The reliability of a Bridge management System depends on the quality of visual inspection and the reliable estimation of bridge condition rating. However, the current practices of visual inspection have been identified with several limitations, such as: they are time-consuming, provide incomplete information, and their reliance on inspectors' experience. To overcome such limitations, this paper presents an approach of automating the prediction of condition rating for bridges based on digital image analysis. The proposed methodology encompasses image acquisition, development of 3D visualization model, image processing, and condition rating model. Under this method, scaling defect in concrete bridge components is considered as a candidate defect and the guidelines in the Ontario Structure Inspection Manual (OSIM) have been adopted for developing and testing the proposed method. The automated algorithms for scaling depth prediction and mapping of condition ratings are based on training of back propagation neural networks. The result of developed models showed better prediction capability of condition rating over the existing methods such as, Naïve Bayes Classifiers and Bagged Decision Tree.

This study was conducted to find out the proper ways of implementation of Hazard Analysis Critical Control Point (HACCP) concepts applicable to the current Korean food inspection system. The following recommendations are based on an in-depth review of the Canadian Food Safety Enhancement Program (FSEP), which is one of the leading HACCP programs adapted to the food industry. Since 1997, the HACCP system has been voluntarily applied to meat processing plants in Korea in accordance with the Food Protection Law. But the guidelines are obscure and inadequate to expand to the diversity of food plants, and are therefore only applied to a limited number of plants of small scale enterprise. For these reasons, it is necessary to prepare an enhanced food safety control program focused not only on the HACCP plants but also on the non-HACCP plants. The national program should be the fundamental framework of a food safety control policy enforced by all the relevant authorities. The Prerequiste Program of Canadian Food Inspection Agency and Sanitation Standard Operating Procedures (SSOP) of FSIS are good example programs for the non-HACCP plants. These programs, which are a major part of the HACCP system, could easily be adapted to the Korean food industry. To improve the current HACCP implementation guideline, it is necessary to develop a detailed implementation manual, generic HACCP model, training program, and an audit program.

The aim of this study was to investigate school dieticians' awareness of the necessity for nutritional education and job satisfaction via qualitative research. For this purpose, in-depth interviews were carried out with 10 school dieticians. Results revealed that all participants said that schools urgently need nutritional education, and dietary attitude and unbalanced eating habits were the most urgent matters to be addressed. They made various suggestions related to revitalization of nutritional education: turning dieticians into nutritional educators, improving awareness of teachers and parents, receiving training on appropriate teaching methods, and so on. In response to their tasks, they considered bargaining with vendors and examination foods as the most burdensome tasks. In response to questions about how participants were treated in their workplaces, all participants reported low job satisfaction due to excessive work, lack of promotion opportunities, and low salary. To improve this, participants recommended creating a task manual, strengthening their role as managers, increasing their salary, and so on. Therefore, institutional support is necessary for dieticians to efficiently handle their excessive workload. In addition, an educational environment where dieticians can effectively carry out nutritional education needs to be created.

The purposes of this study were to examine: 1) supporting activities of fashion brands for store-level visual merchandising(VM); 2) shop masters' attitude to VM supporting activities; 3) the differences in the perceived importance of VM, attitude to VM supporting activities, and shop masters' VM management by shop master characteristics; and 4) the influencing factors on shop masters' VM management. A total of 203 questionnaires collected from shop masters working for women's wear fashion brands were analyzed. Results revealed that VM manual was used most often as a VM supporting activity, and casual brands offered VM training and professional VM help more often than designer brands did. Shop masters' attitude toward necessity, participation and usefulness to VM supporting activities were related to each other as well as to the perceived importance of VM. There were differences in the perceived importance of VM and attitude to VM supporting activities by age and sales career and in the VM management by income. Brand knowledge, the perceived importance of VM, and participation to VM supporting activities affected VM management of shop masters.

Robust, real-time, fully automatic tracking of facial features is required for many computer vision and graphics applications. In this paper, we describe a fully automatic system that tracks eyes and eyebrows in real time. The pupils are tracked using the red eye effect by an infrared sensitive camera equipped with infrared LEDs. Templates are used to parameterize the facial features. For each new frame, the pupil coordinates are used to extract cropped images of eyes and eyebrows. The template parameters are recovered by PCA analysis on these extracted images using a PCA basis, which was constructed during the training phase with some example images. The system runs at 30 fps and requires no manual initialization or calibration. The system is shown to work well on sequences with considerable head motions and occlusions.

Database segmented and labeled up to phoneme level plays an important role in phonetic research and speech engineering. However, it usually requires manual segmentation and labeling, which is time-consuming and may also lead to inconsistent consequences. Automatic segmentation and labeling can be introduced to solve these problems. In this paper, we investigate a method to improve the performance of automatic segmentation and labeling system, where Spectral Variation Function(SVF), modification of silence model, and use of energy variations in postprocessing stage are considered. In this paper, SVF is applied in three ways: (1) addition to feature parameters, (2) postprocessing of phoneme boundaries, (3) restricting the Viterbi path so that the resulting phoneme boundaries may be located in frames around SVF peaks. In the postprocessing stage, positions with greatest energy variation during transitional period between silence and other phonemes were used to modify boundaries. In order to evaluate the performance of the system, we used 452 phonetically balanced word(PBW) database for training phoneme models and phonetically balanced sentence(PBS) database for testing. According to our experiments, 83.1% (6.2% improved) and 95.8% (0.9% improved) of phoneme boundaries were within 20ms and 40ms of the manually segmented boundaries, respectively.
