이 연구는 잡극 <심청왕후전>과 시나리오 <효녀 심청전>을 대상으로 하여 근대 시기에 최초로 이루어진 <심청전>의 극적 변용 양상을 살펴보고자 하였다. 이 두 작품에서 드러나는 개작 의식과 변용의 방향을 분석함으로써 1900년대 당시 <심청전> 향유의 기반을 알 수 있었다. 잡극과 영화시나리오로 만들어진 판소리문학 <심청전>은 근대라는 새로운 문화적 요구에 부응하면서 대중적 향유가 가능한 작품으로 만들고자 한 시도라 할 수 있다. 잡극 <심청왕후전>에서는 기존의 <심청전>에 대해 서사 전개의 논리적 인과성을 강화하고, 해학성은 약화하면서 초현실성은 부각하며, 노래를 통해 극적 표현을 시도하였다. 시나리오 <효녀 심청전>은 기존 <심청전>에는 없던 새로운 서사를 삽입하여 인물을 재창조하고, 이를 통해 해학성과 비극적 애상감이라는 양방향을 동시에 구현하고자 하였으며, 시간과 사건을 재배치하여 새로움을 추구하였다. 잡극 <심청왕후전>과 시나리오 <효녀 심청전>은 <심청전> 전승사에 있어서 최초의 극 양식으로의 변용과 시나리오로의 변용이라는 의의를 지니고 있다. 이들 작품은 판소리문학 <심청전>이 근대라는 새로운 문화에 적응한 모습을 보여주며, 시대를 달리하면서도 어떤 가치를 인정받고 지속적으로 향유되었는지를 말해준다.

This paper focuses on the analytical behavior of modular circular concrete-filled tubular (CFT) column with enhanced bracing details. To design a full-scale bridge pier of multiple circular concrete-filled tubes, numerical analysis was used to evaluate structural performance according to load directivity. In previous research (Ma et al. 2012, Shim et al. 2014), low cycle fatigue failure at bracing joints was observed, so enhanced bracing details to prevent premature failure are proposed in this analysis. The main purpose of this research is to investigate seismic performance for the diagonal direction load without premature failure at the joints when the structure reaches the ultimate load. The ABAQUS finite-element software is used to evaluate experimental performance. A quasi-static loading condition on a modular bridge pier is introduced to investigate structural performance. The results obtained from the analysis are evaluated by comparing with load-displacement responses from experiments. The concrete-filled tubes with enhanced bracing details showed higher energy dissipation capacity and proper performance without connection failure for a diagonal load.

Modular structures consist of standardized modules and their connections. A modular bridge pier is proposed to accelerate bridge construction. Multiple concrete-filled steel tubes (CFTs) using commercial steel tubes were chosen as the main members. Buckling restrained bracings and enhanced connection details were designed to prevent premature low-cycle fatigue failure upon cyclic loading. The pier had a height of 7.95 m, widths of 2.5 m and 2.0 m along the strong and weak axis, respectively. Cyclic tests were performed on the modular pier to investigate structural performance. Test results showed that four CFT columns reached yielding without a premature failure of the bracing connections. The ultimate capacity of the modular pier was reasonably estimated based on the plastic-hinge-analysis concept. The modular CFT pier with enhanced bracing showed improved displacement ductility without premature failure at the welding joints.

Autonomous mobile robots need SLAM (simultaneous localization and mapping) to look for the location and simultaneously to make the map around the location. In order to achieve visual SLAM, it is necessary to form an algorithm that detects and extracts feature points from camera images, and gets the camera pose and 3D points of the features. In this paper, we propose MPROSAC algorithm which combines MSAC and PROSAC, and compare the performance of optimization method and the filtering method for feature-based monocular visual SLAM. Sparse Bundle Adjustment (SBA) is used for the optimization method and the extended Kalman filter is used for the filtering method.

The gene ADH encoding NAD-dependent alcohol dehydrogenase from Bacillus stearothennophilus was cloned and overexpressed as a GST fusion protein at a high level in Escherichia coli. The expressed fusion protein was purified simply by glutathione affinity chromatography. GST fusion protein was then cleaved by thrombin, while soluble enzyme was further purified by glutathione affinity chromatography. The recombinant enzyme had the same elctrophoretic mobility as the native enzyme from Bacillus stearothennophilus. The recombinant enzyme catalyzed the oxidation of a number of alcohols and exhibited high activities towards secondary alcohols. The $K_m\;and\;V_{max}$ values of the recombinant enzyme for ethanol were 5.11 mM and 61.35 U/mg, respectively. Pyridine and imidazole notably inhibited the enzymatic activity. The activity of the recombinant enzyme optimally proceeded at pH 9.0 and $70^{\circ}C$. The midpoint of the temperature-stability curve for the recombinant enzyme was approximately $68^{\circ}C$, and the enzyme was not completely inactivated even at $85^{\circ}C$. The recombinant enzyme showed a high resistance towards denaturing agents (0.05% SDS, 0.1 M urea). Therefore, due to its stability and relatively broad substrate specificity, the recombinant enzyme could be utilized in bio-industrial processes and biosensors.

Oil seals will experience a small amplitude dynamic excitation due to the shaft eccentricity as well as out-of-roundness of the shaft. The direct integration method is selected to analyze the time domain response of the seal lip-shaft contact. The physical properties of rubber seal materials are experimentally analyzed. Effects of both frequency and temperature on the material stiffness behavior are investigated for the linear viscoelastic materials of the seal. Using the nonlinear transient model, a finite element analysis of the lip-shaft contact behaviors under dynamic conditions is presented as a function of the shaft eccentricity, the shaft interference and the garter spring stiffness. The FEM results based on the experimental data indicate that the increased rotating speed may produce the separation conditions. These results will be very useful in predicting the leakage of oil seals under dynamic conditions.

In this paper, the seismic performance of SRC piers for near fault motions was evaluated by shaking table tests on small scale models. Dead load of the superstructures was simulated by axial prestress at the center of the column section. A mass frame linked with steel bars was fabricated to include the effect of superstructure mass. Friction of the mass frame when it moves was minimized by special details and it was proved before tests. Five pier models with 400mm diameter were tested by increasing the acceleration of the near fault motion. Test results were discussed and compared with previous quasi-static tests.

운전하고 있으나 방사상계통 운전에 대한 정보공유가 미비하여 특정 계통조작시 정전으로 이어질 우려가 상존하고 있다. 본 논문에서는 방사상 계통과 환상계통을 자동 판단하여 계통조작시 정전사고로 이어질 수 있는 경우 사전 경고를 발생하여 정전조작을 미연에 방지할 수 있도록 하는 알고리즘을 개발하였다. 개발된 알고리즘은 SCADA와 미리 구축된 Rule Base를 이용하여 인근지역의 정보를 공유하고, 간단한 집합론을 이용한 수학적 연산작업을 통해 방사상계통인지 환상계통인지를 판단한다. SCADA 시뮬레이터를 통한 다양한 시험을 통해 개발된 알고리즘의 신뢰성을 검증하였으며 이를 구현한 방사상계통 자동판별시스템을 개발하여 실계통에 적용하였다.

As increasing interest for soot emission. etc in combustion systems, various studies are being carried out for the reduction and measurement techniques of soot. Especially, laser induced incandescence is the useful measurement technique which has distinguished spatial and temporal resolution for primary particle size, volume fraction and aggregated particle size etc. Time resolved laser induced incandescence is the technique for measuring primary particle size that is decided to solve the signal decay rate which is related to the cooling behavior of heated particle by pulsed laser. The cooling behavior of heated particle is able to represent the heat and mass transfer model which are involved constants of soot property for surround gas temperature on the our previous work. In this study, it is applied to the time-dependence thermodynamic properties for soot temperature instead of constants of soot property for surround gas temperature and compared two different model results.
