The quality characteristics of muffins with different types of rice flour, such as soft flour (CON), soft rice flour (SRF), floury rice flour (FRF), and rice flour (RF) were assessed by using Image J program, which includes their particle size analysis, moisture content, pH, color, specific volume, baking loss rate, texture. (D[4, 3]) is weighted mean diameter, which is directly obtained in particle size measurements showed large values in the order of rice flour, floury rice flour, soft rice flour, and soft flour. The moisture content was high in the CON and SRF groups with small particle sizes. There was no significant difference in pH, L and b value. The a value was significantly low only in the RF group with large particle size. The smaller the particle size, the higher the specific volume and baking loss rate. Image J showed that the number of pores decreased when fewer smaller particles were the powder, but the pores were larger. Among the rice flours, the SRF group, excluding the CON group, scored high in all the acceptability elements. The results from this study can be used as basic data that can contribute to research on various rice-processed foods.

This study was conducted to analyze the antioxidant and antidiabetic activities of acorns according to the types of Quercus serrata Thunb (QST) and Q. acutissima Carruther (QAC). The total polyphenol contents of the extracts from QST and QAC were 220.59 and 320.96 mg GAE/g, respectively. The content of total polyphenol of QAC was higher than that of QAC (p<0.001). DPPH (2,2 Diphenyl 1 picrylhydrazyl) radical scavenging activity, reducing power and superoxide dismutase (SOD)-like activity were increased in a concentration-dependent manner by both acorn extracts, and QAC showed high activity in all antioxidant experiments (p<0.05). The inhibitory activities of α-glucosidase and α-amylase were also increased in a concentration-dependent manner, and QAC showed higher inhibitory activity than QST (p<0.05). Our study indicates that QST and QAC are functional food materials with high antioxidant and antidiabetic activities. In addition, QAC has a higher physiological activity than QST.

The purpose of this study is to develop a new environmental policy paradigm for green economy and sustainable development and to develop major policy tasks in each field based on the analysis of internal and external environmental changes and current and future environmental issues. Changes in population structure such as aging population and low fertility, personalization and localization, urbanization and depletion of resources, international power movement and New Normal, new technologies such as Big Data in accordance with the 4th Industrial Revolution are demanding fundamental change of development paradigm such as green economy for development. Along with such changes, new changes in environmental administration and governance systems are required, including integrated response systems for cross cutting across ministries such as fine dust, biocide, climate change, and environmental disaster. In addition, it is necessary to effectively reorganize the environmental finance and tax system to solve the environmental finance pressure due to the rapid increase in public demand for health, safety and environmental services. As a major policy agenda in the field of environment, it is necessary to realize the environmental rights of the people, to coordinate and restructure the environmental governance, to establish sustainable smart-city environment management, to establish a system to cope with global fine dust, improvement of environment of 4 rivers and unification of water management, and response to integrated climate change - establishment of environmental disaster response system. The following are specific policy tasks for each sector to realize this policy agenda. Major policy tasks in the atmosphere sector have been proposed such as integrated management of fine dust, enhancement of effectiveness of fine dust management in transport sector, and improvement of management system in atmospheric environment information. Second, major policy tasks in the field of water environment are improvement of sustainability in water infrastructure, improvement of water cycle, development of water industry. Third, in the field of natural resources conservation, main streaming nature conservation and wise use of natural benefits have been proposed as major policy tasks. Fourth, in the field of resource recycling, realization of landfill zeroing through resource virtuous cycle, management of cyclic resource whole cycle and improvement of resource efficiency, proper management of waste due to complex disasters and nuclear dismantlement, and waste resource management for coping with future social change are major policy tasks . The main policy tasks for environmental governance will be to consider integration between relevant sectors. Regarding the rationalization of the distribution of the central-local environmental affairs, it can be achieved through the introduction of a differential decentralization system and strengthening cooperation between central and local governments. In order to reorganize and stabilize the financial system of the environment sector, two ways have been largely derived. First, the following two improvement measures were proposed in the traffic·energy and environmental tax sectors. The first is to impose the carbon tax, energy tax and environmental tax on all energy sources without extending the sunset. The second is to extend the deadline of the traffic, energy and environmental tax law and coordinate the price, and annual expenditure ratio in relative price of oil type. Next, in the charge of the Ministry of Environment, the measures to consolidate the transportation energy environment tax after the abolition of the charge, or to transfer the local area were suggested.

In this study, by replacing makgeolli in jeungpyeon manufacturing with won-ju (raw makgeolli) and standardizing the mixing ratio, it was intended to provide information that could suit consumers' tastes and utilize the added value of won-ju (R10, R20, R30, R40 means amounts of raw makgeolli). Raw makgeolli content did not significantly differ in moisture content. pH, L value, hardness and gumminess decreased with increasing addition of raw makgeolli, while the b value, adhesiveness, springiness, cohesiveness, and chewiness were increased. The specific volume was the highest following method R30, and the expansion rate was the lowest following method R40. The observation with Image J showed that as the amount of raw makgeolli increased, the pore size became larger, and the number of pores decreased. As for the sensory evaluation and results of jeungpyeon, the R30 group showed the highest score in all items(flavor, appearance, texture, taste, overall acceptability). Therefore, this study suggests that Jueng-pyun produced with the R30 mixing ratio has excellent quality and sensory characteristics. Furthermore, the results can be used as foundation data for the standardization of won-ju jeungpyeon production.

In this study, we aimed to investigate the quality characteristics, antioxidant activity, and sensory traits of meringue Jeung-pyun with different amounts of cacao bean husk powder. Based on our analyses, high cacao bean husk content resulted in an increase in certain Jeung-pyun qualities, such as the L values, b values, hardness, gumminess, and number of pores, whereas the moisture content, pH, pore size, adhesiveness, cohesiveness, and chewiness significantly decreased. Electronic tongue analysis showed that the intensity of sourness, saltiness, and umami increased with the amount of cacao bean husk added. For the sensory characteristics, C6 demonstrated the highest ranking for all test items. Furthermore, it was found that the addition of cacao bean husks increased the antioxidant activity of the Jeung-pyun (p < 0.001). Therefore, these results suggest that Jeung-pyun produced with a mixing ratio of C6 has excellent qualities, antioxidant activities, and sensory characteristics.

This study investigated quality characteristics and antioxidant activity of beetroots after blanching. Beetroots wereblanched in distilled water, 2% NaCl water, and 2% citric acid water at 100°C for 3 minutes (the blanched group). Themoisture content was highest in the control (CON) at 91.30% (p<0.05), and cooking loss was lowest in the water-blanchedbeetroot (BW) at 5.39% (p<0.01). Chromaticity decreased after blanching compared to CON (p<0.001). Total polyphenolcontents (TPC) and total flavonoid contents (TFC) decreased after blanching, and as a result of comparing the True retention(TR) of the blanching treatment group, BW had the highest with TPC TR 91.22% and TFC TR 70.51%. DPPH and ABTS+radical scavenging activities were highest in the CON, and in the blanching group BW was highest scavenging activity. Thetotal number of microorganisms in the CON group was 2.97 log CFU/g, whereas no microorganisms were detected in theblanched groups. Therefore, this study, blanching in water without additives is the most appropriate method for preservingphysiologically active substances and nutrients in beetroots and inhibiting microbial growth.

Purpose: Revisit to the pediatric emergency department(ED) in the short-term period may be due to inadequateevaluation during the previous visit, which may indicate aproblem with quality in emergency care. The aims of thisstudy are to analyze the characteristics of patients whorevisited the pediatric ED within 48 hours after dischargeand to evaluate the relation between overcrowding andrevisit rates. Methods: Retrospectively, we reviewed the charts ofpatients who returned within 48 hours after visiting a PEDduring a one-year period between June 1st, 2011 andDecember 31st, 2011. We determined the rate of return visitsand review the characteristics of patients, emergency severityindex (ESI) level at visits, cause of revisit, diagnosis, andcrowding degree of the pediatric ED at the patient’s first visit. Results: A total of 16,688 patients visited the pediatric EDand 13,716 patients were discharged from the PED duringthe period. Of these discharged patients, 534 patients revisitedinevitably within 48 hours. The most common cause ofrevisit was relapse or worsened symptoms (70.0%). Therewas no significant difference in sex, severity of patient, andcrowding degree of the pediatric ED at the first visit, however,patients who revisited were younger than those who didnot (p=0.005). The ESI level at the return visit was significantlyhigher irrespective of admission after revisit(p<0.001). In diagnosis grouping, patients with gastrointestinaldiseases, respiratory diseases, and neoplastic diseasesshowed a higher rate of revisit. Conclusion: Approximately 4% of our pediatric ED visitswere for children returning within 48 hours. Patients whorevisited were younger and patients with gastrointestinal diseases,neoplastic diseases, and respiratory diseases weremore likely to revisit. Careful explanation of the possibility ofworsened symptoms is necessary for these patients.
