This study was designed to explore how learners' participation develop if provided with opportunities for various scientific practices and experiences in writing science magazine articles as an extra-curricular club activity and what factors facilitate these participation development. Data from participant observations, in-depth interviews with students, and documents were used to extract the common characteristics of the practices. The learners' development was categorized into 3 stages in terms of participation in the community of practice: peripheral participation, transitional participation, and full participation. As participation develops, situational interest developed to individual interests and value attachment. Students sought to get ideas from every day life, and finally, in the stage of full participation, advances in writing showed the characteristics of knowledge transformation. Best of all, the participants enjoyed and valued their participation showing identities as journalists. The nature of science magazine article, external scaffolding, and internalization through enjoyment and value attachment appeared to be decisive factors that facilitate the development of participation. Student's enculturation of writing for learning offers a possibility that continue to do so, even after they have left formal schooling and make a basis for lifelong learning.

Libraries, not only research libraries but also public libraries, have been fundamentally affected by the immense spread of the Internet and the World Wide Web. Many public libraries have their Web pages, through which they are providing their new and conventional services. There are also web sites which provide library-like services. This paper shows an experimental project named Internet Public Library Asia, which provides information in multiple languages of information resources published in Chinese, Japanese and Korean languages. This paper firstly overviews how traditional public libraries have been affected by the Internet. Then, it describes a few aspects from the viewpoint of crucial library function on the Internet and also from the viewpoint of Asian resources and users. This paper secondly proposes a model to serve information about valuable resources published in multiple Asian languages, and then shows the metadata schema and a few software tools developed for IPL-Asia The name of IPL is borrowed from Internet Public Library based at University of Michigan, since it is, in part, a collaborative activity with the IPL in Michigan. The metadata schema is defined based both on Dublin Core and IEEE LOM and adapted for parallel description in the four languages, i. e. , Chinese, Japanese, Korean and English. The software tools provide functions to support collaboration among people engaged in development of metadata database and metadata editing. These tools have been developed based on the XML technologies.

Many researches related to STEAM education have been actively conducted for developing elementary and secondary school students' comprehensive and logical thinking ability in relation to creativity education in Korea. Each sub factor of STEAM education requires creative thinking with the ability to be merged together to solve problems as integrated or combined forms in the fields of Science, Technology, Engineering, Arts, and Mathematics. Also, these STEAM activities and experiences should be carried out at various places outside the classroom in school. Although various educational programs to enhance mathematical creativity have been emphasized for elementary and secondary school students, recent tendency to focus on classroom learning in the school makes it difficult to develop creative thinking ability of students. This research is mainly based on the result of the project "Development and Administration of STEAM Outreach Program in 2016" supported by KOFAC(Korea Foundation for the Achievement of Science & Creativity). The purpose of this research is to develop a STEAM outreach program including students' activity books, teachers' manuals and administration manual that can maximize STEAM-related interest of students, and to provide a chance for elementary and secondary school students to experience creative thinking based on sub factors of STEAM. The STEAM competency total score and the perception of convergence education were significantly increased for all students participating this program, but some sub factors showed different result by school levels. The STEAM outreach program developed by this study is designed to emphasize STEAM education especially 'based on' mathematics in order to provide students with the opportunity to experience more interest in the field of mathematics and will be able to provide an interesting creative STEAM outreach program that utilizes a variety of activities which, we expect, would help students to consider their career in the future.

Recently, as service design was introduced to improve the quality of public service, there have been many attempts to improve various public service. In the process, various stakeholders including general citizens are participating in the design improvement activity through a method of design service but the parties are facing a difficulty in the progress because of a limitation of time and budget and a lack of professionalism among the member while the parties are planning the process and activities based on the professional service design method. Persona method that is usually used in the process of service design is encountering a limitation as well. Also, there are continuous attempts to understand the limitation of persona and apply an alternative research method among service and UX designers. For this reason, this thesis is to recognize the limitation in deduction method of traditional persona and suggests a fast and economical production method of Rapid Persona speaking for the goal of users and overcoming the limitation. Furthermore, by applying the suggested method of making Rapid Persona to an actual public service design project of National Statistical Office, the test through an empirical study was conducted. This was conducted with the purpose of progressing a discussion in the respect of actual application beyond a banal discussion. Through the research method suggested in this study, it is expected to overcome the limitation of time and a lack of professionalism and, based on these, can be used in the process of various service design and UX design as establishing persona in a fast and easy way.

The objective of this study was to determine whether Codonopsis lanceolata or Platycodon grandiflorum ethyl acetate fraction (CLEA or PGEA) protect cells against sodium nitroprusside (SNP)-induced oxidative stress via the expression of various antioxidant systems. The HepG2 cells exposed for 24 hr to 0.5 mM SNP showed a reduction in the cell viability by an MTT assay. Pretreatment with CLEA and PGEA resulted in an inhibition of SNP-induced cell death. In addition, the effects of CLEA and PGEA on the expression of antioxidant systems via RT-PCR analyses was assessed. The levels of catalase (CAT), glucose-6-phosphate dehydrogenase (G6PD) and metallothionein (MT)-1A mRNA were increased after 24 hr of CLEA exposure. The levels of Mn superoxide dismutase CAT, G6PD, MT-1A, and MT-2A mRNA were increased after PGEA treatment. In conclusion, CLEA and PGEA exert indirect antioxidant effects, perhaps via the induction of a variety of antioxidant systems which, may protect cells against oxidative stress.

In software R&D artifacts including documents and program code are produced. There are two kinds of software R&D artifacts: Research artifacts and development artifacts. Research artifacts include software R&D planning document, annual report, final report, research note and so on. Software development artifacts include software requirements, software design description, testing plan, test report, and program code. It is important to verify the documents and to test code to check the direction of the R&D. Moreover, we should check relationships as such completeness and consistency between research and development artifacts. The verification and testing help project manager and researchers understand what they do during software projects. Therefore, in this study, we present a process to verify documents and program in software R & D. In the process we check documents produced in software R&D and test program code. We describe the process by using Essence elements including alpha, activity, and competency. We present a case study to show the effectiveness of the process.

This research was conducted to analyse how a community building around empowerment changes the resident's cognition depending on level of their participation. 'Livable hope community building project' in Gonju-Shi, Chungcheongnam-Do was chosen as an example case. As a result of analyzing influence of residents' participation on their cognition changes, the residents with higher level of participation had bigger changes in cognition in terms of individual and relational aspects. In detail, the residents with one time of participation in livable hope community building activity showed a change in cognition in a way that they realized the reality of the rural area and felt the necessity of community building to overcome this. The residents with more than 3 times of participation had cognitional change on current status of village where they are living in. Lastly, the greatest cognitional changes in all perspectives occurred among the residents with more than 5 times of participation. They had a firm cognition that the participation and cooperation of the residents are important to make community building successful. Conclusively, community building around empowerment influences recovery of rural community as it changes cognition of residents and acts as a mediator for resident unity. Therefore, it is expected will bring new changes to rural area, help recover rural community, and affect improvement of rural competitiveness.

This study attempted to find an efficient method for the preparation of high-purity galactooligosaccharides (HP-GOS) using ${\beta}$-galactosidase and yeast fermentation. GOS prepared using Lactozym 3000L showed the greatest enhancement in total GOS of the six ${\beta}$-galatosidases tested. GOS alone achieved 51% conversion of initial lactose. GOS production was enhanced by fermentation with commercial yeast (Saccharomyces cerevisiae); its concentration reached 71% after 36h fermentation with 8% yeast. Component sugar analysis with HPLC indicated that HP-GOS fermented with S. cerevisiae showed significantly increased levels of 4'/6'-galactosyllactose and total GOS as well as a significantly decreased glucose level. HP-GOS facilitated the growth of Lactobacillus sp. (L. acidophilus and L. casei) and Bifidobacterium sp. (B. longum and B. bifidum). In sum, high-purity GOS has been successfully produced through both an enzymatic process and yeast fermentation. GOS encourages the growth of bacteria such as Lactobacillus and Bifidobacterium that may be beneficial to human gastrointestinal health.

Although it is uncertain that the cause of changed pattern of the natural disaster related to water (i.e. flood and drought) is due to excessive carbon dioxide yielded from economic activity or the increased number of sunspots, it is apparent that there have been unusual climate change that directly affects the water resource management. Due to such a frequent unusual weather activities, there have been increased natural disaster and the most direct and major reason is considered as climate change. As we see, the climate change necessarily causes social costs. Especially, the effects on the water resource due to flood and drought take the considerable part of such costs. Therefore, this study is basic work to develop a new economic analysis technique to be used in pursuing appropriate adaptation project in field of the amount of cost damage through analysis of the effects of the climate change on the water resource. The models appeared in many reports for cost assessment of climate change were various (e.g., PAGE, DICE, AIM, IMAGE, MERGE, and etc.) and this report summarizes general characteristics of each model. To assess the effects of climate change of the water management, we defined the field of the water management on climate change. The results help post-study in field of the climate change's social-economic effect assessment, can be employed for the prioritizing process of the national fund's investment.

The Small and Medium Business Administration specified 123 construction materials mandatory to purchase directly and forced the public owners to provide the contractors with materials as required by related law. This study extensively reviewed various characteristics and management factors of the owner-providing materials consumed in the public apartment housing under Direct Buying System(DBS) from the public owner's perspective. Subsequently, the major managed materials were identified, and the proper response plan was developed along the material procurement process. The Procurement Management Load Indices (PMLI) of 43 materials were evaluated according to rating criteria with procurement path, project-specified level, user requirement level, supplier's responsibility, on-site work requirement, additional parts, and inspection standards. The tile and aluminum windows were classified in the group needing high-level procurement efforts to reduce the errors and ensure the efficiency. The accurate quantity estimation method, definite purchase details, management activity definition before and after production, additional quantity for rework, interference coordination were defined as the essential activities for effectively responding to DBS.
