Landscape impact assessment(LIA) is an aid to decision-making. For the decision maker, LIA provides a scientific examination of the predicted landscape implications of a proposed action and of the mitigation measures, before a decision is taken. Thus, the efficacy of LIA depends on the scientific credibility of the prediction and mitigation measures described in the landscape impact statement. The purpose of this paper was to examine the efficacy of LIA through the content analysis of prediction and mitigation measures in the selected 39 landscape impact statements and 34 environmental impact statements. The content of the selected statements was analyzed in terms of the quantification, precision, significance, and likelihood. The results showed that both prediction and mitigation measures were very low in the scientific credibility. Specifically, the prediction was ambiguously described without scientific probability, and the effect of mitigation measures was not specifically presented in the reports. Thus, landscape impact statement can not give credible information in the decision making process, which weakens the efficacy as an aid to decision-making. Based on the results, several suggestions were presented to enhance the efficacy of LIA.

Altmetrics is an emergent research area whereby social media is applied as a source of metrics to evaluate scientific impact. Recently, the interest in altmetrics has been growing. Traditional scientific impact evaluation indictors are based on the number of publications, citation counts and peer reviews of a researcher. As research publications were increasingly placed online, usage metrics as well as webometrics appeared. This paper explores the potential benefits of altmetrics and the deep relationship between each metrics. Firstly, we found a weak-to-medium correlation among the 11 altmetrics and visualized such correlation. Secondly, we conducted principal component analysis and exploratory factor analysis on altmetrics of social media, divided the 11 altmetrics into four feature sets, confirming the dispersion and relative concentration of altmetrics groups and developed the altmetrics evaluation model. We can use this model to evaluate the scientific impact of articles on social media.

This study examines how the project approach utilizing beans as the subject matter influences young children's scientific research capabilities and scientific attitudes. This examination ultimately aims at developing effective teaching methods and programs that can promote children's scientific research capabilities and scientific attitudes. Thirty six children at H kindergarten in Gunsan, Jeollabuk-do were selected as subjects of this study. The children aged five were divided into an experiment group and a comparison group, with eighteen for each group. Before the experiment, a pre-test was conducted on the children's scientific research capabilities and scientific attitudes. The pre-test results were subject to a t test to identify whether there were differences between the two groups in age as well as the levels of scientific research capabilities and attitudes. A post-test was also conducted to determine the differences between the two groups in these categories. These results have led to the conclusion that the project approach utilizing beans as the subject matter has a positive impact on improving young children's scientific research capabilities and scientific attitudes.

Background: Workers are exposed to several risks in academic laboratories due to the presence of potentially hazardous substances. The main objective of this study was to assess the prevalence of accident occurrence and associated risk factors among laboratory workers at the scientific laboratories of the public university in Lebanon and the impact of safety measures training and availability. Methods: In this observational study, a survey was conducted for one year in scientific laboratories at faculties of the public university. Results: Among the participants (N = 220), 45.0% have had accidents; the main cause was exposure to chemicals (73.7%) and more specifically by inhalation (45.4%). Females (85.9%) were more exposed to accidents than males. Laboratory workers with a master's degree, a full-time schedule, and more than ten years of experience were significantly more exposed to accidents (p < 0.05). A significant association was found between accident occurrence and training on management of hazardous products (p = 0.044), risks related to workplace (p = 0.030), eyewash and emergency shower (p < 0.001), first aid (p = 0.012), and facial protection availability (p = 0.019). In spite of the lack of safety culture and efficient training on laboratory safety, participants have shown a very good perception regarding safety measures to be applied in case of work accidents. Conclusion: Based on our findings, the prevalence of accident occurrence is elevated among lab workers at the public university. The impact of regular training on laboratory safety preventive measures is of great importance to ensure the efficiency of occupational health and safety in scientific laboratories.

Although invasive alien species (IAS) have a negative impact on native ecosystems and reduce ecosystem services and productivity, the understanding of IAS at the population level is still lacking. Coreopsis lanceolata, a perennial plant native to North America, is expanding its invasive range, but there is limited research on the invasion risk of this species, and measures to control its spread are inadequate. Therefore, we collected findings from selected studies on C. lanceolata, examining its morphological and growth characteristics, reproductive traits, and invasion strategies, sourced from scientific databases using its scientific name as the keyword. Researchers have conducted extensive research on C. lanceolata, primarily focusing on the extraction of chemical compounds for anticancer and antioxidant effects and numerous studies on seed germination conditions in the field of ecology. Coreopsis lanceolata has a negative impact on plant ecosystems in Australia and Japan, and its high invasiveness is associated with high seed production, high seed viability and longevity, rapid reproduction through rhizomes, high surface coverage, and long flowering periods. Few studies have examined the invasive potential of C. lanceolate and management techniques to stop its spread, despite worries about the detrimental effects of invasion on plant ecosystems. Therefore, additional research on the invasion risk and management of C. lanceolata is necessary. This review offers a thorough analysis of C. lanceolata, serving as a scientific foundation for devising future ecosystem management strategies.

In case of executing surveys in marine ecosystems, the most important things are scientific selection measures of survey stations that can represent various ecosystems characteristics in subjected areas. The situations show a lot of differences that understand characteristics of marine ecosystems in targeted areas according to selection methods and positions in survey stations. Investigation ranges and station numbers in marine ecosystems are classified according to project characteristics and scales. But, currently a clear divisions or objective standards are not. Therefore, this study tried to provide selection measures of survey station in scientific and objective marine ecosystems through precise analysis among environmental impact statements of coastal development projects until now. In this study, impact scopes of marine ecosystems correspond to physical impact predictions by undertaking projects. Impact ranges were divided into three(physical impact ranges) coastal waters. In case of proposing numbers of survey stations according to this survey ranges, numbers of investigation stations due to minimum survey scopes in targeted projects applied 20~30% of all numbers in survey stations. Number of survey stations due to average investigation scopes within physical impact ranges applied 60~70% of all numbers in investigation stations. Numbers of survey stations due to maximum survey ranges within physical impact scopes applied 10~20% of all numbers in survey stations. So, improvement measures were deducted. Finally, according to prediction ranges in impact of various coastal development projects, several kinds of conclusions are suggested. And, it is thought to be able to use as fundamental database to select investigation stations in marine organisms through this study.
