The photophone, Alexander Graham Bell's device for transmitting sound through light was patented in 1880. It included the transmitter modulating and reflecting strong light like sunlight to a distant receiver which produced sound. In this working of the photophone, the discovery of the sound-emitting effect under illumination was very essential. Longing for being famous in the scientific community, Bell focused on presenting various methods for producing sounds and for maximizing the loudness by performing intensive research on the photoacoustic effect. Bell's scientific research on photoacoustics was successful in establishing himself as a scientist and laid a foundation of photoacoustic analysis. And his invention became a basis for other researchers' subsequent technologies like fiber-optic communication.

Due to its role in maintaining the health of scientific societies, research ethics (or integrity) is notably receiving attention by academia, governments and even individuals who are not engaged in scientific researches. In this paper, I will introduce some valuable papers dealt with plagiarism as a representative research misconduct. In general, researcher's results that will soon be published must meet the crucial scientific criteria: originality, accuracy, reproducibility, precision and research ethics. The definition of plagiarism is "appropriation of another person's ideas, processes, results, or words without giving appropriate credit." Compared to fabrication and falcification, plagiarism is often considered as a minor misconduct. With intentionality, however, plagiarism can be corresponding to 'theft of intellectual product'. The context of plagiarism is not restricted to the stage of publication. It can be extended to prior stages of proposing (i.e. preparing the research proposal) and performing (executing the research), and reviewing (writing the review papers). Duplicate publication is regarded as a self-plagiarism in broad interpretation of plagiarism. To avoid dangers of plagiarism, earnest efforts from all members of scientific community are needed. First of all, researchers should keep 'transparency' and 'integrity' in their scientific works. Editorial board members and reviewers should keep fairness and well-deserved qualification. Government and research foundations must be willing to provide sufficient financial and policy support to the scientific societies; Up-graded editorial services, making good use of plagiarism detection tools, and thorough instruction on how to write a honest scientific paper will contribute to building up a healthy basis for scientific communities.

The natural environment plays an important role not only in ecological sustainability, but also in human health. Growing attention has been focused on the health benefits of natural environments with increasing scientific evidence in this field. Urban green space has positive effects on individual and community health; thus, it is considered as social infrastructure. The natural environment promotes mental health by relieving psychological stress and depression. Physical health can be improved by experiencing nature, which reduces physiological stress and boosts the immune system. Several international initiatives have been undertaken to improve our understanding in this field and to utilize these benefits for health promotion. Interdisciplinary approaches are needed to promote human health through the natural environment in the fields of science, education, planning and policy.

This article explores the potential learning materials and methods of science practice from exhibits, and how those are presented in natural history museums as a feasible science inquiry community. The idea of science inquiry community was offered as a form of science practice that ended with science learning. A grasp of 'scientific practice to learning' is understood as a way to conceive scientific methods as well as facts and understanding knowledge. To get educational implications on the scientific practice of 'earthquake' as a socioscientific topic in the communities, we analyzed 1) the relationship between earth science curriculum and exhibits related to 'earthquake', 2) the educational goals and intentions of educators, and 3) the characteristics of the exhibits in the American Museum of Natural History and in the Smithsonian National Museum of Natural History. The results of this study showed that those museums presented the exhibits consisting of various and practical cases and events of 'earthquakes' as a socioscientific topic related to their curriculum. At the target museum, it was clearly stated that the pursuing educational goals focused on relations with local interests and socioscientific issues. For making earthquakes relevant to visitors, delivering lived experiences with raw data and interactive media was emphasized in exhibit characteristics.

An assessment instrument dealing with secondary students' views on the nature of science was developed in this study. The features in aspects of the nature of science are generally accepted as characterizing the scientific enterprise and we have focused on are: 1) the purposes of the scientific enterprise, 2) the nature of scientific enquiry, 3) the nature and status of scientific knowledge, and 4) the nature and functioning of the scientific community. The questionnaire is made of three sections; that is, "Scientific Question", "Experiment", and "Belief". The Scientific Questions probe was designed to examine the ways in which learners mark out science as a particular domain, and particularly the types of questions that they think are open to scientific investigation. The Experiment probe was designed to throw light on the ways in which learners may think about theories and their relationship to evidence in a range of contexts. A related aim concerns the sorts of activities that learners consider to be experiments, and their reasons for this. The Belief probe was designed to see whether students are able to articulate the grounds for their acceptance of a proposition and, if they are, to explore the nature of these grounds. The reliability of the instrument developed in this study was found to be 0.86.

Motivated reasoning refers to biased reasoning that is affected by motivation to achieve a particular result or goal. In this study, we attempted a theoretical study on motivated reasoning that hinders the development of scientific thinking and empirical study on actual context of motivated reasoning in the research experiences of next-generation Korean researchers in the field of science and technology. To be specific, literature reviews were conducted to explore the psychological meaning of motivated reasoning and its negative impact on scientific thinking and science research. To understand the substantial meaning and context of motivated reasoning in the field of real science and technology research, we conducted in-depth interviews with eight graduate students and one young science and technology researcher. As a result of the literature reviews, we found out that motivated reasoning can interfere with the proper theory and data coordination, which is the core process of scientific thinking at the individual level. At the socio-cultural level, it can lead to cessation of constructing scientific knowledge and it can act as a mechanism in the process of using science for specific socio-cultural beliefs or purposes, thereby hindering the development of science and technology based on rationale and objective scientific thinking. Quantitative analysis with in-depth interview data showed that graduate students and the young researcher's experienced motivated reasoning results in trying to protect prior beliefs, make hasty conclusions, protecting socio-cultural belief or rationalizing decisions made by their community. Their motivated reasoning could become an obstacle in constructing valid science and technology knowledge through appropriate theory and evidence coordination. Based on these findings we discussed science education for improving scientific thinking.

We have developed and tested a prototype system to process transient alert messages from the currently working facilities such as Gaia and GCN notices. Our experiments with the prototype focus on developing a platform that can be used in the LSST era with about 10 million alerts per night and helping Korean community members with the automated processing environment to provide auxiliary information for every alert message. The system consists of a message broker implemented by Redis and multiple message subscribers specialized for specific scientific interests. The current implementation of the entire system allows new Korean members to adopt their own processing chains receiving the messages from our local broker. We welcome experimental ideas and opinions from the Korean community about the current message processing system. We plan to test the current system with the ZTF alerts in the near future.

The objectives of the study were 1) to make the reasonable standard, 2) to select the objective and scientific method and process for the location-allocation of a new provincial capital city. The Main standard of location-allocation were suggested as follows ; 1) Integration of province 2) Convenience of Administration service 3) Accomodations of new provincial capital city 4) Balanced development by region. The validity of location-allocation were reviewed the population potentials and nodal accessibilities. The population potential was examined to find the maximum point of administrative demand, and the locationallocation model was examined to find the minimum point of the aggregated travel-cost to a proposed provincial government office. The nodal accessibilities measured in travel-time distance and actual values. Two major concerns in locating public facilities are efficiency and equity.

The ongoing COVID-19 pandemic once again demonstrated how crucial it is to have unlimited access to scientific information. At the same time, the economic disparities that the pandemic revealed and aggravated made us realize that many of us cannot afford access to expert knowledge. While the international community is speculating about possible outcomes of the crisis, one can be said for sure, the pandemic accelerated many inevitable changes that would otherwise happen at a slower pace including increasing digitalization of the society and the expanding role of open data in the life of the academic community.

The rapid advances in genetic knowledge and technology raise various, sometimes unprecedented, ethical dilemmas in the scientific community as well as the public realm. To deal with these dilemmas, the international community has prepared and issued ethical standards in various formats. In this review, seven international standards regarding genetics and genomics will be briefly introduced in chronological order. Critical reflections on them will not be provided in this review, and naturally, they have their own problems and shortcomings. However, a common set of the principles expressed in them will be highlighted here, because they are still relevant, and many of them will be more relevant in the future. Some of the interesting contents will be selected and described. After that, the morality of one recent event related to whole-genome sequencing and person-identifiable genetic data will be explored based on those international standards.
