I have here investigated how Sin Suk Jung, who had written many works with au sbject matter of Mountains, extended and reformed his mortal life through mountains. He chose "Mountains" as an object which wouldn't make any change forever and would be watching and testifying us. In his poems, at the first term, mountains seemed to be a meditation, but, at the latter term, seemed to be an indignation recording history. I believe it meaningful to know through mountains how he illuminated and intervened his image into reality.

It has been argued that the use of plastics can cause problems during design and manufacture owing to their low strength, relatively poor thermal conductivity and large thermal expansion. However, the advantages of plastics e.g., corrosion resistance, low cost, curtailment of weight, design flexibility etc., can compensate abundantly for the disadvantages. This study analyzes and compares the heat transfer performance characteristics of automotive compact oil cooler composed of plastic tube bundle with conventional metal oil cooler on the same core area basis as diameter, tube thickness, number of tube or tube arrangement varies. The performance analyses are accomplished by use of computational fluid dynamics program Fluent 6.2, which is verified and compared with the results of performance tests. The result of analyses is coincided with that of experiments. Flow pattern at air side according to tube arrangement is dominant factor which affects heat dissipation in case of similar total heat transfer surface area.

Korea was released from the Japanese colony by the help outside. So, we experienced the tragedy of fractricidal was called 6.25. This war which brocked out in our country is extraordinary as compared with orther wars in the history of the world, accordingly the war is different in many sides. For this reason, a rigid experience of 6.25 war became a literary proposition in our literary stage. The cardinal point of Korean literature in divided situations adopted two intensive propositions; the first proposition is to pursue the same nature of our people and the other is to overcome the problem of a divided situation in our country. But postwar generation present a marked contrast to the prewar generation in their sence. The former idiologically objectifies the situation of society, while the latter subjectifies the situation of cruel historic experience. Consequently, on the ground of the fusion of both sides, we must develope the quality of Korean literature considering divided situations. That must be neither a simple arrangement of the experience of war, nor an impatiently integrated argument. Korean literature considering the divided situation must be a literature illustration of the future which contains the Korean unification of spirit and nationalism.

기존의 Verilog테스트벤치로 원전용 안정등급 제어기기와 같이 복잡하고 높은 신뢰도를 요구하는 모듈의 테스트는 수작업으로만 수행된 결과를 가지고 RTL단계의 검증을 마무리하기에는 현실적으로 많은 시간과 노력이 필요하다. UVM은 기존의 테스트벤치의 한계점을 보완하는 계층적 테스트벤치의 구조를 갖고 있어 DUT의 검증을 위한 테스트개선에 대해 테스트벤치의 수정을 간편하게 할 수 있다. 비록 구축과정이 다소 복잡하긴 하지만 테스트 벤치의 컴포넌트들인 driver나 sequence 등을 사용함으로 constraint random test를 가능하게 하여 test vector 작성을 편리하게 한다. 본 논문에서는 기존의 테스트벤치와 계층적 테스트벤치인 UVM테스트벤치를 사용하여 실제 시뮬레이션 하고 커버리지를 분석하여 코드커버리지를 간편하게 향상 할 수 있음을 보였다. IIt takes a lot of time and needs the workloads to verify the RTL code used in complex system like a nuclear control system which is required high level reliability using simple testbench. UVM has a layered testbench architecture and it is easy to modify the testbench to improve the code coverage. A test vector can be easily constructed in the UVM, since a constrained random test vector can be used even though the construction of testbench using UVM. We showed that the UVM testbench is easier than the verilog testbench for the analysis and improvement of code coverage.
