This study developed a practical knitwear design with applying the pattern of Queen Yeong's pearl pouch. The ume flower pattern of pearl pouch was simplified to be one repeat pattern, and four simulated knit pattern samples of G-A, G-B, R-A, and R-Bwere made with cable, cross, and two background colors of gray and red using Texpro V.11.0. The items of design application were selected after an interview with a panel of university students in their twenties and knit samples were produced by hand knitting. The small sized G-A for the partial ornament of hat, sweater, skirt, kitchenware case and accessories; the long sized G-B for the tuck of sleeves, hem of skirt and one-piece dress, partial ornament of sweater, scarf, and curtain decoration: the small sized R-A was preferred for point ornament of pouch, boots, hat, partial ornament of children's fashion products and accessories: the long sized R-B for table runner, leg warmer, tuck of sleeves, skirt hem, necktie, and scarf. The knit samples were formulated with partial ornaments attached on dress and props or connected each other. Colors of pastel and navy were also presented to meet the demands of panels. The study placed a limit on the slight difference between the simulation samples and knit samples due to the characteristics of threads and hand tension. The color variation for multiple coordination and activation to reduce the piece rate for young customers remains to be discussed in the near future.

This study examined the effective utilization of pearl processing by-products. Three extracts of hot-water extract (WE), hydro-cooked extract (HE), and two-step enzymatic hydrolysate (EH) were prepared from pearl oyster muscle, and their characteristics were examined. The moisture, crude protein, volatile basic nitrogen (VBN), and amino-N contents were 97.5-98.0%, 0.5-1.3%, 2.1-4.9 g/100 mL, and 35.0-74.5 g/100 mL, respectively. EH had the lowest VBN and highest amino-N contents. In addition, EH had the highest yields. In terms of its functional properties, EH inhibited angiotensin-I converting enzyme ($IC_{50}$, 1.39 mg/mL) more strongly than the other extracts ($IC_{50}$, 4.17-7.95 mg/mL). The free amino acid contents of WE, HE, and EH were 661, 470 and 1,150 mg/100 mL, respectively. Major amino acids were taurine and glutamic acid. Major inorganic ions were Na, Mg, and Ca. Contents of taste compounds, such as free amino acids, inorganic ions, and quaternary ammonium bases, differed significantly according to the extract methods. Based on the results of chemical experiments and sensory evaluation, the quality of EH was superior to the other extracts, and EH is suitable for use in natural flavoring materials.

This study was to analyze the social identity described in the dress of the American novelist Pearl S. Buck's (1892-1973) major works. A novelist pursues varying and refined expressions in an effort to convey to readers the character' identities of his or her own creation. In particular, Pearl S, Buck was a great writer who was awarded the Novel Literature Prize, and since her work The Good Earth recorded a world-wide bestseller, she might well be called a popular novelist. She depicted well her characters' identities from divers viewpoints with her unique delicacy and realistic expressions. For this study, the following seven works which are considered to feature the dresses for character's identity well were selected out of her 85 works: The Good Earth (1931), Sons(1932), The Mother (1934), A Housed Divided (1935), The Hidden Flower (1952), Love and the Morning Calm (1953) and Letter from Peking (1957). For an analytical tool, the content analysis method was used. In order to systematically review the social identity described in the dress individuals' identity were classified into the following categories based on the identity theories: Social identity were divided into ① age identity ② sex, gender identity ③ economic identity ④ occupational identity ⑤ political identity ⑥ religious identity ⑦ kinship identity ⑧ regional identity. The characters' age identity, sex, gender identity, economic identity, occupational identity, political identity, religious identity, kinship identity, regional identity were depicted by their dresses and physical features. All in all, it is hoped that this study would provided important cues to the understanding of the other party's identity through his or her dresses in mutual relationship: It is believed that this study would be useful because they are arranged through the analysis of the dresses featured in the great writer's works using a consistent framework of analysis.

This experiment was canied out to study -the effects of different seeding date on the yields and nutritional value of Pearl millet. Seeding dates were $S_1$,$S_2$,$S_3$,$S_4$, and $S_5$, and harvest dates were $S_1$, (7 July) and $S_2$, (18Augst), respectively. The results were summarized as follows: 1. Plant length was not influenced by seeding date at each harvest. The seeding date at $S_4$,showed the longest plant length of 90.4 an on average per year, which was longer by 17 cm compared to 73.3 cm harvested at $S_5$. 2. Total dry matter yield was not significantly different among seeding dates. Total dry matter yield in 1993 increased according to delayed seeding date from $S_1$ to $S_4$. Dry matter yield of 17.3 tonha was obtained in $S_4$. 3. The relative yield of leaf tended to increase with delayed seeding date, and varied from 60% to 69%. 4. Dry matter ratio decreased with delayed seeding date from $S_1$,(20 April) to $S_5$ (30 May), and varied from 15.6% to 12.3%. 5. Crude protein content of leaf at 1st and 2nd harvest and stem at 1st harvest were significantly different among various seeding dates. Avenge crude protein content increased with delayed seeding date from 9.0% at $S_1$ (20April) to 12.8% at (30 May) $S_5$ (30 May). 6. NDF and ADF of leaf at the 1st harvested were significantly different among seeding dates. NDF content decreased with delayed seeding date from 61.9% to 57.8%, and ADF content decreased with delayed seeding date from 34.8% to 32.2%.

Experiments were carried out to evaluate the tolerance of trochophores for pearl oyster, Pinctada fucata martensii and Pacific oyster, Crassostrea gigas using different concentrations of cryoprotectants : dimethyl sulfoxide (DMSO), ethylene glycol, glycerol and 1,2-propanediol. Each cryoprotectant with different concentrations was exposed for 5, 10, 15 and 20 minutes of immersion time. Survival rates were increased with decreased concentrations of cryoprotectant and decreased immersion time, and these differed from types of cryoprotectant. Survival rates of Pacific oyster trochophores were higher in DMSO and ethylene glycol, while those of pearl oyster trochophores were higher in glycerol and 1,2-propanediol. In case of trochophores from Pacific oyster, when 0.2 M sucrose was added in each cryoprotectant the survival rates were increased significantly.

It is known that Sung-gyu Jeon and several other Korean artisans were invited to "Joseon-Najeon Company" of Kimura Tenko in Takaoka, Japan to teach the skills of making lacquerware inlaid with mother-of-pearl, however these artisans discovered a new tool called fretsaw during the visit, which can easily cut nacre. The introduction of fretsaw in the 1920s in Korea innovated the Jureumjil(filing) technique and dramatically changed the style of modern Korean lacquerware inlaid with mother-of-pearl. In this paper, I will focus on the case of Sung-gyu Jeon, Kimura Tenko and "Joseon-Najeon Company". I will also examine why and how the Korean lacquerware artisans went to "Joseon-Najeon Company" in Takaoka and exactly what they did there. This analysis will help in discovering how the Korean artisans' experience in Takaoka affected their works after they came back to Korea.

In this paper, we present a nondestructive analysis using X-ray and microscopic investigation to detect the structure, manufacturing technique and preservation status of the Goryeo lacquered box Inlaid with Mother-of-pearl Chrysanthemum and Scroll Design (Goryeo Lacquered Box). We confirm that the Goryeo Lacquered Box consists of the soft wood as the basic material. The soft wood was coated with textile and then lacquered. The box structure of the Goryeo Lacquered Box was formed of wooden boards with wood plants added to the side, after processing into a trefoil-shaped. The wooden sides of the Goryeo Lacquered Box were cut at regular intervals for easier processing into a curved shape. Moter-of-pearl, tortoiseshell, and metal wire were used to decorate the surface. mother-of pearl was the cutting processing, and tortoiseshell was used for back coloring. The metal line was constructed using one line and twist line.

The soil organisms that develop beneficial Symbiotic relationships with plants roots and contribute to plant growth are mycorrhizal (AM) fungi. Arbuscular mycorrhizal inoculations change the growth and biochemical composition of the host plant and soil. Mycorrhizal root systems do augment the absorbing area of roots from 10 to 100 times thereby greatly improving the ability of the plants to utilize the soil resources. A pot experiment was conducted during the kharif seasons at Jaipur, Rajasthan, to find out the effects of three different indigenous AM fungi i.e. Glomus mosseae, Glomus fasciculatum and Gigaspora decipiens either single and in combination inoculation on biochemical and histochemical changes of Pearl millet (Pennisetum glaucum L.) grown under barren soil conditions. The AM fungus has shown to improve the tolerance of plant to drought stress. Experimental results showed that AM fungi treated plants improved their plants growths, biochemical and histochemical changes as compared to non-mycorrhizal treatments. The AM fungi inoculated plant was found to be attaining maximum plant biochemical and histochemical substances in Glomus mosseae (alone) and also Glomus mosseae + Glomus fasciculatum treatments.

Virulence and genetic diversity were studied using 21 isolates of Sclerospora graminicola, the pearl millet downy mildew pathogen collected from major pearl millet growing areas of India. Variability for virulence was determined by inoculating a set of 10 differential hosts with the S. graminicola isolates in a greenhouse. The isolates varied for latent period (6.4 to 11 days), disease incidence (0 to $98\%$), virulence index (0 to 18.7) and oospore-production potential (1 to 4). Among the 21 isolates, Sg 139 (Rajasthan) was the most virulent and Sg 110 (Tamil Nadu) the least virulent. Based on virulence index (disease incidence$\time$slatent $period^{-1}$), the 21 isolates were classified into eight virulence groups. Genetic diversity among isolates was studied using AFLP markers. Based on similarity index of banding pattern, the 21 isolates were clustered into eight genotypic groups. The AFLP groupings, however, did not match with that of the virulence groupings, and these two were found independent. The isolate Sg 139 that remained distinct in both pathogenic and genetic groupings indicated its highly virulent nature. Implications of these results in downy mildew resistance breeding are discussed.

This paper presents a new configuration for a three-phase multilevel voltage source inverter. The main bridge is built from a classical three-phase two-level inverter and three bidirectional switches. A variable DC-link employing two unequal DC voltage supplies and four switches is connected to the main circuit in such a way that the proposed inverter produces four levels in the output voltage waveform. In order to obtain the desired switching gate signals, the fundamental frequency staircase modulation technique is successfully implemented. Furthermore, the proposed structure is extended and compared with other types of multilevel inverter topologies. The comparison shows that the proposed inverter requires a smaller number of power components. For a given number of voltage steps N, the proposed inverter requires N/2 DC voltage supplies and N+12 switches connected with N+7 gate driver circuits, while diode clamped or flying capacitor inverters require N-1 DC voltage supplies and 6(N-1) switches connected with 6(N-1) gate driver circuits. A prototype of the introduced configuration has been manufactured and the obtained simulation and experimental results ensure the feasibility of the proposed topology and the validity of the implemented modulation technique.
