Exploring the Functions of Geriatric Psychiatric Day Care Center under the Local Aging Policy: A Need Theory Perspective
No full textFollowing the trend of the aging of the world's population structure, Taiwan is expected to enter a super-aged society in 2025 (over 20% of the population aged 65 and over); Phenomena that accompany aging, such as increased chronic disease, increased risk of disability and dementia, increased demand for care workers, decreased labor force, increased family care burden, are not only personal but social issues.
In line with the development of the government's long-term care policy, the current long-term care-related business is booming, and with the change of people's thinking, the way of care is also changed. How to implement the local aging is the long-term direction of the current long-term care policy.
The author of this paper, as the leader of the day-care center, hope to explore the motivations and needs of individual cases and their families to participate in the day-care center based on the theory of needs, and then providing a reference for the development of the day-care center in the future.
The research conclusions are divided into four major points, which are used as a reference for future research.
1. The motivation for participating in day-care center is mostly the arrangement of family members, and the needs of family members can be considered in multiple aspects.
2. In addition to providing basic care needs, the day-care center also needs psychological counseling and support capabilities for cases and their families, which can generate a positive care cycle.
3. The working team of the day-care center needs to have three basic abilities: (1) Professional care skills, (2) Spiritual counseling skills, (3) Ability to design living arrangements.
4. The day-care center has to enter the community and create the living structure of the local elderly, so that the day-care center can truly become a community and reduce the institutional sense of the day-care center and the loneliness of aging
Tribological interaction between one dimensional nano material and semi-conductor surface
No full text本文主要針對一維奈米材料與半導體表面之間的摩擦與吸附性質來做研究與討論，一維奈米材料將被放置在原子力顯微鏡中，利用原子力顯微鏡側向操控的特性，進而找出奈米管與半導體表面之間的摩擦吸附性，不但在設計奈米元件上有所助益，甚至可應用到能量儲存的元件上。本實驗將採用多層奈米碳管和氮化硼奈米管為實驗對象，並使用矽和二氧化矽做為半導體的基材，經側向操控後，奈米管於半導體表面上滑移轉動，而奈米材料與半導體之間的摩擦吸附性質將在文中一一討論。
第一利用原子力顯微鏡研究多層奈米碳管與二氧化矽的摩擦吸附性質。利用原子力顯微鏡的側向操控的特性，可觀察到多層奈米碳管於二氧化矽上滑移轉動，同步取得側向力曲線的變化，再經由整理之後，得知兩者之間的吸附力，再根據多層奈米碳管與二氧化矽的接觸面積，即可計算出多層奈米碳管與二氧化矽之間的剪應力，大約是60 MPa。再依據實驗結果，可發現剪應力與多層奈米碳管轉動角度是線性相關，我們也將在文中歸納出施力點與轉動支點的關係，再針對多層奈米碳管的轉動現象與吸附性逐步探討。
第二接著探討氮化硼奈米管與矽晶片的摩擦吸附性。同樣利用原子力顯微鏡的側向操控功能，也可以在實驗的過程中，也可觀察出氮化硼奈米管於矽的表面上滑移轉動情形後，藉由所得的側向力曲線得知，得知兩者之間的吸附力，再配合修正之後的接觸面積，與滑移轉動的面積，可以計算出氮化硼奈米管與矽晶片之間的剪應力與比滑移能量損耗，大約是0.5 GPa與0.2 J/m2，然後再與其他相關文獻比較之後，結果發現氮化硼奈米管吸附能力比較好，因此氮化硼奈米管非常適合運用於儲氫元件上。
最後本研究的結果驗證原子力顯微鏡可以拿來操控奈米材料，而且能精準的定位奈米材料的位置，對於研究奈米科技可以提高準確度，另外期望MWCNT與BNNT的研究結果，可以作為日後設計奈米元件的依據。The target of this dissertation is the tribological interaction between one dimension nano material and semi-conductor surface. One dimension nano materials are manipulated in an atomic force microscope (AFM), and tribological properties of nanotube-surface are discovered. So we can use the information of the tribological properties of nanotube-surface to design nano devices or energy storage. In our experiments, we adopted the multi-walled carbon nanotubes (MWCNTs) and boron nitride nanotubes (BNNT) to be one dimension nano material. Silica and silicon which properties both are semi-conductor are used as substrate materials. Therefore, we discussed the tribological interaction between one dimension nano material and semi-conductor surface in detail.
The tribological interaction between MWCNTs and silica surface using lateral manipulation in the AFM. The MWCNT is mechanically manipulated by a pyramidal silicon probe of an AFM using the same scan mechanism as in the imaging mode. With a controlled normal force of the AFM probe, it was found that lateral force applied to the MWCNT could overcome the tribological adhesion between MWCNT and silica surface, causing individual MWCNT to rotate on the silica. According to the results, the shear stresses due to tribological interacting with the MWCNTs and the silica are 59.6 MPa and 64.8 MPa for the MWCNT 1 (100 nm diameter) and the MWCNT 2 (60 nm diameter), respectively. Experimental results show that the shear stress increases with the increasing rotation angle for each manipulation, from which we determine the linear fitting function. In addition, we determine the relationship between push point and pivot point to realize the rotation behavior. The implications of tribological interaction between the MWCNTs and silica surface are discussed in detail.
The tribological interaction between BNNTs and silicon was studied with lateral manipulation in AFM. The BNNTs was mechanically manipulated by the lateral force of an AFM pyramidal silicon probe using the scan mechanism in the imaging mode. With a controlled normal force of the AFM probe and the lateral motion, the lateral force applied to the BNNTs could overcome the tribological interaction between BNNTs and silicon surface. The individual BNNT is forced to slide and rotate on the silicon surface. Based on the recorded force curve, the calculated shear stress due to surface adhesion is 0.5 GPa. And the specific sliding energy loss is 0.2 J/m2. Comparing BNNTs and CNTs [24], the shear stress and specific sliding energy loss of BNNTs are an order of magnitude larger than that of CNTs. Therefore, the results show that the tribological interaction between BNNTs and silicon surface is higher than that of CNTs
Interconnection networks for parallel and distributed computing
Full text linkParallel computers are generally either shared-memory machines or distributed- memory machines. There are currently technological limitations on shared-memory architectures and so parallel computers utilizing a large number of processors tend tube distributed-memory machines. We are concerned solely with distributed-memory multiprocessors. In such machines, the dominant factor inhibiting faster global computations is inter-processor communication. Communication is dependent upon the topology of the interconnection network, the routing mechanism, the flow control policy, and the method of switching. We are concerned with issues relating to the topology of the interconnection network. The choice of how we connect processors in a distributed-memory multiprocessor is a fundamental design decision. There are numerous, often conflicting, considerations to bear in mind. However, there does not exist an interconnection network that is optimal on all counts and trade-offs have to be made. A multitude of interconnection networks have been proposed with each of these networks having some good (topological) properties and some not so good. Existing noteworthy networks include trees, fat-trees, meshes, cube-connected cycles, butterflies, Möbius cubes, hypercubes, augmented cubes, k-ary n-cubes, twisted cubes, n-star graphs, (n, k)-star graphs, alternating group graphs, de Bruijn networks, and bubble-sort graphs, to name but a few. We will mainly focus on k-ary n-cubes and (n, k)-star graphs in this thesis. Meanwhile, we propose a new interconnection network called augmented k-ary n- cubes. The following results are given in the thesis.1. Let k ≥ 4 be even and let n ≥ 2. Consider a faulty k-ary n-cube Q(^k_n) in which the number of node faults f(_n) and the number of link faults f(_e) are such that f(_n) + f(_e) ≤ 2n - 2. We prove that given any two healthy nodes s and e of Q(^k_n), there is a path from s to e of length at least k(^n) - 2f(_n) - 1 (resp. k(^n) - 2f(_n) - 2) if the nodes s and e have different (resp. the same) parities (the parity of a node Q(^k_n) in is the sum modulo 2 of the elements in the n-tuple over 0, 1, ∙∙∙ , k - 1 representing the node). Our result is optimal in the sense that there are pairs of nodes and fault configurations for which these bounds cannot be improved, and it answers questions recently posed by Yang, Tan and Hsu, and by Fu. Furthermore, we extend known results, obtained by Kim and Park, for the case when n = 2.2. We give precise solutions to problems posed by Wang, An, Pan, Wang and Qu and by Hsieh, Lin and Huang. In particular, we show that Q(^k_n) is bi-panconnected and edge-bipancyclic, when k ≥ 3 and n ≥ 2, and we also show that when k is odd, Q(^k_n) is m-panconnected, for m = (^n(k - 1) + 2k - 6’ / ‘_2), and (k -1) pancyclic (these bounds are optimal). We introduce a path-shortening technique, called progressive shortening, and strengthen existing results, showing that when paths are formed using progressive shortening then these paths can be efficiently constructed and used to solve a problem relating to the distributed simulation of linear arrays and cycles in a parallel machine whose interconnection network is Q(^k_n) even in the presence of a faulty processor.3. We define an interconnection network AQ(^k_n) which we call the augmented k-ary n-cube by extending a k-ary n-cube in a manner analogous to the existing extension of an n-dimensional hypercube to an n-dimensional augmented cube. We prove that the augmented k-ary n-cube Q(^k_n) has a number of attractive properties (in the context of parallel computing). For example, we show that the augmented k-ary n-cube Q(^k_n) - is a Cayley graph (and so is vertex-symmetric); has connectivity 4n - 2, and is such that we can build a set of 4n - 2 mutually disjoint paths joining any two distinct vertices so that the path of maximal length has length at most max{{n- l)k- (n-2), k + 7}; has diameter [(^k) / (_3)] + [(^k - 1) /( _3)], when n = 2; and has diameter at most (^k) / (_4) (n+ 1), for n ≥ 3 and k even, and at most [(^k)/ (_4) (n + 1) + (^n) / (_4), for n ^, for n ≥ 3 and k odd.4. We present an algorithm which given a source node and a set of n - 1 target nodes in the (n, k)-star graph S(_n,k) where all nodes are distinct, builds a collection of n - 1 node-disjoint paths, one from each target node to the source. The collection of paths output from the algorithm is such that each path has length at most 6k - 7, and the algorithm has time complexity O(k(^3)n(^4))
Globalization, land expropriation, and community resistance: a case study in Wanbao community, Miaoli County, Taiwan
Full text linkThe Land Expropriation Act of Taiwan, enacted in the year 2000, has been abused by the local authorities without proper oversight from the public, and this abuse has often caused displacements without reasonable compensation. The abuse of land expropriation can be devastating to those who live in the rural areas of Taiwan, where agricultural land for development is abundant and farmers are the culturally disadvantaged group of the society. This research specifically focuses on the land expropriation experience of Wanbao Community, a rural farming community located in the middle-west part of Taiwan that has successfully resisted land expropriation through a grassroots movement. This paper strives to offer the following: a comprehensive understanding of the legitimization of land expropriation from the local as well as the global perspective; background information on the rise of land expropriation in Taiwan; and the effects of such processes on farmers’ social status. Moreover, based on field research in Wanbao Community, this thesis analyzes the keys to successful resistance to land expropriation and discusses possible planning solutions to prevent it.
Research shows that arbitrary land expropriation in Taiwan can be propelled by the state’s pursuit of current trends in global capitalism, also known as globalization, and the urban citizens’ pursuit of a modern lifestyle. Along with the normalization of what Agamben (2005) calls “the state of exception” and Sassen (2014) refers to as processes of “expulsion,” the extreme top-down strategy that deprives citizens of their private property without proper compensation becomes a fast and easy way for governments at all levels to acquire land. This brutal planning process is legitimized by the authorities through the Land Expropriation Act, embedded in the mainstream planning structure. Among citizens, however, the value of land is defined differently, according to different life experiences. To the elites and the authorities, farmlands are seen as underdeveloped, with potential to be “upgraded” for more economically profitable use. To farmers in Wanbao Community, land is viewed as a livelihood instead of a commodity that can be measured by a monetary system. The mainstream planning system, however, does not appreciate the latter value when land expropriation decisions are made; nor does it provide formal space of communication for farmers to express and participate in the decision-making process. Contrary to the pro-appropriation discourse of authorities, which seeks to discredit communities’ resistance to the state’s land expropriation policies by calling it emotional and irrational, this research drawing on the experience of Wanbao Community, suggests that farmers’ resistance to development is in fact reasonable and carefully planned and organized. Interviews with the members of government planning agencies as well as detailed account of the farmers’ successful mobilization in Wanbao Community offer evidence that citizens’ insurgent planning practices can be a possible solution to government’s unjust land expropriation policies in Taiwan.Submission original under an indefinite embargo labeled 'Open Access'.

Apophatic Elements in the Theory and Practice of Psychoanalysis: Pseudo-Dionysius and C.G. Jung
No full textThis thesis identifies apophatic elements in the theory and practice of psychoanalysis through an examination of Pseudo-Dionysius and C.G. Jung. Pseudo-Dionysius brought together Greek and Biblical currents of negative theology and the via negativa. The apophatic concepts and metaphors which appear in the work of Pseudo-Dionysius are identified. The psychology of Jung can be read as a continuation and extension of the apophatic tradition. The presence of neoplatonic themes in Jung’s work is discussed, as well as his references to Pseudo-Dionysius. There is a thorough examination of Jung’s discussion of opposites, including his reception of Nicholas of Cusa’s concept of the coincidence of opposites. The role of the transcendent function in Jung’s psychology is reviewed. The work of contemporary scholars of religion, philosophers and Jungian theorists are compared to Jung’s using the lens of apophasis. There is an exploration of ways in which motifs in Pseudo-Dionysius’ Ecclesiatical Hierarchy resonate with contemporary psychoanalytic psychotherapy. This study demonstrates that apophatic motifs saturate Jung’s work. It provides a platform for research into apophasis in the wider field of psychoanalysis
