  • This paper is written in order to investigate how Lee Je-Ma changed traditional Zhu Xi's philosophical view on Way(Tao; 道) Virtue(De: 德) Nature(Xing;性) and Imperative(Ming; 命), which was general concepts of his contemporary age, to practical philosophy and created new medical theories of Sasang(4 symbols) science from it. Lee emphasized the true thing which is able to be done in one's living not the concepts of Sasang. So he induced the concepts of Way and Virtue from the easy and simple way(易簡之道) in the Classic of Changes(I'Ching) for the purpose of practice by anyone. Because Nature and Imperative are derived from Way and Virtue in the context logically, human life is virtual in itself, so the substance of Nature and Imperative became equal with Way and Virtue. Herein the names and concepts of original 'Sasang' were substituted to Business(事), Mind(心), Body(身), Thing(物) which is able to be directly related with human being in his daily life. And he explained variously about the responses of Mind and Body of individuals onto Business and Thing. So it could be applied in medical aspects like emotional, symptomatical, characteristic features. Conclusively man is virtual being, so Nature and Imperative in the level of Human being are based on Way and Virtue in the level of Heaven. For that reason the new concepts of Sasang Business. Mind. Body Thing or Heaven. Human. Nature and Imperative were proposed.

  • In this study, we investigated the effects of explicit and reflective instruction about nature of science (NOS) using episodes from the history of science upon students' understanding about NOS, achievement, and enjoyment of science lessons. Four classes of ninth graders (N=129) at a coed middle school were divided into the control and the treatment groups. The students were taught about the composition of material for 11 classes. Before the instruction, most of the students in both the control and the treatment groups held naive views about NOS. After the instructions, the views about NOS of the control group students did not change, whereas the students in the treatment group held more adequate views about NOS. The high-level students in the treatment group showed more adequate views about NOS than the low-level students. However, there were no significant differences between the test scores of the two groups in the achievement and the enjoyment of science lessons.

  • Major statutory nature protection areas include Nature Parks, Nature Reserves. Nature Ecological System Protected Areas. Biosphere Reserves, Nature Protected Forests, Wildlife Sanctuaries, and Protection Forests with total area of 1,124,000 ha. These protected areas cover almost 18% of the forested area. The number of visitors of NPs reached over 33 million per year with sharp increasing rate over the years. To protect the deteriorated hiking trails and camp grounds caused by overuse, two management policies have been implemented : cooking prohibition and natural rest rotation system. While prohibition of cooking is based on the fact that most of the solid wastes in nature parks are leftovers of cooking, natural rest rotation system is mainly for rehabilitation of deteriorated areas by natural processes. The system has closed 47 trails(in 27 mountains) throughout the country since January 1991, which is scheduled to continue 3 years. Due to the lack of accumulated scientific knowledge on how, when and where to close, application of the system leaves much to be desired. This paper discusses the current efforts to protect the natural resources for recreational use and suggests future directions for an effective policy implementation.

  • The effects of high vanillin concentration on fresh-cut apples treated with NatureSealTM were investigated Apples were sliced, treated with 6% NatureSealTM or 6% NatureSealTM + 120 mM vanillin, packaged in polyethylene bags, and stored for 3 weeks at 4C. The L value, soluble solid level and titratable acidity of fresh-cut apples treated with NatureSealTM + 120 mM vanillin during storage were lower than those of fresh-cut apples treated with NatureSealTMonly; the growth of total aerobic bacteria, yeast and molds were also more inhibited in fresh-cut apples treated with NatureSealTM + 120 mM vanillin. These results show that the addition of 120 mM vanillin inhibits the growth of microorganism but 1m detrimental effects on the quality characteristics of fresh-cut apples treated with NatureSealTM.

  • This study aimed to develop a program that can be linked to gardening education activities in elementary students' curriculums and creative experience learning courses, and to apply the developed program to 6th graders in an elementary school located in Seoul. Research was conducted in a large category called biophilia, which named the instinct of human nature and nature throughout the research. The curriculum revised in 2015 was selected for the purpose of the garden education program based on the objectives and contents of the unit, and for the purpose of the class. In the process of developing and implementing the program, experience properties and elements were divided into direct and indirect experience of nature, including shapes and forms found in nature, air, water, plants, weather, animals, and natural materials. The results showed that the biophilic horticultural education program was effective in promoting students' multi senses. In the case of the experimental group, all the multi-sensory areas showed statistically significant differences, especially in the area of environmental literacy, environmental effect and emotional balance including plant cultivation knowledge. There was a relatively smaller difference in the dietary effect area than other areas because of no directional dietary program was included in the developed program. As a result, first, it is expected that the data can be utilized on site as a program or place of activity for students in upper grades. Second, it will be necessary to develop a more diverse program using other biophilic elements that were not covered in this study in order to maximize the effects of biophilic education.

  • In this study, we investigated the effects of small group discussion using episodes from the history of science on students' understanding about the nature of science (NOS), achievement, enjoyment of science lessons, and science learning motivation. Participants were 138 ninth graders from a middle school in Seoul and they were assigned to a control group and a treatment group. Students in the treatment group were provided with two contrasting perspectives concerning the NOS and were encouraged to discuss them in small groups. The intervention lasted for 5 class periods. The results revealed that students of both the control group and the treatment group were found to possess similar views about NOS in a NOS pretest, whereas students of the treatment group exhibited more sophisticated understanding in a NOS posttest. The scores of the treatment group were also significantly higher than those of the control group in an enjoyment of science lessons test and a learning motivation test. However, there was no significant difference between two groups in the achievement test scores.

  • This study estimates the correlation dimensions of the land-sea breeze phenomenon, that has a clear diurnal cycle, in order to gain a more detailed understanding of this phenomenon. The data adopted include north-south wind velocity component(v) and temperature(T) time series that were observed at Kimhae Airport and Inje University over a period of 5 days, from the 4th to the 8th of August, 1994. The embedding phase space of the time series were reconstructed from 2 to 14 dimensions, and the correlation dimensions of the attractors were then estimated. The results show that the land-sea breeze phenomenon exhibits a deterministic chaos with non-integer correlation dimension values between 2 and 3. Accordingly, 3 is the minimum number of independent variables required to model the dynamics of the landsea breeze phenomenon in the Kimhae area. Since the saturated embedding dimension, when the correlation dimension remains unchanged, is larger for the wind velocity v-component than for temperature, this indicates that wind velocity is susceptible to topology.

  • Floods are the most common natural disasters and are annually causing severe destructions worldwide. Human activities, along with expected increased extreme precipitation patterns as a result of climate change enhance the future potential of floods. There are proven evidence that infrastructure based responses to flood disaster is no longer achieving optimum mitigation and have created a false sense of security. Nature-based solutions(NBS) is a widely accepted sustainable and efficient approach for disaster risk reduction and involves the protection, restoration, or management of natural and semi-natural ecosystems to tackle the climate and natural crisis. Adoption of NBS in decision-making, especially in developing nations is limited due to a lack of sufficient scenario-based studies, research, and technical knowledge. This study explores the knowledge gap and challenges on NBS adoption with case study of developing nation, specially for flood management, by the study of multiple scenario analysis in the context of climate, land-use change, and policies. Identification and quantification of the strength of natural ecosystems for flood resilience and water management can help to prioritize NBS in policymaking leading to sustainable measures for integrated flood management.

  • Recent environmental issues such as genetically modified organisms, the loss of biodiversity, climate change, and nuclear waste cannot be reduced to a matter of science or society and explained through nature-society dualist approaches because of their complexity and heterogeneity. This paper examines how nature-society dualism has been embedded in science studies and geography and how this dualism can be overcome. Actor-Network Theory as an attempt to overcome this nature-society dualism is appropriate in analysing "strange imbriglio" of biology, politics, technoscience, market, value, ethics and facts that constitute our society by focusing on heterogeneous association, and can contribute to providing a useful framework to solve environmental problems.
