시설 고추에 발생하는 꽃노랑총채벌레 방제를 위한 목단피 추출물의 살충효과
서미혜,서경혜,최경산,이선영,윤정범,박정준 한국응용곤충학회 2023 한국응용곤충학회지 Vol.62 No.4
총채벌레는 우리나라에 60여 종이 알려져 있으며 다양한 시설작물에서 직접적인 섭식 피해 이외에 토마토반점위조바이러스(TSWV)를 매개하는 간접적인 피해도 유발한다. 그동안 총채벌레 방제는 살충제에 의존해 왔는데, 이는 농업환경에 많은 부작용을 유발하고 해충의 저항성을 유발시켜 더욱 방제를 어렵게 하고 있다. 이러한 문제를 해결할 수 있는 대안으로 내성 회피를 위한 물질을 탐색하였다. 실내검정으로 약용작물 67종의 추출물을 꽃노랑총채벌레 성충에 처리하여 가장 효과가 우수한 목단피를 선발하였다. 목단피 추출물을 처리 후 1일차에 100%의 살충효 과를 보였다. 또한, 목화진딧물은 3일차 83%, 복숭아혹진딧물 3일차 97%, 점박이응애 1일차 100%의 살충효과를 보였다. 고추 포트 검정에서 꽃노랑총채벌레 방제가는 1일차 77.6%, 2일차 40%의 효과가 나타났다. 현재 추가적으로 효과를 증대시킬 수 있는 물질을 탐색하고 있으며, 총채벌레 방제에 본 추출물을 활용한다면 효과적일 것으로 기대된다. In addition to causing direct feeding damage to a variety of greenhouse crops, Frankliniella occidentalis also inflicts indirect harm by facilitating the transmission of the tomato spotted wilt virus. Historically, the prevention of F. occidentalis infestations has relied heavily on pesticide use. However, this approach has led to significant side effects in agricultural ecosystems, including the development of pest resistance and challenges in effective prevention. In response to these issues, research has been directed towards identifying alternative substances that circumvent the tolerance developed against chemical pesticides. Extracts from sixty-seven medicinal plants were prepared by soaking them in water for 24 hours at room temperature. These extracts were then applied to adult F. occidentalis, with particular attention to moutan extract treatment. This treatment demonstrated a 100% insecticidal effect on the first day. The moutan extract, specifically, was prepared using 50% ethanol, after which the ethanol and water were removed via a rotary evaporator. The resultant product was then lyophilized into a powder and used after being diluted with water. In indoor experiments, a 40% diluted solution was sprayed onto F. occidentalis, exhibiting a 100% insecticidal effect 24 hours post-treatment. Furthermore, a pot test indicated a 78% insecticidal effect on the first day of application. Ongoing research includes the analysis of active substances that demonstrate exceptional insecticidal properties and the conduct of on-site validation tests. The application of the aforementioned extract is anticipated to be effective in the prevention of F. occidentalis infestations.

Obesity increases the risks of diabetes, hypertension, and cardiovascular diseases, ultimately contributing to mortality. Korean Society for the Study of Obesity (KSSO) was established to improve the management of obesity through research and education; to that end, the Committee of Clinical Practice Guidelines of KSSO reviews systemic evidence using expert panels to develop clinical guidelines. The clinical practice guidelines for obesity were revised in 2018 using National Health Insurance Service Health checkup data from 2006 to 2015. Following these guidelines, we added a category, class III obesity, which includes individuals with body mass index (BMI) ≥35 kg/m2. Agreeing with the International Federation for the Surgery of Obesity and Metabolic Disorders, Asian Pacific Chapter consensus, we determined that bariatric surgery is indicated for Korean patients with BMI ≥35 kg/m2 and for Korean patients with BMI ≥30 kg/m2 who have comorbidities. The new guidelines focus on guiding clinicians and patients to manage obesity more effectively. Our recommendations and treatment algorithms can serve as a guide for the evaluation, prevention, and management of overweight and obesity.

본 연구는 대학생을 대상으로 사회적 지지와 자기지각의 관련성을 알아보기 위한 것이다. 이 목적을 위해서 대학생 319명이 회적 지지와 자기지각에 관한 문항에 응답하게 하였다. 연구결과 대학생의 사회적 지지척도는 대학생의 긍정적인 자기지각을 형성하는데 중요한 요인으로 밝혀졌으며 사회적 지지요소는 정서적 지지, 평가적 지지, 정보적 지지, 물질적 지지로 나누어 살펴보았다.
