  • A high prevalence of farmer's work-related musculoskeletal disorders(MSDs) have been reported in precedent studies. To offer the basic data for reducing the melon farmer's MSDs, a questionnaire survey about MSDs symptoms and work loaded body part and video analysis by 3 checklist(REBA, RULA, OWAS) for musculoskeletal risk assessment were carried. 94 melon farmers for this questionnaire and 1 typical farm for risk assessment were participated. A total of 80.9% of the farmers reported musculoskeletal symptoms and 60.6% reported musculoskeletal symptoms over NIOSH standard. The mainly symptom body part is low back, knee and shoulders. Main risk factors in melon farm are awkward postures, heavey/frequent lifting and repetitive hand/arm motions. The high risk tasks induced by video analysis were harvesting, removing the sprouts and covering with rags. These result can be used practically for planning intervention strategy and programs to prevent farmer's MSDs.

  • In 2007 to 2008, a fruit rot of Melon (Cucumis melo L.) caused by Sclerotium rolfsii occurred sporadically in a farmer's vinyl house in Jinju City. The symptoms started with watersoaking lesion and progressed into the rotting of the surface of fruit. White mycelial mats appeared on the lesion at the surface of the fruit and a number of sclerotia formed on the fruit near the soil line. The sclerotia were globoid in shape, 1${\sim}$3 mm in size, and white to brown in color. The hyphal width was measured 3 to 8 ${\mn}$. The optimum temperature for mycelial growth and sclerotia formation was 30 on PDA. Typical clamp connections were observed in hyphae of grown for 4 days on PDA. On the basis of symptoms, mycological characteristics and pathogenicity to the host plant, this fungus was identified as Sclerotium rolfsii Saccardo. This is the first report of the fruit rot of Melon caused by S. rolfsii in Korea.

  • This study was to research the characteristics of the body shape of Korean woman farmers by the major crops. Four hundred ninety-five Korean woman farmers from 9 different area such as Kumi, Damyang, Iksan, Injae, Chungju, Choongju, Haman, Whasung, and Whasoon volunteered for this study. Their major crops were the rice, the pepper, the water melon, the strawberry, the wild rocambole, the sweet persimmon, the grapes, the mushroom, and the chrysanthemums. Twelve body angles were measured from archived the somatotype photographs of the front, the side, and the back. Questionnaires of SF-36 and the farmer's symptom, and the farm-work related movements were surveyed. The results were as follows; 1. Farmers had lower health levels in physical role limit, pain, vitality, and physical function than other occupational workers. 2. Most farmers acted the high-risk ergonomics motions when they worked in the farm. 3. There were significantly different on the both shoulder angles, the hip tangential line slope, the hip breadth angel, in frontal ankle-knee angle, the bending back angle, the dropping breast slope, the abdominis media angle, under the abdominis media angle, the glutea angle, under the glutea angle, and the sideward knee angle(p<.05). 4. Farmers cultivating the low plants such as the water melon, the strawberry, and the wild rocambole showed more banded vertebralis and side knee angles. Farmers cultivating the red pepper showed the dropping the left shoulder and O shape legs. Farmers cultivating the fruit trees such as the sweet persimmon and the grapes showed the less banded side knee angles than other farmer groups. 5. On comparing the same age, farmers showed the older's body shape in earlier and much more than the old living in the city.

  • =Objectives: This study was conducted to evaluate the diferences in Farmer's syndrome between greenhouse-melon farmers and rice farmers. Methods: The study included 160 residents, who lived in rural community. Of those subjects, 73 and 87 from June 1 to July 30, 2006. Respondents were interviewed by means of a structured questionnaire. Results: This study showed that greenhouse-melon farmers had a lower average age, shorter experience of farming, more working hours per day than rice farmers (p<0.05). n farmers was 38.4% respectively, the prevalence in rice farmers was 22.6%. There was statistically significant diference in the prevalence of Farmer's syndrome between greenhouse-melon and rice farmers (p<0.05). The most frequent symptoms among eight symptoms that constitute the Farmer's syndrome were lumbago, shoulder pain and nocturnal urination regardless of type of farming. But greenhouse-melon farmers had higher prevalence of muskuloskeletal symptoms, such as lumbago and shoulder pain, than rice farmers (p<0.05).Conclusions: These results showed that prevalence of Farmer's syndrome was more common in the tools which reduce physical burden and take a rest and exercise periodically during work in the greenhouse-melon farmers.

  • This study was to get basic data for the establishment of proper labor counterplan so that we estimated farm work volume and work loads by crops. We examined the method of work practices such as a work posture, work time, measured work environment such as hot, cold, humidity and ultraviolet rays and calculated physical loads induced by them. Also we surveyed work environment, work posture, sleeping time and work time because they affect on farmer's health. Farmer's health survey was investigated by questionnaire and measured farmer's physical load. The types of farm work were classified into greenhouse farming, rice farming, dry field farming, stock farming and special crop farming. 11 crops were selected, for example, greenhouse melon, riceㆍred pepper, milky cow farming, pear, grapes, dropwort, sweet potato, potato, radish, and cabbage. We also chose subject districts haying the most yield of 11 crops. Our survey was conducted for the period when farmers think the hardest period in physical work load. The farm work models based on work standard were presented according with farmer's health.

  • This experiment was aimed to find out the measures or soil managements in continuous melon cultivation and to produce the high quality of yellow melon in plastic film house culture. The experiment was designed with surveying of farmer's field and conducted for 4 years. The most effective measure of soil managements was to cultivate paddy rice in June after harvesting the melon and next ways were treated with submergence or the plastic film for 40days during the period of high temperature of summer and plowed over 50cm depth with plough machine. To decrease the soil problems in continous cultivation, the addition of red earth soil of 500M/T per 10a with increasing the application rates of rice straw and fertilizer (N, P, K) in 30% and 10% respectively was effective in plastic film house culture. The effect of soil amendment application was continued for two years at least and it increased the commercial quality and sugar content in brix of yellow melon in 10% and 2.6 degree respectively.

  • Oriental melon (Cucumis melo L.) is generally cultivated on the ground by creeping culture. A farmer has a higher workload for training stems. This study was conducted to find out a new cultivation of oriental melon to reduce a workload and improve the quality of fruit. There were three treatments for training stem of oriental melon; upward stem growing, downward stem growing, control (creeping stem growing). The results of the plant growth and the net photosynthesis showed higher in upward stem growing. The root activity was higher in downward stem attract. The yield was not significant as 4,055kg/10a in upward stem attract and 3,983kg/10a in downward stem attract. According to the results of the ergonomic agricultural workload evaluation, in the case of the working posture, the working posture of creeping cultivation methods (squatting, bending) showed a higher risk level than the upward and downward cultivation methods. Therefore, it is recommended the upward stem attract of oriental melon is a new cultivation as well as an alternative method for creeping stem attract in terms of improving the plant growth and yield, and reducing the workload.

  • A Linear Approximated Inverse Almost Ideal Demand System, suggested by Eales and Unnevehr, is estimated with monthly data set of Korean fruits consumption. LA/IAIDS consists of 6 demand equations which correspond to domestically produced Hanrabong, overwintering mandarin, strawberry, melon and tomato with imported orange. The results indicate that price and scale flexibilities are negative, as expected. And the significance is that a 10% increase in imported orange quantity is associated with 5.5% declines in the price of Korean Hanrabong while the price of other fruits is minimally affected. In addition, the estimate of scale flexibility of Hanrabong (-2.96) is much smaller than any other fruit. Hanrabong farmer might be in the face of deficit operation as a consequence of the substitution effect if orange would be imported in accordance with the Korea-U.S. free trade agreement.

  • The effectiveness of plant-based attractants was studied using large traps, which attracted relatively more snails in agricultural water drainage ditches and rice-cultivating environments, although their effectiveness in rice fields and lakes was limited. The rate began to rise after three hours of observation. Watermelon peel exhibited the highest apple snail attraction rate (13.8%), followed by potatoes (10.0%), and apple peel (8.8%). These values significantly differed from the attraction rate attributed to papaya leaves (F=3.84; P=0.0387). After 24 h, watermelon peel and apple peel indicated a higher rate of attraction (23.4% and 21.7%, respectively), which were significantly different compared with those of papaya leaves and potatoes (F=9.94; P=0.00455). Large bait traps outperformed funnel traps in capturing golden apple snails and trapped a significant number of snails measuring over 1 cm in size. Watermelon peel was the most effective attractant for a large bait trap, followed by apple peel, potatoes, and papaya leaves. On average, 110 snails were captured in the lure net. However, potatoes, apple peels, and papaya leaves caught an average of 93, 80, and 79 snails, respectively. Among the attractants, the lure effect of the snails was not significantly different. The efficiency of large bait traps in capturing snails, regardless of the plant attractant employed, followed the order: apple peel > watermelon peel and potatoes > papaya leaves > melon > Korean melon. Watermelon peel is highly recommended for farmer use, as well as apple peel and potatoes. Utilizing these snail attractants may contribute positively to developing a safe and environment-friendly integrated pest management strategy.

  • In Korea, rice cultivars have been changing to 'quality' rice rather than high yielding cultivars. However, more than 10% of paddy field has been changed to greenhouse in winter season for cropping of water-melon, oriental-melon, straw berry and et cetra. This experiment has been made to identify the usefulness of critical N and Si fertilization(SF) level to obtain high grain quality rice with reduced insect pest damage by N and SF combination. Before the experiment, watermelon-rice cropping system was maintained for three seasons by farmer from 1998 to 2001. The experiment of N and Si (silicate) fertilization levels was evaluated with Hwayoung-byeo (Oryza sativa L., medium-maturing variety) in 2002 and 2003 in Uiryeong, Korea. Nitrogen fertilization (NF) levels were three and five in 2002 and 2003, respectively, and three SF levels were compared for getting the valuable N/SF level in both years. TOYO-value was positively affected by Si application in N100% plot but it was negatively related with NF level. Normal grain percentage was positively related with TOYO-value and it was highest in 0N plot and Si plots in N100%. Other appearance qualities like powdered, damaged, and cracked grain, were decreased with increasing N fertilization level. SF improved appearance quality in N100% plots but no effects in other treatments. Leaf sheath related diseases were significantly decreased by SF but it was negatively related with NF. In conclusion, SF could be improve grain quality at the same yield levels of conventional fertilization and it also could be reduce the diseases damages of rice plant in all N treatments. NF treatment reduced grain quality and improved grain yield at N50% level, however NF above N50% could not get any kind of benefits. So, compared with conventional fertilizer, reduced NF level is recommended for high grain quality with reduced insect pest damage.
