Participation Of Family-Women In Agricultural Production : A Case Study Of Jaffna District, Sri Lanka
Family women play significant and crucial role in  agricultural development and allied fields. Several factor both economic and non economic factors are responsible for women participation. However, it is most unfortune that role of women in agriculture has not highlighted..Therefore the effort were made to analyse the work performed by women in agriculture. This study was under taken in Valikamam area of Jaffna district. A total of 185 household were selected through proportionate random sampling. The selected respondents were interview personally using pre tested well structured questionnaire. The data were analysed using appropriate statistical tool -probit model. The finding showed that the women contribution to the agricultural production is highly in family-women. The family-women age, income level and tenure rights had inverse relationship with participation in agriculture while, educational level, years of experience, distance of the woman’s farm from homestead, member of cooperative ,woman contribution in agriculture ,extension services and level of contribution had positive and significant relationship. Keywords :agricultural production , family-women, valikamam , probit.
Factors accelerating agricultural innovation and sustainability: The case of paddy farmers
The primary purpose of this study is to reveal the factors accelerating both the innovativeness and sustainability levels of paddy farmers. The data used in the study were obtained from the questionnaires conducted with 70 paddy farmers in the Bafra district of Samsun province, Turkey, determined by a simple random sampling method. Paddy farmers were divided into three groups as low, medium, and high innovativeness groups with hierarchical cluster analysis. An ANOVA was used to compare the socioeconomic and farming characteristics of the paddy farmers, and accelerated failure time models were used to analyze the factors affecting the innovativeness and sustainability variables. The research results indicated that the number of years of formal education, the agricultural experience, the amount of labor per unit area, the animal assets, the share of agricultural income in the total income, the number of memberships to farmer organizations, paddy production area, sustainable agriculture area, and cooperation scores differed from the innovativeness groups. The farmers' collaboration in agricultural activities increased the likelihood that they are an innovator. The results concluded that the number of years of formal education, global good agriculture practice, agricultural experience, household size, animal assets, and women's employment influenced both the innovativeness and sustainability variables. Encouraging the participation of women in agricultural production in rural areas, including sustainability‐related issues in addition to technical issues in farmer training programs, and ensuring the participation of women in such training are issues that should be considered in future.

Experimental study of thermal modeling for stratospheric platform airships
R&D work on the Japanese stratospheric platform airship is discussed from the viewpoint of the thermal modeling. The work includes two experiments on the thermal characteristics of the 25m-long airship and the 35m-long PV-equipped airship model. The validity of the current thermal model was confirmed by comparing the calculated results with the measured data. The other important work is the Ground-to-Stratosphere (GTS) flight test. A 47mlong airship-shaped balloon was flown to the stratosphere. The flight simulation program into which the thermal model was integrated, was developed and applied successfully to predict the ascent behavior and the flight trajectory.
