The purpose of this paper is to explain the horizontal structure of Prelude, Op. 74, No. 4 by Skryabin objectively and logically by utilizing transformational networks to analyze the voice leading of this music. David Lewin explained transformational relations in musical space through a visual graph called a network and introduced a frame of analysis which simplified complicated aspects of music. There were other methods that analyse horizontal voice leading in atonal music by means of Lewin's transformational theory. Of these methods, Henry Klumpenhouwer's ‘transformational networks’ and Shougn J. O'Donnell's ‘dual transformation’ have been adopted as a primary analytical method for this article. The network of Prelude, Op. 74, No. 4 by Skryabin is composed of eleven types of set classes, made up of transposition transformation. The network has verified the similarity between pitch classes by utilizing isography, which shows its pitch-class contents. In this article, I hope to show that atonal music composition has a delicate structure.

This purposes of this study were to explain consumer attitudes and purchasing behaviors towards agricultural products using a social network service and to determine the influencing factors such as experience, technology ability, innovation, self-efficacy, perception of usefulness, perception of trust, attitude, purpose of purchase and individual characteristics on them. We analyzed the survey data set, using the ‘logit model’, ‘simultaneous equation model’, and ‘LISREL-Type model’ In this study, the results obtained are summarized as follows. The result for the comprehensive statement of “Trust” was the biggest influence on the purchase agricultural products using the social network service. Therefore, in order to expand agricultural e-commerce using SNS, trust should be to the fore of marketing and publicity campaigns, in order to promote and stabilize the market.

PURPOSES : The purpose of this study is to check the possibilities of traffic pattern analysis using MatSIM for urban road network operation in incident case. METHODS : One of the stochastic dynamic models is MatSIM. MatSIM is a transportation simulation tool based on stochastic dynamic model and activity based model. It is an open source software developed by IVT, ETH zurich, Switzerland. In MatSIM, various scenario comparison analyses are possible and analyses results are expressed using the visualizer which shows individual vehicle movements and traffic patterns. In this study, trip distribution in 24-hour, traffic volume, and travel speed using MatSIM are similar to those of measured values. Therefore, results of MatSIM are reasonable comparing with measured values. Traffic patterns are changed according to incident from change of individual behavior. RESULTS : The simulation results and the actual measured values are similar. The simulation results show reasonable ranges which can be used for traffic pattern analysis. CONCLUSIONS : The change of traffic pattern including trip distribution, traffic volumes and speeds according to various incident scenarios can be used for traffic control policy decision to provide effective operation of urban road network.

 ,  , Understanding the ecological complexity and habitat of a species are crucially important to conserve an endangered species. This study evaluated the patch network ecology of the endangered species Parnassius bremeri. The results indicated that 188 individuals were captured and 220 were recaptured, respectively. The sex ratio of female: male was 42:146, males were four times more abundant than females. The average longevity of an adult was 3.93 ± 3.93 days (male, 4.0 ± 3.9, female, 2.5 ± 1.0 days), the maximum longevity was 14 days for males and 13 days for females, respectively. Therefore, the expected longevity of males was longer than that of females. The average emigration distance for the species was 377 m, and the maximum emigration distance was 1550 m. The analysis of patch connectivity and individual colonization revealed that the ideal distance between patches was about 300 m. Moreover, a >, 600 m patch distance decreased the colonization rate severely. We also observed higher immigration and emigration between patches that were clustered in close proximity. This leads us to conclude that a higher number of patches at a close distance is best suited for P.bremeri. We find these results to be crucial to determine a policy to protect and conserve this endangered species.
