Momoko died last year. She was a great and very famous woman from Shimizu. Nevertheless, the international students who lived in Shimizu did not know anything about her. I used Momoko as the basis for a one semester Project Work investigation. Results indicated higher levels of class attendance, and increased levels of cooperation and active participation among learners.

This thesis tries to demonstrate the important role that the partnership system between farmers and developers led by the former has played in realizing the land consolidation project for enlarged paddy field, above all building a consensus among the parties concerned. The land consolidation project so realized has two types, the one involves developers and the other is of purely agricultural sector. The case I chose is Inbanuma Land Improvement District in Chiba Prefecture.
Among the areas in that district, Yachiyo area and area are the ones where the land consolidation projects for enlarged paddy field that involve developers are in progress. And of the two, the parties in area have realized the more appropriate project for making rice farming more productive.
In area, where the farmers are engaged in the progressive land consolidation projects for enlarged paddy field, those projects have been realized in larger units. The reason for this is that the famers in are effectively making use of the partnership system between farmers and developers which is achieved and kept effective in Inbanuma Land Improvement District.
What makes the farmers in area make use of that system is the fact that the system enables people other than farmers to participate in those projects and so exempts farmers from payment for construction.
In my Opinion, to promote the land consolidation projects for enlarged paddy field in present Japan, farmers must cooperate with those engaged in other industries. In Inbanuma Land Improvement District, a committee is organized for discussing land consolidation projects for enlarged paddy field so that farmers will be exempted from the burden of paying the construction cost by those engaged in the construction sector. area is an area where farmers are utilizing this committee effectively, and, due to this fact, land consolidation projects for enlarged paddy field which disburdens farmers of payment for construction are being promoted.

　「さくらさくら」は我が国を代表する歌として内外に広く知られているが, その唱歌としての成立過程や, 学校音楽教育の必須の教材として位置付けられる過程については解明されずに今日まで, 「日本古謡」として扱われてきた。本稿は, 明治21年発行『箏曲集』の「櫻」の原曲についてのこれまでの諸説を整理し, この「櫻」を原曲とする唱歌「さくらさくら」が学校音楽教育の中で重要な位置を占めるに至った過程を明らかにすることを目的とするものである。研究の結果, 現行の「さくらさくら」の楽曲としての原曲は『箏曲集』所載の「櫻」と位置付けられること, しかし山田流箏曲の手ほどき歌として以外には『箏曲集』編纂の前後から昭和前期に至るまで「櫻」が広く歌われていたという形跡が見られないことが明らかとなった。「さくらさくら」が教材として確固とした位置を得るのは, 国民学校期芸能科音楽で『うたのほん 下』に『箏曲集』の「櫻」の替え歌として掲載されて以降のことである。従って, この「さくらさくら」を「日本古謡」とすることの妥当性が問われるべきである。

The shelf-life of “-dembu”, seasoned cod meals, is not long because of discoloration or browning.
The phenomena were considered to be caused partly by rays.
The authors prepared cod meals, each of which was colored with one ingredient of coloring substance and adjusted each of the water contents ranging from 5 to 30%.
Each of all the materials was divided into three groups and packed with three film materials having different permeability against rays and oxygen. All samples were irradiated with ultraviolet ray and then the differences of color were measured.
The results are as follows:
(1) The least discoloration was measured with the “-dembu” samples packed with the film having the lowest permeability against ultraviolet ray.
(2) The strongest discoloration was found with the samples colored with Red 103 or Red 104. The discolortion of “-dembu” products may be caused chiefly by that of these coloring substances.
(3) The higher the water content of the sample was, the stronger the discoloration by irradiation with ultraviolet ray was. However, the curves of the increase of discoloration versus water content were not exponential; but distinct increases were noticed with the samples with water contents between 10 and 20%.
