This paper investigates how Korean newly-composed pieces (Changjak Gukak) can be used as good cultural contents to publicize a characteristic and nowness of Korean culture in the era of globalization, focusing on the works of composer Seong-Cheon Lee. LEE Seong-Cheon is a typical Changjak Gukak composer who academically and creatively speculated Korean tradition and identity. In his works, traditional ones, natural-thematic ones, nationalistic ones, and Korean literary-thematic ones are the works which have a possibility to use cultural contents with respect to the Korean traditional culture and identity. This study dealt with the fact that newly-composed pieces based on traditional music can play a significant role in expanding Korean cultural contents between tradition and modern.

A study on the amount, distribution and item of bottom litter on the sea-bed was conducted by the bottom trawl net at 5 sections in Chinhae Bay over a year. The number and weight of litter found per unit of swept area (1 hectare) in each section were estimated as the range of 8.76-80.63 pieces, 3.51-108.39kg, respectively. The seasonal variation of high (Aug., '97) and low season (Feb., '98) in quantity was small, and it was about 2 times as the range of 24.58- 52.61 pieces/ha between them. But the weight variation between high (Apr., '98) and low season (Aug., '97) was very large, about 30 times as the range of 4.06-119.64kg/ha. The largest and second composition on the weight of bottom litter in Chinhae Bay are $76\%$ in other-litter with compound and bulky materials, and $93\%$ in fishing gear, respectively. The relationship between quantity and weight of bottom litter was not occurred due to the variety of specific gravity. Of the fishing gear, fishing nets was portioned to be 2.571kg/ha in weight and $84.9\%$ in composition. So these results prove that fishing nets were discarded as the most part of fishing gear during fishing activity in the bay. The largest composition of the soiled state classified into 3 styles in overall bottom litter was $69\%$ in very soiled state, and the second one of $28\%$ in the soiled state. On the other hand, new state is very small and portioned in $3.0\%$ of all. Chinhae Bay was estimated to be about 10 times in quantity and about 36 times in weight of Tokyo Bay. Therefore, these suggest that Chinhae Bay is a very serious polluted estuary caused by the bottom litter such as heavy and bulky wastes, fishing gear.

Floating debris was observed using a training ship, KAYA, of Pukyong National University with cruising speed of about 10-12 knot during July 12~25, 2003. The area sampled was the East Sea enclosed by 3 nations, namely, Korea, Japan and Russia, and was divided into 68 unit segments on survey routes [Fig. 1]. Debris fabrication materials were categorized with 6 items, e.g., man-made or natural wood items, paper and cardboard, nylon rope, styrofoam, vinyl and plastic, floating metal and glass containers. All identified items within $100{\pm}10 m$ wide band were recorded but ignored if beyond this boundary. The results of this study are as follows: 1. The average numbers of debris per unit area, $1km^2$, were found as 16.3 pieces (items) in the sea. 2. The highest densities of numbers, $32.3pieces/km^2$, were discovered in vicinity of the Oki strait of Japan, area of 'NEK' in Fig. 1. 3. Especially, styrofoam item only was composed to 63.6% of all in the sea of 'SD', located in the southern part of Dokdo Island, Korea. The item seems to be derive from the Southern Sea of Korea. 4. Therefore, comparing the distribution of debris numbers (the results of above 2 and 3) with flow patterns of Kuroshio currents, it was shown that their relation was good agree each other. Further more surveys are being conducted and a much wider coverage can be achieved with other countries, then it can be obtained that the East Sea is polluted to some extent, where is the origin of debris, and the finding of floating routes and stationary sea.

Ice rubble pieces broken by the bow impact load and side hull of an icebreaking vessel usually pass along the ship's bottom hull and may hit the propeller/rudder or other stern structures causing serious damage to ship's hull . Therefore it is important to estimate the size of broken ice pieces during the icebreaking process. The dynamic interaction process of icebreaker with infinite ice sheet is simplified as a wedge type beam of finite length supported by elastic foundation. The wedge type ice beam is leaded with vertical impact forces due to the inclined bow stem of icebreaking vessels. The numerical model provides locations of maximum dynamic bending moment where extreme tensile stress arises and also possible fracture occurs. The model can predict a failure length of broken ice sheet given design parameters. The results are compared to Nevel(1961)'s analytical solution for static load and observed pattern of ice sheet failure onboard an icebreaker. Also by comparing computed failure length with the characteristic length, the meaning of ice rubble sizes is discussed.

This paper examines the works produced from 2000, the first year of the new millenium, to the late 2006 with a focus on those of Jean Paul Gaultier, a representative designer of deconstruction, in an effort to determine the aesthetic characters of deconstructional fashion. In this context, this paper deals with the theoretical study on the concepts and features of deconstruction as a part of analysis into its fashion using the works of Gaultier as a major source viewed to typically demonstrate the deconstructional characters of fashion. For this purpose, a survey was conducted to 155 works of Gaultier featured from 2001 to 2006 mostly in Vogue, the popular and influencing magazine of the USA(39 pieces in 2001, 30 in 2002, 29 in 2003, 23 in 2004, 12 in 2005 and 22 in 2006, respectively). In particular, 106 fashion pictures were put to analysis as they seemed to represent deconstruction intensively. The deconstructional characters of his works were examined in the categories of difference, inter-meaning, inter-textuality and decomposition on the basis of preceding studies, which resulted in the following outcomes: First, difference was found in 38 works out of 106 images, accounting for 36%, the biggest frequency; Second, inter-meaning accounted for 33% with 35 pieces, most frequently next to difference; Third, inter-textuality followed inter-meaning with 17 images or 15% in terms of frequency; Fourth, decomposition was revealed in 16 images in the same ratio of 15% as inter-textuality.

A piecewise linear regression model able to describe disease progress curves with simplicity and flexibility was developed in this study. The model divides whole epidemic into several pieces of simple linear regression based on changes in pattern of disease progress in the epidemic and then incorporates the pieces of linear regression into a single mathematical function using indicator variables. When twelve epidemic data obtained from the field experiments were fitted to the piecewise linear regression model, logistic model and Gompertz model to compare statistical fit, goodness of fit was greatly improved with piecewise linear regression compared to other two models. Simplicity, flexibility, accuracy and ease in parameter estimation of the piece-wise linear regression model were described with examples of real epidemic data. The result in this study suggests that piecewise linear regression model is an useful technique for modeling plant disease epidemic.

The purpose of this study was to study the beauty-coordination characteristics of Genderless fashion, which is emerging as a new trend by analyzing the trend in the latest collection and classify the resulting expression characteristics of make-up. Methods and scope of the study were based on collections published in the 2020 S/S season and 35 out of 84 designers with design elements were selected to analyze the garments most likely to be genderless. The characteristics of the expression of the genderless derived through this analysis were classified into compromise, androgyny, sensuality, exaggeration, enjoyment, and historicity. Compromise was the highest, and the lowest was for enjoyment of the classifications. The designer's work according to the characteristics of each expression shows that the pieces by Saint Laurent were the highest in compromise, sensuality, and historicity, and the pieces by Maison Margiela were the highest in androgyny while Balenciaga was the highest in exaggeration and enjoyment. Compromise represented a mixture of discord, such as incongruous bonding and coloring of heterogeneous materials, and androgyny led to the use of silhouettes and colors, with sensuality utilizing see-through material and incision lines allowing for physical exposure. Exaggeration intentionally destroyed the existing concept by breaking the overall balance of the human body through the enlargement of certain parts of the body, while enjoyment showed unexpectedness by destroying the line and sides of the garment. Lastly, historicity was analyzed for its retro design that transcends time and space with regional cultural and period characteristics.

As the distribution rate of the Smart mobile increased, the software technology and ideas for the ubiquitous systems advanced day after day to establish an environment where the public can easily access and experience such technologies. The communication between an individual and the many became more convenient through the social network services (SNS) and the individuals started to attempt to communicate in various methods. The communication methods and techniques became more diverse and the media art pieces focusing on the communications among many also became more interesting. This study attempted to create a prototype of the visual communication media art through the indirect participation of one of the widespread SNS, Twitter, for the communication and also to suggest the direct and indirect communication routes among the humans. In addition, the use of the typography in the pieces also attempted to examine a new type of work that combines the SNS and media art while delivering the text messages.

This paper introduces a new method for storing a private key. This method can be achieved by dividing the private key into "n" pieces by a (k, n) secret sharing method, and then storing each piece into photo files utilizing a steganography method. In this way, a user can restore a private key as long as he can remember the locations of "k" photos among the entire photo files. Attackers, meanwhile, will find it extremely difficult to extract the private key if a user has hidden the pieces of the private key into numerous photo files stored in the system. It also provides a high degree of user convenience, as the user can restore the private key from his memory of k positions among n photo files. Coupled with this, a certain level of security can be guaranteed because the attacker cannot restore a private key, even if he knows k-1 photo file locations.

Purpose: Distraction osteogenesis has been applied to the maxillofacial implantology and good experimental and clinical results have been reported. However, histologic studies of implants placement on distraction osteogenesis of atrophic alveolar ridges are scarce. In this study, we compare the bone formation between in the transport part and in the distraction part by histomorphometric analysis. Materials & methods: Three adult beagle dogs were served as experimental subjects. The 2 premolars and 1st molar were extracted on the Lt. side of mandible in each beagle dog. After one month later, osteotomy was performed and distraction device was adapted. Distraction was performed with gradual incremental separation of two bone pieces at a rate of 1.0mm per day for 5 days. During consolidation phase, new bone was formed in the distraction zone between the separated bone pieces. 5 weeks after distraction phase, 3 implants were placed in each beagle dog. The implants were inserted through transport part and distraction part and inferior basal bone. The animals were sacrificed at 2 weeks, 4 weeks, and 12 weeks after implant placement. BIC and BA of implants on distraction part and transport part were measured histomorphometrically. Results: BIC, BA increased after implant placement as time goes by passes and new bone formation was slightly higher in transport part than in distraction part at 2 weeks, 4 weeks after implant placement. At 12 weeks after implant placement, BIC, BA of were 74%, 61% in transport part and 77%, 59% in distraction part, therefore there were no difference in BIC and BA between transport part and distraction part at 12 weeks after implant placement.
