Comparison of Physicochemical Properties of Chinese and Japanese Japonica–Type Rice Varieties
No full textThe physicochemical properties of 10 Chinese varieties were compared with those of Japanese varieties. Chinese and Japanese varieties were not significantly different in amylose content. However, maximum viscosity and breakdown value were significantly lower in the Chinese varieties than in the Japanese varieties, and protein content and hardness/adhesion ratio were higher in the Chinese varieties. In the Japanese varieties, the lower the amylose content, the lower was the protein content, which is a preferable quality for palatability. However, the lower the amylose content, the higher was the protein content in the Chinese varieties. In the Japanese varieties, the protein content was negatively correlated with amylogram properties and positively with texture properties, but the opposite tendency was observed in the Chinese varieties. Among the physicochemical properties of the Chinese varieties, the most serious problem was protein content; especially there is a need to disrupt the negative correlation between protein content and amylose content
Molecular Diagnosis of the Biological Control Agent Nesidiocoris tenuis (Tobacco Plant Bug) and Its Allied Species (Insecta: Hemiptera) Using COI Barcoding
No full textDNA barcoding is a useful molecular method for identification of certain animal groups. It uses partial DNA sequences of mitochondrial genes such as the cytochrome c oxidase subunit I (COI) gene. In this study, effectiveness of the COI barcoding as an identification tool for Nesidiocoris tenuis, which is used as a biological control agent, and for its allied species, was evaluated. All the species used in this study had a distinct COI barcode sequence, and the Neighbor–Joining (NJ) tree based on COI sequences almost matched the morphological classification for most genera investigated in this study, except for the genus Cyrtopeltis. The average interspecific genetic distance between N. tenuis and its allied species was 111 times higher than the average intraspecific genetic distance. The tree showed shallow intraspecific divergences and deep interspecific divergences. Therefore, our results suggested that COI barcode for N. tenuis and its allied species can be used as an effective identification tool by entomologists, quarantine experts and other related researchers, and can provide directions to taxonomists for further taxonomic studies
Production and Marketing of Renewable Energy Led by a Local Government and Structural Analysis on Residential Recognition of Selecting a Power Producer and Supplier
No full textはじめに みやま市における新電力事業 分析モデルと仮説 アンケート調査とデータの特徴 分析結果と考察 おわりに再生可能エネルギーによる地域振興が推奨されているが，そのほとんどの地域は外部事業者からの投資であり，売電収入の多くが地域外へ流出している．そのため，再生可能エネルギー事業が農山村の活性化に必ずしもつながっていない．しかしながら，「みやまスマートエネルギー株式会社」は，福岡県みやま市が主導する新電力事業者であり，平成28年4月からの電力の小売全面自由化に向け，市内のメガソーラーと一般家庭等から供給される太陽光発電による電力を購入・販売し，その利益を地元に還元することを目的に設立された．そこで，本研究では，みやま市住民を対象に構造方程式モデリングを用いて，従来の大手電力会社から地元新電力会社に電力購入先を変更するにあたり，どのような要因が住民の思決定に影響を与えているかについて分析を行った．その結果，「新事業への期待」「環境配慮行動」は，新電力への「切り替え意欲」にプラスの直接的影響を，電力供給の「安定性への不安」はマイナスの直接的影響を与えたことが明らかになった．また，「地元への愛着」が大きいほど「新事業への期待」が大きくなること，さらに「政策知識」が多いほど新電力事業者による電力供給の「安定性認知」が高まり，「安定性への不安」が減じることによって，プラスの間接的影響を与えることが明らかになった．Though renewable energy for regional developments are recommended, most of projects are invested by the initiative incorporates participants from outside the areas, and almost power selling benefits are out-flown outside the areas. Because of this, the renewal energy business has no connection with the revitalization of rural areas. On the other hand, \u22Miyama Smart Energy Co., Ltd.\u22 is a Power Producer and Supplier（PPS）and was established by the Miyama City, Fukuoka Prefecture. The purpose of this PPS is to buy and sell electric power produced by solar power generation in this city, and to return the profits to the local residents. Therefore, this study conducted surveys to residents of Miyama city as target population, used the Structural Equation Modeling as methodology, and analyzed factors - how PPS affected the change of the new local power company from the past major power company. As results, \u22expectation to new business\u22 and \u22environmental considering action\u22 had a direct positive effect on \u22willingness to switching to PPS\u22, and \u22uneasiness to stability\u22 for power supply had a direct negative effect. Moreover, the more \u22attachment of hometown\u22 led to the more\u22 expectation to new business,\u22 which had an indirect positive effect toward \u22willingness to switching to PPS\u22. Furthermore, the more \u22knowledge of policy\u22 increases the more \u22recognition of the stability\u22 for power supply, and then decreases \u22uneasiness to stability\u22, which had an indirect positive effect toward \u22willingness to switching to PPS\u22
