  • A study on the solidification of sludge by reactive amendment agent was carried out in this paper. The reactive amendment agent used in this study is mainly composed of inorganic solidification agent and reactive adsorptive material. The reactive agent has a function of soil-cement-agent solidification and harmlessness of contaminant in waste. The reactive agent is environmentally friendly material to the surrounding environment. In this study, a series of tests and experiments including unconfined compressive strength, permeability, pH test, constituent analysis, leaching test were carried out to analyse engineering and environmental characteristics of solidified sludge treated reactive agent. The result of this research shows that the solidified sludge treated reactive agent is increased in strength and decreased in contaminant concentration.

  • Mobile agents have the unique ability to transport themselves from one system in a network to another. The ability to travel allows mobile agents to move to a system that contains services with which they want to interact and then to take advantage of being in the same host or network as the service. But most of conventional mobile agent systems require that the users or the programmer should give the mobile agent its detail behavioral script for accomplishing the given task. And during its runtime, such mobile agents just behave according to the fixed script given by its user. Therefore it is impossible that conventional mobile agents autonomously build their own plants and execute them in considering their ultimate goals and the dynamic world states. One way to overcome such limitations of conventional mobile agent systems is to develop an intelligent mobile agent system embedding a reactive planner. In this paper, we design both a model of agent mobility and a model of inter-agent communication based upon the representative reactive planning agent architecture called JAM. An then we develop an intelligent mobile agent system with reactive planning capability, IMAS, by implementing additional basic actions for agent moves and inter-agent communication within JAM according to the predefined models. Unlike conventional mobile agents. IMAS agents can be able to adapt their behaviors to the dynamic changes of their environments as well as build their own plans autonomously. Thus IMAS agents can show higher flexibility and robustness than the conventional ones.

  • The dye-resist effect of reactive dye-resist agents in reactive dyeing of silk was investigated. The dichlorotriazine-based dye-resists achieved a higher effectiveness than others since they make a charge barrier of diffusion in the silk fiber periphery due to high reactivity of dichlorotriazine group. Similarly, in the case of hetero-multifunctional dye-resist agent, the dye-resist agent containing both a dichlorotriazine and an ${\alpha}$-bromoacrylamide reactive groups achieved better resist effectiveness than those containing both a monochlorotriazine and an ${\alpha}$-bromoacrylamide groups. Also, their resist effectiveness was improved by increasing the number of sulfonate groups in the dye-resist agents and the number of reactive groups in the reactive dyes applied to them.

  • To be dyed with cationic Berberine, the cotton fiber was modified with reactive anionic agent. The Berberine, a natural cationic colorant of pure yellow, is the major component of Amur Cork tree extract and also can be employed as a natural antimicrobial agent due to its characteristic of cationic quaternary ammonium salt. By LC/MS analysis, it became obvious that the Berberine was contained in Amur Cork tree extract as a major color component. The adsorption of the Berberine on the cotton fabrics pretreated with the anionic agent was greatly increased comparing to that of untreated fabric. Because the anionic agent was colorless, it did not cause unintended color change of the dyeings. The dyed fabric with the Berberine has strong antimicrobial activity showing 99.5% of reduction of bacteria against Staphylococcu aureus.

  • The influence of the concetration of the discharging agent on some properties of silk fabric dyed with reactive dyes studied. The tensile strength, yellow index and whiteness were investigated as parameters to determine the effect of the dischanging agent. The results were summarized as follows ; 1. The tensile strength and the yellow index decreased with the increase of the concentration of the discharging agents. 2. The whiteness depended on both of the type and the concentration of the discharging agent.

  • In order to examine the P.H.C pile raw material using glass forming ceramic. The used materials is ordinary portland cement, waste TFT-LCD glass powder and reactive agent(Ca$(OH)_2$). The first experiment is characteristics analysis of the waste TFT-LCD glass powder, For the second experiment is mortar and concrete compressive strength for using of the concrete file raw material for waste TFT-LCD glass powder. The results of experiment showed that the substitution ratio of 10% waste TFT-LCD glass powder and 1% reactive agent(Ca$(OH)_2$) was excellent at a point of view for the physical characteristic. The study's most important finding is that the recycling of waste TFT-LCD glass powder.

  • This study was carried out to investigate increasing the neutral substantivity of anionic dyes for cationic-modified cotton fabric treatied with cationic agent. In the present study 3-chloro-2-hydroxypropyltrimethyl ammonium chloride for reactive cationic agent was produced by reaction of epichlorohydrine with trimethylamine hydrochloride. 3-chloro-2-hydroxypropyltrimethylammonium chloride was converted in an aqueous solution of sodium hydroxide into glycidyltrimethylammonium chloride. By treating with this epoxy reagent the hydroxyl groups of cotton fabric was modified to trimethylammonium group through ether linkage. The introduction of new cationic sites into cotton fabric by pretreating with cationic agent improves the substantivity of anionic dyes with the cotton in dyebath. Dyeablity of the modified cotton fabric for direct and reactive dyes was much improved in a non-electrolytic or a little electrolytic dyebath and was proportional to the concentration of cationic agent.

  • The anionic agent containing dichloro-s-triazinyl reactive group was synthesized and applied to the cotton fabrics to introduce covalent bonds. This attempt was expected to improve the affinities of cationic compounds, such as cationic dyes, chitosan, quaternary ammonium antimicrobial agents and metal ions, by the electrostatic attractive force. As expected, the anionic agent was reacted with cotton fabrics at room temperature. In order to examine the adsorptivity of the cationic compounds on to the anionized cotton fabrics, firstly a cationic dye(C. I. Basic Violet 7) was applied. The color strength of the dyeing of anioized cotton fabric was highly increased comparing to that of untreated fabric.

  • The effects of agents in padding liquor on the fixation of vinylsulfonyl reactive dye of ground color and on the resist-dischargeability in resist-discharge printing of cotton fabrics with reactive/reactive dyes were investigated. Alkalis, such as sodium bicarbonate, sodium carbonate, sodium acetate and trichloro sodium acetate, were used to fix the dye for ground color on cotton fabrics. Sodium bicarbonate and sodium carbonate showed a good fixation of the dye for ground color, but they were ineffective to the white and the colored resistdsichargeabilities, which were caused by the fast fixation of the dye for ground color before its reaction with resist agent in printing paste. Therefore these are not suitable for the agent to fix the dyes for ground color because they deteriorate the resist-dischargeability. In case of sodium acetate, as the fixation yield of the dye for ground color was remarkably low. and the white resistdischargeability was not good, it had better not be used for the agent to fix the dye for ground color. However, the addition of sodium trichloroacetate to padding liquor gave a very good fixation yield of ground color, and showed an excellent resist-dischargeability. The effects of acetic acid in padding liquor on the fixation of the dye for ground color and on the resist-dischargeability were studied in case of immediate printing of resist-discharge pastes after padding and drying and in cases of printing after 1∼3 day-storage of padded goods. By the addition of 2% of 48% acetic acid aqueous solution to padding liquor, the white and the colored resist-dischargeabilities were improved and the fixation of the dye for ground color was good without any troubles. Especially, when the padded goods were stored for 2 or 3 days and printed with resist-discharge printing pastes, its addition was very effective on the resist-dischargeability.
