  • The purpose of this research calculates the map manufacture cost and there are we even though we determine proper map price. We distinguished the budget item of NGI in 2003 with the direct cost to the overhead cost. A map manufacture cost classified a direct and overhead cost as a nap manufacture cost commonness cost and no relation cost and was calculated. The result to analyze the item of the charge, It is impossible to withdraw the map manufacture cost selling the map. This is because a map sale price inexpensive than the map manufacture price. We presented a two alternative in research to see consequently about a map price raising.

  • The utilization of waste and industrial byproduct materials, such as blast furnace slag, shales, poor coal and anthracite briquet ash, were investigated as a source of calcareous or argillaceous material in the manufacture of Portland cement. As a slag is similar to cement in chemical compoment and contains about 40∼50% of CaO, it's utilization in cement manufacture should be suitable. The burnability was increased and the heat of clinker formation was decreased by using slag. Some consideration should betaken in the use of large quantity because of sticking in suspension preheater kiln. Suitable quantities of colliery shales and poor coal should be useable in cement manufacture as a argillaceous materials and also its combustible materials should be utilized in cement manufacture. Anthracite briquet ash is also usable as a argillaceous source and it gives good burnability.

  • Korean firms have had a short history of foreign direct investment and export in China market entry. This present study empirically analyzed determinants of the choice of foreign market entry modes, Particularly forcusing on the China market entry on Korean manufacture firms. This study developed a research model to determinant factor in the China market entry and collected 77 survey responses from the Korean manufacture firms. This study model construct in the third factor, China market character, company character and product character. In China market character, the variance are China trade barrier, culture different, competition power. The variance in company character are internationalization experience, enterprise rage and entry motivation. Also the variance in product character are product different, customer service and cost advantage. It is researcher's main interest that which type of China market entry format brought most positive evaluation form the Korean manufacture firms. therefor, these research results turned out to be different a little both export and direct investment in China market of Korean manufacture firms.

  • In general, manufacture of medicine has demerit of long period in investment effect, high risk, expensiveness through new drug development. At empirical test, R&D investment for new drug development positively affects on profit in manufacture of medicine. In Korea, effect on R&D investment in manufacture of medicine occur faster than previous period. Manufacture of medicine is value added industry, compared to other industries. Moreover, U.S & Japan in R&D expenditure on sales respectively has 10.1%, 8.07%. This is 3-4 times, compared to R&D expenditure on sales of Korea. Conclusionally, the importance of R&D investment increase more and more in future. So, manufacture of medicine and Companies related this will care for R&D investment.

  • A system in package (SiP) generally contains a variety of systems such as analog, digital, optical and micro-electro-mechanical systems, integrated in a system-level package connected through a substrate. However, there are many electrical and mechanical reliability issues including the reliability issue for embedded structures. A mismatch of thermal coefficients of expansion among packaging materials and devices can lead to warping or delamination in the package. In this study, the effect of material properties of underfill, such as Young's modulus and CTE, are investigated through FEM simulation. Experimental investigation on the warpage of the package is also carried out to verify the simulation results. The results show that the reliability of the system in package is closely related to the material properties of underfill. The results of this study provide a good guidance for the material selection when designing the system in package.

  • Correct flow of various game manufacture among the justice which is used at the game development. and The understanding about the manufacture regards we making rather correct game. We justice understanding which we are correct in the image manufacture to become the reason air control of the game and We put the center in a 3B game image manufacture understanding. we are marked in maneuvered the game in actual game good. The image of the back of Cut Scene which is inserted at an opeuning incomparableness event time, we have been produced in this method. The thing which a 3D game image is utilized in a special effectiveness image though it is different from the game in the theater movie, we are the graphic which a game manufacture o'clock must be considered. The reason air control which the game player Is rather correct, we are regarded we offer the reason to immerse with his game.

  • The objective of the study is to investigate the distribution patterns of airborne bacteria and fungi in the feedstuff manufacture factory. The mean levels of airborne bacteria and fungi in the feedstuff manufacture factory were $113({\pm}18)cfu/m^3$ and $89({\pm}5)cfu/m^3$ for pelleting process and $198({\pm}5)cfu/m^3$ and $124({\pm}12)cfu/m^3$ for powdering process, respectively. The percentage of respirable and total concentration of airborne bacteria and fungi in the feedstuff manufacture factory ranged from 60% to 90% and were higher in pelleting process than powdering process. The ratio of indoor and outdoor airborne microorganism exceeded 1.0 regardless of types of feedstuff manufacture process. Based on the result of the study, there would be an association between environmental factors such as relative humidity and carbon dioxide and airborne microorganism's bioactivity.
