For the large scale retailers such as chain discount stores and specialty stores, having measurement tool to maintain service quality can be very crucial to sustain high and same level of service qualities around multiple stores. This study aims to develop service quality scales of large-scale stores using Korean discount store cases. We have studied the previous service quality measures including RSQS(Retail Service Quality Scale) and have modified and developed our own scale model called KD-SQS(Korea Discount Service Quality Scale). The following six components have been revealed as the basic dimensions of service quality of Korean discount stores: basic benefits, promotion, personal interactions, physical aspects, policy and additional convenience. Our scales have been verified through various validity and reliability tests.

Background: The categorical scales and visual analogue scales (VAS) are methods used for evaluating variations of postoperative pain intensity. Several studies have introduced the idea that there is a clear correlation between visual scales and categorical scales. However, when VAS is the only pain measure in the study, we do not know what point on the VAS represents a category on the categorical scale and their degree of correlation with satisfaction for postoperative pain. Methods: 252 patients who had undergone elective surgery were studied. A 5-point categorical scale (none, mild, moderate, severe, worst possible pain), a 0-100 mm VAS (no pain to worst possible pain) and patient satisfaction score were checked 24 hours after surgery using a pain questionnaire and VAS tool. Results: The mean VAS score of the 14 patients reporting 'no-pain' was $1.9{\pm}0.9$, $23.9{\pm}1.0$ for the 132 patients reporting 'mild-pain', $47.2{\pm}1.1$ for the 82 patients reporting 'moderate-pain' and $67.5{\pm}2.8$ for the 24 patients reporting 'severe-pain'. Of the patients reporting moderate pain, 85% scored over 45.6 mm on the corresponding VAS, with a mean score 47.2 mm. The mean satisfaction scores were $90.6{\pm}2.7$ for the 'no pain', patients, $75.1{\pm}1.3$ for ‘mild pain', $58.3{\pm}1.5$ for 'moderate pain', and $55.1{\pm}4.0$ for 'severe pain' patients. The categorical scale was significantly correlated with VAS (P < 0.01). The satisfaction score was significantly inversely correlated with VAS (P < 0.01). Conclusions: Our results indicate that if a patient records a VAS score in excess of 45.6 mm they would probably have recorded at least moderate pain on a 5-point categorical scale. The categorical scale can be used properly for postoperative pain measurement with VAS. More research is required for the development of suitable pain descriptor for a categorical scale and pain questionnaire in Korean.

The comprehensive understanding of the fiber reinforced polymer behavior requires the use of advanced non-destructive testing methods due to its heterogeneous microstructure and anisotropic mechanical proprieties. In addition, the material response under load is strongly associated with manufacturing defects (e.g., voids, inclusions, fiber misalignment, debonds, improper cure and delamination). Such imperfections and microstructures induce various damage mechanisms arising at different scales before macrocracks are formed. The origin of damage phenomena can only be fully understood with the access to underlying microstructural features. This makes X-ray Computed Tomography an appropriate imaging tool to capture changes in the bulk of fibrous materials. Moreover, Digital Volume Correlation (DVC) can be used to measure kinematic fields induced by various loading histories. The correlation technique relies on image contrast induced by microstructures. Fibrous composites can be reinforced by different fiber architectures that may lead to poor natural contrast. Hence, a priori analyses need to be performed to assess the corresponding DVC measurement uncertainties. This study aimed to evaluate measurement resolutions of global and regularized DVC for glass fiber reinforced polymers with different fiber architectures. The measurement uncertainties were evaluated with respect to element size and regularization lengths. Even though FE-based DVC could not reach the recommended displacement uncertainty with low spatial resolution, regularized DVC enabled for the use of fine meshes when applying appropriate regularization.

The purpose of this study is to discover unique personality traits which the children of 5 social status types using 10 clinical scales of Korea Children's personality test (KCPI-S) in order to define the characteristics of 5 social status types developed as the Korean type. For this purpose, two hypotheses were set and tested. The subjects of this study were 502 children who were 4, 5th and 6th grade elementary school boys and girls in A city. 5 social status types and gender of children were set as the independent variables each, and 10 clinical scales of Korea Children's personality test as the dependent variables. The research hypotheses were analyzed in turn by the multivariate analysis (MANOVA) and t-test. The results are as follows: First, the results of analyzing differences in 10 clinical scales in accordance with 5 social status types how the significant differences in all 9 clinical scales except for language development scale, and ${\eta}^2$ representing the explanatory power of the independent variables to dependent variables was found to be in the range of the lowest at 2% up to 10% for each scale. Second, the results of analysis of the gender difference show that in the case of the children with controversial and neglected children, the significant difference was appeared between boys and girls in 8-9 scales among the 10 clinical scales, but in the case of rest 3 social status types (average, popular, rejected children) the difference was appeared between boys and girls only in 2-3 scales. Depending on these results it seems that each of 5 social status types of the children has its own unique personality structure. It is necessary to attend to the fact that in the case of the children with controversial and neglected children, the average value of boys are significantly higher than that of the girls. There is a big possibility that the boys have more psychological problems that the girls. It is judged that in case of these two types the personal traits applying gender should be interpreted. Therefore, the follow-up study should conduct the exploratory research on the structure of the relationship between children's language development and sociality measure. Further, it is necessary to conduct the psychological comparison between genders in the children with controversial and neglected children, and to study the structure of their relationship with rest social status types by genders.

A study on the Manufactiring of High-Precision Linear Scale by the Use of He-Ne Laser Interference Of late, along with the advancement of procision machining technology, the reauirement of super-precision measurement increases as time goes on, and the precision and accuracy of standard scale which is a basis of procision measurement has been cognized as a oriterion of industrial development in a nation. Up to now, mechanical and chemical methods have been widely employed to carve scale lines on linear scale, and it is impossible for the linear scale manufactured by means of those methods to guarantee the measurement with sub-micron level owing to errors attended with various problems. And the measuring length also bears errors subjected to the influence of surroundings condition, and shows inefficient circumstances in measurement on the ground of the complexity of measuring procedure as well as massive measuring apparatus. Hence in this paper, we described on technology by which we can carve scale lines thru optical method under the condition of laboratory by using rhcoherence of He-Ne two-mode stabilized laser and in turn, put it to practical use as linear scale for the measurment of lengrh. In this researchin the case of setting scale interval to 20 .mu. m, we employed super-precision scale-carving device associated by Ar larser and acoustic optical modulator in lieu of flsahing lamp scale-carving device, and we consequently obtained superior linear scales carved with precision and accuracy of .+-. 0.3 .mu. m.
