The investigation of the kinds and density of white grubs in relation to soil texture, forages, years after pasture establishment, and management methods in pasture were surveyed in Livestock Experiment Station, Suwon by digging 5 sites($100cm{\times}100cm$) in a month from April to October during 1985. The results obtained were summarized as follows; No difference was observed in white grub species divesity in relation to soil texture, forages, years after pasture establishment, and management method of pasture, but the abundance of each species was different from the environmental factors.1. On the soil texture; Miridiba kureana, Popillia uchidai, Holotrichia mmosa and Holotrichia diomphalia occurred in the clay loam field, whereas Anomala corpulenta and Anomala mfocuprea in the sandy loam. 2. On the forage; the density of all species except Popillia uchidai was higher in grass than legume. 3. On the years after pasture extablishment; both of the species diversity and abundance were increased 3 years after pasture establishment and maximized at the 5th year.4. On the management methods of pasture; species diversity and abundance were higher in meadows than pastures.
This study was performed to suggest the health management of farmers compared with different farming types, such as rice plant, livestock, horticulture, orchard and others, for the farmer's health enhancement. For this study, 720 subjects were selected in 8 provinces through cluster method, and relevent caculations for the analysis of the subjects were made SAS program, and tested significance with x$^2$ and F value, those probability levels were 0.1%, 1% and 5%. Among the subjects, aged 40's were 38%, females 66%, elementary graduates (32%), and think of living conditions were average (67%). In the self-consciousness test for health, there was no significant difference of farmers with farming types. In the aspect of agricultural work situation, they took holidays according to the weather conditions or no pressed work to be done. And They took a break “when they feel tired during work”. For the recovery of fatigue, sleeping was chosen as the most favorite (68%) followed bathing (17%). but exercise was the lowest (7%). In the case of working conditions, 74% of them replied they work under average condition, and only 9% of them thought they were under pleasant surroundings. And 37% of them have had healthy food, for health practice and restorative for health. 20% of them have had breakfast irregularly. In addition to the regular meal intake, sufficient re자 and pleasant agricultural working conditions would be necessary for health, and the farmers themselves should recognize the importance and care of health. The project for enhancement of the farmers' health is needed and who should give guideline to have the responsibility for health.

The agricultural policy/Environmental eXtender (APEX) model was developed by the Blackland Research and Extension Center in Temple, Texas. APEX is a flexible and dynamic tool that is capable of simulating a wide array of management practices, cropping systems, and other land uses across a broad range of agricultural landscapes, including whole farms and small watersheds. The model can be configured for novel land management strategies, such as filter strip impacts on pollutant losses from upslope crop fields, vegetated grassed waterways in combination with filter strip impacts, and land application of manure removed from livestock feedlots or waste storage ponds. The APEX model has continually evolved since its inception, and the process of adaptation and modification will likely continue as use of the model expands for an ever-increasing range of environmental problems and conditions. Several improvements to specific model subroutines have already been initiated, while other potential improvements have been identified that will require future research and code modification efforts.
The objective of this study were to review and analyze the application technologies of electronics and microprocessor for environment control and automated management systems of livestock production of the advanced countries, and to select the appropriate and applicable technologies for our systems among the analyzed. In this study, the environment control systems were analyzed mainly on the poultry production systems; and the automated management systems on swine and dairy production systems. According to the results, the advanced technologies reviewed and analyzed could be applicable for designing our animal production systems, if those were modified and remodeled for our situation.
Background: Ethiopia is among the poorest countries where land degradation caused livelihood problem to its inhabitants. The livelihood of rural communities in Ethiopia is seriously threatened by land degradation. Land is the major natural resource that economic, social, infrastructure, and other human activities are undertaken on. Thus, land resources play an important role in shaping rural livelihoods, and lack of sustainable land management practices leads to land degradation. Thus, this study aimed to analyze interlink between land degradation and livelihood of rural communities in Chilga district, Northwest Ethiopia. It also addresses the factors which influence income diversification for livelihood of households in the study area. Result: The result depicts that the major causes of land degradation are both natural and anthropogenic. Land degradation and livelihood are negatively interlinked with each other. The livelihood of the majority of the population in the study area is dependent on subsistence agriculture both farming and animal husbandry with low diversification. The survey result showed that more than half (69%) of the sample households have farm size of less than 2 ha, nearly one third (31%) have 2.0-2.5 ha, and insignificant number of farmers have more than 2.5 ha. More than 80% of the respondents pointed out that land degradation has impacts both on crop yield and livestock production. Most of the explanatory variables such as gender, age, education level, farmland size, and family size have statistical significant influence (at P < .01 and P < .05 levels) for income diversification of households, while marital status on the other hand is not statistically significant though it has positive relation with income diversification in this study. Conclusions: Our results suggest awareness should be created in the community about the livelihood diversification mechanisms which enabled them to engage in different income-generating activities and comprehensive watershed management should be implemented.

Optimum pasture management during the summer season is an important factor to maintain good regrowth and persistence of pasture in Korea. This experiment was carried out to investigate the effects of the cutting management on the dead plant, weed appearance, regrowth and carbohydrate reserves in stubble, and dry matter yield of tall fescue dominated pasture during the mid summer season. For the test, a split plot design with 4 replications was treated with 2 different the third cutting times (July 12 and Aug. 4) as the mainplots, and 3 different cutting heights (3, 6 and 9 cm) at the third cut as the subplots, and the experiment was done at the experimental field of the Livestock Experiment Station, in Suweon, 1984. The results obtained are summarized as follows: 1. Considering the meteorological conditions during the experimental period, the temperature was a little higher by $2^{\circ}C$ than that of average year, especially the first and second decade of August were high. And the precipitation of 1984 tended to be low when compared with the average year. 2. Temperature of soil surface and underground tended to increase by $1-3^{\circ}C$ as the stubble height was low during the summer season. 3. Regrowth leaf length and leaf area after the third cut increased significantly with the high cutting height at the third cut. 4. A significant higher total nonstructural carbohydrate (TNC) content in stubble after the third cut was observed in the high stubble cut on July 12. The results indicate that the high stubble height reserves more carbohydrates for early regrowth stage after the third cut when compared with the low stubble. On Aug. 4, however, the recovery of TNC contents after the third cut was not effective due to high temperature and rainfall. 5. The percentage of dead plant after the third cut was found to be high with the low cutting height during the mid summer season (p<0.05). 6. With the low stubble height on July 12 cut, it was appeared that the percentage of weed was significantly increased (p<0.05), and main weeds appeared after the third cut were Echinochloa crusgalli>Digitaria sanguinalis>Cyperus iria>Rumex crispus, and so on. In case of cut on Aug. 4, weed appearance was no difference at three cutting heights. 7. Dry matter yield at the third cut was increased in the plot of cutting on Aug. 4 and stubble height (p<0.05). However, yields at the fourth and fifth cut were increased with high stubble height (p<0.05), regardless of harvest time. 8. In total dry matter yield after the third cut, there was no significant difference between the cutting time and forage yield. However, total yield on July 12 was increased with the high stubble height (p<0.05). 9. From the above results, it is suggested that the 9 cm cutting height during the mid summer season is the most effective for good regrowth, weed control and forage yield of tall fescue dominated pasture.

Objectives: The purpose of this study was to seek measures for improvement and management of farm work safety and health by conducting questionnaire surveys and on-site investigations to ascertain the present state of occurrence of safety accidents and safety and health management levels among swine farmers. In particular, the purpose of this study is to provide basic data for the establishment of measures for the management of safety and health suitable to the characteristics of related working environments. Methods: Questionnaire surveys were conducted among 223 farmers engaged in swine farming in 14 regions, and 10 farms were visited in order to implement multilateral methods, including in-depth interviews, along with field surveys. Results: The surveys indicated that 26.2% of all respondents experienced farm-work related safety accidents and body-reaction related accidents showed a high ratio at 31.1% of all respondents. With regard to cause materials of safety accidents, work other than that directly related to swine raising showed high ratios of safety accidents, with pigsty facility related accidents at 26.6%. Although most workers recognized the dangers latent in the working environments, their behavior and responses to the prevention of safety accidents were still insufficient due to a lack of understanding of safety and health management. In the survey on the present state of personal hygiene and wearing of protective equipment, workers were found to have been exposed to dangerous and harmful environments both inside and outside pigsties, but the actual states of their wearing protective safety equipment were very poor. Conclusion: Given the results of this study, swine farmers well recognize problems in their control of safety accidents and management of safety and health, but their knowledge about safety and health education and management guidelines was insufficient. Therefore, safety and health education, public relations, and customized personal protective equipment suitable for swine raising work should be developed in order to address the foregoing problem.
This study was conducted to investigate the effect of integrated pest management (IPM) with 3point 5score microscopic monitoring method for laying farms infected with poultry red mites. A total of 8 laying farms infected with poultry red mites were divided into two treatments: 1) integrated pest management with 3point 5score microscopic monitoring method and 2) normal pest management with 3point 5score microscopic monitoring method. The results revealed that there is no significant difference between the groups with respect to the score of poultry red mites not only regardless of disinfection for the laying farms but also from week 4 to week 20 (P>0.05). However, the farm with IPM had a lower (P<0.05) score than those with the normal pest management method on week 24. Based on the result of the present study, controlling the presence of poultry red mites using IPM, along with consistent monitoring and supplementation using the 3point 5score microscopic monitoring method, is deemed effective in reducing the ultimately targeted infection rate of poultry red mites.

Objectives: The present study was conducted to investigate farm work environments among farmers and examine the level of management of safety and health, and to subsequently produce study result to serve as foundational data for the development of guidelines on safety and health as part of the improvement of farming work environments among farmers raising Korean native cattle. Methods: The present study conducted a survey on farm work environments and the management of safety and health with 407 farmers engaged in Korean native cattle farming in selected regions in eight provinces. It also visited 10 farmers to verify the current status of farm work. Results: The survey results showed that 16.4% of the respondents experienced safety-related accidents due to farm work. The locations of the accidents were inside the cattle shed (71.4%) and facilities outside the cattle shed (19.6%). The types of accident showed collision with animals (35.7%), collision or contact with obstacles (27.1%), and musculoskeletal accidents due to heavy object handling (12.9%). The causes of the accidents were cattle (38.3%), cultivators and tractors (25.4%), facility tools in cattle sheds (9.0%), and slippery floors (6.0%). The damaged areas were hand (21.0%), spine (19.8%), lower limb (18.5%), and foot (17.3%). A self-diagnostic survey on respiratory diseases showed that 11.5% of the respondents experienced respiratory-related symptoms. The survey on safety and health during farm work showed that wearing personal protective equipment and response to emergency situations, which were needed to prevent safety-related accidents, were relatively low compared to the level of recognition of the need and awareness of safety issues. Furthermore, the field survey identified the current status of safety and health issues such as prevention management of collision accidents with cattle, how to handle heavy objects, and wearing of personal protective equipment. Conclusions: The present study identified safety-related accidents and problems in the management of safety and health among Korean native cattle farmers. In order to address the problem, it is necessary to not only provide guidelines on safety and health management which are appropriate to the characteristics of Korean native cattle farming work, but also to study the development of personal protective equipment.
