Abstract: The Earthquake is occurring more frequently in Korean Peninsula, where adjoins the circum-pan, Pacific Earthquake Belt being subjected to many Earthquakes. In 2009, Earthquakes in Korean Peninsula were occurred 60 times compared with 41 times on a yearly average of the last 10 years (1999~2008). And the Richter Magnitude (R.M.) records 6.9 of the maximum occurred in near DuMan River in Feb. 18, 2010. Inside their plant boundary, they have many kinds of processing equipment (P.E.) that are very high, huge and heavy. So, the stronger Earthquakes than 5.2 of R.M. in Mt. Sokri, 1978, will destroy these P.E. Then, these P.E. will be falling down, and hazardous materials will be leaked out and diffused. In the result, a great many people will be sacrificed; both neighboring county and city will be fallen into ruins. In general, according to the priority order, it is necessary to reinforce these P.E. on the Earthquake-design standards to be separately prepared by every plant. And upgrading of operation strategies is required to minimize total damages in the complex. Accordingly, this research shows what and how to protect and develop the processing equipment against Earthquakes.

Abstract: This paper reports on the performances and characteristics of the Sequencer and Data Acquisition (SDAQ) electronics board developed at the Section of Astronomy and Space Science of Department of Physics and Astronomy of the University of Florence, a digital system able to control signals generation and data acquisition, mainly designed for new generation of CCD cameras, but also suitable to drive and acquire data from a large variety of solid state detectors. The SDAQ electronics design is in fact able to generate several digital LVDS signals useful for driving and controlling a solid state detector and some ancillary signals needed to perform analog to digital conversion on data and to perform on-fly data processing, like Correlated Double Sampling (CDS) at the same time. The SDAQ is also able to provide digital signals in order to control data acquisition by means of FPGA internally generated FIFOs and externally mounted static RAMs. Even RAMs are directly controlled by means of FPGA-generated digital signals. Thanks to an external clock driver board and an analog to digital conversion and CDS board hosting the needed electronics components driven by SDAQ, it is possible to adapt, convert, and translate digital signal to TTL levels or other standard levels useful to drive detectors (e.g. CCDs analog phases or CMOS digital signals) and develop a stand-alone electronics system like a camera controller with some useful characteristics. Our electronics is in fact light, compact, and versatile as we were even able to drive a readout circuit developed to read very small currents (of the order of nA or hundreds of pA) generated by EUV-light driven photoelectric effect on Chemical Vapour Deposition (CVD) diamond film detector owning to its versatility. With smart logic residing internally the SDAQ FPGA is based on several finite states machines written in VHDL language (VHSIC Hardware Description Language, where VHSIC means Very-High-Speed Integrated Circuits) and able to efficiently inter-communicate thanks to internal signals and logical ports. The VHDL code hosts several test benches in order to perform by itself some HW and SW checking on the overall SDAQ board, requiring a minimized external circuitry. By this way it is quite simple and relatively fast to perform tests even when the SDAQ is operative (e.g. when it is working inside a CCD camera controller mounted on a ground-based telescope facility). SDAQ’s finite state machines are controlled by means of a FPGA-hosted decoder that is able to decode formatted command coming from the “outside world”. Hereafter we will describe the characteristics of the SDAQ controller as well as the tests and the engineering management procedures performed by means of ours electronics facilities.

Abstract: This paper aims to examine the Royal Thai Navy (RTN) defense materiel acquisition process and understand the implementation of Integrated Logistics Support (ILS) within the Ship building programs. The author introduces the research background clearly and gives enough details to the basic ideas and the theoretical analysis. ILS is credited as a United Stated Army tool and aims for maximum materiel availability with a minimum life cycle cost. This paper utilizes a qualitative methodological approach and uses two methods of data collection: documentary research and semi-structured interviews. The methodological approach employed the mapping of the documentation process to identify formal ILS practice in the Ship building program (including acquisition processes through published regulations and manuals that were formulated by the RTN authorities) and then was compared to the documents of other countries. The approach of accumulating a selection of 64 interviewed participants comprised of personnel from inside and outside RTN organizations. Results of this study reveal that the ILS in RTN acquisition process differs from that of ILS used in other countries. Consequently, the problems in using ILS include and led to limitations for the RTN in achieving the anticipated organizational aim and ILS objectives.

Abstract: Modern nations show great concern for safety management at workplace for obvious reasons. It’s critical to curb the appalling toll of occupational injuries that continues to plague humankind, and mitigate the occurrence of occupational injuries and work-related illnesses as they are daily facts in most industries particularly in manufacturing related enterprises. These impart a substantial life and causing economic losses in the most technologically advanced nations as well as in many emerging world. This study presents manufacturing accident investigation in a suitable way to plan and manage safety programme in a manufacturing settings. An accident investigation register was administered for a period of 12 months to capture the needed data and these were analysed employing accident investigation procedure. 328 injuries were investigated among the 293 workers for this study duration. The anatomical sites of injury were the hands and the wrists with 169 (52%) instances, while the feet and the ankles, legs and other sites accounted for 81 (25%), 62 (19%) and 16 (5%) of these injuries respectively. The most effective solution for eliminating complex multiple risks were carefully investigated and analyzed based on the existing program. The probable best solution to ultimately benefit both the worker and the employer was then established. It was found that the accidents investigated were predictable due to the synergistic effects associated with coupling repetitive production and hand intensive stress, age and work experience.

Abstract: Maintenance Management System is used to manage daily maintenance activities and planning guidelines for all the identified maintenance work activities. The purpose of this paper is to enhance the maintenance management system of private hospital in Kuwait state by using Computerized Maintenance Management System (CMMS) software to improve the overall equipment efficiency and maintenance indicators. It involves assessment of the impact of Maintenance Management Information System on the hospital building systems performance as well as the equipment maintenance performance. The assessment of impact of implementation of CMMS is identified through maintenance indicators such as Building Performance Index (BPI) and Maintenance Efficiency Index (MEI). These indicators have been developed specially for evaluation of the maintenance systems of health care facilities, where they are used here for the comparison of the periods before and after implementation of CMMS. The analysis reveals that there is a considerable increase in the Maintenance Efficiency Index and Building Performance Index and a simultaneous reduction in the maintenance expenses at the end of the period of the study.

Abstract: Problems of food security and preservation of reserved zones in the region of Central Asia in the conditions of the climate change induced by placement and construction of large reservoirs are considered. The criterion of an optimality of placement and construction of the reservoirs providing the minimum impact on environment is established. Need of the accounting of climatic parameters is shown at definition of the water quantity for the agricultural lands irrigation.
