Recently, fallow paddy land located in the mid-mountain area (FPL) due to a decrease in rice consumption has increased in some regions of our country. So, grasses and forage crops available for years in once sowing should be introduced in FPL. This study was conducted to develop the technique for cultivation of grasses and forage crops using animal manure in FPL The field experiments were carried out from 2007 to 2009 on FPL at Kumsan, Chungbuk province in Korea. Cattle feedlot manure (CFM) was prepared by mixing feces and urine of cattle with rice straw in cattle feedlot for 6 months. The experimental plots were consisted of four treatments; tall fescue-based mixed pasture applied with chemical fertilizer (Control), mono-tall fescue pasture (MTFP), tall fescue-based mixed pasture (TFBMP), mono-Perennial ryegrass (MPR-FCM), mono-Italian ryegrass (MIR-FCM), mono-Red clover (MRC-FCM) and mono-Reed canarygrass (MRCG-FCM) applied with FCM. The field of tall fescue-based pasture had been sown with a grasses mixture containing 'Fawn' tall fescue, 'potomac' orchardgrass, 'Reveille' Perennial ryegrass, and 'kenblue' Kentuky bluegrass, 'Kenland' Red clover. Seeding rates were 16, 6, 4, 2 and $2\;ha^{-1}$, respectively. DM yields of forages and rates of grass coverage was higher in MTFP, TFBMP and MRCG-FCM as compated with control treatment. This result means that FPL has contained with favorable conditions for growing grass, because forage productivity is more than 15 tons per ha per year in fallow paddy land. In addition, the farmer can save the trouble of repeated plowing and sowing every year, due to the introduction of perennial grasses. The farmer must conduct the re-seeding and induce the improvement of management methods for the elevation of the persistence of red clover and perennial ryegrass, because both red clover and perennial ryegrass having high nutritive value and palatability was less persistent. Therefore, we suggest that FPL may be the good land for forage production utilizing FCM and FCM can be applied on FPL without any negative effects on DM production and the property of soil. FPL of Korea can be better utilized by applying FCM to the mono and/or mixed swards.

This study was conducted to develop the technique for cultivation of forage crops using swine slurry in fallow paddy land located in the mid-mountain area (FPL). The field experiments were carried out from 2007 to 2009 on FPL at Kumsan, Chungbuk province in Korea. Swine slurry was prepared which decayed for 6 months. The experimental plots were consisted of seven treatments; tall fescue-based mixed pasture applied with chemical fertilizer (Control), mono-tall fescue pasture (MTF), tall fescue-based mixed pasture (TFBM), mono-Perennial ryegrass (MPR), mono-Italian ryegrass (MIR), mono-Red clover (MRC and mono), Reed canarygrass (MRCG) applied with swine slurry. The field of tall fescue-based pasture had been sown with a grasses mixture containing 'Fawn' tall fescue, 'potomac' orchardgrass, 'Reveille' Perennial ryegrass, and 'kenblue' Kentuky bluegrass, 'Kenland' Red clover. Seeding rates were 16, 6, 4, 2 and 2 (kg) per ha, respectively. DM yields of forages and rates of grass coverage were higher in MTF, TFBM and MRCG as compared with control treatment. This result means that FPL has contained with favorable conditions for growing grass, because forage productivity is more than 14.5 tons per ha per year in fallow paddy land. In addition, the farmer can save the trouble of repeated plowing and sowing every year, with the introduction of perennial grasses. The farmer must conduct the re-seeding and induce the improvement of management methods for the elevation of the persistence of red clover and perennial ryegrass, because both red clover and perennial ryegrass having high nutritive value and palatability was less persistent. Therefore, we suggest that FPL may be the good land for forage production utilizing swine slurry and swine slurry can be applied on FPL without any negative effects on DM production and the property of soil. FPL of Korea can be better utilized by applying swine slurry to the mono and/or mixed swards.

Objectives: The present study aimed to provide the fundamental data for guiding establishment of measures among the rural elderly population with physical disabilities. The specific goals of this report are to reveal the prevalence of their disabilities, its tendency according to their increasing age, and to assess the background explanations. Methods: The self-administered questionnaires have been performed 432 persons of rural residents age 40 and greater in Kumsan-Gun and Chongyang-Gun, Chungchongnamdo Province. The questionnaire items included presence or not. of disabilities. specific causes for disabilities, anthropometric measures, and amount of physical activities. Results: The proportion of disabilities was higher in women than men, and the functional degree of their limbs decreased with the increasing age. The proportion of disabling extremities was higher in the lower extremities than in the upper ones. Joint diseases were the most prevalent causes for disabilities of extremities. Concerning the degree of depression, 41.2% of study subjects were normal, 47.5% had mild depression, 6.3% moderate, and 5.1% severe depression, with no statistical difference based on age and sex. The worse are the functional degree of both extremities, the greater the degree of depression the subjects had. The odds ratio for presence of disabilities of extremities was 2.6 times higher in women than in men for sex and for age, 50's were 3.5 times, 60's 4.3 times, 70's 4.9 times than 40's, respectively, with increasing tendency with increasing age. The odds ratio for depression was 1.2 times greater in subjects with disabilities than in normal population with no statistical difference. Conclusions: More efforts are needed to establish elderly specific measures for providing proper public health services centering on maintenance of physical functioning among elderly population.

Objectives: This survey was intended to provide basic data which can be available as a baseline in the set up of dietary guidelines for assuring community-based self-support of the rural elderly, through investigation of the relationship of the various dietary consumptions with their ADL and IADL. Methods: The study subjects, 439 rural residents(male: 196, female:243) aged over 65 in Kumsan Kun and Chongyang Kun, Chungchongnamdo Province were interviewed, in June of 2004, about their sociodemographic characteristics, daily life styles, the variety of dietary consumption, ADL and IADL with the following major findings: Results: In terms of the scores' distribution to show variety of food consumption among all subjects, 68.3% got 1~3 points, 23.2% 4~6 points, and 8.4% 7~10 points with a decreasing proportion of subjects in higher points. In terms of their functional status, normal-range groups showed 93.2% of ADL and 72.9% of IADL whereas, impaired ADL group 6.8% of ADL and 27.1% of IADL, respectively. Concerning the relation of ADL and IADL with the variety of their consumed food, the greater scores for food variety was associated with the significantly higher proportion of normal ADL group and the lower proportion of impaired ADL group. Multiple logistic regression analysis with ADL and IADL as dependent variables, and food variety scores as explanatory variables, the relative risk of impaired-ADL group was 0.84 in the food variety group of 4~6 points, 0.63 in 7~10 points with no statistical significance. The relative risk of impaired- IADL group was 0.52(p<0.01) in the food variety group of 4~6 points, 0.41(p<0.05) in 7~10 points with statistical significance. Conclusions: These study results suggest that the lower dietary variety, the lower functional capacity of daily living, and the variety of dietary is associated with the functional capacity of daily living in rural elderly.
