APPROACHES TO RURAL DEVELOPMENT IN TAIWAN (A CASE STUDY) AgEcon
Nair, K. Damodaran.
The purpose of this paper is not to inquire into the role of agricultural sector in the economic growth of Taiwan. That has been done by many in the past. Rather, the main purpose of this paper is to review and discuss a few institutional approaches to agricultural and rural development on Taiwan which are considered to have played more significant roles, viz. The Joint Commission on Rural Reconstruction, the Farmers' Associations, Land Reform Program, Research and Education and the Four Year Economic Plans. An attempt also will be made to identify the effects of these institutions on the socio-economic life of the people in the rural Taiwan. Agricultural and rural development has been a subject for study and discussion among those who have focused...

Ascidians of the family Styelidae from the Caribbean Naturalis
Sloot, C.J. van der.
During a voyage to the West Indies undertaken in 1963-1964 Dr. P. WAGENAAR HUMMELINCK collected many specimens of marine organisms from Piscadera Baai, Curaçao, as a basis for the compilation of a preliminary list of the local fauna and flora. This paper deals with the styelid ascidians which dr. HUMMELINCK entrusted to me and whose study has formed the subject of a student’s nine-month practical course in taxonomy. Only three species, amongst the material collected from Piscadera Bay, seemed to be well enough characterized for them not to need revision. They are Styela partita (Stimpson), 1852, Polyandrocarpa (Eusynstyela) tincta (Van Name), 1902, and Symplegma viride Herdman, 1886. It has, therefore, been necessary to compare my material with earlier...

Atmospheric Effects on Fate of Aerially Applied Agricultural Sprays CIGR Journal
B. K. Fritz; USDA-ARS, College Station,; W. C. Hoffmann.
The deposition and drift of aerially applied crop protection materials is influenced by a numberof factors including equipment setup and operational parameters, spray material, and meteorological conditions. This work focuses on evaluating the meteorological influences on the transport and ultimate fate of aerially applied sprays. There was no single meteorological factor that dominated the downwind transport of the spray treatments replicated in this study. Generally, lower relative humidity decreased downwind deposition and the amount of spray unaccounted for due to evaporative effects. Increasing wind speeds decreased both in-swath deposition and downwind deposition, and increased the amount of mass unaccounted for.Increases in stability were only...

Autonomous Guidance of a Corn Harvester using Stereo Vision CIGR Journal
F. Rovira-Más; S. Han; J. Wei; J. F Reid.
The growing demand for applications in Precision Agriculture has been proportional to the emergent interest in automatic guidance of agricultural machines. The difficult, and at the same time strenuous, task of driving a harvester during the prolonged working days of the harvesting season justifies the special attention paid to this technology. The development of Global Navigation Satellite Systems has meant an important push for autonomous navigation, especially in the case of off-road vehicles. However, experience has shown that automatic guidance inside the tight arrangement of crop rows is difficult to achieve unless local positioning sensors take part in the localization unit of auto-steered machines. This research develops a perception engine based...

Autonomous Inter-Row Hoeing using GPS-based side-shift Control CIGR Journal
H. W Griepentrog; M. Noerremark; J. Nielsen; J. S Ibarra.
Several developments and investigations have been done to automate the lateral control of hoes with the aim to achieve higher weeding efficiency and decreased labor costs. The aim of this project was to investigate the accuracy and limitations for a computer controlled hoeing operation based on a GPS system. A conventional hoe and an electro-hydraulic side shift frame was used and attached to a small automatic tractor. The main task of the controller systems was to minimize the lateral deviations between current GPS positions of the hoe related to a predefined route. The range of the cross track errors (standard deviations) altered between 0.009 m and 0.028 m for the hoe (ground measurements). The hoe system enables hoeing up to 83% of a field surface area...
