  • In this paper, the beneficial effects of IHD deployments on the society were investigated, which is one of the enabling technologies related to the AMI investments. By focusing on the energy use reduction due to the feedback information from IHD, various favorable effects can be induced and quantified. The societal benefits should make a reasonable contribution to ensure that IHD should be prerequisite to the AMI deployments. In future, the quantification methodology would be applied to characterize and estimate the time-varying rate based demand response programs.

  • In-Home Display (IHD)는 가정에 에너지 사용량을 실시간으로 보여줌으로써 사용자의 자발적 에너지 절감을 유도할 수 있는 대표적인 방식의 하나이다. 최근 다양한 통신 방식을 이용한 IHD가 제안되고 있으나 통신의 도달 거리와 운용상의 한계로 가구 단위로 구성되는 것이 일반적이다. 본 연구에서는 국내의 대표적 주거환경인 기축 아파트 단지에 대한 IHD의 보급을 위하여 400MHz 대역의 RF 통신을 적용 한다. IHD의 활용도를 높이기 위하여 내장 배터리를 사용하는 경우 빈번한 교환을 방지하기 위하여 에너지 효율적인 운영이 필수적이다. 이를 위하여 제공 정보를 업데이트 주기에 따라 공통 전송 데이터, 장주기 갱신 데이터, 단주기 갱신 데이터 3가지 타입으로 분류하고, 각각의 프로토콜을 분리함으로써 에너지 효율적 통신 프로토콜 체계를 제안하였다. 이를 통해 서비스 품질의 저하 없이 데이터 발생량과 배터리 소모량을 각각 최대 23.4%와 31.5%로 감소시킬 수 있었다.

  • 본 연구에서는 우리나라 30세 이상 성인들의 허혈성심장질환(ischemic heart disease, IHD) 발생률을 계산하고, 지질지표(콜레스테롤, 중성지방, 고밀도지단백콜레스테롤, 저밀도지단백콜레스테롤)가 허혈성심장질환 발생에 미치는 위험도를 파악하고자 19개 대학 및 종합병원의 건강검진센터에서 검진을 받은 417,642명을 대상으로 1993년 9월부터 2009년 6월까지 평균 8.5년동안 허혈성심장질환의 발생을 추적관찰하였다. 자료수집은 검진자들에 대한 설문조사지를 이용하였고, 허혈성심장질환의 발생여부는 국민건강보험공단의 데이터베이스에서 확인하였다. 발생률은 발생밀도로 계산하였고, 혈청지질 지표에 따른 허혈성심장질환의 발생 위험도는 콕스의 비례위험 회귀모형을 이용하여 연령, BMI, 생활양식을 보정한 상태에서 성별에 따른 위험요인별 위험비와 95% 신뢰구간을 계산하였다. 연구결과 TC/HDL 비의 증가에 따라 IHD의 발생 위험비는 남자에서 1.21배에서 1.84배까지, 여자는 1.26배에서 1.86배까지 증가하였으며, TG/HDL 비의 증가에 따른 IHD의 발생 위험비는 남자에서 1.17배에서 1.49배까지, 여자는 1.42배에서 1.97배까지, LDL/HDL 비에 따라 IHD의 발생 위험비는 남자에서 1.26배에서 1.82배까지, 여자는 1.26배에서 1.68배까지 증가하였다. 결론적으로 혈청지질지표는 심혈관질환의 중요한 위험요인으로 총콜레스테롤, 저밀도지단백콜레스테롤, 중성지방은 혈중 농도가 높을수록, 고밀도지단백콜레스테롤은 낮을수록 IHD의 위험이 높아지는 것으로 나타났고, TC/HDL 비, TG/HDL 비, LDL/HDL 비에서 단독의 지질지표보다 위험도가 더 높게 나타나는 경향이 있었다. 따라서 추후 허혈성 심장질환의 예방 및 관리에는 혈청지질지표의 비도 감안하여야 한다.

  • An ischemic heart disease(IHD) is a anemic state of heart caused by disproportion between heart's demand and supply of oxygen. A patient who has this IHD feels serious chest pain called angina pectoris. In a keen condition it leads to a necrosis of heart muscles, known as myocardial infarction. In an ischemic heart disease the ECG waves gives us useful information of patients' heart. And CK(creatine kinase) in serum and Troponin T are the principal factors in diagnosis of IHD. In this study, the IHD patient classified by Sasang Constitutional Medicine had a notable medical effects. The symptoms of patient are disappeared and waves of ECG is closed to normal. The result of CK in serum is also recovered. So we report the healing process and results of this patient in this study.

  • Objectives: Ischemic heart disease (IHD) is a major cause of death in Korea and known to result from several occupational factors. This study attempted to estimate the current magnitude of IHD mortality due to occupational factors in Korea. Methods: After selecting occupational risk factors by literature investigation, we calculated attributable fractions (AFs) from relative risks and exposure data for each factor. Relative risks were estimated using meta-analysis based on published research. Exposure data were collected from the 2006 Survey of Korean Working Conditions. Finally, we estimated 2006 occupation-related IHD mortality. Results: For the factors considered, we estimated the following relative risks: noise 1.06, environmental tobacco smoke 1.19 (men) and 1.22 (women), shift work 1.12, and low job control 1.15 (men) and 1.08 (women). Combined AFs of those factors in the IHD were estimated at 9.29% (0.3-18.51%) in men and 5.78% (-7.05-19.15%) in women. Based on these fractions, Korea's 2006 death toll from occupational IHD between the age of 15 and 69 was calculated at 353 in men (total 3,804) and 72 in women (total 1,246). Conclusion: We estimated occupational IHD mortality of Korea with updated data and more relevant evidence. Despite the efforts to obtain reliable estimates, there were many assumptions and limitations that must be overcome. Future research based on more precise design and reliable evidence is required for more accurate estimates.

  • Objectives : Oriental medical doctors usually use the three-finger pulse diagnosis method to observe disease. Since it is difficult to diagnose ischemic heart disease (IHD) objectively by this diagnostic method, we performed the study to diagnose it as soon as possible by using Yuk Bu Jung Wee Jin Mac(六部定位診脈) and electrocardiogram(ECG). Methods : Patients who had abdominal discomfort were observed by Yuk Bu Jung Wee Jin Mac(六部定位診脈) and we presumed they had heart disease and checked them with electrocardiogram(ECG). Results : We diagnosed it early by using Yuk Bu Jung Wee Jin Mac(六部定位診脈) and electrocardiogram (ECG). Conclusions : The study suggests that it is easy to diagnose IHD early using Yuk Bu Jung Wee Jin Mac(六部定位診脈) and ECG. More data related to IHD is needed.

  • Purpose : Sayeok-tang (Sini decoction, SND) is a cold-dispelling formula used for cold deficiency syndrome and is composed of Aconiti Lateralis Radix Preperata, Zingiberis Rhizoma, and Glycyrrhizae Radix et Rhizoma. It is used for diseases such as myocardial infarction, heart failure, acute and chronic gastroenteritis, and gastric effusion. This study proposes the possibility of expansion of basic research and clinical applications for ischemic heart disease (IHD) through systematic analysis of domestic and foreign studies on SND. Methods : We collected studies within the last 10 years on the use of SND in IHD and excluded those lacking relevance. Selected studies were classified by research method and the main themes of the studies were analyzed for each classification. Result: Out of 15 studies, there were 5 animal studies, 8 metabolite analyses in animals, 1 in vitro study, and 1 systematic review. Our review suggests that SND may be used as an adjuvant to nitroglycerin and percutaneous transluminal coronary angioplasty, and may improve symptoms and quality of life of patients with IHD. Myocardial protective effects through antioxidant, anti-inflammatory, anti-apoptotic, and anti-hypertensive actions were confirmed through these studies. Effects on carbohydrate, protein, and lipid metabolism were also reported. Conclusions : This study suggests that SND has potential as a treatment for IHD.
