  • This study seeks a method to objectively evaluate sensibility based on Big Data in the field of design. In order to do so, this study examined the sensibility responses on design factors for the public through a network analysis of texts displayed in social media. 'Hanbok', a formal clothing that represents Korea, was selected as the subject for the research methodology. We then collected 47,677 keywords related to Hanbok from 12,000 posts on Naver blogs from January $1^{st}$ to December $31^{st}$ 2015 and that analyzed using social matrix (a Big Data analysis software) rather than using previous survey methods. We also derived 56 key-words related to design elements and sensibility responses of Hanbok. Centrality analysis and CONCOR analysis were conducted using Ucinet6. The visualization of the network text analysis allowed the categorization of the main design factors of Hanbok with evaluation terms that mean positive, negative, and neutral sensibility responses. We also derived key evaluation factors for Hanbok as fitting, rationality, trend, and uniqueness. The evaluation terms extracted based on natural language processing technologies of atypical data have validity as a scale for evaluation and are expected to be suitable for utilization in an index for sensibility evaluation that supplements the limits of previous surveys and statistical analysis methods. The network text analysis method used in this study provides new guidelines for the use of Big Data involving sensibility evaluation methods in the field of design.

  • Objectives: This study was to compare two healthy cities, Liverpool in England and Wonju in Korea, which evaluated healthy city projects and to reorient evaluation strategy which fits into Korean Healthy cities. Methods: Comparatives analysis was used by reviewing documents, healthy city plan and evaluation report, of two cities. Results: Healthy city projects in two cities, fifteen programs were identical items among twenty-seven but there were differences in seven items for Liverpool and five items for Wonju. In Liverpool evaluation was done by a stakeholder group called Liverpool Local Involvement Network(LINK), while in Wonju by Yonsei Healthy City Research Center. The evaluation tool was two types; quantitative and qualitative analysis. Liverpool mostly used qualitative and added quantitative, vice versa in Wonju. Conclusions: Evaluation plan for Healthy city projects need to be made in the first phase of the projects, instead of in the end. Moreover, it is important to include stakeholder in conducting qualitative analysis for unquantifiable evidence of effectiveness, as well as quantitative analysis.

  • The Government is putting efforts to enhance efficiency and productivity of performances of National R&D Programs by enacting 'Law on Evaluation and Management of Performances of National R&D Program'. This study is the result of development of evaluation model and indices for analysis of efficiency through meta evaluation method for the specific evaluation among evaluation systems for National R&D Program that are being carried out at government-wide level. Meta evaluation model for analysis of efficiency of evaluation system for National R&D Program designed evaluation indices by categorizing compositional factors into 5 categories, namely, evaluation context factor, evaluation resources factor, evaluation process factor, evaluation result factor and evaluation utilization factor. Furthermore, the result of verification of reliability on evaluation composition factors and evaluation indices analyzed to select evaluation items displayed Cronbach' $\alpha$ coefficient of 0.933, thereby illustrating that there is no major problem in the evaluation index system. In addition, computation of weight for each evaluation composition factor and evaluation index was analyzed by using analytical hierarchy process (AHP) technique. The result of analysis displayed overall consistency index of less than 0.1 for the investigators, thereby enabling analysis that there is consistency in investigators.

  • This study is to consider varying factors of internal/external informational and operational environments in libraries, and develop a new evaluation indicators for university libraries in digital environments. In order to do this research, the previous works have been investigated, and the Delphi study and our own analysis have been performed. The main research results are as follows. First, the results through the Delphi method that was to adopted to verify evaluation items and indicators determined by the literature review show that the repressed values for each evaluation category is greater than 3.00. overall average is 4.02. and standard deviation is ranged from 0.40 to 0.62 for each category. This means that the evaluation indicators are valid. Second, the factor analysis was performed to verify the construct validity of evaluation indicators. As a result. the cumulative variance of evaluation indicators consisting of 11 dimensions per factor is 72.733%. In turn, this result shows that the validity of these indicators is very reliable. Third, t-test and one way ANOVA are performed within significance probability 0.05 in order to verify differences in each librarians point of views for the degree of importance in evaluation indicators. The results show that these evaluation indicators are verified to be appropriate since there is no significant difference. Based on the Delphi study and our own analysis. we developed a new evaluation indicators that consists of 7 evaluation categories, 35 evaluation items, and 92 evaluation indicators.

  • This research This research aims at developing systemic evaluation model in terms of biotope preservation through reports, literatures, and expert survey analysis by implementing biotope structure analysis in area level with selecting Hyunpoong and Yuga-myeon, Dalseong county, Daegu metropolitan city as a site. First of all, as a result of biotope type classification of research site, biotope type groups are classified into total 13, and its biotope types are divided into total 61. Also, as a result of literature analysis, total 18 items are drawn such as diversity of biotope typical species as a index item to assess the preservation value of biotope, and the first evaluation index are divided into 10 and the second ones are divided into 8 according to characteristic of index items. As a result of expert survey analysis, All 10 index items, first evaluation index, show high importance average (above 4.7). As a result of implementation of main cause for categorizing evaluation index by characteristic, there are 3 factors such as 'obstructive factor.' Based on above survey analysis result, as a result of estimating the weight of each item, 'restoration factor' showed the highest, 3.4541, but 'factor of habitat stability' showed 3.1468, which is the lowest The systemic value evaluation was set by comprehensively analyzing these results. As a result of biotope preservation value evaluation through applying research site, total 19 types which are abundant in vegetation are classified into I class, 12 types in II class, 5 types in III class, 10 types in IV class, and 15 types in V class respectively. Lastly, as a result of second evaluation, it is analyzed that there are 17 special meaningful space to preserve species and biotope(1a, 1b) and 61 meaningful space to preserve species (2a, 2b, 2c).

  • Screening of estrogenic activity on dichloro diphenyl trichloroethane (DDT), dichloro diphenyl dichloro ethylene (DDE), dieldrin, heptachlor, aldrin, chlordane, lindane, polybrominated diphenyl ethers (PBDE) and parabens was compared using Organization for Economic Cooperation and Development (OECD) test guideline 455 (TG455). The estrogenic activity of DDT was 58,000-fold ($PC_{50}$, $1.67{\times}10^{-6}$ M) less than $17{\beta}$-estradiol($E_2$) ($PC_{50}$, $2.88{\times}10^{-11}$ M) but DDE, dieldrin, heptachlor, aldrin, chlordane, lindane and PBDE did not show any estrogenic activity in this assay system. In the case of paraben compounds, the rank of relative transcriptional activation (logRTA) was butyl paraben -1.63752 ($PC_{50}$, $1.25{\times}10^{-7}$ M) > isobutyl paraben -2.34008 ($PC_{50}$, $6.3{\times}10^{-7}$ M) > ethyl paraben -2.64016 ($PC_{50}$, $1.26{\times}10^{-6}$ M) > isopropyl paraben -2.73993 ($PC_{50}$, $1.58{\times}10^{-6}$ M) > propyl paraben -2.84164 ($PC_{50}$, $2.0{\times}10^{-6}$ M). Our data suggest that OECD test guideline TG455 may be useful as a screening tool for potential endocrine disruptors.

  • One of the activities to improve software quality in ISO 26262 is to apply the design principles for software unit design and implementation mentioned in ISO 26262-6, including the evaluation activity. Before evaluation activity, the tool is compared and selected for evaluation. Because the results of the tool a company selected might have an effect on product quality. In this paper, we suggest the method to compare industrial static analysis tools with some of "MISRA C : 2004 Exemplar Suite" and all lessons learned from comparing tools are described. The result on comparison shows that we just couldn't rely on a result of Static Analysis Tool and need to have another appropriate processes and guidelines to evaluate a software.

  • An extensive literature review has been made in this paper to build the evaluation hierarchy structure for the certification of electronic commerce services. In building the evaluation hierarchy structure, major candidate evaluation factors are selected by bench marking the various certification practices, including the Malcolm Baldrige award, ISO9000, and BSC(balanced scorecard) techniques. This paper deployed principal component analysis and factor analysis techniques to develop a statistically solid and systematic evaluation model. The final evaluation model, as presented in this paper as a model for the certification of electronic commerce services, produces a numeric score on the 100% scale, which can be served as a metric for the certification decision. The AHP technique was used in converting the various qualitative and quantitative evaluation values into a single measure for the certification decision.
