The purpose of this study is to suggest the standard of bodytype which offers various data with regard to three-dimensional characteristics of body, and which offers the criterion for the sizes and shapes to interpret various bodytypes, to estimate filling, and to construct ready-made clothing. In this study, standard bodytype was defined as a typical type with beautiful proportion and shape which a large number of people have, too. In order to continue this study, there were two ways of analyzing bodytypes of subjects in the view of statistics and beauty. We primarily carried on statistical analysis in this report. Taken as a sample, the subjects were ninety-seven females who were between the ages of 18 and 24 years o1d. They were measured on November 1999. The data of seven hundred and few females, 18∼24 year-old, from the National Somatometry Survey of 1997 were used for analysis, too. Three kinds of classification methods were used for statistical analysis. The first method was based on the lateral view of the body, the second was based on the Factor and Cluster analysis of the photographic measurements of each of the anterior and lateral body, and the third was based on the Factor and Cluster analysis of the anthropometric measurements of the whole body. From the analysis on the distribution of R hrer Index the difference of width, the difference of depth, the proportion of height and head height, the High-frequency Proportion(H.P.)range were selected. The straight type from the lateral view, High-frequency type from each method, and subjects in H.P. range were compared with each other. As the result, it was confirmed that it is proper to base on the size and shape of subjects in H.P. range to analyze the standard bodytype.

This study aims to analyze the cases of storage space outside housing unit and propose the activation plan. The issue of storage in residential complex has continued to be reported. This is more salient due to the recent preference trend for small houses, the constant increase of living goods and the limitation of the available space inside housing unit. Although more apartment houses are trying to have individual storage in the exterior space to address these issues, there is still a paucity of the related studies and more studies are required. In this study, we conducted on-site investigation and user interview of each case to propose active usage of the storage space outside housing unit. Result of this study shows that the most crucial factor to improve is 'accessibility' in order to activate the storage space. Storage room should be located close to each household or the individual parking space. The second factor is the size and the structure of the storage room. The sufficient space for keeping and taking large objects out are required. The front of the storage room should have a clogged structure to insure privacy. The third is the provision of suitable support programs such as the system that occupants can check remotely what items are in their storage rooms, garage sale, laundry service, auto cleaning system and rental program. Those programs are required for efficient management and activation of space. Another requirement is to improve environmental factors which include maintenance of optimal temperature and humidity, automatic ventilation system, control of individual lights, and security enhancement. Based on the results of the survey, we provide basic data which can be used for practical space planning to activate exterior storage space of the housing unit. Further surveys are required to develop this study by obtaining more data for generalization.

The stream morphological characteristics of a basin have important influence upon the analysis of runoff. In this study, the laws of stream morphology-the law of average stream fall and the law of least rate of potential energy expenditure-which were derived based on the analogy of entropy in thermodynamics are introduced and their validity is analysised with the data taken from the topographic maps covering the whole Geum River system. The first law is the Law of Average Stream Fall which states that under the dynamic equilibrium condition the ratio of average fall between any two different order stream in the same river basin in unity. The second law is the law of least rate of energy expenditure which states that all natural streams are intended to choose their own course of flow such that the rate of potential energy loss per unit mass of water this course is a minimum. The parameters representing the morphological characteristics of 13 tributaries in the Geum River system such as stream bifurcation ratio and stream concavity were Computed from the Horton-Strahler's laws and are used to check the law of average stream fall. The result showed that the law of average stream fall agrees reasonably well with law of Horton-Strahler. Concavity of a river basin is shown to be the determinative factor to the formation of a stream system. Concavity of a river basin is shown to be the determinative factor to the formation of a stream system. Based on Horton's Law and the law of average stream fall, longitudinal stream profiles can be calculated.

There have been lots of studies on locational factors of companies, but, very few studies for Korean shipping companies. This study analyzes locational factors for Korean shipping companies using AHP(Analytic Hierarchy Process) method. For the study model, the first level is consisted by software, hardware and city policy factors. As more specific factors, the second level is formed by three factors of the first level. The third level consists of Seoul and Busan to evaluate competitive advantage for location of shipping companies. We carried out an analytical survey focused on the executives of shipping companies and related experts, and derived the priority order for locational factors of Korean shipping companies as follow. Firstly, software factors turned out the most important factor for location of Korean shipping companies. Next, Busan has a competitive advantage only in city policy factors. However, there are much of competitive disadvantages in both software and hardware factors for location of shipping companies compared against Seoul.

This study conducted to find influences of selection attributes on consumer satisfaction as perceived by low-cost restaurant visiter by considering personal value. Developed survey was distributed and 428 sample who visited the low-cost franchise restaurant were employed the statistical analyze. The internal value and the external value included individual value in order to estimate the influence of the choice factor of the low-cost franchise restaurant on the quality of the product, and the choice factors were consisted of 3 variables that are quality, accessibility and service. Regression analysis was conducted to verify the relationships among the variables. As a result, the internal value (${\beta}=.236$, p<.0.01), and external value (${\beta}=.352$, p<.001) have the significant positive relationships with respect to quality. Second, the external value (${\beta}=.305$, p<.001) has the positive relationship with regard to accessibility, but the internal value has no significant relationships with level of accessibility. Third, the internal value (${\beta}=.828$, p<.001) has the significant positive relationship with regard to service, but there was no significant influences between external value and service in this study. Fourth, the internal value (${\beta}=.472$, p<.001), the external value (${\beta}=.479$, p<.001) were critical antecedents of the quality. Last, while quality (${\beta}=.858$, p<.001) has significant positive relationship with satisfaction, but it didn't show any relationships with accessibility and service.

The aims of the study are first, in other to meet the demand for a new product design process, to review the prototype theory and to find out the conceptual structure of product aesthetics, which is another properly thought to be as important as the typical pattern in an effort to patch up the theory second to help designers overcome the limits of idea generation and create consumer oriented designs with a high success rate by setting up a new product design process that is established through the application of the aesthetically influential factor 'proportion'based on the preceeding studies that tested product aesthetics measuring devices. In other words, this study tries to find out product categories, making use of the prototype theory to introduce an ideal proportion for product design, recognizing the importance of proportion by conducting product pattern analysis: to create a differentiated method that can product consumer oriented designs, even if it only manipulate proportion and to establish a new design process that can systematically explain the methodology for various form generation that applies proportion. This study reviews the theoretical aspects of concepts pertaining to the above … and, based on them, empirically tests them by patting to use the programs, for proportion manipulation. This study was conducted in the following way: To begin with, this study takes out proportion out of some aesthetically influential factors that has a great impact on the way consumers prefer certain product designs and tries to see how proportion affects the consumer preference when consumers select a product. In addition, we could analyze the difference between the ideal proportion that consumers prefer and the traditional golden proportion produced through theoretical studies. The correlations between preferred proportion and ideal proportion, and preferred proportion and golden proportion could be shown. In order that we may create form variations through more detailed proportion manipulation on the basis of the ideal proportion verified as preferable, we again applied the proportion factor to the process utilizing PDS(proportion Distortion System). In the way the restraint of form generation could be pursued. All in all, this study makes an attempt to set up a design process to create new product forms through the application of Proportion.

In order to test scaling assumption, and to assess the validity, reliability, and acceptability of the Short form 36(SF-36) health survey questionnaire, we conducted a survey. Samples were 296 workers who had been employed in small sized companies. All scale passed for item internal consistency(100% sucess rate) and item discriminant validity(100% success .ate). Reliability coefficients were ranged from the lowest 0.51 to the highest of 0.85. For 87.5% of the total workers, inconsistent responses were not observed. Only 3.0% of the total workers failed two or more checks. Factor analysis was performed using principal axis factor method and quartimax rotation. In this survey, the SF-36 retained available psychometric properties even when used in a generally healthy worker group. But further study with some consideration to develope health status measurement is expected : first, the definition of health status should be rationalized. Second, the measurement of outcome is an important consideration in evaluations of quality of care. But ambiguities hinder understanding of this important topic. Third, internal consistency should be interpreted with caution as an indication reliability because it ignores potentially important sources of variation that can occur over time.

In order to improve the workflow of 3D video production, this paper analyzes the visual fatigue caused from distortions in 3D video production stage through a set of subjective visual assessment tests. To establish a set of objective indicators for subjective visual tests, various distortions in production stage are investigated to be categorized into 7 representative visual-fatigue-producing factors, and to conduct visual assessment tests for each selected category, 4 test video clips are produced by combining the extent of camera movement as well as the object(s) movement in the scene. Each produced test video is distorted to reflect each of the selected 7 visual-fatigue-producing factors, and we set 7 levels of distortion for each factor, resulting in 196 5-second-long video clips for testing. Based on these test materials and the recommendation of ITU-R BT.1438, subjective visual assessment tests are conducted by 101 applicants. The test results provide a relative importance and the tolerance limit of each visual-fatigue-producing factor, which corresponds to various distortions in 3D video production field.
