Feature extraction of CASA system uses time continuity and channel similarity and makes correlogram of auditory elements for the use. In case of using feature extraction with cross correlation coefficient for channel similarity, it has much computational complexity in order to display correlation quantitatively. Therefore, this paper suggests feature extraction method using non-parametric correlation coefficient in order to reduce computational complexity when extracting the feature and tests to segregate target speech by CASA system. As a result of measuring SNR (Signal to Noise Ratio) for the performance evaluation of target speech segregation, the proposed method shows a slight improvement of 0.14 dB on average over the conventional method.

The Gallery of Casa del Agua in Jeju Island was demolished by Jeju local government on March 6 in the last year. In the meanwhile, a lot of people including the architectural field had denied the demolition. Regardless of sustained efforts in order that the building could be preserved as a work, Jeju government ended up with demolishing the gallery. The Gallery of Casa del Agua was a temporary building constructed as a model house of Casa del Agua. As the remaining period of the temporary building had passed, it was on the verge of demolition by Jeju government. Casa del Agua is 'dwelling of water' in Korean, and the building was the last posthumous work of Mexican architect Ricardo Legorreta. Knowing from the expression of 'dwelling of water', this house is a dwelling work of him. Through this work, his architecture languages that he had pursued contained in dwelling could be looked into. This study examined the background and course of demolition of the Gallery of Casa del Agua, 'dwelling of water' and arranged problems in the course of demolition. Then, the fact that the Gallery of Casa del Agua as an architecture work of Ricardo Legorreta included his architecture languageswas analyzed. For this, his universalarchitecture languages were examined and how the architecture languages were applied to the Gallery of Casa del Agua was analyzed. As a result, it could be known that languages of composition and languages of emotion consistently shown in his works were represented in the Gallery of Casa del Agua.

When there are background noises or some people speaking at the same time, a human's auditory sense has the ability to listen the target speech signal with a specific purpose through Auditory Scene Analysis. The CASA system with human's auditory faculty system is able to segregate the speech. However, the performance of CASA system is reduced when the CASA system fails to determine the correct position of the speech. In order to correct the error in locating the speech on the CASA system, voice activity detection algorithm is proposed in this paper, which is a combined auditory scene analysis with PAR(Periodic to Aperiodic component Ratio). The experiments have been conducted to evaluate the performance of voice activity detection in environments of white noise and car noise with the change of SNR 15~0dB. In this paper, by comparing the existing algorithms (Pitch and Guoning Hu) with the proposed algorithm, the accuracy of the voice activity detection performance has been improved as the following: improvement of maximum 4% at SNR 15dB and maximum 34% at SNR 0dB for white noise and car noise, respectively.

Giuseppe Terragni was one of the founding member and a leading Italian Rationalist pursued a new and more rational synthesis between the nationalistic values of Italian Classicism and structural logic of the machine age. Casa Giuliani Frigerio, a four-story apartment housing in Como, is one of his last major work and is worth to investigate the composition of facades in terms of ambiguity. Unlike the Casa del Fascio, it is never possible to read an priori whole and to allow static and unified readings in a traditional alignment. Due to its misalignments found within the facades of Casa Giuliani Frigerio, it is evident to present unstable and disjunctive readings. These distinctive facades are read as layers applied onto some equally unstable underlying layer and form an ensemble of unexpected unity.

Stem firmness and flowering response of cut lily as influenced by medium composition (Control; Upland soil, Pt; Peatmoss, Pe; Perilite, Ve; Vermiculite, Rrh; Rotted rice-hull, RPt: Russian Peatmoss) were studied. For 'Casa Blanca', plant height and length of flower stalk increased when bulbs were planted in Pt:Rrh:Ve (1:1:1, v.v$^{-1}$ ), and dried leaves of lower part plants decreased in RPt:Pe:Rrh (1:1:1, v.v$^{-1}$ ). In case of 'Marco Polo', plant height and length of lower stalk increased in Pt:Rrh (1:1, v.v$^{-1}$ ) as compared to other treatment, number of leaves and dried leaves increased when bulbs were planted in RPt:Pe:Rrh (1:1:1, v.v$^{-1}$ ) as compared to the control. Flowering of 'Casa Blanca' increased in RPt:Pe:Rrh (1:1:1, v.v$^{-1}$ ) as compared to the control and that o 'Marco Polo' increased when bulbs planted in Pt:Rrh(1:1, v.v$^{-1}$ ). Flower-bud blasting of both cultivars increased with Pt as compared. Stem firmness of 'Casa Blanca' increased in Pt:Pe:Ve (1:1:1, v.v$^{-1}$ ), and especially stem firmness of upper part plant of 'Marco Polo' increased in Pt:Rrh (1:1, v.v$^{-1}$ ) as compared to the control. Generally, stem firmness of 'Casa Blanca' was not influenced by the culture medium.

Our society has an obligation and responsibility to respect and protect the character of the child. Recently, however, Korean society has been suffering from child abuse and abuse that is pouring out every day. In order to protect these children, the child protection system and the judicial system should be fundamentally child-friendly. The CASA(Court Appointed Special Advocates) volunteer program, which is being held in the United States with such a concern, is a continuing program of court attendance and emotional support services for abused children throughout the United States. In Korea, however, there are many similar programs such as mentoring projects, dream co-supporters project similar to the CASA program in various organizations of the region and the enactment of the Act on the Punishment of Child Abuse increases the involvement of the public system in child abuse. There is also an increased awareness of children's rights and strengthened government intervention through active monitoring to prevent recurrence of child abuse. These changes in the Korean society should be actively reviewed by the US CASA program and settled as a national project in the Korean society so that the system of protecting the safety and rights of the victims of child abuse will be established. It is anticipated to be a way to prevent social problems from occurring in advance.

Conventional context-aware service models permit the access of resources only by user authentication, but the ubiquitous environments where the context information around users is changing frequently require the resource access control according to the rapid changes. This paper proposes a scheme to control access permission of resource dynamically as context information of user changes. Our access control model is based on traditional CASA (Context-Aware Security Architecture), but can restrict the access of the user already has been authorized. With the real-time checking of context information, our scheme gives different access controls according to changes in environmental information, and provides more secure services than conventional context-aware models.

This experiment was conducted to find out suitable extraction time of available fragrant component in Lilium Oriental Hybrida 'Casa Blanca' based on qualitative and quantitative variation of its fragrant component in its flowering stages. The content of essential oil in its flowering stages increased with the progress of flowering stages except flower bud stage and it had the most oil content in its stage after full bloom. The analysis of the essential oil in Lilium Oriental Hybrida 'Casa Blanca' in its flowering stages shows that its main constituents were farnesol (18.96%), benzyl salicylate (13.81%), butyl-hydroxy toluene (12.87%), geranyl linalool isomer (7.46%), isoeugenol (7.17%) in its each stage. Benzenoids had much content at half bloom stage and full bloom stage while fatty acid derivatives had much content at initial flowering stage and after flowering stage. Most benzenoids such as butyl-hydroxy toluene and isoeugenol, which are some of main constituents of Lilium Oriental Hybrida 'Casa Blanca' had strong antioxidant effect. So they were expected to be used as antioxidant agents for food, feed, vegetable oil. The content of monoterpene compounds like geranyl linalool isomer increased at its later stage. Sesquiterpene such as farnesol, which is main component of lily existed only at full bloom stage. Therefore farnesol and geranyl linalool isomer of Lilium Oriental Hybrida 'Casa Blanca' are expected to be used for important spices with good fragrance. The suitable extraction time for the usable main constituents of Lilium Oriental Hybrida 'Casa Blanca' is as follows; farnesol and benzyl salicylate: at full bloom stage, butyl-hydroxy toluene: at half bloom stage, geranyl linalool isomer and isoeugenol: at stage after full bloom. Finally there was variation in essential oil components and contents of Lilium Oriental Hybrida 'Casa Blanca' in its flowering stages and they are expected to be used usefully for flavor industry, food industry, aromatherapy, when they are extracted at their suitable extraction time.

We propose a new method to apply shape analysis techniques to a computational auditory scene analysis (CASA)-based speech separation system. The conventional CASA-based speech separation system extracts speech signals from a mixture of speech and noise signals. In the proposed method, we complement the missing speech signals by applying the shape analysis techniques such as labelling and distance function. In the speech separation experiment, the proposed method improves signal-to-noise ratio by 6.6 dB. When the proposed method is used as a front-end of speech recognizers, it improves recognition accuracy by 22% for the speech-shaped stationary noise condition and 7.2% for the two-talker noise condition at the target-to-masker ratio than or equal to -3 dB.
