About 70 high redshift quasars with $z{\geq}5$ have been discovered through combinations of standard broad-band filters to distinguish them from contaminating sources. However, among the discovered quasars so far, there is a redshift gap at $5{\leq}z{\leq}6$ due to the limitation of traditional filter sets and selection techniques. To understand the early mass growth of supermassive black holes and the final stage of the cosmic reionization, it is important to find a statistically meaningful sample of quasars with various physical properties. Here we suggest a new selection technique of high redshift quasars using medium-band filters: nine filters with bandwidths of 50nm and central wavelengths from 625 to 1025nm. Photometry with these medium-bands traces the spectral energy distribution (SED) of a source, similar to spectroscopy with R~15. We installed these filters to SED camera for QUasars in EArly uNiverse (SQUEAN) on the 2.1m telescope at McDonald Observatory, and conducted test observations of known high redshift quasars at $4.7{\leq}z{\leq}6.1$ and also dwarf stars for comparison. We found differences in SED shapes between high redshift quasars and dwarf stars, determined their locations on color-color diagrams, and demonstrated that the medium-band filters can enhance the efficiency of selecting robust quasar candidates in this redshift range. In this poster, we propose an effective selection method of high redshift quasars using these medium-band filters and discuss its effect on our high redshift quasar survey.

This thesis is purported to contemplate glamour look reflected in fashion history, thereby to establish the styles of glamour expressed in fashion trends and to provide the categorical basis of fashion design. For such purposes, this thesis first provides the historical survey on the glamour look in fashion, and to conduct a case study by conducting survey of fashion photographs captured in an internet site called Firsview(www.firstview.com) during most recent ten-year period covering $pr\^{e}t-\`{a}-porter$ design products presented by ten leading Italian designers. Based upon the historical survey, there are four representative styles in glamour looks, including (1) luxury glamour, (2) hyperfeminine glamour, (3) kitsch glamour, and (4) romantic glamour. Luxury glamour looks were most often utilized by fashion designs of Valentino and Armani, which can be characterized by frequent usage of glittering details intended to emphasize the surface decoration. Hyperfeminine glamour looks were characterized by the frequent usage of black color in an effort to create fetish atmosphere or sensuality, which can be discovered from the fashion designs of Versace, Cavalli and Ferre. Kitsch glamour looks were characterized by the appropriation of details of vulgar subcultural features mixed with strong color combinations and ethnic trimmings. Versace, Cavalli and Dolce & Gabbana were the main designers of kitsch glamour looks. Finally, romantic glamour looks, which were mainly expressed by Valentine, Dolce & Gabbana and Versace, were characterized by nostalgia and luxury with light colors and materials such as lace and transparent fabrics.
This study was to investigate the effect of salt alone or in combination with phosphate on physicochemical and textural properties, and chemical interactions of low-fat model sausages. pH, color, expressible moisture (EM), cooking loss (CL), proximate analysis, textural profile analysis and low-vacuum scanning electron microscopy were performed. As salt content increased, color tended to decrease, as did EM and CL parameters, indicating that the ability to retain moisture was improved with increased salt levels (p < 0.05). In addition, textural hardness, gumminess and chewiness all increased with increasing salt (p < 0.05). Sausages with 0.3% salt showed the lowest cohesiveness compared to those with salt levels higher than 0.3% (p < 0.05). Addition of sodium tripolyphosphate (STPP) increased pH of sausages. Increasing salt and STPP did not affect lightness (p > 0.05), but did increase redness and yellowness (p < 0.05). The moisture content was higher when the salt and STPP contents were increased (p < 0.05), but no differences in the fat and protein contents (%) were observed (p > 0.05). EM and CL tended to decrease with increasing salt and STPP. In textural properties, the combination of 1.8% salt and 0.3% STPP was the best among other treatment (p < 0.05). Surface microstructure showed a flat and dense structure with increasing salt and STPP. Since the addition of salt and phosphate improved the functionality, textural and physicochemical properties of meat products in this study, meat products will need to be developed in line with consumer's preference.

The purpose of the present study were 1) to identify the dimensional structure of impression formed of a female figure, 2) to analyze effects of several elements of apparel design on impression formation of the figure in suit. The experimental materials developed for this study were a set of stimuli and a response scale. The stimuli consisted of 60 drawings made by identical manipulations of 3 indepndent variables in 3 clothing styles(suit, dress and pants with blouse). The independent variables were (1) five clothing colors (red, blue, yellow, white and black), (2) two lengths(short/long) of suit skirt, dress, and pants (3) two types of blouse and dress collars (shirt collar/ribbon collar). The 7-point semantic differential response scale to measure the dependent variables (formed impressions of the female figure) was composed of 37 bipolar adjectives. Further- more, two open-ended questions were used for interpretation of the reponses. The study proceeded in three independent experimental part was based on the 3 clothing styles using a 5(color)$\times$2(length)$\times$2(collar) factorial design. Subject were 200 female undergraduate students reandomly assigned to one of 20 combinations in each part of the experiment. The data were analyzed by factor analysis, 3-way ANOVA and Multiple Classification Analysis. Five factors emerged to account for the dimensional structure of impression of the female figure in specific attire. These factors included three basic dimensions of impression identified as potency, activity and evaluation, confirming the results of previous studies. Result from open-ended questionaire supported the theoretical perspective of Schneider, Hastorf and Ellsworth on the procedure of impression formation.
This paper explores the possibility, and suggests an experimental procedure, of industrial application of traditional textile design techniques, such as hand silkprinting and natural dyeing. Theoretical and traditional background of this study is William Morris and his followers' Arts and Crafts Movement from the late 19th century to the early 20th century, which laid the philosophical as well as technical foundations of modern textile design tradition. Based on the basic understanding of the design philosophy, and starting from the design techniques of Morris and his successors, I made some experimental and systematic color plans reflecting and exploiting the physical traits and structure of jacquard woven silk material fabrics. And I applied hand silkscreen printing techniques on the jacquard silk fabrics of my own making, while testing various color combinations of natural dyes. After finishing final processing of design samples, I could get textile design products which met the criteria of my original expectation, i.e., eco-friendly and aesthetic design samples that can also be produced in automatized mass production system of contemporary textile industry. The conclusion of this experimental study is that I can expect the natural dyeing techniques, jacquard silk fabrics design techniques, silkprinting techniques, and the basic processes used in this study to be safely applied for contemporary commercial textile industry utilizing automatized silkscreen printing system and digital printing devices.
Eighty-five different cultivars of Brassica rapa, B. juncea, B. nap us, B. carinata, B. oleracea and hexaploid Brassica collected from Bangladesh, Japan, China and Denmark were analyzed by SDS-PAGE for seed and leaf protein variations, using esterase, acid phosphatase and peroxidase isozyme analysis. Ten polymorphic bands were identified from seed protein however no identifiable polymorphic band was found in the leaf protein. Polymorphic markers clearly distinguished the different Brassica species as well as yellow sarson (YS) and brown seeded (BS) cultivars of B. rapa. The $F_1$ cross between YS and brown seeded cultivars showed the existance of all poly-morphic bands of the respective parents. The Bangla-deshi and Japanese cultivars of B. rapa differed in the amount of seed protein. In the case of isozyme analysis, esterase showed the highest number of polymorphic bands (13) followed by acid phosphatase (9) and peroxidase (5). These polymorphic markers were very effec-tive for classification of all the species studied in this experiment. In parentage tests using isozymes, the hybridity of intra-and-interspecific crosses of almost all the seedlings could be identified from their respective cross combinations. Esterase polymorphism showed a clear differentiation between YS and BS types of B. rapa. In addition, two esterase polymorphic markers were iden ified to differentiate some cultivars of B. juncea. Segregation patterns in these two esterase bands showed a simple Mendelian monohybrid ratio of 3:1 in $F_2$, 1:1 in test cross and 1:0 in back cross progenies. No polymorphic band was identified to distinguish different cultivars of the same species by acid phosphatase or peroxidase. Polymerase Chain Reaction (PCR) was carried out with seed coat color specific marker of B. juncea. The yellow seeded cultivars produced a strong band at 0.5 kb and weak band 1.2 kb. In the addition of these two specific bands, Japanese yellow-seeded cultivars expressed two more weak bands at 1.0 kb and 1.1 kb. Where the brown seeded cultivars generated a single strong band at 1.1 kb. In segregating population, the yellow seed coat color marker segregated at a ratio 15 (brown) : 1 (yellow), indicating the digenic inheritance pattern of the trait.
The Jindo is a Korean native dog, well-known for its hunting and guarding abilities. When he gives his devotion to one individual, he gives it whole-heartedly. He is not tempted easily and impetuous. The breed was not developed. but the dog retained their original qualities -loyal, alert, fearless, obedient, watchful, intelligent, energetic- to survive in the harsh environment of the Jindo island. The dog had been spread over the entire Korean peninsula from the time unknown, and the ones in the Jindo island, isolated until lately, survived and maintained their original characteristics. They are now spread over the entire Jindo County consisted of many islands, whence the breed name came. The Jindo comes in a variety of colors and color combinations, with the fawn and white colorings predominant. The dog is one of the Korean natural monuments, protected by law since early 1960s. The Jindo gained official approval by the Federation Cynologique Internationale as a hunting dog. Apart from the basic housetraining, the dog rarely gets training. Many people have attempted to preserve its pure bloodlines and original qualities. Today, there are a total of 10,356 Jindoes being raised over the entire Jindo County, and many more are kept elsewhere. A research into genetic characteristics of the Jindo is now going on, using the technique of isozyme electrophoresis. The Jindo Dog Breeding Management Center has been reinforced lately, and in addition to their routines, the Center is to work on the breeding of the Jindo. Efforts should be made in the future to produce stable, trustworthy Jindoes according to their proposed use and to modify their temperament in order to make it more widely acceptable as a pet and companion dog in the strangers home.
The application of ganghwa mugwort (GM), ascorbic acid (AC), and their combinations for reduction of residual nitrite contents was analyzed in pork sausages during storage of 28 d. Six treatments of pork sausages contained the following: Control (no antioxidant added), AC (0.05% AC), GM 0.1 (0.1% GM), GM 0.2 (0.2% GM), AC+GM 0.1 (0.05% AC + 0.1% GM) and AC+GM 0.2 (0.05% AC + 0.2% GM). Results showed that the mixture of 0.05% AC and 0.2% GM was most effective for reducing thiobarbituric acid reactive substances (TBARS) and residual nitrite contents than the control and GM added sausages alone (p<0.05). The color values of all treatments were significantly affected by adding GM (either alone or with AC). Additionally, the total color difference (${\Delta}E$) and hue angle ($H^{\circ}$) values of treatments added with GM were higher than those of the control as the amount of GM increased (p<0.05). However, there were no significant differences in the pH values between the control and all treatments during the storage period (p>0.05). Our results showed possible applications of antioxidant combination, for preventing the lipid oxidation and decreasing the residual nitrite levels of meat products.
A total of 340 individuals from seven duck populations were studied using 24 polymorphic microsatellite (MS) markers to identify plumage colors with genetic diversity. The estimated average number of alleles (Na), polymorphic information content (PIC) value, and expected heterozygosity (He) per locus of all populations were 11.5, 0.602, and 0.635, respectively. The calculated population genetic distance (Fst), inbreeding coefficient of individuals within duck populations (Fis), and total inbreeding among populations (Fit) were 0.135, 0.105, and 0.229, respectively. Statistical analyses for each population using 24 marker combinations, revealed that the estimated average number of effective alleles (Ne), observed heterozygosity (Ho), and fixation index of inbreeding within populations (F) were 3.129, 0.505, and 0.104, respectively. The results of genetic distance and phylogenetic analysis revealed that Korean native duck populations were clearly separated from all Bangladeshi duck populations. Moreover, all populations clustered well according to their genetic distance, but could not be clearly separated according to black and white plumage colors or plumage color pattern. The combination of these 24 MS markers can be used for discrimination and determination of the genetic diversity of native duck breeds in further investigations for conservation and special development purposes.
This thesis is a reflection of Korean aestheticism and how it has evolved and influenced Korean contemporary fashion throughout the last century. Up to the current, there have been five notable trends of fashion that have been influenced from and have reflected the qualities emblematic of various periods in Korean history. They can be characterized as the era of Missionary fashion, Uniform fashion, Salon fashion, Brand Name Fashion, and finally, fashion from the current era of diversification. The specific characteristics of each fashion era have been analized and illustrated in a comprehensive table. Design characteristics of Korean contemporary fashion are as follows : 1. A point of emphasis is given to facial feature, unconstructive design and ample silhouette and A silhouette, two-piece and pants. Korean style wrap skirt, a smooth curve and layered style. 2. Effect of flatness from material; as methods of quilting, reinforced dual stitching(Kaeki), patchwork, embroidery and goldfoil thread extra, it is turned up that texture of cloth stuff and effects of flatness. 3. Simple color combinations give effects in two different directions For instance, white and a variety of vivid colors, a dull color and bright colors, black, blue. 4. Over-design, diffusion of fashion. Based on the design characteristics described above, the essence of Korea's beauty consciousness can be captured and summarized through the following points: 1. Emotionalism and non-characterism: traditional and simple natural beauty and modernized natural beauty. 2. From authoritism to non-authoritism: traditional and formal personal beauty and casual characteristic beauty. 3. Polaris (antithesis) phenomenon: chastic beauty and ostentatious beauty, simplicity and lavishness, conformity of fashion and originality. Although the beauty consciousness of Korean contemporary fashion is changing from traditional passive metaphor to aesthetic expressionism for the new generation, after all the basic foundation or root of the spiritual beauty of idealism is usually recognized by focusing on the face.
