  • The subject basin of the research was the basin of Yeongcheon Dam located in the upper reaches of the Kumho River. The parameters of the model were derived from the results of abstracting topological properties out of rainfall-runoff observation data about heavy rains and Digital Elevation Modeling(DEM) materials. This research aimed at suggesting the applicability of the CELLMOD Model, a distribution-type model, in interpreting runoff based on the topological properties of a river basin, by carrying out runoff interpretation far heavy rains using the model. To examine the applicability of the model, the calculated peaking characteristics in the hydrograph was analyzed in comparison with observed values and interpretation results by the Clark Model. According to the result of analysis using the CELLMOD Model proposed in the present research for interpreting the rainfall-runoff process, the model reduced the physical uncertainty in the rainfall-runoff process, and consequently, generated improved results in forecasting river runoff. Therefore it was concluded that the algorithm is appropriate for interpreting rainfall-runoff in river basins. However, to enhance accuracy in interpreting rainfall-runoff it is necessary to supplement heavy rain patterns in subject basins and to subdivide a basin into minor basins for analysis. In addition, it is necessary to apply the model to basins that have sufficient observation data, and to identify the correlation between model parameters and the basin characteristics(channel characteristics).

  • In this paper, we present an ontology-based approach to labeling influential topics of scientific articles. First, to look for influential topics from scientific article, topic modeling is performed, and then social network analysis is applied to the selected topic models. Abstracts of research papers related to data mining published over the 20 years from 1995 to 2015 are collected and analyzed in this research. Second, to interpret and to explain selected influential topics, the UniDM ontology is constructed from Wikipedia and serves as concept hierarchies of topic models. Our experimental results show that the subjects of data management and queries are identified in the most interrelated topic among other topics, which is followed by that of recommender systems and text mining. Also, the subjects of recommender systems and context-aware systems belong to the most influential topic, and the subject of k-nearest neighbor classifier belongs to the closest topic to other topics. The proposed framework provides a general model for interpreting topics in topic models, which plays an important role in overcoming ambiguous and arbitrary interpretation of topics in topic modeling.

  • The growing market for geothermal heat pump system requires great consideration of quality control and assurance in design and construction. The borehole heat exchanger of GHP system should be sustainable, economical and ecological. Thermal Response Test (TRT) is a useful method for site investigation to obtain reliable data for a optimal system design from the technical and economical aspect. Intensive researches combined with exchange of experiences on an international level within the IEA ECES Annex 21 improved the technology. Major subjects on the interpretation of TRT are development of improved evaluation models, evaluation of the TRT with respect to geological layers and investigation of the influence of ground water. Current status of TRT in South Korea, as well as a new version of the Korean TRT standard test procedure was presented. TRT is mostly used for governmental supported projects with corresponds to more than 100 GCHP systems per year. More than 200 tests are applied, mostly on single U-tube heat exchangers (about 95%). Bentonite is the most common grouting to be used. KIGAM (Korea Institute of Geoscience & Mineral Resources) is also keeping a GIS geological and geothermal database. In the institute also laboratory measurements of rock properties are carried out. About 90% of the laboratory measurements of the rock heat conductivity shows higher values than the in-situ TRT.

  • The objectives of this study were to measure the preference and purchase intention on Korean traditional motifs and to investigate the relationship among preference, purchase intention, and sensibility. The subjects consisted of 217 male and 351 female US undergraduate students. The experimental materials used in this study were 48 stimuli and a questionnaire, composed of 7-point semantic differential scales of 17 bi-polar adjectives. The data were analyzed by ANOVA, Duncan's multiple range test, Regression, and t-test. The major findings were as follows; First, interpretation type and application object had significant effects on the preference, while category and interpretation type had significant effects on the purchase intension. The application of Korean traditional motifs for pattern design was preferred to their application for clothing design. Decorative type was found to be more related to the preference and purchase intention than the other interpretation types of realistic, stylized and abstract types. The purchase intention on crain motif was lower than the other categories of lotus and cloud motifs. Second, in overall, the preference on Korean traditional motifs was higher than purchase intention. Third, the preference and purchase intention were affected mainly by 'Quality' image, a component of sensibility, followed by 'Cheerfulness' image, but not affected by 'Simplicity' and 'Modernity' image.

  • For a commonly used piezocone with a shoulder filter element, dilatory dissipation behavior, which shows an initial temporary increase in pore pressure, has been observed in overconsolidated cohesive soils. However, there is no appropriate way to estimate a consolidation parameter from a dilatory dissipation curve because currently available interpretation methods were developed based on the monotonic decrease of the excess pore pressure. In this study, the interpretation method for evaluation of coefficient of consolidation from a dilatory dissipation result of piezocone test was developed by performing the finite difference analysis on the dissipation after cone penetration. The distribution of the initial excess pore pressure induced by cone penetration, which is the core of the analysis, was estimated from the empirical modification of a solution proposed by cavity expansion theory and critical state concept. And the proposed interpretation method was applied to the field piezocone data and the results were compared to those obtained from laboratory tests. Its reliability was confirmed by the insignificant difference between the values of coefficient of consolidation from piezocone tests and laboratory consolidation tests.

  • The purpose of this study is to prove an importance of systemic analysis paradigm to interpret fashion make-up. This research employed 'paradigm for interpretation of fashion make-up signs' theory to analyze data. This theory consists of three steps to interpret the meaning of a work: (1) recognition of form, (2) analysis of connotation meanings, and (3) analysis of symbolic meanings and communication. The results of this study were as follows. Jean Paul Gaultier's eye make-up uses a square pattern that mostly consists of the color black. He presents a Glam Rock image by using rimmed make-up that portrays an avant-garde and a nonmainstream culture. Jean Paul Gaultier's make-up was showing black color and square eye pattern and was presenting Glam Rock image and was a rimmed make-up meaning a nonmainstream culture and Avant-garde symbolically. Chanel's make-up emphasizes the eyehole with the rimmed technique by applying the make-up of Marchesa Casati and including non-popularity, Limited Marketing symbolically. Christian Dior's make-up applies the representative make-up of Joan of Arc and Siouxsie sioux and also uses rimmed make-up to portray the meaning of religion persecution, the dark-ages militarism and including Humanism symbolically.

  • The objective of this study was to investigate images of Korean traditional patterns. The subjects consisted of 369 male and 356 female undergraduate students. The experimental materials used in this study were 48 stimuli and questionnaires, composed of 7-point semantic differential scales of 23 bipolar adjectives. Twelve motifs selected from 3 groups of Korean patterns were used as motif stimuli. Twelve repeated patterns were constructed from them to be applied on a CAD-simulated dress. The data was analyzed by factor analysis, ANOVA, Duncan's multiple range test. The major findings were as follows: 1. Four dimensions were emerged accounting for the dimensional structure of the images of Korean traditional patterns. These dimensions were 'simplicity', 'quality', 'interest', and 'modernity' dimension. Among them, 'simplicity' and 'quality' were the major dimensions. 2. Category, interpretation type, composition type, and application object of motif had significant effects on the images of above-mentioned dimensions. The application object had a significant effect on 'simplicity' and 'modernity' image, and the composition type on 'quality' and 'interest' image.
