The present paper described the relationship between dental anxiety and main colors of elementary student's drawing of dentists. This paper is based on the survey with 555 samples were chosen from a first, second and third grade students of the elementary school located in Chilgok-gun Gyeongsangbuk-do. During the survey, students were asked to picture a dentist by using 12 colors crayon randomly. And the survey result was summarized in three categories. Those are the main color(most frequently used color) distribution in the children's drawings, ratio differences of the main color in terms of gender and the anxiety score for the each color. 1. The order of main colors was blue, white, green, gray, yellow, purple, ocher yellow, orange, pink, red, black and brown from the top to bottom. 2. The main colors distribution in terms of gender, male mostly used green and black compare to female, and female mostly used pink, yellow and white compare to male(p<0.01). 3. The order of the anxiety score for main colors is black, brown, red, yellow, pink, orange, green, white, gray, blue, purple and ocher yellow form the top to bottom(p<0.01).

Mungbean(Vigna radiata (L.) R. Wilczek) is one of legume cultivated in south and east Asia. It well cultivated in high temperature and drought condition. In order to establish pure line for genomic studies, the agronomical characteristics of Korean mungbean landraces were evaluated. A total of 324 acessions derived from National Agrobiodiversity Center were selfed two times in 2021 nersery. Tree times of selfed from 324 accessions were characterized. The color of seed coat was divided into three groups: green, yellow and brown. Among them green color was the most common with 91.7%. Flower colors were divided into four groups: yellow, purplish yellow, greenish yellow and purplish green. Among them purplish yellow color had the highest with 77.8%. Out of 324 resources, only 4 showed compound leaves, and all resources had a heart-shaped leaf. The days to first flowering was 31 to 78 days. About 63% of the accessions bloomed 35 to 50 days after sowing. 324 Korean landraces are expected to be used as a population of the Korean mungbean core collection and serve as a basis for genomic breeding materials for mungbean.

In this study, soybean pods of 45 soybean landraces (or varieties) were classified as yellow (19 samples), black (23 samples), or black in green (3 samples) based on soybean seed coat color. Total polyphenol and flavonoid contents were measured, and antioxidant, anti-inflammatory, anti-obesity, and estrogen-like activities were assessed. Total polyphenol and flavonoid content ranges were 24.13-108.03 mg GAE/g and 3.31-72.02 mg CE/g, respectively, and were highest in the black group followed by the yellow group and were least in the black in green group, while ABTS and DPPH activities followed the order black in green > black > yellow. Estrogen-like and estrogen receptor-α activity ranges were 29.06-35.58 pg/mL and 7.05-10.13 pg/mL and were followed the order yellow > black > black in green and black in green > yellow > black, respectively. Nitric oxide (NO) inhibitory and UCP-1 activities followed the same order as estrogen receptor-α activities. Our findings suggest that soybean pods are excellent sources of antioxidants and high-quality functional materials.

The yellow crystalline material present in yellow and green glass beads excavated from sites in the Baekje region of Korea was previously analyzed through scanning electron microscopy with energy dispersive spectroscopy and X-ray diffraction, revealing that the yellow crystalline material was $PbSnO_3$. This material is a pigment that is rarely seen in the Korean peninsula. Furthermore, some studies have been published on the provenance of lead in this material, which revealed no relationship to Korea, China, or Japan. In this study, we collected all accessible results of analyses on the lead isotope ratio of yellow and green glass beads excavated from the Korean peninsula, specifically from 7 sites in the Baekje region(located in the vicinity of Seoul, Wanju, Hwaseong, Osan, Gongju, Buyeo, and Iksan) and 2 sites in the Silla region(located in the vicinity of Gyeongju and Changnyeong). We subsequently investigated the lead provenance of the opacifying agents in the glass beads through comparison with the current extent of the galena data accumulated for the East Asian region, including Korea, China, and Japan, and for Thailand(Kanchanaburi Province), Southeast Asia. Our analysis determined that the lead provenance of the glass beads excavated from the Korean peninsula was Thailand(Kanchanaburi Province). Beyond our results, further studies should seek to determine the production sites of the glass beads. Obtaining and comparing the scientific analyses of glass beads from India and Southeast Asia would enable research on the glass beads trade through the maritime silk road.

In spite of their inferior quality, pale yellow flue-cured tobacco varieties (N. tabacum L.) are being cultivated as pre-crop of rice in paddy field because of its early leaf maturity. Fertile and male sterile Hicks as green variety , three pale yellow varieties and six single cross $F_1$ hybrids between green and pale yellow varieties, were evaluated. Fertile $F_1$ hybrids were similar to pale yellow varieties in early leaf maturity, curing characters and nicotine contents, where-as they were lower in total nitrogen, higher in reducing sugar comparing to those of the pale yellow varieties.

청경종 특성을 알기위하여 지상부 제형질, 광합성과 호흡 그리고 자식세대의 경색을 조사하였다. 청경종은 엽경종, 황열종의 경, 엽, 광합성과 호흡에 뚜렷한 차이가 나타나지 않았지만 5년근시 화경장 형질이 타 변종보다 길었다. 광합성에 있어서는 청경종이 뚜렷한 차이는 없는 경향이며 비교적 황열종이 높았으나 $20^{\circ}C$ 이상에서는 모든 변종에서 현저히 떨어지는 경향이었다. 청경종내 자식세대 일부는 경색이 분리되는 경향이나 자식사대가 거듭할수록 녹색경(청경종) 출현이 높았다.

Green tides occur every year in the Yellow Sea (YS), and numerous investigations are proceeding on various aspects of the phenomenon. We have identified bloom-forming species collected from diverse locations in the YS using morphological traits and the chloroplast gene for the large subunit of ribulose-1,5-bisphosphate carboxylase (rbcL). Morphological and rbcL sequence data analyses characterized the blooming species on both sides of the YS as belonging to the Ulva linza-procera-prolifera (LPP) complex clade or U. prolifera of earlier reports. However, U. procera within the LPP complex must be regarded as synonym of U. linza. Moreover, U. prolifera in free-floating samples collected from the Qingdao coast in 2009 was clearly in a distinct clade from that of the blooming species. Therefore, U. linza is the main green tide alga in the YS and has the procera-morphology. The green drift mats in the southeastern part of the YS (southwest sea of Korea) consisted predominantly of U. linza and rarely of U. compressa or U. prolifera.

From the evaluation of physical properties such as springiness, gumminess, adhesiveness, chewiness and hardness by the texture analyzer, vegetable soybean lines with green seed-coat were best as compared with those with black, brown, mixed, and yellow seed-coats. A panel test evaluated on the basis of taste, sweetness, chewiness, and total scores also indicated that soybean lines with green seed-coat were the best. The total scores of panel test was decreased in the order of green > yellow> black> brown seed-coat colored soybean. The mean value of sucrose content obtained by HPLC analysis was highest in black seed-coat colored soybean, and followed by green, yellow, and brown soybeans. The highest sucrose content (8.22%) was observed in 180362, a soybean line with green seed-coat. The full-season type soybeans showed much higher sucrose content than summer types which are mainly cultivated on farmer's fields for vegetable purposes. The final 13 lines selected from 300 colored soybeans showed nearly the same panel scores as Miwongreen. However, these lines had a great deal of variation in sucrose content, and much higher readings in texture analysis than Miwongreen, especially in chewiness and hardness which were the most important properties in vegetable soybeans.

Green tides that developed along the coast of China in 2015 were detected and tracked using vegetation indices from GOCI and Landsat images. Green tides first appeared near the Jiangsu Province on May 14 before increasing in size and number and moving northward to the Shandong Peninsula in mid-June. Typhoon Cham-hom passed through the Yellow Sea on July 12, significantly decreasing the algal population. An algae patch moved east toward Korea and on June 18 and July 4, several masses were found between the southwestern shores of Korea and Jeju Island. The floating masses found in Korean waters were concentrated at the boundary of the open sea and the Jindo cold pool, a phenomenon also observed at the boundary of coastal and offshore waters in China. Sea surface temperatures, derived from NOAA SST data, were found to play a role in generation of the green tides.
