In this study, the possibility of decision error is investigated to identify and improve the reliability of participants in the process of conducting the sound quality analysis for laser printers. So far, there is not a way to identify and express the possibility of individual participant quantitatively. Thus, the decision error model is proposed which is based on the expectation value between the perceived sounds. Through the experimental verification on the laser printers, it was found that the possibility of decision error is affected according to the normalized difference. The possibility of decision error has inversely proportional to the normalized difference between the perceived sounds. When the normalized difference becomes small value, the uncertainly between decisions is inversely increase, and then it is difficult to obtain the proper result in the process of the jury evaluation for laser printers. For this reason, in this study, the proposed decision error model is added in the previous step of the correlation verification. Comparing to the conventional process only using the correlation based method, after the reliability of each participant is verified, the correlation with the mean response of participants is verified. It was found that the participants who were recognized as having unusual preferences are actually identified as having the reliability problem. Based on the results of this study, the proposed decision error model will be helpful to identify and improve the reliability of participants in the following study for the sound quality analysis.

Household refrigerator radiates noise of which the pattern is dependent on the operating condition of its parts, such as compressor, flow fans, etc. Thus the refrigerator noise has a variety of frequency characteristics. Therefore, it is required to consider the noise characteristics for evaluating the noise quality and eventually developing the sound quality index of the refrigerator noise. In this study, five units of household refrigerator were selected to measure their noises that were used to generate sound sources for jury test of the study. The measured noises of five refrigerators were divided into ten kinds of sound source by considering operating condition and frequency characteristics. Additionally, the ten sources were each edited to have the same SPL of 30 dBA. Totally twenty kinds of sound sources (10-original SPL, 10-edited SPL 30 dBA) were evaluated by twenty-two subjects, and compared with their sound quality metrics. It was found that only the loudness of the metrics was meaningfully correlated with the subjective evaluation. The rests, sharpness, roughness and fluctuation strength, were not related. The conclusion of this study is that a new sophisticated index is necessary to be developed to qualitatively evaluate the household refrigerator noise.

오늘날 기업에게 기술력과 디자인은 무한경쟁시대에서 요구되는 전제조건으로 인식되고 있다. 대부분의 기업 특히 도자기기업에서는 실용적이거나 또는 제품의 미적인 부분을 개별적으로 다루고 있는 것이 사실이다. 이에 따라 기업의 아이덴티티를 형성하기에 어려움을 겪게 된다. 그러나 독일의 로젠탈사의 경우 이미 1900년대 중반부터 디자인과 더불어 독창적인 프로세스를 통하여 기업의 아이덴티티를 확립하였으며, 독창적인 디자인 매니지먼트를 통해 제품을 생산하는 기업으로 평가되고 있다. 특히 로젠탈의 아이덴티티는 디자인 결과물이 아니라 개발 프로세스를 검증하는 "Jury System"과 독립브랜드 마케팅 그리고 순수 예술가들과의 콜라보내이션과 같은 실험정신에 의해 더욱 독창적으로 형성되고 있다. 특히 디자인 개발에 예술가들이 참여함으로써 이 기업의 도자기 제품은 단순히 생활도자 제품만이 아니라 감상과 수집을 위한 명품으로 평가되고 있다. 또한 로젠탈은 기업 아이덴티티가 단순히 제품에 의해 생성되는 것이 아니라, 디자인 경영기술을 통한 기업 내 외적 요인에 의해 완성될 수 있음을 보여주고 있다.

The sound quality based on design optimization, throughout the development process of various electronic office equipments, needs to be considered in order to respond the increased needs for the emotional satisfaction of customers in terms of psycho-acoustics. This paper focuses on how to describe the characteristics of operating sound radiated from laser printers by using various sound attributes, and to model the sound quality index that can properly evaluate the subjective preference on modification conditions in the improvement study quantitatively. Especially, the proposed verification process, in the form of combining the correlation based method and the decision error based method, was applied to improve the generality and reliability of a group of participants in the jury evaluation. The modified Aures tonality model was also proposed to improve the correlation coefficient with the mean response of participants by optimizing some parameters. As a result, the loudness, articulation index, roughness, tonality, fluctuation strength were used to model the sound quality index for laser printers by using the multiple-linear regression method. Through the improvement study, it was confirmed that replacing the absorbing materials is effective to reduce the tonalness radiated from the side of a reference printer model. Based on above results, it can be concluded that the proposed model has enough usefulness as quantitative evaluation index to evaluate the difference between modification conditions in the improvement study.

우리나라 형법 제10조 제1항에서는 "심신장애로 인하여 사물을 변별할 능력이 없거나 의사를 결정할 능력이 없는 자의 행위는 벌하지 아니한다"라고 규정하고 있다. 따라서 정신장애자가 행위 시에 책임능력이 결여되었다고 판정되면 형사처벌을 할 수 없다. 정신장애자에 대한 책임능력의 판단 문제는 형법학과 정신의학이 교차하는 영역에 존재한다. 정신장애로 인한 책임능력의 존부에 대해서는 최종적으로 법원이 판단하게 되지만 생물학적 요소인 정신장애에 대한 판단은 정신의학적 지식이 필요하고 이에 의존하는 것이 당연하다. 특히 국민참여재판의 시행으로 정신장애자의 정신감정 절차와 내용에서 변화가 요구된다. 일반시민들로 구성된 배심원이 재판의 심리에 참가하게 되므로 배심원이 정신감정의 결과를 이해하고 판단할 수 있도록 더욱 정확한 정신감정과 결과를 제출하는 절차의 개선이 필요하다. 형사사법절차에서 정확한 정신감정결과를 담보하기 위해서는 형사사법과 사법정신의학에 관한 일정한 교육프로그램을 이수한 정신과 의사 또는 심리학자로 구성되는 인력-풀을 구축하고, 인력-풀에 소속된 감정인을 선정하여 정신감정을 실시하는 것이 바람직하다. 나아가 국민참여재판에서 일반시민으로 구성되는 배심원의 비전문성을 고려해야 하므로 알기 쉬운 정신감정서의 작성과 제출이 요구된다. 정신장애 여부에 관한 배심원의 공정한 평결을 위해서는 정신감정서의 신속한 제출과 중요한 내용을 요약한 정신감성서의 제출, 배심원이 쉽게 이해할 수 있는 정신감정서의 작성이 필요하다.

This paper investigates on the legal doctrine of "voluntary, knowing, and intelligent" (VKI Doctrine). The main points that were discussed include the history of the VKI doctrine and the US courts' attitudes toward the doctrine. It was also discussed how the VKI doctrine influenced the protection of consumer who agreed to arbitrate with businesses. The US courts' attitudes have shown to be split in application of the VKI doctrine to disputes in the enforceability of arbitration agreement between the consumers and the businesses. In order for the arbitration agreement to be invalidated, the state legislature cannot enact law that are directly targeted toward the validity of arbitration agreement. Rather the contract law in each of the state should be applied to the evaluation of the validity of an arbitration agreement. As the more and more consumers become familiar with the arbitration, the need for the VKI doctrine to protect the individual consumers in arbitration is expected to be diminished in future disputes.

Generally, noise from a indoor air conditioner has been measured by overall sound pressure level, dB. Customers evaluation, however, of the noise from an air conditioners should not be depend on the only overall level but also the sensory feeling. Moreover, in this sensory evaluation, irregular, time-varying and uneven sounds which are difficult to describe itself by overall level are more affectable. Unfortunately however the formal evaluation method for this kinds of noise is not determined yet. In this research, the evaluation method for tonal noise, which is one of the unmeasurable sounds by overall level, is proposed to evaluate its acceptability based on the consumer's sense of hearing. To consider the consumer's sense, several times of Jury evaluation are carried out. The proposed approach could be applied to the other sound, which acoustical characteristics are similar to the tonal noise .

In this study, the sensitivity of annoyance was investigated by the subjective jury test for the variations of the frequency components along with various sound pressure levels of sixteen environmental noise sources. Annoyance was, also, evaluated for the road traffic noises. Sound pressure levels were $54{\sim}84\;dB$ which individually divided frequency components with eight bands of equally three bark bands. The results show that vehicle traffic noise is recognized as the most serious environment noise source. The sensitivity of human perception of annoyance in frequency bands is quite different from A-weighting curve. The annoyance found out to be more sensitive in high frequency region and reached its maximum in 3.4 kHz.

There are various sounds in the car as much as cars have many mechanical parts. These sounds make various psychological development. The international competition in car markets has continuously required the research about the sound quality of a car. The domestic car makers have also invested a lot of money for the research and development of sound quality. Car axle plays an important role in a vehicle and its NVH development is also important. By this time, NVH development of car axle is mainly based on the reduction of sound pressure level (dBA), which cannot gives, the satisfaction to the customers in view of the sound quality of a vehicle. Therefore, in this paper, a sound quality index evaluating the sound quality of axle noise based on human sensibility is developed.
