  • Fault detection has to be proceeded by steady state filtering to get rid of transient effect associated with thermal capacity. Coefficient of variance (COV), ratio of standard deviation devided by moving average, was employed as steady-state filter. Engine speed and refrigerant pressures were selected as parameters representing system dynamics. The filtered values were registered as members of steady-state DB. They were found to show good functional relationship with ambient temperature. The relationship was fitted with a second order polynomial and the distribution bounds of the data around the fitted curve were expressed by visual inspection because of varying average and random data interval. Fault data were compared with the steady-state data obtained during normal operation. The fault data were easily isolated from the fault-free one. To make such isolation reliable, tests to construct good DB should be designed in a systematic way.

  • Motivation and learning strategies, some of the important factors affecting language learning, have mostly been studied with reference to their relationship in terms of proficiency. This study investigated motivation and learning strategies and their relationship in order to find the inward predisposition of learners. Data was collected from 200 university students in Taejon and Chungnam province, Korea language learning strategies were measured by the Strategy Inventory for Language Learning(SILL), and motivation by the Attitude / Motivation Test Battery(AMTB), with adaptations for Koreans. The detailed analysis of the data Indicated that Korean university students were more motivated to learn English for a practical goal than a formal one. They had a strong willingness to learn but showed 'the tendency of the new generation' of choosing the easiest and most convenient ways in studying English in terms of motivational intensity and strategy use. Findings imply that there have to be some changes and improvements in the deep-rooted classroom teaching methods. A systematic device is needed to induce students to be autonomous learners, providing them with a variety of activities suitable for their purposes and levels, as in opportunities of contacting native speakers, multi-media language labs, the Internet etc.

  • The purpose of this study was to examine the actual state of cooking wine usage, and analyze the relationship between the attributes of cooking wine and demographic characteristics. The major findings of this study are as follows. First, the origin and correct choice of cooking wine were significantly related to hotel type, restaurant type and career. Second, the importance of the taste and aroma of a cooking wine, which are intrinsic attributes in the evaluation of a wine, had significant relationships with all the demographic variables whereas the importance of purchase cost and label information of the cooking wine only exhibited a significant correlation with career (p<0.05). Third, 53.7% of the respondents used cooking wine based on recipes, while the rest used it by rule of thumb. These results between restaurant type were significantly different (p<0.05). For the results of this research to be of more use, further research should be conducted on the functional aspects of cooking wine and their effects on cooking. In addition, further systematic research should be performed on the functional and sensory effects of a variety of wine tastes and aromas on cooking.

  • Purpose: The purpose of this study was to investigate the relationship between eating disorder, self-esteem and depression in college women. Method: Participants were 282 college women. Data were collected between Nov. 1st and 30th, 2003, and provide basic data on eating disorder levels in college women and basic data for health control programs. The instrument was a questionnaire consisting of 8 items on general characteristics and weight control, 24 on eating disorders, 10 on self-esteem and 10 on depression. Analysis of the data was done using numbers, percentages, means and standard deviations, t-test and Pearson correlation coefficients. SPSS WIN 10.0 was used in data analysis. Result: The greatest difference for eating disorders was between the group with normal body weight and the group with low body weight (t=-6.94, p=.000). There was a high positive correlation between Body Mass Index and eating disorder (r=.383, p<.01), between eating disorder and depression (r=.161, p<.01). There was a high negative correlation between eating disorder and self-esteem (r=-.196, p<.01), and between self-esteem and depression (r=-.537, p<.01). Conclusion: These results indicate that college women need more education and counseling on dietary concerns. Also, systematic efforts to establish a more health conscious social standard for beauty should be taken. Further empirical and experimental studies are required to investigate factors influencing attitudes towards eating held by college women and to determine variables which affect various specific dimensions of these attitudes.

  • This study conducted monitoring and outcome evaluation of three newly-established programs in 'Community Empowerment program in 2019' in Daegwallyeong-myeon. The purpose of the study is to find out the organic relationship between the process and result of the program and its effect on participants by performing two evaluation methods in parallel on the target program. As a result of the research, first, it was found that there was a difference in the degree of acceptance of feedback depending on the instructor who is charging each program. Second, there were two categorized results such as the depth and direction which is changed by the number of monitoring, or similar content being repeated. Third, there was an organic relationship between monitoring evaluation and outcome evaluation. Therefore, it can be said that it is highly likely to lead to more systematic and meaningful results if the community empowerment program is monitored as a process evaluation and outcome evaluation.

  • Objective: This study aimed to provide a systematic understanding of children's peer initiative and peer acceptance and to offer specific information to increase young children's social competence. Methods: Participants were 235 5-year-old children from six child care centers in Sejong City. The participants were interviewed to measure the peer acceptance of children attending the same class. Also, a survey was conducted on their teachers to measure children's peer initiative and the relationship with them. The collected data were analyzed by hierarchical regression using the SPSS 21.0 program. Results: The results showed that significant main effects of friendly and unfriendly peer-initiatives on peer acceptance were found. The effects of teacher-child relationships and their moderating effects, however, were partial; only main influences of close relationships and the interaction effects between peer-initiatives and close relationships were significant. That is, the relationships between improper initiatives and low acceptance levels among peers were more intense when children established conflict relationships with their teacher. Conclusion/Implications: We found that close teacher-child relationships play moderating roles on the pathway from peer initiative to peer acceptance as a protective risk factor for children.

  • With the increasing severity of the shortage of highly-skilled IT personnel, more and more attention is being paid to the professional career path and systematic career management of IT employees. Although some studies have been conducted to describe the current status of IT personnel, limited attempts have been made to analyze the career paths or career patterns of IT professionals from a longitudinal perspective. In this context, this study explored the job career patterns of IT professionals in Korea and examined their relationship with subjective and objective career success. To identify job career patterns over time, detailed information about jobs and positions were used and an optimal matching analysis (OMA) was conducted to calculate the dissimilarity matrix between employees' career sequences, while a cluster analysis was used to categorize the meaningful groups based on this dissimilarity data. This analysis revealed that career patterns among Korean IT personnel are more varied than previously thought. These career types have a significant relationship with individual profiles, such as age, education, industry and company size, and account for significant variations in the three main career success variables, i.e. quality of life, assessment of software quality, and wage level. It is expected that the findings of this study will contribute to refining the Korean career path so as to retain IT personnel, and raise the need to improve the low quality of life and poor SW work environment of IT personnel.
