Karl Loewwnstein's Militant Democracy: In Search of Its Origin"
ドイツ連邦共和国基本法に反映された「戦闘的民主主義」は1933年に米国へ亡命したユダヤ系ドイツ人憲法学者カール・レーベンシュタインにその起源を求めることができる。本稿はレーベンシュタインに、マックス・ウェーバー、ハンス・ケルゼン、カール・シュミットらが与えた影響を明示するとともに、レーベンシュタインの半生をたどり、彼が亡命先の米国で1937年に発表した論文の意義について考察するものである。departmental bulletin pape
Regarding the role of the regional council for measures for children requiring protection during long school vacations: Observations from a fact-finding survey of support during simultaneous school closures due to the spread of COVID-19 infection
本研究の目的は、新型コロナウイルス感染拡大下において、学齢期の子どもの支援において要対協が行なった支援の実態を明確にし、その役割を明らかにすることである。これを通じて、学校の長期休業中の要対協の果たすべき役割について検討した。結果、コロナ禍において要対協は平常時に比べて、「関係機関との連携の工夫」「主体的な状況把握」「学校内の専門職との連携」を重視し調整機能を発揮するよう支援が行われていることなどがわかった。これらを通じて、学校の長期休業中には子どもの状況確認および課題把握に関するニーズがあり、要対協においては子どもの支援に必要な柔軟性を伴うネットワークを形成していく役割があることが明らかとなった。departmental bulletin pape
Research on Vitality and Sustainable Development of Urban Villages from the Urban Perspective
北九州市立大学博士(工学)China's urban development has shifted from rapid urbanization to stock development with urban renewal as the main focus, but the backward facilities and inefficient allocation of public resources in urban villages make it difficult to support sustainable urban development, leading to a decline in the quality of life of residents and dissipation of urban vitality. Urban vitality is an important indicator of healthy and sustainable urban development, and it is of great significance to study the impacts of urban villages on vitality, to re-conceptualize the value of urban villages, and to explore the development path of urban villages for the sustainable development of cities. This study takes urban villages and urban vitality as the research object and proposes a quantifiable and replicable framework for the adaptation of urban villages in Shenzhen. After assessing Shenzhen's vitality in terms of economic, social, and cultural aspects, a regression model is developed to analyze the relationship between vitality and the built environment. Finally, an empirical case study is conducted. It is hoped that this will deepen the community's understanding of urban villages and provide a theoretical basis for the long-term revitalization and sustainable development of cities.doctoral thesi
Study on the influence of indoor environment on perceived comfort in elderly care buildings
北九州市立大学博士(工学)The paper takes a human-centered approach and aims to achieve perceived comfort. It applies physiological sensing technology and eye tracking technology to the study of perception-environment and quantifies the unobservable variable of perceived comfort through human factors technology. By analyzing the physiological indicators of different perceptual states obtained through measurements, and synchronously verifying the representativeness of the changes in various physiological indicators through subjective questionnaires, comfort states are determined, and corresponding spatial indicators and parameters are derived. Through experiments conducted in residential and restaurant spaces, one-way perceived comfort, room brightness under single functional behavior, spatial distance, appropriate sound pressure levels, comfortable temperature, humidity, and the use of warm and safe decorative materials are obtained as spatial indicators and features.doctoral thesi
Study on Hematite Photoanodes for Photoelectrochemical Water Splitting
北九州市立大学博士(工学)Hematite (α-Fe2O3) is a potential photoanode candidate for PEC water splitting owing to its inexpensive, high abundance in nature, and suitable band gap (~2.1 eV) under visible light irradiation. However, Fe2O3 still suffers from low PEC efficiency, mainly due to poor electrical conductivity and limited light absorption. This thesis proposes methods for developing hematite photoanodes with improved PEC performance for water splitting. Additional annealing in an argon atmosphere improves the PEC properties by simultaneously increasing donor density and electrical conductivity. Furthermore, 3D macroporous conductive substrates enable higher loading and thinner thickness of the hematite layer, resulting in enhanced PEC efficiency. Additionally, the AEM-PEC system achieves water splitting in pure water without supporting electrolytes, overcoming mass-transport limitations through the synergistic combination of porous photoanodes and solid electrolyte membranes. This low-cost and straightforward device integration of porous hematite photoanodes with AEM exhibits promising potential for advancing sustainable energy production through PEC applications.doctoral thesi
Study on the thermal performance of lightweight wall using Phase-Change Material
北九州市立大学博士(工学)Phase-change materials (PCM) can improve the thermal performance of lightweight walls, but their contribution efficiency is related to the PCM thermo-physical parameters, installation locations, and climatic conditions. However, the current research mostly focuses on a specific factor, which makes the existing conclusions too absolute and flawed. Therefore, the typical lightweight wall was taken as the research object in this paper, ascertained the basic scientific problem of the influence laws and suitability of different PCM parameters on the thermal performance of lightweight walls under different thermal boundaries through theoretical analysis, numerical simulation, and experiment. Meanwhile, evaluated the energy-saving potential of PCM lightweight wall and its economic feasibility in different climates/cities. The research results can provide a reference for decision-makers to select suitable PCM products in lightweight walls in terms of energy-saving and economics, and provide data support for manufacturers to develop innovative energy-saving lightweight wall products using PCM.doctoral thesi

Research on building envelope for energy conservation by corncob materials in Qingdao Liyuan buildings
北九州市立大学博士(工学)This study investigated and optimized the energy-saving and indoor environmental conditions of Liyuan houses in Qingdao, China, with a trial of corncob material. Through literature review, in-field survey and experimental simulation, both of the energy saving characteristics and the indoor thermal environment of Liyuan houses were analyzed. The renovation methods of buildings for energy-saving and indoor environmental comfort improvement were carried out. It proved the insulation renovation could effectively improve building energy performance and indoor comfort. Meanwhile, agricultural wastes are treated as alternative supplement with consideration of realistic shortage of natural resource. Corncobs and construction wastes are co-processed to prepare recycled aggregate composite ecological concrete. With comparative analysis of the results, it discussed the feasibility of the corncob material as an energy-saving material. In conclusion, the envelope renovation with application of ecological concrete could improve the indoor environment with longer comfort time and reduce energy consumption.doctoral thesi
