Nowadays since the customers of HDD's are interested in their noise levels in addition to their primary performances such as their average access time, capacity, HDD manufacturers make efforts on reducing the noise. The works to reduce noise are usually based on the measurable physical quantities such as SPL or acoustic intensity level. However, since the HDD noise is Judged by human beings, the basis of noise reduction should be human sensations. In this paper, the noise levels of various HDD's are evaluated by the human jury test to find a relationship between the physical quantities used for noise control and the human sensations of noise. Discrepancies are found in the judgments by the human beings and by the physical quantities. The loudness level, a psychoacoustic variable, is used to solve the discrepancy.

This paper is to illustrate a variety of court-annexed ADR programs and vindicate its implications of court-annexed ADR in United States. It has been almost three decades since Frank Sender articulated his vision of the multi-door courthouse. The court-annexed ADR originated from the concept of multi-door court house. Professor Sander argued that the court must transform from the court that provides litigation, only one type of dispute resolution, to the multi-door courthouse which provides a variety of dispute resolution methods including a number of ADR programs. The types of court-annexed ADR on which this paper focus are court-annexed mediation, court-annexed arbitration, mini trial, early neutral evaluation(ENE), summary jury trial, rent-a-judge, and med-arb in United States. The findings of this paper is as follows. First, the ADR movement is the irreversible and dominant phenomenon in the US court. The motivation of incorporating ADR into court is to reduce the cost of court to handle the civil disputes and to eliminate the delay of litigation process in the court. At the same time, a couple of studies of ADR revealed that the ADR program satisfied users of ADR. Second, the landscape of ADR has not been fixed. In 1970's, the court-annexed arbitration has been popular. In 1980's, the diverse kinds of ADR programs were introduced into the federal court as well as state courts, such as mini trial, early neutral evaluation(ENE), summary jury trial, and court-annexed mediation. But in 2000s, the court-annexed mediation has been the dominant type of ADR in United States. Third, the each type of ADR program has its own place for the dispute resolution. Since Korean society enters into the stage in which diverse kind of disputes occur in the areas of environment, construction, medicare, etc, it is desirable to take into consideration of the introduction of ADR to dispute resolution in Korea.

The goal of the present paper is to objectify the intrinsic subjectivity of sound as a media of music by applying psycho-acoustical methodology to the analysis of a musical work. First, 18 sound samples are extracted from "Symponie Fantastique" written by Hector Berlioz, which is a piece of program music, and then the objective Zwicher's sound quality parameters such as: Loudness, Sharpness, Roughness and Fluctuation Strength are evaluated for each of these sound samples. For subjective sound quality evaluation, 9 representative sound quality adjectives are extracted on a basis of program feature of Symponie Fantastique and the first jury test is carried out by using the numeric rating method and the paired comparison method. Three sound quality adjectives, "bright", "noisy", and "realistic" are extracted from the factor analysis of the first jury test result. On a basis of the computed sound metrics and the second jury test result for the three sound quality adjectives, three sound quality indexes are developed to represent the sound qualities of "Symponie Fantastique".

In this paper, we tried to find out sound quality metrics to express discomfort of overload excavator noise and to develop sound quality indexes through multiple regression analysis by using them. For this purpose, the interior noise of cabin under overload condition was recorded for six excavator models with different noise properties and Jury test was carried out by PCM (Paired Comparison Method) and MEM (Magnitude Estimation Method). Jury test result with low consistency was classified into two groups with different preference tendencies by cluster analysis and multiple regression analysis was conducted in order to find out which sound quality metrics have significant effects on discomfort(low preference). As a result, we figured out that the sound quality metrics to express the discomfort were the partial loudness (= $PN_{10Bark}$) between 0 and 10 Bark in case of group1 and the difference between engine noise(= $dB_{EG}$) and hydraulic system noise ($dB_1$) in case of group2. Using the results of preference ranking and tendency analysis of PCM followed by the correlation analysis between PCM and MEM, the more reliable results were adopted by excluding the data with low consistency obtained from Jury test via MEM.

Three studies were conducted to examine the degree to which three common heuristics, anchoring heuristic, framing effect and representative-ness heuristic, influence the decision-making precesses of actual judges and 5-persons mock juries. With scenarios regarding various issues that are commonly raised in actual criminal and civil trials, study 1 examined the 158 actual judges' decisions. In study 2, the decisions of 80 mock jury groups that consisted of college students were examined with similar scenarios. And individual decisions were examined in study 3 to compare with the group decisions in study 2. The decision processes of the actual judges and the mock jury groups alike were found to be influenced by "anchors". But the biases by the anchoring heuristic were more pronounced in the group decisions than in the decisions of the actual judges. With respect to framing effect, the actual judges were found to be resistant, while a small effect was found in the decisions of mock jury groups. Representative-ness biases weren't found in the decisions of both the actual judges and mock juries. The implications of the results for judicial systems were discussed.
