This study was designed to compare the understanding of ordinary elementary school students and scientifically gifted students about scientists. 473 fourth, fifth, and sixth graders in ordinary elementary schools and 40 students attending scientific educational institutions for the gifted were studied with the help of questionnaires and interviews. The survey showed that there were no significant differences between the two subject groups in relation to the external images of scientists. The subjects turned out to have low fixed external images. The scientifically gifted students had a better understanding of the internal images of scientists than ordinary elementary school students. Both the subject groups fumed out to be influenced by the press media and off-campus education, thinking that scientists served as inventors producing something useful in daily lift rather than as researchers studying natural phenomena or laws. It was found out that both groups admired Edison. The ordinary students respected Einstein and Jang Yeong-Sil whereas the scientifically gifted students respected Curie, Jug Yeong-Sil, and Nobel. The subjects admired them because of their achievements instead of their backgrounds or individual characteristics.

The Internet of Things (IoT) is one of the fastest technologies that are used in various applications and fields. The concept of IoT will not only be limited to the fields of scientific and technical life but will also gradually spread to become an essential part of our daily life and routine. Before, IoT was a complex term unknown to many, but soon it will become something common. IoT is a natural and indispensable routine in which smart devices and sensors are connected wirelessly or wired over the Internet to exchange and process data. With all the benefits and advantages offered by the IoT, it does not face many security and privacy challenges because the current traditional security protocols are not suitable for IoT technologies. In this paper, we presented a comprehensive survey of the latest studies from 2018 to 2021 related to the security of the IoT and the use of machine learning (ML) and deep learning and their applications in addressing security and privacy in the IoT. A description was initially presented, followed by a comprehensive overview of the IoT and its applications and the basic important safety requirements of confidentiality, integrity, and availability and its application in the IoT. Then we reviewed the attacks and challenges facing the IoT. We also focused on ML and its applications in addressing the security problem on the IoT.

Quantitative and qualitative research explore various social phenomena using different methods. However, there has been a tendency to treat quantitative studies using complicated statistical techniques as more scientific and superior, whereas relatively few qualitative studies have been conducted in the medical and healthcare fields. This review aimed to provide a proper understanding of qualitative research. This review examined the characteristics of quantitative and qualitative research to help researchers select the appropriate qualitative research methodology. Qualitative research is applicable in following cases: (1) when an exploratory approach is required on a topic that is not well known, (2) when something cannot be explained fully with quantitative research, (3) when it is necessary to newly present a specific view on a research topic that is difficult to explain with existing views, (4) when it is inappropriate to present the rationale or theoretical proposition for designing hypotheses, as in quantitative research, and (5) when conducting research that requires detailed descriptive writing with literary expressions. Qualitative research is conducted in the following order: (1) selection of a research topic and question, (2) selection of a theoretical framework and methods, (3) literature analysis, (4) selection of the research participants and data collection methods, (5) data analysis and description of findings, and (6) research validation. This review can contribute to the more active use of qualitative research in healthcare, and the findings are expected to instill a proper understanding of qualitative research in researchers who review qualitative research reports and papers.

In the perspective of hybrid, design contains confused forms and styles. Thus, the question is what 'decisively affects' on life, happiness and peace of human beings: In the past scientific ecology that tries to solve the problem in the aspect of functional design was important. Now the question is beyond the scientific ecology because human has a different way of environmental adaptation from animals. From this point of view, design is defined as something beyond materialistic standard. Terry Eagleton said, 'Creative ability deviating oneself and transcending is the very standard to measure human beings' A tendency to hybridize one's own section off genre or pursuing dismantlement is found on such creative perspective. In other words, it focuses on making a space of human's cultural behavior by unifying creatively natural environment and architecture space in the organic aspect. Such phenomenon provides a new chance and possibility in environmental design through a new molding experiment according to the development of digital technology. As experiments of environment design using digital technology are actively implemented, ecological and cultural views hybridize to create a new cultural space of various functions and features. Such experiment in environment design highlights the connections of ecological view, recognition of value, and relation-centered ideas, and enables a tool pursuing a new cultural development. This study focuses on the paradigm of such digital hybrid design and purposes to set the system by analyzing the application styles and principles of environment design through theoretical and case studies. In addition, it promotes a new possibility to develop environment design in the history of civilization.

The purpose of this study was to analyse the problems of 'Science Inquiry Experiment Contest(SIEC)' which was one of 8 programs of 'The 2nd Student Science Inquiry Olympic Meet(SSIOM)'. The results and conclusions of this study were as follows: 1. It needs to reconsider the role of practical work within science experiment because practical work skills form one of the mainstays in current science. But the assessment of students' laboratory skills in the contest was made little account of. It is necessary to remind of what it means to be 'good at science'. There are two aspects: knowing and doing. Both are important and, in certain respects, quite distinct. Doing science is more of a craft activity, relying more on craft skill and tacit knowledge than on the conscious application of explicit knowledge. Doing science is also divided into two aspects, 'process' and 'skill' by many science educators. 2. The report's and checklist's assessment items were overlapped. Therefore it was suggested that the checklist assessment items were set limit to the students' acts which can't be found in reports. It is important to identify those activities which produce a permanent assessable product, and those which do not. Skills connected with recording and reporting are likely to produce permanent evidence which can be evaluated after the experiment. Those connected with manipulative skills involving processes are more ephemeral and need to be assessed as they occur. The division of student's experimental skills will contribute to the accurate assess of student's scientific inquiry experimental ability. 3. There was a wide difference among the scores of one participant recorded by three evaluators. This means that there was no concrete discussion among the evaluators before the contest. Despite the items of the checklists were set by preparers of the contest experiments, the concrete discussions before the contest were necessary because students' experimental acts were very diverse. There is a variety of scientific skills. So it is necessary to assess the performance of individual students in a range of skills. But the most of the difficulties in the assessment of skills arise from the interaction between measurement and the use. To overcome the difficulties, not only must the mark needed for each skill be recorded, something which all examination groups obviously need, but also a description of the work that the student did when the skill was assessed must also be given, and not all groups need this. Fuller details must also be available for the purposes of moderation. This is a requirement for all students that there must be provision for samples of any end-product or other tangible form of evidence of candidates' work to be submitted for inspection. This is rather important if one is to be as fair as possible to students because, not only can this work be made available to moderators if necessary, but also it can be used to help in arriving at common standards among several evaluators, and in ensuring consistent standards from one evaluator over the assessment period. This need arises because there are problems associated with assessing different students on the same skill in different activities. 4. Most of the students' reports were assessed intuitively by the evaluators despite the assessment items were established concretely by preparers of the experiment. This result means that the evaluators were new to grasp the essence of the established assessment items of the experiment report and that the students' assessment scores were short of objectivity. Lastly, there are suggestions from the results and the conclusions. The students' experimental acts which were difficult to observe because they occur in a flash and which can be easily imitated should be excluded from the assessment items. Evaluators are likely to miss the time to observe the acts, and the students who are assessed later have more opportunity to practise the skill which is being assessed. It is necessary to be aware of these problems and try to reduce their influence or remove them. The skills and processes analysis has made a very useful checklist for scientific inquiry experiment assessment. But in itself it is of little value. It must be seen alongside the other vital attributes needed in the making of a good scientist, the affective aspects of commitment and confidence, the personal insights which come both through formal and informal learning, and the tacit knowledge that comes through experience, both structured and acquired in play. These four aspects must be continually interacting, in a flexible and individualistic way, throughout the scientific education of students. An increasing ability to be good at science, to be good at doing investigational practical work, will be gained through continually, successively, but often unpredictably, developing more experience, developing more insights, developing more skills, and producing more confidence and commitment.

The purpose of this study is to explore students' epistemic goals and considerations in designing an experiment task and to investigate how a shift in the students' epistemology affected their argumentation. Four 7th grade students were selected as a focus group. According to the results, when they designed their own experiment, their epistemic goal was 'scientific sense-making' and their epistemic considerations - the perception of the nature of the knowledge product was 'this experiment should explain how something happened', the perception of the justification was 'we need to use our interpretation of the data' and the perception of the audience was 'constructor' - contributed to designing their experiment actively. When students tried to select one argument, their epistemic goal shifted to 'winning a debate', showing 'my experiment is better than the others' with the perception of the audience, 'competitor'. Consequently, students only deprecated the limits of different experiment so that they did not explore the meaning of each experiment design deeply. Eventually, student A's experiment design was selected due to time restrictions. When they elaborated upon their result, their epistemic goal shifted to 'scientific sensemaking', reviewing 'how this experiment design is scientifically valid' through scientific justification - we need justification to make members accept it - acting as 'cooperator'. Consequently, all members engaged in a productive argumentation that led to the development of the group result. This study lays the foundation for future work on understanding students' epistemic goals and considerations to prompt productive argumentation in science classrooms.

In the 18th century, Xu Lingtai (徐靈胎) and Yoshimasu Todo (吉益東洞) were famous doctors advocating ancient medicine, though they lived in different countries, China and Japan. We compared their major books, analyzed their academic thoughts and then took conclusions as below. 1. The first, for instance "Classified Prescriptions of Treatise on Cold Damage Diseases, 傷寒論類方" and "Classified Assemblage of Prescriptions, 類聚方". Based on essential thought that a prescription and a syndrome should correspond, these books arranged and classified the Zhang Zhongjing (張仲景)'s texts."Classified Prescriptions of Treatise on Cold Damage Diseases", based on the thought that principles, methods, formulas and medicinals (理法方藥) were integrated in prescriptions, tried to find out the implicit treatment rules in prescriptions and syndromes through analyzing "Treatise on Cold Damage Diseases, 傷寒論". On the other hand, because Classified Assemblage of Prescriptions focused on the syndromes of ancient prescriptions (古方), it classified and collected the related texts of Treatise on Cold Damage Diseases and "Synopsis of Prescriptions of the Golden Chamber, 금궤요략", and then suggested only simple instructions on how to prescribe medicine. So in this book, the trend of experience was clear. 2. The second, there is "100 Kinds Records from Shennong's Classic of Materia Medica, 神農本草經百種錄" and "Description work of herbal pharmacology comprised of excerpts from Shanhanlun and medical experiences, 藥徵". Though both of these books are professional oriental pharmacology publications that advocate reactionism, there were remarkable differences in writing style between them. "Description work of herbal pharmacology comprised of excerpts from Shanhanlun and medical experiences" was based on "Treat on Cold Damage Diseases" and "Synopsis of Prescriptions of the Golden Chamber", just explained the effects of medications and discussed 'matter of course (所當然)', but not discussed 'the reason why (所以然)'. In explaining style of syndromes, it confirmed through research, and emphasized the inductive method. On the other hand, "100 Kinds Records from Shennong's Classic of Materia Medica based on "Shennong's Classic of Materia Medica, 神農本草經", explained the nature of medications and discussed 'the reason why (所以然)'. In explaining style of syndromes, it annotated and explained, and emphasized the process of reasoning. 3. The third, there is "Discuss the Headwaters of Medicine, 醫學源流論" and Severance of Medical evils, 醫斷". Aiming the then medical theories fallen in confused state, these books brought order out of chaos, clarified the categories of medical research, and emphasized the scientific method that could put theories into practice and verify them. The difference is that "Severance of Medical Evils" researched only macroscopic viewable clinical phenomena, and even denied the existence of names of diseases and etiological causes. Thus, it emphasized the accumulation of experiences, laid emphasis on "watching and realizing (目認)", and "understand and taking in (解悟)". Discuss the Headwaters of Medicine extremely emphasized the research of 'something not occuring (未然)', that is to say, induced notions of a disease from observing clinical phenomena, furthermore based on these, predicted the 'something not occuring (未然)' and emphasized researching 'the reason why (所以然)'. As regards how they deal with the traditional theories and post-Zhang Zhongjing's medicines, "Severance of Medical evils" took completely denying attitudes. In case of "Discuss the Headwaters of Medicine", it could be used reasonably through specific situation and detailed analysis. Collectively speaking, there were some differences between medical theories of Xu Lingtai and Yoshimasu Todo. Actually, these differences were whether he tried to research the essence of disease, whether he tried to consider it rationally, and how he treated various opinions occurring in the theories of traditional medicine and clinical experience.

It is not known that when and by whom 'The Lee's UmsikBup' was written. This cookbook is written purely in Korean and has not been published yet. There is another book named 'UmsikBup' in the cookbooks of the Chosun Dynasty and there are many books with similar names. So this book is tentatively named 'The Lee's UmsikBup'. This book comprises fifty three items, among which there are fifteen items of rice alcoholics, three items of Gook-Su (noodles), sixteen items of side dishes, seventeen items of Tuck (rice cakes) and Guaja(kookies), and two items of fruit punch and tea. Three items were illegible because the lines were erased or the letters were not clear. The cereals needed for making rice alcoholics were sixty four percent regular rice and thirty six percent sticky rice. As for the processes, the process using Jee-ae-bop took up fifty five percent. As for side dishes, pheasants, which are seldom used for food these days, were then popular for food. And the entrails of domestic animals were much used for food. Seeing that red pepper paste mixed with vinegar was used for steamed breams (Jim) and that red pepper was used for Yeolgooja Tang, we can estimate that this book was written after red pepper was introduced. Inferring that Chohong Chang (red pepper paste mixed with vinegar and honey) is found Jinchan Ye Que, we can estimate this book was written in the late 1800's. The cereals used for making rice cakes were ninety two percent sticky rice and eight percent regular rice. Sticky rice was much more used and pepper was used for making Tuck (rice cakes) as Hun Chal Byung, So Ham Byung and Dootum Tuck. The analysis of the terms used in this book revealed that 117 items were used for cooking processes. And it also showed us that there were six kinds of cutting and thirteen kinds of heating procedure. The shapes and sizes of foods were revealed on the basis of real things. The measuring units are hard to revive since the measurements were taken by the container then in use. Thirty four kinds of containers and cookers, twenty more of which are now in use, were used for preparing foods. The use of ‘twigs stretched for the east’ had no scientific base but said something of Korean folkways at that time.

This study aims to compare and analyze somatotype characteristics in clothing ergonomics as well as Sasang (Oriental physical constitution type classification into 4 kinds: taeyang, taeeum, soyang, soeum) medicine. The subjects were women collegians in their 20s. As a result, a new approach was made in somatotype classification. The following are conclusions: 1. The results of body measurement of the subjects belonged to 1 in most items when they were compared with the average records of female adults in their 20s in the national standard physique report. Thus, the subjects belonged to the average somatotype. 2. According to Sasang physical constitution classification, no subjects belonged to taeyang-type. Taeeum type (28.4%), had lower-body development greatest height and even development in width, thickness and girth. Soeum-type(37.8%) had the smallest physique. Soyang-type(33.8%) showed small values in height but great values in width, thickness and girth. 3. The factor analysis revealed 5 factors of somatotype characteristics: lower body factors including body weight, upper body factors, height factors including stature, belly width factors including waist and belly, and other factors comprising ankle and head size. 4. A cluster analysis by way of factor scores resulted in 3 types: cluster 1 44.6%, biggest values, largest somatotypes; cluster 2 17.6%, average somatotypes; cluster 3 tiniest somatotypes in most items. 5. In the crosstabs analysis, taeeum-type (57.6%) appeared a lot in cluster 1, soyang-type (76.9%) appeared most in cluster 2, and soeum-type (69.9%) was mostly seen in cluster 3. To sum up, the somatotype analysis of clothing ergonomics had something to do with constitution classification suggested in Sasang medicine. For clear justification, more systematic and scientific research should be followed with even more diverse subjects in sex and age.

The purposes of this study are to review research trends of applied geography field, to retrospect geographical works done by Korean geographers in applied geography, and to prospect the future of applied geography. We are in the period where societal problems such as energy, transportation, pollution, environment, health care, and many others, require careful consideration and need throughout strategies for solution. Most societal problems have some geographical dimensions. Because these problems are geographic in nature, there is an obvious implication that geography as a discipline has something to offer in their solutions. In fact, most geographic problems are best presented and analyzed through the applications of geographic theories, concepts and tools. Applied geography is a branch of general geography. It relies on the scientific methods and uses the principles and methods of pure geography. However applied geography is different in that it analyzes and evaluates real world action and planning and seeks to implement and manipulate environmental and spatial realities. Thus, geographic theories and other social theories that have geographic dimensions are fundamental to applied geography. Applied geography has a short history as theme in Korean geography. During the last two decades. Korea achieved remarkable economic growth. We have also encountered widening regional disparity, housing shortage of larger cities, transportation congestion, environmental pollution and many other problems. Applied geographers have tried to analyze and solve such spatial problems during the last 30 years. The research trend of Korean applied geography can be subdivided into 5 categories: (1) land use analysis and efficient utilization, (2) national physical development and planning. (3) regional development and regional planning, (4) tourism and location-allocation, transportation planning. Still the overconcentration of Seoul metropolitan region and unbalanced regional development are perceived to be the serious spatial problems which may induce more works to solve these problems. In Korea new emphasis has to be given to some professional training and experimental learning, including methodology, field techniques data management, statistical analysis, cartography, GIS, and other tools, as applicable and beneficial to problem solving in real world. The growth of applied geography depends on new insights and purposed solutions of future applied geographers in Korea. Applied geographers will contribute to the creation of future Korean geographies.
