This study was performed to compare the effect of enrichement of rotifer and Artemia fed marine bacteria (Erymrnbatoer sp. Sπ-1) with those fed the different diets (Super Selco, ω-yeast and marine Chlorella) on the slime flounder larvae, Microstomus achne. Because the ratio of docosahexaenoic acid (DHA) to fatty acids in rotifer (dry weight %) fed on Super Selco and ESP-SR including Erythrobatcer sp. Sπ-1 was higher than that in rotifer fed marine Chlorella, the growth of the slime larvae fed the former showed better than the latter. And the ratio of DHA and highly unsaturated fatty acid (n-3 HUFA) to fatty acids in Artemia (dry weight %) enriched by ESP-A including Erythrobatcer sp. Sπ-1 were also higher than those in Artemia enriched by others or Artemia without enrichment. Larvae fed on Artemia enriched by ESP-A showed better growth and survival rate than those fed on Artemia enriched by others or Artemia without enrichment. With regard to dietary value of Erythrobatcer sp. Sπ-1, its use could improve the quality of the live foods for the slime flounder larvae.

Polyarteritis nodosa (PAN) has a broad spectrum of clinical presentation, since it affects small and medium-sized muscular arteries with microaneurysm formation, aneurysmal rupture with hemorrhage, thrombosis, and, consequently, organ ischemia or infarction. Although skeletal muscle involvement is well documented in patients with PAN, it can mimic more common diseases, and cause confusion and delays in diagnosis. PAN muscular involvement may have limited or early systemic forms with a benign course and excellent clinical response to corticosteroid therapy. Herein, we describe the clinical course and outcome of four unusual cases of PAN manifested by acute onset of pain and pitting edema in both lower extremities; in addition, we reviewed the relevant literature.

목적: 본 연구는 한국인 성인에서 인슐린저항성에 따른 대사증후군과 그 구성요소들의 유병률을 분석하기 위하여 수행하였다. 대상 및 방법: 한국건강관리협회에서 건강검진을 받은 30세 이상 성인 남녀 1,091명을 무작위로 추출하여 혈당, 혈청 인슐린, 총콜레스테롤, HDL-콜레스테롤, 중성지방, 체질량지수, 허리둘레, 혈압, 경동맥 내막중막두께 및 복부초음파를 시행하였고, 대상군을 인슐린저항성 정도에 따라 인슐린감수성군, 중간군, 인슐린저항성군으로 삼등분하여 그들의 임상 및 검사결과에 따라 대사증후군의 발병률을 분석하였다. 결과: 인슐린감수성군과 비교할 때, 인슐린저항성군에서 대사증후군의 상대위험도는 84.1배 증가하였고, 당뇨병 및 내당능장애는 10.2배, 고혈압은 1.8배, 이상지혈증은 2.8배, 고콜레스테롤혈증은 2.5배, 지방간은 3배 증가하였고, 전신성비만보다 복부비만이 인슐린저항성에 더 기여하는 것으로 나타났다. 결론: 본 연구는 단면적으로 수행되었으나, 인슐린저항성이 대사증후군의 중요한 위험인자이고, 심장혈관질 환을 비롯한 성인병의 예측인자로써 큰 의미가 있음을 시사한다. 따라서 성인병의 예방을 위해서 앞으로는 건강검진에 인슐린저항성을 평가하는 항목을 도입할 것을 권장한다. Background: This study was initiated to evaluate the prevalence of metabolic syndrome and its components as risk factors for cardiovascular disease according to insulin resistance in the Korean adult population. Methods: This study was conducted as a branch of the Korean Metabolic Syndrome (KMS) Study: 1,091 individuals aged 30 79 years participating in medical check-up in Korea Association of Health (KAH) were included in this study. We checked fasting blood sugar, fasting insulin, proinsulin, lipid profiles (total cholesterol, triglyceride, LDL-cholesterol, HDL-cholesterol), body mass index, waist circumference, blood pressure, carotid intima-media thickness (IMT) and abdominal ultrasonography. We divided all of the examinees into three groups (insulin sensitive, intermediate, resistant tertiles) according to their degree of insulin resistance and correlated this with the prevalence of metabolic syndrome. Results: The relative risk of metabolic syndrome was 84.1-fold higher in the insulin resistant tertile group compared to the insulin sensitive tertile group. Diabetes mellitus or impaired fasting glucose (IFG) was 10.2-fold; hypertension, 1.8-fold; dyslipidemia, 2.8-fold; hypercholesterolemia, 2.5-fold; fatty liver, 3.0-fold. Abdominal obesity rather than general obesity was more contributory to insulin resistance. Conclusion: Although this is a cross-sectional study, we can show that insulin resistance is one of the most-striking risk factors in metabolic syndrome and can be used as a predictor of cardiovascular diseases. Furthermore, we should monitor the healthy insulin-resistant population to prevent ongoing cardiovascular diseases. More prolonged data should be gained to refine the correlations of insulin resistance to metabolic syndrome.(Korean J Med 63:54-60, 2002)

Cardiovascular diseases are the leading cause of death and disability in Korea. Their risk factors can be classified as either modifiable or nonmodifiable and among modifiable factors are high bood pressure, elevated blood cholesterol, obesity and cigarette smoking. The purpose of this study was to evaluate the risk factors for the cardiovascular diseases in a rural community and to get basic data for the development of a community-based rick reduction intervention program. Evaluation involved population-based, cross-sectional samples of adult residents in a rurual community. We measured blood pressure, body fat percent by bioelectric impedance fatness analyzer and serum cholesterol and interviewed adult residents over 20-year-old age. Blood pressure was checked twice and hypertension was classified by the sixth report of the Joint National Committee on Detection. Evaluation, and Treatment of High Blood Pressure. The Cutpoints for high blood cholesterol was used National Cholesterol Treatment Guidelines and those for obesity was 25% in male. 30% in female. The results were as follows: 1. Prevalence of definitive hypertension was 59.7% in males and 54.4% in female. 2. Prevalence of hypercholesterolemia was 14.3% in male and 18.2% in female. 3. Prevalence of obese was 10.7% in male and 41.1% in female. 4. Among definitive hypertension, hypercholesterolemia, and obesity 52.1% possessed one risk factor, 12.6% two risk factors and 2.5% three risk factors in males. In females 41.4% possessed one risk factor and 27.6%. 5.7% respectively. 5. The smoking rate was 65.8% in males and 5.2% in females. Our results are used effectively for the community-based intervention towards cardiovascukr diseases risk reduction. However, because of limitations in our study design, further datas are needed including other risk factors and in-person clinical datas.

소셜 네트워크에서 위치 기반 서비스를 연동한 다양한 서비스들이 개발되고 있다. 이러한 서비스에서 사용자의 관심 대상이 되는 장소를 추천하기 위한 연구들이 진행되고 있다. 최근 소셜 네트워크 사용자가 동행인과 함께 이동 중 방문할 수 있는 장소를 추천받기 위한 요구들이 발생하고 있다. 본 논문에서는 소셜 네트워크에서 동행인 정보를 활용하여 선호 장소를 추천하는 기법을 제안한다. 제안하는 기법에서는 동행인과의 과거 이동 궤적을 비교하여 향후 방문할 장소를 제공한다. 또한, 소셜 네트워크에 연결된 사용자들이 선호하는 장소를 사용자와 동행인의 이동 궤적과 비교하여 소셜 네트워크 사용자의 선호장소를 추천한다. 성능 평가를 통해 응답속도, 정확도, 재현율 측면에서 제안하는 기법이 기존 기법보다 우수함을 입증한다. Various location based services have been developed in social networks. Especially, studies on the recommendation techniques of locations in that users are interested have been actively performed. Recently, demands on location recommendation that the users of social networks want to visit while they move along with companions have also been observed. In this paper, we thus propose a location recommendation scheme using the information of companions in social networks. The proposed scheme compares the past moving trajectories between companions and a user, and then provides the user with interesting locations. We also compare the interesting locations of friends connected in the social networks with companions" trajectories to recommend the popular locations. Our experimental results show that the proposed scheme outperforms the existing schemes in terms of response time, recall, and precision.
