Purpose: This study was conducted to find ways to improve foodservice quality and satisfaction of middle school students in school lunch service. Recognition of concerns about school lunch and quality attributes was evaluated by gender. And we tried to investigate quality attributes which could affect degree of foodservice satisfaction by gender. Methods: Two hundred students from each of 6 middle schools (3 schools in urban and 3 schools in rural) in Gyeonggi Province were surveyed using self-developed questionnaires. Total of 1,103 questionnaires (male 556 and female 547) were collected and data were analyzed using descriptive analysis, t-test, cross table and stepwise multiple regression by SPSS 11.0. Results: There were not significant differences in average importance scores (male 4.09, female 4.06) and average performance scores (male 3.36, female 3.30) of quality attributes between middle school boys and girls. But there were significant differences in 7 and 6 of 25 quality attributes in evaluating importance and performance respectively by gender. There was not a significant difference (male 3.13, female 3.24) in degree of foodservice satisfaction by gender. But there were significant differences in the distribution of satisfaction. Stepwise multiple regression analysis showed that degree of satisfaction was influenced by a taste of food, quick complaint handling, providing favorite foods, and food hygiene in male students (F=$51.1^{***}$, adjusted $R^2$=.265). Degree of satisfaction was influenced by a taste of food, providing favorite food, proper meal prices, providing a wide variety of food in female students (F=$91.4^{***}$, adjusted $R^2$=.399). Conclusion: We found out that there were significant differences in quality attributes when evaluating importance and performance and in quality attributes which could affect foodservice satisfaction by gender.

In this paper, we propose an adaptive K-best algorithm in which the number K of candidates is changed according to the differences of level radii. We also compare the bit error performance and complexity of the proposed algorithm with those of several conventional K-best algorithms, where the complexity is defined as the total number of candidates of which partial Euclidean distances have to be calculated. The proposed algorithm adaptively decides K at each level by eliminating the symbols, whose differences of radii are larger than a threshold, from the set of candidates, and the maximum or average value of differences can be adopted as the threshold. The proposed decoding algorithm shows the better bit error performance and the lower complexity than a conventional K-best decoding algorithm with a constant K, and also has a similar bit error performance and the lower complexity than other adaptive K-best algorithms.

Background: This study is an analysis of evaluator factors affecting physician-patient interaction (PPI) scores in clinical performance examination (CPX). The purpose of this study was to investigate possible ways to increase the reliability of the CPX evaluation. Methods: The six-item Yeungnam University Scale (YUS), four-item analytic global rating scale (AGRS), and one-item holistic rating scale (HRS) were used to evaluate student performance in PPI. A total of 72 fourth-year students from Yeungnam University College of Medicine in Korea participated in the evaluation with 32 faculty and 16 standardized patient (SP) raters. The study then examined the differences in scores between types of scale, raters (SP vs. faculty), faculty specialty, evaluation experience, and level of fatigue as time passes. Results: There were significant differences between faculty and SP scores in all three scales and a significant correlation among raters' scores. Scores given by raters on items related to their specialty were lower than those given by raters on items out of their specialty. On the YUS and AGRS, there were significant differences based on the faculty's evaluation experience; scores by raters who had three to ten previous evaluation experiences were lower than others' scores. There were also significant differences among SP raters on all scales. The correlation between the YUS and AGRS/HRS declined significantly according to the length of evaluation time. Conclusion: In CPX, PPI score reliability was found to be significantly affected by the evaluator factors as well as the type of scale.

Success in Knowledge Management depends critically on the evaluation system that managers of an organization evaluate objectively performance of members of the organization. In particular, the differences in the standard of Performance evaluation used by managers in Governmental Institution or Agency of make an issue of the standardization of Performance evaluation. Therefore, in this paper we propose the alternative evaluation method, which minimizes the bias resulted from the different standards by measuring ranking of knowledge workers, instead of quantitative analysis, using Median Rank method in Reliability and verify our proposition using the analysis of examples.

A total of 120 pigs were used to investigate the effects of yucca extracts on the growth performance, nutrient digestibility and excretion of growing pigs fed different levels of dietary protein. Pigs were allotted into $2{\times}3$ factorial design by the supplementation with yucca extract (YE, 0 and 120 mg/kg) and 3 levels of dietary protein (16, 18, 20%). During the whole experimental period (18 to 52 kg body weight), there were no significant differences in ADG, ADFI or F/G by YE addition or different protein levels among treatments (p>0.05). Overall, although addition of YE to the diet and elevation of protein level showed better ADG, there were no significant differences in growth performance among treatments. Pigs fed diets with YE showed significantly (p<0.05) higher dry matter (DM), crude ash (CA) and crude protein (CP) digestibility than did the others during the growing period. Concerning the levels of dietary protein, only the CP digestibility was significantly higher in pigs fed high protein diet. Pig fed the low protein diet without YE showed a significantly low CP digestibility (p<0.05). No significant differences were found in crude fat (CF), calcium (Ca) and phosphorus (P) digestibilities regardless of YE supplementation or dietary protein levels. Pigs fed YE supplemented diets showed significantly (p<0.05) higher amino acid digestibility. Also, high CP level diets showed a higher amino acid digestibility than low CP diets (p<0.05). DM and N excretion did not show any significant differences among treatments, there was a slightly lower excretion with increase in dietary protein level. Supplementation with YE significantly decreased the DM and N excretion. Interaction (YE$\times$protein) was found in P excretion. Pigs fed a medium protein diet without YE showed the lowest P excretion during the growing period. The NH3-N content in the feces tended to be increased by the increased dietary protein levels and with YE supplementation. During the whole experimental period, the cost for YE supplementation was similar to value of the improvements of performance obtained. The cost of feeding high level protein was significantly higher than that of medium level protein by 10% and low level protein by 9% (p<0.05). It could be concluded that the effects of dietary protein level and yucca extract on growth performance, nutrient digestibility and excretion might play a role to some extent in growing pigs from the aspect of pollution control.

Purpose : This study is descriptive correlation research aimed to examine knowledge and performance ability of cardiopulmonary resuscitation of student attending the college and provide basic materials in developing cardiopulmonary resuscitation program. Methods : Data collection was conducted with the 1st, 2nd and 3rd grade college students sampled randomly by giving them questionnaire from Sep. 1 to 4, 2008. It used the research instrument used by Choi Hyang Ok(2006) and revised and complemented by the researcher and 200 data excluding questionnaire showing unfaithful responses were used for analysis. Data collected were verified with technical statistics using SPSS/PC(version 12.0), t-test, ANOVA, and Pearson's correlation coefficient. Results : The results of this study are as follows. 1. Subjects' knowledge score of cardiopulmonary resuscitation was average .40(out of 1) and their performance ability score was average 2.39. 2. In the knowledge of cardiopulmonary resuscitation according to subjects' general characteristics, score was higher between over thirty and below twenty in age and in male subjects by sex and there were statistically significant differences(t=3.069, p=.029). 3. In the knowledge of cardiopulmonary resuscitation related to subjects' cardiopulmonary resuscitation, there were statistically significant differences in such variables as 'have you ever heard about cardiopulmonary resuscitation' (t=3.685, p=.000), 'presence or absence of education of cardiopulmonary resuscitation'(t=3.764, p=.000) and 'experience of observing cardiopulmonary resuscitation'(t=4.747, p=.000). In the performance ability of cardiopulmonary resuscitation by subjects, there were also statistically significant differences in such variables as 'have you ever heard about cardiopulmonary resuscitation' (t=2.269, p=.024), 'presence or absence of education of cardiopulmonary resuscitation' (t=3.541, p=.000) and 'experience of observing cardiopulmonary resuscitation' (t=8.118, p=,000). 4. Relation between the knowledge and the performance ability of cardiopulmonary resuscitation showed positive correlations as the more knowledge, the higher performance ability(r=.570, p=.000). Conclusion : Consequently, it was found that the knowledge and the performance ability of cardiopulmonary resuscitation by subjects were below the average and their levels of knowledge and performance ability were varied. Therefore, if 1 : 1 education with theory and practice considering knowledge and performance ability of each student in performing cardiopulmonary resuscitation education with college students is conducted, more lives can be saved by applying cardiopulmonary resuscitation not to be embarrassed when they encounter cardiac arrest case and contribute to the increase of survival of cardiac arrest patients.
