In the recent years number of commercial off-line character recognition systems have been appeared in the Korean market. This paper describes a "self -organizing" data structure for representing a large dictionary which can be searched in real time and uses a practical amount of memory, and presents a study on the character correction for off-line printed sentence marks, Japanese, English, and Chinese character recognition. Self-organizing algorithm can be recommenced as particularly appropriate when we have reasons to suspect that the accessing probabilities for individual words will change with time and theme. The wrongly recognized characters generated by OCR systems are collected and analyzed Error types of English characters are reclassified and 0.5% errors are corrected using an English character confusion table with a self-organizing dictionary containing 25,145 English words. And also error types of Chinese characters are classified and 6.1% errors are corrected using a Chinese character confusion table with a self-organizing dictionary carrying 34,593 Chinese words.ese words.

In the ATs(Auto-Transformers)-fed AC electric railroad system, the trolley wire with high power is supported with a messenger by the dropper. As the dropper maintains the height of the trolley wire and plays a role in distributing the supply power, it should be stabilized in that an electric and mechanical character accord ins the change of the open air circumstance and constructed easily. Consequently, this paper propose C5111 Sn(3.5$\sim$4.5%) and hexagonal round bolt for the way of the efficient stabilization as a result of the test that the correlation of the Sn content and the change of temperature affect a character of product.

As materials on the river bed have been changing through erosion, transportation and accumulation, so does the waterway's section. So many bridges have nowadays been constructed to the same direction as water flows. However further researches are still needed on the scours of succession row piers and multiple row piers. Analyzing them through hydraulic stimulation experiments, this study deals with the scour character with the change of diameters in row piers which have been built in the identical direction of water flow and also the part-scour character change in multiple row piers.

As elderly population has been increasing, our society has to be prepared the social system. Especially female elderly increasing means that market will change and business model should also change. Every women want to be beautiful and looks young and as women get aged, women eager to be younger and beautiful more. The purposes of this study were to find out how was represented in cosmetic market ad and how elderly customers has been changed. In developed society, baby boomer has been increased, and their power of purchase also has been increased in cosmetic market. In our society, cosmetic market has been developing as customer's demand and whitening focused cosmetics has been increasing especially. Elderly skin need more moisture focused cosmetics and for developing the elderly cosmetic market in Korea, we need more research about korean elderly women's social psychological character and customer's character.

The purpose of this study is examining a circulation and conflict of concepts and logics of the $Chos{\check{o}}n$-ness by analysing the $Chos{\check{o}}n$ national character and $Chos{\check{o}}n$ aesthetic consciousness. As entering the modern period, we understood the nations as a unit of the artistic awareness. So, national art is defined as a national character expression from this period. The $Chos{\check{o}}n$ aesthetic consciousness by raising in this period, which is connected with the discourse of national character, carry out a discussional practice defining the Korean originality. However, there is a circulation and conflict of concepts and logics about the $Chos{\check{o}}n$ aesthetic consciousness in the process of a discussion. For the most representative examples are 'the white-clad folk' and 'the beauty of sorrow'. An Hwak and Yanagi Muneyoshi are representative debaters who try to establish the $Chos{\check{o}}n$-ness and their discussion supports these facts. As An Hwak regressing of the respect for high antiquity, he demolished the historical character from the $Chos{\check{o}}n$-ness and overlooked aesthetic differences by a periodical change. Yanagi Muneyoshi totally separates arts from politics and disposes of Korean arts in an abstract timeless-space. The function of such an early-modern period's discourse about $Chos{\check{o}}n$ aesthetic consciousness is that $Chos{\check{o}}n$ national character makes the dehistoricization and depoliticization.

In this paper, we realized a system that converts the character images of the printed Korean alphabet (Hangul) to the editable text documents by using the black and white CCD camera, We were able to abstract the contours information of the character which is based on the structural character by using the boundary tracing technique that is strong to the noise on the character recognition. By using the contours information, we recognized the horizontal vowels and vertical vowels of the character image and classify the character into the six patterns. After that, the character is divided to the unit of the consonant and vowel. The vowels are recognized by using the maximum length projection. The separated consonants are recognized by comparing the inputted pattern with the standard pattern that has the phase information of the boundary line change. We realized a system that the recognized characters are inputted to the word editor with the editable KS Hangul completion type code.

This paper presents a novel on-line trajectory optimization framework based on automatic time warping, which performs the time warping of a reference motion while optimizing character motion control. Unlike existing physics-based character animation methods where sampling times for a reference motion are uniform or fixed during optimization in general, our method considers the change of sampling times on top of the dynamics of character motion in the same optimization, which allows the character to effectively respond to external pushes with optimal time warping. In order to do so, we formulate an optimal control problem which takes into account both the full-body dynamics and the change of sampling time for a reference motion, and present a model predictive control framework that produces an optimal control policy for character motion and sampling time by repeatedly solving the problem for a fixed-span time window while shifting it along the time axis. Our experimental results show the robustness of our framework to external perturbations and the effectiveness on rhythmic motion synthesis in accordance with a given piece of background music.

The objective of this study is to investigate the characteristics of natural indigo dyeing of cotton fabric. Reduction and dyeing were carried out by one-step process using an infrared dyeing machine at the liquor ratio of 1:100, and subsequently oxidation and washing in water were followed. Dye uptake was increased with the increase of indigo concentration. Over the full range of dyeing tests, the dyeing condition was optimized to $40^{\circ}C$ for 40min. For most of dye concentrations, the cotton fabrics showed mainly PB color. Maximum K/S value was shown at 4g/L of sodium hydrosulfite concentration and the color strength increased with the increase of dye concentration. Value(lightness) decreased with the increase of dye uptake irrespective of mercerization or reduction method, while the mercerized cotton showed two times higher dye uptake than the untreated cotton. Whereas hue of the untreated cotton showed large decrease of P character(5.6~3.5 PB) with the increase of dye uptake, that of the mercerized cotton increased P character(4.7~5.5 PB). Irrespective of mercerization, value and chroma decreased with the increased of dye uptake. In addition, the untreated showed lower chroma than the mercerized cotton. In the case of traditional reduction, hue of the untreated cotton was changed very little with the increase of dye uptake. For hydrosulfite reduction, P character decreased with the increase of dye uptake. The difference of hue value was small with the change of reduction method(hydrosulfite reduction or traditional fermentation). Color character was not influenced by the changed maximum absorption wavelength. Washing fastness showed 4~4/5 shade change rating without any staining. And dry rubbing fastness was good at low color strength. The bacterial reduction ratios of dyed cotton fabric were also increased.

The FPS, featured with high quality graphic of superior visual reality, is steadily growing because of the improvement of computer performance and technological advancement of game production. But most of the FPS games provide monotonous freedom with which players can only change the weapons in one character and this will make users lose their interests when playing games for long hours. Valve has introduced 'Team Fortress Classic' in 1999, in order to change the monotonous game methods. This game has attracted great attention because of the composition of various and unique characters through the introduction of military specialty system: that is the first trial in the history of FPS game. I, by analyzing this using MBTI, intend to analyze how much of immersion and interest the characters of various military specialties can provide to players when FPS games are developed.
