To develop the use of natural pigment for food, anthocyanins were isolated from grape peels which were wasted much in korea, and their characteristics were as fellows. pH has a marked influences on the color of the grape peels anthocyanin solution(GPAS). At low pH the color of GPAS was more stable than high pH. With increasing pH the color gradually fades as colorless pseudobases are formed. It showed characteristic bathnochromic shift as the solution increased. Among the sugars tested, glucose showed the most protective effect on the color of GPAS to raise the color stability, while fructose showed an adverse effect. Orgarnic acid such as citric acid prevented the degradation of anthocyanin, but ascorbic acid lowered stability of color considerably. The effect of light on GPAS was found to be very deleterious. The pigment degradation can be minimized by shielding the light from the pigment solution.

Purpose : The purpose of this study was to evaluate the prescription pattern of NSAIDs and GPAs in the arthritis patients over 65 years old to prevent the GI adverse events. Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most commonly used agents to treat arthritis, can cause gastrointestinal (GI) adverse effects. Recent guidelines recommend that moderate risk patients who have one or two risk factors, should be prescribed either combination of non-selective NSAID (nsNSAIDs) and gastroprotective agent (GPAs) or selective NSAID alone. Methods : Study population was National Patient Sample of 2011. Number of drugs used were 138 for NSAIDs and 21 for GPAs. Chi-square test was used to compare prescribing patterns. Results : The appropriate prescription rate follows the guideline was 11.2%: co-prescription with nsNSAID and proton pump inhibitor (PPI) or misoprostol was 1.6% and selective NSAID alone was 9.6%. Inappropriate prescription rates were as follows: co-prescription with nsNSAID and Histamine-2 receptor antagonist (H2RA) or antiacid was 53.8% and nsNSAID alone was 35.0%. The appropriate prescription rate among the types of medical institute was 54.4% in tertiary hospital, 31.2% in secondary hospital, and 6.0% in primary hospital. The appropriate prescription rate among the regions was 19.4%, highest in Seoul and 4.2%, lowest in Jeju. The appropriate prescription rate among the medical departments was as follow: 12.2% in orthopaedic surgery, 11.0% in internal medicine, and 7.7% in other departments. Conclusion : This finding suggests the needs to revise the national medical insurance imbursement policy, provide continuing medical education about the guideline of medical doctors.

Objectives : The purpose of this study is to analyze the causes of stress driven by the national examination and to find out correlation between stress factors and students' general characteristics. Methods : Data were collected from self-reported questionnaires by dental hygiene students in D university in February, 2012. Results : Those having good high school GPAs (p<.05) and high preliminary test scores (p<.01) towards dental hygienist (p<.05). National license examination was the most stressful factor for 54.2% of the students. Much more stressful pressure goes to students of non-scheduled admission (p<.01), students who graduated from vocational high schools(p<.01), students with good high school GPAs (p<.05), and having high preliminary test scores(p<.05). Most of the students tended to bear the burden on national written examination with an average of 4.17. The most difficult subject was oral biology introduction (average 4.52). Oral biology introduction was more stressful to students of early admission, students graduating from vocational high schools (p<.05), students with good high school GPAs (p<.05), and students who had relatively low preliminary test scores (p<.001). Conclusions : It is crucial to reduce stress factors and to develop related programs.

The scores of TOEFL, TOEIC, and TEPS have been increasingly used for many purposes in Korea. In particular, these test scores are being used as a predictor for determining readiness for and success in college work, or as a measure of the testees' overall English proficiency. Nonetheless, studies have rarely proposed that the validity of the test scores is used for either purpose. As a preliminary step to explore the predictive validity of the test scores, we collected the scores of TOEFL, TOEIC, and TEPS from thirty students of a university as well as their cumulative grade point averages (GPAs). The correlations between the test scores and GPAs show that TOEFL will be most likely to have the highest validity coefficient as a predictor for determining success in college work as well as a measure of overall English proficiency. Although this study has a few limitations such as the small number of participants, their homogeneousness as a group, etc., it provides some insight into the use of the three tests for college admissions and measurement of overall English proficiency and suggests need for conducting further validation studies in these areas.

Yonsei University College of Medicine is about to adopt a new admission system in 2009 for postgraduate medical school. in which 4-year college graduates apply to it, instead of applying of high school graduates to undergraduate medical school. For preparing the new system, now, an admission policy is being intensively investigated. In the present admission system in Yonsei College of Medicine, college or university graduates with diverse majors such as pharmacy, biochemistry, engineering, social science and so on other than a medical major can be transferred into the undergraduate medical course when vacancy for enrollment is available. This study was performed to analyze the academic achievement of the transferred students for establishing a new admission system. In this study, the GPAs of 94 medical students transferred for 1998 to 2006 years were analyzed regarding academic and personal background, and compared with those of untrans- ferred medical students. The results showed some features. Particularly, the GPAs of transferred students with t he majors of art and social sciences were not lower than those with the major of natural sciences while transferred students with majors of pharmacy. veterinary science, nursing science, and biotechnology had their high academic achievements during the undergraduate medical courses.

This study presents a descriptive statistical analysis on grade characteristics and employment rates of three ocean-related departments at a university. The ocean-related departments belong to the same college along with the other six departments. To obtain the correlation between the grade characteristics and employment rates, we carried out the followings. Firstly, four-year employment rates and six-semester GPAs (grade point averages) were obtained from the nine departments. Secondly, the box-and-whisker plots were constructed for each data set to capture the grade characteristics (mean, the first quartile, median, third quartile, whisker+, and Q3 box). Finally, the grade characteristics and employment rates were correlated. It is shown from the correlation analysis that the employment rate has a positive linear relation with the mean or third quartile, while the rate has a negative linear relation with the whisker+ or Q3 box, for the ocean-related departments possibly because these departments have higher regular employment rates than those of the other six departments.

On the basis of exploration for the effect of grade skipping and early graduation on socio-emotional adjustments of early college entrants, this study sought to present educational and counseling implications for the promotion of efficiency in practicing grade skipping and early graduation. Fifty-two students were asked to report their IQs and GPAs and to respond the Self-Esteem Inventory(Coopersmith, 1967, 1981, 1984) and the Attitude toward Schooling Scale(Lee & Lee, 2000). The data collected were analyzed by MANOVA and MANCOVA. On the contrary to concern for socio-emotional development of early entrants, the result indicated that there was not any statistically evidence to show the differences in socio-emotional adjustments between early entrants and the counterparts in the K University. However, there were significant group differences in attitude toward schooling(e,g,. the opportunities and informations for grads skipping and early graduation).

In this study, the steady state performance analysis program was developed for a turboprop engine, and its performance was analyzed at uninstalled and installed conditions. For the purpose of evaluation the developed program was compared with the performance data provided by the engine manufacturer and analysis results of GASTURB8.0 program. It was confirmed that the developed program was reliable because the results by the developed program were well agreed with those by GASTURB8.0 within %%. The linear and non-linear GPA(Gas Path Analysis) programs for performance diagnotics were developed, and selection of optimal measurement variables was studied. Furthermore, in order to investigate effects of the number and the kind of measurement variables, the linear and non-linear GPAs were analyzed with various measurement set. If the measurement parameters were properly selected, the reliable and economic faults detection might be possible even thought the small number of measuring parameters were used.

Linear GPA(Gas Path Analysis) and non-linear GPA programs for performance diagnostics of a turboprop engine were developed, and a study for selection of optimal measurement variables was performed. Simultaneous faults in the compressor, the compressor turbine and the power turbine, which occur damage of the engine, were assumed. The non-linear GPA analysis was carried out with an iterative method, where the performance degradation rate of independent parameters was divided into same intervals. It was compared with the result by the Newton-Raphson method for observing the effect of an iterative method. According to the analysis result, it was found that performance of non-linear GPA can be influenced on the type of the iterative method. For showing effects of the number of measurement variables both the linear and non-linear GPAs were analyzed with 10, 8 and 6 measurement sets, respectively. RMS error between them were compared each other. It was realized that the more measurement parameters are used, and the more accurate result may be obtained. However much better result can be obtained with measurement parameters selected properly Moreover, RMS error by using non-linear GPA was less than that by using linear GPA.

The purpose of this research is to examine the factors correlated with adjustment to collage life of students such as their academic achievement and college life satisfaction. This research focuses on the relationship between values and college life satisfaction based on perspectives that individual values have close affinity with life satisfaction. For analyses, we used 5-years of information of college admission and GPAs of all students, and survey data of 671 students of C university. The results are as follows; 1) academic achievement is the highest among those with comprehensive school report admission-within the enrollment quota, 2) college life satisfaction is pertaining to specific values such as belief in justice, cooperation, and trust, 3) college life satisfaction is related with the satisfaction of overall educational environment. The results emphasize the importance of education of public values to enhance adjustment to college life of students.
