Dressmaking is a high value-added sector of the fashion industry in which the individuality and skills of designers play a prominent role. The appropriate use of the draping and the flat pattern techniques in the dressmaking process also play an important part in perfecting the finished product. The purpose of this study was to improve the understanding of dress design and identify a pattern production technique to enhence efficiency in each of the three elements of the dress manufactureing process. For this purpose, analysis of the design of 1,389 wedding dress photographs published in Wedding 21, Korea's leading wedding magazine, during 2019 and 2020 was conducted. This analysis identified 15 bodice designs and 11 sleeve designs based on neckline and eight skirts based on silhouette which were ranked by frequency distribution. Patterns for the design of samples were then developed according to the highest combined frequency distribution of these three elements. Eight samples were finally produced to test the the efficiency of the patternmaking techniques empolyed and the selected designs. The findings from this study have practical applications, notably in improving the efficiency of pattern production techniques that will facilitate further growth in the dressmaking industry.

The annual increasing rate of visitors was 9.5% in Odaesan National Park from 1989 to 1995. Ninety three percent of total visitor of Odaesan National Park has visited Woljongsa and Sogumgang area in which a motorcar access is convenient. Climbing rate of Pirobong(peak) were less seven percent of total cisitors at Woljongsa in summer and less twelve point six percent in autumn. Visiting pattern showed difference by area, seasons and a day of the week. Using rate of motorcars was higher in summer than in autumn

The purpose of this study is to analyze the principal causes of vibration problem and find out the method of vibration reduction in a chip-mount system. The principal causes are investigated through measurements of vibration spectrum and model parameters. Modal parameters are obtained by using an experimental model test. Based on the model parameters from experiments. a model of finite element method is formulated. The model presents effective redesign of increasing the natural frequencies in order to reduce the vibration of a chip-mount system. Further, through computer simulation for the behavior of head to be main vibration source, the best acceleration pattern of head movement can be verified to achieve effective head-positioning and reduce the vibration due to head movement.

As the software industry develops at a rate speed, anyone can copy or plagiarize without difficulty contents that are becoming digitalized. To make it worse, the development of various contents that be illegally copied and plagiarized are resulting in the increasing infringement on and the plagiarism of the intellectual property. This dissertation tries to put forth the method and the theory to effectively detect any plagiarism of the source code of programs realized in various languages. This dissertation analyzes the advantage and disadvantage of the plagiarism test software, and especially, presents a method to detect possible plagiarism by using the Pattern Matching to overcome its disadvantage. And it also intends to introduce more developed automatic detection system by overcoming the problems with the method of Pattern Matching.

The purpose of this study is to fined out the characteristics of using & change of the residential space according to the children age and family life cycle. The results of this study are as follows: The first, as children grow up, children's activity space changed from living room to the private room, and housing condition was related to the frequency of each activity. The second, as children grow up, family's sleeping pattern changed, and this change effected the number of private rooms for sleeping and the use of the extra room. The third, changes of the using of dwelling space come out several pattern, increasing bedroom number through reconstruction, exchange of An-band and children room, parents' sleeping space move to living room, and change the function of rooms. The change pattern of the correspondence to the housing needs differed from each family life cycle stage.

There are increasing a foreign visitors since 88 Seoul Olympic game. Uniform is getting increased importance as one of the symbols which represent the characteristic of restaurant as well as gloves good impression to the customers and foreign tourist. This study aims at developing uniform packages (including table cloth, mat, napkin, end so on) that satisfy the customers' need and let foreign visitors recognize the outstanding beauty of Korean traditional pattern. For uniform design, It was selected a sumacsae of a the lotus flower motif and developed a textile pattern design by using CAD system. And then the developed textile design was printed a polyster100% fabric by using the digital textile printing system. Uniform packages designs were developed applying traditional sumacsae motif in order to capture a modern stance of beauty under using blue and pink color and same concept of modern image.

Interpattern association (IPA) model which the interconnection weight matrix(IWM) is constructed by the association between patterns is effective in similar pattern recognitions. But, if the number of reference patterns is increased, the ability of recognition is decreased. Using a hierarchical recognition algorithm which adopts the tree search strategy, we classified reference patterns into sub-groups by similarity. In IPA model, if input includes random noise we make it converge to reference pattern by means of input includes random noise we make it converge to reference pattern by means of increasing the number of pixels of prohibited state in IWM. In relation to reference patterns the pixel of prohibited state made partially prohibited state of no connected state using which is not included common and feature regions by each reference patterns.

We fabricated surface pattern on a light guide panel (LGP) using $CO_2$ laser to improve the luminescence performance of inner-scatterer LGP, which is made of PMMA sample with exploiting Q-switched $2^{nd}$ harmonic Nd:YAG laser engraving system, and the effect of surface pattern in the brightness distribution of LGP was analysed. To prove the feasibility of proposed method in the enhancement of LGP performance, we designed three different surface patterns on the inner-scatterer LGP. The experimental results has proved the potential in the application of surface pattern to increasing the brightness of inner-scatterer LGP.

The annual increasing rate of visitors was 3 percent in Soraksan National Park form 1990 to 1997. Secenty nine percent of total visitors in Soraksan National Park has visited Oysorak district due to convenient access and facilities. Approximately, 6~17 percent of visitors passing through Sorakdong ticket office at Oysorak district has climbed up Taech'ongbong(peak), the others have visited Ulsanbawi, Pisondae and Madungnyong close at hand. Climbers from Osekyaksu to Taech'ongbong(peak)were more in autumn than in summer. Visiting pattern in Soraksan National Park showed differences by districts, seasons and days of the week.

Plastic, the main material of FFF-type 3D printing, exhibits lower strength compared to metal. research aimed at increasing strength is needed for use in various industrial fields. This study analyzed three X-shape infill patterns(grid, lines, zigzag) with similar internal lattice structure. Moreover, tensile test considering weight and printing time was conducted based on the infill line multiplier and infill overlap percentage. The three X-shape infill patterns(grid, lines, zigzag) showed differences in nozzle paths, material usage and printing time. When infill line multiplier increased, there was a proportional increase in tensile strength/weight and tensile strength/printing time. In terms of infill overlap percentage, the grid pattern at 50% and the zigzag and lines patterns at 75% demonstrated the most efficient performance.
