The Environmental problem solving model is an instructional strategy to accomplish the aim of environmental education through investigation of environmental problems and issues of the community. This study is intended to compare the instructional effect of the structured model with the unstructured model of environmental problem solving. The experimental group received the structured instruction and the control group received the unstructured instruction. There did not appear to be any significant difference between the groups in regard to knowledge but in regard to knowledge of environmental issues, the experimental group was more effective than the control group. No significant differences existed between the groups in attitude. In regard to investigating skill and evaluation of environmental issues, the experimental group was significantly more effective than the control group. The experimental group was significantly more effective than the control group in regard to environmental action skills. To foster responsible environmental behavior, environmental education a number of methodologies must be considered and learners must be trained to become problem-solving citizens. It was noted that the structured instruction was more effective than the unstructured instruction in middle school where environmental issues were not taught as an independent subject. We conclude that environmental education must be systematically constructed and taught in a manner which takes into account both its goals and the characteristics of the various learners. We conclude that environmental education must be systematically constructed and taught in a manner which takes into account both its internal goals and the situations within which various types of learners explore environmental issues and solutions.

In this study, the information from environmental impact statements was converted into spatial data because environmental data from development sites are collected during the environmental impact assessment (EIA) process. Spatiotemporal big data were built from environmental spatial data for each environmental medium for 2,235 development sites during 2007-2018, available from public data portals. Comparing air-quality monitoring stations, 33,863 measurement points were constructed, which is approximately 75 times more measurement points than that 452 in Air Korea's real-time measurement network. Here, spatiotemporal big data from 2,677,260 EIAs were constructed. In the future, such data might be used not only for EIAs but also for various spatial plans.

The student dropout prediction is an indispensable for many intelligent systems to measure the educational system and success rate of all university. Therefore, in this paper, we propose an intelligent dropout prediction system that minimizes the situation by adopting the proactive process through an effective model that predicts the students who are at risk of dropout. In this paper, the main data sets for students dropout predictions was used as questionnaires and university information. The questionnaire was constructed based on theoretical and empirical grounds about factor affecting student's performance and causes of dropout. University Information included student grade, interviews, attendance in university life. Through these data sets, the proposed dropout prediction model techniques was classified into the risk group and the normal group using statistical methods and Naive Bays algorithm. And the intelligence dropout prediction system was constructed by applying the proposed dropout prediction model. We expect the proposed study would be used effectively to reduce the students dropout in university.

A projective Schur algebra associated with a partition of finite group G can be constructed explicitly by defining linear transformations of G. We will consider various linear transformations and count the number of equivalent classes in a finite group. Then we construct projective Schur algebra dimension is determined by the number of classes.

We construct an operad which is called the mapping class group operad. Its structure map is induced by the attachings of surfaces. The similar operad was constructed by Tillmann in order prove that ${\Gamma}^+_{\infty}$ is an infinite loop space. Our operad is rather simpler and easier to deal with.

In this paper, a method based on group divisible designs is presented for constructing some partial diallel crosses. We discuss in detail a particular inbred line, i.e., p lines divided into two groups with p$_1$ lines and p$_2$ lines. These designs are obtained by regarding the number of lines as treatments. In specially we study and compare the efficiency factors of the constructed partial diallel crosses with or without repeated blocks.

In this paper, I examined the history of Baizu that the Brief History presented. PRC created Baizu as one the 55 ethnic minority nations, as it "nationalized" all the people living within its territorial boundary. And it constructed the narrative of the "ethnic history" of Baizu, while it constructed the grand narrative of the history of the unified, multinational "zhonghua minzu." There are two major problems in the historical narrative of Baizu, thus constructed. First, the genealogy of the ancestors of Baizu constructed by PRC lacks sufficient historical evidence to prove it. Second, the politically-driven ethnic classification project by PRC produced ethnic minority nation, which does not have their own territory and Baizu was one of them. Because of this, the history of Baizu, who historically lived mixed with other ethnic groups together in Yunnan, cannot help but becoming a part of the larger Yunnan history, rather than constituting a history of an ethnic group. Then, what would be a historically sensible way to write a history of ethnic minorities in Yunnan, who have not transformed themselves into a modern nation? What I would like to suggest is, first, to abandon the construction of the history of Baizu as an ethnic group. I also suggest to distinguish Yunnan from China (zhongguo) as a unit of historical writing, and thus to cut the relationship between the Baizu history and the larger history of the unified, multitethnic "zhonghua minzu." The narrative of the Chinese history (history of Zhongguo), which takes the PRC's current territorial boundary as the unit of historical narrative, lacks historical objectivity. Names for historical communities survive, because they have been used by those who have lived in the communities as well as by other historical communities. Members of a certain historical community occupy distinctive historical space and share common historical experience. And their historical experience is mainly informed by political changes that affected the space that the historical community occupies. If one constructs the history of "Yunnan" as a distinctive historical space and community, which could be distinguished from the historical "China" (zhongguo), one may be able to construct the history of the people of Yunnan in its fullest sense.

게임의 발전에 따라 게임에 등장하는 NPC(Non-Player Character)들의 지능 또한 중요성을 더해 가고 있다. 단순히 이동하고 플레이어를 공격하기만 하는 수준을 넘어서 WPC들 역시 다양한 기술과 전술을 사용하는 것이 최근의 MMORPG 게임의 추세이다. 본 논문에서는 신경망과 유전자 알고리즘을 이용하여 롤플레잉 게임에 사용되는 캐릭터에게 학습 및 적응 능력을 부여하는 방법을 제안한다. 제안된 지능 캐릭터가 얼마나 게임의 규칙과 전술을 잘 학습하고 적응하는지를 살펴보기 위하여 본 논문에서는 간단한 게임 모델을 제작하여 실험하였다. 캐릭터는 탱커(Tanker), 딜러(Dealer), 힐러(Healer)의 3가지 종류가 있으며, 지능 캐릭터 집단은 신경망과 유전 알고리즘으로 학습되고 FSM으로 움직이는 적 캐릭터 집단과의 전투를 통해 학습한다. 실험 결과 지능 캐릭터가 전투를 통해 자신과 적의 능력에 따른 적절한 전투 방식을 스스로 학습하고, 게임 규칙의 변화에 적응하는 것을 볼 수 있었다.

This research aims to establish the size standard of university library's user space, and present the standard and method to calculate total area required in the planning of new building construction and remodeling. Nine university libraries newly constructed or remodeled since 2000 were selected among the libraries of large scale universities with more than 10,000 enrolled students as the target libraries in this research. The target libraries were classified into A group (five cases partially remodeled) and B group (four cases newly constructed or fully remodeled) on the basis of the change of times. A university library can be divided into three spaces (user space, administration space and public space). This research classified the reading room in the user space into bookshelf zone, reading zone, information/office zone and hall/other zone, and analyzed area ratio according to each zone. B group's bookshelf zone decreased 12% more than A group, and B group's reading zone increased 10% more than A group. However, there was no big change in the area ratio of information/office zone and hall/other zone. This can be interpreted that university library changes from book and archive preservation-oriented space to user-oriented space. This research presented a proper reading room area calculation method, based on the capacity of books, by reflecting such a change. Each zone's standard was set up through classification of domestic and international standards, based on which, the calculation method of university library's total floor area required was presented. The reason why there was difference in university library's total floor area required according to domestic standard and international standard was that the number of enrolled students per seat in the reading room was different. The area calculation methods presented in this research can be utilized as useful data upon planning university library construction or remodeling.
