    In major field crops, synthetic herbicides have been used to control weeds worldwide. Globally, herbicide resistance in weeds should be minimized because it is a major limiting factor for food security. Cross resistance can occur with herbicides within the same or in different herbicide families and with the same or different sites of action. Multiple resistance refers to evolved mechanisms of resistance to more than one herbicide (e.g., resistance to both ALS-inhibitors and ACCase-inhibitors) and this resistance was brought about by separate selection processes. Target site resistance could occur from changes at the biochemical site of action of one herbicide. Non target site resistance occurs through mechanisms which reduce the number of herbicide molecules that reach the herbicide target site. There are currently 480 unique cases (species ${\times}$ site of action) of herbicide resistance globally in 252 plant species (145 dicots and 105 monocots). To date, resistance in weeds has been reported to 161 different herbicides, involving 23 of the 26 known herbicide sites of action. Finally, it can be concluded that we can protect crops associated to herbicide resistant weeds by applications of biochemical, genetic and crop control strategies.

    An experiment was conducted to detect aquaculture pond bottom soil nutrients, pH and electrical conductivity with a view to optimize production and to incorporate the scientific method of fish nursing, rearing and culturing at Noakhali district in Bangladesh. The soil samples were collected from the recently dug ponds (1 - 5 years) and older ponds (> 5 years). Samples were taken from five different spots in a Z shape from each pond and were mixed to get a composite sample. The composite samples from the ponds were collected in polyethylene bags and shipped to the laboratory for analysis. The soil samples were analyzed with respect to pH, electrical conductivity (EC), organic carbon (OC), organic matter (OM), nitrogen (N), phosphorous (P), potassium (K) and sulfur (S). The average value of pH, OC, OM, N, P, K and S were $7.43{\pm}0.40$, $2.21{\pm}1.43%$, $1.47{\pm}0.53%$, $2.52{\pm}0.94{\mu}g\;g^{-1}$, $0.126{\pm}0.047{\mu}g\;g^{-1}$, $3.84{\pm}1.77{\mu}g\;g^{-1}$, $0.191{\pm}0.106{\mu}g\;g^{-1}$ and $306.72{\pm}222.05{\mu}g\;g^{-1}$ respectively, in Noakhali. The average EC, OC, OM, N and P contents were found to be higher in Subornachar than those in Sonapur. On the other hand pH, K and S were found to be higher in Sonapur than the values of Subornachar. The pH, EC, OC, OM, N and S contents were found to be higher in new ponds than old ponds whereas P and K contents were found to be higher in old pond than in new pond.

    This study was conducted to explore which pollen type could be an effective pollen source for self-incompatible 'Niitaka' pear (Pyrus pyrifolia Nakai), when different pollinizers were to be applied. The pollens of five different pears with similar flowering times were applied to bagged 'Niitaka' flowers grown in Cheonan city, Korea. Pollen types used were of different origins including Korean pears ('Wonhwang' and 'Chuhwangbae'), Japanese pears ('Chojuuro' and 'Okusankichi'), and Chinese pear ('Yali'). Results show that the amount of pollen produced by flowers of each cultivar was the largest in Korean pear 'Wonhwang' (234 g/100 flowers) and the smallest in Japanese pear 'Okusankichi' (126 g/100 flowers). A high proportion of large fruits (> 600 g), 71.4% of total production, was found in the fruits treated with 'Yali' pollen. However, these fruits showed an unfavorable external appearance. Based on individual fruit width differences, 'Chojuuro' treatment produced the smallest difference in fruit diameters (3.2 mm) and 'Yali' treatment' gave the largest (4.8 mm). Also, the difference in fruit length was the largest in 'Yali' (7.5 mm), which also produced the most uneven fruits among the pollinizers used. Meanwhile, the use of pollens of 'Wonhwang' and 'Chuhwangbae' improved productivity by increasing the fruit shape index and the ratio of bigger fruits in total production. Moreover, those pollens also decreased the development of lenticels on fruit skins which gave them a smoother appearance.

    This study was performed to produce succinic acid from biomass by developing mutants of Cellulomonas flavigena in which the succinate dehydrogenase gene (sdh) is deleted. For development of succinate producing mutants, the upstream and downstream regions of sdh gene from C. flavigena and antibiotic resistance gene (neo, bla) were inserted into pKC1139, and the recombinant plasmids were transformed into Escherichia coli ET12567/pUZ8002 which is a donor strain for conjugation. C. flavigena was conjugated with the transformed E. coli ET12567/pUZ8002 to induce the deletion of sdh in chromosome of this bacteria by double-crossover recombination. Two mutants (C. flavigena H-1 and H-2), in which sdh gene was deleted in the chromosome, were constructed and confirmed by PCR. To estimate the production of succinic acid by the two mutants when the culture broth was fermented with biomass such as CMC, xylan, locust gum, and rapeseed straw; the culture broth was analyzed by HPLC analysis. The succinic acid in the culture broth was not detected as a fermentation products of all biomass. One of the reasons for this may be the conversion of succinic acid to fumaric acid by sdh genes (Cfla_1014 - Cfla_1017 or Cfla_1916 - Cfla_1918) which remained in the chromosomal DNA of C. flavigena H-1 and H-2. The other reason could be the conversion of succinyl-CoA to other metabolites by enzymes related to the bypass pathway of TCA cycle.

    Cultural practices for adzuki bean and the distribution of weed species in the south-west regions of Korea were surveyed to provide information on effective weed management. Approximately 27.5% of the farm households were growing adzuki bean in an area larger than 1 ha while the rest grew the crop in an area smaller than 1 ha. Of all adzuki bean growers, 17.1% seeded in early June, 8.6% in mid June, 34.3% in late June, 17.1% in early July, 20.0% in mid July, and 2.9% in late July. The average planting distance was $71.0{\times}29.5cm$. From the 40 surveys in adzuki bean fields, 35 weed species in 17 families were identified. According to the occurrence frequency, the dominant weed species were Digitaria sanguinalis, Acalypha australis, Cyperus amuricus, Echinochloa crus-galli, and Amaranthus nangostanus in decreasing order of dominance. However, based on dry weight, Chenopodium album (34.4%) was the most dominant followed by Acalypha australis (21.9%), Amaranthus nangostanus (19.1%), Digitaria sanguinalis (7.5%), and Portulaca oleracea (6.1%). The exotic weeds found in the field of adzuki were Ipomoea hederacea, Abutilon avicennae, and Celosia argentea. The plant heights of I. hederacea, A. avicennae, and C. argentea were 259 cm, 98 cm, and 76 cm, respectively, while the fresh weights were 850 g, 66 g, and 101 g, respectively. Integrated weed management systems utilizing mechanical, chemical, and biological control techniques need to be developed for effective weed management in adzuki bean production.

    This study was performed to evaluate the effect of organic medicinal charcoal as a feed additive on aflatoxin absorption, odor emission, fecal microflora and in vitro digestibility in pig diet. A 10-day trial was conducted with 20 [(Yorkshire ${\times}$ Landrace) ${\times}$ Duroc] finishing pigs ($BW=81{\pm}3.3kg$) to investigate the population of Lactobacillus and E. coli in feces and fecal odor ($NH_3$, $H_2S$, total mercaptans, and Acetic acid) in vivo. The in vitro and in vivo treatments included: control (basal diet; CON); (basal diet + 0.25% Organic Medicinal Charcoal; OMC); (basal diet + 0.50% Pyroligneous Charcoal; PC); and (basal diet + 0.50% Coconut tree Charcoal; CC). The aflatoxin absorption capacity was 100, 10, and 20% in OMC, PC, and CC, respectively. The digestibility of dry matter in OMC was significantly higher than that of CON, PC, or CC in vitro (p < 0.05). The digestibility of organic matter in OMC was found to be significantly different from that of CON (p < 0.05). Fecal ammonia and $H_2S$ emissions of OMC were observed to be significantly lower than those of CON, PC, and CC (p < 0.05). Lactobacillus counts in feces of OMC and CC were significantly higher than those of CON and PC (p < 0.05). Fecal E. coli counts of OMC and CC were lower than those of CON and PC (p < 0.05). It was concluded that organic medicinal charcoal can be used as a feed additive in pig diets because it improves the digestibility of feed and fecal odor, and has positive effects on the population of microorganism in feces.

    This study was conducted to investigate the influence of bone boiling duration on bovine bone extract supplement quality in terms of growth performance, leg bone length, and blood profile in broilers. A total of twenty ROSS 308 broilers (initial BW of $970{\pm}50g$) were randomly divided into the following 4 treatment groups: CON (basal water), T1 (1 : 1 ratio water to bone extract boiled for six hours), T2 (1 : 1 ratio water to bone extract boiled for 12 hours), and T3 (1 : 1 ratio water to bone extract boiled for 24 hours). The broilers were allowed free access to the source of fluid or diets. Average daily feed intake (ADFI), average daily gain (ADG), and feed efficiency showed no significant differences among treatments during this experiment. However, broilers fed bone extract boiled for six hours showed a tendency for increased ADG to other treatments (p < 0.17). No significant differences were observed in organ weights (liver, spleen, bursa of fabricius) or blood profiles among the treatments during the experiment, but broilers fed bone extract boiled for six hours showed a tendency for decreased cholesterol, triglycerides, and HDL compared to the control diet. In the case of leg bone length, there were significant difference (p < 0.05) on tibia and femur among treatments. It was concluded that the six hour-boiled bone extract supplementation had beneficial effects on growth performance and blood profile of broilers.

    Fermented Rhus verniciflua (FRV) as feed additives act as excellent anti-diarrheal drugs as they increase the intestinal absorption rate therefore being indirectly associated with enhancing growth performance and increasing digestibility in livestock. A total of 80 weaned pigs with an average initial body weight (BW) of $6.82{\pm}1.11kg$ were used to evaluate a diet supplemented with FRV meal in a 6 week feeding trial with two dietary treatments [CON - basal diet; TRT - CON + 0.2% FRV] on growth performance, apparent total tract digestibility (ATTD), blood profiles, fecal microflora, and fecal score. Our results showed that the dietary supplementation of FRV improved (p < 0.05) average daily gain and gain : feed (G : F) ratio during days 15 - 42 and the overall experiment period and also increased the ATTD of dry matter (p < 0.05) at days 14 and 42. On the contrary, there was no effect (p > 0.05) on average daily feed intake, ATTD of nitrogen and energy, and blood profiles during the entire experiment. Moreover, dietary inclusion of FRV significantly increased fecal Lactobacillus (p < 0.05) counts and reduced the diarrhea during days 22 - 42. Thus, the results suggest that FRV can be used as a potential additive to improve growth performance and dry matter and to reduce diarrhea while having beneficial effects on fecal microflora in weanling pigs.

    A total of 120 weaning pigs [(Landrace ${\times}$ Yorkshire) ${\times}$ Duroc] with an average body weight of $8.95{\pm}0.88kg$ were used in this study to investigate the influence of supplementation of combined flavor and sweetener. The diets included: 1) TRT1, basal diet, 2) TRT2, TRT1 + 500 mg/kg flavor, 3) TRT3, TRT1 + 150 mg/kg sweetener, and 4) TRT4, TRT1 + 500 mg/kg flavor + 150 mg/kg sweetener. The TRT4 treatment produced a higher average daily gain (ADG) than that in the other treatments on d 0 - 14 and the whole experimental period (p < 0.05). The TRT1 and TRT2 treatments gave a lower average daily feed intake (ADFI) than that of TRT4 on d 0 - 14 and d 0 - 42 (p < 0.05). On d 15 - 42, TRT4 had a higher ADFI than that of TRT1 (p < 0.05). Compared to TRT1, dry matter (DM), gross energy (GE), and nitrogen (N) digestibility increased in pigs fed the TRT4 diet (p < 0.05) on d 14. Serum norepinephrine concentration in TRT1 treatment was higher (p < 0.05) than that in TRT4 treatment at 72 h after weaning. On d 0 - 7, diarrhea score decreased in TRT4 treatment compared with TRT1 and TRT2 treatments. In conclusion, flavor and sweetener complex addition improved ADG and ADFI as well as DM, N, and GE digestibility in weanling pigs. This supplementation in pigs' diets decreased the serum norepinephrine concentration at 72 h after weaning and the diarrhea score during the first week of weaning.

    In Korea, chemical analysis of animal feed is done through authorized feed analysis laboratories (AFALs). Analysis results among the AFALs need to be similar or within acceptable variations; however, there is no experimental evidence of their comparability. We aimed to determine the level of variation of feed chemical analysis results from different AFALs. For this, we requested analysis of four kinds of feed (corn, soybean meal, corn gluten feed, and ryegrass) to eight AFALs and the Cumberland Valley Analytical Services (CVAS) which is an internationally well-recognized feed analysis laboratory. The AFALs spent more time on analysis than did CVAS. Fiber analysis results varied significantly among laboratories. However, moisture, CP, and ash content values showed almost no variation. At least one AFAL obtained results with significant differences from CVAS for all tested values. These differences can be explained by the followings: 1) the standard methods for feed analysis (SMFA) established for AFALs are not detailed enough to control the analytical variations among different laboratories and 2) guidelines are insufficient for the quality control of analysis results in Korea. Failure to accurately identify the nutritional components of the feed could mean failure to provide adequate nutrients to the animals. Therefore, efforts to reduce the differences among AFALs, such as revising SMFA and publishing guidelines on quality control of feed analysis results, are important.

    Ramie (Boehmeria nivea) is a perennial herbaceous plant belonging to the family Urticaceae. It was used in folk remedies for diuretic or anti-pyretic purposes and as an hepatoprotective, anti-oxidant, and anti-inflammation agent. In this study, we investigated the composition of free sugars, amino acids, fatty acids, organic acids, and total polyphenol contents in parts of ramie (root, stem, and leaf) and different harvest areas (10 areas). Overall, free sugars were found as sucrose, glucose, fructose, and galactose at concentrations ranging from 24.5 to 1173.8 mg/g. Amino acids lysine, threonine, tyrosine, phenylalanine, and histidine were detected at concentrations of 33.8 to 3735.3 mg/g. Major fatty acids were linoleic acid, palmitic acid, and linolenic acid at concentrations of 7.3 to 364.4 mg/g. In organic acids, the concentration of malic acid was highest of all with 672.2 mg/g. The content of free sugars, amino acids, fatty acids, organic acids, and total polyphenol was higher in leaves than in roots and stems. In contrast, the total polyphenol content was higher in roots with 33.7 - 219.4 mg/g than in leaves or in stems. As seen in collecting region, the contents of free sugars, amino acids, fatty acids, organic acids, and total polyphenol of Bn-33, 39, 55, 65, and 90 were higher than other samples. Chemical compositions of different parts of ramie are important factors to consider in manufacturing functional foods. The results of this study provide fundamental information on the chemical compositions of ramie parts and would help develop new functional foods from ramie leaves or the whole plant.

    Anthocyanins contained in Rhododendron schlippenbachii (royal azalea) are expressed in a variety of colors and affect flower colors. R. schlippenbachii flowers of seven colors (white, red group: pink, deep pink, red, purple group: light purple, purple, deep purple) were collected from the garden around KT&G building in the college of agriculture and life science. Seven types of anthocyanins [cyanidin 3-O-diglucoside, cyanidin 3-O-arabinoside-5-O-glucoside, cyanidin 3-O-galactoside, peonidin 3-O-arabinoside-5-O-glucoside, cyanidin 3-O-glucoside, cyanidin 3-O-(6"-O-malonyl) arabinoside, cyanidin 3-O-(6"-O-coumaroyl) glucoside] turned out to be from the cyanidin and peonidin series in R. schlippenbachii flowers. Also, seven types of flavonols [azaleatin 3-O-glucoside, azaleatin 3-O-arabinoside, azaleatin 3-O-rhamnoside, quercetin 3-O-galacatoside, quercetin 3-O-glucoside, quercetin 3-O-arabinoside, quercetin 3-O-rhamnoside] were identified in R. schlippenbachii flowers. Total anthocyanin amounts decreased in R. schlippenbachii flowers in the following order: 'deep pink' (8.07) > 'red' (6.37) > 'pink' (5.35) > 'deep purple' (0.78) > 'purple' (0.43) > 'light purple' ($0.22mg{\cdot}g^{-1}$ dry weight, DW) > 'white' (not detected). Total flavonol amounts decreased in the following order: 'pink' (97.78) > 'deep pink' (63.79) > 'deep purple' (61.98) > 'white' (57.58) > 'light purple' (47.06) > 'purple' (46.76) > 'red' ($7.60mg{\cdot}g^{-1}$ dry weight, DW). This study provided the quantitative and qualitative information for the variation of anthocyanin and flavonol compounds in R. schlippenbachii flowers. Furthermore, this information can contribute to the identification of anthocyanin and flavonol compounds in other Rhododendron flowers.

    An experimental pick-up type pulse crop harvester was built and its harvesting performance for green kernel black bean was evaluated. Field bean loss and harvested bean quality of the harvester were analyzed according to engine speeds of 2,000; 2,400; 2,800; 3,000; and 3,200 rpm, and travel speeds of 0.6; 1.0; and 1.4 m/s. Operating conditions and field capacity of the harvester for proper harvesting were estimated. The harvester had an optimum performance at a grain moisture content of 13.4%, an engine speed of 3,000 rpm, and a travel speed of 1.2 - 1.3 m/s. Subsequently, the picking-up, discharging, and total bean loss ratios were found to be 1.6, 1.3, and 2.9%, respectively. The whole bean, damaged bean, unthreshed bean, and foreign material ratios were determined to be 96.2, 1.0, 0.1, and 0.3%, respectively. Results showed that the harvester had lower bean loss and higher harvested bean quality than those of imported bean combines. The harvester could harvest 2 rows with a crop spacing of an approximately 1.4 m. Its optimum travel speed was estimated to be approximately 1.2 m/s when harvesting performance was taken into account using such variables as field bean loss and harvested bean quality for green kernel black bean. Effective field capacity of the harvester was estimated at approximately 40 a/h.

    Nowadays, many people suffer from stress because of their jobs, studies, traffic, etc. Daily stress may cause many diseases (Garrett, 1991). One of the methods for reducing stress is experiencing a natural environment (Frumkin, 2001). Cibodas botanical garden (CBG) is one of the most famous travel destinations in Bogor, Indonesia. CBG has the potential for tourism activities. However, an economic assessment is required to verify their sustainability. The research objectives of this study were to identify the characteristics of tourism utilization in CBG, to analyze the economic tourism value of CBG, and to measure the effectiveness of traveling to a natural environment for reducing stress. The research method used was the survey. This study used three data analysis methods: (1) descriptive analysis which was used to identify the characteristics of tourists, (2) travel cost method (TCM), and (3) contingent valuation method (CVM). Results showed some differences in the characteristics of foreign and domestic tourists respondents in age, educational background, income level, number of dependents, and the frequency of their visits. CBG has a high economic value, amounting to IDR (Indonesian Rupiah) 5,508,932,605,405 or approximately USD (United State Dollar) 413,000,000. WTP (Willingness to Pay) of domestic tourist respondents was IDR 29,702 or USD 2.2 per visit, while the value of foreign tourist respondents reached IDR 39,700 or USD 2.9 per visit. Respondents found it preferable to pay more for tickets (WTP value) than to buy medication to reduce their stress.

    The purpose of this study was to investigate the status of agricultural management accounting information, education status, and policy demands through a questionnaire survey of advanced agricultural managers. These people are expected to play a key role in the changing agricultural environment in Korea. Based on survey results, several policy implications were derived for the advanced agricultural managers' agricultural management accounting information record activation. Survey results of 303 respondents identified that 63.4% of them record their agricultural management accounting information. The biggest reason given for not recording this information was lack of time for record keeping. The biggest problem was a 'lack of Question and Answer system'. In addition, 37.2% of the respondents were not aware of the current agricultural accounting guidelines. In terms of education, 71.3% of the respondents have completed course work in accounting and responded that an 'On-off parallel education system', which offers both online and offline classes, was the most effective method to prevent dropout. Respondents thought that agricultural management accounting records were helpful for the management of agriculture and their participation in government policies. They also thought that customized education programs should be further implemented for enhancing the effectiveness of education programs, and 'One-stop Question and Answer system on related web sites and organizations' is required for them to keep better records. The following policy implications can be derived from the survey results. First, interoperability between agricultural management accounting information recording programs is needed. Second, accessibility should be strengthened. Third, the education system needs to be improved. Fourth, voluntary participation should be encouraged. Last, the government needs to establish a post-verification system.
