This study investigated water quality characteristics and influencing factors of park drinking fountains having directly piped water systems by analyzing stagnation water (first draw) and water after a 10-minute flush (flushed water). First draws exhibited significant variations in residual chlorine, heavy metals, bacteria, and turbidity, which were largely influenced by usage frequency and external environmental contamination. However, water quality stabilized after flushing. A seasonal analysis indicated that the greatest difference in residual chlorine between first draws and flushed water occurred in spring, followed by that in winter when drinking fountains were discontinued, accompanied by increased zinc concentrations in stagnation water. A comparative analysis of water quality variability by faucet type revealed that push-button faucets exhibited greater variabilities in copper, zinc, and nickel levels than screw-down faucets, likely due to corrosive by-products generated from water hammer effects. Additionally, an analysis based on exterior material indicated that metal fountains experienced higher temperature increases and elevated zinc concentrations in first draws than stone fountains. Regarding installation environments, drinking fountains exposed to direct sunlight or partial shade had higher concentrations of copper, zinc, and nickel in first draws than those installed in constant shade. Overall, these findings suggest that frequent use or flushing can help maintain stable water quality with the exception of push-button faucets.

For this survey, PCR (polymerase chain reaction) testing was conducted using 14 species-specific primers to monitor the labeling of allergy-causing substances in various foods. Sixty samples from stationary stores near elementary schools and imported confectionery shops were tested, including snacks, candies, and chocolate. Allergens of milk, wheat, eggs, tomatoes, almonds and peanuts were detected in 30 cases (50.0%). In addition, many products were detected as either containing unlabeled substances or not showing allergen-related information and labeling in Korean. In order to ensure that consumers are able to purchase products safely and securely, a system for thorough guidance and monitoring of allergen-related labeling by domestic manufacturing and processing companies and import-related companies is required.

Public outdoor spatial environment and its convenient facilities are playing an important role in providing space for various student activities in university campus. Previous studies have shown that many socio-demographic-economic students' background and motivation have impacted the level of academic achievement. Moreover, research also contended that school facilities at some points also influenced students' academic performance. Thus, the aim of this research was to investigate the relationship between the level of academic achievement and satisfaction of various spatial environment through survey. For that purpose, one university campus was selected and evaluation indexes were categorized into five major components of physical and experimental environment, later supported by factor analysis. Correlation analysis found that extracted factors were significantly interrelated to academic achievement. Further, regression analysis also explored sense of belonging as major predictor of academic achievement. Finally the study suggested that campus plan be approached carefully, because such experimental environment as diverse club activities at outdoor environment is a key element to academic achievement even though rated low scores in satisfaction.

The activation of consumption of environment-friendly agricultural processed foods means not only the growth of environment-friendly agriculture, but also the development of related industries. Therefore, it is necessary to identify and apply the needs and purchasing attributes of environment-friendly agricultural processed food consumers. For this, survey was conducted to adult men and women in their 20s and 60s and a total of 200 copies were used for empirical analysis. In this study, the average difference between importance-satisfaction for purchase attributes of environment-friendly agricultural processed food was verified, and the IPA Matrix was prepared based on this. As a result, in terms of purchasing importance and satisfaction, it was found that those with no experience in purchasing environment-friendly agricultural processed foods regarded product, price, place, promotion as more important than those with experience in purchasing. In case of IPA, product and price factors were all important and satisfactory regardless of purchasing experience. On the other hand, it was found that the key factors for promotion were neither important nor satisfied with consumers regardless of their purchasing experience. Therefore, it is mainly necessary to focus on marketing and mass media promotion. At the same time, various domestic and foreign best practices should be benchmarked and a 4P marketing strategy should be established and promoted.

An educator may utilize various pedagogies such as hands-on practice, practicum, and project-based learning to enhance a student's competency. Among various pedagogies, project-based learning is one of the well-known pedagogies that may provide similar on-the-job experience. In general, an educator may divide the students into small groups and assign tasks to check students' cooperation skills and achievements during project-based learning. However, an educator may experience difficulties operating project-based learning due to the COVID-19 pandemic. Most of the team activities are done in non-face-to-face meetings, and as a consequence, the educator may not find an underachieving team easily and cannot intervene appropriately. This study introduces a rigorous analysis method to evaluate team activities to analyze individual students' participation and contributions. First, this study develops evaluation rubrics by conducting questionnaires to professors and students to find an appropriate weight value for the evaluation scale. Then, this research introduces an analysis environment to evaluate students automatically. The analysis environment collects dialog data from social network services and measures interactions among students in a team. After measuring interactions, the environment generates a report to visualize the team activities. We applied the proposed method and environment to the capstone design course to show the effectiveness of the method and environment. Based on the case study, the environment showed that the analysis method could easily indicate the teams' activities and check the level of participation.
