The objective of this study is to propose activation ways through an analysis on processing actual conditions and quality of farm food. For the analysis we have surveyed the actual condition of farms and conducted sensory test on farm food. Difficulties of farm business are in order to 'preparation of papers', 'facility standard', 'improvement of quality' and 'labeling'. Overall, products from major food companies achieved better results than farm foods in all sensory test. It is necessary to educate the 'Food Sanitation Act' and prepare a manual for the development of farm food.

The study attempted to document the concept of farm tourism by categories and to evaluate the farm tourism projects developed in Kyungpook area, and also to formulate a device for improving such projects in Kyungpook area. For these purposes we have examined the existing patterns of farm tourism projects developed in Kyungpook area since 1986 and evaluated such projects conducted in same area. We also attempted to find out what were the problems conducting such projects. To estimate the demand patterns of farm tourism we have done a survey conducted in city and urban areas and documented consumer's preferences which patterns were willing to. Finally we suggested, in this study, several strategies for improving the farm toruism projects in Kyungpook area.

Wind energy can be conversed into electrical power using wind generator. Wind farm is made up of many wind generators, and it is often interconnected into distribution system to supply power for utilities. There are many protection problems on distribution system connected with Wind farm. It can effect on power quality severely when faults are occurred on distribution line or Wind farms. Therefore the correct protective scheme must be set for distribution system which has a Wind farm. In this paper, A wind farm connected into distribution line is simulated with several fault types which can be occurred on distribution line and Wind farm using PSCAD/EMTDC. And this paper proposes necessary relays to protect both sides of distribution system and wind farm.

The performance test of a wind turbine in a wind farm is generally carried out by the owner to verify the power curve of the wind turbine given by the turbine manufacturer. The international electro-technical commission provides the IEC 61400-12-1 standard on "Power performance measurements of electricity producing wind turbines". By using this code, one can easily find the suitable met-mast (meteorological mast) location for the wind data whether a wind farm is potential or already built. In this paper, the valid sectors for wind turbines installed in the HanKyoung wind farm, south-west in Jeju island are analyzed on the basis of the code by considering the wind farm layout. Among these sectors, the optimal met-mast location is presented for the power curve verification of the wind farm.

Though a variety of non-conventional feedstuffs have been successfully evaluated in research stations in Asian countries, there had been little adoption of these technologies at the small farm level. The methodology and results of three separate on-farm trials evaluation the possible use of some non-conventional feedstuffs in broiler diets under small farm conditions in Sri Lanka are reported in this paper. In all trials, the commercial mash, that in normally used in the farms, served as the control. In trials 1 and 2, 5 and 10% cassava leaf meal, respectively, was substituted (w/w) for the commercial mash and fed to broilers for six weeks. In trial 3, several non-conventional feedstuffs (cassava leaf meal, rubber seed meal, ipil ipil leaf meal and died poultry manure) were substituted (w/w) for the commercial mash at levels of 15-20%. The results demonstrated that these non-conventional feed resources can be used in broiler diets under small farm conditions, with no adverse effects on performance. The salient features of on-farm animal research are highlighted.

The purpose of this study was to analyze the effectiveness of training Program for return farm. In detail, this study evaluated the trainees' satisfaction, achievement, and effectiveness of the education. This Study polled 250 trainees who presented the Return farm training program. The results of analysis are as follows; First, the satisfaction and the reliability on the educational institutions of return farm was the highest. Second, Trainees' replied that their Agricultural Techniques was improved. Especially, 'business administrative ability, cultivation techniques & management ability, and agricultural machinery using ability were enhanced. Their self-confidence of return farm was increased. Third, the correlation of satisfaction, achievement and effectiveness of training program was statistically significant. The findings of this study will be used to plan of return farm education program.

A review of accidents involving farm machinery, which occurred in Korea during 2002, shows that $90.7\%$ of farm-work accidents and $9.3\%$ of traffic accidents were linked to agricultural machinery. The frequency of accidents per annum amounts to 72.2 out of 10,000 vehicles, $94.4\%$ of which relates to tillers and tractors. An analysis of the causes of the accidents revealed that $49.1\%$ of farm-work accidents were due to the tiller driver's fault or error. In the case of traffic accidents, $83\%$ of farm machinery mishaps were found to be due to violation of traffic regulations while $60.4\%$ of the farm machinery damage resulted from faulty driving or lack of safe driving practices. The average casualty count of farm machinery-related accidents is 1.39 persons per case, which consist of 0.07 deaths, 0.74 serious injuries, and 0.58 slight injuries.

This study focuses on the discovering problems which have been encountered while the farm company grew from one-man business to big company. We divide a growth process of farm company into 7 phases, and analyze the problems of each phase of growth process of farm company by theoretically and empirically. The logical model methodology is selected to test the basic model, and we use 6 cases to test suggested basic model. The results of this study are as follows. It suggests that the CEO of farm enterprise or its policy maker can understand what kinds of problem they meet while the farm enterprise grew from one-man business to big company, and they can make better strategies or better support policies.

This paper presents the method for the fluctuation smoothing control by using relaxation time variable control of battery. When the output power of wind farm is changed suddenly, it is necessary to control the output power of wind farm. The smoothing relaxation time is changed within limits of battery output power. Using the hybrid energy storage system (HESS) combined with battery energy storage system and electric double layer capacitor, it is possible to control the output power of wind farm. The capacity of battery is determined by considering the case of the disconnecting wind farm from the grid. To verify the proposed method, simulations are carried out by using PSCAD/EMTDC with actual data of wind farm in the Jeju Island.

According to increasing the number of rice farm households, it is important to find optimal farm scale, farm crops, and labour constraints depending on growth time. The study aims to analyze the optimal farming system using the linear programming in Seosan county, Chungnam. The survey was conducted in-depth interview to collect data from one farm household. Results show that farmers change their some crops in dry filed into ginger and hire farm labours in April. The findings should be of interest to rice farmers and policy makers to manage their farm effectively and to support them.
