  • White grub damages various crops, trees and they can also be one of the most serious pests of turf grass in golf courses. This study was conducted to determine the biocontrol of white grubs with 18 different kinds (anise, camphor, castor, cinnamon, clove oil, citronella, fennel, geranium, lavender, lemongrass, linseed, neem, peppermint, pine, rosemary, tea-tree, thyme, and turpentine) of plant essential oils in laboratory, green house and field. Anise oil (88.9%), linseed oil (100%), and tea-tree oil (88.9%) were highly effective among tested essential oils against 3rd instar of Bifurcanmala aulax in cap vial experiment. However, anise and linseed oils showed low mortality against $3^{rd}$ instar of Popillia japonica in pot greenhouse experiment. Efficacy of anise, linseed oil, and tea-tree was also different depending on target white grub in field trials. Correlated mortality showed 32.6% only in tea-tree oil treatment against pupae of Adoretus tenuimaculatus however, correlated mortality of anise, linseed and tea-tree oil were 54.8, 51.6 and 56.5% respectively against $3^{rd}$ instar of Exomala orientalis in the field trial in Adelscott Country Club in Hapcheon, Gyeongnam province.

  • This study was carried out to identify the factors affecting the distribution of suitable habitats for Geranium carolinianum, which was naturalized in South Korea, and to predict the changes of distribution in the future. We collected occurrence data of G. carolinianum at 68 sites in South Korea, and applied the MaxEnt model under climate change scenarios (SSP2-4.5, and SSP5-8.5). Precipitation seasonality (bio15), mean temperature of warmest quarter (bio10), and mean temperature of driest quarter (bio09) had high contribution for potential distribution of G. carolinianum. According to climate change scenarios, high suitable habitats of G. carolinianum occupied 6.43% of the land of South Korea in historical period (1981~2010), and 92.60% under SSP2-4.5, and 98.36% undr SSP5-8.5 in far future (2071~2100).

  • All living organisms depend on soil and water for their sustained growth and development. In recent years, sustenance of life in these growth matrices has been adversely affected by the cumulative increase in environmental pollutants resulting from increasing population, growing economies and resource-use. This review provides a glimpse into the problem of global environmental pollution, the traditional technologies available for remediation and the scope of emerging‘plant-based remediation’technologies. Phytoremediation, the use of plants to effectively remove or stabilize contaminants from the growth substrate, is a low cost and ecologically friendly alternative to the common‘dig and dump’technologies. The field of phytoremediation has been driven by the intrinsic need for identification of ideal candidate plant species. To date, there are only a very few identified plants which satisfy all of the prerequisites for use in phytoremediation. The review focuses on one such plant species, the common horticultural plant scented geranium (Pelargonium sp.), with demonstrated potential to remediate metal / salt contaminated soils / aqueous systems. The characterization of tolerance and metal / salt accumulation potential of Pelargonium sp. and its efficacy in remediating complex contaminated sites are described. The unique ability of scented geraniums to tolerate excessive amounts of multi-metals, hydrocarbon and salt mixtures, and at the same time to accumulate significant amounts of metal and salt ions in the biomass, renders this plant species as one of the ideal candidates for remediation.

  • The experiments were performed to examine the effects of simulated acid rain (pH 1.0${\sim}$5.0) prepared by mixing sulfuric acid and nitric acid at the ratio of 3 : 1 on germination and growth of seedlings of some floricultural crops. Days to germination showed a one to three days' interval among crops, but pH level did not show any effect on germination for each crop. All seeds used in this experiment did not germinate at pH 1.0. At pH 2.0, the flowering cabbage and geranium still did not germinate, and even though the radicles of seeds were germinated, root hairs did not develop. The length of hypocotyls and radicles appeared to be significantly different according to the pH levels.

  • Purpose: To determine the effects of 10 % lidocaine spray and aroma hand massage on pain, anxiety, blood pressure, and pulse during arteriovenous (AV) fistula needling in hemodialysis (HD) patients. Methods: This study used a quasi-experimental design. Forty HD patients were assigned to either 10 % lidocaine spray group (n=21) or aroma massage group (n=19). 10 % lidocaine was sprayed 3 times around AV fistula 10 minutes before. Aroma hand massage was performed for 5 minutes with fluids containing 2 % of lavender, peppermint, and geranium concentrate mixture. Pain, anxiety, blood pressure, and pulse were measured during AV fistula needling without any intervention on the first week and during interventions on the second week. Data were analyzed with ${\chi}^2$ test, Fisher's exact test, t-test, paired t-test and MANCOVA. Results: Pain and anxiety were significantly decreased in both the lidocaine spray group and aroma massage group. Aroma hand massage was more effective to reduce pulse during AV fistula needling. Conclusion: The results suggest that 10% lidocaine spray and aroma hand massage may be effective to reduce pain, anxiety, and pulse during AV fistula needling in HD patients.
