The hydrolysis behaviors of C.I. Reactive Orange 13(0-13). C.I. Reactive Orange 16(0-16) and C.I. Reactive Red 194(R-194) which contain monochlorotriazine(MCT), sulfatocthylsulfone(SES) and monochlorotriazine/sulfatoethylsulfone(MCT/SES) as functional groups, respectively, were investigated by chromatography(TLC, CC, PC, HPLC) and FT-IR. The hydrolytic behavior of R-194 was similar to that of O-16. but R-194 showed a good resistibility to hydrolysis in aqueolls dyeing solution than O-13 and O-16 due to its bifunctional reactive group.

An experimental study on the frequency control of an inverter heat pump to get the desired indoor room temperature has been conducted for the performance characteristics during the steady, 4, 8, and 16 step frequency operations. The heat pump model used in this study was operated to meet the experimental conditions of ASHRAE standard. The performance of the system was tested by measuring the temperature and pressure of the refrigerant, and cooling capacity, power consumption, etc. of the system. As the controlling frequency steps increased, the running time of the compressor increased as well as the electric consumption of the system and the cooling energy due to the wall heating load. However, the average cooling COP was improved.

The previous study was conducted to develop an air source multi heat pump system that could be operated with the solar collector and air source heat exchangers as heat source of the system. There is a winter-sowing problems in air source multi heat pump system when the outdoor temperature goes down under freezing point. The winter-sowing problem was solved by adapting R-22 refrigerant as working fluid in the previous study. However, when the system operated at high temperature, another problems are come out such as overheating of the solar collector outlet which lead to the superheat of the compressor inlet of the heat pump system. The condition could deteriorates a compressor in some case. In this study, we installed the anti-superheating devices on the previously developed system. As results of system performance test, COP of the system with anti-superheating technique is 2.4. It is a little improved COP compare to previous study's 2.23. In the results of multi heat source heating system, during operating solar collector, COP is relatively high between $200\;W/m^2$ and $400\;W/m^2$ solar intensity. It is recommended to extend the study on performance optimization with balancing the solar collect and capacity of compressor at higher solar irradiation conditions.

The resist and discharge behaviors of an addition type reactive dye, C.I. Reactive Blue 19, with three resisting agents in resist or discharge printing of cotton fabrics were investigated by visible spectrophotometer, FT-lR and IH-NMR. Resisting agents used were formaldehyde sodium bisulfite(FASB) , benzaldehyde sodium bisulfite(BASB) and glyoxal sodium bisulfite(GSB). It was confirmed that the resisting agents reacted with the activated vinyl sulfone group of dye and formed inactive dye complexes prior to reacting with cellulose. Three resisting agents showed good resistibility and the order was BASB > GSB > FASB.

This paper focuses on examining the Chinese-Koran translation aspect by comparing the information structure in the source and target text of the Vajrachedika Prajnaparamita Sutra. Its text is typically developed with four types by Buddha s reply from Subuti s question, which can be classified as acceptance, sermon, persuasion and avoidance. Firstly, in the acceptance and sermon type, the source language appears to be the same information flow as the target language. However, the persuasion type of target language is a little different from the source language because of addition or lexical substitution by the translator s intervention. Lastly, the avoidance type does not happen in their conversation. Through this analytical content, we can know that the same information structure of the source and target languages in the Chinese-Korean translation of the Vajrachedika Prajnaparamita Sutra is due to the strategy of literal translation and the similar information flow of Chinese and Korean languages. Therefore, the comparison method by information structure of the two languages is a useful tool to look into translation.

This paper focuses on examining why Buddhist scriptures chose transcription and observing what characteristics they have, based on it. As an analytical result of the prajnaparamita sutra translation, the reason for choosing transcription was due to the norm of the Five Loss and Three Difficulties. Through this translation restriction, the translation of Buddhist scriptures includes the characteristics which requires a controlled norm and the message conveyance which is based on transcription unlike other general translations. It shows the translation method which conveys the original meaning, respecting the source text.
