Manhattan프로젝트 보고서이기도 한 Katz와 Rabinowitch의 'The Chemistry of Uranium'에서는 우라늄발생 분광스펙트럼에 대한 흥미있는 사진을 게재하였는데 이 사진은 동위체가 빛에 의해 분리될 가능성을 시사하고 있는 것으로 평가되었다. 다음 내용은 최근 각국이 개발에 참여하고 있는 레이저를 이용한 동위체분리법의 소개이다.

The human head is identified as the body region most frequently involved in life-threatening injuries. Extensive research based on experimental, analytical and numerical methods has sought to quantify the response of the human head to blunt impact in an attempt to explain the likely injury process. Blunt head impact arising from vehicular collisions, sporting injuries, and falls leads to relative motion between the brain and skull and an increase in contact and shear stresses in the meningeal region, thereby leading to traumatic brain injuries. In this paper the properties and material modeling of the subarachnoid space (SAS) as it relates to Traumatic Brain Injuries (TBI) is investigated. This was accomplished using a simplified local model and a validated 3D finite element model. First the material modeling of the trabeculae in the Subarachnoid Space (SAS) was investigated and validated, then the validated material property was used in a 3D head model. In addition, the strain in the brain due to an impact was investigated. From this work it was determined that the material property of the SAS is approximately E = 1150 Pa and that the strain in the brain, and thus the severity of TBI, is proportional to the applied impact velocity and is approximately a quadratic function. This study reveals that the choice of material behavior and properties of the SAS are significant factors in determining the strain in the brain and therefore the understanding of different types of head/brain injuries.

본 논문은 도심을 촬영한 실내, 실외의 영상은 대부분 직육면체를 이룬다는 "Manhattan World" 가정을 기반으로 한 소실점의 직교성을 이용한 구조적인 소실점 검출 방법을 제안한다. 소실점들이 서로 직교하는 특징은 3개의 소실점 중 검출되지 않은 소실점을 추론하는데 매우 유용하게 사용될 수 있으며 소실점이 근접하여 검출되는 경우를 방지할 수 있다. 본 논문에서는 통계적인 접근을 통해 수직 소실점을 검출하고 구조적인 방법으로 수평, 전방 소실점을 검출하였다. 실험결과에서는 제안된 방법이 기존 방법과 비교하여 소실점 검출 정확도가 향상됨을 보인다.

Inspired by the success of the High-line project in New York, The Seoul Metropolitan Government launched a project to convert an overpass near Seoul station into a pedestrian park. Seoullo 7017 went through instant success after its opening in May 2017; however, there is a continuous controversy over its long-term impact as shown in the exemplary cases like the High-line project. This study aims for quantitative investigation through the comparative analysis between Seoullo 7017 and the High-Line in the perspectives of spatial configuration. Space Syntax was chosen as the analysis method for this research. Integration (3) in Space Syntax is known to have a high correlation with pedestrian volume; thus, by using this method, spatial structure was analyzed by comparing the statistically verified results of changes in the spatial structure of the Highline with those in Seoul. The results indicated that the influence of Seoullo 7017 was less than that of the High-line in terms of spatial configuration. The reason for this difference is spatial configuration between Manhattan and Seoul. The High-line is located in Manhattan which has an urban grid structure, whereas Seoul has non-geometric urban structure, the neighborhood unit in Korea. Also the center of the overpass isn't connected well with its surroundings.

본 연구는 서울보다 일찍이 성장하여 도심 문제해결과 도시 생태계 회복을 위해 주거 공간의 제공에 노력을 기울여온 뉴욕 맨해튼 도심과의 현황의 비교를 통해 서울 역사도심의 도시생태계 불균형의 문제점과 그에 따른 주거 기능 회복의 필요성을 제시하는 데에 목적을 가지고 있다. 주거 공간의 총량, 주거용도 건축물 유형별 특성, 주거용도 건축물의 분포 분석을 통해 도심 상업용도지역 내 주거현황을 조사하였다. 이를 통해, 서울 역사도심은 대부분의 공간이 상업용도에 편향되어 있으며, 도심주거에 적합한 중고밀도의 복합용도 건축물이 맨해튼 도심에 비해 현저히 부족함을 알 수 있었다. 또한 서울 역사도심은 복합용도 건축물이 대상지의 외곽에 인접하여 위치함을 알 수 있었다. 결론적으로 서울 역사도심은 도시 생태계 조성을 위한 적절한 주거 공간을 제공하지 못하고 있으며, 주거 기능 회복을 위한 방안 마련이 필요하다.

Some discussions are made about practices which take places in some aspects of instructions from the viewpoints of traditional and reform based instruction. This kind of discussion is needed to be done, because there is no evidences to show that reform based instruction is mainly implemented among teachers even through reform based instruction has continued to be stressed since the 7th national curriculum was released. Some suggestions was made for consideration of further deep discussions based on the practices discussed earlier.

This paper delves into the recent 'paintings' of African-American artist David Hammons, which combine rubbish-like plastic wraps with the abstract-expressionist style paintings. In straddling between rubbish and art object, his works tend to blur the boundary drawn between two opposite categories in value, art and garbage, provoking the sophisticated taste of Upper-East-side white community in Manhattan, New York. Choosing the venue of his exhibition at a commercial gallery, Hammons's creative efforts is also a critique of what can be seen as the dominance of abstract expressionism and white elitism in American art history. The artist is known for his use of unconventional materials in art making such as black hair, barbecue bones, and elephant droppings, ones that are often associated with African-American experiences in all different levels. Since his debut in the art scene in the 1970s, Hammons has pursued the view of art-making as a medium for provoking contentious issues of racial relations in the States. On the other hand, the reception of Hammons's work as African-American art can be potentially quite limiting, overlooking as it does multi-faceted meanings of his art practice. His unconventional approach to art often took him outside art galleries and museums, where he was seen using a variety of common materials for site-specific installations and performances. Staged in different parts of Manhattan, these acts of art making traverse seemingly opposite communities and cultures, often blurring their boundaries. Hammons's artistic practice can label him what Abdul Jan Mohamed calls "specular border intellectual", revealing as it does the symbiosis of binary oppositions that is basic to the experience of communnal living.
