To improve urban safety there is an increasing social need for environmental design against crime, which is defined as the creation of inconvenient environments or situations for criminal offenders. By using a cluster analysis, we aimed to clarify crime occurrence patterns from the perspective of land-use. Osaka Prefecture was chosen as the study area because it has the highest crime rate in Japan. The results revealed that there are six patterns of crime occurrence, and that cities of medium-level of mixed land-use have the lowest crime rates.

This study has been given careful consideration to an induction of the mixed-use districts for the efficiency of Land Use, the rational plot planning and the mixture/complex among the functions in order to complement the zoning plan with the primary purpose to purify the usage of landscape. Furthermore, it is aimed to indicate the implementations through the medium of the in-depth analysis about the cardinal factors such as the standards on the regional location, building size and building uses in the case of designating the Mixed-use districts.Abstract This study has been examined by the aspect of scope for securing the adequacy of Site Division Restriction, Floor Area Ratio, Building Coverage Ratio and Outdoor Area Ratio in the "Mixed-Use Districts" and especially, by the medium of the in-depth analysis about the actual condition of building and outdoor space scales. It has been deduced the scale standards by using the simulation and correlation analysis among the factors of those buildings and outdoor spaces. Moreover, it has been applied the analysis method of using the building scale, especially, the latter has analyzed the total 1,656 different types classified by 3 patterns of Plottage and Building Coverage Ratio, 9 patterns of the factor change on Outdoor Area Ratio and 8 different patterns of road width.

The research is carried out to analyze the cost-effectiveness of blasting patterns with regard to the diameters and design of blasting holes. Blasting patterns for single diameter array, and mixed diameter array were comparatively analyzed with regard to drilling and charging time, and materials required. The number of blasting holes required for single array pattern and mixed array pattern were 138 and 93 holes, respectively. From the drilling time analysis, reduction in time and its efficiency of mixed pattern were 139 minutes and 25%, respectively, in comparison with single pattern. Charging time reduction and its efficiency of mixed blasting pattern were evaluated as 22.5 minutes per worker and 33%, respectively, compare to single blasting pattern. The explosive quantities of G1 and G2 required for single array patterns were 270 and 30, while those were 222 and 20 for mixed array patterns for tunnelling 4m. And single pattern required 45 more detonators than the mixed pattern. The evaluation of material required can also be positive parameter for cost reduction of tunnel construction.

Mixed standard-FLIP fuel loading patterns in the TRIGA Mark-III reactor were analyzed. It was judged that the mixed loading pattern with the standard fuel in the B-ring and the FLIP fuel in other rings was mostly desirable in view of fuel temperature, cooling condition with the natural convection, or effective thermal flux utilization in the central thimble. In addition, tile maximum useful flux in tile reactor beamports versus the loading patterns was evaluated.

The purpose of this study was to grasp the utilization of traditional Korean Patterns used for fashion cultural products. To achieve this purpose, this study examined the range of fashion cultural products through literature review, previous researches, and market surveys and analyzed the situation of fashion cultural products and the kinds, expression methods, expression techniques, and repeat styles of utilized patterns. The analysis results are as follows. First, in the use of traditional pattern, the most frequently-used fashion cultural products were small and inexpensive accessories, followed by fashion apparel, miscellaneous goods, and living cultural goods. Second, the most frequently-used traditional patterns were plant patterns, especially flower patterns. The next frequently-used ones were mixed patterns, especially in the mixture of flower and letter patterns, and $cloisonn\'{e}$ and flower patterns. The next frequently-used traditional patterns were animal patterns(especially butterfly patterns), followed by geometric patterns, lucky omen patterns, and letter patterns. In the expression methods of used patterns, most products except handicrafts preferred simplified patterns to real patterns. Finally, in the expression techniques of traditional patterns, the most frequently used technique was traditional embroidery, followed by the use of weaving fabrics such as fine gauze and brocade which are used for Hanbok. Also, transfer dyeing which is one of printing techniques, DTP(digital textiles printing), a mixed technique which adds embroidery to weaving fabrics, hand-painting, and a gilt technique were used. The results of this study suggest that most fashion cultural products except few designers' works attached weight to some specified patterns and expression techniques regardless of the characteristics of products since there is little understanding of a variety of patterns and are few researches and development on expression techniques.

The purpose of this study was to identify dietary patterns among children and adolescents in Korea and to examine their associations with obesity and some blood profiles. One day food consumption data measured by 24-hour recalls on 2704 subjects aged 1 to 19 were used from 2001 Korea National Health and Nutrition Survey. The data of blood profiles available in the ages of 10 or older was also used. After categorizing each food consumed into 29 food or food groups, five dietary patterns were derived through a factor analysis and subjects were classified into three major dietary patterns via a cluster analysis using the factor scores. Three dietary patterns were identified as 'traditional diet' (25.6%), 'westernized-fast food' (6.2%), and 'mixed diet' (68.2%). The 'traditional diet' pattern had a higher percentage in boys. Both the 'traditional diet' and the 'westernized-fast food' had higher proportions of adolescents (12-19 y) than younger children, while the 'mixed diet' had a higher percentage of preschool children (1-5 y). Obesity rate analyzed within each age group showed no differences among 3 dietary pattern clusters. Blood pressure and all plasma profiles were not different among dietary patterns when adjusted with age and gender. Conclusively, children and adolescents in Korea had three distinct dietary patterns, which were associated with gender and age. These patterns could be useful to plan nutrition interventions for teenager health promotion.

In this paper, a mixed algorithm is proposed to overcome the limitations of the conventional algorithms, which cannot be applied in various driving patterns of drivers. The proposed algorithm based on the coulomb counting method is mixed with reset algorithms that consist of the enhanced OCV reset method and the DCIR iterative calculation method. It has many advantages, such as a simple model structure, low computational overload in various profiles, and a low accumulated SOC error through the frequent SOC reset. In addition, the enhanced parameter based on a mathematical analysis of the second-order RC ladder model is calculated and is then applied to all of the methods. The proposed algorithm is verified by experimental results based on a 27-Ah LiPB. It is observed that the SOC RMSE of the proposed algorithm decreases by about 9.16% compared to the coulomb counting method.

We frequently encounter outcomes of count that have extra variation. This paper considers several alternative models for overdispersed count responses such as a quasi-Poisson model, zero-inflated Poisson model and a negative binomial model with a special focus on a generalized linear mixed model. We also explain various goodness-of-fit criteria by discussing their appropriateness of applicability and cautions on misuses according to the patterns of response categories. The overdispersion models for counts data have been explained through two examples with different response patterns.

This purpose of this study is to figure out the inter-relationship between the residence stories in high-rise mixed-use apartments and their residents' disease patterns throughout the dweller's medical reports in high-rise mixed-use apartments. Research basic data are obtained from medical fee request of National Health Insurance Corportion. Data are limited a housing complex to 'A' high-rise mixed-use apartment and a medical treatment time to 3 years(2004-2006). Analysis data of total 346,286 medical records, 43,159 disease records, and 8,999 persons are collected. By analyzing those data, findings are as follows: 1) Women is more medical treatments than men, 40-50 age group is more treated, and the residents of 6-25 stories are more received medical treatments. Diseases of the respiratory system and diseases of the eye and adnexa are relatively treated higher than other diseases. 2) The diseases of the respiratory system, the eye and adnexa, the skin and subcutaneous tissue, the ear and mastoid process), and the asthma have not relation to the high-storied residence through the data of disease records and personal records. But the analysis on the data of children, 7 ages and less, is showed a significant relation. And to conclude, there is no relationship between the residence of high-stories in that apartment and dwellers' disease patterns, but there is a little probable to the relationship in the pre-school child.
