The purpose of this study estimated whether a life style and diet pattern or natural phenomenon induced to aging in changes of plasma lipid component. Also, It was estimated from the changes of plasma lipid component followed acute maximal swimming exercise in different aged rats. Three months, nine months and sixteen months male rats of a Sprague-Dawley were housed in individual cages, and they were separated into each two group. - 3 month (12) : Control (6) and Experimental (6) - 9 month (22) : Control (10) and Experimental (12) - 16 month(16) : Control (8) and Experimental (8) In the 3.9.16 month, half of control group was randomly sacrificed. The other half of experimental group was performed with swimming exercise until exhaustive state. Water tank of 50cm depth and 50cm diameter was used for this study. Rats were given a 5 min warm up with swimming exercise, this warm up was followed by taking 5 min rest period, then animal exercised until exhaustion. Plasma cholesterol, HDL, LDL and TG levels followed aning of 3,9 and 16 months was not shown a significant difference between control group. Also, Plasma cholesterol, HDL and LDL levels of experimental group was not displayed statistically significant difference between 3,9 and 16 month group, but there was a significant difference(p<.05) between control and experimental group of 16 month, and between experimental group of 3 month and 16 month(p<.05) in levels of triglycerides. Conclusively, This study suggested that changes of plasma lipid component induced by aging was not phenomenan due to increase of age, and conditions except for life style and diet patern, etc. was similar to a changes of lipid component induced as exercise.

목적 : 의료기관의 범유행 인플루엔자에 대한 효과적인 대비를 위한 훈련방법으로서 의료기관-바탕 탁상훈련 (hospital based tabletop exercise)의 유용성과 순응도를 평가하기 위해서 시행되었다. 재료 및 방법 : 탁상 훈련은 부산대학교 병원에서 시행되었으며 병원의 주요의사결정권자 및 주요부서 대표자, 실무자 42명이 지휘부, 진료부, 지원부 3그룹으로 나뉘어 훈련에 참가하였다 탁상훈련의 시나리오는 의료기관의 자체 훈련을 위해서 고안하였으며 현재 동남아에서 유행하고 있는 H5N1 인플루엔자가 국내에 처음으로 유입되어 확산되는 과정에서 의료기관에서 발생할 수 있는 상황을 3가지 모듈로 구성하였다. 훈련 평가는 훈련 전후에 각각 익명의 설문조사를 시행하였다. 결과 : 훈련에 초청된 참여자 42명 중 37명(88%)이 실제 당일 훈련에 참여하였다. 훈련에 참여한 37명의 직원 중에서 훈련 전 시행한 설문에 27명(73%)이 응답하였다. 훈련 전 정가에서는 훈련을 통해 획득하고 싶은 지식이나 기술의 우선 순위를 물었으며, 참여자들이 가장 중요하다고 생각하는 항목은 대유행인플루엔자 바이러스에 대한 지식 향상 22%, 병원 각 부서가 취해야 할 계획 및 의사소통과 관련된 지식 향상 19%, 지역사회 병원들 간의 상호협력을 향상시킬 전략 계발이 19%이었다. 그룹토의 동안에는 환자의 조기 발견 이후 대응에 대한 토론이 많았지만, 구체적인 부분이 미흡하였고, 대유행 인플루엔자에 대한 기본적인 이해가 부족하였다. 훈련에 참여한 37명의 직원 중에서 훈련 후 시행한 설문에 21명(57%)이 응답하였다. 훈련 후 평가에서 탁상훈련의 전반적인 만족도에 대한 질문에서 81%가 만족하였다고 답변을 하였고, 새로운 것을 배우는데 유용했는가 대한 질문에도 86%가 유용했다고 답변하였다. 결론 : 탁상훈련은 의료기관의 대유행인플루엔자 대비에 효과적인 훈련방법이라고 생각되며 훈련을 통해 의료기관 내의 여러 부서들이 각 의료기관의 특성에 맞는 현실적이고 실제적인 대비 계획을 수립하는데 도움을 줄 것으로 기대된다. 그러나 향후 토른 촉진, 구체적인 결과에 도달을 유도할 수 있는 질문, 끼워넣기 개발, 적절한 시간 등에 대한 연구가 필요할 것으로 생각된다. Background : To evaluate the usefulness and compliance of a hospital-based tabletop exercise in setting of pandemic influenza in hospitals. Materials and Methods : Tabletop exercise was held in Pusan National University Hospital and forty two hospital employees were invited to participate in the exercise. The scenario for hospital-based tabletop exercise was designed. It consisted of three modules, which simulated the influx and outbreak of H5N1 influenza that was epidemic in Southeast Asia. Pre-, post-exercise surveys were completed by anonymous questions. Results : Thirty-seven (88%) of 42 invited participants attended exercise. AII members of the administration group and the ancillary services group participated. But, only 77% members of the clinical services group participated. In pre-exercise survey, priorities of eight goals regarding skills and knowledge during exercise were inquired., The highest priorities pointed out by the respondents were "Increase the knowledge of pandemic influenza" (22%), "Development of strategies for optimal communication among employees within specific department" (19%) and "Development of strategies for improved coordination between facilities within the health system" (19%). Twenty-one (57%) of participants completed the post-exercise surveys. At post-exercise surveys, 81% of the participants stated that the tabletop exercise was extremely or very useful, 86% of the participants also stated that it increased their knowledge of pandemic influenza. Conclusion : Tabletop exercise is an effective modality for increasing pandemic influenza preparedness in hospitals, and this method is useful for guiding preparedness activities within the hospital environment. Further studies to determine the appropriate method of discussion, questionnaire, duration of exercise and injection are needed.

The present study evaluated the susceptibility of field populations of Plutella xylostella and Spodoptera exigua larvae to four diamide insecticides—chlorantraniliprole, cyantraniliprole, cyclaniliprole, and flubendiamide. All the four diamide insecticides induced 100% mortality in the populations from Seongju (SJ) and Geochang (GC) when treated at a concentration recommended for P. xylostella. However, a very low insecticidal activity was observed in the population from Pyeongchang (PC) with 42.3% 3 d after treatment with chlorantraniliprole. Further, the populations of S. exigua from Cheongju (CJ), Jindo (JD), and Yeonggwang (YG) were not completely controlled by the 4 diamide insecticides. A comparison of susceptibility of S. exigua larvae to chlorantraniliprole between 2014 and 2017 showed that chlorantraniliprole induced 100% mortality in all populations in 2014, whereas a very low insecticidal activity was observed among the populations in 2017. This study can serve as a basis to control pests effectively using diamide insecticides.

The green peach aphid, Myzus persicae Sulzer, is an important sap-sucking pest of many plants, including Chinese cabbage. The objective of the present study was to determine the effects of sublethal concentrations of two insecticides (flonicamid and thiamethoxam) and the action mechanisms on the feeding behavior of M. persicae. The median lethal concentrations (LC50) of flonicamid and thiamethoxam for adult M. persicae were 2.56 and 4.02 mg/L, respectively. The sublethal concentrations of flonicamid were 0.44 mg/L (LC10) and 1.25 mg/L (LC30), and those of thiamethoxam were 1.19 mg/L (LC10) and 2.45 mg/L (LC30). The developmental period of M. persicae nymphs was 5.9 days at LC10 and 6.1 days at LC30 for both insecticides compared to 5.7 days for the control. Adult longevities at LC10 and LC30 of flonicamid were 13.2 and 13.7 days, respectively. Adult longevity at LC10 of thiamethoxam was 14.7 days. Control adult longevity was 11.6 days. Total fecundity was higher at LC10 (41.8 offspring/female) and LC30 (43.0 offspring/ female) of flonicamid, and at LC10 (42.1 offspring/female) of thiamethoxam than that of the control (29.5 offspring/female). Feeding behavior analysis using an electrical penetration graph showed that sublethal doses of flonicamid and thiamethoxam had significant effects on the duration of phloem ingestion. However, higher doses of flonicamid induced starvation by inhibition of phloem ingestion and higher doses of thiamethoxam induced contact toxicity rather than inhibition of feeding behavior. This study provides the basis for a more efficient use of these pesticides in Korea.

This study was performed to investigate the effect of flonicamid and thiamethoxam treated at sublethal concentration (LC10, LC30) on development period, adult longevity and fecundity and the feeding behaviour of Myzus persicae adult. Developmental period of M. Persicae nymph took 5.9 days in LC10, and 6.1 days in LC30 in both insecticides, comparing with control (5.7 days), it showed longer than those of the control, but there was no significance. Adult longevity treated at LC10 and LC30 of flonicamid was showed 13.2 and 13.7 days, respectively, and LC10 of thiamethoxam was examined as 14.7 days, it showed longer than control of 11.6 days. Mean daily fecundity exhibited higher in LC10 (3.1) and LC30 (3.1) of flonicamid than that of control (2.5), but thiamethoxam are not. Total fecundity exhibited higher in LC10 (41.8) and LC30 (43.0) of flonicamid, in LC10 (42.1) of thiamethoxam than that of control (29.5). Feeding behavior was examined using EPG (electrical penetration graph). EPG data indicated that flonicamid and thiamethoxam increased the duration of non-probing periods and decreased the duration of phloem ingestion.

The green peach aphid, $Myzus$ $persicae$ S$\ddot{u}$lzer, is an important sap-sucking pest of many plants, including Chinese cabbage. The objective of the present study was to determine the effects of sublethal concentrations of two insecticides (flonicamid and thiamethoxam) and the action mechanisms on the feeding behavior of $M.$ $persicae$. The median lethal concentrations ($LC_{50}$) of flonicamid and thiamethoxam for adult $M.$ $persicae$ were 2.56 and 4.02 mg/L, respectively. The sublethal concentrations of flonicamid were 0.44 mg/L ($LC_{10}$) and 1.25 mg/L ($LC_{30}$), and those of thiamethoxam were 1.19 mg/L ($LC_{10}$) and 2.45 mg/L ($LC_{30}$). The developmental period of $M.$ $persicae$ nymphs was 5.9 days at $LC_{10}$ and 6.1 days at $LC_{30}$ for both insecticides compared to 5.7 days for the control. Adult longevities at $LC_{10}$ and $LC_{30}$ of flonicamid were 13.2 and 13.7 days, respectively. Adult longevity at $LC_{10}$ of thiamethoxam was 14.7 days. Control adult longevity was 11.6 days. Total fecundity was higher at $LC_{10}$ (41.8 offspring/female) and $LC_{30}$ (43.0 offspring/female) of flonicamid, and at $LC_{10}$ (42.1 offspring/female) of thiamethoxam than that of the control (29.5 offspring/female). Feeding behavior analysis using an electrical penetration graph showed that sublethal doses of flonicamid and thiamethoxam had significant effects on the duration of phloem ingestion. However, higher doses of flonicamid induced starvation by inhibition of phloem ingestion and higher doses of thiamethoxam induced contact toxicity rather than inhibition of feeding behavior.

Sun-Ran Cho,Changmann Yoon,Hyun-Na Koo,Gil-Hah Kim 한국응용곤충학회 2011 한국응용곤충학회 학술대회논문집 Vol.2011 No.10

This study was performed to evaluate the contact toxicity and residual toxicity of the 26 commercially registered insecticides against cigarette beetle, Lasioderma serricorne and maize weevil, Sitophilus zeamais adult. Among 26 insecticides, seven insecticides (chlorpyrifos, chlorpyrifos-methyl, fenitrothion, fenthion, phenthoate, cypermethrin, α-cyhalothrin) against L. serricorne adult and five insecticides (chlorpyrifos, chlorpyrifos-methyl, fenitrothion, fenthion, phenthoate) against S. zeamais adult showed perfect mortality. LC50 (ppm) values of those selected insecticides were appeared lowest value on α-cyhalothrin (1.46 ppm) against L. serricorne adult and chlorpyrifos-methyl (0.64 ppm) against S. zeamais adult, respectively. However, chlorpyrifos-methyl still remain high toxicity until 90th days after treatment against both L. serricorne and S. zeamais adults. From above results, it will be useful information to select insecticides effective against L. serricorne and S. zeamais adults.
