In this study, the quality characteristics and antioxidant activities of wet noodles added with seunggumcho (Angelica gigas N Leaf) powder at concentrations of 1, 2, 3, and 4%, respectively, were investigated. The moisture contents and pH of the samples showed a tendency to decrease with increasing amounts of seunggumcho powder. Texture measurement indicated that 'hardness,' 'springiness,' and 'chewiness' of the cooked noodle were the highest in the control group, and these parameters showed a tendency to decrease with increasing amounts of seunggumcho powder. The total polyphenol contents in wet noodles added with seunggumcho powder increased with increasing amounts of seunggumcho powder. 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity was the lowest in the control group (10.85%) and highest in the 4% addition group (44.84%). ${\alpha}-Glucosidase$ inhibitory activity showed the lowest value in control group (1.17%), and increased with increasing amounts of seunggumcho powder. The sensory preference score was the highest for color, flavor, taste, and chewiness in the 2% addition sample. The findings of this study suggest the feasibility of seunggumcho added wet noodles as a health food with physiological benefits and provide evidence for introducing various health foods by adding seunggumcho.

As the main purpose of R&D changes from the center of knowledge creation to the center of economic value creation through technology transfer and commercialization, public technologies can also secure economic feasibility as well as make a social contribution. Korea has been focusing on fostering core human resources who can lead the commercialization of basic and original research results by launching the 'Support project for exploring startups linked with public technology-based markets' since 2015 in order to promote public technology startup. This study is based on the results of a survey for the purpose of analyzing the performance of this project. In addition, this study derived four factors related to the I-corps project performance from the results of this survey and verified the relationship between these factors through structural equation model analysis. In summary, it was confirmed that 'Application Level' and 'Business Model,' which are positively affected directly from 'Entrepreneurship Learning,' have positive effects on 'Financial Resources'. Furthermore, the indirect effect of 'Entrepreneurship Learning' on 'Financial Resources' was verified. In particular, the high level of impact of 'Entrepreneurship Learning' on 'Application Level,' and the impact of 'Application Level' on 'Business Model' and 'Financial Resources' were also positive.

This study examines the mediating effect of self-directed learning between the self-leadership and academic self-efficacy of beauty major Chinese(CN) students and examines the variables affecting the academic-self-efficacy of CN students. The study aims to obtain basic data to help improve college life in foreign countries. A survey was conducted upon 440 beauty major CN students in universities across Seoul. The results of the study showed differences in self-directed learning according to the number of semesters they have been in Korea and in academic self-efficacy according to their TOPIK levels. Self-directed learning was found to have a partial mediating effect between self-leadership and academic self-efficacy of CN students. These results showed that self-leadership and self-directed learning are major predictors of the academic self-efficacy, which is further reinforced when self-leadership and self-directed learning are promoted together. These results imply that there should be preceding efforts to promote both self-leadership and self-directed learning to increase the self-efficacy of CN students majoring in beauty.

This study was conducted to examine the experiences of nursing students during a clinical practicum at a university hospital in the Seoul metropolitan area. The participants of the study were 12 senior nursing students from J city, and the data was collected from September 29 to October 12, 2017, using interview questionnaires. The collected data was analyzed using Colaizzi's phenomenological analysis method. As a result of this study, there were three categories and nine theme clusters. In the category of 'high-quality practical education', 'the participants had high expectations prior to the practicum' and 'satisfaction with the practical instruction of education' as well as identified 'the opportunity to consider for future career'. In the category of 'experiences with independent social life', the participants described about their 'freedom away from everyday life', 'challenges of problem-solving alone', and identifying 'the importance of human relationships' in unfamiliar surroundings. In the category of 'lack of support system in practicum', the participants reported 'difficulties in preparing for practicum due to lack of information', 'lack of financial support' and 'the fear of living in an unsafe environment'. The results of the study will be used to as a basic data to find a high-quality clinical practice education environment by identifying what clinical practice students experience at university hospitals in the metropolitan area.

The present study investigated the quality characteristics of Perilla frutescens Britt. seed compounds according to the cultivar and sowing dates. In the present experiment, five Perilla cultivars, namely 'Dayu', 'Deulsaem', 'Deulhyang', 'Baekjin', 'Sodam', were planted on three different dates, including May 30, June 20, and July 10. The contents of key compounds and phenols varied depending on the cultivar and sowing date. With the delayed sowing time, the days to flowering and maturity of the culitvar decreased, while the seed weight and hardness increased. Crude protein content increased but crude lipid content decreased with the delay in the sowing time. However, there was no interaction of different sowing dates with the fatty acid content, which remained stable compared with the other values. Overall, the total polyphenol content was higher in Perilla seeds sown on May 30.

On September 23, 2020, at 1:39 a.m., a bright fireball above Seocheon was observed across the country. Two fireball explosions were identified in the images of the All-Sky Camera (ASC), and the shock waves were recorded at seismic and infrasound stations in the southwestern Korean Peninsula. The location of the explosion was estimated by a Bayesian-based location method using the arrival times of the fireball-associated seismic and infrasound signals at 17 stations. Realistic azimuth- and rang-dependent propagation speeds of sound waves were incorporated into the location method to increase the reliability of the results. The location of the sound source was found to be 36.050°N, 126.855°E at an altitude of 35 km, which was close to the location of the second fireball explosion. The two explosions were identified as sequential infrasound arrivals at local infrasound stations. Simulations of waveforms for long ranges explain the detection results at distant infrasound stations, up to ~266 km from the sound source. The dominant period of the signals recorded at five infrasound stations is about 0.4 s. A period-energy relation suggests the explosion energy was equivalent to ~0.3 ton of TNT.

The purpose of this study was to investigate the job satisfaction and quality of life of nurses in a integrated nursing care service ward (INCSW) and a general ward (GW). A total of 88 nurses working in INCSW and GW were invited and followed up for 6 months over 3 times. There was no significant difference in job satisfaction between INCSW and GW for 6 months, while there was a difference in quality of life: overall quality of life (1st p=.033, 2nd p=.030), and overall general health (1st p=.049). Comparison of two groups by period in job satisfaction, there were statistically significant differences of the item 'recognition from the organization and professional achievement' (2nd versus 3rd, p=.037) and 'interpersonal interaction with respect and recognition' (1st versus 3rd, p=.005; 2nd versus 3rd, p=.006) in the INCSW. Comparison of two groups by period in quality of life, there was a statistically significant difference of the item 'overall quality of life' (1st versus 3rd, p=.025; 2nd versus 3rd, p=.010) in the INCSW. Development of various nursing strategies (such as manpower arrangement that reflects the nursing skill levels, patient needs, job training and organizational culture before placement) can be helpful for improving nurses job satisfaction and quality of life in INCSW and GW.

The purpose of this study was to examine the relationship between metabolic syndrome and sugar intake. This study was conducted on adults aged over 19 who participated in the 2013-2016 Korea National Health and Nutrition Examination Survey. Subjects were classified according to the ratio of sugar intake to total energy. We used 24-hour recall survey data to investigate the daily sugar intake. The energy intake ratio from the sugar <20% group had higher % KDRI's of calcium, iron, potassium, vitamin A, riboflavin, and vitamin C than the energy intake ratio from the sugar ≥20% group. The risk of blood pressure level was higher in the ≥20% group than in the <20% group. The highest tertile of sugar intake showed an increased risk of elevated blood pressure level. This study found that increased sugar intake was associated with the risk of metabolic syndrome. It is expected that these results can be used as useful information to prepare basic data for establishing and managing sugar-reducing nutrition policies for the prevention of chronic diseases.

Rare earth elements (REEs) have been used as one of power tracers for understanding geological and environmental changes due to their similar physico-chemical properties. In this study, we investigated the characteristics of rare earth elements in atmospheric particulates(PM_2.5) collected in Beijing and Gwangju during January 2018. The total concentrations of REEs in the Beijing samples were about 16X higher than those in Gwangju samples, and both samples are enriched in light REE than heavy REE, up to 8-10 times. The Post Archean Australian Shale (PAAS)-normalized pattern showed that both samples are enriched in Eu, Tb, and Er, and displayed positive Eu but negative Ce anomalies. The elemental correlations indicate that both samples originated from China desert and Loess plateau as well as cities surrounding Beijing. This study suggests that REEs in PM_2.5 can be used as a powerful proxy of revealing the difference between China and Korea, and provide basic information on the source and transport of PM_2.5.
