万山汞矿区弹琴蛙重金属富集与组织关联分析
in
生物富集
2024
Q89%X171; 为了解万山汞矿区弹琴蛙(Nidirana adenopleura)组织重金属富集特征及其关联,对万山汞矿区典型农田生境内弹琴蛙组织(肝脏、皮肤、股骨、肌肉和趾骨)中铬(Cr)、锰(Mn)、镍(Ni)、铜(Cu)、锌(Zn)、镉(Cd)、铅(Pb)、砷(As)、硒(Se)和汞(Hg)这10种重金属元素的生物富集特征差异进行分析,结合非负矩阵分解分析法识别重金属元素的来源及贡献,并通过灰色关联度分析法分析弹琴蛙组织重金属元素间的关联性.结果表明:重金属元素在万山汞矿区弹琴蛙体内富集程度不同,平均质量分数由大到小依次为 Zn、Cu、Mn、Pb、Se、Cr、Hg、Cd、Ni、As;Cu、Se、Cr、Ni、Cd 和 Hg主要富集在肝脏组织中,Mn、Zn和Pb主要富集在股骨和趾骨组织中,As主要富集在肌肉组织中.基于非负矩阵分解和相关分析,Hg、Cu、Cr、Pb和Se主要源于汞矿开采,As主要来源于农业活动,Mn主要来源于锰矿冶炼,Ni、Zn和Cd来源于多种复合途径.总之,两栖动物趾骨具有较好的生物指示作用,可作为一种非致命性的检测方法,用于动物重金属污染的研究.研究结果可为万山汞矿区环境污染防控和野生动物保护提供科学依据.

薄壳山核桃不同无性系开花物候特性观测和比较
2015
对薄壳山核桃32个无性系的雌、雄花开花物候期和花量进行了观测和比较.结果表明:2011-2014年薄壳山核桃无性系开花物候期有所差异,但开花物候类型一致.2013年,供试的32个薄壳山核桃无性系整个花期持续时间为4月24日-5月21日.雄花花期持续时间为11~18 d,雌花花期持续时间为9~17 d;雌花最佳授粉期与雄花散粉盛期持续天数均为3~8 d.依据雌花与雄花开放的先后次序可以确定其中的16个无性系为雌先型,10个无性系为雄先型,6个无性系为同时型;并根据观测结果确定了其中86个可行的授粉组合.最佳的授粉配置方案为:将1号、5号、27号、29号、35号无性系作为马汉、28号、65号无性系的授粉配置无性系.32个薄壳山核桃无性系之间,雄花序长度无显著性差异,单枝雄花簇数、单个雄花序花粉囊数、单株雄花序总数、单枝雌花数、每簇雄花序数、单株雌花总数的差异均达到显著水平,总体变异幅度最大的是单株雄花序总数(变异系数为75.51%).

Observation and Comparison of Flowering Phenology of Different Carya illinoensis Clones / 薄壳山核桃不同无性系开花物候特性观测和比较
2015
Flowering phenology of thirty-two Carya illinoensis clones was observed and compared. The results showed that there exited some differences in flowering phonological phase from 2011 to 2014 and the duration of blossom process of all the thirty-two clones was from April 24 to May 21 in 2013. The lasting days of male flower of the thirty-two clones were 11-18 days and the whole flowering period of female flower were 9-17 days in 2013. The duration of receptivity stage of female flower and pollen shedding stage of male flower of thirty-two clones were all 3-8 days. According to the time order of blossom of male and female flowers, sixteen clones could be determined as protogynous type, ten clones were protandrous type and six clones the homogamic type. Eighty-six feasible pollination combinations could be selected according to the observation results. The best configuration scheme of clones was proposed. No significant difference was found in the length of male inflorescence among the thirty-two clones, but the

背景:本院推動住院病人二代戒菸措施以醫師為主要推動者,統計2019年1月至12月本院住院病人戒菸服務人數及衛教呈現負成長。目的:探討以統合性系統性文獻回顧應用戒菸護理措施的專案提升住院病人戒菸率。解決方案:透過實證護理臨床應用,選定統合性文獻戒菸護理措施修訂為本院可行方案。推動過程中遇到阻力,分別擬訂「辦理二代戒菸在職教育訓練」、「修訂服用戒菸藥物者轉介流程」、「增訂拒絕戒菸者轉介流程」。收集戒菸人數及戒菸成功率,比較專案實施前基礎數值和實施後12個月及24個月差異。結果:戒菸服務人數在12個月內從85人增加至105人,在第24個月進一步增加至125人。比較2019年和2020年的3個月點戒菸成功率,從專案實施前31.36%提升至實施後42.67%,增加11.31%;比較2019年和2020年的6個月點戒菸成功率從實施前27.16%提升至實施後42.67%,增加15.51%。2021年12月專案成果,3個月點戒菸成功率為44.40%,6個月點戒菸成功率為41.82%。結論:本專案的戒菸護理措施提升住院病人戒菸率,專案推動成功因素,主要是透過實證,搜尋到有品質研究證據,透過7A找出證據與臨床差異,再透過跨團隊合作專案模式進行推動,其次戒菸護理措施實證應用,凸顯護理角色對於品質提升重要性,亦可作為護理專案解決方案之參考。

背景 產後憂鬱為產後婦女常見健康問題,運用有效的社會支持降低產後憂鬱為重要議題,現今智慧型手機的普及,使介入處置的方式有更多可能性。目的 本研究旨在探討以Line為媒介的行動應用程式之社會支持方案,對產後婦女改善知覺壓力與憂鬱之效果。方法 本研究採實驗性研究設計,126位懷孕36週後且有使用智慧型手機習慣者,隨機分配為實驗組(n =61)與對照組(n = 65),實驗組於產後4週以Line提供每週2次的社會支持方案,對照組則無介入方案,並以中文版知覺壓力量表和愛丁堡憂鬱量表評值成效。結果 實驗組產後婦女的知覺壓力(F = 27.25, p < .001)與憂鬱程度(F = 35.73, p < .001)都顯著低於對照組。結論 以Line為媒介的行動應用程式之社會支持方案可有效降低產後婦女知覺壓力與憂鬱程度,依研究結果,行動應用程式之社會支持方案建議可被應用於產後照護。

Risk Capital and Foreign Indirect Investment: Theory and Evidence from Banks in Asia
本文提出國際投資組合的VaR公式解,以利金融機構在國際間接投資中管理市場風險。本模型可視為Kupiec(1999)和Chen and Liao(2009)模型的一般式,其比Kupiec(1999)和Chen and Liao(2009)模型更適合目前國際投資的狀況。本文以日本、台灣、韓國的銀行為例,實證發現當銀行中的外國資產的投資權重越大,則以VaR模型衡量的風險性資產更接近實際的風險性資本,而且次級房貸發生後,本模型更能準確衡量三國金融機構的風險性資本。此外,我們也發現外國資產的投資權重與相對VaR存在先下降後上升的趨勢,因此本文續而最小化VaR求得國內外資產的最適配置比例。實證發現,在金融危機期間,銀行業者會減少國外資產的投資比例以最小化VaR,但在經濟狀況正常時,反而增加國外資產的比重。

Effect of Inflation on the Cost of Inflation-Linked Annuities Considering Stochastic Interest Rate and Inflation Rate Models
2019
To protect the real income from retirement pensions against the risk of inflation, developing an annuity model that can be linked to the inflation index is necessary. Although inflation-linked annuities increase the cost of retirement pensions for governments, the risk posed by inflation to retirement annuities must be understood. In this paper, an inflation-linked annuity with a cap and floor model is developed. The model is a general form that can be reduced to special forms such as ordinary annuities, inflationlinked annuities without barriers, inflation-linked annuities with a cap model, and inflation-linked annuities with a floor model. Interest rate risk and inflation risk are considered within the model. Furthermore, we derive a closed-form solution for the model. The valuation framework can benefit annuity providers to understand the cost of inflation-linked annuities. The empirical results indicate that the prices of the annuities with cap and floor generally increase when the cap values increase. In addition, the sensitivities of volatilities are larger than those of the correlation coefficients. The valuation framework can benefit annuity providers to understand the cost of inflationlinked annuities.

The New Thought of Labor Insurance's Pension Benefits
2019
Under the recent pension reform of the Labor Insurance Act in Taiwan, it is proposed by the Ministry of Labor that the old-age benefits be based on the worker's average salary over his/her highest 180 months of earnings rather than his/her highest 60 months of earnings. Extending the time length in the average salary scheme may substantially reduce retirement benefits if the insurance salary is not adjusted before taking the average. In this paper, we propose a reasonable adjustment formula for calculating the worker's average salary. Our formula has several advantages such as embedding a dynamic adjustment according to the latest national average monthly salary and improves gender equality. We discuss how to determine the long-run relationship between pension insurance premium and retirement benefits for a financially stable pension system. We also suggest how to apply the proposed benefits formula to set up a financially feasible retirement payment formula that embeds a minimum payment (Floor).
