More and more distinctive villages are losing their historical background and regional architectural culture in modern society. Taking the renovation planning of Wenchang village as a case study, its function structure and land use are determined by the theory of "three layers of HSR(high-speed rail) station" after deep mining its history and culture. Then, the design method of rebuilding characteristic space in traditional villagesaiming at finding a proper way to handle the relationship between development and protection of traditional villagesis investigated from the perspective of natural landscape, spatial form and architectural features.展开更多

Urines were collected for iodine assays from women aged 15-40 years before and at 6 and 12 months after the connection of the iodinating device; goiter assessment was performed on the women at the start and end of the 1-year study. Water samples were collected for iodine assays at 2-weekly intervals. In all three villages, significant and sustained increases in median urinary iodine excretions,reaching levels recommended for an iodine-suffcient population, were observed; goitre prevalences were reduced in all the villages (by 22.6% to 35.8%). The iodine levels in the water ranged from 34 μg/l to 212 μg/L. In the control village, median urinary iodine excretions remained essentially unchanged but a small increase in goiter prevalence was observed. The iodized water was well received by the villagers and no adverse effects of water iodization were observed. The system functioned unattended throughout the one year period. The cost of providing supplemental iodine via the iodizing device is approximately 60 cents (U.S.) per family per year which is affordable by either the Government or the villagers. It is concluded that the iodizing system offers a new cost-effective strategy for the control of endemic iodine deficiency in Sarawak and may have applications in other areas with similar water sources展开更多
