This research has an objective of investigating the challenges that student teachers encounter during practicum, the difference between teachers' image based on sociodemographic variables, recognition and satisfaction for practicum, and the effect of teachers' image and practicum experience on the satisfaction for the practicum. The participants of this study included 500 student teachers who enrolled in the department of early childhood education in a 2 or 3-year college or a 4-year university and completed practicum in the Chungcheong area. The instruments for this study were Teacher's Image Scale, Practicum Experience Scale, Practicum Satisfaction Scale and a questionnaire for sociodemographic variables. The results were as follows: First, the highest level of teachers' image was obtained for student teachers enrolled in a 2-year college, completed practicum in large cities and finished practicum at an institution with a size of 3-6 classes. Also, the highest level of 'recognition for practicum' of student teachers was observed when they were instructed by a guidance teacher with a degree from a graduate school and with a first degree certification in public kindergarten. Second, the satisfaction for practicum of student teachers was mostly affected by' the atmosphere of the practice institutions', while personality affected the teachers' image.

The objective of this study was to analyze the actual situation of ethics management in foodservice industry and its employees’ recognition on corporate ethics management. Self-administrated questionnaires were completed by 342 employees, and the data were analyzed by frequency, chi-square, t-test, and one-way ANOVA. The results showed that the employees consider the corporate ethics management to be very important and it has been much more improved in foodservice industry. However, they are still skeptical about the continuous and consistent practice of ethics management. In addition, the survey revealed that the ethics management was regarded to be critically important to improve the value and the culture of the corporation. It also showed that the recognition of the improvement of ethics management in foodservice industry has been affected by the work environment of the whole society too. The result concluded that the taking the initiative by CEO is the most important factor for introducing the ethics management, while the propagation of ethics management requires the volition of the employees inside the corporation.

The majority of construction site incidents occur due to a lack of hazard awareness among workers on job sites. This lack of awareness is despite mandatory construction safety training, typically in the form of written content (safety manuals) or of images depicting hazards. To reduce job-site injuries and fatalities, general contractors have started adopting Virtual Reality (VR) to impart safety training to job site personnel. VR safety training can take the form of an immersive simulation comprising potential safety hazards intentionally embedded into a virtual job site; users are required to identify these hazards within a specified time frame with the expectation that they will be more adept at recognizing hazards on an actual job-site, resulting in fewer accidents. This research study seeks to identify the actual impacts of VR on construction safety awareness among participants. The research addresses the following question: Does VR improve hazard recognition awareness? The primary objective is to evaluate participants' performance of past construction safety awareness against present construction safety awareness after receiving VR training. Participants were asked to complete a multiple-choice Qualtrics™ questionnaire. The results of the study showed a statistically significant knowledge gain advantage with respect to hazard recognition and construction safety awareness with the use of interactive, immersive VR over a more conventional and passive safety training method.

The purpose of this study is to investigate and analyze high school girls' observational characteristics. A total of 77 female high students were asked to observe 'Las Meninas', a well known 17th century painting by Diego Velazquez and volumetric flask. MBTI(Myer Briggs Type Indicator) was implemented for student's personal characteristics. We analyzed testimony into its differences between objective and practical, and subjective and abstract, wholeness by character type. As a result, 41 participants have preference for sensuous recognition and the rest of the 36 participants have preference for intuitional recognition. From the observation statement, it showed differences of the results according to their character type. As the result that it showed above, learners used two ways of recognition but they showed tendency with strong reliance on their preferred recognition. In case of preferring the sensuous recognition, it tended towards the basis of phenomenological analysis, objective fact and physical judge. However, in case of preferring the intuitional recognition, it tended to observe by momentary thinking, flash of idea and meaning behind.

In this paper, we describe a robot endeffector recognition system based on a Modular Neural Networks (MNN). The proposed recognition system can be used for vision system which track a given object using a sequence of images from a camera unit. The main objective to achieve with the designed MNN is to precisely recognize the given robot endeffector and to minimize the processing time. Since the robot endeffector can be viewed in many different shapes in 3- D space, a MNN structure, which contains a set of feedforwared neural networks, can be more attractive in recognizing the given object. Each single neural network learns the endeffector with a cluster of training patterns. The training MNN patterns for a neural network share the similar characteristics so that they can be easily trained. The trained UM is les s sensitive to noise and it shows the better performance in recognizing the endeffector. The recognition rate of MNN is enhanced by 14％ over the single neural network. A vision system with the MNN can precisely recognize the endeffector and place it at the center of a display for a remote operator.

Automobile black boxes store and provide accident and driving information. The accident and driving information can be utilized to build scientific traffic-event database and can be applied in various industries. The objective of this study is to develop a recognition system of dangerous driving through analyzing the driving characteristic patterns. In this paper, possible dangerous driving models are classified into four models on the basis of vehicle behaviors(acceleration, deceleration, rotation) and accident types from existing statistical data. Dangerous driving data have been acquired through vehicle tests using automobile black boxes. Characteristics of driving patterns have been analyzed in order to classify dangerous driving models. For the recognition of dangerous driving, this study selected critical value of each dangerous driving model and developed the recognition algorithm of dangerous driving. The study has been verified by the application of recognition algorithm of dangerous driving and vehicle tests using automobile black boxes. The presented recognition methods of dangerous driving can be used for on-line/off-line management of drivers and vehicles.

Background and Objectives: Although many studies have evaluated the effect of the digital noise reduction (DNR) algorithm of hearing aids (HAs) on speech recognition, there are few studies on the effect of DNR on music perception. Therefore, we aimed to evaluate the effect of DNR on music, in addition to speech perception, using objective and subjective measurements. Subjects and Methods: Sixteen HA users participated in this study (58.00±10.44 years; 3 males and 13 females). The objective assessment of speech and music perception was based on the Korean version of the Clinical Assessment of Music Perception test and word and sentence recognition scores. Meanwhile, for the subjective assessment, the quality rating of speech and music as well as self-reported HA benefits were evaluated. Results: There was no improvement conferred with DNR of HAs on the objective assessment tests of speech and music perception. The pitch discrimination at 262 Hz in the DNR-off condition was better than that in the unaided condition (p=0.024); however, the unaided condition and the DNR-on conditions did not differ. In the Korean music background questionnaire, responses regarding ease of communication were better in the DNR-on condition than in the DNR-off condition (p=0.029). Conclusions: Speech and music perception or sound quality did not improve with the activation of DNR. However, DNR positively influenced the listener's subjective listening comfort. The DNR-off condition in HAs may be beneficial for pitch discrimination at some frequencies.
