Flowery Knotweed Root is the dried tuberous root of the knotweed family wheres Auriculate Swallowwort Root is the dried tuberous root of the swallowort family. Flowery Knotweed Root is also called Red Flowery Knotweed Root in China, which is dried root of Polygonum multiflorum THUMB. Chinese Flowery Knotweed Root is better known as the dried tuberous root belonging to the family Apocynaceae whereas White Flowery Knotweed Root in Korea is the dried tuberous root of Cynanchum wilfordii(Maxim) Hemsl. Up to now, while the dried root named Red Flowery Knotweed Root has been widely used in China, Auriculate Swallowwort Root has been widely used in Korea. Both the roots contrast in a striking way with the origin, shape, botanical names, other names, and chemical constituents, so administration and dosage without discrimination of both sides can be open to question. According to the literature, it is recorded that Flowery Knotweed Root and Auriculate Swallowwort Root are similar to the characteristics, properties, and actions. From this study, the result is as follows: 1. Flowery Knotweed Root and Auriculate Swallowwort Root are divided into the family Apocynaceae and the family Polygonaceae, respectively. Accordingly 2. Flowery Knotweed Root is in shape of an irregular spindle and looks reddish- brown or deep reddish-brown and the section is light yellowish-brown, while Auriculate Swallowwort Root looks yellowish-brown and the section is white or yellow. 3. Flowery Knotweed Root is reported by the Journal of the Crude Drug that the medicinals have not the same therapeutic action as Auriculate Swallowwort Root. It is recorded that the properties, channel entry, functions of Flowery Knotweed Root and Auriculate Swallowwort Root in literature have much in common. Many works on the roots of this plant has been used traditionally as a tonic are required of. In view of the results, Flowery Knotweed Root and Auriculate Swallowwort Root varies both in nature and in shape, so that the administration and dosage of the medicinals must be taken a prudent attitude.

The antioxidant enzyme and DPPH radical scavenging activity with variations in drying methods of diploid and tetraploid in Platycodon grandiflorum were determined. Antioxidant enzyme activities were measured as superoxide dismutase (SOD), catalase (CAT), peroxidase (POX), and ascorbate peroxidase (APX). The roots of Platycodon grandiflorum were freeze-dried, indoor-dried, hot-air dried, and microwave dried. The root extract of P. grandiflorum have shown the highest SOD enzyme activity of 92% in tetraploid of freeze-dried and indoor-dried while diploid of microwave dried showed the lowest SOD enzyme activity of 47.5%. The activity of CAT showed higher values in the root of tetraploid than in the diploid of P. grandiflorum in all drying methods. The APX activity showed relatively higher values in the root extract of freeze-dried both the diploid and tetraploid, but the difference in comparison with other extracts was not significant. The POX activities according to drying methods of diploid and tetraploid in P. grandiflorum showed relatively high values in freeze-dried and indoor-dried compared with other drying methods, and the POX activity between the diploid and tetraploid was not significant difference in each drying method. The DPPH radical scavenging activity with variation in drying methods of diploid and tetraploid in P. grandiflorum was the highest in the freeze-dried, and was higher in tetraploid than diploid in all the concentrations. In conclusion, the root of P. grandiflorum had the potent biological activities in both diploid and tetraploid. In particular, the tetraploid root of P. grandiflorum showing high antioxidant enzyme activity could be good materials for development of source of functional healthy food.

This study was conducted to investigate distribution of free sugas in the ginseng plant and change of free sugar content in dried ginseng with various drying conditions. The results obtained are as follows: 1. The total free sugar content is about 1% in the root and about 2% in the upland portions. Sucrose which accounts 80% in those free sugars, is 0.91% in main body 0.90% in raw ginseng, 0.74% in latheral root, 0.67% in head, 0.57% in skin, 0.64% in leaves, and 0.35% in steins. 2. Sucrose content is 3.3~4.6% in the ginseng root dried at temperature of 3$0^{\circ}C$ and 0.5 ~ 1% in the root dried it at temperature of 50-9$0^{\circ}C$. 3. Maltose was not present in fresh ginseng or dried ginseng which was dried under the t, but it was produced dried at the temperature above 5$0^{\circ}C$, it was 0.5% at 5$0^{\circ}C$, 1.49 %. at 7$0^{\circ}C$, and 4.03% at 9$0^{\circ}C$, respectively. This sugar Height be produced by endogenous saccharifying enzymes.

We explore each of the three major domestic fishery product markets in South Korea- Frozen Squid, Frozen Hair tail and Dried Anchovy- to assess whether we can find evidence for Law of One Price (LOP) across the five major cities- Seoul, Dae-Jeon, Dae-Gu, Gwang-Ju and Busan. To achieve our aim, we utilize two different types of unit root tests: Augmented Dickey-Fuller (ADF) and Kwiatkowski-Phillips-Schmidt-Shin (KPSS) unit root test. In each of the three fishery product markets, we find evidence in support of LOP among several cities, which confirms that these markets are integrated to a certain extent. In particular, we find stronger evidence of LOP for Dried Anchovy market relative to the other two fishery product markets. Based on our findings, we argue that the Dried Anchovy market exhibits a greater degree of market integration across the five major cities in South Korea compared to the other two fishery product markets. The greater degree of market integration in the Dry Anchovy market is facilitated by its higher substitutability across cities; taken together these findings show that the market for Dried Anchovy in South Korea is more efficient than the markets for Frozen Squid and Frozen Hair tail.

In vitro antioxidative activities and antioxidants of the lotus root, dried laver, and perilla leaf bugak, Korean traditional fried cuisine, were evaluated. The bugak was prepared with fermented glutinous rice batter and unroasted sesame oil for use in the pan-frying. The perilla leaf bugak showed the highest radical scavenging activity and reducing power, with the lowest in the lotus root bugak. The antioxidative activity of the blanched lotus root was lower than the dried laver or the perilla leaf. Polyphenol content was higher in the perilla leaf bugak than the lotus root or the dried laver bugak, and tocopherols were mainly derived from frying oil. The antioxidative activity of bugak was correlated well with polyphenol contents, but there was no correlation between tocopherol contents and the antioxidative activity.

Recently, the green roofs market is active, but most constructors use former waterproofing method. So there are a lot of problems in the sub-organization of the green roofs system. I studied to use the block panel for the sub-organization of the green roofs system and I tested about the effectiveness of waterproofing, root barrier, drainage, and insulation. I have not found any problems about waterproofing, root barrier, drainage, and insulation in the results. The sub-organization of the green roofs system using the block panel is effective for waterproofing, root barrier, drainage, and insulation. We can apply it to the dried and unified execution technology.

This experiment was conducted to study the effect of organic fertilizer on the growth of Peucedanum japonicum Thunberg and the change of soil chemical characteristics. The organic matter contents of coffee sludge and dried food waste powder were 44.26 and 51.18%, respectively. These values exceed the organic matter content of organic fertilizers recommended by the Rural Development Administration (RDA) of South Korea by more than 30%. Accordingly, they indicate the possibility of their use as organic fertilizers. The results from the analysis of soil properties after cultivation showed that the organic matter content of coffee sludge amended soils was two-fold higher than that of dried food waste powder amended soils. However, the content of available phosphorus was two times lower in the coffee sludge amendments. It is expected that the dried food waste powder was actively used to decompose organic substances, and that phosphoric acid was added by the soil microorganisms used to decompose organic substances. In terms of Peucedanum japonicum Thunberg growth, leaf discoloration was observed for all treatments except with the standard rate of dried food waste powder. The standard rate of dried food waste powder also produced relatively better results than other treatments with regard to other growth characteristics such as root length (34.08 cm), root diameter (0.78 cm), and fresh root weight (4.77 g plant^-1). Therefore, the standard rate of dried food waste powder produced better results than other treatments and can be used as an organic fertilizer in the growth of Peucedanum japonicum Thunberg.

In this study, cold crack susceptibility of high strength steel (ABS EH32 Steel) welded zone with shielded metal are welding was investigated by tensile restraint cracking test method. Effects of diffusible hydrogen content on root cracking, lower critical stress, crack initiation and fracture mode, hardness value distribution of welded zone and fractograph were mainly investigated. Following conclusions are made: 1. In the view of the lower critical stress level, wet electrode, containing much diffusible hydrogen content shows lower value than dried electrode. 2. Hardness value(Hv 5kg) in Heat Affected Zone of wet electrode is higher than that of dried electrode caused by hydrogen embrittlement. 3. In the case of wet electrode, root crack is initiated and propagated in Heat Affected Zone and then propagated to weld metal, but using of dried electrode, root crack is initiated in Heat Affected Zone and propagated to weld metal without propagating in HAZ. 4. For wet electrode, quasi-cleavage fracture mode is majorly observed on the fracture surface of HAZ and partially of weld metal due to hydrogen embrittlement.

The contents of some chemical constituents in several parts of Panax ginseng were investigated. Each part of ginseng was extracted with 70% ethanol and then water. The yield of extract was the highest in fine root, and relatively low in roughly dried ginseng and white ginseng, On the other hand, the contents of total sugars in white ginseng and seedling ginseng were high, but low in leaf and peel. The contents of crude protein in roughly dried ginseng and white ginseng were high, but those in leaf, rhizome (nod) and peel were low. The content of crude fat was higher in leaf than in other parts of ginseng plants and that was the lowest in fine root. Among free sugars, the content of fructose was high in leaf and rhizome, but that was the lowest in fine root. In the case of glucose content, leaf contained the highest amount, but fine root did the lowest. Sucrose contents in white, roughly dried and lateral roots were high, whereas that in leaf was low.
