        In 450mm wafers production environment for next generation Fab, one of the most significant features is the adoption of full automation to the whole manufacturing processes involved. The full automation system will prevent the workers from intervening the manufacturing processes as much as possible and increase the importance of each individual wafer noticeably, and thus require a more robust scheduling system for entire semiconductor manufacturing processes. The scheduling system for 450mm wafers production also should be capable of monitoring the status of each individual wafer and collecting useful Fab data in real time. In this study, we first analysis of cluster tool in 450mm wafers production environment, and then propose a real-time scheduling algorithm based on timetabling algorithm.

        Since 1980's, many enterprises have constructed Strategy Information System and tried BPR, ISP. Also, they implemented ERP and practiced the Process Innovation and Six Sigma for Management Innovation in todays. Although most companies had previous good plans, but those are not satisfied. Because of failed to change management and continued next activity. Many Project for Process innovation are ended as disposal project in my case, if they want next project, they need a new plan which needs additional fund and resource. This paper studied Process Innovation and Six Sigma in many things and proposed new model for continued project on the master plan. Also it proposed next study subject about ERP Optimization and Harmonization after implemented ERP which is considered as next step of PI.

        The Main Control Room(MCR) of Korean Next Generation Reactor(KNGR) has faced entirely new operation environment. The Computerized Procedure System(CPS) is completely different from existed Paper-based Procedure(PBP). The CPS which is improved by evaluation in this study is ready to be applied to the ergonomic foundations. In this study, we redesigned displays of the CPS as a Man-Machine Interface System(MMIS) to maximize human performance and to minimize human error and proposed an alternative display designs of the CPS applying principles related with MMIS.

        Recently social demand to achieve low fuel consumption and clean emission requires the development of new generation vehicle beyond the conventional vehicle concept. In this point, new generation vehicle is newly designed as electric vehicle, hybrid electric vehicle, fuel cell electric vehicle or 3 liter car etc. In order to develop new generation vehicle, it is very important to develop new materials and process technologies now. In this paper these new technologies are presented focusing on weight reduction specially. Steel body can be achieved 20-25% weight reduction by adoption of high strength steel and new process technologies, i.e tailored blank and hydroforming. Aluminium body can be achieved 40-50% weigt down by use of all aluminium monocoque body or aluminium space frame with aluminium panel. Plasitic composite body can be achieved 30% weight reduction comparing with conventional steel body.

        본 연구에서는 Electron Cyclotron Resonance plasma etching system 을 이용한 Ta 박막의 미세 식각 특성을 연구하였다. 염소 plasma를 사용하여 microwave power, RF Power, working pressure, gas chemistry 등의 변화에 따른 식각 profile의 영향을 조사하였고, pattern density가 증가함에 따라 발생하는 microloading 현상을 0.2μm 이하의 패턴에서 확인 하였다. 이를 개선하기 위하여 식각 과정을 두 단계로 분리하는 2단계 식각 공정을 수행하였으며 이를 통해 우수한 식각 profile을 얻을 수 있었다.

        The paper describes system design of next-generation Ship Simulator using Virtual Reality (VRSS), well known as human-computer interaction. VRSS system is required to have special condition that comprises multiple user participants such as captain, officer, pilot, and quartermaster. To cope with that condition, core technologies were explored and proposed multi-networking system with broker server. The evaluation of the proposed system was done with PC-based immersion-type VR device, constituted with HMD (Head Mounted Display), Head Tracking Sensor, Puck, Headphone, and Microphone. Using the VR device, assessment test was carried out in a virtual bridge with 3D objects, which are created by VRML (Virtual Reality Model Language) program. As results of tests, it is shown that the cybernetic 3D objects were act as if real things in a real ship's bridge. Therefore, interesting interaction with participants can be obtained in the system, Thus, we found that the proposed system architecture can be applicable to VRSS system construction.

        파밤나방(Spodoptera exigua(Hubner))에 미치는 chlorpyrifos-methyl(COM)의 화학적 불임효과를 미량국부처리법으로 조사하였다. 아치사량의 CPM이 5령충에 처리됐고 이로부터 형성된 성충의 산란수와 부화율이 분석되었다. CPM이 처리된 암수의 동계교배 집단에선 충체별 100 처리집단을 제외하고 처리농도의 차이에 따라 산란수의 차이를 보이지 않았다. 그러나 부화율은 CPM 처리농도에 따라 CPM 처리 집단이 무처리 동계교배 집단에 비해 뚜렸하게 낮았다. 무처리 암수와 CPM(100/충체)으로 처리된 암수를 상호교배한 두 집단들은 암수 모두 CPM으로 처리된 집단과 같은 낮은 산란수 및 부화율을 보였다. 이는 CPM이 우성치사인자의 화학불임제로서 작용했음을 나타냈다. 또 CPM이 이 해충의 유전방제법을 개발하는데 이용될 수 있음을 시사한다.

        Background : Atractylodes japonica koidz (AJ) is a perennial herb that belongs to Atractylodes genus. The dried rhizome of AJ is known as ‘Baek-chul’. The ‘Baek-chul’ is used as important traditional medicine in north-east Asia. It is considered to be effective for the treatment of stomach disorder, virus, diuresis, inflammation, arthritis. AJ is heavily depend on import from china and only few studies have been carried out. In this study, we develop SSR marker to build a foundation of breeding, to analyze genetic diversity and to construct core collection. Methods and Results : AJ resources was collected from each different place. To find simple sequence repeat (SSR) marker, we sequenced genomic DNA of AJ resources using Illumina HiSeq 2000 System. As a result of next generation sequencing (NGS), we obtained putative SSR loci. From these SSR primers, 553 SSR primer sets were designed successfully and confirmed polymorphism by in silico analysis. Nucleotide motifs ranged from tri- to penta-. Among these, 48 primer were tested in 4 individuals by capillary electrophoresis. Finally, selected 28 SSR marker were showed clear band and polymorphism by Electrophoresis. Conclusion : In this study, we developed 28 polymorphic SSR marker using NGS, and it could be used for analyzing genetic diversity of A. japonica. These marker would be useful for breeding of new cultivar in the future.
