New images percolate through human consciousness by the media such as movies, TV programs, and brilliant advertisements. These images reproduce new ' things ' throughout the ' semantic processes ' by those who experience and recognize them. Alvin Toffler describes it as the ' information bomb ' and ' image fragments ' in his talk about the new paradigm of information-oriented era. The increasing number of images and their accelerating rate of appearance imply that images become more momentary, and are evidence that they are transforming entire human life and consciousness. Such awareness means a lot to a designer. Especially, the subject that how modern space-dominating images are related to the structure and materials constituting the space and communicate with human mind will be an important factor in establishing the human-space relationship in the future. Furthermore, the present age overspread with various medium is not the only one privileged of the images that exist within space. They are the results of continuous expansion of existing images, and also process of evolution of space powered by the fusion of images and digital media. Imagified space is a boundary layer of Cyberspace, and the space itself becomes an interface by human recognition and participation. Now, the functional classification of spaces such as ' office, ' ' cafe, ' and ' school ' is meaningless. Whatever it may be, the function of a space is defined by the information it interfaces, and therefore it becomes an interface to information through a large number of images. Based on this idea, we will observe the imagificaiton of space in the form of discussion, and from that, try to understand the phenomenon through the real world examples.

We have developed a wearable device that can convert sensor data into real-time step counts. Sensor data on gait were acquired using a triaxial accelerometer. A test was performed according to a test protocol for different walking speeds, e.g., slow walking, walking, fast walking, slow running, running, and fast running. Each test was carried out for 36 min on a treadmill with the participant wearing an Actical device, and the device developed in this study. The signal vector magnitude (SVM) was used to process the X, Y, and Z values output by the triaxial accelerometer into one representative value. In addition, for accurate step-count detection, we used three algorithms: an heuristic algorithm (HA), the adaptive threshold algorithm (ATA), and the adaptive locking period algorithm (ALPA). The recognition rate of our algorithm was 97.34% better than that of the Actical device(91.74%) by 5.6%.

Journals are the main indicator to evaluate the level of the studies of a country. The main purpose of this study is to suggest the improvements of the current journal evaluation system to enhance the level of journal quality. To accomplish the above purpose, the 631 researchers are surveyed by internet for their recognition. The major findings are as follows. Firstly, the current registration process need to be maintained, however, need to reinforce the conditions to level up the journal level and to extend the term for keeping the rate. Secondly, the professionalism and credibility of the appraisers need to be reinforced to increase the equity and rationality of the current evaluation system. Thirdly, the evaluation process for the newly entering journal need to be more strict than the current system. Fourthly, the Korean citation index or Kor-Factor need to be applied to evaluate the domestic journals. Lastly, the restriction policy is need to constrain the number of journals.

This study aims to examine the effects of native advertising on consumer-brand relationship quality (BRQ) formation of the potential consumers in the context of an automotive brand. Specifically, the study verifies (1) whether the respondents cognize the content of native advertisement as an advertisement and (2) how the value dimensions of native advertising impact BRQ through brand attitude (BAT). To fulfill the purposes, the researchers categorized three types of advertisements (product, brand and non-commercial) and then showed three manipulated stimuli to potential consumers in the automotive market before measuring. The findings drawn from the 345 valid cases are as following. First, the rate of respondents' advertising recognition is low in the non-commercial advertisement, while it is high in ones of product and brand. Second, most of the respondents perceive less irritation toward the native ads, especially toward the non-commercial advertisement. Third, the entertainment and informativeness of native advertising positively influence BRQ, while the effect of irritation on BRQ is negative. Also, the effects of advertising value dimensions on BRQ are all mediated by BAT.

Eye localization is necessary for face recognition and related application areas. Most of eye localization algorithms reported thus far still need to be improved about precision and computational time for successful applications. In this paper, we propose an improved eye localization method based on multi-scale Gator feature vector models. The proposed method first tries to locate eyes in the downscaled face image by utilizing Gabor Jet similarity between Gabor feature vector at an initial eye coordinates and the eye model bunch of the corresponding scale. The proposed method finally locates eyes in the original input face image after it processes in the same way recursively in each scaled face image by using the eye coordinates localized in the downscaled image as initial eye coordinates. Experiments verify that our proposed method improves the precision rate without causing much computational overhead compared with other eye localization methods reported in the previous researches.

This study tried to investigate the differences between auditory preferences for a discrimination study of minimal pairs with the different onset and the same nucleus of a syllable on the basis of articulator-distance in case of Korean infants and toddlers. As a result we found a main effect for articulator-distance and age but not an effect according to the types of phonation especially in terms of tense. Former results are line with the previous studies having reported the order of consonants acquisition based on the places of articulation suggesting that more sensitive responses for the contiguous and different phonemes may lead earlier acquisition for the same place of articulation of the speech sounds. Specifically, bilabial soudns are followed by alveolar and palatal sounds in order. The latter results also showed that tense consonants got a high rate of recognition beside lax consonants according to the age and sex.

In this paper, we developed a visual-auditory cue software for reading training of motor speech disorder patients. Motor speech disorder patients can use the visual and/or auditory cues for reading training and improving their symptom. The software provides some sentences with visual-auditory cues. Our sentences used for reading training are adequately comprised on modulation training according to a professional advice in speech therapy field. To ameliorate reading skills we developed two algorithms, first one is automatically searching the starting time of speech spoken by patients and the other one is removing auditory-cue from the recorded speech that recorded at the same time. The searching of speech starting time was experimented by 10 sentences per 6 subjects in four kinds of noisy environments thus the results is that $7.042{\pm}8.99[ms]$ error was detected. The experiment of the cancellation algorithm of auditory-cue was executed from 6 subjects with 1 syllable speech. The result takes improved the speech recognition rate $25{\pm}9.547[%]$ between before and after cancellation of auditory-cue in speech. User satisfaction index of the developed program was estimated as good.

This paper presents a method of location sensing of mobile objects using RF devices. By analyzing signal strengths between a certain number of fixed RF devices and a moving RF device, we can recognize the location of a moving object in real time. Firstly, signal strength values between RF devices are gathered, and then the values are normalized and constructed as a model feature vector for specific location. A number of model patterns are acquired and registered for all of the location which we want to recognize. For location sensing, signal strength information for an arbitrary moving RF device is acquired and compared with model feature vectors registered previously. In this case, distance value is calculated and the moving RF device is classified as one of the known model patterns. Experimental results show that our methods have performed the location sensing successfully with 100% rate of recognition when the number of fixed RF devices is 10 or more than 12. In terms of cost and applicability, experimental results seem to be very encouraging.

Even though the automation of industrial machinery has dramatically increased, most industries still require human hands for the production of goods. Our hands are essential to our existence. For this reason, hand injuries caused by industrial accidents have become an important issue lately. Most hand injuries are external wounds and constitute 38.6% of disabling industrial accidents. This significant statistic cannot be ignored by rehabilitation programs. The rate of success in operations of finger and hand injuries has increased, but relatively less consideration has been given to physical therapy, rehabilitation, research, or systematic installment in terms of welfare, which would help the injured carry on the nominal life they lived before their injury. Therefore, it is necessary to study systematically all related aspects to provide patients with physical therapy, rehabilitation, and social welfare, in order to restore their social, professional, and economical capabilities. Physical considerations, functional usability, and cosmetic restoration, as well as the patients' mental state must be addressed. The results of the study shows several problems. Medical appliances, manpower, and the environment of the treatment rooms are very poor. The patients cannot receive treatment early enough nor enough treatment because of too many patients for too few physical therapists. Close cooperation between physical therapists and doctors, nurses, or related departments is lacking. Furthermore, it is irrational that industrial accident premiums for the exert; e treatment of hand injury patients are not itemized. Lack of recognition of the importance of specialty in hand injury therapists leads to the lack of professionalization of systematic hand injury treatment In order to solve these problems, the professonalism of physical therapy should be acknowledged and particular treatment courses should be available and/or required. Based on the understanding of the hand injury patients' needs, new theories of physical therapy should be developed and modem medical appliances and facilities should be available, in order to provide the patients with qualitative medical treatment, which then will facilitate the patients' recovery.

According to the participants, the current K-MOOC (Korean Massive Open Online Course) has a few problems, such as too few courses, low content quality, and useless learner management system compared to MOOCs abroad. These problems caused diminished learner motivation. Consequently, the K-MOOC service has recorded a low course completion rate despite high expenses spent to develop the contents and thus requires remedies to fix the issues. This study drew research subjects from a pool of college and graduate students representing the primary users of the K-MOOC. This study limited the research scope to the four categories: motivation, learning experience, recognition, and performance of the Biggs' 3P Learning System Model. Based on the literature review, ten variables were selected and explored how the subjects perceived four categories using the survey questionnaire. This study also examined the relationship between ten variables and generated suggestions for the instructors, course managers, and platform developers to make the K-MOOC better.
