本研究では，兵庫県の病院を対象に，病院敷地内外の緑地の構成とリハビリの利用状況およびその効果に対する認識について明らかにした。アンケートの結果109 病院のうち86.3%に緑地が存在し，そのうち87.2%が理学療法を中心としたリハビリに利用しており，複数種類の敷地内緑地や隣接緑地で行うリハビリに対する精神的・身体的効果の有効性が示唆された。また，GIS と航空写真を用い，リハビリの利用状況および効果に対する認識と人口集中地区および緑地の構成の関係を調べた結果，隣接緑地を利用する病院の多くが都市部に立地し，緑地の個数と面積がリハビリの利用に影響を与えている可能性が示唆された。

<p>In order to clarify the issues on succession of the traditional events, we investigated the places where the traditional events are held, the relation to the traditional events of the local residents, and resident consciousness of the future way in Ibusuki city, Kagoshima prefecture. The results show that most of the festivals of the "Kado" such as Moidon and Uchigami were held at the private lands, and most of the traditional events on village or elementary school district such as Onibitaki and Rokugatsudo were held at the community centers or the common open spaces of the village communities. It is suggested that the local residents lack the sense of belonging to the "Kado", therefore the festivals of Moidon and Uchigami have become difficult to continue. It is necessary for the festivals of the "Kado" to expand the management unit to the village, and to reconsider the places of implementation. On the other hand, Onibitaki and Rokugatsudo were found to be events for all generations to participate. However, it became clear that the younger generation had a tendency to feel the problems against the future implementation of these two kinds of events.</p>

本研究では，小規模集落化した旧鉱山まちである兵庫県養父市大屋町明延区を対象に，景観の継承課題を明らかとした。まず，まちの最盛期における建物配置と景観形成要素の残存状況により，歴史ある村の街並みや，川沿いにはり付く住宅群，鉱山社宅群などが継承された景観として重要であることが示された。次に景観資源に対するアンケートの結果，居住者と地域外の主体では，鉱山施設や街並みを残したい重要度の認識に差が生じたことが示された。さらに，空き家の分布調査より街並みや社宅群が危機的な状況といえ，地区ごとの特性に応じた活用方策が考察された。

<p>Since middle ages Ryukyu Kingdom, Amami Oshima have long had faith in such an indigenous folk religion as Noro. This religion maintained sanctuaries such as Kamiyama (a holy mountain) and Kamimichi (a clean way), miya (a central plaza), toneya (a religious hut). However, Noro faces the crisis of the extinction as a result that a religious system changed under the influence of the modernization. Therefore, we investigated the succession of Noro religion in each village and relationship with ritual spaces from interview to regional inhabitant. As results, it was clarified that the village events as "the respect for the elderly festival" and Noro religion such as "the harvest festival" were gathered, to reduce the burden on local resident and to invite gallery. Moreover, it was confirmed that miya and toneya were not only easy to maintain but also utilized. On the other hand, kamiyama was maintained but is not used. Moreover, kamimichi was just before disappearance without being used.</p>

<p>"Moidon" is a forest of the old folk belief to be left on Satsuma and Osumi Peninsula in Kagoshima, and it is enshrined as the standpoint of the community. Moidon tends to disappear in recent years, it is necessary to consider the effect of a public measure such as cultural property and the necessity of other conservation system. In order to clarify the effects of designation of cultural property and issues to inherit Moidon, we investigated the transition of spatial composition, flora, events such as the festival, and management of the Moidon, and resident consciousness against the Moidon designated the cultural property of Ibusuki City. The results show that the subsidy from the city works effectively in management of the Moidon, and the designation contributes to the recognition of residents to the Moidon. It is suggested that consolidation and simplification of festivals related to the Moidon is advanced, and continuance of the festival and management has been difficult. It is necessary to spread understanding and to enlarge participants of Moidon.</p>

<p>It is important to analyze streetscape because the street becomes the place where the pedestrian experience townscape. In this study, we investigated how to see landscape resources on typical streets by focusing on sequential landscape in the old castle town in Sanda City, Hyogo. We took pictures of the streetscape every 15m, and grasped having landscape resources or not in the photograph. Based on this result, we extracted typical scene landscapes on the streets, and specified 13 important areas where landscape resources are seen characteristically by analysis of sequentiality of scene landscape and road shape. In important areas, road shape such as a curve or a slope affected how to see landscape resources, and created characteristic sequential landscape. It is suggested that extracting of important areas enables showing the place where should be worked on landscape planning as priority, and the basis of guidelines for landscape planning of old castle town.</p>

<p>In this study, we investigated the relation between a distribution of landscape resources and the residents' recognition in the old castle town in Sanda City, Hyogo. We divided a study area with 3 areas; old residential area, merchant's houses area and teramachi area by the land use of the early modern times and current. And we picked up 295 landscape resources by the field survey. At the result, there was difference in the distribution of green spaces and historical buildings between 3 areas. At the results of the questionnaire survey to residents while they strolling through the town and taking a workshop for the landscape of the study area, there were 124 recognition points. And 46% of recognition points didn't correspond to landscape resources. In addition, there were difference in the recognition types between 6 spots where recognition points were concentrated, such as the nostalgic type appeared in the park and water-way and the symbolic types appeared in the street with historic buildings. These results suggested that the importance of considering the landscape planning for 6 model spots of 3 areas in the old castle town.</p>

<p>"Moidon" is a sacred place of the old folk belief to be left on Satsuma and Osumi Peninsula in Kagoshima, or a deity enshrined at the sacred place. Moidon is not only a large forest, but also a big tree or a small bush, and usually does not have shrine buildings. Moidon is considered an invaluable asset because it leaves the origin of the Japanese Shinto shrine in now. In this study, we investigated location, continuation situation, the spatial morphology, spatial transformation, relation of local residents, having folklore or not, and management system of some Moidon around Kinko-cho, Kagoshima prefecture. The results shows that Moidon tends to disappear, reduce or be moved in recent years for some kind of development such as agricultural field improvement. On the other hand, in some Moidon, development has been avoided by the curse of Moidon. The relation to local residents such as the festival, offering, and cleaning tends to decrease. It is suggested that Moidon is located in the place where is important to the community spatially. It is necessary to regenerate Moidon as the standpoint of the community by addition of public support.</p>

Many citizen's demands on roadside trees make unplanned prunes and a change for the worse landscape. In this study we analyzed a citizen's demands on maintaining roadside trees in Higashiosaka City. To use a method of analysis on administrative operations, we utilize a text data of citizen's demands on maintaining roadside trees that Higashiosaka City government has, and use simple text mining tool. As a result of analysis, we have showed that text mining tool can grasp relations between various citizen's demands visually, and extracted important words and clusters. And as a result of classification of administrative responses, we have confirmed a germinations of public-private partnership and potentials of reflection to maintenance plan of roadside trees. From the above results, we examined that 1) text mining valid for grasping the citizen's demands of roadside trees, 2) the department of maintaining roadside tree must have a mid and long-term maintenance plan and authorized role-sharing with residents.

本研究では，兵庫県佐用町の13の協議会を対象に，協議会による地域自治の段階性について研究した。各協議会の地域自治の段階を，計画書に記載された事業と活動実態における実施事業から明らかとした。その結果，計画書に比べて活動実態では，地域自治の段階に協議会間で顕著な差がみられた。また，各協議会のセンター長へのヒアリング調査の結果，一律の組織設立に地域が適応できなかったことや，支援体制がうまく機能していなかったことなどにより，協議会間の差が生じた可能性が考えられ，各協議会が目指すべき方向性や，各段階に応じた支援のあり方について考察がなされた。

In this study, we investigated the residents' participation in a festival and the community consciousness of residents in the area where the residents' organization was divided by the urbanization. The study area was the region of the old Tenma village in Otsu-ku, Himeji-shi, Hyougo-ken. And the festival which we investigated was an autumn festival of the Usukihachiman Shrine. We comprehended the changes in the residents' organization and the management of the festival by interview survey to the residents and follow-up survey of a festival float. As a result, the study area was divided into 5 districts based on each property. And according to the results of questionnaire survey to each district, the residents living at the old village were managing the festival according to the old custom. And they were building a close community compared with other residents. On the other hand, the households which only view the festival had a stronger attachment to the local area than the households without participation in the festival. In order to utilize the festival to reconstruct a local community, it is necessary to create opportunities and places for participation in the festival in districts other than the old village.

本研究は，大阪湾東岸域の砂浜に生息するウミホタルを対象とし，飼育試験と現地調査からHSI （生息地適性指数）モデルを構築することを目的とした。塩分濃度が0.5～3.0%の6 段階の試験区を設定した飼育試験の結果，半数影響濃度（EC50）が1.57%と算出された。また，溶存酸素量が1.0～6.0mg/L 以上の6 段階の試験区を設定した飼育試験の結果，半数影響量（ED50）が3.70mg/L と算出された。さらに，大阪府南部における調査データを回帰樹木により解析した結果，含泥率の不適値が1.280%以上であることが求められた。これらの結果をもとに構築されたウミホタルのHSI モデルは，大阪湾東岸域の砂浜におけるウミホタルの個体数を73.2%予測できることが示された。

わが国を代表する伝統的林業の一つである吉野林業は,極端な密植と弱度の間伐を数多く繰り返して長伐期とする施業によって,年輪幅が密で均一で,強度に優れた高級材の産地として発展してきた。これは優れた育林技術の結果であり,それを支えてきたのが吉野林業の特徴である山守制度である。本研究では,吉野林業において,山守が森林の管理状態に及ぼす影響を明らかにするとともに,山守の存続のあり方について考察することを目的とする。49林分の調査結果より,吉野林業においては,山守は森林の管理状態に影響を及ぼしているが,一部の管理業務しか実施されていない林分も多く,十分な機能を発揮しているとは言えず,その維持も困難な状況にある。山守の存続に資する新たなシステムとは,見回りの有償化,新たな取引システムへの見直し,山守と中小規模所有者をつなぐネットワークの形成,広範囲に後継者を募り,村域単位で育成するシステムの構築などである。

In this study, we identified bottom environments suitable for habitation by Vargula hilgendorfii, or the sea-firefly, and the relationship between their habitats and the construction and maintenance of the sandy beach. The study areas included 7 observation lines at 5 sandy beaches in southern Osaka. The construction was assessed by the origin of sands and construction of artificial structures, and maintenance was assessed by leveling of sands and replenishment of sand. Bottom environments and the number of V. hilgendorfii were assessed using a Smith-McIntyre grab sampler. Statistical analysis of a classification and regression trees found the following suitable conditions for V. hilgendorfii inhabitation; oxidation-reduction potential of more than -5.5mV and sorting coefficient of less than 0.646. In addition, statistical analysis of a generalized linear model found habitats of V. hilgendorfii were created in the following places; places where without an artificial structure, places where water depth was shallow due to replenishment of sand. On the other hand, places where the bottom sediment was deoxidized due to offshore breakwaters and jetties hindering tidal currents were unsuitable for V. hilgendorfii. These results suggested that the difference of the construction and maintenance of the sandy beach influenced on the habitats of V. hilgendorfii.

In this study, we identified bottom environments suitable for habitation by Vargula hilgendorfii, or the sea-firefly, whose habitat is the sea floor in shallow water, and environmental conditions which may affect habitation. The study areas included 70 points at 17 sandy areas off the eastern coast of Osaka Bay, where environmental degradation has been a concern. The quality of water and sediment on the sea floor was assessed, and the number of sea-fireflies inhabiting the locations was evaluated using bait-traps. The results showed that no or only a few sea-fireflies survive in the following places; places where salinity and dissolved oxygen were reduced due to nearby rivers, places where the bottom sediment was deoxidized due to artificial structures hindering tidal currents, and places where there was an accumulation of fine sand due to its drifting along rapid currents. The majority of the sea-fireflies live at limited locations in the center of Osaka Bay. Statistical analysis of a generalized linear model found the following conditions necessary for sea-firefly inhabitation; dissolved oxygen (explained deviance; 27.2%), oxidation-reduction potential (18.3%), salinity (12.8%), and mud content (7.3%).
