본 연구는 다원화된 현대건축에서 나타나는 현상의 하나인 단일체적(monolithic) 표현 성향의 특성에 관한 것이다. 다양한 건축적 표현 중에서 단일체 건축은 형태적 산만함이나 분열, 이론에 치중한 형태적 복합성의 난해함을 대치하려는 의도로 해석되고, 현시대의 불안정성, 불확정성, 유동성 등이 강조되는 아방가르드적인 건축이론이나 작품경향에 반해 건축의 위상과 자율성 확립을 통한 반발이기도 하다. 이런 단일체 건축은 단순하고 경제적인 구조를 빈틈없는 외피로 감싼 형태적 엄격함을 보여주면서 인식이 용이한 이미지를 구축함으로써 독자적 아이덴티티를 갖춘 형태의 자립형 건축이라 할 수 있다. 외관의 추상적 형태를 이용해 형태묘사적인 아이덴티티를 구축하거나, 크기나 스케일을 과장함으로써 존재감을 강화시키기도 하며, 색, 재료, 마감, 단면형태 등을 이용하여 내부공간과 외부공간을 중재하는 표피를 전략적으로 탐색하기도 한다. 이런 단일체 건축은 오늘날의 다중적이고 불확정적인 상황에서 건축적 아이덴티터를 확립하기 위한 노력의 일환으로 받아들이는 것이 합당할 것이다.

We present a monolithic semi-implicit algorithm for solving fluid-structure interaction problem at small structural displacements. The algorithm uses one global mesh for the fluid-structure domain obtained by gluing the fluid and structure meshes which are matching on the interface. The continuity of velocity at the interface is automatically satisfied and the continuity of stress does not appear explicitly in the global weak form due to the action and reaction principle. At each time step, we have to solve a monolithic system of unknowns velocity and pressure defined on the global fluid-structure domain. Numerical results are presented.

SCR (Selective Catalytic Reduction) on DPF (Diesel Particulate Filter) is a multi-functional after-treatment device which integrates soot filtration and DeNOx function into a single can. Because of its advantage in package and cost, the SCR on DPF is considered as a potential candidate for future application. It inherently employes wall flow type monolithic reactor so ash included in exhaust gas may deposit inside the inlet channel of this device. This study is intended to identify the impact of ash deposit on SCR reaction under wall flow type monolithic reactor. Simulation approach is used so relevant species transport equations for wall flow type monolith is derived. These equations can be solved together with momentum conservation equations and give solution for conversion performance. Both ash deposit and clean catalyst case are simulated and comparison of these two cases gives an insight for the impact of ash deposit on conversion performance. Ash deposit can be classified as ash layer and ash plug. and impact of ash deposit is described along with different morphology of ash deposit.

Several companies have migrated their existing monolithic web applications to microservice architectures. Consequently, research on the identification of microservices from monolithic web applications has been conducted. Meanwhile, the use-case model plays a crucial role in outlining the system's functionalities at a high level of abstraction, and studies have been conducted to identify microservices by utilizing this model. However, previous studies on microservice identification utilizing use-cases did not consider the components executed in the presentation layer. Unlike existing approaches, this paper proposes a technique that considers all three layers of web applications (presentation, business logic, and data access layers). Initially, the components used in the three layers of a web application are extracted by executing all the scenarios that constitute its use-cases. Thereafter, the usage rate of each component is determined for each use-case and the component is allocated to the use-case with the highest rate. Then, each use-case is realized as a microservice. To verify the proposed approach, microservice identification is performed using open-source web applications.

We demonstrated the combined applications of online protein digestion using trypsin immobilized enzyme reactor (IMER) and dual tandem mass spectrometry with collisionally activated dissociation (CAD) and electron transfer dissociation (ETD) for tryptic peptides eluted through the trypsin-IMER. For the trypsin-IMER, the organic and inorganic hybrid monolithic material was used. By employing the trypsin-IMER, the long digestion time could be saved with little or no sacrifice of the digestion efficiency, which was demonstrated for standard protein samples. For three model proteins (cytochrome c, carbonic anhydrase, and bovine serum albumin), the tryptic peptides digested by the IMER were analyzed using LC-MS/MS with the dual application of CAD and ETD. As previously shown by others, the dual application of CAD and ETD increased the sequence coverage in comparison with CAD application only. In particular, ETD was very useful for the analysis of highly-protontated peptide cations, e.g., ${\geq}3+$. The combination approach provided the advantages of both trypsin-IMER and CAD/ETD dual tandem mass spectrometry applications, which are rapid digestion (i.e., 10 min), good digestion efficiency, online coupling of trypsin-IMER and liquid chromatography, and high sequence coverage.

We describe an optimal alignment method for improving accuracy of dynamic spectroscopic polarimeter based on monolithic polarizing interferometer. The dynamic spectroscopic polarimeter enables real-time measurements of spectral ellipsometric parameters by using a spectral carrier frequency concept. However, the non-polarizing beam splitter used in the monolithic polarizing interferometer cannot maintain the polarization state perfectly due to phase retardation caused by optical anisotropic characteristics of the non-polarizing beam splitter, resulting in degraded measurement accuracy. The effect of the beam splitter can be minimized through optimal alignment of the polarizers used in the polarizing interferometer and the analyzer. We demonstrate how much the proposed alignment method can enhance the measurement accuracy by comparing with previous alignment approach.

본 연구에서는 효율적인 광원과 광도파로간의 결합방법으로서 많은 연구가 진행중인 monolithic laser-waveguide coupler 특성해석에 beam propagation method를 도입하여 기존의 방법과 비교검토 한 결과 타당성을 입증할 수 있었으며, 또한 결합효율을 향상시키기 위하여 taper 구조를 가진 monlithic laser-waveguide coupler를 제시하였다. monolithic laser-waveguide coupler는 능동소자인 laser의 특성과 수동소자인 waveguide의 특성을 동시에 가지고 있으므로 고려하여야할 요소가 매우 많고, 또 각 요소들의 변화에 따라 결합기의 성능이 크게 좌우되므로 그 특성 연구가 많은 어려움이 있었다. 때문에 본 연구에서는 방향성 결합기를 사용한 모델을 해석하는 방법으로 기존의 coupled mode 이론을 사용할 수도 있겠으나, 본 연구에서와 같이 많은 변수를 가지는 경우의 해석에는 적용하기 어렵다는 단점 때문에 beam propagation method를 사용한 해석을 시도하였다. 또한 해석에 있어서 가장 기본이 되는 초기전개의 계산에서도 종래의 연구에서와 달리 근사식을 이용해 전계를 계산하지 않고, 주어진 구조에 대하여 직접 finite difference method를 적용하여 초기전계를 구하였다. 이러한 새로운 시도들이 가지는 잇점을 방법과 비교하여 알아 보았으며, 새로운 방법의 적용을 통하여 보다 많은 변수를 고려하여 monolithic laser-waveguide coupler의 특성을 연구할 수 있었다. 이러한 과정을 통하여 결합기의 특성을 파악하고 그 결과로 monolothic laser-waveguide coupler의 특성중 가장 중요한 결합특성을 향상 시키기 위해서 taper영역을 가지는 monolothic laser-waveguide coupler를 제안하였다. 본 연구에서 제안한 구조에 대하여 특성을 조사해본 결과 79%정도의 좋은 결합효율을 얻을 수 있었다.

This article examines China's political characteristics from a cultural perspective. First, it demonstrates the usefulness of the semiotic model through comparative analysis of various political and cultural research methods. Next, this model is used to analyze the representative religions of China, Confucianism and Taoism. Lastly, it analyzes the influence of the cultural codes derived through this on Chinese politics. In conclusion, China has a monolithic cultural code that seeks harmony with transcendental order centered on secular order. It is analyzed that the cultural code of this characteristic had an influence on the orientations of non-rationalization and realism.

An analytical method has been developed for the rapid determination of perfluorinated compounds (PFCs) in human serum samples. The extraction and purification of PFCs from human serum were performed by the modified method of previous report. Ten PFCs were rapidly separated within 3.3 min by C18-monolithic column liquid chromatography (LC) and detected by electrospray ionization (ESI) tandem mass spectrometry (MS/MS) in negative ion mode. The runtime of PFCs on monolithic column LC was up to 4-fold faster than that on conventional column LC. The effect of triethylamine (TEA) to the mobile phase has investigated on the overall MS detection sensitivity of PFCs in ESI ionization. Quantification was performed by LC-MS/MS in multiple-ion reaction monitoring (MRM) mode, using $^{13}C$-labeled internal standards. Method validation was performed to determine recovery, linearity, precision, and limits of quantification, followed by, the analysis of a standard reference material (SRM 1957 from NIST). The overall recoveries ranged between 81.5 and 106.3% with RSDs of 3.4 to 16.2% for the entire procedure. The calibration range extended from 0.33 to 50 $ng\;mL^{-1}$, with a correlation coefficient ($R^2$) greater than 0.995 and the limits of quantification with 0.08 to 0.46 $ng\;mL^{-1}$. This approach can be used for rapid and sensitive quantitative analysis of 10 PFCs in human serum with high performance and accuracy.
