The finishing method of concrete floor using automatic surface finisher is one of new technologies in concrete floor construction. Multipurpose Floor Level Joint(MFLJ) works not only as expansion joint controlling shrinkage and expansion of concrete but also as a guide for automatic surface finishing. The purpose of this study is to evaluate the deformation absorbing capacity of the floor level joint. Fourteen specimens are designed and tested by inducing gradually increasing rotation in the joint. In the test, it is purposed to examine quantitatively the expansion and shrinkage capacity of concrete due to temperature gradient. Test result shows that MFLJ has sufficient deformation capacity required to act as expansion joint.

본 논문은 평면상에 주어진 자료점의 집합 P로부터 질의 집합 Q에 대해 skyline을 성질을 만족하는 Q의 부분집합을 찾는 알고리즘을 제시한다. 이 때 P의 점들 간의 우위는 Q의 점에서의 거리를 이용하여 판단하는데 이 논문에서는 두 점간의 거리를 L₁거리로 정의한다. 이와 같은 환경 하에서 P ≥ Q 라고 가정할 때 우리는 O( log ) 시간에 모든 skyline을 찾는 알고리즘을 제시하였다.
L1 메트릭에서의 이동 질의점에 대한 skyline 계산
손완빈(Wanbin Son),황승원(Seung-won Hwang),안희갑(Hee-Kap Ahn) 한국정보과학회 2012 한국정보과학회 학술발표논문집 Vol.39 No.1A
본 논문에서는 L₁ 메트릭을 사용하는 평면상에 주어진 자료점의 집합 P로부터 질의점의 집합 Q에 대해 skyline이 되는 점들을 계산하는 문제를 다룬다. L₁거리는 도로망이 잘 발달된 도시 내의 이동 시간을 근사화해 주는 것으로 알려져 있다. 이 문제에서 각각의 질의점은 수직 또는 수평 방향으로 단위속도로 움직인다고 가정한다. 본 논문에서는 시간 0에서 t₁사이에 움직이는 질의점들에 대해서 skyline의 변화를 모두 계산하는 알고리즘을 제시한다. 또한 이 알고리즘이 O(│P│²│Q│) 시간에 모든 skyline을 계산 가능함을 보인다.

본 논문은 Data mining에서 선호도 분석 등에 사용되는 Skyline Query[2] 중 자료의 속성에 spatial한 성질이 있을 때 사용할 수 있는 Spatial Skyline Query[3] 문제에 대해 연구한다. 우선 Spatial Skyline 집합을 추출하기 위한 기존의 알고리즘의 문제점을 짚어보고 보다 개선된 알고리즘을 제시한다. 또한 전체 Spatial Skyline 집합이 아닌 그 중 더 의미 있을 수 있는 부분 집합을 좀 더 빠른 시간 복잡도에 구하는 방법 또한 제시한다.
中世 基督敎 身體觀과 聖書 身體觀의 文獻的 考察 : 禁慾主意를 中心으로 Centering around the Asceticism

The generalized record about the history of Medieval Physical Education is "Due to the Asceticism of Medieval Chreistianity, Physical Education faced its dark age.". I considered the cause of that record hstorically, and also considered about the Biblical view of Asceticism by literature. Therefore it can be said that the purpose of this paper is to reinvestigate the physical view under today's Christian culture through the past history. The main stream of Medieval history was the fusion of Hellenism and Hebraism. Asceticism of Medieval Christianity was connected with these two main streams. So I considered the historical background of Asceticism influenced by these two main streams and its development process. Medieval Christianity and Biblical viewpoint of the body were all Christian points of view. But, from the viewpoint of Physical Education, Body-and-Soul Dualistic Asceticism, in which the body was always considered as incompatible with soul, and the body was the target of ascetic practice of soul-purification, was considered as a negative viewpoint, and Biblical human understanding as an organic unity was considered as an affirmative veiwpoint. In the very Middle Age, Asceticism was strongly highlighted as a form of Medieval Christainity. Therefore Physical Eucation faced its dark age. The reasons for that are: First, the Greek philosopher's Body-and-Soul Dualism and the Soicism had an influence on the Medieval Christianity throught Ancient Rome. Second, in Rome, which is under the polytheim culture, there remained some papgan elements, and the spirtual and moral level was lowered. Therefore, true Christians went into the abbey. Aecetic concept in the abbey had a great influence on the Medieval society. Third, in the process of integration of Christian concept of Asceticism and Greek concept of Asceticism by the Christian priests, a transformed Asceticism began to appear in Medieval Christianity. The viewpoints on the Asceticism based on the Biblical view of the body were: First, Chirstian Asceticism premised the greatness of Creation within thephysical and biological order. Second, it didn't accept the Asceticism which despised the body on the basis of Body-and-Soul Dualism, but Accepted the human who was a whole person as an organic unity. Third, the Bible had a command of Love, rather than a strict discipline(an ascetic from). In conclusion, the Asceticism of Medieval Christianity was the peculiar product of that age. On the other hand, the Bible, by being opposed to the Asceticism of Medieval Christianity, and by acceptign the human being as a whole person, emphasisd on the importance of human being physically as well as spiirtually. This has a great significance on the Physical Education as an education through a physical activity.
