Since July 2007, the government has banned the use of the existing non-legal measurement units, and has forced us to use the unified legal measurement. Therefore, the existing clothing size unit also has been changed into centimeter dimensions from inches. However, consumers have been familiar to used to the traditional inches unit. So they have the confusion to directly survey the size table sign for clothing or to contact the employee when purchasing clothing. By the current size table sign the customers can compare the inches unit and centimeters unit, but they are difficult to see it. Therefore, there is necessary to improve the size table sign by the way that can be easy to be found and seen by consumers is given to the clothing corners. In this research, three improved size table signs were developed. And they were evaluated by the consumers in terms of preferences and awareness of them. Eventually, the best size table sign was selected. From this result, if the large-discount mart use the best improved size table sign on behalf of the current one, the problems of existing size table sign will overcome and improve customer satisfaction.

본 연구의 목적은 CR과 DR에서 가열장치를 구비한 부착형 탄소발열체 X선 촬영대의 사용에 따른 SNR과 CNR을 측정하여 부착 전과 부착 후의 화질을 평가하고자 한다. 알루미늄 계단 실험에서 CR은 부착 후에 SNR과 CNR이 증가하였지만 DR에서는 SNR과 CNR이 감소하였다. 인체모형팬텀 실험에서는 CR의 경우에 저에너지 저선량과 고에너지 고선량에서만 SNR과 CNR이 증가하였지만 다른 모든 조건에서는 SNR과 CNR이 감소하였다. 결론적으로 환자에게 온화한 느낌과 안전감을 제공하고 심적인 불안감을 해소하여 검사에 도움을 줄 수 있지만 임상적용에 있어서는 탄소발열체를 포함한 바닥필름과 보호필름의 두께와 재질을 고려하지 않으면 화질에 영향이 주기 때문에 향후 지속적인 연구가 필요하다고 사료된다.

Purpose: Although use of a tilt table is recommended in clinical practice, there are no published guidelines regarding pressure and inclination for tilt table use. The aim of the current study was to assess the changes of pressure on sacrum and buttock according to different inclination of the tilt table in healthy subjects. Methods: Thirty two healthy subjects participated in this study. Subjects were positioned supine on the tilt table and safety straps were secured across the chest, pelvic, and knee with sufficient tension to prevent the subjects from falling. Pressure and peak pressure of sacrum and buttock were measured using pressure mapping system with the tilt table standing at $0^{\circ}$, $15^{\circ}$, $30^{\circ}$, $45^{\circ}$, $60^{\circ}$, $75^{\circ}$, and $85^{\circ}$ inclination. Results: A significant decrease in the pressure of sacrum and buttock was achieved by increasing tilt table inclination (p<0.05): $0^{\circ}{\sim}15^{\circ}$ (8.16%), $15^{\circ}{\sim}30^{\circ}$ (8.02%), $30^{\circ}{\sim}45^{\circ}$ (11.61%), $45^{\circ}{\sim}60^{\circ}$ (16.18%), $60^{\circ}{\sim}75^{\circ}$ (16%), and $75^{\circ}{\sim}85^{\circ}$ (11.48%). A significant decrease in the peak pressure was achieved by increasing tilt table inclination (p<0.05): $30^{\circ}{\sim}45^{\circ}$ (9.91%), $45^{\circ}{\sim}60^{\circ}$ (19.24%), $60^{\circ}{\sim}75^{\circ}$ (19.93%), and $75^{\circ}{\sim}85^{\circ}$ (11.48%). No significant peak pressure change was observed in $0^{\circ}{\sim}15^{\circ}$, $15^{\circ}{\sim}30^{\circ}$ tilt table inclination (p>0.05). Conclusion: The results of this study showed that the pressure of sacrum and buttock were decreased according to increasing tilt table inclination in healthy subjects. Guidelines are needed in order to optimize patient safety and overall outcome for tilt table standing.

The purpose of this study is to obtain basic materials to complement the 'time series table serving' by analyzing external color elements. We selected traditional Korean restaurants in two five-star hotels and two famous traditional Korean style restaurants and analyzed their colors and the coloration of the Korean table settings. The results are as follows. By using strong luminosity contrast, restaurant A made its customer focus on the food and used red as the principal point (highlighted) color. Desserts, which have small dimensions, were served in 'Buncheong' ware with 'bakji' method, which has strong contrast; this broke the color balance. The use of small patterned dishes with 'johwa' method would achieve color harmony. Restaurant B used a stronger color for the tables than the foods, making the point color inconspicuous. Lowering the brightness and saturation of the table color would be beneficial. In restaurant C, thick green napkins provided the point color, making the atmosphere of the restaurant dull and dark and interfering with the overall bright atmosphere of the restaurant. Using lower saturation, high luminosity, and yellowish colors would bring harmony to the overall atmosphere. In restaurant D, the point colors were divided into three groups; their diversification during the entire course of the meal made the flow of the meal more natural. However, the use of the violet color, which gives a cold feeling, in the middle of the meal courses broke the overall flow of warm color in the meal. Considering the already-present contrast between red and green, it would be better not to use the violet chrysanthemum in the course of the meal. As mentioned above, there are several issues in terms of the color arrangement, the usage of table pads, and the natural flow of colors. Those issues indicate the necessity for an overall plan for the banquet table set-up in terms of color.

Furniture should change according to space. Therefore, it is important that the flexibility of the furniture, the functional efficiency, the economical efficiency and the convenience of the furniture of today. These characteristics are also important for seminar tables that are used temporarily by a large number of people. The seminar furniture currently in use has no shielding plate, there are two forms of table and shielding plate folding table. Therefore, in this research, furniture design and product development that can complement the shortcomings of the seminar furniture currently in use were done. Analysis of problems through overseas investigation and domestic market research, design planning and design, and prototyping. We have sought to optimize the volume by applying the characteristics of RTA furniture to develop a lightweight, lightweight, lightweight, easy to install and easy to use shielding plate, and open and closed system. Basically developed two types of shielding board seminar table basic shape and Roll Screen type, we expanded the scope of application such as each color and pattern. In order to reduce the weight, we replaced the parts such as anchor bolts and hinges and the shielding plate with Roll Screen and pursued volume optimization. As a result of this research, it is expected that the system of mechanisms such as packaging standardization and damage prevention for weight reduction and volume optimization will contribute to building competitiveness by domestic office prefabricated furniture industry's original technology.

Dongrae is one of the most famous hot spring resort area in the Republic of Korea. The water temperature ranges $50^{\circ}C{\sim}66$. The chemical composition of the thermal water is quite different from normal groundwater. $Na^+$ and $Cl^-$ are the main components, measured more than 75%, $Ca^{+{+}}$ is contained about 22% and the other ions such as $SO_4$ or $HCO_3$ are the minor components. The heat source is uprising along the fracture zone of granite which is indicated as a subsurface high temperature belt. During the research period of 1991~1992, the groundwater table was lowered down to the depth of about 100 m according to continuous increase of daily use of thermal water. The groundwater table was fluctuated with an amplitude of day, weak or seasion. The groundwater table was the lowest at 18:00 h in a day and also lowest at the weekend for the week period. There was a relavent relationship between drawdown and the amount of thermal water use on a long term base. To protect such a rapid drawdown of groundwater table, Dongrae resort area is now asked to take strong municipal control for the daily use of thermal water.

Newspaper reader mobile applications using text-to-speech (TTS) function enable blind people to read newspaper contents. But, tables cannot be easily read by the reader program because most of the tables are stored as images in the contents. Even though we try to use OCR (Optical character reader) programs to recognize letters from the table images, it cannot be simply applied to the table reading function because the table structure is unknown to the readers. Therefore, identification of exact location of each table cell that contains the text of the table is required beforehand. In this paper, we propose an efficient image processing algorithm to recognize all the cells in tables by identifying columns and rows in table images. From the cell location data provided by the table column and row identification algorithm, we can generate table structure information and table reading scenarios. Our experimental results with table images found commonly in newspapers show that our cell identification approach has 100% accuracy for simple black and white table images and about 99.7% accuracy for colored and complicated tables.

We study the problem of nonignorable nonresponse in a two-way contingency table and there may be one or two missing categories. We describe a nonignorable nonresponse model for the analysis of two-way categorical table. One approach to analyze these data is to construct several tables (one complete and the others incomplete). There are nonidentifiable parameters in incomplete tables. We describe a hierarchical Bayesian model to analyze two-way categorical data. We use a nonignorable nonresponse model with Bayesian uncertainty analysis by placing priors in nonidentifiable parameters instead of a sensitivity analysis for nonidentifiable parameters. To reduce the effects of nonidentifiable parameters, we project the parameters to a lower dimensional space and we allow the reduced set of parameters to share a common distribution. We use the griddy Gibbs sampler to fit our models and compute DIC and BPP for model diagnostics. We illustrate our method using data from NHANES III data to obtain the finite population proportions.
