Several indices have been developed that use bleeding and color changes as indicators of early gingival pathology. In the presence of gingivitis, vascular proliferation and reduction of keratinization owing to increase redness in gingiva. Descriptions of healthy gingiva are numerous, ranging from pale pink and coral pink to deep red and violet. This terms are not objective. Because of perception of color depends on a lot of factors such as light source, object, observer and so on. It is difficult to make an objective expression. Therefore the using of mechanical equipment is recommended to exclude these variables and observer's vias. The purpose of this study was to evaluate gingival color change after scaling & subgingival root planing. The other purpose of this study was to research the correlation of pocket depth, P.B.I. score and gingival color change. After photo-taking and storaging the image of gingival color into a computer, color change was examine with an image analysis program. Results were as follow; 1. Color of healed gingiva after scaling & subgingival root planing was significantly differ from color of inflamed gingiva(p<0.01). 2. Color of healed gingiva after scaling was similar to color of healed gingiva after subgingival root planing(p<0.05). 3. There was statistically significant correlation between color change of red component and pocket depth after scaling & subgingival root planing(p<0.01). 4. There was no correlation between color change of green, blue component and pocket depth after scaling & subgingival root planing(p<0.01). 5. There was statistically significant correlation between between color change of red component and P.B.I. score after scaling & subgingival root planing(p<0.01). 6. There was no correlation between color changes of green, blue component and P.B.I. score after scaling & subgingival root planing(p<0.01). 7. Increase of pocket depth and P.B.I. score were significantly correlated to the amount of color change(p<0.01). 8. P.B.I. score had a higher correlation with color change than pocket depth(p<0.01).

The purpose of this study was to investigate color planning method for apparel fashion de-sign and to present the method of analysis of green color. Theoretical backgrouds of color planning for fashion design were scrutinized by documentary studies Fashion color planning has been developed through 4 steps: analysis of color environment analysis of color psy-chology presentation of coordination appli-cation to fashion design. Green color environment consisted of mar-ket informations and forecast informations The former were collected by color samples which were used for women's apparel of national brands from '93 spring/summer to '96 spring/summer and the latter were analyzed by fashion forecasting books. Green color psy-chology was investigated through the docu-mentary studiess. image of green color and these expressed in fashion were revealed through documentary studies. The results of this study were as follow: 1. 117 green color samples were collected from domestic womens brand. The character-istic of samples were the yellow green in hue and pale light bright in tone. forecast infor-mation was collected through fashion forecasting books from abroad and adaption of forecast information was investigated by mak-ing a comparison forecasting information be-tween market information. In consequence national market colors reflected the forecast information in concurrence with the character-istic colors of national women's apparel. 2. Affirmative images of green were nature youth health and abundance and negative images were extraordinary misfortune wind-fall. in these images nature youth and health were mostly used in fashion.

The subway lines have been expanded to solve the traffic problems in Korean cities, so that a big number of people daily use the subway stations. Therefore, subway stations became a kind of public space as well as traffic space. However, the underground space of the stations are essentially different with the aboveground space in terms of environmental and psychological terms. The color planning can be used to reduce the environmental and psychological disadvantages of underground spaces of subway stations. The purpose of this study is to understand the current design methods of subway stations' color planning. To achieve this purpose, this study investigates all reports of 'Color Planning for the Subway' which were used for the construction of subway lines in 6(six) Korean cities. After analyzing the design theories and methods used for the color planning, field studies have been done upon 10 subway lines of 6 cities, to find out the limitations of color planning, the differences between color planning and actual results. The conclusions are as follows : First, the color planning for subway stations does not seem to consider the characteristics of underground space and its psychological effects, such as the depth of station, the lighting source and methods. Second, some critical differences have been found between the color planning and the actual application during construction, due to arbitrary interpretation and limitations of color expression of the construction materials. Third, and therefore, the colors applied in stations do not perform their planned role such as 'variety in the unity', 'symbolic expression of the city and station'.

So far, for pearl culture using abalones, a plastic nucleus has been planted in an abalone by perforating the shell. But after planing 80 % of abalones died, and even if they live, the pearl's hardness was not so good. The weak hardness made the pearl valueless. The quality of a pearl is decided by the gloss and the quality of the pearl's layer. This study is to find the right nucleus for abalones and to decrease a death rate of abalones by selecting the right planting place. This study was also performed to obtain valuable pearls with proper size, gloss, and good color. Below is the result of the research; Conch shells out of the various nucleus materials were the best. Their shape, color and gloss were very good. The nucleus was planted in the part that a shell is grown up under the absorption ball, as a result a pearl sack was quickly made. After 15 days, out of every pearl, pearl sacks were made. The pearl formation was measured every month. From the abalone shell which was planted in April, qualitative pearls which was from 5mm to 5.81mm in size were obtained in December.
