Journal of Architecture and Planning (Transactions of AIJ) ( 日本建築学会 ) 82 ( 738 ) 2011 - 2018 2017 [Refereed]

&nbsp;This study shows a strong correlation between light variation and psychological influence in the nighttime landscape. The evaluation factors of the impression of the nighttime landscape in Yokocho consist of two elements; liveliness and attraction. And when we see the street from a perspective of the entire space, face, lighting, etc., the diversity of light variations play a pivotal role in creating liveliness and attraction. From this result, further study on light variation with regard to nighttime landscape in Yokocho is needed. The variety of the amount of light and the position of lighting has a positive influence on the element of the liveliness. The same result is also applicable to various lighting modes. The uniform light quantity in a dark space and the various light quantities in a bright space exert positive effects on attraction of Yokocho. The same result also applies to the case of regular form of lighting. The results show the characteristics of the four targeting Yokocho (Fig. 7). In addition, various light fluctuation factors or mutual relations among the elements illustrates the characteristics of Yokocho And from the viewpoint of the element of the variation of light, we have got clues to develop the attractive nighttime landscape in Yokocho (Fig. 8).

A HISTORY OF THE MODERN BUILDINGS ALONG MIDOSUJI BOULEVARD:Between the construction of Midosuji and the beginning of the control about its townscape preservation

TAKAOKA Shinichi, KANA Koichi, SAKUMA Yasutomi

Journal of Architecture and Planning (Transactions of AIJ) ( 日本建築学会 ) 82 ( 735 ) 1337 - 1347 2017 [Refereed]

&nbsp;This paper aims to discusses a history of modern buildings along Midosuji Boulevard in relation to its urban background. Midosuji is the symbol street in Osaka, and regarded very important for revitalization of Osaka City. &nbsp;Midosuji is a national road, about 4 km long and about 44m wide. It's passes through the central area of Osaka from JR Osaka station to Nankai Namba station. Midosuji was planned in the first urban planning of Osaka City in 1920's, and specified as the first grade road in the plan. The construction was started in 1926, and completed in 1937. &nbsp;This paper deals with the about 1km long of 4km of Midosuji, which is regarded to represent the image of Midosuji best. In this area, 50 buildings were built between 1920 and 1970, from the construction of the street to the beginning of the control about its townscape preservation by Osaka City. &nbsp;The history can be divided into 3 periods from the viewpoints of architectural characteristics, number and arrangement of the buildings. &nbsp;1) 1920-1945 &nbsp;In the 1st period, the construction of buildings were limited because of the influence of the war. 12 buildings were built mainly in 2 zones, Yodoyabashi area (north side) and Hommachi area (south side). Yodoyabashi area consists mainly of financial company buildings like bank and insurance companies, designed in the classical style, on the other hand Hommachi area consists of commercial company buildings, designed in popular style like Spanish. Its tendency stems from the history and its characteristic of the land which was developed in the early modern (Toyotomi and Edo) period as Semba town. &nbsp;2) 1945-1955 &nbsp;In the 2nd period which corresponds to the post-war reconstruction, 10 of 12 buildings were built on the east side of Midosuji, and 9 were bank buildings. Many buildings had granite wall, and emphasized vertical line as the transformation from classicism to modernism. The east side arrangement stems from a difference of lots on the blocks. East side lots were easier to acquire than the west, because the west side lots were too subdivided historically to get in a short period. And banks could build their own buildings preceding other types of company by the then government's finance policies. &nbsp;3) 1955-1970 &nbsp;In the 3rd period, 26 buildings were built on all blocks along Midosuji in the high economic growth. They were planned in the full size of the then architectural restriction, growing demand for utilization of the city center. Consequently, Midosuji had possessed the townscape with completed wall line and skyline. By the industrialization of building construction, curtain-wall system appeared on the wall of 8 buildings, on the other hand old construction of tile wall was still used for 10 buildings.

&nbsp;The study aims to identify relationships between urban areas and bridges designed under the First Osaka Urban Planning Projects. First, we classified patterns of design forms on the bridges with a focus on handrail, main post, and lighting. Second, we conducted quantitative analyses with comprehensive consideration of multiple factors and classified types of bridge design into six clusters. Bridges of each cluster were expanded into a city-wide scale and linear scale, and characteristics of design forms on the bridges were different in each cluster. In conclusion, we showed that the characteristic of bridge designs was positioned by the grade of bridge and tendency of design forms on the bridge, and each bridges were developed temporally-spatially.

Regional Regeneration by Business in Rural Community of In-migrants from Urban Areas

TSUTSUI Kazunobu, SAKUMA Yasutomi, KASAMI Kazuo

JOURNAL OF RURAL PLANNING ASSOCIATION ( 農村計画学会 ) 34 ( 1 ) 45 - 50 2015

「田園回帰」という言葉で都市から農山村への移住がクローズアップされてきている。2014年7月にはNPO法人中山間地域フォーラムが「はじまった田園回帰―「市町村消滅論」を批判する―」と題したシンポジウムが開催され，同年9月に設置された「まち・ひと・しごと創生本部」の基本方針においても「魅力あふれる地方を創生し，地方への人の流れをつくる」とうたわれるなど，都市から農山村への移住が重要な政策的トピックとなっている。新聞においても都市から農山村への移住に関する記事が2013年から急増している。2015年1月から3月までの3か月間だけで前年の半数に達するほどの記事が掲載されており，その関心が社会的な広がりにもなりつつあることが分かる。都市から農山村への移住の傾向は，農山村をはじめとする地方圏への移住のサポートを行うNPO法人ふるさと回帰支援センターへの問い合わせ件数の増加からもうかがえ，移住希望者の年齢層もこれまで多かった60歳代以上のシニア層だけではなく，特に30歳代を中心とする現役世代が大きく増加してきている。これまでの都市生活から農山村での地域に密着した暮らしをしたいという「ライフスタイルの転換」を希望する傾向を反映したものとふるさと回帰支援センターでは分析をしている。また同じくふるさと回帰支援センターを訪れた移住希望者に対するアンケートでの移住者が希望する働き方をみてみると，2010年は農業が39.1%と一番多かったのに対して2013年になると農業を希望する人が16.8%に減少している。これと同様の傾向が地域おこし協力隊の任期終了後の進路にも見ることができる。2011年度末時点で活動地域に残った隊員のうち45%が就農をしていたのに対して2013年6月末時点では就農が26%とやはり減少傾向にある。2013年のふるさと回帰支援センターのアンケート結果では，農業にかわって企業などへの就職が35.2%と最も多くなった一方で，あらたに「起業」する自営業も15.2%となるなど，移住者にとって「農山村でのなりわい＝農(林)業」ではなくなってきており，より広い観点で農山村におけるなりわいを捉える必要がある。ところで，移住の実態を「実数」として統計的に把握することは難しい。前述のふるさと回帰支援センターの相談件数をはじめ，内閣府の調査結果など移住希望の「傾向」を把握することは可能であるが，実数を把握したものは毎日新聞と明治大学農学部地域ガバナンス論研究室の共同調査結果などに限られる。筆者らは2010年と2013年の住民基本台帳から算出した数値からその実態把握を試みたが，転入者数が増加している市町村は都市圏ではなくむしろ地方圏で広がっており，農山村では「人口」という数値の増加には反映されていないが人の流入は少なからず進んでいる状況が明らかになった。

To make the river a safe water-familiar space, we obtain the features of the water-related accidents by investigating the data-base in a newspaper, and we observe activity of children and adults around the watersides where the accidents are recorded. We obtain the following results. 1. Water-related accidents occur at a place with a lot of water-familiar activity of the children. 2. There is no cooperation between the river authority, park authority, fire station and police. It is probable that children performing water-familiar activity on the waterside are watched by adults staying on the river park. The problems lie in the lack of spatial cooperation and communication.

The purpose of this paper is to clarify how areas of activity and consciousness vary through the river's form. We chose the Kannagawa River as a case, and grasped the river's form, and made a survey about the areas of activity and consciousness of riverside inhabitants. It became clear that the areas of activity and consciousness have different characters between the upper and lower reaches of the river. And the apex of fan is the conversion point, where the river's form changes significantly. On the upper reaches from the apex of fan river doesn't act as a boundary: areas form the unity, which get over the river. On the lower reaches, river acts as a boundary of the areas.
