A two-year-old male peacock (Pavo cristatus) showed acute watery green diarrhea, followed by neurological signs including torticollis and muscular tremor. By the hemagglutination inhibition test for detecting the antibody against the Newcastle disease virus (NDV), the peacock serum inhibited the agglutination of chicken red blood cells. Grossly distinctive hemorrhagic lesions were found in the mucosa of proventiculus and intestine and lung. The spleen revealed multiple variable sized necrotic foci. Histologically, the mucosa of gastrointestinal track had hemorrhagic lesions and some of them underwent ulceration. The spleen exhibited multiple variable sized necrotic foci in which fibrin exudation was marked. Central nervous system had mild non-suppulative menin-goencephalitis consisting of vasculitis, perivascular hemorrhage, gliosis and meningitis. The cells particularly in the cerebellum were degenerative to necrotic. Some of these nerve cells revealed characteristic peripheral chromatolysis. From the present serological and pathological findings, it is suggested that NDV causing death of peacock was velogenic viscerotropic strain. This is the first report of the occurrence of velogenic viscerotropic NDV in an adult peacock in Korea.

The radiation characteristics of a high-luminance light-emitting diode (LED) light source were studied to evaluate its potential as an energy-saving light source for fishing lamps. The angle of the LED light source with 50% illuminance was $8-15^{\circ}$, and it had strong directional characteristics. The wavelengths at which the radiance and irradiance were maxima were 709, 613, 473, 501, 525, and 465 nm for red, orange, blue, peacock blue, green, and white light, respectively. The underwater transmission characteristics of the LED light source were superior in the order blue, white, peacock blue, and green in optical water type I: blue, peacock blue, white, and green in optical water type II; and blue, peacock blue, green, and white in optical water type III. Setting the underwater transmission characteristics of the LED light source in optical water type I at 100%, the transmission of water types II and III decreased to 67 and 17%, respectively. Based on the underwater transmission characteristics calculated in optical water types I-III, the blue and peacock blue LED light sources can be used as an energy-saving light source for fishing lamps.

This study aims to explore the potential of integrating traditional Indian motifs into modern textile design that appeals to the MZ generation. The objective is to create patterns that reflect the rich cultural tapestry of India while aligning with contemporary sensibilities. To achieve this, the design process includes a comprehensive literature review on the historical background, symbolism, and structure of Indian textiles and a survey to determine if the developed design suits the preferences of the MZ generation. Digital design tools such as TexPro, Photoshop, and Illustrator were used to create the designs based on the theme 'Cosmic Dream,' with sub-themes inspired by nature and Indian symbolism. 'Blooming Cosmos' focused on the structural beauty of the lotus, combined with paisley and rangoli patterns, for a vintage yet modern appeal. 'Cosmos in Blossom' is drawn from the rangoli technique of using varied materials, resulting in a romantic pastel-themed pattern that aligns with the 2023 Youth Trend. 'Cosmic Peacock' presented a lively ethnic pattern by merging simplified lotus motifs with India's national bird, peacock along with a paisley backdrop. A questionnaire was conducted to check the MZ consumer responses, and the most preferred design was the peacock and rangoli mixed design, ground colored in cream. These findings indicate the potential of the developed ethnic designs to be used for various purposes. By combining traditional motifs of India with modern elements, this study proposes ethnic textile designs that are suitable for MZ generation consumers.

This study was conducted for investigation of habitat and development of indoor-rearing conditions of peacock butterfly, Inachis io (Linnaeus). Three different region, Mt. Kwangduk-san, Mt. Hae-san and Mt. Taebaek-san in Kangwon-do, was selected for investigation of domestic distribution and ecological environment of peacock butterfly. In result, there are many butterflies in the only two region, Mt. Kwangduk-san and Mt. Hae-san. On 16th April, 4 overwintered butterflies were observed in Mt. Hae-san. At the end of June and early in July, 51 individual next generation's butterflies were observed in Mt. Kwangduk-san and Mt. Hae-san. For development of indoor-rearing conditions, collected each 15 male and female peacock butterflies was reared in a room condition. Female butterflies laid eggs in the egg cluster on the underside of host-plant's leaves, Urtica angustifolia Fisch., in the ovipositioning room. We took 11 egg cluster with average $404.6{\pm}23.6$ eggs. Hatchablity of eggs was 92.3%, and the eggs hatched within $5.1{\pm}0.9$ days from the day of oviposition under high temperature, long day condition($25^{\circ}C$, 14L:10D). The larval period was $18.3{\pm}1.0$ days under high temperature, long day condition($25^{\circ}C$, 14L:10D), showing 81.0% pupal ratio. The head width of each developmental larval stage were $0.37{\pm}0.01mm$(1st instar), $0.66{\pm}0.02mm$(2nd instar), $1.07{\pm}0.05mm$(3rd instar), $1.81{\pm}0.07$(4th instar), $2.76{\pm}0.08$(5th instar).

Online streaming wars are intensifying. Netflix is known as the market leader in the streaming business. However, since 2019, Netflix has been losing subscribers in the United States and is at a turning point where it needs to reassess its current position in the market. While Netflix is losing dominance, rivals Amazon Prime and Hulu continue to gain market shares. Studies from Deloitte and PricewaterhouseCoopers indicated a new shift in the streaming landscape caused by the abundance of streaming options and rising subscription costs. Recent surveys showed that consumers are excited about new streaming services, such as Disney +. Nearly two-thirds of consumers intend to terminate or downgrade one or more of their current subscriptions to make room for a new service. Moreover, it seems that consumers want ad-supported options. In Deloitte's latest Digital Media Trends survey, 65% responded that they would watch ads to eliminate or reduce subscription costs. Seventy percent of Hulu's subscribers choose its lower-priced ad-supported plan. NBC recently launched its own streaming service, Peacock, with a free ad-supported option. This opposes Netflix's brand identity of "no ads" and premium differentiation. With increasing pressure from competition and the growing risk of subscriber loss, Netflix needs to diversify its price plans. The company could try implementing the lower-priced mobile-only plan they are currently testing or plan to test in other regions. Netflix should also consider features or benefits for loyal subscribers to maintain a stronger consumer base.

The purpose of this study was to develop regional dance contents in order to receive attention from the region and re-illuminate the peacock fan, the intangible cultural property of Seocheon, Chungnam, which has been preserved in history and has been preserved in the face of rapid urbanization and modernization. The representative four series are composed of one-person dance, two-person dance, military dance, and creative dance. The titles of each piece are basic dance , male and female love dance , military dance , and finally Korean creative dance . The commonality of the four series is the traditional dance using peacock fan, and each dance showed unique emotion and atmosphere through different themes and music, costumes, and stages. It was found that the development of regional dance contents re-created reflecting the characteristics of regional cultural heritage should create an environment that can be steadily revitalized through modernization. Through this study, it was found that the intangible cultural properties, which are our traditional cultural resources, have unlimited potential to contribute to enhancing regional and national competitiveness along with the growth potential of regional differentiation. Through such research, if existing cultural resources are preserved for globalization and produced as contents that can be easily accessed by the public, various contents besides regional dance using regional unique culture can be developed and utilized.

The purpose of this study is to examine the pieces of 100 fabrics excavated from unknown woman's tomb Incheon, by analyzing woven methods, names of the fabrics, the kinds and the shapes of the patterns. The characteristics to assume the period of the fabrics are as follows. The geumsundan which was woven peacock insignia at chest and back area was excavated for the first time from the tomb of Joseon. Peacock insignia woven with satin weave using supplementary golden wefts, wrapped gold thread. These kind of fabrics were usually imported in the $15^{th}$ century, according to the old documents, 'Nogeoldae' 'Joseonwangjosilrok' written at the end of Goryeo or early in Joseon. Thus, these relics are from about $15^{th}$ century. From this tomb, the mixture fabric of cotton and ramie are excavated. According to another excavated cases, the mixture fabric of cotton and ramie appears from the period before the Japanese Invasion of Korea in 1592, and after the invasion, there are usually mixture fabric of cotton and silk. This also tells that these fabrics show the characteristics of those from the early period of Joseon Dynasty. The rounded patterns of Jangot is only shown from the fabrics of late Goryeo Dynasty, and the cloud pattern of an upper garment with a squared neckline is shown from the early Joseon Dynasty. So, the patterns from these excavated costumes are ranged from the late Goryeo Dynasty to the early Joseon Dynasty. To assume the period through the overall study above, these relics show the characteristics of the $15^{th}$ century fabric.

Patterns in clothing symbolize some specific meaning that differs across cultures and religions, although patterns have been mostly used to realize human desires to overcome natural hazards in every culture or religion. This research aims to compare animal patterns of Korea (Confucian/Buddhism culture) with those of Byzantine (Christian culture), based upon a research method of literature survey. It is found through the research that both cultures used common patterns, such as dragon, butterfly, bat, honeybee, peacock, fish, and chicken. In the case of dragon patterns, Korea used it to symbolize emperor, dignity, or authority, while Byzantine used it for devil. Bat patterns had different symbolic meanings in both cultures: they mean happiness, longevity, prosperity or many off-springs in Korea while they mean misfortune or unhappiness in Byzantine. On the other hand, the rest of animal patterns, including butterfly, honeybee, peacock, chicken, had quite a similar symbolic meaning. Butterfly means change of life or beginning of new life in Korea, whereas it means resurrection in Byzantine. Honeybee symbolizes diligence, order, and cooperation. Many animal patterns were used in both cultures at the same time. Another difference can be found in terms of the kind of animals; for example, Korea used wild goose, pheasant, giraffe, deer, mandarin duck & turtle, while Byzantine used eagle, snake, pigeon. Of course, each and every animal has its own meaning, mostly positive. Except dragons and bats, both cultures have a similar meaning in most of animal patterns. Generally speaking, Korea used imaginary animals to pray for human happiness, but Byzantine used real animals to pray for resurrections.
