Purpose: In this study, we try to figure out the appropriate size of commercial districts in the original downtown area through empirical studies targeting the Jinju Central Commercial Area in Gyeongnam and Cheonan Station in Chungnam, which are trying to regenerate a specific space that has been lost through government projects. Research design, data and methodology: The current status and characteristics of the shopping district were examined through on-site surveys of the central business district of Jinju, Gyeongnam Province, and Cheonan Station, Chungnam Province, and the size of the empty stores was determined. In addition, the standard median income was used as the survey data along with the survey of the mobile population in the commercial area. Result: The analysis result shows that 883 stores should be maintained considering the overall expenditure and gross sales profit within Cheonan Station in South Chungcheong Province. Currently, considering spending and margins in the Commercial Area, Jinju Central Commercial Area is a place where 222 stores can be sold excessively, and a proper commercial supply plan is needed. Conclusions: In this study, we conducted a demand prediction study in the commercial sector of the most basic sector to regenerate the commercial sector through major regional commercial districts.

In this study, we aimed to propose enhancements to the dimensions and design of walking aids tailored for elderly women. Specifically, we focused on wheeled walking assistance devices and aligned each structural component with the appropriate human body dimensions to suggest appropriate product dimensions organized by size clusters, aiming to maximize the practicality of the results. We extracted essential factors required for product design, including human body size elements. The dimension extraction method was clustered to establish connections between key human body parameters-such as height, weight, and age groups-and product dimensions. We conducted a comparative analysis of walking aid product dimensions according to the design elements and sizes of models currently available in the market. The outcomes of this study offer objective, data-driven insights into areas where existing models on the market could benefit from improvement and we anticipate that the findings of this study will provide a solid, quantitative foundation for individuals when selecting the most suitable model for their needs.

This paper proposes a new face recognition technique in the dynamic link architecture which shows robustness against size variation and distortion. The face recognition technique in the dynamic link architecture so far was not appropriate for the recognition of various size of faces because of the fixed size of the graph and the fixed value of a of the Gabor filter not considering the size of the face. The proposed face recognition algorithm can represent the input facial image by a suitable size of labeled graph, and it can also adjust the dilation width and the height of the vibrating amplitude of the Gabor filter, thus face recognition in the dynamic link architecture is even applicable regardless of the size of the face.

The document "Understanding the Relationship Between Particle Size, Performance, and Pressure" explores the impact of particle size on chromatographic performance and system pressure. The study highlights how smaller particles can improve separation efficiency by providing higher resolution and faster analysis times. However, this comes at the cost of increased backpressure, which can challenge the system's hardware and require higher operating pressures. The document discusses the balance needed between particle size, column dimensions, and system pressure to optimize performance without exceeding the pressure limits of chromatographic systems. It outlines the advantages of using superficially porous particles (SPPs) over fully porous particles (FPPs) in achieving high efficiency with lower backpressure. The study also emphasizes the importance of selecting appropriate column dimensions and flow rates to manage system pressure while maintaining optimal performance. In conclusion, understanding the interplay between particle size, performance, and pressure is crucial for optimizing chromatographic separations, ensuring system longevity, and achieving high-quality analytical results.

Whenever planning a study design or preparing a research proposal it is highly recommended that investigators decide the optimum sample size that is required to yield an outcome of interest with a predetermined level of precision. This is because that, all else being equal, if a study with less than the optimum sample size would not detect the significance of differences in reality, and similarly, if a study with more than the optimum sample size will be costly. For these reasons, the majority of peer reviewed biomedical journals assess the adequacy of sample size requirements. The calculated sample size is used as a target number of samples to be collected to provide an estimate of the parameter with the desired and predetermined level of accuracy, and the sample size is a major determinant of the probability of detecting diseased animals from the population. There is no single method of calculating sample size for any given study design. In this context, the purpose of this article is to provide a collection of formulas and examples for some typical situations likely to be encountered in veterinary clinical practice and to highlight the importance of performing prospective sample size calculations when planning a research. Specifically, this paper is concerned with the basic principle of sample size calculation, and considerations for methodological applications were illustrated for a given data set. Also included in this paper is factors influencing sample size calculations using a statistically valid techniques. Appropriate methods to consider these factors are presented.

This study is designed to understand the problems of existing Korean male soldiers' winter uniform tops by researching its current state, and contribute to developing uniforms with improved size and motion appropriateness. Military bases were visited to research satisfaction of size and motion appropriateness of the current winter uniform tops. 193 soldiers were surveyed and interviewed, and the shape and fit of the standard sizes of the inner and outer layers of the current winter uniform were analyzed. Findings of this study are as follows. 1) Compared to the new combat uniforms that soldiers were wearing in their appropriate size (of the 44 sizes), there were many cases where the soldiers were not wearing winter uniform inner (of the 8 sizes) or outer (of the 18 sizes) layers in the correct size for their body. 2) A total of 37 combat uniform sizes appropriate for the body shapes were expected to be newly applied, and inside and outside layers of winter tops would be presented as sets of 14 different sizes in step with the new combat uniform sizes, instead of the existing 8 inside layer sizes and 18 outside layer sizes. 3) The inner and outer layer of the existing winter uniform tops had several problems with the shape and fit. First, the inner layer was shorter than the combat uniform. Its shoulder width was wide, but the sleeve length was short creating lack of coverage, and the angle connecting the sleeve and bodice was very small creating a high sleeve cap curve and narrow sleeve width that make motions difficult and cause discomfort. As for the outer layer, the hem moved up when soldiers bent over or adjusted the waist string so the top could not sufficiently cover, the shoulder width was wide and the sleeve length was short, requiring improvements.

The purpose of this study is to develop a basic sloper for pants that would be appropriate for young Korean school girls between the ages of 6 to 11 years old. Pants available in the apparel market for children do not properly correspond to the body size of the target consumer group. This research explores the characteristics of the body size of the group and also identifies problems of the conventional pants sloper that would be generally used for the production of children's apparel. Ultimately it presents a basic sloper for a possible use for manufacturing. The basic slopers for pants were collected from three different companies and were the examples used for this study. An experimental pants sloper was developed, reflecting the average body size of a nine year-old girl, which Is thought to be the master size for grading in children's wear Four different cotton prototype pants were made based on the three companies' slopers and the experimental one for evaluation of the fit and overall shape of the pants on subjects. The results revealed that the design, fit, and overall look of the experimental pants was superior to that of the opposing companies' product. After alteration of the experimental sloper, a basic pants sloper was finalized. The finalized pants sloper was determined at W/4+1cm for the front waist and W/4+2cm for the back, H/4+0.5cm for the front hip and H/4+1.5cm for the bark hip, and 73cm for its length with 15.5cm and 18cm for its front and back pants width at the bottom, respectively.
