Since solar power generation has increased rapidly, balancing function, especially in the form of increasing demand, is becoming needed. We proposed technique of active demand creation in previous study in which an aggregator dispatched home appliances expected to be IoT-ready in the near future in order to consume the surplus deriving from over-generation of solar energy.

In this study, we evaluate operating characteristics of PCS by experiment on active demand creation co-operated with solar power generation. In this experiment, our demand dispatch system implemented in previous study sends mitigated curtailment rate to existing PCS. Deference between demand creation characteristics and PCS output characteristics is discovered in the experiment and a solution to this challenge is proposed in this paper.

　吟醸酒は，今や多くの蔵元で製造され一般に消費されている清酒となってきたが，昭和40年代位まではそうではなかった。著者は，長年にわたり吟醸酒の普及に尽くされ，幻の日本酒を飲む会を主宰してこられた。その著者が，「比べ飲み」を通じて吟醸酒を初めとする清酒の策を提唱している。参考にして，実践したいものである。

本論文は，山口県萩市における水産物産地市場の再編状況を把握し，また，直販施設である「萩しーまーと」の果たしている役割を検討することを目的とする。

萩市では，2001年に，市場価格の上昇や取扱量の増大を求め，8つの産地市場を廃止し，漁獲物を1つの市場に集中させようとした。しかし，再編後，人件費の削減以外に明瞭な影響は見られなかった。他方で，少量他品種な水産物がより流通しにくい状況が起こっている。「萩しーまーと」は，経営の安全性を確保した上で，そのような水産物を出来るだけ販売しようと心がけていることが特徴である。

In this study, we developed a bearing wall with higher strength using CLT for seismic reinforcement of the first floor part of wood frame-based building method housing, and experimentally confirmed the in-plane shear performance of the load bearing wall. We also attempted numerical analysis of the shear performance of the high-strength shear wall based on the performance of each element used in its construction. The results showed that our high-strength shear wall attained its target value, and applied numerical analysis was effective for evaluating its safety.

The objective of this study is to investigate the performance of co-generation systems in commercial buildings in various regions in Japan taking into account the contribution to business continuity plan (BCP). An energy simulation tool named "BEST" was employed to calculate the energy demand of non-residential buildings under regional climatic conditions. The additional electricity for BCP were estimated based on the simulated energy demand, which indicates good agreement with the literature data. By introducing cogeneration, the possibility was evaluated quantitatively to achieve both energy savings and securing the electric power necessary for BCP. The results show that some cases can attain both of them. In addition, this study analyzed the performance of demand response (DR) by switching co-generation to an electric power-based air-conditioning system. The numerical example suggests that the operation will be effective and possible not to increase primary energy consumption even with DR.

The main purposes of this study are: 1) to elucidate the trend of demand for Welsh onions; 2) to elucidate the regional disparity of demand for Welsh onions. The trend and the regional disparity are analyzed by the demand functions.
The results of this study are follows: 1) in the winter season Welsh onions have a great demand. However, according to the price elasticity of demand for Welsh onions in the Osaka Central Wholesale Market, the demand is increasing in the summer. It means that there is a tendency for demand of Welsh onions all year round; 2) the income elasticity of demand for Welsh onions is large in the summer. Therefore the demand is expected to increase in the summer; 3) in the future, it is possible that the demand in major cities of the Western Part of Japan increases. There are two reasons for this: i) as a region moves to the west, the price elasticity and the income elasticity of demand for Welsh onions become larger and larger; ii) Welsh onions consumption per head of major cities is larger than that of any other city.
Also in this study we conclude that Welsh onions are considered essential goods depending on the price elasticity of demand.

Engineering study in the field of aerospace is an effective way to enhance the student motivation. The young students can be attracted by the research and development aiming at returning its results to the public society. The Muroran Institute of Technology is carrying out the practical education in the field of real research and development by the Aerospace Research Center. The projects of the center is being performed well in cooperation with the national research organization and the private companies and thereby the students have the good opportunity to find the actual situation of the real world.

It is said that it is necessary to build a hydrogen-based society in order to realize carbon neutrality. However, the reality is that the social implementation of hydrogen has not progressed. In order to realize a hydrogen-based society, it is necessary to solve many issues, and for that reason, the Japan Hydrogen Association was established in December, 2020 as a cross-industry organization. This association is participated by many companies and organizations from various industries, and will accelerate the social implementation of hydrogen with an all-Japan.

It is said that advertising of vegetables has little effect on the expansion of these demands so far. But recently, advertising is getting important for places of vegetable production, because many places of vegetable production intend to differentiate their products from the products of other places.
This paper attempts to analyze the effect of advertising on vegetable demands. The vegetables are the onion and the potato which are advertised under “The Hokuren Program for Expanding Consumption of Onion and Potato.” The advertising variable which summarizes the influence of current and past advertising expenditures on demand is used to estimate the impact of advertising on demand. The Pascal distributed lags are used to account for the influence of current and past advertising expenditures.
Both parameter estimates of advertising variables in onion and potato equations are statistically significant. But the effect of advertising on the onion demand is different from that on the potato demand. The onion demand is quickly affected by the advertising, whereas the potato demand is slowly affected. Using the estimated equations, the effects of advertising on their demands are valued by the simulation analysis. If the price elasticities of supply of these vegetables are less than 1.0, the increase in supplier surplus is greater than the advertising cost of this program.

イエバエの食糞性を利用して鶏の排泄物を分解処理し,その際得られる大量のイエバエ幼虫および蛹の,鶏の飼料原料としての価値を検討した。イエバエ幼虫および蛹の乾燥粉末は,粗蛋白(CP)約60%,粗脂肪約20%を含み,アミノ酸組成は魚粉に類似し,家畜•家禽の飼料原料として,十分な利用価値があると考えられた。幼虫と蛹の比較では,1個体当たりの体重が幼虫の方が重いことから飼料原料としては幼虫がより適していると思われた。幼虫乾燥粉末原物の鶏におけるエネルギー代謝価(ME)は3.79kcal/gと算定された。体成分の分析結果とエネルギー代謝価に基づき,CP,ME,アミノ酸組成が同等となるようイエバエ幼虫乾燥粉末7%含有の試験飼料と,魚粉(ホワイトフィッシュミール)7%含有の対照飼料を調製した。両飼料ともブロイラー前期養分要求量を満たしていることを確認し,孵化直後から24日齢までブロイラーに対する飼養試験を実施した。試験飼料と対照飼料を与えた雛の間に,増体量と飼料要求率に有意差は認あられなかった。24日齢で屠殺した雛の中抜き体重(可食部と骨部の合計)の生体重に対する割合は,試験飼料投与群が対照飼料投与群より有意に高かった。これらの雛の腿肉の,蛋白質,脂肪の含有率,アミノ酸組成に,投与飼料による違いは認められなかった。以上の結果から,イエバエ幼虫乾燥粉末は鶏の飼料原料として,魚粉と同等以上の栄養的価値があることが示された。

Since solar power generation has increased rapidly, balancing function, especially in the form of increasing demand, is becoming needed. We propose technique of demand response in which an aggregator dispatches home appliances expected to be IoT-ready in the near future in order to consume the surplus deriving from over-generation of solar energy.

In this study, assuming that such an aggregator could be an energy retailer as well, this demand dispatch is provided to customers as an energy service and also offered to the power system operator as a balancing function. An experimental demand dispatch system is implemented, and challenges are pointed out such as an error between target demand value to be increased and actually dispatched demand value.
