Precipitation Chemistry at a High Elevation Forest in Central Taiwan
No full text[[abstract]]High elevation ecosystems are particularly sensitive to environmental change. Mountain agriculture is extending to areas at high elevations in Taiwan but the effects on nutrient cycling of the surrounding ecosystems are largely unknown. We examined precipitation chemistry at Piluchi Experimental Forest in central Taiwan to evaluate the contributions of local air pollution and long-range transport of air pollutants on nutrient cycling at this seemingly remote forest. Sea-salt aerosols and anthropogenic pollutants resulting from long-range transport of air pollutants and mountain agriculture activities are the key factors affecting precipitation chemistry at Piluchi Experimental Forest. Precipitation chemistry was dominated by ions of oceanic origin in the summer and by anthropogenic pollutants SO4 2−, NO3 − and NH4 + in the winter and spring, the northeast monsoon season. The much higher concentrations of S and N in the northeast monsoon season than the summer suggest a substantial contribution from long-range transport as the prevailing air masses moved from inland China and passed over the industrialized east coast of China before arriving in Taiwan. The very high concentration of NH4 + (22 μeq L−1) in the spring, when the local application of N-containing fertilizers was high, signifies the influences of mountain agriculture. Despite very low concentrations relative to other sites in Taiwan, annual input of NH4 + (3.6 kg ha−1 year−1), NO3 − (7.2 kg ha−1 year−1) and SO4 2− (10 kg ha−1 year−1) via precipitation was substantial suggesting that high elevation ecosystems of Taiwan are not free from the threat of atmospheric deposition of pollutants

Can a Cognitive–Perceptual–Physical Battery Predict Driving Competence for People With Mild Cognitive Impairments? A Pilot Study
No full textAbstract
Date Presented 3/30/2017
Our research showed that some people with mild cognitive impairments can still drive safely. In addition, visuocognitive assessments, seldom included in driving evaluation in the literature, may predict performance in on-road assessment. Realistic on-road assessment is needed.

No full textThe Relationships between the Shih-huo-chih in the Sung-chao kuo-shih and the Shih-huo-chih in the Sung-shi
Full text linkDuring the Sung dynasty many versions of the national history were compiled. All these national histories included a chapter called Shih-huo-chih 食貨志. These versions of the Shih-huo-chih are not extant now in their original form, but fragments of them have been included in such books as the Sung-shih Shih-huo-chih 宋史食貨志, the Hsü Tzŭ-chih-t’ung-chien ch’ang-pien 續資治通鑑長編, the Wên-hsien t’ung-k’ao 文獻通考, the Yü-hai 玉海, the Huang-chao pien-nien kang-mu pei-yao 皇朝編年綱目備耍, and the Shang-t’ang ch’ün-shu k’ao-so 山堂群書考索. The original form of the Shih-huo-chih, therefore, can be traced to some extent. Among the above works, the preface to the Shih-huo-chih in the Sung-shih states that, though the chapter was based on the Shih-huo-chih in the Sung-chao kuo-shih 宋朝國史, the quotation was limited only to the facts worth quoting because otherwise the chapter would become too voluminous. Comparing, however, the chapter of the Sung-chao kuo-shih with the similar chapters of the above works, the Sung-shih Shih-huo-chih seems to have borrowed in its entirety this chapter in the Sung-chao kuo-shih. In other words, although the Sung-shih Shih-huo-chih is mostly based on the Shih-huo-chih in the Sung-chao kuo-shih, such chapters as the fang-t’ien 方田 were newly added, and the description of the Sung-chao kuo-shih is sometimes corrected or illustrated by new facts. Moreover, for the period after Li-tsung 理宗 at the end of the Southern Sung (1225~1279), the Sung-shih Shih-huo-chih has a unique description because the corresponding part of the Sung-chao kuo-shih is lacking.The author then compares the text of the Sung-shih Shih-huo-chih with that of the above books for the purpose of restoring the original form of the Shih-huo-chih in the Sung-chao kuo-shih. The Hsü Tzŭ-chih t’ung-chien ch’ang-pien not only quotes the Sung-chao kuo-shih most extensively but also exhaustively corrects its errors of the latter. The Wên-hsien t’ung-k’ao also greatly depends upon the Sung-chao kuo-shih without indicating the source, while the Yü-hai, indicating the source, borrows some passages. The Shan-t’ang ch’ün-shu k’ao-so quotes the sections covering the reigns of Chê-tsung 哲宗 and Hui-tsung 徽宗in the Sung-chao kuo-shih which are not clearly recorded in the other books. The Huang-chao pien-nien kang-mu pei-yao quotes, mostly in its notes, the description from the Sung-chao kuo-shih without indicating the source.Thus the Shih-huo-chih in the Sung-chao kuo-shih remains in the form of various versions quoted in other works and from these the author endeavors to restore part of the text of the Shih-huo-chih in the Sung-chao kuo-shih.journal articl
