자동차를 사러 매장에 갔을 때 우리는 자동차의 색상에 따른 교통사고의 발생 확률과 무관하게 자동차의 성능이나 디자인과 또는 자동차의 가격이나 안정성 등을 최우선으로 꼽고 자동차를 선택한다. 본 논문에서는 자동차의 색인 파랑, 녹색, 흰색, 빨강, 검정, 황색의 차량을 대상으로 색상별로 사고 내역을 조사하여 사고가 발생할 확률이 가장 높은 색부터 가장 낮은 색까지를 차례로 제시한다. 사고가 많고 적음은 색에서 진출색과 후퇴색의 차이로서, 사고가 많이 나는 색이나 사고 나기 쉬운 색은 실제보다 멀리 있는 것처럼 보이는 후퇴색이고, 사고가 적은 색은 실제보다 더 가까이 있는 것처럼 보이는 진출색임을 알 수 있다.

Vertical distribution of squids in relation to oceanographic structure was analyzed on the basis of experimental squid hand jigging fishing by R/V Pusan 851 in the area of 34°∼47° N, 150° E∼170°W in the North Pacific in summer from 1987 through 1993 with exception of 1991. The 6 species of squids showed different patterns of vertical and horizontal distribution as following; Boreopacific gonate squid (Gonatopsis borealis) were mainly caught in the layer of 71-80m fishing depth of the Subarctic Domain with water temperature of 6∼11℃ and salinity of 32.2∼33.6‰ and distributed in the latitudes of 41°∼43° N. Boreal clubhook squid (Onychoteuthis borealijaponica) were mainly caught in the layer of 11∼20m fishing depth of the Subarctic Domain with water temperature of 10∼12℃ and salinity of 32.9∼33.6‰ and distributed in the latitudes of 41°∼42N°. Tapanese flying squid (Todarodes pacificus) were mainly caught in the layer of 11∼20m fishing depth of the Transition Zone and the Subtropical Domain with water temperature of 15∼18℃ and salinity of 33.6∼34.0‰ and distributed in the latitudes of 40°∼42°N. Neon flying squid (Ommastrephes bartrami) were mainly caught in the layer of surface∼10m fishing depth of the Subarctic Convergence Zone and the Transition Zone with water temperature of 16∼17℃ and salinity of 33.7∼34.4‰ and distributed in the latitudes of 39 °∼41°N. Luminous flying squid (Symplectoteuthis luminosa) were mainly caught in the layer of 11 20m fishing depth of the Transition Zone and the Subtropical Domain with water temperature of 18∼20℃ and salinity of 33.8∼34.6‰ and distributed in the latitudes of 37°∼39°N. Purpleback flying squid (Symplectoteuthis oualaniensis) were mainly caught in the layer of surface∼10m fishing depth of the Subtropical Domain with water temperature of 24∼25℃ and salinity of 34.2∼34.4‰ and distributed in the latitude of 36°∼37°N.

Although much research has focused on various bioactive substances in starfish, research on microorganisms isolated from starfish is lacking as compared with other natural products. In this study, we investigated bacterial communities in the gut of red starfish (Certonardoa semiregularis) in Jeju Island. In total, 103 bacterial strains were isolated using marine agar and R2A medium. The isolated strains were analyzed and identified using the 16S rRNA gene sequence. Based on an analysis of this gene sequence, the 103 isolated bacteria were classified into four major groups: Proteobacteria (93%: Alpha-proteobacteria, 24.8%; Beta-proteobacteria, 4%; Gammaproteobacteria, 65%) Bacteroidetes (4%), Actinobacteria (2%), and Firmicutes (1%). In addition, the isolates were divided into seven classes (Actinobacteria, Flavobacteria, Bacilli, Sphingobacteria, Alphaproteobacteria, Betaproteobacteria, and Gammaproteobacteria), 15 orders, 19 families, and 24 genera. A phylogenetic analysis revealed two strains, Lysobacter sp. and Pedobacter sp., with similarity of 97.55% and 97.58%, respectively. As the similarity in the 16S rRNA gene sequence was 98% or less compared to previously identified bacteria, the two strains may possibly be classified as a new genus or species. We suggest that additional studies, including biochemical and morphological tests, should be performed to identify the new candidate strains.

This research was conducted to see the impact of brightness, polarity, and hue diference on legibility and emotional effcts of the word. In the experiment 1, stimuli with three levels of brightness difference and two-typed polarity were used. The results showed that legibility, aesthetics, and preference increased with increasing brightness difference. In the experiment 2, the same stimuli if experiment 1 included four hues: red, green, blue, yellow. As a result, the effects of brightness and polarity and the interaction effect of brightness and polarity on legibility were significant. Also, the effects of brightness, polarity, and hue and the interaction effect of brightness and hue on aesthetics and preference were significant. These results showed that legibility, aesthetics, and preference increased with increasing brightness difference of word and background and positive polarity was better than negative. Aesthetics and preference rating increased according to the following order: red, blue, green, yellow. In addition, the interaction effect of brightness and polarity on legibility was because reaction time of negative polarity was longer than positive at the small brightness difference condition. The interaction effect of brightness and hue on aesthetics and preference ws because the aesthetics rating of hue at the large brightness difference condition had significant difference compared with small brightness difference. In the experiment 3, participants rated text designs and simple color stimuli with 18 emotional adjectives to see the similarity of their emotion. The conclusion was that to reflect the subjective feelings of a rotor on the text design, it would be appropriate to use the rotor on background of the text design.

The objective of this study is to improve the optical sensitivity of laser fluorescence for detection of incipient enamel caries. An incipient carious lesion was formed in various stages by placing an enamel specimen of a bovine tooth in STPP demineralization solution. After measuring the optical density of the lesion surface by laser fluorescence induced by argon laser and various alter of yellow(500-520nm), amber(520-540nm), orange(540-560nm), and red(560-580nm), the specimen was cut vertically to measure the depth of the lesion using a polarizing microscope. SAS statistical program was used to analyze the relationship between the optical density of the lesion suface and the depth of the lesion. The results were as follows: 1. The optical density of early carious lesion, measured by laser fluorescence with amber and orange filter, and lesion depth observed by polarizing microscope, were increased as demineralization time increased. 2. The correlation coefficient between optical density of the lesion surface and the histological depth of the lesion was the highest in orange filter(r=0.49), followed by amber(r=0.32), yellow(r=0.13) and red(0.01). 3. Regression analysis showed that the most linear relationship between the optical density and the lesion depth was existed in orange filter group. In regard above results, laser fluorescence could be considered to be reliable for optical diagnosis of dental caries.

Purpose: The purpose of this study examined the distribution of constitution(Con) types by examining the Chinese constitution table questionnaire with 594 Seoul citizens. It investigated the preferences of five colors by the Con. It then was to explore the validity of the test and the five colors according to the Con. Methods: We used the CC table questionnaire and surveyed by using a cardinal color. Results: The Con type distributions include yangweak(31.4%), yin-weak, gall-humidity, harmony, qi-weak, qi-gloom, specific, and extravasate in order. The lack of statistical significance also indicates that the CC test is not appropriate for Seoul citizens. The order of five preferences is 31% in blue, 25.3% in yellow, 18% in white, 17.7% in red, and 8% in black. Blue was the most preferred and black the least. There were differences in the distribution of five colors, but they were not statistically significant. In five viscera diseases of the yang-weak con, the stomach was more than half(50.3%). The highest preferred color was blue (30.9%). This difference was significant(p <.01). It evaluated that this influences the preference of five colors by five diseases. Conclusions: The constitution of Seoulian in the CC survey distributed into nine categories. There was a difference in preference of five colors by the con. However, it was not significant. This indicates that the Chinese con table is not suitable for Seoulian. However, the results are to be primary data for research in this field.

Purposes: The purpose of this study was to investigate the relationship between five viscera, environmental and seasonal changes, and their preference for five colors. Methods: The survey performed using the Chinese medicine constitution and the five cardinal colors (Red, Blue, Yellow, White, Black) paper. Results: The blood types distributions were A, O, B, AB, and others in order. The proportion of smokers(75.6%) and non-drinkers(25.6%). Their color preferences were highest in blue and the lowest in black, but not significant. The proportion of the viscera was stomach(45.3%), liver-lung, intestine, and heart, and the tastes were spicy(48.8%), sweet, sour, salty, and bitter in order. Blue was the highest in all. kidneys(8.3%) preferred red and bitter yellow. The change in mind(35.7%) was highest, followed by scary thoughts and their color preferences varied. The most preferred place was 'cold place,' and 'dry place' was low. The most preferred seasons were 'autumn (38.6%), and the lowest was rainy. And their colors preference were blue. The respondents(89.9%) were normal, 5.7% hypertension and 4.4% hypotension. Healthy people preferred blue (91.8%) and hypertensives yellow with not significant. The diabetics preferred blue and red(p<.04). Conclusions: In the questionnaire survey on the health and physical abnormalities of Seoul citizens, various distributions found in each category, and most of them preferred blue. The results indicated that the questionnaire and the five- colored preference were a little interrelated. However, the results are to be primary data for research in this field.
