In this study, we analyzed the gene expression data of Saccharomyces cerevisiae obtained from Holstege et al. 1998 to understand the relationship between expression level and nucleotide sequence of a gene. First, the correlation between gene expression and percent composition of each type of nucleotide was computed. It was observed that nucleotide 'G' and 'C' show positive correlation (r ${\geq}$ 0.15), 'A' shows negative correlation (r ${\approx}$ -0.21) and 'T' shows no correlation (r ${\approx}$ 0.00) with gene expression. It was also found that 'G+C' rich genes express more in comparison to 'A+T' rich genes. We observed the inverse correlation between composition of a nucleotide at genome level and level of gene expression. Then we computed the correlation between dinucleotides (e.g. AA, AT, GC) composition and gene expression and observed a wide variation in correlation (from r = -0.45 for AT to r = 0.35 for GT). The dinucleotides which contain 'T' have wide range of correlation with gene expression. For example, GT and CT have high positive correlation and AT have high negative correlation. We also computed the correlation between trinucleotides (or codon) composition and gene expression and again observed wide range of correlation (from r = -0.45 for ATA r = 0.45 for GGT). However, the major codons of a large number of amino acids show positive correlation with expression level, but there are a few amino acids whose major codons show negative correlation with expression level. These observations clearly indic ate the relationship between nucleotides composition and expression level. We also demonstrate that codon composition can be used to predict the expression of gene in a given condition. Software has been developed for calculating correlation between expression of gene and codon usage.

Hearing impairment children possess poor underlying perceptual knowledge of the sound system and show delayed development of segmental organization of that system. The purpose of this study was to investigate the relationship between phonological awareness ability and word identification ability in hearing impaired children. 14 children with moderately severe hearing loss participated in this study. All tasks were individually administered. Phonological awareness tests consisted of syllable blending, syllable segmentation, syllable deletion, body-coda discrimination, phoneme blending, phoneme segmentation and phoneme deletion. Close-set Monosyllabic Words(12 items) and lists 1 and 2 of open-set Monosyllabic Words in EARS-K were examined for word identification. Results of this study were as follows: First, from the phonological awareness task, the close-set word identification showed a high positive correlation with the coda discrimination, phoneme blending and phoneme deletion. The open-set word identification showed a high positive correlation with phoneme blending, phoneme deletion and phoneme segmentation. Second, from the level of phonological awareness, the close-set word identification showed a high positive correlation with the level of body-coda awareness and phoneme awareness while the open-set word identification showed a high positive correlation only with the level of phoneme awareness.

PURPOSE: This study measured the external pressure on abdomen during maximal inspiration. The study determined the correlation between the diaphragmatic contraction pressure and the lung capacities to verify whether or not the measured pressure values can represent diaphragmatic contractility. METHODS: The study included 32 healthy subjects (16 males and 16 females). The researchers fabricated their own diaphragmatic pressure belt (DiP Belt) to measure DCP. DiP Belt device was fixed on the front of the abdomen and the diaphragmatic contractility was measured during maximal inspiration. The lung capacities were measured using a portable digital spirometer device (Pony Fx, COSMED, Italy). A digital spirometer is a device that is used to test the flow of air entering and exiting the lungs. RESULTS: DCP showed significant positive correlations with vital capacity (VC), inspiratory reserve volume (IRV) and inspiratory capacity (IC). Among values of lung capacities, IC showed especially strong positive correlations with the DCP (r =.714, p<.010). For the males, DCP showed significant positive correlations with IRV and IC, and DCP showed significant negative correlation with the expiratory reserve volume (ERV). For the females, DCP showed significant positive correlation with tidal volume (VT), but any significant correlation was not found with any of the other values of lung capacities. CONCLUSION: DCP showed high correlations with IRV and IC associated with inspiratory capacity. Therefore, The DiP Belt can be looked upon as a simple device that is very useful for measuring diaphragmatic contractility.
The purpose of this study was to analyze the effects of children's self-esteem on their school adjustment, focusing on the mediation of peer attachment. A total of 2,200 3rd grade children from the third Korea Child-Adolescent Panel Survey participated in this study. The instruments used in this study were the Self-esteem Scale, Peer Attachment Scale, and School Adjustment Scale. The collected data were analyzed by using a Student's t -test, Pearson's partial correlation, simple regression, and hierarchical multiple regression with SPSS ver. 16.0 software. The main results of this study are as follows: first, the boys had higher self-esteem, peer attachment, and school adjustment scores than the girls. Second, there was a significant positive correlation between children's self-esteem and peer attachment as well as a significant positive correlation between children's self-esteem and school adjustment. Further, there was a significant positive correlation between children's peer attachment and school adjustment. Finally, children's self-esteem exerted positive effects on their peer attachment, and children's peer attachment had a positive influence on their school adjustment. The effect of children's self-esteem on their school adjustment was partially mediated by their peer attachment. These findings provide preliminary evidence that the relationships between children's self-esteem and school adjustment may be mediated by their peer attachment.

Purpose : Bridging exercise was used most frequently of lumbar stabilization exercise. There has been no reserch regarding the bridging exercise according to hip abductor activation or hip adductor activation. The purpose of this study is to determine correlation of hip abductor, adductor and abdominal muscles, lower limb muscle. Methods : Participants who met the criteria for this study (n=45). Participants performs bridging exercise on three types (normal bridging exercise, bridging exercise with hip abductor contraction, bridging exercise with hip adductor contraction) for evaluate correlation of each muscles. Results : There was a significant negative correlation between adductor magnus and gluteus medius, adductor magnus and rectus femoris. And there was a positive correlation between gluteus medius and rectus femoris on normal bridging exercise (p<0.05). There was a significant positive correlation between adductor magnus and gluteus medius, transverse abdominis, and between gulteus medius and transverse abdominis on bridging exercise with adductor magnus activation (p<0.05). There was a significant positive correlation between adductor magnus and gluteus medius, rectus femoris, and between gulteus medius and rectus femoris on bridging exercise with gluteus medius activation (p<0.05). Conclusion : When we perform bridging exercise for transverse abdominis activation and increase pressure in the abdmen, bridging exercise with hip adductor contraction is more effective than normal bridging exercise and bridging exercise with hip abductor contraction.
This study was conducted to investigate correlation theory of planned behavior, self efficacy and health locus of control about smoking cessation behavior for university student. We sampled 204 university student smokers using questionnaires and analyzed the data using Pearson correlation coefficient. The results of this study were as follows : 1. There were significant positive correlation between theory of planned behavior(intention : r=.215, p=.005, attitude : r=.160, p=.025, perceived behavior control : r=.298, p=.000) and self efficacy. 2. There were significant positive correlation between theory of planned behavior(attitude : r=.228, p=.002) and internal health locus of control. There were significant positive correlation between theory of planned behavior(attitude : r=.203, p=.004, subjective norm : r=.141, p=.047) and external health locus of control. There were significant negative correlation between theory of planned behavior(perceived behavior control : r=-.152, p=.034) and accidental health locus of control. This study has shown a correlation between theory of planned behavior and self efficacy and health locus of control. As a result of these findings, I suggest to develop the intervention program for smoking cessation.

This study investigated the correlation between learners' psychological and social factors and their syntactic complexity of speaking. The study collected samples of Korean spoken production of 61 learners with English, Chinese, Japanese and other L1 backgrounds and applied mini-TOPIK, mini-AMTB, and SASIQ for 70 minutes. The study found that: (i) integrative motivation showed positive correlation with a number of simple complex clauses, but instrumental motivation correlated negatively with a number of adverbial clauses, indicating that high motivation hindered producing highly complex clauses although it triggered producing simple complex clauses, (ii) social contact with L2 native speakers showed positive correlation with general L2 development and a number of simple complex clauses, but revealed negative correlation with double or triple complex clauses, (iii) hours of L2 listening showed very strong positive correlation with producing triple complex clauses and general proficiency, but indicated negative correlation with a number of simple complex clauses. The study reported that high motivation toward Korean learning and active social activities with Korean native speakers helped produce simple complex clauses while hours of listening to Korean helped produce triple complex clauses.
Objectives : The purpose of this study was to correlation between the index of dental caries in primary teeth and the habits of diet and snack which are expected to influence on the index. The subjects of this study were 165 parents of the children who visited a pediatric dental hospital located in Gyeong-gi do from Jun. 15th to Sep. 26th, 2009, and the self-report questionnaire survey was performed. Methods : A questionnaire used in a previous study was revised and completed for this study and it consisted of 15 items on general characteristic, nine items on dietary habit, and five items on snack intake habit. The collected data was analyzed using SPSS program and findings are as follows Results : 1. The index of dental caries in primary teeth by ages was that children of four years old has 4~5 with 27.5%, children of five years old has 2~3 and 4~5 with 33.3% and children of six years old has 1 and 8~9 with 25.6%, showing a statistically significant(${\chi}^2$=37.72, p<.01). 2. The frequency of brushing teeth was found to have statistically significant negative correlation with the number of primary teeth with dental caries (${\chi}^2$=61.20, p<.001). 3. The frequency of taking snack was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=51.42, p<.001). 4. The desirability of dietary habit was found to have statistically significant negative correlation with the number of primary teeth with dental caries (${\chi}^2$=36.51, p<.001). 5. The frequency of taking biscuit was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=67.74, p<.001). 6. The frequency of taking bread was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=29.63, p<.01). 7. The frequency of taking caramel and candy was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=38.85, p<.001). 8. The frequency of taking soft drinks was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=52.92, p<.001). 9. The frequency of taking ice-creams was found to have statistically significant positive correlation with the number of primary teeth with dental caries (${\chi}^2$=75.07, p<.001). Conclusions : Those findings show that the children with undesirable dietary habit and higher frequency of taking snack have higher index of dental caries in primary teeth, therefore, it is considered that the regular brushing teeth and establishment of desirable dietary habit are very important for keeping health oral cavity. It is recommended that the continuous concern and repeated learning are needed in house and group of rearing infants so that the children take foods of fruits which have function of self-purification than the food of carbohydrates which has high adhesion and level of sweetness.
Crude fiber, ash and crude fat in various parts of root had highly significant correlation each other.

Consistently delivering good service quality is a complex and dynamic process. In this matter, service differs from tangible products and is highly dependent on the business and service provider. Therefore, efficiently managing the process of delivering service quality can contribute to profits for organization and satisfaction to customers. This study was performed to define service quality, and to investigate the personal and operational characteristics that impacts the service quality provided by foodservice provider. The responses from 278 foodservice providers and 427 customers in 82 fast-food and family restaurants were used in this analysis. Descriptive, Factor Analysis, T-test, ANOVA, and Correlation Analysis were used for statistical Analysis. The Results of this study were as follows : 1) The perception of foodservice provider was significantly higher than that of the customers in most of the 21 service quality attributes. 2) The 6 dimensions derived from Factor Analysis explained 56.8% for service quality. 3) Among the personal characteristics of the foodservice provider, the level of education and the position in the job led to a significant difference in some of the service qualities. 4) The type of restaurant played an important role in foodservice providers'perception of service quality. 5) Month since opening had a negative correlation with 'Atmosphere' and a positive correlation with 'Reputation', while the number of seats showed a positive correlation with 'Atmosphere' and a negative correlation with 'Food'and 'Convenience'. 6) In general, the characteristics of sales had a positive correlation with service quality. 7) The proportion of part-time employees showed a negative correlation with 'Atmosphere' and 'Food', and a positive correlation with 'Reputation'.
