  • Statement of problem: The position and length of cantilever influence on the stress distribution of implants, superstructure and bone. In edentulous mandible, implant-supported cantilever prostheses that based 4 or 6 implants between mental foramens has been attempted. Excessive bite force loaded at cantilever prosthesis causes bone resorption and breakage of superstructure prosthesis around posterior implants. To complement the cantilever length of conventional prosthesis, In 1992, (McCartney) introduced "cantilever-rest-implant" and Malo reported "All-on-Four" in 2003. Purpose: Analyze and compare the stress distribution of conventional cantilever prostheses with rest implant and All-on-$Four^{TM}$ implant prostheses. Material and method: The external loads(300 N vertically, 75 N horizontally) are applied to first molar area. The stress value, stress distribution and aspect of stress dispersion are analyzed by three-dimensional finite element analysis program, ANSYS ver. 10.0. Results: 1. The rest implant and "All-on-Four" implant system are superior to conventional cantilever prostheses to reduce stress on the bone and the superstructure around implants. 2. The rest implant was of the greatest advantage to stress distribution on bone, implant and superstructure. 3. With same number of implants, distally tilted implants are preferred to conventional cantilever prostheses for reducing the length of cantilever.

  • Cho and Shin (2016) recently demonstrated that an integrated HAR model has a forecast advantage over the HAR model of Corsi (2009). Recalling that realized volatilities of financial assets have asymmetries, we add a leverage term to the integrated HAR model, yielding the LIHAR model. Out-of-sample forecast comparisons show superiority of the LIHAR model over the HAR and IHAR models. The comparison was made for all the 20 realized volatilities in the Oxford-Man Realized Library focusing specially on the DJIA, the S&P 500, the Russell 2000, and the KOSPI. Analysis of the realized volatility data sets reveal apparent long-memory and asymmetry. The LIHAR model takes advantage of the long-memory and asymmetry and produces better forecasts than the HAR, IHAR, LHAR models.

  • Construction techniques for continuous steel bridges were applied to steel-concrete double composite box girder bridges. Concrete depth and length at the bottom of the steel box in the negative moment region were determined by plastic moment region and negative moment region of the double composite section, respectively. Construction methods, such as crane lifting method, free cantilever method, and incremental launching method were used for the analysis of the construction stage. Two cases of the construction phase were considered and analyzed for the stress resultant of double composite girders. The behavior of the nose-deck elastic system was examined by three-dimensionless parameters, such as the nose length, the unit weight of the launching nose, and the flexural stiffness of the nose. The adoption of the launching nose has become an effective solution in the incremental launching of steel-concrete double composite box girder bridges.

  • Although numerous theoretical and empirical studies on the capital structure have been performed, the studies on the capital structure of the high potential enterprises have not been worked. This paper performed empirical analyses for the first time to find out the determinants of capital structure of the high potential enterprises of Korea using the financial data of the manufacturing high potential enterprises listed on the Korea Exchange and KOSDAQ during 2010~2016. The results of regression analyses with debt ratio as dependent variable and profitability, firm size, asset tangibility and non-debt tax shield as independent variables show that the coefficients were relatively significant. The variables of the profitability and the tangibility were found to have positive relationship with the debt ratio. The non-debt tax shield were found to have in general positive relation with the leverage.

  • 반도체 소자의 선폭이 나노미터 스케일로 진입함에 따라 소자의 물리적 특성을 나노미터 스케일에서 정밀하게 측정하고자 하는 요구가 증대되고 있다. Atomic Force Microscopy (AFM)은 나노미터 이하의 해상도를 가지고 물질 표면의 기하하적, 전기적 특성 등을 측정할 수 있으므로 나노소자 연구에 필수적인 도구가 되었다. 그러나 AFM은 낮은 측정속도와 탐침의 기하학적 형상에 의한 AFM 영상의 왜곡 등과 같은 치명적인 단점도 가지고 있다. AFM의 낮은 측정 속도를 개선하기 위해서 진보된 마이크로머시닝기술을 이용하여 캔틸레버의 크기를 줄이거나 캔틸레버 위에 박막 구동기를 집적시키는 등의 노력이 진행되고 있으나, 이 경우 전통적인 식각 공정을 이용하여 캔틸레버 위에 tip을 형성하는 것이 매우 어렵다. 본 연구에서는 이미 제작된 캔틸레버 위에 전자빔 조사법을 이용하여 탄소상 tip을 직접 성장시킴으로써 전통적인 식각 공정에 비해 매우 간단하고 값싸며, 활용도가 높은 공정을 개발하였다. 탄소상 tip 성장에 필요한 탄소 소스는 dipping 방법을 이용하여 공급하였고, 시분할법을 사용하여 캔틸레버의 원하는 위치에 tip을 성장시킬 수 있었다. 이렇게 제작된 tip은 최대 $5{\mu}m$ 높이까지 가능했으며, 종횡비는 10:1 이상이어서 tip의 형상에 의한 AFM 영상 왜곡 현상을 최소화할 수 있을 것으로 기대된다.

  • 모터나 기계류와 같이 주변에서 발생하는 미활용 진동에너지를 전기에너지로 수확하기 위한 Piezoelectric Energy Harvester를 개발하고자 하였다. PZT-5H의 조성으로 후막세라믹 적층 구조 캔틸레버 타입의 압전시트를 통해 압전 에너지 하베스터를 제작하였다. 일반적으로 진동에너지를 수확하여 전기에너지로 변환시키는 압전 에너지 하베스팅 기술은 에너지 효율이 낮은 문제점을 가지고 있으므로 에너지 효율을 높이기 위한 방법으로 본 연구에서는 Unimorph 와 Bimorph 타입의 캔틸레버의 가로, 세로, 두께, 재료변수에 따라 발생하는 최적의 효율을 가지는 구조를 찾고자 하였다. 캔틸레버 각 변수에 따른 공진주파수 대역에서 발생하는 전압을 분석하여 50Hz의 공진주파수를 가지는 60*35*0.2mm의 캔틸레버를 설계하였다. 시뮬레이션을 통해 얻어진 결과를 실험적으로 검증하기 위해 전력량을 측정한 결과, Bimorph는 Unimorph 타입에 비해 2배가량의 향상된 발전특성을 가지며 에너지 하베스터에서 초당 $76.2\;{\mu}W$의 전력량을 가지는 것을 확인하였고 시뮬레이션 결과와의 타당성을 확인하였다.

  • As the network composed of numerous sensor nodes, sensor network conducts the function of sensing the surrounding information by sensor and of the sensed information. The concept of the battlefield is also changing to one that includes not only physical spaces but all areas including the networks of the nation's key industries and military facilities, energy facilities, transportation, and communication networks. In light of the changing warfare in terms of how it is conducted and what form it takes, the Korea military has to seek ways to effectively respond to threats of cyber warfare. In the past, although partial strategies on cyber warfare were studied, no research was done through the overall system flow. In this paper, key variables related to cyber warfare security are classified into personnel, management, and technology. A simple model and an extended model are suggested for each area, and based on the technology area of the extended model, formal methods are used to verify the validity and a detailed response strategy is suggested according to the identified leverage.

  • The use of tapered structural members was first proposed by Ami rikian for the economical use of materials.Generaly, tapered members are used in single-story structures with one or more bays and in cantilevered sections of ate architectural representation. If only focused on the section performance, however, the width-to-thickness ratio or t apered ratio can exced regulations. Such a case requires a study on the behavior of tapered members. To investigate the plastic and local buckling behavior of web-tapered beams, seven steel beams were the tapered ratio and the width-to-thicknes ratio. The results of maximum strength, strength deterioration, and stiffnes deterioration were compared.
