1. Objectives : This study aimed to assessing the reliability of questionnaire for Japanese as one of method to diagnose Sasang Constitution and evaluating the possibility of applying domestic questionnaire to foreign site. 2. Methods : A cross-sectional survey approved by IRB (Independent Review Board) at Tohoku University was performed for 119 participants with informed consent at a particular city in Japan using self-reported questionnaires developed by KIOM (Korea Institute of Oriental Medicine). Among the entire samples, 112 were retested. The test-retest reliability was assessed by Kappa for normal variables and internal consistency was evaluated by Cronbach's alpha. 3. Results : Four of 77 questions are impossible to calculate consistency owing to unsymmetric matrix between primary reply and secondary one. Seventeen of them (22%) showed 0.4 or below in Kappa, 56 were ranged from 0.4 to 0.8 and no question marked 0.8 or over. Internal consistency was possibly checked for several questions about character, digestion, sweat, excrement, urine, cold-heat pattern. Cronbach's alpha for questions except urine and cold-heat pattern was over 0.6 4. Conclusions : On the basis of Kappa value by two self reported questionnaire, 72.7% of questions showed 0.4 or over so that reliability were highly secured. And other questions except for urine and heat-cold pattern marked 0.6 or over in order that internal consistency was also successfully maintained. Accordingly, when subsequently applying KIOM questionnaire to foreign site, domestic questionnaire should be properly adjusted in social and cultural background, lifestyle, etc.

Purpose: Oral mucositis (OM) is a serious consequence of chemotherapy that cancer patients must undergo. The objectives of this study were to find out reliability and validity of patients self-reported daily questionnaires on OM, and the impact OM makes on daily functions. Method: To test the reliability of oral mucositis daily questionnaire (OMDQ), internal consistency of the instrument (Cronbach's ${\alpha}$ and correlation between items) and test-retest reliability were analyzed. Criterion validity and discriminative validity were evaluated using WHO, oral assessment guide, and Nicolatou assessment tool. Forty-eight acute leukemic patients under chemotherapy were enrolled in this study. Result: The Cronbach's ${\alpha}$ coefficient indicated sufficient internal consistency. Correlations of Mouth and throat soreness (MTS) and MTSActivity Limitations (MTS-AL) were statistically significant. MTS and MTS-AL scores on consecutive days were highly correlated (days13,14=.84-.96; test-retest reliability). OMDQ scale had high criterion validity and discriminative validity. Patients with more severe WHO OM grades had higher MTS mean scores. Conclusion: Oral mucositis in acute leukemic patients under going chemotherapy can be easily quantified by patient self-administered OMDQ with reliability and validity.

The present study was conducted to develop a Multi-dimensional Body Image Scale for Malaysian female adolescents. Data were collected among 328 female adolescents from a secondary school in Kuantan district, state of Pahang, Malaysia by using a self-administered questionnaire and anthropometric measurements. The self-administered questionnaire comprised multiple measures of body image, Eating Attitude Test (EAT-26; Gamer & Garfinkel, 1979) and Rosenberg Self-esteem Inventory (Rosenberg, 1965). The 152 items from selected multiple measures of body image were examined through factor analysis and for internal consistency. Correlations between Multi-dimensional Body Image Scale and body mass index (BMI), risk of eating disorders and self-esteem were assessed for construct validity. A seven factor model of a 62-item Multi-dimensional Body Image Scale for Malaysian female adolescents with construct validity and good internal consistency was developed. The scale encompasses 1) preoccupation with thinness and dieting behavior, 2) appearance and body satisfaction, 3) body importance, 4) muscle increasing behavior, 5) extreme dieting behavior, 6) appearance importance, and 7) perception of size and shape dimensions. Besides, a multidimensional body image composite score was proposed to screen negative body image risk in female adolescents. The result found body image was correlated with BMI, risk of eating disorders and self-esteem in female adolescents. In short, the present study supports a multi-dimensional concept for body image and provides a new insight into its multi-dimensionality in Malaysian female adolescents with preliminary validity and reliability of the scale. The Multi-dimensional Body Image Scale can be used to identify female adolescents who are potentially at risk of developing body image disturbance through future intervention programs.

Various researches on the application of polymer dispersions to the cement mortar and concrete have been carried out in many countries like America, Japan and Germany and so on due to their high performance and good modification effect. PAE of polymer dispersion widely used in situ was employed that the high flowability may be induced in the cement mortar. In order to investigate the modification of cement mortar with high flowability by PAE and fracture mode of adhesive strength properties in tension of that, experimental parameters were set as PAE solid-cement ratio(P/C) and cement: fine aggregate(C:F) and the experiments such as unit weight, flow, consistency change, crack resistance and segregation that inform on the general properties have been done. Adhesion in tension is measured with a view to comprehending the properties and fracture mode in tensile load. Consistency change of cement mortar modified by PAE did grow better as the ratio of PAE solid-cement increased and was much superior to that of resin based flooring such as polyurethane and epoxy which recorded the loss of consistency in 90 min. after mixing. Adhesive strength in tension increased with continuity during curing period and showed the maximum in case of C:F=1:1 and P/C=20%.
