관주처리에 의한 벼멸구 흡즙 섭식 독성, 잎 침지처리에 의한 접촉독성과 식물체내 침투에 의한 섭식독성, 미량국소처리에 의한 표피 접촉 독성 등, 처리 방법에 따른 카보퓨란의 벼멸구에 대한 살충 작용 특성을 분석하였다. 카보퓨란 관주처리는 시간에 따른 벼멸구의 살충력 변화가 2가지 패턴으로 나타났다. 상대적으로 높은 농도(8~30 ppm)의 처리에서는 급격히 사충율이 올라가다가 시간이 지남에 따라 증가율이 낮아지는 로그곡선의 형태와 낮은 농도(1~4 ppm)의 처리에서는 사충율 증가 패턴이 S 자 모양의 곡선 형태를 보였다. 관주처리 시 높은 농도에서는 처리효과가 즉시 나타나 하루 만에 치사율이 40% 이상 도달하였으나 상대적으로 낮은 1~2 ppm의 농도에서는 처리 5일 후에야 80~100%에 달하는 사충율을 얻을 수 있었다. 침지처리는 사충율이 처리 1일 후 약효가 급격히 증가하고 이 후 증가율이 낮아졌다. 국소처리도 침지처리와 비슷한 경향을 보이나 침지처리와는 달리 처리 후 3일 이후에는 사충율이 거의 증가하지 않았다. 약효 최적 조사 시간은 관주처리에서 처리 후 2일 (42시간)이었으며 침지처리와 국소처리에서는 처리 후 1~2일이 약효 조사 적기였다. For determining the insecticidal effect of Carbofuran on the Brown planthopper, Nilaparvata lugens, sucking toxicity by drenching application, sucking and contact toxicity by leaf dipping application, and contact toxicity by topical application were examined. Drenching caused two types of mortality patterns. One was logarithmic curve at a relatively high concentration (8~30 ppm) with over 40% mortality in 24 h, and the other was an S-shaped curve at low concentrations (1~4 ppm) with over 60% mortality on the fifth day after Carbofuran treatment. Leaf dipping application caused a rapid increase in mortality in a day, and this effect decreased steadily with time. Topical application showed steep increase in mortality in a day, and hardly increased thereafter. The best mortality evaluation time for the drenching application was the second day (42 h), and that for the leaf dipping and topical applications was the first or second day after Carbofuran application. When the insecticide has systemic effects, drench application provides the best efficacy and its insecticidal effects persist for a longer time than any other application method.

Background : Sasang Constitutional Medicine (SCM) is the field of traditional Korean medicine that emphasize four constitutional types for diagnosis and treatment. Appearance, personalities and pathological characteristics are main factors of Sasang constitutional classification. Previous studies carried out by the pulse analyzer showed that the pulse wave can discriminate these types. In addition, It was reported that the pulse wave are affected by age and sexuality. In this study, we investigated the pulse wave chatacteristics related Sasang constitution types in control group regarding their age and sexuality. Subjects and Method : Two hudred and eighteen volunteers participated in this study: healthy men in 20~49 years old. Participants were interviewed and examined to evaluate their health condition and Sasang constitution type. Then they were tested with pulse analyzer when they ere stabilized. The pulse at the radial artery just beside styloid process was measured, because this area is landmark for pulse diagnosis in oriental medicine. 3-D Mac pulse analyzer (Daeyo Medi Co. Ansan. Korea) was used in this study. We analyzed main features of pulse waves with the Sasang condtitution types by the SPSS for Windows (ver 12.0). Results : There was significant difference between Taeum and other types in contact pressure as well as in coefficient of floating and sinking pulse. Conclusion : By analyzing pulse waves of healthy adult men, we found significant differences exist between Taeum and other types. These pulse differences may characterize Taeum type, and it will be helpful for the evaluation of Taeum type.

Objectives : In this study, we diagnosed Mibyeong group of adult by taking into Mibyeong Index consideration, and identified the correlation of a Mibyeong group with cold-heat pattern and life quality of them. Methods : The questionnaires were collected by Gallup Korea professional surveyor through face to face interviews. To analyze the differences between health and mibyeong group, we used the descriptive statistics, Pearson's correlation, ANOVA. And multinomial logistic regression was used to generate the odds ratios (ORs) and 95 % confidence interval (CI) for the differences between health and mibyeong group. Results and Conclusions : The gender composition of respondents in this study that there 545 male (49.5%) and 555 female (50.5%). The score of both cold pattern(health: $21.33{\pm}4.25$, MI 1: $22.43{\pm}4.29$, MI 2: $24.09{\pm}5.03$; post hoc test, p <0.001) and heat pattern(health: $18.4{\pm}4.01$, MI 1: $19.48{\pm}4.10$ MI 2: $19.88{\pm}4.81$; post hoc test, p <0.001) in mibyeong group is higher than the score health group. And, these result have no relevance to age. The score of both Physical component summary (PCS) and Mental component summary (MCS) in health group is higher than the score mibyeong group. Cold-heat pattern and quality of life vary significantly according to health status. This results suggest the analysis of cold-heat pattern and quality of life by health status could provide the setting of direction to promote public health depending on health status.

Background According to the Sasang constitutional medicine, eating habits according to the characteristics of Sasang Constitution (SC) types affect management of chronic diseases and health conditions. The aim of this study is to identify the association between eating habits, such as breakfast, eating frequency, and energy intake, according to SC, and quality of life. Method This study is a cross-sectional study of people aged 33 to 55 years, sampled by stratification based on population distribution. The SC types were classified into Taeeumin (TE), Soeumin (SE), and Soyangin (SY) using a structured questionnaire (KS-15). Items examined regarding eating habits were whether the subjects had breakfast; the frequency of eating such as breakfast, lunch, dinner, and after-dinner snacks; and energy intake surveyed using a food frequency questionnaire. As for quality of life, SF-12, which is widely used worldwide to assess health conditions, was utilized. A regression analysis was conducted on the relations between eating habits according to SC and quality of life. Results The SC distribution of the 3,895 subjects was 47% for TE, 22% for SE, and 31% for SY. The scores indicating quality of life differed for TE and SY depending on whether they ate breakfast and eating frequency groups, and those of SE varied depending on levels of energy intake. A regression analysis having adjusted all covariates demonstrated for TE a positive relation between the eating frequency of three times per day or more (compared to 1.5 to 3 meals per day) and quality of life (B=1.365, p<0.001). For SE, there was a negative association between low energy intake (compared to adequate energy intake) and quality of life (B=-1.642, p=0.004). Meanwhile, no relation was found between eating habits and quality of life for SY. Conclusion This study identified the association between eating habits according to SC types and quality of life. For TE, it was found to be important to eat evenly dispersed adequate amounts as opposed to overeating or binging at once. For SE, adequate energy intake affected good quality of life. This study suggests that eating habits based on SC improve quality of life, and health management customized for each constitution should be performed in the future through proper eating habits.
