The corrosion fatigue test were carried out to evaluate the fatigue characteristics of accelerated cooled (ACC) TMCP high tensile strength steels and weld joint with high heat input by one side one run submerged are welding. In this paper, the fatigue crack growth behaviors were investigated with the center crack tension specimen of base metal and heat affected zone in substitute sea water and air, respectively Main results obtained are sunnarized as follows: 1. The fatigue crack growth rates in sea water faster than those in air environment for the different heat input values, crack growth rate of base metal is very fast and effect of heat input is not remarkable. 2. In HAZ (82kJ/cm, 116kJ/cm), the crack branching phenomena were observed in both air and sea water environment, 3. In SEM observation, the corrosion effect on base metal was larger than that on HAZ in corrosion environment.

디지털 영상콘텐츠 분야에서의 원소스 멀티유스(One-Source Multi-Use) 전략은 하나의 소재(onesource)로 다양한 상품(multi-use)을 개발, 배급할 경우 시장에서의 시너지효과가 크다는 판단에 의해 서로 다른 장르에 적용하여 파급효과를 노리는 마케팅관점에서 중시된 이론으로 알려져 있다. 최근 문화산업재의 온라인화 및 디지털 콘텐츠화가 급진전되고 각 장르간 경계가 모호해지고 매체간 이동이 용이해짐에 따라 이 전략은 창구효과(Window Effect)가 큰 문화산업의 특성에 맞추어 기획 단계부터 영화 게임 애니메이션 캐릭터 등을 총 망라하는 문화 콘텐츠를 개발뿐만 아니라 플랫폼 재활용측면에서 소프트웨어엔지니어링 분야까지 확장되고 있는 추세이다. 특히 하나의 인기 소재만 있으면 추가적 비용부담을 최소화하면서 다른 상품으로 전환해 높은 부가가치를 얻을 수 있다는 점에서 각광받고 있으며, 관련 상품과 매체를 체계적으로 관리할 수 있어 마케팅 및 홍보 플랫폼 제작 등에서 제작비용 절감효과를 누릴 수 있다는 장점이 있다. 이러한 관점에서 본 연구는 세계적으로 영상콘텐츠산업 비중이 높은 한 미 일 3국의 제작방식의 비교를 통하여 각국이 선호하는 장르 및 제작방식을 고찰하고자 한다.

본 논문에서는 하나의 층에 두 가지의 주파수 대역을 내장해서 인레이를 구성하는 One-Sheet Inlay 패턴을 이용한 RFID 태그 안테나를 개발하였다. One-Sheet Inlay RFID 태그 안테나는 이종의 RFID 안테나를 하나의 카드에 내장해서 사용하는 방법이 아니라 하나의 시트에 13.56MHz와 900MHz RFID 태그 안테나를 구현하였다. 제안한 방법을 유용성을 입증하기 위하여 실험 장치를 구성하였고, 6개의 패턴을 설계하여 각각의 패턴에 대해서 인식거리를 평가하였다. 설계한 One-Sheet Inlay RFID 태그 안테나 중에서 패턴 5가 13.56MHz RFID 태그에 대해서는 인식거리 3.5cm이고, 900MHz RFID 태그에 대해서는 인식거리 5.34m로 우수한 성능을 나타내었다.

This paper provides simulation-based results of effect analysis of sample size and sampling periods on accuracy of reliability estimation methods using multiple comparisons with analysis of variance. Sum of squared errors in estimated reliability measures were evaluated through applying seven estimation methods for one-shot systems to simulated quantal-response data. Analysis of variance was implemented to investigate change in these errors according to variations of sample size and sampling periods for each estimation method, and then the effect analysis on accuracy in reliability estimation was performed using multiple comparisons based on sample size and sampling periods. An efficient way to allocate both sample size and sampling periods for reliability estimation tests of one-shot systems is proposed in this paper from the effect analysis results.

The most fundamental topic of the Daesoonjinrihoe faith is how the human Kang Jeongsan can be supreme god(GucheonSangje). This statement is based on the Great Work of Sangje that is called Chunji-Gongsa. The documents on Chunji-Gongsa is founded in Jeongyung, the scripture of Daesoonjinrihoe. But it's not easy for us to understand it because of its holistic and symbolic expression. There are duplicate phrase of Chunji-Gonsa in one scripture or included it in another chapter that is not Chunji-Gongsa as well. So we need to analyze it more systematically and understand it reasonably. Especially in order to write this article I would like to use the view of Guchun-Sangje theory. This article is composed with three chapters except preface and conclusion. The first one is the relation between Chunji-Gongsa and Guchun-Sangje. The second one is to analyze Chunji-Gonsa. The third one is the doctrinal significances of Chunji-Gongsa.

Kefir, originating from Caucasus, is an acidic, alcoholic fermented milk product with little acidic taste and a creamy consistency. It is recognized in having beneficial effects infor the prevention and treatment of cancer. For example, Kefir has possesses a chemopreventative effect on carcinogenesis. There has recently been a strong focus on fermented milk foods containing a mixture of several functional organic substances and various probiotic microorganisms. Hence, the purpose of this review paper was to evaluate the scientific evidence for the effects of kefir on cancer prevention and treatment. Some of we analyzed and summarized data-relating to the effects of kefir on cancer. The cacers that kefir has an effect on are as follows: colon cancer, breast cancer, leukemia, sarcoma, skin cancer, gastric cancer. This review suggests that (1) kefir could be associated with cancer prevention, (2) kefir has beneficial effects in cancer treatment, and (3) kefir has various bioactive components including peptides, polysaccharides and sphingolipids, which contribute tofor itsthese anti-cancer properties. Furthermore, furthermore, studies were performed in order to obtain as to get the scientific evidence of kefir's anticancer activity: (1) improved protective effectiveness in vivo (human subjects or animal model), (2) isolation and identification of various bioactive components, and (3) mechanisms associated with beneficial effects.

One-dimensional array of InAs quantum dots (QDs) have been grown on V-grooved GaAs substrates by low-pressure metalorganic chemical vapor deposition. Atomic force microscope images show that InAs QDs are aligned in one-dimensional rows along the ［011］oriented bottom of V-grooves and no QDs are formed on the sidewalls and the surface of mesa top. Capability to grow one-dimensional InAs QDs array would feasible for the single electron tunneling devices and other novel quantum-confined devices.

The SVDD(support vector data description) is one of the most well-known one-class support vector learning methods, in which one tries the strategy of utilizing balls defined on the kernel feature space in order to distinguish a set of normal data from all other possible abnormal objects. The major concern of this paper is to consider the problem of modifying the SVDD into the direction of utilizing ellipsoids instead of balls in order to enable better classification performance. After a brief review about the original SVDD method, this paper establishes a new method utilizing ellipsoids in feature space, and presents a solution in the form of SDP(semi-definite programming) which is an optimization problem based on linear matrix inequalities.

The objective of this paper is to introduce very fast but still stable solution using finite element procedures, and it has been used in an iterative mode for product design applications. A lot of numerical techniques have been developed to deal with the material, geometric and boundary condition non-linearities occurred in the stamping process. One of them, the One-Step FEM is very efficient and useful tool for a design and trouble-shooting in various stamping processes. In this method, the mathod, the material is assumed to deform directly from the initial flat blank to the final configuration without any intermediate steps. The formulation is based on the deformation theory of plasticity and the upper bound theorem. As a result of the calculations, the initial blank shape is obtained, together with the material flow, strains and thickness distribution in the part.

Fuzzy controller is one of the succeed controller used in the process control in case of model uncertainties. But it my be difficult to fuzzy controller to articulate the accumulated knowledge to encompass all circumstance. Hence, it is essential to provide a tuning capability. There are many parameters in fuzzy controller can be adapted, scale factor tuning of normalized fuzzy controller is one of the adaptation parameter. Two adaptation methods are implemented in this work on an experimental thermal process, which simulate heating process in liquefied petroleum gases (LPG) recovery process in one of petrochemical industries: Gradient decent (GD) adaptation method; supervisory fuzzy controller. A comparison between the two methods is discussed.
