        In the previous study, the plant essential oils such as clove bud , thyme white and garlic oils gave potent toxicity with the range of 1.5 to 4.5×10-3 ul cm-3 of LC50 values against Bemisia tabaci. Based on the bio-assay results, three plant essential oils(clove bud, thyme white and garlic) were applied to 30% emulsion type. The 100, 200 and 400 fold dilution of these emulsions was showed mild toxicity under port scale treatment against Q biotype. At each fold dilution, clove bud showed 44, 26 and 14%, and thyme white produced 44, 39 and 27%, respectively. Of garlic emulsion, its toxicity was evaluated with 27, 26 and 11%, respectively. But, in case of clove bud and thyme white mixture, their toxicity was more good under the mixture than under the single treatment. Mixture with clove bud 200 fold dilution adding to thyme white 200 fold dilution showed potent activity with 86% mortality. And also 200 adding to 400, and 400 to 400 exhibited 61%, 76%, respectively. These essential oil mixtures showed similar strong toxicity against B biotype under port scale test. In particular, the mixture with clove bud 200 fold dilution adding to thyme white 200 fold dilution showed the highest synergistic effect. Toxicity to plants, except the 100 fold dilution of these emulsions was not observed.

        The bean bug, Riptortus pedestris (=clavatus) Fabricius (Hemiptera: Alydidae) is a serious pest of soybean in many countries. It enters a reproductive diapause in the winter by short day length (<13.5 h.) in Korea and Japan. The combined effects of temperatures (25℃ and 8℃) and day lengths (10L:14D and 14L:10D) upon the termination of the male"s diapause were studied. The combinations are ① HTLD = 25℃, 14L:10D treatment for 1, 2, 3 weeks and 30 days, ② HTSD = 25℃, 10L:14D treatment for 1, 2, and 3 weeks, ③ LTLD→HTLD = 8℃, 14L:10D treatment for 1, 2, and 3 weeks followed by HTLD treatment, ④ LTSD→HTLD = 8℃, 10L:14D treatment for 1, 2, and 3 weeks followed by HTLD. The amount of aggregation pheromone components secreted was adopted as the criteria for diapause termination in males. Males did not secrete aggregation pheromone under HTSD conditions. However, the males treated with HTLD for more than 21 days secreted significantly higher amounts of aggregation components, (E)-2-hexenyl (Z)-3-hexenoate and (E)-2-hexenyl (E)-2-hexenoate, compared to the control or HTSD treatments. The three components of the aggregation pheromone were secreted by the 14%, 29%, and 100% males treated with HTLD for 7 days, respectively. However more than 83% of the HTLD-treated males secreted all three components by the 30<SUP>th</SUP> day under the treatment. In comparison, the pheromone amounts secreted by the males treated with LTLD→HTLD or LTSD→HTLD were equal or less than those secreted by males with continuous HTLD treatment.

        Purpose : In order to verify using Convergence Insufficiency Symptom Survey(CISS) is proper method to distinguish convergence insufficiency(CI) group and normal binocular vision(NBV) group in adults. Methods : 97 subjects 19 to 35 with normal VA and no strabismus participated in this study. Phoria, positive fusional vergence(PFV), nearpoint of convergence(NPC) and accommodation convergence/ accommodation(AC/ A) of 97 were measured. Results : According to criteria, 62 subjects were included in this study and analysed with CISS. Nine subjects had CI and 53 had NBV. General symptoms of CI group were significantly greater occurrence of Jose concentration, tiredness, sleepiness, uncomfort, double vision and blurring in that order. A significant difference between CISS seore of CI subjects (mean±SD: 25.67±7.67) and NBV group(l2.74 ±4.80) were found(p=O.OOO). The area under the ROC curve was 0.955 indicating outstanding discrimination using the CISS. Using seores of 21 or higher to denote CI, a sensitivity of 88.9% and specificity of 98.1% were obtained. Conclusions : The results suggest that the CISS is a valid instrument for differentiating adults with symptomatic CI from those with symptomatic NBV. Adopting score 21 as cutoff value, it is proved that distinguishing Cl from normal is most precise. Additionally, Adults in this age group were able to respond to a broad range of symptom questions associated with CI. It. therefore, demonstrates CISS is a valid preliminary examination to scan CI patient.

        The bean bug, Riptortus clavatus Thunberg (Hemiptera: Alydidae), is a pest of soybeans and tree fruits. It enters reproductive diapause during winter. We studied the effect of different combinations of temperature, day length, and treatment period on the termination of diapause in R. clavatus using adult females collected in October and November 2006. Ovarian development was used to determine diapause termination. The treatments were: ① HTLD, 25℃, 14L:10D treatment for 1, 2, 3 weeks and 30 days, ② HTSD, 25℃, 10L:14D treatment for 1, 2, and 3 weeks, ③ LTLD, 8℃, 14L:10D treatment for 1, 2, and 3 weeks followed by HTLD for 3 weeks, and ④ LTSD, 8℃, 10L:14D treatment for 1, 2, and 3 weeks followed by HTLD for 3 weeks. The HTSD treatments did not affect ovarian development, and resulted in no significant difference in the number of mature eggs in ovaries or the percentage of diapause-terminated females compared to the control females before treatment. The percentage of females that terminated diapause was significantly higher in the HTLD treatment than in the HTSD treatment. The HTLD treatment for more than 14 days increased the percentage of diapause-terminated females, accelerated the development of the ovaries, and increased the number of mature eggs in ovaries. Compared with the HTLD or HTSD treatments, the LTLD or LTSD treatments followed by the HTLD treatment accelerated ovarian development and increased the number of ovipositing females. The pre-LTSD treatment for 1 week was enough to increase the number of eggs oviposited.

        Origanum essential oil [Origanum acutidens (Hand.-Mazz.)] showing insecticidal activity and repellency against red flour beetle, Tribolium castaneum (Coleoptera: Tenebrionidae) adults was analysed by GC-MS. All constituents of the oil were identified, and the main components were carvacrol (67.2%), p-cymene (16.2%), γ-terpinene (5.5%), thymol (4.9%),and linalool(2.1%). In vapor phase fumigant assay, the origanum oil was more effective in closed condition (LD50 = 0.555 mg/cm3) than in open one (LD50 = 0.353 mg/cm3).This result suggests that the toxicity of the oil to red flour beetle is exerted largely by vapor phase. Based on 24-h LD50 values, the toxicity of caryophyllene oxide (0.00018 mg/cm3) was comparable with that of dichlorvos (0.00007mg/cm3) as a positive insecticide. In addition, thymol, camphene, α-pinene, p-cymene, and γ-terpinene gave good insecticidal activity (LD50 = 0.012 - 0.195 mg/cm3). In repellent test using 9 constituents of origanum oil, caryophyllene oxide showed 100% repellent activity at 0.0158 and 0.0032 mg/cm2. These results indicate that the origanum oil and its some components could be potential candidates as a fumigant and repellent for managing T. castaneum adults. Potential molecular target of repellents will be discussed.

        This study was performed to investigate the escape of pine wood nematode (PWN), Bursaphelenchus xylophilus, from two vector species (Monochamus alternatus and M. saltuarius) through oviposition and feeding behavior. First, we checked number of PWNs escaped from M. alternatus emerged from three different cases of pine logs. In case A, healthy pine trees were cut into logs and left in pine forest infected with PWN. In case B, healthy pine trees were cut into logs, left in large screen cage, and let them oviposited by M. alternatus emerged from pine trees infested with PWN. In case C, pine trees which were harboring M. alternatus were cut into logs, and PWN was inoculated artificially. The M. alternatus adults emerged from the above three cases of pine logs were checked in the next year to know how many PWN they were harboring in their bodies. The percentages of M. alternatus harboring PWN (18.3 and 15.6%, respectively) and number of nematodes per vector (5,713.1±9,248.3 and 2,034.1±4,746.8 PWNs, respectively) in case A and B logs are similar to each other. However, the percentage and the number in case C (38.3% and 20,083.1±32,188.3 PWNs) were higher than those of case A and B. Among 52 M. alternatus adults harboring PWN from all the three cases, 20 adults (38.5%) were harboring more than 5,000 PWNs per beetle. And these 20 adults were harboring 97.9% of the total PWNs in 52 adults. Second, we checked the daily escape of PWNs from M. alternatus and M. saltuarius collected at pine forest infested with PWN. The PWN escaped from their vector body for 34.9±12.4 days for M. alternatus, and for 23.9±16.2 days for M. saltuarius, reaching at peak escape during the 2nd week of emergence of the two vector species. A 44.5 and 47.2% to the total PWNs escaped from vector body within 2 weeks of vector emergence for M. alternatus and M. saltuarius, respectively. The number of PWNs escaped from each vector was 3,570.6±5,189.2 and 1,556.2±1,710.3 for M. alternatus and M. saltuarius, respectively.

        One hundred seven plant essential oils were tested for insecticidal activities against Bemisia tabaci B and Q biotype adults, using the fumigation and direct spray methods. In the fumigation assay with the Q biotype adults, garlic oil was the most toxic (1.5×10-3 μl/cm3) on the basis of the LC50 value. Clove leaf, thyme, oregano (origanum), clove bud, savory, cinnamon bark, dabana, vetiver haiti and catnip essential oils also gave potent toxicity with the range of 1.7 to 4.5×10-3 μl/cm3 of LC50 values. These essential oils showed similar strong toxicity against B biotype. Based on the results obtained from fumigation test, nine plant essential oils were selected for the direct spray application at three concentrations (0.5, 0.1 and 0.02%). A litter difference was obtained between B and Q types in mortality to the tested oils. At the 0.5% concentration, they gave considerable mortality of 76 to 100%. At 0.1%, only garlic essential oil produced 96 to 100% mortality, but the others showed less than 76% mortality. Several plant essential oils appear to be candidates for the control of B. tabaci.

        The acaricidal activities of Illicium verum fruit-derived materials against adults of Dermanyssus gallinae were examined using the direct contact application method. Based on laboratory tests, an acaricidal constituent of I. verum fruit was determined because of its potent activity. Results were compared with those of the currently used acaricides such as dichlorvos, diazinon, and carbaryl. The acaricidal principle of I. verum fruit was identified as (E)-anethole using a GC-MS. Its acaricidal activity was compared with those of 12 compounds having a similar chemical moiety. Based on the LD50 values, the acaricidal activities of (+)-or-(–)-neomenthol were the strongest (0.01 ㎎/㎠]) and (E)-anethole, (+)-or-(–)-menthol, (±)-isoborneol, (–)-menthone, and (1S)-endo-(–)-borneol showed similar results (0.02 ㎎/㎠), and (1R)-(+)-camphor and (+)-menthone also gave good activities (0.03 and 0.04 ㎎/㎠, respectively). These compounds showed more toxic acaricidal activities than diazinon and carbaryl, 0.05 and > 0.2 ㎎/㎠, respectively, but were not comparable to that of dichlorvos with 0.0002 ㎎/㎠. These results indicate that the I. verum fruit-derived materials and tested compounds descried as poultry red mites-control agents could be useful for managing field populations of D. gallinae.

        The purpose of this study was to assess the peak plantar pressure distribution under foot areas according to the height of heel lifts in obese adults and non-obese adults during walking. Thirty-one participants volunteered for this experiment. The average body mass index (BMI) value of the fourteen subjects in the obese group was 26.5±1.4 ㎏/㎡ (from 25.1 to 29.3 ㎏/㎡), and of seventeen subjects in the non-obese group was 20.0±1.1 ㎏/㎡ (from 18.7 to 22.7 ㎏/㎡). The subject ambulated while walking in the sneakers, walking with 2 cm heel lifts, and walking with 4 cm heel lifts in the shoes. We measured the peak plantar pressure under the hallux, 1st, 2nd, 3~4th, and 5th metatarsal head (MTH), mi foot, and heel using F-scan system. The obese group had significantly higher peak plantar pressure under all foot areas than the non-obese group regardless of the height of heel lifts (p<.05). The peak plantar pressure under the 5th MTH and heel was significantly decreased, also the peak plantar pressure under hallux, 1st, and 2nd MTH was significantly increased according to the height of heel lifts in the obese group and non-obese group (p<.05), We proposed that individuals with heel lifts in shoes should be careful, as there is high plantar pressure under the forefoot.

The chestnuts infected by the weevils were collected from Gongju, Buyeo, and Cheongyang in Chungnam Province, Republic of Korea. Investigation was focus on the escape period of chestnut weevil larvae from the fruits, invading time and vertical distribution in soil, survival rates of larvae during overwintering, emergence period, emergence rate, and sex ratio and longevity of adults. For precocious species, larvae escaped the chestnut from the mid-September to the early-October, middle species and slow species, were escaped from the late-September to the mid-October and from the early-October to the mid-November. After escaping from the chestnut fruits all of the larvae burrowed into the soil within 35 minutes. Overwintering larvae inhabited in the range of 0~48 ㎝ from the soil surface and highly distributed in the range of 18~36 ㎝. The 74.1% of wintering chamber were distributed within 18~36 ㎝ from the surface. Survival rates observed were 38.0% in 1st year, 16.0% in 2nd years, and 2% in 3rd years, respectively. Seasonal occurrence period of C. sikkimensis was from the early-Aug. to early-Oct. and the optimal occurrence period was the early and mid-Sept. Emergence rate decreased to 8.4% in 1st year, 3.6% in 2nd years, and 0.8% in 3rd years, respectively. Sex ratio was showed in the range of 0.51-0.55. It is female biased ratio. Longevity of adults was 9.9 days for female and 8.9 days for male.

        The purpose of this study was to measuring the causal relationships among food involvement, health, mood, convenience, sensory appeal, weight control and vegetable consumption. A total of 290 questionnaires were completed. Structural equation model was used to measure the causal relationships among constructs. Results of the study demonstrated that the structural analysis result for the data also indicated excellent model fit. The effects of food involvement on health, mood, convenience, sensory appeal, weight control and vegetable consumption were statistically significant. As expected, health, mood, sensory appeal and eight control had significant effects on vegetable consumption. Moreover, health, mood, convenience, sensory appeal and weight control played mediating roles in the relationship between food involvement and vegetable consumption. In conclusion, based on structural analysis, a model was proposed of interrelations among food involvement, health, mood, convenience, sensory appeal, weight control and vegetable consumption. It should be noted that the original vegetable consumption model was modified and should, preferably, be alidated in future research. Other variables, such as attitude, subjective norm and perceived behavior control, may be incorporated to form vegetable consumption models that consist of new antecedent and consequence pairs.

        This study investigated gait characteristics, kinematics, and kinetics in the lower extremities between two different shoe conditions (high heeled shoes (7 cm), and high heeled shoes with a total contact insert (TCI)) after lower extremity muscle fatigue. Although TCI shave been applied in high heeled shoes to increase comfort and to decrease foot pressure, no study has attempted to identify the effects of TCI in fatigue conditions. The purpose of this study was to determine the effects of walking in high heeled shoes with TCI after lower extremity muscle fatigue was induced. This study was carried out in a motion analysis laboratory at Hanseo University. A volunteer sample of 14 healthy female subjects participated. All in fatigue conditions, the subjects were divided into two groups. The muscle fatigue was induced by 40 voluntary dorsi- and plantar-flexion exercises and 40 heel-rise exercises of the dominant foot. Surface electromyography was used to confirm the localized muscle fatigue using power spectral analysis of three muscles (tibialis anterior, gastrocnemius medialis and lateralis). The results were as follows: (1) In muscle fatigue conditions, the use of TCI decreased the peak flexion angle of the hip joint significantly in the early stance phase (p<.05) and increased the peak hip flexion moment in the terminal stance phase (p<.05). (2) In muscle fatigue conditions, the application of TCI also increased peak hip power generation in the early stance phase and peak hip power absorption in the terminal stance phase (p<.05). (3) In muscle fatigue conditions, the use of TCI reduced the impact force significantly and increased the secondary peak vertical GRF. These findings suggest that the TCI may provide beneficial effects when muscle fatigue occurs for a high heeled shoe gait. Future research employing the patient population and various types of TCI materials are required to clarify the effects of TCI.
