TIn this paper, we propose a model automatically scoring a student's answer for a descriptive problem by using a voting method. Considering the model construction cost, the proposed model does not separately construct the automatic scoring model per problem type. In order to utilize features useful for automatically scoring the descriptive answers, the proposed model extracts feature values from the results, generated by comparing the student's answer with the answer sheet. For the purpose of improving the precision of the scoring result, the proposed model collects the scoring results classified by a few machine learning based classifiers, and unanimously selects the scoring result as the final result. Experimental results show that the single machine learning based classifier C4.5 takes 83.00% on precision while the proposed model improve the precision up to 90.57% by using three machine learning based classifiers C4.5, ME, and SVM.

Student records are essential for the functional, social, and personal aspects of the university. However, it is difficult to systematically manage such records because of the vast amount produced by several agents, the decentralization of the university's records management system, and various types and forms produced. Despite acknowledging the importance of student records, Myongji University implements its records management system at a sluggish pace. This study defined students' records except for the administrative records of the university as "student-related records" and categorized them into education records, student creation and research records, and student activity records. After examining the best practices in Korea and abroad, we reviewed the current status of Myongji University's student records management system and proposed appropriate and comprehensive management plans accordingly.

This study aims at deriving the implications for adaptation policy and research target regarding climate change risk assessment in ecosystem sector in Korea. The common ground of exemplary cases of "world leaders" in terms of adaptation policies and researches was that they emphasize nationwide study on climate change on biodiversity and ecosystem in target of establishing scientific evidence-bases and reducing uncertainty for their national adaptation policies and plans. In light of this trend, Korean government should settle down more successful adaptation structure by leading adaptation system in further national policy-settings to observe UNFCCC and CBD integratedly and effectively, considering the economic value of adaptation in policy, and strengthening scientific research programs and technology developments. Moreover, risks assessment based on diagnoses and analysis on the risk factors (hazard, exposure, and vulnerability) for climate change in nationwide habitats and species and consolidations with subsequent adaptation strategies could make adaptations in ecosystem sector more effective and successful.

As greenhouse gas (hereinafter GHGs) emissions have been increasing, the world's climate is also rapidly changed. $CO_2$ is the most important artificial GHGs and the annual emissions amount was increased approximately 80% between 1970 and 2004. After suggesting Kyoto Protocol, EU is the second largest emissions embodiment in the world, set the emissions trading scheme (hereinafter EU-ETS) and is trying to reduce $CO_2$ emissions aggressively. This study focuses on the EU-ETS and EU-ETS market to examine their emissions reduction policy and review the result of their efforts. EU-ETS which is composed of 2-step phases had already completed the first phase and is running on the second phase in 2008. Up to now EU-ETS has been proceeding successfully and the amount of $CO_2$ emissions has been decreased. To prepare for their coming events, countries excluded from Kyoto Protocol fulfillment need to have some implication from EU and have to make up their own plans.

How did Japanese who surrender to Joseon reflect in old proses / Seo, Shin-hye This paper is focus on Japanese who surrender to Joseon. I researched how were these people to live through old novel, old tale and old biography. And I researched how these works reflected these people. Usually Japanese who surrender to Joseon were butchers. They were loyal to Joseon and their higher officer to a fare-thee-well. In old proses, writters compared these surrender with Joseon's general. People expect the general loyalty, but he didn't. Because of surrender's loyalty, Joseon's general was seen as an abject coward. This form came out in common in the biography of Gim Yeongcheol, the biography of Gang Hongrip and the biography of Gim Chungseon. But this fact was biased. All of Japanese surrender was not loyal, and they liked fighting in the battle. The singularity of the biography of the butcher who is Buddhist monk attracted our attention. In this work, we can see the surrender's mental conflict. We can realized the people is equal with Joseon's people.

In this study, the characteristics of the experiences and perceptions of vulnerable adolescents on the school environment were explored and categorized, and of which the meanings were confirmed. For this purpose, Q methodology was used, and 94 Q samples were extracted by analyzing pre-interviews, literature analysis, and media search contents to form a Q population. Q classification was performed on the subjects. The schools belonging to the sample P are 7 high schools in Seoul and 4 high schools in Gyeonggi-do. As a result of analyzing the data collected in Q sorting using QUANL-PC program, a Q analysis program, it was classified into 4 types. Type 1 is 'a conformal and moeling type', and Type 2 is 'negative and defiant type', Type 3 is 'passive and helpless type' and Type 4 is 'progressive and struggling type'. Through this study, it is expected that this study will be able to understand the experiences and perceptions of the school environment of underprivileged adolescents, and to obtain the necessary clues for realistic support strategies for them.

In this paper, we designed and implemented a graph assessment module that can evaluate graphs in an programming assessment system based on text and numbers. The assessment method of the graph assessment module is self-evaluation that outputs two graphs generated by codes submitted by learners and by answers, automatic-evaluation that converts each graph image into an array, and gives feedback if it is wrong. The data used to generate the graph can be inputted directly or used from external data, and the method of generatng graph that can be evaluated is MATLAB style in matplotlib, and the graph shape that can be evaluated is presented in mathematics and curriculum. Through expert review, it was confirmed that the content elements of the assessment module, the possibility of learning, and the validity of the learner's needs were met. The graph assessment module developed in this study has expanded the evaluation area of the programming automatic asssessment system and is expected to help students learn data visualization.
