This study was carried to devise comprehensive policies for systematically fostering the eligible farmers in Korea based on their vocational developing stages such as potential stage in juvenile days, preparing stage in agricultural schools and colleges, farm worker stage under farm manager, ownership farming stage and professional farm manager stage. Of course all of these developing stages are not necessary but desirable processing to be a good farmer. At least more than two stages are necessary to be a professional farm manager. In order to systematically foster the eligible farmers as many as demanded in Korea, appropriate policies in the every stage should be devised. As the result of this study, several programs were sugested as the appropriate policies such as development of school 4-H program in potential stage, scholarship program in preparing stage, supporting programs for the farmhouse-hold having a family's farm management agreement, development of the instalment savings program for the young farm workers and farmer's certificate program, etc.

본 연구는 HACCP 제도를 적용하고 있는 소규모, 중규모, 대규모 양돈농장의 HACCP 제도 도입 목적, 효과, 그리고 문제점 등을 비교분석하기 위한 목적으로 실시하였다. 소규모와 중규모 양돈농장은 HACCP 도입 목적의 1순위를 정부의 예산을 지원받기 위함이라고 하였으나 대규모 농장은 농장의 경쟁력 향상이라고 답하였다. HACCP 적용 효과는 소규모 농장의 경우 체계적인 농장관리를 1순위로 응답하였으나 중규모와 대규모 농장은 농장의 위생관리 수준 향상이라고 답하였다. 아울러 HACCP 적용에 따라 발생되는 가장 큰 문제점으로는 직원의 의식향상의 어려움(소규모 농장)과 HACCP 도입에 따른 기록관리(중규모, 대규모 농장)인 것으로 조사되었다. 이러한 문제점을 개선하기 위해서는 양돈농장 HACCP 평가항목 수의 조정과 종업원을 대상으로 HACCP 교육을 실시할 필요성이 있을 것으로 판단된다.

The purpose of this study is to establish family life cycle of farm and to analyze changes of economic conditions-income, consumption expenditures, savings, assets, and debts-in farm household according to the family life cycle. Income, consumption expenditures, savings, assets, and debts functions are also estimated by age of household head. The data of Farm Household Economy Survey which was conducted in 1983 by Ministry of Agriculture and Fisheries is used in this study. Among total data of 2000, 1603 are analyzed for mean, percentage, and regression using CRISP Program at Office of Rural Development. The results of study can be summarized as follows; 1) Eight stages of family life cycle of farm are established according to the growth of the first child. They are: Establishment stage, Child bearing and preschool stage, Elementary school stage, Middle and high school stage, College and vocational adjustment stage, Period of children's marriage, Re-adjustment stage, and isorganizing stage. 2) The economic conditions of farm household are significantly fluctuated by family life cycle. Among the eight stages, stage Ⅱ is considered relatively comfortable living period and stage Ⅲ, Ⅳ are the most difficult periods of farm household economy. 3) The estimated functions of income, consumption expenditures, savings, assets, and debts by age of household head are as follows; Y(income) = 2, 354, 832+98,456T-1,036T2(F=11.746) C(consumption expenditures) = 81,876+154,976T-1,552T2 (F=37.272) S(savings) = 2,272,956+56,511T+516T2(F=4.262) D(debts) = 903,929+28,300T-438T2(F=3.339) A(assets) = 200,816+1,213,336T-12,930T2(F=21.069) To carry on a reasonable farm household management, a suitable measure to cope with the desire of family and the economic conditions of farm household should be prepared.

This research tried to present some basic data necessary to give effective support to urban retirees who already returned to the farm by looking into factors effecting on their adjustments to the lives before they returned to the farm and after they did so to know how well they adapt to the rural lives. For the purpose, we made a survey of 408 returners to the farm over the age of 50 for 6 days from October 18 to October 23 in 2004 using questionaires. The results show the followings. First, there are significant difference in the satisfaction with the rural life occurred by the sociological demographic changes according to 'health condition', 'subjective economic ability' and 'previous job'. Second, the difference of satisfaction with the rural lift which was taken place by the reasons before they moved to the farm is effected considerably by what made them decide to return to the farm first whether they prepared for it or not and how much money they have to do so. Therefore, to succeed in adjustment to the rural lives, their decision should be made by positive causes, they have to prepare concretely for it before they carry out their plans and they had better have enough money to move. Third, the difference of satisfaction with the rural life occurred by the reasons after they moved to the farm is effected by 'satisfaction with the forming information', 'the number of friends or neighbors', 'the frequency of meeting the friendly', 'the level of intimacy with neighbors' and 'their efforts to improve the relations with other residents'. And the sensitiveness to perceive the inconvenience according to the rural life is related strongly to the satisfaction with the rural life in the above 6 areas. Fourth, the repression analysis implemented to find how much the above 3 factors effect on the satisfaction with the rural life shows that it is 'returner's current health condition', 'farming education', 'farming fund' and 'effort to be intimate with other residents' that are very important.

Intensive farming methods that do not guarantee animal welfare can induce stress in pigs. Stress, in turn, can reduce their disease resistance and influence their hormones and metabolites in such a manner that productivity is negatively affected. This study was conducted to compare the stress related factors and blood characteristics of pigs raised on conventional farms and those raised on animal welfare farms. We measured the levels of cortisol, epinephrine and norepinephrine, biochemical parameters in blood and glycogen, L-lactate and heat shock protein 70 (HSP70) in muscle, as physiological markers of indicating the stress in conventional farm pigs (Control, n=10) and animal welfare farm pigs (Welfare, n=10). We found that there was a significant difference in the albumin-globulin ratio (A/G ratio), as well as the albumin (ALB), blood urea nitrogen (BUN) and aspartate aminotransferase (AST) levels between the two farms. Epinephrine was significantly higher in conventional farm, while level of norepinephrine was higher in animal welfare farm. There was no significant difference in cortisol, which is known as a stress hormone, across the two groups of farms. Muscular glycogen content was significantly high in animal welfare farm pigs. While L-lactate tended to be low in the animal welfare farm pigs, the difference between them and the conventional farm cohorts was not significant. HSP70 showed high levels of expression in conventional farm. Thus, we suggested that blood parameter results showed a stress response in the livers of conventional farm, and that catecholamine hormones, glycogen, L-lactate and HSP70 can be used as physiological factors of assessing animal welfare.

Objective: This study was conducted to obtain an objective index that can be quantified and used for establishing an animal welfare certification standard in Korea. For this purpose rumen pH, ruminating time, milk yield, milk quality, and blood components of cows reared in farms feeding high forage level (90%) and farms feeding low forage level (40%) were compared. Methods: Data on rumen pH, rumination time, milk yield, milk fat ratio, milk protein ratio, and blood metabolism were collected from 12 heads from a welfare farm (forage rate 88.5%) and 13 heads from a conventional farm (forage rate 34.5%) for three days in October 2019. Results: The rumination time was longer in cattle on the welfare farm than on the conventional farm (p<0.01), but ruminal pH fluctuation was greater in the cattle on conventional farm than the welfare farm (p<0.01). Conventional farms with a high ratio of concentrated feed were higher in average daily milk yield than welfare farms, but milk fat and milk production efficiency (milk fat and milk protein corrected milk/total digestible nutrients) was higher in cattle on welfare farms. Blood test results showed a normal range for both farm types, but concentrations of total cholesterol and non-esterified fatty acid were significantly higher in cows from conventional farms with a high milk yield (p<0.01). Conclusion: The results of this study confirmed that cows on the animal welfare farm with a high percentage of grass feed had higher milk production efficiency with healthier rumen pH and blood metabolism parameters compared to those on the conventional farm.
