The purpose of this study is to analyse the main factors and attributes of psychological evaluation to noise. For this purpose, a psycho-acustic experiment was conducted by using the method of rating scale. 52 subjects were participated in the experiment, 20 stimuli were presented to subjects in random order with 23 adjectives. As a result of factor analysis, it was found that the primary factors for evaluating the quality of noise subjectively are four factors of unpleasantness, intensity, irregularity, and sharpness. And, as a result of MDPREF(multi-dimensional analysis of preference data), it was found that the noise sources including the factors of unpleasantness, intensity, and irregularity are related to the sounds of hammering in construction field, car horn, road traffic, idling of car, and printing by computer printer, and the factor of sharpness are the sounds of car siren, claps of thunder, car horn, and snowstorm etc.

본 논문은 명대 소설 『봉신연의(封神演義)』의 문중(聞仲) 서사와 대순진리회 경전 『전경』의 강증산(姜甑山) 서사를 비교 고찰함으로써, 구천응원뇌성보화천존 신격을 서사적 상상력의 차원에서 논의하고자 하였다. 논의는 다음의 세 가지 차원에서 진행되었다. 첫째, 『봉신연의』 문중서사에 고조선 신화의 뇌신(雷神) 이미지와 한국 선도 전통의 문화적 맥락이 반영되어 있고, 그러한 문화적 맥락이 다시 『전경』 강증산 서사에서도 곳곳에 나타나 있음을 살펴보았다. 둘째, 『봉신연의』 문중 서사에 표현된 '봉신(封神)'이라는 개념의 본질을 『전경』 강증산 서사에 나타나는 '해원(解冤)' 사상과 관련지어 고찰하였다. 셋째, 『봉신연의』에서 문중이 속해 있는 '절교(截敎)'라는 집단이 가지는 이류(異類) 포용의 특성을 『전경』에서 강증산이 추구하는 '상생(相生)'의 가치와 관련지어 논의하였다. 본 논문에서 도출한 구천응원뇌성보화천존 신격의 서사적 상상력에는 은(殷)을 포함한 동이계 종족의 설화와 문화에 대한 '망탈리테(mentalité)'가 반영되어 있었다. 이는 해당 신격이 태생적으로 한국 고유의 선도(仙道) 전통 및 한국 도교와 깊은 관련이 있음을 의미한다.

Shear modulus is directly linked to material's stiffness and is one of the most critical engineering parameters. Seismically, shear-wave velocity (Vs) is its best indicator. Although methods like refraction, down-hole, and cross-hole shear-wave surveys can be used, they are generally known to be tougher than any other seismic methods in field operation, data analysis, and overall cost. On the other hand, surface waves, commonly known as ground roll, are always generated in all seismic surveys with the strongest energy, and their propagation velocities are mainly determined by Vs of the medium. Furthermore, sampling depth of a particular frequency component of surface waves is in direct proportion to its wavelength and this property makes the surface wave velocity frequency dependent, i.e., dispersive. The multichannel analysis of surface waves (MASW) method tries to utilize this dispersion property of surface waves for the purpose of Vs profiling in 1-D (depth) or 2-D (depth and surface location) format. The active MASW method generates surface waves actively by using an impact source like sledgehammer, whereas the passive method utilizes those generated passively by cultural (e.g., traffic) or natural (e.g., thunder and tidal motion) activities. Investigation depth is usually shallower than 30 m with the active method, whereas it can reach a few hundred meters with the passive method. Overall procedures with both methods are briefly described.

Network Coding (NC) is a new paradigm for network communication. In network coding, intermediate nodes create new packets by algebraically combining ingress packets and send it to its neighbor node by broadcast manner. NC has rapidly emerged as a major research area in information theory due to its wide applicability to communication through real networks. Network coding is expected to improve throughput and channel efficiency in the wireless multi-hop network. Many researches have been carried out to employ network coding to wireless ad-hoc network. In this paper, we proposed a dynamic queue management to improve coding opportunistic to enhance efficiency of NC. In our design, intermediate nodes are buffering incoming packets to encode queue. We expect that the proposed algorithm shall improve encoding rate of network coded packet and also reduce end to end latency. From the simulation, the proposed algorithm achieved better performance in terms of coding gain and packet delivery rate than static queue management scheme.

The culture interest regarding the new area causes an effect even in change of fashion and that result Mongol area where it is area other than Japan, China and India and it is having compromised beauty raised it's head. Mongol is in Noin-ula area which is a it's former self of the Hun's. There is to a textile pattern which was used not only the textile pattern which has the feature of Scythian system but also the textile pattern which has the feature of China was used. The feature of Noin-ula's the textile pattern is as follows. Noin-ula's textiles used Scythian system of animal pattern, vine pattern, palmette pattern, thunder pattern, spiral pattern, shape of diamond pattern. Scythian system of animal pattern and vine pattern proves the interchange with the countries to the west of China. Noin-ula's textile pattern is applied to the designer's work of art. The designers are John Galliano, Etro, Chloe, Emmanuel Ungaro and so on, who express the modern ethnic style design. Because the more developed the modern society is the more embossed feature of intention for the race and the fork art, I think that Ethnic style design is applied to modern sensitive and ethnic style in the future.

Objectives: The purpose of this paper is to describe the role for public education in mental health promotion, prevention of mental illness and treatment of mental disorders in Canada. Results: A brief history of the changing nature of the way we treat mental disorders in Canada argues for an increasingly critical role for public education. Furthermore, the new understanding of the role of social determinants in prevention of mental illness again necessitates a vital role for public education as the shift in focus moves from exclusively individual-focused health care treatments to creating supportive environments. The roles for mental health public education then become: advocacy for the social determinants of health approach, better understanding of the nature of mental health problems, useful information for self-management, and more knowledge about appropriate treatments. A brief discussion of the structure of the response in Canada provides an overview of national and provincial responsibilities in mental health care with a case study highlighting one community's response to addressing mental disorders. Conclusion : Finally, challenges regarding the most effective educators and the issue of professional expertise embedded in the status quo are discussed.
