  • Spectral modeling synthesis (SMS) has been used as a powerful tool for musical sound modeling. This technique considers a sound as a combination of a deterministic plus a stochastic component. The deterministic component is represented by the series of sinusoids that are described by amplitude, frequency, and phase functions and the stochastic component is represented by a series of magnitude spectrum envelopes that functions as a time varying filter excited by white noise. These representations make it possible for a synthesized sound to attain all the perceptual characteristics of the original sound. However, sometimes considerable phase variations occur in the deterministic component by using the conventional SMS for the complex sound such as whale sounds when the partial frequencies in successive frames differ. This is because it utilizes the calculated phase to synthesize deterministic component of the sound. As a result, it does not provide a good spectrum matching between original and synthesized spectrum in higher frequency region. To overcome this problem, we propose a modified SMS that provides good spectrum matching of original and synthesized sound by calculating complex residual spectrum in frequency domain and utilizing original phase information to synthesize the deterministic component of the sound. Analysis and simulation results for synthesizing whale sounds suggest that the proposed method is comparable to the conventional SMS in both time and frequency domain. However, the proposed method outperforms the SMS in better spectrum matching.

  • This paper presents an application of the Ecological Interface Design (EID) theoretical framework for developing an optimal display of railway safety monitoring system (SMS) in stations. Especially, Work Domain Analysis (WDA) which is the preceding research for EID was conducted. This study proceeds as follows: First, urban railway SMS in stations was defined as a system boundary for WDA, and work environment for station personnels was analysed through Abstraction Hierarchy (AH). AH represents five levels (Functional Purpose, Values and Priority Measures, Purpose-related Functions, Object-related Process, Physical Object) of informations that station personnels obtain from work environment, and Work Domain Model (WDM) was derived as a result of the AH. To confirm how well WDM represents the real work environment of SMS, Scenario Mapping was conducted with experts who has been working as a station personnel for more than ten years. Lastly, thirteen additional information requirements that are not provided by the existing SMS as well as all the information that are provided by the existing SMS were extracted using confirmed WDM. These information requirements can be used as essential information for EID of urban railway SMS.

  • More precise estimation of the bed change, primary cause of flood damage, has been recognized significant for designs of levees and other river facilities. In this study, the long-term bed change was examined as the application of the relatively new Surface-water Modeling System (SMS) Model because there has not been broad verification of the model empirically on river of South Korea. This 2-dimensional model was used to examine the bed change of Pochon Stream Basin, a tributary of Imjin River, where heavy rain damages annually occur. First, in order to verify the model, the simulating period was set from 1986 to 1998 because of the existence of the field measurements. Cross sectional field measurements of 1986 were used for the initial condition and output were compared and analyzed with the observed cross sectional data in 1998. As the results of the verification, the comparison in lateral and streamwise bed level between results from the model and the field measurements showed a reasonable agreement except for the some cases of local scours. However, in terms of the quantitative comparison, the change of the bed elevations for each cross section for 1998 was rather underestimated than that of the field measurements.

  • This study investigated changes in quality characteristics of wrap- and vacuum-packaged peeled lotus roots treated with strong acidic electrolyzed acid water (SAEW pH 2.58, ORP 1,128 mV, HClO 105.0 ppm) or low alkaline electrolyzed water (LAEW pH 8.56, ORP 660 mV, HClO 73.8 ppm) as immersion liquids prior to packaging and storage at 5C. Immersion of peeled lotus roots in SAEW and LAEW reduced initial microbial load by about 1 log compared to treatment with tap water (TW). Hardness differences on storage were observed. However, reduction in PPO activity by electrolyzed water was not reproducible. Changes in Hunter's color value and the color difference value ($\Delta$) of peeled lotus roots immersed in 0.5% (w/v) sodium metabisulfite (SMS) and electrolyzed water were smaller than those of roots treated with TW prior to storage. Sensory characteristics measured during storage were best-preserved in lotus roots previously immersed in 0.5% (w/v) SMS or electrolyzed water, compared to TW. Immersionin electrolyzed water and vacuum packaging preserves the quality of peeled lotus roots in terms of microbial, visual, and sensory aspects, at levels comparable to those offered by storage after treatment with 0.5% (w/v) SMS.

  • 세계적으로 유명한 자동차 생산회사인 르노사와 장갑판재 분야에서 세계적 선두기업인 Creusot-Loire Industrie사 연합으로 설립된 것이 SMS사이다. SMS사의 특징중의 하나는 수요자의 요구조건을 만족시키는데 있어, 다른 경쟁사에 비해 매우 높은 유연성을 가졌다는 점에 있다. 이를 가능케 하는 것은 생산품목의 다양성 때문이다. 그러므로 SMS는 다양한 품목을 제공하여 전세계에 걸쳐 있는 수요자의 요구를 충족시킬수 있다. 지금까지 SMS는 프랑스 육군에 3천2백대, 동남아시아, 아프리카, 중동, 유럽 및 남미지역등 약 12개국의 육군에 1천2백대를 인도하였다.
