Vibration diagnosis of steam turbine generator is essential for safe operation. For a fast few decades, several data base systems for diagnosis of steam turbine generators have been developed and proved useful. However, there still remains a problem in using data base systems such that they require an expert engineer who has a deep insight or knowledg into the system. Moreover,such data base systems can not give any information if the input is not completely fit with data base. This paper presents an effective method for vibration diagnosis of steam turbine generators using fuzzy inference. The proposed method includes also a strategy to overcome the drawback of data base system such that one cannot obtain any information when the input is insufficient or not exact. A computer program is written to realize the entire procedure for the diagnosis. Three realistic problems are dealt with to show the effectiveness of the proposed method.

Selection procedures of earth retention systems are increasingly complex and directly related to the serviceability of the retaining structure selection systems since significant changes in earth retention technology motivates the review of design, and selection processes of earth retaining structures. Collection and classification of retaining structure selection knowledge are key issues because two expert groups, geotechnical and structural engineers, are mainly involved in the retaining structure selection. The course of natural tendency of expert knowledge are investigated considering the decision factors. The decision factors for selecting retaining structures are divided into four categories: application of the structure, and spatial, behavior, and economic constraints.

KnowledgThe Korea Institute of Energy Research(KIER) has begun collecting horizontal global insolation data since May, 1982 at different locations. Because of a poor reliability of existing data, KIER's new data will be extensively used by the solar system users as well as by research institutes. But the quality of solar insolation data is not always good. This reports on an attempt to identify systematic error in such data using clear-day analysis for data rehabilitation. Clear-day analysis is successful in uncovering solar insolation data of questionable quality. It is not proven that rehabilitation process can improve the quality of data for daily or monthly means, but it is suggested that the method can be used to improve the quality of data for monthly means of several years for use in many applications of solar energy plarming. Earlier studies finding a maximum ETR of about 0.80 are confirmed.

The antenatal self-care, one of antenatal management, was almost done by a pregnant woman herself. But It's especially difficult for primigravidas to cope with the change of being pregnant, and they also had insufficient knowledge of pregnancy, The purpose of this study was to serve as a basis for antenatal management, by grasping how much primigravidas performed antenatal self-care, how much they had maternity-related knowledge, and what factors affected those two factors. The subjects of this study were the primigravidas, selected from among visitors to a general hospital and a hospital for obstetrics and gynecology located in the city of K. A questionnaire survey was carried out over them from July 16 to August 19, 1998, to collect data. The test instrument used in this study for antenatal self-care behavior was one that modified the measurement instrument employed in studies by Kim Hae Won(1996), Lee Mi La(1984), and Yoon Young Mi(1994). Another one for maternity-related knowledge was Kim, Hae Won(1996)'s instrument. The collected data were statistically analyzed by SAS PC+. Frequency and percentage were calculated to find out the primigravidas' general characteristics, and the mean and standard deviation, rank were estimated to determine the degrees of antenatal self-care behavior and maternity-related knowledge, t-test and ANOVA were carried out to identify the general characteristic that affected antenatal self-care and maternity-related knowledge. and the relationship of antenatal self-care behavior to maternity-related knowledge was tested by Pearson correlation coefficient. The findings of this study were as follows; First, the age of the subjects ranged from 18 to 37, and their mean age was 26.43. Their mean gestational period was 24.87 weeks. 45% of the subjects were in the third-term pregnancy. Second, their total mean score in antenatal self-care behavior ranged from 94, the highest, to 36, the lowest. Its average score was 63.81(SD 9.98). The total mean score in maternity-related knowledge ranged from 20, the highest, to 1, the lowest, and its average score was 10.91(SD 4.59, 54.55 percent). Third, the general characteristics that gave impact on the primigravidas' antenatal self-care behavior were age, educational background, gestational period, experience of natural miscarriage, and experience of infertility test. A higher score in antenatal self-care behavior was gained by the primigravida group who had better educational background(F=3.29, p=.02), who was in the late stage of pregnancy(F=4.31, p=.01), who experienced a natural miscarriage(t=2.06, p=.04), and who went through a infertility test(t=-2.19, p=.04). Fourth, the general characteristics that had an influence on maternity-related knowledge were identified as the religion, the term of marriage, and the gestational period. A higher score in maternity-related knowledge was got by the primigravida group who had a religion(t=-2.02, p=.04), and who was in the late stage of pregnancy(F=5.77, p=.003). The term of marriage also made a significant difference(F=3.46, p=.02). Fifth, the relationship of the total mean score between antenatal self-care behavior and maternity-related knowledge was found to be at r=.37(p=.0001). In this study, an attempt was made to affirm the subjects' characteristics, the degree of their antenatal self-care behavior, and the extent of their maternity-related knowledge, to confirm what characteristics affected significantly primigravida's antenatal self-care behavior and maternity-related knowledge, and to verify that there was a relationship between the two variables. The meaning of this study might be backed up by the fact that its findings would serve as a basis for primigravida's efficient antenatal management in the future.
