This study is to develop tourist souvenir which designed image of butterfly, the symbol of Hampyeong Butterfly Festival, using natural dyeing product, the specialty of Namdo region. Results of market survey of tourist souvenirs for Hampyeong Butterfly festival showed that souvenirs of butterfly design sold in market which were not discriminated from that of general products and locality or characteristic of the region could not be exhibited. According to the results of market survey, design of souvenirs of Hampyeong Butterfly Festival is as follows; Butterfly pattern of hinge and Dangcho pattern are developed to graphic motive of modern sense with traditional beauty to make design which can be consumed by modern consumers in their actual life and then proper pattern is planned by combining, repeating and disassembling them. Such a pattern is applied to souvenirs like T-shirts, necktie and scarf to make tourists feel identity and unification of the festival visually. In addition, design of souvenirs was made to be coordinated with casuals. Therefore, visual factor could be extracted from Korean cultural heritages suitable to concept of local festivals and it is considered that ways of commercialization and development of traditional pattern suitable to consumers' demands can be suggested.

The study reveals the extent of changes in selective financial numbers caused by fixed asset revaluation (FAR) and explores whether there was a management motive for playing the financial numbers game through using the FAR model. The data set consists of a sample of 142 listed companies purposively selected from 13 industries. The study found a significant impact of FAR on the net asset value (NAV), fixed asset intensity (FAI), and debt-to-equity ratio (DER). These findings are supported by the political cost and the debt covenant hypotheses. The study also observed a high growth of fixed assets by 9.5% to 14,603.8% resulting from FAR. More revealing is that FAR increased NAV in revaluer companies by an average of 427.20% as compared to 6.86% in non-revaluer companies. Even some companies with negative NAV took resort on FAR to show positive NAV. Besides, revaluer companies managed to reduce their DER by 70.45% as opposed to an increase of 8.45% in non-revaluer companies. Hence, the study concludes that most of the publicly-listed companies are involved in financial numbers game by the use of the FAR model. To build confidence among investors, companies should practice FAR rightly and disclose related information to help reduce information asymmetry.

When evaluating acoustic methods for measuring physical parameters in the ocean, economical and technical considerations are paramount. As an indirect method of estimating ocean dynamics, acoustic tomography has advantages over more conventional approaches. It allows the reconstruction of temperature and flow fields from the acoustic impulse time-of-flight measured along the rays propagating from the source to the receiver. However, many problems require complicated and expensive systems. To use the acoustic tomography method to best effect, developing hardware systems with sources and receivers mounted permanently on the sea bottom is crucial. Akulichev et al. presented some experimental results from shallow zones of the World Ocean that served as a motive for developing a multifunction system with acoustic hardware and software. Here we present technical features and the sea test results of the system.

In this paper, a four-phase 8/6-pole 4-kW SR motor drive model is presented. Based on experimental data, the model allows an accurate simulation of a drive in dynamic operation. Simulations are performed and a laboratory type set-up is built based on a TI TMS320F2812 platform to experimentally verify the theoretical results obtained for a SR motor. To reduce acoustic noise and to correct the power factor of this drive, a two-stage power converter is proposed that uses a current source rectifier (CSR) as the input stage for the asymmetrical converter of the studied SRM. Employing the space-vector modulation (SVM) method in matrix converters, the CSR switching allows the dc link's capacitors to be eliminated and the power factor of the SRM drive to be improved. As the electrical motive force (emf) is directly proportional to the rotor speed, the input voltage to the machine can be programmed to be a function of the speed with the modulation index of the CSR, leading to a reduction in the acoustic noise of the SRM drive. Simulation of the whole SRM drive system is performed using MATLAB-Simulink. The results fully comply with the required conditions such as power factor correction with an improvement in the THD.

This paper deals with the optimum design of the stator and rotor shape of the interior permanent magnet synchronous motors (IPMSM) that are used in applications for automobiles. IPMSMs have the following advantages: high power, high torque, high efficiency, etc. However, cogging torque which causes noise and vibrations is generated at the same time. The optimum design of shape of a IPMSM was carried out with the aim of reducing cogging torque. Six variables which affect to the performance of a IPMSM are chosen. The main effect variables were determined and applied to the response surface methodology (RSM). When compared to the initial model using the finite elements method (FEM), the optimum model highly reduces the cogging torque and improves the total harmonics distortion (THD) of the back-electro motive force (EMF). A prototype of the designed model was manufactured and experimented on to verify the feasibility of the IPMSM.

This study suggests through an examination of maternity wear sold in domestic markets a design for maternity wear trousers that integrate functionality, aesthetics, and marketability. This study targeted women who had maternity wear experience to obtain basic information for the design of maternity wear trousers. This study conducted questionnaire research on maternity wear and surveyed the growing on-line maternity market. The results are as follows. First, in the questionnaire research on wearers of maternity wear, women 26-35 years old were the main consumers and emphasized comfortableness as the significant reason for buying and using maternity wear. Second, the centering on pants were evaluated to be the most uncomfortable item among maternity wear and confirms the necessity for a maternity wear design whose bodily fitness is high according to the trouser panel. Third, a standard for the specific design was established to solve maternity wear problems based on the analyzed information. This was established by having a concept as a minimal motive in 'new naturalism' that is the aesthetics of slackness for the $21^{st}$ century. A specific design was developed with 6 kinds for skirts and 9 kinds for pants.

This study aims to examine current status of cultural products in Mokpo city and their problems and develop cultural products design suitable to this situation. Cultural products in Mokpo sold here are made from China and have lower quality or traditional crafts and folkcrafts which can be purchased anywhere in Korea and they are not enough to show identity or image of Mokpo city. So I mixed the logos of 'mokpo city' and 'national maritime museum' based on main motive of 'modern Korean ship and shipbuilding tools' held by 'National Maritime Museum' and 'Goebukseon (turtle ship)' and 'Hanseon' which are suitable to the image of maritime culture as cultural products advocated by Mokpo city and developed one design style for print. This design is applied to T-shirts, necktie, cap, cushion and mug. Silk print, transfer print and needlework techniques are applied to each item and the whole cultural products have design of set concept. It is a case of applying modern product marketing technique to our cultural products not a design for only one item, is aimed to recreate spiritual and cultural value that a region has as daily goods to be used by general consumers and show the chance and possibility to complement shortcomings of existing cultural products and develop traditional culture having locality.

This study aimed at examining the pattern and detailed formation of corset look which has established itself as a sort of fashion look as people began to wear underwear as part of outer garment. The study tried to present basic materials helpful for developing and creating the design and pattern of corset look. First, the collected corset look of each brand was copied and then developed. According to the result, corset look's representative silhouette turned out to be hourglass silhouette that tightened up the waist with an emphasis on expressing the beauty of the body. However, unlike corsets of the past, corsets today are being created with focus on the design rather than using lots of incision lines. Second, The bust girth of corset look items turned out to have little function to compress and deform the body like the corset of the past that was far smaller than the body. In addition, the corset style that used the lines of corset alone as motive turned out to have the larger waist girth. Third, the dismantling of collected corset look showed that the materials and formation features of corset look have become simple and that the simplification of corset look has made the items of corset look everyday clothes which can be worn practically and universally.
