The openness of residential space directly affecting lighting, view, and ventilation leads to the variation of open floor plan type in apartment construction project. This study intends to substantiate the effect to the apartment price by design property of open floor plan based on actual design information of apartment and price. The open floor plan type and associated design property, and actual transaction price of apartment have been considered as variables for analysis by the hedonic price function model and artificial neural networks model. Research findings indicate that the openness affects the price of apartment positively and the three sides open plan is the most preferred with the highest price. This study aims to provide the implication to the developer in planning and design stage of apartment and the purchaser seeking the suitable price by floor plan design.

This is a study on types and current status of school library in japan that are open to public. it aims to increase library access and further improvement of accessible information environment by opening the libraries within schools. In case of Japan, libraries' importance to school education enacted world's first School library act by 1953 and installation rate of school libraries is achieved up to 100%. These libraries opened to its local community is in the process of increasing library usage and now in total of 11.6% of lower, middle, and upper school are already opened to their local community. Considering decreasing usage of facilities in schools, teacher vacant time, expanding libraries, and other various alternatives should be considered together. It will lead to equal access to information environment and lifelong education. The study suggests ways of installing school libraries in appropriate sizes and forms within their local societies. It also propose possible ways to open school libraries to perform their own functions.

The purpose of this study is to figure out gifted elementary science students' improvement in performing open inquiry after peer review. In this study, gifted fifth-grade students performed open inquiry and review of each other as peers after the inquiry. Students' inquiries were evaluated and the influences of the feedback from the peer reviews were analyzed in relation to the inquiry performances. As a result of this study, three key points were discovered: First, the evaluation score increased with frequent feedback or long discussions. On the other hand, with less feedback, the evaluation score didn't rise. Second, there were three types of improvement in inquiry related to peer review: No. 1 was improvement after feedback given by themselves. No. 2 was reflection of feedback given to other groups. As a last type, No. 3 was that the students learned from other groups' presentation without any feedback and improved their inquiry. Third, there were five kinds of giving feedback; (1) feedback understanding the inquiry correctly, (2) insufficiency of peer's inquiry without deep thought. (3) on the usefulness of the inquiry, (4) on the scientific and logic validity through critical thinking, and (5) how to develop the inquiry. In these kinds of feedback, the fourth kind of feedback (4) occurred most frequently but the fifth (5) occurred rarely. It means peer review helps students develop their critical thinking ability and teachers should encourage students to give peers feedback of the fifth kind.

본 연구는 현재와 과거의 하도 지형자료 분석을 통하여 만경강에서 나타나는 폐천(Abandoned channel)을 파악하고, 유형을 폐쇄형, 개방형, 육화형 폐천으로 구분하여 각각의 본류구간과 함께 식물상 및 식생분포 특성을 비교하였다. 만경강의 경우 1918년 하도 형태가 경지정리 및 치수사업에 따른 제방축조 등 인위적인 절단(Engineered cutoff)으로 8개소 이상의 구간에서 하도 선형이 크게 변경됨으로써 폐천이 형성되는 것으로 나타났다. 현재 폐천부지는 육화형태의 농지 이용 및 개방형 또는 폐쇄형의 습지로 유지되는 것으로 조사되었다. 폐천 유형에 따라 나타난 식물상은 폐쇄형 56종류, 개방형 31종류로 조사되었다. 육화형의 본류의 경우 보에 의한 영향으로 달뿌리풀 (Phragmites japonica)과 저수로 검정말(Hydrilla verticillata) 등의 수생식물이 우점하는 정체수역이 나타났다. 개방형 폐천은 갈수기에도 수심이 깊은 수역이 확보되어 본류에 비하여 출현종수가 높았다. 폐쇄형 폐천은 연꽃(Nelumbo nucifera), 애기부들(Typha angustifolia) 등의 다양한 수생식물이 출현하여 본류에 비해 안정된 습지 생태계를 유지하였다. 만경강의 개방형과 폐쇄형 폐천은 수생식물의 증가와 전형적인 습지생태계를 유지하고 있었으며 본류의 정체수역이 관찰되었다. 본래 하천의 연속성을 향상하기 위한 유수생태계의 복원은 하천의 건강성을 향상하기 위한 방안이 될 것이다.

Under the open innovation paradigm, it is needed to establish an appropriate strategic planning tool which can take both internal and external resources and capabilities into account. In response, this paper suggests the open roadmap to systematically and usefully implement open innovation. The open roadmap deals with both inbound and outbound open innovation activities. Moreover, in the inbound and outbound open innovation, six types of the open roadmap are proposed in terms of sources of innovation. The proposed open roadmap is applied to a case of open innovation in the P&G corporation for examining its usefulness and validation. It is expected that the open roadmap provides fruitful information when open innovation is done.

This study conducted an analysis of types of reasoning shown in students' solving a problem and processes of students' reasoning according to type of problem by posing an open-ended problem where students' reasoning activity is expected to be vigorous and a multiple-choice problem with which students are familiar. And it examined teacher's role of promoting the reasoning in solving an open-ended problem. Students showed more various types of reasoning in solving an open-ended problem compared with multiple-choice problem, and showed a process of extending the reasoning as chains of reasoning are performed. Abduction, a type of students' probable reasoning, was active in the open-ended problem, accordingly teacher played a role of encouragement, prompt and guidance. Teachers posed a problem after varying it from previous problem type to open-ended problem in teaching and evaluation, and played a role of helping students' reasoning become more vigorous by proper questioning when students had difficulty reasoning.

Recent studies focus on how open innovation strategies affect innovation in enterprises, but lack research related to the forms of openness. There is also a paradox that an entity should open up for open innovation but also protect its innovation. In this regard, the need for research on innovation protection has expanded. Therefore, this study looked at the effect of the form of openness on product innovation, and explored how the relationship between the form of openness and product innovation depends on the appropriation mechanisms. This study used data from the Korean Innovation Survey(KIS), which was developed and distributed by the OECD. The main findings of this study are summarized as follows. First, the forms of openness has a positive effect on product innovation. Specifically, external search has had a positive impact on exploitative innovation, and collaboration has shown to have a positive impact on exploratory innovation. Second, the appropriation mechanisms has a positive moderating effect on the relationship between the forms of openness and product innovation. Specifically, it was shown that formal appropriation mechanisms had a positive effect on the relationship between external search and product innovation, and that informal appropriation mechanisms had a positive effect on the relationship between collaboration and exploratory innovation. This study is expected to contribute to: First, this study has divided the forms of openness into external search and collaboration, unlike the existing method, and thus identified the type of product innovation and the appropriation mechanisms and forms of openness by identifying the impact on product innovation. Second, depending on the characteristics of the appropriation mechanisms, it was identified that it had the moderating effect on the forms of openness and the relationship of product innovation, so that depending on the type of openness and the type of product innovation, the type of appropriation mechanisms more suitable was identified.

Mathematical Communication ability can be more developed through sharing thoughts with others. Therefore when we instruct students in math, it is very important for teachers to provide them with opportunity to communicate mathematically. So this study provided open-ended problems in small-group collaborative learning. And we analyzed students' mathematical communication focused on the student's level of understanding. Furthermore, to improve students' mathematical communication ability, this study tries to attract the factors that we should consider the exact date for inserting the open-ended problems into a course of math and the student's level of understanding for selecting suitable open-ended problems.
