This paper intends to analyze the effects of rise in overseas economic resources on the levels of domestic output, employment and the balance of payments. The theory about transmission of external shock including price changes in the open economies has been developed in various ways. The issue about transmission of external shock was approached in three diffrent directions; that is, monetary approach, keynesian approach and Scandinavian approach. Monetary approach stresses monetary features of balance of payments and does not accept the sterilization role of authority, and focuses on the overall balance of payments rather than trade balance. By contrast, the keynesian approach believes in authority’s full sterilization of the change in money supply in the foreign sector, and so it focuses on trade balance; and this based on the short run analysis rather than long run. And the third stresses more the foreign factors of inflation rather than the domestic elements by taking non-traded goods and traded goods separately. In this thesis. I dealt with some problems in the framework of “extended Scandinavian Model. ’’ which added the role of demand to “the basic Scandinavian Model”. Especially, I analyzed short run effects of the increase in the price of traded goods on inflation, balance of payments, employment and real national income, and prove the existence of the stability in the long run equilibrium. The price of traded goods is determined in the world market and given to the small open economy. Under the fixed exchange rate system, the domestic price of traded goods equals with the foreign price of traded goods multiplied by the exchange rate. The price of non-traded goods is determined in the domestic market and the market for nontraded goods is assumed to be always in the equilibrium. Thus the price of nontraded goods is adjusted flexibly to the domestic market disequilibrium. According to comparative analysis, an expansionary demand management policy raises income only at the expense of inflation and deterioration in trade balance. Devaluation improves the balance of payments and raises the price of exportable goods in terms of domestic monetary unit. But the effects of devaluation on income and the prices of non-traded goods are ambiguious. Export subsidy raises income but brings about inflation. But its effect on trade is ambiguious. Therefore the choice between expansionary and centractionary policy should be made after the analysis of the current-account situation and the inflation experiences of the country.

As a result of summit talk in June 15. 2000 between the two Koreas, We are also planning to have an access to TSR via a reconnection of the Korea railways. It became possible for the cargo between Europe and Far eastern Asia to pass through the railway, then to be connected with the TSR destined and/or Asia. There are several transcontinental railway lines connected with Korean peninsula - Europe. One of the most favorable plans among them is to restore the Donghae Line. The restoration of the railroad line between South and North Korea will play an important role in advancing reunification of Korea. Also their connection will extend to tremendous effects in military, economical, transportational and tourism areas. Korean corporation that might use the advantages offered by the TKR-TSR Linkage project could have considerably improved their competitive advantages in the international market. More than that, Korea may emerge as a transportation hub in Northeast Asia. Trade exchange between Russia and both Koreas will also increase. But we must overcome many problems such as the difference of gauge(Korean railroad : standard gauge, Russian railroad : wide gauge), vehicle, braking device, diagram, signal system, customs clearance, cargo tracing, ctc..

Purpose : Test bolus method presents no regular guide line even though it is generally used method. It is implemented the method of estimating maximum HU value in ascending aorta after setting nearly 10 seconds delay time. But this scan method is hard to operate accurate scan because of relatively long holding breath time of patient despite average time of getting maximum HU value is nearly 20 seconds. Therefore, in Cardiac CT scan, we want to find out proper delay time in test bolus method by comparison evaluation about correlation of maximum HU value of ascending aorta and time after previewing cardio-thoracic ratio in SPR(scan projection radiography) phase. Materials and methods : This study used Somatom Definition Flash 128 Channel DS Source(Siemens Health-care, Germany). The data was acquired from 130 patients(men:72 person, women:58 person, average age:58.83) who got Cardiac CT scan in university hospital(2014.1~2014.7). To estimate maximum HU value of ascending aorta, 10cc contrast media and 30cc saline was sequentially injected 5cc/sec. After 8 seconds from injection, time of getting maximum HU value of ascending aorta in time change was estimated. Heart size, heart rate, cardiac disorder is independent variable. Result was quantitatively and qualitatively analyzed. Results : After quantitative analysis, time of maximum HU value in ascending aorta was estimated 19.02±2.91 in cardio-thoracic ratio under 0.49, 19.81±4.77 in cardio-thoracic ratio under 0.5~0.59, 25.3±6.94 in cardio-thoracic ratio under 0.6~0.69, 28.98±7.1 in cardio-thoracic ratio under 0.7~0.79, 34.75±1.5 in cardio-thoracic ratio over 0.8. It shows significance difference in correlation analysis (r=.580 p<0.001). But in cardio-thoracic ratio, it shows negative correlation with maximum HU value in ascending aorta (r=-.458 p<0.001). Additionally, cardio-thoracic ratio has significance difference in patient cardiac disorder (p=.000). And time of getting maximum HU value in ascending aorta has significance difference (p=.000). However, Heart rate has no correlation with other variable. Time of getting maximum HU value in ascending aorta is most influenced from cardio-thoracic ratio, maximum HU value in ascending aorta, cardiac disorder (p<0.05),. In summary, the Most influenced cause of time of getting maximum HU value in ascending aorta is cardio-thoracic ratio (β=33.652, p=.000). It was increased 3.3652 seconds when cardio-thoracic ratio increased 0.1. In case of patient who has cardiac disorder (β=3.486, p=.021), it has 3.486 seconds longer than patient who has no cardiac disorder in time of getting maximum Hu value in ascending aorta. Conclusion : From previewing Cardio-thoracic ratio of patient from SPR image before getting Cardiac CT scan, considering Cardio-thoracic ratio under 0.6 has 19.89 seconds Test bolus delay time in average, Cardio-thoracic ratio over 0.6 has 0.1 increase makes 3 seconds increase in Test bolus delay time would reduce inconvenience in respiratory deficient of patient. And it also reduce movement of thoracic, it would be contributed to successful Cardiac CT scan using Test bolus method getting accurate maximum HU value in ascending aorta. 목적 : 일반적으로 사용되는 Test bolus 기법의 경우 지연시간에 대한 일정한 guide line이 제시되어 있지 않고 대략10초 전 후의 검사 지연시간을 설정한 후 상행 대동맥의최대 HU 값을 측정하는 방식으로 이루어지고 있다. 그러나 이러한 검사방법은 최대 HU 값에 도달하는 평균시간이 대략 20초 전후 임을 감안하면 피검자가 호흡을 참는 시간이 상대적으로 길어 정확한 검사가 이루어지기 어렵다. 따라서 심장 CT 검사에 있어SPR(scan projection radiography) 단계에서 심흉곽비를 미리 측정한 후 시간 변화에 따른 상행 대동맥의 최대 HU 값과의 상관관계를 비교 평가하여test bolus 기법의 적정한 검사지연 시간을 알아보고자 한다. 대상 및 방법 : 2014년 1월부터 2014년 7월까지 서울시내 일개 대학병원에서 Cardiac CT 검사를 시행한 성인 남녀 130명(남: 72명, 여:58명, 평균연령:58.83)을 대상으로 Somatom Definition Flash 128 Channel Dual Source(Siemens Health-care, Germany)CT 를 사용하여 연구를 진행하였다. Scan delay time을 결정하는 상행대동맥의 최대 HU 값을 측정하기 위해조영제10cc와생리식염수30cc를 초당 5 cc의속도로 순차적으로 주입한 후 8초 뒤Test bolus기법을 사용하여심장크기, 심박동수, 환자의 심질병을 독립변수로 시간변화에 따른 상행 대동맥의 최대 HU값 도달시간을 구한 후결과를정량, 정성적으로 비교 분석하였다. 결과 : 정량적 분석결과 상행 대동맥의 최대 HU 값에 도달하는 시간은 심흉곽비 0.49 이하에서 19.02±2.91, 0.5~0.59 이하에서19.81± 4.77, 0.6~0.69 이하에서 25.3±6.94, 0.7~0.79 이하에서 28.98±7.1, 0.8 이상에서 34.75±1.5로 측정되었으며 상관분석결과유의한 차이를 보였다(r=.580 p<0.001).그러나 심흉곽비의 경우 상행 대동맥의 최대 HU값과는 부적인 상관관계를 보였다(r=-.458 p<0.001). 이외에 환자의 심장 질병유무에 따라 심흉곽비가유의한 차이(p=.000)를 보였고, 상행 대동맥의 최대 HU 값에 도달하는 시간 또한 유의한 차이(p=.000)가 있는 것으로 나타났다.그러나 심박동수는 다른 변수들과 상관관계가 없는 것으로 나타났으며 전체적으로 상행 대동맥의 최대 HU값에 도달하는 시간에 미치는 영향은 심흉곽비, 상행 대동맥의 최대 HU 값, 질병의 영향이 통계적으로 유의한 것으로 나타났으며(p<0.05), 요약하면상행 대동맥의 최대 HU 값에 도달하는 시간에 가장 큰 영향을 미치는 요인으로는 심흉곽비(β=33.652, p=.000)로 심흉곽비가 0.1증가할 때 마다 3.3652초 증가하는 것으로 나타났다. 이외에 판막질환(β=3.486, p=.021)을 가지고 있는 환자의 경우 심질환이 없는 환자에 비해 상행 대동맥의 최대 HU 값에 도달하는 시간이 3.486초 증가하는 것으로 나타났다. 결론 : 심장 CT 검사 전 SPR 영상에서 심흉곽비를 미리 확인함으로써 test bolus의 지연시간을 0.6미만에서는 평균 19.89초, 0.6이상에서 0.1씩 증가할 때 마다 3초 이상 증가시켜 피검자의호흡부족으로 인한 불편을 해소함과 동시에 흉곽의 움직임을 최소화 하여 정확한 상행 대동맥의 최대 HU 값을 구하는데 있어 임상적으로 유용한 검사이라 사료된다.
