Failure situations occur frequently in the industry, and the existing 2D-based manual for this purpose is not intuitive to understand and it is difficult to immediately interact with maintenance experts. In this paper, we propose a technology that enables workers to perform maintenance in real time with the help of experts without restrictions in time and place based on augmented reality when a failure situation occurs at a remote location. A local virtual human-based expert diagnoses a failure situation based on an adapted panoramic image of a remote failure situation while wearing an HMD headset, and gives instructions to a remote operator. In addition, in an augmented reality (AR) environment in a remote location, for the interaction between the operator and the expert, the HMD's microphone is used to create the expert's hand as well as verbal communication. You can use to point or draw a picture. If this technology is used, it is possible to overcome the limitations of the existing 2D-based manual, and to provide assistance in performing maintenance smoothly remotely even if an expert does not directly visit a remote location.

The purpose of this research is to understand interactive learning during docent-led tours in a science museum focusing on scaffolding. We developed a scaffolding framework by collating the work of other researchers in related fields. The results show that scaffolding included three dimensions: purpose, interaction, and domain. The purpose dimension, divided into six categories, is related to the intention of the scaffolder and what the scaffolding are for: strategic, social, procedural, conceptual, verbal, and metacognitive. The interaction dimension reflects students' interaction with the scaffolder in two ways: dynamic (situation specific) and static (planned in advance). The domain dimension is related to two contents: domain-general and domain-specific (such as science). The scaffolding framework was applied to dynamic interactions between docents and visitors. The data was collected from elementary school students' family visits with the guidance of two docents at the Seodaemun Museum of Natural History. The data collected consisted of surveys, interviews, video-recordings, and transcripts. The analysis shows that five guiding contexts and scaffolding phases were recognized; 1) strategic scaffolding in a poorly illustrated exhibit; 2) conceptual scaffolding in a thoroughly explanative exhibit; 3) verbal scaffolding in misleading interpretation; 4) procedural scaffolding in a manipulative exhibit; and 5) metacognitive scaffolding with inaccurate content. In addition, the results show that the docents used the dynamic and static scaffolding synthetically so that the docent-led tour was effective. In conclusion, this study presents the usefulness of understanding visitors' science learning through the scaffolding framework, as well as the how docents can scaffold actively.

This study was aimed at developing a scale to evaluate Korean home environments for infants and toddlers for the purpose of being used by teachers caring for infants and toddlers. The subjects of this study were 250 mothers of 0- to 2-year-olds. Mean, SD, $x^2$, Cramer's V, factor analysis, Pearson correlations, Cronbach's ${\alpha}$ were calculated in order to analyze the outcomes of this study. As a result, 38 items of the scale were found to be satisfactory in terms of item distribution and item discrimination. Four factors with 21 items were extracted from the factor analysis : 'developmental stimulus', 'responsivity', 'encouragement of verbal interaction', and 'arrangement of daily routines'. Our analysis of the correlation of this scale with SES, HOME, and children's developmental outcomes showed acceptable concurrent validity. Internal consistency of this scale was high. These results identify this scale as a valid and reliable measure of the Korean home environment for infants and toddlers.

It is the prime importance of the information and the reference-librarians to better understand the communication functions of the library since they are the ones to whom the library users come first with their informational needs. Reference librarians often have the problem of providing information to those who may have little experience with, or interest in the library. There is also a problem of finding out what the person really wants, not what he says he wants. Therefore, the interaction between the librarian and the user involves a highly complex activity of communication with each other even before the actual search begins. Reference librarians cannot perform to any degree of success without comprehension of the general patterns and processes of communication in information seeking. Nonverbal as well as verbal transmittal process on the part of both librarians and patrons should not be overlooked. Some of the difficulties and barriers of library communication are brought so that possible cures and improvement may be sought. The basic purpose of the reference interview through which this interpersonal communication takes place is for the reference specialist to enable to link the needs of the patron with potential resource of the library. The writer firmly believes that this importance of the process be taught as well as the materials in reference service regardless of the level of the course offered in library science department.

As the development of digital and technological sophistication, architectural speculation hierarchy had been more and further diversified and brought on the changes with system of architectural color meaning. Architectural color had been influences on evocation of effect and meaning by association, had the attributes of communication with human being, in common with precision, non-verbal and non-quantitative creative field. Color could not been defined as one conclusively standard symbol and figured out in inter-relationship with correlation, mental status and interaction. Color in architecture could been promptly defined as the tool of visualization in building or structure through the essential criterion to be measured with shape, space and author's thought. In consequence, color in architecture could been re-defined as the speculation concept for real characteristics creation(color as design factors on architect and color to be expressed by program) in itself, and color supporting system as for transposition of light and space enlargement scheme. Consequently, color in architecture could been turnover from perceived color to anthropological color through the real value creation scheme in itself.

The purpose of this study is to compare the complexity of language level between verbally-precocious and typically-developing children from 2 to 3 years-old. Participants were 15 children classified as verbally-precocious were scored at the mean 56.85(expressive language) and 88.82(receptive language), and another 15 children classified as typically developing did at the mean 33.51(expressive language) and 58.01(receptive language) on MCDI-K. Each child's spontaneous utterances in interaction with her caregiver were collected at three different times with 6 months interval. All of the utterances were transcribed and analyzed for the use of MLU and lexical diversity by using KCLA. Summarizing the overall results, verbally-precocious children had significantly higher language abilities than typically-developing children at each time, and there were significant differences between two groups in syntactic and semantic language development, showing that verbally-precocious children indicated distinctive MLU and lexical diversity. These results suggest a high degree of stability in precocious verbal status, with variations in language complexity during conversations contributing to later differences in their language ability.

The purpose of this study was to investigate the effects of different types of attentional focus(internal focus vs. external focus) on the dart throwing mechanics. Seven expert dart throwing athletes were assigned to an internal focus group and other seven athletes were assigned to an external focus group. Each group was asked to throw dart either under verbal instruction or without instruction. During dart throwing, accuracy(radial error), consistency(bivariate variable error), dart velocity, acceleration, elbow joint ROM, elbow joint angular velocity, EMD(electromechanical delay), iEMG of biceps brachii and triceps brachii, and CI(coactivation index) were collected and analyzed. Nither instruction type nor instruction itself affected in accuracy and consistency. However, in dart velocity and acceleration, there was an interaction between instruction and attentional focus types. Velocity and acceleration increased in the internal condition, where as they decreased in the external condition. The ROM of elbow joint did not affected by instruction and attention type. However, similar to dart velocity and acceleration, angular velocity increased in internal focus group, while it decreased in external focus group. EMG showed no difference with any condition. In conclusion, internal focus is better than external focus for dart throwing.

The purpose of the present research was to study (1) children's sex-stereotyped perception toward adult occupations, and (2) the impact of traditional sex-stereotypes on future occupational preference. The subjects of this study were 120 children, 3 to 8 years of age enrolled in kindergatens and elementary schools. The instrument was developed by the researcher and consisted of 10 occupations which are traditionally sex-typed in Korean society. 5 male and female sex-typed occupations were selected with the participation of 200 college students. These occupations were illustrated on 10 pictorial cards, and short verbal explanations were given for each of them. It was found that: (1) Levels of children's perception of occupational sex stereotypes show that children aged five to six are marked comparatively higher than those aged three to four in the perception of occupation, children of seven to eight age indicate slightly downward; however, they are not differed significantly from those of five to six. (2) As far as levels of children'5 perception of occupational sex stereotypes aged three to four, five to six and seven to eight are concerned, interaction between age and sex was not shown significantly. Female children were more stereotyped at almost all age levels. (3) Irrespective of sex and age, all subjects were more familiar with male than with female occupations. (4) in the choice of future occupations, boys as well as girls preferred sex-stereotyped occupations for themselves. Boy's choices were more stereotyped than girls', but the number of kinds of occupations chosen by boys and by girls was not different. (5) There was an increase with age in the number of children who gave future occupational choices.

This paper presents the concept of "interactive teleprompter", which provides the user with interaction with oneself or other users for live television broadcasts or smart mirrors. In such interactive applications, eye contacts between the user and the regenerated image or between the user and other persons are important in handling psychological processes or non-verbal communications. Unfortunately, it is not straightforward to address the eye contact issues with conventional combination of normal display and video camera. To address this problem, we propose an "interactive" teleprompter enhanced from conventional teleprompter devices. Our interactive teleprompter can recognize the user's gestures by applying infra-red (IR) depth sensor. This paper also presents test results for a beam splitter which plays a critical role for teleprompter and is designed to handle both visual light for RGB camera and IR for Depth sensor effectively.

The purpose of this study was to compare receptive language performance and expressive language performance in 13 patients with aphasia by using three stimulus presentation modes: Stimulus mode I (picture), Stimulus mode II (written word), Stimulus m (question using verbal explanation). The stimulus consisted of 10 words. They included 5 functional words and 5 non-functional words. The 13 subjects with aphasia were divided into 2 aphasic types: 5 Broca's aphasics and 8 anomie aphasics. The results were as follows: Firstly, the three stimulus modes didn't affect receptive language performance of aphasia subjects. Secondly; the three stimulus modes were effective on expressive language performance of aphasia subjects. Particularly, stimulus mode II (written words) was effective in naming the aphasia subjects. Thirdly, the functional words with high frequency were better than non-functional words with low frequency on expressive language performance, but not on receptive language performance of aphasia subjects. Finally, the interaction between three stimulus modes and the functional (nonfunctional) words affected expressive language performance only, but not receptive language performance. Particularly, presenting stimulus in written words which are functional words produced the best expressive language performance.
