physical and mental activities should lead to the simplification of the evaluation criteria.
