This study was to evaluate the taste of the wine assessment gap analysis to compare the taste of the wine intended for college student wine consumers and wine experts. Research analysis was carried out frequency analysis to the strength of the wine taste a difference in the intensity of the consistency review and wine for the wine flavor between the two groups. According to result, red wine, bitter and salty taste was perceived higher. For white wines are perceived sweetness of wine was sour and higher consumer groups. Body was found that wine experts perceive higher. The Second difficulty is when college student wine consumers selected wine got another show to the lack of information, lack of expertise, price, taste, the combination of food. Another wine on difficult points during the wine expert wine recommendations wine selection, price, prejudices then guest it showed a preference and communication, considering that the customer's budget, customer preferences, taste and aroma, the combination of the food and the customer response was configured. Although the criteria have different tastes for wine through college student wine consumers if future studies presented by symbolic reference to the wine tasting, can be self-objectification of subjective criteria subjective wine experts are wine consumers to take advantage of these data.

The Korean version of the Child Development Inventory (K-CDI) is a developmental screening test for children functioning in the one-six year range. Based on parent-report, the inventory assesses child developmental functioning in the areas of social, self-help, gross motor, fine motor, expressive language, language comprehension, letter and number skills, general development, and various symptoms and behavior problems. Participants were recruited from childcare centers and private groups and finally 1,143 children and their mothers from 4 locations nationwide participated in this study. Through analysis of item response rate of 270 items in 9 areas, new norm was formed. Reliability determined by internal consistency were relatively high (Cronbach ${\alpha}=.95$). Intercorrelations among sub-scales (range: .49-.96) indicated the construct validity, and the correlation between K-CDI and other screening tests supported the concurrent validity.

We have developed 10 μmol/mol nitrogen and oxygen certified reference materials (CRMs) in helium, as a SI-traceable gas standard for a quantifying of impurities in pure gases for the first time in Korea. The standard gas mixtures of nitrogen and oxygen were prepared in 5000 μmol/mol and sequentially were diluted to 250 μmol/mol and 10 μmol/mol according to the gravimetric preparation. In each dilution step, two cylinders of CRMs were prepared. The verification of internal consistency among the prepared gas mixtures was performed by using GC-TCD. The amount fractions and those expanded uncertainties (k = 2) of nitrogen and oxygen in the standard gas mixtures were (10.12 ± 0.08) μmol/mol and (10.18 ± 0.08) μmol/mol for nitrogen, and (9.88 ± 0.06) μmol/mol and (9.94 ± 0.06) μmol/mol for oxygen, respectively. We have conducted a purity assessment of two commercial helium gases using developed CRMs. As the results of the purity assessment, nitrogen and oxygen were detected by (1.66 ± 0.03) μmol/mol and (0.31 ± 0.02) μmol/mol, respectively, as the impurities in one of the pure helium.

The use of attitude as a psychological concepts dates back to 1918(Thomas and Znaniecki). Assessment of attitudes has been conducted by a number of researchers since then in a wide range of contexts: religion, government, industry, community interrelations, and education; and sociology and psychology. In science, the number of research summaries and meta-analyses points to the significance of the concept of attitude toward science. However, in spite of the wide spread use of attitude assessment in science, many of the existing instruments have severe limitations. Those limitations serve as the rationale for the construction of a new instrument to assess attitudes toward science The term "attitude" and "science" are somewhat ambiguous, taking on different meanings for different people in different contexts. Very often an assessment includes several dimensions of attitude and, therefore, provides no clear idea of what was really measured. As a result there is no consistency with respect to the construct among attitude instruments. To clarify this issue, Gauld(1982), Munby(1983a, 1983b), Blosser(1984) and Haladyna and Shaughnessy(1982) offer some guiding descriptions. Attitude as it relates to science is divided into two areas-scientific attitude and attitude toward science. Scientific attitude refers to a particular approach a person assumes for solving problems, for assessing ideas and information, and for making decisions. It includes such scientific methods and predispositions as objectivity, suspended judgement, critical evaluation, and skepticism. Munby(1983a, 1983b) characterized scientific attitude as thinking as scientists do, that is, acting on evidence in a disciplined way. Attitude toward science. on the other hand, may address scientific attitudes, scientists, scientific careers, methods of teaching science, scientific interests, parts of curriculum, or the subject of science in the classroom (Blosser,1984). It may refer to belief about processes, theoretical products, technological products, or the science-technology relationship (Munby, 1983).

Introduction: The importance of clinical skills training in traditional Korean medicine education is increasingly emphasized. Since the clinical skills tests are high-stakes tests that determine success in national licensing exams, it is essential to develop reliable multifaceted analysis methods for clinical skills tests in actual education settings. In this study, we applied the multifaceted validity evaluation methods to the evaluation results of the cardiopulmonary resuscitation module to confirm the applicability and effectiveness of the methods. Methods: In this study, we used internal consistency, factor analysis, generalizability theory G-study and D-study, ANOVA, Kendall's tau, descriptive statistics, and other statistical methods to analyze the multidimensional validity of a cardiopulmonary resuscitation test in clinical education settings over the past three years. Results: The factor analysis and internal consistency analysis showed that the evaluation rubric had an unstable structure and low concordance. The G-study showed that the error of the clinical skills assessment was large due to the evaluator and unexpected errors. The D-study showed that the variance error of the evaluator should be significantly reduced to validate the evaluation. The ANOVA and Kendall's tau confirmed that evaluator heterogeneity was a problem. Discussion and Conclusion: Clinical skills tests should be continuously evaluated and managed for validity in two steps of pre-production and actual implementation. This study has presented specific methods for analyzing the validity of clinical skills training and testing in actual education settings. This study would contribute to the foundation for competency-based evidence-based education in practical clinical training.

Background: The Work Ability Index (WAI) is an instrument that measures work ability. The wide dispersion of the WAI internationally has led to its adaptation for use in different countries. This study aimed to evaluate the psychometric properties of the Spanish version of the WAI. Methods: A methodological design was used over an opportunistic sample of 233 workers in the aeronautical industry in Spain. Reliability was evaluated through internal consistency. Factorial validity, known groups, and convergent validity were tested. Results: The Cronbach's alpha and item-total correlation indicated an adequate internal consistency. The confirmatory factor analysis, performed to evaluate the factorial validity, found adequate fit indices for a two-factor solution with a high correlation between the factors. Factor 1, "Subjectively estimated work ability and resources", was composed of 3 subscales and factor 2, "Ill-health-related", of 2 subscales. Subscales 4 and 6 had loading in both factors. Workers under 45 years of age obtained higher significant scores than older ones. Convergent validity was also evidenced since WAI was highly correlated with self-assessment of health status. Conclusions: The Spanish version of the WAI has shown evidence of reliability and validity in this study, supporting its use in individual and collective health surveillance by occupational health professionals. The factorial solution that was found has previously been reported in another international context. However, further research is needed to resolve the discrepancies detected in the role of some subscales between other national and international studies.

Purpose: Rome criteria are considered the gold standard for diagnosing functional constipation. The modified Bristol stool form scale (m-BSFS) was validated to measure stool form in children. However, neither the potential use of the m-BSFS as a tool to facilitate the diagnosis of potential constipation, nor the agreement between m-BSFS and stool consistency by Rome has been studied. Our objective is to determine if m-BSFS is a reliable tool to facilitate detection of constipation; and the agreement between stool form by m-BSFS and hard stool criteria in Rome. Methods: A survey tool with the Rome III criteria and the m-BSFS was developed. A Likert-scale addressed frequency of each stool form on the m-BSFS. Responses to Rome III and m-BSFS were compared. Results: The sensitivity and specificity of the m-BSFS was 79.2% and 66.0% respectively; and in children <4 years. improved to 81.2% and 75.0% respectively. There was poor agreement between hard stools by m-BSFS and the painful or hard bowel movement question of Rome Criteria. Conclusion: The potential utility of m-BSFS as a reasonably good tool to facilitate the diagnosis of potential constipation in children is shown. The poor agreement between painful or hard stool question in Rome III, and ratings for hard stool on the m-BSFS illustrates that one's perception may differ between a question and a picture. A useful pictorial tool to appraise stool form may, thus, be a favorable complement in the process of enquiry about bowel habits in well-child care.
