Korean Classical Music, as the abbreviated wording for 'Korean Music', is being used as the indicating phraseology for our traditional music that distinguishing from Western Music, the foreign music or foreign-styled popular music. Since such Korean Classical Music has the different acoustic characteristics from Western Music, it needs its own performance space for the special exclusive-use of Korean Classical Music. Likewise, even though the demand for the performance space of special exclusive-use for Korean Classical Music where Korean Classical Music is rendering, is on increasing tendency due to the increase of national concern about traditional culture art, since it is being planned without any concrete standard or method that gratifies the supreme listening condition, it is the real situation that a securement of the satisfying acoustic condition is very difficult, after the completion of construction. On such viewpoint, in order to evaluate the acoustic characteristics of the performance space of special exclusive-use for Korean Classical Music, based on the subjective response which reflects human being's psychological attribute at first, this Study has attempted to extract the proper evaluation vocabulary for appraisement on Korean Classical Music. The abstracted vocabulary in such way would be used significantly for Subjective Response Evaluation in order for the evaluation on the Acoustic Characteristics of the performance space of special exclusive-use for Korean Classical Music.

This research aims to analyze the characteristics of the architectural space of Rem Koolhaas based on the spatial discourse of Gilles Deleuze, a philosopher of post-structuralism which comprehends pluralism accepting even contingency and uncertainty beyond deterministic attitudes of structuralism that has led the western discourses since the 19th century. First of all, this research will reflect on Deleuze's spatial concept through literatures and extract the characteristics related to architectural spaces. Then, on the basis of these characteristics, it will analyze the characteristics which were applied to the interior space of the recent architectural works of Rem Koolhaas to find out how Deleuze's spatial dicourse was embodied. Among Deleuze's speculations, the characteristics which falls under the spatial discourse were classified into three categories; degree between the striated space and the smooth one, the space of events and singularity, and the space of the multiple sense. These analysis words are used to look into the correlations among the specific practicing methods embodied in the architecture of Kookhaas. In conclusion, in the architectural space of Rem Koolhaas, it was found that the characteristics of Gilles Deleuze's spatial discourse of post-structuralism were embodied by the methods such as (1) Space of continuous transition, (2) Space of the $multiplicit{\acute{e}}$ accepting contingent events, (3) Space of the multiple sense, and (4) Space of movement.

Achieving the beneficiary goal of recent discovery in human genome project still needs a way to retrieve and analyze the exponentially expanding bio-related information. Research on bio-related fields naturally applies knowledge discovered to the current problem and make inferences to extract new information where shared concepts and data containing information need to be defined and used in a coherent way. In such a professional domain, while the need to help users reduce their work and to improve search results has been emerged. methods for systematic retrieval and adequate exchange of relevant information are still in their infancy. The design of our system aims at improving the quality of information retrieval in a professional domain by utilizing both corpus-based and concept-based ontology. Meta-rules of helping users to make an adequate query are formed into an ontology in the domain. The integration of those knowledge permits the system to retrieve relevant information in a more semantic and systematic fashion. This work mainly describes the query models with details of GUI and a secondary query generation of the system.

The Earth's magnetic field acquired from KOMPSAT-1's TAM (Three-Axis Magnetometer) between June 19th and 21st 2000 was analyzed. The TAM, one of the KOMPSAT-1's Attitude and Orbit Control Subsystems, plays an important role in determining and controlling the satellite's attitude. This also can provide new insight on the Earth's magnetic field. By transforming the satellite coordinate from ECI to ECEF, spherical coordinate of total magnetic field was achieved. These data were grouped into dusk (ascending) and dawn (descending) data sets, based on their local magnetic times. This partitioning is essential for performing 1-D WCA (Wavenumber Correlation Analysis). Also, this enhances the perception of external fields in the Kompsat-1's TAM magnetic maps that were compiled according to different local. The dusk and dawn data are processed independently and then merged to produce a total field magnetic anomaly map. To extract static and dynamic components, the 1-D and 2-D WCAs were applied to the sub-parallel neighboring tracks and dawn-dusk data sets. The static components were compared with the IGRF, the global spherical harmonic magnetic field model. The static and dynamic components were analyzed in terms of corefield, external, and crustal signals based on their origins.

In the literature, various stochastic anomaly detection methods, such as limit checking and PCA-based approaches, have been applied to weld defect detection. However, it is still a challenge to identify meaningful defect patterns from very limited sensor signals of laser welding, characterized by intermittent, discontinuous, very short, and non-stationary random signals. In order to effectively analyze the physical characteristics of laser weld signals: plasma intensity, weld pool temperature, and back reflection, we first transform the raw data of laser weld signals into the form of event logs. This is done by multidimensional discretization and event-codification, after which the event logs are decoded to extract weld defect patterns by $Na{\ddot{i}}ve$ Bayes classifier. The performance of the proposed method is examined in comparison with the commercial solution of PRECITEC's LWM$^{TM}$ and the most recent PCA-based detection method. The results show higher performance of the proposed method in terms of sensitivity (1.00) and specificity (0.98).

Numerous studies have been conducted to analyze the causal relationships of maritime accidents using natural language processing techniques. However, when multiple causes and effects are associated with a single accident, the effectiveness of extracting these causal relations diminishes. To address this challenge, we compiled a dataset using verdicts from maritime accident cases in this study, analyzed their causal relations, and applied labeling considering the association information of various causes and effects. In addition, to validate the efficacy of our proposed methodology, we fine-tuned the KoELECTRA Korean language model. The results of our validation process demonstrated the ability of our approach to successfully extract multiple causal relationships from maritime accident cases.

Objectives : The purpose of this study was to investigate the anti-aging effects on cultured human keratinocytes with Nelumbo nucifera extracts. Methods : Each parts of leaves, flowers and stamen were extracted with water or 70% ethanol. These extracts were tested for cell viability on HaCaT cells (human keratinocyte line) by MTT assay. We investigated the effects of Ultraviolet-B (UVB) irradiation on cytotoxicity and lipid peroxidation in cultured skin keratinocytes. Results : The ethanol extract of Nelumbo nucifera flowers showed maximun cell viability as 111.39% in 30 ug/ml concentration. The water extracts of stamen, flowers, leaves showed cell viability as 107.12, 101.65, 101.46%, respectively. HaCaT keratinocytes were survived 63.06% at $20mJ/cm^2$ UVB irradiation. The cell membrane lipid peroxidation was measured by accumulation malondialdehyde (MDA). The levels of MDA were decreased by the ethanol extract of Nelumbo nucifera flowers and the water extracts of stamen. Conclusions : These finding suggest that the ethanol extract of Nelumbo nucifera flowers prevent anti-aging effects on cultured human keratinocytes during UVB irradiation.
