건설공사에서 사전 환경조사는 시공 전 현장 조사 서비스뿐만 아니라, 계획 및 설계에서도 매우 중요한 요소이다. USN과 결합된 지형공간정보의 적용은 사전에 건설 현장의 진행 단계마다 조사 및 연구에 매우 경제적인 방법이기 때문에 건설 환경 계획 및 기본 설계의 건설을 위하여 매우 중요한 역할을 수행하여 불필요한 시행착오를 줄일 수 있다. 본 연구에서는 공간위치를 기반으로 환경 센서와 무선통신 기술을 융합하여 건설현장을 디지털 공간정보 환경으로 전환하고, 현장에 설치된 무선의 소형 환경 센서를 이용하여 각 유비쿼터스 센서에서 측정된 환경 데이터를 싱크 센서가 데이터 수집 처리하고 초소형 Tiny OS 기반의 PC 출력 이미지를 전송하는 방식으로 현재 진행되고 있는 건설 현장의 여러 환경정보를 3차원 지형공간에서 실시간으로 그 환경변화를 모니터링 할 수 있도록 하였다.

FPGA(Field Programmable Gate Array) 디바이스는 회로의 개발 기간을 단축할 수 있으며, 낮은 비용으로 자체적인 회로를 구현할 수 있다는 장점이 있다. FPGA 중에서도 SRAM기술을 사용하는 FPGA는 게이트의 집적도가 높아 복잡한 회로의 구현이 가능하고, 구현한 회로를 동적으로 변경할 수 있는 특징이 있어, 최근 인공위성의 탑재컴퓨터에 그 사용빈도가 증가하고 있는 추세다. 그러나, SRAM 기반 FPGA는 우주 방사선 입자들에 의한 오류 현상인 단일사건오류에 취약하여, 우주에서 사용할 때에는 이를 검출하고, 정정할 수 있는 회로를 탑재해야 한다. 이 논문에서는 FPGA의 내부 모듈 중에서 SEU에 가장 취약한 재구성 메모리를 보호하는 제어기를 설계하였다. 제어기는 SEU에 강한 Anti-Fuse방식의 FPGA에 구현하였으며, 실제 회로 구현 후, 방사능 시험을 수행한 결과, 본 연구에서 제안한 재구성 메모리 보호 제어기를 기존의 TMR회로와 함께 사용하면, 보다 우수한 고장허용성을 갖는 것을 입증하였다.

Since WWII and the Korean War, Korean modern fashion has been americanized by claiming, displacing with, and fusing with the traits of American fashion. The purpose of this study is to observe and analyze the traits of Americanization in Korean fashion, focusing on the designs of Nora Noh fashion from the 1950s to the 1980s. Nora Noh (1928- ), one of the first Korean fashion designers, who launched the first fashion show in 1956, introduced ready-made dresses to Korean fashion industry in 1963 for the first time, and later in the 1970s and the 1980s, exported Korean-made fashions to the U.S. market. For such purpose, this study first provides the theoretical backgrounds of Americanization in Korean fashion history and then conducts a case study by analyzing photographic materials. In case of Nora Noh fashion, the traits of Americanization can be defined as functionality, popularity, and hybrid. (1)Functionality in Americanized Korean fashion was expressed through simplicity, practicality, and usefulness. Noh's "homewear" style and exported silk dresses are the examples of the functionality. (2)Popularity was shown in kitsch images of materialistic and consumer culture. It was expressed in ready-made dresses and trendy styles of mini skrits and bell-bottom pants. (3)Hybrids of various multi-culture exist in American culture and fashion. In Noh's designs, traditional materials and the print patterns inspired from traditional motifs were used to add Korean nuances in Americanized fashion.

애니메이션은 전체적인 서사구조 속에서 캐릭터의 미적특징과 행동이 융합되어 표현되며, 이와 같은 캐릭터의 창조는 그것을 탄생하게 한 사회문화적 배경과 극적 구조 속에서 심리학적 접근이 필요하다. 본 연구는 애니메이션 캐릭터 창조에 있어 보다 현실성에 바탕을 둔 캐릭터를 형상화합과 동시에 개성적이고 독창적인 캐릭터와 네러티브 개발의 필요에 의해 시작되었다. 본 논문에서는 미국 정신의학회의 DSM-IV 정신장애와 진단 및 통계편람 을 통해 애니메이션 캐릭터의 성격장애를 분석해 본 결과 캐릭터의 성격유형은 일반적인 경향보다는 과장되게 표현됨으로써 극적인 동기유발과 극에 있어서 개연성을 위한 도구로 쓰였다. 또한 애니메이션 캐릭터에 성격장애와 같은 증세를 성격에 부여받음으로 네러티브 전개에 있어 변화를 가져 왔으며, 애니메이션 캐릭터가 비록 성격장애는 아닐지라도, 성격장애와 같은 기질이 과장 혹은 증폭되어 나타나고 있음을 알 수 있다.

The purpose of this study is to find out how to use emotional activity rate in sentence. The aim is to estimate the Emotion-Codon status of emotion-DNA wiggling as well as the sequence of codons in which amino acids of human body are spread. It is as if the amino acids are translated from the DNA of the human body, and the emotions that cooperate with each other are diversified and refined. Through these attempts, we anticipate the change of emotions by literary works and present the direction of the synapse working and the direction of the encoding. Therefore, this study analyzed the emotional activity of Rated Emotion-Codon, which works as Rated Sijo. At this time, the emotional change in the human body, in which the sentence is more clearly pronounced, is predicted and detected. This result shows how emotions can activate the human body. This state of activation is an indicator of how much the sentence pushes the physiological action of the human body. It is judged that Codon is constructed precisely for the activation of the rated Sijo additive definition by this index. Our result is evidenced by the fact that three sentences of Rated Sijo show an array with the same rating as the Rated Codon's, The first sentence fuses with the sentiment between the second sentence and the third sentence of Rated Sijo. The emotional symbols between the sentence symbols "A, U, J, L" in the first base of the Codon table and the sentences fusing between the sentences of the first sentence and the third sentence are "A, U, J, L". The emotional symbols between the sentences flowing in the second base of the Codon table and between the sentences of the first sentence and the second sentence are structured in the third base of the Codon table as "A, U, J, L". The Rated Sijo, which is resiliently and precisely assigned to the human body's Rated Emotion-Codon, will require a rich experience in our Rated Life.

This paper presents a sensor fusion method based on indirect Kalman filter(IKF) for error compensation of low-cost inertial sensors and its application to the determination of attitude and position of small flying robots. First, the analysis of the measurement error characteristics to zero input is performed, focusing on the bias due to the temperature variation, to derive a simple nonlinear bias model of low-cost inertial sensors. Moreover, from the experimental results that the coefficients of this bias model possess non-deterministic (stochastic) uncertainties, the bias of low-cost inertial sensors is characterized as consisting of both deterministic and stochastic bias terms. Then, IKF is derived to improve long term stability dominated by the stochastic bias error, fusing low-cost inertial sensor measurements compensated by the deterministic bias model with non-inertial sensor measurement. In addition, in case of using intermittent non-inertial sensor measurements due to the unreliable data link, the upper and lower bounds of the state estimation error covariance matrix of discrete-time IKF are analyzed by solving stochastic algebraic Riccati equation and it is shown that they are dependant on the throughput of the data link and sampling period. To evaluate the performance of proposed method, experimental results of IKF for the attitude determination of a small flying robot are presented in comparison with that of extended Kaman filter which compensates only deterministic bias error model.

The objectives of this study are to define the fundamental notions of collaboration in design field. The results of this study are summarized as follows: Firstly, collaboration means a cooperative work which are cooperatively done by collabarator and collaboratee on the equal status within a certain period of time, based on core ability of each of them. This cooperative work is presented with a visual image based on the identity of participants, and it creates an added value. Collaboration is different from convergence and hybrid in the methodological aspects and from brand alliance and strategic alliance in the aspects of the subject of project. Secondly, collaboration has been developing through step of using the specific ability, step of sharing each core abilities, and step of fusing their identities, in a view of the sphere of cooperative work and the intimate relations in reciprocity. Thirdly, according to strategic purpose, collaboration can be classified into value ascending collaboration, image changing collaboration, business-field extension collaboration, and event collaboration.

Due to the significant increase in the use of autonomous car technology, it is essential to integrate this technology with high-precision digital map data containing more precise and accurate roadway information, as compared to existing conventional map resources, to ensure the safety of self-driving operations. While existing map technologies may assist vehicles in identifying their locations via Global Positioning System, it is however difficult to update the environmental changes of roadways in these maps. Roadway vision algorithms can be useful for building autonomous vehicles that can avoid accidents and detect real-time location changes. We incorporate a hybrid architectural design that combines unsupervised classification of vision data with supervised joint fusion classification to achieve a better noise-resistant algorithm. We identify, via a deep learning approach, an intelligent hybrid fusion algorithm for fusing multimodal vision feature data for roadway classifications and characterize its improvement in accuracy over unsupervised identifications using image processing and supervised vision classifiers. We analyzed over 93,000 vision frame data collected from a test vehicle in real roadways. The performance indicators of the proposed hybrid fusion algorithm are successfully evaluated for the generation of roadway digital maps for autonomous vehicles, with a recall of 0.94, precision of 0.96, and accuracy of 0.92.

The equine chorionic gonadotropin (eCG) subunits $\alpha$ and ${\beta}$ are transcribed from different genes and associate noncovalently to form the bioactive eCG heterodimer. Dimerization is rate limiting for eCG secretion, and dissociation leads to hormone inactivation. The correct conformation of the heterodimer is alto important for efficient secretion, hormone-specific post-translational modifications, receptor binding and signal transduction. To determine whether ${\alpha}$ and ${\beta}$ subunits can be synthesized as a single polypeptide chain (tethered-eCG) and also display biological activity, the tethered-eCG molecule by fusing the carboxyl terminus of the eCG ${\beta}$-subunit to the amino terminus of the af-subunit was construe-ted and transfected into chinese hamster ovary (CHO-Kl) cells. LH- and FSH-like activities were assayed in terms of testosterone production and aromatase activity in primary cultured rat Leydig cells and granulosa cells, respectively. The tethered-eCG was efficiently secreted and showed similar LH-like activity to the dimeric eCG ${\alpha}$/${\beta}$ and native eCG. FSH-like activity of the tethered-eCG was also shown similarly in comparison with the native and wild type eCG ${\alpha}$/${\beta}$. Our data for the first time suggest that the tethered-eCG can be expressed efficiently and the produced product by the CHO-K1 cells is fully LH- and FSH-like activities in rat in vitro bioassay system. Our results also suggest that this molecular can imply particular models of FSH-like activity not LH-like activity in the eCG. Taken together, these data indicate that the constructs of tethered molecule will be useful in the study of mutants that affect subunit association and/or secretion.
