The effects of some essential oils and Sopophora extract on Frankliniella occidentalis adults, Myzus persicae adults, Plutella xylostella larvae, and Spodoptera exigua larvae were investigated. Insecticidal and phytotoxicity activities of emulsion in water formulations containing the active essential oils as active ingredients under laboratory and pot conditions were also tested. Based on these results, NRS-13 and NRS-24 formulations were selected to further assess as follows; the GC and GC-MS analysis on the active essential oils, the quantity analysis of the major components contained in the formulations, their insecticidal activities under pot and field conditions, and their oral, dermal, skin and eye irritation, and fish toxicities. Thus, the NRS-13 (BaechooSaferTM) and NRS-24 (JindiOutTM) formulations could be considered as insecticides for pest control.

Bee pollen have been used for centuries as a kind of traditional medicine and food diets additive due to their nutritional and biological properties. The present study was to evaluate the biological features of ethanol extracts of 18 different bee pollen (EEBP) samples collected from 16 locations of South Korea. Our results indicated most of the EEBP samples showed 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, inhibitory activities against human β-amyloid precursor cleavage enzyme (BACE-1), and antiproliferative activities towards five cancer cell lines. However, these EEBP samples did not present human acetylcholinesterase (AChE) inhibitory activities, and intestinal bacteria growth inhibitory activities.

The American house dust mite, Dermatophagoides farinae Hughes, 1961 (Acari: Pyroglyphidae), is recognized as an important source of allergens in the domestic environment. An assessment was made of the toxicity of constituents from essential oil of cade, Juniperus oxycedrus L. (Cupressaceae), and related compounds as well as four experimental spray formulations containing the oil (10–40 g/liter sprays) to adult D. farinae. In a contact + fumigant mortality bioassay, methyleugenol (24-h LC50,5.82 μg/cm2) and guaiacol (8.24 μg/cm2) were the most toxic constituents to the mites and the toxicity of these constituents and benzyl benzoate did not differ significantly.

A key to the Korean species and illustrations of diagnostic characters are provided.

Despite the enormous ecological success of insects elsewhere on earth, they have failed to colonize oceans. A significant portion of the marine littoral insect fauna consists of Coleoptera and the highest number of species belongs to the beetle family Staphylinidae. At present, over 400 species in 91 genera and eight subfamilies are confined to marine coastal habitats. Coastal Staphylinidae are polyphyletic, and have diverse adaptations of structure, physiology, and behavior. Aleocharinae contain the largest number of coastal species (about 200 species in 46 genera). Today I would like to briefly introduce my research program on the diversity, phylogeny, habitat evolution, and historical biogeography of the coastal Aleocharinae. Three selected aleocharine lineages containing many coastal species published with my colleagues are provided.

The aim of the present study was to develop an animal model for evaluation of temporomandibular (TMJ) nociception under TMJ inflammation. We also investigated the participation of IL-1β in inflammation-induced TMJ nociception. Experiments were carried out using male Sprague-Dawley rats. Intra-articular injection of 3% formalin was administered to evaluate hyperalgesia 3 days after CFA injection. Intra-articular injection of 3% formalin did not produce nociceptive behavior in normal rats. Although intra-articular injection of 3 doses of CFA produced TMJ inflammation, only 1:3 diluted CFA produced hyperalgesia when formalin was injected intra-articularly 3 days after CFA injection. Co-administration of IL-1 receptor inhibitor with formalin into the TMJ cavity 3 days after CFA injection was performed. Co-administration of IL-1 receptor inhibitor significantly inhibited formalin-induced hyperalgesia in rats with CFA-induced TMJ inflammation. These results suggested that intra-articular injection of formalin produced hyperalgesia under chronic TMJ inflammation. Moreover, IL-1β plays an important role in TMJ hyperalgesia under chronic inflammation and blockade of IL-1β is a potential therapeutic target for inflammatory TMJ pain.

In this paper, we study the lunar eclipse records in the Goryeosa (History of the Goryeo Dynasty), an official history book of the Goryeo dynasty (A.D. 918 – 1392). In the history book, a total of 228 lunar eclipse accounts are recorded, covering the period from 1009 to 1392. However, we find that two accounts are duplications and four accounts correspond to no known lunar eclipses around the dates. For the remaining lunar eclipses, we calculate the magnitude and the time of the eclipse at different phases using the DE406 ephemeris. Of the 222 lunar eclipse accounts, we find that the minimum penumbral magnitude was 0.5583. For eclipses which occurred after midnight, we find that some accounts were recorded on the day before the eclipse, like the astronomical records of the Joseonwangjosillok (Annals of the Joseon Dynasty), while others were on the day of the lunar eclipse. We also find that four accounts show a difference in the Julian dates between this study and that of Ahn et al., even though it is assumed that the Goryeo court did not change the dates in the accounts for lunar eclipses that occurred after midnight. With regard to the contents of the lunar eclipse accounts, we confirm that the accounts recorded as total eclipses are accurate, except for two accounts. However, both eclipses were very close to the total eclipse. We also confirm that all predicted lunar eclipses did occur, although one eclipse happened two days after the predicted date. In conclusion, we believe that this study is very helpful for investigating the lunar eclipse accounts of other periods in Korea, and furthermore, useful for verifying the calendar dates of the Goryeo dynasty.

Pleurotus cornucopiae (PC) mushrooms is found in the field and commonly known in Japan as Tamogidake mushrooms. Recently it has been reported that PC also alleviating the toxicity of heavy metals. However little is known about mechanism of the action of PC on osteoblast differentiation, especially in transcription factor. Inhibitor of DNA binding-1 (Id-1) function has been linked to the proliferation, migration, and senescence of cells, and studies about relationship between Id-1 and biological function. Therefore, this study was aimed to investigate the effect of PC on osteoblast differentiation and expression of Id-1 and Id-2. PC treatment increased ALP, Col 1 and OCN. PC treatment up-regulated the mRNA levels of Id-1 and Id-2 genes. This PC–induced osteoblast differentiation is more effective in lower doses rather than high doses. This study shows that expression of Id-1 and Id-2 was increased in a dose-dependent manner during PC-induced osteoblast differentiation.

The purpose of this study was to analyze physiological reactions and visual preferences for lawn and flowerbed preferred by mental patients, and green space which is highly related with healing effects. Subjects were 25 mild cases of schizophrenia, who on the recommendation of their doctor, resided in psychiatric hospitals located in Jeollabuk-do, Korea. The survey was carried out in August 2010. The subjects were shown computer graphic simulations by a beam projector, and then brain wave and preferences were measured. In regards to physiological responses, the separate arrangement of tree cluster promoted a sense of stability and vitality, simultaneously. In the aspect of visual preferences, just one mass was preferred. The natural landscape planting pattern was visually preferred. There was a difference in preferences for the planting proportion of evergreen and deciduous trees in the leaf-fall and leaf-color seasons, but when both of them are taken into consideration, it is advisable that 75% of trees planted be occupied by evergreens to encourage emotional stability. The higher the ratio of tree to a lawn, the higher the visual preference. The ratio of 1:1 or 1:0.5 between a lawn and trees is advisable if the physiological effect is considered, but creating a lawn alone should be avoided. With regard to color preferences for the flower bed, orange was visually preferred. Pink was desirable to create a sense of emotional stability, and red to physiologically revitalize the subjects.

The two-spotted spider mite Tetranychus urticae is being steadily problematic on strawberry. To effective control of this pest, one combination application using predatory mite Phytoseiulus persimilis plus a pesticide Acequinocyl suggests. Prepared six beds (1.5 × 3 m; 20 strawberry plants) on glass house, 100 T. urticae was inoculated on per 20 plants. Four plots prepared - Acequinocyl treatment, P. persimilis application, Acequinocyl+P. persimilis double application, and the control. The change of T. urticae density was investigated in the seven-day intervals. In an Acequinocyl treated plot, T. urticae density was decreased after Acequinocyl sprayed, but began to increase steadily one month later. In a P. persimilis applied plot, T. urticae density began to decrease at 20 days after P. persimilis inoculation. In an Acequinocyl + P. persimilis double applied plot, T. urticae density was dramatically decreased after application and then no found the T. urticae. To practical use in farmhouse, it will be possible to control by inoculation of P. persimilis only when low density of T. urticae; however, double application with spray pesticide Acequinocyl plus apply the natural enemy P. persimilis will be good when high density of T. urticae.
