The Physics Outreach Unit at UNSW Australia contributes to the goals of the IAU's Commission 55 by collaborating with established institutions to improve public engagement with science. We aim to not only increase public awareness of astronomy but also ensure the benefits to society of our scientific endeavours are understood. We have found collaborating with like-minded institutions who are working in similar spaces allows both parties to make a larger impact than working alone. For example, our long-term collaboration with the Australian Museum provides the opportunity to engage urban and rural communities with science, audiences to which we do not normally have easy access. To increase our national presence we are exploring new relationships with other institutions, in particular the Astronomical Society of Australia (ASA), in hosting events such as public talks with eminent astronomers, star parties and astronomical workshops. These partnerships help build firm foundations for planning future events, in particular during the International Year of Light 2015.

According to Scythian tradition, many burials contained numerous artifacts, from weapons and harness to everyday objects and a multiplicity of personal adornments. Most valuable of all is the Scythian Gold often lavishly decorated with precious stones. The detailed images on these pieces make it possible for us to picture the appearance of the Scythians, their clothes and weapons. Scythian Gold Plaques were attached to the fabric in such a way that when they moved with each movement of the wearer it created what must have been a dazzling sight in bright daylight. Scythian Gold Plaques were divided into several types according to the shape, animal style(curved beast shape, profile shape, head reversed over its back shape), round shape, quadrilateral form, star shape, flower shape, crescent shape, bundle shape, human appearance. Through the antique tombs bequests of Three Kingdom States hereby describe the original forms of their source of Baekje gold plaque were influenced by Scythe style. Like nearly all Scythian ornaments, such gold pieces were designed to maximize various magical powers and to signify the owner's importance relative to his fellow tribesmen.

Henricia specimen was collected from the East Sea of Korea using fishing nets. The specimen was identified as Henricia hayashii (Djakonov 1961), belonging to the family Echinasteridae of the order Spinulosida. This species can be distinguished from other Henricia species by slender arms (R/r=7.4), constricted arm base, six to thirty-five slender spinelets, open-meshed, reticulated abactinal skeleton comprising semi-triangular, rod-like form, and small ossicles present inside the papular areas. This species superficially resembles H. reniossa in terms of its body size but differs in the shape and arrangement of the abactinal and actinal plates. To date, two genera of Echinasteridae, Aleutihenricia and Henricia, including a total of 14 species, have been reported in Korea. Herein, the morphological characteristics of H. hayashii are described, and photographs are provided.

An asteroid specimen that belongs to the genus Henricia was collected from the waters near Ongpo harbor, Jeju Island using fishing net on 24 January 2017. The specimen was identified as Henricia anomala Hayashi, 1973, which belongs to the family Echinasteridae and order Spinulosida. Henricia anomala was first described by Hayashi, 1973, who captured it from Sagami Bay at a depth of 110-116 m. This species can be distinguished from other Henricia species by short arms (R/r=4), abactinal spines lining the abactinal plates and bearing about two to five spinelets, closely meshed abactinal skeleton, composed of small rod-like and subtriangular plates, a narrow papular area containing one or two papulae, and adambulacral armature composed of five to seven bluntly pointed spinelets. This is the first report of Henricia anomala in Korea.

We show that dynamical evolution in a strong (Galactic Centre-like) tidal field can create clusters that would appear to have very top-heavy IMFs. The tidal disruption of single star forming events can leave several bound 'clusters' spread along 20~pc of the orbit within 1-2 Myr. These surviving (sub)clusters tend to contain an over-abundance of massive stars, with low-mass stars tending to be spread along the whole 'tidal arm'. Therefore observing a cluster in a strong tidal field with a top-heavy IMF does not mean the stars formed with a top-heavy IMF.

We selected 47 DOGs at z ~ 1.5 using optical R (or r'), AKARI $18{\mu}m$, and $24{\mu}m$ color in the AKARI North Ecliptic Pole (NEP) Deep survey field. Using the colors among 3, 4, 7, and 9µm, we classified them into 3 groups; bump DOGs (23 sources), power-law DOGs (16 sources), and unknown DOGs (8 sources). We built spectral energy distributions (SEDs) with optical to far-infrared photometric data and investigated their properties using SED fitting method. We found that AGN activity such as a AGN contribution to the infrared luminosity and a Chandra detection rate for bump and power-law DOGs are significantly different, while stellar component properties like a stellar mass and a star-formation rate are similar to each other. A specific star-formation rate range of power-law DOGs is slightly higher than that of bump DOGs with wide overlap. Herschel/PACS detection rates are almost the same between bump and power-law DOGs. On the other hand SPIRE detection rates show large differences between bump and power-law DOGs. These results might be explained by differences in dust temperatures. Both groups of DOGs host hot and/or warm dust (~ 50 Kelvin), and many bump DOGs contain cooler dust (${\leq}30$ Kelvin).

The purpose of this thesis is to study the formative characteristics and symbolism shown in Rock stars' hairstyles through rock music to have influenced youth culture. There were a D.A style and a mop top style which included the youth characteristic to seek a new desire and value as the hairstyles of Rock & Roll stars, along with the characteristics of Rock & Roll music to represent the feeling of teenagers in 1950's at that time unlike the previous music due to high beats mixed with Rhythm & Blues (R & B) and Country music, and use of electronic guitars. We can see the desire for challenge and freedom against the then present regime, shouting love and peace, and resistance in the Psychedelic Rock music stars' hairstyle, which are untrimmed and disheveled, that is, natural. We can find explosiveness in Mohican and Spike style of Punk Rock stars playing fierce and aggressive music, along with words including indignation and assertion against the society's regime. The Artistic characteristic is implied in the following hairstyles: Glam Rock stars' hairstyle, a man's long-haired but a little long crew-cut style to reduce the bulky feeling and to give a bisexual, visible shock with hair dyed in orange to emphasize magnificence, and Punk Rock stars' hairstyle showing beauty in their own way with expression of anti-beauty to intentionally look ugly. Like this, the 20th Century's Rock music and youth culture are closely associated each other, and showed a new style, and played a leading role in street fashion, which became a momentum to much influence high fashion as a look of the 20th century modern fashion.

Cultural sensation by appearance of Elvis Aaron Presley is thought to have been greatly influenced by spread of popular culture beginning to form with the development of mess media in USA that was changed rapidly after the war, changing aspect of popular music in U.S.A through the media development and teenager culture of USA that has rapidly emerged. Elvis intended to change into 'music to be seen' deviating from 'music to be simply listened to' with expressing the conversion of sexual consciousness, defiance to older generation and a sense of value on wealth, and the like, and also suggested a new culture and style to the young people at that time. Flow of Elvis's fashion may be categorized into the classifications such as the fashion in the period. First, Formative period(before 1954) distinguished by pimp look and sideburns with tough image and wild clothes. Second, Establishment period(1954-57) may be categorized into the hot rockabilly style which showed a glittering fashion by brilliant and colorful costumes, the cool rockabilly style which changed him to a fashionable star of modem image(1958-60). Third, re-heyday(after 1968) where a brilliant and bold decoration was displayed. In Elvis fashion, the masculine sensualism, defiance to main value and expression of luxury and consuming culture, etc. are included as a unique aesthetic consciousness. 'Expression of masculine sensualism' represented the sensualism through sexual objectification of men's body by men's sexual ostentation which was prohibited. 'Defiance to main value' means that attempts of non-mainstream image for social class are expressed with an exercise of power by young people through the public. Although the Elvis look has fanned an anti-culture, it was expressed and accepted as having a normally capitalistic appearance. In addition, it being thought of as the standard, symbolizing a success and a wealth through the presentation of image which accepted this material benefit, we may classify this into 'expression of luxury and consuming culture'.

이 연구는 한국 영화의 일본 수출이 급격하게 증가한 지난 2002년부터 2006년까지 한국 영화 개봉작 436편을 대상으로 장르와 한류 스타 출연 여부, 메이저 배급 여부, 국내 관객수 등에 따른 일본 수출 성과를 살펴보고자 했다. 우선 장르 면에서는 멜로 영화의 수출 비중이 가장 높아서, 코믹 영화를 즐겨보고, 멜로 영화에 대한 선호도는 다소 저조한 한국 관객과의 차이를 보여준다. 또한, 한류 스타가 출연한 영화 비중은 전체 개봉작의 14%에 지나지 않았으나, 한류 스타가 출연한 영화의 일본 수출 비중은 비한류 스타 출연작에 비해 월등히 높은 것으로 나타나, 일본 수출에 있어 한류 스타의 중요성을 입증해주고 있다. 뿐만 아니라, 메이저 배급 여부와 국내 개봉 성과 또한 일본 수출과 통계적으로 유의한 결과를 나타냄으로써, 배급사의 브랜드 파워와 개별 영화의 1차 시장 성적이 후속 시장에 영향을 주고 있음을 알 수 있다.

This paper proposes the architecture and protocol of a data communication network for the safety system in nuclear power plants. First, we establish four design criteria with respect to determinability, reliability, separation and isolation, and verification/validation. Next we construct the architecture of the safety network for the following systems: PPS (Plant Protection System), ESF-CCS (Engineered Safety Features-Component Control System) and CPCS (Core Protection Calculator System). The safety network consists of 12 sub-networks and takes the form of a hierarchical star. Among 163 communication nodes are about 1600 origin-destination (OD) pairs created on their traffic demands. The OD pairs are allowed to exchange data only during the pre-assigned time slots. Finally, the communication protocol is designed in consideration of design factors for the safety network. The design factors include a network topology of star, fiber-optic transmission media, synchronous data transfer mode, point-to-point link configuration, and a periodic transmission schedule etc. The resulting protocol is the modification of IEEE 802.15.4 (LR-WPAN) MAC combined with IEEE 802.3 (Fast Ethernet) PHY. The MAC layer of IEEE 802.15.4 is simplified by eliminating some unnecessary (unctions. Most importantly, the optional TDMA-like scheme called the guaranteed time slot (GTS) is changed to be mandatory to guarantee the periodic data transfer. The proposed protocol is formally specified using the SDL. By performing simulations and validations using Telelogic Tau SDL Suite, we find that the proposed safety protocol fits well with the characteristics and the requirements of the safety system in nuclear power plants.
