This study was conducted to investigate the perception of teaching consulting and dietary education of Home Economics teachers. The subjects consisted of 139 Home Economics teachers in Korea. The perceptions of Home Economics teachers on their teaching class were as follows: the teachers who had a lot of psychological burden on their open classes, 62.6%; who were satisfied with their teaching, 29.5%; who had been teaching consulting, 40.3%; consulting is needed in order to improve the quality of instruction, 46.8%; who wanted to receive teaching consulting, 46.1%. who wanted to receive teaching consulting excellent colleagues, 76.3%. The most of the Home Economics teachers had a positive attitude on the teaching consulting. The perceptions of teaching strategies of dietary teaching classes were as follows: using audio-visual materials for students concentrate, 47.5%; observing the students reactions and feedback for individual variation, 73.4%; descriptive class for main teaching method, 58.3%. The difficulties of teaching dietary class were as follows: total mean, 2.60/5.00; considering individual differences, 3.26; involving students in activities, 3.11; selection of teaching media, 2.88; production of media, 2.88; planning teacher and student activities, 2.85. Home Economics teachers have to lead dietary education in society and schools but they feel a lot of psychological burden on opening teaching class. Therefore Home Economics teachers are recommended to devote consistent efforts to strengthen teaching ability through the analysis of teaching ability, teaching reflection, consulting and actual performance of self-supervision.

Amongst various methods of interpreting art, a understanding of the intention of artistic creation has been traditionally considered the most essential. Hermeneutics is the typical way of approaching it. With a focus on interpretation and understanding of the object, Hermeneutics delves into methodological techniques of interpretation and understanding of the existence of art from ancient Greece to the present. Nevertheless, from the Hermeneutic viewpoint, art as the object of interpretation is not free from social conditions and tradition; for this reason, interpretation of art basically has a socio-historical aspect. The starting point of this thesis is to examine the methods of understanding art from the socio-historical viewpoint. For this purpose, I study the theory of Hermeneutics as a basic of socio-historical interpretation of art, calling for methodology I need to justify inter-dependency of the epistemological viewpoint aid the ontological viewpoint in interpretation of art. Here, I suggest 'imputation(Zurechung)' and 'cycle(Zirkel)' as methodological concepts to support interdependency of these two viewpoints in Hermeneutics. Zurechung means explanation of meaning based upon the higher standard that includes to object of interpretation, while Zirkel means perception of part in order to understand the whole and, in turn, recognition of the whole in order to understand the part. These two concepts function inter-dependently in clarifying the object of interpretation and various problems of understanding human beings derived from it in the process of interpretation. This is also a key to the explanation that the object in social condition is closely related to historical perspective.

In this paper, the fast encoding algorithm in High Efficiency Video Coding (HEVC) encoder was studied. For the encoding efficiency, the current HEVC reference software is divided the input image into Coding Tree Unit (CTU). then, it should be re-divided into CU up to maximum depth in form of quad-tree for RDO (Rate-Distortion Optimization) in encoding precess. But, it is one of the reason why complexity is high in the encoding precess. In this paper, to reduce the high complexity in the encoding process, it proposed the method by determining the maximum depth of the CU using a hierarchical clustering at the pre-processing. The hierarchical clustering results represented an average combination of motion vectors (MV) on neighboring blocks. Experimental results showed that the proposed method could achieve an average of 16% time saving with minimal BD-rate loss at 1080p video resolution. When combined the previous fast algorithm, the proposed method could achieve an average 45.13% time saving with 1.84% BD-rate loss.

The computer hardware development has provided many chances of emergence between art and technology. In many cases today's interactive artworks cannot be completed without audience's participation. The interactive production process with technical supplementation can be celled feedback. Mr. Nam Jun Paik showed 'Participant TV' that interacts with audience's response in real time. It means artwork changes with the constantly changing value from the data set from human visual perception. Dan Graham showed another feedback related work, which delays 5second playback in mirror that implies consequence of time. Today's media art has to sublimate coincidence, time ant audience into philosophical artwork through consonance that comes with video and sound as we can see from Bill Viola. Stelarc produced artworks. That use input data that is weak signals from brain, muscles. Through a terminal display with player, body expanded meaning of media. Jeffrey Shaw's 'Legible City' provided a fabrication of the reality with the interaction of bicycle's pedal speed and steering direction that is controlled by 4river. RE:MARK used microphone as input device as Edmond Couchot's 'Je same a la vent' and Nam Jun Paik's 'Participant TV' did. There is no communication without feedback between human being. The reality makes audience involved into artworks. That is the reason why feedback has to be natural. Through the feedback process, the originality of the idea is altered by audience. The feedback is not just part of flesh of artwork rather skeleton of it. Technological showoff cannot be art itself The perfection of technological application plan helps feedback that interacts with audience naturally in order that audience hoes not feel the feedback as artificial plan. Interactive media art has to be evolved into new media form with new integration feedback technology.

The café has become an important representative "third place" where people study and rest. Hence, it is worthwhile for researchers to understand the needs of individual users as well as the requirements of people who visit such venues in groups. The identification of strategies that can help achieve larger, wider, higher, or deeper interior spaces in small and compact locations can generate benefits for both users and designers. In this study, where 56 interior design students participated, we used an eye-tracker and images of cafes to explore the relationships between spatial depth and the intention to visit a cafe space. The researchers digitally developed fifteen different conditions of space and measured the eye movements of the participants using an eye-tracker when they examined images that appeared to convey the most depth. Participants were also asked to imagine the proposed space images as cafes and to select one of the 15 images as the location that they would be most likely to visit individually and one that they would frequent in the company of other people. The research results revealed that certain ways of using interior design elements altered the participants' perceptions of spatial depth without any change being effected to the actual volume or the size of the space. The participants tended to perceive a space with a small decorative artwork on a dark toned wall with unconnected furniture as deeper than a space with no or large artwork on a light toned wall with contiguous furniture. Spatial depth was a more important consideration for an individual visit than for a group visit. The results of this exploratory study will help scholarly understanding of the role played by spatial depth in customer intentions to visit a cafe.

Purpose : The purpose of this study was to provide the material about the treatment effect of hand function training and writing training being performed as a part of treatment to improve the function of the non-dominant hand of the patients whose dominant hand is damaged and thus need to improve their non-dominant hand's function. Method : During one month of November, 2013, this study randomly chose five study subjects for hand function training, five for writing training, and ten of control group from 20 normal male and female adults going to K Univ. in Busan. All study subjects fully understood all of the training course, agreed to take the test in this study, and volunteered to participate in the test. Each training was performed five times for two weeks, 30 minutes each time. For measurement, Purdue pegboard was used to look into the change of hand dexterity. To investigate an improvement in hand function through hand function training and writing training, this study conducted early evaluation before training, interim evaluation, and final evaluation. Result : First, according to the comparison of dominant hand dexterity by group and by method during a training period, the groups of hand function training and of writing training improved dominant hand dexterity more than the control group. Secondly, according to the comparison of non-dominant hand dexterity by group during a training period, the groups of hand function training and of writing training improved dexterity more than the control group. According to the comparison of non-dominant hand dexterity by method during a training period, there was no big difference in dexterity between the groups of hand function training and of writing training and the control group. But, the group of hand function training showed a further improvement. Thirdly, according to the comparison of both-hand dexterity by group and by method during a training period, the groups of hand function training and of writing training improved both-hand dexterity more than the control group. Fourthly, according to the comparison of both-hand handling ability by group and by method during a training period, the groups of hand function training and of writing training improved both-hand handling ability more than the control group. Conclusion : Given the study result, it is considered that hand function training and writing training help brain damaged patients improve their hand function for their daily activity. And it will be meaningful to research brain damaged patients' motor skills after their brain damage, and the patients who have low abilities of visual perception and cognition. In the future, it will be necessary to secure more study subjects and perform systematic training during a sufficient test period.

Purpose: The current study was performed to compare the difference in binocular visual function depending on variable background colors at near work. Method: Fifty four adults (18 males, 34 females) who consented to the present study and had no ocular disease, ocular surgery history, strabismus and amblyopia with normal binocular vision were participated into this study. The subjects were asked to read the novels with black letter printed on white, red, green and blue background for 15 min. Then, their heterophoria, AC/A ratio, near point of convergence, accommodation facility, relative accommodation and vergence were measured before and after reading. The difference of measurements were compared. Result: Overall heterophoria was tended to decrease with regardless of background color. AC/A ratio showed a tendency of increase after reading the novels with all backgrounds except white background. Near point of convergence was significantly increased compared to before reading at all background color. Accommodative facility of dominant and non-dominant eyes were also significantly increased after reading however, binocular accommodative facility showed a tendency of decrease. Negative relative accommodation also decreased at all background colors however, the change of positive relative accommodation was not significantly different. In case of vergence, there was significant difference in break point of far BO and recovery point of far BI by the wavelength of background color. Conclusions: From the results, it was known there is convergence change depending on the wavelength of light even though same amount of accommodation and convergence is required when doing near work for certain period. Thus, it can be suggested that the adjustment of the near working environment which perception of various color was required, should be conducted according to the main wavelength.

Among the approaches to image database management, content-based image retrieval (CBIR) is viewed as having the best support for effective searching and browsing of large digital image libraries. Typical CBIR systems allow a user to provide a query image, from which low-level features are extracted and used to find 'similar' images in a database. However, there exists the semantic gap between human visual perception and low-level representations. An effective methodology for overcoming this semantic gap involves relevance feedback to perform feature re-weighting. Current approaches to feature re-weighting require the number of components for a feature representation to be the same for every image in consideration. Following this assumption, they map each component to an axis in the n-dimensional space, which we call the metric space; likewise the feature representation is stored in a fixed-length vector. However, with the emergence of features that do not have a fixed number of components in their representation, existing feature re-weighting approaches are invalidated. In this paper we propose a feature re-weighting technique that supports features regardless of whether or not they can be mapped into a metric space. Our approach analyses the feature distances calculated between the query image and the images in the database. Two-sided confidence intervals are used with the distances to obtain the information for feature re-weighting. There is no restriction on how the distances are calculated for each feature. This provides freedom for how feature representations are structured, i.e. there is no requirement for features to be represented in fixed-length vectors or metric space. Our experimental results show the effectiveness of our approach and in a comparison with other work, we can see how it outperforms previous work.

When analyzing soft tissue of the profile, Subnasale is often used as an important reference point. But there are few studies on the ideal position of the Subnasale. Therefore, the purpose of this study is to present an objective reference of the esthetic face relating to the change of Subnasale position in Koreans' profile, and also to determine whether there is concordance between professionals and laypersons in their perception of facial attractiveness. The one determined as appropriate profile portion by experts of pictures taken in women in 20s was selected. The photograph was modified changing the Subnasale anteroposteriorly on the plane perpendicular to the true vertical line, while maintaining the nasolabial angle. The photographs were presented to a group of professionals (9 orthodontists) and 126 laypersons, who were asked to assess the facial attractiveness of the photographs on a VAS independently. The conclusion was obtained. 1. The ideal position of the Subnasale is when the ratio of the distance Lateral canthus~Subnasale : Subnasale~Pronasale is 1.769 : 1. 2. The ideal degrees between the true vertical line passing through Nasion and Subnasale is $5.5^{\circ}$ 3. The professionals recognized every change in the ratio, but the laypersons couldn't differentiate between the change from 1.571 : 1 to 1.769 : 1.
