Public awareness of alien species can vary by generation, period, or specific events associated with these species. An understanding of public awareness is important for the management of alien species because differences in public awareness can affect the establishment and implementation of management plans. We analyzed digital texts on social media platforms, news articles, and internet search volumes used in conservation culturomics to understand public interest and sentiment regarding alien freshwater species. The number of tweets, number of news articles, and relative search volume to 11 freshwater alien species were extracted to determine public interest. Additionally, the trend over time, seasonal variability, and repetition period of these data were confirmed. We also calculated the sentiment score and analyzed public sentiment in the collected data using sentiment analysis based on text mining techniques. The American bullfrog, nutria, bluegill, and largemouth bass drew relatively more public interest than other species. Some species showed repeated patterns in the number of Twitter posts, media coverage, and internet searches found according to the specified periods. The text mining analysis results showed negative sentiments from most people regarding alien freshwater species. Particularly, negative sentiments increased over the years after alien species were designated as ecologically disturbing species.
The application of environmental DNA in the domestic ecosystem is also accelerating, but the processing and analysis of the produced data is limited, and doubts are raised about the reliability of the analyzed and produced biological taxa identification data, and the sample medium (target sample, water, air, sediment, Gastric contents, feces, etc.) and quantification and improvement of analysis methods are also needed. Therefore, in order to secure the reliability and accuracy of biodiversity research using the environmental DNA of the domestic ecosystem, it is a process of actively using the database accumulated through ecological taxonomy and undergoing verification procedures, and experts verifying the resolution of the data increased by gene sequence analysis. This is absolutely necessary. Environmental DNA research cannot be solved only by applying molecular biology technology, and interdisciplinary research cooperation such as ecology-taxa identification-genetics-informatics is important to secure the reliability of the produced data, and researchers dealing with various media can approach it together. It is an area in desperate need of an information sharing platform that can do this, and the speed of development will proceed rapidly, and the accumulated data is expected to grow as big data within a few years.

Objectives: The purpose of this study was to suggest the direction of the Healthy Village project for rural residents in accordance with the prolonged COVID-19 by investigating the digital environment for major health problems, the role of a health leader, necessary projects, and non-face-to-face projects for Healthy Village members in the COVID-19 epidemic. Methods: Telephone interview surveys were conducted with 585 residents from November 30, 2020 to December 21, 2020. Results: Health problems perceived by residents were in the order of concerns about infection (48.5%), depression (32.5%), difficulties in using medical services (9.4%), and lack of exercise (7.7%). The role of the health committee in the COVID-19 situation was "encouraging people to follow quarantine rules" with 91.3%. As a necessary health village project, there was a high demand for the provision of health products and mental health projects. 17.9% said that there is a computer or smart device connected to the Internet in their home, and 42.2% said that there is someone in the village who can easily get help if there is a problem in accessing and using Internet information. 36.9% were able to watch videos, and 22.2% were able to use the Internet through public facilities. Conclusion: In a public health crisis, where the provision of public health and medical services to rural residents is not smooth, it is necessary to manage health and quarantine through health leaders in the village, and it is required to establish a digital environment infrastructure that can conduct community participatory health village projects in a non-face-to-face environment.
In this study, we aimed to investigate the effect of Chinese gooseberry (kiwi)-based products on the improvement of intestinal function and constipation. In this study, 21 participants with no underlying disease and complaining of subjective constipation symptoms were selected. Through a pre-experimental design, the main effects, including the colon stagnation score and colon transit time, were assessed after the consumption of Chinese gooseberry (kiwi)-based products. To evaluate the side effects of this product, a subjective constipation assessment test was performed to analyze the degree of constipation improvement at an individual level. The results for the main effects revealed that the number of constipation groups was statistically significantly decreased, and the colon stagnation score and colon transit time were also reduced. Additionally, the participants' subjective constipation assessment test revealed a significant improvement in both intestinal function and bowel activity before and after the consumption of Chinese gooseberry (kiwi)-based products. Similar to the previously known kelp-, lactobacillus-, and fiber-based products, we showed that Chinese gooseberry (kiwi)-based products exert a significant effect on the improvement of the intestinal function and constipation. Furthermore, the results of this study provide valuable information for the development of healthy food products in the future that can help improve bowel movement. Moreover, Chinese gooseberry (kiwi) used in this study is not a functional food and is easily accessible. However, this study has several limitations as it is based on a pre-experimental design. Therefore, studies on randomized experimental and control groups are needed in the future.
The purpose of this study was to determine the hierarchical linear relationship among receptivity to organizational change, individual variables of professors and organizational variables in junior colleges. The population for this study was 12,920 professors in 139 junior colleges. Using random sampling method considering subject, 800 professors in 40 colleges were sampled for this study. The data were collected from May 26 to June 13. A total of 445 out of 800 questionnaires were returned of which 441 of 40 junior colleges were used for analysis after data cleaning. These data were analyzed by both descriptive statistics and One-way ANOVA with Random Effects, Ranmdom-Coefficients Regression Model, and Intercepts-and Slopes-as-Outcomes Model of hierarchical linear model(HLM). All data analysis was accomplished using the SPSS 20.0 for windows program and the HLM 6.0 for windows program. An alpha level of 0.05 was established priori for determining the significance. The findings of the study were as follows: First, the level of receptivity to organizational change of professions in junior college was 3.94. Second, 56.5% of total variance in receptivity to organizational change was individual level variance. 43.5% of total variance in receptivity to organizational change was organizational level variance. Third, personal valence about organizational change, psychological ownership, experience of assignment, years of service and job security had positive effects on receptivity to organizational change while years of service had negative effects on receptivity to organizational change. The effect of personal valence about organizational change was highest, and the effect of job security was lowest. Fourth, degree of organizational change, participative decision-making, group culture and accessibility of information related to organizational change had positive effects on receptivity to organizational change. The effect of degree of organizational change was highest, and the effect of accessibility of information related to organizational change was lowest.
This study examined the process of admission selection of vocational high schools and meister high schools and how the process have been utilized by schools to select appropriate students and by students to make decisions for application in consideration of their interests, aptitudes, and career paths. To address the purpose of this study, Focus Group Interviews(FGI) were conducted with three groups of participants: vocational high schools and meister high schools teachers, high school freshmen' parents, and middle school teachers who had many students advanced to vocational and meister high schools. The findings indicated that during the promotion process, schools made efforts to attract students with higher GAP and provided information mainly regarding employment rate instead of curriculum or program of majors. Since schools usually visited middle schools where higher GPA students were, not all students had balanced opportunities of high school promotions and enough information about majors. For the application process, the schools placed a high value on scholastic performance while students applied high schools considering their interests, aptitudes, and career paths. In terms of admission type and criteria, the high school teachers reported no big differences between special admission and general admission while students took advantage from the special admission process which was less competitive than general admission. Based on the findings, a number of suggestions were made in order to improve the process of admission selection of vocational high schools and meister high schools.
The historical value of the official documents of the Government General of Choson preserved as permanent archived documents has long been recognized. However, the fact that only parts of the overall documents were preserved and that the contents of the existing documents is not uniform, results in many problems regarding the evaluation and usage of such documents as archives. This study attempts to appraise a series of archival documents related to urban district planning compiled during the colonial era. Although limited in terms of its applicability to the development of an evaluation method for the official documents of the Government General of Choson as a whole, by evaluating the value of these documents based on the background of the documents produced during the Government General of Choson's implementation of its colonial policy, this study provides an important indicator of how such documents should be used in the future. On the other hand, the assessment of historical records such as the official documents of the Government General of Choson which have already been designated and preserved as permanent archived documents should not be perceived as an attempt to dispose of the relevant documents. With regard to the appraisal of historical archives, it is necessary to consider measures to link such documents with existing databases or information contents in order to heighten access to and usage of the relevant documents in the future.

To drive construction project successful, a construction manager with good competency is needed. In order to select appropriate construction manager, there should be a standard and a method for appropriately evaluating the competency of construction manager. There have been many researches on the competency of construction managers, but there are two points to be supplemented. One is that construction manager's competency measurement was not concrete and objective, and the other is that construction project performance directly reflects individual manager's performance. The purpose of this study is to derive a construction manager competency evaluation index by using the Notational Analysis technique that is used when deriving an indicator that measures the athlete's competency in sports. This analysis was drawn with Delphi method. Finally, the 'measurable behaviors'were derived that can evaluate the competency of construction managers. Through this, it is possible to express each manager's expertise, leadership, and personal characteristics in numerical expression. This will help decision makers when selecting construction managers. It is anticipated that decision makers will be able to make the decision to select the necessary construction managers easier because it can evaluate the construction managers through a scientific approach based on the record by supplementing the existing method which only relied on intuition.
The aim of this study was to investigate the short term effects of early intervention on alcohol knowledge, alcohol expectancies, drinking refusal self-efficacy for alcoholism prevention in adults and to examine its applicability in the field. This study was a non-equivalent control group pre-post quasi-experimental design. The participants were currently working, and were 12-25 points on result of the Alcohol Use Disorders Identification Test(AUDIT). The participants were a total of 25 men: 13 in the intervention group and 12 in the control group. The intervention group participated in early intervention program once a week for 4 weeks and the control group received only a booklet of alcohol related information. A chi-square test, t-test, Mann-Whitney U test were analyzed by using IBM SPSS Statistics 20.0. The intervention group had significantly higher the alcohol knowledge(t=1.258, p= .002), the negative alcohol expectancies(t=-1.346, p= .042), and the drinking refusal self-efficacy(t=2.817, p= .010) than the control group. In the future, it is need to apply the criteria of problem drinkers considering cultural characteristics, recruitment of participants, and motivational enhancement intervention using motivational interviewing. Especially, web-based alcohol related information providing program will help raise awareness of problem drinking. Early intervention program needs to be applied in community settings where problem drinkers are easily accessible.
