Purpose: The purpose of this study was to determine reliability and validity of the Postural Assessment Scale for Stroke Patients (PASS) in chronic stroke patients. Methods: A total of 43 stroke patients, who had a stroke more than 6 months previously, participated in the study. Reliability was determined by the intra-class correlation coefficient (ICC$_{3,1}$), Bland and Altman method and Cronbach's alpha by internal consistency. Validity was examined by correlation the PASS scores to the Berg Balance Scale (BBS), Trunk Control Test (TCT), and Fugl-Meyer Balance (FM-B) score. Results: The intra-rater reliability and the Absolute reliability of the PASS was good ICC$_{3,1}$=0.97 (95%CI 0.95$\sim$0.99) and excellent SEM=1.01 respectively. Cronbach's alpha value for PASS was found to be 0.94. There were significant correlations between the PASS and BBS, TCT, FM-B (r=0.65－0.96, p<0.01). Conclusion: The PASS provide reliable and valid instrument of the postural control assessment for chronic stroke patients.

Mg-Cu composites were successively fabricated using a combination of rapid solidification and extrusion processes. In addition, the microstructural variation of the composite was investigated by performing the extrusion repeatedly. It resulted that the composite formed an uniform and dense structure by the extrusion, and the microstructure became fine as the extrusion conducted repeatedly. The microstructural variation was known to be dependent on the number of extrusion and the area reduction ratio. The tensile strength was also measured as a function of the microstructural variation.

The Incoterms, short for "International Commercial Terms," have been widely used as International Rules for the Interpretation of Trade Terms since 1936. The Incoterms have been revised six times in order to adapt them to contemporary commercial practice. The current version is Incoterms 2000. The revised version of Incoterms 2000 will be published in the fourth quarter of 2010 and will be effective from January 1st 2010. The first and second draft of Incoterms 2010 have been carried out by a small global Drafting Group, representing seven nationalities and various areas of substantive expertise. In this paper, I reviewed the main contents in the 2nd Draft of Incoterms 2010. This paper contributes to help the parties concerned to understand the new changes from Incoterms 2000 and to choose the appropriate trade term.

INCOTERMS have been changed almost every 10 years since ICC established INCOTERMS as trade terms for International transaction. Recently transportation has become bigger, and modernized by means of electronic appliances such as RFID, IT, and containerization. FRC, FOR/FOT, FOA were added in INCOTERMS1980 and every conditions are unified into three alphabets in INCOTERMS1990. The best features of INCOTERMS2000 are that FCA substitute FRC, FOR/FOT, FOA and customs formalities were simplified to make clear for each party of contract. It seems that business circles still stick to old customs of their trade like FOB or CIF not only in Korea but in an international practice even though there have been several revisions of INCOTERMS until now. ICC have tried to provide INCOTERMS3000 to solve problems between a theory and an actual condition of international trade. This study has tried to suggest opinions against INCOTERMS3000 and has surveyed a recognition, an actual using situation and issues of INCOTERMS to get improvements. For a recognition of INCOTERMS has been spread as you can find at tables many kinds of business circles still stick to old customs of their trade terms FOB and CIF. Now there are two alternative plans. Firstly, we need to suggest improvements against inconsistency of INCOTERMS to be applied on newly revised INCOTERMS3000 and educating business circles to use proper conditions of INCOTERMS for their doing business. Secondly, we shall participate in revising INCOTERMS to activate multimodal transport conditions of INCOTERMS and provide solutions to fill gap between a theory and an actual condition of international trade. It seems that terms of multimodal transport such as FCA, CPT, or CIP can be a perfect condition for each party of contract. We have examined the inconsistent features of Ship's rail and notions of on board, and observed how to activate multimodal transport terms. These would be hot issues of next revision of INCOTERMS and we provided improvements on each trade terms, THC charges, or others against INCOTERMS.

The color reproduction of digital still camera does not, in general, match those of the final output device. Because color gamut of these devices is different, it is therefore necessary to take account of a way to match. The way uses the optimized profile to output device an image. This paper proposed a way to create the input profile of digital still camera for standardization soft proofing process. The results of proposed way showed that for input profiles equivalent, good results relatively. In this paper, an experiment was done where the illumination sources used as the standard illumination 5200K and illuminated at a $45^{\circ}$ angle in the best illumination efficiently. The white balance was in mode 'custom' : aperture F11, exposure time 1/60s, ISO50, focal length 80mm. The images were exported and saved as 16bit RGB TIFF(AdobeRGB, sRGB, ProphotoRGB) images. To do the test, the RGB values of the RGB TIFF images are processed through the ICC input profile to arrive at processed $CIEL^*a^*b^*$ values. A profiling tool such as ProfileMaker 5.0 and Monacoprofile 4.8 are used to do this. The processed $CIEL^*a^*b^*$ values are compared to the reference $CIEL^*a^*b^*$ values and these two values are used to calculate a ${\Delta}E{^*}_{ab}$.

The purpose of this study was to determine the reliability and validity of the fear-avoidance beliefs questionnaire (FABQ) in assessing Korean patients with low back pain. We performed translation and cross-cultural adaptation of the questionnaire and enrolled 52 patients (18 males and 34 females) with low back pain. The subjects completed a standardized self-administered questionnaire that included the FABQ assessment along with evaluations for the visual analogue scale (VAS), Oswestry disability index (ODI), self-rating anxiety scale (SAS), and Beck depression inventory-Korean version (K-BDI). The reliability of the obtained data was determined by evaluating the internal consistency on the basis of the intraclass correlation coefficient (ICC) and the Cronbach's alpha values, while the validity of the data was examined by correlating the FABQ scores to the VAS, ODI, SAS, and K-BDI scores. The translated versions of the FABQ showed good test-retest reliability: ICC (3, 1)=.90 (FABQ for physical activity) and .97 (FABQ for work) these values were statistically significant (p<.01). The Cronbach's alpha value for FABQ was .90 (p<.01). FABQ moderately correlated with pain, disability, anxiety, and depression (p<.01). The results of this study indicate that the Korean version of the FABQ is a reliable and valid instrument for measuring fear-avoidance beliefs in Korean patients with low back pain.

Purpose: The purposes of this study were to determine the intertester and intratester reliabilities of the Lateral Scapular Slide Test (LSST) method, and to examine if significant differences existed in scapular positions among the pain groups (right-shoulder pain group, left-shoulder, pain group and both-shoulders pain group). 27 female subjects (mean age = 51.6, mean height = 157.7 cm, mean weight = 57.5 kg) with shoulder pain were recruited for this study. Methods: The bilateral distances between the root of the scapular spine and T3/4 (RSS), and between the inferior scapular angle and T7/8 (IA), were recorded. Subjects were tested at three positions: the with arms with abducted at 0, 45 and 90 degrees in the coronal plane. The LSST measurements were performed by two testers, selected randomly. Results: The results were as follows: Intraclass correlation coefficients (ICCs) for the intertester reliability were excellent (ICC 0.78-0.94). And the ICCs for the intratester reliability were excellent (ICC 0.83-0.99). In the right-shoulder and both-shoulders pain groups, the right-side RSS and IA values of right side were significantly greater than of the left-side RSS values left side for the arms abducted at 0 degrees of right shoulder pain group and both shoulder pain group (p<.05). However, the side-to-side difference was less than 1.5 cm. Conclusion: Our results suggest that the LSST is highly reliable in identifying the abnormal scapular position of patients with shoulder problems. Future research should be continued to clarify the clinical usefulness of this method.

Objectives: Exposure assessment is a major challenge faced by studies that evaluate the association between pesticide exposure and adverse health outcomes. The objective of this study was to investigate the reliability of information that farmers self-report regarding their pesticide use. Methods: Twenty five items based upon existing questionnaires were designed to focus on pesticide exposure. In 2009, a selfadministrated survey was conducted on two occasions four weeks apart among 205 farmers residing in Gyeonggi and Gangwon provinces. For a reliability measure, we calculated the percentage agreement, the kappa statistics and the intraclass correlation coefficient (ICC) between the two reports according to the characteristics of the subjects. Results: Agreement for ever-never use of any pesticide was 96.4% (kappa 0.61). For both 'years used' and 'age at the first use' of overall pesticides, high agreement was obtained (ICC: 0.88 and, 0.78, respectively), whereas those of 'days used' and 'hours used' were relatively low (ICC: 0.42 and, 0.66, respectively). The kappa value for the use of personal protective equipment ranged from 0.46 to 0.59, and hygiene activities came out at 0.19 to 0.37. The agreement for individual pesticide use ranged widely and there was relatively low agreement due to the low response rates. The reliability scores did not significantly vary according to gender, age, the education level, the types of crop or the years of farming. Conclusions: Our results support that carefully designed, self-reported information on ever-never pesticide use among farmers is reliable. However, the reliability of data on individual pesticide exposure may be unstable due to low response rates and needs to be refined.

Generally, if RGB image is sent to the printer when we print a digital photograph, the printer will convert RGB to CMYK by the inner built-in drive. Because the difference between color domain of RGB and CMYK will cause that change and difference. The most common way to solve the problem is to convert colors by using ICC profile at RIP software or to adapt automatic color converting from the software of the original printer. So we intended to study show which way is most efficient to the digital output and which color mode device is the best based on the printer's own drive in this paper. we tried to observe and check the extended range of color space such as AdobeRGB as well as CMYK and sRGB. Then we made sure which is the suitable color space. Besides, When we convert RGB mode into CMYK mode by utilizing RIP software and adapt the printer's ICC profile made by our selves, we evaluated the output we get and compared the result with extended RGB image. The results are as follows. In case of RGB mode, the printer requests RGB, and that makes the color space more efficient than CMYK's. Converted to CMYK by utilizing RIP software, the chroma is more linearized than the one produced with its' own driver. Compared with sRGB mode's color gamut, AdobeRGB mode's color gamut and CMYK mode's color, CMYK mode's color gamut is the smallest among 3 of them. CMYK mode's color gamut by utilizing RIP software can be changeable. that can be small and narrow or wide and broad. In other words, the volume of color gamut depends on how CMYK is linearized. The color space of sRGB is more advantageous than the one of AdobeRGB in color-reproduction printed. But in the group $-b^*$, the chroma leaves behind in terms of reproduction, In the group of $-a^*$, the chroma is excellent relatively. Visual evaluation of the image, AdobeRGB image has not many reproduction colors. Specially, according to printers' characteristics, Group B of AdobeRGB and sRGB color space is a long way behind In terms of reproduction but Group Y is excellent relatively.

It has been known that bus route and company related characteristics have influences on punctuality, but fewer research have been conducted. Independent variables used in this study were selected using correlation analysis, and OLS(Ordinary Least Square) and HLM(Hierarchical Linear Model) were employed to identify factors affecting bus punctuality(headway deviation). The results showed that ICC(intraclass Correlation Coefficient) is 0.10, indicating that hierarchical linear models are more adequate for these data because there is effective variation in the subjects between companies. Punctuality was found to be negatively associated with the number of vehicles, the number of persons per vehicle, and total travel time. On the other hand, average headway and company size have a positive relationship with punctuality. Therefore, the number of vehicles per route, average headway, and the number of vehicles managed by a company should be considered for more accurately evaluating the management of piunctuality.
