The bidimensional empirical mode decomposition (BEMD) algorithm with high adaptability is more suitable to process multiple image fusion than traditional image fusion. However, the advantages of this algorithm are limited by the end effects problem, multiscale integration problem and number difference of intrinsic mode functions in multiple images decomposition. This study proposes the multiscale self-coordination BEMD algorithm to solve this problem. This algorithm outside extending the feather information with the support vector machine which has a high degree of generalization, then it also overcomes the BEMD end effects problem with conventional mirror extension methods of data processing,. The coordination of the extreme value point of the source image helps solve the problem of multiscale information fusion. Results show that the proposed method is better than the wavelet and NSCT method in retaining the characteristics of the source image information and the details of the mutation information inherited from the source image and in significantly improving the signal-to-noise ratio.

Direct membrane filtration (DMF) of wastewater has many advantages over conventional biological wastewater treatment processes. DMF is not only compact, but potentially energy efficient due to the lack of biological aeration. It also produces more biosolids that can be used to produce methane gas through anaerobic digestion. Most of ammoniacal nitrogen in wastewater is preserved in effluent and is used as fertilizer when effluent is recycled for irrigation. In this study, a technical feasibility of DMF was explored. Organic and nitrogen removal efficiencies were compared between DMF and membrane bioreactor (MBR). Despite the extremely high F/V ratio, e.g., $14.4kg\;COD/m^3/d$, DMF provided very high COD removal efficiencies at ~93%. Soluble microbial products (SMP) and extracellular polymeric substances (EPS) were less in DMF sludge, but membrane fouling rate was far greater than in MBR. The diversity of microbial community in DMF appeared very narrow based on the morphological observation using optical microscope. On the contrary, highly diverse microbial community was observed in the MBR. Microorganisms tended to form jelly globs and attach on reactor wall in DMF. FT-IR study revealed that the biological globs were structurally supported by feather-like materials made of secondary amines. Confocal laser scanning microscopy (CLSM) study showed microorganisms mainly resided on the external surface of microbial globs rather than the internal spaces.

인류는 생존과 더불어 먹는 것 다음으로 아름다움에 대한 욕망의 표출로 신체장식을 하기 시작하였다. 이러한 장식은 수치심이나 추위, 더위 등 외부로부터 신체를 보호하기 위한 의복보다 먼저 시작되었으리라 추정된다. 이는 장식 유물이 복식사에 앞서 출토되고 있기 때문이다. 일예로 현대문명의 혜택을 전혀 받지 못하는 오지의 원주민의 경우, 의복이나 도구의 본능적 기능보다 장식이 화려한 경우를 볼 수 있다. 이러한 장신구의 역사는 원시시대의 동물의 이빨 등의 사냥물에서부터 현대의 신소재에 이르기까지 다양하게 발전되어 왔다. 본 논문은 한국장신구의 시대적, 재료적 자료를 통하여 장신구 문화콘텐츠를 연구함으로써 문화유산을 통한 문화상품을 개발하고 발전시키는 과정으로 장신구 콘텐츠개발에 기여하리라 본다.

The huge amount of demand for feedgrains from this region could not possibly be met by producing countries from the other regions. In order to fulfill this increasing demand for conventional raw materials, an alternative for the conventional raw materials produced in the Asia and Pacific region is becoming increasingly more important. A potential alternative is concentrates or non-conventional concentrates produced locally in relative abundance in this region. These feedstuffs include feed grains, by-products from the milling, sugar industries, brewing and distilling industries. Vegetable, citrus, and animal by-products from abattoir, feather meal and blood meal are also possibilities. In addition to more widespread use of unconventional feed sources, the following approach is recommended to improve utilization and performance. These include establishing the nutritive value of non-conventional feeds, quality control to minimize variability, proper storage and processing to assure the nutritive value and prevent mycotoxin contamination, properly balance amino acids with protein sources, supplementation with synthetic amino acids and the use of enzymes to increase digestibility. Currently, practical applications for these resources in feed formulation are negligible despite the potential. The socio-economic aspects will dominate the use of these non-conventional concentrates. In the future, the feed industry will resolve the problems in using locally available raw feed materials.

The aim of this study was to determine the effects of breeder age and stocking density on performance, carcass characteristics and some stress parameters (H-L ratio, serum glucose, cholesterol and triglyceride levels, tonic immobility test (TI), antibody production, relative asymmetry (RA) and external appearances). This experiment was carried out with 705 one-day old male broiler chicks (Ross 308) obtained from three different ages of broiler breeder (32, 48 and 61 wks). Each age group was randomly divided into two stocking density groups (11.9 and 17.5 broilers per $m^2$) with 5 replications per group. The experimental period was 6 weeks. Broilers from 32 wk-old breeders had lower initial weight (p<0.001), body weight gain of the first 3 week of rearing (p<0.01), the percentage of abdominal fat (p<0.001) and serum cholesterol level (p<0.01); higher percentage of gizzard (p<0.01) and longer TI duration (p<0.001) than those from 48 and 61 wk-old breeders. Broilers reared at 17.5 b/m2 had lower final BW, body weight gain, feed consumption, feather condition and foot health (p<0.001), higher percentage of heart, H-L ratio, serum glucose and cholesterol levels (p<0.001), and longer TI durations (p<0.001). There were no significant interactions in examined parameters except for feed to gain ratio between breeder age and stocking density.

Bio-imaging and drug carriers for delivery have created a huge demand for crystals. Crystals are fascinating materials that have been grown for a long time but obtaining biocompatible fluorescent crystals is a challenging task. We report on the growth of fluorescent crystals using a carbon dot (C-dot) solution by a hydrothermal process. The crystallization pattern of these C-dots exhibited a unique dendritic structure having a feather-like morphology. The growth temperature and pressure were maintained at 60℃ and 200 mmHg, respectively, for crystal growth. A green fluorescence (under UV light) that was observed in the C-dot solution was retained in the crystals formed from the solution. Cytotoxicity studies on Vero cells revealed the crystals to be extremely biocompatible. These fluorescent crystals are extremely well suited for biomedical and optoelectronic applications.

This study was conducted to evaluate the possible utilization and the replacing range of fish meal analogue (FMA) as a dietary animal protein source for fish meal replacer in fingerling common carp, Cyprinus carpio. Leather meal, meat and bone meal, feather meal, squid liver powder, poultry by product meal, blood meal and amino acids were selected as ingredients for FMA. fish averaging 12.5 g were fed one of five isonitrogenous and isocaloric diets containing fish meal and/or FMA as the dietary animal protein sources. Fish meal protein (0, 20, 40, 60 or 100%) was replaced by the graded level of FMA protein. The feeding trial was conducted for 12 weeks after one week of conditioning period. Percent weight gain of fish fed diets containing 20%, 40% and 60% FMA were not significantly different from that of the fish fed the control diet (P>0.05). Feed conversion ratio of fish fed diets containing 20%, 40%, 60% and 100% FMA were not significantly different from that of fish fed control diet. These findings suggest that replacement of fish meal protein by FMA could be possible up to 60% of fish meal protein in fingerling Israeli carp diets.

The purpose of this study was to research Korean Jowoo-Guan and Chinese Hal-Guan and study transition and symbolism of the birds feather in the cap. The culture of ancient Korea was influenced by North Asia prior to the influence of the Chinese culture, One of the remarkable thing, as the cultural factor of North Asia is the birds worship thought. Korean Jowoo-Guan was derived from the birds worship thought. So in dealing with the plume of Korean Jowoo-Guan, we must recognize Worship to the bird and the symbolical meaning of the bird. The results of study was as follow. 1. Korean Jowoo-Guan was influenced worship to the sun, so it's wearing symbolized the governing class. As the Social development and governing class, the feathering cap was developed to a gold crown, and also the gold crown of Samguk times had been influenced style of North Asia culture. But afterwards the symbolical meaning of the bird was waning, only decorative meaning was remained. 2. Chinese Hal-Guan was warn in Joo-dynasty, but the symbolism of the plume in the cap was not similar to Korean Jowoo-Guan. Chinese Hal-Guan was symbolized bravery of superfluous soldier than Worship to the bird. But afterwards the symbolical meaning of bravery of superfluous soldier was waning, only decorative moaning was remained. 3. Though neighbor countries have mutually influenced and have similar cultural style, they have symbolism of themselves

The purpose of this study is to analyze the formative relationship between clothes and hat with the works by Philip Treacy, the designer who raised hats to one of important fashion accessories. The method to analyze the relationship between clothes and hats was the formative analysis by Marian L. Davis and Marilyn R. Delong. The results suggest that clothes and hat had an organic relationship, and a hat style was changed with formative elements of clothes. Clothes and hats by Philip Treacy were analysed in the aspects of Form, Color, Material, and Decoration. As a result, hats by Philip Treacy were mainly designed by the relationship between whole types without a closed line and showed geometric and formative forms, similarly harmonized with clothes. To highlight hats, the achromatic colors such as black and gray were used. Besides clothes and hats were coordinated by the same colors, but contrary colors were used to express a strong image. Felt or straw materials maily used to express a formative and fixed form were well matched with smooth, opaque, and lusterless materials such as wool. Also when transparent materials were used for hats, lace was used for clothes. A hat made of acrylic was matched with clothes made of glossy vinyl coating materials. Decoration was mainly removed but if used, feather decoration was added to clothes.
