  • In the evaluation method of KS on the activity factor of fly ash, same amount of cement should be replaced with fly ash. Therefore, contradictory effects on concrete strength exist, i. e. strength decease due to low content of cement and strength increase of strength due to filling-pore-function of fly ash. European Committee for Standardization (CEN) specifies the method 1 to 4. adding fly ash without reducing the content of cement, for the evaluation method on activity factor of fly ash. This study investigates the applicability of the method 2 of CEN to mix design of concrete. The followings are derived ; There is a key ratio of f)y ash mixing which enhances the incremental ratio of mixing water to improve fluidity of mortar. The incremental ratio of mixing water is maximized about 11% ratio of fly ash mixing. Compressive strength most slightly increases at that ratio of fly ash mixing. Activity factor of fly ash increases as water-cement ratio becomes low and contents of fly ash becomes high. Moreover, quality of fly ash and condition of mix design affect the applicable amount of fly ash and available range of water-cement ratio. However, this method has some problems for practical purpose because activity factors of fly ash for some cases are over 1.0. Further research should be conducted to develop more useful method of evaluating activity factor of fly ash.

  • There are various types of noise around us such as road traffic noise, aircraft noise and floor impact sound, equipment noise, etc. Researches on the noise criteria and the evaluation method for the diffuser noise of HVAC are insufficient. dB(A) and NC values represented in ASHRAE guide book are applied as a noise criteria for diffuser noise, which have some problems like that the values between dB(A) and NC have deviation even if the sound is same one. Therefore, the evaluation method should be considered and proposed based on the subjective responses. From these reasons, this study aimed to analyze the evaluation factors for the diffuser noise of HVAC reflected on the subjective responses by surveying vocabularies and grouping them with factor analysis.

  • Background : Quality of professional nursing care is the most essential factor for survival and growth of nursing profession. Then, nursing professionals have responsibility for the evaluation of quality of professional nursing care. The purpose of this study was to develope an evaluation tool of nursing care for patients received gastrointestinal surgery with general anesthesia. This study was a primary work for the developement of a computer program for the evaluation of nursing care. Methods : This study was done through some consecutive steps. They were (1) Developement of items for the tool (2) Developement of an evaluation tool of nursing care quality for the G-I surgery patient (3) Test of reliability and validity of the tool. Two groups of experts and expert pannels who had much experience of the QA and the care of G-I surgery patients participated for developement of the items. 85 nursing records were used for the test of reliability and validity of the developed tool. The evaluation tools were developed with two types of scoring, norm-referenced tool and criterion-referenced tool. Results The system of items for tool was evaluation area evaluation item-indicator. There were 7evaluation areas which contained 32evaluation items which contained 7lindicators. Evaluation areas 1, 2, 3, 4 were for the evaluation of process and 5, 6, 7 were for the evaluation of outcome of nursing care for G-I surgery patient. For the test of interrator reliability, correlation coefficients of each scores of items and intragroup correlation coefficients were calculated. The average correlation coefficients between two rators were 0.65, 0.54 and the intragroup correlation coefficient were 0.99 and 1.00 by the types of scoring. The Cronbach alpha coefficients of the tools were 0.54 and 0.46 by the types of scoring. The average content validity index of the items was 0.95 from 4 pairs of experts. Because there were significant differences between some scores of quality of nursing care of 3 general hospitals regardless of the types of scoring, the tools could be thought to have some construct validity. And also, there were significant correlations between some scores of quality of nursing care and admission days and admission days after surgery regardless of the types of scoring, the tools could be thought to have predictive validity. Conclusion In this study, the evaluation tool of nursing care was developed for the very specified group of patient, G-I surgery patient. And the items were developed and tested by the experts of nursing practice. Because of these reasons, it was supposed that the tool could be used effectively in nursing pratice. And the procedures for the development and the test of the evaluation tool of nursing care in this study were supposed to be used for the developement of other tools.

  • In this study, we assessed the antioxidant activities and quality characteristics of cookies containing various concentrations (0, 1, 3 and 5%) of Eleutherococcus sessiliflorus leaf powder. Antioxidant activity was estimated based on DPPH free radical scavenging activity and total content of phenolic compounds in Eleutherococcus sessiliflorus leaf powder and cookies. The quality characteristics of Eleutherococcus sessiliflorus leaf cookies were estimated based on spread factor, loss rate, leavening rate, color, texture and sensory evaluation, polyphenol contents, DPPH free radical scavenging activity, as well as spread factor of cookies significantly increased. L value, b value and hardness of cookies decreased with increasing Eleutherococcus sessiliflorus leaf powder content. Finally, the sensory evaluation showed the highest scores for cookies containing 3% Eleutherococcus sessiliflorus leaf powder. From these results, we suggest that Eleutherococcus sessiliflorus leaf is a good ingredient for increasing consumer acceptability as well as the functionality of cookies.

  • The purpose of this thesis is to suggest objective basic data for the environmental design through the quantitative analysis of the visual quality included in the physical environment of Basemsagol valley sequence landscape. For this, visual volumes of physical elements have been evaluated by using the mesh analysis, spatial images structure of physical elements have been analyzed by factor analysis algorithm, and degree of visual quality have been measured mainly by questionnaires. Also, this study aims to understand semiotics and to grope the possibility of application to the sequence landscape assessment. A semiological approach suggests a new dimension in sequence landscape assessment, which is a contrast to the existing scientific evaluation methods. Result of this thesis can be summarized as follows. Visual volumes of the immediate vegetation, rock, bridge, road and distant vegetation are found to be the main factor determining the visual quality. Factors covering the spatial image of natural park sequence landscape have been found to be the overall synthetic evaluation, potentiality, natural quality, spatial, appeal and dignity. By using the control method for the number of factors, T.V. has been obtained as 40.22%. The characteristics of the semiological approach is qualitative, open, holistic, and experiential, whereas that of the scientific approach is quantitative, closed, reductive, and experimental.
