This study aims to explore the multiple characteristics of the edges and analyze the cases of Seoul Forest and Busan Citizen Park focusing on urban connectivity, and to present implications for the recent increase in development of urban relocated sites. In terms of connectivity, the two parks were connected to the surrounding urban fabric using crosswalks and pedestrian paths. In terms of Placeness, Seoul Forest formed its edges as a space to stay compared to Busan Citizen Park. In terms of porosity, both parks used planting and pedestrian skywalk, but some edges require conversion to mutually penetrating edges. The development of urban relocated sites is important in that it has an opportunity to establish new connections with surrounding urban fabric and reorganize urban spaces. Therefore, these results can be used as a initial data for design strategies to restore urban connectivity.

Counting Bloom Filter(CBF), Quaternary Bloom Filter(QBF) and Invertible Bloom filter(IBF) are structures that can do delete operation by modifying the standard Bloom filter. CBF can have overflow, which can lead to false negatives. QBF, which is composed of a 2-bit counter, indicates the corresponding cell as an X when three or more elements are mapped. There is no false negative in QBF because deletion does not occur for cells with X. The 6-bit invertible Bloom filter(IBF) used in this paper consists of two fields : 4-bit signature and 2-bit counters. In this paper, we compare the performance of three types of bloom filter: 4-bit CBF, QBF and 6-bit IBF. Simulation results show that QBF has the lowest false positive rate.

The Outdoor play environment is a very important space in contributing to childrens health and development. There are considerable research activities regarding the quantitative distribution and equity of the outdoor play environment. However, in Korea, there are not enough studies examining the equity of childrens outdoor play environments. In this study, playgrounds and childrens parks data were created and collected using the ArcGIS Pro program to confirm the quantitative differences in outdoor play environments according to the distribution of children in housing poverty in Seoul. By analyzing the spatial distribution pattern of children in housing poverty in Seoul, a total of 26 administrative boundaries were selected as the site. The number and area of play environments for each group was calculated and compared. As a result of the analysis, the low-group with a significant number of children in housing poverty suffered a double deficiency compared to the mid- or high-group in terms of the number, area, density of playgrounds and area of childrens parks. To overcome such inequity, it is necessary to supply outdoor play environments more equitably in terms of multidimensional aspects such as the number, area, and density. In addition, it is necessary to consider the area of residence, the number of children, and the main housing type.

This study investigated the potential for using vegetable powders as a natural replacement for sodium nitrite and their effects on the physicochemical characteristics of alternatively cured pork products. We analyzed pork products subjected to four treatments: control (0.015% sodium nitrite), Chinese cabbabe powder (CCP) treatment (0.4% Chinese cabbage powder), radish powder (RP) treatment (0.4% radish powder), and spinach powder (SP) treatment (0.4% spinach powder). Among the vegetable powders prepared in this study, SP had the highest (p<0.05) nitrate content, while CCP had the lowest (p<0.05). The cooking yields from these treatments were not significantly different from each other. However, the products with vegetable powders had higher (p<0.05) pH and thiobarbituric acid reactive substances values than the control. Pork products with vegetable powders also showed lower CIE L* values and higher CIE b* values than the nitrite-added control. RP treatment had similar (p>0.05) CIE a* values to the control, while SP treatment had the lowest (p<0.05) CIE a* values. The residual nitrite content was lower (p<0.05) in the vegetable powder added pork products than in the control, although nitrosyl hemochrome and total pigment contents in the CCP and RP treatments were similar (p>0.05) to those in the control. The control, CCP, and RP treatments showed curing efficiencies greater than 80%, indicating that CCP and RP would be promising potential replacements for sodium nitrite. The results of this study suggest that RP may be a suitable natural replacement for sodium nitrite to produce alternatively cured meat products, compared to other leafy vegetable powders.
