본 연구는 도시적인 관점에서 출발하여 도시와 건축 간의 상호 연관성을 형성하는 방법과 서로의 영역에 대해 어떻게 작용 하는지를 고찰하는데 있다. 현 시대는 급속도로 발전하여 도시와 건축적 측면에서도 많은 영향을 받았으며, 여러 상관성을 가지고 많은 영역에서 변화하고 있다. 하지만 새로운 작업의 유형을 접근하고 시도하는 과정 속에서 기존의 기반시설들과 새로운 종류의 도시들이 생성되고 부서진다. 또한 다른 영역들이 생기고 그냥 스쳐 지나간다. 아무런 느낌과 감정이 구조적 장치인 기능들이 상실된 체 무미건조한 공간으로 버려져 왔다. 그러므로 현대 사람들은 그러한 공간들을 인지하지도 못하고 그냥 없어지거나 버려지는 것이 현 상황이다. 이러한 현상은 시간과 공간이 급속도로 성장하고 변화하면서 수많은 가치관과 문화의 변화와 맞물려 많은 사상을 등장시켰다. 미술에서도 비슷한 상황을 놓고 '낯설게 하기 '로 슈클로프스키는 표현한 것이 있다. 도시와 건축뿐 아니라 미술 분야와 또 다른 분야에서도 이런 부분을 분석하고, 이를 디자인에 적용하고자 하는 지속적인 시도를 겪어왔다. 본 연구는 이러한 입장을 기준으로 도시와 건축에 있어서 주목할 만한 공간의 의미를 되짚어 보고 도시적인 측면의 건축에서 드러나는 또 다른 가치로서의 In-Between Space와 그 영역의 관계와 활용성에 대한 새로운 방법을 탐구하고자 하며, 그 건축화 과정을 통해 드러나는 가능성을 모색하고자 한다. 도시와 건축과의 연관성 속에 표현되고 나타나는 새로운 In-Between Space를 이미지와 영화의 기법(시공간의 압축과 팽창)을 통해 표현적 연결고리를 찾고, 느끼지 못했던 건축 공간을 새로운 실험방법을 통해 분석·창조하여 대입시키는 방법으로 In-Between Space에 대한 근본적인 가치와 가능성들에 대해 실험적으로 연구하는 것을 목표로 한다. 결과적으로 사이트에서 버려진 공간들을 건축적 형태로 출발을 가능하게 할 개념적 영역을 구축하게 되며, 컴퓨터는 이를 시각화하는 '도구' 의 기능을 담당하게 된다. 본 연구에서는 이러한 컴퓨터를 통한 공간적 가능성들을 탐구하고 실제 모델링 스터디를 통해 구체화함으로써 이를 반복하는 작업을 통해 최종적인 건축 형태로서의 'In-Between Space'를 시각화하고 영화적 기법을 통해 공간화 하여 건축 디자인으로 재구성하게 된다. 즉, 버려지고 인지 못하는 In-Between Space를 시각적, 공간적 지각을 형태로 유도되고 변화됨으로서 또 다른 공간과 기능으로 새로운 영역으로서 사람들에게 인식될 수 있는 가능성들을 제시한다. This research refer to starting point within an urban environment and it has formative and interactive between urban and architecture has been consideration. Currently, contemporary culture has been rapidly growth and it has impact between urban and architecture sides, it has varied correlation and changed in various sectors. But during the approach and experience are in processed, the existing facilities and new various constructions are formed and ruined while that time. Also others factors are appeared and passed through in continuously. This has existed without meaning and operational function Therefore, consequently contemporary people are not recognized this changeable environment factors and it has just disappeared in current situation. Thus, phenomenon has developed with space and time appearance. According to one of example in artistic theory, Shklovski expressed that 'unknown state' in historical point of view. They have researched and analyzed in variety of fields such as urban and architecture also part of artistic sectors; they were attempted to transformation and try to application into design sector. This research are retracting and based on between urban space and architecture environment, aspect of both valuable in between space and relevance function are practically use , it will be researched and capability of process in architecture construction. In this research, the objectives will be find out relation between urban and architecture. Firstly, looking at innovative new in-between space to use with image and film techniques to find out relevance matters (compressed and expansion upon space and time) and analysis principle space structures base on new experiences. The research method will be making a new creation and substitution to experience in processes. Consequently this waste space will be reconstructed to build up new sector and visual implement used by computer's techniques. From the research use the computer's techniques to find out capacity of space abilities and embodiment actual model to demonstrate visually 'in-between space' and utilize movie techniques to release the space and it re-composes with construction architecture design. Namely, the In-Between Space time, it is induced space perception with a form and it changes with also as different space and with function new territory, it presents the possibilities and could be recognized in the people.

Purpose Patients receiving high-dose I-131 to treat differentiated thyroid cancer are isolated from visitors to limit radiation exposure to reasonable levels. The appropriate isolation time is unclear and has not been reported in Korea. The purpose of this study was to estimate the isolation time and investigate the possibility of earlier release from isolation. Methods This study was a retrospective analysis of data from 71 patients (10 men and 61 women; mean age, $49{\pm}11.1\;y$) who received 3.7 GBq (47 patients), 5.55 GBq (23 patients), or 7.4 GBq (1 patient) of I-131 between January 2008 and December 2008. The radiation dose was measured with a fixed probe placed inside the isolation room. The total estimated dose equivalent (TEDE) to family members, the time required for the external dose rate to become <0.07 mSv/h, and the time required for whole-body retention to become <1.2 GBq were calculated. Results By the TEDE criterion (<5 mSv), 70 of 71 patients (98.6%) could have been released without isolation. By the external dose rate criterion, 10 of 71 (14.1%) and 60 of 71 patients (84.5%) could have been released without isolation and within 24 h, respectively. With whole-body retention criterion, 19 of 71 (26.8%) and 48 of 71 patients (67.6%) could have been released within 24 h and within 48 h, respectively. Conclusions Appropriate release times were estimated and compared using different criteria. Most patients could have been released without isolation or within 24 h of radiation treatment.

Supercooling phenomena with pure water in freezing process was studied experimantally from -5℃ to 0℃. Temperature distribution and heat transfer were analyzed on the supercooling phenomena according to the initial temperature, inclined angle and temperature of cooling wall were varied. When the water was cooled from the cooling surface, a supercooling phenomena was appeared. After a while dendrictic ice grew sudenly and dense ice layer began to grow from the surface. The supercooling phenomena duration was the longer with decreasing the inclined angle and initial temperature than those of increasing the inclined angle.

Purpose : The clinical availability of 2-deoxy-2-[18F] fluoro-D-glucose (FDG) dual-time point positron emission tomography/computerized tomography (DTPP) has been investigated in diverse oncologic fields. The aim of this preliminary study was to evaluate the relationship between various immunohistopathologic markers reflecting disease progression of colorectal cancer and parameters extracted from FDG DTPP in colorectal cancer patients. Materials and Methods : Forty-seven patients with histologically confirmed colorectal cancer were analyzed in this preliminary study. FDG DTPP consisted of an early scan 1 h after FDG injection and a delayed scan 1.5 h after the early scan. Based on an analysis of FDG DTPP, we estimated the maximum standardized uptake value (SUV) of tumors on the early and delayed scans ($SUV_{early}$ and $SUV_{delayed}$, respectively). The retention index (RI) was calculated as follows: $(SUV_{delayed}-SUV_{early}){\times}100/SUV_{early}$. The clinicopathological findings (size and T and N stages) and immunohistochemical factors [glucose transporter 1 (GLUT-1), hexokinase 2 (HK-2), p53, P504S, and ${\beta}$-catenin] were analyzed by visual analysis. Results : The RIs calculated from the SUVs ranged from -1.8 to 73.4 ($31.8{\pm}15.5$). The RIs were significantly higher in patients with high T stages (T3 and T4) than with low T stages (T1 and T2; p<0.05). Among the immunohistochemical analytic markers, GLUT-1 had the highest positive staining rate (93.6%) compared to other markers. Based on univariable analysis, it was shown that the RI of high-level GLUT-1 expression was significantly higher than low-level GLUT-1 expression (p=0.01), and the RI of high-level p53 expression was slightly higher than low-level p53 expression (p=0.08). Multi-variate analysis to investigate a link between RI and clinicopathologic parameters of colorectal carcinoma showed that GLUT-1, p53, and T staging were independently connected with increased RIs (p<0.05, total) using backward selection methods. There was no significant statistical relationship between $SUV_{early}$ and $SUV{delayed}$ and clinicopathologic parameters in this study. Conclusion : The RIs obtained from preoperative colorectal cancers had a significant relationship to tumor size, T staging, GLUT-1, and p53, in contrast to $SUV_{early}$ or $SUV_{delayed}$ Compared with previous reports, our results showed that RI can better predict GLUT-1 expression than HK-2 and other immunohistochemical markers. This study demonstrated that the RI might have the potential to be applied as a prognostic marker in preoperative colorectal cancer.
