The nematicidal, antifungal and antioxidant activities of methanol extracts from six Vietnamese native medicinal plants were evaluated by various assays in vitro. Of the plant extracts tested, Terminalia nigrovenulosa was found to possess the highest activity when compared to the others. The leaves and bark of T. nigrovenulosa showed strong inhibitory activity against Meloidogyne incognita and Fusarium solani. The DPPH (1,1-Diphenyl-2-picryl-hydrazyl) radical scavenging, reducing power and total antioxidant activities of T. nigrovenulosa bark were higher than that of the remainder plant extracts. Chitinase activity of these plants was also investigated using SDS-PAGE. The results obtained in the present study indicate that T. nigrovenulosa leaf extracts are the greatest potential source as nematicides and fungicides for the control of M. incognita and F. solani. In particularly, T. nigrovenulosa bark extracts could be used as a potential source of commercially viable levels of natural antioxidant.

This study was carried out to investigate the consumption behaviors of environmentally-friendly agricultural products, including satisfaction of purchases. Questionnaires completed consumers were statistically analyzed. Regarding purchase frequencies of environmentally-friendly agricultural and animal products, consumers consumed them 1 time per month. No significant differences in consumption by age, living area, family type, or BMI were found. Exactly 38.2% of consumers preferred to purchase items in the packing amount of 0.2-0.5 kg, whereas 39.7% of consumers preferred amounts from 0.5-1.0 kg. Significant differences in packing amount were found according to age (p<0.05) and family type (p<0.01). However, there were no significant differences according to living area or BMI group. Many consumers made decisions based on the outer packing label (69.6%). Significant differences by age and living area were not found, whereas there was significant difference according to family type (p<0.05). Consumers answered that they purchased products in a general supermarket (24.7%) and cooperative (24.2%). Significant differences were found by age and living area (p<0.01) but not by family type. Consumer satisfaction of purchases scored 3.39 out of 5 points. In conclusion, significant differences in consumer satisfaction were not found according to age, living area, family type, or BMI.

The purpose of this study is to establish the management plannings for the conservation and environmentally friendly use of Korean coastal wetlands. The function, economic value, and the necessity for the conservation of coastal wetlands are described. The current management status, Korean Governmental policies for the use of coastal wetlands, and their problems are surveyed and analysed. The management plannings for the environmentally friendly use of Korean coastal wetlands is suggested as follows: (1) The coastal wetlands need to be divided into 3 different regions based on PSR(Pressure, State, Response) of OECD. (2) Each region should be managed by appropriate management plans which are suggested in Chapter IV of this paper. Finally, in order to realize these management plannings the change of Governmental system and laws are suggested as follows: (1) The change of relevant laws is required. Additionally, each region should managed by proper governmental agencies. (2) The EIA(Environmental Impact Assessment) system should be improved. (3) The participation of regional people should be guaranteed in the decision making processes of the business and other important planning regarding coastal wetlands.

The paper analyzed on the level of consumer member's awareness to green marketing strategies (4P's; product, price, place and promotion strategies) of Hansalim specialty shops for environmentally friendly agri-products. For the study, Hansalim-Cheonanasan members had been surveyed. Consumers purchase environmentally friendly agri-products because quality and freshness of those is good. The difference in amount of the average monthly purchase between loyal customers and disloyal customers is about 130,000 won. And customer's awareness is that the first is promotion strategy, the second product strategy, the third place strategy, the last price strategy. The average monthly purchase is related with product strategy in correlations between the 4P's each other. If Hansalim maintains a product strategy, promotes extensively and keeps their product standard, more consumers will purchase Hansalim products because the most important one of effect of green marketing strategies on consumer behavior is products. Hansalim needs to go into action to increase recognition. Some of consumers have misconcepts or don't know about the 4P's well. If Hansalim promotes positively considering interrelationship about 4P's strategies or other strategies, the consumers awareness will be changed more effectively. This study shows that balanced 4P's is better than only one superior strategy because of the correlation amomg green marketing strategies.

The aim of the present study was to develop a sensitive and specific detection method for the rapid detection of apple scar skin viroid (ASSVd) in apple leaves. The resulting reverse transcription recombinase polymerase amplification (RT-RPA) assay can be completed in 10 min at 42℃, is 10 times more sensitive than conventional reverse transcription polymerase chain reaction, and can specifically amplify ASSVd without any cross-reactivity with other common apple viruses, including apple stem grooving virus, apple stem pitting virus, and apple chlorotic leaf spot virus. The reliability of the RT-RPA assay was assessed, and the findings suggested that it can be successfully utilized to detect ASSVd in field-collected samples. The RT-RPA assay developed in the present study provides a potentially valuable means for improving the detection of ASSVd in viroid-free certification programs, especially in resource-limited conditions.
