The purpose of this paper is to explain the recipient's psychology, which results from the operation of media, from the perspective of the fluctuation between immersion and contemplation. Media allow to perceive and speculate about specific objects or meanings. In addition, the media perform the function of expanding or changing the objects of perception and thought. McLuhan or Luhmann's media theory emphasized this function of changing the state of perception by inducing a contemplative attitude. This notion is exemplified by interpretation of the visual media history. In this paper, the cases of film and computer game are discussed. In particular, it is considered that VR media causing strong immersion have also developed in a way that allows recipients to contemplate an virtually constructed reality. The commercialization of Tilt Brush and the experimentation of VR painting artwork are the examples for this dual development.

The purpose of this study is to explore the differences in aesthetic experience according to the level of audience participation. Flow experience and aesthetic distance were utilized as proxies for aesthetic experience. A total of 70 undergraduates participated in the experiments of this study. In terms of flow experience, active participation groups were found to have relatively greater flow experiences compared to contemplation groups and passive participation groups. However, there was no difference in flow experience between the contemplation groups and the passive participation groups. In light of aesthetic distance, which means psychological distance, people in active participation groups were found to have a closer psychological distance from artwork than those in contemplation groups and passive participation groups. Also, those who belonged to the passive participation group showed a closer psychological distance than the contemplation group. The results of this study provide artists and art organizations with implications for enhancing audience attraction as well as the completeness of artwork.

최근 기후변화로 인해 집중호우 및 게릴라성 폭우의 발생빈도가 증가하고 있다. 또한, 도시화 및 산업화로 인해 불투수지역이 증가하여 첨두강우의 도달시간은 짧아지고, 강우강도는 증가하는 현상을 보이고 있다. 이로 인해 도시유역에서는 우수관의 통수능 부족으로 인한 홍수가 빈번히 발생하고 있다. 본 연구에서는 EPA-SWMM User's manual에서 제공하는 예제 관망도를 이용하여 SWMM 모형 매개변수들 간의 상관관계 분석을 수행하였다. 사전 조사 및 분석을 통해 유역폭, 관조도계수, 불투수유역 조도계수, 투수유역 조도계수, 불투수면적 비율 등 총 5개의 매개변수를 분석 대상으로 선정하였다. 매개변수들 간의 상관관계를 분석한 결과 유역폭-관조도계수, 유역폭불투수유역조도계수, 불투수면저 비율-투수유역 조도계수가 양의 기울기를 가지는 1차 선형함수 형태를 보였다. 즉, 예로 유역폭이 증가하면 관조도계수 또한 증가하는 경향을 보였다. 반대로 유역폭-불투수면적비율, 불투수유역 조도계수-관조도계수의 경우 음의 기울기를 가지는 상관관계를 보였으며 특히, 유역폭-불투수면적비율의 경우 2차 회귀곡선을 가지는 감소경향을 보였다. 본 연구의 결과를 활용하여 향후 우수관 설계를 수행한다면 내수침수 저감에 실무적인 도움을 줄 수 있을 것으로 판단된다.

연구배경 : 상부위장관 조영술결과 유소견을 보인 환자와 그들이 호소하는 증상, 그들의 사회적 환경, 생활특성이 어떠한 관련이 있는가 알아보고자 하였다. 연구대상 : 1995년 1월부터 1997년 12월까지 제일생명(주) 부속의원 종합검진센타에 내원한 8,982명을 대상으로 상부위장관조영술을 시행하고 이와함께 상부위장관 증상에 대한 설문조사를 시행하여 그 결과를 분석하였다. 결과 : 상부위장관 조영검사자 총 8,982명중 유소견자는 598명(6.66%)이며, 그중 남자 420명(70.24%), 여자 178명(29.76%)으로 나타났다. 유소견중에는 십이지장 궤양이 제일 많았으며 그 중 남자 $30{\sim}40$세에서 제일 많이 발견되었다. 증상발현율은 진단결과와 다른 큰 차이가 없었으며 각 증상중에 진단결과와 유의한 관련을 갖는 것은 없었다. 결론 : 상부위장관 증상은 기질적 원인보다 성별, 연령이나 생활환경의 영향을 더 받는 것으로 보여 진단에 있어 호소하는 증상을 고려하기보다 위장관조영술과 더불어 상기요인에 대한 고려가 필요하다.

본 연구는 조선시대 관폭도를 중심으로 옛 선인들의 명승 인식 태도에 관하여 살펴보고자 하였다. 연구결과 폭포 표현은 폭포의 형상이나, 조망하는 대상에 있어서 차이가 있지만 관념 산수에서의 폭포가 지니는 의미는 변하지 않았다. 폭포는 이상향과 속세의 경계이면서 동시에 관조의 매개체가 되었고, 단순히 풍경의 의미가 아닌 관조적 대상의 장면으로 인식하는 경향이 컸다.

In contemporary art, the process of appreciating art works requires the dichotomy between traditional art and New Media Art. This difference can be witnessed in the contrasting ways of appreciating art works; in traditional art, a certain physical and esthetic distance is placed between viewers and works of art, and in New Media Art, art is appreciated by active involvement and communication. In other words, this disparity is based on whether viewers physically involve themselves in the completion of the art works. Perhaps contemporary art can be better understood and appreciated if a single primary keyword takes the center place of art appreciation rather than allowing the dichotomy. Thus, a new approach is welcome, where art appreciation is not adversely affected through such divided means based on the degree of active participation. This is not some new introduction of jargon but the reinterpretation of contemplation, the key word for art appreciation in the past, as the common key word for both conventional art and New Media Art.

In the case of rapidly developed urban and industrial complex, the most area becomes impervious, which causes the increasing runoff and high probability of flooding. SWMM model has been widely used to calculate stormwater runoff in urban areas, however, the model is limited to interpreting the actual natural phenomenon. It has the uncertainty in the model structure, so it is difficult to calculate the accurate runoff from the urban basin. In this study, the model parameters were investigated and uncertainty was quantified using Uncertainty Quantification Index (UQI). As a result, pipe roughness coefficient has the largest total uncertainty and largest effect on the total runoff. Therefore, when the stormwater pipe network is designed, pipe roughness coefficient has to be calibrated accurately. The quantified uncertainty should be considered in the runoff calculation. It is recommended to understand the characteristics of each parameter for the prevention and mitigation of urban flood.

Radiation dose to radiologists working at three hospitals in Seoul was investigated from Jan 1, 2006 to Dec. 31, 2006. The results are as follows. First, radiation dose to radiologists at a cardiac angiography room was measured as 1.41mSv, the highest while radiation dose to radiologists at a department of radiation oncology was measured as 0.64 mSv, the lowest. Second, radiation dose proves to be in direct proportion to the number of X-ray treatment. Third, as for the radiation dose in X-ray treatments, radiologists in cardiac angiography room are exposed to the largest amount of radiation while radiologists in diagnostic radiology department are exposed to the smallest amount of radiation. Last, radiation dose at a cardiac angiography room is the largest and is followed by nuclear medicine, diagnostic radiology, and radiation oncology departments in order. According to ICRP, exposure less than 20mSv per year is highly recommended while radiation dose is allowed as long as it is ranged less than 50mSv per year or 100mSv within a 5-year period. Taking into account the results, radiation exposure does not do any harm to radiologists at any related departments in Korean hospitals because the dose per year is less than 1.60mSv.
