The purpose of this study was to develop and apply the pro-environmental housing life educational program to improve of pro-environmental attitude for upper grade of elementary school and to verify its effectiveness and influence. To achieve the purpose, documentary and investigatory research was conducted and thereafter the program developed and implemented following 5 stages of analysis, design, development, implement and evaluation. The experiment was made progress as two-group pretest-posttest design, and the program was applied to a class for two hours every week in discretionary activity class for 6 weeks. A reconstructed questionnaire through Kim et al.(2000)'s test tool was used to survey the effects of students's attitudes on environment. The major results were as follows. First, the developed program focused on the main contents of pro-environmental housing life based on ESD. Second, this program had a positive effect on elementary school students' environmental attitude. Third, this program had a positive correlation(.588~.712) among the 3 subdomains of verbal commitment, actual commitment and affect. Fourth, according to qualitative analysis, students appear to be more concerned and interested in the pro-environmental housing life and environmental problem. In conclusion, the pro-environmental housing life educational program based ESD has a positive effect on elementary school students' environmental attitude. Therefore, more intensive research and follow-up study on teaching and learning methods should be highly considered.

The purpose of this study is to examine the effect of the disability awareness program and to search for its development plan. For this, the disability awareness program was developed and lecturers were educated. And it had been exercised and examined its effect to 508 people including elementary, middle and high school students and adults nationwide from June to October in 2017. To examine the effect of the program, Disability Awareness Index developed by Korean Foundation for Persons with Disabilities was used. It was also examined on the change of the disability awareness(understanding disability and human rights of disabled) and of the knowledge about discrimination and differentiation. Pre-post tests based on the experimental design were performed and data were analyzed using descriptive statistics, paired t-test, independent t-test and ANOVA. The research results showed as follows; Disability awareness was improved significantly and knowledge about discrimination and differentiation were enhanced after attending the program. Also, it was found that the factors like gender, age, and program types made significant difference to the effects of the program. Based on the research results, this study suggested for the development disability awareness program and the directions for future studies.

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.

Salicylic acid(SA) is a phytohormone that is related to plant defense mechanism. The SA accumulation is triggered by abiotic and biotic stresses. SA acts as a signal molecular compound mediating systemic acquired resistance and hypersensitive response in plant. Although the role of SA has been studied extensively, an understanding of the SA regulatory mechanism is still lacking in plants. In order to comprehend SA regulatory mechanism, we have been transformed with a SID2 promoter:GUS::LUC fusion construct into siz1-2 mutant and wild plant(Col-0). SIZ1 encodes SUMO E3 ligase and negatively regulates SA accumulation in plants. SID2(SALICYLIC ACID INDUCTION DEFICIENT2) is a crucial enzyme of SA biosynthesis. The Arabidopsis SID2 gene encodes isochorismate synthase(ICS) that controls SA level by conversion of chorismate to isochorismate. We compared the regulation of SID2 in wild-type and siz1-2 transgenic plants that express SID2 promoter:GUS::LUC constructs respectively. The expressions of $\beta$-GLUCURONIDASE and LUCIFERASE were higher in siz 1-2 transgenic plant without any stress treatment. SID2 promoter:GUS::LUC/siz1-2 transgenic plant will be used as a starting material for isolation of siz1-2 suppressor mutants and genes involved in SA-mediated stress signaling pathway.

The inflammatory response have been considered as one of important targets for cancer treatment because they play a key role during all steps of tumor development including initiation, promotion, malignant conversion and progression. To investigate the anti-inflammatory response during anti-tumor activity of an aqueous extracts of Ecklonia cava (AEC), alterations on the distribution of mast cells and the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), nuclear factor (NF)-κB, inflammasome compositional protein and inflammatory cytokines were examined in CT26 colon tumor-bearing BALB/cKorl syngeneic mice after administrating AEC for five weeks. After treatment of AEC, total weight of tumor and necrotic region of tumor section were significantly decreased compared to vehicle treated group. The number of infiltered mast cells was higher in AEC treated group than vehicle treated group, while the expression levels of COX-2 and iNOS were decreased in AEC treated group. Also, similar decrease pattern were detected in the expression levels of NF-κB, NLR family pyrin domain containing 3 (NLRP3), apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) and caspase-1 (Cas-1) after AEC treatment although the decrease rate was varied. Furthermore, the mRNA expressions of three inflammatory cytokines including tumor necrosis factor-α (TNF-α), interleukin-1α (IL-1α) and interleukin-6 (IL-6) were remarkably decreased in AEC treated group compared to vehicle treated group. These results suggest that inhibition of inflammatory response may be tightly associated with anti-tumor activity of AEC in CT26 colon tumor-bearing BALB/cKorl syngeneic mice.

In this research an induction motor vector control system was developed using Simulink and RTW(Real Time Workshop). On the Simulink window, control system is designed in the form of block diagrams, program codes are produced automatically with the RTW, then c compiler compiles the program codes. With this automatic real time program producing mechanism rapid prototyping is realized without the time-consuming manual program coding procedures. To show effectiveness of the proposed designing scheme a DSP-based induction motor vector control system was constructed and implemented
