  • Recently, the FPD industry has faced the limit in market growth due to lack of new growth engine as a replacement of television. With sluggish market demand deepened by global economic crisis and persistent concern over panel oversupply, growth of the panel market has sharply slowed down, and profitability has been eroded. This also has tremendous effect on related industries including component, material and machine industries, spreading a sense of crisis across the whole FPD industry. Under this circumstance, for the FPD industry to take off once again, all involved in the FPD industry must cooperate and come up with innovative ideas, and identify the driving force to realize turbo-charged growth.

  • The principal object of this paper is to study a class of matrix polynomials associated with Humbert polynomials. These polynomials generalize the well known class of Gegenbauer, Legendre, Pincherl, Horadam, Horadam-Pethe and Kinney polynomials. We shall give some basic relations involving the Humbert matrix polynomials and then take up several generating functions, hypergeometric representations and expansions in series of matrix polynomials.

  • A novel thin film processing technique has been developed for the fabrication of ultrathin films of conducting polymers with molecular-level control over thickness and multilayer architecture. This new self-assembly process opens up vast possibilities in applications which require large area, ultrathin films of conducting polymers and more importantly in applications that can take advantage of the unique interactions achievable in the complex, supermolecular architectures of multilayer films.

  • Manufacturing industry is on the verge of a major paradigm shift. This shift will take us away from mass production, way beyond lean manufacturing into a world of new intelligent and agile manufacturing. We spent most of our time during the 1980s copying the Japanese. This paper studys reengineering methodologies to build up low-cost manufacturing systems efficiently in Korean companies

  • The objective of this study is to investigate the perception of males about make-up and the make-up process, analyze principal factors affecting their decision when purchasing cosmetics and, ultimately, to provide basic data for further survey and research into features of cosmetics and their satisfaction. The subjects of the study a.e male adults living in Jeonju, Iksan and Gunsan cities of Jeonbuk province. Surveyors made direct interviews with the subjects from October 21 to 30, 2003 and collected 174 questionnaires from them, which were subsequently put to the final analysis. The demographic characters of the surveyed showed that 60.9% of them were in the age ranging 30 to 39, 75.3% married, 69.5% undergraduates or graduates, 39.1% self-employed, 25.9% earning more than 3.01 million Won monthly and 43.7% spending less than 10,000 Won a month for cosmetics. Their make-up and purchasing pattern of cosmetics featured that 54.0% of the surveyed use cosmetics for skin care, 54.0% for cleanness and health, 84.5% for foundation(lotion or skin lotion) only, and 60.9% once a day. Out of the surveyed males, 79.3% haven't experienced any adverse side effects after make-up. Of those who experienced, 80.5% named disagreement of cosmetics with skin for the reason. As for kind or symptom of the side effects, 38.8% set forth itching. Among those who had aftermath or intoxication from make-up, 52.8% said they could recover naturally. According to the survey, 57.5% felt somewhat awkward after make-up, but not quite bad though. Thirty-seven point nine percent of the males surveyed replied they cared little about the purpose of male-oriented cosmetics. Quality was raised by 31.0% as the foremost issue to improve. Television turned out to be the main source for 56.9% of the surveyed to get information about cosmetics. For 56.35%, general discount shops are preferred to buy cosmetics and 24.7% of them take ones recommended by salespeople. When buying cosmetics, 47.1% considered color and fragrance most seriously.

  • The issue of adjuncts has long been a neglected field of linguistic study whether it be syntactic or semantic. It is only in Pustejovsky (1995) that we find a brief mention of adjuncts. In addition to what the author calls true arguments, default arguments, and shadow arguments, he sets up a class of true adjuncts citing the following sentence, Mary drove down to new York on Tuesday. We will take up a small lexical item sugiru in Japanese, and we will argue that we should posit the notion of implicit adjuncts in describing the properties with the small Japanese lexical item sugiru. Throughout the discussions that follow we will demonstrate how the notion is independently motivated irrespective of what linguistic theory we are going to adopt.

  • The East Sea Branch (ESB) of KORDI will be launched in 2008. She will take a role of monitoring the sea surface topography and temperature by satellites, short- and long-term sea levels by tide gauges, coastal currents and open-sea circulation by setting up coastal radars and mooring current-meters and acoustic equipments, as well as monitoring nearshore processes, coastal erosion and water pollution. A basic program of coastal zone management will help ocean-policy makers to set up right decisions based upon scientific background of the regional data in the East Sea. Networking among the neighboring countries around the sea will supply more useful information not only for experts but also for ordinary vacationers or fishermen. In order for this program to be successfully settled down during the next decade, it is necessary for a leader to have the right vision to attract more experts from global brain pools and to manage the ESB as a leading-edge observatory in the world. Details about this leading-edge operational program are introduced in the text.

An Empirical Study on Factors that determine on Success Factors of Total Quality Management Implementation (지속적인 종합적 품질경영(TQM) 실행의 결정요인에 관한 연구)

  • According to the study of TQM implementations, the odds that an organization will successfully implement total quality management are two to one-against it. Based on the Brown's study, two thirds of all TQM implementations are dropped or fail altogether. However, organizations armed with knowledge of the factors that have the biggest impact on their success can take steps to influence or change those factors. In this paper, we studied on the degree of influence between those factors and successful start up and alignment factors. Based on extensive literature reviews those factors, threat, commitment, plan, progress and strategy are determined. Also we determine the successful start up and alignment factors. A framework of research including above factors is developed and tested statistically The Perceived data are collected from managers of quality departments of 141 Korean firms through survey. The results show that the rating of those factors which determine success of implementing TQM is progress, commitment, strategy and progress. But the factor of threat shows negative influence for the success of implementing TQM.

  • The effects of phosphate concentration in the medium, feeding of biosynthetic precursor, and the addition of exogenous berberine on cell growth and berberine production were studied in cell suspension cultures of Thalictrum rugosum. The depletion of phosphate in the medium enhanced the specific productivity up to twofold with significant release of berberine into the medium. Extracellular berberine was 19% of the total in the culture without phosphate while it was 2-5% of total berberine in the culture with even low amounts of phosphate. Precursor feeding was not effective in enhancing alkaloid formation. Initial presence of exogenous berberine did not have much effect on cell growth and alkaloid production. It was found that the cells have the capacity to take up large quantities of berberine. When $500{\;}mg{\cdot}l^{-1}$ of berberine was added exogenously at the beginning, 81% of total berberine was found in the cells.
