  • Non-timber forest products are important component of subsistence and livelihood of tribal communities living in and near forests. This is of particular significance in the state of Arunachal Pradesh having more than 80% of geographical area under forest cover and predominantly inhabited by tribal people. Purpose of this study was to document the status and utilization pattern and to assess the economic value of NTFPs of the state. Present study was carried out in eight districts of Arunachal Pradesh viz., Changlang, East Kameng, Lower Subansiri, Tawang, Tirap, Upper Siang, West Kameng and West Siang covering 34 villages and 350 households. Altogether, 135 plant based and 36 animal based non-timber forest products were recorded. Among plant based NTFPs, 54 species were collected for leaves, 30 for stem and 22 for fruits. Most of the animal based NTFPs (93%) were collected/hunted for food. Average 20~40 kg of NTFPs was collected annually per household. Maximum plant based NTFP collection was recorded from West Siang followed by West Kameng and Tawang. Similarly, highest collection of animal based NTFPs was recorded from West Siang followed by Tirap and Lower Subansiri. NTFP contributed more than 50% of annual income of the people of East Kameng, Tirap, Lower Subansiri and Upper Siang districts. An illiterate and unemployed person with minimum agricultural land was more dependent on forests for his livelihood than a literate jobholder. The study concludes that a large section of people of Arunachal Pradesh are dependent on NTFPs for their livelihood however due to its unscientific harvesting, the availability of NTFPs is receding with time. There is an urgent need to promote cultivation and scientific harvesting of NTFPs in order to conserve the plant and animal diversity of this global biodiversity hotspot and for ensuring livelihood security of the people living in this area.

  • BACKGROUND: Bisphenol A (BPA) is a chemical widely used in polycarbonate plastics, epoxy resins. BPA is an endocrine disruptor. Residue of BPA in agricultural environments is a major concern. The objective of this study was to understand the characteristics of the uptake and distribution of BPA and its metabolites introduced into the agricultural environment to crops, and to use it as basic data for further research on reduction of BPA in agricultural products. METHODS AND RESULTS: This study established the analysis method of BPA and its metabolites in soil and crops, and estimated the intake of BPA and its metabolites from lettuce (Lactuca sativa) grown in sandy loam and loam soil, which are representative soils in Korea. The two major metabolites of BPA were 4-hydroxyacetophenone (4-HAP) and 4-hydroxybenzoic acid (4-HBA). BPA, 4-HAP and 4-HBA have been analyzed by using liquid chromatography tandem mass spectrometry (LC-MS/MS). These substances were detected in sandy loam and loam soil, indicating that certain portions of BPA were converted to 4-HAP and 4-HBA in the soil; however, it was observed that only 4-HBA migrated to lettuce through the roots into crops. CONCLUSION: The uptake residues showed the BPA and 4-HAP were not detected in lettuces grown on sandy loam (SL) and loam (L) soil treatments that were applied with of 10 ng/g, 50 ng/kg and 500 ng/g of BPA. However, the 4-HBA was detected at the level of 7 ng/g and 11 ng/g in the lettuce grown in sandy loam and loam soil that were treated with the 500 ng/g of BPA, respectively, while the 8 ng/g of 4-HBA was measured in the lettuce cultivated in the loam that was treated with 100 ng/g of BPA. This result presents that the BPA persisting in the soil of the pot was absorbed through the lettuce roots and then distributed in the lettuce leaves at the converted form of 4-HBA, what is the oxidative metabolite of BPA.

  • The purposes of this study were 1) to classify adult consumers according to their desired clothing benefits on natural-dyed clothes, 2) to identify the differences of life-style among the classified groups, and 3) to determine the interest in Korean traditional culture, interest in dyeing, and demographics among the groups. The survey subjects were 283 adults. The data were analyzed utilizing factor analysis, cluster analysis, $x^2$-test, one-way ANOVA, Duncan test and multiple regression analysis. Based on the 6 dimensions of clothing benefits that were identified by factor analysis, adult consumers were classified into three clusters: eco-friendly oriented group showing the highest scores in environment conservation and comfort in clothing benefits, individuality-oriented group showing the highest scores in individuality and quality, and indifference group showing lower scores in all of the desired clothing benefits. The eco-friendly group showed the highest scores in attitude toward Korean traditional culture, and tended to have the most interest in natural and traditional methods of dyeing. The group members appeared to have passive life-styles, be older and married, and have a higher income than the other groups. The more positive attitude they had in Korean traditional culture, the higher was the purchase intention shown in the eco-friendly group. The individuality-oriented group showed active life-styles. This group tended to be younger than the other group. The more affirmative attitude in Korean traditional culture and the greater interest in the natural dyeing, the higher was the consumers' purchase intention of natural dyeing apparels. The indifference group tended to be younger, unmarried, and have a lower income. This group was not interested in natural dyeing apparels. The study findings demonstrated that consumers with different clothing benefits sought have different buying patterns on natural dyeing apparels. Finally the marketing implications are discussed.

  • To investigate the genetic relationships among various cattle breeds, bovine mtDNA D-loop region was used in 411 animals of 18 cattle breeds, including 8 Asian Bos taurus, 7 European Bos taurus, 1 Asian Bos indicus, and 2 African Bos indicus. The size of amplified PCR products from mtDNA D-loop region was 964 bp and the products were digested by 15 different restriction enzymes. Two different band patterns were identified in eight restriction enzymes (BstXI, Hae III, Msp I, Apa I, Taq I, Alu I, BamH I, EcoN I) and the rest of restriction enzymes showed more than 3 different band patterns among which Apo I and MspR9 resulted in 7 different restriction patterns. The genotypes, number of haplotype, effective number of haplotype, and degree of heterozygosity were analyzed. Based on all the PCR-RFLP data, different haplotypes were constructed and analyzed for calculating genetic distances between these breeds using Nei's unbiased method and constructing a phylogenetic tree.

  • Objective: This study aimed to test the accuracy of self-reported information used in indirect estimation of pesticide exposure. Methods: To do so, self-reported values on the duration of pesticide application per day were compared with observed values. The number of days of pesticide application per year as recorded in self-administered logs was compared with recalled values. Results: It was found that participants underestimated the duration and frequency of actual pesticide use. High correlations were found between self-reported values and observed values, as well as between recalled values and recorded values. Conclusions: The reason might be that farmers unconsciously under-recall the application of pesticide since many customers prefer eco-friendly agricultural products. Farmers thought the task of applying pesticides to be essential, and this may explain why the participants in this study tended to accurately recall their pesticide-related work.

  • This study attempted to understand the perception and the degree of trust that consumers had in the national agricultural food accreditation system, to inquire into and examine the consumers' perception of traditional food quality certification performed for the protection of excellent traditional food, and to propose the right direction for the policies on the traditional food quality certification system and the plans to improve consumers' perception of the system. According to the results of this survey performed in married women, based on the 'the recognition of accreditation system' and 'the recognition of certification marks' of 'the seventh national agricultural food accreditation system' presently being used by the Ministry for Food, Agriculture, Forestry and Fisheries, the household food purchasers showed high recognition for eco-friendly agricultural product accreditation, processed food KS certification, and organically processed food certification in that order. Meanwhile, it was shown that they indicated low recognition for the traditional food-related accreditation systems such as 'traditional food quality certification' and 'food grand master'. It was found that reliability of the certification mark provided by the agricultural food accreditation system gained 3.54 points (on a 5-point scale), and 68.1% of the study subjects referred to the certification marks while purchasing agricultural foods. And most of them answered to the question of 'why they referred to the certification marks' saying that it was done 'to choose safe food'. The most frequent answer to question of 'the means to recognize the traditional food quality certification system' was 'broadcasting, advertising'. 57.3% of the subjects had a previous experience of buying a product certified by the traditional food quality certification system, and 93.2% of all the subjects had the intention to buy a product certified by the traditional food quality certification system later. And most of them answered that 'strengthening government policies' would be the most ideal way to inform the public of the traditional food quality certification system. According to the results of this study, while 'relying on the traditional food quality certification system in general' was relatively high among the consumers, 'intention to buy quality certified products by visiting a distantly located store' was low; thus, from this analysis, it can be seen that there is a need for diversification of places selling these quality certified products and to establish a distribution network for these products.

  • Many probiotic species have been used as a fermentation starter for manufacturing functional food materials. We have isolated Bifidobacterium animalis subsp. lactis LDTM 8102 from the feces of infants as a novel strain for fermentation. While Glycine max has been known to display various bioactivities including anti-oxidant, anti-skin aging, and anti-cancer effects, the immune-modulatory effect of Glycine max has not been reported. In the current study, we have discovered that the extract of Glycine max fermented with B. animalis subsp. lactis LDTM 8102 (GFB 8102), could exert immuno-modulatory properties. GFB 8102 treatment increased the production of immune-stimulatory cytokines in RAW264.7 macrophages without any noticeable cytotoxicity. Analysis of the molecular mechanism revealed that GFB 8102 could upregulate MAPK2K and MAPK signaling pathways including ERK, p38, and JNK. GFB 8102 also increased the proliferation rate of splenocytes isolated from mice. In an animal study, administration of GFB 8102 partially recovered cyclophosphamide-mediated reduction in thymus and spleen weight. Moreover, splenocytes from the GFB 8102-treated group exhibited increased TNF-α, IL-6, and IL-1β production. Based on these findings, GFB 8102 could be a promising functional food material for enhancing immune function.

  • BACKGROUND: The concern over heavy metal(loid)s in arable land and agricultural products increases for public health in recent years. This study aims to identify transition characteristics of heavy metal(loid)s and to assess dietary risk in barley grown at the major producing districts in Korea. METHODS AND RESULTS: The soil and barley samples were collected from 38 locations around the major producing districts at Jeollabuk-do in Korea for the propose of examining the concentrations of heavy metal(loid)s. The 34 barley samples were separately purchased on the market for the same survey. The average concentration and range of arsenic (As), cadmium (Cd) and lead (Pb) in barley grown at the major producing districts in Korea were 0.037 (0.016-0.094), 0.028 (0.004-0.083) and 0.137 (0.107-0.212) mg kg-1, respectively. Currently, the maximum allowable level for barley Pb is set at 0.2 mg kg-1 in Korea, and the monitoring results suggested that some samples exceeded the maximum allowable level and required appropriate farming management. Bio-concentration factor values by heavy metal(loid)s in barley were high at Cd, copper (Cu) and zinc (Zn), similar to other crops, while As and Pb were low, indicating low transferability. CONCLUSION: Human exposure to As, Cd and Pb through dietary intake of barley might not cause adverse health effects due to relatively low concentrations, although the Pb in some barley was detected higher than the maximum allowable level. Further study on uptake and accumulation mechanism of Pb by barley might be required to assess the human health risk associated with soil contamination.
