  • This study presents the results of series of studies, which are mainly devoted to the application of wavelet transforms to various problems in ocean engineering. Both continuous and discrete wavelet transforms were used. These studies attempted to solve detection of wave directionality, detection of wave profile, and decoupling of the rolling component from free roll decay tests. The results of these analysis, using wavelet transform, demonstrated that the wavelet transform can be a useful tool in analyzing many problems in the filed of ocean engineering.

  • Kyu-Soo Park wrote the book "Gur Ga Jap Bok Ko" (Proposition for Household Casuals) around A.D. 1865. He was a widely-learned man and a proponent of Korean self-consciou-seness like his fellow Pragmafist against then prevailing Chinese influence, which had already penetrated deeply into ordinary life style. According to this fact we can see not only the general dress-cystoms but the new customs of some high-birth People with evident self-consciouseness like him at that time. For example, they wore "Sim Eui" and "Bok Gun" as the dress of their ordinary life in spite of the general dress custom wearing the "Do Po" (Traditional Korean full-dress attire) and "Gat" (Traditional cylindrical Korean hat) as an ordinary or a ceremonial dress irrespective of rank at that time. Women wore an overcoat with "Chima" and "Jur. Go Ri" instead of the shortened "Jur, Go Ri" and buttock exagerating "Chima" largely popular at that time too. And also wore "So Eui" instead of "won Sam" or "Dang Eui" prevailing for the psychological resemblance of higher ranking group. Male yougnsters wore "Sa Gyu Sam" as an ordinary life dress and Girls wore "Chima and Jur Go Ri".

  • Severe soybean-sprout rot was found at the mass productive factory in 2000 and 2001 and it caused 10-20% loss of the production. Pythium sp. was isolated almost 90% by potato dextrose agar from rotted root and hypocotylsof the sprouts. And the pathogencity tests using test tubes with 2% water agar and small containers (30 ${\times}$ 30 ${\times}$ 50 cm, WxLxH) cultivation were shown a similar rot on roots and hypocotyls. The fungal mycelium grew rapidly on the water agar and it prevented the seed germination. Density of the Pythium sp. in the recycled water system at the factory was periodically measured using a selective medium, corn meal agar with Pimaricin 10 mg, Rifampicin 10 mg, Ampicillin 100 mg per 1 liter in order to check the contamination of recycled water. After fitering step using 5 and 1 ml in the recycled system was applied and it was effectively controlled Pythium rot. The daily yield of sprout was stable and the occurrenceof Pythium in the recycled water was much less after filtering. The fungal isolates were identified as Pythium deliense Meurs based on various mycological characteristics on corn meal agar and sucrose-asparagine bentgrass leaf culture medium. P. deliens oogonia were spherical, smooth, 19-23 urn in diameter, and their stalk bending toward antheridia. Antheridia were straw hat-shaped, curred club-shaped, therminal or intercalary, monoclinous, occasionally diclinous, 12∼15 ${\times}$ 8∼11 um, 1(∼2) per oogonium.

  • This study is a discussion of the expressive characteristics of contemporary fashion design with floral images. It aims to help understand the overall trends of contemporary fashion design and textile motif design and expand the potential expression fields of originative design to natural objects such as flowers. Methodologically the study analyzed 976 pieces of data gathered from Haute Couture and Pr$\hat{e}$t-$\grave{a}$-Porter collections of 2005S/S-2009F/W, according to their types of expression. The study results show a share of 42.7% for plane type expressions by printing or weaving and a share of 51.5% for relief type expressions, compared with 5.7% for solid type expressions. However, those expressions represented elegant femininity with emphasis on formative beauty and were applied to fashion accessories or hair adornments. The expressive characteristics found from the analysis were represented by natural images, feminine elegance, and decorative aesthetics of handicrafts. Flowers in the contemporary fashion purify the internal emotions of humankind stand for personality and beauty in many different ways of expression and serve as a means of expressing more artistic values breaking out of stereotype.

  • This study is on the various style and characteristics of mask, and was performed empirically by reviewing the related materials such as the literature, precedent studies, fashion works, and home and foreign fashion magazines. As a result of the study, the style of mask in the modern fashion is roughly categorized by full-covered style, half-covered style, and over-half-covered style which is covered over 50% of a face. And, mask is utilized on a hat or a dress all over, or is produced by a elaborate makeup. Mask with lots of variation has three big characteristics, which are sense of disguise, sense of ornamentation, sense of grotesquery. First, sense of disguise means deviation or tool of affectation instead of cultural standard norm through transforming or masquerading as an imagery person or animal in ancient myths, famous artistes, etc. It could be developed to express a designer's identity. Second, mask decorated with various styles and materials has sense of ornamentation, which means natural human desire of expression for beauty, and at the same time human mind longing for experience a fantastic and ideal inner world being deviated from the present world even indirectly. Third, ignoring the original format of eyes, nose, and mouth, using extraordinarily various techniques such as distortion, extreme, exaggeration, concealment, or combining with animal images, mask has sense of grotesquery inducing humor and horror simultaneously.

  • This study conducted to tried to find a way of on-line assessment of learner's interest and comprehension during interactive learning process. The result of experiment confirmed hat learners' behavior patterns acquired from log data could be good predictors of learner's level of interest and comprehension in actual performance on KORI program. To predict learning outcome depending on the behaviors of individual learners, self-efficacy and mastery goal orientation were measured as individual differences. Then, participants were asked to use TA program KORI program at home for ten days and their response patterns were recorded through network. After using KORI, the levels of interest and comprehension were measured. As the result of multiple regression analysis, each learner's interest and comprehension were predicted depending on the combination of log data captured on real-time. This prediction process was done differently depending on learners' characteristics. Since equations which predict learners' interest and comprehension are different depending on learners' characteristics, differential interfaces should be provided depending upon changes in their level of interest and comprehension.

  • ln general, hospital information system should provide interoperability hat usually and operate independence of other HIS. This study proposes a new HIS paradigm that can be implemented within standard HL7 Interface engine and clinical data repository (CDR). We have developed an alternative architecture relying on agent solutions with distributed queries to heterogeneous databases. This architecture creates a very fine and flexible repository that can handle queries with the bases of standard HL7 messaging structure. Deploying Agent solutions to manipulate autonomy of storage management and sociality for communication with open world is another issue that keeps this system from reinventing existing wheels in medical informatics. This study the first attempt to construct CDR based private clinic. We used the information stored in the clinical patient record system of the internal medicine private hospital which is used rational database. We were searched increasing the 1,000 data entry from 1,000 to 10,000. By the result, experimental CDR showed highly efficient performance more than 6,000. In the future, the CDR can be further extended for clinical information among private hospitals estranged from EHR (Electronic Health Records).
