In elementary school mathematics, the addition and subtraction of fractions are difficult for students to understand but very important concepts. This study aims to examine the teaching methods and visual aids utilized in the context of common denominator fraction addition and subtraction. The analysis focuses on evaluating the lesson flow and the utilization of visual representations in one national textbook and ten certified textbooks aligned with the current 2015 revised curriculum. The results show that each textbook is composed of chapter sequences and topics that reflect the curriculum faithfully, with each textbook considering its own order and content. Additionally, each textbook uses a different variety and number of visual representations, presumably intended to aid in learning the operations of fractions through the consistency or diversity of the visual representations. Identifying the characteristics of each textbook can lead to more effective instruction in fraction operations.

"Color" education aimed at cultivating creativeness and expressive techniques in the education of visual art, in the college of art and design, should be balanced with "form" education; nevertheless, the present situation at Korean universities is such that the overall environments of "color" education are far too inferior to those of "form" education.The problem is, among other things, that the curriculum of visual art education is centered around formal education; in addition, color education courses consist mostly of theoretical issues, not experimental, first-hand-experience-oriented activities that are best suited for the characteristics of the language of color as a visual language, thereby making it difficult to expect the efficiency of education.Particularly, it is a serious problem that the courses dealing with color are not offered in a step by step fashion, from the most elementary, to the intermediate, working up to the most advanced level. Another problem is that those people involved in color education seldom have an expertise in their area; furthermore, the educational environment, educational tools, and the content of the texbooks are far from being ideal.Moreover, it is a grim reality that most color theory courses that have been offered end up being a lecture of "general, basic" color theories, ignoring the students' diverse specialization areas.As a way of normalizing color education, rationalizing the curriculum and initiating the professorship exclusively teaching color education have to be introduced, so that we can increase the depth of color education and individualize the contents of color education according to the students' needs. It is believed that the introduction of the "color-education-only" professorship will greatly facilitate our effort to devise an efficient educational method, to determine the scope of individualized color education, and to improve the ovarial educational environment (such as facilities, instruments, and teaching materials) necessary for an in-depth education.ments, and teaching materials) necessary for an in-depth education.

Focusing on native plants that have high possibility of being introduced as rooftop material, this study was conducted to investigate extensive and easy-to-manage rooftop garden and to raise the utilization of native plants by verifying their growing response to artificial substrate soil depth and irrigation period. The study was conducted from March to September in 2002. Plants tested included Chrysanthemum zawadskii, Sedium middendorffianum, Thymus quinquecostatus, Allium senescens, and Dianthus superbus. Regarding soil depth, it was 5 cm and 10 cm. Irrigation period was non-irrigation, 1-week, 2-weeks, and 3- weeks, Its result is as follows; 1. In case of Sedum middendorffianum Maxim, mortality rate was 0% regardless of soil depth and irrigation period making it very suitable material for rooftop garden. 2. In case of Allium senescens L., mortality rate was 0% regardless of soil depth and irrigation period making it very suitable material for rooftop garden. Therefore, Provided that fertilizing is managed well, it is a plant that can be highly utilized.3. In case of Chrysanthemum zawadskii Herb. Subsp. (Nakai) Y. Lee Stat., the growth of top was lower in 10cm than in 5cm and it grew well in 10cm. When utilizing for rooftop garden, it would be desirable to keep minimum viable soil depth at over 10cm. If there is enough rainfall, soil and soil depth seem to have greater effect on growth than irrigation period does. 4. In case of Diauthus superbus L. var. longicalycinus (Maxim) Williams, rooting rate and growth were better in 10cm than in 5cm. Therefore, it is desirable to keep minimum soil depth at over 10cm. 5. In case of Thymus quinquecostatus Celak, the growth of top and flowering were better in 10cm than in 5cm. Therefore, it seems desirable to have minimum viable soil depth to be over 10cm. In conclusion, the most suitable species for rooftop garden are Sedium middendorffianum and Allium senescens in this experiment. However, Chrysanthemum zwadskii, Thymus quinquecostatus, and Dianthus chinensis also can be utilized greatly when irrigation is managed regularly in artificial mixed soil over 10cm.

The purpose of this study was two-fold. Firstly, it investigated the current state of the 34 specific policies of school safety-accident prevention that were implemented at K-12 public schools in accordance with the $1^{st}$ School Safety-Accident Prevention Plan established in December 2015. Secondly, it prioritized the policies based on the outcomes from the investigation to make policy recommendations for future improvement. For this purpose, we surveyed 614 school teachers and staff from 24 school-safety research schools across the nation on their perception of the current policies for preventing school safety accidents. Specifically, they were asked about the degree of realization and the necessity of expansion of the policies. Based on the survey results, the Borich index as a needs measure was computed for each policy and a list of policies prioritized in descending order of the index was presented. The results of the study showed that school teachers and staff's perception of the improvement of school safety since the policies took effect was highly positive in general. It was also shown that the policies perceived as best-implemented were, in descending order, "first-aid education for teachers and staff", "safety management of school meals", "prevention activity of student traffic safety-accident", and so on. The majority of survey respondents said that the policies were being implemented well and that they should be expanded and enhanced. As a result of the Borich's needs analysis, it was found that "more collegial collaboration between the Office of Education and other relevant organizations in the community for school safety", "prevention education activity for water safety", and so forth should be more actively implemented.

The research in this paper, for the effective implementation of CBD PoW PA(Program of Work on Protected Areas of Convention on Biological Diversity) that was adopted by CBD COP7(Conference of the Parties) in 2004, shows the objectives and activities of 9 each subject in PoW PA regarding domestic status and cases of national park management. Before anything else, according to the result of the review on the status of protected areas in Korea, there are 1,119 protected areas which are classified into 14 types and the total area is about $15,621km^2$. After a thorough review on 9 each subject about the implementation of CBD PoW PA, we found out that some parts such as management planning, prevention and alleviation of threats, and establishment of PAs system, are improved while financial support, improved social benefit, and MEE(Management Effectiveness Evaluation} fields are need to be improved. Especially regarding time-bound, ecological gap analysis on national level and MEE are need to be improved immediately. This paper could help us to understand the current status of PAs management system in Korea and to prepare national reports of CBD and implementation report of PoW PA. Based on research and results of this paper, we need to find the fields that have gaps in order to meet the requirements of the CBD PoW PA and the implementation tools that are suitable for managing Korea's protected areas. To effectively implement the various activities which require a systematic approach on the national level, the establishment of the networks among relevant organizations for protected areas are vital. To effectively reach the ultimate goal of CBD PoW PA, reducing the rate of biodiversity loss, it is essential that lots of plans established by authorities must be carried out in a constant manner to achieve goals of CBD PoW PA.

The purpose of the study is to identify and understand problems existing in the middle school home economics practice rooms in Jeju Special Self-Governing Province. The findings are based on the examination and the analysis of the indoor environment and the condition of the facilities and equipment. Study method employs on-site research and a survey. The on-site research was conducted about temperature, humidity, intensity of illumination, and status of teaching instrument in 10 out of 41 middle schools in Jeju Special Self-Governing Province from August 16 to September 30, 2006. Meanwhile, the survey was implemented by mail for 95 teachers in charge of manual training and home economics education in 41 middle schools in Jeju from November 1 to 23, 2005. 64 questionnaires out of total 95 were collected, including those collected during the period of on-site research. Finally, 61 questionnaires which were effective among the answered ones were used for analysis. Collected materials were analyzed with the SPSS Win.12.0 program for frequency, percentile analysis. In conclusion, the study determines that the condition of the home economics practice rooms of the middle school in JSSGP in terms of temperature, humidity, lighting and ventilation is very inadequate. The structure of the practice room represents an inefficient work flow pattern. Further, the facilities and equipment are in a very poor condition because the facilities are old and the retention rate of teaching tools is low. Therefore, to address these problems, the study suggests that improvements on the facilities and equipment should be made and teaching tools should be replenished in accordance with the industry standard.

The cultural contents industries have moved closer to the centre of the economic action in many countries and across much of the world. For this reason, the concern with the development of glocal cultural contents has also been growing. According to Goldman Sock's BRICs report, Indian economy will be the engine of global economy with China. In addition, India will be a new blue chip country for large consumer market of cultual contents. The most important point for the development of glocal cultural contents is a systematic and in-depth analysis of other culture. India is a complex and multicultural country compared with Korea which is a nation-state. Therefore, this paper is intended as an understanding about India appropriately and suggestion for a strategy to enter cultural industry in India. As the purpose of this paper is concerned, we will take a close look at 9 Indian culture codes which can be classified into three main groups: 1) political, social and cultural codes 2) economic codes 3) cultural contents codes. Firstly, political, social and cultural codes are i) consistent democracy and saving common people, ii) authoritarianism which appears an innate respect for authority of India, iii) Collective-individualism which represents collectivist and individualistic tendency, iv) life-religion, v) carpe diem. Secondly, economic culture codes are vi) 1.2billion Indian people's God which represents money and vii) practical purchase which stands for a reasonable choice of buying products. Lastly, viii) Masala movie and ix) happy ending that is the most popular theme of Masala movies are explained in the context of cultural content codes. In conclusion, 3 interesting cases , , will be examined in detail. From what has been discussed above, we suggest oversea expansion strategy based on these case studies. Eventually, what is important is to understand what Indian society is, how Indian society works and what contents Indian prefers.

This study aims to establish the lifelong education for the disabled by exploring the academic nature and identity of lifelong education for the disabled from the perspective of convergence, and to guard against a convergence academic system at the level of imitation based on the meaning and function of the established lifelong education for the disabled. The research method consisted of a procedure in parallel with expert meetings based on literature analysis. The content of this study primarily explored the universality and specificity of lifelong education for persons with disabilities in the dimension that it should have an academic essence and identity as a category in which lifelong education for persons with disabilities is fused with several adjacent fields such as special education, centering on the perspective tailored to disability. In addition, the result of exploring the structure system in which the meaning through the universality and specificity of lifelong education for the disabled can be combined not only at the academic level based on theory but also at the functional level based on practice is also presented as the content of the study. As a result of the study, it was analyzed that lifelong education for the disabled can build universality and specificity in the dimension of convergent inquiry, and can establish a support system at a comprehensive level of practice according to the fidelity of the above.
