Gonadal development, gametogenesis, reproductive cycle, and first sexual maturity of Reishia clavigera were investigated monthly from July 1998 to June 1999 through cytological and histological observations. R. clavigera had separate sexes, and was an internal fertilizer. The ma1e penis was located near the two tentacles. The ovary and testis were composed of a great number of oogenic lobules and spermatogenic tubules, respectively. The size of ripe oocyte ranged from 130 to 140 ${\mu}$m in diameter. The peripheral cytoplasm of the germinal vesicle of the ripe oocyte in many cases were surrounded by smaller yolk granules, while the eccentric cytoplasm was occupied with larger ones. The reproductive cycle of R. clavigera could be classified into five successive stages: early active, late active, ripe, spawning, and recovery. Spawning of females occurred from early July to August when the seawater reached above 24.8$^{\circ}C$. Spawning of males occurred from early June to August in the water above 22.8$^{\circ}C$. Minimum size for sexual maturity of both sexes was above 10.0 mm in shell height. Each egg capsule was a cylinder or spindle in shape, 4-6 mm in length and 1-2 mm in width. Colors of newly spawned egg capsules showed yellowish white or pale yellow, while those with veliger larvae showed pale black, and released larvae or dead egg capsules showed black violet. The fecundity in an egg capsule ranged from 70 to 91 eggs (mean＝80.28 eggs).

The objectives of this study were to investigate the effect of perceiver's fashion involvement, clothing color, and background of object person on image perceptions of clothing, and to examine how clothing color preference vary according to perceiver's fashion involvement. Subjects were 273 college women in the metropolitan area of Seoul. The T-shirt was changed into 11 colors by using the CAD system. Five factors were derived to account for the dimensions of image perception. These were individuality, elegance, femininity, activity, and neatness. Perceiver's fashion involvement gave a significant influence on perception of individuality. Clothing color gave significant influences on 5 image dimensions. White and beige were evaluated neat image. Neatness factor had an interaction effect by fashion involvement and clothing color. The high involvement group evaluated white and beige shirt more neatly, and orange and yellow less neatly than the low involvement group. Individuality and elegance had an interaction effect by fashion involvement and background of object person. The high involvement group liked red, violet, and black shirt more than the low involvement. Refined and becomingness image gave significant influences on clothing color preference in both high and low involvement groups.

This study attempted to develop a representative mild Korean food, including kimchi, bulgogi, galbi, and bibimbap, while maintaining existing images in order to spread Korean food worldwide. Tangpyeongchae is a mild healthy food with a nutritional balance of carbohydrates from cheongpomuk, protein from beef and eggs, and vitamins and minerals from water parsley, bean sprout, and laver. The food has a history of being favored by the political elite of the Joseon Dynasty and has features in Korean storytelling. Tangpyeongchae is an obangsaek food (five representative colors of Oriental philosophy). This study examined modern recipes of Tangpyeongchae in order to establish a standardized cooking method. Furthermore, the study examined customer interest and marketability of natural pigments to develop obangsaek cheongpomuk (mungbean gel) by adding black sesame, a traditional ingredient in Korea, to the cheongpomuk as well as traditional Korean pigments, chija and omija.

Each season, many clothing companies dump small pieces of fabrics left over from making samples. Since fabrics do not decompose easily, this results in environmental pollution. This research was done to discover effective ways to reuse these fabric remnants. As most of these remnants were not large enough for making clothes, fashion accessories was chosen as the design object. Four steps of design development process followed: information research & analysis, prototype design & sample making, market testing, final design decision. After market research and trend analysis, four neck decoration wear -- scarf & muffler(SM). collar & cape(CC), vest & top(VT), and necklace(NE) -- were selected as final product types. 45 designs arose, and 120 items with variations in fabric materials and colors were produced as samples. The three main themes (multiple. reversible, cross) were applied throughout all of the design items. Samples were evaluated from the reactions of the consumers through a 10-day sale at a retail store. Based on the sales record and customers' opinions, five designs from each of the product types SM, CC, and VT were picked out as final designs. In conclusion, fashion accessories turned out to be a more appropriate item to reuse fabric remnants from clothing companies than clothes were, because they necessitate small fabric size and the limitation in fabrics could be compensated with creative design ideas.

The purpose of this study is, as a prior stage to produce manufactured medical goods, to examine literature on the medicinal efficacy of natural dyes that can be used to produce medical goods, and to experiment the possibility of dyeing of some medicinal ingredients that have not been used as natural dyes until now. For this study, 44 types of medicinal ingredients such as Gyomaekchil(buckwheat), Nohoiyeob(aloe), Pogongyounng(dandelion), and Jibooja(broom cypress) were used. First, they were classified by a thermal sensation such as hot, warm, neutral, cool, and cold feeling, and by their characteristics of complex tastes such as sweet, sour, bitter, salty, pungent, astringent, and flat tastes. And then they were dyed with two types of mordant, resulting to a total of 132 types of dyed cloths. The 132 dyed cloths could be classified as five types of colors: 89 types(67.42%) of yellow series, 25 types(18.94%) of yellow-red series, 6 types(4.55%) of green-yellow series, 6 types(4.55%) of purple series, and 6 types(4.55%) of purple-blue series. The results of this study found that there were various medicinal ingredients that had efficacy to cure skin disorders and also could be used as natural dyes.

Due to the inconsiderateness of human capability and inappropriate arrangement of display and control unit at the industrial site, the human error leads to a various accidents. This study was performed to investigate the visual range at the eye field and stationary field at the various angles with three different visual stimuli of alphabetic character, color slip and light-emitting diode. Three kinds of various alphabetic characters depending on length and breadth ratio (1:1, 3:5, 5:3) and three different colors (red, yellow, green) were used for the stimuli. Twenty-five subjects (11 males and 14 females) participated for this study. The results showed that female had wider visual range than male at the eye field, however no significant difference was found at the stationary field. The light-emitting diode had a widest visual range then color slip and characters are in order at the eye field and stationary field. For the character stimulus, the widest visual range was shown at length and breadth ratio of 1:1. The other ratios (3:5 and 5:3) showed no significant difference. The color of red had a widest visual range on the light-emitting diode, however, the color of yellow showed a widest visual range on the just color slip at the eye field. The result of this study would be valuable in applying to the design of visual display and the panel layout of control and displays in the industrial site.

Color is an important factor in dental esthetics. Application of natural tooth color will not fail to produce pleasing results. But a standardized method of shade matching has not been adopted. If we are to overcome the color matching problem in dentistry, an understanding of the nature of color and light is essential. The purpose of this study was to compare the effects of different light sources and different background colors on the ability of observers to correctly match shades of artifical teeth. And observation was made to determine if the time spent in making a shade match was a factor in the correctness of the response. A test method was devised and 50 individuals made observations which were recorded and analyzed. $X^2$-test gave results indicating that the time factor had no effect on the response made. An analysis of variance showed the following effects significant at the five percent level; (1) light source (2) background color (3) subject. The following conclusions can be drawn from this study; (1) The time spent in making shade selection is not a factor in the correctness of the selections. (2) The light source used is an important factor in matching tooth shade; and there is no significant difference between the light sources in shade matching. (3) Under the conditions of this study, the greatest accuracy in shade matching was obtained on the brown background.

We examined the floral morphology of 15 taxa of five genera (Cynanchum, Marsdenia, Metaplexis, Tylophora, and Vincetoxicum) in Korean Asclepiadoideae using a stereoscopic and scanning electronic microscope to clarify and describe the floral characteristics. In this study, the corolla and corona types, the types of corona lobes, appendages on the corona lobes, and the apex shape of the style head are considered as diagnostic characteristics at the generic level. The genus Vincetoxicum, which is treated as a synonym of the genus Cynanchum in Korea, is distinguished from Cynanchum by the interstaminal part on the corona, fleshy and mainly triangular or ellipsoid corona lobes, and various corolla colors. In Cynanchum, various corona types have been observed, while Vincetoxicum have similar corona types among the taxa. In addition, the main floral characteristics at the species level were as follows: flowering time, inflorescence, corolla color, trichomes on the corolla surfaces, apex shape of the corona lobe, and trichomes on the ovary. This study presents the taxonomic importance of floral morphology by providing descriptions and diagnostic characteristics among the genera and species investigated.
