Since mid-1990, Malaysia is continuously pursuing a policy of becoming one of the world economic superpowers by year 2020 under the strong leadership of the prime minister Mahatir. The top priority of Malaysia economic policy is put on the area of information technology(IT) with a variety of benefits and concessionary measures for foreign direct investments to Malaysia, which makes Malaysia one of the most attractive country for the Korean IT-related firms' foreign direct investment and/or mutual cooperation. In this paper, it has been tried to scrutinize the Korean IT-related firms' most suitable way of penetrating the Malaysia IT market including direct investments. The findings are as follows. Firstly, Malaysia can be developed as the strategic foothold for the whole southeast Asian market including China. Secondly, Malaysia IT market is attractive for the Korean firms' export of internet contents and educational softwares as subcontractors of two country's governments. Thirdly, a joint venture(JV) strategy between the Korean firms in the fields of business-to-business(b-to-b) or business-to-company(b-to-c) is highly recommendable. Fourth, a long-term planning seems to be essential in penetrating the immature market like that of Malaysia IT market. Finally, a penetration strategy in collaboration with government and the world-wide chinese society also seems to be recommendable.

This is a report of 4 case of external decompression about infraorbital paresthesia with transconjuctival incision in zygomatic complex fratures. The results are as follows. 1. Decompression for infraorbital nerve injury is indicated if paresthesia exists 5-7 days, although the patients have nondisplaced fractures of zygomatic complex. 2. Satisfactory results are expected within 1-2 weeks after surgical operation in early decompression of infraorbital nerve. 3. Paresthesia of the infraorbital nerve following fracture of the zygomatic complex may be persistent complication. 4. Scar tissues on the face are avoided transconjuctival approach.

A nonlinear feedback multivariable controller is used to stabilize a class of nonlinear systems. The controller is robust in the sense that the both output and internal state of the feedback system are ultimately bounded in the presence of matched uncertainties. The controller consists of decoupling control law, which linearizes the input-output behavior of the system, and vector saturating function for robustness correction. Restrictive assumptions on the structure of the system are required but they eliminate the ambiguities of the internal stability conditions which appear in the prior literature.
過 �슘血症에 있어서 atropine이 心肺動態에 미치는 影響

Cardiopulmonary effects of the vagal blocking with atropine in the hypercalcemic dogs were studied. The purpose of this study is to observe the vagal influence in the production of functional alterations of circulation and respiration by hypercalcemia. In this experiment, dogs were given atropine sulfate (0.032mg/kg.) intravenously immediately followed by intravenous infusion of 10% calcium gluconate. Pertinent data in these dogs were transient elevations of femoral artery mean pressure and right ventricular systolic pressure, and significant decreases in femoral venous pressure, pulmonary artery mean pressure and total pulmonary resistance. Also noted were significant increases in respiratory rate, minute ventilation, oxygen consumption, carbon dioxide elimination and arterial oxygen saturation. In comparison of these results to those in dogs in which calcium alone was given, decreases in femoral venous pressure, pulmonary artery mean pressure and total pulmonary resistance in the former were less marked than in the latter, whereas increases in respiratory rate, minute ventilation and carbon dioxide elimination were less pronounced. These results suggest that among various cardiopulmonary effects of hypercalcemia those on systemic hemodynamic are not significantly affected by the vagus but the increase in ventilation induced by hypercalcemia is closely related to the vagal tone.

In this study, consolidated drained triaxial compression tests on Joomunjin standard sand were performed to investigate the shear behavior of sand under different confining pressures and relative densities. The following characteristic drained shear behaviors of sand were observed from the test results: 1) Contractive behavior of loose sand; 2) Dilative behavior with softening stress-strain relationship of dense sand; 3) Contractive behavior of dense sand under high confining pressures; 4) Dilative behavior of loose sand under low confining pressures.
