An experimental study was carried out to investigate the effect of the inclination angle on the nucleate pool boiling of saturated water at atmospheric pressure. We considered an annulus with a gap of 5 mm and a bottom opening. The inner tube of the annulus was heated, and the outer diameter and the length of the tube were 25.4 mm and 500 mm, respectively. The inclination angle was varied from horizontal to vertical. The results were compared to those for an annulus with a larger gap and a single tube. In the small-gap annulus, the effect of the inclination angle on the heat transfer was not significant. However, an early onset of the critical heat flux was observed at 80 kW/$m^2$ when the annulus was horizontal. Liquid agitation and bubble coalescence were considered to be the major heat-transfer mechanisms.

수평으로 놓여진 2개의 동심타원 사이의 환상공간에서의 자연대류현상이 수치계산 및 실험적으로 연구되었다. 수치적 연구는 정상 2차원 층류유동영역에서 수행되었으며 유선 및 등온선이 구하여 졌다. 또한 특수한 경우로서 수평동심원 사이의 환상공간에 관한 기존연구와 비교하여 좋은 일치 를 보았다. 실험적 연구에서는 3개의 실험모델을 제작하였으며 마하젠더 간섭계에 의한 간섭사진 으로부터 등온선 분포를 얻었으며 아울러 유동에 관한 정보도 얻을 수 있었다. 실험과 수치계산 결과는 상당히 좋은 일치를 보였으며 기존 동심원환상공간에 편심율이 추가된 이론전개 및 수치 계산방법의 적합성을 알 수 있었고 이로서 환상공간에서의 자연대류에 관한 연구를 확장시켰다.

To investigate pool boiling heat transfer in a vertical annulus with closed bottoms, the length of an outer tube was varied between 0.3 and 0.6 m. For the test, a heated tube of 0.2-m length and 19.1-mm diameter and water at atmospheric pressure were used. To elucidate the effects of the outer tube length on heat transfer, the results for the annulus were compared with data for a single unrestricted tube. The increase in the outer tube length resulted in an increase or decrease in heat transfer depending on the gap size. This tendency is mainly attributed to the difference in the intensity of liquid agitation.

Cultural Content industries based on imagination and creativity are attracting attention and the animation high value-added industry is still spotlighted. Among them, Disney Studios make money through using their professional skills. There are the know-how has developed for a long time, and there are timeless strategy. This study is analyzing by fantasy elements for knowing the messages of Disney animation. Fantasy defined as genre of literature by Todorov and Jackson emphasized its social role and significance. Hume expanded the area of fantasy and Tolkein Jahoriski and Boyer classified the fantasy according to the purpose. Through the analyzing Disney animation , Disney's fantasy show the specific expression depending on the target. Disney is based on the three types of fantasy depending on the growth of the journey. The first area is composed of the main character's growth and satisfy the desire and escapism, The second is the word of antagonist who opposed to reality and break the rules of the dominant ideology. The last area is the utopia provided after hero beat the antagonist. Disney characters give the messages by using the fantasy like the transformation or alter ego. That show the subject of the main character's growth and the supporting characters as the expression of the multiple personality of main. These emphasize the hero's growth and give the fun. Also, in the subject of the otherness, the hero always destroy the evil who broke the rules of reality. In this way, the fantasy offered by Disney give the messages of sacrifice and family from true love. Disney has the support of their target audiences continue to be able to convey ideology.

To identify the effects of an outflow area on pool boiling heat transfer in a vertical annulus, three different flow restrictors were studied experimentally. For the test, a heated tube of smooth stainless steel and water at atmospheric pressure were used. Both annuli with open and closed bottoms were considered. To validate the effects of the outflow area on the heat transfer, the results of the annulus with the restrictor were compared with the data for the plain annulus without the restrictor. The reduction of the outflow area ultimately results in a decrease in the heat transfer. As the outflow area is very small, a slight increase in heat transfer is also observed. The major cause of this tendency is explained as the difference in the intensity of liquid agitation cause by the movement of coalesced bubbles. It is identified that the convective flow, pulsating flow, and evaporative mechanism are considered as the important mechanisms.

The film has always reflected the culture of the era based on reality and imagination. The visual effect in the film has mainly played a role of expressing the reality more realistically or recognizing the virtual as reality. This study examines the meaning and the effect of fantasy realism through Oasis of Lee Chang-dong. Fantastic realism has separated the reality from the imaginary space by using a dual meaning tool that affects the time and space in the film and reflects the human desire and desire to see. It was also reproduced in the real world through the medium of pigeons. In addition, it separates visualized space from non-visualized space in film narrative structure, separation of real and unreal space, segregation of consciousness and unconscious space, and separation of reality and reality space into power structure. With the development of technology, the image of the yellow image comes closer to us like reality, which will express the space of unconsciousness that we could not think of.

This study attempts interpretation of the elements of transcendental fantasy appeared in animation. It is about the characteristics of the different spaces from the reality appeared in animation created out of imagination. In regard to the reason why such aspects of fantasy elements appeared in the whole work appear, it presents the three structures including divisional, fantasy and comprehensive structures and characteristics of spatial images of imagination presented in Gilbert Durand's "Les Strutures anthropologiques de l'Imaginaire", through visual nature, depth, and maldistribution. Thus, this study examines the elements in animation . Transcendental fantasy elements give abstract concepts to certain images as it specifically describes them in reality. The fantasy elements operate when it is viewed through the sensibility of the characters. This study attempts to closely approach the issues on how fantasy elements operate in animation.

우리의 현실 속에 비현실을 체험하곤 한다. 매일 밤 꾸는 꿈에서, 가까운 사람의 죽음에서, 컴퓨터 게임이나 시뮬레이션 공간에서 비현실을 감지한다. 현실과 가상의 경계가 모호한 현대사회에서 환상문학이 던지는 반어법적 질문은 오히려 이 시대 인간의 심연과 맞닿아 있다. 이즈음 새롭게 떠오르는 환상문학의 관심은 대표적인 고전작품들 속에서 그 뿌리를 확인해 볼 수 있다. 9인의 문인.평론가가 세계 환상문학의 백미를 가려 뽑아 독자 여러분께 소개한다.

'Fantasy' in this study is Not something fantastic in the used to be-way we can Imagine easily. This study is to figure out 'fantasy' and 'the fantastic' as a significant measure to interpret the contemporary space-time. In particular, it analyzed that fantasy have influenced on some kind of specific trend what is expressed a tendency to contemporary interior designs of informal, indeterminacy and unpredictability. Fantasy is represented as 'the fantastic space' through spatial revealing, concealing, distorting, and connoting. Representation becomes a major issue in almost many kinds of knowledge-system that start from the mind to go out to the world in a realistic or idealistic way. Therefore, the fantastic space reconstructs the reality while making itself through to representational creation-process. It is Important for fantasy and the fantastic space to help detect behind beneath the reality more than what we know.

디지털 테크놀로지의 발달에 따라 디지털게임은 지속적으로 그표현의 가능성을 넓혀왔다. 현실에서촬영할 수없는 많은 장면들이 디지털모핑(morphing)을 통해 영화의 환상적인 장면들을 대체하고 있는 경우만 보더라도 디지털기술은 이미지를 통해 표현할 수있는 한계를 극복하고 있는것이다. 불과 20년전만 하더라도 디지털게임은 현실세계에서 통용 되는 놀이들을 컴퓨터의 연산과 간단한 그래픽을 통해 상징적으로 재현한 수준에 머물렀지만, 최근 들어서는 소설이나 영화보다 더욱 방대한 데이터베이스를 갖춘 가상공간의 세계를 만들어 가고 있다.
