  • In this paper, we reviewed the assessment criteria and conservation value used to evaluate vegetation. The Degree of Green Naturality (DGN) and the Grade of Vegetation Conservation (GVC) are both sets of criteria that estimate the degree of human disturbance or natural value of vegetation. The criteria are extensively used in decision-making about the natural environment conservation and environment impact assessment. Sometimes, social issues can rise because the criteria are not clear. This study aims to evaluate the criteria based on the many aspects of the related literatures and suggest reasonable revised criteria. In addition, criteria for representing the relative value of valuable vegetation conservation are suggested. The DGN and GVC are essentially same; both have 11 degrees and 5 grades. While the DGN is subdivided into levels of anthropogenic disturbances, the GVC indicates the priority for conserving valuable vegetation. Therefore, the DGN is very useful for assessing land development projects, etc., while the GVC is needed to delineate the Ecological Assessment Map(EAM). In conclusion, it is desirable that both criteria should be used together appropriately.

  • Recently, domestically and abroad, programming education has become more important and this increase has been recognized. And it needs a certain criteria for a selection of programming tools because there are various educational programming tools coming out. Thus, we tried to develop a criteria on the selection of educational programming language for a novice programmer and K12 students and verify its validity. So we established 4 areas and 28 items for selection criteria on educational programming language. Additionally, we carried out delphi survey and analyze for validity verification on selection criteria established. As result of carrying out of these processes, we developed 4 areas of selection criteria. Finally we have chosen 19 selection criteria and excluded 9 criteria items which are not sufficient with validity criteria through delphi survey.

  • This study is with the subjects of 7 primary schools in Daejon City which opened after 2004 when the Ministry of Education & Human Resources Development released the "Study of Developing the Manual for Safety and Plan of school facilities". This is to study the measures of improving or enhancing the safety criteria on the school facilities from the viewpoint of actual planning as well as of architectural planning through investigating and analysing the cause, the status and the type of negligent accidents by school which are occurring both directly and indirectly. Though the analysis of the examined contents shows there is no facility in primary schools not satisfying 'the criteria on safety maintenance of school facilities', the criteria is so comprehensive and general that its content is just itemized and the current criteria of facilities are not fit for the present situation because of the physical condition of the students in elementary, middle and high schools and the changing curriculum.

  • In order to develop an appropriate set of criteria applicable for environmental impact assessment (EIA) of natural forest 8 items are proposed. The criteria are vegetation distribution area (DA), distribution pattern (DP), size (S), diameter of breast height of tree (DBH), humus (H), sustainment (ST), successional stage (SS) and impact of adjacent ecosystem (IAE), Each criterion has an interval which minimum 1 score to maximum 5 score Forest Evaluation Index (FEI) was obtained as the sum of 8 criteria value. Above 70% is considered to be absolutely conservative and from 50% to 70% range of total score is to be considered conservative. In the case of the Sancho˘ng Pumping-up Power Plant of Mt. Chiri, 8 criteria were applied base on actual vegetation map. Pinus densiflora community got 73%(29 scores) and Quercus variabilis - Q. serrata community got 60%(24 scores). This may be said that this local vegetation has high ecological potentiality. These criteria cannot always be absolutely evaluation tool. So it is expected to take the more time to be developed further, and holistically added by the other field such as fauna, geological feature etc.

  • Recently, there are effects such as commercial investment and introducing new technology by introducing a BTL project. As a result, School's conditions are getting better and Numbers of certified schools are increasing, because the Green Building Certification Criteria was created in 2002 and expanded to schools in March, 2005. But the certificated schools just get the minimum score for certificate level 'good' about 65 points and there is no certificated school level 'very good'. The users of school stay in long time in the facility cause of the unique function of school. It means Indoor Environment Quality Criterion of the school is very important than any other criteria. Therefore, this study aims to analyze the indoor environment factor for the plan of the certificated school by green building rating systems. And this study also wants make the basement of a substantial technical application and development of the criteria in the plan for sustainable green school.

  • This paper investigates the evaluation criteria in order to manage healing environment of long-term care elderly hospital. Elderly hospital evaluation tool developed by Korean Government is used to assess elderly hospital facilities to check the hospital facility and maintain its quality. However, the evaluation indicators and questions mainly focusing on safety indicators. Some questions are too vague for precise evaluation. In this paper, we discuss the advantages and disadvantages of the present evaluation criteria to establish new assessment tool for precise evaluation. The literature research was conducted tp set up the new evaluation criteria. From this research, we developed an elderly focusing on healing environment checklist for elderly care hospital which contains 7 factors as the primary hierarchy structure (Safety, Accessibility, Amenity, Sensibility, Friendly to nature, Territory, Interaction) and 23 factors as the secondary hierarchy structure. This evaluation criteria will help healthcare facility designers and healthcare organizations to build the healthcare facilities.

  • Pathfinding for pedestrians provided by various navigation programs is based on a shortest path search algorithm. There is no big difference in their guide results, which makes the path quality more important. Multiple criteria should be included in the search cost to calculate the path quality, which is called a multi-criteria pathfinding. In this paper we propose a user adaptive pathfinding algorithm in which the cost function for a multi-criteria pathfinding is defined as a weighted sum of multiple criteria and the weights are learned automatically by Perceptron learning. Weight learning is implemented in two ways: short-term weight learning that reflects weight changes in real time as the user moves and long-term weight learning that updates the weights by the average value of the entire path after completing the movement. We use the weight update method with momentum for long-term weight learning, so that learning speed is improved and the learned weight can be stabilized. The proposed method is implemented as an app and is applied to various movement situations. The results show that customized pathfinding based on user preference can be obtained.

  • Even though the final source selection of foreign weapon system purchase project in defense area is the most important phase, the standard evaluation index has not been developed. This paper provides an appropriate evaluation index using DEMATEL and ANP methods. First, the all possible evaluation criteria applied to the relevant previous literatures in domestic and overseas researches are derived and classified into groups. Second, DEMATEL method is used to determine the network structure representing the relations of cause and effect between groups and their sub-criteria. If isolated factors, not connected with other factors, are existed in the network structure, all factors except for the isolated ones are grouped as one large factor so that the independency between those ones is maintained. The weights of criteria are determined using AHP method if the criteria are independent relation and ANP method if the criteria are networked. The weights of higher and lower level criteria are then integrated and distributed as a point with respect to the decision making purpose. The developed evaluation index can be used as a standard one in various foreign weapon system purchase projects in defense area.

  • In order to improve software development productivity and quality, reuse approaches and supporting library systems have been proposed. Library systems have applied various methods to classify, store, retrieve, and comprehend reusable components effectively. As the number of library systems grows, it is difficult to categorize, compare and analyze existing reuse libraries. In this paper, we present classification criteria for reuse library systems. A set of criteria is defined by integrating facet-based and attribute-based classification methods which encode the properties of a reusable component. In order to show the usefulness of the proposed classification criteria, representative library systems based on application domains, as well as component classification methods ore selected and reviewed. We then classify these library systems according to the proposed criteria.

  • The purpose of this study is to compare the preferences of the school mathematical terms of South Korea and those of North Korea by administering a survey for learners, inservice teachers, and pre-service teachers, to establish the criteria of desirable school mathematical terms, and to evaluate the school mathematical terms of South Korea and those of North Korea based on the criteria. According to the result of the survey, the preferred mathematical terms are different from one group to the other, yet the mathematical terms of South Korea are more preferred. In general, terms written in pure Korean and concise terms which are easily understandable are favored. To discuss about the criteria of desirable school mathematical terms, four perspectives were set up, 1) the semantic perspective and the regulatory perspective, 2) terms written in pure Korean and Chinese letters, 3) terms from everyday language and technical terms, and 4) the consistency. Six criteria were followed from the aforementioned four perspectives. Finally, various school mathematical terms of South and North Korea were reviewed in the angles of the four perspectives and the six criteria.
