利用滲透試驗探討雙層土壤之滲流沖蝕行為及其數值模擬

Seepage erosion occurs when finer particles are dragged out from other soil particles by water. This type of erosion causes progressive failure inward into the slopes and slope instabilities. Therefore, it is necessary to explore the behavior of seepage erosion in order to prevent such failure in slopes. According to results of field investigations, we do seepage erosion experiments in a laboratory to understand the erosion behavior. After that, we utilize FEM soft-ware – FLAC5.0 in order to determine the feasibility of numerical analysis in simulating seepage erosion behavior.滲流沖蝕係指土壤中的細顆粒因地下水流驅動通過較大顆粒間之孔隙，被帶離坡面後，會由坡面向坡體內部發展出漸進式破壞，進而引發邊坡問題，故對邊坡滲流沖蝕行為的瞭解有其必要性。因此，本研究根據現地調查結果，於室內利用滲透試驗儀器進行滲流沖蝕試驗，以了解不同情形下各試體之沖蝕行為。而後，為了解數值軟體用於模擬滲流沖蝕行為之可行性，故嘗試採用有限差分法軟體－FLAC5.0 進行模擬，以期能作為未來用於滲流沖蝕模擬之參考

Establishment of the Watershed Image Classified Rule-Set and Feasibility Assessment of Its Application

Extreme weather disasters are widely distributed. Moreover, the mutual relations between such disasters can easily make them even more extensive. Rapidly obtained satellite images of vast areas can be effective in helping to develop disaster prevention strategies. This study established a watershed satellite image classification rule-set by using the object-based image analysis methodology. Several surface features in the watershed image were been classified, including main channels, secondary channels, sandbars, alluvial fans, landslides and place of the geotechnical damage. This study practically applied this rule-set in different watersheds and different-resolution satellite image. Also assessed the feasibility of the rule-set by comparing with the investigation photos and statistical analysis. The results show that the rule-set logic can be applied flexibly in different watersheds and different images. The classification of the rule-set is reproducible and accurate. As this result, we can apply the rule-set to disaster management and the land use planning in the future work.極端氣候下的災害事件分布廣泛，且相互影響之關聯性易使災害規模擴大，藉由衛星 影像判釋具廣域且快速的特色能夠有效協助研擬防災策略。本研究建立一套流域衛星影像分類 之規則集，當中引入物件式影像分析方法，使分類流程依據人工判釋之經驗與知識，針對流域 影像分類出周邊河川地形單元、崩塌地以及地工災害的位置。實際應用此規則集於不同流域以 及不同解析度之衛星影像，透過比對現地勘查資料和計算誤差矩陣來評估其邏輯之可行程度。 結果顯示，本研究所建立之規則集邏輯泛用於不同流域、不同影像，且任何使用者之操作經過 適當的調整皆具有重現性及相當的判釋精度，提供災害管理、土地利用之深入探討一項工具

The influence of knowledge management on adoption intention of electric vehicles: perspective on technological knowledge

Purpose: Technological innovation is one of the remarkable characteristics of electric vehicles (EVs). This study aims to analyze how consumers' technological knowledge affects their intention to adopt EVs. Design/methodology/approach: Original data were collected via a survey of 443 participants in China. An extended technology acceptance model was constructed to identify the factors influencing consumers' intention to adopt EVs and related technological knowledge pathways. Findings: The results show that consumer technological knowledge is positively and significantly related to EVs' perceived usefulness, perceived ease of use, perceived fun to use and consumers' intention to adopt EVs. In addition, no direct and significant relationship is found between perceived fun to use and willingness to adopt EVs, from the technical knowledge dimension. Practical implications: Imparting consumers with EV technological knowledge and usefulness may be an effective way to enhance their awareness and willingness to use EVs. Moreover, the role of females in the decision to adopt EVs should not be ignored, especially in decisions to purchase a family car. Originality/value: Prior studies lack a technological knowledge-based view, and few studies have discussed how to explore the effects of consumer technological knowledge about EVs on their adoption intention. This study fills the research gap

台2線 68K 八斗子滾石災害致災成因初探

基隆市北寧路於2013 年8 月31 日下午發生高強度降雨事件 (最高達94.5 mm/hr)，並導致台2 線68K+000 處於當日16 時19 分左右發生落石擊毀小客車之意外。本次落石災害之發生區屬於大寮層中段塊狀砂岩，且為逆向坡之型態，現地調查結果顯示本區域具有兩組傾角近乎垂直之節理面，一組走向約略平行於海岸線，另一組走向則約略垂直於海岸線。致災成因可能與長期雨水入滲及風化作用有關，節理裂隙除因風化作用逐漸加大外，節理面上之含鐵質結核亦可能於風化後體積增加，進而加速節理開裂速度。本次落石災害之運動歷程大致可分為傾倒、滾動、墜落、彈跳、滾動等數段歷程，落石運動過程耗時約23 秒，移動路徑上之植被與風化土壤層可能為遲滯落石運動之主因。本文將說明此次災害之地質調查成果，並探討可能之破壞機制，以供未來類似災害之防治對策參考。Several rockfalls caused damages on Highway No.2 during an intensive rainfall on August 31, 2013, in Keelung. One of the rockfalls hit a car and the event was captured by a camera. This study analyzes the mechanism of the rockfall based on the video and field investigation. Two major joints which led to the hazard, one was parallel to the coast and the other was perpendicular to the coast. Both of them were almost vertical and cut the rock into several blocks. Weathering processes may have lead to the extension of joints during the heavy rainfall; the infiltration and the surface runoff took the weathered material away, making the rock unable and ultimately leading to the rockfall. The process of this hazard can be divided into topple, roll, fall, bounce and roll. The rockfall took about 23 seconds in total. This paper focuses on the results of field investigation and the mechanism of the rockfall is also discussed

Assessing Sustainable Consumption in Packaged Food in Indonesia: Corporate Communication Drives Consumer Perception and Behavior

Sustainable consumption has been addressed in the literature in recent years, especially in relation to changing from a traditional consumption to sustainable consumption. Reducing environmental impacts from waste generation has been the focal point of sustainable consumption. However, a large number of attributes has caused a complexity in understanding which attributes effectively enhance the consumption. In particular, sustainable consumption has been facing a negative trend due to low levels of knowledge about packaging’s environmental impact, failed communication which leads to misperception and irresponsible behavior. This study contributes to proposing a set of attributes for enhancing sustainable consumption in the Indonesian food industry, to fulfill the lack of understanding of the attribute interrelationships using qualitative information. This study proposes a set of attributes to enhance sustainable consumption with qualitative information by assessing the interrelationships among the attributes employing the Delphi method and fuzzy decision-making trial and evaluation laboratory method to provide causal and effect relationships. As a result, corporate communication, consumer perception, consumer behavior, and product packaging are major aspects for sustainable consumption enhancement. Corporate communication becomes a major driver to affect perception and behavior. This study proposes a managerial insight for the packaged food industry on improving several criteria including green marketing, green consumerism, verbal features, and importance of information

Profit Maximization for Waste Furniture Recycled in Taiwan Using Cradle-to-Cradle Production Programming

This study proposes the use of cradle-to-cradle production programming for waste furniture and aims to achieve optimal efficiency by reusing waste furniture and maximizing the corresponding benefits so that the furniture industry is in line with cradle-to-cradle manufacturing. This study is increasingly important to manage products through a comprehensive green reverse logistics system that consists of three procedures, i.e., recycling, reuse, and remanufacturing of waste items. This study proposes a mathematical formula to establish a cradle-to-cradle production programming model for waste furniture. The fuzzy set theory is used to define the attributes that reflect production and market demands such as degree of damage, technical feasibility, market demands, environmental protection laws and regulations, and environmental performance. In addition, particle swarm optimization is adopted to ascertain the optimal profit from waste furniture sales. Through situational simulations and analyses, the fuzzy set information from Taiwan, Germany, and China is compared. The result reveals that the qualitative information proposed has a significant impact on the profit of waste furniture reuse. The production model can effectively assist in the production programming of waste furniture, thereby optimizing profit for cradle-to-cradle production planning
