시설토마토에 발생하는 담배가루이 방제를 위한 허브식물의 유인효과

담배가루이 방제는 대부분 화학적 방제에 의존하므로 약제저항성 증가가 야기되므로, 트랩식물을 이용한 대체방제법 개발을 위해 허브식물들에 대한 담배가루이의 기주 선호성을 조사하였다. 완주군에 있는 국립원예특작과학원 내 토마토온실에서 실험을 진행하였으며, 허브 식물로 레몬밤, 초코민트, 로즈제라늄, 애플제라늄을 지면으로 부터 50 cm와 작물 상단부의 30 cm 위치에 각각 설치하여 담배가루이 밀도를 조사하였다. 허브식물의 설치 위치별 담배가루이 밀도를 각각 조사한 결과 레몬밤이 설치된 곳에서 높았으며 로즈제라늄과 애플제라늄은 오히려 기피하는 것으로 나타났다. 이 결과는 유인제, 기피제 및 트랩식물을 포함한 허브 식물을 사용하는 담배가루이의 대체방제법 개발에 도움이 될 것으로 기대된다. The problem of increased resistance to pesticides is caused by the management of Bemisia tabaci, which depends almost entirely on pesticides, and to solve this problem, we investigated the host preference of B. tabaci among herbal plants to develop a possible attractant for alternative control methods. Experiments were conducted in greenhouse tomatoes at the National Institute of Horticultural Science and Herbal Science in Wanju-gun. Major herbal plants such as lemon balm, chocolate mint, rose geranium, and apple geranium were installed 50cm from the ground and 30cm from the top of the tomatoes, then the density of B. tabaci was investigated. As a result of examining the density of B. tabaci by the location of the herbal plants, it was found that the lemon balm location showed the highest B. tabaci density while rose geranium and apple geranium were rather avoided. These results are expected to be helpful in the development of alternative B. tabaci control methods using herbal plants including attractants, repellents, and trap plants.
Metabolic and Cardiovascular Implications of a Metabolically Healthy Obesity Phenotype
서미혜,이은정 대한내분비학회 2014 Endocrinology and metabolism Vol.29 No.4
Metabolically healthy obesity (MHO) is a new concept in which an individual may exhibit an obese phenotype in the absence of any metabolic abnormalities. There are a number of definitions of MHO that utilize a variety of components. The findings of clinical and basic studies indicate that subjects with MHO do not exhibit an increased mortality, an increased risk of cardiovascular disease, or an increased risk of type 2 diabetes mellitus, as compared to normal-weight controls. Although these findings imply that metabolic health is a more important factor than obesity, several studies have shown that subjects with MHO have a similar risk of metabolic or cardiovascular diseases as those with metabolically unhealthy obesity. Thus, there is still debate regarding not only the implications of the MHO phenotype but its very existence. Accordingly, future studies should focus on developing a unified definition of MHO and distinguishing subjects who will be at a high risk for metabolic and cardiovascular diseases.

Background: The prevalence of obesity and related comorbidities is increasing worldwide, including in Korea. The Korean Society for the Study of Obesity released the Obesity Fact Sheet 2017 to address this problem in the Korean population. Methods: Data from the National Health Insurance Service Health Checkup database from 2006 to 2015 were standardized by age and sex using the 2010 Census. The definition of obesity was a body mass index (BMI) ≥25 kg/m2, and that of abdominal obesity was a waist circumference ≥90 cm in men and ≥85 cm in women. Multivariate adjusted Cox regression analysis was conducted, and hazard ratios (HRs) with 95% confidence intervals were calculated for comorbidities. Results: From 2009 to 2015, the prevalence of obesity increased from 29.7% to 32.4%, and that of abdominal obesity increased from 18.4% to 20.8%. Obesity with abdominal obesity also increased from 15.1% to 17.7%. Between 2014 and 2015, the prevalence of obesity increased until 30–40 years of age, but decreased from 40–50 years of age in men. In women, it increased until the mid-70s, and decreased thereafter. Abdominal obesity increased from 20–30 years of age to 70–80 years of age, but decreased thereafter. The HRs for type 2 diabetes mellitus, hypertension, dyslipidemia, myocardial infarction, and ischemic stroke were elevated in subjects with abdominal obesity, and their incidence increased as the BMI increased, but slowed down at BMI ≥35 kg/m2. Conclusion: Based on the Obesity Fact Sheet 2017, strategies for reducing the prevalence of obesity and abdominal obesity are essential.
