This study collects and analyzes data on educational philosophy and method for domestic and overseas alternative schools. This information is then applied to educational purpose and curriculum for a home economics curriculum that develops unique characteristics for Korean alternative education.This study collected and analyzed the characteristics of educational content and educational elements from two renowned alternative schools: Waldorf School in Germany and Summer Hill in the United Kingdom. The research results were as follows. First, it is necessary to create new word instead of using the term 'alternative education'. Second, among characteristics of Korean home economics curriculum, 'practical problem-solving ability', 'independent living ability', and 'relation forming ability' should be utilized to create a school with an independent curriculum and to establish a unique brand value. Third, time investment on instructor education should be made to cultivate competent and charming instructors as the center of a school. Lastly, school education should manage student's life at school and after graduation. The school and instructor should provide alternative education while thinking they are responsible for 50 years of a student's future life. This study helps show that alternative education is not perceived as a superficial and generalized education and that Korean alternative education can find similar characteristic to those of overseas cases.

Ministry of Education and Human Resources presented on December, 2006, 'Alternative school establishment and operation regulation' of contents that can be recognized attainments in scholarship because is authorized if alternative schools fulfill fixed condition. Even though, one time, it was true that several opinions which try to limit to adaptation school of person disqualified for school, thus, various discussion and efforts that specialized school for alternative education does to grow are appearing. However, the expectation which a lot of non authorized schools will apply is not so high because specialized school for alternative education will be controlled in free curriculum and school operation that have been administered and can not be guaranteed school's sell-regulation if acquire legal authorization. Under such social and educational background I surveyed present condition, law, system, literature investigation of existing study, Japanese system and example and authorized two sample specification schools etc. through 'A Basic Study on the Optimum Facilities Criteria Modeling of Regional Specialized Schools for Alternative Education(2006. 10)'. This study was preceded the succession and I visited 17 schools that permit investigation opening of schools among 29 that is authorized until present. So I try to find out architectural planning criteria to activate specialized school for alternative education more through analyzing school's general present condition, establishment idea, operation and specialized education plan, facilities present condition and characteristic.

The purpose of this study was to investigate pre-service elementary school teachers' understanding about alternative energy and to identify their alternative conceptions. The two-tier instrument had been developed by Cheong et al. (2015) were used for this study. Twelve items from the instrument consisted of four categories: 'source of alternative energy', 'greenhouse gas emission', 'cost in electricity and construction' and 'advantages and disadvantages'. One hundred and fifteen pre-service elementary school teachers were participated in online survey during the semester. The results analyzed using SPSS 26.0. were as follows: First, the correct response rate varied depending on the content of item. Items related to characteristics and advantages & disadvantages of alternative energy showed high percentage of correct answers. Whereas, items regarding the principles of alternative energy showed relatively low percentage of correct answers. Second, there are some items showing statistically meaningful differences according to students' high school track. Nevertheless, there are no significant differences in overall. Third, we identified twelve alternative conceptions about alternative energy from students' answer distribution. Educational implications were discussed based on the results.

From the mid-1990s, the discussion on alternative schools began in earnest, and with the increasing interests in them, Korean parents' association of alternative education, KPAAE was launched formally in November, 2008. Among the alternative schools in the nation, thirteen urban alternative schools were studied and analyzed. The result indicated that they are being run by individuals and civic organizations with no approval and the facilities and spatial organization of the schools are poor, which is thought to be mainly due to financial reasons as well as the schools' educational goal that puts emphasis on experiences leading to utilize outside local facilities. With this background, the results from the analysis of the facility status and the spatial organization of urban alternative schools led us to understand the followings: First, it showed that per capita average of area of the urban alternative school is approximately 11.995m$^2$, less than 14N, the standard area of institutional schools. Second, depending on the form of facilities, the space of other facilities is shared to make up for insufficient space, and is utilized to a small degree and for multi-purposes. Third, the space reflects the disposition of subject students, and is located in the area with convenient traffic for students' attending the schools conveniently. Fourth, specialized space is run on the basis of educational goals, and the exploring of career and the improving of sociality are pursued through internship programs associated with local facilities. Thus, it is desirable for the minimum per capita area of the urban alternative school to meet 14N, the standard area of the institutional schools in order that the urban alternative school may overcome the spatial limitation and the financial hardship stemming from the practically difficult constructing of new buildings and the small scale operation, and it may make flexible use of the space, and the students may live their lives smoothly. Also, it is thought that for the activating of the urban alternative schools, the plans for utilizing various facilities associated with local facilities should be considered.

Educational environment that change rapidly, trial and error of system, breakdown of school environment by this and private education expense increase etc. are big social problem that we are facing present. Government is enforcing recognizing these problems and develops various program but the change and expansion of school facilities to achieve various program such as those are still unprepared. Now, important agenda that is lifelong education concept that is always can reeducate with social problem such as school leaving is come to the fore. So, specification high school for vocational education and alternative education cope in educational system and educational environment that is changed newly in existent school system. As the beginning step of the purpose of research, this study compares the attempt of school types and change of the school operation system for alternative education by between Korea and Japan and survey some regional cases. And the specification high school for alternative education which correspond to changed educational environment newly and architectural planning of educational facility that can activate those will be done. Also, this study aims that propose basic data that raise school facilities and educational environment by establishing guide line of optimum facilities for specification high school that wish to reorganize again or establish newly using existent school facilities and presents.

Kojongsi persimmon (Diospyros kaki) is the major cultivar of astringent persimmon in southern of Korea. Kojongsi persimmon leaf has been traditionally used for acute and chronic diseases in Oriental countries. The purpose of this study was undertaken to investigate the antioxidative activities of the extract of Kojongsi persimmon leaf during growth. We investigated the antioxidant effects of the persimmon leaf extracts during growth on total polyphenol, total flavonoid, electronic donating ability (DPPH), nitrite (NO) scavenging and superoxide dismutase (SOD)-like activity. The next, we investigated the possible cell protective effects of the persimmon extract treatment against ultraviolet B (UVB)-induced injury in HaCaT keratinocytes. The contents of total polyphenol and flavonoid in leaf extract of Kojongsi persimmon were increased in time-dependent manner. In Jun, DPPH and NO radical scavenging and SOD-like activities in the leaf extract of Kojongsi persimmon was increased to the highest. However, the antioxidant activities in persimmon varieties were not any difference. The cell cytotoxicity by UVB irradation in HaCaT keratinocytes was significantly increased with the compared to the control group. However, the treatment of leaf extract of Kojongsi persimmon in HaCaT keratinocytes was shown to protective effect against UVB-induced cell cytotoxicity. These results suggest that the leaf extract of Kojongsi persimmon has potent antioxidant activity, and protective effect against UVB-induced keratinocyte injury. Thus, these properties may be contributed in the care of acute and chronic diseases.

Oxidative stress has been implicated in cutaneous damage in various inflammatory skin diseases, including atopic dermatitis. The present study was undertaken to investigate the antioxidative and anti-inflammatory activities of the extract of Duchesnea chrysantha (DCE). DEC was prepared by extracting with 80% ethanol. Total flavonoids and polyphenols were measured by a colorimetric assay. The free radical scavenging activity of the extract was analyzed by the DPPH (1,1-diphenyl-2-picryl hydrazyl), ABTS (2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) and Griess reagent assay. An oxidative product of nitric oxide (NO), was measured in the culture medium by the Griess reaction. The level of prostaglandin $E_2$ ($PGE_2$) was measured by enzyme-linked immunosorbent assay. The expressions of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were measured by Western blot analysis. Total flavonoid and polyphenol contents of DCE were included $24.73{\pm}0.45$ and $178.77{\pm}2.65$, respectively. DCE significantly increased electron donating ability (DPPH), nitrite scavenging (NO) and ABTS reducing activity in dose dependant. We investigated the anti-inflammatory effects of DCE on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. DCE significantly suppressed NO and prdstaglandin $E_2$ ($PGE_2$) in dose dependant. Furthermore, the levels of iNOS and COX-2 protein expressions were markedly suppressed by the treatment with DCE in a dose dependent manner. These results suggest that DEC may has value as natural product with its high quality functional components, antioxidative and anti-inflammatory activities.

The purpose of this study is to identify students' alternative frameworks about tide concept, to investigate some characters of them and students' understanding types with increasing grade in secondary school earth science course. The objective questionnaire method was used, and the subjects of this study are 528 students selected randomly in secondary school. The results are as follow. 1) Thirteen alternative frameworks about tide concept, related to the phase change of the moon and the motion of the earth are identified. 2) The alternative frameworks needed mechanical and causal reasoning have the trend reinforced or sophisticated with increasing the grade. And alternative frameworks needed phenomenal and mechanical, phenomenal and causal reasoning are changed little but ones needed phenomenal, variative and basic reasoning change scientifically. The rates of the alternative frameworks needed definitional, empirical, phenomenal reasoning decrease at the learning grade of that concept but increase after that grade. 3) Middle school students have the definitional, phenomenal, empirical and qualitative understanding types but high school students have the causal, analytic, quantitative and mechanical ones on tide concept.

In this study, the contents of elementary school science textbooks related to 'heat and temperature' are analyzed and alternative conceptions ofi"heat and temperature" among students enrolled in grades 4, 5 and 6 are investigated. 259 students were selected from a elementary school located in urban area. The relationships between students' alternative conceptions and the content of elementary science textbooks are also examined. Students' conceptions are analyzed from their answers to a paper-and-pencil test. The typical alternative conception of "heat and temperature" held by students was follows. They think that "heat" is a material and "temperature" is value of heat amount. They can't distinguish between "heat" and "temperature". Their explanation of "heat and temperature" is focused on hot or cool sensation and other observable characteristics of a material. A textbook analysis indicated that contents on "heat and temperature" were organized without the viewpoint of particle motion theory. This may be one of the causes of students' alternative conceptions.

The purpose of this research is to find out if it is possible to apply the Waldorf School's mathematics education method to Korean alternative schools which are run under the national curriculum. To achieve this, the researcher conducted class on geometry for three weeks with ten 7th graders(four girls and six boys) from Apple Tree Waldorf alternative school in Busan, which has adopted Valdorf education courses. For the first two weeks, the class was about 'fundamental geometrical construction', and then it was evaluated. On the third week, the lesson was on plane figures, followed by a test with 9 plane figure questions that are based on general middle school mathematics curriculum. The result shows that most of the students understood 'fundamental geometrical construction'. When it comes to the test on 'plane figures', seven students got 8 out of 9 right, two students got 6 out of 9 right, and one of them had difficulty solving the questions. According to the results of this research, it is thought that there will be no problem for students to understand mathematical concept even if the Waldorf School's mathematics education method is applied to Korean alternative schools. Also, the Waldorf School's mathematics education method is considered to be a good teaching model for the Korean mathematics curriculum which places emphasis on 'mathematical creativity' in regard to the curriculum and contents.
