Recurrent event data can be easily found in longitudinal studies such as clinical trials, reliability fields, and the social sciences; however, there are a few observations that disappear temporarily in sight during the follow-up and then suddenly reappear without notice like the Young Traffic Offenders Program(YTOP) data collected by Farmer et al. (2000). In this article we focused on inference for a cumulative mean function of the recurrent event data with these incomplete observation gaps. Defining a corresponding risk set would be easily accomplished if we know the exact intervals where the observation gaps occur. However, when they are incomplete (if their starting times are known but their terminating times are unknown) we need to estimate a distribution function for the terminating times of the observation gaps. To accomplish this, we treated them as interval-censored and then estimated their distribution using the EM algorithm proposed by Turnbull (1976). We proposed a nonparametric estimator for the cumulative mean function and also a nonparametric test to compare the cumulative mean functions of two groups. Through simulation we investigated the finite-sample performance of the proposed estimator and proposed test. Finally, we applied the proposed methods to YTOP data.

Recently some Korean feminists have reported the family management agreement (FMA) can contribute to enhance the women farmers' legal status and to improve their farm management. The FMA is a formal document written each rights and responsibilities on the farm management, income allocation, and labor condition such as working time and work-off days agreed among family members. Since 2004, 161 farmer couples have signed and practiced the FMA after two-day workshop scheduled for the agreement. The purpose of this study is to analyze the effects of FMA on the increase of participation in (am management among women farmers. Data were collected from 204 FMA couples through the structured questionnaires. Also interview and participating observation were carried out. Paired t-test were conducted using SPSS 12.0 for Windows program. Major findings were as follows. Women farmers' participation in decision making of farming activities has significantly increased after than before the FMA. However, husbands' participation in decision making is higher than women farmers even after the FMA. After the FMA, labor compensation, regularly or irregularly, for women farmers has increased to 53.3%, 35.3% higher than 18% of the previous study and women farmers' ownership of their farm assets has increased to 48.1% from 29.1%. Also, there is a tendency women farmers' role as a representative of their farm has increased. In conclusion the FMA makes women farmers participate more in farm management as decision maker, income beneficiary, farm asset owner, and farm representative, which encourage them to get the legal status as a farmer and to control their farm management risk. It is suggested that the FMA be selected as a program in order to strengthen the agricultural competitiveness.

In Uganda, the National Agricultural Advisory Service (NAADS) is responsible for agricultural advisory and extension services of the country. NAADS is a semi-autonomous public agency under the Ministry of Agriculture, Animal Industry and Fisheries (MAAIF) accounted for 45% of the MAAIF total budget. It aims to have a decentralized farmer owned/controlled agricultural advisory service system with increasing participation of the private sector. NAADS is greatly influenced by the extension framework of Neuchatel Group comprising representatives from the cooperation agencies and Official Development Assistance (ODA) donor countries. At the initial stage of the program, only 7 districts promoted the initiative and eventually spread out all over the country afterwards. These initiatives greatly contribute to the agricultural development and increase the farmers' income by 42-53%. However, due to the political intervention, the original goal was manipulated and criticized with briberies and corruption. Recently, the government of Uganda is considering a way to unify the agricultural advisory and extension services under the government programs.

The electronic commerce of agricultural products provides benefits both to the farmers and the consumers because of direct transaction between producers and consumers. This study analyses the factors affecting consumer's purchase intention that are using electronic commerce. And the purpose of this study is to contribute to increasing the farmer's income while operating electronic commerce by applying the results of this analysis. Consumer's purchasing factors in electronic commerce were obtained through literature reviews. The research model is established with the factors and analyses through the structural equation model. The results are as following; the first is how the quality of agricultural products affects positively consumer's satisfaction and trust. When sufficient information about the seller and the products are provided in the shopping mall site there are positive effects on the consumer's satisfaction and trust. The factors of convenience like purchasing time, saving, delivery convenience affect positively consumer's satisfaction. However, the relationship with trust enhancement could not be confirmed. In addition, hypotheses of positive relationships between economic feasibility factors like low price, satisfaction and trust, were rejected. Finally, consumer's satisfaction affects trust, and both the consumer's satisfaction and trust affects positively the purchase intention. In summary, in the electronic commerce of agricultural products, consumers might use electronic commerce as they purchase the reliable high quality products directly from farmers rather than be affected by economic feasibility and convenience factors.

The detector size effect due to the spatial response of defectors is one critical source of inaccuracy in clinical dosimetry and has been a subject of numerous studies. Conventionally, the detector response kernel contains all of the influence that the detector size has on the measured beam profile. Various analytic models for this kernel have been proposed and studied in theoretical and experimental works. Here, we use a method to determine detector response kernel simply by using Monte Carlo simulation and convolution theory. Based on this numerical method and DOSIMETER, an EGS4 Monte Carlo code, the detector response for a Farmer type ion chamber embedded in water phantom is obtained. There exists characteristic difference in the simulated chamber readings between one with carbon graphite wall and the other with Acrylic wail. Using the obtained response and the convolution theory, we are planning to derive the detector response kernel numerically and remove detector size effect from measurements for 6MV, 10${\times}$l0cm2 and 0.5${\times}$10 cm2 photon beam.
