Most of the current cultivation log is recorded by growers manually or whose environment information is input based on the grower's own judgement. It is not easy for growers to record the image of disease and insect pests in the cultivation log. In this regards, u-Farm cultivation log management system based on Web 2.0 and smart phone is introduced in this paper, that is used for the effective cultivation management and grower's convenience. In the system, the value of environment information is transmitted to servers via sensors. It designs and implements Web 2.0 Flex so as to make the cultivation log more reliable and provide users with active, convenient GUI in case the log is recorded by desktop. In this process, detailed modules are designed by object-oriented UML considering the reusability and maintenance of the system. Moreover, the system introduced in this paper is proved to be more excellent by the qualitative assessment compared with the other researches.

A new cultivation diary system based on environment sensor data and Web 2.0 with Flex is suggested, to improve the previous system using the subjective data of cultivators. The proposed system is designed by applying an object-oriented model called mini-architecture, in order to enhance the reliability of software as well as promote stability to overall system design. The environment sensor data such as temperature and humidity are used to develop the new reliable diary. Also, an active interface based on Web 2.0 and Android as the user GUI are implemented to maximize the convenience while recording the cultivation diary. The result of the performance evaluation shows that the data from sensors has 99.1% of correlation with that of analogue.

This study examined the time allocation pattern of farm wives. In particular it addressed i)the differences in extent of time spent in farming housework child care and leisure between on-farm and off-farm seasons ii)differences in the extent of time spent in such activities among farm wives and urban wives and iii) the determinants of time spent in such activities. To achieve these goals a system of time allocation equations based on household production theory was employed. On hundred and eight farm wives wiere selected in 1993 by the methods of judgement sampling and cluster sampling. Two major questions in the survey elicited sociodemographic information and time-use of farm wives using the time-diary method, The results indicate that farm wives different decisions about how to allocate their time to farming housework child care leisure during on-farm and off-farm seasons. In addition it was that farm wives are more likely to have dual responsibilities than are urban wives. Finally in the off-farm season education number of younger children and region were significant variables in explaining the time allocation decisions of farm wives. However only age was a significant factor in their time allocation decisions during the on-farm season. This leads one to conclude that time allocation is not a choice for farm wives in the on-farm season.

Although the rate of women farmer's participation in agricultural activities have been increased upto 52.7 % as of year 2003, Korean society has not fully recognized their roles in rural society. According to the agricultural basic law, most of rural women were engaged in agriculture as full time job, however, only about 11% of them could have supporting evidence of themselves as farmer having legal right. If women farmers faced some unexpected things such as a traffic accident, insurance company would not reward them as farmers unless they provide written proof of their job as farm worker or farm owner. Based on lawyer's legal advice, the authors developed a diary called "Saenghwalilji", a daily diary based on their time use and bookkeeping to prove the fact of their contribution to income generation of the farm. After examination of the diary, 18 persons out of 29 volunteers kept two types of dairy for the period of two weeks, and they reported it was very useful. Finally the better one of two was selected after reflecting the suggestions from the respondents. The "Saenghwalilji", will be very useful proof of women farmer's contribution to income, at the same time improving their farm management through better use of daily life time.

In Korea, a need of automatic dairy farm management system has been increased to lower production cost and to strengthen international competition. However, the present management system was mostly relied on foreign technologies and caused some problems in post management and after-sales services. Therefore, though there is a problem of price and quality at present, domestic technologies of the management system should be developed for the long run. This study was conducted to develop an electronic identification unit for an automatic dairy farm management system. The developed system was consisted of a tag, a reader, a switching circuit, and a personal computer. The tag attachable to each individual cow was developed to transmit individual radio frequency(RF) code into the air with modulation of ASK(amplitude shift keying). And the switching circuit was added to avoid confusion on reception and transmittance. The reader attached to a feeding device was developed to transmit activating signal periodically and to identify code of the individual tag when the tag was approached to the device. The reader was consisted of an active filter, a detecter, a comparator and a microcontroller. The test result was feasible enough to apply it for the automatic farm management system and the identified maximum distance was about 37cm.

The purposes of this study are to analyze the time use patterns of rice and barley for farm couples. The data used for this study were collected from farm households during the farming seasons (17th to 30th June) and the off-farming seasons (28th November to 11th December) of 2005, using a time diary. The sample for this study consisted of 118 couples, whose principal crops were rice and barley, living in rural area in eight provinces. SPSS Win 12.0 was utilized to analyze the data. The statistical methods used were frequency, percentage and paired t-test. The major findings of this study were as follows. First, the personal care time of wives was shorter than that of husbands, regardless of the fanning period, with the couples showing more personal care time during the off-farming season than during the farming season. Secondly, the total work(paid work plus housework) time of wives was longer than that of husbands during both the farming season and the off-farming season, showing that the labor burden of wives was bigger than that of husbands. Compared to the farming season, the total work time for both husbands and wives was shorter during the off-farming season, due to reduced farm work time, but the housework time increased for both husbands and wives. Thirdly, the leisure time of husbands was longer than that of wives during both seasons. The leisure time increased for both husbands and wives during the off-farming season, but the portion of the increase was bigger for husbands than for wives.

In order to advise how to solve the problems and suggest on the mechanization of beef farm, the facilities and equipment for feeding and supplying water to the animals and transporting manure, and farm machineries of sixty-seven beef cattle farms in western Chungnam Province were surveyed. The results are as follows; 1. The proportions of number of heads per farm for above 70, 50∼70, 30∼50, 10∼30 and below 10 heads were 26, 18, 29, 13 and 13, respectively. The farms with the annual income more than 30 million won are consisted of 67.6% of the farms surveyed which showed to be higher than national average. 2. Only 19% of farms had automatic feeding system. Water was supplied by water cup(45%), opening and shutting water tab(27.6%) and bucket. 3. Cattle manure was transported by manpower (46%) by loader (34%) and by gravitational flow (14%). Most of manure(97%) was composted after treatment of drying or piling up outside. 4. More instruction and education were required because of the insufficient routine checking and fixing for farming machines, and unsystematic education for learning skills. 5. 65% of farms felt unsatisfied about after service(A/S) for their machinery. The main reason why the farmers were not satisfied was that it took too much time to be repaired. 6. When the farms purchased facilities, equipment and machinery, they did not analyze economic value of them and keep a diary. To make effective use of machines, the most available model for purchasing and managing of machines must be developed and applied to various scales of management.

The purpose of this study is to examine the allocation of time between work and leisure by the rural elderly in Korea. The data used for this study are collected from fm households during the peak ($17^{th}\;to\;30^{th}$ June) and off-peak ($28^{th}$ November to $10^{th}$ December) farming seasons of 2005 using time diary. The sample for this study consists of 120 elderly over 65 years old living in rural area in eight provinces. The major findings are as follows. (1) The time spent of farm work by rural elderly in much longer than average work hours of elderly in general regardless of farming season. The indicates that the elderly farmers are the sustaining forces of agriculture as the urban industrial sector absorbs the younger labor force rural area. (2) There are significant differences in the work time(including form work, housework, and farm work plus house work) by gender, age, education, marital status, living arrangements. (3) The rural elderly spends less time in leisure compared to the elderly in general even during the off-peak season. (4) Especially during the peak season, time allocation between work and leisure by the rural elderly is heavily skewed, resulting in an inadequate amount of time for reproduction of labor. (5) There is only significant age difference in the amount leisure time regardless of farming season. (6) Male elderly farmers work approximately 30 minutes to 1 hour longer on farm than the females do, but the total work time (farm work plus housework) of female elderly is longer than that of the male elderly. There is no significant gender difference in the amount of leisure time during the peak season, whereas the men have more leisure than the women during the off-peak season. To conclude, the gender differences in time allocation among the rural elderly are minimal. However, the rural elderly of both genders suffers from excessive work hours and heavy workload compared to the urban counterpart.

As a series of studies to develop pest management system for sweet persimmon production matched with the quarantine criterion of sweet persimmon-imported county, a survey was conducted by questionnaire on pest management practice and scheme of increasing income in sweet persimmon farms in Korea. Above 80% of sweet persimmon farmers was over fifties in age. The greatest limiting factor for sweet persimmon production was thought to be disease by the farmers. Percentage of farmers who answered that the most important pest is anthracnose cause by Gloeosporium kaki, and stink bugs was 64.6% and 73.5%, respectively. In particular, the farmers did not consider Dichocrocis punctiferalis, a main targer insect for quarantine in USA, as serious problem. Obtaining information on pest management practice or decision-making on both selection of pesticide and time of pesticide application depended highly on their own experience with the highest proportion. Eight to nine times of pesticide applications a year was highest among farms with 56.6%. More than 80% of farmers recorded the diary of pesticide application. farmers considered increasing cost for pest management as the greatest problem with 35.4% in proportion, and 34.5% of farmers pointed out that increase in export is essential for increasing farm income with highest proportion.
