The purpose of this study was to identify how young children conceptualize living things and nonliving things. For this study, a total of 465 young children was sampled in Krea, and a questionnaire of paper test was administered to them. The results were as follows. 1. More than 80% of young children recognized dogs and dandelions as living things, but less than 60% of children recognized bird's eggs and chestnuts as living things. 2. Mostly, young children's ability to distinguish exactly between living things and nonliving things improved by increasing grade level. 3. Criteria to distinguish about living things and nonliving things are firstly to be mobilized and secondly to be breathed.

The purpose of this study was to analyze pre-school teachers' observation experience and their pre and post degrees of preferences in observing underground and water living things, fungus, insects, flowerless plants and sea lives. Based on the analysis, their pre-observation experience in living things were insects, ocean creatures, underground living things, flowerless plants, fungus and water living things in order. The degree of preferences in flowerless plans based on their gender, the female pre-service teachers showed higher scores than the average in both pre and post test. The male, however, responded higher scores in underground living things in both tests. Their background such as liberal arts or science or arts and physical major affected their preferences scores in water living things, insects and flowerless plans in the post test, and the science major pre-service teachers showed the highest degree of preferences in insects among the liberal arts, science or arts and physical major pre-teachers in the post test. In conclusion, there were different degree of their preferences affected by the pre observation experience, gender difference, their present majors such as the liberal arts, science or arts and physical major, the categories of living things but not in their high school background such as liberal arts or science.

When we discuss the literature of traditional era in view of ecological mode, Saseol sijo and its common writers were not objects of interests because they were thought only as having the view of the world or nature the same as the noble class and their normal sijo writings had. Also the living things in Saseol sijo were not paid attention to. They were ignored and degraded because they were unfittable and unnatural poetic diction, or they were nonpoetic results of objects. Any critics could not recognize the breathing things as 'the living ones' or 'the subjective things' in the text. In Saseol sijo, the appearance of experienced, substantial and usual animals attract our interest, which is a clue to compare the noble class' sijo with having the ideal and imaginary living things. This study discussed the writer's view and recognition of 'the living things' in Saseol sijo. In this essay 'the living things' mean living and moving creatures. First 'the living things' in Saseol sijo were the creatures of daily life and experience. They were not ideal or dreamy creatures any longer to the writers of Saseol sijo. In Saseol sijo it's possible for creatures which ecological symbiosis cannot be made to appear together. On the contrary there are texts which had outstanding recognition of 'the living things' that were accustomed to the human life. The writers of Saseol sijo understood 'the living things' as creatures familiar to human beings. Their warm and affectionate eyes toward the creatures made 'the living things' the objects of identification and sympathy. There are some works which were complicated with love and hatred toward 'the living things'. In conclusion, the life of Saseol sijo writers were the same as the symbiosis with the living creatures.

This study aims to analyze science-gifted elementary students' understanding of 'Living Things' with ontological domains. As research subjects, this study selected 80 science-gifted students who belonged to Education Institute for Science-gifted Elementary Students at University of Education, and this study came to the following conclusions. Firstly, the gifted students thought of animals as living things most, out of which humans accounted for the highest rate. They were also found to evaluate the importance of living things depending on benefits and harms to humans. Secondly, when judging 4 domains of living things, animals, plants, static inanimate objects and dynamic inanimate objects, the gifted students did not have difficulty judging animals, plants and static inanimate objects, but 4 of them judged the moon, a dynamic inanimate object, as a living thing. In the aspect of reaction time, they spent more time judging plants than animals. This study classified their standards of judgement on living things into ontological categories. As a result, it was found that 31 and 33 out of them had standards of judgement corresponding to the category of matter and the category of process respectively, and only 16 of them had standards of judgement corresponding to the category of mental states. Thirdly, how to make a waterwheel and images of euglena and paramecium were shown to 10 of the gifted students who suggested simple movements as characteristics of living things. As a result, 7 of them changed their standards of judgement from the category of matter to the category of process, while 3 of them changed from the category of matter to the category of mental states.

The aims of this study were to investigate the differences of the proportion of misconceptions and the reasons for selecting responses related to questions about small living things between talented and average students. The study subjects were made up of three groups. They were a class of 37 talented elementary students in science attending J National University of Education, a class of 37 talented students in science attending J City Office of Education, and a class of 33 average students attending J City. A questionnaire was composed of 20 test questions for examination of concepts related to small living things. The data obtained in this study was analyzed using a statistical program. The major results were as follows: In general, the level of the scientific concepts possessed by the talented students was much higher than that of the average students, especially in question 14. The reasons for the misconceptions which were revealed through this study were classified into vagueness of the language used, hasty decision and deduction making, using the wrong analogical inference, mass communications (TV or internet) and experimental differences between individuals. In terms of the reasons for the selection of a given response, the talented students had also a higher frequency in the 'science books for children' category than the average students, indicating that various kinds of science books for children have an influence on the formation of concepts on small living things. The misconception proportion of male students was 5.4% higher than that of female students in mean frequencies of all questions, although the difference was not statistically significant except for question 4. Data from this study may help teachers involved in education for gifted students to reconsider their conceptions on small living things.

Recent advances in medical science have made people live longer, which has affected many aspects of life, such as caregiver burden, increasing cost of healthcare, increasing number of disabled and depressive disorder persons, and so on. Researchers are now focused on elderly living assistance services in smart home environments. In recent years, assisted living technologies have rapidly grown due to a faster growing aging society. Many smart devices are now interconnected within the home network environment and such a home setup supports collaborations between those devices based on the Internet of Things (IoT). One of the major challenges in providing elderly living assistance services is to consider each individual's requirements of different needs. In order to solve this, the virtualization of physical things, as well as the collaboration and composition of services provided by these physical things should be considered. In order to meet these challenges, Web of Objects (WoO) focuses on the implementation aspects of IoT to bring the assorted real world objects with the web applications. We proposed a semantic modelling technique for manual and semi-automated service composition. The aim of this work is to propose a framework to enable RESTful web services composition using semantic ontology for elderly living assistance services creation in WoO based smart home environment.

Purpose: The purpose of this study was to explore and understand life and meaning in life of elementary school students. Methods: Data from 1,790 higher grade elementary school students were analyzed for content of meaning in life. Results: The students described the following: 1) Meanings of living existence included, 'living things', 'importance', 'human life', 'family', 'event', 'eternity', 'origin of life', 'disease', and, 'protection'. 2) Four categories were found for reasons why human life is important, 'solitary', 'limitation', 'valuables', and 'living'. 3) Things that one can do to protect the value of human life were, 'doing safely', 'keep things well', 'altruistic behavior', 'doing sound activity', 'preservation & development', and 'devotion of oneself'. 4) Meaning of life included 'to accomplish plans', and 'to do things' 5) Cases when students felt life had meaning were 'perform meaningful behavior', 'comfortable emotionally', and 'receiving help from others'. 6) The methods by which to live a meaningful life were 'working diligently', 'serving', and 'doing rightly'. Conclusion: These results suggest that students recognize the meaning of life in a most positive way and with a relatively wide scope, but as a few students had a negative orientation, age-appropriate and more systematic education programs are needed.

This study analyzed the effects of 'app-based learning of observing and recording living things' on elementary school students' science-related attitudes. Samples of the study were composed of 24 sixth-grade students attending the science club of N elementary school in Seoul, Korea. The learning was conducted for 12 times over 7 months. 'TOSRA(Test of science-related attitude)' was used to quantitatively analyze the science-related attitudes of elementary school students. To find out more detailed characteristics, records of interview were also gathered and analyzed. The main results of this study are as follows. First, for the paired t-test of science-related attitudes, a statistically significant difference between the pre and post was found. As results of the interview, it was revealed that 'experiences of outdoor activities' greatly influenced the increase of science-related attitudes of the students. Second, in ANCOVA, according to 'gender' there was no statistically significant difference in score of science-related attitudes. But, there was statistically significant difference in science-related attitudes according to 'preferred science subjects' and 'whether individual interest has occurred about observing and recording living'. Based on the results of this study, implications for research of elementary biology education are discussed.

Using the concepts on the need of existence of living things, we investigate students' concepts on interdependence concepts between living things. The purposes of this study are to identify components of conceptual ecologies influencing on students' concepts and to describe the relations between those components and their concepts. The subjects of this study are 4 boys, 2 girls in the 3rd grade of middle school. The sources of data used in this study include a questionnaire, interviews and observation of the discussion class. Then, all data collected through each methods are compared and summarized in the relation to the questions of research. As a conclusion, it reveals that students' concepts are connected with several cognitive or affective components. Especially, the major components influencing on students' concepts are their metaphysical beliefs, conceptions includes other fields. These components function as constraints. Given these results, a teacher who want to teach a new concept to students should consider their characteristics and the components of conceptual ecology.
