In this paper, the design method, design techniques and structure of a language for a SCARA type industrial robot, are presented. The proposed new language is modular and expandable using the C programming language and the 8086 assembly language. It is composed of monitor mode, editor mode, execution mode, I/O mode and teach mode. The developed language is implemented on the robot controller to verify its performance.

A new bacteriocin-producing lactic acid bacteria isolated from kimchi was identified as Lactococcus lactis JNU 534, presenting preservative properties for foods of animal origin. In this study, we present the complete genome sequence of the bacterial strain JNU 534. The final complete genome assembly consists of one circular chromosome (2,443,687 bp [base pair]) with an overall GC (guanine-cytosine) content of 35.2%, one circular plasmid sequence (46,387bp) with a GC content of 34.5%, and one circular contig sequence (7,666 bp) with a GC content of 36.2%.

In this study, we present the draft genome of Aureobasidium pullulans strain MHAU2101, which is the first strain to effectively control fire blight caused by Erwinia amylovora in Korea. The genome of strain MHAU2101 was composed of 28,669,322 base pairs, with a C+G content of 50.4%. The assembly comprised 17 contigs and had 99.22% completeness. The results of this study will be a valuable resource for future research on the biocontrol mechanism of A. pullulans strain MHAU2101.

In this paper, an analytical investigation on the track separation mechanism for tracked excavator was studied. Relative motions of track links, sprocket, idler and support rollers are very important in the driving of an excavator The interference and friction between each components lead to noise and vibration. And also this has a great influence on the life for tracked excavator. RecurDyn program was used for the three dimensional modeling of the track assembly. Investigating the interference between sprocket and track links, the mechanism of the track separation was analyzed.

Cassegrain interface module (CIM) of the fiber-fed high resolution echelle spectrograph has been designed and manufactured for the 1.8 m reflector at the Bohynsan Optical Astronomy Observatory. We also constructed a long slit spectrograph attached to this CIM, which would replace the earlier rather inefficient medium dispersion spectrometer. We present detailed description for design and manufacturing concepts of the CIM which consists of a slit assembly, slit monitoring system, calibration lamp system and a long slit spectrograph, in order to provide how the overall system and each part. are constructed. The preliminary performance test carried out so far seems to indicate a successful result.

무인기용 비행제어 소프트웨어는 인터럽트 핸들러에서 비결정적인 수행결과를 조래하는 경합이 발생될 수 있다. 이러한 유형의 경합을 탐지하기 위한 기존 방법은 원시 프로그램의 인터럽트 핸들러를 스레드로 변환하여 정적 경합탐지 도구를 사용하므로 프로그램 수행 시 실제 발생하지 않는 부정확한 경합(false positives)를 보고한다. 본 연구는 부정확한 경합 보고를 줄이기 위해서 원시 프로그램을 POSIX 실시간 스레브 프로그램으로 변환하고 Lockset기반 탐지기법 의해서 탐지된 공유변수를 대상으로 Happens-before 관계 분석기법을 이용하여 경합을 탐지하는 동적 경합탐지 도구를 사용한다. 제시된 방법의 실험을 위해서 Knob Assembly에 탑재되는 비행제어 소프트웨어를 대상으로 정적 경합탐지 도구와 동적 경합탐지 도구의 경합탐지 결과를 비교 분석한다.

Due to the potential importance and usefulness, usage of highly ordered nanoporous anodized aluminum oxide can be broadened in industry, when highly ordered anodized aluminum oxide can be placed on a substrate with controlled thickness. Here we report a facile route to highly ordered nanoporous alumina with the thickness of hundreds-of-nanometer on a silicon wafer substrate. Hexagonally or tetragonally ordered nanoporous alumina could be prepared by way of thermal imprinting, dry etching, and anodization. Adoption of reusable polymer soft molds enabled the control of the thickness of the highly ordered porous alumina. It also increased reproducibility of imprinting process and reduced the expense for mold production and pattern generation. As nanoporous alumina templates are mechanically and thermally stable, we expect that the simple and costeffective fabrication through our method would be highly applicable in electronics industry.

Japan is experiencing a most rapidly aging demographic. Despite this, the overall morbidity has been increasing due to the proportion of aging population that has increased rapidly along with the proportion of lifestyle related diseases, such as： all types of cancer, heart disease, stroke, diabetes, etc. As a result, the number of people requiring special care has become a serious problem. In response to these emerging health issues, the Strategic Planning force proposed the National Health Promotion Actualization Initiative in the 21st Century (“Healthy Japan 21”) so that it could be achieved by the year 2010. The policies should be conducted by providing adequately as well as with active participation and collaboration, effectively networking with the various organizations dealing with health issue. The Japanese Health Promotion Act passed by the National Assembly, 2001. As well as the many individuals that contributed to the development of this national health plan.

The largest array SKA (Square Kilometre Array) project was proposed by astronomers from 10 countries, and first coordinated by the LTWG (Large Telescope Working Group) formed at the General Assembly of URSI (International Union of Radio Science) in 1993. It enters the pre-construction phase (2012-2015), towards the 10% SKA construction (2016-2019) called SKA1 and the rest of SKA (2019-2023) called SKA 2, under the leadership of the SKA Organisation (SKAO) established on November 23, 2011. I will review the Chinese participation in the SKA project at national, regional and global levels in the past two decades. During such a Long March to the SKA, a number of national Megascience projects have taken root and have been (are being) successfully constructed, with costs at the 100 M US dollar level, including the largest dish FAST (Five-hundred meter Aperture Spherical Telescope), which can be seen as a forerunner of the KARST (Kilometre Area Radio Synthesis Telescope) project, being as one of the two LDSN (Large Diameter Small Number) concepts for realizing the SKA. A close look at the FAST project gives an impressive snapshot of the construction phase in China.

Tube hydroforming provides a number of advantages over conventional stamping process, including fewer secondary operation, weight reduction, assembly simplification, adaptability to forming of complex structural components and improved structural strength and stiffness. It can produce wide range of products such as subframe, engine cradle, and exhaust manifold. In this study, the effect of the heat treatment conditions such as post seam annealing (PSA) and bright annealing (BA) on the ovality and hydro-formability of steel tubes has been investigated. Hydroformabilities have been estimated by the bulging heights obtained at various processing parameters such as internal pressure, axial feeding and heat treatment conditions. The ovality and forming height are strongly influenced by material properties after heat treatments.
