The plum has been treated in Japanese ancient literary works. But Gozan literary work has a relationship with the Song Dynasty works, especially Zen philosophy. They did choose to write more often of the plum. This behavior is different from the Heian literature.

Avifauna of Shoganji Pond or Lake Saiko, Gunma National College of Technology, was investigated from April 2007 to September 2009. More than 60 species of birds including semi-endangered species were observed on the pond. Common moorhens, black-crowned night herons and some other species were found to propagate in reed field on the pond. Twenty thousands of starlings and fifty or more egrets were observed to colonize during summer nights. Green-winged teals and some other ducks were found to arrive in September and spend the winter on the pond, and hawks were observed at the same time. The pond with its biodiversity proposes itself as a potential field for environmental studies.

The "common examination" of mathematics for the 3^rd grade students in Gunma Kosen, who correspond to the 12^th grade students of high school in the USA, has been carried out for ten years. The examination distinguishes itself from other traditional examinations done in Kosen to cover a wide range of topics in mathematics. In the present paper, the history of the common examination is summarized, and the results of the examination for the last decade are analyzed. Finally, the future problem is discussed.

Gozan literary work had a relationship with the Song literature. Song poems were said to a prosaic and logical. Gozan poems also logical. Gozan poet did choose to write more often of the poem in their poems, with Song literary theory.

The collector current of actual bipolar transistors in the satulated region increase with the collector voltage. This phenomenon is called the Early effect, and the voltage at which the expolated output curves of bipolar transistors is called the Early voltage. The Early voltgae is usually estimated using the Gummel-Poon model. However the Gummel-Poon model is a little difficult to learn for beginners. In this paper the estimation of the Early voltage using the Gumle-Poom model and that by Taur and Ning are shown. Then the estimation of the Early voltage using the elementary model by the author is shown, and the numerically calculated results are also shown. The estimation using the elementary model may be useful for the begginers to understand the behavior of bipolar transistors.

There are many books about criticsm of the Waka poems in Muromachi era. They have traditional way of waka. Chinese Song literature was introduced into Mromachi era. So criticsm of the medieval Waka poems has a relationship with the Song Dynasty works.

We analyze a recreation game called Yamanotesen-Game using methods of game theory. We compose some simple models of Yamanotesen-Game and compare their Nash and Bayesian equilibrium points with the actions of players of Yamanotesen-Game in real world.

Peter Dickinson is a British writer, though his birthplace is not in England : in 1927, he was born in Northern Rhodesia (now Zambia), Africa, where his father had worked as a British civil servant. Young Dickinson spent his first seven years in this strange African country, which would probably influence his future career. After graduating from King’s College, Cambridge, in 1951, he started to work as assistant editor at Punch, the famous humor magazine. Thanks to his much experience of reviewing mystery novels, Dickinson himself succeeded in making his debut as a novelist in the same genre in 1968. His detective "James Pibble" series were quite popular in the 1970s among crime novel fans in the United States as well as the United Kingdom; most of them were translated and published even in Japan.
Now, however, Peter Dickinson seems to be recognized as a first-rate writer of fantasy and science fiction for young readers. In Japan it cannot be denied that his name sounds unfamiliar to most people, but it appears there are some avid fans of his fantastic world.
My Japanese version of "The Spring" belongs to this wonderful genre of fantasy for children. The work was chosen and translated from The Puffin Book of Ghosts and Ghouls (ed., Gene Kemp, Penguin, 1993). I hope that "The Spring" will be enjoyed in the Japanese language with some fresh surprise.

Photoisomerization was found to take place both in distyryl (1) and bis (p-dimethylaminostyryl) (2) substituted organoboron compounds. Photodecomposition simultaneously proceeded in 1. The compound 2 did not show noticeable photodecomposition in isopropyl alcohol (IPA) but was found to show rapid photodecomposition in halogenated solvents such as carbon tetrachloride. Benzoylperoxide was observed to facilitate photodecomposition of 2 even in IPA. Photolysis of 2 dispersed in polymer matrices was also examined. The photodecomposition rate was increased with dielectric constants of the polymers.

The relationship between the crystal size of zeolite LTA nanocrystals and the molar composition of reactant mixture has been investigated in order to prepare the regularly oriented and highly dense zeolite LTA films. The building-block zeolite LTA nanocrystals which have various crystal sizes have been synthesized by controlling the molar composition of starting materials, Al, tetramethylammonium hydroxide (TMAOH), NaCl, and H₂O. Using the nanocrystals with controlling TMAOH content and H₂O content, the zeolite LTA thin film have been obtained. These thin films have been fabricated from the suspension of the zeolite LTA nanocrystals. The morphology and the density are different on the variation of the TMAOH content and H₂O content. There are many craps between the building-block crystals on the film and the surface is rough with decreasing the H₂O content. Their crystal shape remains cubic when the crystal size decreases. On the other hand, with the change of TMAOH content, more regularly oriented assembly is obtained. The edge of cubic crystal becomes less sharp. The shape of zeolite crystals becomes spheres with decreasing the TMAOH content. These surfaces of the films are regularlly oriented and highly dense. It is considered that the reason is the building-block crystals of zeolite LTA have such sphere shapes.

It is generally accepted that amount and balance of lipid and carbohydrate, not only protein, in feed affect feed utilization and protein retention of culture fish. They are, then, fed with high energy feed, causing high cost for aquaculture, loss of food resources, deterioration of meat quality because of lipid oxidation and ecological despoliation. Control of lipid and carbohydrate metabolisms in culture fish will enable us to manipulate feed utilization of culture fish more efficiently. The aim of this study is to reveal lipid and carbohydrate metabolisms in fish and establish methods for quality improvement of culture fish using phytosteryl hydroxycinnamate esters, such as γoryzanol (ORZ).

Many researchers advocate transit oriented development or compact city concept. However, it is necessary to obtain a rational reason on urban policy by quantitatively grasping an effect of transportation mode on city growth. In this reason, we developed a simple simulation model that can compare the differences between automobile-oriented and transit-oriented cities, and clarify the difference among city forms by transportation mode. Following a theoretical model development, a series of simulation runs are tried. The model allocates people who commute to CBD from residential zones along a transportation corridor. As a result of many simulation runs, it is shown that automobile requires much more traffic space than transit.
In this paper, the improvement on the model is proposed using Linear Programming. It is an improvement for the purpose that the model can be applied to more general city forms. Through the trial, we confirm that the solution of LP model exists.
