Evaluation of environmental

In recent years, climate change and population problem

and economic impacts ofhave become more apparent and serious. As one of thewoody biomass district

solutions to these problems, woody biomass heating has

heating systems considering

been attracting attention. The purpose of this study is toconsumer characteristics

estimate the CO2 reduction costs of each woody biomass
heating systems in typical consumers and to explore more
effective use. The estimation results show that the CO2
reduction costs are below 30,000 yen/t-CO2 for all
consumers and district heating systems are more costeffective than individual systems for almost all the
consumers. Woody biomass heating could be more costeffective in the case of consumers with higher building
density and smoother heat load patterns.

accidents, it is necessary for foreign workers to takeappropriate measures. Furthermore, in order to prevent
occupational accidents, a positive awareness of people's
safety is important, and the impact of human perception
cannot be ignored. It is considered that obtaining
knowledge about consciousness of safety behaviors ofpeople of different genders, nationalities, and grades willcontribute to the prevention of occupational accidents. In
this study, we calculated the weights of various students'
safety behavior consciousness using the hierarchicalanalysis method from the data obtained by thequestionnaire survey for university students in three
countries. We examined the differences in human safety

Gels consist of a solvent and a small amount of gelator,

amino acid gelators and theand are applied in various fields because they exhibit

structureintermediate properties between solids and liquids. Aminoacid gelators are synthesized from naturally occurring
amino acids, have strong gelling ability, and have features
such as low toxicity and good degradability. Therefore, inthis study, organogels were formed by using two types ofglutamic acid-derived gelators and various organic solvent.
We examined organic solvents that can be gelated byglutamic acid-derived gelators and examined the structure
and properties of organogels.

Preparation and fire

In order to develop a new high-performance fire

suppression capability ofextinguishing agent, a liquid fire extinguishing agent

aqueous dispersions ofconsisting of submicron ferrocene particles dispersed insubmicron ferrocene particles

water was prepared. The fire extinguishing performancewas evaluated by the time required to extinguish an nheptane pool fire. We found that aqueous submicron
ferrocene dispersions with high fire extinguishing
performance can be prepared by using a poor solvent
precipitation method with organic solvent as the good

solvent and water as the poor solvent, and the initialconcentration of ferrocene is more than 1000 ppm, thefinal concentration is more than 100 ppm, and theconcentration of organic solvent is less than 10 vol%. It isalso possible to combine the positive effect of submicron
ferrocene particles on the fire extinguishing performance,with the positive effect of aqueous organic solvent
solutions which form an azeotropic mixture with water.

Wetting Morphology Diagram

The wetting morphology of an object varies depending onof Helical Filaments under

the shape of the object, as well the interfacial property.

Pressure Control

In this experiment, we aim to construct wetting
morphology diagram of the helical filaments (or coil) underpressure control condition. Based on the observation ofwetting the morphologies at different coil pitch p anddifferent pressure difference ΔP between the inside andoutside of the liquid, a coil wetting morphology diagram
was created in which the vertical axis is ΔP and thehorizontal axis is p. In the p range from 2 to 7 mm, twowettingmorphologies is realized, and there is a critical pressure
difference between 10 and 20 Pa.

The aim of this study is to analyze the electrolytic reaction

electrolysis for ammoniumof ammonium dinitramide (ADN). ADN-based ionic liquid

dinitramide toward thepropellants (EILPs) have low vapor pressure and candevelopment of electrolysis

reduce suction exposure of workers. However, thermal

ignition systemstability causes the difficulty of ignition and need a large
amount of thermal energy for decomposition andcombustion. Therefore, in this study, we devised anelectrolytic ignition different from pyrolysis ignition andthen verified the ignition possibility of ADN-based EILPs
after selected a fuel suitable for electrolytic ignition. In
addition, the electrolytic reaction of ADN was estimatedfrom the electrochemical properties and the electrolytic
product.

intermolecular distance leads to expansion and contract offiber length. It is suggested that the difference of density
in the fibers causes the bending of the fiber. In addition, I
investigated vapochromism and shape change of 6T4A-Ph
fiber from various solvents.
