The tendency of formalization in Contemporary Architecture deeply relies on the thought of Western Philosophy, which emphasizes the art of image perceived visually but ignores the body and perception of a human beig who uses the architecture and lives in it. On the contrary, Merleau-Ponty asserted long time ago that the world and the body are inseparably related to each other. The phenomenology is important in Architecture, since the center of thought should be taken back to the human body if a artistic meaning can be obtained by Architecture. From this point of view, the meaning of Contemporary Architecture can be renewed by the phenomenological idea of Merleau-Ponty as a means of expanding thought that overcomes the limit of formalization in Contemporary Architecture. This research aims to ream from Steven Holl's work, and show the Architectural elements that are used for preceptual experience of phenomenon and the function of those element sin Architectural space of his works. The result of study on about the phenomenal light and water in Architectural space of Steven Holl is as follows; First, in perceptional experience of phenomenon, time is an important element, which is successive and make a field that cause perceptional experience. Second, light, as a phenomenological element, acted as a means of expressing the comparison and change of light and shadow in Architectural space and showing the change of color by the diversity of time in inner space. Third, water, as a phenomenal lens, not only acted functional but also functioned as an element of sensual experience in Architectural space. It acted as an image containing time, space, just like a mirror that reflect the environment.

심정지(Cardiac arrest)는 원인과 관계없이 심장의 박동이 정지되어 발생하는 일련의 상태를 말한다. 심장질환에 의한 심정지는 매년 우리나라 3대 사망원인에 포함되며 예측이 불가하다. 심정지 발생시 환자의 생명을 구하기 위한 유일한방법 중 하나는 심폐소생술이며 이 술기를 통하여 순환을 유지시킬 수 있다. 시각으로 받아들여진 정보는 시신경을 통하여 뇌로 전달되며, 그중 거울은 자신의 움직임과 자신의 형태를 볼 수 있게 하고, 교정과 분석이 가능하여 다양하게 활용 할 수 있다. 이에 거울을 활용한 시각적 정보에 따른 가슴압박의 질을 비교하였다. 연구결과 거울 사용에 따라 가슴압박의 평균 깊이가 유의한 차이가 있었고($48.93{\pm}6.76$, $53.86{\pm}4.56$, <0.001), 압박 대 이완 비율에도 차이를 보였다($0.87{\pm}0.13$, $0.96{\pm}0.10$, <0.002). 또한 자세를 의식하는 정도에서도 유의한 차이를 보였다($4.93{\pm}0.85$, $8.14{\pm}1.38$, <0.001).

Silicon can be reactive ion etched (RIE) either isotropically or anisotropically. In this paper, a new micromachining technology combining these two etching characteristics is proposed. In the proposed method, the fabrication steps are as follows. First. a polysilicon layer, which is used as the bottom electrode, is deposited on the silicon wafer and patterned. Then the silicon substrate is etched anisotropically to a few micrometer depth that forms a cavity. Then an PECVD oxide layer is deposited to passivate the cavity side walls. The oxide layers at the top and bottom faces are removed while the passivation layers of the side walls are left. Then the substrate is etched again but in an isotropic etch condition to form a round trench with a larger radius than the anisotropic cavity. Then a sacrificial PECVD oxide layer is deposited and patterned. Then a polysilicon structural layer is deposited and patterned. This polysilicon layer forms a pivot structure of a rocker-arm. Finally, oxide sacrificial layers are etched away. This new micromachining technology is quite simpler than conventional method to fabricate joint structures, and the devices that are fabricated using this technology do not require a flexing structure for motion.

"역사는 거울"이라는 말은 반복되는 역사적 사실을 통해 우리는 적을 대비해야 한다는 뜻이다. 현재 우리는 북한의 핵과 미사일을 포함하는 각종 도발에 직면해 있다. 우리가 북한을 주적으로 설정하고 국민의 생명과 재산을 보전하기 위해서는 우리 군은 적의 위협에 항상 철저히 준비되어야 한다. 6.25 전쟁 전투사례를 보면 준비된 적과 무방비 상태의 국군 간에 벌어진 전쟁으로 요약할 수 있다. 북한군은 해방 이후 치밀한 계획 하에 중공군을 편입시키고 소련군 군사고문단 지원 하에 전투 장비를 배치하여 군단 급 훈련까지 마친 상태에 비해, 당시 국군은 대대급 훈련도 마무리 못한 상태였다. 전 평시 군사보안을 위해 나의 정보는 숨기고 적은 찾아서 대비해야 한다. 북한군은 전쟁을 준비하면서 치밀하게 국군의 편성과 배치, 그리고 운용사항에 대한 정보를 수집했으나 국군은 이에 대비하지 못해 초전에 고전을 면치 못했다. 이에 본고에서는 6.25 전쟁 초기, 개성일대 전투사례를 중심으로 군사보안의 교훈과 그 중요성을 제시하고자 한다.

Composite column design is strongly influenced by the computation of the critical buckling load, which is very sensitive to the effective flexural stiffness (EI) of the column. Because of this, the behaviour of a composite column under lateral loading and its response to deflection is largely determined by the EI of the member. Thus, prediction models used for composite member design should accurately mirror this behaviour. However, EI varies due to several design parameters, and the implementation of high-strength materials, which are not considered by the current composite design codes of practice. The reliability of the design methods from six codes of practice (i.e., AS 5100, AS/NZS 2327, Eurocode 4, AISC 2010, ACI 318, and AIJ) for composite columns is studied in this paper. Also, the reliability of these codes of practice against a serviceability limit state criterion are estimated based on the combined use of the test-based statistical procedure proposed by Johnson and Huang (1997) and Monte Carlo simulations. The composite columns database includes 100 tests of circular concrete-filled tubes, rectangular concrete-filled tubes, and concrete-encased steel composite columns. A summary of the reliability analysis procedure and the evaluated reliability indices are provided. The reasons for the reliability analysis results are discussed to provide useful insight and supporting information for a possible revision of available codes of practice.

Fibrous dysplasia is a relatively rare disease but the management would be quite challenging. Because this is not a malignant tumor, the preservation of the facial contour and the various functions seems to be important in treatment planning. Until now the facial bone reconstruction with autogenous bone would be the standard. Although the autogenous bone would be the ideal one for facial bone reconstruction, donor site morbidity would be the inevitable problem in many cases. Meanwhile, various types of allogenic and alloplastic materials have been also used. However, facial bone reconstruction with many alloplastic material have produced no less complications including infection, exposure, and delayed wound healing. Because the 3D printing technique evolved so fast that 3D printed titanium implant were possible recently. The aim of this trial is to try to restore the original maxillary anatomy as possible using the 3D printing model, based on the mirrored three dimensional CT images based on the computer simulation. Preoperative computed tomography (CT) data were processed for the patient and a rapid prototyping (RP) model was produced. At the same time, the uninjured side was mirrored and superimposed onto the traumatized side, to create a mirror-image of the RP model. And we molded Titanium mesh to reconstruct three-dimensional maxillary structure during the operation. This prefabricated Titanium-mesh implant was then inserted onto the defected maxilla and fixed. Three dimensional printing technique of titanium material based on the computer simulation turned out to be successful in this patient. Individualized approach for each patient could be an ideal way to restore the facial bone.

The skull defect can be made after the trauma, oncologic problems or neurosurgery. The skull reconstruction has been the challenging issue in craniofacial fields for a long time. So far the skull reconstruction with autogenous bone would be the standard. Although the autogenous bone would be the ideal one for skull reconstruction, donor site morbidity would be the inevitable problem in many cases. Meanwhile various types of allogenic and alloplastic materials have been also used. However, skull reconstruction with many alloplastic material have produced no less complications including infection, exposure, and delayed wound healing. Because the 3D printing technique evolved so fast that 3D printed titanium implant were possible recently. The aim of this trial is to try to restore the original skull anatomy as possible using the 3D printed titanium implant, based on the mirrored three dimensional CT images based on the computer simulation. Preoperative computed tomography (CT) data were processed for the patient and a rapid prototyping (RP) model was produced. At the same time, the uninjured side was mirrored and superimposed onto the traumatized side, to create a mirror-image of the RP model. And we fabricated Titanium implant to reconstruct three-dimensional orbital structure in advance, using the 3D printer. This prefabricated Titanium-implant was then inserted onto the defected skull and fixed. Three dimensional printing technique of titanium material based on the computer simulation turned out to be very successful in this patient. Individualized approach for each patient could be an ideal way to manage the traumatic patients in near future.

Mongolian government enacted the Foreign Trade Arbitration Law to modernize the practice of commercial arbitration. Nevertheless, the Foreign Trade Arbitration Trade Law fell short on a number of fronts and arbitration itself remained a distant second option to litigation within Mongolia. Law on Arbitration of 2003 aimed to modernize the Mongolian arbitration framework so that it would mirror the UNCITRAL Model Law on International Commercial Arbitration. At the same time, the Law on Arbitration 2003 made a conscious decision to deviate from international norms with respect to certain aspects in order to accommodate for the unique circumstances and characteristics of Mongolia. For example, unlike its UNCITRAL counterpart, the Law on Arbitration of 2003 did not include an exhaustive list of grounds for refusing the recognition and enforcement of arbitral awards. In that sense, the Law on Arbitration of 2003 was a resounding success and a drastic improvement on the Foreign Trade Arbitration Law. These factors convinced the Mongolian government to once again revise its arbitration law. This process, which started in 2008 with the help of foreign law firms and institutions, ultimately culminated in the Law of Arbitration of 2017. The chief objective of the Law of Arbitration of 2017 was to more closely adhere to preexisting international norms on arbitration such as the Model Law on International Commercial Arbitration, and there is no question that Mongolia has succeeded in doing so. This article thus concludes by explaining some of the noteworthy improvements made by the 2017 revisions, and by noting that Mongolia is now equipped with a truly international legal framework for arbitration.

본 연구에서는 좁은 지향각, 높은 최대 중심광도를 갖는 탐조등 광학계 설계 기술 연구를 진행하였다. 기존 탐조등 광원인 할로겐램프와 제논램프는 진동과 충격에 취약하며, 크기가 크고 무거워 운반에 많은 어려움이 있다. 또한 탐조등 후면부에 위치한 포물경은 제작 시 광원과 조립 오차에 따른 성능 저하와 낮은 광 효율의 단점을 지니고 있다. 이를 해결하기 위해 본 논문에서는 1 kW 할로겐램프를 150 W급 고출력 COB LED로 대체하고 목표 성능을 만족하기 위한 고효율 TIR 렌즈를 설계하였다. 이후 광학계 사출 시 발생하는 표면 오차를 해결하는 방안으로 TIR 렌즈 어레이를 제시하여 제작 신뢰성을 확보하였다. 설계된 광학계를 바탕으로 시제품을 제작한 후 시중 할로겐램프 탐조등과 성능을 비교하여 광학 성능의 우수함을 확인하였다.
