Lettuce was grown under pulsed white LED light at variation pulse cycles and DT ratios (illuminated period/cycle), and the relative growth rate per unit luminous energy and photosynthetic rate were examined. Both the growth rate and photosynthetic rate were generally increased (except at a pulse cycle of 10ms and a DT ratio of 50%) compared with continuous illumination. Particularly, both the growth rate and photosynthetic rate were increased by 20% or more at a pulse cycle of 400μs and a DT ratio of 50%. A further slight increase in the growth rate was observed when the DT ratio was 33%. These results may be explained by the presence of a period of 200μs duration in which light is unnecessary (period of electron transport) in the light reaction of photosynthesis. This study supports the feasibility of LED plant factories.

Absorption of nitrogen oxides into the soils were measured in a gas chamber by an automatic continuous nitrogen oxides analyzer (with Saltzman reagent). The capacity of absorption of nitrogen oxides differs greatly due to the sorts of the soils. The soils gradually released nitric oxide at room temperature, and the concentration of the released nitric oxide is nearly proportional to that of original gas concentration. Nitric oxide and nitrogen dioxide were released by heating from the wet soil which absorbed nitric oxide or nitrogen dioxide, while only nitric oxide was released from the dry soil. The temperature at which nitrogen dioxide appears lowered with increasing the water content of the soil. Some soils even reduced nitrogen dioxide to nitric oxide. The rate of absorption and release between the soils and the atmosphere varied by the sorts, temperature and water content of the soils.

The analysis of evaluation of instruction by students can be the most powerful tool available to instructors for the improvement in their own instruction technique. A questionnaire named minute paper soliciting students' evaluation of instruction was given out to the students of 3 courses at Tokai University during 1989 every time. The minute peper has five questions: what are points of important and doubt of this instraction?, how is evaluation by yourself as student in this class?, how is evaluation of this instruction?, What are good items of this instruction?, What are bad items? In this paper, how to use the minute paper, useful point of the minute paper, relationship between evaluation value of the minute paper and total evaluation value of a semester are introduced. The minute paper had 8 useful points : it is possible to make improvement of instruction every time, to see students' understanding and others. The total evaluation value of a semester was higher than it of the minute paper.
