The Middle East where Asia, Africa, and Europe meet together is very important from the viewpoint of world strategy. For generations it has been a fighting arena between the continental power, Russia, and the oceanic power, the West. Today it is still known as a danger zone where larg and small conflicts break out chronically. Especially, the Iran-Iraq War from 1980 till 1988 can be regarded as the most tiresome and wasteful war since the World War Ⅱ. The common features of wars among countries in the Third World are that they are short and intensive and that super powers frequently intervene in them. But the Iran-Iraq War was largely uncommon in three respects. First, the war started in the form of a border dispute. Second, it became protracted and altered into a war of attrition. Thirdly, and most importantly, there were no direct interventions of super powers. The Gulf in the 1980's was the only region where super powers didn't intervene either politically or militarily, though that region was closely connected with their vital interests. This suggests that the war resulted from the peculiar troubles in the Gulf. It is well known that religion has more important effect upon politics in Islamic culture than in any other. In this context, we can suppose one of the main causes of the Iran-Iraq War was religious. To understand the power relations in the Middle East, indispensable is the inquiry into this characteristic of Islamic world. Therefore, the purpose of this study is not only to analyze the causes of the Iran-Iraq War, but to provide general understandings of the special relationship between politics and religion in Islamic world.

Machines have been used simply for arithmetic operations and documentation. However, with the development of technology, a new generation of artificial intelligence has begun. Machines are not just tools that can be calculated, but they have been commercialized in various fields, such as natural language processing technology that can understand and communicate human language, or video fields, where human dependence was high. Since 2016, the AI game, “Alphago,” has defeated Lee Se-dol with a significant difference in skill, interest in AI has increased sharply. Machines have started to replace human jobs because of their excellent performance, low cost and competitive edge. In this paper, I would like to present a plan on how to use artificial intelligence to affect human jobs and how to improve productivity effectively by cooperating with machines and humans in the future.

표면영상유속계(SIV)는 기존의 입자영상유속계(PIV)의 원리를 이용하여 하천의 표면유속을 측정하는 방법이다. 본 연구에서는 경제적이고 효율적인 유속측정 기법인 SIV 기법을 이용하여 국내 3개 하천에 대하여 현장 유량측정에 적용하였다. 현장 영상분석은 다중카메라 방식을 이용하였고 영상분석과정에 필요한 참조점과 횡단면 자료는 측량을 통하여 획득하였다. SIV로 측정된 유속을 검증하는 수로 실험의 결과, 평균오차 10% 이내의 정확도를 보여 정확한 유속측정이 가능함을 확인하였다. 그러나, 실제 하천에의 적용에서는 저수위시와 악천후시에 대해서는 20 % 이내의 오차를 보이는 것으로 나타났다. 향후 SIV 기법의 문제점들을 해결한다면 언제 어디서나 효율적이고 경제적인 유량측정을 할 수 있을 것이다. 그리고 이를 활용하여 실시간 하천정보시스템으로 발전시킴으로써 하천 관리에 큰 도움이 될 것이라 판단된다. Surface Image Velocity (SIV) is a technique which measures the surface velocity of river by using the principle of Paticle Image Velocimetry (PIV). The technique is economical and efficient way to measure velocity in rivers. The present paper aims to apply the technique to three rivers in Korea. It uses pairs of river surface images taken with two digital-cameras and reference points and cross section data which were acquired through plane survey. The performance of SIV was verified with automatic cart on an experimental flume. The test revealed that average error was less than 10 %, which assures that SIV can be used to measure velocity accurately. When it was applied to rivers with low water levels or rough weather condition, however, it showed the error about 20 %. If the problems of SIV technique are settled down, it can be one of the most convenient and economical ways to measure water discharge anytime and anywhere. And then it would be helpful to river management as developing a real-time river information system.
