본 연구에서는 항만 및 어항시설의 내진설？준서에서 채택하고 있는 수정 Seed와 Idriss 방법을 이용하여 액상화 평가를 수행하고 액상화 가능지수(liquefaction potential index, LPI)와 등가 액상화 안전율(FE)을 이용하여 액상화 가능성에 대한 구역도를 작성하였다. 이 두결과가 유사한 것으로 나타나 등가 액상화 안전율의 적합성을 확인하였다 국내 연안의 두지역에 대하여 Hachinohe 지진기록과 Ofunato 지진기록을 이용한 액상화 가능성 구역도를 FE를 이용하여 작성한 후 비교한 결과 Hachinohe 지진기록에 의한 액상화 가능성 구역도가 더 과소평가되는 경향을 보이는 것으로 나타났다 또한 FE는 안전율의 형태로 표현되었기 때문에 구역도 작성과 해석에 편의 성을 제공하였다.

본 문에서는 선체 중앙부의 유한요소 모델링과 진동해석이 수행되었다. 횡부재와 종통부재가 만나 3차원적으로 연결되어 있는 선체구조는 복잡한 구조적 특성 때문에 모델링에 많은 노력이 필요하다. 선수, 선미부에 비해 비교적 부재간의 접속이 간단한 중앙평행부의 진동해석과 같은 경우에는 모델링 기법을 개발해 사용할 수도 있다. 중앙부 횡부재와 종통부재가 만나는 부분의 접속성과 형상표현을 위해 keypoint, super element(SE) 개념을 도입하였고 형성된 SE 들을 isoparametric mapping 기법을 접속된 3차원 부재용으로 개선하여 유한요소로 분할하였다. 진동해석용으로 형성된 선체중앙부 요소망을 ANSYS로 가시화하였고 자유진동해석을 수행하였다.

Modernism in architecture is a very complex and contradictory phenomena. So much so that it has been defined in various ways throughout the history, depending on one's position in the cultural and historical circumstances. It is thus necessary to map out the various concepts of modernism and their relationships in order to have a more comprehensive understanding of modern architecture. This paper attempts to define the various positions as functionalism, formalism and artistic avant-gardism, and to trace their history from the early twentieth century to the present. The change of the concept of modernism from functionalism to artistic avant-gardism seems a logical process in the history of western modem culture. The tendency of contemporary architecture to be more abstract and self referential artistic practice reflects the fragmentation of modern culture and the separation of art and technology. The validity of this position, of course, depends on how one evaluates the role of modern art in the situation of modern culture. It could be viewed either negatively or positively. However, this position is problematic in that it disregards the fundamental differences between architecture and other arts and distanced architecture farther from its material base. Given this historical perspective on the concept of modernism, modernism in Korea should not viewed simply identical to the western modernism, nor should western modernism be imported uncritically. The characteristics of her modernization and their differences from the west should be considered, along with the different status and role of architecture in korean modern society.

얼굴표정과 내적상태의 관계 모형을 수립하기 위한 기초 자료로서 얼굴표정과 내적상태의 대응 관계를 조사하였다. 심리적으로 최소유의미거리에 있는 두 내적상태는 서로 구별되는 얼굴표정으로 대응된다는 것을 확인함으로써 얼굴표정과 내적상태의 일대일 대응 관계가 성립한다는 것을 발견하였다. 얼굴표정 차원값과 내적상태 차원값의 관계 구조를 파악하기 위하여 중다희귀분석 및 정준상관분석을 실시한 결과, 쾌-불쾌는 입의 너비에 의해서 각성-수면은 눈과 입이 열린 정도에 의해서 얼굴표정에 민감하게 반영되는 것으로 나타났다. 얼굴표정 차원 열 두 개가 내적상태 차원상의 변화를 설명하는 정도는 50%내외였다. 선형모형이 이처럼 높은 예측력을 갖는다는 것은 이 두 변수 사이에 비교적 단순한 수리적 대응 구조가 존재한다는 것을 암시한다.

해충관리에 있어서 광범위한 지역에서 수집된 자료를 쉽게 요약하고 지도상에 나타내어 줄 수 있는 Computer Mapping System인 "MAPSYS"를 개발하였다. 개발된 Software System의 타당성을 검토해 본 결과 해충집단의 발생 및 예찰의 연구에 응용할 수 있음은 물론 작물과 이에 관련된 병해충의 분포 및 기상요소를 비롯한 각종 환경요소의 전국적인 분포를 나타내는데 사용하게 쓰일 수 있을 것으로 생각된다.

To reduce pollution, decrease the production of carbon dioxide, and to maintain a secure supply of energy, interest continues to grow in the area of renewable energy especially since there is a finite supply of cheap oil. Wind energy is one of the most viable options to consider and supply part of the energy needed to reduce dependence on foreign oil. However, it is difficult to predict the wind speed in an environment with many obstacles such as buildings and trees and getting accurate dimensions of those obstacles is difficult particularly on sloped mountainous terrain. In this study a drone was used to create a 3-D map of the campus of the Catholic University of Pusan. The dimensions and elevations for the 3-D map were used to make a model of the school campus in the CFD program Envi-met. Simulations were run for five different wind directions and 4 different elevations to find the location that would give the highest electrical output for a wind turbine. When considering all of these variables it was found that the optimal location was above the Student Union which had a 40% higher wind speed and could produce 274% more electrical power than the original wind speed.

This study aimed to analyze the prioritized area for the functional change of agricultural reservoir according to the rapid urbanization and social changes through the mapping method. Changwon-si, Gimhae-si,(콤마삽입) and Jinju-si in Gyeongnam province were selected as the study area, considering the results of land-use and cluster analysis. As the planning unit of management area, watershed was used and land coverage map from 1975 to 2015 were analyzed for changes of land use. The reduction ratio (%) of farmland was calculated for identifying the changes in 2013 compared to 1975. As a result, the reduction ratio was 11.9% for Changwon-si, 12.2% for Gimhae-si and 9.3% for Jinju-si, and the number of watershed having functionally reduced potential-area was relatively high in the proportion to the city size.

Geomagnetic field signals have potential for use in underwater navigation and geophysical surveys. To map underwater geomagnetic fields, we propose a method that exploits an autonomous surface vehicle. In our system, a magnetometer is rigidly attached to the vehicle and not towed by a cable, minimizing the system’s size and complexity but requiring a dedicated calibration procedure due to magnetic distortion caused by the vehicle. Conventional 2D methods can be employed for the calibration by assuming the horizontal movement of the magnetometer, whereas the proposed 3D approach can correct for horizontal misalignment of the sensor. Our method does not require a supporting crane system to rotate the vehicle, and calibrates and maps simultaneously by exploiting data obtained from field operation. The proposed method has been verified experimentally in inland waters, generating a magnetic field map of the test area that is of much higher resolution than the public magnetic field data.

가상현실은 현재 게임 산업에서 가장 주목하는 기술 중 하나다. 그럼에도 불구하고 가상현실 기술 자체가 극복해야 할 문제점과 시장가능성에 대한 의문으로 게임 산업에서 이에 대한 투자가 활발히 이루어지기 어려운 실정이다. 따라서 본 연구에서는 가상현실 게임 시장의 미래 가능성을 다각도로 타진해보고자 하였다. 이를 위하여 과거부터 현재까지 국내의 게임시장 발전 양상을 살펴보고, 시나리오네트워크매핑(SNM)을 활용하여 이해관계자 구조를 통한 미래예측을 시도하였다. 그 결과는 장·단기적 미래전망을 제시하고 이를 바탕으로 가상현실 게임 산업의 핵심이 될 이해관계자들에게 필요할 활동과 전략에 대한 시사점을 제시하였다는 데 공헌점이 있다.

Dual-color fluorescence in situ hybridization karyotype analysis was created using repetitive sequences including two types of rDNA repeats (45S and 5S rDNAs) and Arabidopsis-type telomere sequence repeats. The somatic metaphase cells of Carthamus tinctorius were observed as diploids (2n=2x=24). A symmetrical or slightly asymmetrical karyotype with seven pairs of metacentric and five pairs of submetacentric chromosomes was observed. The lengths of the somatic metaphase chromosomes ranged from 4.18 to 6.53 ㎛, with a total length of 60.71 ㎛. One locus of 45S rDNA was located on the pericentromeric regions of three pairs of chromosomes and the other pair was situated on the terminal regions of the short arms of a single pair of chromosomes. One locus of 5S rDNA was detected on the interstitial regions of the short arms of two pairs of chromosomes. Arabidopsis-type telomeric repeats were detected on the terminal regions of all pairs of chromosomes. Co-localization of loci between telomeric repeats and 45S rDNA was observed in a single pair of chromosomes. The results provide additional information for the existing physical mapping project of C. tinctorius and will also serve as a benchmark to a more intricate cytogenetic investigation of C. tinctorius and its related species.

The germline stem cells of the Drosophila ovary continuously produce eggs throughout the life- span. Intricate regulation of stemness and differentiation is critical to this continuous production. The translational regulator Nos is an intrinsic factor that is required for maintenance of stemness in germline stem cells. Nos expression is reduced in differentiating cells at the post-transcriptional level by diverse translational regulators. However, molecular mechanisms underlying Nos repression are not completely understood. Through three distinct protein-protein interaction experiments, we identified specific molecular interactions between translational regulators involved in Nos repression. Our findings suggest a model in which protein complexes assemble on the 3’ untranslated region of Nos mRNA in order to regulate Nos expression at the posttranscriptional level.
