This paper presents a semi-autonomous seeding robot which is based on both electrical and mechanical platforms that perform advance agriculture process. SeedBot composed of four components: drilling mechanism, body of robot, seed container and paving mechanism. Other than those components the sensor system and the control system are also discussed. The aim of this study is designing and building a low-cost robotic system to automate and optimize process during farming especially for personal usage. This study demonstrates that semi-autonomous farming has crucial advantages over conventional farming. In addition to that, SeedBot provides safer, requires less manpower and precise farming than usual methods that we have so far.

Nowadays, the most of waste materials are incinerated and generated the toxic gases in 日本. On the other hand, the Hydrogen gas (H2) has attracted attention as clean energy due to no emissions of toxic gases. In this work, we investigated that the new hydrogen evolution system using waste materials, such as aluminum (Al) foil and lime desiccant, and also investigated their reaction mechanism. The grinded desiccant was added to Erlenmeyer flask containing 300 mL of water. After dissolution the desiccant, the Al foil was added to the solution to begin the reaction. Generated gas was determined by water displacement method. The gas components are identified by gas chromatography. We found that the waste material reaction combined with waste lime desiccant and Al foil could be used for one of the hydrogen evolution system. This reaction is depended on solubility of lime desiccant, thus mean solubility of CaO in water. The Al foil is reacted with the desiccant more than 20 times of reaction stoichiometry. The calcium ion or calcium complex ions are involved with the excess reaction of Al foil.

小腦萎縮症第三型SCA3為體染色體顯性遺傳疾病。已知為CAG三核甘酸重複序列數目過多的動態突變，造成polyQ在腦部神經細胞核內形成包含體，這種蛋白在細胞內長期堆積會導致細胞退化並死亡。此外，在SCA3熱休克蛋白的表現量較低，使蛋白不正常聚集造成細胞大量釋放氧化性刺激，促使細胞走向凋亡。根據先前研究發現低劑量綠茶多酚EGCG (epigallocatechin-3-gallate) 具有抗氧化且選擇性保護神經細胞的功能，避免氧化壓力導致細胞凋亡。此研究以SCA3患者與正常人的淋巴母細胞株來研究，給予EGCG保護來觀察EGCG在患者與正常人的細胞內對H2O2氧化壓力的耐受性差異，進一步探討EGCG對SCA3熱休克蛋白的表現量，同時觀察EGCG是否影響抗凋亡蛋白的表現。

本研究主要針對造成輕微腦震盪 (Mild Traumatic Brian Injury, mTBI) 的現象及其物理量進行研究，以封閉式頭部工程旋轉加速度的撞擊模型 (Closed Head Impact Model of Engineered Rotational Acceleration, CHIMERA) 為基礎，結合目前常用於頭部碰撞量測的腦部受傷標準 (Head Injury Criterion, HIC)，實現一套由加速度感應器和微處理機組成的可穿戴式輕微腦震盪警示系統。本研究利用此警示系統進行舞蹈和刺激性遊樂設施的實測，探討生活中容易被忽視卻對腦部造成傷害之危險動作。而研究中更提出多重衝擊模擬器的實現方法，此模擬器改善CHIMERA僅單次撞擊工程問題，並結合特徵檢測 (Feature Clarification) 及互相關 (Cross-Correlation) 的定性分析，提供更多元且更符合真實情況的資料，以達到輕微腦震盪警示之功用。最後再根據實驗結果提出警訊，以降低在日常生活中輕微腦震盪發生率。

臺灣高速鐵路因差異沉陷而有行車安全的疑慮，每年耗費數千萬來嚴密監測沉陷。因此，我們希望能有一個可靠、簡便、便宜、及時的新測量方法。 本新測量方法利用商務筆記型電腦中的加速度感測器，來記錄列車行進差異沉陷處的電壓變化，透過Quake Catcher Network Live軟體轉換成加速度值，再經過傅立葉轉換以濾除雜訊的影響，而從加速度、速度、位移、時間之間的定義，得到高鐵於該處的沉陷值。 透過全線測量，訊號的可靠性，使我們得到台灣高鐵全台差異沉陷的分佈狀況。而高鐵苗栗麻園坑段的反覆驗證，沉陷值的正確性，也在誤差的合理範圍內。 由此顯示，此新測量法是可行的。尤其相對於傳統的人工測量方法，這個方法更有利於迅速地測量高速鐵路的差異沉陷，作到即時監測、即時預警，防範事故於未然，更可節省大量的人力與物力。

1 Purpose of the Research Nanocrystal thin films exhibit many useful properties, including electrochromicity and superconductivity. When synthesised via Molecular Beam Epitaxy (MBE), selection of substrate, specifically knowledge of crystal orientation, is critical. Reflection High Energy Electron Diffraction (RHEED) is an in situ crystal characterisation method highly compatible with MBE. This study explores a new method of RHEED analysis to determine crystal orientation. 2 Procedure/Theoretical Framework RHEED characterization is the incidence of a beam of high-energy electrons at a low angle with respect to the sample surface. Electrons diffract, and interfere to form patterns on the detector. Traditionally, studies of RHEED analyse one static image as a representation of the surface structure, or observations of RHEED patterns over time. The approach to RHEED analysis in this study exploits changes in RHEED patterns given a rotating substrate. Having specific rotational symmetries along different axes, crystal structures can be differentiated by determining rotational symmetry through RHEED. Electrons scatter upon incidence with crystal planes within the crystal to form Kikuchi lines on the RHEED detector (Fig. 2). The orientation of crystal with respect to incident electron beam affects the Kikuchi line patterns. If the crystal is rotated, crystal planes change orientation, and electrons would diffract from crystal planes in different directions. As such, as the crystal is rotated, the Kikuchi lines move. When the degree of rotation of the crystal corresponds to the rotational symmetry of the crystal (Fig. 1), the Kikuchi lines return to their original position. As crystals with different crystal plane orientations exhibit different orders of symmetries, analyzing the Kikuchi line patterns of the crystal at different degrees of rotation can reveal the rotational symmetry and consequently crystal plane orientation of a crystal. 3 Data/Experimental Testing In order to assess the practical viability of the proposed method, experiments were conducted on SrTiO3 (001), (110), and (111). SrTiO3 exists as a typical perovskite structure (Fig. 3), often used in the synthesis of superconductors via MBE. 3.1 Methodology RHEED images of each sample were taken at 0◦, 60◦, 90◦ and 180◦. Curves were fit to each Kikuchi line observed in the image (Fig. 4). These Kikuchi line approximations are compared by superimposing the curves traced and qualitatively assessing the degree of similarity between the Kikuchi lines of 2 images, to verify the order of symmetry and crystal orientation of the crystal. In the images of the superimposed Kikuchi lines illustrated in Fig. 5, there is similarity between the Kikuchi lines when only when the sample has been rotated by an angle corresponding its degree of symmetry. 4 Conclusions This study offers a method to determine the crystal orientation of thin film through determining the degree of rotational symmetry of the sample, by observation of Kikuchi lines in the RHEED pattern as the sample is rotated. Experimental data was analyzed qualitatively to verify the viability of this theoretical method in practice. This method could be extended to analyze the symmetry of other crystal structures. As it does not require information on the machine settings or usage of complex functions to produce a reliable output, this method is fast and straightforward, opening doors to more streamlined RHEED analysis.

Diarrhoea is an infectious disease that claims many lives (particularly among infants) and is known among many other infectious diseases, to have a relationship with climate. This projects quantifies this relationship by comparing health insurance treatment claims for diarrhoea and anti-diarrheal drug sales data from the private health sector with temperature and rainfall data provided by the South African Weather Service. The data were then analysed and show that incidence is highly seasonal and varies among regions with different seasonal climates. The results show that climate variability can explain 73% of diarrhea incidence variation with rainfall explaining 8% and minimum temperature explain the other 65 %. Preliminary predictions of future monthly percentage increases in incidence were then made for a series of time ranges. This project demonstrates that with predicted climate data one can predict future variations of diarrhoea allowing the health sector to be adequately prepared.

Lymnae stagnalis (pond snail) is emerging as a preferable invertebrate model in understanding neurological mechanisms because of its simple nervous system. A three-cell network mediates behaviours such as aerial respiration and research has shown that small, subtle changes occurring across the network might result in a disruption of natural behaviour (Lukowiak et al. 1995). It is also known that Lymnae features a more developed eye than other molluscs and studies have shown that various wavelengths of light can activate photoreceptors producing distinct electrophysiological responses (Sakakibara et al. 2004). However, no studies have looked beyond the electrophysiological response. The purpose of this project was to determine if coloured light would firstly, elicit a behavioural response as observed in its movement and secondly, affect learning and memory through the operant conditioning of its aerial respiration.
