Rose is one of the most economically important ornamental crops worldwide. Although rose products are widely used, limited genetic and genomic data from this species is available. Fundamental genetic knowledge can accelerate the development of superior rose germplasms. In the present study, we explored the genetic data (e.g., chromosome numbers, total chromosome length, and ploidy level) of 39 rose cultivars using conventional cytogenetic methods. Of the 39 rose cultivars tested, 36 (92.3%) were tetraploid (2n = 4x = 28). ‘Rosada,’ ‘Rosemarin,’ and ‘Hanmaum’ were diploid (2n = 2x = 14), triploid (2n = 3x =21), and tetraploid-based aneuploid (2n = 4x = 28 + 2), respectively. The total chromosome length ranged from 46.03 ± 0.55 μm in ‘Rosada’ (2x) to 138.51 ± 0.92 μm in ‘Christoper’ (4x). The chromosome information obtained in this study will be useful for rose breeding and germplasm evaluation.

In this study, a new method of rapid preparation of carbon nanotube (CNT) solution with highly dispersed morphology by free arc excitation is proposed, which shortens the time of the preparation of CNT solution with low concentration. The principle is that the high-energy flow density heat generated by the free arc makes the vaporizable substance coated on the surface of CNTs vaporize rapidly, and then generates the bulk increasing motion, which makes the CNTs aggregates dispersed, and finally forms the CNTs gas-phase dispersion monomer with high dispersion or the cross-linking morphology of few CNTs. In this paper, the influence of gum Arabic (GA) and deionized water (DI water) contents in CNTs mixed electrode on the dispersion of CNTs in different environments (gas phase and liquid phase) is explored. In the limited case of this work, the dispersion effect is better when the mass ratio of CNTs, GA and DI water is 1:0.04:3.96 in the liquid-phase environment. The preparation method reported in this work is expected to be a rapid way to obtain low-concentration nanodispersion.

To investigate the effect of gas dispersing carbon nanotubes (CNTs) and hot pressing method on the transparency and the conductivity of thin films, the free arc was used to disperse the CNTs in a high dispersion rate, and the dispersed CNTs were rapidly pressed into the surface of the PET film by hot pressing to obtain electrical conductivity. The relationship between the light transmission and sheet resistance of the film was studied by changing the deposition time and the presence or absence of electrostatic adsorption. It was found that the CNTs modified film still retains good electrical conductivity (sheet resistance up to 6 × 104 Ω, light transmittance 69%) through the cleaning of surfactants and ultrasonic waves, which proves that hot pressing is a simple physical method to achieve effective combination of CNTs and films.

Fifth, head belt-type ornaments consist of a headband and fancy bead ornaments from the bottom of the head. Mongol women usually wear an exaggerated form of this type. Sixth, the head cover type is a head decoration influenced by the dress code of Muslim women. Seventh is the disc type of crown shape worn by the Dai. Next, the ogival type is a cone-shaped headdress hat most commonly seen as head ornament hat among the Dai. Lastly, the sailboat type is the most exaggerated form of hair ornaments found among ethnic minorities.

This experiment was conducted to a comparison of the productivity according to variety and forage quality by plant parts of imported silage corn (Zea mays, L) in Pyeongchang. The corns evaluated in this experiment were 8 varieties (P1184, P1151, P1194, P1543, P1345, P1429, P1443, and P2105) introduced from the United States, Pioneer Hybrid Co. The harvested corn was divided into 5 plant parts (leaf, stem, cob, husk, and grain), and the ratio of each part was calculated using dry weight and the feed value was analyzed. The emergence rate of corn was generally good except for the P1151 and P2105 varieties. The average tasseling date was July 24th and the silking date was July 27th, but the P2105 variety was late to July 28th and August 1st, and the remaining varieties were similar. P1345 was the highest (289 and 123 cm), and P1151 varieties were the lowest (267 and 101 cm) in the plant and ear height. Disease resistance was low in P1184, P1443 and P1429, and P1197 and P1345 were high. In the case of stover, the dry matter (DM) content was the lowest at 19.6% in the P1151 and the highest at 24.9% in the P1429. DM content of ear was the highest in the P2105 (55.5%), and P1184 (54.2%) and P1345 (54.3%) were also significantly higher (p<0.05). The DM yield of stover of P2105, P1429 and P1194 varieties was significantly higher (p<0.05), and ear yield of P2105, P1345 and P1443 was higher. The proportions of each part of plants (leaf, stem, cob, husk, and grain) divided by 5 was high, with 50-60% of the ear(grain+cob) ratio. The ratio of husk and cob was roughly similar, and the leaf and stem part showed a ratio of about 20%. The crude protein (CP) content was highest in leaf, followed by grain. The CP content of the stem was the lowest, and the husk was not significantly different among the varieties (p>0.05). The acid detergent fiber (ADF) content was similar to the rest parts except grain, but the leaf part tended to be lower, and other parts except the stem and leaf showed no significant difference between varieties (p>0.05). There was no significant difference in NDF (neutral detergent fiber) content in husk, but there was a difference between varieties in other parts (p<0.05). In addition, there was a special difference by plant parts for each variety, P2015 on the stem, P1197 on the leaf, P1151 on the cob, P1197 on the husk, and P1197 on the grains with high NDF content. IVDMD (in vitro dry matter digestibility) was not significantly different between stems and grains, but there was a difference between varieties in cobs and husks. According to the results, DM yield of P2105 variety was the best in the experiment, and the ratio of grain was excellent in P1543 and P1345. In addition, it was found that the feed value was higher in the leaves and grains, and the leaf and stem had higher feed values than husk or cob.

Carbonaceous materials are considered as potential adsorbents for organic dyes due to their unique structures which provide high aspect ratios, hydrophobic property, large efficient surface area, and easy surface modification. In this work, graphene nanoribbons (GNRs) were prepared by atomic hydrogen-induced treatment of single-walled carbon nanotube (SWCNTs), which inspire the idea of cutting and unzipping the SWCNTs carpets with the modified in molecules prevent because of the unfolding of the side-walls. The unfolded spaces and uniform vertical arrangement not only enhance the active surface area, but also promote the electrostatic and π–π interactions between dyes and GNRs. The improved adsorption capacity of GNRs beyond original SWCNTs can be determined by the adsorption kinetics and isotherm, which are evaluated through adsorption batch experiments of the typical cationic methylene blue (MB) and anionic orange II (OII) dye, respectively. It is shown that the adsorption kinetics follow a pseudo second-order model while the adsorption isotherm could be determined by Langmuir model. The results reveal that the maximum adsorption capacities of GNRs for MB and OII are 280 and 265 mg/g, respectively. The GNRs present the highly efficient, cost effective, and environmental friendly properties for the commercial applications of wastewater treatment.

This study was conducted to compare the agronomic characteristics and productivity according to the species and varieties of winter forage crops in reclaimed land. Winter forage crops used in this study were developed in National Institute of Crop Science, RDA. Oats (‘Samhan’, ‘Jopung’, ‘Taehan’, ‘Dakyung’ and ‘Hi-early’), forage barley (‘Yeongyang’, ‘Yuyeon’, ‘Yujin’, ‘Dacheng’ and ‘Yeonho’), rye (‘Gogu’, ‘Jogreen’ and ‘Daegokgreen’) and triticale (‘Shinyoung’, ‘Saeyoung’, ‘Choyoung’, ‘Sinseong’, ‘Minpung’ and ‘Gwangyoung’) were planted in the reclaimed land of Sihwa district in Hwaseong, Gyeonggi-do in the autumn of 2018 and cultivated using each standard cultivation method, and harvested in May 2019(oat and rye: 8 May, barley and triticale: 20 May.) The emergency rate was the lowest in rye (84.4%), and forage barley, oat and triticale were in similar levels (92.8 to 98.8%). Triticale was the lowest (416 tiller/㎡) and oat was the highest (603 tiller/㎡) in tiller number. Rye was the earliest in the heading date (April 21), triticale was April 26, and oat and forage barley were in early May (May 2 and May 5). The plant height was the highest in rye (95.6 cm), and triticale and forage barley was similar (76.3 and 68.3cm) and oat was the lowest (54.2 cm). Dry matter(DM) content of rye was the highest in the average of 46.04% and the others were similar at 35.09∼37.54%. Productivity was different among species and varieties, with the highest dry matter yield of forage barley (4,344 kg/ha), oat was similar to barley, and rye and triticale were lowest. ‘Dakyoung’ and ‘Hi-early’ were higher in DM yield (4,283 and 5,490 kg/ha), and forage barley were higher in ‘Yeonho’, ‘Yujin’ and ‘Dacheng’ varieties (4,888, 5,433 and 5,582 kg/ha). Crude protein content of oat (6.58%) tended to be the highest, and TDN(total digectible nutrient) content (63.61%) was higher than other varieties. In the RFV(relative feed value), oats averaged 119, while the other three species averaged 92∼ 105. The weight of 1,000 grain was the highest in triticale (43.03 g) and the lowest in rye (31.61 g). In the evaluation of germination rate according to the salt concentration (salinity), the germination rate was maintained at about 80% from 0.2 to 0.4% salinity. The correlation coefficient between germination and salt concentration was high in oat and barley (-0.91 and -0.92) and lowest in rye (-0.66). In conclusion, forage barley and oats showed good productivity in reclaimed land. Adaptability is also different among varieties of forage crops. When growing forage crops in reclaimed land, the selection of highly adaptable species and varieties was recommended.

Tour application have a lot of information to offer. Because smart phones’ screen is small, it is necessary to efficiently organize user interface(UI). To have a quantity analysis on human's' attention affected by layout position in tour application UI design, an experiment was proposed and then the data analysis was done. Thirty subjects took part in our experiment and 20 tour application layout images divided into four area of interest (AOI) were taken as the stimulus randomly. Data was recorded by the Tobi Pro X2-30 eye tracker system. The heat maps and gaze plot results were analyzed. And then One-way ANOVA (analysis of variance) statistical method was applied to finding out the significant difference in factor levels. Results show that the active area and eye movements tracking roads within statistic meaning. Moreover, ANOVA (F = 24.28, p = 2.21267e􎂡15 < 0.01) shows that the different positions have significance difference effect on subjects' attention and mean of AOI (4) is a significant difference from other three area. And then the influence degree of AOI (4) (F = 13.90, p = 0.098 > 0.05) is weaker than other regions through the simple test. In conclusion, the tour applications should be considered the layout position effects on improving the attraction for corresponding users.
