The main purpose of this study is to examine agricultural technologies through plowing and hoeing. One of the purposes on which this study is to analysis process of development and divergence of plough and hoe. The following facts are significant findings ; 1. In early Yi - dynasty, tilling implements used by ard plough and mould board plough did use in three south province, most region mainly used ard plough. Therefore, farming in early Yi - dynasty is extensive. 2. The mould board plough diffused in many fann house, spring farming and autumnfarming formed complet system in early 17th Century. But works of hoeing was continuing to save labor by long hand hoe. 3. Finally in 17th century, Small - scale independent farming ceaselessly tried to make his basis with transtortation intensive farming method. But Small - scale independent farming had not stafely base because extensive farming method continued in this peorid.

Advancing information technology have rapidly changed our service environment of life, culture, and industry. Computer information communication system is applied in medical, health, distribution, and business transaction. Smart is using new information by combining ability of computer and information. Although agriculture is labor intensive industry that requires a lot of hands, agriculture is becoming knowledge-based industry today. In agriculture field, computer communication system is applied on facilities farming and machinery Agricultural. In this paper, we designed and implemented application that provides personalized agriculture related information at the actual farming field. Also, this provides farmer a system that they can directly auction or sell their produced crops. We designed and implemented a system that parsing information of each seasonal, weather condition, market price, region based, crop, and disease and insects through individual setup on ubiquitous environment using location-based sensor network and processing data.

This study aims to determine the difference in profitability of Allium victorialis farming system between on-field and under-forest, and to propose several better ways for development of under-forest farming system of Allium victorialis. Survey was conducted 12 farmer in Gangwon, Chungnam, Jeonnam, Gyeongbuk to investigate production cost, management cost, input labors and so on. In this study, IRR, B/C ratio and NPV were used for profitability analysis. The result applied 25,000 won for under-forest farming system and 15,000 won for on-field farming system as unit price of sale showed IRR 36.2% and 54.2% respectively. The profitability of Allium victorialis from under-forest farm was not lower than other non timber forest products. And it will be possible to create high profitability such like that of Allium victorialis from on-field farm, providing the technical development for intensive farming is supported.

Background: Due to increased interest in animal welfare, there is now a need for a comprehensive assessment protocol to be used in intensive pig farming systems. There are two current welfare assessment protocols for pigs: Welfare Quality$^{(R)}$ Assessment Protocols (applicable in the Europe Union), that mostly focuses on animal-based measures, and the Swine Welfare Assurance Program (applicable in the United States), that mostly focuses on management- and environment-based measures. In certain cases, however, animal-based measures might not be adequate for properly assessing pig welfare status. Similarly, welfare assessment that relies only on environment- and management-based measures might not represent the actual welfare status of pigs. Therefore, the objective of this paper was to develop a new welfare protocol by integrating animal-, environment-, and management-based measures. The background for selection of certain welfare criteria and modification of the scoring systems from existing welfare assessment protocols are described. Methods: The developed pig welfare assessment protocol consists of 17 criteria that are related to four main principles of welfare (good feeding, good housing, good health, and appropriate behavior). Good feeding, good housing, and good health were assessed using a 3-point scale: 0 (good welfare), 1 (moderate welfare), and 2 (poor welfare). In certain cases, only a 2-point scale was used: 0 (certain condition is present) or 2 (certain condition is absent). Appropriate behavior was assessed by scan sampling of positive and negative social behaviors based on qualitative behavior assessment and human-animal relationship tests. Results: Modification of the body condition score into a 3-point scale revealed pigs with a moderate body condition (score 1). Moreover, additional criteria such as feed quality confirmed that farms had moderate (score 1) or poor feed quality (score 2), especially those farms located in a high relative humidity region. Conclusions: The developed protocol can be utilized to assess welfare status in an intensive pig farming system. Although further improvements are still needed, this study is a first step in developing a pig welfare assessment protocol that combines animal-, environment-, and management-based measures.

Agricultural products are inferior in their competitiveness in the world market mainly due to die high production cost which could be attributed to the rising land and labor cost in Korea. The small scale farming system with the lower production infra structure requires relatively intensive input labor for the reduction of production cost of agricultural products and impediment in the mechanization of farming systems. There are limitations in the cultivation techniques that seek out other directions for the raising competitiveness in the world market of basic food crops. Future goals to raise competitiveness of basic food crops in Korea should include the following: 1. Fostering of the farmers organization by crop items. 2. Agribusiness should integrate management with priority given to farmers. 3. Raise competitiveness to find out the system of obtaining on from the consumers.

The agricultural development of Korea has occurred at the expense of natural resources and environmental quality, and, today, one of the most urgent problem in the practices of intensive livestock farming is disposing of the animal wastewater. As a result, soil and water degradation and other environmental deterioration become apparent and they cause long-term loss in agricultural production. This paper attempted to summarize the environmental problems associated with agricultural activities, and to get some implications to minimize agricultural environment problems. It is proposed that sustainable agricultural is one of desirable directions for future Korean agriculture. The goal of the sustainable agricultural effort is to utilize the potential environmental quality problem. Agricultural operations may be more dependent upon the production practices and waste management techniques utilized by farmers than the size of the operation, the number of animal fed, or amount of waste involved. Also low-input farming technology can be suggested one of them, and disposing system of agricultural residues and animal waste should be developed with intensive concerns and financial supports.

In view of increasing environmental pollution, the organic farming in animal production is becoming increasingly urgent. The problems of veterinary medicine have not diminished through the most dangerous epidemic diseases. Organic farming attempts to function in harmony with the environment. The first criterion of the organic farm is that the animal must be self-sustaining. Their food must be produced to a large extent on the farm. The position of ruminants in biological systems is determined by the fact that this group of farm animals is provided with a digestive system which optimizes the utilization of the products of gut microfloral fermentation. The cattle do not require large amounts of concentrate feeling nor gross ugly farm building for intensive rearing. The economic profitability of a cow depends. on the first instance, on the level of milk production and the number of lactations. The length of life is an important factor since the tilde to maturing is relatively high in a cow. The result is that dairy cows in organic farming have greater length of live, and produce more milk in their life time than the shorter lived high input cow. This paper. therefore, discussed the problems of modern cattle farming and development trends of organic farming in Germany and Korea.

An Idea of Standard Rural Area(SRA), the rural areas which have higher ruralities of the rice cropping region and also higher urban characteristics, was conceptualized to develop the tentative basic indices necessary for rural settlement design in reclaimed land. The SRA's were determined by a technique of the principal component analysis with relevant data from 81 counties or cities located in the west side of Korea(Chon-Nam,Chon-Buk, Chung-Nam, Kyung-Ki Do).By the definition of the SRA, the principal component analysis is seperately carried out by two subworks, analyses of rurality and urban characteristics. From the analysis, rurality of the SRA is characterized by four components which appears to describe the scale of farm management, intensive farming, soundness of farming and farming basis on rice cropping, while urban characteristics of the SRA by three components to describe the accessibility, keeping ratio of infrastructures and level of medical services. Through grouping and synthesizing two characteristics of all counties by each component score, 24 counties were classified as urban-rural harmonized region which is the same result as that obtained from the extraction index being more than 50% of available area to total area except 1 county. Therefore, SRA is defined as the group of counties having more than 50% of available area to total area.

This paper provides two case studies of environmental impacts with socio-economic values. The first case is on flood protection levees conducted from 2003 to 2004 in Phu Tan district, An Giang province. The impacts were found by comparing full flood protection levees area (FFPL) to non-full flood protection levees area (NFFPL). Participatory Rural Appraisal (PRA) tools per each group of rich, middle, and poor people were used to list the impacts. Then, major impacts were selected by ranking and interviewing 60 households per site, and assessed by Cost Benefit Analysis (CBA) in rice production from 1996 to 2002 between two areas. The tested research indicated moving system of NFFPL to that of FFPL lost about 11 million VND/ha/year. The second case is on impacts of Penaeid shrimp farming conducted in Duyen Hai District, Tra Vinh Province in 2004-2005. Ninety households and 12 local officials were interviewed. Four PRAs were conducted and 36 water samples were taken inside and outside shrimp pond to measure values of DO, COD, Fe total, TSS, N-$NO_3{^-}$, N-$NH_4{^+}$, P-$PO{_4}^{3-}$, and Chlorophyll-a. Research results showed only 36.7% of the households got profit from shrimp farming. Highest financial efficiency was 0.72 for the semi-intensive system. Tested water indicators showed surface water quality did not match Vietnamese standard for surface water in coastal area (TCVN 5943-1995) and in rain. The water was very muddy and contaminated by organic aluminum. Summarily, the impacts were clarified more obviously via adding socio-economic values to assessment. Importantly, the values were transformed to household's income which is an indicator for policy-makers to consider the impacts obviously. Besides, data of different group of people impacted are cases contributing to consideration of the impacts in an appropriate social level.

A major challenge in the transition from conventional to organic production in a grain intensive region such as the Com Belt legion of the U.S.A. is how to profitably select and manage a crop relation. The opportunity cast of forgoing grain production for forage and green manure crops is significant. Many organic researchers and writers emphasize the need to bring an animal enterprise into the farming system for diversification and enhanced labor utilization. Livestock also add value to grain and forage crops to offset decreased grain production and can recapture nutrients used in crop production that can be recycled through manure. In grain intensive regions, organic farmers should consider swine production as a natural fit for the farming system. Swine are very efficient and adaptable animals that can add value to both grain and forage crops. While somewhat lacking, there is a reasonable body of literature on organic and sustainable swine production. However, there is relatively little specific information available to organic farmers to assist in the initial decision to enter organic swine production and to evaluate marketing alternatives. The primary focus of this paper is to give some background on organic animal production(emphasis on swine) in the Central United States and outline production and marketing decisions and considerations, relative to market trends, demographics and standards(U.S.). At the farm level, decisions must be made regarding resources, such as land, labor, financial and social capital, all relative to opportunities, all in the context of the standards and market forces beyond the farm. At the personal level the farmer must also make decisions about convictions regarding organic or environmentally friendly agriculture, willingness to change, impacts on lifestyle and family, and the transition to organic methods within the planning horizon of the farmer and the family business.
