Long-term care insurance is a social insurance system that provides benefits to the elderly who have difficulty taking care of themselves for a period of at least 6 months. This system was started in July, 2008 and it is very important to set proper judgement ratings for the approval process. We try to develop and improve the judgement rating system using decision tree models. Our tree model is found to be more stable and efficient than the previous one.

A major problem of stopwatch time study is how to do for the accurate and consistent performance rating, which is one of the critical variables to determine the accuracy of work measurement and should be still dependent upon time observer's judgement. Therefore the time observer's ability for the performance rating is very important, and must be improved by correct training method and procedure. This paper developed a new benchmark and benchmark-observation method for the effective performance rating training of assembling and machining operations. The trainees' ability in the accuracy and consistency of the performance rating ,improved significantly after being trained by subject method. The percentage improvement in rating accuracy and consistency values was 34.7% and 49% respectively. In addition, benchmark-practice method for the performance rating training is not significant, so it is proofed that the skill of a certain operation is not important for the improvement of the rating ability.

Bridge load rating calculations provide a basis for determining the safe load capacity of bridge. Load rating requires engineering judgement in determining a rating value that is applicable to maintaining the safe use of the bridge and arriving at posting and permit decisions. Load testing is an effective means in calculating the rating value of bridge. In Korea, load carrying capacity of bridge is modified by response modification factor that is determined from comparisons of measured values and analysis results. The response modification factor may be corrupted by vehicle location error that is defined as the gap of test vehicle location between load testing and analysis. In this study, the effects of vehicle location error to structural response and response modification factor are investigated, and a new method for evaluating response modification factor is proposed. The random data analysis shows that the proposed method is less sensitive to vehicle location error than the present method.

Different aspects of morality, namely, moral belief, moral judgement and moral behavior have been studied seperately. This study examined the development of these three aspects of morality in relation to internal attribution in one sample. A total of 371, third -and sixth- grade children from Masan city were responded to questionnaires on moral belief, moral judgement, and attibutional tendency. In addition, children's moral behavior was measured by the teachers' 5-item rating scale. As results, there were signigicant but low correlations among three components of morality. There were developmental differences in moral belief and moral judgement but there was no age difference in moral behavior. Compared to third graders, sixth graders were higher in moral judgement but lower in moral belief. Social experience as well as cognitive development on moral relativity could explain this paradoxical developmental trend in moral belief. There was a sex difference only on moral behavior : Girls were rated higher in moral behavior than boys. Internal attribution was significantly correlated with all three aspects of morality, .15 with moral belief, .45 with moral judgement, .14 with moral behavior, respectively. There was a significant developmental difference but no sex difference in attributional tendency: Sixth graders reported higher internal attribution than third graders. However, there was no developmental difference in correlations among internal attribution and three aspects of morality. Most importantly, internal attribution explained morality better than either age -or sex- variable. It was suggested that educational programs on morality need to focus on the internalization of it.

Bridge load rating calculations provide a basis for determining the safe load capacity of bridge. Load rating requires engineering judgement in determining a rating value that is applicable to maintaining the safe use of the bridge and arriving at posting and permit decisions. Load testing is an effective means in calculating the rating value of bridge. In Korea, load carrying capacity of bridge is modified by stress modification factor that is determined from comparisons of measured values and analysis results The stress modification factor may be corrupted by vehicle location error that is defined as the gap of test vehicle location between load testing and analysis. In this study, the effects of vehicle location error to structural response and stress modification factor are investigated, and a new method for evaluating stress modification factor is proposed. The random data analysis shows that the proposed method is less sensitive to vehicle location error than the present method.

Objective : The present study investigated the interpretation bias and expectation and judgemental bias of performance in socially anxious children. Method : Children with high social anxiety (n=18) and low social anxiety (n=16) were recruited through self-report and peer nomination, Participants performed three tasks to assess for cognitive bias. The first task measured interpretation of ambiguous social situations. The second task measured expectations regarding performance in a three minute impromptu speech. The third task assessed for judgemental bias via comparison between post-speech self rating and observer rating. Result : Children with high social anxiety did not differ significantly from low social anxiety children on the dependent measures assessing bias in interpretation, expectation and judgement. However, a significant difference was found in the judges' rating of children's performances on the speech task, with high social anxiety children obtaining significantly lower scores compared to low social anxiety children. Conclusion : The role of cognitive biases in the development and maintenance of social anxiety in children was discussed.

The purpose of the present study was to evaluate the effect of 7-point interval scale(EAI) and visual analogue scale(VAS) on perceptual judgement and the reliability of severity on voice problems by dysphonic speakers. 30 undergraduate students studying communication disorder were enrolled in the perceptual evaluation. Those listeners judged overall voice severity within the anchored(condition 1) and non-anchored scales(condition 2) for vowel prolongation and reading tasks by 25 speakers with voice disorder. The results of this study showed that the scores by VAS was significantly higher than EAI in both condition 1 and condition 2 for vowel prolongation and reading task. However, the scores by EAI method was higher than by VAS method on voice severity of vowel prolongation (condition 1) and reading task(condition 2). These results suggest auditory-perceptual scaling procedures must be more studied in the aspects of clinical application of voice disorder.

Bridge load rating calculations provide a basis for determining the load carrying capacity of bridges. Load rating requires engineering judgement in determining a rating value that is applicable to maintaining the safe use of the bridge and arriving at posting and permit decisions. Load testing is an effective means in calculating the rating value of bridge. In Korea, load carrying capacity of bridge is modified by response modification factor that is determined from comparisons of measured values and analysis results. This paper presents the development of a method for determining the response the modification factor, using traffic loads. The proposed method is based on the results of computer simulations of traffic action effects. The simulation program generates random traffic actions for defined traffic conditions and determines the frequency distribution of maximum traffic action effects. A comparison between the proposed method and the present method shows good agreement in estimating the modified load carrying capacity of bridges.

Perceptual judgement method is frequently used in evaluating dysarthric speech. Although most of speech pathologists and researchers focus on the 38 perceptual features provided by Darley, Aronson & Brown(1969) during evaluation, there are additional characteristics that may be useful to describe dysarthria in literature. We reviewed previous dysarthria literature and selected 46 perceptual characteristics that could be examined at various subsystems of speech production. We also provided explanations and rationale for the rating method for each of the perceptual characteristics. This attempt might aid to offer a basic ground for developing a diagnostic tool of dysarthria.

The ratings of noise are consisted of physical factors and psychological factors. The physical factor means the scales and the spectrum characteristics of noise, on the other hand the psychological factor means the subjective emotion, sensation and individual judgement for it. Therefore the rating of noise must reflect the subjective psychology of people for it. But it is very difficult to establish an effective scale which can reflect well that because the subjective psychology has many variables according to the cultural differency, nationality and individual personalities. In this paper, Korean Vocabularys for the assessment of noise were surveyed in order to find out the effective noise scale for Korean.
