  • The purpose of this study is to investigate and analysis importance for evaluation indicators in youth centers. The sample of it is 138 youth centers. Method of this analysis of importance for its indicators is AHP(Analytic Hierarchy Process). Evaluation domains in youth center are process evaluation, product evaluation, input evaluation and specialized program in order of importance. Also, it is important to evaluate in needs assessment, recruitment of youth instructor, participation of youth in decision making, connective project with schools, sanitation level of youth center, satisfaction research, efforts of improvement of youth center staff in evaluation indicators. The result of this study is that importance for evaluation indicators suggests developmental directivity in youth center management.

  • This study was conducted to propose a way to increase the accuracy and precision of 𝛽-ray measurement equipment. Statistical processing results of equivalent evaluation data from 2016 to 2021 confirmed that the concentration of micro dust measured by 𝛽-ray measurement equipment was higher than that of micro dust sampler. According to quarterly data, it was confirmed that the data from the third quarter (July to September) showed a different trend from other periods, which is assumed to be due to weather conditions. This study indicates that automatic micro-dust measurement equipment evaluation at air pollution measuring stations during the third quarter should be excluded. The evaluation cycle should be changed from once every two years to quarterly. In addition, when the criterion for determining equivalence evaluation falls within the range of the slope and intercept values of the existing trend line, it is necessary to evaluate the R2 value together and reduce the slope from 0.9-1.1 to 0.9-1.0.

  • The objective of this study is to develop and evaluate simple and multiple regression models for Total Organic Carbon (TOC) concentration estimation in stream flow. For development (using water quality data in 2012) and evaluation (using water quality data in 2011) of regression models, we used water quality data from downstream of Yeongsan river basin during 2011 and 2012, and correlation analysis between TOC and water quality parameters was conducted. The concentrations of TOC were positively correlated with Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), TN (Total Nitrogen), Water Temperature (WT) and Electric Conductivity (EC). From these results, simple and multiple regression models for TOC estimation were developed as follows : $TOC=0.5809{\times}BOD+3.1557$, $TOC=0.4365{\times}COD+1.3731$. As a result of the application evaluation of the developed regression models, the multiple regression model was found to estimate TOC better than simple regression models.

  • Residentialization is in progress in the coastal areas of the cities as the number of apartment houses rapidly increase with the simultaneous provision-centered development. It would be necessary to provide quality residential environments which would not deteriorate and would be chosen by many people as a sustainable residence in the future through the demand-centered development, considering the residents' consciousness. To do so, it is necessary to understand the residents' consciousness about the residential environment in the coastal area that has differentiated characteristics as a waterfront space through an evaluation of the residential environment, different from the existing residences. This study understands the significance of the waterfront space in the residential environment through people's consciousness when they choose a residence before they reside and people's consciousness when they evaluate the residence after they reside, concerning how the environment of the waterfront space is recognized as compared to other elements of the residential environment according to the geographic characteristics of the coastal area. In addition, this study analyzes the significance of people's consciousness before and after their residence through a comparison according to the change of distance to the waterfront from the perspective of access to the waterfront, the characteristic as a residential environment in the coastal area.

  • The study aims to analyze and evaluate the evaluation items and application methods of environment-friendly middle schools in Chungbuk area by case studies. For the study, the criteria and situations of environment-friendly schools are analyzed literally and three environment-friendly middle schools in Chungbuk area selected. The field surveys and faculty interviews are performed. As results, about 35 environment-friendly technologies are applied and 66 to 68 points are acquired in three selected schools. It is analyzed that the PV, natural interior materials, raining recycle system and sufficient green spaces are pointed out as main technologies. About 66% of respondents know the environment-friendly certification and use the environment facilities in classes. However, the unsuitable plants for interior green spaces, unskilled management of recycling facilities and the absent of student participate programs show up as main problems. Also, the active campaigns need to expand the environment-friendly school.

  • Recently, the environmental sustainability has showed up one of the important considerations in the construction industry. However, the effective evaluation method for the decision-making on either reconstruction or remodeling of a project has not been developed so far. This paper presents an integrated evaluation model considering both environment and economic factors of a building project for which the decision making on either remodeling or reconstruction is needed. In order to develop the model, the characteristics of both types of projects were investigated and analyzed through the related literature review, and then appropriate evaluation criteria and analysis methodology to be used in the model were developed.

  • Over the years, there has been much research in blended learning. However, research regarding its use and evaluation is inconsistent, not following any specific evaluation method, and may not be applicable to local students. In this research, a case study was conducted to evaluate the environment based on three levels of Kirkpatrick's model. Methodological triangulation was the principle of data collection used in which multiple sources of evidence were triangulated to provide insights into this study. Instruments used include surveys, interviews, questionnaires and pre- and post-tests that are guided by Kirkpatrick's model. The results revealed that students were positive with the learning environment. Students enjoyed learning with multimedia and motivated to learn as well as engaged in the environment. The tests showed significant difference in their learning. Students also perceived that they have transferred their learning from face-to-face lecture into problem-based learning and learning outcome. This research contributes to the field by providing deeper insights into assessments in multimedia-based blended learning environment and empirical evidence on views, attitudes, learning and knowledge transfer of students in higher education.

  • The purpose of this research is to draw out the factors affecting the residents' evaluation on valuable animal and vegetation and the naturality of vegetation seen near regional environment. With this purpose, Questionnaire research and vegetation survey focusing on area of types of vegetation and species of big trees were made in 30 points of midstream of Tama River, Tokyo, Japan. The questionnaire research was based on basin environment units in order to be reflective of regional natural environment. The vegetation was classified into 5 types according to its flora and observed the covering area of each points and types through the aerial photograph. In addition, the species of big trees in habitat were listed by the survey. Results as below came out by analyzing the outcome of the questionnaire research and vegetation survey by multiple regression. First, residents are most likely not to distinguish precisely between the quantitative and qualitative aspects of vegetation. Both of the researches are apt to be influenced by quantitative factors of vegetation. Second, residents are assumed to consider forest of big trees, inhabitant of groups of big trees, highly natural.
