In this paper, a design method for sequential circuit which is easy to have Built-in Self Test is kproposed using the functional advantages of multifunctional BILBO and LSSD. To achieve the hardware reduction, it is designed that a multifunctional BILBO has double operational functions of NLFSR and LFSR, when neccessary, and that test signal could be used as an input-output signal in the same line. By applying the proposed multifunctional BILBO to the sequential PLA, the test patterns and the additional circuit could be reduced in test operation and the propagation delay is vanished in normal operation, as we expected. Above them, the partitioned method for large scale sequential circuit is also suggested and it is observed that test patterns and additional circuit in them reduced by this method.

The purpose of this study is a presentation of long term strategies for hereafter hospital's remodeling and new constructions with grabbing in the characters of various spaces and ways of remodeling on wards which have been remodeled according to periods(the opening, before remodeling, after remodeling, new construction). The targets are three remodeled hospitals and four resent hospitals. And also the hospitals are divided as beds, additional hospital facilities, day room, doctor's and staff dining room, public space(corridor, core, duct) etc. The analEis of this study explains changes of wards through the characters expressed by remodeling on the specific functions (beds, additional hospital facilities, day room, doctor's and staff dining room, public space etc.) Following the research, the study has kept going to understanding of problems and limitations of improvement on remodeling wards. Finally, this researcher looked for suggestions on the planning of wards.

본 논문에서는 네트워크 환경에서의 외부침입에 대한 효율적인 탐지 구조를 제안하였다. 제안된 탐지구조에서는 각기 고유의 기능과 영역을 갖는 다수의 에이젼트들 사이에 블랙보드 구조를 갖는 협조 에이젼트(Coordination Agent)를 두고 Conflict Resolution 기능과 침입여부 확증 기능을 갖도록 함으로서 False Alarm을 감소시키도록 하였다. 시뮬레이션 결과 단순한 시스템 자원의 접근에도 기존 에이전트 방식은 침입이라는 판단을 내릴 수 있는 반면, 블랙보드 시스템은 에이젼트에 대한 적극적인 질의과정을 통해 최종적인 침입의 여부를 판정함으로써 침입 탐지 시스템의 신뢰도를 높일 수 있는 것으로 판단되었다.

본 연구에서는 보호, 여과, 차수기능을 갖는 부직포 지오텍스타일과 지오멤브레인의 응력완화거동을 각각 고찰하였다. "두 가지 지오신세틱스 제품의 응력완화거동을 해석하는데 "전이현상이론"이 적용되었다. 이들 지오신세틱스 제품의 응력완화거동에서 초기 및 후기 완화시간은 구성방정식으로부터 구하였다. 이들 지오신세틱스 제품의 초기완화거동은 부가변형률에 대한 의존성이 있으며, 특히 온도가 증가 할수록 증가하였다. 끝으로, 이들 지오신세틱스 제품의 초기 및 후기 완화시간은 부가변형률 및 온도가 커질수록 짧아졌으며, 완화시간 감소는 지오멤브레인보다 부직포 지오텍스타일의 경우가 더 큼을 알 수 있었다.

Flow characteristics of synthetic jet based flow supplying devices have been computationally investigated for different device shapes. Jet momentum was produced by the volume change of a cavity by two piezoelectric-driven diaphragms. The devices have additional flow path compared with the original synthetic jet actuator, and these flow path changes the flow characteristics of synthetic jet actuator. Four non-dimensional parameters, which were functions of the shapes of the additional flow path, were considered as the most critical parameters in jet performance. Comparative studies were conducted to compare volume flow rate and jet velocity. Computed results were solved by 2-D incompressible Navier-Stokes solver with k-w SST turbulence model. Detailed computations revealed that the additional flow path diminishes suction strength of the synthetic jet actuator. In addition, the cross section area of the flow path has more influence over the jet performances than the length of the flow path. Based on the computational results, the synthetic jet based flow supplying devices could be improved by applying suitable shape of the flow path.

보호, 여과 및 배수, 차수기능을 가진 부직포 지오텍스타일과 지오멤브레인의 응력완화거동을 각각 분석하였다. '전이현상 평형이론'이 이들 토목합성재료의 응력완화거동 해석에 적용되었다. 응력완화거동의 초기 및 후기완화시간을 구성방정식으로 부터 구하였다. 초기완화거동은 부가변형률에 좌우되며, 온도에 따라 빨라짐을 알 수 있었다. 끝으로, 이들 토목합성재료의 초기 및 후기완화시간은 부가변형률 및 온도에 따라 짧아졌다.

The notion of weak contraction in intuitionistic fuzzy metric space is well known and its study is well entrenched in the literature. This paper introduces the notion of (${\psi},{\alpha},{\beta}$)-weak contraction in intuitionistic fuzzy metric space. In this contrast, we prove certain coincidence point results in partially ordered intuitionistic fuzzy metric spaces for functions which satisfy a certain inequality involving three control functions. In the course of investigation, we found that by imposing some additional conditions on the mappings, coincidence point turns out to be a fixed point. Moreover, we establish a theorem as an application of our results.

A design expert system for the ship structural design is developed to support inexperienced designers. To establish the knowledge-base, an expert system development shell, Nexpert, is used. Knowledge is extracted from the rules of a classification society of ships, and also from an existing ship structural program that is being used by ship designers. This knowledge is systematized using the objectoriented concept. The design support system is constructed by adding additional functions which are required for the conventional engineering design work. Added functions are; calculation of longitudinal strength, database of existing ship designs, graphical user interface, and visualization of design results. It is observed that visualizing the relationships among the rules, which are activated to draw a certain design decision, is helpful. The system can easily be updated according to changes of the rule books of ship classification societies.

Messenger ribonucleoprotein particles (mRNPs) are used to transport mRNAs along neuronal dendrites to their site of translation. Staufen2 is an mRNA-binding protein expressed in the cell bodies and cellular processes of different brain cells. It is notably involved in the transport of dendritic mRNAs along microtubules. Its knockdown expression was shown to change spine morphology and impair synaptic functions. However, the identity of Staufen2-bound mRNAs in brain cells is still completely unknown. As a mean to identify these mRNAs, we immunoprecipitated Staufen2-containing mRNPs from embryonic rat brains and used a genome wide approach to identify Staufen2-associated mRNAs. The genome wide approach identified 1780 mRNAs in Staufen2-containing mRNPs that code for proteins involved in cellular processes such as post-translational protein modifications, RNA metabolism, intracellular transport and translation. These results represent an additional and important step in the characterization of Staufen2- mediated neuronal functions in rat brains.
