The length of the links in an eccentrically braced frame will dictate the behavior of the frame. Link length controls the yielding mechanism and the ultimate failure mode. For short links, the links' shear forces reach the plastic shear capacity before the end moments reach the plastic moment capacity, and the links yields in the shear, forming a shear hinges. These links are termed "shear links." For long links, the end moments reach the plastic moment capacity before the links' shear forces reach the plastic shear capacity, forming moment hinges. These links are termed moment links." In long links, flexural yielding dominates the response, and very high bending strains are required at the link ends to produce large link deformations. In a shear links, the shear force is constant along the length of the links, and the inelastic shear strain are is uniformly distributed over the length of the links. This permits the development of large inelastic link deformations without the development of excessively high local strains. However, The use of eccentrically braced steel frames for the purpose of architectural cionsiderations such as openings and doors, areis dictating the use of longer links, though. Little data areis available on the behavior of long links under cyclic loading conditions. In This paper documents the results of an experimental program is that was conducted to assess the response of moment links in eccentrically braced frames. Sixteen specimens awere tested using a cyclic load. 편심브레이스골조의 설계에서 가장 중요한 인자는 링크보의 길이이다. 링크보의 길이에 따라 편심브레이스골조의 거동과 파괴메카니즘이 결정된다. 링크보의 길이가 짧아져 전단력에 의해 소성화되면 중심브레이스골조와 대등한 수평방향강성과 모멘트 연성골조의 연성을 동시에 확보할 수 있다. 또한 링크보의 길이가 길어지게 되면 링크보는 모멘트에 의해 소성화 되어 연성적인 거동을 확보할 수 없게 된다. 근래에 이르러 건축계획적인 측면에서는 링크보의 길이가 길어지는 것이 입면 및 단면계획이 용이하며, 그 필요성이 증대되고 있지만, 모멘트 링크에 대한 기존의 연구가 많이 수행되어 있지 않으며, 이와 관련된 자료가 부족한 실정이다. 본 연구에서는 실험을 통해 다양한 접합디테일을 가진 모멘트링크보의 거동을 규명하고 모멘트링크보의 거동을 개선시킬 수 있는 접합디테일을 제시하고자 한다. 4개의 접합 디테일을 가진 총 16개의 실험체를 계획하여 이력거동 실험을 수행하였다.

김태영,신형곤,김종택,김민호,이한교,Kim, Tae-Young,Shin, Hyung-Gon,Kim, Jong-Taek,Kim, Min-Ho,Lee, Han-Gyo 한국기계가공학회 2004 한국기계가공학회지 Vol.3 No.4

An experimental study on drilling of stainless steel is conducted using TiAlN coated drills and HSS twist drills with several cutting conditions; feed rate, spindle rotational speed, and dry/wet cutting. The effects of number of hole on the thrust force are examined by cutting force measurement. The flank wear of the drills and the change of hole diameter are quantitatively observed using a vision system. It is found that the thrust force in drilling with TiAlN coated drills decrease under dry and wet machining, whereas the flank wear resistance is improved.

본 연구는 재난안전정보의 효율적인 관리와 제공을 위해 LOD기반의 재난안전정보 서비스 모형을 제안하는데 그 목적이 있다. 이를 위해 온라인 조사 및 오프라인 인터뷰를 수행하여 재난안전정보 제공 현황을 분석하였으며, 재난안전정보를 6가지 영역으로 구분하였다. 재난안전정보 영역과 함께 도출된 재난안전정보 LOD 구축 시 고려해야 할 사항들을 기반으로 본 연구는 재난안전정보 LOD의 구축 과정을 상세하게 제시하였다. LOD 구축 과정은 한국정보화진흥원에서 발간한 링크드 데이터 구축 공정 가이드를 적용하였다. 특히, 재난안전정보 6가지 영역을 토대로 표준용어집 및 모델링 도구를 활용하여 온톨로지 개념 모델을 정의하였으며, 이를 기반으로 클래스와 속성을 제시하였다. 본 연구 결과를 통해 재난안전정보의 활용성이 극대화될 수 있을 것이라 기대할 수 있다. This study aims to propose disaster safety information service model based on LOD for effective management and dissemination of the information. To achieve the aim of this study, current state of disaster safety information was analyzed through online search and face-to-face interviews, and then the information was divided into 6 types. Finally, this study proposed specific process of building disaster safety information LOD service with considerations reflecting the information characteristics. The process for building LOD was based on Guidelines for Building Linked Data written by National Information Society Agency. Especially, ontology concept model was defined by using standard lexical resources and modeling tools based on 6 types of disaster safety information, and classes and properties were proposed. The results of this study will make disaster safety information more useful for common people.

Emergency free flap has been advocated to cover the severely injured extremity for more than two decades, due to its numerous advantages such as low incidence of flap failure and infection rate and early recovery of function. But there are very few reports about these. The authors report their experience in using the emergency free flap for reconstruction of extremities. For last 10 years, 4 patients ranging from 3 to 27 years old with severely traumatized extremities were treated with emergency free flap transfers. Three were males and the other was a female. Flap size ranged from $2{\times}5\;cm^2$ to $7{\times}22\;cm^2$. The locations of the recipient site were the dorsum of the foot, the cubital fossa, the popliteal fossa and the upper arm. The number of the donor sites used was as follows: one scapular flap, two parascapular flaps, and one radial forearm flap with the radial bone. All of the flaps survived without need of re-exploration. There was no infection or flap loss. Involved joints have recovered a normal range of motion. Therefore, we consider that the emergency free flap is a very safe and reliable method to cover the severely injured extremities.

Odontogenic keratocyst (OKC) with secondary inflammation involving the maxillary sinus was presented. Radiological diagnosis of this case was made based on the various findings from the cone-beam computed tomography, computed tomography and magnetic resonance images. There were calcified materials and impacted tooth within the lumen of the lesion, which is not uncommon in OKC. Histopathologic findings confirmed this lesion as OKC with secondary inflammation.

N-아실 아미노산계 음이온성계면활성제 중 sodium N-acyl-N-methyl-β-alaninate, sodium N-acyl sarcosinate 그리고 sodium N-acyl-N-methyl taurate 유도체 12종을 선택하여 묽은 수용액내에서 임계미셀농도와 미셀화 영역을 결정하는 새로운 방법으로서 컴퓨터프로그래밍에 의한 표면장력 곡선의 최대화를 제안하였다. 임계미셀농도와 미셀화 영역은 몇몇 실험치를 직접 프로그램에 대입함으로써 곡선의 최대화에 의해서 이론적으로 산정할 수 있다. 이론적으로 구한 임계미셀농도값들은 실측치와 거의 일치함을 알 수 있다. Micellization range and cmc for the dilute aqueous solution of N-acyl amino acid type anionic surfactants, that is, sodium N-acyl-N-methyl-β-alaninate, sodium N-acyl sarcosinate and sodium N-acyl-N-methyl taurate were investigated by computer programming. The extreme of the curvature of σ(C) as a new suggested method to determine the cmc and the micellization range was accomplished with computer programming. The values of cmc and micellization range can be obtained by the extreme of the curve by direct processing of only a few experimental data. The values of cmc particulary was in good agreement with those deduced intuitively from the shape of experimental curves of σ(C).

Arare case of primary malignant melanoma of central nervous system in 12-month-old infant with neuro-cutaneous melanosis is presented. Primary malignant melanomas in central nervous system are very rare in children, however, it is known that leptomeningeal melanosis is malignant in 40-50% with neurocutaneous melanosis. Spinal MRI, brain CT and MRI showed diffuse intradural extramedullary mass of entire spinal cord and enhancing mass in brain stem. CSF cytology revealed abnormal cells. Biopsy from leptomeninges of posterior fossa was compatible with malignant melanoma.
