본 연구에서는 미국과 일본의 주식시장이 한국의 주식시장과 장기적인 관계를 가지고 움직이는지, 미ㆍ일 주식시장에서의 충격이 한국시장에 전달되는 효과가 있는지, 그리고 한국에서 추진되어 온 자본자유화조치가 한ㆍ미ㆍ일 주식시장간의 장ㆍ단기적 관계에 어떤 영향을 주었는지에 관하여 살펴 보았다. 본 연구의 실증분석결과는 다음의 세 가지로 요약된다. 첫째, 공적분검정을 통하여 공통화폐를 달러화로 통일한 경우에 10% 유의수준에서 한ㆍ미ㆍ일 3개국 주식시장 사이에 장기적인 관계가 있음을 확인하였다. 둘째, 오차수정모형(ECM)을 이용한 전이효과(spillover effects) 검정에서는 한국의 증시가 미ㆍ일 증시의 과거형태에 의해 유의적으로 설명되는 것을 관찰함으로써 미ㆍ일 증시의 단기적 충격이 한국에도 영향을 끼칠 수 있음을 확인하였다. 셋째, 이러한 전이효과는 1992년 자본시장 개방전후로 지속적인 호황을 구가하고 있는 미국보다는 일본의 경기 사이클과 보조를 맞춘 데서 비롯된 것으로 추측된다.

We compared three nations' diets on Year 2000 Korean, American and Mediterranean in the aspect of contribution of each to the development of cardiovascular diseases. We searched all the available evidences published. Korea has a very low incidence of cardiovascular diseses compared to the other countries even though they are increasing recently. In addition to many risk factors to these defenerative diseases such as diabetes millitus, hypertension, smoking, hyperlipidemia, sedentary lifestyle, etc., dietary factors are also contributing a lot to their development. High calorie, trans fatty acids, cholesterol, saturated fatty acids, alcohol, salt intakes are examples. Korean diet has superiority of low calorie, low fat, good fat proportion, high omega-3 fatty acids, vegetables, beans, and garlic and onions These are believed to contribute to low incidence of cardiovascular diseases in Korea. Korean diets was also found to have some issues for improvement such as high salt, low calcium, and higher use of barbequed meats. We concluded Korean people stay better off with Korean diet with some modifications.

Korea has a unique feature for telemedicine, including geographical mal-distribution of medical resources, immature health care delivery and heavy traffic in metropolitan areas. As one solution for these issues, we developed a tele-primary care system and tested its feasibility and user satisfaction. The tele-primary care system is based on PCs with videoconferencing hardware. The patient PC equipped with diagnostic peripherals such as blood pressure, stethoscope, magnifying camera, and so on. There are two remote clinics and 4 homes which are connected to the telecare center through leased lines or fast internet. Three hundred ninety eight patients were seen during the period of one year and each made about 2 visits on an average. The health problems seen through tele-primary care were not different from ones in primary care clinics. Drugs were prescribed over the half of the visits and labs were used only infrequently. Most users were satisfied and felt comfortable with this new type of medicine. We found tele-primary care system would be one solution for health delivery issues in Korea.
