On the basis of studies that show multi-word combinations, that is the field of phraseology, this study aims to examine relationship between the quality of text and phraseological competence in L2 English writing, following Yves Bestegen et al. (2014). Using two different association scores, t-score and Mutual Information(MI), which are opposite ways of measuring phraseological competence, in terms of scoring frequency and infrequency, bigrams from L2 writers' text scored based on a reference corpus, GloWbE (Corpus of Global Web based English). On a cross-sectional approach, we propose that the quality of the essays and the mean MI score of the bigram extracted from YELC, Yonsei English Learner Corpus, correlated to each other. The negative scores of bigrams are also correlated with the quality of the essays in the way that these bigrams are absent from the reference corpus, that is mostly ungrammatical. It indicates that increase in the proportion of the negative scored bigrams debases the quality of essays. The conclusion shows the quality of the essays scored by MI and t-score on cross-sectional approach, and application to teaching method and assessment for second language writing proficiency.

Recently, interests and utilization on Computed Radiography(CR) and Digital Radiography(DR) tends to increase owing to an introduction of Picture Archiving and Communication System(PACS) and an accuracy control of special medical equipment for a breast imaging examination. This study was intended to compare and analyze a detector's imaging quality by each system to be used for the breast imaging examination by using ACR Phantom used at the accuracy control. As an evaluation method, a significance and reliability of image's value using the ACR Phantom was analyzed by using SPSS program. The results are followed. 1. For the fiber, there was 3.9 score in Screen-Film, 4.2 score in CR($50{\mu}m$), 3.2 score in CR($100{\mu}m$), and 4.2 score in DR. There was the high score in the order of CR($50{\mu}m$), DR, Screen-Film, and CR($100{\mu}m$)(P<0.05). 2. For the calcification, there was 2.7 score in Screen-Film, 2.5 score in CR($50{\mu}m$), 2.0 score in CR($100{\mu}m$), and 2.9 score in DR. There was the high score in the order of DR, Screen-Film, CR($50{\mu}m$), and CR($100{\mu}m$).(0.025(P<0.05). 3. For Mass, there was 3.8 score in Screen-Film, 3.8 score in CR($50{\mu}m$), 3.6 score in CR($100{\mu}m$), and 4.5 score in DR. There was the high score in the order of DR, CR($50{\mu}m$), Screen-Film, and CR($100{\mu}m$) (P<0.1). 4. As the total score, there was 10.4 score in Screen-Film, 10.6 score in CR($50{\mu}m$), 8.7 score in CR($100{\mu}m$), and 11.3 score in DR. There was the high score in the order of DR, $CR(50{\mu}m$), Screen-Film, and $CR(100{\mu}m$). As shown in the above results, it can be known that DR and Screen-Film System has higher image quality than CR. But, DR has unstability caused by element, and Screen-Film has the low image quality caused by artifact as disadvantages. When Dual-Side CR($50{\mu}m$) was used among CR systems which had the problem of low image quality, it was indicated that there was no difference with Screen-Film System. Because the radiation imaging examination tends to become digitalized, each system for the breast imaging examination will need to be developed and supplemented.

This study aims at providing necessary informations to decide what services would be conducted preferentially in the hospital by limited resources. So this study revalued the customer's perception about the qualities of the hospital services by the Kano Model and examined the customer satisfaction coefficients suggested by Timko. The researcher conducted a survey from the patients of the 4 university hospitals in Incheon and southern Gyeonggi Province In 2008. The results of this study can be summarized as follows; It was found that the total 31 items are could be classified into 7 attractive quality elements, 22 one-dimensional quality elements and 2 indifferent quality elements, while the natural quality element wasn't found. The highest score element of the customer's satisfaction coefficients was identified as easy parking(0.69) and the lowest score item was the offer of the hospital newsletter and information about medical care(0.47). When the hospital service was not sufficient to the customer, the highest score element of the customer's dissatisfaction coefficients was proved the convenient ward and facilities(-0.75) and the lowest score item was the buses running to the entrance of the hospital(-0.32). Also it was found that the attractive quality elements appraised by the preceding study were revalued the one-dimensional quality elements. The reason was because the customer's expectation on the services was changed high, as time went by.

It is suggested that evaluation of diet quality may be a great indicator of nutritional assessment. The aim of this study was to evaluate the diet quality of children and adolescents based on nutrient and food group intake and Diet Quality Index-International (DQI-I). This survey was conducted through questionnaires and diet record survey to 477 students (elementary school students; n = 131, middle school students; n = 136, and high school students; n = 210). The results showed that high school students were significantly more often to skip breakfast compared with the other groups. The middle and high school students consumed significantly higher intakes of food and energy compared to the elementary school students. Also the number of nutrients in Index of Nutritional Quality (INQ) < 1.0 of high school students were significantly higher than that of elementary and middle school students. The Korean's dietary diversity score (KDDS) of elementary school, middle school and high school students were 4.1, 4.4 and 4.3 respectively. The average DQI-I of elementary school, middle school and high school students were 66.7, 65.5, and 63.7, respectively and there was significant difference. Also, middle school students showed to have higher score in variety and adequacy category compared with the other groups, and elementary school students appeared to have higher score in moderation category. In conclusion, high school students appeared to have unhealthy dietary habits in terms of high frequency of skipping breakfast and lower INQ and DQI-I score compared to the elementary school and middle school students. Therefore, the proper dietary management should be needed for high school students.

This research discusses the characteristics and the implementation strategies for two types of quality metrics to analyze innovation effects in six sigma projects: fixed specification type and moving specification type. $Z_{st}$, $P_{pk}$ are quality metrics of fixed specification type that are influenced by predetermined specification. In contrast, the quality metrics of moving specification type such as Strictly Standardized Mean Difference(SSMD), Z-Score, F-Statistic and t-Statistic are independent from predetermined specification. $Z_{st}$ sigma level obtains defective rates of Parts Per Million(PPM) and Defects Per Million Opportunities(DPMO). However, the defective rates between different industrial sectors are incomparable due to their own technological inherence. In order to explore relative method to compare defective rates between different industrial sectors, the ratio of specification and natural tolerance called, $P_{pk}$, is used. The drawback of this $P_{pk}$ metric is that it is highly dependent on the specification. The metrics of F-Statistic and t-Statistic identify innovation effect by comparing before-and-after of accuracy and precision. These statistics are not affected by specification, but affected by type of statistical distribution models and sample size. Hence, statistical significance determined by above two statistics cannot give a same conclusion as practical significance. In conclusion, SSMD and Z-Score are the best quality metrics that are uninfluenced by fixed specification, theoretical distribution model and arbitrary sample size. Those metrics also identify the innovation effects for before-and-after of accuracy and precision. It is beneficial to use SSMD and Z-Score methods along with popular methods of $Z_{st}$ sigma level and $P_{pk}$ that are commonly employed in six sigma projects. The case studies from national six sigma contest from 2011 to 2012 are proposed and analyzed to provide the guidelines for the usage of quality metrics for quality practitioners.

The fat mass and obesity associated (FTO) gene plays an important role in the regulation of energy homeostasis, fat deposition and obesity. For this reason, the FTO gene is a physiological and functional candidate gene for carcass and meat quality traits in beef cattle. The objectives of this study were to identify SNPs in the exonic regions of FTO gene and to evaluate the association of these SNPs with carcass traits in Hanwoo (Korean cattle). In this study, we newly identified two exonic SNPs in Hanwoo population. The g.125550A > T SNP was located in exon 3 and the g.175675C > T SNP was located in exon 6. Genotyping of the two SNP markers was carried out using PCR-RFLP analysis in Hanwoo steers to evaluate their association with carcass traits. As a result, g.125550A > T SNP genotype was significantly associated with effects on marbling score. Animals with the AA and TT homozygous genotypes had a significantly higher marbling score (p < 0.001) than those with AT heterozygous genotype, and this was significant after Bonferroni correction of the significance threshold (p = 0.003). Dominance effect was also observed for the marbling score (P < 0.05) with higher marbling score of homozygous animals. However, no significant associations with meat quality traits were observed for the g.175675C > T SNP. Our results suggest that the exonic SNP g.125550A > T in the FTO gene may be used as a DNA marker for the selection of Hanwoo with higher marbling.

Purpose: The purpose of this study was to examine the association between health behaviors and health-related quality of life (HRQOL) among vulnerable children in a community. Methods: Using data from 'The Obesity Prevention Framework for Vulnerable Children', a secondary analysis was conducted for 165 children (ages 8~12 years) and their parents who were recruited from 16 K-gu Community Child Centers in Seoul. Six types of health behaviors related to eating and activity were assessed. Each behavior was categorized into the non-recommended vs. recommended levels. The scores of the recommended levels of the six health behaviors were summed up for the composite score of health behaviors. HRQOL was measured by KIDSCREEN-52. Results: The groups with a non-recommended level of fast food intake and sedentary behavior had a significantly lower total score of KIDSCREEN-52 than those with a recommended level. Moreover, the lower composite score of health behaviors was significantly associated with the lower total score of KIDSCREEN-52. Conclusion: Among the vulnerable children, the six recommended health behaviors and their composite score were in significant positive associations with the HRQOL levels. Therefore, nursing strategies for enhancing the recommended levels of health behaviors are needed for vulnerable children.
