https://irlib.pccu.edu.tw/handle/987654321/53335
title: 以探索式空間分析建構垃圾非法傾倒空間特徵評估模式:以臺灣原鄉山區為例 abstract: 非法傾倒所造成原鄉山區垃圾瀑布問題主要是農業資材、民生廢棄物或事業廢棄物被隨意丟棄在山谷或緩坡,如何透過空間規劃介入,改善清運資源分配與垃圾瀑布防治工作,提升山區垃圾循環經濟再利用。本研究透過探索性空間分析技術掌握垃圾清運資源區位分配問題以及垃圾瀑布空間分佈現象與影響因素為重要研究課題。未來可協助山區清運資源分配與清運最佳路徑規劃,以最小化運輸成本,並降低垃圾瀑布產生。該計畫焦點為原鄉山區垃圾瀑布空間特性進行檢視與分析,進而掌握垃圾瀑布空間分佈特徵進行分析,檢討原鄉山區垃圾瀑布產生環境條件及影響,以回應聯合國環境規劃署《山區廢棄物管理展望》之目標。

title: 家戶所得、通勤消費及住宅消費 abstract: 家戶所得與家戶的消費支出型態(住宅消費不均度)同時受到經濟發展變化及家庭內部屬性特徵的影響,根據中央大學台灣經濟發展研究中心2022年12月公布之台灣12月消費者信心指數(CCI)為金融風暴以來的新低,包含六項分項指標物價水準、購買耐久財、國內經濟景氣、家庭經濟狀況、就業機會和投資股市時機全數走跌。經濟學人(2017)報導在美國遠距離婚姻在2008年金融危機之後呈現上升,經濟衰退,使許多人得在遠方的工作和沒有工作之間抉擇,改變美國家庭型態。本研究室使用DID觀察在金融風暴前後及房地產景氣高峰前後,不同所得家戶通勤支出占總消費支出比例,回應現今經濟環境及住宅市場的劇烈變化可能對家庭型態的影響。

https://irlib.pccu.edu.tw/handle/987654321/53321
title: 土壤及地下水污染整治對周邊不動產價格與土地開發再利用效益影響之研究 -以新竹縣與桃園市為例 abstract: 本專案研究目標係希望透過污染場址整治與再開發對周邊不動產之影響,實證整治與再開發後所創造之效益,並透過財務機制、誘因配套等方式,促進民間主動進行污染整治之意願。茲研擬本計畫之研究目的如下: (1)蒐集土壤及地下水污染反映於價值與收益上之相關文獻,彙整其污染樣態、影響程度、評估方法等,以作為後續情境設定與實證分析之基礎。彙整國外棕地再開發案例,綜合分析其發展背景、場址樣態、再開發主體、過程、方法、配套、法令,以及所衍生之相關經濟效益,並探討適用於國內的可行性,進而提出相關法令與制度修訂建議。 (2)透過特徵價格法、成對交易案例分析與願付價格法,評估污染整治前後對不動產價格之影響,經由實證分析找出不同污染場址類型的影響程度、範圍與時間點。藉由敘述性偏好問卷設計,估計各種情境與條件下,民眾對於再開發後的願付價格,藉以確認污染整治與再開發後所能產生的租稅增額等經濟效益。 (3)探討污染整治配合土地再開發所致的不動產增值與租稅增額之經濟效益回收運用,評估作為土壤及地下水污染整治基金收入來源或棕地再開發財源之可行性。
The research goal of this project is to demonstrate the impact of the remediation and redevelopment of contaminated sites on surrounding real estate, and to demonstrate the benefits created after remediation and redevelopment, and to promote private initiatives in pollution remediation through financial mechanisms, incentive packages, etc. Will. The research purposes of this project are as follows: (1) Collect relevant literature on the value and benefits of soil and groundwater pollution, and compile their pollution patterns, impact levels, assessment methods, etc., as the basis for subsequent scenario setting and empirical analysis. Collect foreign brownfield redevelopment cases, comprehensively analyze their development background, site types, redevelopment subjects, processes, methods, supporting facilities, laws and regulations, as well as the related economic benefits derived from them, and explore the feasibility of applying them domestically, and then Propose suggestions for revision of relevant laws and regulations. (2) Through hedonic price method, paired transaction case analysis and willingness-to-pay price method, evaluate the impact on real estate prices before and after pollution remediation, and find out the degree, scope and time of impact of different types of contaminated sites through empirical analysis. Through the design of a narrative preference questionnaire, we estimate the price people are willing to pay for redevelopment under various scenarios and conditions, thereby confirming the economic benefits such as increased rents and taxes that can be generated after pollution remediation and redevelopment. (3) Explore the recovery and utilization of economic benefits from real estate value increases and rent tax increases caused by pollution remediation combined with land redevelopment, and evaluate the feasibility of using it as a source of income for soil and groundwater pollution remediation funds or as a financial source for brownfield redevelopment.
<br>體態評估技術提昇母豬生產力的研究
https://irlib.pccu.edu.tw/handle/987654321/53302
title: 體態評估技術提昇母豬生產力的研究 abstract: 本試驗於台灣南部一個種豬場進行,收集2021年4月至2022年2月,包含藍瑞斯與約克夏兩個品種共339頭母豬與4,403頭仔豬的繁殖資料及母豬於配種、懷孕108天及離乳時身體狀態的性狀,探討母豬體重、背脂厚度、主觀體態評分、卡尺評分對母豬繁殖性能的影響。所有資料應用SAS PROC GLM程序分析。結果顯示,母豬的體重、背脂厚度、目視評分及卡尺評分隨著胎次有上升或下降的趨勢,各評估方法在母豬泌乳期間的變化,體重方面藍瑞斯母豬各胎次的泌乳體重損失較約克夏母豬高,並且第1~2胎母豬的泌乳期間損失較其他胎次多;第1胎母豬懷孕期間的身體狀態變化大部分呈負成長,且泌乳期間的損失較多。懷孕108天時的背脂厚度,藍瑞斯為14~21 mm、約克夏為12~14 mm、不分品種則為17~20 mm;藍瑞斯、約克夏及不分品種母豬之卡尺評分皆為3分(5分制)較適當。本研究結果發現,母豬的背脂厚度與卡尺評分在適當的體態下,綜合的繁殖性狀結果較佳。泌乳期間的變化,於泌乳期間的體重、背脂厚度、卡尺評分損失較低的藍瑞斯母豬均有提升下一胎出生總頭數的趨勢(P > 0.05),約克夏母豬若於泌乳期間背脂厚度損失< 2 mm可減少離乳至再配種間距、分娩間距1.07天與4.43天(P < 0.05),卡尺評分損失< 0.5 unit也可減少分娩間距6.14天(P < 0.05),體重損失< 21.5 kg可增加下一胎出生總仔數2.78頭(P < 0.05),母豬群的泌乳期間身體狀態變化體重(< 24 kg)、背脂厚度(< 2 mm)及卡尺評分(< 0.5 unit)的母豬可提升下一胎出生總頭數分別為2.27頭、0.74頭、1.36頭(P < 0.05)。本研究結果證明體重、背脂厚度及卡尺評分,是監督母豬身體狀態,提升繁殖性能重要的性狀;台灣母豬群於懷孕期間的背脂厚度與卡尺評分指標,以及泌乳期間的損失與後續繁殖性能的關聯也同時建立。
The study was conducted at a breeding farm in southern Taiwan. Reproductive data from April 2021 to February 2022, including a total of 339 Landrace and Yorkshire sows and 4,403 piglets were collected. The body condition (BC) traits of sows at mating, 108 days of gestation, and at weaning, were analyzed to study the effects of sow body weight, backfat thickness, subjective body condition score, and caliper score on reproductive traits of sows. All data were analyzed using the PROC GLM procedure in SAS. The results showed that the sow's body weight, backfat thickness, visual score and caliper score tend to increase or decrease with the parity. The lactation weight loss of Landrace in each parity is higher than that of Yorkshire sows, and the loss during lactation of the first to second parity sows is greater than that of other parities. Most changes in the body condition of the first parity sows during pregnancy show negative growth, and the losses during lactation were greater. Backfat thickness at 108 days of gestation was 14~21 mm for Landrace, 12~14 mm for Yorkshire, and 17~20 mm regardless of breed. The BC caliper score of 3 points on a 5-point scale was more optimal both for Landrace and Yorkshire sows. Results of this study found that when the backfat thickness and caliper score of sows are in optimal body condition, the overall reproductive traits will perform better. The body weight, backfat thickness, and BC caliper score of Landrace sows with lower losses during lactation were all tend to increase in litter size of next parity, but it is not at significant level. For Yorkshire sows, the loss of backfat < 2 mm during lactation reduces WSI and FI by 1.07 d and 4.43 d (P< 0.05), the loss of caliper score < 0.5 unit can also reduce FI by 6.14 d (P< 0.05), and the weight loss < 21.5 kg increases the total number of piglets born in the next parity by 2.78 (P< 0.05). Sows with lower body weight (< 24 kg), backfat thickness (< 2 mm), and BC caliper score (< 0.5 unit) loss during lactation increase the total number of piglets born in the next parity by 2.27, 0.74, and 1.36 piglets (P< 0.05). Results of this study indicated that body weight, backfat thickness and BC caliper score are useful traits to monitor the body condition of sows and therefor to improve reproductive performance. The evaluation indicator of backfat and BC caliper score during pregnancy, as well as associations between losses of these traits during lactation and subsequent reproductive performance were also developed.
